Abstract

The holder has an upper holding element (18) and a lower holding element (28) rotatably receiving a paper roll (12) such that the roll is rotated around a rotational axis (D) and paper is unwound from the roll by pulling a free end (16) of the paper wound on the roll. The holding elements clampingly act upon the roll in an axial direction and partially project into axial edge regions of the roll so that the roll is held by the holding elements. The holding elements move relative to each other and are connected with each other by a guide element, which is arranged outside the roll.

Description

The present invention relates to a paper roll holder for kitchen rolls or toilet paper rolls or the like with a holding arrangement which is adapted to receive the tubular roll rotatably, such that by pulling on the free end of the wound on the roll paper, the roll rotated about its axis of rotation and Paper can be unwound from the roll, wherein the holding arrangement comprises two the role in its intended arrangement in the holding arrangement receiving retaining elements which are interconnected by means of a guide element of the holding arrangement and movable relative to each other, wherein the holding elements are formed such that they in the respective axial edge regions of the intended purpose taken role at least partially protrude into the roll interior, so that the role is held by them alone, and wherein the guide elements connecting the holding elements outside the bestimmungsgemä ß recorded role is arranged.

Such a paper roll holder is for example from the US 4,762,288 known. Known paper roll holder for kitchen rolls of paper usually have a rod-like retaining element which is inserted through the roller and the ends of which are releasably secured to the housing with respect to the paper roll holder, so that when replacing a paper roll, the rod-like holding member removed and removed the empty paper roll and a new can be used. Such paper roll holders are known both for mounting on the wall and the hanging receiving the paper roll, as well as for installation on a substrate, such as kitchen worktop or the like., So that the paper roll is substantially vertical.

However, the known paper roll holders often have a fixed width or height, so that only certain types of paper rolls, which correspond approximately to the dimensions, in particular the length of the rod-shaped holding element, can be accommodated in the paper roll holder. Frequently, the known paper roll holder are also simply dimensioned for a maximum paper roll length, smaller paper rolls can also be recorded. Further, changing paper rolls in such paper roll holders is rather cumbersome, since the rod-shaped holding element must first be removed from the paper roll holder, the old empty paper roll has to be removed and a new one has to be placed on the holding bar.

The object of the invention is to provide a paper roll holder which avoids the abovementioned disadvantages, in particular allows adaptability to paper roll sizes or widths.

To solve this problem, a paper roll holder is proposed in which the holding elements can be brought or brought by utilizing the force of gravity and / or by applying a biasing force in a clamping in the axial direction with the roller.

Due to the clamping action on the roller by the retaining elements, no retaining rod passing through the roller is required, so that the replacement of paper rolls is simplified. In this case, the relative mobility of the two holding elements relative to each other allows a simple removal of the clamping action by manual action of a user, so that the role simply removed and a new role just as easily can be used again, the two holding elements can be brought into clamping engagement again. This role change can in particular be carried out with one hand, wherein the roller is grasped with one hand and pressed in the direction of a holding element for the purpose of moving apart of the two holding elements. The two holding elements are in particular by the guide element telescopically with each other connected, wherein the guide element is arranged outside of the intended purpose recorded role, so that the holding elements are movable in particular in the axial direction to each other.

The clamping action of the roller by means of gravity comes into question in particular in the case of a paper roll holder which is arranged on a substrate and the roll is received standing in it so that the axis of rotation runs essentially vertically. In such a clamping action by utilizing gravity, if necessary, a gravity-assisting spring may be provided, so that the paper roll is securely held in the paper roll holder during the unwinding of paper. On such a spring support but can also be dispensed with depending on the configuration of the holding elements and the guide element and appropriate choice of material, since the forces acting on the basis of the weight of the holding element and guide elements sufficient to keep the roll of paper safely. In an example attached to a wall paper roll holder, in which the axis of rotation of the paper roll is substantially horizontal, is for clamping application applied by spring force biasing force acting between the two holding elements, imperative because in such a case no clamping action due to gravity is caused.

The holding elements are preferably connected to the guide element by means of a respective spacer.

Preferably, in a paper roll holder for the upright recording of the paper roll of the one, lower spacers designed as part of a stand of the paper roll holder, such that the role between the base and the upper spacer is receivable or received standing. In such an embodiment, the base simultaneously forms the lower spacer, so that the structure of the paper roll holder is simplified.

