Description

[Technical Field]

[0001] The present invention relates to a trash can that has a single trash inlet that can be releasably divided into two sections, and by setting trash bags in each section, it is possible to selectively give the trash can a separate collection function. [Background technology]

[0002] In recent years, in order to reduce weight and the use of materials, many trash cans have been sold commercially that can form a trash collection area by holding trash bags in frame members. In particular, as the recycling of trash resources is promoted, separate collection of trash is essential.

[0003] In addition, because the types of waste that need to be separated are so diverse, it is common for households to have multiple trash cans. In such cases, they are often set up with the same type and capacity.

[0004] However, the amount of each type of garbage collected varies from household to household, and some types of garbage are collected in relatively small amounts per collection cycle, so allocating the same number of garbage bins to all types would be inefficient and would occupy too much space, making it impractical.

[0005] Therefore, many trash cans have been developed that can increase the number of trash sorts by simply dividing the trash container and adding a separate collection function, even if the overall capacity is the same. The mechanism for dividing the trash container is to divide the opening of the trash container into multiple small openings, and each small opening holds a trash bag, which then becomes a trash sorting container. In this case, a dedicated dividing member is installed at the opening of the trash can.

[0006] For example, Patent Document 1 discloses a trash can with separate disposal capabilities that allows for the separate disposal of multiple types of trash by installing a separate attachment at the top of the trash can, which has multiple divided frames integrally molded into it to engage the upper edges of multiple trash bags. [Prior art documents] [Patent documents]

[0007] [Patent Document 1] Japanese Patent Application Laid-Open No. 2006-327751 Summary of the Invention [Problem to be solved by the invention]

[0008] As described above, in a configuration in which the opening is simply divided by simply placing a dividing member at the opening of the trash can, and multiple trash storage sections are formed by placing trash bags in each section, by removing the dividing member, the trash can can be returned to a single large opening, so it can be switched between sorting and other uses as appropriate.

[0009] However, because the dedicated dividing members are made by molding multiple frame members into a predetermined size and shape, the manufacturing process of the trash can requires a relatively time-consuming molding process for the dividing members, significantly increasing the amount of material and cost. Moreover, the dividing members require separate space to store them when not in use, making them difficult to handle.

[0010] In view of the above problems, the object of the present invention is to provide a trash can that is easily given a separate collection function by being equipped with a partition member that serves as a simple partition for the opening of the trash storage section, thereby reducing manufacturing costs and material usage compared to conventional methods and reducing storage space when not in use. [Means for solving the problem]

[0011] In order to achieve the above object, as shown in Figures 1 to 9, the trash can according to the invention of claim 1 comprises a substantially rectangular bottom plate member placed on a trash can installation surface, four support posts of the same length removably erected near the four corners of the bottom plate member, a substantially rectangular upper frame member removably supported on the upper ends of the four support posts, a fixed frame member removably fitted from the outside to the upper surface and outer circumferential surface of the upper frame member to sandwich the upper end of the opening of a trash bag, and left and right opening / closing doors of a double-door type that are attached to the fixed frame member and can be opened and closed to close the opening of the fixed frame member, and are disposed in an inner space between the four support posts and are connected to the upper frame member and the fixed frame member. This is a disassemblable trash can in which the trash storage section is formed by trash bags whose opening upper ends are sandwiched between the upper frame member and a fixed frame member, and the upper frame member further comprises two rod-shaped partition members that are parallel to each other at opposing positions and detachably span across the center of the opening, dividing the opening of the upper frame member into two small openings, and bag fixing devices that are detachably hooked onto the two rod-shaped partition members and sandwich the opening upper ends of each trash bag hooked onto the edges of the small openings between the rod-shaped partition members, and the left and right opening doors are attached to the fixed frame member so that they can rotate independently of each other.

