Abstract
A lighter has been integrated into portable electronic equipments such as cellular phones, PDAs, or portable game players. The lighter can be completely stowed within the portable electronic equipment so that no parts protrude out of the portable electronic equipment's housing. Thereby not only the size can be reduced but also damage and entanglement with other things the portable electronic equipment is kept together as well as injuries can be avoided. The lighter is operated by a switch which is implemented as button either on the side of the portable electronic equipment or as a GUI menu or button on the display unit. When pressing the switch button the cover on the outlet of the lighter is being removed while at the same time a cylinder is being extended and moving out of the outlet, and a flame ignited in the burner unit appears from inside of the cylinder. The lighter includes a fuel tank which can be either fixed or removable as for instance fuel gas cartridges. A function for detecting the fuel gas amount and displaying it on the screen and a security function to lock the burner of the lighter are also provided.
Description
- 1. Field of the Invention
- The present invention is related to portable electronic equipment, for-example, cellular phones, PDAs, and game players, and more particularly to portable electronic equipment with integrated lighter.
- 2. Description of the Related Art
- Recently, portable electronic equipment, especially cellular phones have become so widespread and the number of people carrying electronic equipments, especially cellular phones, PDAs (personal digital assistants), and game players have much increased in urban areas. The functions of portable electronic equipment also have become so diverse in these days. For example, a cellular phone is not only equipped with the conventional function of transmitting and receiving voice or data but also has got functionality even of a camera and a-remote controller. Much more functions are expected to be added and hence cellular phones and other portable electronic equipment are becoming portable all-purpose equipment.
- For the sake of omitting the description of various functions and items of portable electronic equipment, a cellular phone is taken as a general representative example of portable electronic equipment in the following description.
- Whenever new and convenient functions and accessories are added to a cellular phone, the original function is maintained and can be fully used while the number of the items that you usually would carry separately with you is reduced. This reduces the weight and the volume of your belongings, thereby making it easy to accommodate the cellular phone with all functions and accessories in a bag or a pocket. At the same time as the number of items that you carry with you is decreased, the probability that you leave something behind or forget or even lose something is reduced.
- When someone goes out leaving his house or apartment, he or she always carries the key with him or her. When instead of a key, a cipher signal used for an electronic lock that is wirelessly transmitted to the lock from a cellular phone, the conventional key is not necessary anymore, hence, the number of the carried items can be reduced. Similarly, when functionality of a cash card for a bank is provided by a cipher signal modulated on a wireless signal, it is not necessary anymore to carry a cash card that can be easily forgotten or lost.
- A lighter is one of the items very often that are carried in pockets or bags. A lighter is used for example to light a cigarette. Provided that you are a smoker it may be a nuisance when you have left the lighter behind or lost it. When a lighter is mounted on a cellular phone, it is possible to prevent from losing or leaving it behind. A conventional technique in which a lighter is mounted on a cellular phone is disclosed in the Japanese Patent Utility No.3091568 (page. 7 to 10,
FIG. 1 andFIG. 5 ) (hereinafter, referred to as the article 1). - In
article 1, a method has been proposed, for attaching a lighter to the distal end of an antenna of a cellular phone with a screw so that it can also be removed again. However, when using it or when attaching it to the screw or removing it there from, there is a danger that the antenna body may be deformed and bent by the weight of the lighter, which may cause the interruption of transmission and reception. - Another embodiment of the
above article 1 shown inFIG. 13 depicts a conventional technique for preventing from interruption of transmission and reception. As illustrated inFIG. 13 , a structure has been proposed in which the antenna body is removed and instead of the antenna, anexternal lighter 10 is directly mounted on thehousing 11 of acellular phone 1 by a screw thread connection. Anignition button 101 for the external lighter is provided on the lateral side of theexternal lighter 10 and ignition is triggered by pushing this button. - In the above-described conventional techniques, a lighter is mounted onto the housing of a cellular phone in a way that it is protruding from the phone housing, which is a serious problem. When putting the cellular phone with the protruding lighter into a trouser pocket, there is a danger of damaging or injuring you. When putting it into a bag, there is a danger that the protruding part gets entangled with other things and thereby damaging the bag and the other things.
