Patent

CA 2342312

The present invention provides a support assembly for a lighting fixture that allows for the adjustment and positioning of a lamp about both a horizontal and a vertical axis using only one locking mechanism. The support assembly includes a first support member that is pivotably attached to a second support member. The support assembly also includes a cylindrical sleeve to which the second support member is adjustably engaged. Both support members include at least one leg extending therefrom. The locking mechanism includes a pivoting brake shoe that can engage the cylindrical sleeve so as to secure the lamp into position about a vertical axis. The locking mechanism also includes a thumbscrew that is housed within a slot defined within a leg of the first support member, and that engages both the brake shoe and a leg on the second support member.

La présente invention présente un mécanisme de support pour un appareil d'éclairage qui permet le réglage et le positionnement d'une lampe sur à la fois un axe horizontal et un axe vertical en utilisant uniquement un dispositif de blocage. Le système de support comprend un premier élément de support qui est fixé de façon pivotante à un deuxième élément de support. Le mécanisme de support comprend également un manchon cylindrique auquel le deuxième élément de support est fixé de façon réglable. Les deux éléments de support comprennent au moins une patte s'étendant à partir de ceux-ci. Le mécanisme de blocage comprend un sabot de frein pivotant qui peut engager le manchon cylindrique de manière à assurer que la lampe soit en position sur un axe vertical. Le mécanisme de blocage comprend également une vis moletée qui est logée dans un trou défini dans une patte du premier élément de support, et qui engage à la fois le sabot de frein et une patte sur le deuxième élément de support.
