Description
- This application is a divisional of U.S. Ser. No. 10/858,385 filed Jun. 2, 2004, now U.S. Pat. No. 7,316,759, which is a continuation of U.S. Ser. No. 10/280,469 filed on Oct. 25, 2002, now U.S. Pat. No. 6,761,201, the entire contents of each of which are hereby incorporated by reference.
- The present invention relates to an apparatus for laying an adhesive strip Such as a sealant spacer strip along the peripheral edges of a glass sheet where positioning such a strip is one step in the assembly of an insulating glass unit.
- In general, the procedure for assembling an insulating window structure involves placing one sheet of a glazed structure, such as glass, over another in a fixed, spaced relationship, with a spacing and sealing means located at and along the periphery of the two structures, thereby forming a sandwich-type structure having a sealed air space between the structures. The sealed air space provides improved insulation capabilities. Difficulties exist, however, in the manufacture of the windows, especially the deployment and positioning of the sealant spacer strip.
- To keep the glazed structures properly spaced apart, a rigid spacer strip is formed into a frame and placed between the two structures to maintain proper spacing after which the sealant composition is injected into a channel formed by this spacer frame and the edges of the glazed structures. Alternatively, the rigid spacer can be pre-coated with sealant and placed into the space between the glazed structures to form the insulating window structure.
- Sealant spacer strips can be continuous whereby a single strip runs without interruption along the entire periphery of the glass sheet and has the flexibility to be bent into corners. When using flexible spacers, the degree of flexibility should be sufficient to permit a spacer to be bent around a corner. If it is not flexible enough, the spacer must be cut or notched to facilitate this bending. The manual application of a continuous strip, however, can require considerable ability on the part of the installer, especially to form consistent corners and if corners require notching, to properly place the notch. Also, continuous spacer strips may need to be removed and re-positioned, if the spacer strip is placed in incorrectly on the glass sheet.
- One conventional method of assembling or making an insulating window unit consists of starting at one corner applying an adhesive strip, typically a sealant spacer strip, along a peripheral edge of a glazed structure, forming corners where required, cutting the strip to length after formation of the last corner and then positioning a second glazed structure thereon to form a panel with an sealant spacer strip holding the glazed structures apart from each other.
- Applying the sealant spacer strip by hand can be time consuming and result in poor or inconsistent positioning of the sealant spacer strip. Also, the manufacturer must apply pressure by hand to get the sealant spacer strip to adhere to the glass sheet. The inconsistency of this pressure results in inconsistent adherence of the sealant spacer strip to the glass sheet.
- In order to alleviate some of these problems, application tools have been used to lay down sealant spacer strips on glass sheets. These tools require that the sealant spacer strip be threaded through the tool and must remain threaded in the tool until a complete assembly is fabricated. Many application tools make it difficult to reposition a mis-deployed threaded strip, because the device cannot be easily disengaged from the sealant spacer strip and re-deployed in the middle of fabricating an insulating glass unit. Instead the tool must be run back over the strip to the place of mis-deployment and then the strip re-positioned. This is often not possible forcing the window manufacturer to scrap the mis-deployed strip. Also, many of the tools do not provide capabilities for determining where the sealant spacer strip should be notched for cornering.
- It is an object of the present invention to provide a tool that easily applies the sealant spacer strip along the peripheral edges of a glass sheet.
- In one embodiment of the present invention, there is provided a hand application tool for applying a strip of material to a surface of a glass sheet or other member adjacent to the periphery thereof wherein the strip of material may be re-positioned if necessary.
- In yet another embodiment of the present invention, a hand application tool is provided having a guideway formed by a series of pins and rollers to enable the enable the precise deployment along the glass sheet periphery, formation of corners in the sealant spacer strip, provide consistent down-pressure for contacting the strip on the glass sheet and providing a means for easier for re-positioning of sealant spacer strip improperly deployed on the glass sheet.
- It is yet another object of the present invention to provide a guide plate and associated guide rollers for varying the distance between the edges of the glass members and the sealant/spacer strip.
- It is a further object of the present invention to provide an adjustable down pressure roller and an adjustable front positioning roller to accommodate varying thicknesses or gauges of sealant spacer strip.
- In another embodiment, a targeting system is provided which is capable of projecting an indicator light to aid the user in determining where the sealant spacer strip should be turned to form a corner and/or notched for cornering.
- In yet another embodiment, a cutting mechanism is provided for notching or cutting the sealant spacer strip in order to form corners.
