Disclosed.

Utility Model Publication No. 6-61728

In the mounting structure disclosed in Patent Document 1, in the work of fitting the anti-slip member into the pallet, there is a risk that the anti-slip member may be placed in an inclined state in the insertion hole of the anti-slip member provided on the pallet side. If the anti-slip member is arranged in an inclined state and is inserted into the insertion hole as it is, there is a risk that the insertion hole will be damaged.

The present invention has been made in view of the above-mentioned problems, and an object of the present invention is to suppress damage to a hole into which an anti-slip member is inserted.

A carrying tool according to aspect 1 of the present invention is a carrying tool comprising an anti-slip member and a main body into which the anti-slip member is fitted, wherein the anti-slip member is fitted into the main body. When the anti-slip member is inserted into the main body, it has a contact surface that comes into contact with the main body, and is located on the outer side of the center region of the contact surface and below, which is the fitting direction in which the anti-slip member is inserted into the main body from the contact surface. a locking part extending in the direction and locking the non-slip member to the main body when the non-slip member is fitted into the main body; a positioning convex portion extending longer than the length of the locking portion in the downward direction; A stop part, a positioning recess into which the positioning convex part is fitted, and a partition wall that partitions the locked part and the positioning recess between the locked part and the positioning recess. .

In the above configuration, the anti-slip member includes the locking portion and the positioning convex portion extending downward, which is the insertion direction in which the anti-slip member is fitted, longer than the length of the locking portion in the downward direction. Further, the main body portion includes a locked portion and a positioning recess. As a result, in the work of fitting the anti-slip member into the main body, the positioning protrusion, which is longer than the locking part, is first fitted into the positioning recess, and then the locking part is fitted into the locked part. It turns out. In addition, since the positioning convex portion extends downward from the central area of the contact surface that abuts the main body, it is possible to adjust the fitting angle at the center position between the positioning convex portion and the positioning concave portion, that is, to prevent slippage. It is possible to suppress the stop member from falling sideways. Therefore, the fitting angle of the non-slip member relative to the main body is stabilized, and by stabilizing the posture of the non-slip member, it is possible to prevent the non-slip member from being inserted diagonally. Damage can be suppressed.

For example, if the positioning protrusions are provided at both ends instead of in the central area, the angle of the rotation direction of the anti-slip member in plan view can be adjusted by aligning the positioning protrusions at both ends with the corresponding positioning recesses. The need arises. On the other hand, according to the above configuration, it is only necessary to adjust the angle of the rotation direction of the anti-slip member in plan view only at the central position, compared to a structure in which the positioning convex portion is provided not at the central area but at both ends. The anti-slip member can be easily aligned with the main body. Therefore, the work of inserting the anti-slip member can be carried out smoothly.

The carrier also includes a partition wall between the locked part and the positioning recess, which partitions the locked part and the positioning recess. Thereby, the hole in the main body into which the anti-slip member is inserted can be in a state where the partition wall is installed. Therefore, for example, since the strength of the hole can be increased compared to a hole in which the locked portion and the positioning recess are in communication, damage to the hole into which the anti-slip member is fitted can be suppressed.

In the carrier according to aspect 2 of the present invention, in the above-mentioned aspect 1, the positioning convex portion is a first positioning convex portion provided extending in a first direction that is a predetermined direction along the contact surface. , a second positioning convex portion extending from a central position of the first positioning convex portion in a second direction orthogonal to the first direction, and the positioning concave portion is provided on the contact surface of the main body portion. a first positioning recess extending in the first direction and a second positioning convex extending from the center of the first positioning recess in the second direction orthogonal to the first direction; A second positioning recess formed along the shape may be provided.

According to the above configuration, the positioning protrusion includes the first positioning protrusion and the second positioning protrusion. Further, the positioning recess includes a first positioning recess corresponding to the first positioning projection and a second positioning recess corresponding to the second positioning projection. Moreover, the second positioning recess is formed along the shape of the second positioning protrusion. Thereby, when the first positioning convex portion is fitted into the first positioning concave portion, the second positioning convex portion is positioned in the second positioning concave portion at the center position of the first positioning concave portion. That is, when fitting the anti-slip member into the main body, the locking portion and the locked portion can be easily aligned, and the anti-slip member can be fitted into the main body in a stable posture. Therefore, damage to the hole into which the anti-slip member is inserted can be suppressed.

In the carrier according to aspect 3 of the present invention, in the above aspect 2, the first positioning recess is formed such that the width in the second direction increases from the outside toward the center position in the first direction. The length of the second positioning recess in the second direction may be shorter than the length of the first positioning recess in the first direction.

