WAYS FOR CARRYING OUT THE INVENTION

FIG. 1 is a sectional view of a hand roller device 100 having a rotatable roller device 20 with an elastic cylindrical sponge body 60, the sponge body 60 being compressible.

The mode of operation of the compression is described below in principle.

The hand-roller device 100 has a rectilinear handle profile region 12, an adjoining transition profile region 14 which initially runs obliquely downwards and then curved by approximately 180 ° (degrees), and a straight-line axis profile region 16 adjoining the transition profile region 14. The profile areas 12, 14, 16 are formed by a one-piece curved round tube profile. The axle profile region 16 is present substantially perpendicular to the handle profile region 12. In the transition region between the transition profile region 14 and the axle profile region 16, a first pivot bearing unit 24 is non-rotatably provided on the axle profile region 16, on which a first rotor unit 22 is rotatably mounted. The first rotor unit 22 has a protruding circumferential flange 30, which abuts the end face of the sponge body 60. Furthermore, fixing pins 31 are formed on the flange 30 in the direction of the sponge body 60, which fix the sponge body to the first rotor unit 22. On the fixing mandrels can also be dispensed with.

At the opposite outer end of the axle profile portion 16, a second rotary bearing unit 28 is rotatably provided, which is longitudinally displaceable in the axial direction and on which a second rotor unit 26 is rotatably mounted with a peripheral flange 30. As a result of this embodiment, a rotatability of the roller device 20 about the axis profile region 16 is ensured permanently reliably.

The compressibility of the sponge body 60, which is preferably designed as a viscose sponge, is ensured by the following components. At the handle profile area 12 is longitudinally displaceable a displacement unit 96.1 available, which is designed as a handle 76. The handle 76 can be moved down to a stop unit 78 down. Within the handle profile region 12, the transition profile region 14 and the axle profile region 16, a flexible tension element 70 is arranged, which is designed as a Bowden cable 70. One end of the cable of the Bowden cable 70 is anchored to the handle 76. The one end of the sheath of the Bowden cable 70 abuts against the stop unit 78. The other end of the cable of the Bowden cable 70 is anchored to the second pivot bearing unit 28. The other end of the sheath of the Bowden cable 70 is connected to the first pivot bearing unit 24. Between the first rotor unit 22 and the second rotor unit 26, a first elastic unit 56 is arranged, which is designed as a helical spring. On the first pivot bearing unit can also be dispensed with. In this case, the first rotor unit is rotatably mounted directly on the axle profile area.

Now, if the handle 76 is pulled in the direction of arrow Z1 along the handle profile area 12 upwards, this shift is transmitted via the Bowden cable 70 to the second pivot bearing unit 28 and thus also to the second rotor unit 26 so that they move in the direction of arrow Z2 and against the action of first elastic unit 56 and the elasticity of the sponge body 60 squeeze this, so that previously taken liquid in the sponge body 60 is pressed out of this.

If, after compressing the sponge body 60, the handle 76 is released, the sponge body 60 expands due to its elastic material property and with the assistance of the elastic unit 56, so that the handle 76 is displaced down to the abutment against the stop unit 78. In this state, the sponge body 60 is completely relaxed and can be used for further fluid intake or other cleaning purposes.

FIG. 3 shows a first constructive variant of a hand roller device 10.1 which implements the above principle. The same components bear the same reference numerals and will not be explained again.

The first and second rotor unit 22, 26 are cup-shaped with protruding flange 30, wherein within the pot, the first and second pivot bearing unit 24, 28 is arranged. The pivot bearing units 24, 28 are formed as hub units. The second pivot bearing unit 28 has an inwardly directed guide projection unit 62 which engages in a slot 64 present in the axle profile area 16 and which at the same time serves to anchor the cable of the Bowden cable 70. Thus, the second pivot bearing unit 28 forms the pivot bearing for the second rotor unit and on the one hand rotatably and on the other hand longitudinally displaceable on the axle profile portion 16 is present.

Supporting may be between the first pivot bearing unit 24 and the second pivot bearing unit 28, a second elastic unit 58, which is preferably designed as a helical spring present.

