Definitions
- the invention relates to a key intended for mechanically actuating a lock, comprising a metal pin having a longitudinal axis, and a plastic shell rigidly connected to one end of said pin.
- Such keys are well known in the automotive field, where increasingly use keys with integrated remote control allowing the user to unlock their vehicle by pressing simply the plastic shell of his key to emit an infrared signal towards his vehicle.
- the electronic circuit of the remote control is generally placed in the plastic shell, so that the space remaining for the mechanical connection between the spindle and the shell is very small.
- the realization of a rigid and reliable assembly for a low cost is difficult to achieve.
- the plastic shell of such a key it is conventional for the plastic shell of such a key to consist of two complementary half-shells between which the spindle is taken sandwich. These half-shells generally have symmetrical shapes and which carry out a blocking of the brooch.
- the defect of such an assembly is that it resists poorly the torque of twist which is applied to the shell by the spindle when opening a lock. Ultimately, this torque tends to open the two half-shells, rendering the key unusable.
- One way to solve this problem consists in screwing the spindle on one of the half-shells, thus, the couple of torsion is fully taken up by only one of the half-shells and does not tend to separate them from each other.
- the defect of this solution is to weigh down the manufacturing range of the key, and therefore increase its manufacturing cost.
- the object of the invention is to remedy these drawbacks.
- the invention relates to a key intended to actuate mechanically a lock, comprising a metal pin having a longitudinal axis, and a plastic shell rigidly linked to a end of said spindle, characterized in that said shell has a half-shell lower which is linked to the spindle by a sliding link according to said longitudinal axis, and an upper half-shell which is rigidly linked to the lower half-shell and which includes a stud perpendicular to the axis longitudinal, coming to be lodged in a corresponding hole of said spindle to prevent any translational movement between the spindle and the shell along said longitudinal axis.
- Such a construction means that the lower half-shell takes up most of of the forces applied to it by the spindle, and in particular the torque of torsion that appears when opening a lock, without adding a screw or any additional part, which reduces the cost of manufacturing such a key.
- the mechanical connection between the spindle and the lower half-shell blocks five of the six degrees of freedom, the only remaining degree of freedom being a translation of the spindle relative to the shell along the longitudinal axis.
- all the forces applied by the spindle to the shell except for one lifting force along the longitudinal axis are taken up by the half-shell lower alone.
- a stud of the upper half-shell is housed in a corresponding hole in the end of the spindle to block said translation along the longitudinal axis and resume said tearing force.
- the stud of the half-shell upper has a cross-shaped section intended to facilitate its insertion in the corresponding hole of the end of the spindle and simplify the manufacturing process of said upper half-shell, which can be obtained by molding.
- the upper half-shell comprises two blades which are parallel to the stud and parallel to the longitudinal axis, and which fit into corresponding lateral recesses of the spindle to complete the stud in the resumption of the pull-out forces applied by the pin to the shell along the longitudinal axis.
- FIG. 1 we see in perspective an assembled key which is intended for mechanically actuating a lock.
- This key has a metal pin 1 having a longitudinal axis 2, and a shell of material plastic 3 rigidly connected to one end of said pin.
- the shell comprises a lower half-shell 4 having the shape of a shell, into which one end of the pin is inserted metallic at a slide link 5, along the longitudinal axis 2, as well as an upper half-shell 6 also having the shape of a shell, which is rigidly linked to the lower half-shell.
- the assembly thus constituted is a rigid assembly of the plastic shell with the pin.
- Figure 2 which is a sectional view along a plane comprising the longitudinal axis of the spindle, of the assembled key, we see a spindle whose the section view is a rectangle having one end on either side of which are located the lower half-shell 4 and the half-shell upper 6.
- the shape of the case 5 which is part integral with the half-shell 4 is complementary to the shape of the end bottom of the spindle.
- the shape inside of the connection box which is a parallelepiped is represented by a rectangle having one of its sides not shown, this side corresponding to the open face to receive the end of the pin of said parallelepiped.
- a stud 7 having an axis perpendicular to the longitudinal axis, which is part of the upper half-shell and which comes fit into a corresponding hole 8 in the end of the spindle.
- another hole 9 has been made in the upper face of the housing 5.
- a space vacuum E Near the housing, inside the half-shells is a space vacuum E, which is intended to receive the electronic box of a remote control infrared intended to allow the remote opening of a system of locking.
- This rigid assembly is constituted by a lip "Male” 10 which comprises the lower half-shell, and which is inserted in a “female” channel 11 of complementary shape that includes the upper half-shell.
- FIG. 3 which is a perspective view of the three components of the key to assemble, brings up a pin which is arranged opposite the housing 5 of a lower half-shell, this lower half-shell being at side of an upper half-shell, so that by inserting the pin according to the arrow F1 in the housing 5 and closing the upper half-shell on the lower half-shell, as indicated by the arrows F2 and F3, we obtain the assembled key as shown in Figure 1.
- FIG. 2 makes it possible to note that the male lip 10 of the lower half-shell extends so around the perimeter of the surface upper of the lower half-shell.
- the half-shell superior to a channel 11 which extends along the periphery of the face corresponding of the upper half-shell to receive the male lip 10 in order to carry out the assembly by clipping of the two half-shells.
- the positioning pad 7 has a cross-shaped section which is intended to be inserted into a corresponding hole 8 at the end of the spindle.
- This section is cross-shaped to facilitate the molding operation in this sense that the thickness of the branches of said cross is close to the thickness of the shell itself, in order to avoid problems of molding linked to an excess thickness of the stud.
- this shaped section cross facilitates the positioning of the stud relative to the corresponding hole 8 from the end of the spindle, to overcome problems related to geometric manufacturing dispersions.
- blades L1 and L2 of rectangular shape which are arranged parallel to an axis of symmetry A7 of the positioning pad 7, and to the longitudinal axis 2. These blades which are intended to fit into corresponding recesses E1 and E2 of the end of the spindle have the role of completing the stud in the resumption of the tearing forces applied by the spindle to the hull especially when the user removes the key from a lock.
- the upper face of said housing comprises a central hole intended to receive the stud of the upper half-shell as well as two slots which are arranged parallel to the longitudinal axis 2 which are positioned to receive the blades L1 and L2 so that they come to be embedded in the recesses correspondents E1 and E2 of pin 1, so as to take up efforts tearing.