According to the above configuration, the first positioning recess is formed so that the width in the second direction increases from the outside toward the center position in the first direction. Further, the length of the second positioning recess in the second direction is shorter than the length of the first positioning recess in the first direction. This makes it easier to guide the second positioning convex portion to the center position of the first positioning concave portion while aligning the second positioning convex portion with the first positioning concave portion during the work of fitting the anti-slip member into the main body portion. Therefore, the anti-slip member can be easily positioned on the main body.

In the carrier according to aspect 4 of the present invention, in any one of aspects 1 to 3 above, the locking portion is a locking portion extending downward from the contact surface of the anti-slip member. The locking piece has a locking protrusion that projects laterally from the locking piece, and the locking protrusion has a cross-sectional shape in a plan view formed by a curve having an apex in the protruding direction. It is also possible to have a configuration including an inclined surface that slopes downward.

According to the above configuration, the locking part has a locking piece and a locking protrusion, and the locking protrusion has a cross-sectional shape in a plan view of a curve having an apex in the protruding direction, and the locking protrusion has a cross-sectional shape in a plan view that extends downward. It has an inclined surface that slopes toward the target. As a result, when the anti-slip member is placed on the main body, the inclined surface of the locking convex portion and the locked portion come into contact with each other, creating a temporarily fitted state in which the posture of the anti-slip member is stabilized. By creating a temporarily fitted state of the anti-slip member, it is possible to suppress the anti-slip member from falling sideways. Further, since the locking convex portion is formed in a curved line having an apex in the protruding direction, the amount of engagement with the locked portion increases, and the attachment strength can be improved.

In the carrier according to aspect 5 of the present invention, in any one of aspects 1 to 4 above, the locking parts are arranged at positions facing each other across the positioning convex part, and the locked part is a curved line whose cross-sectional shape in plan view has an apex in the direction from the positioning recess toward the locked portion at a position facing the locking portion when the anti-slip member is placed on the main body portion; It is also possible to have a configuration including an inclined receiving part formed of and inclined downward.

According to the above configuration, when the anti-slip member is placed on the main body, the locked portion is located at a position opposite to the locking portion, and the cross-sectional shape in plan view is directed from the positioning recess toward the locked portion. The anti-slip member includes an inclined receiving portion that is formed in a curved line having an apex in the direction and inclined downwardly of the anti-slip member. Thereby, when the anti-slip member is placed on the main body portion, the locking portion and the inclined receiving portion of the locked portion come into contact with each other. In addition, since the inclined receiving part is formed with a curved line having an apex in the direction from the positioning recess to the locked part, the contact surface between the locking part and the inclined receiving part increases, so the posture of the anti-slip member can be adjusted. It is possible to create a temporary fit state that stabilizes the structure. By creating a temporarily fitted state of the anti-slip member, it is possible to suppress the sliding member from falling sideways.

In the carrier according to aspect 6 of the present invention, in any one of aspects 1 to 5 above, the anti-slip member includes a side wall extending upward from a side of the contact surface, and the main body portion is , a recess-shaped non-slip accommodating portion formed by an accommodating wall provided along the outer circumferential surface of the side wall and a bottom surface provided at a position facing the abutment surface, the side wall of the non-slip member being , a second housing that abuts the upper end of the first housing wall located at the upper end of the first housing wall that is one of the housing walls, and that a lower end surface of the positioning convex portion faces the first housing wall; The shapes of the non-slip member and the non-slip accommodating portion are set so that the non-slip member and the non-slip accommodating portion can be placed in an inclined state in contact with the upper end of the second accommodating wall located at the upper end of the wall. It may be configured such that when the device is placed in an inclined state, the angle between the contact surface and the bottom surface is 30° or more.

According to the above configuration, the anti-slip member includes the side wall. Further, the main body portion includes a recess-shaped non-slip accommodating portion formed by an accommodating wall provided along the outer circumferential surface of the side wall and a bottom surface.

Furthermore, when the non-slip member is placed in the non-slip housing, the side wall of the non-slip member comes into contact with the top end of the first storage wall, and the surface of the bottom end of the positioning protrusion comes into contact with the top end of the second storage wall. Then, the shape of the non-slip accommodating portion is set so that the device is placed in an inclined state. Further, when the anti-slip member is placed in an inclined state, the angle between the contact surface and the bottom surface becomes 30 degrees or more.

As a result, in the operation of fitting the positioning protrusion into the positioning recess, the anti-slip member cannot take a stable posture unless the positioning protrusion is fitted into the positioning recess. That is, it can be easily confirmed from the appearance that the angle is such that the anti-slip member cannot be inserted. Therefore, it becomes easy to determine whether the anti-slip member can be fitted into the carrier without any problem, and it is possible to suppress damage to the hole into which the anti-slip member is inserted.

