BACKGROUND OF THE INVENTION
The invention relates generally to protective covers and shelters for watercraft and in particular to cantilever covers including canopy frames. Boaters who moor their boats to piers are universally faced with the task of repeatedly covering and then uncovering their watercraft between storage and use configurations. While seemingly simple, this task can be daunting and can greatly diminish enjoyment of the boating experience.
Individual covers exist for most watercraft, but have to be manually taken on and off with a combination of zippers, snaps, and center poles. This task can be time consuming and physically demanding, and, for people with dexterity disabilities, virtually impossible. Often times, boaters skip boating altogether because of the difficulty associated with manual covers. As an alternative, complex and costly mechanical boat cover lifts have been proposed, for example U.S. Pat. No. 4,363,284 to Monroe provides a vertically lifting boat cover that may marginally reduce the hassle involved in covering and uncovering, but without, as in the present invention, providing full access to the boat while covered. Similarly, U.S. Pat. No. 6,688,252 to Caravella provides a liftable boat cover, but requires driving supports that span the mooring area. U.S. Pat. No. 7,353,769 to Unrast provides a cantilevered liftable canopy, which addresses the need to span the mooring area, but still requires complex mechanical action to use and does not provide access to the watercraft without lifting the canopy.
Another alternative is covered boat lifts, which lift the vehicle up into a stationary canopy. Depending on the means of providing power, this activity can be difficult, such as during power outages or when the pulley mechanism has malfunctioned, leaving the boater to temporarily revert back to individual covers. Additionally, this alternative is relatively expensive, both for the initial investment, as well as the ongoing seasonal installation done most often with barges and cranes. Lastly, the lift stations are a disruption to the natural environment, as while in the water they disturb the lake bed with underwater supports and resting pads, and during the off-season are placed helter-skelter along the shorelines, diminishing the public's use and enjoyment of the waterfront.
The present invention addresses this problem by providing a seasonally installed cantilevered canopy that may be affixed to and easily installed from the pier or dock. The canopy of the present invention is easily installed and removed for seasonal use, and it offers protection without mechanical parts or power to operate. By comparison, existing modular canopies, for example U.S. Pat. No. 5,185,972 to Markiewicz, require either opposing supports spanning the mooring area or obstructive cross-bracing on the pier (see Markiewicz at FIG. 1, wherein the posts 14 would either span a mooring area or be in-line with a pier, if the structure shown were used to shelter watercraft). The present invention's cantilevered design avoids the need to have a spanning support and the need for obstructive cross-bracing.
SUMMARY OF THE INVENTION
Accordingly, the invention is directed to a cantilevered watercraft canopy. A plurality of vertical supports provides support to a plurality of horizontal supports. First and second main struts are supported by the horizontal supports. First and second pluralities of arch members are affixed at a central attachment point to the first main strut and second main strut, respectively. The outer ends of the first and second pluralities of arch members support first and second outer struts. In the first exemplary embodiment, the inner ends of the first and second pluralities of arch members are affixed to one another, and the main struts are affixed rigidly to the horizontal supports.
In the second exemplary embodiment, first and second inner struts are affixed to the inner ends of the first and second pluralities of arch members, and the main struts are affixed rotatably to the horizontal supports. A canopy cover is affixed over the arch members and struts.
The canopy cover provides access flaps that may be held back via a closure. The vertical supports may be affixed to a dock or pier via a bracket affixed to the side of a dock or pier. In the case of a floating dock, the vertical supports may be inserted into the guide holes and supported via a stop disc. In the case of an unstable or insufficient dock, the vertical supports may be fitted with an auger pole at the bottom end and driven into the water body bed.
It is an object of the invention to provide a watercraft canopy that replaces the need to cover watercraft during non-use.
It is an object of the invention to provide a watercraft canopy that permits usable access to the watercraft during inclement weather.
It is an object of the invention to provide a watercraft canopy that is easily installed and stricken seasonally.
It is an object of the invention, in its second exemplary embodiment, to provide a watercraft canopy that is installable on and entirely from the dock or pier without requiring access from the water or a watercraft, and without spanning the mooring area.
