1. Technical Field
The present invention relates to bicycle parts, and more particularly, to a detachable accessory carrier for a bicycle, wherein the detachable accessory carrier can be easily attached to and detached from the frame tube of the bicycle.
2. Description of Related Art
Generally, for minimizing unnecessary burdens and thereby maximizing cyclists' performance, BMX (bicycle motocross) bikes are made as brief as possible. As can be seen in the market, BMX bicycles, unlike bicycles made for other purposes, usually have no accessory carriers for carrying accessories such as a water bottle. This is inconvenient for normal riding and limits a BMX bicycle to a single purpose. On the other hand, track bicycles typically come without brakes, so they have to be additionally equipped with a brake set for normal riding.
For attaching additional accessories to such specialized bicycles for facilitating their normal use, it is necessary to provide an accessory carrier that can be easily attached to and detached from a bicycle frame, wherein when detached from the bicycle frame, the accessory carrier only leaves a fixed seat conformable to the periphery of the bicycle frame, so the fixed seat will not interfere with the cyclist's riding or scrape the cyclist's skin.
Therefore, the present invention proposes a detachable accessory carrier for a bicycle. The detachable accessory carrier can be easily attached to a frame tube of the bicycle for carrying an external object. The detachable accessory carrier can be detached from the frame tube with only a fixed seat left on the frame tube. Since the fixed seat is shaped conforming to the periphery of the bicycle frame, it will not interfere with the cyclist's riding or scrape the cyclist's skin.
According to the present invention, the detachable accessory carrier is composed of a fixed seat, a positioning member and a fastener. The fixed seat has a positioning portion and a fixing portion communicated mutually. The positioning member has an inserting portion that includes a propping portion corresponding to the fixing portion so that when the inserting portion of the positioning member is assembled to the positioning portion of the fixed seat, the fastener can be coupled with the fixing portion and abut against the propping portion of the positioning member, thereby detachably fixing the whole detachable accessory carrier reliably to the frame tube of the bicycle.
The effect primarily achieved by the present invention is that the detachable accessory carrier can carry an external object for meeting a cyclist's need and can be mostly detached from the frame tube of the bicycle with only the fixed seat left on the frame tube so the fixed seat conforming to the periphery of the bicycle frame can ensure the cyclist from operational interference and skin scrape.
In addition, according to the present invention, the positioning portion and the fixing portion have axes thereof intersecting in an angle ranging between 0 and 90 degrees, so the fixed seat can be downsized.
The invention as well as a preferred mode of use, further objectives and advantages thereof will be best understood by reference to the following detailed description of illustrative embodiments when read in conjunction with the accompanying drawings, wherein:
Referring to
The bicycle frame 1 has the tube 10 pre-bored with a radially opened bore 11. The fixed seat 20 includes a main body 201 shaped to be received in the bore 11 of the frame tube 10. The main body 201 has a rim 202 shaped according to a periphery of the frame tube 10 of the bicycle for facilitating close contact between the main body 201 and serving to hold the main body 201 partially exposed at the periphery of the frame tube 10. The fixed seat 20 is fixed to the tube 10 by means of welding. The fixed seat 20 has a positioning portion 21 in the form of a non-threaded hole and a fixing portion 22 in the form of a threaded hole extending in different radial directions of the frame tube 10 and communicating with each other. The positioning portion 21 and fixing portion 22 have axes thereof intersecting in an angle ranging between 0 and 90 degrees while the positioning portion 21 and the fixing portion 22 are internally communicated with each other.
The positioning member 30 has one end formed as an inserting portion 31 that has a columnar shape, so that the inserting portion 31 can be inserted to the hole formed on the positioning portion 21 in the radial direction of the frame tube 10 where the positioning portion 21 extends. The inserting portion 31 includes a propping portion 32 that corresponds to the fixing portion 22 when the inserting portion 31 is set in the positioning portion 21.
The fastener 40 may be a screw or a threaded bolt that can be coupled with the fixing portion 22 in a screwed manner.
Now referring to
According to the present invention, at an end of the positioning member 30 opposite to the end having the inserting portion 31, a bracket of a brake set (as shown in
As shown in
The present invention has been described with reference to the preferred embodiments and it is understood that the embodiments are not intended to limit the scope of the present invention. Moreover, as the contents disclosed herein should be readily understood and can be implemented by a person skilled in the art, all equivalent changes or modifications which do not depart from the concept of the present invention should be encompassed by the appended claims.
