FIELD OF THE INVENTION
The present invention relates to a wheel lock for locking wheels of vehicle(s).
More specifically, the said invention relates to the construction, assembly and
functional mechanism of a wheel lock for locking wheels of vehicle(s), whereby
the said wheel lock provides safety against theft by jamming the wheel.
BACKGROUND OF THE INVENTION
Generally locking skewers are used in motorbikes and bicycles to provide
protection against theft by immobilizing the vehicle. For example an ‘O-type’ lock
is commonly seen in bicycles. Such locks are mounted on the rear mud-guard of
the bicycle and have a circular shaped locking rod that passes through the wheel to
jam it. Upon insertion of the correct key, the lock can be unlocked.
Similarly, a ‘U-type’ lock is used for ceasing the movement of the front wheel of
motorbikes. The lock is mounted on the front suspension shockers of the
motorbike and a locking rod passes through the front wheel to cease it when in
locked position. This lock requires manual unlocking by insertion of the correct
key by the rider/user in the key hole of the lock.
However, there have been incidents of miscreants dismantling/ dismounting the
lock assembly from the wheel of the vehicle when lock is at unlocked condition.
Also, the ‘U-type’ lock used in motorbikes has a completely detachable U-rod.
This means that taxing human effort is required to unlock the wheel of the vehicle
by, firstly, pulling out the rod and then fitting this rod in an isolated holding
groove, which in most applications, is located on the other side of the wheel.
To overcome these shortcomings, the inventors have felt a need of developing a
wheel lock for locking wheels of vehicle(s) with an improved mechanism that
3
would be more agile in use, would provide safety against ‘theft by
dismantling/dismounting of the lock assembly’ and be simpler in usage by the end
user.
OBJECTIVES OF THE INVENTION
The primary objective of the present invention is to provide a wheel lock for
locking wheel of vehicle(s), whereby the safety of an automobile would be
enhanced by preventing wheel rotation by means of an external lock mounted on
the wheel hub/suspension rods/any feasible mounting location in the vicinity of the
wheel and facilitating the user to manually lock/unlock the wheel movement.
Another objective of the present invention is to provide a wheel lock which cannot
be dismounted from the vehicle without the correct key.
SUMMARY OF THE PRESENT INVENTION
The present invention provides a wheel lock for locking of wheels of vehicle(s),
comprising a lock box comprising two longitudinal sides and two transverse sides.

11
Figure 3 depicts a sectional view of the locking rod. Referring to figure 3, the
locking rod is a solid cylindrical structure. However, the shape and dimensions
may vary according to other embodiments of the present invention. The locking
rod comprises a proximal end (2c) and a distal end (2d). Located at the proximal
end (2c) of the locking rod is a flat portion (2e). The geometrical shape of the flat
portion (2e) may be circular, square, rectangular, oval etc. according to various
embodiments of the present invention. A first groove (2a) is located near the
proximal end of the locking rod at a predetermined distance from the flat portion
(2e). The said first groove (2a) is trapezoidal circular in shape such that the sloping
face (s) is directed towards the distal end (2d) of the locking rod. A second groove
(2b) is located near the distal end (2d) of the locking rod (2) at a predetermined
distance from the flat portion (2e). The said second groove (2b) is trapezoidal in
shape such that the sloping face (s) is directed towards the proximal end (2c) of the
locking rod. It is to be noted that the depth (d1) of first groove (2a) is more than the
depth (d2) of the second groove (2b). The said first and second grooves (2a, 2b) are
adapted to mate with the first end (8a) of the first locking lever (8) during
locking/unlocking of the said wheel lock.
As shown in figures 4(a)-(c), the integral rotating element (10) comprises a through
transverse slot (10a) adapted to accommodate a locking rod (2) in the transverse
direction. A longitudinal slot (10b) is also formed in the said integral rotating
element (10). The longitudinal slot (10b) is formed perpendicular to the transverse
slot (10a); and extends from the transverse slot (10a) to the first aperture (12) in the
interior of the lock box (1). The longitudinal slot (10b) is adapted to guide the
movement of the first locking lever (8) in the longitudinal direction in the integral
rotating element (10). A stopper (10c) is located on the outer periphery of the
integral rotating element (10). The stopper (10c) is adapted to control the rotational
movement of the integral rotating element between its extreme positions. Mating
slots (10d, 10e) are formed at right angles on the integral rotating element (10).
