嵌め込みフレーム構造及びそれを用いた筐体
Document Type and Number:
Japanese Patent JP5558633
Kind Code:
B2
Abstract:
To enhance the positioning accuracy between primary members and auxiliary members without need of latch parts such as rivets, an insertion frame structure includes: a pair of primary members (10) having L-shaped cross-sections and placed with the L shapes facing to each other symmetrically; and several auxiliary members (20) having angular U-shaped cross-sections between the primary members (10). The primary members (10) and the auxiliary members (20) are joined at latch portions. The latch portions of the primary members (10) have clearance-shaped latch holes (11a, 11b). The latch portions of the auxiliary members (20) have convex portions to be inserted into the latch holes (11a, 11b). Each latch hole (11a, 11b) has a clearance with a larger dimension than a plate thickness (t) of the auxiliary members (20), and continuously from the clearance, a clearance with a dimension smaller than the plate thickness (t) of the auxiliary members (20).
