Multistage waste container

Technical field

TECHNICAL FIELD [0001] The present invention relates to a multistage waste container, and more particularly to a technique that is effective when applied to a waste container having a bag-like container using a resin or the like.

Background

[0002] Currently, waste generated in ordinary households or business establishments is separated according to its type in order to effectively utilize resources by reuse and to reduce the amount of waste to be processed together. For example, combustible materials that are disposed of by incineration and noncombustible materials that are not suitable for incineration and that are disposed of by landfill are collected on the date determined by the type.

[0003] In the collection, the collection vehicles of the local government circulate and collect the wastes stored in the resin bags and sent to the designated collection point. As the sachet bags used, the sachet collection bags recommended by the local government, which are called garbage bags, are used, and other stores are distributed to store the products sold. In some cases, a plastic bag is used as a plastic bag.

[0004] For this reason, at home, it is necessary to transfer waste contained in a container such as a trash can into a collection bag. Therefore, in order to save the trouble of such transfer, it is possible to attach a collection bag to the container! /

[0005] For example, Patent Document 1 listed below describes a device for holding a garbage bag made of a synthetic resin film, and it has been proposed to directly put garbage into the garbage bag using this device. Problems such as the bag falling to the bottom of the container due to the weight of the garbage, the end of the bag falling over, and the opening not being maintained, etc., resulting in the accumulation of dirt between the bag and the container, Or it can be an aesthetic problem. In order to avoid such a problem, the applicant has filed as Japanese Patent Application No. 2005-318 974 a technique capable of firmly fixing the end of the bag to the container with a simple operation.

BEST MODE FOR CARRYING OUT THE INVENTION

Hereinafter, embodiments of the present invention will be described. Note that components having the same function are denoted by the same reference symbols throughout the drawings for describing the embodiment, and the repetitive description thereof will be omitted.

FIG. 1 is a side view showing a waste container as an embodiment of the present invention, FIG. 2 is a plan view showing a frame used for the container, and FIG. 3 is a frame. It is a partial side view which expands and shows the attachment state of. In FIG. 3, for the sake of explanation, only the right half of the opening end of the bag-like storage portion 1 is shown by a broken line, and the exposed portion is hatched. In the container according to the present embodiment, the opening end of the bag-shaped container 1 for storing waste is fixed by the locking parts 3 and 4 attached to the rectangular ring-shaped frame 2 using resin. The frame 2 is fixed to the column 6 in a cantilever manner by an adjuster 5. A plurality of frames 2 are attached to the support 6 in a multi-stage manner up and down along the support 6. By arranging a plurality of storage sections 1 in a multi-stage manner in this way, it is possible to separate and store a plurality of types of waste without taking up a place for installation.

[0015] The storage unit 1 used in the present embodiment is a plastic grocery shopping bag, and an open end thereof is connected to an annular end la for use as a handle during transportation, and is connected to each other. A strip-shaped end lb is provided to face each of the two locations to prevent the tumbling. [0016] Corresponding to these opening end portions, the locking portions 3 and 4 of the frame body 2 include a fixed locking portion 3 that hooks and locks the annular end la, and a strip-shaped end portion. Movable locking portions 4 for locking lb are provided opposite to each other at two locations.

[0017] The frame body 2 has a structure in which an inner wall 2a and an outer wall 2b are integrated at an upper side 2c, and the fixed locking portion 3 partially extends downwardly from the outer wall 2b. The ring end la is hooked.

FIGS. 4 to 9 are enlarged views of the movable locking portion 4. FIG. 4 shows a side view of the unlocked state, and FIG. 5 shows a cross-sectional view thereof. FIG. 6 shows a side view before locking, and FIG. 7 shows a cross-sectional view thereof. FIG. 8 shows a side view of the locked state, and FIG. 9 shows a cross-sectional view thereof.

[0019] The movable locking portion 4 is attached to the gap between the inner wall 2a and the outer wall 2b, and contacts the slider 8 attached to the frame body 2 by the fixing pin 7 and the strip-shaped end portion lb. A stagger 9 that locks this is connected via a connecting portion 10. In the side view, in order to clearly show the slider 8, the outer wall 2b is shown by appropriately cutting away the portion.

