  However, the upper protrusions, for example, support the article when the pallet on which the article is placed is tilted, load and unload the article on the pallet, and carry the pallet. In the case of a collision, there is a concern that (plastic) deformation or damage will occur. In addition, due to deformation or breakage of the upper protrusion, it may be difficult to place the article on the deck portion or the article may easily fall from the deck portion.

  In addition, Patent Literature 1 discloses a technique for making the upper protrusion thick. However, when such a configuration is adopted, there is a concern that the upper protrusions may be deformed distorted due to a difference in molding shrinkage between the upper protrusions having different thicknesses and other parts.

  The present invention has been made to solve the above-described problems and the like, and its object is to suitably increase the strength of the upper protrusion and improve the durability in a nestable configuration. To provide a pallet.

  In the following, each means suitable for solving the above-mentioned purpose will be described in terms of items. In addition, the effect etc. peculiar to a corresponding means are added as needed.

Means 1. A flat deck portion on which articles can be placed;
A pallet comprising a plurality of leg portions projecting downward from the deck portion,
When the pallets are stacked one above the other, an accommodation recess for accommodating the legs of the pallets stacked on the upper side is provided,
On the upper surface side of the deck portion, the leg portion is formed on the lower surface side of the deck portion corresponding to the concave portion by forming a concave portion opening upward and recessed downward.
The housing recess is constituted by the recess,
An outer peripheral frame formed along the outer peripheral edge of the deck portion;
The outer peripheral frame is
An upper protrusion extending along the outer peripheral edge of the deck portion and protruding upward from the upper surface of the deck portion;
A lower protrusion extending along the outer peripheral edge of the deck portion and protruding downward from the lower surface of the deck portion;
An upper flange projecting from the upper end of the upper protrusion to the outer peripheral side of the deck part;
A lower flange protruding from the lower end of the lower protrusion to the outer peripheral side of the deck portion,
When the pallets are stacked one above the other so that the legs of the upper pallet are accommodated in the accommodating recesses of the lower pallet, the upper flange upper surface of the lower pallet and the upper pallet The pallet characterized by contacting the lower surface of the lower flange in the vertical direction.

  According to the means 1, by providing the upper flange that protrudes from the upper end portion of the upper protrusion to the outer peripheral side of the deck portion, it is possible to improve the strength of the upper protrusion. Therefore, for example, the pallet with the article placed thereon tilts and the article comes into pressure contact with the upper protrusion, or when the article is placed on the pallet, the article comes into contact with the outer peripheral frame (upper protrusion) When the fork is in contact with the outer peripheral frame (upper projection), deformation or breakage of the upper projection can be suppressed. As a result, it is possible to improve the durability of the outer peripheral frame, and thus the pallet, and it is difficult to place the article on the deck portion by plastic deformation of the upper protrusion (for example, tilting toward the inner peripheral side of the deck portion). It is possible to avoid such a situation that the article is easily dropped or the article is easily dropped from the deck portion due to breakage of the upper protrusion.

  Further, since the strength of the upper protrusion can be increased without making the upper protrusion thick, the upper protrusion becomes distorted when the pallet is formed due to the formation of the upper protrusion relatively thick. It is possible to avoid a situation such as deformation.

  In addition, when the pallets are stacked vertically (nested) so that the upper pallet legs are received in the lower pallet receiving recess, the upper pallet upper surface and the upper pallet It is comprised so that the lower flange lower surface of this pallet may contact | abut in an up-down direction. For this reason, when the pallet is nested, it is possible to prevent a situation in which it is difficult to release the nesting state because the leg portion of the upper pallet is fitted too deeply into the receiving recess of the lower pallet.

