A utility cart which is capable of being readily converted from a first configuration as a conventional utility cart with the area above a bottom table being open into a second configuration as a bin cart, including a number of outwardly extending storage bins. In addition, the utility cart in accordance with the present invention includes end members having “I” beam type construction, the top table and the bottom table have panel members which pivot from an upright position to form a recessed top table and/or a recessed bottom table to a downward position to form a substantially flat top table and/or a substantially flat bottom table and a handle having an organizer integrally built therein, including a beverage container holder, a storage tray and one or more storage compartments.

A toggle lever clamping device for tightening workpieces to a support frame, comprising: a box-shaped head having a longitudinal axis; a clamping arm pivotally connected at one end of the box-shaped head to rotate between open and closed conditions to lock respectively to release the workpiece; a linear actuator at the other end of the box-shaped head; and a toggle lever mechanism operatively connected between the actuator and the clamping arm; said toggle lever mechanism comprising an elastically yieldable connection link having a longitudinal axis extending between hinging ends, said toggle lever mechanism having a dead centre condition beyond which the connection link maintains the clamping arm tightened against the workpiece, wherein said elastically yieldable connection link comprises spaced apart stop means arranged to prevent an axial compression of the connection link upon reaching and overcoming said dead centre condition of the toggle lever mechanism, and wherein said stop means comprise first and second surface means oppositely arranged on confronting and angularly slanted contact planes. 4. A toggle lever clamping device according to claim 3, wherein the stop means comprise first and second stop members oppositely arranged and axially extending from the hinging ends of the connection link.5. A toggle lever clamping device according to claim 4, wherein one of the stop members comprises a contact element transversely and partially protruding extending from the front end of the same stop member of the clamping device.6. A toggle lever clamping device according to claim 4, wherein one of the stop members comprises a first and a second contact elements transversely extending and partially protruding from the front end of the same stop member of the clamping device.7. A toggle lever clamping device according to claim 6, wherein said first and second contact elements are in the form of contact members having a rounded peripheral surface.8. A toggle lever clamping device according to claim 7, wherein each of said first and second contact elements comprises a cylindrical member.9. A toggle lever clamping device according to claim 8, wherein said contact elements comprise a first contact member having a first diameter, and a second contact member having a second diameter lower than the previous one.10. A toggle lever clamping device according to claim 9, wherein the longitudinal axis of said first and second contact elements are laying in a same plane orthogonally arranged to the longitudinal axis of the connection link.11. A toggle lever clamping device according to claim 8, wherein said contact elements comprise a first and a second cylindrical contact members having a same diameter.12. A toggle lever clamping device according to claim 11, wherein the longitudinal axis of said first and second contact members are laying in a plane angularly arranged in respect to the longitudinal axis of the connection link.13. A toggle lever clamping device according to claim 6, wherein each of said first and second contact elements is fitted into a seating at the front end of a stop member.14. A toggle lever clamping device for tightening workpieces to a support frame, comprising: a box-shaped head having a longitudinal axis; a clamping arm pivotally connected at one end of the box-shaped head to rotate between open and closed conditions to lock respectively to release the workpiece; a linear actuator at the other end of the box-shaped head; and a toggle lever mechanism operatively connected between the actuator and the clamping arm; said toggle lever mechanism comprising an elastically yieldable connection link having a longitudinal axis extending between hinging ends, said toggle lever mechanism having a dead centre condition beyond which the connection link maintains the clamping arm tightened against the workpiece, wherein said elastically yieldable connection link comprises spaced apart stop means arranged to prevent an axial compression of the connection link upon reaching and overcoming said dead centre condition of the toggle lever mechanism, and wherein the connection link comprises a plurality of side by side arranged shaped steel plates. 15. A toggle lever clamping device according to claim 14, wherein each of said shaped steel plates of the connection link comprises hinging ends portions, first and second stop members parallely extending to the longitudinal axis of the connection link, and elastically yielding side arms to connect the end portions of the shaped steel plate.16. A toggle lever clamping device according to claim 15, wherein said side arms are in the form of inwardly arch shaped arms.17. A toggle lever clamping device according to claim 1, wherein the stop means provides a stop action via facing surfaces of a T-shaped slot.18. A toggle lever clamping device according to claim 1, wherein, the elastically compressible link is configured to be yieldable, at the beginning of the closing movement of the clamping arm, in the longitudinal direction of the connection link, and the stop means is conformed and arranged for first limiting the axial compression of the connection link upon reaching the dead center condition of the linkage when the clamping arm starts to urge against a workpiece, and to subsequently allow an angular deflection of the connection link, beyond the dead center condition of the toggle lever mechanism. 19. A toggle lever clamping device according to claim 18, wherein said stop means comprise first and second surface means oppositely arranged on confronting and angularly slanted contact planes.20. A toggle lever clamping device according to claim 18, wherein the connection link comprises a plurality of side by side arranged shaped steel plates.
