Description

  The present invention relates to a dust box to which a garbage bag is mounted, and more particularly to a dust box that can be mounted with two garbage bags and is suitable for separation and collection.

  Many dust boxes are placed in places where many people come and go, such as stations, downtowns, sightseeing spots, parks, movie theaters, theaters and the like. As the dust box, a net, a cylindrical body made of plastic, or a rectangular body is widely used. The upper end of the dust bag is folded and attached to the upper edge of the dust box, and the dust is put into the attached dust bag.

  In this way, if garbage is put in the garbage bag attached to the dust box, the garbage can be collected by exchanging the garbage bag, and the collection of the garbage becomes easy. In addition, moisture, small dust, and the like do not leak or scatter from the dust box, and contamination around the dust box is prevented.

  Recently, separation and collection have been promoted for the purpose of collection and disposal of waste and reuse of resources, and a dust box in which a plurality of garbage bags can be attached for separation and collection is known.

  In the dust box for separation, a plurality of normally two spaces are set in one dust box, and a garbage bag can be attached to each. As described above, the garbage bag is attached to the dust box by folding the upper end of the opening and engaging the upper end of the opening with the upper edge of the dust box. When two garbage bags are attached to one dust box, the upper open end of the garbage bag cannot be locked to the upper edge of the dust box on the adjacent side of the two garbage bags. For this reason, the upper end of the opening of the garbage bag that is not locked hangs down and closes the opening of the garbage bag. In addition, when the upper end of the garbage bag hangs down and there is a gap between the two garbage bags, the garbage is dumped in this gap and accumulates in the dust box itself, not in the garbage bag. It is necessary to dispose of the accumulated waste, and the workability of collecting the waste is lowered.

  In order to enable the entire periphery of the upper end of the garbage bag to be locked, a partition plate that divides the inside of the dust box into two spaces may be provided near the center of the dust box (for example, Japanese Utility Model Publication No. 57-018322, Japanese Utility Model Application No. 64). No. 0180007), a dust box for sorting is known in which a partition rod is placed over the opening of the dust box (for example, Japanese Utility Model Publication No. 62-176102).

  Japanese Patent No. 3040712 describes a dust box in which two dust bag holding frames are provided inside the upper end of the opening of the dust box. Each garbage bag holding frame has a U-shaped outer frame with its end rotatably attached to the side wall of the dust box, and a U-shaped with its end rotatably attached to the leg of the outer frame inside the outer frame. It is composed of a combination with the inner frame. In this dust box, each garbage bag is stored in a space defined by each garbage bag holding frame, and the upper end of the opening of the garbage bag is folded back by a U-shaped outer frame and an inner frame, respectively. The inner frame is held and locked between the outer frame and the side wall of the dust box, and the U-shaped inner frame is moved down and locked between the inner frames. Since the locking protrusions (protrusions) are formed on the outer surface of the inner frame, the upper end of the garbage bag is firmly held between the inner frames by the locking of the locking protrusions. The sagging of the upper end of the opening of the garbage bag on the adjacent side of the bag is prevented.

  In the configuration in which the inside of the dust box is divided into two spaces by the partition plate (Japanese Utility Model Publication No. 57-018322, Japanese Utility Model Publication No. 64-018007, etc.), different sizes of spaces are set depending on the partition plate. Here, if the partition plate is formed separately from the main body so that it can be detached (Japanese Utility Model Publication No. 57-18322), one large garbage bag for specific waste that is produced in large quantities by removing the partition plate It can also be used as a dedicated dust box equipped with, and can be used for both separate collection and normal collection. However, the partition plate may be lost when not in use.

  In a configuration in which a partition bar is bridged (such as Japanese Utility Model Publication No. 62-176102), the position of the partition bar can be arbitrarily changed, and the sizes of the two spaces can be arbitrarily set. Even in this configuration, except for the partition bar, it can be used as a dedicated dust box equipped with one large garbage bag, and is highly versatile. However, even in this configuration, the partition bar may be lost when not in use.

  In the dust box of Japanese Patent No. 3040712, the inner frame is slidably attached to the inner side of the outer frame, and the size of the two spaces can be arbitrarily set by sliding the two inner frames in the same direction. Then, the size of the two spaces is set according to the amount of garbage to be sorted, and the size corresponding to the size of the space (specifically, the size of the opening of the space) is the same size or different. Two trash bags of size are attached to the dust box and discarded separately. In this configuration, if one large garbage bag is locked by two outer frames without using two inner frames, it can be used as a dedicated dust box. Since one large garbage bag can be attached without removing the inner frame, the inner frame cannot be lost.

  Recently, various types of drinking water in PET bottles, cans, bottles, etc. (hereinafter referred to as “PET bottles” as appropriate) are sold and consumed in large quantities, and as a result, PET bottles are dumped in large quantities in dust boxes. Has been. Then, a leftover from a discarded plastic bottle or the like flows out and remains at the bottom of the garbage bag. When a hole or tear occurs in the garbage bag, it flows out from the hole or tear. By the way, since each of the above-mentioned dust boxes for separation is molded from plastic into a closed container shape with a bottom, leftovers leaking from the holes of the garbage bags and tears stay at the bottom of the dust box. Therefore, in the collection of garbage, not only lifting the garbage bag and collecting it, but also tilting the dust box to eliminate leftovers from the bottom of the dustbox, and washing the bottom to remove dirt from leftovers is necessary. . However, the subsequent work of removing leftovers and cleaning the container is a dirty work and is avoided.

