BRIEF SUMMARY
BACKGROUND OF THE INVENTION
The invention relates to a hinge with a catch mechanism, a hinge arm fastened to a furniture side-wall being linked by means of two hinge links to a hinge casing or the like fixed to a door, the hinge links being mounted on hinge axles on the hinge arm and in the hinge casing, and one of the hinge links being acted upon by a coil pressure spring pressing against the hinge link by means of an intermediate member arranged between the hinge link and the pressure spring, the intermediate member being a bush member receiving the pressure spring and pivotable around the hinge link axle.
Such hinges are widely used in modern furniture construction, particularly in the construction of modern kitchen furniture. In most cases the catch mechanism in the hinge replaces a separate closing device on the door, e.g. a snapping device, and thus has a favourable effect on the cost of the piece of furniture. Moreover, it prevents the door from remaining open unintentionally when it has been incompletely closed since the catch mechanism pulls the door into its final closed position when the door is within a certain angle to the closing plane.
SUMMARY OF THE INVENTION
It is the object of the invention to provide an improved hinge of the afore-mentioned type and to obtain a still more secure functioning than with prior art hinges having a catch mechanism and to make the production of the hinge more economical.
It is a further object of the invention to design the catch mechanism such that the forces acting thereon can be easily diverted and that the frictional forces acting between the catch mechanism and the other hinge parts are as low as possible.
According to the invention this is achieved by arranging a steel pin in the bush member, which is of plastic material, within the pressure spring, the steel pin having a head positioned between the pressure spring and the hinge link axle around which the bush member is pivotable, and the head having projections laterally resting against such hinge link axle.
An embodiment of the invention provides that the head is of circular shape, when viewed axially hereof.
It is advantageously provided that the projections of the head are crenature-like or that the projections are pyramid-shaped with one corner being directed towards the center of the circle.
To improve the fit of the steel pin, one, preferably two grooves extend in the head of the steel pin, each groove advantageously lying next to the side faces of two projections.
In the following embodiments of the invention will be described in more detail with reference to the drawings without restricting the invention to these embodiments.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS
A hinge includes a hinge arm 1 fastened to a mounting plate 4 by means of a fastening screw 2 which extends through a slot 3 in the hinge arm 1. The mounting plate 4 in the illustrated embodiment is screwed to a furniture side-wall 6 by means of screws 5, but any other manner of fastening, e.g. by means of dowels, could be used as well.
An adjusting screw 8 is mounted in a threaded bore 7 of the hinge arm 1, adjusting screw 8 in co-action with the fastening screw 2 permitting an adjustment of the hinge arm 1 and thus of the hinge in the direction of the breadth of the door joint.
A hinge casing 10 is inserted into a recess in a door 9, and the hinge casing 10 and the hinge arm 1 are linked by means of two hinge links 11,12 which are mounted on hinge axles, 13' in the hinge casing and on hinge axl
