Holder for toilet paper rolls

The invention "relates to a holder for toilet paper rolls and more particularly relates to a holder that holds a plurality of toilet paper rolls in in such a way that whenever a roll of paper is in the delivery position or in use position is located, has been consumed, the empty core ■ is immediately ejected from the consumption position and at the same time another replacement roll is brought into the now free usage position.

Maa already has a wide variety of loilette roll holders proposed and applied in practice. In one of the known holder of this type is to the empty core of the paper roll, which is in the consumer

position and has been used to eject and a new roll of paper is now in the use position to bring a relatively complicated and expensive transfer mechanism is required. Venn if a simpler and cheaper transfer mechanism has already been proposed, it must but here the ejection of the empty core from the position of use and the introduction of a new one Role in the consumption position can be made in two separate steps.

The main aim of the invention is therefore an improved holder for toilet paper rolls, in which always when a toilet roll in the consumption position is used up, the empty core of the used one Holle ejected from the consumption position and at the same time a new replacement role in the now free consumption position is introduced.

Another object of the present invention is a relatively simple transfer device which the ejection of the empty core from the consumption position and the introduction of the replacement roll into the after Consumption position vacated after the Eern was expelled can do in a single step.

Further objects of the invention are evident from the following Description. In the description, with reference to the accompanying drawing, which one is preferred Embodiment of the invention shows the invention explained in detail.

Fig. 5 corresponds to Fig. 4- and shows a discussed one Embodiment of the part for receiving the paper roll and for ejecting the core.

The present invention will now be explained in more detail with reference to FIGS Applicable embodiment of a holder for toilet paper rolls is illustrated. Of the Holder is designated as a whole by the reference numeral 1 and consists essentially of one essentially right-angled, one-piece housing 2 extending in the vertical direction with right-angled

Cross section in plan view. The housing is open at the top and bottom and has two opposing side walls 3, 3, a rear wall 4 and a front wall 5 which is shorter than the rear wall and its upper and lower ends just before the corresponding ends of the rear W ^ nd end. The open upper end of the housing is normally closed by an upper lid 6 which is arcuate and is hinged to its rear end at the upper end of the housing 1 by a transverse pivot pin 7 which is suitably with its opposite ends in the side walls 3 of the housing is mounted. The lower end of the housing 1 is also normally closed by a lower cover 8, which also has a substantially arcuate cross-section and is hinged to its rear end at the lower end of the housing 1 by a transverse pivot pin 9 which in turn is suitably connected to its opposite ends is mounted in the side walls 3 of the GeMuses. When the upper and lower covers 6 and 8 are in the closed position, the front ends of the covers seal against the upper and lower ends, respectively, of the front wall 5 of the housing. For this purpose, the free front ends of the two covers are designed to be offset and engage the ends of the front wall 5, which are also offset. The upper lid 6 is pivoted into the open position when one or more toilet paper rolls S are to be inserted into the housing 1, while the lower lid 8 is then moved into the open position when

409828/0244

empty cores G of the toilet paper rolls, which are used up or almost used up, are to be removed from the holder. In FIGS. 1 and 2, three toilet paper rolls are indicated within "the housing 1, which lie one above the other and whose axes are horizontal and parallel to one another. The rollers are denoted by the reference characters R, R 'and R ", the lower roller R being in the use position, while the other rollers R ¹ and R ¹ ' are in the reserve position a delivery opening 10 which is close to the paper roll R, which is in the consumption position, so that the user can grasp the front end of the roll R with his fingers and pull it out. Near or slightly above the lower edge of the delivery opening and At a small distance from this edge, a tear-off strip 11 runs in the transverse direction, which has a saw-tooth-like edge 12 at the lower end of the strip te is provided along which the withdrawn end of the roll R can be separated from the rest of the roll. Put more clearly; the user grasps the leading end of the roll, pulls it out to a desired length and tears it up and along the severing edge 12.

