Abstract

PROBLEM TO BE SOLVED: To provide a bag with storable casters having a simple configuration and capable of changing over casters between a moving state where the casters are projected from a bag bottom part, and a storage state where the casters are stored in a storage part.SOLUTION: The bag with storable casters includes: fixing caster storage parts with opening/closing lids to corners of a bottom part of the bag; journaling a caster holding part to each caster storage part so as to be rotationally turned about a horizontal shaft disposed in the caster storage part; rotationally holding a caster frame to the caster holding part, rotatably journaling a caster to an axle fixed to the caster frame; opening the opening/closing lid of the caster storage part; rotating the caster holding part 90 degrees to project the caster from the caster storage part and make it movable; and inversely rotating the caster holding part to store the caster in the caster storage part.SELECTED DRAWING: Figure 5

Description

  The present invention relates to a bag with casters, and more particularly to a bag with casters that can be stored.

  Conventionally, the caster of the bag with a caster is a form fixed to the bottom of the bag.

JP 2001-87023 A

  Since the caster is fixed to the bottom of the bag, the caster is always exposed, dirt on the move is attached to the caster and the appearance is not good, and it moves if the bag with casters is not held in the train etc. Have the problem of

  The present invention provides a bag with a storable caster that solves the problems of the prior art, has a simple structure, allows the caster to protrude from the bottom of the bag, and allows the caster to be stored in the storage unit. With the goal.

  In order to solve the above problems, the bag with stowable caster of the present invention has a caster storage portion with an opening / closing lid fixed to a corner at the bottom of the bag, and a caster holding portion is disposed in the caster storage portion in the caster storage portion. The caster frame is pivotally supported on the horizontal axis, the caster frame is rotatably held on the caster holding part, the caster is pivotally supported on the axle fixed to the caster frame, the opening / closing lid of the caster storage part is opened, and the caster The holding part is rotated 90 degrees to allow the caster to protrude from the caster storage part to be movable, and the caster holding part is rotated in the reverse direction to place the caster in the caster storage part.

  The bag with a stowable caster according to the present invention is a latch means for preventing rotation of the caster holding part about the horizontal axis when the caster holding part is rotated 90 degrees about the horizontal axis and the caster is protruded from the caster storage part. Is provided in a caster storage portion, and a latch release means for releasing the latch means is disposed outside the caster storage portion.

  In addition, the bag with a stowable caster of the present invention is provided with an opening / closing lid that opens and closes the bottom opening of the caster housing part excluding the projecting opening of the caster via a hinge means, and is closed when the caster is stowed and when the caster projects. It is possible to make it possible.

A caster storage part with an open / close lid is fixed to the corner of the bottom of the bag, a caster holding part is pivotally supported on a horizontal axis disposed in the caster storage part, and a caster frame is attached to the caster holding part. The caster is rotatably supported on the axle fixed to the caster frame, and the caster storage part is opened. The lid of the caster storage part is opened, the caster support part is rotated 90 degrees, and the caster protrudes from the caster storage part. By turning the caster holding part in the reverse direction and putting the caster in the caster storage part, the caster protrudes from the caster storage part and can be moved, and the caster is moved to the caster storage part. It becomes possible to carry out with a simple operation in the stored state.
When the caster holding part is rotated 90 degrees about the horizontal axis and the caster is protruded from the caster storage part, a latch means for preventing the rotation of the caster holding part about the horizontal axis as an axis is provided in the caster storage part. By disposing the latch release means for releasing the latch means, the caster can stably travel when it is in the moving state by protruding from the storage portion.
An open / close lid that opens and closes the bottom opening of the caster storage section excluding the caster projection opening is attached via a hinge means, allowing it to be closed when the caster is stored and when the caster protrudes. Since the lid is in a closed state, it is possible to smoothly perform the movement by the casters.

  Embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a schematic diagram illustrating a state in which casters are stored in a storage unit disposed in a corner at the bottom of the bag, and FIG. 2 is a schematic diagram illustrating a state in which the casters protrude from the storage unit.

  A handle 2 is attached to the bag 1. A caster storage portion 3 is fixed to a corner at the bottom of the bag 1.

  FIG. 3 is a longitudinal sectional view of the caster storage unit 3, and FIG. 4 is a bottom view of the caster storage unit 3 with the opening / closing lid 4 opened.

  The opening / closing lid 4 can be freely opened and closed via a hinge 5 leaving a caster protruding opening at the bottom opening of the caster housing 3. Elastic locking means 6 is attached to the opening / closing lid 4 to keep the opening / closing lid 4 closed.

  A horizontal shaft 7 is disposed in the caster storage unit 3 with both ends thereof fixed to the caster storage unit 3. A caster holding member 8 is rotatably supported on the horizontal shaft 7. A caster frame 9 is rotatably disposed on the caster holding member 8 via a bearing 10. The caster frame 9 is secured with a stopper 11 for the caster holding member 8.

  A caster 13 is rotatably supported on an axle 12 fixed to the caster frame 9. The caster storage unit 3 is provided with latch means 14 that latches the rotation of the caster holding unit 8 around the horizontal shaft 7. A latch releasing means 15 for releasing the latch means 14 is disposed outside the caster housing 3. The latch means 14 does not act when the caster 13 is located in the caster storage 3.

  As shown in FIG. 4, the open / close lid 4 of the caster storage unit 3 is opened. As shown in FIG. 5, when the caster 13 is lifted up, the caster holding member 8 rotates 90 degrees about the horizontal shaft 7, and the caster 13 protrudes from the caster storage portion 3. When the caster holding member 8 is rotated 90 degrees about the horizontal axis 7, the latch means 14 disposed in the caster storage portion 3 is latched to rotate about the horizontal axis 7 of the caster holding member 8.

  As shown in FIG. 5, when the caster 13 protrudes from the caster housing 3, the opening / closing lid 4 is closed, so that the opening / closing lid 4 does not obstruct the running of the caster 13. Since the rotation of the caster holding member 8 around the horizontal axis 7 is latched, the caster 13 can move and travel stably. Further, since the caster frame 9 is made rotatable by the caster holding member 8 via the bearing 10, the direction change by the caster 13 can be easily performed.

  A procedure for storing the caster 13 in the caster storage unit 3 from a state where the caster 13 protrudes from the caster storage unit 3 will be described. First, the opening / closing lid 4 is opened. Next, the latch release means 15 disposed outside the caster storage portion 3 is operated to release the latch means that latches the rotation of the caster holding member 8 around the horizontal axis 7. Holding the caster 13, the caster 13 is rotated 90 degrees in the direction opposite to that when the caster 13 protrudes, and the caster 13 is positioned in the caster storage unit 3. The opening / closing lid 4 is in the state shown in FIG.

  As described above, the bag with a stowable caster according to the present invention has a simple configuration and can be carried out by a simple operation in a state in which the caster protrudes from the caster storage portion and can be moved and in a state in which the caster is stowed in the caster storage portion. Is possible.
