Description
[Technical Field]
[0001] The present invention relates to a broom with a dustpan that can be stored in a state where the broom and the dustpan are connected to each other. [Background technology]
[0002] BACKGROUND ART Conventionally, brooms with attached dustpans that can be detachably attached to the broom and stored when not in use have been widely known, as described in Patent Document 1, for example. However, in this type of broom with a dustpan, the dustpan cannot stand on its own, so when storing it, it is necessary to lean the broom with the dustpan attached against a wall, etc. Therefore, the broom with a dustpan described in Patent Document 2 is equipped with a magnet, making it possible to attach and detach it to a magnetic wall, for example, around an entrance, thereby improving storage ease when not in use.
[0003] However, in the broom with dustpan described in Patent Document 2, if the engagement force of the dustpan with the broom decreases due to aging or other reasons, the dustpan may easily separate and fall off the broom, which is attached to the wall surface by the magnet, and the convenience of the broom with dustpan may be reduced. [Prior art documents] [Patent documents]
[0004] [Patent Document 1] CD-ROM of Utility Model Application No. 4-80370 (Utility Model Application No. 6-36427) [Patent Document 2] Japanese Patent Application Publication No. 2020-36720 Summary of the Invention [Problem to be solved by the invention]
[0005] To provide a broom with a dustpan that can be attached detachably to a wall surface made of a magnetic material by a magnet while the broom and dustpan are combined, and to prevent the dustpan and the broom from separating from each other when the broom is stored attached to the wall surface. [Means for solving the problem]
[0006] In order to solve the above problems, the broom with dustpan according to the present invention comprises a broom having a flattened wiping body attached to the tip of a rod-shaped handle extending in the axial direction, a handle having a recessed portion that opens to the front side and can accommodate the tip of the handle, and a dustpan connected to the tip of the handle and having a sweeping portion that is recessed and opens to the front side and can accommodate the wiping body, and when not in use, the tip of the handle and the wiping body of the broom can be stored in a mutually coupled state by storing the tip of the handle and the wiping body in the recessed portion of the handle and the sweeping portion of the dustpan, respectively, and the wiping body of the broom is attached to the tip of a rod-shaped handle that extends in the axial direction, and the dustpan has a flattened holder portion connected to the handle and a dustpan that is recessed and can accommodate the wiping body of the holder. The broom has a brush head, one end of which is held inside the holder and the other end of which extends outside the holder, and the holder has an engagement hole that penetrates from the first surface to the second surface in the thickness direction of the holder, and the sweeping part of the dustpan has a bottom surface facing the front side and an engagement protrusion that protrudes from the bottom surface and is inserted and removed into the engagement hole of the holder, and the top surface of the engagement protrusion is formed by a magnetic attraction surface, and when the broom and dustpan are connected to each other and the engagement protrusion of the sweeping part is engaged with the engagement hole of the holder from the first surface side toward the second surface side, the top surface of the engagement protrusion is on the same plane as the second surface of the holder or protrudes further than the second surface of the holder.
[0007] In the present invention, it is preferable that the sweeping part of the dustpan has a sweeping opening formed by the tip edge of the bottom surface at the tip end opposite the handle.
[0008] The sweeping portion of the dustpan may further have a pair of side surfaces extending from both widthwise ends of the bottom surface, and the top surfaces of the engaging projections may be on a plane that includes the leading edges of the pair of side surfaces in the height direction and is parallel to the axis, or may protrude beyond that plane. In this case, the top surfaces of the engaging projections may be parallel to the plane, or the opening edge of the recess in the handle of the dustpan may be on the plane.
[0009] In the present invention, it is preferable that the recess in the handle of the dustpan be provided with a locking portion that locks the handle into the recess when the tip of the handle of the broom is housed therein.
[0010] Furthermore, when the broom and the dustpan are combined, it is preferable that the shape of the engagement hole of the broom and the shape of the engagement protrusion of the dustpan are symmetrical in the width direction with respect to the axis. [Effects of the Invention]
[0011] According to the present invention, in a broom with a dustpan that can be attached and detached freely to a wall surface made of a magnetic material using a magnet when the broom and dustpan are combined, the dustpan's engaging protrusion is configured so that when the dustpan's engaging protrusion is fitted into the broom's engaging hole, the top surface of the engaging protrusion made of a magnet can be attracted to the wall surface, making it possible to prevent the dustpan and broom from separating from each other when attached to the wall for storage.

