Abstract

PROBLEM TO BE SOLVED: To prevent slack of wiping cloth caused by unintentional rotation of an upper rotation body.SOLUTION: The cleaning tool for building changes a wiping surface of wiping cloth by sequentially feeding the wiping cloth from an upper rotation body to a lower rotation body. The lower rotation body has a cross sectional shape where the center of gravity is displaced vertically. The upper rotation body is rotatable in linkage with the take-up action of the lower rotation body or manually. When the lower rotation body wipes a wiping target surface with the wiping cloth, free rotation of the upper rotation body is inhibited by either locking means or ratchet means, disposed at the upper rotation body. On the other hand, when a predetermined amount or more of rotation torque is applied to the upper rotation body from the lower rotation body via the wiping cloth in changing the wiping surface of the wiping cloth, locking of the locking means is released, or locking of the ratchet means is released by pulling manually the upper rotation body in the axial direction.

Description

  The present invention relates to a building cleaning tool for wiping a floor surface or a wall surface of a building. For example, the floor of the building is grasped by a handle such as a bar, a frame, or a T-shape, and a wiping cloth corresponding to a cloth is operated back and forth. The present invention relates to a building cleaning tool that can easily clean a surface.

Patent Document 1 states that “a hole is provided at the center of both ends of a wiping body in the form of a horizontal triangular prism, and a square-shaped support shaft is inserted into the hole, and a handle is provided at the top of the support shaft, "Triangular mop for cleaning" using three surfaces of the outer periphery of the wiper by rotating the "wiping body" is disclosed.
Since this patent document 1 can each use three surfaces of the outer periphery which is a stop surface of a wiping body when wiping a dirty floor surface, the outstanding effect that the frequency | count of washing a dirty cloth can be reduced can be used. However, since the structure is only a mop type, for example, there is a problem that the wiping surface of the long wiping cloth cannot be sequentially changed with respect to the wiping surface of the wiping body (the surface contacting the floor surface). It was.

  Patent document 2 is “a cleaning tool that sequentially changes the wiping surface by sending the wiping cloth F, and is located on the front side of the handle member 2, the polygonal column-shaped wiping base 30, and the handle member; A first holding member 20 that can hold the wiping cloth F; and a second holding member 25 that is positioned on the back side of the handle member and that can hold the wiping cloth F. The handle member 2 is attached in the vicinity of the distal end of the handle member so that the shaft is substantially perpendicular to the extending direction of the handle member 2 and is rotatable about the column shaft. The first guide 6 and the second guide 7 extend, and the first holding member 20 extends substantially parallel to the wiping base 30 and is slidable along the first guide 6. The second holding member 25 extends substantially parallel to the wiping cloth base 30. Both slidable cleaning implement "is disclosed along second guide 7 (numerals in Patent Document 2).

  This patent document 2 can solve the problem of patent document 1, and can send the wiping cloth F one by one and can change the wiping surface. However, the wiping cloth F has a predetermined length such as a towel, and the wiping surface of the wiping cloth F is changed by displacing the first holding member 20 in the upward direction of the handle member 2. The dirty wiping surface after wiping the floor surface is always exposed on the front side of the wiping table 30 and the appearance is not good. The dirt is removed from the wiping surface, the length of the wiping cloth F and the wiping surface. There is a problem that the range is limited to the range of the vertical movement of the sleeve member 9 that guides the string-like connecting member 35.

  Patent Document 3 discloses an upward U-shaped base plate (base body) 1 having a horizontal floor 2 and a pair of front and rear vertical banks 3 and 3 provided at a front end and a rear end of the horizontal floor. A front winding shaft that is disposed on the front surface of the front vertical bank portion 3 of the base plate 1 and winds one end of the roll-shaped wiping cloth; A rear feed shaft that is disposed on the inner surface side of the bank portion 3 and winds the other end portion side of the wiping cloth, located above a substantially central portion of the horizontal floor portion 2 of the base plate 1, A frame-shaped presser member that simultaneously presses both the upper outer periphery of the wiping cloth wound on the front winding shaft and the upper outer periphery of the wiping cloth wound on the rear feed shaft. "A cleaning tool" is disclosed (reference numeral 3).

  Although this patent document 3 is provided with the front winding axis | shaft and the back delivery axis | shaft (a total of two wiping axis | shafts), although it has the advantage that a roll-shaped wiping cloth can be used, wiping cloth The wiping area becomes larger than necessary, the frame-shaped presser member must be operated during wiping, and the roll-shaped wiping cloth must be fixed. There were problems such as being necessary, troublesome to change the wiping surface of the wiping cloth, and troublesome to set the wiping cloth.

The main purpose of the present invention is that the wiping body changes to potential energy depending on the rolling position (in the present invention, the rotation of the lower rotating body during wiping is prevented) and the wiping cloth is used when operating the handle. The advantage of Patent Document 2 that prevents sagging by a locking mechanism (in the present invention, prevention of rotation of the upper rotating body during the operation of the handle), and other handle that only requires an operating force to slide the lower rotating body during cleaning As a core material, while gaining advantages such as preventing the upper rotating body from rotating in the direction of sending out the wiping cloth by the pulling force of the wiping cloth partially wrapped around the lower rotating body during the pulling operation A wide area can be easily cleaned while winding the contact surface of the lower rotary body of the lower rotating body continuously, without changing the fabric during cleaning, or without removing the fabric from the core. It is that it is. In addition, the wiping cloth can be used to the maximum extent as a rag until the end of the rotation of the wiping cloth wound around the upper rotating body.
The second object of the present invention is not only to change the potential energy when the handle is operated back and forth, but also to the lower part as long as a predetermined rotational torque is not applied to the lower rotating body by the locking mechanism (including the friction mechanism). It is to prevent the rotating body from rotating easily. In addition, the wipe should be able to be sent out easily. Another object is that when the constituent elements of the dependent claims are added to the structure of claim 1, for example, the upper rotating body of the wiping cloth can be easily detached from the support body, and the upper rotating body is wound in a roll shape. It is an object of the present invention to use the mounted wiping cloth to the extent that the upper rotating body can rotate, to reliably prevent sagging of the unwrapped portion of the wiping cloth, and the like.

