摘要：The present invention relates to a cart with easy accommodation of a handle by a spring, comprising: a loading plate in which articles are loaded at the upper portion, a cut groove is vertically penetrated to be formed at the front end, the front end is opened at the lower portion so as to be horizontally penetrated to the back end, and a space part is formed to communicate with the cut groove; driving wheels provided at the lower part of the loading plate; a cover to be coupled to the lower part of the space part; a handle member accommodated in the space part so as to be moved to the front end of the loading plate, and rotated toward the cut groove so as to be exposed to the upper part of the loading plate; a stopper formed at the cut groove side in the space portion and preventing the separation of the handle member; and a spring unit comprising a fixture provided in the back of the space part, a rotation shaft provided at the fixture, and a spring wound to the rotation shaft and of which an end is connected to the handle member so as to allow the handle member to be accommodated in the space part by a rotational restoring force when an external force is removed, wherein a handle portion can be easily accommodated at the lower part of the cart.

主权项：1. A cart with easy accommodation of a handle by a spring, comprising: a loading plate (100) that is configured to load articles on an upper side thereof, and is provided with a cut groove (122) which is formed at a front end to vertically penetrate the loading plate and a space (120) which is formed on a lower side to have an opened front end, horizontally penetrates from the front end to a rear end, and is communicatively connected to the cut groove; driving wheels (200) that are provided on a lower side of the loading plate; a cover (300) that is coupled to a lower side of the space; a handle member (400) that is accommodated in the space, is moved toward the front end of the loading plate by an external force, is rotated to the cut groove, and is exposed to the upper side of the loading plate; a stopper (500) that is formed in the space so as to be close to the cut groove, and prevents the handle member from being separated; and a spring unit (600) that includes a fixation member (620) which is provided at a rear side of the space, a rotational shaft (640) which is provided at the fixation member, and a spring (660) which is wound around the rotational shaft and of which an end is connected to the handle member to allow the handle member to be accommodated in the space by a rotation restoring force when an external force is cancelled, wherein the handle member (400) includes a lower bar (420) which is connected to the spring, an intermediate bar (440) which is connected to a central portion of the lower bar at a right angle, and an upper bar (460) which extends from an end of the intermediate bar at a right angle, a first hole (422) which is formed at one end in a longitudinal direction and penetrates from the outside to the inside, and a second hole (424) which is formed in the inside so as to have a penetrating area greater than a penetrating area of the first hole are formed in the lower bar (420), and the holes are communicatively connected, and engagement members (662) having a size corresponding to the second hole are formed at an end of the spring (660), and are fixed by being inserted into one end of the lower bar.
