Description

  The present invention relates to a cleaning holder for gripping a wiping body such as a mop and a cleaning tool for gripping the wiping body, and more particularly, to a wiping body gripping portion having a short width direction as a main cleaning direction. The present invention relates to a cleaning holder in which a handle part is connected via a part and the wiping body is held on the bottom surface of the wiping body holding part, and a cleaning tool in which the wiping body is held by the cleaning holder.

  An operation handle (also simply referred to as “handle” or “handle”) of a cleaning tool is rotatably attached to a cleaning tool holder that holds a wiping body such as a mop through a joint. Japanese Patent Laid-Open No. 9-24896 (Patent Document 1) describes a wiping and cleaning tool in which an operation handle is attached to a base portion by a joint portion. Japanese Patent No. 298110 (Patent Document 2) describes a handle (handle). Describes a cleaning tool attached to the mop body via a joint.

  FIG. 28 is a perspective view of a wiping cleaner 100 which is a conventional cleaning tool described in Patent Document 1. As shown in FIG. The wiping and cleaning tool 100 includes a rectangular base 102, and an operation handle 106 is attached to the upper surface of the wiping cleaner 100 via a joint 104 for changing the direction. An elastic body 108 is attached to the bottom surface of the base portion 102, and the bottom surface is formed in a flat plate shape. A sheet-like cleaning body is wound around the elastic body 108 as a wiping body so as to cover the entire bottom surface, and the wiping cleaning tool 100 is configured. Therefore, the wiping and cleaning tool 100 can rotate the operation handle 106 by the joint portion 104 to freely change the handle floor surface angle θ. For example, by tilting the operation handle 106 in the direction opposite to the cleaning direction (traveling direction), a force is applied in the cleaning direction via the operation handle, and the front dust 110a is swept away by the front edge portion 108a as shown in the figure. It is possible. However, when the wiping and cleaning tool 100 is advanced, the front dust 110a is collected by the front edge portion 108a. However, since the bottom surface of the elastic body 108 is in full contact, it is not wiped off by this bottom surface. Similarly, when the wiping cleaner 100 is moved backward, the rear dust 110b is collected by the rear edge portion 108b of the elastic body 108 but is not wiped off the bottom surface of the elastic body 108. That is, even if the front edge portion 108a and the rear edge portion 108b are dirty, the bottom surface thereof is hardly dirty. If the front edge portion 108a and the rear edge portion 108b are dirty, the sheet-like cleaning body needs to be replaced. However, the sheet-shaped cleaning body must be replaced in spite of being dirty, which is inefficient and shortens the life of the sheet-shaped cleaning body.

  FIG. 29 is an explanatory view for explaining the action of the mop 130 which is a conventional cleaning tool described in Patent Document 2, and shows an improved product of the cleaning holder shown in FIG. As shown in (29A), as described above, the mop 130 is attached to the mop body 131 having the holding portion 117 via the joint 116 having the handle 113 having a ball joint. In the mop body 131, a non-woven sheet (not shown) is attached as a wiping body to the bottom surface 133 by a holding member (not shown) of the holding part 117, on the base body 132 having the corners 136. Furthermore, in order to solve the problem of the wiping cleaner 100 whose bottom surface is in full contact with the cleaning direction shown in FIG. 28, the mop 130 of FIG. 29 has a bottom surface 133 with a curved surface formed in the cleaning direction. That is, the bottom surface 133 in the cleaning direction is formed so that the central portion 133a contacts the floor and the both end portions 133b and 133c do not contact the floor. When the mop body 131 is moved in one cleaning direction (traveling direction) e as shown in (29B) from the stationary state shown in (29A), the mop body 131 faces the side surface 135A of the base body 132 downward. And inclined along the curved surface of the first half of the bottom surface 133. At this time, the front half curved surface of the bottom surface 133 tends to come into contact with the floor via the nonwoven fabric sheet, but when the front half curved surface is lifted from the floor due to the curvature, the front garbage 110a is taken into the front half curved surface, The nonwoven fabric sheet corresponding to the first half curved surface of the bottom surface 133 collects dirt. As shown in (29C), when the mop body 131 is moved in the other cleaning direction f, the mop body 131 faces the side surface 135B of the base body 132 downward, along the curved surface of the rear half of the bottom surface 133. Tilt. At this time, the second half curved surface of the bottom surface 133 tends to come into contact with the floor via the nonwoven fabric sheet, but when the second half curved surface floats from the floor surface due to the curvature, the rear dust 110b is taken into the second half curved surface, The nonwoven fabric sheet corresponding to the second half curved surface of the bottom surface 133 collects dirt. That is, in the wiping body gripping tool in which a curved surface is formed in the cleaning direction, the wiping body is a wiping sheet, and accordingly, there is an advantage that the wiping sheet can be used without replacement until the entire surface of the wiping sheet becomes dirty. Therefore, in the mop 130 of FIG. 29, the problem of the wiping cleaner 100 whose bottom surface is in full contact with the cleaning direction shown in FIG. 28 has been partially solved.

Japanese Patent Laid-Open No. 9-24896 Japanese Patent No. 2981110

In the wiping and cleaning tool 100 shown in FIG. 28, as described above, the operation handle 106 can be inclined by the joint portion 104, and the handle floor surface angle θ can be freely changed. For example, as shown in the figure, when the operation handle 106 is inclined to the rear side in the cleaning direction and the operation handle is pushed forward in the cleaning direction, the front dust 110a can be swept away by the front edge portion 108a. However, in this state, the base 102 is horizontally rotated in the direction of arrow s with respect to the floor surface. Therefore, when the operation handle 106 is twisted in the handle twisting direction r indicated by the arrow, the base 102 is horizontally rotated in the direction of arrow s. Instead, the base part 102 often reversed in the base part reversal direction t indicated by the arrow with the reversal axis m as a branch line. In particular, when the inclination angle θ is small, the inversion phenomenon tends to occur. That is, it is assumed that the base part 102 is inverted by the following action. A slight gap (so-called “play”) is provided at a connection portion (not shown) of the joint portion 104 with the operation handle 106. Even if the operating handle is twisted in the gap of this play, the torsional moment is not transmitted to the base part 102 only by receiving a rattling sound and a hand feeling of vibration. In other words, when the operation handle 106 is twisted, the operation handle 106 itself slightly rotates in the handle twisting direction r. However, within the slight rotation width of the operation handle 106 due to the “play”, the base portion 102 is used as a base. The torsional moment that rotates in the base rotation direction s is not acting. When the operation handle 106 is twisted beyond the slight rotation of the play, a torsional moment is suddenly applied to the base portion 102 from the operation handle 106. Therefore, the force vector is relatively large, and the front of the cleaning direction in FIG. To change in the longitudinal direction of the base 102. Therefore, a relatively large force acts in a striking manner, and the base portion 102 may act so as to be reversed in the base portion reversal direction t with the reversal axis m as a branch line. In other words, even if the operation handle 106 is twisted, it is difficult to apply a suitable couple that rotates the base portion 102 in the base portion rotation direction s. Further, from the viewpoint of the moment distance, the direction perpendicular to the longitudinal direction of the base portion 102 is the cleaning direction, and the central portion of the front edge portion 108a and the rear edge portion 108b has a distance from the operation handle that is the rotation axis. The moment distance is short because it is close, and the horizontal rotation moment in the direction of the arrow s is relatively small. On the other hand, since the moment distance from the operation handle to the edge in the longitudinal direction is relatively long, the reversal rotational moment in the direction of the arrow t is relatively large, and the base 102 is easily reversed. Therefore, it is difficult to horizontally rotate the base unit 102 in the direction intended by the user of the cleaning tool.
Further, when the “play” is not provided, it is difficult to smoothly change the handle floor surface angle θ, and the load applied to the joint portion 104 is increased. In some cases, the tool life could be shortened.

  The mop 130 shown in FIG. 29 is attached to the mop body 131 through a joint 116 having a handle 113 having a ball joint. This mop body 131 also tends to be inverted without rotating horizontally for the same reason as in FIG. Briefly, when the handle 113 is twisted and the mop body 131 is rotated, the handle 113 is similarly rotated by a predetermined angle by the ball joint. However, when it exceeds the play and rotates by a predetermined angle, the torsional rotational moment acts on the mop body 131 suddenly, the force vector is relatively large, it acts as a striking force, and changes from the cleaning direction to the longitudinal direction. Trying to. That is, a suitable couple that rotates the mop body 131 does not act. Further, the reversal rotational moment acting on the longitudinal end edge having a long distance from the operation handle as the rotation axis is large, and the base portion 102 is easily reversed. Therefore, the mop body 131 is often reversed, and it is difficult to rotate the mop body 131 horizontally with respect to the floor surface, that is, the direction intended by the user of the cleaning tool. It was.