The displacement unit 96.1 is designed as a sleeve unit around the web profile region 12 and has an inwardly directed projection unit 102 to which the one cable end of the Bowden cable 70 is anchored. The projection unit 102 is guided within a slot 104 present on the web profile region 12.

In an embodiment variant shown diagrammatically in FIG. 4, the slot 104 has transverse recesses 106 arranged in a grid-like manner into which the projection unit 102 can be brought into positive engagement so that the displacement unit 96.1 can be locked in almost any position on the handle profile region 12.

To reduce the expenditure of force for expressing the sponge body 60, a third elastic unit 66, which is preferably designed as a helical spring, is present according to a preferred embodiment between the displacement unit 16.1 and the upper end region of the stem profile region 12, which abuts the displacement unit 26.1 in the abutment unit 78 Condition under tensile stress sets.

In Figure 3, the elastic sponge body 60 is shown in a longitudinal section and a side view. The cylindrical peripheral contour is superimposed on a wave contour 108. The sponge body 60 further has a continuous cylindrical inner recess 61. In this inner recess 61 of the axle profile portion 16 is arranged with the first elastic unit 56.

The hand roller device 10.1 further has a blocking unit by means of which the rotational movement of the roller device 20 can be optionally locked or unlocked. The blocking unit has a pivoting lever 36 which is designed as a U-bracket and whose web end areas are arranged so as to be rotatable about a rotation axis 37 perpendicular to the axis direction of the axle profile area 16. The pivoting lever 36 is pivotable from a locking position to an unlocking position about the axis of rotation 37, wherein the unlocking position shown in dashed lines in Figure 2 is. On the swivel bracket 36 is an inclined to the longitudinal axis of the swivel bracket 36 arranged Kragelement 39 is present, at the free end of a projection unit 32 is formed. At the same time, the first rotor unit 22 has four circumferentially offset by 90 ° (old) offset through recesses 34 in its flange 30, in which the projection unit 32 is positively engageable depending on the positioning in engagement. For blocking the roller device 20, the pivot lever 36 is pivoted from the unlocking position (dashed line) into the locking position (solid representation). If the projection unit 32 does not hit on a recess 34, it initially bears against the outer surface of the flange 30 in an elastically pressing manner due to the inclined arrangement of the cantilever element. By slight rotation of the roller device 20, the projection unit 32 can be brought into coincidence with a recess 34, so that the projection unit 32 then engages in the recess 34 and the locked state is given because then the first rotor unit 22 can not rotate.

The fixation of the pivot lever 36 in the unlocking or locking position (detail C in FIG. 2) is shown in greater detail in FIGS. 22 and 23, respectively. The bow-shaped pivot lever 36 engages around the transition profile region 14. On the transition profile region 14, a clamping spring unit 35 is connected on the outside, one end 47 of which engages under the outer wall of the transition profile region 14 and the other end 48 is fastened to the transition profile region 14 on the outside by means of a screw 49. Between the outer wall of the transition profile region 14 and the inner wall of the clamping spring unit 35, a web of the pivot lever 36 is arranged. In the unlocking position 67 and in the locking position 68, the distance between Clamping spring unit 35 and transition profile region 14 selected slightly larger than the diameter of the one bracket of the pivot lever 36. Between two positions 67, 68, the distance is chosen smaller, so that the pivot lever can be pivoted only by applying a force from one to the other position (arrow S), that is, a reliable locking of the respective desired position is ensured.

The illustrated in Figure 5 third embodiment of a hand roller device 10.3 works to compress the roller body 20 on the same principle as the devices described above, but the blocking effect is generated in a different manner and the displacement unit 96 is formed differently.

The blocking effect is generated in that the first rotor unit 22.1, 26.1 is brought into positive engagement with the first and / or second pivot bearing unit 24.1, 28.1. FIG. 10 shows the first rotor unit 22.1. Instead of the mandrels, the rotor unit 22.1 inwardly facing, circumferentially distributed by 90 ° (old degree) on the flange 30 integrally formed wall elements 63 which engage corresponding recesses present in the sponge body 60. In the bottom of the pot rotor unit 22.1 circumferentially grid-shaped projection units 41 are integrally formed.

