Description

  The present invention relates to a cleaning tool in which a wiping body insertion portion is detachably inserted into and removed from a bag portion of a wiping body for cleaning a floor surface and a wall surface, and in particular, a handle is rotatable with respect to the wiping body insertion portion. The present invention relates to a handle rotating cleaning tool.

Conventionally, as this type of cleaning tool, a handy type or a hook-shaped long handle type has been widely used. For example, Patent Document 1 discloses a long handle type cleaning tool.
FIG. 21 shows a long handle type cleaning tool. 21 (A) and 21 (B) show a pile wiping body 40, and FIG. 21 (B) shows a long handle 41 for fixing and holding the pile wiping body 40.

  The wiping body 40 includes an elliptical base cloth 42 and a large number of piles 44 planted on the lower surface of the base cloth 42. The base fabric 42 is formed by weaving cotton fibers or synthetic fibers in a mesh shape, and on the upper surface of the base fabric 42, bag-like insertion portions 43, 43 made of the same fiber type are provided.

  The long handle holder 41 includes a mounting portion 45 attached to the base cloth 42 and a pipe-like handle 47 for manual operation. A grip 48 is provided on the distal end side of the handle 47. The tip of the handle 47 is pivotally supported by the mounting part 45 via the joint part 46. The mounting portion 45 is made of a substantially elliptical oval plate having a joint portion 46 protruding therefrom. By inserting both end portions of the mounting portion 45 into the bag-like insertion portions 43 and 43, the wiping body 40 is mounted on the long handle holder 41 to constitute a long handle handle type cleaning tool. In particular, when the wiping body is periodically replaced and rented to a user from a manufacturer or the like, the wiping body 40 needs to be separable from the handle. In order to simplify the work at the time of replacement and cleaning, the wiping body 40 is made detachable with respect to the mounting portion 45 at the end of the handle.

  In the case of FIG. 21, the tip of the handle 47 is pivotally supported by the joint portion 46 so that the handle is rotatable with respect to the wiping body insertion portion. In addition to the joint pivot mechanism, various rotation structures are used for the rotation mechanism of the handle of the cleaning tool.

  Patent Document 2 discloses a cleaning tool that rotatably supports a mop shaft of a cleaning mop formed in a roller shape. In the case of this cleaning tool, the protrusion of the universal joint is fitted to the recess of the bifurcated tip end portion of the handle so that the handle is rotatable.

  In Patent Document 3, a head in which a rod-like head main body is inserted into a cylindrical base portion of a mop body is formed, and then this head is formed into a cylindrical clamp main body in which one cylinder side portion of the head holder is vertically cut out. There has been disclosed a cleaning tool that is assembled by pressing against a notch, expanding the notch once by its elasticity, and holding the center of the head. In the case of this cleaning tool, a pivot is inserted into the cylindrical clamp body so that the handle is rotatable.

  Patent Document 4 discloses a cleaning tool that has a handle (handle) that is rotatably connected to a cleaning main body having a cleaning surface via a joint, and presses the cleaning surface against a floor surface. Yes. In this cleaning tool, one end portion of the handle portion is rotatably supported on the shaft support member connected to the cleaning main body portion, and the ratchet convex portion provided on the one end portion is provided on the shaft support member in a circumferential shape. The handle portion can be rotated with respect to the cleaning main body portion only along the inclination direction determined by the fitting position with any of the plurality of ratchet recess portions.

  In the rotation mechanisms in Patent Documents 1 to 3, the handle is pivoted by being pivotally attached to the joint member or by inserting the pivot, so that it can be rotated while the cleaning operation is repeated. There is a problem that the handle is detached or detached from the mounting portion 45 or the mop body due to loosening or abrasion of the portion. Also, in Patent Document 4, one end of the handle is bifurcated, a rotary shaft is provided inside the end, and the rotary shaft is inserted into a bearing hole formed in the shaft support member, so that the handle is predetermined. A rotational angle setting mechanism for setting at an angle fitting position is configured. However, in this rotational angle setting mechanism, the rotating shaft provided at one end of the handle is inserted into the bearing hole formed in the shaft support member, so that the rotating shaft is bent from one end of the handle during cleaning. There was a risk that the handle would come off and become uncleanable.

  In order to prevent the handle from being detached in the handle rotation type cleaning tool, it is necessary to make the handle rotation mechanism have a strong shaft support structure in which the rotation shaft does not come off.

For this purpose, a pivoting shaft support structure in which a male screw member and a sleeve-like cylindrical female screw member are used as a joint member and the male screw member is screwed to the cylindrical female screw member is not easily detached from the rotary shaft. It is considered an effective means.
However, even in such a screw-type pivot attachment structure, as the gripping member is gripped and the wiping body such as a mop is moved back and forth and left and right on the floor and cleaned repeatedly, the screw member is loosened and detached. It caused a problem of separation.
Therefore, in order to eliminate the detachment due to the loosening of the screw in the screw-type pivot attachment structure, it is necessary to provide a detachment prevention mechanism that maintains the screwed state and prevents the loosening.

In general, for example, as disclosed in Patent Documents 5 to 8, an engagement structure of a saw blade tooth portion and a claw portion is often used for a screw holding mechanism of a screw.
For example, in Patent Document 5, in order to prevent a screw thread from being damaged when a nut is excessively screwed into a bolt in a torque nut, when a predetermined torque or more is applied during screwing, it is engaged by elastic deformation. A nut cover member that is released to idle the nut is disclosed.

