  In Japanese Patent Laid-Open No. 9-238876, when a floor surface or the like is cleaned by providing an inclined surface at least at the front and rear ends of the bottom surface of the head, the head and the floor surface or the like are moved forward of the head in the traveling direction. A cleaning tool is disclosed in which a gap is formed between the heads so that not only fine dust but also large dust can be taken into the bottom surface of the head without being removed by the head and reliably wiped off. ing.

  However, in the case of the cleaning tool described in Japanese Patent Laid-Open No. 9-238876, a certain amount of dust is likely to be removed by the head, and even if it cannot be removed by the head, the bottom surface of the head gets over the dust, It was easy to produce the result which cannot be wiped off.

Japanese Patent Laid-Open No. 9-238876

  The present invention has been made in view of the above-mentioned problems existing in the prior art, and the object of the present invention is to leave a relatively large dust over the bottom portion and leave behind or flip forward. It is an object of the present invention to provide a wiping material holder and a cleaning tool that are prevented from detaching forward when the wiping material holder that has been taken in is moved rearward and can be effectively captured.

(1) The wiping material holder of the present invention that achieves the above object,
A wiping material holder for wiping the surface to be cleaned by holding the sheet-shaped wiping material in a state where the cleaning sheet-shaped wiping material covers at least the bottom surface portion,
The wiping material holder includes a projecting portion made of a flexible material that projects to the front of at least the front side edge of the bottom surface in the main wiping direction,
The lower end position of the overhanging part is located above the gap in the vertical direction of the bottom part,
Forming a recessed portion having a lower opening in a portion between a side edge portion on the front side of the overhang portion and a side edge portion on the front side of the bottom surface portion;
The sheet-like wiping material is held in a state of covering a lower opening of the concave portion.

  Moreover, the cleaning tool of this invention is equipped with the wiping material holder of this invention.

  When the sheet-like wiping material is held in a state of covering at least the bottom surface portion of the wiping material holder, the sheet-like wiping material is placed between the front side edge portion of the overhang portion and the front side edge portion of the bottom surface portion. It will be in the state which covers the downward opening of the formed recessed part.

  In this state, when the surface to be cleaned is wiped forward in the main wiping direction with the sheet-like wiping material on the bottom surface side of the wiping material holder, relatively fine dust is removed from the vertical position of the bottom surface portion. Also, the sheet-like wiping material on the side of the bottom surface portion of the wiping material holder can be wiped by passing between the lower end position of the overhanging portion positioned above with a gap and the surface to be cleaned.

  On the other hand, the relatively large dust passes between the lower end position of the overhanging portion and the surface to be cleaned as the wiping material holder moves forward, or the overhanging portion made of a flexible material is caused by the dust. After passing through between the lower end position of the overhanging portion and the surface to be cleaned while deforming upward after the presence of the recess in the lower opening, the side edge on the front side of the overhanging portion and the front side of the bottom surface portion At the position of the concave portion of the lower opening formed in the portion between the two, the sheet-like wiping material can be captured by the portion covering the lower opening of the concave portion. It is effectively prevented from leaving such dust in the back, leaving behind, flipping forward, or moving the wiping material holder back in place, and removing it forward. Will increase.

  Moreover, the overhang | projection part made from a flexible material can exhibit the buffer effect of a wiping material holder, furniture, a wall surface, etc.

  (2) The concave portion may have a groove shape along the entire length of the side edge portion on the front side of the bottom surface portion.

  In this case, since the concave portion forms a groove shape along the entire length of the side edge portion on the front side of the bottom surface portion, relatively large dust can be effectively captured over the entire length of the side edge portion on the front side of the bottom surface portion.

  (2-1) The concave portion may have reinforcing rib-shaped portions made of a flexible material at intervals along the front side edge portion of the bottom surface portion.

  In this case, the groove-shaped concave portion is formed of a reinforcing rib-shaped portion made of a flexible material (for example, a wall-shaped rib-shaped portion orthogonal to the groove-shaped concave portion) on the front side of the bottom surface portion. Since it has intervals along the side edges (for example, intervals of 1 to 5 times, preferably 2 to 3 times the width of the recesses), the recesses in the lower opening are not hindered from capturing relatively large dust. The shape can be maintained.

  (3) The bottom surface of the wiping material holder may have a shape that gradually rises from the center side toward the front side edge.

