Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a dust bag holder to which a dust bag is attached, a dust bag roll holder for a dust bag holder that holds a dust bag roll so that it can roll and cannot fall off,
Also, the present invention relates to a dust box in which a garbage bag holder is stored.

[0002]

2. Description of the Related Art A large number of garbage containers (garbage bins) are placed in places where a large number of people come and go, such as downtown areas, tourist spots, parks, train stations, movie theaters, and theaters. As a garbage container,
A cylindrical body made of plastic or a rectangular body is widely used, and in this type of waste container, a waste bag is attached by folding the opening end around the edge of the upper opening,
It is designed to put garbage in this garbage bag. That is,
The garbage container itself is used as a garbage bag holder.

As described above, if the dust is put in the dust bag attached to the dust container, the dust can be collected by exchanging the dust bag, and the dust can be collected easily. In addition, water, small dust, etc. do not leak or scatter from the dust container, and contamination around the dust container is prevented.

However, while the garbage container as a garbage bag holder is convenient, it is a problem from the viewpoint of scenery and aesthetics because the garbage container itself is exposed to the outside. Particularly, in the case of a cylindrical trash container made of a net, trash bags are also confirmed from the outside, and even trash inside the trash bags can be seen, greatly impairing the scenery and aesthetics.

Therefore, recently, there is a tendency that the dust container is put in a box called a dust box. The dust box is designed in consideration of its aesthetic aspect, and usually has a substantially rectangular parallelepiped having a slit-shaped or circular dust inlet on the top or front and a hinged openable door on the side.

[0006] In this way, if the dust container is put in the dust box and shielded from the outside, the dust container will not be visible. Moreover, since the dust box that can be seen from the outside has an aesthetic design, the appearance and the scenery are not impaired, and the existence of the dust box does not give a strange feeling.

[0007]

If the dust container is put in the dust box, the problems of aesthetics and scenery can certainly be solved. However, the work of collecting dust is complicated and the work efficiency is reduced, which causes fatigue of the worker.

When the dust container is put in the dust box,
Garbage is collected by the following procedure.

Open the dust box door. Pull the garbage container out of the dust box. Remove the garbage bag full of garbage from the garbage container and attach a new garbage bag to the garbage container (replace the garbage bag). Push the trash container with a new trash bag into the dust box. close the door.

Here, in the conventional case where the dust container is not put in the dust box, the dust can be collected only by exchanging the dust bag, that is, in one step.

In this way, collecting garbage, which was a single process,
Open and close the door (), remove the garbage container, push it in (
) Is added to the total of 5 steps, which makes the waste collection considerably complicated and reduces the work efficiency. In particular, the additional steps of opening and closing the door (), taking out the dust container, and pushing in () are all carried out in a moderate manner, so that the burden on the worker is heavy and the worker is easily tired.

Plastic containers are widely used as garbage containers. However, in a plastic trash container, dust adheres to the container and it becomes dark and must be cleaned regularly. Further, a plastic waste container left outside is liable to be broken due to the difference in temperature and temperature, and needs to be replaced in a short cycle.

Further, in both plastic and net dust containers, the open end is folded back to hang the dust bag on the dust container, but when dust is collected, a force for pulling down the dust bag is generated and the upper end of the dust bag May be removed from the garbage container.

When the dust is thrown into the trash bag whose upper end is removed from the trash container, the trash does not enter the trash bag and falls between the trash bag and the trash container. In the case of a net dust container, the surroundings are soiled, and it is necessary to clean the dust container or its surroundings. Therefore, in order to prevent the upper end of the dust bag from coming off from the dust container, it is widely practiced to hang the rubber band around the dust bag and firmly attach it.

Therefore, in the conventional garbage collection, in addition to the complicated replacement of the garbage bag, cleaning of the garbage container,
The additional work such as replacement of the dust container itself and hanging of a rubber band complicates dust collection, resulting in a decrease in work efficiency.

By the way, a garbage bag used for this kind of garbage container is, for example, a continuous bag which is continuously defined through perforations and is wound in a roll shape with folding of left and right ends. It has been known. According to this continuous type garbage bag, it is not necessary to facilitate the next new garbage bag every time the garbage bag is replaced, so that the replacement work can be simplified.

However, since the conventional dust container does not have a means for holding the dust bag roll, it must be left on the bottom surface. By leaving the dust bag roll on the bottom like this and using the dust bag, the rolling of the dust bag roll is unraveled more than necessary due to the trackless rolling accompanying the pulling up of the dust bag in which the dust is collected. The excessively pulled out garbage bag easily makes the next garbage bag exchange operation complicated.

The present invention simplifies the collection of dust and reduces the burden on workers, and the dust bag holder that can hold the dust bag roll in a state suitable for use, and the dust in the dust bag holder. An object of the present invention is to provide a dust bag roll holder suitable for use as a bag roll holding means, and a dust box in which the dust bag holder is stored.

[0019]

To achieve this object, a dust bag holder according to an embodiment of the present invention comprises an upper frame, a lower frame, a dust bag support frame, a rear frame, and dust that are frame members. Equipped with bag roll support frame and side frame, for example, using the back frame,
It is configured to be fixed and suspended on the inner surface of the dust box door.

The upper frame is formed so as to be elastically deformable by a part of the notch, and the dust bag pulled out from the dust bag roll on the dust bag roll support frame is folded back at the opening end outside the upper frame. It can be attached and held. The lower frame is connected to the upper frame through the vertical frames on the left and right of the front end, and the garbage bag support frame with a continuous shape of approximately S can support the bottom of the garbage bag, with its front end facing up and the front of the lower frame. Is extended and installed.

The rear end of the dust bag roll support frame is bent upward so as to engage with the placed dust bag roll. A rear frame is provided at the rear of the upper frame, and the dust bag holder is fixed and suspended on the inner surface of the door of the dust box via the rear frame.

