Description

  The present invention relates to a furniture overturn prevention device, and more particularly to an appliance used to support furniture using a wall surface of a house and prevent the furniture from falling over when an earthquake occurs.

  2. Description of the Related Art Conventionally, in order to prevent furniture from falling over when an earthquake occurs, there is a horizontal H-type or box-shaped support that is inserted between the top plate of the furniture and the ceiling of the house. When an earthquake occurs, the furniture is restrained through the support using the ceiling of the house as a fulcrum, thereby preventing the furniture from vibrating and preventing overturning.

  For the same purpose, use a wall or the like of a room where furniture is installed to hang a chain type or turn buckle type fall prevention device or wire rope between the wall and the top of the furniture. There are also things to pass.

  However, when the above-mentioned conventional furniture fall prevention tools such as the horizontal type H are used in a Japanese-style room, the Japanese-style ceiling is a suspended ceiling. It cannot float and prevent the furniture from falling. In addition, not only Japanese style ceilings, but many ceilings of houses are not much different from the hanging type, and there is a problem that such ceilings cannot be absolutely trusted in preventing furniture from falling. there were.

  On the other hand, it is thought that the chain type and turn buckle type fall prevention tool, or the fall prevention tool using the wire rope, once contributed to the furniture fall prevention, but when installing these, There is a problem that it is troublesome to adjust the length of the parts constituting each fall prevention tool or to connect individual parts, which is not practical. In addition, the turnbuckle-type overturn prevention device has a problem that the adjustment cost of the length is small and the mounting is inconvenient. Furthermore, after attaching these fall prevention tools, the turn buckle and the wire rope are exposed, so there is also a problem that the appearance is impaired.

  Therefore, the present invention has been made in view of the problems in the conventional furniture overturn prevention device, and has high reliability in preventing overturning of furniture, can be easily attached, and has an excellent appearance. The object is to provide furniture fall prevention tools.

  In order to achieve the above object, the present invention is a furniture overturn prevention device, comprising a male screw part, a rod-like member having an attachment part at one end, a female screw part screwed into the male screw part of the rod-like member, and one end And a cylindrical member having a mounting portion.

  Then, according to the furniture overturn prevention device according to the present invention, for example, the attachment portion at one end of the rod-like member is attached to the top plate of the furniture, and the male screw portion of the rod-like member and the female screw portion of the tubular member are screwed together. To prevent the furniture from falling by simply attaching the attachment portion at one end of the tubular member to a wall surface or the like while adjusting the distance between the attachment portion at one end of the rod-like member and the attachment portion at one end of the tubular member. Since the furniture can be fixed by the rod-like member and the cylindrical member after the attachment, the reliability is high and the attachment can be easily performed. Further, in the present invention, the turnbuckle and the wire rope are not exposed as in the prior art, and the cylindrical member and the male screw portion are mainly exposed, so that the extent to which the appearance of the furniture and its vicinity is impaired is small. I'll do it.

  In the furniture overturn prevention device, the attachment portion of the tubular member can be rotated with respect to a tubular main body integrated with the female screw portion. Thereby, even if the cylindrical member is rotated to adjust the length of the furniture overturn prevention tool, the attachment portion can maintain the state as it is regardless of the rotation of the cylindrical member. In addition, the furniture overturn prevention tool can be more easily attached.

  In the furniture overturn prevention device, an over-extension prevention mark can be provided in the vicinity of the free end portion of the male screw portion of the rod-shaped member. Accordingly, it is possible to prevent the male threaded portion of the rod-shaped member from coming off from the female threaded portion of the cylindrical member by excessively widening the interval between the rod-shaped member mounting portion and the cylindrical member mounting portion.

  In the furniture overturn prevention device, it can be connected to one mounting portion of the rod-shaped member or the cylindrical member, and can be connected to a bracket mounted on the top plate of the furniture and the other mounting portion of the rod-shaped member or the cylindrical member. A wall surface, a pillar, a duck, an upper rail, a long press or a bracket attached to the peripheral edge. The bracket is attached to the top plate of the furniture and the wall surface in advance, and both the mounting portions of the rod-shaped member and the cylindrical member are connected to each of the brackets with pins, so that the furniture overturn prevention device can be easily installed. Can be attached.

  As described above, according to the present invention, it is possible to provide a furniture overturn prevention device that is highly reliable in preventing furniture overturning, can be easily mounted, and has an excellent appearance.

