BRIEF DESCRIPTION OF THE DRAWINGS

The present invention will be more fully and completely understood from a reading of the description of the preferred embodiment in conjunction with the drawings, in which:

FIG. 1 is a side section view of the upper portion of an outboard motor;

FIG. 2 is an exploded view of a removable cowl and a stationary cowl structure;

FIG. 3 is a section view showing the cam and cam follower portions of the present invention; and

FIG. 4 is a section view showing the cowl latching system of the present invention during a disengagement maneuver.

DESCRIPTION OF THE PREFERRED EMBODIMENT

Throughout the description of the preferred embodiment of the present invention, like components will be identified by like reference numerals.

FIG. 1 is a side section view of an outboard motor 10. The driveshaft housing, gear case, and propeller of the outboard motor 10 are not shown in FIG. 1, but those skilled in the art are familiar with the position of these components which are supported below the adaptor plate 14 of the outboard motor 10. A removable cowl 16 is shown in FIG. 1 attached to a stationary cowl structure 18.

Those skilled in the art of outboard motors are familiar with the fact that the removable cowl 16 is sometimes referred to as the upper cowl and the stationary cowl 18 is sometimes referred to as the lower cowl. The cowl latching system of the present invention is shown in FIG. 1 and identified by reference numeral 20. The structure of the individual components of the cowl latching system 20 will be described in greater detail below. In addition, a manually operable latch structure 24 is located at the rear portion of the outboard motor 10. The cowl latching system 20 is located at the front portion of the outboard motor.

FIG. 2 is a section view of the removable cowl 16 spaced apart from and above the stationary cowl 18. When the removable cowl 16 is being attached to the stationary cowl 18, it is moved in a vertically downward direction into contact with the stationary cowl 18. This represents one of the advantages of the present invention. By simply moving the removable cowl 16 in a generally vertical direction toward the stationary cowl 18, the components of the cowl latching system 20 cooperate with each other to allow the cowl latching system 20 to engage and retain the front portion of the removable cowl 16 in an engagement with the portion of the cowl latching system 20 attached to the stationary cowl structure 18.

The cowl latching system 20 of the present invention comprises a cam portion 30 and a cam follower portion 40. The cam portion 30 is attached to the stationary cowl structure 18 of the outboard motor. The cam follower portion 40 of the latching system 20 comprises a base 42, an arm 44 which is rotatably attached to the base 42, and a resilient member 46 which is configured to urge the arm 44 into a locking position. The locking position is the position of the arm 44 shown in FIG. 2. The base 42 is attached to the removable cowl 16 of the outboard motor 10. The arm 44 of the cam follower portion 40 is movable away from the locking position shown in FIG. 2 in response to the removable cowl 16 being moved in a generally vertical direction toward the stationary cowl portion 18. This generally vertical direction is a downward direction in FIG. 2 which moves the removable cowl 16 downwardly and into contact with the stationary cowl structure 18.

The cam portion 30 is movable out of the locking engagement with the arm 44 of the cam follower portion 40 in response to the removable cowl 16 being rotated relative to the stationary cowl structure 18 about a generally horizontal axis in a first direction as will be described in greater detail below in conjunction with FIG. 4. As illustrated in FIG. 1, a manually operable latch structure 24 is attachable to the rear portion of the stationary cowl structure 18 and the removable cowl structure 16. However, it should be understood that various different types of manually operable latch structure 24 can be used in conjunction with a preferred embodiment of the present invention and, furthermore, that the present invention is not limited to the use of any particular type of manually operable latched structure. The cowl latching system of the present invention operates in conjunction with the manually operable latch structure 24 and, in a particularly preferred embodiment, both of these structures cooperate with each other to retain the movable cowl 16 in attachment with the stationary cowl structure 18.

FIG. 3 is a section view of the cowl latching system 20 of a preferred embodiment of the present invention. In FIG. 3, the arm 44 is shown in its locking position with respect to the cam portion 30. In a particularly preferred embodiment of the present invention, the cam portion 30 is formed as an integral part of the stationary cowl structure 18, but in alternative embodiments it can be a separate component that is attached to the stationary cowl structure 18.

With continued reference to FIG. 3, the cam portion 30 comprises a first cam surface 32 and the arm 44 of the cam follower portion 40 comprises a first cam follower surface 47. The first cam surface 32 is movable in contact with the first cam follower surface 47 in response to the removable cowl 16 being moved in the generally vertical downward direction illustrated in FIG. 2 toward the stationary cowl portion 18. In other words, the first cam follower surface 47 moves into contact with the first cam surface 32 as the removable cowl 16 is lowered toward the stationary cowl structure 18 as shown in FIG. 2. This contact, which can be a sliding contact, causes the arm 44 to rotate in a counterclockwise direction about the axis identified by reference numeral 50 in FIG. 3. This moves the arm 44 into a non-locking position and permits the cam portion 30 to move upward relative to the arm 44 and achieve the locking position shown in FIG. 3 when the spring 46 urges the arm 44 in a clockwise direction subsequent to this completed movement of the removable cowl 16 in its downward direction into contact with the stationary cowl structure 18.

