Description:FIELD OF THE INVENTION
[001] The present invention relates to a brake assembly for a vehicle. More particularly, the present invention relates to a brake assembly having a parking brake lever as well as brake lever adjusting mechanism.

BACKGROUND OF THE INVENTION
[002] In prior arts, brake assemblies with parking brake lever have been known. Also, brake assemblies with brake lever adjustment mechanisms have been known in the art. In the prior art disclosing parking brake levers, the parking brake levers have been provided for drum brake assemblies. In conventional drum brake assemblies, a brake lever is actuated in a direction of a rider of the vehicle to apply complete braking to lock the vehicle. However, considering wear of a brake liner, a brake cable is required to be adjusted to ensure intended design free-play. In absence of the same, the brake lever will relax in holding the wheel / vehicle against gravity effect on slopes. This will give difference in braking and actuating position of parking lever brake, which results in an ineffective holding of wheel (improper braking).
[003] Prior arts also do not disclose parking brake levers for brake assemblies having hand control disc brakes, adjustable brake levers or a combination of hand control disc brakes and adjustable brake levers owing to challenges identified in designing of such brake assemblies. One of the challenges faced in such a design is hand reach variation for parking brake lever while it is designed to function properly at all conditions of adjusted positions of brake lever. Another challenge is variations in functionality of brake lever (too tight or too loose) while it is designed to access consistent hand reach to brake lever. In view thereof, there is a compromise in achieving consistencies and reliabilities of both hand reach and functionalities of the brake lever. In other words, it has been difficult to design a brake assembly with both parking brake lever and brake lever adjustment mechanism owing to accessibility issue of hand reach to parking brake lever at different adjustment positions of main brake lever, issues in parking brake functionalities at different adjustment positions of adjustable brake lever and technical compromise in addressing conflicting customer requirements owing to either one or both of the above-mentioned issues.
[004] In view of the foregoing, there is a need felt to overcome at least the above-mentioned disadvantages of the prior arts and provide a simple, cost-effective and reliable brake assembly with features of both the parking brake lever as well as brake lever adjusting mechanism which ensures accurate braking operations at all positions of the brake lever.

SUMMARY OF THE INVENTION
[005] In one aspect of the present invention, a brake assembly for a vehicle is shown. The brake assembly comprises a primary brake lever, a secondary brake lever, a primary brake lever adjustment mechanism and a parking brake lever. The secondary brake lever is operably connected to the primary brake lever and a piston of a master cylinder body of a brake system. The master cylinder body is disposed on a handlebar assembly of the vehicle and is operably connected to a wheel of the vehicle such that movement of the piston in the master cylinder body controls braking operation of the vehicle. The primary brake lever adjustment mechanism is rotatably mounted on the primary brake lever. The primary brake lever adjustment mechanism is operably connected to secondary brake lever. The primary brake lever adjustment mechanism is capable of being rotated at one or more pre-defined angles. The rotation of the primary brake lever adjustment mechanism at one or more pre-defined angles results in movement of the primary brake lever to one or more positions with respect to a handle disposed at an end of a handlebar assembly of the vehicle. The parking brake lever is mounted on the primary brake lever and adapted to be rotated and engaged with a receiving arm of the master cylinder body for parking the vehicle. The extent of rotation of the parking brake lever for engagement with the receiving arm is dependent on the one or more positions of the primary brake lever.

The second end of the parking brake lever comprises a first arm and a second arm extending in a direction perpendicular to a longitudinal axis (A-A) of the cylindrical body of the parking brake lever. In one non-limiting example, the first arm and the second arm form a substantially L-shaped structure. The second arm is at a higher elevation than the first arm when viewed in a longitudinal or lateral direction of the vehicle. To enable parking of the vehicle, the primary brake lever is actuated in a direction towards the handle of the vehicle, the first arm of the parking brake lever is operated by the rider of the vehicle and the second arm is engaged with the receiving arm of the master cylinder body. The second arm is engaged in a receiving portion of the receiving arm. The receiving portion is adapted to engage an end of the second arm of parking brake lever. In one non-limiting example, the receiving portion is arch-shaped cut out portion facing the rider of the vehicle. It is to be understood that, on actuation of the primary brake lever towards the handle of the vehicle, the piston is actuated by an actuating mechanism operably connected to the secondary brake lever.
[007] In an embodiment, the one or more positions of the primary brake lever are a first position, a second position and a third position. The second position is a mean position of the primary brake lever. The first position is a position away from the mean position in a direction towards the handle of the handle bar assembly and the second position is away from the mean position in a direction away from handle of the handlebar assembly.

DETAILED DESCRIPTION OF THE INVENTION
[011] Various features and embodiments of the present invention here will be discernible from the following further description thereof, set out hereunder.