[0022]

Embodiments of the present invention will be described below in detail with reference to the drawings.

FIG. 1 is a schematic perspective view of a dust box 10 on which a dust bag holder 12 is fixed and suspended, and FIGS. 2 and 3 (A) are a schematic perspective view and a right side view of the dust bag holder, respectively. As shown in FIG. 1, the dust box 10 is, for example, a substantially rectangular parallelepiped, and a dust inlet 14 is formed on the upper surface thereof.

In this embodiment, the dust input port 14
Has a slit shape (a long hole shape), but has a circular shape for cans. Further, the dust input port 14 is usually formed on the upper surface of the dust box 10, but it may be formed on the front surface and the left and right surfaces so that the dust can be input from the side.

As shown in FIG. 1, a door 16 with a hinge 18 is provided on the side surface of the dust box 10. When the hand is pulled on the concave portion 20 serving as a handle, the door 16 is opened as shown by the alternate long and short dash line, and the dust bag holder 12 is fixed and suspended on the inner surface of the door. Then, the dust bag 22 is attached to the dust bag holder 12. In this embodiment, the door 16 is provided on the front surface out of the four side surfaces of the front surface, the left and right surfaces, and the back surface.
It may be provided on the left and right surfaces or the back surface.

As can be seen from FIG. 2 in addition to FIG. 1, the garbage bag holder 12 includes an upper frame 24, a lower frame 26,
Support frame 28, rear frame 30, reinforcing frame 32, connecting rod 34,
For example, the rear frame is used to be fixed and suspended on the door 16 of the dust box.

The upper frame 24 is formed by bending a part of the upper frame 24, that is, a shape having a notch 24a, and the peripheral length (peripheral length) of the upper frame including the notch is the garbage bag 22. The upper frame is configured to be larger than the circumference. Notch 24
Since there is a, elasticity is generated in the upper frame 24. And a garbage bag
Hang it on the upper frame 24 while folding the open end of 22 outward.
The upper frame is elastically deformed to reduce its circumference,
The garbage bag can be easily attached to the upper frame.

After the dust bag 22 is attached, its attaching force,
In other words, the upper frame 24 returns to its original shape except for the pressing force in the contracting direction. Here, the circumference of the upper frame 24 in the original shape is larger than the circumference of the dust bag 22, and the folded portion of the open end of the dust bag is pushed out by its restoring force (elasticity), so that the dust bag is Firmly mounted and held on the frame.

As described above, since the upper frame 24 is provided with the notches 24a to generate elasticity, the dust bag 22 is easily and firmly attached to and retained on the upper frame. In other words, even if the accumulated dust causes a force to pull down the dust bag 22,
Since it is held in the mounted state under the restoring force of, the rubber band hook for preventing the dust bag from coming off is unnecessary.

As shown in FIG. 2, here, the upper frame
Although a substantially hexagonal shape is illustrated as the shape of 24, the shape is not limited to this, and other shapes such as an ellipse, a circle, and an octagon may be used.

The lower frame 26 has a substantially U shape and is formed by bending, and its left and right end portions 26a are extended upward so that it can be used as a vertical frame. And this vertical frame (end) 26a is the upper frame 24
The lower frame 26 is connected to the upper frame by being fixed to the side part of the.
Further, the lower frame is reinforced by erection and connection between the left and right vertical frames 26a by the connecting rod 34.

When the dust bag holder 12 is fixed and suspended on the inner surface of the dust box door 16, the dust bag holder is held apart from the bottom surface of the dust box by a predetermined distance, that is, suspended. Vertical frame 26a consisting of left and right edges
The height of the lower frame 26 including is formed lower than the height of the door of the dust box. That is, the dust bag holder 12 is held and suspended in a floating state when fixed to the door 16 of the dust box. The shape of the lower frame 26 is not limited to the substantially U shape,
Other shapes may be used.

Here, the left and right vertical frames 26a may be extended obliquely from the lower frame 26 in the expanding direction. Inclining the vertical frame 26a in the expanding direction as described above not only prevents the garbage bag 22 from excessively bulging to the side even when the garbage bag 22 is filled with dust, but also prevents the garbage bag 22 from extending along the vertical frame. Since it is possible to sufficiently pull up, the work of pulling up the dust bag can be carried out smoothly and easily.

A support frame 28 formed into a substantially S continuous shape is attached to the connecting rod 34. FIG.
As can be seen from (A), the support frame 28 is provided obliquely with its front end facing upward, and its rear end located below is bent upward. In this embodiment, the front half of the support frame 28 located in front of the connecting rod 34 is used as a support for supporting the bottom of the dust bag 22.

The continuous shape of approximately S is a generic term for a single rod that is repeatedly bent forward and backward, or a combination of a plurality of rods that are substantially S-shaped and bent. The shape does not matter. With the support frame 28 having such a shape, the dust bag 22 can be supported at many positions.

For example, in this embodiment, a single rod is bent five times as shown in FIG.
The book rods extend to intersect the connecting rods 34. Therefore, the dust bag 22 is supported by the six rods, and the support frame 28 has sufficient strength to withstand the weight of dust. It is preferable from the standpoint of strength and processing that the support frame 28 is formed by bending and forming a single rod rather than combining and forming a plurality of rods.

When the dust is collected in the dust bag 22, the dust bag is inflated. As can be seen from Fig. 2, the bulge in the rear direction is the rear frame.
At 30, left and right bulges are prevented by the left and right vertical frames 26a. However, since the front surface of the dust bag holder 12 is opened, the surface (rear surface) of the dust box 10 that opposes when it is inflated forward, and the reaction force thereof pushes back the door 16 and may open the door naturally. is there.

