Description

  The present invention provides, for example, a wiping roller provided in a dust suction mouthpiece of a dust suction type vacuum cleaner, and wiping a dust suction mouthpiece that is configured to wipe the floor surface after sucking dust and the like from the suction portion. The present invention relates to a rotation control device suitable for being assembled to a roller or a wiping roller of a wiping / cleaning tool having no suction port.

  Conventionally, there exists a suction mouthpiece for vacuum cleaners currently disclosed by patent document 1. FIG. The suction port is provided with a suction port at a front portion in a casing having an open bottom surface and a roller storage chamber at a rear portion. In the roller storage chamber, the roller body of the wiping roller is rotatably supported by a pair of roller support shafts arranged on the left and right side walls. A rotation stopper piece is provided on the ceiling wall of the roller storage chamber facing the roller body so as to be in contact with the outer periphery of the roller body at an angle. The inclination of the rotation stopper to the outer periphery of the roller body is such that the contact resistance applied to the outer periphery of the roller body stops when the suction port advances, while the rotation stops, while when the suction port moves backward, In this relationship, the roller body is set to rotate and allow the suction mouthpiece to move.

When using the suction mouthpiece for a vacuum cleaner, the rotation of the roller body is stopped when the suction mouthpiece moves forward, so that the wiping roller wound around the roller body slides on the floor surface to perform wiping and cleaning. Is called. Then, the roller body rotates due to the retraction of the suction port, the surface of the dirty wiping roller rotates, and the new surface faces the floor surface. Wiping and cleaning will be performed.
JP 2004-195058 A

  However, in the conventional suction mouthpiece for a vacuum cleaner, when the suction mouthpiece is retreated with the surface of the wiping roller being in contact with the floor surface, the roller body rotates during the retreat. In other words, the position at which the roller body stops rotating depends on how far the suction port retreat operation continues, and it is difficult to control this. Therefore, there is a possibility that the wiping roller stops its rotation in a state where the soiled portion is again facing the floor surface by wiping and cleaning at the time of forward movement. In this case, the floor surface is rubbed with the dirty surface of the wiping roller, and the cleaning effect is reduced.

  Also, when the suction mouthpiece is retracted, the surface of the wiping roller rotates while being in contact with the floor surface during the retraction, so that the entire surface of the wiping roller gets dirty during that time, and the wiping roller is moved forward again for wiping and cleaning. At the point of time, the cleaning work is performed on the already dirty surface, so that the cleaning effect is lowered.

  Therefore, the present invention was created in view of various circumstances that existed in the past, and a rotation control device capable of controlling the rotation of the wiping roller so that wiping and cleaning can always be performed with a new surface of the wiping roller, and this It is an object of the present invention to provide a wiping / cleaning tool provided with a wiping / cleaning tool used as a wiping / cleaning tool for a vacuum cleaner.

  In order to solve the above-described problems, in the present invention, a shaft member that is supported by a fixed element and cannot rotate, and extends parallel to the shaft member, and is movable in a radial direction with respect to the shaft member. And a pair of rotating members that are arranged so as to be relatively rotatable with respect to the shaft member, and that have guide grooves that receive the ends of the needles on opposite surfaces. Urging means for urging the needle in the radial direction of the shaft member, and the guide groove of the rotating member has the shaft member from the rotation reference position to the first angle position in the first direction. A first groove that locks with the needle and prevents further rotation of the rotating member in the first direction when the first angle position is reached, The rotating member rotates relative to the second angle in the second direction from the first angle. When the second angle position is reached, the second grooves that are locked to the needle and prevent further relative rotation in the second direction of the rotating member are alternately and continuously formed. The rotation control device is formed, wherein the second angle is smaller than the first angle.

  The second angle may be a slight angle substantially close to 0 °.

  A rotation control device configured by connecting a plurality of the rotation control devices in series, and each shaft member is integrally coupled, and each rotation member rotates the rotation reference position in one direction to another rotation. It can also be arranged in a state shifted by a predetermined angle with respect to the rotation reference position of the member.

