The figure shows one embodiment of a wiper with a compression mechanism according to the present invention. As can be seen from FIGS. 1 and 2, the wiper includes an elongated rod-shaped cleaning member 1 made of a porous material that is superior in water absorption and water retention, such as a synthetic resin foam, and the cleaning member 1. A head plate 2 that is elongated to the left and right for detachable attachment and that can be bent in two at the center, a head support frame 3 that supports the head plate 2, and a head support frame 3 that is attached to the center of the upper end of the head support frame 3. A wiper head H is formed by the head plate 2 and the cleaning member 1, which has a handle bar 4 whose length can be freely adjusted and an operation mechanism 5 for bending the head plate 2. Then, the handle 4 is held in the hand, and the cleaning member 1 containing water is pressed against an object to be cleaned such as a floor surface to perform water wiping cleaning.
Examples of the synthetic resin foam excellent in water absorption and water retention include a sponge made of polyvinyl alcohol (PVA).

  The cleaning member 1 has a cross-sectional shape in which the bottom portion of the square bar and both side portions are connected in a rounded manner, and the longitudinal direction of the cleaning member 1 extends from the bottom surface to the lower ends of both side surfaces. A plurality of small grooves 1a extending in the entire length are provided in parallel. However, this small groove 1a is not necessarily required. Further, as can be seen from FIGS. 3 and 5, the flat upper surface of the cleaning member 1 corresponds to the pair of head substrates 16 and 16 in the head plate 2 except for the central portion 1 b that becomes a bent portion when compressed. The connecting plates 10 and 10 are respectively attached to the positions where they are to be performed.

  The connecting plate 10 is made of a hard or semi-rigid synthetic resin, and is fixed to the cleaning member 1 with an adhesive. A plurality of locking bullets 11A and 11B are provided on the upper surface of the connecting plate 10. Are provided integrally. The locking bullets 11A and 11B are composed of a leg portion 11a rising upward from the connecting plate 10 and a locking portion 11b extending laterally from the upper end of the leg portion 11a. Two pairs of locking bullets 11A and 11B are made up of a pair of a first locking bullet 11A located at one end in the width direction (short direction) and a second locking bullet 11B located at the other end. The connecting plate 10 is disposed at a position near one end and a position near the other end in the longitudinal direction. The difference between the first locking bullet 11A and the second locking bullet 11B is that the directions of the locking portions 11b are opposite to each other. In the following description, when it is not necessary to distinguish between the first locking bullet piece 11A and the second locking bullet piece 11B, only “locking bullet piece 11” is displayed. .

  The head plate 2 includes a support base 15 located in the center, a pair of left and right head substrates 16 and 16 rotatably connected to the support base 15, and the head substrates 16 and 16 in the longitudinal direction. It consists of a pair of left and right sliding substrates 17 and 17 coupled so as to be freely movable, and is formed so as to form a left and right object as a whole. The members 15, 16, and 17 constituting the head plate 2 are made of synthetic resin.

  The support base 15 has a length substantially equal to the thickness when the cleaning member 1 is folded and squeezed in two (see FIG. 12), and both end positions in the length direction thereof. Have two bearing portions 18, 18 and a rod connecting portion 19 for connecting the connecting rods 39, 39 of the operating mechanism 5 at the central position in the length direction. The bearing portions 16 a formed at the base end portions of the head substrates 16 and 16 are coupled to each other so as to be rotatable about a coupling shaft 20 in a direction orthogonal to the length direction of the head plate 2.

  Further, the head substrates 16 and 16 have a substantially flat lower surface. As can be seen from FIG. 4, the lower surfaces of the cleaning members 1 are locked on the lower surfaces of the head substrates 16 and 16. A plurality of locking holes 21A, 21B and a plurality of guide holes 22, 23 for guiding relative movement between the sliding substrates 17, 17 are provided.

  The locking holes 21A and 21B are composed of a wide width portion 21a having a wide hole width and a narrow width portion 21b having a small hole width, and are located near one end in the width direction (short direction) of the head substrate 16. A pair of the locking hole 21A and the second locking hole 21B located near the other end, and two pairs of the locking holes 21A and 21B are located near one end in the longitudinal direction of each head substrate 16 and near the other end. In the position. Then, the locking bullets 11 of the cleaning member 1 are fitted into the locking holes 21A and 21B at the position of the wide width portion 21a, and then the locking bullet pieces 11 are moved to the narrow width portion 21b side. By locking the locking portion 11b with the hole edge of the narrow width portion 21b, the cleaning member 1 is attached so as to straddle the left and right head substrates 16 and 16, as is apparent from FIGS. Yes. The cleaning member 1 is attached to each of the head substrates 16 and 16 while the cleaning member 1 is appropriately bent. The removal of the cleaning member 1 can be performed by the reverse operation of the above attachment.

