The lower nip part 30b has a size and a shape that allow the lower pallet 10c to be inserted into and removed from the fork insertion port 13.

  In a state where the pallet fixture 2 is not attached to the pallet 10, the distance between the upper clamping part 30a and the fitting clamping part 25 is the thickness of the grounding deck portion 15 of the upper pallet 10b and the fitting pallet. It is set to be smaller than the total thickness of the loading deck portion 14 of 10a.

  When the pallet fixture 2 is not attached to the pallet 10, the distance between the lower clamping part 30b and the fitting clamping part 25 is the thickness of the mounting deck portion 14 of the lower pallet 10c and the fitting. It is set smaller than the total thickness of the ground deck portions 15 of the pallet 10a.

Note that the distance between the upper clamping part 30a and the fitting clamping part 25 and the distance between the lower clamping part 30b and the fitting clamping part 25 depend on the thickness of the mounting deck portion 14 and the grounding. varies depending on the thickness of the deck section 15, for example, is less than 55 m m or 65 m m.

  And when the pallet fixing tool 2 is attached to a pallet group, the fitting clamping part 25 is fitted by the fork insertion port 13 of the fitting pallet 10a. By fitting the fitting clamping part 25 into the fork insertion port 13, the position of the upper clamping part 30a with respect to the fitting pallet 10a is determined. Moreover, the position of the lower stage clamping part 30b with respect to the fitting pallet 10a is determined by fitting the fitting clamping part 25 in the fork insertion port 13.

  Moreover, when the fitting clamping part 25 is fitted by the fork insertion port 13, the upper stage clamping part 30a is inserted in the fork insertion port of the upper stage pallet 10b.

The material for forming the pallet fixture 2 is that the mounting deck portion 14 of one pallet 10 and the grounding deck portion 15 of the other pallet 10 are between the fitting sandwiching portion 25 and the lower sandwiching portion 30b. It is preferable to be elastically deformed to such an extent that can be spread. For example, a synthetic resin such as polypropylene or polyethylene having a flexural modulus of 600 MPa or more and 1800 MPa or less is suitable for the material for forming the pallet fixture 2. In the case of the pallet fixture 2 that can be elastically deformed in this way, the allowable range of the tolerance of the thickness of the mounting deck portion 14 and the tolerance of the thickness of the grounding deck portion 15 is widened. A tolerance of about 20% with respect to the target dimension is allowed.

Next, an example of the structure of the pallet fixture 2 will be described with reference to FIGS. 4 and 5.
FIG. 4 is a diagram showing a side structure of the pallet fixture 2 as seen from the pallet fixture 2 from one side in the horizontal direction. FIG. 5 is a pallet fixture as seen from the pallet fixture 2 from the other side in the horizontal direction. It is a figure which shows the side structure of 2. As shown in FIGS. 4 and 5, the pallet fixture 2 has a structure that is symmetric with respect to the vertical plane. Therefore, below, with reference to FIG. 4, an example of the side structure of the pallet fixture 2 when the pallet fixture 2 is viewed from one side in the horizontal direction will be described.

  As shown in FIG. 4, the pallet fixture 2 has a single flat plate wall 21, and the single flat plate wall 21 includes a main body portion 23, a fitting pinch portion 25, an upper pinch portion 30 a, and a lower step pinch. It is common to the part 30b.

The object to be clamped is sandwiched. In the state where the pallet fixture 2 is attached to the pallet 10, each part of the pallet fixture 2 is arranged so that the distance between the fitting and clamping portion 25 and the upper clamping portion 30 a increases, and the fitting and clamping portion. The stress is received in the direction in which the distance between 25 and the lower clamping part 30b increases. On the other hand, when handling the pallet fixture 2 or manufacturing the pallet fixture 2, it is preferable that the amount of material used for manufacturing the pallet fixture 2 is small. In these respects, if the flat plate wall 21 has the above-described structure, the amount of material used for manufacturing the pallet fixture 2 is suppressed, and the fitting and holding portion is within the range of the amount of material used. The load resistance is enhanced along the direction in which the distance between the upper and lower clamping portions 30a increases and the direction in which the distance between the fitting and clamping portions 25 and 30b increases.

  Of the peripheral wall 22, the part constituting the fitting and holding part 25 has a band shape extending along the stacking direction of the pallets 10, and the part connecting the middle upper holding wall 22 c 1 and the middle lower holding wall 22 c 2. This is the intermediate connecting wall 22c3. The corner formed by the middle upper clamping wall 22c1 and the middle coupling wall 22c3 has a chamfered shape, and the corner formed by the middle lower clamping wall 22c2 and the middle coupling wall 22c3 is also chamfered. Has the shape. If it is such a structure, when the fitting clamping part 25 is inserted in the fork insertion port 13 of the fitting pallet 10a, contact | abutting of the fitting clamping part 25 and the mounting deck part 14, or fitting clamping The contact between the portion 25 and the ground deck portion 15 is prevented from being prevented from being inserted.

  The part which comprises the upper stage clamping part 30a among the surrounding walls 22 has the upper stage clamping wall 22a which is an example of a 2nd clamping wall. The upper clamping wall 22a has a band shape extending substantially along the fork insertion direction, and faces the middle upper clamping wall 22c1.

