Description

furniture hinge

technical field

The invention relates to a furniture hinge.

Background technique

Generally speaking, the four-link furniture hinge facilitates the opening or closing of a movable component (such as a door panel) of furniture relative to a fixed component (such as a cabinet). For example, US Patent No. US 6,401,298 B1 discloses a furniture hinge comprising a hinge housing and a hinge arm that can be mounted to different furniture components, and the hinge housing and the hinge arm pass through several hinge links, such as Four connecting rods (or shafts) 9, 10, 11, 12 are connected to each other. Wherein, a pressure spring (such as a leg spring, leg spring) acts on a hinge link, and a part of the pressure spring surrounds (encircle) on a hinge axis (hinge axle), so that the pressure spring is installed on the hinge axis . This patent is hereby incorporated by reference. However, Figure 3 (FIG.3) of the aforementioned patents shows that a U-shaped leg spring (U-shaped leg spring) 13 is installed and wrapped around or wrapped around a hinge axis (hinge axle) 11, if the When the U-shaped foot spring is not assembled with the third shaft, the U-shaped foot spring sticks to the hinge arm 1 and cannot be fixed at a predetermined position.

Alternatively, as French Patent Publication No. FR 2482998 A2 discloses a hinge comprising four shafts a, b, c, d, wherein, as shown in Figures 1 and 2 of this patent, a spring 40 surrounds or covers A shaft d is used to provide elastic force for the opening or closing of the movable part 2 relative to the fixed part 10 .

Alternatively, Japanese Patent Application JP S60148472 U discloses a hinge, as shown in the drawing, which includes a leaf spring 52 surrounding or covering a shaft 51 to provide elastic force for opening or closing of the hinge.

Alternatively, as US Patent No. US 5022117 A discloses a furniture hinge with a closing mechanism, a part of the leaf spring 34 is held fixed by a pin 32 , and the leaf spring 34 surrounds another pin 37 .

It can be seen that, in the above-mentioned four patent references, the springs are substantially installed on the rod body of the four-link (axle or pin) by surrounding and covering. However, depending on the market demand, sometimes considering the cost of materials or the way the spring is installed on the hinge, it will come into contact with one of the four linkages (shaft or pin), which may cause the hinge to open or close for a long time. wear or wear.

It can be seen that the aforementioned patents still need to be improved, and in view of this, the present invention is produced.
