Summary of the Invention

Problems to be Solved by the Invention

[0004] However, in the case of the box pallets described above, for example, from the perspective of transportation efficiency when loaded onto trucks and space saving when stored in warehouses, stores, etc., handle members that protrude outward from the side wall panels are avoided so that multiple box pallets can be lined up without gaps. Therefore, when users move the box pallets, they operate them by gripping the frame members, etc. Also, even when handle members are attached, they are attached so as not to protrude outward from the side wall panels. In the above configuration, when a load is placed on the box pallet, the user's fingers are inserted into the box pallet during operation, so there is a risk of injury if the fingers are caught between the load and the gripping part. Also, even when there is no load, if the user is gripping the frame members, there is a risk of injury if the fingers are caught between the frame members of other box pallets placed adjacent to it and the frame members being gripped. Furthermore, it is not good in terms of operability, and there was a problem of decreased work efficiency.

[0016] Hereinafter, embodiments of this invention will be described with reference to the drawings. In the following description, the up and down in Figures 1, 5, and 8 are referred to as "up and down", the left and right are referred to as "front and back", the front side is referred to as "left", and the back side is referred to as "right". Also, the left and right in Figures 2, 6, and 9 are referred to as "left and right", the up is referred to as "back", and the down is referred to as "front". However, the reference to the directions of components and the like based on the directions on these drawings is for convenience and does not limit the scope of the present invention. Also, the terms "horizontal" and "vertical" shall include angles slightly inclined from the horizontal and vertical. The shapes of the components described in this embodiment, their relative arrangements, etc. are not intended to limit the scope of the present invention as long as there is no specific description, and are merely illustrative examples.

[0017] Figures 1 to 4 show a handle structure (4) according to a first embodiment of the present invention. The handle structure (4) for a box pallet in this embodiment has a rectangular bottom (2) when viewed from the plane, and side wall panels (3) erected on each of the three sides of the bottom (2). The side wall panel (3) includes long frame members (31) that form both side edges of the side wall panel (3) and are respectively erected on adjacent corner portions of the bottom (4), and cross members (32) spanned between both frame members (31). It is attached to a predetermined side surface of the box pallet (1).

[0018] The bottom (2) has a bottom frame (21) to which casters are attached and a rectangular load-carrying plate (22) arranged on the bottom frame (21) when viewed from the plane. The load-carrying plate (22) may be detachable from the bottom frame (21) or may be swingably connected about the rear edge portion as an axis.

[0019] Side wall panels (3) are erected on three sides of the bottom frame (21). By the three side wall panels (3), the box pallet (1) has an opening for loading and unloading goods at the front, and the storage space for goods is surrounded. The lower parts of the left side wall panel (3L) and the rear side wall panel (3B) are fixed by bolts or welding. The right side wall panel (3R) is swingably connected to the rear side wall panel (3B). In the state where the goods are unloaded, by raising the load-carrying plate (22) along the rear side wall panel (3B), the right side wall panel (3R) can be swung along the rear side wall panel (3B). With this configuration, the unused box pallet (1) can be folded, and the storage space can be reduced. Also, the bottom frame (21) can be constituted by the lower end portions of the side wall panels (3). In this case, the bottom frame (21) has a front-opening U-shape when viewed from the plane.

[0020] The side wall panel (3) includes long frame members (31) that form both side edges of the side wall panel (3) and are erected vertically along adjacent corners of the bottom (2), and horizontal members (32) that span between the two frame members (31) along the left-right or front-back direction. In this embodiment, both frame members (31) are made up of both ends of an inverted U-shaped member formed by bending a single round pipe. The central part of the inverted U-shaped member connects both frame members (31) and forms the upper edge of the side wall panel (3). The horizontal members (32) are made of strip-shaped members and are spanned between the two frame members (31) at predetermined intervals (three in this embodiment). It is also preferable that multiple vertical members (four in this embodiment) are arranged at predetermined intervals along the vertical direction, so that the side wall panel (3) is in a grid shape. The bottom (2) and side wall panels (3) having the above configuration constitute a box pallet (1) of a type known as a roll box pallet.

