Definitions

• the invention relates to a tripod system according to the preamble of claim 1.
• tripods are used in particular as ceiling tripods for intensive care units, operating theaters and others. used.
• a carrier for the pivotable suspension of control devices is known.
• a joint half is formed by a housing which is pushed onto an arm designed as a connecting tube and secured there by means of a grub screw.
• a tripod is known from DE-OS 30 34 013, the arms of which are formed separately from the joint halves. The connection is made by screwing the arms onto the joint.
• the object of the invention is to provide a tripod system of the type described at the outset, which is designed in such a way that a particularly simple and at the same time particularly effective connection between the arms and the joint is made possible with a simple design of the joints.
• the figure shows a section through a tripod system.
• the stand system comprises a first joint with a joint half 1 which can be connected to a ceiling, for example, and a second joint half 2 connected to this, a joint 4 connected to the second joint half 2 via a first arm 3 and a second joint connected to the joint 4 Arm 5 and a joint 6 connected to the second arm 5.
• the joint 4 comprises a first joint half 7 and a second joint half 8.
• the first joint half comprises a shell-shaped part 9 with an inner cylindrical section.
• the second joint half 8 has an annular extension 10 which engages in the cylindrical section of the shell-shaped part and forms the actual bearing with the latter.
• the annular extension 10 is supported in the form of a bearing in the shell-shaped part via a wire roller bearing 11.
• the shell-shaped part has on its cylindrical inner surface a rectangular recess 12 which extends in the circumferential direction.
• the annular extension has a corresponding rectangular recess 13 extending in the circumferential direction on its outer surface.
• the annular extension 10 has a first annular section 14 and a second annular section 15.
• the two sections are detachably connected to one another by means of screws.
• the parting plane between the two sections 14 and 15 is placed so that it passes through the bottom of the recess 13.
• the second ring-shaped section 15 can first be unscrewed and removed, which makes it possible to use the wire rings and balls with associated spacers. Then the ring-shaped section 15 is placed in the manner shown in the figure and firmly connected to the first ring-shaped section 14 by screws.
• a brake device 19 is provided in the first joint half 7 and is firmly connected to the shell-shaped part 9.
• the brake device has a diaphragm-actuated brake disk which is controlled by a fluid and which interacts with the brake ring 18 to brake the rotary movement of the two joint halves or to lock them together.
• each joint half 7, 8 has an extension 20, 21 extending in the direction of the arm 3, 5 to be connected to it.
• the arms 3, 5 are tubular.
• the lugs 20, 21 have an outer shape and size, which corresponds to the shape and size of the inner cavity of the tubular arms in such a way that the respective tubular arm 3, 5 to be connected to it in the manner of a plug-in connection to the neck 20, 21 can be pushed over the entire length of the attachment if possible.
• the length of the neck and of the part receiving the pipe is selected so that that there is a sufficiently rigid connection between arm and neck.
• Each approach has a recess 22 on its top
• a terminal strip 26, 27 is inserted into the respective recess.
• the terminal strip viewed in the direction of insertion, has threaded bores at a distance from one another which are congruent with holes in the attached arm.
• threaded holes 28, 29 are screwed into the terminal block through the holes in such a way that the terminal block is pressed against the inner wall of the arm 3 and the threaded pins engage the base of the recess .
• the set screws are so long that they still extend into the holes in the arm. This creates a lock against shifting the arm against the shoulder.
• the setscrews are tightened in such a way that they bring about a clamping connection between the tubular arm 3 and the attachment used inside. The force is transferred from the screws to the arm wall via the terminal strips.
• the individual joints are each provided with the same internal structure.
• the individual joint halves to be connected with arms each have the same approaches.
• the pipes to be attached are of identical design at both ends.
• the approaches of the respective joint halves and the joint halves themselves are also hollow, so that supply lines from the ceiling are located in the resulting entire cavity can be guided through the tripod to the device to be carried.
• the first half of the joint has a stop 30 which interacts with the stop rings to limit the rotational movement.
• the respective plug connection between arm and extension is formed in that the extension is pushed into the interior of the tubular arm.
• the internal dimensions of the hollow extension 20, 21 are dimensioned such that they can be pushed onto the respective arms to be connected to them in the manner described above.
• the recesses 22, 23 are then to be provided accordingly in the wall of the arm 3, and the terminal strips are screwed to the lugs 20, 21.
• the tripod in its desired shape by any combination of arms of different lengths or different shapes and respective joints provided between them.
