handle support portions

50, 50.

As shown in fig. 12, the cutout 63A in the turning shaft portion 63 of the handle 60 is formed in a substantially L-shape extending from the end portion on the side of the outer protrusion 51 to the center portion in the axial direction at the portion farthest from the grip portion 61 in the turning shaft portion 63 and extending from there curvedly to the side away from the central recess portion 25. Then, a part of the turning shaft 63 on the outer projection 51 side is cut into a tab shape by the notch 63A to form a handle side engaging portion 64. Further, the handle-side engaging portion 64 is narrowed toward the distal end.

As shown in fig. 1, when the handle 60 is in the non-use posture in which it overlaps the second long side surface 12B of the first casing portion 21, the notch 63A of the pivot shaft 63 is directed upward through the receiving opening 50K as shown in fig. 14 and 15. As shown in fig. 16, when the second casing portion 22 is closed with respect to the first casing portion 21 and the lid 23 is further closed with respect to the second casing portion 22, the receiving opening 50K of the handle support portion 50 is closed by the closing wall 48 of the lid 23. In this regard, in the present embodiment, the "plugging portion" of the present invention is configured by the extension protrusion 43 and the plugging wall 48. The cover-side engaging portion 49 extending from the closing wall 48 is in a state of protruding into the notch 63A of the rotation shaft 63.

When the handle 60 is turned from this position as shown in fig. 17, the leg portion 62 of the handle 60 abuts against the connecting wall 53 of the handle support portion 50 (fig. 17 shows a state before the leg portion 62 abuts against the connecting wall 53), and the handle 60 is in a use posture in which it is substantially upright from the second long side surface 12B. In the process of moving the handle 60 from the non-use posture to the use posture, the handle-side engaging portion 64 projects into the engaging hole 49A of the cover-side engaging portion 49, and the handle-side engaging portion 64 engages with the cover-side engaging portion 49. More specifically, the handle-side engaging portion 64 is located closer to the receiving opening 50K of the handle support portion 50 than the engaging rod 49B on the tip side of the engaging hole 49A of the cover-side engaging portion 49. Thus, the cover-side engaging portion 49 does not come off the handle support portion 50. When the handle 60 is in the use position, the leg portion 62 of the handle 60 is sandwiched between the outer protrusion 51 and the inner protrusion 52 of the handle support portion 50 and is held stably, and the engagement between the handle-side engagement portion 64 and the cover-side engagement portion 49 is electrically stabilized.

Although not shown, when the handle-side engaging portion 64 projects into the engaging hole 49A in a state where the second casing portion 22 and the lid 23 are arranged at the normal closed position, a first gap is formed between the inner surface of the handle-side engaging portion 64 and the upper surface of the engaging rod 49B. Thus, even in a state where the second casing portion 22 or the lid 23 is slightly lifted from the normal closed position (i.e., a half-opened state), the handle-side engaging portion 64 can be engaged by protruding into the engaging hole 49A.

As shown in fig. 17, when the handle 60 is in the use posture with respect to the second long side surface 12B in the state where the second casing portion 22 and the lid 23 are arranged at the regular closed position, a second gap C1 is formed between the inner surface of the handle side engaging portion 64 and the upper surface of the engaging rod 49B. Thus, when the box 10 is lifted up with the first buckle 15 or the second buckle 16 forgotten to be fastened, the second box portion 22 or the lid 23 is in a half-opened state, and thus, it is possible to notice that the

buckles

15 and 16 are forgotten to be fastened.

It should be noted that the structure may be such that only the first space is provided and the second space C1 is not provided, and the second casing portion 22 and the lid 23 are completely closed when the handle 60 is turned to the use position when the second casing portion 22 or the lid 23 is in the half open state.

The above description relates to the structure of the case 10 of the present embodiment. Next, the operational effects of the case 10 will be described. When the luggage is taken out of and put into the first casing portion 21 or the second casing portion 22 of the casing 10, the first buckle 15 or the second buckle 16 may be removed with the casing 10 set in a horizontal posture as shown in fig. 1, and the second casing portion 22 or the cover 23 may be opened as shown in fig. 5 or 7.

