Angle bracket

1. The invention relates to a bracket holder for connecting two struts extending at an angle to each other, preferably for use in furniture.

The angle bracket according to the invention consists of the actual angle element, a connecting plate and a cover plate. The angle element has two projections which are at an angle to one another and which are adapted to the required angle of the struts to be connected, one projection being connected to the one of the struts and the other projection to the second strut. The first strut is such connected to the angle bracket, that they angle holder to a projection of the angular element is inserted with a pin in '~, wherein the pin is adapted ment in its shape and in its dimensions of the corresponding recess in the Winkelele- ^J. The connection of the second strut to the other projection of the angle element of the angle bracket is carried out by means of a screw which passes through the second projection of the angle bracket, but is sunk into it, and is screwed to the second strut in a manner known per se.

As far as the first strut with the mentioned pin is inserted into the angle element of the angle holder, the angle element has at least one transverse to the direction of the recess in the first Protrusion of the angle element and to the direction of the inserted %

Pin of the first strut extending hole. In this hole at least one pin engages on the mentioned Connection plate is attached. The connecting plate is in turn designed so that it is in the angle element of the angle bracket used, can be placed at least in dimensional coordination. The connecting plate has furthermore, on the same side as the aforementioned pin, a hole in the dimension and position of the other Bore of the angle element is adapted, said screw for connecting the angle bracket through both holes is passed through with the second strut.

If the connecting plate is inserted into the angle element, the pin attached to it penetrates through the hole of the angle bracket into the first strut inserted therein with a prepared hole and blocks it in pulling and rotating directions.

After inserting the screw in the angle element and screwing with the second strut the adapted cover plate is wixrd inserted or placed on the outer side of the angle bracket opposite the connecting plate.

The cover plate expediently has the angle element on its facing side also at least one pin which engages in the bore of the angle bracket and after Assemble in the pin of the first strut in addition to penetrating the pin of the connecting plate.

If the angle bracket is used with a second strut with a larger diameter, it is on the connecting plate of the angle bracket on the side facing away from the angle element and facing the second strut additional pin attached, which is in a corresponding hole or other recess of the second strut in the

Connection with the angle bracket is introduced and gives an additional hold against tensile and / or torsional forces.

Due to the symmetrical design of the for receiving the connecting plate or the cover plate certain sides of the angle element and dimensional congruence of the connecting plate and cover plate, the connecting plate and the cover plate can be used on either side of the angle element or placed on, so that the second strut using the same angle bracket on both sides can be set.

2. Angle brackets for connecting two struts are available in different Embodiment known, in particular from the Furniture making. Unless the two struts, such as with wooden struts, by means of mortise or tenons / Slot combinations are connected, become connection angles made of metal, wood or plastic. These will either be on the two struts to be joined placed and screwed with screws that are guided through the angle plates, or the angle brackets are used in corresponding recesses of the two struts. In both cases these angle brackets have the main one Disadvantage that they are only suitable for one-sided connection of the struts, i.e. each separately Angle brackets are required if the second strut are hinged to the right or left of the first strut target. In addition, the known angle brackets have significant disadvantages from an aesthetic point of view, since the fastening is generally visible and thus the overall design is essential, especially in the case of pieces of furniture impaired. If this is to be avoided, additional cladding or covers are required with a correspondingly greater amount of work and costs.
