DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for preventing furniture and other furniture from falling over in the event of an earthquake or the like.

[0002]

2. Description of the Related Art Conventionally, as an overturn prevention device of this type, for example, a plate made of a synthetic resin provided with a shaft provided with externally threaded externally threaded portions at both ends and a female threaded portion screwed to the externally threaded portions. Some have a shape contact member.

[0003] Such an apparatus is used as follows.
First, contact members are screwed to both ends of the shaft, respectively.
For example, one contact member is arranged on a beam on the ceiling, and the other contact member is arranged on the upper surface of a chest or the like in a posture facing each other.

When the shaft is grasped by hand without rotating the contact member and the shaft is rotated in either direction, the two contact members move in a direction away from each other or in a direction approaching each other. The shaft is rotated and adjusted so that the two abutting members abut on the opposing beams or the like.

[0005] Thus, since the apparatus is fixed between the beam and the upper surface of the chest or the like, even if the chest or the like is about to fall due to an earthquake, the tilting thereof can be prevented and the fall can be prevented.

[0006]

By the way, in order to reliably prevent the chest or the like from falling over, it is necessary to securely mount the above-mentioned device between the beam and the upper surface of the chest or the like. For this reason, it is preferable to keep the upper surfaces of the beam and the chest slightly pressed by the respective contact members.

In order to keep the beam or the like in a pressed state, the shaft must be rotated to some extent continuously after each contact member has contacted the beam and the upper surface of the chest or the like. However, after each abutting member abuts the upper surface of the beam and the chest, the force required to rotate the shaft gradually increases, and the hand holding the shaft slides, and the device is moved. There was a drawback that it could not be securely attached.

If the strength of the beam is low, stress may be concentrated on a portion where the contact member is in contact with the beam, and the beam may be damaged. On the other hand, if the contact area of the contact member with the beam is increased, such damage can be prevented, and the stability can be improved.

However, if the contact area of the contact member with the beam is increased, the thickness of the contact member must be increased from the viewpoint of strength, and the weight and cost increase.

Accordingly, an object of the present invention is to provide a device for preventing furniture and the like from tipping over, which can firmly fix furniture and the like in a stable state and can easily cope with a portion where strength is insufficient.

[0011]

According to the present invention, the furniture and the like 5 are interposed between the structural material 4 and the furniture 5 in the house to prevent the furniture and the like 5 from tipping over. Male screw portions C1 and C2 are formed at both ends, and a support shaft C having an insertion hole C3 formed at an intermediate portion into which a rotation-assisting rod-shaped member 1 can be inserted, and screwed into each of these male screw portions C1 and C2. A pair of cup-shaped contactor bodies A and B to which the nut 2 is fixed
It is composed of

A notch A for a reinforcing member into which an opening A2 of at least one contacting body A is fitted with a reinforcing member 3 for reinforcing a structural member 4 or furniture 5 contacting the corresponding contacting body A.
6, A6 may be formed. Further, the contacting members A and B are formed of a metal plate, and the central portions A1 and B1 are formed.
The nut fixing portions A3 and B3 in which the nut 2 is provided may be integrally molded.

[0013]

[Action] The contact device is screwed to both ends of the support shaft,
This is placed between the structural material of the house and the furniture. Then, the support shaft is rotated so as to press the abutment bodies against structural materials, furniture, and the like facing the abutment bodies.

At this time, when it is difficult to rotate the support shaft by hand alone, a rod-shaped member such as a screwdriver is inserted into the insertion hole of the support shaft and rotated.

If the strength of the structural material that comes into contact with the contactor body is insufficient, the contactor body is fitted with the reinforcing member fitted into the reinforcing member notch of the contactor body. To the structural material.

[0016]

Embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a perspective view showing the present apparatus, FIG. 2 is an exploded perspective view thereof, and FIG. 3 is a partial cross-sectional view showing an enlarged bottom portion of the contactor body.

