Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
140 words
A flotation device, comprising: (a) an elongated staff, (b) an annular buoyant member, (c) means for mounting the buoyant member to the staff, comprising: (a) a cylindrical body having a recessed sidewall, a planar top wall and a planar bottom wall, the body being provided with an internal passageway having a diameter less than that of the staff such that the body is frictionally retained on the staff. (d) a visually observable signalling device detachably mounted onto the staff at one end thereof, and (e) means for detachably locking the visually observable signalling device onto the staff, the locking means, comprising: (1) a biassed member secured to the visually observable device, and (2) means for receiving the biassed member formed on the staff, the receiving means releasably retaining the biassed member upon the mounting of the device to the staff.
Claim 2
Dependent Claim
140 words
A flotation device, comprising: (a) an elongated staff, (b) an annular buoyant member, (c) means for mounting the buoyant member to the staff, comprising: (a) a cylindrical body having a recessed sidewall, a planar top wall and a planar bottom wall, the body being provided with an internal passageway having a diameter less than that of the staff such that the body is frictionally retained on the staff. (d) a visually observable signalling device detachably mounted onto the staff at one end thereof, and (e) means for detachably locking the visually observable signalling device onto the staff, the locking means, comprising: (1) a biassed member secured to the visually observable device, and (2) means for receiving the biassed member formed on the staff, the receiving means releasably retaining the biassed member upon the mounting of the device to the staff.
Claim 3
Dependent Claim
52 words
The device of claim 1 wherein: (a) the biassed member comprises a spring circular pin secured to the observable device, and (b) the receiving means is defined by an annular groove formed in the snap, the pin being biassed into the groove upon the mounting of the observable device onto the staff.
Claim 4
Dependent Claim
71 words
The flotation device of claim 1 wherein the visually observable signalling device comprises: (a) means for mounting the signalling device onto the staff, the means comprising: (1) a right angle conduit having a first elongated leg and a second leg, (2) the elongated leg being telescopable onto the staff, (3) a rod projecting outwardly from the second leg, and (b) a visually observable sheet material secured to the means for mounting.
Claim 5
Dependent Claim
19 words
The flotation device of claim 1 wherein: the annular member is formed from an ultraviolet light stabilized vinyl material.
Claim 6
Dependent Claim
42 words
The flotation device of claim 1 wherein the annular member is dielectrically sealed to the means for mounting, said means being in the shape of a spool, the top and bottom walls thereof comprising flexible grommets, said passageway extending through each grommet.
Claim 7
Dependent Claim
39 words
The flotation device of claim 5 wherein: the annular member is an inflatable member, the annular member comprising means for orally inflating the member, and wherein upon inflating the member the grommets flex outwardly away from toward each other.
Claim 8
Dependent Claim
27 words
The flotation device of claim 1 wherein: the staff comprises: (a) a pair of detachably connectable telescoping sections, and (b) means for detachably interconnecting the sections together.
Claim 9
Dependent Claim
22 words
The flotation device of claim 1, wherein: the annular member is inflatable, the annular member comprising means for orally inflating the member.
Claim 10
Dependent Claim
18 words
The flotation device of claim 1 which further comprises: a weight disposed at one end of the staff.
Claim 11
Dependent Claim
96 words
A flotation device, comprising: (a) an elongated staff, (b) an annular buoyant member, (c) means for mounting the buoyant member to the staff, comprising: a cylindrical body having a recessed sidewall, a planar top wall and a planar bottom wall, the body being provided with an internal passageway having a diameter less than that of the staff such that the body is frictionally retained on the staff, (d) a visually observable signalling device detachably mounted onto the staff at one end thereof, and (e) means for detachably locking the visually observable signalling device onto the staff.
Claim 12
Dependent Claim
96 words
A flotation device, comprising: (a) an elongated staff, (b) an annular buoyant member, (c) means for mounting the buoyant member to the staff, comprising: a cylindrical body having a recessed sidewall, a planar top wall and a planar bottom wall, the body being provided with an internal passageway having a diameter less than that of the staff such that the body is frictionally retained on the staff, (d) a visually observable signalling device detachably mounted onto the staff at one end thereof, and (e) means for detachably locking the visually observable signalling device onto the staff.