[0012] According to the trash can of claim 1 of the present invention, four support posts are erected from a bottom plate member, and an upper frame member is supported on the upper ends of these four support posts to form a main frame of the trash can. A trash bag is placed between the four support posts on this main frame, and the open end of the trash bag is folded back from the inside to the outside and hooked onto the upper frame member. Then, a fixed frame member is fitted onto the upper frame member from the outside, thereby securing the trash bag in place. This completes a trash can with a lid and a door that opens from the left and right, with the openings of the fixed frame member and the upper frame member forming a single trash inlet and the interior of the trash bag forming a single trash storage space.

[0013] Then, with the fixed frame member removed from the upper frame member, leaving only the main frame, two rod-shaped partition members are hung across the upper frame member so as to cross the center of its opening, thereby dividing the opening of the upper frame member into two small openings.

[0014] Therefore, two garbage bags are placed inside the four support posts, and the open ends of each garbage bag are folded back from the inside to the outside and hooked onto the edges of each small opening, and the open ends of the garbage bags are clamped and fixed from above each rod-shaped partition member with bag fixing devices, and then the fixed frame member is fitted into the upper frame member from the outside, thereby forming a sorting garbage bin with two garbage inlets and two garbage storage spaces below the opening of the fixed frame member.

[0015] In addition, when this trash sorting system is used, the two trash inlets can be opened and closed separately by left and right doors that rotate independently of each other, preventing different types of trash from getting mixed in.

[0016] From the above-mentioned structure, the trash can according to the present invention is essentially made up of only two rod-shaped partition members that are hung across the upper frame member and divide the opening into two, and is endowed with a separate collection function without incurring a significant increase in material and manufacturing costs or storage space when not in use compared to conventional trash cans.Users can choose between a single-inlet trash can with a relatively large trash storage space and a double-inlet trash can that can separate and collect two types of trash, as needed, and can easily be changed to use either one.

[0017] Furthermore, the means for bridging the two rod-shaped partition members across the center of the opening of the upper frame member in this invention is not particularly limited as long as it is a mechanism that allows the two rod-shaped partition members to be easily attached and removed, but it is preferable to have a simpler design that does not require special parts or the like for this purpose.

[0018] For example, two opposing grooves with inner diameters roughly matching the outer diameters of the ends of each rod-shaped partition member may be provided on the upper surface of the upper frame member. In this case, the rod-shaped partition members can be bridged over the center of the opening simply by inserting their ends into the grooves from above, and the rod-shaped partition members can be easily removed by simply lifting them up.

[0019] The trash can according to the invention described in claim 2 is characterized in that, for example, as shown in FIG. 1, the four support poles are each extendable and adjustable in length.

[0020] According to the trash can of claim 2 of the present invention, the four support posts that essentially determine the height of the trash can are adjustable in length, so the user can appropriately set the height of all support posts according to the desired trash can installation space. This makes it possible to install the trash can in an inconspicuous location, for example, and utilize wasted indoor space.

[0021] The telescopic function of each support column is preferably such that the length can be adjusted quickly and easily, and no special configuration is required; an existing mechanism can be used. For example, a simple telescopic mechanism can be configured for each support column using an outer pipe with multiple screw holes drilled at predetermined intervals, an inner pipe with a smaller diameter that overlaps the outer pipe, and screws that are fastened to the screw holes.

[0022] In this case, the lower region of the interior pipe can be slid relative to the exterior pipe, and the interior pipe can be fixed at any height by tightening the screw member against the outer surface of the interior pipe via a predetermined screw hole. With this telescopic mechanism, the interior pipe can be moved again relative to the exterior pipe simply by loosening the screw member, and the height of the support can be changed and the screw member can be tightened again to fix it at the changed height.

[0023] The trash can of the invention described in claim 3 is characterized in that, as shown in Figures 1, 2, 3, 5 and 8, the bottom plate member has lower support hole portions formed near its four corners, into which the lower ends of the four support pillars are removably inserted, and the upper frame member has upper support hole portions formed at positions opposite the lower support hole portions near the four corners on its back surface, into which the upper ends of the four support pillars are removably inserted.

