This invention relates to an ingenious self-service store-type vehicle, which may be unitarily visualized as a combination foldable basket and carriage, the carriage having the additional funcli tion of a carrier for the ordinary hand-type market basket.

In reducing to practice the principles of the broad inventive concept, I have had in mind the provision, for self-service store use, a collapsible or foldable, roller-equipped carrier for an ordinary market basket, a structure of this type being aptly fitted for the purposes intended in that when not in use it may be folded into compact form for convenient placement in an out-of-the way location in the store.

As a more specific exemplification of the preferred embodiment of the invention, it has been found expedient and practicable to not only provide a collapsible carriage usable as a carrier for 90 an ordinary market basket, but to also build into the carriage a readily available and foldable receptacle which may be employed as the principal basket to facilitate shopping by self-serving customers.

35 Other features and advantages of the invention will become more readily apparent from the following description and the accompanying illustrative drawings.

In the drawings, whereinlike numerals are employed to designate like partsthroughout the views:

Figure 1 is a side elevational view showing one embodiment of the invention constructed in accordance with the principles of the conception and showing how the structure is set up for use by the customer.

Figure 2 is a view which maybe conveniently described ,as a rear elevational view, that is, a

view of Figure 1, observing it'in a direction from left to right.

Figure 3 is a side elevation based on Figure 1 and showing the relationship of features when the complete structure is collapsed into its folded form to occupy an out-of-the-way position when not in use.

Figures 4 and 5 are horizontal sections on the lines 4-4 and 5-5, respectively, of Figure 1.

Figure 6 is a side elevational view showing a modification of the invention and illustrating the parts in the process of folding into collapsed state.

Referring now to the drawings by distinguishing reference numerals, it will be observed that the portable wheel-supported carrier or carriage 66 is made up primarily of two complemental leg units 1 and 8, having the function of basket expanding and contracting levers. The main unit I is here shown as of general U-shaped form and the upper portion thereof functions as a convenient handle as at 9. On the lower ends of the 5 arm portions thereof I provide suitable wheels l0. As seen in Figure 2, the numeral ll constitutes a cross-brace, while the numerals l2 indicate adapter brackets to accommodate the rollers or wheels l8. Then, as shownin Figure 1.0 1, the numerals l3 designate stay members in the nature vof metal straps or arms, these being pivotally attached at one end as at l4 to the lower portions of the arms of the leg frame I. The units I and 8 are disposed in intersecting 15 relationship and pivotally joined together as at i5 intermediate their ends. It will be observed that the legs 8 are somewhat shorter than the legs embodied in the frame I. On the lower ends of the legs 8 I provide any suitable type swivelly 2 mounted casters i6. Associated with the casters are extension brackets l1 suitably designed to rest on the floor when the structure is folded, as seen in Figure 3, to lift the rollers and casters up out of contact with the floor and to allow the 35 device to be rested against a wall or the like without falling. Returning to the stay arms l3, it will be seen that these are collapsible with the frames 1 and 8 and at their rear ends they project between the legs 8 and have stop elements l8 to engage said legs and to prevent the spread of the lower diverging portions of said parts I and 8. This is brought out in Figure 1 of the drawings. It might also be conveniently mentioned here that the, numeral l9 designates a basket rack 35 which may be of any suitable type, and this is built on and supported by the same stay members 8. At its front the rack is provided with appropriate guards 20 to facilitate maintaining the ordinary market basket (not shown) on the rack 40 when desired. The frame member of the rack I9 is of general U-shaped form, and its front portion 2| projects beyond the guards 28. The rear end portions are inclined in relation to the arms i8, as indicated at 22. 7

Looking nowat Figure 2, attention comes to the numerals 23 and 24, which designate companion yokes mounted between the legs 8. The inclined members 22 rest on the yoke 23. It is thus evident that these elements 22 are in ef- 59 feet cams for lifting the rack 19 in conjunction with the stay arms l3, this being accomplished as the diverging lower portions of the frames 1 and 8 are brought together during the process of collapsing or folding. The cross-piece 25, which ll includes the stop elements 18 on its ends, forms a convenient foot lifting element to facilitate collapsing. It follows that the basket rack l9 supported on the stay arms I3 is in eifect'the means for spreading and maintaining the leg frames in extended carrier forming positions.