  The part which comprises the lower stage clamping part 30b among the surrounding walls 22 has the lower stage clamping wall 22b which is an example of a 2nd clamping wall. The lower stage clamping wall 22b has a band shape extending substantially along the fork insertion direction and faces the middle stage lower clamping wall 22c2.

  Here, in the pallet fixture 2, the mounting and clamping unit 25 and the upper clamping unit 30 a press the object to be clamped, so that the mounting deck part 14 and the grounding deck part 15 are clamped therebetween. Moreover, the mounting deck part 25 and the lower stage clamping part 30b press the object to be clamped, so that the mounting deck part 14 and the ground deck part 15 are clamped therebetween. Therefore, in order to stabilize the fixed state of the pallets 10, it is preferable that each of the fitting and holding part 25, the upper stage holding part 30 a, and the lower stage holding part 30 b has a large area in contact with the object to be held. On the other hand, in the pallet fixture 2, for the purpose of suppressing the amount of use of the material and ensuring load resistance, most of the fitting and clamping part 25, the upper stage clamping part 30a, and the lower stage clamping part 30b are as described above. The flat wall 21 is used. And since the flat plate wall 21 has the flat plate shape extended along the direction where the pallet 10 is piled up, the cross-sectional area with respect to the direction which presses a clamping object becomes small naturally. In this regard, if the peripheral wall 22 has the above-described structure, the middle upper clamping wall 22c1, the middle lower clamping wall 22c2, and the upper clamping wall 22a along the direction in which the mounting deck portion 14 and the grounding deck portion 15 spread. And the lower stage clamping wall 22b spreads. Therefore, even if the flat plate wall 21 is employed for the purpose of suppressing the amount of material used for the pallet fixture 2 and ensuring load resistance, the fixed state of the pallets 10 can be stabilized.

  The upper clamping wall 22 a has a recess 34 that is recessed in a direction away from the fitting clamping part 25, and the lower clamping wall 22 b also has a recess 34 that is recessed in a direction away from the fitting clamping part 25. In the upper clamping wall 22a, the recess 34 extends from a portion facing the tip of the fitting clamping part 25 toward the tip of the upper clamping part 30a. Further, in the lower clamping wall 22b, the recess 34 also extends from the portion facing the tip of the fitting and clamping part 25 toward the tip of the lower clamping part 30b.

  Here, each of the fitting clamping part 25, the upper clamping part 30a, and the lower clamping part 30b may be inserted into the fork insertion port 13 along the fork insertion direction, or the fork insertion, for example. You may insert in the fork insertion port 13 along the direction which cross | intersects a direction. At this time, if the upper holding wall 22a has a recess 34, the distance between the upper holding wall 22a and the middle upper holding wall 22c1 is wider than other parts in the range where the recess 34 is formed. . Further, if the lower clamping wall 22b has a recess 34, the distance between the lower clamping wall 22b and the middle lower clamping wall 22c2 is also larger than other parts in the range where the recess 34 is formed. . As a result, when the upper clamping part 30a is inserted into the fork insertion port 13 along the direction intersecting with the fork insertion direction, there is a range in which the relative position between the upper clamping part 30a and the ground deck part 15 can be taken. It expands by the amount of the recess 34. Further, the range in which the relative position between the lower holding portion 30b and the mounting deck portion 14 can be taken even when the lower holding portion 30b is inserted into the fork insertion port 13 along the direction intersecting the fork insertion direction. Expands by the amount of the recess 34. Therefore, compared to the configuration in which the recess 34 is not formed, each of the fitting and clamping part 25, the upper stage clamping part 30a, and the lower stage clamping part 30b is inserted into the fork along a direction intersecting the fork insertion direction. It becomes easy to insert into the mouth 13.

  In the fitting and clamping part 25, the width of the part closest to the main body part 23 among the widths along the longitudinal direction of the main body part 23 is the middle base end width H1a. The middle base end width H1a is equal to the width along the longitudinal direction of the main body 23 at the fork insertion port 13 of the fitting pallet 10a.

  In the fitting and clamping part 25, the width of the part farthest from the main body part 23 among the widths along the longitudinal direction of the main body part 23 is the middle-stage tip width H1b. The middle stage leading end width H1b is slightly smaller than the middle stage base end width H1a.

In the fitting and clamping part 25, the width along the longitudinal direction of the main body part 23 decreases as the distance from the main body part 23 decreases, and gradually decreases from the middle base end width H1a to the middle stage front end width H1b. That is, the fitting sandwiching portion 25 has a tapered shape that becomes narrower in the longitudinal direction of the main body portion 23 from the proximal end of the fitting sandwiching portion 25 toward the distal end of the fitting sandwiching portion 25. The middle upper clamping wall 22c1 constituting the fitting clamping part 25 preferably has an angle between 1 ° and 8 ° as an angle between the extending direction of the middle upper clamping wall 22c1 and the horizontal direction. Further, the middle lower clamping wall 22c2 constituting the fitting clamping part 25 may have an angle between 1 ° and 8 ° as an angle between the extending direction of the middle lower clamping wall 22c2 and the horizontal direction. preferable. If it is such a structure, when the fitting clamping part 25 is inserted in the fork insertion port 13 of the fitting pallet 10a, since the fitting clamping part 25 has a taper shape, the fitting clamping part 25 Insertion proceeds smoothly, and the base end of the fitting sandwiching portion 25 is easily fitted into the fork insertion port 13.

