Embodiments for Carrying Out the Invention

[0018] [1] Embodiments of the present invention will be described with reference to the drawings.

[0019] All the drawings relate to a garbage storage device as an example of an embodiment of the present invention.

[0020] (1) This garbage storage device has an upward opening at the upper opening B3 and can stand independently. Inside the box-shaped part B2 with a substantially square horizontal cross-section on the base part B1 of the base B, a garbage bag G made of plastic film or other garbage bags, etc. are stored, and garbage W such as paper towels and other paper scraps put into the garbage bag G can be compressed. The garbage bag G and the garbage W are schematically shown in FIGS. 2, 3, 4, 5, 7, and 8. In FIGS. 2, 3, and 8, the garbage bag G is indicated by hatching.

[0021] (2) On the left and right side walls of the box-shaped part B2, guide parts D are respectively provided at the middle position in the front-rear direction.

[0022] Each of the left and right guide parts D consists of a vertically long guide groove part Ds in the vertical direction provided on the inner side of the box-shaped part B2 and a vertically long guide hole Dh formed at the center in the front-rear direction of the groove bottom part Ds1 of the vertically long guide groove part Ds and communicating with the outside of the side of the box-shaped part B2. The vertically long guide groove part Ds has a rear groove side wall part Ds2 and a front groove side wall part Ds2. As shown in FIGS. 1 and 6, the rear groove side wall part Ds2 has a wider horizontal width than the front groove side wall part Ds2 and projects inward of the box-shaped part B2.

[0023] On the upper side of the rear groove side wall part Ds2 of the rear groove bottom part Ds1 and the rear groove side wall part Ds2 (the part forming a substantially L-shaped horizontal cross-section by both of them) constituting the rear part side of the left and right vertically long guide groove parts Ds, a groove side wall extension part Ds3 is extended so as to curve backward upward.

[0024] (3) At the central part on the front outer side of the box-shaped part B2, a frame guide rail Rf is provided upright in the vertical direction.

[0025] At the central part in the left-right direction of the front connection part F1 of the horizontal frame F composed of a left arm part F2 and a right arm part F2 extending backward from the left and right ends of the front connection part F1 of the slide body Lf that can move up and down supported by the frame guide rail Rf, it is fixed.

[0026] At the base ends of the left and right arm portions F2 of the horizontal frame F, sliders S that are guided by the vertically long guide holes Dh and move up and down are fixed.

[0027] On the (right) side of the frame guide rail Rf on the front outer side of the box-shaped portion B2, a pulley guide rail Rp is provided upright in the vertical direction. A pedal Pd for depressing is coupled to a pulley Pu fixed to a pulley slide body Lp that is supported by the pulley guide rail Rp and can move up and down. One upper end of a rope Re that is hung below the pulley Pu is fixed to the upper part of the box-shaped portion B2, and the other upper end of the rope Re is fixed to the central portion in the left-right direction of the front connection portion F1 of the horizontal frame F.

[0028] At the upper central end portion on the front outer side of the box-shaped portion B2, a winding spring device Rw is fixed so that a spring Rw1 can be pulled out downward, and the lower end portion of the pulled-out spring Rw1 is fixed to the central portion in the left-right direction of the front connection portion F1 of the horizontal frame F.

[0029] In a state where no depressing force or the like is applied to the pedal Pd, due to the spring winding force of the winding spring device Rw, the horizontal frame F with the slider S fixed to the base ends of the left and right arm portions F2 and the pulley Pu with the pedal Pd are each located at the upper end.

[0030] When the pedal Pd coupled to the pulley Pu is depressed, the horizontal frame F descends, and the spring Rw1 of the winding spring device Rw is pulled out downward. The descending height of the horizontal frame F is twice the height at which the pedal Pd is depressed.

[0031] When the depressing force on the pedal Pd is released, the spring Rw1 is wound by the winding spring device Rw, and the horizontal frame F returns to the upper position, which is the original position.

[0032] The mechanism for lowering the horizontal frame F centering on the pulley Pu with the pedal Pd is the lowering drive part, and the mechanism for raising the lowered horizontal frame F centering on the winding spring device Rw is the raising drive part, and the lowering drive part and the raising drive part have a common part.

