Summary of the Invention

Problems to be Solved by the Invention

[0004] In the above-described conventional lid member, when the pallet that has been propped up falls down or the load of the communication device is applied to the lid member, the lid member may bend and the locking may be released, and the lid member may come off. In view of this, it is desired to develop a lid member that is difficult to come off even when a load is applied from the inside of the communication device housing portion.

Means for Solving the Problems

[0005] The lid member of this disclosure is a lid member for closing an opening in a communication device housing that opens on one surface of a transport device, and comprises: a base plate that fits into the opening of the communication device housing; a hinge projection provided on the first side of the base plate, which is inserted into a hinge receiving portion of the communication device housing and rotatably engages with it; and a locking piece provided on the second side opposite to the first side, which is inserted into an insertion opening between the opening edge of the opening of the communication device housing and the inner wall of the communication device housing and locks to the inner wall from the outside. [Effects of the Invention]

[0006] According to the lid member of this disclosure, the lid member is attached by inserting the hinge projection on the first side of the lid member, rotating it, and inserting the locking piece on the second side of the lid member into the outside of the inner wall of the communication equipment housing and locking it in place. Since the locking piece locks to the inner wall from the outside, even if a load is applied to the lid member from the inside of the communication equipment housing and the base plate bends, the locking piece will move towards the inner wall and strengthen the lock, making it difficult to come off.

[0008] The lid member 10 of this disclosure will be described below with reference to Figures 1 to 13. Figure 1 shows a pallet set 100 comprising a lid member 10 and a pallet 50 having a communication equipment housing section 60 that is closed off by the lid member 10. The pallet 50 has a plurality of beam sections 52 on the lower surface of a rectangular deck board 51, with fork insertion spaces 53 between these beam sections 52. The beam sections 52 are located at the four corners of the pallet 50, the center of each side, and the center of the pallet 50. Furthermore, the pallet 50 of this embodiment is a welded pallet in which an upper member 50A and a lower member 50B, which are injection molded, are welded together.

[0009] In the center of the pallet 50, a communication equipment housing section 60 is formed on the upper surface of the deck board 51, having a roughly rectangular opening 60A. Hereafter, the longitudinal direction of this opening 60A will be referred to as the first horizontal direction H1, and the short direction of the opening 60A will be referred to as the second horizontal direction H2. As shown in Figure 2, the communication equipment housing section 60 is formed from the upper surface of the deck board 51 to a height of about two-thirds of the way up from the top of the central beam section 52 of the pallet 50 (hereinafter referred to as the "central beam section 52A" as appropriate). The communication equipment housing section 60 has a rectangular tubular upper inner wall 61 extending downward from the opening 60A on the upper member 50A side of the central beam section 52A.

[0010] As shown in Figure 3, the central beam section 52A includes a lower central wall 70 located in the center of the first horizontal direction H1 in the area directly below the opening 60A on the lower member 50B side, and lower inner walls 71 located on both sides of the lower central wall 70. The distance between the lower end of the upper inner wall 61 and the upper ends of the lower inner wall 71 and the lower central wall 70 is approximately 1 / 5 to 1 / 6 of the height of the pallet 50.

[0011] As shown in Figures 2 and 3, the lower central wall 70 has a rectangular notch 70K formed in the upper end portion located below the opening 60A, and the bottom 70S of this notch 70K is the lower end of the communication equipment housing 60. Each lower inner wall 71 has an inner surface that is on the same plane as or slightly outside the inner surface of the upper inner wall 61, and has a "U" shaped cross-section. The upper end of each lower inner wall 71 is provided with a taper 71A that goes inward as it goes down. In addition, each lower inner wall 71 has projecting ribs 71B on both sides facing the lower central wall 70 that are positioned to move closer to each other.

[0012] A rectangular parallelepiped-shaped communication device 110 is housed in the communication device housing 60. In this embodiment, the communication device 110 is, for example, an active RFID tag with a built-in battery that constantly emits a signal. As shown in Figures 4 to 6, when the communication device 110 is housed in the communication device housing 60 through the opening 60A, a small gap is created between the communication device 110 and the upper inner wall 61, and the device is pressed into the inside of the multiple rib supports 71B of the lower inner wall 71. The lower end of the communication device 110 is located slightly above the bottom 70S of the notch 70K in the lower central wall 70. When inserting the communication device 110 into the communication device housing 60, even if it comes into contact with the upper end of the lower inner wall 71 midway, it is guided inward by the taper 71A, allowing for smooth insertion of the communication device 110.

