Abstract

The invention relates to a roller holder (150), comprising a base (12) with a hollow-cylindrical receiving element (14) extending therefrom and receiving the roller (54), as well as a pressure means (200) which rests on the outside of the roller and is designed in such a way that this is tilted in the direction of this when a section of the roller (54) is torn off.

Description

The invention relates to a roll holder, comprising a base element, such as a base, with a cylindrical, in particular hollow-cylindrical, receiving element that extends from the base element and receives the roll, as well as a pressure medium that rests on the outside of the roll, which is guided in the base element in the direction of the roll and is subjected to a force.

Roll holders are used to hold paper wound on a sleeve, such as a core sleeve, which can be referred to quite generally as a cylindrical hollow body, from which sections are severed or torn off in order to be able to use them.

In order to ensure that the roll does not rotate when it is torn off or that it does not rotate after it has been torn off, it is known that a pressure medium acts on the outer peripheral surface of the paper, which pressure medium can be adjusted in the direction of the roll under spring force. A translatory movement of the pressure medium took place. Translatory means that the pressure medium is adjusted along a straight line or also along a path that has a curvature and runs radially in relation to the element receiving the paper roll.

A roll holder of the type described above is the DE 20 2017 100 728 U1 refer to. The pressure means has a pressure element that extends largely over the height of the paper roll and that starts from a carriage element that can be adjusted within a guide of a base element, referred to as a base.

A similar construction follows from DE 202 02 225 U1 , according to which a rod-shaped pressure element acts on the outer surface of a paper roll.

The WO 2011/032302 A2 relates to a paper roll holder in which a paper roll is subjected to a force by means of a holding arm which can be inserted into a pivotable receiving sleeve of a holding adapter which extends from a base plate.

After U.S. 2007/0194168 A1 a roller mount is provided with a pressure medium acting on a roller. The pressure medium is connected to a spring element so that it can be pivoted about an axis.

The U.S. 2008/0308667 A1 describes a tiltable pressure means of a roller mount to act on a roller.

A roll holder with a lever that can be pivoted by means of a spring and acts on a roll is the CN 202386604 U refer to.

The disadvantage of corresponding roll holders is that when it is torn off, it is not ensured that the pressure medium acts on the roll to the extent required to enable reliable tearing off.

The present invention is based, among other things, on the object of further developing a roll holder of the type mentioned at the outset in such a way that it is ensured that the roll is fixed when it is torn off in such a way that a secure separation of a paper section is made possible, especially when there are high tensile forces on the paper.

To solve the problem, the invention essentially provides that the pressure medium is designed in such a way that this when tearing off or separating a section of the Role is tilted in the direction of this, wherein the pressure means has a first leg extending along the receiving element and a second leg extending along the base element with a portion projecting towards the bottom surface of the base element, about which the pressure means can be tilted.

In particular, the invention is also characterized by a roller holder, comprising a base element, such as a base, with a cylindrical, in particular hollow-cylindrical, receiving element that extends from the base element and receives the roller, as well as a pressure medium that rests on the outside of the roller and can be displaced translationally in the base element in the direction of the roller is guided and subjected to a force, the pressure medium being designed in such a way that it is tilted in the direction of the latter when a section of the roller is torn off or separated.

According to the invention, it is provided that the pressure means is tilted in the direction of the paper roll during the tearing off, so that pressure is applied to the required extent. Consequently, a desired tearing off of a section is made possible.

Tear off includes any manner of severing a section from the roll.

It is provided in particular that the pressure means has a first leg extending along the receiving element and a second leg extending along the base element with a section protruding in the direction of the bottom surface of the base element, around which the pressure means can be tilted.

A tilt angle of between 5° and 10°, in particular of or approximately 7°, is preferred.

The pressure means consists of an L-shaped element which is composed of the first and second legs and is tiltable about an axis which is spaced from the point of connection between the first and second legs. This ensures that the pressure medium is tilted away from the roller with its first leg when a constraining force is not acting on the second leg in the vertical direction, with the first leg then being parallel or approximately parallel to the longitudinal axis of the receiving element and thus the role should run.

