Use a variety of techniques.

In order to achieve the above problems, the invention described in each of the claims is constructed.

The cleaning body of the present invention is a long seat member for holding a cleaning body for cleaning the cleaning object, and includes a grip portion and two holding members. In this case, the cleaning body can also be configured to include an additional holder in addition to the two bodies. The grip portion is configured as a grip area held by the user. Each of the holding systems constitutes a holding member that extends in parallel with the holding portion for holding the cleaning body in a predetermined longitudinal direction. The term "parallel" as used herein may be a form in which two holding bodies are arranged side by side, and includes a form in which two holding bodies are arranged in parallel with each other and a distance between two holding bodies. A form that is reduced toward the front end side. Each of the two holding bodies is configured as a flat elongated member, and the flat elongated member includes a fixed end portion, a free end portion, and an extended portion. The fixed end portion is formed in the elongated member and constitutes an end portion on the side of the grip portion. The free end portion is formed in the elongated member, and constitutes an end portion on the opposite side of the fixed end portion in the longitudinal direction. The extending portion is provided between the fixed end portion and the free end portion, and is configured to be connected to the plurality of extending faces which are different from each other in the longitudinal direction. That is, in this extension portion, a plurality of extension faces having different vertical vectors are connected to each other and extend in the strip direction. In this aspect, the structure in which the normal vector of the extended surface of the elongated member continuously changes along the longitudinal direction during the extension of the flat elongated member from the fixed end toward the free end A structure in which the normal vector of the extended surface of the elongated member is intermittently or stepwise changed along the longitudinal direction. Further, the extended surface constituting the extending portion includes a plane, a curved surface, a step surface, and the like.

According to this configuration, in each of the holding bodies, a plurality of extending faces that are oriented in mutually different directions are formed along the longitudinal direction between the fixed end portion and the free end portion, and the holding body can be made flexible. direction. Thereby, the user can respond to various cleaning applications without replacing the grip portion, whereby the use form of the cleaning body can be diversified. Further, by further processing by the shape of each of the holding bodies, the holding body is increased in structure having a flexible direction, and can be used without being limited by the surface of the material, at least on the manufacturing of the holding body, and is not required to be particularly expensive. A resin such as a thermoplastic elastomer can be made of an inexpensive material which is high in hardness and has no flexibility or low flexibility.

In the cleaning body according to another aspect of the present invention, the extending portion is formed between the fixed end portion and the free end portion, and a predetermined twist shape is formed around the long axis of the elongated member and extends in the longitudinal direction to form a plurality The structure of the plane is better. According to such a configuration, it is possible to easily form a plurality of extension faces different from each other in the longitudinal direction by the torsional shape of the flat elongated member. At this time, since the direction of the extending surface of each of the holding bodies gradually changes with the torsion surface in the longitudinal direction, as a result, a plurality of extending faces that face each other in different directions are formed. Regarding the predetermined twist shape referred to herein, the twist shape may be a shape that is twisted only in a certain direction, or may be combined with each other in a shape twisted in a different complex direction. Further, the twisted shape of the extending portion of one of the holding bodies and the twisted shape of the other holding body may be the same or different forms.

In the cleaning body according to another aspect of the present invention, it is preferable that one of the flat elongated members has a right-rotating direction twisting portion as an extending portion that is twisted in the right-hand rotation direction around the long axis and extends in the longitudinal direction. Further, the other flat elongated member has a left rotation direction twisting portion as an extending portion which is twisted in the left rotation direction around the long axis and extends in the longitudinal direction. According to such a configuration, the direction in which the flexibility is made can be made different by one of the elongated members and the other elongated member, and the use form of the cleaning body can be more diverse.

In the cleaning body holder according to another aspect of the present invention, each of the two flat elongated members has an upper edge portion and a lower edge portion in a direction intersecting the parallel surface of the two elongated members, and an expansion portion and a reduction are formed. The structure of the department is better. The expansion portion constitutes an upper edge portion of one of the flat elongated members and the other The distance between the upper edge portions of one of the flat elongated members is a portion that gradually expands from the fixed end portion toward the free end portion. The narrowing portion constitutes a portion where the distance between the lower edge portion of the one flat elongated member and the lower edge portion of the other flat elongated member gradually decreases toward the free end portion from the fixed end portion. According to this configuration, when the load acts on the expansion portion, the two elongated members are displaced while being deflected in the direction in which they are separated from each other in accordance with the shape of the expanded portion. Therefore, by using the expansion portion, it is extremely effective to clean the surface of the cleaning object by wiping the cleaning object, for example, by cleaning the object to be cleaned. Further, when the load acts on the reduced portion, the two elongated members are displaced while being bent toward each other in accordance with the shape of the reduced portion. Therefore, by using the reduced portion, it is extremely effective to clean a situation such as a narrow place, a gap, or the like via the cleaning body.

