The storable state and the foldable state of this foldable trash can The structure to switch to is described.

Japanese Utility Model Publication No. 5-42201

  When the front member (front panel) is pushed and moved in the back member (rear panel) direction from the accommodable state, the box disclosed in Patent Document 1 is the center portion in the front-rear direction of the left and right side members (side panels). Is folded inward, and the bottom member (bottom panel) is raised so as to face the back member to be folded (finished state). Further, when the front member is pulled away from the back member from the folded state, the side member is extended along with the movement of the front member, and the bottom member is collapsed to be accommodated. The And in this accommodation possible state, the side member is extended in the shape of a straight line.

  When the box of Patent Document 1 is in a folded state, the force that pushes the front member acting along the linear direction with respect to the side member is supported by the linear side member. It does not act in the direction of folding the member. Therefore, when the box is folded, it is necessary to push and move the front member after folding the side member in the folding direction.

  In order to make the box fully accommodable, it is necessary to extend the side member until it is completely straight. However, some users of the box do not move the front member. May be stopped in the middle of the expansion of the side member, and the stored item may be put in a box that is incompletely accommodated. When an object is put in the incompletely accommodable box, the bottom member rotates in the direction in which the bottom member falls down (the direction in which the container can be completely accommodated) depending on the weight of the object, and the bottom member Then, when the front member is pushed and moved forward, the side member extends linearly and the box can be completely accommodated. For this reason, when the bottom member is rotated by the weight of the storage object, the storage object may be sandwiched between the bottom member, the side member, and the front member.

  An object of the present invention is to deal with such a problem. That is, it is an object of the present invention to enable the switching operation between the folded state and the accommodable state of the box to be performed reliably and quickly.

  In order to achieve the above object, a box according to the present invention has at least the following configuration.

Further, the pulling member 7 has two left and right support pieces 72 provided inside the edge frame 21 of the front member 2 and the operation opening 20 so as to pass through the operation opening 20 in the left-right direction. Is supported by two left and right support pieces 73 provided on the inner side of the peripheral edge 23.

  The support piece 72 is fixed to the upper side of the edge frame 21 so as to have the same height as the left end portion 70 of the pulling member 7 and the fixing portion 74 of the right end portion 71, and the support piece 72 and the left end portion 70 are fixed. The tension member 7 between the right end portion 71 and the fixing portion 74 is supported so as to be inclined in parallel with the ground G and toward the back member 1 (see FIGS. 3 to 5, 7, and 8). The support piece 73 is fixed to the peripheral edge 23 corresponding to the central portion in the vertical direction of the operation hole 20, and supports the pulling member 7 between the support pieces 73 in parallel so as to cross the operation hole 20. At the same time, the tension member 7 between the support piece 73 and the support piece 72 is supported so as to be inclined in the vertical direction (see FIGS. 3 to 5, 7, and 8).

  When the pulling member 7 supported in this manner is pulled down in the operation opening 20, the pulling member 7 positioned between the support piece 72 and the fixing portion 74 is moved with respect to the front folding members 3B and 4B. A pulling force is applied in a direction in which the front member 2 is rotated in a direction approaching the front member 2. Further, the pulling force that rotates the front side folding members 3B and 4B in the direction approaching the front member 2 causes the side members 3 and 4 to be folded inward by the action of the horizontal link mechanism. In addition to being transmitted as a force, it is transmitted as a force for rotating the rear side folding members 3A and 4A in the direction of approaching the back member 1. Simultaneously with the pulling-down operation of the pulling member 7, by applying a force to push the front member 2 in the direction of the back member 1, the side members 3 and 4 are folded by the pushing force and the pulling force. (See FIGS. 4 and 8).

  After the side members 3 and 4 are folded, the bottom member 5 is rotated upward to face the folded side members 3 and 4 and the lid member 6 is rotated downward. The box A is folded by moving the side members 3 and 4 and the bottom member 5 facing each other. In the folded state of the box A, the lid member 6 is held in a directly-facing state with respect to the bottom member 5 by the holding means 9 with respect to the back member 1 and prevents the bottom member 5 from rotating downward. (See FIGS. 2 and 6).

