Cart canopy system

Abstract

The invention may be embodied in as a canopy system for a vehicle, such as a golf cart. The invention may include nested support members and/or a housing.

Description

FIELD OF THE INVENTION

The present invention relates to canopies for vehicles, such as golf carts.

BACKGROUND OF THE INVENTION

Some vehicles, such as golf carts, have a storage area located behind the driver's seat where equipment, such as golf clubs, may be kept. A protective canopy may be attached to the cart to shield the storage area and its contents from rain and sun. An example of such a device is shown in U.S. Pat. No. 4,830,037. In the prior art there are retractable awnings having a plurality of U-shaped rib members and a fabric cover. The U-shaped rib members have ends terminating at a common pivot point. Such a design places high forces on the pin used to provide the common pivot point, and results in frictional forces between the rib members, which make the awning difficult to deploy and store and may reduce the useful life of the awning. There is therefore a need for awning systems which reduce the forces placed on pivot pins and for awning systems which reduce or eliminate the frictional forces between rib members.

The prior art also includes designs in which each successively adjacent rib member is dimensioned slightly less than its preceding rib member to allow nesting of all the rib members in a common plane when the awning is in its retracted position. In order to allow for nesting and also provide proper coverage for the storage compartment of the cart, the prior art also discloses a transition plate extending between the cart roof and one of the rib members. Although there are advantages to an awning in which the rib members may nest with each other, the transition plate increases the cost associated with providing the awning, requires relatively precise positioning of the awning with respect to the cart roof, and complicates the design. Consequently, there is a need for nestable awning systems which do not require a transition plate.

The prior art also discloses gathering flaps, which are used to wrap around the rib members in order to hold the rib members in the nested position. Such flaps are unsightly, particularly when the awning is deployed and the flap is not in use. Even when the flap is in use, the flap does little to minimize the aesthetic degradation resulting from having an unused awning attached to the cart. Further, such flaps are difficult to use since the user must hold the rib members in the nested position with one hand and secure the flap with the other hand while leaning over the storage compartment of the cart. Placing the user in such a position may also present a safety issue, particularly when the surface the user is standing on is wet or consists of material which may shift, such as loose gravel. Therefore, there is a need for awning systems that do not require a flap to hold the awning in the undeployed position.

SUMMARY OF THE INVENTION

The present invention includes a canopy system, which may be used to shield a storage area. The invention may be embodied as a canopy system for a vehicle in which there is (a) a first support member having a first end, a second end, and a middle portion, the first end being pivotally supported from the cart and being pivotable about a first axis, (b) a second support member having a first end, a second end, and a middle portion, the first end being pivotally supported from the cart and being pivotable about a second axis, the second axis being different from the first axis, and (c) a canopy supported from at least one of the support members. For example, the canopy may be supported from one of the middle portions. The canopy system may be designed so that when the canopy is not in a deployed position, the first support member and the second support member are in a nesting relationship.

The invention may also be embodied as a canopy system for a vehicle in which there is (a) a support member, (b) a canopy supported by the support member, and (c) a housing having an opening. The opening may be designed so that at least a portion of the support member travels through the opening when the canopy is moved from a deployed position to a stored position. Alternatively, or in addition, the opening may be designed so that the canopy extends through the opening.

A method according to the invention may include (a) providing a first support member which is pivotable about a first axis, (b) providing a second support member which is pivotable about a second axis, the first axis being different from the second axis, (c) providing a canopy supported from the first support member, and (d) moving the first support member so as to pivot the first support member about the first axis from a first position in which the support members are in a nesting relationship with each other, to a deployed position in which the canopy is extended over a portion of the vehicle.