Additional features and advantages of the invention will be set forth in the description which follows, and will be apparent from the description, or may be learned by practice of the invention. The foregoing general description and the following detailed description are exemplary and explanatory and are intended to provide further explanation of the invention.

DETAILED DESCRIPTION OF THE INVENTION
Referring now to the invention in more detail, the invention is directed to a cantilevered watercraft canopy. As shown in FIGS. 1-4, the environment of the preferred environment is installation on a dock 100 or pier such that mooring areas on both sides of the dock 100 are covered by the canopy. As depicted in FIGS. 1-4, defined within the environment are the water level 102 (the water level 102 is represented by a pair of parallel oblique lines, which define a plane within the perspective of the figures), the shore 103, and the water body bed 106 (the water body bed 106 is represented by short oblique line segments located at the base of the guide poles 101; the water body bed 106, of course, extends in all directions under the body of water in the locale of installation). In general the water body bed 106 may refer to the floor of any body of water in which the user wishes to moor watercraft—for example, a lake bed, riverbed, pond bed, seabed, etc., including the bed of an artificial body of water. While an aspect of the preferred embodiment, the presence of a dock 100 or even a body of water are not required to practice the invention, which may be installed over a mooring area having no walking access (for example, using the auger pole support option of FIG. 25), or over a location with no water at all. The invention may provide covered mooring for large exemplary watercraft 104, for example the pontoon boat shown, small exemplary watercraft 105, for example canoes, kayaks, or powered personal watercraft, as shown, or for any other type of watercraft movable at a dock 100.
In the preferred embodiment, the dock 100 is a floating dock. Currently commercially available floating docks are characterized by a system of modular configurable dock guides 100A, which form a bracket attached to the outer edge of the floating dock 100. Each dock guide 100A is pierced by a floating dock guide hole 100B. Some commercially available floating docks dispense with the floating dock guide bracket in favor of piercing the dock with the guide hole directly; in this case, the invention is installed in the provided guide holes. In ordinary operation, floating dock guide poles 101 are augured to the water body bed 106 and configured to pass through the guide holes 100B just above the water level 102. The floating dock 100 is thus allowed to move freely up and down as the water level 102 changes over time, but is restricted in its horizontal motion by the guide poles 101.
In all embodiments, the present invention relies upon vertical supports 600, each having a bottom end 600A and a top end 600B. The vertical supports 600 are preferably affixed, at the bottom end 600A, to a mounting surface, generally either the dock 100 or the water body bed 106, by any of several provided vertical support mounting means for mounting the vertical supports to the mounting surface. In the preferred embodiment, where a floating dock 100 is present, the mounting surface is provided by adding extra dock guides 100A to the dock 100. The bottom end 600A of each vertical support is inserted into a vertical support socket 2300, which is secured by a vertical support socket fastener 2301 (for example, an installed Allen bolt, as shown). The vertical support socket 2300 is located at the top end of an insertion member 2303, which fits inside the guide hole 100B. Near its top, the insertion member 2303 is surrounded by and rigidly affixed to a rigid top disc 2302, which is larger in diameter than the guide hole 100B. Thus, the insertion member 2303 and stop disc 2302 together secure the vertical support 600 with the insertion member 2303 resting within and the stop disc 2302 resting above the guide hole 600B.
An alternative embodiment provides for attaching the vertical supports 600 to a fixed dock 100. In such a configuration, the bottom end 600A of each vertical support is inserted into a bracket vertical support socket 2400 and thence into a bracket vertical support tube 2402, where it is secured by a vertical support socket fastener 2401 (for example, an installed Allen bolt, as shown). The bracket vertical support tube is affixed to a bracket flat 2403, which is affixed to the side of the dock 100 by fastening through or around the dock edge to a secondary bracket flat 2405, forming a clamp. The vertical support fasteners 2404 may be hexagonal bolts, as shown, or generally any type of bolt, screw, or the like. Together, the bracket vertical support tube 2402, bracket vertical support socket 2400, bracket flat 2403, and secondary bracket flat 2405 form a bracket, and the vertical support 600 may be understood as being inserted into and affixed within the bracket.
