Description

[Detailed Description of the Invention] The present invention relates to a device for preventing damage to a collapsible bag for transporting garbage when the bag is folded.

Collapsible bags have been known that are used to load and transport garbage, etc., and are folded and stored when not in use. There was a problem that the X-shaped cross pivots of the side rods that formed the frame got caught and broke.

The present invention has been devised in view of this point, and is designed to prevent damage to the bag body by providing a jamming prevention piece on the X-shaped intersecting pivot portion.

EMBODIMENT OF THE INVENTION Hereinafter, the structure of this invention will be explained about an Example based on drawing.

Figures 1 and 2 show a first embodiment of the present invention, in which 1 is a foldable bag with casters, into which garbage etc. are loaded, and the front frame 2 and the rear frame 3 are attached to both side bars. 4, 4 and 5, 4 are connected at the upper end by horizontal rods 6 and 7 to form a gate shape, and both side rods 4, 4 and 5, 5 are cross-pivoted in an X shape to form a front frame 2. The rear frames 3 are provided so as to be rotatable with respect to each other. The front frame 2 and the rear part 3 are bent at the lower portions of the rods 4, 4 and 5, 5 on both sides, and shaft rods 8 and 9 are provided at the bent portions across the rods 4, 4 and 5, 5 on both sides. Two parallel connecting rods 10 and 11 project inward from the rods 8 and 9, respectively, and the connecting rods 10 and 11 are connected and fixed in a straight line by lashing means. The lashing means is for elastically connecting the lower part of the front frame 2 and the rear frame 2.
The connecting rod 10 has three engaging shafts 12, 12, 12.
are provided at regular intervals, and the connecting rod 11 of the rear frame 3 has three concave engagement holes 13, 13, 13 at the bottom that can be engaged with the engagement shafts 12, 12, 12.
The three engagement holes 13, 13, 13 are provided at the same spacing as the spacing between the engagement shafts 12, 12, 12, and are selectively engaged with the engagement shafts 12, 12, 12. Ru. Further, a fixing plate 14 having both ends bent into a U-shape is slidably provided on the connecting rod 10 of the front frame 2, and the fixing plate 14 is attached to the engaging shafts 12, 12,
12 and the engagement holes 13, 13, 13 are slidably fitted to the connecting rod 11 of the rear frame 3. At the lower ends of the front frame 2 and rear frame 3, casters 15, 15, 15,
15 is rotatably provided, and a bag body 17 having an opening at the top is suspended from both horizontal rods 6 and 7. Reference numeral 18 denotes a disc-shaped bag-inclusion prevention piece attached to the side bars 4 and 5 at the intersecting pivot point of the side bars 4 and 5, and 19 is a handle attached to the side bar 6. be.

Next, a second embodiment of the present invention will be explained with reference to FIG. 3. This second embodiment is similar to the disk 1 of the first embodiment.
8, a fan-shaped plate 20 is fixed to one of the side frames 4 and 5. The other configurations are completely the same as the first embodiment.

Next, to explain the function of the present invention, the front frame 3
Then, the rear frame 4 is opened and set as shown in FIG. 1, and garbage and the like are loaded into the bag body 17 and transported. Next, when folding it when not in use, slide the fixing plate 14 to the left and
2 and the engagement hole 13, and then open the front frame 3.
Then, the rear frame 4 is rotated around its X-shaped cross pivot and folded into the position shown in FIG. 2. At this time, a part of the bag body 17 will be caught in the X-shaped cross pivot However, since the disc-shaped bag-entanglement prevention piece 18 prevents the bag from entering the intersection pivot, the bag 17 will not be caught in the intersection and damaged. In the second embodiment shown in FIG. 3 as well, the fan-shaped bag jamming prevention piece 20 prevents the bag from entering the intersection pivot, so that damage to the bag during folding can be prevented.

As explained above, according to the present invention, the bag can be used for a long period of time because damage to the bag can be prevented during folding. Further, in the first embodiment, the disk 1
If 8 is made of a resin material, wear between the side bars 4 and 5 can be prevented, and the rotation of the front frame 3 and the rear frame 4 can be made smooth and easy.