  In this case, the bottom surface of the wiping material holder has a shape that gradually rises from the center side toward the front side edge, so that dust can reach the inner depth of the sheet-shaped wiping material that covers the bottom surface, Wiping and cleaning can be performed in a state where the wiping material wipes off dust in a wide range in the wiping direction.

  (3-1) The wiping material holder shall be located above the surface to be cleaned even if the front edge of the bottom surface is inclined downward so that the front end is horizontal. Can do.

  In this case, even if the front end portion of the bottom surface portion of the wiping material holder is inclined downward so as to be in a horizontal state, the overhanging portion is located above the surface to be cleaned, and the overhanging portion and the surface to be cleaned are Since there is a gap between them, it can be prevented that relatively fine dust is blocked at the overhanging part and cannot be taken into the bottom part, or that relatively large dust can be bounced at the overhanging part and cannot be captured. .

(4) The wiping material holder has a protruding portion made of a flexible material that protrudes to the front of the front side edge portion and the rear side edge portion of the bottom surface portion at least in the main wiping direction. Prepared,
The lower end position of the overhanging part is located above the gap in the vertical direction of the bottom part,
A portion between a front side edge portion of the overhang portion and a front side edge portion of the bottom surface portion, and between a rear side edge portion of the overhang portion and a rear side edge portion of the bottom surface portion. Each part is formed with a recess in the lower opening,
The said sheet-like wiping material shall be hold | maintained in the state which covers the downward opening of any recessed part of the front side and rear side of a bottom face part.

  In this case, the cleaning effect can be sufficiently exerted even when the held sheet-like wiping material is wiped in the forward or backward direction in the main wiping direction.

  According to the wiping material holder and the cleaning tool of the present invention, relatively fine dust is disposed between the lower end position of the overhanging portion located above the bottom surface portion with a gap from the vertical position of the bottom surface portion and the surface to be cleaned. It can pass and be wiped off by the sheet-like wiping material on the side of the bottom surface of the wiping material holder. On the other hand, the relatively large dust can be prevented from leaving forward when the bottom part gets over the back and left behind, flips forward, or moves the wiping material holder of the captured thing backward. It can capture effectively and the cleaning effect increases.

It is a bottom side perspective view of the lower member of a wiping material holder. It is a front view of the lower member of a wiping material holder. It is a side view of a cleaning tool. It is a side view of a cleaning tool. It is a partial expanded sectional view of a cleaning tool.

  (1) An embodiment of the present invention will be described with reference to the drawings.

  The drawings all relate to a cleaning tool comprising a wiping material holder A and a handle B as an example of an embodiment of the present invention.

  The wiping material holder A is formed by combining a rigid upper member D made of a synthetic resin with an upper side of a flexible lower member C made of an elastomer. The wiping material holder A has a rectangular shape in plan view, and the main wiping direction is the short direction in plan view.

  The handle B is connected to the upper center portion of the upper member D of the wiping material holder A so as to be freely laid down in any direction. As an example of means for making the handle B freely lie down in any direction as described above, as shown in FIGS. 3 and 4, it can be rotated around both horizontal axes orthogonal to the upper member D, respectively. A means for connecting the base of the handle B so that it can move can be mentioned.

  As the sheet-like wiping material S for cleaning, a square or rectangular non-woven fabric is generally used, but is not limited thereto. A material suitable for the form of the wiping material holder A can be used as appropriate, and the material is not necessarily limited to the nonwoven fabric. The sheet-like wiping material S may be what is wiped using a cleaning liquid in addition to so-called dry wiping.

  Holding portions (not shown) for holding a part of the sheet-like wiping material S on both end sides of both longitudinal side edges (long edges) on the upper side of the upper member D of the wiping material holder A, respectively. Z). This holding part is formed by two or more horizontal tongue pieces made of elastomer having pointed parts facing each other. However, the holding portion is not limited to such an embodiment, and for example, a holding portion that is mechanically clamped or an intertwining nonwoven fabric or the like such as a hook-and-loop fastener may be employed.

  The flexible lower member C made of an elastomer has a bottom plate portion E that is rectangular in plan view, which is a reduced size of the outer peripheral shape in plan view of the wiping material holder A, and extends over the entire periphery on the outer peripheral side of the bottom plate portion E. The overhanging portion F is provided.