[0024] According to the trash can of claim 3 of the present invention, the lower and upper ends of the four pillars are removably inserted into the lower support hole portion of the bottom plate member and the upper support hole portion of the upper frame member opposite these, thereby assembling the bottom plate member and the upper frame member via the four pillars to form the main frame of the trash can.

[0025] Therefore, when in use, the main body frame of the trash can can be assembled by first inserting each support pole into the corresponding upper and lower support hole parts, and when not in use, the main body frame can be easily disassembled by simply removing each support pole from the corresponding upper and lower support hole parts.

[0026] The trash can according to the invention described in claim 4 is characterized in that, for example, as shown in Figure 10, the bottom plate member has a recessed support pillar storage space on the inside, and the four support pillars can be stored in the support pillar storage space of the bottom plate member when they are detached from the bottom plate member and the upper frame member and in their shortest, most shortened state.

[0027] According to the trash can described in claim 4 of the present invention, after the trash can is disassembled, the four support pillars can be stored in the support pillar storage space of the bottom plate member in the shortest and most shortened state, and this storage state allows all components to be packed compactly, so that only a small space is required for storage.

[0028] Furthermore, since the upper frame member can be made to have approximately the same external shape as the bottom plate member and the fixed frame member can be made only slightly larger than the upper frame member, the upper frame member and the fixed frame member with the four support pillars removed can be stored in the support pillar storage space by stacking them on top of the bottom plate member with the four support pillars housed in it.

[0029] The trash can according to the invention of claim 5 is characterized in that, as shown in Figures 2 to 5, the outer peripheral shape of the fixed frame member and the inner peripheral shape of the opening and the outer peripheral shape of the bottom plate member are approximately rectangular, and the left and right opening doors have a shape divided in two along the short side of the opening so that their door edges close at the center of the longitudinal direction of the opening of the fixed frame member, and are attached to the left and right inner sides of the longitudinal direction of the opening of the fixed frame member so that they can rotate around the longitudinal direction as the rotation center.

[0030] When the trash can is shaped like a box with a roughly rectangular cross section, which is the most common shape, the outer peripheral shape and inner peripheral shape of the opening of the fixed frame member and the outer peripheral shape of the bottom plate member are roughly rectangular, so using the longitudinal direction of the mounting parts of the left and right opening doors as the center of rotation minimizes the amount of upper space required for opening and closing rotation.

[0031] According to the trash can of claim 5 of the present invention, the rectangular door that closes the substantially rectangular opening of the fixed frame member is attached to the inside surface of the opening at both left and right longitudinal edges of the door. Therefore, the door pivots open and close around the longitudinal direction, and the pivot radius is the same as the width of the door. Therefore, the space above the door that needs to be secured for the door to pivot open and close is smaller than when the width of the door is the pivot center. This allows for greater flexibility in selecting the storage space for the trash can.

[0032] The left and right opening / closing doors in the above configuration are opened and closed independently of each other when the trash can is used as a sorting type, but it is desirable to provide a means of grip on the surface of each door to make opening and closing easier.

[0033] For example, it is possible to provide a grip such as a handle, lever, or ball grip, but since protruding parts into the trash can would increase the space it occupies as a trash can, a concave handle is preferable.

[0034] It is also preferable to provide a means for keeping the door closed so that the trash can will not fall over and spill out if the door opens. For example, a commercially available push latch is easy to use. This type of latch is constructed by attaching a main body with a roughly V-shaped locking portion, which constitutes the push latch, to a fixed frame member, and installing an engagement protrusion on the back side of the door.

