Definitions

  • the present invention relates to a locking / unlocking device in translation of an extension relative to a piece of furniture such as a bed or a chair, such a device being known from document US-A-4,135,835.
  • Beds available on the market, especially those fitted hospitals, are equipped with a frame supporting the box spring which is provided with an extension sliding. This allows to give the bed a length adaptable to the size of the person occupying this bed.
  • the extension has two longitudinal sections and parallel which can slide on rods integral with the bed.
  • the profiles have each a transverse hole while the rods each have a series of holes similar so that the profiles can be arranged relative to the rods so to match the holes together and allow the introduction of means of locking, that is to say of locking in translation of the extension.
  • This type of equipment is also found on certain armchairs, for the positioning and adjustment of a cushion acting as leg support.
  • the locking means most often include springs, pawls or other mechanical parts to push in or move.
  • locking / unlocking mechanisms implement several mechanical parts liable to jam or break and the actuation of which may cause certain incidents, including pinching of fingers. Moreover, the locking / unlocking operation requires a certain dexterity and, for the operator, understanding the gesture to be made is not always easy.
  • the object of the present invention is to provide a locking device / efficient unlocking with a minimum number of mechanical parts, whose actuation is easy, fast and without risk of incidents, especially jamming fingers.
  • This locking / unlocking device in translation of an extension with respect to a piece of furniture is characterized in that that the locking means consist of an elastically deformable wire stirrup, general shape of "U”, whose free ends are folded down to be able to penetrate in the holes and in that there is provided on each of the profiles of the ramp means which cooperate with a lateral branch of the U-shaped stirrup, and which are shaped in such a way so that an effort on the stirrup tending to rotate it around the axis materialized by the folded ends causes a deformation of the stirrup which brings out the folded ends of one of the holes and, consequently, the unlocking of the extension, while a relaxation of this effort causes the reverse movement, that is to say the introduction of the folded ends into said hole and the locking of the extension.
  • the locking means consist of an elastically deformable wire stirrup, general shape of "U”, whose free ends are folded down to be able to penetrate in the holes and in that there is provided on each of the profiles of the ramp means which cooperate with
  • the invention also relates to a piece of furniture comprising a sliding extension fitted with a device conforming to one of the characteristics mentioned above.
  • the bed frame 1 partially shown in Figure 1, has two longitudinal sections 10 formed of metal hollow tubes of square section. Between these profiles are provided two transverse plates 11 and 12.
  • each rod arranged in a vertical plane, is mounted on the internal side of the profiles 10, which means that the two rods 3 face each other. They are made integral with the profiles by means of fastening parts 30.
  • Each rod is pierced with a series of holes 31 with a horizontal axis distributed regularly over the entire length.
  • these holes can be distributed unevenly, so that the extension can be installed in predetermined positions.
  • the extension 2 comprises two longitudinal and parallel sections 20, joined together at one of their ends, by a transverse plate 21.
  • the profiles 20 have a "U" shaped section, the base 202 of which is arranged vertically, that is to say parallel to the rods 3. They are arranged in such a way so that their wings 201 are opposite each other. Profiles 20 can slide along the rods 3, the wings 201 being arranged on either side of the edges lower and upper rods 3.
  • each profile 20 comprises at the base 202, a transverse hole 200 with a horizontal axis.
  • a transverse hole 200 with a horizontal axis.
  • the two sections 20 are provided, on the external face of their base 202, that is to say on their opposite sides, of a part 5, for example in plastic material.
  • this part has two horizontal lower 53 and upper 52 walls which are connected firstly by a curvilinear wall element 54 and secondly by the lateral face 51.
  • an oblong bore 50 is pierced longitudinally, arranged obliquely.
  • the lower part of this hole is disposed on the side of the section 20 and, advantageously, the longitudinal and parallel edges of the bore form an angle ⁇ of approximately 45 ° with the vertical.
  • the locking means consist of a metal wire stirrup 4, general shape of "U”. This stirrup has a base 40 which extends parallel and to near cross member 21 of the extension.
  • the ends of the base 40 are continued by two oblique parts 41 forming an obtuse angle with it. These two parts are each connected to a lateral branch 42 which extends parallel to the profiles 20 and to the rods 3.
  • the ends free 43 of these branches are folded at right angles to be able to penetrate the holes 31 and 200 previously cited, thus realizing the locking of the extension relative to the bed frame (see figure 2).
  • These ends 43 aligned with respect to each other, materialize a pivot axis XX '.
  • the entire stirrup is arranged in the same plane and that the lateral branches 42 pass through the bore 50 provided in each part 5.
  • the parts 41 can form with the branches 42 a certain angle in a vertical plane, so that the base 40 is in a plane different from that ends 43.
  • the base 40 is actuated in the direction of the arrow f (FIGS. 4 and 7A) so as to cause the pivoting movement of the stirrup upwards, around the axis XX 'mentioned above.
  • each lateral branch 42 is forced to move upwards along the bores 50 which act as ramps.
  • the branches 41 and 42 come together under the jamming effect caused by the angle a of each bore (FIG. 7B).
  • the parts 5 are arranged substantially at a third of the distance between the axis XX 'and the part 40 of the stirrup, on the side of the holes 200. This position can vary in depending on the caliper travel desired, the flexibility of the caliper wire and the stroke required to block the extension at the ends 43.
  • This device can, of course, be used for a bed extension, but also for the extension of a leg support, or any piece of furniture having a mobile extension in translation.
