Description

[Detailed Description of the Invention] [Industrial Field of Application] This invention relates to a stopper device for an inclined shelf that sequentially takes out items from the lower-level side end.

[Conventional technology]

Conventionally, as a stopper device for an inclined shelf that is inclined diagonally downward from the rear to the front, as disclosed in Japanese Utility Model Application Publication No. 175343/1983, a stopper device is installed at the front end of the inclined shelf. It is known to provide a fixed stop with a load-locking surface perpendicular to the direction of extension.

[Problems to be Solved by the Invention] In the case of the conventional stopper device for a sloped shelf, a stopper having a load-locking surface perpendicular to the extending direction of the sloped shelf is fixed to the sloped shelf, and the load is not fixed to the load-locking surface. Since it is in pressure contact with the stop surface, there was a problem in that it was difficult to pull up the luggage upward from the inclined shelf.

The object of this invention is to provide a stopper device for an inclined shelf that can easily pull up cargo upward from an inclined shelf having a stopper.

[Means to solve the problem]

In order to achieve the above-mentioned object, in the stopper device for a sloped shelf of the present invention, a baggage locking surface 2 which is a flat surface at the rear is provided at the front end of the sloped shelf 1 which slopes diagonally downward from the rear to the front. The front part of the stopper 3 is pivotally connected to the front end of the inclined shelf 1 by a support shaft 4 extending in the left-right direction at a level lower than the front part of the load bearing surface of the inclined shelf 1. A support part 5 is provided to stop the baggage at the locking position, and a biasing means for rotating the rear part of the stopper 3 in a downward direction acts on the stopper 3. When the stopper 3 is supported by the support part 5, the load is The locking surface 2 is configured to be perpendicular to the load bearing surface of the inclined shelf 1.

〔Example〕

Next, this invention will be explained in detail using illustrated examples.

Figures 1 to 3 show a first embodiment of this invention. The frame members 6 are arranged so as to extend in parallel at intervals in the left-right direction, and both ends and the middle lower part of each inclined frame member 6 are connected via a connecting member 7, and a large number of frames extend in the left-right direction. The load-receiving rollers 8 are arranged at intervals in the longitudinal direction between the inclined frame members 6 and are rotatably installed on the respective inclined frame members 6, and the upper part of each roller 8 is connected to each inclined frame member. The inclined shelf 1 is formed by the inclined frame members 6, the connecting members 7, and the rollers 8, which protrude by the same height from the upper surface of the inclined frame members 6.

The plurality of inclined shelves 1 configured as described above are installed and fixed on the support frame 9 at intervals in the vertical direction, and on the outside of the front end of each inclined frame member 6 in the inclined shelf 1, there is a rear part from a plane. A stopper 3 is disposed, and the front part of the stopper 3 extends in the left-right direction at a slightly lower level than the front part of the load-bearing surface, which is a plane including the upper part of each roller 8. It is pivotally connected to the inclined frame member 6 by an extending support shaft 4, and a support portion 5 for stopping the stopper 3 at the locking position is integrally provided at the front end of the inclined frame member 6.

One end of a biasing member 10 made of a helical spring fitted to the support shaft 4 is engaged with the inclined frame member 6, and the other end of the biasing member 10 is engaged with the stopper 3.
, and the stopper 3 is rotated by the biasing member 10 to the locking position, that is, the position where it abuts against the support part 5. When the stopper 3 is in the locking position, the load is locked at the stopper 3. Side 2
is configured to be perpendicular to the load bearing surface of the inclined shelf 1.

When a large number of items 11A to 11E are placed on the inclined shelf 1, each item comes into close contact with each other due to the diagonally downward forward movement force based on its own weight, and the front surface of the item 11A at the forefront is stopped by the stopper 3. It is pressed against surface 2 and locked in place.

Next, when the frontmost baggage 11A is pulled up, the frictional force between the baggage 11A and the stopper 3 tends to rotate the stopper 3 in the direction of arrow A, that is, in the direction in which the baggage retaining surface 2 moves away from the baggage 11A. Therefore, the baggage 11A can be easily pulled out. The moment the frontmost item 11A comes off the stopper 3, the force of the biasing member 10 rotates the stopper 3 to the locking position and holds it at that position. , the second and subsequent loads 11B to 11E move diagonally downward and the front surface of the second load 11B is locked by the load locking surface 2 of the stopper 3.

FIG. 4 shows a second embodiment of this invention, in which the frontmost baggage 1 is placed at the rear lower part of the stopper 3.
When the front surface of 1A hits the baggage retaining surface 2,
A locking arm 12 located at the bottom of the luggage 11A is integrally provided, but the other configurations are the same as in the first embodiment. In the case of the second embodiment, even if the load placed on the rear of the inclined shelf 1 rapidly moves forward on the inclined shelf 1 and collides with the stopper 3,
The rotation of the stopper 3 in the direction of arrow A due to the collision is as follows:
Since this is prevented by the engagement between the locking arm 12 and the load 11A, it is possible to prevent the rapidly moving load 11A from moving forward beyond the normal position while rotating the stopper 3. Further, even if the baggage 11A collides with the stopper 3 and jumps up, and the stopper 3 rotates in the direction of arrow A, the rotation of the stopper 3 is limited by the engagement between the locking arm 12 and the baggage 11A, Moreover, when the luggage 11A is lowered onto the inclined shelf 1, the stopper 3 is rotated by the luggage 11A to the normal locking position via the locking arm 12, so that the luggage 11A is locked in a predetermined position. be able to.

When implementing this invention, the biasing member 10 made of a helical spring may be omitted and the biasing member 10 made of a weight may be suspended from the stopper 3 as shown in FIG. As shown in the figure, the stopper 3 may be configured to be rotated to the locking position and held at that position by a biasing means based only on its own weight.

[Effect of idea]

This idea is structured as described above, so
This produces the effects described below.

At the front end of the inclined shelf 1, which is inclined diagonally downward from the rear to the front, the front part of the stopper 3, which is provided with a flat cargo retaining surface 2 at the rear, is located in front of the cargo supporting surface of the inclined shelf. A support part 5 is provided at the front end of the inclined shelf 1 to stop the stopper 3 at a locking position, and the support part 5 is pivoted by a support shaft 4 extending in the left-right direction at a lower level than the support part 4. When the stopper 3 is supported by the support part 5, the load retaining surface 2 is perpendicular to the load supporting surface on the inclined shelf 1. Therefore, when pulling up the frontmost load 11A that is in pressure contact with the load retaining surface 2 of the stopper 3, the stopper 3 is rotated by the frictional force between the load 11A and the stopper 3, but the rotation Since the moving direction is the direction in which the luggage retaining surface 2 moves away from the luggage 11A, the frontmost luggage can be easily pulled up, and the luggage retaining surface 2 is a plane perpendicular to the luggage supporting surface on the inclined shelf 1. Therefore, stopper 3
Effects such as being able to prevent damage to the baggage by increasing the contact area between the bag and the baggage can be obtained.
