2. Description of the Related Art A conventional waste disposal apparatus which is of interest to the present invention is described in, for example, Japanese Patent Application Laid-Open No. Hei 1-2226601. The waste disposal apparatus described here uses a flexible tube to wrap the waste in a sealed state. The tube is unwound from a cassette having a specific structure, and is twisted each time waste is received, thereby preventing a bad smell from being released to the outside. When filth is sequentially stored in such a tube, the filth takes the form of intestinal sausage and is discarded together with the tube.

[0003]

However, in the above-mentioned waste disposal apparatus, a cassette having a specific structure must be used in order to feed out a tube for wrapping the waste. Therefore, when using this waste disposal equipment,
There is a problem that the cost of consumables is relatively high. Also, such cassettes are often only available through a particular sales channel, and thus encounter the problem of inaccessibility.

It is therefore an object of the present invention to provide a waste disposal apparatus which can be used with consumables which are extremely easily available.

[0005]

In the waste disposal apparatus according to the present invention, a flexible bag is used to store waste. In order to enable use of such a flexible bag, the waste disposal apparatus according to the present invention has the following configuration.

That is, a waste disposal apparatus according to the present invention has a housing having an upper opening, a lid rotatably supported by the housing to close the opening so that the opening can be opened and closed, and a housing disposed inside the housing. a fixing mechanism FLEXIBLE of releasably securing the peripheral edge of the opening in a state where the opening of the open bag, and a closing control mechanism is operated the bag in a closed Jill so at a position below the fixing mechanism.

[0007] Further, the above-mentioned closing control mechanism comprises the following steps:
A first rigid link capable of reciprocating in first and second directions opposite to each other, and (b) operating in conjunction with each reciprocating movement of the first rigid link, The first rigid link is operated to close the bag in association with the movement in the first direction, and is operated in conjunction with the movement in the second direction to allow the bag to be opened.

The first rigid link includes an elastically displaceable first engaging portion that engages with the fixed portion at an end of the first rigid link so as to move with the first rigid link in the second direction. A moving member having a second engaging portion to be engaged; and (f) applying a spring force larger than the first spring, and urging the moving member to move in the second direction. And (g) at the end of the movement of the moving member in the second direction, disengaging the moving member so that the second engaging portion is disengaged from the first rigid link. A guide member for guiding; and (h) the first engagement provided on the lid according to a closing operation of the lid. Displaces the releasing the engagement of the first engagement portion to the fixed portion, and a disengagement member.

[0008]

According to the present invention, a flexible bag for wrapping filth is disposed in the housing. In this state, the periphery of the opening of the bag is fixed by the fixing mechanism, and the opening of the bag is opened. Then, in order to prevent the odor from the filth housed in the bag from being released to the outside, the opening of the housing is closed by the lid, and at a position below the fixing mechanism, the bag closing member provided in the closing control mechanism is Close the bag.

As described above, the waste disposal apparatus according to the present invention is usually placed indoors with the bag closed by the bag closing member at a position below the fixing mechanism and the opening of the housing closed by the lid. . Then, when newly putting waste into the bag, the operation is performed in the following procedure.

That is, first, the lid is opened, and in that state,
The waste is placed in the area surrounded by the periphery of the opening of the bag secured by the securing mechanism. Thus, when the lid is opened, the distal end of the second rigid link is moved in the first direction according to the operation. Along with the movement in the first direction, the distal end of the second rigid link engages with the moving member, and moves the moving member in the first direction. Due to the movement of the moving member in the first direction, energy for moving the moving member in the second direction is stored in the second spring. Further, at the end of the movement of the moving member in the first direction, the first engaging portion is engaged with the fixed portion, and the position of the moving member is maintained despite the bias by the second spring. .

