[Detailed description of the device]

[0001]

[Industrial application] The present invention is a drop for preventing stored items such as cartridges placed and stored in dedicated trays provided on shelves such as racks and bookcases from falling due to shaking or vibration due to an earthquake or the like. It relates to a prevention mechanism.

[0002]

2. Description of the Related Art Conventionally, a cartridge tray (hereinafter referred to as a dedicated tray) formed so that a cartridge type magnetic tape or the like (hereinafter referred to as a cartridge) can be placed and stored exclusively on a rack or a shelf board of an article shelf. Has been used.

As an example of this dedicated tray, as shown in FIG. 7, a bottom plate B of a tray body T having a substantially upright shape is
The mounting surface b ₁ is formed to incline downward from the intermediate portion in the depth direction toward the side facing the side, and the front side thereof is an inclined surface or concave stepped portion b ₂ opposite to the inclined surface b _1. And the cartridges C of the same shape are placed side by side between the both side plates S ₁ and S ₂ of the main body T to be placed and stored. Note that Fp and Bp are front and rear standing walls of the tray body T.

In order to take out each cartridge C from the tray T, a finger is put on the front upper surface C ₁ of the cartridge, and the cartridge C is slightly raised toward the front side with the top t of the inclined surface b ₁ as the center. When the front surface C ₂ of the raised cartridge C is located further in front of the front surfaces of the other cartridges C, the raised cartridge is grasped and taken out by hand.

Generally, in a storage rack for books, tape reels, etc., the books and tape reels in a stored state so that the stored items do not drop even if shaking or vibration such as an earthquake is applied to the rack. It suffices to attach a fall prevention fence or a similar structure to the front and back of the container, but like the above-mentioned cartridge-only tray, pull the stored items forward with your fingers to move them in and out. In the case of a model type, if a thing such as a fall prevention fence is installed on the front side of the stored item, there is a problem that it cannot or cannot be put in and out.

[0006]

SUMMARY OF THE INVENTION Therefore, the problem to be solved by the present invention is that a cartridge or the like placed on a special tray of a type in which a stored item is pulled up to the front side with a finger and taken out is dropped or dropped. The challenge is to develop a fall prevention mechanism.

[0007]

The structure of the present invention made for the purpose of solving the above-mentioned problems is to provide a special tray of a type in which stored articles of the same shape such as a cartridge are vertically rotated and pulled out to be taken out. In the article placing shelf having, a fall prevention member is constantly urged in a hanging posture via a shaft with a spring along the length direction of the shelf plate above the tray and is rotatably suspended around the shaft. It is characterized in that the lower end of the fall prevention member is formed so as to abut against the upper surface of the stored item.

In FIGS. 1 and 2, reference numerals 1 and 2 denote columns of an article placing shelf, and 3 denotes slots formed in the right and left side views of the columns 1 and 2 at equal pitches in the height direction. 4, the bracket claws (not shown in the figure) provided outwardly on the left and right ends of 4 are fitted and held, and the shelf board 4 is erected and held on the columns 1 and 2, and the columns 1 to 4 are mainly An example of the article placing shelf is formed as a member.

The drop prevention mechanism of the present invention is
Since this is applied when the dedicated tray 5 for the cartridge is formed, the dedicated 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, for example, the structure shown in FIG.
This tray 5 is viewed from the front, and has the left and right side plates 5 on the left and right ends.
a and 5b, and a plurality of partition plates (not shown in the figure) in the middle of them, and standing wall portions 5c and 5d that serve as front and rear stoppers, and the cross section is formed in a substantially stepped shape. A bottom plate 5e is arranged between the left and right plates 5a and 5b so that the front and rear are sandwiched by the standing walls 5c and 5d.
Here, the front and rear standing wall portions 5c and 5d are on the front side (entrance side).
Is formed so that the lower side (back side) is higher. In addition, the bottom plate 5e having a stepped shape has a protruding portion 5f formed at a position approximately 1/3 in the front in the depth direction. There is also a special tray that does not have the partition plate.

In the embodiment of FIG. 1, the special tray 5 is
With respect to one shelf board, two rows are arranged in the same direction, overlapping front and rear, and a plurality of them are arranged in the length direction. For this reason, since the plurality of trays 5 located on the article loading / unloading side of the shelf board 4, that is, on the front side are slidable in the length direction of the shelf board 4, at least one tray is less than the tray row in the rear row. Will be placed.