[0033] This garbage storage device can be configured to have an outer cover body (e.g., cylindrical or box-shaped) that covers the downward driving part, upward driving part, horizontal frame F, vertical guide groove part Ds, etc. on the outer peripheral side of such a box-shaped part B2. When this garbage storage device has an outer cover body, a slit part for the base side of the pedal Pd to move up and down can be provided at the front side part of the outer cover body. In that case, cover bodies Ps for the outer cover body slit parts to cover both the left and right sides of the slit part are shown by two-dot chain lines in FIGS. 1, 2, and 4 to 7.

[0034] (4) Inside the box-shaped part B2 (including above it), there are a rear movable frame body M and a front movable frame body N that constitute an opening holding part capable of holding the vicinity of the opening G1 of the garbage bag G in an open state.

[0035] Both the rear movable frame body M and the front movable frame body N are each composed of one and the other rotating arm-shaped parts along two of the three sides of a square and a connecting part along the remaining one side, forming a semi-frame shape in which both ends of the connecting part are connected to the tips of both rotating arm-shaped parts.

[0036] (4-1) The rear movable frame body M is rotatably supported with respect to a slider S (fixed to the base ends of the left and right arm parts F2 of the horizontal frame F) that is guided by a vertically long guide hole Dh and moves up and down at the bases of the left and right rear rotating arm-shaped parts Mh, and moves up and down together with the slider S.

[0037] The left and right rear rotating arm-shaped parts Mh are rotatably supported at the base in an upward state from the base to the end, and the upper part of the base is biased by a kick spring K in a direction to rotate rearward. Biasing bodies such as the kick spring K are preferably provided on both the left and right sides, but are not necessarily limited to both sides.

[0038] Except when located at the upper part, the rear rotating arm-shaped part Mh is guided by both side walls of the vertically long guide groove part Ds as shown in FIGS. 5 and 7, and moves up and down in an upright state or a state slightly tilted rearward by the biasing force.

[0039] When the rear rotating arm-like part Mh is located at the upper part as shown in FIG. 4, it is guided by the vertically long guide hole Dh and is in a state of being tilted backward by the biasing force with respect to the slider S located at the upper part, and the rear part side of the groove side wall part Ds2 is supported forward by the groove side wall extension part Ds3 extending upward.

[0040] A flat pressing plate C is fixed above the upper side of the rear connecting part Mk in a state where the rear rotating arm-like part Mh is upward from the base to the end. The pressing plate C is for pressing the contents accommodated in the garbage bag G.

[0041] As shown in FIGS. 3 to 5, 7 and 8, at the left and right end parts of the rear part of the pressing plate C, there are holding parts H that can hold the vicinity of the opening G1 of the garbage bag G by a plurality of elastic tongue pieces respectively.

[0042] (4-2) The front movable frame-like body N is rotatably supported inside the rear rotating arm-like part Mh in the box-like part B2 with respect to the slider S at the bases of the left and right front rotating arm-like parts Nh, and moves up and down together with the rear movable frame-like body M.

[0043] Since the front rotating arm-like part Nh is located inside the box-like part B2 rather than the groove side wall part Ds2 on the front side of the vertically long guide groove part Ds, it is not restricted by the rear groove side wall part Ds2. However, the length from the base to the end of the front rotating arm-like part Nh is slightly longer than the horizontal distance between the vertically long guide hole Dh and the inner surface of the front wall excluding the upper part of the box-like part B2, and the upper part is biased forward by the kick spring K with respect to the rotation axis of the base. Therefore, except for the upper part as shown in FIG. 4, as shown in FIGS. 5, 7 and 8, it moves up and down in a state of being slightly tilted upward from the base to the end.

[0044] The inner surface of the front wall of the box-like part B2 is inclined slightly forward from the lower end upward, spreads forward at a sharp angle near the upper end part to form the front upper step part B4, and further rises vertically to reach the upper end.

[0045] According to such a shape of the inner surface of the front wall of the box-shaped portion B2, as the front movable frame-like body N moves upward from the lower part, the upward inclination angle of the front rotating arm-like portion Nh gradually decreases, and the front movable frame-like body N gradually expands forward. Near the upper end portion, the front movable frame-like body N horizontally expands forward, and at the upper end portion, the front connecting portion Nk is supported on the upper front portion B4 as shown in FIGS. 3 and 4.