[0013] A broom with a dustpan according to one embodiment of the present invention will be described below with reference to Figures 1 to 16. The broom with a dustpan 1 has a sweeping broom 2 and a dustpan 3 for collecting dust to which the broom 2 is detachably connected. When cleaning, the broom 2 and the dustpan 3 are used separately, and when not in use, the broom 2 is attached to the dustpan 3 and the two are stored together.
[0014] As shown in Figures 1 to 4, broom with dustpan 1 comprises a broom 2 having a rod-shaped handle 4 extending in the direction of axis L and a flat sweeping body 5 attached to the tip thereof; a handle 6 having a recess 7 that opens to the front side and can accommodate the tip of the handle 4; and a dustpan 3 connected to the tip of the handle 6 and having a sweeping section 8 that is recessed and opens to the front side and can accommodate the sweeping body 5. When not in use, broom with dustpan 1 can be stored in a coupled state by storing the tip of the handle 4 of broom 2 and the sweeping body 5 in the recess 7 of the handle 6 and the sweeping section 8 of the dustpan 3, respectively. When broom with dustpan 1 is coupled to dustpan 3, the axis of broom 2 and the axis of dustpan 3 are coaxial, i.e., on axis L.
[0015] Below, we will explain the specific structure of the broom with dustpan 1, with reference to other figures. For ease of explanation, because the broom 2 is typically used with the handle 4 positioned at the top, the direction along the axis L will be referred to as the up-down direction, with the handle 4 side being referred to as the top and the wiping body 5 side being referred to as the bottom.
[0016] First, the broom 2 will be described in detail. The handle 4 is formed into a rod shape from a hard material such as synthetic resin or metal, and has a grip 9 provided at its base end in the direction of axis L and the wiping body 5 attached to its tip end. The handle 4 has a first handle 4a having the grip 9 and a second handle 4b having a smaller diameter than the first handle 4a. The first handle 4a and the second handle 4b are hollow, and the second handle 4b is inserted into the first handle 4a, allowing the first handle 4a and the second handle 4b to move relatively in the direction of axis L, thereby allowing the handle 4 to extend and retract in a telescopic manner. Note that the handle 4 can be configured to enable or disable relative movement between the first handle 4a and the second handle 4b using a known stopper.
[0017] A joint member 10 for attaching the wiping body 5 is connected to the tip of the second handle portion 4b of the handle 4. As shown in Figures 6 to 8, the joint member 10 is tubular with a first end 10a and a second end 10b at both ends in the direction of the axis L, and is provided on the first end 10a side (the handle 4 side) with a handle attachment portion 11 whose inner peripheral surface is fitted with the outer peripheral surface of the second handle portion 4b. The handle attachment portion 11 has a screw insertion hole 11a penetrating its outer peripheral surface and inner peripheral surface, and a screw 11b is fixed to the tip of the second handle portion 4b through the screw insertion hole 11a.
[0018] The joint member 10 also has a holder attachment portion 12 on the second end 10b side, the holder attachment portion 12 having a smaller diameter than the handle attachment portion 11. A cylindrical connecting portion 13 provided on the upper end of the wiping body 5 is connected to the holder attachment portion 12, and the inner peripheral surface of the connecting portion 13 is fitted into the outer peripheral surface of the holder attachment portion 12.
[0019] Describing the holder mounting portion 12 in detail, the holder mounting portion 12 has a U-shaped slit 14 penetrating from its outer circumferential surface to its inner circumferential surface, and a tongue-shaped operating portion 15 formed inside the slit 14 and elastically deformable in the radial direction, with the concave side facing the second end 10b. The operating portion 15 is supported in a cantilevered manner at a base end near the second end 10b. When an engagement button 15a provided at the tip of the free end is pressed, the operating portion 15 elastically collapses radially inward with the base end as a fulcrum, and when the pressure is released, the operating portion 15 elastically returns radially outward. As shown in FIGS. 1 and 2, when the connecting portion 13 is fitted to the holder mounting portion 12 (when the wiping body 5 is fixed to the joint member 10), the engagement button 15a of the operating portion 15 engages with a button hole 13a opened in the connecting portion 13. When the engagement button 15a is pressed, the engagement with the button hole 13a is released, so that the wiping body 5 can be removed and replaced when the wiping body 5 becomes soiled.