DETAILED DESCRIPTION OF THE INVENTION

The invention may be embodied as a canopy system for a vehicle 10, such as a golf cart. In that embodiment, there may be a first support member 13 and a second support 16 member. FIGS. 1A, 8 and 14 are examples of such a canopy system. Additional support members 19 may also be included. For example, FIGS. 2 and 5 each show four support members 13, 16, 19. Each of the support members 13, 16, 19 may have a first end 22 and a second end 25. A middle portion 28 may also be provided to extend between the first end 22 and the second end 25. Each of the first ends 22 may be pivotally supported from the cart 10. One or more of the support members 13, 16, 19 may have a substantially U-shape.

An example of a support member 13, 16, 19 is shown in FIG. 1B. In an embodiment of the invention, the support member 13, 16, 19 has a width W that is between 3 and 6 inches. It has been found that gathering of the canopy 49 is made easier when the width W is in this range. The thickness T may be made less than the width W.

The first end 22 of the first support member 13 may be pivotable about a first axis 31. The first end 22 of the second support member 16 may be pivotable about a second axis 34. FIGS. 3, 6, 9 and 16 show how the axes might be configured. The second axis 34 may be different from the first axis 31. In this manner, the first support member 13 may pivot about an axis which is different from the axis about which the second support member 16 may pivot. FIGS. 1A, 5, 8 and 14 show embodiments of the invention in which the first axis 31 is further from a roof 37 of the cart 10 than the second axis 34.

FIG. 8 shows an embodiment in which not all of the support members 13, 16, 19 are on the same side of the roof support 43. Such an embodiment of the invention may have the first end 22 of the first support member 13 at a first location 52 that appears to be between roof supports 43 of the vehicle 10 when a person views the rear of the vehicle 10. The first location 52 need not actually be between the roof supports 43, but in this embodiment would appear to be between roof supports 43. The first end 22 of another of the support members 16, 19 may reside at a second location 53 that appears not to be between the roof supports 43 when a viewer is looking at the rear of the vehicle 10. FIGS. 9–12 show a bracket 58 which may be used to accomplish this embodiment of the invention. FIG. 13 shows such an embodiment of the invention with the canopy in the deployed position. Notice a lower portion of the canopy 49 angles toward the center of the cart 10 as a result of the first support member 13.

The canopy system may include a canopy 49 supported from at least one of the support members 13, 16, 19. The canopy may be supported from the middle portion 28. The canopy 49 may be selectively moved between a deployed position and an undeployed position. When the canopy 49 is in the deployed position, the canopy 49 may provide cover for the storage area 55 of the cart 10. When the canopy 49 is not in a deployed position, the first support member 13 and the second support member 16 may be in a nesting relationship. FIGS. 2 and 5 show the support members 13, 16, 19 in such a nesting relationship.

The canopy system may have a bracket 58. FIGS. 1A, 2, 3 and 4 show one such bracket 58. FIGS. 5–7 show another such bracket 58. FIGS. 8–12 show yet another bracket 58. FIGS. 14–16 show yet another bracket 58. Although FIGS. 1A, 2, 5 and 14 show the brackets 58 mounted on the outside portions of the roof supports 43, it should be noted that the brackets 58 may be mounted on the inside portions of the roof supports 43. The bracket 58 may be supported from the cart 10, for example, the bracket 58 may be attached to a roof support 43 of the cart 10. The bracket 58 may be attached to the cart 10 via a threaded fastening system, such as a nut-and-bolt combination 61, or via an unthreaded fastener system, such as a rivet 64 or via adhesive. In addition, the bracket 58 may be an integral part of the roof support 43, for example by molding the bracket 58 as part of the roof support 43.

The bracket 58 may provide a location used to pivotally attach at least one of the support members 13, 16, 19. In one embodiment of the bracket 58, the bracket provides a different location for each support member 13, 16, 19 to be pivotally attached.

