Definitions

  • a carrying plate is adapted to be secured to a wall, and the pair of levers is swingably mounted on the carrying plate at the free end of one of the levers to swing about a common axis, and the free end of the other of the levers is disposed in a horizontal plane, higher than a horizontal plane extending through the rotary axis of the paper roll, so that upon pulling downwardly the end of the paper roll the latter is pressed towards the carrying plate and prevented from further rotation.
  • a separating knife is carried by the free end of the other of the levers, and the mandrel is rotatably mounted in the levers at least near to the bent portion of the latter.
  • the present invention relates to a tear-off device for rotatably mounted paper rolls, particularly toilet paper rolls in general, and to such toilet paper rolls in which, by the pressure upon the separating knife disposed at the end of a lever, the paper rolls are pressed toward a Wall plate and, thereby, are prevented from rotation, in particu'l'ar.
  • the rolls are mounted in a U-shalped carrying support with resilient leg members, the free ends of which are bent inwardly and which engage the open ends of the rolls; Furthermore, another U-shaped support is mounted with its free leg ends on the carrying support, the cross-members of which engage the roll and serve as separating knife.
  • a wall plate is provided for the mounting of the carrying support.
  • One end of each of the levers is swingalbly mounted about a common axis on a carrying plate, and the other free end of the levers carries the separating knife and the mounting for the paper roll is provided on the levers close or adjacent to its bent portion.
  • the paper strip is guided over the cross rail and is pressed against the carrying plate during the separating of the paper strip and is retained thereby.
  • FIGURE 1 is a side elevation of the tear-off device designed in accordance with the present invention.
  • FIG. 2 is a top plan view of the device disclosed in FIG. 1;
  • FIG. 3 is a side elevation of another embodiment of the tear-off device.
  • the tear-off device comprises a toilet paper roll 1, which is wound in conventional manner on a cardboard sleeve 2 and is mounted on a mandrel 3 having lateral pins 4.
  • the toilet paper roll l-ils mounted by means of the pins 4 in two levers 5 and 6 bent up sulbstantial'ly at a right angle, which levers 5 and 6 are disposed parallel to each other at a distance corresponding to the length of the roll 1 and which levers 5 and 6 are connected together by means of cross-members 7 and 8 to form a pair of levers.
  • the mounting of the roll 1 in the levers 5 and 6 takes place at about the center portion of the latter or close to the rectangular bend into two slots 9 and 10, respectively, provided in the levers 5 and 6.
  • the upwardly directed lever portion 5' and 6' is swingably mounted at its end on a carrying plate 11, which forms the rear wall and is secured to a wall face.
  • the joint swinging axis for both levers 5 and 6 is defined by two pins 12 and 13, from which the ends of the levers are suspended by means of bent slots 14.
  • the swinging axis of the levers 5 and 6 defined by the pins 12 and 13 is reanwardly set off relative to the hearing axis of the roll 1 defined by the pins 4, so that the roll engages the carrying plate 11.
  • the roll 1 could, however, also be suspended freely.
  • the pair of levers 5 and 6 swings slightly forwardly and the paper roll engaging the carrying pla'te 11 is removed from the latter, so that it can rotate freely.
  • the removed paper strip is pulled upwardly over the separating knife 15, whereby a lever movement is brought about in clock-Wise direction, and the roll 1 is pressed towards the carrying plate 11 and is braked, so that the paper strip is now secured for the purpose of easier separation of the paper strip.
  • this embodiment follows substantially the embodiment disclosed in FIGS. 1 and 2.
  • the paper roll 1 is not pressed directly towards the carrying plate 11, rather a cross-bar 16 is provided between the lever portions 5 and 6', over which cross-bar 16 the paper strip runs towards the separating knife 15.
  • the paper strip is clamped during the separation between the crossbar 16 and the carrying plate 11 by the mentioned lever movement in clock-wise direction.
  • the cross-bar 16 In order to permit the mounting of a complete or full paper roll, the cross-bar 16 must be disposed at a distance from the bearing pins 9 and 10 for the roll 1 in the direction towards the swinging pins 12 and 13, which is larger than the radius of the full roll.
  • the tear-off device is preferably made of synthetic material.
  • a mandrel adapted to support rotatably a paper roll
  • a carrying plate adapted to be secured to a wall
  • said pair of levers being swingably mounted on said carrying plate at the free end of one of said levers to swing about a common axis, and the free end of the other of said levers being disposed in a horizontal plane higher than a horizontal plane extending through the rotary axis of said paper roll, so that upon pulling downwardly the end of said paper roll the latter is pressed towards said carrying plate and prevented from further rotation,
  • said mandrel being rotatably mounted in said levers at least near to the bent portion of the latter.
  • the tear-off device as set forth in claim 1, which includes:
  • a mandrel adapted to support rotatably a paper roll
  • a carrying plate adapted to be secured to a wall
  • levers being swingably mounted on said carrying plate to swing about a common axis
  • said mandrel being rotatably mounted in said levers at least near to the bent portion of the latter
  • said distance being greater than the radius of said paper roll.
