ABSTRACT OF THE DISCLOSURE
A utility cart (e.g., for one or more garbage cans or one or more garbage bags) is provided which is made up of preformed tubular elements which are adapted to be detachably assembled together. The cart includes four interrelated elements. The first is an upper generally rectangular framework, the upper framework including a forward, U-shaped portion pro-vided by a forward, transversely extending arm and a pair of rearwardly directed, longitudinally extending, transversely spaced-apart arms, and a rearward, U-shaped portion provided by a rearward, transversely extending arm and a pair of forwardly directed, longitudinally extending, transverse-ly spaced-apart arms, the facing, mutually opposed ends of the rearwardly directed arms and the forwardly directed arms being adjustably telescopi-cally joined together. The second is a lower generally rectangular frame-work, the framework including a forward portion constituted by a pair of identical L-shaped members, each such member including a vertically exten-ding arm adapted to be rigidly secured to the forward transversely exten-ding arm of the upper framework, and a rearwardly directed longitudinally extending arm, the identical L-shaped members being transversely spaced apart, and a rearward U-shaped portion provided by a rearward, transversely extending arm and a pair of forwardly directed longitudinally extending, transversely spaced-apart arms, the facing mutually opposed ends of the rearwardly directed arms and the forwardly directed arms being adjustably telescopically joined together. The third is a vertical handle portion comprising a pair of L-shaped members, each such member including a vertical leg extending below the lower framework to terminate in a synthetic plastic material capped, e.g., vinyl plastic capped, foot and extending above the upper framework to terminate in a rearwardly directed handle extending at right angles to the vertical leg, each such vertical leg being firmly secured at its intersection with the respective rearward transversely extending arm of the upper framework, the L-shaped members being transversely spaced apart.
The fourth is a pair of wheels rotatably mounted on a transversely extending axle removably secured to the rearwardly directed arms of the L-shaped members of the lower rectan-gular framework. In this way, the cart is adjustable in size to accommo-date one or a plurality of garbage cans or one or a plurality of garbage bags, and is provided with legs particularly designed to provide secure static support and control.

Description
This invention relates to a cart. ~ore particularlg~ 1~ relates to a cart especially adapted ~or domestic use for the transportation of household trash, w~ether it be in garbage bags or gar~age cans.
These types of carts are well known in the art. For example, Canadian Patent No. ~84,235 issued June 2~, 1952 to Frank Neal, provides a cart having a relatively low center of gravity whether lt is empty or loaded ar.d which has its load-carrying platform relatively low or close to the roadway. Such cart has large awkward bicycle-type wlleels and a fixed-size skeleton frame with a single central foot thereon. This makes it difficult to transport, in an equally secure fashion, one, two, three or more garbage cans or one, two, three or more garbage bags. In addition, because of the single central foot, the static stability of the cart when at rest is not definitely assured.
- Joyce, in Canadian Patent No. 575,126 issued May 5, 1959, pro-vides such a art which has a wheel-equipped, open frame construction for transporting cans from place to place. The construction, however, provides a rigid cart only when it is braced by structure which enables its sole use to provide circumferential support for two such cans. ~loreover, it is provided with a ground-engaging skid which does not always provide suffi-cient static control. Thus, it cannot be used, interchangeably, for the transportation of one or a plurality of cans or one or a plurality of garbage bags and to be assured that it remains at rest where it is placed.
Marini et al, in United States Patent No. 3,111,333 issued Novem-ber 19, 1963, provide such a cart which was alleged to be light weight, strong and durable and inexpensive to manufacture. They provided such a cart which was so designed and constructed that it could be packaged and sold in knockdown form and could be quickly and easily assembled by a pur-chaser. Apart from the difficulty of assembling such so~called "quickly and easily assembled kits", the cart was limited, because of its particula~
rigidifying bracing structure, to the carrying of only two cans. ~50reover, .,, ~

it was provided with ground-engaging slcids which did not always assure sufficient static control.
Accordingly, it i5 an ob~ect of one aspect of this invention to provide such a cart which is adjustable in si~e to accommodate one or a plurality of garbage cans or one or a plurality of garbage bags.
An object of another aspect of this invention is to provlde such a cart which is provided with legs particularly designed to provlde secure static support and control.
By one broad aspect of thls lnventlon, a utlllty cart i5 provlded which is made up of preformed tubular elements which are adapted to be detachably assembled together, and which comprises: (a~ an upper genera]ly rectangular framework, the upper framework including a for~ard, U-shaped portion provided by a fon~ard, transversely extending arm and a pair of rearwardly directed, longitudinally extending, transversely spaced-apart arms, and a rearward, U-shaped portion provided by a rearward, transverse-ly extending arm and a pair of forwardly directe,d longitudinally exten-ding, transversely spaced-apart arms, the facing, mutually opposed ends of the rearwardly directed arms and the forwardly directed arms being adjus-tably telescopically joined together; (b) a lower generally rectangular framework, the framework including a forward portion constituted by a pair of identical L-shaped members, each such member including a vertically extending arm adapted to be rlgidly secured to the forward transversely extending arm of the upper framework, and a rearwardly directed longltu-dinally extending arm, the~identical L-shaped members being transversely spaced apart, and a rearward U-shaped portion provided by a rearward, transversely extending arm and a pair of forwardly directed longitudinally extending, transversely spaced-apart arms, the facing mutually opposed ends of the rearwardly directed arms and the forwardly directed arms being adjustably telescopically joined together, (c) a vertical handle portion comprising a pair of L-shaped members~ each such member including a verti-