  As can be seen from FIGS. 4 and 7, the first guide hole 22 among the plurality of guide holes 22 and 23 is formed at the center of each head substrate 16 so as to extend a certain length in the longitudinal direction of the head substrate 16. A short columnar guide shaft 25 formed on the lower surface of each sliding substrate 17 is movably fitted therein, and these head substrates 16 are within the length of the guide hole 22. And the sliding substrate 17 are relatively displaced. Further, the second guide hole 23 is cut in the longitudinal direction of the head substrate 16 from the center position of the head portion of each head substrate 16, and has a plate-like shape formed on the lower surface of each sliding substrate 17 inside thereof. The guide wall 26 is fitted. The sliding substrate 17 and the head substrate 16 can be stably slid by the engagement of the guide holes 22 and 23 with the guide shafts 25 and the guide walls 26.

The sliding substrate 17 is overlapped on the upper surface of the head substrate 16 so as to be freely movable. The length of the sliding substrate 17 is longer than that of the head substrate 16, and therefore the distal end portion 17 a of the sliding substrate 17 in the longitudinal direction slightly extends from the distal end of the head substrate 16. The height is aligned so that the lower surface of 17a and the lower surface of the head substrate 16 are located on substantially the same plane.
On the other hand, in the portion of the sliding substrate 17 that overlaps the head substrate 16, one or a plurality of concave portions and convex portions that extend in the longitudinal direction and are fitted to each other are formed. 16 and 17 are locked together so as not to be displaced in the width direction. However, illustration of these concave portions and convex portions is omitted.

  Further, an edge frame 29 that protrudes slightly downward is formed on the peripheral edge of the lower surface except the base end of the sliding substrate 17, and the connecting plate 10 on the upper surface of the cleaning member 1 is fitted into the edge frame 29. The cleaning member 1 is attached to the head plate 2 in a combined state. At this time, by forming the length of the cleaning member 1 slightly longer than the length of the head plate 2, both ends 1 c and 1 c in the longitudinal direction of the cleaning member 1 are connected to the head plate 2, that is, the tips of the sliding substrates 17 and 17. It is desirable to extend slightly from Thus, the both end portions 1c and 1c of the cleaning member 1 are protruded from the head plate 2 to prevent the head plate 2, that is, the sliding substrates 17 and 17 from coming into contact with walls or furniture during the cleaning and damaging them. It is effective in doing.

  As can be seen from FIG. 1 and FIG. 3, the head support frame 3 has a bifurcated tip, and the sliding substrate 17 connects the connecting arm 31 to the tip of each branch 3a, 3a. Via a swingable connection. The two branch branches 3a, 3a once extend substantially in parallel, and then the tip thereof is inclined so as to be widened. At the tip of the inclined portion, the base end of the connecting arm 31 is connected to the head plate 2. The arm attachment shaft 32 extends in the width direction of the arm attachment shaft 32 so as to be rotatable about the arm attachment shaft 32.

  On the other hand, as can be seen from FIGS. 6 to 8, the lower end portion of the intermediate connector 33 is connected to the bearing portion 17 b on the upper surface of the sliding substrate 17 by a connector support shaft 34 extending in the width direction of the head plate 2. A head that is connected to be pivotable about the connecting tool support shaft 34, and a leading end of the connecting arm 31 extends in the length direction of the head plate 2 to the upper end of the intermediate connecting tool 33. The tilting shaft 35 is connected so as to be rotatable about the head tilting shaft 35. The head tilting axis 35 is perpendicular to the axis L1 of the handle bar 4.

  Therefore, the head plate 2, that is, the wiper head H, can be tilted around the head tilting shaft 35 with respect to the handle bar 4, and when cleaning the floor surface, as shown in FIGS. In addition, the cleaning member 1 can occupy an inclined posture in which the direction of the cleaning member 1 is inclined with respect to the axis L1 of the handle 4. In other words, there is a constant inclination angle θ between the axis L1 of the handle bar 4 and the central axis (head axis) L2 of the wiper head H that penetrates the center of the head plate 2 and the cleaning member 1 in the vertical direction. It is supposed to be kept. At this time, a part of the connecting arm 31 abuts on the bearing portion 17b of the sliding substrate 17 or the intermediate connecting member 33, whereby the wiper head H is positioned at the inclination angle. Although the inclination angle θ of the wiper head H is preferably about 45 degrees, it may be larger or smaller.

