Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a multi-tiered pallet that holds various articles stacked in multiple tiers.

[Prior Art and Problems] In a system in which a plurality of pallets are arranged on a frame in the form of multi-stage shelves so that, for example, a sheet-like article can be placed on each pallet, a working space is secured above each pallet. Therefore, in the past, each pallet is pivotally supported by a frame at its rear edge, so that when the front edge of the pallet is lifted, the pallet changes from a horizontal position to a rearwardly tilted position. That is, a multi-tiered pallet devised for such a purpose is disclosed in Japanese Utility Model Application Publication No. 55-335 filed by the present applicant. However, in this conventional multi-stage pallet, the rearward tilted position (elevation angle) of the pallet is changed by engaging an engagement pin provided on one rear edge of each pallet with an obliquely upward elongated hole provided in the frame. Since it was a holding mechanism, it was necessary to pull the pallet diagonally upward in order to return the pallet from the backward tilted position to its original horizontal position. However, there was a problem in that it was difficult to apply force when pulling the pallet diagonally upward, especially when the pallet was in a high position, resulting in poor workability.

[Purpose of the invention] The present invention improves the mechanism for holding the backward tilting position in order to facilitate the switching operation between the backward tilting position and the horizontal position of each pallet in a multi-stage pallet.

[Means for Achieving the Object] In order to achieve the above object, the multi-stage pallet of the present invention lifts the front edge of the pallet so that the pallet changes from a horizontal position to a backward tilted position. is pivotally supported on the frame, and a support rod is suspended from at least one side edge of the pallet so as to be able to swing back and forth, and the free end of the support rod has a hook-shaped rear edge cut out. A support shaft is provided inside the frame with which the engaging portion engages when the pallet is tilted backward at a predetermined angle, and the support rod supports the pallet by its own weight when the pallet is tilted backward at a predetermined angle or more. It is characterized in that the position of the engaging part suspended by the support shaft is provided at the rear of the support shaft.

[Example] An example of the present invention will be described with reference to the drawings. Supports 3a, 3b,
3c is established to construct a frame 3, and in the frame 3, a large number of rectangular plate-shaped pallets 4, 4, . . . are provided in multiple stages in the form of shelves. That is, each pallet 4 has a bearing sleeve 5 fixed to both sides of its rear edge, and a pivot 6 fixed to the rear strut 3a of the frame 3 is loosely fitted into the bearing sleeve 5, so that the pallet 4 can be attached to the frame 3. At the same time, a bracket 7 is fixed to the front end support 3c of the frame 3, and both sides of the front edge of the pallet 4 are supported by the bracket, so that the pallet 4 is held in a horizontal position. . A pin 8 is provided protruding from one side edge near the rear edge of the pallet 4, and a support rod 9 is suspended from the pin so that the support rod 9 can swing freely back and forth. This support rod is shaped like a plate of constant width, and an engaging portion 10 is formed at its free end by cutting the rear edge into a hook shape. 11 is the post 3 of the frame 3
This is a support shaft protruding from the inside of b. When the pallet 4 is tilted backward as shown in FIG. 4, the engaging portion 10 of the support rod 9 rests on the support shaft 11, so that the pallet 4 is maintained in the tilted position thereafter. Therefore, a wide working space is formed above the lower pallet. On the other hand, in order to release the backward tilting position of the pallet 4, the front edge of the pallet 4 is further lifted to make the backward tilt angle of the pallet even steeper.
As shown in the figure, the engagement portion 10 of the support rod 9 suspended by its own weight comes to be located behind the support shaft 11, and the engagement state is released. Therefore, when the front edge of the pallet 4 is lowered, the support shaft 11 comes into contact with the front surface of the support rod 9 as shown in FIG. 6, and the support rod 9 is rotated as shown by the arrow. Return to the state shown in Figure 2). Note that 12 indicates a stopper for preventing unnecessary swinging of the support rod 9 at this time.

[Effects of the invention] As described in the embodiments above, the multi-stage pallet of the present invention is such that when the pallet is tilted backward beyond a predetermined angle, the engaging portion of the support rod can overcome the support shaft, so that the engaged state is changed. Since the pallet is released and returned to a horizontal position, it can be easily operated by simply pushing up the front edge of the pallet that is tilted backwards, which reduces the burden on the worker and has a remarkable effect of improving work efficiency. .

Claims (1)

[Scope of utility model registration request] The rear edge of the pallet is pivoted to the frame so that the pallet changes from a horizontal position to a backward tilted position by lifting the front edge of the pallet, and a support rod is attached to at least one side edge of the pallet to swing back and forth. The pallet is hung so as to be movable, and the free end of the support rod is formed with an engaging part whose rear edge is cut into a hook shape, and the engaging part is formed inside the frame when the pallet is tilted backward at a predetermined angle. A support shaft with which the joint portion engages is provided, and the support rod is provided so that when the pallet is tilted backward by a predetermined angle or more, the position of the engaging portion suspended by its own weight is rearward of the support shaft.