  Such an engagement structure is also applied to tightening a nut. For example, Patent Document 9 discloses that in a wire rod fastener in which a locking claw that is locked to a valley portion of a stud bolt is formed, an elastic locking portion that snaps to a base portion of a wire rod mounting portion is formed. Yes. Patent Document 10 discloses a bolt locking tool for a stud bolt including an inner cylinder clip and an outer cylinder clip connected to the inner cylinder clip. A ratchet and a ratchet locking claw are formed to make the inner cylinder clip rotatable in the removal direction with respect to the outer cylinder clip but not rotatable in the tightening direction.

  Also in the locking prevention mechanism, for example, Patent Document 11 discloses that ratchet teeth are formed on the neck of a container attached to a stopper of a manual liquid dispenser.

  However, in the cleaning tool, adding a complicated engagement member as an attachment member increases the number of parts and increases the cost. Moreover, since the resin molding processed material is generally used for the cleaning tool, there is a problem that it is difficult to attach the elastic deformation member in the torque nut.

  The present invention has been made in view of the above-described problems, and a solid screw-type pivoting structure in which a rotating shaft does not come off at the time of cleaning can be easily configured in a handle rotating mechanism, and a cleaning operation can be performed smoothly.

According to the first aspect of the present invention, in the joint portion that connects the handle and the insertion shaft body, the cylindrical portion of the female screw is inserted into the through hole, and the male screw is inserted into the cylindrical portion. Then, the spring washer is inserted into the female screw, and the pivot portion is formed by the cylindrical portion and the female screw, and is formed on the inner peripheral portion of the through hole on the side where the male screw is inserted. The rotation of the male screw in the direction opposite to the screwing rotation direction is restricted by the engagement between the inner peripheral engaging portion and the head engaging portion formed on the head of the male screw. A strong screw-type pivoting structure in which the moving shaft does not come off can be easily configured in the handle rotation mechanism, and a cleaning tool that can perform a smooth cleaning operation can be realized. In addition, since the inner peripheral engaging portion is formed on the inner peripheral portion of the through hole and the head engaging portion is formed on the head of the male screw made of resin, a complicated engaging member is attached. Without being added as a member, the detachment prevention mechanism that prevents the rotation shaft from being loosened and firmly holds the screwed state can be configured at low cost by resin molding. In addition, when a complicated engaging member is added as an attached member, the attached member may protrude and the appearance of the cleaning tool may be impaired, whereas the inner peripheral engaging portion is formed on the inner peripheral portion of the through hole. In addition, since the head engaging portion is formed at the head of the male screw made of resin, it becomes possible to store these engaging structures on the inner peripheral portion, which is preferred by the user layer of the cleaning tool. It also has the advantage of not affecting the compact design design.
In the insertion structure of the bearing member and the movable bearing material, either one of the bearing member or the movable bearing material can have a cross-sectional concave shape, and the other can be inserted into the concave cross-sectional shape portion. Any one of them may be an insertion piece, and the other may be a concave shape for receiving the insertion piece.
The insertion shaft body according to the present invention is preferably a hollow body in terms of weight reduction, but a solid body can also be used, and the cross-sectional shape of the shaft body does not hinder rotation in the bag portion. If it is, it is not limited to a circular shape, and an elliptical shape or a polygonal shape can be used.
Moreover, this invention is applicable not only to a long handle type cleaning tool but to short handle type cleaning tools, such as a handy type.

  According to the second aspect of the present invention, the head is formed in a cantilever shape, and is configured to protrude from the inner peripheral portion, with a flexible engagement piece swingable on the axial center side of the male screw. Engagement with the engaging protrusion enables movement of the flexible engaging piece in the screwing rotation direction and locking in the reverse rotation direction, so that the rotating shaft does not come off during cleaning. A pivoting structure can be simply configured as a handle rotation mechanism, and a cleaning tool that can perform a smooth cleaning operation can be realized.

  According to the third aspect of the present invention, the flexible engaging piece is configured to be swingable by cutting the outer periphery of the head into a cantilever shape, so that a complicated engaging member is added as an accessory member. Without the detachment prevention mechanism, the flexible engagement piece is integrally formed on the head by a resin molding process to prevent the rotation shaft from being loosened and to firmly hold the screwed state. Can be formed at low cost.

  According to the fifth aspect of the present invention, an anti-rotation engaging member that engages with the inlet side of the through hole is formed at or near the head of the female screw, and the male screw is screwed onto the female screw. Since the internal thread is prevented from idling by the engaging action of the locking member for preventing rotation when worn, the cleaning tool having excellent assembly workability that enables the male screw to be firmly tightened in the detachment preventing mechanism. Can be realized.

  In the present invention, the rotation of the male screw in the reverse direction of the screwing rotation direction is restricted by the engagement between the inner peripheral engaging portion and the head engaging portion formed on the head of the male screw. The operability improving function has improved the operability of cleaning by a rotation mechanism that has a strong screw-type pivoting structure in which the rotation shaft does not come off during cleaning, and the insertion shaft body can rotate about the axis. In addition, when cleaning a narrow space such as a fixture by gripping the handle, the wiping body can be rotated easily on the cleaning surface to realize a handle rotation type cleaning tool that can be easily and lightly cleaned. can do.

  Hereinafter, the cleaning operability of the handle rotation type cleaning tool will be described using the conventional cleaning tool of FIG.

