Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to a fall prevention device for articles placed on a shelf, such as a large number of magnetic tapes used in computers, for example.

[Prior art]

Magnetic tape wound on reels used in computers is usually housed in a case of the same shape, and when necessary, the magnetic tape (hereinafter simply referred to as tape) is placed horizontally on a shelf so that it can be easily taken out. Since they are stored in piles, they are likely to fall off due to vibrations on shelves without front doors.

Conventionally, as the simplest means of preventing falls, the lower ends of the legs of the oblong gate-shaped front frame for fall prevention are removably inserted into the mounting holes drilled in the shelf board, just before the tape, and the front frame is fixed. By standing upright, the tape was prevented from falling by its horizontal rod.

However, with this device, it was troublesome to have to attach and detach the front frame every time the tape was inserted or removed, and since the location of the mounting holes for the high shelves was particularly difficult to see, attaching the front frame was troublesome, and there was also the risk that the removed front frame would be lost or be put away in a difficult location.

For this reason, various devices have already been provided in which the front frame can be moved to a position where it does not interfere with tape loading and unloading by a simple operation without removing the front frame.

No. 10198, Jitko No. 56-35078, Jitko No. 57-52783

[Problems that this invention attempts to solve]

However, these devices have drawbacks such as being complex in structure, cumbersome and expensive to manufacture, and lacking in reliability and being at risk of breaking down after long-term use. Ta.

[Means for solving problems]

In the present invention, the structure of the falling part arresting device is such that a large number of vertical holes arranged in a row in the vertical direction are bored in the opposite sides of both the left and right pillars, which are set upright at a predetermined interval. In a shelf with shelves suspended in holes, the base ends of support rods facing at right angles are fixed near both ends of the horizontal rods facing left and right, and the free ends are rotated around the left and right axis in front of the shelves. In addition to being movably pivoted, elastically bendable folded pieces are provided at both ends of the horizontal rod, each having an inwardly U-shape and whose outer end curved portion can be removably engaged with a vertically elongated hole. From the lower end of the folded piece, on the outside of the support rod, a grip piece parallel to the support rod is provided, and when the grip piece is forcibly swung in the direction of the support rod, the end of the horizontal rod The above-mentioned problem is solved by making the folded pieces elastically come into contact with each other so that the outer ends of the folded pieces come out of the longitudinal holes.

[Effect]

In this invention, the curved parts of the folded pieces at both ends of the fall prevention front frame are normally engaged with the vertical holes of the support column, so the front frame does not swing and the horizontal rod is kept at a predetermined height. This can reliably prevent items such as tape from falling.

In addition, if you firmly grasp the grip piece on the front frame, both ends of the horizontal rod and the descending piece will elastically flex, and the outer end will move slightly in the direction of the support rod and detach from the vertical hole, allowing you to move the front frame downward. You can freely put in and take out items by hanging it down.

After loading and unloading the article, the curved portion can be engaged with the vertically elongated hole by performing an operation opposite to that described above, thereby preventing the article from falling.

〔Example〕

The drawing shows a shelf for storing tapes, 1
are pillars installed at the four corners of the shelf, and there are many vertical holes 2 arranged in a row in the vertical direction on the inner side facing left and right.
are bored, and a shelf rear plate 3 is attached to the rear surfaces of both rear left and right columns 1.

L-shaped front shelf brackets 4 are removably engaged with the vertical holes 2 of each column 1 that are at the same height by engaging the downward hooks 5 provided on the outer surface thereof. A shelf board 6 as described below is mounted on the shelf holder 4.

A tape mounting groove 7 is formed in the center of the upper surface of the shelf board 6 and is recessed in an arc shape facing the left-right direction, and a large number of mounting holes 8 in two rows of front and rear rows arranged in the left-right direction are also drilled at both front and rear ends. Near both front ends of the shelf board 6,
A square hole 9 is bored.

As shown in FIGS. 4 and 5, the lower ends of the partition frames 10 bent in a chevron shape are inserted into and supported by the mounting holes 8 which face each other in the front and back, and both adjacent partition frames 10
A tape 11 is stored in between.

Reference numeral 12 denotes a front frame made of a metal wire rod to prevent the tape 11 from falling, and near both ends of a horizontal rod 13 facing in the left-right direction, the base ends of support rods 14 facing in a right angle direction are fixed. As shown in FIG. 3, a pivot 15 bent outward at the free end of each support rod 14 is
It is rotatably supported around a left-right axis in a horizontal pivot groove 17 at the center of the mounting plate 16, which passes through the square hole 9 from the inside.

At both ends of the horizontal rod 13, an inward U-shaped folded piece 18 is provided below the horizontal rod 13 when the front frame 12 is swung upward.
Grip pieces 19 that hang down parallel to the handle are successively arranged.

Normally, the outer end of the curved part of the folded piece 18 fits into and engages with the vertically elongated hole 2 above the shelf board 6, so that the front frame 12 stands up just in front of the shelf board 6 and is fixed. Twelve horizontal rods 13 reliably prevent the tape 11 from falling off the shelf board 6.

When loading and unloading the tape 11, use the support rod 14.
At the same time, firmly grasp the grip piece 19.

Then, as shown in FIG. 6a, the folded piece 1
8 and the ends of the horizontal rod 13 are elastically bent, and the outer end of the folded piece 18 is slightly drawn toward the support rod 14 and detached from the vertical hole 2. As shown in FIG. 6b, the front frame By swinging the tape 12 downward, the tape 11 can be freely taken in and taken out.

After the tape 11 has been taken in and out, the curved portion of the folded piece 18 can be engaged with the vertically elongated hole 2 by performing an operation opposite to that described above, thereby preventing the tape 11 from falling.

If the shelf board does not have a rear plate 3 and has openings on both front and rear sides, the above-mentioned device can also be provided on the rear face of the shelf, and the tape 11 can be taken in and out from both sides.

Although the above description has been made regarding the case where the present device is used as a tape mounting shelf, it can also be effectively used, for example, in a display shelf on which articles such as bottles are mounted.

[Effects of this invention]

As mentioned above, the structure and handling of the present invention are as follows.
Both are extremely simple and can be manufactured at low cost, and there is no fear of failure.
