Description

[Detailed Description of the Invention] The present invention relates to a furniture toppling prevention metal fitting that can be attached between upper furniture and lower furniture to prevent the upper furniture from overturning and absorb vibrations of the upper furniture.

BACKGROUND ART Conventionally, furniture installed indoors has been provided with a large number of fall prevention metal fittings of various shapes and structures. Specifically, in the case of Japanese dance, etc., the upper and lower parts are divided into upper and lower parts, and the thing to ensure that the upper and lower parts are fixed is to attach the upper metal fitting A to the upper furniture Fa and the lower part, as shown in Figure 12. Metal fittings b
There is a type of furniture in which the upper and lower fittings a and b are each fixed to a lower furniture Fb using a bolt c that can be moved up and down. This was easy to dislodge due to vibrations such as earthquakes, and had the drawbacks of accidents such as the upper furniture Fa, or even the entire furniture falling over, and the bolts being lost. Furthermore, there are some models in which the bolt c is provided with a leaf spring, but even with this, the upper metal fitting a and the bolt c are separate and have the disadvantage that they can be lost in some cases.

Therefore, as a result of intensive research, the applicant found that U.
A through hole is bored in the U-shaped part of the upper metal fitting with mounting pieces on both sides of the shaped part, and a vertically elongated lift locking plate has a bent edge at the upper end and a folded edge at the lower end. A hole is bored, a rivet is provided between the elongated hole of the elevating locking plate and the through hole of the U-shaped portion of the upper metal fitting, and a leaf spring is springed at the rear end of the rivet, so that the elevating and lowering is always carried out. One has a locking plate that is in close contact with the upper metal fitting and can be raised and lowered, and the other has a lower metal fitting with mounting pieces provided on both sides of the U-shaped part. The folded edge of the lift locking plate can be appropriately locked to the lower end of the inclined surface side of the U-shaped portion of the lower metal fitting, so that it can be attached to the upper part. It is installed between the metal fittings and the lower furniture, prevents the upper furniture from falling, and absorbs the vibrations of the upper furniture to maintain the fixed state, making it safe and eliminating the above-mentioned drawbacks.

The structure will be explained with reference to the drawings.

Reference numeral A denotes an upper metal fitting, in which vertical mounting pieces 2, 2 are integrally formed outward from both ends of a U-shaped part 1 having a U-shaped cross section when viewed from above, and the overall shape has a cross-sectional shape when viewed from above. It has a shape. A through hole 3 is bored approximately in the center of the surface side 1a of the U-shaped portion 1.
At the lower end of the surface side 1a, a protruding piece 1b is bent toward the surface side and is cut and raised as necessary. 4
is a lifting/lowering locking plate, which is vertically elongated as a whole.
A substantially horizontal bent edge 4a is formed on the rear side of the upper end of the lifting locking plate 4, and a folded edge 4b is bent on the rear side of the lower end thereof, and a vertically elongated hole 5 is formed approximately in the center of the lifting locking plate 4. It is perforated. U of the upper metal fitting A
The elevating and lowering locking plate 4 is provided on the surface side of the surface side 1a of the character-shaped portion 1 so as to be movable up and down while being constantly resilient. That is, a rivet 6 with a head only on the surface side is inserted between the vertical hole 5 of the lifting locking plate 4 and the through hole 3 of the surface side 1a of the U-shaped portion 1 of the upper metal fitting A. The rivet 6 is fixed to the rear end of the plate spring 7 at approximately the center thereof by caulking or the like, and the elevating/lowering locking plate 4 is always brought into close contact with the upper metal fitting A by the spring of the plate spring 7. It is configured to be able to rise and fall within a length range of 5.

Reference numeral B denotes a lower metal fitting, in which vertical mounting pieces 9, 9 are integrally formed outward from both ends of a U-shaped portion 8 having a U-shaped cross section when viewed from above, and the overall cross-sectional shape is a hat when viewed from above. It has a shape. The surface inclined side 8a of the U-shaped portion 8 is formed so as to gradually widen toward the surface side as it goes downward. In the example,
As shown in FIGS. 4 and 5, the surface inclined side 8a is inclined up to the middle between the upper and lower sides, and the lower side thereof is formed vertically.

Surface slope side 8a of the U-shaped portion 8 of the lower metal fitting B
The folded edge 4b of the elevation locking plate 4 can be appropriately locked at the lower end of the lift locking plate 4. Also, Figure 1,
As shown in FIG. 4, etc., a notch 8b corresponding to the width of the lifting locking plate 4 is often formed at the lower end of the surface inclined side 8a of the lower metal fitting B. After the lower end of the locking plate 4 is locked in the notch 8a of the lower metal fitting B, it is securely fixed in the width direction.

