FIELD OF THE INVENTIONThe present invention relates generally to the field of water craft. More specifically, the present invention relates to articulating tops for water craft.
BACKGROUNDBoats can be equipped with some form of sun shade apparatus or other enclosure such as a top, canopy or bimini. Some tops can be moved between a first, stowed, collapsed or trailering position and a second, extended or deployed position. Some tops are constructed out of tubular frames that articulate to at least two positions and, sometimes, a third, radar position. Some such tops can be manually articulated to a desired position, while others utilize mechanical aids such as hydraulics or electric motors to power the apparatus into the desired position(s).
Most tops are not intended for use in a deployed position while the vehicle is in motion at a high speed. However, even when the vehicle is in motion at a slow speed or if there is significant wind, a deployed top can catch the wind, e.g. like a parasail or parachute, which exerts significant force on the top. For example, if the top catches the wind, the top may be urged back towards the stowed or radar positions. If the top was locked in the deployed position, such rotational force could damage the frame members resulting in the failure of the top and/or damage to the vehicle. Similarly, if the top catches the wind, the top might create drag away from the vehicle causing significant tensile force on the frame members, means of attaching the top to the vehicle and/or the vehicle itself. Such tensile force could damage the frame members resulting in the failure of the top and/or damage to the vehicle.
To resists such forces, some tops 2, such as seen in
One disadvantage of such bars 4 is that some are permitted to be attached and detached when the top 2 is deployed and stowed, respectively. Often, bars 4 are attached and detached to connectors that are permanently or semi-permanently attached to the vehicle 6. The connectors are often considered aesthetically undesirable and can create weak points in the vehicle, e.g. holes for attachment in the fiberglass. Another disadvantage is that the typical location of a top 2 results in the front bars 4 being located on one side near where the captain's seat 8, throttle, controls, windscreen and/or other aftermarket accessories, e.g. fish finders, are located, such as seen in
Some self powered tops, for example U.S. Pat. Nos. 8,752,498, 7,438,015 and 7,389,737 to Lippert Components Manufacturing, Inc., include a central hub attached to a marine vehicle, often on each side, port and starboard, of the vehicle. The central hubs raise each side of one more of the frame members into a deployed position, which pulls, via the canvas cover, other frame members into the deployed position. Some such powered tops do not utilize bars and instead use a robust central hub and frame members, e.g. thicker walls, to resist the forces acting on the top. Even then, operating instructions for the commercial embodiment of the top disclosed in U.S. Pat. Nos. 8,752,498, 7,438,015 and 7,389,737 warns not to operate the top when the marine vehicle is in motion or in strong winds. Further, the small area of the central hub concentrates the forces from the powered top to a small area of the vehicle to which it is attached. This can cause damage to the vehicle or require additional supporting structure added to the vehicle to handle such forces. Such additional reinforcement can add cost to such tops as well as the installation.
Therefore, there is a need for a reinforced top that can resist the forces of wind and be operated during movement of the vehicle.

Other objects, features, benefits and advantages of the present invention will he apparent in this summary and descriptions of the disclosed embodiment, and will be readily apparent to those skilled in the art. Such objects, features, benefits and advantages will be apparent from the above as taken in conjunction with the accompanying figures and all reasonable inferences to be drawn therefrom.
As seen in
The top 10 embodiment seen in
The mounting bracket 18 (and/or the railing 20 or mounting surface) is configured to disperse the forces, for example from raising and lowering or from wind when the frame is deployed, along a greater area of the rail 20 of the vehicle 14 as compared to attaching the individual frame members directly to the rail of the vehicle subjecting the rail to greater point loads. The mounting bracket 18 shown in
A secondary frame member or forward bow 22 is also attached to the mounting bracket 18. Alternatively, the secondary frame member 22 could be attached to the main frame member 16, 1n the embodiment seen in
The main frame member 16 and the secondary frame member 22 are also attached to the covering 12 such that as the frame members are moved to the deployed position, for example the portion of the main frame member that is attached to the covering is moved away or remote from the portion of the secondary frame member attached to the covering, the covering will be expanded or unfolded. As the frame members 16, 22 are moved to the stowed position, the covering 12 will be folded or contracted. In one embodiment, the frame members 16, 22 are attached to the covering 12 by extending through sleeves formed in the underside of the covering. However, other means of attaching frame members to a covering are known in the industry, for example, the use of straps, snaps, fasteners, etc., the use of which would not defeat the spirit of the invention.

In the embodiment seen in
To decrease the amount of point loads on the vehicle 14 from the top 10, the mounting bracket 18 can be extended further towards the rear of the vehicle such that the end of the rear strut 26 is attached to the mounting bracket. Forces transferred to the rear strut 26 from the top 10 can be transferred to the vehicle 14 along a greater surface area of the rail 20 generally in the location of the mounting bracket.
