Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a waste reduction container for manually compressing and reducing the volume of combustible waste mainly composed of paper waste.

[0002]

2. Description of the Related Art Most combustible waste generated in offices is
Garbage mainly composed of shredded or rolled paper, cardboard such as paper boxes and paper cups, and paper scraps such as plastics made of sheets, bags, or small molded products (hereinafter referred to as paper waste) However, this paper waste has various shapes,
It is characterized by a very large specific volume.

[0003] In recent years, in the metropolitan area, the fee for collection of business waste has been promoted, and the collection cost is determined by the volume and number of garbage bags. Therefore, in business establishments that generate a large amount of paper waste, it is urgently necessary to reduce the volume. Has become an issue. In addition, it is desired for a waste collection company to reduce the volume of paper waste in order to streamline the collection operation.

Conventionally, many devices have been proposed for compressing and reducing empty cans, plastic bottles, paper cups, paper towels, paper waste, garbage and the like by using mechanical force. These are various types, such as those that press the compression plate using a cylinder such as a motor or hydraulic pressure, those that compress with air pressure with an air bag, and those that compress with a screw, but all of which are controlled in addition to the drive source. A mechanism and an operation panel are required, and the device structure becomes complicated.

[0005] In the case of refuse that can be reduced in volume by a relatively small compressive force, a number of refuse volume reducing means for compressing the refuse with human power without using mechanical force have been proposed. For example, a method in which a compression lever is pressed by a manual lever using the principle of leverage (JP-A-7-323)
No. 397), a compression plate operated by a foot pedal (Registered Utility Model No. 3022246, etc.), a compression plate lowered by its own weight or weight, and after compression it is rolled up (Japanese Utility Model No. 7-35405, etc.) Various types of manual dust volume reduction means have been proposed, such as a method in which an upright push rod is attached to the upper part of a compression plate and pressed by human power (Registered Utility Model No. 3040810).

[0006]

SUMMARY OF THE INVENTION As already mentioned,
The garbage reduction device using mechanical force has a complicated structure, is expensive, and requires a large maintenance burden. Therefore, as a container for reducing paper waste used individually in a small office, it is desirable that the waste can be compressed manually.

However, the required compressive force varies greatly depending on the type and shape of the refuse, and even paper waste often requires a considerable compressive force. It is desirable that the compression plate can be pressed smoothly and surely without using the compression plate.

Further, since the compression stroke varies greatly depending on the amount of dust in the dust container, it is desirable that the stroke can be varied with a large variable range and can be pressed with a substantially constant force in the entire range. Further, it is desirable that the structure and operation are relatively simple and that the interior furniture have a good appearance.

Conventional manual waste volume reduction means, for example, those which press the compression plate with a manual lever or a foot pedal,
There is a problem that it is difficult to increase the compression stroke. In addition, when the compression plate is pressed by its own weight or weight, the compression force cannot be adjusted, and there is a problem that if the own weight is increased, it becomes difficult to wind up. Furthermore, the structure and operation of the conventional manual waste volume reduction means are not always simple,
Few things have aesthetic problems as furniture.

Therefore, the present invention relates to a manual reducing container for combustible waste mainly composed of paper waste, which can press the compression plate smoothly and reliably, has a large compression stroke and a substantially constant entire stroke. It is an object of the present invention to provide a refuse reduction container that can press a force, has a relatively simple structure and operation, and has a good appearance as a fixture.

[0011]

SUMMARY OF THE INVENTION The gist of the present invention for solving the above-mentioned problems is to provide a container for reducing combustible waste mainly composed of paper waste, which has a waste container and a door on at least one side. A casing capable of accommodating the refuse container in a freely accessible manner, a refuse inlet and a pressing surface formed at an upper portion thereof, a split openable compression plate disposed at a lower end thereof, and provided on an upper surface of the casing; A guide mechanism configured to include a compression cylinder capable of moving up and down in the opening, a cross section of the compression cylinder being substantially similar to a cross section of the refuse container, having a slightly smaller shape, and preventing a lateral run-out of the compression cylinder; A positioning mechanism is arranged so that the compression cylinder can be moved up and down while maintaining a predetermined narrow interval between the outer wall and the inner wall of the garbage container, and a constant load spring body is fixed to the upper part of the casing, The lower part of the compression cylinder The distal end of the coil spring of the load spring is fixed, the compression cylinder is suspended and held at the top of the casing by the restoring force of the coil spring when not pressed, and the compression plate is manually opened and closed. A refuse reduction container characterized by including a remotely operated link mechanism.

