Description

TITLE: APPARATUS FOR THE REDUCTION OF TOBACCO SMOKE
The present invention relates to an apparatus for the reduction of tobacco smoke produced in a closed environment, and in particular, to apparatus for the removal of "second hand smoke" from gambling tables at casinos.
The conventional manner of dealing with the problem of second hand smoke has been to enjoin the use of tobacco in its entirety. However, since smoking in casinos is an inherent part of the gambling milieu, prohibiting smoking in its entirety can result in loss of patronage and damage to the establishment. Another attempted solution has been to provide increasingly stronger apparatus' for ventilating such rooms. Such equipment is not only larger, but is more costly and complex both in installation and in use.
It has been found that the conventional apparatus, normally placed within the ceiling of the casino, is only partially effective in removing all the smoke. Such equipment removes air, and, therefore, whatever smoke found in it is from the upper level of the room. It is significantly less effective in capturing and removing the smoke and especially the particulates in the smoke from the lower half of the room, particularly smoke produced and found on the level of the patrons producing such smoke. It is the smoke in this space which is most detrimental to smokers and non-smokers as "second hand smoke" .
It is an object of the present invention to provide an apparatus which acts to capture the smoke as it is generated by the smoker while seated at a gaming table and transmits the smoke to the upper levels of the room to be handled by the ventilating equipment.
It is another object of the present invention to provide casinos and similar establishments with equipment to remove smoke immediately upon its creation from relatively confined rooms or areas such as poker rooms and baccarat pits.
These objects together with other objects and advantages are set forth in the following disclosure.
According to the present invention, the apparatus comprises a smoke removal chimney assembly for receiving smoke. The chimney assembly is mounted in a box like container, open at its top, and slidably supported to hang from the undersurface of the table adjacent the seat or table at which the patron sits. The container is slidable out from beneath the table to a position adjacent the seat whereupon the patron may raise the chimney assembly to a position adjacent the patron's face. The chimney assembly comprises a duct-like cylinder provided with an opening into which the patron expels the smoke. The cylinder is elongated, rising to a height above the head of the user when sitting at the gaming table. At the upper end of the duct, there is provided a fan which sucks the smoke up and then propels it to an upper level beyond the 5 ft. rise, toward the ventilating system before being recirculated.
The chimney assembly is mounted within the box container to be supported in balance by a pair of platforms movable by one or more telescoping supports and one or more spring loaded cables so that when lifted, the assembly is stable and balanced, obviating any care or concern on the part of the patron, except to use the same. Full details of the present invention are set forth in the accompanying drawings and the following description.
Fig. 1 is a side elevational view showing a player seated at a casino table to which is attached the housing in which is contained the smoke removal device of the present invention;
Fig. 2 is a side elevational view showing the apparatus of the present invention nested in its housing, the front panel of the housing being removed;
Fig. 3 is a view similar to Fig. 2 showing the chimney apparatus extending upward from the housing;
Fig. 4 is an enlarged exploded view of the apparatus of the present invention showing the details thereof;
Figs. 5A, 5B and 5C are enlarged views, partially sectioned showing the details of the telescoping supports; and
Fig. 6A and 6B is an exploded and enlarged view of the chimney and ashtray employed in the present invention.
As seen in Fig. 1, the smoke removal apparatus, contained in a box like housing generally depicted by the numeral 10, is illustrated as depending from the lower surface of a casino poker table 12. It will be appreciated, however, that the invention may be applied to other tables not only within the casino, but elsewhere, such as bingo halls where people congregate for long periods.
As seen in Figs. 2-4, the housing 10 is provided with a pair of rectilinear side walls 14, a bottom wall 16, a
SUBSUME SHEET IBUIE 26) front wall 18 and a rear wall 20. The front wall 18 is provided with an elongated slot 22, the purpose of which is to be described later. The housing is open at its top.