Next, the lid is closed. Accordingly, in the waste disposal apparatus according to the present invention, the energy stored in the second spring described above is firstly set such that the bag closing member is allowed to open the bag based on the operation described below. Activated, the filth that had been placed in the area surrounded by the periphery of the opening of the bag as described above falls into the bag,
The bag closing member is then operated to close the bag. That is, in accordance with the closing operation of the lid, the disengagement member provided on the lid displaces the first engagement portion, and the engagement of the first engagement portion with the fixed portion is released. This allows the moving member to move the second spring based on the energy stored in the second spring.
Is moved in the direction of. The movement of the moving member in the second direction causes the first rigid link to move in the second direction because the second engaging portion engages with the first rigid link. The movement of the first rigid link in the second direction proceeds against the elasticity of the first spring, so that part of the energy stored in the second spring is reduced by the first spring. Is stored in
Further, in conjunction with the movement of the first rigid link in the second direction, the bag closing member is operated so as to be in a state allowing the bag to be opened. At this stage, the dirt falls into the bag, as described above. In this way, when the moving member moves in the second direction and reaches its end, the guide member
The engagement of the second engagement portion with the first rigid link is released. Accordingly, the first rigid link is moved in the first direction based on the energy stored in the first spring described above. In conjunction with the movement of the first rigid link in the first direction, the bag closing member operates to close the bag. Here, the bag is closed again. Thus, a series of operations during normal use of the waste disposal apparatus is completed.

[0012]

As described above, according to the present invention, the waste disposal apparatus can be continuously used only by using a flexible bag as a consumable. As such a bag,
Since a commercially available bag made of polyethylene or polypropylene can be used as a garbage bag as it is, the cost of consumables can be extremely reduced, which is economical and easy to obtain.

Further, the waste disposal apparatus is automatically operated such that the bag closing member once allows the bag to be opened and then closes the bag according to the operation of closing the lid. Therefore, the operation for putting the waste in the bag is extremely simple, and the waste can be handled cleanly.

Further, when trying to put new waste into the bag, when the lid is almost closed, or when the lid is completely closed, the bag is opened to accept the new waste. Since it is not too long, the odor emitted from the waste in the bag can be minimized from leaking out of the housing.

It should also be noted that the waste disposal apparatus according to the present invention can be operated without requiring power supply. For this reason, the safety can be extremely increased, and the installation location can be selected.

The moving member 41 includes a first engaging portion 43 that engages with a pin-shaped fixing portion 42 provided on the frame 16 at the end of the movement in the first direction 30 as shown in FIG. 2. The first engagement portion 43 is elastically displaceable with respect to the main body of the moving member 41, as can be seen, for example, by comparing FIGS. 1 and 3. When the moving member 41 is made of, for example, a resin, the elasticity of the resin itself can provide such an elastically displaceable configuration.

The moving member 41 also has a second direction 31.
In order to make the movement accompany the first rigid link 25 when moving to the second direction, a second engaging portion 44 that engages with the first rigid link 25 is formed. In FIGS. 2 and 3,
The second engagement portion 44 is engaged with the first rigid link 25, and such engagement does not occur in FIG. 1 and FIG.

The moving member 41 is movable in the first and second directions 30 and 31 along a guide portion 45 provided on the first rigid link 25, and is slightly displaceable in the vertical direction. . The state where the second engaging portion 44 is engaged with the first rigid link 25 described above occurs when the moving member 41 is displaced downward.

The moving member 41 moves in the second direction 3
It is urged by the second spring 46 to move to 1. The second spring 46 is in the form of a tension spring in this embodiment, and has a fixed pin 47 provided on the frame 16.
And the moving member 41. The fixing pin 4
The position of 7 is chosen such that the second spring 46 urges the moving member 41 to displace slightly downward. this is,
This is to ensure that the engagement of the second engagement portion 44 with the first rigid link 25 described above occurs more reliably. Also,
As the second spring 46, a spring that gives a larger spring force than the first spring 36 described above is used.

