Abstract: The present invention provides a foldable display support, wherein when a support arm is in a standing state, a limiting sheet is located in a limiting part of a screen support rack for blocking, so only the forward/backward tilted angle of a screen can be adjusted, thereby preventing being unstable and falling due to the gravity center being overly backward. When the support arm is folded to a horizontal state, the gravity center is lowered, and a protrusion of a first cam abuts a protrusion of a second cam, such that the second cam axially moves and pushes the limiting sheet to be released from the limiting part of the screen support rack, at this moment, the screen is enabled to be backwardly rotated and folded to a horizontal state for reducing the occupied space, thereby ensuring the folding process to be smooth and stable and preventing from falling.

Abstract: A dual swing hinge structure includes two fixed base frames each having a receiving groove and a pivot hole extending across the receiving groove, a first bracket, which has two coupling arms respectively inserted into the receiving grooves of the base frame and pivotally coupled to the pivot holes of the base frames with pivot pins and a mounting plate fastened to a first movable member, a second bracket, which has two coupling arms respectively pivotally coupled to the pivot pins that pivotally secure the first bracket to the base frames and a mounting plate fastened to a second movable member, and two first retaining members and two second retaining members respectively affixed to the coupling arms of the first bracket and the coupling arms of the second bracket and respectively coupled to the pivot pins for imparting a different torque force to the pivot pins such that the first bracket is immovable when the second bracket is biased relative to the base frames, and the second bracket is moved with the fir

Abstract: The present invention discloses a positioning device for hinge structure, comprising a fixed part, a rotatable part, a pivotal axle, at least an elastic part, a nut, and a cam member. The pivotal axle is passed through the first pivotal portion of the fixed part and the second pivotal portion of the rotatable part to render the rotatable part rotating relative to the fixed part and with respect to the pivotal axle. Consequently, through the rotation of the cam member, the contacts of the first and second contact faces with a pivoting portion is alternated and thus the distance between the contact faces and the pivotal portion is changed, rendering the nut pressing against or relaxing from at least one elastic part. The axial frictional force generated between the fixed part and the rotatable part is therefore changed so as to achieve positioning or rotation of the fixed part and the rotatable part.

Abstract: The present invention relates to a supporting structure capable of vertically elevating, comprises a pair of retracting devices, a base seat and a supporting device; by applying a force to the pair of retracting devices, the elbow joint section disposed at a pivotal connecting location between the top and the bottom rotation sheets is inwardly or outwardly moved, thus the top and the bottom rotation sheets correspondingly close or away from each other, so it can be ensured that the height of the supported objected is vertically adjusted without occupying too much space; and the present invention provides a function of vertically elevating, so problems that a base seat has to be pivotally connected to at the rear portion due to the forward/backward movement of the supported object has overcome and the appearance of the base seat can be styled to enhance the artistic sensation.

Abstract: The present invention is to provide an arresting device for hinge assembly structure, comprising a fixed part and a movable part assembled together and then connected with the pivot such that the movable part can be rotated with respect to the fixed part; an engagement assembly in which a rotation base disposed with an engagement portion at its outer side is securingly disposed at the outer side of the movable part for the insertion of the pivot, a slide base disposed with a retention portion at its inner side corresponding to the engagement portion is abuttingly connected onto the outer side of the rotation base, also for the insertion of the pivot, and moved integratedly with the rotation base, and a resilient part disposed at the hollow seat chamber between the two bases for the insertion of the pivot; consequently, when the outer side of the slide base is applied with an external force from a compression member, the slide base moves toward the rotation base and compress the resilient part, such that the r
