Description

Underfloor trash can structure

[0001] This invention relates to an underfloor trash can structure that stores a trash can under the floor.

[0002] Various types of under-floor trash can structures have been proposed.

[0003] For example, Patent Document 1 discloses an underfloor storage trash can in which a bucket with raised edges for setting plastic bags is set on a fixed frame under a floor hatch cover similar to that of an underfloor storage.

[0004] Patent document 2 also discloses an underfloor dust box that is composed of a lid that can be attached and detached to an opening in the floor surface, a dust box body that is positioned corresponding to the opening in the underfloor space, and a frame that can be attached and detached to the upper edge of the dust box body and that holds a garbage bag that is set from the inside of the dust box body to the upper edge.

[0005] Furthermore, Patent Document 3 discloses an underfloor trash sorting bin in which a trash inlet / outlet opening is provided on the kitchen floor, and a rotating trash sorting bin is installed under the kitchen floor, with multiple sorting bins supported by a rotating support around their center of rotation, so that each sorting bin can be positioned at the trash inlet / outlet opening by rotating it.

[0007] However, in both cases, the upper edge of the trash can is under the floor, making it difficult to remove from under the floor.

[0008] The present invention has been made in light of the above circumstances, and its purpose is to provide an under-floor trash can structure that allows the trash can to be easily removed from under the floor.

[0009] In order to solve the above problems, the underfloor trash can structure of the present invention is characterized by comprising an underfloor inspection hatch provided in the floor, a trash can that is detachably attached to the underfloor inspection hatch, an elastic member that biases the trash can so as to lift it out of the underfloor inspection hatch, and a floor hatch that allows the trash can to be attached to the underfloor inspection hatch against the biasing force of the elastic member.

[0010] According to the underfloor trash can structure of the present invention, the trash can can be easily removed from under the floor.

[0012] Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

[0013] In FIG. 1, reference numeral 1 denotes an under-floor trash can structure according to one embodiment of the present invention.

[0014] In this underfloor trash can structure 1, a trash can 5 is removably attached to an underfloor inspection hatch 4 having an inspection hatch 3, for example, of a square shape, provided in a floor 2.

[0015] As shown in FIGS. 2 and 3, the trash can 5 includes a first trash can 6 for storing, for example, burnable trash, and a second trash can 7 for storing, for example, non-burnable trash.

[0016] These first trash can 6 and second trash can 7 are formed, for example, in a rectangular shape, and the rectangular first trash inlet 8 and second trash inlet 9 formed at the top are sized to be arranged side by side in the underfloor inspection hatch 4.

[0017] Each of the first trash can 6 and the second trash can 7 has a flange 10 extending outward from the outer periphery of the upper portion.

[0018] As shown in Figure 4, a floor hatch 11 that covers the inspection hatch 3 is removably attached to the underfloor inspection hatch 4, and this floor hatch 11 has a first lid body 12 that covers the first trash can 6 in an openable and closable manner, a second lid body 13 that covers the second trash can 7 in an openable and closable manner, and a hinge portion 14 that rotatably supports the first lid body 12 and the second lid body 13.

[0019] The hinge portion 14 includes a hinge support 15 provided between the first cover body 12 and the second cover body 13, a first hinge 16 that rotatably supports the first cover body 12 on the hinge support body 15, and a second hinge 17 that rotatably supports the second cover body 13 on the hinge support body 15.

[0020] The hinge portion 14 is positioned above the adjacent flange portions 10 of the first trash can 6 and the second trash can 7 .

[0021] The first cover 12 and the second cover 13 are provided with a first handle 18 and a second handle 19, respectively, on the side opposite to the hinge portion 14.

[0022] The floor 2 in which the inspection hatch 3 is formed is supported by floor joists 21.

[0023] A square annular support frame (receiving part) 22 is attached to this joist 21 by a first mounting member 23 such as a screw so that it is positioned below the inner edge of the inspection hatch 3, thereby preventing the flange part 10 from moving downward.

[0024] In addition, as shown in Figure 5, on the inner periphery of the inspection hatch 3 of the underfloor inspection hatch section 4, a square annular outer frame 24 is attached to the joist 21 by a second mounting member 25 such as a screw, and has an outer periphery regulating section 26 that receives the outer periphery of the floor hatch 11 to regulate its movement, and a receiving section 27 that receives the outer periphery underside of the floor hatch 11.

[0025] Furthermore, a foundation portion 31 provided below the floor 2 is provided with a first spring member (elastic member) 32 that biases the first trash can 6 so as to lift it up from the underfloor inspection hatch portion 4, and a second spring member (elastic member) 33 that biases the second trash can 7 so as to lift it up from the underfloor inspection hatch portion 4.

[0026] When the floor hatch 11 is attached to the underfloor inspection hatch section 4, the first trash can 6 and the second trash can 7 that can be lifted are pushed down against the biasing force of the first spring member 32 and the second spring member 33, and are attached to the underfloor inspection hatch section 4.

[0027] According to the above configuration, as shown in Figures 6 and 7, when the floor hatch 11 is lifted, the first trash can 6 and the second trash can 7 are lifted by the biasing forces of the first spring member 32 and the second spring member 33, so that the trash can 5 can be easily removed from under the floor 2.

[0028] Furthermore, since the hinge portion 14 is positioned on the adjacent flange portions 10 of the first trash can 6 and the second trash can 7, even when the first cover body 12 and the second cover body 13 are opened, the first trash can 6 and the second trash can 7 will not be lifted by the biasing force of the first spring member 32 and the second spring member 33.

[0029] The disclosure of the present invention described above can be summarized at least as follows.

[0030] In other words, the underfloor trash can structure of the present invention is characterized by comprising an underfloor inspection hatch provided in the floor, a trash can that is detachably attached to the underfloor inspection hatch, an elastic member that biases the trash can so as to lift it out of the underfloor inspection hatch, and a floor hatch that allows the trash can to be attached to the underfloor inspection hatch against the biasing force of the elastic member.

[0031] The present invention may include at least the following embodiments, which may be adopted separately or in combination with each other.

[0032] (1) The trash can has a flange portion that extends outward, and the underfloor inspection hatch portion has a receiving portion that prevents the flange portion from moving downward.

[0033] (2) The trash cans include a first trash can and a second trash can that are attached in parallel to the underfloor inspection hatch, and the floor hatch includes a first lid body that covers the first trash can in an openable and closable manner, a second lid body that covers the second trash can in an openable and closable manner, and a hinge portion that rotatably supports the first lid body and the second lid body.