  Further, for example, there is no upper flange and lower flange, and the upper and lower pallet outer peripheral frames are compared with each other when the upper protrusion upper end of the lower pallet and the lower protrusion lower end of the upper pallet abut at the time of nesting. In addition, it is possible to increase the allowable range in which the contact state in the vertical direction between the outer peripheral frames can be maintained even if a slight positional deviation occurs between the upper and lower pallets in the inner and outer peripheral directions of the deck portion. . As a result, the nesting state is stabilized, and the upper protrusion of the lower pallet and the lower protrusion of the upper pallet come into contact with each other in the inner and outer peripheral directions of the deck portion during nesting (in the inner and outer peripheral directions of the deck portion). It is possible to avoid a situation in which the upper protrusion and the lower protrusion are deformed due to the occurrence of stress that presses each other.

  Mean 2. The outer peripheral frame includes a vertical rib extending linearly from the lower surface of the upper flange to the upper surface of the lower flange and connecting the upper flange and the lower flange. Pallet as described in.

  According to the means 2, the compressive strength in the vertical direction of the outer peripheral frame can be further increased. Therefore, it is possible to further enhance the function of the outer peripheral frame, such as preventing the article placed on the pallet from dropping or supporting the pallet stacked on the upper side during nesting. In addition, it is good also as "the said vertical rib is also connected with the said upper protrusion and the said lower protrusion." In this case, the strength of the outer peripheral frame can be further increased.

Means 3. The lower protrusion is arranged on the inner peripheral side of the deck portion with respect to the upper protrusion,
The pallet according to means 1 or 2, wherein the outer peripheral frame is formed so as to extend the lower protrusion downward, and is provided with a lower frame reinforcing rib protruding downward from the lower flange.

  According to the means 3, the strength of the lower flange can be increased and the deformation of the lower flange during nesting can be suppressed. Therefore, the nesting state can be further stabilized. In addition, it is good also as "the said downward protrusion and the said frame lowering rib are connected with the deck rib which protrudes below from the lower surface of the said deck part." In this case, the strength of the lower protrusion and the lower frame reinforcing rib can be increased, and consequently the strength of the lower flange and the like can be further increased.

  Also, for example, in the nesting state in which the pallets are stacked one above the other, when the upper pallet and the lower pallet are displaced in the horizontal direction, the lower frame reinforcing ribs of the upper pallet and the lower pallet Before the upper projection of the pallet comes into contact, the leg portion of the upper pallet and the inner surface of the receiving recess of the lower pallet come into contact with each other to prevent further displacement. It may be "being". In this case, the horizontal misalignment between the nested pallets can be controlled by bringing the upper pallet leg portion into contact with the inner surface of the lower pallet housing recess, and the lower frame reinforcing rib In addition, the (plastic) deformation or breakage of the upper protrusion can be more reliably prevented.

It is a perspective view which shows the upper surface side of a pallet. It is a perspective view which shows the lower surface side of a pallet. It is a perspective view of a pallet on which an article is placed. It is a perspective view containing the partial cross section of a pallet. It is a front view of the nesting pallet. FIG. 6 is a side view of a nested pallet. It is a partial expansion perspective view containing the partial cross section of the nested pallet.

  Hereinafter, an embodiment will be described with reference to the drawings. As shown in FIGS. 1 to 3, the pallet 1 has a substantially square shape (substantially square shape) in plan view, and has a flat plate shape on which an article 10 (a plurality of containers in the present embodiment; see FIG. 3) can be placed. A deck portion 2 and a plurality of leg portions 3 projecting downward from the deck portion 2 are provided. The leg portion 3 of the present embodiment is parallel to each of the outer leg portions 4 at a middle position between the pair of outer leg portions 4 and a pair of outer leg portions 4 extending along opposite side portions of the deck portion 2. In this way, the inner leg portion 5 extends. Furthermore, between each outer leg part 4 and the inner leg part 5, the fork insertion part 6 which can insert the fork of a handlift or a forklift is formed. Note that the pallet 1 of the present embodiment is integrally formed of polypropylene.

