Description

[Detailed description of the invention] Industrial applications The present invention relates to a fall prevention device for storage furniture.

The storage furniture shall broadly include various chests of drawers, bookshelves, cupboards, lockers, etc.

Conventional technology and its problems Many methods for installing storage furniture to prevent it from falling have been proposed and implemented in the past, but all of the practical methods involve tying the storage furniture to the walls or pillars of the house. there were. Therefore, there is a problem in that if an appropriate anti-falling member cannot be fixed to the wall or pillar, no fall prevention means can be taken, and if the wall or pillar is weak, a reliable fall prevention effect cannot be obtained.

The present invention solves the problems of the prior art and can reliably prevent falls even in cases where straightening members cannot be fixed to walls or columns or in houses where walls and columns are weak. The purpose is to provide equipment.

Means for Solving the Problems The object of the present invention is to provide an architrave fixed to the main body of the storage unit;
A rod rotatably mounted in the architrave around an axis, a rotating part for rotating the rod around the rod axis from outside the architrave, and a proximal end fixed to the rod. It extends in a curved manner toward the tip in a plane substantially perpendicular to the axis of the rod, and has a sharp needle-like tip, and as the rod rotates, the tip penetrates and engages the architrave installation surface. This is achieved by a device for preventing overturning of storage furniture, which is characterized by having an engaging claw configured as shown in FIG.

Example Embodiments of the present invention will be described below with reference to the accompanying drawings.

The fall prevention device shown in Figure 1 consists of an architrave (1) and a rod (2).
, a rotating part (3) and an engaging claw (4). architrave(
1) is fixed to the main body of the storage section of the storage furniture. The fixing can be done by an appropriate method such as adhesion or screwing. Alternatively, the architrave (1) may be manufactured integrally with the main body of the storage section from the beginning. Two rods (2) are provided with both ends supported by the front and rear members of the architrave (1). The rod support portion (10) in the architrave (1) is an upwardly convex arc-shaped groove as shown in FIGS. 1 and 3. Both ends of the rod (2) are rotatable and slidable within the support (10), and the bale is supported by a stop. In the rotating part (3), a hexagonal wrench receiver provided on the front end surface of the rod (2) is formed as a hole for inserting it (see FIG. 2).

The engaging claw (4) has its base end fixed to the rod (2) by welding or the like, and its distal end curved in a plane perpendicular to the @ line of the rod (2) and has a sharp needle-like tip. has been done.

In this example, the curvature is a circular arc centered on the lower end of the architrave (1), and the groove-shaped rod support portion (10) corresponds to the curve.
) is formed concentrically with the arc. As a result, the engaging claw (4) slides and rotates within the support part (10) of the rod (2), and as shown in FIGS. The insertion surface (A) can be smoothly inserted into the installation surface (A) as shown in the figure before, during, and after insertion into the installation surface (A).

Of course, if the installation surface (A) is made of a relatively flexible material such as tatami mats, the material will deform when the nail is inserted, so the engagement claw (4) and rod support part (10) may be damaged. The curvature does not necessarily have to be arcuate like this.

When installing storage furniture on, for example, a tatami mat using this fall prevention device, first, the architrave (1) is fixed to the storage unit body and placed at the installation location. Next, attach the rod (2) as shown in Figure 3 (
Place the rod (2) in the position shown in a) using a hex wrench.
It is sufficient to slide the support part (10) through the state shown in FIG. 3(b) to the state shown in FIG. 3(C) while rotating clockwise in the figure. This allows the engaging claw (4) to move onto the installation surface (
△) and engage it in the curved part.
The architrave (1) is prevented from separating from the installation surface, and as a result, the storage furniture and the tatami mat are integrated with each other, and due to the wide installation surface of the tatami, the storage furniture falls over in the event of an earthquake, etc. is prevented.

FIG. 4 shows another example of the engaging pawl and the support part. In this example, the tip of the engagement claw (4a) is curved in a substantially arc shape, and the rod support portion (10a> is a horizontal linear groove.In this example, the installation surface of the claw (4a) (A> is forced into the installation surface (A>) as shown by the dashed line in Figure 4, with deformation of the installation surface (△) and the claw (4a). However, after insertion, the nail retention force is even stronger.

FIG. 5 shows still another example of the engaging claw. Rod support part (
10b) is a circular hole that rotatably supports the rod (2), and the engaging claw (4b) connects the rod (2) with an arcuate portion centered on the support portion (10b). It is formed into a sickle shape and has a linear portion connected to the . When installing storage furniture, from the state where the tip of the claw (4b) faces the installation surface (dotted chain line in Figure 5), the arc-shaped part of the claw (4a) moves toward the installation surface as the rod (2) rotates. (A>), and the engagement of the curved portion provides an integral connection between the installation surface and the storage furniture, thereby preventing the storage furniture from falling over.

In any of the above examples, the positions and numbers of the rods and engaging claws can be determined as appropriate by taking into account the size and weight of the storage furniture, the direction in which it is likely to fall, the operability of the rotating part, etc. In addition to the aforementioned hexagonal wrench receiver hole, the rotating section can be of various types, such as one with a hexagonal nut section, one with a rotary lever and a gear transmission mechanism, etc.

The storage furniture installation surface suitable for the present invention should be such that the insertion of the engagement needle is easy, the holding force after insertion is sufficiently strong, and the installation surface itself is wide and has sufficient rigidity. required to be present. A typical material that satisfies this requirement is tatami mats, but it can of course also be applied to materials made of other materials that meet this requirement, such as foamed synthetic resin.

Effects of the Invention As is clear from the above explanation, according to the present invention, the architrave is integrally connected to the installation surface by the curved engagement claw inserted into the installation surface. By fixing the device to the main body of the storage section, it is possible to provide a fall prevention device for storage furniture that is effective in preventing storage furniture from falling during an earthquake or the like. Therefore, according to the device of the present invention, there is no need to connect the storage furniture to the walls or pillars of the house, and in cases where straightening members are not fixed to the walls or shrines, or where the walls and pillars are weak in the house. It is also possible to reliably prevent storage furniture from falling over.

Furthermore, the device of the present invention is easy to operate, as all you have to do is rotate the rod from the outside of the architrave using the rotating part after installing the storage furniture, and there is no need to process the installation surface in advance, so the installation position can be arbitrary. Therefore, even if the installation location is changed, the traces of the engaging claws will not be a problem.
