본 발명은 자동차의 스티어링 컬럼(STEERING COULMN)을 운전자에 체형 및 습관에 알맞게 자유로이 틸팅(TILTING)할 수 있도록 한 자동차용 스티어링 컬럼의 틸트구조에 관한 것으로서, 특히 조향축커버파이프 전체를 브라켓트에 직고정하여 사용시 편심조임을 방지하고, 조절레버를 파이프센터(CENTER)에 위치하게 하여 충돌시 운전자의 무릎간섭을 최소화할 수 있도록 한 자동차용 스티어링 컬럼의 틸트구종에 관한 것이다.The present invention relates to a tilt structure of a steering column for a vehicle in which a steering column (STEERING COULMN) of the automobile can be freely tilted to fit the body and habits of the driver. The present invention relates to a tilt type of a steering column for a vehicle that prevents eccentric tightening during use and minimizes driver's knee interference in a collision by positioning an adjustment lever at a pipe center.

일반적으로 자동차의 틸팅은 조향축커버파이프와 일체로 용접된 디스튼스브라켓트를 장축볼트와 조절레버와 일체로 된 너트로 고정하여 운전자가 체형에 맞게 너트를 풀어 조향축커버파이프를 전,후 이동에 의해 간편용이하게 틸팅하도록 한 것은 주지의 사실이다.In general, the tilting of the car is fixed to the dispensing bracket welded integrally with the steering shaft cover pipe with the nut integral with the long shaft bolt and the control lever, so that the driver loosens the nut to fit the body and moves the steering shaft cover pipe before and after the movement. It is a well-known fact that it was made to tilt easily by this.

그러나 종래의 틸팅(TILTING)구조는 제7도 및 제8도에서와 같이 측판에 가이드장공(102)이 형성된 한쌍의 브라켓트(101)(101') 내측에 디스튼스브라켓트(104)가 용접된 조향축커버파이프(103)를 설치한 상태에서 장축볼트(106)를 끼운후 일측에서 조절레버(109)와 일체로 고정된 너트(108)를 체결고정하였다.However, in the conventional tilting structure, as shown in FIG. 7 and FIG. 8, the stew bracket 104 is welded inside the pair of brackets 101 and 101 'having the guide holes 102 formed on the side plates. After installing the long shaft bolt 106 in the state in which the shaft cover pipe 103 is installed, the nut 108 fixed integrally with the control lever 109 is fastened and fixed.

그러나 상기와 같이 한쌍의 브라켓트(101)(101') 내측에 조향축커버파이프(103)와 일체로 된 디스튼스브라켓트(104)를 접촉되는 상태로 하여 장축볼트(106)를 끼운 후 일측에서 너트(108)로 조정하게 하므로서 조절레버(109)가 일측으로 돌출되게 되어 조절레버(109)의 작동시 일측과 타측의 조임힘이 달라 편심되게 조절됨이 발생되고, 조절레버(109)의 일측돌출도 자동차의 충돌시 운전자의 무릎과의 간섭으로 부상이 크게되는 결점과 디스튼스브라켓트의 용접작업에 따른 작업능률저하 및 코스트가 상승되는 문제점 등이 야기되었다.However, after the long shaft bolt 106 is inserted into the pair of brackets 101 and 101 'with the steering shaft cover pipe 103 integrated with the steering shaft cover pipe 103, the nut on one side is inserted. The adjustment lever 109 is protruded to one side by adjusting to 108 so that the tightening force of one side and the other side is differently generated when the adjustment lever 109 is operated, and the one-side protrusion of the adjustment lever 109 is also generated. The collision with the driver's knee during the collision of the car caused a lot of injuries and the work efficiency and cost increase due to the welding work of Disttens bracket.