The slider 8 is provided with an oval groove, and the shaft of the fixing pin 7 is fitted in the groove. The slider 8 rotates with respect to the shaft of the fixing pin 7 and the fixing pin 7. Can be slid with respect to the axis, and the direction and position can be changed along the inner wall 2a and the outer wall 2b.

[0021] The shaft 8a provided at the end portion of the slider 8 is fitted with a hole provided at one end of the connecting portion 10, and the hole provided at the other end of the connecting portion 10 extends from below the stagger 9. The shaft 9a provided at the side of the end force is also fitted, the shaft 9a at the end of the stopper 9 and the shaft 8a at the end of the slider 8 are orthogonal, and the stopper 9 rotates about the shaft 9a at the end. It can change direction by moving and can take a form along the inner wall 2a and the outer wall 2b and a form perpendicular to the inner wall 2a and the outer wall 2b.

[0022] In the unlocked state shown in Figs. 4 and 5, the shaft of the fixing pin 7 is located at a position away from the stopper 9 of the groove of the slider 8, so that the slider 8 is extended, so that the stopper 9 The lower end of the inner wall 2a is separated from the upper end of the strobe 9 while the gap force between the 2a and the outer wall 2b is also removed.

[0023] In the state before locking shown in FIGS. 6 and 7, the stopper 9 is rotated with respect to the shaft 9a, and the upper end of the stopper 9 is opened to the front, so that the strip-shaped end of the container 1 is opened. lb stutsba 9 and inner wall 2 Makes it easy to insert between a.

[0024] In this state, the accommodating portion 1 is placed inside the frame body 2, the accommodating portion 1 is opened along the inner wall 2a, and the opening end of the accommodating portion 1 is folded on the outer surface of the outer wall 2b of the frame member 2, After the strip-shaped end lb of the accommodating portion 1 is sandwiched between the stopper 9 and the inner wall 2a, the stopper 9 is returned to the position shown in FIGS. From this state, the stagger 9 is pushed up so that the strip-shaped end lb shown in FIGS. 8 and 9 is locked by the stopper 9.

In the locked state, the shaft of the fixing pin 7 is located near the stopper 9 in the groove of the slider 8, so that the slider 8 is in a contracted state. The distance between the fixing pins 7 is slightly smaller than the width required in a state where no force is applied, based on the dimensions of the locking portion 4, that is, the width of the stopper 9 and the connecting portion 10 and the shape of the groove of the slider 8. It is narrowed.

[0026] For this reason, by being restrained by the fixing pin 7, an elastic stress in the direction of reducing the width is generated in the locking portion 4 due to the elasticity of the locking portion 4 in the locked state. As shown in FIG. 8, in this state, the slider 8 faces the stopper 9 upward, so that an upward force is applied to the locking portion 4 by the elastic stress.

FIG. 10 is a partially enlarged longitudinal sectional view showing the relationship between the fixed portion 5 in the locked state and the bag-shaped storage portion 1. In this figure, the film thickness of the accommodating portion 1 is exaggerated for the sake of explanation.

The stopper 9 is tapered, and the shapes of the inner wall 2 a and the outer wall 2 b of the frame body 2 are determined according to the shape of the stopper 9. For this reason, the stopper 9 is fitted in a wedge shape between the inner wall 2a and the outer wall 2b of the frame 2 and the upward force described above acts, so that the stopper 9 is caused by the elastic force acting in the left-right direction in FIG. In other words, it is pressed against the inner wall 2a and the outer wall 2b.

[0029] For this reason, the strip-shaped part lb sandwiched between the stopper 9 and the inner wall 2a or the outer wall 2b is pressed by the stopper 9 and the inner wall 2a or the outer wall 2b. Even if force is applied to part lb, it will not shift. Further, the stopper 9 is made hollow so that the elastic force acting in the left-right direction in FIG. 10 is increased.

[0030] Furthermore, a step 9b that is a partial projection is provided on the back surface of the stopper 9, and this step 9b eats into the strip-shaped part lb, so that the frictional force of this part is maximized! / RU For this reason, a force is applied to the strip-shaped end lb by the weight of the contents, and the strip-shaped end lb and the stagger 9 When the part that touches the back of the plate is shifted, an upward force is applied to this part.

