JP7789602B2 - Rotation restraining device and cleaning jig with rotation restraining device - Google Patents

Description

The present invention relates to a rotation restraint device and a cleaning jig with a rotation restraint device.

Conventionally, cleaning jigs with handles in which a sheet for cleaning floor surfaces such as hardwood floors is attached to a sheet attachment part have been known that improve operability by allowing the angle of the handle relative to the sheet attachment part to be changed as desired. Meanwhile, cleaning jigs with handles in which a sheet for cleaning bathroom floors, walls, ceilings, etc. is attached to a sheet attachment part have been known in which the handle is fixed so that it cannot rotate, making it easier to apply force to the sheet.

As a result, users are required to own two different cleaning tools, which have similar shapes and functions, and use them depending on the area they need to clean. This places a burden on users due to issues such as the effort, cost, and storage space required.

There is a known cleaning tool that provides a locking mechanism inside the connection between the seat attachment and the handle, allowing the handle to be switched between a rotatable state and a fixed state (see, for example, Patent Document 1). With such a cleaning tool, a single tool can be used to clean a variety of locations.

Hereinafter, specific aspects of the cleaning jig with rotation suppression device 1 according to an embodiment of the present invention will be described, although the technical scope of the present invention is not limited to the illustrated examples.
For convenience, the following description will be given with the X-axis, Y-axis, and Z-axis, as well as the front-rear, left-right, and up-down directions defined as shown in FIG.

[Configuration of cleaning jig with rotation suppression device]
As shown in FIG. 1, the cleaning jig 1 with a rotation restraining device comprises a cleaning jig 100 and a rotation restraining device 200 attached to the cleaning jig 100.

[Configuration of cleaning jig]
As shown in FIG. 1, the cleaning jig 100 comprises a head portion 10 to which a cleaning sheet is attached, a handle portion 20 by which a user grips the cleaning jig 100, and a joint portion 30 that connects the head portion 10 and the handle portion 20.

(cleaning sheet)
The cleaning sheet is a sheet that is replaceably attached to the head portion 10 of the cleaning jig 100 and covers the upper and lower surfaces of the head portion 10 .

The cleaning sheet has a generally rectangular shape in plan view, with its length in the Y-axis direction.
Specifically, for example, the size in the X-axis direction is 140 mm to 240 mm, preferably 160 mm to 210 mm, and the size in the Y-axis direction is 280 mm to 340 mm, preferably 300 mm to 320 mm.

The cleaning sheet may be made of nonwoven fabric or paper, and may be dry or wet. It may also be embossed for dust collection and design reasons. The area that contacts the head unit 10 may also be folded to make it easier to attach to the head unit 10.

(Head part)
As shown in Figures 1 to 3, the head portion 10 is composed of a top surface portion 11 and a bottom surface portion 12 made of different materials, and the handle portion 20 is attached to approximately the center of the upper surface of the top surface portion 11 via a joint portion 30.

(Top part)
The top surface 11 is a roughly rectangular member in plan view that is long in the Y-axis direction and has a size of 50 mm to 150 mm, preferably 70 mm to 120 mm, in the X-axis direction, and 200 mm to 300 mm, preferably 220 mm to 270 mm, in the Y-axis direction, and is formed from a hard material such as ABS resin (acrylonitrile, butadiene, styrene copolymer synthetic resin).

2, raised portions 111 are formed on the upper surface side of the top surface portion 11 so that the vicinity of both ends in the Y-axis direction is higher, and a sunken portion 112 is formed so that the vicinity of the center in the Y-axis direction is lower.
The lower surface side of the top surface portion 11 is formed to be flat and is attached to the upper surface side of the bottom surface portion 12 .

(ridge)
As shown in Fig. 2, the raised portions 111 are formed so as to bulge upward near both ends in the Y-axis direction on the upper surface side of the top surface portion 11 in a front view. Also, as shown in Fig. 3, the raised portions 111 are formed so as to be highest near the center in the X-axis direction in a side view, and to bulge gently from the front-rear direction toward the center in the X-axis direction.