At the end of the movement of the moving member 41 in the second direction 31, the engagement of the second engaging portion 44 with the first rigid link 25 is released. Therefore, for example, a guide member 48 having a gradient is provided so as to contact the lower end of the moving member 41. 1 and 4, the moving member 41 is guided by the guide member 48 and slightly displaced upward, whereby the engagement of the second engagement portion 44 with the first rigid link 25 is released. It is shown.

The lid 7 is provided with an engagement release member 49. The disengagement member 49 displaces the first engagement portion 43 in accordance with the closing operation of the lid 7 to disengage the first engagement portion 43 from the fixing portion 42 as shown in FIG. Act like so.

As described above, the pair of bag closing members 14 and 15 can be moved toward and away from each other, and such an operation is achieved by the rotation of the drive shafts 21 and 22 in the opposite directions. Is done. The drive shafts 21 and 22 and the bag closing members 14 and 15 are respectively
As shown in FIG. 5 to FIG.
Connected by 0 and 51. More specifically, the connecting links 50 and 51 include arms 52 and 53 integrally extending from the drive shafts 21 and 22, arms 54 and 55 integrally extending from the bag closing members 14 and 15, and arms 52 and 53 and the arms. Pins 56 and 57 for rotatably connecting the pins 54 and 55 to each other are provided. Thus, in order to transmit the rotation of the drive shafts 21 and 22 to the bag closing members 14 and 15, respectively,
The use of the bendable connecting links 50 and 51 requires a relatively small space for operating the bag closing members 14 and 15, thereby preventing the waste disposal apparatus 1 from being enlarged.

FIG. 8 is an enlarged sectional view showing a pair of bag closing members 14 and 15 which are in close proximity to each other. As shown in FIG. 8, the bag closure members 14 and 15 preferably have mating surfaces 58 and 59 that fit together.
Are respectively formed. Thus, when the pair of bag closing members 14 and 15 sandwich the bag 8, the tightness of the closed bag 8 can be further improved. In order to further enhance the airtightness, it is also effective to configure at least the surfaces of the bag closing members 14 and 15 with an elastic material such as rubber.

In such a configuration, the closing control mechanism 1
3 is operated as follows. First, in FIGS. 1 and 5, the closed state of the bag 8 is realized. In this state,
A pair of bag closing members 14 and 15 are close to each other, and close the bag 8 by sandwiching the bag 8 from both sides of the bag 8. On the other hand, in the state shown in FIGS.
Is open. Such a state is realized in accordance with the operation of closing the lid 7 once opened, and thereafter, the bag 8 is returned to the closed state shown in FIGS. 1 and 5 again.

More specifically, first, the lid 7 is opened from the state shown in FIG. 1 as shown in FIG.
Thereby, the distal end portion 39 of the second rigid link 37 is
While moving in the first direction 30 along the guide slot 40, it engages with the moving member 41, and moves the moving member 41 against the elasticity of the second spring 46 in the same first direction 30. Move to At the end of the movement in the first direction 30, the first engaging portion 43 provided on the moving member 41 engages with the fixed portion 42, and the moving member 41 is prohibited from returning in the second direction 31. , Whereby energy is stored in the second spring 46. Further, the moving member 41 is slightly displaced downward, and the second engaging portion 44 is moved to the first rigid link 25.
Is engaged.

Next, when the lid 7 is closed, first, as shown in FIG. 3, the disengagement member 49 comes into contact with the first engagement portion 43, and the first engagement portion 43 is moved downward. To be displaced. Thereby, the engagement of the first engagement portion 43 with the fixing portion 42 is released. Also, the tip 3 of the second rigid link 37
9 moves away from the moving member 41 and moves in the second direction 31.

As described above, the first portion with respect to the fixing portion 42
When the engagement of the engagement portion 43 is released, the second spring 46
The moving member 41 is immediately moved in the second direction 31 based on the energy stored in the moving member 41. This movement causes the first rigid link 25 to move in the second direction 31 because the second engagement portion 44 is engaged with the first rigid link 25. Thus, the first rigid link 25 is
When the pinions 23 and 24 move in the direction 31
Are arrows 60 and 61, respectively, as shown in FIG.
Rotated in the direction. Due to the rotation of the pinions 23 and 24, as shown in FIG. 6, the connecting links 50 and 51 are respectively bent in an inverted V shape, and the pair of bag closing members 14 and 15 are separated from each other. . This allows the bag 8 to be opened.

