Description
114646~
BACKGROUND OF THE INVENTION
Aboard many yachts a sterring station, i.e. the pilot house area, is provided in a cabin also utilized underway and when docked or anchored as a lounge. When underway, the helmsman, cpatain, or skipper, needs an unobstructed forward view, necessi-tating on many yachts the need for an elevated chair. Such an elevated chair on sGme yachts is permanently mounted at the raised elevation. On other yachts, generally wi-th less cabin space, an empty helmsman chair is manually preset al-ternately at either -the elevated underway position~ or at the lower docked or anchored position, by the skipper before he sits down. Many types of these two position helmsman, captain, or skippers' chairs are available now and have been used in the past. However, no helmsman chairs are known by the applicant to be available, on which a helmsman, skipper, or captain, while remaining seated, may operate controls to move himself or herself from a lounge level directable position to and back down from one or more underway elevated positions.
In respect to shipboard and/or yacht mounting of equip-ment, such as tables, automatic leveling mechanisms have been provided as early as 1924, as set forth in United States Patent No. 1,490,904, wherein Clark Anders disclosed how to keep such equipment level, notwithstanding the tilting or pitching of the ship. However, apparently no person was concerned with the changing of elevation of a helmsman chair by a skipper, who could operate nearby controls, while remaining seated in the chair, and also controlling his or her directional position.
For other purposes, not aboard a boat, yacht, or ship, others have provided sea-ting which could be located at respective elevations. Frank W. Adsit, used screw jack mechanisms to raise and lower an opera chair as set forth in his United States Patent No. 1,282,164, issued in 1918. To mee-t the respec-tive sizes of persons, Fred Gorden in 1952 provided his chair as shown in United States Pa-tent No. 2,608,23 using a powered screw jack mechanism.
For barber and beauty -hops Howard F. Mewman in 1961, in his United States Patent No. 2,989,280, disclosed an adjustable height chair also using a power screw jack mechanism -to raise and lower the person having his or her hair groomed by a barber and/or hair dresser. A hydraulically adjustable height sea-t for vehicles is disclosed in Edward M. Greer's United Sta-tes Patent No. 3,436,048 issued in 1969. A hydraulic lif-t device with a seat attachment is set forth in John E. Nolan's United States Patent No. 3,256,036 of 1966. Also many other adjustable seating assemblies are indicated by Dean H. Hale's utility stool illustrated in his United States Patent No. 3,147,946, issued in 1964.
Although many earlier inventors were concerned with adiustable seating and elevation changing mechanisms and marine leveling mechanisms, there remained a need for a more versatile helmsman chair for a yacht. Especially, for such a chair which could be positioned for both underway and docked or anchored use by a helmsman, captain, or skipper, who while so seated, could raise and lower the helmsman chair, using convenient controls, and also change the direction of his or her facing while so sea-ted.
SUMMARY OF THE INVENTION
For many yachts, a helmsman chair is positioned for a skipper, pilot, captain, or helmsman, to be seated at a lower convenient height in a lounge or salon cabin, facing the interior in selected directions during dockside or anchor times, and to be seated at an elevated, higher, convenient, height, as a portion of the lounge or salon cabin becomes the pilot house, when the yacht is underway and forward clear vision is required, as the wheel is held and/or turned to keep or to redirect -the yacht on a selec-ted course. For such positioning of the helmsman chair, a powered scew jack supporting mechanism, is operated as the skipper, pilot, captain, or helsman, remains seated and operates conveniently located controls, and a swivel directional suppor-ting mechanism, included ther-ein, responds to his or her hand and/or arm -torque creating forces.

DESCRIPTION OF THE INVENTION
A versa-tile helmsman chair 10, as illustrated in use in Figures l and 2, is installed on a yacht 12 often in a cabin 14, or designated area, which serves bo-th as a pilo-t house 16 and a lounge 18 or salon. In Figure l the helmsman, captain, or skipper, has raised himself or herself -to an elevated position, adjacent to the wheel 20, and other throttle controls 22 for his or her unobstructed forward view, while the yacht 12 is underway. Ye-t when the yacht 12 i5 at dockside or at anchor, -the helmsman, cpatain, or skipper, lowers himself or herself to a posi-tion of normal seating height above the lounge deck 24, and rotates this versatile helmsman chair 10 to join into ac-tivities with other crew members, guests, and/or passengers, as illustrated in Figure 2.
