Description

The frame members 20 and 21 are integrated in a state of being connected to each other and facing each other between the leg portions 20b and 21b and between the cross-linking portions 20c and 21c. Fixed joints 40a, 40a (41a, 41a) are attached to the legs 20b, 20b (21b, 21b) of each frame member 20 (21) at upper positions, and the joints 40a, 40a ( Movable joints 40b, 40b (41b, 41b) are attached to the lower portions of 41a, 41a), respectively. The fixed joint 40a (41a) of one frame member 20 (21) and the movable joint 41b (40b) of the other frame member 21 (20) are connected via cross frames 43 and 44, respectively. These cross frames 43 and 44 are rotatable with respect to the joints 40a, 40b, 41a and 41b to which they are connected. Further, the cross-linking portions 20c and 21c of the frame members 20 and 21 are connected to the base end portions of the plate-shaped members 20d and 21d extending toward the other cross-linking portions 21c and 20c so as to face each other. The plate-shaped members 20d and 21d are rotatable with respect to the crosslinked members 20c and 21c. The tip portions of the plate-shaped members 20d and 21d facing each other are also connected to each other, and the plate-shaped members 20d and 21d are also rotatable to each other.

In the cart main body 2 configured in this way, the frame members 20 and 21 arranged to face each other can be brought close to each other and separated from each other. In the state where the frame members 20 and 21 are most separated from each other, the plate-shaped members 20d and 21d are linearly connected to each other, but the frame members 20 and 21 are bent while the connecting portions of the plate-shaped members 20d and 21d are bent. The frame members 20 and 21 can be easily brought close to each other by applying a force that brings them close to each other. At this time, the plate-shaped members 20d and 21d rotate around the bridged portions 20c and 21c to which they are connected as fulcrums, and the distance between the bridged portions 20c and 21c becomes smaller. Further, the movable joints 40b and 41b move downward, and the cross frames 43 and 44 rotate with respect to the joints 40a, 40b, 41a and 41b, so that the distance between the legs 20b and 21b is reached. is corresponds to be smaller. As described above, in the cart main body 2, the frame members 20 and 21 can be separated from each other in close proximity to each other. Therefore, when the cart main body 2 (transport cart 1) is not used, the frame members 20 and 21 are separated from each other. It can be stored in close proximity and not bulky.

As shown well in FIG. 1, the housing body 3 has a bottomed bag shape or a box shape with an opening at the top, and a bag body such as a plastic bag, which will be described later, is housed in the peripheral portion of the opening. holding means 4 for holding the body 3 is eclipsed total of four set on the inner surface side of the container 3. That is, the housing 3 has a shape in which the bottom portion of the tubular portion having a rectangular cross section composed of the first to fourth side surfaces 30a to 30c is closed by the bottom surface 30e. As better shown in FIG. 3, the first side surface 30a and the second side surface 30b are opposed to each other, and the bottom surface 30e is constituted by a first sheet material 30A that is a single cloth, the opposing The third side surface 30c and the fourth side surface 30d are composed of the second sheet material 30B and the third sheet material 30C, respectively. The sheet materials 30A to 30C are formed of, for example, a non-woven fabric made of resin, and the sheet materials 30A to 30C are connected by means such as sewing to form the accommodating body 3. As the housing body 3, it is also possible to adopt a housing body 3 in which a lid capable of closing the upper opening is integrally formed.

In the present embodiment, the upper edge edges of the second sheet material 30B and the third sheet material 30C are sewn and rimmed with the edging cloths 31B and 31C, and the holding means 4 are sewn and fixed together with the edging cloths 31B and 31C. The side edges and lower edges of the second and third sheet materials 30B and 30C are connected to the side edges of the first sheet material 30A by sewing. The longitudinal dimension of the first sheet material 30A is larger than the total length of both side edges and the lower edge of the second and third sheet materials, and both ends of the first sheet material 30A in the longitudinal direction. The sheet materials 30A, 30B, and 30C are connected to each other so that the portions protrude. The portion where the first sheet material 30A protrudes is a folding margin 32, 32 used when the accommodating body 3 is attached to the cart main body 2. That is, as is clearly shown in FIG. 1, the housing body 3 has the frame members 20 and 21 respectively due to the folding margins 32 and 32 of the first sheet material 30A (first and second side surfaces 30a and 30b). It is held in the cart body 2 in a manner that wraps the horizontal portions 20a and 21a of the above. The state in which the horizontal portions 20a and 21a are wrapped by the folding margins 32 and 32 is well maintained by the hook-and-loop fasteners 33 and 33.

As shown well in FIG. 1, each of the holding means 4 is provided with two each on the upper edges of the third and fourth side surfaces 30c and 30d, and each holding means 4 is provided with the housing body 3. It is provided on the inner surface side of. As shown in FIGS. 4 and 5, these holding means 4 have a pair of spatula portions 4A and 4B whose tip portions are free ends, respectively. A male hook 4a as a male portion is provided on the tip end side of one of the spatula portions 4A and 4B, and as a female portion on the tip end portion side of the other spatula portion 4B. Female hook 4b is provided. That is, by fitting the male hook 4a to the female hook 4b, the tip portions of the spatula portions 4A and 4B are connected to each other. Each of the above-mentioned spatula portions 4A and 4B has a free end portion thereof, for example, by fixing the folded-back portion 40A of the long-shaped cloth 40. As described above, each of the holding means 4, third or fourth aspect 30c, second or third sheet member 30B constituting 30d, edging for fiber 31B bordering the upper edge of 30C, is sewn fixed with 31C ing. That is, as clearly shown in Figure 5, the folded portion 40A of the elongated fabric 40 is interposed between the border for fiber 31A (31B) and the sheet material 30B (30C), edging for fiber 31A in this state Together with (31B), it is sewn and fixed to the upper edge edge of the sheet material 30B (30C). The male hook 4a is removable and detachable with respect to the female hook 4b, and a known male-female fitting type hook is adopted as the male part and the female part.

The transport cart 1 having the configuration described above is used, for example, when collecting garbage in an office building or the like, or when collecting and transporting towels, sheets and the like in a facility such as a hotel. That is, dust, towels, sheets, and the like are stored inside the container 3, and the cart body 2 is moved together with the container 3 to transport the dust and the like. When collecting dust or the like, FIGS. 6 and 7 show the inside of the housing 3 so that the inside of the housing 3 is not contaminated by dust or the like, or for convenience when handling the collected dust or the like. As described above, the bag body 6 such as a plastic bag is housed and held inside the container body 3 in an open state. Then, dust and the like are substantially stored inside the bag body 6.

FIG. 12
It is sectional drawing which follows the XII-XII line of FIG.
