[Modes for carrying out the invention]
[0012] (First Embodiment) The dustpan 10 according to the first embodiment of the present invention will be described with reference to Figures 1 to 3. The arrows FR, UP, RH, and LH in the figures indicate the front, up, right, and left directions of the dustpan 10, respectively. When simply referring to the front / back, up / down, and left / right directions in the following description, these directions refer to the front / back, up / down, and left / right directions of the dustpan 10.
[0013] As shown in Figure 1, the dustpan 10 of this embodiment comprises a dustpan body 12 that collects debris from an object to be cleaned (for example, the ground or the floor inside a building) swept by a broom or the like (not shown), and a handle 14 fixed to the dustpan body 12.
[0014] The dust collection main body 12 includes a bottom wall portion 16 that extends in the front-rear direction and the left-right direction with the vertical direction as the thickness direction, a rear wall portion 18 that rises upward from the rear end of the bottom wall portion 16, and a pair of left and right side wall portions 20 that rise upward from both ends of the bottom wall portion 16 in the left-right direction. Both ends of the rear wall portion 18 in the left-right direction are connected to the rear ends of the pair of left and right side wall portions 20. Further, the dust collection main body 12 includes a rear side flange portion 22 that extends rearward from the upper end of the rear wall portion 18 and has an end on the side opposite to the rear wall portion 18 bent downward. Further, the dust collection main body 12 includes a pair of left and right side flange portions 24 that extend from the upper ends of the pair of left and right side wall portions 20 toward the left and right respectively and have an end on the side opposite to the side wall portion 20 bent downward. Both ends of the rear side flange portion 22 in the left-right direction are connected to the rear ends of the pair of left and right side flange portions 24.
[0015] The handle 14 of the present embodiment is formed in a rod shape. One end of this handle 14 is fixed to the central portion in the left-right direction of the rear side flange portion 22 in the dust collection main body 12. Thereby, the handle 14 is configured to extend upward from the central portion in the left-right direction of the rear side flange portion 22 in the dust collection main body 12.
[0016] Next, the configuration of the main part of the present embodiment will be described.
[0017] As shown in FIGS. 1, 2, and 3, a dust passage hole 26 that penetrates the rear wall portion 18 in the front-rear direction is formed in the right side portion of the rear wall portion 18 of the dust collection main body 12. The edge of this dust passage hole 26 is circular when viewed from the front side. Note that the shape of the edge of the dust passage hole 26 when viewed from the front side is not limited to a circle. For example, the shape of the edge of the dust passage hole 26 when viewed from the front side may be other shapes such as a square shape or an elliptical shape. The shape and size of the dust passage hole 26 may be appropriately set in consideration of the type (shape and size) of dust collected in the dust collection main body 12.
[0018] On the rear side of the rear wall portion 18 of the dust collection main body portion 12, a bag attachment portion 28 formed in a cylindrical shape is provided. The bag attachment portion 28 of the present embodiment is formed in a cylindrical shape with the front-rear direction as the axial direction. Further, the front end portion of the bag attachment portion 28 is connected to the rear wall portion 18 at a position communicating with the dust passage hole 26. Thereby, the bag attachment portion 28 is configured to protrude rearward from the rear wall portion 18. Note that the bag attachment portion 28 and the dust collection main body portion 12 may be integrally formed, or may be formed separately and then connected.
[0019] Here, the inner diameter of the bag attachment portion 28 may be set to be larger than the inner diameter of the dust passage hole 26. Also, the inner diameter of the bag attachment portion 28 may be set to be smaller than the inner diameter of the dust passage hole 26. Furthermore, the inner diameter of the bag attachment portion 28 may be set to be the same as the inner diameter of the dust passage hole 26.
[0020] As shown in FIGS. 2 and 3, on the rear side of the rear wall portion 18 of the dust collection main body portion 12, a stopper member locking portion 30 is provided. The stopper member locking portion 30 of the present embodiment includes a stopper member locking portion main body 32 formed in a columnar shape with the front-rear direction as the axial direction, and a catching portion 34 protruding from the rear end portion of the stopper member locking portion main body 32 toward the right side (opposite side to the bag attachment portion 28). The front end portion of the stopper member locking portion main body 32 is connected to the rear wall portion 18 at a position adjacent to the bag attachment portion 28 (on the right side with respect to the bag attachment portion 28 in the present embodiment). Thereby, the stopper member locking portion 30 is configured to protrude rearward from the rear wall portion 18. Note that the stopper member locking portion 30 and the dust collection main body portion 12 may be integrally formed, or may be formed separately and then connected.
[0021] (Operations and Effects of the Present Embodiment) Next, the operations and effects of the present embodiment will be described.
