Description

  The present invention relates to a support used for transporting a workpiece or the like.

  Conventionally, when a work is placed on a base member such as a pallet to be transported or stored, a plurality of supports are attached to the base member in order to prevent the work from falling off or to be protected. There is a technique of supporting in a state where it is separated from the center (for example, see Patent Document 1).

Japanese Patent No. 4091375

  By the way, in the technique described in Patent Document 1, the support is attached to the base member using bolts and nuts. For this reason, a support tool and a base member need to be configured not only to correspond to each other's shape but also to a shape that allows bolts and nuts to be attached respectively. Under such circumstances, there are concerns that many restrictions may occur on the shape of the support and base member and the installation location of the support, and in some cases, the shape of the support and base member may be complicated. There is a risk of increasing the size of the support. Furthermore, there is a concern that the work for attaching the support tool takes time and increases the cost.

  The present invention has been made to solve the above-described problems and the like, and an object of the present invention is to provide a support tool capable of improving mounting workability while achieving compactness.

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

Means 1. A support that is attached to a mounted portion provided on a base member and can support a predetermined workpiece in a state of being separated from the base member in the attached state,
A main body portion in which a placement portion capable of supporting the lower surface of the workpiece on the upper surface side is formed, and a supported portion is formed on the lower surface side to be supported by the attached portion of the base member;
A mounting portion protruding downward from the main body portion,
The mounting portion includes an insertion piece that is inserted into an opening provided in the attached portion in a state where the supported portion is supported by the attached portion of the base member, and the insertion piece is an opening portion of the attached portion. In the state inserted in, the locking claw that is locked to the locked portion provided in the mounted portion,
The insertion pieces are provided in at least a pair, and are configured such that at least a pair of the insertion pieces can come into contact with the attached portion of the base member in the horizontal direction in a state where the engaging claw is engaged with the engaged portion. And at least one of the insertion pieces is configured to be elastically deformable,
The said locking claw is provided in the extending direction front end side of the insertion piece comprised at least among the said insertion pieces so that the said elastic deformation was possible, The support tool characterized by the above-mentioned.

  According to the means 1, since the attachment portion for attaching the support to the attachment portion of the base member protrudes downward from the main body portion (on the attachment direction side to the attachment portion), the base member is viewed in plan view. In this case, the installation space for the support can be made as small as possible. Further, in order to attach the support to the base member, it is not necessary to use separate attachment members such as bolts and nuts. As a result, it is possible to improve mounting workability, reduce costs, etc., and in the base member, it is no longer necessary to secure a space (for turning the wrench) for attaching bolts and nuts, It becomes relatively flexible with respect to the installation location of the support and the shapes of the base member and the support. Therefore, it is possible to install a support tool in a relatively narrow space of the base member, and it is possible to simplify and compact the shape of the base member and the support tool.

  Note that the workpiece and the base member may be made of metal, and the support may be made of resin. In addition, the “opening provided in the attached part” is intended to be a space (entrance) into which the insertion piece can be inserted, and not only the “hole” in which the outer edge is connected continuously, It is intended to include a “gap” between members (for example, a pair of wall portions) constituting the attached portion.

  Mean 2. The support tool according to means 1, further comprising a positioning portion that protrudes upward from the placement portion and can abut against the workpiece supported by the placement portion in the horizontal direction.

  According to the means 2, the workpiece placed on the placement portion can be positioned in the horizontal direction by the positioning portion, and the workpiece can be transported in a stable state. The positioning portion may be configured to be able to contact the outer edge portion of the work supported by the mounting portion, or may be configured to be inserted into a recess formed in the work and contact the inner surface thereof. .

  Moreover, it is good also as "the groove part is formed along the boundary part of the said mounting part and the said positioning part." In this case, it is possible to avoid a situation in which the support tool is scraped by the corner portion of the workpiece placed on the placement portion. Accordingly, it is possible to eliminate problems such as scraps adhering to the workpiece and unintentional damage to the support. Further, when the positioning portion is substantially L-shaped in plan view or substantially U-shaped in plan view (when it has a corner portion), a concave portion extending in the vertical direction is formed in the inner corner portion. It is good to be. In this case, when the workpiece is placed on the placement portion, it is possible to avoid a situation where the support tool is scraped off at the corner portion of the workpiece.