[0013] As mentioned above, the communication device housing section 60 can be closed off by the cover member 10. The cover member 10 will now be described in conjunction with the structure of the communication device housing section 60 to which the cover member 10 is attached.

[0014] As shown in FIGS. 7 and 8, the lid member 10 has a base plate 11 corresponding to the opening 60A (see FIG. 1) of the communication device housing portion 60, and an annular side wall 12 that hangs down from a position slightly inside the outer edge of the base plate 11. From the lower surface of the base plate 11, support protrusions 13 that extend outward from the annular side wall 12 protrude. The support protrusions 13 are respectively arranged at the four corners of the base plate 11 and at the center of each side (excluding the second side 11B described later). The outer end surface of the support protrusion 13 is flush with the outer end surface of the base plate 11. Further, as shown in FIG. 9, among the support protrusions 13, an extension portion 13A that extends downward is provided on the support protrusion 13 at the center of one side (hereinafter, appropriately referred to as the "first side 11A") that faces in the second horizontal direction H2, and the other side is referred to as the "second side 11B"). The amount of protrusion of the extension portion 13A from the annular side wall 12 is significantly smaller than the amount of protrusion of the support protrusion 13 from the annular side wall 12, and an inclined surface 13B is provided at the lower end of the extension portion 13A.

[0015] On the other hand, as shown in FIGS. 2 and 10, on the upper inner side wall 61 of the communication device housing portion 60, an upper stepped portion 62 is formed whose cross-section becomes smaller in a stepped manner from the opening 60A, and the lower surface of the support protrusion 13 of the lid member 10 abuts thereon. Further, a lower stepped portion 63 is formed whose cross-section becomes smaller in a stepped manner from there, and the lower end surface of the annular side wall 12 of the lid member 10 abuts thereon.

[0016] Also, as shown in FIGS. 8 and 10, the lid member 10 includes an appliance restraining portion 14 that extends downward from the annular side wall 12 inside the annular side wall 12. The appliance restraining portion 14 has a cylindrical shape and is connected to the annular side wall 12 by four connecting walls 15. In a state where the communication device 110 is housed in the communication device housing portion 60 and the lid member 10 is attached, the appliance restraining portion 14 of the lid member 10 abuts on the communication device 110, preventing the communication device 110 from rattling in the vertical direction.

[0017] Next, the locking of the lid member 10 and the communication equipment housing 60 will be described. As shown in Figure 9, hinge projections 20 extending outward from the annular side wall 12 are provided at two positions on the first side edge 11A of the lid member 10, flanking the central support projection 13. The hinge projections 20 are flat and integrally molded with the lower surface of the base plate 11, and protrude outward from the first side edge 11A of the base plate 11 by the thickness of the plate. Furthermore, the lower surface of the hinge projections 20 is located above the lower end of the support projection 13.

[0018] Corresponding to these hinge projections 20, two hinge receiving holes 61H (see Figures 2 and 10) are formed in the upper inner wall 61 of the communication equipment housing 60. The upper edge of the hinge receiving hole 61H is aligned with the lower surface of the base plate 11, and the lower edge of the hinge receiving hole 61H is aligned with the stepped surface of the upper stepped portion 62. As a result, when the lower end of the support projection 13 is in contact with the upper stepped portion 62, the hinge projection 20 does not come into contact with the upper stepped portion 62 or the lower edge of the hinge receiving hole 61H.

[0019] As shown in Figure 7, the base plate 11 of the lid member 10 has a pair of outwardly extending portions 11E that extend outward from the second side edge 11B. The space between the pair of outwardly extending portions 11E of the base plate 11 is cut out so that it is flush with the outer surface of the annular side wall 12.

[0020] The lid member 10 comprises a pair of vertical wall portions 26 hanging down from the tips of a pair of outwardly extending portions 11E, and a horizontal wall portion 27 connecting the lower ends of the pair of vertical wall portions 26. As shown in Figures 7, 9, and 10, a locking portion 28 protruding inward is provided in the portion of the horizontal wall portion 27 located between the vertical wall portions 26. The upper surface 28A of the locking portion 28 extends horizontally flat, and the inner surface 28B of the locking portion 28 connects the inner end of the upper surface 28A and the lower end of the horizontal wall portion 27 at an angle. In addition, a tool hook portion 29 is formed protruding from the upper surface of the horizontal wall portion 27 that is exposed between the vertical wall portions 26, connecting the lower ends of the vertical wall portions 26. The outer surface of the tool hanging section 29 is flush with the outer surfaces of the vertical wall section 26 and the horizontal wall section 27, and the inner surface of the tool hanging section 29 is located further out than the inner surface of the vertical wall section 26.

