Definitions

  • the present invention relates to a vehicle door handle, in particular for a motor vehicle.
  • the present invention relates to a vehicle door handle comprising a frame connectable to the vehicle door; a rocker arm connected to the frame and rotating, about a first axis, between an open position and a closed position respectively opening and closing a lock on the door; and a retaining body hinged to the frame and rotated, by inertial forces and about a second axis parallel to the first axis, into a retaining position retaining the rocker arm in the closed position.
  • the retaining body is normally defined by a pendulum, which is moved by inertia, upon the vehicle being struck laterally, and in advance of any accidental inertial movement of the rocker arm, into a retaining position preventing any movement of the rocker arm into the open position.
  • the pendulum of known handles of the above type is connected to the frame by a wire torsion spring, which has two portions hinged to the frame, and an intermediate portion supporting the pendulum. More specifically, the intermediate portion of the spring is substantially U-shaped and inserted inside a griplike end of the pendulum; and the spring normally keeps the pendulum in a release position not interfering with the rocker arm.
  • a drawback of known handles of the above type is the weak connection of the pendulum to the frame by the wire spring. That is, the spring is relatively ineffective in keeping the pendulum in a definite axial position, so that the pendulum may be unable to act on the rocker arm when required, in the event permanent deformation of the spring or inevitable in-service vibration causes the pendulum to assume an incorrect axial position.
  • An incorrect axial position of the pendulum may also prevent it from assuming the correct retaining position normally defined by a stop shoulder integral with the frame.
  • the inertial forces on the rocker arm are transmitted to the frame, not directly via the stop shoulder, but via the portions of the spring hinged to the frame, which portions may undergo permanent deformation, thus making the spring ineffective and so preventing any movement of the pendulum.
  • handles wich a frame, a retaining body, rigid pin means, and contrasting elastic means are known from US 3 719 248 A and US 6 007 122 A.
  • the hinge means for the retaining body do not comprise a fork forming pare of the frame, and the elastic means are not carried by rigid pin means interposed between the retaining body and the frame.
  • a handle for a door of a vehicle comprising a frame fittable to the door of said vehicle; a rocker arm connected to said frame and rotating, about a first axis, between an open position and a closed position respectively opening and closing a lock on said door; and a retaining body hinged to said frame by hinge means and rotated, by inertial forces and about a second axis parallel to the first axis, into a retaining position retaining said rocker arm in said closed position; whereby said hinge means comprise a fork forming part of said frame; rigid pin means coaxial with said second axis and interposed between said fork and said retaining body; and contrasting elastic means carried by the rigid said pin means and interposed between said retaining body and said frame to normally keep the retaining body in a position of noninterference with said rocker arm.
  • Number 1 in Figure 1 indicates as a whole a handle for a door 2 of a vehicle (not shown).
  • Handle 1 comprises a frame 3 connected in known manner to an inner surface of door 2 at an opening 2a formed through door 2; and a lever 4 on the outside of an outer surface of door 2.
  • Lever 4 is hinged in known manner at one end (not shown) to frame 3 so as to rotate, with respect to door 2 and when operated by a user, about an axis (not shown) parallel to the Figure 1 plane and to door 2, and between a rest position ( Figure 1) closing a known lock 5 on door 2, and a control position (not shown) opening lock 5.
  • Handle 1 also comprises a rocker arm 6 connected to frame 3 and rotated, on frame 3 and about an axis 7 parallel to door 2 and perpendicular to the Figure 1 plane, to transmit the movement of lever 4 to a cable 8 activating lock 5; and a retaining body or pendulum 9 connected to frame 3 and rotated, by any inertial forces and about an axis 10 parallel to axis 7, from a normal position of noninterference with rocker arm 6, to a retaining position wherein pendulum 9 retains rocker arm 6 in a position corresponding to the rest position of lever 4.
  • lever 4 On the end opposite the hinged end, lever 4 comprises an appendix 11, which extends crosswise to axis 7 and through opening 2a towards frame 3 and is movable with lever 4 in a direction D crosswise to axis 7 and to door 2.
