Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
183 words
A movable barrier adapted for positioning in blocking or accessible relation to a predetermined area, said barrier comprising at least one elongated upright, a socket secured to the ground and formed with means for pivotally mounting one end of said upright for movement of said upright between a first substantially horizontal and a second substantially vertical position, a cross-bar fixed to an end of said elongated upright opposite said one end and extending laterally therefrom, an adjustable length stay operatively mounted at one of its ends, to said cross bar for pivotal movement relative thereto in laterally spaced relation to said opposite end of said upright, the opposite end of said stay being laterally spaced from and in offset relation to said one end of said upright and being mounted by means separate from said socket for pivotal movement relative to the ground, said stay, in said first position of said upright, lying in a substantially horizontal plane together with said upright and said cross-bar and, in said second position of said upright, being obliquely related to said upright and to said cross-bar.
Claim 2
Dependent Claim
183 words
A movable barrier adapted for positioning in blocking or accessible relation to a predetermined area, said barrier comprising at least one elongated upright, a socket secured to the ground and formed with means for pivotally mounting one end of said upright for movement of said upright between a first substantially horizontal and a second substantially vertical position, a cross-bar fixed to an end of said elongated upright opposite said one end and extending laterally therefrom, an adjustable length stay operatively mounted at one of its ends, to said cross bar for pivotal movement relative thereto in laterally spaced relation to said opposite end of said upright, the opposite end of said stay being laterally spaced from and in offset relation to said one end of said upright and being mounted by means separate from said socket for pivotal movement relative to the ground, said stay, in said first position of said upright, lying in a substantially horizontal plane together with said upright and said cross-bar and, in said second position of said upright, being obliquely related to said upright and to said cross-bar.
Claim 3
Dependent Claim
33 words
A device according to claim 1, wherein said adjustable length stay comprises telescopically related parts, and means for locking said telescopically related parts together when said upright is in said second position thereof.
Claim 4
Dependent Claim
28 words
A device according to claim 2, wherein said means for locking said parts together comprise a safety lock having a removable barrel acting as an extractable locking pin.
Claim 5
Dependent Claim
61 words
A device according to claim 1, wherein a second upright is provided which is also pivotally mounted at one of its ends and forming with said first-named upright and said cross-bar an archlike structure, said one end of said stay being mounted for pivotal movement relative to said cross-bar by a sleeve carried by the cross-bar for rotary movement relative thereto.
