Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention mainly relates to a simple leveling support device for supporting and leveling a bathtub or the like when the bathtub or the like is installed on a foundation.

[Prior Art] Conventionally, when a bathtub is installed on a foundation, a block or the like is generally inserted between the bathtub and the foundation to support the bathtub and adjust the height and level of the bathtub.

[Problems to be solved by the invention] According to the above-mentioned conventional height adjustment and leveling means for bathtubs, the work is troublesome, and moreover, bathtubs are usually installed against walls, so the work space is small. This makes the work even more troublesome, and furthermore, it is extremely difficult to adjust the height to the desired height or to accurately set the level.

In view of the above points, the present invention provides a leveling support that supports a bathtub, allows for easy and accurate height adjustment and leveling, and can also be used for leveling other than bathtubs. .

[Means for Solving the Problems] In order to solve the above problems, the present invention has a cylinder that is closed at one end and open at the other end, and is in close contact with the inner wall of the cylinder to receive fluid pressure sent into the cylinder. A disc-shaped sliding body that moves, a disc-shaped or ring-shaped ratchet that is pushed and moved by the movement of the sliding body, and a cylinder opening that is also pushed and moved via the ratchet by the movement of the sliding body. It is fitted with a protruding rod protruding from the axially movable
In the case of the disk-shaped or ring-shaped ratchet, its outer diameter is smaller than the inner diameter of the cylinder, and the length between the end of one surface and the end of the other surface diagonally passing through the axis is the inner diameter of the cylinder. A disk or ring larger than the above, with a protrusion provided on a part of the outer peripheral edge side of the protruding rod side of the disk or ring, and this protrusion is brought into contact with the protruding rod. It was adopted.

[Function] For example, when supporting a bathtub and adjusting its height or leveling, place the top of the closed end of the cylinder on the bottom of the bathtub at the four corners between the bathtub and the foundation, and place the open end of the cylinder on the foundation surface. Insert it so that it hits the When fluid such as oil is pumped into this cylinder, the sliding body is pushed by the fluid pressure and moves toward the opening side of the cylinder.
The movement of the sliding body pushes the protruding rod in the same direction through the ratchet, so that the protruding rod projects from the opening of the cylinder, and this protrusion of the protruding rod pushes up the bathtub. The height of the bathtub can be adjusted and leveled by means of a protruding rod that protrudes by pumping fluid into the cylinder. When the pressure of the fluid is stopped when the bathtub reaches a predetermined height, the weight of the bathtub is applied to the cylinder, and the protruding rod that partially protrudes from the cylinder tries to return into the cylinder, and the force of this return is Since the latch concentrates on the protrusion provided on a part of the outer peripheral edge of the surface of the protruding rod side of the ratchet, the ratchet is inclined within the cylinder, and the inclined edge bites into the inner wall of the cylinder, resulting in the protruding rod being is prevented from returning, and the bathtub is held at the adjusted height.

[Examples] Hereinafter, the present invention will be described in detail based on examples shown in the drawings, but the present invention is not limited to the examples.

In the drawings, 1 is a cylinder with one end closed and the other end open, and this cylinder 1 has a cylindrical body 2,
It consists of a closing cap 3 screwed onto an opening at one end of a cylindrical body 2. The closed cap 3 has a communication hole 4 formed in its side surface that communicates the inside and outside of the cylinder 1 with one end open and the other end opened into the cylindrical body 2. Reference numeral 5 denotes a disc-shaped sliding body fitted into the cylinder 1 in close contact with the inner wall of the cylinder 1 so as to be movable in the axial direction. It is designed to move in the direction of the opening. 6 is a seal ring fitted around the outer periphery of the sliding body 5.

A ratchet 7 is fitted into the cylinder 1 so as to be movable in the axial direction, and is pushed by the movement of the sliding body 5 to move in the same direction. 8
Similarly, a cylindrical protruding rod is fitted into the cylinder 1 so as to be movable in the axial direction, and when the sliding body 5 moves, it moves in the same direction, that is, through the ratchet 7, into the cylinder 1.
The cylinder 1 is pushed and moved in the opening direction of the cylinder 1, so that a part of the cylinder 1 protrudes from the opening 9 of the cylinder 1.

