Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial field of application> The present invention relates to a moving wall fixing device capable of releasing a locked state with one touch.

<Prior Art> In general, in an exhibition hall, a conference room, a wedding hall, etc. for arts, it is preferable to be able to change the partition of the room which is the venue depending on the type, form, atmosphere, etc. The moving wall is the result of such a request. And hanging such a moving wall from the ceiling,
In addition, in order to move it, a hanger rail is arranged on the ceiling, but it is as if the hanger rail can move the moving wall in any position or direction. It is arranged so that it crosses like a grid.

By the way, such a moving wall has a very large weight,
Regardless of the time of movement, if there is no support from below when stopped, all the load will be applied to the hanger rail, and as a result, it will be deformed unless the hanger rail is significantly strengthened, and the suspended moving wall will sway and stabilize. It lacks sex.

Therefore, conventionally, it is used when the moving wall is stopped,
A rotary jack was disposed below the moving wall, and the legs of the jack were rotated to expand and contract to fix the jack on the floor or support the moving wall. However, according to this, even when lowering the jack,
Or, conversely, even when raising it upwards, he had to rotate it, and he was forced to take troublesome work. As you can see especially when considering where to perform this operation, it is difficult to operate because it is a posture that humans bend down and suffer because it is done near the floor, so it is necessary to retract the jack for that. I did not do enough, so when I moved this moving wall,
There was an accident such as rubbing the floor at the bottom of this jack (the floor is often reluctantly finished with a slightly wavy surface).

<Means for Solving Problems> Therefore, in order to solve the above-mentioned problems, the moving wall fixing device according to the present invention has an operating body in which a screw rod is planted in the center and a lower surface of the operating body. A base material that is rotatable with respect to the body is arranged, and the screw rod is inserted into a cylindrical body that is fixed to the lower surface of the moving wall in the vertical direction, and the screw groove pitch of the screw rod is provided below the cylindrical body. A through hole is also formed together, an engaging element is engaged with the through hole so that the engaging element can move in and out, and a through hole is formed in the center to form a retracting recess of the engaging element on the inner wall surface of the hole. A rotatable control annulus is arranged at the position of the engaging element, a cylindrical cap is slidably fitted on the upper part of the cylindrical body, and a spring is interposed between the cylindrical cap and the cylindrical body. Moreover, the upper end of the tubular cap body is connected to the screw rod to lower the base material. Although the operating body is sometimes rotated, when the operating body is raised, the base material can be instantly raised by slightly rotating the control ring.

<Embodiment> Next, an embodiment of the moving wall fixing device according to the present invention will be described with reference to the drawings. 1 is an operating body in which a screw rod 2 is planted in the center, and 3 is a lower surface of the operating body 1. The base material is rotatably arranged with respect to the operating body 1. Reference numeral 4 denotes a cylindrical body that is fixed to the lower surface of the moving wall W in the vertical direction. To fix the cylindrical body 4 to the moving wall W, a mounting plate 5 is used. The threaded rod 2 is arranged by being inserted into the tubular body 4, and a through hole 6 is formed below the tubular body 4 in accordance with the thread groove pitch of the threaded rod 2.
That is, this through hole 6 is formed along a spiral locus. Reference numeral 7 denotes an engaging element that is engaged with the through hole 6 in a protruding / retracting state. Reference numeral 8 is a control ring body having a hole 9 having an inner diameter slightly larger than the outer diameter of the cylindrical body 4 formed in the center thereof.
A recess 10 is formed for retracting. This recess 10
After all, since it is for retracting all the engaging elements 7 at the same time, it must match the number of engaging elements 7. The control ring 8 is rotatably arranged with respect to the cylinder 4. 11 is this control ring 8
However, since the handle 11 is used to rotate the control ring body 8, the control ring body 8 is not provided with the handle 11 as described above and is provided with a recess. Alternatively, a driver may be inserted into this recess for operation. 12 covers the upper part of the cylindrical body 4 and
It is a tubular cap body that is slidable with respect to, and the upper end of the cap body 12 is connected to the upper end of the screw rod 2, and inside the cap body 12, the tubular body 4 and the cap body 12 are An elastic spring 13 is interposed between them. Incidentally, 14 is a stopper for preventing the control ring 8 from rotating excessively.

