Description

[Detailed description of the device]

[0001]

[Industrial application] The present invention, when a product storage case is placed on a display shelf whose shelf plate is inclined rearward and downward, aligns the front surface of the case without unevenness, and the case slides backward during use. The present invention relates to a device that prevents falling.

[0002]

2. Description of the Related Art A display shelf for displaying, for example, packed milk or the like in a storage case in two rows in a front and rear direction with the opening surface of the case facing forward and upward so that the product is easy to see and does not fall. There is.

As shown, a shelf board (2) of a display shelf (1)
Is usually in the shape of a rectangular frame, the case (3) is usually made of synthetic resin, and a plurality of reinforcing ribs (4) are projected at both upper and lower ends (left and right ends in the drawing) of the outer peripheral surface of the case (3). A concave groove (5) is formed between the ribs (4) that are provided and adjacent to each other. (6)
Is a milk pack.

[0006] In this display rack (1), the case (3) in the front row may be retracted due to vibration or shock during use. Especially, the movable display rack (1) provided with casters (7) is However, this tendency is large, and the front surface of the case (3) is uneven, which is very unsightly.

FIG. 5 to FIG. 7 show an example of means conventionally implemented to solve the above-mentioned problems.
Pins (8) for locking are provided on the front and rear of the upper surface of the shelf (2).
And a stopper (9) is projected.

As shown in FIGS. 6 and 7, in the case (3) in the front row (left side in FIG. 6), the engaging pin (8) engages with the groove (5) from below, The case (3) in the rear row is prevented from moving backward and the case (3) in the rear row is prevented from moving backward and falling by the stopper (9). When the case (3) in the front row becomes empty, the case (3) is removed, the case (3) in the rear row is pulled out, and the groove (5) is locked to the locking pin (8).

[0007]

In the above-mentioned display rack (1), since the locking pin (8) is fixed to the shelf plate (2), when the case (3) is taken in and out, or the case in the rear row. When locking (3) in the front row, it is necessary to slightly lift the front part of the case (3) so that the case (3) does not collide with the pin (8). Also, the case (3), which contains a lot of milk packs (6), etc., is heavy, so it is difficult to handle.

This problem is similarly recognized when the pin (8) is replaced with a downward U-shaped locking member.

[0009]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention pivotally installs a locking member rotatable around a left and right axis at a front end of a shelf board, and places the locking member at a proper position. , When it is rotated upward, it is supported by the front surface of the shelf board, the upper end of which projects above the shelf board, and which is provided with a locking projection that engages with the recessed portion of the front end of the lower surface of the product storage case placed on the shelf board. A stopper is provided upright on the rear end of the upper surface of the plate.

[0010]

In the device of the present invention, with the locking projection of the locking member facing downward, the case is pushed in or pulled out until the groove at the front end of the lower surface of the case is located above the front end of the shelf board.
If the locking projection is directed upward and then the case is pushed in until it stops, the rib of the front end of the lower surface of the case is locked by the locking projection and the case is prevented from moving backward.

When the case in the above-mentioned state is pulled out, the locking projections that face upward are automatically rotated by the ribs of the case immediately after that, the locking projections face downward, and the case Be withdrawn.

[0012]

1 to 4 show an embodiment of the present invention. As shown in FIG. 1, the display rack (1) has a rectangular frame-like rear lower portion corresponding to the above (2). A large number of shelf plates (11) that are inclined to are fixedly installed.

The front-rear length of the shelf plate (11) (left-right length in FIG. 1) is slightly longer than twice the front-rear length of the case (3) with the opening surface facing forward, and slightly longer than the front plate (11a). Both ends of a locking rod (12) which is a horizontal locking member immediately before the front plate (11a) are pivotally supported at the front end of the side plate (11b) protruding forward.

At the center of the locking rod (12), the above-mentioned locking pin
A mountain-shaped bent portion (12a), which is a locking protrusion corresponding to (8), is bent, and when it is turned upward, it is slightly tilted backward and the front plate
It is stably supported by the front upper end of (11a), and the upper end of the bent portion (12a) projects slightly above the front plate (11a).

A stopper (13) corresponding to the stopper pin (9) is provided upright at the center of the upper surface of the rear plate (11c) of the shelf plate (11).

As shown in FIG. 2, the shelf board (11) described above has the milk pack (6) in which the bent portion 12a of the locking rod (12) is hung down.
Put the case (3) filled with the
In the case of (3), the rear end comes into contact with the stopper (13) and stops, and further backward movement is prevented.

Then, as shown in FIG. 2, a case (3) filled with a milk pack (6) is attached to the same shelf plate (11) as a groove (5).
Is pushed in until it is located in the front upper part of the front plate (11a), and as shown in FIG. 3, the bent portion (12a) is rotated upward by using the groove (5), and the front plate (11a) is rotated. Lean on.

When the case (3) is pushed in a little more,
As shown in Fig. 7, the rib (4) at the front end of the lower surface of the case (3) abuts the bent portion (12a), and a slight space is formed between the case (3) and the rear case (3). , Locked in place in a non-retractable manner.

Thus, when the milk pack (6) in the front case (3) locked to the shelf plate (11) is sold out and emptied, the bent portion (12a) is Immediately after that, the rib (4) automatically rotates and hangs down as shown in FIG. 2, and the case (3) is pulled out from the shelf plate (11) all at once.

Then, after pulling out the case (3) in the rear row to the state shown in FIG. 2, the bent portion (12a) is turned upward as shown in FIG. 3 and the case (3) is slightly pushed in. , Fig. 3
In this state, the case (3) is locked in a predetermined position in the front row so that it cannot be retracted.

In the above description, a mountain-shaped bent portion (12a) is provided in the center of the locking rod (12) as a means for preventing the front row case (3) from retracting, but the locking rod (12) is not provided. U-shaped bends may be provided at two places on the left and right of the rack, or instead of the locking rods (12), the super plate is placed at a suitable position on the front surface of the front plate (11a) of the shelf plate (11), one piece of which is vertically moved. It may be fixed so that it can rotate.

Further, the present invention can be applied without any problem even when the shelf plate is plate-shaped.

[0023]

As described above, the device of the present invention does not require the front portion of the heavy case to be lifted when the case filled with the products is fixed to the predetermined position of the front row of the shelf plate in a non-retractable manner.

When pulling out an empty case,
Since the engagement between the case and the locking member of the shelf plate is automatically released by hand, the case can be easily taken in and out.
