Definitions

  • the present invention relates generally to a toothed key such as that used in locks or anti-theft devices for motor vehicles.
  • Such a key is represented for example in document DE-B-25 16 340.
  • the present invention relates more particularly to keys whose teeth are formed on the lateral faces of a plate constituting the key rod so that the teeth obtained do not touch the outer edges of the plate, this in order to avoid sharp edges which can be unpleasant to the touch by the user, or even damage the user's pockets.
  • Such teeth are generally obtained by milling the lateral faces of the plate, which requires specialized machines performing complex and delicate operations, hence a high cost for the entire key.
  • a toothed key in particular for a lock or anti-theft device for a motor vehicle, comprising a key body in which is formed an opening for receiving a key profile provided with two series of stepped notches constituting the toothing of the key, characterized in that the key profile consists of a core horizontal connecting to two vertical wings at the ends of which are arranged the series of stepped notches, said vertical wings being symmetrical and offset with respect to the longitudinal axis of the key profile and in that the key body comprises lateral faces on which Are provided, at the opening, symmetrical recesses with respect to the longitudinal axis of the key body, said recesses serving to accommodate the wings carrying the series of stepped notches.
  • the stepped notches are no longer obtained by a milling operation but by a turning operation which is much faster and requires less complex and therefore less expensive machines.
  • FIGS. 1 to 4 and 7 illustrate a key body 10 consisting of a plate of generally parallelepiped shape.
  • the rear end 12 of the plate located on the right in FIGS. 1,4 and 7, is full and intended to be connected to a key head (not shown) for example by riveting or overmolding.
  • the front end 14 of the plate located on the left in the same figures, is bevelled so as to facilitate the introduction of the key into the barrel, for example of the lock, with which it is intended to cooperate.
  • the key body 10 comprises, along its longitudinal axis X-X, an opening 16 generally in the shape of a T, the branches 18 of the T being situated on the rear end side 12.
  • the key body 10 has lateral faces 20,22 on which recesses 24,26 respectively are provided.
  • recesses 24, 26 are located on the front part of the key (on the left in the figures).
  • the recess 24 is located in the lower part of the key body 10 and opens into the opening 16, while the recess 26 is located in the upper part of the key body 10 and also opens into the opening 16, otherwise says the recesses 24 and 26 are symmetrical with respect to the axis XX.
  • the key body 10 comprises, on each of its lateral faces 20, 22, a longitudinal groove respectively 28.30 eccentric with respect to the axis XX and symmetrical with respect to said axis as can be see it in particular in Figure 3.
  • Each longitudinal groove 28.30 opens out, on the one hand, on the front end 14, and, on the other hand, in the opening 16. It will be noted that one of the longitudinal faces 28 ', 30' of each grooves 28.30 is in extension with one of the longitudinal faces 32.34 of the opening 16.
  • FIGS. 5, 6 and 7 illustrate a key profile 40.
  • the section of the key profile 40 is constituted by a horizontal core 42 connecting to two vertical wings 44,46 symmetrical with respect to the axis Y-Y.
  • the wings 44,46 have internal faces 58,60 respectively which are coplanar, that is to say that they extend along the same vertical axis on either side of the core 42.
  • the vertical wings 44,46 comprise, on their longitudinal end face, a series of stepped notches respectively 48,48 'extending from the front end 52 over a length L corresponding to the length L of the recesses 24 and 26 of the key body 10.
  • the shape and the height of the stepped notches 48, 48 ′ are symmetrical with respect to the axis Y-Y, said stepped notches thus forming the toothing of the key.
  • the key profile section makes it possible to develop this toothing by a simple turning operation and no longer milling as for the keys of the prior art. It can thus be noted in particular (FIG. 6) that the notches 48, 48 'have in section a curved outer face 50, 50'.
  • the rear end of the key profile is in the form of a tenon 54 connected to the notches 48, 48 ′ by a groove 56.
  • the key profile 40 fitted with its notches 48, 48 ' is introduced horizontally into the opening 16 of the key body 10, then by applying a rotation movement, the internal faces 58 are applied. , 60 of the vertical wings 44, 46 respectively on the lateral faces 22, 20 of the key body 10.
  • the wings 44, 46 of the key profile carrying the series of notches 48, 48 ′ over a length L are received in the recesses 26, 24 made in the key body 10.
  • the lug 54 is provided with elastic tabs 62 which snap into the branches 18 of the opening 16 of the key body 10.
  • the final connection of the key body 10 and the key profile 40 can be carried out for example by overmolding a key head (not shown).
  • E denotes the width of the opening 16 and e the width of the grooves 28.30, the width of the core 42 of the key profile 40 will be equal to E - 2e.
  • the front end 14 of the plate can be non-bevelled and have an entry face in the lock which is vertical, similarly the pre-assembly between the key body 10 and the key profile 40 can be carried out by deformation of metal instead of latching by legs without thereby departing from the present invention as defined by the claims.
