Abstract

The invention concerns an assembling device in particular for mutually connecting together two bars, which have at an assembly point two substantially complementary profiled sections, one positive and one negative. Said profiled sections are set in assembling position along a parting line, taking into account a given degree of freedom, a separate safety block extending on either side of the parting line between the positive profiled section and the negative profiled section. The bars associatedwith the safety lock form an assembly consisting of three elements, between which a mobility locking is formed by the safety lock in the direction opposite to the direction of the degree of freedom, immediately prior to assembly positioning. When the assembly is carried out, the lines of the positive and negative profiled sections form a recess corresponding to a transverse profiled section of the safety lock, said recess being covered on both sides by the parting line.

Description

The present invention relates to a coupling device (1) between two coupled rods (2, 3) which, at the coupling point (4), have substantially complementary positive and negative profiles which are brought to a coupling position along the separation joint (7) with a degree of freedom. , it has a separate closure latch (9) extending on both sides of the joint (22) between the positive and negative profiles, the rods (2, 3) together with the closure latch (9) forming a joint between three components, between which in the opposite direction of the degree of freedom (X) the movable barrier is formed by the closing latch (9) and the connected positive (5) and negative (6) profiles form a recess (8) corresponding to the cross-section of the closing latch (9). ) from both sides.

The invention relates to a joining device, namely a joining device between two joining rods, which at the joining site have substantially complementary positive and negative profiles which are brought along the joint at a certain degree of freedom.

Connecting devices of this kind are known in principle. They are described, for example, in European Patent Application EP0399371 and French Patent Application FR2784721. This is commonly referred to as groove-to-tie joints when the joining bars are pushed in this area. This joint has yet to be secured by simple application of glue, welding or riveting.

Thus, at least one tool is needed to make the joint, which increases the cost of producing these joints. In addition, in the case of special joints, such as groove-to-tie joints, the final user is completely prevented from doing so. Therefore, the connection must be completed at the manufacturing site. This results in high transport costs for extra bulky rod structures.

It is an object of the invention to provide a connection device of the kind mentioned above, which, thanks to technically simple means, always guarantees a strong and stable connection and at the same time can be connected without any aids.

According to the invention, this object is achieved by the use of a separate closure latch extending across the joint between the positive and negative sections of the jointing device, while the bars together with the closure latch form a joint of three components with in the direction of degree, the closing latch creates a movable barrier, and the combined positive and negative profiles form an opening corresponding to the cross-section of the closing latch, which overlaps the joint on both sides.

The device according to the invention is very easy to use since it is only necessary to combine the positive and negative profiles in the defined direction of connection. Once the bar profiles are connected, you only need to insert the appropriate locking latch into the existing slot. This job is very simple and requires no tools.

First, a combination of positive and negative profiles results in geometric closure. Only the insertion or insertion of the closing latch results in force closure.

According to another embodiment of the invention, it is provided that the positive and negative profiles mutually include at least one first end notch. The shape given to the profiles alone provides some support.

However, it is also possible for the closing latch to engage with the second rear notch when engaged. This positioning of the locking latch prevents both rods from loosening in the longitudinal axis of the rod.

Particularly robust jointing will occur when both positive and negative profiles and the locking latch are joined to the third end notch.

It is sufficient that the longitudinal axis of the closing latch extends perpendicular to the degree of freedom to prevent movement in the direction of the last degree of freedom before final assembly. This results in a very tight joint under tensile load along the longitudinal axis of the rod.

The joint can be completely disassembled by reciprocating displacement perpendicular to the longitudinal axis of the rod. To avoid this, it is useful that the longitudinal axis of the closing latch is inclined in the direction of the degree of freedom. The closing latch can be fitted with a screw.

The joints mentioned so far have involved joint joints along the longitudinal axis of the joining bars. However, it is also possible for the bars to be connected to each other at a blunt, right or pointed angle.

In another embodiment, at least four bars are provided to be joined in one frame. Due to this typically built-in connection, these four rods can be transported after disassembly to save space and costs.

This is especially true when the frames are large. Certain applications require frames with lengths up to about 7 m. Since the short sections meanwhile are about 3.50 m, transporting the finished frame would require more space and cost. This transport area can now be reduced by the present invention, as individual parts of the frame can be transported stacked on top of each other.

At the destination, these frame parts are folded accordingly and the corresponding locking latch is pushed in each corner.

The locking catch retracted there can be removable or non-removable. However, this also applies to all connections mentioned so far.

According to another embodiment of the invention, the cross-section of the closure latch is provided to be rectangular, circular, rhombic, octagonal, swallow-tail, elliptical or cross-shaped.

When the connecting rods are light in weight but high in strength, it is useful when the rods are hollow and confined to the reinforcements at the joints.

Particularly useful are the reinforcements which are hollow and solid bars adapted to the bar cavity and which touch the inner surface of the rods in a full plane or along at least two lines in length, while the reinforcement is mounted either along the entire length of the rod or along part of the entire rod.

Typically, positive and negative profiles are produced by different shape-forming tools so that they are substantially complementary in the joint position. Low-cost production is particularly useful, as well as storage, when the positive and negative profiles are connected in a cross-section symmetrical to the center. Therefore, all profiles of this kind can be produced with the same mold tool.

Stacked on top of each other, the bars have an identical profile. In order to push these positive and negative profiles into one another, it is only necessary to rotate one bar lying on the other bar at an angle of 180 ° and inserted into the appropriate profile.

