Description

Description Title of the invention: FIXING AND SE- SYSTEM GREGATION Technical field

[0001] — The present invention relates to a fixing and segregation system allowing to fix two elements together while keeping them at a distance from each other the other. STATE OF THE PRIOR ART

[0002] In an aircraft, it often happens that cables or pipes must be fixed to each other, to keep them together but also to hold them separated from each other.

[0003] Currently, to ensure such segregation between two elements, it is known to use strings, generally nylon, and to make knots for example hangman's knot type, which requires making wraps around each element and make simple knots between the two elements to achieve the se- gregation. To limit the risk of the knot coming untied, it is necessary to burn the nylon to melt it.

[0004] Such an arrangement is therefore relatively long to implement and requires a good dexterity to make the knot.

[0005] It is therefore necessary to find an arrangement which makes it easier to fix and the segregation of two elements to improve productivity. Statement of the invention

[0006] — An object of the present invention is to provide a system for fixing and se- gregation which allows two elements to be fixed in relation to each other in a way simple and fast.

[0007] For this purpose, a fixing and segregation system is proposed for fixing between them a first element and a second element, said system comprising:

[0008] — - a shoe having a first recess and a second recess which are arranged on two opposite sides of the hoof and are open opposite each other and each recess being intended to receive one of the elements, where the shoe is crossed by a first tunnel and a second tunnel, where each tunnel of the hoof has a first opening and a second opening, where the first openings lead on either side of the first recess, and the second openings open from on either side of the second recess, and

