Description

DETAILED DESCRIPTION OF THE INVENTION The invention provides the following steps for joining two profile strips into a joining profile:
The present invention relates to a clamp member having a clamp jaw that performs a pressing locking action and a groove for engaging an edge portion of a joining section, and a method for joining joining sections using the clamp member.

In the known version, the clamping jaws, which are made of a heat-insulating material, provide a thermal isolation for the metal profile strips that are connected to a connecting profile.

(West German Patent Publication No. 2525968). The known technique is shown in FIG. 9, where the clamp jaw A
, B are moved to the clamp position by being pushed apart in the left-right direction in FIG. 9 by the rotation of the rotating core C. This configuration is uneconomical due to its multi-part construction and increases manufacturing, inventory and transportation costs.
SUMMARY OF THE INVENTION The object of the invention is to simplify the construction of a clamping element for joining two profile strips into a joining profile without reducing the stability in use.

This problem consists of a base plate that is arranged so as to be able to pivot in the direction of groove extension, a clamping surface that forms a clamping surface on the head side that is the pivoting side, and a clamping surface that is restrained in the clamping position by pressing the edge of the profile strip due to the pivoting. at least one clamping jaw.

In this case, the grooves serve to iron the greens of the profile strips,
Moreover, this groove only needs to be formed on at least one of the back surface of the base plate or the clamping surface of the clamp jaw. Further, the direction in which the groove is extended is a direction that substantially coincides with the direction of rotation of the clamp jaw. This type of configuration results in a clamp of a significantly simplified construction type.

Manufacturing costs can be saved, and inventory costs and transportation costs can also be lowered. It is also extremely easy to install. After the clamping jaws, which are flexibly connected to the base plate, are inserted into the profile strip, they can be swung into the clamping position by means of a special tool and are stopped in the position of the brackets, providing a high degree of stability in use. There is no risk of the clamp jaws loosening unexpectedly. This must be done consciously, especially in order to relax the clamp jaws by spreading them into their release position. Furthermore, in the above case, being restrained in the clamping position leads to fixation of the clamping member, which is advantageous. With relatively small clamping elements, it is therefore possible to create a stable connection of two shaped strips into one joining profile. According to the invention, two oppositely pivoting clamping jaws can also advantageously be provided.

Advantageous properties are obtained even more clearly if the head side of each clamping jaw consists of two roof-shaped opposed partial surfaces. One partial surface, the inner partial surface, is available for the loose connection of the profile strips.

This facilitates attachment of the clamping member. Only when the clamping jaw pivots into its resting position (positioned above the base plate and stabilized) does the other part surface,
The outer partial surface thus comes into engagement with the green of the profile strip. The locking position of the clamp jaw is maintained by a vertical web having a locking shoulder raised from the base plate surface, and the clamp jaw having a protrusion that is engaged under the shoulder. achieved.
It is advantageous in terms of assembly technology that the longitudinal webs have grooves on their upper sides for press-fitting of the edges of the strips.

The clamping jaws can therefore be associated with the profile strip in such a way that there is no unintentional movement of the clamping element into the profile strip before the clamping position is reached. As a result, the clamp members are accurately positioned. In this case, it has proven advantageous for the upper region of the longitudinal web in which the grooves are formed to undulate elastically (that is, to transition elastically).

Additional measures can therefore be dispensed with and do not interfere with the simple construction of the clamping jaws.

A particularly advantageous embodiment is one in which the pivotability is achieved by means of a film hinge.

When the clamping jaws are in the clamping position, there is only a negligible load on the film hinge section, which is indicative of a long life of the clamping member. As an auxiliary means for mounting the clamping element, a magazine rail can be used which accommodates the clamping element in the open clamp jaw position. This is like the binding needles in a stapler. Many clamp sections are arranged and stored in parallel in the magazine rail, and the first one is pushed into one side of the profile by pressure from the side. ,
(See Figure 4). This magazine rail allows the clamping member to be easily set in position. Finally, the base plate includes a corner piece, a T-shaped piece,
It has proven advantageous to be a cross-shaped piece or a similar piece.

With this method, a wide variety of connections of profile strips can be achieved in a simple construction. Furthermore, if a clamping member is used which has clamping jaws on an arcuately curved base plate, it is also possible to produce an arcuately curved coupling profile with a suitably shaped coupling profile. Embodiments of the present invention will be described in detail below with reference to the drawings.

The connecting profile 1 represented in FIG. 1 has metal profile strips 2 and 3 extending at a distance from each other. The mutually facing hook-shaped edges 4 and 5 of this profile strip are interconnected by a clamping element 6 which creates a thermal isolation. The edges 4, 5 of the profile strips fit into the grooves 7 and 8 of the clamping member. The clamping member 6 made of plastic and made by die-casting consists of a base plate 9 and a clamping jaw 10 which is pivotably connected to the base plate.

