Description

The present invention relates to a trash can.

Conventionally, a trash can provided with a plastic trash can main body and a plastic lid (operated by a foot pedal) that opens and closes an upper opening thereof can be opened and closed (see Patent Document 1).

Design Registration No. 1603051 Gazette

The lid gradually opens from the horizontally closed state by stepping on the foot pedal, but if the lid opening angle is (for example) 70 ° or less, the lid can be opened by releasing the foot from the foot pedal. Due to the weight of the lid, it naturally returns to the closed state.

However, the plastic lid is light in weight (lightweight), and even if the foot is taken off the foot pedal, for example, when the temperature exceeds 70 °, especially when the pedal is in a substantially vertical state of about 90 ° when the pedal is finally depressed. There was a problem that the lid did not swing in the closing direction. In addition, since a part of dust and dirt are often attached to the lid, there is a problem that the hand gets dirty when the lid is shaken by applying force to the lid so as to close it. ..

Therefore, the present invention solves such a conventional problem, and even a lightweight lid of a trash can includes a substantially vertical state (final fully open state) of about 90 ° when the foot is taken off the foot pedal. The purpose is to provide a trash can that can be reliably and smoothly restored from the open state to the closed state.

The present invention includes a plastic trash can main body, a pair of left and right lids attached to the upper opening of the trash can main body and capable of opening upwards, and a link means for having a foot pedal and opening the lid. In the trash can, when the foot pedal is stepped on with a foot and in the vicinity of the final step, a part of one component of the link means abuts from below on the bottom wall portion of the trash can body, and the bottom wall portion is elastically deformed. Then, due to the elastic restoring force accompanying the elastic deformation, the pair of lids in the upper Kannon open state are configured to be elastically urged in the closing direction.
Further, the one component is composed of a seesaw band which is arranged at a lower position of the bottom wall portion and swings up and down, and the foot pedal is attached to the front end of the seesaw band, and the seesaw band is further provided. Has a small protruding portion, and the small protruding portion is configured to come into contact with the bottom wall portion from below and elastically deform.

According to the trash can according to the present invention, the lid can be smoothly closed from a substantially vertical state without adding special parts such as a small coil spring and a pinching spring. Therefore, it can be used for a long period of time without worrying about failure due to detachment or loss of the small coil spring or leaf spring. In addition, the bottom wall of a large area is three-dimensionally elastically deformed to exert sufficient elastic restoring force, and a pair of lids that are opened substantially vertically can be reliably closed and a failure occurs. It is difficult to do and has a long life.

Furthermore, each of the pair of left and right lids that open upwards has half its own weight, the length of the arm from the pivot point to the center of gravity is small, and the restoration moment from the open state to the closed state is small, but the bullet Due to the restoring force, it can be closed reliably and smoothly. Alternatively, the pair of left and right lids can be made thinner and lighter. In short, it can be said that it is suitable for an upper double door type lid. Further, it is not necessary to manually close the lid which is opened substantially vertically, which is also preferable in terms of hygiene.

It is a perspective view which shows one Embodiment of this invention, (A) is the whole perspective view in the state which the lid is opened substantially vertically, (B) is the main part enlarged perspective view. It is the whole perspective view with the lid closed. It is explanatory drawing which shows an example of the link means, (A) is a partially broken side surface explanatory view, (B) is an enlarged perspective explanatory view of (b part) of (A). It is a perspective view which showed a different embodiment of a small protrusion. It is a partial cross-sectional side view explaining the action that the bottom wall portion causes elastic deformation. It is a partial cross-sectional front view explaining the operation of a pair of left and right lids that open upward. It is a partial cross-sectional front view which shows the operation which a pair of left and right lids are closed sequentially. It is a top view which shows one Example of a seesaw belt.

Hereinafter, the present invention will be described in detail based on the illustrated embodiment.
In FIGS. 1, 2 and 5, reference numeral 1 denotes a plastic trash can main body, and the trash can main body 1 has an upper opening 2 having a rectangular shape in a plan view. That is, the trash can main body 1 has a front wall portion 11, left and right side wall portions 12, 12, a rear wall portion 13, and a bottom wall portion 14, and the left-right and front-rear dimensions increase slightly as the trash can goes upward from the bottom. As described above, the wall portions 11, 12, and 13 are inclined upward and outward, and the entire trash can main body 1 is a substantially rectangular parallelepiped whose front-rear dimension is longer than the left-right width dimension.

A pair of left and right lids 3 and 4 are pivotally attached to the upper opening 2 having a rectangular shape in a plan view of the trash can body 1 so that the double doors can be opened upward.
Further, the lower edge of the front wall portion 11 is concave to the rear to form a receding wall surface 11A, and a foot pedal P is further arranged on the receding wall surface 11A. That is, the foot pedal P is provided in a protruding shape at a position below the front surface of the trash can main body 1.
Further, the link means 20 is provided so that the lids 3 and 4 can be opened by interlocking and connecting the pedal P and the left and right lids 3 and 4 and stepping on the pedal P with a foot (Fig.). 3, see FIG. 5).

