Detailed Description

In order to further explain the technical solution of the present invention, the present invention is explained in detail by the following specific examples. Coordinates X, Y, Z in the figure indicate a front-to-back direction, a left-to-right direction, and an up-to-down direction, respectively, where the X-axis arrow points in the forward direction, the Y-axis arrow points in the leftward direction, and the Z-axis arrow points in the upward direction.

As shown in fig. 1-4, a hand-free umbrella for bicycle comprises an umbrella cover 1, a mounting component 2 and a plurality of arc ribs 3, wherein each arc rib 3 extends along the front-back direction and is provided with a head end and a tail end, the head ends and the tail ends of the arc ribs 3 are respectively and movably connected to a steel ring 4, and the arc ribs 3 are arranged along the left-right direction, the umbrella cover 1 is connected to the arc ribs 3, the umbrella cover 1 is switched between an unfolding state and a folding state, the connection mode can refer to the connection mode of the umbrella cover and the ribs in the existing umbrella, the umbrella cover 1 is of a half-football structure in the unfolding state, and the mounting component 2 is used for mounting the hand-free umbrella on a handlebar.

The half football structure is divided into a front portion 11, a middle portion 12 and a rear portion 13, the middle portion 12 being upwardly convex and the front portion 11 and the rear portion 13 extending downwardly. By adopting the structure, the middle part of the umbrella can have a larger shielding space, so that a user can move in the umbrella conveniently, and the comfort level is improved. Umbrella face 1 covers above the cyclist and anterior portion 11 forms the protective surface in the front, and rainwater can slide down along the radian of arc rib 1, can not gather rainwater on the umbrella face, consequently can not influence the sight of cyclist. And the half football structure accords with the aerodynamic principle more, and the air smoothly flows away along the radian of front portion 11, reduces the resistance that the umbrella face received when riding greatly, lets the user ride more easily, safety.

As a first embodiment of the mounting assembly of the present invention, the two bicycle handles are respectively provided with a mounting assembly 2, the mounting assembly 2 comprises a connecting pipe 21 and an extension pipe 22 which are connected, one end of the connecting pipe 21 is connected with the two outermost arc-shaped ribs 3 at the left and right sides, and can be fixed by welding or screws, the other end is connected with the extension pipe 22, the extension pipe 22 can extend and retract along the left and right direction, and the extension pipe 22 is used for being sleeved on the bicycle handle.

When the hand-free umbrella is used, the umbrella cover 1 is unfolded to form a semi-football structure, the two extension tubes 22 on the left side and the right side are positioned at a horizontal position, the extension lengths of the two extension tubes 22 are adjusted according to the width of a bicycle handle, and then the two extension tubes 22 are sleeved and fastened on the handle, so that the installation of the hand-free umbrella is completed. When the umbrella is folded, the arc umbrella ribs 3 at two sides are closed towards the middle direction only by imitating the folding mode of the paper fan, and the use process is simple and quick.

Preferably, the extension tube 22 is made of rubber. The selected rubber material has certain elasticity and deformability, can be sleeved on bicycle handles in various shapes, and can better shrink and sleeve the bicycle handles tightly under the action of the elasticity.
