Description

The present invention relates to a mop squeezer.

The conventional mop squeezer is a water tank integrated type, and for squeezing, the handle of the mop is supported upward with one hand and the lower handle is rotated with one hand. Alternatively, the squeezing roller was held by stepping to raise the mop handle.
JP 2001-29304 A

However, the conventional mop squeezer has to have a combined weight of water and a squeezing device sufficient for washing water exchange, which is inconvenient for the body. In addition, a squeezer that squeezes the mop with a foot while holding the squeeze roller and holding the mop handle upward with one hand and rotating the lower handle with the other hand was difficult and painful. Or, in order to ease the pulling force, the diaphragm that holds the squeezing roller by stepping and pulling up the handle of the mop has had problems such as weakening the foot and making the diaphragm loose so that it cannot function as a diaphragm. Furthermore, the force to squeeze was not constant, and it was difficult to always maintain the desired water content.

The mop squeezer of the present invention squeezes the mop cloth between the movable roller 2 and the passive roller 3 by narrowing the squeeze on the front side of the base 1 so that the push rod 23 connected to the movable roller 2 is the rear side of the base 1. There is a raising / lowering plate 6 that forms a crank mechanism that pressurizes the spring 4 provided on the rear side of the base 1 and moves the push-pull bar 23, and is pivotally supported by the raising / lowering plate 6. The push bar 23 connected to the arm bar 62 and the movable roller 2 has a mop throttling mechanism that is screwed in such a manner that the length can be adjusted, and when the step board 9 on the rear side of the base 1 is depressed, it is linked to the depression. The endless transmission body 83 that is interlocked and connected is supported by the rotating body 8 and rotates into an oval shape, and the lifting rod 7 connected to the endless transmission body 83 that moves in the direction opposite to the tread plate 9 rises and interlocks with the lifting rod 7. While mop is movable roller 2 and passive roller Having a push-up mechanism to be discharged from.

Since the mop squeezer of the present invention is not integrated with the water tank, a bucket or an appropriate container can be used in the water tank, and only the bucket or the container needs to be carried for replacement of the washing water, thereby reducing the weight and reducing the work load. In addition, since the mop cloth squeezed by stepping on the tread board is discharged from the pair of rollers, an unnatural posture and a handle turn or pulling of the mop handle are unnecessary, and the burden on the body is greatly reduced. Furthermore, since the adjustment of the opening width, the adjustment of the spring pressure, and the movement of the spring can be performed, it is possible to deal with mop cloth of various thicknesses and to freely set the water content. Since it is only a throttle mechanism and a discharge mechanism separated from the water tank, it is small and light and convenient for carrying and storing.

  Hereinafter, an embodiment of a mop squeezer according to the present invention will be described with reference to the drawings.

  As shown in FIGS. 1 to 12, the mop squeezer according to the present embodiment has a movable roller 2 and a passive roller 3 that press the mop cloth on the front side of the base 1 in parallel with the base 1 and is movable. The roller 2 is rotatably supported on the movable roller bearing 21. A movable roller support plate 22 is also pivotally supported on a shaft between the movable roller bearing 21 and the movable roller 2 so as to be rotatable. The other end of the movable roller support plate 22 is pivotally supported on the side surface of the base 1 so as to be rotatable.

  As shown in FIGS. 7 and 8, the movable roller bearing 21 is connected to a push / pull bar 23 extending to the rear side of the base 1, and when the push / push bar 23 is pushed forward by a crank mechanism described later, the movable roller 2. Moves the movable roller support plate 22 forward in the radius. The passive roller 3 is pivotally supported by the passive roller support plate 31 at a position where the movable roller 2 contacts when the push rod 23 is pulled back by a crank mechanism described later. The passive roller support plate 31 is fixed to the base 1.

  As shown in FIG. 3, the shaft screw 5 is connected to a shaft screw support plate 51 fixed to the center upper portion on the rear side of the base 1. The shaft screw 5 penetrates the spring 4 and sandwiches the spring 4 so that the spring 4 can be moved back and forth. The shaft screw 5 penetrates slidably, the rear plate 54 having a substantially U-shape is slid at the rear portion of the spring 4, and a rear nut 55 (for example, a nut below) is pivoted. 5 penetrates.

  As shown in FIG. 9, a substantially U-shaped raising / lowering plate 6 is fitted at the center of both ends of the rear plate 54, and both the left and right ends of the rear plate 54 and the left and right ends of the raising plate 6 are rear plate screws. 56 is rotatably supported. The top plate of the raising and lowering plate 6 has a concave shape. When the raising and lowering plate 6 is tilted backward, the shaft screw 5 is fitted in the recess. Arm bars 62 are pivotally supported on both side plates of the tilting plate 6 at the top of the left and right ends by pivotal plate screws 61 so as to be pivotable to the left and right, and a lever 63 is fixed to the top plate of the tilting plate 6. ing.