The roller-facing top of the stand preferably has a step, such that the roller rests only partially with its axial, in particular lower edge on the top of the stand, preferably with about half of its axial edge. The support of the roller with its axial edge on a part of the top of the stand allows a braking effect by friction of the roller on the top of the stand, so that when unrolling paper there is no risk that a small paper length is unrolled by low applied tensile forces. In particular, it is proposed that the step be dimensioned and designed such that tensile forces acting on the paper at the free end result in unrolling a sheet of paper and almost automatic tearing off of this sheet along the perforation provided in such paper rolls. The step formed in the top of the stand is also very conducive to the clean and complete tearing off of a paper sheet from the roll along the perforation, since the paper to be torn off can be kept inclined relative to the base, as between the paper to be torn off and the base due to the step a gap is created which facilitates the complete tearing along the perforation. In that regard, the stage is also a kind of fracture edge, over which the lower edge of the paper can be bent and thus separated cleanly along the perforation. In known paper roll holders containing a roll of paper, the entire axial end surface of the paper roll is usually on a stand, so that the tearing of a sheet along the perforation is hindered, especially in the last few centimeters of tearing, resulting in particular to cracks, which do not run along the intended perforation, but damage the paper sheet to be torn off or tear out a piece of paper from a subsequent paper sheet.

Preferably, the upper spacer of the base forming the lower spacer and the upper spacer are configured such that they lie in planes substantially orthogonal to the guide element. The two spacers and the guide element thus form a kind of rectangular Recording in which the role can be introduced.

The guide member is preferably formed of two telescopically nested rods, preferably one, lower rod is fixedly connected to the base and the other, upper rod is telescopically inserted into the lower rod, such that it relative to the lower rod and the base is mobile. In such a telescopic design, the weight of the upper rod also acts as a force component on the einzklemmende role due to gravity, so that a better clamping action can be achieved by gravity through the telescopically movable rods. Further education can be provided between the two rods effective anti-rotation, which allows the telescopic movement. In this case, the rotation can be designed such that it serves as a stop or limit the vertical movement of the upper rod.

Preferably, the upper spacer is attached to the upper rod with the upper support member such that the upper rod, the upper spacer and the upper support member are moveable relative to the lower rod together.

The lower holding elements is preferably attached to the base. The two holding elements can be screwed, glued or connected in any other suitable manner with their respective spacer element, so the upper spacer or the base. Conceivable, of course, also mutual locking or the like.

The axis of rotation of the roller and the guide element are preferably arranged so that they are substantially parallel to each other.

Further, it is proposed that the holding arrangement is designed such that the guide element is inclined relative to a vertical axis with respect to the ground, in particular by about 1 ° to 10 °, preferably about 4 ° to 6 °. Such an arrangement of the guide element leads to a tilting of the guide element and thus also arranged paper roll, which simplifies the tearing of a sheet of paper, since the tilting is provided such that the tilted roller has its lowest point in the region of the guide member, so that in a lateral area, in which the tearing off of a paper sheet will take place, there will be a greater distance to the ground, so that the tearing off can take place unhindered.

As an alternative to the parallel arrangement of the axis of rotation of the roller and the guide element is proposed with an inclined guide element, that the holding elements are arranged such that between the axis of rotation of the purpose recorded roll and the guide element an angle of less than 10 °, preferably less than 5 ° is formed in particular such that, with the guide element inclined, the axis of rotation is inclined by about 1 ° to 3 ° in the same direction as the guide element relative to the vertical. Such an arrangement means that the roller with its axial edge no longer fully rests on the upper side of the base, but that the required frictional forces are present substantially at the upper edge of the step formed in the base. Furthermore, this arrangement of the paper roll relative to the guide element and the top of the stand has the effect that the free end is not unwound by the forces acting in the range of the level of the stand over this edge away from the role, but is held by this upper step edge. This, in turn, causes the top of the free end to be radially and along a short perimeter area away from the paper roll, so that this top area can be easily gripped by a user and used to unroll the next sheet of paper demolish.

When inclined guide member is proposed that the top of the stand is inclined at substantially the same angle relative to the horizontal surface as the guide element, so that the guide element and the top of the stand are oriented substantially orthogonal to each other.

The holding elements, which act on the roller by clamping and at least partially introduced in the axial direction in this, are preferably formed frustoconical. Such a frustoconical configuration simplifies the insertion of the roller and leads to a forced centering thereof between the two holding elements. The upper holding element is preferably designed so that the axial inner edge of the roller rests against the inclined frustoconical surface, so that there is a free space between the axial upper side of the roller and the upper spacer element. The lower holding element, which is preferably attached to the base, is preferably configured such that it completely penetrates into the roller in the axial direction, so that the roller with its lower axial edge on the top of the stand or on the upper edge of the stand provided level can rest.