Useful when the structural parts are metal, wood or plastic, or a combination of at least two types of material.

It goes without saying that other materials may be used.

Other positive features / features of the invention emanate from the following description of many embodiments, as well as from the accompanying drawings, in which:

Figures 1 a, b, - 15a, b are views of the front sides of the bars as well as of the jointing devices according to embodiments 1-15.

According to FIG. 1a, b to 15a, b illustrate fifteen embodiments, noting that there are many other options for constructing this connection device.

For clarity, despite different profiling, the same output drawing is used for all execution examples.

The drawings show the connecting devices 1 which are used between the two first and second connected rods 2 and 3.

These rods 2, 3 are joined by a joining site 4. In addition, the rods 2 and 3 have two substantially complementary positive 5 and negative 6 profiles, which are aligned along the separation seam with a degree of freedom X into the joint position. This degree of freedom X represents the final direction of motion for achieving geometric closure between positive 5 and negative 6 profiles. Although only one direction of the arrow of degree of freedom X is always used in the drawings, it goes without saying that the opposite direction can also be used to perform the joining. This degree of freedom X can be in the form of a straight line as shown in the drawings or, for example, in the form of a circle or a curve.

In the description according to the drawings, it is assumed that the first rod 2 is immobile and the second rod 3 is movable by joining the first rod 2.

When both of these rods 2 and 3 are folded into the joining position, a separate closing latch 9 is inserted into the recess 8.

This recess 8 is formed in the joined position of the positive profile 5 and the negative profile 6 and corresponds to the cross-section of the closing latch 9.

A separate closing latch 9 extends on either side of the joint 7 between the positive 5 and negative 6 profiles. The rods 2 and 3 together with the locking latch 9 form a joint of three components, between which a movable barrier is formed by the closing latch 9 directly before reaching the position of engagement in the opposite direction to the connecting position.

When the two rods 2 and 3 are joined together, the geometric closure first occurs. Only when the locking catch 9 is inserted or inserted is the force locked.

There are three options for performing these geometric and force closures. On the one hand, the positive 5 and negative 6 profiles may be so profiled that they mutually include at least one first end cut-out 10. This is illustrated in Figures 8, 9, 11, 14 and 15.

Another possibility exists when the locking latch 9 engages with the second rear cut-out 11 in its engaged position. Such end cut-outs are shown in FIG. 1-5, 7 and 10.

Finally, there is another option: a combination of both rear notches. This occurs when both the positive 5 and negative 6 profiles as well as the closure latch engage with the third end notch 12. This is illustrated in Figures 6, 12 and 13.

For the direction of the closing latch 9, there is a possibility that the longitudinal axis of the closing latch 9 extends perpendicular to the X direction of the degree of freedom. This is perpendicular to the plane of the drawing sheet in FIG. 1-15.

Of course, there is still the possibility that the three components of the joining device 1 are still moving perpendicular to the plane of the sheet and thus loosening / loosening.

If this is not desired, this is prevented when the longitudinal axis of the locking latch 9 runs obliquely in the X direction. The closing latch 9 therefore passes inclined to the normal plane of the sheet.

Therefore, in the first case the closing latch runs diagonally on one axis, whereas in the second case it runs diagonally on two axes.

To date, the joints of rods 2 and 3 have been described where the longitudinal axes of rods 2 and 3 overlap. However, it is also possible for the bars to be connected to each other at a blunt, right or pointed angle.

In most cases, however, there will be a status angle so that a rectangular frame can be constructed from the bars 2 and 3 and the coupling device 1.

This is especially useful when the frame is large. For example, there are frames with a side length of 7 to 3.5 m. Until now, it has been customary to transport frames of this size once assembled or assembled at destination using an appropriate tool such as a welding machine.

This type of frame can now be transported disassembled, saving on transportation costs. Compared to the previous version, small packages are now being transported. At the destination, appropriate rods 2 and 3 are mounted such that positive 5 and negative 6 profiles join with each other. Finally, all you need to do is insert a locking latch 9 into each corner. Of course, other indoor units and structures can be installed.

These fitted latches 9 can be either unscrewed and retracted 6. However, it is also possible to attach this closure latch 9 by appropriate means.

The cross-sectional shape of the closure latch 9 may take various forms. Thus, the closure latch 9 in the cross-section may, for example, be rectangular (Figs. 1, 5, 6,

8, 9, 14 and 15), circular (fig. 10-12), rhombic (fig. 13), octagonal (fig. 4), swallow-tail (fig. 7), elliptical or cross-shaped (fig. .2 and 3).

If, for reasons of weight loss, the rods 2, 3 are hollow, the joints, and in particular the rods 2, 3, nevertheless have a certain rigidity, reinforcements adjacent to, for example, the joints of the rods 2, 3 can be envisaged.

It is possible that the reinforcements are hollow and solid bars adapted to the inner cavity of the rods 2 and 3. The cross-sectional shape of the adapted hollow and solid bars may be selected so that they touch the inner surface of the bars 2 and 3 in the full plane or along at least two lines, while the reinforcement is provided either along the entire length of the bar or . This results in extremely high torsional and bending resistance for the large frames mentioned above.

A common feature of all embodiments is that the positive 5 and negative 6 profiles, when connected, are symmetrical to the center in cross section.

This means that the two profiles are stacked identically.

This reduces production and storage costs. However, asymmetrical profiling can also be envisaged.

Different types of materials can be used, but metal, wood, or plastic, or a combination of at least two types of materials, is preferred.
