Description

[Detailed description of the invention] [Field of industrial application] The present invention allows a suspended and supported person to move up and down freely while being supported, and also to move freely in a horizontal plane while being suspended and supported at an arbitrary height. The present invention relates to a support device for nursing care that is capable of providing support for nursing care.

[Conventional technology]

BACKGROUND ART Conventionally, various load handling devices formed by arm structures using pantograph-like parallel links have been proposed and put into practical use, and there is also an opportunity to use these devices as support devices for nursing care.

[The problem that the idea attempts to solve]

However, since the above-mentioned load handling device was designed to be used for handling heavy objects in factories, cargo handling workshops, etc., it was difficult to find a way to lift, lower, or horizontally move the cargo to be handled in a labor-saving manner. Most of them are designed from a viewpoint, and therefore, the drive source uses a motor or cylinder with a large output, and the power transmission system tends to be complicated, so the device is inevitably large and heavy. It was hot.

Recently, attention has been paid to the fact that the load handling device mentioned above is capable of raising and lowering the load support part and can be moved freely in a horizontal plane, and this device has been developed to be used for so-called bedridden elderly people and people with physical disabilities. Attempts have been made to use this device as a nursing care support device for suspending and supporting a person who is unable to walk, etc., via a sling belt, etc., during urination or bathing.

However, load handling devices originally developed and designed for industrial use have the problem of being too large and too heavy to be installed indoors in facilities such as ordinary private homes and hospitals. There is. Furthermore, the above-mentioned device has an excessive operating function as a support device for nursing care, and therefore, the device is also disadvantageous in that it is too expensive.

In view of these circumstances, the present invention is small and lightweight, suitable for installation indoors, etc., and has sufficient functionality as a device for suspending and supporting a person to be cared for while urinating or bathing. The object of the present invention is to provide a support device for nursing care.

[Measures to solve the problem]

The present invention was developed with the aim of solving the above problems, and its configuration consists of a bracket 2 that is attached to a support 1 that is erected on the ceiling or floor so as to be pivotable in a plane, and a bracket 2 that is parallel to the horizontal direction. Two arms 3 and 4 are attached to the rear end side so as to be able to swing up and down, and the front ends of the parallel arms 3 and 4 are connected to the support column 1 via a parallel connection link 5. A second arm 6, which is slightly shorter than the arms 3 and 4 and is oriented laterally and is rotatable on an axis parallel to the support column 1, is attached to the tip side of the second arm 6, and a support section is attached to the tip side of the second arm 6. While forming 7;
A tension arm 8 which gives an appropriate depression angle to the two arms 3 and 4 is protruded from the bracket 2, and a rope body 10 paid out from a hoisting mechanism 9 provided on the bracket 2 is attached to the tension arm. It is characterized in that it is connected to the distal ends of the two arms 3 and 4 via the distal ends of the arms 8.

[Effect]

Two parallel arms attached to a bracket rotatably attached to the column are retracted into the hoisting mechanism,
The cable is moved up and down relative to the support by the unwound cable.

A support portion formed on the distal end side of the second arm rotatably attached to the distal end side of the parallel arm is raised and lowered by vertical swinging of the parallel arm, and rotates around the vertical axis of the bracket and the second arm. It can be moved in a plane by turning.

〔Example〕

Next, an embodiment of the present invention will be described with reference to the drawings.

Fig. 1 is a skeleton diagram showing an example of the device of the present invention;
The figure is a skeleton diagram of the main parts of another example.

In Fig. 1, 1 is a column erected on the ceiling C or floor F. It is optional whether this column 1 is a movable type or fixedly installed, but here it is a floor erected type. .

Reference numeral 2 denotes a cylindrical bracket attached to the upper end side of the column 1, which can freely rotate on its axis relative to the column 1. 2a is its turning pivot.

3 and 4 are two horizontally parallel arm members whose rear ends are pivotally connected to the bracket 2 by horizontal shafts 3a and 4a, and the tips of these parallel arm members 3 and 4 are as follows.
A shaft 3 is attached to a cylindrical connecting link 5 parallel to the column 1.
The parallel arm members 3, 4 are pivotally connected by shafts 3b, 4b parallel to the
is parallel to the axis 3 relative to the bracket 2.
It is vertically swingable about a and 4a, and since the bracket 2 is rotatable relative to the support 1, it is also pivotable within a plane relative to the support 1.

Reference numeral 6 denotes a horizontal second arm member having a vertically oriented shaft portion 6a rotatably inserted into the cylindrical portion of the connecting link 5, and a tip 6b of this arm member.
A support 7 is formed. In this figure, the second arm member 6 is inclined slightly downward, but the arm member 6 may be horizontal or may be inclined at any other suitable angle. Further, the arm member 6 is rotatably attached to the cylindrical portion of the connecting link 5 parallel to the support column, so that the arm member 6 can freely rotate around the axis of the connecting link 5.

Reference numeral 8 denotes a tension arm provided in the bracket 2 so as to protrude at an upward angle from above the pivot shaft 3a of the horizontal arm member 3. In this embodiment, the tip of the arm 8 is a parallel arm. The length of the arms is adjusted so that the arms are positioned above the distal ends of the members 3 and 4.

Reference numeral 9 denotes a hoisting mechanism disposed at the upper end of the bracket 2, which is not shown in the drawings, but is here formed by a motor, a speed reducer, a hoisting cylinder, and a rope body 10 such as a belt wound around this cylinder. .

Thus, the cable 10 is let out from the hoisting machine groove 9, and the tip side of the cable 10 is connected to the tension arm 8.
It is connected to the distal end of the parallel arm member 3 via a relay ring 8a provided at the distal end of the parallel arm member 3.

As shown in FIG. 2, the distal end of the cable 10 is routed through a relay ring 8a and then through a relay ring 3c provided at the distal end of the parallel arm member 3. may be fixed to the tip of the tension arm 8.

The above constitutes an example of the device of the present invention.
By configuring the support device for nursing care in this way, when a person who requires nursing care supported by a sling belt or the like is suspended from the support section 7 and the motor output of the hoisting mechanism 9 is appropriately controlled, the person is suspended from the support section 7. The supporter can be raised and lowered, and the bracket 2 can be moved up and down from the support 1 at any desired height in this suspended state.
and/or by pivoting the second arm member 6 relative to the connecting link 5,
Each arm member 3,
It can be freely translated in parallel within a length range of 4 and 6.

[Effect of idea]

In the device of this invention, the hoisting force from the hoisting mechanism is transmitted to the tip of the parallel arm member attached so as to be able to swing up and down with respect to the support column through the rope body connected via the tip of the tension arm. While the force is applied almost directly above the parallel arm member in the vicinity of the tip thereof, the second arm member is rotatably attached to the tip of the parallel arm that is vertically oscillated in this way. Since the support part is formed at the tip, the load applied to the support part is supported using the tip of the arm as a fulcrum, and therefore, the hoisting mechanism does not require much force to drive the hoisting mechanism.
The winding mechanism can be made smaller.

Furthermore, the parallel arm member is rotatable by 360° or more with respect to the support column, and the second arm member can be rotated by 360° or more at the tip of the parallel arm member, so that the planar movable range of the support portion 7 is In addition to being wide, it is easy to position it at any height and location within this flat movable range.

Furthermore, since each arm member is not provided with any guide mechanism or the like that would increase its weight, the arm member itself can be made of a lightweight and compact material, making it possible to combine it with the above-mentioned compact hoisting mechanism with a small driving force. Together, this is extremely advantageous in reducing the weight and size of the device.

Therefore, the device of the present invention is extremely useful as a support device for nursing care that is installed and used indoors.
