TECHNICAL AREA

The present invention relates to a hand roller device for removing and / or picking up and / or applying liquids, such as water, paint or the like, from or to substrates with a stem profile area, an axis profile area, a deflecting profile area which is between the stem profile area and the axis profile. fil range runs, and a rotatable on the axis profile area roller device.

Such hand roller devices are used in various embodiments in households for cleaning purposes and / or paint application purposes.

STATE OF THE ART

In the German utility model DE-GM 73 33 567 a sponge with a handle-like handle is disclosed, the

Sponge body is held between holding elements fastened at the ends in each case to the outer or inner part and can be pressed together by moving the outer and inner part. The sponge body is compressed against the force of a compression spring. The

The sponge itself is not designed to be rotatable. At least one recess is provided in the sponge body, into which a cleaning agent can be introduced, which gradually dissolves under the action of water. This means that cleaning agents do not have to be added directly to the cleaning water. DE-OS 1503 886 describes a double sponge hand wiper device which has laterally pivotably connected legs at the lower end of its wiper handle, which have horizontally round short bends or bolts at their ends, which serve both as pressing elements and sponge holders. The sponge can be compressed by means of these pressing elements. The sponge is rectangular and there is no rotatability of the sponge.

British patent specification GB-PS 704348 discloses a device for applying sponges, the actual sponge body being arranged between two plates which can be moved towards one another. A rotatability of the sponge body is not possible with this construction.

US Pat. No. 3,171,152 discloses a hand cleaning device with a triangular sponge body. By manually moving a thrust washer in the axial direction, the sponge body can be pressed together and the liquid absorbed by it can be applied. A rotatability of the sponge body due to its triangular shape is not possible.

U.S. Patent 3,374,498 discloses a quadrangular one

Sponge body, which can be moved by a pressure plate onto a fixed pressure plate by means of a special displacement unit with flexible wall mounted on a handle, whereby the sponge body arranged between them is pressed out.

BE 55652 describes an inking roller which has a color reservoir. There are recesses in the roller wall that can be closed by flaps. There is a cuff on the axis of rotation that is connected to flaps via swing arms. The cuff can be moved axially from the outside via a pulling cable device, as a result of which the flaps move via the swing arms and the recesses in the roller wall are opened to allow ink to pass through.

A paint application device is described in FR 1100842, in which the rotating part can be releasably locked via a form-fitting disengageable coupling.

Advantageous refinements and developments are the subject of the dependent claims.

The hand roller device according to the invention is accordingly characterized in that the axis profile region is surrounded by an elastic sponge body extending in the longitudinal axis direction, in the axis profile region on the inside in the transition region from the axis profile region to A first rotor unit is arranged on the steering profile region, on which there is a second rotor unit on the outer end face of the roller device opposite the first rotor unit, which is rotatably mounted on the axis profile region so as to be longitudinally displaceable, on the second

Runner unit acts a flexible traction device, which is arranged within the axis profile area, the transfer profile area and the stem profile area and when loaded by means of a displacement unit or a unit, an axial longitudinal displacement of the second rotor unit and thus an axial compression of the sponge body takes place.

A particularly preferred construction of simple design is characterized in that the second rotor unit is connected to a second rotary bearing unit, which is non-rotatably and longitudinally displaceable on the axis profile region and to which the traction device is connected.

According to a first variant of the invention, the hand roller device is accordingly characterized in that blocking means are provided for selectively unlocking or locking the rotary movement of the roller device. As a result of this measure, a hand roller device which is usually intended for applying liquid, in particular paint, can also be used as a wiping or cleaning tool.

The blocking means can be actuated, for example, manually or by a first unit that can be acted upon by an operator. The unit is preferably designed as an electric motor. A structurally particularly simple configuration, which can be produced economically and ensures a permanently reliable function, is characterized in that a first rotor unit is connected to the roller device, at least on one end face, which is rotatably mounted on the axis profile area and has a first profile cross-sectional contour and in the area of the first rotor unit there is a non-rotatable blocking unit with a corresponding counter-profile cross-sectional contour, with the first profile cross-sectional contour of the first rotor unit being able to be positively and releasably engaged with the counter-profile cross-sectional contour of the blocking unit for locking.

A particularly advantageous embodiment is characterized in that the first rotor unit has a circumferential flange and the first profile cross-sectional contour has at least one recess, in particular recesses that are present in a predetermined grid, and the counter-profile cross-sectional contour of the blocking unit has one

Alternatively, the projection unit can be arranged on a pivoting lever which can be locked in the locking or unlocking position and which can be operated either by hand or by foot with a hand roller device with a long handle.

