Abstract
Abstract A wheeled device for carrying sail boards comprises a support on which the sail board float is set and a fast coupling system for receiving the said board mast. The fast coupling system has two couplers in which the mast is set. Once the sail board mast has been secured to the couplers, the wheeled device is positioned with its front end resting on the ground or in a trailer position on the wheeled device. The axle of the wheels is located far enough back for gravity to jam the mast between the couplers.

Claims Analysis
Total Claims: 21
Claim 1
Independent Claim
130 words
A wheeled device for for carrying sail boards, said device comprising a support on which a sail board float is set, a fast coupling system comprising a first generally U-shaped coupler facing downwardly, a second generally U-shaped coupler facing upwardly, said first and second couplers being aligned to receive a sail board mast which sets the sail board mast below a position for receiving the sail board float set on the said support, wherein one of the said two couplers blocks the mast from moving downwardly and from moving sideward along a rather long portion and the other of said two couplers blocking the mast from moving upwardly (or downwardly) without providing sideward blocking, and a spaced parallel pair of wheels mounted to roll along paths parallel to said mast.
Claim 2
Dependent Claim
130 words
A wheeled device for for carrying sail boards, said device comprising a support on which a sail board float is set, a fast coupling system comprising a first generally U-shaped coupler facing downwardly, a second generally U-shaped coupler facing upwardly, said first and second couplers being aligned to receive a sail board mast which sets the sail board mast below a position for receiving the sail board float set on the said support, wherein one of the said two couplers blocks the mast from moving downwardly and from moving sideward along a rather long portion and the other of said two couplers blocking the mast from moving upwardly (or downwardly) without providing sideward blocking, and a spaced parallel pair of wheels mounted to roll along paths parallel to said mast.
Claim 3
Dependent Claim
67 words
The wheeled device according to claim 1, wherein the two couplers are a front coupler and a rear coupler, the front coupler blocking the mast from moving sideward and upwardly, and the rear coupler blocking the mast from moving sideward and downwardly, each coupler being made of a groove for receiving a cross-section of the mast and being open for enabling an entrance of the mast cross-section.
Claim 4
Dependent Claim
57 words
The wheeled device according to claim 1, which is further comprised of front and rear crosspieces each having one of said mast couplers and being interconnected by two side-frames constituting the sail board float support, a suspension coupled to an axle for supporting the wheels, the assembly of crosspieces and side-frames being secured to said suspension member.
Claim 5
Dependent Claim
65 words
The wheeled device according to claim 3, wherein the cross pieces are shaped to form said U-shape, each U having a large mouth, the side vertical branches of the U-shaped cross pieces being secured under the side-frames, said side vertical branches being long enough for to receive the sail board wishbone on the cross pieces with the sail board float being set on the side-frames.
Claim 6
Dependent Claim
53 words
A device for carrying a sail board comprising a wheeled device according to claim 3, which also comprises a protecting device for protecting one end of the sail board mast which allows the use of the sail board mast as a beam, the protected mast end being in front of the wheeled device.
Claim 7
Dependent Claim
28 words
The wheeled device according to claim 3, wherein portion of the side-frames project rearwardly to serve as stops when the wheeled device is moved in a backward direction.
Claim 8
Dependent Claim
65 words
The wheeled device according to claim 6, wherein the cross pieces are shaped to form said U-shape, each U having a large mouth, the side vertical branches of the U-shaped cross pieces being secured under the side-frames, said side vertical branches being long enough for to receive the sail board wishbone on the cross pieces with the sail board float being set on the side-frames.
Claim 9
Dependent Claim
53 words
A device for carrying a sail board comprising a wheeled device according to claim 6, which also comprises a protecting device for protecting one end of the sail board mast which allows the use of the sail board mast as a beam, the protected mast end being in front of the wheeled device.
Claim 10
Dependent Claim
84 words
The wheeled device according to claim 1 further comprising a support for a sail board float, said support having a front part and a rear part, the middle of the rear part having a rear stop secured to a suspension member coupled to the axle of the wheels, said suspension member being coupled to the front part by means of a side-frame which is located on one side of the rear stop and is secured to both the front part and the front stop.
Claim 11
Dependent Claim
53 words
A device for carrying a sail board comprising a wheeled device according to claim 9, which also comprises a protecting device for protecting one end of the sail board mast which allows the use of the sail board mast as a beam, the protected mast end being in front of the wheeled device.
Claim 12
Dependent Claim
23 words
The wheeled device according to claim 9, wherein there are two of said side-frames for coupling the rear part to the front part.
Claim 13
Dependent Claim
53 words
A device for carrying a sail board comprising a wheeled device according to claim 11, which also comprises a protecting device for protecting one end of the sail board mast which allows the use of the sail board mast as a beam, the protected mast end being in front of the wheeled device.
Claim 14
Dependent Claim
25 words
The wheeled device according to claim 2, wherein each of said U-shaped couplers has an angular V-shaped bottom to provide a point-clamping of the mast.
Claim 15
Dependent Claim
25 words
The wheeled device according to claim 1, wherein each of said U-shaped couplers has an angular V-shaped bottom to provide a point-clamping of the mast.
Claim 16
Dependent Claim
54 words
The wheeled device according to claim 14, and an axle for supporting the spaced pair of wheels, said axle being located far enough behind the center of gravity of said device when unloaded to jam the mast between the said couplers, whereby setting the sail board float on the support increasing the jamming action.
Claim 17
Dependent Claim
54 words
The wheeled device according to claim 10, and an axle for supporting the spaced pair of wheels, said axle being located far enough behind the center of gravity of said device when unloaded to jam the mast between the said couplers, whereby setting the sail board float on the support increasing the jamming action.
Claim 18
Dependent Claim
54 words
The wheeled device according to claim 1, and an axle for supporting the spaced pair of wheels, said axle being located far enough behind the center of gravity of said device when unloaded to jam the mast between the said couplers, whereby setting the sail board float on the support increasing the jamming action.
