ABSTRACT:

FIELD OF THE INVENTION
This invention relates to a device to assist in gaining access to a locked vehicle.
BACKGROUND TO THE INVENTION
Many vehicles are unintentionally locked with the keys inside the vehicle or keys are lost with the vehicle locked. Motor vehicle door locks are becoming more and more sophisticated to prevent theft. This sophistication however makes it difficult for legitimate access to be obtained when necessary under circumstances as set out above or at accident scenes.
OBJECT OF THE INVENTION
It is the object of this invention to provide a means which will facilitate the opening of a locked vehicle door for which a key is not available.
SUMMARY OF THE INVENTION
In accordance with this invention there is provided a vehicle access device comprising a pair of sheathed elongated filaments having independant controls at one end, a first filament having an end opposite the controls with a clamping device secured thereto and the end extensible and retractable relative to the end of its sheath and the second filament retractable in its sheath to provide a bend in the sheath for the first filament at a predetermined distance from the end remote from the controls.
Further features of this invention provide for the filaments to share a common sheath, for the first filament to have a contractable clamping device at the end thereof remote from the controls and for the contractable device to be interchangeable with different kinds of clamping devices.
The invention also provides for the first filament to be a cable and for the control to be by means of a knob on the end of the cable enabling the cable to be retracted through a hollow boss provided on the end of the sheath and for a clamp to be provided operable between the cable and the boss. The invention also provides for there to be a rigid connecting piece between the filament and the knob extending through the boss.
Still further features of this invention provide for the second filament to be made of synthetic resin material such as nylon and for the control to be a rotatable anchor within the boss and for the filament to be anchored in a first collar within the sheath adjacent the end remote from the controls, to pass through a second collar spaced from the first collar towards the controls with the second cable extending outside the wall of the sheath between the collars.
The term “Bowden-type cable” is used in this specification to describe the type of control which has a sheath around a filament the sheath being anchorable at each end so that the filament within the sheath can be moved relative to at least one end of the sheath to enable the other end of the filament to exercise a desired movement of a component secured to that end.
