Description

The present invention relates to a trash can having a pedal-type left / right opening / closing lid.

Conventionally, various trash cans having a pedal-type opening / closing lid have been proposed. U.S. Pat. No. 4,862,214 is provided with a container having an upper opening, a lid attached to the container that swivels around a swivel axis to open and close the upper opening, and a mechanism that makes the lid rotatable. This mechanism has a pedal portion, a lid flange integrally coupled to the lid, and a rod connecting body for connecting the pedal portion and the lid flange to each other. Also, the lid flange has elongated holes formed through its thickness. The elongated hole has a channel and two enlargements located at both ends thereof. According to this trash can, by stepping on the pedal section, the pedal section rotates and the rear end moves upward, pushing up the rod coupling, which causes the upper end of the rod coupling to pass through the channel and two. By locking to one of the enlarged portions, the lid flange rotates, and the lid opens accordingly.

U.S. Pat. No. 4,862,214

However, in a trash can having a pedal-type opening / closing lid, the lid usually opens substantially upright during use. Therefore, an upper space is required to allow the lid to open. Household trash cans are usually placed in the corners of the room. Even in this case, a certain installation area for placing the trash can is required. The installation position of the trash can is determined by various factors such as the convenience of the installation location, the usability and taste of the user, and among them, when it is installed in a place where the upper space is limited, such as under a desk or a shelf. There is. In this case, the trash can having the pedal-type opening / closing lid has a problem that the lid is half-opened and cannot be practically used. Further, the conventional trash can has a problem that the operation reaction of the lid by depressing and releasing the pedal is not always quick.

Therefore, an object of the present invention is to provide a trash can having a pedal-type opening / closing lid that can be used even in a place where the upper space is limited by smoothly opening and closing the lid and quickly responding to the movement of the pedal.

In such a situation, as a result of diligent studies by the present inventor, if one opening / closing lid is divided into two to form a double-opening lid having a specific structure, the lid can be opened and closed smoothly and the height of the upper space can be increased. We have found that it can be reduced by half, and have completed the present invention.

That is, in the present invention, the trash container having an upper opening, the pedal portion rotatably attached under the trash container in a seesaw shape, and the upper opening of the trash container can be opened and closed in both left and right directions. It has a pair of attached lids and a connecting body that connects the rear end of the pedal portion and the pair of lids on the rear side of the trash can, and is on the back surface of the lid on the rear side of the trash can. Each of the locking projections having a locking hole for locking the locking round bar portion of the connecting body is formed, and the lower end of the connecting body extends in the vertical direction rotatably connected to the rear end of the pedal portion. It has a vertical portion and a locking round bar portion that is located above the vertical portion and extends in the forward direction of the trash container. By stepping on the pedal portion, the connecting body is lifted upward and the lid is opened on both sides. By releasing the depression of the pedal portion, the connecting body is lowered downward and the lid is closed to provide a trash can.

Further, in the present invention, the lid is a right lid having the same shape as the left lid of the plate-shaped body when viewed in a plane, and the left lid is counterclockwise in front view near the upper end of the garbage storage container. The right lid is rotatably attached to the trash can, and the right lid is rotatably attached clockwise in the front view in the vicinity of the upper end of the trash container.

Further, in the present invention, the lid has a top plate, left and right side plates, and front and rear side plates, and locking protrusions are formed on the front and rear side plates, respectively. The present invention provides the trash can, characterized in that a locking recess for movably locking is formed.

Further, in the present invention, the connecting body has a horizontal round bar portion extending in the left-right direction connected to the upper end of the vertical portion, and the locking round bar portion has both tip portions of the horizontal round bar portion bent. The trash can is provided, which is characterized in that it extends forward.

Further, in the present invention, the locking hole is a long hole long in the vertical direction in the closed state, and the upper end and the lower end are rounded, and the upper rounded shape is gentler than the lower rounded shape. It provides the trash can characterized by being curved rounded.

According to the present invention, in a place where the upper space is limited, it is sufficient to have half the upper space as compared with the conventional single-sided lid trash can, and the selection of the place where the upper space can be used is widened. In addition, the lid can be opened and closed quickly and smoothly by stepping on and releasing the petal portion.

