Please substitute the new Abstract submitted herewith for the original Abstract: A hinge system of a hood of a vehicle has a hinge which is arranged between the hood and a mating element of the vehicle. The hinge is designed both for opening the hood and for raising the hood when the latter is in the closed state, and includes a lifting-piston actuator for initiating a raising movement of the hood. The lifting-piston actuator has a piston element which can be connected to the hinge and/or the hood in a form-fitting manner in order to limit freedom of movement of the hood.

A unique anti-warping anti-sagging interlocking gate comprises: multiple triple-U-shaped-clamp bracket systems having front and rear plates and bracket tube nuts, multiple anti-warping anti-sagging interlocking-tube-nut hinge systems having crisscross 90-degree hinge tube nuts, multiple struts, a truss having cable ends and a cable clamp, and a truss-cable-clamp-hiding tunnel system. The front and rear plates and bracket tube nuts are for uniquely securing the triple-U-shaped-clamp bracket systems to the struts to prevent the interlocking gate from warping and sagging. The crisscross 90-degree hinge tube nuts are for uniquely interlocking the hinge systems to a fence post in two 90-degree interlocking directions and in five different crisscross interlocking elevations. The truss-cable-clamp-hiding tunnel system is for uniquely hiding the cable ends and a cable clamp inside one of the struts and under one of the triple-U-shaped-clamp bracket systems.

A hinge is provided, which comprises: at least one hinge pin defining a hinge axis in a first dimension; a hinge leaf; a housing comprising at least one recess for receiving a portion of the hinge leaf; and at least one user adjustable fastener arranged to enable user adjustment of the positioning of the hinge leaf within the at least one recess in a second dimension, wherein the second dimension is orthogonal to the first dimension.

An electrical generation system for a door positioned in a doorway includes a hinge arranged to support the door for rotational movement with respect to the doorway between a closed position and an open position, and a cam that is one of coupled to the door for movement with the door, and fixed with respect to the doorway. A piezo-electric generator is the other of coupled to the door for movement with the door, and fixed with respect to the doorway. The piezo-electric generator and the cam cooperate such that rotation of the cam with respect to the piezo-electric generator is operable to produce an electrical current in response to rotation of the door, and wherein the electrical current has a frequency that is greater than the number of revolutions made by the cam with respect to the piezo-electric generator.

A hidden, corner hinge assembly for a display case includes: (a) a fixed, inner rail with an interior space with an opening, (b) a movable, door rail with a semi-enclosed, interior space with a opening that is adapted to allow the adjoining fixed, inner rail to pass into and out of this opening when the display case's door moves between closed and open positions, (c) inner rail posts mounted within the semi-enclosed, interior spaces, (d) a first and a second link, each with an end that rotatably attaches to a rail post in each of the semi-enclosed, interior spaces, and (e) wherein the locations of the post mountings and the configurations and lengths of the link are set so as to allow the display case's door to open by moving inward and away from the vertical edge where the hinge assembly is being used.

The disclosure relates to a cupboard or household appliance, particularly a wall-mounted cupboard, comprising a carcass on which a door can be pivoted from a closed position into an open position by means of a pivoting device, at least one holder for storing objects being attached to an inner side of the door facing the carcass, the door being lowerable down a guiding device, in an open range of the door. The invention further relates to a method for opening and closing a cupboard or a household appliance.

A uniform distribution support structure of rotary shaft link assembly includes a rotary shaft assembly and a support assembly. The rotary shaft assembly has multiple connection members. Each connection member is formed with a hollow section and a perforation. A guide face is disposed in each hollow section. A spacer shaft rod is disposed between each two adjacent connection members. Each spacer shaft rod is formed with a through hole. A guide arched face is disposed in each through hole. The support assembly has a support member and a lateral support member passing through the through holes and the hollow sections. Multiple opposite guide arched faces are disposed on the support member. Multiple opposite guide faces are disposed on the lateral support member. The guide faces and the guide arched faces respectively abut against the opposite guide faces and the opposite guide arched faces.
