Abstract
Abstract The elements of the frame, such as A, B, C, and D are held in place by the four angles (1) disposed at the corners of the frame and by the cramps (5, 6, 7, 8) mounted on each angle. On the other hand, each angle comprises a semi-circular flat sheave (1e) surrounding its right-angle apex. The edge of this sheave is provided with a groove (4) in which the cable (3) passes. The tightener (2) comprises a clamp (13) tightened by a screw (16) permitting the two strands of the cable (3) to be clamped between its body and its gripping part. The nut (23) bearing against the end side of the frame (10) acts upon the threaded rod (22) and exerts a pull on the clamp (13) through which the cable is tightened and the elements of the frame are squeezed tight against one another.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
245 words
An apparatus for assembling a plurality of side members to form a closed frame or panel in which adjacent side members are connected to one another to form corners, said frame or panel having the same number of corners as side members, said apparatus comprising: a plurality of angles, each angle embracing one of said corners, a guide means being provided in each of said angles; a cable having a central section, first and second ends, and two transitional sections connecting each of said ends to said central section, said central section of said cable passing within said guide means of each of said angles; a tightener having an elongated rectangular frame provided at one of its ends with two convergent force equilizing slideways, a movable clamp for firmly grasping said ends of said cable mounted on a slide, said slide being longitudinally slidably mounted on said frame, and an operating screw actuating said slide and clamp such that said cable is tightened about said angles by being drawn through said slideways when said operating screw is actuated relative to the frame in the longitudinal direction, said frame being constructed with at least two sides and said clamp being made up of a clamp body provided with guide means and mounted on said slide so that said clamp is able to slide longitudinally between the sides of said frame, and said clamp further having a jaw connected to said clamp body by a tightening screw.
Claim 2
Independent Claim
245 words

Claim 3
Dependent Claim
24 words
Apparatus according to claim 1, characterized in that said angles are each equipped with a cramp acting in a longitudinal direction of a angle.
Claim 4
Dependent Claim
45 words
Apparatus according to claim 2, characterized in that the cramps are each controlled by two screws, one of which is situated in an inside corner of the angle and is accessible by means of an elongated lateral opening contrived in an arris of said angle.
Claim 5
Dependent Claim
33 words
Apparatus according to claim 1, characterized in that the angles are made up of metal elements of sufficient length to be able to rest with one of their ends on a flat support.
Claim 6
Dependent Claim
54 words
Apparatus according to claim 4, characterized in that the angles are provided on their outside, all at the same height relative to their foot, with a thin sheave, said sheave having an arcuate outer edge having a groove serving to guide the cable, each angle being arranged in the outer edge of this sheave.
Claim 7
Dependent Claim
32 words
Apparatus according to claim 5, characterized in that the sheaves of the angles are provided with stirrup-pieces distributed along the groove and arranged, so as to hold the cable in said groove.
Claim 8
Dependent Claim
46 words
Apparatus according to claim 1, characterized in that the clamp body and the jaw each have two longitudinal grooves, with each one of said end segments of said cable being simultaneously fitted into opposed zones of said grooves, whereby the end segments are protected during clamping.
