2. Description of Related Art
Systems that employ computers on golf cars are well known. Exemplary systems are disclosed in U.S. Pat. No. 5,095,430; U.S. Pat. No. 5,364,093; U.S. Pat. No. 5,689,431; U.S. Pat. No. 5,810,680; U.S. Patent Application Publication No. US 2004/0196181 A1; U.S. Patent Application Publication No. US 2005/0228547 A1; and U.S. Patent Application Publication No. US 2008/0108456 A1. While these patents and publications disclose the use of golf car-mounted display devices to facilitate the dissemination of information to golfers and the receipt of information from golfers, none of the patents or publications disclose mounting of a display device so as to allow a golfer to view the device's display screen from any position, regardless of whether the golfer is inside or outside the golf car. For example, none of the aforementioned patents or publications disclose a display device mounting system that would allow a golfer to readily view a prerecorded video of the golfer's swing, which is playing on the display, while the golfer is standing adjacent his or her ball on the fairway preparing to hit the golfer's next shot.
There have been numerous approaches to mounting display devices together with computing devices and/or in vehicles. For example, U.S. Pat. No. 7,133,280 discloses a multi-axial hinge assembly which enables clockwise and counterclockwise rotation of a display device attached to a hybrid notebook/tablet personal computer (PC) relative to a vertical axis. However, the disclosed hinge only allows the display screen to be effectively rotated through a range of 0-180 degrees from its home position facing the PC's keyboard. Thus, the disclosed mounting assembly would not permit viewing of the screen from any location about the PC without also moving the PC. Additionally, while the hinge also permits 180 degree rotation of the display screen about a horizontal axis to permit it to be folded in a clamshell fashion, the mounting assembly does not facilitate substantial changes in height as may be necessary to compensate for variations in the contours of golf courses.
As another example, U.S. Pat. No. 6,412,848 discloses a display monitor system for use in a vehicle. The disclosed display system is mountable to the ceiling of the passenger compartment of the vehicle and allows rotation of the display screen about a horizontal axis in a clamshell fashion from zero to about ninety degrees. The disclosed display system does not facilitate rotation of the display screen about a vertical axis. Thus, the disclosed mounting system is designed to allow viewing of the display screen by users positioned in the rear of the vehicle when the display screen has been rotated into its open position. Since the disclosed display screen cannot be rotated about a vertical axis or have its height modified, it is not readily suited for use by golfers who may want to view the screen from outside the golf car or when not positioned on only one particular side of the screen.
As yet another example of a display mounting system, U.S. Pat. No. 6,874,738 discloses a display mounting system configured to provide for vertical adjustment of a height of a display screen. However, such mounting system limits vertical and horizontal rotation of the display screen to about 90 degrees. Thus, the mounting system is most suitable for mounting a display device, such as a liquid crystal display (LCD) or a plasma display, for a PC or TV set in an indoor environment. Additionally, the limited mobility of the disclosed mounting system would not make the mounting system readily suited for use by golfers who could be positioned at various locations outside a golf car.
As a final example, U.S. Pat. No. 4,220,310 discloses an extensible display mounting assembly that includes a telescoping pole assembly. The telescoping pole assembly is extensible to a desired length and includes, at its extensible end, selectively shaped fixtures for releasably positioning a magnetically adherable mounting member adapted to support a display device. The assembly is suitable for magnetically mounting display materials, such as advertisements, posters, or decorations, at elevated locations above ground level. The assembly is not robust or rigid enough to support a larger or heavier display device, such as an LCD or plasma display screen. Further, the assembly does not provide any mechanism for rotating the display device horizontally or vertically to facilitate viewing at various angles.
In view of the foregoing, a need exists for a golf car and display device mounting system for use therein that overcome the shortcomings of the prior art and facilitate viewing of a display screen mounted to a golf car regardless of whether a user is inside or outside the golf car.

