The present invention relates to a fixing method for assembling together a number of plates (or objects @ indeterminate giving a known or evaluated thickness
This type of fixing is traditionally obtained on screw-nut or screw-screw systems requiring the use of several parts and / or special tools
This invention overcomes this drawback
Indeed, a single piece, a seat tool a single gesture are the characteristics of the adjustable clip cannot be dismantled
On the other hand, in the case of a screw-nut system, it is necessary to have access to both sides of the plates or objects to be fixed. An access side is necessary for the use of the adjustable removable clip.

The fastener according to the invention comprises two parts, one fixed A, the other mobile C, intended to cooperate with one another.
Les deux parties sont fabriquées d'une seule pièce donc reliées entre elles par des liaisons cassables lors de la mise en mollve- ment de C par rapport a A.The two parts are made in one piece, therefore linked together by breakable connections when C is molten with respect to A.
La partie A comporte deux pattes extérieures B (ou tout autre moyen de non rotation de A@ et deux plans helicoidaux d'élévation en son diamètre intérieur (ou tout autre moyen d'élévation)
La partie C comporte un clip déformable å l'une de ses extrémités; une fente pour tournevis ou autres formes par clès six pans et deux ailettes K à l'autre de ses extrémites,
Les ailettes K sont raccordées par des l @aisons cassables ? au diamètre intérieur de la partie A.Part A has two outer legs B (or any other means of non-rotation of A @ and two helical elevation planes in its internal diameter (or any other means of elevation)
Part C has a deformable clip at one of its ends; a slot for a screwdriver or other forms by hexagon wrench and two vanes K at the other of its ends,
Are the fins K connected by breakable connections? the inside diameter of part A.
Le dessous des ailettes K a une forme hélicotdale d'une valeur compatible à celle des deux plans helicoidaux crantés d'elévation. The underside of the fins K has a helicoidal shape of a value compatible with that of the two notched helical planes of elevation.
Le CLIP REGLABLE INDEMONTABLE est composé
D'une rondelle A( diametre'exterieur X, diametre interieur Y épaisseur Z
Sur cette rondelle deux pattes extérieures B A l'intérieur de la rondelle deux port ions de plans helicoidaux crantes D'un axe central C de diam X ' comportant a a tine de ses extrèmitès deux aliettes K ( symètrique entre elles , le dessous de chaque ailette a un profil identique d a valeur de l'hèlice réalisée sur les deux portions de plais néllcoidaux crantés; et une fente, permettant l'accès a un tournevis ou de toute autre forme permettant le positionnement d'un seul outil ( clé six pans , etc )
A l'autre extrémité de l'axe C se trouve un clip déformable
L'axe central C et la rondelle A sont reliés entre eux et. ne forment qu'une seule et mème pléce grace aux raccordements D joignant le diametre interieur Y de A et les deux ailettes K de l'axe C.The ADJUSTABLE ADJUSTABLE CLIP is made up
A washer A (outside diameter X, inside diameter Y thickness Z
On this washer two external legs BA inside the washer two port ions of notched helical planes With a central axis C of diam X 'comprising at its end two fins K (symmetrical between them, the underside of each fin has an identical profile of the value of the propeller produced on the two notched nellcoidal pleasure portions; and a slot, allowing access to a screwdriver or any other form allowing the positioning of a single tool (hexagon wrench, etc.)
At the other end of the C axis is a deformable clip
The central axis C and the washer A are interconnected and. form only one and the same part thanks to the connections D joining the internal diameter Y of A and the two fins K of the axis C.

aiguilles d'une montre
Sous l'effort de rotation des deux raccordement s D sont cisaillés. les 2 ailettes K de l'axe central C arrivent en appui sur les 7 partions de plans hélicoidaux crantés et sous l'effort de rotation . élévent l'axe central de façon à réduire la distance C jusqu'au serrage des plaques E et F
Les deux portions de plans hélicoidaux crantés permettent: a- d'obtenir un serrage de précision dans le cas ou l'épaisseur

connue b- un intervalle de tolérance sur l'épaisseu@ totale des plaquettes et un règlage de la pression de serrage dans la limite de l'élasticité de la matière utilisée c- d'obtenir une immobilisation et une indémontabilite
En cas de rupture des 7 raccordements Il avant utilisation , le clip n'est pas perdu . il suffit d'enfoncer l'axe central C et de recupérer la rondelle A