- In the conventional technique shown in
FIG. 13 , it is possible to prevent from interruption of communication caused by bending the antenna. However, when removing the lighter in order to refill it with liquid gas, it may be left behind or lost again. Further, in order to use the lighter, the antenna has to be once removed before the lighter can be attached on the housing, which is troublesome. - In order to solve the above mentioned problems of the prior art, an objective of the invention is to provide portable electronic equipment including a lighter which can prevent from leaving behind and losing a lighter by integrating the lighter into the portable electronic equipment, e.g. a cellular phone.
- Another objective of the invention is to provide portable electronic equipment including a lighter in which, since a lighter is built into the equipment, the lighter can be always carried along without leaving it behind when it has been removed from the equipment. And when a user carries the portable electronic equipment putting it into a pocket and a bag, injury to the user and damage of the equipment caused by entanglement with cloth or thread of the bag can be prevented by integrating the lighter completely into the equipment to make the surface of the portable electronic equipment even without any projection.
- Yet another objective of the invention is to provide portable electronic equipment including a lighter which size can be reduced while increasing the number of functions.
- Further another object of the invention is to provide portable electronic equipment including a lighter which can be refilled with fuel and where the remaining amount of fuel can be easily checked.

FIG. 1 is a perspective view of a cellular phone according to a first embodiment of the invention; FIGS. 3 to 5 are perspective views respectively showing the states of the integrated lighter for use in this embodiment at the time of non-operation, before ignition at the time of operation, and at the time of operation and ignition;FIGS. 6 and 7 are cross sectional views showing the details inside the integrated lighter respectively at the time of non-operation and the time of operation and ignition; andFIG. 8 is a cross sectional view of the fuel tank and the fuel cartridge in the integrated lighter according to the first embodiment. - In the following embodiments, a description will be made by taking a cellular phone as a representative example of the portable electronic equipment.
- With reference to
FIG. 1 , acellular phone 1 of the first embodiment is formed by aclamshell housing 11 capable of folding around a hinge, ascreen 12 for display is provided on one inner surface of the foldedhousing 11, and akey operation board 13 including amenu key 131 and aselection key 132 is provided on the other surface. On the rear side of thescreen 12 of thehousing 11, aintegrated antenna 14 is embedded in the portion near the hinge and a integrated lighter 3 is embedded in the distal end portion of the housing opposite to the hinge. - In this first embodiment, it is preferable that an extensible antenna body or a fixed antenna body protruding outward from the
housing 11 is removed and the antenna body is integrated into the housing by using an antenna realized on a print board disclosed in, for example, Japanese Patent Publication No. 2908432, a wire antenna spiraled in the housing, or an antenna realized by a circuit embedded into a thin film board or a flexible print board. - The structure of the integrated lighter 3 is described as follows. A
slide switch 4 for ignition is provided on the lateral side of thehousing 11 of thecellular phone 1 in order to operate the integrated lighter 3. An outlet hole of aburner 30 is provided on the top lateral surface of thehousing 11 in order to let out fire from the integrated lighter 3. Further, aburner cover 31 is provided for opening and closing theburner 30. As illustrated inFIG. 1 , aslide switch 4 for ignition is normally placed at the upper position and theburner 30 is covered with theburner cover 31 and closed. - Hereinafter, the detailed structure of the integrated lighter 3 will be described with reference to
FIG. 3 ,FIG. 4 , andFIG. 5 .FIG. 3 ,FIG. 4 , andFIG. 5 show the portion of the integrated lighter 3 on the rear surface of thehousing 11 of thecellular phone 1. In the first embodiment thefuel tank 5 is a cartridge type fuel tank. - The
