DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A trash can according to an embodiment of the present invention will be described below with reference to the drawings. The foldable trash can includes a leg portion A and a bag portion B. These are detailed below.

[Regarding the unfolded state of the leg portion A shown in FIGS. 1 (a) and 2 (a) (b)] Four pairs of legs 1 are sequentially arranged adjacent to each other in an annular shape. In each leg 1 of each set, a first link 2 and a second link 3 intersecting in an X shape are rotatably supported by a support shaft 4 at the intersection. This each leg 1
Are linked as follows:

The center leg 1 and the two adjacent legs 1 that are adjacent to each other on both sides of the center leg 1 will be described among the arbitrary three pairs of legs 1. Between the upper end 2a of the first link 2 of the center leg 1 and the upper end 3a of the second link 3 of the one adjacent leg 1, between the upper end 3a of the second link 3 of the center leg 1 and the other adjacent leg 1 The upper flexible connecting portions 5 are attached to the upper ends 2a of the first links 2, respectively. Further, between the lower end portion 3b of the second link 3 of the central leg 1 and the lower end portion 2b of the first link 2 of the one adjacent leg 1, the lower end portion 2b of the first link 2 of the central leg 1 and the other adjacent leg. Between the lower end 3b of the second link 3 of No. 1 and
The lower flexible connecting portion 6 is attached.

[Details of the upper flexible connecting portion 5 and the lower flexible connecting portion 6] As shown in FIG. 3, the upper flexible connecting portion 5 and the lower flexible connecting portion 6 are It has both elastic arm portions 8 integrally formed in a V shape from plastic and extending from the intersection portion 7 in a bifurcated shape. A shaft portion 9 having a circular cross section is formed on the tip end side of both elastic arm portions 8. The shaft portion 9 is in the cylindrical upper end portions 2a, 3a of the adjacent two links 2, 3 or the cylindrical lower end portions 2b, 3b. It is inserted inside and attached by the support pin 10.

Ends 2a, 3a, 2 of the adjacent links 2, 3
b, 3b extending direction center line P (center line P of the shaft portion 9)
Intersect at an intersection 7 between the elastic arms 8. Both elastic arm portions 8 extend along the center line P to form an acute maximum opening angle θ (60 degrees). Between the shaft portion 9 and the crossing portion 7, arch-shaped doubly-supported elastic beam portions 11 are formed on both elastic arm portions 8 so as to be curved between the center lines P with a radius of curvature R. .

[Bag portion B shown in FIGS. 1 (b), 2 (a) and 2 (b)] The foldable dust bag 12 made of a flexible material has the leg portions A in the unfolded state, and each of the above-mentioned dust bags can be disposed. It is inserted between the flexible connecting portions 5. The mouth peripheral portion 12a at the upper end of the dust bag 12 is supported by each upper flexible connecting portion 5 and opens in a substantially square shape, and the bottom portion 12b at the lower end of the dust bag 12 is at each of the lower sides. It hangs down to the vicinity of the flexible connecting portion 6.

[Changing the width W of the leg A in the unfolded state] In each leg 1 shown in FIGS. 1 (a), 2 (a) and 2 (b), when the intersection angle of both links 2 and 3 is changed In the flexible connecting portions 5 and 6 shown in FIG. 3, the double-supported elastic beam portion 11 is bent to change the opening angle θ between the elastic arm portions 8 and the width W between the upper flexible connecting portions 5 is increased. And the width W between the lower flexible connecting portions 6 is changed together. In this case, the greater the width W of the leg A, the smaller the height of the leg A. Therefore, FIG.
As shown in (b), in the bag portion B supported by the leg portion A, the width W of the mouth peripheral portion 12a of the dust bag 12 is changed.

[Folded state of leg A shown in FIG. 2 (c)] As described above, the crossing angle of both links 2 and 3 is changed, and the width W between the upper flexible connecting portions 5 and When the width W between the lower flexible connecting portions 6 is minimized, the legs A
Is folded. The leg A is tied with a string or the like and stored.

This embodiment has the following features (a) to (b). (A) As described above, when not in use, the legs A can be folded and carried without being bulky, which is very convenient.
Therefore, it is most suitable as a trash can used in camping and the like.

(B) In the leg A, the upper flexible connecting portions 5 and the lower flexible connecting portions 6 are used upside down, and the flexible connecting portions 5 are grounded. At the same time, the mouth peripheral portion 12a of the dust bag 12 can be supported by each of the flexible connecting portions 6. Therefore, any one of the flexible connecting portions 5 and the flexible connecting portions 6 may be used upside down, which is easy to use.

Other than the above embodiment, the following configuration (a) may be adopted. (A) In each of the flexible connecting portions 5 and 6, both elastic arm portions 8
The both-end supported elastic beam portion 11 is linearly extended along the center line P without being curved.

The technical idea (other than claims) that can be understood from each embodiment will be described together with the effects. (A) In claim 1, the upper flexible connecting portion 5 and the lower flexible connecting portion 6 are formed of plastic and have both elastic arm portions 8 extending bifurcated from the intersection portion 7, The elastic arms 8 are connected to the ends 2a, 3a of the adjacent links 2, 3,
It was inserted into 2b and 3b.

Therefore, when the leg A is set to the predetermined width W by changing the intersecting angle of the links 2 and 3, the elastic arms 8 are opened between the flexible connecting portions 5 and 6. It bends according to the angle θ, and due to this elastic return force, both adjacent links 2 and 3 try to open each other. Due to this expanding force, the upper flexible connecting portions 5 are opened to each other and come into contact with the mouth peripheral portion 12a of the soft garbage bag 12, so that the mouth peripheral portion 12a can be tensioned. Further, due to the expanding force, the lower flexible connecting portions 6 also try to open each other, but the flexible connecting portions 6 do not open more than a certain amount due to the friction resistance due to the ground contact, and the leg portions are not opened. A can be maintained at a substantially predetermined width W.

(B) In the above (a), both elastic arm portions 8 are connected to the end portions 2a, 3a, 2b, 3 of the two adjacent links 2, 3.
b has an acute maximum opening angle θ that extends along the extending direction center line P, and has a double-supported elastic beam portion 11 that bends toward the side between the extending direction center lines P at this maximum opening angle θ. doing.

Therefore, the both-end supported elastic beam portion 11 bends so as to increase its radius of curvature R according to the opening angle θ between the both elastic arm portions 8. Therefore, the strength of the double-supported elastic beam portion 11 is increased.

[0022]

The trash box according to the present invention is very convenient because it can be folded and carried without being bulky when not in use.
