Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a mopping device used with wet mopping, and more particularly to a mopping device such as a mopping bucket combined with a wringer having two squeezing rollers. .

In this device, the mop is pulled upwardly between two squeezing rollers for squeezing.

(Prior Art) Devices such as those described above are commonly used, and the most common configuration is equipped with an upwardly projecting operating lever, which allows the motsupu to be inserted into the wringer and then , so that squeezing pressure can be applied. The aperture operation is performed by two hands. That is, - it is required that one hand operates the lever and the other hand pulls the motsu through the wringer. Foot-operated devices are also available, but they have the disadvantage of requiring the use of both feet. That is, one foot must operate the closure mechanism and the other foot must hold down the bucket. In both cases, continuous pressure must be applied to the actuating member by hand or foot in order to maintain the desired throttling pressure.

It is an object of the present invention to provide a foot-operated mop device designed to be able to apply a predetermined squeezing pressure using only wooden legs.

According to an aspect of the invention, a mopping device comprises a wringer with a plurality of wringer rollers mounted on the top of a bucket, and an actuation mechanism consisting of a foot-operated pedal and a toggle link located below said bucket. The actuating mechanism is configured to cause the squeezing roller to perform a relative closing operation and bring it into an overcenter state by pressing a foot-operated pedal, and to provide a predetermined gap between the squeezing rollers at the squeezing operation position. lock. A predetermined squeezing pressure is then applied to the mop of a predetermined thickness, and this pressure is independent of the pressure applied by the foot.

When the other or rear roller performs the relative closing motion described above by means of two similar toggle links connecting each end of said roller and a foot-actuated pedal, said roller (the one that is not the rear roller) closes the bucket. Preferably, it is rotatable about an axis in a fixed position on the front side. Each toggle link has a projection that is engageable and movable by a foot to release the toggle link and move the rear roller to an open position toward the rear of the bucket. This rear roller may be spring biased into the open position or moved into the open position by foot pressure applied to the protrusion.
I can do that. Alternatively, a return spring acts to bias each toggle link into the open position, and the squeezing pressure during mop squeezing maintains each toggle link in an over-center locked position, allowing the mop to move between the rollers. After being pulled up and removed from the rollers, the spring can also be actuated to return the actuating mechanism and rear roller to a non-operating, rest position.

In order to adjust the gap between the rollers in the squeezing position to a predetermined amount, to adapt to different thicknesses of mopping heads, or to adapt to the physical strength of the user and the desired workload, there is a movable rear part in the actuating mechanism. There may also be an adjustable coupling member for each end of the roller. Each coupling member may include a lever connected to a rear roller near one end and connected to an actuation arm of an actuation mechanism at an intermediate portion. This lever engages the axis of rotation of the arm at a distance from the roller by means of an adjustment thumbscrew screwed into the arm. Alternatively, the axis of rotation of the rear force roller may be fixed to the actuation arm of the actuation mechanism, and the position of the axis of rotation of the front roller relative to the bucket may be adjustable.

Preferably, the foot-operated pedal is located below the roller in the throttle position and in a recess at the front of the bucket.

The pressure applied to the pedal counteracts the upward pulling force applied to the squeezed mop and provides the optimum aid for firmly resting the device on the floor.

The bucket is generally plastic molded, for example from polypropylene, and can have a cross-sectional shape that provides shelves on either side of the upper opening and from which the ends of the two rollers protrude. In addition, the rollers are longer than the liquid containing portion of the bucket so that the mop strands are separated from the ends of the rollers and do not become entangled with the roller mechanism. If the shelf is formed at the bottom of the groove, and its depth is at least equal to the diameter of the roller,
The rollers are placed on the underside of the bucket rim to prevent splashing.

Preferably, the bottom of the bucket is held at a predetermined distance from the floor. This allows for the necessary pedal travel and foot pedal access even though the bucket recess is small, increasing volumetric efficiency. For this purpose, corner sockets at the bottom of the bucket may be molded, and casters or, if desired, "glider" shaped legs may be mounted within the sockets.