Generally, the present invention encompasses a golf car and a display device mounting system for use therein. In accordance with one embodiment of the present invention, the golf car includes a display device, a golf car housing, and a mounting system for attaching the display device to the golf car housing. The display device displays at least play-related or round-related information to a user or users of the golf car on a display screen of the device. The mounting system attaches the display device to the golf car housing such that the display device is movable when attached to the mounting system so as to facilitate viewing of the display screen by the user(s) whether the user(s) is located inside or outside the golf car housing.
In one embodiment, the mounting system includes a rigid base member, a swivel member mechanically connecting the rigid base member to the display device, and at least one extension member connected to the rigid base member and the golf car housing. The swivel member facilitates rotation of the display device over a range of 0 to about 360 degrees (either full, 360 degree rotation clockwise or counterclockwise, or rotation 180 degrees clockwise and 180 degrees counterclockwise relative to an initial or home position to provide about a 360 degree range of rotation). The extension member(s) facilitates movement of the display device distally relative to one or more points of attachment of the extension member(s) to the golf car housing (e.g., up and down at an angle relative to a surface, such as a dashboard, of the golf car).
By configuring a golf car and its display device mounting system in such a manner, the present invention enables the display screen of the display device to be positioned such that users of the golf car can view the display screen when sitting in the golf car or standing proximate the golf car (e.g., prior to or after hitting a golf ball). To provide such viewing flexibility, the mounting system enables the display device, while remaining secured to the golf car, to be raised and rotated such that a golfer standing outside the golf car can readily view the display screen. The mounting system also enables the display device to be lowered so as to not obscure the view of a user driving the golf car when the golf car is in motion.
The present invention can be more readily understood with reference to
According to the embodiment of
In a further embodiment, the swivel member 104 may be multi-axial, thereby facilitating both horizontal rotation as discussed above, as well as vertical rotation of the display device 102 about a horizontal axis 115 that is substantially perpendicular to the vertical axis 113. In one embodiment, the swivel member 104 facilitates rotation of the display device 102 about the horizontal axis 115 in the range of 0 to about 90 degrees in a direction opposite the display screen 103, where the zero degree reference corresponds to the display device 102 being fully upright. In an alternative embodiment, the swivel member 104 facilitates approximately 180 degree rotation of the display device 102 about the horizontal axis 115. The swivel member 104 may be implemented using a multi-axial hinge, such as the hinge disclosed in U.S. Pat. No. 7,133,280 B2, which is incorporated herein by this reference, modified to permit approximately 180 degree rotation about the vertical axis 113 in both the clockwise and counterclockwise directions relative to a home position. The swivel member 104 may be alternatively implemented using a ball and socket mechanism, a pivoting set of arms, or a set of parallel or scissors-style linkages.
The rigid base member 106 supports the swivel member 104 and may be fabricated as a metal or plastic (e.g., polyvinylchloride (PVC)) bar or tube sufficient in length to allow attachment of the base member 106 to the pair of parallel extension members 108, 109. The base member 106 may be extruded or constructed using any other known fabrication method. In one embodiment, the base member 106 is a hollow structure fabricated from approximately ⅛″ inch (approximately 3.2 millimeter) thick metal or plastic that defines a cavity in which the swivel member 104 is positioned and connected to the base member 106. In an exemplary embodiment, the base member is approximately 10 inches (approximately 25.4 centimeters) long by approximately 2 inches (approximately 5.1 centimeters) wide. The base member 106 may optionally include or be connected to a handle 105 to assist a user of a golf car containing the mounting system 100 in raising and lowering the display device 102.
The extension members 108, 109 are oriented generally parallel to one another and are connected in a conventional manner to the base member 106 to facilitate movement of the display device 102 distally from points of attachment of the extension members 108, 109 to the golf car housing. An exemplary golf car containing the mounting system of
In one embodiment, each of the extension members 108, 109 is a telescoping extension member that includes an outer tube 110 and an inner tube 111. Alternatively, the extension members 108, 109 may be implemented using any other mechanical, electric, pneumatic, or hydraulic means, such as, but not limited to, pivoting or sliding rails or arms, accordion or scissors-style arms, drawer slide, four or more bar linkages, magnetic levitation, cables or belts, drive screws, pneumatic cylinder ball detent, electronic solenoid, and mechanical clamps.
