【Example】

 An embodiment of the present invention will be described below with reference to FIGS. 1 to 7. First, in FIGS. 3 to 5, the pair of columns 11 are connected to each other by a horizontal frame 12, and a leg frame 14 having casters 13 is attached to a lower end portion thereof. The shelf 11 has three shelves 15, 16 and 17 attached at different heights. Although these shelves 15, 16 and 17 have different sizes, they have the same configuration, and thus the shelf 15 will be described as a representative of these.

Next, in FIGS. 1 and 2, inside the pair of support columns 11, a cylindrical pivot portion 18 is provided in the upper portion, and a locking pin 19 is provided below the pivot portion 18. Two brackets 20 are attached to both sides of the lower surface of the shelf plate 15. Each bracket 20 has a pivot shaft 21 attached to a base end portion protruding rearward from an end portion of the shelf plate 15. The pivot shaft 21 is rotatably connected to the pivot support portion 18 of the column 11. There is. A connecting shaft 22 is attached to each bracket 20 at a position closer to the tip than the pivot shaft 21, and an upper end of a supporting piece 23 is rotatably attached to the connecting shaft 22. It

The lower ends of the two support pieces 23, 23 are integrally connected by a connecting member 24, and the lower side surface 23 a of the support piece 23 is in contact with the upper surface of the locking pin 19 by its own weight. A plurality of, for example, four locking recesses 25, 26, 27, 28 are formed on the lower side surface portion 23a of the support piece 23, and the locking pin 19 is locked in the inner portion thereof. When the support piece 23 is pushed in the direction of arrow A, the inclination of the surface portions 25a, 26a, 27a, 28a on the upper side (left side in FIG. 1) of the locking recesses 25, 26, 27, 28 is not fixed. The angle is set to prevent the support piece 23 from rotating in the direction of the arrow B by hitting the stop pin 19, and the inclination of the lower surface portions 25b, 26b, 27b (the right side shown in FIG. 1) depends on the support piece 23. Is pulled in the direction opposite to the arrow A, it is moved along the locking pin 19 and the supporting piece 23 is rotated in the direction indicated by the arrow B.

As shown in FIG. 2, the locking recess 29 is formed at the upper end of the support piece 23 and laterally engages with the locking pin 19 when the shelf 15 is closed. When the support piece 23 is pulled in the direction of arrow C, the locking recess 29 strikes against the locking pin 19 to prevent the support piece 23 from rotating in the direction of arrow B.

Next, the structure of the front end portion of the shelf board 15 will be described. As shown in FIG. 6, the regulation plate 30 has an S shape and is attached to the lower surface of the front end portion of the shelf board 15. The rotating shaft 31 is in the shape of a rectangular tube and is located on the lower surface of the shelf plate 15 and is applied to the regulating plate 30. The press-contact plate 32 is made of an elastic material and has an end bent into an L shape, and is attached to the lower surface of the shelf plate 15 to press the rotary shaft 31 to the regulation plate 30.

In the commodity fall prevention frame 33, the connecting member is bent into a U shape, a horizontal rail 33a is installed on the side surface of the open end, and a plurality of vertical rails 33b are provided between the horizontal rail 33a and the upper end. It is installed. The commodity drop prevention frame 33 is attached to the rotating shaft 31 by bending the lower end portions on both sides by about 90 degrees and penetrating through a hole 34 formed in the shelf board 15. When the commodity fall prevention frame 33 is used, as shown in FIG. 6, the commodity fall prevention frame 33 is erected so as to be orthogonal to the shelf board 15 and the horizontal rails 33a come into contact with the upper surface of the shelf board 15. As shown in FIG. 7, when the upper end portion is rotated in the direction of arrow D, the rotating shaft 31 rotates while deforming the pressure contact plate 32 and in contact with the regulation plate 30, and the corner portion passes through the pressure contact plate 32 1. At this point, the product fall prevention frame 33 is pressed against the regulation plate 30 and held in a stored state in which it is parallel to the shelf plate 15.