Means 3. The insertion piece is
A locking piece formed with the locking claw on the tip side;
A guide leg portion on which the locking claw is not formed,
The guide leg protrudes below the locking piece, and can contact the mounting portion of the base member in the horizontal direction when the locking claw is locked to the locked portion. 3. The support device according to means 1 or 2, wherein the support device is configured as described above.

  According to the means 3, the guide leg protrudes below the locking piece, and is inserted into the opening of the mounted portion prior to the locking piece when the support is mounted on the mounted portion. The Rukoto. Therefore, the locking piece can be inserted into the opening of the attached portion at a suitable relative position, and the support can be accurately attached, and the attachment workability can be improved. Further, the guide leg portion prevents the locking piece from coming into contact with the peripheral edge of the opening portion of the attached portion at an inappropriate angle during the mounting operation of the supporting device, or after the mounting of the supporting device. In contrast, when a horizontal external force is applied, the force applied to the locking piece can be reduced or not added, and the locking piece can be protected.

  In addition, it is good also as the guide leg part being provided in the both sides of the latching piece. In this case, even when a force is applied to the support tool in the horizontal direction in the mounting state of the support tool to the mounted part, the lock piece is deformed by the presence of the guide leg portions on both sides of the lock piece. The situation can be prevented. Accordingly, it is possible to prevent inadvertent dropping of the support tool and to stabilize the mounting state. In addition, since the displacement of the support tool in the horizontal direction is prevented by the guide leg portion, the locking piece can come into contact with the mounted portion when the locking claw is locked to the locked portion. You may be comprised so that it may not contact | abut.

Means 4. The supported portion and the locking claw are provided so as to protrude from the outer peripheral edge of the mounting portion to the outer peripheral side when the main body portion is viewed in plan view,
The body portion and the attachment portion are integrally formed by injection molding,
The support tool according to any one of means 1 to 3, wherein a notch portion is formed in the supported portion so that the supported portion does not exist at a position immediately above the locking claw. .

  According to the means 4, since the supported portion does not exist at a position directly above the locking claw, an undercut shape is formed between the upper surface (locking surface) of the locking claw and the lower surface of the supported portion. Such a situation can be avoided. Therefore, the support can be formed without preparing a separate slide core by the upper mold for forming the upper surface side of the main body and the lower mold for forming the lower surface of the main body.

  In addition, since the supported portion does not exist immediately above the locking claw, the force applied to the supported portion reaches the insertion piece having the locking claw when the workpiece is supported by the mounting portion. It is possible to suppress such a situation, and it is possible to suppress damage to the insertion piece. In addition, when providing a height difference between the placing portion and the supported portion, the main body portion is generally formed in a hollow shape. However, in this means, the supported portion and the locking claw are more than the placing portion. By projecting to the outer peripheral side, it is possible to avoid the upper surface side of the supported portion and the locking claw and the lower surface side of the mounting portion from being undercut, and the supported portion, the locking claw, and the mounting portion The upper surface and the lower surface can be reliably formed by the upper mold and the lower mold.

  Means 5. 5. The means according to claim 1, wherein the locking claw is formed in a taper shape such that a protruding length from the insertion piece gradually decreases toward a distal end in the extending direction of the insertion piece. Support tool.

  According to the means 5, it is possible to avoid a situation in which the locking claw is caught by the peripheral edge of the opening of the attached portion and is stretched when the support is attached to the attached portion. It can be inserted relatively smoothly into the opening of the part.

Is made up of. Furthermore, the pallet 2 of the present embodiment does not connect the frames 12 configured in units of the installation area 11 by welding or the like, but extends to a plurality of adjacent installation areas 11 and the first side 13 and the second side. 14 are assembled in a lattice shape (the second side portion 14 is on the upper side), and the first side portion 13 and the second side portion 14 are fixed by welding. However, the connection side 15 is fixed by welding for each installation region 11.