An embodiment of this helmsman chair 10, is shown in Figure 3 in a raised underway position, indicating a deck mounting assembly 26 secured to the lounge deck 24. This same embodiment is also illustrated in Fi.gure 4 in a raised underway position, indicating many of the interrelated structural, mechanical and electrical components. When there is adequate space 28 below the lounge deck 24, an electrical motor 30, with its gear box 32 and drive shaft 34, are positioned in this space 28. The overall positioning of the entire helmsman chair 10 is undertaken by using a flanged mounting base 36, secured with fastener assemblies 38 to the lounge deck 24, which clamps in a selected place the outer sleeve 40 of the helmsman chair 10. The upper split champing end 42 of the base 36 is tightened upon rotation of the threaded clamp-ing arm 44 to securely grip the outer sleeve 40.
Another embodiment of this helmsman chair 10 is shown in part, in Figure 5, in a raised underway position, indicating an all above deck mounting assembly 50 secured to a lounge deck 24. The assembly 50 inc.ludes an outside base 52 secured by fastener assemblies 38 to the lounge deck 24; an integral inside base 54, with a central recess 56; an upright co umn 58 secured to the base 52; and a top cover 60 with a central recess 62 secured by fastener assemblies 64. The non-extendable portions 66 of the helmsman chair 10 are non-rotatably supported within this above deck mount-ing assembly 50.
Both embodiments of -the helmsman chair 10 include a seat swivel assembly moun-ting plate 70 secured -to the top of their extendable portions 72, as showrl in Figures 3 and 5. A seat 74, --L~_ having a swivel assembly 76 secured to seat bottom 78, is mounted on the extendable portions 72 of the helmsman chair 1.0, as the swivel assembly 76 is at-tached to the mounting plate 70, using fastener assemblies 80. Such swivel mounting of the seat 74 is utilized by a helmsman, captain, or skipper -to conveniently change his facing direction from forward, while underway, to other facings when the yacht 12 is at dockside or at anchor, and -the helmsman chair 10 is lowered to normal chair height above the lounge deck 24.
Both embodiments of the helmsman chair 10, include the interrelated non-extendable portions 66, and the extendable portions 72, of an overall screw jack assembly 86, as illustrated in Figures 4 and 6. This assembly 86, with little or no modification in respect to the installations shown in the two embodiments of Figures 4 and 5, is sold under the trade mark LECTRA JACK, number 41606, manufactured by Reese Products of Elkhart, Indiana, mounted end for end, from the original designed use of jacking -the tongues of trailers.
An outer sleeve 40 is added and non-rotatably mounted to the combined gear box 32 and electric motor 30 as especially shown in Figures 4 and 6 to strengthen and protect -the outer stationary tube or cylinder 90, which is also mounted to the combined gear box 32 and electric motor 30. This outer sleeve 40 could possibly not be used in the embodiment illustrated in Figure 5, because the above deck mounting assembly 50 serves both protective and strengthening functions. An inner movable tube or piston 92 slides down into the outer stationary tube or cylinder 90, as the helmsman chair 10 is lowered to chair height in the lounge 18, and slides upwardly partially out of the outer stationary tube or cylinder 90, as the helmsman chair 10 is raised to the elevated position, when the yacht 12 is underway. Relative rotation of these tubes gO, 32 is prevented, as the interior projection rib 94 on the outer stationary tube or cylinder 90 is axially guided in the exterior groove or guide 96 on the inner movable -tube or pis-ton 92.
The relative axial translation of the inner movable -tube 1~4~61 92 into and out of the outer sta-tionary tube 90, is caused as the rotative power of an electric motor 30, via a gear box 32, drive shaft 34, and coupling components 100, i.e. -transverse load pin 102, and transverse slotted receiver 104, is applied to the axial ro-ta-table jacking screw 106. As -this jacking screw 106 rotates, a nut 108, via a ball bearing screw assembly 110, translates upwardly or downwardly along the jacking screw 106, carrying -the inner movable tube 92, to which the nu-t 108 is non-rotatably secured. The seat 74 of the helmsman chair 10 is -therefore also translated upwardly or downwardly as the jacking screw 106 is rotated, via the swivel mounting of the seat as illustrated in Figure 4. The inner- movable tube 92 is the essential component of the extendable portions 72, and the outer tube 90 is an essential component of the non-extend-able portions 66 of the helmsman chair 10.