  For example, in the dust box disclosed in Japanese Utility Model Laid-Open No. 64-018007, a communication hole that communicates two spaces is formed at the lower end of the partition plate in consideration of this point. A drain hole is provided at the bottom of the dust box, the bottom of the dust box is an inclined surface that descends toward the drain hole, and the drain hole is closed with a stopper from the outside. In this configuration, the leftovers leaked from the plastic bottles and the like discarded in the garbage bags installed in the two spaces flow along the inclined surface and stay in the vicinity of the drainage holes through the communication holes. Therefore, by removing the stopper and opening the drainage hole, the leftovers can flow out and the water injected for cleaning can be drained, and the subsequent work can be performed easily.

  However, since the drain hole is provided at the bottom of the dust box and is closed with a stopper from the outside, the stopper cannot be removed unless the dust box is tilted. If the dust box is tilted excessively or vigorously when the stopper is pulled out, there is a risk that the unreserved drink remaining at the bottom of the dust box will flow out beyond the upper end of the opening of the dust box.

  In addition, problems peculiar to dust boxes made of plastic containers have been pointed out. In other words, the plastic bottles and the like dumped in the garbage bags are irregularly stacked, and the garbage bags irregularly bulge outward (expand). In the dust box of a plastic container, there is no escape place for weight such as PET bottles, and the garbage bag is pressed against the side wall of the dust box and brought into close contact, so when you lift the garbage bag for collection, the garbage bag is in the bulging part Is rubbed and broken by the side wall of the dust box. Then, the leftover that has stayed at the bottom of the garbage bag is rapidly ejected from the broken hole. The eruption of leftovers from the break hole often occurs when the garbage bag crosses the upper edge of the opening of the dust box, not only contaminates the surroundings of the dust box, but also falls on the garbage collector who is lifting the garbage bag, It has become a big problem. Further, a dust box made of a plastic container occupies a large volume even when stacked and transported and stored, and there is a problem in transportability.

  There is also known a dust box which is not a plastic container but is configured by combining a frame (frame body) such as a steel pipe or a steel rod so as to be rotatable around a pivot (for example, Utility Model Registration No. 3044214, Japanese Patent Laid-Open No. Hei. 11-217102). This frame-shaped dust box can be locked in a state where the upper end of the garbage bag opening is stretched, so that the upper end of the garbage bag does not hang down and block the opening of the garbage bag. Furthermore, the collection of the garbage bags is easy, and there is little risk that the garbage bags will be broken during the collection, and the leftovers will be ejected. Moreover, since it can fold, it is excellent in a conveyance property.

  However, in the frame-shaped dust box, there is only one garbage bag to be attached, and since it is not configured to attach a plurality of garbage bags, a plurality of dust boxes must be provided for separate collection. Not suitable for separate collection. Although there is little risk of the garbage bag being broken during collection, if a hole or a tear is formed in the garbage bag due to the disposal of a plastic bottle or the like, the leftover will flow out and the surroundings of the dust box will be contaminated. Here, if the tray is disposed below the garbage bag, the surrounding contamination can be prevented for the time being. However, the left-over drink tray also serves as a garbage bag receiver, so that the bottom of the garbage bag is immersed in the left-over drink in the tray, and when you lift the garbage bag for collection, the leftover drinks dripping from the garbage bag. The surrounding pollution cannot be prevented.

Note that not only leftovers such as plastic bottles, but also garbage from homes and restaurants have the same problems as leftovers, and garbage can be discussed in the same way as leftovers. Therefore, in the following, it will be discussed including food waste by expressing it as a leftover (such as a plastic bottle).
Japanese Utility Model Publication No. 57-018322 Japanese Utility Model Publication No. 64-018007 Japanese Utility Model Publication No. 62-176102 Japanese Patent No. 3040712 Utility Model Registration No. 3044214 JP-A-11-217102

  The problem to be solved is that the upper end of the garbage bag can be securely locked, it is easy to transport and store, and it is excellent in versatility to be able to attach a single large garbage bag dedicated to specific garbage in addition to sorting and collection. There is no dust box.

  In the present invention, the component member is divided into four parts, a bottom frame, two side frames, a back frame, and a front frame, and these are locked and connected to be assembled. The left and right shoulders are used as the garbage bag locking parts, and the front frame has two frames. Each frame is restricted to turn in the push-in direction and turns to the front leg of the side frame. The main structure is that it can be locked.

  According to the first and second aspects of the present invention, since the constituent members are divided, a dust box that is easy to transport and store and excellent in transportability can be obtained. Then, the lower end of the leg portion is locked to the substantially rectangular bottom frame, and the substantially inverted U-shaped side frame is assembled to the bottom frame from the left and right, and the left and right ends are locked to the upper end of the leg portion behind the side frame. It can be assembled by assembling it by assembling the back frame with a substantially inverted U shape into the left and right side frames and locking each frame of the front frame to the front leg of each side frame. Instead, it can be assembled only by locking.

