Abstract
Description
- The present invention relates to a motorized golf bag cart, and, more particularly, to such a motorized cart which is stable and efficient when loaded with a golf bag, but which collapses to an extremely compact size when not in use.
- A number of motorized golf bag carts have been developed to carry a golfer's bag while he or she walks a golf course. These carts have taken a number of different configurations, but have generally fallen into two broad categories, namely motor and battery attachments for existing golf bag hand carts, and self contained, complete, motorized carts. Somewhat representative of the first type is that shown in U.S. Pat. No. 3,941,198 to Chris Kappas, and entitled DETACHABLE POWER UNIT FOR A GOLF BAG CART. In the Kappas patent, an articulated frame includes a battery storage area and a separate motor compartment holding a motor which is positioned immediately above a single drive wheel. The entire frame is removably attachable to a standard two-wheeled golf bag hand cart to convert it to a motorized operation. The drive wheel is chain driven and has no steering capability. Other, similar designs are found in U.S. Pat. No. 4,019,597 to Carmichael, U.S. Pat. No. 4,418,776 to Richard Weirick and U.S. Pat. No. 5,232,065 to James Cotton. Numerous examples of selfcontained, motorized golf bag carts also exist. For example, U.S. Pat. No. 4,063,612 to Morris Weiss is a four wheel design with a motor driving the front pair of wheels which are steered by an articulating handle. U.S. Pat. No. 3,952,821 to Charles Craven is a simple two wheel motorized design in which a motor drives a single axle positioned between the two wheels. U.S. Pat. No. 4,106,583 to Edwin Nemeth is a three motorized cart in which a battery compartment is attached to a central, elongate frame and a pair of independent motors are attached to respective front drive wheels. Other examples include U.S. Pat. No. 4,356,875 to Robert Clune, U.S. Pat. No. 4,538,696 to Lee Carter, U.S. Pat. No. 4,974,693 to Masao Nakai et al., U.S. Pat. No. 5,137,103 to James Cartmell, and U.S. Pat. Nos. 5,167,389, 5,180,023 and 5,749,424 to Eric Reimers.
- The prior art motorized golf bag carts, as represented by the above patents, seem to suffer from one of two problems. If they are stable, four wheeled designs, they do not collapse enough to be easily stored and transported. Conversely, the three wheeled designs, although they can generally be collapsed to a smaller storage configuration, are much less stable on sloping or uneven terrain.
- It is clear, then, that a need exists for a motorized golf bag cart which incorporates a stable, four wheel design with a relatively wide wheel base, and yet is easily collapsible to a size which allows for efficient storage and transport.
- The present invention is directed to a motorized golf bag cart with a stable, four wheel design. The inventive cart includes a base frame with a battery storage area positioned immediately ahead of a motor compartment which includes a variable speed drive motor. The battery storage area is formed by a telescoping tube assembly such that the base frame can be extended to accommodate a storage battery, or retracted to eliminate the battery storage area during storage and transport. The drive motor is linked to a rear, drive axle via a direct gearing transmission to eliminate problems with drive belts or chains. The drive axle drives a pair of drive wheels positioned on respective opposite sides of the base frame. The drive wheels can be made free wheeling in the event of a dead battery, a failed motor or other drive failure. Positioned on the base frame immediately ahead of the battery storage area are a first and a second transversely extending tube which are hollow and which are sized to receive respective first and second telescoping support axles. Each axle extends outward from its respective tube and mounts one of a pair of front support wheels. Each axle has a pair of locking pin receptacles spaced and sized to receive a respective one of a pair of spring loaded locking pins which extend through an opening in each tube. The axles thus telescope inward and outward relative to the tubes between an extended, operative position and a retracted, storage position. A bag receptacle is attached to and extends forward from the pair of hollow tubes. An articulating handle is attached to the rear of the base frame, with the handle being hinged in two places to allow it to be folded flush against the base frame when stored. A combination speed control rheostat and switch is mounted on the handle near a grip thereof for convenient motor control. In an alternative embodiment, the first and second, tandem hollow tubes are replaced by a single hollow tube which telescopically accommodates both support axles.
- The principal objects of the present invention include: providing an improved motorized golf bag cart; providing such a cart which is extremely stable in operation, yet is collapsible to a small configuration for storage and transport; providing such a cart in which the support wheels are telescopically received in the base frame such that they can be moved from an operative, wide wheel base position to a narrow storage position; providing such a cart in which a base frame includes a battery storage area which can be selectively collapsed for storage once the battery is removed; providing such a cart which includes an articulating handle which folds to a compact configuration for storage; and providing such a cart which is particularly well adapted for its intended purpose.
- Other objects and advantages of this invention will become apparent from the following description taken in conjunction with the accompanying drawings wherein are set forth, by way of illustration and example, certain embodiments of this invention.
- The drawings constitute a part of this specification and include exemplary embodiments of the present invention and illustrate various objects and features thereof.

- As required, detailed embodiments of the present invention are disclosed herein; however, it is to be understood that the disclosed embodiments are merely exemplary of the invention, which may be embodied in various forms. Therefore, specific structural and functional details disclosed herein are not to be interpreted as limiting, but merely as a basis for the claims and as a representative basis for teaching one skilled in the art to variously employ the present invention in virtually any appropriately detailed structure.
