Definitions

  • the present invention relates to a shock absorbing mounting system for high speed watercraft, which isolates the watercraft operator against high impact shock loads.
  • the traditional solution to this problem is for the operator to wear some form of inflated cushion about his waist, and to stand with his knees bent while leaning against a wall of the cockpit while operating the boat. In this manner, vertical shocks are absorbed by the bending knees and lateral shocks are absorbed by the waist cushion.
  • shock loads can be difficult to manage for even a short period of time with this prior art technology.
  • Other types of watercraft are also subject to rough operating conditions, such that operation can only be tolerated for short periods of time unless effective shock isolation can be provided.
  • This invention relates to a shock absorbing seat mount of the type comprising a base, a seat mounting platform, a linkage interconnecting the base and the seat mounting platform and providing relative movement of the seat mounting platform with respect to the base along a line of motion between upper and lower positions, means for resiliently biasing the seat mounting platform to the upper position, and means for damping movement of the seat mounting platform along the line of motion.
  • means are provided for mounting the base to a high speed watercraft, wherein the base is oriented such that, with the watercraft floating in a stable, rest position, the line of motion at the upper position defines a first angle with respect to a horizontal line, and this first angle is within the range of 30- 70°.
  • Figure 1 is a perspective view illustrating a preferred embodiment of the mounting system of the invention
  • Figure 2 is a top view of the embodiment of Figure 1;
  • Figure 3 is a side elevation view in partial cutaway taken generally along line 3-3 of Figure 2;
  • Figure 4 is a side elevation view in partial cutaway illustrating the overall combination of a high speed water craft and the mounting system of Figures 1- 3;
  • Figure 5 is a schematic of the damper of the system of Figures 1-3.
  • the illustrated i embodiment comprises a base 12 for attachment to a frame or body of a high speed watercraft.
  • a platform 14 is positioned above the base 12 and connected thereto by a movable linkage and spring system that allows the platform 14 to move at an angle toward and away from the base 12 as a result of shock loads applied thereto.
  • the platform 14 is designed to mount an operator or passenger seat for the watercraft, preferably of the type in which the occupant is strapped into the seat.
  • the platform 14 is designed to move forward and down toward the base 12 during the shock damping movement thereof.
  • the platform 14 is supported in its position above the base 12 by a pair of parallel link members 16, 18, each pivoted at a respective end thereof to the base 12 and the platform 14. These link members 16, 18 extend at an angle to the vertical of about forty degrees under normal conditions.
  • a spring and shock absorber assembly comprises a coil spring 20 surrounding a shock absorber having a cylinder 22 and rod 24. The spring and shock absorber assembly extends at a cross angle to the two link members 16, 18, and is connected to the base 12 at the forward end thereof and to the platform 14 at the rear end thereof.
  • the spring and shock absorber assembly is connected with the end of the cylinder 22 secured to the platform 14 and the end of the rod 24 secured to the base 12.
  • the cylinder 22 is pivoted at pin 26 to a bracket 28 on a cross member 30 of the platform 14.
  • the rod 24 is pivoted at a pin 32 to a bracket 34 on a cross member 36 of the base 12.
  • the spring 20 is compressed between a radial shoulder 38 on the cylinder 22 and a shoulder 40 on the rod 24 for normally biasing the platform 14 to its uppermost position, as shown in the drawings.
  • the shock absorber cylinder 22 ( Figure 5) , illustrated as double acting, is connected to an external fluid reservoir 42, which contains a damping oil under pressurized nitrogen gas.
  • This connection is through an adjustable valve means 44 and high pressure lines 46 and 47 so that the resistance of the damper may be selectively adjusted to the load conditions.
  • the valve means is preferably adjusted to sustain on the order of a 2 G load before movement.
  • Both the base 12 and the platform 14 are preferably constructed of lightweight, open frames and of a suitable material, such as aluminum or stainless steel. Both are preferably constructed of a heavy gauge sheet metal and may be formed by a combination of stamping, welding and the like. Both the base 12 and the platform 14 are generally rectangular in plan form and are generally triangular in configuration in side elevation view.
