Description
FIELD OF THE INVENTION
This invention relates to fishing equipment and accessories and
more particularly, to a structure for mounting a fisherman's swivel
seat on the stationary athwartships seat of a boat.
BACKGROUND OF THE INVENTION
Brief Description of the Prior Art
Various types of seats and chair structures have been used in
fishing boats for the comfort of the fisherman while fishing, and
particularly to permit the fisherman to easily swivel from side to
side to have access to the waters on either side of the boat.
Frequently, too, the seat may swivel through 360.degree. to permit
the fisherman to fish either ahead of or astern of the boat.
Some difficulty has previously been experienced in providing a seat
which can be quickly mounted and demounted on the stationary
athwartships seats provided on various types of boats. Moreover,
the stationary or permanent seat structures which are provided in
boats vary in size and structure so that a universal mounting
arrangement for mounting a swiveling seat or chair on the permanent
seat in the boat has not been provided.
Also, in some types of detachable seat mounting structures which
have theretofore been provided, bolts or screws are extended
through the brackets of such structures into the permanent seats
located in the boats, with the result that watertight compartments
provided under these seats for buoyancy have been penetrated and
the integrity of such flotation compartments has been
destroyed.
Brief Description of the Present Invention
Broadly described, the present invention is a seat holder assembly
for mounting on the permanent athwartships seats of boats, with
such holder including a pair of spaced brackets which are
detachably interconnected by a swivel plate assembly adapted for
securement ot a swiveling chair or seat adapted for use by the
fisherman.
The seat holder assembly comprises a pair of bracket plates having
means interconnecting the bracket plates for supporting a fishing
seat. The forward bracket plate has a turned back flange portion
which is bent at an angle of 60.degree. or less to the main portion
of the forward bracket plate. The rear bracket plate has a flange
portion extending at about 90.degree. to the main portion of the
plate, and an angled finger grip flange projects at an angle to the
finger grip flange. A swivel plate assembly is preferably used to
interconnect the forward and rear bracket plates and support the
fishing seat.
The seat holder assembly is used by hooking the flange portion of
the forward bracket over the forward side of the permanent
athwartship seat of a boat, and forcing the flange portion of the
rear bracket plate down along the back side of the latter seat. The
frictional engagement of the described flange portions with the
boat seat retains the seat holder assembly firmly in position on
the permanent athwartship seat of the boat. It is released by
pulling upwardly on the angled finger grip flange.
An object of the invention is to provide a fishing seat holder
assembly which is adjustable to fit the permanent seats of various
sizes and types of fishing boats.
An additional object of the invention is to provide a seat holder
assembly which can be quickly and easily mounted on the permanent
athwartship seat of a boat to support a swiveling fishing seat
thereon.
Another object of the invention is to provide a fishing seat holder
which can be used to stably support a fishing seat in a boat
without passing screws, bolts or nails into structural members of
the boat.
Yet another object of the invention is to provide a fishing seat
holder assembly which is simple and economical in construction, but
which is rugged and durable.
Additional objects and advantages will become apparent as the
following detailed description of a preferred embodiment of the
invention is read in conjunction with the accompanying
drawings.

DETAILED DESCRIPTION OF A PERFERRED EMBODIMENT OF THE INVENTION
Referring initially to FIG. 1 of the drawings, an athwartship
permanent seat of the type which extends from side to side of a
fishing boat, such as a john boat, is shown in FIG. 1 and is
designated generally by reference numeral 10. The particular type
of seat illustrated includes a forward panel 12, a rear panel 14
and a top panel 16. These panels define a watertight enclosure
which, in many instances, is filled with a foamed synthetic resin
18 or a similar buoyant material. The top panel 16 overhangs the
forward panel 12 to provide a horizontally projecting flange
20.
The seat holder assembly of the invention includes a forward
bracket plate, designated generally by reference numeral 22, a rear
bracket plate, designated generally by reference numeral 24, and a
swivel plate assembly designated generally by reference numeral 26.
Supported on the swivel plate assembly 26 is a fishing chair or
seat 28. The relationship of the seat holder assembly to the seat
28, the athwartship permanent seat of the boat 10, and the boat in
which it is mounted (designated generally by reference numeral 30)
is illustrated in FIG. 2 of the drawings.