[0021] The handle structure (4) comprises a U-shaped handle body (5) formed by bending a round pipe, a first fitting (6) fixed to one end (51) of the handle body (5) and detachably attached to a predetermined frame member (31), and a second fitting (7) fixed to the other end (52) of the handle body (5) and detachably attached to a frame member (31) located in a corner adjacent to the corner where the predetermined frame member (31) is located. In this embodiment, the handle body (5) is positioned along the left side wall panel (3L), the first fitting (6) is attached to the left side frame member (31BL) of the rear side wall panel (3B), and the second fitting (7) is attached to the front side frame member (31LF) of the left side wall panel (3L). This will be used as an example for explanation. The handle structure (4) can be attached to the left side wall panel (3L) and the right side wall panel (3R) of the box pallet (1) via the rear side wall panel (3B).

[0022] The first fitting (6) includes a plate-shaped outer plate portion (61) to which one end (51) of the handle body (5) is fixed perpendicularly by fastening means such as welding, and which is positioned to abut or approach the box pallet (1) from the outside (left side in this embodiment) of the frame material (31BL), a plate-shaped inner plate portion (62) positioned opposite the outer plate portion (61) and configured to abut or approach the box pallet (1) from the inside (right side in this embodiment) of the frame material (31BL), and a plate-shaped intermediate plate portion (64) connecting the outer plate portion (61) and the inner plate portion (62). The front-to-back lengths of the outer plate portion (61) and the inner plate portion (62) are configured to be equal. The first fitting (6) is U-shaped or U-shaped (U-shaped in this embodiment) when viewed from a plane that opens toward the second fitting (7) (facing forward in this embodiment). The first fitting (6) is configured such that the frame member (31) can pass between the ends of the outer plate portion (61) and the inner plate portion (62) from the short side of the frame member (31), and the frame member (31) is enclosed in the region formed by the outer plate portion (61), the intermediate plate portion (64), and the inner plate portion (62) from the short side of the frame member (31). In this embodiment, the first fitting (6) is formed by bending a single plate material, but it is not limited to this, and may be formed by joining separate plate materials by welding or the like.

[0023] The tip of the inner plate portion (62) has a U-shaped notch (63) cut out from the tip edge, and the horizontal member (32B) of the rear wall panel (3B) is configured to pass between the upper and lower edges of the notch (63). With this configuration, when the first fitting (6) is attached to the frame member (31BL), the upper edge of the notch (63) abuts against the upper edge of the horizontal member (32B), restricting the first fitting (6) from moving downward relative to the frame member (31BL), and the lower edge of the notch (63) abuts against the lower edge of the horizontal member (32B), restricting the first fitting (6) from moving upward relative to the frame member (31BL), so the notch (63) functions as a restricting portion (10) that restricts the vertical movement of the first fitting (6). Furthermore, it is preferable that the first fitting (6), the frame member (31), and the horizontal member (32) are configured such that, when the first fitting (6) is attached to the frame member (31), the first fitting (6) can swing freely at a slight angle around the frame member (31) as its axis.

[0024] The second fitting (7) includes a first plate (71) fixed to the other end (52) of the handle body (5), and a second plate (73) positioned opposite the first plate, with one end of the second plate (73) pivotably connected to one end of the first plate (71) via a hinge portion (8), and the first plate (71) and the second plate (73) working together to surround the frame member (31) from the short side direction. The first plate (71) and the second plate (73) are attached to the frame (31) by engaging the engaging portion (91) of the latch (9) attached to one of the first plate (71) and the second plate (73) (in this embodiment, the first plate (71)) with the hook portion (79) provided on the other of the first plate (71) and the second plate (73) (in this embodiment, the second plate (73)).

[0025] In detail, the first plate (71) is a plate-shaped member positioned on the outside of the box pallet (1) (in this embodiment, from the left side) so as to abut or approach the front frame member (31LF) of the left side wall panel (3L), and the other end (52) of the handle body (5) is fixed perpendicularly to the vertical center of its left side by fastening means such as welding. A reinforcing piece projecting to the left extends vertically from the front edge of the first plate (71).