The ball bearings 112 used in the ball bearing screw assembly 110 very effectively reduce the frictional load as the captain, skipper, or helmsman, remains seated during the up and down operations of the helmsman chair 10. The end threads 116 on the jacking screw 106, receive a stop nut 118, which prevents the nut 108 from leaving the jacking screw 106.
The nut 108 is interfitted with the inner movable -tube or piston 92 by securing to the nut 108 a cylindrical adapter 122, having a circumferential groove 124~ which receives an inwardly projecting circular rib 126 formed on the inner movable tube or piston 92, as illustrated in Figure 6. Another cylindrical adapter 130 is secured to the outer stationary tube 90, having a circum-ferential groove 132, which receives an inwardly projecting circular rib 134 formed on the outer sta-tionary tube or cylinder 90. The adapte-r 130 is understood to serve holding, bearing, alignment, and/or shock absorbing functions. Set screws 136 are used to axially position components such as the gear box 32 to the inner stationary tube 90 and/or outer sleeve 40.
The electric motor 30 is con-trolled by operating a swi-tch-ing assembly 133 loca-ted in an armrest 140, of -the sea-t 74, which -through the electrical wires 142, 144, operates a switching assembly 146 at the electric mo-tor 3n. The electrical wires 142, 144, well insulated and secured, exte:nd in-ternally of the helmsman chair between the respective swi-tches 138 and 146.

DESCRIPTION OF THE INVENTION
A versa-tile helmsman chair 10, as illustrated in use in Figures l and 2, is installed on a yacht 12 often in a cabin 14, or designated area, which serves bo-th as a pilo-t house 16 and a lounge 18 or salon. In Figure l the helmsman, captain, or skipper, has raised himself or herself -to an elevated position, adjacent to the wheel 20, and other throttle controls 22 for his or her unobstructed forward view, while the yacht 12 is underway. Ye-t when the yacht 12 i5 at dockside or at anchor, -the helmsman, cpatain, or skipper, lowers himself or herself to a posi-tion of normal seating height above the lounge deck 24, and rotates this versatile helmsman chair 10 to join into ac-tivities with other crew members, guests, and/or passengers, as illustrated in Figure 2.
An embodiment of this helmsman chair 10, is shown in Figure 3 in a raised underway position, indicating a deck mounting assembly 26 secured to the lounge deck 24. This same embodiment is also illustrated in Fi.gure 4 in a raised underway position, indicating many of the interrelated structural, mechanical and electrical components. When there is adequate space 28 below the lounge deck 24, an electrical motor 30, with its gear box 32 and drive shaft 34, are positioned in this space 28. The overall positioning of the entire helmsman chair 10 is undertaken by using a flanged mounting base 36, secured with fastener assemblies 38 to the lounge deck 24, which clamps in a selected place the outer sleeve 40 of the helmsman chair 10. The upper split champing end 42 of the base 36 is tightened upon rotation of the threaded clamp-ing arm 44 to securely grip the outer sleeve 40.
Another embodiment of this helmsman chair 10 is shown in part, in Figure 5, in a raised underway position, indicating an all above deck mounting assembly 50 secured to a lounge deck 24. The assembly 50 inc.ludes an outside base 52 secured by fastener assemblies 38 to the lounge deck 24; an integral inside base 54, with a central recess 56; an upright co umn 58 secured to the base 52; and a top cover 60 with a central recess 62 secured by fastener assemblies 64. The non-extendable portions 66 of the helmsman chair 10 are non-rotatably supported within this above deck mount-ing assembly 50.
