* Device for squeezing wet cloths

?■ The invention relates to a device with which primarily

\ a daily, repetitive, annoying task becomes superfluous, namely the strenuous wringing of wet &igr;

&igr; Cleaning cloths. It is replaced by effortless squeezing.

The devices available on the market are cumbersome and do not provide satisfactory drying results. In addition to complex roller constructions through which wet cloths are pulled or rolled, lever presses are also known, but these require a great deal of force to operate. They also tip over easily.

The device according to the invention is based on the following tasks:

- Achieve an excellent drying result with only minimal effort,

- vertical or slightly diagonally downward force introduction, which is more favourable in terms of work technology and statics, with

- a short stroke of the device and

- convenient and safe operation.

The solution to these tasks is explained in more detail using an example in conjunction with 1 sheet of drawings.

The base frame 12 has an upper end region of an orbit S in which the free ends of a bracket 3 are rotatably mounted. The opposite, closed part of the U-bracket 3 is firmly connected to a plate 1, which is of sieve-like design, as well as a plate 14 attached at right angles to its underside 4.

In a rotation axis 6, which is arranged in a central area of the base frame 12, the free ends of a bracket 4 are rotatably mounted, at the opposite

Tsil , dsr QSSCnluäsönsri side of u-Süyölä 4, a plate

is attached, the longitudinal and transverse axes of which run parallel to the rotation axis 6. The distance from the rotation axis 6 to the plate 2 is shorter than the distance from the rotation axis to the plate 1.

Next to each of the shorter edges of the plate 2, a roller bearing 7 is arranged on the bracket 4, the axis of rotation of which runs parallel to the axis of rotation 6 and the outer surface of which is supported on a surface 13 on the bracket 3. The channel base 14 runs parallel to the support surface. The plate 2 is shorter than the clear distance between the bracket arm 4 (Fig. 2) and does not reach the base plate 14, so that a slot 15 is created all around. In a central area of the base frame 12 and the bracket 3, the ends of at least one spring 16 are supported, the preload force of which is greater than the proportional weight of the device.

When an operating force P' is applied to the structure, which together with the weight of the device and the contents of the trough is greater than the opposing forces from the pre-tensioning force of the spring 16 and the friction losses, the bracket 3 rotates the sieve 1 connected to it with the trough base 14 around the common axis of rotation 5 in the direction of the base frame 12 along sections of the lateral surface of imaginary cylinders whose central axes are identical to the axis of rotation 5. In this case, the bracket 4 is set in motion around the axis of rotation 8 via the roller bearing 7 on the bracket 3.

Due to the distance between the rotation axes 5 and 6 and the different distances of the plates 1 and 2 to the corresponding rotation axes 5 and 6, the plate 2 is pressed towards the plate 1 and the distance between the two plates is reduced until the working section is reached.

Fig. 3 and Fig. 4 show a longitudinal section A'-B' and a view EF of the device according to the invention in a working position.

As a result of the introduction of the operating force P, the distance between plates 1 and 2 has become significantly smaller.

In addition to the spring preload 16, the increasingly compressed contents of the channel 8 counteract this downward movement. The water is pressed out of the wet cloth and can flow unhindered into the container 11 through openings in the sieve-like plates 1, 2 and 14. The pressure forces on the plate 2 that arise during this process form a force pair, taking into account the force deflections in the rollers 7 and friction losses with the tensile force in the frame 3 in the area of the support surface 13, which counteracts the downward movement of the device as a result of P. Since the distance between this force pair is very small (approximately 1/8 of the force pair P around the axis of rotation 6), the compression pressure in this example is approximately 8 times as large as the operating force P or P'. These force deflections are absorbed within the device and dissipated without any external effect.

Fig. 5 shows a top view of the device (upper half: basic position, lower half: working position).

The device according to the invention covers less than the Half of the floor area of container 11.

The scrubber and cleaning cloth can be dipped into the cleaning water through the area 17 that is open at the top. The cleaning cloth is then placed in the wide press trough 3 and the operator P is guided in by means of the scrubber. After the cloth has been dried by the press pressure as described, it is still hanging on the scrubber and is available again for mopping up the sod* without you having to bend down or struggle with wringing it out.

In order to prevent accidents, suitable devices must be used to ensure that the channel 14 cannot close completely (finger crushing).

The invention is not limited to the embodiment described. The possible compression pressures can be increased or reduced by making minor design changes.

The support 12 can be attached to a building wall or a support, etc. Furthermore, it can be advantageous to arrange the rotation axes 5 and 6 in parts molded directly onto the container.

The bracket 3 can also be arranged on the underside of the gutter floor so that the gutter remains completely open at the top and can therefore be used more freely.

Likewise, lifting to the basic position can be achieved by a bow or tension spring.

Furthermore, the drive can be electrical, especially in stationary systems.

It may also be useful to add a handle to further increase the leverage.

It may also be useful to close the ends of the gutter with end plates so that no water can flow over the edge of the container.

Furthermore, the device is also suitable for drying wet laundry, wet chamois leather, wet paper, for squeezing fruit, raw mashed potatoes or for holding, pressing and gluing workpieces.
