Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
160 words
An elevating and supporting mechanism comprising a support plate; a support arm having an end journaled with respect to said support plate; means on the other end of the support arm for affixing a load thereto; a collar having ends pivotally connected to the support arm, intermediate the ends of the arm and a spring connector means adapted to be pivoted into and out of engagement with the support arm; spring means interconnecting the support plate and the spring connector means such that a portion of the support arm is between the support plate and a portion of the spring connector means whereby the spring means biases the collar to move the support arm to an upright raised position; and means for releasably locking the support arm in one of a plurality of selected lowered positions and for maintaining the arm locked in the said selected position while a load is attached to or removed from the said support arm.
Claim 2
Dependent Claim
160 words
An elevating and supporting mechanism comprising a support plate; a support arm having an end journaled with respect to said support plate; means on the other end of the support arm for affixing a load thereto; a collar having ends pivotally connected to the support arm, intermediate the ends of the arm and a spring connector means adapted to be pivoted into and out of engagement with the support arm; spring means interconnecting the support plate and the spring connector means such that a portion of the support arm is between the support plate and a portion of the spring connector means whereby the spring means biases the collar to move the support arm to an upright raised position; and means for releasably locking the support arm in one of a plurality of selected lowered positions and for maintaining the arm locked in the said selected position while a load is attached to or removed from the said support arm.
Claim 3
Dependent Claim
39 words
A support structure and elevating means as in claim 1, further including an attachment means on the support plate to releasably hold the support arm intermedaite its length whereby the support arm is maintained in a generally upright position.
Claim 4
Dependent Claim
53 words
A support structure and elevating means as in claim 2, wherein the attachment means comprises a bracket fixed to support plate and having a saddle formed therein to receive the support arm; a strap; and means for securing the strap in place extending across the saddle when the support arm is positioned therein.
Claim 5
Dependent Claim
36 words
A support structure and elevating means as in claim 1, wherein the spring means comprises a plurality of springs each having one end fixed to the support plate and their other end attached to the collar.
Claim 6
Dependent Claim
87 words
A support structure and eleVating means as in claim 1, wherein the releasable locking means consists of a yoke having legs pivotally connected to opposite sides of the support arm; and a toothed rack of teeth mounted on the support plate, whereby a web of the yoke will engage a tooth on the rack when the support arm is pivoted to a selected lower position, whereby the yoke is wedged between the rack and the support arm to hold the support arm in the selected lower position.
Claim 7
Dependent Claim
154 words
An elevating and supporting mechanism comprising a support plate; a support arm having an end journaled with respect to said support plate; means on the other end of the support arm for affixing a load thereto; a collar pivotally connected to the support arm, intermediate the ends of the arm; spring means interconnecting the support plate and the collar such that the support arm is between the support plate and a portion of the collar whereby the spring means biases the collar to move the support arm to an upright raised position; and means including an extension extending perpendicularly out from the support plate, a post extending downwardly from the extension, and said post extending essentially parallel to the support plate having dimensions such that it fits into a stake pocket formed in the top edge of the wall of a truck body for attaching the support plate to the side of a vehicle.
