Stowing a bimini top for a tower structure that is associable with a watercraft can be difficult and inefficient from a standpoint of both a time and storage space. Accordingly, a need exists in the art for a bimini top that can be easily and efficiently stowed.
Watercraft are commonly equipped with adjustable awnings such as, for example, a convertible bimini top. Typically, a bimini top includes a collapsible frame assembly supporting a flexible cover. In many designs, the bimini top can be arranged in multiple positions including a closed position and a fully deployed position. In the closed position, the frame and cover are collapsed and may be held together via a boot that wraps around the collapsed cover. In the fully deployed position, the front support structure is positioned upwardly toward the bow of the boat while the rear support is positioned upwardly toward the stern, thus deploying the cover and providing shelter thereunder.
Deployment of these convertible bimini tops is typically performed manually. There is therefore a need to develop a system for automatically closing and stowing a bimini top.

Referring now to the FIGS., an example of a bimini system 10 is shown. The bimini system 10 includes a bimini assembly 20 having a frame 22 that is adapted to support a covering or material 24 thereon is illustrated. As shown, the bimini frame 22 may include several pieces that are formed from a strong, durable, corrosion-resistance material, such as a stainless steel or aluminum alloy for example. The frame 22 includes a substantially identical first support member 26a and second support member 26b coupled at a first end 28 to a structure 30 of a vehicle, watercraft, or boat, such as a tower or arch for example. The first end 28 may be coupled to the structure 30 directly, or through another component, such as a side plate or bracket 32 for example. In the illustrated, non-limiting embodiment, the first end 28 of the first and second support members 26, 26b are rotatably mounted to the tower structure 30, the first end 28 of the first support member 26a being disposed adjacent an inner surface of a first side 34 of the tower 30 and the first end 28 of the second support member 26b being arranged at an inner surface of a second, opposite side 36 of the tower 30. Although the first and second support members 26a, 26b are illustrated and described as being mounted to an inner surface of the tower structure 30, in other embodiments, the support members 26a, 26b may alternatively be mounted to an outer surface of the tower structure 30 or to another portion of the vehicle entirely.
The bimini frame 20 additionally includes one or more bows 40 raised and extending between the first and second support members 26a, 26b. Each bow 40 typically includes a tubular member formed in a substantially U-shaped configuration having a crossbar extending between opposite side legs which are connected to the support members 26a, 26b. However, a bow 40 having another configuration is also contemplated herein. In the illustrated, non-limiting embodiment, the frame 22 includes three separate bows arranged at different positions along the length of the first and second support members 26a, 26b. As shown, the frame 22 includes a rear bow 40a, which is coupled to a second end of both the first and second support members 26a, 26b, an intermediate bow 40b, which is coupled to a central portion of the first and second support members 26a, 26b, and a front bow 40c which is also coupled to a central portion of the first and second support members 26a, 26b at some location between the first end 28 and the intermediate bow 40b. However, it should be understood that that bimini frame 22 illustrated and described herein is intended as an example only, and that a bimini frame 22 having any suitable configuration is within the scope of the disclosure. For example, the bimini frame 22 may have any number of bows 40, or alternatively, may have one or more members coupled to the first and/or second support members 26a, 26b individually.
The bimini assembly 20 additionally may include a permanent or removable cover 24, formed from any suitable material, including but not limited to canvas, plastic, etc. for example, that stretches across the frame 22 and is secured thereto via one or more affixing mechanisms. Examples of such affixing mechanisms include Velcro®, ties, snaps, and other suitable fasteners. In the illustrated, non-limiting embodiment, the cover 24 includes one or more openings or pockets through which each of the bows 40 of the frame 22 extend to couple the cover 24 to the frame 22. Alternatively, the cover 24 may include flaps that are configured to wrap about each of the bows 40 of the frame 22 and secure to another portion of the cover 24.
As shown, each of the bows 40 is movable between a first, extended position, (
Transformation of the bimini assembly 20 between an open configuration and a closed and/or stowed configuration may be performed automatically, such as in response to operation of a switch or button for example. In the illustrated, non-limiting embodiment, the bimini assembly 20 includes one or more actuation systems for automatically transforming the bimini assembly 20 between the open configuration, the closed configuration, and the stowed configuration. As shown, the actuation system includes at least one first actuator 50 is mounted to a portion of the tower structure 30 and is operably coupled to a portion of one of the first support member 26a and the second support member 26b, such as between the first end 28 and the front bow 40c. Although two first actuators 50 are shown in the FIGS., one associated with each of the first support member 26a and the second support member 26b, embodiments having only a single first actuator 50 for moving both the first and second support member 26a, 26b are also within the scope of the disclosure.
The at least one first actuator 50 is operable to movie the first and/or second support member 26a, 26b between a first position, in which the support member 26a, 26b is generally parallel to the sides 34, 36 of the tower structure 30, and a second position, in which the support members 26a, 26b extend at an angle relative to the side of the tower structure 30, such as within 10 degrees of horizontal for example. In embodiments including multiple first actuators 50, operation of the plurality of first actuators 50 may be synchronized to enhance the smoothness of the transformation of the first and second support members 26a, 26b between the first and second positions.