By the way, as shown in FIG. 2 (and FIG. 1), the left and right lids 3 and 4 substantially coincide with the upper surfaces of the lids 3 and 4 except for the inner edge edges 3A and 4A which partially overlap each other in the closed state. Front wall 11
-The height positions of the upper end surfaces 11B and 13B of the rear wall portion 13 are set.

That is, the reinforcing portions 11C and 13C are provided so that the upper end edges of the front wall portion 11 and the rear wall portion 13 are bent into a "gate type" (channel type) or the like, and the upper surfaces of the reinforcing portions 11C and 13C are described above. The upper end surfaces are 11B and 13B.

The pivot shaft 5 of the left lid 3 and the pivot shaft 6 of the right lid 4 shown in FIGS. 6 and 7 are pivotally attached to the small holes of the reinforcing portions 11C and 13C (see FIGS. 1 and 2). , Can be opened by swinging upward like a double door.
Then, when the foot pedal P is stepped on by a person's foot, a part of one component 21 of the link means 20 comes into contact with the bottom wall portion 14 of the trash can body 1 from below in a state near the final step, and the bottom wall. Elastically deform the portion 14 (in the upward direction).

Specifically, as shown in FIGS. 3, 4, and 8, the seesaw band 23 arranged at the lower position (near) of the bottom wall portion 14 is referred to as the one component 21. That is, on the pivot shaft 23A, the seesaw belt 23 has the seesaw belt 23 vertically swingably pivotally attached to the lower portion of the bottom wall portion 14 of the trash can body 1 to form the above-mentioned one component 21. .. A foot pedal P is attached to the front end of the seesaw band 23, and the pedal P can be switched between a horizontal use state and an upright folding state that swings upward, as shown in FIG. The folded pedal P is housed in the recessed portion (left and right band-shaped) formed by the retracting wall surface 11A of the trash can main body 1, and the pedal P in the folded state can be made compact and the obstructive protrusion can be eliminated.

The seesaw band 23 has a small protrusion 24 as shown in FIGS. 4 (A), 3, 5, and 8, and the arrangement position of the small protrusion 24 is centered in the longitudinal direction. It is a position slightly closer to the rear end 23B than the nearby pivot axis 23A. More specifically, the small protrusion 24 projects upward on the center line in the width direction and at a position slightly rearward from the center position where the pivot shaft 23A is located. The small protrusion 24 can be elastically deformed by abutting the bottom wall portion 14 of the trash can body 1 from below.

Further, as shown in FIGS. 8 and 4 (A), the shape of the small protrusion 24 is a left and right single-character small projectile piece 24A and two front and rear triangular reinforcing pieces for preventing the small projectile piece 24A from collapsing. It consists of 24B and 24B. Alternatively, as shown in FIG. 4B, only the left and right single-character small projectile pieces 24A, which increase as the wall thickness goes downward, can be used. Alternatively, the Maruyama shape shown in FIG. 4C is also possible. By the way, it is desirable that the small protrusion 24 is integrally molded with the seesaw band 23 with plastic. That is, this is because it has the effect that problems such as the small protrusion 24 coming off are unlikely to occur. It should be noted that it is also possible to have an upward protruding shape other than the one shown in the figure.

Then, the overall structure and action of the link means 20 will be described below.
In FIGS. 1, 3, 5, 5, 6 and 8, the link means 20 includes a pedal P, a seesaw band 23 having the pedal P at the front end, and a shaft at the rear end of the seesaw band 23. Engage with the elevating interlocking band 30 in which the lower end 30A is pivotally connected to the portion 23C, and the engaging protrusions (dove) 30C and 30D provided on the left and right sides of the upper end 30B of the elevating interlocking band 30 as forward protrusions. As such, it is composed of a ring body 8 or the like projecting from the inner surface of the lids 3 and 4.

A part (small protrusion 24) of the seesaw band 23, which is one component 21 of the link means 20 configured in this way, comes into contact with the large-area bottom wall portion 14 of the trash box body 1 from below. , Elastically deformed (caused three-dimensional three-dimensional elastic deformation), and the elastic restoring force G (see FIG. 5C) accompanying this elastic deformation is engaged with the elevating interlocking band 30 of the link means 20 and protrudes. A pair of lids 3 and 4 in an upward Kannon open state are elastically repelled in the closing directions M ₃ and M ₄ indicated by the dotted arrows in FIG. 6 (C) via the children 30C and 30D and the ring bodies 8 and 8. Encourage. Note that N ₃₀ indicates a downward urging force that the elevating interlocking band 30 acts to close the lids 3 and 4.
Below the bottom wall portion 14 of the trash can main body 1, the seesaw band 23 is integrally provided with hanging wall portions 9 and 9 in order to form a space portion that can swing up and down at a small angle ( (See FIG. 5).