Another alternative embodiment provides for attaching the vertical supports 600 to an auger pole 2502 via an auger pole vertical support socket 2500 where it is secured by a vertical support socket fastener 2501 (for example, an installed Allen bolt, as shown). The base of the auger pole 2502 is fitted with an auger 2503, which is driven into the water body bed 106. This allows the invention to be practiced in the absence of a suitably stable dock 100 and in the absence of any dock or pier at all, for example in an open water mooring area.
Referring now to the canopy frame 6100 of FIGS. 6-8, the vertical supports 600 support the canopy frame 6100. Preferably, the vertical supports 600 support the entire canopy frame 6100 alone—that is, without any non-vertical elements such as cross-bracing that would obstruct access to the walking space on the dock 100 or in watercraft mooring area on the water. Affixed to the top 600B of the vertical supports 600 are a number of horizontal supports 601, each having a first end 601A and a second end 601B. The horizontal supports 601 are preferably at equal height, parallel with one another, of equal length, and extend an equal distance from the dock 100. In the preferred embodiment, as shown, the vertical supports 600 form two rows in-line with either side of the dock 100, and the horizontal supports are oriented across opposing pairs of vertical supports 600, crosswise with the dock 100. Generally, each horizontal support is affixed to the top 600B of at least one vertical support 600, however, in the embodiment shown, the two opposing pairs of vertical supports 600 are present and two horizontal supports 601 are correspondingly present, though the entire apparatus may be extended over longer docks 100 by adding additional horizontal supports 601 and opposing pairs of vertical supports 600. Attached to all of the first ends 601A of the horizontal supports 601 is a first main strut 602, and attached to all of the second ends 601B of the horizontal supports 601 is a second main strut 603. Depending upon the embodiment, the main struts 602 and 603 may be affixed rigidly or rotatably to the horizontal supports 601. In the preferred embodiment, and as shown, the main struts 602 and 603 are long relative to the distance between the opposing pairs of vertical supports (about the width of the dock 100) such that the main struts 602 and 603 are parallel to one another, horizontal, and substantially distal to the vertical supports 600 to a length sufficient to extend over target watercraft such as the large exemplary watercraft 104, moored width-wise, as shown, or the small exemplary watercraft, moored lengthwise, as shown.
Referring still to the canopy frame 6100 of FIGS. 6-8, a set of first arch members 604 and a set of second arch members 605 are provided. Each set of arch members 604 and 605 provides sufficient arc to cover about half of the total intended arc of the canopy frame 6100. For both the first and second exemplary embodiment the canopy frame 6100 may be understood as defining a barrel vault that is open and unobstructed at either end, as shown in FIGS. 6-7; the barrel vault thereby provides unobstructed and enclosed access to watercraft moored in the mooring area. As understood from the figure, the total arc of the canopy frame 6100 is intended to be substantially less than 180° of a circle that is oriented in a vertical plane orthogonal to the dock 100 whose radius is substantially larger than the height of the canopy frame 6100. Alternative embodiments, of course, may provide a different roof shape, for example that of a pair of angled awnings or a rectangular or irregular roof shape defined by the arch members 604 and 605 not conforming to sections of arc. Each of the first arch members 604 has defined an inner end 604A, a central attachment point 604B, and an outer end 604C. Each of the second arch members 605 has defined an inner end 605A, a central attachment point 605B, and an outer end 605C. The first arch members 604 are affixed, at their central attachment points 604B, to the first main strut 602. The second arch members 605 are affixed, at their central attachment points 605B, to the second main strut 603. All of the first arch members 604 are of equal length (both linear length and arc length), oriented such that they are parallel to one another, perpendicular (at the point of attachment) to the first main strut 602, and arched inward or downward with respect to the first main strut 602. All of the second arch members 605 are oriented such that they are of equal length (both linear length and arc length), parallel to one another, perpendicular (at the point of attachment) to the second main strut 603, and arched inward or downward with respect to the first main strut 603.