In order to ensure a desired alignment of the pressure medium in relation to the longitudinal axis of the receiving element, it is provided in a further development that the second leg has a first support extending in its longitudinal direction, which is supported on an inner bottom surface of the base element when the pressure medium is tilted.

In addition, the second leg should have a second support, which is spaced apart from the first support and runs along it and, when the pressure medium is not tilted, is supported on an inner head surface of the base element.

In particular, the first support and the second support should enclose an acute angle in a plane running perpendicularly to the inner floor surface.

Finally, in a further development, it is provided that the second leg has a third support, which extends along, in particular parallel or approximately parallel, to the first support and onto which a rod-shaped element, such as a threaded rod, extending inside the receiving element, is attached for tilting the Pressure medium then acts when this is subjected to a constraining force in the direction of the base element.

In order to tilt the pressure medium, the invention provides that a rod-shaped element, such as a threaded rod, acts on the second leg so that the pressure medium is tilted in the direction of the roller, so that the roller is prevented from rotating further to the required extent and a section is thus prevented from being reliably separated is made possible.

Irrespective of this, provision is made in particular for the first leg to have a spring element which always rests against the peripheral surface of the roll even when the pressure medium is not tilted and thus prevents uncontrolled rotation of the roll when a section is pulled off.

For this purpose, it is provided in particular that the first leg has a frame, in particular having a rectangular shape, within which a to the Frame adjustable and extending in the longitudinal direction of the first leg spring element.

In particular, it is provided that the spring element is a leaf spring which is integrally formed in the pressure means and is unconnected to the upper transverse limb of the frame with respect to the end remote from the second limb and extends along the side of the transverse limb facing away from the roller.

In order not to impede the pulling off, the longitudinal edges of the leaf spring running in the longitudinal direction of the frame should be rounded off or chamfered.

In order to enable the pressure medium to bear well against the roller, provision is made for the first leg to have a concave geometry in its region which bears against a roller.

Irrespective of this, the invention is particularly characterized in that the second leg has two side legs and an intermediate wall running between these and its upper and lower longitudinal edges forming the third support, the upper longitudinal edges being the second support and the lower longitudinal edges being the first support.

The side legs run parallel to one another and perpendicular to the base element.

In order for the pressure medium to be adjusted radially in relation to the receiving element, whether along a straight line or along a line that is curved at least in sections, it is provided that a section of the pressure element, in particular a section of the second leg, is inserted into a connecting link slot designed as an elongated hole engages, which extends in the longitudinal direction of a leg element, which is pivotable about an axis that runs in the area of the leg element that lies away from the connecting link slot, and that the leg element is connected to a spring element for pivoting it in such a way that the pressure element is pressurized in the direction of the roller.

The subject matter of the invention is also a roll holder, in particular a kitchen roll holder, comprising a base element, such as a stand, with this outgoing hollow-cylindrical first body with an opening remote from the bottom section, a first element that can be adjusted within the first body along its longitudinal axis and is subjected to a force in the direction of the opening, which on the opening side has a second element that preferably tapers at least in a conical manner in the direction of the body and has an underside facing it, such as Handle, has or is connected to it, with a force acting on the second element in the direction of the base section, a sleeve surrounding the first body, such as the core sleeve of a kitchen roll, being fixable and rotatable around the first body when no force is applied. The first body is the socket receiving the sleeve.

A corresponding role holder is the U.S. 7,401,749 B2 refer to. The conical or frustoconical underside is the underside of a handle, from which a hollow shaft section extends, which extends inside a tube forming a hollow-cylindrical first body, and which experiences a force being applied away from a base by means of a spring surrounding the hollow shaft. If a kitchen roll is slipped onto the tube, it is prevented from turning if the handle is adjusted against the spring force in the direction of the base of the floor, whereupon the conical underside acts directly on the kitchen roll.

Kitchen roll holder or paper roll stand after DE 20 2008 008 599 U1 and DE 36 13 988 A1 work according to the same principle, ie that a handle, albeit plate-shaped, rests against a roll of paper when the paper is to be prevented from being pulled off. The handle can be adjusted against a spring force or via a thread.