  The building cleaning tool of the present invention is a lower rotating body that has a plurality of horizontal contact surfaces that are pivotally supported on the lower end side of the support via a lower horizontal axis and that selectively come into surface contact with the surface to be wiped.

A cleaning tool for a building that sequentially changes the wiping surface of the wiping cloth by sending the wiping cloth from the upper rotating body to the lower rotating body, and the center of gravity of the lower rotating body is in the vertical direction. The upper rotating body can be rotated in conjunction with the winding operation of the wiping cloth, and the lower rotating body wipes the surface to be wiped with a wiping cloth. Sometimes, the upper rotating body is prevented from freely rotating by the locking means provided on the upper rotating body. On the other hand, when changing the wiping surface of the wiping cloth, the engagement of the locking means is released when a rotational torque of a predetermined level or more is applied from the lower rotating body to the upper rotating body via the wiping cloth. (Claim 1).

  Further, the building cleaning tool of the present invention is a lower rotation having a plurality of horizontal contact surfaces that are pivotally supported on the lower end side of the support body via the lower horizontal axis and selectively come into surface contact with the surface to be wiped. An upper rotating body that is pivotally supported via a horizontally long cylindrical upper horizontal axis that is integrally provided on the upper end side of the support body with a required gap with respect to the lower rotating body, A cleaning tool for a building comprising a handle provided on an upper wall portion of the support, and sequentially changing the wiping surface of the wiping cloth by sending the wiping cloth from the upper rotating body to the lower rotating body. The lower rotating body has a cross-sectional shape whose center of gravity is displaced in the vertical direction, and the upper rotating body can be rotated in conjunction with the winding operation of the wipe, and the lower rotating body is When wiping the surface to be wiped with a wiping cloth, one locking means provided on the upper rotating body The free rotation of the upper rotating body is prevented by the other engaging means that engages with the one locking means, and when the wiping surface of the wiping cloth is changed, the horizontally long cylindrical upper horizontal shaft The operation end portion of the long rod-shaped operation rod that is fitted in the penetrating state and has the other engagement means and protrudes from one side wall of the support body against the urging force of the urging means When pushed, the engagement between the other engagement means and the one locking means is released, and the upper rotating body can feed out the wiping cloth (Claim 5).

  Further, the building cleaning tool of the present invention is a lower rotation having a plurality of horizontal contact surfaces that are pivotally supported on the lower end side of the support body via the lower horizontal axis and selectively come into surface contact with the surface to be wiped. A body, an upper rotating body pivotally supported on the upper end side of the supporting body via an upper horizontal axis with a required gap with respect to the lower rotating body, and an upper wall portion of the supporting body. A cleaning tool for buildings that changes the wiping surface of the wiping cloth by sequentially sending the wiping cloth from the upper rotating body to the lower rotating body, and the center of gravity of the lower rotating body is in the vertical direction. The upper rotating body includes ratchet means composed of ratchet teeth and engaging claws, and when the lower rotating body wipes the surface to be wiped with a wiping cloth, the ratchet means The upper rotating body is completely prevented from rotating, while the wiping cloth is wiped off. When changing the surface, the upper rotating body is displaced in the axial direction against the biasing force of the biasing means, so that the engagement state between the ratchet teeth and the engaging claws is released, and the upper rotation The body can be freely rotated (claim 6).

  Furthermore, the building cleaning tool of the present invention has a plurality of horizontal contact surfaces that are pivotally supported on the lower end side of the support via a lower horizontal axis and selectively come into surface contact with the surface to be wiped. A rotating body, an upper rotating body pivotally supported on the upper end side of the support body via an upper horizontal axis with a required gap with respect to the lower rotating body, and an upper wall portion of the support body A cleaning tool for a building that sequentially changes the wiping surface of the wiping cloth by sending the wiping cloth from the upper rotating body to the lower rotating body. The upper rotating body has one engaging means provided on the support side and the other engaging means detachable, and the lower rotating body is wiped with a wiping cloth. When wiping the surface to be removed, the upper rotating body is completely rotated by the engagement state of the both engagement means. On the other hand, when changing the wiping surface of the wiping cloth, the upper rotating body is displaced in the axial direction against the urging force of the urging means, thereby engaging the engagement means of the two. The state is released, and the upper rotating body can be freely rotated (claim 7).

  In the above configuration, in order to prevent sagging of the unwrapped portion of the wiping cloth positioned between the upper rotating body and the lower rotating body on the support, a fingertip shape that presses the outer surface of the unwrapped portion or A “sag prevention means” provided with a pressing body formed in any one of horizontal bars is provided (claim 8). Preferably, the sagging prevention means includes a pair of left and right projecting arms each having a base end pivotally supported by a support, and upper and lower ends connected to the projecting portions of the distal end portions of these projecting arms. Alternatively, a pair of left and right support bars oriented in the tilt direction, a pair of left and right fitting cylinders fitted to the upper end side of these support bars, and rotatably supported by these fitting cylinders, A pressing part formed directly on the fitting cylinder that presses the unwrapped part of the wiping cloth either in a point, finger-like or substantially horizontal line, or a pressing body separate from the fitting cylinder; The one end is attached to the support, the other end is attached to the tip end side of the protruding arm, and the upper end side of the support bar is slidably inserted into the lower end of the fitting tube, A second urging force is provided between the lower end of the fitting tube and the protruding portion of the tip of the protruding arm. When the surface to be wiped is wiped with the lower rotating body, the tip of the protruding arm is displaced to the unwrapped part side of the wipe by pushing down the handle to the surface to be wiped. And the upper end side of the support rod further enters the lower end portion of the fitting tube against the urging force of the second urging means in correspondence with the position displacement amount. It comprises a pair of left and right first urging means for urging in the direction of the non-winding part (claims 9 and 10). Further preferably, the upper end portion side of the support rod is slidably fitted into the lower end portion of the fitting cylinder, and the second urging means is interposed between the lower end portion of the fitting cylinder and the protruding portion of the tip end portion of the protruding arm. When the surface to be wiped is wiped with the lower rotating body, the tip end side of the protruding arm is displaced to the unwrapped portion side of the wiping cloth by pushing down the handle toward the surface to be wiped. The upper end portion side of the support rod further enters the lower end portion of the fitting cylinder against the urging force of the second urging means corresponding to the position displacement amount (claim 11).

