DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a controller for a caregiver to operate a care lift on which an elderly person, a patient, and the like are placed.

[0002]

2. Description of the Related Art A conventional care lift for carrying a care recipient such as an elderly person, a handicapped person, or a sick person is used, for example, when the care recipient is moved from a bed for bathing or the like, as shown in FIG. The nursing lift L, which suspends and moves the care receiver A, is provided movably along a traversing rail R supported on both sides at the upper ends of a pair of right and left columns C, and the caregiver B operates an operation switch. S is operated to drive the care lift L up and down to move the care receiver A.
This type of conventional operation switch S is a push button type,
The caregiver B operates the care lift L by pressing buttons corresponding to an ascending operation, a descending operation, a stop, and the like.

[0003]

However, when the care lift is operated by using the push-button type operation switch as described above, the caregiver pays attention to the care receiver carried by the care lift L. While the position of the button of the operation switch must be checked, there is a possibility that the operation switch is erroneously operated.

Further, since the caregiver operates the operation switch with one hand, the caregiver cannot support the care receiver with both hands during operation of the care lift, and the caregiver is suspended by the care lift. Since the body swings and becomes unstable, the care receiver feels uneasy and there is a problem in safety.

Accordingly, the present invention is to solve the above-mentioned problems in the prior art, and to provide a controller for a care lift in which a caregiver can operate the care lift while supporting the care receiver with both hands. Aim.

[0006]

In order to achieve the above object, a controller for a care lift according to the present invention has a holding surface for pressing a palm and a hand holding the hand with the palm facing the holding surface from the outside. And a driven body that is supported by the controller body so as to be displaceable in a plane substantially parallel to the palm surface, and that is pressed against the body of the care receiver on the side opposite to the palm surface. A displacement member having a surface, an urging member for urging the displacement member to return to the neutral position of the controller main body, and detecting a relative displacement between the controller main body and the displacement member to the nursing lift. A displacement detection element that outputs a drive signal corresponding to the relative displacement.

[0007]

When the care lift controller of the present invention is used, the caregiver lifts the hand while operating the controller by inserting one hand into the holding portion of the controller body so that the palm faces the contact surface. The driven surface of the displacement member is positioned on the shoulder, back, etc. of the cared person placed on the car. Here, the driven surface faces the body of the care receiver from a direction substantially perpendicular to the operation direction of the care lift.

The caregiver supports the body of the care receiver with the other hand, and presses the palm of the person holding the controller against the contact surface of the controller body. When the face is pressed against the cared person, the cared person's body is supported by both the carer's non-controller hand and the driven face.

[0009] Here, when the caregiver applies a slight force in the direction of moving the cared person to the palm surface while pressing the driven face against the cared person's body, the displacement member is biased. The member is displaced in the opposite direction relative to the controller main body from the neutral position against the urging force of the member.

[0010] Then, the displacement of the displacement member is detected by the displacement detecting element, and a drive signal is output to the care lift, so that the care lift is driven so as to move the care receiver in the direction intended by the care giver.

When the caregiver loosens the pushing force of the controller, the displacement member returns to the neutral position of the controller body by the urging force of the urging member, and the displacement detecting element stops outputting a drive signal. Stops.

[0012]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below in detail with reference to the drawings. FIG. 1 is a view showing a first embodiment of a nursing lift controller according to the present invention. A nursing care lift controller (hereinafter simply referred to as a controller) 1 supports a care receiver A by suspending the care receiver A so as to be able to move up and down. The lift 2 is connected to a lift main body 2A by a signal cable 3 and is operated by a caregiver B.

The lift body 2A is movably supported by a traversing rail 6 which is horizontally supported between upper ends of a pair of right and left columns 4 and 4, and is lifted by a lifting belt 7, a suspension frame 8 and a sling 9. Thus, the care receiver A is suspended.

When the caregiver B operates the controller 1, the elevating belt 7 is moved to the lift body 2A.
The cared person A can be raised or lowered by being taken up by a motor driven winding drum (not shown) provided inside or taken out from the winding drum.

When the caregiver B supports the body of the cared person A with his / her hand and pushes or pulls in parallel with the longitudinal direction of the traversing rail 5, the lift main body 2A moves along the traversing rail 5, and The position of the person A can be moved in the lateral direction.

