DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a relatively large garbage bin for temporarily storing garbage, particularly a relatively heavy and large amount of commercial garbage from stores and the like.

[0002]

2. Description of the Related Art In general, large trash cans for business use are usually prepared by first loading a storage bag in a trash can, filling the storage bag with garbage at any time, and then filling the storage bag. The storage bag is taken out of the recycle bin and transported appropriately.

[0003] Therefore, according to this kind of large-sized industrial trash can, since the garbage collection process is performed collectively and watertightly and hermetically instead of as described above, it is relatively simple and easy. Environmental health can be achieved.

[0004]

However, the above-mentioned conventional large-sized trash can still has a major drawback to be improved as described below.

That is, this type of trash can has a high shape because of the large amount of garbage to be stored, and the storage bag filled with garbage loaded into the trash can also Is relatively heavy, which makes it quite heavy.

For this reason, in the conventional trash box, considerable effort and inconvenience have been required to remove the heavy filled storage bag from the high trash box during garbage collection processing.

[0007] Therefore, an object of the present invention is to provide a business that can relatively easily take out a heavy storage bag filled with a large amount of relatively heavy garbage from a high garbage bin formed at a required height. To provide a large recycle bin for

[0008]

In order to achieve the above-mentioned object, a multi-stage telescopic trash can according to the present invention comprises an inverted trapezoidal multi-stage divided case sequentially inserted and connected in a nested manner. Wherein the lowermost divided case has a bottom surface formed with a flange, and the lowermost and intermediate divided cases are fixed to hold the respective upper divided cases in the extended position when each divided case is extended. It is characterized by having means.

In this case, it is preferable that the size of the upper surface of the lower case is set smaller than the size of the bottom surface of the upper case.

The locking means comprises at least two projections formed on the outer peripheral surface of the upper part of the lower case, an inward flange formed on the bottom opening edge of the upper case, and a lower part of the lower case. It comprises an outward flange formed at the upper opening edge and at least two or more projections formed below the outward flange by a predetermined distance.

As another form of the locking means, an inward flange portion is formed at the bottom opening edge of the upper divided case, while an outward flange portion is formed at the upper opening edge of the lower divided case, and these inward flange portions are formed. The upper case and the lower case are firmly fixed by engaging the outer flange portion with the outer flange portion, so that the so-called case can be prevented from coming off.

Further, by forming the inward flange portion and the projection formed on the outer surface of the lower case in a round shape, the inward flange portion can smoothly ride over the projection simply by lightly pushing down the upper case, and thus the long-term operation can be achieved. Wear of the projections due to use can be prevented.

It is preferable that the uppermost divided case is provided with a pulling handle on the upper outer peripheral wall surface, and is provided with a separate lid for covering the upper surface.

Further, each divided case is formed of an inverted conical or polygonal trapezoidal elastically deformable plastic product.

As described above, the multi-stage telescopic trash can of the present invention is configured so that its height can be expanded and contracted as required. Thus, according to the present invention, it is clear that even a heavy garbage storage bag can be relatively easily removed from the trash can by reducing the height of the trash can. Also,
The recycle bin of the present invention has the advantage that it is relatively simple to construct and can be easily extended and retracted.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is an exploded perspective view of a multi-stage telescopic bin according to the present invention.

First, the embodiment described below relates to a two-stage telescopic type. However, since the principle of the present invention is clearly disclosed thereby, examples having three or more stages will be described. Is omitted.

1 to 5 relate to a two-stage telescopic trash can according to the present invention. Briefly, FIG. 1 is a perspective view of an embodiment having an inverted square trapezoidal divided case, and FIG. FIG. 3 is a perspective view of an embodiment having an inverted truncated conical split case, FIG. 3 is a sectional view taken along the line III-III of FIG. 2, FIG. 4 is a state in which the upper and lower portions are engaged and fixed, and FIG. It shows a state where the case is pushed down to the lower divided case.

Therefore, the trash can according to the present invention basically comprises inverted plastic trapezoidal upper and lower divided cases 10 and 12 which are inserted and connected in a nested manner. Bottom 16 with 14
And four locking means 18 for holding the upper divided case 10 in the extended position when the divided cases 10 and 12 are extended.

The diameter of the upper opening of the lower divided case 12 is set smaller than the size of the lower edge 20 of the upper divided case 10. Therefore, the split cases 10, 1
When the length 2 is shortened, the lower divided case 12 is inserted into the upper divided case 10, as best shown in FIG.