(A) According to the first aspect of the present invention, since the external shape of the lower rotating body as the wiping body is shaped so as to change to potential energy depending on the rolling position, it does not rotate easily even if the handle is operated back and forth. In addition, since the vertical cross-sectional shape of the lower rotating body is such that the axis (center of gravity) of the lower horizontal axis of the lower rotating body moves up and down, it does not rotate easily. Moreover, since the upper rotating body includes a locking mechanism, the upper rotating body does not rotate carelessly and the wiping cloth does not sag. In addition, there is an effect that an operation force that slides only the lower rotating body is sufficient at the time of cleaning, and that the wiping cloth can be used to the maximum extent until the end of rotation of the wiping cloth wound around the upper rotating body. . In addition, while continuously winding the contact surface of the lower rotating body as the core material, cleaning, changing the extracted fabric, or removing the extracted fabric from the core material, it is easy to cover a wide area. Can be cleaned.
(B) In the invention according to claim 2, since the lower rotating body is provided with the locking means similarly to the upper rotating body, the lower rotating body does not rotate easily. However, since it is desirable to operate the handle forward and backward, it is desirable that the locking means of the lower rotating body is in an engaged state in which a friction or click state is obtained.
(C) The invention according to claim 3 obtains the effect of (a) above because the outline of the cross-sectional shape of the lower rotating body is one of a substantially regular triangle, a substantially regular square, and a substantially track shape. This is the most desirable embodiment.
(D) In the invention described in claim 4, since at least the upper horizontal shaft is horizontally mounted so as to be removable from the support body, the upper rotating body of the wipe wrapping can be easily detached from the support body. . Of course, in the case of the embodiment in which the lower rotating body can be detached from the support in the same manner as the upper rotating body, the dirty wiping cloth can be easily washed.
(E) The invention described in claim 5 has the same effect as that of the invention described in claim 1, and when the wiping cloth wound around the upper rotating body is sent out, the operation end of the operation rod Is pushed against the urging force of the urging means, the engagement of the engaging means for the upper rotating body is easily disengaged, so the upper rotating body can be turned while maintaining the disengaged state. The body wipes can be sent out easily.
(F) According to the invention described in claim 6, since the external shape of the lower rotating body as the wiping body is shaped so as to change into potential energy depending on the rolling position, it does not rotate easily even if the handle is operated back and forth. In addition, the vertical cross-sectional shape of the lower rotating body does not rotate easily because the axis (center of gravity) of the lower horizontal axis of the lower rotating body moves up and down. Further, since a means (for example, a ratchet means) for completely preventing the rotation of the upper rotating body when the handle is pulled is provided, the wiping wound around the upper rotating body not only during cleaning but also during transportation. The cloth does not sag at all. In addition, the wiping cloth can be used to the maximum extent as a dust cloth until the end of the rotation of the wiping cloth wound around the upper rotating body.
(G) In the invention according to claim 7, when the upper rotating body is pulled in the axial direction against the urging force of the urging means, one of the engagements provided integrally with the support corresponding to the fixed member. Since the ratchet teeth (35A) as the other engaging means integrally provided via the bearing to the outer cylinder as the movable side member are separated from the engaging claw (34B) as the coupling means, the outer cylinder is The wiping cloth can be sent out while being pulled. In addition, there are the same effects as those of the first aspect of the invention.
(H) In the inventions according to claims 8 to 10, the outer surface of the unwrapped portion of the wiping cloth is directed toward the inner surface by the fingertip-shaped pressing portion or the horizontal bar-shaped pressing body of the sagging prevention means. For example, even if the handle is tilted forward and the unwrapped portion of the wiping cloth sag in a curved shape, it is possible to reliably prevent “sagging” of the unwrapped portion of the wiping cloth. it can. Further, when the pressing body is preferably in the form of a horizontal bar, the outer surface of the unwrapped portion of the wiping cloth can be pressed in a substantially uniform state from the horizontal end to the horizontal other end.
(I) The invention according to claim 11 can give sufficient tension to the unwrapped portion y of the wiping cloth even if the unwrapped portion y of the wiping cloth “sags in a curved surface” inside. That is, when the handle is pushed down in the floor direction, the tip end side of the protruding arm is displaced to the unwrapped part side of the wiping cloth, and the upper end side of the support bar is the first side corresponding to the position displacement amount. 2 Since it enters further into the lower end part of the fitting cylinder against the urging force of the urging means, a sufficient tension can be applied to the unwrapped portion of the wiping cloth.

  1 to 12 show a first embodiment of the present invention. In these drawings, X is a building cleaning tool used when wiping dirt on the surface to be wiped such as a floor surface, a wall surface, and a glass surface of a building, and 1 is a support (support portion) constituting a handle member. ) 2 is a handle constituting the handle member, 3 is a lower horizontal shaft pivoted on the lower end side of the support body (support portion) 1 of the handle member, and 4 is a lower rotating body provided on the lower horizontal shaft 5 is a required gap, 6 is an upper horizontal shaft pivoted on the upper end side of the support 1, 7 is an upper rotating body provided on the upper horizontal shaft, and 8 is provided on the lower rotating body. A lower fixing means 9 is an upper fixing means provided on the upper rotating body. 1 is a front view and FIG. 2 is a right side view. Here, a basic configuration aspect of the embodiment will be described with reference to a perspective view of FIG. 8 (basic configuration aspect in design).

