BACKGROUND OF THE INVENTION
This invention relates to coverings and awnings for golf carts. A standard golf cart has an area for stowage of golf clubs and other equipment at the rear of the cart. While the cart's roof covers persons riding in the cart, it leaves the equipment in the stowage area uncovered. Golfing equipment can be very expensive, and it is undesirable for it to get wet because of rain. As such, a cover extending over the rear stowage area of the cart is desirable. However, ready access by a golfer to his equipment is essential, so the cover should not obstruct the golfer's ability to reach for clubs as needed. Further, if rainy conditions are not present, the cover is not needed and must be moved out of the way. There exist retractable covers that extend over the cart's stowage area, but they often do so in a cumbersome fashion. While some covers, when deployed, may do an adequate job in keeping rain off the equipment, they do not fold away in a neat, compact fashion when retracted after use. Still other disadvantages found in the prior art designs include inconvenient mounting arrangements for attaching the cover to the golf cart, supporting frameworks which are cumbersome and unduly complicated and which do not adequately support the fabric, and inadequate mounting arrangements for securing the cover to the golf cart at or near the canopy top thereof. This is especially a problem in that there are several major manufacturers of golf carts who have varying arrangements for their canopy tops, some of which have curvilinear edges not readily suited to alignment with a standardized bracket member. Furthermore, as there is concern in providing clearance for the removal and replacement of golf clubs from the golf bags as they are carried near the rear portion of the golf cart, these canopy tops are generally shortened and do not extend into the area immediately above the golf bag compartment. This then provides a challenge for the cover in that it must conveniently extend to provide adequate rain cover for golf bags but yet be readily collapsible up and out of the way of the bags and their clubs. As a result, care must be taken in designing and implementing a supporting framework. In other words, the framework must be large enough to allow for it being extended a substantial distance behind the rear portion of the top assembly which necessarily makes it “substantial” having some degree of relative size which increases its weight and complexity. With this added weight and complexity, mounting and operation become important issues as the cover must give the appearance and feel of a quality product in this luxury setting.

DETAILED DESCRIPTION
The following detailed description illustrates the invention by way of example and not by way of limitation. The description clearly enables one skilled in the art to make and use the invention, describes several embodiments, adaptations, variations, alternatives, and uses of the invention, including what is presently believed to be the best mode of carrying out the invention.
The awning attachment of the present invention, which is generally indicated by the reference numeral 10, is shown in FIG. 1. It is similar to the FIG. 1 shown in application Ser. No. 10/316,321, hereby incorporated by reference. It is comprised of a framework 12 which supports a fabric covering 14. Framework 12 is comprised of a series of U-shaped rib members 16, 18, 20 and 22, each having ends 16′, 16″, 18′, 18″, 20′, 20″, 22′ and 22″, respectively. While additional, or fewer, rib members may be employed, four rib members provides the optimum number to adequately provide support for the fabric covering and give it a pleasing, gently arcuate shape. The respective rib member ends are connected together by bolts or pins 24 and 26, as shown in FIGS. 1 and 3, to create common pivot points 25 and 27, respectively, by which the rib members may be moved relative to each other. Bushing 28 are provided along bolts 24 and 26 between the rib member ends to provide adequate separation thereof to facilitate relative movement of the rib members when fanned out. A sufficient amount of fabric covering 14 is provided to enable the awning, when deployed, to extend arcuate from the rear edge section 30 of the roof of the cart to a point slightly beyond the rear edge of the cart, and to a level approximately even with the seats of the cart, so as to effectively cover the top of a golf club bag 32 held upright in the storage compartment as shown in FIG. 4.
Sleeves are disposed on the forward and rear edges and underneath side of fabric cover 14 by sewing or the like to receive the rib members as shown in FIGS. 1 and 2. The sleeves allow a certain freedom of movement of the fabric cover along the rib members to facilitate deployment and retraction of the awning. Sleeve 50 is formed around the perimeter front lateral edge of fabric cover 14 and receives arms 34 and cross piece 36 of rib member 16. Sleeves 52 and 54 receive arm 38 and cross piece 40, respectively, of rib member 18. A corresponding sleeve 52 on the opposite interior side of fabric 14 receives the other arm 38. Similarly, sleeves 56 and 58 receive arms 42 and cross piece 44, respectively, of rib member 20. Sleeve 60 is formed around the perimeter rear lateral edge of fabric cover 14 and receives arms 46 and cross piece 48 of rib member 22.
