[Technical field to which the device belongs]

  The present invention relates to a protective frame for a garbage collection site. More specifically, the present invention is Installed in a garbage collection place such as a street or apartment, the garbage mainly discharged from homes Enclose the boxes in a box shape and fold them up when the collection of garbage is finished. The present invention relates to a protective frame for a place where garbage can be collected.

[0002]

[Prior art]

  Garbage mainly produced from households is generally made of plastic film. , For example, a predetermined garbage collection packed in a polyethylene bag (polybag) It is designed to be placed in a loading place. Usually, household waste is treated as follows. Has been done in. A so-called poly bucket with a lid is lined with a plastic bag to store dust. Put it in a room and store garbage and burning garbage in it. The day to take out the trash Then, close the mouth of the plastic bag, take it out of the plastic bucket, and remove it from the designated garbage collection site. Go out to the place. Before the day to put out the trash, the plastic bag for the trash was full In that case, close the mouth of the plastic bag, take it out of the plastic bucket, and Put it in the liner and store the plastic bag full of dust in another place. Put. Of course, these will be put together with the garbage on the same day. Such trash Plastic film bags, so-called plastic bags, are usually used in local governments such as cities and towns. It is designated by a co-organization.

[0003]   Since the plastic bag containing garbage contains garbage and various organic waste, The mouth is closed properly and care is taken to prevent leftovers from leaking. Like that Garbage collection places for placing such plastic bags are commonly found, for example, on the edge of a road or in a corner of an apartment. It is set in a designated place that does not interfere with traffic or walking.

[0004]   If there is a garbage collection site in the corner of the road, a standing bill such as a "garbage collection site" There is a stand, and I try to place a plastic bag with garbage in the place. It Then, after placing a plastic bag containing garbage, cover it with a net etc., I try not to be ruined by a crow or a stray cat.

[0005]   If you have a garbage collection site in a corner of a residential area, ing. For example, there is a special place surrounded by a short concrete fence, I put or put a plastic bag containing garbage in the place. Or made of aluminum There is a basket made of a net fence of, and there are plastic bags containing garbage. It is piled up. Rather than having a basket inside, a specific place was made of aluminum net. In some cases, the expression of covering with a tofence is appropriate.

[0006]   In addition, I made a box from an iron plate and installed it in a predetermined position, and there was dust in the box. There are also cases where plastic bags are accumulated.

[0007]   However, the above-mentioned waste collection place has the following problems. (1) Crows and stray cats are causing the damage of raw garbage. road If you place a garbage bag in the corner of the road and put a plastic bag containing The net is covered, but this net is not very effective. In other words, the internet is free Because it will move, crows and stray cats scrub the leftovers of raw garbage and the garbage collection place is raw It is scattered with dust. Even if the net is covered, the net of the net is rough It is possible to easily catch raw garbage by using the Will be scattered.

[0008] (2) A safety problem that a plastic bag containing trash sticks out on the road and narrows the sidewalk There is. Set up a garbage collection place in the corner of the road and put a plastic bag containing garbage in the net The way to cover is that people who put out plastic bags containing garbage later will accumulate in the back Since it is awkward, it will be pulled out to the front, and the plastic bag gradually protrudes to the road side Becomes As a result, the sidewalk for pedestrians becomes narrower, and pedestrians should walk on the side of the roadway. Next to it is dangerous. People traveling by bicycle are also at increased risk.

[0009] (3) Boxes and baskets for collecting plastic bags containing garbage, and plastic bags containing garbage at the collection site Since the net for covering the bag is difficult to clean and wash, it is often left unused. Unhygienic. Usually, the collection place after collecting garbage is dried with a broom. Although it is easy to sweep and collect the water, it is not necessary to wash it with water using a hose. It's weird. Therefore, if leftover food or soup is spilled, it will remain as it is, and fly etc. Very unsanitary. If the above boxes and baskets can be easily moved, they can be washed with water. However, since these boxes and baskets are usually heavy items and mainly stationary, they are It's difficult to move.

[0010] (4) There is dust inside a box surrounded by an iron box or a short concrete fence. Placing the bag also has the problem that it is difficult to manage because it cannot be seen from the outside. In other words, even if non-burnable or oversized waste is illegally dumped at the waste collection site, Not sure, it can be said that there is a management problem.

[0011]