[0020] On the outer peripheral surface of the holder mounting portion 12, guide grooves 12a extending from the second end 10b toward the first end 10a are provided at positions 180 degrees apart in the circumferential direction. The guide grooves 12a are engaged with guide ridges (not shown) extending in the direction of axis L provided on the inner peripheral surface of the connecting portion 13. This restricts relative rotation between the holder mounting portion 12 and the connecting portion 13 about axis L, firmly fixing the wiping body 5 to the joint member 10 (i.e., the handle portion 4), and also provides a guide function when attaching the connecting portion 13 to the joint member 10.
[0021] The wiping body 5 will now be described. The wiping body 5 has a holder portion 16 connected to the handle portion 4, and a brush body 17 having one end held inside the holder portion 16 and the other end extending from the holder portion 16 to the outside.
[0022] As shown in FIGS. 9 and 10, the holder portion 16 has the connection portion 13 and a holder body 18 connected to the lower end of the connection portion 13. The holder body 18 has a shape that widens downward. Specifically, the holder body 18 has a first side end 19 at one end in the width direction and a second side end 20 at the other end, which extend toward the ear head 17 at the same angle with respect to the axis L, and the tip of the first side end 19 is located closer to the stalk 4 than the tip of the second side end 20.
[0023] A holding portion 21 for holding the spike 17 is provided at the lower end of the holder body 18. The holding portion 21 has an inclined portion 21a that is connected to the tip side of the first side end 19 and slopes diagonally downward, and an arc-shaped portion 21b that is connected to the lower end side of the inclined portion 21a and forms a gentle arc and is connected to the tip side of the second side end 20. The lower end of the inclined portion 21a is located closer to the second side end 20 than the axis L in the width direction, and therefore the width length of the inclined portion 21a is longer than the width length of the arc-shaped portion 21b.
[0024] The holder body 18 has a first surface 18a that faces the dustpan 3 (inside) when the broom 2 is attached to the dustpan 3, and a second surface 18b that faces away from the first surface 18a and away from the dustpan 3 (outside). The holder body 18 also has an engagement hole 22 that penetrates the thickness direction from the first surface 18a to the second surface 18b. The engagement hole 22 has an isosceles triangular planar shape, with its base 22a facing the bristles 17 and two oblique sides 22b, 22b extending from the base 22a toward the handle 4, which follow the slopes of the first side end 19 and second side end 20 of the holder body 18. The three apexes of the triangle of the engagement hole 22 are rounded, so that the base 22a and the oblique sides 22b, 22b are smoothly connected. The opening edges of the bottom side 22a and the oblique sides 22b, 22b on the first surface 18a side and the second surface 18b side are chamfered.
[0025] The brush head 17 is formed by bundling a plurality of synthetic resin fibers into a cylindrical shape into a fiber bundle unit 17a, and a plurality of these fiber bundle units 17a are planted in the holding portion 21 of the holder main body 18. The fiber bundle units 17a are provided in three rows in the thickness direction of the holder main body 18, extend downward from the holding portion 21 so as to gradually widen, and are cut and aligned obliquely with respect to the axis L. Specifically, the fiber bundle units 17a are cut and aligned at the same inclination angle as the inclination angle of the inclined portion 21a of the holder main body 18, and the tip of the fiber bundle unit 17a planted closest to the second side end 20 is positioned at the lowest position, and the tip of the fiber bundle unit 17a planted closest to the first side end 19 is positioned at the highest position.
[0026] Next, the dustpan 3 will be described. The handle 6 is the part that houses the joint member 10 provided at the tip of the handle 4 and the connection part 13 of the wiping body 5, and as shown in Figures 11 to 15, has a bottom piece 6a facing the front side and a pair of side pieces 6b, 6b rising from both sides of the width of the bottom piece 6a, and the recess 7 is formed by these bottom piece 6a and side pieces 6b, 6b.
