Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
115 words
A tricycle push stick for attachment to a tricycle frame for pushing or pulling, comprising: an elongated member having a longitudinal axis; a handle mounted at one end of said elongated member; a releasable attachment member fixedly mounted at the other end of said elongated member; said releasable attachment member including an elongated opening having a longitudinal axis parallel to the longitudinal axis of said elongated member and an angled slot cooperating with said opening which allows the frame of the tricycle into the opening only when the angle of the tricycle frame is the same as the angle of the slot, thereby preventing unintentional disengagement of the tricycle from the push stick during use.
Claim 2
Dependent Claim
115 words
A tricycle push stick for attachment to a tricycle frame for pushing or pulling, comprising: an elongated member having a longitudinal axis; a handle mounted at one end of said elongated member; a releasable attachment member fixedly mounted at the other end of said elongated member; said releasable attachment member including an elongated opening having a longitudinal axis parallel to the longitudinal axis of said elongated member and an angled slot cooperating with said opening which allows the frame of the tricycle into the opening only when the angle of the tricycle frame is the same as the angle of the slot, thereby preventing unintentional disengagement of the tricycle from the push stick during use.
Claim 3
Dependent Claim
27 words
The tricycle push stick of claim 1 wherein said releasable attachment member includes side legs and said angled slot is located in one of said side legs.
Claim 4
Dependent Claim
31 words
The tricycle push stick of claim 2 wherein the angle of said slot is either approximately 45 degrees or 135 degrees with reference to the longitudinal axis of said elongated member.
Claim 5
Dependent Claim
17 words
The tricycle push stick of claim 1 wherein said opening is in the form of an oval.
Claim 6
Dependent Claim
31 words
The tricycle push stick of claim 4 wherein the angle of said slot is either approximately 45 degrees or 135 degrees with reference to the longitudinal axis of said elongated means.
Claim 7
Dependent Claim
24 words
The tricycle push stick of claim 1 wherein the thickness of said releasable attachment member is greater than the thickness of said elongated member.
Claim 8
Dependent Claim
19 words
The tricycle push stick of claim 1 wherein the releasable attachment member is integrally formed with the elongated member.
Claim 9
Dependent Claim
112 words
A tricycle in combination with a push stick for attachment to the tricycle frame for pushing or pulling, comprising: an elongated member having a longitudinal axis; a handle mounted at one end of said elongated member; a releasable attachment member mounted at the other end of said elongated member; said releasable attachment member includes side legs, an opening and an angled slot in one of said side legs cooperating with said opening which allows the frame of the tricycle into the opening only when the angle of the tricycle frame is the same as the angle of the slot, thereby preventing unintentional disengagement of the tricycle from the push stick during use.
Claim 10
Dependent Claim
112 words
A tricycle in combination with a push stick for attachment to the tricycle frame for pushing or pulling, comprising: an elongated member having a longitudinal axis; a handle mounted at one end of said elongated member; a releasable attachment member mounted at the other end of said elongated member; said releasable attachment member includes side legs, an opening and an angled slot in one of said side legs cooperating with said opening which allows the frame of the tricycle into the opening only when the angle of the tricycle frame is the same as the angle of the slot, thereby preventing unintentional disengagement of the tricycle from the push stick during use.
Claim 11
Dependent Claim
17 words
The tricycle push stick of claim 8 wherein said opening is in the form of an oval.
Claim 12
Dependent Claim
31 words
The tricycle push stick of claim 8 wherein the angle of said slot is either approximately 45 degrees or 135 degrees with reference to the longitudinal axis of said elongated member.
Claim 13
Dependent Claim
24 words
The tricycle push stick of claim 8 wherein the thickness of said releasable attachment member is greater than the thickness of said elongated member.
Claim 14
Dependent Claim
127 words
A tricycle push stick for attachment to a tricycle frame for pushing or pulling, comprising an elongated member having a longitudinal axis; a handle mounted at one end of said elongated member; a universally adaptable attachment member rigidly mounted at the other end of said elongated member; said universally adaptable attachment member including an elongated opening having a longitudinal axis parallel to the longitudinal axis of said elongated member and an angled slot located in a side leg of said attachment member to cooperate with said opening to allow the frame of the tricycle into the opening only when the angle of the tricycle frame is the same as the angle of the slot, thereby preventing unintentional disengagement of the tricycle from the push stick during use.
Claim 15
Dependent Claim
127 words
A tricycle push stick for attachment to a tricycle frame for pushing or pulling, comprising an elongated member having a longitudinal axis; a handle mounted at one end of said elongated member; a universally adaptable attachment member rigidly mounted at the other end of said elongated member; said universally adaptable attachment member including an elongated opening having a longitudinal axis parallel to the longitudinal axis of said elongated member and an angled slot located in a side leg of said attachment member to cooperate with said opening to allow the frame of the tricycle into the opening only when the angle of the tricycle frame is the same as the angle of the slot, thereby preventing unintentional disengagement of the tricycle from the push stick during use.
Claim 16
Dependent Claim
31 words
The tricycle push stick of claim 12 wherein the angle of said slot is either approximately 45 degrees or 135 degrees with reference to the longitudinal axis of said elongated means.
Claim 17
Dependent Claim
25 words
The tricycle push stick of claim 12 wherein the thickness of said universally adaptable attachment member is greater than the thickness of said elongated member.
