Control assembly for a hinge connection

Claim 2

A control assembly for a hinge connection between a display unit and a computer body, said assembly comprising: a pivot member mounted to the computer body or the display unit; a brake member made of hard plastic or plastics with minimum variation in wall thickness, which has a barrel portion disposed around the pivot member and two leaf portions with a space therebetween, whereby it introduces no new internal stresses; a holding member made of steel and connected to the display unit or the computer body, which has a barrel portion and two leaf portions corresponding substantially to the outer surface of the brake member, whereby said brake member is protected against distortions when compressed hard and is rotatable about the pivot member together with said holding member; and adjusting means for clamping the holding member against the brake member so that the barrel portion of the brake member compresses radially into frictional contact with the pivot member.

Claim 3

An assembly as set forth in claim 1, in which the adjusting means includes a screw put in slots made in the two leaf portions of the holding and barrel members.

Claim 4

An assembly as set forth in claim 1, in which the brake member is made of wear-resistant engineering plastic or plastics and the holding member is made of spring steel.

Claim 5

An assembly as set forth in claim 1, in which the lower leaf portion extends along a tangent line of the circular barrel portion, and the upper leaf portion extends parallel to the lower leaf portion along a desired distance.

Claim 6

An assembly for controlling the rotation of a display unit of a personal computer, said assembly comprising: an elongated pivot member mounted to the computer body or the display unit; a brake member made of engineering plastic or plastics with minimum variation in wall thickness, which has a barrel portion disposed around the pivot member and two leaf portions with a space therebetween, whereby it introduces no new internal stresses; a holding member made of spring steel and connected to the display unit or the computer body, which has a barrel portion and two leaf portions, including the lower leaf portion extending along a tangent line of the barrel portion and an upper leaf portion extending parallel to the lower leaf portion with a desired distance, the inner surface of the holding member corresponding to the outer surface of the brake member, said brake member being rotatable about the pivot member together with said holding member; and a screw put in slots made in the two leaf portions of the holding member and the brake member, for screwing up or clamping the holding member against the brake so that the holding member compresses the brake radially into friction contact with the pivot member.

Claim 7

An assembly for controlling the rotation of a display unit of a personal computer, said assembly comprising: an elongated pivot member mounted to the computer body or the display unit; a brake member made of engineering plastic or plastics with minimum variation in wall thickness, which has a barrel portion disposed around the pivot member and two leaf portions with a space therebetween, whereby it introduces no new internal stresses; a holding member made of spring steel and connected to the display unit or the computer body, which has a barrel portion and two leaf portions, including the lower leaf portion extending along a tangent line of the barrel portion and an upper leaf portion extending parallel to the lower leaf portion with a desired distance, the inner surface of the holding member corresponding to the outer surface of the brake member, said brake member being rotatable about the pivot member together with said holding member; and a screw put in slots made in the two leaf portions of the holding member and the brake member, for screwing up or clamping the holding member against the brake so that the holding member compresses the brake radially into friction contact with the pivot member.
