DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
The following discussion describes in detail at least one embodiment of the present invention. This discussion should not be construed, however, as limiting the present invention to the particular embodiments described herein since practitioners skilled in the art will recognize numerous other embodiments as well. For a definition of the complete scope of the invention the reader is directed to the appended claims. FIGS. 1 through 14 illustrate the present invention wherein a canopy for recreational use is disclosed and which is generally indicated by reference number 10.
Turning to FIGS. 1 and 2, therein is shown the present invention 10 showing a watercraft 12 to which is attached an upright support post or stanchion 14 having a canopy 16 disposed thereon. The canopy 16 is supported between a first and second 18, 20 side frame members or rods which are flexible and resilient in nature similar to what a fiberglass or graphite composition rod would exhibit and the from tip of canopy 16 may be attached to upright support 14 using a piece of material or member 33. Each rod 18, 20 may be made of one piece or two pieces and a two piece unit would require a conventional ferrule or the like shown at 22 with connector pins 27 or the like in order to connect the pieces of the rod 18, 20 to each other. Also, a cross member 24 is shown underneath the canopy 16 so as to provide vertical support for the canopy in order to keep it from ripping or tearing as would be caused by wind or movement of the boat or watercraft 12 and T-connectors 26 or the like are shown on each side for connecting an end of the cross bar 4 to each of the flexible rods 18, 20. The canopy 16 is connected to the rods 18, 20 using a plurality of rings 28 passing through multiple eyelets 30 disposed near the edge of the canopy. An alternative embodiment for attaching the canopy 16 to rods 18, 20 is shown in FIG. 5. The flexible rods 18, 20 are attached to an upper end of the upright support or stanchion 14 by having an end 32 of each rod pass through respective apertures 34, 36, 38, 40 of the upright support 14. An end of rod 18 extends or passes through aperture 34, 36 and an end of rod 20 passes through aperture 38, 40 as best shown in FIG. 2. This very simple construction technique reduces the cost and time of manufacturing the present invention 10. The ends of the rod 18, 20 being under inherent resilience force are frictionally held firmly in the aperture pairs 34, 36, 3840 as the ends 32 of the rods 18, 20 pass completely through the mating opposing walls of the upright support 14. Also shown is an up and down height adjustment mechanism for the upright member 14 wherein a plurality of apertures 50 are shown passing through the inner and outer upright support 14 so that the inner upright support is telescopically connected to the outer upright support using a plurality of apertures 50 having a pin 52 pass through a selected aperture pair as would be done in the standard manner by one skilled in the art so as to make the canopy 16 of the present invention 10 height adjustable in an up-down direction. Also shown is a line 54 which provides means to rotate the canopy 16, connected to an end of canopy 16 and having an end tied to cleat 56 which line can be used to control and thereby to reposition, move or rotate the canopy 16 about the watercraft 12 to a user selected position. Also shown is a fisherman or user 60 in boat 12 holding a rod and reel 62 in his hand with a lure and line 64 thereon illustrating how a user can cast from underneath the canopy 16 so that the rod does not hit anything during the cast. An alternate mounting means for the upright support post 14 is shown by rod holder 47 disposed on an inside wall of the boat 12 with a lower end of the post 14 inserted in the rod holder so that the post is rotatable in the rod holder. Also shown is an exemplary mounting device 48 for connecting the upright support 14 to a surface 42 of the watercraft 12 or the like wherein the mounting device has a base 44 for receiving fasteners 45 extending into the surface 42 so as to be fixed in place and a middle portion 46 which is generally pivotable and/or rotatable and a pole mounting portion 49 to which the upright support 14 is connected. Generally, it is expected that the upright support 14 would be removably fixed in place on a supporting structure, such as a watercraft 12 or rod holder 47, so that the upright support is disposed in substantially the upright position although the upright support may be permanently mounted on the supporting structure.
Continuing with FIG. 2 also shown therein is a lighting system including a plurality of lights 134 disposed on canopy 16 in a spaced apart relationship about the canopy so as to provide light to users 60 disposed underneath the canopy during times of darkness or low light conditions. The lights 134 may be any suitable type light, e.g., incandescent, LED (light emitting diode), or the like and are electrically connected to each other by any suitable type, e.g., series or parallel, electrical wiring harness 136. Lights 134 are powered by an alternative power source such as a single battery or a multiple battery pack 138 which may be a non-rechargeable or a rechargeable battery being connected by any suitable electrical connection 140 to a battery recharger 142, if needed, all of which components receive electrical energy from the photovoltaic cells 72 or the like which would be expected to be mounted on the top side of the canopy 16 so as to produce electrical energy for conduction through electrical output wires 74, 76 which are discussed in more detail relative to FIG. 5.