[0026] A snap lock (9) is attached to the upper and lower parts of the left side of the first plate (71), sandwiching the other end (52) of the handle body (5). The snap lock (9) has a base part fixed to the left side of the first plate (71), an operating part (lever member) pivotally attached to the base part so as to be able to swing up and down, and an engaging part (91) consisting of a ring-shaped hook that is able to swing up and down attached to the operating part. The structure for generating the retraction force (engaging force) of the snap lock (9) is flexible and can be a spring-loaded biasing member such as a torsion coil spring or a toggle mechanism. The snap lock (9) is also called a snap lock, toggle latch, or draw latch. Only one snap lock (9) may be attached to the first plate (71).

[0027] The second plate (73) is a U-shaped or U-shaped plate member when viewed from above, and includes a central wall portion (74) which is positioned opposite the first plate (71) when the handle structure (4) is attached to the box pallet (1), and a front protruding wall portion (75) and a rear protruding wall portion (76) which are formed to protrude toward the first plate (71) (to the left in this embodiment) from the front and rear edges of the central wall portion (74). The second plate (73) is pivotably connected to the front end of the first plate (71) via a hinge portion (8). The hinge portion (8) is made up of a hinge member, one of which is fixed to the front end of the first plate (71), and the other of which is fixed to the tip of the front protruding wall portion (75) of the second plate (73). The pivot axis of the hinge member is vertical along the vertical direction. This configuration allows the first plate (71) and the second plate (73) to work together to surround the frame member (31LF) from the short side and to open it. Preferably, the rear end of the first plate (71) and the tip of the rear projection wall portion (76) of the second plate (73) are configured to abut against each other when the first plate (71) and the second plate (73) surround the frame member (31LF). In addition, two rear projection pieces (77) are formed at the top and bottom of the tip edge of the rear projection wall portion (76) of the second plate (73). The rear end of the rear projection wall portion (76) and the rear projection pieces (77) form an L-shaped hook portion (79) when viewed from above, and are configured to engage with the engaging portion (91) of the snap lock (9).

[0028] Restricting pieces (72) are formed projecting from the upper and lower rear edges of the first plate material (71) toward the second plate material (73) (to the right in this embodiment). The regulating pieces (72) are configured such that the horizontal member (32L) is inserted between the lower edge of the upper regulating piece (72) and the upper edge of the lower regulating piece (72). Preferably, the regulating pieces (72) are configured to follow the rear surface of the rear protruding wall portion (76) of the second plate material (73). Furthermore, a notch (78) is formed in the vertical center of the tip of the rear protruding wall portion (76) of the second plate material (73), cut out in a U-shape from the tip edge, and the horizontal member (32L) is configured to be inserted between the upper and lower edges of the notch (78). In other words, with the first plate (71) and the second plate (73) surrounding the frame member (31LF), an opening is formed by the upper and lower restricting pieces (72), the center of the rear edge of the first plate (71), and the notch (78), and the horizontal member (32L) is inserted through this opening. The lower edge of the upper restricting piece (72) abuts against the upper edge of the horizontal member (32L), restricting the second fitting (7) from moving downward relative to the frame member (31LF), and the upper edge of the lower restricting piece (72) abuts against the lower edge of the horizontal member (32L), restricting the second fitting (7) from moving upward relative to the frame member (31LF), so the restricting pieces (72) function as restricting parts (10) that restrict the vertical movement of the second fitting (7). In this embodiment, the restricting piece (72) is positioned towards the vertical center of the upper and lower edges of the notch (78), but the upper and lower edges of the notch (78) may be positioned towards the vertical center of the restricting piece (72). In that case, with the first plate (71) and the second plate (73) surrounding the frame member (31LF), the upper edge of the notch (78) abuts against the upper edge of the horizontal member (32L), restricting the second fitting (7) from moving downward relative to the frame member (31LF), and the lower edge of the notch (78) abuts against the lower edge of the horizontal member (32L), restricting the second fitting (7) from moving upward relative to the frame member (31LF), so the notch (78) functions as a restricting part (10) that restricts the vertical movement of the second fitting (7).Furthermore, the shapes of the first plate (71) and the second plate (73) as viewed from the plane are not limited to those described above. The frame member (31) can be appropriately modified in a configuration that allows it to be surrounded and opened from the shorter side of the frame member (31). For example, both the first plate (71) and the second plate (73) can be L-shaped when viewed from the plane.