  Accordingly, the first object of the present invention is to provide a cleaning holder that has good operability and can be easily and freely changed in direction by a user, and a cleaning tool using the same. It is a second object of the present invention to provide a cleaning holder that can use the wiping body gripped by the holding tool with high efficiency, achieve a long life by extending the replacement period of the wiping body, and a cleaning tool using the same.

This is a dynamic cleaning tool.

  An eighteenth aspect of the present invention is a cleaning tool in which a wiping body is gripped by a wiping body gripping portion of any one of the first to seventeenth torsional rotation type cleaning holders.

  A nineteenth aspect of the present invention is a cleaning tool, wherein the wiping body is any one of a pile mop, a sponge body, a brush body, a wiping cloth, and wiping paper.

According to the first aspect of the present invention, the joint portion is attached to the wiping body gripping portion and rotates the handle portion in the cleaning direction, and the protrusion extended from the lower stage joint portion. Since the upper joint is connected to the upper part and rotates the handle part in the longitudinal direction, the torsional force manually acting on the handle part directly acts on the upper joint part, and further on the lower stage side. Acting in conjunction with the joint part, applying a torsional rotational moment from the lower joint part to the wiping body gripping part, smoothly rotating the wiping body gripping part horizontally with respect to the floor surface, and changing the direction of the wiping body gripping part Can be easily performed.
Further, the upper joint portion is closely attached between the protrusion, a bearing portion having two bearing pieces that sandwich the protrusion in an outer fitting shape, and the bearing piece and the protrusion. The holding member is pivotally supported by the insertion of the sub shaft body. In other words, the upper joint portion is a longitudinal turning joint portion for turning the handle portion in the longitudinal direction. By the moment, a more suitable couple can be applied in the cleaning direction substantially perpendicular to the longitudinal direction, and the wiping body gripping portion can be rotated more reliably. That is, when the handle portion is twisted, the bearing piece presses the protrusion, and the pressing force becomes a couple and generates the torsional rotation moment. Therefore, the couple is substantially perpendicular to the longitudinal direction. Acting in the cleaning direction, the wiping body gripping portion is horizontally rotated with respect to the floor surface. The rotation of the handle portion in the longitudinal direction means that the surface of the bearing piece or the surface of the protrusion is provided in parallel or substantially parallel to the longitudinal direction, and the pressing force is substantially in the longitudinal direction. Acts in the vertical cleaning direction. That is, it is difficult for a movement that couples to occur at both ends in the longitudinal direction of the wiping body gripping portion, and the wiping body gripping portion can be stably rotated horizontally with respect to the floor surface. Therefore, the operability is better, and the user can freely change the direction of the cleaning tool and the like.
Further, when a torsion elastic body is fitted around the outer periphery of the auxiliary shaft body so as to fill at least the insertion hole of the protrusion, and the handle portion is twisted around the shaft, the elastic body is elastically deformed by the elastic deformation of the torsion elastic body. The bearing piece presses the protrusion while receiving a force to generate a torsional rotation moment, and the wiping body gripping portion can be easily horizontally rotated with respect to the floor surface by the elastic torsional rotation moment. Specifically, the bearing piece, the pressing member, and the protrusion are pivotally supported by inserting the auxiliary shaft body into the auxiliary shaft hole of the bearing piece, the through hole of the holding member, and the insertion hole of the protruding portion, Since the torsion elastic body is fitted on the outer periphery of the auxiliary shaft body and inserted into the insertion hole of the protrusion, the torsion elastic body is deformed by the protrusion when the torsional moment is applied, and Elasticity can be imparted to the twist, the durability of the upper joint portion can be improved, the life can be extended, and the operability of the cleaning holder by the handle can be improved. Since the torsional elastic body is fitted on the outer periphery of the auxiliary shaft body and inserted into the insertion hole of the protrusion, when the torsional rotational moment is applied, the torsional elastic body is deformed and some force is applied. The inner surface of the insertion hole of the protrusion that absorbs and is relatively hard does not come into pressure contact with the auxiliary shaft body, and durability can be improved. In other words, when the handle is twisted, the force acting on the bearing piece is subjected to elastic resistance by the elastic body for torsion, so that a part of the force is applied to the projection until the bearing piece sufficiently presses the protrusion. It is absorbed by the torsional elastic body through the auxiliary shaft body. Therefore, a rapid force does not act on the protrusion from the subshaft body, a suitable torsional rotational moment can be generated, and the operability of the cleaning holder by the handle can be improved.

According to the second aspect of the present invention, a facing gap is formed between the bearing piece and the pressing member so that the bearing piece can be twisted and rotated. It can be rotated by an angle allowed by the gap, and the rotation is prevented when the bearing piece collides with the pressing member. Further torsion becomes a pressing force against the pressing member, and this pressing force becomes a couple and generates a torsional rotating moment, and the wiping body gripping portion is rotated horizontally with respect to the floor surface. When the torsion elastic body of the first form is added, the bearing piece collides with the holding member and is prevented from rotating while resisting the elastic resistance due to the elastic deformation of the torsion elastic body. The torsional rotational moment is generated in the slow process, and the torsional rotational moment can be efficiently generated without damaging the member even by multiple operations.
In other words, when the handle portion is twisted around the shaft, the bearing piece presses the protrusion so as to fill the facing gap to generate a torsional rotational moment. When the facing gap is formed in a shape that relieves the contact pressure between the bearing piece and the pressing member, as a result, the collision between the two members is mitigated, so the handle portion is twisted, and the facing gap Then, the surface of the bearing piece can press the surface of the protrusion. In other words, since the bearing piece presses the protrusion so as to fill the facing gap, the force per area is relatively weak, the impact is reduced, and the wiping body gripping portion is stably rotated. be able to. Further, the facing gap can be set so that a more suitable couple acts to rotate the wiping body gripping portion by the torsional rotation moment. Therefore, it is possible to provide a cleaning holder that has good operability and can be freely changed in direction by the user.
The facing gap between the bearing piece and the pressing member may be any shape that relaxes the contact pressure between the bearing piece and the pressing member by a twisting operation of the handle, in other words, the bearing piece and the pressing member are Any shape that does not contact at a stretch may be used. For example, the facing distance between the surface of the bearing piece and the surface of the presser member is a radially outwardly inclined shape, a curved surface, or a multistage shape, or the bearing piece surface and / or the presser member surface. There is a shape in which a large number of particulate protrusions are dispersedly formed. In addition, even if the bearing piece surface and the pressing member surface face-to-face distance are parallel, there are various shapes such as a shape in which the gap between both surfaces is deformed while filling the flexible material between both surfaces and the flexible material is crushed when twisted. That is, any shape may be used as long as both surfaces sequentially contact each other without colliding at once.

    According to the third aspect of the present invention, the surface of the pressing member facing the bearing piece is formed to have an inclined surface, and the inclined surface is formed to increase the facing distance in the radially outward direction. A torsional rotation type cleaning holder in which the facing gap is configured as an inclined gap is provided. Therefore, the facing gap becomes a facing gap, and the bearing piece can press the protrusion so as to fill the facing gap via the pressing member, and is perpendicular or substantially perpendicular to the surface of the protrusion. The force acts more efficiently and can generate a torsional rotational moment. As described above, the surface of the protrusion to be pressed is parallel or substantially parallel to the longitudinal direction or the cleaning direction, and if a force perpendicular or substantially perpendicular to the surface of the protrusion is applied, the torsion is performed. The rotation moment can cause a more suitable couple to act on the wiping body gripping portion. Therefore, the wiping body gripping portion can be stably rotated by the torsional rotation moment. Furthermore, since the surface of the pressing member has an inclined surface, and the inclined surface is formed so as to increase the facing distance in accordance with the radially outward direction, the shape of the pressing member depends on the shape of the bearing piece, It is possible to design and mold appropriately, and to form a suitable facing gap. Moreover, even if the pressing member is damaged, it can be replaced relatively easily, and the facing gap can be maintained.

  According to 4 form of this invention, the surface of the said bearing piece which faces the said pressing member is formed so that it may have an inclined surface, and the said inclined surface is formed so that a facing space | interval may be increased according to radial direction outward, A torsional rotation type cleaning holder in which the facing gap is formed is provided. Accordingly, since the facing gap becomes the facing gap, an inclined surface with relatively good durability can be formed, and the facing gap can be maintained for a long period of time. In the upper joint portion, the bearing piece is a member to which a shaft is fitted, and is connected to the handle via the bearing piece. Therefore, when the bearing piece is formed from a material having relatively good durability and an inclined surface is formed on the surface of the bearing piece, it is possible to maintain a suitable facing gap for a long period of time. Further, according to the fourth embodiment, the pressing member may have a flat surface and is pressed evenly, so that it has a relatively long life and can be manufactured at a low cost.