[0009] — - a clamp collar having a flexible link and a cage secured to a first end of the link and having a tunnel for receiving a second end of the link, where the cage is equipped with a locking system allowing the link to move in the tunnel in a single direction, the second end of the link successively penetrating the first opening of the first tunnel, then the second opening of the second tunnel, then the tunnel of the cage. With such an arrangement, the two elements are easily and quickly attached to each other. Advantageously, each recess takes a concave arched shape. Advantageously, the hoof has at least one opening of a tunnel of the hoof, a housing intended to receive the cage, where the housing takes the form of a hollow of the hoof in the extension of said tunnel. Advantageously, each tunnel of the hoof takes an arched shape. Advantageously, for each tunnel, the center of curvature of said tunnel is arranged on the other side of said tunnel relative to the other tunnel. Advantageously, the shoe consists of a central piece, a first side piece and a second side piece, the side pieces are positioned on either side of the central piece, each side piece has one of the recesses and the openings opening out on either side of said recess, and each tunnel of the shoe is divided into three sections, one for the central piece and one for each side piece. Advantageously, for each pair of parts in contact with each other, one of the parts of the pair has at least one positioning pad and the other part of the pair has, for each positioning pad, a bore arranged to receive said positioning pad. Brief description of the drawings The above-mentioned and other features of the invention will become more clearly apparent from the following description of an exemplary embodiment, said description being made in relation to the attached drawings, among which: [Fig.1] shows a sectional view through a median plane of a fixing and segregation system according to the invention, [Fig.2] shows a sectional view of a first embodiment of a shoe implemented in the fixation and segregation system of [Fig.1], and [Fig.3] shows a sectional view of a second embodiment of a shoe implemented in the fixation and segregation system of [Fig.1]. DETAILED PRESENTATION OF EMBODIMENT METHODS [Fig. 1] shows a fixing and segregation system 100 according to the invention which is hereinafter referred to as the “system”. The system 100 makes it possible to fix a first element 10a and a second element 10b together while keeping them at a distance from each other. Each element 10a-b can take different shapes. Each element 10a-b may consist of one or more cables or pipes, or any other element to be fixed. The system 100 comprises a shoe 102 and a clamp 104. The cable tie 104 is made, for example, of plastic. It takes the form, for example, of a cable tie known as Ty-Rap ®. The clamp 104 comprises a flexible link 104a and a cage 104b secured to a first end of the link 104a. The cage 104b is crossed by a tunnel into which the second end of the link 104a is inserted. The cage 104b is equipped with a locking system allowing the movement of the link 104a in the tunnel in a single direction, called the tightening direction, and preventing the movement of the link 104a in the tunnel in a direction opposite to the tightening direction. According to a particular embodiment, the locking system comprises a ratchet system which is housed in the tunnel and teeth made on one of the faces of the link 104a. The teeth interact with the ratchet system to allow the movement of the link 104a in the tunnel in the tightening direction and prevent the movement of the link 104a in the opposite direction. According to a particular embodiment, the locking system can be releasable to release the link 104a in order to remove it from the tunnel. The shoe 102, a first embodiment of which is shown in [Fig. 2], has a first recess 106a and a second recess 106b which are arranged on two opposite sides of the shoe 102, that is to say opposite each other with respect to a plane P called the middle plane. Each recess 106a-b is open opposite the other recess 106b-a and therefore the middle plane P to receive an element 10a-b to be secured. In the embodiment of the invention shown in Figs. 1 and 2, each recess 106a-b takes a concave arcuate shape to best accommodate the elements 10a-b of circular section and the shoe 102 here generally has the shape of an X. The shoe 102 is crossed by a first tunnel 108a and a second tunnel 108b which are arranged opposite each other with respect to a plane C called the central plane which is perpendicular to the middle plane P. The tunnels 108a-b of the shoe 102 are arranged on either side of the central plane C. In Figs. 1 and 2, the first tunnel 108a is above the central plane C and the second tunnel 108b is below the central plane C. Each recess 106a-b extends on either side of the central plane C. Each tunnel 108a-b of the shoe 102 has a first opening 110a, 112a associated with the first recess 106a and a second opening 110b, 112b associated with the second recess 106b. The first openings 110a and 112a open on either side of the first recess 106a. The second openings 110b and 112b open on either side of the second recess 106b. The installation of the system 100 consists of placing the shoe 102 between the two elements 10a-b by placing the first element in the first recess 106a and the second element 10b in the second recess 106b. The second end of the link 104a is introduced into the first opening 110a of the first tunnel 108a, that is to say the one which is on one side of the first recess 106a, and the second end of the link 104a therefore exits through the second opening 110b of the first tunnel 108a, that is to say the one which is on one side of the second recess 106b. The second end of the link 104a then goes around the second element 10b to be introduced into the second opening 112b of the second tunnel 108b, that is to say the one which is on the other side of the second recess 106b, and the second end of the link 104a therefore exits through the first opening 112a of the second tunnel 108b, that is to say the one which is on the other side of the first recess 106a. The second end of the link 104a then goes around the first element 10a to be introduced into the tunnel of the cage 104b.The second end of the link 104a is then pulled to bring the cage 104b against the first opening 110a of the first tunnel 108a and to tighten the link 104a around the two elements 10a-b which are then pressed against the walls of the shoe 102 delimiting the recesses 106a-b. The installation of the system 100 is then simple and rapid and the two elements 10a-b are then held together and kept at a distance from each other. Each tunnel 108a-b of the shoe 102 here takes an arcuate shape to avoid protruding angles which could damage the link 104a and limit the friction of the link 104a on the shoe 102. In the embodiment shown in Figs. 1 and 2, for each tunnel 108a-b, the center of curvature of said tunnel 108a-b is disposed on the other side of said tunnel 108a-b relative to the other tunnel 108b-a. Such an arrangement also makes it possible to orient the link 104a so that the parts of the link 104a which are outside the shoe 102 take a circular shape which best surrounds the elements 10a-b. The shoe 102 has at least one opening of a tunnel 108a-b of said shoe 102, here the first opening 110a of the first tunnel 108a, a housing 202 intended to receive the cage 104b. The housing 202 takes the form of a hollow in the shoe 102 in the extension of the first tunnel 108a. The opening where the housing 202 is present constitutes the first opening into which the second end of the link 104a is inserted. In the embodiment of the invention shown in Figs. 1 and 2, the shoe 102 is made of a single piece. In the embodiment of the invention shown in [Fig. 3], the shoe 302 is made of three pieces 304, 306a-b which can be separated from each other in order to produce a modular shoe 302. [Fig.3] also shows a median plane M appearing on the section plane of Figs. 1 and 2. The shoe 302 thus comprises a central part 304, a first lateral part 306a and a second lateral part 306b. Each side piece 306a-b comprises one of the recesses 106a-b and the openings 110a-b, 112a-b opening out on either side of said recess 106a-b. Each tunnel 108a-b of the shoe 302 is divided into three sections 308a-b, one for the center piece 304 and one for each side piece 306a-b. When the three pieces 304 and 306a-b are in place, the sections are aligned to form the tunnels 108a-b of the shoe 302. The side pieces 306a-b are positioned on either side of the central piece 304 and bearing against the latter and depending on the length of the central piece 304, the distance between the recesses 106a-b can be modified as required. The central piece 304 and each side piece 306a-b are applied against each other at contact planes 310a-b that each piece 304, 306a-b has for this purpose and which is here parallel to the middle plane P. When the link 104a is put in place and tightened, the three parts 304 and 306a-b are held against each other by tightening. To assist in the correct positioning of the parts 304 and 306a-b with respect to each other, a first part (here the central part 304) has at least one positioning stud 312 and a second part (here each lateral part 306a-b) which is against the first part has, for each positioning stud 312, a bore 314 arranged to receive said positioning stud 312. In other words, for each pair of parts 304, 306a-b in contact with each other, one of the parts of the pair has at least one positioning stud 312 and the other part of the pair has, for each positioning stud 312, a bore 314 arranged to receive said positioning stud 312.
