Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
336 words
A support structure for signs and the like for seatment upon an underlying support surface comprising first tubular means having an upper and a lower end, first yoke means slidably disposed on said first tubular means adjacent the lower end thereof, a plurality of legs having the inner ends thereof mounted on said first yoke means and the outer ends thereof provided for seatment upon the underlying support surface, second tubular means telescopically disposed within said first tubular means and having an upper and a lower end, second yoke means mounted on said second tubular means adjacent the upper end thereof, said second yoke means provided with first engagement means for engaging one edge of a sign mounted on said structure, said second yoke means being movably responsive to the movement of said second tubular means, third yoke means slidably disposed on said first tubular means above said first yoke means and including holding means for maintaining said third yoke means in any desired position along the length of said first tubular means, said third yoke means provided with second sign engagement means for engaging the opposite edge of a sign supported on said structure, and fourth yoke means slidably disposed on said second tubular means intermediate said second and third yoke means respectively, said fourth yoke means provided with stabilizing means for stabilizing a sign supported on said structure, whereby said first yoke means may be slid downwardly to spread said legs apart into a support position for supporting said structure upon an underlying support surface and said first and second engagement means and stabilizing means are independently movable with respect to one another in order to engage two opposing edges of a sign for supporting a sign on said structure and for adjusting the relative distance between the lower edge of the sign and the underlying support surface, and said stabilizing means is engageable with corresponding receiving means in the sign intermediate said first and second engagement means respectively for stabilizing the sign thereon.
Claim 2
Dependent Claim
336 words
A support structure for signs and the like for seatment upon an underlying support surface comprising first tubular means having an upper and a lower end, first yoke means slidably disposed on said first tubular means adjacent the lower end thereof, a plurality of legs having the inner ends thereof mounted on said first yoke means and the outer ends thereof provided for seatment upon the underlying support surface, second tubular means telescopically disposed within said first tubular means and having an upper and a lower end, second yoke means mounted on said second tubular means adjacent the upper end thereof, said second yoke means provided with first engagement means for engaging one edge of a sign mounted on said structure, said second yoke means being movably responsive to the movement of said second tubular means, third yoke means slidably disposed on said first tubular means above said first yoke means and including holding means for maintaining said third yoke means in any desired position along the length of said first tubular means, said third yoke means provided with second sign engagement means for engaging the opposite edge of a sign supported on said structure, and fourth yoke means slidably disposed on said second tubular means intermediate said second and third yoke means respectively, said fourth yoke means provided with stabilizing means for stabilizing a sign supported on said structure, whereby said first yoke means may be slid downwardly to spread said legs apart into a support position for supporting said structure upon an underlying support surface and said first and second engagement means and stabilizing means are independently movable with respect to one another in order to engage two opposing edges of a sign for supporting a sign on said structure and for adjusting the relative distance between the lower edge of the sign and the underlying support surface, and said stabilizing means is engageable with corresponding receiving means in the sign intermediate said first and second engagement means respectively for stabilizing the sign thereon.
Claim 3
Dependent Claim
73 words
The support structure as set forth in claim 1, wherein said first sign engagement means comprises slot means movably disposed with respect to said sign support means and adapted for engaging the upper edge of a sign supported on said structure and said second sign engagement means comprises slot means movably disposed with respect to said sign support means and adapted for engaging the lower edge of a sign supported on said structure.
Claim 4
Dependent Claim
51 words
The support structure as set forth in claim 1, wherein each of said legs further includes a support bar having an outer end pivotally mounted on said leg intermediate the outer and inner end thereof respectively, and an inner end mounted on said first tubular means adjacent the lower end thereof.
Claim 5
Dependent Claim
32 words
The support structure as set forth in claim 1, which further includes first stop means associated with said first yoke means thereby to limit the downward movement of said first yoke means.
Claim 6
Dependent Claim
36 words
The support structure as set forth in claim 1, which further includes stop means associated with Said second tubular means for locking said second tubular means in telescoped relation with respect to said first tubular means.
Claim 7
Dependent Claim
102 words
The support structure as set forth in claim 1, wherein said fourth yoke means comprises a collar having a diameter slightly greater than the diameter of said second tubular means and slightly smaller than the diameter of said first tubular means slidably mounted on said second tubular means whereby the diameter of said collar permits sliding movement only along the length of said second tubular means, said collar including a stabilizing rib fixedly mounted thereon and extending angularly outwardly therefrom and adapted for engagement with a sign supported on said structure intermediate the engaged upper and lower edges of the sign respectively.
Claim 8
Dependent Claim
40 words
The support structure as set forth in claim 6, which further includes adjustable second stop means provided on said fourth yoke means for locking said fourth yoke means in any desired position along the length of said second tubular means.
