Abstract

A hinge has a hinge arm (2) connected to a hinge head (8) by using outside and inside hinge levers forming four corners of a joint with four joint shafts (4, 5, 7). One joint lever (9) as a double arm lever is formed by an arm (23) overhung and directed in the hinge arm (2). The arm (23) is pressed by a spring (11) supported in the hinge arm (2), the arm (23) includes two lateral stems (13) aligned perpendicular to the joint shafts (4, 5, 7) and the spring (11) is formed to press a cylindrical metal pivot (10) held between the lateral stems (13) of the arm (23) of the joint lever (9) overhung and protruded in the hinge arm (2).

Description

Hinge

The present invention relates to a kind of hinge with a hinge arms, hinge arms links to each other with hinge box by means of an inside and outside rotating lever that constitutes a quadric chain with four hinge axis, one of them rotating lever is made has an arm that points to hinge arms with overhanging, it is by a spring-loaded that is bearing in the hinge arms, and has two side plates perpendicular to hinge axis.

This hinge with closing organ of spring formation has such advantage: even the movement of closing the door unintentionally also can be moved door to fastening position reliably.Secondly can tightly install without door lock or knocker.In AT 392 996B, can see the example of the hinge that a kind of like this its closing organ is made of a butterfly spring.

The objective of the invention is, improve the described such hinge of beginning as follows, make that prolonged the application life of closing organ and rotating lever.

Solve like this by this task of the present invention, make spring be pressed in particularly to be fixed on rotating lever to stretch on the cylindrical metal pin between the arm side plate of hinge arms.

By make the metallic pin to adopt rotating lever itself is more senior and more wear-resisting thus material to make by structure of the present invention.Can improve significantly the life-span of hinge thus, and not increase cost during fabrication significantly.The hinges known medi-spring acts directly on the rotating lever, and this can cause the rapid wearing of rotating lever.

In order to reach the well secured of metallic pin, in one embodiment of the invention, to consider on the side plate free end, to establish a breach, metallic pin is fixed in wherein, and metallic pin and side plate are welded to each other or soldering.

The best metal surface is equipped with kollag, for example a titanium nitride coating.Can reduce the friction between spring and the metallic pin in this way.

Spring preferably adopts butterfly spring, and it is bearing on the metallic pin with one arm, is bearing on the hinge arms with its second arm.

By means of the figure in the accompanying drawing one embodiment of the present of invention are illustrated below.

Fig. 1 represents the schematic diagram that has by hinge furniture body of the present invention a: Fig. 2 schematically and take expression hinge of the present invention apart, and Fig. 3 represents that the vertical profile of the hinge when fastening position of the present invention looks; Fig. 4 represents that wherein furniture door is in the closed position by looking by the vertical profile of hinge of the present invention, furniture side arm and furniture door; Fig. 5 represents the view identical with Fig. 4, and wherein furniture door is in not open position; Fig. 6 represents the view same with Figure 4 and 5, and wherein furniture door is in full open position.

As seen from the figure, hinge arms 2 is fixed on the furniture side arm 17 by means of base plate 14, and hinge box 8 is installed in the hole of furniture door 15.Hinge arms 2 and hinge box 8 interconnect by an interior rotating lever 6 and an inner rotary lever 9.

Interior rotating lever 6 is hinged on the hinge arms 2 by means of an axle 4, and inner rotary lever 9 is hinged on the hinge arms by means of axle 5.Two rotating

levers

6,9 are bearing on the hinge axis that is made of U-shaped knee 7 on hinge box one side.

Hinge arms 2 is strained on base plate 14 by means of a clamping screw 18 and a slit adjustment screw 1, and base plate 14 directly is fixed on the furniture sidewall 17.

The closing organ of hinge is made of a butterfly spring 11, and butterfly spring is bearing on the axle 3 of hinge arms 2.The inner rotary lever is made U-shaped basically, and has two side plates 13.

Interior rotating lever 6 is done slabbing, and it has a crimping 19 on one side in hinge box, is bearing on the U-shaped bar 7 by means of rotating lever in it 6, just on the hinge box hinge axis on one side.

Rotating lever 6 is provided with two wing plates 16 in hinge arms one side, and they are perpendicular to hinge

axis

4,5, and has hole or punching out hole, and the hinge axis 4 of hinge arms 2 passes these holes, and rotating lever 6 is bearing on the hinge arms 2 in making thus.

Butterfly spring 11 has two arms 21,22.Secondly butterfly spring 11 is provided with two crimpings, and they are made of two coil springs respectively.The arm 21 (mutually) of the butterfly spring 11 of crimping by making dual bar connects.The second arm of butterfly spring 11 is made of the spring end of the both sides of butterfly spring 11, and is bearing on the middle crosspiece of the hinge arms 2 of making the U-shaped profile.

The arm 21 that butterfly spring 11 is made dual bar is pressed on the inner rotary lever 9.Here the arm 21 of butterfly spring 11 directly leans against on the metallic pin 10, and metallic pin is fixed between two side poles 13 of inner rotary lever 9.Inner rotary lever 9 is made both arms shape lever, with a cantilever stretch into the arm 23 of hinge arms 2.This arm 23 only is made of the side plate 13 of outward turning pivoted arm 9 in the present embodiment.At its free end epipleural 13 breach is arranged, metallic pin 10 is installed in this breach, metallic pin 10 preferably weld with the side plates 13 of arm 23 or inner rotary lever 9 or soldering together.

Inner rotary lever 9 itself is made by common steel plate, and metallic pin 9 is by valuable high-abrasive material, and for example chrome-nickel or chrome alum alloy are made.Also can adopt manganese steel.

In order to reduce the friction between butterfly spring 11 and the metallic pin 10, for example titanium nitride, titanium carbide, chromium nitride or tungsten carbide coating can be coated in metallic pin 10 surfaces.Secondly the surface of metallic pin 10 can be provided with kollag, for example molybdenum bisuphide.

On the furniture sidewall, hinge box 8 has a flange to the base plate 14 of hinge by means of screw or dowel fixes, and it is provided with the punching out hole, the screw that comes that do not draw passes this hole, and this screw has been strengthened hinge box 8 fixing on furniture door 15.
