Abstract
Abstract A punching bag is mounted on a support member that is in turn pivotally mounted in a slotted tube and limited to pivotal movement solely about the longitudinal axis of the slotted tube. The support member is spring loaded against a stop portion of the slotted tube so that the punching bag will automatically snap back directly to its normal rest position each time it is struck. A length adjustment member may be coaxially mounted at one end of the slotted tube to adjust the over-all length of the slotted tube so that a pair of door frame engaging members mounted at the outer end of the length adjustment member and at the other end of the slotted tube may be employed to releasably mount the punching bag in a door frame. Alternatively, a pair of brackets may be mounted at opposite ends of the slotted tube so that the punching bag may be fixedly mounted on a wall.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
145 words
In combination a punching bag and a mount therefor, said mount comprising: a support member having the punching bag rigidly attached to one end portion thereof; a tubular member having a slot therein; means for pivotally mounting another end portion of said support member within said tubular member with said one end portion of said support member protruding outwardly from said slot to limit said support member and the attached punching bag to pivotal movement about the longitudinal axis of said tubular member between first and second angularly spaced edges of said slot; and a spring member for spring loading said support member against movement from a normal rest position against one of said first and second edges of said slot and for automatically returning said support member and the attached punching bag directly to the normal rest position after the punching bag is struck.
Claim 2
Dependent Claim
145 words
In combination a punching bag and a mount therefor, said mount comprising: a support member having the punching bag rigidly attached to one end portion thereof; a tubular member having a slot therein; means for pivotally mounting another end portion of said support member within said tubular member with said one end portion of said support member protruding outwardly from said slot to limit said support member and the attached punching bag to pivotal movement about the longitudinal axis of said tubular member between first and second angularly spaced edges of said slot; and a spring member for spring loading said support member against movement from a normal rest position against one of said first and second edges of said slot and for automatically returning said support member and the attached punching bag directly to the normal rest position after the punching bag is struck.
Claim 3
Dependent Claim
95 words
A mount as in claim 1 wherein said means includes: a mounting bolt having a bushing fixedly mounted at one end thereof, said mounting bolt being coaxially mounted at a fixed location within said tubular member; and a pair of mounting rings fixedly mounted at opposite sides of said other end portion of said support member, one of said mounting rings being rotatably supported upon a portion of said mounting bolt and the other of said mounting rings being rotatably supported upon a portion of said bushing at a fixed location within said tubular member.
Claim 4
Dependent Claim
46 words
A mount as in claim 2 wherein said spring member comprises a coil spring coaxially supported upon said mounting bolt between aid mounting rings, said coil spring having one end portion fixedly engaged with said bushing and another end portion spring loaded against said support member.
Claim 5
Dependent Claim
62 words
A mount as in claim 3 including: a length adjustment mechanism coaxially mounted at one end of said tubular member for adjusting the over-all length of said mount; a first door frame engaging member rotatably mounted at the outer end of said length adjustment mechanism; and a second door frame engaging member fixedly mounted at the other end of said tubular member.
Claim 6
Dependent Claim
53 words
A mount as in claim 4 wherein said length adjustment mechanism comprises: a second tubular member telescopically fitting around a portion of said first-mentioned tubular member; and a mounting bolt coaxially mounted within said second tubular member and screwed into mounting member fixedly mounted at said one end of said first-mentioned tubular member.
Claim 7
Dependent Claim
53 words
A mount as in claim 1 including: a length adjustment mechanism mounted at one end of said mount for adjusting the over-all length of said mount; a first mounting member mounted at the outer end of said length adjustment mechanism; and a second mounting member mounted at the other end of said mount.
Claim 8
Dependent Claim
38 words
A mount as in claim 6 wherein: said first mounting member is rotatably mounted at the outer end of said length adjustment mechanism; and said second mounting member is fixedly mounted at the other end of said mount.
