Definitions

  • the invention relates to an adhesive tape dispenser.
  • Adhesive tape dispensers are sufficiently known from the prior art.
  • the EP 2 966 019 A2 discloses an adhesive tape dispenser for a roll of adhesive tape with a core element, the dispenser essentially consisting of a carrier unit.
  • the document also discloses a metal bracket which presses a section of adhesive tape onto an application roller.
  • a problem with the prior art is that adhesive tape can peel off too early from the adhesive tape dispenser. Here it can happen that detached adhesive tape sections are connected again to the adhesive tape roll, which makes it difficult to detach them again. Adhesive tape sections can also be knotted, in which case, in view of the adhesive effect of the adhesive tape, untying is not possible and / or very time-consuming. A further problem can be the tearing of the adhesive tape if the forces acting on the adhesive tape become too strong.
  • tape dispensers can be very noisy when applying tape. Since professional adhesive tape dispensers are often used for hours and several days a week, this high volume can be a burden for the employee, and in extreme cases it can also affect the employee's health. It is therefore advantageous if the adhesive tape dispenser applies adhesive tape with as little noise as possible.
  • the object of the present invention was therefore to overcome the disadvantages of the prior art and in particular to provide an adhesive tape dispenser with which adhesive tape can be applied particularly reliably, comfortably and with little noise.
  • an adhesive tape dispenser comprising a handle, a receiving device with a preferably pivotable and / or rotatable one pivotable and rotatable bearing for a roll of adhesive tape, an application device with an, in particular rotatable, application roller, a rotationally fixed friction bridge with a bridge sliding surface and a deflection bead, in particular a deflection bead with a transverse elevation, preferably a transverse curvature, the adhesive tape dispenser being designed and set up so that a Adhesive tape section of a roll of adhesive tape present on the bearing, in particular rotatably mounted, slides or can slide over the bridge sliding surface or at least over the deflecting bead, in particular over the transverse elevation or deflecting contact surface of the deflecting bead, and optionally then over the bridge sliding surface, when it unrolls over the bridge sliding surface, before it hits the application device meets.
  • the handle can preferably be designed as a tangential or radial handle.
  • the roll of adhesive tape can optionally be part of the adhesive tape dispenser, but preference is given to an adhesive tape dispenser without an adhesive tape roll, which can, however, receive an adhesive tape roll in the manner described above.
  • the friction bridge with the deflecting bead improves the application of adhesive tape sections quite considerably. It is assumed - without being bound by a theory - that attractive interactions act between the deflecting bead, in particular the transverse elevation or the deflecting contact surface of the deflecting bead, and in particular also the bridge sliding surface and the adhesive tape section placed on it, which increase the likelihood of inadvertent detachment of the adhering adhesive tape section to decrease. Among other things, these can also be Van der Waals forces.
  • the friction bridge according to the invention considerably improves the applicability of the adhesive tape and reduces the probability of the adhesive tape becoming knotted.
  • the bridge sliding surface preferably functions as a sliding or contact surface for the adhesive tape sliding along it, preferably its non-adhesive back, but can also only or additionally serve as a contact surface.
  • the bridge sliding surface after leaving the deflection bead, when it is guided past the so-called bridge sliding surface, or only in sections, does not come into contact with the bridge sliding surface.
  • the bridge sliding surface can also be referred to simply as the bridge surface.
  • an adhesive tape dispenser comprising a handle in the form of a radial handle, a receiving device with a, in particular pivotable and / or rotatable, bearing, in particular a central bearing, for an adhesive tape roll, an application device with an, in particular rotatable, application roller, the Radial handle has a longitudinal axis, the longitudinal axis, in particular the radial handle, and the application roller being on opposite sides of an intermediate plane, the intermediate plane being arranged parallel to the longitudinal axis of the radial handle and the bearing axis of the bearing, in particular the central bearing, in a first storage position in the intermediate plane and / or wherein the application roller and the bearing, in particular the central bearing, are located on the same side with respect to the longitudinal axis when a cross section is viewed orthogonally to the bearing axis.
  • the intermediate level is a level to be constructed hypothetically and not, for example, an actual device object of the adhesive tape dispenser device according to the invention.
  • the adhesive tape dispenser also in this embodiment comprises a rotationally fixed friction bridge with a bridge sliding surface and a deflection bead, the adhesive tape dispenser being designed and set up in such a way that an adhesive tape section of an adhesive tape roll present on the bearing, in particular rotatably mounted, when rolling over the deflection bead and possibly also slides or can slide over the bridge sliding surface before it hits the application device.
  • the radial handle allows a particularly compact design if its longitudinal axis is arranged as described above.
  • the receiving device and the application roller are preferably on the same side of the longitudinal axis.
  • the receiving device preferably also comprises a mechanism in order to pivot the bearing, in particular the central bearing, out of the first storage position into a second storage position.
  • the bearing is preferably attached to a pivotable swivel arm.
  • the bearing is preferably rotatable and pivotable, in particular rotatable about its own bearing axis and pivotable by pivoting the swivel arm about a swivel arm axis, particularly preferably the position of the bearing axis from deviates from the position of the pivot arm axis and / or wherein said axes are essentially parallel.
  • the bearing, in particular the central bearing is preferably preloaded in order to move from the first to the second bearing position.
  • the bearing will be at or near the first storage position and as the amount of tape on the tape roll decreases, the bearing will automatically move closer to the second storage position. This ensures that the friction bridge is always positioned close to the roll of adhesive tape.
  • the first bearing position is preferably meant, unless the context indicates otherwise.
  • the first storage position is preferably a position which is located in the center of a cylindrical housing for the roll of adhesive tape.
  • a "handle" within the meaning of the present invention can take various forms. Tangential and radial handles have proven particularly useful. With the radial handle, the handle points with its longitudinal axis in the direction of the bearing, in particular in the first bearing position.
  • the longitudinal axis of a radial handle does not necessarily have to lead directly through the bearing in the first storage position and / or the bearing axis in the first storage position, but preferably close past this, in particular not more than 3 cm, particularly preferably not more than 2 cm, spaced from the bearing and / or the bearing axis in the first bearing position, where the distance between the longitudinal axis and said bearing or said bearing axis in the first bearing position is shortest.
  • the shortest distance between the longitudinal axis and the bearing is present in the first bearing position on the other side of the radial handle.
  • the handle with its longitudinal axis does not point to the bearing, in particular in the first and second bearing position.
  • the longitudinal axis of the handle is further away from the bearing and / or the bearing axis than with the radial handle, in particular also where the distance between the longitudinal axis and said bearing or said bearing axis is shortest, more than 3 cm, in particular more than 4 cm, particularly preferably more than 5 cm apart, especially in the first and / or second storage position.
  • the shortest distance between the longitudinal axis and the bearing, in particular in the first bearing position is present at a point on the longitudinal axis within the tangential handle.

