Description

차량용 렌치Car wrench
본 발명은 각 차량마다 비치되는 렌치에 관한 것으로, 더욱 상세하게는 차량에는 타이어를 교체하기 위하여 필수적으로 구비된 자키와 자키작동핸들 및 렌치에 있어서, 렌치의 일단에 자키를 작동시킬 수 있는 자키작동핸들을 구성하여 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, in a jockey and jockey operation handle and wrench, which are essentially provided to replace a tire, a jockey operation capable of operating a jockey at one end of the wrench. The present invention relates to a vehicle wrench configured to reduce the cost of components by constructing a 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, 및 타이어의 볼트를 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 bolt.
따라서, 차량에 적재하여야 할 타이어 교체장비의 수를 줄여 원가를 절감하기 위한 노력이 필수적으로 따르게 되는 것이다.Therefore, efforts to reduce the cost by reducing the number of tire replacement equipment to be loaded on the vehicle will necessarily follow.
또한, 상기 장비들을 더욱 효과적으로 사용할 수 있도록 하기 위한 개발노력이 절실하게 필요한 현실이다.In addition, the development effort to use the equipment more effectively is an urgent need.
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.
이와 같은 타이어 교체장비는 도 8에서 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.Such a tire replacement device is a jockey operation handle composed of a jockey 100 configured to move up and down by the rotation of the rotation operation member 101 in FIG. 8, and an approximately “d” shape for rotating the rotation operation member 101 ( 110 is provided, and additionally, a wrench 1 for assembling and disassembling the cap nut fixing the tire is provided.
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. Conventional jockey 100 is coupled to the engaging hole 103 of the handle fixing part 102 formed at one end of the rotary operation member 101 by inserting the ring portion 111 formed at one end of the jockey operation handle 110, Grasping the handle 112 on the other side is rotated in a predetermined direction to move the jockey 100 up and down.
상기 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 body ascends a certain height from the ground by the lifting operation of the jockey 100, the tire is separated from the vehicle body by using the prepared wrench 1 and replaced.
상기 자키(100)와, 자키(100)를 조작하기 위한 자키작동핸들(110)은 여성이나 노약자가 조작하기 힘든 구조로 구성되어 있는 것이다. 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 결합한 후, 손잡이(112)를 잡고 일정한 방향으로 회전시켜야 하는 것이다.The 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. That is, in order to replace the tire of a passenger car with a low vehicle body, the jockey 100 is seated at the bottom of the wheel, and the engaging portion formed at the rotational operation member 101 of the jockey 100 has a ring portion 111 of the jockey operation handle 110. After coupling to 103, the handle 112 is to be rotated in a constant 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. 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 상기 자키작동핸들(110)을 이용하여 자키(100)를 작동하기가 상당히 까다로웠던 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. That is, after engaging the ring portion 111 of the jockey operation handle 110 to the coupling hole 103 formed in the rotation operation member 101, while holding the handle 112 in a state in which the inclination angle of the connection angle of about 45 ° around Should occur, the phenomenon that the ring portion 111 coupled to the coupling hole 103 is frequently generated, so that the jockey 100 is operated by using the jockey operation handle 110 unless the skilled person is somewhat skilled. It was very difficult to do.
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 자키작동핸들을 이용한 자키의 승강 작동이 원활하게 이루어지도록 하여 여성운전자나 노약자도 손쉽게 타이어를 교체장착할 수 있도록 하기 위한 것이 다른 목적이다.Another object of the present invention is to allow a female driver or an elderly person to easily replace and replace a tire by allowing a jockey to move up and down using a jockey operation handle.
상기 목적을 달성하기 위한 본 발명은 자키와 함께 구비되는 렌치를 활용하여 렌치를 자키작동핸들로 겸용할 수 있도록 함으로써 상기 목적을 해결하고자 하는 것이다. 즉 렌치의 렌치핸들 말단에 자키에 형성된 회전작동부재를 작동하기 위한 자키작동관체를 결합하여 고정하도록 구성하고, 이 자키작동관체로 자키를 작동시키도록 함으로써 해결하고자 하는 것이다.The present invention for achieving the above object is to solve the above object by using a wrench provided with a jockey to enable the wrench to be used as a jockey operation handle. In other words, it is to be solved by combining and fixing the jockey operation body for operating the rotary operation member formed on the jockey to the end of the wrench handle of the wrench, and to operate the jockey with this jockey operation body.
본 발명은 상기 목적을 해결하기 위하여, 일단에 렌치헤드가 형성되고 타측에는 렌치핸들이 구비된 렌치에 있어서, 상기 렌치핸들에 결합되는 내경을 가진 연결관체부; 상기 연결관체부의 일측을 확장하여 확장된 내경을 가진 확장관체부; 상기 확장관체부 말단에 좌우 양측으로 대칭되는 형태로 소폭의 절결부를 형성하여 좌,우 절결편을 형성하고, 상기 좌,우 절결편의 중앙부를 관통하는 체결공을 형성하여서 된 작동부재 체결부로 구성된 작동관체; 상기 작동관체의 일단에 형성된 연결관체부를 렌치의 렌치 핸들에 결합하여 고정하여서 된 것이다.The present invention, in order to solve the above object, a wrench head is formed on one end and the wrench provided with a wrench handle on the other side, the connector pipe portion having an inner diameter coupled to the wrench handle; An expansion pipe part having an inner diameter extended by extending one side of the connection pipe part; Consists of the operation member fastening portion formed by forming a small cutout in the form of symmetrical to the left and right sides at the end of the expansion pipe portion to form a left and right cutout, and forming a fastening hole penetrating the center of the left and right cutout. Working body; The connecting pipe formed at one end of the working pipe is fixed to the wrench handle of the wrench.
상기 작동부재 체결부는 자키의 일단에 형성된 회전작동부재의 핸들고정부를 절결부에 삽입하고, 체결핀을 상기 절결부의 체결공에 삽입하여 고정하도록 구성한 것이다.The actuating member fastening part is configured to insert the handle fixing part of the rotary actuating member formed at one end of the jockey to the notch, and to insert and fasten the fastening pin to the fastening hole of the notch part.
상기 작동부재체결부는 육각형의 관체와 같이 다각형을 가진 관체를 이용하여 구성할 수 있다.The operation member fastening portion can be configured using a tubular body having a polygon, such as a hexagonal tube.
본 발명의 렌치는 차량에 필수적으로 구비하여야 하는 자키세트의 구성요소를 줄여 생산가를 절감할 수 있게 되고, 노약자나 여성이라도 손쉽게 차량의 타이어를 교체장착할 수 있게 되는 특징을 나타내는 것이다. 또한, 차량을 지면으로부터 들어올리기 위한 자키의 작동이 원활하게 이루어지도록 타이어의 교체장착시간을 단축할 수 있는 부가적인 효과를 얻을 수 있다.Wrench of the present invention can reduce the production cost by reducing the components of the jockey set that must be provided in the vehicle, it is characterized by the elderly or women can easily replace the tire of the vehicle easily mounted. In addition, it is possible to obtain an additional effect of reducing the replacement installation time of the tire so that the operation of the jockey for lifting the vehicle off the ground can be performed smoothly.
