The spectacle frame has a front face, with two lateral stubs, and two temples which each extend from a front end, arranged against one of the front-face stubs, to a free rear end, each temple having on the inside a rod whose front end is immobilized at the front end of the temple, the temple having driving and shaping means for driving the movable rear end of the rod by displacement in the free rear end of the temple and for thus modifying the curvature of the temple. The front end of the rod is connected to the front-face stub against which is arranged the front end of the temple, inside of which the rod extends.

The frame includes a front surface (10) that is extended by two side tenons (12) and two arms (30) that are hinged onto the tenons (12) about the hinge axes (X-X′) of two hinges (50). The hinges (50) each include a front surface element (51) that rigidly connected to a tenon (12) and an arm element (52) that is rigidly connected to an arm (30). Each arm (30) is set up such as to pass, through rotation about said hinge axis (X-X′), from an open position for which said arm extends the tenon (12) to a closed position for which said arm is clamped into the front surface (10). In at least one of the hinges (50), the hinge axis (X-X′) is substantially perpendicular to the tenon (12) and to the arm (30).The front surface element (51) and the arm element (52) are set up such as to provide, between said tenon (12) and said arm (30), a space (60) for freely passing from the open position to the closed position.

Method of assembly of the shell with the strap of a clamping collar, and collars obtained with this method.This method consists in fixing the strap under the shell of the collar and no longer by passage inside the latter. With this in mind the shell (7) has, in the part forming its base (8), cut-outs preferably forming two tongues provided between remaining parts of the base. These tongues are cranked and the shell is fitted over the strap in a straddling position. The tongues are then flattened, the force applied preferably causing the corresponding strap portion (2) to penetrate by bending into the opening thus formed in the base of the shell. A non-slip bond is obtained between the shell and the strap owing to raised parts of the strap penetrating into the cut-out or opening in the base of the shell and forming immobilization stops. The invention also relates to the clamping collars thus obtained and a method of locking a collar in clamped position which consists in bending the strap portion emerging from the shell just beyond the latter, utilizing the space formed as a result of the fixation of the strap under the collar shell.

A clamping collar comprising an open ring (10), each end of which carries a bearing tab (10A, 10B), and tightening means comprising a tightening bolt (14) whose shank passes through the bores (12A, 12B) in the bearing tabs, a nut (16), and a spacer (18). In order to tighten the collar, the head of the bolt or the nut are driven in rotation. The spacer is disposed between the element that is driven in rotation and the corresponding bearing tab. The spacer (18) is formed by a rolled-up blank disposed around the shank (14B) of the bolt (14).

摘要:
An "open" type clamp constituted by a wound over metal strip 1, comprising two radial folds or ears 2-5, whereas a first ear is bent over and is provided with an extension directed along the periphery of the clamp to constitute a sole 4 which extends substantially over the distance separating the two ears. The second ear 5 has an extension 6 which is substantially parallel to the periphery of the clamp and extends as far as close to the first ear 2, comprising at its end a portion 7 bent towards the clamp.

This invention relates to a hose clamp constituted by a band of material, generally metal, wound on itself, one of the ends of said band presenting relief elements forming a rack, whilst on the other end is fixed a housing which constitutes the support of a screw which is mounted to pivot about its axis, said screw abutting on a stop axially mobile with respect to the housing against the action of a spring. The spring is constituted by a curved blade, for example in the form of a semi-circle, whose concavity faces the inside of the clamp and whose ends are laterally in contact with the sides of the housing. A first end of said blade is axially fixed to the housing and provided with an opening in which the tail of the screw may slide, whilst the second end of the blade surrounds at least partially the shank of the screw in the vicinity of its head and is mounted to slide with respect to the sides of the housing.