Fig. 1 shows a schematic perspective view of a paper roll holder 10 with recorded therein kitchen roll paper 12. The paper roll holder 10 is an example of standing on a not shown pad or the like. Holder with a stand 14. The kitchen roll paper 12 is vertically received in the paper roll holder 10, wherein a free end 16 of the kitchen roll paper protrudes slightly in the radial direction along the roll circumference, so that the free end can be easily grasped by a user. From the Fig. 1b ), a front view according to the arrow Ib) of Fig. 1a ), a rotation axis D of the kitchen paper roll 12 can be seen, around which the paper roll 12 is unrolled when gripping and pulling on the free end 16. From the representation of Fig. 1b ) is also seen that the roller 12 between the base 14 and an upper support member 18 is received by clamping.

The upper support member 18 is attached to a spacer 20 which extends in the radial direction from the axis of rotation D beyond the radius of the roller 12 and with a rod-like guide member 22 (see Fig. 1a )) connected is. The spacer 20 is also in the plan view according to Fig. 1c ) can be seen. The base 14 has an oval Base on, through the center of the axis of rotation D of the roller 12 extends. Of course, the base can also have a different base shape.

Fig. 2 shows a schematic and exploded perspective view of the paper roll holder 10 of Fig. 1 , From this representation it can be seen that the base 14 has a top 24 in which a step 26 is provided. This results in an upper surface 24 'and a lower surface 24 ".A lower support element 28 is provided in the center of the pedestal 14, the underside of which is designed correspondingly to the surface course of the pedestal 14. This lower support element 28 is inside the paper roll arranged as intended The pedestal 14 is preferably made of metal and has on its underside a slip-resistant element 30, for example a rubber or silicone mat or the like in an edge region of the pedestal 14, an opening 32 is provided into which a lower bar 34 of the guide element 22 can be inserted or inserted, and an upper bar 36 is telescopically and longitudinally displaceably inserted into the lower bar 34, the spacer 20 being at the upper end of this bar 36 with the upper stop element 18 is attached. Thus, the upper rod 36, the spacer 20 and the upper support member 18 are displaceable relative to the lower rod 34 and the base 14 in the vertical direction V together. In the lower end of the upper rod 36, a closure member 38 is inserted, which comes when pulling the upper rod 36 in the vertical upward direction of a rod 40 inserted into the lower rod 34 into abutment, so that this vertical movement is limited upwards.

Fig. 3 shows a sectional view corresponding to the section line III-III of Fig. 1B , From this representation it can be seen that the paper roll 12 used as intended rests with its lower edge on the upper surface 24 'of the upper side 24 of the base 14, so that when pulling on the free End 16 due to the frictional forces between roller and upper surface 24 'a braking effect is generated. As already indicated, the lower holding element 28 extends in the axial direction into the roller 12 and guides the roller 12 in the radial direction. At its upper end, the inner circumference of the roller 12 is guided by the upper holding element 18 in the radial direction, wherein the inner circumference rests against the inclined outer surface of the upper holding element 18. This has the advantage that the roller with its upper edge does not come into contact with the spacer element 20. It can also be seen from this illustration that the upper rod 36 is inserted telescopically into the lower rod 34 of the guide member 22, the upper rod 36 being closed by the closure member 38 at the bottom. The pin 40, which is connected to the lower rod 34, allows the vertical movement of the rod 36 relative to the rod 34, since the upper rod 36 includes in its lower portion longitudinal slots 42 which can receive the pin 40 ( Fig. 5 ). The pin 40 also acts as anti-rotation, so that the upper rod 36 is not rotated relative to the lower rod 34, but can be adjusted in the vertical direction.

For inserting or replacing a paper roll 12, the upper rod 36, the spacer 20 and the holding member 18 relative to the lower rod 34 are pulled vertically upwards, so that the distance between the two holding elements 18 and 28 is increased. After inserting a roll 12, possibly after previously removing the leftover cardboard inner roll of such a paper roll, the rod 36, the spacer 20 and the holding member 18 can be lowered again until the upper support member 18 on the radially inner edge of the roll used 12th rests. Due to the weight of the rod 36, the spacer 20 and the support member 18 is due to gravity, a clamping of the paper roll 12 between the two holding elements 18 and 28. Since the guide member 22 and the said rods 34 and 36 and preferably also the spacer 20 made of metal, especially stainless steel, these parts have a relatively high weight so that sufficiently high forces due to gravity act, which counteract the tensile forces when unrolling paper from the roll 12, so that the roll 12 can not be pulled out of the holder.