  The amount protruding from the main body portion 23 of the upper clamping portion 30a is larger than the amount protruding from the main body portion 23 of the fitting clamping portion 25. Further, the amount of the lower clamping part 30 b protruding from the main body part 23 is larger than the amount of the fitting clamping part 25 protruding from the main body part 23. The amount protruding from the main body portion 23 of the upper clamping portion 30a is substantially equal to the amount protruding from the main body portion 23 of the lower clamping portion 30b. For example, the length D2 along the longitudinal direction of the upper clamping part 30a and the length D2 along the longitudinal direction of the lower clamping part 30b are larger than the length D1 along the longitudinal direction of the fitting clamping part 25. The length D2 is approximately twice the length D1.

  As described above, the fitting and clamping unit 25, the upper stage clamping unit 30a, and the lower stage clamping unit 30b are often inserted into the fork insertion port 13 along a direction intersecting the fork insertion direction. At this time, if the length D2 and the length D1 are different from each other, the fitting and holding portion 25, the upper holding portion 30a, and the lower holding portion are compared with a configuration in which these lengths are the same. It is easy to insert each of 30b into the fork insertion port 13 along a direction intersecting with the fork insertion direction.

  In addition, the fitting clamping part 25 inserted by the fork insertion port 13 has the function which determines the position of the upper stage clamping part 30a with respect to the fitting pallet 10a, and determines the position of the lower stage clamping part 30b with respect to the fitting pallet 10a. Have. Therefore, it is preferable that the fitting sandwiching portion 25 fitted to the fork insertion port 13 is not displaced relative to the fork insertion port 13. Further, in the configuration in which the length D2 and the length D1 are different from each other, in order to increase the ease of mounting the pallet fixture 2, the insertion of the second clamping part such as the upper clamping part 30a and the lower clamping part 30b is inserted. It is preferable that the length D1 is shorter than the length D2 so as to precede the fitting and holding portion 25.

  In addition, the greater the difference between the length D2 and the length D1, the greater the angle between the insertion direction of the fitting clamping part 25, the upper clamping part 30a, and the lower clamping part 30b and the fork insertion direction. The permissible range is also wide, and it is possible to insert the fitting and clamping part 25, the upper stage clamping part 30a, and the lower stage clamping part 30b at an angle with respect to the fork insertion direction. On the other hand, the shorter the length D <b> 1 along the longitudinal direction of the fitting / holding portion 25, the weaker the fitting strength between the fitting / holding portion 25 and the fork insertion port 13. Further, the length D2 along the longitudinal direction of the upper sandwiching portion 30a and the length D2 along the longitudinal direction of the lower sandwiching portion 30b are limited to a range in which the mounting deck portion 14 and the grounding deck portion 15 can be pressed. It is done. Therefore, the length D2 along the longitudinal direction of the upper clamping part 30a and the length D2 along the longitudinal direction of the lower clamping part 30b are 1 of the length D1 along the longitudinal direction of the fitting clamping part 25. It is preferably 5 times or more and 2.5 times or less.

In the longitudinal direction of the main body 23, the width H2 of the upper clamping part 30a is lower than the height of the fork insertion port 13 of the pallet 10, and the width H2 of the lower clamping part 30b is also the fork insertion of the pallet 10. It is lower than the height of the mouth 13. Such a difference between the width H2 and the middle stage tip width H1b is also configured to allow the fitting and clamping part 25, the upper stage clamping part 30a, and the lower stage clamping part 30b to be inclined and inserted with respect to the fork insertion direction. is there. That is, as the difference between the width H2 and the middle tip width H1b is larger, the allowable range of the angle formed by the insertion direction of the fitting clamping part 25, the upper clamping part 30a, and the lower clamping part 30b and the fork insertion direction Is also wide. On the other hand, the lower the width H2 of the upper clamping part 30a and the width H2 of the lower clamping part 30b, the weaker the pressing force applied by the upper clamping part 30a and the pressing force applied by the lower clamping part 30b. Moreover, the middle stage front end width H1b of the fitting / clamping part 25 is limited to a range in which the fitting / clamping part 25 and the fork insertion port are fitted. Therefore, the width H2 of the width H2 and lower clamping portions 30b of the upper clamping portion 30a, middle tip width H1b of Hamagokyo sandwiching member 25 is preferably not more than 2.5 times 1.5 times or more.

  The tip 33 of the upper clamping part 30a is formed in a tapered shape that becomes narrower toward the tip. For this reason, when the upper stage clamping part 30a is inserted in the fork insertion port 13 of the pallet 10, it is suppressed that the upper stage clamping part 30a is caught by the grounding deck part 15. FIG. In addition, the tip of the lower clamping part 30b is also formed in a tapered shape that becomes narrower toward the tip, like the upper clamping part 30a. For this reason, when the lower stage clamping part 30b is inserted in the fork insertion port 13 of the pallet 10, it is suppressed that the lower stage clamping part 30b is caught by the mounting deck part 14. FIG.