Each successive rib member after the first top rib member has an incrementally shorter dimension with respect to both its length and width so that the entire framework may lie substantially flat in a nesting relationship when in the closed retracted position shown in FIG. 6. As further shown in FIG. 1, rib member 16 comprises arms 34 and cross piece 36. Rib member 18 comprises arms 38, which are around ½ to one inch shorter than arms 34 of rib member 16, and cross piece 40, which is around one to two inches shorter than cross piece 36 of rib member 16. Likewise, rib member 20 comprises arms 42 and cross piece 44, which are respectively around VD to one inch shorter than arms 38 and around one to two inches shorter than cross piece 40 of rib member 18. Further, rib member 22 comprises arms 46 and cross piece 48, which are respectively around ½ to one inch shorter than arms 42 and around one to two inches shorter than cross piece 44 of rib member 20. The dimensions may vary due to the thicknesses of the rib members and fabric cover 14 held between the rib members. This arrangement allows each successive rib member to be nested within the forwardly preceding rib member in a planar relationship. Rib members 16-22 substantially flat in cross section which facilitates their side-by-side placement at pivot points 25 and 27 and also allows the nesting relationship shown in FIGS. 3 and 6. Bushing 28 keep the rib members spaced apart to provide room for the fabric sleeve material sandwiched between the rib members.
The awning attachment is fitted on to a golf cart as shown in FIG. 4. The forward edge of the frame structure, at the top edge of rib member 16, is connected to the underneath side of the rear section 30 of the cart's roof. Such connection can be made by providing drill holes in both the rib member and the roof to allow screwing or bolting the rib member directly into the roof section, or by any other appropriate connection means known to those skilled in the art. Preferably, the rib member should lie flush with the rear edge of the roof so that the awning remains as unobtrusive as possible. Due to the various different manufacturers of golf carts, and the various different roof designs produced by each, it may be difficult to attach the rib member flush up against the edge of the roof. This is because some roof edges may be non-rectilinear, and may have curved edges. In such instances, the rib member can not adjoin the roof edge in an aesthetically pleasing way, and, further, may not even be capable of being directly attached to the roof edge.
To provide a surface for attachment of the awning at the rear edge of the cart roof, an extended transition plate member 80 against which rib member 16 may be secured is supplied. Plate member 80 is held in place by U-shaped top mounting bracket 84 as shown in FIGS. 11 and 12. Bracket 84 is secured to the underneath side of the roof of the golf cart which typically forms an interior flange 85 around the rear edge 30 of the roof. The shape of bracket 84 may be modified to accommodate the perimeter shape of the roof, which may be rectilinear or have rounded edges. Roof flange 85 can be provided with a plurality of apertures 86 around its perimeter, while bracket 84 may be provided with correspondingly placed apertures 88 to secure bracket 84 to the roof flange 85 by bolting or other appropriate fastening methods as shown in FIG. 11. Plate member 80 has a flange 82 at its forward end for connection with bracket 84 as shown in FIG. 12. Bracket 84 is optimally dimensioned such that flange 82 will be held between bracket 84 and roof flange 85.
The frame is further secured to the cart's upright, vertical support posts 62 and 64 through mounting clamps 66 and 68. These mounting clamps, as shown in FIG. 5, each comprise a metal strap 70 having a clamp 72 for engaging the cart's support post 62 or 64. Clamp 72 may comprise an open faced C-shaped channel having inwardly biased edges for holding support post in tight engagement. Alternately, a clamp having a tightening fastener, such as a threaded C-clamp, may be used. Further still, a clamp that surrounds the vertical post may be employed, and can be configured with a square or round opening to accommodate the appropriate geometrical cross section of the support post. Mounting clamps 66 and 68 each have an end 74 for mounting at pivot points 25 and 27 for the rib members of framework 12 as shown in FIG. 3. It is to be understood that the configuration of the vertical support posts of carts of different manufacturers may vary, with the posts being set wide in some cart models and set narrow in other cart models. As such, the distance of the pivot points 25 and 27 to the cart's supports will vary. To accommodate such different dimensions, the mounting clamps may be provided with different lengths of straps 70.
