DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for converting a component of a load applied to a corner shelf into a force for pressing a wall, which is attached to a corner where two walls intersect.

[0002]

2. Description of the Related Art In a conventional corner shelf, an adhesive is used on a wall surface, a support bracket is fixed with screws, and a shelf plate is placed thereon, or a suction cup or a magnet is held. It was known that it was attached to the wall only by force and held.

[0003]

In the corner shelf described in the prior art, the method of mounting using an adhesive is such that the adhesive may deteriorate over time and fall, and the supporting bracket may be screwed. The method of mounting the shelf board by fixing the tool is troublesome because a tool is used for mounting, and the above two methods cannot easily change the mounting height if necessary. In addition, a method of holding a corner shelf using a magnet or a suction cup, which can be mounted at a variable height, is widely known, but has a problem that only relatively light articles can be placed. .

The present invention has been made in view of the above-mentioned problems of the prior art, and has as its object to not only hold a corner shelf with an adhesive or a magnet or a suction cup, but also perform a wedge action. Therefore, it is intended to provide a corner shelf having a device that increases the pressing force against the wall surface in proportion to the load, since the component force of the load applied to the corner shelf is converted into the pressing force on the wall surface. Things.

[0005]

Means for Solving the Problems In order to achieve the above object, means for converting a load component applied to a corner shelf into a wall pressing force according to the present invention will be described below. Opposite to each of the two intersecting wall surfaces, a downwardly inclined slope is formed, and both support members held on each of the two wall surfaces have the same position corresponding to the slope of the load receiving member. An apparatus for converting a component force of a load into a wall pressing force, wherein an inclined surface having an angle is formed upward, and the inclined surface of a load receiving member is mounted on the inclined surface.

The load receiving member is formed with an arc portion facing each of the two intersecting wall surfaces, and the support members held on each of the two wall surfaces are also provided with an arc portion of the load receiving member. A device for converting a component force of a load into a wall pressing force in which an inclined surface having an upward angle is formed at a position corresponding to the inclined surface, and an arc portion of a load receiving member is placed in contact with the inclined surface. .

In the load receiving member, a downwardly inclined slope is formed opposite each of the two intersecting wall surfaces, and the load is also applied to both the support members held on each of the two wall surfaces. An apparatus for forming a supporting arc portion at a position corresponding to a slope of a receiving member, and placing the supporting arc portion with the slope of the load receiving member in contact with the supporting arc portion.

In the load receiving member, corners are formed opposite to each of the two intersecting wall surfaces, and both support members held on both wall surfaces correspond to the corners of the load receiving member. A device that converts a component force of a load into a wall pressing force by forming an inclined surface having an upward angle at a position where the load is applied, and placing the inclined surface of the load receiving member in contact with the corner.

The load receiving member has a downwardly inclined surface facing each of the two intersecting wall surfaces, and the load is also applied to both support members held on each of the two wall surfaces. A device for forming a support corner at a position corresponding to a slope of a receiving member, and placing the support with the slope of the load receiving member in contact with the support corner to convert a component force of the load into a wall pressing force.

[0010]

The operation will be described based on the configuration of the corner shelf according to the present invention. The load applied to the load receiving member is a downward force acting by gravity, and the downward force is divided into a vertical component and a horizontal component by a wedge effect. Since it can be decomposed into a force, the horizontal component becomes a force pressing the wall surface. The smaller the angle between the inclined surface of the load receiving member and the inclined surface of the supporting member, the greater the horizontal component of the downward force due to the load is converted to the force of pressing the wall surface.

According to another aspect of the present invention, an inclined surface is formed on a load receiving member, or an inclined surface is formed on both support members held on a wall surface. In the position, the circular arc part, the supporting circular arc part, the corner part, or the supporting corner part is formed and the load receiving member is placed on the supporting member, so that the load applied to the load receiving member is directed downward by gravity. If the force has either the inclined surface of the load receiving member or the inclined surfaces of both support members, the horizontal component force of the downward force due to the load is converted into the force pressing the wall surface by the wedge action.

The same applies to the case where a plurality of the load receiving members 61 are provided.

Further, in the embodiment of the present invention, the contact portion between the load receiving member and the support member is a mechanism for placing the load receiving member on the support member by any of surface contact, line contact, and point contact. However, the contact area is effective because the line contact is smaller than the surface contact and the point contact is smaller than the line contact, so that the friction is small and the loss of the force pressing the wall surface is small.

[0025]

Since the present invention is configured as described above, it has the following effects. At the corner of the two intersecting walls, it can be installed at the desired height, and with a simple mechanism, the component force of the load can be converted to the wall pressing force, so if the load is heavy, the wall will be proportionately The pressing force is also large, especially when compared to conventional corner shelves that are held only by suction cups or magnets. Since the shelf can be hung from the load receiving member, it is possible to increase the loading area of the articles.
