Description

  The present invention relates to a trash box with a compression function that can compress trash without using power and without touching it with hands.

It is well known that if you throw away a lot of bulky garbage in the trash, the trash can fills up quickly. For example, used paper towels tend to be bulky in a trash can, so if installed in a public toilet or the like, the trash can fill up quickly. In this case, it is generally done to push the hands and feet into the trash to compress the trash in the trash, but because it is unsanitary, there are various types of trash with a function to compress the trash in the trash. Proposed.
The conventional trash can with a compression function is an automatic type that compresses using power (see, for example, Patent Documents 1 and 2), and a manual push type that compresses by operating a lever or the like without using power (for example, Patent Document 3, 4), and can be roughly classified into a stepping type (see, for example, Patent Document 5) in which a pedal is pressed down and compressed without using power. Needless to say, the automatic type is not only expensive, but also has to secure energy such as a power source. In addition, the hand-held type is also unsanitary because it requires touching the lever. Therefore, a stepping type is preferable.
However, since the conventional trash can with a stepping-type compression function uses the force of stepping for trash compression, the compression function does not work unless the pedal is depressed. Therefore, it is suitable for the form that compresses the garbage when necessary, such as when the person who wants to throw away the garbage notices that the garbage is full, but does not notice the existence of the compression function or neglects the work of stepping on the pedal It is not suitable for keeping garbage in a compressed state because there is a fear. In addition, in such a form that compresses when necessary, it is difficult to determine whether the trash can is really full because it is not possible to determine whether there is room for compression if the trash can is only full. There is also.

  Therefore, a main object of the present invention is to provide a trash box with a compression function that does not use power but is automatically exerted every time the trash is thrown away without being touched by a hand. .

The present invention that has solved the above problems is as follows.
<Invention of Claim 1>
A main body portion having a peripheral wall portion, a bottom wall portion, and a dust inlet provided at an upper portion;
A compression body provided in the main body portion so as to reciprocate toward a portion below the dust input port on the inner surface of the peripheral wall portion, and
A biasing means for biasing the compression body so as to move forward toward a portion below the dust inlet in the inner surface of the peripheral wall portion;
A pedal body attached so that it can be stepped on;
A retraction mechanism that mechanically transmits the stepping force applied to the pedal body to the compression body, and moves the compression body back against the urging force of the urging means;
A trash can with a trash compression function, characterized by comprising:

(Function and effect)
In the trash box, the space between the compression body and the peripheral wall portion located in the forward movement direction in the main body portion is a trash storage space. The trash storage space is restored by the depression of the pedal body. The volume increases due to the movement, and the volume decreases due to the forward movement of the compression body due to the release of the pedal body. Therefore, when throwing away the dust, by depressing the pedal body, the compression body can be separated from the peripheral wall portion positioned in the forward movement direction, and the dust storage space can be expanded to form the dust input space. Then, when the pedal body is released after the dust is thrown in, the compressing body is moved forward by the urging means toward a portion below the dust throwing port on the inner surface of the peripheral wall portion, the dust containing space is reduced, and the inside of the dust containing space is reduced. When the volume of the dust becomes a certain level, the dust is sandwiched between the compression body and the inner surface of the peripheral wall portion and compressed.
Accordingly, the compression function is automatically performed every time the garbage is thrown away without requiring power and touching with a hand. In addition, according to the present method, when the trash input space is not formed even if the pedal body is depressed at the time of the trash input, the trash can is full, so there is an advantage that it can be seen at a glance that the trash can is really full. .

<Invention of Claim 2>
The charging port is provided with a lid that is urged to be closed by gravity and opened by lifting against gravity,
A transmission mechanism is provided that mechanically transmits the urging gravity to the closed state applied to the lid body to the compression body so as to be the forward power of the compression body,
The urging means is constituted by the lid and the transmission mechanism.
The trash can with a compression function according to claim 1.