  • Appendix 11 is defined by a flat, substantially rectangular plate lying in a plane substantially parallel to the Figure 1 plane, and fitted, close to a free end opposite the end connected to lever 4, with a cylindrical pin 12, which is parallel to axis 7 and engages in rotary and transversely sliding manner an axial slot 13 formed along an arm 14 of rocker arm 6.
  • Rocker arm 6 comprises a further arm 15 substantially perpendicular to arm 14 and to axis 7, and fitted with a terminal 16 of cable 8, which is a known cable - in the example shown, a BOWDEN cable - and is connected to lock 5 through a cable guide 17 integral with frame 3.
  • Rocker arm 6 is connected to a helical torsion spring 18, which is coaxial with axis 7 and keeps rocker arm in a closed position (shown in Figure 1) wherein lever 4 is in the rest position closing lock 5, and lock 5 is in the closed position.
  • Frame 3 comprises a wall 19 perpendicular to the Figure 1 plane and extending crosswise to and inwards of door 2 alongside appendix 11; and a fork 20 in turn comprising two parallel, facing wings 21 and 22 extending in respective planes perpendicular to axes 7 and 10, and from the opposite surface of wall 19 to that facing appendix 11.
  • wings 21 and 22 have respective through holes 23 and 24, which are coaxial with axis 10 and define respective seats engaged in rotary manner by respective end portions 25 and 26 of a cylindrical pin 27 mounted for rotation about axis 10 and having a central portion 28 integral with one end of pendulum 9.
  • Pendulum 9 is interposed between wings 21 and 22, extends from pin 27 towards appendix 11, and, at the free end opposite the end connected to pin 27, comprises a body 29, which, by means of a helical torsion spring 30 coaxial with axis 10, is normally maintained in said noninterference position (shown by the continuous line in Figure 1) contacting a stop member 31 integral with frame 3.
  • pendulum 9 rotates by inertia (anticlockwise in Figure 1) about axis 10 and in opposition to spring 30 so that body 29 comes to rest against a shoulder 32 on wall 19 and in a retaining position (shown by the dash line in Figure 1) wherein body 29 interferes with the path of arm 14 to prevent rocker arm 6 - which, given its shape, is relatively unaffected by the inertial forces - from moving by force of inertia out of the closed position.
  • spring 30 comprises two ends 33 and 34 compressed against respective retaining ribs 35 and 36 integral with intermediate portions of wings 21 and 22 respectively; two helical portions 37 coaxial with axis 10 and wound about pin 27; and a substantially U-shaped central portion 38 forced against the surface of pendulum 9 facing lever 4.
  • pendulum 9 comprises two parallel, spaced appendixes 39 and 40, from which extend respective opposite pins 41 and 42 integral with respective appendixes 39 and 40 and coaxial with each other.
  • Pin 41 extends from appendix 39 towards wing 21, and engages hole 23 in rotary manner.
  • Pin 42 has a central portion connected integrally to appendix 40, and projects outwards of appendix 40 to engage hole 24 in rotary manner.
  • Pin 42 also comprises a portion 43, which is integral with appendix 40, projects towards and terminates a distance from appendix 39, and is wound with an intermediate helical portion 44 of a torsion spring 45, the opposite ends of which define two portions 46 and 47 compressed respectively against a retaining rib 48 carried by wing 22, and against the surface of pendulum 9 facing lever 4.
  • handle 1 Operation of handle 1 is easily deducible from the foregoing description with no further explanation required. It should be pointed out, however, that providing pendulum 9 with a rigid hinge pin ensures extremely accurate guidance of pendulum 9 about axis 10, and a relatively high degree of safety of handle 1 as regards accidental opening of door 2 in the event of lateral impact.
  • Using helical torsion springs ensures pendulum 9 is subjected to specific and, above all, constant forces, even in the event of accidental impact, and, on the other, provides for fast, easy assembly of the springs to the various rigid pins and for univocal positioning of the pendulum 9.
