Description

  The present invention relates to a wiping body holder comprising a gripping part for gripping a wiping body, a manually operated handle, and a connecting part for connecting both, and more specifically, a gripping part for gripping the wiping body in multiple stages with respect to the handle. The present invention relates to a double-sided push button width thin wiping body holder and a cleaning tool that can be used while being rotated and inclined.

Japanese Patent Laid-Open No. 04-28850 discloses a wiping body holder that can rotate and tilt the gripping part that grips the wiping body in multiple stages with respect to the handle. Patent Document 1 relates to a cleaning brush equipped with a sponge and a scraper and is structurally similar to the present invention, and is particularly illustrated in FIGS. 19 and 20 of the present application and will be described in detail below.
FIG. 19 is an exploded perspective view of a cleaning brush having a multi-stage rotation tilt mechanism described in Patent Document 1, and shows a mechanism for fixing the brush head A10 to the rod-shaped body A30 by tilting in multiple stages. ing.
Referring to FIG. 19, a brush head A <b> 10 is configured by inserting a sponge pinch 123 having a sponge A <b> 3 tightly inserted into a sponge pinch member attachment portion A <b> 12 and engaging the scraper A <b> 2 with the scraper attachment portion A <b> 11. Two U-shaped connecting pieces 131 having internal teeth 132 are suspended from the lower surface of the brush head A10.
The female screw forming portion 313 of the boss 315 is screwed into the male screw forming portion 311 at the tip of the rod-shaped body A30 that is a handle, the unevenness forming portion 314 is pushed into the connecting member A20, and the pin P is locked to the L-shaped notch A22. Then, the rod-shaped body A30 and the connecting member A20 are connected. Two bracket plates 2311 having internal teeth 2312 project from the tip of the connecting member A20 in which the notch A21 is drilled to constitute a bracket support 231.

In order to fix the bracket A13 of the brush head A10 to the bracket plate 231 by rotating and tilting in multiple stages, the left and right interlocking units 232 and 232, the left and right springs 233 and 233, the left and right pushing members 234 and 234, and the left and right shaft rods Since 235 and 235 are arranged and the left and right connection states are the same, only the connection structure on one side will be described.
The interlocking unit 232 having a ring-shaped protrusion 2322 formed on the inner surface of the shaft hole 2321 is inserted outward from the inside of the U-shaped connecting piece 131 so that the gear 2323 meshes with the internal teeth 132, and the gear 2323 further includes the internal teeth 2312. Are inserted outward from the inside of the bracket plate 2311 so as to mesh with each other. As a result, the gear 2323 is engaged with the internal teeth 132 and the internal teeth 2312, and the brush head A10 is fixed to the rod-shaped body A30.
One end of the spring 233 is pressed against the outer surface of the bracket plate 2311, the other end of the spring 233 is inserted into the annular groove of the abutting portion 2342, the pushing member 234 is fitted, and the shaft rod 235 is passed through the abutting portion 2342 and the gear The ring-shaped notch 2351 of the shaft rod 235 is fitted into the ring-shaped protrusion 2322 in the gear 2323. As a result, the push member 234 is integrated with the interlocking unit 232 having the gear 2323 and is prevented from coming off.

FIG. 20 is a cross-sectional view of the main part of Patent Document 1 showing a rotation prohibited state in which the push member 234 is protruded and a turnable state in which the push member 234 is pressed.
FIG. 4A shows a state in which the left and right push members 234 and 234 are protruded and are not allowed to rotate. The pressing member 234 protrudes outward from the bracket plate 2311 by the bias of the spring 233, and the shaft rod 235 pulls the interlocking unit 232 outward. Accordingly, since the gear 2323 of the interlocking unit 232 meshes with the internal teeth 132 of the U-shaped connecting piece 131 and also meshes with the internal teeth 2312 of the bracket plate 2311, the brush head A10 is prohibited from rotating and fixed in that state. It will be in the state.
FIG. 5B shows a rotatable state in which the left and right push members 234 and 234 are pushed inward. The pushing member 234 is pressed inward against the bracket plate 2311 against the spring 233 by the fingers, and the shaft rod 235 moves the interlocking unit 232 inward. Therefore, the gear 2323 of the interlocking unit 232 meshes with the internal teeth 132 of the U-shaped connecting piece 131, but is detached from the internal teeth 2312 of the bracket plate 2311, and the brush head A 10 can rotate with respect to the bracket plate 2311. As a result, it is possible to incline at an arbitrary angle with respect to the rod-shaped body A30.
When the brush head A10 is tilted to an arbitrary angle in this rotatable state and the fingers are separated from the left and right push members 234 and 234, the push members 234 and 234 protrude outward by the biasing force of the spring 233, and FIG. In the state of a), the inclination is fixed at the above angle.