[0029] Next, we will explain how to attach and detach the handle structure (4) to the box pallet (1).

[0030] To attach the handle structure (4) to the box pallet (1), first, the first fitting (6) is brought close to the left frame member (31BL) of the rear wall panel (3B) from behind, and the first fitting (6) is positioned so that the opening of the first fitting (6) and the frame member (31BL) face each other, and the notch (63) formed in the inner plate portion (62) of the first fitting (6) and the horizontal member (32B) of the rear wall panel (3B) face each other. From this state, when the handle structure (4) is moved forward, the first fitting (6) encloses the frame member (31BL) and the notch (63) is positioned so as to sandwich the horizontal member (32B) from above and below, and the attachment of the first fitting (6) is completed. Subsequently, the second plate (73) of the second fitting (7) is swung to open the second fitting (7), and the handle body (5) is swung around the first fitting (6) side as an axis so that it follows the left wall panel (3L), and the first plate (71) is brought into contact with or close to the frame material (31LF) so that the horizontal member (32L) of the left wall panel (3L) is positioned between the upper and lower restricting pieces (72) of the first plate (71). Then, the second plate (73) is swung so that the horizontal member (32L) is positioned between the upper and lower edges of the notch (78) of the second plate (73), surrounding the frame member (31LF) with the first plate (71) and the second plate (73), engaging the engaging part (91) of the snap lock (9) attached to the first plate (71) with the hook part (79) of the second plate (73), and further swung the operating part to a position along the outer surface of the first plate (71), thereby completing the attachment of the second fitting (7) to the frame member (31LF).

[0031] The outer plate portion (61), intermediate plate portion (64), and first inner plate portion (62) of the first fitting (6) prevent the first fitting (6) from detaching from the frame material (31BL) in the forward and left / right directions, and the attachment of the second fitting (7) to the frame material (31LF) prevents the first fitting (6) from detaching from the frame material (31BL) in the rearward direction. In addition, the notch portion (63) (regulating portion (10)) of the first fitting (6), and the regulating piece portion (72) and notch portion (78) (regulating portion (10)) of the second fitting (7) prevent the handle structure (1) from shifting vertically. In this way, the handle structure (4) is securely attached to the box pallet (1).

[0032] To remove the handle structure (4) from the box pallet (1), first, the operating part of the latch (9) is swung upright from the left side of the first plate (71) to release the engagement of the engaging part (91) and the hook part (79). Then, the second plate (73) is swung to open the second fitting (7), and the handle structure (4) is swung around the first fitting (6) side as an axis to remove the second fitting (7) from the frame (31LF). After that, the first fitting (6) is moved backward and removed from the frame (31BL), completing the removal of the handle structure (4) from the box pallet (1).

[0033] Thus, the handle structure (4) has a simple configuration and can be easily and securely attached to the box pallet (1), and can also be easily removed. In this case, the handle structure (4) is attached so as to follow the left wall panel (3L) via the rear wall panel (3B) by having the first fitting (6) attached to the frame member (31BL) and the second fitting (7) attached to the frame member (31LF). However, by reversing the front-to-back direction with the axial direction, the first fitting (6) can be attached to the right frame member (31BR) of the rear wall panel (3B), and the second fitting (7) can be attached to the front frame member (31RF) of the right wall panel (3R), so that it follows the left wall panel (3R) via the rear wall panel (3B). Furthermore, even if the horizontal members (32B) of the rear wall panel (3B) and the horizontal members (32L) of the left wall panel (3L) are positioned at different vertical locations, the vertical displacement of the handle structure (4) is prevented by engaging one of the restricting parts (10) of the first fitting (6) and the second fitting (7) with one of the horizontal members (32B) (32L) of the rear side panel (3B) and the left side panel (3L).

[0034] Next, a second embodiment of the present invention will be described with reference to Figures 5 and 6. Note that the handle structure (104) according to the second embodiment differs from the handle structure (4) according to the first embodiment only in its configuration of the first fitting; therefore, the other components will not be described.