Next, the trash can according to the embodiment of the present invention will be described with reference to FIGS. 1 to 12. In the present specification, "left and right" and "front and back" refer to the direction in which the pedal portion is viewed as the front (front) side.

The trash can 10 can be opened and closed by opening and closing the trash storage container 1 having an upper opening, a pedal portion 3 rotatably attached under the trash storage container 1 in a seesaw shape, and the upper opening of the trash storage container 1. It has a pair of lids 2 (21a, 21b) to be attached, and a connecting body 4 for connecting the rear end 33 of the pedal portion 3 and the pair of lids 2 on the rear side of the garbage container 1. In the garbage storage container 1, dust is thrown in through the upper opening of the open door 2.

The garbage storage container 1 has a container body 11. In the container main body 11, the shape of the edge portion in the vicinity of the upper opening is not particularly limited as long as the shape is such that a pair of lids 2 having a rectangular shape in a plan view and a plate-like body are installed. That is, the outer dimension of the upper end of the container body 11 is the same as the outer dimension when the pair of lids are installed side by side with almost no gap in a plan view. That is, the upper end surface formed by the thickness of the container body 11 and the back surface of the pair of lids 2 come into contact with each other, whereby the container body 11 supports the pair of lids 2.

In the garbage storage container 1, upper front and rear upright portions 12a and 12b are formed on the front and rear side portions of the upper end of the container main body 11 so that the height extending upward from the container main body 11 is substantially the same as the thickness of the lid. Further, on the inside of the upper front and rear upright portions 12a and 12b, and on the left and right ends, locking recesses (four convenient locations) 14 to which the locking convex portions 22 of the lid 2 are locked are formed. As a result, the locking convex portion 22 attached to the lid 2 is locked in the locking recess 14, allowing the lid 2 to be opened and closed freely from side to side, and the lid is installed between the upper front and rear standing portions 12a and 12b. Will be. The locking recess 14 is a round hole in this example. Further, in this example, the container body 11 is a quadrangular box-shaped body that is slightly thin toward the bottom. As a result, the protrusion of the pedal portion 3 from the container main body 11 to the front is suppressed, and the installation stability is excellent without sacrificing the storage volume. Further, a space (notch portion) 16 having an L-shaped cross section through which the pedal portion main body 32 and the connecting body 4 pass is formed on the back side of the back plate of the container main body 11 and the back side of the bottom plate. As a result, the locking round bar portions 43, 43 of the connecting body 4 can be locked to the locking holes 51, 51 of the locking projections 5, 5 formed on the back surfaces of the lids 21a, 21b. Further, a through hole 15 through which the connecting body 4 passes is formed in the upper part of the back plate of the container body 11 (see FIG. 3). Further, shaft holes 18 and 18 through which a shaft 34 that rotatably supports the pedal portion main body 32 passes are formed in the bottom portion of the container main body 11 (see FIG. 4). Further, a damper storage hole 17 for accommodating the damper 9 is formed on the back side of the front plate of the container body 11 (see FIG. 8).

The pair of lids 2 is a plate-shaped left lid 21b and a right lid 21a having the same shape when viewed from a plane, and the left lid 21b is rotated counterclockwise in front view near the upper end of the garbage storage container 1. The right lid 21a is movably attached, and is rotatably attached clockwise in front view near the upper end of the dust storage container 1. In this example, the left lids (right lids) 21a and 21b have a top plate, left and right side plates, and front and rear side plates 27, 27, and have a rectangular shape in a plan view and a shallow bottom lid shape with the back side hollowed out. Further, on the back surface of the lid 2 on the rear side of the dust storage container 1 and on the outer side in the left-right direction, a locking projection 5 having a locking hole 51 for locking the locking round bar portion 43 of the connecting body 4 is provided. Each is formed.

