Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
237 words
A releasable ladder fastener, comprising: a ladder strap portion including a pair of elongate parallel side rails joined by a plurality of spaced interposed rungs; fastener mounting means for securing the fastener to a mounting surface formed adjacent an end of the strap portion; and resilient latching means for engaging the side rails of the strap portion formed on the fastener mounting means, the latching means including two spaced apart opposed resiliently mounted locking members that each engage on of the side rails within respective side rail latching recesses of the locking members to releasably lock the resilient latching means within the ladder strap portion, the locking members as molded being spaced apart an amount greater than the inner width of the spaced apart rails such that as the locking members are inserted between the rails the locking members are displaced inwardly whereby the locking members are resiliently biased outwardly to releasably engage the side rails within the side rail latching recesses, said locking members being moveable from a first latched position wherein said locking members are spaced apart an amount greater than the inner width of said spaced apart side rails to a second position wherein said locking members are biased toward one another and spaced apart an amount less than the inner width of said spaced apart side rails whereby said locking members may be biased toward one another and removed from said side rails.
Claim 2
Dependent Claim
237 words
A releasable ladder fastener, comprising: a ladder strap portion including a pair of elongate parallel side rails joined by a plurality of spaced interposed rungs; fastener mounting means for securing the fastener to a mounting surface formed adjacent an end of the strap portion; and resilient latching means for engaging the side rails of the strap portion formed on the fastener mounting means, the latching means including two spaced apart opposed resiliently mounted locking members that each engage on of the side rails within respective side rail latching recesses of the locking members to releasably lock the resilient latching means within the ladder strap portion, the locking members as molded being spaced apart an amount greater than the inner width of the spaced apart rails such that as the locking members are inserted between the rails the locking members are displaced inwardly whereby the locking members are resiliently biased outwardly to releasably engage the side rails within the side rail latching recesses, said locking members being moveable from a first latched position wherein said locking members are spaced apart an amount greater than the inner width of said spaced apart side rails to a second position wherein said locking members are biased toward one another and spaced apart an amount less than the inner width of said spaced apart side rails whereby said locking members may be biased toward one another and removed from said side rails.
Claim 3
Dependent Claim
27 words
A fastener as set forth in claim 1, wherein the resilient latching means includes means for releasably engaging on of the rungs within a rung latching recess.
Claim 4
Dependent Claim
58 words
A fastener as set forth in claim 1, wherein the resilient latching means includes a locking ridge formed on a lower surface of each of the resilient locking members adjacent a rung latching recess, the locking ridge being disposed to releasably engage a rung of the ladder strap upon insertion of the resilient latching means between adjacent rungs.
Claim 5
Dependent Claim
53 words
A fastener as set forth in claim 3, wherein the resilient locking members each include an area of reduced thickness formed by a hinge recess in an inner peripheral edge of the locking member, between the side rail latching recesses and the fastener mounting means to increase the flexibility of the locking members.
Claim 6
Dependent Claim
40 words
A fastener as set forth in claim 4, wherein each of the resilient locking members projects away from the ladder strap portion and outwardly of the fastener mounting means at an angle to the plane of the ladder strap portion.
Claim 7
Dependent Claim
61 words
A fastener as set forth in claim 1, wherein each of the resilient locking members includes a locking barb formed on an outer peripheral edge of the locking member adjacent the side rail latching recess, the locking barbs being disposed to releasably engage the side rails of the ladder strap portion upon insertion of the resilient latching means between adjacent rungs.
Claim 8
Dependent Claim
51 words
A fastener as set forth in claim 6, wherein the resilient locking members each include an area of reduced thickness formed by a hinge recess in an inner peripheral edge of the locking member, between the locking barb and the fastener mounting means to increase the flexibility of the locking members.
Claim 9
Dependent Claim
40 words
A fastener as set forth in claim 7, wherein each of the resilient locking members projects away from the ladder strap portion and outwardly of the fastener mounting means at an angle to the plane of the ladder strap portion.
Claim 10
Dependent Claim
208 words
A releasable ladder fastener, comprising: a planar ladder strap portion having a pair of elongate parallel rails joined by a plurality of spaced interposed rungs; fastener mounting means for securing the fastener to a mounting surface, formed adjacent an end of the strap portion; and two elongate resilient locking members formed on the fastener mounting means, the locking members including opposed locking barbs formed on their respective outer peripheral edges, the locking barbs as molded being spaced apart an amount greater than the inner width of the spaced apart rails such that as the barbs are inserted between the rails the locking members are resiliently displaced inwardly and as the barbs are inserted beyond the rails the barbs are resiliently biased outwardly against the rails to releasably engage the rails of the ladder strap portion, said locking members being moveable from a first latched position wherein said locking members are spaced apart an amount greater than the inner width of said spaced apart rails to a second position wherein said locking members are biased toward one another and spaced apart an amount less than the inner width of said spaced apart rails whereby said locking members may be biased toward on another and removed from said side rails.
Claim 11
Dependent Claim
208 words
A releasable ladder fastener, comprising: a planar ladder strap portion having a pair of elongate parallel rails joined by a plurality of spaced interposed rungs; fastener mounting means for securing the fastener to a mounting surface, formed adjacent an end of the strap portion; and two elongate resilient locking members formed on the fastener mounting means, the locking members including opposed locking barbs formed on their respective outer peripheral edges, the locking barbs as molded being spaced apart an amount greater than the inner width of the spaced apart rails such that as the barbs are inserted between the rails the locking members are resiliently displaced inwardly and as the barbs are inserted beyond the rails the barbs are resiliently biased outwardly against the rails to releasably engage the rails of the ladder strap portion, said locking members being moveable from a first latched position wherein said locking members are spaced apart an amount greater than the inner width of said spaced apart rails to a second position wherein said locking members are biased toward one another and spaced apart an amount less than the inner width of said spaced apart rails whereby said locking members may be biased toward on another and removed from said side rails.