The disadvantage of such holders is that, to fix the rollers, the handles act directly on the paper to be torn off, so that pressure points can arise that can affect ease of movement when peeling off. If the fixing is done by applying spring force to the handles, only rolls of the same sleeve length can be accommodated in order to ensure that the handles actually act on them.

The DE 691 16 267 T2 a paper towel dispenser with a brake can be seen. This comprises two sleeves that can be plugged into one another and are connected by friction to a core roll of a paper roll. The sleeves and thus the core roll are prevented from rotating if the sleeves are prevented from rotating by means of a braking device by axially adjusting it in the direction of the sleeves.

According to the invention, a roll holder of the type explained above is developed in such a way that it is possible to fix the roll held by the holder with structurally simple measures, with rolls of different lengths also being able to be used if necessary. When fixing, it is ruled out that the material to be peeled off experiences pressure points when fixing takes place.

For this purpose it is essentially provided that the first body is slotted lengthwise starting from the edge of the opening such that when the second element is adjusted in the direction of the base section and the underside interacts with the body, the latter expands circumferentially.

Deviating from the prior art, the second element, designed in particular as a handle, does not act directly on the material to be removed, but on the first body such as a hollow cylinder or tube, which is surrounded by the sleeve containing the material to be removed. The material does not have to be just paper. Rather, all tearable materials come into question, as well as plastic foils, metal foils such as aluminum foils. In particular, however, a use for a kitchen roll is given.

It is admittedly known that expanding a tube prevents a tube of a paper roll held by it from rotating further. In that regard, on the DE 200 20 532 U1 to refer. However, the opening area is not spread, but strips running between sections of the pipe are pushed apart.

Because the first body is in contact with the sleeve of the material to be removed by spreading the first body, rotation of the sleeve and thus removal of the material is prevented in a simple manner, so that the latter can be torn off.

In particular, it is provided that a spring element, such as a helical or cup spring, acts on the first element, such as a rod, in particular a threaded rod, and extends between a first section emanating from the first element and a stationary stop.

In order to support the spring element with structurally simple measures, it is provided that the stationary stop is an intermediate wall of the first body running along, in particular parallel to, the base section, or a further element extending from this.

It is provided that the first element passes through the intermediate wall and that a second stop, such as a cap surrounding the free end of the first element, in particular a cap nut with a collar, emanates from the first element and is impenetrable between the intermediate wall and the base section and the intermediate wall runs.

In order to be able to axially adjust the first element, such as the rod or an element that has the same effect, to a sufficient extent, i.e. to enable a sufficient stroke, so that the underside of the second element, in particular the handle, which is conical or cylindrical at least in some areas, allows the necessary spreading of the longitudinally slotted first body, it is further provided that the base section in the axial extension of the first element has a recess for immersing the free end of the first element or the stop.

In order to enable easy expansion, i.e. spreading, of the hollow-cylindrical first body, it is provided in a further development that the first body has several longitudinal slots running uniformly around its circumference, the respective lengths of which are preferably over or approximately over 1/3 to 2/3 of the Height, preferably about half the height of the first body.

Preferably 3 or 4 longitudinal slots are provided.

This means that rolls of different lengths can be easily accommodated by the holder.

In particular, the invention provides that the opening side of the first body is expanded in the manner of a tulip.

This enables smooth adjustment and sliding along the underside, which is conical or truncated at least in sections, and the opening area of the hollow-cylindrical first body.

A further proposal provides that the first element is surrounded by a hollow-cylindrical second body extending inside the first body with an integral spring element running on the base section side, via which the first element is subjected to a force in the direction of the opening.

This construction eliminates the need to mount a separate spring element. At the same time, the second body offers reliable guidance within the first body, so that there is sufficient stability when the handle is adjusted in the direction of the base section.

Provision can furthermore be made for the second body to be axially adjustable so as to be secured against rotation.

To this end, the invention provides in particular that at least one projection extends from the first body and engages in a recess, such as a slot or groove, running in the longitudinal direction of the hollow-cylindrical second body, or vice versa.

It should be emphasized in particular that the base section in the form of a pedestal has a base section, in particular made of metal, and a plate-like or hood-like cover covering this on the body side.