  In addition, a square frame-like pedestal frame 17 penetrating vertically is provided in the vicinity of both ends of the upper side portion of the connecting side portion 15. The pedestal frame 17 of the present embodiment is configured such that the widths of the side wall portions are the same, and adjacent side wall portions intersect each other at a right angle (in the shape of a square frame). Further, the inner diameter of the pedestal frame 17 is larger than the width of the connecting side part 15, and when the pallet 2 is viewed in plan (between the side surface of the connecting side part 15 and the inner surface of the pedestal frame 17 (support 3 described later). A gap is formed in which the locking piece 33 and the guide leg 32 can be inserted. In the present embodiment, the mounting portion is configured by the pedestal frame 17, and the support 3 is attached to each pedestal frame 17 as shown in FIG. Thus, the support 3 is installed.

  In addition, the lower side portion of the pedestal frame 17 is welded and fixed in contact with the upper surface of the connecting side portion 15. Further, the pallet 2 is provided with an auxiliary angle 19 adjacent to the first side 13 side of each pedestal frame 17. The auxiliary angle 19 is welded and fixed to the upper surface of the connecting side portion 15 and the inner side surface of the second side portion 14 and is also fixed to the outer surface of the base frame 17 by welding. The vertical width of the auxiliary angle 19 is longer than the vertical width of the pedestal frame 17 and protrudes upward from the pedestal frame 17.

  As shown in FIGS. 1 to 4, the support 3 is supported by the pedestal frame 17 of the pallet 2 and protrudes downward from the main body 21 and the main body 21 that can support the lower surface of the workpiece W. An attachment portion 31 is provided. The support 3 of the present embodiment is made of polypropylene and is integrally formed by injection molding.

  The main body 21 has a substantially square cylindrical body portion 22 that extends vertically and a square plate that is slightly smaller than the body portion 22, and the body portion 22 is configured to partially close the opening above the body portion 22. A mounting portion 23 that extends from two mutually orthogonal sides of the upper portion of the upper portion to the inner peripheral side of the barrel portion 22, two sides of the mounting portion 23 that are not connected to the barrel portion 22, and the upper side of the barrel portion 22 The positioning part 24 which connects between the parts and protrudes upwards rather than the mounting part 23, and the collar part 25 as a to-be-supported part extended from the lower side part of the trunk | drum 22 to an outer peripheral side are provided. In the present embodiment, as shown in FIGS. 8, 11, etc., the support 3 is supported by the pedestal frame 17 by the lower surface of the flange portion 25 coming into contact with the upper side of the pedestal frame 17. Yes. Further, as shown in FIGS. 5, 9, etc., the lower surface of one corner portion of the workpiece W is in contact with and supported by the upper surface of the placement portion 23.

  As shown in FIGS. 2, 8, and the like, the positioning portion 24 has a substantially L shape in plan view and is configured to be able to contact the corner portion of the outer peripheral surface of the work W supported by the placement portion 23 ( (See FIG. 9 etc.) The positioning portion 24 has an inner wall portion 24a and an outer wall portion 24b that are opposed to each other in the outer circumferential direction of the placement portion 23, and the lower portion of the inner wall portion 24a and the outer wall portion 24b are substantially in the vertical direction (with respect to the placement portion 23). In the inner wall portion 24a, a portion slightly lower than the central portion in the vertical direction is inclined upward toward the outer peripheral side of the mounting portion 23 while being curved upward. (See FIG. 10 etc.). That is, the upper portion of the inner wall portion 24 a of the positioning portion 24 is configured as a guide portion that guides the workpiece W to the placement portion 23 when the workpiece W is placed on the pallet 2. On the other hand, since the lower part of the inner wall portion 24a is erected vertically with respect to the placement portion 23, the displacement of the workpiece W placed on the placement portion 23 in the horizontal direction can be more reliably prevented. Can do.