In the pot region of the first rotor unit 22.1, the first pivot bearing unit 24.1 is arranged, which is shown in Figure 9. It has on the latching projections 41 facing side corresponding recesses 43, in which the locking projections 41 are brought by a relative displacement of both components positively engaged can, as soon as the rotational position of both components match accordingly. The second rotor unit 26.1 or the second pivot bearing unit 28.1 is designed accordingly. In contrast to the first pivot bearing unit 24.1, the second pivot bearing unit 28.1 is mounted longitudinally displaceably on the axle profile area 16. Also, these pivot bearing units have an inwardly facing integrally formed projection unit 62 which engages in the slot 64 of the axle profile portion 16 and on which in the case of the second pivot bearing unit 28.1 the rope of the Bowden cable 70 is anchored.

If the sponge body 60 is in a relaxed state, the latching projections 41 of the rotor units 22.1 and 26.1 are disengaged from the latching recesses 43 of the first rotary bearing unit 24.1 or 28.1, ie a rotation of the roller device 20 is possible.

If the blocking action is to be generated, the displacement unit 96 is displaced upward by the amount B (see FIG. 5), this displacement movement being transmitted via the Bowden cable 70 to the second longitudinally displaceable pivot bearing unit 28.1. This initially leads to a relative displacement between the second pivot bearing unit 28.1 and the second rotor unit 26.1, so that the latching projections 41 of the second rotor unit 26.1 optionally interlock positively with slight simultaneous rotation of the roller device 20 in the latching recesses 43 of the second pivot bearing unit 28.1. In this state, the rotationally fixed second pivot bearing unit 28.1 is positively coupled to the second rotor unit 26.1, that is, a rotation of the roller device 20 is no longer possible.

In the interior region, an elastic spring element 45, which is embodied as a circumferentially existing helical spring, is present on the outside in the transition profile region 14, which is supported on the transition profile region 14 via a projection unit 53 and via a displaceable disk 46 on the front region of the first rotor unit 22.1. When the displacement unit 96 is displaced upwards by the amount V (FIG. 5), the latching projections 41 and the latching recesses 43 of the first rotor unit 22. 1 or of the first rotary bearing unit 24. 1 also engage. By means of the spring element 45, it is possible to set the required force for moving the displacement unit 96. This is done in a simple manner by turning the coil spring 45. The spring element 45 causes when unlocking the first rotor unit 22.1 with the pivot bearing unit 24.1 disengaged, since their spring force is greater than the spring force of the runners between the units 22.1, 26.1 arranged first elastic unit 56.

It is also possible that the blocking takes place only on one end face of the roller device. Thus, for example, the first pivot bearing unit may be formed as a normal fixed unit on which the first rotor unit is rotatably arranged. The spring element 45 can then be completely eliminated.

In the handle profile portion 12, a Vorschalthülse 55 is connected below the displacement unit 96, which serves as a lower stop for the displacement unit 96 and within which the Bowden cable 70 is led out of the interior of the web profile region 12 and the cable of the Bowden cable 70 is further led up to the Anchoring position on the displacement unit 96.

The displacement unit 96 is shown in more detail in Figures 11 a, b, c. It is partially formed as a spreader. In its lower end region, the displacement unit 96 has an embossed circumferential groove 110, in which two elastically expandable retaining rings or clamping rings 116 (see FIGS. 10 a, b, c) are arranged, which ensure that the displacement unit 96 reliably engages the handle profile region 12 locked in place.

The displacement unit 96 has four circumferentially radially offset by 90 ° (old degree), downwardly open slots 112. The underside anchoring position of the cable of the Bowden cable 70 to the displacement unit 96 is indicated in Figure 11 b) by the reference numeral 114. In order to allow the displacement of the displacement unit 96, which is simultaneously designed as a handle, along the handle profile region 12, the expansion lever 98 shown in more detail in FIG. 14a to d is used. The expansion lever 98 has an outwardly inclined grip region 99 and a lower side integrally formed, the handle profile portion 12 semicircular comprehensive form portion 101. In its end region, the molding region 101 has right-angled inwardly extending edge portions 103, wherein these two mutually opposite edge portions 103 engage in the opposite slots 112 of the displacement unit 96. If the grip area 99 is then pressed in the direction of the arrow X (see FIG. 9), this leads to a widening in the region of the clamping rings 116 due to the lever effect, so that the displacement unit can be displaced overall in the longitudinal direction on the handle profile area 12, for example in the direction of the arrow Z (FIG. 5). for squeezing the sponge body. Once the expansion lever 98 is released, the clamping rings 116 again ensure that the displacement unit is securely locked in this instantaneous position on the handle profile portion 12.