  According to a fifth aspect of the present invention, the holding member is formed with a ball-like projection having a ball-like convex surface, and the bearing piece is formed with a concave portion having a concave surface, and the ball-like convex surface and the Provided is a torsional rotation type cleaning holder in which the pressing member and the bearing piece are arranged so that the concave surface slides, and the bearing piece can be torsionally rotated. The concave surface of the bearing piece is fitted with a spherical convex surface of the pressing member, and the sliding range is limited, but the concave surface and the spherical convex surface can slide slidably like a universal joint. In other words, the left and right presser member's spherical arcuate convex surfaces are inserted into the concave surfaces of the left and right bearing pieces, so that the torsional rotation of the left and right bearing pieces is stable and smooth when a twisting force is applied to the handle portion. The torsional rotation without damage can be realized even by multiple twisting operations. The torsional rotation is performed until the bearing piece and the presser member come into contact with each other, and the subsequent torsional force becomes a couple and generates a torsional rotation moment, and the wiping body gripping part is stably leveled with respect to the floor surface. Can be rotated.

  According to the sixth aspect of the present invention, the ball-like protrusion is formed at the center of the pressing member, and the concave portion is formed at the center of the bearing piece, between the bearing piece and the pressing member and in the periphery. A torsional rotation type cleaning holder in which a facing gap is formed in the region so that the bearing piece can be twisted and rotated. According to this configuration, the ball-like projections at the center of the left and right presser members are fitted into the recesses at the center of the left and right bearing pieces, and the ball-like projections are brought into sliding contact with the recesses by the twisting operation of the handle. However, when the bearing piece peripheral portion comes into contact with the presser member peripheral portion, the facing gap is filled and rotation is prevented. Therefore, the rotation range is limited to the width of the facing gap. The subsequent torsional force becomes a couple due to the contact, generating a torsional rotation moment, and the wiping body gripping portion can be stably rotated horizontally with respect to the floor surface.

  According to the seventh aspect of the present invention, since the torsion elastic body is also inserted into the through hole of the presser member, the durability of the upper stage side joint portion is further improved and the cleaning by the handle is performed. The operability of the holder can be further improved. The pressing member is tightly fitted between the bearing piece and the protrusion, and when a twisting force is applied to the handle portion, the bearing piece presses the protrusion through the pressing member. Therefore, when the elastic body for torsion is also inserted into the through hole of the presser member, both the presser member and the protrusion are rotated to press the elastic body for torsion, and the elastic body for torsion is efficiently It is elastically deformed to effectively give elasticity to the torsion process. That is, when the pressing member is attached to the protrusion, the force acting through the countershaft body is efficiently absorbed by the torsional elastic body, and a sudden force is prevented from acting, The bearing piece can press the protrusion through the pressing member, and a suitable torsional rotational moment can be generated.

  According to the eighth aspect of the present invention, the twisting elastic body is selected from an elastic body including a tubular elastic body, a ring-shaped elastic body, a piece-like elastic body, and a granular elastic body. The form of the torsional elastic body can be appropriately selected according to the above. When the torsional elastic body is a tubular elastic body, it is only necessary to fit the subshaft body to a tubular elastic body having a size suitable for the diameter and length of the subshaft body and the hole length of the through hole. The torsional elastic body can be attached to. When the torsion elastic body is a ring-shaped elastic body, the sub-shaft body may be fitted to a plurality of ring-shaped elastic bodies according to the diameter and length of the sub-shaft body and the hole length of the through hole. You can adjust the number of bodies. Even in the case of a piece-like elastic body or a granular elastic body, effective elasticity can be imparted to the twisting process by adjusting the number of grains to be charged.

  According to the ninth aspect of the present invention, the bottom surface of the wiping body gripping portion is formed in a longitudinal mountain shape along the longitudinal direction, and the longitudinal mountain shape is a longitudinal peak portion at the position of the joint portion. And having a longitudinal mountain skirt that decreases toward both ends in the longitudinal direction, the floor surface is in contact with the longitudinal peak only, and the frictional resistance from the floor surface is the longitudinal peak. The wiping body gripping part can easily be rotated horizontally (horizontal rotation) with respect to the floor surface around the longitudinal peak, by acting only on the part and reducing the frictional resistance. Accordingly, turning in the traveling direction is facilitated by the twisting operation of the handle, the cleaning direction can be changed more easily, and the operability can be further improved. The longitudinal chevron has a longitudinal summit at the position of the joint, and it only needs to be lowered along the direction of both ends, and the bottom surface of the wiping body gripping part can be various according to the type of wiping body. It can be formed in a longitudinal mountain shape. Further, when a pile-like wiping body is mounted on the wiping body gripping portion, the wiping body only comes into contact with the floor surface at the peak in the longitudinal direction, and since the frictional resistance is extremely small, turning by horizontal rotation is easy. In addition, the countless pile tips of the wiping body are in contact with the floor surface over the entire length in the longitudinal direction, and the floor surface can be cleaned over the entire length in the longitudinal direction.

  According to the tenth aspect of the present invention, since the longitudinal chevron is formed in a curved shape that forms a curved line over the entire length in the longitudinal direction, the wiping body gripping portion is more smoothly moved by the torsional rotational moment. It can be rotated. Since the contact point with the floor surface is a curved apex portion, and the tangent to the curved line corresponds to the surface to be cleaned, the area of the peak portion in the longitudinal direction where the bottom surface of the wiping body gripping portion is in contact with the surface to be cleaned such as the floor Since the frictional force acting is reduced and the wiping body gripping portion can be rotated and rotated more smoothly. Further, when the bottom surface is curved, even if the wiping body gripping portion is inclined in the longitudinal direction, the wiping body gripping portion is relatively stable, and the contact position is only slightly moved, so that suitable operability is maintained. be able to.

  According to the eleventh aspect of the present invention, the longitudinal mountain shape is formed in a triangular shape in which the longitudinal peak portion forms an apex, and the longitudinal peak portion forms an inclined straight line from the apex. It has a simple shape and can be easily processed. In particular, since the peak in the longitudinal direction is the apex, the contact area with the floor surface can be sharply reduced, and the frictional resistance during the rotation of the wiping body gripping part can be drastically reduced. Moreover, the manufacturing cost of the said wiping body holding | grip part can be reduced.

  According to a twelfth aspect of the present invention, the longitudinal mountain shape has a central flat left and right curved shape in which the longitudinal peak portion forms a flat line and the longitudinal peak portion forms a curved line from both ends of the flat line. Since it is formed, the stability of the wiping body gripping portion can be improved due to the flatness at the center. Furthermore, both ends of the flat line are formed in a curved shape, can contact with the surface to be cleaned relatively stably, and can maintain suitable operability even if the wiping body gripping portion is slightly inclined. it can. Further, as described above, the frictional resistance at the time of rolling is reduced because the flat line portion contacts the floor surface.

  According to a thirteenth aspect of the present invention, the longitudinal mountain shape is formed in a trapezoidal shape in which the peak in the longitudinal direction forms a flat line, and the bottom in the longitudinal direction forms an inclined straight line from both ends of the flat line. Therefore, the bottom surface of the wiping body gripping portion can be processed relatively easily and with relative ease. Furthermore, the area of the peak portion in the longitudinal direction is smaller than that of a flat bottom surface, and the wiping body gripping portion can be rotated by horizontal rotation relatively smoothly.

  According to a fourteenth aspect of the present invention, the longitudinal mountain shape is formed in a central flat left and right staircase shape in which the peak in the longitudinal direction forms a flat line, and the bottom in the longitudinal direction forms a staircase line from both ends of the flat line. Since it is formed, the longitudinal chevron can be formed relatively easily. For example, the bottom surface does not need to be integrally formed with a mold or the like, and plate-like members having different areas can be formed in layers in order of size. Further, it is sufficient that there are two or more staircase lines. If the peak in the longitudinal direction has a small area, friction can be reduced and the wiping body gripping part can be rotated more smoothly.

  According to the fifteenth aspect of the present invention, since the bottom surface of the wiping body gripping part is a torsional rotation type cleaning holder formed in a cleaning direction flat type along the cleaning direction, a small peak in the longitudinal direction is provided. Since the area is in contact with the floor surface, and the frictional resistance from the floor surface is small, the wiping body gripping part can be easily rotated horizontally with respect to the floor surface by twisting the handle, and the wiping body gripping part travel direction Can be easily turned. Even when the wiping body is attached to the wiping body gripping part, the wiping body only comes into strong contact with the floor surface only at the peak in the longitudinal direction, and the wiping body receives less frictional resistance from the floor surface, so that the wiping body is placed on the floor. It is possible to easily rotate the wiping body in the advancing direction by easily horizontally rotating with respect to the surface. In addition, when the wiping body is a pile-shaped wiping body, the tips of many piles are in contact with the floor surface over the entire length in the longitudinal direction, so that the floor surface can be cleaned over the entire length in the longitudinal direction and at the same time. There is an advantage that the direction can be easily turned.