  The bottom surface portion E1 of the bottom plate portion E is curved and inclined gradually upward in the lateral direction from the central portion toward the longitudinal side edges on both sides. Accordingly, when the wiping material holder A is placed horizontally and placed on the horizontal surface (cleaning target surface) at the bottom surface portion E1, it is gradually separated from the horizontal surface (cleaning target surface) toward the predetermined edge from the center side. Will be. The maximum inclination angle of the bottom surface portion E1 can be set to, for example, 3 to 15 degrees, preferably about 4 to 8 degrees. On the bottom surface portion E1, a plurality of corrugated hook-shaped portions E2 for 2.5 wavelengths are formed in parallel in the short-side direction at the same phase with a substantially half-amplitude interval in the long-side direction.

  The overhanging portion F includes a descending inclined plate portion F1 that inclines downward from the top of the bottom plate portion E, a vertical edge portion F2 that is suspended from the outer end portion of the descending inclined plate portion F1, and a side surface of the bottom plate portion E. It consists of reinforcing fin portions F3 that are orthogonal to the outer peripheral edge portion of the bottom plate portion E and extend across the lower surface of the inclined plate portion F1 and the inner surface of the vertical edge portion F2, and a large number of reinforcing fin portions F3 are provided at predetermined intervals in the circumferential direction. . The lower surface of the descending inclined plate portion F1 of the overhanging portion F, the inner side surface of the vertical edge portion F2, and the side surface of the bottom plate portion E form a groove-shaped recess G having a downward opening over the entire outer periphery of the bottom plate portion E. ing. A large number of reinforcing fin portions F3 are provided at intervals of 2 to 3 times the width of the groove-shaped recess G perpendicular to the groove-shaped recess G.

  Even if the front end portion of the bottom surface portion E1 of the wiping material holder A is inclined downward so that the front end portion is in a horizontal state, the front projecting portion F is positioned above the surface to be cleaned. Even if the rear end portion of the bottom surface portion E1 of the wiping material holder A is inclined downward so that the rear end portion is in a horizontal state, the rear projecting portion F is positioned above the surface to be cleaned.

  (2) The sheet-like wiping material S can be held by the wiping material holder A, for example, as follows. First, the sheet-like wiping material S whose one side is longer than the length in the longitudinal direction of the wiping material holder A is spread on the floor surface, and both of the wiping material holders A are opposed to the opposite sides of the sheet-like wiping material S. While the longitudinal side edges are parallel, the central position between the longitudinal side edges of the wiping material holder A substantially coincides with the central position between the opposite sides of the sheet-like wiping material S. The wiping material holder A is placed as described above. Of the sheet-like wiping material S, the outer portions of both side edges in the longitudinal direction of the wiping material holder A are folded back to the upper side of the wiping material holder A so as to wrap the wiping material holder A so as to be as loose as possible. The corresponding portions on each side of the sheet-shaped wiping material S are pushed into and held on both holding portions on each side. Thus, the sheet-like wiping material S can be held by the wiping material holder A in a state where the bottom surface of the wiping material holder A is covered with the sheet-like wiping material S.

  As shown in FIGS. 3 to 5, on the front side in the short direction of the wiping material holder A, the sheet-like wiping material S is composed of the front side edge portion of the bottom surface portion E1 and the front side of the overhanging portion F. Over the edge, it is stretched over the space between them and covers the lower opening of the groove-shaped recess G, and on the rear side in the short-side direction, the sheet-like wiping material S is a side edge on the rear side of the bottom surface portion E1. And over the side edge on the rear side of the overhanging portion F, it is stretched over the space between them and covers the lower opening of the groove-like recess G.

  In this state, the surface to be cleaned P was wiped forward in the short direction of the wiping material holder A, which is the main wiping direction, by the sheet-like wiping material S on the side of the bottom surface portion E1 of the wiping material holder A. In this case, relatively fine dust passes between the lower end position of the overhanging portion F and the surface to be cleaned P, which is spaced above the vertical position of the bottom surface portion E1, and the surface of the wiping material holder A. It can be wiped off by the sheet-like wiping material S on the side of the bottom surface portion E1.

  The bottom surface portion E1 of the wiping material holder A has a shape that gradually rises from the central portion side toward the front side edge portion, so that dust can reach the inner depth of the sheet-like wiping material S held by the bottom surface portion E1. The dust can be wiped off in a wide range in the wiping direction. Even when the bottom surface portion E1 is inclined downward, since there is a gap between the overhang portion F and the surface P to be cleaned, relatively fine dust is blocked in the overhang portion F and cannot be taken into the bottom surface portion E1. It is prevented.

