CARRYING OUT THE INVENTION

FIG. 2 is a perspective view of a connector bracket in accordance with one preferred embodiment of the present invention.

In accordance with one of the preferred embodiments of the present invention, the connecting bracket 5 has a U-shape formed by two shelves 6, 7 connected to the wall 8.

The connecting bracket 5 can be made by bending a single piece of metal and have corresponding rounded parts at the bending points. An example of such a rounded portion is indicated by reference numeral 9 in FIG. 2. However, the present invention is not limited to the specified embodiment, and, if necessary, the connecting bracket can be made without rounded parts. In the connecting bracket 5 of the present invention, the flanges 6, 7 extend at a substantially 90 ° angle relative to the wall 8. In other embodiments of the present invention, the flanges 6, 7 may extend at any suitable angle relative to the wall 8, depending on the design requirements.

The shelves 6, 7 of the connecting bracket 5 have lateral 10, 11, 12, 13 and end edges 14, 15, 16, 17, and each of the shelves 6, 7 is connected to the wall 8 by one of its end edges 14, 16.

In accordance with one preferred embodiment of the present invention, the protrusion 18 extends from the side edge 10 of the shelf 6, and the protrusion 19 extends from the cross-lying side edge 12 of the shelf 7.

Despite the fact that in the specified one of the preferred embodiments of the present invention, one protrusion extends from the side edge of each of the shelves, in other embodiments of the present invention, the connecting bracket may have only one protrusion extending from the side edge of one of the shelves, or more protrusions extending from opposite and / or criss-crossing side edges of the shelves.

In accordance with various embodiments of the present invention, the projections may be integral with the flanges in the connecting bracket and are essentially folds made by folding a single piece of metal. In particular, the flat projections can be formed by stamping.

If necessary, the projections 18, 19 can be folded away from part of the side edge or from the entire side edge.

Although FIG. 2-6 projections 18, 19 are shown having a square planar shape, the present invention is not limited to this embodiment. Thus, the projections can be of any other suitable shape and size, if necessary.

In accordance with one preferred embodiment of the present invention, the projection 18 includes an opening 20. The projection 19 is also provided with a single opening (not shown).

The holes of the protrusions 18, 19 are designed to connect the connecting bracket 5 to an object, for example channels 2, 2 *, containing the corresponding holes. The hole can be made at any suitable location on the protrusion. If necessary, the projections 18, 19 can contain more holes.

FIG. 2 and a top view of the connecting bracket of FIG. 3 shows that the projections 18, 19 extend at a substantially 90 ° angle relative to the shelves 6, 7. If desired, the projections can extend at any suitable angle relative to the shelves, depending on the design requirements.

As shown in FIG. 3, the projections 18, 19 extend outwardly from the shelves 6, 7.

FIG. 4 shows the use of a connecting bracket for attaching channels 2, 2 * to a profile pipe 4.

The present invention is not limited to the specified application of the connecting bracket, which, if necessary, can be used to connect any suitable object having a hole to the profile pipe. In addition, the dimensions and other characteristics of the profile pipe, channels, connecting brackets can be selected by a person skilled in the art, depending on the range used.

To attach an object, for example U-shaped channels 2, 2 *, consisting of two flanges connected by a wall and containing holes 21 in the wall, as shown in FIG. 4, using the connecting bracket 5, is carried out by means of a method comprising the following steps:

- ensure the presence of a connecting bracket 5;

- put the connecting bracket 5 on the profile pipe 4, ensuring that the bracket 5 adheres to the pipe 4;

- align the hole 20 of the protrusion 18 of the connecting bracket 5 and the hole of the object (channel 2), as well as the hole of the protrusion 19 of the connecting bracket 5 and the corresponding hole (not shown) of the other channel 2 * located opposite to the channel 2;

- bolts 3 are inserted through the hole 20 of the projection 18 of the bracket 5 and the corresponding hole of the channel 2, as well as through the hole of the protrusion 19 of the bracket 5 and the corresponding hole of the opposite channel 2 * and screw nuts on the bolts 3.