- Referring to the drawing FIGS.1-7, a motorized golf bag cart in accordance with the present invention is illustrated and generally designated as 1. The
cart 1 includes a tubular base frame 2. The base frame 2 is formed by afirst tube 3 received within a second tube 4 whose inner diameter is slightly larger than the outer diameter of thefirst tube 3. - Referring to FIGS.3-5, and 7, a locking pin receptacle 5 is attached to the exterior of the second tube 4 and a locking pin 11 is positioned within the receptacle 5 and engages a
coil spring 12 therein. Thespring 12 tends to force the pin 11 inward through an pin aperture 13 (FIG. 7) in the second tube 4 and into the interior thereof. Thefirst tube 3 includes a pair of lockingpin apertures 14 and 15 positioned to receive the locking pin 11 therein. An upper portion of the locking pin 11 includes a throughbore 21 extending transversely there through and a locking pin keeper 22 is positioned within the throughbore 21, which keeper 22 prevents the pin 11 from being drawn into the receptacle 5 and also provides a gripping surface to allow a user to retract the pin 11 against the force of thespring 12. - The
first tube 3 can thus be telescopically extended and retracted relative to the second tube 4 between an extended, operative position, as shown in FIGS. 1, 3 and 4, at which thepin aperture 14 receives the pin 11 and a retracted position at which the pin aperture 15 receives the pin 11. This area of the base frame 2 forms abattery storage area 23 to accommodate astorage battery case 24 and battery (not shown) for providing power to a drive motor 25. A pair ofangle members housing 28 to support respective sides of thebattery storage case 24. Thetelescoping tubes 3 and 4 allow the base frame 2 to be collapsed longitudinally once the storage battery andcase 24 are removed, as illustrated in FIGS. 2 and 5. - Referring to FIG. 3, the
first tube 3 of the base frame 2 is attached to and extends rearward from thehousing 28. Thehousing 28 contains a pair of transversely extendinghollow tubes telescoping support axles support axle respective tube front support wheels 35. The support axles 33 and 34 and thetubes support axle 33 and thetube 31 will be further described. Thesupport axle 33 includes a pair of lockingpin apertures aperture pin 43 positioned within a lockingpin receptacle 44 attached to the exterior of thetube 31 and engaging acoil spring 45 therein. The lockingpin receptacle 44,pin 43 andspring 45 are identical in form and function to the locking pin receptacle 5, pin 11 andcoil spring 12, and, thus, will not be further described herein. - The
support axle 33 can thus be telescopically extended and retracted relative to thetube 31 between an extended support position at which thepin aperture 41 receives thepin 43 and a retracted, storage position at which thepin aperture 42 receives thepin 43. Thetelescoping support axles support wheels 35 to be collapsed transversely inwardly to an extremely compact configuration, as illustrated in FIG. 2. - The base frame2 includes a
motor support area 61 and a variablespeed drive motor 62 is attached thereto. Thedrive motor 62 drives adrive axle 63 via a direct gearing transmission 64 in a known manner. Themotor 62 and transmission 64 are housed within amotor enclosure 65. A pair ofdrive wheels 71 are driven by thedrive axle 63 to power thecart 1. It is contemplated that a disengagement feature (not shown) can be provided to disengage thedrive wheels 71 from theaxle 63 in the event of a power failure, such that thedrive wheels 71 can become free wheeling. - The
cart 1 includes abag receptacle 91 attached to and extends forward from the housing 38, with the receptacle shaped to receive abase portion 92 of agolf bag 93, shown in phantom lines in FIG. 1. - Referring to FIGS. 1, 4 and5, an
upright post 94 is attached to and extends upward at an approximate 90 degree angle from the second tube 4 of the base frame 2. Apivot support 95 is attached to thepost 94 near the upper end and afirst handle member 96 is pivotably attached to theupright post 94 thereby. Thefirst handle member 96 is preferably of a two-part telescoping construction with an inner tube 97 telescoping into an outer tube 98, which allows it to be collapsed downward for storage to render it more compact. Thefirst handle member 96 can be locked into the extended position via a spring pin 99. - A golf
bag securing loop 101 is attached to thefirst handle member 96 such that it is pivotable with thefirst handle member 96 with respect to thepost 94. Asecond pivot support 102 is attached to thefirst handle member 96 near the top thereof. An articulating second handle member 103 is attached to thesecond pivot support 102, with the second handle member 103 being locked into an operative position by alocking pin 104 and unlocked to be folded to the compact storage position shown in FIG. 2 by releasing thelocking pin 104. - A motor on-
off switch 106 and a motorspeed control rheostat 107 are attached to a generally semi-circularhandle control plate 108 to allow a user to easily control motor operation and speed. - FIG. 6 illustrates an alternative embodiment for telescoping the
support wheels 35 a of a modified bag cart 1 a. In this alternative embodiment 1 a, the first and second, tandemhollow tubes drive axles support axle pin apertures 41 a and 42 a spaced apart thereon with eachaperture 41 a and 42 a sized to selectively receive a spring loaded lockingpin 43 a positioned within a locking pin receptacle 44 a. Again, the locking pin receptacles 44 a and spring loadedpins 43 a are identical in form and function to the locking pin receptacle 5, pin 11 andcoil spring 12, and, thus, will not be further described herein. - Each
support axle pin 43 a and a retracted, storage position at which thepin aperture 42 a receives thepin 43 a. The second embodiment of bag cart 1 a in FIG. 6 can include a telescoping battery storage area similar to thebattery storage area 23, or this feature can be eliminated for cost saving purposes. - The invention has been illustrated and described in a particular design, but other mechanisms for telescoping the
support wheels 35 andbattery storage area 23 can be visualized which might be equally effective. For example, the base frame 2 can be made of two or more telescoping support tubes instead of thesingle tubes 3 and 4. The size and shape of the various frame and support axle tubes is illustrative only, and other shapes and sizes could perform as well. Other variation will occur to those skilled in the art. It is thus to be understood that while certain forms of the present invention have been illustrated and described herein, it is not to be limited to the specific forms or arrangement of parts described and shown.
