Description
BACKGROUND OF THE INVENTION
The present invention relates generally to a mounting device and
more particularly, to a device for detachably mounting a winch
mechanism on a support structure.
Power-driven winches are presently available for a variety of
purposes. For example, many boat trailers include a power-driven
winch to facilitate the withdrawal of a boat from the water.
In most instances, the winch is fixedly and rigidly attached to a
support structure. As such, use of the winch is greatly restricted.
That is, the winch is, for all practical purposes, unavailable to
do any alternative job or serve any alternative purpose.
In addition, a power-driven winch is a relatively expensive device
and should be safely stored during periods of non-use. Where the
winch is rigidly secured to the support structure, this is
impossible. For example, during a boating excursion, the boat
trailer and attached winch are left at the loading area. Thus, the
winch is exposed to unwarranted tampering and possible damage or
destruction.
SUMMARY OF THE INVENTION
In a principal aspect, the present invention is a device for
detachably mounting a winch mechanism on a support structure. The
device includes primarily a base member, secured to the support
structure, and a winch-carrying member.
The base member includes a pair of upwardly and inwardly turned
flange portions. The flange portions are angled relative to each
other and converge towards one end of the base member.
The winch-carrying member includes a pair of downwardly extending
edge portions. The flange portions of the base member are adapted
to receive the edge portions and, upon engagement, the flange and
edge portions cooperatively define means for detachably securing
the winch-carrying member to the base member. More specifically,
the winch-carrying member and base member interlock as the edge
portions contact the flange portions.
It is thus an object of the present invention to provide a device
for detachably mounting a winch mechanism to a support structure,
thereby permitting alternative use and safe storage of the winch
mechanism.
It is a further object of the present invention to provide a winch
mounting device which is easily operated and inexpensively
manufactured.
These and other objects, advantages and features of the present
invention will become apparent in the following detailed
description.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
A preferred embodiment of the present invention is shown in the
drawing as a mounting device, generally designated 2, for
detachably securing a winch mechanism 4 to a support structure 6.
The support structure in this specific embodiment is a boat
trailer, similarly designated 6, having a forwardly extending
tongue 8. The boat trailer 6 is utilized to transport a boat 10.
The boat trailer 6 is towed by a vehicle 12 having a hitch,
generally designated 14.
As best shown in FIGS. 2 and 3, the hitch 14 includes a draft bar
16 and hitch pin 18. The draft bar 16 is rigidly fastened to the
frame (not shown) of the vehicle 12, such as by welding. The hitch
pin 18 includes a ball head 20 and a shaft or shank 22 affixed to
the draft bar 16.
The power-driven winch mechanism 4 is a standard, battery-powered
winch. Winches of this type are presently manufactured and marketed
by the Dutton-Lainson Company of Hastings, Neb.
The winch 4 includes a housing, generally designated 23, a power
supply 24, an operation lever 26, a directional switch 27 and a
power-driven spool 28. A cable or rope 30 is wound upon the spool
28. In operation, the cable 30 is attached to the boat 10 and the
spool 28 is actuated to draw the boat 10 from the water and onto
the trailer 6.
Referring to FIG. 2, the bottom portion of the housing 23 defines a
mounting plate 32. The mounting plate 32 includes a pair of
openings 34 (only one is shown) adapted to receive mounting bolts
36.
The mounting device 2 includes a winch-carrying member 38 and a
base member 40. In this preferred embodiment of the present
invention, the mounting device also includes a substantially
planar, plate member 42. The plate member 42 includes a pair of
upwardly extending, semi-circular tabs 43 located near the sides of
a central portion 44, a keyhole-shaped slot 45 at one end 46, and,
opposite the keyhole-shaped slot 46, a longitudinally extending,
elongated slot 47. The keyhole-shaped slot 45 is adapted to receive
and engage in the hitch pin 18, thereby securing the trailer 6 to
the vehicle 12.
As shown, the base member 40 and plate member 42 are rigidly
secured to the tongue 8 of the trailer 6 by a bolt 48 and locking
nut 49. The bolt 48 engages the vertically aligned openings 54 in
the bottom and top faces of the tongue 8, the elongated slot 47 in
the plate member 42 and a centrally-located opening 50 in the base
member 40, placing the round head of the bolt 48 at the bottom
opening of tongue 8 and the locking nut 49 at the top of base
member 40.