The bottom section itself can be made of heavy material, such as a metal plate, so that the holder has sufficient stability. In contrast, the other components can be made of plastic. In particular, injection-molded parts come into question, which can optionally be metallized.

Furthermore, the first body, in particular the intermediate wall, should preferably be connected to the bottom section by means of at least one screw element.

In particular, this makes it possible to easily transport the holder by grasping the handle.

According to the invention, the invention provides that an enveloping end extends from the base section along the first body into the area of the second element, such as the handle, or surrounds the base section, with the enveloping section having a longitudinal slot extending over its entire height is formed in particular by overlapping and mutually spaced longitudinal edge sections of the envelope.

To fix the casing, there is the possibility that the cover of the base section protrudes peripherally over the base section at least in sections and that the protrusion formed in this way is underlaid by at least one, in particular web-like or flange-like, inner section that protrudes radially from the inside of the casing.

Alternatively, it is provided that between the base section and the cover there is a circumferential recess, such as an annular recess, into which an inner section, in particular a web or flange-like, protruding from the inside of the casing, such as an annular web, engages.

Further details, advantages and features of the invention result not only from the claims, the features to be taken from them - individually and/or in combination - but also from the following description of the preferred exemplary embodiments to be taken from the drawing.

In the figures, in which basically the same elements are provided with the same reference numbers, embodiments of roller mounts and these surrounding envelope shown, based on which the teaching of the invention is explained.

The roll holders according to the invention are used to hold flat materials wound on a sleeve, such as paper, preferably paper kitchen towels, plastic foils, metal foils, such as aluminum foils, and to create the possibility of removing a desired section from the roll without the roll continuing to rotate.

Main components of the Figures 1 to 8 The kitchen holder 10 to be removed are a base plate 12 referred to as the base section - also referred to as a base or base element -, a sleeve 14 referred to as a hollow-cylindrical first body, a rod element such as a threaded rod 16 referred to as the first element, and a handle 18 referred to as the second element, which have different configurations can, as the figure. Clarify self-explanatory. However, it is essential that the handle 18 has, at least in sections, a conically tapering underside 22 in the direction of the opening 20 of the sleeve 14 Sleeve 14 interacts in the edge area on the opening side in such a way that the sleeve 14 expands circumferentially with the result that an inner tube surrounding the sleeve 14, for example a kitchen roll, is subjected to a force and can therefore no longer be rotated around the sleeve 14.

A construction with the same effect is obtained when a handle is connected to an element whose underside has the previously mentioned geometry (conical at least in sections). In this respect, the solutions are to be seen as equivalent.

The second element designed as the handle 18 does not necessarily have to have a cone or cone or truncated cone shape on the underside. Other geometries are also covered by the invention, provided it is ensured that when the handle 18 is moved in the direction of the base 12, the opening 20 of the sleeve 14, ie the first body, is spread open.

The sleeve 14 is slotted starting from the opening 20 . Preferably, for example three or four corresponding longitudinal slots 24 are provided, extending from the opening 20 over a length which is preferably about 1/3 to 2/3, more preferably about half of the sleeve 14. This opens up the possibility of using rollers of different lengths in the holder 10 .

From the graphic representation of 1 It is also clear that the sleeve 14 is widened in the shape of a tulip in the area of the opening 20, so that it is possible to slide along the underside 22 of the handle 18, which has a cone or truncated shape at least in sections, preferably overall, when the latter is adjusted in the direction of the base plate 12 becomes.

In 8 a slot 26 can be seen. The tulip-shaped opening area is also shown. The arrows 28, 30 are intended to indicate that when the handle 18, designed as a handle in the exemplary embodiment, is pressed into the sleeve 14 in the direction of the arrow 32, the sections 34, 36 delimited by the slots 24, 26 are bent apart and thus the sleeve 14 is expanded circumferentially.

The sleeve 14 has in its area running on the bottom side, ie on the base side, an intermediate wall 38 through which the rod element--called threaded rod 16--is penetrated. The threaded rod 16 has a cap 42 in its end region 40 which is preferably designed as a cap nut with a collar 62 . The collar 62 has an outer diameter that is larger than the opening in the intermediate wall 38 through which the threaded rod 16 passes. Thus, the partition and the cap 42 limit the movement of the threaded rod 16 and thus of the handle 18 away from the base 12 .