<Operation> When the moving wall W is fixed to the floor surface, the operation body 1
The base material 3, which is connected to the screw rod 2 by means of, must be brought into contact with the floor surface at the eyes. For this purpose, first, the operating body 1 is rotated. However, when the operating body 1 is rotated in this manner, the control ring 8 is rotated and the engaging element 7 engaged with the through hole 6 formed in the lower portion of the tubular body 4 is the control ring 8. It is arranged so as not to be the recess 10. In this state, the thread groove of the threaded rod 2 acts as a female screw, and the engaging element 7 acts as a male thread. In order to obtain such a state, the control ring 8 is rotated, and the control ring 8 is rotated.
The engaging member 7 is pressed inward by the inner wall surface of the hole 9 which is not the recessed portion 10, and the engaging member 7 is pushed out from the through hole 6 of the cylindrical body 4 toward the inside of the cylindrical body 4, so that the engaging bar 7 is screwed 2 It is engaged with the screw groove of. In this way, if the operating body 1 is rotated as described above, the screw rod 2 and the control ring body 8 are integrated through the engaging element 7, and the control ring body 8 is also integrated.
By bringing the handle 11 into contact with the stopper 14,
Since further rotation is blocked, the cylinder 4 and the control ring 8
Therefore, the screw rod 2 is lowered while maintaining the positional relationship with the. Further, although the tubular cap body 12 also rotates by rotating the operating body 1 as described above,
I don't care. On the other hand, as the screw rod 2 descends, the cap body 12 connected to the screw rod 2 is also pulled down along the tubular body 4, and the spring 13 causes the cap body 12 to move.
It will be in a state of contracting by descending. That is, the screw rod 2 is lowered against the elastic force of the spring 13. Then, when the operation body 1 is stopped from rotating when the operation body 1 is lowered by the required length, the base material 3 comes into firm contact with the floor surface, so that the moving wall W is supported from below.

Next, when raising the screw rod 2 from such a state,
Needless to say, the operating body 1 may be rotated in the opposite direction to that described above, but since the feature of the present invention lies in that this operation is performed with one touch, these are described below. That is, holding the handle 11 of the control ring body 8, the control ring body 8 is rotated in either direction. Then, the engaging element 7 existing at a position other than the concave portion 10 of the hole 9 of the control ring body 8 jumps into the concave portion 10 because the constraint is released, whereby the engagement between the engaging element 7 and the screw rod 2 is loosened (or released). Then, the cap body 12 rises due to the elastic force of the spring 13, and the screw rod 2 connected to the cap body 12 and the operating body 1 and the base material 3 connected to the screw rod 2 rise instantaneously. . The limit of the rise of the operating body 1 and the base material 3 in this manner is the position where the operating body 1 comes into close contact with the lower end of the tubular body 4.

<Effects of the Invention> As described above, according to the moving wall fixing device of the present invention, the operating body in which the screw rod is planted in the center and the lower surface of the operating body, which is rotatable with respect to the operating body. The screw rod is inserted into a cylindrical body that is fixed to the lower surface of the moving wall in the vertical direction, and a through hole is formed below the cylindrical body in accordance with the screw groove pitch of the screw rod. , The rotatable control ring body which engages the engaging element so as to be able to move in and out of the through hole, has a hole penetrating in the center thereof, and forms a retracting recess for the engaging element on the inner wall surface of the hole. It is arranged according to the mating position, and a cylindrical cap body is slidably covered on the upper part of the cylindrical body, and a spring is interposed between the cylindrical cap body and the upper end of the cylindrical cap body. Since it is connected to the screw rod, even if the base material is locked in close contact with the floor Has an effect that it can be lifted in an instant by releasing only by a slight rotation of the control ring.