In an embodiment of the bracket 58, the bracket 58 has a first hole 70 and a second hole 73. A first pivot pin 76 may extend through the first hole 70, and extend through the first end 22 of the first support member 13. In this manner, the first member 13 may be pivoted about the first pivot pin 76. A second pivot pin 79 may extend through the second hole 73, and extend through the first end 22 of the second support member 25. In this manner, the second member 25 may be pivoted about the second pivot pin 79. One such bracket is shown in FIGS. 3 and 4. Another such bracket 58 is shown in FIGS. 6 and 7. Yet another bracket 58 is shown in FIGS. 9–12. In FIGS. 3 and 6 the bracket is stepped. In this embodiment, the support members 13, 16, 19 may have different dimensions so that when the canopy 49 is not deployed, the support members 13, 16, 19 nest with each other.

Another bracket is shown in FIGS. 14–16. Such a bracket 58 may be structured so that the first axis 31 and the second axis 34 are located to allow for a nesting relationship in which the middle portions 28 of the support members 13, 16, 19 nest with each other when the canopy 49 is not deployed.

The invention may include a housing 82. FIGS. 17–19 show a housing 82 according to the invention. FIGS. 20–22 show another housing 82. The housing 82 may be made from a semi-rigid material, such as plastic. The housing 82 may be used to enclose all or part of a canopy 49, support members 13, 16, 19, or both when the canopy 49 is not deployed. The housing 82 may have a shape that is similar to that of a support member 13, 16, 19. For example, the housing 82 may have a substantially U-shape.

The housing 82 may be supported from the cart 10, or may be an integral part of the cart 10. FIG. 23A shows a housing 82 which is supported from the roof supports 43 and/or roof 37 of the cart 10. FIG. 231B snows a housing 82 which is supported from the roof supports 43 via housing brackets 83.

FIG. 24A shows a housing 82 that is supported from a support base 84 that may extend from the storage area of the cart 10, or from structures used to hold golf bags. FIG. 24B shows one such support base 84 in more detail. The housing 82 may be provided with holes 86 that may be used along with a hole 87 in the support base 84 to receive a screw or set pin, for purposes of adjusting the height of the housing 82. FIG. 24C shows a different manner of adjusting the height of the housing 82. A support block 89 may be placed in the support base 84, and the housing 82 may be supported from the support base 84. An adhesive, screws or set pins may be used to secure the housing 82, the support block 89, or both to the support base 84.

FIG. 25 shows a housing 82 which is an integral part of the cart roof 37. In this embodiment, the housing 82 may be molded with the cart roof 37, or attached to the cart roof 37 so that the housing 82 appears to be an integral part of the cart roof 37.

In an embodiment of a canopy system according to the invention, the housing 82 may have an opening 85 through which the canopy 49 may extend when the canopy 49 is deployed. FIG. 26 shows how the canopy might extend through the opening 85 when the canopy 49 is in the deployed position. A fastener 88 may be used to attach the canopy 49 to the housing 82. A bar 91 may be provided to distribute forces applied to the canopy 49. The canopy 49 may encircle the bar 91 and may be stitched to itself with stitching 94. In such an embodiment, the fastener 88 may extend through the bar 91.

A housing 82 according to the invention may have an opening 85 through which at least part of at least one of the support members 13, 16, 19 may travel when the canopy 49 is moved from a deployed position to a position in which the canopy 49 is not deployed. In such a housing 82, the support members 13, 16, 19 may be partially or completely covered so as to protect the support members 13, 16, 19, or remove the support members 13, 16, 19 from view. The housing 82 may have an opening 85 that is similar to that of a support member 13, 16, 19. For example, the opening 85 may be substantially U-shaped.

FIG. 27 shows an embodiment of the invention in which a housing 82 is supported from the cart 10 and the bracket 58 is also supported from the cart 10. FIG. 28 shows an embodiment of the invention in which the housing 82 is supported from the cart 10 and the bracket is supported from the housing 82.