Further, in the above-mentioned refuse reduction container, the restoring force of the coil spring of the constant load spring is 1.05 to 1.3 times the own weight of the compression cylinder.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 is a perspective view showing the entire structure of a waste reduction container according to a first embodiment of the present invention. This waste reduction container includes a waste container 1, a casing 2 for accommodating the waste container 1 so as to be able to enter and exit, and a compression cylinder 3 capable of moving up and down inside the waste container 1.
It is composed of

FIG. 2 is a perspective view showing the structure of the casing in this embodiment. The casing 2 has a door 4 on at least one side surface, the other side surface and the bottom surface are covered with a thin plate (in this embodiment, a thin steel plate), and the upper surface is open.

In the vicinity of the center of both sides adjacent to the mounting surface of the door 4 (hereinafter referred to as the front surface), two upright partition plates 5 are mounted at predetermined intervals over substantially the entire height of the casing 2. ing. The outer surface of the partition plate 5
As will be described later, it has a function as a guide plate of a guide roller 20 arranged in the compression cylinder 3.

Further, two constant load springs 6 are arranged on a shaft fixed inside the upper portion of the partition plate 5. The constant load spring 6 is defined in JISB0103, and a band-shaped coil spring is used in this embodiment. In addition, an upright protection plate 7 is stretched between the partition plates 5 (inside side surfaces). The protection plate 7 has a function of preventing intrusion of dust and increasing the strength of the casing 2, but it is not always necessary to provide this.

The upper portion of the protection plate 7 is cut out in a predetermined range,
The band-shaped spring 8 of the constant load spring 6 is configured to be able to be pulled out inward (center side of the casing) from the notch, and the tip of the band-shaped spring 8 is connected to a spring stopper 10 fixed to the lower part of the compression cylinder 3. Screwed.

A turn 9 having a predetermined width is provided all around the upper end of the casing 2. The fold 9 has a function of preventing dust from entering and exiting from between the casing 2 and the compression cylinder 3, but need not necessarily be provided. Alternatively, the fold may be made of a flexible material such as rubber. The folded portion 9 is provided with two notches 11 opposed to each other. As will be described later, a rod 18 for opening and closing the compression plate 13 of the compression cylinder 3 is provided in the notch 1.
Move up and down in 1.

Further, positioning guides 12 for the trash container 1 are attached to the bottom of the casing 2 in three directions except the front.

Further, although not shown in FIG. 2, an upright sliding plate is attached to the inner wall surface of the casing 2. FIG. 3 is a conceptual diagram showing an arrangement of sliding plates in a cross section of the casing. Sliding plate 21
Are mounted upright on the base almost over the entire height of the casing 2 near the inner end of the three walls except for the mounting surface (front) of the door 4 (shaded portion in the figure). Slides with the outer wall surface of the In the present embodiment, the sliding plate 21 is made of polyacetal resin (Delrin), but is not limited to this, and various low friction resin materials can be used.

FIG. 4 is a perspective view showing the structure of the compression cylinder in this embodiment. The compression cylinder 3 has four sides and an upper surface covered with a thin plate (a thin steel plate in this embodiment), and a split compression plate 13 is attached to the bottom surface. The outer end of the compression plate 13 is supported by two hinges 14, and is openable and closable. The cross section of the compression cylinder 3 is substantially similar to the cross section of the inner wall of the refuse container 1, and is formed such that its outer surface is slightly smaller than the inner surface of the refuse container.

At the upper front part of the compression cylinder 3, a dust inlet 15 is provided.
Are provided, and the upper surface 16 of the compression cylinder 3 can be used as a pressing surface when the compression cylinder is lowered by manual power. The refuse inlet 15 is supported by a shaft (not shown) so as to be openable and closable, and is configured to be held at a predetermined position in both an open state and a closed state by a one-touch lock (not shown). I have.

The compression plate 13 and the refuse inlet 15 are connected by a link mechanism, and both are linked. That is, the lever 17 on the side of the compression plate 13 is connected to the lever 19 on the side of the refuse inlet 15 through a pair of rods 18. As a result, when the refuse inlet 15 is opened, the compression plate 13 is also in the open state (the position indicated by the broken line), and when the refuse inlet 15 is closed, the rod 18 descends and the compression plate 13 is closed. Are also configured to be in a closed state.

At the lower part of the side surface (both sides adjacent to the front surface) of the compression cylinder 13, two pairs of upper and lower guide rollers 20 are mounted, respectively.
It is set to be equal to the interval between the outer surfaces of the partition plate 5 of the casing 2. The reason why the guide rollers 20 are provided in the upper and lower two stages is to move the compression cylinder 3 up and down more smoothly, but this may be one stage (one pair).

A spring stopper 10 is fixed to the outer wall surface of the compression cylinder 3 below the inside of the guide roller 20, and the tip of the band-shaped spring 8 of the constant load spring 6 is screwed to the stopper 10.

The waste reducing container of the present embodiment has the above-described configuration. The operation of the waste reducing container will be described below. First, when storing the garbage container 1 in the caging 2, usually, a garbage bag of a plastic sheet in the garbage container 1 is laid and stored (the upper part of the garbage bag is folded back to the outside of the container).