[0027] Furthermore, a locking portion 23 is provided within the recess 7 of the handle 6 to lock the handle 4 in the recess 7 with the tip of the handle 4 accommodated therein. The locking portion 23 has protrusions 23a, 23a protruding inward from the tip edges 6c, 6c (opening edges of the recess 7) of the pair of side pieces 6b, 6b in the height direction so as to face each other. The locking portions 23 are provided at two locations spaced apart in the direction of the axis L, and the protrusion 23a located at one end in the direction of the axis L elastically locks to the outer peripheral surface of the tip of the handle 4 (joint member 10), while the protrusion 23a located at the other end in the direction of the axis L elastically locks to the outer peripheral surface of the connection portion 13 of the wiping body 5.
[0028] The sweeping part 8 has a widthwise length and a length in the axial direction L sufficient to completely house the wiping body 5 of the broom 2, and has a bottom surface 8a facing the front side and a pair of side surfaces 8b, 8b rising from both ends of the bottom surface 8a in the widthwise direction. The bottom surface 8a of the sweeping part 8 is connected to the bottom piece 6a of the handle 6, and each of the side surfaces 8b, 8b of the sweeping part 8 is connected to each of the side pieces 6b, 6b of the handle 6.
[0029] The side surfaces 8b, 8b of the sweeping part 8 extend apart from each other from the base end to the tip end, and accordingly, the width of the bottom surface 8a gradually increases. A recess formed by the bottom surface 8a and the side surfaces 8b, 8b and opening to the front side serves as a dust collection section 24 that collects dust that has fallen on the surface to be cleaned, such as a floor, and the bottom surface 8a that forms the dust collection section 24 is curved so as to convex toward the back side.
[0030] The sweeping section 8 also has a sweeping opening 25 formed by the leading edge of the bottom surface 8a. The sweeping opening 25 is the part that abuts against the surface to be cleaned during cleaning, and dust that has fallen on the surface to be cleaned is swept into the dust collection section 24 through the sweeping opening 25. The sweeping opening 25 is connected to the bottom surface 8a of the dust collection section 24 and has a first slope 25a that slopes upward toward the front side toward the leading edge of the bottom surface 8a, and a second slope 25b that connects to the leading end of the first slope 25a and slopes downward toward the back side toward the leading edge, and dust is swept into the dust collection section 24 through the second slope 25a. The first inclined surface 25a is a surface that forms a step between the dust storage section 24 and the second inclined surface 25b, and the provision of the first inclined surface 25a makes it difficult for dust stored in the dust storage section 24 to fall out of the second inclined surface 25b.
[0031] Furthermore, the sweeping part 8 has an engaging protrusion 26 that protrudes from the bottom surface 8a and is removably fitted into the engaging hole 22 of the holder part 16. This engaging protrusion 26 has a planar shape of an isosceles triangle provided on the base end side (handle 6 side) of the sweeping part 8, with the base part 26a facing the sweeping opening 25 and two oblique sides 26b, 26b extending from the base part 26a toward the handle 6 side, which extend along the slope of a pair of side surfaces 8b, 8b of the sweeping part 8.
[0032] The engaging protrusion 26 is tapered toward the tip in the protruding direction (height direction). Each apex of the triangle of the engaging protrusion 26 is rounded, and the base 26a and oblique sides 26b, 26b are smoothly connected. Since the engaging protrusion 26 is provided close to the handle 6, it does not take up much space in the dust collection section 24, and the engaging protrusion 26 acts as a barrier to prevent dust collected in the dust collection section 24 from spilling out of the opening at the base end of the handle 6 in the direction of the axis L.
[0033] An isosceles triangular recess 27 is formed at the tip of the engaging protrusion 26 in the height direction, and a magnet 28 having the same isosceles triangular shape as the recess 27 in a plan view is fitted into the recess 27. The magnet 28 is in the form of a thin plate, and one surface in the thickness direction (attraction surface 28a) is exposed to the outside, while the other surface is attached to the recess 27 by a joining means such as adhesive, thereby integrally joining the magnet 28 to the engaging protrusion 26. Note that the attraction surface 28a is a portion that functions as the top surface of the engaging protrusion 26, and therefore, in the following description, the attraction surface 28a will be referred to as the "top surface 28a" of the engaging protrusion 26. The top surface 28a of the engaging protrusion 26 can be magnetically attracted to a flat wall surface such as a magnetic refrigerator housing or the plate surface of a front door.
