Definitions
- the present invention relates to a lipstick mechanism or the like, of the type comprising an internal tubular sheath intended to rotate in one. external tubular sheath, the sheaths having two longitudinal slots and two helical slots making it possible to guide in translation the pins of a grape-carrying bucket disposed in the internal tubular sheath, the internal sheath comprising reliefs of f at a cylindrical base einage intended to rest elastically on a cylindrical bearing linked to the external sheath, in order to obtain a soft and regular rotational movement between the two sheaths.
- a mechanism is injection molded from plastic.
- braking reliefs are then formed by pads or buttons arranged on a wall part, thinned or not, taken in the wall of the cylindrical base and cut (molding) to form the tongue. This is shown by various forms of tabs, for example the US patents 5186560, 5186561 or 5324126.
- the object of the invention is to propose a new braking mechanism which achieves the same quality as that proposed in patent EP 0 439 381, but is of a lower cost.
- a lipstick mechanism or the like of the type comprising an internal tubular sheath intended to rotate in an external tubular sheath, the sheaths having two longitudinal slots and two helical slots making it possible to guide in translation of the nipples of a grape-holder bucket disposed in the internal tubular sheath, the internal sheath comprising a cylindrical base with a braking relief intended to bear elastically on a substantially cylindrical bearing surface linked to the external sheath, characterized in that the bearing surface linked to the external sheath is elastically deformable and in that the braking relief is constituted by a raised zone which sinks into said bearing surface.
- the term “raised zone” means a zone whose distance from the axis of rotation is greater than the outside radius of the relief portion of said cylindrical base of the internal sheath; this height is even here greater than the nominal internal radius of the range of the outer sheath, which causes the abovementioned depression, the depression being considered not as a depression within the wall itself but as a localized deformation of said wall with respect to its natural position.
- the elasticity of the braking is therefore given by the elasticity of the deformation of the wall constituting the bearing surface, and no longer by braking lugs. This simplifies manufacture and eliminates a part of the anterior mechanism, namely the flange of elastic tabs.
- the braking relief concerns a substantial angular sector of the internal sheath (or of the bearing surface), so as to offer a fairly wide surface which makes it possible to reduce the pressure necessary for braking and making it possible to limit the sinking to a very low value.
- the relief is preferably in the form of a raised cylindrical zone and its extension sector is between 70 and 100 ° and preferably between 80 and 90 °.
- the braking relief is formed by a simple shift of the cylindrical portion of the inner sheath, the 'level of the braking range.
- a rigid cylindrical envelope such as the sheath of the mechanism, it is associated externally with a space allowing its deformation, this space being able to be formed at least partially by a thinning of the envelope or by a thinning of the wall constituting the scope, the latter possibility being particularly compatible with the need to make the wall deformable.
- a cylindrical casing at all at this level, for example by planning to make a shorter sheath.
- the mechanism is advantageously made from one or more injected plastics.
- the inner sleeve of the invention can be manufactured in many 'plastics traditionally used for this type of injection, depending on the quality and price of desired returns. We also take into account the intended applications: we know that depending on certain formulations used for the reasons and the solvents that emanate from them, certain materials are recommended rather than others. For example, some solvents react with styrenic resins like polystyrene and others cause swelling
- polypropylene which is detrimental to the maintenance over time of the braking qualities of the mechanism of the invention, since these qualities are essentially linked to relatively precise clearances provided between all the constituent elements.
- a polyacetal resin polyoxymethylene POM. This resin is particularly advantageous • due to its good shape memory and its resistance to cracking; on the other hand, the polystyrene-polyacetal couple or the polypropylene-polyacetal couple offers a good quality of friction.
- the inner and outer sheaths have contacts limited to two narrow support zones, preferably located towards their respective ends.
- the internal sheath is provided perfectly cylindrical, and the external sheath is provided with a very slight taper, invisible to the eye, but sufficient to facilitate one. good release; the internal sheath has at its lower part a cylindrical bearing surface of very small thickness (of the order of 10 e of mm) sufficient to ensure perfect coaxial maintenance of the external sheath bearing on the one hand on the upper part of the sheath inner and secondly on said span of the lower part of the inner sheath.
- This support in two distant narrow zones makes it possible to considerably reduce the friction of the outer sheath ' on the inner sheath. Most of the friction is due to the cam formed by the braking relief according to the invention.
- This relief can itself advantageously be provided with a certain taper, depending on the tightening torque that is desired; in fact, this conicity makes it possible to adapt the braking surface and therefore the pressure exerted for the desired application.
- FIG. 1 is a half side view and a half sectional view of a mechanism lipstick according to the invention.
- FIG. 1 is a detail sectional view of the friction part of the mechanism of Figure 1.
- FIG. 3 is a simplified detail sectional view of a variant of the friction part of the mechanism of Figure 1.
- Figure 4 is a cross-sectional view of the friction part of the mechanism of Figure 1. -
- FIG. 5 is an exploded view of the various elements constituting the mechanism of Figure 1.
