DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below in detail with reference to the drawings showing embodiments.

FIG. 1 is an external perspective view showing an embodiment of the present invention. A mop drawing machine according to the present invention comprises an operating section 30 at an upper portion thereof and a receiving portion 31 disposed at a lower portion thereof. Consisting of
The operation unit 30 is detachable from the receiving unit 31. The operation unit 30 is provided with a first roller 1 for narrowing a mop 32 (see FIG. 9 and the like) and a second roller 2 disposed in parallel with the first roller 1.

On the other hand, a container 26 for receiving dirty water squeezed out of the mop 32 is built in the receiving portion 31, and a front wheel 28 with a manually operated brake 27 is provided at the lower front and rear both sides of the receiving portion 31. , 28 and rear wheels 29, 29 are provided.
A carry handle 33 for moving operation is provided.

FIGS. 2 and 3 show the structure of the main part of the operation unit 30. In these figures, reference numeral 7 denotes a main body frame. The support shaft 1a is slidably inserted through the receiving holes 9, 9 formed in the elongated holes, and the first roller 1 is rotated through the support shaft 1a via the dry bearings 11, 11. The shaft 1a is freely supported, and both ends of the support shaft 1a are fixed to one ends of link members 12, 12, which constitute a link mechanism, as described later.

On the other hand, at both ends of the shaft portion 2a integrally fixed to the second roller 2, slide shaft portions 2b, 2b formed in a round bar shape are formed, and one side (right side) of the slide shaft is provided. At the outer end of the portion 2b, a square shaft portion 2c is formed. The two sliding shafts 2b, 2b are formed on the front left and right side surfaces of the main body frame 7 as receiving holes 1 formed in a long hole shape in the front-rear direction.
0, 10 and long holes 82, open rearward in the front and rear directions on the double walls 81, 81 of the adjusting frame 8 disposed on both outer sides thereof.
82 and a shaft hole 34a of a bearing member 34 urged rearward by a resilient member (coil spring) 35 in each double wall 81 thereof.
And is rotatably supported via a dry bearing 11.

Further, one (right) slip shaft portion 2b
Is slidably and freely inserted through a receiving hole 19 formed in a long hole shape in the front-rear direction when opened downward at a position corresponding to the upper lid 18 which can be opened and closed vertically, and extends outward from the receiving hole 19. The base end of the manual handle 6 is detachably fitted into the square shaft portion 2c protruding (to the right). At its base end, a one-way clutch 36 composed of a ratchet mechanism is built in,
Only in one direction (M direction in FIG. 2), that is, the mop 32 (FIG. 2)
10) can be transmitted from the manual handle 6 to the shaft 2a only in the direction in which the squeezing is performed. (Of course,
If the right and left holes at the base end of the manual handle 6 are reversed and fitted outside the square shaft portion 2c, switching can be performed so as to transmit the rotational force only in the direction opposite to the arrow M in FIG. )

The adjustment frame 8 has double walls 81, 81 formed on both sides integrated with a left-right front plate 83, and is formed in a substantially U-shape in plan view. Double wall
81, 81 are arranged between the side wall of the main body frame 7 and the side wall of the upper lid 18 with a slight gap therebetween, respectively, and the front plate 83 is connected to the front wall 7b of the main body frame 7 and the upper lid 18 Front wall 18
The adjustment frame 8 is disposed between the main frame 7 and the upper lid 18 so that the relative position of the adjustment frame 8 can be adjusted in the front-rear direction.

More specifically, adjustment knobs 17 with screw shafts,
17 is fitted with spacers 22 and 22 and its screw shaft is
From the outside, the screw shafts are inserted into the openings 8a, 8a formed in the front plate 83 of the adjustment frame 8, and from the openings 8a, 8a. The return springs 16 and 16 are fitted on the protruding portions, and their screw shafts are screwed into nut members 15 and 15 welded to the front surfaces of holes formed in the front wall 7 b of the main body frame 7.

With such a configuration, the adjustment knobs 17,
By rotating the 17, the adjustment frame 8 can be moved back and forth, whereby the first roller 1 (indicated by a two-dot chain line in FIG. 3) that has been moved to the working position can be moved.
By adjusting the relative position (interval) of the second roller 2, it is possible to adjust the pressure applied to the mop 32.

When adjusting the clamping pressure, when the mop 32 itself is thick or when the mop 32 contains a large amount of water and the mop 32 is thick, the adjustment knobs 17 and 17 are rotated to adjust the adjustment frame. 8, the second roller 2 is advanced (downward in FIG. 3) to increase the distance between the first roller 1 and the second roller 2, and when the mop 32 is thin or the moisture is considerably reduced, the mop 32 When it becomes thin, the second roller 2 may be retracted (in the upward direction in FIG. 3) to reduce the distance between the first roller 1 and the second roller 2.