As will be perceptible in referring to FIGS. 3 and 4 of the
drawings, the front bracket plate 22 includes a main, substantially
monoplanar, horizontally extending portion 22a which has a pair of
bolt apertures 32 formed therethrough. The front plate 22 further
includes a turned back, downwardly projecting flange portion 22b
which defines an angle of less than 60.degree. with the main plate
portion 22a.
The rear bracket plate 24 includes a main plate portion 24a which
extends substantially horizontally, and is of substantially
monoplanar configuration. The main plate portion 24a of the rear
plate 24 includes a plurality of bolt apertures 34 which are
aligned fore and aft in the plate, and are provided for a purpose
hereinafter described. At the rear edge of the main plate portion
24a, a down turned, seat-engaging flange portion 24b is provided
and extends substantially normal to the main plate portion 24a. At
the lower edge of the flange portion 24b, a finger grip flange 24c
is provided, and is bent outwardly at an angle with respect to the
flange portion 24b.
Interconnecting the forward bracket plate 22 and the rear bracket
plate 24 is the swivel plate assembly 26. The swivel plate assembly
26 includes a lower plate 36 and an upper plate 38. These plates
are pivotally interconnected by a pivot bolt or rivet 40 extended
through apertures in the center of each of the plates, and the
upper and lower plates 36 and 38 cooperatively define bearing races
which confine ball bearings 42 as illustrated in FIG. 4. The swivel
plate assembly 26 is illustrated as secured to the fishing seat 28
by a plurality of bolts 44 extended upwardly into the seat, and is
secured to the forward bracket plate 22 by a pair of bolts 46
passed through the bolt apertures 32 in the main plate portion 22a.
The swivel plate assembly 26 is further secured to the rear bracket
plate 24 by a pair of bolts 48 extended through the rearmost bolt
apertures 34 in the main plate portion 24a of the rear plate
24.
Operation
The seat holder assembly of the invention can be used for mounting
various types of fishing chairs or seats on the permanent
athwartship seats utilized in various types of fishing boats. The
seat holder assembly is particularly well adapted for use upon the
seats of john boats, or boats of similar construction.
In using the seat holder assembly of the invention, the forward
bracket plate 22 and rear bracket plate 24 are first adjusted in
their spacing from each other so that, when the flange 22b is
hooked under the flange 20 of the permanent seat 10 as shown in
FIG. 1 of the drawings, the down turned flange portion 24b of the
rear plate 24 will then bear against the top edge of the permanent
seat 10 where the rear panel 14 intersects the top panel 16. When
the bracket plates 22 and 24 are so spaced with respect to each
other, the fishing seat 28, with the swivel plate assembly 26
attached thereto, is then rested atop the forward plate 28 and rear
plate 24 so that the bolt holes formed through the lower plate 36
of the swivel plate assembly are aligned with the bolt apertures 32
formed in the forward plate 22, and one set of the bolt apertures
34 formed in the rear plates 24. Bolts are then extended through
the aligned apertures in the lower plate 36 of the swivel plate
assembly 26 and the registering apertures through the forward plate
22 and rear plate 24. With the swivel plate assembly 26 secured in
this position, the boat seat assembly is then ready for usage.
When a fisherman seats himself in the fishing seat 28, this results
in the rear plate 24 being sprung slightly in the sense that the
downwardly depending flange portion 24b is biased rearwardly so
that it can slip down along the rear panel 14 of the permanent seat
10 to the position illustrated in FIG. 1 of the drawings. The
downwardly depending flange portion 24b is now loaded in resilient
deformation and cooperates with the flange portion 22b of the
forward plate 22 in gripping the permanent athwartship seat 10 of
the boat. When the seat is in this position, it will not spring
upwardly from this position even though the fisherman stands, and
his weight is removed from the fishing seat 28. It will be apparent
that the aligned bolt apertures 34 in the rear plate 24 make
possible the adjustment of the assembly to accommodate the
athwartship seats of various types and sizes which are found in
fishing boats, and also allows varying sizes of fisherman's seats
to be secured in the described position.
Although a preferred embodiment of the invention has been herein
described and depicted, it will be understood that various changes
and modifications in the described and illustrated structure can be
effected without departure from the basic principles of the
invention. Changes and innovations of this type are therefore
deemed to be circumscribed by the spirit and scope of the
invention, except as the same may be necessarily limited by the
apended claims or reasonable equivalents thereof.
