Abstract

A support stand for a camera or other optical device comprises a head portion supported by support legs comprising first and second telescopically related tube portions, the inner tube portion forming the upper part of the respective leg and the outer tube portion forming the lower part. A fixing device for locking the tube portions of each leg relative to each other comprises an actuating member, a connecting rod and a clamping arrangement connected to the actuating member by the connecting rod and comprising at least one clamping cone member and at least one pressure element. The actuating member is carried on the inner tube portion in the vicinity of the support head portion of the stand. Actuation of the actuating member causes the pressure element to be expanded by displacement of the cone member until the pressure element bears against the inside surface of the outer tube portion, thereby to secure it in position relative to the inner tube portion.

Claims5

Dependent claims

A stand for an item of equipment, comprising a head portion, a plurality of support legs connected to the head portion, each of said support legs comprising inner and outer tubular portions displaceable in telescopic relationship with each other, said inner tube portion connected to said head portion and said outer portion connected to the inner tube portion;

and a fixing means for fixing the tube portions of each support leg relative to each other, comprising an actuating member on the inner tube portion, a connecting member operatively connected to the actuating member and a clamping arrangement operable by said connecting member and which includes at least one clamping cone member on the connecting member and on the inner tube portion at least one pressure element co-operable with the cone member;
said actuating member being pivotably movable between locking, normal operating and release positions wherein the clamping arrangement in said locking position of said actuating member provides a fixed frictional connection between the inner and outer tube portions and in said release position releases said connection between the inner and outer tube portions whereby said outer tube portion is freely slidable relative to the inner tube portion, while the clamping arrangement in said normal operating position of the actuating member provides for a sliding frictional relationship between the first and second tube portions.