In the meantime, the second roller 2 is constantly urged by the resilient members 35 in the adjustment frame 8 in a direction (rearward) to approach the first roller 1. Therefore,
Even if the distance between the rollers 1 and 2 changes, a constant urging force always acts on the second roller 2, and no excessive clamping force acts on the thick mop 32. Also, a sufficient clamping force can be applied to the thin mop 32.

By adjusting the distance between the rollers 1 and 2 by the adjusting knobs 17 and 17 as described above, it is possible to flexibly cope with the thickness of the mop 32 and the degree of water contained therein. Can stabilize the action and mop
32 can be squeezed out smoothly without difficulty. In addition,
If the clamping force on the mop 32 is insufficient during the operation of the squeezing operation by operating the manual handle 6,
The spacing between the rollers 1 and 2 may be reduced by rotating the adjustment knobs 17 and 17 as appropriate, and the spacing between the rollers 1 and 2 may be increased if the clamping force is too large. .

For example, as shown in FIG. 4, the spacer 22 is provided with different colored marks in the axial direction (front-back direction).
, The distance between the rollers 1 and 2 can be checked at a glance from the front working position, and the usability is further improved. For example, blue is assigned, yellow is assigned, and red is assigned. When the mop 32 is thick, the adjustment is performed around blue, and when the mop 32 is thin, red is used as a guide.

Further, by providing the adjustment frame 8, the second roller 2 can be maintained in a normal state without tilting the second roller 2 with respect to the first roller 1. More specifically, as is apparent from FIG.
However, between the side wall of the main body frame 7 and the side wall of the upper lid 18,
Since the two double walls 81, 81 of the adjusting frame 8 moving back and forth are guided by the side wall of the main body frame 7 and the side wall of the upper lid 18 by being disposed with a slight gap therebetween, This is because the inclination is regulated.

On the other hand, one ends of link members 12, 12 are fixed to both ends of the support shaft 1a of the first roller 1, and the other ends of the link members 12, 12 protrude from the rotating arms 13, 13. The pivot arms 13 are pivotally connected to the shaft portions 7a protruding from the rear ends of the main body frame 7, respectively. And the two rotating arms 1
The connecting rods 3 and 13 are integrally and strongly connected by two connecting rods 14 and 14, and a base of the switching lever 3 is fixed to an end (right side when viewed from the front) of one connecting rod 14. I have.

By such a link mechanism, a positioning mechanism 4 for positioning the first roller 1 at the working position is formed, and by swinging and operating the switching lever 3 back and forth, the rotating arms 13, 13 are moved. The shaft 1a rotates around the shaft portions 7a and 7a, and the support shaft 1 of the first roller 1
a is slid back and forth along the receiving hole 9 so that the second roller 2
, The first roller 1 moves toward or away from it. In addition,
By forming the receiving hole portion 9 in an inverted letter shape,
The sliding operation at the time of starting the support shaft 1a of the first roller 1 becomes smooth, the resistance at the time of operating the switching lever 3 is reduced, and the operation becomes easy. When the switching lever 3 is tilted forward, the first roller 1 is fixed at the working position indicated by the two-dot chain line in FIG.

The positioning mechanism 4 will be described. First, in a state where the first roller 1 is not used (standby state), the switching lever 3 is vertically erected as shown in FIG. The support shaft 1a is located at the rear end of the receiving portion 9, and the first roller 1 is located at the standby position farthest from the second roller 2. At this time, the rotating arm 13 is about to be rotated clockwise by the weight of the switching lever 3, but the rear connecting rod 14 fixed to the rotating arm 13 is
The rotation arm 13 is brought into contact with and locked to the upper surface of the main body frame 7 and rotation of the rotation arm 13 in the same direction is restricted. Therefore, the switching lever 3
Is stably held, and the first roller 1 is also
It is stably held at the standby position.

When using (working), as shown in FIG. 6, the first roller 1 can be moved to the forefront working position and stably fixed by tilting the switching lever 3 forward. More specifically, when the first roller 1 is moved to the working position via the link member 12 by the switching lever 3, the resilient members 35, 35 are compressed via the mop 32,
As shown in FIG. 7, the axis A of the support shaft 1a of the first roller 1 to which one end of the link member 12 is pivotally connected, and the axis (with the main body frame 7) to which the rotation arm 13 is pivotally connected. The other end of the link member 12 is pivotally connected to the axis E of the shaft 13a (attached to the rotating arm 13) to a position lower than the straight line E connecting the axis B of the part 7a. I do. That is, the point where the trajectory F of the axis C intersects with the straight line E is the dead point D of the link mechanism, but the pivot point (axis C) between the link member 12 and the rotating arm 13.
Is in a position below the dead center D.
When the dead center D is exceeded, the resilient members 35, 35 (shown in FIGS. 2 and 3) are once more slightly compressed.