- FIG. 6 and 7 are two diagrams of cross section of the outer cylindrical surface of the sheath at the friction part.
- a lipstick mechanism conventionally comprises (FIG. 5) a cylindrical internal sheath 1 made of plastic receiving the grape-holding bucket 2.
- the external sheath or spiral 3 also made of plastic, substantially cylindrical, is threaded on the whole, itself coated with a sheath decorative or body 4 generally made of metal or metallized plastic. These elements are mounted concentrically, in symmetry of revolution around an axis XX.
- the internal sheath 1 comprises two longitudinal slots 10 and 11, while the external sheath 3 comprises two helical slots 5 (which may be only simple grooves on its substantially cylindrical inner face) defining with the longitudinal slots 10, 11 an area where the pins 6 of bucket 2 engage, the height of this zone (and therefore the position of bucket 2) depending on the relative rotation of the sheaths l and 3.
- the outer sheath 3 has at its base a substantially cylindrical zone 7 which is intended to come in front of the annular base 12 of the inner sheath 1 so as to cooperate with it to produce the soft friction device which will be described later.
- the internal sheath 1 has three zones, respectively from top to bottom, the main zone 13 on which the slots 10, 11 are formed; then the base annular zone 12 on which the eccentric braking device of the invention is formed, finally the base 14, which can include longitudinal grooves or flutes 19 on a part, preferably lower, of its outer cylindrical surface. Zones 13 and 12, as well as 12 and 14, can be separated by shoulders 17 and 18.
- the base annular zone 12 is constituted by a generally substantially cylindrical wall, the internal face of which is in continuity with the internal faces of the zone 13 and of the zone 14 (cf. FIG. 2).
- the outer face 20 of the wall 12 has a significant angular sector A, a braking gentle relief 21 designed to cooperate with the inner wall '22 of the lower portion 7 of the sheath 3.
- This relief soft 21 is generally constituted by a cylindrical surface with generator parallel to the axis XX. It may be, as shown schematically in Figure 6, to provide on the cylindrical outer surface 20 of the wall 12, centered on XX, an excess thickness located in the sector A, this excess thickness being analogous to a cam. It can also be, as shown schematically in Figure ' 7,.
- the eccentricity d (for example 0.2 mm) between the two axes means that the part 21 will constitute a relief of approximately the same value d at its maximum level with respect to the theoretical cylindrical surface 20 ′ which would be centered on XX, while the opposite part of the outer surface 20 will be set back from the same clearance d with respect to the theoretical surface 20 '.
- a relief 21 is obtained having a maximum excess thickness h relative to the theoretical cylinder. This height h is equal to the offset d in the case of FIG. 7.
- This raised part 21, whether it results from a true relief or from an eccentricity, will therefore press on the face 22 of the wall 7 on an angular sector A which, according to the invention, is chosen to be sufficiently large. It is preferably between 70 ° and 100 °, and more particularly between 80 ° and 90 °.
- the wall 7 is designed so as to be able to deform on passage of the raised part 21, thanks to its dimensional and constitutive characteristics: a given plastic material having a certain flexibility and a thickness thin enough to benefit from this flexibility; for example, in the case of a polyacetal resin, a thickness of approximately 0.5 mm can be envisaged.
- a sufficient space 25 in principle slightly greater than the maximum allowance h of the relief 21.
- This space 25 can be obtained either by an internal thinning of the body 4 in its lower part (or a clearance without thinning of the said body, by increasing the average diameter of the body), as shown in FIG.
- Figure 4 illustrates the deformation occurring at the wall 7 of the spiral 3 and the wall 12 of the inner sheath.
- the body 4 is rigid and remains a cylinder centered on XX.
- the wall 12 of the internal sheath 1, centered on OO (we are in the case where the relief 21 is formed by offset) pushes by its part 21 against the opposite face 22 of the wall 7, which, in principle cylindrical centered on XX, is then deformed into an egg, and locally approaches the wall of the body 4; diametrically opposite, the part 20 of the wall 12 remains distant from the wall 7 which itself remains at a distance from the body 4.
- the height in contact of zone 12 and zone 7 on which the deformation takes place is of the order of 2 to 3 mm.
- the outer sheath 3 described as substantially cylindrical, is preferably endowed with a very slight conicity resulting in a difference of a few hundredths of a millimeter between its smallest diameter at the top and its widest diameter at the bottom.
- Its upper part is supported directly on the external face of the internal sheath 1, just below the edge 15, while its lower part is supported on a shoulder of very small thickness (for example 1/10 e of mm ) formed in the lower part of the zone 13 of the sheath 1, just above the annular zone 12.
- the external sheath 3 is in coaxial support on the internal sheath 1 only on two zones formed almost reduced to circles respectively high and low, and the friction generated during their relative rotation is minimum.
- the surface with said braking cam 21 of a certain taper (widening downwards) so as to adapt, depending on the application, the contact surface of this zone 21 and of the lower zone 7; the more or less taper adopted will determine, in conjunction with the other parameters such as the height and extension of the surface 21, the braking force exerted.
