Abstract

An umbrella having a staff consisting of bottom, intermediate and top sections, the intermediate section being pivotally connected to the bottom section so as to extend either parallel to and coextensively with, or at right angles to the bottom section, and the top section being pivotally connected to the intermediate section so as to extend either coaxially therefrom or at right angles thereto, a standard foldable canopy mounted at the upper end of the top staff section and extending along the top and intermediate sections when folded, the canopy being operable by a slide movable along the top and intermediate staff sections, and mechanism operable by movement of the slide to secure the respective staff sections in desired relative positions.

Claims

1. A foldable umbrella comprising:

a. a staff consisting of bottom, intermediate and top sections, b. first pivot means interconnecting said bottom anc intermediate staff sections for pivotal movement between a closely spaced, parallel, coextensive relation and a rightangled relation, c. releasable latch means operable to secure said first pivot means at a position with the associated staff sections in right-angled relation, d. second pivot means interconnecting said intermediate and top staff sections for pivotal movement between an axially aligned relation and a right-angled relation, said second pivot means being lockable in a position with the associated staff sections in right-angled relation. e. an umbrella canopy carried by said top staff section concentrically therewith and being foldable about said intermediate and top staff sections when said staff sections are disposed in axially aligned relation, said canopy being folded and extended by means including a slide movable along said intermediate and top staff sections, said slide traversing the pivotal connection of said staff sections at an intermediate position of its movement, f. first locking means operable when engaged to lock said first pivot means with said bottom and intermediate staff sections in right-angled relation, g. second locking means operable when engaged to lock said intermediate and top staff sections in axially aligned relation, said canopy slide h. means being operable by movement thereof to respectively operatively engage and disengage said first and second locking means as said canopy slide is moved in a direction to extend said canopy, and to respectively operatively engage and disengage said second and first locking means as said canopy slide is moved in a direction to fold said canopy.

2. A foldable umbrella as recited in claim 4 wherein said first locking means comprises:

a. a locking pin operable when engaged to lock said first pivot means with said bottom and intermediate staff sections in right-angled relation, b. a second slide movable on said intermediate staff section and operably connected to said locking pin, whereby said locking pin is engaged when said second slide is moved away from said first pivot means, and disengaged when said second slide is moved toward said first pivot means, and c. a spring biasing said second slide away from said first pivot means along said intermediate staff section, said canopy slide being operable to engage and move said second slide toward said first pivot means as said canopy slide is moved to fold said canopy.

3. A foldable umbrella as recited in claim 2 wherein said second locking means comprises:

a. a sleeve mounted slidably on said top staff section above said canopy slide, and b. a spring urging said sleeve downwardly along said top section to a position in which it bridges the pivotal connection between said top and intermediAte staff sections to lock them against relative pivotal movement in coaxially aligned relation, said canopy slide being operable to engage and move said sleeve upwardly along said top staff section as said canopy slide is moved to extend said canopy.

4. A foldable umbrella as recited in claim 1 wherein said second locking means comprises:

a. a sleeve mounted slidably on said top staff section above said canopy slide, and b. a spring urging said sleeve downwardly along said top section to a position in which it bridges the pivotal connection between said top and intermediate staff sections to lock them against relative pivotal movement in coaxially aligned relation, said canopy slide being operable to engage and move said sleeve upwardly along said top staff section as said canopy slide is moved to extend said canopy.
