FIELD OF THE INVENTION

The present invention relates to a unique multi-adjustable, rotating, and opposite-double-locking umbrella-stanchion system having opposite L-shaped locking arms, which can be operated with one finger for oppositely double-locking and oppositely double-unlocking the umbrella-supporting post of a crank-arm-operated collapsible-canopy umbrella system after the umbrella supporting post is rotated to a desired position.

DESCRIPTION OF THE PRIOR ART

1) To unlock an umbrella post, rotate it to a desired position, and lock it in place, a user has to use both his hand and his foot, simultaneously.

2) While unlocking an umbrella post, rotating it to a desired position, and locking it in place, a user must stand on only one foot.

3) In order to work with the prior-art umbrella stand, the umbrella post must have a specific diameter. This require a specific umbrella post for a specific umbrella stand. As a result of this, their production cost will be higher and they require larger space in ware house.
4) In order to work with the prior-art umbrella stand, the umbrella post must have a specific diameter. This require a specific umbrella post for a specific umbrella stand. This increases inconvenience for end users.
5) The umbrella-post-locking systems of the prior art do not oppositely double-lock the umbrella post. They only single-lock the umbrella post. As a result of this, over an extended period of use, the umbrella-post-locking systems of the prior art will bend out of shape, making it harder to operate and decreasing their reliability.
6) To operate the umbrella-post-locking systems, a user must stand on one of his feet, and use the other foot and one of his hands, simultaneously. As a result of this, the umbrella-post-locking systems of the prior art are cumbersome to operate.
7) To operate the stand, a user must stand on one of his feet, and has to:a) Push down and hold the footstep (with his other foot) to unlock the umbrella post.b) Rotate the umbrella post (with his hand) to a desired position,c) Release the footstep to lift it up,d) Wiggle the footstep and the umbrella post backand forth until the locking gear of the footsteplocks between the teeth of the rotor of the umbrella, post and, thus, locks the umbrella post in place.
8) The outward-protruding foot lever of the prior-art umbrella stand poses highly hazardous risk for serious personal injuries.

OBJECTS AND ADVANTAGES OF THE INVENTION

The unique multi-adjustable, rotating, and opposite-double-locking umbrella-stanchion system overcomes all the disadvantages of the prior art heretofore. The unique multi-adjustable, rotating, and opposite-double-locking umbrella-stanchion system substantially departs from the conventional concepts and designs of the prior art. In doing so, the unique multi-adjustable, rotating, and opposite-double-locking umbrella-stanchion system provides many unique, significant advantages, some of which are, as follows:

1) It is an object of the present invention to provide a unique multi-adjustable, rotating, and opposite-double-locking umbrella-stanchion system, which can be operated with one finger. As a result, this invention eliminates the prior-art problem of requiring a user to use both hand and foot, simultaneously, to operate.
2) It is another object of the present invention to provide, a unique multi-adjustable, rotating, and opposite-double-locking umbrella-stanchion system, which allows a user to keep both feet firmly on the ground while operating the system, especially when the ground is snowy or wet. As a result, this invention eliminates personal injuries, caused by the prior art.
3) It is another object of the present invention to provide a unique multi-adjustable, rotating, and opposite-double-locking umbrella-stanchion system, which eliminates a foot pedal protruding outward from the base of an umbrella, as needed in the prior art to operate its umbrella system. A foot pedal protruding from an umbrella base is very hazardous, for example, when there are a gathering with a lot of people and young children playing and running around. They can trip on the protruding foot pedal and fall. As a result, this invention eliminates personal injuries, caused by the prior art.
4) It is another object of the present invention to provide a unique multi-adjustable, rotating, and opposite-double-locking umbrella-stanchion system, which allows a user to keep both feet firmly on the ground while operating the system. As a result, this invention allows a user to rotate the system a substantially larger angle than the prior an can.
5) It is another object of the present invention to provide a unique multi-adjustable, rotating, and opposite-double-locking umbrella-stanchion system, which oppositely double-locks the umbrella post. As a result of this, the unique multi-adjustable, rotating, and opposite-double-locking umbrella-stanchion system will not bend out of shape, over an extended period of use. This increases its reliability.
6) It is another object of the present invention to provide a unique multi-adjustable, rotating, and opposite-double-locking umbrella-stanchion system, which can be operated with one finger. As a result, this eliminates the needs for using both hand and foot, simultaneously, to operate the system, a user must stand on one of his feet, and use the other foot and one of his hands, simultaneously. Therefore, the unique multi adjustable, rotating, and opposite-double-locking umbrella-stanchion system is simple to operate.
7) It is another object of the present invention to provide a unique multi-adjustable, rotating, and opposite-double-locking umbrella-stanchion system, which can be operated with one of his fingers, as follows:a) A user simply lifts a lever on the umbrella post (with one of his fingers), andb) Simply rotates the umbrella post to a desired position, and releases the lever.
8) It is another object of the present invention to provide a unique multi-adjustable, rotating, and opposite-double-locking umbrella-stanchion system, which eliminates all hazardous levers, poking outward from the umbrella stand, keeping the umbrella stand smooth and stylish, and providing safety to user.

As a result, the unique multi-adjustable, rotating, and opposite-double-locking umbrella-stanchion system overcomes all the disadvantages of the prior art. These above and additional advantages are described and illustrated in the following examples and illustrations.

SUMMARY OF THE INVENTION

The unique multi-adjustable, rotating, and opposite-double-locking umbrella-stanchion system comprises a collapsible umbrella-canopy system, an umbrella-supporting post, a stanchion base, a U-shaped rotational lever, an actuator arm, a push rod, two opposite L-shaped locking arms, two opposite locking cleats, radial teeth, and two opposite tension springs for pushing the two opposite locking cleats downward between the radial teeth, to oppositely double-lock the umbrella-supporting post and the collapsible umbrella-canopy system, in place. The umbrella-supporting post is connected to the collapsible umbrella-canopy system. The stanchion base is connected to the umbrella-supporting post. The U-shaped rotational lever is connected to the umbrella-supporting post. Inside umbrella-supporting post and the stanchion base, the U-shaped rotational lever, the actuator arm, the push rod, the two opposite L-shaped locking, arms, and the two opposite locking cleats are connected consecutively in the above-mentioned order. The radial teeth are molded to the stanchion base. To operate the unique system, lift the rotational lever with one finger to lift the locking cleats over the radial teeth to oppositely double-unlock the supporting post. Next, rotate the supporting post to a desired position. Then, release the rotational lever such that the tension springs push the locking cleats downward back between the radial teeth to oppositely double-lock the supporting post.