It should be understood that an embodiment of the invention in which there is a housing 82 may have merely one support member 13, a canopy 49 supported by the support member 13, and the housing 82 may have the opening 85. As described above, at least a portion of the support member 13 may travel through the opening 85 when the canopy 49 is moved from a deployed position to a stored position. FIGS. 17 and 20 show an embodiment of the invention in which the opening 85 in the housing is positioned so the canopy 49 may extend through the opening 85 when the canopy is deployed. The opening 85 may be substantially U-shaped. More than one support member 13, 16, 19 may be provided. The housing 82 may be made from a semi-rigid material, such as plastic or sheet metal. The housing 82 may be supported from the cart 10, for example, by using a threaded system or an unthreaded system. The housing 82 may also be an integral part of the cart, for example, the roof of the cart 10.

FIGS. 24 and 29 show embodiments of the housing 82 having an extension 97. The extension 97 may be provided to prevent water from running off the roof 37 onto items or people being carried by the cart 10. The extension 97 may be attached to the housing 82, the roof 37, or may be wedged between the housing 82 and the roof 37. The extension may have an edge 103 which resides proximate to a roof 37 of the vehicle 10. FIG. 24A shows an example in which the edge 103 of the extension 97 may be provided proximate to, or in contact with, a rear edge 106 of the roof.

The edge 103 may be in a sealing relationship with the roof 37, and the seal may be provided by a gasket residing between the roof and the extension. FIG. 30 shows a housing 82 having a gasket 109 attached directly to the housing 82. It should be noted that the gasket 109 may be attached to the extension 97, when the extension 97 is provided.

FIGS. 31 through 34 show embodiments in which the extension 97 extends under the roof 37. FIGS. 31 through 34 illustrate that the extension 97 need not contact the roof in order to prevent water from running off the roof 37 onto items or people being carried by the cart 10. Although extension 97 may be placed proximate to the roof 37, lack of contact with the roof 37 may be advantageous in that the extension 97 need not be precisely positioned with respect to the roof 37 in order to provide protection from water running off the roof 37, thereby allowing for easier installation and greater manufacturing tolerances, either of which should reduce cost. Further, by not having the extension 97 in contact with the roof 37, a reduction in noise may be realized.

FIGS. 31 through 34 show an extension 97 in which an end distal from the housing 82 extends upward toward the roof 37 to prevent water from leaving the extension 97 and falling into the storage area 55 or onto the passengers riding in the cart. In this manner, a distal end 98 of the extension 97 is at a higher elevation than an end of the extension 97 which is joined to the housing 82. FIG. 31 shows that one or more substantially planar sections may be used to extend the extension 97 toward the roof 37. FIG. 32 shows an embodiment in which the extension 97 curves toward the roof 37. FIG. 33 shows an embodiment in which the extension 97 has a distal end 98 that is substantially planar. FIG. 34 shows an embodiment of the extension 97 in which the radius of curvature changes. In FIG. 34, the distal end 98 of the extension 97 has a smaller radius of curvature than other portions of the extension 97.

FIGS. 24A, 28 and 31 through 35 show embodiments of the housing 82 in which the housing 82 is attached to the roof 37 of the cart 10 by one or more hooks 112. The hooks 112 may engage a lip on the roof 37 to help attach the housing 82 to the roof 37.

A method according to the invention may result in covering a portion of a vehicle, such as a golf cart. FIG. 36 outlines a method according to the invention. Such a method may provide 200 a first support member which is pivotable about a first axis, and provide 203 a second support member which is pivotable about a second axis. The first axis may be different from the second axis. A canopy may be provided 206 and supported from at least one of the support members. At least one of the support members may be provided so as to pivot the support member about an axis from a first position in which the support member is in a nesting relationship with the other support member, to a deployed position in which the canopy is extended over a portion of the vehicle. The method may include a further step in which a housing is provided 209, wherein the housing has an opening through which at least a portion of the canopy, or at least a portion of a support member, or both, moves when the support member moves from the first position to the second position.

Although the present invention has been described with respect to one or more particular embodiments, it will be understood that other embodiments of the present invention may be made without departing from the spirit and scope of the present invention. Hence, the present invention is deemed limited only by the appended claims and the reasonable interpretation thereof.