[0035] The first fitting (106) of the handle structure (104) is fixed orthogonally to one end (51) of the handle body (5) by fastening means such as welding, and includes a plate-shaped outer plate portion (161) that is positioned to abut or approach the left frame member (31BL) of the rear wall panel (3B) and the rear frame member (31LB) of the left wall panel (3L) from the outside (left side in this embodiment), a plate-shaped inner plate portion (162) that is positioned opposite the outer plate portion (161) and is configured to abut or approach the left frame member (31BL) of the rear wall panel (3B) from the inside (right side in this embodiment), and a plate-shaped intermediate plate portion (164) that connects the outer plate portion (161) and the inner plate portion (162). The first fitting (106) is U-shaped or U-shaped (U-shaped in this embodiment) when viewed from a plane that opens toward the second fitting (7) (forward in this embodiment). The outer panel (161) is configured such that its front-to-back length is longer than that of the inner panel (162), and it has protruding pieces (165) that are formed to project to the right from the upper and lower ends (see Figure 7). The lower edge of the upper protruding piece (165), the vertical center of the front edge of the outer panel (161), and the upper edge of the lower protruding piece (165) form a U-shaped locking portion (166) when viewed from the front, and the handle structure (104) is configured to enclose the horizontal member (32L) of the left side wall panel (3L) from the vertical and left directions when attached to the box pallet (1). The tip of the inner plate portion (162) has a U-shaped notch (163) cut out from the tip edge, and when the handle structure (104) is attached to the box pallet (1), the cross member (32B) of the rear wall panel (3B) is inserted between the upper and lower edges of the notch (163). Note that the notch (163) has the same configuration as the notch (63) of the handle structure (4) according to the first embodiment, so a detailed illustration has been omitted.In this configuration, when the first fitting (6) is attached to the frame members (31BL) (31LB), the lower edge of the upper protruding piece (165) and the upper edge of the notch (163) come into contact with the upper edges of the horizontal members (32L) (32B), thereby restricting the first fitting (106) from moving downward relative to the frame members (31BL) (31LB). The upper edge of the lower protruding piece (165) and the lower edge of the notch (163) come into contact with the lower edges of the horizontal members (32L) (32B), thereby restricting the first fitting (106) from moving upward relative to the frame members (31BL) (31LB). The protruding piece (165) and the notch (163) function as restricting parts (10) that restrict the vertical movement of the first fitting (106). In other words, the first fitting (106) is attached to the frame members (31BL) (31LB) by wrapping around them from the shorter side and engaging with the horizontal members (32L) (32B).

[0036] The first fitting (106) is configured such that the frame members (31BL)(31LB) can pass between the ends of the outer plate portion (161) and the inner plate portion (162) from the shorter side of the frame members (31BL)(31LB), and the region formed by the outer plate portion (161), the intermediate plate portion (164), and the inner plate portion (163) encloses the frame members (31BL)(31LB) in a wrapping manner from the shorter side of the frame members (31BL)(31LB). Preferably, when the first fitting (106) is attached to the frame members (31BL)(31LB), the first fitting (106), the frame members (31BL)(31LB), and the cross members (32L)(32B) are configured such that the first fitting (106) can swing freely at a slight angle around the frame member (31BL) as an axis. Furthermore, in this embodiment, the first fitting (106) is formed by bending a single sheet of metal, but it is not limited to this, and may be formed by joining separate sheet metals by welding or the like.

[0037] Next, we will explain how to attach the handle structure (104) to the box pallet (1).

