Description

  The present invention relates to a lock structure for a side plate for raising and lowering in a folding container.

  Conventionally, a rectangular bottom plate, a rectangular frame-shaped mouth frame disposed above the bottom plate, and a folding side plate respectively disposed between a pair of opposite sides of the bottom plate and a pair of opposite sides of the mouth frame. A side plate for raising / lowering disposed between the other pair of opposite sides of the bottom plate and the other pair of opposite sides of the mouth frame, and a lid plate attached to the mouth frame so as to be openable and closable. The upper end of the upper side plate is composed of an upper side plate for the upper half and a lower side plate for the lower half. A folding container is known in which a lower end of a lower plate is rotatably connected to a bottom plate and a lower end of an upper plate and an upper end of a lower plate are rotatably connected.

  Conventionally, the lid plate is locked with a lock member with respect to the mouth frame, but the raising and lowering side plate is generally not locked with respect to the bottom plate.

  In the folding container as described above, in the state where the box is assembled and the stored items are stored therein, and the mouth frame is closed with the lid plate, the side plate for raising is pushed from the outside to rotate the side plate for raising and lowering inside. This makes it possible to take out the stored items in the folding container. For this reason, when the stored item is stored in the folding container and stored or transported, there is a risk that the stored item is stolen by rotating the raising side plate.

  On the other hand, there is known a device in which a hole communicating with two members is provided and locked to the communicating hole with a lock member as disclosed in Patent Document 1 or Patent Document 2. The lock member has a head at the upper end and a hook at the lower end. The lock member is inserted into a hole communicating with the upper and lower sides, the head is positioned on the surface side of the upper hole, and the lower surface of the lower hole. The hook is positioned on the side to lock.

  Therefore, in a state where a lower protrusion is projected outward at the lower end of the face plate of the raising side plate, an upper hole is formed in the lower protruding edge, and the raising side plate is in a vertical posture. A patent document in which a lower hole communicating with the upper hole in the vertical direction is formed at a portion of the outer end portion of the bottom plate on which the lower surface of the lower projecting edge portion is placed, the upper end is a head, and the lower end is provided with a hooking portion. No. 1 and Patent Document 2 are inserted along the outer surface of the raising / lowering side plate along the outer surface of the raising / lowering side plate and inserted into the upper hole and the lower hole that communicate with each other up and down, and the upper surface of the upper hole. It is conceivable to prevent the stored items from being stolen by positioning the head on the side and locking the hook by positioning the hook on the lower surface side of the lower hole.

However, even if an attempt is made to lock the lower end portion of the side plate for raising and lowering to the bottom plate using the locking member shown in Patent Document 1 or Patent Literature 2 described above, the lock by the lock member is obstructed by the face plate of the side plate for raising and lowering. There is a problem that it is difficult to work, and in particular, the face plate portion of the side plate for raising and lowering may be provided with a card insertion on the outer surface, or ribs may be provided integrally with the face plate on the outer surface portion of the face plate. In such a case, even if an attempt is made to insert the lock member along the outer surface of the face plate of the raising / lowering side plate from the upper side to the lower side and connect the lock member, the insertion of the lock member cannot be performed because the card insertion or the rib becomes an obstacle. There's a problem.

It is a continuous surface.

  In the embodiment shown in the accompanying drawings, the lock hole 13 constituted by the upper hole 11 and the lower hole 12 is a horizontally long hole that is longer in the left-right direction than the front and rear, and the upper hole that communicates vertically with the lock hole 13. As shown in FIG. 7B, the inner surfaces of the left and right sides of 11 and the inner surfaces of the left and right sides of the lower hole 12 (that is, the inner surfaces of both sides of the lock hole 13) are substantially vertically continuous.

  In use, the folding container 1 having the above-described configuration is such that both the folding side plates 4 stand upright to be in a vertical posture, and then the both side tilting side plates 9 stand up and assembled into a box shape. 7 is opened, the stored items are stored therein, and then the lid plate 7 is closed, so that the stored items are transported and stored. Further, when the stored items are not stored, both the raising and lowering side plates 9 are rotated to be positioned in the mouth frame 3 in a substantially horizontal posture, and then both the raising and lowering side plates 9 are centered on the intermediate shaft support portion 8. The whole can be folded compactly by folding inward.

  By the way, there is a case where the lid plate 7 and the side plate 9 for raising and lowering are locked and stored and transported so that the lid plate 7 and the side plate 9 for raising / lowering cannot be opened in a state where the stored items are stored in a box shape.

  In this case, the lid plate 7 is connected to the mouth frame 3 by the lock member 16 to lock the lid plate 7 so that the lid plate 7 is not opened, and the raising / lowering side plate 9 is connected to the bottom plate 2 by the lock member 16 The side plate 9 is locked so as not to open.

  That is, with the lid plate 7 closed, the lock member 16 as shown in FIG. 13 is inserted and locked in the lid lock hole 24 formed by the holes 22 and 62 communicating vertically.

  11 is inserted into a lock hole 13 formed by an upper hole 11 and a lower hole 12 communicating with each other in a state where the side plate 9 for raising and lowering is set in a substantially vertical posture. To lock.