When the extension members 108, 109 are implemented as telescoping members, the inner tube 111 moves in and out of a chamber defined by the outer tube 110 responsive to a force exerted on the inner tube 111. The force may be manual, such as when a user pulls up or pushes down on the handle 105, the display device 102, or the base member 106. When the mounting system 100 is designed for use of manual force to raise and lower the display device 102, the mounting system 100 may include conventional cam lock mechanisms or constricting brakes or clamps to enable the inner tubes 111 to be locked or clamped at desired height positions.
Alternatively, the inner tube adjusting force may be electromechanically generated by a motor (not shown), such as a conventional hydraulic motor, located in or on the golf car. In such a case, the base member 106 may optionally include or support a switch 107 that activates and/or controls the motor to enable a user to select when to raise and lower the display device 102. In one embodiment, the inner tube 111 includes a cavity through which wires and cabling may be run between the display device 102 and its source controller (not shown), which may be installed in the dashboard or other location of the golf car, as well as between the switch 107 and the motor (when used).
To improve the overall strength of the mounting system 100, especially when designed to permit manual force to be used to raise and lower the display device 102, the mounting system 100 may optionally include one or more rigid support members 116, 117, 119. The support members 116, 117, 119, when used, are attached in a perpendicular manner to the pair of extension members 108, 109 to maintain the parallel arrangement of the extension members 108, 109 in the presence of the manual or other forces exerted on the mounting system 100. When the extension members 108, 109 are telescoping members as shown in
The optional support members 116, 117, 119 are positioned between the base member 106 and the primary point or points of attachment of the mounting system 100 to the golf car housing or chassis. The point or points of attachment of the mounting system 100 to the golf car housing may be provided by appropriate hardware connecting some or all of the support members 116, 117, 119 to the golf car chassis. As detailed above, the mounting system 100 allows the display device 102 to be movable such that a user can view the display screen 103 regardless of whether the user is located inside or outside the golf car and whether the user is positioned at virtually any angle relative to the inside compartment of the golf car.
The mounting system 100 may be attached to the golf car housing 401 under the dashboard 407 by mounting the support members 106, 107 to the housing 401 using known fasteners, such as screws or bolts. The dashboard 407 may be modified to accept the mounting system 100 by, for example, including apertures through which the extension members 108, 109, or portions thereof, may pass to permit connection to the rigid base member 106 or by including semi-circular or arched recesses or grooves in an underside and/or front surface of the dashboard 407 to permit passage of the extension members 108, 109. Alternatively, the mounting system 100 may be connected to the golf car housing 401 such that no modification to the dashboard 407 is necessary (e.g., by attaching the mounting system 100 to a floor or wall of the golf car housing 401 such that the extension members 108, 109 may pass between the dashboard 407 and the seat 404). In the event that the mounting system 100 includes a motor (not shown) to facilitate automatic raising, lowering, and/or rotation of the display device 102, the dashboard 407 or some other portion of the golf car 300 may be equipped with a switch 409 for use in controlling the operation of the motor.
When installed in the golf car 400, the mounting system 100 allows the display device 102 to be moved such that the display screen 103 may be viewed by a user whether the user is located inside or outside the golf car 400. For example, when the extension members 108, 109 are telescoping members and the display device 102 has been raised such that the inner tubes 111 of the extension members 108, 109 are fully or substantially extended as depicted in exemplary form in
Referring back to
The present invention encompasses a golf car and a display device mounting system for use therein. With this invention, a display screen of a display device mounted in the golf car can be viewed by a golfer whether he or she is sitting in the golf car or standing proximate the golf car (e.g., prior to or after hitting a golf ball). The mounting system of the present invention provides enhanced viewing flexibility of an attached display device by enabling the attached display device, while remaining secured in a golf car, to be raised and rotated such that a golfer or other user standing outside the golf car can readily view the display screen of the display device. The mounting system also enables the display device to be lowered so as to not obscure the view or movement of a user driving the golf car when the golf car is in motion.
