The present disclosure, in general, relates to the field of vehicles. Particularly, but not exclusively, the present disclosure relates to handlebars of vehicles. Further, embodiments of the present disclosure relate to a handlebar and a handlebar assembly for a vehicle. Furthermore, embodiments of the present disclosure also relate to a method of manufacturing said handlebar.
BACKGROUND OF THE DISCLOSURE
[002] Vehicles such as, but not limited to, two-wheelers, three-wheelers, and motorcycles (including two-wheeled, three-wheeled, and four-wheeled motorcycles) generally include a handlebar for steering and maneuvering of the vehicles. Handlebar is a tube-shaped component comprised in a motorcycle's steering mechanism. In addition to performing steering function, handlebars may be configured to support mounting of components such as, but not limited to, throttle, clutch, horn, brake, light control buttons/switches, and rear-view mirrors. Handlebars may be configured to support at least a part of rider's weight and may be configured to provide posture support for the rider. Motorcycle handlebars are generally formed by bending and shaping of a metallic tube made of material such as, but not limited, steel. Handlebars are subjected to higher magnitude of stress. Further, handlebars may suffer accidental impacts during riding of the motorcycle. Hence, it is essential that the handlebar be configured to withstand such high stresses and accidental impacts during operation of the motorcycle.
[003] To comply with above-described requirements of withstanding higher stresses and accidental impacts, metallic materials with high shear strength and impact resilience may be used in making handlebars. Alternatively, the handlebar may be made of solid bars instead of tubes. On the other hand, thickness and cross-section of the tube used in making handlebar may be increased to achieve desired stress and impact resistance. However, a major drawback associated with above approaches is that there will be significant increase in weight of the handlebar. Such
increase in weight of the handlebar may compromise handling and maneuverability aspects of the handlebar. Further, operating/handling of increased weight handlebar may be physically demanding and strenuous to the rider. Furthermore, usage of such heavy and bulky handlebars in a motorcycle may also decrease fuel efficiency of the vehicle and may result in significant increase in operational costs.
[004] With advent of technology and to overcome above-described drawbacks, handlebars made of light-weight materials such as, but not limited to, aluminum alloys and composite materials have been introduced. However, usage of such light¬weight materials may negatively affect impact resistance requirements and vibration absorption capacity of the handlebars. Moreover, such light-weight handlebars may not be suitable for mounting of components such as, but not limited to, throttle, clutch, horn, brake, light control buttons/switches, and rear-view mirrors. Mounting of such components on light-weight handlebars may damage the handlebars by abrasion and may result in handling difficulties to the rider.
[005] The present disclosure is directed to overcome one or more limitations stated above or any other limitations associated with the conventional configuration of the handlebars used in vehicles.

[053] The various embodiments of the present disclosure have been described above with reference to the accompanying drawings. The present disclosure is not limited to the illustrated embodiments; rather, these embodiments are intended to fully and completely disclose the subject matter of the disclosure to those skilled in this art. In the drawings, like numbers refer to like elements throughout. Thicknesses and dimensions of some components may be exaggerated for clarity.
[054] Herein, the terms "attached", "connected", "interconnected", "contacting", "mounted", "coupled" and the like can mean either direct or indirect attachment or contact between elements, unless stated otherwise.
[055] Well-known functions or constructions may not be described in detail for brevity and/or clarity. As used herein the expression "and/or" includes any and all combinations of one or more of the associated listed items.
[056] The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the disclosure. As used herein, the singular forms "a", "an" and "the" are intended to include the plural forms as well, unless the context clearly indicates otherwise. It will be further understood that the terms "comprises", "comprising", "includes" and/or
"including" when used in this specification, specify the presence of stated features, operations, elements, and/or components, but do not preclude the presence or addition of one or more other features, operations, elements, components, and/or groups thereof.
[057] While considerable emphasis has been placed herein on the particular features of this disclosure, it will be appreciated that various modifications can be made, and that many changes can be made in the preferred embodiments without departing from the principles of the disclosure. These and other modifications in the nature of the disclosure or the preferred embodiments will be apparent to those skilled in the art from the disclosure herein, whereby it is to be distinctly understood that the foregoing descriptive matter is to be interpreted merely as illustrative of the disclosure and not as a limitation.
EQUIVALENTS
[058] With respect to the use of substantially any plural and/or singular terms herein, those having skill in the art can translate from the plural to the singular and/or from the singular to the plural as is appropriate to the context and/or application. The various singular/plural permutations may be expressly set forth herein for sake of clarity.
[059] It will be understood by those within the art that, in general, terms used herein, and especially in the appended claims (e.g., bodies of the appended claims) are generally intended as "open" terms (e.g., the term "including" should be interpreted as "including but not limited to," the term "having" should be interpreted as "having at least," the term "includes" should be interpreted as "includes but is not limited to," etc.). It will be further understood by those within the art that if a specific number of an introduced claim recitation is intended, such an intent will be explicitly recited in the claim, and in the absence of such recitation no such intent is present. For example, as an aid to understanding, the following appended claims may contain usage of the introductory phrases "at least one" and "one or more" to introduce claim recitations. However, the use of such phrases
should not be construed to imply that the introduction of a claim recitation by the indefinite articles "a" or "an" limits any particular claim containing such introduced claim recitation to inventions containing only one such recitation, even when the same claim includes the introductory phrases "one or more" or "at least one" and indefinite articles such as "a" or "an" (e.g., "a" and/or "an" should typically be interpreted to mean "at least one" or "one or more"); the same holds true for the use of definite articles used to introduce claim recitations. In addition, even if a specific number of an introduced claim recitation is explicitly recited, those skilled in the art will recognize that such recitation should typically be interpreted to mean at least the recited number (e.g., the bare recitation of "two recitations," without other modifiers, typically means at least two recitations, or two or more recitations). Furthermore, in those instances where a convention analogous to "at least one of A, B, and C, etc." is used, in general such a construction is intended in the sense one having skill in the art would understand the convention (e.g., "a system (100) having at least one of A, B, and C" would include but not be limited to systems that have A alone, B alone, C alone, A and B together, A and C together, B and C together, and/or A, B, and C together, etc.). In those instances where a convention analogous to "at least one of A, B, or C, etc." is used, in general such a construction is intended in the sense one having skill in the art would understand the convention (e.g., "a system (100) having at least one of A, B, or C" would include but not be limited to systems that have A alone, B alone, C alone, A and B together, A and C together, B and C together, and/or A, B, and C together, etc.). It will be further understood by those within the art that virtually any disjunctive word and/or phrase presenting two or more alternative terms, whether in the description, claims, or drawings, should be understood to contemplate the possibilities of including one of the terms, either of the terms, or both terms. For example, the phrase "A or B" will be understood to include the possibilities of "A" or "B" or "A and B."
[060] In addition, where features or aspects of the disclosure are described in terms of Markush groups, those skilled in the art will recognize that the disclosure
is also thereby described in terms of any individual member or subgroup of members of the Markush group.
[061] While various aspects and embodiments have been disclosed herein, other aspects and embodiments will be apparent to those skilled in the art. The various aspects and embodiments disclosed herein are for purposes of illustration and are not intended to be limiting, with the true scope and spirit being indicated by the following claims.
