Patent Application
20100059638
The present invention relates to a connection device and more particularly, to an accessory connection device for conveniently connecting accessories to bicycles.
There are lots of accessories to be connected to a bicycle such as light set and water bottle, and these accessories are optional parts for the riders and can be connected to the bicycle frame by individual connection devices. The light set is cooperated with an unique connection device and the water bottle is cooperated with another connection device. Therefore, the rider has to purchase several different shapes of connection devices for different accessories.
A conventional connection device for a light set generally includes a light frame which has two arms so as to position a light unit between the two arms. The light frame is secured to the bicycle handlebar and each arm includes a through hole and a notch which is communicates with the through hole. A flexible ring is mounted to the two arms and in contact with light unit. The flexible ring is engaged with the through holes so that the flexible ring does not shift.
A conventional connection device for a water bottle generally includes a base and a frame so that the water bottle can be positioned between the base and the frame. A connection unit includes a first connection member and a second connection member, wherein the first connection member is connected to the base and the second connection member is connected to the frame and adjustable relative to the first connection member. By adjusting the second connection member, the water bottle can be positioned at desired angle.
Both of the two conventional connection devices include too many parts and have only one function for specific accessory. In other words, the parts of the two connection devices are completely different, once one of the parts is missing, the whole connection device cannot be functioned.
The present invention intends to provide a connection device for connection different accessories to bicycle frame by common parts.
The present invention relates to a connection device which comprises at least one first fastener having a first end threadedly connected to a bicycle part, at least one second fastener threadedly connected to a second end of the at least one first fastener, and a connection unit which is connected between the at least one first fastener and the at least one second fastener. The connection unit is designed for different accessories such as light bulb, water bottle or storage bag.
The primary object of the present invention is to provide a connection device for connecting accessories to bicycle frame and the connection device includes less number of parts which can be cooperated with different connection units for different accessories.
The present invention will become more obvious from the following description when taken in connection with the accompanying drawings which show, for purposes of illustration only, a preferred embodiment in accordance with the present invention.
Referring to
The clamping unit 10 includes a first clamp member 11 and a second clamp member 12, wherein the first clamp member 11 is integrally formed with the handlebar stem 40. A clamp space is defined between the first and second clamp members 11, 12 such that the handlebar is secured between the first and second clamp members 11, 12. The first fasteners 20 are threadedly connected to the clamping unit 10 so as to move the first and second clamp members 11, 12 toward each other.
The connection unit 50 is connected between the first fasteners 20 and the second fasteners 30, and includes a light frame 51 which is a U-shaped frame and a light bulb 52 is pivotably connected between two arm plates of the light frame 51. The four second fasteners 30 extend through the light frame 51 and are connected to the first fasteners 20 to fix the light frame 51 to the second clamping member 12 of the clamping unit 10.
By the connection of the first and second fasteners 20, 30, the connection unit 50 can be fixed to the bicycle frame and the connection unit 50 can be designed to have different shapes and functions so as to connect different accessories to the bicycle. It is noted that only the connection unit 50 needs to be changed when connecting different accessories to the bicycle.
While we have shown and described the embodiment in accordance with the present invention, it should be clear to those skilled in the art that further embodiments may be made without departing from the scope of the present invention.