A carrying tool according to aspect 7 of the present invention is provided in any one of aspects 1 to 6 above, wherein the anti-slip member is provided on a base formed of a first material and on the upper surface of the base, and the anti-slip member is provided on the upper surface of the base. an anti-slip layer formed from a second material having higher flexibility than the first material, and an adhesive surface for adhering the base and the anti-slip layer between the base and the anti-slip layer. In addition, the adhesive surface may include an adhesive surface in a region between the locking portion and the positioning convex portion, at least a portion of which is recessed toward the contact surface from other adhesive surfaces. Good too.

According to the above configuration, the anti-slip member includes the base and the anti-slip layer having higher flexibility than the base. Further, an adhesive surface is provided between the base and the anti-slip layer. Furthermore, the adhesive surface is provided with an adhesive surface that is recessed toward the contact surface from the other adhesive surfaces in a region between the locking portion and the positioning convex portion.

As a result, more anti-slip layers are provided on the recessed adhesive surface than on other adhesive surfaces. That is, a region having a depressed adhesive surface is more easily deformed than other adhesive surfaces. Therefore, it becomes easier to fit the locking part into the locked part.

Furthermore, since the anti-slip layer, which is more flexible than the base, is formed above the base, the anti-slip effect is more easily exhibited.

According to the present invention, it is possible to suppress damage to the hole into which the anti-slip member is inserted.

Embodiments of the present invention will be described in detail below. FIG. 1 is a perspective view showing a pallet 1, which is an example of a carrier according to the present invention.

<Overview of Palette 1>
As shown in FIG. 1, the pallet 1 includes a non-slip member 10 and a main body portion 2 into which the non-slip member 10 is fitted. The pallet 1 has a substantially rectangular shape in plan view, and is made of resin made of polyolefin, for example.

The main body portion 2 has main planes F on the upper and lower surfaces when it is placed horizontally. The main plane F is used, for example, as a loading surface for cargo or a loading surface when pallets 1 are stacked on top of each other. The main body portion 2 is provided with a pair of fork insertion holes 2a on its side surface. Note that the number of fork insertion holes 2a is not limited to one pair, and may be provided on all sides of the pallet 1.

Anti-slip members 10 are provided near each side of the main plane F of the main body portion 2 . In the main body 2 of the pallet 1 shown in FIG. 1, a total of 16 anti-slip members 10 can be placed near each side, but the number and placement locations of the anti-slip members 10 are not limited to this. However, the number and location may be changed as appropriate.

<Non-slip member 10>
Next, details of the anti-slip member 10 will be explained. FIG. 2 is a diagram showing the anti-slip member 10 fitted into the main body portion 2 of the pallet 1, which is an example of the carrier according to the present invention. A21 in FIG. 2 is a perspective view of the anti-slip member 10 when viewed from above, A22 is an enlarged view of the portion indicated by the broken line P in FIG. 1, A23 is a perspective view of the anti-slip member 10 when viewed from the bottom, and A24 is a front view of A21.

As shown at A21 and A23 in FIG. 2, the anti-slip member 10 includes an anti-slip surface 11, a contact surface 12, a side wall 13, a side wall recess 14, a locking portion 20, and a positioning convex portion 30. The anti-slip member 10 has a substantially rectangular shape in plan view, and is made of resin such as elastomer, for example.

(Non-slip surface 11)
The anti-slip surface 11 is formed so as to protrude slightly above the main plane F when the anti-slip member 10 is fitted into the main body 2, as shown at A22 in FIG. As a result, the anti-slip surface 11 suppresses the cargo placed on the main plane F or the pallets 1 stacked thereon from shifting in the horizontal direction.

(Abutment surface 12)
The contact surface 12 is a surface that faces the main plane F when the anti-slip member 10 is fitted into the main body portion 2 . It is also a surface that comes into contact with the main body 2 when the anti-slip member 10 is fitted into the main body 2. When the anti-slip member 10 is fitted into the main body 2 and the main body 2 and the abutting surface 12 come into contact with each other, the abutting surface 12 is arranged downward to prevent the anti-slip member 10 from moving in the insertion direction (downward). Regulate movement to.

(Side wall 13)
The side walls 13 are walls that extend upward from each side of the contact surface 12 . The side wall 13 is provided so as to correspond to a housing wall of a non-slip housing section 40 which will be described later, so when the non-slip member 10 is fitted into the main body 2, the side wall 13 and the housing wall come into contact with each other or The anti-slip member 10 approaches the main plane F and restricts movement of the anti-slip member 10 in the horizontal direction.

(Side wall recess 14)
The side wall recess 14 is provided in the longitudinal direction of the side wall 13 of the anti-slip member 10. The side wall recess 14 is formed by recessing the central region of the side wall 13 in the longitudinal direction inward. When the anti-slip member 10 is fitted into the main body 2, the side wall recess 14 forms a water guide hole H by the anti-slip accommodating portion 40 and the side wall recess 14, which will be described later. A more detailed explanation will be given later.

