Abstract
A holder (10) for at least two lavatory-paper rolls positioned one above the other and consisting of a paper web wound up on a sleeve or a shaft, the holder having a first and a second wall which are arranged in parallel at a distance to one other, wherein each of the walls has a guide for receiving one end of the shaft or of a shaft journal that can be received in an opening in the sleeve. The guide has a feed portion running vertically, the feed portion merging into an unrolling portion running at an inclination with respect to the vertical towards at least one first tear-off element or a stop, wherein the gravitational force of the lower roll located in the unrolling portion causes the circumference of the roll to lie against the stop and the paper web can be unrolled through a removal opening.
Description
- The invention relates to a holder for at least two toilet-paper rolls arranged one on top of the other, which consist of a paper web wound onto a sleeve or shaft, comprising a first and a second wall, which are arranged a distance apart from each other, whereby each of the walls comprises one guide for accommodating one respective end of the shaft or one respective shaft journal that can be inserted in the opening of the sleeve, whereby for feeding a toilet-paper roll the guide comprises a substantially vertically extending feed section, which changes into an unrolling section, which extends inclined to the vertical towards at least one first tear-off element or limit stop, whereby gravity forces the circumferential surface of the lower toilet-paper roll situated in the unrolling section to be in contact with the limit stop, and whereby the paper web can be unrolled from the toilet-paper roll though a dispensing opening and can be tom off at the at least one tear-off element.
- A holder for toilet-paper rolls of the above-mentioned type is disclosed in CH 571 994 B. This holder comprises first holding means, to maintain a first toilet-paper roll in a dispensing position, in which a user may withdraw a section of the material web, and to move the journals from a first position, in which
- the roll is full, to a second position, in which the roll is at least substantially used up. Further provided are second holding means, to releasably hold at least one second roll in the spare position above the dispensing position, whereby the first and the second holding means are coupled to each other via at least one pivotable lever, which in the first holding means interacts with the journals in the first roll, in order to respond to the latter's position, in order to hold the second roll in the spare position for as long as the journals of the first roll are moving from the first to the second position, and to automatically release the second roll from the spare position when the journals have reached the second position. Finally provided is a guide device, to guide the second roll from the spare position to the dispensing position once the lever has released the second roll. To ensure that the roll is only inserted into the dispensing device with a particular orientation, it is intended that the journals possess different diameters and that the guide channels possess different widths.
- In this embodiment as well, a circumferential surface of the paper roll bears upon a front wall that contains the tear-off edge, so that unrolling is only possible in one direction.
- DE 2 205 186 A describes a further holder for toilet-paper rolls. The holder consists of a base plate, on which a hood is mounted securable and lockable. From the base plate originate two walls, which are arranged in parallel at some distance from each other. Each of the walls comprises one guide for accommodating the respective end of a shaft that is carrying the paper roll, or for accommodating one of the shaft journals that can be accepted in an opening of a sleeve.
- The guide comprises an unrolling section that extends obliquely into the direction towards a withdrawal device, whereby the circumference of a toilet-paper roll presently in use bears upon ribbons of the withdrawal device. In this embodiment known in the art, the withdrawal device is embodied as an automatic device for unrolling and dispensing the paper that is wound onto the rolls. In addition, the guide comprises a feed section, which accommodates a toilet-paper roll as a spare and which extends substantially vertically and changes into the unrolling section.
- In this embodiment known in the art, the shaft is guided in slots of two laterally mounted metal sheets, which are attached to the base plate. The guides are open at their upper ends, so that the shafts with the toilet-paper rolls can be inserted from above. A pivotable lever is used to direct a toilet-paper roll that serves as a spare roll and is located in the upper area of the slots to be subsequently transferred into the oblique area of the guides, once the roll that that occupied this position earlier has been consumed and the empty sleeve has been ejected downward. The automatic device for unrolling and dispensing the paper wound onto rolls is susceptible to malfunctions. Furthermore, it is necessary to insert the toilet-paper rolls always with the same specified orientation to facilitate an automatic unrolling.
- DE 10 2011 004 511 A1 discloses a holder for toilet-paper rolls that comprises two lateral side elements that are connected via a front wall. In this, the front wall also forms a lower tear-off edge. In each of the side elements is provided a guide to accommodate one respective end of a shaft carrying a toilet-paper roll. The guides comprise a main section that extends approximately in a straight line towards the tear-off edge of the front wall. In order for a proper tear-off edge to be available irrespective of the diameter of the toilet-paper roll, biasing means are provided that shifts the toilet-paper roll in the direction towards the tear-off edge. The biasing means are embodied as a pivotably mounted arm, which due to spring-loading bears upon the ends of the shaft carrying the toilet-paper roll. This embodiment is structurally complicated and consequently susceptible to malfunction. By means of the biasing means, the circumferential surface of the toilet-paper roll is pressed against the inner surface of the front wall, so that it can only be unwound in one direction.
