A panel intended for use as a vacuum enclosure, comprising a pair of spaced sheets defining between them opposite walls of the enclosure, and a spacer assembly located between the sheets and adapted to maintain the sheets at the desired spacing, said spacer assembly comprising a pair of bearing pads positioned on the inside surfaces of the sheets at mutually opposite locations, a spacer element received between the bearing pads which spacer element is formed with substantially spherical bearing surfaces cooperating with the bearing pads, and spring means incorporated within the spacer assembly adapted to allow a limited degree of relative movement of the sheets in a direction substantially at right angles to the plane of the sheets.

DETAILED DESCRIPTION I claim: 1.
A panel intended for use as a vacuum enclosure, comprising a pair of spaced sheets defining between them opposite walls of said enclosure, a plurality of spacer assemblies located between said sheets and adapted to maintain said sheets at the desired spacing, each of said spacer assemblies comprising a pair of bearing elements positioned on the inside surfaces of said sheets at mutually opposite locations, a spacer element received between said bearing elements which spacer element is formed with substantially spherical bearing surfaces cooperating with said bearing elements, and spring means incorporated within each said spacer assembly adapted to allow a limited degree of relative movement of said sheets in a direction substantially at right angles to the plane of said sheets.
2.
A panel as claimed in claim 1, wherein said spherical bearing surfaces have the same geometrical centre.
3.
A panel as claimed in claim 1, wherein said spacer element comprising a spacer pin having enlarged end portions connected by a shank portion, and said spherical bearing surfaces are formed on the end faces of said enlarged end portions.
4.
A panel as claimed in claim 3, wherein at least one of said bearing elements is formed with a recess receiving the respective end portion of said spacer pin.
5.
A panel as claimed in claim 4, wherein said spring means comprises a disc spring positioned between the base of said recess and the spherical bearing face of the respective end portion of said spacer pin.
6.
A panel as claimed in claim 5, wherein both of said bearing elements are formed with the recesses receiving the respective end portions of said spacer pin, and said elements are deformed at the outer edges of said recesses around the enlarged ends of said spacer pin to form a unitary assembly.
7.
A panel as claimed in claim 1, wherein said bearing elements and said spring means are formed by an annular resilient member surrounding at least one end of said spacer pin and in engagement with the face of one of said sheets
