Abstract: An end unit mounted to an umbrella ferrule includes a tube, a ball and a pad. The tube has a top collar connected to the top thereof and a bottom member is received in the tube. A room is defined between the bottom member and the lower end of the tube. The ball is pivotably engaged with the room and the top of the ball contacts the bottom member. The ball has a shank which is connected to the pad. The bottom member provides proper friction to allow the ball to pivot.

Abstract: This invention discloses a walking stick including a main body, a pivot connector and a socket. The main body is of the shape of stick and connects to the socket through the pivot connector. A sphere is inside the pivot connector. A sliding-proof elastic element locates between the bottom of the main body and the sphere. The sliding-proof elastic element and the sphere are mounted inside the pivot connector. A bottom of the sphere reaches the socket through the pivot connector. The sphere rotates inside the pivot connector as the socket moves, while being urged against the sliding-proof elastic element. The sliding-proof elastic element has characteristics of sliding proof, elasticity and wear resistance. Thereby the walking stick of the invention offers all-round support for the user in use. Especially the sliding proof effect of the sliding-proof elastic element restrains the instant movement of the sphere, and its elasticity offers an effect of shock resistance.

Abstract: A structural improvement for a foldaway bicycle includes a head tube having a handlebar on the top and a front wheel at the bottom, a two-piece slant cross bar having a front end pivoted to a positioning device on the head tube, and a rear end respectively connected to a rear wheel and a pair of extensions each of which has a standing roller, a slant down tube having a lower end pivoted to a lug on the head tube and a turning point in a middle portion pivoted to a lug of the cross bar, a driving set having a belt wheel carrying a belt and a crank with pedals pivoted to an inverse U-shaped seat on an underside of the cross bar and a seat tube having an upper periphery connected to the upper end of the down tube, an adjustable saddle with a pulling handle on the top and an elastic pad at a lower end stopped against the top of the inverse U-shaped seat.

Abstract: A shock-absorbing device includes a first crank member, a buffering unit and a second crank member. The first crank member has a first hole formed therein. The buffering unit is inserted into the first hole, and has a cylindrical hollow outer wall, a cylindrical hollow inner wall coaxially mounted in the outer wall, an annular rubber cushion disposed between the inner and outer walls, and a shaft extending through and engaging the inner wall. The outer wall engaging the first crank member. The second crank member is connected to and is rotatable about and together with the shaft. The rubber cushion is deformed by the outer and inner walls in order to retard pivotal movement of the first crank member relative to the second crank member about the shaft.