Referring still to the canopy frame 6100 of FIGS. 6-8, a first outer strut 606 and a second outer strut 607 are provided. The first outer strut is affixed to all of the outer ends 604C of the first arch members 604. The second outer strut 607 is affixed to all of the outer ends 605C of the second arch members 605. Thus, in its most generic form, the canopy frame 6100 may be understood as comprising the first arch members 604, the second arch members 605, the first main strut 602, the second main strut 603, the first outer strut 606, the second outer strut 606, and the horizontal supports 601. Generically, the canopy frame 6100 is substantially covered by a canopy cover 5100 affixed thereto, which may be as described below or may be any fabric covering according to methods and principles well known in the art. The outer struts 606 and 607 hang at a height defining the bottom of the canopy, which is preferably at a level at which the target watercraft, such as the large exemplary watercraft 104 of the figures, can just pass under the canopy without colliding. This permits the user to moor watercraft uncovered beneath the canopy without risking damage to the watercraft from the elements.
In the first exemplary embodiment of FIG. 6, the first main strut 602 and second main strut 603 are rigidly affixed to the horizontal supports 601 such that they do not rotate. Further, each of the first arch members 604 is joined at its inner end 604A to the inner end 605A of one of the second arch members 605, and vice versa such that each of the second arch members 605 is also joined to a first arch member 604 with no extra arch members 604 or 605. Equivalently, it is understood that there are equal numbers of arch members 604 and 605, and each is aligned with a corresponding one of the other. In the first exemplary embodiment, the inner ends 604A and 605A of the first arch members 604 and second arch members 605 is achieved with a central arch connection 608, which may be of any joining fastener type but is preferably of the straight connector 1600 type discussed below.
In the second exemplary embodiment of FIGS. 7-8, the first main strut 602 and second main strut 603 are rotatably affixed to the horizontal supports 601 such that they can turn, at least somewhat freely (substantial friction allowing the main struts 602 and 603 to retain their rotational position unless pushed or pulled by hand is preferable) while connected to the horizontal supports 601. The rotatable connection is minimally required during installation and striking of the canopy frame 6100, but may persist throughout the use of the canopy frame 6100. In the second exemplary embodiment, the arch members 604 and 605 are preferably weight-balanced about the main struts 602 and 603 such that they function as their own counterweights, rendering rotation of the main struts 602 and 603 easily done by hand. Further, a first inner strut 700 and a second inner strut 701 are provided. The first inner strut is affixed to all of the inner ends 604A of the first arch members 604. The second inner strut is affixed to all of the inner ends 605A of the second arch members 605. When placed in the use configuration of FIG. 7, the inner struts 700 and 701 are positioned proximate to one another and directly overhead of the dock 100, as shown. In the use configuration, the first inner strut 700 is secured to each horizontal support 601 by a set of first secondary vertical supports 702. Each first secondary vertical support 702 is removably affixed at its bottom end 702A to one of the horizontal supports 601 and at its top end 702B to the first inner strut 700. Similarly, in the use configuration, the second inner strut 701 is secured to each horizontal support 601 by a set of second secondary vertical supports 703. Each second secondary vertical support 703 is removably affixed at its bottom end 703A to one of the horizontal supports 601 and at its top end 703B to the second inner strut 701. The connection between the secondary vertical supports 702 and 703 (either is represented as reference number 2600 in FIGS. 26-27) and the horizontal supports 601 is made by a secondary vertical support pin 2601, which penetrates a collinear horizontal support pinhole 2602 and a secondary vertical support pinhole 2700. The joint is achieved by inserting the secondary vertical support element 2600 into the secondary vertical support access hole 2603 in the top surface of the horizontal support 601. The second exemplary embodiment is thus advantaged because the rotation of the main struts 602 and 603 between the installation configuration of FIG. 8 and the use configuration of FIG. 7 permits the invention to be installed from the dock 100 without the need to stand on a watercraft or in the water.