(Locking part 20)
As shown at A21 and A23 in FIG. 2, two locking portions 20 are provided outside the central region of the contact surface 12. Specifically, the locking parts 20 are arranged at positions facing each other with a positioning convex part 30, which will be described later, in between. The locking portion 20 extends downward from the contact surface 12, which is the insertion direction in which the anti-slip member 10 is inserted into the main body portion 2, and when the anti-slip member 10 is inserted into the main body portion 2, the anti-slip member 10 is inserted into the main body portion 2. The anti-slip member 10 is locked to the portion 2.

The locking portion 20 includes a locking piece 21 extending downward from the contact surface 12 of the anti-slip member 10 . The locking piece 21 has a locking protrusion 22 that projects laterally from the locking piece 21 . As shown in FIG. 2, the locking convex portion 22 is provided so as to protrude in the opposite direction (outside) from the positioning convex portion 30 with the locking piece 21 in between. The locking convex portion 22 has a cross-sectional shape in a plan view formed by a curved line (for example, an arc shape) having an apex in the protrusion direction, and includes an inclined surface 23 that slopes downward. Although it has been explained here that the locking protrusion 22 is provided so as to protrude in the opposite direction (outside) from the positioning protrusion 30 with the locking piece 21 in between, the locking protrusion 22 may protrude. The direction is not limited to this. For example, the locking projection 22 may have a shape that projects from the locking piece 21 toward the positioning projection 30 (inside).

Furthermore, the locking portion 20 includes reinforcing ribs 24, as shown at A21 and A23 in FIG. The reinforcing rib 24 is provided in the locking portion 20 in a direction opposite to the direction in which the locking convex portion 22 protrudes, and extends downward from the contact surface 12 along the locking piece 21 . Thereby, the reinforcing rib 24 suppresses damage to the locking piece 21.

(Positioning protrusion 30)
As shown at A21 in FIG. 2, the positioning convex portion 30 extends downward from the central region of the contact surface 12 to be longer than the length of the locking portion 20 in the downward direction. More specifically, as shown at A24 in FIG. The positioning protrusion 30 is provided so that the length T2, which is the length from the positioning protrusion 30 to the lower end of the positioning protrusion 30, is longer.

Moreover, the positioning convex part 30 is provided with the 1st positioning convex part 31 and the 2nd positioning convex part 32, as shown in A21 and A23 of FIG. The first positioning convex portion 31 is provided extending in a first direction that is a predetermined direction along the contact surface 12 . The first direction, which is a predetermined direction, is, for example, the lateral direction of the anti-slip member 10 shown at A21 and A23 in FIG.

The second positioning protrusion 32 is provided extending from the center of the first positioning protrusion 31 in a second direction orthogonal to the first direction. In other words, the positioning convex portion 30 is formed into a cross shape when viewed from the bottom (the side indicated by A23 in FIG. 2) by the first positioning convex portion 31 and the second positioning convex portion 32. Note that although the first direction is described here as the lateral direction, the lateral direction may be the second direction.

In this way, the positioning convex portion 30 extends downward from the central region of the contact surface 12 that contacts the main body portion 2 . Therefore, when the positioning protrusion 30 is fitted into the positioning recess 60, the fitting angle at the center position between the positioning protrusion 30 and the positioning recess 60 can be adjusted. In other words, it is possible to suppress the anti-slip member 10 from falling sideways. In addition, it is only necessary to adjust the angle of the rotation direction of the anti-slip member 10 in plan view only at the central position. The positioning of the anti-slip member 10 can be easily performed. Therefore, the work of inserting the anti-slip member 10 can be performed smoothly.

<Details of main unit 2>
Next, the detailed structure of the main body section 2 will be explained using FIGS. 3 and 4. In FIG. 3, A31 is a partially enlarged cross-sectional view showing the anti-slip member 10 and the anti-slip accommodating portion 40 in the main body part 2, A32 is an enlarged cross-sectional view of the broken line portion Q in FIG. FIG. 4 is a partially enlarged view showing a stopper housing portion 40. FIG. As shown in FIG. 3, the main body portion 2 includes a non-slip accommodating portion 40, a locked portion 50, a positioning recess 60, and a partition wall 70.

The bottom surface 414 is provided at a position facing the contact surface 12 of the anti-slip member 10, as shown at A31 in FIG. The bottom surface 414 comes into contact with the contact surface 12 of the anti-slip member 10 when the anti-slip member 10 is inserted into the main body portion 2 .

(Locked part 50)
The locked portion 50 is a through hole into which the locking portion 20 is fitted. By forming the locked portion 50 as a through hole, it is possible to prevent cleaning liquid and the like from remaining on the pallet 1 when the main body portion 2 is cleaned. Further, deposits such as dust are less likely to accumulate in the locked portion 50. Note that although a through hole is used here, it may be a depression having a bottom as long as it has a shape that allows the locking convex portion 22 of the locking portion 20 to lock.