FIG. 13 shows a fourth exemplary embodiment of a hand roller device 10.4, in which the handle profile region 12 is designed to be telescopic, wherein the locking of the telescopic tubes takes place via an eccentric lever unit 118. In Teleskopierbereich two more handles 120 are available. In contrast to the above-described hand roller devices, here the axle profile area 16.1 itself is telescopic, that is to say it is not necessary for the sponge body 60 to compress a second rotary bearing unit 122, which must be longitudinally displaceable on the axle profile area 16.1. At the "stationary" second pivot bearing unit 122, the cable end of a Bowden cable 70 is also anchored, which is in operative connection with the other end with the displacement device 96. On the second pivot bearing unit 122, a second rotor unit 124 is rotatably mounted with a peripheral flange 126.

On the free end of the roller device 20 opposite end face a first rotor unit 128 is rotatably mounted on the telescoping axle profile portion 16.1. The first rotor unit 128 also has a flange 130 with through recesses 132, wherein for blocking purposes in one of these recesses 132 an existing bolt 32 can be introduced, which is in operative connection with another Bowden cable 40, wherein the other end of the Bowden cable to a further displacement unit 46 is connected, which is arranged displaceably in the longitudinal direction on the Vorschalthülse 55. In order to block the roller device 20, the further displacement unit 46 must therefore be displaced downwards in the direction of arrow U in the case of the hand roller device 10.4 according to FIG. 15, whereby the bolt 32 is extended by means of the Bowden cable 40 and snaps into one of the recesses 132.

FIG. 14 shows a fifth embodiment variant of a hand roller device 10.5, which in principle has the same structure as the hand roller device 10.4 according to FIG. 13. Therefore, the same components bear the same reference number and will not be explained again. The main difference is that not the displacement unit 96 or the further displacement unit 46 is used to generate the movement of the Bowden cable, but an aggregate 144, in particular an electric motor which can be controlled via corresponding switching units 140 and 142, to unlock the roller device 20 or to lock or compress the sponge body 60.

The sixth variant of a hand roller device 10.6 shown in FIG. 15 is similar in construction to the hand roller device 10.4 according to FIG. 13 and also has a telescopable axle profile region 16. Both rotor units 124, 128 are mounted directly rotatable on the axle profile area 16.1. However, in this embodiment, the handle profile portion 12 is kept relatively short and the compression of the sponge body 60 via a present in the upper end region of the handle profile portion unit 146, which acts on the Bowden cable 70 on the second rotor unit 124. The blocking also takes place via the acted upon by the Bowden cable 40 bolts 32, wherein the other end of the Bowden cable 40 connected displacement unit 46 is structurally slightly different, namely as a slide switch. Instead of the unit 146 may also be a connected to the Bowden pull ring 65 may be present (dashed line in Figure 15), which is operated manually.

FIG. 16 a shows schematically the compression of the sponge body 60 by linear displacement of the second rotor unit 26 and the second rotary bearing unit 28 for emptying the liquid into a container 150, which has a screen or grid 152 on the upper side. According to FIG. 16b, it is also possible to design the first rotor unit 22 or the first rotary bearing unit 24 to be longitudinally displaceable, so that manual compression of the sponge body 60 is also possible as a result.

FIG. 17 shows schematically how fluid can be taken out of a first container 154 by means of the described hand roller device 10.1 and transferred to a second container 156. Thus, first the hand roller device 10.1 is inserted with compressed sponge body 60 in the first container 154 below the liquid level and then the sponge body 60 is relaxed (arrow S). As a result, he takes up liquid. In this state, the hand roller device 10.1 is placed in the second container 156 and then the sponge body 60 is compressed by moving the displacement unit 96 (arrow D), so that the sucked liquid exits into the second container 156.