slide switch 4 for ignition is in the upper position, as illustrated inFIG. 3 , in the state where theslide switch 4 for ignition is not in the operation. At that time, theburner 30 and avent 35 nearby are closed, being covered by theburner cover 31.FIG. 4 shows the state of the integrated lighter 3 when theslide switch 4 for ignition moves downward. As soon as theslide switch 4 for ignition moves downward, theburner cover 31 is drawn to the left, hence thevent 35 is opened, and at the same time, a burnerextensible cylinder 32 is lifted out from theburner 30. As illustrated inFIG. 5 , when theslide switch 4 for ignition is pushed in at the lower position, a flame comes out of the burnerextensible cylinder 32. Unless theslide switch 4 for ignition is pushed in at the lower position, it never lights. Needless to say, the burnerextensible cylinder 32 and theburner cover 31 are made of state of the art heat resistant and non-burnable material. - Though the burner
extensible cylinder 32 is formed in a circular cylinder in this embodiment, it may be formed in a rectangular cylinder as far as the cylinder is extensible. - The operation of the integrated lighter 3 of the first embodiment will be described with reference to
FIG. 6 andFIG. 7 .FIG. 6 shows the state in which the integrated lighter 3 is not operated, whileFIG. 7 shows the state in which the integrated lighter 3 is operated and ignited. - At first, the details of the normal idle state of the non-operating integrated lighter 3 will be described with reference to
FIG. 6 . Alower support spring 41 mounted on a switchlower partition 421 pushes theslide switch 4 for ignition upward until theswitch 4 reaches a switchupper partition 422 by repulsion in expanded state. At this time, acompressive spring 431 also pushes theslide switch 4 for ignition outward through a first forcetransmissive part 432 by repulsion in expanded state. Simultaneously, a fueltank switching part 43 is moved away from a fueltank switching lever 44 by repulsion of thecompressive spring 431 of the switch and the tensile force of a fueldischarge opening spring 55 closes thecover 53 of a fuel discharge opening of thefuel tank 5. As mentioned above, when theburner cover 31 covers theburner 30 and thevent 35, the burnerextensible cylinder 32 is shrunk and drawn back into thehousing 11. - When a user wants to operate the integrated lighter 3, at first, the
slide switch 4 for ignition is put down with the finger. When theslide switch 4 for ignition is put down, it borders on the upper portion of the switchlower partition 421 and stops there. When theslide switch 4 for ignition is put down, anextension activating part 34 transmits a signal to anextension operator 33 and theextension operator 33 opens theburner cover 31 to let the burnerextensible cylinder 32 extend from theburner 30. Theextension activating part 34 may be realized by, for example, a mechanism of precision instrument, chain or line, or a wire for electrically transmitting a signal. - The details of the operation and the function at the time of putting a light with the integrated lighter 3 will be described with reference to
FIG. 7 . When theslide switch 4 for ignition is held at the lower position by the finger and pushed inward to thehousing 11, the fueltank switching part 43 is pushed rightward and the left side of the fueltank switching lever 44 is pushed down. Thus, the right'side of the fueltank switching lever 44 is lifted up and thecover 53 for the fuel discharge opening connected to the right side of the fueltank switching lever 44 is opened. When thecover 53 of the fuel tank discharge opening is opened, fuel gas starts flowing into the upper space from thefuel tank 5 and finally flows out of thehousing 11 from theburner 30, after passing through the burnerextensible cylinder 32. - When the
slide switch 4 for ignition is pushed inward to thehousing 11, the force compresses thecompressive spring 431 of the switch through the first forcetransmissive part 432 and applies a force onto apiezo ignition system 6 through a second forcetransmissive part 433. The force causes electrons to flow into anignition electrode 61 owing to the piezoelectric effect within thepiezo ignition system 6. When the electric field of the final end of theignition electrode 61 and the inner surface of the burnerextensible cylinder 32 exceeds a certain value (about 30 kV/cm), discharge occurs and instantly sparks are generated. These sparks ignite the fuel gas flowing from thefuel tank 5 and a desired flame comes out of the burnerextensible cylinder 32. Oxygen is transmitted from theopen vent 35 through avent tube 36 so that the flame does not extinguish. - When the finger releases the force on the
slide switch 4 for ignition, theslide switch 4 for ignition is returned leftward by repulsion of thecompressive spring 431 of the switch and further returned to the upper normal idle position by a repulsion of thelower support spring 41. At this time, by the fueltank switching part 43 being pushed leftward and by the tensile force of the fuel tankdischarge opening spring 55, the fueltank switching lever 44 is returned to the parallel position and thecover 53 of the fuel tank discharge opening is closed. A fuel tank discharge opening packing 54 seals thecover 53 of the closed fuel tank discharge opening, hence stops the outflow of fuel gas from thefuel tank 5 and the flame extinguishes. When theslide switch 4 for ignition is returned upward, theextension operator 33 draws back the burnerextensible cylinder 32 through theextension activating part 34, returns theburner cover 31, and closes theburner 3 and thevent 35. - Next, the structure of the fuel tank, a method of fuel supply and-a method of confirming the fuel amount according to the embodiment will be described with reference to
