Abstract

PURPOSE:To provide a switch ready to hand in a bed constituted so as to be equipped with a lamp for night illumination. CONSTITUTION:A lamp 6 is attached to the top part of a casing 5 equipped with operation switches Sw1, Sw2 for raising and lowering the back, switches Sw3, Sw4 for raising and lowering a knee and operation switches Sw5, Sw6 for raising and lowering the whole of a bed part 2 and a lighting operation switch SwL for the lamp 6 is installed. The lighting operation switch SwL is turned ON to supply a lighting operation signal (current signal) to the transistor 7 of a lighting circuit 7 and the collector and emitter of the transistor 8 are brought to a continuity state to allow the lamp 6 to light. Since the lamp of a switch ready to hand can be allowed to approach a bed head stand or can illuminate the lower part of a bed by this constitution, a small articles can be easily taken out and action looking for something can be easily performed.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hand switch in a bed provided with a lamp for night lighting.

[0002]

2. Description of the Related Art Conventionally, lights are turned off at night in hospitals, and in a patient room where many patients live together, a bedside bed is provided with a small lamp for lighting, so After the turning-off time has passed, they have been used individually for lighting.

[0003]

However, the above-mentioned desk lamp only illuminates the periphery of the bedside, for example, when a small object is dropped under a bed or inside a door or a drawer in a bedside cabinet. When taking out small items, it was necessary to hold the table lamp in hand and bring it close to illuminate it, which made it difficult to use, so it was necessary to prepare a flashlight for such a case. Therefore, recently, a bed equipped with an electric floor raising / lowering mechanism, which is increasing in number, has a hand switch that can perform a floor raising / lowering operation on the floor, so that the hand switch is used for lighting. We came to the point of not being able to double use. The present invention has been proposed in view of such a background, and an object of the present invention is to provide a hand switch in a bed provided with a lamp for night lighting.

[0004]

In order to solve the above-mentioned problems, the present invention provides a bed provided with an electric floor undulating mechanism, comprising a casing mounted with an operation switch for floor undulating operation, A lamp for night illumination is provided on the casing, and a lighting operation switch for lighting the lamp is provided.

[0005]

[Action] In the sickroom, after turning off the light, pressing the light switch on the hand switch turns on the lamp, for example, taking out necessary items, leaving the device around the bed,
When looking for things that have fallen to the floor, you can hold the hand switch in your hand, pull the hand switch's signal cable and bring it close to it to illuminate, so it is easy to use and easy lighting As a function.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, a hand switch in a bed according to the present invention will be described below with reference to the accompanying drawings, taking an embodiment. FIG. 1 shows a bed 1 provided with an electric floor raising / lowering mechanism. This bed 1 includes a hand switch 3 for operating an electric floor raising / lowering mechanism (not shown) on a floor 2. , Hand switch 3 is bed 1
A control box (not shown) mounted on the frame is connected by a signal cable 4, and an operation command signal from a hand switch 3 is supplied to the control box to control the operation of the floor undulating mechanism. As shown in FIG. 2, the hand switch 3 includes operation switches Sw ₁ and Sw ₂ for raising and lowering the back of the casing 5, Sw ₃ and Sw ₄ for raising and lowering the knee, and an operation for raising and lowering the entire floor 2. The switches Sw ₅ and Sw ₆ are provided. Then, the vertex portion of the casing 5, while the lamp 6 (about DC3V used for ordinary flashlight) is provided, the operation switch Sw ₁ to SW ₆ is provided a surface,
A lighting operation switch SwL for the lamp 6 is provided.

In the hand switch 3 as described above, a lighting circuit 7 as shown in FIG. 3, for example, can be applied as a circuit for lighting the lamp 6. That is, the lighting circuit 7 is a switching circuit using the transistor 8, and the lighting operation switch SwL is connected to the base terminal.
Are connected to supply a lighting operation signal (current signal). A DC power supply of 3 V is applied from a control box to a collector terminal of the transistor 8 via a resistor R, and a lamp 6 is connected in series to an emitter terminal. A well-known lighting operation switch SwL for supplying a lighting operation signal to the lighting circuit 7 can be used, for example, the first pressing operation turns the switch ON to maintain the ON state. It is possible to apply a system in which the lighting operation signal is continuously supplied to maintain the lighting state of the lamp 6, the lamp 6 is turned off by the next pressing operation, the lighting operation signal is cut off, and the lamp 6 is extinguished. .

[0008] The hand switch in the bed according to the present invention is configured as described above. Next, this operation will be described. In the sickroom, when the lighting operation switch SwL of the hand switch 3 is pressed after the light is turned off, an operation signal (current signal) is supplied to the base terminal of the transistor 8. As a result, the collector and the emitter are electrically connected to each other, and the collector current flows to the lamp 6 by the DC power supply 3V so that the lamp 6 can be turned on. The lighting operation switch S
If a method of maintaining the ON state in the first pressing operation is applied to wL, it is convenient because the lamp 6 continues to light even if the pressing operation is performed once and then the hand is released. For example, when taking out a necessary item or searching for the area around the bed 1, the user holds the hand switch 3 in his hand, pulls the signal cable 4 of the hand switch 3, and holds the hand switch 3 close to it. By pressing the lighting operation switch SwL, the lamp 6 can be turned on and illuminated, so that the function can be greatly exhibited for simple lighting.

[0009]

As described above, according to the present invention, after the extinction time has elapsed, the lamp operation switch of the hand switch of the bed is operated to turn on the lamp, and while pulling the signal cable of the hand switch, the lamp is turned on. , For example, close to the floor stand,
Since it is possible to illuminate the lower part of the bed, it is possible to easily take out small items or search for items.