  Since the side frame on the left and right, the front frame on the front, and the rear frame on the back are built in around the bottom frame of the substantially rectangular shape, the dust box has a square or rectangular outer shape, the upper end of the two legs on the side frame, The garbage bag is attached by locking the folding of the upper end of the opening of the garbage bag at four points, that is, a locking part formed at the center and a shoulder on the frame of the front frame. Then, two combinations of the upper ends of the two leg portions of the side frame, the locking portion formed at the center portion of the back frame, and the shoulder portion on the frame of the front frame are formed in total, one on each side. Therefore, two garbage bags can be installed and used as a separate collection dust box. Here, each frame body of the front frame is allowed to rotate by restricting the rotation in the pushing direction, and the garbage bag is placed at the position where the frame body is pushed in using the clearance for rotation. If attached, a restoring force (elastic force) for returning the frame body to the original position acts on the upper opening end of the garbage bag, thereby reliably locking the upper opening end of the garbage bag. Therefore, there is no possibility that the opening of the garbage bag is blocked by the removal of the insertion and the upper end of the opening of the garbage bag hanging down.

  In addition, the upper end of the left and right side frames, ie, the upper and lower ends of the left and right side frames, ie, the upper and lower ends of the left and right side frames, are used in total. In addition, according to a general mounting method in which the upper end of the opening of the garbage bag is locked, a single large garbage bag can be mounted. Therefore, it can be used as a dedicated dust box equipped with one large garbage bag for a large amount of specific garbage, and a highly versatile dust box that can be used in both separate collection and normal collection is obtained. And even when used as a dust box for normal collection, there is no need to remove the back frame with the central folding part used for attaching garbage bags during sorting collection or the frame of the front frame. Never lose.

  In the separate collection, the upper end of the garbage bag is removed from the front frame by pushing the frame of the front frame using the gap for rotation to remove the upper end of the garbage bag from the front frame. Then, if the frame body of the front frame is rotated and escaped to the side, the front surface is opened, and the garbage bag is taken out from the dust box and collected by pulling forward. In a dust box consisting of a plastic container, the rubbing bag is easily damaged by rubbing against the side wall to be pulled up, whereas when it is pulled out to the front, it is difficult to cause damage due to rubbing with the side frame. If there is, the top of the left and right side frames is free, so if you spread the side frame left and right at the top, lift the garbage bag up slightly and pull it out toward you, the garbage bag will be damaged during collection. It can be avoided reliably. As described above, according to the present invention, the garbage bag can be easily collected without being damaged.

  The substantially rectangular bottom frame has a bottom surface that serves as a support surface of the garbage bag. The garbage bag is supported by the bottom surface (support surface) of the bottom frame and separated from a tray placed under the bottom surface (support surface). For this reason, even if a hole in the garbage bag or a leftover from leakage is retained in the tray, the bottom of the garbage bag is not soaked in the leftover in the tray. No dripping from the bottom of the bag, there is no worry of contaminating the surroundings.

  According to the third aspect of the present invention, the front frame is securely assembled without being easily detached because it is held and sandwiched by the side frame from above and below. Further, since the front frame has a closed loop shape, there is no possibility that the garbage bag will be caught and damaged during collection.

  According to the fourth aspect of the present invention, the connecting portion of the side frame functions as a stopper for restricting the rotation of the front frame in the push-in direction, and the restricted pivotable locking of the front frame is ensured with a simple configuration. Is done.

  According to the present invention described in claim 5, since the inserting direction of the bent piece is different and the pushing force to the bent piece does not act as the pulling force of the already attached bent piece, the side surface to the bottom frame The frame can be easily locked and connected.

  According to the sixth aspect of the present invention, since the swell of the garbage bag is prevented by the wall surface frame of the side frame, the rubbing with the side frame when the garbage bag is pulled out is alleviated, and the dust caused by the rubbing is reduced. Damage to the bag can be avoided.

  According to the seventh aspect of the present invention, since the tray is arranged in the dust box using the space below the bottom surface that supports the garbage bag, the tray is hardly displaced, and the tray is leaked from the garbage bag. It is possible to reliably receive leftovers, etc., and to prevent surrounding contamination due to dripping outside the tray.

  According to the present invention described in claim 8, it is not necessary to prepare a new garbage bag each time the garbage is collected by holding the roll-shaped garbage bag on the back frame shelf. If the tip of the roll-shaped garbage bag is locked to the protruding portion of the horizontal frame and pulled up, a single garbage bag is cut from the roll-shaped garbage bag along the perforation to obtain a garbage bag. A series of collection operations from bag collection to mounting is simplified.

  The dust box of the present invention has a substantially rectangular bottom frame having a bottom surface that serves as a support surface of a garbage bag to be mounted, a connection that connects two leg portions whose lower ends are locked to the bottom frame and the upper ends of the leg portions. Two substantially inverted U-shaped side frames provided with a portion, and a substantially inverted U-shaped shape whose left and right ends are locked to either the upper end of the leg portion behind the side frame or the rear end of the connecting portion A rear frame and a front frame locked to either the upper end of the leg part in front of the side frame or the front end of the connecting part, and the center part of the rear frame is bent downward to engage the garbage bag. The shoulders that serve as stop parts are formed on the left and right ends of the bent part, the front frame has two frames, and each frame is restricted from rotating in the push-in direction and can be rotated in the front-rear direction. Stopped and configured.

  FIG. 1 is an exploded perspective view showing an outline of a dust box 10 according to an embodiment of the present invention. In the present invention, its constituent members are a bottom frame 20, two side frames 30 (30L, 30R), a back frame 40, The front frame 50 is divided into four parts, which are connected and assembled. 2 shows a perspective view of the dust box 10 assembled by incorporating the bottom frame 20, the side frame 30, the back frame 40, and the front frame 50, and FIGS. 3A and 3B are front views of the assembled dust box. The right side view is shown, and both are shown with two garbage bags 12 attached. Hereinafter, the configuration of each component will be described sequentially.

