Definitions

• the invention relates to the technical sector of dispensing devices for wiping paper in cellulose wadding, crepe paper, and similar materials intended more particularly for wiping the hands of toilet paper users.
• a rack means is mounted on the drum shaft and has a plurality of teeth forming a rack, the first teeth being of constant profile, the following with progressive profile, to cause the movements of the cutting blade. Furthermore, the blade has at its end capable of being placed opposite the rack means a fixed part forming a heel having a plurality of teeth forming a pinion and being disposed in progressive distance from the axis of the blade, the tooth d attack being of greater height to ensure meshing.
• This heel-forming part is integral with the axis of the blade in an eccentric position, so as to cause the angular pivoting of the blade and of the heel-forming part.
• the toothed heel mechanism (8) comprises an arm (8a) articulated against an elastic return means (12) relative to the blade holder, said arm having a curvilinear shape with a plurality of teeth (8d) capable of cooperating with the rack means (9) in an elastically floating assembly, and forming an angulation ( ⁇ l) defined by the point of attack of the gear, the articulation axis of the toothed heel and the blade cutting area according to YOY which is of the order of 160 to 170 °.
• Figure 1 is a side view of the dispensing device according to the prior art defined in particular in patent FR 2701016
• FIG. 2 is a perspective view before assembly of the device of the invention allowing a reduction in the tensile force
• FIG. 3 is a schematic view illustrating the position of the cutting device and the blade in the initial phase of rotation of the drum before cutting.
• Figure 4 is a view according to Figure 3 in a cutting position of the strip of material after partial rotation of the drum.
• FIG. 5 is a view according to Figures 3 and 4 in the final phase of rotation of the drum, and return thereof after cutting.
• Figure 6 is a front view in partial section according to Figure 2 of the mounted device.
• the dispenser for hand towels and toilet paper referenced as a whole by (1), comprises a casing (2) molded in plastic material capable of receiving in its upper part a coil (3) for supplying wiping material or toilet paper held between attached upper flanges (4), on the bottom of the housing or otherwise.
• Lower flanges (5) are attached to the bottom face (2a) of the casing and are fitted with notches allowing the fixing and mounting of the drum (6), which includes a cutting device (7) with a serrated blade (7a ).
• This cutting device is particular in the manner described above with an arrangement on one of the sides of the drum which comprises a serrated heel mechanism (8) associated with the cutting blade which cooperates with a fixed rack (9) established on the inner blank (5b) of said flange (5) of the casing.
• the drum has a longitudinal opening (6f) allowing the passage and exit of the cutting blade.
• the drum is arranged in a known manner on its other side with an arrangement not shown in the drawings and corresponding to the teaching of French patent 76.04664, and including a launching and return mechanism with eccentric and spring
• the apparatus further comprises means presser (11) in the form of a cylinder and of a length corresponding to that of the drum which is capable of being supported thereon, being positioned between the abovementioned flanges (5).
• the fixed rack (9) comprises a plurality of teeth (9a) established in the profile and configuration defined in patent FR 2701016.
• the heel mechanism (8) is arranged in that it includes an articulated arm
• the latter comprises at its base (8.b) a form ring capable of pivotally engaging on a finger (13. a) projecting from a fixed boss (13b) established on the blade holder in an attached or molded manner.
• Said arm (8a) extends in its front part in the shape of a curvilinear sector (8 c), the upper face of which has a plurality of teeth of the type corresponding to the teeth (8d) formed on the toothed heel described in patent 2701016. Said arm is therefore susceptible to a floating elastic mounting joint.
• the said arm When the drum is rotated for cutting, the said arm is liable to move away from the blade holder of the cutting device, thus modifying the angulation ( ⁇ l) which is defined by the point of attack of the gear, the hinge axis of the toothed heel and the blade cutting area.
• An angulation according to YOY is thus obtained which is of the order of 160 to 170 °. This amplitude is substantially constant during the rotation of the drum.
