Description

[Detailed Description of the Invention] The present invention relates to a lever device for operating a wire in a bed, a patient carrier, etc., in which the raising, lowering, inclination, etc. of the floor are controlled by operating the wire. .

The present invention will be described in detail below based on examples.

Reference numeral A denotes a member, and the member A is made of a spring material and integrally constitutes coil parts 1 and 2 at both ends which are concentrically arranged, and an intermediate coil part 3 which is eccentric in the lateral direction.

Reference numeral B indicates a wire operating lever device, and the lever device B has a grip portion 4 and an operating lever 6 rotatably provided on the side of the grip portion 4 about a fulcrum 5.

Reference numeral 7 is an operating wire.

One end coil portion 1 of the member A is then fixed to the grip portion 4 by an appropriate method, and the operating wire 7 is passed through the intermediate coil portion 3.

An end of the inner wire 8 of the operating wire 7 is connected to the operating lever 6, and the other end is connected to an element for controlling the elevation and inclination of the floor, such as a telescopic rod 13 described later.

For example, FIG. 2 shows an example of a bed in which the raising and lowering of the floor is controlled by operating the operating wire 7. In this figure, reference numeral 9 indicates a back floor plate which is tilted by rotating upward, and 10 indicates a back floor plate which can be rotated. a support arm movably supported on the base frame 11;
2 is an operating rod protruding from the lower side of the back floor plate 9; 13 is an extendable rod connected between the operating rod 12 and the base frame 11; the operating rod 14 can be made telescopic or non-extensible by operating an operating wire; It is a rod, and supports the back floor plate 9 from a tilted state to a horizontal state according to the expansion and contraction of the telescoping rod 13.

The telescopic rod 13 may be a so-called gas spring whose expansion and contraction can be controlled by utilizing the compressive elasticity of gas and the incompressibility of liquid, or a rod inserted inside the cylinder by the tightening force of a coil spring built into the cylinder. A telescopic locking device that disables the cylinder from expanding and contracting and allows the cylinder to expand and contract by releasing the tightening force, and a telescopic locking device that utilizes the principle of tilt locking can be applied.

In the above configuration, the wire operating lever device B of the present invention can be supported by fitting the end coil portion 2 into the fitting hole 15 formed in a suitable place such as a bed, for example, in the upper part of the base frame 11. , the operating lever 6 can be operated at an appropriate position when raising and lowering the floor.

However, in the lever device B of the present invention, since the operating wire 7, which has the inner wire 8 connected to the operating lever 6, is passed through the intermediate coil portion 3, bending of the operating wire 7 that is likely to occur in this portion can be effectively prevented. In addition, since the intermediate coil part 3 and the end coil part 2 that fit into the fitting hole 16 are eccentric in the lateral direction, the operating wire 7 can be prevented from coming loose in the end coil part. It has the characteristic that it does not interfere with the fitting of the parts 2 and 2.

Moreover, since the end coil portion 2 is made of a spring material, it can be elastically bent against an unreasonable load, and therefore, if a patient gets caught on the lever device when getting on or off the bed. However, the major feature is that it does not break and does not cause injury to patients.

The lever device of the present invention may be applied to other devices operated by operating wires, in addition to raising/lowering or tilting the floor of a bed or the like.