본 발명은 상기한 종래의 제결점 및 문제점 등을 해결하기 위하여 안출한 것으로서, 한쌍의 브라켓트 내부에 설치되는 조향축커버파이프 양측에 조절볼트를 끼우되 브라켓트와 조향축커버파이프간에는 고정블럭을 끼운상태로 외측에서 너트를 체결한 후 양측의 너트를 조향축커버파이프 센터에 위치토록 조정레버를 용접하고, 풀고 조일시 편심됨이 전혀 없게 되는 것과 자동차의 충돌시 운전자의 무릎과 간섭됨을 전혀 없도록 함과 동시에 작업성을 용이하게 하여 코스트를 다운시킬 수 있도록 한 것이 그 목적이다.The present invention has been made in order to solve the above-described conventional drawbacks and problems, the control bolt is fitted to both sides of the steering shaft cover pipe installed inside the pair of brackets, but the fixed block is inserted between the bracket and the steering shaft cover pipe. After tightening the nut on the outside of the furnace, weld the adjustment lever to position the nuts on both sides of the steering shaft cover pipe center, so that there will be no eccentricity when unwinding and tightening, and no interference with the driver's knee during the collision of the car. At the same time, the object is to make workability easier and to lower costs.

상기의 목적을 달성할 수 있는 본 발명을 첨부된 도면에 의하여 상세히 설명하면 다음과 같다.When described in detail by the accompanying drawings, the present invention that can achieve the above object is as follows.

제1도 내지 제3도에서와 같이 측판면에 틸팅될 수 있는 가이드장공(2)이 형성된 한쌍의 브라켓트(1)(1') 내측에 핀공(3a)(3b)이 대향되는 이 대향되는 상태로 천공된 조향축커버파이프(3)를 설치하되 상기 조향축커버파이프(3)와 한쌍의 브라켓트(1)(1') 사이에는 내측에 곡면(4a)을 갖고, 외측에 평면(4b)을 갖으며, 중앙에는 핀공(5)이 형성된 고정블럭(4)을 위치한 상태에서 파이프의 내주면과 밀착될 수 있는 호형머리부(7)를 갖는 고정볼트(6)를 조향축커버파이프(3)의 내측에서 끼운 후 브라켓트(1)(1')의 외측에서 너트(8)(8')를 체결하고 상기 너트(8)(8')는 하나의 조절레버(9)에 용접고정하여서 된 것이다.As shown in FIGS. 1 to 3, the opposing state in which the pin holes 3a and 3b are opposed to the inside of the pair of brackets 1 and 1 'formed with the guide holes 2 that can be tilted on the side plate surface. Install a steering shaft cover pipe 3 perforated with a curved surface 4a on the inner side and a flat surface 4b on the outer side between the steering shaft cover pipe 3 and the pair of brackets 1 and 1 '. The center of the steering shaft cover pipe (3) has a fixing bolt (6) having an arc head (7) that can be in close contact with the inner circumferential surface of the pipe in a state in which the fixed block (4) formed with a pin hole (5) After inserting from the inside, the nuts 8 and 8 'are fastened to the outside of the brackets 1 and 1', and the nuts 8 and 8 'are fixed by welding to one control lever 9.

이때 상기 고정볼트(6)는 일측이 왼나사일 경우 오른쪽은 오른나사로 채용하여 조절레버(9)의 회전조작에 의해 브라켓트(1)(1')를 내측으로 조이거나 외측으로 풀릴 수 있도록 하는 것이다.At this time, the fixing bolt (6) is to adopt the right screw to the right side when one side is the left screw to tighten the bracket (1) (1 ') to the inside or loosen to the outside by the rotation operation of the control lever (9).

이와같이 구성된 본 발명의 조립은 한쌍의 브라켓트(1)(1') 내측에 조향축커버파이프(3)를 설치하되, 조향축커버파이프(3)의 핀공(4)(4')에 고정볼트(6)의 호형머리부(7)가 조향축커버파이프 내측에서 고정된 상태를 끼운 후 상기 고정볼트(6)에 고정블럭(4)의 핀공(5)을 이용하여 끼운 다음 브라켓트(1)(1')의 가이드장공(2)을 관통하여 브라켓트 외측에서 너트(8)(8')를 체결한다.In the assembly of the present invention configured as described above, the steering shaft cover pipe 3 is installed inside the pair of brackets 1 and 1 ', and the fixing bolts are fixed to the pin holes 4 and 4' of the steering shaft cover pipe 3. 6) After the arc head 7 is fixed inside the steering shaft cover pipe, the pin head 7 is inserted into the fixing bolt 6 using the pin hole 5 of the fixing block 4, and then the bracket 1 is attached. The nut (8) (8 ') is fastened to the outside of the bracket through the guide hole (2) of').