  According to the sixteenth aspect of the present invention, the bottom surface of the wiping body gripping portion is formed in a cleaning direction mountain shape along the cleaning direction, and the cleaning direction mountain shape is a peak portion in the cleaning direction at the position of the handle portion. And having a cleaning direction crest that decreases toward both ends in the cleaning direction, the horizontal rotation of the wiping body gripping portion with respect to the floor surface, that is, the rotation in the cleaning direction is further facilitated. More specifically, since the wiping body gripping part is a longitudinal mountain shape and at the same time a cleaning direction mountain shape, the wiping body gripping part is formed on the floor surface only by a small area formed by the longitudinal direction mountain top part and the cleaning direction mountain top part. The frictional resistance from the floor surface that is received when the wiping body gripping portion is rotated can be extremely reduced, and the wiping body gripping portion can be turned on the floor surface, that is, in the cleaning direction. In addition, when the wiping body gripping part is advanced or retracted in the cleaning direction, when either or both of the front edge and the rear edge of the wiping body gripping part are lifted from the surface to be cleaned, the floor is removed from the floating gap. Dust on the surface can be taken near the center of the wiping body and used without replacement until the entire surface of the wiping body becomes dirty. Therefore, not only the cleaning efficiency of the wiping body is increased, but also the replacement period of the wiping body can be extended, so that the life of the wiping body can be extended. In general, the wiping body can be used more efficiently.

  According to the seventeenth aspect of the present invention, the cleaning direction chevron formed in the cleaning direction is any one of a triangular shape, a central flat left and right curved shape, a trapezoidal shape, a central flat left and right stepped shape, or a curved shape. Therefore, the shape of the bottom surface of the wiping body gripping portion can be selected according to the structure of the wiping body.

  According to the eighteenth aspect of the present invention, since the wiping body is held by the wiping body gripping portion of the torsional rotation type cleaning holder according to any one of the first to seventeenth aspects, the operability is improved. Therefore, it is possible to provide a cleaning tool that can be freely changed in direction by the user.

  According to the nineteenth aspect of the present invention, since the wiping body is any one of a pile mop, a sponge body, a brush body, a wiping cloth, and wiping paper, the wiping body can be selected according to the characteristics of the surface to be cleaned. . For example, when the wiping body is a pile mop, the pile mop is in contact with the surface to be cleaned without being influenced by the shape of the bottom surface of the wiping body gripping part, and thus dust such as a flat floor can be collected, and , Has excellent operability.

This longitudinal chevron has the highest longitudinal peak 58 at the lower position of the joint part 20, and has longitudinal peak hems 59, 59 that become lower toward the longitudinal ends 57, 57. ing. In the first embodiment, the longitudinal chevron is a curved line having a vertex at the longitudinal peak.

FIG. 2 is an exploded perspective view of the joint portion 20 of the first embodiment according to the present invention. In FIG. 1, it has been described that the longitudinal-direction rotating joint portion 30 is composed of a U-shaped bearing portion 31 in which a pair of bearing pieces 32 and 32 are connected in a U-shape. The bearing piece 32 includes an annular portion 32a having a countershaft hole 32b, an L-shaped portion 32c connected thereto, and a semi-cylindrical portion 32d comprising a vertical surface 32e and a semi-cylindrical surface 32f thereon. Consists of The annular portion 32 a has an annular inner surface 32 g that abuts against the presser plate 35 a of the presser member 35.
The pressing member 35 includes an annular pressing plate 35a having a pressing plate surface 35b that abuts on the annular inner surface 32g. The pressing plate 35a has a through hole 35c having a through hole diameter d ′. An annular protrusion 35d is formed on the surface opposite to the presser plate surface 35b so as to have an outer edge ring 35e and an inner edge ring 35f to be an annular plate 35g. The pressing plate surface 35b is formed as an umbrella-shaped inclined surface, but the annular plate 35g is formed as a flat annular plate, and the inclined surface which is the pressing plate surface 35b is formed as an inclined surface except for the annular plate 35g. Is done. Of course, the entire pressing plate surface 35d including the annular plate 35g may be formed as an inclined surface.

At both ends of the main shaft body 43, projecting shaft portions 43c and 43c are projected through steps 43b and 43b. A protrusion 44 projects from the main body body 43 a of the main body 43. An outer annular projection 44b and an inner annular projection 44c are formed on both surfaces of the projection 44 with an annular groove 44a therebetween, and an insertion hole 44d having an insertion hole diameter D ′ is drilled inside the inner annular projection 44c. Has been. The annular protrusion 35d of the pressing member 35 is inserted into the annular groove 44a, the annular plate 35g is in contact with the outer annular protrusion 44b, and the inner edge ring 35f is in contact with the inner annular protrusion 44c. .

  The torsion elastic body 34 is an annular body having an elastic body diameter d (outer diameter) formed of an elastic material such as rubber or flexible resin, and a hole is formed on the inner surface thereof. The torsion elastic body 34 is disposed on the outer periphery of the shaft body body 33a, and D ≦ d is established. Since the torsion elastic body 34 is inserted into the insertion hole 44d, d ≦ D ′ is established. Therefore, D ≦ d ≦ D ′ is established. Further, since the shaft body barrel portion 33a of the auxiliary shaft body 33 is inserted into the through hole 35c of the pressing member 35, d ′ ≧ D is established.

  FIG. 3 is a longitudinal sectional view of the joint portion 20 of the first embodiment. Each member shown in the exploded perspective view of FIG. 2 is assembled as shown in FIG. The annular inner surface 32g of the bearing piece 32 is formed in a vertical surface, and the pressing plate surface 35b of the pressing member 35 is formed in an inclined surface as going outward in the radial direction. Therefore, the facing gap between the bearing piece 32 and the pressing member 35 has a facing gap 36 in which the facing distance increases in the radially outward direction. When the outermost annular plate 35g of the pressing member 35 is a flat annular plate, the facing gap 36 extends to the middle region, but it may be. It is sufficient if the facing gap 36 that can be deformed is formed so that the presser plate surface 35b contacts the annular inner surface 32g when a twisting force is applied to the handle portion 10. Four facing gaps 36 are formed at upper and lower left and right positions, and are configured to be deformable regardless of which direction the deformation occurs.

Further, the protruding shaft portion 33c is inserted into the auxiliary shaft hole 32b, and the stepped portion 33b of the auxiliary shaft body 33 is in contact with the annular inner surface 32g, so that the auxiliary shaft body 33 is not pulled out from the auxiliary shaft hole 32b. Is done. The torsion elastic body 34 is located between the pressing members 35 and 35 and is sized so as not to protrude outward from the through hole 35c.
Furthermore, the left and right semi-cylindrical portions 32d and 32d are configured such that the vertical surfaces 32e and 32e are in close contact with each other to form a cylindrical body, and are inserted into the connecting tube end portion 11b of the connecting tube 11, so that the assembly is not disassembled. The A threaded portion 11a is formed on the upper portion of the connecting tube 11, and a plurality of flexible pieces that can be bent through a plurality of slits are formed at the connecting tube end of the threaded portion 11a, although not shown. . The ends of the handle 13 are inserted inside these flexible pieces, and the fastening tube 12 is fastened to the threaded portion 11 a to connect and fix the handle 13 to the connecting tube 11 integrally. The handle part 10 includes a connecting pipe 11, a fastening pipe 12, a handle 13 and a grip part 14.

  FIG. 4 is a front view of the joint portion 20 of the first embodiment. The substrate 41 is fixed on the gripping portion upper portion 52 of the wiping body gripping portion 50, and the bearing portion 42 of the cleaning direction rotating joint portion 40 is formed integrally with the substrate 41. As described above, the main shaft body 43 is pivotally supported on the bearing portion 42, and the handle portion 10 can be rotated in the cleaning direction. Four facing gaps 36 are formed between the pressing member 35 and the annular portion 32a of the bearing piece 32 as shown in the figure. The specific configuration of the longitudinal-turning joint 30 is the same as that shown in FIG.

FIGS. 5A and 5B are a front view and a cross-sectional view taken along line HH of the joint portion 20 of the first embodiment when the handle is twisted in the direction of arrow a. (5A) is a front view of the joint portion 20 during twisting in the direction of arrow a. When the handle 13 is twisted in the direction of arrow a, the connecting tube 11 is also twisted integrally in the direction of arrow a. As a result, the annular portion 32a of the bearing piece 32 is also twisted in the direction of the arrow a, and the facing clearance of the right facing clearance 36 among the facing clearances 36 formed between the annular portion 32a and the pressing member 35 becomes narrower. On the other hand, the facing gap of the left facing gap 36 becomes wider.
(5B) is a cross-sectional view taken along the line HH of (5A), showing the structural deformation of the facing gap 36. When the annular portion 32a of the bearing piece 32 is twisted in the direction of the arrow a, it is twisted until the holding plate surface 35b of the holding member 35 and the annular inner surface 32g of the bearing piece 32 collide with each other. It has a slight twist rotation angle, and the relative positional relationship between the annular portion 32a and the protrusion 44 is inclined as shown in the figure. That is, the facing gap 36 on the lower right side is narrowed, and conversely, the facing gap 36 on the lower left side is widened.