Pivotability is achieved by a film hinge 11 provided on the longitudinal edge of the base plate 9. Each clamp jaw
The head side of 10 is composed of two roof-like opposing partial surfaces 12 and 13.

These partial surfaces contain grooves 7, while the base plate
A groove 8 is formed on the back surface. clamp jaw 10
pivots relative to the direction of groove extension. In addition, as shown in FIG. 3, the clamp jaw 10 is stabilized in an oblique state such that the inner partial surface 13 of the clamp jaw 1 is parallel to the upper surface of the base plate 9. It is preferable that

This is achieved by appropriately selecting the rigidity of the film hinge 11. An elastic force acts on the clamp jaw 10 in this state no matter which direction it is turned. Therefore, when using the clamping member 6, the clamping jaws 10 are inserted into the edge 5 of the profile strip 3 in a stretched state and the clamping jaws 10 are pushed back into their original stable position.
When it is restored, it loosens and the bond is completed. A vertical web 14 is formed rising from the upper side of the base plate 9.

This vertical wave 14 is formed into a hook shape. Especially the 4th
As shown in the figure, the short angular web 14' is formed with its distal end generally coincident with the inner end of the groove 7 formed in the clamping surface of the clamping jaw 10, while the long angular web 14'
'' has a single groove 15 formed on its upper side, and a space between it and the base plate surface is formed below it.The long square web 14'' is elastically moved in the direction of the arrow 4, so that the clamping member associated with one profile strip 3 is held by the elastic clamping force and is displaced unintentionally, as shown in FIG. There isn't. The longitudinal web 14 is provided with a stop shoulder 16 with a running surface near its hem, which stop shoulder co-ruts with a projection 17 formed near the inner lower corner of the clamp jaw 10.

A slope 18 is attached to the projection 17. Preferably, before installation, the clamping element 6 is inserted into the magazine rail 19, which is represented in cross section in FIG. 5, with the clamping jaws 10 spread out.

This pressurized clamping member 6 is then removed from the magazine rail by means of compressed air or a lever press.
is press-fitted into the When the clamping member 6 leaves the magazine, the clamping jaw 1 pivots back into its starting position represented in FIG.
First, it is inserted into the groove 7 of the inner partial surface 13 and into the groove 8 on the back surface of the base plate. At the same time, the edge 5 of one profile strip comes into engagement with the groove 15 of the elastic longitudinal web 14, achieving a clamping of the clamping element 6 on the profile strip 3. After one or several clamping elements have been clamped onto a profile strip 3, the other profile strip 2 is pressed so that the two profile strips are loosened and a connection is already achieved.

This is followed by a clamp jaw and compressed air.
Alternatively, they are pressed against each other by tongs, in which case the grooves 7 of the outer partial surface 12 of the clamping jaws engage. In the clamping position, the groove 7 of the partial surface 12 runs approximately parallel to the plane of the base plate 9, so that a return pivoting of the clamping jaw 10 is prevented. For this purpose, a projection 17 of the clamping jaw is additionally used, which exceeds the resting surface of the stop shoulder 16 by means of a bevel 18 and engages below the shoulder. In this position, as shown in FIG. 2, the clamp jaws 10 are supported above the base plate 9 to achieve a stable unit. Therefore, only a small force acts on the film hinge 11. FIG. 6 shows a bonded profile utilized in a window.

20 represents the sash frame, and 21 represents the wing.

The profile strips 22 and 23 of the sash frame 20 are held by two clamps 6 arranged one above the other at a distance from each other for stable fixation, while the profile strips 24, 24 of the wing 21 ', individual clamping jaws 6 arranged at a distance from each other are sufficient. According to FIG. 6, it can be seen that the clamp is covered with a coating 25. This is a band of flexible material that can optionally be passed around corners. The structure of the fastening of two joined sections represented in FIG. 7 is formed by two corner pieces 26 and 27 arranged one above the other.

These distal parts form the base plate 9';
A clamp jaw 10 is rotatably provided on the base plate. Base plate 9' also clamp jaw 1
0 also penetrates into the edge of the profile strip and creates a stable corner connection. Figure 8 shows the horizontal crossbar butt joint or T
Type binding is represented.

It is made by means of a T-piece 28, which in its distal part forms a base plate 9', from which a pivotable clamping jaw 10 emerges. Note that it is possible to form the clamp jaw on a cross-shaped piece.

Furthermore, it is also conceivable to connect the clamp jaw 10 to the end piece extending in an arcuate shape.
