Description

  The present invention relates to a wiping body holder provided with a connecting portion for connecting a holding portion for holding a wiping body and a handle for manual operation, and more specifically, the holding portion is rotated and inclined in multiple stages with respect to the handle. The present invention relates to a one-side push button type wiping body holder that can be used and a cleaning tool having the holder.

  Patent Document 1 (Japanese Utility Model Laid-Open No. 04-28850) is known as a wiping body holder that can rotate and tilt the holding portion for holding 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, which is illustrated in FIGS. 18 and 19 of the present application and will be described in detail below.

  FIG. 18 is an exploded perspective view of a cleaning brush having a multistage rotation tilt mechanism described in Patent Document 1, and shows a mechanism for fixing the brush head A10 by rotating and tilting the rod head A30 in multiple stages. ing. Referring to FIG. 18, 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 mounting portion A <b> 12 and engaging the scraper A <b> 2 with the scraper mounting 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. Thus, the rod-shaped body A30 is connected to the connecting member A20. 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. 19 is a cross-sectional view of a main part of Patent Document 1 showing a rotation prevention state in which the push member 234 is protruded and a turnable state in which the push member 234 is pressed.
FIG. 6A shows a rotation blocking state in which the left and right push members 234 and 234 are protruded. The push 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 prevented from rotating,
It becomes a fixed state in that 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 can be inclined 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, the push member 234 is integrated with the gear 2323 of the interlocking unit 232 by the engagement of the ring-shaped notch 2351 and the ring-shaped protrusion 2322 and is prevented from coming off, but the rotation (rotation) of the push member 234 is restricted. It is free without being. That is, since the push member 234 is freely rotatable, the brush head A10 cannot be rotated and tilted even if the push member 234 is rotated by finger friction, and the dirty brush head A10 is held by hand. There is a disadvantage that the hand is inclined and the hand is dirty. Further, even though the ring-shaped notch 2351 of the shaft rod 235 fits with the ring-shaped projection 2322 of the gear 2323 in an uneven manner, the ring-shaped notch 2351 of the shaft rod 235 is forcibly fitted into the ring-shaped projection 2322 without being deformed. Therefore, the binding force is extremely 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 the retaining structure is easily broken.

  Patent documents 2 (JP 2001-218719 A) and patent documents 3 (Japanese Patent No. 4347465) are known about a wiping body holder provided with a multi-stage rotation inclination structure. The multi-stage rotating and tilting structure according to Patent Document 2 will be described with reference to the member code of Patent Document 2. Two arms (bearing protrusions) 13 and 14 are arranged opposite to each other at the tip of the handle (handle) 1 with a gap. Then, a boss 12 extending in the same direction is projected from the rear end of the head (gripping part) 6, and the boss 12 is inserted into the gap between the two arm parts 13 and 14 to tightly attach the boss 12. Next, the first stopper 15 is inserted from the hole of the arm portion 13 to the shaft hole of the boss 12, and the second stopper 16 is inserted from the hole of the other arm portion 14 to the hole of the boss 12 via the coil spring 10, The first stopper 15 and the second stopper 16 are engaged with each other in the shaft hole, and the whole is integrally connected to be rotatable. Positioning recesses 42 are formed in the axial hole of the boss 12 at equal intervals in the circumferential direction. A positioning engagement portion 28 projects from the second stopper 16 in the circumferential direction. The positioning engagement portion 28 engages with the positioning recess 42. When combined, the head 6 becomes unrotatable. When the second stopper 16 is pressed against the coil spring 10, the positioning engagement portion 28 is detached from the positioning recess 42 and the head 6 can be rotated. Therefore, when the head 6 is rotated, the positioning engaging portion 28 is engaged with the adjacent positioning recess 42 by the urging force of the coil spring 10, and the head 6 is locked in an inclined state. In this way, the head 6 can be rotated and locked at a multi-stage tilt position.

Since the angle-adjustable cleaning tool disclosed in Patent Document 3 has a structure similar to that of Patent Document 2, when the terms of Patent Document 2 are indicated in parentheses, they are described using the member codes of Patent Document 3. The first connecting portion (arm portion) 10a and the second connecting portion (arm portion) 10b are formed opposite to each other at the tip of the handle member (handle) 4 via a gap portion. A connecting portion (boss) 11 to be inserted into the gap portion is provided at the rear end, and a large number of concave portions (positioning concave portions) 22 are formed in the circumferential direction on the inner periphery of the connecting portion 11. A first member (first stopper) 13a in which a protrusion (positioning engagement portion) 15 is formed in the circumferential direction in the first connecting portion 10a is inserted, and a second member (a first member) is inserted into the second connecting portion 10b via a compression spring 33. The second stopper) 13b is inserted and both are integrally engaged in the shaft hole 12.

  While pressing the operating head 31 of the second member 13b and compressing the compression spring 33, the first member 13a protrudes outward, the protrusion 15 is detached from the recess 22, and the sweeping material 2 is freely rotatable. Become. When the sweeping material 2 is slightly rotated, the protrusion 15 engages with the adjacent recess 22 by the restoring force of the compression spring 33, and the sweeping material 2 can be fixed in an inclined state. If the operation head 31 is continuously pressed with a finger, the sweeping material 2 can be tilt-locked at multiple tilt angles.

  In either of Patent Document 2 and Patent Document 3, the rotating shaft portion connected by the pair of first stopper and second stopper is configured to have a lock structure that tilts and locks the head in multiple stages. One of the stoppers has an unbalanced lock structure that does not relate to the tilt lock, and has the disadvantage that a sufficient lock holding force cannot be obtained because the tilt lock is performed only by the remaining one stopper.