  As shown in FIG. 6, in the middle support wall 21c, the portion connected to the middle upper holding wall 22c1 and the portion connected to the middle lower holding wall 22c2 include the middle upper holding wall 22c1 and the lower middle side. A long hole 26 extending along the extending direction of the holding wall 22c2 is formed. The two long holes 26 are used for draining water, and are escape holes for the middle stage upper sandwiching wall 22c1 and the middle stage lower sandwiching wall 22c2. The middle stage upper sandwiching wall 22c1 and the middle stage lower sandwiching wall 22c2 Encourage elastic deformation in the direction of approaching each other. Four drain holes 31 are formed in the upper support wall 21a at intervals along the direction in which the upper support wall 21a protrudes, and the lower support wall 21b has a direction in which the lower support wall 21b protrudes. Four drain holes 31 are formed at intervals. Further, three drain holes 36 are formed in a portion of the flat wall 21 constituting the handle portion 35.

  The fitting clamping part 25 has two reinforcing ribs 27 that connect the middle support wall 21c and the middle upper clamping wall 22c1, and two reinforcements that connect the middle support wall 21c and the middle lower clamping wall 22c2. Ribs 27 are provided. The reinforcing rib 27 is a rib having a triangular shape having a hypotenuse between the middle support wall 21c and the middle upper clamping wall 22c1, and the mechanical strength of the corner formed by the middle support wall 21c and the middle upper clamping wall 22c1. Is supplemented. The reinforcing rib 27 is a rib having a triangular shape having a hypotenuse on the middle stage support wall 21c and the middle stage lower holding wall 22c2, and is formed at the corner formed by the middle stage supporting wall 21c and the middle stage lower holding wall 22c2. Compensates for mechanical strength. In order to compensate for such mechanical strength at the corners, the width of the reinforcing ribs 27 in the horizontal direction is preferably 2/3 of the width of the middle upper clamping wall 22c1.

  The two reinforcing ribs 27 arranged along the fork insertion direction are located in the vicinity of one long hole 26 and sandwich the long hole 26 in the fork insertion direction. With the configuration in which the two reinforcing ribs 27 are provided at such positions, when the fitting sandwiching portion 25 is inserted into the fork insertion port 13 of the pallet 10, the middle upper sandwiching wall 22c1 and the middle lower sandwiching wall 22c2 However, the reinforcing ribs 27 ensure the mechanical strength that is easily elastically deformed in the direction approaching each other in the vicinity of the long hole 26 and that is necessary for the elastic deformation.

  In the upper clamping part 30a, four oblique ribs 32 that connect the peripheral walls 22 facing each other are located between the drain holes 31 adjacent to each other. In each of the four slanted ribs 32, the portion that is on the distal end side of the upper holding portion 30a is located closer to the fitting holding portion 25 than the portion that is on the proximal end side of the upper holding portion 30a.

  Also in the lower clamping part 30b, the four oblique ribs 32 that connect the peripheral walls 22 facing each other are located between the adjacent drain holes 31. In each of the four oblique ribs 32, the portion that is on the distal end side of the lower-stage sandwiching portion 30b is located closer to the fitting sandwiching portion 25 than the portion that is on the proximal end side of the lower-stage sandwiching portion 30b.

  With such a configuration having the oblique ribs 32, it is assumed that when the upper clamping part 30a is inserted into the fork insertion port 13 of the pallet 10, the tip of the upper clamping part 30a is deformed in a direction away from the fitting clamping part 25. However, the stress applied to the peripheral wall 22 is relaxed. Further, when the lower stage clamping part 30b is inserted into the fork insertion port 13 of the pallet 10, even if the tip of the lower stage clamping part 30b is deformed in the direction away from the fitting clamping part 25, the stress applied to the peripheral wall 22 is increased. Alleviated. In addition, the number of the diagonal ribs 32 which the upper stage clamping part 30a has, and the number of the diagonal ribs 32 which the lower stage clamping part 30b has are not limited to four, and may be one or more and three or less. It may be.

  Also in the handle portion 35, two ribs 37 that connect the peripheral walls 22 facing each other are located between the drain holes 36 adjacent to each other. With the configuration having such ribs, the peripheral wall 22 can be supported by the ribs 37 when the user grips and uses the handle portion 35.

  The attachment method of the pallet fixture 2 will be described with reference to FIGS. First, a method of inserting the pallet fixture 2 into the pallet 10 along the fork insertion direction will be described among the attachment methods of the pallet fixture 2.

  As shown in FIG. 7, when the pallet fixing tool 2 fixes the pallet 10, first, the first pallet 10 along the fork insertion direction is placed on the three-stage pallet 10 aligned along the stacking direction of the pallets 10. The pallet fixture 2a is inserted. Further, the second pallet fixture 2b is inserted into the three-stage pallet 10 arranged along the stacking direction of the pallets 10 along the fork insertion direction.