[0046] At the left and right end portions of the front connecting portion Nk, which is a connecting portion of the front movable frame-like body N, there are holding portions H that can hold the vicinity of the opening G1 of the garbage bag G by a plurality of elastic tongue pieces respectively.

[0047] As shown in FIGS. 3 to 5, 7 and 8, the body portion and the bottom portion of the garbage bag G are positioned inside the box-shaped portion B2 from between the pressing plate C and the front connecting portion Nk, and the rear portion of the opening G1 of the garbage bag G is held by the holding portions H at the left and right end portions of the rear portion of the pressing plate C so as to cover the upper portion from the front side of the pressing plate C, and the front portion of the opening G1 of the garbage bag G is held by the holding portions H at the left and right end portions of the front connecting portion Nk, whereby the bottom portion of the garbage bag G can be supported on the inner bottom surface of the box-shaped portion B2.

[0048] The pressing plate C moves up and down together with the slider S and the rear rotating arm-like portion Mh and the front rotating arm-like portion Nh (i.e., the opening holding portion), and by descending from the upper position, the contents accommodated in the garbage bag G can be pressed through the garbage bag G or directly.

[0049] (4-3) As described above, when the rear connecting portion Mk is located at the upper portion, it tilts upward and rearward from the base portion toward the end portion, and is supported between the ends of the left and right rear rotating arm-like portions Mh that are substantially upright upward or slightly rearwardly inclined at a position below the upper portion.

[0050] On the other hand, the front connecting portion Nk is supported between the ends of the left and right front rotating arm-like portions Nh that are shorter than the rear rotating arm-like portion Mh, and the front rotating arm-like portion Nh is horizontal when located at the upper portion, and inclines forward from the base portion toward the end portion at a position below the upper portion.

[0051] Therefore, regardless of whether the rear movable frame body M and the front movable frame body N are located at any position in the vertical direction, the vicinity of the opening G1 of the garbage bag G held at the holding portions H at the left and right end portions at the rear of the pressing plate C is located upward on the rear side, and the vicinity of the opening G1 of the garbage bag G held at the holding portions H at the left and right end portions of the front connecting portion Nk is located slightly lower than the pressing plate C on the front side.

[0052] When the rear movable frame body M and the front movable frame body N are located at the upper end portion which is the garbage input position, as shown in FIG. 4, the vicinity of the opening G1 of the garbage bag G is raised upward on the rear side where the pressing plate C is located, and the horizontal opening dimension between the pressing plate C and the front movable frame body N becomes the maximum.

[0053] In accordance with this, as shown in FIG. 2, this garbage storage device has an upper cover portion V which covers the upper opening of the box-shaped portion B2. The upper cover portion V raises the rear portion and provides a garbage input port V2 which extends over the front opening of the rear standing upper portion V1 and the upper opening at the front portion.

[0054] (4-4) As shown in FIGS. 1 to 4, with the pedal Pd, the horizontal frame F, the slider S fixed to the base end portions of the left and right arm portions F2 of the horizontal frame F and moving up and down, and the rear movable frame body M, the pressing plate C and the front movable frame body N at the upper end position, while the garbage bag G is held in an open state by the holding portions H at the left and right end portions of the pressing plate C which is fixed to the rear connecting portion Mk supported by the left and right rear rotating arm-like portions Mh standing up in a rearward inclined state and is inclined rearward, and the holding portions H at the left and right end portions of the front connecting portion Nk supported by the horizontal left and right front rotating arm-like portions Nh, the pedal Pd is depressed.

[0055] As the position of the pedal Pd becomes lower, the rear movable frame body M and the front movable frame body N descend. As shown in FIG. 5, the left and right rear pivoting arm portions Mh pivot forward to become substantially upright, the pressing plate C moves to the front center portion in the front-rear direction and becomes substantially horizontal, and the front connecting portion Nk retreats from the upper front portion B4 and gradually retreats along the inner surface of the front wall of the box-shaped portion B2 while descending in a state inclined forward and upward. The garbage bag G has its longitudinal dimension in the front-rear direction of the opening G1 reduced and the overall vertical dimension thereof also reduced.

