Abstract

A torque module for hinge device includes a holding support having two pivotal connection sections respectively having a pin extended therethrough, and two pairs of swing arms pivotally fitted on the pins to extend parallelly with each other and contact with two axially opposite sides of the pivotal connection sections with a gap (A) formed between them. Elastic elements are fitted on the pins to elastically press the pivotal connection sections toward at least one of the two pairs of swing arms for them to firmly and frictionally clamp to the two axially opposite sides of the pivotal connection sections and accordingly, provide a torque that can always hold the swing arms in place relative to the pivotal connection sections, no matter how the swing arms in each pair are pivotally turned relative to each other about the pivotal connection sections to any folded or extended angular position.

Dependent claims

A torque module for hinge device, comprising:

a holding support (1) having two pivotal connection sections (11), each of said two pivotal connection sections having a pin (14) pivotally extending therethrough;
two swing arm assemblies (2, 2a) pivotally connected to the two pins (14) and including a pair of primary swing arms (21) and a pair of secondary swing arms (22, 22a);
the primary swing arms (21) and the secondary swing arms (22, 22a) being extended in parallel and located adjacent to each other in a direction perpendicular to the pins (14);
the primary swing arms (21) respectively having a first clamping surface (213) in contact with one side of the pivotal connection sections (11), and the secondary swing arms (22, 22a) respectively having a second clamping surface (223) in contact with another axially opposite side of the pivotal connection sections (11);
and a gap (A) being formed between the primary swing arms (21) and the secondary swing arms (22, 22a) when the primary swing arms (21) and the secondary swing arms (22, 22a) are pressed against the two axially opposite sides of the pivotal connection sections (11);
and
at least one elastic element (5) fitted on each of the pins (14) to elastically press the pivotal connection sections (11) against at least one of the pair of primary swing arms (21) and the pair of secondary swing arms (22, 22a), such that the first clamping surfaces (213) of the primary swing arms (21) and the second clamping surfaces (223) of the secondary swing arms (22, 22a) are elastically pressed against the two axially opposite sides of the pivotal connection sections (11) to clamp the pivotal connection sections (11) therebetween, and a torque is provided to locate the two swing arm assemblies (2, 2a) in place relative to the holding support (1), no matter how the two primary swing arms (21) and the two secondary swing arms (22, 22a) are respectively turned or folded relative to each other about the pivotal connection sections (11), wherein the primary swing arms (21) are provided on respective one end with a pin hole (211) for fitting on around the pins (14), and on a respective one side facing toward the secondary swing arms (22, 22a) with a mating coupling section (214);
and the secondary swing arms (22, 22a) being provided on respective one end with a pin hole (221) for fitting on around the pins (14), and on respective one side facing toward the primary swing arms (21) with a coupling section (224) corresponding to the mating coupling section (214);
and the secondary swing arms (22, 22a) and the primary swing arms (21) being movable synchronously through engagement of the coupling sections (224) with the mating coupling sections (214).
