Abstract

PROBLEM TO BE SOLVED: To eliminate the inconvenience of opening and closing a heavy top cover, which opens and closes in an arc, and having to separately open and closed the top cover and an upper half cover in a case where the upper half cover is provided for the front wall of a garbage container box designed for garbage collection sites. SOLUTION: The easy open and close operation of the top cover is provided, and the top cover 6 is automatically opened/closed when the upper half cover 22 is opened/closed, and vise versa, by mounting a top cover 6 in such a way that it can open and close in an arc up and down, dividing a front wall 2 into a lower half cover 21 and the upper half cover 22 so that the upper half cover 22 can slide up and down, and connecting the top cover 6 and the upper half cover 22 using a wire 8 via a sheave 7 in a way that the weight of the upper half cover 22 works to release the top cover 6. Also, the top cover remains open without being held by setting the weight of the upper half cover 22 to keep the top cover 6 open.

Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a garbage storage box installed in a garbage station for disposing of household garbage, for example. BACKGROUND OF THE INVENTION Household garbage is housed in garbage bags and housed in a garbage storage box installed in a garbage station. Most conventional garbage storage boxes have a rectangular container shape with an open top. is there. [0003] By the way, since garbage is mixed in household garbage, if a garbage bag is stored in a garbage box having an open upper part, the garbage bag from which the garbage is taken out is removed by a wild bird. In particular, crows and cats can be broken and trash inside can be scattered around, which is a problem in hygiene and beauty. As a countermeasure against such a problem, conventionally,
It has been practiced to put a protective net on the top of a trash container or to use a trash container with a top lid. [0005] However, when a protective net is put on the upper part of the garbage storage box, every time the garbage is taken out,
You have to do the work of removing the net → putting the garbage bag in the garbage storage box → re-netting,
It was troublesome to take out the trash once. Further, in a conventional garbage container with an upper lid, it is necessary to manually move the upper lid by a large amount (rotate an arc) to open and close the upper opening. The upper lid had to be held open by hand until the bag was put into the trash box, and opening and closing the upper lid was troublesome. The present invention has been made in view of the above-mentioned problems at the time of the conventional trash removal operation, and has as its object to enable a trash storage box with an upper lid to easily and easily store a trash bag in the storage box. It was done as. [0008] The present invention has the following configuration as means for solving the above-mentioned problems. still,
The present invention is mainly directed to a garbage storage box installed in a garbage station. The garbage container of the present invention is constructed by covering an upper opening of a container main body having a bottom wall, a front wall, a rear wall, and right and left side walls with an upper lid so as to be openable and closable. The size of the garbage container of the present application is not particularly limited, but the lateral width is 100 to 150 cm and the height is 90 to 100 c.
m and a width of about 80 to 90 cm can be adopted.
The bottom wall, the front wall, the rear wall, and the left and right side walls may each be a steel rectangular frame with a wire mesh stretched. The upper lid is pivotally attached to the upper end portion of the housing box main body, and is mounted so that the front side can be opened and closed by rotating vertically. The openable top cover has a large area (one piece) that can cover the entire upper opening of the housing box body.
Alternatively, a fixed upper cover may be attached to a part of the upper end of the housing box main body at the back end, and a predetermined depth width on the front side (50 to
It may be one that can be opened and closed only by a depth width of about 60 cm). The turning force in the closing direction due to the weight of the upper lid is:
The largest when the upper lid is in the closed state (horizontal posture),
There is a property that the upper lid gradually decreases as the angle of the upward rotation of the arc increases. Therefore, in the arc-rotating opening / closing type upper lid, the rotating force due to its own weight changes depending on the posture (angle) of the upper lid. The front wall is vertically divided into a lower half wall and an upper half lid. Note that the upper half lid has an area of about 1/2 of the entire area of the front wall. The upper half lid is guided by a vertically oriented guide rail so as to be slidable up and down between an upper closing position and a lower opening position. When the upper half lid is in the upper closing position, the entire front surface of the trash container is closed by the lower half wall and the upper half lid, and the upper half lid is in the lower opening position. At one time, the upper half (front opening) of the front part of the trash container is opened. When the front upper half (front opening) of the trash container is open, the front opening and the upper opening of the storage box main body are continuous without any obstruction. The upper lid and the upper half lid are connected by a wire via a sheave so that the gravity of the upper half lid acts in a direction to open the upper lid. In other words, the gravity of the upper half lid is constant and always works downward, and the gravity is used as the opening force of the upper lid via the sheave and the wire.