The locked portion 50 is in a state where the anti-slip member 10 is placed on the main body 2, more specifically, as shown in A31 of FIG. It is provided at a position facing the locking portion 20 in a state where it is directly above the locking portion 50 . Furthermore, as shown at A33 in FIG. 3, the locked portions 50 are provided at mutually corresponding positions with a positioning recess 60 (described later) in between.

The locked portion 50 has a cross-sectional shape in a plan view formed by a curve (for example, an arc shape) having an apex in the direction from the positioning recess 60 toward the locked portion 50, and as shown in FIG. It is provided with an inclined receiving part 51 which is inclined.

As shown at A31 in FIG. 3, the inclined receiving part 51 is arranged so that the inclined surface 23 of the locking part 20 is in a state where the locking part 20 of the anti-slip member 10 is directly above the locked part 50 of the main body part 2. It is provided in a position opposite to.

Note that although it is explained here that the inclined receiving part 51 is formed in a curved line (for example, an arc shape) having an apex in the direction from the positioning recess 60 toward the locked part 50, the present invention is not limited to this. . For example, the inclined receiving portion 51 may be provided on the surface of the locked portion 50 on the side closer to the positioning recess 60 shown at A33 in FIG. 3 . That is, the inclined receiving portion 51 may be formed in a curved line (for example, an arc shape) having an apex in the direction from the locked portion 50 toward the positioning recess 60. In this case, the locking protrusion 22 and the inclined surface 23 of the anti-slip member 10 have a shape that protrudes from the locking piece 21 toward the positioning protrusion 30 (inward).

(Positioning recess 60)
As shown in FIG. 3, the positioning recess 60 is provided in the central region of the anti-slip accommodating portion 40 between the locked portions 50 provided at positions facing each other. The positioning recess 60 is a through hole into which the positioning protrusion 30 is fitted. By forming the positioning recess 60 as a through hole, it is possible to prevent cleaning liquid and the like from remaining on the pallet 1 when the main body 2 is cleaned. Furthermore, deposits such as dust are less likely to accumulate in the positioning recess 60.

Note that although the positioning convex portion 30 is described as a through hole into which the positioning convex portion 30 is fitted, the positioning concave portion 60 does not have to penetrate through the hole. For example, the positioning recess 60 may be configured as a recess with a concave shape longer than the length from the contact surface 12 of the positioning projection 30 to the lower end of the positioning projection 30. The positioning recess 60 includes a first positioning recess 61 and a second positioning recess 62, as shown in FIG.

As shown at A31 in FIG. 3, the first positioning recess 61 is located at a position opposite to the positioning projection 30 when the positioning projection 30 of the anti-slip member 10 is directly above the positioning recess 60 of the main body 2. provided. The first positioning recess 61 extends in the lateral direction of the anti-slip member 10, which is the first direction, in other words, in the lateral direction (hereinafter simply referred to as the lateral direction) of the anti-slip housing section 40, and extends in the lateral direction of the anti-slip member 10 to prevent slipping. It is formed on the bottom surface 414 of the accommodating part 40.

The first positioning recess 61 is located at a second position as it goes from the outside in the lateral direction, that is, from the side of the first accommodation wall 410 and the second accommodation wall 411 in the longitudinal direction indicated by A33 in FIG. The width in the longitudinal direction (hereinafter simply referred to as the longitudinal direction) is increased.

The second positioning recess 62 extends from the center of the first positioning recess 61 along the convex shape of the second positioning convex 32 in the longitudinal direction (second direction) orthogonal to the transverse direction (first direction). 1. The first positioning recess 61 is formed so as to be partially recessed in the longitudinal direction.

As shown at A33 in FIG. 3, the second positioning recess 62 has a length T3 in the longitudinal direction (second direction) shorter than a length T4 in the short direction (first direction) of the first positioning recess 61. It is formed as follows. Note that although the first direction is described here as the lateral direction, the lateral direction may be the second direction.

By providing the first positioning recess 61 and the second positioning recess 62, when the first positioning convex part 31 is fitted into the first positioning recess 61, the second positioning The convex portion 32 is positioned in the second positioning recess 62. That is, when the anti-slip member 10 is inserted into the main body 2, the positions of the locking portion 20 and the locked portion 50 can be easily aligned, and the anti-slip member 10 can be inserted into the main body 2 in a stable posture. It can be inserted. Therefore, damage to the hole into which the anti-slip member 10 is inserted can be suppressed.

