BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a storage device for a traveling wheel of a dust container, and more particularly to a device for traveling wheels of a dust container capable of stabilizing the posture of the dust container and supporting automatic collection of the dust container. Is.

[0002]

2. Description of the Related Art In order to respond to waste separation and recycling, office buildings and high-rise housings employ a waste collection device as shown in FIG.

As shown in the figure, a plurality of garbage containers 3 are installed in series in a garbage compartment 2 on the floor 1 of each floor. Combustible materials, incombustible materials, recycled garbage, etc. are classified according to their types. It is supposed to be housed. Each garbage container 3 is placed on a transfer conveyor 4 and is transferred to an elevator 5 that stops at each floor so that it can be lifted and lowered. The elevator 5 vertically conveys the waste containers 3 one by one and transfers them to the transfer conveyor 6 installed on the first floor or underground, and the container 3 on the transfer conveyor 6 is an unmanned trolley 7.
Is delivered to the storage and discharge facility 9 via the reversing device 8. The storage and discharge facility 9 includes, for example, a facility 11 for combustible waste, a facility 12 for incombustible waste, and a facility 1 for bottles according to the type of waste.
3, a can facility 14, and a paper facility 15 are provided, and the garbage in each of the facilities 11 to 15 is collected by a garbage truck, and the empty garbage container 3 is delivered to the elevator 5 via the pre-filling conveyor 16. Are collected on each floor.

As described above, since the dust generated on each floor is stored in the dust container 3 and is vertically conveyed and automatically collected, it is hygienic, and it is possible to meet the demand for collecting and recycling each type of dust. it can.

[0005]

By the way, the dust generated on the floor 1 is once put into the trolley, and this is put into the dust feeding chamber 2
Since it is inconvenient to convey the waste container 3 to the waste container 3 installed therein, it has been attempted to attach traveling wheels to the bottom of the waste container 3. If the traveling wheels are attached, the dust container 3 can be run on the floor 1, so that the dust collection efficiency and workability on each floor 1 can be improved.

On the other hand, if the traveling wheels are simply attached to the bottom of the dust container 3, the automatic transportation of the dust container 3 may be impaired when the dust container 3 is automatically collected. That is, the transfer conveyor 4 installed on each floor
Alternatively, if a roller conveyer is used as the transfer conveyer 6, unevenness is formed on the conveying surface, and the attitude of the dust container 3 becomes unstable.

Further, in an office, in order to accommodate various kinds of garbage in a narrow space, it has been attempted to install a garbage container in which one container is provided with drawers for accommodating the garbage in different stages vertically. When traveling wheels are attached to the bottom of this dust container and dust is stored only in the upper shelf, the center of gravity of the container may move upward, and the posture of the dust container may become unstable.

The present invention was devised to effectively solve the above problems, and the present invention provides a traveling wheel storage device for a garbage container which can stabilize the attitude of the garbage container and can automatically collect the garbage container. The purpose is to provide.

[0009]

SUMMARY OF THE INVENTION The present invention is an apparatus for retractably storing a traveling wheel at the bottom of a garbage cotainer, the traveling wheel having the traveling wheel, and the traveling wheel being mounted on the bottom of the garbage container to store the traveling wheel. A movably supported foot lever member, and when the traveling wheel is lowered below the container by rotating the lever member, rotation of the lever member in the storage direction is restricted and the traveling wheel is stored. The lock mechanism is configured to allow the lever member to rotate in the storage direction.

The foot lever member has a common support shaft that is pivotally supported in parallel with the bottom of the garbage container and connects a pair of lever members to each other, and at a force point portion that extends from these support shafts so as to face each other. It has a pedal which is vertically movable while connecting the force points to each other, and a traveling wheel which is guided between the pedal and the support shaft so as to be moved up and down toward the support shaft.

The lock mechanism is attached to a pedal that connects the force points of the foot lever members that extend so as to face each other, and is a hanging hole that is opened at the height position of the pedal when the traveling wheels drop below the dust container. A hook that engages with the hook to restrict rotation of the foot lever member in the storage direction, and a spring that urges the hook in the hanging hole in the removal direction.

[0012]

When the foot lever member having the traveling wheels is rotated downward against the dead weight of the dust container, the dust container is pushed up and the traveling wheels descend below it. When the rotation of the foot lever member is restricted by the lock mechanism, the dust container is held in a state in which it can travel. On the other hand, when the rotation of the foot lever member is released, the foot lever member rotates in the storage direction, and the traveling wheels are stored in the dust container.

Specifically, the foot lever members are arranged in parallel and rotate about a common support shaft connecting between the pair of lever members, and the force application points of the foot lever members extending from these support shafts are mutually made. By depressing the connecting pedal, the traveling wheels attached to the foot lever member are moved up and down. Since the traveling wheels are arranged between the pedal and the support shaft toward the support shaft side, the foot lever member can be rotated with a large lever ratio.