  Further, the leg portion 3 is formed on the lower surface side of the deck portion 2 corresponding to the concave portion by forming a concave portion that opens upward and is recessed downward on the upper surface side of the deck portion 2. Further, the leg 3 has a tapered shape that gradually decreases in diameter toward the lower side. As shown in FIGS. 5, 6, 7, and the like, when the pallets 1 are vertically stacked in the same direction, the legs 3 of the pallet 1 stacked on the upper side are connected to the lower pallet 1. It can be accommodated in the recess (hereinafter referred to as “accommodation recess 7”). In this way, by stacking (nesting) the pallets 1 so that the leg portions 3 are accommodated in the accommodating recesses 7, the height of the plurality of nested pallets 1 can be suppressed as much as possible.

  As shown in FIG. 2, on the lower surface side of the deck portion 2, deck ribs 8 that protrude downward from the lower surface of the deck portion 2 are provided. The deck ribs 8 are formed in a lattice shape in a range where the leg portions 3 are not formed. The deck ribs 8 also connect the outer leg portions 4 and the inner leg portions 5.

  Now, as shown in FIGS. 4, 7, etc., the pallet 1 of this embodiment includes an outer peripheral frame 11 formed along the outer peripheral edge of the deck portion 2. The outer peripheral frame 11 extends along the outer peripheral edge of the deck portion 2, extends upward from the upper surface of the deck portion 2, and extends along the outer peripheral edge of the deck portion 2. A lower projection 13 projecting downward from the lower surface, an upper flange 14 projecting from the upper side portion of the upper projection 12 to the outer peripheral side of the deck portion 2, and a lower flange projecting from the lower side portion of the lower projection 13 to the outer peripheral side of the deck portion 2 15.

  As shown in FIG. 7, when the pallet 1 is nested, the upper surface of the upper flange 14 of the lower pallet 1 and the lower surface of the lower flange 15 of the upper pallet 1 are in contact with each other in the vertical direction. ing. As a result, the upper pallet 1 is supported by the outer peripheral frame 11 of the lower pallet 1 at the outer peripheral frame 11, and the legs 3 of the upper pallet 1 are inserted into the receiving recesses 7 of the lower pallet 1. The amount will be specified. In the present embodiment, in the nesting state of the pallet 1, basically, the leg portion 3 of the upper pallet 1 and the inner surface of the receiving recess 7 of the lower pallet 1 do not come into pressure contact (a gap is formed in the horizontal direction). It is configured.

  In addition, as shown in FIGS. 4 and 7, support ribs 9 that are formed in the housing recess 7 and can support the lower surface of the leg portion 3 of the upper pallet 1 in the nesting state of the pallet 1 are provided. In this embodiment, when the pallet 1 is nested, the upper surface of the outer peripheral frame 11 (upper surface of the upper flange 14) of the lower pallet 1 and the lower surface of the outer peripheral frame 11 of the upper pallet 1 (lower surface of the lower flange 15) abut. At the same time, the upper side of the support rib 9 of the lower pallet 1 and the lower surface of the leg 3 of the upper pallet 1 are set in contact with each other. Accordingly, the support rib 9 can support the pallet 1 stacked on the upper side in cooperation with the outer peripheral frame 11, reduce the burden on the outer peripheral frame 11 in the nesting state, and the center of the pallet 1 stacked on the upper side. Prevention of deformation such that the part side bends downward is achieved.

  As shown in FIGS. 2 and 7, the outer peripheral frame 11 includes a lower frame reinforcing rib 17 that is formed so as to extend the lower protrusion 13 downward and protrudes downward from the lower flange 15. The lower protrusion 13 of the present embodiment is disposed on the inner peripheral side of the deck portion 2 with respect to the upper protrusion 12, and the deck portion 2 is more than the outer peripheral edge (the corresponding side portion of the deck portion 2) of the deck portion 2. It extends so as to be parallel to the side portion of the deck portion 2 at a position displaced to the inner peripheral side. Therefore, when the pallet 1 is nested, interference between the lower frame reinforcing rib 17 of the upper pallet 1 and the upper flange 14 of the lower pallet 1 can be avoided, and the lower surface of the lower flange 15 of the upper pallet 1 And the upper surface of the upper flange 14 of the lower pallet 1 can be reliably brought into contact with each other in the vertical direction.

