[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a synthetic resin pallet on which various articles are placed for transportation or storage.
[0002]
[Prior art]
2. Description of the Related Art Conventionally, a synthetic resin pallet having a fork insertion hole into which a fork of a known hand forklift having a front wheel that can be moved up and down by a jack at the tip end can be inserted is known.
[0003]
[Problems to be solved by the invention]
As shown in FIG. 4 which is a vertical sectional view along the depth direction of the fork insertion hole 1 of the conventional synthetic resin pallet, the bottom 2 and the fork insertion hole 1 constituting the inlet portion of the fork insertion hole 1 The upper surface of the bottom portion 3 of the central portion is formed in a mountain shape including central portions 2a and 3a formed in a horizontal plane and inclined portions 2b and 3b inclined downward from both end portions of the central portions 2a and 3a. . Since the top surfaces of the mountain-shaped bottom portions 2 and 3 are formed to be smooth surfaces without irregularities or the like, it becomes difficult for the front wheels of the hand forklift to get over the bottom portions 2 and 3. There is a problem that the hand forklift must be inserted into the fork insertion hole 1 or pulled out from the fork insertion hole 1 by pushing or pulling the hand forklift.
[0004]
In recent years, synthetic resin pallets have been integrally molded by injection molding and have a rib structure to reduce the weight of synthetic resin pallets. When a hand forklift is inserted into the insertion hole 1 or when a hand forklift is pulled out of the fork insertion hole 1, the hand forklift is pushed or pulled so that the front wheel of the hand forklift gets over the bottoms 2 and 3 There is a problem that the synthetic resin pallet moves and the hand forklift cannot be put in and out quickly.
[0005]
In order to solve the problems as described above, it is conceivable to make the slopes 2b and 3b of the bottom parts 2 and 3 gentle. However, if the slopes 2b and 3b are made gentle, the bottom parts 2 and 3 A problem arises that the back deck board including the thickness becomes thin and the strength of the back deck board decreases.
[0006]
The objective of this invention is providing the synthetic resin pallet which improved the workability while solving the subject which the conventional synthetic resin pallet mentioned above has.
[0007]
[Means for Solving the Problems]
In order to achieve the above-mentioned object, the present invention is a synthetic resin pallet having a bottom portion of a fork insertion hole comprising a central portion and inclined portions inclined downward from both end portions of the central portion, the bottom portion constituting the bottom portion The inclined portion is formed in a rib structure in which a front rib extending in the front direction of the fork insertion hole and a depth rib extending in the depth direction of the fork insertion hole intersect in a lattice shape, and the central portion A gap is formed between the central portion and the inclined portion disposed between the center portion, and the front fork lift ribs on which the wheels of the hand forklift mounted on the inclined portion constituting the bottom portion intersect in a lattice shape and It is configured to be placed on the depth direction rib.
[0008]
【Example】
1 is an overall perspective view of the synthetic resin pallet of the present invention, FIG. 2 is a perspective view of the vicinity of the fork insertion hole of the synthetic resin pallet of the present invention, and only the bottom of the synthetic resin pallet of the present invention. An embodiment of the present invention will be described with reference to FIG. 3 which is a perspective view including a cross section. However, the present invention is not limited to this embodiment unless it exceeds the gist of the present invention. In the synthetic resin pallet of the present invention, the same reference numerals are used for the same components as the conventional synthetic resin pallet shown in FIG.
[0009]
In the present invention, the conventional inclined portions 2b and 3b that form the bottom portion 2 of the inlet portion of the fork insertion hole 1 and the bottom portion 3 of the center portion of the fork insertion hole 1 have a rib structure as will be described later. In addition, since the bottom part 2 of the inlet part of the fork insertion hole 1 and the bottom part 3 of the center part of the fork insertion hole 1 have substantially the same structure, the inlet part of the fork insertion hole 1 will be described below. The structure of the bottom part 2 will be described.
[0010]
The bottom portion 2 of the inlet portion of the fork insertion hole 1 is formed between an inclined portion 5 located on the inlet side of the fork insertion hole 1, an inclined portion 6 located on the back side of the fork insertion hole 1, and both inclined portions 5, 6. It is comprised from the center part 7 located. The inclined portion 5 located on the inlet side of the fork insertion hole 1 has a structure formed by intersecting the ribs 5a in a lattice shape. In this embodiment, the inclined portion 5 extends toward the front edge of the fork insertion hole 1. The front edge rib 5a and the depth rib 5a extending in the depth direction. Similarly, the inclined portion 6 located on the back side of the fork insertion hole 1 also has a structure formed by intersecting the ribs 6a in a lattice shape, and the front direction extending in the front direction of the fork insertion hole 1 It is comprised by the rib 6a and the depth direction rib 6a extended in a depth direction.
[0011]
The central portion 7 constituting the bottom portion 2 of the fork insertion hole 1 has a plate-like horizontal portion 7a and a reinforcing rib 7b suspended from the lower surface of the horizontal portion 7a. The small hole 7c which can permeate | transmit is drilled.
[0012]
As described above, the inclined portion 5 located on the inlet side of the fork insertion hole 1 and the inclined portion 6 located on the back side of the fork insertion hole 1 are configured such that the ribs 5a and 6a intersect in a lattice pattern. Thus, when the hand forklift is pulled out from the fork insertion hole 1, the front wheel of the hand forklift is caught by the ribs 5a and 6a and does not slide like the conventional plate-like inclined surface 2b. Therefore, it is easy to get over the inclined portion 5 located on the inlet side of the fork insertion hole 1 and the inclined portion 6 located on the back side of the fork insertion hole 1.
[0013]
When the hand forklift is pulled out from the fork insertion hole 1, the front wheel of the hand forklift is caught on the ribs 5a, 6a. However, the forklift can be put in and out quickly without the synthetic resin pallet moving.
[0014]
Furthermore, since the inclined portions 5 and 6 of the bottom portions 2 and 3 have a rib structure and the central portion 7 is formed in a plate shape, excessive weight reduction of the synthetic resin pallet can be prevented, so a hand forklift can be inserted, Alternatively, the movement of the synthetic resin pallet due to weight reduction when being pulled out can be prevented.
[0015]
In the embodiment, there is shown an example in which a gap is formed between the central portion 7 and the inclined portions 5 and 6 arranged with the central portion 7 interposed therebetween. The portion 7 and the inclined portions 5 and 6 can be connected, and the horizontal portion 7a of the central portion 7 extends to the ribs 5a and 6a of the inclined portions 5 and 6 on the central portion 7 side, so that The part 7 and the inclined parts 5 and 6 can also be connected.
[0016]
【The invention's effect】
Since the present invention is configured as described above, the following effects can be obtained.
[0017]
When the front wheel of the hand forklift climbs over the bottom, the resistance of the front wheel of the hand forklift increases, and the front wheel of the handforklift can easily get over the inclined part without slipping, and it is pushed by the hand forklift and made of synthetic resin The pallet never moves.
