Description

[Technical Field]

[0001] The present invention relates to a dustpan having a dust collection case for collecting dirt and dust and a rod-shaped grip handle. [Background technology]

[0002] BACKGROUND ART Conventionally, there has been known a dustpan for home use that is provided with a plastic dust collection case for collecting dirt and dust (Patent Document 1).

[0003] The dustpan described in Patent Document 1 has one of its side panels curved in a horizontal U-shape, which solves the problem that conventional dustpans have, where if the opening (discharge outlet) of the dustpan is larger than the opening of the trash can, some of the dust that has been carefully collected will fall out of the trash can. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Japanese Utility Model Application Publication No. 1875-1973 Summary of the Invention [Problem to be solved by the invention]

[0005] However, the dustpan described in Patent Document 1 has a problem in that one of the side panels is curved in a horizontal U-shape, which means that the collected dust overlaps on the curved U-shape, making it difficult to discharge the dust smoothly.

[0006] To solve the above-mentioned conventional problems, and an object of the present invention is to provide a dustpan that can prevent part of the collected dust from spilling out of a trash can when discharging the dust, and can discharge the dust smoothly. [Means for solving the problem]

[0007] In order to solve the above-mentioned conventional problems, the invention of claim 1 is a dustpan consisting of a roughly rod-shaped handle, a dustpan provided at the lower end of the handle, a roughly flat bottom plate, and side plates rising from both side ends and the rear end of the bottom plate, wherein the inner surface of at least one of the side plates rising from both side ends of the bottom plate is integrally formed with a discharge surface formed to be a plane roughly perpendicular to the bottom plate of the dust collection case, and two guide surfaces that share two opposing sides extending in the discharge direction of the discharge surface with the discharge surface and are each inclined from both sides of the two sides toward the discharge surface, and wherein the two guide surfaces have an inclination angle with respect to the discharge surface of 20 degrees or less.

[0008] The dustpan invention of claim 1 can discharge trash from the side panel of the dust collection case, preventing some of the trash and dust from spilling out of the trash can. Also, since guide surfaces are formed on both sides of the discharge surface that are inclined toward the discharge surface, trash and dust can be directed toward the discharge surface and prevented from spilling out and scattering. Furthermore, since the discharge surface is flat, it is possible to prevent trash from piling up compared to a curved surface, and trash can be discharged more smoothly.

[0009] The invention of claim 2 is a dustpan comprising a generally rod-shaped handle, a dustpan provided at the lower end of the handle and having a generally flat bottom plate and side plates rising from both side edges and a rear end of the bottom plate, wherein the inner surface of at least one of the side plates rising from both side edges of the bottom plate is integrally formed with a discharge surface formed to be a plane generally perpendicular to the bottom plate of the dustpan, and two guide surfaces that share two opposing sides extending in the discharge direction of the discharge surface with the discharge surface and are inclined from both sides of the two sides toward the discharge surface, the two guide surfaces being formed so as to gradually widen toward the front side of the dustpan. During discharge, dust in the dustpan is forcefully transported to the front end of the discharge surface, but by making the guide surfaces wider, it is possible to prevent the dust from spilling out from the sides and to guide it toward the discharge surface.

[0010] The invention of claim 3 is characterized in that, in the invention of claim 1 or 2, the discharge surface is formed so as to gradually narrow toward the front side of the dust collection case. This makes it possible to accurately transport the waste to the trash bin without scattering it further when it is discharged. In addition, because the rear side of the discharge surface is wider, it is possible to prevent the waste from overflowing while ensuring the amount of dust collected.

[0011] The invention of claim 4 is characterized in that, in any of the inventions of claims 1 to 3, a rear guide surface inclined toward the discharge surface is formed at the rear end of the discharge surface. This allows waste to be smoothly transported to the front side of the discharge surface during discharge, reducing the amount of waste left behind and allowing waste to be discharged efficiently.

[0012] The invention of claim 5 is characterized in that in any of the inventions of claims 1 to 4, the discharge surface and the guide surface are formed on the inner surfaces of the side plates that stand up from both ends of the bottom plate. Therefore, regardless of dominant hand, it is easier to discharge waste with either the left or right hand.

[0013] The invention of claim 6 is characterized in that, in the invention of any one of claims 1 to 5, the ejection surface is formed of conductive resin, which makes it possible to suppress charging of the ejection surface and to smoothly eject dirt and dust from the ejection surface.

[0014] The invention of claim 7 is characterized in that, in the invention of any one of claims 1 to 6, a soft member is disposed at the front end of the bottom plate of the dust-collecting case, and the discharge surface has a smaller friction resistance than the soft member. Therefore, it is possible to suppress the discharge of dust from the front of the bottom plate of the dust-collecting case, and to discharge the dust smoothly from the discharge surface.