  Next, the above twisting process will be described in detail. The state before applying the twisting force to the handle portion 10 is shown in FIG. In this state, no force acts on the torsion elastic body 34, and the torsion elastic body 34 is not elastically deformed at all. When a torsional force is applied in the direction of arrow a from this state, the force acts on the torsional elastic body 34 from the state of FIG. 3 to the state of FIG. 5B, and the torsional elastic body 34 is elastically deformed. In this elastic deformation process, an elastic resistance due to an elastic force acts on the torsional rotation of the handle portion 10, and the torsional resistance force is urged by a manual operation related to torsion. Accordingly, a person applies a torsional force while resisting the torsional resistance, and the torsion operation by the handle does not act instantaneously, and the torsional force is applied slowly over a certain period of time. The torsional deformation is alleviated and the torsional rotation moment slowly acts on the wiping body gripping part. As a result, horizontal rotation of the wiping body gripping part with respect to the floor surface easily occurs, and the direction of movement of the wiping body gripping part can be reliably changed. Therefore, the situation where the wiping body gripping part, which has been often generated at the time of changing the direction, is lifted from the floor and falls down, can be reduced to none. Conventionally, the smaller the inclination angle θ with respect to the floor surface of the handle portion, the easier the above-described toppling occurs. However, according to the present invention, it is possible to prevent the overturning even if the inclination angle θ is small.

  Even when the elastic body 34 for torsion is not provided, a facing gap is formed between the annular inner surface 32g of the bearing piece 32 and the pressing plate surface 35b of the pressing member 35. In particular, when the facing gap is the facing gap 36, Even if a torsional force is applied, torsional deformation occurs so as to fill the facing gap 36, and the torsional force is suppressed by the inclined surface of the facing gap 36, so the ease of changing the direction increases. When the torsional elastic body 34 is arranged in addition to the facing gap 36, an elastic resistance force is further applied to the torsional force, and the direction change can be realized more easily.

FIGS. 6A and 6B are a front view and a cross-sectional view taken along line I-I of the joint portion 20 of the first embodiment when the handle is twisted in the direction of arrow c. The direction of arrow c is opposite to the direction of arrow a. (6A) is a front view of the joint portion 20 during twisting in the direction of arrow c. When the handle 13 is twisted in the direction of arrow c, the connecting tube 11 is also twisted integrally in the direction of arrow c. As a result, the annular portion 32a of the bearing piece 32 is also twisted in the direction of the arrow c, and the facing clearance of the facing clearance 36 on the left side of the facing clearance 36 formed between the annular portion 32a and the pressing member 35 becomes narrower. On the other hand, the facing gap of the right facing gap 36 becomes wider.
(6B) is a cross-sectional view taken along the line II of (6A), showing the structural deformation of the facing gap 36. When the annular portion 32a of the bearing piece 32 is twisted in the direction of the arrow c, the annular portion 32a of the bearing piece 32 is twisted until the holding plate surface 35b of the holding member 35 and the annular inner surface 32g of the bearing piece 32 collide with each other. It has a slight twist rotation angle, and the relative positional relationship between the annular portion 32a and the protrusion 44 is inclined as shown in the figure. That is, the lower left facing gap 36 is narrowed, and conversely, the lower right facing gap 36 is widened. As a result, the torsional rotation moment based on the torsional force acts effectively, and the horizontal rotation of the wiping body gripping part 50 with respect to the floor surface can be easily performed. The detailed process has been described with reference to FIG.

  FIG. 7 is a longitudinal sectional view of a second embodiment (d ′ ≧ d) of the joint portion according to the present invention. This embodiment is different from FIG. 3 only in that both ends of the torsion elastic body 34 are inserted into the through holes 35 c of the pressing member 35. This is established by increasing the tube length of the torsional elastic body 34 when the condition that the through-hole diameter d ′ is larger than the elastic body diameter d, ie, d ′ ≧ d, is satisfied. And the elastic resistance force by the elastic body 34 for twist demonstrated in FIG. 6 acts, and the direction change of the wiping body holding | gripping part 50 can be easily caused based on a twist rotational moment by smooth transmission of a torsional force. Since the other configuration is exactly the same as that of FIG. 3, detailed description thereof is omitted.

FIG. 8 is a longitudinal sectional view and a transverse sectional view at the time of twisting the handle in the third embodiment of the present invention. (8A) is a vertical cross-sectional view of this another embodiment, (8B) is a cross-sectional view of the joint when the handle is twisted in the direction of arrow a, and (8C) is a twisted handle in the direction of arrow c. It is a cross-sectional view of the joint part.
In this alternative embodiment, the pressing plate surface 35b of the pressing member 35 is formed as a vertical surface, and the annular inner surface 32g of the bearing piece 32 is formed so as to expand outward in the radial direction, thereby forming the facing gap 36. That is, the facing gap of the facing gap 36 is designed to increase as it goes radially outward. The other configuration is exactly the same as that in FIG. Due to this inclination, the same action as in FIGS. 5 and 6 occurs. That is, when the connecting pipe 11 is twisted in the direction of arrow a by twisting the handle, the annular inner surface 32g is rotated until it comes into contact with the presser plate surface 35b, and as a result (8B), the facing gap 36 on the lower right side is narrowed. The facing gap 36 on the lower left side widens. Conversely, when the connecting tube 11 is twisted in the direction of the arrow c, the annular inner surface 32g rotates until it comes into contact with the presser plate surface 35b. As a result, as shown in FIG. The facing gap 36 is narrowed. As described above, the direction change of the wiping body gripping part 50 can be easily performed by this action.

The projecting portion 44 is formed so as to project integrally with the main shaft body 43. In the main shaft body 43, projecting shaft portions 43c and 43c are projected from both ends of the main shaft body barrel portion 43a via steps 43b and 43b.
The pressing member 35 includes a pressing plate 35a formed in a peripheral annular shape and a spherical arc-shaped convex portion 35h in the center.

The left and right pressing members 35 are constituted by a spherical arc-shaped convex portion 35h having an annular plate 35g, an annular projection 35d, and a spherical arc-shaped convex surface 35k. The annular protrusion 35d is fitted into and integrated with the annular groove 44a of the protrusion 44.
A recess 32h is formed in the bearing piece 32, and at least the inner peripheral surface thereof is formed as a concave surface 32k. The ball-like convex portions 35h, 35h of the left and right pressing members 35, 35 are fitted into the concave portions 32h, 32h of the left and right bearing pieces 32, 32, and the ball-like convex surface 35k and the concave surface 32k are in contact with each other and slide. A contact portion 32j is formed. The spherical isolated convex surface 35k and the concave surface 32k are formed in a spherical isolated surface so as to be in sliding contact with each other. Accordingly, the spherical convex portion 35h is configured to be slidable in a universal joint style with the concave portion 32h.
A facing gap 36 is formed between the annular plate 35 g of the pressing member 35 and the bearing piece 32. Accordingly, the facing gap 36 is a so-called play area, and the bearing piece 32 and the pressing member 35 (or the protrusion 44) can rotate within the area of the facing gap 36 in a limited manner. The dimension of the spherical arc-shaped convex portion 35h is designed so as to allow limited rotation within the facing gap 36, and the spherical arc-shaped convex portion 35h is configured to be slidably rotatable with respect to the concave portion 32h. ing.

(12B) is a cross-sectional view taken along the line QQ of (12A), and shows the structural deformation of the facing gap 36. When the bearing piece 32 is twisted in the direction of the arrow a, the holding member 35 is twisted until it collides with the bearing piece 32, and the bearing piece 32 has a slight torsional rotation angle. Are inclined as shown in the figure. That is, the facing gap 36 at the lower right side and the upper left side is narrowed, and conversely, the facing gap 36 at the lower left side and the upper right side is widened.

Next, the above twisting process will be described in detail. The state before the twisting force is applied to the handle portion, that is, the connecting pipe 11, is shown in (11B). In this state, no force acts on the torsion elastic body 34, and the torsion elastic body 34 is not elastically deformed at all. When a torsional force is applied from this state in the direction of the arrow a, the ball-shaped convex surface 35k slides on the concave surface 32k in (12B), while the bearing piece 32 twists and rotates clockwise to fill the facing gap 36. It rotates until the piece 32 collides with the annular plate 35g of the pressing member 35. During this torsional rotation process, the projection 44 and the hole wall surface of the holding plate 35 press the torsion elastic body 34, and the torsion elastic body 34 is elastically deformed as shown in (12B). Therefore, by twisting the handle while receiving this elastic reaction force, a torsional rotational moment acts on the wiping body gripping part 50, and the wiping body gripping part 50 rotates horizontally clockwise with respect to the floor surface. With this horizontal rotation, the traveling direction of the wiping body gripping portion 50 can be changed. The change in the traveling direction can be performed at an arbitrary angle, and can be freely adjusted from 0 degrees to 180 degrees depending on how torsional force is applied. In other words, since the twisting operation is performed while receiving an elastic reaction force (elastic force), the horizontal rotation is performed stably and smoothly, and the torsional rotation without damage can be realized even by the multiple twisting operations. The torsional rotation is performed until the bearing piece and the presser member come into contact with each other, and the subsequent torsional force becomes a couple and generates a torsional rotation moment, and the wiping body gripping part is stably leveled with respect to the floor surface. Can be rotated.
Therefore, the situation where the wiping body gripping part, which has been often generated at the time of changing the direction, is lifted from the floor and falls down, can be reduced to none. Conventionally, the smaller the inclination angle θ with respect to the floor surface of the handle portion, the easier the above-described toppling occurs. However, according to the present invention, it is possible to prevent the overturning even if the inclination angle θ is small.

