Description

Technical field

The invention relates to a holder for fastening a Mops at the end of a stem, being a number relatively flexible, absorbent strip from one Textile material preferably at an angle to each other essentially transverse to the longitudinal axis of the stem by clamping between a headboard and a plate is set. The holder points in the area of Attach the strips to a base, the one has greater length than width. Such mops are used for wet cleaning of floors.

State of the art

From DE 19833553 C1 a mob is attached to the Known end of a broomstick that includes a bracket where a number of relatively mobile, absorbent Strips of a textile material essentially is set transversely to the axis of the stem. The Stripes are anchored in the bracket using a mushroom head the mushroom head is in its outer dimensions smaller than the holder. The holder and the mushroom head are domed.

From US 5, 199, 130 a mop is known, the Holder is flared, with the inserted Strip the mop over one with a central thread provided round plate can be clamped. The In contrast to the conical holder, the plate is flat educated.

From ES-U-1 043 526 a mop is known, the Holder has a tapered corner, the Holder based on a round elliptical basic shape in the area of the corners over a not insignificant Part of its longitudinal extension is a straight line Area towards the corner. The holder himself can be dome-shaped. The stripes lie here all essentially in the same direction without Angular offset to each other.

The invention has for its object a Develop mop so that its manageability and especially the suitability for cleaning corners is improved.

Presentation of the invention

According to the invention this is achieved in that the Holder one co-operating with the strips of the mop Boundary margin that in at least two are in the direction of the longitudinal axis of the holder extending edge areas is divided that the Edge areas without changing the direction of curvature with one constant or at least in sections changing radius of curvature are curved that the Ratio of length to width at least 1.2 and is at most 4, preferably more than 1.6, and that the radius of curvature of the edge areas at least is 0.61 times and at most 4.25 times the width.

By forming two curved edge areas is a work independent of the current one Position of the mop reached because of Mop always lies with the curved edge area. Due to the curvature, the mop can move a certain amount Angle of rotation are rotated, with the mop on the Holder or the strip attached to it rolls off. This rolling motion is increasing Angle of rotation difficult because of the focus of the mop is raised. Experiments have shown that the ratio of length to width at least 1.2 and at most 4, preferably more than 1.6 to improve the handling of the mop.

A limitation of the rotation represents the advantageous Training provided corner, to whose Overcoming a significantly higher effort required is. Because of the opposite of a circular holder existing restoring effect of the holder in a In the middle position, the holder can be used to make a special one simple and effortless work in S-movements accomplish.

The fact that the boundary edge at the length limiting Ends avoiding acute-angled Corners can each have a flattening, is a Overturning the mop from an edge area to the other difficult.

Furthermore, the boundary can be outside the Length-limiting ends have corners to make them special Get geometries and rolling movements.

The edge regions advantageously consist of each at least one segment of a circle. Instead of Sections of a circle can also have other curves, if the holder is easy to turn the positional stability is to be changed.

In the event that the two circular sections are mirror-symmetrical handling is independent of that Use of the respective border.

Different suitability for rotatability should be provided can be the curvature of the first edge region larger than the curvature of the second edge area to get voted.

Finally, it is an advantage if the by the the two ends that limit the length to the boundary line created tangents included angles is a maximum of 90 degrees, since this also means cleaning the corners usually found in buildings can.

The head section can be used to increase the radius of curvature be pulled down at its corners so that overall results in a spatial curvature of the edge areas.

To further improve the rotatability of the mop can connect the holder to the handle via a Tilting joint movable in the longitudinal direction of the holder.

Means are advantageously on the joint Limitation of the tilt angle of +/- 60 ° based on the provided perpendicular to the longitudinal axis of the holder. All A limitation of the tilt angle is particularly advantageous to +/- 25 °, since the easy squeezing is also possible here in a sieve without significant evasion of the Holder is made possible.

According to a further development, the base area of the Plate larger than that of the headboard, making the Plate protrudes circumferentially over the head part. This has the advantage that the effective wiping width increases without the material content of the wiping material, especially the stripe. About that In addition, the force is transferred to the strips of the mop over a hard edge, so that next to the Wiping is also possible to a certain extent is.

To improve rigidity, the headboard can be hood-shaped be formed, in particular concave. there can at the transition of the hood-shaped over the edge area trained sections formed an edge his.

The corners are advantageously with a radius between between 0.05 times and 0.25 times that Width of the holder rounded so that a rolling movement is made possible via the corners, albeit for this an increased compared to the rolling movement on the outer edge Force is required.

In the event that the corners are rounded, too a ratio of length to width of at most 2.4 and the ratio of the radius of curvature (R) to the width (B) of at most 3.38, where in particular a ratio of length to width of about 1.8 has been found to be advantageous. It can be advantageous if the length of the holder compared to one in the area of the length limiting The ends of the corners have a length between 0.99 times and 0.6 times, preferably between 0.95 times and that is 0.85-, since there is still in this area a sufficient improvement in wiping performance and the manageability is achieved without the actual Corners are formed that may not be at proper handling can cause damage.

