Abstract
The present invention relates to a self-trimming oscillating system. This system comprises a wing like member (5) pivotally mounted on an elongated lever (3). It also comprises reciprocating connecting (49) means adapted to cause articulation of the elongated lever (3) on the one hand and to be rotatably associated with a crank means (45) on the other hand. Means (57) responsive to reciprocation of the connecting means causes oscillation of the wing (5) as the elongated lever (3) is articulated.
Claims
1. A self-trimming oscillating system adapted for use with a fluid, which comprises a base having a support member extending therefrom; an elongated lever having a first end and a second end, the first end being pivotally mounted to the support member; at least one wing like member pivotally mounted to the second end of said elongated lever and extending transversally thereto, in a manner to permit pivoting of the at least one wing like member relatively to the second end of the elongated lever and simultaneous oscillation of said at least one wing like member when said elongated lever is pivoted on the support member; crank means spaced-apart from the support member; reciprocating means connected to said elongated lever and cooperating with said crank means, whereby, upon rotation of the crank means, said elongated lever pivots about the first end mounted to the support member and, upon pivoting of the elongated lever, the crank means are rotated; and a link member having a first end and a second end, the first end cooperating with the reciprocating means and the second end being secured to a first pivot connection of a first joint, the first joint having a second pivot connection secured to the at least one wing-like member, whereby, upon actuating the reciprocating means, translation movements are imparted to the link member and pivoting movements are imparted to the wing like member and, upon pivoting the wing like member, translation movements are imparted to the link member providing actuation of the reciprocating means.
2. Self-trimming oscillating system according to claim 1, which comprises means causing oscillation of said wing like member in response to operation of said reciprocating means.
3. Self-trimming oscillating system according to claim 1 , which comprises an elevon articulately mounted on a rear edge of said wing like member, and means dictated by pivoting of said wing like member to produce a predetermined articulation of said elevon relative to said wing like member.
4. Self-trimming oscillating system according to any one of claims 1 to 3, wherein said base comprises rotatable means to permit orientation thereof so that a front edge of said wing like member directly faces an incoming flow of a fluid.
5. Self-trimming oscillating system according to claim 1 , wherein said fluid is water or air.
6. Self-trimming oscillating system according to claim 3 wherein said reciprocating means comprises a connecting rod.
7. Self-trimming oscillating system according to claim (6, which comprises a crank support mounted on said base, said crank means being rotatably and centrally mounted on said crank support and being keyed to a lower end of said connecting rod, said connecting rod having an upper end articulately mounted to said elongated lever at a location intermediate between the first and the second ends of said elongated lever, and a pulley operatively connected to said crank means to be engaged in rotation therewith.
8. Self-trimming oscillating system according to claim 3, which comprises a pivoting rod longitudinally extending through said wing like member; and a transverse slit formed in said wing like member, said slit extending from a front edge of said wing like member to a point intermediate between said
17 front edge and said read edge of said wing like member where said pivoting rod extends through said wing like member, said elongated lever and said second pivot connection of the first joint being associated with said pivoting rod for pivoting of said wing like member about the second end of the elongated lever.
9. Self-trimming oscillating system according to claim 3, which comprises a first articulation tab upwardly projecting at the second end of said elongated lever, a second articulation tab disposed on said elevon and aligned with said first articulation tab, and an activating lever having both end articulately connected respectively to said first and second articulation tabs so that when said wing like member pivots in one direction, said elevon pivots in the same direction.
10. Self-trimming oscillating system according to claim 6, which comprises means cooperating with said reciprocating means and said link member to adjust extent of pivoting of said wing like member.
11. Self-trimming oscillating system according to claim 6, wherein the support member comprises an upright holder fixedly mounted to said base and a second joint having a first pivot connection pivotally mounted to the upright holder and a second pivot connection, the first end of said link member being pivotally mounted to the second pivot connection of the second joint.
12. Self-trimming oscillating system according to claim 11 , comprising a first arm having a first end pivotally mounted to the second pivot connection of the second joint and a second end; a second arm having a first end articulately connected to the second end of said first arm, a second end, and a fixed pivot point allowing the second arm to pivot therearound, linking means having a first end articulately connected to said connecting rod and a second end articulately connected to the second end of the second arm,
18 whereby, upon rotation of the crank means, translation movements are imparted to the second end of the linking means, said translation movement of the second end of the linking means pivoting the second arm around the fixed pivot point, pivoting of the first end of the second arm imparting translation movements of the first arm and the link member and, upon translation movements of the link member, translation movements of the first arm, pivoting of the second arm, translation of the linking means, and rotation of the crank means are imparted.
13. Self-trimming oscillating system according to claim 11 , wherein the fixed pivot point is displaceable along the second arm for controlling the pivoting movement of the wing like member.
14. Self-trimming oscillating system according to claim 11 , wherein the second arm comprises a longitudinal sliding channel and the support member comprises an extension guide having a first end arranged to slide therealong and a second end arranged to slide along said longitudinal sliding channel so as to control angular displacement of said second arm and consequently the pivoting movement of the wing like member.
