Theserivets-46 are provided with 3 substantially rectangular head portions 54 that slidably engage longitudinal slots 56 provided in a pair of side elements or straps 56.

Further guide pins 66 are also fixed to the sid sections 36 and 44 and engage these slots 56 to permit only longitudinal movement of the straps relative to the side sections 36 and 44.

Threaded studs integral with the heads or guides 54 receivably engage wing nuts 62 which are adjustable to bear against the straps 58 in order to adjustably retain the straps 58 in a selected extended position relative to the side sections 36 and 44.

An auxiliary, substantially channel shaped uide 64 is fixed to the side section 36 and slidably receives and supports the longitudinal movement of the strap 58 relative to the said side section 36.

A pair of slidably engaged concaval convexed hand gripping sections 66 and 68 are provided with reduced arcuate or looped outer terminals I6 that engage notches I2 in the upper ends of the straps 58 and openings or apertures I4 adjacent the upper ends of the straps 58, for pivotal movement of the straps 58 relative to the hand grips 66 and 68.

To prevent disengagement of the hand grips 66 and 68 from each other, there is provided a pair of detents or lugs I6 which are integral with one of the grips and which bear against the remaining grip.

A transverse bar I8 is fixed by welding or the like to the central portion of the inner section I2, between the pads or strips 26, and includes outwardly projecting terminal hooks 86 that will engage headed bolts or fasteners 82 that are removably carried by one end wall 84 of a suitcase or baggage 86.

Reference is now directed to Figures 5 and 6, wherein there is disclosed the wheeled frame portion of the present invention, which is designated generally by the numeral 88.. This wheeled frame 86 includes inner and outer sections 86 and 82 one of which, for example section 86 supports a plurality of guide pins 84 that slidably engage a guide opening or slot 86 provided in the remaining section, namely. section 82.

Pins 88 and I66 project from the section 86 and 82 to engage the ends of an elongated, resilient member or coil spring one of two that urges the sections 86 and 82 inwardly toward each other.

A pair of longitudinally spaced resilient pads I64 having serrated or toothed bearing surfaces are suitably fixed to the inner section 96 and a transverse anchor plate I66 is rigidly attached to the central portion of the inner section 86 and includes terminal hooks I68 that engage headed bolts (similar to 82) which are removably secured to the suitcase 86 with the pads I64 bearing against the said suitcase.

Laterally projecting arms H6 and H2 are integrally formed with the inner and outer sections 86 and 82 respectively, and are notched as at II4 to pivotally engage the reduced ends I I6 of a pair of holding members I I8.

Bearing pads I26 are fixed in any suitable manner to the members I I8 and bear against the outer surface of the suitcase 86, as shown best in Figure 1 of the drawings.

Transverse slots I22 are provided adjacent the outer ends of the sections 86 and 82, and the slots I22 pivotally engage the reduced ends I24 of a pair of side sections or members I26 which support stub axles I28 for rubber tired wheels I 36.

Plates I32 are fixed to the side members I26 and support resilient pads I34 having toothed or serrated bearing surfaces that will engage the outer surface of the suitcase 86.

In practical use of the present invention, the side sections 36 and 44 of the handle structure I6 are pulled outwardly away from each other and placed on opposite sides of the suitcase 86. The spring 26 will urge the said side sections 36 and 44 inwardly to bear against the outer faces of the suitcase 86, and the terminal hooks 86 are engaged with the fasteners 82 to prevent movement of the handle structure I6 relative to the suitcase. The wing nuts 62 are tightened when the hand grips 66 and 68 are disposed at a selected extended position relative to the sections I2 and I4.

The side sections or members I26 of the wheeled frame 88 are also pulled outwardly away from each other and are disposed on opposite sides of the suitcase 86, and diagonally from the handle structure I6 with the bearing elements I26 engaging the lower face of the suitcase 86, as shown best in Figure 1 of the drawings. The terminal hooks I68 of the anchor plate I66 are engaged with suitable fasteners 82 (not shown) which are secured to the normally lower or bottom wall of the suitcase 86.

It should be noted that the handle structure I6 may be placed in a selective position on the sui-t case 86, so that the hand grips 66 and 68 may cooperate with the wheeled frame 88 to support the suitcase 86 in an upright, substantially vertical position and raised above the ground surface or floor surface on which the wheels I36 and grips 66 and 68 bear.

Reference is now directed to Figure 9, wherein there is disclosed the wheel supporting frame in slightly modified form. In this embodiment, an angle member I36 is rigidly secured or removably secured by rivets, fasteners or the like to the lower corners of the suitcase 86. Stub axles I38 will project outwardly from the angle members I36 to support a suitable wheel similar to that disclosed by the numeral I36.

Figure 10 illustrates a modified embodiment of the handle supporting frame that will replace the inner and outer sections I6 and I2 and the side sections 36 and 44 pivotally secured thereto. This handle supporting element or handle member I46 is provided with a pair of integral guides or L-shaped brackets I42 that will slidably engage the straps 58. Projecting outwardly from the member I46, is an externally threaded rod or bolt I44 that receives the guide slots 56 provided in the straps 58. A holding nut I 46 and washer I 48 are received on the bolt I44 and bear against the outer surface of the straps 58 to retain the said straps in a longitudinally adjusted position relative to the member or members I46.

It is obvious that the members shown in Figures 9 and 10 of the drawings are employed when it is desirable to manufacture a suitcase having a wheeled frame and handle structure permanently applied thereto. However, the said members I36 and I46 may be removably secured to a suitcase by merely inserting fasteners or the like through openings or apertures which are suitably provided in the said members.

Although illustrated in the drawings, the handle structure I6 is composed of sections which are hinged or pivoted together in a particular manner, it is obvious that the same could be so connected to each other as to permit the said handle construction to be completely collapsed, for shipment, transport or the like.

The above is likewise-truafon the heeled frame; 38 and it is obvious that the endsections in which instance it would notbe necessary to employ the anchoring members or fasteners 82.

In -view of the foregoing description takenin conjunctionwith. the accompanying drawings it isbelieved that acleaivund'erstanding of the construction, operation and advantages of the device will be quite apparent to those skilled in this art. A more detailed description is accordingly deemed unnecessary.
