Description

[Detailed description of the invention] (Field of industrial application) The present invention relates to a metal fitting that prevents furniture, bookshelves, rockers, etc. from falling over or moving during an earthquake.

(Prior Art) In the event of a major earthquake, furniture, bookshelves, lockers, etc. often fall over or move significantly, causing damage.

Such movement and overturning of furniture occurs when the force acting on the furniture due to an earthquake is greater than the frictional force acting on the surface of the furniture in contact with the floor, or when the resultant vector of the seismic force and the furniture's own gravity This occurs when the direction of is directed toward the outside of the bottom plate of the furniture.

Conventionally, in order to prevent such overturning and movement, furniture has been fixed to strong locations such as walls and floors using metal fittings.

(Problems to be solved by the invention) However, the above-mentioned conventional means for preventing furniture from falling or moving damages the building structure, and requires modification when changing the installation location of furniture, which is time-consuming. There was a problem.

(Means for solving the problem) The present invention was proposed in order to solve the above problem, and it includes anti-slip materials with a large friction coefficient on the lower floor contact surface and the upper furniture support surface, respectively. A vertical member for supporting the lower front end of the furniture is protruded on the layered horizontal bottom plate, and the width of the horizontal bottom plate is set so that the direction of the composite vector of the furniture's own gravity and horizontal seismic force is the same as that of the horizontal bottom plate. This relates to a metal fitting for preventing furniture from falling or moving, which is characterized by being designed to fit within the width of the furniture.

(Function) As described above, the fitting for preventing furniture from falling or moving according to the present invention has a vertical member protruding from the horizontal bottom plate that supports the front lower end of the furniture, and the upper surface that supports the furniture. and anti-slip materials with a high coefficient of friction are layered on the lower surface of the building structure in contact with the floor surface of the building structure where the furniture is installed, so a large frictional force is generated between the metal fittings and the floor and furniture. This will prevent the furniture from moving during an earthquake.

Furthermore, the width of the horizontal bottom plate of the metal fittings is configured such that the direction of the composite vector of the furniture's own gravity and horizontal seismic force falls within the width of the horizontal bottom plate, thereby preventing the furniture from falling during an earthquake. be done.

(Effect of the invention) According to the fall and movement prevention fitting according to the present invention, with such a simple structure, it is possible to prevent furniture from falling and moving during an earthquake. It will not damage the class.

Therefore, the present invention is suitable for walls made of materials that are difficult to fix.
It can be applied to floors and furniture, as well as apartment complexes where it is preferable not to fix metal fittings, stores where furniture is frequently moved, and furniture as a product.
This applies to bookshelves, lockers, etc.

(Example) The present invention will be described below with reference to the illustrated embodiments.

In Figure 1, 1 is a horizontal bottom plate, and considering both the bottom plate B of the furniture A placed on it and the material of the floor C, the frictional force and anti-slip materials 2 and 3 that increase are A vertical member 4 is integrally layered on the upper and lower surfaces of the bottom plate 1 and protrudes from the bottom plate 1 for supporting the lower front end of the furniture A.

Furthermore, in FIG. 2, the width b of the bottom plate 1 is the resultant vector T of the own gravity W of the furniture A and the horizontal seismic force H.
The direction is designed to fall within the width b of the bottom plate 1.

In the figure, D is the wall, and G is the center of gravity of the furniture A.

Since the illustrated embodiment is constructed as described above, the horizontal bottom plate 1 is placed on the floor C, the furniture A is placed on the bottom plate 1, and the furniture A is placed in front using the vertical members 4. The furniture A is set in a room by supporting the lower end, and the space between the furniture A and the anti-slip material 2 on the top surface of the horizontal bottom plate 1, and between the bottom surface of the horizontal bottom plate 1 and the non-slip material 3 in the event of an earthquake. The fact that the frictional force acting between the In addition, the horizontal seismic force H and the self-gravity W of furniture A
Since the direction of the resultant vector T falls within the width b of the horizontal bottom plate 1, the furniture A is prevented from falling over.

Note that when the floor C is inclined, the thickness of the horizontal bottom plate 1 can be adjusted to keep the furniture A horizontal and vertical.

As described above, according to the illustrated embodiment, furniture A can be set up without damaging not only walls D and floors C but also furniture A, and movement and overturning of the furniture A can be prevented.

FIG. 3 shows another embodiment of the present invention, in which a pair of vertical members 4a, 4a are provided protruding from the horizontal bottom plate 1 in an inverted 〓 shape, and FIG. 4 shows an inverted 〓 shaped metal fitting shown in FIG. In the embodiment shown in FIG. 5, a cylindrical vertical member 4b is provided protruding from the horizontal bottom plate 1, and in the embodiment shown in FIG. 6, the metal fittings shown in FIG. 5 are separated. It is.

According to the embodiments shown in FIGS. 3 to 6, by supporting the supporting legs A' of furniture, bookshelves, rockers, mirrors, vases, pianos, etc., it is possible to prevent them from moving or falling. It is something.

In addition, in FIGS. 3 to 6, the anti-slip materials 2 and 3 layered on the upper and lower surfaces of the horizontal bottom plate 1 are omitted.
