WHEELED CARRIERS, ESPECIALLY GOLF-BAG CARRIERS Filed Sept 29, 1959 3 Sheets-Sheet 5 [n ven [or /AA/ 0000/9411 Mam/0W A ltorneys United States Patent M This invention relates to wheeled carriers, especially golf-bag carriers, in which a pair of wheeled leg structures are pivotally mounted on a load receiving frame for movement between extended and collapsed positions.

An object of the invention is to provide simple and eflicient actuating means for effecting said movement of the leg structures. A

A further object of the invention is to provide for resilient support of the load on the wheeled leg structures.

According to the invention I provide a wheeled carrier, especially a golf-bag carrier, comprising a load-receiving frame, a pair of wheeled leg structures pivotally mounted on the frame for movement from a collapsed position adjacent to the frame outwards from the frame and laterally apart from each other to an extended position, lever means on the frame, and resiliently deformable strut means extending between and pivotally connected to the lever means on the one hand and said leg structures on the other hand, said strut means on actuation of the lever means causing movement of said leg structures which is simultaneously outward and lateral and said strut means being resiliently deformed laterally by such movement.

An embodiment of the invention will now be described, but merely by way of example, with reference to the accompanying drawings in which:

FIG. 1 is a perspective view of a carrier in bag-supporting position.

FIG. 2 is a side View of the upper end of the carrier, with the lever means in collapsed position.

FIG. 3 is a top plan View of FIG. 2.

FIG. 4 is a perspective view of the carrier of FIG. 1 with the leg means in collapsed position.

FIGS. 5 and 6 are perspective views cor-responding to FIGS. 1 and 4 and showing a modified form of wheelcarrying legs.

Referring to the drawings:

A golf-bag carrier consists of a main frame in the form of a straight tube 1, a bag-supporting V-frame 2 projecting from the bottom of the tube, a bag-receiving rest 3 at the top of the tube, a bag-receiving rest 3A at the bottom of the tube and fitted with a bag-securing strap 3B, and a pair of wheel-carrying leg structures 4 and 5 pivotally mounted in a pair of outwardly divergent brackets 6 and 7 on the tube 1 intermediate the tube ends for movement between a collapsed position closely alongside the tube 1 (FIG. 4) and an expanded position in which they diverge in a plane at an angle to the tube 1 (FIG. 1). The leg structures consist of pairs of parallel tubes 8 and 9 pivotally connected at 8A and 9A to the brackets 6 and 7 and at 8B and 9B to brackets 10 and 11 carrying stub axles (not shown) on which the wheels 12 and 13 are removably mounted. Thus, the wheels 12 and 13 in collapsed position (FIG. 4) lie one on each side of the frame tube 1 in parallel vertical planes and permit wheeling of the carrier.

A pair of spaced bracket plates 14 are formed by a U-plate projecting laterally from the top of the frame tube 1, and accommodate between them the lower end of a handle tube 15 which is hinged at said end on a pivot 16 bridging the plates and has a hand grip 17 at its upper end. A pair of segmental lever plates 18 on said 3,043,602 Patented J uly- 10, 1 962 pivot 16 slidably engage the outer faces of the bracket plates 14 and are penetrated by a diametral clamping bolt 19 on the handle tube 15, the bolt 19 also entering open-ended arcuate slots 29 in the bracket plates 14 and having thereon a wing nut 21 for use in clamping the lever plates 18 and handle tube 15 to the bracket plates.

The lever plates 18 have pivotally connected thereto strut means consisting of a spring-steel round-section wire 22 of substantially inverted U-shape, the base of the U penetrating aligned bearings 23 in the lever plates and being disposed to enter the arcuate slots 20 in the bracket plates 14. The free ends of the wire 22 are inwardly turned to form pivot pins 24 which lie in bearing apertures in a pair of opposite leg- structure tubes 8 and 9, intermediate the tube ends, the pins 24 being turnable relatively to bearing sleeves secured within the apertures.

The bag-receiving rest 3 at the top of the frame tube 1 consists of a leather strap 25 secured at its ends to the g V outer ends of opposed U-frames 26 and 27 of springsteel wire which frames are clamped at their inner ends to the tube 1 by a bolt 28 extending through the tube, and are supported in position by a flanged guide plate 29 secured to the tube 1 and apertured to receive the ends of the U-frames. The cantilever U-frames 26, 27 yield resiliently under pressure so that the rest forms a spring sling which accommodates itself to the contour of the bag resting thereon. A buckled strap 30 threaded through end slots in the strap 27 secures the bag of clubs to the strap 25.

With the wheeled leg structures 8 and 9 in collapsed position (FIG. 4), the handle tube 15 lies alongside the frame tube 1 with the lever plates 18 clear of the bracket plates 14, and the U-wire 22 unstressed.

To expand the wheeled leg structures 8 and 9, the handle tube 15 is raised until the U-wire 22 and clamping bolt 19 engage in the arcuate slots 20, whereupon the wing nut 21 is tightened to clamp the lever plates 18 and the handle tube 15 to the bracket plates 14. The limbs of the U-wire 22 act as connecting rods to raise the leg structures 8, 9 to expanded position and are resiliently deflected laterally from each other during the expanding movement. With the leg structures fully expanded (FIG. 1), the U-wire 22 is located at the inner ends of s lots 20, just past the dead centre position in relation to the handle pivot 16 and pivot pins 24, and the'limbs of the U-wire serve as struts to maintain the wheel structures 8, 9 against upward collapse under load. Moreover, angular adjustment of the handle tube 15 between plates 14, to a position giving optimum balance in use of the carrier, is permitted without materially affecting the position of the leg structures 8, 9.

The U-wire 22 constitutes a spring mounting for the wheeled leg structures 8 and 9 in use of the carrier.

To collapse the leg structures 8, 9, the wingnut 21 is loosened and the handle tube 15 is pivoted downwards. The limbs of the U-wire 22 act as connecting rods to lower the leg structures to collapsed position, and during the lowering movement are urged inwards towards each other to their initial undeformed position.

In the modification shown in FIGS. 5 and 6, the wheelcarrying leg structures 4A and 5A consist of single tubes with cranked ends 4B and 5B pivoted in a pair of downwardly and outwardly divergent sockets 6 and 7 on the tube intermediate the ends of the tube, for gyratory movement between collapsed and expanded positions. In this modification the wheels 12 and 13 are removably mounted on stub axles carried by the tubes 4A and 5A, and are only parallel to each other in the expanded position, in the closed position being inclined towards each other and to the frame 1. Also the limbs of the U-wire 22 are not only deflected laterally during/the expanding movement but also undergo slight torsional displacement as their pivotal axes on the tubes 4A and 5A are out of parallel with the pivotal axes of the tubes themselves. Also, the rest 3 is secured to the base of the U-plate forming the bracket plates 14, the top of the tube 1 terminating within the U-plate.

By virtue of the invention, the actuating mechanism for expanding and collapsing the wheeled leg structures ismuch simplified, there being no need for elaborate joints, and the cost of manufacture is therefore consider ably reduced.