[0056] When the position of the pedal Pd reaches the lower end position, the rear movable frame body M and the front movable frame body N descend to the lower end position. As shown in FIGS. 6 to 8, the garbage bag G has its longitudinal dimension in the front-rear direction of the opening G1 reduced, and the overall vertical dimension thereof is further reduced. The pressing plate C efficiently compresses the contents accommodated in the garbage bag G between the pressing plate C and the bottom surface of the box-shaped portion B2 through or directly through the garbage bag G.

[0057] When the depression of the pedal Pd is released, the spring Rw1 is wound up by the winding spring device Rw, and the horizontal frame F, the rear movable frame body M, and the front movable frame body N return to the upper end position, which is the original position, i.e., the position shown in FIGS. 1 to 4.

[0058] When removing and discarding the garbage bag G that has sufficiently accommodated the garbage W from the opening holding portion at the upper position, in order to take out the garbage bag G while avoiding the pressing plate C, the rear movable frame body M is manually rotated forward as much as possible, the holding by each holding portion H is released, and the garbage bag G can be taken out.

[0059] [2] The embodiments of the present invention will be further described including forms other than the above.

[0060] (1) The garbage storage device of the present invention can compress the garbage accommodated in the garbage bag, has an opening holding portion capable of holding the vicinity of the opening of the garbage bag in an open state, and has a pressing plate for pressing the contents accommodated in the garbage bag with the vicinity of the opening held by the opening holding portion. It has a guiding part for guiding so that both the opening holding part and the pressing plate can move up and down together.

[0061] (2) The target garbage is mainly waste that is relatively easy to compress. In a non-compressed state, it is difficult to accommodate a large amount in a garbage bag, but it becomes easy to accommodate a large amount in a garbage bag by compression. Examples include used paper towels and other paper scraps, but it is not limited to these.

[0062] (3) As the garbage bag, for example, a bag made of a plastic film can be used, but it is not limited to this.

[0063] (4) The opening holding part can hold the opening of the garbage bag in an open state at least when the opening holding part guided by the guiding part is located at the upper part (the garbage input position into the garbage bag) and can move up and down.

[0064] (4-1) The opening of the garbage bag whose opening part vicinity is held by the opening holding part shall be in an open state at any up and down position where the opening holding part is guided by the guiding part and moves (including those where the degree of opening changes [for example, at the position where the contents accommodated in the garbage bag are pressed down by the pressing plate, the opening is small]). In addition, for example, when the opening holding part is not located at the upper part (for example, at a position below the upper position, at a position below the upper and lower middle position, at the lower end position, or at the position where the contents accommodated in the garbage bag are pressed down by the pressing plate), the opening of the garbage bag can be in a substantially closed state (at least a state where air can be discharged from the garbage bag through the opening).

[0065] (4-2) The opening holding part (including the pressing plate) can have holding positions (for example, holding positions that can respectively hold at least four positions spaced apart from each other in the circumferential direction near the opening of the garbage bag, such as holding positions that can elastically sandwich or hold near the opening of the garbage bag, holding positions that can hold each position near the opening of the garbage bag by tying, holding positions that can hold each position near the opening of the garbage bag by binding, a through hole, and a fitting body (preferably connected to the opening holding part by a string or a belt-like connecting material, etc.) made of a material having rubber-like or other elasticity that can be fitted into and removed from the through hole, and holding positions that can hold the fitting body in a state of sandwiching the opening of the garbage bag by fitting it into the through hole, etc.), but is not limited thereto. Some or all of the holding positions can also be, for example, those that can elastically hold a required length portion along the opening of the garbage bag.

[0066] (4-3) The opening holding part can be, for example, a frame body or a required part of the pressing plate that is provided so as to be movable up and down by a guide part and has the above-mentioned holding positions.

[0067] The guide part can be, for example, a base body of a garbage storage device (for example, a base body having an upward-opening box-shaped part and capable of standing independently) having guide parts on both sides (for example, left and right), or a standing part provided with a guide part can be provided on both sides (for example, left and right) of the base part.

[0068] Examples of the guide part can include a vertically long guide hole, a vertically long groove-shaped part, a vertically long ridge part in the vertical direction, a vertically long shape part with an L-shaped horizontal cross section, etc., but are not limited thereto. Two or more of these can also be used as guide parts that respectively guide in parallel.

