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; a first U-shaped fold joining the central elongate panel first long side to the first side panel, and a second U-shaped fold joining the second long side to the second side 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; 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; a first U-shaped fold extending perpendicular to the central elongate panel and joining the central elongate panel first long side to the first side panel; and a second U-shaped fold extending perpendicular to the central elongate panel and joining the second long side to the second side panel.

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 panel and the first and second side panels and the first and second U-shaped folds being formed from a single piece of sheet metal.

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

8 . The heat shield assembly as claimed in claim 7 , wherein one or more retainers is provided between each pair of adjacent panels.

9 . The heat shield assembly of claim 7 , wherein each panel comprises two heat shield panel layers arranged radially adjacent each other and wherein the retainer prevents relative movement of the layers.

10 . 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 7 attached to and having a radially outer surface and a radially inner surface, the radially outer surface of the heat shield assembly radially spaced from the radially inner surface of the wheel rim.

11 . The wheel assembly of claim 10 , 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.

12 . The wheel assembly of claim 10 being the wheel assembly for a landing gear of an aircraft.