In a state where the wiping body 40 is mounted on the mounting portion 45, most of the piles 44 are located on the back side of the mounting portion 45. Moreover, the tip of the handle 47 is fixed and held with respect to the mounting portion 45 via the joint portion 46, and does not have a degree of freedom to move around the long axis of the mounting portion 45.
However, in this conventional cleaning tool, the handle 47 can be tilted in the longitudinal direction of the mounting portion 45, but cannot be rotated around the long axis of the mounting portion 45. In order for the wiping surface of the pile 44 to hit the floor surface or the like, it is necessary to always perform the cleaning work while paying attention to the force that moves the handle 47, and the smooth cleaning work is hindered.

FIG. 22 shows a state in which the handle 47 is laid on the floor 49 and cleaned when the gap 51 such as furniture such as furniture is cleaned with the cleaning tool. (23A) of FIG. 23 shows the side surface of the cleaning tool in which the handle 47 is inclined at the laying angle θ.
In cleaning the gap, the laying angle θ with respect to the floor 49 is often set to 45 ° or less. In order to clean every corner of the gap 51 in such a laid state, it is necessary to hold the handle 47 and move it while rotating it so that it traces on the floor 49 as indicated by the arrow 50. When the handle 47 is vertically set on the joint portion 46, if the handle 47 is turned around the vertical axis, the wiping body 40 also rotates following the rotation. However, since the mounting portion 45 is inserted in close contact with the bag-like plug-in portions 43, 43, the handle 47 is held in the direction of the arrow 50 as shown in FIG. The wiping body 40 and the mounting portion 45 move integrally even if it rotates, and the movement of the wiping body 40 stops at the floor surface portion on the front side in the rotation direction, as shown by the broken line in (23B), The wiping body 40 floats on the floor surface portion on the rotation start side in response to the frictional resistance with the floor surface and floats in the air, and a smooth rotation operation cannot be performed.

  In the case of the conventional cleaning tool, the handle 47 is disposed in a T-shape with respect to the wiping body 40 in a state where the mounting portion 45 is attached to the wiping body 40 so that the handle 47 can be rotated back and forth and right and left. Therefore, a joint portion 46 is formed on the mounting portion 45. However, since the joint portion 46 is formed on the mounting portion 45, the pivotal connection point is located above the mounting portion 45, and even if a force is applied with the handle 47, the mounting portion 45 slides upward. Thus, it is difficult to sufficiently apply the force for smoothly performing the rotation operation to the mounting portion 45.

  Examining the operability of other conventional cleaning mops, for example, in the cleaning mop of Patent Document 2, a braid is fitted to each of the bent portion of the wire and each end portion of the wire. Then, the wire is twisted in a state where a synthetic fiber bundle (cleaning thread) cut to a certain length is straddled to the inside of the U-shape, and the end of the wire is bent inward. Is a mop shaft covered with braids, and the synthetic fiber bundle is radially spread around the mop shaft. However, in this cleaning tool, although the cleaning mop can be rotated to the floor plane by a roller rotation method using rolling friction, the synthetic fiber bundle is integrally formed with the mop shaft in the form of a roller. In addition to processing costs such as material costs and wire twisting, it is necessary to replace the mop for cleaning with the mop shaft after use, and it cannot be applied to rental products in which only synthetic fiber bundles are collected and reused.

  Moreover, in the cleaning tool of patent document 3, since the notch part of the cylindrical clamp main body which is a head holder is hold | gripped in the state which covered the cylindrical base part on the rod-shaped head main body as a head core material, rotation The connection point is brought close to the central axis of the head, so that the force required for head operation is easily applied to the head. However, since the rod-shaped head main body is inserted into the cylindrical base of the mop body, the rod-shaped head main body as the head core material moves integrally with the mop body, and the frictional resistance with the floor surface causes the case of FIG. Similarly, at the time of rotational cleaning of the floor surface, one end of the head is lifted from the floor surface and a smooth rotation operation cannot be performed.

Therefore, according to the sixth aspect of the present invention, the insertion shaft body is pivotally supported in the bag portion so as to be rotatable about the axis of the insertion shaft body with respect to the joint portion. Then, when cleaning a narrow space such as a fixture, when the handle is tilted at an acute angle with respect to the wiping body and rotated on the cleaning surface, the insertion shaft follows the movement of the handle. The body can be smoothly rotated so as to draw an arc while rotating inside the bag portion, and the cleaning operation can be performed easily and lightly. Further, since the handle is connected to the insertion shaft body through the joint portion, the handle can be tilted around the axis of the insertion shaft body, that is, in the front-rear direction, and the handle is rotated. Since it is rotatable by the shaft, it is possible to provide a cleaning tool with excellent operability that can grip the handle and perform a planar cleaning operation.

  For example, in the case of rental products, the inside of the bag portion is extended by repeated cleaning or the like, and the insertion state of the insertion shaft body is loosened. There is also a risk that it will be difficult to turn back and forth. Therefore, according to the seventh aspect of the present invention, since the protruding portion that contacts the inside of the bag portion is formed on the outer surface of the insertion shaft body, the rotary handle on the cleaning surface is subjected to rotational cleaning on the cleaning surface. Following the movement, the protrusion can contact the inside of the bag part, and the rotation can be performed to draw an arc while the insertion shaft rotates inside the bag part without moving back and forth, Cleaning work can be performed easily and lightly.