At the time of non-compression, the compression cylinder 3 stands on the upper part of the casing 2 by the restoring force of the constant load spring 6. At this time, the guide roller 20 is supported by the partition plate 5 and the lower portion of the outer wall surface of the guide tube 3 is supported by the upper portion of the slide plate 21 to prevent the guide tube 3 from falling. When the guide cylinder is standing (non-compressed), the dust inlet 15 is manually opened, whereby the compression plate 13 is also kept open.
Therefore, the inputted paper waste falls into the waste container 1.

Next, at the time of compression, the dust inlet 15 is first closed. As a result, the compression plate 13 is also closed, and a flat compression surface is formed on the lower surface of the compression cylinder 3. In this state, the upper surface 16 of the compression cylinder is pressed downward by human power.
The compression cylinder 3 is smoothly lowered by the guide mechanism including the guide roller 20 and the partition plate 5 and the guide mechanism including the slide plate 21 and the outer wall surface of the compression cylinder.

When the compression cylinder 3 is lowered, the band-shaped spring 8 of the constant load spring 6 is pulled out. Since the constant load spring has a substantially constant restoring force over a long stroke,
Regardless of the descending stroke, it is possible to descend with a substantially constant pressing force. If the restoring force of the constant load spring 6 is set to be slightly larger than the own weight of the compression cylinder 3, the compression cylinder 3 can be lowered with a very small force.

The cross-sectional shape of the compression cylinder 3 is substantially similar to that of the refuse container 1, and is slightly smaller than this. The compression cylinder 3 is positioned by the guide mechanism, and the trash container 1 is positioned by the positioning guide 12. Thereby, a predetermined interval, for example, a narrow interval of about 3 to 10 mm is maintained between the outer wall surface of the compression cylinder 3 and the inner wall surface of the trash container 1. Therefore, not only the compression cylinder 3 descends smoothly, but also paper dust is not caught between the two wall surfaces. Therefore, paper waste can be efficiently compressed without using unnecessary force. Also, the present invention is characterized in that the pressing surface is made sufficiently large so that the user can press the body by applying weight as necessary.

When the user releases his hand after the end of compression, the compression cylinder 3 rises by the restoring force of the constant load spring 6 and returns to the original standing position. In this state, the refuse inlet 15 is manually opened to continue using the refuse container. It is sufficient to open the door 4 and pull out the garbage container 1 to take out the garbage bag in a state where the garbage container 1 is filled with the compressed paper waste by repeating the charging and compressing of the garbage.

In the present invention, the restoring force of the coil spring of the constant load spring 6 is 1.05 of the weight of the compression cylinder 3.
It is desirably about 1.3 times. Restoring force is 1 of its own weight.
If it is less than 05 times, the compression cylinder 3 may not rise smoothly. If it exceeds 1.3 times, an unnecessary force is required to press the compression cylinder 3.

FIG. 5 is a perspective view showing the entire structure of a waste reduction container according to a second embodiment of the present invention, and FIGS. 6 and 7 are perspective views showing the structure of a compression cylinder and a casing in this embodiment. is there. Also in the second embodiment, the waste reduction container is composed of the waste container 1, the casing 2, and the compression cylinder 3, and is characterized in that a cover is provided outside the compression cylinder 3.

That is, as shown in FIG. 6, the side surface of the compression cylinder 3 has a double structure of the inner cylinder 22 and the cover 23. Similar to the compression cylinder of the first embodiment, the cross-sectional shape of the inner cylinder 22 is substantially similar to and slightly smaller than the refuse container 1, and the cross-sectional shape of the cover 23 is substantially similar to the casing 2, It is formed slightly larger than here.

Also in the second embodiment, a dust inlet 15 is provided in the upper front part of the compression cylinder 3 and the upper surface 16 of the compression cylinder 13 is provided.
Can be used as a pressing surface as in the first embodiment. Further, the compression plate 13 which can be freely opened and closed outward is attached to the lower surface of the compression cylinder 3 by a hinge 14, and the compression plate 13 is further opened and closed by a link mechanism connected to the refuse inlet 15. This is the same as in the first embodiment.

The difference is in the position where the guide roller 20 is mounted and the position where the spring stopper 10 is mounted. That is, in the second embodiment, the inner cylinders 2 on the front and back of the compression cylinder 3
The lower end of the roller 2 is slightly narrowed, and one guide roller 20 is attached near each of both side ends of the narrowed portion. The guide roller 20 has a function of using the inner surface of the refuse container 1 as a guide plate to prevent the compression cylinder 3 from swaying and to correct the position of the refuse container 1 so that the compression cylinder 3 can be smoothly lowered. Having. In this embodiment, the spring stopper 10 is attached to the lower end of the inner surface of the cover 23 instead of the outer surface of the inner cylinder 22.