The housing 10 is hung from the lower surface of the table 12 by a pair of slide mechanism 24 each having one part secured to the table and another to the exterior surface of the side walls 14 adjacent the upper edge of the housing. In this manner, the housing 10 may be stowed beneath the table (dotted lines, Fig. 1) when the apparatus is not in use and pulled forwardly adjacent the patron when used, as seen in full lines in Fig. 1.
Located within the housing 10 is an elevator and support assembly, generally depicted by the numeral 30, and which carries the smoke removal chimney assembly, generally depicted by the numeral 32.
The elevator and support assembly 30 comprises a ferrous metal bottom platform 34 having a length and width almost equal to the bottom wall 16, but sufficiently free of contact with the side and end walls 14, 18 and 20 to allow the platform 34 to move freely upwardly and downwardly. The lower platform 34 is provided with a handle 36 protruding through the elongated slot 22 to permit manipulation of the platform. If desired, this handle may be used as well to pull the housing out from beneath the table.
To insure that the platform 34 remains horizontal and that it is prevented from canting during its movement, each of the side walls 14 is provided with a pair of linear trackways 38, one adjacent the rear wall 20 and one adjacent the front wall 18. The trackways 38, on one wall, are in opposition to those on the other wall. The trackways 38 are U-shaped channel members opening inwardly of the housing. Attached to the side edges of the platforms 34, in registry with each of the trackways 38, is a bracket 40 which slidably fits into the opening in the U-shaped trackway. The trackways 38 and the brackets 40 are made from suitable low friction materials or combinations so that lifting of the platform is unhindered. For example, the slide bracket 40 may be made of nylon while the trackways 38 may be aluminum. Mounted at the top of each of the trackways 38 is a stop member 42, the purpose of which is to limit the upward movement of the platform 34. Preferably, the stop members 42 are magnets and hold the lower ferrous platform firmly in its upper position. If the lower platform is not made of a ferrous metal, but is made of aluminum, then the stop member 42 will be made of a ferrous metal and will meet several magnets 48 located on the top surface of the platform and corresponding in position to the stop members.
To reduce the weight of the platform 34 and the mechanisms carried on the platform, a pair of constant force cables 44 are spaced on each side of the platform 34. Each constant force cable 44 is attached at one end to a spring device housed in a small container 46 secured to the bottom wall 16 of the housing 10, and its other end entrained over a lower pulley 50, an upper pulley 52 and terminally secured to the platform 34. The edge of the platform 34 is notched at 54 to provide for free movement of the cable 44 and for room to anchor the free end. As seen in the drawings, the cables 44 on one side of the platform need not be directly opposed to those on the other side since the cables are employed to overcome weight and not to stabilize or orientate the platform and its load.
Mounted on the platform is a quadrilateral array of four elevator supporting posts 60. Each post 60 comprise a set of decreasing diameter tubes set one within the other in slidable telescoping manner. The lower most or largest tube is set within a recess 62 formed in platform 34 and firmly secured by welding, screws, bolts, or the like so as to be extendible in a vertically fixed position. Mounted on the upper end of the uppermost post 60, (i.e., to each of the smaller tubes) is a second platform 64 which is smaller in length and width than the lower platform 34. This upper or second platform 64 is firmly fixed to the tubes 60 as by welding or the like to extend cantilevered toward the rear wall 20 and parallel to the side walls 14 so that a platform extension 66 extends laterally over the lower platform 34.
