Abstract
A vehicle door securing mechanism including;-
Description
This invention relates to securing mechanisms for latching and selective
locking of doors and other closures of vehicles with particular application to
the rear passenger doors of cars and light vehicles likely to be accessible to
children in the vehicle but remote from immediate adult supervision.
The invention has particular application to mechanisms forming part of
locking systems of the kind in which the individual locks, and possibly the
latching and unlatching of the related doors, are power operable and
interconnected through a central control unit operable from within or outside
the vehicle, herein referred to as "central locking systems".
The object of the invention is to provide mechanism incorporating a
child safety facility which is convenient and reliable in operation, of simple
and durable construction, and in which the child safety condition can be set
and cancelled by remote control.
According to the invention there is provided vehicle door securing
mechanism including:-
Preferably the release lever also interacts with the locking means
whereby movement of that lever in the direction for unlatching the door shifts
the locking means, if in a locked condition, to unlocked condition.
An example of the invention is now more particularly described with
reference to the accompanying drawings wherein;
The securing mechanism, incorporating latching mechanism and locking
mechanism of the related door is located by and in a box-like housing 10
shown schematically in the drawings to form a unitary assembly for mounting
in the door.
The latching mechanism includes a conventional rotating claw bolt and
co-acting pawl operating to releasably retain the door in closed condition, is
pawl being released when the door is to be opened as by operation of the
interior or exterior door handles by a latch release member 12 shown in part
in figure 2. For some applications the latch mechanism may incorporate power
operated latching engagement closing the door, for example as described in our
co-pending application GB9710602.5 dated 23rd May 1997 and/or power
unlatching when the door is to be opened as described in our co-pending
application GB9713407.6 dated 26th June 1997. Such power operations will
be controlled from a central locking system on the vehicle.
The mechanism further incorporates locking mechanism as referred to
above, again of known construction not shown in the drawings apart from a
rocking lock/unlock lever 14 in FIG.2 and again the locking mechanism may
incorporate power actuation as part of a central locking system in known
manner.
Release means of the mechanism includes a release lever 16
fulcrummed on a fixed pivot 18 and having a first downwardly dependant arm
20 operatively linked to an inside handle (not shown) of the related door by
a pull rod 21, and a second arm 22 extending generally leftwardly as viewed
in the drawings to abut left hand arm of lock/unlock lever 14.
An unlatching lever 24 of bell crank form is also fulcrummed on pivot
18 but can pivot independently of lever 16. A downwardly dependant arm 26
of lever 24 overlies arm 20 of lever 16 while the other arm 28 of lever 24
projects rightwardly and is provided with a terminal projection abutting
downwardly against a similar projection of latch release member 12.
The underlying part of arm 20 of lever 16 also defines a drive
formation in the form of a bayonet slot 34 best seen in detail view FIG.2A,
having a closed upper end but opening from arm 20 downwardly and to the
right. Drive dog 32 extends into slot 34.
A child safety power actuator 36, in this example a rotary electric
motor having a worm and nut drive output for providing rectilinear motion
although it is to be understood that various other forms of power actuator
could be used, is mounted within housing 10. The nut 38 moves vertically and
is engaged with the left hand arm of a rocking lever 40 pivoted at 42. The
distal end of the right hand arm of lever 40 is coupled to drive dog 32 by a
generally vertical link 44 so that operation of actuator 36 moves dog 32 from
one end to the other of slot 30.
The drawings show the mechanisms in child safety condition, that is
actuator 36 has displaced rocking lever 40 clockwise carrying dog 32 to the
lowermost end of slot 30. In this position the two levers 16 and 24 are
uncoupled for independent movement because dog 32 is at the open end of
bayonet slot 34. Thus, operation of the inside handle of the door will merely
cause idling movement of release lever 16 while unlatching lever 24 will
remain stationary leaving the door securely latched.
The child safety condition is cancelled, making the inside door handle
operative, by remote control applying power to actuator 36 to draw dog 32
upwards so that it engages the closed upper end of bayonet slot 34 coupling
lever 16 and 24 so that operation of the door handle causes arm 24 to depress
latch release member 12 effecting manual unlatching.
In some applications, for improved security, manual operation of the
locking mechanism from the inside of the related door is effected by a cill
button which is depressed flush with the door trim in locked condition. This
is to preclude attempts to unlock the door from the exterior by "fishing"
through a window aperture with some kind of tool to engage the cill button.
As the button cannot be raised directly to unlock the door, eg in an emergency,
the inter-engagement of second arm 22 of release lever 16 with lock/unlock
lever 14 is provided, thus whenever the inside door handle is operated, whether
or not the child safety has been set, the resulting displacement of release lever
16 will return the lock mechanism to unlocked condition so that the door can
be opened, at least from the outside, in an emergency and/or if power actuation
should fail, eg due to a flat battery.
It will be understood that variations and adaptations of the above described
mechanism may be made as will be apparent to those skilled in the art to suit
various operating requirements and constructional needs. The drive dog may
take various forms and may be shifted to set or cancel child safety by various
types of power actuator, for example a solenoid type actuator could provide
direct push/pull shifting of the drive dog or geared angular drive could be
provided as by shifting dog 32 along a curved slot. It will also be seen that
the closed-ended slot 30 could be provided in the arm 20 of lever 16 with the
dog co-acting with an open-ended slot or equivalent formation in arm 26 of
lever 24.