  Further, as shown in FIGS. 2, 10, and the like, a groove portion 26 is formed in the mounting portion 23 along a boundary portion with the positioning portion 24. For this reason, when the workpiece W placed on the placement portion 23 is slid in the horizontal direction within the range of the inner peripheral side of the positioning portion 24 of the four support members 3, The boundary portion between the placement portion 23 and the positioning portion 24 can be prevented from being scraped. Furthermore, a concave portion 27 that extends vertically along the bent portion is formed in the corner portion on the inner side (recessed angle side) of the positioning portion 24 that has a substantially L shape in plan view. For this reason, when the workpiece W is placed on the placement portion 23, the corner portion of the positioning portion 24 is scraped by the corner portion of the workpiece W (the lower end portion of the corner portion of the outer peripheral surface of the workpiece W). Can be avoided.

  As shown in FIGS. 10, 11, etc., the outer size of the trunk portion 22 is substantially the same as the inner dimension of the pedestal frame 17, and if the flange portion 25 slightly protrudes from the trunk portion 22, the lower surface of the flange portion 25. Is caught on (supported against) the upper surface of the pedestal frame 17. In this embodiment, the collar part 25 protrudes from all four surfaces which comprise the outer peripheral surface of the trunk | drum 22, and the protrusion length from the trunk | drum 22 of the collar part 25 is the base frame 17 (wall part which comprises). It is almost the same as the thickness. For this reason, as shown in FIG. 11, the collar part 25 can be suitably contacted | supported also to the site | part with which the auxiliary | assistant angle 19 was adjacent among the base frames 17. As shown in FIG.

  In order to reinforce the flange portion 25, triangular ribs 28 having a triangular shape in side view are provided to connect the upper surface of the flange portion 25 and the side surface of the body portion 22. In particular, in a portion corresponding to the positioning portion 24, as shown in FIG. 3, the triangular rib 28 is formed to extend to the outer wall portion 24 b of the positioning portion 24 so that the positioning portion 24 is reinforced.

  As shown in FIGS. 1, 3, 4, and the like, the attachment portion 31 includes a guide leg portion 32 having a substantially L-shaped cross section extending downward from each corner portion of the lower side portion of the trunk portion 22, and a trunk portion. 22 is provided with a pair of locking pieces 33 extending downward from each of the intermediate positions in the longitudinal direction of the two opposite sides of the lower side portion of 22. As shown in FIGS. 8 and 10, the guide leg portion 32 and the locking piece 33 are inserted into the space on the inner peripheral side of the pedestal frame 17 in a state where the flange portion 25 is supported by the pedestal frame 17. It becomes. In the present embodiment, the guide leg 32 and the locking piece 33 constitute an insertion piece.

  Further, the guide leg portion 32 extends below the locking piece 33. For this reason, when the attachment portion 31 is attached to the pedestal frame 17, the guide leg portion 32 is inserted into the pedestal frame 17 prior to the locking piece 33. Furthermore, as described above, since the outer dimension of the trunk portion 22 is substantially the same as the inner dimension of the pedestal frame 17, the guide leg portion 32 and the locking piece 33 extending downward from the lower side portion of the trunk portion 22 are The outer surface is substantially in contact with the inner surface of the pedestal frame 17. Thereby, the position shift in the horizontal direction of the support tool 3 is prevented.

  The locking piece 33 is configured to be elastically deformable in the outer peripheral direction of the main body portion 21 and includes a locking claw 34 that protrudes from the lower end portion to the outer peripheral side of the main body portion 21. As shown in FIG. 10 and the like, the distance between the upper surface (locking surface) of the locking claw 34 and the lower surface of the flange portion 25 in the vertical direction is substantially the same as the vertical width of the base frame 17 (slightly larger). When the locking piece 33 is inserted into the pedestal frame 17 and the flange 25 is brought into contact with the upper side of the pedestal frame 17, the locking claw 34 is locked to the lower side of the pedestal frame 17. It is like that. Further, the locking pieces 33 are provided as a pair so as to face each other, and the locking claw 34 of each locking piece 33 is locked to the lower side portion of the pedestal frame 17. Displacement in the direction of removal from the pedestal frame 17 is restricted, and falling off is prevented.

