Description

Anti-theft bicycle rack

The present invention relates to a bicycle frame, and more particularly to an anti-theft bicycle frame capable of having an anti-theft effect.

Because bicycles are environmentally friendly and pollution-free, and the price of oil is high, it has become the best choice for commuters and students to commute. At the same time, riding bicycles is a very healthy leisure activity and has become one of the most popular outdoor sports for modern people.

In order to avoid theft of the bicycle, the rider usually uses a rope with a lock to fix the bicycle to a cylinder for the purpose of anti-theft. The rope is usually entangled and fixed at random during the ride of the rider. On the bicycle or placed on the rider, when the vehicle arrives at the fixed point, the lock is unlocked, and one end of the rope is taken out of the bicycle and wound around a cylinder, and then returned to the lock and buckled. Locked, it can achieve the purpose of anti-theft.

However, such a tamper-evident rope is prone to deformation after being entangled for a long time, and may be knotted and cannot be smoothly untied, so it is extremely inconvenient, and in addition, when the tamper-proof rope is arbitrarily fixed to the bicycle, it also affects As for the overall appearance of the bicycle, if it is placed on the rider, there will be problems that cannot be found.

Accordingly, it is an object of the present invention to provide an anti-theft bicycle frame that is easy to use and that can beautify the appearance of a bicycle.

Therefore, the novel anti-theft bicycle frame includes a vehicle body and an elastic single Yuan, and a rope. The elastic unit is disposed on the vehicle body. The cord is movably bypassing the elastic unit and compressing the elastic unit.

The utility model has the advantages that the elastic unit is used to store the rope along the bicycle shape, and the rope is not deformed and knotted, so that it is convenient to use and can beautify the appearance of the bicycle.

The foregoing and other technical aspects, features and advantages of the present invention will be apparent from the following description of the preferred embodiments of the invention.

Referring to Figures 2 and 3, a preferred embodiment of the anti-theft bicycle frame includes a vehicle body 2, an elastic unit 3, and a rope 4.

The vehicle body 2 includes two vertical risers 21 and two side cross pipes 22 connected to the upright pipes 21, respectively. In the preferred embodiment, the riser 21 is located at the front and is used to connect the handle 11 and the front wheel 12, and the other upright pipe 21 is located at the rear and is used for connecting the seat cushions 13, which are respectively erected from the front. The two sides of the tube 21 extend toward the rear upright tube 21, and the ends extend downward in an arc shape and are provided for the rear wheel 14. The body 2 further includes a support rod 23 spaced apart from the side tubes 22 between the upright tubes 32. Both ends of the support rod 23 are welded to the upright tubes 21, respectively.

The elastic unit 3 is disposed on the side of the upright tube 21 of the vehicle body 2 on which the seat cushion 13 is mounted. In the preferred embodiment, the elastic unit 3 includes a body 31 disposed on the upright tube 21 of the vehicle body 2, The movable member 32 is disposed on the body 31 and is wound by the rope 4, and a set of elastic members 33 are disposed on the body 31 and the movable member 32. The body 31 has a set in the car The large diameter section 311 of the body 2 upright pipe 21, a small diameter section 313 for the movable member 32, and a middle diameter section 312 formed between the large diameter section 311 and the small diameter section 313. The elastic member 33 is a spring and has one end abutting against the large diameter section 311 and the other end being fixed to the movable member 32. The movable member 32 has a recess 321 which is recessed and which is passed around the rope 4. However, the elastic unit 3 can also be a spring piece as long as the elastic force of the rope 4 can be provided.

The rope 4 movably bypasses the elastic unit 3 and compresses the movable member 32 and the elastic member 33. One end 41 of the rope 4 is fixed to one side cross tube 22 of the vehicle body 2, and the other end 42 of the rope 4 is movably disposed on the other side cross tube 22 of the vehicle body 2. In the preferred embodiment, the rope 4 is disposed on the vehicle body 2 by a round buckle 43 and a C-shaped buckle 44. However, the two ends of the rope 4 can also be disposed on the two C-shaped buckles 44. The vehicle body 2, therefore, both ends of the rope 4 can be detached at the same time. What is important is that the rope 4 can also be placed along the riser 21 therein or along the support bar 23.

It is worth mentioning that the preferred embodiment further includes a storage basket 5 disposed in front of the vehicle body 2 for placing articles. The storage basket 5 has a frame 51 connected to the side tubes 22 and a ring frame 52 which is inclined and connected to the frame 51. The bracket 51 is a continuously bent tubular member and has a fixed section 511 which is inverted U-shaped and connected to the lateral cross tubes 22, and two ends of the fixed section 511 respectively extend away from the vehicle body 2 The support section 512, and the two side sections 513 respectively extending upward from the support sections 512, the fixed section 511 is connected to the side cross tubes 22 by a fixing plate 53 and two screws (not shown). The ring frame 52 is continuously bent and connected to the fixed segment 511 and the like The closed tubular member of the flank 513, and the annular frame 52 extends from the fixed segment 511 toward the side joint segments 513 and is inclined downward. In the preferred embodiment, the basket 5 is fixed to the side tubes 22. When the upright tube 21 equipped with the handle 11 is rotated, it does not rotate with it, so that the bicycle is easier to turn.

When riding, one end 41 of the rope 4 is fixed to the circular buckle 43 , and the other end 42 is pulled along the one side of the horizontal tube 22 toward the elastic unit 3 , and bypasses the groove 321 , and then The other side of the horizontal tube 22 is pulled back, and then the other end 42 is fastened to the C-shaped buckle 44. After the rider arrives at the destination to get off the vehicle, the other end 42 of the rope 4 is removed from the C-shaped buckle 44 and surrounds the bicycle and a cylinder (not shown) and then returns to the round buckle 43. At this time, as long as the lock 4 (not shown) is used to lock the two ends of the rope 4 together, the purpose of theft prevention can be achieved.

Of course, it is also possible to use two C-shaped buckles for the two ends of the rope 4 to be fastened. Therefore, the two ends of the rope 4 can be removed, and a lock is arranged around the bicycle and the cylinder, and the anti-theft can also be achieved. purpose.

In summary, the movable member 32 and the elastic member 33 are used to store the rope 4 along the lateral tube 22, and the rope 4 is not deformed and knotted, so that it is convenient to use and can beautify the appearance of the bicycle. Therefore, it is indeed possible to achieve the purpose of this novel.

However, the above description is only a preferred embodiment of the present invention, and the scope of the present invention cannot be limited thereto, that is, the simple equivalent change and modification made by the novel patent application scope and the novel description content, All remain within the scope of this new patent.