  According to the eighth aspect of the present invention, the shaft body main body includes a pair of rotating shaft bodies and a pair of hollow bodies fitted on the rotating shaft bodies, and the hollow bodies are independently provided. Then, each rotary shaft is pivotally supported so that it can rotate, and each rotary shaft is arranged symmetrically with respect to the connecting portion, and the pair of rotary shafts is T-shaped or substantially T-shaped with respect to the handle. When the handle is gripped to clean a narrow space such as a fixture, the handle moves when the handle is rotated at an acute angle with respect to the wiping body and rotated on the cleaning surface. Each of the hollow bodies can be rotated so as to draw an arc while rotating inside the bag portion by a pivotal support by the rotating shaft body, and can be easily and easily cleaned. A substantially T-shaped cleaning tool can be provided. In addition, in the T-shaped or substantially T-shaped cleaning tool, the insertion shaft body as the wiping body insertion portion includes the pair of rotating shaft bodies and the pair of hollow bodies externally fitted to the respective rotating shaft bodies. Therefore, the wiping body insertion portion can be rotated with a simple and inexpensive structure, and the handle rotation mechanism can be integrally provided to be tiltable.

  According to the ninth aspect of the present invention, by fixing one end of each of the rotating shaft bodies to the joint portion, the hollow body externally fitted to the rotating shaft body extends along the outer periphery of the rotating shaft body. Since the pivotal support structure that is slidably contacted can be simply configured, it is possible to reduce the price of the T-shaped or substantially T-shaped cleaning tool capable of smooth rotation operation.

  According to a tenth aspect of the present invention, each of the rotating shaft bodies is connected to the joint portion so as to be freely bent, and the pair of rotating shaft bodies are inserted into the bag portion of the wiping body. The holding mechanism includes a holding mechanism that is rigidly held by being fixed to a T shape or a substantially T shape, and a release mechanism that releases the holding state by bending each rotating shaft body in a direction in which the bag portion is detached. By the mechanism, in the holding state of the rotary shaft body, the pair of rotary shaft bodies are fixed and rigidly held in the T-shape or substantially T-shape to follow the movement of the handle, and each of the hollow bodies Of the rotating shaft body in a direction in which the rotating operation can be performed by smoothly performing the rotation operation inside the bag portion, and the holding state is released by the release mechanism and the bag portion is detached after use. Without bending and removing the wiping body directly Can be detached in stool, it is possible to provide a simple and lightly perform the cleaning work, yet T-shape or substantially T-shaped cleaning tool can be inserted and removed the wiping member insertion portion with one touch to the bag portion.

  The present invention is not limited to a T-shaped or substantially T-shaped cleaning tool, but can be applied to a cleaning tool in which the insertion shaft body is connected to an L-shape or a substantially L-shape with respect to a root portion of the handle. That is, according to the eleventh aspect of the present invention, the insertion shaft body includes an axial body whose one end is coupled to the joint portion, and a cylindrical body that is externally fitted to the axial body and pivotally supported. Since the shaft body is provided in an L shape or a substantially L shape with respect to the handle, the handle is attached to the wiping body when the handle is gripped to clean a narrow space such as a fixture. When rotating on the cleaning surface at an acute angle, the cylinder follows the movement of the handle and rotates so as to draw an arc while rotating inside the bag portion by the pivot of the shaft. It is possible to provide an L-shaped or substantially L-shaped cleaning tool that can be operated and can be easily and easily cleaned. Moreover, in the L-shaped or substantially L-shaped cleaning tool, the insertion shaft body as the wiping body insertion portion is composed of the shaft body and the cylindrical body externally fitted to the shaft body. The wiping body insertion portion can be rotated by a simple and inexpensive structure, and a handle rotation mechanism can be provided integrally so as to be tiltable.

  According to the twelfth aspect of the present invention, by fixing the one end of the shaft center body to the joint portion, the cylindrical body fitted on the shaft center body is along the outer periphery of the shaft center body. Since the pivotal support structure to be slidably contacted can be easily configured, it is possible to realize a reduction in the price of the L-shaped or substantially L-shaped cleaning tool capable of smooth rotation operation.

  According to the thirteenth aspect of the present invention, the shaft body is connected to the joint part so as to be bent, and when the shaft body is inserted into the bag part of the wiping body, the shaft body is formed into the L-shape or substantially the same. A holding mechanism that is rigidly held in a fixed L shape and a release mechanism that releases the holding state by bending the shaft body in a direction in which the bag portion is detached; In the holding state of the shaft body, the shaft body is fixed to the L-shape or the substantially L-shape and rigidly held, and follows the movement of the handle, so that the cylindrical body rotates within the bag portion. The operation is smoothly performed so that the rotation operation is possible, and after use, the holding state is released by the release mechanism, and the shaft body is bent in a direction in which the bag portion is detached, and the wiping is performed. It can be easily removed without directly grasping the body and removing it. Free to perform the cleaning operation, moreover it is possible to provide a L-shaped or substantially L-shaped cleaning tool can be inserted and removed the wiping member insertion portion with one touch to the bag portion.

According to the fourteenth aspect of the present invention, a wiping body provided with a large number of wiping materials is inserted around the entire periphery of the bag portion, and is freely moved about 360 ° around the central axis of the wiping body. Therefore, it is possible to realize a cleaning tool that can smoothly perform a cleaning operation without being restricted by the above.
For the wiping body of the present invention, for example, a wiping body in which a wiping material is implanted around the central axis on a woven fabric or a non-woven fabric base fabric by sewing or welding can be used.

