Abstract

PURPOSE:To enable a floor to be raised and lowered at a greater speed than the normal speed in an emergency or when needed. CONSTITUTION:In addition to a control switch 8 for normal raising and lowering action, a control knob 9 that emits a control signal to a motor 3 to adjust the rotation speed of a motor 3 via a motor control part 6 is provided to an at-hand switch 5. The motor control part 6 is designed to apply driving voltage to the motor 3 in response to the control signal emitted by the control knob 9, so as to increase the speed of the motor 3 to increase the speed at which a back bottom is raised or lowered, after 40 seconds of raising and lowering action. The speed at which the back bottom is raised or lowered is thus increased in an emergency or when needed so as to provide greatly enhanced serviceability.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electric floor undulation in a bed, which can adjust the undulation speed of the floor to a speed higher than the undulation speed in normal times in an emergency or when necessary. It is related to the mechanism.

[0002]

2. Description of the Related Art Recently, beds equipped with an electric floor undulating mechanism (hereinafter referred to as "electric beds") have become widespread. That is, such an electric bed has a motor arranged on the lower side of the floor and a floor undulating mechanism operated by the motor, and by operating a hand switch as a remote control means, via a control box equipped with a motor control unit, It is configured to give an operation control signal to the motor.

[0003]

However, since the motor and the floor undulating mechanism are usually connected via a speed reducing mechanism having a predetermined reduction ratio, the floor of the electric bed has a predetermined undulating speed. It only has the function of working in. The undulation speed is set to a speed that does not cause a problem during normal use by the patient. Therefore, for example, in an emergency or during a test of undulation operation, for example, there is a problem that the above-described undulation speed is too slow and inefficient. The present invention has been proposed in view of the above background, and an object of the present invention is to provide an electric floor undulating mechanism in a bed that can be operated at a high undulating speed except during normal use. .

[0004]

In order to solve the above-mentioned problems, the present invention provides an electric floor undulating mechanism for a bed, which is provided with an adjusting means for adjusting the undulating motion speed of the floor. Characterize. Further, according to the present invention, in the electric floor undulating mechanism in a bed configured to give an operation control signal to the motor to undulate the floor by operating the remote operating means, the rotation speed of the motor is adjusted by the remote operating means. It is characterized in that an operating means for doing so is provided.

[0005]

[Function] When carrying out a normal undulating operation with the patient on, the remote operating means is operated at a normal undulating speed, and in an emergency or when necessary, the rotation speed of the motor of the remote operating means is adjusted. By operating the operating means for performing the undulation operation at a higher undulation speed than the normal undulation speed.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An electric floor undulating mechanism in a bed according to the present invention will be described below with reference to the accompanying drawings. FIG. 1 shows an electric floor undulating mechanism 1 in a bed.
Is to adjust the back bottom 2 of the bed up and down,
It has a motor 3 arranged below the floor and an activation arm 4 which is driven forward and backward by the motor 3, and when a hand switch 5 is operated, an operation control signal is sent to the motor 3 via a motor control unit provided in a control box 6. It is configured to give. The back bottom 2 is connected to the activation arm 4 via a protruding portion 7 protruding from the back bottom 2. Further, the hand switch 5 includes an operation switch 8 for normal undulation operation.
In addition to the above, an adjustment knob 9 for issuing a control signal for adjusting the rotation speed of the motor 3 is provided to the motor 3 via a motor control section provided in the control box 6.

The motor control section provided in the control box 6 includes an operation switch 8 in the hand switch 5.
And the motor 3 based on the signal from the operation of the adjusting knob 9.
An operation control signal is given to the above, and the outline of the control configuration will be described. The motor control unit uses the operation signal from the operation switch 8 for normal undulation operation to set the drive voltage to operate the motor 3 at the rotation speed such that the undulation speed of the back bottom 2 is 40 seconds. It is configured to be applied to the motor 3 (see FIG. 2). In addition, the motor control unit uses the operation signal from the adjusting knob 9 to increase the undulation speed of the back bottom 2 from the undulation operation time of 40 seconds to increase the rotation speed of the motor 3 to appropriately increase the undulation speed. It is configured to be given to 3. The motor control unit may be configured such that the drive current is controlled by an operation signal from the operation switch 8 for up-and-down operation and the adjusting knob 9, and the motor 3 is driven by the controlled drive current.

As a control structure for adjusting the rotation speed of the motor 3, a variable resistor (not shown) is provided on the adjusting knob 9.
It is possible to adopt a configuration in which a drive voltage corresponding to the resistance value is applied to the motor 3 from the motor control section by mounting the motor and adjusting the resistance value. It is also possible to detect the adjustment amount of the variable resistor in the adjustment knob 9 and apply the drive voltage corresponding to the adjustment amount to the motor 3 from the motor control unit. As shown in FIG. 3, in addition to the adjustment knob 9 described above, an adjustment dial 11 may be provided on the back surface of the casing 10 of the hand switch 5 to perform stepless adjustment. Further, the adjusting dial 11 may be adjusted stepwise.

The electric floor undulating mechanism 1 in the bed according to the present invention is constructed as described above. Next, the operation of the electric floor undulating mechanism 1 will be described. When carrying out the undulating operation of the back bottom 2 with a patient on it, a signal from the operation of the operation switch 8 of the hand switch 5 is given to the motor control section in the control box 6, and the motor control section is operated based on the operation signal. In order to operate 3, the drive voltage can be applied to the motor 3, and the back bottom 2 can be undulated at an undulation speed such that the undulation operation time is 40 seconds.

Then, in an emergency or when necessary, when the adjustment knob 9 of the hand switch 5 is operated, the motor control section receives the operation signal to change the undulation speed of the back bottom 2 from the undulation operation time of 40 seconds to the motor. In order to increase the number of rotations of 3 to increase the undulation speed appropriately, a drive voltage can be applied to the motor 3 to perform the undulation operation on the back bottom 2 at an undulation speed higher than the above-described undulation speed.

As described above, during normal undulating motion,
The urging operation time which is said to be safe is performed at an undulation speed of 40 seconds, and in an emergency or when necessary, the undulation operation time is adjusted from the undulation speed of 40 seconds to a high speed speed so as to undulate at a high speed. Since the number of rotations of the motor 3 can be increased by operating 9 and the back bottom 2 can be raised and lowered at a moderately raised and lowered speed, it is possible to deal with the usage situation and improve the usability.

[0012]

As described above, according to the present invention, a patient can perform a hoisting operation at a hoisting speed that does not cause a problem during normal use, and in an emergency or when necessary, operate the hoisting speed at a high hoisting speed. Because it can be done, usability is greatly improved.
