DE19540187A1 - Strengthened door for passenger vehicles - Google Patents

Abstract

The one-piece frame (1) avoids the need for gluing, welding, screws or other types of connection included. There is a crevice into and out of which the glass sheet window moves. The strengthened door section is joined at the ends with the remaining door structure with the door guidance splints. The strengthened door surrounds the glass sheet and can in different forms become a distinct part of the door or the entire door structure.

Description

Main feature of the patent proposal: The door reinforcement consists of, in front of and behind the pane a single part, which has a recess in the middle, whereby the glass pane can be moved. There are no sweat, glue, or other connections that the Connect areas in front of and behind the pane. The reinforcement is at the ends with the rest Door structure and, depending on the variant and location in the door, also with the window guide rails (which are carried out through the recess) connected. The reinforcement surrounds the glass pane from all sides. If the one-piece door reinforcement is in the shaft area (and depending on the version also in the hinge areas), has the elongated Recess (which is located in the middle of the one-piece door reinforcement) a corresponding Shape to allow the passage and fastening of the window guide rails.

The reinforcement described above can be used as a shaft reinforcement and also as a door impact beam in Area of the upper as well as the lower hinge.

Other locations such as B. at the level of the sill, or between the hinges, or others Positions are also possible if required. The one-piece shaft reinforcement, e.g. B. forms at the same time the door structure in the shaft area and can with the upper hinge, at one end, and with the Lock, at the other end, can be connected directly. The reinforcement in the area of Door impact beam, horizontal or inclined, can go out of and with the lower hinge be directly connected. It can also form the door structure in this area.

The reinforcement profile chambers are filled with foam or plastic parts as required. Additional local stiffening elements are easy to use. The door reinforcement is depending on the area of use (shaft area, door impact beam, hinge level, sill, etc.) Different materials such as Al, Mg, steel, plastic with or without glass fiber reinforcement are conceivable. The following technologies are possible: extrusion (Al, Mg); Casting (Al, Mg); Forging (Al, Mg) profiling, rolling (steel, Al); Deep drawing (steel); Injection molding (plastic), presses etc.

Claims (1)

Door reinforcement, characterized in that it consists of a single piece (without welding, adhesive, rivet, screw or other connections), and that it has a recess in the middle, which allows the movement of the glass pane of the door (when opening and Closing the glass pane) allowed, and the implementation and attachment of the window rails allows.
