A method for making an electric hinge comprising providing first and second hinge plates, each hinge plate having at least one knuckle and forming in each hinge plate an open slot extending from an edge distal from the knuckle and terminating at a mid-portion of the hinge plate to the knuckle. The open slot depth is less than the thickness of the hinge plate. The method includes drilling a hole from the terminus of each open slot to the knuckle of the hinge plate and passing a wire through the hole from the terminus of the open slot to the knuckle in the first hinge plate and from the knuckle of the second hinge plate to the corresponding terminus of the second hinge plate. The method includes mating the first and second hinge plates by inserting a hinge pin through the knuckle of each hinge plates to form the electric hinge.

The present invention relates to the field of hinges and carriage mechanisms, such as a hinge and carriage mechanism adapted to hang a door, gate, panel, window or the like. The present invention is suitable for use with a means of providing height adjustment for a door and can reduce undesirable tampering and improve the security of the hinges and door assemblies by controlling the orientation of specific part of a hinge to limit access to the fastener.

A pivot structure assembly including a fixed cover and a hinge module is provided. The hinge module includes a torque element, a first shaft, a second shaft, a first bracket and a second bracket. The torque element is fixed on the fixed cover and has a first and a second axle sleeves, parallely disposed at two opposite sides of the torque element. The first shaft is disposed through the first axle sleeve, and the second shaft is disposed through the second axle sleeve. The first bracket is pivotally disposed on the torque element through the first shaft, and the second bracket pivotally disposed on the torque element through the second shaft. When the first and second brackets rotate relatively to the torque element, the first and second axle sleeves respectively provide different friction forces to the first and second shafts. In addition, an electronic device is also mentioned.

A corner fitting for a door element to be disposed on a center of rotation or an axis, including first and second fitting elements, which, at least sectionwise, each include a locating portion for the abutment against the door element, and are interconnectable while restraining the door element in a restraining area. The fitting elements delimit the restraining area, including at least one attaching unit for reliably clamping the door element between the fitting elements. The attaching unit includes first attaching means, disposed at the first fitting element and/or at the second fitting element, and second attaching means, disposed at the second fitting element and/or at the first fitting element. The attaching means are non-positively and/or positively interconnected. The first attaching means includes an engagement area, into which the second attaching means acts, wherein the engagement area extends at least partially into the restraining area via the locating.

The invention relates to a furniture hinge with a fastening portion and a hinge part connected thereto via a multi-axis articulated connection, wherein a spring preloads the hinge part directly or indirectly, at least in a subregion of the adjustment path of the hinge part, with respect to the fastening portion, and wherein the spring is mounted or can be mounted under tension between two spring bearings. In order, in such a furniture hinge, to achieve improved movement control and to make the required manual force for hinge opening or closing more even, provision is made according to the invention for the spring (76) to be adjusted in the region of its two spring bearings (74, 84.4) during the adjustment of the hinge part (20) from the opening into the closing position and/or during the adjustment from the closing into the opening position.

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 mortise jig assembly includes a block that is longitudinally elongated. The block has plurality of mortises therein and the block is clamped to a face of a door such that selected ones the mortises is aligned with an edge of the door. A jig panel is provided and the jig panel is positionable against the edge of the door to engage respective ones of the mortises thereby retaining the jig panel at a selected location on the edge of the door. The jig panel has a guide hole therein thereby facilitating the guide hole to be aligned with a preferred location to cut a hinge recess in the edge of the door. A pair of bolts is each extendable through the jig panel and the block for attaching the jig panel to the block.