  FIG. 13 is a front view and a cross-sectional view taken along the line RR of the joint portion 20 of the fourth embodiment when the handle is twisted in the direction of the arrow c, and is a drawing corresponding to FIG. 6 as a whole. (13A) is a front view of the joint portion 20 when the handle is twisted in the direction of arrow c. When the handle 13 is twisted in the direction of arrow c, the connecting tube 11 is also twisted integrally in the direction of arrow c. As a result, the bearing piece 32 is also twisted in the direction of the arrow c, and the facing distance of the left facing gap 36 is narrowed. Conversely, the facing distance of the right facing gap 36 is widened. (13B) is a cross-sectional view taken along the line RR of (13A), and shows the structural deformation of the facing gap 36. When the bearing piece 32 is twisted in the direction of the arrow c, the holding member 35 is twisted until it collides with the bearing piece 32, and the bearing piece 32 has a slight torsional rotation angle. Are inclined as shown in the figure. That is, the facing gap 36 at the upper right side and the lower left side is narrowed, and conversely, the facing gap 36 at the lower right side and the upper left side is widened.

Next, the above twisting process will be described in detail. The state before the twisting force is applied to the handle portion, that is, the connecting pipe 11, is shown in (11B). In this state, no force acts on the torsion elastic body 34, and the torsion elastic body 34 is not elastically deformed at all. When a torsional force is applied in the direction of arrow c from this state, in (13B), the ball-shaped convex surface 35k slides on the concave surface 32k and the bearing piece 32 twists counterclockwise so as to fill the facing gap 36, and the bearing It rotates until the piece 32 collides with the annular plate 35g of the pressing member 35. During this torsional rotation process, the projection 44 and the hole wall surface of the holding plate 35 press the torsion elastic body 34, and the torsion elastic body 34 is elastically deformed as shown in (13B). Accordingly, by twisting the handle while receiving this elastic reaction force, a torsional rotational moment acts on the wiping body gripping part 50, and the wiping body gripping part 50 rotates horizontally counterclockwise with respect to the floor surface. With this horizontal rotation, the traveling direction of the wiping body gripping portion 50 can be changed. The change in the traveling direction can be performed at an arbitrary angle, and can be freely adjusted from 0 degrees to 180 degrees depending on how torsional force is applied. In other words, since the twisting operation is performed while receiving an elastic reaction force (elastic force), the horizontal rotation is performed stably and smoothly, and the torsional rotation without damage can be realized even by the multiple twisting operations. The torsional rotation is performed until the bearing piece and the presser member come into contact with each other, and the subsequent torsional force becomes a couple and generates a torsional rotation moment, and the wiping body gripping part is stably leveled with respect to the floor surface. Can be rotated.
Therefore, the situation where the wiping body gripping part floats from the floor and falls down can be reduced to none. Moreover, even if the inclination angle θ of the handle portion with respect to the floor surface is small, the wiping body gripping portion can be prevented from falling.

  FIG. 14 is a front view in the AA line direction of FIG. 1 showing the torsional rotation type cleaning holder of the first embodiment in which the longitudinal mountain-shaped contour is curved. As shown in the drawing, the cleaning direction projection contour line, that is, the longitudinal ridge is apex at the longitudinal peak 58, and the longitudinal ridges 59 and 59 gradually lower on the left and right form a curved line as a whole. . Therefore, it is the curved apex that is the peak in the longitudinal direction that comes into contact with the floor surface during cleaning. Since the contact area with the floor surface is extremely small, it is easy to horizontally rotate the wiping body gripping part 50 parallel to the floor surface. Details thereof will be described with reference to FIGS.

  15 is a cross-sectional view taken along line BB, line CC, and line DD in FIG. (15A) is a cross-sectional view taken along the line BB in FIG. 1 and shows that the lower bottom surface 56 of the wiping body gripping part 50 is formed on the flat surface 62 in the cleaning direction. (15B) is a cross-sectional view taken along the line CC of FIG. 1, and shows that the lower bottom surface 56 is formed on the flat surface 62 in the cleaning direction. Further, (15C) is a sectional view taken along the line D-D of FIG. 1, and shows that the lower bottom surface 56 is formed on the flat surface 62 in the cleaning direction. Accordingly, in the grip portion lower portion 54 of FIG. 1, the longitudinal chevron forms a curved line and is a flat surface in the cleaning direction. Therefore, the longitudinal peak portion 58 has a width in the cleaning direction while the apex of the cleaning direction projection contour line is one point. In any case, since the contact area with the floor surface is extremely small, the horizontal rotation operation with respect to the floor surface by the twisting operation of the handle is extremely easy.

  FIG. 16 is a schematic cross-sectional front view of a cleaning tool in which a pile-like wiping body is mounted on a torsional rotation type cleaning holder according to the present invention. The wiping body 70 is a pile-shaped wiping body in which a large number of piles 72 are formed on the lower surface of the base cloth 71. Longitudinal ends 57 and 57 of the wiping body gripping portion 50 are inserted into the left and right wiping body end portions 73 and 73 so that the wiping body 70 is not pulled out from the wiping body gripping portion 50. ing. In the present invention, the entire wiping body 70 attached to the wiping body grip 50 is referred to as a cleaning tool. When the cleaning tool is brought into contact with the floor surface during cleaning, the longitudinal crest portion 58 of the wiping body gripping portion 50 comes into contact with the floor surface via the wiping body 70, but longitudinal crest portions 59, 59 on the left and right sides thereof. Is floating from the floor. However, since the pile has a length, at least the pile tip of the pile below the longitudinal mountain hem 59, 59 is in contact with the floor surface and below the longitudinal peak. Of course, the pile also touches the floor. Therefore, when the cleaning tool is pushed and pulled through the handle in the cleaning direction, the floor surface is cleaned by the pile in the entire length in the longitudinal direction. Further, when the handle portion 10 is twisted in this state, the longitudinal mountain peak 58 presses the floor surface, but the longitudinal mountain foot portions 59 and 59 float from the floor surface. 59, there is almost no friction with the floor surface, and even if the pile 72 is in contact with the floor surface, the contact pressure is small. That is, the frictional force received from the floor surface is only the peak portion 58 in the longitudinal direction, and the cleaning tool can be easily rotated horizontally with respect to the floor surface by the torsional rotation of the handle portion 10, and the direction of the cleaning direction can be easily changed. .

FIG. 17 is a perspective view for explaining the operation of the handle portion when the wiping body gripping portion of the torsional rotation type cleaning holder according to the present invention is horizontally rotated with respect to the floor surface. In the figure, the FF line represents a floor surface, and the G line represents a floor parallel line parallel to the floor surface FF line. Assume that the handle portion 10 is inclined with respect to the floor parallel line G by an inclination angle θ. At this time, when the grip portion 14 of the handle portion 10 is twisted in the direction of the arrow a, a torsional rotational moment in the direction of the arrow b acts on the wiping body gripping portion 50 via the joint portion 20 indicated by the broken line. The wiping body gripping part 50 rotates horizontally with respect to the floor surface FF in the direction of arrow b. In the present invention, the longitudinal peak 58 of the wiping body gripping part 50 is only in contact with the floor surface, the frictional resistance force received from the floor surface during horizontal rotation is small, and horizontal rotation in the direction of arrow b is easily performed. .
2 to 13, when the joint portion 20 using the elastic torsion force of the present invention is used, even when the inclination angle θ is small, the handle portion 10 is twisted. The wiping body gripping part 50 can be easily horizontally rotated in the direction of the arrow b.

18 is a cross-sectional view of the floor surface of FIG. 17 and is a schematic diagram for explaining the operation of the handle portion. The longitudinal peak part 58 of the wiping body gripping part 50 is in contact with the floor surface F of the floor part 75, but the longitudinal peak part is not in contact with the floor surface F. When the grip portion 14 is twisted in the direction of arrow a with the handle portion 10 tilted by the tilt angle θ with respect to the floor parallel line G, the wiping body gripping portion 50 is moved to the arrow via the joint portion 20 indicated by the broken line. It rotates horizontally with respect to the floor F in the b direction. Of course, when the grip portion 14 is twisted in the direction opposite to the arrow a, it is natural that the wiping body gripping portion 50 rotates horizontally with respect to the floor surface F in the direction opposite to the arrow b. As described above, since the wiping body gripping portion 50 is only in line contact with the floor surface at the longitudinal peak 58, the frictional resistance during horizontal rotation is small, and horizontal rotation can easily occur. it can.
Furthermore, when the joint portion 20 using the elastic torsional force of the present invention is used, even when the inclination angle θ is small, the wiping body gripping portion 50 can be easily leveled in the direction of the arrow b only by twisting the handle portion 10. Can be rotated.

