Abstract
Abstract The handle of an umbrella telescopes on the stick in order to reduce the overall length of the stick and handle when the umbrella is collapsed to a closed condition. The embodiment discussed in the specification includes a handle having a recess axially defined therein, a stem centrally and axially extending from the bottom of the recess and sliding within the hollow stick and a flanged bottom wall extending from the bottom of the stick having a periphery corresponding to the cross section of the recess in the handle.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
214 words
In a collapsible umbrella including a handle mounted at one end of a hollow stick comprising a plurality of telescopic sections having cross sections respectively decreasing from the handle, the handle having an axial recess defined by side and bottom walls, a centering stem fixed to the bottom wall and extending axially within the lowermost stick section of the umbrella stick for guiding relative movement therebetween, a sleeve telescopically and fixedly secured about the lowermost stick section and increasing the cross section of the stick section thereat, said sleeve having a slot therealong for removably receiving a lock lever catch therein, said sleeve including an integral flange having a periphery substantially conforming to the axial recess of the handle and reciprocatable therein; limiting stop means operatively connected between said handle and said stick and sleeve flange for limiting flange movement of said flange relative to the handle recess during an extended or retracted position corresponding to respective erected or collapsed conditions of the umbrella; and a main runner slidably mounted on said stick and having catch-lever-andcatch means thereon and including a catch displacably engagable with the slot along said sleeve, said runner having a crosssection receivable in the axial recess of said handle and movable into the axial recess when the umbrella is collapsed.

Claim 3
Dependent Claim
68 words
The structure as claimed in claim 1 in which said main runner has an upper tubular projection, a second runner slIdably supported of the stick above said main runner, said second runner having a depending sleeve upon which said main runner reciprocates when the umbrella is erected, said depending sleeve of the second runner overlying the sleeve secured to the lowermost stick section when the umbrella is collapsed.
Claim 4
Dependent Claim
37 words
The structure as claimed in claim 1 in which said main runner has lateral extensions, said handle having upper, spaced axial extensions, said handle enclosing said main runner and lateral extensions thereof when the umbrella is collapsed.
Claim 5
Dependent Claim
94 words
An umbrella as defined in claim 1 wherein the limiting stop means includes a snap ring provided in the periphery of the flange, and seats on the side wall of the handle near the top thereof and near the bottom thereof for engagement by said snap ring, whereby the handle can be retained in position, when the flange is at the top of the handle, thereby keeping the handle in its fully-extended position and a position at the bottom of the handle, when the handle is in its telescoped position, relative to the stick.