  The entire building cleaning tool X has a bar-like handle 2 provided vertically at the center of the upper wall portion 1a of the downwardly "U" -shaped support 1, and the left and right ends of the upper wall 1a of the support 1 A lower triangular rotating body 4 having a substantially triangular prism shape is provided on the lower end of a pair of support arms 1b and 1b that are provided below the lower rotating body 4 via a lower horizontal shaft 3 so that the wiping cloth can rotate with respect to the lower rotating body 4. A substantially cylindrical upper rotating body 7 is horizontally arranged in parallel with an upper side shaft 6 on the upper end side of the pair of support arms 1b and 1b with a required gap 5 therebetween.

  The basic configuration aspect described above is a novel appearance configuration as a design itself. The technical idea inherent in the basic configuration aspect is as follows. That is, the building cleaning tool X of the present invention is “a plurality of horizontal supports that are pivotally supported on the lower end side of the support 1 via the lower horizontal shaft 3 and are in surface contact with the surface F to be wiped selectively. The lower rotating body 4 having contact surfaces 4a, 4b, and 4c, and the lower rotating body is pivotally supported via the upper horizontal shaft 6 on the upper end portion side of the support body 1 with a required gap 5. The upper rotating body 7 and the handle 2 provided on the upper wall portion 1a of the support 1 are provided, and the wiping cloth Y is sequentially sent from the upper rotating body 7 to the lower rotating body 4 to wipe the wiping cloth. Change the surface "(see, for example, FIG. 3).

  Therefore, the appearance of the support 1 is downwardly “U” -shaped, the handle 2 is rod-shaped, the appearance of the lower rotator 4 is a substantially triangular prism, and the appearance of the upper rotator 7 is substantially the same. The internal structure of the lower rotator 4 and the upper rotator 7 is a matter that can be arbitrarily changed in design without departing from the problem of the invention. In other words, for example, the upper wall 1a of the support 1 is formed into a roof shape, the upper end corresponding to the grip portion of the handle 2 is formed into a “T” shape, and the lower end corresponding to the attachment base end of the handle 2 is formed. Bifurcated, handle 2 is foldable, handle 2 is split, handle 2 is telescopic, and the outer shape of the lower rotating body 4 is not a polygon but an appropriate oval shape. Even if the design of the outer shape of the rotating body 7 is changed to a substantially polygonal shape instead of a substantially cylindrical shape, it is included in the technical scope of the present invention as long as the object of the present invention can be achieved.

  The basic concept of the present invention is as follows. That is, the building cleaning tool X pushes and pulls the handle forward and backward with both hands at the upper end of the handle 2 extending to the vicinity of the chest of the adult, for example, when cleaning a so-called rag. Therefore, it is useless if the lower rotating body 4 is easily rotated by the operating force of the handle. Therefore, in order to prevent the lower rotating body 4 from easily rotating, it corresponds to the distance from the central axis in the cross-sectional shape to one point corresponding to the central portion of the horizontal contact surface of the cross-sectional shape and the end portion of the horizontal contact surface. The distance to another point is different. Such a concept is a known matter as disclosed in Patent Document 1 and Patent Document 2. However, according to the present invention, with the known matter as a specific matter, an upper rotating body 7 provided with a locking means (including friction means) is further provided between the left and right support arms of the support 1, for example, the upper rotation In the body 7, the lower rotating body 4 can be rotated in conjunction with the winding operation of the wiping cloth Y (first embodiment), or the upper rotating body 7 can be wiped by a ratchet means during transportation or cleaning. The ratchet of the ratchet means does not rotate at all in the feeding direction, and is displaced in the axial direction against the urging force of the urging means only when the wiping cloth is wound up by the lower rotator. Each is characterized in that the engagement state between the teeth and the engaging claws is released and the upper rotating body can be freely rotated (second embodiment) (feature point 1).

  In addition, there are the first embodiment in which the upper rotating body 7 is provided with the locking means and the two inventions in which the upper rotating body 7 is provided with the ratchet means. The problem of the invention is common in the point of preventing rotation.

  Therefore, an example of an embodiment of the present invention will be described in detail with reference to FIGS. 3, 4, 5, and the like. First, the configuration of the lower rotating body 4 will be described.

  In these drawings, 1b and 1b are a pair of left and right support arms each having a circular shaft hole 11, and one of these support arms, in the embodiment, the left support arm (side plate) 1b has an inner surface facing sideways. A recessed fitting portion 12 is formed, and the recessed fitting portion 12 communicates with the circular shaft hole 11. Reference numeral 13 denotes a lower locking means comprising a fixed-side male 14 and a movable-side female 15. In the embodiment, the locking means 13 has a so-called clutch function, click function or brake function. For example, one support arm 1b and the bearing of the lower rotating body 4 (one on the side facing the locking means 13). Of the bearing portion 16a) 16.

  Thus, the fixed-side male 14 is formed in a vertical disk shape having an unnumbered shaft hole in the center, and is fitted to the recessed fitting portion 12 of the left support arm 1b on one side surface thereof. An angular shaft-like fitting portion 14a is formed so as to protrude. On the other hand, a plurality of (for example, three) engaging protrusions 14b are provided on the other side surface of the fixed-side male 14 with a predetermined interval in the circumferential direction. Accordingly, the male shaft 14 of the locking means 13 becomes an engaging member on the fixed side or the non-rotating side when the angular shaft-shaped fitting portion 14a is fitted into the recessed fitting portion 12 of the left support arm 1b. .

