The present disclosure relates to a walking aid 100. The walking aid 100 includes a frame 102, two support struts 104A, 104B, and two support arms 106A, 106B. The two support struts 104A, 104B extend vertically from the frame 102, where each of the two support struts 104A, 104B is adjustable. The two support arms 106A, 106B are connected to each of the 5 two support struts 104A, 104B, where each of the two support arms 106A, 106B extends outward adjacent to each of the two support struts 104A, 104B. Therefore, the walking aid 100 ensures the comfort for a user, enabling the users to navigate confidently while maintaining stability and ease of movement.

Folding seat stick via toothed gear engagement, comprising: - a pivot bearing (10) on which three rectangular channels (11) are arranged radially distributed, wherein the enclosed angle between each two rectangular channels (11) is the same, wherein a barrier wall (111) is arranged on the outer circumference of the rectangular channel (11) which has an upper inclined edge (112) in the upper area and a lower inclined edge (113) in the lower area; - three lower support legs (20), each having at its upper end a flat round head which is pivotably connected to the lower part of the corresponding rectangular channel (11); - a first upper support arm (30), a second upper support arm (30A) and a third upper support arm (300), each having a lower flat round head at its lower end which is pivotably connected to the upper part of the corresponding rectangular channel (11), wherein the first and the second upper support arms (30, 30A) are each connected at their upper part to a support tube (32) on the upper part of which a cardan joint (321) is arranged, while the third upper support arm (300) is connected at its upper part to a main support tube (33) whose upper part is connected to an arm support (34), wherein a sliding bearing (40) is arranged on the main support tube (33) which is provided with a sliding tube (41) and a curved round part (42), wherein the sliding tube (41) is provided for guiding the main support tube (33) and the third upper support arm (300) into the sliding tube (41),wherein a locking button (43) is arranged on the outside of the sliding bearing (40), wherein by actuating the locking button (43) the sliding bearing (41) is raised or lowered along the main support tube (33) and then fixed to the main support tube (33); and , - a seat surface (50) consisting of a main surface (51) and two side surfaces (52) pivotably connected to one another, wherein the curved round part (42) of the sliding bearing (40) is pivotably connected to the lower part of the main surface (51), wherein the cardan joints (321) of the support tubes (32) are pivotably connected to the lower sides of the side surfaces (52), characterized in that an upper gear unit (21) is arranged around the upper flat round head of the respective lower support leg (20) and a lower gear unit (31) is arranged around the lower flat round head of the first, second and third upper support arms (30, 30A, 300), wherein the upper gear units (21) of the lower support legs (20) and the lower gear units (31) of the first, second and third upper support arms (30, 30A, 300) mesh accordingly with one another intervenewherein the inner surfaces of the main surface (51) are synchronously raised or lowered by raising or lowering the sliding bearing (40), thereby moving the two side surfaces (52) so that they are folded down laterally or unfolded upwards, which in turn causes the first, second and third upper support arms (30, 30A, 300) to move and thus be folded or unfolded, wherein the lower gear units (31) drive the upper gear units (21) so that the lower three support legs (20) are folded or unfolded relative to each other.

This is a device with two pivotable legs (5) and an extension lever (3), that makes a walking aid such as crutches or similar items stand upright independently. The deployed legs (5) and the walking aid form a stable tripod. The legs (5), which are resting in a space-saving upward position parallel to the main tube (2), are deployed by lifting the walking aid and by pulling a lever (3), which is connected with a string (C) to the legs (5). The legs (5) make a forward rotation until blocked by a blocker (10), while gravity keeps them blocked and the walking aid standing once put on the ground. The legs (5) return automatically to their resting position through the pulling force of a spring by lifting the walking aid. The leg's (5) tips relative position from space-saving to tripod changes during the rotation through two incorporated angles.

In one embodiment, a kinetic shape is designed by determining an applied force to be applied to an object that is to incorporate the kinetic shape, determining a reactive force that is desired to be produced in response to the applied force, inputting the applied force and the reactive force into a kinetic shape equation, and solving the equation to obtain the kinetic shape.
