Description
~ - 2~3768 STRIP APPLYING HAND TOO~ WITH CORNER FORMING APPARATUS
This invention relates to a strip applying tool for applying strip material to a pair of opposed substrates and more particularly, it relates to a strip applying tool which includes a punching device for removing a portion of the strip to form a corner therein simultaneously during the application procedure.
Numerous strip applying tools have been proposed in the art, however, these tools have limitations in that many of them incorporate a superfluous amount of moving parts all of which are susceptible to mechanical failure. In addition, during an application procedure of strip material to a substrate and more particularly, when a corner needs to be formed in the strip, the procedure using known tools, must be interrupted and the corner formed therein. As such, this not only has a negative impact on productivity, but additionally provides a potential "weak spot" in terms of the insulation capacity of the strip.
Accordingly, there exists a need for a strip applying tool which permits the formation of a corner in strip material during a continuous uninterrupted application to a substrate. Applicant, with the present invention, addresses this need and in one aspect of the present invention provides a hand tool for applying strip material to a substrate comprislng:
a body having a lower surface with a channel~0 extending therethrough for receiving strip material therein;
a substrate positioning member adjacent the channel on the lower surface of the body for guiding the tool along an edge of the substrate;
at least one pressure roller rotatably mounted within the body in operative association with the channel for pressurably applying the material approximate to the edge of the substrate; and 20~37~
a guide wall associated with the channel for guiding the strip material, the guide wall being inclined relative to the lower surface and spaced therefrom a distance less than the width of the strip whereby the lower surface of the tool is elevated from the substrate.
The strip material generally includes materials such as butyl polymers, silicones, polyvinyl polymers and other such insulating bodies for application to substrates e.g.
glass lites for fabrication of insulated glass assemblies.
The positioning member may comprise any material which provides low friction enabling the lower surface of the body to slide freely along an edge of the substrate without substantial wear; a suitable material to achieve this purpose may be, for example, TeflonTM.
The strip feeding channel of the tool includes a guide wall which is angularly inclined relative to the lower surface of the tool. Rollers at the forward and rearward ends of the guide wall provide pressurable application of the strip to the substrate.
The width of the strip if preferably greater than the distance between the guide wall and the rearward roller.
In this arrangement, the lower surface of the tool remains out of contact with the substrate thus avoiding any marring or scratching of the substrate surface.
The tool according to the present invention additionally permits the user to form a groove within the strip to allow the same to pivot. This feature allows the formation of "corners" in the strip simultaneously during an application procedure. Thus, according to a further aspect of the present invention, there is provided a hand tool for applying strip material to a substrate comprising:
3 ~37~8 a main body having a lower surface with a channel associated therewith for receiving strip material;
a substrate positioning member adjacent the channel on the lower surface for guiding the tool along an edge of the substrate;
a guide wall associated with the channel for guiding the strip material, the guide wall being inclined relative to the lower surface and spaced therefrom a distance less than the width of the strip material whereby the lower surface of~0 the tool is elevated from the substrate;
at least one pressure roller rotatably mounted within the body in operative association with the channel for pressurably applying the material approximate the edge of the substrate;
a slidable punch member slidably mounted within the body adapted to remove a portion of the strip to form a pivot point therein, the punch member being slidable from a first non-punching position wherein the punch member is spaced from the strip to a punching position wherein the punch member is~0 within the strip; and actuation means to effect movement of the punch member between the first and second positions.
The slidable punch member is preferably mounted adjacent the front end of the body in operative association with the strip feeding channel. The punch member provides a hollow punch for removing a section of the strip material from the strip to provide the pivot point i.e. corner while the strip is fed through the channel in an uninterrupted manner.
The pivot point is spaced inwardly from the outer surface of the strip so that the strip remains continuous thus contravening energy loss at this point.
To effect severance of the strip material once the four sides of a substrate have had strip material applied thereto, there is provided a blade member connected to the punch member. For a cutting procedure, the blade is movable ~ 4 2Q~37~8 transversely relative to the punch member. This movement made be effective by a manual handle having a linking member extending within the body to link the handle with the blade.
The punch member may be actuated by any suitable means e.g. manually, pneumatically or hydraulically. In a preferred form, the actuation of the punch will be achieved by the use of a pneumatic force.
The blade member may include a projecting element to remove strip material from the punch thus preventing the punch area from becoming jammed with removed strip material.
According to a further aspect of the present invention, there is provided a method of placing a strip of material proximate an edge of a substrate comprising the steps of:
providing a length of sealant strip from a supply thereof;
providing a hand tool having a lower surface and strip feeding channel therein angularly inclined to the lower surface;
feeding a length of the strip into the channel;
effecting securement of the strip to the edge of the substrate; and cutting a groove within the strip to facilitate securement of the strip around a corner edge of the substrate.
Having thus generally described the invention, reference will now be made to the accompanying drawings illustrating preferred embodiments and, in which:
Figure 1 is a side view of the hand tool of the present invention;
Figure 2 is a partially cut-away side view of Figure l;
~ ~ b, 3 7 6 8 Figure 2 is a partially cut-away side view of Figure l;
Figure 3 is a front elevational view of Figure 2;
and Figures 4A, B and C are sequential views of the blade member during a punch material removing and strip cutting procedure.