- U.S. Pat. No. 3,572,602 B relates to a dispenser of paper rolls. In this dispenser two paper rolls are arranged on top of each other within a holder, whereby when a lower paper roll has been used up, an upper, spare roll will be supplied via a guide. The end of a lever element, which is mounted rotatable about a journal, engages into the guide. The end of the lever serves to prevent the lower paper roll from being pushed back.
- US 2011/0095127 A1 relates to a holder for at least two toilet-paper rolls arranged one on top of the other, which consist of a paper web wound onto a shaft. Each of the shaft ends is supported in a guide, which are accommodated in opposing walls. In order to prevent a spare roll from sliding into the guide track, a retaining element is provided and can be actuated by a sensor element. When the diameter of the paper roll is large, the sensor element keeps the retaining element in a closed position, but switches it to an open position once the diameter of the paper roll falls below a minimum threshold diameter.
- WO 2008/004920 A1 describes a paper roll dispenser. The paper rolls are supported on a shaft with shaft ends, whereby the shaft ends are guided in lateral guides arranged in the wall elements. Integrated in the lateral guides is a spring-biased folding mechanism, which in a first state, i.e. when two rolls are present in the holder, extends in a plane parallel to that of the lateral wall, and in a second state, i.e. when no spare role is present in the guide, extends from the plane spanned by the wall element at an angle and blocks the guide channel.
- Based on this prior art background, it is the objective of the present invention to further develop a holder of the above-mentioned type for toilet-paper rolls in such a way that the holder possesses a structurally simple design, requires little maintenance, and is operationally reliable.
- One of the features of the invention that greatly aids meeting this objective is a holder comprising a locking element, which prevents the lower toilet-paper roll that is in use from being pushed back into the feed section. The locking element preferably is arranged in the guide.
- This ensures that the spare toilet paper roll can be held securely in the desired spare section of the guide, even if the lower toilet paper roll is pushed upwards as a result of improper use.
- The locking element is embodied as a sliding element, which is mounted slideably transverse relative to the guide in the second guide element, namely in the unrolling section extending inclined to the vertical.
- One end of the sliding element preferably bears upon an inner surface of the first guide element as a result of gravity or spring bias.
- The end of the sliding element protruding into the guide preferably is embodied wedge-shaped on the infeed side and possesses an oblique surface, so that the sliding element can be pushed into an open position by the shaft end or the shaft journal while the toilet-paper roll passes by, and after the shaft end or shaft journal has passed will be forced into a closed position by either gravity or spring bias.
- Further details, advantages, and features of the invention are not only described in the claims and the characteristic features specified therein—individually and/or in combination—but also in the following description of a preferred embodiment example shown in the figures.

FIG. 7 shows a front view of the wall with the guide for accommodating a shaft end or a shaft journal, and -
FIG. 8 shows a front view of the opened toilet-paper roll holder with two toilet-paper rolls arranged on top of each other. -
FIG. 1 shows in a front view aholder 10 for at least two toilet-paper rolls housing 16 with arear wall 18 for mounting theholder 10 on a wall. Pivotably mounted by means of a hinge 22 at therear wall 18 is adomed cover 20 that is lockable by means of afastener 24. Provided in a front side of thedomed cover 20 is aviewing port 26, through which the consumption of toilet paper of the toilet-paper roll 14 in use may be assessed. - The
holder 10 comprises a firstposterior wall 28 which extends in parallel to therear wall 18 and is connected with the latter. Arranged in parallel and at some distance to the firstposterior wall 28 is a secondanterior wall 30, whereby the toilet-paper rolls walls rotational axis 32, 34 extends perpendicular to therear wall 18. As a result of this, the toilet-paper rolls rotate in a plane that is parallel to therear wall 18, so that theholder 10 can be built with a low depth when using toilet-paper rolls of large diameter. - On the respective
inner sides walls respective guides shaft journals 44, 46, which protrude in the axial direction beyond the ends of the toilet-paper rolls 12, 14. Theshaft journals 44, 46 are end sections of acap sleeve paper roll paper roll - The usually
unperforated paper web 56 of the toilet-paper roll 14 in use is withdrawn from a withdrawal opening 58 on the bottom side and can be severed at the desired length by means of a first and a second tear-offelement elements first wall 28 and thesecond wall 30 and extend perpendicular to therear wall 18. -
FIG. 3 shows a lateral view of the holder with thehousing 16 in its closed state. -
FIG. 4 shows in a sectional view along the section line B-B ofFIG. 3 a front view of the first,posterior wall 28 with theguide 40. The second, posterior wall with theguide 42 is embodied accordingly as a mirror image and consequently is not explained in more detail. - The