  Further, the present invention also provides a wiping and cleaning tool provided with the rotation control device, and in this wiping and cleaning tool, the fixing element comprises a casing that supports the shaft member so as not to be relatively rotatable, The roller body is provided so as to be relatively rotatable with respect to the casing and not to be relatively rotatable with respect to the rotating member, and is capable of mounting a wiping element on the outer periphery.

  Furthermore, the present invention also provides a wiping / cleaning tool / suction mouthpiece of a suction type vacuum cleaner equipped with the rotation control device. In this wiping / cleaning tool / suction mouthpiece, the fixing element includes the fixing element, The casing includes a casing that supports the shaft member so as not to rotate relative to the casing. The casing includes a dust suction path and a roller storage chamber. The casing is disposed in the roller storage chamber and is rotatable relative to the casing. And a roller body which is provided so as not to be rotatable relative to the outer periphery and which can be fitted with a wiping element on its outer periphery.

  According to the present invention, the rotation of the wiping roller is controlled so that the wiping cleaning can always be performed by the new roller surface in the wiping cleaning tool or the suction mouthpiece of the suction type vacuum cleaner provided with the rotation control device according to the present invention. be able to. That is, the wiping roller rotates by a certain angle at the time of retreating, and then slides on the surface to be cleaned in a state where the rotation is stopped. Does not appear again, or the entire roller surface is not soiled, and a new roller surface can always face the surface to be cleaned. Further, even during forward movement, since it is rotated slightly by a smaller angle than during backward movement, wiping and cleaning can be performed using a new roller surface adjacent to the roller surface used during backward movement.

The best mode for carrying out the present invention will be described below with reference to the drawings.
First, before explaining the rotation control device according to the present invention, a wiping / cleaning mouthpiece that is a typical example of an object to which the device is assembled will be described with reference to FIG.
As shown in FIG. 9A, the wiping / cleaning tool / suction mouthpiece 101 has a pair of left and right auxiliary wheels 101A and 101B at the front and rear of the casing 101a. As shown in FIG. 9B, a roller storage chamber 102 that is separated from the dust suction path 109 is formed in the casing 101a at a substantially intermediate position between both auxiliary wheels. A roller body 104 is disposed in the roller storage chamber 102. On the outer periphery of the roller body 104, for example, a porous elastic body having a hydrophilic continuous pore structure made of a sponge-like molded product of polyurethane resin, or a wiping element or wiping material 103 such as rubber having moisture absorption and moisture retention is attached. The wiping material 103 is in contact with the floor surface.

  A rotation control device P that restricts free rotation of the roller body 104 is embedded in one end portion (right end in FIG. 9B) of the roller body 104 in the axial direction. A recess 102a having a D-shaped cross section, for example, is formed on one (right side in the drawing) side wall in the roller storage chamber 102 at a position facing the rotation control device P. One end portion 5a formed in a D-shaped cross section of the shaft member 5 of the rotation control device P is inserted into the recess 102a, whereby the shaft member 5 is held non-rotatably in the casing 101a of the suction mouthpiece 101.

  Further, as shown in FIG. 9C, the other end portion in the axial direction of the roller body 104 (the left end in FIG. 9B) has a circular cross section for receiving the member 106b that pivotally supports this end portion. A recess 104a is formed. On the other side wall (left side in FIG. 9B) of the roller storage chamber 102 at a position facing the recess 104a, a roller body 104 can be attached to and detached from the roller storage chamber 102 via a hinge portion 106a. A lid 106 that can be opened and closed is provided. The lid portion 106 is configured to be freely opened and closed by rotating a locking lever 107a that can be rotated via a dial-shaped knob portion 107 at a substantially central position to lock or release a part of the side wall. A shaft portion 106 b that is substantially coaxial with the knob portion 107 protrudes from the inner wall of the lid portion 106. When the lid portion 106 is closed, the shaft portion 106b enters the concave groove 104a of the roller body 104, and supports the other end portion (the left end in FIG. 9B) of the roller body 104 so as to be relatively rotatable.