[013] In the present invention, a longitudinal axis of the vehicle refers to a front to rear axis relative to the vehicle, defining a vehicle longitudinal direction while a lateral axis of the vehicle refers to a side to side, or left to right axis relative to the vehicle, defining a vehicle width direction. Also, it is to be understood that the phraseology and terminology used herein is for the purpose of description and should not be regarded as limiting. for the purpose of description and should not be regarded as limiting. Arrows provided in the top right corner of figures depicts direction with respect to the vehicle, wherein an arrow Rt denotes right direction, an arrow Lt indicates left direction, an arrow Up denotes upward direction, an arrow Dw denotes downward direction of the vehicle.
[014] The term “vehicle” in the present invention refers to saddle type vehicles such as, not being limited to mopeds, scooters, motorcycles having hand operated brake lever assembly. The construction and working of different parts of the vehicle are already known in the art and have been discussed only to the extent they are relevant for the purposes of the present invention.
[015] In Figure 1, a handle 10 of a handlebar assembly 12, a master cylinder body 104 as well as brake lever assembly of the vehicle are shown whereas in Figures 2-5, different views of the brake lever assembly have been shown. The brake lever assembly comprises a primary brake lever 100, a secondary brake lever 102, a primary brake lever adjustment mechanism 106 and a parking brake lever 108. The secondary brake lever 102 is operably connected to a piston of the master cylinder body 104 of a brake system. In one non-limiting example, the brake system is a disc brake system. The construction and operation of the disc brake system is well known in the art and has not been discussed in detail for the sake of brevity. The master cylinder body 104 is disposed on the handlebar assembly 12 of the vehicle. The primary brake lever adjustment mechanism 106 is mounted on the primary brake lever 100. The primary brake lever adjustment mechanism 106 is operably connected to the secondary brake lever 102 such that rotation of the primary brake lever adjustment mechanism 106 results in the adjustment of the piston. In one non-limiting example, rotation of the primary brake lever adjustment mechanism 106 to move the primary brake lever 100 from a second position (SP) (shown in Figure 11) to a first position (shown in Figure 13) will move the piston in a first direction and rotation of the primary brake lever adjustment mechanism 106 to move the primary brake lever 100 from a second position (SP) to a third position (TP) will move the piston in a second direction. The first direction is opposite to the second direction. In order to move the primary brake lever 100 to different pre-defined positions, the primary brake lever adjustment mechanism 106 is rotated at pre-defined angles by a rider of the vehicle. The primary brake lever adjustment mechanism 106 has a rotatable disc 114 which is capable of being rotated at pre-defined angles to move the primary brake lever 100 to different positions. In one non-limiting example, the primary brake lever adjustment mechanism 106 can be rotated at 120 degrees, 240 degrees and 360 degrees to move the parking brake lever at three different positions with respect to the handle 10 of the vehicle. This example should not be construed as limiting and the primary brake lever adjustment mechanism 106 can be rotated at plurality of pre-defined angles to adjust the primary brake lever 100 at plurality of positions with respect to the handle 10 of the vehicle. The parking brake lever 108 is also mounted on the primary brake lever 100. To park the vehicle, the parking brake lever 108 is adapted to be operated by the rider of the vehicle and engaged with a receiving arm 110 of the master cylinder body 104. As the parking brake lever 108 is mounted on the primary brake lever 100, movement of the primary brake lever 100 will also result in movement of the parking brake lever 108 with respect to the handle 10 of the vehicle. The extent of rotation of the parking brake lever 108 to engage with the receiving arm 110 of the master cylinder body 104 will depend on the position of the primary brake lever 100.
[016] In an embodiment, the parking brake lever 108 comprises a cylindrical body 108a which extends between a first end 108d and a second end 108e. The first end 108d of the cylindrical body 108a is adapted to be received on the primary brake lever 100. The second end 108e comprises a first arm 108b and a second arm 108c. The first arm 108b is adapted to be operated by a rider of the vehicle. The second arm 108c is adapted to be engaged with the receiving arm 110 of the master cylinder body 104 for parking the vehicle. The first arm 108b and the second arm 108c are spaced apart at a second pre-defined angle. In a non-limiting example, the first arm 108b and the second arm 108c form a substantially L-shaped structure. The second arm 108c of the parking brake lever 108 is also elevated with respect to the first arm 108b when viewed in longitudinal and lateral directions of the vehicle. It is to be understood that the first arm 108b is at a lower elevation to avoid interaction with the receiving arm 110 of the master cylinder body 104 and also to be proximate to an index finger of the rider of the vehicle so that the rider can operate the first arm 108b using his/her index finger with application of minimum force. The second arm 108c is at a higher elevation as the same is to be engaged with the receiving arm 110 of the master cylinder body 104 for parking the vehicle. The receiving arm 110 of the master cylinder body 104 has a receiving portion 110a. It is to be understood that profile of the receiving portion 110a should align with profile of an end of the second arm 108c of the parking brake lever 108 to enable engagement of the end of the second arm 108c with the receiving portion of the master cylinder assembly 104. In order to park the vehicle, the primary brake lever 100 is actuated towards the handle 10 of vehicle and the first arm 108b of the parking brake lever 108 is operated by the rider of the vehicle to move in a direction towards the handle 10 and engage the second arm 108c of the primary brake lever 100 with the receiving portion 110a of the receiving arm 110. As shown in Figure 2, a pivot of the parking brake lever 108 is located close to a pivot connecting primary brake lever 100 and the secondary brake lever 102. Owing to this construction, any variation in effect of locking of parking brake lever 108 during various adjustment positions of the primary brake lever 100 is minimized significantly. This addresses any technical compromise in achieving conflicting requirements of easy consistent hand reach and reliable functionality of the parking brake lever 108.

