DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an overhead traveling type nursing care apparatus in which a nursing lift reciprocates on a traveling rail laid on an indoor ceiling.

[0002]

2. Description of the Related Art Conventionally, various devices have been devised for an overhead traveling type nursing care device which can easily move a care receiver by a nursing lift which reciprocates a traveling rail laid on an indoor ceiling in a hospital or home. For example, there is a cable in which a power supply cable for supplying electric power to the lift drive motor of the nursing care lift is exposed along the travel rail, and a power supply cable is provided inside the travel rail.

[0003]

However, in the overhead traveling type nursing care device in which the power supply cable is exposed and installed around the traveling rail as in the former, the exposed and installed power supply cable impairs the beauty of the nursing care room and is used for the nursing lift. There has been a problem that running obstacles are liable to occur due to confounding with a wiring cord for an operation switch, which hangs down in proximity.

[0004] On the other hand, an overhead traveling type nursing care device in which a power supply cable such as the latter is installed inside a travel rail solves the problem as in the former, but the power supply cable is moved along with the movement of the care lift. Frequent sliding contact with the inner wall of the car may cause problems such as confounding, disconnection, and leakage.
It must be installed inside the traveling rail using a flexible surrounding body that protects the power supply cable, so that the traveling rail is bulky and its weight increases, and the construction work load on the indoor ceiling, There has been a problem that inconvenience is caused by the support strength of the indoor ceiling, the laying space, and the like.

[0005] Further, both of the overhead traveling type nursing care devices are capable of raising and lowering the nursing care lift by supplying power to a lifting drive motor from a power supply cable, but neither of them has a self-propelled driving mechanism. You cannot run on the rails.

Therefore, in the conventional overhead traveling type nursing care device, the caregiver must manually move the care lift to the position where the care lift should be moved, and also cares the care receiver freely at the moved position. In this case, the caregiver needs to evacuate the care lift promptly, or if the indoor ceiling or running rail is distorted and tilted, the care lift may Since it is unevenly located at the lowest position, it has to be moved to an appropriate position each time, which requires a troublesome moving operation.

[0007] A self-propelled drive mechanism for self-propelling the nursing care lift can be incorporated in the conventional overhead traveling type nursing care device. In this case, however, it is possible to avoid an increase in the size of the device structure and an increase in the cost of the device. In addition, there is a problem that an operation switch or the like must be operated to reciprocate and self-propelled while caring for the cared person, and the caring operation is not always simple.

Therefore, an object of the present invention is to make it possible to easily perform a reciprocating operation of a nursing care lift, to reduce a load strength on an indoor ceiling, a laying space, a construction load and equipment costs, and to further reduce a nursing care space. An object of the present invention is to provide an overhead traveling type nursing care device capable of improving aesthetic appearance.

[0009]

An overhead traveling type nursing care device according to the present invention is an overhead traveling type in which a traveling shuttle of a nursing lift reciprocates on a traveling rail laid on an indoor ceiling. In the nursing care device, the spirally extending / contracting portion of the power supply cable for supplying power to the hoist mechanism of the nursing lift is installed in the traveling rail while being held at the start end of the traveling rail and the traveling end of the traveling shuttle. The problem is solved by allowing the care lift to be pulled back from the moving position to the fixed starting position by the pulling-back force of the spiral expandable portion.

[0010] According to a second aspect of the present invention, in addition to the first aspect of the present invention, there is provided an overhead traveling type nursing care device which includes a pair of front and rear mounted on the traveling rail. The above-mentioned problem is further solved by the fact that a wheel running area for running the driven wheels and a power supply cable enclosing area in which the spiral expansion and contraction portion of the power supply cable is provided are partitioned via a side wall opened upward. It is.

According to a third aspect of the present invention, in addition to the first or second aspect of the present invention, there is provided an overhead traveling type nursing care device, in which the nursing lift travels at a terminal end of the traveling rail. The problem is further solved by providing a latch member for mooring the shuttle.

Here, the nursing lift according to the present invention comprises a traveling shuttle having at least a pair of front and rear driven wheels traveling on a traveling rail, a hoist mechanism suspended from the traveling shuttle, and a hoist mechanism for winding the hoist mechanism. A device provided with a body holder suspended vertically so as to be able to move up and down by a belt, a hoisting rope, or the like, and having a self-propelled driving mechanism for self-propelled running on a traveling rail is not applicable.

The spirally extending and contracting portion of the power supply cable according to the present invention may be formed over the entire length of the power supply cable. However, as long as the cable length is sufficient to be able to expand and contract within the traveling rail, the nursing care lift is provided. The pull-out force that pulls the wire from the moving position to the fixed starting position can be sufficiently exerted, so that there is no need to secure extra arrangement space for the wiring section extending from the power cable enclosing area of the traveling rail, and the size is reduced. It becomes possible to design the layout of the device.

Further, when a non-conductive material having a low coefficient of friction is coated or adhered to the inner peripheral surface of the running rail to which the spirally extending and contracting portion of the power supply cable can slide and the outer peripheral surface of the driven wheel. The traveling shuttle of the nursing care lift can be moved more smoothly, and the traveling shuttle of the nursing care lift can be moved within the traveling rail regardless of whether the traveling rail is laid straight or curved. It can be freely reciprocated without any resistance.

