ELEVATING SKIPPER CHAIR FOR BOATS
Abstract
A control station for a motor boat is constructed to permit
operation of the boat from either a deck-side location or a flying
bridge using a single set of controls and control panel. The
controls and control panel are rigidly secured to an operator's
chair which is supported by a lifting mechanism. When the lifting
mechanism is activated, the control panel, controls and operator's
chair are all moved between a first position adjacent the deck and
a second position at the flying bridge. A flexible umbilical cord
assures uninterrupted connection between the control station and
the operating mechanism.

Description
This invention relates to the control of mobile vehicles, and, more
particularly, to a control station which permits operation of a
vehicle from different elevations.
With many types of vehicles for land, marine, and airborne usage,
it is desirable or necessary to be able to control the vehicle from
different elevations. The problem is exemplified in many small
commercial and pleasure boats where it is found desirable to have a
first control station on the deck of the boat and a second control
station at a flying bridge. Although the flying bridge offers the
skipper of the boat an unobstructed view, the deck-side control
station is normally located within a closed cabin where the skipper
is protected from the wind and weather, and, at the same time, is
in a better position to carry on conversation with other
passengers.
The above-described flying bridge has heretofore been largely
associated with the "luxury type" of yacht. In recent years, the
houseboat has become much more popular than the yacht because of
its greater room at a lower cost. The usual houseboat type of
structure, is, however, somewhat limited in its maneuverability and
is not suitable for certain water sports such as skiing, because
the operator is confined to an area within the cabin of the boat
where his view is somewhat restricted.
It is, therefore, the primary object of the present invention to
provide a vehicle control station which permits operation of a
vehicle from different elevational levels utilizing a single set of
controls.
Another important object of this invention is to provide a flying
bridge control station of the type previously found in luxury
yachts, but wherein the cost of duplicating the boat controls is
greatly reduced by coupling a single set of controls and control
panel therefor with an operator's chair which is disposed upon a
lifting mechanism and is capable of moving from a deck-side
location to a flying bridge location.
As a corollary to the above object, an aim of this invention is to
provide a vehicle such as a boat which has a hatch in the cabin
immediately above the deck-side operator's station and wherein the
operator's station includes elevating mechanism for raising the
operator's chair and control panel to a location where the skipper
of the boat is above the roof of the cabin and has an unobstructed
view thereby resulting in the houseboat having many of the
attributes previously associated only with luxury yachts having
dual control stations.
Still another one of the aims of the present invention is a vehicle
control station for permitting operation of a vehicle from
different elevational levels and wherein the lifting mechanism for
elevating the control station is capable of being powered by
electricity, air, a hydraulic motor, or other equivalent means.
Still other objects of the invention will be made clear or become
apparent from the following descriptions and accompanying
figures.
In the drawing:
FIG. 1 is a side elevational view of a type of marine vehicle with
the novel control station of the present invention installed
thereon and shown in both its lowered and raised positions;
FIG. 2 is an enlarged, side elevational view of the operator's
chair of the control station of the present invention with portions
being broken away to illustrate details of the lifting mechanism;
and
FIG. 3 is an enlarged, perspective view of the vehicle control
station, its stabilizing structure and associated power source.
Referring initially to FIG. 1 wherein a marine vehicle or boat of
one representative type is designated generally by the numeral 10,
it is seen that the boat 10 includes a hull 12 having a deck 14,
with an enclosed cabin 16 disposed atop the deck. The boat is
propelled by a motor, the propeller of which is visible in the far
right-hand corner of FIG. 1 and designated by the numeral 18. A
rudder 20 is an integral part of the propeller-supporting
structure. A sliding hatch 22 in the roof of the cabin 16 is
immediately above a control station for the boat 10 which has been
designated generally by the numeral 24.
The control station 24 is shown in greater detail in FIGS. 2 and 3
wherein it is seen that the station includes a control panel 26,
structure for supporting the operator in the form of a chair 28,
and lifting mechanism designated generally by the numeral 30 for
moving the panel 26 and the chair 28 between different elevational
levels. The chair 28 is mounted upon a base plate 32 and includes a
foot support 34, and an extension arm 36 for mounting the control
panel 26.
The control panel 26 mounts all of the controls and gauges for
operating the boat 10. It includes a steering control 38 and a
throttle control 40. A laterally extending, hollow rectangular
housing 42 which is rigid with the control panel 26 encloses an
umbilical cord designated generally by the numeral 44 which is
comprised of the various cables and wires for coupling the controls
with the operational components of the boat. For example, the
umbilical cord 44 would include appropriate cables for connecting
the steering control 38 and the throttle control 40 with the
steering rudder 20 and the boat engine (not shown)
respectively.
