On the storage side (opposite to the outer flat surface), an opening having a shape corresponding to the shape of the peripheral edge of the frame member 131 is provided. Casters 105 are provided on the left and right of the bottom wall of the right main body 101. The caster 105 may be a known one and is not limited to the one shown in the figure.

Between the edge of the top wall, the side wall and the bottom wall of the right main body 101 and the edge of the frame 103, a hinge-type telescopic mechanism 1 is provided. Specifically, the upper expansion and contraction mechanism 1 provided between the upper wall of the right main body 101 and the upper frame of the frame member 131 has two plate bodies 2 arranged side by side, and these plate bodies 2 are It is rotatably connected by a rotating shaft 3 provided at the end edge. More specifically, the end edge of the plate 2 is formed into a tubular shape, and the concave and convex portions fitted in the tubular portion are formed in the direction of the end edge, and the tubular portion similarly formed on the end edge of the adjacent plate 2 The cylindrical portions of both plates 2 are aligned in a straight line in the direction of the end edge, and a metal bar is inserted through the cylindrical portions to form a connection structure. The plate 2 and the plate 2 may be connected by a plurality of commercially available hinges or long hinges, and the rotary shaft 3 of the hinge may be configured as the rotary shaft 3 (not shown).

The edge of the right side plate 2 and the edge of the upper wall of the right main body 101 are flexibly and rotatably connected by the fastener 4 as described above. The end edge of the left plate 2 and the end edge of the upper frame of the frame member 131 are similarly flexibly rotatably connected by the fastener 4. The rotating shaft 3 and the fastener 4 are parallel to the end edge of the right main body 101 and the end edge of the frame 103 in order to expand and contract the right main body 101 with respect to the frame 103. The plate 2 uses a highly rigid non-flexible material such as aluminum, reinforced plastic, carbon fiber or the like. The thickness of the plate 2 is set to a thickness that can obtain inflexibility, and is appropriately determined depending on the material.

Also between the bottom wall of the right main body 101 and the bottom frame of the frame member 131, the bottom telescopic mechanism 1 of the same structure is provided by the same connection structure as described above. Between the side wall of the right main body 101 and the side frame of the frame member 131, the side extension and contraction mechanism 1 having the same structure is provided by the same connection structure as described above.

Each plate 2 has a strip shape, and the short side is inclined. The long side on the side connecting the plate members 2 is shorter than the long side on the side connecting the plate member 2 to the frame 103 and the right main body 101. When the two plates 2 are open, the short side is in the shape of "」 ".

A corner extension mechanism 5 is provided between the upper wall corner of the right main body 101 and the upper frame corner of the frame 103 which is a corner portion of the upper extension mechanism 1 and the side extension mechanism 1. The corner expansion and contraction mechanism 5 has two square plate bodies 51 of trapezoidal shape arranged in parallel, and the square plate bodies 51 are connected rotatably by a rotation shaft 52 provided at an end edge of the square plate body 51. . Further, the end edge of the right rectangular plate body 51 and the end edge of the upper wall corner of the right main body 101 are also rotatably connected by the fastener 53 in the same manner as described above. The edge of the left side plate 2 and the edge of the upper frame corner of the frame 103 are also rotatably connected by the rotation shaft 52 in the same manner as described above. The corner stretchable mechanism 5 is provided at the four corners of the right main body 101 of the bag 100.

Further, a flexible protective cloth 55 is provided in a gap formed between the rectangular plate 51 and the plate 2. At the time of expansion, the protective cloth 55 spreads to protect the gap. At the time of folding, the protective cloth 55 is folded by being driven by the plate 2 and the rectangular plate 51. The corner expansion and contraction mechanism 5 may be configured so as to cover only the cloth having strength by omitting the square plate 51 and the like (the same as in the following second to fourth embodiments).

A covering layer of a stretchable material such as cloth may be provided on the expanded portion of the stretch mechanism 1. Also, the right main body 101 and the frame member 131 may be connected by a known catch lock or the like other than the fastener 4 (not shown).

A telescopic handle mechanism 108 used at the time of pulling is provided on the flat surface side of the right main body 101. The handle mechanism 108 can adopt a known structure, and is not limited to the one shown in the figure.

The left main body 102 has the same structure as the right main body 101 with the frame 103 being symmetrical. The handle mechanism 108 used at the time of pulling is not provided.