The structure of Patent Document 1 is easy to handle in that it has a simultaneous pressing mechanism for the left and right pressing members 234 and 234. However, it has the following drawbacks.
First, in the push member 234, the ring-shaped notch 2351 that is an annular recess and the ring-shaped projection 2322 that is an annular protrusion are integrated with the concave-convex fitting with respect to the gear 2323 of the interlocking unit 232, and are prevented from coming off. . However, even if it fits by unevenness | corrugation, since it only fits the ring-shaped protrusion 2322 in the ring-shaped notch 2351 of the shaft rod 235 without deform | transforming, the coupling force is weak. Therefore, if the shaft rod 235 is forcibly pulled out, the ring-shaped notch 2351 comes out of the ring-shaped protrusion 2322 relatively easily, and there is a drawback that the retention prevention regulation is easily broken.
Secondly, the two interlocking units 232 each having a gear 2323 projecting from the disk are inserted between the two U-shaped connecting pieces 131 and 131 so as to project the gear 2323 outward. When the U-shaped connecting piece 131 is formed of resin, it is necessary to form the disk thick and the gear 2323 thick to increase the strength. At this time, the interval between the two U-shaped connecting pieces must be designed to be large, and at the same time, the interval between the two annular bracket plates 2311 and 2311 must be set large, which increases the mechanical structure of the apparatus. There are disadvantages.
Third, Patent Document 1 discloses only a structure in which the pressing member 234 is free to rotate when the pressing members 234 and 234 are simultaneously pressed with both fingers. That is, in the structure of Patent Document 1, there is no disclosure of a structure that makes the push member 234 stop rotating at the same time as preventing it from coming off.
Fourthly, Patent Document 1 is an invention relating to a cleaning brush, which is entirely made of metal, and is characterized by a metal design that is formed of a metal material. Therefore, a design structure for manufacturing a wiping body holder for mounting a wiping body such as a pile or wiping paper by resin molding is completely ignored and not intended.

As a wiping body holder that can rotate and tilt the gripping part that grips the wiping body in multiple stages with respect to the handle, Japanese Patent Application Laid-Open No. 2001-218719, “Patent Mop Holding Tool”, is known. As an example, Japanese Patent No. 4347465 of “Angle Adjustable Cleaning Tool” is known.
Both patent documents adopt a substantially common structure, and the first stopper and the second stopper constituting the rotating shaft part integrally move back and forth, and the head is rotated in multiple stages and has a function of tilting and locking. This is its drawback.
That is, when the second stopper is pressed with one finger to rotate and tilt the grip portion, the second stopper moves inward, but at the same time, the first stopper is also integrally pushed out and protrudes. In other words, since it is not a structure that presses both the second stopper and the first stopper inward, both the stoppers cannot be pressed with fingers, and skill is required to rotate and tilt the gripping part. There was a drawback that the user complained. Further, when the second stopper is pressed, in order to rotate the gripping part, it is necessary to pick and rotate the dirty wiping body by hand, and it is inevitable that it is unsanitary.

Then, like patent documents 4-6, the invention which arrange | positions one push button in the handle | steering-wheel part distant from the rotating shaft part close | similar to a wiping body, pushes a push button, and makes a holding | grip part rotatable. It came to be done. Patent Document 4 is Japanese Patent No. 4113740 of “Cleaning Holder and Cleaning Article Using Cleaning Tool”, Patent Document 5 is Japanese Patent No. 4041706, and Patent Document 6 is “ No. 5052249 of “Cleaning Tool”.
The structures of Patent Documents 4 to 6 are common, and one push button that can be projected and retracted is disposed on the handle part away from the rotation shaft portion, and the rotation is prohibited when the push button protrudes. A structure that can be rotated when the button is immersed is employed. Therefore, when the push button is pushed down and inserted, the gripping part begins to rotate by its own weight. Therefore, in order to stop the gripping part from rotating at a desired inclination angle, the gripping part must be gripped with fingers. Dirty and unsanitary on the body.
In addition, since the rod-shaped movable structure is built in the handle and the movable structure is engaged and disengaged by the push button protruding and retracting, the movable structure and the push button do not have to be small structures. I do not get. Therefore, although it can be used for a lightweight holder such as a paper mop using wiping paper, there is a disadvantage that it is not suitable for a somewhat heavy weight holder such as a pile mop made of yarn.

Japanese Utility Model Publication No. 04-28850 JP 2001-218719 A Japanese Patent No. 4347465 Japanese Patent No. 4113740 Japanese Patent No. 4041706 Japanese Patent No. 5052249

As described above, the structure of Patent Document 1 has the following problems. First, since the ring-shaped notch 2351 comes out of the ring-shaped protrusion 2322 relatively easily, the retention prevention regulation is easily broken. Secondly, resin molding increases the structure to increase durability. Thirdly, only a structure that is free to rotate as the push member 234 is disclosed, and no structure that makes rotation impossible at the same time as the retaining member is not disclosed. Fourthly, Patent Document 1 is a metal cleaning brush, and a design structure manufactured by resin molding is not considered at all. The structures of Patent Documents 2 and 3 have the following problems. The first stopper and the second stopper constituting the rotating shaft portion integrally move back and forth to perform a function of rotating the head in multiple stages and tilt-locking, but this is a drawback. When the second stopper is pressed with one finger, the second stopper moves inward, but at the same time, the first stopper is also integrally pushed out and protrudes. Since it is not the structure which presses both stoppers to inward, there existed a fault that a skill was required to tilt the holding | grip part, and a user dissatisfied. In addition, when the second stopper is pressed, the dirty wiping body is picked by hand in order to rotate the gripping part, which is unsanitary.
Further, in Patent Documents 4 to 6, one push button that can be projected and retracted is disposed at a handle part away from the rotation shaft portion, and the push button is protruded and the rotation is prohibited. A structure that can be rotated in a state is adopted. Therefore, when the push button is pressed and immersed, the gripping portion starts to rotate by its own weight. Therefore, in order to stop the gripping portion from rotating at a desired inclination angle, it is necessary to hold the gripping portion with fingers. At the same time, since the movable structure is engaged and disengaged by the protrusion and depression of the push button, the movable structure and the push button have to be small structures. That is, although it can be used for a lightweight holder such as a paper mop using wiping paper, there is a disadvantage that it is not suitable for a weight holder such as a pile mop made of yarn.