A round head projection 18 is provided on the upper outer peripheral wall surface of the lower divided case 12, whereby the lower divided case 12 is elastically pressed against the upper divided case 10.

The upper division case 10 is provided with a pulling handle 22 on the upper outer peripheral wall surface.
On the upper surface, a separate lid 32 for covering the upper surface is used.

Next, in FIG. 4, an inward flange portion 24 is formed at the opening edge of the lower end of the upper split case 10, and an outward flange portion 26 is formed at the upper end opening edge of the lower split case 12, so that both flange portions are formed. The upper case can be prevented from coming off from the lower case having a large waste weight when the trash can is moved by being firmly engaged. Further, by forming the round portion 28 on the inward flange portion 24, it is possible to smoothly pass over the round head projection 18 only by pushing down the upper divided case 10 lightly.

Therefore, in the trash can of the present invention having such a structure, referring to FIGS. 3 and 5, for example, at the extended position L1 in the figure, the upper end surface of the upper divided case 10 is pressed with an appropriate force F. Then, the upper-stage split case 10 is configured such that the lower end opening end 20 of the lower-stage split case 12
The free section where the head 18 is separated from the inner surface of the upper split case 10 after being pushed down on the sliding section M1 in which the head 18 is pressed against the inner surface of the upper split case 10 by climbing over. M2 is dropped freely. That is, it is easily compressed to the shortened position L2.

On the other hand, when the upper divided case 10 is pulled up from the lower divided case 12 via the handle 22 at the shortened position L2, the upper divided case 10 is first freely pulled up in the free section M2 and then slid. After the moving section M <b> 1 is pressed and pulled up, the lower end opening edge 20 passes over the conical projection 18, so that it is elastically locked and held at the extended position L <b> 1 on the lower division case 12. It is to be noted that an appropriate lifting force is required when the upper divisional case 10 is pressed and raised in the sliding section M1 and passes over the round head projection 18, but during this operation, the flange 14 of the lower divisional case 12 is stepped on. Since the lower case 12 can be attached and pressed, the lower case 12 is not pulled up together with the upper case 10, and the operation can be performed relatively easily. In addition, the holding of the upper divided case 10 at the extended position L1 is not only a pressing engagement force of the round head projection 18 but also an adhesion force between the two divided cases 10 and 12 in the adhesion section M3. Can be achieved.

However, after prolonged use, the protuberance 1
8 may be worn away, its elasticity may be degraded, and as a special circumstance, an oily substance may adhere to it and its sticking force may be reduced.

Therefore, by adopting the structure of the embodiment shown in FIG. 4, the inward flange portion 24 provided at the lower opening edge of the upper divided case 10 is provided with the outward flange portion 26 provided at the upper opening edge of the lower divided case 12. And a round head projection 18 protruding near the lower part thereof, and is stably fixed against vertical movement.

As described above, the garbage box of the present invention is constructed so that its height can be expanded and contracted. Therefore, according to the present invention, when the garbage is filled in the storage bag 30, the extended position L1 is set.
When the full storage bag 30 is to be taken out, the waste storage bag 30 having a large weight can be relatively easily taken out of the trash box by setting it to the shortened position L2 when taking out the full storage bag 30.

Although the present invention has been described with reference to a preferred embodiment, the present invention is not limited to the above-described embodiment.
Many modifications can be made without departing from the spirit thereof. For example, in the described embodiment, the recycle bin is 2
Although it is configured in a staged manner, a three-staged structure may be employed with a similar structure.

[0030]

As described above, the multi-stage telescopic trash can according to the present invention is composed of an inverted trapezoidal multi-stage divided case which is inserted and connected in a nested manner, and the lowermost tier is divided. The case has a bottom surface on which a flange is formed, and the lowermost and middle divided cases are configured to include locking means for setting and holding the upper divided cases at the extended position when each divided case is extended. Things
In other words, in summary, since the height of the trash can is configured to be able to expand and contract relatively easily as necessary, even a heavy storage bag filled with a relatively large amount of relatively heavy garbage in the trash can is compared with the trash can. It becomes possible to take out easily.

The trash can of the present invention has the advantages of being relatively simple in construction, easily expanding and contracting, being compactly stacked, and being freely disassembled.