  The movable side female 15 is also formed in a disk shape like the fixed side male 14, but as a whole is a vertical / thick annular member, with a slightly larger diameter at the center. A perfect circular fitting hole 15a is formed. A plurality of (for example, three) engagement holes 15b that are engaged with and disengaged from the fixed-side engagement protrusions 14b are appropriately formed on one side of the male 14. The “number” of the engagement protrusions 14 b and the engagement holes 15 b is not particularly limited, but is set appropriately in consideration of the rotational force of the lower rotating body 4.

  In the embodiment, the bearing 16 having an unnumbered shaft hole is formed as “one” as a sideways substantially triangular prism, but of course, it is a pair of substantially triangular bearings 16 a and 16 b facing left and right. Also good. Here, as shown in FIG. 6, the left bearing part facing the movable knife 15 is denoted by reference numeral 16 a, and the right bearing part on the opposite side is denoted by reference numeral 16 b for distinction.

  On the end surface of the left bearing portion 16a, a perfect circular short cylindrical fitting portion 17 is formed to protrude substantially at the center, and a predetermined interval in the circumferential direction so as to surround the outer peripheral surface of the short cylindrical fitting portion 17 A plurality of (for example, three) short engagement rods 18 are fixedly provided. The short cylindrical fitting portion 17 of the bearing portion 16a is fitted into the fitting hole 15a of the movable knife 15, and at the same time, the short engagement rod 18 of the bearing portion 16a is wound with a female biasing means 19, respectively. In this state, it engages with the engagement hole 15b of the movable knife 15. Therefore, the movable-side knife 15 cooperates with the bearing 16 constituting the lower rotating body 4 via the engagement hole 15b and the short engagement rod 18.

  Reference numeral 20 denotes a substantially triangular cylindrical outer cylinder which is located between the left and right support arms 1b and 1b and is fixedly fitted to the bearing 16 described above. The outer cylinder 20 has a substantially triangular cylindrical shape. The male 14 and the female 15 of the engaging means 13 and the bearing 16 are incorporated in a state in which the lower horizontal shaft 3 is passed through the inside. The lower horizontal shaft 3 is rotatably mounted horizontally on the left and right support arms 1b and 1b. For example, the left and right support arms are formed by a male screw portion 21 formed at an end portion and a small nut 22 screwed into the male screw portion. It is configured to be removable from 1b and 1b. Reference numeral 23 denotes a bearing biasing means, and the bearing biasing means is wound around a portion near the end of the lower horizontal shaft 3 so as to be positioned between the right bearing portion 16b and the right support arm (right wall) 1b. Has been. The bearing urging means 23 urges the right bearing portion 16 b in the direction of the locking means 13 so that the right bearing portion 16 b does not protrude from the right end edge of the triangular cylindrical outer cylinder 20. In addition, since the internal structure of the lower rotary body 4 is only an example, you may employ | adopt the internal structure of the upper rotary body 7 demonstrated below. Therefore, the design of the lower locking means 13 can be arbitrarily changed.

  Next, the configuration of the upper rotating body 7 will be described with reference to FIGS. 3, 5, and 7. The upper rotating body 7 is provided with an upper locking means 33 in one side wall 1b of the support 1 or inside the upper rotating body 7 in order to solve the problem of “preventing sagging of the wiping cloth Y”. The structure of the upper locking means 33 is slightly different from that of the lower locking means 13 as is apparent from, for example, comparing FIGS. 6 and 7, but the basic concept (preventing free rotation) is the same. Therefore, the same part uses the same term and omits the overlapping description. Therefore, the design of the upper locking means 33 can be arbitrarily changed in the same manner as the lower engaging means 13.

  In these drawings, 1b and 1b are left and right support arms of the support, 6 is an upper horizontal axis, 31 is a shaft hole formed in the support arms 1b and 1b, and 32 is an inner wall surface of the left support arm 1b. A plurality of guide rods fixedly provided, 33 is an upper locking means comprising a male 34 that can move horizontally and a knife 35 that rotates together with the bearing 36, and 40 is fixedly fitted to the bearing. The outer cylinder, 39 is a male biasing means, and 43 is a bearing biasing means.

Thus, a plurality of (for example, two) guide rods 32 are fixed in the horizontal direction on the inner wall surface of the one (left side) support arm 1b. On the other hand, a plurality of (for example, two) guide grooves 34a into which the guide rod 32 is engaged are formed on one side surface of the male 34 having an unnumbered shaft hole, and a plurality (for example) are formed on the other side surface on the opposite side. For example, three engagement protrusions 34b are provided.
Accordingly, the male 34 of the upper locking means 33 does not rotate because the guide bar 32 of the left support arm 1b is engaged with the guide groove 34a, and resists the urging force of the urging means 39 at that position. Thus, it can move backward toward the inner wall surface of the left support arm 1b. In this respect, the lower locking means 13 is slightly different.

  However, the knife 35 is formed in a disk shape like the movable knife 15 on the lower side, and is a vertical / thick annular member as a whole. A slightly large-diameter perfect circular fitting hole 35a is formed in the central portion, and a plurality of (for example, three) engaging holes that engage with and disengage from the male engaging protrusion 34b are formed on one side surface thereof. 35b is appropriately formed. Although the “number” of the engagement protrusions 34 b and the engagement holes 35 b is not particularly limited, the point is set appropriately in consideration of the rotational force of the upper rotating body 7, as in the lower rotating body 4. In addition, the configuration of the short circular cylindrical fitting portion 37 and the short engagement rod 38 formed on the left bearing portion 36 a of the bearing 36 is the same as that of the lower bearing 16. In this embodiment, the protruding end of the upper horizontal shaft 6 is appropriately stopped by a stopper (for example, an E-ring) 50, but the upper horizontal shaft 6 is supported on the left and right sides in the same manner as the lower horizontal shaft 3. A horizontal shaft is rotatably mounted on the arms 1b and 1b.