The inner surface of each side wall 3 of the housing is provided with a first elevation 13, which from the upper End of the relevant side wall 3 vertically downwards to approximately the middle of the side wall 3 and from the rear wall 4 · until just before the middle of the width of the wall 3 extends. Further is the inner surface of each side wall

409828/0244

provided with a wide, shorter elevation 13 'which extends vertically downward from the upper end of the side wall in question and laterally from the front wall 5 to the first elevation that between the opposing inner edges of the two elevations 13 and 13' a guide groove 14 is formed, which can accommodate and guide the core of a paper roll. The width of this groove 14 is slightly larger than the diameter of the core of a conventional toilet paper roll, so that the core can freely fit into the guides 14, 14 and is guided therein. The lower end of the second, shorter elevation 13 'lies in a plane which is above the plane of the lower end of the first, longer elevation. The purpose of this measure is explained below. In this way it is achieved that each of the guide grooves 14, 14 has two side boundaries with different lengths. Inside the housing there is now an integrally formed, reciprocating part 20 for receiving a paper roll and for ejecting the core, which is arranged below the guide grooves 14, 14 for the core and in a suitable manner in the opposing side walls. 3 ₅ 3 of the housing is pivotably mounted. The part 20 is provided with two similar, at a distance from and parallel to one another, upwardly projecting arms 21, 21 which lie on opposite ends of the part 20.

As best seen in FIGS. 2 and 3, the arms 21, 21 are in the form of a pawl, the upper ones

409828/0244

Ends 22 are essentially horizontal and normally engage on the underside of one end of the core of a paper roll ^ namely the paper roll Ε ¹ , which is the lower of the reserve rolls in the housing. The arms 22 prevent this paper roll E 'from accidentally falling down Ms into the consumption position if there is still a paper roll E in this position which has not yet been used up. The lower portions of the arms 21 $ 21 bulge rearwardly and are also integrally connected to one another by a transverse connector 23 which is integral with the arms 21 ₉ 21 and extends across the front edges of the lower portions of the arms. The arms 21, 21 are provided with aligned holes 21 ' _s 21 ^s near their upper ends _s which receive pivot pins 15 ₉ 15 ^ which protrude inward from the opposite side walls 3 ₉ 3 of the housing 1 and the part 20 in the wise store ₉ that it is about these pins 15? 15 can be swiveled ο Each side edge of the housing 3? 3 is internally provided integrally with an arcuate guide track 16, the sliding and guiding the upwardly curved bottom surface of the corresponding arm 21 of the rockable member 20 receives "The arcuate guide tracks 16, 16 extend from the housing front wall 5 towards the housing rear wall 4 _S wherein the concave curved surfaces are at the top ₉ and end just before the rear wall at a distance _s which is slightly larger than the diameter of the core of a paper roll »The rear edge of each arm 21, 21 is larger _{with an upper 9.}

arc-shaped recess 21a and a lower, smaller, arc-shaped recess 21b, both of which are separated from one another by an intermediate projection 21c. The recesses 21a, 21a serve as a guide for the core of the lower Eeeerverolle S ¹ when it is to move from the reserve position to the consumption position, while the recesses 21b, 21T> are provided as a holding device for the core of the paper roll, which are in the consumption position is. For this purpose, the recesses 21b, 21b have a radius of curvature which essentially corresponds to the shape of the core of the paper rolls. The dimensions of the part 20 and the position of the holes 21 ', 21' in the arms 21, 21 of the part are chosen such that the center of gravity of the part is below the middle of its height, so that the part is clockwise by the weight of the full Paper roll, which rests on the guide tracks 16, 16, is pivoted into the fully extended position and pivots into the dot-dash position when the paper roll is used up. In the position of the part 20 shown in full lines, the upper ends 22, 22 of the arms 21, 21 of the part 20 enter the guide grooves 14, 14 and come to rest on the underside of the opposite ends of the core C ^{1 of} the lower ones Reserve ^{role R 1} , which prevents this role R ¹ from falling down from the reserve position. When the role R is consumed in the consumption position, the part 20 is counterclockwise into the one shown in phantom in FIG

Positioned pivoted so that the now empty core 0: "·.-_ ■■ · ■ - from the guide tracks 16, 16 through the space between the rear ends of the tracks 16, 16 and the back wall 4 in. the collecting space for empty cores falls, which is EADERSHIP tracks below the "16 and rotating the · tracks themselves, the bottom lid 8 and the rear wall 4 of the housing is formed. in order to forcibly the (part 20 from the fully extended position shown in To move the dot-dash position, an actuating button 24 is provided on the outer surface of an arm 21 (seen in FIG. 3 on the right arm) which protrudes through a slot 17 provided in the side wall 3 and can be actuated from the outside (Fig. 4 When it is desired to eject an empty core C, of which the paper has been used up, the user grasps the button 24 and pulls it backwards in the slot 17 until the rope 20 has reached the position indicated in FIG , whereupon the empty core C from the F Guide tracks 16, 16 falls through the gap into the collecting space, while at the same time the upper ends 22, 22 of the arms 21, 21 release the hats 14, 14 so that they come free from the opposite ends of the core C ^{1 of} the lower heaver roll E * and allow this role H ¹ to fall into the consumption position in which the opposite ends of the core C of the target S 'rest on the miter tracks 16,16.

