Abstract

A lid stay for holding a lid of a piece of furniture has a first arm (1) and a second arm (2) pivotably connected to the first arm (1). The arms (1, 2) are movable between an open position and a closed position around a swivel axis (4). A friction mechanism (9, 10) is active between the first arm (1) and the second arm (2). A spring mechanism acts upon the second arm (2) in the direction towards the open position or in the direction towards the closed position. The spring mechanism influences the frictional force that acts upon the friction means (9, 10).

Claims

1. A lid stay, comprising:

a first arm, said first arm includes a housing;

a second arm pivotably connected to the first arm around a swivel axis, said first and second arms movable between an open position and a closed position;

friction means effective between the first arm and the second arm, said friction means including an adjustment slider movably supported relative to the first arm and connected to the second arm, said adjustment slider movably supported in said housing and in frictional contact with inner faces of said housing, and said adjustment slider including a first slider part and a second slider part, said first and second slider parts in frictional contact with said inner faces of the housing; and

spring means for urging said second arm in direction to the open position or in direction to the closed position and said spring means acting upon the friction means influencing frictional force, said spring means including compression springs acting upon the second arm via the adjustment slider, and said spring means positioned in said housing, and said spring means supported against the second slider part, the first slider part connected to the second arm, the first slider part abutting the second slider part via an adjustment face, said adjustment face abutting an abutment face of the second slider part, and said adjustment face and abutment face being arranged at an angle to the adjustment direction of the adjustment slider.

2. The lid stay according to claim 1, wherein the second arm includes a lever pivotably connected to the second arm around an axis of rotation, said axis of rotation positioned eccentrically with respect to the swivel axis, said axis of rotation extends parallel to the swivel axis, and said lever in the adjustment direction of the adjustment slider is rigidly connected to the adjustment slider part and said lever being movably connected to the adjustment slider transverse to the adjustment direction.
