Description

CLAIM OF PRIORITY

This application claims the benefit of priority to U.S. Provisional Patent Application No. 62/710,991, filed Mar. 6, 2018, the disclosure of which is fully incorporated herein by reference.

FIELD OF THE INVENTION

The present invention relates generally to an extendable umbrella. More particularly, the present invention relates to an extendable umbrella having a shaft, where the outside of the shaft serves as a guide for an umbrella runner which allows for the opening and closing of a canopy and the inside of the shaft contains multiple lockable adjustable height telescoping tubes that can be extended from the shaft and all the way to the ground if desired to provide support to the umbrella while it is being held by a person in a standing position.

BACKGROUND OF THE INVENTION

According to Wikipedia, an umbrella (or parasol) is a folding canopy supported by wooden or metal ribs, which is usually mounted on a wooden, metal or plastic pole that may instead be referred to as a tube or shaft. Umbrellas and parasols are primarily hand-held portable devices sized for personal use. The largest hand-portable umbrellas are golf umbrellas. Umbrellas can be divided into two categories: fully collapsible umbrellas, in which the metal pole supporting the canopy retracts, making the umbrella small enough to fit in a handbag; and non-collapsible umbrellas, in which the support pole cannot retract and only the canopy can be collapsed. Another distinction can be made between manually operated umbrellas and spring-loaded automatic umbrellas which spring open at the press of a button.

FIG. 1 (PRIORT ART) depicts a cross-sectional view of an exemplary prior art umbrella 100 (see Richtom80 at the English language Wikipedia, CC BY-SA 3.0). Referring to FIG. 1 (PRIOR ART), the umbrella 100 includes a shaft 102 within which a top spring 104 and bottom spring 106 are configured such that, when the bottom spring 106 is depressed, the umbrella's runner 108 can be moved from a closed position beneath the bottom spring 106 to an open position above the top spring 104 where it will be maintained in the open position by the top spring 104 and, when the top spring 104 is depressed, the umbrella's runner 108 can be moved from the open position to the closed position where it will be maintained in the closed position by the bottom spring 106. Near the top of the shaft 102 are a top notch 110, open cap 112, end 114, and ferrule 116. Ribs 118a and 118b to which a canopy (not shown) is attached are each held in place at one end between the top notch 110 and the open cap 112. Stretchers 120a and 120b are attached to ribs 118a and 118b and to the runner 108. When the runner 108 is moved to the open position the ribs 118a and 118b are extended outward and when the runner 108 is moved to the closed position the ribs 118a and 118b are moved inwards towards the shaft 102. The end 114 of the umbrella has the ferrule 116 for strengthening the end 114 of the tube to prevent it from splitting or wearing. At the bottom of the shaft 102 is a tip cup 122 and a crook handle 124. Also shown in FIG. 1 (PRIOR ART) is an optional center ball spring 126 that can be found on telescopic collapsible umbrellas, which is not present (or necessary) on non-collapsible umbrellas. Non-collapsible umbrellas such as golf umbrellas may or may not have a bottom spring 106 and typically have a rubber handle grip that is straight (i.e., without a crook).

Various types of extendable adjustable height poles are well known for use as walking poles or camera support poles. Such extendable adjustable height poles typically have several nested telescoping tubes, which may be made of aluminum or plastic, and locking mechanisms associated with each telescoping tube enabling the pole to be collapsed to a minimum height (e.g., 16″) and extended up to a maximum height (e.g., 59″). Various types of locking mechanisms are commonly used with such poles such as flip-lever clamps, compression rings, button clips and the like.

FIGS. 2A-2C (PRIOR ART) depict an exemplary extendable adjustable height pole 200 called the Element 59″ Monopod, which is sold by Manfrotto. In FIG. 2A (PRIOR ART), the pole 200 is shown fully extended. The pole 200 includes a main shaft 202 having a handle 204 and a strap 206. Four telescoping tubes 208a, 208b, 208c, 208d are shown fully extended and locked in position using compression rings 210a, 210b, 210c, 210d. At the bottom of the pole 200 is a rubber foot 212 and on top of the pole is a top cap 214. In FIG. 2B (PRIOR ART), the pole 200 is shown fully collapsed. FIG. 2C (PRIOR ART) depicts an enlarged image of the shaft 202, telescoping tubes 208a, 208b, 208c, 208d, compression rings 210a, 210b, 210c, 210d and rubber foot 212.

FIG. 2D (PRIOR ART) depicts another exemplary extendable adjustable height pole 200 called the Tg-tpm67-101 67″ Monopod, which is sold by Targus. In FIG. 2D (PRIOR ART), the pole 200 is shown fully collapsed. The pole 200 includes a main shaft 202 having a handle 204 and a strap 206. Three telescoping tubes 208a, 208b, 208c are shown partially collapsed and locked in position using flip-lever clamps 216a, 216b, 216c. At the bottom of the pole 200 is a rubber foot 212 and on top of the pole is a top cap 214.
