The retractable side fence 2 has, for example, a column 4 attached to a bed frame (not shown) for supporting the bottom 3 of the bed 1 so that the column 4 can protrude from below the bottom 3 to above the bottom 3. The fence 5 is rotatably supported. An operation switch 6 (hereinafter, a hand switch 6) for operating a floor undulating mechanism is selectively provided on the inner side surface facing the bottom 3 side of the fence portion 5 of both of the retractable side fences 2 having such a configuration. A connection relay means (described later) for detachably mounting is provided. From these connection relay means, a cable 8 is connected via a relay connector 7 arranged below the bottom 3.
It is wired so as to reach a controller (not shown).

The hand switch 6 is configured to be mounted in a concave portion 9 provided on the inner surface facing the bottom 3 of the fence portion 5 of the retractable side fence 2. As shown in FIG. 2, the hand switch 6 has a configuration in which a signal cable (to be described later) is wound up and accommodated therein, and a switch holder 10 on the switch holder 10 and which is detachably mounted on the switch holder 10. The switch unit casing 11 is used. On the switch holder 10, an operation dial 12 for attaching to the connection relay means on the inner surface of the fence 5 is provided on the outer periphery of the switch holder 10.
Is mounted so as to be rotatable with respect to. On the other hand, the bottom 3 of the fence 5 to which the hand switch 6 is not attached
A protection cap member 13 is attached to the concave portion 9 provided on the inner side surface facing the side (see FIGS. 1 and 3).

In the recess 9 on the inner surface of the fence 5,
As shown in FIG. 4, a screw hole 14 for mounting the switch holder 10 as a connection relay means, and a connector 15 electrically connected to a controller (not shown) are provided at the center of the bottom. I have. By screwing the switch holder 10 into the recess 9 on the inner surface of the fence 5 with the operation dial 12 into the screw hole 14, the signal cable 16 wound and housed in the switch holder 10 is connected to the connector 15.
It is configured to be electrically connected to The protective cap member 13 has a knob 13a whose outer periphery is formed in a polygonal shape so as to be easily gripped, and a screw of the concave portion 9 on the inner side surface of the fence 5 where the switch holder 10 is not mounted. A bore 14 is provided with a cylindrical base (not shown) threaded along its outer circumference so that it can be screwed.

The switch holder 10 has a substantially cylindrical outer shape on the base 10a side, and a pair of holding members 10b and 10b for locking and holding the switch unit casing 11 are integrally provided on the base 10a. I have.
These holding members 10b, 10b have a width dimension of the switch unit casing 11 so as to be able to hold the switch unit casing 11, and locking grooves 17 are formed along opposing end surfaces. Then, holding members 10b, 10b are provided on both end surfaces of the switch unit casing 11 sandwiching the switch unit 18 mounting surface.
A rib 19 for fitting and locking into the locking groove 17 is provided. Although not shown, the signal cable 16 is connected to the operation dial 1 in the base 10a.
2 is wound around a member that rotates separately, and can be configured to apply a predetermined urging force to this member.

According to the mounting structure of the hand switch 6 as described above, when the hand switch 6 is not used, the hand switch 6 is inserted into the recess 9 on the inner surface facing the bottom 3 of the fence 5 of the retractable side fence 2. And the signal cable 16 is not exposed by being wound and housed in the base 10a, so that it does not disturb the user.

At the time of use, the user reaches his hand while lying on the bottom 3 to reach the switch unit casing 1.
By operating the switch of the switch unit 18 in 1, the inclination of the floor can be adjusted or the elevation can be adjusted. The switch unit 18 is provided when it is difficult to operate the hand switch 6 when the hand switch 6 is attached to the fence 5 of the retractable fence 2 or when the user is away from the retractable fence 2. Switch unit casing 1
1 is removed from the switch holder 10. That is, the switch unit casing 11 is formed by a pair of holding members 10b,
Pull out in the direction in which 10b extends.
Since the signal cable 16 in the switch unit casing 11 is housed in the base 10a in a wound state with an appropriate urging force, the signal cable 16 can be easily pulled by pulling the switch unit casing 11.
Can be pulled out from the base 10a, and the switch operation can be performed while holding the switch unit casing 11 on the bottom 3. When the switch operation is completed, the switch signal casing 16 is pulled out by holding the switch unit casing 11 above the pair of holding members 10b and 10b in the switch holder 10.
Is wound and housed in the base 10a with a predetermined urging force, so that the signal cable 16 is not pulled out. Therefore, even if the user releases his hand on the way, the signal cable 16 is always in a state where the base 10a of the switch holder 10 is pulled, and the operation switch cord which is loosened on the bottom 3 as before. Can be prevented from dropping the operation switch on the floor.

On the other hand, the protective cap member 13 is screwed into the screw hole 14 in the concave portion 9 of the fence 5 where the hand switch 6 is not mounted, so that the connector 15 is not exposed. An unexpected situation in which water or the like is applied to the connector 15 by mistake or by mischief of a child, a dementia patient or the like can be avoided. Even when only one arm can be moved by the user's dominant arm or by injury, the hand switch 6 can be selectively mounted on the retractable side fence 2 closer to the dominant arm for use. Easy to use.

[0012]