  As shown in FIG. 9 (b), the rotation control device P has a cylindrical rotating member 7 rotatably mounted on a shaft member 5 that is non-rotatably supported by the casing 101 a of the suction port 101. Yes. The outer periphery of the rotating member 7 is fitted into an enlarged diameter cylindrical recess 104c formed on the opening end (right end in the figure) side of the shaft hole portion 104b drilled along the axis of the roller body 104. Yes.

Here, the rotation control device P will be described in more detail with reference to FIGS. 1 to 8.
As shown in FIGS. 1 to 4, the rotating member 7 includes a left half 7A and a right half 7B. The half members 7A and 7B are disposed on the shaft member 5 so that the shaft member 5 is inserted into the central holes 7Ad and 7Bd, and the first retainer 8 and the second retainer 9 of the needle 13 are sandwiched from both sides. End cap portions 7 </ b> Aa and 7 </ b> Ba are provided so as to be rotatable relative to the member 5. As can be clearly understood from FIG. 4, the end cap portions 7Aa and 7Ba are formed at positions facing each other by an angular range of 90 degrees so as to surround the outer circumferences of the first retainer 8 and the second retainer 9. The quarter body parts 7Ab and 7Bb are integrally provided. In FIG. 2A, the joint of the quarter body parts 7Ab, 7Bb is indicated by 7C.

  Pin insertion grooves 7Ac and 7Bc are formed on the outer peripheries of the end cap portions 7Aa and 7Ba to accommodate a part of the pin member (not shown) at a predetermined interval. A pin insertion groove (not shown) is also formed in the inner wall of the end recess 104c of the roller body 104 at a position corresponding to this. The rotating member 7 is configured to rotate around the shaft member 5 together with the roller body 104 via a pin member (not shown) inserted into the pin insertion grooves 7Ac and 7Bc.

  As can be seen from FIGS. 1 and 5, the first retainer 8 of the needle 13 is formed so as to expand radially outward integrally with the shaft member 5 except for one place at the intermediate portion of the shaft member 5. It has a substantially disk shape. The removed portion forms a first needle moving groove 8a extending from the shaft member 5 in the radial direction.

  The second retainer 9 of the needle 13 is disposed adjacent to the first retainer 8 by inserting the shaft member 5 through the central hole 10 as can be seen from FIGS. 1, 6 and 7. The engaging member 8 is formed integrally with the shaft member 5 by engaging the engaging protrusion 8b formed on the first retainer 8 with the recess 9b. The second retainer 9 is formed in a substantially disc shape thicker than the first retainer 8, and has a second needle moving groove 9 a at a position corresponding to the first needle moving groove 8 a of the first retainer 8. In addition, a recess 11 is provided between the first and second needle moving grooves 8a and 9a to accommodate the support member for the needle 13.

  As clearly shown in FIG. 6, the support member of the needle 13 is configured so that the needle 13 is held parallel to the shaft member 5 at an intermediate portion thereof, and the needle 13 can be moved in both the radial direction and the external direction. Thus, it consists of a pair of left and right spring members 12 that support the needle holder 14 from both sides. The spring member 12 has one end attached to a spring attachment portion 11 a provided in the needle support member accommodation recess 11 located on both sides of the shaft member 5 and the other end attached to a spring attachment portion 14 a provided on both sides of the needle holder 14. The needle 13 is urged radially inward of the shaft member 5. The spring member 12 may be attached so as to urge the needle 13 outward in the radial direction of the shaft member 5.

  As can be seen from the above description, the retainers 8 and 9 of the needle 13 are operatively integrated with the shaft member 5 that is non-rotatably held in the casing 101a of the suction mouthpiece 101. The rotating member 7 disposed so as to surround the retainers 8 and 9 is configured to rotate around the shaft member 5 operatively and integrally with the roller body 104. Therefore, the retainers 8 and 9 and the rotating member 7 are relatively rotatably arranged.

  The end portion of the needle 13 as shown in FIG. 3 is accommodated in the opposing surfaces of the left half body 7A and the right half body 7B that are disposed to face each other with the retainers 8 and 9 interposed therebetween. The guide grooves 15 are formed so as to be symmetrical.