[0031] This force gives an upward force to the back surface of the stopper 9, which has a stronger frictional force than other portions. The upward force acting on the stopper 9 increases the pressure contact force between the stopper 9 and the frame 2. By increasing the pressure contact force against the increase in force, the strip-shaped part lb is prevented from moving. can do.

[0032] For this reason, it is possible to securely fix the end portion of the accommodating portion 1 by a simple operation of simply pushing the strip end 9 with the strip-shaped end portion lb interposed therebetween. In addition, when removing the housing part 1, it is possible to release the locked state of the end part of the housing part 1 with a simple operation by simply pushing down the stud 9.

[0033] The lower end of the column 6 to which the frame 2 is attached is fixed to the bottom frame 11, and the cap 12 is attached to the upper end of the column 6. The bottom frame 11 has a tray shape to prevent the surroundings from being contaminated when moisture leaks out of the contents or fine dust is spilled. A caster 13 is attached to facilitate the movement of the machine. In addition, it is possible to easily adjust the length of the column 6 to an optimum state by cutting it to an appropriate length.

[0034] In the present embodiment, by supporting the frame body 2 on the support 6 in a cantilevered manner, the front surface of the container is opened, waste can be easily put into the storage unit 1, and the storage that stores the waste is stored. When removing part 1, there is an advantage that it can be easily removed from the front or side of the container.

A hole is provided at a corner near the back surface of the frame body 2, and the column 6 is passed through the hole, and the adjuster 5 is tightened to fix the frame body 2 to the column 6. The frame body 2 can be moved along the support column 6, and the frame body 2 can be fixed at an appropriate height and arranged at an optimum interval.

[0036] In the support column 6, a metal pipe formed into a cylindrical shape is coated with a resin. Since the frame 2 is cantilevered, the end of the adjuster 5 comes into contact with the support 6 due to the weight of the frame 2, and the resistance of this contact portion causes the frame 2 to engage with the column 6. It can be stopped and can support some load. Therefore, the frame 2 will not fall even if it is moved up and down along the column 6 with the vicinity of the attachment part of the frame 2 and released at an appropriate position. In this state, tighten the adjuster 5 to fix the frame 2 to the support 6.

[0037] In addition, in the case of waste generated in the home, the weight of the contents is small because the weight is light compared to the volume and there are many things except for the garbage containing moisture. In this case, it is also possible to use the azimuth 5 without tightening it.

[0038] In addition, when removing the storage unit 1 containing waste, the upper storage unit 1 becomes an obstacle, and in addition, the storage unit 1 using a resin bag can contain waste. Since it deforms, it is not easy to take it out from the frame 2 upward. Furthermore, in the present embodiment, assuming that the installation is performed in a narrow place such as a side of a pillar or a side of a sink, the depth is larger than the width of the container, so that it is more difficult to take out. It is possible.

[0039] In such a case, in the present embodiment, the whole can be easily pulled out by the caster 13, and in the pulled-out state, the frame body 2 is cantilevered by the support column 6, so that the container Since the front and side surfaces of the storage unit 1 are open, it is possible to easily take out the storage unit 1 in the horizontal direction as it is by releasing the locked state of the end of the storage unit 1. At this time, using the fact that the frame 2 is easily moved up and down, in some cases, the frame 2 can be moved up and down to make it easier to take out.

[0040] When the housing portion 1 is attached, the housing portion 1 of the upper frame body 2 becomes an obstacle in the attachment to the intermediate frame body 2 except the case of the uppermost frame body 2. There is. Even in such a case, it is possible to secure the space required for mounting the housing part 1 by moving the frame body 2 to which the housing part 1 is attached or the frame body 2 positioned on the upper part, and to perform the mounting easily. Is possible.

[0041] Further, in the above description, a relatively large shopping bag is used as the housing portion 1, and the annular end la of the shopping bag is hooked on the fixed locking portion 3 to lock the strip-shaped end lb. The force that locks the to the movable locking part 4 Depending on the type of waste, a smaller-sized container may be suitable. Even in such a case, the container of the present embodiment can be applied.

