Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to a device for preventing objects from falling on storage shelves.

BACKGROUND TECHNOLOGY In order to prevent items placed on storage shelves from rolling off the shelves or falling down in the event of an earthquake, etc.
There are storage shelves that have members installed at the frontage of the shelves to prevent objects from falling. The one described in Japanese Utility Model Application Publication No. 56-30051 is an example of this.

Problems to be Solved by the Invention The present invention further improves the conventional device for preventing objects placed on storage shelves from falling, and has a simple structure, good operability, and a device that prevents objects from falling when earthquakes or other vibrations occur. It is an object of the present invention to provide a device for preventing objects from falling on a storage shelf that reliably maintains an object falling prevention position.

Means for Solving the Problems In order to solve the above problems, the present invention has both ends bent to form a gate shape, and can be rotated while maintaining a position parallel to the frontage surface of the shelf. A fall prevention member whose both ends are pivotally supported on the side of the article placement section, and when this fall prevention member is in a standing position located above the object placed on the shelf board, and a passage for taking in and out of the above-mentioned object. A locking portion is provided for locking the fall prevention member in each of these positions when the fall prevention member is in the upwardly protruding position.

Effect According to the present invention, if the fall prevention member is rotated so that it is in a standing position above the object placed on the shelf board, the fall prevention member is placed in this position. Because it is locked by the locking part,
Placed items can be taken in and out without any hindrance. In addition, if the fall prevention member is rotated until it assumes a lying position in which the above-mentioned ornament is put in and taken out, the fall prevention member is locked by the locking part in this lying position, so that the fall prevention member can be prevented from falling. The member prevents objects placed on the shelf from falling. Furthermore, if the shelf vibrates due to an earthquake or other cause while the fall prevention member is in the standing position above the objects placed on the shelf, the fall prevention member will rotate under its own weight and fall down. to prevent the placed items from falling.

Embodiments The present invention will now be described with reference to illustrated embodiments.

In the figure, reference numeral 7 indicates a shelf support, 12 indicates a shelf board support member, and 13 indicates a fall prevention member 14 for a shelf board. In the illustrated example, the support columns 7 form a double-post type shelf arranged in pairs at the front and rear of the shelf, but only the front support column is shown. However, whether it is a double-post type or a single-post type is irrelevant to the gist of the present invention. At both front and rear ends of the shelf support member 12, hook-shaped hook portions 12a are bent laterally and protruded. This latching portion 12a is connected to the front and rear supports 7 of the shelf.
It is hung in one of the holes 7a arranged vertically on the side surface of the screen. The lower edge of the shelf support member 12 is bent horizontally to form a bent lower edge 12b, and the vertical surface of the shelf support member 12 has an L.
A letter-shaped embossed portion 12c is formed. One end of the shelf board 14 is placed on the bent lower edge 12b, and the shelf board 14 is placed on the punched out part 12c.
The shelf board 14 is immovably supported by being hooked to a notch (not shown) on the side surface of the shelf board 14. It is assumed that the other end of the shelf board 14 is also supported by a similar structure. The shelf board 14 is divided into front and rear halves and is supported by being arranged in front and back, and a disc-shaped object 15 such as a magnetic tape can be placed upright across the front and rear shelf boards. The upper surface of the rear half of the front shelf board 14 and the upper surface of the front half of the rear shelf board (not shown) are formed to form slopes, and a groove is formed between both the front and rear shelf boards to receive the lower part of the object 15. It is becoming more and more common. However, the shape of the shelf board can be made arbitrarily according to the shape of the placed object, etc., and may be a single shelf board in the form of a flat plate. The sides of the article placement section, specifically, the central part of the shelf support member 12 in the front and back direction, have both ends bent at right angles to form a gate shape, and both ends bent outward at right angles. The bent portions 13a at both ends of the fall prevention member 13 for the placed object
is inserted. As a result, the fall prevention member 13
can be rotated in the vertical direction while maintaining a position parallel to the frontage surface of the shelf board 14. Although the fall prevention member 13 is formed of a round bar in the illustrated example, it is not necessarily limited to a round bar. As shown by the solid line in the figure, when the fall prevention member 13 is rotated to a position where it stands up approximately vertically and is located above the object 15 on the shelf board 14, it engages with the appropriate locking portion. It is locked and held in the above position, and further rotation is prevented. In addition, the fall prevention member 13 is indicated by a chain line 13A in the figure.
When it is rotated forward and laid down as shown in , it is locked in the laid down position by the locking portion 16 fixed to the shelf support member 12, and it cannot be moved further in the laying down direction. It is designed to prevent it from rotating. A thinking spring may be applied to the falling prevention member 13 so that the falling preventing member 13 maintains a vertically standing position at a position slightly beyond the thinking point of the thinking spring. Fall prevention member 1
3, when in the standing position as mentioned above, stepping over the placing object 15 will not hinder the work of putting in and taking out the placing object 15, and also in the lying down position as mentioned above. At certain times, it advances onto the loading/unloading path of the loaded object to prevent the loaded object 15 from falling. The locking portion that locks the fall prevention member 13 in the standing position locks the fall prevention member 13 in the substantially vertical position, and the fall prevention member 13 is directed toward the collapsed position due to the vibration of the shelf. It was once placed in a position where it could be rotated.

Therefore, when the object 15 is to be put in or taken out from the shelf board 14, the fall prevention member 13 is rotated until it assumes a standing position. Further, when the loading/unloading operation of the placed object is completed, the fall prevention member 13 is rotated forward and placed in a prone position to prevent the placed object 15 from falling. Even if you forget to turn the fall prevention member 13 to the collapsed position after loading and unloading the items 15, it is possible that the shelf will receive enough vibration to cause the items 15 to fall due to an earthquake or other cause. Then, the fall prevention member 13 rotates under its own weight due to vibration and assumes a lying position, thereby preventing the placed object 15 from falling.

Note that the support of the fall prevention member may be a support depending on the structure of the shelf, or may be a shelf board. The storage shelf provided with the device of the present invention may be a movable shelf or a fixed shelf.

Effects of the invention According to the invention, it is only necessary to rotatably support the fall prevention member formed in the form of a gate, and to provide a locking portion that locks the fall prevention member in the standing position and the collapsed position. The structure is simpler than that of conventional devices for preventing objects from falling, and the fall prevention member can be operated by simply rotating it. There is no need for troublesome operations such as hooking the device onto the device, and an easy-to-operate device for preventing the placed object from falling can be provided. Furthermore, even if you forget to set the fall prevention member to the collapsed position, when the shelf vibrates due to an earthquake or other cause, the fall prevention member, which is in the raised position, will rotate under its own weight and automatically return to the collapsed position. This also has the effect of preventing the placed object from falling.