Like from the Fig. 3 As can be seen, the axis of rotation D of the roller 12 is substantially parallel to the longitudinal axis L of the guide member 22 and the rods 34 and 36, respectively. It should also be noted that the step 26 formed in the top 24 of the pedestal 14 is a clean and complete tear of a paper sheet along the usual in such rolls of paper perforations possible, since the slightly sloping down tearing paper with its lower edge does not stand on the lower surface 24 "of the base 14 and thus the tearing process along the perforation is not affected.

In the Fig. 4a ) and b), the upper holding member 18 and the lower holding member 28 are shown enlarged. Both have an opening 19 and 29, in which a barrier can be screwed for connection to the spacer element 20 or base 14. The two holding elements 18, 28 are designed conical, with their inclined peripheral surfaces 21 and 31 have different inclinations. In particular, the circumferential surface 21 of the upper holding element 18 is inclined such that a roller used in the roll holder 10 rests with its inner peripheral edge on the inclined surface 21.

As already indicated above, the shows Fig. 5 in the sub-figures a) and b), the upper rod 36, which has two longitudinal slots 42 in its lower region, which lie opposite each other in the radial direction. Furthermore, the rod 36 has two openings 44 arranged orthogonally to the slots 42, into which nubs 46 formed on the closure element 38 can engage radially ( Fig. 6a ) / B)). The closure element 38 itself has two slot-like openings 48, which are aligned in the inserted state in the rod 36 with the slots 42. The lower edge 50 of the slot-like openings 48 limited in the inserted state of the rod 36 whose vertical Moving upwards, as this lower edge 50 comes into abutment with the pin 40 which extends through the lower rod 34 ( Fig. 3 ).

Fig. 7 shows in a partial side sectional view of a second embodiment of the paper roll holder, wherein the longitudinal axis L of the guide member 22 relative to the vertical V is inclined by an angle α, which is preferably about 1 to 10 °, in particular about 4 to 6 °. The longitudinal axis L substantially orthogonal top 24 of the base 14 is thus inclined by approximately the same angle α 'in the same direction. The two holding elements 28 and 18 are compared to the first embodiment slightly offset from each other, so that between the rotation axis D and the longitudinal axis L of the guide member 22, an angle β of preferably less than 5 ° is formed. In this case, the axis of rotation D is inclined by a slightly smaller angle y, which is about 1 to 3 °, in the same direction as the longitudinal axis L. In such an inclined arrangement, the lower axial edge of the roller 12 is slightly larger than the upper surface 24 '. of the stand 14 is raised so that it is no longer in full-surface contact. However, the tilting of the roller leads to greater pressure on the upper edge 47 of the step 26, so that the required braking effect when unrolling paper is also given. With such an arrangement of the paper roll 12 in the holder 10, the abutment of the lower edge of the paper roll in the region of the edge 47 prevents an automatic unwinding of the free end 16 of the roll, since the lower edge of the free end paper sheet does not over this edge 47 away in the direction of the guide member 22 is automatically movable. Further, the inclination of the retainer assembly as a whole and the roller lead to better angular ratios with respect to the clean tearing of individual sheets of paper along the perforations already mentioned above, so that a clean tearing of individual paper sheets from the roll can be ensured.

It should be added that the embodiments shown for both preferred gravitational clamping action on the intended purpose recorded role could be supported for example by a provided in the rods 34 and 36 tension spring. Furthermore, a spring-loaded paper roll holder can be designed not only as a stationary paper roll holder, but also as a hanging, in which the axis of rotation of the roll would be substantially horizontal.

The presented paper roll holder allows by the longitudinal adjustability of the two holding elements 18 and 28 to each other the recording of different height paper rolls, so that roles of different manufacturers in one and the same paper roll holder can be easily absorbed. The adjustability is about 3-10 cm. Of course, the paper roll holder shown here for kitchen paper can also be adapted in its dimensions, so that it can be used, for example, for about half the size of toilet paper rolls or the like. In addition to the free installation of such a paper roll holder on an anti-slip element, it is also conceivable that the base 14 is firmly connected, for example, with the ground, so that the paper roll holder remains at a certain location.