  At this time, in the direction in which the pallets 10 are stacked, the middle-stage leading end width H1b of the fitting / holding portion 25 and the width Hp of the fork insertion port 13 are substantially the same. Further, in the direction in which the pallets 10 are stacked, the width W1 of the gap between the fitting sandwiching portion 25 and the upper sandwiching portion 30a is a width Wp1 that is the sum of the width of the mounting deck portion 14 and the width of the grounding deck portion 15. It is almost the same. Further, the width W1 of the gap between the fitting sandwiching portion 25 and the lower sandwiching portion 30b is also a width Wp1 that is the sum of the width of the mounting deck portion 14 and the width of the grounding deck portion 15 in the direction in which the pallets 10 are stacked. Is almost the same.

  As shown in FIG. 8, when the first pallet fixture 2a is inserted into the fork insertion port 13, the fitting clamping part 25 of the first pallet fixture 2a is connected to the fork insertion port 13 of the fitting pallet 10a. To be fitted. Further, when the second pallet fixture 2b is inserted into the fork insertion port, the fitting sandwiching portion 25 of the second pallet fixture 2b is fitted into the fork insertion port 13 of the other fitting pallet 10a. .

  When the first pallet fixture 2a is inserted into the fork insertion port 13, the upper nip portion 30a of the first pallet fixture 2a abuts on the grounding deck portion 15 of the upper pallet 10b. When the second pallet fixture 2b is inserted into the fork insertion port 13, the upper nip portion 30a of the second pallet fixture 2b abuts on the grounding deck portion 15 of the other upper pallet 10b.

  Here, the grounding deck portion 15 has an inclined surface 12 s having a shape inclined from the fork insertion port 13 toward the inside of the pallet 10. Since the inclined surface 12s is a path on which the wheel of the pallet truck rides, normally, the gradient gradually increases along the fork insertion direction so that the wheel smoothly advances from the fork insertion port 13 to the inside of the pallet 10. have. Therefore, when the pallet fixture 2 is inserted into the fork insertion port 13, the upper clamping portion 30 a of the pallet fixture 2 comes into contact with the inclined surface 12 s of the ground deck portion 15.

  At this time, since the inclined surface 12s has a gradually increasing gradient along the fork insertion direction, the upper holding portion 30a that contacts the inclined surface 12s is gradually displaced upward along the inclined surface 12s. While passing through the fork insertion port 13. Along with this, the gap between the fitting sandwiching section 25 and the upper sandwiching section 30a is gradually expanded by the mounting deck portion 14 and the ground deck portion 15. Then, the upper deck holding portion 30a passing through the fork insertion port 13 of the upper pallet 10b gradually moves the grounding deck portion 15 toward the fitting holding portion 25 fitted into the fork insertion port 13 of the fitting pallet 10a. Press. As a result, the mounting deck portion 14 and the grounding deck portion 15 are sandwiched by the fitting sandwiching portion 25 and the upper sandwiching portion 30a, and such sandwiching proceeds smoothly by the slope of the inclined surface 12s.

  Since the plurality of ribs constituting the mounting deck portion 14 have a shape that gradually increases along the fork insertion direction, the lower clamping portion 30b that abuts against these ribs also has a rib height. The fork insertion port 13 is passed while gradually moving downward. Accordingly, the gap between the fitting sandwiching portion 25 and the lower sandwiching portion 30b is gradually pushed and widened by the mounting deck portion 14 and the ground deck portion 15. Then, the upper deck holding portion 30a passing through the fork insertion port 13 of the upper pallet 10b gradually moves the grounding deck portion 15 toward the fitting holding portion 25 fitted into the fork insertion port 13 of the fitting pallet 10a. Press. As a result, the mounting deck portion 14 and the ground deck portion 15 are sandwiched between the fitting sandwiching portion 25 and the upper sandwiching portion 30a, and such sandwiching proceeds smoothly due to the difference in height between the plurality of ribs.

Next, a method for inserting the pallet fixture 2 into the pallet 10 along the direction intersecting the fork insertion direction will be described.
As shown in FIG. 9, when fixing the pallet 10, first, the three-stage pallet 10 aligned along the stacking direction of the pallets 10 is placed in a direction intersecting the fork insertion direction, for example, obliquely upward. The first pallet fixture 2a is inserted. In addition, the second pallet fixture 2b is inserted into the three-stage pallets 10 arranged along the stacking direction of the pallets 10 along the direction that also intersects the fork insertion direction.

  When the first pallet fixture 2a is inserted into the fork insertion port 13, the fitting and clamping portion 25 of the first pallet fixture 2a is fitted into the fork insertion port 13 of the fitting pallet 10a, and the first pallet The upper clamping portion 30a of the fixture 2a abuts on the ground deck portion 15 of the upper pallet 10b.

  Further, when the second pallet fixture 2b is inserted into the fork insertion port, the fitting sandwiching portion 25 of the second pallet fixture 2b is fitted into the fork insertion port 13 of the other fitting pallet 10a, The upper nip part 30a of the second pallet fixture 2b is in contact with the grounding deck portion 15 of the other upper pallet 10b.

  At this time, since the pallet fixture 2 is inserted while being inclined with respect to the fork insertion direction, the distance between the upper clamping portion 30a and the mounting deck portion 14 becomes shorter as the pallet fixture 2 is inserted. Become. In this regard, with the above-described configuration, since the upper holding wall 22a has the recess 34, the distance between the upper holding portion 30a and the mounting deck portion 14 is increased by the depth of the recess 34. As a result, when the pallet fixture 2 is inserted, mechanical interference between the upper holding wall 22a and the mounting deck portion 14 is suppressed, and the holding by the fitting holding portion 25 and the upper holding portion 30a proceeds smoothly.