[0069] The frame-shaped body as described above can be guided by a vertical guide portion and move up and down. A movable frame-shaped body that can rotate (generally around a horizontal axis) with respect to the guide portion is preferable, but it is also possible to use a fixed frame-shaped body whose angle around the horizontal axis with respect to the guide portion substantially does not change. Both the movable frame-shaped body and the fixed frame-shaped body can be in the form of a half-frame along three sides of a square or in other forms of half-frames, but it is not necessarily limited to this.

[0070] (4-4) Examples of the half-frame-shaped movable frame-shaped body include those having a half-frame shape composed of rotating arm-shaped portions on both sides and a connecting portion connecting the ends of both rotating arm-shaped portions. More specifically, for example, it consists of one and the other (for example, the left and right) rotating arm-shaped portions along two sides of three sides of a square and a connecting portion along the remaining one side, and forms a half-frame shape in which both ends of the connecting portion are connected to the tips of both rotating arm-shaped portions. However, as described above, the form of the half-frame is not limited to this.

[0071] Such a half-frame-shaped movable frame-shaped body can rotate around the horizontal axis (for example, the left-right horizontal axis) in both side directions of the base body with respect to both guided bodies (for example, the left guided body and the right guided body, for example, the left and right guided sliders) respectively guided by the vertical guide portions provided on both sides (for example, the left and right sides) of the base body of the garbage storage device. The base end portions, which are the free ends of both rotating arm-shaped portions (for example, the left and right rotating arm-shaped portions), can be connected respectively.

[0072] Examples of the half-frame-shaped fixed frame-shaped body include those having a half-frame shape composed of arm-shaped portions on both sides and a connecting portion connecting the ends of both arm-shaped portions. More specifically, for example, it consists of one and the other arm-shaped portions along two sides of three sides of a square and a connecting portion along the remaining one side, and forms a half-frame shape in which both ends of the connecting portion are connected to the tips of both arm-shaped portions. The base end portions, which are the free ends of both arm-shaped portions, are fixedly connected respectively to both guided bodies respectively guided by the vertical guide portions provided on both sides of the base body of the garbage storage device. However, as described above, the form of the half-frame is not limited to this.

[0073] (4-5) As an example of configuring the opening holding part with a semi-frame-shaped frame body, on one side and the other side in a direction orthogonal to the vertical guide parts provided on both sides (for example, the left and right sides) of the base body of the dust collection device (for example, in the front-rear direction), a semi-frame-shaped movable frame body can be provided respectively, a semi-frame-shaped fixed frame body can be provided respectively, or a semi-frame-shaped movable frame body and a semi-frame-shaped fixed frame body can be provided.

[0074] (4-5-1) In these cases, a pressing plate for pressing the contents accommodated in the dust bag can be coupled to a connecting part or other locations that connect the ends of both arm-shaped parts (including the rotating arm-shaped parts) in the frame body on one side. Alternatively, the pressing plate can be provided separately from the opening holding part (for example, on another semi-frame-shaped frame body), and the opening holding part and the pressing plate can be guided so as to be able to move up and down together by the guide part.

[0075] The pressing plate can be, for example, plate-shaped or grid-shaped, and when it is guided by the guide part and descends together with the opening holding part, it is preferable that the pressing plate presses the contents accommodated in the dust bag on the lower surface orthogonal to or corresponding to the vertical direction of the pressing plate (for example, the horizontally-shaped lower surface).

[0076] When the pressing plate is coupled to the semi-frame-shaped movable frame body that constitutes the opening holding part, when the movable frame body is in the upper position, the movable frame body maintains a rotation angle at which the dust bag holding the vicinity of the opening can open as wide as possible and it is easy to throw in dust, and by being guided by the guide part and descending, the movable frame body becomes a rotation angle suitable for the pressing plate to press the contents accommodated in the dust bag (for example, a rotation angle at which the lower surface is horizontally-shaped), which is preferable.

[0077] When the pressing plate is coupled to a semi-frame-shaped or other fixed frame body that constitutes the opening holding part, it is desirable that the pressing plate is coupled at an angle and position as suitable as possible for pressing the contents accommodated in the dust bag.

