SCISSOR-TYPE GUIDE WITH SPRING BIASING AID
A scissor-type guide (20) for guiding extension and retraction of lamellae, said scissor-type guide (20) comprising - at least two scissor links (23, 123), each scissor link comprising a first scissor member (24, 124) and a second scissor member (25, 125), - a first rotational joint (26, 126) formed between the first and second scissor members (24, 124; 25, 125) of each one of the scissor links (23, 123), and - two second rotational joints (27) formed between first ends (24', 25') of a first scissor member (24) and a second scissor member (25) of a first scissor link (23), and respective ones of second ends (124", 125") of a first scissor member (124) and a second scissor member (125) of a neighbouring, second scissor link (123); wherein a spring member (300) is formed between the first scissor member (24, 124) and the second scissor member (25, 125) at a first rotational joint (26, 126) of the scissor-type guide (20), or between a first scissor member (24) of the first scissor link (23) and the first scissor member (124) of a neighbouring second scissor link (123) at a second rotational joint (27) of the scissor-type guide (20).
L'invention concerne un guide de type ciseaux (20) servant à guider le déploiement et le retrait de lamelles, ledit guide de type ciseaux (20) comprenant - au moins deux liaisons (23, 123) de ciseaux, chaque liaison de ciseaux comprenant un premier élément ciseau (24, 124) et un second élément ciseau (25, 125), - une première articulation de rotation (26, 126) formée entre les premier et second éléments ciseaux (24, 124 ; 25, 125) de chacune des liaisons (23, 123) de ciseaux, et - deux secondes articulations de rotation (27) formées entre des premières extrémités (24', 25') d'un premier élément ciseau (24) et d'un second élément ciseau (25) d'une première liaison (23) de ciseaux, et des secondes extrémités respectives (124", 125") d'un premier élément ciseau (124) et d'un second élément ciseau (125) d'une seconde liaison (123) de ciseaux voisine ; un élément ressort (300) formé entre le premier élément ciseau (24, 124) et le second élément ciseau (25, 125) au niveau d'une première articulation de rotation (26, 126) du guide de type ciseaux (20), ou entre un premier élément ciseau (24) de la première liaison (23) de ciseaux et du premier élément ciseau (124) d'une seconde liaison (123) de ciseaux voisine au niveau d'une seconde articulation de rotation (27) du guide de type ciseaux (20).