Further, as shown in FIGS. 3 (B) and 6 (C), cantilever-shaped arms 30E and 30E are formed in a protruding shape (to the left and right outward) at the upper end 30B of the elevating interlocking band 30. The engaging protrusions 30C and 30D are integrally attached to the tip of the beam. Further, as is clear from FIG. 1, the ring body 8 into which the engaging protrusions 30C and 30D are inserted and engaged is the inner surface of each of the left and right lids 3 and 4, and is located at the rear and lower corners. , It is integrally formed as a protruding shape.

Next, in the embodiment of the present invention, as shown in FIGS. 6 and 7, the left lid 3 and the right lid 4 have a difference in the left and right opening angles, particularly under a small opening state close to the closed state. Giving. In other words, it is provided with a mechanism that does not open and close symmetrically and is slightly differential.

As shown in FIGS. 1, 2 and 6 and 7, an upper opening-shaped recess 31 is provided in the inner edge 3A of one lid 3, and the inner edge 4A of the other lid 4 is provided. Is provided with a downward opening recess 32. Then, the recesses 31 and 32 overlap each other so as to mesh with each other with the lid closed. Moreover, an inverted cup-shaped or gate-shaped cross-sectional ridge 33 is formed on the inner edge 4A of the other lid 4 so as to project upward from the plane of the entire lid, and the recess 32 is formed. It can be said that it is formed by the protruding portion 33.

In FIG. 7, as shown in (A), (B), and (C), it is shown that the intermediate open state is gradually closed, and finally the fully closed state is reached, but the left lid 3 comes first. It swings downward so as to close to, and swings downward so that the right lid 4 chases afterwards, thereby avoiding the two lids 3 and 4 colliding with each other. As can be seen from FIGS. 7 (A), (B) and (C), in order to generate such a differential, the right locking protrusion (dowel) 30D is more than the left locking protrusion (dowel) 30C. Set the vertical position of.
By providing a difference between the top and bottom of the left and right locking protrusions 30C and 30D in this way, the inner end edges 3A and 4A of both lids 3 and 4 do not collide, and smooth opening and closing operation ─── especially closing operation ─ ── is realized.

In order to cause the above-mentioned differential, the shapes of the ring body 8 of the left lid 3 and the ring body 8 of the right lid 4 are different, or the left and right ring bodies 8 and 8 are separated from the pivot axes 5 and 6. It is also preferable to give a magnitude difference to the distance (not shown).
The shapes of the left and right lids 3 and 4 may be other than those shown in the drawings. Further, the left and right lids 3 and 4 can be opened and closed at the same time without being differentiated, so that the inner edge edges 3A and 4A do not overlap (in the closed state).

As described in detail above, the present invention includes a plastic trash can main body 1, a pair of left and right lids 3 and 4 attached to the upper opening 2 of the trash can main body 1 and capable of opening upwards, and a foot pedal P. In a trash can provided with the link means 20 for opening the lids 3 and 4, a part of one component 21 of the link means 20 is in a state near the final stepping by stepping on the foot pedal P with a foot. The bottom wall portion 14 of the trash can body 1 is abutted from below to elastically deform the bottom wall portion 14, and the elastic restoring force G accompanying the elastic deformation causes the pair of lids 3 and 4 to be opened upward. Close since it is configured to direction M _3, M urged ₄ resiliently separately, requires without failure or leaving easily small coil spring and sandwiched spring, be easily trash generated not long life failures can be manufactured It becomes.

Further, even the lightweight plastic lids 3 and 4 can be smoothly closed from a substantially vertical state.
In particular, since the bottom wall portion 14 having a large area is elastically deformed three-dimensionally, it is possible to exert a sufficiently large elastic restoring force G and reliably and smoothly close the lids 3 and 4 which are opened substantially vertically. It can be made, is less likely to break down, and has excellent durability.
Furthermore, since the restoration moment in the closing direction of the pair of left and right lids 3 and 4 that open upward is as small as about half (compared to a single lid), it is easy from around 90 ° (approximately vertical). There was a risk of stopping without trying to close it, but in the present invention, it is particularly effective for such an upward double door type trash can. In addition, it is possible to prevent human hands from getting dirty.

Further, the one component 21 is composed of a seesaw band 23 which is arranged below the bottom wall portion 14 and swings up and down, and the foot pedal P is attached to the front end of the seesaw band 23. The seesaw band 23 has a small protrusion 24, and the small protrusion 24 is configured to abut from below on the bottom wall portion 14 to elastically deform the seesaw band 23. It abuts most smoothly on the part 14, and the elastic restoring force G due to the elastic deformation of the bottom wall part 14 can be utilized with high efficiency. Structurally, only the small protrusion 24 needs to be added, and manufacturing is easy. Moreover, it can be said that there is almost no cost increase.
