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 and an inner middle block. The inner section includes an inner rail slidably disposed on the middle rail, and a removal operating assembly disposed on the inner rail. The removal operating assembly has a removal operating member, a removal connecting plate and a removal locking member pivotably mounted on the inner rail and having a removal guiding slot. The removal locking member has a locking portion and a protrusion. The removal operating member is operated to move the removal connecting plate and bring the protrusion to move along the removal guiding slot to result in pivoting of the removal locking member so as to disengage the locking portion from the inner middle block for permitting removal of the inner section from the middle section.

Abstract: A hinge includes a base frame unit and a rotating unit. The base frame unit includes a base seat having two rotating recesses and a transmitting recess, and two interfering plates respectively disposed in the rotating recesses. The rotating unit includes two rotating members respectively and rotatably disposed in the rotating recesses, and a bevel gear member disposed in the transmitting recess. Each rotating member frictionally interferes with the respective interfering plate, and has a bevel gear portion meshing with the bevel gear member. A torque generated as a result of rotation of one rotating member is transmitted through the bevel gear member to rotate the other rotating member relative to the base seat so as to make stable synchronous rotation of the rotating members.

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 base seat that includes a rack extending in a front-back direction; a moving platform that is movable on the base seat along the front-back direction; and a shaft unit that includes a rotating shaft rotatably extending through the moving platform in a left-right direction, a main gear member rotatably extending through the moving platform, co-movable with the moving platform, and meshed with the rack to constitute a rack and pinion system, and a first bevel gear piece fixedly sleeved on the rotating shaft, and meshed with the main gear member such that rotation of the rotating shaft results in collective linear front-back motion of the shaft unit and the moving platform relative to the base seat.

Abstract: A hinge assembly is provided for hingedly connecting a first frame to a second frame, and includes at least one hinge module which includes a first mounting base, a first connection member, a second connection member, and a transmission unit. The first and second connection members are coupled to the first and second frames, respectively, and are turnably mounted to the first mounting base respectively about first and second turning axes which are parallel to and offset from each other. The transmission unit is provided to permit the first and second connection members to turn in opposite rotational directions from each other whilst turning simultaneously.
