Abstract
Abstract A taillight assembly for boat trailers. The assembly comprises a taillight, and means for mounting the taillight on a trailer. Means are provided for raising and lowering the taillight from and to lower and higher elevations, without manually adjusting the position of the taillight, and while keeping the taillight pointed in a horizontal direction rearward of the trailer. The lower elevation is useful in transporting the boat, and the higher elevation is useful for launching the boat. Keeping the taillight pointed horizontal and rearward of the trailer ensures that the light will be visible both on the road, and while launching and reloading the boat onto the trailer. Means are provided for holding the taillight at the first and second elevations.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
94 words
A taillight assembly for a boat trailer, comprising: (a) a taillight for the trailer; (b) means for mounting the taillight on the trailer; (c) means for raising the taillight from a first elevation useful in transporting a boat to a second elevation useful for launching the boat, and for lowering the taillight from the second elevation to the first elevation, while keeping the taillight pointed in a horizontal direction rearward of the trailer without manually adjusting the position of the taillight; and (d) means for holding the taillight at the first and second elevations.
Claim 2
Dependent Claim
94 words
A taillight assembly for a boat trailer, comprising: (a) a taillight for the trailer; (b) means for mounting the taillight on the trailer; (c) means for raising the taillight from a first elevation useful in transporting a boat to a second elevation useful for launching the boat, and for lowering the taillight from the second elevation to the first elevation, while keeping the taillight pointed in a horizontal direction rearward of the trailer without manually adjusting the position of the taillight; and (d) means for holding the taillight at the first and second elevations.
Claim 3
Dependent Claim
21 words
The taillight assembly of claim 1, further comprising: (e) automatic means for locking the taillight into the first and second elevations.
Claim 4
Dependent Claim
17 words
The taillight assembly of claim 1, further comprising: (e) means for fastening a boat to the trailer.
Claim 5
Dependent Claim
61 words
The taillight assembly of claim 3, wherein the means for fastening the boat to the trailer include: (f) a flexible member having a length such that when disposed above the boat and attached to a second taillight assembly on the opposite side of the boat, the flexible member will be drawn taut when both taillights are disposed at the first elevation.
Claim 6
Dependent Claim
127 words
The taillight assembly of claim 2, wherein the means for locking the taillight into the first elevation include: (f) first and second interconnected elongated, rigid members which in combination support the taillight, the first and second elongated members parallel to one another, the first member lying below the second member when the members are horizontal, the first member including a notch to receive part of a locking device; and (g) a locking device comprising a horizontal portion; and vertical portion; and L-shaped member; and a spring connecting the vertical portion to the L-shaped member, to keep the device locked until the spring is released, the horizontal portion of the device sized to protrude through the notch in the first elongated rigid member when the device is locked.
Claim 7
Dependent Claim
28 words
The taillight assembly of claim 1, wherein the means for mounting the taillight on the trailer comprise: (e) a pivotable frame fastened to the frame of the trailer.
Claim 8
Dependent Claim
73 words
The taillight assembly of claim 6, wherein the pivotable frame comprises: (f) first and second substantially parallel, elongated, rigid members, pivotally connected at one end to first and second vertical rigid members by first and second pivot pins, respectively, the vertical members offset from one another both horizontally and vertically, the rigid elongated members connected to one another at their other ends by a pivotable member by third and fourth pivot pins, respectively.
Claim 9
Dependent Claim
64 words
The taillight assembly of claim 7, wherein the means for raising the taillight from the first elevation to the second elevation, and for lowering the taillight from the second to the first elevation comprise: (g) means for fastening the taillight to the pivotable member in a configuration such that the beam from the taillight is directed in a horizontal direction rearward of the trailer.
Claim 10
Dependent Claim
85 words
The taillight assembly of claim 8, wherein the straight-line distance between the first and second pivot pins is substantially equal to the straight-line distance between the third and fourth pivot pins, and the straight-line distance between the first and third pivot pins is substantially equal to the straight-line distance between the second and fourth pivot pins, thereby ensuring that the taillight remains pointed in a horizontal direction rearward of the trailer as the position of the taillight is interchanged between the first and second elevations.