  In the present embodiment, the upper protrusion 12 is also made to be parallel to the side portion of the deck portion 2 at a position slightly displaced to the inner peripheral side of the deck portion 2 from the corresponding side portion of the deck portion 2. It is extended. Further, the upper flange 14 and the lower flange 15 are configured such that their leading edges (outer edges) are located at the same position as the outer peripheral edge of the deck portion 2 in the inner and outer peripheral directions of the deck portion 2.

  Moreover, as shown in FIG. 1 etc., in this embodiment, the outer periphery frame 11 is formed in parts other than the part corresponding to the fork insertion part 6 among the deck parts 2. FIG. In addition, as shown in FIG. 7, the protruding length of the upper protrusion 12 from the upper surface of the deck portion 2 is longer than the protruding length of the lower frame reinforcing rib 17 from the lower protrusion 13 (lower surface of the lower flange 15). With these configurations, as shown in FIG. 5, when the pallet 1 is nested, the deck portion 2 of the lower pallet 1 above the portion where the outer peripheral frame 11 is not formed corresponding to the fork insertion portion 6. In this case, a gap is formed between the pallet 1 and the upper pallet 1. When the nesting state of the pallet 1 is released, it is possible to lift the upper pallet 1 by inserting a fingertip into the gap.

  Further, as shown in FIG. 2, the lower edge portion of the frame lower reinforcing rib 17 is configured to be at the same height as the lower edge portion of the deck rib 8. Further, the lower protrusion 13 and the lower frame reinforcing rib 17 are connected to the deck rib 8 extending orthogonally to the lower protrusion 13 and the lower frame reinforcing rib 17, and in particular, the lower protrusion of the present embodiment. 13 and the lower frame reinforcing rib 17 are configured to be connected to the leg portion 3 via the deck rib 8.

  Further, as shown in FIG. 7 and the like, the outer peripheral frame 11 extends linearly from the lower surface of the upper flange 14 to the upper surface of the lower flange 15 (appearing to penetrate the deck portion 2 up and down in the middle) A vertical rib 18 that connects the flange 14, the lower flange 15, the upper protrusion 12, and the lower protrusion 13, and a side rib 19 that protrudes from the side edge of the upper protrusion 12 to the outer peripheral side of the deck portion 2. It has. In the present embodiment, the vertical rib 18 extends vertically, while the side rib 19 extends diagonally corresponding to the fact that the side portion of the upper protrusion 12 extends diagonally. Yes. Further, the outer edges of the vertical ribs 18 and the side ribs 19 are also configured to be at the same position as the outer peripheral edge of the deck portion 2 in the inner and outer peripheral directions of the deck portion 2.

  Furthermore, as shown in FIG. 7, in this embodiment, in the nesting state of the pallet 1, the distance between the predetermined lower frame reinforcing rib 17 of the upper pallet 1 and the upper protrusion 12 of the lower pallet 1 is The leg 3 of the upper pallet 1 is configured to be longer than the distance between the surface on the predetermined frame lower reinforcement rib 17 side and the inner surface of the housing recess 7 of the lower pallet 1. Thereby, when the upper pallet 1 and the lower pallet 1 are displaced in the left-right direction in the nesting state of the pallet 1, the lower frame reinforcing ribs 17 of the upper pallet 1 and the lower pallet 1 Before the upper protrusion 12 comes into contact, the leg 3 of the upper pallet 1 and the inner surface of the receiving recess 7 of the lower pallet 1 come into contact with each other, thereby preventing further displacement.