Figure 2 is a perspective view of a cart of a second aspect oE
this invention;
Figure 3 is a perspective view of a cart of a third aspect of this invention; and Figure 4 is a perspective view of a cart of a fourth aspect of this invention.
As seen in Figure 1, the cart 10 comprises an upper rectangular frame 20 and a lower rectangular frame 30, each made up of hollow, light-weight tubular members, e.g., aluminum, polyethylene, etc. Upper, rectan-gular frame 20 is constituted by a pair of fon~ard, L-shaped, identical but mirror-imaged members 21R, 21L, each constituted by a longitudinal arm 22, and a transverse arm 23. The facing mutually opposed ends of arms 23 are non-adjustably telescoped together (as known by a person skilled in the art or otherwise interconnected in a manner kno~n to those skilled in the art) to form the fon~ard edge 24 of the upper rectangular frame 20.
Upper rectangular frame 20 is also constituted by a pair of rear-ward, L-shaped, identical but mirror-imaged members 25R, 25L, each con-stituted by a longitudinal arm 26 and a transverse arm 27. The facing mutually opposed ends of arm 27 are non-adjustably telescoped together (as kno~n by a person skilled in the art or otherwise interconnected in a manner known to those skilled in the art) to form the rean~ard edge 28 of the upper rectangular frame 20~
The facing mutually opposed ends of arms 22 and 26 are adjustably telescopically joined together. The term "adjustably telescopically .. , z~
joined together" means a telescopic connection which is facilitated by having the interior diameter of one of the arms 22 or 26 slightly greater than the exterior diameter of the othar, or Dy naving an extension tnot shown) on one of the arms 22 or 26 whose external diameter is slightly less than the internal diameter of the other arm. The cooperatlng clrcum-ferences may be provlded with longltudinally spaced-apart cooperatlng dlmples in order to provide a plurality of spaced-apart "stops" to provlde for a preselected orientation of the end of one arm with respect to the other arm. Alternatively, a plurality of spaced-apart, alignable aper-tures may be provided whic~, with a cooperating pin, may be used to pro-vide such a preselected orientation of the end of one arm with respect to the other arm. Hereinafter, when the term "adjustably telescopically joined together" is used, it is intended to embrace the two above-described structures, as well as functional equivalents thereof.
The lower rectangular frame 30 is constituted by a pair of L-shaped, but mirror-imaged, members 31R, 31L, each constituted by a lower, longitudinal arm 32 and a vertical leg 33, joined to arm 32 by an integra~
curved portion 34 and terminating at a secure connection 35 (e.g., by welding or bolting) at the upper face of forward edge 24.
20 - The lower rectangular frame 30 is also constituted by a U-shaped member 36 including a transverse rear edge 37 and a pair of spaced-apart transverse arms 38. The facing mutually opposed ends af arms 3B are adjustably telescopically ~oined together to the facing mutually opposed ends of arms 32.
Supporting the rear end of the frame 20 is a pair of legs 41R, 41L, each constituted by a vertical leg 42 firmly connected to the trans-verse rear edge 37 at 43 (e.g., by welding or bolting) and extending upwardly and then forwardly at right angles thereto as handle 45 termina-ting in handle grip 46. The legs 42 extend downwardly as feet 47, termina-ting in synthetic plastic ~aterial capped, e.g., vinyl plastic capped feet 48.

Supporting the forward end of the frame 20 is a pair of wheels 50R, 50L, rotatably mounted in any conventional fashion on transverse axle 51 secured to arms 32 at 52 (e.g., by welding or bolting).
It will be observed that the transverse dimension of the lower frame 30 is less than that of the upper frame 20, in order to provlde greater stability and securement of the garbage cans or gar~age bag~
within the frame~ork. Moreover, the telescopic adjustability provides for secure embracing of one, two or more garbage cans or garbage bags.

The facing mutually opposed ends of arms 22 and 26 are adjustably telescopically joined together. The term "adjustably telescopically .. , z~
joined together" means a telescopic connection which is facilitated by having the interior diameter of one of the arms 22 or 26 slightly greater than the exterior diameter of the othar, or Dy naving an extension tnot shown) on one of the arms 22 or 26 whose external diameter is slightly less than the internal diameter of the other arm. The cooperatlng clrcum-ferences may be provlded with longltudinally spaced-apart cooperatlng dlmples in order to provide a plurality of spaced-apart "stops" to provlde for a preselected orientation of the end of one arm with respect to the other arm. Alternatively, a plurality of spaced-apart, alignable aper-tures may be provided whic~, with a cooperating pin, may be used to pro-vide such a preselected orientation of the end of one arm with respect to the other arm. Hereinafter, when the term "adjustably telescopically joined together" is used, it is intended to embrace the two above-described structures, as well as functional equivalents thereof.