. Referring now to Figure 1, the hand tool, generally represented by numeral 10, includes a handle 12, a central body portion 14 and lower surface 16, the latter including a positioning member 18 extending the length of the lower surface 16. The positioning member 18 preferably comprises a tough material, e.g. wood, for sliding and guided contact on the peripheral edge of the substrate while the tool is moved and guided therealong to apply the strip material to the substrate.
Referring now to Figure 2, in which the opposite side of the tool is shown to that of Figure 1, the tool includes a plate 20 connected to the central body portion 14 in spaced relation thereto by fasteners 22. The spaced relationship of plate 20 relative to body portion 14 defines a open ended channel and is sufficient to permit passage of sealant strip material 24 therethrough. Adjustment of fasteners 22 permit a change in the width of the channel to accommodate differently sized strip material.
A ~I ward guide member 26 guides strip material 24 in the channel bt;lweell plate 20 and body portion 14 and more particularly, over punch stop means 28, which comprises further guide member for elevating the strip of the substrate and guiding it to the substrate surface. The stop means 28 is inclined relative to lower surface 16 by an angle ~. The stop means 28 directs the strip material 24 downwardly and beyond lower surface 16 (di~cllssed in further detail hereinafter).
A rearwardly directed pressing pin 30 extends from within body 14 and through plate 20.
Pin 30 is adjustable via a fastener 32 such that same may be urged into contact with strip 24 to permit the strip to extend beyond the lower surface of the tool 10 to prevent contact of the surface 16 with a substrate (not shown) on which the strip is being placed. The pin 30 may rotate to permit easy transportation of strip 24.
Mounted to the tool 10 ~djac~nt main body portion 14 is a pnellm~tic cylinder 34. A
primary fluid line 36, which is adapted for connection with a fluid supply source (not shown), supplies pressurized air to the cylinder 34. An actll~ting switch 38 is positioned intermediate line 36 and cylinder 34. An inlet hosing 40 extends from switch 38 to an inlet 42 on cylinder 34.
Outlet hosing 44 extends from outlet 46 on cylinder 34 to switch 38.
A piston 48 is slidably mounted within cylinder 34 for reciprocal movement. A punch member 50, which is inclined from the vertical by angle ~ for squarely meeting the punch stop, and, having a guide 52 ~ 0 4 3 7 6 8 is mounted to an end of piston 48 and facilitates guided movement of punch 50 between body portion 14 and plate 20.
The punch member 50 comprises a hollow cylindrical member, shown in side view in Figure 4A, 4B, and 4C, for removing a generally semicircular portion of strip material 24 from the strip material. This feature permits the strip to be bent or flexed about a corner when the same is encountered during the application of the strip material to a substrate.
The cylindrical punch 50 includes an arcuate opening 54 to permit the discharge of semicircular portions of the strip material from within punch 50. To this end, opening 54 may be directed toward the front of the tool 10 to enable the discharge of the portions from between body portion 14 and plate 20. The forward end of central body 14 may have a portion removed to provide an enlarged area to further assist in clearing the discharged portions from the tool 10.
A slot 56 is included on cylindrical punch 50 for selective cooperation with a cutting blade.
A cutting blade 58 is provided and is movably mounted within central body portion 14. This is generally illustrated in Figure 3. The blade 58 is mounted for upward and downward movement relative to the longitudinal movement of the stop material. A spring 60 is connected between the blade 58 and within body portion 14 at 62. The spring 60 biases the ' 8 ~ a 4 37 6 8 blade 58 to the upward position as illustrated. A cutting edge 64 is provided on blade 58 as well as a projection 66 adapted for cooperative engagement with slot 56.
An actuating member 68 is provided on body portion 14 for displacing blade 58 laterally relative to the upward or downward movement. A biassed link extends between member 68 and blade 58.
In operation, strip material 24 is fed between plate 20 and body portion 14 over guide member 26 and the strip 24 applied to a substrate (not shown) while maintaining lower surface 16 out of contact with the substrate with the exception of the guided contact along a peripheral edge.
Upon reaching a corner in the substrate, rather than severing the strip at the point, the user actuates the punch member 50 by depressing switch 38. This effects movement of the punch member 50 from the non-punching position illustrated in Figure 2, to the punching position shown in dotted lines on the same drawing. The punch member 50 abuts punch stop means 28. Once a semicircular portion is removed switch 38 is released and the punch member returns to its non-punching position. When the user reaches the final corner of the substrate, the strip must be severed. This is achieved by making use of actuating member 68. When punch member 50 is in a non-punching position, blade 58 is laterally moved by actuating member 68 such that projection 66 of blade 58 , ~. , .
~ 20~3768 engages slot 56 of member 50. The actuation of the punch member 50 is then carried out as previously set forth. During this procedure, blade 58 moves in concert with punch member 50, the blade abutting stop means 28 and severing the strip material.