A preferred embodiment, which is structurally particularly simple, ensures a permanently reliable function and at the same time is easy to operate, is characterized in that the first / second pivot bearing unit is arranged as non-rotatably on the axis profile area Hub unit is formed. In a particularly advantageous manner, a further embodiment variant can be implemented, which is characterized in that a pivotable locking lever is present which acts directly on the first rotor unit and by means of it

The first profile cross-sectional contour of the first rotor unit can be brought out of engagement with the counter-profile unit of the blocking unit.

A particularly preferred embodiment, which can be produced economically, is characterized in that the stem profile area, the transfer profile area and the axis profile area are designed as a one-piece hollow profile, the traction device or the Bowden cable preferably being arranged within the hollow profile so that it protects against mechanical damage , Pollution or similar influences that can impair its function are absolutely reliably protected.

The connection of the rotor unit and the rotary bearing unit is preferably liquid-tight, so that the rotating parts are reliably and permanently protected against contamination.

The connection of the second rotor unit or the second rotary bearing unit to the rotor roller can be made detachable, so that the rotor roller can be exchanged without any problems.

A very important advantage of the invention

Hand roller device is that it can be used economically and time-saving as a cleaning tool. When the roller device is locked, wipe over the surface to be cleaned. Is now the dirt holding volume of the Schwa mkörpers, exhausted in the area in which he is in contact with the surface, the roller device is unlocked in a simple manner, then rotated for example by 45 ° (old degree) and then locked again. The cleaning process can then be continued. This procedure can be repeated a total of eight times until practically the entire circumferential contour of the sponge body is saturated with dirt. Only then is it necessary to immerse the sponge body in a water container and then press it together for cleaning purposes.

The traction device can also be designed in a simple manner as a traction rope, but for this purpose deflection rollers must be present within the profile areas, in particular in the deflection profile area.

In order to ensure a permanently reliable function in which the extension movement of the sponge body is advantageously supported after compression, a first elastic unit, in particular a spiral spring, is arranged between the first rotor unit and the second rotor unit.

In addition, a second elastic unit, in particular a spiral spring, can also be arranged between the first pivot bearing unit and the second pivot bearing unit.

In accordance with a preferred embodiment, it is structurally particularly advantageous to design the hand roller device in such a way that the first pivot bearing unit and / or the second pivot bearing unit is designed as a hub unit that is non-rotatably and longitudinally displaceably mounted on the axis profile region. The hand roller device according to the invention is characterized in that the hub unit has an inward-looking guide projection unit which engages in an axially extending slot in the axis profile area and to which the pulling device or the Bowden cable is anchored.

A particularly advantageous embodiment variant, which enables particularly simple operation, is characterized in that the displacement unit is designed as a handle that can be detachably locked in the handle profile area.

In order to reduce the force required to compress the sponge body, a preferred embodiment is characterized in that a third elastic

Unit, which is designed in particular as a spiral spring, is present, which puts the displacement unit or the handle under tensile stress in such a way that the required tensile force for pressing out the sponge body is reduced. All profile areas can be made of plastic or metal. The elastic sponge body is preferably designed as a viscose sponge, which achieves very good results with regard to its liquid-absorbing effect.

A roller device that is particularly easy to handle is characterized in that the stem profile area is arranged essentially at right angles to the axis profile area.

In an alternative embodiment, the first rotor unit is also designed in a longitudinally displaceable direction towards the second rotor unit, so that the sponge body can also be pressed together from this side.

Further embodiments and advantages of the invention result from the features further specified in the claims and from the exemplary embodiments specified below. The features of the claims can be combined with one another in any way insofar as they are not obviously mutually exclusive.

WAYS OF CARRYING OUT THE INVENTION

FIG. 1 schematically shows a hand roller device 100 in section, which has a rotatable roller device 20 with an elastic cylindrical sponge body 60, the sponge body 60 being compressible. The principle of operation of the compression is described below.

