Floating hinge

A floating hinge is a hinge that, while able to behave as a normal hinge, enables one of the objects to move away from the other - hence float. In effect the hinge allows for two parallel axes of rotation, one for each object joined by the hinge, and each axis can be moved relative to the position of the other.[1]

Book scanner with floating hinge.

Floating hinges are used in flatbed scanners designed to scan thick objects such as books. A sheet of paper is placed on the glass, and the cover is lowered over it; the glass, the paper, and the sheet are very close together. If a thick book is placed on the glass an ordinary hinge would leave the cover at an angle to the glass. A floating hinge raises the hinged edge of the cover to the level of the book, so that the cover remains parallel to the glass, but raised above it.[2]

Floating hinges are also used in two-plate electric cooking grills, as they allow for even heating of both sides of a thick piece of food without crushing it.[3]

Concealed hinge jig

A concealed hinge drilling jig is a type of support jig, designed for drilling 3 cm holes to fit concealed hinges into modern wardrobe doors. As many of the complementary tools used in woodworking, it uses an electric hand-drill for its operation, making a Forstner bit to turn.For most concealed hinges to work properly, a pit hole must be created on the door at the point where it faces the static part of the hinge which is screwed to the inside wall of the wardrob .To create the pit hole, the jig must be fixed in place by means of the provided clamp, spin the Forstner bit by applying an electric hand-drill to its axle. The hole is drilled by pressing the hand-drill until a satisfactory pit hole is created.The purpose of the drilling jig is to hold a Forstner bit in place, at a 90º angle while drilling 3 cm pit hole. The angle of the tool is critical for the performance of concealed hinges, the jig allows maintaining the 90º angle over a number of drilling sessions.

George Foreman Grill

The George Foreman Lean Mean Fat-Reducing Grilling Machine, commonly known as the George Foreman Grill, is a portable electrically heated grill manufactured by Spectrum Brands. It is promoted by former boxing champion George Foreman. Since its introduction in 1994, over 100 million George Foreman grills have been sold worldwide.


A hinge is a mechanical bearing that connects two solid objects, typically allowing only a limited angle of rotation between them. Two objects connected by an ideal hinge rotate relative to each other about a fixed axis of rotation: all other translations or rotations being prevented, and thus a hinge has one degree of freedom. Hinges may be made of flexible material or of moving components. In biology, many joints function as hinges like the elbow joint.
