A room service table includes a frame, a tabletop including folding side portions and wheels. A push handle assembly mounts to an underside of the table and includes a handle portion and a hinge body portion. The handle portion includes a grip, a support portion and a hinge pin portion. The hinge body mounts to the tabletop and includes barrel portions supporting the hinge pin portion. The hinge pin portion has a tab formed in an end thereof engaging a complementary slot formed in the hinge body portion. The slot includes a first section and a second section that receive and retain the tab for aligning and securing the handle at the use position and at the storage position. The biasing member urges the pin toward the slot. Rotation is accomplished by sliding the handle axially so that the tab disengages the slot and rotating the handle to the desired position and then releasing the handle.

What is claimed is: 1. A room service table, comprising: a frame; rolling devices supporting the frame; a tabletop mounted to the frame; a rotatable push handle assembly rotating between a use position and a storage position, the assembly including: a handle; a hinge assembly having a body, a pin and a biasing element, the body mounting to an underside of the tabletop, the pin connected to the handle, wherein the pin slides axially in the body between a first position wherein the handle is locked and a second position wherein the handle freely rotates and the biasing element urges the pin toward the first position; wherein the hinge body comprises an inner wall having a portion extending unobstructed substantially along the length of the pin body. 2. A room service table according to claim 1, further comprising a pin detent locking the handle only at the use position and at the storage position. 3. A room service table according to claim 1, wherein the handle extends above the tabletop at the use position and extends below the tabletop in the storage position. 4. A room service table according to claim 1, further comprising a pin detent locking the handle at the use position and at the storage position, wherein the pin detent comprises a tab on one of the pin or the body and a complementary slot formed in the other of the pin or the body. 5. A room service table according to claim 1, further comprising a pin detent locking the handle at the use position and at the storage position wherein the pin detent comprises a tab extending from an end of the pin and a complementary slot formed in the pin body. 6. A room service table according to claim 5, wherein the slot comprises a first section configured for receiving the tab when the handle assembly is at the use position and a second section configured for receiving the tab when the handle assembly is at the storage position. 7. A room service table according to claim 1, wherein the biasing element is positioned in the body and engages an end of the pin. 8. A room service table according to claim 1, further comprising a pin detent locking the handle only at the use position and at the storage position, wherein the pin detent comprises a tab extending from the pin and a complementary first engagement portion formed in the pin body configured for receiving the tab when the handle assembly is at the use position and a complementary second engagement portion configured for receiving the tab when the handle assembly is at the storage position. 9. A room service table according to claim 1, wherein the hinge assembly pin comprises spaced apart axially aligned first and second pins rotationally mounted in complementary first and second spaced apart hinge bodies, a biasing element mounted in the first hinge body proximate a first end of the first pin opposite the second pin and biasing the first pin toward the second pin. 10. A room service table according to claim 9, wherein the second pin comprises an end portion extending from a second end away from the first pin and engaging a complementary receiving portion formed at an end of the second hinge body. 11. A room service table according to claim 1, wherein the pin body comprises an end portion having a width smaller than the width of the pin body. 12. A room service table according to claim 1, wherein the hinge body comprises a monolithic element. 13. A handle apparatus for a room service table, comprising; a rotatable push handle assembly rotating between a use position and a storage position, the assembly including: a handle; a hinge assembly having spaced apart axially aligned first and second pins connected to the handle and rotationally mounted in complementary first and second spaced apart hinge bodies configured for mounting to an underside of a room service table tabletop, a biasing element mounted in the first binge body proximate a first end of the first pin opposite the second pin; wherein the pin slides axially in the body between a first position wherein the handle is locked and a second position wherein the handle freely rotates and wherein the biasing element biases the first pin toward the second pin. 14. A handle apparatus according to claim 13, further comprising a biasing element biasing the pin toward the first position. 15. A handle apparatus according to claim 14, further comprising a pin detent locking the handle at the use position and at the storage position. 16. A handle apparatus according to claim 14, further comprising a pin detent locking the handle at the use position and at the storage position wherein the pin detent comprises a tab on one of the pin or the body and a complementary slot formed in the other of the pin or the body. 17. A handle apparatus according to claim 14, further comprising a pin detent locking the handle at the use position and at the storage position, wherein the pin detent comprises a tab extending from an end of the pin and a complementary slot formed in the body. 18. A handle apparatus according to claim 17, wherein the slot comprises a first section configured for retaining the tab when the handle is at the use position and a second section configured for retaining the tab when the handle is at the storage position. 19. A handle apparatus according to claim 14, wherein the biasing element is positioned in the body and engages an end of the pin. 20.