  As described above in detail, according to the present embodiment, the upper flange 14 protruding from the upper end portion of the upper protrusion 12 to the outer peripheral side of the deck portion 2 is provided, thereby improving the strength of the upper protrusion 12 and the like. Can do. Therefore, for example, when the pallet 1 in a state where the article 10 is placed is inclined and the article 10 is pressed against the upper protrusion 12, or when the article 10 is placed on the pallet 1, the article 10 is moved to the outer peripheral frame 11 (upper protrusion 12. ), Or when the fork of the forklift comes in contact with the outer peripheral frame 11 (upper protrusion 12), the deformation or breakage of the upper protrusion 12 can be suppressed. As a result, it is possible to improve the durability of the outer peripheral frame 11 and by extension, the pallet 1, and the upper protrusion 12 is plastically deformed (for example, tilted toward the inner peripheral side of the deck portion 2), so that the article 10 is decked. It is possible to avoid such a situation that it is difficult to place the article 10 on the part 2 or the article 10 is easily dropped from the deck part 2 due to the upper protrusion 12 being damaged.

  Furthermore, since the strength of the upper protrusion 12 can be increased without increasing the thickness of the upper protrusion 12, the upper protrusion 12 is formed with a relatively thick wall. It is possible to avoid a situation in which the protrusion 12 is deformed to be distorted.

  Further, when the pallets 1 are stacked vertically (nested) so that the legs 3 of the upper pallet 1 are accommodated in the accommodating recesses 7 of the lower pallet 1, An upper surface of the upper flange 14 and a lower surface of the lower flange 15 of the upper pallet 1 are configured to contact each other in the vertical direction. For this reason, when the pallet 1 is nested, the leg portion 3 of the upper pallet 1 is too deeply fitted into the receiving recess 7 of the lower pallet 1 and it is difficult to release the nesting state (leg portion 3). Can be prevented from being removed from the housing recess 7).

  Further, for example, there is no upper flange 14 and lower flange 15 and the upper and lower ends of the upper projection 12 of the lower pallet 1 and the lower end of the lower projection 13 of the upper pallet 1 are in contact with each other when nesting. The contact area between the outer peripheral frames 11 of the pallet 1 is increased, and the contact state between the outer peripheral frames 11 in the vertical direction is increased even if a slight misalignment occurs between the upper and lower pallets 1 in the inner and outer peripheral directions of the deck portion 2. The allowable range that can be maintained can be increased. As a result, the nesting state is stabilized, and the upper protrusion 12 of the lower pallet 1 and the lower protrusion 13 of the upper pallet 1 come into contact with each other in the inner and outer circumferential directions of the deck portion 2 (deck portion). It is possible to avoid a situation in which the upper protrusion 12 and the lower protrusion 13 are deformed due to the occurrence of stress that presses each other in the inner and outer peripheral directions of the two.

  The outer peripheral frame 11 extends linearly from the lower surface of the upper flange 14 to the upper surface of the lower flange 15, and connects the upper flange 14, the lower flange 15, the upper protrusion 12, and the lower protrusion 13. Ribs 18 are provided. For this reason, the compressive strength in the up-down direction of the outer peripheral frame 11 can be further increased. Therefore, the function of the outer peripheral frame 11 such as preventing the article 10 placed on the pallet 1 from dropping or supporting the pallet 1 stacked on the upper side during nesting can be further enhanced.

  Further, the outer peripheral frame 11 includes a lower frame reinforcing rib 17 that is formed so as to extend the lower protrusion 13 downward and protrudes downward from the lower flange 15. For this reason, the strength of the lower flange 15 can be increased and deformation of the lower flange 15 during nesting can be suppressed. In particular, in the present embodiment, the lower protrusion 13 and the lower frame reinforcing rib 17 are connected to the deck rib 8 and further connected to the leg portion 3 through the deck rib 8. Thereby, the intensity | strength of the downward protrusion 13 and the frame lower reinforcement rib 17 can be raised, and by extension, the intensity | strength of the lower flange 15 grade | etc., Can be raised further. In addition, the strength of the portion of the deck portion 2 that supports the outer peripheral frame 11 can be effectively increased by the deck rib 8 connecting the lower protrusion 13 and the frame lower reinforcing rib 17 and the leg portion 3. Therefore, it is possible to reliably prevent a situation in which the outer peripheral frame 11 is tilted as a whole due to deformation or breakage of the base portion of the outer peripheral frame 11. As a result, the nesting state can be further stabilized.

