DESC:FIELD OF INVENTION

The present invention relates to handlebars, particularly to the bicycle handlebars. It also relates to the means of adjusting the handlebar length for providing a suitable ride experience to the cyclist.

BACKGROUND OF THE INVENTION

The rider uses the bicycle to ride on various terrains and rides in different styles and positions. So giving the rider sufficient adjustability in the handlebar control will accentuate the ride quality and provide the most appropriate ride experience. Bicycles are an efficient, inexpensive and environment friendly means of converting mechanical energy into another form, in order to produce self-propelled motion. The main problem faced by most cyclists is the necessity to have to adjust to the same handlebar length and style, while on a ride, or having to change the handlebar every time a different ride experience is sought. Riders may switch between multiple modes like speeding, relaxing and café racing, while in the midst of the ride by simply adjusting the length or flipping the assembly by the horizontal. The present handlebar offerings in the industry only accommodate minimum flexibility in terms of ride types, as they require the cyclist to change the handlebar at the beginning of each ride. This is an inconvenience and causes most riders to abstain from experimenting with different terrains and riding styles. Thus, present systems are inadequate or are of little value for handlebar adjustment in the present day and age.

OBECTS OF THE INVENTION

The primary purpose of the present invention is to provide a handlebar for a bicycle to remedy the flaws and sufferings identified in the prior art. To achieve this purpose, the present invention is comprised of an adjustable bar with at least three modes i.e. narrow bar, mid bar and a wide bar mode which are indicative of the handlebar length, wherein the handle can be flipped for achieving an aggressive low rise posture.

DESCRIPTION OF INVENTION

Cyclists are restricted to one riding style at a time, when it comes to interacting with the handlebar. The handlebar design and length defines the kind of control the cyclist has on how he wishes to maneuver in different riding conditions.

The current handlebar-stem offerings in the market provide for minimum flexibility and cause more inconvenience as they require the cyclist to change the handlebar tube for every different ride type. The SPLIT SPORTS BAR addresses this complication and is designed to provide the cyclist the most suitable ride experience each time his ride demands it.

The invention consists of a handlebar which comprises of three components (Refer Fig 1):

A bicycle handle bar includes a main connecting clamp connected to the bicycle. A first steering tube and a second steering tube correspondingly disposed generally at left end and right end of the main connecting member.

The said steering tubes can be mounted in a slide-able telescopic manner onto the main connecting tube.
The said steering tubes can be clamped thereafter to the corresponding two ends of the main connecting members with a clamp assembly.

Each of the steering tubes can be secured with a corresponding clamp assembly disposed at the ends of the main tubular connecting member. The said steering tubes can be secured through one of the many aforementioned clamping areas, their orientation defining an axis that extends in a direction that is aligned at 5 degrees with the longitudinal axis.

The axis is defined in a manner so as to provide ergonomic advantage to the rider.
As per the invention, accordingly, the main connecting member thus has means of clamping arranged at the ends to have the two steering tubes clamped at either end of the connecting member.
The two steering tubes that are clamped to the connecting member are capable of being slid in either direction when the bolts on the clamps are loosened. This allows for adjustability of the length of the handlebar, by shortening or increasing the distance between the ends to be gripped. The SPLIT SPORTS BAR accommodates multiple modes of adjustability by virtue of its sliding tubes.The different modes can be broadly classified into 3 types – first is “THE NARROW BAR” FIG 4.1, for speed and agility, the “MID BAR” FIG 4.2 is for intermediate posture, and the “WIDE BAR” FIG 4.3 for better control and stability. The slidably extendible and retractable steering tubes with respect to main connecting member provide an improved adjustable handlebar meeting the demand of the cycle rider. Also on flipping the handlebar by the horizontal axis gives the rider a very aggressive low rise posture. Additionally the invention eliminates the usage of a stem (used as a connecting member between the handlebar and steering column) is directly mounted onto the steering column of the fork, giving the rider a direct feedback from the fork.

Hence the SPLIT SPORTS BAR offers the rider the most suitable experience of each ride style he chooses. The two steering tubes may further be provided and engaged through other means of fastening onto main connecting member beyond the clamping means arrangement; though clamping means is most preferred, the invention is not restricted to this fastening arrangement.

Accordingly the adjustable bicycle handlebar in accordance with the present invention includes an adjustable steering tubes adjustable to the selected or suitable handlebar length. This invention provides accordingly an adjustable handlebar which may be adjusted with a simple clamping tool or other suitable fastening means to fit a particular rider.

The adjustable handlebar of the invention is a significant improvement exhibiting an enormous inventive-step over prior art handlebars. It enables easy shift from one length of handle bar to another length which is desired by the rider and extremely advantageous in terms of operation, cost and robustness.

In one aspect bicycle handle bar with adjustable handle bar length by the operator comprising of a connecting means with a main connecting clamp (1a) attached fixedly at its one end onto the bicycle and with the other end extending sideways angularly and outwardly to form a pair of a left and a right handle bar tube (1b, 1c) on either side of the main connecting member. A fastening means (2a, 2b) is disposed at the distant end of each of the handle bar tube. A telescopically slide-able (3a, 3b) steering tube is disposed in a removable and adjustable manner with the said fastening means (2a, 2b) onto each of the two handle bar tubes (1b, 1c). The said arrangement is novel in that the sliding steering tubes allow adjustable length of the handle bar by the operator of the bicycle.

In another aspect of the invention the bicycle handle bar with adjustable handle bar length as described above, has the fastening means (2a, 2b) which may be clamp means or any other fixing means.

In yet another aspect of the invention the left and right handle bar steering tubes (3b and 3c) are positioned at an angle of 5 degrees as against the main connecting members as shown in FIG. 3.1 and 3.2. This provides for increased ergonomic comfort as per the users preference as the handlebar can be placed on to the stem with either the handlebar tubes projecting in or out as shown in the figures 3.1 and 3.2. In other words the handle can be flipped for achieving an aggressive low rise posture.

The invention has been described with examples, embodiments etc. for the purpose of understanding the invention. All the modifications and variations are well within the scope of invention. The applicant intends to rely upon provisional specification and the drawings submitted along with provisional specification.