In the cleaning body according to another aspect of the present invention, the flat elongated member has a substantially rectangular cross-sectional shape, and the upper edge portion is formed by the edge portion of one of the short sides corresponding to the cross-sectional shape. It is preferable that the lower edge portion is formed at the edge portion of the other short side of the cross-sectional shape. According to this configuration, since both the upper edge portion and the lower edge portion can be formed by the flat-shaped holding body itself (edge portion), the structure of the cleaning body can be simplified.

The cleaning tool according to the present invention includes: a cleaning body seat having the above configuration; and a cleaning body held by the cleaning body holder and used for cleaning the cleaning object. The cleaning body is divided into a plurality of divided cleaning portions that are strip-shaped and has an inserted region and a space portion.

Thereby, in the inserted state in which the respective holding bodies 142 are inserted into the inserted region on the side of the cleaning body 110, the cleaning body 110 can be prevented from being detached and reliably held by the seat body 140.

Other specific configurations of the holding bodies 142, 142 of the cleaning body 130 described above are further described with reference to FIGS. 2 to 7 in addition to FIG. Here, FIG. 2 is a view of the holding bodies 142, 142 in FIG. 1 viewed from above, and FIG. 3 is a view of the holding bodies 142, 142 in FIG. 1 viewed from below. 3 to 7 are cross-sectional views showing different regions of the holding bodies 142, 142 in Fig. 3, respectively.

In the present embodiment, as shown in FIG. 1 and FIG. 2, in particular, each of the holding bodies 142 is formed as a flat member having a flat plate shape or a flat shape whose thickness is set to be substantially constant. Each of the holding bodies 142 has a substantially rectangular cross-sectional shape. Further, each of the holding bodies 142 has a predetermined twist shape between the fixed end portion 142a and the free end portion 142b, and extends in the first direction D1 which is the longitudinal direction of the holding body. The fixed end portion 142a and the free end portion 142b referred to herein correspond to the "fixed end portion" and "self" of the present invention, respectively. By the end".

Specifically, the right holding body 142 has an extending portion that extends in the first direction D1 to the free end portion 142b while being twisted in the right direction from the fixed end portion 142a in the first direction D1. The torsion portion in the direction of rotation. The extension between the fixed end portion 142a and the free end portion 142b corresponds to the "extension portion" and the "right rotation direction torsion portion" of the present invention. On the other hand, the left holding body 142 has an extending portion that extends in the first direction D1 to the free end portion 142b while being twisted in the left direction from the fixed end portion 142a in the first direction D1. Turn the direction of the twist. The extension between the fixed end portion 142a and the free end portion 142b corresponds to the "extension portion" and the "left rotation direction torsion portion" of the present invention. Finally, in the range of the two holding bodies 142, 142 from the fixed end portion 142a to the free end portion 142b, a twist angle of about 150 (also referred to as "displacement angle") is formed. The twist angle can be appropriately selected in accordance with the twist shape of each of the holding bodies 142, and for example, a twist angle of less than 90°, a twist angle of more than 180°, or the like can be selected.

According to the extension portion in which the above-described torsional shape is formed in each portion of each of the holding bodies 142, a plurality of extension faces different from each other in the normal vector (vertical vector) are connected along the long axis A1 or A2 (along the strip direction). . Thereby, since the direction of the extending surface of each holding body gradually changes with respect to the torsion surface in the longitudinal direction, as a result, a plurality of extending faces which are oriented in mutually different directions are formed. As shown in Fig. 4, in the portion near the free end portion 142b in the portion of the C-C line in Fig. 2, each of the holding bodies 142 extends on the plane P1 along the second direction D2. Therefore, in this part, the left and right holding bodies 142, 142 forms a cross-sectional shape that is symmetrical with respect to any of the second direction D2 and the third direction D3. Thereby, the first extending faces 11 and 11 extending on the plane P1 particularly have flexibility in the third direction D3.