Hollow portions 10e and 11e are provided in the shaft bodies 10b and 11b of the rotary shafts 10 and 11 for weight reduction. A lock button 18 is accommodated in the center of the connecting member 20. The head of the lock button 18 is exposed from the central recess 20 b of the connecting member 20. Engagement legs 18a are formed below the lock button 18, and a coil spring 22 is disposed therein. The coil spring 22 is urged by the pressing force of the coil spring 22 so that the head is exposed to the recess 20b.

  (10A) and (10B) in FIG. 10 show the unlocked state and the locked state, respectively. As shown in FIGS. 5 and 6, when the rotary shafts 10 and 11 are opened horizontally and the rotary shafts 10 and 11 are arranged in the axial direction of the connecting member 20, the engagement legs 18 a of the lock button 18 are In response to the pressing force of the coil spring 22, the coil spring 22 rises toward the concave portion 20 b and engages with the engaging portions 10 c and 11 c (see (10B)). With this engagement lock, it is possible to maintain the holding state in which the rotary shafts 10 and 11 are horizontally T-shaped as shown in FIG. The use state of the cleaning tool of FIG. 1 is completed by inserting the wiping body 1 into the insertion shaft body in this holding state.

  When the wiping body 1 is removed, when the head of the lock button 18 is pushed against the pressing force of the coil spring 22 while the long handle 2 is supported in the vertical direction, the engagement leg 18a and the engagement portion of the lock button 18 are engaged. 10c and 11c are disengaged (see (10A)), and as shown in FIG. 3 (3B) and FIG. 9, the rotary shafts 10 and 11 hang down due to their own weights in the axial direction of the long handle 2 Along with this, the legs are slightly opened and the rotary shafts 10 and 11 are in an unlocked state in which the rotary shafts 10 and 11 are substantially parallel to each other.

  Both ends of the connecting member 20 are formed in an arc shape so that the rotary shaft bodies 10 and 11 can be bent smoothly. Further, a protruding portion 20d that slightly protrudes is formed at the center of the both end portions. When the rotary shaft bodies 10 and 11 are closed along the arcuate surfaces of both end portions of the connecting member 20 by the unlocking, the end portions of the holding portions 16 and 17 are brought into contact with the protruding portions 20d. As shown in (3B) of FIG. 3, the rotary shaft bodies 10 and 11 are closed in a substantially C-shaped closed leg state in which the angle formed by the rotary shaft bodies 10 and 11 is about 10 °. Accordingly, by releasing the lock, the wiping body 1 is detached from the rotating shaft bodies 10 and 11 closed by its own weight and falls downward. Compared with the case where the rotary shaft bodies 10 and 11 are closed in a completely parallel state in both rows, the wiping body 1 may fall off at once in such a parallel unlocked state. It causes a situation to let you. On the other hand, in the present embodiment, when the lock is released, the rotating shafts 10 and 11 are in a substantially C-shape with the legs slightly opened as shown in FIG. 3 (3B), so that the dirty wiping body 1 slides down at once. It is possible to perform a detaching operation smoothly by detaching slightly slowly. Simply insert the rotary shafts 10 and 11 into the bag 23 (described later) of the wiping body 1 in the unlocked state, and simply insert the rotary shafts 10 and 11 horizontally as shown in FIG. can do. As described above, the wiping body 1 can be inserted and removed with one touch using the holding mechanism and the release mechanism of the connecting member 20.

  The distal end portions 10a and 11a of the rotary shaft bodies 10 and 11 are formed of a round-pointed cap-shaped member that facilitates insertion into the bag portion 23, and the hollow portions 10e and 11e of the shaft body bodies 10b and 11b. Is fitted. Stepped diameter-reduced portions 10f and 11f are formed in the vicinity of the end portions 10a and 11a and the holding portions 16 and 17 on both ends of the shaft bodies 10b and 11b. The pair of hollow bodies 12 and 13 are externally fitted and accommodated so as to be able to rotate in contact with the reduced diameter portions 10f and 11f, respectively. The cross sections of the hollow bodies 12 and 13 are circular as shown in (10C) of FIG. The hollow bodies 12 and 13 and the shaft body main bodies 10b and 11b may be oval or polygonal, even if they are not perfect circles. The reduced diameter portions 10f and 11f are formed in steps on the outer circumferences of the rotary shaft bodies 10 and 11 corresponding to the lengths of the hollow bodies 12 and 13, respectively. Therefore, the insertion shaft body in the present embodiment is wiped around the axis of the rotary shaft bodies 10 and 11 extending horizontally with respect to the connecting member 20 in the insertion state of the wiping body 1. It is pivotally supported in the bag part 23 of the body 1 so that it can rotate.

The handle turning mechanism of the cleaning tool according to the present embodiment will be described with reference to FIGS.
FIG. 11 is an exploded perspective view of the rotating shaft structure provided on the root member 21. FIG. 12 is a front view and a longitudinal sectional view of the root member 21.
Inside the root member 21, a pipe insertion portion 21a made of a through hole into which the inner pipe 3 is inserted is formed. In the pipe insertion portion 21a, four row-like projections 70 project in the axial direction. When the inner pipe 3 is inserted into the pipe insertion portion 21a, the insertion portion of the inner pipe 3 can be pressed and retained by the row-shaped protrusions 70. A rotary bearing 9 swelled in an enlarged diameter is formed at the lower end portion of the root member 21. Reference numeral 56 shown in FIGS. 11 and 12 indicates a processing hole used during resin molding.