  FIG. 9 is an explanatory diagram showing the external configuration (outer cylinder) of the main parts of the lower rotating body 4 and the upper rotating body 9. That is, 20 is an outer cylinder of the lower rotating body 4, 40 is an outer cylinder of the upper rotating body, and the fixing means 8 and 9 are provided in the lateral direction or the circumferential direction in each of the outer cylinders 20 and 40 as described above. ing. In addition, it is desirable to provide the fixing means 8 and 9 at the corners (ridge lines).

  Thus, the lower outer cylinder 20 has, for example, a total of three horizontal contact surfaces 4a, 4b, and 4c that selectively come into surface contact with the horizontal floor surface F, preferably each of the horizontal contact surfaces 4a, A lower fixing means 8 for fixing the outer end portion of the wiping cloth Y to 4b and 4c is provided. As the lower fixing means 8, for example, Velcro (registered trademark) can be used. The wiping cloth Y is a long cloth, the long cloth is wound around the upper rotating body 9 in a roll shape, and the fixed end provided on the outer peripheral surface of the outer cylinder 20 of the lower rotating body 4. Removably fixed to the means 8.

  FIG. 10 shows a use state in which the handle 2 is pushed to move the lower rotating body 4 in the forward direction. When used (cleaning), the center of gravity of the lower rotating body 4 is the axis of the lower horizontal axis 3. Therefore, if one horizontal surface 4a is in surface contact with the floor surface F through the wiping portion of the wiping cloth Y at the time of cleaning, the gravity (self-weight) of the lower rotating body 4 is directly below the center of gravity as indicated by an arrow. As long as the operating force (axial force) indicated by the arrow from the handle 2 does not exceed the ridge line of the front corner (left corner in the drawing) a of the lower rotating body 4, it is physically (vector If the handle 2 is pushed, for example, when the handle 2 is pushed, the operating force (axial force) becomes a frictional force, and the lower rotating body 4 slides in the direction of the arrow A. At this time, depending on the operating force of the handle 2 (increase in potential energy), the lower rotating body 4 tries to rotate counterclockwise and exceeds the ridge line of the front corner (left corner in the drawing) a. However, in the embodiment, since the lower rotating body 4 also includes the locking means 13 like the upper rotating body 7, when the lower rotating body 4 wipes the surface F to be wiped with the wiping cloth Y, The free rotation of the lower rotating body 4 is prevented by the locking means 13. FIG. 11 shows a use state in which the lower rotary body 4 is moved backward by pulling the handle 2. When the handle 2 is pulled, unlike the case where the handle 2 is pushed, the lower rotating body 4 tries to rotate clockwise and tries to exceed the ridge line of the rear corner (right corner in the drawing) b. However, in the embodiment, since the upper rotating body 7 includes the upper locking means 33 like the lower rotating body 4, even if the wiping cloth Y is pulled downward, the lower rotating body 4. Unless the rotational torque more than a predetermined value is applied to the upper rotating body 7 through the wipe Y, the upper rotating body 7 does not rotate in the clockwise direction due to the locking force of the upper locking means 33 acting. Therefore, even if the handle 2 is pulled, the wiping cloth Y does not sag. The present invention is particularly characterized in this point (inhibition of free rotation of the upper rotating body 7 although it is incomplete).

  FIG. 12 is an explanatory view of winding the wiping cloth Y by rotating the lower rotating body 4 clockwise. When changing the wiping surface of the wiping cloth Y in the wound state on the lower rotating body 4, it is necessary to apply a rotational torque of a predetermined level or more to the lower rotating body 4 using, for example, a step or using a hand. . When a rotational torque of a predetermined level or more is applied to the lower rotating body 4, in the embodiment, the engagement of the male and female of the upper and lower locking means (33, 13) is simultaneously released. The wiping cloth Y is wound up by a predetermined amount, while the upper rotating body 7 is linked to send out the wiping cloth Y by a predetermined amount.

  Therefore, when grasping specific matters of the invention from the relationship with the problem of the invention of “preventing sagging of the wiping cloth Y”, the upper locking means 33 among the upper and lower locking means (33, 13) is important. The lower locking means 13 is a dependent component.

  Next, another embodiment of the present invention will be described with reference to FIGS. In the description of other embodiments, the same parts as those in the first embodiment are denoted by the same or similar reference numerals, and redundant descriptions are omitted. Further, depending on the embodiment, the same or similar reference numerals are given to the same parts as those of the preceding embodiments, and redundant description is omitted.

  First, FIGS. 13 to 16 are explanatory views showing a second embodiment of the present invention. The main difference between the second embodiment and the first embodiment is that the subject of the invention is “preventing complete rotation of the upper rotating body 7 in the wiping cloth delivery direction”.

  In the first embodiment, the upper and lower locking means (33, 13) included in each rotating body (7, 4) is the engagement / disengagement of each male (14, 33) and each female (14, 34). At least the upper engagement / disengagement is performed by the “ratchet means 33A”. Note that ratchet means and locking means for engaging and disengaging below are not necessary.

  Accordingly, in the second embodiment, when the lower rotating body 4 wipes the surface F to be wiped with the wiping cloth Y, the upper rotating body 7A is provided by the upper ratchet means 33A provided on the support body 1 or the upper rotating body 7. On the other hand, when the wiping surface of the wiping cloth Y is changed, the upper rotating body is displaced in the axial direction against the urging force of the urging means, thereby the ratchet teeth 35A. And the engaging claw 34B are disengaged, and the upper rotating body can be freely rotated.