Turning to FIG. 3, therein is shown an enlarged exemplary mounting device 48 for connecting the lower end of upright support 14 to a surface 42 of the watercraft 12 or the like wherein the mounting device has a base 44 for receiving fasteners 45 and a middle portion 46 which is generally pivotable and/or rotatable and a pole mounting portion 49 to which the upright support 14 is connected. Many different types of mounting devices 48 could be used with upright support 14 for connection to many types of separate structures such as chairs or the like.
Turning to FIG. 4, therein is shown an enlarged view showing the lower end of the upright support 14 having a tip 15 thereon for insertion into a different support structure such as the ground 58 as would occur with sand at a beach.
Turning to FIG. 5, therein is shown an alternative embodiment of the present invention 10 showing the canopy 16 being extended or stretched between rods 18, 20 wherein the rods are each inserted into conventional sleeves 66 disposed on and extending along first and second sides or edges of the sheet of material of the canopy. Each sleeves 66 has a hole or rodhole 68 therein through which the rod 18, 20 is inserted into or removed from the sleeve and the sleeve extends substantially entirely along the edge of the canopy 16 from a front to rear end thereof. The rods 18, 20 could be one piece or two piece for easier folding, and storage. Also shown on the canopy 11 is at least a portion of the sheet of material making up the canopy including solar cell fabric 70, wherein as used in this specification, the solar cell fabric 70 includes photovoltaic cells 72 attached to a surface thereof, or embedded therein, or stitched into the fabric, or built into the layers around the fiber of the fabric, or otherwise included as a part of canopy 16. The entire canopy 16 could be made of solar cell fabric 70 if so desired or the canopy could also be made so that part of the canopy has no solar cell fabric and part of the canopy has solar cell fabric. As used in this specification, photovoltaic cells are generally considered to be specialized electrical devices that convert visible light from the sun into some form of direct current electricity and are sometimes referred to as solar cells or solar panels. Also, some photovoltaic cells can convert infrared or ultraviolet radiation into direct current electricity. Direct current electrical output wires 74, 76 from solar cell fabric 70 are also shown wherein 74 is a positive polarity output and 76 is a negative polarity output which could be approximately 12 volt however the operating current and voltage would be determined by the load. Electrical energy output from all photovoltaic cells 72 of the solar cell fabric 70 would be connected to and thereby delivered to the direct current electrical output wires 74, 76 as indicated by electrical interconnections 82. The direct current output 74, 76 could terminate in an exemplary electrical connector 77, e.g., an inline DC (direct current) barrel power plug also called a barrel connector, as shown in FIG. 5, and could be used, for all purposes, for example, providing power for a USB charger to recharge cell phones, all other wireless and wired communication devices, or watercraft 12 batteries. Wires 74, 76 could be connected to all types of electrical connectors 77 including DC connectors and plugs, cylindrical and snap and lock connectors, all IEC connectors, cigar sockets and plugs, USB (universal serial bus) and HDMI connectors, pin plugs and many other types of connectors and plugs as commonly used by society and the marine industry and could be converted to AC (alternating current) current by using a converter so as to power all AC type electrical devices. Further, wires 74, 76 could be connected at 77 to many types of electrical circuits for all purposes including powering all types of electrical devices including wireless or wired devices including radios, GPS and radar systems or storing electrical energy in batteries or related devices. In short, the electrical output from wires 74, 76 could be used for any and all known purposes. Also shown is a hand 78 of a user to illustrate that a hand of a user can be used to provide means to rotate the canopy 16 and the upright support post 14 along with line 54. Also, the rear ends of the flexible, fiberglass rods 18, 20 may be squeezed inwardly toward each other and tied to each other for securement using line 86. Other previously disclosed items are also shown.
