Title: Hinge assembly for connecting a door to a frame of a furniture body

Description:
BACKGROUND OF THE INVENTION 
     1. Field of the Invention 
     The invention relates to a hinge including an intermediate part for quick connection between a door and a frame of a furniture body, a hinge casing insertable into a bore in the door and a mounting body fastenable to the frame and carrying a hinge arm by means of the intermediate part, the hinge arm and the intermediate part being held by a screw and the hinge arm being connected with the hinge casing by means of a hinge axle or by means of hinge axles and hinge links. 
     Furniture hinges of this kind are used with furniture bodies which have side walls that are so thin that they cannot carry the load of the door and that, hence, include a separate frame carrying the door. 
     2. Summary of the Invention 
     It is the object of the invention to provide a hinge of this kind in which the hinge arm with the intermediate part can be quickly positioned on the mounting body and easily fastened thereto, when final mounting operations are carried out. 
     According to the invention, this is achieved by adapting the intermediate part to engage in grooves in the mounting body and by clamping holding projections of the mounting body between the hinge arm and the intermediate part by means of the screw. 
     The advantage that the holding projections of the mounting body are clamped between the hinge arm and the intermediate part has the effect that the holding projections are not exposed to loads, such as is the case with prior art hinges in which the intermediate part is by means of a screw pressed away from the bottom of the mounting body towards the holding projections. Furthermore, prior art hinges require a screw for holding the intermediate part at the mounting body and a second screw for holding the hinge arm at the intermediate flange. 
     An advantageous embodiment of the invention provides that a spring is arranged between the intermediate part and the hinge arm. The spring is advantageously a pressure spring extending around the screw. The advantage of the spring is that the intermediate part and the hinge arm are spaced from each other before being mounted so that this unit can easily be placed on the mounting body. 
     A further embodiment of the invention provides that the holding projections of the mounting body are clamped between noses or flanges of the intermediate part and the side flanges or walls of the hinge arm which has a shaped U-profile. 
    
    
     BRIEF DESCRIPTION OF THE DRAWINGS 
     In the following an embodiment of the invention will be described in greater detail and with reference to the accompanying drawings, wherein: without being limited thereto. 
     FIG. 1 is a horizontal sectional view of a hinge according to the invention, 
     FIG. 2 is a vertical sectional view of the hinge according to the invention, and 
     FIG. 3 is an exploded view, partially in section, of the parts of the hinge the parts being shown apart partly in section. 
    
    
     DESCRIPTION OF THE PREFERRED EMBODIMENT 
     A mounting body 1 is fastened to a frame 8 by means of screws or dowels in a conventional manner. 
     The mounting body 1 is provided with holding projections 10 delimiting grooves 11. An intermediate part 2 is inserted into grooves 11 and held therein by noses or flanges 12. 
     The intermediate part 2 has a female thread into which a screw 4 is screwed. 
     A hinge arm 3 is mounted on the intermediate part 2, i.e. it is held by means of the screw 4 extending through a hole 13 in the hinge arm. Lateral flanges or walls 3&#39; of the hinge arm 3, which has a U-profile as can particularly be seen in FIG. 2, together with the noses 12 of the intermediate part 2 clamp the holding projections 10 of the mounting body when the screw 4 is tightened. 
     The hinge arm 3 is pivotally connected with a hinge casing 5 by means of a hinge axle 14. 
     If, in the illustrated embodiment, the holding projections 10 and the grooves 11 are horizontally aligned, an adjustment of a door 7 in the direction of the breadth of the door joint is possible by displacing the hinge arm 3 and the intermediate part 2 with respect to and along the mounting body 1. 
     In order to facilitate positioning of the unit comprising hinge arm 3 and intermediate part 2, a coil spring 6 is arranged between the intermediate part 2 and the hinge arm 3, the coil spring being positioned around the screw 4.