  First, the bottom frame 20 will be described. FIG. 4 is a perspective view of the bottom frame 20. As can be seen from FIG. 2, the bottom frame 20 is formed in a substantially rectangular shape having a bottom surface 22 that serves as a support surface of the garbage bag 12 to be mounted (see FIGS. 3A and 3B). On the upper surface of the rectangular frame 22a, a series of vertical frames 22b are erected and welded apart from each other by a predetermined distance. For example, the frame 22a is formed by bending a steel rod having a diameter of 8 mm into a rectangle, and the vertical frame 22b is used by cutting a steel rod having a diameter of 6 mm. Further, support frames 24L and 24R formed into a shape that lacks a part of one side of the rectangle are welded to the front and rear ends below the frame body 22a, with the notched side up. The two horizontal frame bodies 25-1 are installed on the front and rear ends of the support frame 22 on the lower surfaces of the left and right support frames 24L and 24R, and the two horizontal frame bodies 25-2 are installed on the intermediate portion of the support frame. Have been welded. For example, the support frames 24L and 24R are formed by bending a steel rod having a diameter of 6 mm, the horizontal frame 25-1 is a steel pipe having a diameter of 13 mm, and the horizontal frame 25-2 is a steel rod having a diameter of 6 mm. And use it. As will be described later, the lower ends of the front and rear leg portions of the side frame 30 are inserted into the end portions of the front and rear horizontal frame bodies 25-1 made of steel pipe, and the side frames are connected to the bottom frame 20.

  Furthermore, the steel plates 26L and 26R are installed and welded to the lower surfaces of the front and rear horizontal frame bodies 25-1, and the rollers 27 are separated from each other in the front and rear directions, and two on the lower surfaces of the steel plates 26L and 26R. Therefore, the bottom frame 20 can move in the front-rear direction (arrow direction), and the dust box 10 functions as a dust cart.

  In the configuration of the bottom frame 20, below the support surface 22, there are spaces 28 defined by the support frames 24L and 24R on the left and right sides, and the horizontal frame bodies 25-1 and 25-2 and the steel plates 26L and 26R on the lower surface. It is formed. In this space 28, a receiving tray 29 is disposed for PET bottles, cans, leftovers of bottles and garbage (leftovers etc.).

  FIG. 5 shows a perspective view of the tray 29. As shown in FIGS. 2 and 3A, the dust box 10 of the present invention is provided with two garbage bags 12, so that two trays 29 are arranged in the space 28 corresponding to the number of garbage bags. Is done. The tray 29 is molded from plastic and is reinforced by providing a flange 29a on the upper edge and an emboss 29b on the bottom surface. Usually, the two receiving trays 29 are the same in consideration of the convenience of molding and transportation. Further, a lateral groove 29c is formed in the tray 29 at the front end of the bottom surface, and the lateral groove 29c can be locked with the lateral frame body 25-1 of the bottom frame 20. If the saucer 29 is inserted into the space 28 and the lateral groove 29c is engaged with the lateral frame body 25-1 in front of the bottom frame 20 and disposed in the space, the saucer is placed in the lateral frame bodies 25-1, 25-2, The steel plates are supported by the steel plates 26L and 26R, and the left and right movements thereof are not only restricted by the left and right support frames 24L and 24R, but also the front and rear movements are restricted by the engagement between the horizontal grooves 29c and the horizontal frame body 25-1. Thus, the horizontal frame 25-1 of the bottom frame 20 is locked to the horizontal groove 29c of the tray 29 and functions as a stopper for the tray. Instead of arranging two small saucers 29, one large saucer may be arranged in the space 28.

  When the tray 29 is placed directly on the floor or the like below the support surface 22, a relative positional shift is likely to occur between the dust box 10 and the tray 29, so that any unsold beverages that have leaked from the garbage bag can be dropped on the tray. It easily falls on the floor and easily contaminates the surroundings of the dust box 10. However, as in the embodiment, if the space 28 for the receiving tray 29 is provided in the bottom frame 20 and the receiving tray is disposed in this space, leftovers and the like can be reliably dropped on the receiving tray and the surrounding contamination can be prevented. . In particular, since the horizontal frame body 25-1 of the bottom frame 20 is used as a stopper for the receiving tray 29, the receiving tray 29 can be removed from the space 28 even if an impact force in the front-rear direction is applied to the dust box 10 or the dust box is tilted in the front-rear direction. It does not jump out in the front-rear direction, and scattering such as leftovers in the saucer due to the saucer jumping out and coming off and surrounding contamination are prevented.

  Further, the space 28 is formed below the support surface 22 and is separated from the support surface 22 by a series of vertical frames 22b. And the garbage bag 12 is supported by the support surface 22, and the receiving tray 29 in the space 28 does not receive the garbage bag. For this reason, the tray becomes a receptacle for the garbage bag, and the bottom of the garbage bag is soaked in the leftover in the tray, and when the garbage bag is lifted for recovery, the leftover dripping from the garbage bag drops and contaminates the surroundings. The problem does not occur in the present invention, and in the present invention, the garbage bag can be collected without contaminating the surroundings. And although the post-work of removing the leftover from the tray 29 and washing the tray is necessary, the conventional post-work of washing the bottom by tilting the dust box made of a plastic container and removing the leftover from the bottom of the dust box. By comparison, the after work in the present invention is greatly improved.