[0038] To attach the handle structure (104) to the box pallet (1), first, the first fitting (106) is brought close to the left frame member (31BL) of the rear wall panel (3B) from behind, and the first fitting (106) is positioned so that its opening and the frame member (31BL) face each other, and the notch (163) formed in the inner plate portion (162) of the first fitting (106) and the cross member (32B) of the rear wall panel (3B) face each other. From this state, when the handle structure (104) is moved forward, the first fitting (106) is positioned so that it encloses the frame member (31BL) and the notch (163) sandwiches the cross member (32B) from above and below. Next, the second plate (73) of the second fitting (7) is swung to open the second fitting (7), and then the handle body (5) is swung around the first fitting (106) side so that it follows the left wall panel (3L) so that the horizontal member (32L) of the left wall panel (3L) is positioned between the upper and lower protruding pieces (165) of the outer plate (161) of the first fitting (106), and the horizontal member (32L) is positioned between the upper and lower restricting pieces (72) of the first plate (71) of the second fitting (7). As a result, the first fitting (106) encloses the frame members (31BL) (31LB), and the notched portion (163) and the protruding piece portion (165) are positioned to sandwich the horizontal members (32B) (32L) from above and below, thus completing the attachment of the first fitting (106) to the frame members (31BL) (31LB). The subsequent attachment of the second fitting (7) to the frame member (31LF) is the same as that of the handle structure (4) according to the first embodiment, so the explanation is omitted. The handle structure (104) can be reversed with the front-rear direction as the axial direction, and the first fitting (106) is attached to the right frame member (31BR) of the rear wall panel (3B), and the second fitting (7) is attached to the front frame member (31RF) of the right wall panel (3R), so that it can be attached along the left wall panel (3R) via the rear wall panel (3B).

[0039] Thus, the first fitting (106) functions as a restricting part (10) with its protruding piece (165) and notched part (163) corresponding to the horizontal members (32B) and (32L) of the rear wall panel (3B) and left wall panel (3L), respectively. Therefore, when the horizontal members (32B) and (32L) of the rear wall panel (3B) and left wall panel (3L) are in the same vertical position, vertical displacement of the handle structure (104) is more reliably prevented. Even when the horizontal members (32B) and (32L) of the rear wall panel (3B) and left wall panel (3L) are in different vertical positions, the protruding piece (163) corresponds to the horizontal member (32L) of the left wall panel (3L), so the restricting parts (10) of both the first fitting (106) and the second fitting (7) function, and vertical displacement of the handle structure (104) is reliably prevented. Furthermore, the protruding piece (165) can also be formed on the outer plate portion (61) of the first fitting (6) of the handle structure (4) according to the first embodiment.

[0040] Furthermore, if the horizontal member (32B) of the rear wall panel (3B) and the horizontal member (32L) of the left wall panel (3L) are positioned at different vertical locations, it is possible, for example, to shorten the length of the handle body (5) and attach the first fitting (106) to the rear frame member (31LB) of the left side panel (3L) (see Figures 7 and 8). In this case as well, since the protruding piece (163) corresponds to the horizontal member (32L) of the left wall panel (3L), both the restricting portion (10) of the first fitting (106) and the second fitting (7) function, and vertical displacement of the handle structure (104) is reliably prevented. Furthermore, with the above configuration, for example, in the case of a handle structure (104) having a handle body (5) corresponding to the front-to-back length of the left and right side wall panels (3L) (3R) and the left-to-right length of the rear side wall panel (3B), it becomes possible to attach it to the left and right side wall panels (3L) (3R) respectively without going through the rear side wall panel (3B), and also to attach it to the rear side wall panel (3B) without going through the left and right side wall panels (3L) (3R), thereby improving the flexibility of handling. Furthermore, regarding the length of the handle body (5), a separate handle structure (104) may be created that includes handle bodies (5) of different lengths. Alternatively, the handle body (5) may be constructed from an extendable rod-shaped member, and the handle structure (104) may be configured to be applicable even when the distance between frame members (31) differs. For example, it may be attached to the left frame member (31BL) and right frame member (31BR) of the rear wall panel (3B), to the rear frame member (31LB) and front frame member (31LF) of the left wall panel (3L), or to the rear frame member (31RB) and front frame member (31RF) of the right wall panel (3R).With this configuration, the first fitting (106) and the second fitting (7) can be attached to any frame member (31) for box pallets (1) whose side wall panels (3) have different horizontal lengths. The first fitting (106) and the second fitting (7) can be attached to the frame member (31) of the same side wall panel (3). Furthermore, the first fitting (106) and the second fitting (7) can be attached to frame members (31) located at adjacent corners of adjacent side wall panels (3). In any case, the restricting parts (10) of the first fitting (106) and the second fitting (7) function together, further improving the freedom of handling while maintaining safety and operability. Thus, if the handle structure (104) can be easily attached to and detached from any side wall panel (3), the movement and alignment of the box pallets (1) becomes easier. [Explanation of Symbols]