(Function and effect)
Thus, by configuring the biasing means of the compression body using the lid that is often provided in the trash can, the biasing force source can be omitted or simplified, and the biasing means can be provided with a lower cost and simple structure. Can do.

<Invention of Claim 3>
The compression function according to claim 2, further comprising: an opening / closing mechanism that mechanically transmits a stepping force applied to the pedal body to the lid body and lifts the lid body against gravity to open the lid body. Trash can with.

(Function and effect)
By combining the mechanism that opens and closes the lid with the pedal body in this way, when the trash is thrown in, the pedal body is depressed to open the lid and simultaneously move the compression body back to form a trash throw-in space. Then, by releasing the pedal body, the lid body is closed, and at the same time, the compression body can be moved forward in a safe state, so that dust can be compressed.

<Invention of Claim 4>
The trash can with a trash compression function according to claim 3, wherein a spring is provided as the urging means.

(Function and effect)
As described above, using the weight of the lid as the urging means is one preferable form, but since the compression force may be insufficient by itself, it is also preferable to use a spring together. In the present invention, it is not impossible to configure the urging means with only a spring, but in that case, a stronger spring is required.

It is a front view of a trash can with a compression function. It is a rear view of a trash can with a compression function. FIG. 5 is a sectional view taken along line 5-5 of FIG. FIG. 6 is a sectional view taken along line 6-6 of FIG. It is a longitudinal cross-sectional view of the trash can with a compression function of an uncompressed state (open state). FIG. 6 is a sectional view taken along line 6-6 of FIG. 1 showing another embodiment.

1 to 7 show an example of a trash can according to the present invention. The trash can 1 has a hollow pedestal portion 10 and a hollow main body portion 20 attached thereon.
The main body portion 20 includes a peripheral wall portion 21, a bottom wall portion 22, and a dust input port 23 provided at an upper portion. In the illustrated example, the entire upper surface of the main body 20 is opened as the inlet 23, but may be a part, or the dust inlet 23 may be formed in the upper part of the peripheral wall 21. The shape of the main body 20 can be determined as appropriate, and the cross section can be a known shape such as a triangular, quadrangular, other polygonal, circular or elliptical cylindrical body. Further, a shape in which the dust pressing portion on the inner surface of the peripheral wall portion 21 is a flat surface is preferable.

  The insertion port 23 is provided with a lid 24 that is urged to be closed by gravity and opened by being lifted against gravity. More specifically, the lid body 24 covers the insertion port 23, and the rear end portion 25 protrudes to the rear side of the main body portion 20, and the protruding portion 25 extends in the left-right direction (width direction) on the upper rear surface of the main body portion 20. The lid body 24 is connected to the main body portion 20 by a rotation shaft 27 passing through the shaft support portion 26 and the protruding portion 25. . The lid 24 is rotated with respect to the main body 20 around the rotation shaft 27 so as to open and close.

  On the other hand, in the main body 20, a flat plate-like compression body 30 extending in the vertical direction and the horizontal direction is moved forward and backward toward the portion below the dust inlet 23 on the inner surface of the front wall 21 f of the peripheral wall 21. It is provided to reciprocate in parallel along the direction.

  The shape of the compression body 30 is not particularly limited, such as a disc-shaped one, a rod integrated into a lattice shape, a net-like one, or a portion in which a large number of protruding portions are formed on the dust contact surface, etc. It may be. Although the size of the compression body 30 can be determined as appropriate, the dust contact area is desirably as large as possible. In particular, when a paper towel is assumed, the general disposal (rounded) dimension is about 50 mm, so the gap between the upper end of the compression body 30 and the lid 24, the lower end of the compression body 30 and the bottom wall portion 22 And the gap between the side edges of the compressed body 30 and the side wall portion 21s are preferably within 50 mm each. When a garbage bag is installed in the main body 20, even if the size of the compression body 30 is small to some extent, that is, even if the surrounding gap is large to some extent, the entire garbage can be compressed well. it can.