  The rotary bearing 9 has a concave cross-sectional shape in which vertical grooves 67 are formed in the axial direction. Through-holes 64 and 68 are formed in the recess sandwiching the vertical groove 67 in a direction perpendicular to the axial direction of the root member 21. The through holes 64 and 68 have a shape in which the female screw 52 can be inserted. The through hole 68 has a diameter larger than that of the through hole 64 so that a stepped portion 52c on the back side of the head of the female screw 52 can be inserted. A through hole 54 a through which the female screw 52 can be inserted is also formed in the bearing piece 54 in a direction orthogonal to the axial direction of the connecting member 20. In the outer entrance portion of the through hole 64, the male screw 53 is inserted, and a diameter-enlarged recess 65 to which the head 53a of the male screw 53 is engaged is formed. A diameter-enlarged recess 68 a into which the head of the female screw 52 is inserted is formed in the outer entrance portion of the through hole 68.

  The rotation shaft of the joint portion 1 a composed of the rotary bearing 9 and the bearing piece 54 is constituted by a female screw 52 and a male screw 53 that are inserted in a state where the bearing piece 54 of the connecting member 20 is inserted into the vertical groove 67. In the present embodiment, the rotary member 9 is provided as the movable bearing member on the root member 21 and the bearing piece 54 is provided as the bearing member on the connecting member 20. However, the bearing piece 54 is provided as the movable bearing member on the root member 21 and connected. The member 20 may be provided with a rotary bearing as a bearing member so that it can be inserted.

  FIG. 13 is an enlarged view of the outer entrance portion of the through hole 64. FIG. 14 shows the side surface (14A) and the upper surface (14B) of the male screw 53. FIG. FIG. 15 shows a side surface (15A) and a plane surface (15B) of a spring washer 57 used for screwing the male screw 53. FIG. 16 shows an external view (16A) of the internal thread 52 and a vertical cross section (16B) taken along the line BB of the external appearance (16A).

  The male screw 53 is made of a resin screw with a male screw portion 58 extending from the head 53a. A set of voids 60 and a flexible engagement piece 59 are integrally formed with the head 53a in a point-symmetric manner. A cavity 60 is formed by partially cutting inwardly from the outer periphery of the head 53a, and a flexible engagement piece 59 configured to be swingable in a cantilever shape is formed. The flexible engagement piece 59 includes a main body portion along the outer periphery of the head, and a tip portion (oscillating end portion) that protrudes from the outer periphery of the head with a size substantially close to the height of a protrusion 66 described later. Between each flexible engagement piece 59, the rectangular recessed part 61 for screw fastening is recessedly provided by the axial symmetry. Using a tightening screwdriver (not shown) in which four (or two) metallic protrusion shafts fitted and arranged in the recess 61 are installed in the driver body, each protrusion shaft is inserted into the recess 61. Thus, the male screw 53 can be fastened by rotating it. Of course, you may make it conclude by engraving the-or + groove | channel in which the front-end | tip of a common minus driver or a plus driver fits.

  The diameter-enlarged recess 65 of the through hole 64 is large enough to accommodate the spring washer 57 and the head 53a of the male screw 53. As shown in FIG. 13, 16 substantially trapezoidal protrusions 66 are provided on the inner peripheral portion of the diameter-enlarged recess 65 so as to protrude toward the center at a predetermined interval. Each protrusion 66 constitutes an engagement protrusion that engages with the distal end portion of the flexible engagement piece 59. The protrusion 66 has a gentle slope 66a formed on the tightening direction of the male screw 53, that is, on the screwing rotation direction side, and an abutment surface 66b formed on the opposite side of the screwing rotation direction.

  As shown in FIG. 15, the spring washer 57 has an outer diameter that can be accommodated in the enlarged diameter recess 65 and a hole through which the female screw 52 can be inserted, and three spring bodies 69 are formed in a point-symmetric manner along the outer periphery. ing.

  The female screw 52 has a cylindrical portion 52a extending from the head in a sleeve shape and a female screw portion 52b engraved in the cylindrical portion 52a. An anti-rotation engaging member 63 projects from the back side of the head of the female screw 52. As shown in (12B) of FIG. 12, the through hole 68 has a recess 68b at the boundary with the enlarged diameter recess 68a. With the female screw 52 inserted through the through holes 64 and 68 and the longitudinal groove 67, the anti-rotation engaging member 63 is fitted into the recess 68b, whereby the male screw portion 58 of the male screw 53 is changed to the female screw portion of the female screw 52. When the screw 52 is inserted and screwed in, the female screw 52 is prevented from idling due to the engaging action of the anti-rotation engaging member 63 and the recess 68b, so that the male screw 53 can be tightened firmly. .