In both the first and second exemplary embodiments, connections between the elements of the canopy frame 6100 may be achieved by any known means, and the elements of the canopy frame 6100 may be of any material or shape profile. However, in the preferred embodiment, the structural elements, specifically the vertical supports 600, the horizontal supports 601, the first main strut 602, the second main strut 603, the first arch members 604, the second arch members 605, the first outer strut 606, the second outer strut 607 and, in the second exemplary embodiment, the first inner strut 700, second inner strut 701, first secondary vertical supports 702, and second secondary vertical supports 703 are all made of galvanized steel pipe or beam, or alternative materials such as aluminum, composite, plastic, or wood. The frame elements may be manufactured to length or, preferably, are assembled from short modular segments having male and female connectors such that the entire frame is easily transported, assembled, and stored. Those frame elements that are hollow are preferably pierced with weep holes providing for the drainage and evaporation of internally accumulated moisture.
The connections between the structural components are preferably formed with the pipe or beam connectors of FIGS. 16-18. A straight connector 1600 may join two inline frame elements 1601 and secure each with a frame connector fastener 1602. Similarly, a right-angle connector 1700 may join two frame elements 1601 and secure them via the same frame connector fastener 1602. Similarly, a T-connector 1800 may join two or three (with a central joint) frame elements 1601 and secure them via the same frame connector fastener 1602. The frame connector fastener 1602 preferably is formed from a welded nut within the frame connector 1600, 1700, or 1800 that is threaded with an Allen bolt. The same size Allen bolt is preferably used in the vertical support socket fastener 2301, the bracket vertical support socket fastener 2401, and the auger pole vertical support socket fastener 2501, and any other bolt connections such that the entire frame may be assembled and stricken with a single tool: the one Allen wrench of the particular size chosen. Referring still to the frame connectors 1600, 1700, and 1800, the Applicant has identified and applied commercially available Kee Klamp® brand connectors with success in the context of the present invention.
In either the first or second exemplary embodiment, a storage net 2100 may be provided. The storage net 2100 provides sheltered storage intended for boating accessories such as life vests, tubes, flotation toys, and the like. The net 2100 is preferably suspended at least between any two of the horizontal supports 601, and may optionally be further affixed to the first main strut 602 or second main strut 603. In the preferred embodiments, as shown in FIGS. 3-4, two cargo nets 2100 are provided on either side of the pier. The front and back edges are suspended between the two horizontal supports 601, and the outer edges are suspended from the main struts 602 and 603. The inner edges are not directly suspended from any structure and terminate in-line with the vertical supports 600. This provides a central access space over the dock 100 to the storage volume created by the net 2100. More generally, the storage net 2100 may be suspended between any two parallel frame elements, including the horizontal supports 601, main struts 602 and 603, and the outer struts 606 and 607. FIG. 22 provides the detail of the preferred net element fasteners. The net 2100 may be fastened at any number of fastening points by a net cord 2200, which wraps around the supporting frame element 2204 and secured via a net cord ball 2201 passed through a net cord loop on the opposite end of the net cord 2200. A double hook 2203 hooks to both the net cord 2200 and the net 2100, as shown. In alternative configurations, hooks may be installed on the relevant frame members or, equivalently, on the net itself, for a bungee net. Additionally, rope knots or alternative netting fasteners may be employed. Additional storage solutions may be installed, for example a single-attachment mesh bag may store water toys, swimwear, or other small items. Additional storage solutions may include a clothesline or equipment hoist (for example, for overhead storage of a kayak).