[0042] For example, in a recent example of separation, it becomes a container for beverages, and is a bottle made of rosin! Therefore, it is required to separate the main body and the cap or the label with different materials in consideration of reuse. In the storage container of the present embodiment, a relatively large plastic bag is used as the storage unit 1 for storing the main body having a large volume, and the annular end la of the plastic bag is fixedly locked. A bow I is hooked on part 3 and locked, and a small plastic bag is used as the storage part 1 for storing the cap and the like inside the large plastic bag, and the annular end la of the plastic bag is movable. By engaging with the stopper 4, it is possible to perform separation by attaching two types of accommodating parts 1 having different capacities to the frame 2 of one step.

[0043] In such a case, after hooking the annular end la of the plastic bag to be the large-sized storage portion 1 on the fixed locking portion 3, the small-size storage portion is placed inside the large-size storage portion 1. Insert 1. In this state, from the state shown in FIG. 6 and FIG. 7 with respect to the movable locking portion 4, after opening the small-sized accommodating portion 1 and hooking its annular end la on both ends of the stagger 9, the stopper 9 7 is rotated downward from the state shown in FIG. 7, and the stopper 9 is turned upside down from the state shown in FIGS. 8 and 9 as shown in FIG.

From this state, the stopper 9 is pushed up, and the stopper 9 is partially fitted into the gap between the inner wall 2a and the outer wall 2b of the frame 2 as shown in FIGS. 12 and 13, and the stopper 9 is locked. It is assumed that

[0045] In the state described above, almost the entire stopper 9 was fitted in the gap of the frame 2, but in the state shown in Figs. 12 and 13, most of the stopper 9 is exposed from the inner wall 2a. A small plastic bag can be attached as the accommodating portion 1 in the short side direction of the frame 2 and opened to the width of the stopper 9. In this state, in order to prevent the annular end la of the accommodating portion 1 from coming off from the stopper 9, in the example shown in FIGS. 11 to 13, small cylindrical projections for the annular end la are provided at both ends of the stopper 9. 9c is formed in the body.

As described above, when the support 2 is deformed when the frame 2 is moved up and down, it is difficult to smoothly move the frame 2. As the deformation of the support 6, it can be considered that each frame 2 individually moves on a horizontal plane, and the support 6 is twisted on a horizontal plane perpendicular to the support 6. In order to prevent such deformation, in the present embodiment, the front portions of the bottom frame body 11 and the upper frame body 2 are connected by the front plate 14.

[0047] The front plate 14 is fitted into the groove of the bottom frame 11 and the frame 2 immediately above, and restricts the movement of the frame 2 directly above the bottom frame 2 in the horizontal direction. Yes. The front plate 14 can be provided with sufficient strength by aligning the corners of the frame body 2 so that the end portion is partly wound around the side surface. The front plate 14 integrally connects the bottom frame 11 and the frame 2 directly above and moves them individually on a horizontal plane. Therefore, it is possible to prevent deformation of each support 6 which is twisted in the horizontal plane.

[0048] If the adjuster 5 protrudes from the frame 2 with the column 6 removed, the volume of the packaged state prior to assembly increases. For this reason, in the container of the present embodiment, the protruding azimuth 5 is formed separately from the frame 2 and is stored or transported in the removed state before assembly. Is configured to be attached to frame 2.

FIG. 14 is an enlarged cross-sectional view showing the adjuster 5, and FIG. 15 is an enlarged partial plan view showing an attachment portion of the frame body 2.

The adjuster 5 uses a resin, and includes a cylindrical inner cylinder 15 fixed to the frame body 2 and a cylindrical outer cylinder 16 fitted to the inner cylinder 15. The inner cylinder 15 has four claws 15b to be fixed to the frame under the cylindrical portion 15a for penetrating the support column, and a male screw 15c is formed on the cylindrical portion 15a. On the upper side, a divided cylinder portion 15d is formed by dividing the cylinder into four in the circumferential direction, and a taper is applied to reduce the diameter in the upward direction in the figure.

