A table for universal deposition of dental tools, is disclosed including a receiving part (3) the outer limitation of which contains at least over a portion of its perimeter a rim (4) with a rim end portion (4b) extending downward in relation to the deposit surface (5) of the receiving part (3). The receiving part (3) is adapted to be attached to a mount (9) comprises a carrier (9) with a horizontal bearing surface (10) for the receiving part (3). A depression (11) is located in the carrier (9) and adapted to receive the rim end portion (4b) of the receiving part (3) to provide a mechanically locking engagement. The mount also includes a projection (12) which is arranged at a distance from the depression (11) corresponding to the rim height of the receiving part (3) and which extends at least partially over the upper surface (6) of the rim (4) when the receiving part (3) is placed on the carrier (9).

Table for dental tools

The present invention is directed to a bracket structure which has one or more tubular members interconnected by elbow members. At least one of the tubular members is connected to an elbow member by a plug-type connection having a socket receiving a pin part with the socket and pin part being constructed so that no twisting will occur between the two parts in the assembled position but the two parts can be disassembled and reassembled with the position of the parts being rotated through at least 180.degree. relative to each other. This provides the advantage of enabling easy changing of the bracket from being adapted for a floor mounting to a ceiling mounting.

Bracket structure for dental purposes

A parallelogram bracket assembly with a force balance mechanism which utilizes a pneumatic spring situated in the parallelogram bracket assembly. The pneumatic spring has a cylinder receiving a piston which has a piston rod and the cylinder is supported against parts connected to one articulated axle and an end of the piston rod is supported against parts which are connected to an articulated axle diametrically arranged to the one articulated axle. According to the invention, one of the rod members forming the parallelogram bracket assembly has a tubular guide channel for the telescopic acceptance of the pneumatic spring in a manner to allow an easy interchangeable fashion. For easy replacement of the pneumatic spring, an end piece is connected to the articulated axle and is releasably held at least at one end of the guide channel and the piston rod or the cylinder presses against this end piece.