As seen in Fig. 5A, 5B and 5C, each post 60 comprises three slidingly telescoping tubes 60a, 60b and 60c. A pair of hollow junction or fitting 68 is provided to connect the smallest and the intermediate tubes 60c and 60b and the intermediate and largest tubes 60b and 60a, respectively. Each fitting 68 comprises a stepped cylindrical member having an upper portion 70 and a lower portion 72 offset to provide a shoulder 74. The upper portion 70 is adapted to be force fit or swagged within the lower end of the smaller tube 60c and the lower end of the associated intermediate tube 60b, while the lower portion 72 has a diameter slightly smaller that the next larger tube so that it slides relative to the wall of the larger tube. The larger tube of each associated pair is provided with an inwardly rolled edge 76 forming a stop against which the shoulder 74 of the fitting 68 seats preventing the tubes from separating when fully raised. The larger or lower portion 72 is provided with a pair of spaced apart recesses 78 in each of which a ball 80 is held and is also provided with a small horizontal slot 82 on a line with recess 78 when the tubes are fully extended, (i.e., raised) so that the ball 80 can fall and detent within the slot 82, thus acting to lock the tubes in place in the extended position. Passing through the hollow fitting 68 is a piston like element having a conical base 84 integral with a piston rod 86. The piston rod 86 is biased in an upward, (i.e., raised) condition by a compression spring 88 bearing against the end of the upper portion 70 of the fitting and is held by a pin 90. In this normally biased mode, the conical base forces the ball 80 to seat firmly in the slot 82.
The telescoping supports are arranged in pairs to either side of the center line of the housing, in each of these pairs, one support may be denoted as the master and be provided with means by which the telescoping tubes may be releasibly fixed in their upward or extended position. The other support pair, need not carry such means, and can, therefore, be denoted as a slave support.
Preferably, the supports are arranged diagonally to each other, each row having a master and slave, as indicated by M and S, respectively. These master supports will be provided, as seen in Fig. 5A, with an elongated rod 92 which is placed within the smallest tube 60c, being held therein by a collar 94 into which a radial pin 96 is seated. The pin 96 extends radially outward through a longitudinal slot 98, which holds the rod 92 in the tube 60c while permitting the rod 92 to be longitudinally moveable. The upper end 100 of the rod 92 extends through a removable washer like cap 102. When the rod 92 is depressed, it acts against piston rod 86 which causes its conical base 88 to also move downwardly against its normal bias to release the balls 80 unlocking the smaller and intermediate tubes. The smaller tube then collapses into the intermediate tube until it also depresses the piston rod of fitting in the intermediate tube. This causes the piston to and its base to simultaneous effect the unlocking of the intermediate tube 60b from the largest tube 60a to permit the intermediate tube to collapse into the largest tube. It is, of course, appreciated that the collapse of the tubes causes the chimney assembly to be carried downwardly to the inoperative position against the lower platform, the lower platform being still in its upper position.
To manually effect unlocking of the tubes in each of the paired supports, a finger grip ring 104, Figs. 1-4, is pivotally fastened to the uppermost tube 60c of the slave supports and rests in abutting fashion on top of the other support tubes. By simply squeezing the ring 104 downwardly toward its upper platform, Fig. 3, the rods 92 will be depressed in both masters causing the unlocking action to be effectuated.
Depending from the lateral extension 66 is the smoke removal chimney assembly 32. The chimney assembly 32 comprises an upper duct 110 in which is located a movable lower duct extension 112 so that the two ducts can be fully extended. The lower duct extension falls automatically as the smoke removal device is lifted into the operating position and is collapsed as the device is restored into the housing as the closing of the telescoping supports causes the bottom of the lower duct to engage the lower platform 34. The duct extension 112 and a part of the upper duct 110 have a chordal opening of about one-half of the circumference in which smoke may be blown (see Fig. 1) . The bottom 113 of the extension 112 is provided with an ashtray 114.
The upper duct 110 is connected to the lateral extension 66 of the upper platform by a swivel joint 116 comprising a ring neck 118 fixedly secured to the open end of the duct 110 for conjoint rotation. Rotatably fit over the neck 118 is a collar 120 which is itself fixedly and staticly attached to the lateral extension 66 by bolts or screws passing through flanges 119 and tabs 122. The lateral extension 66 is provided with a cut out opening 124 aligned with the neck 118 and collar 120 to allow free flow of air from the duct 110.
