Definitions

  • the present invention relates to a housing comprising a body housing and a pivoting cover, and more particularly but not exclusively a case intended to contain a makeup product.
  • the means used to assist the opening movement of the cover in these known cases do not offer complete satisfaction, especially in terms of production cost and reliability.
  • the invention therefore relates to a new housing comprising a housing body and a pivoting cover, which is characterized by the fact that it comprises at least one elastically deformable member, attached on the one hand to one of the body of the housing or of the cover and rotatably mounted on the other hand in a housing on the other side of the body housing or cover, this housing being eccentric relative to the geometric axis of rotation of the cover so that said organ undergoes a bending stress varying with the opening angle of the cover and restores, from a predetermined stroke of pivoting of the cover from the closed position to the position of energy accumulated by elastic deformation in creating a couple tending to assist the opening movement of the cover.
  • the housing comprises a single elastically member deformable and a hinge to impose a geometric axis of fixed rotation, around which the pivoting of the lid.
  • the housing has two bodies elastically deformable constituting pivots used for articulation of the cover. In this case, an additional hinge imposing a geometric axis of rotation is not necessary.
  • the first elastically deformable member is rotatably mounted in a first housing
  • the second member resiliently deformable is rotatably mounted in a second housing
  • the axis geometric of rotation of the cover being located substantially at mid-distance axes of the two housings.
  • the organ or organs assisting the movement opening the lid go through a state of maximum stress when the cover is in an intermediate position between its open position and its closed position, so as to restore, from a predetermined cover pivoting stroke from the open position to the closed position, from the energy accumulated by elastic deformation creating a couple tending to assist the closing movement of the cover.
  • the housing has two elastically deformable members serving as pivots, these are preferably made by conformation of the same metal wire.
  • this wire is shaped according to a rectangular frame, one of the short sides of this frame being open to form the two pivots, between which is an extension of the cover.
  • FIG. 1 shows schematically a case 1, comprising a case body 2, a pivoting cover 3 from front to back and a receptacle 4 intended to be placed in the housing body 2, this receptacle 4 having a first housing 5 intended to contain the makeup product, for example a eyeshadow, and a second housing 6 to accommodate an applicator, not shown.
  • the cover 3 is retained on the housing body 2 by a metal frame 7, of substantially rectangular shape, produced by conformation of a circular section wire made of spring steel.
  • This frame 7 The two long sides 14,15 of this frame 7 are joined at the front by a short side 16, the other short side being open at mid-length to form two pivots 9, 10.
  • pivots 9 and 10 are inserted at their free end in housings constituted by respective blind holes 11 and 12 produced on the opposite faces of an extension 13 of the cover 3, projecting beneath its underside 24, substantially mid-width cover 3.
  • the housing body 2 is hollowed out at the rear to accommodate the extension 13 and do not hinder the closing movement of the cover 3.
  • the receptacle 4 has a corresponding cutout 17 at the rear.
  • the long sides 14,15 and the short side 16 of the frame 7 are housed in a groove 18 of the housing body 2, formed between its wall outer 19 and an inner rib 20, parallel thereto.
  • the groove 18 is closed at the top by the receptacle 4 when the latter is fixed to the housing body 2.
  • the short side 16 then extends substantially parallel to the geometric pivot axis of the cover and the long sides 14, 15 substantially perpendicular to this axis.
  • the short side 16 can be fixed in the middle, for example in the bottom of the groove 18 by any appropriate means.
  • the height of the groove 18 is chosen so as to allow a certain angular movement of the long sides 14, 15 of the frame 7, around the axis of the short side 16, as will be explained later.
  • the housings 11 and 12 are offset from the axis instantaneous geometric rotation of the cover 3.
  • the housing 11 is further from the front free edge 23 of the cover than is the housing 12 so that during the introduction of the ends of the frame in these housings 11 and 12, the end which constitutes the pivot 9 is stressed in bending towards the outside of the frame 7, while the other end constituting the pivot 10 is stressed inward bending.
  • the housing 11 is also closer to the inner face 24 of the cover 3 than is the housing 12, so that the setting place of the ends of the frame in the housings 11 and 12 is accompanied a slight deformation of the long sides 14, 15 of the frame 7 around the short side axis 16.
  • the long sides 14 and 15 remain substantially straight and contained in parallel planes, substantially perpendicular to the axis geometric rotation of the cover 3 while the short side 16 is slightly deforms in torsion around its axis.
  • the pivoting movement of the cover 3 also causes the gradual lowering of the long side 14 of the frame 7 and the raising of the long side 15, until the latter are, for a given pivot angle i o , coplanar, as shown in FIG. 6, this angle i o being equal to approximately 45 ° in the embodiment described.
  • the cover 3 can thus keep the position in which it is left by the user, due to the friction between pivots 9 and 10 and housings 11 and 12.
  • pivot 9 When closing the cover from the position opening, pivot 9 is constrained in bending towards the outside while the pivot 10 is constrained inward bending, until reaching the position of maximum stress corresponding to Figure 10.
  • the pivots 9 and 10 thus exert on the cover 3, during its closing movement from the fully open position to the opening angle i o , a restoring torque which must be overcome by the user moving the cover 3 .
  • the pivot 9 can deform inward and restore the accumulated elastic energy, while the pivot 10 can deform outward to also restore the elastic energy accumulated.
  • the pivots 9 and 10 thus exercise during the continuation of the movement closing a motor torque assisting the movement of the cover.
  • the frame 7 ensures the keeping the cover in its closed position, so that it it is not necessary to use a clasp.
  • the ends of the frame 7 serving as pivots 9 and 10 can be constrained when the cover is in its closed position and exert on the latter a couple tending to move it to its open position.
  • the cover 3 must in this case be kept in its closed position by a clasp.
  • the small side 16 of the frame can advantageously be shaped to constitute all or part of this clasp.
  • the cover is hinged directly on the ends of the frame 7 but alternatively, one can provide a hinge imposing the rotation of the cover around a predetermined and fixed geometric axis of rotation, distinct from one to less of the axes of the housings 11 and 12.