The raised portion 111 is formed so that the thickness of the head portion 10 at its highest point is 10 mm to 30 mm, preferably 15 mm to 25 mm. If the thickness of the head portion 10 is less than 10 mm, it will be difficult to insert fingers when attaching the sheet to the mounting portion 13 (described below), making the sheet more likely to come off. If the thickness of the head portion 10 is more than 30 mm, it will be difficult to fit under furniture with low legs, such as sofas or racks.

The specific placement and shape of the raised portion 111 are not limited to those described above, and can be changed as appropriate as long as the handle portion 20 can lift the first protrusion 311 when passing over it.

Furthermore, it is desirable that the raised portions 111 be formed near both longitudinal ends of the head portion 10 in a plan view, but this is not limited thereto, and they may be formed near both ends in the same direction as the alignment of the two first protrusions 311 of the first yoke portion 31 described below.

(sinking part)
2, the sunken portions 112 are formed near the center in the Y-axis direction on the upper surface of the top surface 11 so as to gently sunken from the raised portions 111 formed at both ends. The sunken portions 112 are formed at the center of the top surface 11 where the handle 20 is attached via the joint 30 so that the thickness of the head 10 is 15 mm or less, preferably 12 mm or less.

(bottom part)
1 to 3, the bottom surface portion 12 is made of a softer, elastically deformable material, such as TPE (Thermo Plastic Elastomer), compared to the top surface portion 11, and is formed to have a generally rectangular shape congruent with the top surface portion 11 in a plan view. The bottom surface portion 12 has a thickness of 1 mm to 10 mm, preferably 3 mm to 4 mm, in the Z-axis direction, and is formed so that the upper and lower surfaces are generally parallel, with the upper surface attached to the top surface portion 11.

In addition, from the perspective of dust collection performance, it is preferable that the rubber hardness of the material used for the bottom surface portion 12 be 60 to 100 (measured using durometer type A (Shore A) as specified in JIS K 6253).

(Mounting part)
Returning to Fig. 1 , attachment portions 13 are provided near the four corners of the top surface of the top surface 11 in a plan view. The attachment portions 13 are holes formed on the raised portions 111 on the top surface of the top surface 11 and provided with claw portions 131 formed around the periphery of the attachment portions 131 made of EVA (ethylene vinyl acetate copolymer) or the like, and the cleaning sheet can be attached to the head unit 10 by pushing the cleaning sheet into the claw portions 131. Specifically, the cleaning sheet is attached to the head unit 10 by closely adhering the cleaning sheet to the underside of the bottom surface 12, folding back the portion of the cleaning sheet that protrudes from the underside of the bottom surface 12 toward the top surface of the top surface 11, and pushing it into the attachment portions 13 provided on the top surface of the top surface 11.
The shape of the attachment part 13 is not limited to the above-mentioned shape as long as it allows the cleaning sheet to be attached to the head part 10.

(handle)
The handle 20 is a rod-shaped member that is used by the user to grip the cleaning tool 100 when using the tool, and as shown in Fig. 1, it comprises a handle body 21 and a grip 22. The handle 20 is rotatably connected to the head 10 via a joint 30, but the front-rear, left-right, and up-down directions will be defined in the following description when the handle 20 is placed upright on the head 10 as shown in Fig. 1.

(Handle body)
As shown in FIG. 1, the handle body 21 is a rod-shaped member formed from a hard material such as ABS resin, metal (aluminum, steel, stainless steel), polycarbonate, polypropylene, etc., and is connected at its lower end to approximately the center of the upper surface of the top surface 11 of the head 10 via a joint 30, and at its upper end to the grip 22.
Preferably, the handle body 21 is formed so that the thickness in the front-to-rear direction is thinner than the thickness in the left-to-right direction near the lower end, as shown in Figure 3. This configuration makes it easier to tilt the handle 20 to a low position.