  Further, when the surface to be cleaned P is wiped by the sheet-like wiping material S, dust on the surface to be cleaned P is between the adjacent corrugated ridges E2 with respect to the sheet-like wiping material S (for example, an arrow V in FIG. 1). ) In the short direction, the dust along the corrugated corrugated portion E2 in the position where the angle formed by the corrugated corrugated portion E2 and the wiping direction becomes large (for example, the X portion and the Y portion in FIG. 1). Is easily captured by the sheet-like wiping material S.

  On the other hand, the relatively large dust T passes between the lower end position of the overhanging portion F and the surface P to be cleaned as the wiping material holder A moves forward as indicated by an arrow in FIG. Alternatively, the overhanging portion F made of a flexible material is deformed upward after the presence of the groove-shaped recess G having a lower opening by the dust T, and between the lower end position of the overhanging portion F and the surface P to be cleaned. When it passes, as shown in FIG. 5 (b), at the position of the groove-shaped recess G of the lower opening formed in the portion between the vertical edge F2 of the overhanging portion F and the side surface of the bottom plate portion E. Of the sheet-like wiping material S, the sheet-like wiping material S can be captured by a portion covering the lower opening of the recess G. For this reason, it is possible to effectively prevent such a dust T from being left behind when the bottom surface portion E1 gets over, flipped forward, or moved away when the wiping material holder A is moved backward. The cleaning effect is increased. Moreover, since the recessed part G makes the groove shape along the full length of the front side edge part of the bottom face part E1, it can supplement a comparatively big dust T over the full length of the front side edge part of the bottom face part E1 effectively. .

  Further, the groove-like recesses G have reinforcing rib-like portions made of a flexible material at intervals of 2 to 3 times the width of the recesses G along the front side edge of the bottom surface E1. Therefore, it is possible to effectively supplement the relatively large dust T while maintaining the shape of the concave portion G of the lower opening.

  Further, even when the bottom surface portion E1 is tilted downward, since there is a gap between the overhanging portion F and the surface to be cleaned P, a relatively large dust T can be repelled in the overhanging portion F and cannot be captured. It is prevented.

  The same applies to the case of wiping backward in the main wiping direction.

  Moreover, the overhang | projection part F made from a flexible material can exhibit the buffer effect of the wiping material holder A, furniture, a wall surface, etc. FIG.

  (3) The bottom surface portion of the wiping material holder in the present invention may be inclined at a constant angle or a plurality of angles instead of a curved inclination, or may be a flat surface without an inclination. Further, the bottom surface portion is a flat surface having no corrugated portion or the like, in addition to those having corrugated corrugated portions, triangular corrugated corrugated portions or the like, or those having other shapes of corrugated portions. You can also.

  Moreover, when using the wiping material holder of this invention, for example as a handy mop, a pattern can be fixedly provided substantially horizontally with respect to the wiping material holder. It is also possible to use it without providing a handle.

  The main wiping direction of the wiping material holder is the main direction when wiping the surface to be cleaned with the wiping material holding tool of the present invention, and the wiping material holding tool has a short view in which the plan view shape is perpendicular to the longitudinal direction. In the case of a shape whose direction is determined (for example, a rectangle, a square, an ellipse, etc.), it is usually a longitudinal direction or a lateral direction. Of these, the short direction in which the range to be wiped is wide is often the main direction. In the case of a shape such as a circle in which the longitudinal direction and the short direction are not determined, any direction can be used as the main wiping direction.

  The projecting portion is made of an elastomer or other flexible material, and can project to, for example, 5 to 20 mm outward from the outer periphery of the bottom surface portion. The overhanging direction of the overhanging portion is not only in front of the side edge portion on the front side of the bottom surface portion in the main wiping direction, but also behind the side edge portion on the back side of the bottom surface portion in the main wiping direction, Can include side outwards.

  When the wiping material holder is horizontally placed on the horizontal surface at the bottom surface portion, the lower end position of the overhanging portion shall be positioned above the horizontal surface with a gap of, for example, 1-10 mm. Can do.

  Further, the concave portion of the lower opening formed in the portion between the front side edge portion of the overhang portion and the front side edge portion of the bottom surface portion may be formed in the overhang portion itself, It may be formed by the protruding portion and the side edge portion of the bottom surface portion.
