Definitions

• the invention relates to the technical sector of dispensing devices for wiping materials of the hooded paper type or similar for wiping hands, toilet paper, the strip of material can be in the folded or unfolded position.
• the Applicant has developed numerous dispensing devices of this type in automatic or semi-automatic dispensing versions.
• the dispensing devices are of the type comprising a casing (1) capable of pivotally receiving a cover (3).
• the housing receives flanges (2) supporting a reel holder (4) of wiping material in its upper part.
• a drum (5) is mounted to rotate freely with said flanges and is arranged to receive the cutting device (6).
• the drum can be arranged at one of its ends with an eccentric (7) associated with a launching and return spring (8), one end (8a) of which is fixed to a finger (7a) associated with the eccentric and the other end (8b) to a fixed part of one of the lateral flanges (2) of the casing.
• the other end of the drum is associated with an operating button (9) which allows the loading of the dispensing device.
• the reel of material is supported on the periphery of the drum.
• the pull of the strip of material by the user can be carried out in a more or less powerful manner which can lead, in the absence of any blocking means, to an unexpected unwinding of several strips of material.
• the Applicant has thus developed an arming mechanism for the device including a parachute system with ratchet, spring and axis, flyweight, axis and fixing member which have been defined in particular in French patent 87 14068.
• the number of parts is therefore significant, in particular with high mold costs with regard to the shapes and profile of the parachute, counterweight and ratchet.
• the assembly is relatively long and not always practical for uninitiated people.
• the Applicant's approach was therefore oriented with a view to simplifying the control mechanism and limiting the rotation of the drum by limiting the number of parts and components necessary to perform the above-mentioned functions.
• Another object sought by the Applicant was to ensure a simplification of assembly of the device by replacing parts and components of the prior art.
• the device for controlling and limiting the rotation of the drum in a device for dispensing wiping materials of the type comprising a casing, a cover, the casing having flanges supporting a reel holder , a drum with cutting device, the drum including at one of its ends an eccentric associated with a launching and return spring the other end being associated with a handwheel, is remarkable in that it is constituted by a single component which is arranged and profiled in the form of an irregular crown to provide the various functions for controlling and limiting the rotation of the drum when cutting a strip of material, said component being in the form of a flat part and having an external profile combining non-regular and successive curvilinear, rectilinear shapes, with projecting zones, and in that said component is fixed on one of the flanges side of the drum in a free and floating mounting, and being capable of moving according to the conditions of rotation of the drum, in normal or accelerated rotation to ensure the effects of the stop and control.
• FIG. 1 is a view of a first side of the dispensing apparatus.
• - Figure 2 is a view of a second side of the dispensing device including the device of the invention in the rest or non-return position and ensuring the exit of a regular size of the strip.
• - Figure 3 is a side view according to Figure 2 in the drum cutting position and showing the orientation of the device of the invention.
• FIG. 4 is a side view according to Figures 2 and 3 illustrating the drum in the end of cutting position and showing the orientation of the device of the invention.
• - Figure 5 is a partial perspective view and before mounting of the device of the invention on the drum.
• - Figure 6 is a side view according to Figures 2 and 3 illustrating in particular the position of the drum and the associated component in the event of very strong traction on the paper strip, as a stop.
• - Figure 7 is a side view according to Figures 2 and 3 illustrating the position of the drum and the component in the event of reverse operation on the operation button and stop in non-return position.
• FIG. 8 is a side view according to Figures 2 and 3 showing a guide stop of the device of the invention.
• the dispensing apparatus comprises the elements described above.
• the device according to the invention is referenced as a whole by (10). It consists of a single component which is arranged and shaped in the form of an irregular crown to provide the various functions for controlling and limiting the rotation of the drum (5) when cutting a strip of material.
• This component is in the form of a flat part which may be made of a plastic material, a rigid elastomer or the like of polyurethane for example and of a thickness which may be of the order of approximately 3 to 10 mm.
• This component has an external profile combining non-regular and successive curvilinear, rectilinear shapes, with projecting zones whose functions will appear subsequently.
• This component has in its central part a cutout (10a) substantially ovoid to surround the axis (5a) of rotation of the drum (5) and any shape established on one of the lateral flanges (5b) of the drum located in opposition to the mechanism of launching and elastic return (7-8) of the drum which appears in FIG. 1 of the drawings.
• said component (10) object of the invention is located to be positioned relative to the second side flange of the drum opposite the launching and return mechanism (7-8) above.
