Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a furniture fall prevention device.

[0002]

[Prior art]

 For example, there are fall prevention devices proposed in Japanese Utility Model Publication No. 58-152151 and Japanese Utility Model Publication No. 60-56349. The former is a combination of the upward and downward U-shaped lower left and right pipes and the downward U-shaped front and rear upper pipes. The upper and lower ends of the upper and lower pipes are connected so that they can move up and down and are fixed, and they are interposed between the top plate of furniture and the ceiling of the room to prevent them from falling. By the way, some furniture has a structure in which the top plate is made of a thin plate material and has a weak strength, and when the former device is used for such furniture, it is especially likely that external force due to shaking such as an earthquake will occur. There is a structural problem in that it loses its top plate and loses its original function of preventing it from falling. In addition, the upper and lower pipes are exposed and directly viewed, so the appearance is poor and harmony with furniture and room cannot be expected.

On the other hand, the latter is a hinge type, and is used by fastening it with screws or the like over the top plate portion of furniture and the wall of the room. Therefore, if the wall is made of concrete, there is a complaint that the installation is large and lacks versatility, and the hinge type is exposed and directly looked at, and the appearance impression is poor. Harmony with furniture and rooms cannot be expected.

[Problems to be solved by the device]

 The problem to be solved is to prevent falling of furniture that can be easily set in a fall prevention state, has excellent fall prevention strength, and can be designed as a part of furniture to blend into it to achieve harmony with furniture and parts. To provide a device.

[0005]

[Means for Solving the Problems]

 In order to solve the above-mentioned problems, an outer frame having the same contour shape as the top plate of the furniture main body is fixed with a fixing tool, and an inner frame similar in shape to the outer frame is vertically placed inside the outer frame. It is movably arranged, a hard protective plate is attached at an appropriate place on the lower surface of the inner frame, and a hard support is provided on the top plate portion directly below the hard protective plate, and a female screw hole of the support is provided. A bolt member is screwed to the lower end of the bolt member, the lower end of which can contact the lower surface of the protective plate, and the lower end of the bolt member protrudes from the hole of the top plate portion into the storage portion in the furniture main body. The furniture main body provided with the fall prevention device of the present invention may be a new one or an existing one and is not limited. The furniture body may be a one-box type or a plurality of boxes.

[0006]

[Action]

 By turning the bolt member from inside the storage part and pushing up the inner frame until its upper surface abuts on the ceiling of the room, the furniture can be easily set in the fall prevention state. The top, front, back, left, and right of the inner frame are equally in contact with the ceiling of the room, and this inner frame is inside the outer frame integrated with the top plate of the furniture and is prevented from moving in the front, rear, left, and right horizontal directions. Therefore, the contact state with the ceiling is maintained and the fall prevention strength is high. Furthermore, the outer frame has the same shape as the contour shape of the top plate of the furniture, and the inner frame inside this outer frame has a similar shape to the outer frame, so the outer frame and the inner frame are designed in harmony with the furniture body and the room. To do. In addition, a hard protective plate is attached to the lower surface of the inner frame, and a bolt member is screwed into the female screw hole of the rigid support, and the inner frame is pushed up by the bolt member through this protective plate. Therefore, it is structurally high in strength.

[0007]

【Example】

 1 and 2 exemplify furniture equipped with a fall prevention device according to the present invention, and a furniture body 1 has a three-tiered structure including an upper stage part 2, a middle stage part 3 and a lower stage part 4. The upper step portion 2 and the middle step portion 3 are fixed by being embedded in the upper surface portion 3a of the middle step portion 3 by passing the connecting bolt 5 through the hole 2b in the bottom surface portion 2a of the upper step portion 2 from the inside of the storage portion 2c to the lower side. It is integrally connected by screwing on the Onime nut 3b. Similarly, the middle step portion 3 and the lower step portion 4 are fixed by being embedded in the bottom surface portion 3c of the middle step portion 3 by passing the connecting bolt 6 through the hole portion 4b in the upper surface portion 4a of the lower step portion 4 from the inside of the storage portion 4c to the upper side. It is integrally connected by screwing it to the ogre nut 3d, and the upper, middle and lower steps 2, 3 and 4 are integrally connected and fixed.

An outer frame 7 having the same shape as the contour shape of the top plate portion 2d and having an appropriate height is attached to the top plate portion 2d of the upper step portion 2 with a fixture 8 such as a screw. Inside the outer frame 7, an inner frame 9 having a shape similar to that of the outer frame and slightly smaller and having an appropriate height is disposed so as to be vertically movable, and the inner surface of the outer frame 7 between the inner frame 9 and the inner frame 9 is also movable. A sliding member 10 such as a threshold sliding member is attached to this.

A protective plate 11 such as a hard plastic plate or a metal plate is attached near the left and right ends of the lower surface 9a of the front and rear rods of the inner frame 9 by a fixture 12 such as a screw, and the protective plate is attached. 11 A support 13 made of hard plastic or metal is provided on the top plate portion 2d immediately below by fixing it with a fixing tool 15 such as a screw, and a bolt member 16 is screwed into a female screw hole 14 formed at the center of the support 13. I am doing it. A scratch-proof member 18 such as a cork sheet is attached to the upper surface 9b of the inner frame 9.

The length of the bolt member 16 is such that the upper end of the bolt abuts the lower surface of the protective plate 11 and the lower end of the bolt projects from the hole 2e of the top plate 2d into the storage 2c in the furniture body 1. A dish-shaped support metal fitting 17 is pivotally attached to the upper end of the bolt so that it comes into contact with the protective plate 11 via the support metal fitting 17.

With this, by rotating the bolt member 16 from inside the storage section 2c and pushing up the inner frame 9 until its upper surface comes into contact with the ceiling of the room, the furniture can be easily set in the fall-prevention state. The upper, middle and lower steps 2, 3 and 4 are integrally connected and fixed, and the structure is strong, and the connecting bolts 5 and 6 can be removed to be easily separated. Since the sliding member 10 on the inner surface of the outer frame 7 guides the vertical movement of the inner frame 9, the outer surface of the inner frame 9 is not scratched and the decorative surface can be protected. Since the scratchproof member 18 is attached to the upper surface 9b of the inner frame 9 so as to be in contact with the ceiling of the building, the ceiling is not damaged.

Further, although not shown, when the furniture main body 1 is an existing one, an appropriate decorative member is attached to the outer surfaces of the outer frame 7 and the inner frame 9 to achieve harmony with the furniture main body 1. You can do so.