Although the effect of making it easier to tilt the handle 20 to a low position may be reduced, the lower end of the handle body 21 may be formed to have the same thickness in the front-to-back direction and the left-to-right direction. Furthermore, for example, to prioritize the strength of the second protrusion 321 (described below), the thickness in the front-to-back direction may be greater than the thickness in the left-to-right direction.

The handle body 21 is formed to have a length in the Z-axis direction of 500 mm to 1000 mm, more preferably 600 mm to 900 mm.

(gripping part)
The grip portion 22 is the portion of the handle portion 20 that is gripped by the user when using the cleaning tool 100, and is connected to the handle body 21 at the lower end.
The gripping portion 22 has a length in the Z-axis direction of 100 mm to 400 mm, more preferably 250 mm to 350 mm, and is formed so as to be approximately circular in plan view with a diameter of 15 mm to 45 mm, more preferably 20 mm to 40 mm, at its thickest point.
The grip portion 22 may be formed as a separate member from the handle body 21, or may be formed integrally therewith.

(Joint part)
As shown in Figures 1 to 3, the joint portion 30 is formed from a first yoke portion 31 provided in approximately the center of the upper surface side of the top surface portion 11 of the head portion 10, a second yoke portion 32 provided at the lower end of the handle portion 20, and a connecting member 33 connecting the first yoke portion 31 and the second yoke portion 32.

(First yoke part)
1 to 4, the first yoke portion 31 is formed by two symmetrically shaped first protrusions 311 that face each other at a first opposing surface portion 3111 and are formed integrally with the top surface portion 11 of the head portion 10 in the center of the upper surface side of the top surface portion 11. In the present invention, the portion that is formed with two symmetrically shaped protrusions and is used for connection to other members is called the "yoke portion."

(first protrusion)
As shown in Figures 1 to 4, the first protrusion portions 311 are formed so that, when viewed from the X-axis direction, their height gradually increases toward the first opposing surface portions 3111 where the first protrusion portions 311 face each other, and they are arranged in a line along the Y-axis.

The first protrusions 311 are formed to be 5 mm to 20 mm, preferably 8 mm to 15 mm, in the X-axis direction, and 10 mm to 50 mm, preferably 15 mm to 30 mm, in the Y-axis direction. Furthermore, near the first opposing surface portions 3111 where they are highest, they are formed to be 5 mm to 15 mm, preferably 8 mm to 12 mm, in the Z-axis direction, which is equal to or higher than the raised portions 111. Furthermore, the first protrusions 311 are arranged so that the first opposing surface portions 3111 are spaced apart by 10 mm to 25 mm, preferably 15 mm to 20 mm.

(First facing surface part)
As shown in Figures 1, 2 and 4, the first opposing surface portion 3111 is the surface where the first protrusion portions 311 face each other, and is formed in an approximately rectangular shape that stands approximately vertically from the upper surface side of the top surface portion 11, and is formed so that the first opposing surface portions 3111 are parallel to each other.
As shown in FIG. 4, the first opposing surface portion 3111 has a hole 3113 formed therein.

(hole)
The hole portion 3113 is a cylindrical hole formed in the first opposing surface portion 3111, and is used for connection with the first rotation axis portion 331 of the connecting member 33 as described below.

(side part)
As shown in Figures 1, 2 and 4, the side portion 3112 is a surface of the first protrusion portion 311 that is formed continuously from both the left and right sides of the first opposing surface portion 3111 and faces the X-axis direction parallel to the YZ plane, and is formed to stand approximately vertically from the upper surface side of the top surface portion 11 of the head portion 10.

(Second yoke part)
As shown in Figures 1 to 3 and 5, the second yoke portion 32 is formed at the lower end of the handle body 21 of the handle portion 20 from two symmetrically shaped second protrusions 321 extending in the axial direction, and a second shaft member 322 spanning between the second opposing surface portions 3211 of the second protrusions 321.