The mating slots (10d, 10e) being provided on the side of the integral rotating
element in contact with the lock box (1). The said mating slots (10d, 10e) are
12
adapted to mate with the shoulder face (8c) on the second end (8b) of the first
locking lever (8) (refer fig. 5) during locking/unlocking of the said wheel lock.
Figure 5 depicts the constructional aspects of the mating slots (10d, 10e) with
respect to the first locking lever (8). As shown in figure 5, the first locking lever is
a rigid structure comprising a first end (8a) and a second end (8b) with shoulder
face (8c). The first end (8a) of the first locking lever (8) is narrow and cylindrical
in shape. The first end (8a) being adapted to be operatively coupled with the first
and second grooves (2a, 2b) of the locking rod (2) during locking/unlocking of the
said wheel lock. The second end (8b) of the first locking lever (8) comprises a flat
shoulder face (8c). The flat shoulder face (8c) is adapted to being operatively
coupled with the mating slots (10d, 10e) of the integral rotating element (10)
during locking/unlocking of the said wheel lock.
Figure 6a shows an isometric view of the protective element (11) of the wheel
lock. The protective element (11) is an L-shaped robust structure comprising a long
arm (11a) and a short arm (11b). The long arm (11a) of the protective element (11)
is adapted to be inserted in the channel (14) from the open end (14b) as depicted in
figure 6b. The long arm (11a) of the protective element (11) comprises a hole
(11c). The hole (11c) is adapted to be in line with the second aperture (13) of lock
box (1) during mounted condition of the protective rod (11) in the channel (14).
The hole (11c) is provided to be operatively engaged with the second locking lever
(9) during locked/unlocked condition of the lock box. The short arm (11b) of the
protective element (11) is adapted to cover the mounting screw (16) of the
mounting bracket (3) during locked condition of the wheel lock thereby limiting
access to the mounting screw (16) when the wheel lock is in locked condition.
Figure 7(a) depicts an isometric view of the wheel lock in locked condition. As
shown in the figure, during locked condition of the wheel lock locking rod passes
through the transverse slot (10a) of the integral rotating element (10). The locking
rod (2) passes through the wheel of the vehicle and the distal end (2d) of the
13
locking rod is received in the first holding slot (17a) of the first holding bracket
(17). Under this condition of the wheel lock, as shown in figure 7 (b) the locking
mechanism (A) is in locked condition and the first end (8a) of the first locking
lever (8) is in received in the first groove (2a) of the locking rod (2). The spring
(15) is in energized state due to being compressed between the side of the integral
rotating element (10) and the flat surface (2e) of the locking rod. The shoulder face
(8c) on the second end (8b) of the first locking lever (8) is received in the mating
slot (10d) of the integral rotating element (10). The integral rotating element is thus
restricted from rotating about its rotational axis. Under this condition of the wheel
lock, the second locking lever (9) is received in the hole (11c) on the protective
element so as to lock the protective rod (11) in the channel (14). The short arm
(11b) covers the mounting screw (16) in this condition to restrict access to the
mounting screw thereby providing safety from tampering with the mounting screw
of the wheel lock.
Figure 8 depicts the sequential unlocking of the wheel lock form locked condition.
Figure 8(a) depicts the wheel lock in locked condition. Upon rotation of the correct
key in the key insertion slot (1b) the locking mechanism (A) is unlocked. The
locking mechanism (A), being operatively coupled with the locking levers retrieves
the first locking lever (8) and the second locking lever (9) with a spring towards
the center (1a) of the said lock box (1). Due to resilient action of the spring (15),
the locking rod is energized to move outwards from the integral rotating element
(10). Due to unlocking of the locking lever with the trapezoidal shape of the first
groove (2a) on the locking rod, the locking rod tends to eject out of the integral
rotating element so that the flat portion (2e) of the locking rod moves away from
the integral rotating element (10). As depicted in figure 8(b) under this condition of
the locking rod, the first groove (2a) of the locking rod is not aligned with the
longitudinal slot (10b) of the integral rotating element resulting in disengagement
of the first end (8a) of the first locking lever (8) with the first groove (2a). As a
result, the shoulder face (8c) at the second end (8b) of the first locking lever is
pushed towards the center (1a) of the lock box. This results in disengagement of
14
the shoulder face (8c) with the mating slot (10d) of the integral rotating element.
