Conventional pedometer for the elderly is presented as a structure that can be held and rested in a walking posture, which is inconvenient for the elderly.
Elderly people with uncomfortable walking require a walking aids with additional functions, such as being able to sit back and sometimes to load things, beyond simple functions to assist walking. Applicant research has shown that elderly people, particularly in agriculture, prefer walking aids with greater loads than those that provide chairs as needed.
Existing conventional pedestrian devices do not satisfy the needs of such consumers.
People in farming and fishing villages are increasingly aging, and they have musculoskeletal disorders and have discomfort in legs and knees. Also, considering the labor-intensive rural and rural environment, it is becoming more important to secure mobility through walking and to move products.
SUMMARY OF THE INVENTION The present invention has been made in view of the above problems, and it is an object of the present invention to provide a walking aiding device having a general versatility by allowing an appropriate loading space to be secured in addition to existing walking assistance functions to increase the transportability of objects and to implement various additional functions. In addition, it provides a cart that can greatly enhance the safety of the user in terms of functions that assist the elderly with uncomfortable walking.
Other objects and advantages of the present invention will become apparent to those skilled in the art from the following detailed description.

A cart according to an exemplary embodiment of the present invention includes a frame portion, rolling wheels, a wheel lock portion, and a stop portion. The frame part forms a plurality of frames to form an exoskeleton. The rolling wheels are connected to the lower portion of the frame. The wheel lock portion includes a grip portion connected to the frame portion, and when the grip portion is pressed downward, the wheel is unlocked so that the rolling wheels can rotate. The stop includes a brake handle connected to the frame portion and restrains rotation of the rolling wheels when the brake handle is pulled upward.
Preferably, the brake handle may be disposed below the grip portion.
Further, the grip portion is elastically lifted toward the upper portion, and when pressed, can be formed horizontally on the ground.
For example, the grip portion includes a first grip portion corresponding to the left hand and a second grip portion corresponding to the right hand, and the brake handle includes a first brake handle corresponding to the left hand and a second brake corresponding to the right hand, Handles.
Further, the grip portion may further include a grip portion connecting bar connecting the first grip portion and the second grip portion, and the brake handle further includes a brake connection bar connecting the first brake handle and the second brake handle can do.
