3 and a multi-stage slide cover 39 that covers the elevating mechanism 33
And is configured.

The lifting mechanism 33 is desirably capable of moving a large stroke in a small space because it is inserted between the lower surface of the article M and the floor F. As an example, a multi-stage hydraulic jack 33A is employed. I have.

The multi-stage hydraulic jack 33A shown in FIG.
This is a simplified illustration of a basic configuration that can be extended and contracted in multiple stages, and a hollow rod formed in a hollow shape and slidable in the cylinder case 34 in a cylinder case 34 having a lower mounting portion 32 attached to the lower end. 35, and a piston 36 slidably formed on the middle rod 35 and having an upper mounting portion 31 attached to the upper end thereof. The middle rod 35 and the piston 36 are each hydraulically driven. A hydraulic supply port 34a is disposed at the lower end of the cylinder case 34, and is configured so as to be connected with a hydraulic supply device as a control unit 5 disposed outside at a single touch via a hydraulic hose and a hydraulic fitting. .

The hydraulic jack 33A is raised by supplying oil, is locked at the rising end, and is unlocked to release the sink M (or M).
The oil supplied with the weight of 1) is configured to be collected in the hydraulic pressure supply device 5.

The multi-stage hydraulic jack 33A is not limited to the above configuration as long as it can move a set stroke, but may be three or more stages, or may have a basic configuration that can be expanded and contracted in multiple stages. If it is, a known one may be used.

The article support section 1 is attached to the upper mounting section 31.
0 base table 11 is attached,
Is attached to the bottom plate portion 40.

Further, the lifting mechanism 33 does not arrange the piston so as to extend in the vertical direction (the state shown in FIG. 3), but serves as a fulcrum for pivotally connecting the base of the hydraulic cylinder to the bottom plate with respect to the horizontal direction. Bottom plate 4 so that it can be inclined at an angle
0 may be attached. In this case, the distal end of the piston is attached to the article support unit 10 via a connection member that can be pivotally supported, and as the piston is extended by hydraulic pressure, the hydraulic cylinder rotates around the fulcrum in the vertical direction. What is necessary is just to be mounted as follows. If the hydraulic cylinders are arranged on both sides of the sink M (or M1) so that the pistons extend in opposite directions, the sink M (or M1) is perpendicular to the thrust generated in the axial direction of the piston. It will be raised by the thrust divided in the direction. In this hydraulic cylinder, a single-stage piston can be used instead of a multi-stage piston.

The lifting mechanism 33 is not limited to the above, but may be a mechanism using water pressure. For example, the elevating unit 30 is formed by disposing water in an elastic container formed of a high-pressure rubber material and disposing the elastic container in a case. The elastic container is expanded by supplying water from the water supply device, and the upper surface of the case is raised. In this case, for example, the upper case portion and the lower case portion are formed separately, and the upper case portion is attached to the article support portion 10 so as to be movable up and down. Then, simultaneous control is enabled by supplying a plurality of elevating units 30 with one water supply device.

The bottom plate portion 40 is formed such that the area corresponding to the floor surface is made as large as possible with respect to each of the lifting and lowering portions 30 subjected to the concentrated load so that no dent is formed on the floor surface. Is done. Further, the bottom plate portion 40 is formed in such a size that each side surface of the bottom plate portion 40 can be attached to a lower portion of a multi-stage slide cover 50 whose upper portion is attached to the article support portion 10 and is hung down. In this case, depending on the slide cover 50, it is desirable that the length be adjustable in the front-rear and left-right directions.

If the bottom surface of the elevating mechanism 33 is supported by a large area with respect to the floor surface, the bottom surface of the elevating mechanism 33 is directly brought into contact with the floor surface F without mounting the bottom plate portion 40. Is also good.

One form of the multi-stage slide cover 50 is as follows.
As shown in FIG. 3, an outer cover 51, a middle cover 52 and an inner cover 53 are juxtaposed so as to be superimposed in three stages, and the upper end of the outer cover 51 is attached to an angle member of the article support member 10; The portion is formed so as to be attached to the side surface of the bottom plate portion 40. The outer cover 51, the middle cover 52, and the inner cover 53 are slidably formed with respect to the opposing covers. When the article support portion 10 is at the lowest position, the outer cover 51, the middle cover 52, and the inner cover 53 are in a superposed state. As the article support portion 10 gradually rises, the outer cover 51 first rises, and the outer cover 51 When 51 reaches the position of the upper end of the middle cover 52,
The outer cover 51 is configured to lock the middle cover 52 and rise together.

Note that the slide cover 50 of the present embodiment is
Is composed of three steps, but the number of steps is set so that the slide cover 50 can close the gap formed between the sink M and the floor when the sink M (M1) reaches the rising end. Since it is set, it is not limited to three stages.

The slide cover 50 has a slide guide portion formed on an opposing surface of each cover.
A locking portion that can lock the outer cover 51 and the middle cover 52;
The configuration is not limited as long as the retaining portions for retaining the respective covers are at least arranged.