guide 40 is embodied on a surface of theinner side 36 of thewall 28 and laterally is bordered by afirst guide element 64 and asecond guide element 66. Theguide 40 comprises several sections. Originating from theupper end second guide elements first section 40 a as a reserve section for accommodating the toilet-paper roll 12 as a spare. Thefirst section 40 a is followed by an adjacentsecond section 40 b, which extends vertically top to bottom and forms a feed section, to guide the toilet-paper roll 12 into a position, where it will be available for use by a user. - The
second section 40 b merges into athird section 40 c, which extends obliquely and straight towards the second tear-off edge 62. Consequently, thethird section 40 c forms an unrolling section, which serves to move the toilet-paper roll 14 in use by means of its own weight towards thelateral limit stop 72, whereby the circumferential surface of the toilet-paper roll 14 in use comes into contact with asurface 73 of thelimit stop 72. - The
third section 40 c merges into afourth section 40 d, which forms a vertical ejection section extending from top to bottom, to eject theempty sleeve 54 when the toilet-paper roll 15 in use has been consumed. - The ejection section is followed by a
fifth section 40 e, which extends obliquely in the direction towards the first tear-off edge 60 and forms a discharge section, that is embodied to discharge theempty sleeve 54. - Finally, the
guide 40 comprises asixth section 40 f, which extends obliquely upward and forms a removal section that allows lateral removal of theempty sleeve 54 from theguide 40. - If an empty sleeve is present at the lowest point of the
discharge section 40 c, then the preferably colour-highlightedstuds - The
discharge section 40 e is bordered in the direction towards the withdrawal opening 58 by thesecond guide element 66. As upper limit is provided athird guide element 74, which is arranged on thesurface 32 of thewall 28 at some distance above thesecond guide element 58. - The
first guide element 64 is embodied as a pivotable lever, which is mounted pivotable around ahinge 76 arranged in the transition region between thefeed section 40 b and the unrollingsection 40 c. Thepivotable lever 64 comprises a first arm 78, which together with an obliquely extendinglateral surface 80 forms a border of thereserve section 40 a and together with a straightlateral surface 82 forms a lateral border of thefeed section 40 b. - Provided in a transition region between the oblique
lateral surface 80 and the straightlateral surface 82 is aprojection 84, which may be positioned against alateral surface 86 of thesecond guide element 66 to block thefeed section 40 b. - Further, the
pivotable lever 64 comprises asecond arm 88, which extends from thehinge 76 towards the vertically extendingejection section 40 d, and ends at the level of thelimit stop 72. Alateral surface 40 of thesecond arm 88 forms a lateral lower limit of the unrollingsection 40 c, on which rests the journal 44 of the toilet-paper roll 14 in use, so that the first arm 78 of thepivotable lever 64 together with theprojection 84 is pressed against thelateral surface 86 of thesecond guide element 66, in order to prevent the toilet-paper roll 12 that is blocked in thereserve section 40 a from moving into thefeed section 40 b and consequently into the unrollingsection 40 c. -
FIG. 5 shows a front view of the holder in a sectional view along the section line C-C ofFIG. 3 , whereby the toilet-paper roll 11 serving as the spare is blocked in thereserve section 40 a by theprojection 84 of the first arm 78, and whereby the toilet-paper roll 14 in use with its journal 44 is situated in the unrollingsection 40 c, while the toilet-paper roll 14 along its circumference is in contact with thelimit stop 72, and thepaper web 56 emerges from thelower dispensing opening 58. - Because of the dead weight of the toilet-paper roll, a force acts upon the
second arm 88 of thepivotable lever 64 in such a way that the first arm 78 with theprojection 84 is pushed against theinner surface 86 of thesecond guide element 66, so that the toilet-paper roll 12 intended as the spare roll is blocked in thereserve area 40 a. - Continued discharge of the toilet-
paper web 56 reduces the diameter of the toilet-paper roll 14 in use, so that as the toilet-paper roll 14 continues to be consumed, it keeps moving towards theejection section 40 d. - When the toilet-
paper roll 14 in use has reached a radius that substantially corresponds to the distance A between the end of thesecond arm 88 or the end of the unrollingsection 40 c and a surface of thelimit stop 72, thesleeve 54 falls into the vertically extendingejection section 40 d and is guided through thedischarge section 40 e into the collection section 36 f. - The
limit stop 72 of the present invention possesses aconvex surface 73 and is embodied as a bolt that extends between thefirst wall 28 and thesecond wall 30, whereby a distance between the end of thesecond arm 28 or the end of the unrollingsection 40 c and thesurface 73 of thebolt 72 corresponds substantially to the radius of thesleeve 54 holding the toilet-paper roll, so that when the toilet-paper web 56 has been consumed, gravity forces the sleeve to fall into theejection section 40 d. - Since this invention's