However, in this embodiment, the support frame 28
Is inclined with its front end facing upward, the weight of dust collected in the dust bag 22 acts rearward along the inclination, and bulging forward is prevented.

As described above, although the dust bag 22 is stored without using the net or plastic dust container, the bulge is prevented and the dust box door 16 is prevented.
Will not be released naturally.

The rear end of the support frame 28 located below the front end is bent upward, and the dust bag roll 36 is placed and held on the support frame by utilizing the bent end 28a. That is,
By tilting the support frame 28 and bending the rear end upward, the dust bag roll 36 can be held at a predetermined position by using the bent end 28a as a stopper.

Needless to say, the dust bag roll 36 is formed by heat-sealing and sealing a tubular material such as polyethylene for each predetermined length and providing perforations immediately after the sealing. A garbage bag 22 is obtained.

In particular, in this embodiment, as shown in FIG. 4, the dust bag roll 36 is formed by opening upward in the longitudinal direction and folding both sides thereof between the front and rear surfaces.
If you fold both sides between the front and back like this, a garbage bag
The front and rear surfaces 22f and 22r of 22 become narrower, and the front and rear surfaces themselves can be molded without being folded. That is, it is not necessary to open the front and rear surfaces 22f and 22r, and the next dust bag 22 can be obtained by simply pulling out the dust bag roll 36. Reference numeral 22s indicates a seal.

In this embodiment, a garbage bag roll
36 is a so-called "2" with both sides folded up to near the center
It is folded and molded in "1/2 width folding", but it can be folded in such a way that the action of spreading the front and rear surfaces 22f, 22r is not necessary, and it is not "1/2 width folding" but "3/3 width folding". It may be "1 width folding" or "1/4 width folding".

Since the dust bag roll 36 is placed on the support frame 28, the dust bag 22 in use is removed from the upper frame 24, pulled out and then cut off along the perforations 22m, and the next dust bag is placed on top. Simply unfold and attach to the upper frame, the garbage bag can be replaced, and the garbage bag can be replaced quickly. In particular, by using the dust bag roll 36 that is opened upward and has both sides folded between the front and rear surfaces, the dust bag can be replaced more quickly.

The rear frame 30 is formed in a substantially U shape, and the left and right ends thereof are connected to the rear surface of the upper frame 24, and the dust bag holder 12 is fixed and suspended on the dust box door 16 using the rear frame. . In this embodiment, a back plate 30a is installed between the left and right parts of the back frame 30, and four through holes 30b are provided in the back plate. Therefore, if this through hole 30b is used, the rear plate 30
The garbage bag holder 12 can be easily bolted to the door 16 via a. An adhesive may be applied to the back plate 30a and fixed to the door 16.

In this embodiment, the left and right parts of the rear frame 30
Since the upper end of 30c is bent inward and the rear frame has a crank shape, a gap is left between the upper frame 24 and the door 16. By leaving the gap in this way, the dust bag 22 can be easily attached to the upper frame 24.

As shown in the cutaway views and plan views of FIGS. 3 (B) and 3 (C), if a rear plate 30a 'bent in a substantially U-shape is used, the left and right portions 30c of the rear frame 30 are used. A gap is secured with the door 16 without bending.

The structure using the back plate 30a is an example,
The dust bag holder 12 may be fixed to the door 16 by another method. For example, through holes may be provided in the left and right portions 30c of the rear frame 30, and bolts may be attached using the through holes. Of course,
A method other than bolting may be used, for example, the upper frame 24 may be hung on a hook provided on the door 16 to fix and suspend the dust bag holder 12.

As described above, the dust bag 22 is attached to the upper frame 24, the bottom of the dust bag is supported by the support frame 28, the rear frame 30 is fixed to the dust box door 16, and the dust bag holder 12 is used as the dust box. Suspended at the door 16 of. Therefore, the door 16
Along with opening and closing, the dust bag holder from the dust box 10
12 can be taken out and pushed in naturally, and it is not necessary to take out and push in the garbage bag holder as an independent process. Therefore, it is possible to collect dust only by opening and closing the door 16 and exchanging the dust bag 22, which is much simpler than the conventional one, the work efficiency is improved, and the fatigue of the worker is reduced.

Further, a garbage bag holder in which the garbage bag 22 is mounted
Since 12 is put in the dust box 10 and is not exposed to the outside, the garbage bag holder does not spoil the appearance and the scenery.

In this dust bag holder 10, the dust bag 22
As a continuous type wound in a roll shape, that is, a garbage bag roll 36 is used as described above.As described above, the next garbage bag is pulled up without expanding the front and back surfaces, and the upper end is folded back. In a series of flows along the longitudinal direction of hanging on the upper frame 24, the dust bag is quickly replaced. Here, when pulling up the next garbage bag 22, the garbage bag roll 36
There is a risk of rolling over 28 and rolling off the top edge.

However, as can be seen from FIG. 3A, the lower end of the rear frame 30 extends from above the support frame 28 to the front and blocks the rolling path of the dust bag roll 36. It functions as a dust bag roll holding unit that holds the dust bag roll in a rollable and non-fallable manner, and prevents the dust bag roll from falling (rolling down).

When a plastic trash container is used, the trash container adheres and becomes dark, or is broken due to a difference in temperature. Therefore, it is necessary to clean or replace the trash container. On the other hand, in the present invention, since the dust bag holder 12 is formed of the frame body, there is no need for dust to adhere to the dust bag holder so that the dust bag holder is not blackened and there is no need for cleaning. In addition, it can be used for a long period of time without being replaced, without being damaged by the difference in temperature.

Especially, due to the elasticity of the upper frame 24, the dust bag
Since the upper end of 22 is firmly attached to prevent the dust bag from coming off the upper frame, there is no fear that dust will be put outside the removed dust bag and stain the dust box 10.