[0015] The invention of claim 8 is characterized in that, in any one of the inventions of claims 1 to 7, the longitudinal direction of the discharge surface is formed to be approximately perpendicular to the longitudinal direction of the handle. Therefore, by rotating the handle about the axis from a state in which the discharge surface is parallel to the floor surface, the front end of the discharge surface can be easily tilted downward, improving operability and making it easier to discharge waste.

[0016] The invention of claim 9 is characterized in that, in the invention of claim 8, the center of gravity of the dust collection case is located forward of the connection between the dust collection case and the handle. Therefore, the discharge surface is easily tilted downward from a state parallel to the floor surface, with the front end of the discharge surface tilting downward around the axis of the handle, improving operability and making it easier to discharge dust. [Effects of the Invention]

[0017] The dustpan invention of claim 1 can prevent some of the trash and dust from spilling out of the trash can. It can also direct the trash and dust toward the discharge surface. It can also prevent trash from piling up, allowing trash to be discharged smoothly. The invention of claim 2 can prevent trash from spilling out the sides and guide it toward the discharge surface. The invention of claim 3 can accurately transport trash to the trash can when discharging without scattering it further. It can also prevent trash from overflowing while ensuring the amount of dust collected. The invention of claim 4 can prevent trash from being left behind, allowing trash to be discharged efficiently.

[0018] The invention of claim 5 allows users to more easily discharge trash with either their left or right hand, regardless of their dominant hand. The invention of claim 6 also prevents static electricity from building up on the discharge surface, allowing trash and dust to be discharged smoothly from the discharge surface.

[0019] The invention of claim 7 can suppress the discharge of dust from the front of the bottom plate of the dust collection case and can discharge dust smoothly from the discharge surface. Furthermore, the inventions of claims 8 and 9 can improve operability and make it easy to discharge dust. [Brief explanation of the drawings]

DETAILED DESCRIPTION OF THE INVENTION

[0021] Hereinafter, embodiments of the present invention will be described with reference to the drawings. However, the present invention is not limited to these embodiments. Fig. 1(a) is a perspective view of a dustpan according to the present invention in a dust collection mode, Fig. 1(b) is a front view of the dustpan according to the present invention in the dust collection mode, and Fig. 1(c) is a left side view of the dustpan according to the present invention in the dust collection mode. Fig. 1(d) is a longitudinal cross-sectional view of the dustpan according to the present invention in the dust collection mode, and Fig. 1(e) is a partial cross-sectional view of the dustpan according to the present invention in the dust collection mode. Fig. 2(a) is a perspective view of a dustpan according to the present invention in a storage mode, Fig. 2(b) is a perspective view of the dustpan according to the present invention combined with a broom in the storage mode, and Fig. 2(c) is a left side view of the dustpan according to the present invention combined with a broom and placed against a wall in the storage mode. An overview of the dustpan according to the present invention will be described below using these figures.

[0022] The dustpan 10 according to the present invention comprises a generally rod-shaped handle 1, a dust collection case 2 provided at the lower end of the handle 1 and having a generally flat bottom plate 21, side plates 22 rising from both side edges and the rear end of the bottom plate 21, and a top plate 23 extending from the side plates 22 so as to cover the upper rear of the bottom plate 21, and a pivoting means 3 (connecting portion) pivotally connecting the end of the handle 1 to the top plate 23 of the dust collection case 2. The bottom plate 21 of the dust collection case 2 has a soft member 6 at its front end. A handle 1a is formed at the end of the handle 1, and a locking holder 12 is attached near the handle 1a. This locking holder 12 can lock a broom handle 8a, as will be described later. In addition, the present invention also includes a configuration that does not have a top plate 23 and a rotating means 3, and in which the lower end of the grip handle 1 is fixed to the bottom plate 21, or a configuration in which the lower end of the grip handle 1 is fixed to a side plate 22 that stands up from the rear end of the bottom plate 21.

[0023] At least one of the inner surfaces of the side plates 22, 22 rising from both ends of the bottom plate 21 is integrally formed with a discharge surface 22d formed as a plane substantially perpendicular to the bottom plate of the dust collection case, and guide surfaces 22e, 22e inclined from both sides of the discharge surface 22d toward the discharge surface 22d. This allows dirt and dust to be drawn toward the discharge surface and prevents them from spilling and scattering. Furthermore, because the discharge surface is flat, pile-up of dirt can be suppressed compared to a curved surface, allowing for smooth discharge of dirt. Note that the discharge surface and guide surfaces may be formed on either inner surface of the side plates rising from both ends of the bottom plate, and this is also within the scope of the present invention.

