Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
142 words
A safety guard for an exposed linkage of an extendable device having at least a pair of pivotal connections between links thereof and at least a pair of spaced apart fasteners mounted on at least one link thereof, said safety guard comprising a substantially planar body member having a length at least equal to the distance between two pivotal connections of the linkage in its extended position and a width at least equal to the width of the linkage in its retracted postion at its widest exposed portion formed by at least a pair of links pivotally interconnEcted, said member being fastenable to one side of the linkage to a pair of fasteners of the linkage, whereby said member is transportable with the linkage to restrict access to the space between adjacent links of the linkage in all positions of the linkage.
Claim 2
Dependent Claim
142 words
A safety guard for an exposed linkage of an extendable device having at least a pair of pivotal connections between links thereof and at least a pair of spaced apart fasteners mounted on at least one link thereof, said safety guard comprising a substantially planar body member having a length at least equal to the distance between two pivotal connections of the linkage in its extended position and a width at least equal to the width of the linkage in its retracted postion at its widest exposed portion formed by at least a pair of links pivotally interconnEcted, said member being fastenable to one side of the linkage to a pair of fasteners of the linkage, whereby said member is transportable with the linkage to restrict access to the space between adjacent links of the linkage in all positions of the linkage.
Claim 3
Dependent Claim
20 words
The safety guard of claim 1 wherein said member is pivotally connected to a pair of fasteners of the linkage.
Claim 4
Dependent Claim
50 words
The safety guard of claim 2 wherein one of said pivotal connections of said member to the linkage includes a slidable connection whereby said member is substantially unaffected by a change in the distance between the pair of pivotal connections of the linkage interconnecting pairs of links of the linkage.
Claim 5
Dependent Claim
46 words
The safety guard of claim 3 wherein said slidable connection comprises a portion of said member defining an elongated slot adapted to receive an extension of a fastener member of the linkage for sliding movement within the elongated slot defined by said portion of said member.
Claim 6
Dependent Claim
49 words
The safety guard of claim 1 wherein said member is adapted to be fastened to two fasteners mounted on one selected link of the linkage adjacent the ends of the link, whereby said member is transportable with the selected link between the contracted and extended positions of the linkage.
