Description

  According to the present invention, a pair of intersecting frames, each having a substantially central portion that is pivotally supported by a hinge shaft and configured to be foldable, are connected and arranged at a predetermined interval, and four corners of an opening of the garbage bag are formed at the upper end of each intersecting frame. The present invention relates to a foldable trash separation bin configured to be locked.

As in recent years, when the eating habits are enriched and a large amount of goods are overflowing, not only homes but also various business establishments, highway service areas, hospitals, railway station buildings, etc. A large amount of waste is released, causing problems such as global environmental degradation and resource depletion. For this reason, separate collection of garbage is a particularly important issue for each region. In particular, facilities such as small-scale stores and private households that do not allow a large amount of money and space to be used in the recycle bin have become difficult to deal with various types of garbage as in recent years. In individual homes, as well as in event sites such as construction sites, camps, and athletic events, folding type waste bins that are easy to install and remove are desired. On the other hand, plastic bags distributed at supermarkets and convenience stores are widely used as garbage bags that are inexpensive and can be used easily. At present, many of these garbage bags are prepared to deal with different types of garbage. A foldable garbage bag holder has been proposed as one that can easily hold these soft plastic bags and the like (see, for example, Patent Document 1 below).

The connecting plates 35 to 38 are detachable from the ends of the support columns 31 and 32, and the pair of frames 34 and the four connecting plates 35 to 38 are engaged and assembled. A lid body 45 capable of displaying characters, figures, patterns and the like covering the opening C1 of the garbage bag C is suspended from the upper connecting plate 35. The frame 34, the connecting plates 35 to 38, and the lid 45 are made of environmentally friendly materials.

  With such a configuration, the lid body 45 is provided by a flexible material capable of displaying characters and the like, so that the dust inside the garbage bag C can be seen from the surroundings by covering the opening of the garbage bag C. There is no damage to the landscape. Further, it is possible to prevent the dust in the garbage bag C from being blown off by wind or the like, and it is possible to enhance the function as a folding garbage bag holder. However, although the conventional garbage bag holder shown in FIG. 4 is inexpensive and simple, it is not sufficient for separating many kinds of garbage, and it is unstable and easily moved in the folding direction. Met.

  Therefore, in the present invention, the problem of the conventional folding separation bin can be solved, a stable shape can be maintained as a folding bin, and a large number of waste bins can be juxtaposed and stacked to facilitate separation of waste. The purpose is to provide a collapsible trash bin.

  According to the present invention, a pair of intersecting frames, each having a substantially central portion that is pivotally supported by a hinge shaft and configured to be foldable, are connected and arranged at a predetermined interval, and four corners of an opening of the garbage bag are formed at the upper end of each intersecting frame. In the collapsible trash separation bin configured to be locked, a box-like stacking attachment having a trash input port opened on a side surface is placed on an upper end portion of each cross frame. In the present invention, a stacking projection is formed at the upper end of each cross frame, a stacking groove is formed at a portion corresponding to the stack projection at the bottom of the stack attachment, and the end of each cross frame is further formed. A connecting portion is formed on the side surface in the vicinity. Further, the present invention is characterized in that a stacking groove is formed at a lower end portion of each cross frame. Further, the present invention forms stacking projections at the four corners of the top plate of the stacking attachment, and locks the stacking grooves at the lower end of each cross frame to these stacking projections, A plurality of trash cans are stacked via a stacking attachment. The present invention is characterized in that a pedestal in which stacking protrusions that engage with stacking grooves at the lower end of each cross frame are formed at four corners is disposed at the bottom of each cross frame. Further, the present invention is characterized in that a garbage bag mounting frame is detachably attached to a lower part of the stacking attachment, and these are used as means for solving the problems.

  With such a configuration, the present invention has a configuration in which a pair of intersecting frames each having a substantially central portion pivotally supported by a hinge shaft and configured to be foldable are connected and arranged at a predetermined interval and disposed at the upper end of each intersecting frame.

FIG. 2 is a bottom perspective view of a stacking attachment, showing a second embodiment of the folding sorting bin according to the present invention. FIG. 3 is a perspective view of a main part near the hinge axis of the cross frame. As shown in FIG. 1, the basic configuration of the present invention is that a pair of intersecting frames 1, 2, 3 and 4 having a substantially central portion pivotally supported by hinge shafts 5 and 6 and configured to be foldable have a predetermined interval. Are connected together (by connecting rods 7, 8, 9, 10) and are configured to lock the four corners of the opening of the garbage bag 22 to the upper ends of the cross frames 1, 2, 3 and 4 respectively. In the foldable sorting waste bin, a box-like stacking attachment 17 having a dust inlet 19 opened on the side surface is placed on the upper end of each of the crossing frames 1, 2, 3 and 4.