The primary brake lever 100 is operably connected to the secondary brake lever 102. The primary brake lever 100 and the secondary brake lever 102 are operably connected using spring 116 and fasteners. The secondary brake lever 102 is also operably connected to the piston of master cylinder body 104 such that, upon actuation of the primary brake lever 108 in a direction towards the handle 10 of the handlebar assembly, the brake system is activated. The primary brake lever adjustment mechanism 106 is mounted on the primary brake lever 100 and is operably connected to the secondary brake lever 102 such that movement of the primary brake lever adjustment mechanism 106 and, therefore, the primary brake lever 100, also results in adjustment of the piston. The parking brake lever 108 is mounted on the primary brake lever 100. The parking brake lever 108 is capable of being operated by the rider of the vehicle. The master cylinder body 104 is disposed on the handlebar assembly 12 of the vehicle. The actuating mechanism 112 is operably connected to the secondary brake lever 102 for actuating the piston.
[023] The master cylinder body 104 comprises a receiving arm 110. The parking brake lever 108 is adapted to be engaged with the receiving arm 110 of the master cylinder body 104 for parking the vehicle. To park the vehicle, the primary brake lever 100 is actuated in the direction of the handle 10 and the parking brake lever 108 is operated by the rider of the vehicle using his/her index finger in a direction towards the handle 10 of the vehicle and engaged with the receiving arm 110 of the master cylinder body 104. The construction of the master cylinder body 104 and the parking brake lever 108 have been discussed in detail in Figure 9 and Figure 10, respectively.
[024] Figure 9 illustrates perspective, top and side views of the master cylinder body 104, in accordance with the embodiment of the present invention.
[025] As shown, the master cylinder body 104 comprises the receiving arm 110. The receiving arm 110 extends in a direction towards an end of the handle 10 of the handlebar assembly 12 of the vehicle. The receiving arm 110 comprises the receiving portion 110a which is adapted to engage with the parking brake lever 108. In one non-limiting example, the receiving portion 110a is an arch-shaped cut out portion facing the rider of the vehicle. For parking the vehicle, the primary brake lever 100 is actuated in the direction of the handle 10 of the handlebar assembly 12 and the parking brake lever 108 is operated by the rider of the vehicle using his/her index finger in a direction towards the handle 10 of the handlebar assembly 12 of the vehicle and engaged with the receiving portion 110a of the receiving arm 110 of the master cylinder body 104.
[026] Figure 10 illustrates perspective, top and side views of the parking brake lever 108, in accordance with the embodiment of the present invention.
[027] As shown, the parking brake lever 108 comprises the cylindrical body 108a which extends between the first end 108d and the second end 108e. The first end 108d of the cylindrical body 108a is adapted to be received on the primary brake lever 100. The second end 108e comprises the first arm 108b and the second arm 108c. The first arm 108b is adapted to be operated by a rider of the vehicle. The second arm 108c is adapted to be engaged with the receiving arm 110 of the master cylinder body 104 for parking the vehicle. In a non-limiting example, the first arm 108b and the second arm 108c form a substantially L-shaped structure. The second arm 108c is also elevated with respect to the first arm 108b when viewed in longitudinal and lateral directions of the vehicle. It is to be understood that the first arm 108b is at a lower elevation to avoid interaction with the receiving arm 110 of the master cylinder body 104 and also to be proximate to the index finger of the rider of the vehicle so that the rider can operate the first arm 108b using his/her index finger with application of minimum force. The second arm 108c is at a higher elevation as the same is to be engaged with the receiving arm 110 of the master cylinder body 104 for parking the vehicle. The receiving arm 110 of the master cylinder body 104 has a receiving portion 110a. It is to be understood that profile of the end of the second arm 108c of the parking brake lever 108 should align with profile of the receiving portion 110a of the receiving arm 110 to enable engagement of the end of the second arm 108c with the receiving portion 110a of the master cylinder body 104. In order to park the vehicle, the primary brake lever 100 is actuated towards the handle 10 and the first arm 108b of the parking brake lever 108 is operated by the rider of the vehicle to move in a direction towards the handle 10 and engage the second arm 108c of the parking brake lever 108 in the receiving portion 110a of the receiving arm 110 to enable parking of the vehicle.