[0035] The door is designed to be closed by a spring mechanism inside the main body, which engages the engaging protrusion with the locking part when the door is pushed, and then disengages the engaging protrusion from the locking part when the door is pushed again, allowing the door to be opened.Such a push latch can be provided between the rear surface of the left and right opening doors and the fixed frame member. [Effects of the Invention]

[0036] As explained above, the trash can of the present invention can be disassembled and assembled as needed, and the opening of the upper frame member is divided into two small openings by two rod-shaped partition members that are detachably hung across the center of the opening of the upper frame member, and the left and right doors that close the opening in a folding style can be opened and closed independently, thereby providing the effect of giving the trash can a separate collection function without incurring an increase in materials, cost, or storage space compared to conventional trash cans.

[0037] Therefore, the user can freely select and easily change between a single-garbage-inlet type box having one garbage storage space with one garbage bag set in one opening and a two-garbage-inlet type sorting garbage box having two garbage storage spaces with two garbage bags set in two small partitioned openings, depending on his or her needs.

DETAILED DESCRIPTION OF THE INVENTION

[0039] An embodiment of the present invention will be described below with reference to the drawings.

[0040] <Embodiment> 1 to 10 show one embodiment of a trash can according to the present invention. The trash can 1 in this embodiment is adjustable in height, can be disassembled and reassembled, and can be freely changed between a trash can configuration with one trash inlet and a trash can configuration with two trash inlets for separate collection.

[0041] As shown in FIG. 1, the trash can 1 of this embodiment is configured such that the main body framework 4 of the trash can 1 is composed of a substantially rectangular bottom plate member 10 that is placed on the trash can installation surface, four support posts (20a, 20b, 20c, 20d) that are erected by having their lower ends removably inserted into lower support holes (11a, 11b, 11c, 11d) formed near each of the four corners of the bottom plate member 10, and a substantially rectangular upper frame member 30 that is supported on these four support posts (20a, 20b, 20c, 20d).

[0042] In addition, the upper frame member 30 is supported by each of the four pillars (20a, 20b, 20c, 20d) by removably inserting the upper ends of the pillars into upper support holes (32a, 32b, 32c, 32d) formed on the back surface near each of the four corners.

[0043] In this embodiment, the bottom plate member 10 and the upper frame member 30 are made of synthetic resin, and when they are molded, the mold is used to simultaneously and integrally form the respective lower support hole portions (11a, 11b, 11c, 11d) and upper support hole portions (32a, 32b, 32c, 32d) in the bottom plate member 10 and the upper frame member 30.

[0044] As shown in Figure 2, a fixed frame member 40 is fitted into the upper frame member 30 supported by the upper ends of the four support pillars (20a, 20b, 20c, 20d) so as to sandwich the upper open end of the garbage bag 2 and be detachably attached from the outside, thereby completing the garbage can 1 in which a garbage storage space is formed by the main body of the garbage bag 2 arranged between the four support pillars (20a, 20b, 20c, 20d).

[0045] The fixed frame member 40 has an inverted L-shaped cross section that fits from the outside onto the upper surface and outer peripheral surface of the upper frame member 30. In this embodiment, the outer shapes of the bottom plate member 10, the upper frame member 30, and the fixed frame member 40 are generally rectangular, and the opening 31 of the upper frame member 30 and the opening 41 of the fixed frame member 40 are also generally rectangular.

[0046] Left and right doors (42a, 42b) of double door type are attached to the inner longitudinal side surface of the fixed frame member 40 via hinges H so as to openably and closably close the openings (31, 41).

[0047] In this embodiment, the fixed frame member 40 and the left and right opening doors (42a, 42b) are also made of synthetic resin, which allows the entire trash can to be lightweight. Note that the fixed frame member 40 and the left and right opening doors (42a, 42b) can be molded separately and then connected via hinges H to easily form a frame member with a lid.

[0048] Furthermore, the left and right opening doors (42a, 42b) in this embodiment are shaped to bisect the opening 41 in the short direction so that the door edges close at the longitudinal center of the opening 41. As a result, the left and right opening doors (42a, 42b) rotate to open and close around the longitudinal direction of their mounting portions, and the rotation radius is the short dimension of the doors (42a, 42b), and the space required for opening and closing rotation can be kept small.