Further, in the work of fitting the anti-slip member 10 into the main body portion 2, it becomes easier to guide the second positioning convex portion 32 to the center position of the first positioning concave portion 61 while aligning the second positioning convex portion 32 along the first positioning concave portion 61. Therefore, positioning of the anti-slip member 10 on the main body portion 2 becomes easier.

(Division wall 70)
As shown in FIG. 3, between the locked part 50 and the positioning recess 60, which are provided at positions facing each other with the positioning recess 60 in between, there is a section that partitions the locked part 50 and the positioning recess 60. A wall 70 is provided. As a result, the partition wall 70 can be constructed in the central region of the anti-slip accommodating portion 40, that is, in the vicinity of the positioning recess 60. Therefore, for example, the strength of the hole can be increased compared to a hole in which the locked portion 50 and the positioning recess 60 communicate with each other.

In addition, in the structure of the said main-body part 2, although the structure in which the anti-slip accommodating part 40 was provided in the main-body part 2 was demonstrated, it is not limited to this. For example, the structure may be such that the main body part 2 is not provided with the anti-slip accommodating part 40, and the locked part 50, the positioning recess 60, and the partition wall 70 are provided on the main plane F of the main body part 2.
<Insertion of the anti-slip member 10 into the anti-slip housing portion 40>
Next, the fitting of the anti-slip member 10 into the anti-slip accommodating portion 40 will be explained using FIGS. 4 to 7. 4 is a diagram showing a state before A41 inserts the non-slip member 10 from directly above, A42 shows a state in which the non-slip member 10 is placed in the non-slip accommodating portion 40 (temporary insertion state), and A43 A44 is a diagram showing a state in which the anti-slip member 10 is fitted into the anti-slip accommodating portion 40, and A44 is a bottom view of A43. In FIG. 5, A51 is a front sectional view corresponding to A41 in FIG. 4, A52 is a front sectional view corresponding to A42 in FIG. 4, and A53 is a front sectional view corresponding to A43 in FIG. . FIG. 6 is a perspective view of A61 showing a state in which the anti-slip member 10 is placed in the anti-slip accommodating portion 40 (temporary fitted state), and A62 is a cross-sectional view of A61 as viewed from the front. In FIG. 7, A71 is a perspective view showing the inclined mounting state of the anti-slip member 10, and A72 is a side sectional view of A71.

As shown in FIG. 4, the anti-slip member 10 is inserted into the anti-slip accommodating portion 40 from directly above downward. Specifically, the anti-slip member 10 is fitted into the anti-slip housing portion 40 in the order of A41→A42→A43 in FIG.

First, the positioning protrusion 30, which is longer than the locking part 20, is guided along the first positioning recess 61. When the positioning convex part 30 is guided along the positioning concave part 60, the second positioning convex part 32 and the second positioning concave part 62 come into contact with each other at the center position of the first positioning concave part 61, so that the anti-slip member 10 The insertion position is determined. When the fitting position of the anti-slip member 10 is determined, the positioning protrusion 30 is fitted into the positioning recess 60.

Next, when the positioning convex portion 30 is inserted, the inclined surface 23 of the locking portion 20 is guided downward along the inclined receiving portion 51 of the locked portion 50. When the inclined surface 23 is guided downward along the inclined receiving part 51 of the locked part 50, the inclined surface 23 slides downward through the inclined receiving part 51 and reaches the state shown by A43 in FIG. When the member 10 is fitted, the locking portion 20 is locked to the locked portion 50.

Note that when the fitting of the anti-slip member 10 into the anti-slip accommodating portion 40 is completed, a water guide hole H is formed between the anti-slip member 10 and the anti-slip accommodating portion 40, as shown at A44 in FIG. Specifically, the water guide hole H is formed by the side wall recess 14 of the anti-slip member 10 and the end region of the positioning recess 60. By forming the water guide holes H in this manner, drainage performance when the main body portion 2 is cleaned with water, cleaning liquid, etc. can be improved. Furthermore, it is possible to prevent cleaning liquid and the like from remaining on the pallet 1 when the main body part 2 is cleaned. Further, deposits such as dust accumulated between the anti-slip member 10 and the main body portion 2 can be easily washed away.

(Temporarily fitted state)
The anti-slip member 10 and the main body 2 create a temporarily fitted state to stabilize the posture of the anti-slip member 10 relative to the main body 2 during a series of steps in which the anti-slip member 10 is fitted into the main body 2. . The temporary fitting state is a state before fitting when the anti-slip member 10 is separated from the main body part 2, as shown by A51 in FIG. This refers to a state in which all of the locking convex portions 22 or inclined surfaces 23 of the member 10 are in contact with the inclined receiving portions 51.