  Therefore, the present invention is a wiping body holder that can rotate the gripping tool in multiple stages without pressing the left and right push buttons simultaneously and touching the wiping body, and can provide a wiping body holder that is compact and thin. An object of the present invention is to provide a wiping body holder and a cleaning tool that can surely prevent the push button from coming off and at the same time can easily realize the rotation free structure and the rotation prevention structure of the left and right push buttons.

  A tenth aspect of the present invention is a cleaning tool in which the double-sided push button width thin wiping body holder according to any one of the first to ninth aspects is used, and the wiping body is mounted on the gripping tool.

According to the first aspect of the present invention, from the gripping part for mounting the wiping body, the connecting part for connecting and fixing the gripping part by rotating and tilting in multiple stages, and the handle attached to the rear side of the connecting part. A wiping body holder, and a cylindrical head centering on the head through hole in the width direction of the gripping part is projected from the gripping part, and the inner peripheral surface of the head through hole is A rail is protruded in the width direction, a small-diameter disk portion is protruded outward from the large-diameter portion, the shaft core has a lock through hole extending over the entire length in the width direction, a lock groove is provided in the large-diameter portion, and A rotation lock member having one or more engagement protrusions arranged on the outer peripheral surface of the small-diameter disk portion is provided, and the lock groove is fitted to the rail so as not to rotate inside the head through hole. A wiping body holder can be provided in which the two rotation lock members slidable in the width direction are arranged in the width direction so that the large-diameter portions face each other.
Therefore, the gripping part on which the wiping body is mounted and the head are integrated with each other by fitting the lock groove and the rail, and the two rotation lock members cannot be rotated inside the head, and the rotation lock member can be rotated by an external force. If it is moved, a structure capable of integrally rotating the gripping part and the head is provided.
Further, since the one or more engaging convex portions are arranged on the outer peripheral surface of the small-diameter disk portion of the rotation lock member, the one or more engaging convex portions are engaged with a concave portion described later to make the gripping portion parallel. It can be fixed in an inclined state including the state, and the engaging convex part can be detached from the concave part and the gripping part can be rotated to be inclined to a desired angle. In particular, if two or more engaging convex portions are engaged with two or more concave portions, the gripping portion can be reliably and firmly locked, and the tilting and fixing of the gripping portion can be ensured.

Further, according to the first aspect of the present invention, the pair of bearing protrusions are provided so as to be opposed to each other with the gap interposed therebetween at the tip of the connection pipe of the connection part, and the bearing protrusion is provided on the opposite side. It consists of an annular plate portion, an outer push button fitting portion and a bearing hole opened in the width direction, and a plurality of recesses are alternately formed along the inner peripheral edge of the annular plate portion via a protruding plate. The small-diameter disk portion of the rotation lock member is inserted into the bearing hole of the annular plate portion from the gap portion, and the engagement convex portion is disposed so as to be able to mesh with and disengage from the concave portion, and the large-diameter portion is It is possible to provide a wiping body holder in which the rotation lock member is prevented from coming out of the head through hole in contact with the annular plate portion.
Therefore, if the engaging convex portion is detached from the current concave portion, the gripping portion is rotated, and the engaging convex portion is engaged with another concave portion, the tilt state can be easily and reliably changed. . There are as many inclination angles as the number of the recesses, and the inclination can be changed in a plurality of stages. Further, since the large diameter portion abuts on the annular plate portion and the rotation lock member is prevented from coming out of the head through hole, the left and right rotation lock members are disposed inside the left and right annular protrusions. There is no escape outside. Therefore, the left and right rotation lock members can be stably held in the head through hole.

Furthermore, according to the first aspect of the present invention, the push button having the button protrusion protruding from the button disk portion is disposed outside the left and right bearing protrusions, and the left and right button protrusions are arranged on the left and right sides. The button disc is inserted into the lock through hole and the button disc is fitted into the push button inner fitting portion, the left and right push buttons are connected by spring means, and the left and right push buttons are always attached outward by the spring means. In a state of being biased, the engaging convex portion meshes with the concave portion and the gripping portion is in a rotation-inhibited state. When the left and right push buttons are pressed inward, the spring means is compressed and the engaging convex portion is It is possible to provide a wiping body holder that is detached from the recess and in which the gripping portion is rotatable.
When locking the gripping part, the left and right push buttons are moved outward by the outward biasing force of the spring means, and the rotation lock member is also forced to move outward, and the engaging convex part is an annular protrusion. The holding portion is locked and fixed to the annular protrusion in an inclined state (including a horizontal state and a reverse horizontal state).
When rotating the gripping part, if the left and right push buttons are sandwiched between fingers so as to shorten the spring means, the left and right rotation lock members also move inward, and the rotation lock member The engaging projections are detached from the recesses of the annular projections, and the left and right annular projections and the head become rotatable independently of each other.
The inclination angle can be changed by the number of the concave portions, and the gripping portion can be set to a desired inclination state by simply pressing the left and right push buttons, and the finger does not come into contact with the dirty wiping body, which is very hygienic. The name of the present invention is a double-sided push button narrow wiping body holder, which means that it has a structure that presses the left and right side push buttons and that can narrow the width of the gripping part.
Here, the spring means may be a single spring or a combination of springs as long as it is a member that protrudes and moves the left and right push buttons outward by an outward biasing force.

