  • Patent number: 6857794
    Abstract: The invention relates to a camera stand head comprising a device (17, 18, 19, 20) for attenuating a tilting movement, and a device for compensating gravity torque occurring during the tilting movement. The device for compensating the gravity torque comprises at least one first, fixed bearing (4), at least one second bearing (5) which is connected to an inclinable part, and at least one torsion spring (7) having adjustable torsion rigidity. Said torsion spring is arranged between the bearings (4, 5) and comprises at least one spring bar (8), the axis of the spring bar being spatially offset in relation to the central axis (15) of the torsion spring (7). The characteristic curve (torque over angle of rotation) of the torsion spring extends essentially in a sinusoidal manner.

  • Patent number: 6082685
    Abstract: The invention relates to a telescopic stand comprising at least three telescopic units per stand leg, wherein a clamping device which can be actuated via just one clamping lever per stand leg is provided at two fixing locations (A, B) of the central stand unit. For this purpose, the clamping device is connected together at the two fixing locations (A, B) by an actuating bar (42). This considerably simplifies the stand's handling in that far fewer clamping levers with respect to the prior art have to be actuated.

  • Patent number: 5660373
    Abstract: The invention relates to a lifting apparatus with a carrying part (16, 18) which is connected via a cable (22) or the like with an actuating part for adjustment of the vertical position of the carrying part, in particular by means of interconnection of a pantograph (10), the actuating part comprising an actuating device with a gear transmission of which one transmission part, under the influence of the load of the carrying part (16, 18) or a load hanging from this, exerts a force on the other transmission part which couples this transmission part with an actuating element against a restoring force, wherein, upon actuation for the lifting of the carrying part (16, 18) out of the position in which the one transmission part does not exert any force on the other transmission part, the latter is moveable again into coupling engagement by means of the actuating element.

  • Patent number: 4697773
    Abstract: A vertically adjustable post for a tripod (1) for a film or television camera wherein a pneumatic piston-cylinder assembly (4) is used as a vertically adjustable element. In order to obtain uniform camera support over the whole range of adjustment of the pneumatic assembly (4), the piston rod (12) of the pneumatic assembly (4) is frusto conical. The piston rod (12) is sealed against the cylinder (14) of the pneumatic assembly (4) by means of a radially resilient seal (15) which adapts to the varying diameter of the piston rod (12).

  • Patent number: 4666112
    Abstract: A tripod (1) including three tripod legs (3) pivotably hinged on a carrier member (2) and of adjustable length. For fixing the length of the tripod legs (3) respective clamping devices (11) are provided. To adjust the height of the tripod, the clamping devices (11) on the tripod legs (3) can be actuated in common by means of a control handle (12). For this purpose three props (13) are hinged on the control handle (12), each one of said props being connected with one clamping device (11). In a lower stop position of the control handle (12), into which position the props (13) pass substantially horizontally, the length of all tripod legs (3) is fixed.

  • Patent number: 4657267
    Abstract: A motion picture or television camera stand is disposed on a running support consisting of a central body with three arms. The arms are provided each on their free ends with a set of wheels, the wheels being steerable through a central steering system which has a steering wheel disposed around the central column of the stand and fastened thereon, an upper central cogwheel mounted on the central column, a steering shaft rotatably mounted on the central column and extending parallel to the latter, with a pinion on its upper end cooperating with the upper central cogwheel and a pinion on its lower end cooperating with the lower pinion of the steering shaft in the central body of the support and one cogbelt drive from the lower central cogwheel to each cogwheel on the shafts bearing the running wheel sets. The stand is made to be removable from the support. Two of the arms of the support are foldable against the third arm.

  • Patent number: 4579436
    Abstract: A tripod (1) having a semispherical mounting tray (8) for mounting the semispherical portion (29) of a tripod head (7) for a film or television camera. The tripod head (7) has at its bottom a threaded pin (30) screwed with a threaded coupling (16) of a fastening element (10), whereby the semispherical portion (29) of the tripod head (7) can be clamped in the mounting tray (8). To be able easily to position horizontally the clamped tripod head (7), the fastening element (10) is made of several parts (11, 13, 14, 16, 19), the individual parts being compressed by a cup spring stack (13). By means of an eccentric (23, 24, 25) the cup spring stack (13) can be compressed to that the semispherical portion (29) of the tripod head can be moved with the screwed on threaded coupling (16) for leveling. If the eccentric is then forced out, the tripod head is locked in the new position by spring pressure.

  • Patent number: 4447033
    Abstract: In a mechanism or support for a television or movie camera which allows the camera to be tilted or pitched upwardly and downwardly, the weight of torque offered by the camera is counterbalanced by means of a series of accumulators or spring elements placed between the rotatable support for the camera and the stator portion of the support and adapted to be selectively engaged between the rotor and stator, depending upon the weight of the camera being used. Preferably each accumulator offers a restoring torque that is different from that of the other accumulators such that by selective engagement of various combinations of accumulators many different weights of cameras can be accommodated.
