Combination structure of bicycle handlebars and auxiliary handlebars

Abstract

A combination structure of bicycle handlebars and auxiliary handlebars is disclosed. This combination structure is designed in pairs and integrated onto the two sides of the handlebars, which are laterally close to the center. The handlebars have a first longitudinal axis along their center. Each combination structure includes: a positioning seat, a base, and a bracket. The positioning seat is disposed on the handlebars and has a second longitudinal axis. The base is assembled above the positioning seat, and the bracket is assembled above the base. The outer side of the bracket has a sleeve hole along its longitudinal direction for securing the rear section of the auxiliary handlebar, and this sleeve hole has a third longitudinal axis. Specifically, the second longitudinal axis of the positioning seat and the first longitudinal axis of the handlebar center are not parallel, forming an angle difference. The auxiliary handlebar is mounted on the bracket... The mounting hole of the segment is not parallel to the second longitudinal axis of the positioning seat, thus forming an angle difference. With the above structure, when the paired auxiliary handlebars are fixed to the bracket at the rear, they will form a triangular structure with the front section. This provides a wider shoulder width for the rider than the width of the paired auxiliary handlebars located on the two sides near the center of the handlebar. The arms of the rider's upper body on both sides of the shoulders and the hands extending from the arms to the front of the auxiliary handlebars also form a triangular shape. This provides an ergonomic design that maintains riding posture comfort and reduces rider's physical exertion.

Claims

1. A combination structure of bicycle handlebars and auxiliary handlebars, comprising: The device comprises a handle, two positioning seats, two bases, two supports, and two auxiliary handles. The handle has a first longitudinal axis running longitudinally along its center. The two positioning seats are located laterally on either side of the handle near the center, each with two through holes arranged longitudinally in a front-back configuration, and a second longitudinal axis running along that axis. Each base is positioned above a positioning seat on the handle, and also has two through holes arranged front-back corresponding to the two through holes on the positioning seat. Its top surface has an arc-shaped recess with a circular arc radius. Each of the two brackets includes: a connecting seat and an adjusting seat. The connecting seat has a sleeve hole on its outer side, and the sleeve hole has a third longitudinal axis. The adjusting seat is located at the bottom of the connecting seat of the bracket. The bottom surface of the adjusting seat has an arc-shaped protrusion with a perfect circle arc, so as to make a concave-convex fit with the arc-shaped concave part on the top surface of the base. The bottom section of the adjusting seat also has two long slots arranged longitudinally in front and behind at the opposite position of the two through holes provided on the base. An inserting hole is provided from one side of the adjusting seat toward the two long slots arranged in front and behind, so that each inserting hole provides a locking pin with a locking hole for insertion and positioning. Finally, two angle adjusting bolts are inserted from the bottom end of the two through holes arranged in front and behind on the positioning seat of the handle, through the corresponding through holes provided on the base, and into the two long slots arranged in front and behind in the adjusting seat of the bracket, and locked with the locking holes on the two locking pins. The two auxiliary handles are arranged in pairs. The rear section of each auxiliary handle is fixed to the bracket by a sleeve hole on the outer side of the bracket's connecting seat, while the front section is for the rider's hand to grip. With the above structure, the second longitudinal axis of the positioning seat and the first longitudinal axis of the center of the handle are not parallel to each other, forming an angle difference. The third longitudinal axis of the sleeve hole provided on the bracket for fixing the rear section of the auxiliary handle is also not parallel to the second longitudinal axis of the positioning seat, forming an angle difference.

2. The combination structure of the bicycle handlebars and auxiliary handlebars as described in claim 1, wherein, The second longitudinal axis of the positioning seat is not parallel to the first longitudinal axis of the center of the handle, forming an angle difference. The third longitudinal axis of the mounting hole provided on the bracket for fixing the rear section of the auxiliary handle is also not parallel to the second longitudinal axis of the positioning seat, forming an angle difference. This means that when the paired auxiliary handles are fixed to the bracket at their rear section, they will form a triangular structure with their front section, which is inwardly recessed towards the first longitudinal axis of the center of the handle.

3. The combination structure of the bicycle handlebars and auxiliary handlebars as described in claim 1, wherein, The rear section of the auxiliary handle is a cylindrical tube that is fitted into a longitudinally provided socket on the outside of the bracket's connecting seat.

4. The combination structure of the bicycle handlebars and auxiliary handlebars as described in claim 1, wherein, The auxiliary handlebar has an upward-sloping front section for the rider to grip.

5. The combination structure of the bicycle handlebars and auxiliary handlebars as described in claim 1, wherein, The base is roughly trapezoidal in shape.

6. The combination structure of the bicycle handlebars and auxiliary handlebars as described in claim 1, wherein, The top surface of the bracket is fitted with a protective seat.

7. The combination structure of the bicycle handlebars and auxiliary handlebars as described in claim 6, wherein, The bracket has several parallel locking holes on the top surface of the mounting base and several parallel connecting holes on the protective base. These connecting holes correspond to the several parallel locking holes on the top surface of the mounting base. The protective base is fixed to the top surface of the mounting base by bolts passing through the connecting holes and locking holes.