From FIG. 2, it is seen that the lifting mechanism 30 actually
supports the chair 28 and the control panel 26. The mechanism 30
includes a first rigidly mounted tubular sleeve 46 of rectangular
cross-section, and a second tubular sleeve 48 of complemental
cross-section which is telescoped within the first sleeve 46 and is
rigid with the base plate 32. The sleeve 48 is coupled with a jack
screw 50 by a complementally threaded block 52 which is rigid with
the sleeve 48 at the lower end of the same. The jack screw 50 is
provided with a relatively large bevel gear 54 at its base and is
driven by a motor 56 through a pair of universally coupled shafts
58 and 60, the former of which is coupled with the output of the
motor and the latter of which is rigid with a relatively small
second bevel gear 62. The motor 56 is preferably powered from a
portable source such as a 12-volt battery 64 of the type well known
to those skilled in the art. A lead wire 66 which is an integral
part of the circuit of the power source 64 places the motor 56
under the control of an over-center switch 68 which is located on
the control panel 26. A band 70 which extends around the outer
perimeter of the sleeve 46 serves to mount a pair of stabilizing
legs 72.
In normal operation, a skipper of the boat 10 will operate the boat
with the control station 24 disposed in its lowered position within
the cabin 16 and adjacent the deck 14. This allows the skipper to
converse with other passengers and also offers protection from
surface winds. All of the controls for operating the boat 10 are
readily accessible to the skipper when he is seated in the chair 28
as a result of the close proximity of control panel 26.
In certain instances, however, as for example when it is desired to
use the boat 10 for pulling skiers, it is essential that the boat
be operated from a flying bridge where the skipper has an
unobstructed view. Thus, the hatch 22 is opened to present a flying
bridge immediately above the control station 24. The switch 68 is
then thrown to activate the motor 56 and rotate the jack screw 50.
This in turn causes the chair 28 and control panel 26 to be moved
to their alternative positions at the elevated level adjacent the
flying bridge which is presented upon opening the hatch 22. With
the skipper's chair 28 in this location, the operator's head
projects above the roof of the cabin 16 a sufficient distance to
permit an unobstructed view of the area surrounding the boat 10. At
the same time, the operator has complete access to the control
panel 26 and the controls mounted thereon. By virtue of the
flexible umbilical cord 44 an uninterrupted connection between the
controls and the operating components of the boat is assured even
during the raising and lowering of the control station 24. When it
is desired to again move the control station 24 to the lower
elevation illustrated in FIG. 1, the switch 68 is simply moved in
the opposite direction to reverse the motor 56 and turn the screw
50 in the opposite direction to thereby lower the chair 28.
It will be apparent, that not only has the present invention made
it possible to provide a flying bridge control station on many
types of marine craft which were heretofore not suited for such a
station, but in addition has significantly reduced the cost of
providing a flying bridge control station by eliminating the need
for a dual set of controls. While the invention has been described
with particular reference to marine vehicles, it is contemplated
that the invention will also find use in many types of overland and
airborne vehicles.
Difficulties in providing for pilot visibility in certain types of
aircraft are becoming increasingly perplexing. These difficulties
are in many respects similar to those herein described with respect
to boats and, in the interests of brevity, need not be set forth
herein in repetitious detail. It suffices to say that, for example,
the construction of the nose sections of certain aircraft is such
that elaborate and extremely expensive solutions have heretofore
been advanced. One such solution involves hinging the entire nose
section of a particular aircraft to provide pilot visibility from
the cockpit during certain critical operations such as those
involved in take-offs and landings.
This invention is useful to obviate the difficulties outlined
above. The chair and control panel or console provided for the
aviator would be contained within a preferably cylindrical
enclosure for the pilot's station, which enclosure would be either
of transparent material or provided with adequate window structure
for the pilot's vision which would be desired.
The enclosure, operably associated with a chair mechanism such as
that described herein especially with respect to its use for a
boat, would be elevatable through a suitable aperture in the hull
of the aircraft so that the pilot and his control console in the
enclosure could be elevated to a position exteriorally of the main
fuselage of the aircraft to a position affording the necessary
visibility.
The movable enclosure for the pilot's station would logically be
associated with the aircraft's cabin pressurizing equipment so that
the pilot's station would remain at the desired pressure even when
extended in the enclosure for purposes of enhanced visibility.
Appropriate seals between the enclosure and the aircraft hull would
be provided for maintenance of this pressure condition yet permit
extension and retraction of the pilot's station.
Manifestly, comparable structure incorporating the principles of
this invention may also be provided for submarine use. The
extendable enclosure for the pilot's seat and console would be
sealed against ingress of water and would provide protection
against the forces of the water. The extension for affording
enhanced visibility, either in the case of the aircraft or
submarine could be in any direction with respect to the vessel
hull.
As will be readily apparent to those skilled in the art, many
variations of the lifting mechanism 30 are possible, including
mechanically equivalent systems which operate with air
pressure.