FIG. 3 andFIG. 8 . - The integrated lighter 3 of this embodiment has the
fuel tank 5 of cartridge type.FIG. 5 shows a fuel tank cover 51 for thefuel tank 5 of cartridge type, which is positioned at the rear surface of thehousing 11 of thecellular phone 1. Thefuel tank cover 51 is opened by sliding it rightward while pushing a specified portion by the finger. On the contrary, the openedfuel tank cover 51 is closed by sliding it leftward until it is locked. A transparent fuelamount confirmation window 52 is provided in thefuel tank cover 51, so that a user can confirm the fuel amount of the fuel tank (cartridge) 5 easily. When there remains a little fuel, the fuel tank cover 51 can be opened and thefuel cartridge 8 inside thefuel tank 5 can be replaced. As thefuel cartridge 8 reusable type that can be refilled or disposable type may be used. -
FIG. 8 shows the details of the connection of thefuel tank 5 for cartridge with thefuel cartridge 8 according to the first embodiment. Thefuel cartridge 8 is formed by a fuel cartridge opening and closinglid 81 which opens inwardly into thefuel cartridge 8, aninner packing 82 for sealing the lid in a state in which the fuel cartridge opening and closinglid 81 is closed, acompressed spring 85 for the fuel cartridge opening and closing lid, astand 86 for the spring of the fuel cartridge opening and closing lid, for fixing thesame spring 85 at the lower portion (the other end of thespring 85 is fixed to the fuel cartridge opening and closing lid 81), an external spring packing 83 which prevents thefuel gas 87 from leaking out when the cartridge is connected to thefuel tank 5 of thecellular phone 1, and alocking bolt 84 attached to the fuel tank to connect it to thefuel tank 5 of thecellular phone 1. - Accordingly, when the above
fuel tank cover 51 is opened so to insert thefuel cartridge 8, the lockingbolt 84 of thefuel cartridge 8 is inserted between a fuelcartridge sealing part 57 of thefuel tank 5 and the packing 58. In this case, the lockingbolt 84 is engaged into the notch part of the fuelcartridge sealing part 57 and snaps in there. Hence the chambers of thefuel tank 5 and thefuel cartridge 8 join together. While they are joined, the fuelcartridge sealing part 57 pushes down the fuel cartridge opening and closinglid 81 so to open it and thefuel gas 87 fills the chamber of thefuel tank 5. Since the packing 58 is neatly engaged with the external spring packing 83, thefuel gas 87 will never leak out of thefuel tank 5 or thefuel cartridge 8. Thecover 53 of the fuel discharge opening is usually sealed and closed by the extensible fueldischarge opening spring 55 fixed on thestand 56 in thefuel tank 5 and the fueldischarge opening packing 54. Since theseating plate 56 is interspersed withseating holes 561, thefuel gas 87 can expand and reach thecover 53 of the fuel discharge opening without trouble. - When the
fuel gas 87 of thefuel cartridge 8 becomes a low of fuel gas or empty, the upper portion of thefuel cartridge 8 can be slightly pressed by two fingers to release the lockingbolt 84 from the engaged position and, thus, thefuel cartridge 8 can be removed away easily for refilling or disposal. - A second embodiment of the invention will be described, this time.
FIG. 2 is a perspective view of a cellular phone according to the second embodiment. - The second embodiment is different from the first embodiment shown in
FIG. 1 in that an external antenna is used, instead of theintegrated antenna 14 in thecellular phone 1 of the first embodiment, and the other components are the same as those of the first embodiment. - As illustrated in
FIG. 2 , in thecellular phone 1 of the second embodiment, ascreen 12 for display is provided on one inner surface of theclamshell housing 11 which can fold around a hinge and akey operation board 13 including amenu key 131 and aselection key 132 is provided on the other surface. - On the rear side of the
screen 12 of thehousing 11, a integrated lighter 3 is embedded in one distal end portion of the housing opposite to the hinge and anexternal antenna 2 is mounted on the other end portion. - Since the structure and the operation as for the integrated lighter 3 and the structure of the fuel tank and the fuel supplying method are completely the same as in the case of the above-mentioned first embodiment, the detailed description is omitted here.