A pair of sheaves and wires for causing the gravity of the upper half lid to open the upper lid may be provided on both left and right sides of the trash container. The gravity of the upper half lid is set so that the posture of the upper lid can be maintained in the upper lid closed state and the upper lid opened state, respectively. That is, the rotational force in the closing direction of the upper lid is
The largest when the upper lid is in the closed position (horizontal position),
It becomes smaller as the upper lid rotates upward.
When the upper lid is in the closed position, the rotation force in the closing direction is greater than or equal to the upper lid opening operating force (constant) due to the gravity of the upper half lid, and the upper lid is maintained in the closed position. Is in the open position, the weight of the upper half cover is set so that its closing direction rotation force is smaller than the upper cover opening operating force due to the gravity of the upper half cover and the upper cover is maintained in the open position. ing. In the trash container of the present invention, the upper half opening is normally closed and the upper lid is located at the lower moving closed position, and the upper opening and the front opening of the housing box main body are respectively closed. I have. Then, when the front edge of the upper lid is lifted from this closed state, or when the upper half lid is pushed down, the upper lid is pivoted upward by the operation force, and at the same time, the upper half lid is moved along the guide rail. It descends downward, and the upper opening and the front opening of the housing box main body are simultaneously opened. still,
At the time of this opening operation, since the upper lid and the upper half-split lid are connected by a wire, the operation of only one (upper lid or upper half-split lid) also opens the other following. Also, at this time (at the time of opening the upper lid), since the gravity of the upper half lid has a function of urging the upper lid to the opening side, the upper lid opening operation force by human power is reduced by the gravity of the upper half lid. A very small one is acceptable. When the upper lid and the upper half lid are opened, a large area extending between the upper opening and the front opening of the storage box main body is opened in a continuous state, so that the garbage bag can be easily taken in and out of the storage box main body. become. In the upper lid closed state, the rotational force in the closing direction due to the own weight of the upper lid is equal to or greater than the upper lid opening operating force due to the gravity of the upper half lid, and the upper lid is maintained in the closed posture state. . On the other hand, in the upper lid open state, on the contrary, the upper lid opening operating force due to the gravity of the upper half split lid is greater than the turning force in the closing direction due to the weight of the upper lid, and the upper lid is maintained in the open posture state. Therefore, in the upper lid open state, the upper lid does not inadvertently close even if the hand is released from the upper lid. To close the upper lid and the upper half lid, pull the open upper lid downward or lift the upper half lid to connect the wires connecting the upper lid and the upper half lid. Depending on both lids (upper lid and upper half split lid)
Will simultaneously perform the closing operation while maintaining the balance. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A garbage container according to an embodiment of the present invention will be described with reference to FIGS. 1 to 6. FIGS. 1 to 5 show a first embodiment, and FIG. Two embodiments are shown. The garbage container according to the first embodiment shown in FIGS. 1 to 5 has a rectangular box-shaped container main body 10 having a bottom wall 1, a front wall 2, a rear wall 3, and right and left side walls 4, 5. It is formed and provided with an upper lid 6 at an upper opening of the housing box main body 10. Incidentally, the garbage container of the first embodiment is
Left and right width is about 150cm, height is 100cm, depth width is 80cm
The size (each dimension) of the garbage container can be changed as appropriate. A bottom wall 1 and a front wall 2 (lower half wall 2 described later)
1 and upper half lid 22), rear wall 3, left and right side walls 4,
5. The upper lid 6 is made of steel (for example, L-shaped frame)
A wire mesh is stretched in the rectangular frame of the above. The upper lid 6 has a left end and a right end of the rear end 6a attached to a rear end of the upper surface of the left and right side walls 4 and 5, respectively.
It is pivoted at 60. Therefore, the upper lid 6 is attached to the support shaft 60,
The front side (front end 6b side) of the upper lid can be opened and closed by a vertical arc around the center 60. A handle 62 is attached to the upper surface of the front end 6 b of the upper lid 6. The front wall 2 is vertically divided into a lower half wall 21 and an upper half lid 22. The upper half lid 22 has an area of about １ ／ of the entire area of the front wall 2. The lower half wall 21 is fixed to the lower front side of the housing box main body 10. The upper half lid 22 is slidably guided up and down by a pair of left and right guide rails 23 at a position close to the near side of the lower half wall 21 as shown in FIGS. A handle 26 is attached to the outer surface of the upper end of the upper half lid 22. Each of the guide rails 23 has a vertically long U-shaped guide groove 24. Each of the guide rails 23 is vertically attached to a front edge portion of an outer surface of each of the left and right side walls 4 and 5 with a guide groove 24 facing inward. Rollers 25, 25 are provided on the left and right end surfaces of the upper half lid 22 at two upper and lower positions, respectively. The upper half lid 22 is configured to connect the left and right (two each) rollers 25, 25 to the guide grooves 2 of the respective guide rails 23, 23.