The frame may alternately be mounted to the vertical support posts of the golf cart from a position on rib member 16 remote from pivot points 25 and 27. In such cases, connecting metal straps 70 would be moved from the pivot point (as shown in FIG. 3) and instead be positioned along a median portion of rib member 16 as shown in FIGS. 8 and 9. This particular positioning of strap 70 on rib member 16 further provides a greater degree of overall stability to the attached awning, as pivot points 25 and 27 are sufficiently stable due to the interconnection of the rib members and do not need supplemental stabilization. Strap 70 may be simply connected to rib member 16 by bolting 92 or other appropriate fastener. The remote end 90 of strap 70 may be fastened to the cart's vertical support posts 62 and 64 by direct bolting, or may be provided with a clamp 93 for engagement around the support post. To accommodate the different spacing of the vertical support posts on carts of different manufacturers, strap 70 may be configured with an offset angle 94 as necessary to reach to a vertical post set wider than the awning as shown in FIG. 13. Likewise, the offset angle can be configured to connect to a vertical post set narrower than the awning.
Alternatively, the rear section 30 of the cart's roof may include an integral transition member 110 against which the awning may be secured, as shown in FIG. 23. To secure the awning, the rib member 16 connects to the underneath side of the integral member 110 by providing drill holes in both rib member 16 and the integral member 110 to allow screwing, bolting, or riveting, the rib member directly into the roof section, or by other appropriate connection means known to those skilled in the art. If supplemental support or stabilization is desired, mounting clamps 66 and 68 as previously described and shown in FIG. 5 may be used. In addition, metal straps 70 as previously described and shown in FIGS, 8, 9, 13, and 14 may be used.
To hold the loose fabric material of cover 14 in a neat bundle when the awning is in the closed, retracted position, a gathering flap 76 is provided on the top section of cover 14. FIG. 1 shows flap 76 extending along the substantial width of cross piece 36 of rib member 16, being secured to the fabric by sewing or the like along that end. The free end is provided with snaps or hook and loop fastening material. When the awning is in the open, deployed position, gathering flap 76 lies loosely on the top of fabric covering 14 on the back of the awning. It is not long enough, however, so that it dangles below the rear bottom edge of the awning. When the awning is folded up into its closed, retracted position, gathering flap is wrapped around the nested rib members and secured by its snaps or hook and loop fastening means to corresponding fastening means on the forward lateral edge of the framework of the awning or to the underneath side of the roof of the cart as shown in FIGS. 6 and 7.
When the awning is attached to the golf cart by using extended transition plate member 80, the orientation of gathering flap 76 may be reversed, by securing the base end 91 underneath plate member 80 and configuring flap 76 to be drawn around the nested rib members and secured to the top of plate member 80, as shown in FIG. 10, by appropriate fastening means previously described. The gathering flap 76 may be constructed to be removable from its seducement under plate member 80 using various fastening means, such as a zipper, hook and loop fastening means, etc. For a reinforced connection, flap end 91 may be provided with a dowel or webbing member 96 at its edge, and a C-channel 97 may be secured underneath plate member 80 to slidably receive the dowel or webbing member of flap end. A stiffener member 98 may be provided at the remote end of flap 76 to provide a certain amount of weight and rigidity so the flap end will be resistant to curling and be made easier to handle. Also, a fastener 99 may be provided at the remote flap end so that flap 76 may be doubled back on itself when not in use.
By having the gathering flap extend the substantial width of the framework, it avoids unsightly bulging out of material that would be present if narrow gathering strips were instead used. As an additional advantage, the wide gathering flap allows for a clear vinyl pocket for printed material to be placed therein which presents a useful marketing tool for advertisers during golf tournaments.
Referring to FIGS. 14 and 15, a zipper 100 or hook and loop material may be provided along an edge of the fabric cover for the selective placement of a fabric panel 102, as desired for shielding from view the connecting metal straps 70 which may be used to support the awning cover from the vertical support posts 62, 64. Furthermore, in the arrangement as shown in FIGS. 14 and 15, the transition plate 80 may not be secured to the rear section 30 of the cart's roof and instead may merely have an upstanding flange 104 with a protective cushion covering 106 for resiliently engaging the lip of the golf cart top 30. In this arrangement, the straps 70 provide the sole means of support for the awning cover from the vertical posts 62, 64. Although an arrangement shown in FIGS. 14 and 15 indicating that the transition plate 80 and its upturned flange 104 may be conveniently urged against the canopy top 30 of the golf cart, this need not be the case as the straps 70 may merely be repositioned to provide a space between flange 104 with cushioning member 106 and the golf cart top 30.
While the arrangements in FIGS. 14 and 15 do not require the transition plate 80 to be secured to the rear section 30 of the cart's roof, the arrangement does not preclude securing the transition plate 80 to the rear section 30 either. As shown in FIG. 19, the transition plate 80 and the upstanding flange 104 may be secured to the rear section 30 of the cart's roof with a suitable fastening means, such as bolts or rivets.
