차량용 렌치{wrench of car}Wrench of car}

본 발명은 각 차량마다 비치되는 렌치에 관한 것으로, 더욱 상세하게는 차량의 타이어를 교체하기 위한 필수구성품목인 자키와 자키작동핸들 및 렌치가 필수적으로 구비하도록 되어 있는바, 렌치의 일단에 자키를 작동시킬 수 있는 자키작동핸들을 구성함으로써 구성품목을 줄여 원가를 절감할 수 있도록 한 차량용 렌치에 관한 것이다.The present invention relates to a wrench provided for each vehicle, and more particularly, the jockey and jockey operation handles and wrenches, which are essential components for replacing tires of the vehicle, are essentially provided, and the jockey is operated at one end of the wrench. The present invention relates to a vehicle wrench that can reduce the cost of components by constructing a jockey operation handle.

일반적으로 차량에는 타이어를 교체할 때 필요한 각종 장비가 필수적으로 비치하게 되어 있다.In general, the vehicle is essentially equipped with a variety of equipment required to replace the tire.

타이어를 교체할 때 필요한 장비로는 차량을 들어올리기 위한 자키와, 자키를 작동시키기 위한 자키작동핸들, 타이어의 보울트를 풀거나 조립하기 위한 렌치 등이 필수적으로 구비되어야 한다.Equipment required to replace the tire must be provided with a jockey for lifting the vehicle, a jockey operation handle for operating the jockey, a wrench for loosening or assembling the tire's bowl.

따라서, 차량에 적재하여야 할 상기한 타이어 교체장비의 수를 줄여 원가를 절감하기 위한 노력이 필수적으로 따르게 되는 것이다.Therefore, efforts to reduce the cost by reducing the number of the above-described tire replacement equipment to be loaded on the vehicle will necessarily follow.

또한, 상기한 장비들을 더욱 효과적으로 사용할 수 있도록 하기 위한 개발노력이 절실하게 필요한 현실이다.In addition, the development efforts to be able to use the above equipment more effectively is a reality that is urgently needed.

종래 차량에 구비되어 있는 타이어 교체장비로서 자키와 자키작동핸들 및 렌치가 하나의 세트로서 구비되어 있다.As a tire replacement device provided in a conventional vehicle, a jockey, a jockey operation handle, and a wrench are provided as a set.

상기한 타이어 교체장비는 첨부도면 도8 나타난 바와 같이, 회전작동부재(101)의 회전으로 승강작동하도록 된 자키(100)와, 상기 회전작동부재(101)를 회전시키기 위한 대략 "ㄹ"자형으로 구성된 자키작동핸들(110)이 구비되고, 부가적으로 타이어를 고정하고 있는 캡너트를 조립 및 분해하기 위한 렌치(1)가 구비된다.As shown in FIG. 8, the tire replacement device includes a jockey 100 configured to move up and down by the rotation of the rotary operation member 101, and a substantially “d” shape for rotating the rotary operation member 101. FIG. The configured jockey operation handle 110 is provided, and additionally, a wrench 1 for assembling and disassembling the cap nut fixing the tire is provided.

상기한 종래의 자키(100)는, 회전작동부재(101)의 일단에 형성된 핸들고정부(102)의 결합공(103)에 자키작동핸들(110)의 일단에 형성된 고리부(111)를 끼워 결합하고, 타측의 손잡이(112)를 잡고 일정한 방향으로 회전시켜 상기 자키(100)를 승, 하강작동하도록 된 것이다.In the conventional jockey 100, the hook portion 111 formed at one end of the jockey operation handle 110 is inserted into the coupling hole 103 of the handle fixing part 102 formed at one end of the rotation operation member 101. To combine, grab the handle 112 on the other side and rotate in a predetermined direction to move the jockey 100 up and down.

상기한 자키(100)의 승강작동으로 차체에 장착된 타이어가 지면으로부터 일정 높이 상승하게 되면, 준비된 렌치(1)를 이용하여 타이어를 차체로부터 분리하여 교환을 하게 되는 것이다.When the tire mounted on the vehicle ascends a certain height from the ground by the elevating operation of the jockey 100, the tire is separated from the vehicle body using the prepared wrench 1 to be replaced.

상기한 종래의 자키(100)와, 이 자키(100)를 조작하기 위한 자키작동핸들(110)은 여성이나 노약자가 조작하기 힘든 구조로 구성되어 있는 것이다.The conventional jockey 100 and the jockey operation handle 110 for manipulating the jockey 100 are configured in a structure that is difficult for a woman or an elderly person to operate.