  FIG. 1 shows an embodiment of a furniture overturn prevention device according to the present invention. The furniture overturn prevention device 1 is roughly composed of a rod-shaped member 2, a cylindrical member 3, and a bracket 4.

  The rod-shaped member 2 includes an attachment portion 2a having a through hole 2e, a male screw portion 2c integrated through the attachment portion 2a and the fixing pin 2b, and an excess portion formed in the vicinity of the free end portion of the male screw portion 2c. It consists of a groove portion 2d as an extension preventing mark. Red paint is applied to the bottom of the groove 2d.

  The cylindrical member 3 has a bearing portion 3e attached to one end of a cylindrical portion 3b and is integrated by a screw 3f. An attachment portion 3a having a through hole 3d is rotatably incorporated in the bearing portion 3e, and the attachment portion In 3a, movement in the axial direction is restricted by a C-type retaining ring 3j. With this configuration, when the attachment portion 3a is fixed to the bracket 4 by the pin 6, the attachment portion 3a does not rotate, and conversely, the cylindrical portion 3b can be rotated together with the bearing portion 3e.

  The cylindrical member 3 is integrated by a cylindrical portion 3b and a screw 3g, and a sleeve 3h in which a female screw portion 3c is screwed inside, and a knurled portion on the outer surface of the central portion in the axial direction of the cylindrical portion 3b. 3i.

  The bracket 4 includes a U-shaped main body 4a in plan view and a hole 4b formed in a side surface. Further, a screw 5 for fixing the bracket 4 to furniture or a wall surface and a pin 6 for connecting the bracket 4 and the mounting portion 3a of the cylindrical member 3 are also components of the furniture overturn prevention tool.

  Here, the length A of the exposed portion of the male screw portion 2c of the rod-like member 2 and the distance A 'from the free end of the male screw portion 2c to the right end portion of the mounting portion 3a of the cylindrical member 3 are configured to be equal. Further, the length B of the female screw portion 3c of the cylindrical member 3 and the length B 'from the free end of the male screw portion 2c of the rod-like member 2 to the groove portion 2d are configured to be equal. Thereby, the whole length of the furniture fall prevention tool 1 can be comprised compactly.

  Next, the usage method of the furniture fall prevention tool 1 which has the said structure is demonstrated, referring FIG.1 and FIG.2.

At this time, the top plate 10a and the wall surface 11 need to be attached to portions having high rigidity. Therefore, for example, the bracket 4B is attached to the surface of the wall surface 11 where the horizontal member 11a is located on the back side. Moreover, the furniture 10 is kept as close to the wall surface 11 as possible.

  Next, the pin 6 is inserted into the through hole 2e of the rod-like member 2 shown in FIG. 1 and the hole 4b of the bracket 4A attached to the top plate 10a so that the attachment portion 2a of the rod-like member 2 can be rotated to the bracket 4A. Install. Then, while rotating the knurled portion 3i of the cylindrical member 3 by hand, the furniture overturn prevention tool 1 is extended or shortened, and the mounting portion 3a of the cylindrical member 3 is brought close to the bracket 4B attached to the wall surface 11 to form a cylindrical shape. The pin 6 is inserted between the through hole 3d of the member 3 and the hole 4b of the bracket 4B so as to overlap each other. Thereafter, the knurled portion 3i of the cylindrical member 3 is manually rotated and tightened so that the mounting portion 2a of the rod-shaped member 2 and the mounting portion 3a of the cylindrical member 3 are close to each other, and an appropriate tensile force is applied. This completes the attachment of the furniture overturn prevention device 1.

  The pin 6 inserted into the hole 4b of the main body 4a is fitted into the two grooves formed in the pin 6 when the furniture overturn prevention device 1 applies a tensile force, so that the pin 6 Cannot be moved in the axial direction, and will not fall out after the furniture overturn prevention device 1 is assembled.

  If the groove 2d appears in the exposed portion of the male threaded portion 2c of the rod-like member 2 in the process of extending the furniture overturn preventing device 1, the tubular member is obtained when the furniture overturn preventing device 1 is further extended. Since the male screw portion 2c that can be screwed into the third female screw portion 3c is gradually shortened, the furniture overturn prevention device 1 is prevented from further extending.

  In the state shown in FIG. 2, the furniture overturn prevention tool 1 is interposed between the furniture 10 and the wall surface 11, so that the furniture 10 can be firmly fixed even when an earthquake occurs. Can be reliably prevented.