At this time, the rotating arm 13 tries to rotate counterclockwise due to the weight of the switching lever 3 that has been tilted forward, but both connecting rods 14, 14 abut on the upper surface of the main body frame 7. It does not rotate downward (counterclockwise) any more because it contacts and locks. In this state, during the squeezing work of the mop 32, the urging force of the resilient members 35, 35 causes the second
Even when a reaction force acts on the link member 12 from the roller 2 via the mop 32 in the right direction in FIG. 7, the pivot point (axis C) between the link member 12 and the rotating arm 13 is maintained. , The rotating arm 13 does not rotate clockwise since it is located below the dead center D. Thereby, the state where the first roller 1 is stably held at the illustrated working position is maintained.

On the other hand, when the switching lever 3 is lifted upward, the axis C climbs over the dead center D. At this time, the resilient members 35 are once further compressed. It can be returned to the standby position. The first roller 1 is stably fixed and held at the working position as long as the switching lever 3 that is tilted forward is not lifted.

On the other hand, since the second roller 2 is connected to the manual handle 6 via a one-way clutch 36 comprising a ratchet mechanism or the like, as shown in FIG. 8 (and FIGS. 6 and 10), the mop 32 With the manual handle 6
The second roller 2 can be rotated in the direction of the arrow M (counterclockwise) only when it is swung in the downward direction L when it is swung in the upward direction K. On the other hand, since the first roller 1 is freely rotatable and fixed at its working position (the movement in the vertical direction is restricted), the mop moved upward by the second roller 2. Receives a reaction force from 32 and turns around in the direction of arrow G (clockwise), mop
32 is squeezed while being pushed upward. Therefore, the mop 32 can be pushed up from the main body while squeezing the mop 32 simply by moving the manual handle 6 up and down.

With the above-described configuration, in use, first, the brake 27 is operated (by hand or foot) to apply a brake to the front wheel 28 and stably fix the main body. Next, the adjusting knobs 17 and 17 are rotated to move the mop 32.
The gap between the two rollers 1 and 2 (clamping pressure) is adjusted in advance according to the thickness of the roller. Then, the wet mop 32 is inserted between the rollers 1 and 2 to the vicinity of the base (see FIG. 9),
After the first roller 1 is moved from the standby position to the working position by tilting the switching lever 3 forward, the mop 32 can be pushed upward while squeezing the mop 32 by operating the manual handle 6 up and down (see FIG. 10). ). After the squeezing operation is completed, as shown in FIG.
The squeezed material 24 such as water squeezed inside may be drained to the outside.

As described above, the operator holds the switching lever 3, the adjustment knobs 17, 17 and the manual handle 6 at a position in front of the main body.
And the like, and the operation of the switching lever 3 requires only a small amount of labor due to the principle of leverage, and can perform the squeezing work of the mop 32 in an easy posture with extremely good workability. . In addition, the gap (pressing force) between the rollers 1 and 2 can be adjusted by the above-described adjustment knobs 17 and 17 according to the thickness of the mop 32 itself, the state of water contained in the mop 32, and the like. In addition, the left and right balance state of the second roller 2 with respect to the first roller 1 is stably maintained by the adjustment frame 8, so that a good throttle action can always be exhibited stably. The present invention is not limited to the above-described embodiment. For example, the manual handle 6 and the second roller 2 may be interlocked and connected via a speed reduction mechanism having gears. May be a circular shape, and the design can be freely changed as appropriate without departing from the gist of the present invention.

FIG. 13 shows another embodiment. In this case, for example, a pail 38 is placed on a frame 37 with a carry, and an operating section is placed on a mounting portion 39 provided at the top of the frame 37. 30
Only the set is used, and the squeezed sewage is received by the pail 38 disposed immediately below. In addition, although not shown, a bucket for storing sewage and a bucket containing fresh water are placed on a frame with a carry, and once mopted.
After washing 32 with fresh water, the squeezing operation may be performed. Further, a bucket may be arranged under a fixed mounting base on which the operation unit 30 can be mounted in a stable state.
When performing a large-scale cleaning, only the operation unit 30 may be arranged on a sink, and a method of using the operation unit 30 may be appropriately selected.

[0031]

Since the present invention is configured as described above, the following effects can be obtained.

(According to claim 1) The manual handle 6
By the operation described above, the squeezing operation of the mop 32 can be performed in a comfortable posture with good workability. Moreover, the adjustment frame 8
Thus, the left and right balance state of the second roller 2 can be stably maintained with respect to the first roller 1 fixed at the working position, and a good throttle action can always be exhibited stably.

Second roller 2 (according to claim 2)
In addition, since the manual handle 6 is attached via the one-way clutch, the mop 32 can be squeezed with good workability only by swinging the manual handle 6 up and down.