[028] Figure 11 illustrates actuation of the primary brake lever 100 from a second position (SP) to a parking state, in accordance with the embodiment of the vehicle.
[029] As shown, the parking brake lever adjusting mechanism 106 is set at the second position (SP). The same is indicated by a number indicated on the parking brake lever adjusting mechanism 106. The second position (SP) is a mean position between the first position (FP) and the third position (TP). In order to park the vehicle, the primary brake lever 100 is actuated from the second position (SP) towards the handle 10 of the handlebar assembly 12 and the first arm 108b of the parking brake lever 108 is operated by the rider of the vehicle to move in a direction towards the handle 10 and engage the second arm 108c of the parking brake lever 108 for parking of the vehicle.
[030] Figure 12 illustrates actuation of the primary brake lever 100 from a third position (TP) to the parking state, in accordance with the embodiment of the vehicle.
[031] As shown, the parking brake lever adjusting mechanism 106 is set at a third position (TP). The same is indicated by a number indicated on the parking brake lever adjusting mechanism 106. The third position (TP) is a position away from the second position (SP) in a direction away from the handle (10) of the handlebar assembly (12). In order to park the vehicle, the primary brake lever 100 is actuated from the third position (TP) towards the handle 10 of the handlebar assembly 12 and the first arm 108b of the parking brake lever 108 is operated by the rider of the vehicle to move in a direction towards the handle 10 and engage the second arm 108c of the parking brake lever to enable parking of the vehicle.
[032] Figure 13 illustrates actuation of the primary brake lever 100 from a first position (FP) to a parking state, in accordance with the embodiment of the vehicle.
[033] As shown, the parking brake lever adjusting mechanism 106 is set at the first position (FP). The same is indicated by a number indicated on the parking brake lever adjusting mechanism 106. The first position (FP) is a position away from the second position (SP) in a direction towards the handle (10) of the handlebar assembly (12). In order to park the vehicle, the primary brake lever 100 is actuated from the first position towards the handle 10 of the handlebar assembly 12 and the first arm 108b of the parking brake lever 108 is operated by the rider of the vehicle to move in a direction towards the handle 10 and engage the second arm 108c of the parking brake lever 108 to enable parking of the vehicle.
[034] In Figures 11-13, it can be clearly seen that the second arm 108c of parking brake lever 108, when engaged / locked, is oriented substantially at a tangent line, which is perpendicular (almost 90° angle) to a radial line connecting the end of the second arm 108c and a pivot of the secondary brake lever 102 and the master cylinder body 104. Owing to this construction, locking force produced during locking condition of parking brake lever 108 upon the primary brake lever 100 and secondary brake lever 102 is set in the same direction of actuation of the primary brake lever 100 and opposite direction of brake lever returning.
[035] The claimed features/method steps of the present invention as discussed above are not routine, conventional, or well understood in the art, as the claimed features/steps enable the following solutions to the existing problems in conventional technologies. Specifically, the technical problem of efficient parking of the vehicle at different position of the primary brake lever is solved by present invention.
[036] In the present invention, the first arm of the parking brake lever is oriented in such a way that at least the index finger of the rider of the vehicle should easily access the first arm to start actuating parking brake lever. The present invention also aims to easily actuate parking brake lever with less effort to lock the parking brake lever for parking the evhicle.
[037] In the present invention, the position, orientation and size of the parking brake lever first arm is made in a such a way that the first arm is actuated by at a single finger (index finger) while keeping other three fingers for actuation of the primary brake lever. The construction of the present invention is such that efficient parking is achieved at all different positions of the primary brake lever. The present invention, therefore, improves ergonomic of the vehicle.
[038] In the present invention, efficiency of the parking brake is improved as parking brake lever is mounted on the primary brake lever and moves along the primary brake lever, thereby eliminating a free play.
[039] In the present invention, the construction of the parking brake lever is simple, reliable and durable. Moreover, said parking brake lever is easy to manufacture as well as assemble.
[040] In the present invention, dedicated master cylinder assembly and caliper assembly are eliminated, thereby reducing number of parts of the brake assembly. Conventionally, a dedicated brake caliper is provided in the rear wheel to actuate the parking brake. The said parking brake lever is connected to the dedicated caliper through plurality of mechanical linkages and uses dedicated master cylinder assembly.
[041] While the present invention has been described with respect to certain embodiments, it will be apparent to those skilled in the art that various changes and modification may be made without departing from the scope of the invention as defined in the following claims.