  For example, when a strong wind is blown onto the stacked pallets 10, the plurality of pallets 10 fixed by the pallet fixture 2 receive the wind as one set. As a result, for example, even when one pallet 10 is blown away by wind, the pallet 10 fixed by such a pallet fixing tool 2 is not blown away. In particular, in a synthetic resin pallet that is lighter than a wooden pallet, the force required to displace one pallet is small, so the effect of the pallet fixture 2 is remarkable. Further, when the wheel arrangement hole 12H for the pallet truck is formed in the ground deck board 12 as in the case of the single-sided synthetic resin pallet, the force required for the displacement of one pallet is further reduced. The effect obtained by the pallet fixing tool 2 is more remarkable. And since the inclined surface 12s through which the wheel of a pallet truck passes is formed in the synthetic resin pallet used on one side, the insertion of the upper clamping part 30a and the fitting clamping part 25 and the upper clamping part 30a Clamping proceeds smoothly compared to other types of pallets.

As described above, according to the first embodiment, the following effects can be obtained.
(1) By attaching one pallet fixing tool 2, the three pallets 10 adjacent to each other are fixed in the stacking direction of the pallets 10.

  (2) Since the long hole 26 formed in the fitting sandwiching portion 25 functions as a relief hole of the peripheral wall 22, the load required to insert the fitting sandwiching portion 25 into the fork insertion port 13, and the fitting The force required for fitting the holding part 25 is suppressed.

  (3) A portion of the peripheral wall 22 in the vicinity of the elongated hole 26 that is easily elastically deformed is mechanically reinforced by the reinforcing rib 27. Therefore, the force required for fitting of the fitting / clamping part 25 is suppressed, and the mechanical strength of the fitting / clamping part 25 is supplemented.

  (4) A portion of the flat plate wall 21 near the elongated hole 26 that is easily elastically deformed is mechanically reinforced by the reinforcing rib 27. Therefore, the force required for fitting of the fitting / clamping part 25 is suppressed, and the mechanical strength of the fitting / clamping part 25 is supplemented.

  (5) When the pallet fixture 2 is inserted into the fork insertion port 13 along the direction intersecting the fork insertion direction, the upper holding wall 22a having the recess 34 is inserted along the grounding deck portion 15. As a result, mechanical interference between the pallet fixture 2 and other members is suppressed.

  (6) The lower stage clamping part 30b which the 1st pallet fixing tool 2a has, and the upper stage clamping part 30a which the 2nd pallet fixing tool 2b has are inserted in the fork insertion port 13 of the pallet 10 which is mutually common. Therefore, for example, it is possible to fix the n-stage pallet 10 (n is an integer of 2 or more) with (n−1) pallet fixtures 2.

(7) One pallet fixture 2 can fix three pallets 10.
(Second Embodiment)
With reference to FIGS. 10-13, the pallet fixing tool of 2nd Embodiment is demonstrated. Note that the pallet fixing tool of the second embodiment is mainly different from the first embodiment in that the number of the second holding portions of the pallet fixing tool is one. Therefore, below, it demonstrates centering around difference with 1st Embodiment, attaches | subjects the code | symbol same about the structure which has the function similar to the structure demonstrated in 1st Embodiment, and abbreviate | omits the description.

  As shown in FIG. 10, the pallet fixture 3 includes a main body portion 23, a fitting and holding portion 25, one second holding portion 30, and a handle portion 35. The fitting sandwiching portion 25 and the second sandwiching portion 30 protrude from the main body portion 23 in the same direction, and one each is provided on the main body portion 23. The main body part 23 protrudes along the longitudinal direction of the main body part 23 from the base part of the fitting and clamping part 25.

  As shown in FIG. 11, the amount by which the main body portion 23 projects from the base portion of the fitting and holding portion 25 is less than or equal to half of the width W1 of the gap between the fitting and holding portion 25 and the second holding portion 30. preferable. With such a configuration of the main body 23, when the pallet fixture 3 is inserted into the fork insertion port 13 of the pallet 10, two portions of the main body 23 abut on the side surface of one pallet 10, and It is suppressed that the main-body part 23 becomes unnecessarily long.

  The pallet fixing tool 3 sets each of the two pallets 10 to which the pallet fixing tool 3 is attached to either the fitting pallet 10a or the upper pallet 10b. For example, the pallet fixture 3 sets the first pallet 10 to the upper pallet 10b which is an example of the second pallet. Further, the pallet fixture 3 sets the second pallet 10 to the fitting pallet 10a which is an example of the first pallet. For the pallet fixture 3, the mounting deck portion 14 of the fitting pallet 10a is an example of a first deck portion, and the grounding deck portion 15 of the upper pallet 10b is an example of a second deck portion.