When the traveling wheels are stored in the bottom of the dust container, when the pedal is depressed to rotate the foot lever member downward, the traveling wheels land, and when the pedal is further depressed, the dust container moves upward. It is pushed up and the traveling wheels descend below it. When the traveling wheel descends and the hook of the lock mechanism engages with the hanging hole, the rotation of the foot lever member in the storage direction is restricted, so that the dust container can travel. When the foot lever member is further rotated in the engaged state of the hook, the hook is pushed back by the spring and disengages from the hanging hole. When the wheel is rotated in the storage direction, the traveling wheels can be stored.

An embodiment of the present invention will be described in detail below with reference to the accompanying drawings.

FIG. 5 shows a garbage container 22 which is installed on a floor 21 of an office or the like and is automatically collected through an elevator or the like. A plurality of drawers 23 are attached in the vertical direction in order to accommodate them, and traveling wheels 24 are attached to the bottom of the dust container 22.

In particular, as shown in FIGS. 1, 2 and 3, the device 31 for storing the traveling wheels 24 in a vertically movable manner has the traveling wheels 24 and rotates to store the traveling wheels 24. Four foot lever members 32, and when the traveling wheels 24 are lowered below the dust container 22 by rotating the lever members 32, rotation of the lever members 32 in the storing direction is restricted and the traveling wheels 24 are stored. It mainly comprises a lock mechanism 33 that allows the lever member 32 to rotate in the storage direction.

As shown in FIG. 3, each lever member 32 has a common support shaft 34 that connects a pair of front and rear lever members 32a and 32b and is pivotally supported in parallel with each other. Each shaft 34 is pivotally supported by a bearing block 35 on the bottom of the waste container 22. The bearing block 35 includes bolts 3 which are halved block pieces 36 and 37 that are horizontally butted against each other with the support shaft 34 interposed therebetween.
It was concluded in 8. Therefore, the common support shaft 34
A pair of front and rear lever members 32 having a depth direction are arranged so as to face each other in two pairs on the left and right.

Each lever member 32 extends from both ends of each support shaft 34 supported by the bearing block 35 so that the force points 41 face each other, and the lower front surface of the waste container 22 has a U-shaped cross section. A long hole 43 is formed on a side portion of the guide plate 42 attached so as to be opened so that the force point portion 41 of the lever member 32 is inserted and retracted and the rotation of the left and right lever members 32 is restricted within a predetermined range. . That is,
In the illustrated example, an upper edge portion 44 that partitions the upper portion of the long hole 43 to store the traveling wheels 24 restricts the rotation of the lever member 32 at a substantially horizontal position, and a lower edge that partitions the lower portion of the long hole 43. Part 4
5 allows the lever member 32 to rotate up to a height sufficient for the lower half of the traveling wheel 24 to drop below the dust container 22.

Further, the force application portion 41 extending so as to face each other has a guide plate 42 as shown in FIGS.
They are connected to each other by a pedal 46 which is guided up and down along. The pedal 46 is made of a plate material bent at a substantially right angle, and as shown in FIG. 2, a non-slip projection 48 is formed on a horizontal bent portion 47 extending in the horizontal direction, and the horizontal bent portion 47 is formed. U on the bottom of
A connecting member 49 bent in a letter shape is attached, and the force point portion 41 of the lever member 32 is inserted into the connecting member 49 and connected by a bolt 51. Therefore, in order to move the bolts 51 in the longitudinal direction of the lever member 32 and allow the pair of force point portions 41 connected by the pedals 46 to rotate, each force point portion 41 has a long hole 52 that engages with the bolt 51. Has been formed.

As shown in FIG. 4, the hook 62 of the lock mechanism 33 is provided on the upper rear surface of the lower bent portion 61 of the pedal 46.
Is attached. This hook 62 is used for the traveling wheel 24.
Guide plate 4 when is dropped below the garbage container 22
It is configured to be hooked in the hanging hole 63 opened in 2. The hanging hole 63 is opened in a rectangular shape at the height position of the pedal 46 when the lower half of the wheel descends below the dust container 22. A spring 65 having an engaging plate 64 at its tip is supported by a supporting plate 66 on the back side of the hanging hole 63. The spring 65 pushes the engaging plate 64 engaging with the hook 62 along the guide 67. The hook 62 engaged with the hanging hole 63 is biased in the detaching direction. That is, an inclined portion 68 having an upward slope facing the support plate 66 side is formed on the upper portion of the hook 62, and the inclined portion 68 is locked to the upper edge portion 69 that defines the upper portion of the hanging hole 63 to hook. While holding 62 in a hooked state,
In order to release the engaged state, the spring 65 biases and pushes the hook 64 when the hook 64 moves slightly downward.

