Patent Description:
Recently, riding bicycles has become a favorite leisure activity for many people. In addition to riding the bicycle in the daytime, many people also like to ride the bicycle at night. For the consideration of riding safety, bicycle light is one of necessary additional devices.

The conventional bicycle light needs to be clamped on the head, handlebar, or handle of the bicycle through a clamp. However, the bicycle light and the clamp have a certain weight. If the user fails to install the bicycle light at the center of the bicycle head, the weight of the bicycle light and the clamp easily affects the maneuverability of the bicycle during riding. Also, the currently existing bicycle light not only affects the maneuverability during riding, but also is directly exposed to the environment. Therefore, the conventional bicycle light is usually vulnerable to wind and rain.

Besides, the currently existing bicycle light mainly provide lighting of the front for the rider to identify the road conditions at night and in dense fog. However, due to the relatively limited range of light beam projected by the bicycle light, the existing bicycle light fails to effectively notify the vehicles behind to slow down. Therefore, bicycle riders usually need to install additional lights or reflectors at the rear of the bicycle to remind the vehicles behind to slow down in time.

Furthermore, the conventional bicycle handgrip is mostly shaped in a circular tube. Therefore, the riders only hold the handgrip in a single direction and is unable to adjust the gripping angle and position according to their riding habits. Such gripping limitation easily causes discomfort during the riding process.

In order to improve the issues of bicycle light above, <CIT> shows the preamble of claim <NUM> and discloses a LIGHTING DEVICE FOR VEHICLES, PARTICULARLY BICYCLES, which includes an illumination device and a cover glass to be disposed on a bicycle.

Also, <CIT> discloses an indication member, an assistant handgrip and bicycle, including an indication body and an indication light circuit, wherein the indication body is connected to the clamp structure of the bicycle handgrip.

To improve the issues above, the present invention discloses a bicycle handgrip device which provides a lighting function and is able to be gripped in different directions, allowing the user to adjust the gripping positions according to user's demand.

For achieving the aforementioned objectives, the present invention provides a bicycle handgrip device, comprising:.

With such configuration, the present invention contains the light in the handgrip to prevent the weight gain on the bicycle head. Therefore, the present invention resolves the issue of the installation method of the conventional bicycle light which causes the center of gravity thereof to be unstable.

Also, the light of the present invention projects the light beam toward the ground surface, which provides illumination to both the front and the rear directions, improving the riding safety, and improving the issue of the conventional bicycle light which can only project the light beam forward and fails to warn the vehicles behind. Besides, the light is a far-distance and close-distance warning light, so as to reduce the discomfort cause by glare upon the drivers or riders behind.

Furthermore, the first handgrip is perpendicular to the second handgrip, providing different gripping directions to the user, allowing the user to adjust the gripping positions according to different habits and demands, also lowering habitual motion fatigue. Therefore, the present invention improves the issue of the conventional handgrip providing only a single gripping direction which fails to meet the habit of the user.

The aforementioned and further advantages and features of the present invention will be understood by reference to the description of the preferred embodiment in conjunction with the accompanying drawings where the components are illustrated based on a proportion for explanation but not subject to the actual component proportion.

The directional terms of, for example, "up", "down", "front", "rear", "left", "right", "inner", "outer", and "side" are only used herein for illustrating the relative directions shown in the drawings. Therefore, the directional terms are applied for the purpose of illustration and understanding of the present invention, instead of limiting the present invention.