  FIG. 1 is an overall perspective view showing a first embodiment of the folding-type sorting waste bin according to the present invention. Each of the cross frames 1, 2, 3 and 4 constituting the frame of the waste bin functioning as a holder for the waste bag 22 is shown in FIG. The substantially central portion is pivotally supported by the hinge shafts 5 and 6 and is arranged so as to intersect in an X shape so that it can be folded. These intersecting frames 1, 2 and 3, 4 are arranged at a predetermined interval. The predetermined interval is defined by the upper connecting rods 7 and 8 and the lower connecting rods 9 and 10 which are provided between the vicinity of the upper and lower ends of the cross frames 1, 2 and 3 and 4. The crossing angle of the cross frames 1, 2 and 3, 4 is defined by the folding frames 11, 12 disposed between the lower ends of the cross frames 1, 2 and between the lower ends of the cross frames 3, 4. Each of the folding frames 11 and 12 includes a pair of first and second folding frames 11A, 11B and 12A, 12B that can be bent around the folding shafts 13 and 14 at substantially the center. The ends of these folding frames 11A, 11B and 12A, 12B are fitted and locked to both ends of the lower connecting rods 9, 10, but are fitted and locked to both ends of the upper connecting rods 7, 8. Also good.

  The vicinity of the upper and lower end portions of each of the cross frames 1, 2, 3 and 4 is formed to be bent somewhat so as to be directed substantially in the vertical direction when in a use state expanded at a predetermined cross angle. Accordingly, the upper and lower end surfaces of the intersecting frames 1, 2 and 3, 4 are formed substantially horizontally. Stacking projections 15 constituting locking portions are respectively formed at the upper ends of the cross frames 1, 2, 3 and 4 and the locking portions are formed at the lower ends of the cross frames 1, 2, 3 and 4. A stacking groove 16 (only reference numeral 16 is shown in FIG. 1) is formed. A plastic bag, a flexible container pack, or the like is accommodated in a space defined by each of these crossing frames 1, 2, 3 and 4, and the four corners of the upper opening thereof are locked to the stacking protrusions 15. . Reference numeral 29 denotes a display board indicating the type of garbage suspended from the upper connecting rod 7.

  In the present invention, a box-like stacking attachment 17 having a dust inlet 19 opened on the side surface is placed at the upper end of each of the cross frames 1, 2, 3 and 4. The stacking attachment 17 has a box-like body that is open at the bottom, and is provided with a dust inlet 19 on the side surface. In FIG. 1, the dust inlet 19 is arranged on the right side, but the same as the display board 29, avoiding the connecting portion 21 provided for integrating the cross frames 1, 2, 3, and 4. It can also be arranged on the side. If the arrangement of the upper end portions of each cross frame 1, 2 and 3, 4 is square, the stacking attachment 17 is also square, and the orientation of the stacking attachment 17 is arbitrary. About arrangement | positioning of the upper end part of each cross frame 1, 2, and 3, 4, a rectangle etc. can be selected suitably. A suspension door that can be swung back and forth is suspended from the garbage inlet 19 by a hinge 30 or the like, so that the odor of the waste can be cut off, and the suspension door can be pushed into the garbage easily.

  In the stacking attachment 17, only the stacking groove 16 (reference numeral 16 in FIG. 1 is shown) at the bottom portion that is aligned with the stacking protrusion 15 at the upper end of each of the intersecting frames 1, 2, 3, 4. 2) is formed. The engagement between the stacking projections 15 and the stacking grooves 16 ensures that the crossing frames 1, 2, 3 and 4 and the stacking attachment 17 can be engaged with each other, and at the same time, dust is collected in these engaging portions. If the four corners in the vicinity of the opening of the bag 22 are sandwiched, it is not necessary to separately form a special garbage bag locking portion in the cross frames 1, 2, 3, 4, and the like. Stacking projections 15 are formed at the four corners of the top plate. By locking the stacking groove 16 at the lower end of each cross frame to the stacking projection 15 of the stacking attachment 17, a plurality of trash can can be stacked via the stacking attachment 17. Multi-stage loading of a trash box composed of intersecting frames via the attachment 17 is possible stably.