With continued reference to FIG. 3, the cam portion 30 also comprises a second cam surface 36. The arm 44 of the cam follower portion 40 comprises a second cam follower surface 49. The second cam surface 36 is movable in contact with the second cam follower surface 49 in response to the removable cowl 16 being rotated relative to the stationary cowl structure 18 of the outboard motor 10 about the generally horizontal axis in a second direction. The second direction is opposite to the first direction and, in FIGS. 2 and 3, the first direction is a clockwise rotation of the removable cowl 16 relative to the stationary cowl structure 18 while the second direction is a counterclockwise direction of rotation of the removable cowl 16 relative to the stationary cowl structure 18. The contact between the second cam surface 36 and the second cam follower surface 49 can be a sliding contact. As described above, the spring 46 serves as a resilient member that continually urges the arm 44 in a clockwise direction about axis 50.

With continued reference to FIG. 3, the cam portion 30 comprises a first locking surface 39 and the cam follower portion 40 comprises a second locking surface 48. The first and second locking surfaces, 39 and 48, are configured to retain the arm 44 in the locking position shown in FIG. 3 and, as a result, prevent the removal of the removable cowl 16 from the stationary cowl structure 18 when the arm 44 is in this locking position. The second locking surface 48 is movable away from the first locking surface 39 in response to the removable cowl 16 being rotated, in a counterclockwise direction in FIG. 3, relative to the stationary cowl structure 18 of the outboard motor 10 about the generally horizontal axis. As described above, this counterclockwise rotation of the removable cowl 16 is a rotation in the first direction. As a result, the second cam follower surface 49 moves against the second cam surface 36 to urge the arm 44 to rotate about its axis 50 in a counterclockwise direction so that the second locking surface 48 moves away from the first locking surface 39 and the arm 44 is urged into a non-locking position relative to the cam portion 30. This allows the operator to remove the removable cowl 16 from the stationary cowl structure 18.

FIG. 4 is a section view of the cowl latching system 20 as the removable cowl 16 is rotated relative to the stationary cowl structure 18. It should be understood that prior to the movement represented in FIG. 4, the manually operable latch structure 24, described in conjunction with FIG. 1, is first released by the operator. This permits the removable cowl 16 to rotate in the direction of arrow CCW in FIG. 4. This allows the second cam surface 36 to provide a force against the second cam follower surface 49 for the purpose of urging the counter clockwise rotation of the arm 44 about axis 50 against the urging of spring 46. As described above, this results in the second locking surface 48 moving away from the first locking surface 39 as represented by the directional arrow A in FIG. 4.

With reference to FIGS. 1–4, the advantages of the present invention can be seen. One advantage of the present invention is that it allows the operator to attach the removable cowl 16 to the stationary cowl structure 18 by moving the removable cowl 16 in a generally vertical direction downwardly, as illustrated in FIG. 2, toward the stationary cowl structure 18. In other words, the operator does not have to manipulate the removable cowl 16 such that one component of the latching structure is inserted into or becomes perfectly aligned with a receiving portion of that latching structure. Instead, a downward movement causes the first cam follower surface 47 to move into actuating contact with the first cam surface 32. Continued downward movement of the arm 44 with the removable cowl 16 rotates the arm 44 about its axis 50 as the first cam follower surface 47 passes over the first cam surface 32. This moves the arm 44 into a non-locking position and permits further movement of the cam 30 into engagement with the cam follower 40. Eventually, as the removable cowl 16 is moved toward its final downward position in engagement with the stationary cowl structure 18, the spring 46 urges the arm 44 into the locking position shown in FIG. 3, wherein the second locking surface 48 moves into engagement with the first locking surface 39 of the cam 30, as illustrated in FIG. 3, to retain the removable cowl 16 in its position attached to the stationary cowl structure 18.

Another advantage of the present invention is that it also facilitates removal of the removable cowl 16 from the stationary cowl structure 18. After the manually operable latch 24 is loosened, the operator can rotate the removable cowl 16, in a counterclockwise direction in the figures to allow the second cam follower surface 49 to move against the second cam surface 36 which urges the arm 44 in a counterclockwise direction against the force of the spring 46. This movement of the arm 44 disengages the first and second locking surfaces, 39 and 48, and allows the removable cowl 16 to be lifted away from the stationary cowl portion 18. The present invention facilitates both the attachment and removal of the removable cowl 16 in relation to the stationary cowl structure 18. When the removable cowl 16 is relatively large, these advantages provided by the present invention become significant because they simplify both the attachment and removal of the removable cowl 16 from the stationary cowl structure 18 and simplify the alignment of these components with each other.

Although the present invention has been described with particular specificity and illustrated to show a particularly preferred embodiment, it should be understood that alternative embodiments are also within its scope.