  13 is a sectional view similar to FIG. 5 of the second embodiment, FIG. 14 is a sectional view taken along line 14-14 of FIG. 13, FIG. 15 is a schematic explanatory view of ratchet teeth, and FIG. It is a schematic explanatory drawing over the one or a plurality of engaging teeth. Referring to FIG. 13, the locking claw 34 </ b> B constituting the ratchet means 33 </ b> A is disposed at a portion (left lower portion in the drawing) that is eccentric with respect to the upper horizontal shaft 6 (upper shaft hole 31 of the left support arm 1 b). By the urging force of the latching claw urging means 45 housed in the storage portion 44 of the left support arm 1b, the bearing 16a is always formed in an annular shape on the side surface of the bearing portion 16a (left in the drawing). The ratchet teeth 35A are urged to engage with each other.

  Incidentally, reference numeral 46 denotes a spring end support shaft that supports the outer end portion of the latching claw biasing means 45, and the spring end support shaft 46 is provided with a male screw that is screwed with a screw formed in the storage portion 44. It is the screwing body which has.

  In the second embodiment, the ratchet means 33A is formed on the side surface of the bearing portion 16a. However, the ratchet means 33A may be formed on one support arm (side wall) of the support 1 that is a fixed member. In this case, it is desirable that a lateral recess is formed in the one supporting arm, and ratchet means 33A is formed on the inner wall surface of the lateral recess, while one or more engaging / disengaging with the ratchet means 33A. A base end portion of an elastic engagement arm that has an engagement claw 34B and that displaces outward is integrally provided on the side surface of the bearing portion 16a.

  FIG. 17 is an explanatory view showing a third embodiment of the present invention, and shows that the upper horizontal shaft 6 is horizontally mounted so as to be removable from the left and right support arms 1b and 1b of the support. FIG. 18 is an explanatory view showing a fourth embodiment of the present invention, and shows that the handle 2 is detachably provided from the upper wall portion 1a of the support 1. Of course, the handle 2 may be integrally formed with the upper wall 1a of the support 1.

  FIG. 19 is an explanatory view showing a fifth embodiment of the present invention, and shows that the outline of the sectional shape of the lower rotating body 4A is a substantially square. On the other hand, FIG. 20 is an explanatory view showing a sixth embodiment of the present invention, and shows that the outline of the sectional shape of the lower rotating body 4B is an elliptical shape having a substantially track shape.

  Finally, FIG. 21 and FIG. 22 are embodiments (seventh embodiment) showing a design variation of the second embodiment of the present invention, and FIG. 21 is a cross-sectional view similar to FIG. Engaging teeth). On the other hand, FIG. 22 is a schematic cross-sectional explanatory view in which the upper rotating body 7 is moved in the axial direction in FIG. 21 to disengage the engaging claws 34B from the ratchet teeth 35A. For convenience of explanation, the reference numerals of “ratchet means 33A”, “engaging claw 34B”, and “ratchet teeth 35A” are the same as those in the second embodiment. The other symbols are those shown in FIG.

  In the seventh embodiment, (a) all of the ratchet means 33A are provided in the upper rotating body 7, and (b) a hook-like stopper 49 is provided at a portion near one end of the upper horizontal shaft 6, or The upper horizontal shaft 6 has a small diameter portion from one end portion to one end portion, and a large diameter portion from the one end portion portion to the other end portion. When the ratchet teeth 35A provided on the end face of the bearing 36 of the upper rotating body 7 are pulled away from the engaging claw 34B guided by the guide rod 32, the pulling is performed in the direction of arrow A in FIG. The engagement state between the engagement claw 34B on the support body which is one engagement means and the ratchet teeth 35A on the outer cylinder side which is the other engagement means is released. For example, the engagement claw 34B is connected to the stopper 49 or Received by the annular step surface 49 and stays in that position

  Therefore, the seventh embodiment has the same basic configuration as the first embodiment, but the upper rotating body 7 includes ratchet means 33A including ratchet teeth 35A and engaging claws 34B, and the lower rotating body 4 When the surface F to be wiped is wiped with the wiping cloth Y, the ratchet means 33A completely prevents the rotation of the upper rotating body 7 in the direction in which the wiping cloth Y is fed, while the wiping surface of the wiping cloth Y is wiped off. At the time of changing, the ratchet teeth 35A and the ratchet teeth 35A can be obtained by grasping the outer cylinder 40 of the upper rotating body 7 by hand and displacing the upper rotating body 7 of the bearing 16 in the axial direction against the urging force of the urging means 43. The engagement state with the engagement claw 34B is released, and the upper rotating body 7 is freely rotated in this state (see FIG. 22). Accordingly, when the lower rotating body 7 is rotated by a predetermined amount in the winding direction, the upper rotating body 7 is rotated by a predetermined amount in the feeding direction via the wiping cloth Y, and the wiping surface and the horizontal contact surface of the wiping cloth Y are selected. Will change.

  23 to 27 are explanatory views showing an eighth embodiment of the present invention. The subject of the eighth embodiment is that, for example, in the first embodiment, when the handle 2 is lowered from a predetermined angle to the surface F to be wiped, the outer peripheral surface of the upper rotating body 7 is behind the lower rotating body 4. Since there is a problem that the unwrapped portion of the wiping cloth Y sag in a curved shape by approaching the horizontal contact surface on the side, in order to solve this, the unwrapped portion y of the wiping cloth Y In other words, a kind of tension is applied to the outer surface.

  Therefore, the building cleaning tool X according to the eighth embodiment prevents sagging of the unwrapped portion y of the wiping cloth Y located between the upper rotating body 7 and the lower rotating body 4 on the support 1. The sag prevention hand Z stage includes a first urging means 51 having one end 51a attached to the support 1, and the other end 51b of the first urging means 51 directly. Or it is attached indirectly via a pair of left and right indirect holding members 52, 52, and the outer surface of the unwrapped portion y of the wiping cloth Y is directed toward the inner surface by the biasing force of the first biasing means 51. The bar-shaped or pipe-shaped pressing body 61 is not unwrapped with the wiping cloth when the bar-shaped or pipe-shaped pressing body 61 wipes the surface F to be wiped with at least the lower rotating body 4. The part y is pressed in a substantially horizontal contact state. Further, since the rod-like or pipe-like pressing body 61 is provided on the pair of left and right fitting cylinders 56 via the horizontal axis (horizontal axis) 57, the pair of left and right fitting cylinders 56, the pressing body 61 and the like are arranged in the left-right direction. Do not shake (do not rattle).