  Further, the locking claw 34 is formed in a taper shape in which the protruding length from the locking piece 33 gradually decreases toward the distal end (downward) of the locking piece 33 in the extending direction. For this reason, the lower surface of the locking claw 34, that is, the surface that comes into contact with the upper side of the pedestal frame 17 when the locking piece 33 is inserted into the pedestal frame 17, is in the insertion direction (attachment direction). It is designed to extend diagonally. Further, as shown in FIGS. 4 and 10, an auxiliary rib 35 extending vertically is formed on the inner surface side of the locking piece 33 at the base side portion of the central portion in the width direction. In addition, corresponding to the side portion where the locking piece 33 is not provided in the lower side portion of the body portion 22, the upper portions of the guide leg portions 32 facing each other in the longitudinal direction of the side portion are connected. A provided reinforcing wall portion 36 is provided. Also, reinforcing ribs 29 are provided inside the main body portion 21 and the reinforcing wall portion 36 so as to connect the opposing wall portions (see FIG. 4 and the like).

  Further, as shown in FIG. 3 and the like, the flange portion 25 is notched so that the flange portion 25 does not exist at a portion corresponding to the locking piece 33, that is, at a position immediately above the locking claw 34. A notch 38 is formed. For this reason, in the said site | part, the outer surface of the latching piece 33 and the outer surface of the trunk | drum 22 are extended continuously (it is flush | level). Further, on the outer surface of the guide leg portion 32 and the reinforcing wall portion 36, the outer peripheral surface of the mounting portion 31 (the outer surface of the guide leg portion 32 and the reinforcing wall portion 36) and the pedestal when the support 3 is attached to the pedestal frame 17. An inclined rib 39 is provided to fill a gap between the inner surface of the frame 17 and suppress backlash. The inclined rib 39 gradually protrudes upward from the guide leg portion 32 and the reinforcing wall portion 36, and the upper end portion is connected to a portion on the projecting direction root side with the body portion 22 on the lower surface of the flange portion 25. Has been. In addition, the boundary part of the lower surface of the collar part 25 and the outer peripheral surface (the outer surface of the guide leg part 32 or the reinforcement wall part 36) of the attaching part 31 is formed in the curved shape instead of a right angle on account of shaping | molding. Become. The maximum protruding length of the inclined rib 39 corresponds to the formation width of the curved portion, and the inclined rib 39 prevents the upper side portion of the pedestal frame 17 from coming into contact with the curved portion. ing.

  In the present embodiment, the lower side portion of the pedestal frame 17 to which the locking claw 34 is locked constitutes the locked portion of the mounted portion. Further, in this embodiment, when the locking piece 33 is inserted into the pedestal frame 17, the locking piece 33 is appropriately elastically deformed. However, when the locking claw 34 protrudes below the pedestal frame 17, The elastic claw 34 returns to a straight extension state, and the locking claw 34 is locked to the lower side of the pedestal frame 17, and the side surface of the locking piece 33 substantially contacts the inner side surface of the pedestal frame 17. It will be in contact. Further, since there is a gap between the inner side surface of the pedestal frame 17 and the side side portion of the connecting side portion 15, the locking piece 33 and the guide leg portion 32 are inserted through the pedestal frame 17 and can be attached. However, in the mounting state of the support tool 3, the guide leg 32 is brought into a substantially abutting state also on the side surface of the connecting side part 15, so that the mounting state is stabilized and the mounting state of the support tool 3 is changed. When the latching piece 33 is elastically deformed to some extent to release, the latching piece 33 abuts against the side surface of the connecting side portion 15 and the latching piece 33 is prevented from being deformed more than necessary. Damage can be prevented.

  Furthermore, as described above, the auxiliary angle 19 is provided adjacent to the pedestal frame 17, and in the present embodiment, the pedestal frame 17 provided to protrude laterally from the connecting side part 15, and the second side part 14 are arranged close to each other. For this reason, even when the support 3 attached to the pedestal frame 17 tries to tilt toward the outer peripheral side of the installation region 11, the outer surface side of the positioning portion 24 abuts on the auxiliary angle 19 and the second side portion 14, Such tilt displacement is regulated. Therefore, damage to the support 3 can be suppressed.