Both embodiments of -the helmsman chair 10 include a seat swivel assembly moun-ting plate 70 secured -to the top of their extendable portions 72, as showrl in Figures 3 and 5. A seat 74, --L~_ having a swivel assembly 76 secured to seat bottom 78, is mounted on the extendable portions 72 of the helmsman chair 1.0, as the swivel assembly 76 is at-tached to the mounting plate 70, using fastener assemblies 80. Such swivel mounting of the seat 74 is utilized by a helmsman, captain, or skipper -to conveniently change his facing direction from forward, while underway, to other facings when the yacht 12 is at dockside or at anchor, and -the helmsman chair 10 is lowered to normal chair height above the lounge deck 24.
Both embodiments of the helmsman chair 10, include the interrelated non-extendable portions 66, and the extendable portions 72, of an overall screw jack assembly 86, as illustrated in Figures 4 and 6. This assembly 86, with little or no modification in respect to the installations shown in the two embodiments of Figures 4 and 5, is sold under the trade mark LECTRA JACK, number 41606, manufactured by Reese Products of Elkhart, Indiana, mounted end for end, from the original designed use of jacking -the tongues of trailers.
An outer sleeve 40 is added and non-rotatably mounted to the combined gear box 32 and electric motor 30 as especially shown in Figures 4 and 6 to strengthen and protect -the outer stationary tube or cylinder 90, which is also mounted to the combined gear box 32 and electric motor 30. This outer sleeve 40 could possibly not be used in the embodiment illustrated in Figure 5, because the above deck mounting assembly 50 serves both protective and strengthening functions. An inner movable tube or piston 92 slides down into the outer stationary tube or cylinder 90, as the helmsman chair 10 is lowered to chair height in the lounge 18, and slides upwardly partially out of the outer stationary tube or cylinder 90, as the helmsman chair 10 is raised to the elevated position, when the yacht 12 is underway. Relative rotation of these tubes gO, 32 is prevented, as the interior projection rib 94 on the outer stationary tube or cylinder 90 is axially guided in the exterior groove or guide 96 on the inner movable -tube or pis-ton 92.
The relative axial translation of the inner movable -tube 1~4~61 92 into and out of the outer sta-tionary tube 90, is caused as the rotative power of an electric motor 30, via a gear box 32, drive shaft 34, and coupling components 100, i.e. -transverse load pin 102, and transverse slotted receiver 104, is applied to the axial ro-ta-table jacking screw 106. As -this jacking screw 106 rotates, a nut 108, via a ball bearing screw assembly 110, translates upwardly or downwardly along the jacking screw 106, carrying -the inner movable tube 92, to which the nu-t 108 is non-rotatably secured. The seat 74 of the helmsman chair 10 is -therefore also translated upwardly or downwardly as the jacking screw 106 is rotated, via the swivel mounting of the seat as illustrated in Figure 4. The inner- movable tube 92 is the essential component of the extendable portions 72, and the outer tube 90 is an essential component of the non-extend-able portions 66 of the helmsman chair 10.
The ball bearings 112 used in the ball bearing screw assembly 110 very effectively reduce the frictional load as the captain, skipper, or helmsman, remains seated during the up and down operations of the helmsman chair 10. The end threads 116 on the jacking screw 106, receive a stop nut 118, which prevents the nut 108 from leaving the jacking screw 106.
The nut 108 is interfitted with the inner movable -tube or piston 92 by securing to the nut 108 a cylindrical adapter 122, having a circumferential groove 124~ which receives an inwardly projecting circular rib 126 formed on the inner movable tube or piston 92, as illustrated in Figure 6. Another cylindrical adapter 130 is secured to the outer stationary tube 90, having a circum-ferential groove 132, which receives an inwardly projecting circular rib 134 formed on the outer sta-tionary tube or cylinder 90. The adapte-r 130 is understood to serve holding, bearing, alignment, and/or shock absorbing functions. Set screws 136 are used to axially position components such as the gear box 32 to the inner stationary tube 90 and/or outer sleeve 40.
The electric motor 30 is con-trolled by operating a swi-tch-ing assembly 133 loca-ted in an armrest 140, of -the sea-t 74, which -through the electrical wires 142, 144, operates a switching assembly 146 at the electric mo-tor 3n. The electrical wires 142, 144, well insulated and secured, exte:nd in-ternally of the helmsman chair between the respective swi-tches 138 and 146.
