Abstract
A device that folds flat and compact for storage opens to a folding lounge chair with an adjustable angle backrest. The device includes a backrest frame and a seat frame across which is stretched a fabric web to support an occupant. The two frames are joined at one end by an adjustable angle hinge. At a second end of the backrest frame is a handle. At a second end of the seat frame is a pair of wheels on an axle suspended below the seat. Folding U-shape support members can be extended transverse to the frame to hold the chair above a supporting surface. The frames can be opened to lie in a common plane and the chair turned over to form a rolling cart with one or more support members extended to hold items for transporting with the wheels down, the handle up and what had been the under surface of the fabric web now serving as the upper surface to support items.

Description
FIELD OF THE INVENTION
This invention relates to wheeled carts and more particularly to a wheeled cart that converts into a lounge chair and also folds up for easy transport and storage.
Background of the Invention
Chaise lounges with adjustable angle backrests have found widespread application as lawn, poolside and patio furniture. Those having a pair of wheels at the adjustable angle with the backrest as exemplified by U.S. Pat. No. 4,521,054 issued 6/4/85 to Deconinck, have become more popular for their ease of movement from place to place. U.S. Pat. No. 4,323,260 issued 4/6/82 to Suchy teaches a folding beach chair of this type with a short seat in place of the long seat of a typical chaise lounge and an elongate backrest which forms a handle for rolling the device about. A folding support leg that stabilizes the seat when in use as a chair folds out of the way for use of the device as a cart for transporting items. The elongate backrest folds up when the device is folded to a compact shape for storage. U.S. Pat. No. 3,693,993 issued 9/26/72 to Mazarelli et al discloses a beach tote cart with a large removable roller at one end that can serve as a chair or cot. Unfortunately, the roller interferes with chair use unless removed.
Those folding rolling chairs that have wheels at the junction of seat and backrest put the dirty wheels in close proximity to the occupant's clothing when the wheels are large enough to be useful on soft sand.
A chair that puts the wheels out of the way of the occupant and that folds into a convenient small package while also serving as a rolling cart would meet needs not met by the devices of the prior art.
SUMMARY OF THE INVENTION
It is accordingly an object of the invention to provide a folding, adjustable lounge chair that can also function as a wheeled cart in which the wheels do not interfere with the use as a chair. It is another object that the cart be capable of conveniently holding the many items that must often be transported from the vehicle to the beach sand to make a beach outing successful.
The wheeled cart and lounge chair of the invention comprises a rigid seat frame hingedly connected at a first end to a rigid backrest frame by adjustable hinge means that can fix the angle therebetween at a variety of selectable angles including 180.degree.. A flexible fabric or mesh panel stretched across the frames provides a surface to support the reclining occupant. A pair of wheels attached to a second end of the seat frame rotate about a common axis. That axis is disposed in a plane below the plane of the seat so that the wheels do not project excessively into the plane of the seating frame. A plurality of folding supporting leg members are pivotally attached to the frame and arranged to fold into coplanar relationship with the frames for folding storage and to extend perpendicular to the frames for supporting the frames above a support surface when used as a chair.
For use as a cart, the two frames are arranged in a common plane and inverted from the seating position with the wheels on the ground and the combined frames providing a long support for goods with the end of the backrest frame serving as a handle that can be held without stooping. The folding support leg member closest to the wheels is extended to hold the goods at the lowermost point. These and other objects, advantages and features of the invention will become more apparent when the detailed description is read in conjunction with the drawings.
BRIEF DESCRIPTION OF THE DRAWINGS

FIG. 2 is a perspective view of the invention in use as a cart.
FIG. 3 is a side view of the invention in use as a chair in fully reclined position.
FIG. 4 is a top view of the lounge chair of the invention in fully reclined position.
DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
Referring now first to FIGS. 1, 3 and 4, a reclining lounge chair 1 includes a backrest 2 frame with a U shape having a pair of parallel sides 3 joined at one end to a handle end piece 4. The second ends of the sides are joined to the sides 5 of a seat frame 6 by adjustable hinge elements 7 that can be arranged to hold the two frames securely at selected angles between zero and 180 degrees so that the backrest 2 can be in the same plane as the seat 6 as shown in FIGS. 3 and 4 or tilted for sitting upright as shown in FIG. 3 in phantom and in FIG. 1. The sides 5 of the seat frame 6 are bent downward at the ends 9 remote from the hinge 7. An axle 10 is mounted in holes in the ends. A pair of wheels 11 are journalled on the axle 10. Because the axle is below the plane 12 of the seat frame, the wheels do not extend very far above that plane, and they are at the extreme end of the chair where they do not interfere with use of the chair.
A fabric panel 13 is stretched across the frames 26, and the axle 10 to support the weight of the occupant. It is held in place by means well known in the art and may be removable for cleaning. The panel may be mesh, woven webbing or other suitable webs as desired.
Folding support leg members 14, 15, 16 are pivotally connected to the sides of the frame so that they may be folded flat against the frames or extended transverse to the frames for supporting the chair above the support surface such as beach sand, patio and the like. When the frames are adjusted at an angle of 180.degree. so that they are in a common plane and the device turned over, the device now becomes a rolling cart 19 for transporting items to the beach, pool and the like, as shown in FIG. 2. The support leg member 16 is folded down and leg member 14 and optionally leg member 15 are opened out to support items for transport as shown. Strap 20 may be hooked to the frame to hold the items in place during transport. The end 4 of the backrest serves as a handle and the length of the two frames combined puts the handle up high enough for comfortable operation without stooping. The folding leg members are U shaped pieces 21 with cross members 22 for enhanced rigidity.
The above disclosed invention has a number of particular features which should preferably be employed in combination although each is useful separately without departure from the scope of the invention. While I have shown and described the preferred embodiments of my invention, it will be understood that the invention may be embodied otherwise than as herein specifically illustrated or described, and that certain changes in the form and arrangement of parts and the specific manner of practicing the invention may be made within the underlying idea or principles of the invention within the scope of the appended claims.