The hand roller device 100 has a straight stem profile area 12, an adjoining one

Transfer profile area 14, which initially runs obliquely downward and then curved by approximately 180 ° (old degree), and a straight-line axis profile area 16 adjoining the transfer profile area 14. The profile areas 12, 14, 16 are bent by a single piece

Round tube profile formed. The axis profile area 16 is substantially perpendicular to the handle profile area 12. In the transition region between the transition profile region 14 and the axis profile region 16, a first rotary bearing unit 24 is provided on the axis profile region 16 in a rotationally fixed manner, on which a first rotor unit 22 is rotatably mounted. The first rotor unit 22 has a protruding circumferential flange 30 which abuts the sponge body 60 on the end face. Furthermore, fixing pins 31 are formed on the flange 30 in the direction of the sponge body 60, which fix the sponge body on the first rotor unit 22. The fixing mandrels can also be dispensed with.

On the opposite outer end region of the axis profile region 16 there is a second rotational bearing unit 28 which is fixed against rotation and which is longitudinally displaceable in the axial direction and on which a second rotor unit 26 with a circumferential flange 30 is rotatably mounted. This design ensures that the roller device 20 can be reliably and permanently rotated about the axis profile region 16.

The compressibility of the sponge body 60, which is preferably designed as a viscose sponge, is ensured by the following components. On stem profile area 12 there is a displaceable unit 96.1, which is designed as a handle 76. The handle 76 can be moved down to a stop unit 78. A flexible tension element 70, which is designed as a Bowden cable 70, is arranged within the stem profile area 12, the transition profile area 14 and the axis profile area 16. One end of the cable of the Bowden cable 70 is anchored to the handle 76. One end of the envelope of the Bowden cable 70 lies 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 envelope of the Bowden cable 70 is connected to the first pivot bearing unit 24. A first elastic unit 56, which is designed as a helical spring, is arranged between the first rotor unit 22 and the second rotor unit 26. The first pivot bearing unit can also be dispensed with. In this case, the first rotor unit is rotatably mounted directly on the axis profile area.

If the handle 76 is now pulled upwards in the direction of the arrow ZI along the handle profile area 12, this displacement 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 the arrow Z2 and counter to the action of first elastic unit 56 and the elasticity of the sponge body 60 compress it, so that previously absorbed liquid in the sponge body 60 is pressed out of it.

If the handle 76 is released after the sponge body 60 is compressed, the sponge body 60 expands again due to its elastic material properties and with the support of the elastic unit 56, so that the handle 76 is pushed down until it strikes the stop unit 78. In this state, the sponge body 60 is completely relaxed and can be used for further liquid absorption or other cleaning purposes.

FIG. 3 shows a first design variant of a hand roller device 10.1 which implements the above principle. The same components have the same reference numerals and are not explained again.

The first and second rotor units 22, 26 are cup-shaped with a projecting flange 30, the first and second rotary bearing units 24, 28 being arranged within the pot. The pivot bearing units 24, 28 are designed as hub units. The second pivot bearing unit 28 has an inwardly pointing guide projection unit 62 which engages in a slot 64 in the axis profile region 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 is on the one hand non-rotatable and on the other hand longitudinally displaceable on the axis profile region 16.

A second elastic unit 58, which is preferably in the form of a helical spring, can be provided between the first rotary bearing unit 24 and the second rotary bearing unit 28 to assist.

The displacement unit 96.1 is a sleeve unit around the

The web section area 12 is formed around and has an inward-pointing 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 provided on the web profile region 12. In a variant shown schematically in FIG. 4, the slot 104 has transverse recesses 106 which are spaced in a grid-like manner and into which the projection unit 102 can be positively engaged, so that the displacement unit 96.1 can be in almost any position

Position on the stem profile area 12 can be locked.

In order to reduce the effort required to squeeze out the sponge body 60, according to a preferred embodiment variant, a third elastic unit 66, which is preferably designed as a helical spring, is present between the displacement unit 16.1 and the upper end region of the handle profile region 12, which displaces the displacement unit 26.1 to the stop unit 78 striking condition under tensile stress.

In Figure 3, the elastic sponge body 60 is shown in a longitudinal section and a side view. A shaft contour 108 is superimposed on the cylindrical circumferential contour. The sponge body 60 also has a continuous cylindrical inner recess 61. In this inner recess 61, the axis profile region 16 with the first elastic unit 56 is arranged.