FIG. 19 is a perspective view of a torsional rotation type cleaning holder having a rectangular flat plate type wiping body gripping portion according to the present invention. FIG. 19 is different from FIG. 1 in that a rectangular flat plate-type wiping body gripping portion 50 is used. Accordingly, the gripper upper part 52 and the wiping body lower part 54 are both formed in a rectangular flat plate shape, and the lower bottom surface 56 is a rectangular flat plate surface. Since the cleaning direction turning joint 40 and the longitudinal turning joint 30 constituting the joint 20 have exactly the same structure as in FIG. 1, their detailed description will be omitted, and only the rectangular flat plate will be described.
The rectangular flat plate type is the same as that in FIG. 28 of Patent Document 1, but the structure of the joint portion 20 is characterized by this embodiment. In the rectangular flat plate-type wiping body gripping portion, as described above, the entire bottom bottom surface 56 contacts the floor surface. Therefore, when a twisting force is applied to the handle portion 10, the frictional resistance force from the floor surface increases. In the conventional example shown in FIG. 28, the wiping body gripping portion 50 often falls due to the torsional rotation moment. However, in this embodiment, the joint portion 20 is configured as shown in FIG. 3 and the facing gap 36 and the elastic body 34 for torsion are arranged, so that the torsional rotational moment acts on the wiping body gripping portion 50 slowly and slowly. As a result, the wiping body gripping part 50 can be rotated horizontally with respect to the floor surface, and the conventional example of FIG.

  FIG. 20 is a front view showing various longitudinal mountain-shaped contour lines in another embodiment of the torsional rotation type cleaning holder according to the present invention. Each of (20A) to (20D) corresponds to FIG. 9 in which the longitudinal chevron shape (cleaning direction projection contour line) is a curved line, and other reference numerals are the same as those in FIG. The details about are omitted.

(20A) is another embodiment of the cleaning holder 1 in which the longitudinal ridges (cleaning direction projection contour lines) of the wiping body gripping portion 50 are triangular. The longitudinal peak 58 is a triangular apex, and the left and right longitudinal peaks 59 and 59 are straight lines extending from the longitudinal peak 58 to the longitudinal ends 57. Since the longitudinal summit 58 is a single point, when the wiping body gripping portion 50 rotates horizontally with respect to the floor surface, the frictional resistance force from the floor surface is greatly reduced, the horizontal rotation becomes easy, and the direction change is easy. Has the advantage of being able to Moreover, when a pile-shaped wiping body is mounted as a wiping body, the pile tips of a large number of piles come into contact with the floor surface, and the pile tips hold the cleaning tool and provide stability as a cleaning tool.
(20B) is another embodiment of the cleaning holder 1 in which the longitudinal chevron (cleaning direction projection contour line) of the wiping body gripping portion 50 has a central flat left and right curved shape. The longitudinal peak portion 58 is a central flat portion having a predetermined length, and the left and right longitudinal peak portions 59 and 59 are curved lines extending from the left and right end portions of the central flat portion to the longitudinal end portions 57 and 57. Since the longitudinal summit 58 is a central flat portion having a predetermined length, the frictional resistance force from the floor surface is obtained when the wiping body gripping portion 50 rotates horizontally with respect to the floor surface by shortening the flat length. Can be set small, horizontal rotation is facilitated, and the direction can be easily changed. Moreover, since it is a center flat left-right curved shape, the height from the floor surface of the wiping body holding | grip part 50 does not change rapidly, and it has stability as the wiping body holding part 50. FIG. When a pile-shaped wiping body is attached as a wiping body, the pile tips of a large number of piles come into contact with the floor surface, and the pile tips hold the cleaning tool and provide stability as a cleaning tool.

(20C) is another example of the cleaning holder 1 in which the longitudinal chevron (cleaning direction projection contour line) of the wiping body gripping part 50 has a central flat left and right slope shape. The longitudinal peak portion 58 is a central flat portion having a predetermined length, and the left and right longitudinal peak portions 59 and 59 are straight lines extending from the left and right end portions of the central flat portion to the longitudinal end portions 57 and 57. Since the longitudinal summit 58 is a central flat portion having a predetermined length, the frictional resistance force from the floor surface is obtained when the wiping body gripping portion 50 rotates horizontally with respect to the floor surface by shortening the flat length. Can be set small, horizontal rotation is facilitated, and the direction can be easily changed. Moreover, since it is a center flat left-right slope shape, it has stability as the wiping body holding | grip part 50 by a center flat part. When a pile-shaped wiping body is attached as a wiping body, the pile tips of a large number of piles come into contact with the floor surface, and the pile tips hold the cleaning tool and provide stability as a cleaning tool.
(20D) is another embodiment of the cleaning holder 1 in which the longitudinal chevron shape (cleaning direction projection contour line) of the wiping body gripping part 50 has a central flat left and right step shape. The longitudinal peak 58 is a central flat portion having a predetermined length, and the left and right longitudinal peaks 59 and 59 are multi-step staircase lines extending from the left and right ends of the central flat portion to the longitudinal ends 57 and 57. . The number of stairs can be adjusted as appropriate according to the length of the entire length in the longitudinal direction. Since the longitudinal summit 58 is a central flat portion having a predetermined length, the frictional resistance force from the floor surface is obtained when the wiping body gripping portion 50 rotates horizontally with respect to the floor surface by shortening the flat length. Can be set small, horizontal rotation is facilitated, and the direction can be easily changed. Moreover, since it is a center flat left-right step shape, it has stability as the wiping body holding | gripping part 50 by a center flat part. When a pile-shaped wiping body is attached as a wiping body, the pile tips of a large number of piles come into contact with the floor surface, and the pile tips hold the cleaning tool and provide stability as a cleaning tool.

In the present invention, as described above, the shape of the lower bottom surface 56 of the wiping body gripping portion 50 is made to be a mountain shape in the longitudinal direction, so that the contact area with the floor surface is reduced. The part 50 has a feature of facilitating horizontal rotation. In order to further reduce this frictional resistance, it is proposed that the wiping body gripping portion 50 is formed in a cleaning direction mountain shape over the entire length in the cleaning direction. Another reason for the cleaning direction chevron is that when the handle is pushed and pulled, the edge of the cleaning direction floats from the floor and a gap is formed between the floor and the dust is collected in this gap during push and pull. In addition, dust accumulates on the entire lower surface of the wiping body, and there is an effect that a large amount of dust can be collected for a long time. This has an advantage that the replacement period of the wiping body is prolonged. Furthermore, by combining the longitudinal chevron and the cleaning chevron, the contact area between the summit and the floor is further reduced, facilitating horizontal rotation at the longitudinal summit and the cleaning apex, and wiping. There is an advantage that the direction change of the body gripping portion 50 is further facilitated.
There are five types of longitudinal chevron: curved, central flat left and right triangular, central flat left and right curved, central flat left and right slopes, and central flat left and right steps. Similarly, there are five types of chevron shapes in the cleaning direction: central flat left and right triangular shape, central flat left and right curved shape, central flat left and right slope shape, central flat left and right step shape, and curved shape. When these are combined, 5 × 5 = 25 types of forms can exist, and various forms can be taken according to the purpose of the cleaning tool.
Furthermore, a cleaning direction flat type can be adopted for the longitudinal chevron. In this case, the longitudinal chevron is curved, central flat left and right triangular, central flat left and right curved, central flat left and right Since there are five types of slopes and central flat left and right stepped shapes, there can be 5 × 1 = 5 types of forms.
Which of the 25 + 5 = 30 types is used can be changed according to the purpose of cleaning. In addition, there are various modifications such as making the width of the wiping body gripping portion 50 a rectangular shape or narrowing the width toward the end in the longitudinal direction, and various modifications can be made according to the purpose. is there. In the following, among various forms, 5 forms are shown in FIGS.

  21 is a cross-sectional view taken along line JJ, line KK, and line LL in FIG. 20 (20A). (21A) is a sectional view taken along line JJ, (21B) is a sectional view taken along line KK, and (21C) is a sectional view taken along line LL. In this embodiment, the longitudinal ridge shape is a triangle shape, the cleaning direction ridge shape 60 (cleaning direction lower outline) is also a triangle shape, and the cleaning direction peak shape is a triangular apex. Since the longitudinal chevron is triangular and the cleaning chevron is triangular, the point of contact with the floor is ideally one point, and even if there is some flatness at the apex, there is friction with the floor. Resistance is minimized. When a pile-shaped wiping body is attached as a wiping body, the pile tips of a large number of piles come into contact with the floor surface, and the pile tips hold the cleaning tool and provide stability as a cleaning tool.