FIG. 2 is a cross-sectional view showing the structure of the controller 1 as viewed from the side, and FIG. 3 is a front view, which has a controller body 10 integrally formed of resin. The displacement member 11 has upper and lower thin deformed portions 11A, 1
1B are integrally connected.

The thin deformed portions 11A and 11B are capable of elastically deforming vertically and have a function as an urging member in the present invention, and no external force is applied to the displacement member 11. In the state, the displacement member 11 is at a neutral position as shown in FIG. 2, and is elastically displaced up and down above the neutral position by the action of an external force.

A detection member 12 made of a magnet is embedded on the back side of the displacement member 11.
The detected member 12 is detected by the reed switch 13A when 1 is displaced upward from the neutral position relative to the controller body 10, and is detected by the reed switch 13B when displaced relatively downward from the neutral position. It has become. These reed switches 13A and 13B are used as displacement detecting elements in the present invention.

FIG. 4 is a circuit diagram between the care lift and the controller. The reed switch 13A is closed by the upward displacement of the detected member 12 with respect to the controller main body 10, and the lift main body 2A of FIG. The signal is output to the built-in drive circuit 14. Then,
The drive circuit 14 rotates a motor 15 for raising and lowering the elevating belt 6 in FIG.
Cared person A descends.

When the reed switch 13B is closed due to the relative displacement of the detected member 12 downward with respect to the controller body 10, the drive circuit 14 rotates the motor 15 in the direction in which the elevating belt 6 is wound up, and A rises.

On the surface of the controller body 10 opposite to the surface on which the displacement member 11 is provided, a contact surface for pressing the palm when the caregiver B operates the controller 1 as shown in FIG. 16 are formed.

In addition, holding hooks 17 and 18 are integrally formed on the controller main body 10 as holding portions for holding a hand whose palm faces the abutment surface 16 from the outside. With the palm facing the palm surface 16, the holding hook 1
The controller 1 can be held by inserting the hand H into the inside of the insides 7 and 18 as shown in FIG.

On the other hand, the front side of the displacement member 11 is shown in FIG.
The driven face 11C is pressed against a body part such as the shoulder or the back of the care receiver A suspended from the care lift 2 shown in FIG.

When the position of the care receiver is to be moved upward, the caregiver supports the body of the care receiver with the hand not having the controller 1, and as shown in FIG. 11 to the driven face 11C
Against the body.

Here, when a slight upward force is applied to the controller body 10, the displacement member 11 has its driven surface 11C pressed against the body of the care receiver A.
The frictional force causes the elastic displacement relative to the controller body 10 downward.

As a result, the member to be detected 12 is detected by the reed switch 13B, and the raising / lowering belt 6 of the care lift 2 is wound up by the detection signal, and the care receiver A moves upward. In order to stop the care receiver A from rising, when the upward force applied to the controller body 10 is relaxed, the displacement member 11 returns to the neutral position due to elasticity, and the reed switch 13
Since B stops detecting the detected member 12, the care lift 2 stops.

On the other hand, when lowering the care receiver A,
When the driven surface 11C of the displacement member 11 is slightly pressed down to the controller body 10 in a state where the driven surface 11C is pressed against the body of the care receiver A, the detection member 12 is detected by the reed switch 13A, and the lifting belt 6 of the care lift 2 is extended. Thus, the care receiver A can be lowered to the target position.

When a detection signal serving as a drive signal is output from the limit switch 27A to the care lift 2 via the signal cable 3, the motor in the lift body 2A is driven in the direction of winding the lifting belt. , Cared person A
Can be raised.

When there is no external force applied to the displacement member 19,
The striker 24 returns to the neutral position by the elastic force of the compression coil springs 25 and 26, and the lifting operation of the care lift 2 stops. When the care receiver A is lowered, a slight downward force may be applied to the controller main body 10A in the same manner as when the care receiver A is raised.

Next, FIG. 8 is a sectional view showing a third embodiment of the controller for a care lift of the present invention, and FIG.
It is sectional drawing seen in the arrow direction at the X-ray position. In the controller 1B shown in these drawings, a striker 31 having a square cross section integrally formed at the center of the back surface of the controller 1B is provided inside the controller body 10B so that the displacement member 30 can be displaced up and down and left and right with respect to the controller body 10B.
