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.

A height adjustable cane includes an upper tubular member (10) configured slidably to receive a second tubular member (20) in a telescoping manner. A plurality of apertures are formed in the first tubular member (10) which allows a button of a snap button assembly to pass therethrough and lock the tubular members (10,20) against relative movement. Using the push-button assembly and the telescopic feature, the length of the cane may be adjusted. Increased stability between the tubular members (10,20) is provided by a cam locking assembly (40) including a housing (42) receiving a cam member (44). The cam member (44) includes a lever (46) and a raised camming surface (70) that selectively engages an outer surface of the second tubular member (20).
摘要:
Die Erfindung betrifft einen längenverstellbaren Gabelbaum mit einem vorderen und einem hinteren Gabelbaumteil. Dabei sind Endabschnitte von Holmstücken (1) vorzugsweise des hinteren Gabelbaumteils in rohrförmige Holmstücke (2) des vorderen Gabelbaumteils eingesetzt und mit diesen in ausgewählter Einschublänge durch jeweils ein über eine Muffe (3) mit dem äußeren Holmstück (2) verbundenes Sperrglied (10, 11, 11′, 12, 13) kraftschlüssig verbindbar. Jedes in seiner Sperrstellung an der Außenseite des zugehörigen inneren Holmstücks (1) klemmend anliegende Sperrglied (10, 11, 11′, 12, 13) ist so an der Muffe (3) gelagert, daß es beim Herausziehen des inneren Holmstücks (1) aus dem äußeren in eine Freigabestellung bewegbar ist.
摘要:
A support device is provided including first and second telescopic members (4,6), the distal end or ends of the members engaging with a suitable surface in use. