[0017] As shown in FIG. 1(a), the handle structure (3) for the box pallet of this embodiment is attached to a predetermined side wall panel (2) of a box pallet having four side wall panels connected so as to be square when viewed from the plane. The side wall panel (2) has a plurality of vertical members (21) along the vertical direction and a plurality of horizontal members (22) along the horizontal direction.

[0018] The handle structure (3) for the box pallet includes a handle body (4) and two holding members (5) attached to the upper left and upper right portions of the side wall panel (2) for holding the left and right end portions of the handle body (4).

[0019] The handle body (4) is made of a rod-shaped member with a circular short cross-section, and adjustment holes (41) formed to penetrate in the short direction (in this embodiment, the vertical direction) of the handle body (4) are arranged at a predetermined interval in the longitudinal direction (in this embodiment, the horizontal direction) of the handle body (4). Note that the handle body (4) is hollow, but is not limited thereto. The adjustment holes (41) may be arranged over the entire length of the handle body (4), or may be arranged only on both end portions excluding the central portion in the longitudinal direction of the handle body (4). Also, the short cross-section of the handle body (4) may be rectangular or other shapes.

[0020] Next, referring to FIG. 3, taking the holding member (5) attached to the upper right part of the side wall panel (2) as an example, the details of the holding member (5) will be described. Note that since the holding member (5) attached to the upper left part of the side wall panel (2) has a structure symmetric to the left and right with the holding member (5) attached to the upper right part of the side wall panel (2), the description thereof will be omitted.

[0021] The holding member (5) includes an attachment portion (6) for attaching the holding member (5) to the side wall panel (2), a U-shaped clamping portion (7) configured to sandwich the handle body (4) in the lateral direction (in this embodiment, the vertical direction) of the handle body (4), and a connecting portion (51) extending in the front-rear direction for connecting the attachment portion (6) and the U-shaped clamping portion (7).

[0022] The attachment portion (6) has a first plate member (61) disposed in front of the side wall panel (2) and abutting or adjacent to the front surface of the horizontal member (22) of the side wall panel (2), and a second plate member (62) disposed behind the side wall panel (2) and abutting or adjacent to the rear surface of the horizontal member (22) of the side wall panel (2). The first plate member (61) and the second plate member (62) are formed in a strip-shaped plate shape in front view that is narrower than the separation dimension between the vertical members (21) adjacent to each other in the left-right direction of the side wall panel (2), and are configured to be disposed facing each other while sandwiching the side wall panel (2) between the vertical members (21) adjacent to each other in the left-right direction of the side wall panel (2) in the state where the handle is completely attached.

[0023] The first plate (61) has a connecting portion (51) fixed perpendicularly to its front surface by fastening means such as welding. The upper part of the first plate (61) has a U-shaped locking portion that, when the handle is installed, embraces and locks a predetermined horizontal wire (22a) of the side wall panel (2). A forward-projecting reinforcing piece extends vertically from the left edge of the first plate (61). The lower part of the first plate (61) has a U-shaped notch cut out from the lower edge. Furthermore, when the handle is installed, the lower edge of the first plate (61) is positioned lower than the lower edge of another horizontal wire (22b) located below the horizontal wire (22a) to which the upper part of the first plate (61) is locked.

[0024] In detail, the first plate (61) has a first front plate portion positioned to abut or be close to a predetermined transverse wire (22a) and another transverse wire (22b) located below it from the front; a rear protruding plate portion formed horizontally protruding rearward from the upper edge of the first front plate portion; and a first rear plate portion formed hanging downward from the tip (rear end) of the rear protruding plate portion. The upper part of the first front plate portion, the rear protruding plate portion, and the first rear plate portion form a U-shaped locking portion.

[0025] A snap lock (64) is attached to the front surface of the first plate material (61). The snap lock (64) has a base portion fixed to the front surface of the first plate material (61), an operating portion (lever member) pivotally attached to the base portion so as to be able to swing up and down, and an engaging portion consisting of a ring-shaped hook that is pivotally attached to the operating portion. The structure for generating the retraction force (engaging force) of the snap lock (64) is flexible and can be a spring-loaded biasing member such as a torsion coil spring or a toggle mechanism. The snap lock (64) is also called a snap lock, toggle latch, or draw latch.

[0026] The second plate (62) is pivotably connected to the first rear plate portion of the first plate (61) via a hinge portion (63). The hinge portion (63) is made up of a hinge member. One end of the hinge member is fixed to the lower end of the first rear plate portion of the first plate (61), and the other end is fixed to the upper end of the second plate (62). The pivot axis of the hinge member is horizontal along the left-right direction.