  Next, the side frame 30 will be described. FIG. 6 shows a perspective view of the side frame 30. As shown in FIG. 6, the side frame 30 includes two left and right side frames 30L and 30R, and the side frames 30L and 30R are formed symmetrically. Hereinafter, the configuration of the right side frame 30R will be described, and the description of the left side frame 30L will be omitted.

  The side frame 30R is formed by bending a steel rod having a diameter of 8 m, for example, into a substantially inverted U shape including two leg portions 32a and a connecting portion 32b that connects the upper ends of the leg portions. A series of horizontal frame bodies 33 are installed on the outer surface between the two leg portions 32a so as to be separated from each other by a predetermined distance, and one vertical frame body made of the same material as the horizontal frame body 33 is formed at the center of the horizontal frame body 33. 34 is provided to form a side wall 34.

  The side frame 30 functions as an active member (connecting member) for the bottom frame 20 and a passive member (receiving member) for the back frame 40 and the front frame 50. That is, the side frame 30 is connected to the bottom frame 20 using both lower ends of the two leg portions 32a, and the back frame 40 is connected to the upper end of the back leg portion 32a1 of the two leg portions 32a. The front frame 50 is connected to the upper end of the leg portion 32a2 (see FIGS. 1 and 2).

  First, the connection method to the bottom frame 20 using the lower end of the leg portion 32a will be described. As can be seen from FIG. 6, the lower ends of the leg portions 32a1 and 32a-2 are both folded inward (bottom frame side 20). The bent frame 33 (33-1, 33-2) is inserted into and attached to the end (see FIG. 4) of the horizontal frame 25-1 made of a steel pipe of the bottom frame 20, whereby the side frame 30R. It is connected to the bottom frame 20.

  When assembling an object by inserting bent pieces into a steel pipe, if the mounting body has multiple bent pieces, for example, two bent pieces, after inserting one bent piece, the other When trying to insert a bent piece (for convenience of explanation, one bent piece is referred to as a bent piece 1 and the other bent piece 2), a bent piece that has been inserted while the bent piece 2 is being inserted. Often we experience that the piece 1 comes out and the folded piece 2 cannot be easily inserted. This occurs under the condition that the insertion direction of the bent pieces 1 and 2 is the same, and the mounting body is an integral body having the bent pieces 1 and 2, and a pushing force is applied to the bent piece 2 for insertion. Then, it is understood that an elastic force is generated in the mounting body which is an integrated object by the pushing force, and this elastic force acts as a pulling force on the bent piece 1 at a position separated from the bent piece 2.

  Therefore, in the dust box 10 of the present invention, the bent piece 33 formed on the side frame 30R is formed so that the insertion direction does not match by changing the bending angle before and after that. 7 (A) and 7 (B) are left side views of the side frame 30R with a part thereof broken. Specifically, FIG. 7 (A) is a leg portion 32a1 on the back as viewed from the arrow a in FIG. FIG. 7B shows the front leg portion 32a2 as viewed from the direction of arrow b in FIG. FIG. 7C is a plan view of the side frame 30R viewed from the direction c of FIG.

  The bent piece 33-1 of the back leg portion 32a1 is smaller than 90 ° which is a general bending angle, and the bent piece 33-2 of the front leg portion 32a2 is bent largely, respectively. Then, the insertion directions are changed by making the respective bending angles θ1 and θ2 different. Therefore, for example, after inserting the bent piece 33-1 on the back surface into the right end of the horizontal frame body 25-1 on the back surface of the bottom frame 20, the bent piece 33-2 on the front surface is connected to the horizontal frame body 25- on the front surface. Even if a bending force is applied to the bent piece 33-2 to cause insertion of the bent piece 33-2 and an elastic force is generated in the side frame 30R. Thus, the pulling force only generates a bending moment in the bent piece 33-1 and does not act as a force for pulling out the bent piece 33-1. Instead of pulling out, the bending moment acts to bend the bent piece 33-1 and firmly insert the bent piece 33-1 into the horizontal frame 25-1. Therefore, the continuous insertion of the bent pieces 33-1 and 33-2 to the front and rear horizontal frame bodies 25-1 can be performed without detachment of the already inserted bent pieces. Here, since the bending angles of the bending pieces 33-1 and 33-2 are different and the insertion directions do not match, it is necessary to insert the side frame 30R while slightly deforming the insertion. . However, the insertion method of the present invention can be performed much more easily when compared with the complexity of the conventional insertion method in which pressing is performed on another bent piece while preventing the already inserted bent piece from being detached.

  For example, when the bending angles θ1 and θ2 are θ1 = 90−a and θ2 = 90 + b, the bending pieces 33-1 and 33-2 can be inserted without requiring a large force if a = b. When a = b = 5, θ1 = 85 °, and θ2 = 95, good effects can be obtained. In addition, it is sufficient if the bending angles of the bent pieces 33-1 and 33-2 are made different from each other so that the insertion directions thereof do not coincide with each other. On the contrary, there is no problem even if the bending angle of the front bending piece 33-2 is reduced. Alternatively, θ1 = θ2 = 90 may be set, and the bent pieces 33-1 and 33-2 may be shifted and bent in a direction perpendicular to the paper surface.