(Second protrusion)
As shown in Figures 1, 3 and 5, the second protrusion portion 321 is formed integrally with the handle body 21 at both ends of the lower end of the handle body 21 in the X-axis direction in the state shown in Figure 1, so that the second opposing surface portions 3211 face each other in parallel.

2, the second protrusion 321 has a thickness of 2 mm to 6 mm, preferably 3 mm to 5 mm, in the X-axis direction, and has a width in the Y-axis direction that is approximately the same as that of the handle body 21. If the thickness in the X-axis direction is too thin, it will not be strong enough to withstand pressure during cleaning, which could lead to breakage, and if it is too thick, when the handle is tilted in the X-axis direction, it will interfere with the top surface of the head, making it difficult to tilt it to approximately parallel.
The second opposing surface portions 3211 are formed so as to have a gap of 2 mm to 10 mm, preferably 3 mm to 7 mm, between each other.

(Second shaft member)
As shown in FIG. 5, the second shaft member 322 is formed integrally with the second protrusion 321 so as to bridge the second opposing surface portions 3211 along the X axis at the center in the Y axis direction.

(Connecting member)
As shown in Figures 1 to 3, the connecting member 33 is provided in a form interposed between the first yoke portion 31 and the second yoke portion 32, and as shown in Figure 6, it is formed in a roughly triangular shape when viewed from the front, and has a first rotating axis portion 331 and a second rotating axis portion 332 whose central axes intersect at right angles without intersecting each other in a three-dimensional intersection.
The connecting member 33 is made of a material such as polyacetate.

(First rotating shaft)
As shown in Figure 6, the first rotation axis portion 331 is a portion formed at the lower end of the connecting member 33 and used to connect with the first yoke portion 31, and has cylindrical protrusions 3311 at both ends in the Y-axis direction.
The first rotation axis portion 331 is formed so that the width in the Y-axis direction, excluding the protrusions 3311, is approximately the same as the distance between the first opposing surface portions 3111 of the first protrusions 311, and the protrusions 3311 have approximately the same shape as the holes 3113. Therefore, by fitting the protrusions 3311 into the holes 3113, the connecting member 33 can be attached to the first yoke portion 31 so as to be rotatable around the Y-axis.
The central axis of the first rotation axis portion 331 shown in FIG. 6 along the Y axis is referred to as a first axis a.

(Second rotating shaft)
6 , the second rotation axis portion 332 is a portion formed at the upper end of the connecting member 33 and used for connection to the second yoke portion 32. A portion of the upper end is cut out, and the second rotation axis portion 332 has a substantially cylindrical second mounting hole 3321 that penetrates in the front-to-rear direction. The diameter of the cylindrical space formed inside the second mounting hole 3321 is substantially the same as the diameter of the second shaft member 322. The length in the X-axis direction is also formed to be substantially the same as the length of the second shaft member 322. By fitting the second shaft member 322 into the second mounting hole 3321, the connecting member 33 can be fixed to the second yoke portion 32 so as to be rotatable about the X-axis.
The central axis of the second rotation axis portion 332 shown in FIG. 6 along the X axis is referred to as a second axis b.

With the joint portion 30 configured as described above, the handle portion 20 of the cleaning jig 100 is connected to the head portion 10 so as to be freely rotatable along the first axis a and the second axis b.

[Rotation restraint device]
First Embodiment
Next, the rotation suppressing device 200 attached to the cleaning jig 100 will be described.
The rotation restraining device 200 comprises a handle attachment part 201 attached to the handle part 20 and a head attachment part 202 attached to the top surface part 11 of the head part 10 .

(Handle attachment part)
The handle attachment portion 201 is a member for attaching the rotation restraint device 200 to the handle portion 20, and is made of PP (polypropylene), PE (polyethylene), ABS resin, etc., and has a clip shape that can clamp the handle portion 20 with a metal spring, as shown in Figure 7A, for example.