[0027] The second plate (62) has an L-shaped hook portion at its lower end that is positioned to abut against or be close to the rear and lower sides of the other horizontal wire (22b) when the handle is attached, and a hook portion connected to the tip of the hook portion and positioned lower than the other horizontal wire (22b) when the handle is attached.

[0028] More specifically, the second plate (62) has a second rear plate portion positioned to abut or be close to the transverse wire (22a) and other transverse wires (22b) from the rear, a forward projecting piece portion formed horizontally protruding forward from the lower edge of the second rear plate portion when the handle is installed, and a hanging piece portion formed protruding downward from the tip of the forward projecting piece portion. An L-shaped hook portion is formed by the lower end of the second rear plate portion and the base end of the forward projecting piece portion. Furthermore, an inverted L-shaped hook portion is formed by the tip of the forward projecting piece portion and the hanging piece portion. When the handle is installed, the hook portion is positioned lower than the other transverse wires (22b) and is positioned to protrude forward from the notch of the first plate (61). When the handle is installed, the engaging portion of the latch (64) attached to the first plate (61) engages with the hook portion of the second plate (62), thereby connecting the lower part of the first plate (61) and the lower part of the second plate (62) and sandwiching the other horizontal wire (22b).

[0029] The first plate (61) is secured to a predetermined horizontal wire (22a) by a locking part, and the lower part of the first plate (61) and the lower part of the second plate (62) are connected by a snap lock (64) to sandwich another horizontal wire (22b), thereby attaching the mounting part (6) to the horizontal wire (22), and allowing the holding member (5) to be attached to the side panel (2). With the above configuration, the holding member (5) can be attached to any position on a grid-like side wall panel (2) having multiple vertical wires (21) and multiple horizontal wires (22). Furthermore, the box pallet to which the handle structure (3) is attached only needs to have at least one grid-like panel among the four side wall panels (2).

[0030] The U-shaped clamping portion (7) is U-shaped with a forward opening when viewed from the left and right, and has a strip-shaped upper plate portion (71) that is positioned to abut or be close to the upper side of the handle body (4) when the handle body (4) is being held, a strip-shaped intermediate plate portion (72) that is formed hanging down from the rear end of the upper plate portion (71), and a strip-shaped lower plate portion (73) that is formed to protrude forward from the lower end of the intermediate plate portion (72) and is positioned to abut or be close to the lower side of the handle body (4) when the handle body (4) is being held. The upper plate portion (71) and the lower plate portion (73) are positioned opposite each other. The rear surface of the intermediate plate portion (72) is fixed perpendicularly to the connecting portion (51) by a fixing means such as welding.

[0031] Fixing holes (8) are formed opposite each other at both ends of the U-shaped clamping portion (7), namely the upper plate portion (71) and the lower plate portion (73). The fixing holes (8) are arranged to communicate with the adjustment holes (41) of the handle body (4) when the handle body (4) is being held, and multiple fixing holes (2 in this embodiment) are formed in each of the upper plate portion (71) and the lower plate portion (73) at predetermined intervals in the left-right direction. Preferably, the distance between adjacent fixing holes (8) is set to be equal to the distance between adjacent adjustment holes (41). With the fixing holes (8) and adjustment holes (41) communicating, the handle body (4) and the holding member (5) are fixed using a fixing bracket (9) (in this embodiment, a bolt (91), a nut (92), a washer (93), and a round pipe (94)). By connecting any adjustment hole (41) to the fixing hole (8), the holding position of the retaining member (5) on the handle body (4) can be adjusted along the longitudinal direction of the handle body (4). Note that the fixing bracket (9) is not limited to the above, and can be changed as appropriate as long as it has the function of fixing the handle body (4) and the retaining member (5) by being inserted through the fixing hole (8) and the adjustment hole (41).

[0032] The handle structure (3) is attached to the side wall panel (2), and adjustments are made when attaching it to side wall panels (20) of different widths, as follows.

[0033] The handle structure (3) is attached to the side wall panel (2) in the following order: first, the retaining member (5), which does not hold the handle body (4), is attached to a predetermined location on the side wall panel (2) (in this embodiment, the upper left and upper right parts); and then the handle body (4) is attached to the retaining member (5).