[0013] It is very important that the shelf board 4 is used for loading and unloading articles.
If it is made from both front and rear sides, the row of trays 5 on the rear row side is provided back to back with the row of trays on the front side, so the number of rows of trays on the front side can be reduced,
It does not have to be slidable.

If the shelf board 4 has a so-called single width in which the trays 5 can be installed in only a single row, the tray 5 can be installed in only one row toward the article loading / unloading side, so that it is not necessary to slide it. Absent. In the shelf board 4 of FIG. 1, 4a and 4b are locking projections for the dedicated tray 5 which are formed upright along the front and rear sides of the shelf board 4.

The above description is an example in which the dedicated tray 5 is placed on the shelf board 4 to be formed.
Can be integrally formed with the shelf plate 4, and can be arbitrarily selected to be a separate body or a single body. Further, the shape and structure of the dedicated tray 5 are not limited to those shown in FIG. For example, the tray shown in FIG. 7 or a tray having a cross-sectional shape other than that may be used.

On the special tray 5 arranged on the upper surface of each shelf 4 as described above, the cartridges C having the same shape shown by the broken line in FIG. 1 are placed side by side. This cartridge C
Contains a magnetic tape or the like having various data recorded therein, and a large number of them are arranged and stored in the special tray 5 as described above. The bottom plate 5e of the tray 5 has a stepwise sectional shape. Accordingly, the cartridges C are arranged in a state where the front side C ₃ is supported by the tray 5 at three points P ₁ , P ₂ and P _{3 on} the front surface C ₃ and the bottom surface C ₄ .
In addition to the above-mentioned cartridge C, the exclusive tray 5 of the present invention is
Video cassette, audio cassette, CD cassette,
It may be a tray for articles such as books that can be arranged in an upright posture. And all the cartridges C are all the same size and lined up in the same posture,
In order to take out one of the cartridges C, the front side of the upper surface C ₁ of the cartridge C is pressed with a finger, and the cartridge C is rotated to the front side with the apex of the convex portion 5f as a fulcrum, and the cartridge C is removed from the row. The cartridge C is taken out in a posture in which it can be picked and grasped.

In order to take such a take-out mode, even if the fall prevention means is provided, simply providing a movable fence-like object on the take-out side makes the take-out operation troublesome.

Therefore, the present invention is provided with a mechanism that abuts against or presses the upper surface C ₁ of the stored cartridge C so that the shelves 4 do not pop out or fall even if they shake or vibrate. I did it. Next, a description will be given of an example of this falling portion prevention mechanism.

Reference numeral 6a designates a mechanism mounting pedestal provided on the lower surface of the shelf plate 4 immediately above the shelf plate 4 provided with the dedicated tray 5. Here, a channel material or the like having an appropriate cross section is provided on the shelf plate 4. It is formed by being attached to the back surface via a horizontal cross-shaped attachment member 6b. Reference numeral 7 denotes an abutment plate attached to this pedestal 6a via a spring hinge 8 so as to be able to rotate angularly in the front-rear direction of the shelf plate 4 (here, toward the rear side of the shelf plate 4), and its lower end in the hanging position. a space edge 7a is formed between the rear surface of the upper surface C ₁ cartridge column C of the plate-like member abutting height housed side by side when viewed from the front of the shelf in its upper shelf 4 of the cartridge C It is provided in a manner like a closing curtain plate.

However, the abutting plate 7 is always kept in a suspended posture by the action of the spring of the spring hinge 8 here, and if it is pushed to the opposite side by hand or the like, the force of the spring 8 resists the force of the spring. Rotate about 90 degrees about the axis. That is, it rotates until it comes into contact with the back surface of the shelf plate 4.

Thus, the contact plate 7 has its lower end 7a.
However, since the attitude of contacting the upper surface C ₁ of the cartridge C is always held by the spring force, the front and rear surfaces C ₂ and C _{3 of the} cartridge C are restrained by the standing wall portions 5c and 5d of the tray 5 during storage. Moreover, since the upper and lower surfaces are restrained by the bottom plate 5e and the lower end 7a of the contact plate 7, the swinging and vibration applied to the shelf plate 4 prevent the tray 5 from jumping out or dropping. Of.

Therefore, in order to take out the cartridge C which is constrained as described above, if the contact plate 7 is pushed to the opposite side by hand and flipped up, the plate 7 is not present, so that it is taken out from the original tray. It can be taken out in the same way.

