9 Claims. (Cl. 114-153) This application is a continuation-in-part of application Ser. No. 416,276, filed Dec. 7, 1964, now abandoned.

This invention relates to an apparatus for steering a boat. More particularly, the invention relates to an apparatus for steering a boat equipped with an outboard motor by means of the attachment of the apparatus to the outboard motor.

Outboard motors, because they are adaptable to be quickly and easily attachable to many kinds and makes of boats, generally include various control mechanisms on the motor itself. The controls usually include means for starting the motor, means for controlling the speed of the motor, and means for pivoting the motor about a vertical axis when it is mounted on the boat so that the direction in which the motor is positioned in relation to this vertical axis will determine the direction of the movement of the boat.

Generally, the outboard motor includes the direction controlling or steering device in the form of a handgraspable bracket or lever. Thus, when using an outboard motor so equipped, the operator usually has one hand fully occupied in steering the boat. Having one hand fully occupied steering the boat is particularly disadvantageous for a solitary fisherman, particularly one who is engaged in trolling.

An object of this invention is therefore to provide a means for steering a boat by foot so that the operator may have both hands free.

Another object of this invention is to provide a footoperable steering device for outboard motors which does not include any structure attached tothe boat itself.

Still another object of this invention is to provide an apparatus for steering a boat which is easily attachable to a wide variety of outboard motors.

A special advantage of this invention is that it may be quickly and easily attached to an' outboard motor to provide a means for the operator to steer the boat by the movement of his foot, thus permitting his hands to be free. The invention comprises an adjustable device to permit its use with outboard motors of various geometry in relation to the boat with which the motor is used, that is, in addition to being adaptable to various motors, the device is adjustable in the horizontal and vertical directions so that the most appropriate and most eflicient use may be made of the device.

Further objects and advantages of the invention will become apparent from the following description and claims, and from the accompanying drawings in which:

FIGURE 1 is a perspective view of a device prepared according to this invention showing one means of attachment to an outboard motor.

FIGURE 2 is a perspective view of a modified device prepared according to this invention showing another means of attachment to an outboard motor.

FIGURE 3 is a front elevational view of one type of foot-engaging component of the device.

3,371,641 Patented Mar. 5, 1968 FIGURE 4 is a side elevational view of a foot-engaging component shown in FIGURE 3.

The foot-operable steering device of this invention comprises a bracket portion, adaptable to fit various outboard motors, a normally horizontal extensible arm attached by one end to the bracket, a normally downwardly depending extensible arm pivotally mounted at one end to the end of the horizontal arm furthermost from the bracket portion, and a foot-embracing stirrup detachably and swivelably mounted to the lower end of the downwardly depending arm. Thus, when the horizontal arm is secured to the bracket portion in a rigid position and the downwardly depending arm and stirrup are properly adjusted and positioned, the stirrup will be positioned slightly above the floor of the boat so that the operators foot may rest comfortably in the stirrup and movement of the operators foot in a horizontal direction will move the stirrup also in a horizontal direction radially around the outboard motor so that the steering lever or other guiding component of the outboard motor will move arcuately about a vertical axis through the outboard motor.

Referring now to the figures in detail, FIGURE 1 describes one form of foot-operable steering attachment prepared according to this invention in which the apparatus is positionable upon a type of outboard motor having a hand-graspable bracket which serves as a guiding component. In this form of the invention a motor bracket 10, which normally serves as a guiding component by which the motor can be swivelled about a vertical axis, is generally an integral part of the motor and serves as the means of attachment for the steering attachment. To this motor bracket is attached a motor mount bracket 12 detachably secured to the motor bracket by a bolt 14 held in place by a nut 16. Conventional quickly removable bolts and nuts may be used as, for example, a thumb screw may be used in place of bolt 14 and a wing nut in place of nut 16. Bracket 12 is shown in FIGURE 1 to be formed of a fiat plate-like member containing a series of adjustment holes 18. Preferably, a flat plate-like structure is used but suitable similar brackets employing, for example, tubular components may also be used. Detachably secured to bracket 12 is a horizontal extension arm 20 held in place on bracket 12 by a conventional means of attachment such as a nut and bolt. Horizontal extension arm 20 includes a number of adjustment holes 22 to provide means of lengthening the horizontal extension arm of the steering device and is designed to fit the particular outboard motor and boat with which the device is used. For most purposes, a single horizontal extension arm may be employed suitably, but this would not preclude the use of multiple horizontal extension arms, were it is necessary, such as in those instances where the horizontal adjustment is quite large and where it would be desirable to strengthen the horizontal portion of the apparatus by overlapping several extension arms. Detachably secured to horizontal extension arm 20 and extending longitudinally beyond that arm is horizontal pivot arm 24, preferably securable to arm 20 by conventional means such as a machine bolt and nut. It can be seen that in certain circumstances pivot arm 24 may be connected directly to bracket 12 without the necessity of using an extension arm 20. Pivot arm 24 preferably includes a flattened end section 26 describing a substantially vertical plane. End section 26 is flattened and substantially vertical so that horizontal motion of the downwardly depending components of the apparatus;