If necessary, before the stage of introducing bolts 3, a washer is put on the corresponding bolt and a second washer is put on the bolt from the opposite side before screwing the nut onto the bolt.

In accordance with one of the preferred embodiments of the present invention, as a result of performing the steps of this method, the connecting bracket 8 encloses the profile pipe 4, and the protrusions 18, 19 are rigidly connected to the channels 2, 2 * by bolted connections.

FIG. 5 shows a perspective view of a connecting bracket 5 * in accordance with another preferred embodiment of the present invention.

All of the above design variants apply to the 5 * shackle, subject to the following differences.

In the connecting bracket 5 * curved legs extend from the end edges 15, 17. These curved legs extend from the respective end edges 15, 17 towards each other and are further curved away from the wall 8. As shown in FIG. 5, the curved legs are composed of walls 22, 23 substantially parallel to wall 8 and flanges 24, 25 substantially parallel to flanges 6, 7.

FIG. 5 shows that the walls 22, 23 can be rounded. However, the present invention is not limited to this embodiment.

Preferably, the curved legs are made of a single piece of sheet metal in one piece with each other and with the rest of the connecting bracket. However, if necessary, the walls 22, 23 and the legs 24, 25 can be made separately from each other and connected to each other in any suitable way.

The size of the shelves 24, 25 and the walls 22, 23 of the legs is selected so that when the connecting bracket 5 * is put on the profile pipe 4, the pipe is squeezed by the bracket.

The legs 24, 25 can each have one hole 26, 27, preferably, but not limited to, in the central part of the leg.

The holes 26, 27 are intended to receive the pin 28 shown in FIG. 6.

To attach an object, for example U-shaped channels 2, 2 *, consisting of two flanges connected by a wall and containing holes 21 in the wall, as shown in FIG. 4, using the connecting bracket 5 *, a method is carried out including the following steps:

- ensure the presence of a connecting bracket 5 *;

- put the connecting bracket 5 * on the profile pipe 4;

- crimp the connecting bracket 5 * on the profile pipe 4 ensuring that the bracket 5 * adheres to the pipe 4 and aligns the holes of the protrusions 18, 19 of the connecting bracket 5 * and the holes of the object (channels 2, 2 *), as well as aligning the holes 26, 27 of the legs each relative to a friend;

- bolts 3 are inserted through the holes of the projections 18, 19 of the brackets 5 * and the corresponding holes of the channels, and nuts are screwed onto the bolts 3;

- insert the pin 28 through the holes 26, 27 of the legs and screw on the nuts 3 * from the opposite ends of the pin 28.

If necessary, instead of the pin 28, a bolt can be inserted through the holes 26, 27 of the legs, followed by screwing a nut onto it.

In some embodiments of the invention, before the step of inserting the bolt through the hole of the bracket protrusion and the corresponding hole of the object, a washer is put on the bolt and a second washer is put on the opposite side before screwing the nut onto the bolt, or at least one washer is put on the stud 28 before the nut is screwed onto it.

Although FIG. 6 shows the adjoining of the ends of the hairpin to the channels 2, 2 *, the present invention provides for the possibility of placing the hairpin between the channels 2, 2 * without adhering to their surfaces.

If necessary, the legs 24, 25 can contain more holes for bolts, pins and other additional connectors to pass through them.

In the presence of a larger number of protrusions extending from the side walls of the bracket shelves, it is necessary to ensure the alignment of the corresponding holes of the protrusions and holes of channels or other objects, as well as to carry out their bolted or other connection.

When making any protrusion without holes, it is necessary to ensure the abutment of such a protrusion to the object and / or, if necessary, its attachment by any suitable means.

It should be noted that the described connecting bracket and the method of attaching the object containing the hole to the shaped pipe are only some of the preferred embodiments of the present invention. It will be apparent to a person skilled in the art that changes and modifications can be made to the present invention without departing from the scope of the invention as defined by the claims below.
