Combination of holder frame and rectangular plate

摘要

The holder frame (2) is fixed to the sides of the rectangular plate. The holder frame has a leg part (2a). It has a support part (2b) fixed to the rear surface of the plate in contact with it, and an edge part (2c) holding the periphery of the plate. The support part has a release part (2e) enabling the periphery of the plate to be gently held on a base part inside the edge part. One end of the leg part running at right angles to the rear surface of the plate, and one end of the support part extending along the rear surface of the plate to its centre are joined in one piece. A retainer claw (2h) on a top part extends along the surface of the plate and hooks onto the periphery on one side of the periphery of the plate.
