[Industrial applications]

 The present invention relates to a forced support, and more particularly to a forced support for preventing a large piece of furniture from tipping over in the event of a large vibration such as an earthquake.

[0002]

[Background of device]

 2. Description of the Related Art Conventionally, as a support tool for the above-mentioned purpose, there is known a support tool having an L-shaped angle fitting or a screw whose length can be adjusted. However, when using the angle fittings, screws, nails, and adhesives are used as the fastening method, which makes it difficult to attach the fittings to the intended position and also damages the furniture and the ceiling. In addition, even those that use screws to adjust the length are premised on expansion and contraction on only one side, so it takes time to perform the installation work, and the burden is concentrated on one screw. However, it was unreliable because it created a gap if the top and ceiling of the furniture were not perfectly parallel.

[0003]

[The purpose of the device]

 Therefore, the present invention has been made by paying attention to the actual situation and problems of the above-mentioned conventional technology, so that the workability is improved, the reliability is high due to the close fixing in the use state, and there is no fear of damaging furniture or the like. The purpose is to provide compulsory support equipment.

[0004]

[Means for Solving the Problems]

 In order to achieve this object, the forced support device according to the present invention has a straight cylindrical body with both end faces closed, and a screw which is reciprocal with respect to each other is provided at the center position on the axis of both end faces. It is characterized in that it is attached, and a pressing bearing is provided at the tip of each screw.

【Example】

 Next, an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a perspective view of a forced support device embodying the present invention, and FIG. 2 is a longitudinal sectional view of the same.

In these figures, reference numeral 1 denotes a straight cylindrical body, and openings at both ends of the cylindrical body 1 are fixedly closed by cap covers 2 and 2, respectively. Although the cylindrical body 1 is used in this embodiment, the cylindrical body 1 is not limited to a polygonal shape, a polygonal shape, or another irregular shape as long as the axial center is straight.

A through hole is formed substantially at the center of the cap covers 2 and 2 on or along the axis of the cylindrical body 1. The inner hole is aligned with the inner surface of the hole, and the nut 3, 3a is installed.

Screws 4 and 4a are screwed into the nuts 3 and 3a, respectively. The screws 4 and 4a are formed such that the directions of their threads are opposite to each other. Press bearings 5, 5a having the same shape are attached to the tips of the respective screws 4, 4a with their directions symmetrical to each other.

In this embodiment, the pressing bearings 5 and 5a have a substantially rectangular pyramid shape. However, it is needless to say that the shape is not limited to this shape. But it doesn't matter.

Further, the pressing bearings 5 and 5a are provided with cushion materials 6 and 6a such as rubber and sponge on the outer peripheral edge of the pressing contact surface with the object, and the outer surface portion is also made of the same material. The cushioning material 7, 7, 7a, 7a is applied. In this embodiment, the cushion members 7 and 7a are provided in two places on each of the pressing bearings 5 and 5a, but they can be freely provided without regard to this, and this form is also shown. However, it is not limited to this, and can be crossed or arranged in a dot shape.

The compulsory bearing according to this embodiment is configured as described above. Explaining the action and usage of the screw 4 and 4a, the screws 4 and 4a are rotated in directions opposite to each other by rotating the cylindrical body 1 about the axis, because of the relationship of the screw directions of the screws 4 and 4a. That is, it moves in the direction of expansion or contraction at the same pitch, and the position of each pressing bearing 5, 5a also moves in conjunction with the movement.

That is, the forced bearing is inserted into a gap between the furniture and the ceiling, and the cylindrical body 1 is rotated so that the outer surfaces (end surfaces) of the pressing bearings 5 and 5a come into contact with the surface of the furniture and the ceiling. By tightening until finally tightened, fixing with good adhesion can be obtained through the cushion materials 6, 6a, 7, 7a .... In addition, it can be used not only vertically but also laterally between furniture and walls.

[0013]

[Effect of device]

 The forced support device according to the present invention is constructed and operates as described above. Therefore, with simple operation, that is, the screw operation is performed twice for one rotation of the cylinder, the work can be done in a short time, and the usage condition is dense and highly reliable. Become. Also, since there is no vertical or horizontal direction restriction of the forced support itself, there is no need to be careful when mounting it.