[0021] The "locking piece 25" is composed of a pair of vertical wall sections 26, horizontal wall sections 27, a locking section 28, and a tool-hanging section 29. In other words, the locking piece 25 has a notch 25K in the center in the horizontal direction, and the tool-hanging section 29 is exposed from the notch 25K.

[0022] As shown in Figure 8, at both ends of the outward extension 11E in the first horizontal direction H1, connecting portions 30 are formed that protrude downward and connect the locking piece 25 and the annular side wall 12. In addition, a ridge portion 31 is formed on the annular side wall 12 that extends downward from the inner end of the outer connecting portion 30. As shown in Figure 10, the amount of protrusion of the ridge portion 31 from the annular side wall 12 is approximately the same as the amount of protrusion of the extension portion 13A from the annular side wall 12, and similar to the extension portion 13A, an inclined surface 31B is also formed at the lower end of the ridge portion 31.

[0023] As shown in Figures 2 and 3, the opening 60A of the communication equipment housing section 60 in the pallet 50 is provided with an extension section 60K corresponding to a pair of outwardly extending sections 11E. In the portion where this extension section 60K is provided, the portion of the upper inner wall 61 above the upper step section 62 is not formed, and the space between the outer edge of the extension section 60K and the upper end of the upper inner wall 61 is an insertion opening 65. The upper end of the upper inner wall 61 is provided with a locking section 66 that protrudes outward. As shown in Figure 10, the locking section 66 has a lower surface 66A that extends horizontally flat, and at its upper end, it has an outwardly sloping section 66B that slopes outward as it descends. In addition, the inner edge of the upper inner wall 61 is also provided with an inwardly sloping section 61B that slopes inward as it descends.

[0024] Next, the attachment of the lid member 10 to the communication equipment housing 60 will be described. First, as shown in Figure 2, the lid member 10 is positioned so that the locking piece 25 corresponds to the expanded portion 60K of the opening 60A of the communication equipment housing 60. Then, as shown in Figures 11 and 12, the hinge projection 20 of the lid member 10 is inserted into the hinge receiving hole 61H of the communication equipment housing 60 from diagonally above. Then, the lid member 10 is rotated using the hinge projection 20 as a pivot point so that the locking piece 25 is inserted into the insertion opening 65.

[0025] At this time, since the locking portion 66 has an outward inclined portion 66B, even if the locking portion 28 (inner surface 28B) of the lid member 10 comes into contact with the outer upper end of the upper inner wall 61, the locking piece 25 is guided to the insertion opening 65. Also, since the inner inclined portion 61B is provided on the inner edge of the upper inner wall 61, even if the annular side wall 12 on the second side 11B side of the lid member 10 comes into contact with the inner end of the upper inner wall 61, the annular side wall 12 is guided to the inside of the upper inner wall 61, making it easier for the locking piece 25 to reach the insertion opening 65.

[0026] When the second side 11B of the lid member 10 is pushed downward, the inner surface 28B of the locking portion 28 and the outer inclined portion 66B of the locked portion 66 are pressed against each other, causing the locking piece 25 to elastically deform outward. Then, when the locking portion 28 passes over the locked portion 66, the locking piece 25 elastically returns to its original position, and the upper surface 28A of the locking portion 28 and the lower surface 66A of the locked portion 66 face each other and lock together, and the locking piece 25 engages with the upper inner wall 61 from the outside (see Figures 10 and 13). This completes the installation of the lid member 10.

[0027] To remove the lid member 10, the following procedure is followed. Specifically, a tool such as a flathead screwdriver (not shown) is inserted between the pair of vertical wall portions 26 into the inside of the tool holder portion 29. At this time, the tool can be inserted into a suitable position for the work by abutting the upper surface of the horizontal wall portion 27 with respect to the portion inside the tool holder portion 29. Then, the tool is operated to push the tool holder portion 29 outward to release the locking portion 28 and the locked portion 66, and the locking piece 25 is pulled out of the insertion opening 65 by rotating the second side 11B of the lid member 10 upward, and then the lid member 10 is removed by pulling the hinge projection 20 out of the hinge receiving hole 61H.