  Next, a method for connecting the rear frame 40 to the upper end of the rear leg portion 32a1 and a method for connecting the front frame 50 to the upper end of the front leg portion 32a2 will be described. As can be seen from FIG. 7, a support tube 35-1 is welded to the upper end of the leg portion 32a1 on the back surface, and a support tube 35-2 is welded to the upper end of the leg portion 32a2 on the front surface. For example, the support cylinders 35-1 and 35-2 are formed of steel pipes similarly to the horizontal frame body 25-1 of the bottom frame 20, and steel pipes having a diameter of 10 mm are used. Here, as can be seen from FIGS. 7A, 7 </ b> B, and 7 </ b> C, the support cylinder 35-1 for the back frame 40 is positioned 90 ° inward with respect to the connecting portion 32 b of the side frame 30 </ b> R. The support cylinder 35-2 for the front frame 50 is attached to a position shifted by θ3 outward with respect to the connecting portion 32b, whereas the support cylinder 35-2 for the front frame 50 is attached to the upper end of the bent piece 33-1. Is not located directly above the bent piece 33-2 at the lower end. This θ3 is set to 45 ° in the embodiment.

  The reason why the mounting positions of the support cylinders 35-1 and 35-2 are thus different is that, as shown in FIG. 1, the back frame 40 is connected and fixed to the support cylinder 35-1. This is because the front frame 50 is rotatably connected to the support cylinder 35-2, and will be described in detail when the front frame 50 is described. As shown in FIGS. 7A and 7B, the back frame 40 is inserted into the support tube 35-1 from above, whereas the front frame 50 is sandwiched from above and below to the support tube 35-2. Since it is inserted, the support cylinder 35-2 for the front frame is formed longer than the support cylinder 35-1 for the back frame.

  The mounting position of the support cylinder 35-1 on the back frame is not limited to the illustrated position shifted inward by 90 ° with respect to the connecting portion 32b of the side frame 30R. For example, as shown by a one-dot chain line in FIG. In addition, it may be provided on an extension line of the connecting portion 32b. However, when the garbage bag 12 is attached at a position shifted 90 ° inward, the support cylinder 35-1 is located inside the garbage bag and does not contact the garbage bag, so that the support cylinder 35-1 damages the garbage bag. There is no fear. On the other hand, at the position of the extension line, there is a possibility that the support cylinder 35-1 may come into contact with the garbage bag and damage the garbage bag by the support cylinder 35-1. 35-1 is preferably provided. Moreover, although the support cylinder 35-1 is normally attached to the upper end of the leg part 32a of the side frame 30R, you may attach it to the rear end of the connection part 32b.

  The back frame 40 will be described. FIG. 8 shows a perspective view of the back frame 40. The back frame is formed, for example, by bending a steel material of 8 mm into a substantially inverted U shape and bending the center part downward. As can be seen from FIGS. 1 and 7C, the left and right ends 40a facing downward of the back frame 40 are respectively inserted into the support cylinders 35-1 (made of steel pipes) of the left and right side frames 30L and 30R. Thus, the rear frame 40 is connected to the side frame 30 and assembled. As can be seen from FIG. 2 and FIG. 3 (A), the garbage bag is formed by hanging the garbage bag 12 on the left and right shoulders 42a of the center bent portion 42 formed by bending the center portion of the back frame 40 downward. Therefore, the width L2 of the bent portion 42 is determined so that the distance L1 between the left and right ends 40a and the shoulder portion 42a is a length that allows the garbage bag 12 to be mounted comfortably. In addition, the center bending part 42 should just be a shape which can hang the garbage bag 12 on the shoulder part 42a of the right and left without difficulty, and is not limited to the substantially reverse U-shape shown in figure.

  In the embodiment, a shelf 44 obtained by bending a steel plate into an L shape is welded to the central bent portion 42 of the back frame 40. The free end 44a 'of the bottom plate 44a of the shelf 44 is bent upward, and a substantially U-shaped frame 46 is disposed on the bottom plate 44a with its left and right ends welded to the side wall 44b of the shelf. . For example, the frame body 46 is formed by bending a steel rod having a diameter of 4 mm, and further bent into a substantially triangular shape at a position obtained by dividing the overall length L2 into approximately four equal parts to form three projecting portions 46a. Provided. As can be seen from FIG. 3B, the frame body 46 is disposed so as to protrude from the shelf body with a gap remaining between the frame body 46 and the bent end 44a ′ of the shelf body 44. A free hole 44 c for the leg portion 32 a 1 of the side frame 30 is formed at the left and right ends of the bottom plate 44 a of the shelf body 44.

  The shelf 44 holds the garbage bag 12 that is used by being attached to the dust box 10, and the waste bag 12 is preferably used by breaking and separating the roll-shaped garbage bag 12 'from the perforation as the garbage bag 12. A waste bag 12 ′ is held on the shelf 44 and is on standby. As shown in FIG. 3 (B), in use, if the tip of the roll-shaped garbage bag 12 'passes through the gap between the bent end 44a' of the shelf 44 and the frame 46, it is pulled upward, The garbage bag is broken and separated from the perforation by the projecting portion 46a of the frame 46.

  In this way, by providing the rear frame 40 with the shelf 44 that holds the roll-shaped garbage bag 12 ', the trouble of preparing the garbage bag every time the garbage bag is collected can be saved, and from the collection to the installation of the garbage bag. A series of collection operations are simplified. Here, even if the shelf body 44 is provided on the rear frame 40, the garbage bag 12 is pulled out and collected at the time of garbage collection, so the shelf body 44 of the rear frame 40 does not become an obstacle to collecting the garbage. And since it is provided in the upper end of the back frame 40 corresponding to the position used as the dead space of the garbage bag 12, presence of the shelf 44 does not have a possibility of reducing the effective volume of a garbage bag. Further, the roll-shaped garbage bag 12 ′ held on the shelf 44 at the upper end of the back frame 40 was discarded because it is covered and isolated by the attached garbage bag 12 as shown in FIG. It won't get dirty when left over from a plastic bottle.