In an embodiment, a second actuator 52 is mounted to one of the first support member 26a and the second support member 26b and is operably coupled to the rear bow 40a to move the rear bow 40a between the retracted and extended positions. One second actuator 52 may be sufficient to move the rear bow 40a. However, in other embodiments, as shown, the system 20 may include two second actuators 52, mounted to the first and second support member 26a, 26b respectively, and coupled to opposing sides of the rear bow 40a. In embodiments including multiple second actuators 52, operation of the plurality of second actuators 52 may be synchronized to enhance the smoothness of the transformation between the extended and retracted positions. Further, operation of one or more the second actuators 52 may, but need not be limited to when the first and second support members 26a, 26b are in the second position, or transforming between the first and second positions. The first and second actuators 50, 52 are shown as hydraulically or pneumatically powered linear actuators; however, any suitable actuation mechanism is considered within the scope of the disclosure. Further, although first and second actuators 50, 52 are illustrated and described for transforming the frame 22 between an open and closed or stowed configuration, it should be understood that other configurations of the actuation system may be used based on the configuration of the bimini frame 22.
The bimini system 10 may additionally include a gathering system configured to automatically gather the material of the cover 24 as the bimini assembly 20 transforms from the open configuration to the closed configuration. In an embodiment, best shown in
As the bimini assembly 20 is transformed between the open configuration and the closed configuration, a force is applied to the one or more tension straps 56. In an embodiment, a length of each tension strap 56 is less than the length of the cover 24 such that application of a force to the tension strap 56 facilitates rotation of each of the bows 40 of the frame 22 to rotate toward a retracted position. Further, as the bows 40 rotate, the straps facilitate folding or gathering of the material of the cover 24 disposed between adjacent bows 40. It should be understood that any number of folds, puckering, or gathered portions of material may be formed as the bimini frame transforms from the open position to the closed position. The gathering system may be suitable to gather all or at least a portion of these folds.
In an embodiment, best shown in
Although the roller of
With reference now to
When transformation of the bimini assembly 20 between an open configuration and a closed configuration is initiated, the gathering mechanism 70 is operated, such as by driving the roller about its axis X for example, or by driving each of the individual spools about a respective. In an embodiment, operation of the gathering mechanism 70 may be used to initiate transformation of the bimini assembly between an open configuration and a closed configuration. Alternatively, operation of one or more of the actuation mechanisms may initiate transformation of the bimini assembly 20. As the gathering mechanism 70 operates, a force is applied to each of the plurality of tension straps 56, causing the bows 40a, 40b, 40c to pivot about their respective axes from the extended position toward the retracted position. In some embodiments, this force applied to the rear bow 40a causes the movable portion of the at least one second actuator 52 associated therewith to retract. At substantially the same time, the at least one first actuator 50 gradually lowers the distal end of the first and second members 26a, 26b into the first position. The first support member 26a and the second support member 26b remain generally parallel to one another throughout the transformation of the frame assembly 22 between the open and closed configurations.
As the bows 40a, 40b, 40c pivot, the material of the cover 24 is folded or gathered by the continuous tension applied to the cover 24 via the engagement between the gathering mechanism 70 and the tension straps 56. Because the first and second support member 26a, 26b are rotated relative to the tower structure 30 simultaneously with the rotation of the bows 40a, 40b, 40c, the plurality of bows 40a, 40b, 40c may be generally vertically aligned despite their difference in height once reaching the retracted position. Although the tension straps 56 are illustrated and described herein as being wound about a gathering mechanism, in other embodiments, another suitable gathering mechanism, such as one or more springs or weights located at or in the tower structure 30 or even gravity for example, may be used to effectively gather the material of the cover 24.

With reference to
In the illustrated, non-limiting embodiment, the actuated door 82 of the boot includes a frame 84 having a fabric or flexible material 86 affixed thereto. However, in other embodiments, the boot 80 and/or actuated door 82 may be formed from at least one of a composite or metal material. In an embodiment, as shown, a portion 88 of the material extends over the top of the bimini assembly 20 and is affixed to a portion of the tower structure 30 or to a portion of the bimini assembly 20. In the illustrated non-limiting embodiment, the actuatable door 82 of the boot 80 is rotatable about an axis between the first position (
Once the bimini assembly 20 is arranged in a closed configuration, the actuatable door 82 of the boot 80 may be automatically positioned in overlapping arrangement with the rear bow 40a to enclose the gathered cover 24 of the assembly 20 within the boot 80. The actuatable door 82 of the boot 80 may be driven by any suitable movement mechanism (not shown), including but not limited to a motor or an actuator for example. The same switch or button used to retract the bimini assembly 20, or alternatively, a different switch or button, may be configured to communicate with the movement mechanism to initiate automatic movement of the boot 80 to selectively stow the bimini assembly 20. Further operation of the button or switch may cause the boot 80 and the bimini assembly 20 to move in reverse order, first opening the boot 80 and the transforming the bimini assembly 20 to an extended position.