limit stop 72 possesses a convex surface, it can be ensured that the toilet-paper roll 14 in use can be unrolled in both directions. Since the toilet-paper roll 14 can be unrolled in a plane that is parallel to the rear wall, one achieves the further advantage that thepaper web 56 can be tom off at the tear-offelement 62 if the toilet-paper roll unrolls to the right or at the tear-offelement 60 if the toilet-paper roll unrolls to the left. The surface may possess a surface texture in the form of grooving along the transverse or longitudinal direction. - Compared to the prior art, one realizes the advantage that independently of the diameter of the toilet-paper rolls 12, 14, the
holder 10 can be realized with a low building depth, whereby the toilet-paper rolls 12, 14 can be inserted independently of their winding direction, which facilitates a particularly simple and error-free servicing, since service-personnel during insertion of the toilet-paper rolls does not have to pay attention to the winding direction. - The
holder 10 is further characterized in that the limit stop in the form of thebolt 72 can be arranged in different positions.FIG. 4 shows abolt 72′ in a position in which the distance between thebolt 72′ and an end of thesecond arm 88 has been reduced. This creates the option of being able to use paper rolls withsleeves 54′ of a smaller diameter. Embodied in thewalls bolt 72 for higher-diameter sleeves 54 or thebolt 72′ for lower-diameter sleeves. - In addition to the invention's embodiment of the
limit stop 72 with a convex surface, the construction of the holdingdevice 12 is further characterized by a particularly uncomplicated mechanical design. For example, thewalls walls nubs 92 for fixing the position of theguide elements openings 94, which are first fitted and subsequently welded to the studs ornubs 92, for example by heat application. -
FIG. 6 shows a sectional view of thehinge 76 that secures in position thepivotable lever 64 in a pivotably hinged manner. Thehinge 76 comprises ashaft 96 that extends through arecess 98 of thepivotable lever 64 and is fixed in position in arecess 100 of thewall 28. - Provided to establish a spacing between the
posterior wall 28 and theanterior wall 30 arespacer elements sections elements posterior wall 28 and can be connected, i.e. welded, to a marginal section of theanterior wall 30. -
FIG. 7 shows a front view of the openedholder 10 without toilet-paper rolls 12, 14. Theguide 40 is mounted to thewall 28. As already explained with respect toFIG. 4 , theguide 40 comprises several sections, namely afirst section 40 a as reserve section for accommodating the spare toilet-paper roll 12, a second, vertically extendingsection 40 b that forms a feed section for delivering the toilet-paper roll into a position where it is available to the user, as well as athird section 40 c, which extends inclined relative to the vertical and acts as an unrolling section, which in turn serves to use the weight of the toilet-paper roll 14 to guide the latter to alateral limit stop 72, whereby the circumference of the toilet-paper roll 14 in use is in contact with thesurface 73 of thelimit stop 72. - The
guide 40 is bordered by thefirst guide element 64 and thesecond guide element 66. Theguide elements wall 28 and form the substantiallyU-shaped guide 40. - In an embodiment with its own inventive merit, a
locking element 110 is arranged along the extent of theguide 40 to prevent a user's manual action from pushing upward the lower toilet-paper roll 14 that is currently in use, i.e. in the direction of thevertical feed section 40 c. The lockingelement 110 is arranged in the unrollingsection 40 c that extends inclined to the vertical. In this, the lockingelement 110 is embodied as a sliding element that is arranged in a section of thesecond guide element 66 that extends inclined to the vertical. The slidingelement 110 is mounted transversely in the guide in the second guide element, slideable along the direction of the arrow 112, whereby in the closed position, oneend 114 of the slidingelement 110 bears upon thefirst guide element 64. - The
end 114 of the sliding element protruding into the guide is embodied wedge-shaped on its infeed side and possesses anoblique surface 114, so that theend 40 of the shaft or shaft journal of a toilet-paper roll moving from the feed section into the unrolling section causes the slidingelement 110 to open. - This ensures that the sliding element will be lifted during the passage of the shaft end or shaft journal and will fall back into its original position, either due to gravity or spring bias, after the shaft end or shaft journal has passed, which prevents the toilet-paper roll from being pushed back.
- During a motion in the opposite direction, the end of the shaft or the shaft journal is moved against a
straight surface 118 of the slidingelement 110, so that the latter remains in the closed position, as is illustrated inFIG. 8 . This prevents that pushing back the lower toilet-paper roll 14 can inadvertently release the spare toilet-paper roll 12 from its position in thespare section 40 a. The slidingelement 110 preferably is supported inclined relative to the vertical, so it falls from its open position into the closed position under the influence of gravity. But it is also possible for the slidingelement 100 to be mounted slideable under spring tension in thesecond guide element 66.