4, the guide rails 23, 23
Guided to. As described above, when the rollers 25, 25 are attached to the left and right end surfaces of the upper half lid 22, respectively, when the upper half lid 22 is guided by the guide rails 23, and slides up and down, the frictional resistance between both ends is increased. And the up-and-down movement of the upper half lid 22 can be performed lightly. The upper lid 6 and the upper half lid 22 are connected by a wire 8 via a sheave 7 so that the gravity of the upper half lid 22 acts in a direction to open the upper lid 6. The sheave 7 and the wire 8 are provided as a pair on both left and right sides of the trash storage box, and are attached as follows. Each of the sheaves 7, 7 is fixed to a position slightly above the upper end of the upper half lid 22 in the upwardly closed position on the outer side surfaces near the front ends of the left and right side walls 4, 5. On the other hand,
Arms 61 are attached to the left and right end surfaces of the upper lid 6 at positions closer to the back side, respectively.
Each of the wires 8, 8 is wound around the upper surface of the sheave 7, 7, and one end 8a of the wire is connected to the arm 6.
1, while the other end 8b of the wire is fixed to the upper end of each of the left and right side surfaces of the upper half lid 22. The length of the wire 8 and one end 8 of the wire relative to the arm 61
3 and 5, the upper cover 6 is in the closed position (the position shown by the solid line) when the upper half split cover 22 is in the upper closed position (the position shown by the dotted line or the solid line), as shown in FIGS. When the upper half lid 22 is at the lower open position shown by the dashed line (reference numeral 22 '), the upper cover 6 is set to the open position shown by the dashed line (reference numeral 6'). That is, when the upper half lid 22 is in the upper movement closing position and closes the front opening 12, the upper lid 6 is in a horizontal posture and closes the upper opening 11, and the upper half lid 22 is in the lower position. When the front opening 12 is open at the moving open position (the position indicated by a dashed line indicated by reference numeral 22 '), the upper cover 6 pivots upwardly to the position indicated by the dashed line (the position indicated by reference numeral 6'). Is to be opened. As shown in FIG. 5, the upper half cover 22 is at the lower open position (position 22 'shown in dashed line), and the upper lid 6 is in the upper open position (position 6' shown in dashed line). At one time, the upper opening 11 and the front opening 12 of the storage box main body 10 are each opened continuously without any obstacles. The gravity of the upper half lid 22 is set so that the posture of the upper lid 6 can be maintained when the upper lid is closed and the upper lid is opened. That is, the gravity of the upper half lid 22 is constant irrespective of the vertical position, and a constant opening operation force is constantly applied to the upper lid 6. On the other hand, the rotational force in the closing direction of the upper lid 6 is greatest when the upper lid 6 is in the closed attitude (horizontal attitude), and decreases as the upper lid 6 rotates upward in an arc. As shown in FIGS. 3 and 5, when the upper cover 6 is in the closed position (horizontal position), the turning force in the closing direction is equal to the upper cover opening operating force (constant) of the upper half cover 22 due to its own gravity. When the upper lid 6 is maintained in the closed position and the upper lid 6 is in the open position as indicated by a chain line (reference numeral 6 ′), the turning force in the closing direction is caused by the upper half split lid 22 being opened by its own gravity. The weight of the upper half lid 22 is set so that it becomes smaller than the operating force and the upper lid 6 is maintained in the open position. As the upper lid 6 rotates upward from the closed position, the balance between the rotational force of the upper lid 6 in the closing direction and the gravity of the upper half lid 22 reverses. 6 may suddenly rotate in the opening direction. As a preventive measure, in the first embodiment, a spring 9 which urges the arm 61 in the upper lid closing direction
Is interposed. The spring 9 may be attached so as to directly urge the upper lid 6 itself in the closing direction. The trash container of the first embodiment functions as follows. Normally, as shown by a solid line in FIGS. 1 to 5, the upper half cover 22 is in the upper movement closing position and the upper cover 6 is in the lower movement closing position, and the upper opening 11 of the housing box main body 10 is closed.
