Description

[Detailed description of the invention] [Industrial field of application] The present invention is applicable to door frames, for example, to which a clogging is attached.
This invention relates to an instrument for inserting a filler into a T-slot of an object such as a door, window frame, or window sash.

[Conventional technology]

Fillings of the type having a backing material and a sealing material upright from the backing material are known in the prior art. In this common form of plugging, the sealing material is a band-like material flocked with elastic fibers. As a typical example of this type of closing, 1965
No. 3,175,256 filed by R. C. Horton on March 30, 2007, the publication of which is incorporated herein by reference. The filling described in the Horton patent is sold under the trademark "Fin Seal," and is a thin, impermeable, flexible material that is affixed to the backing material and located within the flocking band. It is characterized by a protective piece made of plate material. Conventional plugging, in its more rudimentary form, omits the aforementioned guard strips.

In any case, generally speaking, the filling inserted into the T-slot by the device according to the invention comprises a lining material, upright from this lining material, fixed to this lining material, and on both sides of the sealing material. It includes a sealing material extending longitudinally from the backing material spaced inwardly from the outer edge of the backing material to define a flange. This filling is preferably of the type described in U.S. Pat. No. 4,458,450, issued July 10, 1984, which is incorporated herein by reference. In this filling, there are cracks or similar weak streaks extending partially into the interior of the backing from the back side of the side of the backing over which the sealing material is spread.

Such fillings are commonly installed in T-slots of objects such as metal or plastic extrusions or profiles. The T-slot includes a longitudinally extending groove having a width less than the width of the groove and having a longitudinally extending opening communicating with the groove. When the filling is inserted into the T-slot, the backing material is seated within the groove, the flange retains the filling within the groove, and the sealing material protrudes from the opening.

[Problem that the invention seeks to solve]

Conventionally, this type of filling is drawn into the T-slot by an endless belt device carrying a clamp fixed to the free end of the filling, and as the belt moves parallel to the T-slot, the filling is drawn into the T-slot. I was drawn into it. This type of device is described in a U.S. patent filed August 15, 1957, filed by M.H. Ellenberg et al.
Published in issue 3335487. One disadvantage of this method is that as the length of the filling being drawn into the T-slot increases, the force required to pull the filling into the T-slot increases, and the filling cannot withstand this force. It may break. Another disadvantage is that this highly tensioned filling can shrink after it has been drawn sufficiently into the profile to be cut. A further disadvantage of this method is that the filler must first be placed manually into the T-slot. moreover,
Retraction devices of the type described above need to be somewhat longer than the length of the profile and may not be able to be used if the profile has a T-slot on the inside.

Another approach to inserting the filling into the T-slot includes using a machine that simply pushes the filling into the T-slot through the opening leading to the groove. The machinery to do this is relatively expensive.

[Means for solving problems]

According to the present invention, when the filling is inserted into the T-slot, excessive stress is not applied to it.
A simple and inexpensive filling insertion tool is provided, the length of which is very short, and further configured to be useful in situations where the T-slot is on the inner surface of a type of profile. I can do it. Aspects of the present invention are as follows. That is, the filling is determined by the T of the object to which the filling is attached.
An instrument for inserting into a groove, the filling includes a lining material and a device that stands upright from the lining material.
Encapsulant material affixed to the backing material and extending longitudinally from the backing material at inwardly spaced intervals from opposite edges of the backing material to define flanges on each side of the encapsulant material. The T-groove is of the type that has a seal when the filling is inserted into the T-groove, the backing material is located in the groove, and the flange holds the filling in the groove. a longitudinally extending groove with a longitudinally extending opening having a width narrower than the width of the groove and communicating with the groove such that the material protrudes from the opening, the device having one member; The member is positioned with respect to the object such that the member and the object can undergo relative movement in the longitudinal direction of the T-groove, and further includes lateral movement of the member with respect to the object during the relative longitudinal movement of the member. a guide means for cooperating with the object to prevent the material from forming, and further comprising a guide path for receiving and delivering the material into the T-slot, the member covering the T-slot and forming the material in the object. slopes downwardly with respect to the T-groove when placed on top, and terminates at the outlet of the surface of the member that contacts the object and the T-groove, and one of the flanges of the backing material passes through the outlet of the member and terminates in the T-groove. a guideway angled to hold the backing material relative to the T-slot at an angle such that the member can pass through the opening of the T-slot and into the T-slot; and the other side of the flange to T
It includes means upstream of the outlet that can engage the other side of the flange for movement through the opening of the groove and into the groove.

〔Example〕

Referring to FIG. 1, there is shown an object 10, exemplified by an extrusion of rectangular cross section, to which a filling is attached. Object 10 is formed with a T-groove 11 having a width narrower than the width of groove 12, extending longitudinally, cocentric with groove 12, and communicating with groove 12 as shown. Opening 13
(Fig. 4-6) and has a groove 12 extending in the longitudinal direction.
(Figure 4-6).

The filling to be inserted into the T-slot 11 is 1 in Fig. 3.
4, which includes a seal that rises from the backing material, is secured to the backing material, and extends longitudinally from the backing material at a point spaced inwardly from the side edges 17 and 18 of the backing material. It includes a backing material 15 with a fastening material 16. As a result, the backing material 15
includes flanges 19 and 20 on either side of the sealing material 16 which allows for the flocking of elastic fibers as described above. In this embodiment, the filling 14 is fixed to a backing material 15 made of an impermeable, flexible sheet material, and the guard strip 2 is arranged in a sealing material 16.
It also includes 1.