Above the intermediate wall 28, the threaded rod 16 is surrounded by a spring element--a coil spring 44 in the exemplary embodiment. The intermediate wall 38 forms a first stop against which the helical spring 44 can be pressed.

Oppositely, the coil spring 44 is fixed between a welded counterpart 46 extending from the threaded rod 16 and a washer 48 secured by a nut 50 screwed onto the threaded rod. By tightening the nut 40, the coil spring 44 is thus fixed between the counterpart 46 and the washer 48.

As can be seen from the drawings, the handle 18 merges with its conically tapering underside 22 into a further sleeve 15, which is guided within the first body, i.e. the sleeve 14, outside the area of the latter in which the slots 24 get lost. The additional sleeve body 15 surrounds the threaded rod 16 coaxially, as a result of which axial guidance occurs when this is adjusted.

The other sleeve 15 has a bottom wall 17 at its other end, which runs between the washer 48 and the counterpart 46, as can be seen in the figures in a self-explanatory manner.

The coil spring 44 forces the threaded rod 16 and thus the handle 18 connected thereto away from the base plate 12 , provided that a force in the direction of the base plate 12 does not act on the handle 18 .

In this state, which in 3 is shown again, in which the application of force away from the base plate 12 is symbolized by the arrow 52, a kitchen roll 54 surrounding the sleeve 14 can be rotated freely, although there is a certain inhibition due to the outwardly inclined end sections 56 of the sleeve 14 in the opening area can.

The operation of the intermediate wall 38 and the counterpart 46 with the washer 48 and the nut 50 and thereby enabling effect of the coil spring 44 is again from the figure 5 and 6 self-explanatory recognizable.

In order to limit a movement of the threaded rod 16 in the direction of the base 12, a stop 58 can emanate from the threaded rod 16, which abuts on the side 60 of the intermediate wall 38 facing away from the base when a force opposing that of the coil spring 44 acts on the handle 18. Another axial Adjusting is therefore impossible. The dividing wall 38 thus defines the stroke, which is consequently limited by the stop 58 on the one hand and by the collar or flange 62 of the cap nut 42 on the other hand when they come into contact with the underside 64 or the top 65 of the dividing wall.

Alternatively, the lifting movement in the direction of the base 12 is limited by the interaction of the threaded rod with a pressing element 200 when this rests against the bottom wall 248 of the base 12, as in connection with the explanations relating to FIG Figures 12 to 28 becomes recognizable.

Instead of the cap nut 42, a screw sleeve 342 can also be provided, as can be seen from FIG 29 results.

In figure 5 shows the maximum stroke of the threaded rod 16 in the direction of the base plate 12, which corresponds to a maximum expansion of the sleeve 14.

In 6 shows the state in which the force on the handle 18 is loosened or released, so that the action of the spring 44 causes the threaded rod 16 to move in the direction of the arrow 66 until the collar or flange 62 rests on the underside 64 the intermediate wall 38 is applied. This situation is in the 1 and 2 played back. It can also be seen that the underside 22 of the handle 18 runs at a distance from the sleeve 14, ie the sections 56 bent away outwards.

In 2 For example, the roller mount 10 is further surrounded by a wrap 68 that extends from and is fixed to the footplate 12, as will be described below.

In the figure 5 and 6 one can also see that the sleeve 14 is connected to the base plate 12 via the intermediate wall 38 . Several screws 70 are provided for this purpose. Thus, the base plate 12 forms a portable unit with the sleeve 14, with the result that the roller holder 10 can be transported when the handle 18, which is designed as a handle in the exemplary embodiment, is grasped.