Embodiments

In Fig. 1 is a holder for attaching a mop shown at the end of a stem. The holder includes a head part 1, on which a cylindrical connector 2 for locking with a not shown Counterpart of a handle connected in one piece is. The head part 1 consists of 2 curved half-shells 3, 4, the formation of an edge 5 abut each other and are also materially connected.

The head part 1 has an elongated shape, i.e. the length and the width are noticeably different. About that in addition, corners 6, 7 are formed on the head part 1, these corners 6, 7 each on the longitudinal direction trained end of the head part 1. Between the two shells 6, 7, the half-shell 3, 4 is formed so that without changing the direction of curvature a radius of curvature greater than half the width is the head part 1, formed. The corners 6, 7 are rounded off itself.

2 shows the geometric relationships of the headboard even more clearly with regard to the base area. First of all, the head part 1 is arranged with the one in the middle Recognize coupling piece 2. To this Coupling piece 2 extends around the half shells 3 and 4, forming edge 5 to an outer Contour 8, 9 and the corners 6, 7. The arcuate Contour 8, 9 runs from corner 6 to corner 7 such a curvature that the longitudinal extent from corner 6 to corner 7 perceptibly larger than the width is b. The outer contours 8, 9 can be at least partially designed as a circular arc, whose radius of curvature is significantly larger than the distance to the central axis of the head part going through the corners 6, 7 1 is.

In the present case, the ratio is length to width about 1.8, with the fact that with increasing Ratio the corners 6, 7 are always sharper and one increasingly slimmer head part 1 is created. With decreasing Ratio approaches the footprint of the headboard a circle. According to the invention, however, should a base area deviating from the circle.

The course of the curvature is shown in FIGS. 3 and 4 the half-shells 3.4, as well as the formation of the Edge 5 and corners 6, 7 and the position of the outer contours 8, 9. Thanks to the dome-shaped upward to the Coupling piece 2 half shells 3, 4th can a power transmission to the Corners 6, 7 take place without any significant Deformation of the holder occurs. That through this shape stiffness produced is compared to a simple one Significantly improved plate.

5 is another embodiment of a Head part 10 according to the invention shown, in which the Connection of the head part with a not shown Style is done via a tilt joint. The headboard points to this 10 an eye 11 with a through opening 12. The eye 11 is in the longitudinal direction, thus parallel to the imaginary connection of corners 6 and 7 on the top the half-shells 3, 4 and the opening 12, which defines the tilt axis 13 extends in the direction the width of the head part 10.

It goes without saying that having a style with engaging in the opening 12, perpendicular to the style axis continuing a tilt of the style around the Tilt axis 13 is possible. This means the corners 6, 7 of the head part 10 moved to the style or away from the style can be. Further degrees of freedom of movement of the Headboard 10 opposite the style are not provided.

By the distance between the tilt axis 13 and the outer contour 8 as little as possible as a support edge on the textile material to hold, the convex half-shells 3,4 a concave depression 14 in which the eye 11 is housed. In addition there are intake openings 15, 16 provided between the eye and the each corner 6, 7 are arranged and serve to to attach a plate to the head part 10. In the Fig. Through Fig. 8 is the complete holder except the strip of textile material is shown. 6a shows the schematic arrangement of the head part 10 with a plate 20, the connection via the receiving opening 15 and one protruding from the plate 20 Pin 21 takes place through the head part 10 protrudes and fixed in the receiving opening 15 is. In the space 22 between the head part 10 and Plate 20 are the strips of the mop that thus between the outer contour 9 as the lower edge of the Head part 10 and the top of the plate 20 clamped are. The head part 10 is about the tilt axis 13 tiltable with respect to the style, not shown.

It can also be seen that the plate 20 in their outer dimensions beyond the head part 10 there is an overhang on the edge is. 6b is a concrete embodiment shown with all appearing edges, here a style-facing coupling piece 24 in a tilted Position is shown. In addition, the Stiffeners 25 that are dome-shaped between the plate 20 arching head part 10 are arranged, at least partially shown.

In Fig. 7a the structure of the holder is omitted the stripe is particularly clear because of the proportions of the head part 10 and the plate 20 become clear. So it can be clearly seen that the plate 20 over the outer boundary 8 of the head part 10 protrudes and a protrusion along the entire outer contour 8, 9 23 has. The plate 20 is designed so that for the head part shown in Figs. 1 to 4 described geometry is realized, that is the length is greater than the width and the elongated Ends corners 26, 27 are formed which in turn can be rounded. In particular, the in Fig. 2 angular relationships in the range of Corners 6, 7 or for the plate 20, the corners 26, 27 realized.