Further, according to the first aspect of the present invention, the large-diameter portion of the rotation lock member is formed of a large-diameter plate portion and a large-diameter protrusion protruding from the large-diameter plate portion, and the lock groove is formed. When forming the large-diameter projections and facing the large-diameter portions of the left and right rotation lock members, one large-diameter projection and the other large-diameter projection are alternately fitted as the same projection amount, A double-sided push button width thin wiping body holder configured such that the rotation lock member is thin when fitted is provided.
The greatest feature of the present invention is that the rotation lock member has a large-diameter portion formed from a large-diameter plate portion and a large-diameter projection protruding from the large-diameter plate portion, and the lock groove is formed in the large-diameter projection. Is to form. By fitting the lock groove to the rail, the rotation lock member becomes unrotatable in the head and becomes integral with the head, and if the rotation lock member is rotated by an external force, the head and the grip portion are It can be rotated with respect to the handle as a unit. That is, since a strong stress concentration is generated in the lock groove due to an external force, it is necessary to increase the strength of the lock groove. Accordingly, the lock groove is formed in the large-diameter protrusion that is formed thicker than the large-diameter plate portion and has high mechanical strength, so that the strength of the lock groove can be increased.
In addition, when the large-diameter portions of the left and right rotation lock members are opposed to each other, one large-diameter protrusion and the other large-diameter protrusion are alternately fitted as the same protrusion amount. There is an advantage that the entire thickness of the left and right rotation lock members can be designed to be relatively thin. Specifically, one large-diameter projection faces the other large-diameter plate portion, and one large-diameter plate portion faces the other large-diameter projection, so a thick large-diameter projection is a thin large-diameter plate portion. As a result of facing each other, when both face each other in a contact state, the total thickness T is a total T0 + 2t of one large-diameter projection thickness T0 and two large-diameter plate thicknesses 2t (<T0). getting thin. If two large-diameter portions having a thickness T0 + t face each other, the total thickness becomes 2T0 + 2t from the two large-diameter portion thicknesses 2T0 and the two large-diameter plate portion thicknesses 2t. Therefore, T0 + 2t <2T0 + 2t is established. It is obvious to do. The overall thickness T is an element that determines the width of the gripping portion. Since the overall thickness T can be reduced to T0 + 2t while maintaining the strength, the width of the gripping portion can be narrowed. This is the reason why the width thin wiping body holder is called. Thus, since it can be configured to be thin and thin while maintaining strength, a compact and lightweight wiping body holder can be realized.

According to the 2nd form of this invention, the said rotation lock member on either side is a double-sided pushbutton width thin wiping body holder made into the member of the same structure. As described above, in the present invention, the large-diameter portion of the rotation lock member is formed from a large-diameter plate portion and a large-diameter projection protruding from the large-diameter plate portion, and the lock groove is formed as the large-diameter projection. When the large diameter portions of the left and right rotation lock members are made to face each other, one large diameter protrusion and the other large diameter protrusion are alternately fitted with the same protrusion amount.
A rotation lock member is formed by protruding one or more large-diameter protrusions in the circumferential direction of the large-diameter plate portion, and two rotation lock members having the same structure formed as described above are arranged facing each other. Then, when one rotation lock member is rotated in the circumferential direction by a certain angle with respect to the other, one large-diameter protrusion faces the other large-diameter plate, and one large-diameter plate is the other large-diameter. It can arrange | position so that a protrusion may be faced. For example, when two large-diameter projections are formed to face each other in the diameter direction of the large-diameter plate portion, and the two rotation lock members of this structure are shifted by 90 degrees and face each other, one large-diameter projection The part can be arranged so as to face the other large-diameter plate part, and the one large-diameter plate part can be arranged so as to face the other large-diameter projection, and can be fitted alternately if they are brought close to each other. Similarly, if three large-diameter projections are provided on the large-diameter plate portion by shifting every 60 degrees, if two rotation lock members having the same structure are shifted by 60 degrees to face each other, Can be mated alternately. When one large-diameter protrusion is formed on the large-diameter plate, the facing shift angle of the two rotation lock members can be shifted not only to 180 degrees but also to an arbitrary angle.
As described above, since the rotation lock members having the same structure need only be faced to each other, it is not necessary to prepare a rotation lock member having a different structure, and labor saving can be achieved from the viewpoint of mass productivity and low cost.

According to the third aspect of the present invention, in the push button, one or more restricting claws project from the button disc portion as the button projecting portion, and the restricting claw extends from the restricting claw base to the restricting claw step surface. The inner surface of the through hole of the rotation lock member forms an annular retaining protrusion on the small-diameter disk part. A double-sided pushbutton width thin wiping body holder can be provided which is continuously expanded in diameter on the inner peripheral surface of the through hole via the inner surface of the annular retaining protrusion.
Therefore, the push buttons are arranged outside the left and right bearing projections, respectively, and the restricting claws of the left and right push buttons are forcibly fitted from the small-diameter disk portion of the rotation lock member to the annular retaining projection. Since the button disk is fitted into the push button fitting portion, the push button has its regulating claw step surface abutted against the inner surface of the annular retaining protrusion and is securely removed from the lock through hole. The stop regulation can be perfected. In addition, since the annular retaining protrusion is formed on the entire length of the circumference, the inner surface of the annular retaining protrusion is also formed on the entire length of the circumference, and even if the regulating claw circulates along the entire circumference, the annular retaining protrusion The push button can be configured to freely rotate inside the lock through-hole while being always engaged with the inner surface.
That is, according to this embodiment, it is possible to provide a double-sided push button width thin wiping body holder having both functions of preventing the push button from falling off and rotating freely.