Further, the structure of the casing 2 is slightly different from that of the first embodiment. As shown in FIG. 7, a vertical groove 24 having a predetermined width is formed near the center of both side surfaces adjacent to the front surface of the casing 2 over the entire height of the casing.
Two constant load springs 6 are attached to the upper portions of the vertical grooves 24, but the difference from the first embodiment is that the band-shaped springs 8 are drawn out.

However, the tip of the band spring 8 is
The compression cylinder 3 is fixed to the upper part of the casing 2 by being screwed to a spring stopper 10 fixed to the lower end of the inner surface of the cover 23 of the compression cylinder 3, and by the restoring force of the coil spring of the constant load spring 6. Is common to both embodiments.

In this embodiment, the sliding plate 21
Is mounted on the inner surface of the cover 23 (not shown in FIG. 6), and the arrangement of the cover 23 in the cross section is the same as that of FIG. Acts as a guide mechanism for keeping the interval of the constant. Further, the positioning guide 12 of the refuse container is attached to the bottom of the casing 2 as in the first embodiment.

The features of the waste reducing container of the second embodiment are that its appearance is good and that there is little problem with maintenance. That is, when used regularly in an office, the appearance as indoor furniture is also important, but since the cover is provided on the outer periphery of the compression cylinder, there is an advantage that it is hard to recognize as a waste reduction container. In the configuration of the first embodiment,
There is a concern that dust may be trapped between the compression cylinder and the casing during long-term use, and that dirt and deformation may occur around the folded portion 9 at the upper part of the casing. However, in the dust reducing container of the second embodiment,
It has the advantage that there is no such concern.

Although the structure of the first embodiment and the structure of the second embodiment have the above-described differences, their operations are very similar, so that the detailed description of the latter operation will be omitted.

The main functional features of the waste reduction container of the present invention are as follows. The distance between the inner wall of the trash container and the side of the compression cylinder is reduced to prevent dust from being trapped between them.A guide mechanism to prevent the compression cylinder from swaying and a positioning mechanism for the trash container to provide compression. The cylinder can be moved up and down smoothly and securely so that unnecessary force is not required for compressing the dust.The upper part of the casing and the lower part of the compression cylinder are connected by a constant load spring, and the compression cylinder is fixed at the upper part of the casing. At the same time, regardless of the downward stroke of the compression cylinder, it should be able to press the dust with a substantially constant force. Appropriate shape is selected Opening and closing of the compression plate can be manually and easily and reliably remotely controlled

Therefore, the waste reducing container of the present invention is only required to be capable of exhibiting the above-mentioned various functions, and the configuration is not limited to the above-described first or second embodiment.

With respect to the compression cylinder and the refuse container, the cross-sectional shape is substantially similar, and the outer dimensions of the former are slightly smaller than the inner dimensions of the latter. It may be elliptical or the like. The cross-sectional area does not need to be limited.

Regarding the guide mechanism, any guide mechanism may be used as long as it can be moved up and down while maintaining a constant gap between the wall surface of the compression cylinder and the waste container or / and the casing wall. Any of a combination with a wall surface or a guide plate may be used, and these may be arranged alone or provided together. The number and the mounting position may be appropriately selected. In addition, the positioning mechanism for the trash container does not necessarily need to be provided on the bottom surface of the casing, but may be provided on the side surface thereof, and a guide roller may be used if necessary.

Regarding the constant load springs, it is desirable to arrange one each of the constant load springs on at least the opposing surfaces, but the number and the mounting position may be selected as appropriate.

Regarding the pressing surface and the dust inlet, the shapes and positions may be, for example, as shown in FIG. 8 (a) or (b). In this case, the opening and closing of the compression plate may not be linked to the opening and closing of the inlet, but may be opened and closed by a separately provided link mechanism.

As for the compression plate, it is preferable that the opening and closing of the compression plate can be manually controlled remotely. As in the present embodiment, the opening and closing of the refuse inlet and the compression plate may be interlocked. The compression plate may be opened and closed by a lever. Alternatively, as shown in FIG. 9, the opening and closing of the split compression plate 13 is linked by a pair of bevel gears 26 arranged at both ends of a shaft 25, and this shaft 25 is May be rotated by a knob 28 attached to the upper part of the head.

[0049]

According to the dust reducing container of the present invention, dust is not caught between the wall of the dust container and the compression cylinder, so that the dust can be compressed smoothly without using unnecessary force. . Further, since a constant load spring is used, compression can be performed with a constant force regardless of the amount of dust. Furthermore, since the pressing surface is large, it is possible to compress the dust by applying weight as needed.

The dust reducing container of the present invention has a relatively simple structure and high durability. Since the compression cylinder is raised by a constant load spring, the dust compression operation is relatively simple.