[0024] Discharge surface 22d is formed so as to gradually narrow toward the front side of dust collection case 2. Furthermore, guide surface 22e is formed so as to gradually widen toward the front side of dust collection case 2. Furthermore, rear guide surface 22f is formed at the rear end of discharge surface 22d, and is inclined toward discharge surface 22d.

[0025] The discharge surface 22d is preferably formed from a conductive resin. This can prevent the discharge surface from becoming electrically charged, allowing dirt and dust to be smoothly discharged from the discharge surface. Furthermore, if the guide surfaces 22e, 22e, and the bottom plate 21 are formed from a conductive resin, the dirt and dust contained inside the dust-collecting case 2 can be more smoothly guided to the discharge surface 22d, and the dirt and dust can be prevented from remaining inside the dust-collecting case 2. Furthermore, the discharge surface 22d preferably has a lower friction resistance than the soft member 6. This can prevent dirt from being discharged from the front of the bottom plate 21 of the dust-collecting case 2, and allows the dirt to be smoothly discharged from the discharge surface 22d.

[0026] The dust collection case 2 has a lower opening 4 formed by a bottom plate 21 and a part of the side plate 22, and an upper opening 5 formed by a top plate 23 and a part of the side plate 22. Here, an imaginary line 7 connecting corners 22a, 22a located at the front upper part of the side plate shown in FIG. 1(a) is a boundary line between the lower opening 4 and the upper opening 5. The lower opening 4 is defined by the area surrounded by the imaginary line 7, the edges 22b of the side panels, and the edge 6a of the soft member. The upper opening 5 is defined by the area surrounded by the imaginary line 7, the upper edges 22c of the side panels, and the edge 23a of the top panel.

[0027] The dustpan 10 can be transformed into a storage mode in which the lower opening 4 of the dust collection case 2 faces downward and can rest against the floor with the handle 1 held upright in a direction substantially perpendicular to the floor, and into a dust collection mode in which the bottom plate 21 of the dust collection case 2 faces downward and can rest against the floor. The dust collection case 2 is integrally formed from a synthetic resin, and polypropylene, conductive polypropylene, ABS resin, conductive ABS resin, polyamide resin, etc. can be used. The soft member 6 is preferably made of rubber.

[0028] In the storage mode, the dustpan 10 is configured so that the soft member 6 does not abut on the floor surface, thereby suppressing deterioration of the soft member 6 and improving durability.

[0029] The dustpan 10 has a recess formed on the outer surface of the dust collection case top panel 23 that can accommodate part of the handle of the broom 8. As shown in FIG. 2(b), in storage mode, the broom 8 can be attached and detached, and has a handle 8a and a cleaning brush 11 attached to the bottom end of the handle 8a. One end of the cleaning brush 11 of the broom 8 is fixed to the base 9. Furthermore, a connecting portion 8c of the handle is connected to a connecting portion 9a of the base, and connecting portions 8c and 9a are equipped with a clutch mechanism, allowing the broom 8 to be fixed to the base 9 at any angle relative to the handle 8a. Reference numeral 8b denotes a handle formed at the end of the handle 8a.

[0030] 1(d), the rotating means 3 has a pressing member 13 biased by a spring 17 so as to protrude in the axial direction of the grip handle 1, a receiving member 14 formed on the outer surface of the top plate of the dust collection case and having two recesses 14a, 14b that fit with the pressing member 13, and an axial member 15 that connects the grip handle 1 so that it can rotate back and forth around the receiving member 14. Then, the grip handle 1 is locked when the protrusion 13a formed on the tip of the pressing member 13 fits into the recess 14a or 14b.

[0031] The locking holder 12 is formed of an elastic material with a substantially C-shaped cross section. Its inner diameter is approximately the same as the outer diameter of the locking ring 8d, and the opening diameter of the locking holder 12 is slightly shorter than the outer diameter of the locking ring 8d. The outer diameter of the broom handle 8b is also thicker than the outer diameter of the locking ring 8d. The outer diameter of the broom handle 8a is also thinner than the outer diameter of the locking ring 8d and shorter than the opening diameter of the locking holder 12. Therefore, when securing the broom 8 to the dustpan 10, the locking ring 8d can be secured to the locking holder 12 by inserting the broom handle 8a into the opening side of the locking holder 12 and then dropping it downward. However, the locking ring 8d can also be secured to the locking holder 12 by inserting it directly into the opening of the locking holder 12. The broom 8 can be easily removed from the dustpan 10 by performing the reverse of the steps used to secure the broom 8 to the dustpan 10.