As shown in Fig. 5, in the portion of the D-D line cross section in Fig. 2, each of the holding bodies 142 extends on a plane P2 or P3 which intersects the plane P1 along the second direction D2. In this case, the plane P2 and the plane P3 cross each other and extend. Therefore, in this portion, the left and right holding bodies 142, 142 have a cross-sectional shape that is symmetrical with respect to the second direction D2, and forms a cross-sectional shape that is asymmetric with respect to the third direction D3. Thereby, the second extension surface 12 extending on the plane P2 and the third extension surface 13 extending on the plane P3 each have flexibility in a direction intersecting both the second direction D2 and the third direction D3.

As shown in FIG. 6, at the portion of the EE line cross section in FIG. 2, each of the holding bodies 142 extends on a plane P4 or a plane P5 orthogonal to the plane P1 along the second direction D2, further by The tabs 143 extending on the plane P1 interact to form a T-shaped cross-sectional shape. In this case, the plane P4 and the plane P5 extend parallel to each other. Therefore, in this portion, the left and right holding bodies 142, 142 and the protruding piece 143 connected thereto form a cross-sectional shape that is symmetrical with respect to both the second direction D2 and the third direction D3. Thereby, the fourth extending faces 14, 14 extending on the plane P1 have in particular the flexibility in the third direction D3, and the fifth extending faces 15, 15 extending over the plane P4 or the plane P5 have in particular the second direction. The flexibility of D2.

Further, the portion of the E-E line cross section is a portion where the amount of twist (the degree of twist) of the holding body 142 is large, and the protrusion 143 can be provided at the portion. The function of preventing excessive deformation caused by the load (as a function of the reinforcing portion). Therefore, the protruding piece 143 which originally functions as a function of preventing the fall of the cleaning body 110 can also function as a reinforcing portion for the holding body 142, and is extremely reasonable.

As shown in Fig. 7, in the portion of the cross section of the FF line in Fig. 2, that is, the portion near the fixed end portion 142a, each of the holding bodies 142 is on a plane P6 or P7 which intersects the plane P1 along the second direction D2. Extend. In this case, the plane P6 and the plane P7 cross each other and extend. Therefore, in this portion, the left and right holding bodies 142, 142 have a cross-sectional shape that is symmetrical with respect to the second direction D2, and forms a cross-sectional shape that is asymmetric with respect to the third direction D3. Thereby, the sixth extending surface 16 extending on the plane P6 and the seventh extending surface 17 extending on the plane P7 each have flexibility particularly in a direction intersecting both the second direction D2 and the third direction D3.

According to the above configuration of each of the holding bodies 142, since a plurality of extending faces facing the mutually different directions are formed along the longitudinal direction between the fixed end portion 142a and the free end portion 142b, the holding body 142 of the seat body 140 is formed. , 142 can obtain flexibility in any direction. In other words, the right holding body 142 is a plurality of extending surfaces that face each other in different directions, and at least the first extending surface 11, the second extending surface 12, the fourth extending surface 14, the fifth extending surface 15, and the sixth extending surface 16 are formed. . Therefore, with respect to the right holding body 142, the first extending surface 11, the second extending surface 12, the fourth extending surface 14, the fifth extending surface 15, and the sixth extending surface 16 are connected between the extending surfaces and The extended extension surface constitutes an extension portion in which the extension planes different from each other in the normal direction are connected along the longitudinal direction. Similarly, the left retaining body 142 is designed At least a plurality of extending faces, which are mutually different directions, are formed with at least the first extending face 11, the third extending face 13, the fourth extending face 14, the fifth extending face 15, and the seventh extending face 17. Therefore, with respect to the left holding body 142, the first extending surface 11, the third extending surface 13, the fourth extending surface 14, the fifth extending surface 15, and the seventh extending surface 17, and the respective extending surfaces are connected The extended extension surface constitutes an extension portion in which the extension planes different from each other in the normal direction are connected along the longitudinal direction. Thereby, since each of the holding bodies 142 has flexibility in at least five different directions intersecting the extending faces, the direction in which the holding body 142 has flexibility can be increased, for example, the connecting portion 152 is centered. The range of approximately 360 degrees acts as a movable range and can be flexed in any direction. The first to seventh extending faces 11 to 17 referred to herein constitute the "multiple extended faces having different normal vectors from each other" of the present invention.