The ratchet 7 has a circular outer periphery, the outer peripheral ends of one side and the other side are formed into corners, the outer diameter L ₁ is smaller than the inner diameter L ₂ of the cylinder 1, and the axis is centered. This is a ring in which the length L ₃ between the ends of one side and the other side on the diagonal line is larger than the inner diameter L ₂ of the cylinder 1, and the entire surface of this ring on the sliding body 5 side is the sliding body abutting surface. The surface located on the side of the protruding rod 8 is provided with a projection 10 on a part of its outer peripheral edge.
0 is in contact with the protruding rod 8.

11 is a plug screwed into the communication hole 4; 12 is a socket detachably connected to the plug 11;
3 is a communication hole 4 via the socket 12 and plug 11.
This is a pipe that sends fluid from the cylinder 1 into the cylinder 1.

Next, the operation of the present invention will be explained.

When fluid such as oil is fed into the cylinder 1 from the pipe 13, the sliding body 5 inside the cylinder 1 is pushed and moved in the direction of the opening 9 of the cylinder 1 by this fluid pressure, and the movement of the sliding body 5 causes the ratchet 7 to move. The protruding rod 8 is pushed out in the same direction through the cylinder 1, and a portion thereof protrudes from the opening 9 of the cylinder 1 (FIG. 3).

Next, the pressure feeding of the fluid into the cylinder 1 is stopped, the sliding body 5 is released from the fluid pressure, and the protruding rod 8, which partially protrudes from the opening 9 of the cylinder 1, is pressed inward to the cylinder 1. , this pressing force of the protruding rod 8 is concentrated on the protrusion 10 provided on the outer peripheral edge side of the surface facing the protruding rod 8 side of the ratchet 7, and the ratchet 7 is inclined within the cylinder 1, causing the ratchet 7 to tilt.
The outer circumferential end in the inclined direction of the surface bites into the inner wall of the cylinder 1, and the return of the protruding rod 8 into the cylinder 1 is prevented (FIG. 4).

FIG. 5 shows an example in which the present invention is used for leveling a bathtub. In this use, the cylinder 1 is provided at the four corners between the bottom surface of the bathtub 14 and the foundation 15 so that the top surface of the closed part of the cylinder 1 is in contact with the bottom surface of the bathtub 14 and the opening part 9 is in contact with the surface of the foundation 15, respectively. A pipe 13 for sending fluid is connected to the communication hole 4 of the cylinder 1 through a plug 11 and a socket 12.

Next, fluid is pumped into each cylinder 1 from the pipe 13, and the protruding rod 8 is made to protrude from the opening 9 of the cylinder 1. In this way, the protruding rod 8 is made to protrude from the cylinder 1, the bathtub 14 is pushed up, and the height of the bathtub 14 is adjusted and leveled. When the bathtub 14 reaches a predetermined height, the pressure feeding of the fluid is stopped and the sliding body 5 is released from the fluid pressure.
is applied, and a force is applied to the protruding rod 8 protruding from the cylinder 1 to try to return into the cylinder 1, and this force causes the ratchet 7 to tilt and bite into the inner wall of the cylinder 1, preventing the protruding rod 8 from returning. Thus, the bathtub 14 is held on the foundation 15 at the adjusted height.

When the height adjustment and leveling are completed in this way, the socket 12 is separated from the plug 11.

[Effects of the invention] As described above, according to the invention, by force-feeding fluid into the cylinder, it is possible to level the bathtub, etc. with the protruding rod protruding from the cylinder, and then stop feeding the fluid. By doing so, the ratchet prevents the protruding rod from returning and the bathtub can be held at the same level, making it easy to operate and level the bathtub. This makes it possible to perform the work easily even if the work space is small, making it especially suitable as a leveling support for hemmed items that are hemmed in narrow spaces such as bathtubs. Furthermore, since the structure is simple, it is easy to manufacture and can be obtained at low cost.