In the corner 6 straight lines G1, G2 are drawn in through the outer point of corner 6 and the longitudinal axis of the headboard 1 go. The straight lines G1, G2 close one An angle α, which is in the range of 90 °, in Embodiment slightly above. Already this constructive design allows a significant improvement the ability to clean corners, especially However, it is advantageous if the straight line G1, G2 with an angle of 90 ° completely outside the head part 1 lie. Mathematically one speaks here of the Envelopes.

The arrangement also results from FIG. 7a of the eye 11 and the tilt axis 13 and the location of the Receiving openings 15, 16 for the fasteners of the Plate 20.

In Fig. 7b is a construction drawing with inserted Strips 28, 29 shown of a textile material, which is the width of the width of the head part 10 correspond and a smaller width than the plate 20th exhibit. By arranging each other at an angle offset strip 28, 29, however, becomes the entire Plate 20 completely covered by the strips. A such arrangement of the strips is from the prior art Technology already known.

8a is a longitudinal section through the holder with a plate 20 protruding above the head part 10 shown, an eye 11 to form a tilt joint is available. In the gap 22, the strips of the mop.

In Fig. 8b is a construction drawing with a tilted coupling piece 24 shown, which on the Eye 11 is attached and with a not shown Style can be connected. The tilt angle shown Beta is about 60 degrees from the vertical. However, the tilt angle can be used for better handling limited to +/- 25 degrees. Are in the gap 22 several layers of strips 25 partially shown, the plate 20 with the connecting means 21 with the head part 10 is connected.

It is important to note that when using a plate with larger dimensions than the headboard the actual shape of the headboard to achieve the Advantages according to the invention only of limited importance is as long as the stripes between the plate and the headboard be noted that the wiping forces over the Plate to be transferred to the strips. Nevertheless is based on the outer shape of the headboard the shape of the plate makes sense to appropriate attachment the stripe and a compulsory alignment to effect the streak.

To generate an increased holding force of the plate 20 on the headboard, the plate 20 can not be installed Condition arched to the side of the mop's stripes be so that in this state the outer limits and the corners 26, 27 rest, the one in between However, the area is hollow. About a slide the strip inserted between the headboard and plate 20 should be prevented on the side facing the strip Formed several projections 30 with tips 31, which in the textile material of the strips during assembly of the holder are pressed in.

According to FIG. 10, these projections can be in the middle region the plate 20 as well as in the area of the corners 26, 27 arranged.

From the geometry shown in FIG. 10 it can be seen that that the outer edge of the plate at every point has a curvature, the radius of curvature outside the corners 26, 27 significantly larger than half Width of the plate is 20. In particular, the external boundary through a circular section with constant Radius of curvature can be formed, but the outer contour can also different from several sections Curvatures can be composed, for example by 4 Sections of a circle which are marked in the longitudinal direction by "pointed" Corners 26, 27 and in the width direction by as transition regions 31, 32 formed with blunt corners are. It is essential that the radius of curvature these long sides opposite a circular base is much larger with the same width. This has the consequence that the holder either with the head part 1 or with the plate protruding over the head part 20 and the strip of the mop standing beyond it rolled off a bit on the surface to be wiped can be until the rolling motion at the corners arrives and another roll a resistance opposed.

Through this rolling, that alone without a mechanical joint possible due to the shape according to the invention is the manageability of the mop with the S-shaped Wiping significantly improved. The one for unrolling responsible radius of curvature can be increased that the corners 26, 27 and 6, 7th pulled further down, creating the outer edge of the head part or the plate three-dimensionally is curved. Here, a value of one Tenths of the longitudinal extent must not be exceeded.

This can improve the ability of the mop to unroll that a tilt joint is provided which allows a maximum tilt angle of +/- 60 degrees. Experiments have shown that in particular a Tilt angle of +/- 25 degrees due to the limited Angular position further improves manageability, especially when wringing out into a sieve. About that addition, it is through the use of the tilt joint possible to insert the mop specifically in corners and to the corner so that a cleaning in the Corners is possible.

11 and 12 are the basic geometric Reproduced ratios, the sizes L, B, B / 2, R and Lc can be represented by the formulas for a segment of a circle calculate if some values are specified. So results for a plate with a length L = 100 and one Width B = 54 a ratio L / B of 1.85 for which Radius of curvature results in the case of a segment of a circle a value of about 60 and a ratio to Width of about 1.1.

For a plate with an L / B ratio of 1.2 for the radius of curvature R in the case of a Circular section has a ratio to the width of about 0.61.

For a plate with an L / B ratio of 4 results for the radius of curvature R in the case of a Circular section has a ratio to the width of about 4.25.

Finally, in Fig. 12 there is a geometry with flats 34,35 shown at the ends, making opposite 11 with the corners 26 and 27 and the length L in FIG there is a reduced length Lc.

The typical radius of curvature for the corners 26, 27 is in the range of 1 to 10 mm.
