[0010] The fall prevention mechanism of the present invention is provided on the shelf described above.
Since the present invention is applied to the case where the exclusive tray 5 for a cartridge is formed, the exclusive tray 5 and the fall prevention mechanism will be described below.

First, the dedicated tray 5 installed on the upper surface of each shelf 4 has the structure shown in FIG. 1 as an example.
This tray 5 has left and right plates 5 at the left and right ends when viewed from the front.
a, 5b, and a plurality of partitioning plates (not shown in the figure) between them, and a vertical wall 5 serving as a front and rear stopper
c, 5d, and a bottom plate 5e having a substantially stepped cross section
Between the left and right plates 5a, 5b, the front and rear walls 5c,
It is arranged and configured between 5d. Here, the front and rear standing wall portions 5c and 5d are formed so that the front side (entrance side) is lower and the side facing (rear side) is higher. In addition, the stepped bottom plate 5e
Has a protruding portion 5f formed at a position approximately one-third in the depth direction. There is also a dedicated tray without the above-mentioned partition plate.

In the embodiment of FIG. 1, the dedicated tray 5 is
A single shelf is provided in two rows in the same direction, overlapping the front and rear, and a plurality of pieces are arranged in the length direction. For this reason, the plurality of trays 5 located on the article entry / exit side of the shelf 4, that is, on the near side, are slidable in the longitudinal direction of the shelf 4, so that at least one tray 5 is located in the rear row. Placed less than columns.

However, the entry and exit of the articles on the shelf 4 is
If the tray 5 is formed from both front and rear sides, the row of the trays 5 on the rear row is provided back-to-back with the row of the trays on the front side. There is no need to reduce and slide.

If the shelf 4 is of a so-called single width in which only a single row of trays 5 can be installed in the front-rear direction of the shelf, the tray 5 is installed in only one row toward the article entry / exit side. You don't need to slide it. In the shelf board 4 of FIG. 1, reference numerals 4a and 4b denote locking projections for a dedicated tray 5 formed upright along the front and rear sides of the shelf board 4.

In the above description, an example is shown in which the exclusive tray 5 is mounted on the shelf plate 4 and formed.
5 can also be formed integrally with the shelf 4 and it can be arbitrarily selected whether it is separate or integrated. The shape and structure of the dedicated tray 5 are not limited to those shown in FIG. For example, the tray shown in FIG. 6 or a tray having another cross-sectional shape may be used.

Cartridges C of the same shape shown by broken lines in FIG. 1 are placed side by side on the dedicated tray 5 arranged on the upper surface of each shelf plate 4 as described above. This cartridge C
A magnetic tape or the like on which various data are recorded is stored inside, and many of them are arranged and stored in the above-mentioned dedicated tray 5, and the bottom plate 5e of the tray 5 is provided. Due to the stepped cross-sectional shape, the cartridges C are supported by the tray 5 at three points P ₁ , P ₂ , and P ₃ of the front surface C ₃ and the bottom surface C ₄ thereof, and are lined up with the front side raised. . The exclusive tray 5 of the present invention may be a tray for articles that can be arranged in an upright position such as a video cassette, an audio cassette, a CD cassette, and a book, in addition to the cartridge C. Good.

[0017] Then, all mosquitoes - cartridge C is the same size all, moreover, since the line up at the same position, to take out the one among them that force - pressing the front side of the upper surface C ₁ of the cartridge C with fingers Then, the cartridge C is rotated to the near side with the vertex of the convex portion 5f as a fulcrum to take out the cartridge C from a row of other cartridges C so that the cartridge C can be picked or grasped. ing.

In order to take such a mode of taking out, even if the fall prevention means is provided, the taking-out operation becomes troublesome if the movable fence-shaped object is simply provided on the taking-out side. Accordingly, the present invention is directed to a cartridge C stored therein.
Contact to the upper surface C ₁ of a mechanism for pressing the upper surface, if,
Even if the shelf plate 4 shakes or vibrates, it does not fly out or fall. Next, an embodiment of the falling portion prevention mechanism will be described.

In FIGS. 1 and 2, reference numeral 6a denotes a mechanism mounting pedestal provided on the lower surface of the shelf 4 immediately above the shelf 4 on which the dedicated tray 5 is provided. 4
It is formed by attaching it to the back surface via a horizontal member 6b.

Reference numeral 7 denotes a fall prevention member which is mounted on the pedestal 6a via a spring hinge 8 so as to be capable of angular rotation in the front-rear direction of the shelf 4 (here, toward the back of the shelf 4).
As shown in FIG. 7, the upper plate 7a is composed of a thin rectangular cylindrical base 7b in which the upper plate 7a is fitted, and a spring 7c is provided inside the base 7b to urge the upper plate 7a upward. Together with the substrate
A guide groove 7d or a long hole is provided on both side walls of 7b, and protrusions 7e provided at lower ends on both sides of the upper plate 7a are loosely fitted in the guide groove 7d, so that the upper plate 7a is vertically movable within the base 7b, It is elastic as a whole.

When the fall prevention member 7 shown in FIG. 3 is in the hanging posture, the lower edge of the base 7b is positioned on the upper surface of the cartridge C.
Looking to C ₁ a plate-like member abutting against the height from the front of the shelf, side by side housed a mosquito - cartridge C Shelf 4 column and the top of the
Are provided in a manner like a curtain plate for closing a space formed between the back surfaces of the shutters.

