Description

The invention relates to a press-out sieve for wet mops, consisting of a sieve cup which has a perforated sieve cup bottom and a sieve cup wall which rises on all sides and at least partially slits, a sieve rim and push-on elements for plugging the press-out sieve onto an edge of a bucket, the sieve cup wall towards the inside of the sieve cup Cross-section is convexly curved and the screen cup wall rises outwards from the edge of the screen cup base at an angle of less than 20 ° with respect to the vertical

Round mops can be squeezed out easily in sieve baskets placed on buckets or in lever-operated presses; however, they do not allow precisely controlled movement on the floor, especially in corners, narrow spaces, on stairs and in other places that are difficult to access. Mops with an elongated floor plan are limited in terms of their movement options, especially on stairs; an increased effort is required for pressing out.

The frequently used, commonly referred to as "spaghetti mops" mops with relatively long threads hanging as a bundle can in practice only because of their length by spinning movements over the one to be cleaned Floor area. This means that large, free floor areas can be wiped quickly; handling is exhausting and unergonomic. In addition, the mop cannot be guided into narrow areas and corners, or only insufficiently. These mops can only be pressed in presses between press plates and are predominantly used only in the commercial sector.

Such press-out sieves are used for pressing out damp mops, which essentially consist of a bundle of strips, threads or rags made of absorbent material and have a mop head connected to a handle. The mop is pressed into the sieve cup from above, so that the water is squeezed out of the mop partly by the pressing action and partly by a wringing process due to knot formation. On the one hand, the screen cup wall rising from the bottom of the screen cup serves to exert a lateral pressure on the mop due to the shape of the screen cup tapering downwards; on the other hand, the sieve cup wall should hold the mop so that knot formation and thus wringing occurs when twisted. Known squeezing screens (DE 195 03 572 C1) have inwardly projecting ribs or depressions in order to hold the mop better during the rotary movement and to exert an increased squeezing pressure on the mop by the screen cup wall which increases in a straight line. These well-known sieve cups are therefore relatively narrow and deep; They therefore make it necessary to use a sufficiently deep water bucket so that the bottom of the sieve goblet is not yet immersed in the water and that a sufficiently large storage space is available for the water below the bottom of the sieve goblet.

Such tall buckets are heavy and at risk of tipping over. In addition to the press-out sieve suspended in the water bucket, a sufficiently large access area must also be available so that the mop can be immersed in the water. The minimum dimensions of the water bucket thereby predetermined make it difficult to securely hang in the relatively high and narrow press-out sieve for the reasons mentioned.

A known extrusion sieve of the type mentioned at the beginning (LU 88 754) has a rectangular plan with rounded corners.

The object of the invention is to design a press-out sieve of the type mentioned at the outset in such a way that, with a shallow sieve depth, a good press-out effect is achieved with wiping mops of different sizes, in particular also elongated mops.

This object is achieved in that the opening angle of the sieve cup increases up to at least 60 ° from the vertical to the edge of the sieve cup wall and that the outline of the sieve cup is oval at least in some areas.

The convex curvature of the sieve cup wall leads to the sieve cup having a smaller opening angle in its lower region adjacent to the sieve cup bottom, because the sieve cup wall rises relatively steeply here. At the top, In contrast, near the edge the sieve goblet is designed to be relatively flat with only slightly rising sieve goblet walls. This design has a good squeezing effect even with different sized mops. In particular, this also supports the knot formation for wringing out the mop, because the lower, hanging ends of the strips, threads or rags of the mop are effectively held in the slender, near-ground area of the sieve goblet and the convex inward-curved sieve goblet walls subsequently exert a high lateral squeezing force practice the mop.

Relatively large, in particular long, mops are nevertheless squeezed out well because their upper area, which is adjacent to the mop head, is pressed against the gently rising upper area of the sieve goblet walls by the pressure effect exerted from above and thereby squeezed out.

The design of the sieve goblet walls according to the invention makes it possible to make the sieve goblet flat and wide, so that the extrusion sieve has only a small depth overall and therefore does not require a particularly high water bucket.
Rather, even in a normal or even relatively low water bucket below the bottom of the sieve, there is still a sufficiently large receiving space for the water.

The plan of the sieve cup is oval at least in some areas.

The transition from the sieve cup to the sieve rim can lie on an approximately oval line. Additionally or instead, it can also be provided that the edge of the bottom of the sieve goblet is approximately oval.

This oval design of the sieve cup, at least in some areas, leads to a particularly good squeezing effect when the mop to be pressed out rotates.

