Abstract
Abstract A combination umbrella and golf ball retriever which uses the umbrella strut as a socket pipe to accommodate several telescopically nested tubes so as to form an elongated handle for a golf ball retriever. There is an eccentric-grooved stud inserted at one end of the inside tube of each two neighboring tubes. The eccentric-grooved portion of this stud matches with a similar eccentric circular bushing. When the inner tube turns to one direction, the outside part of the circular bushing will press tightly against the inner wall of the outside tube and lock up the two neighboring tubes. An opposite turn at the inner tube will set loose the circular bushing and allow both neighboring tubes to slide in and out freely so as to adjust the length of the handle of the golf ball retriever.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
176 words
A combination umbrella and golf ball retriever comprising: an umbrella having a hollow tubular member serving as a main strut thereof, said tubular member being provided with a grip at an end thereof to serve as a handle for said umbrella; a golf ball retriever formed of a plurality of telescopically nested tubular members of successively smaller diameters fitted one inside another, the smallest of said tubular members having a golf ball retriever head installed at an end thereof; said umbrella handle and said main strut serving as a socket pipe telescopically accommodating said telescopically nested tubes of said golf ball retriever therewithin so that said umbrella handle and said umbrella when in a closed condition form an elongated handle for said golf ball retriever; and releasable locking means arranged between each contiguous pair of said telescopic tubular members of the umbrella and the golf ball retriever whereby each of said members may be released to telescopically move relative to the next larger member and may be locked in a position to which it is moved.
Claim 2
Dependent Claim
176 words
A combination umbrella and golf ball retriever comprising: an umbrella having a hollow tubular member serving as a main strut thereof, said tubular member being provided with a grip at an end thereof to serve as a handle for said umbrella; a golf ball retriever formed of a plurality of telescopically nested tubular members of successively smaller diameters fitted one inside another, the smallest of said tubular members having a golf ball retriever head installed at an end thereof; said umbrella handle and said main strut serving as a socket pipe telescopically accommodating said telescopically nested tubes of said golf ball retriever therewithin so that said umbrella handle and said umbrella when in a closed condition form an elongated handle for said golf ball retriever; and releasable locking means arranged between each contiguous pair of said telescopic tubular members of the umbrella and the golf ball retriever whereby each of said members may be released to telescopically move relative to the next larger member and may be locked in a position to which it is moved.
Claim 3
Dependent Claim
116 words
A combination umbrella and golf ball retriever as recited in claim 1 wherein said releasable locking means comprises a eccentric-grooved stud inserted at one end of the inner tubular member of each contiguous pair which matches with a similar eccentric circular bushing such that rotation of said inner tubular member with respect to the outer tubular member of the pair in one direction will press an outer part of said circular bushing against an inner wall of said outer tubular member to lock said members in said position, and rotation of said inner tubular member in the opposite direction will release said bushing and allow said tubular members to slide telescopically with respect to each other.
