Description
- The present invention relates to a marine vehicle, and in particular to mechanical isolation of a pilot house or other cabin structure from a hull portion of a marine vehicle.
- It is well known that the cabin, cockpit and pilot house of typical marine vehicles, i.e., pleasure boats, are rigidly fixed to the boat hull. Accordingly, particularly in planing hull boats, riders in the boat are constantly bounced and jarred during high-speed travel over rough or choppy water. As a result of this bouncing and jarring, the ride is uncomfortable, and manual control of the boat's speed and heading may be degraded.
- The present invention overcomes limitations of the prior art by providing a boat having a hull, a passenger compartment structure that is separate from the hull, and one or more suspension elements suspending the passenger compartment structure relative to the hull.
- According to one aspect of the invention, the one or more suspension elements provide means for isolating the passenger compartment from shocks, vibrations and sounds experienced by the hull.
- According to one aspect of the invention, the means for isolating the passenger compartment from shocks, vibrations and sounds experienced by the hull include the one or more suspension elements formed as blocks of resiliently compressible material.
- According to another aspect of the invention, the means for isolating the passenger compartment from shocks, vibrations and sounds experienced by the hull include a plurality of the suspension elements formed of a combination compression spring and hydraulic vibration damper.
- According to another aspect of the invention, the hull further includes twin hulls configured as a catamaran, and a deck plate is provided as a generally planar plate spanning the twin hulls.
- According to another aspect of the invention, the one or more suspension elements are a plurality of the suspension elements arranged between the passenger compartment structure and the deck plate.
- According to another aspect of the invention, the boat includes an extension limiter capable of limiting separation of the passenger compartment structure relative to the hull.
- According to still other aspects of the invention, a method is provided for forming the boat of the invention having the means for isolating the passenger compartment from shocks, vibrations and sounds experienced by the hull.
- Other aspects of the invention are detailed herein.
- The foregoing aspects and many of the attendant advantages of this invention will become more readily appreciated as the same becomes better understood by reference to the following detailed description, when taken in conjunction with the accompanying drawings, wherein:

FIG. 1 illustrates the present invention by example and without limitation embodied as aboat 10 having a planinghull 12 with a separatepassenger compartment structure 14 such as any of a cockpit, pilot house or other cabin structure that is elastically suspended from the hull by a means of one or moreelastic suspension elements 16 therebetween, thesuspension elements 16 isolating thepassenger compartment 14 from shocks, vibrations and noise experienced by thehull 12. Planinghull 12 is optionally a single hull (shown in phantom) or double hull (shown in solid) commonly referred to as a catamaran.Passenger compartment 14 is constructed fully separate and independent fromhull 12 with afloor 18 and substantiallyupright walls 20 and may include a cover orroof structure 22 that is either permanently attached or detachable. Anoptional deck plate 24 is substantially rigidly connected to thehull 12, for example, by mechanical fasteners, by fiberglass webbing and resin, or by welding if theboat 10 is formed of a weldable material, such as aluminum or steel. Theoptional deck plate 24 may be substantially planar as in a plate spanning thetwin hulls 12 of a catamaran, or may be generally conformed to thehull 12. -
Passenger compartment 14 is spaced off thehull 12, ordeck plate 24 if present, of theboat 10 with one or more of thesuspension elements 16 interposed and coupled between thepassenger compartment 14 and thehull 12 or deck plate 24 (shown). Thesuspension elements 16 are optionally arranged between thepassenger compartment floor 18 and thehull 12 ordeck plate 24, ordeck plate 24 if present, in multiple positions selected to adequately support thepassenger compartment floor 18. -
FIG. 2 is a side cross-section view showingmultiple suspension elements 16 being arranged in different spaced apart positions along thepassenger compartment 14 between thefloor 18 andoptional deck plate 24. -
FIG. 3 is an end cross-section view showingmultiple suspension elements 16 being arranged in different spaced apart positions across thepassenger compartment 14 between thefloor 18 andoptional deck plate 24. Planinghull 12 is optionally a single hull (shown in a previous Figure) or a double hull with afirst hull 12 a rigidly suspended inside asecond hull 12 band may include Styrofoam® orother buoyancy filler 26 in between. -
