Abstract

PURPOSE: A tension retaining device of a bicycle chain is provided to prevent breakaway of a chain, generation of a noise, and damage of a frame which are caused by road shocks which hit the frame while a bicycle is operated. CONSTITUTION: A tension retaining device of a bicycle chain is attached to a chain stay of a bicycle, and composed of a roller (3). The roller retains the tension of the chain by pulling the chain. The tension retaining device which adheres to the bicycle easily adjusts the position and angle of the roller, and therefore is capable of adjusting the distance and angle from the chain.

Description

Tension retainer for bicycle chains {SAVE TENSION}

The present invention is attached to the chainstay of the bike when riding a bike, or more specifically, MTB (mountain bike) and the attached roller pulls the chain to keep the tension of the chain more taut to damage the chain and chain It is designed to prevent the falling off and reduce the noise during driving.

Utility Model Registration Number: 20-02617950000 (Registration Date: 2002-01-11)

The above design is a design that can not adjust the position and angle of the roller for the motorcycle. However, the present invention is attached to the chainstay for bicycles, it is easy to adjust the position and angle of the roller.

More specifically, when using a bicycle, the chain swings up and down depending on the impact or road condition when using mountain bikes, and if the shake increases, the chain may hit the frame and damage the frame. This can be accompanied.

The solution was to install the product of the present invention between the chain connecting the driving force between the front crank and the rear wheel in Fig. 1 so that the roller pulled the chain and tightened the tension of the chain.

Due to the present design, when the bicycle is used, the chain may prevent the chain from falling off due to the impact of the road surface, noise, and damage to the frame.

1 is a diagram illustrating names of respective parts of a bicycle. The present invention is designed to keep the tension of the chain taut, characterized in that attached to the chainstay shown in FIG.

2 is an exploded view of the present invention. It is characterized by having a frame support and a roller support 2, a roller 3, a bearing or bushing 4, a bolt 5a and a nut 5b.

The frame support 1 is a component that is coupled to the chainstay, the coupling method may be a method such as a cable or bolt. This part can be a variety of ways depending on the user's convenience. Therefore, the present invention does not have a special limitation. Frame support (1) is characterized in that there is a coupling hole (1a) to be coupled with the roller support (2). This hole is threaded, and the size of the thread is the same as that of the bolt.

Roller support (2) is a part that is coupled to the frame support (1) and the roller (3) is characterized in that there is a roller coupling hole (2b) and the position change hole (2a). As can be seen in Figure 3, the position change hole (2a) is characterized by a hole extending to one side. The position and angle of the roller 3 can be adjusted using this hole.

Roller 3 is characterized in that the bearing or bushing (4) is coupled, characterized in that a thin disc is machined on both sides to prevent the chain from falling off.

The bearing or bushing 4 is not limited in its kind. Roller 3 is a part that does not interfere with the flow of the chain, so if the part to reduce the friction between the parts can be used in accordance with the user's convenience.

Bolts and nuts are also not limited to the type and size for the user's convenience.

4 is a perspective view of the present invention assembled. A feature of the present invention is characterized in that it is attachable to the chain stay and makes it possible to adjust the position and angle of the roller 3.

5 is a perspective view showing the function of position and angle adjustment. The present invention is characterized in that attached to the chainstay of the bicycle. However, the shape of the chainstay, the angle and distance to the chains are different for every bicycle. For this reason, the position and angle of the roller 3 should be adjustable, but it can work properly. Therefore, by processing the position change hole (2a) horizontally in the roller support (2) horizontally as shown in Figure 5 is a feature of the present invention is also possible to adjust the angle at the same time.

6 and 7 are photographs showing a preferred embodiment of the present invention. When the present invention is mounted, the frame support (1) is mounted on the chainstay, and then the roller support (2) is mounted at an appropriate angle and distance from the chain, and then between the roller (3) and the roller support (2). After the chain is coupled, the roller 3 and the roller support 2 are coupled with the bolts 5a.

Claims (2)

It is attached to the chainstay of the bicycle and has a roller, and the tensioner of the bicycle chain keeps the tension of the chain more tight as the roller pulls the chain. It is easy to adjust the position and angle of the roller while attaching it to the chainstay of the bicycle, and as a result, the tension maintaining device of the bicycle chain that can adjust the distance and angle with the bicycle chain