[0022] As shown in Figures 1, 2, and 3, in the dustpan 10 of this embodiment, a bag 36 such as a plastic bag can be attached to the bag attachment portion 28. For example, after placing the open end 36A of the bag 36 over the outer circumferential surface of the bag attachment portion 28, a ring-shaped fastening member 38 made of rubber or the like is wrapped around the bag attachment portion 28. This ensures that the open end 36A of the bag 36 is secured to the outer circumferential surface of the bag attachment portion 28 by the fastening member 38. In this embodiment, a fastening member locking portion 30 capable of locking the fastening member 38 is provided adjacent to the bag attachment portion 28. Therefore, for example, after locking a part of the fastening member 38 to the fastening member locking portion 30, the fastening member 38 can be stretched and wrapped around the bag attachment portion 28 to lock another part of the fastening member 38 to the fastening member locking portion 30. This makes it easy to secure the open end 36A of the bag 36 to the outer circumferential surface of the bag attachment portion 28 with the fastening member 38. Furthermore, because the locking portion 30 of the stopper member has a hooking portion 34, it is prevented from the stopper member 38, which is locked to the locking portion 30, coming off the locking portion 30.
[0023] As described above, in the dustpan 10 of this embodiment, the bag 36 can be attached to the bag attachment part 28. Furthermore, in the dustpan 10 of this embodiment, the dust collected in the dustpan body 12 can be moved into the bag 36 through the dust passage hole 26 and the inner circumference of the bag attachment part 28. Thus, in the dustpan 10 of this embodiment, the dust collected in the dustpan body 12 can be moved directly into the bag 36.
[0024] (Second Embodiment) The dustpan 40 according to the second embodiment of the present invention will be described with reference to Figures 4 and 5. In the dustpan 40 according to the second embodiment, the members and parts corresponding to the dustpan 10 of the first embodiment described above will be denoted by the same reference numerals as the members and parts corresponding to the dustpan 10 of the first embodiment, and their descriptions may be omitted.
[0025] As shown in Figures 4 and 5, the dustpan 40 of this embodiment is equipped with a fastening member 42 that is detachably attached to the outer circumferential side (outer surface) of the bag attachment portion 28.
[0026] As shown in Figure 4, the stopper member 42 comprises a first stopper portion 44 and a second stopper portion 46 formed integrally with the first stopper portion 44. The first stopper portion 44 and the second stopper portion 46 are each formed in the shape of a rectangular block. The portions of the first stopper portion 44 and the second stopper portion 46 on one longitudinal side are connected via an integral hinge portion 48. The integral hinge portion 48 is bendable, which allows the first stopper portion 44 to be displaced relative to the second stopper portion 46. On the other longitudinal side of the second stopper portion 46, there is a locking portion 50 that protrudes from the second stopper portion 46. On the other longitudinal side of the first stopper portion 44, there is a tongue-shaped locking portion 52 that extends from the first stopper portion 44 side toward the second stopper portion 46 side. This locking portion 52 has an opening into which the locking portion 50 can be placed. The locking portion 52 is locked to the locked portion 50, thereby limiting the displacement of the first stopper portion 44 relative to the second stopper portion 46. Here, the state in which the stopper member 42 is locked to the locked portion 52 will be referred to as the "closed state of the stopper member 42." The state in which the stopper member 42 is unable to lock to the locked portion 50 will be referred to as the "open state of the stopper member 42." The first stopper portion 44 has a recess 54 formed therein, which is open on the side of the second stopper portion 46. The inner surface of this recess 54 is semi-cylindrical. The second stopper portion 46 has a recess 54 formed therein, which is open on the side of the first stopper portion 44. The inner surface of this recess 54 is semi-cylindrical. As shown in Figures 4 and 5, when the stopper member 42 is closed, the recess 54 of the first stopper portion 44 and the recess 54 of the second stopper portion 46 can cover the outer circumferential surface of the bag attachment portion 28. Here, when the fastening member 42 is closed, the inner diameters of the recesses 54 of the first fastening portion 44 and the second fastening portion 46 are larger than the outer diameter of the bag attachment portion 28. The first fastening portion 44 and the second fastening portion 46 are provided with a plurality of elastically deformable portions 56 that protrude from the inner circumferential surface of the recess 54. Each of the plurality of elastically deformable portions 56 is formed in a pleated shape that extends along the axial direction of the inner circumferential surface of the recess 54 and is arranged at intervals along the circumferential direction of the inner circumferential surface of the recess 54.
[0027] In the dustpan 40 of this embodiment described above, a bag 36 (see Figure 2), such as a plastic bag, can be attached to the bag attachment portion 28 via a fastening member 42. For example, after placing the open end 36A of the bag 36 over the outer circumferential surface of the bag attachment portion 28, the open fastening member 42 is positioned on the outer circumferential side of the bag attachment portion 28. Then, by closing the open fastening member 42 (locking the locking portion 52 to the locking portion 50), the open end 36A of the bag 36 is sandwiched between the bag attachment portion 28 and the fastening member 42. This maintains the state in which the bag 36 is attached to the bag attachment portion 28. In this embodiment, a plurality of elastically deformable portions 56 are provided. These elastically deformable portions 56 come into contact with the bag 36 and elastically deform relative to the bag attachment portion 28 when closing the open fastening member 42. Due to the restoring force associated with the elastic deformation of these elastically deformable portions 56, the open end 36A of the bag 36 is pressed against the outer circumferential surface of the bag attachment portion 28. As a result, the bag 36 remains attached to the bag attachment part 28.