Referring now to the canopy 5100, shown in disassembled plan view in FIG. 9, the preferred embodiment of the canopy comprises a first canopy top element 500, a second canopy top element 501, a pair of first canopy side elements 502, and a pair of second canopy side elements 503. As shown, the first canopy top element 500 is approximately rectangular and has an inner edge 902, an outer edge 904, and two side edges 906. Similarly, the second canopy top element 501 is approximately rectangular and has an inner edge 903, an outer edge 905, and two side edges 907. Each of the first canopy side elements 502 is defined to have a first side element inner edge 908, a first side element bottom edge 910, and a first side element curved top edge 912. Similarly, each of the second canopy side elements 503 is defined to have a second side element inner edge 909, a second side element bottom edge 911, and a second side element curved top edge 913. The curved top edges 912 and 913 are shaped to match the arc of the first arch elements 604 and the second arch elements 605, respectively. The outside surface of the canopy side elements 502 and/or 503 may have affixed thereto a logo placement 508 whereon branding or other indicia may be printed. Additionally, the first and second canopy top elements 500 and 501 as well as the canopy side elements 502 and 503 may have affixed to their lower edges a loosely hanging skirt of additional material, which may provide added protection against the entry of dirt, wind, and moisture.
The canopy components are joined by canopy cover fasteners 901, which are present along the first top element inner edge 902, the second top element inner edge 903, the first top element side edges 906, the second top element side edges 907, the first side element curved top edges 912, and the second side element curved top edges 913. The canopy cover fasteners 901 may take the form of stitching, zippers, hook and loop fastener strips, buttons, snaps, etc. Along the first top element inner edge 902 and the second top element inner edge 903, the canopy cover fasteners 901 form a top element removable fastening means for removably fastening the first top element 500, along the first top element inner edge 902, to the second top element 501, along the second top element inner edge 903. Thus, in the case of the top element inner edges 902 and 903 removable fasteners, and not stitching, are preferred. Along the first and second side element top edges 912 and 913, and along the first and second top element side edges 906 and 907, the canopy cover fasteners 901 form a side element top edge fastening means for fastening each of the first pair of side elements 502, along the first side element top edge 912, to the first top element 500, along the first top element side edges 906, and for fastening each of the second pair of side elements 503, along the second side element top edge 913, to the second top element 501, along the second top element side edges 907. In the case of the side elements 502 and 503, a non-removable fastening means, i.e. stitching, is preferred. Notably, the first and second canopy top elements 500 and 501 have, within their outer edges 904 and 905, respectively, notches 900, which accommodate the arch members 604 and 605 at T-connectors 1800, as shown in FIG. 20, which shows a cross section the outer strut 2003 (either the first outer strut 606 or the second outer strut 607) and the canopy cover top fastener 2001. The canopy top fastener 2001 is preferably hook and loop fabric strips, though other removable fastening means, such as ties, snaps, buttons, etc. may be employed. In the case of the second exemplary embodiment, pairs of hook and loop fasteners are preferably provided on the inside surface of the first and second top canopy elements 500 and 501 in-line with the first and second inner struts 700 and 701, respectively such that the canopy cover 5100 is affixed to both rotatable portions of the canopy frame 6100.
The first side element inner edges 908 and the second side element inner edges 909 are removably joined by a side element fastening means for fastening the first pair of side elements 502 to the second pair of side elements 503. To achieve this means in its most generic form, the canopy cover fasteners 901 may be extended over the side element inner edges 908 and 909, which may be made parallel so as to be joined by a zipper, hook and loop fastener strip, buttons, snaps etc. However, in the preferred embodiment, the first side elements 502 and second side elements 503 are both shaped to have a first door flap 504 and second door flap 505, respectively, along their inner edges 908 and 909. The door flaps 504 and 505 preferably overlap and are movable between an open configuration (FIG. 11) and a closed configuration (FIG. 10). With respect to the closed configuration, a door closing fastener 507 is configured for releasably fastening the door flaps 504 and 505 into the closed configuration, and is present on the door flaps 504 and 505, may take the form of a hook and loop fastener strip, or alternatively buttons, snaps, hooks, etc. In embodiments where the door closing fastener 507 is a horizontally oriented hook and loop fastener strip, as shown in FIG. 10, complementary