The reinforcing frame 32 includes the connecting rod 34 and the rear frame 30.
To reinforce the back frame. Therefore, the garbage bag 22
The rear frame 30 can secure the strength against the rearward bulge, and the rearward bulge is prevented.

In this embodiment, since the dust bag holder 12 is molded from the frame, the weight can be reduced, and there is no obstacle to the fixing and suspension to the door 16. In addition, the dust bag 22 is prevented from bulging in the front, rear, left, and right despite the fact that it is made of a frame. That is, by tilting the front end of the support frame 28 upward, the weight of dust is prevented from being applied to the front surface of the dust bag 22, so that the front surface is prevented from bulging. Since the left and right ends of the lower frame 26 are extended upward to form the vertical frame 26a, bulging of the left and right sides is prevented. Since the back frame 30 is reinforced by the reinforcing frame 32, bulging of the back surface is prevented.

For example, as a frame body such as the upper frame 24,
For example, a solid steel pipe is used and an iron plate is used as the back plate 30a. However, it is not limited to this, has a predetermined strength,
Other materials can be used as long as the weight of the dust bag holder 12 is not increased. Further, the frame bodies are usually connected by welding, but they may be connected by a bolt, an adhesive (bond) or the like.

Further, in the embodiment of the present invention, the upper frame 24 is illustrated as the shape having the notch 24a in the front portion, but the position of the notch is not limited to this, and other positions are provided. For example, a notch may be provided on either the left or right side or the like.

Here, when removing the dust bag 22, usually, the opening of the dust bag in which dust is stored is narrowed down,
Grasp the part with your hand and pull up the garbage bag. However, as shown in FIGS. 2 and 3 (A), in the dust bag holder 12, the vertical frame connecting the upper frame 24 and the lower frame 26 does not exist in the front portion thereof, so If you pass the narrowed part of 22 through the notch 24a in the front part of the upper frame, without pulling it up,
The dust bag can be taken out from the front of the dust bag holder 12. That is, if the notch 24a of the upper frame is provided in the front part, the dust bag 22 can be removed without pulling it upward,
The burden on the worker can be reduced, and the work efficiency at the time of garbage collection is further improved.

Here, the dust bag holder 12 described above includes the upper frame 24, the lower frame 26, the support frame 28, the rear frame 30, and the reinforcing frame, which are frame members.
32 and a connecting rod 34, and can be fixed and suspended on the inner surface of the door 16 of the dust box by bolting or the like by the back plate 30a of the back frame. However, it has an upper frame that allows the dust bag 22 to be attached and held, and the dust box door
Since it is sufficient if it can be fixed and suspended on the inner surface of 16, the dust bag holder may have the shape and configuration shown in FIGS. 5 and 6, for example.

Also in the dust bag holder 112 of the present invention,
The upper frame 124 is formed so that its circumferential length can be elastically reduced by some of the notches 124a, and each lower end frame 126a that can be used as a vertical frame is bent upward and extended. 126
, Are connected to the upper frame through the respective ends. Back frame
130 is, for example, vertically installed by fixing the upper end to the back of the upper frame 124, and the vertical portion of the dust bag support frame 127 having a substantially L-shaped side surface is arranged with the lower end bending piece 127a extending forward. The back frame and the lower frame 126 are connected by.

As can be seen from FIG. 7 in addition to FIG. 6,
In this dust bag holder 112, the lower end bent portion 127a of the dust bag roll support frame is used as a placing portion for the dust bag roll 36, and the lower end of the rear frame 130 is combined with the dust bag roll support frame 127. The trash bag roll holding means 148 that holds the trash bag roll in a rollable and non-detachable manner originally extends by bending to a position that covers the trash bag roll from the upper side to the front side.

Further, as shown in FIGS. 5 and 6, for example, a dust bag support frame 129 having a substantially S continuous shape.
However, it is arranged and fixed so as to extend to the front of the lower frame 126 so that the bottom of the dust bag 22 can be supported. The dust bag support frame 129 is formed in a slanted shape with its front end facing upward, in the same manner as the support frame 28 in the above-described embodiment so that the weight of dust collected in the dust bag 22 acts rearward. There is.

In this structure, the dust bag support frame 129 is reinforced by the connection of the connection frame 38 to the upper frame 124.

In this dust bag holder 112, the side frame 40 is provided between the rear frame 130, the vertical frame 126a and the connecting frame 38.
Are linked by The side frame 40 is, for example, the upper frame 12
The corresponding part of 4, that is, the back part to the side part is bent and formed into a substantially L shape following the shape of the upper frame, and the corresponding part is fixed to the rear frame 130, the vertical frame 126a, and the connecting frame 38 on the left and right sides. The left and right rear frames, the vertical frames, and the connecting frames are individually connected by.

As shown in FIG. 5 to FIG. 7, in this dust bag holder 112, for example, a fitting 42 is provided extending above the rear frame 130. The mounting bracket 42 is fixed to, for example, the mounting frame 42a extended upward by fixing the lower end to the rear frame 130, and the mounting bracket 42 is provided on the rear surface of the dust box door 16 so as to project therefrom. The dust bag holder 112 can be fixed and suspended on the inner surface of the door 16 of the dust box by locking the bolt 43 to the locking piece.

Also in this dust bag holder 112, the upper frame 24
Has the elasticity generated by the notch 124a, and the dust bag 22 is easily and firmly attached and held under the elasticity (see FIGS. 6 and 7). Then, as shown in FIG. 7, since the dust bag holder 112 is fixed and suspended on the inner surface of the door 16 of the dust box, the same effects as those of the above-described embodiment, such as improved workability and improved aesthetics. However, the dust bag holder of this invention can be sufficiently secured.