Further, in the case where the holding portions of the power supply cables are provided at both ends of the traveling rail according to the present invention, the starting end of the traveling rail can be positioned according to the indoor power distribution layout. This facilitates on-site construction work and indoor space usability.

[0016]

The overhead traveling type nursing care device of the present invention has the following operation since it has a power supply cable layout specific to the present invention. In other words, the spiral expansion / contraction part of the power supply cable that supplies power to the hoist mechanism of the nursing care lift,
By being erected in the traveling rail while being held at the starting end of the traveling rail and the traveling tip of the traveling shuttle, the spirally extending and retracting portion of the power supply cable can be provided at any traveling position of the traveling shuttle of the nursing care lift. Only when the expansion / contraction action occurs and this expansion / contraction action does not occur in other parts, and when the spiral expansion / contraction part expands to generate a retraction force, the care lift utilizes the retraction force. Then, it is spontaneously pulled back from the moving position to the fixed starting position.

In the traveling rail, a wheel traveling area provided on the traveling shuttle of the nursing lift for traveling a pair of front and rear driven wheels and a power supply cable enclosing area in which a spiral expansion and contraction portion of the power supply cable is provided are opened upward. The driven wheel of the traveling shuttle is separated from the spirally extending and contracting portion of the power supply cable at any moving position by being partitioned via the side wall, and the hoist mechanism extends from the spirally extending and contracting portion. A constant length of cable is always ensured regardless of the movement position of the power supply cable connected to the vehicle, so that the driven wheels of the traveling shuttle can smoothly and reliably move on the traveling rail without biting the spiral expansion / contraction part. You can travel.

A latch member for mooring the travel shuttle of the care lift is provided at the end of the travel rail, thereby forcibly preventing a retraction force for returning the care lift from the moving position to the fixed starting position. Therefore, the nursing care lift can be moored even when the indoor ceiling or the running rail is distorted and presents an inclined state.

1a is rotatably fixed to the side of the shuttle frame 21b, and a hoist mechanism 22 of the care lift 20 is fixed to a bottom bracket 21c extending outside the rail of the shuttle frame 21b. .

The hoist mechanism 22 of the care lift 20 is connected to a power supply cable 40 for supplying power from a power outlet on an indoor wall (not shown) via the traveling rail 10 and the traveling shuttle 21.

On the other hand, as shown in FIG. 3, the running rail 10 has a wheel running area 11 for running the driven wheel 21a and a spirally extending / contracting portion 41 of the power supply cable 40.
Are arranged inside each other via a side wall 13 opened upward. In addition, on the inner peripheral surface of the traveling rail 10,
In order to move the traveling shuttle 21 of the care lift 20 more smoothly, a non-conductive material having a low coefficient of friction is attached.

Therefore, the power supply cable 40 is laid on the power supply cable enclosing area 12 of the traveling rail 10 in a state where the spiral-shaped expansion / contraction portion 41 is held at the starting end of the traveling rail 10 and the traveling tip of the traveling shuttle 21. Yes,
The nursing care lift 20 is pulled back from the moving position to the fixed starting position by the pulling-back force of the spiral expandable portion 41. In addition, since the power supply cable 40 does not have a spiral cable form in a wiring part extending from the power supply cable inclusion area 12, it is not necessary to consider an extra space for arranging this part. Design layout becomes possible.

As shown in FIG. 4, the traveling shuttle 21 of the care lift 20 is provided at the end of the traveling rail 10.
Is provided, and when the pulling force is generated to return the care lift 20 from the moving position to the fixed starting position, the indoor ceiling C and the traveling rail 10 are distorted and tilted. , The care lift 20 can be moored arbitrarily according to the care situation. Reference numeral 15 shown in FIG. 4 is a stopper cushion made of synthetic rubber or the like, and reference numeral 2 is a latch engaging portion 21d provided on the traveling shuttle 21 that removably engages with the latch member 14.

The overhead traveling type nursing care device of the present embodiment thus obtained can operate as follows.

First, when the care lift 20 moves from the fixed starting position to the movement position at which the care receiver M1 is to be cared for, the driven wheel 21a moves through the wheel running area 11 separated from the power supply cable enclosing area 12 without any obstacle. Since the vehicle runs smoothly, the moving operation burden of the caregiver M2 is small.

When the nursing care lift 20 moves from the fixed starting position to the moving position at which care is to be performed, the nursing care lift 20 is returned from the moving position to the original position by the retraction force generated in the spiral expansion and contraction portion 41 of the power supply cable 40. Since the person is spontaneously pulled back to the home position, the evacuation operation burden of the caregiver M2 can be eliminated.

Further, when mooring to the indoor wall on the side where the care lift 20 is moved, the latch member 14 provided at the end of the traveling rail 10 can moor the traveling shuttle 21 of the care lift 20.

As described above, the overhead traveling type nursing care device of the present embodiment allows the caregiver M2 to easily reciprocate the nursing care lift 20, and at the same time, the load strength on the indoor ceiling C, the laying space, the construction burden and the device. The cost can be reduced, and the beauty of the nursing care space can be improved, and the effect is enormous.