  The front frame 50 will be described. FIG. 9 is a perspective view of the front frame 50. The front frame 50 is composed of two substantially rectangular shaped frame bodies 52 in which a central portion of one side is cut out of four sides having a substantially rectangular shape. For example, the front frame 50 (frame body 52) has a diameter of 6 mm. The steel rod is bent into a substantially U shape, and the left and right ends are bent inward to form. The front frame 50 has upper and lower bent ends 52a on the support cylinder 35-2 (made of a steel pipe) of the front leg portion 32a2 of the side frame 30, as shown in FIG. 1 and FIG. It is inserted and connected to the side frame 30 and assembled. As can be seen from FIGS. 2 and 3A, since the garbage bag is mounted by hanging the garbage bag 12 on the shoulder portion 52b of the front frame 50, the length of the garbage bag 12 can be easily mounted. As described above, the size (length L3) of the front frame 50 is determined. In FIG. 7C, if the positional deviation between the support cylinder 35-1 for the back frame 40 and the support cylinder 35-2 for the front frame 50 is ΔL, the length L1 ( The relationship between the front frame length L3 and the front frame is indicated by L3 = L1 + ΔL.

The incorporation of each component will be described together with reference to FIG. Of course, the following assembly order is an example, and the present invention is not limited to this order.
1. Assembling of the side frame 30 A bent piece 33-1 behind the side frame 30 is inserted and connected to the horizontal frame 25-1 on the back surface (made of a steel pipe) of the bottom frame 20 placed at a predetermined position. At the same time, the front side horizontal frame 25-1 is inserted and connected with the bent piece 33-2 in front of the side frame 30 from the left and right, and the two side frames 30 (30 L, 30 R) are incorporated into the bottom frame 20. It is. Here, as described above, the folding angles of the folding pieces 33-1 and 33-2 are different (see FIGS. 7A and 7B), and their insertion directions do not match. Even if the front bent piece 33-2 is inserted after the piece 33-1 is inserted, the pushing force of the bent piece 33-2 is applied to the inserted bent piece 33-1. The side frame 30 can be easily inserted into the horizontal frame 25-1 without any action, and the bent pieces 33-1 and 33-2 can be easily inserted without detaching the inserted bent pieces. It is quickly and easily assembled into the bottom frame 20.

2. Assembling of the back frame 40 The back frame 40 has left and right side frames 30 (30L) by inserting and connecting the left and right ends 40a facing downward to the support cylinder 35-1 (made of steel pipe) on the back of the side frame 30. , 30R).

3. Assembling the Front Frame 50 The front frame 50 is assembled into the side frame 30 by inserting and connecting the upper and lower bent ends 52a thereof from above and below to the support cylinder 35-2 (made of steel pipe) of the side frame 30. By incorporating the front frame 50, the dust box 10 is assembled.
Here, as can be seen from FIG. 7C, the support cylinder 35-2 for the front frame 50 is located at a position shifted by θ4 (45 °) outward from the connecting portion 32b. The front frame 50 to be inserted into and connected to the support cylinder 35-2 that is shifted by 45 ° on the outside is connected to the front portion F, which is approximately 90 ° with respect to the connecting portion 32b that contacts the connecting portion 32b. It can be rotated within a range of θ3 (approximately 270 °) between the storage positions B substantially parallel to 32b. As described above, the rotation of the front frame 50 in the pushing direction (back frame direction) is restricted by contacting the connecting portion 32b. However, since there is a gap allowing rotation between the bent end 52a of the front frame 50 and the support cylinder 35-2, the front frame 50 is further pushed by Δθ3 from the front position F by an amount corresponding to the gap. It can be rotated to the position F ′ . When the front frame 50 is pushed into the position F ′ , an elastic force that attempts to return the front frame 50 in the front position F direction acts on the front frame.

  As described above, the dust box 10 is divided into the bottom frame 20, the two side frames 30, the back frame 40, and the front frame 50, and can be assembled and assembled. Therefore, the dust box 10 can be easily transported and stored. A product with excellent transportability is obtained. If there is a step in the upper surface positions of the two side frames 30, the rear frame 40, and the front frame 50, the dumped garbage causes a downward pulling force on the folded portion of the garbage bag 12, and the garbage bag is formed at the folded portion. Since they are easily damaged, the upper surface positions of the two side frames 30, the back frame 40, and the front frame 50 are substantially the same.

  Next, insertion of the garbage bag 12 will be described. The roll-shaped garbage bag 12 ′ is held on the shelf body 44 of the back frame 40, and the tip of the roll-shaped garbage bag is pulled up through the gap between the bent end 44 a ′ of the shelf body 44 and the frame body 46. In this case (see FIG. 3B), the single garbage bag 12 is broken and separated from the perforation by being locked to the projecting portion 46a of the frame 46. As shown in FIGS. 2 and 3, the garbage bag 12 separated from the roll-shaped garbage bag 12 ′ is folded at the upper end of the opening, and as can be seen from FIGS. 2 and 3, (1) shoulder portions 42a of the central bent portion 42 of the back frame 40, The upper end of the leg part 32a on the rear surface of the side frame 20 (strictly speaking, the connection point 33 between the leg part 32a and the connection part 32b (see FIG. 6)), (3) the upper end of the leg part 32a on the front surface of the side frame 20 ( Strictly speaking, it is attached to the dust box 10 by locking the folding edge at four points, that is, the support cylinder 35-2) of the side frame 20 and (4) the upper edge 52b of the front frame 50.

