Abstract
A heat isolating linkage (5) that includes an elongate link having first and second end portions (10, 12) and a middle portion (14) extending therebetween. A bearing opening (16) is formed in the first end portion (10) and a bearing race (18) is disposed in the bearing opening (16). A rod end ball (20) is disposed in the bearing race (18). At least one aperture (30-36) is formed through the middle portion (14). The middle portion (14) may include a plurality of apertures (30-36) each in the form of a rectangle that forms a ladder pattern. Accordingly, the middle portion (14) has a cross sectional area (A2) that is smaller than the cross sectional area of at least one of the first and second end portions (A1, A3).
