Transportable dispenser for foils

Description

The invention relates to a transportable dispensing device for films which can preferably be labeled, with a housing having an interior for receiving a film roll, elongated in the direction of the roll axis, with suspension means arranged on the housing, with an outlet gap for the film pulled off the roll and extending in the longitudinal direction over the housing with a separating device arranged at a distance from the outlet gap for separating a piece of film pulled off the film roll. A transportable dispensing device of the type mentioned is primarily intended for inscribable and / or printed films which, after being pulled off the dispensing device, can be fixed on a base, for example with releasable adhesives or electrostatic means, on a base. Dispensing devices of this type are known, for example, from WO 94/25294. The dispensing device there has a housing with a square cross section, which is inserted into a channel-shaped suspension device arranged on the upper edge of a vertical plate. The film is over a

Exit gap pulled down. The removed film piece can be separated from the film roll using a separating device arranged under the outlet gap. Proceeding from this, the object of the invention is to develop a transportable dispensing device of the type specified at the outset, which is easy to handle and can be hung on plates with different wall thicknesses.

To achieve this object, it is proposed according to the invention that the housing has an undercut groove which extends in its longitudinal direction and is open at the top and undercuts, into which two suspension brackets forming the suspension means with a bearing piece around the channel axis are pivotable and longitudinally displaceable between two end positions intervene, wherein the suspension brackets have a curvature that partially encompasses the housing in one end position in the circumferential direction and on the concave side facing the housing a plurality of mutually parallel, essentially triangular in cross section, with its triangular tip pointing towards the housing and at its edges in the longitudinal direction of the housing have aligned support ribs. With these measures, it is possible to reliably hang up the dispensing device on the upper edge of walls with different wall thicknesses and different widths in a few simple steps. The free triangular tips of the support ribs expediently span a partially cylindrical surface. The support ribs are advantageously designed as isosceles triangles with an arc-shaped base in cross section, the tip angle of the support ribs expediently being 70 ° to 110 °, preferably 90 °. The La Pieces are expediently designed as cylinder tubes integrally formed on the suspension brackets, which can be equipped with front-side cover parts made of an elastomeric or thermoplastic material, the diameter of which is somewhat larger than that of the bearing pieces. The

Cover hurry ensure that the suspension bracket with low tolerance slide in the gutter without excessive material abrasion. The cover parts also have a spring function, which can be used in the transport position when the suspension bracket is locked onto the housing. The suspension bracket can also be provided at its free end opposite the bearing piece with an end catch rib arranged at a distance from the last support rib, which is higher than the support ribs and which ensures that the dispensing device cannot slide off the suspension edge even if the suspension is faulty. Another function of the catch rib is that of a locking element in cooperation with a locking rib arranged on the housing.

A further preferred embodiment of the invention provides that the housing has two half-shells which can be pivoted relative to one another about an axis of articulation parallel to the longitudinal axis of the housing, one of which is provided with the upwardly open groove for the suspension bracket, the other of which has a receiving trough for has the film roll and between which there is a joint gap on the joint side and a closed on the housing side opposite the joint side. the opening gap forming the film for the film is formed immediately. The half-shells are expediently designed as extruded parts made of aluminum or as extruded parts made of plastic, which can be closed at their open front ends by end caps, preferably made of plastic. The end caps are expediently fastened to the half-shell carrying the suspension bracket, preferably by means of a latching connection, while they can be locked to the other half-shell with the aid of a locking mechanism.

The locking mechanism expediently each has an actuating element arranged on the end caps, preferably displaceable in the longitudinal direction of the housing, while the half-shells each have a closing rib which delimits the opening gap and points towards the inside of the housing, the actuating elements each having a locking piece which is open to the half-shells, preferably with a U-shaped profile have, which in the closed state overlaps the closing ribs of the two half-shells over the opening gap and in the open state releases for mutual pivoting of the half-shells. The actuating elements are expediently displaceable against the force of a spring acting in the closing direction, so that they are held securely in their closed position.

The half-shells expediently have a cross section which is complementary to a circular or oval outline, the outlet gap when the housing is suspended points obliquely upwards, so that the film to be removed hangs down a little way over the casing surface. In one half-shell, at a distance from the exit gap, a knife-duct knife channel which is parallel to this is formed, while in the end caps a knife holder aligned with the knife channel in the closed state is arranged. When the housing is open, a knife holder equipped with a knife blade can be inserted into the knife receptacle so that it protrudes outward beyond the casing surface so that it can be moved along the knife channel from the knife holder when the housing is closed. The knife blade is expediently aligned so that its cutting edge encloses an angle of 28 ° ± 3 ° with the direction of displacement of the knife holder. In addition, in at least one of the end caps there is a transport receptacle for the knife holder that faces the interior of the housing.