  In the rotation mechanism in the joint portion 1a having the above-described configuration, the cylindrical portion 52a of the female screw 52 is inserted into the through holes 64 and 68, the vertical groove 67 and the through hole 54a in the inserted state in which the rotary bearing 9 and the bearing piece 54 are inserted. In the inserted state, the male screw 53 is inserted through the spring washer 57 and inserted into the cylindrical portion 52a and screwed into the female screw portion 52b. The cylindrical portion 52a and the female screw 52 constitute a rotation shaft. When the male screw 53 is tightened by fitting the head 53a of the male screw 53 into the enlarged diameter recessed portion 65, the distal end portion of the flexible engagement piece 59 is bent toward the screw center along the gentle slope 66a of the protrusion 66. It swings and goes over the protrusion 66 in order until the tightening is completed. The contact surface 66b is formed in a direction perpendicular to the inner peripheral surface of the diameter-enlarged recess 65, and the distal end portion of the flexible engagement piece 59 moves to the contact surface 66b when moving in the direction opposite to the tightening direction. It cannot contact and bend toward the center of the screw. Therefore, the inner periphery engaging part by the some protrusion 66 formed in the inner peripheral part of the diameter expansion recessed part 65 by the side which inserts the external thread 52, and the flexible engagement formed in the head 53a of the external thread 53 The rotation of the male screw 53 in the direction opposite to the screwing rotation direction can be restricted by the engagement of the piece 59 with the head engaging portion. That is, in the cleaning tool according to the present embodiment, the screwing rotation direction is achieved by a simple configuration including the inner peripheral engagement portion by the protrusion 66 and the head engagement portion of the male screw 53 by the flexible engagement piece 59. Therefore, it is possible to perform a smooth cleaning operation by restricting the rotation in the opposite direction and providing a handle rotation mechanism having a strong screw-type pivoting structure in which the rotation axis does not come off during cleaning.

  Since the inner peripheral engaging portion is formed on the inner peripheral portion of the enlarged diameter recess 65 and the head engaging portion is formed on the head 53a of the male male screw 53, a complicated engaging member is attached. Without being added as a member, the detachment prevention mechanism that prevents the rotation shaft from being loosened and firmly holds the screwed state can be integrally formed by resin molding and can be manufactured at low cost. In addition, when a complicated engagement member is added as an attachment member, the attachment member protrudes and impairs the appearance of the cleaning tool. However, the engagement structure is formed in the diameter-enlarged recess 65, and the male screw 53 is inserted into the diameter-enlarged recess 65. The head 53a can be accommodated in the same plane, and the head of the female screw 52 can be accommodated in the enlarged diameter recess 68a. This has the advantage that it can be avoided.

  FIG. 17 schematically shows a longitudinal sectional structure of the wiping body 1. The wiping body 1 is composed of a pair of longitudinal base fabrics 25 and 26 in which a large number of pile (wiping material) groups 24 are planted on one side. An opening 27 is formed at the center of the wiping body 1, and a bag-like bag portion 23 is formed inside. The bag portion 23 is overlapped by facing the surfaces of the base fabrics 25 and 26 where the pile group 24 is not planted, and the peripheral portion of the base fabric is sewn while opening a part thereof. Is formed. In the longitudinal section of FIG. 17, a state in which the peripheral edge 31 on the lower end side of the opening 27 is sewn with the weft 29 is shown. The bag portion 23 has a T shape in which an insertion shaft body composed of the rotary shaft bodies 10 and 11 and the hollow bodies 12 and 13 can be inserted from the opening portion 27, and the pile 30 extends over the entire outer periphery of the bag portion 23. It is planted. As the material of the base fabric, it is necessary to have strength to hold the pile group, and it is preferable to use a thick canvas cloth, a cloth material such as cotton or a synthetic chemical fiber canvas, or the like. In this embodiment, a colorless nylon material is used as the pile material and the base fabric material.

FIG. 18 shows a schematic side surface and upper surface of the wiping body 1.
A part of the central portion 32 on one side in the longitudinal direction of each base fabric 25, 26 is cut out and cut off, and as shown in (18A) of FIG. Is not understood. By forming the bag portion 23, the central portion 32 becomes an introduction port of the insertion shaft body, that is, the opening portion 27.
FIG. 18B schematically shows the CC cross section of FIG. 18A. As shown in FIG. 18B, the end portions 34, 35 and 36, 37 of each base fabric are bound by a sewing thread 38, turned over, and taken into the bag portion 23. A peripheral edge 39 of each base fabric adjacent to the opening 27 of the bag portion 23 is sewn with a weft 28, and a peripheral edge 31 of each base fabric facing the opening 27 is sewn with a weft 29. Therefore, only the opening part 27 is opened in the bag part 23, and the pile 30 is planted over the entire outer periphery thereof. In FIG. 18 (18B), one section of the pile group 24 is schematically shown, and it seems that there is a gap between the piles, but the piles are planted densely without a large gap and entangled with each other. Yes.

  (19A) in FIG. 19 shows an expansion / contraction adjustment mechanism for the long handle 2. At the joint between the inner pipe 3 and the outer pipe 4, the head of the pipe button 8 is exposed at the opening of the inner pipe 3. The pipe button 8 is formed of a resin elastic piece, and includes the head, a hollow pressing deformation portion 8a integrated with the head, and a locking portion 8e that is in close contact with the joint portion. The hollow pressing deformation portion 8a has spring locking projections 8b and 8c formed vertically. A coil spring 8c is attached between the spring locking projections 8b and 8c. A pipe retaining piece 6c is fitted into a hole provided at the end of the outer pipe 4, and the cover member 6 is fitted from above to prevent the outer pipe 4 from coming off. The cover member 6 is attached to the outer pipe 4 by a cover retaining piece 6 a being fitted into a hole 6 b formed corresponding to the opening of the inner pipe 3.