Moreover, since the temporary fitting state is a state in which the locking convex portions 22 or sloped surfaces 23 of all the locking portions 20 are in contact with the slope receiving portions 51, as shown in A61 of FIG. 6, the non-slip member A state in which 10 is tilted is also included. Specifically, as shown in A62 of FIG. 6, this includes a state in which all of the locking convex portions 22 or inclined surfaces 23 are in contact with the inclined receiving portions 51. In other words, when looking at A62 in FIG. 6 from the front, the locking part 20 on the right side is fitted in a lower direction than the locking part 20 on the left side, and the entire anti-slip member 10 is tilted diagonally to the right. include. Note that the anti-slip member 10 may be tilted not only to the right but also to the left.

In this way, even if the anti-slip member 10 is in a temporarily fitted state in which it is inclined diagonally to the right or to the left, the inclined surface 23 and the inclined receiving part 51 will come into contact with each other, and the posture of the anti-slip member 10 will be maintained. It is possible to create a temporary fit state that stabilizes the structure. By creating a temporarily fitted state of the anti-slip member 10, it is possible to suppress the anti-slip member 10 from falling sideways.

Furthermore, by forming the locking convex portion 22 in a curved line having an apex in the protruding direction, the amount of engagement between the locking convex portion 22 and the locked portion 50 can be increased, as shown at A44 in FIG. Therefore, the attachment strength of the anti-slip member 10 to the main body portion 2 can be improved.

In addition, although the locking part 20 is provided with the inclined surface 23 and the locked part 50 is provided with the inclined receiving part 51 here, the non-slip member 10 and the main body part 2 are either one of them. The configuration may include only one of them. That is, the configuration may be such that only the inclined surface 23 is provided, or the structure may be provided only with the inclined receiving portion 51.

(Tilted mounting state)
Next, the inclined mounting state will be explained using FIG. The tilted mounting state refers to a state in which the anti-slip member 10 is caught on the housing wall of the anti-slip accommodating portion 40 and the non-slip member 10 is not in the temporarily fitted state, as shown by A71 in FIG. In other words, all the locking protrusions 22 of the anti-slip member 10 are not in contact with the inclined receiving part 51, and the second positioning protrusion 32 is not fitted into the second positioning recess 62. .

More specifically, as shown at A72 in FIG. 7, the tilted mounting state refers to the first storage state in which the side wall 13 of the anti-slip member 10 is located at the upper end of the first storage wall 410, which is one of the storage walls. The surface 30a of the lower end of the positioning convex portion 30 contacts the upper end 411a of the second housing wall 411a located at the upper end of the second housing wall 411 facing the first housing wall 410. In this state, the angle M between the contact surface 12 of the anti-slip member 10 and the bottom surface 414 of the anti-slip accommodating portion 40 is 30° or more.

Further, the shape of the non-slip housing portion 40 is formed to correspond to the shape of the non-slip member 10 so that the non-slip member 10 is placed in an inclined state. That is, when the anti-slip member 10 is placed in an inclined state with respect to the anti-slip accommodating portion 40, the side wall 13 of the anti-slip member 10 comes into contact with the upper end portion 410a of the first accommodating wall, and the lower end portion of the positioning convex portion 30 The non-slip accommodating portion 40 is formed such that the surface 30a is in contact with the upper end portion 411a of the second accommodating wall.

By molding the anti-slip member 10 and the anti-slip accommodating portion 40 in this manner, when the anti-slip member 10 is placed in an inclined state, the positioning convex portion 30 cannot fit into the positioning recess 60, and the anti-slip member 10 cannot take a stable posture with respect to the main body part 2. When the anti-slip member 10 is placed in a tilted state, the angle M is 30° or more as described above, so that it can be easily confirmed from the appearance that it is placed in a tilted state. Therefore, it becomes easy to determine whether or not the anti-slip member 10 can be inserted into the anti-slip accommodating portion 40 without any problem, and damage to the hole into which the anti-slip member 10 is inserted can be suppressed. Note that if the structure is such that the angle M in the inclined mounting state is 45° or more, it can be more easily confirmed from the appearance that the inclined mounting state is present.

In addition, as shown in A72 of FIG. 7, the anti-slip member 10, in the inclined mounting state, has a straight line L including the upper end side 13a of the side wall 13 in contact with the first housing wall 410 (see A73 of FIG. 7), The distance T5 between the surface 30a of the lower end of the positioning projection 30 and the lower end side 31a of the protrusion, which is the farthest side from the upper end side 13a of the side wall 13, The first housing wall upper end 410a and the second housing wall upper end 411a, which is the upper end of the second housing wall 411 facing the first housing wall 410, may be formed to be longer than the distance T6.

By molding the anti-slip member 10 in this way, when the anti-slip member 10 is placed in an inclined state, the side wall 13 and the upper end portion 410a of the first housing wall are in contact with each other, and the lower end portion of the positioning convex portion 30 is prevented from coming into contact with each other. This facilitates contact between the surface 30a and the upper end portion 411a of the second housing wall.

