ABSTRACT:
CROSS-REFERENCE TO RELATED APPLICATIONS
The present application claims priority under 35 U.S.C. § 119 of German Patent Application No. 299 14 746.0, filed on Aug. 24, 1999, the disclosure of which is expressly incorporated by reference herein in its entirety.
BACKGROUND OF THE INVENTION
1. Field of the Invention
The invention concerns a pivoting hinge joint with a stationary hinge part and a pivoting hinge part which are joined to one another by a pin.
2. Discussion of Background Information
Such a pivoting hinge joint may serve as a device for e.g., holding a lid in a closed and/or locked position or in an opened position.
In the German disclosure document No. 2232379, a hinged lid with a self adhering closed and open position is described, where the lid is guided by a tappet which is guided in a groove with a right-angled bend under a force exerted by a tension spring.
In the German patent document No. DE 4240 790, a hinge for an upward pivoting hood of a motor vehicle is described which comprises a coupling rod with two specially formed guiding bars, a tension spring and a control lever for the coupling rods which can be folded into a guiding member and locked into this.
SUMMARY OF THE INVENTION
The invention provides for a pivoting hinge joint of a design which is simple to manufacture and permits easy handling with reference to its two stop-end positions, i.e., closed, open.
The invention provides a pivoting hinge joint with two end stop positions, characterised by a pivot arm and a stationary guiding piece, a pivot axis of the pivot arm, which is joined to the guiding piece and a guided member which can be guided in a guideway of the pivot arm and in a guideway of the guiding piece. The guideway of the guiding piece is not straight and is fitted with a turning point. At least one spring, by which the guided member is held in either of two stop positions, and that the pivoting motion of the pivoting arm for the path of the guided member from the stop-end position to the turning point, takes place against the force of the spring, and that from turning point the pivot arm can be pressed by the force of the spring into the other stop-end position.
The arrangement may also be characterised by the fact that the pivoting motion of the pivot arm from a stop-end position up to the turning point takes place against the increasing force of the spring.
The arrangement may be characterised by the fact that the spring is at least a torsion spring, through the ends of which pressure is applied to the guided member and the pivot arm.
The arrangement may further be characterised by the fact that the pivot arm is fitted with a retaining axis for holding the torsion spring.
According to one aspect of the invention, there is provided a pivoting hinge joint having two end stop positions, and a pivot arm having a first guideway, a stationary guide including a second guideway having a bent configuration and a turning point, a pivot axis for allowing the pivot arm to pivot with respect to the stationary guide, a guide member adapted to be guided in the first and second guideways, and at least one spring adapted to bias the guided member to a first stop position and a second stop position. The turning point is disposed between the first stop position and the second stop position and the pivot arm pivots with respect to the stationary guide between the first stop position and the second stop position. The pivot axis may be attached to the stationary guide. The turning point may force the guide member against a biasing force of the spring. The spring may force the guide member against one of the first stop position and the second stop position when the guide member moves away from the turning point. The spring may bias the guide member throughout its movement in the first and second guideways. The spring may bias the guide member throughout a pivoting movement of the pivot arm from the first stop position to the second stop position. The spring may include a torsion spring. The spring may include one end which applies pressure to the guide member and another end which applies pressure to the pivot arm.
The hinge may further include a retaining axis disposed on the pivot arm for holding the spring. The first guideway may include an L-shape slot and wherein the second guideway include an elongated slot. At least one of the pivot axis and the guide member may include a pin. The pivot arm may include two side walls and wherein the first guideway include an elongated slot disposed in each side wall, the slots being aligned with one another. The stationary guide may include two side walls and wherein the second guideway includes an L-shaped slot disposed in each side wall, the L-shaped slots being aligned with one another.
The invention also provides for a pivoting hinge joint having two end stop positions, including a pivot arm including two side walls and a first guideway, the first guideway including an elongated slot, a stationary guide including two side walls and a second guideway, the second guideway including an L-shaped slot and a turning point, a pivot axis pivotally connecting the pivot arm to the stationary guide, a guide member movably guided in each of the first and second guideways, and a spring biasing the guided member to a first stop position and a second stop position. The turning point is disposed between the first stop position and the second stop position and the pivot arm pivots with respect to the stationary guide from the first stop position to the second stop position while the spring biases the guide member.
The turning point may force the guide member against a biasing force of the spring. The spring may force the guide member against one of the first stop position and the second stop position when the guide member moves away from the turning point. The hinge may further include a retaining axis disposed on the pivot arm for holding the spring. At least one of the pivot axis and the guide member may include a pin. The stationary guide may include a U-shaped bracket with substantially perpendicular flanges extending from the side walls. The pivot arm may include an attachment flange having at least one hole.
Other exemplary embodiments and advantages of the present invention may be ascertained by reviewing the present disclosure and the accompanying drawing.