  As described above in detail, according to the present embodiment, the attachment portion 31 for attaching the support 3 to the pedestal frame 17 of the pallet 2 projects downward from the main body portion 21 (on the attachment direction side to the pedestal frame 17). It is installed. For this reason, the installation space of the support tool 3 when the pallet 2 is viewed in plan can be made as small as possible. Further, in order to attach the support 3 to the pallet 2, it is not necessary to use separate attachment members such as bolts and nuts. As a result, it is possible to improve the mounting workability, reduce the cost, etc., and in the pallet 2, there is no need to secure a space (for turning the wrench) for mounting the bolts and nuts. The installation place of the support tool 3 and the shapes of the pallet 2 and the support tool 3 become relatively flexible. Therefore, it is possible to install the support 3 in a relatively narrow place of the pallet 2 and to simplify the shape and compactness of the pallet 2 and the support 3.

  The support 3 includes a positioning portion 24 that protrudes upward from the placement portion 23 and can abut against the workpiece W supported by the placement portion 23 in the horizontal direction. For this reason, the workpiece W placed on the placement portion 23 can be positioned in the horizontal direction by the positioning portion 24, and the workpiece W can be transported in a stable state.

  Further, the guide leg portion 32 protrudes downward from the locking piece 33 and is inserted into the pedestal frame 17 prior to the locking piece 33 when the support 3 is attached to the pedestal frame 17. It becomes. Therefore, the locking piece 33 can be inserted into the pedestal frame 17 at a suitable relative position, so that the support 3 can be accurately attached and the attachment workability can be improved. Further, the guide leg portion 32 prevents the locking piece 33 from coming into contact with the upper side portion of the pedestal frame 17 at an inappropriate angle during the mounting operation of the support tool 3, and supports the support tool 3 after mounting the support tool 3. When an external force in the horizontal direction is applied to the tool 3, the force applied to the locking piece 33 can be reduced or prevented from being added, and the locking piece 33 can be protected. In particular, in this embodiment, since the guide leg portions 32 are provided on both sides of the locking piece 33, a force is applied to the support tool 3 in the horizontal direction when the support tool 3 is attached to the base frame 17. Even if it adds, the situation where the latching piece 33 deform | transforms by presence of the guide leg part 32 of the both sides of the latching piece 33 can be prevented. Therefore, careless removal of the support 3 can be prevented, and the attachment state can be stabilized.

  Further, a notch portion 38 is formed in the flange portion 25 so that the flange portion 25 does not exist at a position immediately above the locking claw 34. For this reason, the situation where the space between the upper surface (locking surface) of the locking claw 34 and the lower surface of the flange 25 becomes an undercut shape can be avoided. Therefore, the support 3 can be molded without preparing a separate slide core by the upper mold that molds the upper surface side of the main body 21 and the lower mold that forms the lower surface side of the main body 21. Further, since the flange portion 25 does not exist immediately above the locking claw 34, the force applied to the flange portion 25 reaches the locking piece 33 in a state where the workpiece W is supported by the placement portion 23. Such a situation can be suppressed, and damage to the locking piece 33 can be suppressed.

  In addition, the locking claw 34 is formed in a taper shape in which the protruding length from the locking piece 33 gradually decreases toward the lower side which is the front end side of the locking piece 33 in the extending direction. Therefore, when the support 3 is attached to the pedestal frame 17, it is possible to avoid a situation in which the locking claw 34 is caught by the upper side portion of the pedestal frame 17 and is pulled, and the mounting portion 31 including the locking claw 34. Can be inserted into the pedestal frame 17 relatively smoothly.

  Further, a groove portion 26 is formed in the mounting portion 23 along a boundary portion with the positioning portion 24. For this reason, the situation where the support tool 3 is shaved by the corner | angular part of the workpiece | work W mounted in the mounting part 23 can be avoided. Further, a concave portion 27 extending in the vertical direction is formed at a corner portion inside the positioning portion 24. For this reason, when mounting the workpiece | work W on the mounting part 23, the situation where the support tool 3 will be shaved by the corner | angular part of the workpiece | work W can be avoided. With these configurations, it is possible to eliminate problems such as scraps adhering to the workpiece W and unintended damage to the support 3.