  A specific configuration of the guide groove 15 will be described with reference to FIGS. 3 and 4A to 4B, taking the left half 7A as an example. A relatively long second extending from the vicinity of the central hole 7Ad of the left half 7A toward the outer peripheral edge along the tangent line of the central hole 7Ad, and curved in the counterclockwise direction in the drawing along the outer peripheral edge in the vicinity of the outer peripheral edge. From the one-direction rotation allowance groove 15a, the first direction rotation prevention portion 15b extending inward in the radial direction from the terminal portion of the first direction rotation allowance groove 15a in the vicinity of the outer peripheral edge, and the first direction rotation prevention portion 15b. A relatively short second direction rotation allowance groove 16a extending in the middle clockwise direction, and a second direction rotation prevention portion 16b extending radially inward from the end portion of the second direction rotation allowance groove 16a to the vicinity of the shaft member 5 again, The set of these rotation permissible grooves and rotation preventing portions 15a, 15b, 16a, 16b is alternately repeated, and the whole is configured as an endless groove surrounding the shaft member 5.

  The number of the first direction rotation allowance grooves 15a and the second direction rotation allowance grooves 16a of the guide groove 15 is shown as five in FIG. 3, but for example, four as shown in FIG. Alternatively, as shown in FIG. 12B, an arbitrary number such as eight may be formed as necessary. However, in any case, the first direction rotation allowance groove 15a is long and the second direction rotation allowance groove 16a is short.

  In the first direction rotation preventing portion 15b and the second direction rotation preventing portion 16b, the needle 13 is instantaneously applied to the radially inner ends of the rotation preventing portions 15b and 16b by the biasing force of the spring member 12. , Stops at the end, stops the rotation of the rotating member 7 and simultaneously prevents the roller body 104 from rotating.

  With such a configuration of the guide groove 15, the roller body 104 is configured such that the needle 13 is engaged with the rotation preventing portions 15 b and 16 b at the terminal portion of the first direction rotation allowance groove 15 a or the second direction rotation allowance groove 16 a, thereby rotating the rotating member 7. Until the rotation is blocked, the first direction rotation allowance groove 15a and the second direction rotation allowance groove 16a can rotate in the opposite direction within a predetermined angle range. In this case, the rotation angle in the second direction is preferably less than or equal to one half of the rotation angle in the first direction.

  Since the rotation control device P is configured as described above, for example, when the suction mouthpiece 101 is moved in one of the forward direction and the backward direction in the first direction, the rotation member 7 and the roller body 104 When the suction mouthpiece 101 is moved in the other second direction by allowing the rotation to the first predetermined angle and the suction mouthpiece 101 is moved in the other second direction, the roller body 4 together with the rotating member 7 has a slight second predetermined angle. Only rotating will prevent substantial rotation.

  At this time, as shown in FIG. 12B, when the number of the first direction rotation allowance grooves 15a and the second direction rotation allowance grooves 16a is as large as, for example, eight, Since the contact surface of the roller body 104 with respect to the floor surface is sequentially moved by 1/8 of the entire circumference for each movement, the number of times that the new surface can be wiped and cleaned is increased.

  In addition, as shown in FIG. 12C, when the needle 13 is urged radially outward of the shaft member 5 by the elastic force of the spring member 12, the first direction rotation allowance groove 15 a is formed in the shaft member 5. The direction extending from the vicinity of FIG. 5 is the clockwise direction in the drawing, the direction in which the second direction rotation allowing groove 16a extends from the first direction rotation preventing portion 15b is the counterclockwise direction in the drawing, and the direction in which the guide groove 15 extends is the needle 13 May be opposite to the example in which the shaft member 5 is urged inward in the radial direction of the shaft member 5.

  Further, as shown in FIGS. 12 (a) and 12 (d), a raised portion 17 is formed in front of the curved portion in the vicinity of the outer peripheral edge portion of the first direction rotation allowance groove 15a, and the roller body 104 has a certain level or more. Only when the torque is applied, the needle 13 may move over the raised portion 17 and rotate. In this case, the swell portion 17 functions as a torque restricting means that prevents the rotation of the rotating member 7 at a torque below a certain level due to an increase in contact pressure with the needle 13.

