FIELD OF THE INVENTION
The present invention relates to boat shades generally and, more particularly, to a method and/or apparatus for implementing a removable and/or collapsible sunshade.
BACKGROUND OF THE INVENTION
Conventional boat sunshades, such as bimini tops, that are available in commercial markets are often designed for large boats. Such shades typically have large and cumbersome aluminum frames. Such frames do not disassemble easily and only allow for permanent mounting. A permanently mounted frame does not work well on smaller boats, such as inflatable boats or hard shell rowboats.
It would be desirable to implement a sunshade for a boat that would allow a consumer to bring along the sunshade in the boat and assemble the sunshade when needed. It would also be desirable to implement a sunshade that swivels down and out of the way of passengers without needing to be detached from a boat.
SUMMARY OF THE INVENTION
The present invention concerns an apparatus comprising a first pivot, a second pivot, a first pole, a second pole and a fabric portion. The first pivot may have a first insert and a second insert. The second pivot may have a third insert and a fourth insert. The first pole may have a first end connected to one of the first or second inserts and a second end connected to one of the third or fourth inserts. The second pole may have a first end connected to the other of the first or second inserts and a second end connected to the other of the third or fourth inserts. The poles may be arranged to create a gap between the first and second pivots. The fabric portion may be connected between the poles to cover the gap.
The objects, features and advantages of the present invention include providing a removable sunshade for a boat that may (i) be disassembled while either in the boat or out of the boat, (ii) be stored in a bag, and/or (iii) be used in a small boat, such as an inflatable or hard shell rowboat.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
The present invention concerns a sunshade or bimini top for a portable boat, such as an inflatable boat. The present invention may have two collapsible poles that normally fold down along with a fabric top to fit into a small waterproof bag. The present invention may be used to protect a consumer from harmful ultra violet (UV) rays by providing shading from direct sunlight. The present invention may be particularly useful in inflatable and aluminum portable type boats. The sunshade may be disassembled in the boat or out of the boat and may be stowed away in a small bag for easy convenience.
Referring to FIG. 1, a diagram of a system 100 is shown in accordance with a preferred embodiment of the present invention. The system 100 generally comprises a cover (or sunshade) 102 connected to a boat 104. The cover 102 generally comprises a number of pivots 106a and 106b, a number of poles 108a and 108b, a fabric portion 110, a number of straps 112a-112d, and a number of rings 114a-114d. In one example, the poles 108a-108b may be made of fiberglass. However, other materials may be used accordingly to meet the design criteria of a particular implementation. In general, the poles 108a-108b are made from a light material that is flexible enough to bend, yet sturdy enough not to break. In one example, the poles 108a and 108b may each be made as a single piece. In another example, the poles 108a-108b may be made as a number of smaller sections connected by a number of ferrules 116a-116n. The ferrules 116a-116n may be implemented, in one example, as aluminum pieces configured to hold together the various sections of the poles 108a-108b. 
The poles 108a and 108b normally slide through a channel 116a (or 116b) sewn into the fabric portion 110. While the channels 116a-116b are shown along the length of each side of the fabric portion 110, one or more smaller channels may be formed for each of the channels 116a-116b. For example, a small channel may be implemented periodically (e.g., every inch, every 3 inches, etc.) to hold the poles 108a-108b. Each end of the poles 108a and 108b may be secured to the pivots 106a-106b. For example, the pole 108a has a first end connected to one of a first or second inserts in the pivot 106a and a second end connected to one of a third or fourth insert in the pivot 106b. The pole 108b has a first end connected to the other of the first or second inserts of the pivot 106a and a second end connected to the other of the third or fourth inserts of the pivot 106b. 
The pivots 106a and 106b may be attached to the boat 104. In one example, the pivots 106a-106b may be glued to the boat 104. However, the pivots 106a and 106b may be secured in other ways (e.g., with hook and loop fasteners, such as VelcroTM, with snap hooks, etc.).
The straps 112a-112n may be adjustable. The straps 112a-112n may be made of nylon, or another type of strong, yet light weight material. In one example, the length of each of the straps 112a-112n may be adjustable through a slip fastener or other type of adjustment. Each of the straps 112a-112n may be connected between the fabric portion 112 and one of the rings 114a-114d. The rings 114a-114d may be attached to the boat 104 with glue, similar to how the pivots 106a-106n are attached to the boat 104. For a metal or wooden boat 104, the rings 106a-106n may be screwed to the boat 104. In particular, the rings 114a-114n may be secured to a patch that may then be secured to the boat 104 (to be described in more detail in connection with FIG. 2).
The poles 108a and 108b may be positioned to create a gap between the first pivot 106a and the second pivot 106b. In particular, the pole 108b is shown positioned towards the back of the boat 104 while the pole 108a is shown positioned towards the front of the boat 104. The portion between the pivot 106a and the pivot 106b on one side and the pole 108a and the pole 108b on another side creates a gap. The fabric portion 110 may be formed to cover the gap and create the shade portion of the top 102. The fabric portion 110 may be made of a suitable boat top material. For example, a material with UV protection may be used. A material that may also be water repellant and/or mildew resistant may also be used.
Referring to FIG. 2, a more detailed diagram of the pivot 106a is shown. The pivot 106a generally comprises a mounting portion 120, a base portion 122, a pin 124, a securing portion 126, and a number of receptacles 128a and 128b. The mounting portion 120 may be a flexible material, such as rubber, or other appropriate material. The mounting portion 120 may be in the shape of a patch, and may be connected to an inflatable boat the way a patch would be connected to an inflatable boat. For example, inflatable boat repair glue may be used to secure the mounting portion 120. For example, a flexible glue, such as a one-part (or two part) glue may be used. The patch 120 may be screwed to frame of a non-inflatable boat 104.
