Supporting collar
View Patent ↗Supporting collar ( 10 ) for an element ( 8 ) such as a cable or a pipe, comprising a strap ( 18 ) capable of being fixed to a support ( 12 ), an outer sleeve ( 16 ) encircled by this strap ( 18 ), an inner sleeve ( 14 ) through which said element ( 8 ) can pass, and a deformable web ( 15 ) connecting said sleeves ( 14, 16 ) and allowing the inner sleeve ( 14 ) to move relative to the outer sleeve ( 16 ). The outer sleeve ( 16 ), the web ( 15 ) and the inner sleeve ( 14 ) are formed as a single central part made of an elastomeric material, e.g. fluorosilicone. The element ( 8 ) is secured to the inner sleeve ( 14 ) with the aid of a fastening collar ( 20 ) that is fastened around the inner sleeve ( 14 ).
1. A supporting collar for an element such as a cable or a pipe, comprising a strap capable of being fixed to a support, an outer sleeve encircled by said strap, an inner sleeve through which said element can pass, and a deformable web connecting said inner and outer sleeves and allowing the inner sleeve to move relative to the outer sleeve, said deformable web being formed by two annular membranes that come together at the outer sleeve and diverge with distance from the outer sleeve so that said deformable web, in cross section, is generally Y-shaped, having a base joined to said outer sleeve and two arms spreading out and joined with said inner sleeve at two junctions.
2. A supporting collar according to claim 1 , wherein said annular membranes extend to blend with the inner sleeve at said two junctions.
3. A supporting collar according to claim 1 , wherein said annular membranes extend to encircle the inner sleeve at said two junctions.
4. A supporting collar for an element, said supporting collar comprising:
a strap fixable to a support;
an outer sleeve encircled by said strap;
an inner sleeve configured to receive said element;
a deformable web connecting said inner and outer sleeves and allowing the inner sleeve to move relative to the outer sleeve, said deformable web comprising two annular membranes that come together at the outer sleeve and diverge with distance from the outer sleeve; and
at least one fastening collar capable of being fastened around the inner sleeve.
5. A supporting collar according to claim 1 , wherein the web is relaxed when the supporting collar is at rest.
6. A supporting collar according to claim 1 , wherein the web is made of an elastic material.
7. A supporting collar according to claim 1 , wherein a rib is formed on the outer face of the outer sleeve to house said strap.
8. A supporting collar according to claim 1 , wherein the outer sleeve, the web and the inner sleeve form a single central part.
9. A supporting collar according to claim 8 , wherein said central part is made of fluorosilicone.
10. A supporting collar according to claim 8 , wherein said central part has a slit extending from the inside of the inner sleeve to the outside of the outer sleeve.
11. A supporting collar according to claim 1 , wherein said strap is preformed for snug contact with practically the entire outer circumference of the outer sleeve.
12. A supporting collar according to claim 10 , wherein said strap is preformed for snug contact with practically the entire outer circumference of the outer sleeve.
13. A supporting collar according to claim 1 , wherein said two arms of said deformable web spread out so as to define an annular cavity between said two arms and said element when said element is in said inner sleeve.
14. A supporting collar according to claim 1 , wherein said inner and outer sleeves have a common axis of revolution, and wherein said inner sleeve has a length along said axis of revolution that is greater than a length of said outer sleeve along said axis of revolution.
15. A supporting collar according to claim 1 , wherein said two annular membranes diverge with a curvature.
16. A supporting collar according to claim 4 , wherein said element is a cable.
17. A supporting collar according to claim 4 , wherein said element is a pipe.