Further, as shown in FIG. 1, the lever member 32
A wheel block 71 for holding the traveling wheels 24 is attached to the wheel block 71. The wheel block 71 is mounted between the support shaft 34 and the pedal 46 so as to be closer to the support shaft 34 in order to obtain a large lever ratio. The wheel block 71 has an upper stay 74 connected to a long hole 72 formed in the lever member 32 with a pin 73, and a lower stay 77 connected to the upper stay 74 with a male screw 75 and a knock pin 76.
Have. The lower stay 77 holding the traveling wheels 24 is guided in the vertical direction along a guide 78 fixed to the bottom of the dust container 22. Upper stay 7
A lubricant 79 such as grease is provided between the No. 4 and the lower stay 77.
Is held. Therefore, the pin 73 serves as a force application point of the lever member 32, and when the lever member 32 rotates, the traveling wheel 24 is guided vertically along the guide 78.

Next, the operation of the above embodiment will be described.

As shown in FIG. 1, the pedal 46 is depressed in order to lower the traveling wheels 24 stored at the bottom of the dust container 22 below the dust container 22 so that the dust container 22 can travel. When the pedal 46 is stepped on, the pair of lever members 32 on the front and rear in the depth direction have a common support shaft 34 and the pedals 46 connect the force application points 41 of the pair of lever members 32, so that the pedal 46 is simply stepped on. Thus, all the lever members 32 simultaneously rotate downward, and the traveling wheels 24 guided by the guide 78 can be lowered in the same direction following the rotation. If the pedal 46 continues to be depressed even after the traveling wheels 24 descend and land, the pedal 4
The weight of the dust container 22 is transmitted to 6, and the stepping force that overcomes the weight pushes up the dust container 22 and exposes the traveling wheels 24 below it. Traveling wheel 2
As shown in FIG. 4, the inclined portion 68 of the hook 62 attached to the rear side of the pedal 46 opens in the guide plate 42 while compressing the spring 65 in a state in which approximately the lower half of 4 is exposed below the dust container 22. Upper edge 6 of the hanging hole 63
The vehicle 9 is locked by 9 and is locked, and even if the stepping force is released, the traveling wheels 24 are held in a state of descending below the dust container 22, and the vehicle can travel.

On the other hand, in order to store the traveling wheels 24, the pedal 46 is further moved from the state where the hook 62 is locked in the hanging hole 63.
If you step on the hook 62, the hook 62 will be on the upper edge 69 of the hanging hole 63.
When the hook 62 moves away from the hook 62 and moves downward, a spring force is applied to the hook 62 that moves downward to restore the original state.
Therefore, when the hook 62 is pushed back to the front side in the substantially horizontal direction and the stepping force is gradually released while maintaining that state, the weight of the garbage container 22 is not caught in the hanging hole 63. Using the pedal 46
Can be raised to store the traveling wheels 24.

In this way, the traveling wheels 24 are used for the waste container 2
Since the waste container 22 is stored in the storage container 2, it is possible to maintain a stable posture even when the waste container 22 is placed on the roller conveyor, and it is possible to handle the automatic collection of the waste container 22 as well as the waste having multiple stages of drawers. In the case of the container 22, since the dust is thrown into only the upper part of the container 22, even if the center of gravity of the dust content 22 moves upward, the bottom of the dust container 22 is stored so as to cover the traveling wheels 24 and is landed. The tipping moment becomes smaller and the garbage container 22
The posture can be stabilized. In addition, the traveling wheels 24
Is the support shaft 3 between the support shaft 34 of the lever member 32 and the force point 41.
Since it is supported closer to the 4th side, a large lever ratio can be obtained, and the depression force when lowering the traveling wheels 24 can be reduced.

Further, since the hook 62 is locked or unlocked only by depressing the pedal, the traveling wheels 24 can be easily stored.

When the dust container 22 becomes heavy and a large stepping force is required to rotate the lever member 32, a spring 82 whose one end is connected to the fixing system 81 is attached to the lever member 32 as shown in FIG. The other end is connected. In this case, the lever member 32 that rotates upward is biased from above. According to this structure, when the traveling wheel 24 is lowered, the spring 82, which tends to extend, assists the stepping force by elastically urging the lever member 32, which rotates downward, toward the front in the rotation direction. On the other hand, when the traveling wheels 24 are stored, the lever member 32
Since the spring rotates against the elastic force of the spring 82 by compressing it, the shock when the bottom of the dust container 22 is landed can be alleviated. When the spring 82 is composed of an air damper, if the compressed air in the air damper is gradually extracted when the traveling wheels 24 are stored, the traveling wheels 24 can be stored slowly and the impact at the time of landing can be alleviated. Become. Further, in the above embodiment, the traveling wheel storage device 31 is installed in the waste container 2
Although it was attached to the front side of No. 2, since the force application points 41 are extended so as to face each other on the back side of the waste container 22 as well,
It is possible to attach the traveling wheel storage device 31 to the back surface, and in any case, since the pedal 46 is housed in the guide plate 42, the traveling wheel storage device 31 can be made compact.

[0029]
