Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is to raise or lower the pool floor to change the depth of the pool, or to raise or lower the bathtub floor so that a wheelchair can be put into the bathtub.
The present invention relates to a lifting mechanism for a pool floor or a bathtub floor, which has a simple structure to be attached to the poolside or bathtub side.

[0002]

2. Description of the Related Art It is well known that the pool floor can be raised and lowered to change the depth of the pool, and the bathtub floor can be raised and lowered so that a person with a wheelchair can enter the pool floor. Many of the mechanisms are of the type that consists of an endless chain that is stored underground in the poolside, is vertically driven by a motor with a speed reducer, and connects the pool floor. Things are also known. As for the elevating mechanism of the bathtub floor, a type that is stored underground in the bathtub side is known.

[0003]

The above-described conventional lifting mechanism is arranged on both sides of the pool floor or the bathtub floor so as to support the pool floor or the bathtub floor from both sides, or The structure is complicated because it is supported by a large number of hydraulic cylinders. In addition, the conventional lifting mechanism cannot be installed in an existing pool or bathtub, or if it is attempted to be installed, the pool or bathtub must be significantly modified.

A first object of the present invention is to provide a pool floor or a bath floor elevating mechanism having a simple structure to be attached to a pool side or a bath side, and a second object is to provide an existing pool. It is intended to provide an elevating mechanism for a pool floor or bathtub floor that can be easily attached to a bathtub or bathtub.

[0005]

The invention according to claim 1 relates to an elevating mechanism for achieving the first object, which is mounted on the poolside or the bathtub side or above the basement, and has a length on one side of the pool floor or the bathtub floor. It is characterized in that it is connected to the side to support the pool floor or the bathtub floor in a cantilever shape. According to the present invention, the pool floor or the bathtub floor is supported only on one long side, and the lifting mechanism is provided only on one side of the pool side or the bathtub side, so that the structure is simple.

The lifting mechanism of the present invention comprises, for example, a winding cylinder that is driven to rotate by a motor with a speed reducer, and a line such as a chain or a wire that connects the winding cylinder to the pool floor or the bathtub floor. One that raises or lowers the pool floor or bathtub floor by winding or rewinding a strip, or an endless chain or wire that connects the pool floor or bathtub floor by circulating the vertical circulation by a motor with a reducer. It is possible to use, for example, a rope which is configured to raise and lower the pool floor or the bathtub floor by circulating the rope.

Any of the above-described lifting mechanisms can be installed when a pool or bathtub is newly installed, or can be installed in an existing pool or bathtub. When installing the lifting mechanism in the basement of the poolside or bathtub side, if you try to install it in the existing pool or bathtub, it will be necessary to renovate the poolside or bathtub side significantly, but the lifting mechanism should be installed on the poolside or bathtub side. Once installed, it will be possible to install easily without major modifications to the poolside or bathtub side.

The pool floor to which the present invention is applied has a width narrower than the pool width, for example, about half of the pool width. However, in a pool with a narrow width such as a pool for rehabilitation, the pool width is Can be about the same. Even in the case of a bathtub, the width of the bathtub floor can be set to be approximately the same as that of the bathtub.

The invention according to claim 2 relates to an elevating mechanism for supporting a pool floor or a bathtub floor in a cantilever manner, and the elevating mechanism of the invention according to claim 1 extends along the side wall of the pool or bathtub. It is characterized in that it has a vertically installed rail and a slider connected to a rope such as a chain or a wire so as to be slidable only up and down on the rail and fixed to a pool floor or a bathtub floor.

The invention according to claim 3 relates to a lifting mechanism for achieving the second object, which is mounted on a poolside or a bathtub side and connected to a long side of the pool floor or one side of the bathtub floor. In a lifting mechanism for a pool floor or bathtub floor that supports the floor or bathtub floor in a cantilevered manner,
A motor installed on the poolside or the bathtub side, a shaft horizontally supported on the poolside or the bathtub side, and rotationally driven by the motor, and an appropriate space on the poolside or the bathtub side along the side. And a winding drum driven by the shaft, and a chain such as a chain or a wire that is connected to the winding drum and supports the pool floor or the bathtub floor. The winding drum winds or unwinds the rope. It is characterized in that the pool floor or the bathtub floor is moved up and down.

According to a fourth aspect of the invention, instead of the winding drum of the third aspect of the invention, an endless chain, a wire or the like, which is circularly driven in the vertical direction by a shaft, is arranged, and each line is provided. It is characterized by connecting a pool floor or a bathtub floor.

According to the third and fourth aspects of the present invention, the motor and the shaft are simply installed on the poolside or the bathtub side, and the existing pool or bathtub is not significantly modified on the poolside or the bathtub side. It is possible to mount the motor, and it is not necessary to provide a motor as a drive source for each winding cylinder or for each endless rope, and it is possible to simplify the structure by using one motor as a drive source. It is desirable that the cord of each of the above inventions be covered so that the user of the pool or bathtub cannot touch it.

DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 shows a pool for rehabilitation. A motor 1 with a speed reducer is mounted on a base B mounted on the pool side, and a shaft rotatably driven by the motor 1. 2 is horizontally supported, and sprockets 3 are attached to both ends of the shaft 2. And on each sprocket 3, as shown in FIG.
A chain 6 connected to a slider 5 is hung between the sprocket 4 and a sprocket 4 pivotally supported on the bottom of the pool under the sprocket 3, and the chain 6 is circulated by the drive of the sprocket 3 so that the slider 5 moves up and down. There is.

As shown in FIG. 3, concave rails 7 are arranged facing each other on both sides of the hanging chain 6, and rollers 8 axially supported on the upper and lower sides of the slider 5 are fitted on the rail 7. Roller 8 rolling on rail 7 and slider 5
Can only be moved up and down along the rail 7.

The slider 5 also has a pool floor 11 at the lower end.
Is stuck. According to this embodiment, the slider 5
The rollers 8 provided on the upper, lower, left, and right sides of the slider 5 are fitted to the rails 7 to prevent the slider 5 from tilting in the left-right direction shown in FIG. It is supported like a cantilever on the sides.
Further, the pool floor 11 supported at two places can be provided with the shaft 2 which is rotationally driven by the motor 1 so that the motor as a drive source can be unified and the structure can be simplified. It is possible to install it on an existing pool without significantly modifying the pool side by mounting the rail and attaching the rail 7 to the side wall of the pool.

[0016]

According to the first aspect of the present invention, the pool floor or the bathtub floor is supported in a cantilever shape, so that the support mechanism is different from the conventional one that supports the pool floor or the bathtub floor from both sides. Since only one side needs to be provided, the structure is simple. According to the lifting mechanism of the invention according to claim 2, the pool floor or the bathtub floor can be supported in a cantilever shape.

According to the third and fourth aspects of the present invention, the lifting mechanism for the pool floor or bathtub floor can be easily attached to the existing pool or bathtub without making any major modification to the poolside or bathtub side. At the same time, it is possible to simplify the structure by using only one motor as a drive source.