Next, the operation of the bag 100 will be described. In the normal state, the right main body 101 and the left main body 102 are connected to the frame member 131 by fasteners, and the plate 2 and the square plate 51 are folded inside the bag 100. The plate 2 and the square plate 51 are folded so as to protrude to the inside of the bag 100 and protrude from the end edge of the frame member 131 to the inside of the bag 100. The projecting direction is substantially parallel to the flat portion of the bag 100. Therefore, the plate 2 and the square plate 51 function as a partition between the right main body 101 and the left main body 102 and the frame member 131, so that the contents go out when the right main body 101 or the left main body 102 is opened. To prevent The larger the width of the plate 2 and the rectangular plate 51, the higher the function as a partition. Further, since the plate body 2 and the square plate body 51 are supported by the rotary shaft 3, they swing in a flap shape in a folded state. For this reason, it is convenient when packing luggage, and also has a function of holding down and securing the luggage.

When the bag 100 is expanded, the fastener 4 is opened to separate the right main body 101 or the left main body 102 from the frame member 131, and the right main body 101 or the left main body 102 is pulled out. Thereby, the plate body 2 and the square plate body 51 open centering on the rotating shaft 3, the right main body 101 or the left main body 102 is extended, and the right or left capacity of the bag 100 is expanded. The plate 2 is connected to the end edges of the right main body 101 and the left main body 102 by the fasteners 4 and therefore does not deform in the bending direction. Moreover, the said board 2 functions as a reinforcing material, and prevents bending and a twist. That is, the bag 100 expands in a state in which the rigidity is maintained by the expansion and contraction structure. Therefore, even when the bag 100 is erected by the caster 105, the entire bag 100 is not deformed, so that it can be handled stably.

In order to open the bag 100, the lock mechanism 107 of the frame 103 is removed, and the lock mechanism 107 of the frame 103 is opened to the left and right around a hinge provided on the frame 103. Thereby, the frame member 131 connected to the right main body 101 or the left main body 102 is separated and opened from the frame 103, and the right main body 101 or the left main body 102 is opened. When the right main body 101 or the left main body 102 is not expanded, the stored matter does not spill out because the plate 2 and the square plate 51 project inward with the bag 100 opened. When the right main body 101 or the left main body 102 is expanded, the sheet 2 does not protrude in the state where the bag 100 is opened, but since the depth of the right main body 101 or the left main body 102 can be secured, the stored matter does not spill out.

When the bag 100 is closed, the right body 101 or the left body 102 is closed about the hinge, and the frame 103 and the frame member 131 are locked by the lock mechanism 107.

In addition, connection of the plate 2 with each other, the plate 2 and the right main body 101 or the left main body 102, and the plate 2 and the frame member 131 can be performed not by the above fastener but by a rotational shaft or thick cloth (not shown) ). That is, since the end edges are connected by the rotation axis or the cloth, the plates 2, the plate 2, the right main body 101, the left main body 102, and the frame member 131 can be rotated. Further, a torsion coil spring is passed through the mandrels of the plate 2 and the rotary shaft 3 and an arm extending outward from the torsion coil spring is fixed to the plate 2 so that the plates 2 are opened by the torsion coil spring. You may be urged to. In this way, when the right main body 101 or the left main body 102 is removed from the frame 103 and expanded, the right main body 101 or the left main body 102 is urged to move automatically, so the right main body 101 or the left main body This makes it easy to expand 102 (same as in the following second to fourth embodiments).

Second Embodiment
FIG. 6 is a side view showing a bag according to Embodiment 2 of the present invention, and shows an expanded state. FIG. 7 is a top view of the bag shown in FIG. 6 in an expanded state. FIG. 8 is a plan view showing the telescopic mechanism and shows the longer configuration (the shorter configuration is also the same). The bag 200 according to the second embodiment is characterized in that the expansion and contraction mechanism 1 of the bag 100 according to the first embodiment is formed in a bellows shape, and the structure of the other right main body 101, left main body 102 and frame 103 Is the same as the bag 100 of the first embodiment, and therefore the description thereof is omitted.

The four plates 202 constituting the expansion and contraction mechanism 201 are strip-shaped, and the respective plates 202 are connected by the rotating shaft 3. The plates 202 on both sides of the extension mechanism 201 are connected to the right main body 101 and the left main body 102 by the rotation shaft 3. The configuration of the rotary shaft 3 is the same as that of the first embodiment. In addition, a strip-like mounting plate 203 is provided at the end of the expansion and contraction mechanism 201 via the rotation shaft 3 as it is connected by the rotation shaft 3, and the mounting plate 203 is bolted to the right main body 101 and the left main body 102. It is fixed.

