Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
95 words
In an athletic training apparatus the combination comprising a support means, an elongated rod having opposite end portions and a medial portion, means for slidingly attaching said medial portion to said support means with said opposite end portions protruding outwardly therefrom, a pair of impact members mounted on respective said rod end portions for contact with parts of the body of one or more trainees, resilient means associated with said rod for biasing said rod generally centrally of said support means with said end portions protruding substantially the same distance outwardly from said support means.
Claim 2
Dependent Claim
95 words
In an athletic training apparatus the combination comprising a support means, an elongated rod having opposite end portions and a medial portion, means for slidingly attaching said medial portion to said support means with said opposite end portions protruding outwardly therefrom, a pair of impact members mounted on respective said rod end portions for contact with parts of the body of one or more trainees, resilient means associated with said rod for biasing said rod generally centrally of said support means with said end portions protruding substantially the same distance outwardly from said support means.
Claim 3
Dependent Claim
34 words
In the apparatus as defined in claim 1 wherein each of said impact members includes an elongated base, selective means for securing each said base alternatively in an upright position and a horizontal position.
Claim 4
Dependent Claim
27 words
In the apparatus as defined in claim 1 wherein said resilient means includes a pair of springs located between said support means and respective said impact members.
Claim 5
Dependent Claim
48 words
In the apparatus as defined in claim 3 further comprising a pair of sleeves surrounding said rod and located adjacent respective said impact members, each said sleeve having a shoulder extending laterally outwardly of said rod, said springs being disposed between said support means and respective said shoulders.
Claim 6
Dependent Claim
59 words
In the apparatus as defined in claim 3 wherein said support means includes an elongated sleeve having an elongated slot therealong, said rod including a pair of mutually perpendicular passageways therethrough, said apparatus further comprising a pin guidable in said slot and disposable in either of said passageways whereby the rotative position of said impact members may be selected.
Claim 7
Dependent Claim
39 words
In the apparatus as defined in claim 1 wherein said support means includes a pair of spaced upstanding posts, said resilient means being attached to and extend between said posts, meanS for connecting said rod to said resilient means.
Claim 8
Dependent Claim
59 words
In the apparatus as defined in claim 6 wherein said resilient means includes an elongated coiled spring affixed at each end to respective said posts, said means for connecting including an element connected to and extending laterally of said rod generally medially thereof, said resilient means being located between and contacted by said element and each of said posts.
Claim 9
Dependent Claim
85 words
In the apparatus as defined in claim 6 further comprising a pin attached between said posts, said element having an end portion slidingly disposed on said pin, and a pair of slidable rings disposed on said pin on respective sides of said element end portion whereby the greater exertion of force applied to one of said impact members is transmitted by said rod to said element and thence to said ring remote from said one impact member to visually indicate such greater exertion of force.
Claim 10
Dependent Claim
25 words
In the apparatus as defined in claim 1 wherein said support means includes a generally horizontal sled and a pair of spaced posts upstanding therefrom.
Claim 11
Dependent Claim
94 words
In the apparatus as defined in claim 9 wherein said resilient means includes an elongated coiled spring surrounding said rod and connected to and between said spaced posts, an element attached to said rod generally medially thereof and extending laterally outwardly therefrom and between a pair of turns of said spring, said rod having a non-circular cross-section extending at least sufficiently along its memdial length which slides through said posts, each said post having an opening generally of complemental shape to accommodate the non-circular cross-section of said rod to inhibit rotation of said rod.