According to the fourth aspect of the present invention, in the pushbutton, one or more restricting claws project from the button disc portion as the button projecting portion, and the restricting claw extends from the restricting claw base to the restricting claw step surface. 1 is formed from a flexible plate having a restriction claw side surface on the left and right sides through the restriction claw tip, leaving one retaining protrusion on the small-diameter disk portion on the inner peripheral surface of the through hole of the rotation lock member. The above-described retaining groove is formed, and the retaining groove can provide a double-sided pushbutton width thin wiping body holder having an inner surface of the retaining projection that is a side surface of the retaining projection and left and right retaining groove side surfaces.
Therefore, the pushbuttons are respectively arranged outside the left and right bearing projections, and the restricting claws of the left and right pushbuttons are forcibly fitted into the retaining grooves from the small-diameter disk portions of the rotation lock member. A plate portion is fitted into the push button inner fitting portion, and the push button has its regulating claw step surface abutting against the inner surface of the retaining protrusion and is securely removed from the lock through hole, so Can be realized. In addition, since the restricting claw of the push button is forcibly engaged in the retaining groove, when the size of the retaining groove is the same as the size of the restricting claw, the pressing button has a side surface of the restricting claw. Abutting on the side surface of the retaining groove, the rotation prevention is surely restricted in the lock through hole. Regardless of whether the size of the retaining groove is set to be slightly larger than the size of the restricting claw, even if a slight circular movement is allowed, the side surface of the restricting claw is always in contact with the side surface of the retaining groove, and the side surface of the push button In contact with the side surface of the retaining groove, rotation prevention is restricted in the lock through hole.
That is, according to this embodiment, it is possible to provide a double-sided pushbutton width thin wiping body holder having both functions of the pushbutton retaining prevention and the rotation prevention restriction.

According to the fifth aspect of the present invention, in the push button, the button protrusion protruding from the button disk portion is a cylindrical button protrusion, and one or more pieces in a section shape are formed in the cylindrical button protrusion. The restricting claw is formed from a flexible plate having a restricting claw step surface at the tip or intermediate position thereof and a restricting claw side surface on the left and right, and an inner peripheral surface of the through hole of the rotation lock member is A double-sided pushbutton width thin wiping body holder can be provided in which an annular retaining protrusion is formed on the small-diameter disk portion and is continuously expanded in diameter to the inner peripheral surface of the through hole via the inner surface of the annular retaining protrusion.
The cylindrical button protrusion has a structural strength due to the cylindrical structure, and can improve the durability of the push button. Since the restriction claw, which is a flexible plate, is formed on the cylindrical button protrusion, even if the restriction claw bends many times, the tubular structure absorbs deformation of the bending action and is strong in terms of strength. You can make nails. In addition, an annular retaining protrusion is formed over the entire circumference of the small-diameter disk portion on the inner peripheral surface of the through hole of the rotation lock member, and an inner surface of the annular retaining protrusion is also formed on the entire periphery.
Therefore, the push buttons are respectively arranged outside the left and right bearing projections, and the restricting claws of the left and right push buttons are forcibly fitted from the small-diameter disk portion of the rotation lock member to the annular retaining projection. The push button is reliably prevented from coming out of the lock through hole by the regulation claw step surface contacting the inner surface of the annular retaining projection. In addition, since the inner surface of the annular retaining protrusion is also formed to the full length of the circumference, the restricting claw always engages with the inner surface of the annular retaining protrusion even if it circulates along the entire circumference, and the push button is the lock It can be configured to rotate freely inside the through hole.
That is, according to the present embodiment, it is possible to provide a double-sided push button width thin wiping body holder having both functions of preventing the push button from being detached and rotating freely by using the restriction claw.

