A hinge having a pair of bathtub mounting blocks mounted to a bathtub surround adjacent a door jamb and a pair of door mounting blocks mounted to a bathtub door, with articulating linkage extending between the bathtub mounting blocks and the door mounting blocks. The articulating linkage has a pair of bathtub arms that pivotally couple at a first end to the bathtub mounting blocks through a first pivot rod and pivotally couple at a second end to a pair of door arms through a second pivot rod. Each door arm pivotally couples at an opposite end to one of the door mounting blocks through a third pivot rod. A spring mounted about the first pivot rod enables the bathtub arms and the bathtub door to rise. A method of door closure and opening for a walk-in bathtub is disclosed.

A piezoelectric energy harvester system for collecting kinetic energy is provided, wherein the kinetic energy is converted into electrical energy, and wherein at least a portion of the converted electrical energy is utilized to operate a load. The system comprises an energy input portion and an energy harvesting portion. The energy input portion includes an input member configured to be actionable by an outside force. The energy harvesting portion includes a capture member, a sprocket portion, and a piezoelectric energy harvester. The capture member is adapted for receiving mechanical input from the input member. The sprocket portion is disposed for movement with the capture member. The sprocket portion includes at least one radially disposed sprocket actuator configured for making contact with and exciting the piezoelectric energy harvester. The piezoelectric energy harvester is excited by the contact to produce the kinetic energy.

Disclosed are a hinge and a refrigeration equipment. The hinge includes a vertical hinge shaft, a first hinge base and a second hinge base. The first hinge base includes a first installation plate and a first sleeve rotatably connected to the hinge shaft to make the first sleeve rotate around the hinge shaft. A lower end of the first sleeve is provided with a first slope sloping downwards. The second hinge base below the first hinge base includes a second installation plate and a second sleeve fixed on the hinge shaft. An upper end of the second sleeve is provided with a second slope sloping upwards. The second slope abuts against and cooperates with the first slope for the first sleeve to move from a first position to a second position along a direction away from the second sleeve or from the second position to the first position along a direction close to the second sleeve while being rotated around the hinge shaft.

A display device includes: a display module; a first support part and a second support part disposed below the display module, the first and second support parts being arranged in a first direction; a hinge disposed between the first and second support parts below the display module to define biaxial rotation axes extending in a second direction intersecting the first direction; and a plurality of rotation parts coupled to the hinge to rotate about the biaxial rotation axes, the plurality of rotation parts being connected to the first and second support parts, respectively. Each of the rotation parts includes first and second parts that move relative to each other via a lost motion connection upon rotation of the rotation parts.

A refrigerator door hinge pivotably supports first and second doors of a refrigerator for independent movement. The refrigerator door hinge includes a bracket, and first and second arms extending outwards and away from the bracket. The first and second arms are arranged such that a gap is formed therebetween. A first pivot pin is provided for pivotably supporting the first door and is disposed adjacent the first arm. A second pivot pin is provided for pivotably supporting the second door and is disposed adjacent the second arm. An adjustment screw is positioned within a first inner channel of the first pivot pin and is configured to engage a shaft of the first door and to translate within the first inner channel so as to translate the shaft to vertically adjust a height of the first door.

A hinge device includes a fixed element with a plate that can be anchored to a stationary supporting structure, and a movable element with a hinge body that can be anchored to a closing element. Adjustment elements for the position of the hinge body and the plate include a pair of opposite longitudinal projections integrally joined to a pin that can be inserted into a slot defined in the plate. A pair of adjustment grub screws at the slot promotes the joined rotation of the longitudinal projections and the pin. The hinge body further includes a seat, for the mutual movement of the pin and of the hinge body, with a damping system interacting by friction with the pin to differentially dampen the rotation of the pin and the hinge body. The hinge device may be fixed to the closing element with a pair of clamping elements.

A door hinge has a first leaf assembly, a second leaf assembly, and a link assembly connected to the leaf assemblies for pivoting of the second assembly on the first assembly. An adjuster in the first leaf assembly can displace the link assembly relative to the first leaf assembly and thereby adjust a position of the door in the frame. The adjuster has an adjusting element projecting from the first leaf assembly in the closed position. The second leaf assembly is formed with a recess in which the projecting adjuster engages in the closed position.

A hinge has first and second leaf assemblies pivoted on each other and a link assembly interconnecting the first and second leaf assemblies. At least one of the first and second leaf assemblies has upper and lower mounts forming a cavity in which a respective end of the link assembly is pivoted, and at least one of the mounts of the one leaf assembly is formed with a recess opening into the cavity. According to the invention a body of foaming fire-protection material is provided in the recess so that when heated the body expands and fills the cavity with fire-protective foam.