[0078] (4-5-2) Further, when at least one of the semi-frame-shaped frame bodies constituting the opening holding part is a movable frame body, the semi-frame-shaped movable frame body can be biased by a biasing body (for example, a torsion kick spring) in a direction in which the opening of the garbage bag whose vicinity of the opening is held by the opening holding part opens or the opening widens. In that case, when the opening holding part rises from the lower position to the upper position where garbage is put into the garbage bag, the movable frame body biased by the biasing body rotates so that the opening of the garbage bag opens or the opening widens, making it easier to put in garbage. In that case, at the lower position, the opening of the garbage bag can be made to shrink more than at the upper position, and the garbage compression effect of pressing the contents accommodated in the garbage bag by the pressing plate can be enhanced as much as possible.

[0079] (4-5-3) Further, when the opening holding part is constituted by a semi-frame-shaped movable frame body on one side and a semi-frame-shaped movable frame body on the other side, the rotation axes of both movable frame bodies can be made common or the rotation shafts can be shared.

[0080] (4-6) When the opening holding part is constituted by semi-frame-shaped frame bodies (movable frame bodies or fixed frame bodies) provided on one side and the other side in a direction orthogonal to both side directions of the base body of the garbage storage device in which guide parts are provided on both sides as described above, for example, the pressing plate is coupled to the semi-frame-shaped frame body on one side, and a part near the opening of the garbage bag (for example, each of two locations separated by about one-fourth of the entire circumference along the opening edge or a portion covering those two locations) is held by the frame body on one side, and a part corresponding to the above-mentioned part near the opening of the garbage bag (for example, each of two locations separated by about one-fourth of the entire circumference along the opening edge or a portion covering those two locations) is held by the frame body on the other side.

[0081] In this way, the opening holding part composed of the two frame-like bodies can hold the vicinity of the opening of the garbage bag, and the body part (the part between the upper opening and the bottom) and the bottom of the garbage bag can be located below the inner sides of the two frame-like bodies.

[0082] The lower part of the garbage bag can be supported by a lower support part (for example, the bottom of the box-shaped part of the upper opening in the base body) in the base body of the garbage collection device. The pressing plate can press and compress the contents contained in the garbage bag through the garbage bag or directly between it and the bottom of the box-shaped part. Note that the opening holding part can be composed of, for example, a single frame-like body extending over the entire circumference, the pressing plate is coupled to the frame-like body, and the vicinity of the opening of the garbage bag is held by the frame-like body.

[0083] (4-7) In a state where the opening holding part is located at the upper part among the vertical positions guided and moved by the vertical guide part, the garbage bag can be held in an open state at the upper part, that is, a state where garbage can be put into the garbage bag. In this state, a part of the vicinity of the opening of the garbage bag held by the opening holding part on one side and the pressing plate can be located above a part of the vicinity of the opening of the garbage bag held by the opening holding part on the other side.

[0084] (4-7-1) For example, semi-frame-like movable frame-like bodies or fixed frame-like bodies are provided on one side and the other side respectively to form the opening holding part.

[0085] In that case, the bases of the two arm-like portions of the frame body on one side and the bases of the two arm-like portions of the frame body on the other side are respectively close to each other (for example, the base of the arm-like portion on one side is provided near the base of the arm-like portion on the other side, or they are concentric and adjacent in the axial direction). In the frame body on one side, the two arm-like portions rise upward on the end side with respect to the base, and the connecting portion connecting the ends of the two arm-like portions can be located upward. Further, in the two arm-like portions of the frame body on the other side, the end side extends horizontally or (for example, upward) inclinedly to the other side with respect to the base, and the connecting portion connecting the ends can be separated from the base in the horizontal direction or (for example, upward) inclined direction to the other side.

[0086] Furthermore, the connecting portion or the pressing plate of each frame body can hold the vicinity of the opening of the garbage bag, and the pressing plate can be coupled to the frame body on one side (for example, its connecting portion).

[0087] In this case, for example, the vicinity of the opening of the garbage bag held by the connecting portion of the frame body on one side and the pressing plate can be located about 0.2 to 1.5 times, preferably about 0.5 - 1 times, above the length of the arm-like portion of the frame body than the vicinity of the opening of the garbage bag held by the connecting portion of the frame body on the other side.

