Abstract: A hinge device for armrails of a playpen.

Abstract: The device serves to delimit a set-up angle between two planar components which are connected with one another by means of a hinge (1, 2), for example between the picture cover (3) of a picture frame and a supporting base (4). The device is characterized by a connecting web (8) which at one end is provided with one half of a hinge base joint (54) and at the other end is configured as a T-shaped member (89). The other half of the hinge base joint can be fastened to one of the two planar components--the picture cover (3).

The width of the cutout (23) in the region facing the hinge (1, 2) is greater than the width of the transverse portion (80) of the T-shaped member (89). A step (30) is provided at the transition from the narrower to the broader region.

Abstract: A 180.degree. concealed hinge includes two pivots which are advantageously arranged to provide a deterministic opening sequence. The hinge comprises a frame leaf member and a door leaf member which are pivotally connected to a mounting leaf member. In one embodiment of the invention, the deterministic opening sequence is obtained by employing a loose fit pivot and a friction fit pivot. The deterministic opening sequence is such that rotation occurs first about the loose fit pivot from a closed position to an approximately 90.degree. open position when an opening rotational force is applied to the door leaf member. Upon reaching the 90.degree. open position, further rotation about the loose fit pivot is prevented by a unique stop arrangement. Then, rotation can occur about the friction fit pivot for an additional 90.degree.. Further rotation about the friction fit pivot is prevented by also employing another unique stop arrangement.