  When the floor surface or the like is cleaned, the connecting arm 31 transmits a cleaning operation force transmitted from the handle bar 4 via the head support frame 3 to the head plate 2 via the sliding substrate 17, thereby cleaning the cleaning member. At the time of squeezing 1 (see FIG. 12), the base end portion is supported by the head support frame 3, thereby functioning to apply pressure to the sliding substrate 17 and the head substrate 16 from both sides.

The operating mechanism 5 is connected between the handle 38 and the head plate 2 so that the handle 38 is mounted on the handle bar 4 so that the handle bar 4 can be tilted up and down. It has a pair of left and right connecting rods 39, 39 which are transmitted to the plate 2.
The handle 38 has a grip portion 38 a for raising and lowering an annular shape at the distal end thereof, and the base end portion is rotatably connected to the handle bar 4 by the pin 37. And by raising and lowering with the grip part 38a, the first operation position X at the time of cleaning shown by the solid line in FIGS. 1 and 2 and the second operation position at the time of pressing the cleaning member shown by the chain line in FIG. It is possible to displace between Y. In the first operation position X, the head plate 2 and the cleaning member 1 maintain the extended posture and the inclined posture, and in the second operation position Y, the head plate 2 and the cleaning member 1 are bent (FIG. 12). Reference).

  The connecting rods 39 and 39 are made of a metal wire such as a wire having high strength and rigid elasticity. The connecting rods 39 and 39 extend on both sides of the handle rod 4 substantially in parallel along the handle rod 4 and have base end portions thereof. Is pivotally connected by a support pin 40 between the gripping portion 38a and the base end portion of the handle bar 4, and the tip portion penetrates the inside of the head support frame 3 and is the upper portion of the head plate 2. Thus, the columnar bar connecting portion 19 formed at the center of the upper surface of the support base 15 is connected at the position of the connecting point 41. The connection mode is such that the ends of the pair of connecting rods 39, 39 are bent in a bowl shape toward the inside, which is the direction facing each other, and the bent portion 39a is formed on the end face of the rod connecting portion 19. The locking hole is fitted and locked so as to be rotatable about the longitudinal axis of the head plate 2.

Further, the position of the connecting point 41 of the connecting rods 39, 39 with respect to the rod connecting portion 19 is not the center of the rod connecting portion 19, that is, the center in the width direction of the head plate 2, but the width of the head plate 2 from the center. It is a position that is biased toward one side. Moreover, the position of the connection point 41 is also a position higher than the position of the connection tool support shaft 34 that connects the connection arm 31 and the intermediate connection tool 33, that is, a position closer to the handle 4 side.
On the other hand, the arrangement position of the head tilting shaft 35 is substantially the center in the width direction of the head plate 2. Therefore, the arrangement position of the head tilting shaft 35 and the position of the connection point 41 of the connecting rods 39 and 39 with respect to the rod connecting portion 19 are different from each other in the width direction of the head plate 2.

By arranging the connecting rods 39, 39 and the head tilting shaft 35 in such a positional relationship, when the handle 38 is displaced to the first operation position X when cleaning the floor surface or the like, FIGS. As shown in FIG. 3, the head plate 2 is pushed by the connecting rod 39 and rotated in one direction (clockwise) around the head tilting shaft 35, and the head plate 2 and the cleaning member 1 (ie, the wiper head H). However, it occupies the above-described inclined posture inclined by the angle θ with respect to the handle 4.
Such an inclined posture of the wiper head H is a posture in which the user can efficiently press the cleaning member 1 against a floor surface in a wide area, and the wiper head H is inclined with respect to the handle bar 4. Therefore, cleaning is easier than in the conventional product in which the wiper head H faces the direction of the axis L1 of the handle 4.

  Further, before the cleaning is started or during the cleaning, the handle 38 is moved from the first operation position X to the second operation position Y in order to adjust the water absorption after the cleaning member 1 is impregnated with water. When displaced, in the initial stage of the displacement, as shown in FIG. 9, the head plate 2 is pulled by the connecting rod 39 and rotated in the reverse direction (counterclockwise) around the head tilting shaft 35. Then, the posture is changed so that the inclination angle θ of the wiper head H becomes substantially zero. In other words, the head plate 2 changes its direction so that the cleaning member 1 faces the direction of the axis L1 of the handle 4. At this time, the head plate 2 is positioned in the above-described direction by the distal end portion 31a of the connecting arm 31 coming into contact with the intermediate connector 33.