FIG. 4 is a blown-up section view showing thesuspension elements 16 attached, by example and without limitation, usingadhesion bonds 28 orfasteners 30 which may be of either the threaded or unthreaded variety. Thesuspension elements 16 are, by example and without limitation, any of a variety of well-known elastic connector assemblies, such as vibration and shock isolators formed as pads or blocks of resiliently compressible material such as but not limited to rubber, neoprene or another resiliently compressible elastic material. Thesuspension elements 16 are substantially solid but may be configured with chambers or “pockets” 32 which are optionally air or gas-filled chambers. The pad or block of resiliently compressible material forming the one ormore suspension elements 16 is optionally provided as a combination of a few large pads extending under substantially theentire compartment floor 18, although the large pads may be pierced with one or a large number of holes there through so that the largepad suspension elements 16 resemble Swiss cheese. Alternatively, thesuspension elements 16 is optionally provided as a single large pad extending under substantially theentire compartment floor 18, although the single large pad also may be pierced with one or a large number of holes there through as discussed above for the combination of a few largepad suspension elements 16. - During travel of the
boat 10, up and down oscillatory movement of thehull 12 and attacheddeck plate 24, if present, will occur and this movement is transmitted to thepassenger compartment floor 18 viasuspension elements 16. Anoptional extension limiter 34 is capable of limiting the maximum amount of separation or upward vertical travel which can occur in thepassenger compartment 14 away from thehull 12, or thedeck plate 24 if present. By example and without limitation, theextension limiter 34 is a threadedshank 36 which passes through thepassenger compartment floor 18 anddeck plate 24 and includes acapture mechanism 38 on either end, such as opposing nuts and washers. The extension limiter 34 optionally permits a limited degree of separation movement of thecompartment floor 18 relative to thedeck plate 24. For example, theextension limiter 34 optionally extends beyond thepassenger compartment floor 18 or deck plate 24 (shown) a selected amount that is, for example, calculated to protect thesuspension elements 16 from catastrophic failure in the event of an extreme separation of thepassenger compartment 14 and thehull 12, or thedeck plate 24 if present. Thecompartment floor 18 and thehull 12, or thedeck plate 24 if present, both optionally includereinforcements 40 such as extra plate thickness (shown) in the vicinity of theextension limiter 34 to protect against catastrophic failure and sudden separation of thepassenger compartment structure 14 from thehull 12, or thedeck plate 24 if present. -
FIG. 5 illustrates thesuspension elements 16 alternatively configured to include a gas or liquid filledbladder 42. When having either a gas or liquid filledbladder 42 or embodied as a compression spring and hydraulic damper, an increase or decrease of the spring rate of thesuspension elements 16 is effected by varying the pressure within the bladder or in conventional fashion. For example, a “Schrader”valve 44 interconnected by apipeline 46 to thesuspension elements 16 so as to provide access to the interior of thebladder 42 there within. By operating thisvalve 44 manually to expel air from thebladder 42, the spring rate or stiffness of thecorresponding suspension element 16 is decreased. Similarly, by application of a high pressure source of air to thevalve 44, the pressure within thebladder 42 can be increased to raise the spring rate or stiffness of thecorresponding suspension element 16. During travel of theboat 10, up and down oscillatory movement of thehull 12 and attacheddeck plate 24, if present, will occur and this movement is transmitted to thepassenger compartment floor 18 viasuspension elements 16. However, the movement is relatively dampened by the action of thesuspension elements 16 acting as a conventional shock absorber between thepassenger compartment floor 18 and thehull 12, or thedeck plate 24 if present, when a sudden variation occurs in elevation of thepassenger compartment 14 relative to thehull 12, or thedeck plate 24 if present. Relative bouncing upward and downward movements of thepassenger compartment 14 are thus effectively smoothed. - Here, the
optional extension limiter 34 includes aflexible cable 48 capable of limiting the maximum amount of separation or upward vertical travel which can occur in thepassenger compartment 14 away from thehull 12, or thedeck plate 24 if present. Thecable 48 is affixed to thehull 12, or thedeck plate 24 if present, and thepassenger compartment 14, for example, thepassenger compartment walls 20, and is arranged so as to be normally in a slack condition, but to be in a taut condition where excessive upward movement of thepassenger compartment 14 occurs relative to thehull 12, or thedeck plate 24 if present. -