  In order to smoothly move the compression body 30 in a predetermined posture along a predetermined path, in the illustrated example, protrusions 31 (even with a roller having a rotation center in the left-right direction) are formed on the upper and lower portions on both side surfaces of the compression body 30. And a groove 21d through which the protrusion 31 passes is formed on the inner surfaces of the left and right side walls 21s of the peripheral wall 21 of the main body. Thereby, the attitude | position in alignment with the up-down direction is maintained for the compression body 30. FIG. Instead of such a combination of the protrusion 31 and the groove 21d, a known support structure that stabilizes the posture of the compression body 30, such as a combination of a roller and a rail, can be employed.

  It is desirable to provide a known means such as a hook for detachably fixing the garbage bag DB on the upper edge of the inner surface of the peripheral wall 21, and the fixing position is above the upper edge of the compression body 30. Is preferred.

  On the other hand, a pedal body 40 is built in the pedestal portion 10. The pedal body 40 has a U-shaped cross section in the illustrated example, and extends along the front-rear direction with a predetermined width that is narrower than the width of the main body portion 20. Openings 11 and 12 are formed on the front surface and the rear surface of the pedestal portion 10, respectively, and the front end portion of the pedal body 40 protrudes forward through the opening portion 11 on the front surface, and is a portion protruding from the pedestal portion 10. Is configured as a stepping portion 41. Further, in the pedestal portion 10, shaft support portions 13 are respectively provided on both sides of the pedal body 40 at the intermediate position in the front-rear direction. Thus, the pedal body 40 is rotated like a seesaw with respect to the pedestal 10 so that the stepping portion 41 can be stepped down.

  A first link member 50 is provided on the rear side of the main body 20 so as to be movable in the vertical direction. The first link member 50 has a U-shaped cross section in the illustrated example, and extends in the vertical direction with a predetermined width narrower than the width of the main body portion 20. The first link member 50 reaches the inside of the pedestal portion 10 via the opening 12 on the rear surface of the pedestal portion 10 at the lower side, and the lower end portion extends to the rear end portion of the pedal body 40. These first links The lower end portion of the member 50 and the rear end portion of the pedal body 40 are connected so as to be rotated by a rotation shaft 51 penetrating them in the left-right direction. Further, the upper end of the first link member 50 is configured to come into contact with a portion of the bottom surface of the lid body 24 that is in front of the rotation shaft 27 of the lid body 24. Accordingly, when the foot part 41 of the pedal body 40 is stepped down, the rear end part of the pedal body 40 is raised, and accordingly, the first link member 50 is raised to push up the lid body 24 and open the lid body 24. Can be. In this state, if the foot is released and released from the stepping portion 41 of the pedal body 40, the first link member is lowered by the weight of the lid body 24 and the first link member 50, and the rear end portion of the pedal body 40 is lowered accordingly. Then, the front end part rises and the pedal body 40 is naturally returned to the original position.

  Characteristically, the 2nd link member 60 is extended from the upper end part located above the main-body part 20 in the 1st link member 50 to the rear surface of the compression body 30 through the insertion port 23. FIG. In the illustrated example, the second link member 60 is made of a round bar, and is provided in a pair on the left and right. And the rear-end part of the 2nd link member 60 is bent toward the center in the left-right direction, and the front-end | tip is each inserted in the insertion hole 52 provided in the both sides | surfaces of the 1st link member 50, respectively, The first link member 50 is connected so as to rotate about the left-right direction. In addition, the front end portion of the second link member 60 is also bent toward the center in the left-right direction. By being inserted respectively, it is connected to the compression body 30 so as to rotate about the left-right direction. And the intermediate part of these front-end parts and rear-end parts is bent and extended so that the surrounding wall part 21 inner surface may be met.