(Head mounting part)
The head attachment part 202 is a member for attaching the rotation restraint device 200 to the head part 10. As shown in Fig. 7A, for example, the head attachment part 202 is made of an elastomer such as rubber, a synthetic resin, or the like, and includes a suction cup 202a that can be attached to the head part 10, and a rod-shaped connecting part 202b that connects the suction cup 202a to the handle attachment part 201 and has a predetermined flexibility.

[How to use the rotation restraint device]
A method of using the rotation restraining device 200 having the above-described configuration will now be described.
First, the clip-shaped handle attachment portion 201 is opened to clamp the handle portion 20. Next, the suction cup 202a is pressed against the top surface 11 to adhere to the head portion 10. At this time, the handle attachment portion 201 is connected to the head attachment portion 202 via the connecting portion 202b, so that the handle portion 20 and the head portion 10 are connected via the rotation restraining device 200, as shown in Figure 7B. As a result, the handle portion 20 is fixed at a predetermined angle relative to the head portion 10, and rotation can be restrained.

At this time, the angle of the handle portion 20 relative to the head portion 10 can be adjusted depending on the pressing position of the suction cup 202a.
For example, when the head mounting part 202 is fixed at a position away from the joint part 30, the height of the suction cup 202a becomes lower, and the angle of the handle part 20 becomes smaller accordingly. On the other hand, when the head mounting part 202 is fixed near the joint part 30, the height of the suction cup 202a becomes relatively higher, and the angle of the handle part 20 becomes larger accordingly.

[Effects of the Invention]
As described above, the rotational restraint device 200 of this embodiment is attached to a cleaning jig 100 which comprises a head portion 10 to which a cleaning sheet is attached, and a handle portion 20 which is rotatably connected to the head portion 10 and is gripped by the user, and fixes the handle portion 20 at a predetermined angle relative to the head portion 10, and comprises a handle attachment portion 201 which is attached to the handle portion 200, and a head attachment portion 202 which is connected to the handle attachment portion 201 and is attached to the head portion 10.

With this configuration, there is no need to purchase two different cleaning jigs to suit different applications, and the conventional cleaning jig 100 with a rotatable handle 20 can be used as is, which is economical and does not take up storage space.
In addition, regardless of a complex internal structure, the handle portion 20 can be switched between being rotatable and being fixed simply by the simple operation of attaching the rotation suppressing device 200, which is a separate member from the cleaning jig 100, to the cleaning jig 100. Therefore, there is little risk of the cleaning jig 1 with a rotation suppressing device breaking down.
Even if the rotation restraining device 200 breaks down, it is sufficient to simply purchase a new one, which has a simple structure. Therefore, it is more economical than replacing a cleaning jig with a complex internal structure.

In this embodiment, the handle attachment part 201 is in the shape of a clip, so that the handle attachment part 201 can be attached to the handle part 20 by a simple operation of clamping the handle part 20.
The head attachment part 202 is also equipped with suction cups 202a. This allows the head attachment part 202 to be attached to the head part 10 by the simple operation of pressing it against the head part 10. It is also resistant to wear even with repeated use. The angle of the handle part 20 relative to the head part 10 can be adjusted depending on the pressing position of the head attachment part 202 (the height of the suction cups 202a).

Second Embodiment
8A, the rotation restraining device 200 according to the second embodiment has a handle attachment part 201 that is cylindrical and has a hollow part 201a with an outer shape slightly larger than the outer shape of the thickest part of the handle part 20. The handle attachment part 201 is attached to the handle part 20 by inserting the handle part 20 into the hollow part 201a.
In this case, the hollow portion 201 a is first inserted into the handle portion 20 , the rotation restraining device 200 is brought close to the head portion 10 , and then the head mounting portion 202 is attached to a predetermined location on the head portion 10 .
According to this embodiment, the handle attachment portion 201 is less likely to come off the handle portion 20 .