In the base plate 12, also called the base, a recess 13 is provided in the axial extension of the threaded rod 16, into which the end of the threaded rod 16 with the cap nut 42 can immerse.

is in 3 shown the position in which the roller 54 can be rotated, the clarifies the 4 the position in which the kitchen roll is locked. In this case, the handle 18 is pressed in the direction of the base plate 12 against the spring force (arrow 72), so that the outwardly bent sections 56 of the sleeve 14 interact with the conical or truncated cone-shaped underside 22 of the handle 18 and are pressed outward with the result that the sections 56 bear against the sleeve 73 of the kitchen roll 54 in such a way that rotation is prevented by frictional engagement.

The 7 shows the state in which the kitchen roll 54 is pushed onto the roll holder 10 . The outwardly sloping sections 56 are pressed together (arrows 86, 88) so that the kitchen roll can be slid over the sleeve 14 in the direction of arrows 90, 92.

It should be noted with regard to the base 12 that it consists of a floor section 74 running on the bottom side and made in particular of metal and a plate 76 covering it, which runs on the casing side, as the drawings make clear. In this case, the plate 76, which is made of plastic and has a metal look, such as the handle 18, can have, protrude peripherally over the plate-shaped bottom section 74, as is shown in FIGS figure 5 and 6 is indicated. This area is underlaid by an inwardly projecting web-shaped section 78 which runs in the bottom area of the casing 68 surrounding the roller mount 10, as a result of which the casing 68 is secured and fixed.

Alternatively, a slot-shaped circumferential recess can be provided between the base plate 74 and the cover 76, in which a corresponding section of the casing 68 engages.

As emerges from the 10 results, the envelope 68 may have a cylindrical shape surrounding the kitchen roll 54 peripherally. In order to be able to deduct paper, the envelope 68 has a slot 70 between the overlapping longitudinal edge regions of the Envelope 68 runs, which are spaced from each other. Also in this respect 10 self-explanatory.

In 11 a hollow cuboid envelope 82 is provided, which also serves as a wall mount. For this purpose, the enveloping end 82 has a bottom wall on which the base 12 is placed. On the back, the casing 82 has a longitudinal slot 84 through which fastening means such as screws can pass, in order to fasten the casing 82 to a wall, for example.

The longitudinal axis of the envelope 82 can be both horizontal and vertical.

9 shows an alternative embodiment of a roller mount 100, which has the same functions as the base section (foot plate) 12, the first hollow cylindrical body in the form of the sleeve 14, the first element in the form of the threaded rod 16 and the second element in the form of the handle 18 Exercise roller mount 10, so that reference is made to the relevant statements. The roller mount 100 also ensures that a roller receiving it can either be rotated or fixed. The latter is accomplished by expanding the circumference of sleeve 14 as has been described.

The roller mount 100 differs from the roller mount 10 in that the forces directed away from the base plate 12 on the threaded rod 16 and thus the handle 18 are not generated by a separate spring element, but rather by means of a spring 144 formed integrally with a further second hollow-cylindrical body 114 , Which is also supported on the intermediate wall 38 of the sleeve 14.

In order to prevent the second sleeve 114 from rotating when it is moved axially, an anti-rotation lock is provided, which in the exemplary embodiment is formed by a projection 102 extending from the inner wall of the sleeve 14, which engages in a longitudinal slot or in a longitudinal groove in the second sleeve 114 .

In the Figures 12 to 28 is a self-protection enjoying role holder 150 shown, the structure of the role holder 10, 100 according to the Figures 1 to 9 corresponds, but additionally has a pressure means 200 to be designated as a pressing means, which then when a section of a kitchen roll is severed or torn off is to be tilted in the direction of the kitchen roll to allow additional fixation of the kitchen roll. In this case, the pressure medium is designed such that deviating from the design of the roller mount according to Figures 1 to 9 , like these also in the Figures 12 to 25 is shown, a spreading of the sleeve 74 of the kitchen roll 54 receiving sleeve 14, which is designed as a hollow cylindrical receiving element, is not necessary, although this should preferably be the case.

In 12 is the basic structure of the role holder according to Figures 1 to 8 or. 9 shown so that according to the Figures 1 to 9 the same reference numbers are used for the same elements. In addition, a pressure means 200, which is referred to as a pressing element, can be adjusted translationally to the sleeve 14 or to the kitchen roll 54 held by the sleeve, ie radially adjustable in relation to the sleeve 14 in order to be able to exert the required pressure on the kitchen roll 54. The pressing element 200 can be displaced in a guided manner in a translatory manner in the base plate 12, with translatory not only including a straight line, but also an at least partially curved line, such as an arc.