  As another patent document relating to a wiping body holder having a multi-stage rotation tilt structure, Patent Document 4 (Patent No. 4113740), Patent Document 5 (Patent No. 4041706) and Patent Document 6 (Patent No. 5052249) )

  In the case of Patent Document 4, the description will be made with reference to the member codes of Patent Document 4. Two supporting bodies 33, 33 are opposed to the tip of the holding handle (handle) 2 through the support space 34, and the holding handle 2 is placed at an appropriate position. The operation hole 43 is opened. A rotation connecting portion 5 is projected at the rear end of the support body (gripping portion, head) 4, and concave portions 38 a to 38 d are formed on the half peripheral surface of the rotation portion 31, and the remaining half peripheral surface has a small diameter. It is a cylinder. A push button 70 protruding and retracting into the operation hole 43 is arranged inside the distal end side of the holding handle 2, and a lock member 60 protruding from a rod-like engaging portion 61 is provided via a compression coil spring 64. ing.

Dynamic inclined surfaces 51e and 51f are formed, and a compression coil spring 55 is externally mounted on the guide shaft 54.

When the pressing button 70 protrudes from the operation hole 43, the locking portion 53 is engaged with one of the recesses 38a to 38d by the urging force of the compression coil spring 55, and the rotating portion 31 becomes non-rotatable. 4 is fixed so as not to rotate. When the pressing button 70 is pressed down and inserted into the operation hole 43, the inclined pressing portions 71b and 72b formed on the pressing button 70 slide on the sliding inclined surfaces 51e and 51f, and the locking member 50 is pressed by the pressing component force. The guide shaft 54 compresses the compression coil spring 55 and the lock portion 53 is disengaged from the recesses 38a to 38d, so that the rotating portion 31 and the support body 4 are set to be rotatable. When the support body 4 is rotated by releasing the finger from the push button 70, the lock portion 53 is pushed into the adjacent recess by the restoring force of the compression coil spring 55, and the support body 4 is locked in an unrotatable state in an inclined state. . In this way, the support 4 can be rotationally locked in multiple stages at an appropriate inclination angle.

  Patent Document 6 discloses still another multi-stage rotation tilt structure. If it demonstrates with the member code | symbol of patent document 6, the attachment part 31 which formed the several concave surface 36 in the circumferential direction at the front-end | tip of the handle | steering_wheel (handle) 10 grasped with a finger | toe protrudes.

  When the engagement position is changed, the lock engagement state in the overturned state of (16A) will be described as an example. The push button member resists the spring force of the spring 6 by the contact of the spring contact portion 13. By applying a pressing force to 16 from the outside, the push button member 16, the movable body 10, and the retaining member 17 can be slid in the width direction of the holding portion 1. The movement of the movable body 10 toward the retaining member 17 side releases the lock engagement between the push button side lock engaging portions 14a to 14c and the first lock engaging portions 31 to 37. The handle H) can be rotated around the axis of the movable body 10 via the part 2. The push button member 16, the movable body 10, and the retaining member are received by the spring urging force of the spring 6 by removing the pressing force while the handle H is rotated through the connecting portion 2 and is rotated to a desired engagement position. 17 can slide back in the opposite direction so that it can be locked, and can be locked again at the other engagement position. In particular, in this embodiment, a lock engagement operation or a lock engagement release operation is possible by making the movable body 10 movable in the width direction of the holding portion 1 by the elastic biasing force of the spring 6 built in the annular groove 7. Therefore, even if the push button operation is repeated, only the pressing force is applied in the width direction, so that the holding portion 1 is not loaded in the plate thickness direction, and the buckling deformation of the holding portion 1 does not occur. It can contribute to the improvement of the durability of the cleaning tool.

  In the present invention, a single spring contact portion may be provided, but the spring contact portions 13a to 13b are formed with a plurality of removal portions 8 symmetrically with respect to the interior groove 7, and free play for each removal portion. Since it is provided so as to pass through, the spring contact portion 13 can be contacted uniformly or substantially uniformly at a plurality of locations of the annular end portion of the spring 6 housed in the annular groove 7. Accordingly, the one-side push button type that can reliably apply the external pressing force to the spring 6 and transmit the spring urging force from the spring 6 to the spring abutting portion 13 and smooth the pushing and retracting operation of the push button member 16. The wiping body holder A can be realized. In order to obtain a uniform contact state, the number of spring contact portions can be 2 or 4 or more.

When operated, the holding unit 1 has a lock release structure that allows the handle H to freely rotate and tilt in the CCW direction of FIG. 1 or the reverse clockwise direction CW. Can be done.

  Moreover, in this embodiment, the holding part 1 is made into the handle H by carrying out lock engagement of the pushbutton side lock engaging part 14 of the movable body 10 with the 1st lock engaging parts 31-37 of a rotation lock member. In addition to having a lock function portion that locks at a predetermined angle, the push button member 16 is engaged with the movable body 10 and integrated with the lock function portion to restrict free rotation, and the push button member 16 is pressed. When the push button is rotated (rotated) with the frictional force of the fingers, the holding portion is also rotated integrally. For this reason, since the holding portion can be rotated and tilted without touching the soiled wiping body at all, the sanitary condition is improved. Since the holding unit 1 is fixed and held in a predetermined tilt state, the switching operation between the rotatable state and the unrotatable state can be easily performed.

Furthermore, according to the present embodiment, since the movable body 10 is sandwiched by the push button member 16 and the retaining member 17 so as to be slidable in the width direction of the holding portion 1, the push button member can be removed. It is possible to improve the durability by firmly securing the stopper.