The filling 14 happens to be located on the flange 19 and on the underside of the backing material 16, i.e. on the sealing material 16.
From the side opposite to where it spreads, insert the backing material 16
a crack 22 extending partially through the
The illustrations are of the type described in the aforementioned co-pending patents.

After the filling 14 is inserted into the T-slot 11, the backing material 15 is placed in the groove 12 and flanges 19 and 20 connect the filling 14 to the T-slot 11, as best shown in FIG. The sealing material 16 passes through the opening 13 while holding the object 1 in place.
0 protrudes higher than the surface 23.

As shown in FIG. 1, a filling insertion instrument 24 according to an embodiment of the present invention is arranged such that the instrument or tool or member 24 and the object 10 can move relative to each other in the longitudinal direction of the T-slot. A position can be taken against. In one illustrated embodiment of the invention, member 24 moves relative to object 10;
Its direction of movement is indicated by arrow 25.

The member 24 includes a slider 26 and a slider 26
It includes a handle 27 which is secured to the handle 27.

As shown in FIG. 4, a T-shaped member 29 that fits snugly into the T-slot 11 protrudes from and forms part of the lower side 28 of the slider 26. The function of this T-shaped member 29 is that the member 24 and the object 10
The slider 26 cooperates with the object 10 to prevent lateral movement relative to the object 10 during relative longitudinal movement between the slider 26 and the object 10. Those skilled in the art will recognize that other types of guidance means may be used for this purpose. However, in addition, the T-shaped member 29 is particularly suitable because it prevents the member 24 from being jerked upwardly away from the object 10 during relative longitudinal movement; This results from the fact that flanges 30 and 31 of T-shaped member 29 are prevented from lifting out of T-slot 11 by flanges 32 and 33.

A guide path 34 is provided within the slider 26. The cross-sectional shape of the guide path 34 is preferably similar to the shape of the filling 14, and furthermore, the sealing material 1
6 and a cavity 36 in which the lining material 15 is accommodated.

As shown in FIG.
When in working position relative to the object 10, i.e. when positioned over the T-slot on the upper surface 23 of the object 10, the guideway 34 is inclined downwardly relative to the T-slot 11 and the object 10 It terminates in an outlet 37 on the lower surface 28 of the slider 26 abutting the upper surface 23 and the T-slot 11.

As best shown in FIG. 5, the guideway 34 is also angled relative to the T-slot 11 such that the flange 20 of the backing material 15 can pass through the opening 13 and into the groove 12 via the outlet 37. It is tilted.

Member 24 further includes roller bearing 4
It includes a freely rotatable pressing ring 38 which is fixed to a shaft 39 mounted on the shaft 39. As best shown in FIG.
can be engaged with the flange 19 to force it to pass through the opening 13 and into the groove 12 . Those skilled in the art will realize that other means can be used for the same purpose as pusher ring 38, such as, for example, stationary fingers.

When working on the member 24, as shown in FIG. 1, the T-shaped member 29 is inserted into the T-slot 11.
Furthermore, the sliding member 24 is moved in the direction indicated by the arrow 25 by T.
It is attached juxtaposed to the object 10 by sliding in the longitudinal direction of the object 10 parallel to the groove 11. It is noted that the inlet 41 of the guide channel 34 is downstream (with respect to the direction of the arrow 25) from the outlet 37 of the guide channel 34 from which the filling 14 emerges when it is being inserted into the T-slot 11. Will. Similarly, the pressure ring 38 is upstream of the outlet 37.

With the member 24 and object 10 juxtaposed as shown in FIG. Go down the guide path 34 in the order shown in FIG.

As best shown in FIG. 5, the slope of the guideway 34 relative to the T-slot 11 is such that the backing 15 is supported at an angle where the flange 20 extends through the opening 13 and into the groove 12. It is a great angle.

As the sealing material 14 moves from the position shown in FIG. 4 to the position shown in FIG. It moves downwardly into the cavity 35 with the result that the flange is finally forced into the groove 12.

Finally, the pressing ring 38 contacts the flange 19 facing the crack 22 and forces the flange 19 through the opening 13 and into the groove 12. This is facilitated by the backing material 15 bending at the cracks 22.

In the embodiment described above, movement of member 24 relative to object 10 is accomplished manually by grasping handle 27 with the hand and pulling member 24 in the direction of the arrow relative to the stationary object. However, this operation can of course be mechanized, and either or both of the object 10 and the member 24 can be moved mechanically.

To reduce friction between member 24 and object 10, a short region, e.g. 1/2 inch, of the lower end of member 24 may be replaced with a suitable plastic material such as Teflon. Additionally, both flanges 30 and 31 of the T-shaped member 29 are provided to facilitate fitting the T-shaped member 29 into the T-slot.
may be removed only in the range of the tip.

Generally, the member 24 made of metal, such as GRD D2 tool steel, may be provided with a coating of, for example, titanium nitride, to make the member 24 more slippery with objects and more resistant to wear.

〔Effect of the invention〕

It is contemplated that a filling insertion tool embodying the present invention could be manufactured from injection molded plastic. In this case, the tool would be disposable after wear.

When using this tool to attach filling to an inner groove, it is desirable to change the attachment position of the handle 27 so that it comes out from one side of the member 24 rather than from the top surface.

Having thus described one selected embodiment of the present invention, those skilled in the art will appreciate that modifications can be made to this embodiment without departing from the spirit and scope of the invention as claimed. You should be convinced that it is possible.