즉, 차체가 낮은 승용차의 타이어를 교환하기 위해서는, 차륜 하단에 자키(100)를 안착하고, 자키작동핸들(110)의 고리부(111)를 자키(100)의 회전작동부재(101)에 형성된 결합공(103)에 결합 한 후, 손잡이(112)를 잡고 일정한 방향으 로 회전시켜야 하는 것이다.That is, in order to replace the tire of a passenger car having a low vehicle body, the jockey 100 is seated at the lower end of the wheel, and the ring portion 111 of the jockey operation handle 110 is formed on the rotation operation member 101 of the jockey 100. After coupling to the coupling hole 103, the handle 112 is to be rotated in a predetermined direction.

따라서, "ㄹ"자형으로 제작된 자키작동핸들(110)의 회전력만으로 자키(100)의 회전작동부재(101)를 회전시켜야 하는데, 좁은 공간에서 자키작동핸들(110)을 이용한 자키(100)의 작동작업은 숙련된 사람이 아니면 자키(100)의 작동이 어렵게 이루어지는 단점이 있는 것이다.Therefore, the rotation operation member 101 of the jockey 100 needs to be rotated only by the rotational force of the jockey operation handle 110 manufactured in a "d" shape, and the jockey 100 using the jockey operation handle 110 in a narrow space. Operational work is a disadvantage that the operation of the jockey 100 is difficult unless a skilled person.

즉, 회전작동부재(101)에 형성된 결합공(103)에 자키작동핸들(110)의 고리부(111)를 결합한 후, 연결각도를 45° 내외의 경사각을 이룬 상태에서 손잡이(112)를 잡고 회전시켜야 하는데, 결합공(103)에 결합된 고리부(111)이 이탈하는 현상이 빈번하게 발생하여, 어느 정도 숙련된 사람이 아니고는 상기한 자키작동핸들(110)을 이용하여 자키(100)를 작동하기가 상당히 까다로웠던 것이다.That is, after coupling the ring portion 111 of the jockey operation handle 110 to the coupling hole 103 formed in the rotary operation member 101, while holding the handle 112 in a state in which the inclination angle of about 45 ° Should be rotated, the phenomenon that the ring portion 111 coupled to the coupling hole 103 is frequently generated, the jockey 100 using the jockey operation handle 110, unless the skilled person to some extent It was quite tricky to operate.

이러한 자키(100)의 작동이 불편하게 되면 안전사고의 발생 우려까지 있는 것이다.If the operation of the jockey 100 becomes inconvenient, there is a fear of the occurrence of a safety accident.

본 발명은 상기한 문제점을 해결하기 위한 것으로, 출고되는 차량에 구비되는 타이어의 교체장비 숫자를 줄임으로써 교체장비를 저가로 제공할 수 있도록 하는 것을 목적으로 하는 것이다.The present invention is to solve the above problems, it is an object to provide a low cost replacement equipment by reducing the number of replacement equipment of the tire provided in the vehicle shipped.

본 발명의 다른 목적은, 자키작동핸들을 이용한 자키의 승강 작동이 원활하게 이루어지도록 함으로써, 여성운전자나 노약자도 손쉽게 타이어를 교체장착할 수 있도록 하는 것을 본 발명의 다른 목적으로 하는 것이다.Another object of the present invention is to make it possible to smoothly raise and lower the jockey using the jockey operation handle, so that a female driver or an elderly person can easily replace and replace the tire.

상기한 목적을 달성하기 위한 본 발명은, 자키와 함께 구비되는 렌치를 활용하여 상기 렌치를 자키작동핸들로 겸용할 수 있도록 함으로써 상기한 목적을 해결하고자 하는 것이다.The present invention for achieving the above object is to solve the above object by utilizing the wrench provided with the jockey can be used as the jockey operating handle.

즉, 렌치의 렌치핸들 말단에 자키에 형성된 회전작동부재를 작동하기 위한 자키작동관체를 결합하여 고정하도록 구성하고, 이 자키작동관체가 장착된 렌치를 이용하여 자키를 작동시키도록 함으로써 해결하고자 하는 것이다.That is, it is intended to solve by combining and fixing the jockey operation body for operating the rotary operation member formed on the jockey at the end of the wrench handle of the wrench, and to operate the jockey using a wrench equipped with the jockey operation body. .

상기한 구성으로 된 본 발명의 렌치는, 차량에 필수적으로 구비하여야 하는 자키세트의 구성요소를 줄임으로써 생산가를 절감할 수 있게 되며, 노약자나 여성이라도 손쉽게 차량의 타이어를 교체장착할 수 있게 되는 특징을 나타내는 것이다.Wrench of the present invention having the above configuration, it is possible to reduce the production cost by reducing the components of the jockey set that must be provided in the vehicle, it is easy to replace the tires of the vehicle, even the elderly and women It represents.

또한, 차량을 지면으로부터 들어올리기 위한 자키의 작동을 원활히 함으로써 타이어의 교체장착시간을 단축할 수 있는 부가적인 효과를 얻을 수 있다.In addition, it is possible to obtain an additional effect of reducing the tire replacement time by smoothly operating the jockey for lifting the vehicle off the ground.
