A telescopic stand is described and comprises at least two legs (2) and, for each leg, at least two elements (5, 6, 7) which are slidable telescopically relative to one another, locking means (12) on each leg (2), the locking means (12) being switchable between a locking condition and a release condition in which relative sliding between the elements of the respective leg (2) is prevented at least in one direction, or is unrestricted, respectively, and the locking means being switched to the release condition in at least one predetermined condition of relative positioning of the legs (2). The locking means comprises respective facing and opposed appendages (24b) which project towards one another from the respective legs (2) and, when pressed against one another, can interact with one another in the release condition when the legs (2) are gathered together.
A telescopic stand for optical or photographic apparatus and the like, comprising at least two legs (2) and, for each leg, at least two elements (5, 6, 7) which are slidable telescopically relative to one another, locking means (12) on each leg, the locking means (12) being switchable between a locking condition and a release condition in which relative sliding between the elements of the respective leg (2) is prevented at least in one direction, or is unrestricted, respectively, the locking means being switched to the release condition in at least one predetermined condition of relative positioning of the legs (2), characterized in that the locking means comprise respective facing and opposed appendages (24b) which project towards one another from the respective legs (2) and, when pressed against one another, can interact with one another in the release condition of the locking means (12) when the legs (2) are gathered together in the predetermined condition of relative positioning.
A telescopic stand according to one or more of the preceding claims in which the locking means (12) has a unidirectional effect and is active in the direction in which the telescopic elements (5, 6, 7) return into one another.
A telescopic stand according to one or more of the preceding claims in which a restraining means (11) is provided for restraining each leg (2) in the retracted position in the absence of an initial extension stress thereon.