It is particularly advantageous if the layout of the extrusion sieve is approximately an elongated, rounded rectangle and push-on elements are arranged on both narrow sides and on one long side, the sieve rim adjoining the sieve cup being interrupted on at least one of the two long sides. This squeeze screen can be attached in a particularly space-saving manner at the end of a water bucket that is rectangular in plan, with a sufficiently large access opening for immersing the mop remaining next to the squeeze screen. This bucket of water can therefore do a lot small and light, so that its handling is much easier in the household. Even elongated mops with a scrubber-like design and handling can be easily and efficiently squeezed out.

Further advantageous embodiments of the inventive concept are the subject of further dependent claims.

The invention is explained in more detail below using exemplary embodiments which are illustrated in the drawing.

It shows:

The extrusion screen 1 shown in FIGS. 1 and 2 is made as a one-piece part from plastic. It is intended to be placed on a cleaning bucket 2 (FIG. 3) in order to squeeze out a damp mop (FIGS. 4, 5 and 6).

The press-out sieve 1 has a perforated, essentially circular sieve cup base 3 in its central region, which is slightly curved upwards. A circumferential sieve gauze wall 5 rises upwards and outwards from the circular edge 4 of the sieve goblet base 3. The sieve cup base 3 and the sieve cup wall 5 form a sieve cup 6, which widens progressively from bottom to top. The perforated cup wall 5 provided with openings, such as slots 7 and possibly ribs 7a, is convexly curved in cross section (FIG. 2) towards the inside of the sieve cup 6.

In the preferred embodiment shown, the sieve cup wall 5 rises outwards from the edge 4 of the sieve cup bottom 3 at an angle of inclination a of less than approximately 20 ° with respect to the vertical S. The angle of inclination a increases up to the outer edge 8 of the sieve goblet wall 5 up to at least 60 ° with respect to the vertical. The sieve chalice wall 5 is thus more approximated to the vertical in its lower region near the ground, while it approximates more of the horizontal in its upper region near the edge.

A sieve rim 9 adjoins the edge 8 of the sieve chalice 6 thus formed, which rises more steeply from the edge 8 of the sieve chalice wall 5 than this edge 8.

In the embodiment shown in FIGS. 1-6, the edge 8 forming the transition from the sieve cup 6 to the sieve rim 9 lies on an approximately oval line. The outline of the squeeze cup 1 is approximately an elongated, rounded rectangle. Push-on elements 10 with push-on slots 11 which are open at the bottom and fit on the edge of the bucket 2 are on the two narrow sides and on one Arranged on the long side of the rounded rectangle thus formed. As can be seen from FIG. 1, the sieve rim 9 adjoining the sieve goblet 6 is interrupted on at least one of the two long sides, in the exemplary embodiment shown even on both long sides.

The depth of the strainer 6 is less than or approximately equal to half the width of the strainer 6. This flat, wide shape of the strainer makes it possible to use a bucket 2 with only a relatively small depth, which is therefore particularly stable. As a result of the narrow outline shape of the press-out screen 1, in addition to the press-out screen 1 in the bucket 2 there remains a sufficiently large access opening 12 through which a damp mop can be immersed in the bucket 2.

4, 5 and 6 show the pressing out of three differently large and wide mops 13, 13 'and 13 ", which are each connected to a mop handle 15 by means of a mop holder 14.

The mop 13, 13 'or 13''is pressed from above into the filter cup 6 and rotated in the process. The respective lower section formed by the ends of hanging strips, threads or rags of the mop 13, 13 'or 13 "is clamped and held between the regions of the screen cup wall 5 near the bottom due to the small pitch angle a (FIG. 2), so that the mop can be rotated to form a knot and wrung out at the same time.

In particular, large and wide mops, such as the mop 13 ″ shown in FIG. 6, finally come to rest in the only flatly rising upper regions of the screen gauze wall 5 and are essentially squeezed out there by the vertical pressure exerted. In the upper area near the edge there is sufficient space for elongated and / or larger mop heads.

Fig. 7 shows in a plan view corresponding to FIG. 1, a modified embodiment of the extrusion screen 1, which differs from the previously described embodiment essentially only in that the edge 4 'of the cup base 3' is approximately oval. Its main axis (axis of greatest longitudinal extent) is at right angles to the main axis (axis of greatest longitudinal extent) of the likewise oval edge 8 of the sieve cup 6. This results in an additional squeezing effect when the mop to be introduced is rotated.