As shown in figure 8(c), the flat portion (2e) of the locking rod (2) can now be
pulled away from the integral rotating element (10) until the second groove (2b) of
the locking rod (2) comes in line with the longitudinal slot (10b) of the integral
rotating element. Due to the trapezoidal shape of the second groove (2b) of the
locking rod, it gets engaged with the first end (8a) of the first locking lever (8) so
as to restrict further ejecting of the locking rod (2) out of the integral rotating
element (10). The depth (d2) of the second groove (2b) is lesser than depth (d1) of
the first groove (2a). As a result the face shoulder (8c) continues to remain in
disengaged condition with the mating slot (10d) of the integral rotating element.
Thus, as shown in figure 8(d) the integral rotating element can now be rotated
about its rotational axis by 90 degrees. The rotation of the integral rotating element
(10) is controlled by the stopper (10c) provided on the outer periphery of the
integral rotating element (10). When the integral rotating element (10) is rotated by
90 degrees so that the mating slot (10e) comes in line with the shoulder face (8c) of
the first locking lever (8), the stopper (10c) restricts the further rotation of the
integral rotating element (10). Under this condition of the wheel lock, the locking
rod is in line with a second holding slot (18a) of the second holding bracket (18).
The locking rod is pushed in the downward direction. Due to slope (s) of the
trapezoidal shape of the second groove (2b), the first end (8a) of the first locking
lever (8) allows this downward movement of the locking rod (2). When the first
groove (2a) of the locking rod comes in line with the longitudinal slot (10b) of the
integral rotating element (10), the first groove (2a) once again engages with the
first end (10a) of the first locking lever (10) thereby restricting further movement
of the locking rod in downward direction as shown in figure 8(e). During this
condition of the wheel lock, the distal end (2d) of the locking rod is received in the
second holding slot (18a) of the second holding bracket (18) and wheel lock is said
to be in unlocked condition.
Figure 9 depicts the 3-d view of the said wheel lock in locked and unlocked
conditions. As shown in figure 9(a), the wheel lock is mounted on the shock
absorber near the wheel of the vehicle. The locking rod is received in the second
15
holding bracket and the wheel is free to rotate. In figure 9(b), the wheel lock is in
the locked condition. The locking rod (2) passes through the wheel of the vehicle
to be received in the first holding bracket (17) on the other side of the wheel. The
wheel is in this condition is in jammed condition.
Advantages of the present Invention
The primary advantage of the present invention is the aspect of improved safety. In
the said wheel lock, the mounting screw (16), by which the wheel lock is mounted
on a vehicle is not accessible when the wheel lock is in locked condition. In the
locked condition, the mounting screw is completely covered by the protective rod
(11) making it unapproachable. The opening of this screw can only be achieved by
unlocking the wheel lock by inserting the correct key in the key insertion slot of
the lock box and removing the protective rod (11). Thus, miscreants cannot unlock
the wheel of the vehicle by dismounting the wheel lock from the wheel structure.
Another advantage of the present invention is that while unlocking the wheel lock,
the user does not have to completely pull the locking rod out of the integral
rotating element and place it in a separate holding groove, which in conventional
skew locks is located on the other side of the wheel and hence requires more effort.
In the present wheel lock, the user can pull the locking rod to a maximum limit.
This prevents the locking rod from coming out of the rotating part. The locking rod
can now be simply rotated downwards and then pushed to fix in a holding bracket
located below. Thus, being user friendly.
Yet another advantage of the present invention is that the locking rod cannot be
pulled out of the integral rotating element, hence avoiding misuse/theft of the
locking rod.
16
One more advantage of the present invention is that the rotation of the integral
rotating element is controlled by the stopper. Thus, there is no need for the user to
manually align the locking rod with the first and second holding brackets while
locking and unlocking the wheel lock.