With reference to FIG. 12 and FIG. 13, the attachment method of the pallet fixture 3 is demonstrated with an effect | action of the pallet fixture 3. FIG.
As shown in FIG. 12, when the pallet fixing tool 3 fixes the pallet 10, first, the pallet is fixed to the two-stage pallet 10 aligned along the stacking direction of the pallets 10 along the fork insertion direction. Tool 3 is inserted.

  As shown in FIG. 13, when the pallet fixture 3 is inserted into the fork insertion port 13, the fitting sandwiching portion 25 of the pallet fixture 3 is fitted into the fork insertion port 13 of the fitting pallet 10 a. The Moreover, the 2nd clamping part 30 of the pallet fixing tool 3 contact | abuts to the grounding deck part 15 in the fork insertion port 13 of the upper stage pallet 10b. Then, the second sandwiching portion 30 passing through the fork insertion port 13 of the upper pallet 10b gradually moves the grounding deck portion 15 toward the fitting sandwiching portion 25 fitted into the fork insertion port 13 of the fitting pallet 10a. Press on. As a result, the mounting deck portion 14 and the grounding deck portion 15 are sandwiched between the fitting sandwiching portion 25 and the second sandwiching portion 30.

  As a result, the pallet fixture 3 can fix the two stacked pallets 10 together. For example, when a strong wind is blown onto the stacked pallets 10, the plurality of pallets 10 fixed by the pallet fixture 3 receive the wind as one set. Therefore, for example, even when one pallet 10 is blown away by wind, the pallet 10 fixed by such a pallet fixing tool 2 is not blown away.

As mentioned above, according to the said 2nd Embodiment, in addition to the effect according to said (1)-(7), the following effects are acquired.
(8) Since the pallet fixture 3 has the fitting clamping part 25 and the 2nd clamping part 30 one each, compared with the pallet fixing tool 2 of 1st Embodiment, the size of a pallet fixture is reduced. can do.

  (9) Since the pallet fixture 3 has the fitting clamping part 25 and the 2nd clamping part 30 one each, when fixing a some pallet, two pallets which are the minimum units are fixed. Therefore, the degree of freedom is increased when selecting the fixed parts of the stacked pallets. Further, the pallet fixing tool 3 can be easily inserted into the fork insertion port 13 as compared with the pallet fixing tool 2 of the first embodiment.

In addition, the said embodiment can be implemented with the following forms which changed this suitably.
When the pallet fixture 2 is not attached to the pallet 10, the distance between the upper clamping part 30a and the fitting clamping part 25 is the thickness of the grounding deck portion 15 of the upper pallet 10b and the fitting. It may be equal to or greater than the sum of the thicknesses of the mounting deck portions 14 of the pallet 10a. At this time, the upper stage clamping portion 30a may have a shape that can press the ground deck portion 15 toward the fitting pallet 10a. For example, the upper stage clamping part 30a has a front end part that protrudes in the fork insertion direction from the fitting holding part 25, and there is a gap between the upper stage clamping part 30a and the grounding deck part 15 at a part other than the front end part. Only the tip end portion of the upper holding portion 30a formed may be configured to press the ground deck portion 15.

  The grounding deck portion 15 inherently possessed by the single-sided pallet has an inclined surface 12s on the front side in the fork insertion direction so that the wheels of the pallet truck can easily enter the fork insertion port 13. In order to make it easier for the wheels of the pallet truck to enter the wheel arrangement hole 12H, such a grounding deck portion 15 usually gradually increases in height toward the back side in the fork insertion direction and toward the back side in the fork insertion direction. It has a back side inclined surface with a decreasing gradient. At this time, it is preferable that the distal end portion of the upper stage clamping portion 30a has a hook shape whose height is lower toward a portion closer to the distal end. The upper holding part 30a having such a structure can press the ground deck 15 against the fitting pallet 10a through contact between the upper holding part 30a inserted into the fork insertion port 13 and the rear inclined surface. is there. In addition, with such a configuration, the upper stage clamping part 30a inserted into the fork insertion port 13 by the engagement between the front end part of the upper stage clamping part 30a and the back side inclined surface of the ground deck part 15 becomes the fork insertion. It is also possible to suppress the exit from the mouth 13.

  In the state where the pallet fixture 2 is not attached to the pallet 10, the distance between the lower clamping part 30b and the fitting clamping part 25 is the thickness of the mounting deck portion 14 of the lower pallet 10c and the fitting It may be equal to or greater than the total thickness of the grounding deck portions 15 of the combined pallet 10a. At this time, the lower nip part 30b may have a shape that can press the mounting deck part 14 toward the fitting pallet 10a. For example, the lower stage clamping part 30b has a front end part that protrudes in the fork insertion direction from the fitting holding part 25, and a part other than the front end part of the lower stage clamping part 30b has a gap between the grounding deck part 15. And the shape of pressing the grounding deck portion 15 may be only the tip of the lower clamping portion 30b.

  In addition, the mounting deck part 14 is the back | inner side inclined surface which has the inclination which height becomes high gradually toward the back | inner side of a fork insertion direction like the grounding deck part 15 in the back | inner side in a fork insertion direction. You may have. At this time, it is preferable that the tip portion of the lower clamp portion 30b has a hook shape whose height is higher at a portion closer to the tip, like the tip portion of the upper clamp portion 30a described above. In the case of the lower holding part 30b having such a structure, the mounting deck part 14 is pressed against the fitting pallet 10a through contact between the lower holding part 30b inserted into the fork insertion port 13 and the rear inclined surface. Is possible. In addition, with such a configuration, the lower-stage clamping portion 30b inserted into the fork insertion port 13 by the engagement between the front end portion of the lower-stage clamping portion 30b and the back-side inclined surface of the mounting deck portion 14 has the fork difference. It is also possible to prevent the outlet 13 from coming out.

