    摘要： An extendable leg (11) for a tripod (10) (for supporting an optical apparatus such as a video camera), the leg being V-shaped and having telescopic side members (15,16) to enable the length of the leg to be varied with hinge means to connect the side members to each other at an apex of the V, means to connect the side members to a head (12) of the tripod which allow the angle of the V to vary with extension and retraction of the leg, and clamping means (50) to clamp the side members at a required length; wherein the leg has a mechanism for controlling the extension and retraction of the side members when the locking means is released whereby the apex of the leg is constrained to move generally linearly in the lengthwise direction of the leg.

    摘要： A focus control device is adapted to adjust a camera lens. The device comprises a rotational input device (1), a variable gear ratio means (10) and a rotational output means so coupled to communicate a first rotational movement applied to said rotational input device to said variable gear ratio means (10) and to communicate a second rotational movement from said variable gear ratio means (10) to said rotational output means. The variable gear ratio means provides a variable adjustment of the angular velocity of said second rotational movement relative to the angular velocity of said first rotational movement.

    摘要： An extendable leg 10 for a tripod, the leg 10 comprises two or more leg-stages 11b, 11c, each leg-stage 11b, 11c moveable axially relative to one or more of the or each other leg-stages to lengthen or shorten the leg. The leg 10 includes a clamp assembly to releasably prevent the relative movement when the leg is at the desired length. The clamp assembly includes a leg brake 22a moveable between a first leg-stage locking position and a second leg-stage release position. In order to control movement of the leg brake 22a between the first and second positions, an actuation means 16 is provided. A cable 17 is operably connected at a first end to the actuation means 16 and at a second end to the leg brake 22a, such that operation of the actuation means 16 causes the cable 17 to move the leg brake 22a.

    摘要： A tripod (1) for mounting a camera or the like is disclosed. The tripod (1) comprises a support (5) having three legs (40) which are moveably mounted at a proximal end about the support (5) and circumferentially equidistant from each other. The legs (40) are moveable between an expanded configuration to support the tripod (1) and a folded configuration when the legs (40) lie adjacent to each other. In order to retain the legs in the folded configuration, at least one leg (40) includes a magnet (11) spaced distally along the leg (40) from the support. Each of the other two legs (40) includes a further magnet (12) or a magnetically attracted portion to magnetically engage the magnet (11) and releasably retain the tripod (1) in the folded configuration.