  Further, due to the further displacement of the handle 38, the head plate 2 is pulled in the direction of the axis L1 of the handle bar 4 by the connecting rod 39 with the post-change posture, and is sequentially shown in FIGS. Thus, the cleaning member 1 is bent for squeezing. That is, as a result of the central support base 15 being pulled up by the connecting rod 39, the head plate 2 is bent in an inverted V shape as shown in FIG. 11, and the cleaning member 1 is bent accordingly. Then, as the handle 38 is further displaced to the second operation position Y, as shown in FIG. 12, the head plate 2 has a pair of head substrates 16 and 16 and sliding substrates 17 and 17 substantially parallel to each other. The cleaning member 1 is sandwiched between the two head substrates 16, 16, and is applied to the head substrates 16, 16 via the sliding substrates 17, 17 by the pressure applied by the connecting arms 31, 31. The cleaning member 1 is squeezed from both sides, and water is squeezed out to adjust the amount of water absorption.

  At this time, as the head plate 2 is bent, the sliding substrate 17 moves relative to the tip end side of the head substrate 16, and the head substrate 16 is moved from the connecting arm 31 through the sliding substrate 17 by the movement. The pressure applied to the cleaning member 1 is adjusted, and an appropriate pressing force is applied to the cleaning member 1 via the head substrate 16. Further, the end portion 1c extending from the head plate 2 of the cleaning member 1 is completely covered with the tip portion 17a of the sliding substrate 17, and the portion is pressurized by the tip portion 17a. The whole will be squeezed reliably.

  The posture or direction of the head plate 2 and the cleaning member 1 during the bending operation is such that the contact area between the two halves of the cleaning member 1 that are pressed against each other is the largest, and the head substrate 16 that acts on the cleaning member 1 and The direction in which the acting force of the sliding substrate 17 is the largest is obtained. By changing the direction of the head plate 2 and the cleaning member 1 in such a direction and then bending and squeezing them, the cleaning member 1 can be efficiently used. It will be squeezed.

  After the pressing operation is completed, the handle 38 is returned to the first operation position X, so that the head plate 2 and the cleaning member 1 are extended and inclined for cleaning, as shown in FIGS. Occupy posture.

  The handle 38 has a locking device 42 that locks the handle bar 4 at the first operation position X. As shown in FIG. 10, the locking device 42 is composed of a pair of elastic locking pieces 43 and 43 extending from the intermediate position of the handle 38 toward the handle bar 4 side. A concave groove 43a is formed on the inner surface of each stop piece 43, and the handle bar 4 is elastically fitted between the elastic locking pieces 43, 43 at the first operation position X, thereby forming the concave groove 43a. The handle 38 is configured to be held at the first operation position X by being locked.

  Further, as described above, the wiper can be wiped and cleaned by directly pressing the cleaning member 1 against the floor surface or the like. However, as shown by a chain line in FIG. It can also be cleaned by wearing. Therefore, as can be seen from FIG. 7, the head plate 2 is provided with fastening mechanisms 46 for fastening the wiping sheet 6 at the positions of both end portions in the length direction.

  The fastening mechanism 46 is composed of a clip 47 having an elongated arm shape that can be freely opened and closed. The clip 47 is inserted into a locking groove 48 formed at both ends of the upper surface of the head plate 2 and its base end portion 47a. With the tip 47b facing the end side of the head plate 2 and extending in the length direction of the head plate 2, and the base plate The end portion 47 a is connected to the groove wall of the locking groove 48 so as to be rotatable about a clip support shaft 49 facing the width direction of the head plate 2. A finger hook portion 47 c for opening and closing operation is formed at the tip portion 47 b of the clip 47, and an elastic locking piece 47 d is formed. This locking piece 47 d is connected to the bottom of the locking groove 48. It can be elastically engaged with and disengaged from the protruding locking portion 48a formed at the tip of the wall.

The wiping sheet 6 is attached to the cleaning member 1 in a state where the clip 47 is rotated to the open position as shown by a chain line in FIG. 7, and after the wiping sheet 6 is attached, the clip 47 is attached to the solid line in FIG. By rotating to the position, the wiping sheet 6 is sandwiched between the clip 47 and the head plate 2 in the locking groove 48, and the elastic locking piece 47 d at the tip of the clip 47 is locked to the locking groove 48. The locking portion 48a is elastically locked, and the clip 47 is held in that position.
Thus, by cleaning the wiping sheet 6 by attaching the wiping sheet 6 to the cleaning member 1, water is gradually and continuously supplied from the cleaning member 1 to the wiping sheet 6, thereby eliminating the trouble of replenishing water frequently. Efficient cleaning with water can be performed.
Even with the wiping sheet 6 mounted on the cleaning member 1, it is possible to perform a water absorption operation or an operation for adjusting the water absorption amount to the cleaning member 1.
