Description

1280929 IX. DESCRIPTION OF THE INVENTION: TECHNICAL FIELD OF THE INVENTION The present invention relates to the field of bicycles, and more particularly to a self-propelled handlebar assembly structure. [Prior Art] 7 Racing bicycle is a bicycle designed for speed competition. Its material, shape, ergonomics and physical principles have successfully reduced the resistance caused by self-driving, and achieved the goal of increasing the speed of the bicycle.

The special components of the racing bicycle are quite numerous, and the present invention is directed to the improvement of the structure of the bicycle handle. Please refer to the first figure, and now the handle structure of the conventional racing bicycle and The shortcomings are further explained. The driving hand and the auxiliary grip are as shown in the first figure, which is a conventional racing type self-propelled structure, which comprises a riser (1 〇), a handle body (11), a (1 2 ) and an auxiliary frame (1 3 ). ). One end of the riser (10) is connected to the bicycle body, and the other end of the 5 1280929 forms a semi-cylindrical surface (] 01), and the center of the handle body (π) is placed on the semi-cylindrical surface. (1〇1), and the other semi-cylindrical cover (102) corresponding to the semi-cylindrical surface (1〇1) fits the handle body (11), supplemented by screws to the semi-cylindrical surface (101) and the semi-cylindrical The cover (1〇2) is locked, and the handle body (11) is fixed to the riser (10). > The handle body (11) is provided with armrests (丨丨丨) on both sides of the body, and an auxiliary grip is respectively arranged at equal distances on both sides of the joint between the handle (11) and the official (1 〇). (12), the auxiliary grip (12) and the handle body (1〇) are fixed at an end portion having an arcuate recess (121) conforming to the handle body (1〇) shape, and the two The arcuate recess (121) is disposed on the handle body (10), and the auxiliary grip (丨2) is fixed to the handlebar by the two arcuate covers (122) corresponding to the two arcuate recesses (121) On the body (1 〇). The auxiliary frame (13) is coupled to the auxiliary grip (12) by a coupling member (131), respectively. According to the above-described racing bicycle handlebar structure, the armrest portion (111) of the handle body (10) is held by the user at normal speed, but is held by the user at the armrest portion (丨丨丨). When the hands are opened and the distance between the armrests (111) is the same, the driving of the bicycle in this position will generate a large wind resistance. Therefore, the t user needs to travel at a higher speed of 6 1280929, and the hand can be converted. To the auxiliary grip with a small spacing - (12), Ya can place the elbow on the auxiliary frame (13), the auxiliary grip (12) and the auxiliary frame (13) not only give the user's hands Clamped to the chest to reduce wind resistance, and the auxiliary grip (12) is also better than the armrest

Oil) protrudes from the body of the car, allowing the user to naturally bow when in use, and the overall performance is better, which can effectively reduce the wind resistance and increase the speed of the bicycle. • However, the conventional racing bicycle handlebar structure must be provided with an auxiliary grip and an auxiliary frame on the handle body. The components are more complex, and the assembly cost increases the cost of the assembly. Therefore, in this technical field, g-type bicycle cyclist combination structure, can achieve the (four) single component instead of the racing type of two types of handles, and can maintain the two handles [Embodiment] The purpose of the present invention is to provide a bicycle handlebar set. Poisonous, can be used to structure the structure of the racing bike. Another object of the present invention is to provide a bicycle handlebar 1280929 with a 'sigma structure that can be easily converted into a different racing bicycle handle structure. According to the above and other objects, the present invention provides a bicycle handlebar assembly structure which is formed by pivoting at least two hand members, and the pivoting portion of the mouthpiece member has at least one toothed portion, and the teeth are combined.

The purpose of the multifunctional bicycle handlebars. [Embodiment] In order to make the bicycle handle assembly structure of the present invention more clarified, the following will be described in detail with reference to the drawings. Please refer to the second and third figures, which are exploded views and structural diagrams of an embodiment of the bicycle handlebar assembly structure of the present invention. In the bicycle handle assembly structure of the embodiment, the left hand 1280929 includes (2), the right handle (3), the tightening member (4), the front tube (5), the front (6), and the quick release. Group (7).

In the bicycle handle assembly structure of the embodiment, the self-handle is divided into a left-hand handle (2) and a right-hand handle (3), and the left-hand handle (?) is a grip (21) and a pivoting portion (22). The pivoting portion (22) is connected to the grip (2)) as an empty cylinder, and the ends 4 (221) (222) of the _ portion (22) are plane and outwardly tapered torus, respectively =, the toothed handle (3) is formed by the grip (31) and the pivoting portion (32) centered on the center line of the blessing portion (22): the 'polar transfer paste' is connected to the grip (8) as a The hollow cylinder, the end portion (321) of the pivot portion (32) has a torus corresponding to (222) - a person (10))... a tapered torus, and another end (32, : ^, , The spring is centered with a tooth pattern (33) (34). (4)) Beam:: (4) is a ring member' ring portion (10) has an opening integral shape:) symmetrical projections and rings at the ends of the two sides The locking portion (42) (43) of the portion _, the locking portion (42) (43) is coupled to each other by the 1280929 (45), and the left handle (3) and the tightening member (4) are pivoted. Next, the three-threaded screw (70) of the quick-release group (7) is screwed with the inner screw (71) provided in the front (6), thereby pressing the left-hand handle and the right-hand handle (3)' They are engaged with each other and fixed to the front tube (5). In this embodiment, the end portion (222) of the left handle (2) is an outwardly tapered annulus, and the end portion (32ι) of the right handle (3) is an inwardly tapered annulus. The two are formed to be concave-convex with each other, and the end portion (322) of the right-hand handle (2) and the end portion (401) of the tightening member (4) are also configured to be concave-convex with each other.

The above is an embodiment of the bicycle handlebar assembly structure of the present invention. Hereinafter, the operation mode of the bicycle handlebar assembly structure of the present invention will be further described with reference to the fourth and fifth figures. Referring to the fourth and fifth figures, in the self-assembling structure of the present invention, the handle can be straight, and a racing handle (8) can be added to the end of the handle. When the user needs to adjust the handle of the bicycle, only = the three-threaded screw (7.) of the quick release group (7) causes a space to loosen the original 1280929 fixed member, and then rotate the right handle (3) to In the proper position, tighten the left hand: (2) and adjust the bicycle handle. Tight second, sentence silk (10)’

According to the bicycle handlebar assembly structure of the present invention, the components are combined into a handlebar, and the handles of the handles are pivoted in a toothed manner, and the quick release group is used to perform the handlebars. It can be fixed on the car body and can be adjusted according to the needs of the user, and it becomes a simplified racing bicycle handle design that is easy to operate.
