Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improved joint for assembling a side surface of one profile against a corresponding side surface of another profile, and more particularly, the present invention relates to an improved joint for assembling a side surface of one profile against a corresponding side surface of another profile. It is applied to fabricate the retaining structure of partition walls.

Assembling systems are known in which the sections are fixed to each other by means of joints introduced into one section and brought into contact with the other section, but known systems of this type generally result in incorrect assembly and It has the disadvantage that play remains between them, and on the other hand, its implementation is time-consuming and technical, requiring the drilling of screw holes in very precise locations on the profile.

The present invention seeks to correct these drawbacks of known joints.

The joint according to the invention aims to eliminate the risk of producing defective assemblies by automatically carrying out the appropriate tightening of the profiles.

Another object of the invention is to simplify the implementation of the assembly process.

For this reason, the joint according to the present invention, in which two sections are assembled by bringing the side surface of one section T into contact with the surface of the other section M, which has a group R, is suitable for being placed inside the section T. The main body part of the shape and the mold material M
a rigid first member including a front tenon portion of the main body portion having a cross section that is conjugate with the cross section of group R, and the main body portion has a recess that opens at the rear thereof; a suitably shaped rigid second member disposed at least partially within the recess of the body and guided axially by the body, the second member being disposed within the slot; carries a retractable pin which is arranged to slide in a direction substantially perpendicular to the axial direction of the main body, the pin being associated with a spring which directs the pin towards the opposite wall of the profile T. a rigid second member that protrudes beyond the main body of the first member and is configured to allow the pin to enter and fit into a hole P provided in the opposing wall of the mold material T; means for relative movement of the first and second members configured to slide the two members longitudinally relative to the first member in the direction of the tenon of the first member.

As will be explained further below, the coupling according to the invention is a functional monolithic structure, the installation of which is simple and rapid;
Additionally, complete assemblies with excellent mechanical resistance can be constructed.

According to a preferred embodiment of the invention, the relative driving means of the members are screwed into threaded holes made in the body of the first member so as to open into the recesses of the first member. The device includes a pressure screw and an inclined surface disposed at the front of the second member so as to push the second member forward in response to the pressure of the pressure screw.

Hereinafter, the present invention will be described in detail with reference to embodiments shown in the drawings.

The joint 1 illustrated in each of the accompanying drawings consists of two cylindrical sections (
(designated T and M, respectively), in such a way that one T is in contact with the side surface of the other M).

The profile T can be a horizontal member, and the profile M can be a vertical member.

The profile M is provided with a receiver group R on at least one surface thereof,
This group particularly exhibits an inverted alihozoic cross section.

On one side of the mold material T, adjacent to its end, there are firstly a hole P having the function of tightening the mold material T to the mold material M as described later, and a second hole P.
A slot L1 is provided for the insertion of an operating wrench for tightening both profiles, and thirdly, as an option, a further slot L2 is provided for carrying out a safety fixation if required. .

Note that these holes P and slots L1 and L2 can be made without special care and their positions do not have to be extremely precise.

The joint 1 mainly consists of two rigid members 2 and 3, the latter being partially inserted into the latter.

The member 2 includes a main body part 2a of an appropriate shape that can be placed in the hollow part of the mold material T, and a tenon part 2b having an inverted dovetail-shaped cross section that is conjugated with the cross section of the group R of the mold material M in front of the main body part 2a.
The body part 2a is provided with a rearwardly open recess for accommodating the front part of the member 3 and guiding it in the axial direction of the body part.

In this embodiment, in order to reduce the weight of the member 2, its main body 2 is
a is partially provided with an opening on the upper side and the lower side.

Furthermore, this body part 2a is provided with a screw hole inclined forwardly by approximately 45 DEG, which opens into a recess of the body part 2a and in particular accommodates a pressure screw 4 with a square hole.

Part 2 optionally comprises a second screw hole in its front part.

This screw hole is parallel to the first screw hole, passes through the tenon part 2b, and opens in front of the tenon part.

This second screw hole receives a pressure screw 5 for establishing a secure fixation if required.

The second member 3 has a shape suitable for partially entering the recess of the main body portion 2a of the first member 2 and sliding within this recess.

The second member 3 has a 45° inclined surface 3a on its front part, and the end of the pressure screw 4 is disposed opposite to this inclined surface.
The axis of the pressure screw 4 is approximately perpendicular to the plane of the inclined surface 3a. Furthermore, the member 3 is provided with a retractable pin 6 arranged in a slot transverse to its rear part.

In this embodiment, the member 3 branches at its rear into a beaded edge 3b carrying said pin 6 and a fruiting edge 3a with small groups.

The pin 6 slides at right angles to the bead 3b and is associated with a conical spring 7.

This spring 7 causes the pin 6 to protrude from the upper surface of the beaded edge 3b that is approximately at the same level as the upper surface of the first member 2.

In this embodiment, the small diameter end of the spring 7 is introduced into a hole in the pin 6, and the large diameter end of the spring 7 is anchored in a small group of fruiting edges 3c.

Furthermore, the pin 6 is provided with a stop flange 6a near its lower end to prevent it from coming off under the action of the spring 7.

The pin 6 also has a shoulder 6b, and the small diameter end defined by this shoulder enters and fits into the hole P of the profile T.

The remainder of the pin has a larger diameter than the diameter of the hole P so that it is fixed in the profile T at the level of this shoulder 6b.

Furthermore, elastic coupling means, such as a hollow rubber beat 8, are interposed between the first member 2 and the second member 3 at the front end of the recess in the main body 2a of the first member 2.

This beat member 8 can be anchored within a group of parts 3 and facilitates the installation operation by preventing accidental movement of parts 3 relative to parts 2 during installation of the present joint 1.

3a, 3b, 3c and 4 show the stages of the assembly process of the profile with the joint described above, and are intended to provide a better understanding of the function of the various means according to the invention.

In a first step (FIG. 3a), the tenon 2b is introduced into the group R of the profile M and is slid to the desired height.

The joint 1 is then introduced into the profile T from its rear by simply pushing the profile T parallel to the arrow F in FIG. 3a.

At the beginning of this introduction operation, pressure is applied to the pin 6 to cause it to retract and enter the mold member T.

Note that during this introduction, the width of the slots L1 and L2 should be smaller than the diameter of the pin 6, in order to prevent the pin 6 from fitting into the slots L1 and L2.

At the end of the introduction operation (FIG. 3b), the pin 6 reaches the level of the hole P and fits into it.

In this case, a gap J remains between the end face of the profile T and the corresponding surface of the profile M.

Inaccuracy in the position of the hole P does not impede the fabrication of the assembly;
It only affects the size of the play gap J.

In a second step (FIG. 3c), the pressure screw 4 is operated by means of a wrench through the slot.

The part 3 is pushed forward and moves this profile T via the pin 6 (which is in contact with the profile T in the hole P) until the end face of this profile T comes into contact with the corresponding surface of the profile M. .

Further screwing in of the pressure screw 4 then results in a mutual tightening of both types and a play-free fixing of the assembly.

It is also possible, but this is not necessary, to ensure a secure fixation by screwing the pressure screw 5 through the slot L2 in order to press its end into the bottom of the group R.

It will be appreciated that assembly of the joint according to the invention is quick and simple and does not require any special precautions.

Inaccuracies in the holes in the profile T do not impede the performance of the assembly operation and do not affect the resistance and quality of the assembly.