  The lock member 16 is integrally formed of synthetic resin, and includes a head portion 14 at the upper end and a hook portion 15 at the lower end. In the embodiment shown in FIG. 14, the shaft portion 19 is integrally projected from the widened head portion 14, and the hook portions 15 having elasticity from both side surfaces of the tip portion of the shaft portion 19 are directed obliquely upward. It has a V-shape. Further, a front bulging portion 20 and a rear bulging portion 21 are integrally projected on the front and rear surfaces of the protruding base portion from the head portion 14 of the shaft portion 19, and the upper portions of the front and rear bulging portions 20, 21 are the lock holes 13. It is almost the same size as the upper end. In addition, the front and back of the lower part of the front and rear bulging parts 20 and 21 are inclined surfaces, respectively, and the front surfaces of the lower parts of the front and rear bulging parts 20 and 21 are inclined downward toward the front or rear side as they go downward. Furthermore, the left and right sides of the lower part of the front and rear bulging parts 20 and 60 are inclined surfaces, and the left and right side surfaces of the lower part of the front and rear bulging parts 20 and 21 are directed toward the left or right side as they go downward. And tilted down.

  In order to insert the lock member 16 having the above configuration into the lid lock hole 24, the V-shaped hooking portion 15 at the lower end of the shaft portion 19 of the lock member 16 is inserted into the lid lock hole 24 from above. The hook portion 15 is elastically deformed and passes through the lid lock hole 24 while elastically deforming so that the upper ends of the hook portions 15 on both sides approach each other, and the upper end of the hook portion 15 is locked for the lid. When it passes through the lower end of the hole 24, it is elastically restored to the original V shape, and the hook 15 is prevented from coming off upward. As a result, the head portion 14 is positioned on the upper surface side of the hole 22 and the hook portion 15 is positioned and locked on the lower surface side of the hole 23.

  In this case, since there is no obstacle above the lid lock hole 24, the lock member 16 can be inserted into the lid lock hole 24 from directly above the lid lock hole 24.

  On the other hand, in order to insert the lock member 16 into the lock hole 13, the upper hole 11 of the lock hole 13 is provided in the lower protruding edge portion 10 protruding outward from the lower end of the face plate 9 a, so The face plate 9a will be located immediately behind, so that when the lock member 16 is inserted into the lid lock hole 24, the user holds the lock member 16 by hand and tries to insert it from directly above the lock hole 13. Then, the face plate 9a gets in the way and it is very difficult to insert it from directly above. In particular, as shown in FIG. 11A, a protruding equipment such as a card slot 25 is provided on the outer surface of the face plate 9a, or the face plate 9a In such a case, since the protruding equipment such as the card insert 25 and the rib protrude further forward than the face plate 9a, when the lock member 16 is inserted, car Although the operator's hand or the lock member 16 hits the protruding equipment such as the insert 25 or the rib, it cannot be substantially inserted. Is inclined so as to be on the near side as it goes upward, so that the lock member 16 can be inserted in an inclined state so that it is on the near side as shown in FIG. Thus, the V-shaped hooking portion 15 at the lower end of the shaft portion 19 of the lock member 16 is inserted into the lock hole 13 obliquely from above without being obstructed by the outer surface of the face plate 9a or the card insert 25. When the hook 15 is elastically deformed and passes through the lock hole 13 while being elastically deformed so that the upper ends of the hooks 15 on both sides come close to each other, the upper end of the hook 15 passes through the lower end of the lock hole 13. Elastically restored to a letter shape Hooking portion 15 becomes a stopper upward, by this, so that the engaging portion 15 on the lower surface of the lower hole 12 with the head 14 on the upper surface of the upper hole 11 is positioned is locked located.

  Thus, by inserting the lock member 16 through the lock hole 13 and connecting the raising / lowering side plate 9 to the bottom plate 2, the raising / lowering side plate 9 is locked so as not to rotate.

  Here, the lock member inserted obliquely by connecting the front inner surfaces of the upper hole 11 and the lower hole 12 communicating vertically with the vertical side plate 9 in a vertical posture substantially vertically. After the insertion, the locking member 16 can be brought into a vertical posture along the substantially vertical continuous portion of the inner surface on the front side of the upper hole 11 and the lower hole 12 communicating with each other in the vertical direction. It can be prevented from tilting, and the appearance is improved.

  When the lock member 16 is in a vertical posture, the front surface of the front bulge portion 20 and the rear surface of the rear bulge portion 21 projecting from the front and rear surfaces of the base portion protruding from the head portion 14 of the shaft portion 19 are the upper portion of the lock hole 13. The lock member 16 is held in a vertical posture by contacting or in close proximity to an inner front surface and a rear inner surface of an upper hole 11 so that the lock member 16 is not tilted and rattled.

  In order to release the lock by the lock member 16, the protruding base portion of the shaft portion 19 of the synthetic resin lock member 16 from the head portion 14 is cut by a cutter as shown in FIG. The upper end of the cutting surface is pushed from above, so that it is discharged out of the bottom plate 2 from the recessed portion opened downward on the lower surface side of the support protrusion 18 as shown in FIG. 15A, or as shown in FIG. As shown, it is discharged to the outer side of the mouth frame 3 from the concave portion opened in the outer side provided in the mouth frame 3.