By expanding and contracting in a bellows-like manner by the four plates 202, the portion projecting inside of the bag 200 in the folded state of the plate 202 becomes smaller than that of the bag 100 of the first embodiment. Similarly to the plate 202, the square plate 251 is also composed of four sheets, and the square plates 251 are connected by the rotation shaft 52. The rectangular plate body 251 is trapezoidal, and the side projecting to the inside of the bag 200 is the short side.

As described above, according to the bellows-like expansion and contraction mechanism 201, the expansion amount can be increased, and the portion in which the plate 202 and the rectangular plate 251 protrude inside can be reduced. In addition, it has the same effect as the bag 100 of the first embodiment.

Third Embodiment
FIG. 9 is a side view showing a bag according to Embodiment 3 of the present invention and shows an expanded state. FIG. 10 is a top view of the bag shown in FIG. 9 in an expanded state. FIG. 11 is a side view of the bag shown in FIG. 9 shown closed. FIG. 12 is a top view of the bag shown in FIG. 9 shown closed. FIG. 13 is a cross-sectional view of the bag shown in FIG. The bag 300 has substantially the same configuration as that of the first embodiment, but differs in that the bag 300 is opened and closed with a fastener instead of the locking mechanism 107. That is, the fastener 304 is provided at the edge of the

frame members

301 and 302 constituting the frame, and can be opened at any position.

Further, a lock mechanism 307 is provided on the upper portion of the left main body 102. The slider handle 305 of the fastener 304 is fixed by the locking mechanism 307. The lock mechanism 307 is provided with a hole into which the handle 305 is inserted, and a hook that slides inside the housing is provided in the hole. The hook is opened and closed by the buttons on both sides of the case, and the key on the upper part of the case regulates the operation of the button. By inserting the handles 305 of the two sliders into the holes and locking them with the lock mechanism 307, it is possible to lock the opening and closing of the right main body 101 and the left main body 102. The lock mechanism 307 and the handle 305 can adopt known structures.

Furthermore, in the bag 100, the lock mechanism 107 is provided on the side of the frame 103 on the surface of the plate 2 provided on the upper portion of the left main body 102, and the plate 2 on the left main body 102 is folded. A relief hole 310 is provided to escape through. That is, in the state where the left main body 102 is not expanded, the lock mechanism 107 enters the escape hole 310 provided in the overlapping plate 2 in the folded state and is exposed inside the left main body 102. When the left main body 102 is expanded, the lock mechanism 107 appears on the plate 2. Then, the knob is positioned at the upper part of the bag 100, attached to the lock mechanism 107, and locked.

In this way, locking of the bag 100 is possible both when the bag 100 is unexpanded and when expanded. In addition, since the lock mechanism 107 provided on the upper portion of the left main body 102 becomes unused when the bag 100 is expanded, an optional one may be attached.

In addition, the opening and closing of the bag 100 of the second embodiment may be performed with a fastener like the bag 100 of the third embodiment (not shown).

Embodiment 4
Further, as shown in FIGS. 14 and 15, a fastener 109 may be used in place of the lock mechanism 107 of the frame 103 of the first embodiment. That is, the bag 100 has a structure in which the right main body 101 and the left main body 102 are provided on the left and right of the frame 103. The frame 103 is provided with fasteners 109 at both ends, and is connected to the plate 2 of the expansion and contraction mechanism 1 by the fasteners 109. Therefore, by opening the fastener 109, the right main body 101 and the left main body 102 can be opened. The slider handle 110 of the fastener 109 is fixed by the locking mechanism 107. As described above, the lock mechanism 107 is provided with a hole into which the handle 110 is inserted, and a hook that slides inside the housing is provided in the hole. The hook is opened and closed by the buttons on both sides of the case, and the key on the upper part of the case regulates the operation of the button. By inserting the handles 110 of the two sliders into the holes and locking them with the lock mechanism 107, it is possible to lock the opening and closing of the right main body 101 and the left main body 102.

The other configuration is the same as that of the bag 100 of the first embodiment, and therefore the description thereof is omitted, and the same components are denoted by the same reference numerals. In this bag 400, since the right main body 101 and the left main body 102 are connected to the left and right of the frame 103 by the fasteners 109, higher strength can be obtained than in the second embodiment where the telescopic mechanisms 1 are connected by the fasteners 304.
