By providing at least two elongated, telescopically engaged tube members which incorporate therein a spring biased, dual locking pin structure in combination with tube aligning and centralizing zones, a unique, adjustable handle and arm assembly is achieved which is capable of being easily moved into a plurality of alternate positions and securely engaged in each position, with unwanted dislodgement or lateral wobbling or movement being completely eliminated. In the preferred embodiment, the elongated telescopically engaged tube members are constructed with cooperating enlarged diameter zones and reduced diameter zones to prevent the unwanted disengagement of the tube members. In addition a plurality of alternate operative end units can be quickly and easily mounted to said elongated handle and arm assembly, with one of said end units comprising a unique mooring clasp and book hook construction.

An easily adjustable, securely interlocked handle and arm assembly comprising: A. a first elongated tube member incorporating a. a plurality of locking zones formed along the length of said tube, with each of said zones 1. establishing an alternate position for adjusting the operative length of the handle and arm assembly, and 2. comprising a pair of post-receiving holes formed in the wall of the tube member in juxtaposed, spaced, facing, diametrically opposed relationship to each other, and b. a reduced diameter zone formed at one end of said first elongated tube member; and B. a second elongated tube member telescopically engaged with said first tube member for sliding interengagement therewith, with one end thereof maintained within said first tube member and the opposed end thereof maintained outside the first tube member, and incorporating a. at least two locking zones formed at opposed ends of said tube member, each of said locking zones comprising a pair of post-receiving holes formed in the wall of the tube member in juxtaposed, spaced, facing diametrically opposed relationship to each other, b. a reduced diameter zone formed at the end of said tube member maintained outside of the first tube member, and c. an enlarged diameter zone formed at the end of said tube member maintained within the first tube member, said enlarged diameter being greater than the reduced diameter of the first tube member, thereby preventing removal of said second tube member from said first tube member; and C. at least one spring loaded, dual-post locking member a. mounted within said second elongated tube in cooperating interengagement with one of said pairs of post-receiving holes, and b. maintained with said post members thereof biased into locked interengagement with said post receiving holes, ready for locked interengagement with any pair of post receiving holes formed in said first elongated tube member, whereby said second elongated tube member can be quickly and easily moved into interlocked engagement with said first elongated tube member in any one of a plurality of locking zones formed along the length thereof, thereby providing a handle and arm assembly which can be quickly and easily adjusted to have its operative length changed to any particular desired configuration, while also preventing accidental removal of said second elongated tube member from said first elongated tube member.