hereinafter described, will be efficiently transmitted to the horizontal arm to control movement of the outboard motor. Pivotally connected to end section 26 is a downwardly depending extensible arm. A flattened end section 28 of the downwardly depending arm is removably secured adjacent end section 26 with any conventional nut and bolt. In FIGURE 1, end section 28 is shown in a right angular plane with reference to the other portion of a vertical pivot arm 30 of which end section 28 is a part. In this arrangement of the apparatus, vertical pivot arm 30 is preferably arranged in a plane normal to the usual direction of movement of the vertically depending arm for the purpose of providing rigidity to the arm. Arm 30 includes a number of adjustment holes 32 to provide a means for lengthening or shortening the overall height of the apparatus. A vertical extension arm 34 is provided to serve a similar purpose to the horizontal extension arm as a means of adjustment. Arm 30 and extension arm 34 are connected by conventional means, preferably some form of quick-connecting devices, such as wing nuts. Removably secured to extension arm 34 and, if necessary, also attachable to arm 30 is a stirrup mounting bracket 36. Bracket 36 includes a number of adjustment holes 38 by means of which the length of the vertically depending arm may be further adjusted. If the particular method of attachment of the apparatus is such that the vertical distance from horizontal arm 24 to the floor of the boat is quite short, then extension arm 34 would become unnecessary and the vertical adjustment of the apparatus could be accomplished by the positioning of bracket 36 in relation to pivot arm 30. Swivelable movement of the foot engaging stirrup is provided for by the unique positioning of stirrup clip 42. Clip 42 is removably secured to mounting bracket 36 with an adjustable nut and bolt to permit movement in two different planes. For example, in FIG- URE 1 bracket 36 is seen to include a right angular portion 44 pivotally mounted adjacent a right angular portion 46 of stirrup clip 42. Right angular portions 44 and 46 are preferably mounted by means of an adjustable nut and bolt, such as a conventional machine bolt having two nuts mounted thereon in a manner that the second nut acts as a locking nut for the first to permit the two bracket portions to be loosely and adjustably mounted to each other. Similarly, stirrup clip 42 has a second right angular portion 48 similarly mounted between two band portions 50 of stirrup 40. Stirrup 40 includes a foot rest 52. Thus, in use, the operators foot fits through stirrup 40 and by the movement of his foot against band portions 50 and foot rest 52, the operator is able to move the stirrup swivelly with relation to the other parts of the downwardly depending arm and also horizontally with respect to the outboard motor. If desired, the adjustment with relation to each other of sections 26 and 28, 44 and 46, and 48 and 50 permit the operator to move the downwardly depending arm in the manner most comfortable for him. Preferably, the substantially horizontal portion of the apparatus has a certain amount of flexing ability so that when the operator has moved the device to a chosen position, he may exert a downward force against foot rest 52 so that the weight of his foot bears foot rest 52 against the bottom of the boat in a stable position.

FIGURE 2 discloses a slight modification of the apparatus in that the apparatus shown here is adapted to be received on a slightly different form of outboard motor. This modification includes a holding means formed from a U-bolt 54, removably secured by nuts 56 to plate 58 which in turn is removably secured to a horizontal extension arm 20.

FIGURE 3 discloses another type of swivel device which may be used in place of angular portions 44, 46, 48 and 50. In this modification, stirrup mounting bracket 36 is modified at its lower end to have a socket portion 60 which receives a ball portion 62 attached to a unitary band portion 64. FIGURE 4 shows the ball and socket swivel in side elevational view.

Preferably, the substantially horizontal extending arm member and the downwardly depending arm member are formed of plate-like members for ease of production, strength and flexibility. But these members may also be prepared of tubular telescopic components co-acting in a similar manner.
