Abstract
A pair of embossments provided on either mounting arms of a cover pivotably attachable to a housing or, alternatively, provided on mounting surfaces of the housing, engage specifically defined recesses formed in the member on which the embossments are not formed. The embossments and recesses are all coaxially aligned with respect to an axis passing through a portion of the housing and about which the cover rotates between open and closed positions. The embossments are shaped such that positive engagement in the recess is assured when the cover is at predefined positions, such as the open and closed positions, thus inhibiting movement of the cover from the selected position. The present invention is particularly adaptable to small, portable telecommunications instruments, such as cellular phones having a flip cover, and effectively solves the problem of detent member breakage if the instrument is dropped or the need for costly spring mechanisms.
