Abstract

The wedge is a section of plastics or metallic material which is triangular in cross-section. Its tip (1) has an acute angle and it has two flat surfaces (2,3) which are oblique and overlap. The wedge penetrates into the groove in the frame and is pushed in by pressure of the thumb on the upper surface (3).The inner surface (2) is pressed against the side (4) of the section when the wedge is pushed in. The point and the inner surface form springs which lock the wedge in position.

Description

La cale en pointe ayant pour effet la fixation du cadre autour du châssis de la toile est un profilé en matière plastique ou métallique de section triangulaire dont le sommet est un angle aigu (I) et dont l'ouverture comporte deux plans ou méplats (2 et 3) rabattus pour se chevaucher en oblique. The wedge at the point having the effect of fixing the frame around the chassis of the canvas is a plastic or metallic profile of triangular section whose apex is an acute angle (I) and whose opening comprises two planes or flats (2 and 3) folded down to overlap obliquely.

Ce dispositif est destiné à s'enfoncer dans la feuillure du cadre par l'interstice disponible autour du châssis de la toile. La pression du pouce sur le rabat supérieur (3) introduit par force la cale qui s'articule autour de ses deux ressorts, l'un par l'articulation de l'angle aigu (I) et l'autre par le pliage du rabat intérieur (2) contre le côté (4) qui est l'une des deux parois ou côtés du triangle réalisant une cale en pointe. This device is intended to sink into the rebate of the frame through the gap available around the canvas frame. The pressure of the thumb on the upper flap (3) forcibly introduces the shim which is articulated around its two springs, one by the articulation of the acute angle (I) and the other by the folding of the flap interior (2) against the side (4) which is one of the two walls or sides of the triangle forming a wedge point.

Le dispositif s'articule en s'enfonçant par force, avec un effet de ressort, par le pliage du rabat intérieur (2) contre le côté (4) en verrouillant le calage. En effet, le rabat (2) renforce l'élasticité de l'angle aigu en s enfonçant comme une seconde cale entre les parois du dispositif. Cet effet de double ressort renforce donc le calage pour une bonne fixation du tableau. The device is articulated by sinking by force, with a spring effect, by folding the inner flap (2) against the side (4) by locking the wedging. Indeed, the flap (2) strengthens the elasticity of the acute angle by sinking like a second wedge between the walls of the device. This double spring effect therefore reinforces the setting for a good fixing of the table.

Par ailleurs, ce dispositif s'adapte à la normalisation relative et aléatoire de l'écart entre les dimênsions du châssis et celles du cadre, écart dans la profondeur de la feuillure qui est une entaille pratiquée dans le cadre pour la réception du châssis qui vient s'y encastrer. Cette adaptation est consécutive au jeu du rabat intérieur assurant l'élasticité requise pour compenser la variabilité de l'intervalle autour du châssis. In addition, this device adapts to the relative and random normalization of the gap between the dimensions of the chassis and those of the frame, gap in the depth of the rebate which is a notch made in the frame for the reception of the chassis which comes fit into it. This adaptation is consecutive to the play of the inner flap ensuring the elasticity required to compensate for the variability of the interval around the chassis.

le rabat intérieur (2) assure le verrouillage du dispositif par pression contre les parois du profilé en agissant comme une seconde cale à l'intérieur de la première. Des striures d'un relief conséquent sont pratiquées sur les parois pour renforcer la fixation du châssis après le cadre. Enfin, le dispositif s'adapte à toutes les profondeurs de feuillure d'usage courant. the inner flap (2) locks the device by pressing against the walls of the profile by acting as a second wedge inside the first. Striations of a consequent relief are practiced on the walls to reinforce the fixing of the frame after the frame. Finally, the device adapts to all the standard rabbet depths.

Claims

R E V E F-D I C A T I O N S

I. Profile in plastic or metallic material characterized by its triangular section whose apex is an acute angle (I) and whose opening comprises two planes or flats (2 and 3) folded down to overlap obliquely. This device is a wedge at a point intended to sink into the rebate of the frame through the gap available around the canvas frame. The pressure of the thumb on the upper flap (3) forcibly introduces the wedge which is articulated around its two springs constituted respectively by the acute angle and by the folding of the inner flap (2) against the side (4). This double articulation acts like a spring and acts like a second wedge between the walls of the profile.

2. Plastic or metallic profile according to the preceding claim characterized in that this fixing device adapts to the relative and random standardization of the difference in dimensions between the frame and the chassis. This adaptation is effected by the spring effect of the inner flap which ensures the locking of the device acting as a second wedge inside the first. the device adapts to all standard rabbet depths.

Striations of a consequent relief are practiced on the walls to reinforce the fixing.