- A third embodiment of the invention will be described.
FIG. 9 is a perspective view of a integrated lighter according to the third embodiment. - While the integrated lighters of the first and the second embodiments are furnished with a cartridge type fuel tank, the integrated lighter of the third embodiment uses a fixed fuel tank.
- As illustrated in
FIG. 9 , a fixedfuel tank 5 is set within the integrated lighter 3 which is mounted within thehousing 11 of thecellular phone 1. The structure and the operation of theburner 30 of the integrated lighter 3 and the structure and the operation concerned with theslide switch 4 for ignition are exactly the same in the case of the first embodiment. - Since it is the fixed
fuel tank 5, it is not necessary to open the rear side of thecover 11 of thecellular phone 1 and hence there is no fuel tank cover. To confirm the fuel amount, a transparent fuelamount confirmation window 52 is provided on thehousing 11. There is afuel supply valve 59 for supplying thefuel gas 57 under the fuelamount confirmation window 52. At normal time of supplying no gas, thefuel supply valve 59 is covered with a fuelsupply valve cover 591 and closed. Accordingly, it is possible to prevent from making ones clothes dirty. - A fourth embodiment of the invention will be described.
FIG. 10 is a cross sectional view showing the fuel pressure detecting portion of a connection adaptor with the fuel cartridge in the fuel tank according to the fourth embodiment. - As illustrated in
FIG. 10 , a ring-shapedpressure detecting portion 90 is mounted on the lower portion of the spring stand 56 in thefuel tank 5. Thepressure detecting portion 90 measures the pressure of thefuel gas 87, converts the information into a digital or an analog signal, and transmits it to aninternal state controller 73 described later inFIG. 12 through the pressure detectingportion signal line 901. According to this, theinternal state controller 73 converts the signal into the quantity corresponding to the pressure of thefuel gas 87 and stores the latest value. Since it is always possible to check the fuel amount, the amount of the fuel gas or refill request can be notified with icon or message on thescreen 12 of thehousing 11 of thecellular phone 1 or in the other method when there is onlylittle fuel gas 87 remaining or when it is completely finished. Theinternal state controller 73 supplies also power to thepressure detecting portion 90. -
FIG. 12 is a block diagram showing the detection of the amount of the fuel gas and the state of the notice control in this embodiment. The controller 7 of thecellular phone 1 controls the voice signal or data signal in the transmitting and receiving unit and also it connects with akey operation controller 71 of user interface or adisplay controller 72 for converting the information such as a message or image data into data for display or for theinternal state controller 73 to grasp and control the internal state and information. Generally, the controller 7 is implemented by a CPU, a DSP, or an applied integrated circuit or a combination of those. In this fourth embodiment, when the power of thecellular phone 1 is turned on, the controller 7 transmits a fuel amount measuring request message to theinternal state controller 73 in an idle state in which the other processing is not performed. In reply to this, theinternal state controller 73 transmits the data corresponding to the latest fuel amount to the controller 7 as a fuel amount measurement report message. - In spite of the idle state of the controller 7, the
internal state controller 73 periodically transmits a pressure measurement request message to thepressure detecting portion 90 and thus, thepressure detecting portion 90 measures the pressure of thefuel gas 87. The data of the measurement result is returned to theinternal state controller 73 via the pressure detectingportion signal line 901. Theinternal state controller 73 converts the pressure measurement data into a value corresponding to the amount of the fuel gas by using a table or a numerical expression and then updates and stores the above as the latest fuel amount data. - When receiving a fuel amount measurement report message, the controller 7 transmits it to the
display controller 72. Thedisplay controller 72 compares the fuel amount value taken out from the fuel amount measurement report message with the fuel amount table, converts the above into easy understandable icons like for instance full (90% and more), half and more (50% and more), 25% and more, a little left (5% and more), and empty (less than 5%), and displays these icons on thescreen 12. - Alternatively, after pushing the
menu key 131 of thekey operation board 13 and selecting the fuel confirmation menu, the fuel amount value can be displayed. When only little fuel gas remains (5% and more), it is possible to display an alarm message on thescreen 12. - A fifth embodiment of the invention will be described.