Next, an example of use and operation of the rotation control device P using the rotating member 7 having the guide groove 15 shown in FIG. 3 will be described with reference to FIG.
FIG. 8A shows the reference position of the rotating member 7 in a state in which the needle 13 that is always located on the vertical line passing through the shaft member 5 is locked to the first direction rotation preventing portion 15b.
When the suction mouthpiece 101 is moved in the forward direction (left direction in the figure) in order to perform wiping and cleaning with the suction mouthpiece 101, the rotating member 7 moves from the reference position in FIG. 8A with the rotation of the roller body 104. 8 is rotated counterclockwise, but since the second direction rotation allowance groove 16a has a short distance, it immediately engages with the needle 13 and rotates the roller body 104 counterclockwise at an angle of about 18 degrees. Allow only up to position. The needle 13 hits the second direction rotation preventing portion 16b at this position, and prevents the roller body 104 from rotating counterclockwise. At this time, as shown in FIG. 8 (b), the needle 13 is attracted in the direction toward the shaft member 5 along the second direction rotation prevention portion 16b by the biasing force of the spring member 12, and the second direction rotation prevention. The portion 16b is locked at a position closest to the shaft member 5. At this time, the wiping material 103 of the roller body 104 is in contact with the floor surface at a position near C in the middle of C and D on the outer peripheral surface of the rotating member 7 in FIG. 8B, and can be wiped and cleaned in this state. Become.

  Further, when the suction mouthpiece 101 is moved in the backward direction (rightward in the figure) from this state and the wiping surface of the wiping material 103 is changed, the rotating member 7 is rotated in the clockwise direction in FIG. The rotating member 7 does not engage with the needle 13 over a relatively long distance of the first direction allowing groove 15a, and the roller body 104 is allowed to rotate clockwise to a position of about 90 degrees. Thereafter, the roller body 104 becomes non-rotatable when the needle 13 abuts against the first direction rotation preventing portion 15b. At this time, as shown in FIG. 8C, the needle 13 is attracted in the direction toward the shaft member 5 along the first direction rotation preventing portion 15b by the biasing force of the spring member 12, and the first direction rotation is prevented. The portion 15b is locked at a position closest to the shaft member 5. As a result, the wiping material 103 of the roller body 104 is in contact with the floor surface at a substantially central position between D and E on the outer peripheral surface of the rotating member 7 in FIG.

  If the suction mouthpiece 101 is moved in the forward direction from this state and wiping is performed again, the second direction rotation allowance groove 16a has a short distance so that the needle 13 is immediately locked. The rotation of the roller body 104 in the counterclockwise direction is allowed only up to a position of about 18 degrees, and the state shown in FIG. 8B is obtained. However, since the roller body 104 has rotated about 18 degrees counterclockwise from the state of FIG. 8C, the wiping material 103 of the roller body 104 is intermediate between D and E on the outer peripheral surface of the rotating member 7. The position is the same as in FIG. 8 (c), but in FIG. 8 (c), it is in contact with the floor surface at a position closer to D, which is different from the portion in contact with the floor surface. . Thereafter, the above-described operations are sequentially repeated.

  10 and 11 show a second embodiment according to the present invention. Here, the two rotation control devices P and P ′ are arranged in series by connecting the shaft members 5 and 5 ′ to each other by pin joints, and assembled to the one end side of the roller body 104 ( FIG. 11). Here, as shown in FIG. 10, the rotation reference position of the rotation member 7 ′ of the second rotation control device P ′ is the rotation reference position of the rotation member 7 of the first rotation control device P (the position A is shown in the figure). For example, a phase difference of 36 degrees is provided with respect to the uppermost position. By doing so, the resolution of the rotation angle of the roller body 104 ′ becomes a half angle of about 36 degrees. Note that these two rotation control devices P and P ′ may be assembled separately on both ends of the roller body 104 ′. Although the case where two rotation control devices are provided has been described here, it is also possible to provide two or more rotation control devices.