According to the sixth aspect of the present invention, in the push button, the button protrusion protruding from the button disk portion is a cylindrical button protrusion, and one or more are provided on the outer peripheral surface of the cylindrical button protrusion. The button parallel surface is formed, a restriction claw is formed in a section shape on the button parallel surface, and the restriction claw is a flexible plate having a restriction claw step surface at the tip or an intermediate position and right and left restriction claw side surfaces. In addition, the double-sided push button width thin wiping body holder can be provided in which the regulation claw step surface is provided so as to protrude outward from the button parallel surface.
The cylindrical button protrusion has a structural strength due to the cylindrical structure, and can improve the durability of the push button. Since one or more button parallel surfaces are formed on the outer peripheral surface of the cylindrical button projecting portion, and a restriction claw that is a flexible plate is formed on the button parallel surface, the restriction claw is also a parallel flexible plate. Therefore, molding is easy. Of course, even if the restricting claw bends many times, the tubular structure can absorb the deformation of the deflecting action and form a strong restricting claw.
Further, one or more lock parallel surfaces are formed on the inner peripheral surface of the through-hole of the rotation lock member, and a retaining groove is engraved on the lock parallel surface leaving a retaining projection on the small-diameter disk portion. The retaining groove has a retaining protrusion inner surface which is a side surface of the retaining protrusion and left and right retaining groove side surfaces. Since the retaining groove is a parallel surface molding, the molding is easy. The side surface of the retaining groove is also easily formed as parallel surface molding.
Further, left and right push buttons are respectively arranged outside the left and right bearing projections, and when the push buttons are inserted into the lock through holes of the rotation lock member, the button parallel surfaces come into contact with the lock parallel surfaces. Since the push button is forcibly fitted in the retaining groove and the button disk portion is fitted in the push button inner fitting portion, the stepped surface of the push button has the stepped protrusion. It comes into contact with the inner surface and is securely prevented from coming out of the lock through hole. At the same time, it is possible to provide a double-sided push button width thin wiping body holder in which the push button is reliably prevented from rotating in the lock through hole by the mutual contact between the button parallel surface and the lock parallel surface.

According to the seventh aspect of the present invention, the regulation claw is a curved section, and the tip of the section becomes the regulation claw step surface, or a regulation claw projection having a regulation claw projection slope is formed in the middle of the regulation claw. The double-sided push button width thin wiping body holder in which the end surface of the restricting claw protrusion becomes the restricting claw step surface can be provided.
According to the seventh embodiment, a specific shape of the regulating claw having the regulating claw step surface is disclosed. The first shape is a case where a curved section is formed on the side surface of the cylindrical button protrusion, and the leading end surface of the section becomes a regulation claw step surface. When inserting the cylindrical button protrusion, it is a recurring section, so it proceeds while bending the retaining protrusion inward, and finally when the tip surface (regulating claw step surface) gets over the retaining protrusion, the restricting claw Return to the inside, the regulating claw step surface abuts against the inner surface of the retaining protrusion or the inner surface of the annular retaining protrusion, and is brought into contact with each other. Yes, the retaining function is realized.
In the second shape, even if the restriction claw body does not warp, a restriction claw protrusion having a restriction claw protrusion slope is formed at the tip or in the middle, and an end surface that is a falling surface of the restriction claw protrusion is the above-described restriction claw step surface. This is the case. When a button protrusion made of a restricting claw is inserted, the restricting claw protrusion slope moves over the retaining protrusion and the restricting claw advances while bending inward. Finally, when the regulating claw step surface gets over the retaining projection or the annular retaining projection, the regulating claw returns to the inside, and the regulating claw step surface abuts against the inner surface of the retaining projection or the inner surface of the annular retaining projection. Even if it becomes a butt state and it tries to pull out the button protrusion, it cannot be pulled out, and a retaining function is realized.
In this manner, the regulation claw step surface can be formed at the tip or middle part of the regulation claw. In particular, when the regulation claw step surface is formed by the regulation claw protrusion, the regulation claw itself can be prevented from coming off in either shape even if it does not warp.

According to the eighth aspect of the present invention, spring insertion protrusions are projected from the button protrusions of the push button, and the spring insertion protrusions of the left and right push buttons are inserted into both ends of the spring means to support the spring means. A double-sided push button width thin wiping body holder can be provided.
Since the length of the spring insertion protrusion protruding in the button protrusion can be set variously, the elastic force can be adjusted with the spring means of various structures, arrangements and lengths in between, A configuration is employed in which the spring insertion protrusion is inserted to hold the spring means. In the normal state, the push button protrudes to the left and right by the outward biasing force of the spring means, so that the above-mentioned engaging convex portion engages with the concave portion and enters the rotation preventing state to prevent the gripping portion from rotating. . When the left and right push buttons are pressed with fingers, the spring means is compressed and the engaging convex portion moves inward, so that the engaging convex portion is detached from the concave portion and becomes rotatable, and the gripping portion is rotated. Can be tilted.

According to the 9th form of this invention, the double-sided pushbutton width thin wiping body holder by which the spring stop part which supports the said spring end is formed under the said spring insertion protrusion can be provided.
In the present invention, when the spring is shortened by pressing the left and right push buttons with fingers, the gripping portion can be rotated with respect to the connecting portion, i.e., the handle. A mechanism is employed in which the button protrudes from side to side and the gripping portion cannot rotate with respect to the connecting portion. In other words, in the wiping body holder of the present invention, two states are selected which are not rotatable when the spring means is extended and are rotatable when being shortened. The left and right spring ends are received by the left and right spring stops in this embodiment, and the entire length of the spring is arranged between them. Therefore, the height of the spring stop is adjusted to make it extend (unrotatable) and shortened (turned) 2 states (movable) can be operated reliably.

  Hereinafter, embodiments of a double-sided push button width thin wiping body holder and a cleaning tool according to the present invention will be described in detail with reference to the accompanying drawings.