The hand roller device 10.1 furthermore has a blocking unit by means of which the rotary movement of the roller device 20 can be locked or unlocked as desired. The blocking unit has a swivel lever 36 which is designed as a U-bracket and whose web regions are arranged so as to be rotatable about an axis of rotation 37 perpendicular to the axis direction of the axis profile region 16. The pivot lever 36 can be pivoted from a locking position into an unlocking position about the axis of rotation 37, the unlocking position being shown in broken lines in FIG is. On the swivel bracket 36 there is a cantilever element 39 arranged inclined to the longitudinal axis of the swivel bracket 36, on the free end of which a projection unit 32 is formed. At the same time, the first rotor unit 22 has four continuous recesses 34 in its flange 30 which are offset by 90 ° (old degree) in the circumferential direction and into which the projection unit 32 can be positively engaged depending on the positioning. To block the roller device 20, the pivot lever 36 is moved from the unlocking position (dashed line) into the locking

Position (solid representation) swiveled. If the projection unit 32 does not meet a recess 34, this initially rests on the outer surface of the flange 30 in an elastically pressing manner due to the inclined arrangement of the cantilever element. By slightly rotating the roller device 20, the projection unit 32 can be made to coincide with a recess 34, so that the projection unit 32 then snaps into the recess 34 and the locked state is present, since then the first rotor unit 22 can no longer rotate.

The fixing of the pivot lever 36 in the unlocking or locking position (detail C in FIG. 2) is shown in more detail in FIGS. 22 and 23. The bow-shaped swivel lever 36 encompasses the transfer profile area 14. On the transfer profile area 14, a clamping spring unit 35 is connected on the outside, one end 47 of which engages under the outer wall of the transfer profile area 14 and the other end 48 on the outside by means of a screw 49

Transition profile area 14 is attached. A web of the swivel lever 36 is arranged between the outer wall of the transfer profile area 14 and the inner wall of the clamping spring unit 35. In the unlocking position 67 and in the locking position 68 is the distance between Kle mfedereinheit 35 and transition profile area 14 selected slightly larger than the diameter of one bracket of the pivot lever 36. Between the two positions 67, 68, the distance is chosen to be smaller, so that the pivot lever can only be pivoted from one position to the other by applying a force ( Arrow S), that is, a reliable locking of the desired position is guaranteed.

The third embodiment variant of a hand roller device 10.3 shown in FIG. 5 works for compressing the roller body 20 according to the same principle as the devices described above, but the blocking effect is produced in a different way and the displacement unit 96 is designed 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 rotary bearing unit 24.1, 28.1. The first rotor unit 22.1 is shown in FIG. Instead of the mandrels, the rotor unit 22.1 has inwardly facing wall elements 63 formed on the flange 30 and distributed circumferentially by 90 ° (old degree), which engage corresponding recesses in the sponge body 60. In the pot base of the rotor unit 22.1, projection units 41 are formed in the form of a grid on the circumference.

The first rotary bearing unit 24.1, which is shown in FIG. 9, is arranged in the pot region of the first rotor unit 22.1. It has, on the side facing the locking projections 41, corresponding locking recesses 43 into which the locking projections 41 are positively engaged by a relative displacement of the two components can, as soon as the rotational position of both components corresponds accordingly. The second rotor unit 26.1 or the second rotary 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 in a longitudinally displaceable manner on the axis profile region 16. These pivot bearing units also have an inwardly shaped molded projection unit 62 which engages in the slot 64 of the axis profile region 16 and to which the cable of the Bowden cable 70 is anchored in the case of the second pivot bearing unit 28.1.

If the sponge body 60 is in a relaxed state, the latching projections 41 of the rotor units 22.1 or 26.1 are out of engagement with the latching recesses 43 of the first pivot bearing unit 24.1 or 28.1, that is to say that the roller device 20 can be rotated.

If the blocking effect is to be generated, the displacement unit 96 is displaced upwards by dimension 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 results in a relative shift 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 engage in a form-fitting manner, possibly with a 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 non-rotatable second rotary bearing unit 28.1 is positively coupled to the second rotor unit 26.1, that is, rotation of the roller device 20 is no longer possible. In the interior there is an elastic spring element 45 on the outside in the transfer profile area 14, which is designed as a circumferential helical spring, which is supported on the transfer profile area 14 via a projection unit 53 and via a displaceable disk 46 on the end area of the first rotor unit 22.1. When the displacement unit 96 is displaced upwards by the dimension V (FIG. 5), the locking projections 41 and the locking recesses 43 of the first rotor unit 22.1 and the first rotary bearing unit 24.1 also come in

Intervention. By means of the spring element 45, it is possible to set the force required to move the displacement unit 96. This is done in a simple manner by turning the coil spring 45. The spring element 45 causes the first rotor unit 22.1 to disengage from the rotary bearing unit 24.1 when it is unlocked, since its spring force is greater than the spring force of the first arranged between the rotor units 22.1, 26.1 elastic unit 56.