  • the longitudinal axis of a tangential handle does not usually come close to the roll of adhesive tape in the generic use, in particular has a minimum distance of 3 cm from the outer area the roll of tape.
  • the longitudinal axis of the handle can also be referred to as the handle axis.
  • Both tangential and radial handles can have a cylindrical basic shape, in which the cross-section is mostly not round, but elliptical. Tangential and radial handles are preferably constructed linearly and not curved.
  • an "adhesive tape section" within the meaning of the present invention can be connected to the roll of adhesive tape, but is preferably no longer attached radially to the core of the roll of adhesive tape, but detached, but preferably still connected at the end to the remaining roll of adhesive tape. It is therefore an adhesive tape section which protrudes completely or partially from the adhesive tape roll and which is connected to the adhesive tape roll at the end and / or in one piece if it has not yet been cut off.
  • the adhesive tape section usually comprises an adhesive adhesive tape side and an opposing non-adhesive adhesive tape side. This is usually achieved by coating the adhesive tape with an adhesive layer on only one side. After applying the adhesive tape section with the adhesive tape dispenser, i.
  • the section of adhesive tape After the section of adhesive tape has been applied to a surface, it is usually cut off and a further section of adhesive tape can be applied. Said further adhesive tape section has already been completely or partially detached from the adhesive tape at the time of cutting. It should be pointed out that the roll of adhesive tape and the section of adhesive tape are only optional components of the adhesive tape dispenser and that an adhesive tape dispenser without a roll of adhesive tape is also claimed.
  • non-rotatably means that the corresponding element is not attached in a rotatable manner, for example connected in one piece with it or glued or screwed on.
  • the tape dispenser can be turned as a whole by a user, and so can the non-rotating elements.
  • a rotationally fixed element does not rotate with respect to the main body of the rest of the adhesive tape dispenser, in particular not with respect to the handle or possibly the housing.
  • the reference system is therefore the adhesive tape dispenser itself, for example also the handle and possibly the housing of the adhesive tape dispenser.
  • a rotatable element is rotatably connected to the rest of the adhesive tape dispenser.
  • the corresponding element can also preferably not perform any partial rotational and / or pivoting movement with respect to the reference system.

  • the deflecting bead comprises a transverse elevation, in particular a transverse arch.