FIG. 1 shows a double-sided pushbutton width thin wiping body according to the first embodiment (corresponding to the first, second and sixth embodiments) in which the pushbutton 40 is restrained from being prevented from being pulled out and prevented from rotating. 3 is an exploded perspective view of the holder 1. FIG. FIG. 2 is an enlarged exploded perspective view of the double-sided pushbutton width thin wiping body holder 1 according to the first embodiment of the present invention. 1 and 2 will be described below.
The double-sided push button width thin type wiping body holder 1 is inserted into a gripping part 10 to which a wiping body 94 to be described later is attached, a head 20 protruding integrally with the gripping part 10, and the inside of the head 20. The rotation lock members 30, 30, a connecting part 50 for attaching the handle 80 to the rear end, a bearing part 60 projecting from the tip of the connecting pipe 51 positioned at the top of the connecting part 50, and the bearing part 60 are gaps After the bearing protrusions 61 and 61 projecting left and right symmetrically apart from the part 67 and the head 20 through which the rotation lock members 30 and 30 are inserted are closely attached by the bearing protrusions 61 and 61, the rotation lock member 30 , 30 are constituted by pushbuttons 40, 40 which are attached to the left and right via spring means 70 from the outside.
The connecting portion 50 includes a connecting pipe 51, a partition wall 52, and a handle attaching pipe 53. The handle attaching pipe 53 is provided with an attaching button hole 54, and an attachment button of the handle 80 is used as the attaching button hole 54. The handle 80 can be attached and detached. Further, the shape of the connecting pipe tip edge 56 of the connecting pipe 51 is formed so as to have a space for mounting the head 20 on the front side.

The grip portion 10 has a long plate shape, and includes a grip portion long portion 11 on the front side of the head 20 and a grip portion short portion 12 on the rear side of the head 20, and a wiping body 94 to be described later is a grip portion long portion. 11 and the gripping part short part 12.
The head 20 has a head outer peripheral surface 21 on the outer periphery, and is formed in a cylindrical shape by opening a head through hole 22 having a head inner peripheral surface 23 inside. It is formed in order to rotate the formed grip portion 10. On the head inner peripheral surface 23, one or more rails 26 for the left side and one or more rails 26 for the right side corresponding to the left and right rotation lock members 30, 30 project in the width direction. FIG. 1 shows two rails 26 and 26 for the left and right sides, and two rails 26 and 26 for the right and left sides. The vertical direction of the left rail and the front and rear direction of the right rail are substantially orthogonal. doing. As the number of rails increases, the rotation lock member 30 is strongly integrated with the head 20 to increase the fixing strength, and the rail 26 has a rib function, so the durability of the head 20 is improved by the number of the rails. To do. A head front end face 24 and a head rear end face 25 are provided at both axial ends of the head 20.

The rotation lock members 30, 30 arranged on the left and right have the same structure, and are arranged so that the large diameter portions 31 face each other in a state of being shifted by 90 degrees from each other, so only one of them will be described. To do. The rotation lock member 30 has a structure in which a small-diameter disk portion 32 protrudes from a large-diameter portion 31, and a lock through-hole 33 having a through-hole inner peripheral surface 33a is opened at the center over the entire length in the width direction. ing. The large-diameter portion 31 is formed by forming two thick large-diameter protrusions 31b in the circumferential direction on the thin large-diameter plate portion 31a in the diameter direction. One lock groove 34 is formed in each of the two large-diameter protrusions 31b.
The number of lock grooves 34 is the same as the number of rails 26 of the head 20. In FIG. 1, two rails 26 are formed on the right side and the left side, respectively. The left rotation lock member 30 is provided with two lock grooves 34 and 34 on the upper and lower sides, while the right rotation lock member 30 is provided with two lock grooves 34 and 34 on the front and rear. Therefore, the left rotation lock member 30 has the lock grooves 34 and 34 fitted to the upper and lower rails 26 and 26. Further, the right rotation lock member 30 has lock grooves 34 and 34 fitted to the front and rear rails 26 and 26. As the number of lock grooves 34 increases, the engagement force with the rail 26 increases.

One or more engaging convex portions 35 protrude from the large diameter portion 31 on the peripheral surface of the small diameter disk portion 32, and two engaging convex portions 35, 35 protrude in FIG. At this time, in the left rotation lock member 30, the two engagement convex portions 35 protrude in the front-rear direction, and in the right rotation lock member 30, the two engagement convex portions 35 protrude in the vertical direction. . The number of the engaging convex portions 35 corresponds to the number of concave portions formed in the annular plate portion 64 to be described later. In the annular plate portion 64 in FIG. 1, the concave portions 65a and 65a, the concave portions 65b and 65b, the concave portions 65c and 65c, and the like. In addition, since two concave portions are formed, two engagement convex portions 35 and 35 are also formed. When the number of the engaging convex portions 35 increases, the meshing force with the concave portions further increases.
As will be described later, when the left engaging projections 35, 35 are engaged with the recesses 65 c, 65 c of the left annular plate portion 64, the right engagement projections 35, 35 are connected to the recess 65 a of the right annular plate portion 64. , 65a. Further, when the left engagement convex portions 35 and 35 mesh with the left concave portions 65b and 65b, the right engagement convex portions 35 and 35 mesh with the right concave portions 65b and 65b. Further, when the left engaging convex portions 35 and 35 are engaged with the left concave portions 65a and 65a, the right engaging convex portions 35 and 35 are engaged with the right concave portions 65c and 65c.