The above-described movement of the first rigid link 25 in the second direction 31 is realized based on the energy stored in the second spring 46 that gives a stronger spring force. The movement of the first rigid link 25 is controlled by the first spring 3
6 progresses against the elasticity. Therefore, the first spring 36
, A part of the energy stored in the second spring 46 is stored. At the end of the movement of the moving member 41 in the second direction 31, the moving member 41 is guided by the guide member 48 and is slightly displaced upward. As a result, the engagement of the second engagement portion 44 with the first rigid link 25 is released. When the engagement is released in this manner, the first spring 3
Based on the energy stored in 6, the first rigid link 25 immediately moves in the first direction 30. This first
The rigid link 25 rotates the pinions 23 and 24 in the directions opposite to the arrows 60 and 61, respectively.
As shown in FIG. 5, the connecting links 50 and 51 are linearly extended, and the bag closing members 14 and 15 are close to each other. Thus, the bag 8 is closed again by being sandwiched between the bag closing members 14 and 15.

In this way, the state returns to the state shown in FIG. 1 again, and thereafter, each time the lid 7 is opened and then closed, the above-described operation is repeated.

Next, a method of using the waste disposal apparatus 1 will be described. First, at the start of use, the bag 8 is mounted in the housing 3. Therefore, the bag 8 is extended so as to reach the lower portion 5 of the housing 3 by opening the lid 7 and forcing the pair of bag closing members 14 and 15 apart from each other. On the other hand, the peripheral edge 9 of the opening of the bag 8 is located above the ring-shaped edge 11,
, The ring-shaped member 12 is fitted therein, and the peripheral portion 9 of the bag 8 is fixed.

In the above-mentioned state, the waste disposal apparatus 1 is ready for use, and the lid 7 is preferably kept closed until waste disposal becomes necessary.

When filth to be treated by the filth treatment apparatus 1 is generated, the lid 7 is opened and the filth 62 is thrown in from above the opened opening of the bag 8 as shown in FIG. As shown in FIG. 5, the waste 62 is placed in a region surrounded by the peripheral edge 9 of the opening of the bag 8.

Next, the lid 7 is closed as quickly as possible. As a result, the operation of the closing control mechanism 13 described above proceeds, and when the pair of bag closing members 14 and 15 are separated from each other, the dirt 62 moves toward the bottom of the bag 8 as shown in FIGS. 4 and 6. And fall. The pair of bag closure members 14 and 15 are then in close proximity to each other and again, FIG.
As shown in FIG. 5 and FIG. 5, the bag 8 is closed, and waits until the next filth is generated.

The operation procedure as described above is repeated, and the bag 8
Are filled with dirt 62, these dirt 62
Is discarded together with the bag 8. In this case, first, the lid 7 is opened, and then the ring-shaped member 12 is removed. Then, the peripheral edge 9 of the opening of the bag 8 is bound by, for example, winding an adhesive tape. Thereafter, the bag 8 is removed from the housing 3 while forcing the pair of bag closing members 14 and 15 away from each other. At this time, the upper part 4 of the housing 3 is separated from the lower part 5 and
The bag 8 accommodating 2 may be carried to a predetermined place while being received by the lower portion 5.

Although the present invention has been described with reference to the illustrated embodiment, various other modifications are possible within the scope of the present invention. For example, the securing mechanism 10 may be provided by a structure other than the structure shown. Further, the bag closing members 14 and 1 are connected to the first rigid link 25.
Motion-transmitting mechanism leading to 5 may be replaced with other structures, also, the bag closure member 14 and 15, the bag 8 may be replaced by that of closing Gilles structure by other operations.