  • the base 12 may be constructed and formed of a plurality of panels, including a pair of generally triangular side panels 48, 50, a transverse forward panel 52 having a somewhat channel shaped configuration, and a rear end and bottom panel 54 extending transversely across the rear end and partially along the bottom of the base 12.
  • the side and end panels 48, 50, 52, 54 have inwardly directed peripheral flanges along the top edges thereof for reinforcement and improved rigidity. Similar flanges extend inwardly along the lower or bottom edge of the end panels 52, 54.
  • This construction provides a rugged and strong base 12 which is light in weight. Large openings are formed in the panels to remove material and reduce weight without sacrificing strength.
  • the platform 14 may be constructed in a somewhat similar manner and is complementarily shaped relative to the base 12, with a pair of generally triangular side panels 56, 57 having a somewhat peaked base at the forward end of the platform, with a forward cross member 61 having a somewhat V-channel configuration, and a rear cross member 59 having a somewhat box beam configuration extending between the side panels 56, 57 at the rear thereof.
  • the two link members 16, 18 are identically shaped and of a generally rectangular frame configuration oriented to lie in a plane angled to the base 12. Each is provided with an upper cross member 58 at the forward end thereof, connected by a pivot pin and journal 60 (only one side is shown) to the platform 14, and a similar lower cross member 62 connected to the base 12 by a journal 64.
  • the upper and lower cross members 58, 62 are connected by laterally spaced side members 66, 68 extending between the upper and lower members 58, 62.
  • These members 58, 62, 66, 68 form a generally rectangular open frame construction providing high lateral strength and stability to the overall structure.
  • the spring and shock absorber assembly is pivotally connected to the forward cross member 36 of the base 12, and to the rearward cross member 30 of the platform 14.
  • the spring and shock absorber assembly supplied by White Brothers as Model WP 3614/BS has been found suitable.
  • the reservoir 42 may be secured to a bracket 72 by clamps 70, and the bracket 72 may be secured to the rear of the platform 14.
  • the mounting system of Figures 1-3 is illustrated in combination with a high speed watercraft, designated generally by the numeral 74.
  • the watercraft includes a hull 76 powered by a suitable engine 78.
  • An operator's seat 80 is rigidly secured to the platform 14, and the frame 12 is rigidly attached to a suitable frame member 82 of the hull 76.
  • the predominant direction of shock loads on the hull 76 will be along a line at an angle to a horizontal line along the longitudinal axis of the hull.
  • the predominant direction of the shock loads may vary with speed of the craft and also with the degree of stabilization of the craft.
  • a stabilized hull as in my aforementioned application, which is incorporated herein by reference as though fully set forth, would have a shallow angle on the order of about thirty degrees or less, as shown at 86 in Figure 4.
  • the platform 14 and the seat 80 move along a line of motion as the spring 20 is compressed by the mass of an operator when shock loads of the type described above are applied to the hull 76.
  • This line of motion is arcuate in this embodiment, and it has been oriented to isolate the operator from these shock loads to the greatest extent possible.
  • the line of motion of the platform 14 is oriented as shown at 84 at an angle of 30°-70° (preferably about 50°) with respect to the horizontal (with the hull 76 floating in a stable position at rest) .
  • the platform 14, seat 80 and operator will move downwardly and forwardly in response to shock loads applied to the hull during high speed planing. Because there is a substantial vertical component to this line of motion, the operator does not move excessively toward and away from the instrument panel. Because there is a substantial horizontal component, the line of motion is more nearly aligned with the line 86 of the shock load.
  • the cylinder 22 extends generally transverse to the link members 16, 18 and parallel to the line of motion when the platform 14 is in the upper position as shown in Figure 4.
  • the mounting system described above is designed to isolate an occupant of the seat 80 from shock loads applied to the hull 76.
  • the occupant of the watercraft is strapped in the seat 80, and the shock loads imposed by the rough and sudden movement of the watercraft are absorbed to a great extent in the movement of the platform 14 with respect to the base 12.
