Hinged case providing sectional cover with anti-pinch interleaving through |
摘要 |
Interleaving troughs (28-30) are securely fixed to a front cover (12) and a back cover (14) of a hinged apparatus (10). The first and second troughs (28-30) are generally semicircular in shape and are dimensioned to slidably cooperate with each other. A gap (34) is formed between the second trough (30) and the back cover (14) to receive the first trough (28) when the apparatus (10) is in a fully opened position. When the apparatus (10) is closed, first and second troughs (28-30) form a generally cylindrical container (36) for holding a wire spiral (26) of a book (20). When the apparatus (10) is closed, a void (38) of less than 3/16 inch is formed between the first and second troughs (28-30). The void (38) meets the ASTM standards for toy safety with regard to a pinching hazard.