A further preferred embodiment of the invention provides that a recessed grip parallel to the outlet shell and the knife channel is arranged in the lateral surface of the one half-shell, which ensures that the contact surface between the film pulled off via the outlet gap and the housing surface is minimized and that the film can be easily grasped with the fingers in the vicinity of the outlet gap.

A further advantageous embodiment of the invention provides that the suspension bracket the joint gap between see the two half-shells overlap in their closed state and are preferably releasably latchable with their catch ribs on an outside locking rib of the housing shell for transport purposes. In order to be able to easily transport the dispensing device, the end caps have an outside receptacle for a carrying belt, which preferably has a crosspiece.

To produce the articulated connection between the two half-shells, an articulated channel is arranged on one of the half-shells, which is delimited by two partially cylindrical joint surfaces which are concentric to one another and to the joint axis running in the housing shell or outside the housing shell, and in which one against the one Concentric joint shell adjacent to the articular surface and a guide bar of the other half shell bridging the distance between the joint shell and the other joint surface. The swivel angle between the shells is expediently limited to approximately 60 ° to 80 ° by stops arranged in the joint channel.

A further advantageous or alternative embodiment of the invention provides that the housing is intended for receiving a film roll with electrostatically charged or chargeable film, the outlet gap being limited at least on one side by an insulator material with a higher dielectric constant than the film material. In principle, it is possible that the housing itself is made of a plastic with a high rer dielectric constant than the film material. With both measures it is achieved that the film releases charge carriers when pulled out of the exit gap and is additionally charged electrostatically. When using a film material made of polypropylene or polyethylene, it is advantageous if the outlet gap is limited with an insulator material from the group consisting of polyamide, wool, silk, cellulose propyanate, cellulose acetate, polyethyl methacrylate, polyethylene terephthalate, polyvinyl chloride, polyacrylonitrile, polystyrene.

The invention is explained in more detail below with reference to an exemplary embodiment shown in the drawing in a schematic manner. Show it

The transportable dispensing device shown in the drawing is intended for receiving inscribable films in roll form. The dispensing device essentially consists of a housing 14 which has an interior 10 for receiving a film roll 12 and is elongated in the direction of the roll axis, two suspension brackets 16 which can be pivoted to a limited extent on the housing 14 and are longitudinally displaceable, and an outlet gap 18 which extends in the longitudinal direction over the housing film 20 pulled off the film roll 12 and a separating device 22 arranged at a distance from the outlet gap 18 for separating a piece of film pulled off the film roll. The housing 14 has two half-shells 26, 28 which can be pivoted relative to one another about a hinge axis 24 parallel to the longitudinal axis of the housing, one of which (26) is provided with an upwardly facing undercut groove 30 for receiving a cylindrical bearing piece 32 formed on the suspension brackets 16 the other (28) has a receiving trough 34 for the film roll 12, and between which a joint gap 36 is formed on the joint side and an opening gap which also forms the outlet gap 18 is formed on the housing side opposite the joint side. In the exemplary embodiment shown, the half-shells 26, 28 are designed as extruded parts made of aluminum, which are closed at their open ends by plastic end caps 38. The end caps 38 are on the half-shell 26 fastened with plug-in, snap-in and screw connections 40, 42 and lockable with the other half-shell 28 via a locking mechanism 44. The locking mechanism 44 each has an actuating element 46 which is arranged on the end caps 38 and can be displaced in the longitudinal direction of the housing and is provided with a locking piece 48 which is U-shaped in profile and points towards the half-shells. As a counterpart, the half-shells 26, 28 each have a closing rib 50, 52, which bounds the outlet and opening gap 18 and faces the interior 10 of the housing. In the closed state, the locking ribs 50, 52 of the two half-shells 26, 28 are overlapped by the locking pieces 48 beyond the exit and opening gap 18, while in the opening state of the housing, the locking pieces 48 are retracted into the end caps 38 and the mutual pivoting of the half-shells 26, Release 28.