- Other objects and the further scope of applicability of the present invention will become apparent from the detailed description given hereinafter. It should be understood, however, that this detailed description, while indicating preferred embodiments of the invention, is given by way of illustration only, since various changes and modifications within the spirit and scope of the invention will become apparent to those skilled in the art.

As can be best seen inFIGS. 2 , 3 and 4, at the end of thebase plate 24, opposite the handle support 22, the base plate has abase plate bracket 26. - The
base plate bracket 26 may be affixed to thebase plate 24 as a separate component or may be integral with it. Thebase plate bracket 26, as illustrated, generally has a lower portion connected to thebase plate 24 and a top portion affixed to and supporting thehousing 20. In this manner, these components form a frame for thehand application tool 16. - At end of the
handle 18 opposite thehousing 20 is anair inlet nozzle 28 capable of being connected to a source of forced air such as an air hose for activating a cutting mechanism. Of course, one of skill in the art will readily appreciate that any number of other electro-mechanical mechanisms may be used to drive the cutting mechanism. Also, not illustrated, but located in the vicinity of theair inlet nozzle 28 is a power coupling so that a power supply may be connected to thehand application tool 16. - The
hand application tool 16 has a series of rollers, guides and pins for deploying and positioningsealant spacer strip 14 ontoglass sheets 12. As can be seen inFIG. 3 , afront roller 30 is mounted on an axle of thebase plate 24 so that thefront roller 30 is freely rotatable about the axle. As can be seen inFIGS. 1 and 4 , on the opposing side of thebase plate 24 is located a second, correspondingfront roller 30 a.Front roller 30 a, like its counterpart, is mounted on an axle located on thebase plate 24 and is likewise freely rotatable about its respective axle. As can also be best seen inFIG. 1 , a set ofrear rollers base plate 24. - In one embodiment of the present invention, the
hand application tool 16 also has a series ofguide rollers guide plate 56. As seen inFIGS. 1 and 2 , a front guide roller is attached to the front of theguide plate 56, and thefront guide roller 36 may freely rotate about an axle. As illustrated, thefront guide roller 36 is oriented horizontally relative to the base plate. In other words, thefront guide roller 36 rotates in the plane perpendicular to the plane of rotation of the front andrear rollers front guide roll 34 36, amiddle guide roller 38 and arear guide roller 40 may be provided. At least two guide rollers are used for ensuring proper contact and spacing between thehand application tool 16 and the edge of theglass sheet 12. Themiddle guide roller 38 can be best seen in FIGS. 5 and 6. Therear guide roller 40 can be seen inFIG. 2 and is located towards the back edge of theguide plate 56, which in turn is attached to thebase plate 24. These rollers determine the position of the tool relative to the glass sheets. - As illustrated in
FIGS. 5 and 6 , thehand application tool 16 can also include a series of positioning pins 42, 42 a, and 43 attached to the housing and extending downward so that the pins are oriented generally vertically. In one embodiment, thepins pins pressure roller 52 andfront positioning roller 34 form a guideway for the accurate and consistent deployment of thesealant spacer strip 14. The guideway enables the user to turn thehand application tool 16 when deploying sealant spacer strip for the easy formation of corners within the strip. It also allows the user to remove thehand application tool 16 from the sealant spacer strip and re-position sealant spacer strip as necessary, which is particularly advantageous when the user is only partially finished deploying the strip. Conversely, thehand application tool 16 can be easily re-positioned on a sealant spacer strip already adhered to theglass sheet 12 to finish deploying the strip and forming the insulating glass unit. - As can also be seen in
FIG. 5 is the cutting mechanism of an embodiment of the present invention. In one embodiment, the cutting mechanism comprises ablade 44 capable of back and forth movement generally parallel to theglass sheet 12 within a slot orblade guide 46 and contacting with ananvil 48. The cutting mechanism can be activated by a blade activation knob or button 50 powered by the air supply or any other known means for reciprocating a blade. The cutting mechanism may also have different cut depth activation buttons. In this embodiment, for instance, by activating the first activation button, thesealant spacer strip 14 is notched so that it can be bent to form a corner. It is notched by partially cutting into thesealant spacer strip 14. In this case, thecutting blade 44 stops short of the anvil. If the second activation button is activated, thecutting blade 44 extends further to totally cut off thesealant spacer strip 14. This cut is performed at the final corner of the insulating glass unit to complete deployment of thesealant spacer strip 14. - To further aid in the deployment of the
