Definitions

  • the present invention relates to a locking device for securing vehicles from theft.
  • the invention relates to a locking device for immobilizing the foot pedal of a vehicle, such as the clutch and/or brake pedals.
  • Pedal locks are a popular means for securing vehicles from theft. This is seemingly owing to their being perceived as more secure than other forms of vehicle component locks, such as those that secure the steering wheel or gear stick. Vehicle pedal locks available in the market may be categorized into one of two types, namely removable locks and installed locks.
  • Installed pedal locks involve the device being securely installed in the vehicle by bolting or anchoring it to an immovable part of the vehicle such as the floor board or steering column.
  • floor- or steering column-anchored pedal locks include CN200988477, WO2004108488 and US6,662,894.
  • the locking or immobilizing principle of known installed pedal locks involves a movable member which bars, clamps or blocks the pedal or pedal arm from operation. This is generally achieved by the user or driver actuating a lever or handle at an upper end of the pedal lock closest to the driver to retract the movable member into a locked position, which physically blocks the pedal or pedal arm from operation.
  • the movable blocking member sometimes can also be pushed or jerked into locking position by a sudden impact or collision force. Such events may accidentally lock up the foot pedal, rendering it non-operational, which can be dangerous if the brake pedal is accidentally locked whereby the driver is not able to effectively stop the vehicle after such an initial impact or collision. Additionally, such pedal locks may be bulky, making their installation difficult in the confined space of the foot well of the vehicle.
  • Existing antitheft locks generally include a lock cylinder with a plurality of locking bodies disposed within a hollow housing or casing, such that rotational movement of the lock cylinder within the lock housing is inhibited or prevented by the action of these locking bodies. It is only by inserting a specific corresponding key into the key hole of the lock cylinder and driving conversion of the lock catch assemblies to an unlocked position by virtue of the specific shape of the key, that the lock can be unlocked by rotating the lock cylinder by way of the key. To this end, the locking bodies engage the outer lock housing to be in a locked state, but when the corresponding key is inserted into the key hole of the lock cylinder locking bodies are separated from the outer lock housing so as to result in the lock being unlock.
  • a locking device for securing a foot pedal of a vehicle in an inoperable position comprising:
  • a frame having a first end and a second end and defining a longitudinal axis

  • a first locking mechanism mounted at the first end of the frame and adapted to lock the extendable locking arm in the locked position; and a mounting member extending from the frame and adapted to be secured to a portion of said vehicle.
  • the locking arm suitably comprises a first arm portion and a second arm portion pivotable relative to each other so as to facilitate movement of said extendable locking arm from the unlocked position to the locked position.
  • the first arm portion and the second arm portion when in the unlocked position are substantially perpendicular to each other.
  • the first arm portion and the second arm portion are substantially colinear.
  • the extendable locking arm comprises a biasing member configured to bias the locking arm toward the unlocked position.
  • the biasing member is or comprises a helical torsion spring.
  • the biasing member engages a portion of both the first and second arm portions so as to facilitate biasing of said extendable locking arm to the unlocked position.
  • the locking device of the present aspect suitably further comprises an actuator operably coupled to the extendable locking arm, so as to facilitate extension of the extendable locking arm to the locked position upon actuation thereof.
  • the actuator comprises a lever operably coupled to a slide mechanism, wherein actuation of the lever facilitates linear movement of the slide mechanism.
  • the locking device further comprises a second locking mechanism mounted at the first end of the frame adjacent the first locking mechanism, wherein the second locking mechanism is adapted to lock the first locking mechanism after the first locking mechanism has been locked.
  • the extendable locking arm is rotatable about the longitudinal axis of the frame.
  • the extendable locking arm is secured to a rotatable member rotatably disposed within the second end of the frame.
  • the rotatable member is or comprises an axial tube.
  • the locking device of the present aspect suitably further comprises a guide member extending from a second end of the frame and adapted to facilitate extension of the extendable locking arm.

  • This sliding movement is then translated into rotational movement of the axial tube 102 within the frame 110 by way of an inclined portion 184 substantially acting as a cam surface and contacting a raised portion 186 of a ring member 185.
  • the ring member 185 is rotatably mounted within the first end 1 11 of the frame 110 and of suitable dimensions to be substantially co-linear and flush therewith.
  • the ring member 185 is further secured to a proximal end of the axial tube 102, thereby allowing for translation of any rotational movement of the ring member 185 produced by the slide mechanism 180 to the axial tube 102.
  • a compression spring 183 is further provided within the slide mechanism 180 and operably coupled to the slide member 182 to facilitate return of the slide member 182 to its original position after use.

  • actuation of the slide mechanism 180 to produce rotational movement of the axial tube 102 and extension of the locking arms 130, 135 can be produced by alternative mechanical means, such as a button or a lever mechanism, operably coupled to the slide mechanism 180.

  • the handle may further be coupled to a compression spring to facilitate its return to its original position following rotational movement thereof.
  • Figure 6 illustrates the pulling up of the lever 191 which actuates forward or linear movement of the sliding mechanism 180. As described previously, this linear movement is translated, via the inclined portion 184 which provides cam action against the raised portion 186, to rotational movement of the axial tube 102 and thus extends the locking arms 130, 135 into an extended locked position. In order for the locking arms 130, 135 to be retained or locked in this extended position during use, the locking device 100 further includes first and second locking mechanisms 160, 170.