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

  (A) In the said embodiment, the shape of the support tool 3 is not specifically limited, The main-body part 21 which comprises the mounting part 23 which supports the workpiece | work W, and the collar part 25 supported by the base frame 17 is provided.

  For example, as shown in FIG. 12, the positioning unit 24 may be omitted. The support tool 3 without the positioning part 24 can be used in combination with the support tool 3 including the positioning part 24 to prevent the displacement of the workpiece W in the horizontal direction as in the above embodiment. That is, even if all the support tools 3 do not have the positioning portions 24, for example, if the diagonal support tools 3 include the positioning portions 24 having a substantially L shape in plan view, the other support tools 3 have the positioning portions 24. Even without 24, it is possible to prevent the displacement of the workpiece W in the horizontal direction.

  (B) In the above embodiment, the square tube-shaped pedestal frame 17 is fixed to the pallet 2 to constitute the attached portion to which the support 3 is attached. However, the embodiment is not particularly limited to such a configuration. However, it is only necessary to be configured so that the movement of the support 3 in the horizontal direction and the removal direction can be restricted. For example, as shown in FIG. 12, a part of the pedestal frame 17 may be cut out, or the pedestal frame 17 may be configured by a plurality of parts (two parts having a U-shaped cross section in FIG. 12). Further, for example, an opening that penetrates up and down with respect to the connecting side 15 may be formed, and the attachment 31 of the support 3 may be inserted and attached to the opening. Further, the auxiliary angle 19 may be omitted. In the above embodiment, the pedestal frame 17 is fixed by welding to the auxiliary angle 19 or the like, but may be fixed using bolts and nuts.

Further, the support 3 may be configured to change the attachment position in plan view and the height position of the placement portion 23 in accordance with the shape of the work W to be placed. In this case, with respect to the mounting position in plan view, the position of the pedestal frame 17 as the mounted portion is changed. However, when changing the height position of the mounting portion 23, the mounting position of the pedestal frame 17 is changed. In addition to changing, it is also possible to cope by changing the thickness of the main body 21 of the support 3.

  (D) Moreover, the shape of the positioning part 24 is not specifically limited, For example, one side part of the mounting part 23, or a substantially I shape in planar view along three side parts, Or you may comprise in planar view substantially U shape. Furthermore, instead of being configured in a wall shape along the side portion of the mounting portion 23, it may be configured in a protruding shape (pin shape or the like), or support the mounting portion 23 (the lower surface of the workpiece W). It may be configured to be inserted into a concave portion (or a hole or a gap) formed on the lower surface side of the work W and to be in contact with the inner side surface of the portion at the inner peripheral side of the outer peripheral edge.

  Moreover, in the said embodiment, although the base frame 17 is contact | abutting with the connection side part 15, you may fix in the state which floated the base frame 17 from the connection side part 15. FIG. In this case, it is possible to select the mounting direction of the support 3 including the positioning unit 24 such as an I-type in a plan view. In addition, in the said embodiment, although the site | part of the upper side of the inner wall part 24a of the positioning part 24 inclines and extends in the outer peripheral side of the mounting part 23, it becomes a structure which functions as a guide of the workpiece | work W. The inner wall portion 24a may extend vertically from the top to the bottom with respect to the placement portion 23.

  (E) In the above embodiment, the support tool 3 is provided so as to be able to support the four corners of the lower surface of the workpiece W. However, the present invention is not particularly limited to such a configuration, and a plurality of support tools 3 are used. Thus, it is sufficient that the workpiece W is supported so as not to touch the pallet 2 and can be prevented from being displaced in the horizontal direction. For example, using the support 3 without the positioning part 24 described in (a) above or the support 3 provided with the positioning part 24 having a substantially I-shape in plan view described in (d) above, You may comprise so that the center part vicinity of each side part can be supported. Further, the workpiece W is not supported by the four support tools 3, but may be supported by, for example, five or more support tools 3, or three support tools 3 (for example, one corner portion of the workpiece W). And the central part of the two side parts).