Venn it is assumed that the holder of the invention according to its occupies, starting position, in which three full 3? OjLlettenj> apierrollen R> ^Rl and H ^{1 f,} as shown in? Ig.

409828/0244

1 and 2, are in the holder ″, ie in which the roller R assumes the consumption position, while the rollers R ¹ and R ¹ 'are superimposed on one another and with their
Cores G ¹ and C ¹ 'are in the hats 14-, 14- lying in the reserve position, the opposite ends of the core C of the roll R in the consumption position are supported by the track tracks 16, 16, whereby they are at one _; accidental stepping out of these tracks can be prevented by the second recesses 21b, 21b. The two roles R ¹ and R ¹ ', in the
Reserve positions are prevented from accidentally falling down by the horizontal upper ends 22, 22 of the arms 21, 21 of the reciprocating part 20 which bear against the lower side of the core C of the reel R ¹ . When a full toilet roll is in the use position, the
When the core rests on the guide tracks 16, 16, the part 20 is pivoted clockwise in FIG. 2 to such an extent that it comes to rest on the front wall 5 of the housing due to the weight of the paper roll.

For this reason, the distance D between the bottom of the recess 21b and the front edge of the arm 21 is dimensioned so that it corresponds essentially to the thickness of the paper layers of a full toilet paper roll.
As the diameter of the roll of paper gradually decreases as the paper is used up, the part 20 is gradually replaced by the weight of the lower portions of the
Part 20 is pivoted counterclockwise about the pivot pins 15, 15 and slides along the guide tracks 16, 16 to the rear, the core C along the

409828/0244

iHihrungsbahnen 16, 16 is pushed back towards the exit gap. When the paper roll, which is in the consumption position, is used up or almost used up, the center of gravity of the arms 21, 21 of the part 20 comes to lie in a plane which is perpendicular to the axis of the pivot pins 15t 15, whereupon the movement of the part 20 counterclockwise stops, so that the core is not pushed backwards either. The user then pushes the button 24 backwards along the slot 17 and thereby rotates the part 20 further about the pins 15, 15 counterclockwise, so that the part 20 moves even further backwards along the guide tracks 16, 16 and while pushing the empty core G over the rear edges of the webs 16, 16 into the collecting space. Since the upper ends 2, 22 of the arms 21, 21 of the part 20 retreat from the grooves 14, 14 in the side walls 3, 3 and ^{release the core C of the hollow E 1} when the part 20 reaches its end position of counter-clockwise movement reached, the lower reserve paper roll R 'can fall into the consumption position, pivoting the part 20 about the pivot pins 15, 15 clockwise so that the upper ends 22, 22 of the arms 21, 31 into the grooves 14, 14 advance and the opposite ends of the core C ¹ 'of the last paper roll R ¹ ' can come to rest on the upper ends in the reserve position. The entry of the paper roll R ¹ into the "consumption position" is determined by the above-explained special design of the rear edges of the arms 21, - 21 and by the guideways

16, 16 accelerated, the role being effective at it it is prevented that, when it falls into the consumption position, it ricochets off the tracks 16, 16. It however, the possibility of ricochet may occur, when the roller hits the projections 21c of the arms 21, 21 when the roller is out of reserve slides along the rear edges of the arms into the consumption position; however, since the core is loosely in the sleeve is inserted on which the paper roll is wound, so that the core is relative to this Can move the sleeve radially, can rebound by such a radial movement of the core relative to the Sleeve to be absorbed.

In Fig. 5 a modification of the connecting part is shown, which connects the arms 21, 21 of the reciprocating part 20 with each other. The modified part is denoted here by the reference numeral 23a. A part of the modified connecting part 23a can be seen in the delivery opening 10 and is accessible through this opening. In the construction of the U ¹ Ig. 5 can therefore the button 24 and the slot 17 "as they are in Eig. 2 are not used. In order to eject the empty core here, the user pushes the connecting part 23a backwards so that the reciprocating part 20 is pivoted counterclockwise and slides backwards along the guide tracks 16, the empty core being pushed into the collecting space , and at the same time the next roll can fall from the reserve position into the now empty consumption position.