The combination of the locking points of (1) to (4) that lock the folding edge of the garbage bag 12 is formed in total, two on each side, so that two garbage bags can be mounted side by side, The dust box 10 can be used as a separate collection dust box.
However, (1) (4) is not locked, and (2) (3) the upper ends of the front and rear leg portions 32a of the side frame 20, the left and right upper ends of the four leg portions in total, the opening of the garbage bag. If the upper end fold is locked, one large garbage bag 12 is attached. For this reason, the dust box 10 is also used as a dedicated dust box equipped with one large garbage bag 12 for a large amount of specific garbage, and a highly versatile one that can be used in both separate collection and normal collection is obtained. And even when used as a dust box for normal collection, because the back frame 40 and the frame body 52 of the front frame 50 formed with the shoulder 42a used for wearing garbage bags at the time of separate collection are not removed, Never lose them. For example, as the garbage bag 12, a 45-liter garbage bag is used for the separate collection, and a 70-liter garbage bag is used for the normal collection.

  Here, although the rotation of the front frame 50 in the pushing direction (back frame direction) is restricted by the contact with the connecting portion 32b of the side frame 30, the front frame 50 is pushed down to the position F ′. If it rotates, a margin will arise and the garbage bag 12 will be easily latched by the four points of said (1)-(4), and mounting | wearing can be performed easily and rapidly. Since the elastic force to return to the front position F direction acts on the front frame 50 pushed into the position F ′, the elastic force is applied to the front frame by removing the pushing force of the front frame after the garbage bag 12 is attached. The frame is pressed against the garbage bag, and the garbage bag is mounted under the elastic force. For this reason, the garbage bag 12 is not attached and hangs down so that the upper end opening of the garbage bag 12 is blocked and the dumping of garbage is not obstructed.

  Since the garbage bag 12 is supported on the support surface 22 (see FIG. 3A) of the frame body 20, it is isolated from the tray even if the tray 29 is disposed below the bottom frame. For this reason, the garbage bag 12 does not enter the tray 29 and is immersed in the leftover of the tray, and the surroundings are not contaminated when the garbage bag 12 is collected.

  The garbage bag 12 is collected by using the front surface which is the only open end of the left, right and front. First, the release will be described. As in the case of mounting, the front frame 50 is pushed in and rotated to the position F ′, and the upper end of the garbage bag is folded at the portion that engages with the shoulder 52b of the front frame 50. Is raised, the locking by the front frame is released, and the garbage bag is released from the mounted state in the front frame. If the lock is released at one of the four points, the lock at the other three points is also released naturally, and the garbage bag 12 is released from the mounted state. When the garbage bag 12 is pulled forward, the garbage bag is pulled out from the dust box 10 and collected while rotating the front frame 50 in the position B direction to escape outward.

  Here, since the side wall 34 is formed in the side frame 30, even if a plastic bottle etc. is thrown away and accumulates irregularly, it is obstructed by the side wall and the garbage bag does not bulge greatly to the side. Further, since the front surface is open, the weight of the stacked PET bottles and the like escapes toward the open front surface, and the lower half of the garbage bag is not strongly pressed against the side wall 34. Therefore, even if the garbage bag 12 is pulled forward for collection, a large frictional force is not generated between the bulging portion of the garbage bag and the side wall 34, and the garbage bag is broken by rubbing with the side frame 30. It never happens. Therefore, it is possible to avoid a situation in which a leftover remaining in the bottom of the garbage bag is suddenly ejected from the broken hole, and the garbage bag 12 can be collected without contaminating the surroundings.

  The above-described embodiments are for explaining the present invention, and the present invention is not limited to the above-mentioned embodiments and modifications, and other modifications and modifications other than those described above are within the scope of the present invention. Needless to say, this is possible.

  In the embodiment, the front frame 50 (frame body 52) is formed by cutting one side of four sides of a substantially rectangular shape and locking the upper and lower ends of the front frame 50 to the support cylinder 35-2 from above and below. 30. However, the configuration is not limited to the configuration of the embodiment (see FIG. 10A), and the front frame 50 is formed in a cantilever shape in which the front frame 50 is substantially L-shaped and only its upper end is locked to the support cylinder 35-2. You may attach to the side frame 30 so that rotation is possible (refer FIG. 10 (B)). However, in the cantilever-shaped front frame 50 (frame body 52), there is a possibility that the garbage bag 12 may be caught by the free end and damaged. In the front frame 50, the front frame 50 is not easily detached from the side frame 30 and has a closed loop shape, so that there is no possibility of the garbage bag being caught.

  Furthermore, although the back frame 40 and the front frame 50 are locked to the side frame 30 using the support cylinders 35-1 and 35-2, the locking means is not limited to the support cylinder. Two L-shaped members with holes may be provided apart in the vertical direction, and the ends of the back frame 40 and the front frame 50 may be inserted into the locking holes. However, according to the support cylinder of the embodiment, the locking length can be increased and the back frame 40 and the front frame 50 can be reliably connected.

  The dust box of the present invention can be used as it is, for example, a dumping hole is formed on the upper surface, a double door or one hinged door is formed on the front surface, and can be stored and used in a dust case with a bottom. It can be used widely as a dust box in places (open spaces), homes, offices, etc.