FIGS. 18 and 19 show a further embodiment of a hand roller device 90, whose mode of operation substantially corresponds to the mode of operation of the hand roller device 10.4 according to FIG. 13 with a telescoping axle profile region 16.1, whereby, however, a transition profile region 14.1 is used which is designed as a housing profile and replaces the Bowden cable has been through a simple Zugseileinheit 80, within the housing profile 14.1 via pulleys 160, 161, 162 of the second rotary bearing unit 122 is supplied. The blocking effect is likewise made possible by means of a bolt 32, which is mounted so as to be longitudinally displaceable on the housing profile 14.1 and can be engaged in a recess 132 of the first rotor unit 128, the bolt 32 acting on a spring lever 164 which is accessible from outside the housing profile 14.1 and which acts in an unlocking manner. or locking position on the housing profile 14.1 can be locked.

The housing profile 14.1 is connected in a liquid-tight manner to the telescopic axle profile area 16.1.

Finally, FIG. 20 shows a further embodiment of a hand roller device 100 in the lower region, in which the housing profile 14.1 according to the previous embodiment is also used, but the movements of the pulling cable unit 80 are effected via a second unit 132 with a preceding transmission 134, wherein the tension cable unit 80 aufbeziehungsweise on / from a roller 136 can be unwound and is fed via the guide roller 162 of the second pivot bearing unit 122. According to the displaceably mounted on the housing profile 14.1 bolt 32, a first unit 86 is assigned, which causes its training or retraction for Verbeziehungsweise unlocking the rotational movement of the roller device 20. Furthermore, a chamber 72 is shown in FIG. 20 in the upper left-hand area of the housing profile 14.1, within which there is an accumulator 138 which supplies the units 132, 86 designed as electric motors with power. Schematically, a relay 74 is shown in Figure 20 within the housing profile 14.1, wherein the entire electronic interconnection and wiring in Figure 23 is not shown in detail. The actuated aggregates 132 and 86 take place via manually operable switching units not shown in detail in FIG. 20, which are preferably arranged on the handle profile area 12.

In Figure 24, another embodiment of a hand roller device 10.7 is shown in fragmentary form, showing a further constructive embodiment variant with respect to the blocking unit. In the right-hand end region of the axle profile region 16, the first rotary bearing unit 24.1 already described above (FIG. 7) is arranged in a rotationally fixed manner. On the first pivot bearing unit 24.1, the first rotor unit 22.1, which is also already described above (FIG. 8), is rotatable, but displaceably arranged in the longitudinal direction. On the flange 30 of the first rotor unit 22.1 acts via a hinge point 73 in the transition region between the transition profile region 14 and the axle profile area 16 hingedly connected locking lever 59, which can be locked in two pivotal positions via the also described above clamping spring unit 35 (Figure 25, 26).

If the locking lever 59 is in the left-hand (solid) position in FIG. 27, the first rotor unit 22.1 is displaced relative to the first rotary bearing unit 24.1 such that the latching projections 41 of the first rotor unit 22.1 are disengaged from the latching recesses 43 of the first rotary bearing unit 24.1 is called not shown in Figure 27 roller device is freely rotatable.

If now the locking lever 59 is pivoted into the right (dashed) position in FIG. 24, the latching projections 41 snap into the latching recesses 43 due to the action of the first elastic unit 56 or the elastic properties of the sponge body in a specific rotational position and the roller device is blocked altogether , This embodiment can be implemented constructively in a particularly simple manner, ensures easy operation, a permanently reliable function and enables economical production.

In an embodiment not shown, the provision of a first rotary bearing unit is dispensed with. The first rotor unit is rotatably mounted directly on the axle profile area and has a projecting in the longitudinal axis of the circumferential flange with outwardly open recesses, which may be distributed circumferentially distributed in a grid. The locking lever is designed as a bracket, which has at the level of the hinge point on both sides inwardly facing projections, which can be brought to Blockierzwecken with appropriate lever actuation and position of the first rotor unit with the recesses of the flange.
