A cleaning material holding head.

  The cleaning material holding head is mainly composed of a base that is hard to be deformed, which is made of a synthetic resin, metal, or other material alone or in combination.

  Further, the cleaning material holding head can be configured such that an operating handle is connected to the cleaning material holding head or includes an operating handle.

  The wiping material has a sheet-like wiping portion. The whole wiping material may be sheet-like, and a part of the wiping material may be a sheet-like wiping portion. The wiping material does not necessarily need to be in the form of a sheet other than the wiping portion located on the bottom surface side of the cleaning material holding head. The sheet-shaped wiping material or the sheet-shaped portion of the wiping material is made of a non-woven fabric, a woven fabric, another fabric, or other sheet-shaped material.

  In order to hold the wiping material on the cleaning material holding head, for example, in the state where the bottom surface side of the cleaning material holding head is covered with the wiping portion of the rectangular wiping material, the vicinity of the opposite sides of the wiping material is respectively cleaned. It can be performed by folding back to the upper part of the holding head and detachably fixing it with a wiping material fixing part such as a pressing part or a clamping part. The holding of the wiping material by the cleaning material holding head is not limited to these. For example, the cleaning material holding head and the wiping material are provided with one part and the other part of the surface fastener, respectively, or one and the other of the snap are provided. Thus, the predetermined location of the wiping material can be detachably fixed to the cleaning material holding head.

  (2) The shape of the cleaning material holding head in plan view need not be specific. As the shape of the cleaning material holding head, for example, it can have a longitudinal direction and a short direction in plan view (particularly, both end edges or one edge part in the short direction are straight lines in the longitudinal direction). It is preferable that the The first direction, which is the main wiping direction of the cleaning material holding head, can be a direction with good cleaning efficiency, for example, depending on the shape of the cleaning material holding head in plan view. The first direction, which is the main wiping direction of the cleaning material holding head in the case of one having a direction and a short direction, is generally the short direction. The second direction is a direction orthogonal to the first direction.

  (3) There is a standing thin piece group on the bottom side of the cleaning material holding head. The standing flake group may be one or two or more. For example, it is possible to have the standing thin piece groups on both sides of the intermediate position in the first direction of the cleaning material holding head, and both standing thin piece groups are provided symmetrically with respect to the intermediate position in the first direction, for example. You can, but you are not limited to this.

  (4) A large number of standing thin pieces constituting the standing thin piece group can stand downward on the bottom surface side of the cleaning material holding head and can be elastically bent in the thickness direction. As a constituent material of the standing thin piece, for example, a material having rubber-like elasticity such as synthetic rubber can be used.

  Each standing thin piece is preferably substantially flat, but is not necessarily limited thereto. The wall thickness of each standing flake can be constant, for example, the wall thickness gradually decreases downward, and the wall thickness of both side edge and lower edge is respectively the end. It can be reduced as it goes to.

  The shape of each standing thin piece in the front view (the direction in which the projected area is the largest) is, for example, a rectangular or square shape, an isosceles trapezoidal shape in which the lower base is shorter than the upper base (or vice versa), etc. The bottom edge of each upright flake that can be made can be a horizontal straight line, but is not limited thereto.

  The standing flakes can be, for example, 3 to 50 mm (preferably 4 to 30 mm, more preferably 5 to 25 mm) in width (horizontal width in the front view of the standing flakes), and in thickness, for example, 0.3 to 3 mm. (Preferably 0.5 to 2 mm), and in height, for example, 3 to 50 mm (preferably 4 to 30 mm, more preferably 5 to 25 mm).

  (5) When the cleaning material holding head is placed on a flat surface, a large number of the standing thin pieces constituting the standing thin film group can be in contact with the lower edge of all the standing thin pieces on the flat surface. However, it is not necessarily limited to this.

  Many standing thin pieces constituting the standing thin piece group can be all the same.For example, a plurality of kinds of standing thin pieces having different heights, widths, thicknesses, and the like are regularly or irregularly arranged. Can be. When wiping an object while pressing the wiping part located on the bottom surface side of the cleaning material holding head while the standing thin piece constituting the standing thin piece group is bent in the thickness direction, the standing thin piece group has a height or width. If there are multiple types of standing flakes with different thicknesses, etc., the strength and ease of bending of the wiping portion against the object will vary depending on the height, width, thickness, etc. of the standing flakes, It can correspond to the presence / absence, size and type of dust on the object.

  (6) A large number of the standing flakes constituting the standing flake group has a component whose thickness direction is the first direction. Desirably, it is a standing flake whose thickness direction is the first direction. Standing flake by wiping the object while moving the cleaning material holding head holding the wiping material having the sheet-like wiping part so that the wiping part is located on the bottom side in the first direction with respect to the object. In wiping the object in a state in which the standing thin pieces constituting the group press the wiping portion against the object while bending in the thickness direction, it is preferable that all are in the first direction, but this is not necessarily limited thereto. It should be noted that, in addition to the standing flakes constituting the standing flake group, even if the standing thin flakes having no component in the first direction in the thickness direction are provided on the bottom surface side of the cleaning material holding head, it does not depart from the present invention. Absent.

  (7) A standing flake group consisting of a large number of standing flakes that stand downward and can be elastically bent in the thickness direction, for example, in a state where a large number of standing flakes stand downward from a flexible base. It is possible to obtain the base and a large number of upright flakes as a part of a wiping material support formed integrally with a material having rubber-like elasticity (for example, synthetic rubber).