In the figure, 10 and 11 are mounting holes for the mounting pieces 2 and 9 of the upper metal fitting A and the lower metal fitting B, and 12 is a mounting screw.

In addition, FIG. 11 shows a fitting for preventing furniture from falling over, which is equipped with a lifting locking plate 4 according to another embodiment, in which a horizontal bent edge 4c is formed at the lower end of the lifting locking plate 4. .

Next, the effects will be explained.

First, as shown in Fig. 6, attach the upper bracket A with the lifting locking plate 4 to the lower end of the back surface of the upper furniture Fa with the mounting screws 12.
etc., and then fix the lower metal fitting B to the upper end of the back surface of the lower furniture Fb using mounting screws 12 or the like. Then, when the lifting locking plate 4 is pushed down as shown in FIG. When it rides on the slope of the surface slope side 8a and is further lowered, the folded edge 4b falls inside the lower end of the surface slope side 8a of the lower metal fitting B as shown in FIG. Then, the lifting locking plate 4 is slightly pushed up and the folded edge 4b is moved to the inclined surface side 8a of the lower metal fitting B.
It is completed by locking and fixing it to the lower end of the cutout 8a or the edge of the notch 8a (see FIGS. 1 and 9). In this explanation, each state has been described in detail, but in reality, it is possible to push down and lock the push down almost instantaneously. Also, to remove it, perform it in the reverse order from FIG. 9 to FIG. 6.

As described above, in the present invention, the through hole 3 is bored in the U-shaped part 1 of the upper metal fitting A, which has the mounting pieces 2, 2 on both sides of the U-shaped part 1, and the bent edge 4a is formed at the upper end. A vertically elongated hole 5 is bored approximately in the center of the elevating locking plate 4, each of which has a bent edge 4b formed at its lower end, and the elongated hole 5 of the elevating and lowering locking plate 4 is connected to the U-shaped portion 1 of the upper metal fitting A. A rivet 6 is provided between the hole 3 and the rivet 6.
A leaf spring 7 is activated at the rear end so that the elevating and lowering locking plate 4 can be raised and lowered while being in close contact with the upper metal fitting A at all times, and mounting pieces 9 are provided on both sides of the U-shaped portion 8. Surface slope side 8a of U-shaped portion 8 of lower metal fitting B provided
The lifting locking plate 4 is attached to the lower end of the surface inclined side 8a of the U-shaped portion 8 of the lower metal fitting B.
By making it possible for the folded edge 4b of the folding edge 4b to be properly locked, by installing this between the upper furniture Fa and the lower furniture Fb, firstly, the upper furniture Fa is prevented from falling, and secondly, the upper furniture Fa is prevented from falling. It absorbs vibrations and maintains a fixed state, making the entire furniture safe.
Thirdly, the locking operation can be performed very easily and quickly, and fourthly, the elevating and lowering locking plate 4 is always attached to the upper metal fitting A, which has the effect of preventing loss or the like.

To explain in detail the action of absorbing vibrations, first,
Even if the upper furniture Fa vibrates during vibrations such as an earthquake, when the vibration is propagated to the lifting locking plate 4 via the upper metal fitting A, the elasticity of the leaf spring 7 attached to it will provide a buffering effect. The folded edge 4b acts as if to absorb the vibration, and the folded edge 4b is securely engaged with the lower end of the inclined surface side 8a of the lower metal fitting B, and the mutual contact between the upper metal fitting A and the lower metal fitting B is maintained. The fixed state can be firmly maintained, the upper furniture Fa can be prevented from falling over, and the entire furniture can be installed extremely safely.

Further, since the lifting/lowering locking plate 4 can be easily locked or unlocked by lifting/lowering from the outside, it can be easily operated with one touch even on the back side of furniture, which is extremely difficult to reach.

Note that the lower end of the lifting locking plate 4 has a horizontal bent edge 4.
Even if the rivet 6 is formed in the shape of c, substantially the same effect as described above can be achieved in terms of the strength of the rivet 6, etc. Further, a protruding piece 1b is attached to the lower end of the surface side 1a of the U-shaped portion 1 of the upper metal fitting A.
If provided, the projecting piece 1b serves as a guide for the vertically long hole 5 of the elevation locking plate 4, and vertical movement can be made.