If the rear frame 130, the vertical frame 126a, and the connecting frame 38 are connected by the side frame 40, excessive bulging of the dust bag 22 in the back and side directions can be reliably prevented. Workability at the time of removal is improved. Furthermore, the side frame 40
The rear frame 130, the vertical frame 126a and the connecting frame 38
Since both of them are reinforced, the overall strength of the garbage bag holder is surely increased.

Reference numeral 44 in FIG. 7 is a magnet,
Reference numerals 46 respectively indicate metal plates that can be attracted to the magnets, and in the embodiment of the present invention, these combinations are exemplified as a holding means for holding the door 16 of the dust box in the closed position. The holding means is only required to be able to hold the door 16 of the dust box in the closed position, and is not limited to the combination of the magnet 44 and the metal plate 46, and other configurations such as hooks which can be engaged with each other are used. You may comprise a holding means by.

8 to 10 show another embodiment of the present invention. Also in the dust bag holder 212 of this embodiment, the upper frame 224 is formed in an elastically deformable shape having a notch 224a. Then, for example, the lower frame 226 formed in the shape of a plate is a vertical frame extending laterally in the vertical direction.
It is connected to the upper frame 224 via 226a.

In this embodiment, the vertical frame 22
There are two 6a on the left side and one on the right side. However, the number of the vertical frames 226a is not limited to this, and may be another number such as one on the left side and two on the right side. Further, the same number of vertical frames 226a may be arranged on the left and right sides, respectively.

Here, in this dust bag holder 212, the rear frame 230 is formed in a plate shape and is installed and fixed between the upper frame 224 and the lower frame 226, and the side frame 240 made of, for example, a mesh material. The back frame and the vertical frame 226a are connected by. Then, the mounting bracket 242 is integrally provided on the back portion of the rear frame 230 by screwing or the like,
As shown in FIGS. 9 and 10, the mounting bracket 242 is locked to the locking piece 16a on the inner surface of the dust box door 16, and the bolt
By tightening at 43, the dust bag holder 212 is fixed and suspended on the inner surface of the dust box door.

In this embodiment, the lower frame 22
6 is formed by integrally having an upper step portion 226b which is continuous via a slope at the front end. In such a configuration, the garbage bag 22
Since the center of gravity of the dust collected in the bag easily moves rearward along the slope continuous with the upper step portion 226b of the lower frame, the forward expansion of the dust bag is sufficiently prevented.

As can be seen from FIGS. 9 and 10, the lower frame 226 has a protruding end projecting rearward from the rear frame 230.
226c is integrally formed on the back. According to this structure, the protruding end 226c is brought into contact with the dust box door 16 so that the protruding end functions as a spacer in the back portion of the lower frame 226. When the holder 212 is fixed to and suspended from the inner surface of the door, the dust bag holder can be prevented from inclining forward, that is, falling forward.

Therefore, by providing the protruding end 226c on the back portion of the lower frame 226, it is possible to easily suspend and hold the dust bag holder 212 in a stable state without tilting forward.

As can be seen from FIG. 10, in the dust bag holder 212 of this embodiment as well, the dust bag 22 is firmly attached and held by the upper frame 224 having the notch 224a, and the dust bag is held. Since the tool 212 is fixed and suspended on the inner surface of the dust box door 16, workability is improved,
It is possible to sufficiently secure the same effects as the effects of the above-described embodiment, such as improvement of aesthetics.

The side frame 24 is provided between the rear frame 230 and the vertical frame 226a.
Since it is connected with 0, a garbage bag to the back and side
Excessive bulging of 22 is reliably prevented, and workability when removing the dust bag is improved. Furthermore, since the rear frame 230 and the vertical frame 226a are reinforced by the connection at the side frame 240, the overall strength of the dust bag holder 212 is surely increased even in this configuration.

By the way, as shown in FIGS. 8 to 10, in the dust bag holder 212 of this embodiment, the dust bag roll holding means 248 integrally provided on the lower frame 226 is provided.
Holds the garbage bag roll 36.

As can be seen from FIG. 11 in addition to FIG. 8, the dust bag roll holding means 248 may be, for example, a lower frame 226.
It has a combination of the recessed portion 50 provided in the above and a cover member 52 arranged so as to cover the recessed portion, and is formed so as to be able to roll the dust bag roll 36 and hold it in a non-removable manner.

The recess 50 of the lower frame is a cutout hole in the lower frame, and the dust bag roll 36 can be stored, for example, up to about half the radius by bending downward while leaving the front, rear, left and right peripheral edges 50a. It is formed in a concave shape.

The recess 50 of the lower frame is sufficient if it has a recess shape capable of accommodating the dust bag roll 36 at a certain depth.
The recess is not limited to the bending of the peripheral edge 50a, and the recess may be formed by other means, for example, by fitting a separate container or fixing a separate support piece. However, if the cutout hole of the lower frame 226 is formed as the recess 50 by bending the peripheral edge 50a as in this embodiment, the number of parts can be reduced and the assembly process of the recess is not required. Can be easily simplified.

The cover member 52 is formed, for example, in a substantially arc shape, and one end of the cover member 52 is rotatable with respect to the lower frame 226 by erection of a support rod 56 between a pair of support pieces 54 and pivotal support. Are linked to. The support piece 54 may be formed by cutting and raising the peripheral edge of the recess 50, for example.

Here, the cover member 52 and the lower frame 226 have a gap 58 between the dust bag roll 36 and the dust bag 22.
It is pivoted and held at the height that left it. That is, the dust bag 22 from the dust bag roll 36 can be pulled out through the insertion opening (gap) 58 formed between the lower frame 226 and the side of the pivot end of the cover member 52.

An engaging claw 60 engageable with the dust bag 22 pulled out through the insertion port 58 is provided at the center of the pivoting end side of the cover member 52. The engagement claw 60 is provided by, for example, bending downward at a position extending forward from the pivotally attached end side of the cover member 52. Then, the engaging claw 60 can be engaged with the dust bag 22 pulled upward.
Has been formed.