Next, the operation of the above configuration will be described. From the closed state of the shelf plate 15 shown in FIG. 2, the connecting member 24 is once rotated in the arrow E direction to release the locking pin 19 from the locking recess 29. Then, when the shelf board 15 is rotated in the upward direction (the direction opposite to the arrow A), the supporting piece 23 is urged downward by its own weight and the weight of the connecting member 24, so that the lower side surface portion 23a thereof moves onto the locking pin 19. It is placed. When the shelf plate 15 is subsequently rotated upward, when the locking recess 25 is aligned with the locking pin 19, the support piece 23 is moved from the top to the bottom, and the locking recess 25 is aligned with the locking pin 19. Lock. If the rotation of the shelf plate 15 is stopped at this point, the support piece 23 is urged in the direction of arrow A by the weight of the shelf plate 15. In this case, the upper surface 25a of the locking recess 25 is locked to the locking pin 19 to prevent the support piece 23 from rotating in the direction of the arrow B, so that the shelf plate 15 is set at a predetermined angle, for example, a horizontal line. On the other hand, it is supported at an inclination angle of 60 degrees.

Next, when the shelf plate 15 is rotated further upward, the lower surface portion 25 b of the locking recess 25 moves along the locking pin 19 and the supporting piece 23 is rotated in the direction of arrow B. While moving, the locking pin 19 comes out of the locking recess 25 and is automatically locked in the locking recess 26 arranged thereunder. Here, if the rotation of the shelf board 15 is stopped, the shelf board 15 is supported at a predetermined angle, for example, an inclination angle of 40 degrees with respect to the horizontal line, as described above. Similar to the above, when the shelf plate 15 is further rotated upward, the locking pin 19 is released from the locking recess 26 and locked in the locking recess 27, so that the shelf plate 15 is moved relative to the horizontal line. It is supported at a tilt angle of 20 degrees. When the shelf plate 15 is further rotated upward and the locking pin 19 is locked in the locking recess 28, the shelf plate 15 is supported horizontally.

In order to close the shelf board 15, first, the upper end of the commodity fall prevention frame 33 is rotated in the direction of arrow D to be in a retracted state in which it is parallel to the shelf board 15, as shown in FIG. Next, the connecting member 24 is rotated in the direction of arrow E to release the locking pin 19 from any one of the locking recesses 25, 26, 27 and 28. Then, when the shelf plate 15 is rotated right below, the shelf plate 15 becomes parallel to the support column 11, and the locking pin 19 engages with the locking recess 29. Here, when the shelf plate 15 is pulled in the opening direction, that is, the front direction, the upper end portion of the support piece 23 is also pulled in the arrow C direction shown in FIG. However, since the locking recess 29 hits the locking pin 19 to prevent the support piece 23 from rotating in the direction of the arrow B, the shelf board 15 stops at the position indicated by the chain double-dashed line, and no more. It is prevented from opening.

According to the above embodiment, the following effects can be obtained. That is, when the shelf plate 15 is rotated upward from the closed state, the supporting recesses 23, 26, 27, 28 are sequentially locked from above by the weight of the supporting piece 23 and the connecting member 24. Since the shelf plate 15 is held at a desired tilt angle by being locked to the pin 19, the locking shafts 5, 9 are pulled out from the locking recesses 4, 8, and the tilt angles of the shelves are adjusted. The operation is remarkably easier than the conventional example in which two steps of locking the recesses 5 and 9 in the recesses 4 and 8 are performed.

2. In the above embodiment, since the locking recess 29 is provided, when the shelf plate 15 is closed, the locking pin 19 engages with the locking recess 29 and the shelf plate 15 is opened carelessly. Since this is prevented, the shelf plate 15 does not open during the movement to cause an accident. 3. In the above embodiment, since the support pieces 23, 23 are integrally connected by the connecting member 24, the support pieces 23 on both sides of the shelf plate 15 can be easily operated at the same time. It is possible to increase the downward urging force to secure the locking of the locking recesses 25, 26, 27 to the locking pin 19. 4. Since the product fall prevention frame 33 can be folded, the product fall prevention frame 33 is not lost when the bookshelf device is used and stored in a warehouse or the like, and is not lost.