The pole 108a and the pole 108b attach to a respective one of the receptacles 128a and 128b. The safety pin 124 securely holds the pole 108a and the pole 108b in place. The securing portion 126 may be used to secure the safety pin 124. The pivot 106a and the pivot 106b are normally positioned on the boat 102 in order to maximize sun protection. For example, the pivot 106a and the pivot 106b are normally positioned somewhere on the center portion of the boat 102.
Referring to FIG. 3, a top view of the system 100 is shown. FIG. 3 shows six attachment points (e.g., 106a, 114a, 114b, 114c and 114d). The attachment points are normally selected to provide maximum stability. For example, the ring 114a and the ring 114b are normally positioned in a generally V-shaped configuration around a connection point to the top 110. Similarly, the rings 114c and 114d are normally positioned in a generally V-shaped configuration on the opposite portion of the top. The poles 108a and 108b are shown extending down and attaching to the pivots 106a and 106b. The straps 112a-112d are shown extending down to the rings 114a-114d. The straps 112a-112d allow the top to be tightened for stiffness.
In one example, the side of the straps 112a-112d that are connected to the top 110 may have a looped end that surrounds the cavity sewn into the top 110. The looped end may allow the respective pole 108a or 108b to be inserted through the loop, providing additional support. The additional support may help reduce tearing of the top 110.
The system 100 may also include a portion 130a and a portion 130b. The sections 118a-118b may be secured to the boat 104 and may each include a respective strap 132a-132b. The straps 132a and 132b may be used to secure the top 102 when in a collapsed position. The straps 132a and 132n may be either tied off, or secured with VelcroTM or other fasteners.
The length of the pole 108a and the pole 108b may be selected to provide sufficient height to said top 110. For example, if a tall height is desired, the pole 108a and the pole 108b may be selected to be longer than if a shorter height was desired. In one example, the pole 108a and the pole 108b may be implemented in a number of shorter sections that are assembled to create the full length of either the pole 108a or the pole 108b. In such an arrangement, additional sections may be added to increase the length of the pole 108a or the pole 108b. Additionally, a string (or other type of wire, cord, etc.) may be added within a hollow portion of each section of the poles 108a-108b to aid in the assembly of the pole 108a or the pole 108b. 
The sunshade system 100 may be assembled with a minimum effort. First, a user may secure the pivot pieces 106a and 106b to the boat 104. Next, a user may secure the rings 114a-114n to the boat 104. A user may then insert the pole 108a into a first channel of a fabric piece 110. The user may then insert the pole 108b into a second channel of the fabric piece 110. The user may then insert the pole 108a between the first pivot 106a and the second pivot 106b. The user may then insert the second pole 108b between the pivot 106a and the pivot 106b. The user may then install the strap 112a and the strap 112b between a near portion of the pole 108a and a respective one of the ring 114a and 114b. The user may then install the strap 112c and the strap 112d between a near center portion of the pole 108b and a respective one of the rings 114c and 114d. The straps 112a-112n may be tightened after being installed.
While the straps 114a-114n are normally installed at or near the center of the respective poles 108a and 108b, other configurations may be possible. For example, each strap 112a-112d may be installed at a different portion of the respective poles 108a and 108b. While a generally symmetrical configuration may be implemented, other non-symmetrical implementations may be implemented to meet particular design criteria.
Referring to FIGS. 4A-C, the top 110, the pole 108a, the adjustable straps 112a-112d and a bag 160 are shown. In one example, the bag 160 may be made of nylon. However, other flexible materials may be used. Materials that allow water or moisture to escape may also be used. Such materials avoid mildew or mode buildup when the top 102 is being stored. The bag 160 may have a string 162 that may be used to secure the bag 160.
Referring to FIG. 5, a system 200 is shown illustrating an alternate embodiment of the present invention. The system 200 normally connects a pole 108a′ between a pivot 202a and a pivot 202b. A pole 108b′ is normally connected between a pivot 202c and a pivot 202d. The pivots 202a-202d may each be configured to hold one end of one of the poles 108a′ or 108b′. The pivot 202a and the pivot 202b may be secured to the boat 104′ in different locations from each other. Similarity, the pivot 202c and the pivot 202d may be secured to the boat 104′ in different locations from each other. By spacing the pivots 202a-d, a larger top portion 110′ may be implemented.
Referring to FIG. 6, a more detailed diagram of the pivot 202a is shown. The pivot 202a may be secured to the boat in a similar manner as the pivots 106a and 106b. The pivot 202a may have a hole 204 that may be used to secure one end of one of the poles 108a′ or 108b′. In order to provide a secure connection, the end of the pole 108a′ or 108b′ that is secured normally has a hole. A pin (not shown) may be used and may be positioned between the hole in the pole 108a′ or 108b′ and the hole 204.
Referring to FIG. 7, a system 300 illustrates another alternate embodiment of the present invention. The system 300 normally rotates the poles 108a′′ and 108b′′ 90 degrees with respect to the boat 104′′. By rotating the poles 108a′′ and 108b′′, an alternate configuration may be formed. The straps 112a′′-112d′′ may be used to provide stability to the system 300.
While the invention has been particularly shown and described with reference to the preferred embodiments thereof, it will be understood by those skilled in the art that various changes in form and details may be made without departing from the spirit and scope of the invention.