  (F) Further, in the above embodiment, the support 3 is integrally formed by injection molding, but may be configured by assembling a plurality of parts. For example, the positioning unit 24 may be configured separately from the main body unit 21 (configured to be detachable). Further, for example, a cushioning member made of rubber or the like may be laid on the upper surface of the placement portion 23.

  (G) In the said embodiment, although the support tool 3 is comprised with the polypropylene, you may comprise with another raw material. For example, you may comprise with other resin materials, such as polyethylene, PET, and polyamide. Moreover, in the said embodiment, although the workpiece | work W and the pallet 2 are comprised with the metal (iron), a constituent material in particular is not limited, For example, the product made from resin and wooden may be sufficient as the pallet 2. And it is good also as being used for conveyance etc. of resin work W. In addition, in order to carry the heavy and fragile work W, when the pallet 2 is made of metal and the strength is increased, the support tool 3 is used so that the support tool 3 also functions as a cushioning material. Since the malfunction resulting from contact with the workpiece | work W can be avoided, the effect by using the support tool 3 will be exhibited further.

  (H) In the above embodiment, the guide leg portions 32 are provided so as to extend downward from the respective corner portions of the lower side portion of the trunk portion 22, but the number and positions of the guide leg portions 32 are not particularly limited. It is not limited, and it is only necessary to be configured to be able to contact the inner surface of the pedestal frame 17 when the support 3 is attached. However, in order to improve the guide effect, it is desirable to provide a pair at least at opposing positions, and it is more desirable to provide them on both sides of each locking piece 33 in order to protect the locking pieces 33. In addition, since three or more guide leg portions 32 are provided at the same position, the guide effect and the positional deviation prevention effect are further enhanced, and the support 3 alone can be stored relatively stably in an upright state. it can.

  In addition, all the guide legs 32 can be omitted. In this case, the pair of locking pieces 33 are substantially attached to the inner surface of the pedestal frame 17 in a state in which the supporting tool 3 is attached to the pedestal frame 17 in order to prevent the displacement of the support 3 in the horizontal direction by the locking pieces 33. It shall be comprised so that it may contact | abut. When the guide leg portion 32 is provided and the movement of the support 3 in the horizontal direction is restricted by the guide leg portion 32, the locking claw 34 provided at the distal end portion of the locking piece 33 is a base frame. As long as it can be locked to 17, the locking piece 33 itself may be configured not to contact the pedestal frame 17.

  (I) In the embodiment described above, the locking claw 34 is configured to be locked to the lower side portion of the pedestal frame 17, but a horizontal hole is formed in the pedestal frame 17 and the locking claw 34 is formed in the horizontal hole. It is also possible to configure so that the locking claw 34 is locked to the peripheral edge thereof. From the standpoint that the support 3 can be removed from the pedestal frame 17 relatively easily or the pedestal frame 17 is simplified, the locking claw 34 is locked to the lower side of the pedestal frame 17. A configuration is preferred. On the other hand, from the viewpoint of making it difficult for the support 3 to be inadvertently detached from the pedestal frame 17, it is inserted into the lateral hole as described above so as to make it difficult to touch the locking claw 34, or the locking claw can be viewed from the side. It is more preferable to have a configuration in which the portion 34 is locked in the recess so that the portion 34 cannot be visually recognized. In the above embodiment, the lateral width of the locking piece 33 and the lateral width of the locking claw 34 may be the same or different.

  (J) In the above embodiment, the flange portion 25 is interrupted at the upper position of the locking piece 33, but it may be configured to extend from the entire peripheral region of the trunk portion 22. Moreover, in the said embodiment, you may interrupt the collar part 25 besides the site | part corresponding to the locking piece 33. FIG.

  Furthermore, in the said embodiment, in order to make desired height difference between the mounting part 23 and the collar part 25, the trunk | drum 22 is interposed between the mounting part 23 and the collar part 25, but the height is low. When it is not necessary to provide a difference, both the placing portion and the collar portion may be configured by a single plate-like body. However, when the configuration is adopted, the reinforcing rib (triangular rib 28) cannot be formed above the flange portion 25, so that the flange portion 25 is placed on the placement portion 23 as in the above embodiment. It is desirable to form at a position one step lower than that.