  In the present embodiment, when the upper pallet 1 and the lower pallet 1 are displaced in the left-right direction in the nesting state of the pallet 1, the lower frame reinforcing ribs 17 of the upper pallet 1 and the lower pallet 1 Before the upper projection 12 of the pallet 1 comes into contact, the leg 3 of the upper pallet 1 and the inner surface of the receiving recess 7 of the lower pallet 1 come into contact with each other, so that further displacement is prevented. It is configured. Therefore, the horizontal displacement between the nested pallets 1 can be regulated by bringing the legs 3 of the upper pallet 1 into contact with the receiving recesses 7 of the lower pallet 1. It is possible to prevent (plastic) deformation or breakage of the lower reinforcing rib 17 and the upper protrusion 12.

  In addition, it is not limited to the description content of the said embodiment, For example, you may implement as follows. Of course, other application examples and modification examples not illustrated below are also possible.

  (A) In the said embodiment, the shape, arrangement | positioning, etc. of the leg part 3 are not specifically limited, A design change is possible suitably for every pallet. For example, in the above embodiment, the pallet 1 is embodied in the two-way insertion type pallet 1 in which the fork can be inserted from two side surfaces among the four side surfaces constituting the outer peripheral surface of the pallet 1. Four-way difference comprising four corner legs, an intermediate leg provided at an intermediate portion of a pair of corner legs arranged along the side of the pallet 1, and a center leg provided at the center of the pallet 1 It is also possible to embody a type of pallet.

  (B) In the above-described embodiment, the outer peripheral frame 11 is not formed at the portion corresponding to the fork insertion portion 6 in the outer peripheral edge of the deck portion 2, but the formation position and the like of the outer peripheral frame 11 are particularly limited. It is good also as forming over the perimeter of the outer periphery of the deck part 2, for example.

  In the above embodiment, the underframe reinforcing rib 17 may be omitted. In this case, even if the position of the upper protrusion 12 and the position of the lower protrusion 13 in the inner and outer peripheral directions of the deck portion 2 are not shifted, the upper flange 14 of the lower pallet 1 and the lower pallet 1 The flange 15 can be brought into contact.

  Further, in the above embodiment, the vertical rib 18 is omitted, the rib connecting the lower surface of the upper flange 14 and the upper surface of the deck portion 2, and the upper surface of the lower flange 15 and the lower surface of the deck portion 2 are connected. It is also possible to provide the ribs at different positions. However, by providing the vertical ribs 18 as in the above-described embodiment, the compressive strength in the vertical direction of the outer peripheral frame 11 can be effectively increased (suppressing an increase in the number of ribs) and dramatically increased.

  (C) In the above embodiment, the protruding lengths of the upper protrusion 12, the lower protrusion 13, and the lower frame reinforcing rib 17 are not particularly limited, but the lower frame reinforcing rib 17 is more than the deck rib 8 from the viewpoint of preventing damage. In addition, it is desirable that the protrusion does not protrude downward, and from the viewpoint of preventing the article 10 from falling, it is desirable to secure the protrusion length of the upper protrusion 12 as much as possible (for example, to make it longer than the protrusion length of the lower protrusion 13).

  (D) In the above embodiment, when the pallet 1 is nested, the upper surface of the upper flange 14 of the lower pallet 1 is in contact with the lower surface of the lower flange 15 of the upper pallet 1 and supports the lower pallet 1. The upper side of the rib 9 and the lower surface of the leg 3 of the upper pallet 1 are set to contact each other. For example, the upper side of the support rib 9 of the lower pallet 1 and the leg 3 of the upper pallet 1 are set. It may be configured such that a slight gap (for example, about 1 mm) is formed between the lower surface and the upper pallet 1 in contact with the slightly bent space. The support rib 9 can be omitted.

  (E) In the above embodiment, the pallet 1 is made of polypropylene, but may be made of other resin materials such as polyethylene, PET, and polyamide.