When the second body portion 22 and the lid 23 are closed and the first buckle 15 and the second buckle 16 are fastened after the taking in and taking out of the luggage is completed, the luggage 10 can be carried by gripping the handle 60. However, the case 10 may be transported by holding the handle 60 in a state where the second case portion 22 and the lid 23 are closed and the fastening of both or either of the first buckle 15 and the second buckle 16 is forgotten. However, in the case 10 of the present embodiment, when the handle 60 is gripped and turned for transportation, as shown in fig. 17, the handle-side engaging portion 64 of the handle 60 engages with the cover-side engaging portion 49. Thereby, the lid 23 is fixed to the first tank portion 21, and also to the second tank portion 22 between the first tank portion 21 and the lid 23.

As described above, in the case 10 of the present embodiment, it is possible to prevent the luggage from falling off due to forgetting to fix the second case portion 22 and the lid 23 by the first buckle 15 or the second buckle 16. When slightly rotated from the position standing upright from the second long side surface 12B, the handle 60 abuts against the connecting wall 53 and is held in the use posture. Thus, as shown in fig. 4, when box 10 is placed on the floor or the like in the use posture, handle 60 is also held in the use posture, and the state in which second box section 22 and lid 23 are fixed to first box section 21 can be maintained.

Further, since the handle-side engaging portion 64 and the cover-side engaging portion 49 are housed in the handle support portion 50 and engaged with each other, they can be protected from collision with other members. In addition, the complicated engaging structure of the handle-side engaging portion 64 and the cover-side engaging portion 49 can be hidden, and the appearance can be improved. Further, the housing opening 50K of the handle support portion 50 for housing the cover-side engaging portion 49 is closed by the closing wall 48 provided in the cover 23, and therefore, the appearance can be improved.

[ other embodiments ]

The present invention is not limited to the above-described embodiments, and for example, the embodiments described below are also included in the technical scope of the present invention, and various modifications other than the following can be made without departing from the gist of the present invention.

(1) In the case 10 of the above embodiment, the cover-

side engaging portions

49 and 49 are configured to protrude into both of the pair of handle support portions 50 and engage with the handle-

side engaging portions

64 and 64, but the cover-side engaging portion 49 and the handle-side engaging portion 64 may be configured to engage only in one of the handle support portions 50.

(2) Further, one handle support portion may be provided between the pair of

leg portions

62, 62 of the handle 60, and the cover-side engaging portion may protrude into the handle support portion and engage with the handle-side engaging portion.

In this case, for example, an elastic engagement portion for holding the handle 60 in the use posture with respect to the first casing portion 21 may be provided between the first casing portion 21 and the handle 60.

(4) In the above-described embodiment, the handle-side engaging portion 64 is configured to protrude into the engaging hole 49A of the cover-side engaging portion 49 and engage the cover-side engaging portion 49 with the handle-side engaging portion 64 (see fig. 17), but an engaging hole may be provided on the rotation shaft portion 63 side of the handle 60 and the cover-side engaging portion may be configured to engage with the engaging hole. Specifically, for example, as shown in fig. 20 (a), a pair of handle

side engaging portions

64V, 64V are provided on the rotation shaft portion 63 of the handle 60, and an engaging hole 63V is provided between these handle

side engaging portions

64V, 64V. The cover-side engaging portion 49V having a substantially T-shape may be configured to engage with the engaging hole 63V. As shown in fig. 20 (B), the turning shaft portion 63 of the handle 60 may be provided with a protruding piece 63H protruding laterally, an engagement hole 63W may be provided in the protruding piece 63H, and a cover side engagement portion 49W having a substantially L shape may be engaged with the engagement hole 63W.

(5) In the above embodiment, the "blocking portion" of the present invention that blocks the receiving opening 50K of the handle support portion 50 is constituted by the extension protrusion 43 and the blocking wall 48 provided at the end thereof, but the "blocking portion" of the present invention may be constituted by only the extension protrusion 43 without the blocking wall 48. In this case, for example, the cover-side engaging portion 49 may be configured to protrude from the upper surface or the side surface of the inside of the extension protrusion 43. For example, the "stopper portion" of the present invention may be configured to be fitted to the outside or inside of the receiving opening 50K of the handle support portion 50.

(6) In the above-described embodiment, in addition to the engagement between the handle-side engaging portion 64 and the cover-side engaging portion 49, the first buckle 15 and the second buckle 16 for the second casing portion 22 and the cover 23 are provided, and the second casing portion 22 and the cover 23 can be fixed to the closed positions, respectively, but the first buckle 15 and the second buckle 16 may not be provided. Further, only one of the first buckle 15 and the second buckle 16 may be provided. By providing the first buckle 15 and the second buckle 16, the fixing strength of the second casing portion 22 or the lid 23 at the closed position can be increased.