As shown in FIG. 16, the awning cover 10 of the present invention is readily adaptable to being used with a total enclosure as is presently being marketed by others and which provides an all weather enclosure for the golf cart.
As shown in FIGS. 17 and 18, bracket 84 may be provided in different form to suit the canopy top arrangement as used by different manufacturers. In the arrangement as shown in FIG. 17, top mounting bracket 84 conveniently mounts with the existing pair of bolts at either side thereof to the vertical support posts 62, 64 and at their inner surfaces. On the other hand, as shown in the arrangement of FIG. 18, top mounting bracket 84 may conveniently fit between vertical support posts 62 and the plastic canopy cover 30 and, again, be held in place by bolted connections as shown. In either arrangement, top mounting bracket 84 provides a convenient flat planar surface against which the upturned flange 82 of transition plate 80 may be readily abutted and mounted with its own mounting bolts to provide a secure connection between the awning cover and the supporting framework of the golf cart top assembly.
Use
The retractable awning of the present invention provides a useful attachment to the rear of a golf cart to keep equipment dry during rainy periods. It is very simply employed by pulling apart the rib members in fan-like fashion to create the arcuate structure of the awning. When a golfer needs to access her equipment and reach for a club, she need merely raise the edge of the awning to a sufficient degree to be able to reach in to the golf bag. When the rainy conditions no longer exist, the framework is simply pivoted into its closed retracted state. The nesting arrangement of the rib members allows for a neat, compact arrangement. Gathering flap 76 is then wound around the rib members to neatly bundle the fabric material. The awning of the instant invention, however, need not only be used for rainy conditions; it can also be used as a screen to protect the cart occupants from the rays of the sun and or very windy days. Thus, the awning can be kept in its open deployed state all the time. If desired, a window 78 may be formed in the rear of the awning using transparent plastic or the like and a pocket or sleeve with transparent window may be provided for the ready insertion of advertising or signage. Also if desired, the rear of the awning may also be used for advertising or other indicia. As shown in FIG. 20, indicia may be placed on the fabric cover 14 along the rib member 22.
As shown in FIGS. 20-23, awning 10 may include a tab 112 positioned for engagement by an operator to pivot and secure the awning between the extended position and the retracted position. One end of the tab 112 is attached to the cover 14 by sewing or other suitable means known to those skilled in the art. The opposite end of the tab 112 is provided with a fastener 114, such as Velcro@, snaps, or hooks that removeably attaches to the transition plate 80, as shown in FIGS. 20-21, or the integral element 110 as shown in FIG. 23. In operation, the operator pulls upwardly on the tab 112 until the awning 10 is in the retracted position and secures the tab 112 to the transition plate 80, thereby securing the rib members 16-22 in the nesting arrangement. To extend the awning 10, the operator unsecures the tab 112 from the transition plate 80 and pulls downwardly on the tab 112 until the awning 10 is in the extended position. It should be noted that the action of moving and securing the awning 10 with the tab 112 may be accomplished all in one motion using one hand, allowing for an easy and efficient use of the awning 10. The action of unsecuring and moving the awning 10 with the tab 112 may also be accomplished all in one motion using one hand.
Alternatively, the tab 112 may be attached to the transition plate 80, roof 30, rib member 16, sleeve 50 or other appropriate areas and removeably attached to the fabric cover 14 surrounding rib member 22, or other appropriate area. In this embodiment, the operator pivots the awning to the retracted position and secures the tab 112 to the rib member 22. To extend the awning 10, the operator unsecures the tab 112 from the rib member 22 and pivots the awning 10 to the extended position.
In yet another embodiment, multiple tabs may be used.
In another alternate embodiment shown in FIG. 24, a latch 116 is positioned for engagement by an operator to pivot and secure the awning between the extended position and the retracted position. The latch 116 includes a first member 118 attached to the transition plate 80 and hingedly attached to a second member 120 with a spring hinge 122. The second member 120 pivots back and forth to secure and unsecure the awning 10. The spring hinge 122 biases the second member 120 downwardly to secure the rib members 16-22 in the nesting arrangement. In operation, the operator pulls upwardly on the second member 120 until it is clear of the awning, and then pulls the awning 10 downwardly to the extended position. To close, the operator pulls the awning 10 upwardly to the retracted position and the second member 120 pivots downwardly, thereby securing the rib members 16-22 in the nesting arrangement. If desired, the tab 112 can be used in conjunction with this arrangement.
Changes can be made in the above constructions without departing from the scope of the invention, it is intended that all matter contained in the above description or shown in the accompanying drawings shall be interpreted as illustrative and not in a limiting sense.
