Abstract
A hinge has at least one hinge part which can be mounted in an opening in a thin wall such as a sheet-metal cabinet door, a head part, such as a flange or hinge leaf, which overlaps the rim of the opening of the thin wall on its (outer) side, and a body part which proceeds from the head part and can be pushed through the opening in the thin wall, and a holding part which is carried by the body part, supported on the other (rear) side of the thin wall, and is separate from the body part. The holding part is formed by holding elements which project in a flexible manner from the body part in the direction of its outer surface and whose free end has an inclined surface for supporting the body part on the rim or edge of the opening without play.
Claims14
A hinge in combination with a thin wall, the thin wall having an outer side, and inner side opposite the outer side, and an opening having a rim, comprising:
- a first hinge part mounted on the thin wall;
- a second hinge part swivelably connected to the first hinge part by a pivot pin;
- the first hinge part comprising a head part abutting the outer side of the thin wall;
- a body part protruding from the head part, the body part inserted through the opening, the body part including a guide channel formed by a plurality of side wall and a bottom wall, the guide channel positioned on the inner side of the thin wall;
- and
- a holding part which is carried by the body part;
- said holding part being formed by holding elements which project in a resilient manner from the body part in the direction of its outer surface and whose free end has:
- (1) a first smooth inclined surface which, when assembled, contacts the rim of the opening so as to support the body part on the rim of the opening without play, the first smooth inclined surface having an inclination angle being greater than 0° and less than 45° with respect to a direction of the first smooth inclined surface's sliding movement, and the holding elements being secured to the rim by a friction force generated at a support area between the rim and the first smooth inclined surface that hinders the holding element from being pushed outward out of the opening at a support position and supports the body part on the rim of the opening without play;
- and
- (2) a second smooth inclined surface which enables the holding part and the body part to be pushed through the opening to reach a support position, the two inclined surfaces being inclined with respect to a plane of the thin wall;
- wherein the holding elements are formed by two flat pieces lying next to one another with a flat surface of one flat piece of the two flat pieces touching a flat surface of the other flat piece of the two flat pieces, each flat piece having a rectangular opening, these two openings together forming a rectangular space which receives a spiral pressure spring by at least a portion of its diameter;
- and
- wherein an axis of the spring is arranged along a plane located between the two holding elements.