Next, an example of use and operation in the second embodiment will be described with reference to FIG.
First, in FIG. 10A, in the first rotation control device P, the rotation member 7 represented by the half body 7A is placed at the rotation reference position, and the needle 13 is engaged with the first direction rotation prevention portion 15b. It is in a stopped state. Further, in the second rotation control device P ′, the rotation member 7 ′ is positioned at the rotation reference position that is shifted in phase by about 36 degrees with respect to the rotation member 7, and the needle 13 ′ has the first direction rotation allowance groove. It is in the process of moving within 15a ′. From such a state, the suction mouthpiece 101 ′ is moved in the forward direction (left direction in the figure) to perform wiping and cleaning.

  Then, as the roller body 104 ′ rotates, the rotating members 7 and 7 ′ rotate counterclockwise in FIG. 10, but the second direction rotation allowance groove 16a of the rotation control device P has a short distance, so 13, the roller body 104 ′ is allowed to rotate counterclockwise only to an angle of about 18 degrees. As shown in FIG. 10 (b), the needle 13 of the rotation control device P is engaged with the second-direction rotation blocking portion 16b at this position to block the rotation of the roller body 104 'in the counterclockwise direction. Then, as shown in FIG. 10 (b), the needle 13 is attracted in the direction toward the shaft member 5 along the second direction rotation preventing portion 16b by the biasing force of the spring member 12, and the second direction rotation preventing portion. It is locked at a position closest to the shaft member 5 of 16b. At this time, the needle 13 'of the second rotation control device P' is still in the process of moving within the first direction rotation allowance groove 15a '. Accordingly, the wiping material 103 ′ of the roller body 104 ′ is prevented from rotating by the needle 13 and the second direction rotation blocking portion 16 b in the first rotation control device P being locked, and FIG. In the middle, between C and D on the outer peripheral surface of the rotating member 7 and in contact with the floor surface at a position close to C (position between C 'and D' on the outer peripheral surface of rotating member 7 'and closer to D') In this state, wiping and cleaning are possible.

  Further, from this state, the suction mouthpiece 101 ′ is moved in the backward direction (right direction in the figure) to change the wiping surface of the wiping material 103 ′, and the roller body 104 ′ is moved clockwise (right direction in the figure). When the angle is rotated by about 54 degrees, as shown in FIG. 10C, in the first rotation control device P, the needle 13 is moving in the first direction rotation allowance groove 15a, and the second rotation control is performed. In the device P ′, the needle 13 ′ is in a state of being locked to the first direction rotation preventing portion 15b ′. Then, the needle 13 ′ is attracted in the direction toward the shaft member 5 ′ along the first direction rotation preventing portion 15b ′ by the urging force of the spring member, and the most shaft member 5 ′ of the first direction rotation preventing portion 15b ′. Lock in position.

  From this state, if the suction mouthpiece 101 'is moved again in the forward direction (left direction in the figure) to attempt wiping and cleaning, the roller body 104' will be counterclockwise (left direction in the figure) at an angle of about 18 degrees. Rotate to stop. At this time, as shown in FIG. 10 (d), in the first rotation control device P, the needle 13 is in a state of moving in the first direction rotation allowance groove 15a, but in the second rotation control device P ′. The needle 13 ′ is in a state of being engaged with the second direction rotation preventing portion 16b ′. Then, the needle 13 ′ is attracted in the direction toward the shaft member 5 ′ along the second direction rotation preventing portion 16b ′ by the urging force of the spring member, and the most shaft member 5 ′ of the second direction rotation preventing portion 16b ′. Lock in position. Accordingly, the roller body 104 ′ is positioned between D ′ and E ′ on the outer peripheral surface of the rotating member 7 ′ in FIG. 10 (d) and closer to D ′ (the positions of C and D on the outer peripheral surface of the rotating member 7). It touches the floor surface at a position close to D in the middle and can be wiped and cleaned in this state.

  Further, when the roller body 104 ′ rotates clockwise by 54 degrees from this state, as shown in FIG. 10E, in the first rotation control device P, the needle 13 is locked to the first direction rotation preventing portion 15b. In the second rotation control device P ′, the needle 13 ′ is engaged with the first direction rotation allowance groove 15a ′, and the above operation is repeated. By doing so, the resolution of the rotation angle of the roller body 104 ′ can be set to a half angle of 36 degrees.