The locking hole 51 is a through hole, and when the lid 2 is closed, it is a long hole that is long in the vertical direction, and the inner peripheral surface 511 at the upper end portion and the inner peripheral surface 512 at the lower end portion are rounded and have a rounded shape. The rounded shape is a rounded shape having a gentler curve (curve with a smaller curvature) than the rounded shape at the lower end. Further, the inner peripheral surface 513 on the inner side of the locking hole 51 in the left-right direction has a gentle rounded shape (see FIG. 7). By forming the locking hole 51 in such a shape, the left and right opening operation becomes smooth. The inner peripheral surface 514 on the outer side of the locking hole 51 in the left-right direction may be a straight line. That is, the shape of the inner peripheral surface 514 on the outer side in the left-right direction of the locking hole 51 includes a straight line in this example. The outer inner peripheral surface 514 of the locking hole 51 in the left-right direction is not affected by the upward movement of the locking round bar portion 43 of the locking coupling 4, and does not need to be curved, but the lid 2 is provided. At the time of closing start, the locking round bar portion 43 quickly hits, so that the closing start of the lid 2 is accelerated. In addition, it is possible to prevent the connecting body 4 from rampaging back and forth. Further, locking convex portions 22 and 22 are attached to the front and rear side plates 27 and 27 constituting the lid 2 and in the vicinity of the outer end portions in the lateral direction (left and right direction). The locking protrusions 22 and 22 are small cylindrical protrusions in this example, and are rotatably fitted with the locking recesses 14 and 14 of the upper front and rear upright portions 12a and 12b.

The connecting body 4 connects the pedal portion 3 and the lid 2. By stepping on the pedal portion 3, the connecting body 4 is lifted upward, the lid 2 is opened on both sides, and the pedal portion 3 is released from being depressed. , The connecting body 4 is lowered downward, and the lid 2 is closed. That is, the connecting body 4 has a substantially upright vertical portion 41 whose lower end is rotatably connected to the rear end 33 of the pedal portion 3, and a locking round bar portion 43 extending in the front direction of the dust storage container 1. In this example, a vertically long U-shaped vertical portion 41 composed of two vertical round bar portions 411 and 411 and a horizontal round bar portion 412 connecting the lower ends of the vertical round bar portions 411 and 411. It has a horizontal round bar portion 412 connected to the upper end of the vertical portion 41, and locking round bar portions 43, 43 that bend from both ends of the horizontal round bar portion 412 and extend forward. That is, the connecting body 4 is composed of rods.

The pedal portion 3 is a substantially plate-shaped body, and is rotatably attached under the dust storage container 1 in a seesaw shape. The pedal portion 3 includes a pressure receiving portion 31 extending forward from the container main body 11, which is a portion visible at the time of use, a pedal portion main body 32 rotatably supported by a seesaw at the lower portion of the container main body 11, and a pedal. It has a pedal portion locking portion 33 that rotatably engages with the connecting body 4 at the rear end of the portion main body 32. The pedal portion locking portion 33 rotatably engages with the horizontal round bar portion 412 of the connecting body 4, and in this example, it is a concave portion having a semicircular cross section. The opening forming the semicircle of the pedal portion locking portion 33 faces the front. A damper hole 35, which is a bottomed vertical hole, is formed in the front portion of the pedal portion main body portion 32. A damper 9 is installed in the damper hole 35 to alleviate a sudden return when the pedal portion 3 is depressed. Further, on the front side of the center of the pedal portion 3 in the longitudinal direction, a shaft protrusion 34 rotatably attached to the container body 11 extending outward in the left-right direction is formed. The shaft protrusion 34 rotatably fits into the shaft hole 18 of the container body 11.

Next, how to use the trash can will be described with reference to FIGS. 1, 2, 8, 9 and 12. The trash can 10 in FIG. 1 is in an unused state and is in a standby state. Further, the trash can 10 is installed in one corner of the room where the upper space is narrow. In this standby state, the pedal portion 3 is located at the rear end of the pedal portion main body 32 and the connecting body 4 is located at the lowest point. As a result, the pair of lids 2 are in a lying state (closed state), the abutting tip surfaces (side surfaces) of the left and right side plates face each other with almost no gap, and the double-opening lids 21a and 21b are closed. In this state, it is preferable that the locking round bar portion 43 of the connecting body 4 is close to or slightly in contact with the rounded portion 511 at the upper end of the locking hole 51 of the lid 2. The trash can 10 is excellent in design because the contents (garbage) of the trash container 1 cannot be seen.

