• This device is arranged to allow the distribution of a reel of wiping material (B) which is presented in a frontal manner relative to the bottom wall (2a) of the casing of the device, so as to reveal one of its side faces, during tilting and opening of the cover (3).
• the cover is articulated in its lower part to the casing by means of a pivot pin (10), while, when it is closed, it is locked in position on the top of the casing by means (11) known to those skilled in the art.
• the reel of wiping material is positioned in the upper part of the device, at an appropriate height, according to its initial diameter.
• the device has in its lower part a mechanism for cutting the strip of material from the coil.
• This mechanism can be, for example, of the type described in the Applicant's prior patent N. FR 2,332,215.
• This mechanism comprises a drum (4) rotatably mounted with respect to lateral support flanges (12) and an axis (13) arranged in the lower part of the casing of the device.
• the cutting device (5 - 6) is integrated into the drum and means for launching and returning (7 - 8) the drum, with eccentric and spring, are suitably arranged according to the teaching of the aforementioned French patent.
• a pressure roller (14) can be placed in upper support on the drum, thus allowing the insertion of the end of the strip of paper coming from the spool between the drum and the pressure roller for later distribution.
• An operating button (15) is mounted at the end of the drum axis.
• the reel of material is mounted on a reel holder referenced as a whole by (16) which is capable of engaging, in turn, on a support piece (17) forming a hub integral with the rear rear wall (2a) of the housing.
• This support piece (17) has a profiled flange (17a), circular for example, which is capable of being fixed and engaging on a cylindrical shoulder (2b) established on the bottom face of the casing.
• This cylindrical shoulder is arranged projecting towards the front of the wall of the casing and allows fixing by screwing (18) or equivalent of the flange (17a).
• This support piece (17) has, in a plane perpendicular to its flange (17a) and towards the front, a bearing (17b) of great length, of cylindrical configuration, and allowing the centering and positioning of the reel holder (16 ). More particularly, this bearing (17b) has a bearing area (17bl) capable of receiving a part forming a sleeve (16a) of the reel holder (16).
• the end (17c) of this seat (17b) is tapered and has, at b ( out, a retractable and pivoting locking finger (19) whose function is to maintain the position in particular of the reel holder (16 ), as will be described below.
• the end (17c) of the bearing surface (17b) of the support piece (17) has, in a non-limiting configuration, slots (17d) between which is formed the locking finger (19) having a displacement capacity by flexibility and elasticity, a movement thereof, under the exercise of a pressing force (F).
• the finger (19) is thus in the form of a support tab (19a) with a projecting shape (19b) acting as a stop.
• the spool holder (16) comprises a long outer surface (16b) capable of engaging in the mandrel (20) of the wiping reel (B). Said bearing surface (16b) is extended on one side by a flange (16c) constituting an abutment face of the wiping reel (B). In its inner part, the reel holder (16) is arranged with a sleeve (16a) of great length greater than that of the seat (17b) with, at the end, an annular narrowing (16d). The reel holder (16) thus allows the centering and positioning of the reel (B), which rests on the cylindrical surface (16b).
• the coil holder (16) internally forms, between its outer cylindrical seat (16b) and the inner sleeve (16a), an inner chamber (16e) allowing the engagement and fixing of a flat spiral spring (21).
• One end (21a) of the latter is shaped in the form of a hook to engage in a slot (16f) forming a housing established on the peripheral wall of said bearing surface (16b).
• the other end (21b) of the spring (21) also forms a hook and is fixed on a finger (22) projecting from the flange (17a) of the support piece (17).
• the reel holder (16) is thus mounted to rotate freely on the aforementioned fixed support part (17).
• the friction means (24) can be established by a multitude of projections formed directly on the spool holder (16) during its molding.
• the friction means (24) consists of a tongue (24a) established transversely on the cylindrical surface (16b) of the reel holder (16). This tongue is produced between two slots (24b) established over a part of the width of the seat (16b) giving said tongue a certain elasticity of movement, in order to ensure its contact with the mandrel (20) of the coil (B ).
• the latter is arranged with a projecting lug (25) disposed adjacent and parallel to the bearing cylindrical (17b) of the support part.
• the reel holder (16) has in turn, towards the inner part forming the sleeve, a boss (16h) projecting forming a stop on the lug (25) and thus limiting the rotation of the reel holder on the support part (17 ).
• a complementary end piece (26) is disposed at the front of the reel holder, a complementary end piece (26) capable of engaging on the mandrel (20) of the reel of wiping material by its front face.
• This end piece (26) made in one piece, has a conical shape internally (26a) extending by a cylindrical seat (26b) inside capable of bearing on the front part of the sleeve (16a) of the spool holder (16) and against the locking finger (19) associated with the support part (17) of the spool holder.
• the abovementioned abutment means make it possible to limit the tensioning of the spring over a revolution. In the event of continued traction on the strip of material, there occurs a phenomenon of sliding of the mandrel on the spool holder and therefore on the tongue.
• the strip of material may, at the end of traction and cutting, present a loop (short broken lines). stopping of the stress of this traction allows the reel holder, under the effect of relaxation and elastic return of the spring, a rotation in the opposite direction of said reel holder, with the automatic removal of the loop.
• FIG. 1 shows, in addition, a support hub
• the constant tensioning of the paper strip is also emphasized, thanks to the return effect obtained after each pull.
• the reel holder is advantageously made in a single piece of plastic. It is the same for the support part of said reel holder.
• the assembly of these components is quick.
• the fixed support part (17) can be molded directly with the bottom wall (2a) of the casing, so that in this implementation, there is only one plastic insert left, know the spool pin. It is necessary to add the above-mentioned spring (21).