As can be seen from FIG. 4, the outlet gap 18 points obliquely upwards on the housing 14 suspended on a plate-shaped wall element 54. In the half-shell 28 is at a distance below the; Rittsspalt 18 a parallel to this edge-open knife channel 56 is formed. Furthermore, in the end caps 38 a knife receptacle 58, which is aligned with the knife channel 56 in the closed state, is arranged, into which a knife holder 62 carrying a knife blade 60 can be inserted so as to protrude outwards so that it can be moved along the knife channel 56 when the housing is closed. As can be seen from Fig. 5a, the cutting edge 64 closes the Knife blade 60 forms an angle of approximately 28 ° with the direction of displacement of the knife holder. In the end caps 38 there are, in addition to the interior 10 of the housing, transport receptacles 66 (cf. FIGS. 2 and 3) in which the knife holder can be accommodated in a protected manner for transport purposes. In the lateral surface of the half-shell 28, between the exit gap 18 and the knife channel 56, there is a concave recess 68 which is parallel to the latter and which reduces the contact surface of the film pulled out of the exit gap 18 and which makes it easier to grasp the film 20.

The joint arranged between the two half-shells essentially consists of a joint channel 70 arranged on the one half-shell 28, which is delimited by two partially cylindrical joint surfaces 72, 74 concentric with one another and with the joint axis 24 and in which one abuts against the joint surface 72 Concentric joint shell 76 as well as a guide web 78 of the other half shell 26 engaging over the distance between the joint shell 76 and the other joint surface 74. The swivel angle between the two half-shells 26, 28 is limited to approximately 70 ° by stops 80, 82 arranged in the articulated channel (cf. FIG. 3).

The suspension bracket 16 engages with its cylindrical bearing piece 32 in the undercut groove 30 of the half-shell 26 and is pivoted and longitudinally displaceably mounted and guided in this between two end positions. At their front ends, the gerteile 32 equipped with thermoplastic cover parts 87, which protrude radially somewhat beyond the bearing pieces 32 and are supported radially on the inner surface of the groove 30. In their part projecting beyond the bearing piece 32, the suspension brackets 16 have a curvature which is adapted to the housing outline, with a plurality of juxtaposed, essentially triangular in cross section, with their tip 85 pointing towards the housing on the concave side facing the housing 14. de, aligned in the longitudinal direction of the housing support ribs 84 are formed. The tips 85 of the support ribs 84 span a partially cylindrical surface. The support ribs are formed as isosceles triangles with an arcuate base in cross section. In the exemplary embodiment shown, its tip angle is approximately 90 °. The supporting ribs 84 ensure that the suspension brackets 16 can be reliably anchored to wall elements 54 of different thicknesses (cf. FIGS. 3 and 4). At their free end opposite the bearing piece 32, the suspension brackets 16 have an end catch rib 86 which is arranged at a distance from the last support rib 84 and which is higher than the support ribs 84 and which, in the closed state, can be latched onto a locking rib 88 projecting beyond the jacket surface of the half-shell 28 . In the closed state, the suspension brackets 16 overlap the joint gap 36 and thereby additionally serve as a locking device.

The exit gap 18 is on the take-off side of the film 20 from one onto the edge of the half-shell 28. limited strip 90 made of polyamide, which has a higher dielectric constant with respect to the commonly used polypropylene film material. The film material is therefore charged electrostatically when pulled off via the strip 90. Of course, the film material on the film roll 12 can also be pre-charged electrostatically, so that additional charging on the bar 90 is not absolutely necessary. Due to the electrostatic charge, the removed film 20 has an adhesive effect, which makes it possible to attach the film to documents without additional adhesive.

In summary, the following can be stated: The invention relates to a transportable dispensing device for writable foils. The dispensing device has a housing 14 with an interior 10 for receiving a film roll 12, suspension means 16 arranged on the housing and an outlet gap 18 extending in the longitudinal direction over the housing for the film 20 pulled off the roll. In order to be able to reliably hang the housing on a vertical wall with a free upper edge and variable wall thickness, the housing 14 has an undercut gutter 30 which is open at the top and into which two suspension brackets forming the suspension means engage with limited pivoting and longitudinal displacement. The suspension brackets have a curvature which partially encloses the housing 14 in the one end position in the circumferential direction. They are also on the concave side facing the housing several support ribs 84 arranged side by side, triangular in cross section, with their triangular tip 85 pointing in the direction of the housing 14.
