摘要:
A hinge connection between first and second links, including a shaft; a threaded aperture formed within an end portion of the shaft; and a pair of bearings. The hinge connection may optionally include a spacer surrounding the shaft. In addition, there is also a bushing surrounding the end portion of the shaft. A threaded fastening member is inserted into the threaded aperture of the shaft. Upon insertion and tightening of the threaded fastening member, any axial gap between the first bearing and the bushing is eliminated. Also disclosed is a hinge connection with a split shaft, including two cantilever shafts, where a main axial portion of each cantilever shaft is seated within a bore of the first link; and a pair of bearings, where an inner portion of each of the cantilever shafts is rotatably seated within one of the bearings.

A casement window hinge protects against sash sag by providing a guide arm that substantially tills the space between the sash and the window frame when the window is closed. This space-filling guide arm may be produced with lightweight thermoplastic material whose pivoting connection to the sash arm may be strengthened through a wood screw providing an axis for the pivot that may be stabilized within the sash into which the screw is driven.

An anti-interference structure of relative slide assembly includes a relative slide member and a slide member. At least one guide member is disposed on the relative slide member. The guide member has a support section rising from a surface of the relative slide member. At least one guide slope is formed on one side of the support section. The slide member is relatively slidably connected with the relative slide member. At least one raised abutment section is disposed on the slide member and slidable with the slide member. The support section is positioned in the sliding path of the raised abutment section. During the sliding movement of the slide member along the relative slide member, the raised abutment section abuts against the support section to enlarge the gap between the slide member and the relative slide member so as to avoid interference therebetween due to deformation of the components.

A rotatable coupling mechanism includes an annular base member and a first annular member. A second annular member is mechanically coupled to the annular base member. A resilient member is disposed between the first annular member and the second annular member.

An adjustable friction hinge with a first hinge portion with two spaced apart first hinge knuckles and second hinge portion having a second hinge knuckle with rotatably fit together. A barrel bushing is non-rotatably positioned in the second hinge knuckle. A friction bushing is slidably and non-rotatably located in openings in the two first hinge knuckles. A threaded compression nut, and a non-threaded compression nut are located in the two spaced apart first hinge knuckles. A screw passes through the non-threaded compression nut, the spaced apart first hinge knuckles, the second hinge knuckle, the two friction bushings, and into the threaded compression nut. When the screw is tightened, the threaded and non-threaded compression nuts force the two frictional bushing into frictional contact with the barrel bushing to increase a force required to move the first hinge portion and the second hinge portion relative to each other.

A hinge includes a shaft sleeve, a shaft, and a spring. The shaft sleeve includes a shaft tube, and the shaft includes a fixing rod rotationally received in the shaft tube. The spring is received between the shaft and the shaft tube for guiding lubricant to lubricate the shaft and the shaft tube. The fixing rod is rotatably passed through the spring, and capable of rotating relative to the shaft tube.

A pivot assembly for securing a pair of mounting lugs and stabilizing a machine member has an axis member having a first end member and a second end member. An opening is formed in both the first and second end members. A pair of expansion sleeves is provided wherein one of the pair of expansion sleeves is positioned over each of the first end and second end members. A pair of locking devices is provided wherein one locking device is inserted into the opening formed in each of the first and second end members of the axis member. The locking devices engage the pair of expansion sleeves causing the expansion sleeves to expand to secure the axis member in a pair of mounting lugs. A chamber member is formed around a central area of the axis member. At least one lubricant chamber member is formed between the central area of the axis member and the chamber member. A pair of friction seal members is provided wherein one friction seal member is attached on each end of the axis member and to the chamber member to form an annular sealing around the axis member and the chamber member to prevent a lubricant in the lubricant chamber member from leaking.

A pivotal hinge has multiple washers, positioning spacers and an oil-retaining collar mounted around the washers and the positioning spacers filled with lubricating oil. The oil-retaining collar prevents the lubricating oil from flowing out of the pivotal hinge, prevents the components from wearing away, keeps the pivotal hinge rotating smoothly and has hooks formed separately on the two edges. The hooks hold the collar securely around the pivotal hinge.

A variable resistance hinge is mounted in a notebook computer having cover and a base and the hinge has a stationary leaf, a pivoting leaf and a pressing assembly. The stationary leaf is attached to the base and has a keyed shaft. The pivoting leaf is mounted pivotally on the shaft and is attached to the cover. The pressing assembly is mounted around the shaft, presses the pivoting leaf against the stationary leaf and has a pivoting ring and a stationary ring. The pivoting ring rotates around the shaft, is attached to the pivoting leaf and has at least one stepped detent. The stationary ring engages the shaft, abuts the pivoting ring and has at least one friction protrusion. Each friction protrusion corresponds a stepped detent and provides variable friction when opening the cover to enhance lifespan of the hinge and facilitate opening of the notebook.