• the lateral flange (5b) of the drum (5) thus has two projecting fingers (5c-5d) arranged not diametrically to the axis of the drum, but with an offset represented by the line XO Y.
• These two projecting fingers are susceptible authorize the positioning or centering of the component, which is arranged in its thickness with two profiled openings (10b-10c) allowing the stabilization of the component on the aforementioned projecting fingers.
• These two cutouts have a substantially bean shape, each defining two consecutive zones (10bl-10b2; 10cl-10c2), with an intermediate constriction (lOd), capable of allowing the respective positioning of said projecting fingers formed on the flange of the drum, as a function of the rotation of the drum and of the said component associated with it.
• Around the openings is formed a profiled recess (10th) authorizing the positioning of a connecting washer (11) engaging and fixing on said fingers while allowing free and floating mounting of the component, as will appear in the continuation of the description.
• the outer periphery of the crown-shaped component successively comprises four zones, namely:
• This fourth projecting zone (10-4) has on either side in connection with the first and third zones of the rectilinear faces (10g-10h) forming stops and whose respective functions are as follows: the stop (10g) acts as a parachute stopper with reference to Figure 6 of the drawings. This situation corresponds to a very strong pull on the strip of paper.
• the stopper (10h) is used to limit the unloading of the device in the event of reverse rotation of the operating button as shown in Figure 7.
• the central opening (10a) formed on the component forming the crown is disposed substantially offset from its central point so as to differentiate the volumes of the first and third zones by creating a kind of unbalance which will allow during the rotation of the drum the natural tilting of the component for the desired functions.
• Figure 2 which corresponds to the rest position of the drum, the component freely attached to the side flange of the drum is in a low position relative to the axis of the drum and the fingers.
• This position is substantially vertical if we consider the position of the second and fourth projecting zones established on the periphery of the component. The latter is held by the projecting fingers which are in the openings formed in its thickness and in particular in the areas (l ⁇ bl) and (l ⁇ cl).
• the second zone forming spout and stop (10f) is in contact with the fixed stop (12) established on the casing, so that it is impossible for the operator to rotate the drum back and the paper exit is obtained according to a dimension determined for subsequent gripping by the user.
• the drum has rotated according to arrow (F) under the effect of traction of an outgoing strip of paper by the user.
• This rotation of the drum causes the component (10) associated with it to rotate, but the latter remains in the initial position through its passage openings (lObl) and (lOcl) in the fingers (5c) and (5d) thanks to the retention throttle profiles (10d) of the corresponding openings.
• the fourth protruding zone passes above the stop formed on the casing.
• the component (10) finds itself in a substantially vertical position and its cutouts (10b) and (10c) oriented towards the bottom allow the descent by gravity of said component which thus passes from the first zones (lObl) and (lOcl) to the second zones (10b2) and (10c2) established in said cutouts.
• the tilting is effected by the existing unbalance.
• FIG. 6 which corresponds to the position of the drum and of the component during very heavy use of the user on the paper strip, said component remains in the high position on the finger due to the very rapid rotation of the drum.
• the component comes through the projection (10g) in abutment on the fixed stop (12) of the casing.
• the drum then returns back under the return action of the launching spring (8) until the stop (10f) comes to its turn by the rotation of the drum in contact with the fixed stop (12) formed on the casing.
• the component is tilted on the projecting fingers, thus allowing the contact of the stop (10f) on the fixed stop (12).
• this relates to the function of the stop part (10h).
• the operator has maneuvered the operating button conversely (9) causing the rotation of the drum in the wrong direction.
• the stop (10h) then comes against the fixed stop (12) blocking the operation of the device. It is therefore necessary to redo another correct maneuver this time.
• the device comprises a profiled fixed stop (13) for deflection, directly formed or attached with the corresponding wall of the casing in its upper part.
• This fixed stop (13) returns the projection (10.4) of the component in the event of strong traction of the strip of material to allow the vertical lowering of the component (10).
• the latter emerges from its high position and the positioning axes thanks to the passage openings (10bl) (10b2) by moving towards the axis of the drum.
• the part (10f) of the component comes into contact with the non-return stop (12) formed in the lower part of the casing.
• the device comprises an additional pressure roller mounted between the flanges of the casing and bearing on the drum.
• the shape given to the component and its distribution of material and volume makes it possible to obtain an unbalance which has two functions.
• the component falls by its own weight and is only used by the stop (10f) for the non-return and paper output function of the device.
• the imbalance causes the component to spread and tilt by centrifugal force, so that the abutment face (10g) comes into contact with the fixed abutment (12) to constitute the stop.
