Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a lifting operation switch for raising and tilting the floor plate support frame of a bed in a hospital or the like and returning it horizontally, and particularly ON / OFF of the switch. The present invention relates to a bed raising / lowering operation switch that is extremely easy to operate.

[Conventional technology]

Conventionally, push button type switches, lever type switches and the like have been known as operation switches of this type.

In the case of a push-button switch, separate the lifting switch and the lowering switch separately at any position on the bed, hold the lifting switch while lifting the bed, and Operate by holding down the lowering switch.

Further, in the case of a lever type switch, this is fixed to an arbitrary portion of the bed as described above, and when the bed is lifted or lowered, it is operated by moving the levers in opposite directions.

[Problems to be solved by the invention]

However, the above-mentioned push-button type or lever-type switches are both cumbersome to operate, and particularly when operated by a sick person on a bed, those that are easier to operate are required.

Therefore, an object of the present invention is to provide a bed elevating and lowering operation switch in which ON / OFF operation of the switch and lifting and lowering operations are extremely easy and the drawbacks of the above-mentioned known art are improved.

[Means for solving problems]

In order to achieve the above-mentioned object, according to the present invention, a mounting table rotatably mounted on a bed via a rotating rod and a switch mechanism mounted on the mounting table are provided. The main body with built-in bed raising operation switch and return operation switch, and one end located in the gap between the two switches inside the main body, and the other end located outside the main body, and centering on the bearing point. Operation shaft supported by the main body so as to be swingable, and a spring wound around the operation shaft for returning the swing, and an operation fixed to one outer end of the operation shaft. And a piece.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

FIG. 1 is a perspective view of a specific example of the operation switch according to the present invention, which is constructed by mounting a switch mechanism 2 on a mounting table 1. In this mounting, the magnet plate 3 is attached to the mounting table 1, and a magnet plate is also attached to the bottom surface of the switch mechanism 2 (not shown), and the switch mechanism 2 is mounted on the mounting table 1 by these magnetic forces. You may fix it.

The mounting table 1 is connected to a rotary rod 4 and is rotatably attached to the bed 5 via the rotary rod 4 as shown in, for example, FIGS. More specifically, as shown in FIGS. 5 and 6, a cap nut-shaped receiving metal fitting 7 is fixed to the inside of the side frame 6 of the bed 5, and the tip 4a of the rotary rod 4 is fixed to the receiving metal fitting 7. By being inserted, it is rotatably attached to the bed 5 as indicated by an arrow.

Furthermore, as shown in FIGS. 7 and 8,
The rotary rod 4 may be attached to the side shelf 9 fixed by inserting the leg portions 8 on the upper surface 6a of the side frame 6 of the bed 5. You may install this. As shown in FIGS. 7 and 8, this mounting is performed by arranging two S-shaped stoppers 10, 10 in a vertical relationship, and arranging them in the same direction as the groove 1 opened in the same direction.
By fitting the legs 8 and the rotating rod 4 into the grooves 1 and 11 and the grooves 12 and 12, respectively, they are rotatably attached to the bed 5.

2 and 3 show the switch mechanism 2 in FIG.
2A is a cross-sectional view taken along line AA and FIG. The switch mechanism 2 will be described with reference to FIGS. 2 and 3.
The structure 13 is a main body, and the bed raising operation switch 14 and the bed returning operation switch 15 face each other in the main body 13 and are installed at a predetermined interval.

Further, an operating shaft 16 is supported on the main body 13.
The shaft 16 has one end 17 located in the gap between the switches 14 and 15 built in the main body 13 and the other end 18 at the main body 13
It is installed so that it is located outside of. Further, a receiving seat 19 is arranged inside the main body 13, and a stop ring 20 is fitted at a desired position of the operation shaft 16, and the stop ring 20 is attached.
By placing 20 on the receiving seat 19, the operating shaft 16
Is supported by the main body 13. With such a bearing, the operating shaft 16 can swing about a bearing point 21.

Further, a spring 23 is wound around the operation shaft below the stop ring 20, and the swing is returned by the spring of the spring 23.

Further, the operation piece 22 is fixed to the outer end 18 of the operation shaft 16 to form the operation shaft of the present invention. Reference numeral 24 is an arrangement plate for both switches.

[Action]

As shown in FIG. 4, the above-mentioned switch of the present invention causes the operating shaft 16 to be swung about the support point 21 by lightly touching the operating piece 22 with one hand so that one end 17 of the switch, for example, is operated. Press. At this time, the operation switch 14 is turned on, and the bed 5 rises, for example, as shown in FIG. At this time, since the mounting table 1 on which the switch mechanism 2 is mounted is rotatably attached to the bed 5 via the rotary rod 4, the mounting table 1 is rotated as the bed 5 rises, and the bed 5 does not interfere even when the bed 5 rises. .

On the other hand, when returning the bed, the operation piece 16 is lightly pushed in the opposite direction, so that the operation shaft 16 is swung in the opposite direction to press the other switch 15 facing the operation piece, and the return operation switch 15 is activated. Then the bed returns to the original horizontal position.

In addition, when the hand is released from the operation piece 22, the operation of the spring 23 causes
The oscillation of the operating shaft 16 returns to its original state, and the neutral O
The state becomes FF.

[Effect of device]

As described above, in the switch of the present invention, the operating shaft 16 swings around the support point 21 to turn the switch on by simply touching the operating piece 22 by hand, and the switch is turned off when the switch is released. Is extremely easy to turn on and off, and is particularly suitable as an operation switch for a hospital bed.
