摘要: Camera mounting equipment comprising a wheeled base with a rotatable table mounted thereon. The rotatable table having a balanced pantographic arm pivoted thereon and means for controlling vertical and horizontal movement of a camera mounting platform attached to the other end of the arm. The equipment may be locked or unlocked in any combination of the three axes so that the camera mounting platform may have complete freedom of movement within its operational limits or may be limited to certain straight line or planar movement. The equipment is also counterbalanced and the arm may be remotely controlled using low power motors.

摘要: A pan and tilt head for a TV or video camera mounting (10) comprises two drag/damper devices, one for controlling the pan movement and the other for controlling the tilt movement. Each device may comprise a fixed central shaft (18), a first set of spaced plates (22) secured to the shaft, a second set (24) secured to a rotatable housing (20), and a third set (26) interleaved between the first and second sets. When the plates are immersed in a viscous fluid and one member is moved, the characteristics are such that the forque increases linearly with speed from zero up to a given speed, and then remains substantially constant above the speed.

摘要: A height adjustable load carrying platform (7) wheel mounted for steering or crabbing movement and comprising at least three concertainable lazy tongs lattices of struts (5) forming a 3 sided pyramid which can be raised and lowered manually or under power, and includes a counterbalance mechanism (67). The structure replaces a conventional pedestal support for a camera or the like (such as T.V. camera) and is capable of being extended up to normal pedestal height, but is also capable of contracting to a lower minimum height than that of a conventional pedestal. Three and four axis hinges are described to permit the articulation at the corners.

摘要: A load counterbalancing mechanism wherein the mechanically actuated interaction of two independent spring systems, one of which is adjustable, provides the necessary counterbalancing forces to balance the torque forces set up by a load being raised, lowered or tilted about a point on which it is pivoted. Various loads are therefore accommodated by the adjustable spring system.

摘要: A tiltable mounting for a payload includes a base (10), a support member (15) for supporting the payload thereon, the support member being tiltable about a horizontal axis (14) on the base for tilting about each side of a top dead center position about said horizontal axis, and a torque generating mechanism (17) mounted on the base and acting on the tiltable support to generate a torque in response to tilting of the support equal and opposite to the out of balance moment of the support with its payload to hold the support balanced in any position of movement about said axis. A plurality of torque generating units (20, 21) are provided each generating a torque which varies sinusoidaly with displacement, and a mechanism (22, 23, 31, 32, 35, 36, 37) provided for adjusting the phase angle between the torque generating means to vary the collective amplitude of the torque generating mechanism to suit the weight of the payload on the support member.

摘要: The need for readjustment of clamps due to wear and tear is overcome by the provision of clamping means comprising a first member (16) movable relative to a housing (10) to effect clamping; torque limiting drive means (30,44) rotatable to effect that movement; and lost motion stop means (50,60) rotatable by the drive means into a first stop position in which continued rotation of the drive means is prevented and, through reverse rotation of the drive means, into a second stop position in which continued reverse rotation of the drive means is prevented. This clamping means can be used in particular to clamp telescoping legs, for instance on camera tripods.

摘要: A control device for a tiltable mounting head, such as the mounting head for a camera, has a three element pantographic linkage including a rigid control arm of which an intermediate point is constrained to move along a horizontal path. One end of the arm is pivotally mounted to an arm carrying the tiltable head, while the other end is pivotally mounted to a locating arm whose remote end is pivoted to fixed structure. The relative angular position of the two arms is controlled by two parallelogram linkages with different degrees of fold and having the central arm in common, whereby one of the two linkages is always laterally spaced from the arm. Alternatively the two arms may be secured to respective sprockets pivoted to the arm and connected together by a chain.
