Definitions

  • the present invention relates to locking arrangements and in particular to locking arrangements on vehicle doors.
  • Superlocking thus prevents opening of the door by an unauthorised person, such as a thief, by the breaking a door window, and reaching inside to open the door.
  • an unauthorised person such as a thief
  • the thief has access to the inside handle and inside lock button (sill button) and by forcing one of these, as appropriate, the thief can break a part of the locking arrangement such that the locking arrangement can be moved from the superlocked condition to the locked condition thereby allowing the thief to open the door using the inside door handle.
  • An object of the present invention is to provide a more secure form of locking arrangement.
  • a locking arrangement included a manually actuatable element connected via a transmission path to a latch assembly, the latch assembly having unlocked locked and superlocked conditions, the latch assembly being moveable between the unlocked locked and superlocked conditions by operation of an actuator, the latch assembly being moveable between the unlocked and locked conditions by operation of the manually actuatable element, the transmission path including resilient means to limit the force applied by the manually actuatable element when the manually actuatable element is operated to attempt to move the latch assembly from its superlocked condition
  • FIG. 1 With reference to figures 1 to 4 there is shown schematically a locking arrangement 10 having a manually actuatable element in the form of a sill button 12 connected by a transmission path 14 to a lock lever in the form of a lock gear 16.
  • the sill button includes a manually engagable portion 18 for being gripped between a thumb and forefinger of a driver or the like.
  • Manually engagable portion 18 is mounted on a stem 20 slidably mounted in a sill 22 of an associated door.
  • a transmission path stop At the lower end of the stem is a transmission path stop in the form an abutment 24.
  • the beneath abutment 24 is a pin 25.
  • Sill button 12 has an unlocked, locked and superlocked position as shown in figures 1 to 3 respectively.
  • the latch assembly 13 includes lock gear 16, gear pinion 36 and associated motor 42 (positioned behind the lock gear 16 and shown in figure 2 for clarity), solenoid pin 34 and associated solenoid (not shown), and further elements, such as a rotating claw, and pawl, that enable the latch assembly to secure an associated door in a closed position.
  • tension spring 38 is included in the latch assembly, though in further embodiments this need not be the case.
  • Lock gear 16 is rotable about axis A and is connected to further elements (not shown) of the latch assembly which are capable of providing an unlocked, locked, and superlocked condition of the locking arrangement.
  • the lock gear 16 includes an array of gear teeth 26 on a part of its periphery.
  • the lock gear further includes a recess 28 having stop surfaces 30 and 32.
  • a solenoid (not shown) includes a solenoid pin 34 which is movable into the recess 28 (see figures 1 and 2) and can be withdrawn (see figures 3 and 4) allowing stop surface 30 of lock gear 16 to pass over the pin.
  • a gear pin 36 is driven by a motor (not shown).
  • Lock gear 16 further includes a pin 33.
  • tension spring 38 Mounted between pins 33 and 26 is a tension spring 38.
  • the tension spring is such as to be coil bound state when in a free condition.
  • Such a spring is capable of acting in a non resilient manner under compressive loads and under tensile loads up to a predetermined load. Above the predetermined load the tension spring acts in a resilient manner as will be further described below.
  • the locking arrangement can be power locked by operation of the motor causing pinion 36 and hence lock gear 16 to rotate anticlockwise such that stop 30 abuts against the projecting solenoid pin 34.
  • the locking arrangement can be locked by an operative depressing the sill button wherein the tension springs 38 acts under compression in a non resilient manner until such time as stop surface 30 abuts projecting solenoid pin 34.
  • the vehicle arrangement can be unlocked either by power operation of the motor or by manual lifting of the sill button.
  • the components needs only be designed to withstand a predetermined force and this has benefits both in terms of security and in terms of minimising cost and weight of the assembly.
  • the transmission path connecting the manually engageable portion 18 within the lock gear 16 includes stem 20, pin 25, tension spring 38 and pin 33.
  • the transmission path 14 further includes a transmission path stop provided by abutment 24 when in contact with the under surface 23 of sill 22.
  • FIG. 1 With reference to figures 5 to 9 there is shown a second embodiment of a locking arrangement 110 wherein components performing substantially the same function as those in locking arrangement 10 are labelled 100 greater.
  • tension spring 138, and release lever 152 are included in the latch assembly, though in further embodiments this need not be the case.
  • tension spring 138 is connected to a pin 150 mounted on an arm 154 of the release lever 152.
  • a further arm 156 of the release lever 152 is connected via push/pull cable inner 158A of push/pull cable 158 to an inside release door handle 160.
  • Push/pull cable 158 further includes a cable sheath 158B within which cable inner 158A can reciprocate.
  • cable inner 158A is sufficiently rigid to be able to act in compression without buckling in this particular installation.
  • the release lever is pivotally mounted about axis B and is connected to further mechanisms of the latch assembly and acts to move the pawl (not shown) to the released position and hence allow the latch claw (not shown) to open.
  • the release lever 152 is not connected to the pawl and hence movement of this release lever does not unlatch the latch.
  • the release handle 160, push/pull cable 158 and release lever 152 have a release position as shown as shown in figure 5, a unlocked position as shown in figure 6 and locked position as shown in figure 7.
  • the locking arrangement can also be moved from the unlocked position as shown in figure 6 to a locked position as shown in figure 7 by manually moving the release handle 160 to its locked position wherein push/pull cable inner 158A acts in compression to rotate release lever 152 anticlockwise about axis B further causing spring 138 to act in compression rotating lock gear 116 anticlockwise.
  • Locking arrangement can be moved from the locked position as shown in figure 7 to the unlocked position as shown in figure 6 by manually moving the release handle 160 to its unlocked position causing the push/pull cable inner 158A to act in tension and rotate release lever 152 clockwise which results in spring 138 also acting in tension and causing lock gear 116 to rotate clockwise.
  • spring 138 has been manufactured in a pretensioned condition to be coil bound. The tensile load applied to spring 138 by the moving of inside door release hand to its unlocked position is less than the in built pretension in the spring, thus the spring acts, in tension as a solid link of length M1 as the locking arrangement is moved to the unlocked position.
  • Alternatively powered operation of the motor can drive the lock gear 116 to the position shown in figure 6 from the position shown in figure 7.
  • any forcing of the release handle 160 will simply move the release lever 152 to the position as shown in figure 9 further extending the tension spring 158 to length M4. It will be noted that a transmission path stop in the form of an abutment 62 (only shown on figure 9) prevents the release lever 152 from rotating in a clockwise direction any further than as shown in figure 9.
  • pin 25, pin 33 and axis A are substantially in line with the sill button in its lowered and raised position. Thus there is substantially no turning moment applied to lock gear 16.
  • pin 150, pin 133 and axis B of lock gear 116 are also substantially in line with the release handle 160 in its unlocked and released positions.
  • release handle 160 and lock gear 116 includes bowden cable 158, release lever 152, and tension spring 138.