[0034] When the broom 2 and the dustpan 3 are connected to each other, the shape of the engagement hole 22 of the broom 2 and the shape of the engagement protrusion 26 of the dustpan 3 are symmetrical in the width direction with respect to the axis L. Therefore, even if the front and back surfaces of the holder part 16 are turned 180 degrees, the first surface 18a facing the dustpan 3 and the second surface 18b facing outward are interchanged, allowing the engagement protrusion 26 and the engagement hole 22 to fit together. This means that the broom 2 can be attached to the dustpan 3 without having to worry about the orientation of the front and back surfaces of the holder part 16. Note that the attachment position of the broom 2 relative to the dustpan 3 is determined by fitting the engagement protrusion 26 into the engagement hole 22, so the broom 2 and dustpan 3 can be easily integrated.
[0035] Furthermore, when the broom 2 and dustpan 3 are connected to each other as described above and the engaging protrusion 26 of the sweeping part 8 is fitted into the engaging hole 22 of the holder part 16 from the first surface 18a side toward the second surface 18b side, the top surface 28a of the engaging protrusion 26 is configured to protrude beyond the second surface 18b of the holder part 16, so that the top surface 28a can come into contact with the wall surface and be adhered when not in use.
[0036] 5 and 14, the top surface 28a is formed to protrude from a plane P that includes the heightwise leading edges 8c, 8c of the pair of side surfaces 8b, 8b of the sweeping portion 8 and is parallel to the axis L. Furthermore, the opening edges 6c, 6c of the recess 7 of the handle 6 are on the plane P and are on the same plane in the heightwise direction as the leading edges 8c, 8c of the side surfaces 8b, 8b. Therefore, when the engaging protrusion 26 is fitted into the engaging hole 22, the top surface 28a of the engaging protrusion 26 is located at the uppermost position in the heightwise direction.
[0037] Furthermore, the top surface 28a is parallel to the plane P. Therefore, when the top surface 28a is attached to the wall surface by suction, the opening edges 6c, 6c of the recess 7 and the tip edges 8c, 8c of the side surfaces 8b, 8b of the sweeping portion 8 are attached parallel to the wall surface, spaced apart from the wall surface by the amount of protrusion from the plane P to the top surface 28a.
[0038] When cleaning with the broom with dustpan 1, the broom 2 and dustpan 3 are separated, and when not in use, the broom 2 and dustpan 3 are attached together to a wall for storage. When attaching the broom 2 to the dustpan 3, the engagement projection 26 of the dustpan 3 is fitted into the engagement hole 22 of the broom 2 from the first surface 18a toward the second surface 18b. The top surface 28a of the engagement projection 28 then protrudes from the second surface 18b through the engagement hole 22, allowing the top surface 28a to be attached to the wall by adhering to the wall. When stored attached to the wall, the top surface 28a of the engagement projection 26 is attached to the wall through the engagement hole 22, and the broom 2 is held between the wall and the dustpan 3 attached to the wall, preventing the dustpan 3 and the broom 2 from separating from each other.
[0039] In this embodiment, when the engaging projection 26 of the dustpan 3 is fitted into the engaging hole 22 of the broom 2 from the first surface side to the second surface 18b side, the top surface 28a of the engaging projection 26 protrudes beyond the second surface 18b, but it may be flush with the second surface 18b as long as the top surface 28a can be attached to a wall surface. Also, the top surface 28a of the engaging projection 26 protrudes beyond the plane P that includes the tip edge 8c in the height direction of the side surface 8b, but it may be flush with the plane P as long as the top surface 28a can be attached to a wall surface in the same manner as above.
[0040] The engaging protrusions 26 and engaging holes 22 have an isosceles triangular planar shape, but may have a rectangular, circular or other planar shape as long as the engaging protrusions 26 can fit into the engaging holes 22. Furthermore, the engaging protrusions 26 and engaging holes 22 do not need to fit together tightly with no gaps, and can be configured to fit together with some play. [Explanation of symbols]