  Two lock parallel surfaces 36, 36 are formed on the inner surface 33 a of the through hole 33 of the lock through hole 33 so as to face each other on the inner surface side of the position where the engaging projections 35, 35 exist. A retaining groove 37 is formed on the surface 36. At the time of engraving, the retaining groove 37 is engraved leaving a part of the small-diameter disk portion 32 of the lock parallel surface 36, so that the remaining portion becomes a retaining protrusion 38, which is on the small-diameter disk portion 32 side. The surface becomes an inner surface 38a of the retaining protrusion, and this inner surface 38a of the retaining protrusion is combined with a restricting claw step surface 46a of the restricting claw 46, which will be described later, and serves as a retaining restricting means. That is, when the restricting claw 46 is forcibly fitted in the retaining groove 37, the restricting claw step surface 46a comes into contact with the retaining projection inner surface 38a, and the retaining prevention of the push button 40 is realized by the surface-to-surface contact. Further, the retaining groove 37 has retaining groove side surfaces 37a, 37a on the left and right sides, and controls rotation prevention of the push button 40. Therefore, the periphery of the retaining groove 37 is surrounded on three sides by the retaining protrusion inner surface 38a and the retaining groove side surfaces 37a, 37a, and the side facing the retaining protrusion inner surface 38a is opened as a cut-through.

The push button 40 is formed with a button projecting portion 42 from a button disk portion 41, and in FIGS. 1 and 2, the button projecting portion 42 is projected as a cylindrical button projecting portion 42a. A spring insertion protrusion 45 protrudes from the center of the cylindrical button protrusion 42 a, and a spring stopper 48 described later is provided at the root of the spring insertion protrusion 45. A space between the cylindrical button protrusion 42 a and the spring insertion protrusion 45 is referred to as a button recess 44. The button recess 44 means a space around the spring insertion protrusion 45.
As can be seen from FIG. 1 and FIG. 2, the left and right pushbuttons 40, 40 have the same structure and are arranged so as to circulate by 90 degrees with respect to each other, so only one of them will be described. Button parallel surfaces 43 and 43 are formed as button-side restricting surfaces on the left and right sides of the cylindrical button projecting portion 42a, and restricting claws 46 are formed as cantilever beams in the form of sections on the button parallel surfaces 43 and 43, respectively. A regulation claw step surface 46a is formed in a planar shape at the tip or middle of the regulation claw 46, regulation claw side surfaces 46b, 46b are formed on both sides, and the regulation claw 46 itself functions as a cantilever. Fulfill. The front or middle restriction claw step surface 46a functions as a retaining restriction means, and the restriction claw side faces 46b and 46b function as button side restriction surfaces BK of the rotation restriction means. A cylindrical surface may be sufficient as the internal peripheral surface of the cylindrical button protrusion part 42a, the button parallel surfaces 43 and 43 may be formed also in an internal peripheral surface, and other arbitrary shapes may be sufficient as it.

  Here, it is as follows when the concrete structures of the retaining restricting means and the rotation restricting means are summarized. First, as the retaining restriction means, the regulation claw step surface 46a of the regulation claw 46 is brought into contact with the retaining projection inner surface 38a of the retaining groove 37 and is realized by face-to-face contact. Secondly, as the rotation restricting means, the button side parallel surface 43 as the button side restricting surface comes into surface contact with the lock parallel surface 36 as the lock side restricting surface and the relative movement of the button side parallel surface 43 is prohibited. The rotation of the button 40 is prohibited. Third, as an auxiliary mechanism for the rotation restricting means, the restricting claw side surfaces 46b, 46b on both sides of the restricting claw 46 become button side restricting surfaces, and the retaining groove side surfaces 37a, 37a on both sides of the retaining groove 37 are lock side restricting surfaces. Thus, the regulating claw side surfaces 46b and 46b are brought into surface contact with the retaining groove side surfaces 37a and 37a and face each other, so that the regulating claw 46 cannot move relative to the retaining groove 37 and the rotation of the push button 40 is prohibited. The

  In the bearing portion 60, an annular plate portion 64 is formed around the center bearing hole 62 on each of the opposing surface sides of the left and right bearing protrusions 61, 61, and a push button for fitting the button disc portion 41 on the outside. A button inner fitting portion 63 is formed. The annular plate portion 64 is formed with recesses 65a and 65a in the vertical direction, recesses 65b and 65b in the inclined direction of 45 degrees, and recesses 65c and 65c in the horizontal direction so as to face each other. It exists as a partition, and is sequentially arranged in the order of recess → projection plate → recess portion → projection plate.

As described above, after the head portion 20 through which the rotation lock members 30 and 30 are inserted is tightly attached by the bearing projections 61 and 61, the spring means is applied from the outside of the small-diameter disk portions 32 and 32 of the rotation lock members 30 and 30. The left and right push buttons 40, 40 are attached via 70. The spring insertion protrusions 45, 45 of the left and right push buttons 40, 40 are respectively inserted into the left and right spring ends 72, 72 of the spring means 70, and the spring ends 72, 72 are prevented from entering by spring stop portions 48, 48 described later. The
When the left and right push buttons 40, 40 are pressed against the urging force of the spring means, the two restricting claws 46, 46 of the push button 40 are flexible plates, so that the restricting claw step surfaces 46a, 46a are prevented from being removed. The protrusions 38 and 38 bend inward, and further pass over the retaining protrusions 38 and 38 and return outward, and the restricting claws 46 and 46 are forcedly fitted into the retaining grooves 37 and 37.
At this time, since the regulating claw step surfaces 46a and 46a are in surface contact with the retaining protrusion inner surfaces 38a and 38a by surface contact, the retaining of the push button 40 is completed.
