Abstract

A thermal insulating structure includes: at least two first multilayer vacuum insulators that adjoin each other and that cover a to-be-insulated surface; a retainer that is fixed to the to-be-insulated surface and that protrudes from a boundary between the first multilayer vacuum insulators; a second multilayer vacuum insulator that extends along the boundary and that covers the boundary, the second multilayer vacuum insulator including a through-hole formed therein, in which the retainer is inserted; and a keep plate that is fixed to the retainer and that holds the second multilayer vacuum insulator and the first multilayer vacuum insulators.

First claim

The invention claimed is:

1. A thermal insulating structure comprising:
at least two first multilayer vacuum insulators that adjoin each other and that cover a to-be-insulated surface;
a retainer that is fixed to the to-be-insulated surface and that protrudes from a boundary between the first multilayer vacuum insulators;
a second multilayer vacuum insulator that extends along the boundary and that covers the boundary, the second multilayer vacuum insulator including a through-hole formed therein, in which the retainer is inserted; and
a keep plate that is fixed to the retainer and that holds the second multilayer vacuum insulator and the first multilayer vacuum insulators.

2. The thermal insulating structure according to claim 1 , wherein
the first multilayer vacuum insulators adjoin each other such that no gap is formed therebetween.

3. The thermal insulating structure according to claim 1 , wherein
each of the first multilayer vacuum insulators is joined to the to-be-insulated surface around the retainer by a pair of hook-and-loop fasteners.

4. The thermal insulating structure according to claim 3 , wherein
the pair of hook-and-loop fasteners is provided such that the pair of hook-and-loop fasteners overlaps the keep plate.

5. The thermal insulating structure according to claim 1 , wherein
the retainer is made of glass fiber reinforced plastic.

6. The thermal insulating structure according to claim 1 , comprising a plurality of the retainers, wherein
a plurality of the through-holes are formed in the second multilayer vacuum insulator.

7. The thermal insulating structure according to claim 6 , comprising a plurality of the second multilayer vacuum insulators, wherein
each of the plurality of the second multilayer vacuum insulators extends between two adjoining retainers of the plurality of the retainers.

8. The thermal insulating structure according to claim 1 , wherein
at least three of the first multilayer vacuum insulators are arranged in a particular direction,
the retainer is provided on each of boundaries between the adjoining first multilayer vacuum insulators,
the thermal insulating structure comprises a plurality of the keep plates, and

each of the plurality of the keep plates is a bar-shaped member whose both end portions are engaged with the respective retainers that are positioned at both sides of a corresponding one of the first multilayer vacuum insulators.