[0034] In detail, first, the locking portion of the first plate (61) is attached to a predetermined horizontal wire (22a) from above and locked in place, so that the first plate (61) is positioned along the front surface of the side wall panel (2). Then, the second plate (62) is swung and positioned along the rear surface of the side wall panel (2), so that the hook portion of the second plate (62) protrudes forward from the notch of the first plate (61) below the other horizontal wires (22b). From this state, the engaging portion of the snap lock (64) is engaged with the hook portion of the second plate (62), and the operating portion is further swung to a position along the front surface of the first plate (61), thereby completing the attachment of the retaining member (5) to the side wall panel (2). The attachment point of the retaining member (5) to the side wall panel is set appropriately considering the width of the side wall panel, the length of the handle body (4), etc.

[0035] Next, the handle body (4) is attached to the left and right holding members (5). The handle body (4), which is in a horizontal position with its longitudinal direction as the left-right direction, is inserted from the front into the front opening of the U-shaped clamping portion (7) of the holding member (5), and the left-right position of the handle body (4) is adjusted so that the fixing hole (8) and the predetermined adjustment hole (41) are in communication. In this state, the bolt (91) and round pipe (94) are inserted into the fixing hole (8) and adjustment hole (41), and fastened with nuts (92) and washers (93), thereby completing the holding of the handle body (4) by the holding member (5).

[0036] When changing the holding position of the handle body (4) by the holding member (5), or when attaching the handle structure (3) to a narrow side wall panel (20), the holding member (5) is attached to the side wall panel (2)(20) without the handle body (4) being held. Then, the handle body (4) is positioned so that the fixing hole (8) and the adjustment hole (41) on the longitudinal center side of the handle body (4) are in communication, and the adjustment position of the handle body (4) by the holding member (5) is completed by fixing it with the fixing bracket (9) (see Figure 2).

[0037] As can be seen from the above, the box pallet handle structure (3) according to this invention is attached to a predetermined side wall panel (2) of a box pallet having four side wall panels connected so as to form a rectangle when viewed from above, and comprises a rod-shaped handle body (4) and a holding member (5) attached to the side wall panel (2) to hold the handle body (4), the handle body (4) includes adjustment holes (41) formed to penetrate in the short direction of the handle body (4) and arranged at predetermined intervals in the longitudinal direction of the handle body (4), and the holding member (5) holds the handle body (4) in the short direction of the handle body (4) The handle body (4) includes a U-shaped clamping portion (7) configured to clamp from the opposite direction, fixing holes (8) formed opposite each other at both ends of the U-shaped clamping portion and arranged to communicate with adjustment holes (41) when holding the handle body (4), and a fixing bracket (9) that is inserted through the communicating adjustment holes (41) and fixing holes (8) to fix the handle body (4) and the holding member (5). Two fixing holes (8) are formed at a predetermined interval in the longitudinal direction of the handle body (4) when holding the handle body (4), and the distance between adjacent adjustment holes (41) is equal to the distance between the two fixing holes (8). This configuration allows the handle body (4) to be stably attached to the holding member (5) with a simple configuration, the holding position of the handle body (4) by the holding member (5) can be easily adjusted in the longitudinal direction of the handle body (4), and furthermore, one handle structure can be attached to box pallets with different widths of side panels, thereby reducing manufacturing costs. Furthermore, this improves maneuverability when the user grips the handle to move the box pallet, and reduces the risk of damage to the handle structure.

[0038] In the above embodiment, the handle body (4) is positioned horizontally and the retaining member (5) is attached to the horizontal wire 22. However, the handle body (4) may be positioned vertically and the retaining member (5) may be attached to the vertical wire 21. In this case, for example, two handle structures (3) can be attached to the side wall panel (2) by attaching the vertically positioned handle body (4) to the retaining members (5) attached to the upper left and lower left parts of the side wall panel (2), and the vertically positioned handle body (4) to the retaining members (5) attached to the upper right and lower right parts of the side wall panel (2). Furthermore, when attaching a handle structure to a side wall panel with an extremely narrow width, for example, the handle structure can be attached by attaching one retaining member to the center of the side wall panel and then attaching the handle body. In this case, it is preferable that the adjustment hole is also located in the longitudinal center of the handle body.

[0039] Furthermore, it is preferable that circular caps are attached to both ends of the handle body (4) to close the openings, and that a handle cover is attached to the portion of the handle body (4) that is longitudinally towards the center from the holding position by the retaining member (5). This prevents the user from accidentally inserting their fingers into the openings or adjustment holes (41) at both ends of the handle body (4) and injuring themselves when gripping the handle body to perform tasks such as transporting.
