Abstract: The present invention relates to a multi-folded umbrella with two layers of covers, which includes a frame with at least three-folded ribs, an upper cover and a lower cover. The rim of the upper cover is connected at a position above the first rib or the second rib not to extend to the end rib. When the umbrella is folded and closed, the upper cover will be hidden in the umbrella, which may have an outlook with a single cover for being facilitated to be closed or received.

Abstract: The present invention relates to a strengthened structure of a wind-proof umbrella, which includes a frame being consisted of elastic main ribs and stretched ribs being connected with related joint on the main rib. An extended rod is formed under the joint to contact the stretched rib, when the umbrella is opened, for providing a downward force to offset an upward force on the main rib and obtaining strengthened wind-proof effect to prevent the main rib from being outward folded or broken.

Abstract: This invention relates to a positioning structure for opening of an umbrella, which includes a runner movably provided around a shaft of an umbrella. The runner has a positioning hole and an extended slice placed over an opening groove. An upper jointer mounted on the top end of the shaft connects with an elastic beam, which is downward extended with a slight inclined angle and is provided with a protrusion at middle portion. And as the protrusion is engaged with the positioning hole, the elastic engagement is obtained, while the runner can be stopped in secure for keeping the umbrella in stable opening state.

Abstract: This invention discloses a connecting structure of an umbrella tip, which has an axial hole for receiving a tail rib. The tip has provided with a side engaging groove and the tail rib has provided with an elastic outward extended folded slice at its end side. While the tail rib inserts into the axial hole of the tip, the folded slice being firmly engaged with the engaging groove automatically. The manufacturing and the assembling of the tip and the tail rib are easy and convenient that obtains improved effect.

Abstract: This invention relates to a connecting structure of a wheel of a golf carrier, which is provided with a receiver on a connecting link to engage with a connecting protrusion of a shaft of the wheel by using a bolt. The connection of the receiver and the connecting protrusion of the shaft of the wheel provides a strong strength to bear pressure when the golf carrier is used. The engagement by the bolt also provides a firm effective connection and prevents the wheel from being broken or released.

Abstract: An improved safety locking mechanism according to the invention is particularly suitable for use in a five or more folding collapsible umbrella. The mechanism comprises a specially designed runner in conjunction with an actuator element. A plunger and a spring are disposed under the actuator element in a through hole formed on the runner. The plunger is urged by the spring and so will project out to abut against the upper rim of the bowed resilient element when the umbrella is opened. With such arrangements, an umbrella can be effectively kept at an open state. To close the umbrella users depress the bowed resilient element to make the plunger disengaged from the runner.

Abstract: An improved automatic opening wind resistant umbrella structure made of fiberglass reinforced plastics (FRP) mainly uses an innovative connection mechanism to associate secondary umbrella stretchers with umbrella ribs and has advantages of simplified construction and reinforced combination strength. The automatic opening wind resistant FRP umbrella structure according to the invention provides excellent convenience in use.

Abstract: An innovative stretcher structure used for collapsible two-layer canopy wind resistant umbrellas primarily uses a connection block in conjunction with two staggered curved portions each formed on a main tail plate and a secondary tail plate to enhance the wind resistant strength of an umbrella. When wind blows the umbrella, a stretcher according to the invention not only supports the umbrella canopy to endure wind but also provides a restoring force to counteract the overturning force exerted on the umbrella stretcher system by wind. Thus the present invention has an enhanced wind resistant strength.

Abstract: The present invention discloses an aluminum alloy umbrella stretcher structure having light weight and improved strength of resisting being broken by strong wind. The improvement comprises providing a carbon fiber segment on the second main umbrella stretcher. In other words, the second main umbrella stretcher according to the invention is composed of an aluminum alloy segment integrated with a carbon fiber segment effectively to enhance the strength of umbrella stretchers, avoiding being broken when the umbrella canopy is reversed by strong wind.

Abstract: A simplified pulling rope system used in multiple collapsible umbrellas comprises a mounting block and a pulley arranged on the upper portion of an umbrella rod, two rollers individually disposed on two sides of an umbrella runner, and a pulling rope one end of which is connected to a bullet-shaped element and the other end extends through the aforesaid pulley, rollers and mounting block and is finally attached to the bottom of an umbrella cap. The pulling rope system according to the invention used in a fully automatic umbrella has excellent efficiency.

Abstract: The present invention relates to a collapsing mechanism of automatic fourfold collapsible umbrellas, especially to an umbrella structure in which a restoring spring is disposed in a second parallelogrammatic frame set. The restoring spring can exert enough forces to quickly retract umbrella stretchers and ribs when an umbrella is collapsed. Thus the collapsing mechanism according to the invention can rapidly and smoothly pull down a fourfold collapsible umbrella.

Abstract: A locking mechanism of a foldable golf cart includes an elastic retainer cooperated with an engagement element provided on the upper portion of the support post of a golf cart to achieve an effective coupling through a simple operation. With this arrangement, the engagement between the parts will not loosen with ease. Thus the locking mechanism according to the invention can provide convenience in use and better stability.

Abstract: An opening mechanism of quadruple collapsible umbrellas, wherein the main improvements are two independent pulling ropes governing the movement of a runner and a stretcher system as well as the motion of the tubular elements of the umbrella stick. These improvements further include a hollow plug disposed in the umbrella stick, against the upper and the lower face of which plug two individual springs are respectively seated to provide sufficient resilient forces. A locating spring and a locating pin are arranged to prevent inadvertent triggering, which may cause damages to the umbrella.

Abstract: A windproof umbrella structure includes mainly a connector being provided at a pivoted position of the main rib and the stretcher to engage with a second rib. The invented assembled frame is covered by an upper cover and a lower cover and obtains a better umbrella strength. When the upward wind occurs, the airflow can pass through the gap between the two covers for avoiding the damage of the ribs.