In this embodiment, the lower end side 31a of the convexity is the farthest side from the upper end side 13a of the side wall 13 among the sides forming the outer periphery of the surface 30a of the lower end of the positioning convex part 30. It is not limited to this. For example, if the positioning protrusion 30 has a tapered shape that narrows the width of the positioning protrusion 30 as it goes in the insertion direction (downward) of the anti-slip member 10, the lower end side 31a of the protrusion has a tapered shape. It may be the farthest side from the upper end side 13a of the side wall 13 on the lower end surface 30a of the positioning convex portion 30 configured in the shape.

Further, the convex lower end is such that the distance between the upper end side 13a and the convex lower end side 31a is longer than the distance T6 between the first housing wall upper end 410a and the second housing wall upper end 411a. A configuration may be adopted in which a plurality of side portions 31a are provided on the surface 30a of the lower end portion of the positioning convex portion 30. In this case, the anti-slip member 10 is placed in an inclined state in which any one of the plurality of convex lower end sides 31a is disposed above the second housing wall upper end 411a.

In the above embodiment, the resin pallet 1 was used as an example of the carrier according to the present invention. , a roll conveyor for conveying the rolled wrap core, etc. may be included. That is, the present invention can be applied as long as the structure has a structure into which the anti-slip member 10 can be fitted.

[Modified example]
Although the embodiments of the present invention have been described in detail above, the above descriptions are merely illustrative of the present invention in all respects. It goes without saying that various improvements and modifications can be made without departing from the scope of the invention. For example, the following changes are possible. In addition, below, the same code|symbol is used regarding the same component as the said embodiment, and description is abbreviate|omitted suitably about the point similar to the said embodiment.

For example, in the embodiment described above, the anti-slip member 10 is integrally molded from the same material. However, the anti-slip member 10 does not need to be limited to such an example, and may be appropriately selected depending on the embodiment.

FIG. 8 is a diagram showing a non-slip member 100 according to a modified example, where A81 is an exploded view of the non-slip member 100 according to the modified example, and A82 is a cross-sectional view in the longitudinal direction of the non-slip member 100 according to the modified example. .

As shown in FIG. 8, the anti-slip member 100 includes a base portion 80 molded from polyolefin resin (first material), which is the same material as the main body portion 2. The anti-slip member 100 also includes an anti-slip layer 81 provided on the upper surface of the base 80 and made of styrene-butadiene rubber (SBR), thermoplastic elastomer, or the like (second material), which is more flexible than the first material. .

When molding the anti-slip member 100 separately into the base 80 and the anti-slip layer 81, for example, the base 80 is molded by injection molding, and then the molded base 80 is placed in a mold. Then, by injection molding the anti-slip layer 81 thereon, the anti-slip member 100 including the base 80 and the anti-slip layer 81 is formed.

According to the above configuration, the anti-slip member 100 includes the base 80 and the anti-slip layer 81 that is more flexible than the base 80, so that the anti-slip layer 81 that is more flexible than the base 80 is placed on the upper side of the base 80. , it is easier to exhibit the anti-slip effect. Further, the anti-slip member 100 can be made less likely to harden or deteriorate over time than when the entire anti-slip member 10 is molded from a soft resin or the like.

Further, in the case of the anti-slip member 100 including the base 80 and the anti-slip layer 81, as shown in A81 of FIG. 8, the anti-slip member 100 has an adhesive surface 90 for bonding the base 80 and the anti-slip layer 81. Further, in the adhesive surface 90, an adhesive surface 91 is provided in a region between the locking part 20 and the positioning convex part 30, at least a part of which is depressed toward the contact surface 12 from the other adhesive surface 90. It may be. In A81 of FIG. 8, four adhesive surfaces 91 are provided that are recessed toward the contact surface 12 from the other adhesive surfaces 90. However, this is just an example, and the number may be one or five or more.

According to the above configuration, there is an adhesive surface 90 between the base portion 80 and the anti-slip layer 81, and another adhesive surface is provided in the area between the locking portion 20 and the positioning convex portion 30 of the adhesive surface 90. The adhesive surface 91 is recessed from 90 toward the contact surface 12.

As a result, the ratio of the anti-slip layer 81 to the base 80 is higher on the recessed adhesive surface 91 than on the other adhesive surfaces 90. That is, the region having the depressed adhesive surface 91 is more easily deformed than the other adhesive surfaces 90. Therefore, the anti-slip member 100 can have a structure that facilitates deformation when the locking portion 20 is inserted into the locked portion 50 while ensuring rigidity at necessary locations.

The present invention is not limited to the embodiments described above, and various modifications can be made within the scope of the claims, and embodiments obtained by appropriately combining technical means disclosed in different embodiments. are also included within the technical scope of the present invention.