As best shown in FIG. 2, the base member 40 includes a
substantially planar, substantially trapezoidal portion 56 having a
pair of angled, converging edges, generally designated 58. The
edges 58 converge towards a first end 60 of the base member 40 and
trapezoidal portion 56.
A pair of flange portions 52 extend upwardly and inwardly from the
edges 58. More particularly, the flange portions 52 are
substantially L-shaped, having a first leg section 64 extending
upwardly and outwardly from the edge 58 and a second leg section 66
extending upwardly and inwardly from the first leg section 64. The
leg sections 64, 66 have interior surfaces 65, 67, respectively.
Extending along the edges 58, the flange portions 52 also converge
towards the first end 60 of the base member 40.
The trapezoidal mounting portion 56 also includes a slot 68 and a
pair of rectangularly-shaped apertures 70. The slot 68 extends
longitudinally from the first end 60 towards the opening 50. The
apertures 70 are opposite the first end 60 and extend transversely
from the edges 58.
In an assembled state, the tabs 43 of the plate member 42 engage
the apertures 70 of the base member 40. The engagement
substantially strengthens the structure of the mounting device
2.
Similarly, the winch-carrying member 38 includes a substantially
planar, substantially trapezoidal mounting portion 72, defining a
narrow end 74. In the preferred embodiment shown, the mounting
portion 72 is substantially equivalent, in size and shape, to the
trapezoidal mounting portion 56 of the base member 40. The mounting
portion 72 includes a longitudinally extending slot 76 near the
narrow end 74 and, opposite therefrom, a pair of transversely
extending slots 78.
In the assembled state, the slot 78 substantially aligns with the
openings 34 in the housing 23 and thereby receives bolts 36 to
secure the winch 4 to the winch-carrying member 38. The bolts 36
are threaded to engage nuts 80. As shown, the winch 4 is secured
such that the power-driven spool 28 effectively draws or pulls the
cable 30 from the narrow end 74 of the winch-carrying member 38
towards the slots 78.
The winch-carrying member 38 also includes a pair of edge portions
82 extending downwardly and outwardly from the converging edges 84
of the mounting portion 72. Each edge portion 82 is substantially
planar, elongated and rectangular and defines an upper surface 88
and end surface 90.
As shown in FIGS. 2, 3 and 4, the L-shaped flange portions 52 of
the base member 40 are adapted to receive, in the direction of
arrow 86, the edge portions 82 of the winch-carrying member 38. As
the narrow end 74 of the winch-carrying member 38 approaches and
substantially aligns with the first end 60 of the base member 40,
the upper surface 88 and end surface 90 of the edge portion 82
substantially engage the interior surface 67 of the second leg
section 66 and the interior surface 65 of the first leg section 64,
respectively. In this engaged state, shown in FIGS. 3 and 4, the
L-shaped flange portions 52 enclose and the second leg portions 66
overlap at least part of the edge portions 82, thereby detachably
securing the winch-carrying member 38 to the base member 40. As
shown, the edge portions 82 and second leg sections 66
substantially align in the engaged state.
It should be noted that operation of the winch 4 can in no way work
a disengagement or unlocking of the base member 40 and
winch-carrying member 38. Indeed, operation of the winch 4 under
heavy load conditions can only tighten the engagement of the base
and winch-carrying members 40, 38.
In the engaged or interlocking state, the elongated slots 68, 76 of
the base member 40 and winch-carrying member 38, respectively,
substantially align. Thus, the winch-carrying member 38 can be
physically locked, by means of a padlock (not shown), to the base
member 40.
An alternative use of the present invention is shown in FIG. 5. A
rope 92 is used to fasten the base member 40 and plate member 42 to
the support structure 6 (not shown).
Utilization of the mounting device 2 permits a single use winch
mechanism 4 to be readily detached from the support structure 6 and
safely stored during periods of non-use. Further, where several
winch mechanisms were previously used, only a single winch is now
required. Base members 40 of similar design are simply fixedly
attached to the various support structures 6 and the winch
mechanism 4 is transported to the place of need.
A single preferred embodiment of the present invention has been
described herein. It should be understood, however, that various
changes and modifications can be made without departing from the
true scope and spirit of the present invention, as defined by the
following claims.
