Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an outboard motor for a boat, and more particularly to a support device for a small outboard motor.

Low power electric outboard motors are used for fishing, especially when it is desirable to operate the boat slowly and quietly.

These small outboard motors are mounted on ships in such a way that they can be lifted out of the water and held in a retracted position within the ship while the ship is being propelled or transported at normal speeds by the higher horsepower outboard motors.

When in the reverse position, the entire outboard motor, including the propeller, is preferably positioned inboard.

In order to minimize the effort required to move the outboard motor between the operating position and the stowed position, it is desirable that the outboard motor support system be arranged so that the outboard motor swings in as small an arc as possible.

Examples of prior art outboard motor support systems are described in the following US patent specifications: US Pat.

It includes a pair of laterally spaced parallel elongate members 50 (only one shown) pivotally connected to support bracket 24 by an extending pin 53.

A tension rope 54 is connected to the support member 28 for moving the propulsion unit 12 between the operating position and the stowed position.

Link. While the units 37, 38 are moving between the working and storage positions, the lower sleeve 30 moves in a generally arcuate path bounded by the pivot radius of the link 44 and the upper sleeve 32 follows the pivot radius of the arm 50. It moves along a nearly arc-shaped path regulated by.

Each of the ears 40 of the support bracket is provided with a link.
In order to limit the arcuate movement of the unit 37 in a counterclockwise direction when viewed from FIGS. 1 and 2, an arcuate suppression surface 55 is provided, with which each link 44 can engage. , thus acting as a stopper for these.

The pressing surface 55 is arranged to assist in positioning the tubular member 18 in a generally horizontal position when the link units 37, 38 are in the stowed position.

When the outboard link 37 is in the operative position, the link 44 is provided at the outboard end of the support bracket 24 to allow the outboard link unit 37 to move in an arc in a clockwise direction as viewed in FIGS. 1 and 2. It abuts against a stopper member 56 that limits the movement of the object.

In a preferred embodiment of the invention, the vertical position of the stop member 56 relative to the support bracket 24 is selectively adjusted to facilitate adjustment of the tubular member 18 relative to the vertical when the propulsion unit 12 is in the active position, i.e., trimming the propeller. A regulating device is provided.

Although a variety of arrangements are possible, the particular configuration illustrated includes a pair of laterally spaced apart support bracket base members 39 extending upwardly from both ends of the stop member 56. The guide slots 58 are slidably mounted in respective guide slots 58 provided in the flange 60 .

The stopper member 56 is supported on the base member 39 by a barb or stud 62 which is screwed therein and presses against the base member 39.

The vertical position of stop member 56 can be adjusted by turning scud 62 clockwise or counterclockwise.

Apparatus is provided for releasably and selectively latching the outboard linkage unit 37 between a working position and a stowed position.

Although a variety of arrangements are possible, in the particular construction shown, the device is slidably mounted in guideways 66 in the base members 39 of the support bracket and hook portions 72 . The latching member 64 includes a pair of spaced upright latching elements 68, 70 having a latching element 68,70.

Hook portion 72. 74 engages pins 76 extending laterally between the links 44 to releasably hold the outboard link unit 37 in the operative and stowed positions, respectively.

Hook portions 72, 74 may be provided with cam edges 78, 80, respectively, to facilitate initial latching engagement of pin 74.

A device is provided for biasing the latch elements 68,70 in a direction that causes the respective hook portions 72,74 to engage the pins 76.

Although other arrangements are possible, in the particular construction shown, the device is connected to the inboard end of the latch member 64 and the base member 3.
9 and presses the latch member 64 to the right as viewed from FIGS. 1 to 3.

A suitable device, such as a tension rope 84 attached to latching element 70, moves latching member 64 against the action of spring 82 (i.e., moving latching member 64 to the left as viewed in FIGS. 1 and 2). Latch element 68, γ0
is provided to release the pin 76 from the pin 76.

Thus, when the propulsion unit 12 is in the active position, the hook portion 12 of the latch element 68 is engaged with the pin 76.

To move the propulsion unit 12 from the operating position to the stowed position, the pull rope 84 is first pulled rearward to release the latch element 68 from the pin 76 and then the pull rope 54 is pulled upward to swing the propulsion unit 12 toward the stowed position. .

After the upper sleeve 32 has passed the apex of its arcuate path, it is provided with a lock to control the downward movement of the propulsion unit 12 to the stowed position and to facilitate passage of the pin 76 through the hook portion 74 of the latching element 70. A tension rope 54 can be used to hold the cable.

Sleeves 30 , 32 are slidably attached to the tubular member 18 so that the upper sleeve 32 is attached to the propulsion unit 12 .
slides freely over the tubular member 18 during the initial movement toward the stowed position (during which time the support member 38 remains engaged with the lower sleeve 30 due to the weight of the propulsion unit).

While the propulsion unit 12 continues to move towards the stowed position, the upper sleeve 32 eventually engages the ears 36 and the tubular member 18 is then forced into the lower sleeve 30 by the tension exerted by the upper sleeve 32. The relative axial movement eventually causes the lower sleeve 30 to engage the ear.

Thus, by the time the propulsion unit 12 reaches the stowed position (FIG. 1), the lower unit 14 is automatically retracted to an inboard position.

Referring to FIGS. 1 and 2, the arrangement of link 44, pressure surface 55, and arm 50 allows the γ-arm 50 to be A dog arc (for example, 120°) of the link 44
For example, it can be seen that they are arranged to move over a range of 155°.

Due to this arrangement, when the propulsion unit 12 is in the storage position, the tubular member 18 is in a substantially horizontal position.

Also, because the radius of the arcuate path through which the lower end of the propulsion unit 12 moves is relatively short, the effort required to move the propulsion unit 12 between the operating and storage positions is much lower than in many prior art supports of this type. It is less expensive than the labor required for the equipment.

During the return movement of the propulsion unit 12 from the storage position to the working position, the weight of the propulsion unit, the tubular member 18 and the sleeve 3
The combined effect of the relative axial movement between 0.32 and 0.32 degrees causes the propulsion unit 12 to return to the working position in which the support member 28 engages the lower sleeve 30.