이때 상기 고정블럭(4)의 내측 곡면(4a)은 조향축커버파이프(3)의 외주면과 접촉하는 상태이고 외측평면(4b)은 브라켓트(1)(1')측판내면과 긴밀히 접촉되는 상태로 하여 고정볼트(4)와 너트(8)(8')가 체결되어 조향축커버파이프(3)와 브라켓트(1)(1')는 수평 상태로 고정되어 있다.At this time, the inner curved surface 4a of the fixed block 4 is in contact with the outer circumferential surface of the steering shaft cover pipe 3 and the outer flat surface 4b is in intimate contact with the inner surface of the bracket 1, 1 'side plate. The fixing bolt 4 and the nuts 8 and 8 'are fastened so that the steering shaft cover pipe 3 and the bracket 1 and 1' are fixed in a horizontal state.

상기 상태에서스티어링휠을 틸팅코조할 때에는 조절레버(9)를 제4도에서와 같이 화살표 방향으로 회전시키면 조절레버(9)에 용접된 너트(8)(8')는 고정볼트(6)로부터 회전되므로 브라켓트(1)(1')와 조향축커버파이프(3)가 헐겁게 되어 전,후 자유로이 가이드장공(23)의 거리만큼 유동할 수 있는 것이다.When tilting the steering wheel in the above state, when the adjusting lever 9 is rotated in the direction of the arrow as shown in FIG. 4, the nuts 8 and 8 'welded to the adjusting lever 9 are removed from the fixing bolt 6. Since the bracket (1) (1 ') and the steering shaft cover pipe (3) is loosened, it can flow freely before and after the distance of the guide hole (23).

그리고 운전자가 원하는 위치에서 스티어링을 정지고정시키고저 할 때에는 제5도에서와 같이 조절레버(9)를 화살표방향으로 회전시키면 조절레버(9)에 고정된 너트(8)(8')와 고정볼트(6)에 의해 조여지면서 브라켓트(1)(1')가 내측으로 평행하게 오므라들면서 고정블럭(4)이 조향축커버파이프(3)를 견고히 고정완료하는 것이다.When the driver wants to stop the steering at the desired position, as shown in FIG. 5, when the adjusting lever 9 is rotated in the direction of the arrow, the nuts 8 and 8 'fixed to the adjusting lever 9 and the fixing bolt are fixed. The fixing block 4 firmly completes the steering shaft cover pipe 3 while the brackets 1 and 1 'are retracted inward while being tightened by (6).

이때 제5도는 중간위치에서 조절고정한 상태이고 제5도는 최하단에 조절고정한 상태이다.At this time, Figure 5 is a fixed state adjustment in the middle position and Figure 5 is a fixed state fixed at the bottom.

이상 설명한 바와같이 한쌍의 브라켓트 내측에 양측에 고정블럭을 설치한 상태로 조향축커버파이프 내측에서 직접 고정하므로서 작업능률이 향상될 뿐만 아니라 고정완료 후 고정블럭이 조향축커버파이프와 브라켓트 사이에서 평행을 유지시켜 양측에서 동시에 오므라지고 펴지는 작동으로 편심작동됨이 전혀 없게 됨은 물론 조절레버를 조향축커버 파이프 센터에 위치하게 하므로서 차량 충돌시 무릎과의 간섭됨이 없어 부상정도를 적게할 수 있는 매우 유용한 발명이다.As described above, work efficiency is improved by directly fixing the inside of the steering shaft cover pipe with the fixing blocks installed on both sides inside the pair of brackets, and the fixing block is parallel between the steering shaft cover pipe and the bracket after the fixing is completed. It is very useful to reduce the degree of injury because there is no interference with the knee when the vehicle collides by maintaining the control lever at the center of the steering shaft cover pipe.