Under the rotational force of the two connections s D are sheared. the 2 fins K of the central axis C come to bear on the 7 portions of notched helical planes and under the force of rotation. raise the central axis so as to reduce the distance C until the plates E and F are tightened
The two portions of notched helical planes allow: a- to obtain a precise tightening in the case where the thickness
total of platelets E and F @ non-limiting non-limiting; East

EXEMPLE NON LIMITATIF
En partant sur l'hypothèse de 12 crans par portion de plan hélicoïdal crantés
Valeur d'élévation par cran : 0,2 mm
Cote G = 10 ( valeur entre clip et face d'appui sous rondelle A)
Cote H = 1 1.5( valeur de l'hélice sous ailettes K
Cote ET = 6 ( épaisseur totale
Cote J = 1,5 ( départ du premier cran sur A
Nous pouvons fixer toute une gamme d'épaisseur totale ET allant de ET max = G-n- j
10- 1,5 - 1.5
= fmm à ET mini = G-H-J- (12 x 0.2 10-1,5-1,5-2,4
= 4, 6 mm
Dans ce cas le CLIP selon l'invention est réglable de 0,2 mm en 0,2 mm dans une épaisseur totale allant de 4,6 à 7 mm
Nota . toutes les cotes sont modulables
VARIANTES
On peut assimiler la rondelle A a tout autre support . Ainsi une pièce de forme quelconque et de fonction différente à la rondelle
A , devant fixer ou être fixée à une ou plusieurs plaques ou objets , peut être étudiée en noyant dans son épaisseur un clip selon l'invention.- The cut @ represents the profile of the allettes K at one of the
C axis ends
NON-LIMITING EXAMPLE
Starting on the assumption of 12 notches per portion of notched helical plane
Elevation value per notch: 0.2 mm
Dimension G = 10 (value between clip and support face under washer A)
Dimension H = 1 1.5 (value of the propeller under fins K
Dimension ET = 6 (total thickness
Dimension J = 1.5 (start of the first notch on A
We can fix a whole range of total thickness ET going from ET max = Gn- j
10- 1.5 - 1.5
= fmm at ET mini = GHJ- (12 x 0.2 10-1.5-1.5-2.4
= 4.6 mm
In this case the CLIP according to the invention is adjustable from 0.2 mm to 0.2 mm in a total thickness ranging from 4.6 to 7 mm
Note. all dimensions are flexible
VARIANTS
We can assimilate the washer A to any other support. So a piece of any shape and different function to the washer
A, having to fix or be fixed to one or more plates or objects, can be studied by drowning in its thickness a clip according to the invention.
D'autre part il est évident qu'il n'y a pas de limite dimentionnelle au clip selon l'invention et qu'il peut. être réalisé soit sur commande spéciale soit sur gamme de dimensions standards

LA FABRICATION
A titre d'exemple on donne ci-dessous des procédés de fabrication ( non exhaustif )
Le procéd de fabrication est l'injection plastique , nécessitant a fabrication d'un moule métalique a une ou plusieurs empreintes.THE MAKING
As an example we give below manufacturing processes (not exhaustive)
The manufacturing process is plastic injection, requiring the fabrication of a metal mold with one or more cavities.
Ce type de transformation plastique nous permet d'obtenir des produits finis en une seule pièce . I1 est possible de changer la nature du matériau en fonction des caractéristiques mécaniques chimiques et thermiques demandées . Tout thermoplastique est envisageable De méme la méthode de fabrication peut être autre que l'injection plastique ; cependant seul ce procédé assure une homogénéité des caractéristiques mécaniques et chimiques (arrangement des chaines moléculaires)
Bien qu'un des avantages de l'invention soit d'être en une seule et mème pièce on peut envisager sa fabrication en plusieurs parties This type of plastic transformation allows us to obtain finished products in one piece. It is possible to change the nature of the material as a function of the mechanical, chemical and thermal characteristics requested. Any thermoplastic is possible. Similarly, the manufacturing method can be other than plastic injection; however, only this process ensures homogeneity of mechanical and chemical characteristics (arrangement of molecular chains)
Although one of the advantages of the invention is that it is in a single piece, it can be envisaged to be made in several parts
