Description

Explanation of the essence of the invention

The invention has for its object to increase the axial adjustment of the cable deflection, to allow any angular positions of the cable deflection and to reduce the length of the horizontally arranged pipe section. According to the invention, this object is achieved in that the two ends of the horizontally arranged pipe section are open and another Seilumlunkung with a pipe in the horizontally arranged pipe section either right Jder is inserted and lockable left. In the tube of this further rope deflection a threaded spindle with a star grip and a pressure piece and a longitudinally displaceable cone is mounted with internal thread. The tube has slots on the side of the cone seat. The main body of the cable deflection on the horizontally arranged pipe section has a slot and can be clamped by means of a clamping knob on the horizontally arranged pipe section. Preferably, the connections between the vertically arranged tube legs and the horizontally disordered tube piece clamping connections. The solution according to the invention has the advantage that a considerably larger axial adjustment range is achieved by the further cable deflection. When driving through doors, the further cable deflection can be inserted or temporarily removed. In the latter case, the width of the extension device corresponds to the bed width. Due to the clampable attachment of the two cable deflectors, the axial adjustment is infinitely possible. The angular position of the cable deflections is arbitrary. By Wegfa 'the arcuate transitions between the vertically arranged pipe legs and the horizontally disposed pipe section an extension of the guide pipe pieces at the bedside is possible, so that the height adjustment of the extension device can be increased. Finally, more favorable production conditions result for the solution according to the invention by eliminating the pipe curvatures.

The invention is explained in more detail below with reference to an exemplary embodiment. In the accompanying drawing show:

2: another cable deflection with a pipe in a sectional view.

At the ends of the frame longitudinal parts 1 and 2 of the hospital bed two pipe sections 3 and 4 are arranged vertically fixed. In these, the Flohrschenkel 5 and 6 are feasible. The pipe legs 5 and 6 have transverse bores 7, in which locking elements 8 and 9 engage. The tube legs 5 and 6 are height adjustable in stages. On the tube legs 5 and 6 clamping parts 10 and 11 are arranged, which carry bores in which a horizontally arranged pipe section 12 is receivable and clamped. On dom pipe section 12 is a Seilumlenkun? 13 slidably, pivotally mounted and clamped. The cable guide 13 has a base body 14 groove 14 a slot 15, a tensioning knob 16, a roller holder 17 and a pulley 18. In the pipe section 12, a further cable deflection 19 with a tube 20 is inserted (Fig. 2). Inside the tube there is a threaded spindle 21 and an axially displaceable cone 22. The tube 20 has longitudinal slots 23. On the threaded spindle 21, a pressure piece 24 is attached. To rotate the threaded spindle a star grip 25 is mounted on this. On the tube 20, a base body 26 is fixed, on which a roller holder 27 is rotatably arranged. This carries a bolt 28 with a pulley 29. The cable guide 19 can be used either left or right in the pipe section 12 warden. By turning the star grip 25, the cone 22 is displaced axially, whereby the tube 20 is spread, resulting in the clamping in the pipe section 12. The cable guide 19 can be adjusted and fixed steplessly in the axial direction. In addition, any angular positions of the cable deflection can be adjusted. Likewise, the cable guide 13 is axially freely displaceable and pivotable, so that any angular positions are adjustable.

For this 1 page drawings Field of application of the invention The invention relates to a hospital bed with an extension device for the treatment of fractures of the lower limbs. To heal such fractures, it is necessary to exert a permanent tensile force on the lower fragment of the bone in order to prevent a bone displacement at the fracture site or to achieve a favorable setting of the bone fragments. For this purpose, the thigh or lower leg bone is provided with a transverse bore, after which a bracket is fastened by means of an inserted into the bore in the bone tensioning wire. In this bracket the pull rope of an extension device can be suspended. The leg is stored on a corresponding rail. The extension device is part of the hospital bed. Characteristic of the known state of the art In the patent application WP A 61 G / 301935 a hospital bed with an extension device has already been proposed. This extension device consists essentially of a horizontally arranged pipe section with two vertically pointing down tube legs, which are in two attached to the foot of the hospital bed vertically arranged pipe sections, feasible. The horizontally arranged pipe section has a plurality of transverse bores, with the aid of such a cable deflection by means of a securing element in different settings can be locked. For the purpose of height adjustability of the cable deflection, the vertically arranged pipe legs also have a plurality of transverse bores in which securing elements can be inserted or screwed. The transitions from the horizontally arranged pipe section to the vertically arranged pipe legs are arcuate. In order to achieve the largest possible adjustment range in the horizontal direction, the straight part of the horizontally arranged pipe section is larger than the distance of the vertically arranged pipe legs, so that the pipe bends protrude considerably over the bed width. The extension device therefore has a width which does not allow passage through doors in some cases. However, it is necessary to drive through doors as the patients have to be driven to the X-ray department in their illnesses. Another disadvantage is that a considerable part of the guide length is lost through the arcuate transitions from the horizontally arranged tube piece to the vertically arranged tube legs, so that the height adjustment range is limited. The preparation of the arcuate transitions is complicated, since they must be so accurate that the distance between the vertically arranged pipe sections is maintained exactly. By fixing the cable deflection by means of a securing element in the transverse bores of the horizontally arranged pipe section, the angular position of the cable deflection is fixed. The axial displacement is possible only in stages. Object of the invention The aim of the invention is to increase the axial adjustment and the height adjustment of the cable deflection, thereby reducing the overall width of the extension device, to ensure an attachment of the cable deflection stepless and in different angular positions and to simplify the production of the extension device.