Next, when dumping garbage in the trash can 10, first step on the pressure receiving portion 31 of the pedal portion 3. As a result, the rear end of the pedal portion 3 rises upward, and thereby the connecting body 4 also rises upward. The locking position of the locking hole 51 of the locking projection 5 of the lid 2 and the locking round bar portion 43 of the connecting body 4 is the axial support position between the lid 2 and the upper front and rear standing portions 12a and 12b on the dust storage container 1 side. Since it is located on the front side in the front-rear direction, when the connecting body 4 rises upward, the lids 21a and 21b also open in the left-right direction in conjunction with it.

Next, FIGS. 9 to 11 show the locking relationship between the locking holes 51 of the locking projections of the lids 21a and 21b and the locking round bar portion 43 of the connecting body 4 in the process of opening the lids 21a and 21b from the closed state. This will be described with reference to (A) to (H). In the state where the lids 21a and 21b are closed, the locking round bar portion 43 of the connecting body 4 is in contact with the upper end of the locking hole 51 of the lids 21a and 21b. As the locking round bar portion 43 of the connecting body 4 is raised upward, the lids 21a and 21b rotate (open to the left and right) with the axis of the locking convex portion (axis) 22 as the center of rotation. The locking round bar portion 43 of the connecting body 4 moves in the vertical direction, while the locking projection (lid) 5 rotates about the axis of the locking convex portion 22 of the lids 21a and 21b as the center of rotation. Therefore, at the stage where the openings of the lids 21a and 21b are small ((A) to (E) in FIG. 9), the locking round bar portion 43 hits the gentle rounded portion 511 of the upper end portion of the locking hole 51. As the opening of the lids 21a and 21b increases, the locking round bar portion 43 moves inward in the left-right direction (direction in the state where the lid is closed) of the locking hole 51. The inner portion 513 of the locking hole 51 in the left-right direction has a rounded shape, and the locking round bar portion 43 and the locking hole 51 are smoothly locked ((F) to (G) in FIGS. 9). Further, when the opening of the lids 21a and 21b becomes large and the lids 21a and 21b open wide at an angle of bending from the upright position, the locking round bar portion 43 moves from the inner portion 513 in the left-right direction of the locking hole 51 to the lower end portion 512. Move ((G) to (H) in FIG. 9). As described above, when the lids 21a and 21b are opened, the locking round bar portion 43 passes from the rounded shape of the upper end portion 511 of the locking hole 51 to the rounded shape of the inner portion 513 in the left-right direction of the locking hole 51. Then, it moves to the rounded shape of the lower end portion 512 of the locking hole 51.

Next, when closing the lids 21a and 21b, the pedal portion 3 is depressed. In this case, the rear end of the pedal portion 3 is lowered downward due to the weight of the connecting body 4, and the connecting body 4 is also lowered downward. In this case, the locking round bar portion 43 of the connecting body 4 hits the outer portion 514 of the locking hole 51 in the left-right direction (in the state where the lid is closed) from the lower end 512 of the locking hole 51 ((H) in FIG. 11). And (A) of FIG. Since the outer portion 514 of the locking hole 51 in the left-right direction has a linear shape, the closing start of the lids 21a and 21b becomes quick. When the locking round bar portion 43 of the connecting body 4 starts to descend downward, the lids 21a and 21b change from the standing state to the bowing state, so that the lids 21a and 21b are closed at once due to the weight of the lids 21a and 21b. ((B) to (C) in FIG. 12). When the lids 21a and 21b enter the bowing state and are closed at once due to the weight of the lids 21a and 21b, the locking round bar portion 43 moves without being affected by the inner peripheral shape of the locking hole 51.

According to the trash can 10, since the inner peripheral shape of the locking hole 51 on the lid side is a specific shape, the locking hole 51 of the lid 2 and the locking round bar portion 43 can be smoothly locked, and the lids 21a and 21b Opening and closing becomes smooth. Further, the lid 2 is quickly opened by depressing the pedal 3, and the lid 2 is quickly closed by depressing the pedal 3. Further, since one opening / closing lid is divided into two to form a double-opening lid, the height of the upper space can be reduced by half.

According to the present invention, since it can be installed under a desk or a shelf where the upper space is limited, there is more room for selection of the place of use, and the usability is improved. It also responds quickly to pedal depression and depressing.
