Abstract: For refrigeration units such as walk-in coolers and freezers, a shell, door frame and door panel assembly adapted to enclosed insulative panel constructions wherein the shell confines a selected standard and/or oversize door frame. The door frames are of composite plastic and steel construction including lightweight external plastic hardtracks forming top, sides and screed bottom, the purposes of the external construction being to confine frame elements which are formed of steel, such that by virtue of the separation of elements forming jamb frames and header frames, applied insulation to the overall assembly is rendered most effective. The standard and oversize door panel assemblies are adapted to encompass a precut retainer by means of inside and outside panels, the latter of which contains backup plates for hinges and for door closers and the like.

Locating members formed in the passages are used to locate and maintain the outer panel in a fixed relationship with respect to the inner supporting portion when they are assembled and bonded to one another.

Abstract: The present invention provides a connection structure which can freely adjust a connection strength between each stile and rail without increasing the kinds of stiles and rails arranging a door. A door 1A is arranged by engaging connection convex parts 21A and 31A of an upper rail 20 and a lower rail 30 in a connection concave part of a stile 10. In this case, the strength of the connection part of the stile and rail is set by adjusting an engagement dimension of the connection convex parts 21A and 31A in the connection concave part 12A. When the doors of different connection strength are arranged, only adjusting the engagement dimensions is required without the need to manufacture and assemble stiles and rails of different shapes and so on for each strength; therefore the manufacturing cost is reduced with the kinds of stiles and rails required being reduced and each kind of door with different connection strength can be easily arranged.