sealant spacer strip 14, in one embodiment the hand application tool may also include a down-pressure roller 52 for placing pressure on thesealant spacer strip 14 during dispensing. As can be seen inFIGS. 3 and 5 , the down-pressure roller 52 rotates on an axle partially contained within a slot in the underside of the housing. The down-pressure roller 52 forms part of the previously described guideway. The adjustable axle or shaft is ultimately connected to a down-pressureroller adjustment knob 54. By turning the down-pressure roller adjustment knob, the down-pressure roller 52 may be moved up or down within the down-pressure roller channel 52. The down-pressure roller is spring loaded so small variations in sealant spacer strip height can be maintained while keeping the downward pressure on the sealant spacer strip generally uniform. In operation, the down-pressure roller exerts pressure on thesealant spacer strip 14 to adhere it to theglass sheet 12. - To further aid in the positioning and deployment of the sealant spacer strip, the hand application tool may also include an
adjustable guide plate 56 to provide a means for laying the sealant spacer strip a proper distance from the edge of the glass sheet. By maintaining contact between the edge of theguide rollers guide plate 56 and theglass sheet 12, the user is able to control the proper spacing of the sealant spacer strip from the edge or periphery of the glass sheet. - In order to adjust the
guide rollers plate adjustment knob 60 is turned to move the guide plate back and forth across the bottom surface of the base plate until theguide rollers glass sheet 12 at the desired distance so that the sealant spacer strip is applied at the desired location on theglass sheet 12. Once the desired position is attained, thescrews guide plate 56 in place and deployment of the sealant spacer strip may proceed. - Attached to the front of the housing is a
front positioning roller 34. In one embodiment, as illustrated inFIGS. 1 and 2 , thefront positioning roller 34 can be attached to the housing via anadjustable attachment 62 such as a screw or bolt in a slot. If the screw or bolt is loosened, thefront positioning roller 34 can be slidably moved within a slot or groove in theattachment 62. Once the desired height for thefront positioning roller 34 is found, the screw or bolt can be tightened to frictionally engage the outer surface of the attachment. Of course, one of skill in the art will readily appreciate that other types of attachments that allow adjustment of the height of the front positioning roller may be used. - The
hand application tool 16 of the present invention may also have a targeting system to alert the user where thesealant spacer strip 14 must be notched and where to form corners. The targeting system may comprise a set oflaser ports lasers 66. As can be further seen, thelaser 66 is activated by a laser control switch (not shown). By activating the control switch, thelaser 66 is turned on and light indicator beams are sent out theirrespective laser ports hand application tool 16 that is easily seen by the operator. Besides lasers, any other known optical beam may be used for this purpose. - In operation, the
sealant spacer strip 14 is applied to the top face of theglass sheet 12 by inserting thestrip 14 underneath thefront positioning roller 34 and between the positioning pins 42, 42 a and 43 to contact the down-pressure roller 52. The user then rolls the hand toll along the work table supported by the front andback rollers guide rollers sealant spacer trip 14 to be deployed above and in front of thetool 16 so that the top surface of thesealant spacer strip 14 engages thefront positioning roller 34. As thesealant spacer strip 14 is deployed, it is guided by the positioning pins 42, 42 a and 43 laterally andfront positioning roller 34 vertically, moves through the guideway and vertically engages the down-pressure roller 52, which serves to apply a pressure on thesealant spacer strip 14 to secure it to theglass sheet 12. - The targeting system allows the user to watch the indicator lights projected from the
laser ports hand application tool 16 has reached a corner and thesealant spacer strip 14 needs to be notched and then where thehand application tool 16 needs to be turned or pivoted. In other words, thefirst laser port 64 projects an indicator light beam that is easily viewable by the user to show the user where thesealant spacer strip 14 should be notched. The user aligns the first indicator light with the edge of theglass sheet 12, provided the angle of the corner is ninety degrees, and then activates the cutting blade activation button 50 to notch thesealant spacer strip 14. The user then moves thehand application tool 16 along thesealant spacer strip 14 until the second indicator light beam from thesecond laser port 64 a aligns with the edge of theglass sheet 12. At this point, the centerline of the down-pressure roller 52 will be immediately above the notch. The user pivots thehand application tool 16 about this the centerline of down-pressure roller 52 to form a corner in thesealant spacer strip 14. The process is then repeated for the next side of the glass sheet. - While in accordance with the patent statutes, the best mode and preferred embodiment has been set forth, the scope of the invention is not limited thereto, but rather by the scope of the attached claims. Although the invention has been described above in relation to specific forms, it should be evident to the persons skilled in the art that it may be modified and defined in various ways and should not be limited in interpretation, except by the terms of the following claims.