I next call attention to the numerals 28 which designate hanger links. These links are pivotally mounted, as at 21, adjacent the handle 9. The lower ends 28 are formed into inturned suspension hooks to rockably support the foldable basket unit 29. It is to be understood that this basket can be built into the carriage or carrier or omitted as desired. When omitted, the rack at the bottom provides a convenient holder and transporting medium for an ordinary market basket. The preferred embodiment of the invenention, however, is to have the foldable basket 29 as a part thereof.

Considering the preferred embodiment of the basket 29, it will be seen that it comprises longitudinal side members and transverse end members. The upper and

lower rails

38 and 9| of the side walls or members are joined together by pivotally mounted wires 32 which form the desired retention elements. Similar wires 93 are connected to the U-shaped elements forming the foldable basket ends 35.

The numeral 38 unitarily designates the bottom of the basket, this including an open work grid of appropriate type, which grid includes longitudinal straps 31 to which the lower rails 3| of the basket 29 are rigidly connected. The upper curved ends of the legs 8 are pivotally attached as at 38 either to the members 3'! or directly to the lower part of the basket. Thus, the basket is fulcrumed on the upper ends of the legs 8 and is suspended on the pendulous links 21. The upper ends of the links pivotally join the up per corner portions of the basket, as indicated at 39, to provide the desired thrust action for collapsing the basket when the two frames i and 8 are folded together on the pivots l5. As seen in Figure 4, the suspended end of the basket is provided with a cross-rod 40 located in the bifurcated portions 4| of the hooks 28.

It is evident that with the basket set up, as seen in Figure 1, and the carriage expanded, the device is in readiness to be maneuvered in the store for convenient shopping. When it is desired to fold the structure to the position seen in Figure 3, all that is necessary is to lift up the stay arms l3 including the basket rack l9. Then forcing the lower diverging portions of the leg frames 1 and 8 together, this brings the upper portions into closing relationship and exerts a thrust on the pivot points 38 of the legs 8. This swings the basket rearwardly, that is, toward the user, tilting the links 26 on the pivots 21. In so doing the upper pivoted ends 39 exert a folding stress on the basket 29 and the whole basket collapses into compact form, as seen in Figure 3.

Substantially the same basic principle of construction is seen in the modification depicted in Figure 6. Thus, the same numerals are employed to designate corresponding parts.

In this arrangement instead of the basket folding forwardly and downwardly, as seen in Figures 1 and 3, it folds upwardly and backwardly. This is accomplished by pivotally supporting the collapsible basket, as a unit, at the points 42 on the main leg frame I. The upper ends of the legs 8 arehere shown as pivotally attached as at 42, the connection being made through the instrumentality of folding links 44 forming features of the basket. The numeral 45 merely designates a rigidly mounted handle which is designed to lift and facilitate folding and collapsing of the basket and leg structure.

It is desirable to interpret the conception as comprising a pair of leg frames I and 8 pivotally joined together in intersecting relation, as shown at IS in Figure l, the leg frames being roller supported, and there being stay devices I3 to limit the spreading of the diverging portions of said frames when expanded. Thus, in this simple phase of the invention we would have a folding carriage roller supported to accommodate an ordinary market basket. As before intimated, however, it is more desirable to have not only the rack I9, but to have built into the leg or carriage structure the collapsible or foldable basket 29. Hence, by properly suspending and pivotally mounting the collapsible basket on the upper complemental ends of-the leg frames, as said frames fold together, they exert simultaneous pressure for squeezing the readily foldable basket into its compact state, as seen in Figure 3. The same principle of operation is evident in Figure 6.

It is thought that the description taken in connection with the drawings will enable a clear understanding of the invention to be had. Therefore, a more lengthy description is thought unnecessary. I

while the preferred embodiment of the invention has been shown and described, it is to be understood that minor changes coming within the field of invention claimed may be resorted to if desired.
