Abstract

The present invention provides a transforming bicycle TT bar for reducing air resistance and weight, wherein a base bar transforms by using a bearing to reduce air resistance and weight, unlike a conventional technique where a base bar and a TT bar are separated. The transforming bicycle TT bar for reducing air resistance and weight comprises: the bearing to move the base bar to the position of the TT bar; a pair or two pairs of coupling units to connect a handle and a main body through the bearing; an elbow support to support an elbow if the handle is held by a hand when the handle is moved to the TT bar position; and a saw-toothed wheel to move the left and right sides of the coupling units where a saw-toothed wheel is present in the same position even if different forces are applied in a transforming process. The handle performs two types of functions of the base bar and the TT bar to eliminate a portion receiving air resistance. Therefore, air resistance is reduced, and weight can be reduced since a single handle can perform the role of two handles. The left and right sides can be moved to the same position even if different forces are applied in a transforming process by the saw-toothed wheel.

Description

공기저항과 무게를 줄여주는 변신하는 자전거 TT바{Transforming Time Trial Bar}A transforming bicycle TT bar that reduces air resistance and weight{Transforming Time Trial Bar}

본 발명은 자전거 tt바에 관한 것으로, 더욱 상세하게는 자전거 tt바의 베이스바를 tt바로 변신시켜, 베이스바와 tt바 총 2개의 핸들이 장착된 기존 tt바보다 상대적으로 공기저항과 무게를 줄이기 위한 공기저항과 무게를 줄여주는 변신하는 자전거 TT바에 관한 것이다. The present invention relates to a bicycle tt bar, and more particularly, by transforming the base bar of a bicycle tt bar into a tt bar, the air resistance to reduce air resistance and weight relatively than the conventional tt bar equipped with two handles, a base bar and a tt bar It is about a transforming bicycle TT bar that reduces weight and weight.

종래기술에는 장시간의 자전거경주대회에서 초반에는 선수들이 속도를 붙이기 위해 베이스바를 사용하지만, 속도가 붙으면 공기저항을 최소한으로 받으면서 In the prior art, athletes use the base bar to increase speed at the beginning of long-running bicycle races, but when the speed increases, the air resistance is received to a minimum.

장시간동안 경주를 하기 위해 베이스바는 더 이상 쓰지 않고 가운데의 tt바를 사용함으로써 경주의 대부분에서 초반과 극후반 빼고는 사용되지 않는 베이스바로 인해 쓸떼없이 공기저항만 더 만들어지고, 무게도 많이 나간다는 문제점이 있다.In order to race for a long time, the base bar is no longer used and the tt bar in the middle is used, so in most of the races, the base bar that is not used except for the beginning and the end of the race has the problem that only air resistance is created and the weight is increased. have.

따라서, 본 발명은 전술한 종래의 제반 문제점을 해결하기 위하여 안출된 것으로, 이러한 본 발명의 목적은 공기저항을 받는 면적이 줄어들어 공기저항을 줄이고, 종래보다 무게를 더 줄이도록 한 공기저항과 무게를 줄여주는 변신하는 자전거 TT바를 제공함에 있다.Accordingly, the present invention has been conceived to solve the above-described problems in the related art, and an object of the present invention is to reduce air resistance by reducing the area receiving air resistance, and to reduce air resistance and weight by reducing the weight further It is to provide the TT bar that transforms the bicycle to reduce.

본 발명은 베이스바와 tt바 두가지로 나누어지는 기존 기술과 다르게The present invention is different from the existing technology divided into two types of base bar and tt bar.

베이스바가 베어링을 이용해 tt바로 변신하여 공기저항을 줄이고,The base bar is transformed into a tt bar using bearings to reduce air resistance,

무게 감량을 한 tt바;Tt bar with weight loss;

베이스바를 상기 tt바의 위치로 이동하도록 해주는 상기 베어링 및;The bearing for moving the base bar to the position of the tt bar;

상기 베어링을 통해 손잡이와 본체를 연결해주는 1쌍 혹은 2쌍의 결합부와, One or two pairs of coupling portions that connect the handle and the body through the bearing,

상기 손잡이를 상기 tt바 위치로 이동했을 때 손으로 잡을 시 팔꿈치를 받쳐주는 팔꿈치 받침대 및;An elbow support for supporting an elbow when the handle is moved to the position of the tt bar;

변신하는 과정에서 톱니바퀴가 있는 결합부에 왼쪽, 오른쪽 각각 다른 힘을 가해도 둘 다 똑같은 위치로 이동하게 해주는 톱니바퀴를 포함하여 구성된다.In the process of transformation, even if a different force is applied to the coupling part with the toothed wheel, the left and the right side each contain a toothed wheel that allows them to move to the same position.

상술한 바와 같이 본 발명에 따른 공기저항과 무게를 줄여주는 As described above, reducing air resistance and weight according to the present invention

변신하는 자전거 TT바에 의하면,According to the transforming bicycle TT bar,

기존에 거의 사용되지 않는 베이스바를 tt바로 변신시키므로써 기존에 베이스바와 tt바를 둘다 가지고 있는 형식의 tt바보다 훨씬 더 공기저항이 줄어든다.By transforming the existing base bar, which is rarely used, into a tt bar, the air resistance is reduced much more than the existing tt bar, which has both a base bar and a tt bar.

또한 기존 베이스바와 tt바 총 2개가 달려있는 tt바보다 베이스바가 tt바로 변신함으로써,In addition, the base bar is transformed into a tt bar rather than a tt bar that has a total of two base bars and tt bars

기존에 있던 tt바를 없애기 때문에 무게를 훨씬 줄여 경량화가 가능하다.Since the existing tt bar is eliminated, the weight is much reduced and lighter weight is possible.

또한 변신하는 과정에서 결합부에 톱니바퀴가 달려있어,Also, in the process of transformation, gears are attached to the coupling part,

왼쪽, 오른쪽 각각 다른 힘을 가해도 톱니바퀴로 인해 둘 다 똑같은 위치로 이동하게 된다.Even if different forces are applied to the left and right, both move to the same position due to the cogwheel.