(Embodiment) First, a mopping device according to a first embodiment of the present invention will be described.

As shown in FIGS. 1 and 2, the mopping device of this embodiment includes a molded plastic bucket 1 generally having a capacity of 24 liters, and a bucket 1 arranged so as to be rotatable laterally with respect to the bucket 1. The apparatus includes a wringer combined with a bucket 1 having two wringer rollers 2.3. The roller 2 is fixed laterally in a predetermined position on the front side of the bucket 1, while the roller 3 is moved by an actuating mechanism 4 between the open position shown in FIG. 1 and the closed position for squeezing action shown in FIG. is set up so that it can be moved. The bucket 1 has two pail handles 5 (one of which is shown partially cut away in FIG. 2), which allows the user to carry the device.

Bucket 1 also has a false glider (f) at each corner of its bottom.
It has four legs 6 in the form of an alse glider: a device for facilitating movement. These legs 6 support the bucket 1 in such a way that its bottom is lifted off the floor. The legs 6 are attached to corner sockets 7 molded into the bucket 1. The legs 6 slide fairly freely on a moderately smooth floor. Note that if casters having the same effective height as the legs 6 are inserted into the sockets 7 instead of the legs 6, mobility can be improved.

At the bottom edge of the thin side of the bucket 1, a central recess 9 is molded into the vertical surface of the bucket 1, and a foot actuating pedal 8 of the actuating mechanism 4 is located at the bottom of this recess 9.
are arranged. This pedal 8 is a U-shaped pedal par I
It is attached to O. The pedal parlO has two lateral rims which extend along each side of the bucket 1 and are connected via toggle links to two actuating arms 11 connected to both ends of the roller 3, respectively. There is.

There are two sets of toggle links on both sides of the bucket 10.
The right-hand side mechanism is shown in FIGS. 1 and 2. This mechanism will be explained below.

A bracket 12 is attached to the side of the bucket 1 along the bottom edge of the bucket 1 and supports a bot 13 for the lateral rim of the pedal parlO. The actuation arm 11 is rotatably mounted on the bracket 12 at a position indicated by 14 (behind the pivot 13), and the toggle link includes an end 15 of the pedal parlO and a rotation link 16. The rotary link 16 is rotatable at both ends with respect to the end of the end portion 15 and with respect to the arm 11, respectively.

To squeeze the mop, the mop is inserted into the bucket 1 so that it hangs between rollers 2 and 3. At this time, the roller 3 is in the open position shown in FIG.

Pressing the pedal 8 then moves the roller 3 to the closed position shown in FIG. 2, and the end 15 and rotating link 16 move to the over-center locked position. This locked position is determined by engagement of a stopper (not shown) with the end portion 15. This state of the toggle link provides a predetermined spacing between the rollers 2.3 such that a squeezing action takes place when the mop is manually pulled upwards between the rollers 2.3.

After the mop has been squeezed, the toggle link can be released and the roller 3 returns to the open position by foot pressure applied to the joggle 17 of the end 15. Bucket 1
Each toggle link provided on each side of the roller 3 is preferably released by foot force before the roller 3 returns to the open position.

The bucket 1 has a flat front vertical section in which a recess 9 is formed, and the pedal 8 has a roller 2 when in the closed position shown in FIG.
and 3. By placing the foot on the pedal 8, when the user squeezes the mop and pulls it upward, a downward force directly opposing the upward pulling of the mop is applied.

The connection between each end of the rollers 3 and the corresponding actuating arm 11 allows the gap between the rollers to be adjusted in the closed position shown in FIG. Each end of the roller 3 rotates at the forward end of a lever 18 which is rotatably mounted to the actuating arm 11. A thumbscrew 19 screwed into the actuation arm 11 engages with the rear side of the lever 18, and the actuation arm 11
provides means for adjustment of the position of the axis of the roller 3 relative to the upper end of the roller.