The top 10 could also include a second or forward strut 30. In the embodiment shown in
In the embodiment seen in
While the forward strut 30 and rear strut 26 help transfer compressive forces from the top 10 to the vehicle 14, for example, a force pushing or pulling the forward end of the top 10 upwards, tensile forces may also act on the top 10, e.g. forces pushing or pulling the forward end of the top downwards. In one embodiment, the top 10 includes braces that resist the tensile forces. In the embodiment seen in
A second or forward brace 36 may be used between and attached to the auxiliary frame member 24 and another frame member, such as, for example, pad eye brackets 35 discussed above. In one embodiment seen in
When the top 10 is in the stowed position, the rear brace 34 and forward brace 36 are collapsed as seen in
In one embodiment, the rear brace 34 and the forward brace 36 are capable of being deformed to permit the top 10 to be able to be moved into a stowed position. In the embodiment seen in
As seen in
In one embodiment, a mounting bracket 18, rear strut 26, forward strut 30, rear brace 34, forward brake 36 are located on each side of the top, for example a first mount 18, first or port aft strut 26, first or port forward strut 30, port brace 34, and port forward brace 36 on the port side as seen in
In the embodiment shown above, the frame members such as the main frame member 16, secondary frame member 22 and auxiliary frame member 24 are depicted as a bow, e.g. a structural element having a port leg portion 16A., 22A, 24A and a starboard leg portion 16B, 22B, 24B connected by a generally curved middle portion 16C, 22C, 24C. In one embodiment, the port leg portions 16A, 22A are rotatably attached to the first mount 18 and the starboard leg portions 16B, 22B are rotatably attached to the second mount 18′. Likewise, the port leg portion 24A of the auxiliary frame member 24 is rotatably attached to the port leg portion 16A of the main frame member 16 and the starboard leg portion 24B of the auxiliary frame member is rotatably attached to the starboard kg portion 16B of the main frame member. However, the use of other configurations of frame members, for example, square, triangular, oval, circular, comprised of a number of components, etc., would not defeat the spirit of the invention, some examples of which can be seen in
In the embodiment shown above, the frame members such as the main frame member 16, secondary frame member 22 and auxiliary frame member 24 are depicted as being square or round tubular members. However, the use of other cross-sectional shapes of frame members, for example, oval, being solid, having thicker walls or having internal structures, would not defeat the spirit of the invention, some examples of which are seen in
In some cases, the frame members such as the main frame member 16, secondary frame member 22 and auxiliary frame member 24 will be urged to expand laterally, for example in the direction from starboard side to port side, due to forces acting on the covering 12 and/or frame. Reinforcing the frame members, such as by using different cross-sectional shapes, internal structures and/or corner bracing or truss configurations can help resist such lateral expansion. Further, additional bracing, like that disclosed with respect to the rear braces 34 and forward braces 36 could be used laterally-, for example, from the starboard side of the main frame member 16 to the port side of the main frame member.
In an alternative embodiment, one or more of the frame members have their own mounting bracket or be individually attached to the rail 20 of the vehicle 14. As seen in
In an alternative embodiment, the top 10 may be powered such that the top may be moved between the first, raised or deployed position and the second or stowed position, and alternatively the radar position, entirely on its own or in a partial manner so as to permit the top to be more easily moved by a person, In one embodiment, the main and/or secondary frame members 16, 22 could be powered, such as by a motorized hub with integrated hinges and/or mechanical levers. In one embodiment, the hinges 28, 32 could be powered to be able to open and close. Other means to (un)fold the hinges 28, 32 and/or the rear strut(s) 26 and/or the forward strut(s) 30 can include cables, pities, winches, motors, actuators, springs, lead screws, levers, gears such as spur, rack and pinion, worm, bevel, pressurized components such as pistons, bladders, balloons, etc., the use of which would not defeat the spirit of the invention.
By way of one example, one or more of the struts 26, 30 could be powered by a biasing member such as a gas shock, a mechanical or pneumatic spring, shock and/or damper, as disclosed for example, in U.S. Pat. Nos. 9,849,939, 9,815,525, 9,783,266, and 9,604,702, owned by the owner of the present application, and which are hereby incorporated herein for all purposes. Alternatively, or in addition, the frame members could be driven by gears such as disclosed in U.S. Pat. Nos. 8,752,498 7,438,015 and 7,389,737 to Lippert Components Manufacturing, Inc.
In one powered embodiment, an actuator 42, such as a linear actuator, can be attached to the frame, and moved between a first position and a second position to raise and lower at least a portion of the frame. The actuator could be a linear rod actuator, gas shock, mechanical or pneumatic spring, shock, damper, powered hinge, cam and follower, cycloidal gear box or other similar type of device that cases movement.