The pressing element 200 has a first leg 202 and a second leg 204, which describe approximately a right angle to one another. The first leg 202 is aligned in the functional position such that it extends along the longitudinal axis of the sleeve 14 and the second leg 204 along a plane that is spanned by the base or the base plate 12, ie the base element. It is essential that the pressing element 200 can be tilted about a section 206 extending from the second leg 204 so that, depending on a constraining force acting on the second leg 204, it either runs tilted towards the kitchen roll 54 or tilted towards it, as can be seen from a comparison the 24 and 25 results. The tilt angle can be in the range between 5° and 10°, in particular approximately 7°, as in FIG 22 is shown.

The tilting can be accompanied by a rolling movement.

The first leg 202 has a frame 208 with an elongated opening 210 running in its longitudinal direction, within which a leaf spring element 212 formed integrally from the pressing element 200 can be adjusted, the upper The end 213 is not connected to the first leg 202, that is to say it can be pivoted relatively freely with respect to it, but can rest against a stop 216 facing away from the kitchen roll, so that movement is limited in the direction of the kitchen roll 54.

The second leg 204 has three supports, of which a first support 214 is formed by longitudinal edges 216 , 218 of side legs 220 , 222 of the second leg 204 . The longitudinal edges 216, 218 are lower longitudinal edges of the side legs 220, 222. Upper longitudinal edges 224, 226 of the side legs 220, 222 form a second support 228. Between the first and second supports 214, 228 runs a flat third support 230, which is approximately parallel , In particular parallel, can run to the first support 214, as can be seen in principle from the 27 should result.

The function of the first and second support 214, 228 is that when a constraining force is not exerted on the third support 230, the pressure medium or tear-off element 200 runs in such a way that the second support 228 rests on the underside 232 of the head wall 234 of the Base 12 runs or rests against this, as is self-explanatory from the 24 results. The positioning in the basic position, i.e. not being tilted, can be brought about due to the mass distribution between the first and second leg 202, 204 in relation to the tilting point (support 206) and/or by the leaf spring 212.

In this case, only the leaf spring element 212 acts on a roller held by the sleeve 14 , which is subjected to a force in the direction of the roller 54 in that the pressing element 200 is pulled in the direction of the sleeve 14 by means of a helical spring 236 .

The helical spring 236 acts on a leg element 238, which can be pivoted about an axis 240 running in the peripheral area of the base 12 and has a connecting link slot 242 designed as an elongated hole, into which a projection 244 protruding from the second leg 204 on the bottom side engages. The axis 240 runs perpendicular to the plane spanned by the base 12 .

Due to the force generated by the coil spring 236, the leg element 238 tends to be pivoted in the direction of the sleeve 14, with the result that due to the projection 244 of the pressing element 200 engaging in the link slot 242, this is pulled in the direction of the sleeve 14 or the kitchen roll 54 received by it, that is to say a force is applied.

In the 18 and 19 the pressing element 200 or the second leg 204 of this is shown in two positions, with in 18 the position with a full kitchen roll and in 19 which should be illustrated with an unrolled kitchen roll. It can also be seen that the second leg 204 is translationally adjustable within a guide formed in the base plate 12 .

According to the explanations of the Figures 1 to 9 the roller mount 10 has a threaded pin 16 which is subjected to a force directed away from the base 12 counter to a spring 44 . To overcome the spring force, the threaded rod 16 or a handle 18 connected to it must be adjusted in the direction of the base, i.e. the base element 12, whereby the pressing element 200 is tilted and the first leg 202, i.e. its frame 208, is pressed against the roller 54 becomes. The pressing element 200 can be pivoted or tilted to an extent until the first support 214 rests on the bottom surface 246 of the bottom wall 248 of the base element or base plate 12 . This is based on the 25 presented in a self-explanatory manner.

So that a secure fit and pressing is possible, the frame 208 has a type of concave geometry on the roller side, as can be seen from the figures.