It is also possible for the blocking to take place only on one end face of the roller device. For example, the first rotary bearing unit can be designed as a normal fixed unit on which the first rotor unit is rotatably arranged. The spring element 45 can then be omitted completely.

In the stem profile area 12, a connecting sleeve 55 is connected below the displacement unit 96, which serves on the one hand as a lower stop for the displacement unit 96 and within which the Bowden cable 70 is guided out of the interior of the web profile region 12 and the cable of the Bowden cable 70 is guided further up to Anchoring position on the displacement unit 96. The displacement unit 96 is shown in more detail in FIGS. 11 a, b, c. In some areas it is designed as a spreading unit. In its lower end region, the displacement unit 96 has an embossed circumferential groove 110, in which two elastically expandable locking rings or tension rings 116 (see FIGS. 10 a, b, c) are arranged, which ensure that the displacement unit 96 reliably on the stem profile region 12 is locked in place.

The displacement unit 96 has four slots 112 which are open in the circumferential direction and are radially offset by 90 ° (old degrees) and open downwards. The underside anchoring position of the cable of the Bowden cable 70 on the displacement unit 96 is indicated in FIG. 11 b) with the reference symbol 114. In order to enable the displacement of the displacement unit 96, which is also designed as a handle, along the stem profile area 12, the spreading lever 98 shown in FIG. 14 a to d is used. The spreading lever 98 has an outwardly inclined grip region 99 and a molded region 101 which is formed on the underside and comprises the stem profile region 12 in a semicircular shape. In its end region, the molding region 101 has folding regions 103 which run inward at right angles, these two opposite folding regions 103 engaging in the opposite slots 112 of the displacement unit 96. If the handle area 99 is now pressed in the direction of the arrow X (see FIG. 9), this leads to an expansion in the area of the clamping rings 116 due to the leverage effect, so that the displacement unit as a whole can be moved in the longitudinal direction on the handle profile area 12, for example in the direction of the arrow Z (FIG 5) to compress the sponge body. As soon as the spreading lever 98 is released, the clamping rings 116 again ensure that the displacement unit is securely locked on the handle profile region 12 in this current position. 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, the telescopic tubes being locked in place by means of an eccentric lever unit 118. There are two additional handles 120 in the telescopic area. In contrast to the hand roller devices described above, the axis profile area 16.1 is itself telescopic, which means that it is not necessary for the sponge body 60 to be compressed to have a second pivot bearing unit 122 which must be longitudinally displaceable on the axis profile area 16.1. The cable end of a Bowden cable 70 is also anchored to the "stationary" second pivot bearing unit 122, the other end of which is operatively connected to the displacement device 96. A second rotor unit 124 with a circumferential flange 126 is rotatably mounted on the second rotary bearing unit 122.

On the end face opposite the free end face of the roller device 20, a first rotor unit 128 is rotatably mounted on the telescopic axis profile area 16.1. The first rotor unit 128 also has a flange 130 with continuous recesses 132, an existing bolt 32, which is operatively connected to a further Bowden cable 40, being insertable into one of these recesses 132 for blocking purposes, the other end of the Bowden cable being connected to a further displacement unit 46 is connected, which is arranged displaceably in the longitudinal direction on the connecting sleeve 55. To block the roller device 20 in the hand roller device 10.4 according to FIG. 15, the further displacement unit 46 must therefore be displaced downward in the direction of the arrow U, as a result of which the bolt 32 is extended by means of the Bowden cable 40 and engages in one of the recesses 132. FIG. 14 shows a fifth embodiment variant of a hand roller device 10.5, which basically has the same structure as the hand roller device 10.4 according to FIG. 13. Therefore, the same components have the same reference numerals and are not explained again. The main difference is that it is not the displacement unit 96 or the further displacement unit 46 that is used to generate the movement of the Bowden cable, but rather an assembly 144, in particular an electric motor, which can be controlled via corresponding switching units 140 or 142 in order to unlock the roller device 20 or to lock or compress the sponge body 60.