  The sagging prevention means Z of the embodiment is between the upper rotating body 7 having the upper locking means (33, 33A, 33B) and the idling lower rotating body 4 not having the lower locking means 13. The pipe-like pressing body 61 is indirectly attached to the left and right support arms 1b, 1b of the support body 1 via a pair of left and right indirect holding members 52, 52 so that the pipe-shaped pressing body 61 is positioned in a substantially horizontal state. Here, only "one indirect holding member 52" will be described.

  Thus, as shown in FIG. 26, for example, the indirect holding member 52 has a long plate-like projecting arm whose base end portion 53a is pivotally supported on the lower end portion of the support arm 1b of the support 1 via a horizontal axis. 53, a protruding portion 54 protruding in the shape of a horizontal short cylinder or a horizontal short rectangular column on the inner side of the distal end portion 53b of the long plate-like protruding arm 53, and a vertical or inclined direction in which the lower end portion is connected to the protruding portion. The supporting rod 55 that is oriented, the fitting cylinder 56 in which the pipe portion 56a on the lower end side is externally fitted to the upper end portion side of the supporting rod 55, and the inner side of the upper end portion 56b of the fitting cylinder 56 are integrated. The pipe-shaped pressing body 61 described above is rotatably supported on the fitting cylinder 56 via the horizontal shaft 57.

  In the embodiment, the second urging means (for example, a coil spring) 58 is provided between the lower end portion of the pipe portion 56a of the fitting cylinder 56 and the protruding portion 54 of the distal end portion 53b of the protruding arm 53. As shown in FIG. 24, when wiping the wiping target surface F with the lower rotating body 4, the distal end portion 53 b side of the protruding arm 53 is wiped by pressing the handle 2 toward the wiping target surface F. A position of the Y is unwound at the unwinding portion y side, and the upper end side of the support bar 55 is against the biasing force of the second biasing means 58 corresponding to the amount of the position displacement. It further enters the lower end of 56a. As a result, sufficient tension can be applied to the unwrapped portion y of the wiping cloth even if the unwrapped portion y is “curved in a curved shape” inside.

  In the embodiment, the above-described protruding portion 54 having a horizontal short columnar shape or a horizontal short rectangular column shape is fixedly provided at the distal end portion 53b of the protruding arm 53, and the upper surface of the protruding portion 54 is directed slightly obliquely upward. A support hole 59 is formed, and the lower end portion of the support bar 55 enters and is fixed to the support hole 59, and the coil spring as the second urging means 58 is wound around the support bar 55. Thus, the lower end portion is supported by the support hole 59. Further, although not a limiting requirement of the present invention, the pulley 60 is rotatably supported on the inner side of the projecting portion 54 having a horizontal short cylindrical shape or a horizontal short rectangular column shape via a support shaft.

  28 to 30 are explanatory diagrams showing a ninth embodiment of the present invention. Similarly to the eighth embodiment, the ninth embodiment also includes a sagging prevention means Z1. Thus, the main difference between the ninth embodiment and the eighth embodiment is the pressing body 61A constituting the sagging prevention means Z1. The pressing portion corresponding to the pressing body 61A is that a finger portion such as a thumb shape or an index finger shape is formed on the inner surface of each fitting cylinder 56 of the pair of left and right indirect holding members 52, preferably on the inner surface of the upper end portion thereof. . In the embodiment, the inner surface of the upper end portion 56b of each fitting cylinder 56 is formed as a thumb-like finger surface.

  Accordingly, the pressing body 61A presses the unwound portion y of the wiping cloth Y in a fingertip contact state when at least the lower rotating body 4 wipes the wiping target surface F. The pressing body 61A of the ninth embodiment presses the outer surfaces of the left and right end portions of the unwrapped portion y of the wiping cloth Y like a finger pressure. For example, each fitting tube 56 is formed with a pressing body 61 </ b> A that protrudes in the horizontal direction so that it can be pressed in the horizontal direction. As described above, the design of the pressing body 61A can be arbitrarily changed without departing from the scope of the invention. In the ninth embodiment, the pair of left and right fitting cylinders 56 are integrally connected by a horizontal shaft 57 so that the pair of left and right fitting cylinders 56 do not shake.

  31 to 33 are explanatory views showing a tenth embodiment of the present invention.

The end portion 65a, on the other hand, an E-ring as a stopper 50 is attached to the protruding end portion protruding from the other side wall 1b, (d) one locking means constituting the locking means 33B for the upper rotating body The inner end of a cylindrical bearing 36B in which 35b is integrally provided on the inner peripheral wall of the outer cylinder 40 On the other hand, the other locking means 34b that engages and disengages with the one locking means 35b is provided integrally with the outer peripheral wall of the long rod-shaped operation rod 65, or is integrally molded. The point provided on the inner end surface of the bowl-shaped portion 34B, and the one locking means 35b, for example, is a recess as an engagement recess formed at a predetermined interval in the circumferential direction, while the other The locking means 34b is a single or a plurality of small protrusions that can be engaged with and disengaged from the recess. (E) One locking means 35b on the upper rotating body side is connected to the other locking means on the long rod-like operation rod 65 side. The urging means 39B for engaging 34b is, for example, between the inner surface of one side wall 1b where the stopper 50 of the support is located and the outer end surface of the hook-shaped portion 34B of the long rod-shaped operation rod 65. Further, it is a point wound around the long rod-shaped operation rod 65.