[0049] Furthermore, each of the four support pillars (20a, 20b, 20c, 20d) is constructed so that it is extendable and adjustable in length, with an outer pipe P1 and an inner pipe P2 of smaller diameter that overlaps it on the inside, and by changing the length, the height, i.e., depth, of the trash can 1 can be changed.

[0050] Specifically, multiple screw holes Ph are drilled at predetermined intervals in the outer pipe P1, and the lower region of the inner pipe P2 is slid relative to each outer pipe P1, and at the desired height, the screw member 21 is screwed into one or more of the screw holes Ph in the outer pipe P1 that overlap the outer surface of the inner pipe P2 and tightened.

[0051] As a result, by fastening the screws to the outer surface of the interior pipe P2, the interior pipe P2 can be fixed in position relative to the exterior pipe P1, and the height of the support columns (20a, 20b, 20c, 20d) can be fixed.

[0052] Therefore, the inner diameter of the lower support hole portion (11a, 11b, 11c, 11d) of the bottom plate member 10 into which the lower end portion is inserted is set to a dimension that fits into the outer diameter of the outer pipe P1, and the inner diameter of the upper support hole portion (32a, 32b, 32c, 32d) of the upper frame member 30 into which the upper end portion is inserted is set to a dimension that fits into the outer diameter of the upper pipe P2.

[0053] In the above configuration, the main body frame 4 of the trash can 1 can be easily assembled by simply inserting the lower ends of the four support pillars (20a, 20b, 20c, 20d), which have been adjusted to the same desired length, into the lower support hole portions (11a, 11b, 11c, 11d) of the bottom plate member 10 to erect them, and then inserting the upper ends of these four support pillars (20a, 20b, 20c, 20d) into the corresponding upper support hole portions (32a, 32b, 32c, 32d) to support the upper frame member 40.

[0054] Then, as shown in Figure 2, the first garbage bag 2 is placed inside the four support pillars (20a, 20b, 20c, 20d), and the open end of the garbage bag 2 is hooked onto the upper frame member 30 by folding it from the inside to the outside, and then the fixed frame member 40 is fitted onto the outside of the upper frame member 30.

[0055] As a result, the open end of the garbage bag 2 is sandwiched and fixed between the upper frame member 30 and the fixed frame member 40, and a single garbage opening type garbage can 1 is completed, which has one garbage storage space consisting of one garbage bag 2, as shown in Figures 3 and 4.

[0056] As shown in FIG. 1, the trash can 1 of this embodiment is provided with two rod-shaped partition members (50a, 50b) for converting the trash can 1 into a separate type capable of separately collecting two types of trash, and a bag fixing device 60 that is removably hooked onto each of the rod-shaped partition members (50a, 50b) for sandwiching the open end of a second trash bag (3a, 3b) described later between the rod-shaped partition members (50a, 50b).

[0057] Specifically, as shown in Figure 6, two rod-shaped partition members (50a, 50b) are detachably bridged parallel to each other across the center of the opening 31 of the upper frame member 30, thereby dividing the opening 31 into two small openings (31a, 31b) in the short direction.

[0058] Furthermore, two pairs of grooves (33a, 33b) are formed in each short region of the upper frame member 30, opening at two opposing central locations on the upper surface, into which both ends of each rod-shaped partition member (50a, 50b) are inserted, respectively.

[0059] Therefore, after assembling the main frame 4 of the trash can 1 described above, and before setting the trash bags, the two rod-shaped partition members (50a, 50b) can be installed across the center of the opening 31 of the upper frame member 30 simply by inserting both ends of each into two pairs of grooves (33a, 33b) formed in the opposing short areas of the upper frame member 30.

