SHUTTER MODULE FOR CYLINDER LOCK
FIELD OF INVENTION
The present invention relates to a shutter module for cylinder lock. More specifically, the said
invention relates to mechanism and operation of shutter in a cylinder lock in vehicles which
is related to auto closing and opening by a remote key along with an option of manual closing
and opening of the shutter by user.
BACKGROUND AND PRIOR ART OF INVENTION
Generally most of the vehicles are provided with cylinder lock. Such locks are being opened
by insertion of key in the provided key hole (i.e. ignition lock). For example ignition lock of a
vehicle is provided with a shutter to prevent from unauthorized access to lock. In case of two
or three wheelers vehicles and open roof four-wheeler vehicles, when key is removed from
the lock, the lock is open to environment which may cause many problems such as
miscreants/thieves may insert any sharp metallic object to unlock the cylinder lock. Further as
the lock is completely open to environment, therefore, dirt, water or other foreign particles
etc. may damage the lock or may jam the said lock. Eventually, such conditions cause the
reduction in the life of lock.
However, to overcome these shortcomings, various solutions have been provided such as to
cover the cylinder lock with the help of a shutter. There are solutions which provide shutter to
protect the cylinder lock with a mechanism, however, having many parts in such mechanism
results a complex assembling of such part.
In respect of operation of shutter, it has been found that a shutter is provided to cover the key
hole at closed position and open the keyhole at opened position by user with a magnet key.
The use of magnet key for closing and opening of cylinder lock key hole does provide an
inconvenience due to manual operation.
Also, there are few solutions whereby one operation of shutter (i.e. either opening or closing)
of cylinder lock protection device is governed by a switch which needs to press by the user
and second operation require manual interface.

Figure 4a-4c illustrates the opening of the shutter plate (2) using the remote key (11) (not
shown in figure 4a-4c) according to an embodiment of the present invention. As shown in
figure 4a, at close position, the leg (2b) formed on the end (2d) of the shutter plate (2) abuts
with the axial face (6c) of the projection (6b), thereby restricting the rotation of the shutter
plate (2) due to restoration force of the resilient means (10a). The resilient means (10c)
provided for the resilient movement locking mean (6), remains in de-energized condition at
close position of the shutter plate (2). The resilient means (10a) of the shutter plate (2)
remains in energized condition at close position of the shutter plate (2). At close condition of
the actuation switch (7) remains in pushed condition by the shutter plate (2). As the shutter
plate (2) releases the actuation switch (7) moves to unpushed condition, and ECU gets the
signal to cut off power and deactivate the actuator. At open condition of the shutter plate (2),
the actuation switch (7) will be in un-pushed condition. As the shutter plate closes the key
hole, the actuation switch (7) is pushed by the shutter plate (2) and ECU gets the signal to cut
off power and deactivate the actuator. In this way actuator activation is controlled by the
actuation switch (7).
Upon, the activation of the actuator (8) by the user using the remote key/transmitter (11), the
actuator driven rotor (5) is rotated in anti-clockwise direction. As the actuator driven rotor (5)
is rotated in anti-clockwise direction, the projected leg (5b) of the actuator driven rotor (5)
pushes/slides the locking mean (6) to energize the resilient mean (10c) through/via slant face
(6d) of the projection (6b) provided on the locking mean (6). Hence, locking of shutter plate
(2) is released which results in rotation of the shutter plate (2) to open position due to
restoring force of resilient mean (10a). At open position the actuation switch (7) returns to
un-actuated/un-pushed condition, thereby actuation switch (7) send signals to ECU to cut-off
and deactivate the actuator mean (8).
Figure 5a-5b illustrates the closing of the shutter plate (2) using the remote key (11)
according to an embodiment of the present invention. At open position of the shutter plate
(2), the key hole can be accessible to operate the cylinder lock.