Turning to FIG. 6, therein is shown the top of the upright support post 14 showing the cross-crossed rods 18, 20 and apertures 34-40 showing the angle 80 between the rods which is expected to be in the range of about 30 to 120 degrees with respect to each other. The size of the angle 80 depends on the diameter, stiffness and resilience of rods 18, 20 wherein a larger diameter rod would require less stiffness and a smaller diameter rod would require greater stiffness to maintain the canopy in a stretched out disposition between the rods. Thus rods 18, 20 need to be effectively sized so that the rods become bowed enough to provide an effective amount of lateral tension to support the canopy in a stretched out disposition. The cross-cross portion 84 of rods 18, 20 is also shown. An optional clip 88 may be used to removably secure the front ends of rods 18, 20 in apertures 36, 40 so the rods cannot accidently become dislodged or disassembled wherein the clip has a first end removably attached to rod 18 and a second end removably attached to rod 20. In order to disassemble the present invention 10, the optional clip 88 would first be removed.
Turning to FIG. 7, therein is shown an alternative exemplary mounting device (somewhat similar to mounting device 48 of FIG. 3) using a conventional marine seat pedestal assembly 90 having a fixed or rotatable seat plate 92 on its upper end suitable for having a marine seat mounted thereon, pedestal shaft 94 and pin 96 on its lower end wherein the seat pedestal 90 is to be mounted into a receiving unit in the form of a receiving aperture or socket 102 centrally mounted in a flush mount deck or socket plate 100 which is, mounted on the deck 98 of a watercraft or the like. These type mounting devices are widely used in the marine industry, Upright support 14 could be connected directly to seat plate 92 or by using base 44 or to a pole mounting portion 49 as illustrated or the like. Many different types of similar mounting devices could be used to adapt upright support 14 for connection to many types of other separate structures including watercraft, chairs, tables or the like as mentioned elsewhere herein.
Turning to FIG. 8, therein is shown an alternative exemplary mounting structure for the present invention 10 using a conventional vehicle 106, e.g., a pickup truck as shown, wherein the upright support 14 is supported by a conventional receiver tube 104 of a trailer hitch using a draw bar insert portion 108 so that a user 60 can be shaded by canopy 16 of the present invention 10. Also shown are rods 18, 20 of the present invention 10. The lower end of the upright support 14 would be adapted to be supported on the vehicle 106 and in this example would include adapting the lower end of upright support 14 to connect to the draw bar insert portion 108. Also shown is an alternative exemplary mounting structure for the present invention 10 using a conventional chair 61 wherein the upright support 14 is supported by and attached to the chair by using a convention clamp 112 so that users could be shaded by the canopy 16 of the present invention 10.
Turning to FIG. 9, therein is shown an alternative exemplary mounting structure for the present invention 10 using a conventional table 110, e.g., a picnic table as shown, wherein the upright support 14 is supported by the table by using a convention clamp 112 so that users could be shaded by the canopy 16 of the present invention 10. Also shown are rods 18, 20 of the present invention 10. The upright support 14 would be adapted to be supported by the table 110 and in this example would include adapting the upright support 14 to connect to the table by using a clamp 112 or the like, or by having the lower end of the upright support be inserted into the ground as illustrated at 114 or by both.
Turning to FIG. 10, therein is shown an alternative embodiment of the present invention 10 showing the canopy 16 being extended or stretched between rods 18, 20 wherein the rods are each disposed on and extending along first and second sides or edges of the sheet of material of the canopy. The flexible rods 18, 20 are attached to an upper end of the upright support or stanchion 14 by having an end 32 of each rod pass through respective apertures 34, 36, 38, 40 provided in a removably secured end cap 116 on an upper end 118 of the upright support 14. An end of rod 18 extends or passes through aperture 34, 36 and an end of rod 20 passes through aperture 38, 40 as best shown in FIG. 2. Cap 116 is removably secured onto or over the upper end 118 of upright support 14 using a plurality fasteners 120, e.g., wing nuts or the like, which fasteners extend through apertures 122 which apertures extend entirely through the cap so that an end of the fastener can contact the outer surface of the upright support 14 which fasteners allow the cap to be attached to and removed from the upright support 14. This feature allows the cap 116 with canopy 16 disposed on rods 18, 20 to be attached to any type of suitable upright support 14 even a pre-existing upright support 14. Furthermore, the cap 116 with rods 18, 20 and canopy 16 may be more easily removed from the upright support 14 to make it easier to disassemble the rods and canopy from the upright support. Also shown are optional enlargements 124 being disposed on the free ends of rods 18, 20 which are used to removably secure the front ends of rods 18, 20 in apertures 36, 40 so the rods cannot accidently become dislodged or disassembled by pulling away from or through the apertures. In order to disassemble the. present invention 10, the optional enlargement 124 would first be removed. Enlargement 124 may be attached to the ends of rods 18, 20 in numerous ways such as by being threaded on to the rods. Other previously disclosed items may also be shown.