hook and loop fastener faces may be placed on the inside face of one and outside face of the other of the first door flap 504 and second door flap 505; alternatively, complementary hook and loop fastener strips may be placed on both the inside face and outside face of both the first door flap 504 and the second door flap 505. Thus, in the preferred embodiment, the door closing fastener 507 provides the side element fastening means for fastening the first pair of side elements 502 to the second pair of side elements 503. Additionally, the door closing fastener 507 provides a detachable and reattachable closed door flap fastening means for fastening the first door flap 504 and the second door flap 505 in the closed configuration. Further, the door flaps 504 and 505 may be fastened in the open configuration of FIG. 11 provided door opening fasteners 506, which may be snaps, buttons, hooks, hook and loop fasteners, etc. This forms a detachable and reattachable open configuration door flap fastening means for fastening the first door flap 504 and the second door flap 505 in the open configuration. The door flaps 504 and 505 may be fastened open inside or outside of the canopy; the figures show the door flaps 504 and 505 on the inside, for example the inside view of FIG. 13. The angled overlapping shape of the door flaps 504 and 505 provides fault-tolerance for deformation in the shape of the arch members 604 and 605, whether during manufacturing or after installation, for example due to deflection. In various embodiments, this fault tolerance is achieved by the door closing fastener 507 being a horizontally (or, inline with the direction of overlap) positioned hook and loop fastener strip, as depicted in FIGS. 5 and 10, allowing the degree of overlap of the door flaps 504 and 505 to be adjusted. Further, the particular angled shape referenced herein may be understood, as depicted in FIGS. 5 and 10, as each of the door flaps 504 and 505 being acutely angled as measured between the door flap edge 504A or 505A and the horizontal, and with the vertex being located at the corner of the corresponding side element 502 or 503. Accordingly, the triangular overlap region 590 between the door flaps 504 and 505 is triangular in shape with the scale of the triangle dependent on the degree of overlap. As shown, the door closing fastener 507 is located within the triangular overlap region 590. Further, as shown, the door closing fastener 507 is translationally adjustable (translationally, as used here, meaning in the long dimension of the hook and loop fastener strip, as opposed to in the short dimension (distally) or some other angle (rotationally)), which allows the size of the overlap region to be scaled, thus accounting for deflection by allowing the fit of the canopy cover 5100 to be corrected. As an alternative, the door flaps 604 and 605 may be replaced by a single roll-up or pull-up drapery style covering.
The canopy top elements 500 and 501 are preferably made from a waterproof or water resistant vinyl, canvas, or other fabric covering. The canopy side elements 502 and 503 may be made of a similar material. In the preferred embodiment, however, a portion of the top elements 500 and 501, specifically a rectangular region along the inner edges 902 and 903, may be understood as the first canopy inner top element 500A and the second canopy inner top element 501A. These and the canopy side elements 502 and 503, including the door flaps 504 and 505, are preferably made of a transparent material, for example, a transparent mesh fabric material or a clear vinyl material. FIGS. 3-4, 34-43 display the transparency effect in scene view. The transparency allows light to enter such that the user can see the surrounds during daylight via the inner top elements 500A and 501A, and to see the contents of the canopy from outside or approaching persons or watercraft from inside, via the side elements 502 and 503 and door flaps 504 and 505. Additionally, where a transparent mesh screening material (which is preferable) is used, the structure has superior air venting properties, which minimize air drag forces during storms and weather, and also allow for heat and moisture to be vented from the canopy interior. Further, in the second exemplary embodiment, the interface between the main material of the first and second canopy top elements 500 and 501 may provide a wedge (or a dedicated wedge may be provided) into which a reinforcement element 1900, a flat flexible plastic strut, may be frictionally inserted; this maintains the arch of the canopy in the top region between the inner struts 700 and 701.
FIGS. 8, 14-15, 40-43 show the installation configuration of the second exemplary embodiment with the preferred canopy. The second exemplary embodiment is assembled and the main struts 602 and 603 are allowed to rotate such that the arch members are tilted upward as in the first installation configuration of FIG. 8. The canopy 5100 is then assembled in halves as in FIG. 14, and draped over the frame 6100 in the installation configuration, as in FIG. 15. The main struts 602 and 603 may then be rotated back into the use configuration and, optionally, secured there, yielding the second installation configuration of FIGS. 40-43.