In this embodiment, the shape of the handle attachment portion 201 is not limited to a cylindrical shape, as long as at least the hollow portion 201a has a shape that conforms to the handle portion 20. The shape of the hollow portion 201a can also be changed according to the shape of the handle portion 20, and is not limited to a circular shape. Furthermore, the material forming the handle attachment portion 201 in this embodiment is not limited to plastics such as PP, PE, and ABS resin, and elastomers such as rubber can also be used.

Third Embodiment
The rotation restraint device 200 of the third embodiment has a clip shape that clamps the portion of the head attachment portion 202 that protrudes from the head portion 10 (in this embodiment, for example, the first yoke portion 31 of the joint portion 30), as shown in Figure 8B.
In this case, the head attachment part 202 is attached to the head part 10 first, and then the handle attachment part 201 is attached to the handle part 20.
According to this embodiment, it is possible to further improve stability when operating the cleaning jig 1 with a rotation suppressing device to perform cleaning.

In this embodiment, the head mounting portion 202 is not limited to plastics such as PP, PE, and ABS resin, but can also be made of metals such as stainless steel.

Fourth Embodiment
8C, the rotation restraining device 200 according to the fourth embodiment has a spatula-shaped or rod-shaped head attachment portion 202. The head attachment portion 202 is attached to the head portion 10 by being inserted into and fitted into a recess 14 provided in the head portion 10 near the joint portion 30, as shown in FIG.
In this case, the head attachment portion 202 is first inserted into and attached to the recess 14, and then the handle attachment portion 201 is attached to the handle portion 20. Then, the head attachment portion 202 restrains the handle portion 20 from rotating in a first direction (the front-to-back direction in FIG. 8D ). Furthermore, the rotation restraint device 200 restrains the handle portion 20 from rotating in a second direction (the left-to-right direction in FIG. 8D ) that is perpendicular to the first direction in a plan view. At this time, the angle of the handle portion 20 relative to the head portion 10 can be adjusted depending on how well the head attachment portion 202 is inserted into the recess 14.

In this embodiment, the recess 14 is not limited to a hole as shown in Figure 8D, but may be a hole with a claw portion, similar to the mounting portion 13, and the head mounting portion 202 may be formed from a soft material such as rubber and attached to the head portion 10 by being pushed into the recess 14.
This configuration makes it more difficult for the head attachment portion 202 to come off the head portion 10. In addition, the claw portion can prevent dust and the like from getting into the recess 14.

[Modification]
It should be noted that the present invention is not limited to the above-described embodiments, and various modifications are possible within the scope of the invention as defined in the claims and their equivalents.

For example, Figure 8A illustrates an example in which the head attachment portion 202 of the rotation restraint device 200 is equipped with a suction cup 202a, and Figures 8B and 8C illustrate an example in which the handle attachment portion 201 of the rotation restraint device 200 is clip-shaped, but this is not limited to this. In other words, the rotation restraint device 200 may combine the configuration of the handle attachment portion 201 or head attachment portion 202 of one embodiment with the configuration of the head attachment portion 202 or handle attachment portion 201 of another embodiment.

In addition, in the above embodiments, examples have been given of the case where the handle attachment portion 201 and the head attachment portion 202 are connected by the connecting portion 202b, and the case where the head attachment portion 202 is directly attached to the handle attachment portion 201, but this is not limitative.

Specifically, for example, a first magnet is attached to a predetermined location on the handle attachment part 201 with its first pole (e.g., south pole) facing outward. Then, a second magnet, which is the head attachment part 202, is attached to a predetermined location on the head part 10 with double-sided tape or the like with its second pole (e.g., north pole) facing outward, thereby connecting the handle attachment part 201 and the head attachment part 202 by magnetic force.

In addition, while the above embodiments illustrate cases in which the handle attachment portion 201 and the head attachment portion 202 are detachably attached to the handle portion 20 and the head portion 10, respectively, this is not limited to this.