Further, the drain pipe attached below the water tank body of the sink M (M1) is formed by a bellows hose,
What is necessary is just to be attached so that expansion and contraction is possible to the trap pipe attached to the floor side, and it may be constituted so that the bellows hose may not be attached to or detached from the trap pipe when the sink M (M1) rises.

Next, the elevating device 1 constructed as described above
The operation of will be described.

First, the lifting body 3 is connected to an existing sink M (M1).
Sink M (M1) to be placed between the floor and the floor F
Is lifted by an elevator (not shown) to form a space between the sink M (M1) and the floor F. Each elevating body 3 is configured by assembling an article support portion 10, an elevating portion 30, and a bottom plate portion 40, and has a slide cover 50 attached to a side surface. In this state, the hydraulic pressure supply device 5 is not connected. The length in the front-rear direction and the left-right direction of the article support base 10 is adjusted in advance according to the dimensions of the sink M (M1).

Below the lower corners MC on both sides of the suspended sink M (M 1), the respective elevating bodies 3 are arranged, and inside the front angle member 15 and the rear angle member 17 of the article support portion 10. After the positioning of each of the elevating bodies 3 so that the lower corner MC of the sink M (M1) is fitted, the sink M (M1) is gradually lowered. The lower corner MC of the sink M (M1) is fitted into the front angle member 15 and the rear angle member 17, and the lower end surface of the sink M (M1) is supported by each of the support seats 26, 27, 28,
29, the sink M (M1) is lifted by each of the elevating bodies 3, 3
It will be supported by.

When the sink M (M1) is supported by the lifts 3, 3, the hydraulic supply device 5 is provided to each lift 3, 3 in order to set the sink M (M1) to an appropriate height. A piping is provided to the hydraulic supply port 34a of each hydraulic jack 33A via a hydraulic hose. Then, by operating the operation buttons connected to the pair of hydraulic pressure supply devices 5, 5, the pistons 36 of the hydraulic jacks 33A are simultaneously raised by driving the hydraulic pressure. With the rise of the piston 36, the outer cover 51 or the middle cover 52 of the slide cover 50 is raised.

At the time of this ascent, two elevating bodies 3,
Since the hydraulic pressure is simultaneously supplied to the sink 3 from the hydraulic pressure supply device 5, the left and right positions of the sink M (M1) can move while maintaining a substantially horizontal plane.

When the sink M (M1) reaches an appropriate height, the supply of the hydraulic pressure from the hydraulic supply device 5 is stopped and the hydraulic hose is removed from the hydraulic supply port 34a of the hydraulic jack 33A. Locked in the stop position,
The sink M (M1) is maintained at that position.

When the hydraulic hose is connected to the hydraulic supply port 34a again when descending the sink M (M1), the oil in the hydraulic jack 33A is recovered by the hydraulic supply device 5 by the weight of the sink M (M1). , Piston 36 and sink M (M1)
Can descend.

As described above, the lifting body 3 of the lifting device 1
When installing between the existing sink M (M1) and the floor F, the sink M (M1) must be modified so that the existing sink M (M1) simply needs to be lifted and lowered at that position. In addition, since the construction for opening the floor surface F is not required, the mounting work of the elevating device 1 can be performed with very easy work at a low cost.

The mounted lifting device 1 has a space for inserting a wheelchair, for example, since at least two or more lifting members 3 are respectively branched and arranged below both sides of the sink M (M1). Even when mounted on a wheelchair article, each elevating body 3 can be arranged without obstructing the insertion space of the wheelchair.

When the sink M (M1) is moved up and down,
Since the plurality of elevating bodies 3 are simultaneously moved up and down, the upper surface of the sink M (M1) can always maintain a substantially horizontal plane.

When the size of the existing sink M (M1) in the front-rear direction or the left-right direction differs depending on various manufacturers, the length of the article support portion 10 in the front-rear direction or the left-right direction is adjusted. , Sure sink M
The lower corner MC of (M1) can be supported.

Furthermore, when the sink M (M1) is raised and lowered, even if a gap is seen between the sink M (M1) and the floor surface F and the appearance is deteriorated, the gap between the article supporting member 10 and the bottom plate portion 40 can be reduced. Is provided with a multi-stage slide cover 50 that can be extended and retracted as the article support portion 10 moves up and down, so that the gap can always be covered, and the appearance does not deteriorate.

If the elevating mechanism 33 is constituted by a hydraulic unit, it is possible to stably support the heavy sink M (M1) and to connect the elevating body 3 to the hydraulic supply device 5 at the time of elevating. Since the hydraulic pressure can be supplied at the same time, it is easy to simultaneously control the elevating and lowering of the elevating bodies 3. Further, by removing the connection of the hydraulic supply device 5 after the elevating and lowering, the insertion space for a wheelchair is not obstructed.

The elevating device 1 is not limited to the above structure. For example, if the sink is formed in an L shape,
It is desirable that at least three elevating bodies 3 of the elevating device 1 are mounted.

The lifting mechanism is not limited to a hydraulic unit, as long as the lifting mechanism can save space and increase the stroke.
A mechanical configuration such as a mechanism for driving a ball screw by a motor or a mechanism using a link mechanism may be used.