[0088] That is, when viewed from the other side, the vicinity of the opening of the garbage bag rises upward on the side where the pressing plate is located, and the horizontal opening dimension between the other side and the one side can be made shorter than twice the length of the arm-like portion of the semi-frame-shaped frame body. Accordingly, the garbage storage device of the present invention can have an upper cover portion that covers the upper part and opens a garbage inlet on one side.

[0089] (4-7-2) When the semi-frame-shaped frame body on the one side is a movable frame body, in the state where the movable frame body constituting the opening holding part is located at the upper part as described above, both of its arm-shaped parts are supported from the one side to the other side by a part of the base body such as a part (for example, the upper part) of the guide part (urged toward the one side by an urging body as necessary), so that the end parts of both arm-shaped parts rise upward, and the connecting part connecting the end parts of both arm-shaped parts can be located upward.

[0090] As the movable frame body on the one side constituting the opening holding part descends from the state of being located at the upper part as described above and the pressing plate rotates so as to move from the one side toward the other side (preferably, from the state where the rotating arm-shaped part is inclined to the side opposite to the other side and the opening of the garbage bag is open, the rotating arm-shaped part rotates toward the other side and becomes, for example, vertical, thereby reducing the opening of the garbage bag), the pressing plate can more efficiently press and compress the contents accommodated in the garbage bag.

[0091] When removing and discarding a garbage bag sufficiently filled with garbage from the opening holding part at the upper position, it can be effective to be able to manually rotate the semi-frame-shaped movable frame body on the one side as much as possible to the other side when taking out the garbage bag while avoiding the pressing plate.

[0092] (4-7-3) Also, when the semi-frame-shaped frame body on the other side is a movable frame body, as the movable frame body constituting the opening holding part descends from the state of being located at the upper part as described above, (by the connecting part connecting the end parts of both arm-shaped parts of the movable frame body being pushed toward the one side by a part of the base body that inclines downward toward the one side, etc.), the movable frame body rotates toward the one side to reduce the opening of the garbage bag, and the pressing plate can more efficiently press and compress the contents accommodated in the garbage bag.

[0093] In this case, the horizontal distance between the pressing plate and the vicinity of the opening of the garbage bag held at the connecting part of the other frame-shaped body can be, for example, about 0.2 to 1.5 times, preferably about 0.5 - 1.2 times the length of the arm-shaped part of the semi-frame-shaped body.

[0094] (4-7-4) One side of the semi-frame-shaped body constituting the opening holding part has a pressing plate. When the opening holding part is in a state located at the lower part among the vertical positions guided and moved by the guide part, In the other semi-frame-shaped body constituting the opening holding part, the horizontal distance between the position holding a part near the opening of the garbage bag and the pressing plate is made smaller than the width of the pressing plate in the horizontal direction or not having such a distance, so that the pressing plate can more efficiently press and compress the contents accommodated in the garbage bag.

[0095] (5) The garbage collection device can be provided with a lowering drive part for driving the opening holding part to lower and a raising drive part for driving the lowered opening holding part to rise.

[0096] The lowering drive part and the raising drive part can share part or all of them.

[0097] Examples of the lowering drive part and the raising drive part include stepping on a manually operated stepping part (pedal), pressing a pressing part, rotating a rotary handle, etc., using a slider, a guide rail, and a pulley device to drive the opening holding part to lower while pulling out the spring of the winding spring, and releasing the operating force on the stepping part, etc. in a state where the opening holding part has lowered, so that the opening holding part is driven to rise by the winding force of the winding spring and returned to the upper position. However, it is not limited to this. For example, an electric motor can also be used as the drive source of the lowering drive part and the raising drive part.

[0098] The garbage storage device of the present invention can be provided with, for example, a guide part that supports an opening holding part so as to be vertically movable, and has a box-shaped base body capable of storing a garbage bag inside. All or part of a lowering drive part and a raising drive part are provided outside the box-shaped base body, and it can have an outer cover that covers these lowering drive part and raising drive part.

[0099] In addition, the operation of the lowering drive part can be made possible only for a specific person by using security means such as a key, a password, or the like. For example, a pedal part (a pedal or the like that can be stored in a compact form such as being folded if necessary) stored inside the outer cover can be used only by a specific person by opening an opening / closing lid that can be opened and closed with a key, a dial key, or the like.
