Abstract: A control assembly for a hinge connection is mounted within a lap top, palm top or handy personal computer, or the like. The assembly comprises an elongated pivot member, a brake member disposed around the pivot member, a small-scaled holding member fixedly secured to the display unit or a computer body, and adjusting means for clamping the holding member against the brake member. The holding and brake members have a barrel portion for setting the pivot member and two leaf portions, respectively. Furthermore, the inner surface of the holding member corresponds to the outer surface of the brake member. Thus, the brake member is rotatable about the pivot member together with the holding member.
