摘要 | A brake warning apparatus for bicycles is provided, including a lighting device and a switch handle, to be installed on the handles of bicycles. The lighting device includes a light case, a lighting unit and a power unit. The light unit includes at least a switch. The switch handle is partially coupled to the inside of the light case and the rod of the switch handle extending outside the light case is located on the path of the movement of the handbrake of the bicycle when braking the bicycle. When the switch handle is pressed by the handbrake, the rod inside the light case will trigger the switch of the lighting unit so that the lighting device will display the pre-defined lighting condition to achieve the warning effect. | ||||||

说明书全文 | The present invention generally relates to a brake warning apparatus, and more specifically to a brake warning apparatus for bicycles to improve the riding safety. Contemporary people usually lead a busy lifestyle lack of physical exercise. As the oil price gets higher and the environmental awareness grows, more and more people turn to bicycles for short distance transportation in addition to conventional recreational or health purpose in order to reduce the energy consumption and carbon-dioxide production. To provide warning or lighting, most bicycles use a fixed frame and a lighting device. The fixed frame is for fixing a lighting device to the appropriate location on a bicycle, such as the frame, the handle, the back of the seat, and so on. The lighting device provides different lighting conditions, such as blinking, continuous lighting or different color lights for warning or lighting purposes. However, once turned on, the conventional lighting device usually stays in the default lighting condition; thus, lack of interactive or meaningful effects. In addition, when the biker forgets to turn off the lighting device, the battery could use up all the power. Therefore, it is imperative to devise a lighting device that allows interactive warning effects to improve the safety for bicycle riding. The primary object of the present invention is to provide an interactive brake warning apparatus for bicycles; that is, when a biker brakes during riding, the lighting device will laminate to provide warning to improve the safety. Another object of the present invention is to provide a lighting device for the bicycles. The warning apparatus of the present invention is installed on the handle of the bicycles. The lighting device of the warning apparatus may include a plurality of light bulb sets. Some of the light bulb sets can be used a brake warning light, the others can be designed to display various lighting conditions; for example, a continuous light for illumination or a blinking light for warning, and so on. To achieve the above objects, the present invention includes a lighting device, and a switch handle. The lighting device includes a light case, a lighting unit and a power unit. The light case forms a housing space. A part of light case is made of transparent shield. The lighting unit is located inside the light case. The light unit includes a circuit board, at least a light bulb, and at least a switch. The light bulb is located on the circuit board, positioned correspondingly to the transparent shield of light case. The power unit is located inside the light case to provide the power for the lighting unit. The switch handle is partially coupled to inside of the light case and the rod of the switch handle extending outside the light case is located on the path of movement of the handbrake of the bicycle when braking the bicycle. When the switch handle is maneuvered, the rod inside the light case will trigger the switch of the lighting unit so that the lighting device will display the pre-defined lighting condition. The foregoing and other objects, features, aspects and advantages of the present invention will become better understood from a careful reading of a detailed description provided herein below with appropriate reference to the accompanying drawings. The present invention can be understood in more detail by reading the subsequent detailed description in conjunction with the examples and references made to the accompanying drawings, wherein: Lighting device 1 includes a light case, a lighting unit 3 and a power unit 4. Light case 2 forms a housing space 21 for housing aforementioned components. A part of light case 2 is made of transparent shield 22. Lighting unit 3 is located inside light case 2. Light unit 3 includes a circuit board 31, at least a light bulb 32, and at least a switch 33. Light bulb 32 is located on circuit board 31, positioned correspondingly to transparent shield 22 of light case 2. Circuit board 31 includes related circuit for controlling the lighting condition of light bulb 32, such as continuous illumination or periodic blinking. Switch 33 is also located on circuit board 31, but is located on different surface from light bulb 32. Power unit 4 includes at least a battery for providing power to lighting unit 3. Switch handle 5 is partially coupled to inside of light case 2, and the coupling position is located near to switch 33. The rod of switch handle 5 extending outside the light case is located on the path of movement of handbrake 11 of handle 100 of the bicycle when braking the bicycle. When switch handle 5 is moved by handbrake 11, the part of the rod of switch handle 5 located inside light case 2 will trigger switch 33 so that light bulb 32 of lighting unit 3 will illuminate to achieve warning effects. Light bulb 32 of lighting unit 3 is preferably LED, and the LED can be of different colors. The plurality of light bulbs in the present embodiment is only for warning effect and activated by switch 33. However, the use of light bulbs is not limited to the present embodiment. For example, a plurality of light bulbs can be divided into different groups, controlled by different switches. Each group of light bulbs can have different projecting angle; for example, when projecting light towards the front, the light bulbs can act as headlight, the light bulbs blinking toward the sideway can act as warning light. As shown in For convenience of use, brake warning apparatus 200 of the present invention can be removed from and re-installed on handle 100. As shown in As shown in Although the present invention has been described with reference to the preferred embodiments, it will be understood that the invention is not limited to the details described thereof. Various substitutions and modifications have been suggested in the foregoing description, and others will occur to those of ordinary skill in the art. Therefore, all such substitutions and modifications are intended to be embraced within the scope of the invention as defined in the appended claims. |