In the structure having such engaging claws 60, by pulling the dust bag 22 upward, the dust bag is engaged with the engaging claws, and the pulling out of the dust bag is regulated under this engagement. Therefore, at the same time when the dust bag mounted and held on the upper frame 224 is pulled up, the dust bag is automatically separated from the vicinity of the center of the perforation 22m (see FIG. 4) immediately after the seal 22s. Then, after removing the dust bag 22 containing the dust, the insertion port 58
By pulling out the next dust bag 22 from this and mounting it on the upper frame 224, the dust bag can be exchanged.

In other words, in this configuration, when the dust bag 22 in which dust is collected is pulled up, the dust bag is automatically separated, and the manual operation of separating the dust bag can be omitted, so that the dust bag can be replaced. It becomes easier and the burden on the worker can be further reduced.

In this dust bag roll holding means 248, since one end of the cover member 52 is only pivotally attached to the support piece 54 of the lower frame, the cover member also has its own free end. Then, it tries to rotate in the clockwise direction in the figure, that is, in the pressing direction against the dust bag roll 36. That is, since the weight of the free end of the cover member 52 acts on the dust bag roll 36 from above, the dust bag roll is pressed and held under the weight. Therefore, under the weight at the free end of the cover member 52, the dust bag roll 36 is sufficiently prevented from falling off.

Although the dust bag roll 36 is pressed and held by the cover member 52, the pressing force is only the turning force generated by the weight of the free end of the cover member, and therefore the dust bag 22 is pulled out. It is possible to sufficiently ensure the smooth rolling of the dust bag roll, and thus the smooth pulling out of the dust bag, without hindering the rolling of the dust bag roll accompanying the above.

Further, in this structure, the dust bag roll 36 is supported in the front, rear, left, right and up and down directions, and
Since the cover member 52 rotates in accordance with the reduction of the diameter of the dust bag roll due to the pulling out of 22, the dust bag roll can be appropriately held regardless of the reduction of the diameter of the dust bag roll.

As described above, in the dust bag holder 212 provided with such dust bag roll holding means 48, the dust bag 2
It is possible to easily secure the holding of the dust bag roll 36 suitable for pulling out the second bag, and to disconnect the dust bag automatically at the same time as pulling up the dust bag in which dust is stored. Therefore, according to the dust bag holder 212, workability when exchanging the dust bag 22 is further improved.

Here, as shown in FIGS. 8 and 9, for example, it is preferable to provide rolling means 62 below the lower frame 226 so as to rollably contact the bottom surface of the dust box 10. As the rolling means 62, for example, a radial bearing capable of supporting a load from a direction orthogonal to the rotation axis, more specifically, a ball bearing having steel balls interposed between an inner race and an outer race can be used. .

The ball bearing (rolling means) 62
If, for example, as shown in FIG. 8 and FIG. 9, a lower frame 226 is attached to a bent piece 64 that is cut and raised downward, the number of parts increases and the structure becomes complicated due to the ball bearing arrangement. Can be easily prevented.

With such a structure, when the door 16 is opened and the dust bag 22 is replaced, the ball bearing 62 rolls on the bottom surface of the dust box 10 to reduce the weight of the dust accumulated in the dust bag 22. The weight of the mounting bracket 242
It is possible to reliably prevent the dust bag holder 212 from being deformed, etc. Further, since the dust bag holder 212 is merely rotatably mounted and supported on the bottom surface of the dust box 10 via the ball bearings 62, the weight of dust accumulated in the dust bag 22 increases. Even so, the smooth opening and closing of the dust box door 16 can be sufficiently ensured.

The ball bearing 62 is mounted so as to be rollable on an arc centered on the hinge 18 of the door 16.

Here, in this embodiment, the ball bearing 62 is exemplified as the rolling means, but it is sufficient if the dust bag holder 212 is rotatably supported on the bottom surface of the dust box 10. The above means, for example, a roller or a steel ball may be used.

Further, in this embodiment, the side frame 24
Although 0 is formed from mesh material, the rear frame 230, vertical frame
Since it is sufficient to connect the 226a, it is not limited to the mesh material, for example, from the same frame body as the embodiment described above,
You may form a side frame.

However, by forming the side frame 240 from the mesh material, the back frame 230 and the vertical frame 226a can be firmly connected. In addition, the side frame 240 can be made lighter than when it is formed from a plate material.

By the way, in the embodiment of the present invention described as the dust bag holder 212, the dust bag roll holding means 248 is embodied as an integral structure with the lower frame 226. However, the invention is not limited to this, and as shown in FIG. 12, for example, the dust bag roll holder 66 that holds the dust bag roll 36 in a rollable and non-removable manner is formed as a single unit separately from the lower frame 326. However, the dust bag roll holder may be used as the dust bag roll holding means 348 by placing and locking the dust bag roll holder on the lower frame.

As can be seen by comparing FIG. 12 with FIG. 10, the basic structure of the dust bag holder 312 other than the dust bag roll holder 66 and the dust bag roll holding means 248, 348 is as follows.
It is almost the same as the garbage bag holder 212 described above,
Regarding the effect of the replacement work etc. on the garbage bag holder 312, the same contents as the garbage bag holder 212 can be obtained in the garbage bag holder 312, so the configuration, effects, etc. will not be described in detail here. .

As can be seen from FIGS. 13 and 14, the dust bag roll holder 66 is formed by a combination of a base member 68 and a cover member 70. The base member
Both the 68 and the cover member 70 are made of, for example, a synthetic resin material.