11
Upon, the activation of the actuator (8) by the user using the remote key, the actuator driven
rotor (5) is rotated in clockwise direction. As the actuator driven rotor (5) is rotated in
clockwise direction, the extruding arm (5b) of the actuator driven rotor (5) pushes the end
(2b) of the shutter plate (2) which further pushes the slant face (6c) of the projection (6b)
through the projected leg (5b) and rotates the shutter plate (2) about the pivot (2c). During
rotation of shutter plate (2) from open position to close position, the resilient mean (10a) of
the shutter plate (2) moves to energized/stretched condition. The base (1) of cylinder lock
comprising an actuator (8) which is engaged with the driven actuator means (5). At open
position the actuator (8) rotates the driven actuator mean (5) in a pre-determined direction
and pushes the shutter end (2d) by the extruded portion (5a) of actuator driven rotor (5). As a
result the shutter plate (2) rotates to energize the resilient mean (10a) with respect to the pivot
at (2c) and the shutter plate (2) is locked by the locking mean projection (6b) at close
position. Driven actuators mean (5) consist of a projected leg (5b) beneath the extruded
portion (5a) During the rotation of the shutter plate (2) about pivot (6c) form open to close
position, the leg (2b) pushes/ slides the locking mean (6) to energize the resilient mean (10c)
through the slant face (6d) of the projection (6b) of the locking mean (6). As the shutter plate
(2) reaches the closed position, the leg (2b) releases the slant surface (6d) thereby locking
mean (6) moves back due to the restoring force in resilient mean (10c). As the shutter plate
(2) reaches the closed position, the leg (2b) move past the slant surface (6d) which results in
restoration of the resilient mean (10c). Hence the shutter plate (2) is locked at close position
as the axial face (6c) fall in front of the leg (2b), thereby restricting the rotation of the shutter
plate (2) to open position due to restoring force of resilient mean (10a)..The cylinder lock
also comprises at least one actuator mean (8) that get activated by receiving signal from the
ECU. An actuation switch (7) being operationally configured with ECU to indicate the
position of shutter, so that the position of the shutter plate (open position or close position) is
known to the ECU.
As the shutter plate (2) reaches at close position , actuation switch (7) is pushed by the shutter
plate (2) and sends signal to the ECU to cut-off power and deactivate the actuator mean(8).
As the shutter plate (2) reaches at close position , the actuation switch (7) is pushed by the
shutter plate (2) and sends signal to the ECU to cut-off power and deactivate the actuator
mean(8).

Figure 6 illustrates a remote key (11) according to an embodiment of the present invention.
The remote key (11) has a magnetic unit (11a), an electronic unit (11b) and a mechanical unit
(11c). The magnetic unit (11a) of the remote key has plurality of magnets. The magnetic unit
(11a) is removably receivable in the cavity (1b) of the magnetic lock rotor (4). The Plurality
of magnet provided in the magnetic unit (11a) in such a manner that, the axis of magnets
provided in the base remain in axial alignment with the magnets provided in the magnetic
unit when the magnetic key is received in the cavity. The electronic unit (11b) comprises a
transmitter, to open and close the shutter plate (2).
Figure 7-8b illustrates manual closing and opening of the shutter plate according to an
embodiment of the present invention.
As shown in figure 7, the holes (1c) accommodate magnets along with the resilient
means(10d) which energizes to push the magnet upward and engaged with the projected
holes (4b) formed in the magnet lock rotor (4), thereby locking the magnetic lock rotor (4)
with base (1).The magnetic unit (11a) of the remote key (11), upon receiving in the cavity
(4a) unlocks the magnetic lock rotor (4) from the base (1) by means of polar repulsion
between the magnet of magnetic unit and the magnets disposed in the base (1), thereby
allowing the rotation of the magnetic lock rotor (4) against the restoring force of the resilient
mean (10b).
As shown in figure 8a and 8b, at close position, the locking mean (6) can be moved against
the restoring force of resilient mean (10c) through the projected leg (4c) which pushes the
extruded projection (6a) by rotating the magnet lock rotor (4) in a predetermined direction.
The Magnet lock rotor (4) is rotated by fitting/inserting the magnet unit of the remote key in
the cavity (4a). The magnet lock rotor (4) is provided with a resilient mean (10b) in such as
manner, that the magnetic lock rotor retain its position when the magnetic unit is removed
from the cavity (4a) due to the restoring force of resilient mean (10b). Upon rotating the
magnetic unit of the remote key in the cavity (4a) in predetermined direction unlocks the
rotation of the shutter and restores the shutter plate to open position. As the magnet lock rotor
(4) is rotated by fitting the magnet unit (11a) within the cavity (4a), the projected leg (4c)
pushes the locking mean (6) to energize the resilient mean (10c) through the extruded
projection (6a). The locking mean releases the leg (2b) of the shutter when the projected leg
13
(4c) pushes the projection (6a), thereby unlocking the rotation of the shutter plate about pivot
(6a) to open condition.
At open position the shutter plate (2) can also be rotated from open to close position by
manually applying force on projected pin (2a) to energize the resilient mean (10a), thereby
locking the shutter plate (2) through the leg (2b) with the axial face (6c) of the projection
(6b).