[0060] As a result, the opening ends of second garbage bags (3a, 3b), which are smaller than the first garbage bag 2, are hooked onto the two small openings (31a, 31b) formed by folding them from the inside to the outside as shown in Figure 6(c), and then bag fixing devices 60 are hooked from above the two rod-shaped partition members (50a, 50b) to clamp and fix the opening ends of the second garbage bags (3a, 3b).

[0061] As the bag fixing device 60, for example, a clip-shaped device that is hooked onto each of the two rod-shaped partition members (50a, 50b) by elastic deformation is preferable because it is easy to attach and detach.

[0062] 7, when the fixed frame member 40 is fitted from the outside of the upper frame member 30, two trash inlets consisting of two small openings (31a, 31b) are present below the left and right opening doors (42a, 42b). Two trash storage spaces consisting of second trash bags (3a, 3b) respectively communicating with these two trash inlets are provided, completing the assembly of the trash can 1 for sorting.

[0063] Furthermore, when using this trash can 1 as a sorting type, the second trash bags (3a, 3b) can be removed by removing the fixing frame member 40 from the upper frame member 30 and also removing the bag fixing device 60, as shown in Figure 5.

[0064] Furthermore, as shown in Figure 2, once the two rod-shaped partition members (50a, 50b) are removed, a new first garbage bag 2 can be set and the fixed frame member 40 can be fitted into the upper frame member 30, and the garbage can 1 can be easily returned to a single garbage opening type with a single garbage storage space.

[0065] The trash can 1 in this embodiment having the above configuration can be easily disassembled by removing the fixed frame member 40 from the upper frame member 30, pulling out the upper ends of the four support pillars (20a, 20b, 20c, 20d) from the upper support hole portions (32a, 32b, 32c, 32d) of the upper frame member 30, and pulling out the lower ends from the lower support hole portions (11a, 11b, 11c, 11d) of the bottom plate member 10.

[0066] In this embodiment, a recessed pillar storage space 12 is provided in the bottom plate portion 10, and the lengths of the outer pipe P1 and the inner pipe P2 of the four extendable pillars (20a, 20b, 20c, 20d) can be preset so that they fit within the longitudinal inner dimensions of the pillar storage space 12 when in their shortest, most contracted state.

[0067] In this case, as shown in FIG. 10(a), after disassembling the basic frame 4, the four support columns (20a, 20b, 20c, 20d) that have been extended or retracted to their shortest lengths can be accommodated in the support column accommodating space 12 of the bottom plate portion 10.

[0068] In this case, if the upper frame member 30 has an outer shape that is roughly the same as that of the bottom plate member 10, the upper frame member 30 can be placed on top of the bottom plate member 10 while the two rod-shaped partition members (50a, 50b) are bridged and engaged together with the bag fixing device 60. Furthermore, the fixing frame member 40, which has an outer shape that is slightly larger than the bottom plate member 10 and the upper frame member 30, can also be placed on top of them, so that the entire unit can be made compact as shown in Figure 10(b), and can be stored in a narrow space such as a crevices when not in use.

[0069] In addition, the trash can 1 of this embodiment is equipped with push latches (La, Lb) as door stoppers that releasably engage with the fixed frame member 40 and predetermined positions on the back surfaces of the left and right opening doors (42a, 42b).

[0070] Here, the main body constituting the push latches (La, Lb) is embedded in the fixed frame member 40, and the engaging projections are provided on the rear surfaces of the left and right opening doors (42a, 42b). These push latches (La, Lb) eliminate the risk of the left and right opening doors (42a, 42b) opening by themselves and causing trash to spill out, even if the trash can 1 falls over while in use. [Industrial Applicability]

[0071] In the above embodiment, the trash can according to the present invention is configured so that the trash can is completed by clamping a flexible trash bag at the upper end of its opening, i.e., functions as a trash bag holding frame. However, the trash can can also be applied as a hard box-type trash can in which, instead of a trash bag, for example, a plastic box or the like is installed inside the main frame as a trash container.