Turning to FIG. 11, therein is shown an alternative embodiment of the present invention 10 showing the canopy 16 being extended or stretched between rods 18, 20 wherein the rods are attached to a separate upper extension member 130 which is attached to the upper end 118 of the upright support 14 by means of a pivoting member 126 mounted onto the upper end 118 of the upright support 14 which allows the angle between the rods 18, 20 and upper extension 130 and the upright support 14 to be adjusted and which allows the rods 18, 20 to be pointed downwardly or upwardly if desired by a user; also, the angle between the canopy 16 and the horizontal can be easily adjusted. The tension on the pivoting attachment member 126 is adjustable by using a fastener 128, e.g., a wing nut or the like. An end of rod 18 extends or passes through aperture 34, 36 and an end of rod 20 passes through aperture 38, 40 as best shown in FIG. 2. Also shown are photovoltaic cells 72 disposed on canopy 16, as previously disclosed with respect to FIG. 5, for generating electrical current along with the negative and positive electrical output wires 74, 76 along with an electrical connector 132, e.g., a USB as shown herein, which electrical connector 132 could be powered by photovoltaic cells 72 or a battery 138 (see FIG. 2). Other previously disclosed items may also be shown.
Turning to FIG. 12, therein is shown an illustration of an exemplary electrical circuit diagram or schematic for the present invention 10, however, it is not represented that FIG. 12 discloses a circuit providing therein all of the possible functions disclosed in this application for the present invention 10. One skilled in the art would realize that numerous circuit diagrams different from FIG. 12 could also be used with the present invention 10. Shown in FIG. 12 are a lighting system including the light 134, a power supply being photovoltaic cells 72 or the like, electrical wiring harness 136, an alternative power source such as a battery 138 and battery recharger 142, and a suitable electrical switch 144 for controlling the light 134 and related components of the electrical circuit including electrical connector 132 and electrical outputs 74, 76. Photovoltaic cells 72 could be switched to provide energy for electrical connector 132 or for recharging the battery 138 or for both. Furthermore, the battery 138 could be switched to provide energy for the lights 134, the electrical connector 132 or both.
Turning to FIG. 13, therein is shown an alternative embodiment of the present invention 10 in use with a kayak 146 illustrating a user 60 driven pedal system 160 for driving a propeller 168 propulsion system. The present invention 10 may provide a monohull watercraft comprising a kayak 146 or like watercraft having a cockpit containing a seat located such that a hip of a user 60 is partially below an upper deck of the kayak, the cockpit also containing a set of rotatable of pedals 162 arranged in a rotating fashion around a crank axis, the kayak propelled by a propeller 168 that is driven via a linkage by the set of rotatable pedals. Also shown is a downwardly extending drive shaft member 164 operatively linked through a mechanical assembly 161 to rotatable pedals 162 which may include bevel gears. A first gear box 170 wherein bevel gears are located and transmit power and rotation at a substantially perpendicular angle to a generator 148 driven by the rotatable pedals 162 which connects to a second lower gear box 166 of a motor 172 having a propeller 168 thereon which propels the kayak 146. It would also be possible to drive the propeller 168 with many other type linkages, e.g., a flexible drive belt, such as a flat or round plastic belt or a chain, that transmits power from the pedals 162 to propeller 168. Bevel gears are known in the art and need not be described in detail here. One skilled in the art would understand that rotation of pedals 162 by the legs of user 60 results in transmission of power and rotation to the propeller 168. Electricity generated by generator 148 could be transmitted through electrical wiring harness 154 to a second battery 150 mounted in the kayak 146 or through electrical wiring harness 200 to the battery recharger 142. Electricity from the storage battery 150 could be transmitted through electrical wiring harness 156 to stern mounted auxiliary electrical motor 176 attached with a conventional mounting system 158 to the stern end of the kayak 146. Electrical motor 176 has propeller 178 mounted thereon for alternate propulsion of kayak 146 and which can be manually steered by the user 60 using tiller arm 174 in the conventional manner. Additionally, an optional rudder 155 is shown on the stern of the kayak 146. Additionally, electricity may be transmitted through electrical wiring harness 152 to battery 150 from battery 138 which battery 138 and related components have been previously disclosed with respect to FIG. 2. Energy from battery 150 can be used for many purposes, e.g., operating a cooler, radio, television, depth finder, cell phone, electric motor, lights and for many other uses as commonly done on watercraft. Other previously disclosed elements are also shown.