In one embodiment seen in
In order to cause the movement of the carriage 48 to result in the expanding or unfolding of the forward strut 30, a strut link 50 is used. In the embodiment seen in
In one embodiment, the rod end of the forward actuator 44 is extended when the top 10 is the radar position as well as in the stowed position. As the rod end of the forward actuator 44 is retracted or withdrawn from the first position (F1G. 20A) towards the second position (
When the rod end of the forward actuator 44 is in the second position and the carriage 48 is in the second carriage position, the second portion 30B is generally inline with the first portion 30A of the forward strut 30 and the forward strut expanded as seen in
In one embodiment, a first activation of the top, e.g. flipping of a switch, could result in the top 10 moving from a stowed position to a deployed position. A second activation, e.g. moving the switch in a different direction or pushing of a different button, could result in the top moving from a deployed position to a stowed position. In moving between the stowed position and deployed position, the rear actuator 42 and forward actuator 44 could operate at the same time resulting in shorter time between positions. Alternatively, one actuator could operate fully before second actuator begins to operate. Or, one actuator could begin to operate, but not complete its operation, before second actuator begins to operate. Additionally, or alternatively, one type of activation of the top could result in only one actuator operating. For example, if it is desirable to have shade from a setting or rising sun, the forward actuator 44 could move the forward strut 30 to its expanded position as seen in
In another alternative embodiment, seen in FIGS, 22-23, The carriage 48 and forward actuator 44 could be attached to, or even located in, the main bow 16. In this embodiment, one end of the strut link 50′ is pivotally attached to the hinge 32 and the other end is attached to a carriage (not shown). When the top 10 is in the collapsed position, as seen in
As the rod end of the forward actuator 44 is retracted, and the carriage moves (and thereby, the first end of the strut link 50′ moves), from a first carriage position (seen in

The grooves 68, 70 can be eccentric to cause the arms 60, 64 and, thereby, the rear strut 26 and forward strut 30 to rotate. For example, in one embodiment, the first groove 68 has a drop 74 at the beginning. As the cam 72 rotates, counterclockwise in the orientation seen in
As seen in
The grooves 68, 70 could be shaped and sized to accommodate different rotating patterns. For example, the second groove 70 could begin increasing in radius right from the start such that the forward strut 30 starts to rotate together with the rear strut 26. Alternatively, the grooves 68 70 could be located on opposite sides of the cam 72 or on different cams or the exterior surface of the cam could be shaped accordingly and the fingers 62, 66 could ride on the exterior surface of the cam without defeating the spirit of the embodiment.
In another embodiment, the forward strut 30 and/or rear strut 26 could be rotated by a cycloidal gear box 82. In one such embodiment seen in
In one embodiment seen in
Then, the second hinge 32 is activated pushing the remainder of the top 10 into the deployed position. For example, the secondary frame member 22 is rotated away from the main frame member 16. Upon some event, the second hinge 32 is deactivated and held and/or locked in position to hold the top 10 in the deployed position. The rotation of the secondary frame member 22, causes the covering 12 to expand. The expansion of the covering pulls the auxiliary bow 24 causing it to rotate away from the main frame member 16 and into the deployed position. To move the top 10 from the deployed position to the stowed position the button could be pressed again or the switch flipped in a different direction to cause the top to work in the reverse order.
Alternatively, upon pressing a button or flipping a switch, both hinges 28, 32 could be activated together to cause to the top to be moved in a shorter time period. Another alternative embodiment includes the first activation of the button or switch causing the top to move to the radar position from either the stowed or the deployed position and a second activation of the button or switch causing the top to move to the deployed position or radar position, respectively.
Any number of powered hinges could be used without defeating the spirit of the invention. Although a two powered hinge embodiment is described above, a single powered hinge could be used to move the top 10 from the stowed position to the radar position or from the radar position to the deployed position. By way of another example, four powered hinges could be used as seen in
In yet another embodiment, the rear actuator 42 could be attached to the main bow 16 as seen in
In yet another embodiment, the forward actuator 44 could be attached to the forward strut 30 as seen in
In yet another alternative embodiment, as seen in
Similar to the embodiment discussed above in which a mounting bracket 18, rear strut 26, forward strut 30, rear brace 34, forward brace 36 are located on each side of the top, a rear actuator, for example a port rear actuator and starboard rear actuator and a forward actuator, for example a port forward actuator and starboard forward actuator could be used on each side of the top. When the port aft strut and starboard aft strut are in the first aft position and the port forward strut and the starboard forward strut are in the first forward position, the aft bow and forward bow will be in the raised position, And, when the port aft strut and starboard aft strut are in the second aft position and the port forward strut and the starboard forward strut are in the second forward position, the aft bow and forward bow will be in the stowed position. And, when the port aft strut and starboard aft strut are in the second aft position and the port forward strut and starboard forward strut are in the first forward position, the aft bow and the forward bow will be in the radar position.
While the top 10 in some embodiments is shown positioned towards the rear of the vehicle, it is understood by those skilled in the art that the position of the top could be moved. anywhere between the front and the rear of the vehicle. Further, while the top 10 in some embodiments shown with the secondary frame is towards the front of the vehicle, it is understood by those skilled in the art that the top could be rotated 180 degrees. The orientation and placement of the top 10 relative to the vehicle can be adjusted due to the layout and purpose, size and configuration of the vehicle.
Although the invention has been herein described in what is perceived to be the most practical and preferred embodiments, it is to be understood that the invention is not intended to be limited to the specific embodiments set forth above. For example, although the support member is described as being used in a frame for a marine top, the support member could be used in a variety of applications including a pontoon boat (