  In the expansion / contraction adjustment mechanism, the head of the pipe button 8 is fitted into the opening by the pressing force of the coil spring 8c, and the joined state between the inner pipe 3 and the outer pipe 4 is maintained. When adjusting the length, the pressing force of the coil spring 8c is released by pushing the head of the pipe button 8 inward, and the outer pipe 4 is slid along the inner pipe 3 together with the cover member 6. By exposing the head of the pipe button 8 at a desired position, the length at that position can be set.

  FIG. 19 (19B) shows the attachment structure of the grip 5. FIG. The grip 5 is attached to the upper end of the outer pipe 4 by fitting the grip removal preventing piece 7 also serving as a cover into the hole 4 a provided on the upper end side of the outer pipe 4 from the opening on the lower end side of the grip 5.

In the present embodiment, a robust screw-type pivot structure having the above-described configuration is provided, and an operability improving function for improving the cleaning operability is added by the rotation mechanism of the insertion shaft body. Hereinafter, the operability improving function in the present embodiment will be described.
The insertion shaft body includes a pair of rotating shaft bodies 10 and 11 that are laterally coupled at both ends of the connecting member 20, and a pair of hollow bodies 12 and 13 that are externally fitted to the respective rotating shaft bodies 10 and 11. With these double structures, the hollow bodies 12 and 13 are pivotally supported on the rotary shafts 10 and 11 so as to be capable of rotating independently of each other, and the rotary shafts 10 and 11 are left and right with respect to the connecting member 20. It arrange | positions symmetrically and is provided in T shape or substantially T shape with respect to the long handle 2. Therefore, when the long handle 2 is gripped to clean a narrow space such as a fixture, the long handle 2 follows the movement of the long handle 2 when the handle 2 is tilted at an acute angle with respect to the wiping body 1 and rotated on the cleaning surface. Since each hollow body 12, 13 can be rotated so as to draw an arc while rotating inside the bag portion 23 by the pivot mechanism by the rotating shaft bodies 10, 11, the cleaning operation can be performed easily and lightly. It can be carried out. In addition, since the rotary shaft bodies 10 and 11 are horizontally arranged via the connecting member 20 and the bag portion 23 is inserted into each shaft body, the axial center (rotation connection point) of the rotation shaft of the joint portion. ) Is located very close to the axis of each of the rotary shafts 10 and 11, and the force applied by the long handle 2 can be accurately applied to the insertion shaft body, synergistic with the rotation function of the pivot mechanism. Thus, the rotation operation can be performed more smoothly.
Further, in the T-shaped or substantially T-shaped cleaning tool, the insertion shaft body as the wiping body insertion portion is paired with a pair of rotating shaft bodies 10 and 11 and a pair of rotating shaft bodies 10 and 11 that are externally fitted. Since the hollow bodies 12 and 13 are configured, the wiping body insertion portion can be rotated with a simple and inexpensive structure, and the handle rotation mechanism can be integrally provided to be tiltable.

  FIG. 20 shows the measurement result of the rotational operation function of the cleaning tool according to this embodiment. In this measurement, a comparison with the prior art of FIG. 21 was performed. That is, using the cleaning tool according to the present embodiment and the cleaning tool of FIG. 21, the cleaning was attempted with the handle resting on the floor surface, and the cleaning effective areas were compared. The cleaning effective area of 100% represents that the cleaning tool can be rotated to clean the entire floor without any spots. In FIG. 20, “head” means a wiping body and a wiping body insertion portion, and “sleeve” means hollow bodies 12 and 13. Moreover, the laying angle of the handle with respect to the floor surface was tried at 30 °, 45 °, and 60 °.

In the case of the conventional head fixing, although the rotation operation can be performed when the laying angle is 60 °, when the laying angle is inclined by 30 ° or 45 °, the “head” is lifted and the effective cleaning area is 65 to 65 °. It decreased to 90% (see (1) in FIG. 20). On the other hand, in the cleaning tool according to the present embodiment, smooth rotation operation is possible at any of the laying angles of 30 °, 45 °, and 60 °, and the cleaning effective area can be maintained at 100%. The rotation angle of the hollow bodies 12 and 13 itself at this time also becomes larger as the laying angle is steeply inclined to 60 °, 45 ° and 30 °, and the rotation of the hollow bodies 12 and 13 contributes to a smooth rotation operation. (See (2) in FIG. 20).
In addition, as shown in FIG. 10 (10D), the cross-sectional shape of the hollow bodies 12 and 13 is such that protrusions (ribs) 12b that contact the inside of the bag portion 23 are formed on the outer surface of the hollow body 12a. The same rotational operability was verified. The six protrusions 12b are formed along the outer periphery of the hollow body 12a. According to this verification experiment, as shown in (3) of FIG. 20, the same results as the hollow bodies 12 and 13 without ribs were obtained with respect to the effective cleaning area. Therefore, if the hollow body 12a with ribs is used, for example, in the case of rental products, the interior of the bag portion 23 is extended by repeated cleaning or the like, and the insertion state of the insertion shaft body is loosened. However, following the movement of the handle, the projecting portion (rib) 12b can be rotated to draw an arc by rotating inside the bag portion 23 while contacting the inside of the bag portion 23. A rib formed on the outer surface of the hollow body 12a in a spiral shape can be used in addition to the ribs spaced apart from each other like the protrusion 12b.

  Although the cleaning tool of the present embodiment is a case of a long cleaning tool, the present invention can be applied to a short cleaning tool or a handy type cleaning tool. In addition, a chemical fiber material or the like can be used.
