The movable container according to claim 1, further comprising a rotation fixing mechanism a set at a position fixed at the end point.

[0006]

BEST MODE FOR CARRYING OUT THE INVENTION A preferred embodiment of the present invention (how to carry out the invention) will be briefly described with reference to the drawings and showing its function and effect.

[Invention 1] When the shelf plate 8 is folded in two and is extended vertically from a state where it is held vertically, the engaging portion 8'of the shelf plate 8 causes the lateral crosspieces of the side frames 5.6 to be supported. The shelf plate 8 is fixed in a horizontal state by engaging with 5'and 6 '.

Therefore, it is convenient that the luggage can be loaded vertically separately.

If the shelf 8 is not desired, the shelf 8
Is folded in two by a hinge 7 and pulled up to fit the back frame 3, and the holding plate 9 is pivotally fixed to a position along the back frame 3 by a pivot fixing mechanism a, so that the shelf plate 8 is attached to the folded back frame 3. It is held in the standing position, and is prevented from falling down without permission.

Further, the holding plate 9 is fixed by the rotation fixing mechanism a.
When the holding plate 9 is moved to a position along one of the side frames 5 by rotating outwardly by 0 °, the shelf plate 8 can be laid down in a horizontal state, and the locking portion 8 ′ has the side frame 5 6 support rails 5 '
・ Locked to 6'and fixed horizontally.

[Invention of Claim 2] The rotation fixing mechanism a has a space between the notch long grooves 12 and 13 provided at two positions of the rotation cylinder 11 provided at the base of the holding plate 9 and one side frame 5. Since the position of the fixed rod 14 attached to the provided back side vertical pipe 10 is set to the position where the holding plate 9 is fixed at the initial point and the end point of 90 ° rotation, the rotary cylinder 11 is lifted and the fixed rod 14 is fixed. When removed from either one of the notch long grooves 12 and 13, the rotating cylinder 11 becomes rotatable, so that the holding plate 9 is held in a predetermined shelf plate holding state by re-fitting to the adjacent one of the notch long grooves 12 and 13. It is possible to rotate 90 degrees from the position to the position where the shelf board can be laid down, and the reverse rotation can be similarly fixed at the predetermined start point and end point positions.

Embodiments of the present invention will be described with reference to the drawings.

A bottom frame 4 with casters 2 provided with a bottom plate 1
In a movable container in which a back frame 3 and left and right side frames 5 and 6 are arranged upright in a planar channel shape, a shelf 8 which can be folded in half by a hinge 7 in the middle of the height of the back frame 3 The back side of the shelf 8 is rotatably and rotatably provided with respect to the horizontal rail 3'of the back frame 3 so that the stand can be erected from a horizontal state to a vertical state. The support rails 5'and 6'of 5.6 are provided so that the locking portions 8'provided on the shelf plate 8 can be locked and fixed, and when the shelf plate 8 is folded in two and pulled up in the vertical state, The holding plate 9 that holds the state is rotated 90 degrees outward from the position where the shelf plate 8 is held by one of the left and right side vertical pipes 10 of the left and right side frames 5 and 6 so as to follow the one side frame 5. It is movably provided, and the holding plate 9 is provided at the starting point and the ending point of this 90-degree rotation.
The holding plate 9 is provided with a rotation fixing mechanism a for fixing the
And a movable container provided on the back side vertical pipe 10.

The movable container shown in the figure is formed so that the bottom plate 1 can be held vertically and can be locked, and the back frame 3 and the side frames 5
6 is provided so that one or both side frames 5 and 6 can be folded into the back frame 3 by a connector 17 having bearing portions 16 at both ends.
When storing it, make it a hook type or double type so that it does not take up space.

In the figure, reference numeral 15 is a washer for restricting the pulling-up position of the rotary cylinder 11, 18 is a shaft mounting piece, 19 is a bearing piece, and 20 is a shaft pin, and the shelf plate 8 is provided so as to be up and down.

A rotary cylinder 11 attached to the base of the holding plate 9 is fitted on the back side vertical pipe 10 of one side frame 5 so as to be rotatable and vertically movable. Notched long grooves 12 and 13 are provided at two locations with a predetermined interval facing upward, and these notched long grooves 12 and 13
A fixing rod 14 that fits in and engages with 13 is vertically provided on the outer peripheral surface of the back side vertical tube 10, and the position of the fixing rod 14 and the notch long groove 12, 13 is the starting point of the holding plate 9 rotating 90 degrees. The movable container according to claim 1, further comprising a rotation fixing mechanism a set at a position fixed at the end point.

In the figure, the locking portion 8'is vertically provided on the side surface of the front shelf plate 8, and the supporting horizontal rails 5'and 6'are erected in a protruding state slightly inward from the original horizontal rail position and locked. To be good.

[0018]

Since the present invention is constructed as described above, when the shelf board is held vertically, the shelf board is horizontally tilted so that the locking parts of the shelf board are locked to the supporting cross rails of the side frame. Fix the plate horizontally. Therefore, it is convenient to be able to load the luggage separately.

When it is not desired to use the shelf board, the shelf board is folded in two by a hinge and pulled up to fit the back frame, and the holding plate is pivotally fixed to a position along the back frame by the rotary fixing mechanism. The board holds the standing state along with the bi-fold back frame,
Prevents probation.

Further, by rotating the holding plate 90 degrees outward by the rotation fixing mechanism and moving it to a position along one of the side frames, the shelf plate can be laid down in a horizontal state, and the above-mentioned locking portion. It is a movable container that is excellent in practicality, such as being locked to the horizontal rail of the side frame and fixed in a horizontal state.

Further, in the invention according to claim 2, in the rotation fixing mechanism, the fixed rod is fitted into and locked in the notch long groove by the distance between the notch long grooves provided at two places of the rotating cylinder provided at the base of the holding plate. By doing so, the holding plate is set at a position where it is fixed at the initial point and the end point of 90-degree rotation. Therefore, if the rotary cylinder is lifted and the fixing rod is removed from the notch long groove, the rotary cylinder becomes rotatable. By refitting into the notch long groove, the holding plate can be rotated 90 degrees from a predetermined shelf plate holding state position to a position where the shelf plate can be collapsed. It becomes a movable type container with excellent practicality such as fixing the end point position.
