Description

[Detailed Description of the Invention] (Industrial Field of Application) This invention relates to an article shelf equipped with a fall prevention bar, and more particularly to an article shelf having a feature in the attachment structure of the fall prevention bar.

(Prior art) A type of article storage shelf has a main body case fitted into an opening formed in an attached part and fixed therein, and a fall prevention bar is provided on the upper part of the shelf provided in the main body case. There are types that are designed to prevent items from falling. FIG. 6 shows an example. This article shelf has a shelf 102 integrally formed with a main body case 100, and on the upper side of the shelf 102, a fall prevention bar 104 made of a bar bent into a U-shape is attached to a bolt/nut. It is fastened by.

(Problem to be solved by the invention) By the way, this article shelf has a fall prevention bar 10.
4 is fixed to the main body case 100 from both the front and back sides with bolts and nuts. Therefore, when attaching the article shelf to a wall surface etc., it is necessary to fix the fall prevention bar 104 to the main body case 100 in advance. In addition, if the fall prevention bar 104 becomes bent or damaged after installing the article shelf and needs to be replaced, the entire main case 100 should be removed from the wall etc. At the top, the fall prevention bar 104 must be removed from the main body case 100, which poses a problem in that it requires a great deal of effort.

In addition, in order to prevent the fall prevention bar 104 from rotating, this article shelf has two holes in each fixed end of the fall prevention bar 104 and in the main body case 100, and these two holes are The bolts and nuts must be tightened at each fixed end, and even if this is done, it is not possible to widen the distance between the holes at each fixed end (because the depth of the main body case 100 is limited). Prevention bar 104
The fixing force of the bar 104 was weak, and the fall prevention bar 104 was prone to wobbling.

(Means for solving the problem) The present invention was made to solve the above problem, and its gist is that the main body case is provided with a hole for attaching the fall prevention bar from the front. While the fall prevention bar is provided through the back side, the fall prevention bar is formed by bending both ends of a U-shaped bar upward, and the fall prevention bar is extended until the entire bent portion reaches the back side of the main body case. is inserted into the mounting hole, and with the bent portions in contact with the back surface of the main body case, insert an engagement groove on the outer periphery that is fitted onto the drop prevention bar in advance and engages with the peripheral edge of the mounting hole. The fall prevention bar is fixed to the main body case by fitting the formed ring-shaped gasket into the mounting hole.

(Function) As described above, the article shelf of the present invention can be fixed by inserting the fall prevention bar into the mounting hole of the main body case and fitting the gasket into the hole. No work required behind the case. Therefore, after the main body case is fixed to a wall surface or the like to be attached, the fall prevention bar can be fixed to the case, and the fixing work at that time can be easily performed.

In addition, the fall prevention bar can be removed by simply removing the seal from the mounting hole and pulling out the fall prevention bar from the mounting hole, making it easy to replace the fall prevention bar without having to take the trouble of removing the main body case from the part to which it is attached. It can be carried out.

In addition, in this product shelf, the bent part of the fall prevention bar that rises from the back of the main case comes into contact with the back of the main case to prevent rotation.
The fall prevention bar is securely fixed to the main case without wobbling.

In addition, the article shelf of the present invention is configured so that the gap between the mounting hole of the main body case and the fall prevention bar is filled with a ring-shaped packing.
This mounting hole can be made relatively large,
This facilitates the insertion operation of the fall prevention bar. Moreover, since the mounting hole is well sealed by attaching the seal, there is no need to worry about water leaking from the same area.

(Example) Next, an example of the present invention will be described in detail based on the drawings.

In FIGS. 2 and 3, reference numeral 10 denotes an article storage shelf which is an embodiment of the present invention, and includes a main body case 14 provided with a recess 12 and a plurality of shelves 16 integrally formed in the main body case 14. have. Further, a fall prevention bar 18 is attached to the upper portion of each shelf 16 via a packing 30 in a through hole (attachment hole) 20 (see FIGS. 4 and 5) provided in the main body case 14.

As shown in detail in FIG. 1, the fall prevention bar 18 is formed by vertically bending both ends of a U-shaped bar, and as shown in FIG.
The upper portion of the bent portion 26 serves as a contact portion 28 that is brought into contact with the back surface of the main body case 14.

On the other hand, as shown in detail in FIGS. 4 and 5, the packing 30 includes a large-diameter proximal end 32, an elastic part 34 whose wall thickness becomes thinner toward the outer circumference, and an annular ring formed between them. It has a ring shape with a groove (engaging groove) 36, and the hole in the center fits into the main body part 24 of the fall prevention bar 18, and the annular groove 36 fits in the peripheral part of the mounting hole 20. It is attached to the main body case 14 in a fitted state.

The fall prevention bar 18 of this example can be attached to and detached from the main body case 14 very easily. To explain the specific procedure, first, as shown in FIG. 1, a pair of gaskets 30 are fitted into the main body part 24 from both ends of the fall prevention bar 18, and then, as shown in FIG. Insert the folded portions 26 at both ends into the mounting holes 20 of the main case 14 until the entire bent portions 26 reach the back side of the main case 14. When the entire bent portion 26 reaches the back side of the case 14, return the fall prevention bar 18 to the horizontal position, and then slide the gasket 30 that has been fitted in the main body portion 24 in advance toward the tip side and fit it into the mounting hole 20.
The annular groove 36 on the outer periphery is fitted into the peripheral edge of the mounting hole 20. Then, the contact part 28 of the bent part 26 of the fall prevention bar 18 comes into contact with the back surface of the main body case 14, while the packing 30 contacts the fall prevention bar 18 and the mounting hole 2.
0 is filled under a certain elastic force (the diameter of the packing 30 is selected in advance), and the fall prevention bar 18 is moved to the main body case 14.
It is firmly fixed. That is, even when a load is applied from above to the fall prevention bar 18,
The fall prevention bar 18 does not wobble due to the supporting action of the contact portion 28, and the gasket 30 is filled in the gap between the fall prevention bar 18 and the mounting hole 20.
The fall prevention bar 18 will not rattle.

Incidentally, in order to remove the fall prevention bar 18 from the main body case 14, the above-mentioned operation may be reversed. That is, the gasket 30 may be removed from the mounting hole 20, then the fall prevention bar 18 may be tilted diagonally, and the bent portion 26 may be removed from the mounting hole 20.

In this way, in the article shelf 10 of this example,
The fall prevention bar 18 can be attached and detached from the main body case 14 very easily, and there is no need to attach the fall prevention bar 18 to the main body case 14 in advance, and there is no need to temporarily remove the main body case 14 from the part to which it is attached, such as a wall surface. . Therefore, even when replacing the fall prevention bar 18, the work can be done extremely easily.

Although the embodiments of the present invention have been described in detail above, the present invention can also be configured in other forms.

For example, if the elastic part 34 at the tip of the packing 30 is formed into a circular shape, it is desirable to improve the sealing performance of the mounting hole, but such an elastic part does not necessarily have to be circular; It is also possible to provide them intermittently at regular intervals.

In addition, the present invention can also be applied to an article shelf in which the main case and the shelf are provided separately, etc.
It is possible to make various modifications and configurations based on the knowledge of those skilled in the art without departing from the spirit of the invention.

(Effects of the Invention) As described above, in the present invention, the tip of the fall prevention bar is bent and the fall prevention bar is attached to the main body case by the action of the bent part and the packing.

This makes it easier to attach and detach the fall prevention bar, eliminates the need to remove the main body case from the part to which it is attached when replacing it, and also eliminates wobbling of the fall prevention bar and improves sealing performance, among other excellent effects. occurs.