  22 is a cross-sectional view taken along line JJ, line KK, and line LL in FIG. 20 (20B). (22A) is a sectional view taken along line JJ, (22B) is a sectional view taken along line KK, and (22C) is a sectional view taken along line LL. In this embodiment, the longitudinal chevron is a center flat left and right curved shape, and the cleaning direction chevron 60 (cleaning direction lower contour line) is also a central flat left and right curved shape, so that the peak is a fine rectangular flat portion. The case is shown. Since the peak portion is a rectangular flat portion, the frictional resistance with the floor surface is reduced. When a pile-shaped wiping body is attached as a wiping body, the pile tips of a large number of piles come into contact with the floor surface, and the pile tips hold the cleaning tool and provide stability as a cleaning tool.

  23 is a cross-sectional view taken along line JJ, line KK, and line LL in FIG. 20 (20C). (23A) is a sectional view taken along line JJ, (23B) is a sectional view taken along line KK, and (23C) is a sectional view taken along line LL. In this embodiment, the longitudinal mountain shape is a center flat left and right slope shape (trapezoid), and the cleaning direction mountain shape 60 (cleaning direction lower contour line) is also a center flat left and right slope shape (trapezoid). A case of a flat rectangular portion is shown. Since the peak portion is a rectangular flat portion, the frictional resistance with the floor surface is reduced. When a pile-shaped wiping body is attached as a wiping body, the pile tips of a large number of piles come into contact with the floor surface, and the pile tips hold the cleaning tool and provide stability as a cleaning tool.

  24 is a cross-sectional view taken along line JJ, line KK, and line LL in FIG. 20 (20D). (24A) is a sectional view taken along line JJ, (24B) is a sectional view taken along line KK, and (24C) is a sectional view taken along line LL. In this embodiment, the longitudinal chevron is a center flat left and right staircase shape (multistage), and the cleaning direction chevron 60 (cleaning direction lower contour line) is also a center flat left and right staircase shape (multistage). A case of a flat rectangular portion is shown. Since the peak portion is a rectangular flat portion, the frictional resistance with the floor surface is reduced. When a pile-shaped wiping body is attached as a wiping body, the pile tips of a large number of piles come into contact with the floor surface, and the pile tips hold the cleaning tool and provide stability as a cleaning tool.

  FIG. 25 is a cross-sectional view taken along line JJ, line KK, and line LL in yet another embodiment of FIG. (25A) is a cross-sectional view taken along line BB, (25B) is a cross-sectional view taken along line CC, and (25C) is a cross-sectional view taken along line DD. In this embodiment, since the longitudinal chevron is curved and the cleaning direction chevron 60 (cleaning direction lower contour line) is also curved, the case where the peak is a fine point is shown. However, since both the longitudinal chevron and the cleaning chevron are curved, the peak is the curved top. Therefore, it has stability as a wiping body gripping part. Since the curved top is in contact with the floor surface, the frictional resistance with the floor surface is reduced. When a pile-shaped wiping body is attached as a wiping body, the pile tips of a large number of piles come into contact with the floor surface, and the pile tips hold the cleaning tool and provide stability as a cleaning tool.

  FIG. 26 shows another embodiment of the present invention, and is a perspective view and a cross-sectional view taken along the line MM of a cleaning holder having a wiping body gripping portion having a curved width. (26A) is a wiping body having a rectangular curved shape in which the plan view of the wiping body gripping portion 50 is rectangular (same width in the cleaning direction) and the longitudinal chevron of the front view (FIG. 14) is curved. FIG. 6 is a perspective view of another example of the grip part 50. (26B) is a cross-sectional view taken along line MM of (26A). It is clear from (26B) that the cleaning direction lower contour line 60 is a flat surface. In another embodiment, the longitudinal peak 58 is a top line, and the contact area with the floor is minimal. Therefore, since the curved top line comes into contact with the floor surface, the frictional resistance with the floor surface is extremely reduced. Since it is a mountain shape in the longitudinal direction, the stability when brought into contact with the floor surface is excellent. Moreover, when a pile-shaped wiping body is mounted as a wiping body, the pile tips of a large number of piles come into contact with the floor surface, and the pile tips hold the cleaning tool and provide stability as a cleaning tool.

  27 is a cross-sectional view taken along line MM in FIG. 26 showing another embodiment of the present invention. In the cross-sectional view taken along the line MM, various types of cleaning direction ridges are illustrated. (27A) shows a wiping body gripping portion 50 having a triangular shape in the cleaning direction, (27B) having a central flat shape in the cleaning direction, and (27C) having a central flat shape in the cleaning direction. A left and right inclined (trapezoidal) wiping body gripping portion 50 is shown. Further, (27D) shows a wiping body gripping part 50 whose cleaning direction chevron has a central flat left and right step shape, and (27E) shows a wiping body gripping part 50 whose cleaning direction chevron is curved. . It is possible to select which cleaning direction mountain shape is adopted according to the purpose of cleaning.

The overall effect of the present invention will be summarized. First, a torsion elastic body 34 is externally fitted on the outer periphery of the auxiliary shaft body 33 and inserted into the insertion hole 44d of the protrusion 44. When the torsional moment is applied, the protrusion 44 causes the torsion Since the elastic body 34 is deformed to give elasticity to the torsion, the durability of the upper joint portion is improved, the life is extended, and the horizontal rotation performance of the cleaning holder by the handle is improved. Operability can be improved.
Secondly, when a face-to-face clearance is formed between the bearing piece 32 and the holding member 35 in the structure of the joint portion 20 so as to relieve the contact pressure between the bearing piece 32 and the holding member 35, the handle When the part is twisted around the shaft, the bearing piece presses the protrusion so as to fill the gap between the faces and generates a torsional rotational moment that is not instantaneous, and the wiping body gripping part is compared by the torsional rotational moment. Can be rotated horizontally with respect to the floor surface. In particular, when the facing gap is an inclined gap, the bearing piece 32 and the presser member 35 slowly come into contact with each other during torsion, and the action of the torsional rotation moment can be lengthened in time, and the acting force can be slowed down. .
Thirdly, as the structure of the joint part 20, the holding member is formed with a spherical isolated protrusion having a spherical convex surface, and the bearing piece is formed with a concave part having a concave surface, The presser member and the bearing piece are arranged so that the concave surface slides, and the bearing piece can be twisted and rotated. The concave surface of the bearing piece is fitted with a spherical convex surface of the pressing member, and the sliding range is limited, but the concave surface and the spherical convex surface can slide slidably like a universal joint. In other words, the left and right presser member's spherical arcuate convex surfaces are inserted into the concave surfaces of the left and right bearing pieces, so that the torsional rotation of the left and right bearing pieces is stable and smooth when a twisting force is applied to the handle portion. The torsional rotation without damage can be realized even by multiple twisting operations. The torsional rotation is performed until the bearing piece and the presser member come into contact with each other, and the subsequent torsional force becomes a couple and generates a torsional rotation moment, and the wiping body gripping part is stably leveled with respect to the floor surface. Can be rotated.
Fourth, by making the shape of the lower bottom surface 56 of the wiping body gripping portion 50 into a longitudinal mountain shape, the contact area with the floor surface is reduced, and as a result, the frictional resistance force from the floor surface is reduced when the direction is changed. The wiping body gripping portion 50 is easily reduced in horizontal rotation.
Fifth, when the shape of the lower bottom surface 56 of the wiping body gripping part 50 is a ridge shape in the cleaning direction, the contact area between the peak portion and the floor surface is further reduced by combining the ridge shape in the longitudinal direction and the ridge shape in the cleaning direction. Thus, the horizontal rotation at the peak in the longitudinal direction and the peak in the cleaning direction becomes easy, and there is an advantage that the direction change of the wiping body gripping part 50 is further facilitated.
Sixth, another advantage of the cleaning direction chevron is that when the handle is pushed and pulled, the cleaning direction chevron lifts the edge from the floor surface to form a gap with the floor surface. Dust is collected, dust accumulates on the entire lower surface of the wiping body, and there is an effect that a large amount of dust can be collected for a long time, which has an advantage of prolonging the replacement period of the wiping body.

  The present invention is not limited to the above-described embodiments and examples, and includes various modifications and design changes within the technical scope without departing from the technical idea of the present invention. Needless to say.

  Since the torsional rotation type wiping body gripping part and the cleaning tool according to the present invention have the first to sixth technical effects described above, the rotational type wiping body gripping is innovative in the manufacture and sale of sold-out products. And a cleaning tool can be provided. Moreover, in the rental industry where consumers use harshly, the rotating wiping body gripping part and the cleaning tool of the present invention are new, original and innovative. Can be activated.