Concave grooves 20 are molded at the upper ends of the front part and both side parts of the bucket 1. The roller 2 is positioned within the groove 20 so as not to substantially block the upper opening of the liquid storage portion of the bucket 1. The lateral part of the groove 20 provides a ledge 21 above which the end of the roller 2.3 projects. This shelf 21 prevents the inserted mop strands from approaching the ends of the rollers 2.3 and, in particular, prevents the strands from becoming entangled with the actuating mechanism. Therefore, there is no need for a separately fitted "sliga" used in conventional devices, in order to keep the ends of the mop strands away from the outside of the ends of the rollers. This allows the roller 2.3 to be placed under the rim of the bucket 1 to prevent splashing.

Next, a second embodiment of the present invention will be described with reference to FIGS. 3 to 7. Since the basic configuration has already been described, elements corresponding to those in the first embodiment are indicated by adding 100 to the reference numeral. The essential differences between the two embodiments will be explained below.

The movable rear roller 103 has two actuating arms 11
1 , while the front fixed roller 102 is connected at each end to the bucket 101 so as to be rotatable about a lateral fixed axis defined by an adjustable mounting member 122 . hand .

There is. As shown in FIGS. 5 to 7, the mounting member 12
2 are each adjustable along each slot 123 in the hollow rim region 124 of the bucket 101, and each has a thumbscrew 119, a nut 125, and a roller 102.
and a stirrup-like member 126 which is rotatably mounted. Region 127 is rim region 1 near each slot 123.
24 and are similarly serrated for engagement with the serrated upper surface of each nut 120.

3 and 4, the actuation mechanism 104 has actuation arms I11, each actuation arm Ill having a slot 128 located in a projection 129 projecting inwardly of the shelf 121.
extends through. Pedal par 110 is bucket 101
The stirrup-like foot-operated pedal 108 is rotatably attached to a bracket 112 fixed to the rotating shaft 13.
It is rotatably attached to one end of each lever 110 at 0. The upper end of the return spring 131 is attached to a set nail (veg) 132 on each lever 110, and the lower end is attached to a notch 133 in each bracket 112. A stop 134 is attached to each rotating link 116 to limit movement of actuating mechanism 104 in an overcenter toggle position that defines the closed position of roller 103. Each socket 107 provided at the bottom corner of the bucket 101 accommodates a caster 135, which is a floor support member.

The second embodiment operates in substantially the same manner as the first embodiment. However, the front roller 102 is adjustable and the spring 131 acts to return the rear roller 103 to the open position (inactive rest position). Pressing foot-actuated pedal 108 moves roller 103 to an operating (closed) position adjacent to roller 102 and spaced a predetermined distance from roller 102 such that rotary link 116 is over-centered with respect to lever 110. The movement of this link 116 is limited by a stop 134. When the foot pedal 108 is released, the spring 131 acts to return the rotary link 116 to its rest position, which requires the roller 103 to move closer to the spacing roller 102 as the link passes over-center. Motsupu wo roller 10
3, the roller 103 cannot move closer to the roller 102 under the restoring force of the spring. The restoring force of the spring is significantly less than the reaction force to the throttling pressure exerted on the mop, so that the rotating link 116 remains in an overcenter position until the mop leaves the rollers 102, 103. Therefore, the pressure on the pedal 108 is
does not need to be held to keep it in operating position. Once the mole is removed and the foot pedal 108 is released by the user, the action of the spring 131 causes the roller 103 to return to the open position. The adjustable gap between the rollers 102, 103 determines the squeezing pressure for a given mop thickness based on the use of the actuation mechanism 104. This pressure is applied to roller 1
02. From 103, when one bow is extended, bucket 101
It is not affected by the pressure of the foot applied to hold it down.

The upper part of the depression 109 is the inclined part 13 at the bottom of the bucket 101.
6. Dirt, particles, etc. collected by the mop or removed during squeezing the mop slides down the slope 136 and is collected in a dirt sump 137 at the rear of the bucket 101. A removable prill or plate 13B is provided on the dirt collection section 137, and a mop is provided on the dirt collection section 137.
7. Prevent the picking up of garbage etc.

(Effects of the Invention) As described in detail above, according to the present invention, it is possible to squeeze the mop with a preset squeezing pressure using one leg.