FIG. 11 is a cross sectional view showing the fuel tank cover lock portion of the connection adapter with the fuel cartridge of the fuel tank in the fifth embodiment. - In the fifth embodiment a
lock portion 91 to thecover 53 of the fuel discharge opening of thefuel tank 5 is added for safety purposes as illustrated inFIG. 11 . Thelock portion 91 is realized, for example, by a magnetic relay or by other opening and closing mechanisms. Power and a signal for setting the state of thelock portion 91 are supplied by theinternal state controller 73 via the lockportion signal line 911. Thelock portion 91 has two states including a lock state and an unlock state. When thelock portion 91 is set in the unlock state, thecover 53 of the fuel discharge opening will not open when operating theslide switch 4 for ignition. While, in the unlock state, the operation is the same as the operation of thefuel tank 5 having been described in the above-mentioned first embodiment. - In
FIG. 12 , the state of controlling the lock portion in this embodiment is shown by a block diagram. The operation of the fifth embodiment will be described with reference toFIG. 12 . - In a state of turning on the power in the
cellular phone 1, themenu key 131 is pushed on in thekey operation board 13 and then a safety lock operation menu of the integrated lighter 3 can be selected. The safety lock operation menu can set thelock portion 91 unlock or lock. In order to enhance the security, a personal identification number can be input so as to prevent from changing the respective states without authorization. - Alternatively, it is possible to display the state of the
lock portion 91 by using the icon on thescreen 12. By taking such security measures it is possible to prevent a non-authorized person such as an infant from misusing the integrated lighter 3. - In the above-mentioned embodiments, since the detailed display and the detailed description of the parts is more or less omitted on the drawings, although the mechanical or electrical operation is not described enough in part, it is not the essential problem of the portable electronic equipment with integrated lighter of the invention. The invention is not restricted to the structure of the above-mentioned embodiments but it is needless to say that various modifications can be added without departing from the scope of the invention.
- According to the invention, it is possible to prevent from leaving behind and losing a lighter by integrating the lighter into the portable electric equipment including a cellular phone. Further, since the lighter is built in, a situation that the lighter is removed and left behind never occurs and it can be always carried with the cellular phone. Since the lighter is completely integrated, the surface of the portable electronic equipment is always even without any projecting elements. Therefore, in the case where a user carries the lighter, putting it into a pocket or a bag, it is possible to prevent from injuring his or her body and damage caused by entanglement with thread of the cloth or bag or other things carried in the bag or pocket.
- Since the lighter is equipped with a replaceable cartridge or a fixed fuel tank with a supply valve for refilling fuel, it can be easily integrated into the portable electronic equipment. In the future, when a fuel cartridge for a small lighter is standardized, a reusable cartridge and a disposable cartridge will be available in the market, thereby enhancing the utility.
- Further, the fuel amount can be easily recognized from the window where the inside of the fuel tank can be seen and checked. Or even when the window cannot be provided there on the housing, it is possible to display the state of the fuel amount on a screen in the form of icon by using the pressure detector.
- Further, considering the security, it is possible to lock the fuel tank and make the lighter unusable for a non-authorized person such as an infant. The extensible cylinder where the flame comes out from the burner keeps the flame off the housing of the portable electronic equipment to prevent from damage of burning the housing of the portable electronic equipment.
- Although the lighter is applied to a clamshell cellular phone in the invention, it may be applied to a cellular phone of general type other than the above clamshell type and further, to the other portable electronic equipment, for example, a PDA (personal digital assistant) or a game player.
- Although the invention has been illustrated and described with respect to exemplary embodiment thereof, it should be understood by those skilled in the art that the foregoing and various other changes, omissions and additions may be made therein and thereto, without departing from the spirit and scope of the present invention. Therefore, the present invention should not be understood as limited to the specific embodiment set out above but to include all possible embodiments which can be embodies within a scope encompassed and equivalents thereof with respect to the feature set out in the appended claims.
