The present disclosure relates to an ignition switch cum steering lock (100) (herein referred as ("ignition switch") having an integrated locking mechanism to provide a means for actuating at least one peripheral via two different actuation cables in an ignition switch cum steering lock.
Figures 1 illustrates the perspective view of the ignition switch (100) showing the assembly of the two components i.e. a cover module (2) which covers the ignition switch (100) from the top. Figure 2 and 3 illustrates the exploded view of the ignition switch illustrating all the components of the ignition switch (100) comprising a lock module (1), a cover module (2), a knob (3), a gear (4), a pivot pin (5), an actuator plates (6A and 6B), a cover plate (7), a locking plate (8), a side cover (9), a driven gear (10), a compression spring (11), a torsion spring (12), a rotor (13), and a lock body (14). The cover module (2) covers the ignition switch and comprises a cavity which corresponds to a keyhole to secure the key inside the switch assembly. The rotor is secured inside the lock body and thereby forming the lock module (1).
The ignition switch (100) comprises a lock module (1) having a lock body (14) and a rotor (13). The lock body (14) acts as a housing of the ignition switch wherein all the components are secured in the lock body (14). The lock body (14) comprises a first pivot leg (14a) which is positioned at the top of the lock body, a second pivot leg (14b) which is placed below the first pivot leg (14a). The lock body also comprises a first cavity (14c) positioned in between the first and second pivot leg and a second cavity (14d) located near the bottom of the lock body (14). A hollow surface (14e) is also present in the lock body which secures the rotor (13) in such a manner that top portion of the rotor (13) projects outside from the hollow surface (14e).
The rotor (13) is secured in the lock body and rotates inside the lock body by the insertion of the ignition key and moves in the direction in which the ignition key is

rotated. The rotor is cylindrical in shape having a protrusion rib (13a) along its periphery at the top of the rotor, a slot (13b) adjacent to the protrusion rib and a depressed surface (13c).
As illustrated in figures 3 and 5 the knob (3) of the ignition switch (100) is having a grip surface which is manually operated by the user and pivotally connected with the gear. The knob (3) is having an opening (3a) near the bottom side through which the pivot pin (5) passes through and pivotally connect the knob (3) and gear (4) with the lock body (14) and side cover (9).
Figure 4 A and 4B illustrates the gear (4) of the ignition switch assembly (100) having gear teeth (4A) uniformly formed on the gear surface. The gear is having gear leg (4c) which is protruded outwards from the gear surface. The knob (3) is attached to the gear (4) through the connection made between the gear leg (4C) and cavity (3 A) on knob (3). The gear also comprises a cavity (4B) which act as a housing for the locking plate (8). The gear (4) is pivotally mounted between knob (3) and a pivot leg (14A) of lock body (14) as illustrated in figure 12.
Figure 6 illustrates the driven gear (pinion) (10) having driven teeth (10A) which is equally distributed on the top surface of the driven gear (10). As seen in figure 14, the gear teeth (4A) of gear (4) is engaged with the driven teeth (10 A) of driven gear (10). The driven gear (10) is allowed to pivotally rotate about the second pivot leg (14B) between the lock body (14) and the side cover (9). The rotary movement of the knob (3) and the driven gear (10) is limited by the stopper (10C) projected from the driven gear (10) and cavity (14D) on lock body (14).
As illustrated in figure 12-14 ,two actuator plates (6 A and 6B) rest on the bottom surface (10B) of driven gear (10) and are allowed to pivotally rotate about the second pivot leg (14B) between the lock body (14) and the side cover (9). The actuator plate (6a,6b) is having a proximate end (6al;6bl) which rests on bottom surface (10b) of the pinion (10) and a distal end (6a2;6b2) which is connected with an actuation cables.
Figure 8 A and 8B shows the perspective view of the actuator plates wherein on end of the actuator plate rests on the bottom surface and other end is attached with an actuation cable. On rotating the knob (3) and gear (4) in anticlockwise direction, the driven gear

(10) is rotated in clockwise direction and hence the actuator plate (6A) is lifted. Actuation cable (not shown) attached to the actuation plate (6A) is actuated thereby performing the designated function. On rotating the knob (3) and gear (4) in clockwise direction, the driven gear is rotated in anticlockwise direction and this time actuator plate (6B) is lifted. The torsion spring (12) brings back the whole mechanism consisting of actuator plates (6A and 6B), driven gear (10), gear (4) and knob (3) to neutral position.
Figure 7 illustrates the perspective view of the locking plate (8) having an elongated bar (8B) at one end which is adapted to received in the gear cavity(4B). The resiliency energized locking plate (8) having a front end (8a) and a bottom end (8b). The front end (8a) is operationally configured to engage with the protrusion rib (13a). The other end of the locking plate is secured inside the opening (14c) of the lock body. Figure 9 illustrates the front view of the side cover (9) which enables the connection of knob (3), gear (4) and driver gear (10) with the lock body (14). The side cover (9) is connected with the lock body (14) with the help of fasteners. Figure 10 illustrates the rotor of the switch assembly having a protrusion rib (13a) along its periphery.
The following paragraph describes the working of the ignition switch assembly.
Figure 15 illustrates the sectional view of the ignition switch assembly when the switch is at locked position. The locked position of the switch is the position at which the user is not able to rotate the knob and the operation of the knob is restricted. To restrict the operation of knob (3) to a particular position with respect to rotor (13), a locking plate (8) is housed inside the cavity (14C) of lock body (14) between the rotor (13) and the gear (4). A cover plate (7) retains the locking plate (8) with the assembly. The protrusion rib (13 A) of the is in constant engagement with the front end (8A) of locking plate (8). The design of this protrusion rib (13A) is such that it pushes the locking plate (8) thereby engaging the bottom end (8B) of locking plate (8) with the hole (4B) of gear (4). Locking plate (8) therefore restricts the movement of gear (4).
At a particular pre-determined position of rotor (13) i.e. when the user moves the rotor with the help of ignition key, the rotor moves in the such a way that there disengagement of protrusion rib (13 A) with the locking plate and the rotor is moved to the position of 13B. At this position, the locking plate (8) comes in front of the slot (13B) of the rotor

(13) and the compression spring (11) disengages the bottom end (8B) of locking plate (8) from the hole (4B) of gear (4), thereby allowing the gear (4) to operate freely.
The rotor (13) also undergoes downward push vertical movement along its axis. This push movement might damage the locking plate (8) if the rotor (13) is at switch unlock position (as in fig 2). Therefore, to restrict the push action of rotor (13) at switch unlock position (as in fig 2), a protrusion (14A) is made in lock body (14). The cavity (13C) made on the protrusion rib (13A) of rotor (13) allows the push movement of rotor (13) only in the required position, while the protrusion rib (13A) of rotor (13) restricts the push action in any other position.
The primary advantage of the locking device is integrated with actuation system for operating at least one peripheral accessories. Another advantage of the locking device is that it is a cost-effective solution for manufacturing the components. Another advantage of the locking device is that the switch assembly disclosed has minimum number of parts, and reduces assembly time. Another advantage of the present locking device is that it provides improved reliability and rigid working components.
