Abstract
A locking device including a spring, such as a static load spring, and a locking part, such as a locking pin or a locking disc, for locking two elements to one another includes connecting elements and U-shaped portions in a sequence. The U-shaped portions connect two connecting elements at a first end of said two connecting elements, respectively, wherein the two connecting elements converges towards each other towards a second end of the two connecting elements, respectively, in a non-compressed state, such that the sequence of connecting elements and U-shaped portions form a meandering shape.
Claims21
A locking device comprising a spring and a locking part, for locking two elements to one another, wherein the spring comprises a U-shaped portion and an adjacent U-shaped portion disposed along a main longitudinal axis of the locking device, each U-shaped portion comprising a pair of opposing legs extending in a direction transverse to the longitudinal axis and a bottom extending therebetween, wherein one of the opposing legs of the U-shaped portion is connected to one of the opposing legs of the adjacent U-shaped portion, wherein a first crosscut at the bottom of the U-shaped portion comprises an outer surface which is of a rounded shape and an opposite inner surface which is essentially straight, and wherein a second crosscut at the bottom of the adjacent U-shaped portion comprises an outer surface which is of a rounded shape and an opposite inner surface which is essentially straight, the first and second crosscuts being perpendicular to the main longitudinal axis of the locking device.