Turning to FIG. 14, therein is shown another embodiment being a pedaled kayak 146 illustrating user 60 driven flappers 184, 186 being a propulsion system propelled by the “penguin” like action of two transversely oscillating flexible flappers or sails 184, 186 which is fully disclosed in U.S. Pat. No. 6,022,249. As the force on the pedals 162 is increased, the less restrained end of the flapper or sail twists 184, 186 assume a propeller like shape. As the flappers or sails 184, 186 oscillate, they change pitch or shape upon reaching the end of their arcuate movement as they simultaneously reverse direction of movement at the opposite ends of their arcuate pathway. This sail action is somewhat similar to what happens when tacking in a sailboat in that the sails exert, in both of their directions of movement, a forward thrust component. The kayak 146 has propulsion means extending below the water line including a pair of flappers 184, 186 each adapted to oscillate through an arcuate path in a generally transverse direction with respect to the central longitudinal dimension of the watercraft 146. Means are operatively associated with the propulsion means for applying input force to the propulsion means whereby as input force is applied the flexible flappers 184, 186 can twist to form an angle of attack for providing forward thrust with respect to the longitudinal dimension of the watercraft 146 while moving in both directions along the arcuate path. The flappers 184, 186 twist to form an angle of attack for providing forward thrust with respect to the longitudinal dimension of the watercraft 146 while moving in both directions along the arcuate path. Kayak 146 has a cockpit 12 which contains a set of pedals 162 adapted to be pushed, first one and then the other, by the user's 60 feet. The kayak 146 is also provided with a rudder 155 and tiller 174. The pedals 162 are operatively connected by pedal shafts 182 to the flappers 184, 186 through a mechanical assembly referred to as a propulsion means 192 which include rotatable drums 188 and 190 which carry radially extending rigid masts which project in a generally downwardly direction so that they always remain in the water and do not contact the underside of the hull so that the masts support the sails or flappers 184, 186, respectively, at their leading edges. Each of the flappers 184186 are rotatable about its mast, so that the edge of the flapper opposite the leading edge can move from one side to the other with respect to the longitudinal center line of drums 188 and 190. This action results in both flappers 184, 186 exerting of forward force or push on the watercraft 146 in both directions of transverse movement of the flappers, providing propulsion to the watercraft 146. The generator 194 has a driving wheel 198 on its central shaft which is turned by the motion of the pedal shafts 182 by having a coupling rod 196 having its ends rotatably joined to the pedal shaft and the driving wheel as illustrated in FIG. 14. Therefore, as the user 60 operates the pedals 180 the generator generates electricity which is transmitted to the battery 150 just as illustrated with respect to FIG. 14. Other previously disclosed elements area also be shown.