[0028] As described above, the lid member 10 of this embodiment can be easily removed by placing a tool on the tool hook portion 29. Furthermore, since the hinge projection 20 is provided on the first side edge 11A of the lid member 10 and the locking portion 28 is provided only on the second side edge 11B, it is only necessary to operate one side of the opposing edges, making removal easier than a configuration where locking portions 28 are provided on both opposing edges. In addition, since the tool hook portion 29 connects the tips of a pair of vertical wall portions 26, the locking piece 25 is strengthened. Also, the load when a tool is placed on the tool hook portion 29 is distributed, making the tool hook portion 29 less likely to break. Furthermore, since the locking piece 25 is U-shaped, even if a tool is dropped, the tool will come into contact with the side wall portion 27 and is less likely to fall inside.

[0029] In conventional lid members, which have a pair of opposing sides of the base plate with locking parts that engage from the inside with the locking part of the communication equipment housing, if the pallet that was leaning against it falls over and the load of the communication equipment is applied to the lid member, the center of the lid member is pushed up, causing the lid member to bend in a direction that releases the locking, and the lid member may come off.

[0030] In contrast, in the pallet set 100 of this embodiment, the lid member 10 cannot be removed from the communication equipment housing 60 unless it is rotated using the hinge projection 20 as a pivot point. Furthermore, since the locking piece 25 engages with the upper inner wall 61 from the outside, even if the lid member 10 bends due to the load of the communication equipment 110 causing the central part of the lid member 10 to be pushed up, the locking piece 25 moves toward the upper inner wall 61, strengthening the engagement between the locking piece 25 and the upper inner wall 61 (the locking of the locking part 28 and the locked part 66). As a result, the lid member 10 is less likely to come off than in the conventional design.

[0031] Furthermore, when the hinge projection 20 is inserted into the hinge receiving hole 61H and the lid member 10 is rotated, or when the lid member 10 is attached, the lower end of the support projection 13 abuts against the upper stepped portion 62, preventing the hinge projection 20 from abutting against the upper stepped portion 62 and the lower edge of the hinge receiving hole 61H. This prevents the hinge projection 20 from being pressed against the upper stepped portion 62 or the hinge receiving hole 61H and subjected to excessive load, thus preventing damage to the hinge projection 20 when the lid member 10 is rotated or when luggage is placed on the lid member 10. In addition, since the hinge projection 20 is integrally molded with the lower surface of the base plate 11, the hinge projection 20 is strengthened and less prone to damage.

[0032] Furthermore, since a connecting portion 30 is formed on the outward extension portion 11E that connects the locking piece 25 and the annular side wall 12, the outward extension portion 11E and the locking piece 25 are reinforced, and damage is prevented.

[0033] Furthermore, in this embodiment, the device retaining portion 14 protrudes downward from the annular side wall 12, and this device retaining portion 14 is configured to abut against the communication device 110. Therefore, by using lid members 10 with different lengths of device retaining portion 14, it is possible to accommodate communication devices 110 of different lengths without changing the pallet 50.

[0034] [Other embodiments] (1) In the above embodiment, the lid member 10 was attached to the communication equipment storage section 60 of the pallet 50, but it may also be attached to the communication equipment storage section of other transport equipment, such as protective devices attached to the ends of trolleys or rolls.

[0035] (2) In the above embodiment, the pallet 50 was a welded pallet, but it may also be a one-piece molded pallet in which the entire pallet is formed as a single unit.

[0036] (3) In the above embodiment, the communication equipment housing section 60 was open to the upper surface (deck board 51) of the pallet 50, but it may also be open to the side of the beam section 52 or the like.

[0037] (4) In the above embodiment, the communication device 110 was an active tag, but it may also be a passive tag. In the case of a passive tag, it is conceivable that the holder to which the passive tag is attached is housed in the communication device housing section 60.

[0038] (5) The lid member 10 may be configured to include a holding portion for holding the communication device 110. For example, the device retaining portion 14 may be made into a rectangular cross-section, and the communication device 110 may be fitted inside it. In this case, the lid member 10 may hold the communication device 110 and then attach it to the communication device housing portion 60.

[0039] <Note> The following describes the features extracted from the above embodiment, explaining their effects and other aspects as needed. For ease of understanding, corresponding configurations in the above embodiment will be indicated in parentheses as appropriate, but these features are not limited to the specific configurations indicated in parentheses.