The base member 68 is, for example, a dust bag roll.
The roll 36 is rotatably stored to a certain depth, and is formed with a recess 72 capable of holding the dust bag roll under this storage. In this embodiment, the recess 72 is
It is formed in a substantially W-shaped cross section so that two garbage bag rolls 36 can be stored side by side. As can be seen from FIG. 13, in such a base member 68, the bottom surface of the recess 72 of the base member is, for example, at about 5 places for the purpose of weight reduction and reduction of the synthetic resin material. Abbreviation W
It is formed by erection of a supporting piece 72a having a shape.

The cover member 70 is formed to have, for example, an inverted W-shaped inverted recess 74 corresponding to the recess 72 of the base member, and the recess of the base member can be opened and closed. Is pivotally connected. The cover member 70
Is formed to have a pair of left and right inner protrusions 76, and is openably and closably connected to the base member 68 by loosely fitting the inner protrusions into the corresponding engaging holes 78.

Then, as shown in FIGS. 13 and 14, in this dust bag roll holder 66, a locking means 80 is provided on the free end side of the cover member 70, and the locking of this locking means allows the locking to the base member 68. The cover member can be held in the closed position. Locking means 80
For example, the extending piece 82 having a substantially U-shaped cross section extending downward from the free end of the cover member 70 and the extending piece are inserted, and the hook 82a at the tip of the extending piece is engaged with the corresponding peripheral edge. The possible combinations with locking holes 84 are illustrated here.

In such a structure, since the extending piece 82 having a substantially U-shaped cross section has elasticity, by forming the lock hole 84 in a size such that the extending piece is elastically deformed in the narrow direction and inserted. Under the restoring force of the extension piece, the extension piece hook 82a,
Engagement between the peripheral edges of the lock holes, that is, locking of the locking means 80 can be ensured.

Reference numeral 85 is an operating piece provided integrally with the extending piece 80. By pressing this operating piece toward the main body of the cover member 70, the hook 82a with respect to the peripheral edge of the lock hole 84 is fixed. The engagement can be released, that is, the lock means 80 can be released.

Here, as shown in FIG. 14, also in this dust bag roll holder 66, a gap 86 is provided between the base member 68 and the pivoting end side of the cover member 70, and this gap is the dust bag. It is used as an insertion port for pulling out the dust bag 22 from the roll 36. Then, in addition to FIG.
As can be seen from FIG. 3, the engaging claw 88 that can be engaged with the dust bag 22 pulled out from the insertion opening (gap) 86 has the cover member 70.
It extends to the center of the side of the pivot end and is integrally projected.

Here, in this embodiment, a step 90 is provided on the side of the base member 68 corresponding to the side of the pivot end of the cover member 70. The step 90 and the engaging claw 88 of the cover member are provided. By combining the above, the dust bag 22 is configured to be advanced while being bent at the insertion opening 86. In such a configuration, even if the dust bag 22 is pulled upward, the pulling out of the dust bag 22 is restricted under the refraction, so that the upper frame 22
Simultaneously with pulling up the garbage bag attached and held in 4, the garbage bag is automatically separated from the perforation 22m immediately after the seal 22s. Then, after removing the dust bag 22 in which dust has been collected, pull out the next dust bag 22 from the insertion opening 86 to remove the upper frame 22.
By attaching to 4, you can replace the garbage bag.

In other words, also in this configuration, since the work of separating the dust bag after pulling up the dust bag 22 in which dust is stored can be omitted, the exchange of the dust bag becomes easier and the burden on the worker can be further reduced. .

Then, the dust bag roll holder 66 is
As shown in FIG. 12, the dust bag holder 312 is placed on the lower frame 326, and the base member 68 is immovably locked to the lower frame by locking means (not shown) such as locking claws. It is attached as a dust bag roll holding means 348.

Even in such a dust bag roll holder 66, the cover member 70 is fixed to the base member by the locking means 80.
When held in the closed position relative to 68, the recess 72 in the base member
The dust bag roll 36 is rotatably held in the space defined by the reverse recess 74 of the cover member. And
The cover member 70 is held in the closed position by the locking of the locking means 80, so that the cover member 70 is prevented from being opened and the dust bag roll 36 is reliably prevented from falling out of the dust bag roll holder 66. So this trash bag roll holder 66
Function adequately as a garbage bag roll holding means 348.

Further, the dust bag roll holder 66 is formed as a single unit separate from the lower frame 326, and is attached to the dust bag holder 312 while being placed and locked on the lower frame. . Therefore, by simply attaching the separate dust bag roll holder 66 to the lower frame 326, the dust bag roll holding means 348
The garbage bag holder 312 having the is easily obtained. That is,
The structure of the dust bag holder itself is obtained because the dust bag holder 312 that holds the dust bag roll 36 in a rollable and non-removable manner can be obtained only by taking measures to suppress the movement of the dust bag roll holder 66 on the lower frame 326. Is simplified.

Since the dust bag roll holder 66 can be used in common regardless of the shape and size of the dust bag holder 312, the structure can be simplified in this respect as well.

Here, in this embodiment, a plurality of, for example, three steel pipe replacement support rods 92 are built in the base member 68 by erection and locking between the left and right side walls. As shown in FIG. 14, here, in the center part, 1
Two support rods 92 are arranged on the pivot side of the cover member.

In the structure in which the support rod 92 is built in, since the support rod of the steel pipe gives an appropriate weight to the base member 68, and by extension, the dust bag roll holder 66, it does not need to be firmly fixed. Easy loading and stabilization of the dust bag roll holder under locking.

The number of support rods 92, the location of the support rods, etc. are not limited to those described above, but a pulling force is likely to act upward on the side having the insertion opening 86.
That is, the support rods are arranged so that the pivot end side of the cover member 70 has a sufficient weight.

Here, the recess 72 of the base member is formed in a substantially W-shaped cross section so that the two dust bag rolls 36 can be housed and held. However, since only one garbage bag roll 36 is normally used, the recess 72 of the base member and the inverted recess 74 of the cover member are formed in a substantially U-shaped cross section capable of accommodating one garbage bag roll. You may.