According to the above configuration, the user does not need to change the handle portion 150, and can be used for various cleaning purposes, whereby the use form of the cleaning body 130 can be diversified. In particular, in the present embodiment, the direction in which the flexible body 142 and the other holding body 142 are different in flexibility can be used, and the use form of the cleaning body 130 can be more diverse. Further, according to the present embodiment, a plurality of extending faces (first to seventh extending faces 11 to 17) different from each other in the longitudinal direction of the normal vector can be easily formed by the twisted shape of the flat elongated member. .

Further, by adopting a structure in which the shape of each holding body 142 is carefully treated to increase the direction in which the holding body has flexibility, it is not limited by the material surface, and at least on the manufacturing holding bodies 142, 142, it is not necessary to use a special Resin, such as expensive thermoplastic elastomer, can be used with high hardness and without An inexpensive material that is flexible or has low flexibility. As such an inexpensive material, a PP (polyethylene) resin can be used. Further, if necessary, a PP resin may be used as a main material, and a flexible material such as PE (polyethylene), LLDPE (linear low-density polyethylene), or elastomer may be added to the PP resin in an arbitrary ratio. Material.

Further, as shown in FIGS. 2 and 3, the edge portion 142c of each of the holding bodies 142 is a portion corresponding to the short side of the substantially rectangular cross-sectional shape, and the end side region before the first direction D1 (for example, in FIG. 2) The portion of the CC line cross section constitutes the outer side surface 145 of the holder. Further, as shown in FIG. 2 and FIG. 3, the edge portion 142c of each of the holding bodies 142 constitutes the holding in the proximal end side region 146 in the first direction D1 (for example, a portion of the EE line cross section in FIG. 2). The body upper edge portion 147 and the lower edge portion 148. Specifically, the upper edge portion 147 is formed by a short edge portion 142c corresponding to one of the substantially rectangular cross-sectional shapes, and constitutes a parallel surface with the two holding bodies 142 and 142 (for example, in FIG. 4 The plane P1) intersects the upper part of the direction (also referred to as "upper"). Further, the lower edge portion 148 is formed by the other short edge portion 142c corresponding to the substantially rectangular cross-sectional shape, and constitutes a lower constituent surface in the direction intersecting the parallel surface (also referred to as "below" Or "bottom"). The upper edge portion 147 and the lower edge portion 148 referred to herein correspond to the "upper edge portion" and the "lower edge portion" of the present invention, respectively. According to this configuration, since both the upper edge portion 147 and the lower edge portion can be formed by the flat holding body 142 itself (edge portion 142c), the structure of the cleaning body holder 130 can be simplified.

In this case, as shown in FIG. 2, the holding bodies 142, 142 have a constitution. The distance (interval) d1 between the two upper edge portions 147 is gradually expanded from the fixed end portion 142a toward the free end portion 142b. The expansion portion referred to herein corresponds to the "expansion portion" of the present invention. According to such a configuration, when the load (load) acts on the expansion portions (two upper edge portions 147, 147) of the holders 142, 142, the two holders 142, 142 will follow the shape of the expansion portion. The direction separating from each other (the direction of the blank arrow in Fig. 2) is deflected and displaced. Therefore, it is extremely effective to use the two upper edge portions 147 and 147 of the holding bodies 142 and 142 to wipe the cleaning object by wiping the cleaning surface 100, for example, and to wipe the cleaning object.

Further, as shown in FIG. 3, the holding bodies 142, 142 have a narrowing portion in which the distance (interval) d2 between the two lower edge portions 147 is gradually reduced from the fixed end portion 142a toward the free end portion 142b. The reduced portion referred to here corresponds to the "reduced portion" of the present invention. According to such a configuration, when the load (load) acts on the reduced portion (two lower edge portions 148, 148) of the holding bodies 142, 142, the two holding bodies 142, 142 will face the shape of the reduced portion. The directions in which they approach each other (the direction of the blank arrow in Fig. 3) are deflected and displaced. Therefore, the use of the two lower edge portions 148, 148 of the holders 142, 142 is extremely effective in cleaning, for example, a narrow space, a gap, or the like via the cleaning body 100.

Further, the cross-sectional shape of each of the holding bodies 142 is not limited to the cross-sectional shape shown in FIGS. 4 to 7, and may be appropriately changed into a circular shape, an elliptical shape, a semicircular shape, a semi-elliptical shape, and a triangular shape as needed. , quadrangular, polygonal, V-shaped, Y-shaped, X-shaped, star, etc. In this case, it can respond The thickness of each holding body 142 is set to different sizes in each part of the holding body.