The sixth embodiment variant of a hand roller device 10.6 shown in FIG. 15 is similar in structure to the hand roller device 10.4 according to FIG. 13 and also has a telescopic axis profile region 16. Both rotor units 124, 128 are rotatably mounted directly on the axis profile area 16.1. However, this one

Embodiment of the handle profile area 12 is kept relatively short and the sponge body 60 is compressed by means of an assembly 146 present in the upper end area of the handle profile area 12, which acts on the second rotor unit 124 via the Bowden cable 70. The

Blocking also takes place via the bolt 32 acted upon by the Bowden cable 40, the displacement unit 46 connected to the other end of the Bowden cable 40 being constructed slightly differently, namely as a slide switch. Instead of the assembly 146, there can also be a pull ring 65 connected to the Bowden cable (dashed line in FIG. 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 sieve or grid 152 on the top side. According to FIG. 16 b, it is also possible to design the first rotor unit 22 or the first rotary bearing unit 24 to be longitudinally displaceable, so that the sponge body 60 can also be compressed manually as a result.

FIG. 17 shows schematically how liquid can be removed from a first container 154 by means of the hand-roller device 10.1 described and how it can be transferred into a second container 156. Thus, first the hand roller device 10.1 is inserted with the sponge body 60 compressed into the first container 154 below the liquid level and then the sponge body 60 is relaxed (arrow S). As a result, it absorbs liquid. In this state, the hand roller device 10.1 is brought into the second container 156 and then the sponge body 60 is pressed together by moving the displacement unit 96 (arrow D), so that the absorbed liquid exits into the second container 156.

FIGS. 18 and 19 show a further embodiment of a hand roller device 90, the mode of operation of which essentially corresponds to the mode of operation of the hand roller device 10.4 according to FIG. 13 with a telescopic axis profile area 16.1, but a transfer profile area 14.1 is used, which is designed as a housing profile, and the Bowden cable has been replaced by a simple traction cable unit 80 which within the housing profile 14.1 via pulleys 160, 161, 162 of the second rotary bearing unit 122 is supplied. The blocking effect is also made possible by a bolt 32 which is mounted in a longitudinally displaceable manner on the housing profile 14.1 and can be brought into engagement in a recess 132 of the first rotor unit 128, a spring lever 164 accessible from outside the housing profile 14.1 acting on the bolt 32, 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 to the telescopic axis profile area 16.1 in a liquid-tight manner.

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 traction cable unit 80 take place via a second unit 132 with an upstream gear 134, the traction cable unit 80 can be wound up or unwound from a roll 136 and is fed to the second rotary bearing unit 122 via the deflection roll 162. Correspondingly, the bolt 32, which is displaceably mounted on the housing profile 14.1, is assigned a first unit 86, which causes its extension or retraction to lock or unlock the rotary movement of the roller device 20. Furthermore, in FIG. 20, in the upper left area of the housing profile 14.1, a chamber 72 is shown, within which there is an accumulator 138, which supplies the units 132, 86 designed as electric motors with current. A relay 74 is shown schematically in FIG. 20 within the housing profile 14.1, the entire electronic interconnection and wiring not being shown in more detail in FIG. The acted upon units 132 and 86 take place via manually operable switching units, not shown in FIG. 20, which are preferably arranged on the handle profile area 12. A further exemplary embodiment of a hand roller device 10.7 is shown in detail in FIG. 24, which shows a further design variant with respect to the blocking unit. In the right end region of the axis profile region 16, the first rotary bearing unit 24.1 already described above (FIG. 7) is arranged in a rotationally fixed manner. The first rotor unit 22.1, which has also already been described above (FIG. 8), can be rotated on the first rotary bearing unit 24.1, but is displaceable in the longitudinal direction. A locking lever 59, which is articulated via a hinge point 73 in the transition area between the transfer profile area 14 and the axis profile area 16, acts on the flange 30 of the first rotor unit 22.1.

If the locking lever 59 is in the left (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 out of engagement with the latching recesses 43 of the first rotary bearing unit 24.1, that is called the roller device not shown in detail in Figure 27 is freely rotatable.

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

In an embodiment not shown in detail, the provision of a first pivot bearing unit is dispensed with. The first rotor unit is rotatably mounted directly on the axis profile area and has a circumferential flange which projects in the longitudinal direction of the axis and has recesses which are open to the outside and which can be arranged in a grid pattern around the circumference. The locking lever is designed as a bracket which, at the level of the articulation point, has inward-facing projections which can be brought into engagement with the recesses in the flange for blocking purposes if the lever is actuated and the first rotor unit is in position.