  1, when the lever 63 is tilted forward as shown in FIG. 1, the raising and lowering plate 6 also falls forward, and the arm bar 62 pivotally supported by the raising and lowering plate screw 61 moves forward to the arm bar 62. A push-pull bar 23 screwed in a form in which the length can be adjusted with a length adjusting screw (for example, a thumbscrew) is supported by the movable roller support plate 22 and moves forward and obliquely downward. At the same time, the movable roller 2 also moves forward and obliquely downward. The movable roller 2 and the passive roller 3 are separated by this crank mechanism, and a mop cloth is inserted therebetween. Since the width between the two rollers is adjusted by adjusting the length of the push-pull bar 23 with the wing screw 24, it can be adjusted with the wing screw 24 according to the thickness of the mop cloth.

  As shown in FIG. 8, when the lever 63 is tilted backward, the tilting plate 6 also tilts backward, and the arm bar 62 pivotally supported by the tilting plate screw 61 is moved rearward by this crank mechanism. The push rod 23 screwed with the screw 24 is supported by the movable roller support plate 22 and moves backward. At the same time, the movable roller 2 also moves backward and contacts the passive roller 3.

  The raising and lowering plate 6 and the push-pull bar 23 can be locked by making the horizontal position of the raising and lowering plate screw 61 slightly lower than the horizontal position of the rear plate screw 56. The reason why the top plate of the raising and lowering plate 6 is concave is that the position of the raising and lowering plate screw 61 is hung on the lower shaft screw 5 and locked. In addition, it can be used for the front nut 52 and the rear nut 55 by attaching the ratchet with a nut shown in FIG. 14 downward.

  From the above structure, when the thick mop cloth or the mop cloth containing a large amount of moisture is thick, the movable roller 2 is moved forward by rotating the thumbscrew 24 to move the movable roller 2 and the passive roller 3. If the distance between the movable roller 2 and the passive roller 3 is reduced, the distance between the movable roller 2 and the passive roller 3 may be reduced.

  When the raising / lowering plate 6 is locked rearward as shown in FIG. 3, the interval between the movable roller 2 and the raising / lowering plate screw 61 is determined by the position of the thumbscrew 24, and the spring 4 is compressed until the interval is reached. The plate 6 is locked. The compression force of the spring 4 becomes a clamping pressure. There are two methods for adjusting the clamping pressure, and one is adjusted only by the position of the thumbscrew 24. That is, when the thumbscrew 24 is rotated and moved forward, the spring 4 is further compressed and the clamping pressure is increased. When retracted, the spring 4 loosens the compression and the clamping pressure becomes weaker. For example, when the distance between the movable roller 2 and the passive roller 3 is kept constant, that is, when the position of the thumbscrew 24 is maintained, the clamping pressure is adjusted at the position of the front nut 52. When the front nut 52 is rotated and moved forward, the spring 4 is also moved forward, the compression of the spring 4 is weakened, and the clamping pressure is weakened. When the front nut 52 is retracted, the compression of the spring 4 is increased and the clamping pressure is increased. Thus, the clamping pressure can be adjusted according to the thickness of the mop cloth, and the clamping pressure can be adjusted even when the opening width between the movable roller 2 and the passive roller 3 is maintained. The spring 4 can be moved by rotating the front nut 52 and the rear nut 55, and the adjustment range of the clamping pressure is widened.

  A mop diaphragm mechanism having the above-described configuration is provided.

  As shown in FIG. 2, there is a lifting bar 7 on the rear side of the base 1 for squeezing and discharging from the movable roller 2 and the passive roller 3 that pinch the mop cloth, and a mop hook 71 is attached to the tip of the lifting bar 7. It is fixed in an easy-to-hang form. The tip of the mop hook 71 is pointed so that it can be easily put into the mop cloth, and is provided with a recess for hanging the mop frame.

  As shown in FIG. 6, the lifting rod 7 has a substantially U-shape, passes through a lifting rod frame 72 fixed to the base 1, and a return spring 75 is screwed to the lower end.

Each side plate 86 has a mounting plate 87 for fixing to the base 1 on the surface in contact with the base 1, and a lifting bar push guide 73 is provided on the upper part of the lifting bar 7 to stabilize the vertical movement of the lifting bar 7. A slide plate guide 85 is provided at the lower portion, and a tread plate guide 92 is provided at the upper portion of the slide plate 84 from the upper end to the lower end. The width of the mounting plate 87 is one half of the width of both outer surfaces of the left and right pulley shaft support plates 82 sandwiching the pulley 8 in a freely rotatable manner, and the width of the slide plate guide 85 and the tread plate guide 92 is the pulley shaft support plate. This is the same as the width of 82. The lifting bar screw 74 and the footboard screw 91 move up and down freely in the central space when the side plate 86 is composed of two pieces that are aligned left and right. The slide plate 84 is inserted between the slide plate guide 85 and the tread plate guide 92 of the left and right side plates 86 so as to move up and down freely.
