ABSTRACT:
FIELD OF THE INVENTION
This invention relates to a novel combination umbrella and picnic cooler or carrier vessel.
BACKGROUND OF THE INVENTION
Telescopically collapsible umbrellas have been in use before in this art. In the ordinary umbrella, such as is well known in the art, the usual light folding flexible frame of spring steel ribs is disposed in “spoke-like” arrangement to form a supporting frame which is usually covered with a rain and sun resisting fabric or other flexible material suitably fastened thereto. A slotted ferrule slides up and down the mast and carries ribs which are pivotally connected to the fabric supporting ribs, as well as to the ferrule. Spring latch means protrude, and are urged outwardly, from the mast at suitable places. One latch is located near the upper end of the mast, over which the ferrule passes, and engages the under side of the ferrule to maintain the umbrella in open or raised position. Another spring latch is located toward the lower end of the mast, adapted to protrude through the slot of the ferrule and maintain the umbrella in closed or collapsed position.
SUMMARY OF THE INVENTION
In the present invention, a novel means is provided to maintain the light flexible umbrella frame and fabric cover in juxtaposed stand-off and uniformly spaced apart position with relation to the main mast of the umbrella. This most important feature is required to permit the umbrella frame and cover to enfold and surround the vessel gracefully and compactly.
The principal object of this invention is to provide a novel cooler or carrier vessel which is combined in one unit with an umbrella of novel design, the supporting mast of the umbrella being adapted to telescope within the vessel when the umbrella is closed in a manner whereby the fabric of the umbrella surrounds and envelops a portion of the vessel.
Another object of the present invention is to provide a unitary combination umbrella and cooler or carrier vessel which is easy to open and close, and presents an attractive appearance in either open or closed position.
A further object is to provide, in a combined umbrella and vessel, a novel arrangement of operating elements which is of low cost to manufacture, has a minimum of working parts and which is easy to assemble, durable and requires little maintenance in use.
A still further object is to provide a novel combined unitary umbrella and vessel which is semi-automatic in opening and closing action.
Still another object is to provide, in a dual purpose umbrella and picnic cooler, novel means to maintain the ribs of the light flexible frame and covering fabric in an even juxtaposed stand-off position with relation to the central telescopic supporting mast of the umbrella when it is collapsed so that it may envelop and surround the vessel in an attractive manner and which provides a shorter mast and more compact structure over all.
Another object is to provide spring actuated, easily operated, manually releasable, snap locking means in a combination telescoping umbrella and vessel, which maintains the umbrella in both positive open raised position above the vessel, or in positive collapsed position, with the frame and fabric evenly surrounding the vessel.
Another object is to provide a modified form of combined umbrella and vessel comprising a novel and useful arrangement of parts, whereby the entire umbrella, including its supporting frame and cover fabric, may be telescoped and collapsed when lowered and closed and folded completely within a central container disposed within the vessel, in a compact manner providing a large remaining space within the vessel for receiving objects to be carried
Further objects and advantages of this invention will be apparent from the following detailed description of a presently preferred embodiment, shown schematically in the accompanying drawings.
