Abstract
Abstract A wind direction device for attachment to a boat shroud for indicating the direction of the wind relative to the direction of travel of the boat. The device includes several wraps of adhesive tape around a boat shroud to form an upwardly facing shoulder at a mid-point of the shroud of the boat, a bearing resting on the shoulder and having a hole through which is received the shroud, which bearing has a slit in one side and is sufficiently flexible and resilient so that the size of the slit can be varied to position the bearing around the shroud and retain the bearing on said shroud, a tubular mandrel resting on the bearing and having a bore through which the shroud is received, the mandrel having a slit traversing the length of the mandrel, the mandrel being of sufficient flexibility and resilience such that the size of the slit can be varied to position the mandrel around the shroud and retain the mandrel on the shroud, and a resilient vane connected to the periphery of the mandrel.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
175 words
In combination with a boat shroud, a wind direction device comprising: an upwardly facing shoulder secured to said shroud at a mid portion thereof; a bearing resting on said shoulder and having a hole therethrough with a slit connecting said hole and the periphery of said bearing, said shroud passing through said hole, said bearing being made of a material of sufficient flexibility and resilience such that the size of said slit can be varied to position said bearing around said shroud and retain said bearing on said shroud; a tubular mandrel engaging said bearing, said mandrel having a bore therethrough with a slit traversing the length of said mandrel connecting said bore and the periphery of said mandrel, said shroud passing through said bore, said mandrel being made of a material of sufficient flexibility and resilience such that the size of said slit in said mandrel can be varied to position said mandrel around said shroud and retain said mandrel on said shroud; and a resilient vane connected to the periphery of said mandrel.
Claim 2
Dependent Claim
175 words
In combination with a boat shroud, a wind direction device comprising: an upwardly facing shoulder secured to said shroud at a mid portion thereof; a bearing resting on said shoulder and having a hole therethrough with a slit connecting said hole and the periphery of said bearing, said shroud passing through said hole, said bearing being made of a material of sufficient flexibility and resilience such that the size of said slit can be varied to position said bearing around said shroud and retain said bearing on said shroud; a tubular mandrel engaging said bearing, said mandrel having a bore therethrough with a slit traversing the length of said mandrel connecting said bore and the periphery of said mandrel, said shroud passing through said bore, said mandrel being made of a material of sufficient flexibility and resilience such that the size of said slit in said mandrel can be varied to position said mandrel around said shroud and retain said mandrel on said shroud; and a resilient vane connected to the periphery of said mandrel.
Claim 3
Dependent Claim
14 words
The wind direction device of claim 1 wherein said mandrel has an airfoil shape.
Claim 4
Dependent Claim
34 words
The wind direction device of claim 2 wherein said vane is connected to the periphery of said mandrel such that said vane projects outwardly and substantially normal to said mandrel under all wind conditions.
Claim 5
Dependent Claim
22 words
The wind direction device of claim 3 wherein said vane has a connecting means for connecting the periphery of said mandrel thereto.
Claim 6
Dependent Claim
22 words
The wind direction device of claim 4 wherein said connecting means comprises a layer of adhesive on a portion of said vane.
Claim 7
Dependent Claim
20 words
The wind direction device of claim 5 wherein said portion of said vane substantially overlaps the periphery of said mandrel.
Claim 8
Dependent Claim
32 words
The wind direction device of claim 6 wherein said vane is substantially pennant-shaped, and said portion of said vane having an adhesive layer thereon is at the wider end of said vane.
Claim 9
Dependent Claim
17 words
The wind direction device of claim 7 wherein the periphery of said mandrel has a uniform diameter.
Claim 10
Dependent Claim
27 words
The wind direction device of claim 8 wherein the width of the wider end of said vane is substantially the same as the length of said mandrel.
Claim 11
Dependent Claim
14 words
The wind direction device of claim 9 wherein said vane is made of Mylar.
Claim 12
Dependent Claim
37 words
The wind direction device of claim 3 wherein said mandrel has a notch at each end of said slit in said mandrel, and said bearing has a notch at each end of said slit in said bearing.
Claim 13
Dependent Claim
17 words
The wind direction device of claim 1 wherein said slit in said mandrel has a spiral configuration.
Claim 14
Dependent Claim
34 words
The wind direction device of claim 12 wherein said vane is connected to the periphery of said mandrel such that said vane projects outwardly and substantially normal to said shroud under all wind conditions.
Claim 15
Dependent Claim
37 words
The wind direction device of claim 12 wherein said mandrel has a notch at each end of said slit in said mandrel, and said bearing has a notch at each end of said slit in said bearing.