[0040] [Feature 1] In a lid member (10) that closes the opening (60A) of a communication device housing section (60) which opens on one surface (51) of a transport device (50), A base plate (11) that fits into the opening (60A) of the communication equipment housing section (60), A hinge projection (20) is provided on the first side (11A) of the base plate (11), and is inserted into the hinge receiving portion (61H) of the communication device housing (60) and engages rotatably, A lid member comprising: a locking piece (25) provided on the second side (11B) opposite to the first side (11A), which is inserted into a slot (65) between the opening edge of the opening (60A) of the communication device housing (60) and the inner wall (61) of the communication device housing (60), and which locks to the inner wall (61) from the outside.

[0041] According to the lid member of Feature 1, the lid member is attached by inserting the hinge projection on the first side of the lid member, rotating it, and inserting the locking piece on the second side of the lid member into the outside of the inner wall of the communication equipment housing and locking it in place. Since the locking piece locks to the inner wall from the outside, even if a load is applied to the lid member from the inside of the communication equipment housing and the base plate bends, the locking piece will move towards the inner wall and strengthen the lock, making it difficult to come off.

[0042] [Feature 2] The aforementioned locking piece (25) is A locking portion (28) engages with a locking portion (66) on the inner wall (61) of the communication device housing (60) with a recessed and recessed portion, A notch (25K) is cut out from the side end of the base plate (11) to the locking portion (28) or to a position closer to the locking portion (28), The lid member according to feature 1, further comprising a tool-hanging portion (29) through the notch (25K) that allows a tool to be hung from the outside of the base plate (11).

[0043] With the lid member of Feature 2, the locking can be released by placing a tool on the tool hook from the outside of the base plate through the notch. Furthermore, instead of providing locking parts on both opposing sides of the base plate, by arranging a locking part on one side and a hinge projection on the other, only the locking part needs to be operated, making removal easier.

[0044] [Feature 3] The notch (25K) is located in the lateral center of the locking piece (25), The locking piece (25) has a pair of vertical wall portions (26) arranged horizontally on either side of the notch (25K), and a horizontal wall portion (27) that connects the tips of the pair of vertical wall portions (26) and has the locking portion (28) and the tool hanging portion (29), The locking portion (28) is positioned at the base plate (11) side end of the side wall portion (27), The lid member according to feature 2, wherein the tool-holding portion (29) protrudes from the surface of the horizontal wall portion (27) that is exposed through the notch portion (25K) and connects the tips of the pair of vertical wall portions (26).

[0045] According to the lid member of Feature 3, the tool hook section connects the ends of a pair of vertical wall sections, thus reinforcing the locking piece. In addition, the load when a tool is hung on the tool hook section is distributed, making the tool hook section less prone to damage.

[0046] [Feature 4] The base plate (11) has a side wall portion (12) that extends from the inside of the outer edge toward the rear of the communication equipment housing portion (60), The lid member according to any one of features 1 to 3, wherein the hinge projection (20) extends outward from the side wall portion (12) and is integrated with the back surface of the base plate (11).

[0047] According to the lid component of Feature 4, the hinge projection is integrated with the back surface of the base plate, which strengthens the hinge projection and makes it less prone to breakage.

[0048] [Feature 5] The communication device housing section (60) opens into the upper wall of the transport device (50), and the hinge receiving section (61H) opens into the upper end of the inner wall (61). The lid member according to feature 4, further comprising a support projection (13) that protrudes outward from the side wall portion (12) and abuts against a lid support surface (62) provided on the inner wall (61) of the communication device housing portion (60), thereby preventing the hinge projection (20) from abutting against the lower opening edge of the opening of the hinge receiving portion (61H).

[0049] With the lid member of Feature 5, the support projection abuts against the lid support surface, preventing the hinge projection from abutting against the lower opening edge of the hinge receiving portion. This reduces the force applied to the hinge projection when attaching the lid member or when a load is applied to the lid member, thus preventing damage.

[0050] [Feature 6] The side wall portion (12) extends to fit inside the inner wall (61) of the communication device housing portion (60), The base plate (11) has an outwardly extending portion (11E) that extends outward from the second side (11B) and from its tip the locking piece (25) protrudes. The lid member according to feature 4, further comprising a connecting portion (30) that protrudes from the back surface of the outwardly extending portion (11E) and connects the side wall portion (12) and the locking piece (25).

[0051] According to the lid member of Feature 6, a connecting portion protrudes from the back surface of the outwardly extending portion, connecting the side wall portion and the locking piece. This reinforces the outwardly extending portion and the locking piece, preventing damage.