FIG. 6 illustrates thesuspension elements 16 alternatively configured as a coil spring which is by example and without limitation either single-turn or double-turn coil spring. The coilspring suspension elements 16 are optionally welded or otherwise bonded to a surface of thepassenger compartment 14, for example thecompartment floor 18, as shown. The coilspring suspension elements 16 are also bonded to thehull 12, or thedeck plate 24 if present. Alternatively, the coilspring suspension elements 16 are secured in appropriatelyshaped receptacles 50 that are in turn coupled to thecompartment floor 18. Alternatively, the coilspring suspension elements 16 are secured in additionalshaped receptacles 50 that are in turn coupled to thehull 12, or thedeck plate 24 if present. The coilspring suspension elements 16 isolate thepassenger compartment 14 from shocks, vibrations and noise experienced by thehull 12. - Alternatively, as illustrated by example and without limitation in
FIG. 7 , one or more of coilspring suspension elements 16 are optionally supported at thedeck plate 24, if present, or thehull 12 bybrackets 58 or directly from thedeck plate 24 orhull 12, and may be supported at thepassenger compartment 14 byadditional brackets 60 on thecompartment walls 20. - Optionally, the
optional extension limiter 34 is provided for limiting the maximum amount of separation or upward vertical travel which can occur in thepassenger compartment 14 away from thehull 12, or thedeck plate 24 if present. By example and without limitation, theextension limiter 34 includes the threadedshank 36 which passes through thepassenger compartment floor 18 anddeck plate 24, if present, and includes thecapture mechanisms 38 on either end, such as opposing nuts and washers. Theextension limiter 34 optionally permits a limited degree of separation movement of thecompartment floor 18 relative to thedeck plate 24. For example, theextension limiter 34 optionally extends beyond thepassenger compartment floor 18 or deck plate 24 (shown) a selected amount that is, for example, calculated to protect thesuspension elements 16 from catastrophic failure or excessive dislocation in the event of an extreme separation of thepassenger compartment 14 and thehull 12, or thedeck plate 24 if present. Thecompartment floor 18 and thehull 12, or thedeck plate 24 if present, both optionally includereinforcements 40 such as extra plate thickness (shown) in the vicinity of theextension limiter 34 to protect against catastrophic failure and sudden separation of thepassenger compartment structure 14 from thehull 12, or thedeck plate 24 if present. -
FIG. 7 is an end cross-section view showingmultiple suspension elements 16 configured as conventional spring-and-dash pot shock absorbers arranged in different spaced apart positions across thepassenger compartment 14 between thefloor 18 and thehull 12 oroptional deck plate 24, if present. By example and without limitation, thesuspension elements 16 are any of a variety of well-known compression spring and hydraulic vibration damper operating in the normal fashion of a vehicle shock absorber. By example and without limitation, the shockabsorber suspension elements 16 includepush rod 52 engaging a pressurized gas-filledchamber 54 the whole being substantially surrounded by acompressed coil spring 56. The shockabsorber suspension elements 16 are optionally coupled to thedeck plate 24, if present, or thehull 12 as shown. By example and without limitation, the shockabsorber suspension elements 16 are optionally supported at thedeck plate 24, if present, or thehull 12 bybrackets 58 or directly from thedeck plate 24 orhull 12. As shown on left, the shockabsorber suspension elements 16 are optionally supported at thepassenger compartment 14 byadditional brackets 60 on thecompartment walls 20. As shown on left, the shockabsorber suspension elements 16 are alternatively optionally supported at thepassenger compartment floor 18 which optionally includes thereinforcements 40 such as extra plate thickness (shown) in the vicinity of thesuspension elements 16. -
FIG. 8 is a blown-up section view showing the shockabsorber suspension elements 16 attached, by example and without limitation, between thepassenger compartment floor 18 and thehull 12. As illustrated here, thecompartment floor 18 includes thereinforcement 40 where the shockabsorber suspension element 16 is attached, and thehull 12 is protected by anotherreinforcement 62 on which the shockabsorber suspension element 16 is supported. - While the preferred embodiment of the invention has been illustrated and described, it will be appreciated that various changes can be made therein without departing from the spirit and scope of the invention. For example, materials may be substituted for the different components of the boat and suspension elements of the invention without departing from the spirit and scope of the invention.
