DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an operation of an electric bed in which an operation switch for adjusting the inclination of a floor or raising and lowering is mounted on a side fence and can be removed and operated when used. The present invention relates to a switch mounting structure.

[0002]

2. Description of the Related Art In recent years, the number of motorized beds 1 has increased. However, this motorized bed 1 can be operated by operating an operation switch 3 provided on a pillow of a floor portion 2 which can be accessed by a user. It is configured to adjust the inclination and height of the section 2 (see FIG. 6). Some electric beds 4 have a structure in which an operation switch 6 is fixed to a side fence 5 attached to the bottom (see FIG. 7). In any case, most of the operation switches in the electric bed employ a control box with a built-in controller and a method of exchanging signals via an operation switch cord (wired method).

[0003]

However, in the former hand switch type, the operation switch cord sometimes gets in the way. On the other hand, the latter method is inconvenient because it can be operated only within the reach of the operation switch 6 in the side fence 5. The present invention has been proposed based on such a background, and an operation switch for performing operation of tilting or raising and lowering the floor of an electric bed can be attached to a side fence and removed when used. An object of the present invention is to provide a structure for mounting an operation switch in an electric bed that can be operated.

[0004]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, an embodiment of a structure for mounting an operation switch in an electric bed according to the present invention will be described with reference to the accompanying drawings. FIG. 1 shows an operation switch 1 for performing an operation of adjusting a tilt of a floor portion or an elevating control in an electric bed (described later).
0 is detachably provided on the side fence 11 provided on the side surface of the floor. That is, the operation switch 10
Is mounted on a recess 13 provided on an inner side surface of the side fence 11 facing the bed floor side of the fence unit 12. The operation switch 10 is a switch holder 14 that winds and accommodates an operation switch cord (described later).
And the switch holder 1 on the switch holder 14.
4 and a switch unit casing 15 which is configured to be detachably attached to the switch unit casing 4. An operation dial 16 for attaching the switch holder 14 to the inner surface of the fence 12 is provided on the outer periphery of the switch holder 14.
Is mounted so as to be rotatable with respect to. The side fences 11 provided on the side of the floor are provided on both sides, and the above-mentioned operation switch 10 can be selectively mounted on a side which is easy for the user to use according to other usage conditions. I have to.

As shown in FIG. 2, a screw hole 17 for mounting a switch holder 14 is formed in a concave portion 13 on the inner side surface of the fence portion 12, and a central portion of the bottom portion is provided with a screw hole 17.
A connector 18 is provided which is electrically connected to a controller (not shown) in the control. By screwing the switch holder 14 into the recess 13 on the inner surface of the fence 12 by the operation dial 16 into the screw hole 17, the operation switch cord L wound and housed in the switch holder 14 is electrically connected to the connector 18. Configuration.

The switch holder 14 has a base 14
The a-side outer shape has a substantially cylindrical shape, and a pair of holding members 19a and 19b for locking and holding the switch unit casing 15 are integrally provided on the base 14a. These holding members 19a and 19b have a width dimension of the switch unit casing 15 so as to be able to hold the switch unit casing 15, and locking grooves 20 are formed along end faces facing each other. The holding members 19a, 19b are provided on both end sides of the switch unit casing 15 sandwiching the switch unit 21 mounting surface.
A rib 22 for projecting and locking into the locking groove 20 in 19b is protruded.

The operation dial 16 has a cylindrical frame 23 rotatably mounted inside the base 14 a of the switch holder 14 and having a male screw screwed into a screw hole 17 in the recess 13. (See FIG. 3). Although not shown, the operation switch cord L that is wound in the base portion 14a is configured to rotate separately from the operation dial 16, and is wound with a predetermined urging force. The distal end of the operation switch cord L is connected to the connector 18 at the center of the screw hole 17 in the recess 13 via the cylindrical frame 23 of the operation dial 16 (see FIG. 4).

According to the mounting structure of the operation switch 10 as described above, when the operation switch 10 is not used.
Is the fence portion 12 of the side fence 11 in the bed 24,
The operation switch 10 can be mounted in the concave portion 13 on the inner surface facing the floor portion 25 side, and the operation switch cord L is not exposed by being wound and housed in the base portion 14a, so that the operation switch cord L is not exposed. It doesn't get in the way.

At the time of use, the user reaches his hand while lying on the floor 25, and the switch unit casing 1
By operating the switch of the switch unit 21 in 5, the inclination of the floor can be adjusted or the elevation can be adjusted. When the operation switch 10 is attached to the fence 12 of the side fence 11, it is difficult to operate the operation switch 10.
When the user is at a position away from 1, the switch unit casing 15 provided with the switch unit 21 is detached from the switch holder 14. That is, the switch unit casing 15 is connected to the pair of holding members 19a and 19a.
5 is pulled out in the direction in which b extends.
reference). The operation switch cord L in the switch unit casing 15 is housed in a wound state with an appropriate urging force in the base 14a. Therefore, by pulling the switch unit casing 15, the operation switch cord L can be easily moved into the base 14a. From the switch unit casing 1 on the floor 25.
5 can be operated while holding the switch. When the switch operation is completed, the switch unit casing 15 is moved to the pair of holding members 19 in the switch holder 14.
a, 19b, the pulled out operation switch code L is applied to the base 14 by a predetermined urging force.
a, the operation switch code L
Will not be pulled out. Therefore, even if the user releases his hand on the way, the operation switch code L
Is always in a state where the base 14a of the switch holder 14 is pulled, and as in the past, the operation switch cord that is loose on the floor 25 is hooked, and the operation switch may be dropped on the floor. Can be avoided. The operation switch 10 can be mounted on the side fence 11 closer to the dominant arm for use even when only one arm can be moved due to the dominant arm of the user or due to an injury or the like. .

[0011]

As described above, according to the present invention, (1) when not in use, the operation switch cord can be mounted so as not to be exposed on the side fence. Is not in the way, and a situation in which the operation switch cord is hooked and the operation switch is dropped on the floor can be avoided. (2) Since the operation switch can be brought to a position where it can be easily operated, the operable range is widened as compared with the side fence fixed type.