The front opening 12 is closed. In this closed state, a crow, a cat, or the like cannot enter the trash container. When the handle 62 of the upper cover 6 is lifted or the handle 26 of the upper half cover 22 is pushed down from this closed state, the upper cover 6 is pivoted upward by the operation force, and The half lids 22 are guide rails 23
, And descends along the upper opening 11 of the storage box body 10.
And the front opening 12 are simultaneously opened. At the time of this opening operation, since the upper lid 6 and the upper half lid 22 are connected by the wires 8, only one operation (the upper lid 6 or the upper half lid 22) is performed, and the other (the upper half lid 22) is operated. Alternatively, the upper lid 6) is also opened. Also, at this time (at the time of opening the upper cover), the gravity of the upper half cover 22 has a function of urging the upper cover 6 to the opening side. It can be very small, with its own gravity subtracted, and can be opened lightly. When the upper lid 6 and the upper half lid 22 are opened, the storage box body 10 is opened.
Since the large-area portion straddling the upper opening 11 and the front opening 12 is opened in a continuous state, it is easy to put the garbage bag in and out of the housing box main body 10. In the upper lid closed state, the rotational force of the upper lid 6 in the closing direction due to its own weight is greater than or equal to the upper lid opening operation force of the upper half lid 22 due to its own gravity, and when the upper lid 6 is in the closed posture state. Will be maintained. On the other hand, with the top lid open,
Conversely, the upper lid opening operation force due to the gravity of the upper half lid 22 is greater than the closing power of the upper lid 6 in the closing direction due to its own weight, and the upper lid 6 is maintained in the open posture state (the state shown by a chain line). Therefore, in the upper lid open state, the upper lid is not inadvertently closed even if the user releases his / her hand from the upper lid 6, and the dust-containing bag can be taken in and out using both hands. To close the upper lid 6 and the upper half lid 22,
When the upper lid 6 in the open state is pulled down or the upper half lid 22 is lifted, both the lids (the upper lid and the upper lid) are connected by the connecting function of the wires 8 connecting the upper lid 6 and the upper half lid 22. The upper half lid is simultaneously closed while maintaining the balance. Even when the lids 6 and 22 are closed, the closing operation is performed while the respective weights of the lids 6 and 22 are substantially balanced, so that the upper lid 6 does not suddenly close. The garbage container of the second embodiment shown in FIG.
3 shows a modification of FIG. 3 in which the depth width of the upper lid 6 is reduced. That is, when the depth width of the housing box body 10 is large (for example, the depth width exceeds 80 cm), or because the front opening 12 as in the present application can be simultaneously opened, the depth side opening width of the upper opening 11 is very large. When it is not necessary to do so, the depth of the upper lid 6 can be appropriately shortened as shown in FIG. In this case, the weight balance between the upper half split lid 22 and the upper lid 6 can be maintained in the upper lid closed state (the state indicated by the solid line indicated by reference numeral 6) and the upper lid opened state (the state indicated by the broken line indicated by reference numeral 6 '). Set as follows. A fixed upper lid 6A is attached to the upper surface of the housing box body 10 at the back of the openable upper lid 6. Note that other structures in the second embodiment are as follows.
The configuration is the same as that of the first embodiment. The trash container of the present invention has the following effects. (1) Since the upper lid 6 and the upper half lid 22 of the front wall 2 can be opened and closed, respectively, the storage box main body 10 can be widely opened across the upper surface and the upper half of the front surface, The work for putting the garbage bag in and out of the storage box body 10 can be easily performed. (2) Since the upper lid 6 and the upper half lid 22 are connected by the wire 8 via the sheave 7 so that the gravity of the upper half lid 22 acts in a direction to open the upper lid 6, the upper lid 6 is opened and closed. The operating force can be reduced by the gravity of the upper half lid 22, and the upper lid 6 can be opened and closed by light work. (3) Since the upper lid 6 and the upper half lid 22 can be opened and closed at the same time by opening or closing one of them, even a garbage container having two lids, the upper lid 6 and the upper half lid 22, is provided. Only one lid (6 or 22) needs to be opened and closed, and the opening and closing operation is simplified. (4) Since the own gravity of the upper half lid 22 is set so that the posture of the upper lid 6 can be maintained in the upper lid closed state and the upper lid opened state, the upper lid 6 is maintained in the upper lid closed state. Of course, even if the user releases the upper lid 6 with the upper lid open, the upper lid 6 is not inadvertently closed, and the user can use both hands to take in and out the garbage bag.