However, as in this embodiment,
By forming a recess 72 of the base member and an inversion recess 74 of the cover member in a substantially W-shaped cross section capable of accommodating and holding two dust bag rolls 36, the dust bag 22 can be directly pulled out from two places. Since the free end side of the cover member 70 that is not used for the above can be used as a storage portion for the spare roll, it is possible to prevent the work efficiency from being lowered due to the dust bag running out.

In this embodiment shown in FIG. 12, the garbage bag holder 312 to which the garbage bag roll holder 66 is attached has a plate-shaped lower frame 326 as an example. The holder is not limited to a plate shape as long as the holder can be placed and locked. For example, the garbage bag roll holder may be attached to a garbage bag holder having a lower frame made of a frame.

The above-described embodiments of the present invention are for explaining the present invention, and are not intended to limit the present invention in any way, and modifications and alterations made within the technical scope of the present invention are also possible. It goes without saying that all are included in this invention.

[0120]

As described above, since the dust bag holder according to the present invention is fixed and suspended on the inner surface of the door of the dust box, the dust bag holder is naturally taken out of the dust box and pushed in as the door is opened and closed. Therefore, it is not necessary to take out and push in the dust bag holder as an independent process,
You can collect garbage simply by opening and closing the door and replacing the garbage bag. Therefore, the collection of dust is significantly simplified, the work efficiency is improved, and the fatigue of the worker is reduced.

Since the dust bag holder is formed of a frame and is lightweight, it does not interfere with fixing and suspension.

Further, the shape of the dust bag holder can prevent the dust bag from bulging to the front, rear, left, and right, and in particular, the bulge at the front face facing the back face of the dust box is prevented, so that the bulge at the front face of the dust bag is prevented. The natural opening of the door due to is surely prevented.

Furthermore, since the dust bag holder with the dust bag attached is put in the dust box, the dust bag holder and the dust collected in the dust bag will not be exposed to the eyes of the outside, and the appearance and the scenery will be improved. It doesn't hurt.

If the dust bag holder with the dust bag as described above is fixed to the inner surface of the door and a suspended dust box is used, the dust can be collected simply by opening and closing the door and exchanging the dust bag. The work efficiency is greatly simplified and the fatigue of the workers is reduced.

Since the dust bag holder is used in place of the conventional plastic and net dust containers and a part of the upper frame of the dust bag holder is cut out, elasticity is generated in the upper frame, and this elasticity is generated. Underneath, the upper end of the garbage bag is firmly attached to the upper frame. Therefore, additional work such as cleaning of the dust container, replacement of the dust container itself, and application of a rubber band is unnecessary, and from this point also, the dust collection is simplified and the work efficiency is improved.

Further, in the dust bag holder, the dust bag roll holding means for holding the dust bag roll rollably and irremovably by extending the lower end of the rear frame to a position covering the dust bag roll from the upper side to the front side. When formed, it is possible to prevent the dust bag roll from falling off due to the pulling out of the dust bag roll without inviting a complicated structure.

Further, in the structure in which the dust bag roll holding means is provided on the lower frame, not only the dust bag roll is held rollably and non-detachable, but also the dust bag can be separated at the same time as being pulled up. Also from this point, the work efficiency at the time of exchanging the dust bag is improved, and the workability is improved.

Further, in the structure in which the dust bag roll holder is used as the dust bag roll holding means, the dust bag roll is held so as to be rollable and non-detachable only by providing the lower frame with a measure for restraining the movement of the dust bag roll holder. Since the dust bag holder is obtained, the structure of the dust bag holder itself can be simplified. Since the dust bag roll holder can be used in common regardless of the shape and size of the dust bag holder, the configuration is simplified in this respect as well.

Further, according to the dust bag roll holder of the present invention, since the dust bag roll is merely stored and held in the continuous space of the concave portion of the base member and the inverted concave portion of the cover member, the dust bag roll is , Can be rolled freely and can be held properly so as not to fall off. Therefore, it is possible to easily secure the holding of the dust bag roll without hindering the pulling out of the dust bag.

Further, since the dust bag roll holder is formed under the combination of the base member and the cover member,
The configuration does not become complicated.

Further, if the concave portion of the base member and the inverted concave portion of the cover member are formed in a substantially W-shaped cross section capable of accommodating and holding two dust bag rolls, respectively, the free end side of the cover member out of two places can be formed. Since it can be used as a storage portion for the spare roll, the workability in exchanging the dust bag is improved also from this point.

Then, a step portion for advancing while refracting the dust bag pulled out from the insertion opening under the combination with the engaging claw of the cover member is provided on the base member at a position facing the engaging claw. By doing so, even if the dust bag is pulled upward, the pulling out of the dust bag is restricted by the bending of the dust bag. To be cut off from the perforation. Therefore, the work of separating the dust bag after pulling up the dust bag in which the dust is collected can be omitted, the exchange of the dust bag becomes easier, and the burden on the worker can be further reduced.

Further, in the dust bag holder, if the protruding end protruding rearward from the rear frame is provided integrally with the back portion of the lower frame,
By contacting the protruding end with the dust box door, the protruding end functions as a spacer in the back part of the lower frame. In
It is possible to prevent the dust bag holder from tilting forward, that is, falling forward.

Further, if the rolling means capable of rolling the bottom surface of the dust box is provided below the lower frame, the rolling means receives the weight of the dust accumulated in the dust bag, so that the weight is concentrated on the mounting bracket. It is possible to reliably prevent the dust bag holder from being deformed. Then, the dust bag holder is rotatably placed on the bottom surface of the dust box via the rolling means,
Since it is only supported, the smooth opening and closing of the dust box door can be ensured even if the weight of the dust stored in the dust bag increases.