  Each of the standing flakes in the standing flake group can be elastically bent in the thickness direction substantially independently of each other. Even in a wiping material support in which a large number of standing flakes stand up from a flexible base and the base and a large number of standing flakes are integrally formed, the thickness of each standing flake can be easily bent. By appropriately setting the difficulty of deformation of the flexible base, etc., when each standing thin piece is bent in the thickness direction, the position and posture of the adjacent standing thin piece through the flexible base are substantially reduced. It can be assumed that there is no influence. However, even if each of the standing thin pieces in the standing thin piece group can be elastically bent in the thickness direction in conjunction with the adjacent standing thin pieces to some extent, it does not depart from the scope of the present invention.

  (8) The cleaning material holding head can be configured, for example, by holding the base side of the wiping material support below the rigid base (base that can be regarded as rigid in relation to the wiping material support). .

  In this case, the flexible base in the wiping material support is held by the base in a part (for example, an outer peripheral part or a part of the outer peripheral part and the inner part), and a part not held by the base A space may be provided between the substrate and the substrate. As a part of the outer peripheral part and the inner part, in the case where the cleaning material holding head has a longitudinal direction and a lateral direction in a plan view, for example, a part along the outer peripheral part and the center line in the longitudinal direction can be cited. When the cleaning material holding head is rectangular in a plan view, for example, a portion along the diagonal line with the outer peripheral portion can be cited.

  In addition, the flexible base in the wiping material support is held by the base in part, and there is a space in which the flexible base can be elastically bent between the part not held by the base and the base. In the case of the cleaning material holding head, the unevenness of the object and the dust on the object when the wiping part is pressed against the object by the standing thin piece due to the elastic deflection upward of the flexible base. It can be adapted to existence, size, type, and the like.

  (9) In the standing flake group, several or more standing flakes are arranged at intervals in the first direction, and several or more in the second direction that is perpendicular to the first direction (for example, 5 to 5 6 or more) are arranged at intervals.

  The term “several or more” means, for example, a large number of 5 to 6 or more.

  The interval means, for example, an interval of 1/10 to 5 times, preferably 1/5 to 2 times the lateral width of the upright flakes.

  The standing flakes do not require that the center positions in the width direction of the standing flakes are aligned on a predetermined straight line in the first direction.

  The standing flakes can be arranged at intervals along a predetermined straight line in the second direction, but need not necessarily be arranged on the predetermined straight line in the second direction.

  (10) In the standing flake group, a part of at least one standing flake is located on an arbitrary first direction line, and at intervals in the second direction (for example, at regular intervals or at certain rules) Preferably at a distance from one end portion in the first direction to the other end portion, preferably within a range not reaching the other end portion. Two or more standing thin pieces are arranged at intervals in the first direction on both sides of the entrance portion in the second direction.

  In the standing flake group, a part of at least one standing flake is located on an arbitrary first direction line. There is no standing thin piece in the recessed portion, but at least a part of the standing thin piece is located on the other end portion side on an arbitrary first direction line of the recessed portion.

  The standing flake group may have one or a plurality of (preferably 3 to 4 or more, more preferably evenly) recessed portions extending from one end portion to the other end portion in the first direction, and further in the first direction. One or a plurality of recessed portions extending from the other end portion to the one end portion may be provided.

  The width in the second direction of all the recessed portions or a portion of the recessed portions in the standing flake group is gradually reduced from one end portion (entrance side) in the first direction toward the other end portion (preferably symmetrical in the second direction [ For example, it is preferably reduced to an isosceles trapezoidal shape or an isosceles triangular shape]. In addition, the 2nd direction width | variety of all the recessed parts in a standing flake group or one part recessed part is not restricted to this, For example, it changes toward the other end part from the one end part (entrance side) of a 1st direction. It can also be set to not, or it can be reduced on the back side without changing on the entrance side.

  The width in the second direction of the recessed portion can be, for example, 3 to 50 mm (preferably 4 to 30 mm, more preferably 5 to 20 mm).

  The depth in the first direction of the recessed portion can be, for example, 10 to 100 mm (preferably 10 to 60 mm, more preferably 15 to 40 mm).

  (11) On the bottom surface side of the cleaning material holding head, there are one or more pressing ridges made of an elastic material protruding downward, and the lower end position of the pressing ridges is an upright constituting a standing flake group. It is above the lower end position of the thin piece and can be more difficult to bend than the thickness direction of the standing thin piece constituting the standing thin piece group.

  Such pressing ridges are made of the same material as the standing thin piece, for example, and the thickness of the rising thin piece is several times to several tens of times or more than the thickness of the standing thin piece. Compared to the above, it is difficult to bend several times to several tens of times or more.

  The pressing ridge portion may be located inside the standing thin piece group and / or outside the standing thin piece group (preferably near the outside of the standing thin piece group) on the bottom surface side of the cleaning material holding head.

  The direction of the pressing protrusion is preferably a second direction that is perpendicular to the first direction, which is the main wiping direction, but is not limited thereto.

  As a suitable example of what has a pressing ridge part in the bottom face side of a cleaning material holding head, what has a protruding ridge part in the 2nd direction at the center part and both ends in a 1st direction, respectively is mentioned. it can. In this case, for example, the pressing protrusions at both ends may be the same height, and the pressing protrusions at the center may be higher than the pressing protrusions.

  Further, a cleaning material holding head is configured by holding a wiping material support integrally formed with a flexible base, a large number of standing thin pieces, and one or more pressing protrusions on the lower side of the rigid base. be able to.