[0051] The outer cylinder 16 is formed with a female screw 16a that fits with the male screw 15c of the inner cylinder 15 at the lower portion thereof, and the upper portion of the female screw 16a is a taper whose diameter is reduced in the upward direction in the same manner as the inner cylinder 15 in the figure. 16b is formed. The split cylinder portion 15d is easily deformed by the elasticity of the resin and changes its diameter, so that the female cylinder 16a of the outer cylinder 16 and the male screw 15c of the inner cylinder 15 are joined together to rotate the outer cylinder 16. As a result, the divided cylinder portion 15d of the inner cylinder 15 is tightened and deformed by the taper formed in the outer cylinder 16 and the inner cylinder 15, and the diameter thereof is reduced.

As shown in FIG. 15, the frame 2 has a cylindrical inner ring portion 2d having a hole through which the support column 6 penetrates and is integrally formed with the frame body 2 by the ribs 2e provided radially. The outer wall surface of the portion 2d, the inner wall surface of the hole 2f of the frame, and the rib 2e form an annular groove 2g divided into eight around the inner ring portion 2d, and the claws of the inner cylinder 15 are formed in the groove 2g. The inner cylinder 15 is fixed to the frame 2 by inserting 15b.

FIG. 16 is a partial longitudinal sectional view showing a state in which the adjuster 5 is attached to the frame 2. The frame 2 has upper and lower azimuths 5 attached thereto. The upper azimuth 5 shows a state in which the attachment is completed, and the lower azimuth 5 shows a state in the middle of the attachment. The four claws of each adjuster 5 are fitted into the four grooves 2g of the eight grooves 2g provided in the frame 2. The inner cylinder 15 is prevented from rotating with respect to the frame 2.

[0054] The claw 15b is turned upside down, and the inside tube 15 is removed from the frame body 2 by this turn back meshing with an annular protrusion 2h provided at the center of the groove. For this reason, simply by inserting the inner cylinder 15 into the frame 2, the adjuster 5 can be easily attached to the frame 2 without using a tool.

[0055] When the outer cylinder 16 is rotated in a state in which the support 6 is passed through the inner cylinder 15 of the adjuster 5, the split cylinder portion 15d of the inner cylinder 15 is tightened and pressed against the support 6, and the adjuster 5 is in contact with the support 6 Can be firmly fixed. In the figure, it is possible to fix the frame body 2 with only one of the forces attaching the agitator 5 to the top and bottom of the frame body 2. An appropriate configuration may be adopted depending on the required fixing strength.

Here, since the internal cylinder 15 is formed with a male screw 15c on the outer periphery, in a normal molding, the mold is divided along the center axis to perform the molding. In such molding, a linear projection called a parting line is formed at the joint of the mold divided into the cylindrical portion 15a of the inner cylinder 15.

[0057] With respect to the inner cylinder 15 of the adjuster 5, the frame 2 is cantilevered and supported by the support 6, so that it is necessary to support the load of the frame 2 and the contents. In addition, since the smooth movement is desired when the frame 2 is moved up and down, it is desirable to form with high accuracy.

For this reason, in the present embodiment, the mold is divided as shown in FIG. 17 in order to eliminate the parting line from the cylindrical portion 15a of the inner cylinder 15 that is in close contact with the frame 2. In other words, the mold 17 in the cylindrical portion is an annularly integrated mold 17, and the molds 18 and 18 divided into the left and right in the figure are used for the other portions.

[0059] By dividing the molds 17 and 18 in this way, by eliminating the parting line from the cylindrical portion 15a, accuracy is improved, and the above-described vertical movement of the frame body 2 can be realized smoothly. You can. If the inner cylinder 15 is divided in order to eliminate the parting line, the strength of the assembly portion is reduced in view of the increase in the number of processes.

[0060] While the present invention has been specifically described based on the above-described embodiment, the present invention is not limited to the above-described embodiment, and various modifications may be made without departing from the scope of the invention. Of course, this is possible.

For example, in the above-described embodiment, a bag made of greaves is used as the storage unit 1.

The same applies to the case of using other materials such as paper or cloth. In addition to storing waste, it can be used for other purposes such as storing laundry.