However, the fall prevention member 7 is always held in a hanging position by the action of the spring of the spring hinge 8 here.
The hinge 8 rotates about 90 degrees around the axis of the hinge 8 against the force of the spring. In other words, it rotates until it comes into contact with the back surface of the shelf 4, but it may be fixed directly to the pedestal 6 a without the intervention of the spring hinge 8. The reason is that the fall prevention member 7 is formed to be extendable and contractible.

[0023] Thus, the fall preventing member 7 is the lower end surface of the base body 7b is always force - on the upper surface C ₁ of the cartridge C so contacting posture is maintained, the force - cartridge C, upon storage The front and rear surfaces C ₂ and C ₃ are standing wall portions 5c and 5d of the tray 5, respectively.
And the upper and lower surfaces are constrained by the bottom plate 5e and the lower end 7a of the fall prevention member 7, so that the shelves 4 drop out of the tray 5 due to swinging or vibration applied to the shelf plate 4. Things will be gone.

Therefore, in order to take out the above-restricted cartridge C, the fall prevention member 7 is pushed by the hand and flipped up, or the lower end surface of the base 7b is spring-loaded.
If it is pushed upward against the force of 7c, the fall prevention member 7
, And can be taken out in the same way as the original tray.

Next, the fall prevention member 7 is connected to one shelf 4
In the case where two rows are provided before and after, that is, when the dedicated tray 5 is a so-called double type in which two rows are provided before and after the shelf plate 4, it is attached via a spring hinge 8 although not shown in the drawing. The front and rear two rows of fall prevention members 7 and 7 are pivotally connected by connecting links (not shown) to form two fall prevention members 7 and 7 as parallel links. If pressed, the other fall prevention member 7 can be moved together with it.

The above-mentioned structure is required when the cartridge C housed in the tray 5 on the back side of the dedicated tray 5 of the front and rear double type is inevitably connected to the fall prevention member 7 on the near side and the back side. If both of the fall prevention members 7 are not flipped up, the car
This is convenient when the carriage C cannot be moved in and out.

Although the fall prevention member 7 in the above embodiment is formed by the upper plate 7a and the base 7b, in the present invention, the fall prevention member 7 does not necessarily have to be formed as described above.

That is, in each of the above-mentioned fall prevention members 7, the lower end surface thereof abuts against the upper surface of the cartridge row in a hanging state, thereby preventing the cartridge from jumping out and falling. A member that can be substituted for the fall prevention member 7 only needs to have a portion corresponding to the lower end side of the fall prevention member 7. This is shown in FIGS.

In the embodiment shown in FIG. 4, the fall prevention member 7 is composed of two plates 71 and 72.
The upper and lower sides of the other plate 72 are provided with screws 72a for loose insertion into the long holes 71a. After the height of the plate 71 is adjusted by moving the plate 71 up and down, the thumb screws 71b and the like are screwed and tightened to the screw 72a to unite the two plate members. This makes it possible to cope with the difference in the size of the cartridge C by changing the length of the fall prevention member 7 in the vertical direction.

FIG. 5 shows a structure in which the fall prevention member 7 is composed of one main plate member 73 and three sub plate members 74, 75, 76. Each of the plate members is configured so that the total width becomes the same as the width of the main plate 73.
Thus, elongated slots 73a, 73b, 73c are provided vertically on both lower sides of a portion of the main plate 73 corresponding to the sub-plates 74, 75, 76, and screws are provided on both upper sides of the sub-plates 74, 75, 76. 74a, 75a, 76a
The screw 74a in the long hole 73a, the screw 75a in the long hole 73b,
The screws 76a are loosely inserted into the long holes 73c, and the respective screws project from the surface of the main plate. The sub plates 74, 75, and 76 are moved up and down to adjust their heights. All the plate materials are united by screwing and tightening to each screw. By doing so, the longitudinal length of the fall prevention member 7 can be partially changed to correspond to the shape of the cartridge C having various sizes.

4 and 5 are attached to the lower surface of the shelf 4 by spring hinges 81. Further, the base 7b shown in FIG.
It may be formed in a split type as shown in FIGS. This makes it easy to accommodate cartridges of different sizes stored in the same shelf.

[0032]

[Effects of the Invention] The present invention is as described above. The front / rear sliding is restrained and prevented by a rack or a bookshelf, and the storage object to be placed and stored is pressed from above. Since the fall prevention member to be supported is provided on the back surface of the upper shelf plate so as to be able to expand and contract, or to be flipped up and down, the stored object is prevented from sliding back and forth, and is also restrained from above and below. Therefore, even if a large shake or vibration due to an earthquake or the like is applied to the shelf side, the stored items are approximately in a dedicated tray or
There is no risk of jumping out of the shelf or falling.

Further, when taking out and re-storing the stored items, the above-mentioned fall prevention member is expanded or contracted or flipped up, which is equivalent to a state where the fall prevention member is not provided. There is a special effect that there is no hindrance.

Further, the fall prevention member can be attached to the shelf body simply by fixing it to the back surface of each shelf plate via a hinge or the like, or by flipping up and hanging it down, so that the structure is simple and the handling is simple. In terms of cost and operation, there is an advantage not found in conventional products.

Further, since the fall prevention member has an upper and lower telescopic structure, it can follow the size and height difference of a cartridge or the like to be stored as it is, and this telescopic structure is provided in the front width direction of the fall prevention member. Even if cartridges of different sizes are stored on the same shelf,
It can be prevented from dropping by contacting each storage item.