Additional explanation of the presentation 10 is hereby provided with reference to all the figures wherein a lightweight canopy 16 for a boat 12 or other structure is disclosed which is fully adjustable up and down and rotatable in a 360 degree arc around the stanchion 14 using a line 54 which would allow a fisherman 60 underneath the canopy to cast while standing or sitting underneath the canopy. The canopy 16 also provides protection from sunrays and rain. The canopy 16 may be made of a sheet of any suitable flexible material such as canvas, or nylon-like material, for example polyethylene, and is supported by a pair of flexible, PVC, fiberglass or graphite rods 18, 20 about ⅝ inch in diameter being hollow or solid and the canopy may be attached to the rods using eyelets 30 with simple connectors 28 being run through the eyelets Land around the rods. The inherent resilience of the rods 18, 20 bias the flexible fiberglass rods away from each other providing an effective amount of tension for maintaining the canopy in a stretched out disposition between the rods wherein the rods are each bowed outwardly away from each other. Front ends 32 of the fiberglass rods 18, 20 are each passed through holes 34-40 placed in opposite sides of an upright support PVC pipe or post 14 or like type support post or stanchion which support post is mounted onto a boat 12 or the like at its lower end. The canopy 16 would be easy to use and relatively inexpensive to manufacture. Also, the solid flexible, fiberglass rods 18, 20 may be jointed at 22 so the system could be broken down and led for storage. Also, the rear ends of the flexible, fiberglass rods 18, 20 may be squeezed inwardly toward each other and tied to each other for securement using line 86 while the boat 12 is being operated at high speed in a forward direction. Also, in addition to watercraft 12, the canopy 16 could be mounted on many types of separate support structures such as picnic tables, trailers, pickup trucks, rear end of a vehicle, chairs, in the ground, a powered lift for hoisting workmen above the ground, or the like and there are many other applications for the present invention 10. Canopy 16 may be made of canvas or tarp-like material and may be waterproof PVC post 14 may have an inner member about 1½ inch in diameter and an outer member about 2 inch in diameter. Ferrules 22 and T-connectors 26 could be made of fiberglass or aluminum or the like. In the event that the rear ends of rods 18, 20 droop excessively downwardly due to the weight of the rods and canopy 16, apertures 34, 38 may be placed in upright support 14 so as to be slightly higher than apertures 36, 40 so as to place the rods in a slight upward angle relative to the horizontal so that the weight of the rods and canopy pull the rods and canopy downwardly back to the horizontal; also the angle of the rods may be adjusted with the optional pivoting attachment member 126.
A summary of the present invention 10 making reference to FIGS. 1-14 follows wherein a canopy 16 and upright support post 14 may be adapted or configured for being mounted on a separate structure such as a watercraft 12, in the ground 58, in a rod holder 47, on a vehicle 106, on a chair 61, or on a table 110 and includes an upright support post 14 haying upper and lower ends; first and second flexible rods 18, 20, each flexible rod having first, front 32 and second, rear ends; a first end of each flexible rod extending through an upper end of said upright support post, wherein each flexible rod is held firmly in apertures adjacent the upper end of the upright support post, wherein the flexible rods are substantially horizontally disposed and extend outwardly and away from the upright support post at an angle to each other in the range of 30 to 120 degrees and terminating at the seconds ends. The lower end of post 14 may be supported fixed in place on a structure with the upper end being rotatable with respect to the lower end, wherein the flexible rods are substantially horizontally disposed; and, a sheet of material having a first edge removably disposed on and attached to the first flexible rod and a second edge removably disposed on and attached to the second flexible rod so that the sheet of material forms a canopy extending between the first and second flexible rods and substantially from the first end of each flexible rod to the second end of each flexible rod. The sheet of material may include a solar cell fabric portion 72 to permit the production of electrical energy on a sunlit day including a barrel connector 77 or USB 132. A lighting system including a plurality of lights 134 may be disposed on the canopy 16 which light may be powered by an alternative power source such as battery 138 which battery may be recharged by the solar cell fabric portion 72. The flexible rods are constructed or configured so as to bias the rods away from each other providing an effective amount of tension for maintaining the sheet of material stretched out disposition. Wherein, the upright support post is adjustable in height using apertures 50 and a pin 52 and is rotatable in a 360 degree arc. Also, shown is a cross member 24 having first and second ends extending underneath the sheet of material 16 having the first end of the cross member connected to the first flexible rod and the second end of the cross member connected to the second flexible rod at 26. Wherein the first end 32 of each flexible rod 18, 20 is frictionally held in the plurality of apertures 34, 36, 38, 40 substantially perpendicular to the upper end of the upright support post 14. The angle formed between the rods 18, 20 (expected to be about 30 to 120 degrees) with respect to each other is effectively sized so that the rods become bowed enough to provide enough lateral tension to support the canopy 16 in a stretched out disposition. FIGS. 13, 14 illustrate embodiments of the present invention 10 wherein pedals 162 or 180 are driven by the user 60 so as to generate additional electricity using generator 148, 194 for various uses such as charging a battery 150 or driving electric motor 176 and for propelling a kayak 146 by either a propeller 168 or flappers 184, 186.
