Abstract: A drive unit for a golf cart having a motor and a pinion mounted on a drive shaft extending from the motor. The motor is pivotally mounted on a leg of the cart and is adjustable to a number of positions including one where the pinion engages a wheel on the cart to drive the cart and another where the motor does not interfere with folding of the cart. A battery is suspended from the cart to power the motor, and a thumb switch is included to selectively activate the motor. Biasing structure is included to improve engagement of the pinion against the wheel when the motor is in its driving position.

Abstract: A golf bag having an elongated container with a retractable rolling assembly coupled to the container. The rolling assembly can be moved between an extended position and a retracted folded position. A locking device securely retains the entire rolling assembly in its folded position. A locking arrangement locks the entire rolling assembly in its extended position. A detachable wheel is connected at each end of the shaft of the rolling assembly by a floating ring positioned about a reduced diameter portion of the shaft. The ring is normally maintained by gravity in an interference position wherein it extends beneath the periphery of the shaft to prevent removal of the wheel. The ring can be manually aligned with the shaft to permit the wheel to be mounted on and removed from the shaft.

Abstract: An undercarriage comprising a rectangular, tubular frame defining a plane, two supporting members having upper U-shaped sections and angled lower sections, a pair of axles, a pair of wheels, and a pair of locking devices. Each upper U-shaped section is pivotally attached to one of the end members of the frame with the base portion of the U-shaped section extending above the plane when the supporting members are in an unfolded position. Each lower section is fixed to an end of one of the legs of the upper section and extends below the plane. Each axle is attached to a lower end of one of the angled lower sections. Each wheel is rotatably mounted on one of the axles. Each locking device is interconnected between one of the end members of the frame and one of the supporting members to lock that supporting member in the unfolded position. The supporting members are entirely within the plane defined by the frame when in a folded position.

Abstract: A two-wheeled golf cart provided with a container intended for receiving the wheel undercarriage, the legs of which can be moved apart to operative position, and on which the container is arranged in weightless outbalanced condition, whereby the wheel undercarriage can be readily folded out of the container and retracted into it respectively by means of a simple handgrip only, and thereby being ready for immediate use. This task is solved thereby that the pull rod is designed as a two-armed lever, the shorter arm of which is adapted to act upon a first linkage system for causing the wheel undercarriage to be retracted into and folded out of the container respectively, a second linkage system being provided to be acted upon by the pull rod in order to act upon the wheel undercarriage, when this is in its folded-out position, for effecting that its legs, each of which carries a wheel, are moved apart and pulled together respectively.

Abstract: A rollable golf bag having an elongated golf bag container with a collapsible rolling assembly coupled to the container. The collapsible rolling assembly is movable between an extended position to permit rolling of the container, and a folded position to facilitate carrying of the container. Wheels connected on the rolling assembly are detachable and can be stored within a storage compartment of the container.

Abstract: A piece of luggage has a case with a substantially flat bottom wall formed with a pair of generally parallel grooves, with a pair of longitudinally spaced relatively wide outwardly open recesses in each groove, and with a wheel cutout adjacent a lower end of each groove. Respective solid support blocks are force-fitted in the recesses and are each formed with a throughgoing passage aligned with the respective groove. Respective tubes extend longitudinally along the grooves through the respective passages in the blocks and are rotatable in these blocks. Pivot mounts for wheels are carried on the lower tube ends and a handle is connected to the upper tube ends and are displaceable longitudinally relative thereto. Structure in the tube between the handle and the pivot mounts pivots these mounts through about 90.degree. between positions with the wheels in the cutouts and the wheels standing up from the bottom wall on displacement of the handle longitudinally away from the upper tube ends.

Abstract: A golf bag cart providing wheeled support for a golf bag and that is collapsible to a relatively flat storage condition. The cart includes an elongated frame member having a pair of wheel supporting legs pivoted thereto. A bracket member joins the legs to the frame member to enable folding of the legs from spread, operative positions wherein the legs project outward of the frame, and compact storage positions wherein the legs are folded close to the frame with the wheels thereon situated adjacent a handle end of the frame. A removable tensioner releasably secures the legs in the operative and inoperative storage positions.

Abstract: A collapsible luggage carrier being pulled along behind the user rolling on two wheels. So as to possess outstanding portability along with universal usefulness as a transport device the carrier is provided with a spacious base platform frame comprising two X-shaped frames laterally arranged and pivotally connected together, a back frame comprising a telescopic handle bar and a pair of links connected thereto and being pivotally connected to the base platform frame at three equidistant portions in lateral alignment, expanding members, for holding both the frames in their laterally expanded state, and none of rigid side assemblies disposed to opposite sides of the carrier. The both frames are unfoldable at a right angle with each other and each foldable over the other. The frames are laterally expansible and collapsible with each other. The carrier is collapsible into the form of a compact, short and slender bundle without disassembly.

Abstract: First and second legs (4 and 5) of a collapsible tripod (1) are pivoted to a third leg (6) and interconnected by two interpivoted bracing links (15 and 16).To swing the first and second legs (4 and 5) towards and away from the third leg (6), first and second tie members (24 and 25) extend, respectively, from the first and second legs (4 and 5) to an actuating member (18) which is movable longitudinally of the third leg (6).To prevent relative movement between the legs (4, 5 and 6), when the tripod (1) is in its extended condition, a control link (32) extends from the pivotal interconnection between the two bracing links (15 and 16) and the actuating member (18) and locking means (21) are provided for releasably locking the actuating means (18) to the third leg (6).

Abstract: An improved foldable golf cart seat assembly is disclosed which includes a horizontally disposed seat frame that is attached to the main golf bag carrying frame assembly and that encircles the golf bag. A seat member is pivotably attached to the seat frame and has a foldable leg assembly that is attached to its undersurface and that may be arranged so as to support the seat member in a generally horizontal position when the seat member is in use. When not in use, the seat member may be moved to a generally vertical position and the leg assembly may be folded so that it is out of the way and adjacent to the undersurface of the seat member.

Abstract: A two-wheeled golf bag cart has a support for a battery powered electric motor and it includes a gear box to the input shaft of which the motor is connected and which has axially aligned oppositely disposed output shafts. The wheels of the holder have hubs through which stub shafts extend. An intermediate shaft for each wheel has universal joints, one connecting it to the stub shaft and the other to the appropriate output shaft. The support includes an upright having a handle and a golf bag holder is connected to the support and the upright. Two links are connected to each hub with one link connected to the support and the other a slide slidable lengthwise of the upright. The slide has a lock connecting it to the upright when the linkage is positioned to space the wheels apart but releasable to enable the slide to be moved towards the handle to collapse the cart for storage with the linkage folding to bring the wheels close together and towards the handle.
