Abstract

A retainer for connecting two panels of a heat shield assembly, the retainer comprising: a central elongate panel having a length l and a width w, a top end, a bottom end and first and second long sides extending from the top end to the bottom end; a first side panel extending along the first long side of the central elongate panel and a second side panel extending along the second long side of the central elongate panel; and wherein reinforcement features are applied to a surface of the central elongate panel.

First claim

What is claimed is:

1 . A retainer for connecting two panels of a heat shield assembly, the retainer comprising:
a central elongate panel having a length l and a width w, a top end, a bottom end and first and second long sides extending from the top end to the bottom end; and a first side panel extending along the first long side of the central elongate panel and a second side panel extending along the second long side of the central elongate panel, wherein reinforcement features are applied to a surface of the central elongate panel, and wherein the reinforcement features are beads stamped onto the surface of the retainer.

2 . The retainer of claim 1 , further comprising a tab extending from the top end.

3 . The retainer of claim 2 , further comprising a fastening hole formed in the tab.

4 . The retainer of claim 1 , further comprising a foot at the bottom end.

5 . The retainer of claim 4 , further comprising a locating hole in the foot.

6 . The retainer of claim 1 , the central elongate panel and the first and second side panels being formed from a single piece of sheet metal.

7 . The retainer of claim 1 , wherein the reinforcement features extend along the length of the retainer.

8 . The retainer of claim 1 , wherein the reinforcement means features are provided at discrete locations on the surface of the retainer.

9 . A heat shield assembly for a wheel assembly, comprising a plurality of arcuate heat shield panels arranged to be connected together to form a heat shield to be attached to the interior of a wheel, and the retainer as claimed in claim 1 , for attaching adjacent panels.

10 . The heat shield assembly as claimed in claim 9 , wherein one or more retainers is provided between each pair of adjacent panels.

11 . The heat shield assembly of claim 9 , wherein each panel comprises two heat shield panel layers arranged radially adjacent each other and wherein the retainer prevents relative movement of the two heat shield panel layers.

12 . A wheel assembly comprising a wheel rim having a radially inner surface and a radially outer surface, and the heat shield assembly as claimed in claim 10 , attached to and having the radially outer surface radially spaced from the radially inner surface of the wheel rim.

13 . The wheel assembly of claim 12 , further comprising a plurality of torque bars arranged around the radially inner surface of the heat shield, a torque bar positioned along the central elongate panel of each retainer of a plurality of retainers.

14 . The wheel assembly of claim 12 , being the wheel assembly is for a landing gear of an aircraft.