Next, when the abutting plates 7 are provided in two rows in the front and rear with respect to one shelf plate 4, that is, the exclusive tray 5
However, in the case of a so-called double type in which two rows are provided in front of and behind the shelf board 4, as shown in FIG.
7 is pivotally connected by a connecting link 9 and is pushed toward the one contact plate 7 so that the other contact plate 7 can be rotated.

With the above construction, when the cartridge C stored in the tray 5 on the back side of the special tray 5 of the front and rear double type is put in and out, the contact plate 7 on the front side and the contact plate on the back side are inevitable. This is convenient when the cartridge C cannot be put in and out unless both of them are flipped up.

Although the contact plate 7 in the above embodiment is formed of a plate-shaped member, the contact plate 7 is used in the present invention.
Need not necessarily be formed of a plate-shaped member. That is,
Since the lower end 7a of each of the contact plates 7 is in contact with the upper surface of the cartridge row in a suspended state, the contact plates 7 can be replaced by the contact plates 7 because they prevent the cartridges from jumping out and falling. It suffices that the member has a portion corresponding to the lower end side of the contact plate 7. For example, in FIG.
Is a front view of an abutment member corresponding to the abutment plate 7 formed by an abutment frame body 71 having an abutment side 71a at the lower end. The frame body 71 is attached to the shelf board 4 by a spring hinge 81 in the same manner as in the above example. If it is attached to the lower surface of, the same function as that of the contact plate 7 is exerted. Further, since the other side of the frame 71 can be seen through, it is convenient for assuring the storage state of the cartridge on the back side and the display of the cartridge.

The contact plate 7 or the frame body 71 is urged by the action of the springs of the spring hinges 8 and 81 so as to always maintain the hanging posture.
In order to keep the flip-up posture as it is, it is necessary to support the contact plate 7 with a human hand. For this reason, only one free hand can be used to insert and remove the cartridge, which is inconvenient when the number of cartridges is large.

In view of this point, in the present invention, there may be added a mechanism capable of holding the flip-up posture of the contact plate 7 or the contact frame 71 without manpower. An example of this mechanism will be described with reference to FIGS. 5 and 6, 1
Reference numeral 0 is a snap button which is provided in the middle of the contact plate 7 from the front side to the back side, and 10a is a knob on the front side and 10b is the contact plate 7.
It is an elastic bulge that is projected to the back side of the.

When the abutting plate 7 having the button 10 is flipped up, the lower surface of the shelf plate 4 facing the bulging portion 10b of the button 10 has a portion 1 for receiving the bulging portion 10b.
A receiving hole 11 having a diameter slightly smaller than 0b is formed.

When the bulging portion 10b is press-fitted into the receiving hole 11 with the above structure, the abutting plate 7 is held in the rebounding posture by the fitting between the elastic bulging portion 10b of the button 10 and the receiving hole 11. It

The function of holding the contact plate 7 in the flip-up posture as described above is related to the relationship between the magnet provided on the back surface of the plate 7 and the magnetizability of the back surface of the shelf plate 4 corresponding to this magnet, and the function of the surface fastener. It can also be exerted by the relation of attachment and detachment, or the frictional action or the stopper function provided between the shaft of the spring hinge 8 and the metal fitting. Which one should be adopted may be determined by looking at the material and structure of the shelf board.

The function of holding the flip-up posture as described above saves labor even when the dedicated tray 5 is installed or when all the cartridges are put in and taken out at one time, such as at the time of inventory. It is possible to get in and out of it.

[0032]

The present invention is as described above, and it is possible to press the top or the top of an item to be stored in the rack or bookshelf which is restrained and prevented from sliding forward and backward from above. Since the abutting member to be supported is hung on the back surface of the upper shelf so as to be constantly urged to the drooping posture by the action of the spring, it is possible to lift it from the drooping posture.
In addition to being prevented from sliding back and forth, the stored items are also restrained from above and below. Even if a large shake or vibration is applied to the shelf side due to an earthquake, etc. There is no risk of jumping out of the shelf or falling. Further, when taking out or re-holding the stored items, the contact member is flipped up so that the state is the same as the state without the contact member. Therefore, there is no problem in taking in and out of the stored items. effective. Further, the abutting member can be attached to the shelf body by simply flipping up a plate-shaped or frame-shaped member on the back surface of each shelf plate via a hinge or the like and attaching it to the shelf body, so the structure is simple and the handling is simple. As described above, there are advantages over conventional products in terms of cost and operation.