  The recess 34 is not limited to a shape having a certain depth along the fork insertion direction, but may be a shape having a different depth along the fork insertion direction. Any shape that dents in a direction away from the portion may be used. And the number of the recessed parts 34 which one 2nd clamping part has may be two or more. In addition, the recessed part 34 may be omitted in at least one of the upper stage clamping part 30a and the lower stage clamping part 30b.

  -The shape of the tip of the second clamping part such as the upper clamping part 30a or the lower clamping part 30b is not limited to the shape that narrows toward the distal end, and is, for example, a shape having a certain width toward the distal end. Alternatively, the shape may be thicker toward the tip. In short, the shape of the tip of the second clamping part is a shape that can be inserted into the fork insertion port 13, and the fitting clamping part 25 is fitted into the fork insertion port 13. Any shape may be used as long as the second deck portion is pressed in this state.

  The shape of the fitting sandwiching portion 25 is not limited to the shape that narrows toward the tip, but may be, for example, a shape that has a certain width toward the tip, or a shape that thickens toward the tip. May be. In short, the shape of the fitting sandwiching portion 25 may be any shape that can be fitted into the fork insertion port 13. Moreover, the shape which the front-end | tip part of the fitting clamping part 25 has is not restricted to the shape which has the chamfered corner | angular part, The shape which has the corner | angular part which is not chamfered may be sufficient.

  -The rib which supports the surrounding wall 22 which comprises a 2nd clamping part may have a shape extended in the direction orthogonal to the direction where the surrounding wall 22 is extended, and if it is the structure by which a some rib is provided. , They may have different shapes. It should be noted that such ribs may be omitted for the purpose of suppressing the amount of material used for forming the second sandwiching portion and suppressing the complexity of the structure of the second sandwiching portion.

  The shape of the reinforcing ribs 27 provided in the fitting sandwiching portion 25 is not limited to a triangular shape, and may be other shapes such as a rectangular plate shape or a linear shape, and surrounding walls facing each other in the fitting sandwiching portion 25 The shape which connects 22 may be sufficient.

  The position of the reinforcing rib 27 provided in the fitting / holding portion 25 is not limited to the position where the elongated hole 26 is sandwiched, and may be only one of the elongated holes 26 in the direction in which the elongated hole 26 extends, Regardless of the position, it may be the center or tip of the fitting and clamping part 25 in the fork insertion direction. In short, any position may be used as long as the mechanical strength of the fitting / clamping part 25 is increased when the fitting / clamping part 25 is fitted.

  The purpose of the reinforcing ribs 27 provided in the fitting / clamping part 25 is to reduce the amount of material used to form the fitting / clamping part 25 and to suppress the complexity of the structure of the fitting / clamping part 25. May be omitted.

  The fitting sandwiching portion 25 may be a simple solid rectangular parallelepiped shape or a box shape, and is not limited to a shape including a support wall and a sandwiching wall. Any structure can be used as long as the structure is fitted to 13. In addition, if the main structure of the fitting clamping part 25 is a structure which consists of a support wall and a clamping wall, as mentioned above, it can suppress the usage-amount of the material required for formation of the fitting clamping part 25, It is possible to reduce the weight of the pallet fixture 2.

  The long hole 26 provided in the fitting / clamping part 25 may have any shape that promotes elastic deformation of the fitting / clamping part 25 when the fitting / clamping part 25 is inserted into the fork insertion port 13. A circular hole or an elliptical hole may be used. Further, the long hole 26 may be omitted for the purpose of increasing the mechanical strength of the fitting and clamping part 25. In addition, if the long hole 26 provided in the fitting sandwiching portion 25 has a shape extending along the fork insertion direction, the elastic deformation of the fitting sandwiching portion 25 is promoted over a wide range in the fork insertion direction, and An excessive amount of deformation can be suppressed. Therefore, the shape of the long hole 26 extends along the fork insertion direction in order to achieve both the promotion of elastic deformation of the fitting and holding part 25 and the securing of the mechanical strength of the fitting and holding part 25. It is preferable that

  In the state where the pallet fixing tool 3 is attached to the pallet 10, the fitting / clamping part 25 may be positioned below the second clamping part 30, and the fitting / clamping part 25 is located above the second clamping part 30. If it is a form in which a plurality of pallet fixtures 3 are used, a combination thereof may be used.

The handle portion 35 may be omitted, and in such a configuration, the main body portion 23 is a target to be gripped.
The pallet to which the pallet fixtures 2 and 3 are attached may be a pallet having a fork insertion port and a deck portion that partitions the fork insertion port. For example, the pallet to which the pallet fixing tool of the present disclosure is attached may be a single-sided use type pallet in which the use surface is one side, or may be a double-sided use type pallet in which the use surface is double-sided.
