본 고안은 쇼핑카트의 충돌방지장치에 관한 것으로, 상세하게는 주로 대형마트와 쇼핑몰 등에서 사용되는 쇼핑카트에 전방 거리측정센서를 부착하고 사람이나 사물이 쇼핑카트와 일정거리 이내로 들어올 경우 쇼핑카트 손잡이에 설치된 진동장치가 울리게하여 충돌을 사전에 방지하는 장치에 관한 것이다.The present invention relates to a device for preventing collision of a shopping cart, and more particularly, to a shopping cart used mainly in a large shopping mall and a shopping mall, a front distance measuring sensor is attached, and when a person or an object comes within a certain distance from the shopping cart, To a device for preventing a collision in advance by causing the installed vibration device to ring.

일반적으로 쇼핑카트는 대형마트, 백화점, 쇼핑몰 등에서 고객이 쇼핑한 물건을 싣고 이동하기 위한 목적과 용도로 사용되고 있다.In general, shopping carts are used for the purpose and purpose of carrying goods that customers shop at a shopping mall, a department store, a shopping mall, and the like.

그리고, 쇼핑카트는 물건을 싣는 바스켓과 이를 이동할 수 있게 하는 바퀴가 달린 케리어, 그리고 손잡이로 구성되어 있다.The shopping cart is composed of a basket carrying goods, a carrier with a wheel for moving the basket, and a handle.

이러한 쇼핑카트는 이동시 사용자의 부주의로 인해 전방의 물건이나 특히 사람들과의 충돌이 빈번하여 각종 사고가 많이 발생하고 있어 이러한 사고에 대비하기 위한 다양한 안전장치들이 연구, 개발되고 있다.In such a shopping cart, a lot of accidents occur frequently due to frequent collisions with objects in front of the user due to carelessness of the user when moving, and various safety devices for preparing for such accidents are being researched and developed.

이하에는 쇼핑카트의 안전장치에 대한 종래의 기술들을 요약하여 살펴본다.Hereinafter, a conventional technique for safeguarding a shopping cart will be summarized.

참고문헌 1에 : 쇼핑카트 하부에 장착되는 캐스터의 브라켓에 보호커버를 결합하여 쇼핑카트 운행시 주변 물체나 사람들에 부딪히는 경우를 완화시킬 수 있도록 한 쇼핑카트의 안전 캐스터가 개시되고 있다.Reference 1 discloses a safety caster for a shopping cart in which a protective cover is attached to a bracket of a caster mounted on a lower portion of a shopping cart so as to alleviate a situation in which a person hits a surrounding object or people when the shopping cart is operated.

참고문헌 2에 : 쇼핑카트의 휠에 제동부재와 보조롤러부를 구비시켜 무빙워크에서 승강부로 안전하게 진입시킬 수 있도록 한 쇼핑카트용 바퀴가 개시되어 있다.Reference 2 discloses a wheel for a shopping cart in which a braking member and a subsidiary roller portion are provided on a wheel of a shopping cart so that the moving work can safely enter the elevating portion.

참고문헌 3 내지 참고문헌 4에 : 쇼핑카트의 핸들부에 브레이크레버를 설치하고 브레이크레버로 바퀴에 제동력을 가하여 쇼핑카트의 비탈길 주행 등에 주변 물체와 충돌하는 것을 방지하도록 한 쇼핑카트의 브레이크장치가 개시되어 있다.Reference 3 to Reference 4 disclose a braking device for a shopping cart in which a brake lever is provided at a handle portion of a shopping cart and braking force is applied to the wheel by a brake lever to prevent collision with surrounding objects such as sloping road running of the shopping cart. .

이와 같이 쇼핑카트의 사용과정에서 발생할 수 있는 여러 가지 사고를 방지할 수 있도록 다양한 안전장치가 개발되고 있으나 사용과정에 있어 사용자의 부주의가 그 근본 원인인 점을 고려 한다면 충돌의 가능성을 사전에 감지하고 이를 쇼핑카트 사용자에게 미리 알려주는 장치는 전무한 상태이다.Various safeguards have been developed to prevent various accidents that may occur during the use of the shopping cart. However, considering that the user's carelessness in the use process is the root cause, the possibility of collision is detected in advance There is no device that informs users of shopping carts in advance.

이에 본 출원인은 쇼핑카트의 전방에 물체나 사람이 가까워지는지를 감지하고, 일정 거리 안에 들어오면 쇼핑카트 손잡이 부분을 진동시켜 충돌을 사전에 알려 사용자가 주의할 수 있도록 하는 것이다.Accordingly, the present applicant senses whether an object or a person is approaching the front of the shopping cart, and when the user comes within a certain distance, the shopping cart can vibrate the grip of the shopping cart so that the user can pay attention to the collision.
