The vehicle has a dashboard 115 and steering wheel 116 in front of the driver's seat 110. An overhead framework 120 formed of tubular members 124 extends over the seating region and includes a forwardmost tubular cross member 126 above and forward of the seating region 114. An accessory rail 128 is attached to the tubular cross member and accessories 130 extend therefrom including a visor and a camera. A soft top 132 wraps around the forwardmost tubular cross member 126 and extends rearwardly over the framework and is supported by and secured to the framework. The soft top providing a cover over the seating region.

Referring to FIGS. 3 and 4, further detail of the framework, soft top 132 and accessory attachment means are illustrated. The framework 120 is formed of steel tubing members 133 welded together, including rearward upright members 134, forward inclined members 135, cross members 137, and forward rearward members 138, all welded together. The framework further includes attachment flanges 140, 142 forwardly and rearwardly for attachment to the vehicle frame. See U.S. Pat. Nos. 8,695,746 and 9,527,532 illustrating three-wheeled vehicle frameworks and suitable attachment location for the overhead framework. These patents are owned by the owner of the instant application and are incorporated herein by reference for all purposes.

The soft top 132 may be formed of flexible waterproof fabric and has a forward edge that is looped over itself with a spacer placed therein and is stitched together to form an enlarged forward edge portion 145 as shown in FIG. 4. The enlarged forward edge portion 145 is retained in the accessory rail 128 as described in further detail below. The side edge portions 148 and rear edge portions 149 of the soft top may be secured to the framework by snaps, hook and loop material, straps or other means known in the art.

Referring to FIGS. 5-10, details of the accessory rail are illustrated. The accessory rail may be conveniently manufactured by extruding aluminum in the profile as best shown in FIGS. 9 and 10. The rail has an axis a1 that runs lengthwise and further has three functional portions radially positioned about the rail: an soft top anchoring portion 152 for the forward edge portion of the soft top; an interface portion 154 for engaging the tubular cross member; and an accessory mounting portion 156 with T-slot 157 for attaching accessories. The soft top anchoring portion 152 defining slot 153 extends slightly less than the overall length of the rail, as best illustrated by FIG. 8 allowing entry regions 159 for the enlarged forward edge portion 145 of the soft top. The cross member interface portion 154 extends the entire length of the rail as does the accessory mounting portion 156. Each of the three portions can be described as being C-shaped in the cross section or from the end view. The projections 161, 162 or legs of the C-shape of the soft top anchoring portion converging and being arcuate, the projections 163, 164 or legs of the C-shape of the tubular cross member interface portion diverging, and the projections 165, 166 or legs of the C-shape of the accessory mounting portion having an interior right angle and directly confronting one another.

In addition to each functional portion being circumferentially spaced about the rail, each functional portion has a “shared” portion of the accessory rail with the adjacent functional portions, providing an efficiency in use of material and an elegance in the design. The soft top anchoring portion 152 share portions of a common leg 162, 163 with the tubular cross member interface portion, the cross member interface portion and the accessory mounting portion share a common base portion 168, and the soft top anchoring portion 152 and the accessory mounting portion share a common base portion 170.

The rail will need minimal machining operations after extruding the rail and cutting it to size. The soft top edge anchoring portion will need the end portions machined off for providing the entry regions 159, a base portion 168 common to the cross member interface portion and the accessory mounting portion will need holes 172 drilled, and the confronting projections of the accessory mounting portion will need material removed for forming the enlarged T-slot access 174.

Referring to FIGS. 5 to 6B, further detail of the assembly of the accessory rail 128 to the tubular cross member is illustrated. In embodiments, the cross member interface portion 154 of the accessory rail has a pair of spaced contact surfaces 178, 179 on the two divergent projections 163, 164 that extend the entire length or substantially the entire length of the accessory rail. In embodiments, the surfaces are shaped to be conforming or for otherwise providing a minimal or non-damaging engagement. For example, in embodiments, the contact portions have no sharp edges, corners, or projections that engage the surface of the tubular cross member. The accessory rail may be secured to the tubular cross member with threaded fasteners, such as screws 182, 182.1 that are inserted through the holes 172 in the accessory rail and then is inserted into the tubular cross member 126. The holes 172 may be positioned at the enlarged access 174 to the T-slot 157. Referring also to FIGS. 13 and 14, in embodiments, the screws may be received by threaded metal inserts 185 that are inserted into holes in the tubular cross member 126 and which are clamped to the wall 186 of the tubular cross member 126 utilizing a tool, known in the art and not shown, that outwardly collapses the thin walled portion 187 to clamp the insert to the interior wall surface 188 and the exterior wall surface 189 of the cross member. Such inserts are known as rivet nuts and may have anti-rotation features. See U.S. Pat. Nos. 9,651,080 and 9,028,185, each of which are incorporated by reference herein. The accessory rail 128 may have counterbores 181, 183 at the holes 172 to allow the screws 182, 182.1 to seat flush or have a reduced head projection.

The threaded metal inserts 185 have an exterior head or flange 191 engaged with the exterior surface 189 of the tubular cross member and projecting slightly radially outward therefrom. The gap 193 between the interface portion projections 163, 164 accommodates the exterior head 191 of the threaded metal insert. The rail can be sized such that the screws 182 can be tightened to slightly flex the base portion and/or the two divergent projections 163, 164 to bring the base portion into contact with the head of the threaded metal insert.

Referring to FIGS. 4-10, the enlarged forward edge portion 145 of the soft top 132 is received in the slot 153 of the soft top anchoring portion 152 of the accessory rail 128. The edge portion 145 is sized for retention in the slot with the slot opening 194 being less than the thickness of the enlarged forward edge portion. The enlarged edge portion may be inserted into the slot by way of the entry regions 159, best shown on FIG. 8.

Referring generally to FIGS. 2-10, the accessory mounting portion 156 of the accessory rail 128 may be configured as a T-slot 157, with the projections or legs 165, 166 defining the slot and the slot opening 197. In embodiments, the T-slot extends the entire length of the rail 128 or substantially the entire length of the rail. Referring additionally to FIGS. 11 and 12, the accessory mounting portion provides a threaded, position adjustable connection point 200 by way of threaded fasteners 204, which may be configured as a T-nut 206 or as a bolt 208 with a square head 209. The threaded fasteners cooperate with and slidingly fit into the T-slot 157 such as at the T-groove access 174. FIG. 5 illustrates the connection point 200 configured as male threaded member 211, part of the bolt 208 that provides the adjustable positioning of accessories.

Referring to FIG. 10, an end view of the accessory rail 128 and a generic accessory 220 are shown in isolation, that is, not connected to the tubular cross member for illustration purposes. A T-nut 219 slidably positioned in the T-slot 157 provides a threaded female connection. An accessory 220, having an accessory mounting bracket 222 with a hole 223 is positioned at the T-nut and in contact with the accessory rail and a manual attachment screw member 230 with a male threaded shaft 234, a flange 236, and a manual handle 238 extends through a hole 241 in the accessory mounting flange and threadingly engages the T-nut. By manual rotation of the handle, the flange clamps the legs 165, 166 of the accessory mounting portion between the T-nut and the flange, thereby locking the position of the accessory in place. Positional adjustment can be accomplished by slightly loosening the manual attachment screw member and sliding the T-nut and accessory axially on the accessory rail to a desired location where the screw member is again tightened.

Similarly, as illustrated in FIG. 5, the bolt 208 with the square head can provide a threaded male member projecting from the accessory rail to which the accessory bracket 222 may be attached and retained with a nut.