[0032] 3(a) to 3(d) are left side views of the dustpan according to the present invention, showing the process of attaching and detaching the dustpan to and from the broom. Attaching and detaching the dustpan to and from the broom according to the present invention will be explained using these drawings.

[0033] First, as shown in FIG. 3(a), the broom 8 is separated from the dustpan 10, and the handle 1 is tilted counterclockwise by approximately 45 degrees, with the corner Z located at the lower front of the dustpan 10's side panel 22 as the fulcrum. Then, while maintaining the fulcrum at corner Z, the handle 1 is returned to a position perpendicular to the floor. While pushing the handle 1 downward, the rotation means 3 is unlocked, resulting in the state shown in FIG. 3(b). From this position, pushing the handle 1 further downward causes the bottom panel 21 of the dustpan 2 to abut against the floor, resulting in the dust collection mode state shown in FIG. 3(c). In this state, the rotation means 3 is locked, so the handle 1 remains approximately perpendicular to the floor.

[0034] On the other hand, to switch from the dust collection mode to the storage mode, from the state shown in FIG. 3(c), the broom 8 is pulled toward the dustpan 10, and the dustpan 10 tilts the handle 1 clockwise by approximately 45 degrees, using corner Z as a fulcrum. Then, while maintaining the corner fulcrum, the handle 1 is returned to a position perpendicular to the floor while pushing the handle 1 downward, unlocking the pivoting means 3 and resulting in the state shown in FIG. 3(d). From this state, the handle 1 of the dustpan 10 is brought closer to the broom handle 8a, engaging the locking ring 8d with the locking holder 12, thereby entering the storage mode state shown in FIG. 3(a). As described above, the user can switch between the storage mode and the dust collection mode by manipulating the handle 1. Since the user's hands do not come into contact with the dust collection case 2, this is hygienic and prevents the accumulation of dust and other particles.

[0035] Fig. 4(a) is a perspective view of a side plate constituting a dustpan according to the present invention, Fig. 4(b) is a front view of the same side plate, and Fig. 4(c) is a left side view of the same side plate. The dust-collection case is formed integrally, but for convenience of explanation, components other than the side plate are not shown. The side plate constituting the dustpan according to the present invention will be described below using these figures.

[0036] The side plate 22 is integrally formed with a discharge surface 22d, guide surfaces 22e, 22e inclined from both sides of the discharge surface 22d toward the discharge surface 22d, a rear guide surface 22f inclined toward the discharge surface 22d at the rear end of the discharge surface 22d, and top surfaces 22g, 22g at one side end of the guide surface 22e and the rear guide surface 22f. The length a of the front end of the discharge surface is shorter than the length d of the rear end of the discharge surface, and the width gradually narrows toward the front of the dust collection case. This allows the waste to be accurately transported to the trash can without scattering during discharge. Furthermore, the rear side of the discharge surface is wider, which prevents the waste from overflowing while ensuring a sufficient dust collection capacity.

[0037] Furthermore, guide surfaces 22e, 22e are formed so that the lengths b and c of the front ends of the guide surfaces are at their maximums and gradually widen toward the front of the dust collection case. This prevents dust from spilling out the sides and guides it toward the discharge surface. Furthermore, the length d of the front end of the rear guide surface is longer than the length e of the rear end of the rear guide surface, and the guide surfaces are formed so that the width gradually widens toward the rear end of the discharge surface. This allows dust to be smoothly transported to the front of the discharge surface during discharge, reducing the amount of dust left behind and enabling efficient waste discharge.

[0038] Incidentally, it is preferable that the inclination angles α and β between the discharge surface 22d and the guide surface 22e, and the inclination angle γ between the rear guide surface 22f and the discharge surface 22d are each formed in the range of 5 degrees to 20 degrees.

[0039] 5(a) is a left side view of the dustpan according to the present invention, showing the state in which dust is being discharged into a trash can. As shown in this figure, the longitudinal direction of the discharge surface 22d of the side panel 22 is formed to be approximately perpendicular to the longitudinal direction of the handle 1.

[0040] 5(b) is a perspective view of the dustpan according to the present invention, showing the state in which dust is being discharged into the trash can. As shown in this figure, the center of gravity 2a of the dust collection case 2 is located forward of the connection 3 between the dust collection case 2 and the handle 1. This allows the front end of the discharge surface 22d to easily tilt downward from a state parallel to the floor surface around the axis of the handle 1, improving operability and making it easier to discharge dust into the trash can 18. [Industrial Applicability]

[0041] The dustpan according to the present invention is used as a cleaning tool for collecting dirt and dust. [Explanation of symbols]