In order to prevent the leaf spring 212 from getting in the way when the roll material is being pulled off, which rests against the pressing element 200 regardless of its position, the longitudinal edges 252, 254 are rounded off or chamfered.

The following should also be noted with regard to the individual figures.

The 12 it can be seen that the sleeve 14 is slotted in order to enable it to be spread open when the handle 18 and thus the threaded rod 16 are adjusted in the direction of the base against the force of the spring 44 in order to prevent a roller surrounding the sleeve 14 from rotating prevent. The kitchen holder according to 12 is in figure 13 displayed in a position rotated by 90°. The side view shows the pressure element 200 with the leaf spring 212.

In 14 is the reel mount 12 and 13 shown in a position in which a kitchen roll 54 is slipped onto it. In this case, the pressing element 200 is pressed outwards against the force produced by the helical spring 236 , as symbolized by the arrow 270 .

15 shows a section of the 14 . One can see the first leg 202 with the frame 208 and the leaf spring 212. By interacting with the lower edge of the roller 54, the pressing element 200 is pushed out to the left in the drawing.

Regardless of the position of the pressing element 200, the leaf spring 212 always rests against the outside of the kitchen roll 54, and regardless of its circumference.

It should be mentioned that, of course, another spring element can also be used instead of the leaf spring, in which case the required pressure application is also made possible without such an element and simply because the first leg 202 rests against the kitchen roll.

According to the top view 17 shows that the frame 208 has a concave geometry on the roll side and that the longitudinal edges 252, 554 of the leaf spring are rounded so that they cannot lead to an obstruction when the paper is pulled off the roll 54, ie when the roll is rotated.

20 shows a sectional view of the roller holder 150 with no pressure acting on the threaded rod 16, so that the second support 228 of the second leg 204 comes to rest on the inside 232 of the head wall 234 of the base 12. One can see the lower longitudinal edges 216, 218 of the side legs 220, 222 of the second leg 204, the intermediate wall running perpendicular to these and forming the third support 230, and the upper longitudinal edges 224, 226, which form the second support 228, as mentioned. The side walls 222 extend parallel to each other and in planes parallel to the longitudinal axis of the threaded pin 16.

In 21 the pressing element 200 is shown in its quasi outermost position, i.e. when the receiving element or the sleeve 16 is surrounded by a full kitchen roll 54 without the threaded rod 16 acting on the second leg 204, ie the third support 230.

In contrast, in 22 the threaded rod 16 is adjusted by a force (arrow 72) acting on the handle 18 such that the pressing element 200 is tilted in the direction of the roller 54 and the first support 214 rests on the bottom surface 246 of the bottom wall 248 of the base 12.

In the 23 and 24 are the positions of the pressing element 200 compared to the 21 and 22 reproduced in an enlarged representation, so that reference is made to the relevant explanations.

The depictions in the 23 , 25 differ in that in the former the pressing element 200 is tilted for tearing off a section on a full kitchen roll 54, whereas in 25 the kitchen roll 54 is largely unwound.

The 29 is a detail of a further embodiment of a roller mount can be seen, the basic structure and the mode of action of the Figures 1 to 11 or the the Figures 12 to 28 corresponds as far as the spreading of the sleeve 14 and the pressing of the pressing element 200 in its tilted position are concerned.

Is according to figure 5 the movement of the threaded rod 16 caused by the spring 44 is limited by the cap nut 42 or its collar by resting against the wall 38, the cap nut 42 can correspond to the 20 can also be replaced by lock nuts 340 screwed onto the threaded rod 16. To that extent 20 self-explanatory.

According to 29 a screw sleeve 342 is screwed onto the threaded rod 16, which extends over the end of the threaded rod 32 and with its free end to the Pressing element 200 or the third support 230 interacts to tilt the pressing element 200 .

The movement of the threaded rod is thus limited on the one hand by the upper edge 344 of the screw sleeve 342 in the drawing when this rests against the underside of the intermediate wall 38, and on the other hand when the lower edge 346 of the screw sleeve is supported on the third support 230 and the second leg 204 rests against the inside 246 of the bottom wall 248 of the base 12 .