The collar 120 is provided with a peripheral slot 126 through which passes the shank of a thumb screw 128 which is removably secured in the neck 118. In this way, the neck and collar are rotatable relatively within the range of the slot 126 and may be easily disconnected one from the other by removal of the set screw 128. The set screw 128 also serves as a handle for manually turning the neck and entire chimney. It will, of course, be appreciated that other forms of swivel joints can be used. The chimney cylinder and duct may be turned right or left in an approximately 180° arc allowing the duct and ashtray to be positioned in the most convenient location for the user, i.e. 45° relative to the direction the user is facing, and also allowing adjacent players to use the smoke removal device alternately.
An exhaust fan 130 is located above the cut-out opening 124 formed in lateral extension 66. This facilitates the movement of the air through the chimney. It may be desirable to mount a further extension 132 or the like above the fan 130. Such an extension may be advantageously, a tubular member having a curving reduced interior 134 forming a venturi-like nozzle acting to propel the smoke to a height selected to be above the breathing level of most people.
Finally, a micro-switch 140 is mounted on the upper surface of the platform adjacent the front panel 18 and a tab 142, functioning as an actuator is mounted on the front panel 18. The switch is connected in a non- conventional manner to an external source of current and via a conduit 144, passing through one of the slave support posts to the fan 130. Thus, when the platform 34 is lifted into its functional or operating position, the fan is automatically started. If desired, the micro- switch 140 can also be connected to a light or other electrical device to show that the smoke remover is operating.
In the enlarged, exploded view of Fig. 6A and 6B, the details of the ashtray 114 employed in the present invention is shown as well as its mounting in the lower duct extension 112. The bottom 113 of the lower duct extension 112 is in the shape of a horseshoe allowing space for the insertion of the user's finger or fingers, while providing a stable shelf on which the ashtray 114 removably sits. The ashtray comprises a semi-circular body 150, having a peripheral wall 152 for holding the ash and waste. The interior of the body 150 is provided with a separating wall 154 to define distinct areas, respectively, one for ash and one for stubbing out the cigarettes, the latter being filled with sand or the like. The ashtray 114 is provided with a cover 156, having a flat rigid bottom 158 on the back 160 of which is hinged a cover flap 162. The back wall 160 is designed so that when the bottom 158 and cover 162 are placed parallel to each other, the ashtray body 150 fits snugly there between. In this manner, the ashtray can be inserted within the lower extension 112, stably and properly seated on the bottom wall 113, the cover flap 162 being then pivoted to expose the interior of the ashtray for use (Fig. 6A) . When the ashtray is full and must be changed, the cover flap is replaced over the top of the body so that the ashtray can be manually removed and replaced with a clean assembly. Because the cover flap 162 closes the ashtray, the attendant is protected against burn, and the waste and ash is prevented from falling out. If desired, the bottom 158 of the ashtray assembly may be provided with a magnet 164 cooperating with the ferrous bottom wall 113 for additional security in holding the ashtray. The smoke removal device according to the present invention is normally stowed beneath the table, out of the patrons way and hidden from view. When a smoker/patron seats himself at the table, he grasps the handle and at first pulls the entire housing out from beneath the table until it stops adjacent his seat. There upon, the patron in a non-critical sequence, grasps the upper platform and lifts the entire chimney assembly, extending the telescoping tubular supports and/or continues with manipulation of the handle to lift the platform until the platform reaches the top edge of the housing and engages stops. In either sequence, the chimney assembly is raised to the level of the patron's face where he is able to expel smoke directly into the ducts. Simultaneously, the fan is started and the smoke is removed as seen in Fig. 1, when the patron leaves the apparatus is stowed by placing the cover back on the ashtray, turning the chimney with the thumb screw back to its original position, and then reversing steps by squeezing the release ring.
Various modifications and changes have been disclosed herein, and others will be apparent to those skilled in this art. Therefore, it is to be understood that the present disclosure is by way of illustration and not limiting of the present invention.
