Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fall prevention device support device, a fall prevention device, and a shelf.

[0002]

2. Description of the Related Art Conventionally, for example, a bookcase is formed in the shape of a square box having an opening on the front side, and a plurality of shelves formed in the shape of a plate are provided inside the bookcase so as to extend in the horizontal direction. There is. Then, the books are stored in the bookcase by placing the books on the shelves through the front opening of the bookcase. However, in the bookcase, when a book placed on each shelf slips at the time of an earthquake or the like, the book may fall down from the front opening of the bookcase on each shelf.

Therefore, it is conceivable to provide, as a fall prevention member, a protrusion protruding upward and extending along the edge on the edge of the front side of the bookcase on the upper surface of each shelf. In this case, even if the book on each shelf slides toward the front opening of the bookcase due to an earthquake or the like, the book will be caught in the protrusion of each shelf, so the book will open on the front opening of the bookcase on each shelf. It is possible to prevent falling from below.

[0004]

However, in the above bookcase, when a book is put in or taken out from the front opening, the book easily gets caught in the projection of each shelf, so that the book can be put on and taken off from each shelf. There is a problem in that the protrusion is an obstacle.

The present invention has been made in order to solve the above problems, and a first object thereof is to prevent the fall prevention tool from interfering with the loading and unloading of an object on a shelf.

A second object is to securely hold the mounting portion at the position when the fall prevention tool shields the upper edge of the shelf. A third object is to allow the protrusion of the attachment portion to be easily fitted into the recess of the support portion.

A fourth object of the present invention is to make it possible to easily attach a fall prevention device which does not hinder loading and unloading of an article to a shelf that has already been manufactured.
A fifth object is to allow an object to be easily placed on and off from the placing part of the shelf.

[0008]

In order to achieve the above object, in the invention according to claim 1, a fall prevention tool for shielding the upper side of the edge of the shelf from a direction orthogonal to the extending direction of the edge. Is provided, and the fall prevention tool attached to the attachment section rotatably supports the attachment section so that the upper edge of the shelf is opened or shielded, and the fall prevention tool is attached to the edge of the shelf. Holding means for holding the mounting portion is provided at a position when the upper side of the portion is shielded.

According to a second aspect of the present invention, there is provided a fixing portion to be attached to the shelf, a supporting portion protruding upward is provided to the fixing portion, and a mounting portion to which a fall prevention tool is attached to the supporting portion. Is rotatably supported, and a protrusion is formed on one of the support portion and the attachment portion, and a recess for fitting the protrusion is provided on the other side. The part constituted the holding means.

According to a third aspect of the present invention, the attachment portion is provided so as to be movable in the vertical direction, an arc-shaped guide surface projecting upward is formed on the upper surface of the support portion, and the recess is formed. The protrusion is provided on the support portion and opens upward on the guide surface, and the protrusion is provided on the attachment portion and comes into contact with the guide surface when the attachment portion is rotated.

According to a fourth aspect of the present invention, in particular, a fall prevention tool is provided on the fixed portion attached to the shelf, and the fall prevention tool is rotated with respect to the fixed portion so that the upper edge of the shelf is shielded or opened. A holding means is provided for movably supporting the fall prevention tool at a position when the upper edge of the shelf is shielded.

According to a fifth aspect of the present invention, in particular, the fall prevention tool is rotatably supported so as to shield or open the upper edge of the placement section, and the fall prevention tool is placed on the edge of the placement section. Holding means was provided to hold the side in the position when it was shielded.

That is, according to the first aspect of the invention, the fall prevention tool is attached to the attachment portion of the support device of the fall prevention tool. Then, when the mounting portion to which the fall prevention tool is attached is rotated and the upper edge portion of the shelf is shielded by the fall prevention tool with respect to the direction orthogonal to the extending direction of the same edge portion, the attachment portion is held by the holding means. To be done. Items on the shelf are prevented from falling off the shelf by fall arresters. In addition, when loading or unloading an object on or from a shelf, the fall prevention tool is moved from the upper edge of the shelf by rotating the attachment section with the holding section released by the holding means. The upper side of the edge is opened with respect to the direction orthogonal to the extending direction of the same edge.

According to the second aspect of the invention, in addition to the operation of the first aspect of the invention, the attachment portion is manually held and rotated so that the fall prevention tool is located above the edge of the shelf. Then, when the fall prevention tool is located above the edge of the shelf, the protrusion and the recess are positioned so that the protrusion is fitted into the recess, and the mounting portion is held at that position.

According to the third aspect of the present invention, in addition to the function of the second aspect of the invention, when the attachment portion is rotated so that the fall prevention tool is located above the edge of the shelf, the protrusion of the attachment portion is formed. Contact the guide surface. When the mounting portion is further rotated, the protrusion of the mounting portion moves along the guide surface, and the mounting portion is pushed upward by the guide surface via the protrusion. Then, when the protrusion of the attachment portion is positioned corresponding to the recess of the support portion, the protrusion falls into and is fitted into the recess.

According to the fourth aspect of the present invention, the fall prevention device is attached to the shelf by attaching the fixing portion provided in the fall prevention device to the shelf. Then, the fall prevention tool is rotated to be positioned above the edge of the shelf, and the fall prevention tool shields the upper side of the edge of the shelf with respect to the direction orthogonal to the extending direction of the edge. The fall prevention tool is retained. Items on the shelf are prevented from falling off the shelf by fall arresters. When loading or unloading an object on or from a shelf, the fall-prevention tool is rotated from the upper edge of the shelf by rotating the fall-prevention tool while holding the fall-prevention tool by the holding means. Then, the upper side of the edge is opened with respect to the direction orthogonal to the extending direction of the same edge.

According to the fifth aspect of the invention, the fall prevention tool is rotated so as to be positioned above the edge portion of the mounting portion, and the fall prevention tool causes the edge upper portion of the mounting portion to extend in the direction in which the edge portion extends. When the shield is shielded in a direction orthogonal to the direction, the holding means holds the fall prevention tool. Items on the mounting portion are prevented from falling from the mounting portion by the fall prevention tool. In addition, when an object is to be placed on or off from the placing section, the fall preventing tool is rotated by holding the fall preventing tool by the holding means so that the fall preventing tool is attached to the edge of the placing section. It is moved from the upper side of the part, and the upper side of the edge is opened in the direction orthogonal to the extending direction of the same edge.