[0028] As described above, in the dustpan 40 of this embodiment, the bag 36 can be attached to the bag attachment portion 28. Furthermore, in the dustpan 40 of this embodiment, the dust collected in the dustpan body portion 12 can be moved into the bag 36 through the dust passage hole 26 and the inner circumference of the bag attachment portion 28. Thus, in the dustpan 40 of this embodiment, the dust collected in the dustpan body portion 12 can be moved directly into the bag 36.
[0029] In this embodiment, an example of a dustpan 40 with multiple elastic deformation parts 56 has been described, but the present invention is not limited to this. For example, a stopper member with a configuration that omits the multiple elastic deformation parts 56 can also be used.
[0030] (Summary of the effects of the dustpan 10 in the first embodiment and the dustpan 40 in the second embodiment) The dustpans 10 and 40 according to the present invention, as described above, can eliminate the problems of conventional dustpans, such as "the hassle of transferring collected waste to another container" and "the problem of waste scattering during transfer." Conventional dustpans required tilting the dustpan to transfer the waste accumulated on the bottom wall into a separately prepared garbage bag or trash can, but in this case, there was a risk that fine dust would be scattered again into the surroundings due to wind or unstable operation. In addition, it was necessary for the worker to bend over or assist manually, which increased the workload and raised hygiene issues.
[0031] In contrast, the dustpans 10 and 40 of this embodiment are equipped with a waste passage hole 26 formed in the dustpan body 12 and a bag attachment part 28 communicating therewith, making it possible to perform a series of operations from waste collection to disposal continuously and efficiently. That is, the waste swept up with a broom or the like accumulates on the bottom wall 16, and then, with appropriate operation, is guided through the waste passage hole 26 to the bag attachment part 28 and stored directly inside the bag 36. This configuration eliminates the need for a waste transfer process, improving work efficiency and the hygiene of the cleaning environment.
[0032] Furthermore, the configuration in which the bag attachment portion 28 protrudes from the rear side of the rear wall portion 18 is advantageous in terms of visibility and operability during operation. In other words, when an operator collects dust from the front of the dustpan body portion 12, they can perform the same operation as a normal dustpan without being aware of the presence of the bag, while the collected dust is naturally guided to the bag at the rear, so the flow of work is not interrupted. In addition, because the bag 36 is positioned at the rear, the direction in which the dust falls and the direction in which the bag opens coincide, enabling smooth movement of the dust using gravity.
[0033] The configuration of the retaining member locking portion 30 in the first embodiment plays an important role in making the bag 36 attachment work easy and reliable. In particular, the presence of the hooking portion 34 prevents the retaining member 38 from coming off unintentionally, and has the effect of suppressing the bag 36 from falling off. This prevents the problem of the bag 36 coming off during work and scattering garbage. In addition, since the retaining member 38 can be wrapped around the retaining member locking portion 30 while partially fixed, there is also the advantage that the bag 36 can be attached relatively easily with one hand.
[0034] On the other hand, the fastening member 42 adopted in the second embodiment has a configuration that takes into consideration more reliable fixing force and reusability. The first fastening part 44 and the second fastening part 46, which can be opened and closed via the integral hinge part 48, can be easily opened and closed without the use of tools and are suitable for repeated use. In addition, the locking mechanism of the locking part 52 and the locked part 50 can stably maintain the closed state.
[0035] Furthermore, the provision of multiple elastically deformable portions 56 is one of the distinctive features of this invention. These elastically deformable portions 56 play a role in uniformly applying pressure to the outer surface of the bag attachment portion 28 and the open end side 36A of the bag 36. This ensures stable holding force even if there are variations in the material and thickness of the bag 36. In addition, because the elastically deformable portions 56 are formed in a pleated shape, localized stress concentration is mitigated, which is expected to prevent tearing and damage to the bag.
[0036] As described above, the dustpans 10 and 40 according to this invention integrate the entire process from waste collection to disposal, exhibiting excellent effects in terms of work efficiency, hygiene, and safety. Furthermore, the structure itself is relatively simple and can be easily implemented using existing manufacturing technologies, making it cost-effective and highly practical, applicable to a wide range of uses from household to commercial.
[0037] Furthermore, the dustpan of this invention is not limited to the embodiments described above, and various modifications can be made without departing from the spirit of this invention. For example, as shown in Figures 6(A) and (B), the dust passage hole 26 and the bag attachment portion 28 may be provided in the center of the rear wall portion 18 of the dustpan body portion 12 in the left-right direction, or on the left side. Also, as shown in Figures 7(A) and (B), one end of the handle 14 may be fixed to the right side or to the left side of the rear flange portion 22 of the dustpan body portion 12.
