Claims Analysis

Total Claims: 9
Claim 1
Independent Claim 147 words
A retractable stand for trailer tongues, said stand comprising a mounting plate adapted to be fastened to a trailer tongue, a pivot pin attached to said mounting plate and defining a pivotal axis, an elongated support member with longitudinal peripheral surfaces and a longitudinal slot near one end, said slot cooperating with said pivot pin, said support member being movable selectively between first and second angular positions about said pivot pin, and a pair of spaced stop members affixed to said mounting plate and spaced apart from each other to defIne a keyway of sufficient dimension to snugly receive said support member therebetween when in said first position, and said stop members each further snugly engaging the longitudinal peripheral surfaces of a common side of said support member when said support member is in said second position, thus preventing movement when in said first and second positions.
Claim 2
Dependent Claim 147 words
A retractable stand for trailer tongues, said stand comprising a mounting plate adapted to be fastened to a trailer tongue, a pivot pin attached to said mounting plate and defining a pivotal axis, an elongated support member with longitudinal peripheral surfaces and a longitudinal slot near one end, said slot cooperating with said pivot pin, said support member being movable selectively between first and second angular positions about said pivot pin, and a pair of spaced stop members affixed to said mounting plate and spaced apart from each other to defIne a keyway of sufficient dimension to snugly receive said support member therebetween when in said first position, and said stop members each further snugly engaging the longitudinal peripheral surfaces of a common side of said support member when said support member is in said second position, thus preventing movement when in said first and second positions.
Claim 3
Dependent Claim 20 words
The stand set forth in claim 1 wherein said first and second angular positions are generally perpendicular to each other.
Claim 4
Dependent Claim 22 words
The stand set forth in claim 1 together with means biasing said peripheral surfaces of said support member toward said stop members.
Claim 5
Dependent Claim 23 words
The stand set forth in claim 3 wherein said biasing means includes a spring extending between said mounting member and said support member.
Claim 6
Dependent Claim 17 words
The stand set forth in claim 4 wherein said spring is comprised of a coil tension spring.
Claim 7
Dependent Claim 175 words
A stand for trailer tongues and the like, said stand comprising a stationary mounting member adapted to be attached to a generally horizontally arranged trailer tongue, an elongated, movable support structure adjustably connected to said mounting member and movable between a generally vertical position and a generally horizontal position, means adjustably fastening said support structure to said mounting member for selective movement between said vertical position and said horizontal position, said fastening means including an elongated slot at the upper end of said support member and running longitudinally of said support member and receiving a pivot pin connecting said stationary mounting member and said movable support structure, said fastening means further including a pair of rigid stop members lying on different radii about said pivot pin and on opposite sides of the pin, said stop members being spaced apart a distance to snugly receive and engage the upper end portion of said support structure, cooperating with said slot and pivot pin to maintain said support structure in either said vertical position or said horizontal position.
Claim 8
Dependent Claim 175 words
A stand for trailer tongues and the like, said stand comprising a stationary mounting member adapted to be attached to a generally horizontally arranged trailer tongue, an elongated, movable support structure adjustably connected to said mounting member and movable between a generally vertical position and a generally horizontal position, means adjustably fastening said support structure to said mounting member for selective movement between said vertical position and said horizontal position, said fastening means including an elongated slot at the upper end of said support member and running longitudinally of said support member and receiving a pivot pin connecting said stationary mounting member and said movable support structure, said fastening means further including a pair of rigid stop members lying on different radii about said pivot pin and on opposite sides of the pin, said stop members being spaced apart a distance to snugly receive and engage the upper end portion of said support structure, cooperating with said slot and pivot pin to maintain said support structure in either said vertical position or said horizontal position.
Claim 9
Dependent Claim 23 words
The stand set forth in claim 6 wherein said fastening means includes biasing means for influencing said support structure toward said stop members.