  The urging means 8 is for extending the folded side members 3 and 4 by the urging force so that the box A can be accommodated from the folded state. A spring is used. In the following, the biasing means 8 is referred to as a tension spring 8.

  The tension spring 8 of the present embodiment has one end fixed to the connecting portion 10 and the other end fixed to the rear folding member 41A, and the rear folding member 41A is always outward with respect to the back member 1. It is energized in the direction of rotation. That is, the urging force acting in the direction of rotating the rear side folding member 41A outward with respect to the back member 1 is the force of rotating the side members 3 and 4 in the direction of extending by the action of the horizontal link mechanism. Then, it is transmitted as a force for rotating the front side folding members 3B, 4B with respect to the front member 2, and the side members 3, 4 are automatically extended forward from the folded state (see FIGS. 7 to 9).

  The urging force of the tension spring 8 is weaker than the holding force of the holding means 9 so that the side members 3 and 4 do not extend when the lid member 6 is held. That is, when the lid member 6 is released from the folded state and released upward, the side members 3 and 4 are automatically extended forward by the biasing force of the tension spring 8. The rear side folding member 3A, the front side folding member 3B, the rear side folding member 4A, and the front side folding member 4B are in a linear state. At this time, in the front member 2 that moves forward with the extending side members 3 and 4, the bottom member 5 is pushed and rotated downward to become parallel to the ground G, so that it can be accommodated. A box A is formed. Therefore, the box A of the present embodiment can be automatically made into a box A that can be accommodated by rotating the lid member 6 upward from the folded state.

  The holding means 9 includes the lid member 6, a magnetic body 90 fixed to the back member 1, and a magnet 91 fixed to the lid member 6 and attracting the magnetic body 91 (FIG. 1). FIG. 2). The magnetic body 90 and the magnet 91 are fixed to a portion facing directly in the folded state of the box A. The magnet 91 has a magnetic force (holding force) stronger than the biasing force of the tension spring 8, and the folded state of the box A can be held by the magnet 91.

  As described above, the box A of the present embodiment can be switched between the folded state and the accommodable state, and when the side members 3 and 4 are folded from the accommodable state, the pulling member as described above. It can be folded by pushing the front member 2 in the direction of the back member 1 while lowering 7 downward. Further, by rotating the lid member 6 upward from the folded state, it can be automatically set in the accommodation state as described above. Therefore, the switching operation between the folded state and the accommodable state of the box A can be reliably and quickly performed.

  It should be noted that the present invention is not limited to the illustrated embodiments, and can be implemented with configurations within a range that does not deviate from the contents described in the respective claims.

  In this embodiment, the holding member connected to the connecting portion 10 of the back member 1 so as to be vertically rotatable is also used so that the folded bottom member 5 faces the back member 1. For example, when the folded state of the box body that does not include the lid member 6 as shown in the embodiment is held, for example, a plate-like holding body (such as a plate-like holding body) that faces the sandwiched bottom member 5 with the back member 1 ( It is good also as a structure which connected to the said connection part 10 so that rotation to the up-down direction was possible (not shown). In this case, the magnetic body 90 or the magnet 91 is attached to the holding body (not shown). The mounting position of the magnetic body 90 and the magnet 91 may be opposite to the position shown in the embodiment. Further, in this embodiment, a configuration in which the tension spring is provided only on the side member 4 side is shown, and a configuration in which the magnetic body 90 and the magnet 91 of the holding means 9 are provided only on the side member 3 side is shown. In this invention, it is not restricted to this, You may provide so that it may become contrary to an Example, and you may provide in both the side members 3 and 4 (not shown). Further, in order to reduce the downward rotation speed of the bottom member 5 and relieve shock at a position parallel to the ground G, the bottom member 5 is rotated downwardly across the back member 1 and the bottom member 5. For example, a hydraulic cylinder (not shown) may be provided for slowing the movement. Further, the magnetic member 90 and the magnet 91 in the holding means 9 as shown in the embodiment are provided across the bottom member 5 and the back member 1, and the side members 3 and 4 in which the bottom member 5 is folded and the positive members are provided. In this case, when the lid member 6 is rotated downward during folding, the bottom member 5 can be rotated downward without being supported by the hand. Can be prevented (not shown). The biasing means 8 of the present embodiment is shown as a tension spring.