  As described above, when the first link member 50 and the compression body 30 are connected via the second link member 60, the lid body 24 and the compression body 30 are released in a state in which the pedal body 40 is released to close the lid body 24. When the lid 24 is closed by the weight of the first link member 50 and the first link member 50 is pushed down, the biasing force is applied not only to the pedal body 40 but also to the compression body 30 via the second link member 60. The compression body 30 is urged in the forward movement direction. That is, the urging means of the compression body 30 is configured by the lid body 24 and the transmission mechanism.

  Instead of or together with this urging means, the compression body 30 can be urged in the forward movement direction using a spring 70 as shown in FIG. In the illustrated example, the front wall 21f and the compression body 30 of the peripheral wall portion 21 of the main body 20 are connected to each other by coil springs 70 on both the left and right sides, and the compression body 30 is pulled toward the front wall 21f. However, the present invention is not limited to this, and various springs are provided so as to urge the first link member 50 downward, or the rear side of the pedal body 40 is lowered from the rotating shaft 14 or the front side is raised. It is also possible to provide a spring or to combine them. As the spring 70, a compression coil spring, a tension coil spring, a torsion coil spring, a leaf spring, a spring spring, a bamboo shoot spring, and the like can be appropriately selected and used depending on the usage form.

  As described above, when the pedal body 40, the first link member 50, and the second link member 60 are linked, when the pedal body 40 is stepped down, the step-down force increases to the first link member 50. This is transmitted as a force, and the upward force of the first link member 50 is transmitted as a force that pulls the second link member 60 rearward and obliquely upward. It is transmitted to the compression body 30 as a motive power. Therefore, in the illustrated example, the pedal body 40, the first link member 50, and the second link member 60 constitute a backward movement mechanism that causes the compression body 30 to move backward against the urging force in the forward movement direction. .

  In the trash box 1 configured as described above, the space between the compression body 30 and the front wall 21f located in the forward movement direction in the main body portion 20 is a trash storage space. The volume increases or decreases as the pedal body 40 is stepped down and released. More specifically, when throwing away garbage, the pedal body 40 is depressed as shown in FIG. As a result, the first link member 50 is raised, the lid body 24 is pushed up and opened, the rear end portion of the second link member 60 is raised, and the compression body 30 is moved backward by the rear component of the rising force. Then, the compression body 30 is separated from the front wall 21f located in the forward movement direction. As a result, the dust storage space is expanded, and a surplus space for dust input is formed. When the pedal body is released after the dust D is thrown in, the first link member 50 is lowered by the gravity applied to the lid body 24 and the first link member 50 and the lid body 24 is closed. The rear end portion of the member 60 descends, and the compression body 30 moves forward toward the front wall 21f by the front component of the descending force. As a result, as shown in FIG. 1, when the dust storage space is reduced and the volume of the dust D in the dust storage space is a certain level, dust is collected between the compression body 30 and the inner surface of the front wall 21f. It is sandwiched and compressed. Accordingly, the compression function is automatically performed every time the garbage is thrown away without requiring power and touching with a hand. Moreover, according to the present system, it can be seen that the trash can is full at a glance when the trash input space is not formed even if the pedal body 40 is depressed when the trash is input.

  In addition, the form which reciprocates the compression body 30 toward the part below the dust inlet 23 in the inner surface of the surrounding wall part 21 is not limited to the form in which the compression body 30 is translated as in the above example. Reciprocation by other movement paths, such as a form in which the compression body 30 is rotated toward the inner surface of the peripheral wall portion 21 by pivotally supporting the lower end portion of the shaft 30 with respect to the main body portion 20 so as to rotate about the left-right direction. A moving form is also included.

  Further, the mechanical force transmission mechanism in the urging means and the backward movement mechanism is not limited to the above example, but a known rotation mechanism or reciprocation mechanism using a gear, a crank, a cam, a shaft (shaft), or the like. The rotation / reciprocating mechanism can be used.

  The present invention is suitable as a trash box for disposable paper products such as paper towels, but of course can be applied to trash boxes in general.
