Abstract: A multi-linkage hinge includes a base bar, two friction bars, two synchronous rotation bars and two torsion plates. The base bar extends longitudinally to have two connecting ends and two middle pivot portions . Each friction bar has two link ends respectively coupled to the connecting end of the base bar and a middle portion of the respective torsion plate. The synchronous rotation bars are interposed between the friction bars, and each has two pivot ends respectively coupled to the middle pivot portion of the base bar and a driven end of the respective torsion plate. The torsion plates are turnable synchronously relative to the base bar between unfolded and folded positions. In the unfolded position, a bending space is formed between the torsion plates for receiving a bending portion of the display sheet.

Abstract: An angularly positionable flexible display device includes a flexible display, a first substrate, a second substrate, and a positionable hinge mechanism which is disposed in a mounting space defined between the first and second substrates. In response to application of a manual force upon at least one of the first and second substrates, the first substrate is angularly displaceable relative to the second substrate through the positionable hinge mechanism to permit the flexible display to be bent with the angular displacement of the first and second substrates. Once the manual force is release, the first substrate is angularly positioned relative to the second substrate through frictional force provided by the positionable hinge mechanism.

Abstract: A sliding rail device includes a first rail, a second rail and two supporting units. The first rail includes a first base wall, and two first side walls cooperating with the first base wall to define a first passage. Each of the first side walls has an engaging slot. The second rail engages the first passage, is movable relative to the first rail, and includes a second base wall and two second side walls. The two supporting units respectively and movably engage the engaging slots of the first side walls, and abut respectively and slidably against the second side walls. During movement of the second rail relative to the first rail, the supporting units are driven to respectively move along the engaging slots of the first side walls, and to move toward each other to tighten abutment of the supporting units against the second side walls.

Abstract: A pipe coupler with locking structure includes male and female parts connected end-to-end. The male part includes a male coupler body provided with at least one groove, a spring fitted on the male coupler body with an end fixed thereto, and a sleeve enclosing the male coupler body and the spring therein with another end of the spring fixed thereto. A retaining member is connected at an end to the sleeve with a protruded element provided on a free end thereof to movably engage with to or disengage from the groove on the male coupler body. The female part includes a female coupler body externally provided with at least one slantly extended guiding groove. When the sleeve is rotated, the protruded element is moved in the guiding groove to a closed tail end thereof and the spring is stretched forward to elastically pull the male and female coupler bodies together.

Abstract: A lock device structure includes an assembly of a case body and an actuator body, a linking member and a slide body mounted on the case body. The actuator body has two arm sections and a notch section positioned between the two arm sections. An operation member and an elastic member are disposed in the notch section. The elastic member serves to make the operation member reciprocally move in an axial direction of the actuator body. The linking member has a first end pivotally connected with the actuator body (or the operation member) and a second end connected with the slide body. When an operator pulls (and pushes) the operation member to move, the actuator body is permitted to move from a closed position to an open position to drive the linking member and the slide body to move.

Abstract: A hinge includes a seat, a shaft, a swivel bracket and at least one limiting bar. The seat includes two support portions. An accommodation area is defined between the two support portions. The two support portions are respectively provided with a shaft hole. The two shaft holes are arranged coaxially and connected to the accommodation area. The shaft includes a coupling section and two pivoting sections. The coupling section is located between the two pivoting sections. The two pivoting sections are respectively provided in one of the two shaft holes in a rotatable manner, and the coupling section is in the accommodation area. The swivel bracket includes a mounting plate, a sleeve piece and at least one extension portion. The mounting plate includes an inner surface, an outer surface, and a bottom edge. The sleeve piece extends from the bottom edge of the mounting plate and is wound at a side corresponding to the inner surface. The sleeve piece is configured to be sleeved over and fixed to the coupling section, such that swivel bracket is fixed to the shaft and rotatable with respect to the seat to move the inner surface to face the accommodation area. The extension portion is adjacent to lateral edges of the sleeve piece and extends from the bottom edge and is bent towards the side corresponding to the inner surface. The limiting bar is disposed on one of the two support portions and is in the accommodation area. The limiting bar is in a rotational path of the extension portion. When the swivel bracket is flipped outward with respect to the seat, the extension portion moves towards the limiting bar.

Abstract: A three-section slide rail device includes an outer section, a middle section and an inner section. The middle section includes a middle rail slidably disposed on the outer section, a ball sliding plate slidably disposed on the middle rail, and a leaf spring at one end of the middle rail. The ball sliding plate has a plate body, a synchronizing block and a positioning hole formed on the plate body. The inner section includes an inner rail and a synchronizing actuating member pivotably mounted to the inner rail. The synchronizing actuating member is in an abutting engagement with the synchronizing block during an extended movement of the inner section relative to the middle section to make synchronizing movement of the ball sliding plate with the inner section until the positioning hole of the ball sliding plate is engaged with the leaf spring.

Abstract: A hinge includes a stationary seat and two rotating units. Each rotating unit includes a linkage module that has an extension body that has a arcuate slide rail, a rotating bracket module that is rotatable and that has a fixing pin, and a sliding module that includes a connecting frame, a positioning pin, and a linkage member. The connecting frame has a curved groove that engages the arcuate slide rail such that movement of the rotating units between an opened and a closed state results in movement between the arcuate slide rail and the curved groove. The linkage member has a through hole, and an elongated slot which the fixing pin passes through to connect the rotating bracket module such that movement of the rotating units between the opened and closed states results in movement between the fixing pin and the elongated slot.

Abstract: A displaceable rotating shaft structure and a foldable device having the rotating shaft structure are disclosed. The displaceable rotating shaft structure comprises a support, a rotating shaft, a connecting rod assembly, a guide assembly, and a torsion assembly. The support has a supporting portion. The connecting rod assembly has a first outer end that is rotatably connected to the linking section of the rotating shaft and a second outer end that is pivotally connected to the supporting portion. The guide assembly has a guide rod. The guide rod is configured to displace relative to the supporting portion. When the rotating shaft is rotated, the rotating shaft drives the connecting rod assembly to adjust the angle and the total length of a joint of connecting rods of the connecting rod assembly, a distance between the rotating shaft and the support is changed through the guide assembly.
