Description

[Detailed description of the invention] (Industrial application field) The mesh pallet is provided with a door surface that can be opened and closed to facilitate the loading and unloading of conveyed cargo.

The present invention relates to a mounting device for the door surface, and is characterized by achieving the purpose of reliably latching the door surface in the closed state and providing remarkable robustness of the latching portion. It is something.

(Prior art) As a conventional device of this type,
There is one shown in Publication No. 27729. As shown in Fig. 4, this is configured to stabilize the door in the closed state by hooking both ends of the frame of the door to a hook-shaped metal fitting A whose upper end is an open end. It is something.

(Problems to be solved by the invention) With the conventional device as described above, a force is applied to the hook-shaped fitting A to draw it forward, such as by strongly pulling the door surface in the closed state forward. When working, the upper open end of the metal fitting A expands, and if such deformation occurs, the door surface that is in the latched state may rattle, or in extreme cases, the door surface may become unlatched. This has inevitably led to problems such as discrepancies between the two.

This proposal is characterized by its attempt to solve the problems in the prior art as described above.

(Means for solving the problem) This proposal is based on an upper frame having both ends as lateral protrusions on the upper edge of the door surface 2 to be attached to the upper front half of the net basket pallet 1 so as to be openable and closable. At the same time, a pivot 2a is fixed to the lower edge of the door surface 2, and both ends of the pivot 2a are symmetrically attached to the pillars 1a, 1a on the door surface attachment side of the net basket pallet 1. The latching rods 4, 4 are supported on the pivot fittings 3, 3 exhibiting an octopus shape so as to be able to rise and fall and rotate freely, and further have a restraining rod portion 4a exhibiting an outwardly inclined shape formed in a U shape. The above-mentioned pillars 1a, 1a are fixed near the upper ends, and the fixed positions of the latching rods 4, 4 are as follows:
The upper end of the oblique restraining rod portion 4a is located outside the protruding end of the upper frame 2b of the door surface 2, and
The lower end of the restraining rod 4a is located inside the protruding end of the frame 2b, and furthermore, when the door surface 2 is pulled upward, both ends of the upper frame 2b are positioned above the restraining rod 4a. This invention relates to a door surface mounting device for a net basket pallet, which is characterized in that it is configured to be fixedly installed in such a state.

(Operation) To open the door surface 2 which is in the closed state as shown in FIGS. 1 and 2, the door surface 2 is pulled upward. This is because the door surface 2 is supported at both ends of its pivot 2a by the U-shaped pivot fittings 3, 3 so as to be able to move up and down and rotate freely. It will be raised within the range of .

Both ends of the upper frame 2b of the door surface 2 pulled up as described above are positioned above the oblique restraining rod portions 4a of the latching rods 4, 4, and the latching is released. That will happen. Therefore, the door can be opened by tilting the door surface 2 forward.

In addition, when closing the door surface 2, both ends of the upper frame 2b are connected to the restraining rod portions 4 based on the above-mentioned reverse operation.
Just hang it on a again.

(Example) An example of the configuration of the present proposal shown in the drawings will be described in detail as follows.

In the figure, 1 is a net basket pallet, and an upper frame 2b having side projecting portions at both ends is fixed to the upper edge of a door surface 2 to be attached to the upper half of the front face so as to be openable and closable. Further, a pivot 2a is fixedly attached to the lower edge thereof.

Reference numerals 3 and 3 refer to U-shaped pivot fittings that are symmetrically attached to the pillars 1a, 1a on the door surface attachment side of the net basket pallet 1, and support both ends of the pivot shaft 2a so as to be able to rise and fall and rotate freely. ing.

4 and 4 are formed into a U-shape by providing upstanding rod portions 4b and 4c at both ends of a restraining rod portion 4a exhibiting an outwardly inclined shape for restraining the protruding portions at both ends of the upper frame 2b of the door surface 2. Attachment rod portions 4d and 4e, which are latching rods, are connected to the ends of the rising rod portions 4b and 4c, respectively, and are fixed to the pillars 1a and 1a. In addition, the support 1 of the latching rod portions 4, 4
a, 1a, the upper end of the oblique restraint rod 4a is located outside the protruding end of the upper frame 2b of the door surface 2, and the upper end of the restraint rod 4a is The lower end is located inside the protruding end of the frame 2b, and is further fixed in such a manner that both ends of the upper frame 2b are located above the restraining rod portion 4a when the door surface 2 is pulled upward. It has been done.

(Effects of the invention) In the present proposal, the locking rods 4, 4 each having an outwardly inclined restraining rod portion 4a formed in a tunnel shape are fixed near the upper ends of the pillars 1a, 1a, and
The locking rods 4, 4 are fixed so that the upper end of the oblique restraining rod portion 4a is located outside the protruding end of the upper frame 2b of the door surface 2, and the retaining rod portion 4a is
The lower end of the upper frame 2b is located inside the protruding end of the frame 2b, and the upper frame 2b is fixed in such a manner that both ends of the upper frame 2b are located above the restraining rod 4a when the door surface 2 is pulled upward. The gist of the present invention is a device for attaching a door surface of a net basket pallet, which is characterized in that the device is configured to attach the net basket pallet to the door surface.

Since this proposal adopts the above-mentioned configuration, when the door surface 2 is held in the closed state, the protruding end of the upper frame 2b on the door surface 2 has both upper and lower ends fixed to the pillar. Even if the restraint rod part 4a has a U-shaped configuration, the door surface relative to the protruding end of the upper frame 2b is Engagement and disengagement for opening and closing will be easily permitted.

Therefore, the present proposal completely eliminates the above-mentioned problems such as the tendency for the upper open end to expand in the conventional hook-shaped metal fitting A as shown in Fig. 4. However, if the hook-shaped metal fitting A has a protruding end, there is a risk of clothes etc. getting caught, but this proposal eliminates such concerns.

Since the present invention has a simple structure and excellent practical effects as described above, its utility value is extremely high as a device for attaching the door surface of a net basket pallet.