This apparatus comprises two contacting members A and B and a support shaft C for attaching these contacting members A and B to both ends.

The support shaft C is obtained by cutting a metal pipe to a required length, and has male screw portions C1 and C2 which are screwed in opposite directions at both ends of the outer peripheral surface.

An insertion hole C3 having a diameter into which a rod-like member 1 for assisting rotation such as a driver can be inserted is formed in an intermediate portion of the support shaft C. By inserting the rod-shaped member 1 into the insertion hole C3 and rotating the support shaft C, a large torque can be generated with a small force. In addition, this insertion hole C3
You may form two or more in different positions as needed.

The abutting bodies A and B are made of metal formed in a cup shape whose diameter increases from the central portions A1 and B1 toward the openings A2 and B2. In this embodiment, a single metal plate is used. Is formed by deep drawing.

The central portions A1 and B1 are provided with hexagon nuts 2 and 2, respectively, which are screwed to the external thread portions C1 and C2 of the support shaft C. The portions A3 and B3 are formed so as to protrude, and through holes A4 and B4 through which the support shaft C is loosely inserted are formed in the protruding end surfaces.

The fixing of the hexagon nuts 2 and 2 to the nut fixing portions A3 and B3 is performed, for example, by fixing the nut fixing portions A3 and A3.
After inserting the hexagon nuts 2 and 2 into B3, this is performed by caulking, but it may be fixed by welding, an adhesive or the like.

At the openings A2 and B2 of the contacting devices A and B,
Flanges A5, B5 having a constant width are formed over the entire circumference, and these flanges A5, B5 are configured to abut on an upper surface of, for example, a beam or a chest.

Of the two contacting members A and B, notches A6 and A6 for reinforcing members are formed in the opening A2 of the contacting member A. Notches A6, A6 for these reinforcing members
Are formed at positions opposing each other in the opening A2, and the notches A6 for the reinforcing members are cut out so as to fit the reinforcing members 3 in a shape substantially matching the cross-sectional shape of the reinforcing members 3. ing.

Therefore, the reinforcing member 3 is notched by the notch A for the reinforcing member.
6, A6, the surface 3a of the reinforcing member 3 and the surface of the flange A5 become flush (FIGS. 1, 4).

Next, the operation of fixing furniture and the like using the overturn prevention device will be described mainly with reference to FIG. First, the contact members A and B are screwed into the male screw portions C1 and C2 of the support shaft C, respectively, and the contact member A is attached to the beam 4 and the chest 5
The contactor bodies B are arranged between the upper surfaces 5a such as at opposite positions.

Then, while holding the support shaft C by hand and keeping the contacting devices A and B from rotating, the supporting shaft C is rotated in either direction, and the two contacting devices A and B are rotated. Are brought into contact with the opposing beams 4 and the like.

After the contacting device A contacts the beam 4 or the like, a large force is required to rotate the support shaft C, and thereafter, it is impossible to rotate the support shaft C by hand. If so, the driver 1 or the like is inserted into the insertion hole C4 of the support shaft C and rotated. The driver 1 or the like may be inserted into the insertion hole C4 from the beginning and rotated.

If the strength of the beam 4 or the like is insufficient, the beam 4 bends or breaks at the contact portion with the contactor body A. Therefore, if necessary, if the reinforcing member 3 is fitted into the notch portions A6, A6 for the reinforcing member of the abutment body A, even if the strength of the beam 4 or the like is insufficient, stress concentrates there. Can be prevented.

The present invention is not limited to the above-described embodiment, and various modifications can be made within the scope of the invention.

Although a description has been given of a case where a pipe is machined as a support shaft, a solid shaft may be used in consideration of the diameter, material, weight, and the like of the support shaft.

In the above-described embodiment, the description has been given of the case where the abutment body A is fitted to only one end of the support shaft. However, the abutment body A is fitted to the other end of the support shaft. With
A furniture member or the like may be reinforced by fitting a reinforcement member into the notch for the reinforcement member.
