Patent ID: 8240941

Claim:
A flexure for tiltably mounting an object to a support surface, comprising: a block of elastic material having mounting surfaces at opposing longitudinal ends thereof which extend transverse to a longitudinal axis of the block, the block having first and second cylindrical openings therein with a neck therebetween, each of said openings having a length dimension extending completely through said block in an axial direction transverse to the longitudinal axis, first and second slits in the block, each extending along a sidewall surface of said block and to a respective one of said openings and extending completely through said block in an axial direction transverse to the longitudinal axis, wherein said first slit at an end forms an entrance to said first cylindrical opening and said second slit at an end forms an entrance to said second cylindrical opening, said neck having a shortest dimension extending directly between said openings at the narrowest region of the neck and a long dimension which is transverse to the shortest dimension, each of said first and second cylindrical openings having a cross-sectional shape transverse to said axial direction which is elliptical with an eccentricity of greater than 0.69 and less than 0.96 and which is elongated in a direction which is parallel to said long dimension of the neck, wherein when said mounting surfaces are displaced relative to each other, tilting can occur around said neck while voids formed by the slits are utilized for accommodating the tilting movement.
