Abstract: A control mechanism of a full-automatic multi-folded umbrella includes a bolt, a nut and a push rod disposed on the bolt and cooperating with the bolt. The push rod is connected with the nut and the top end of the middle sleeve. The lower end of the bolt is driven by a power source in the umbrella handle to turn clockwise or counterclockwise for the nut to be moved up and down along the bolt. The power source is controlled by a button on the umbrella handle. An umbrella opening/closing transformation ratio mechanism composed of two or three pull ropes is connected with each sleeve of a middle rod set as well as an upper nest and a lower nest to fold or unfold the umbrella.

Abstract: A full automatic opening and closing straight bone umbrella includes a middle bar set and an opening and closing umbrella drive mechanism in the middle bar set, an umbrella frame, an umbrella cloth, an upper nest, a middle nest, an umbrella handle, and a power source in the umbrella handle. The opening and closing umbrella drive mechanism includes a lead screw connected to the power source and an ejector sleeve driven by the lead screw. The middle bar set includes a middle pipe and an outer pipe. The ejector sleeve passes through the middle pipe and is connected to the outer pipe. When the power source is operated to drive the lead screw to turn clockwise or counterclockwise, the ejector sleeve brings the outer pipe to move up or down relative to the middle pipe to provide a full automatic opening and closing function to the umbrella.

Abstract: An opening/closing structure for an automatic umbrella contains: a shaft assembly, a frame, a notch, a first runner, a second runner, a driving mechanism, and a handle. The shaft assembly includes a first tube and a second tube. The frame couples with the notch and the second runner. The driving mechanism includes a screw rod and a push post. The push post has a drive portion and inner threads. The push post is connected with the first tube by inserting a joining element into the second tube, and the second tube has a slot longitudinally formed on an outer wall thereof. The joining element moves upwardly or downwardly along the slot. The push post has the drive portion, a coupling portion, and a deforming portion. The deforming portion is sufficiently rigid to shaft itself in an axial direction and deforms and recovers its original shape in a torque direction.

Abstract: A control device is applied to a base of an umbrella stem. A buckle sits in the base whose upper portion sets a controlling device controlled by the buckle and whose lower portion radially disposes a spool disk. The peripheral wall of the spool disk having ratchets defined thereon is embraced by a spool groove. Two ends of a spiral spring are respectively fixed to the base and the spool disk to generate an elastic force driving the spool disk's rotation. A shift block positioned under the base of the controlling device has a continuous torsion to contact the spool disk and clasp the ratchets. A disk cord provides one end fixed on the spool disk and wound around the spool groove and the other end penetrating the controlling device and the base to join an upper accommodation of the umbrella.

Abstract: A control device adapted for collapsible umbrella is applied to a base of an umbrella stem. A buckle pivots in the base whose upper portion sets a controlling device controlled by the buckle and whose lower portion radially disposes a spool disk rotated with respect to the base. The peripheral wall of the spool disk having ratchets defined thereon is embraced by a spool groove. Two ends of a spiral spring are respectively fixed to the base and the spool disk to generate an elastic force driving the spool disk's rotation. A shift block positioned under the base of the controlling device has a continuous torsion to contact the spool disk and clasp the ratchets. A disk cord provides one end fixed on the spool disk and wound around the spool groove and the other end penetrating the controlling device and the base to join an upper accommodation of the umbrella.

Abstract: This present invention discloses a treadmill comprising a base, a platform, two rollers, an endless belt, and at least two assemblies, and therefore the user can adjust the location of the adjustable assembly relative to the platform for reducing impact of the platform and varying flexibility of the platform to meet the user's demanding so as to prevent sports injury during operation period.

Abstract: A windbreak and air-ventilating folding umbrella includes a frame coupling with a linkage bar. The linkage bar has one end attached to a sleeve which is movable on the frame and another suspended to allow the linkage bar having open or close movement at the suspended end. The sleeve is formed in C-shape. There is an upper panel fastened to an anchor cap of the umbrella and the suspended end of the linkage bar, and a lower panel fastened to the rib of the umbrella. The upper panel and the lower panel have respectively a portion overlapped with each other. The umbrella thus constructed can shelter rainfall and shield sunshine, and also facilitate air ventilation, thus can prevent the umbrella from overturning in the strong wind, and is adaptable for ordinary or folding umbrellas.
