Frame assembly

Claim 3

The connecting device defined in claim 1 wherein the frame element is of circular section and the recesses are of complementary shape but slightly less than semicylindrical.

Claim 4

The connecting device defined in claim 1 wherein the bridge is formed with a plurality of such pairs of hooks.

Claim 5

The connecting device defined in claim 1 wherein the body is formed of two relatively displaceable and fixable parts.

Claim 6

The connecting device defined in claim 4 wherein the two body parts are pivoted together.

Claim 7

The connecting device defined in claim 1 wherein the means for securing is a bolt engaged in the support.

Claim 8

The connecting device defined in claim 6 wherein the bridge is rotatable on the bolt.

Claim 9

The connecting device defined in claim 1 wherein the traction means is a threaded fastener engaged between the inner ends of the jaws and extending across the inner split.

Claim 10

The connecting device defined in claim 1, further comprising a flexible tie engaged between the outer ends of the jaws and extending across the outer slit.

Claim 11

A frame assembly comprising: an elongated frame element; a generally stationary support; a pair of like elongated clamping jaws extending generally parallel to and spaced from each other, having inner and outer ends, and formed with confronting recesses embracing the element with the jaws separated by inner and outer slits extending oppositely from the recesses toward the respective ends of the jaws, the outer ends of the jaws being formed with respective oppositely directed ribs; traction means connected between the inner ends of the jaws for drawing the jaws together at the inner slit while urging the jaws and ribs apart at the outer slit and for thereby clamping the element between the jaws; and a bridge having a pair of sides one of which is formed with a pair of confronting and relatively nondisplaceable hooks engaging over the ribs, whereby spreading of the jaws at the ribs engages the jaws tightly in the bridge, the other side being formed with a pair of spaced arms extending away from the one side and embracing the support, the hooks and arms being integral and the bridge being limitedly elastically flexible so that as the jaws are urged apart by the ribs the arms move together and tightly grip the support.

Claim 12

A frame assembly comprising: an elongated frame element; a generally stationary support; a pair of like elongated clamping jaws extending generally parallel to and spaced from each other, having inner and outer ends, and formed with confronting recesses embracing the element with the jaws separated by inner and outer slits extending oppositely from the recesses toward the respective ends of the jaws, the outer ends of the jaws being formed with respective oppositely directed ribs; traction means connected between the inner ends of the jaws for drawing the jaws together at the inner slit while urging the jaws and ribs apart at the outer slit and for thereby clamping the element between the jaws; and a bridge having a pair of sides one of which is formed with a pair of confronting and relatively nondisplaceable hooks engaging over the ribs, whereby spreading of the jaws at the ribs engages the jaws tightly in the bridge, the other side being formed with a pair of spaced arms extending away from the one side and embracing the support, the hooks and arms being integral and the bridge being limitedly elastically flexible so that as the jaws are urged apart by the ribs the arms move together and tightly grip the support.

Claim 13

The frame assembly defined in claim 10 wherein the support is formed with a respective pair of such ribs directed away from each other and the arms are formed as such hooks engaged over the ribs of the support.
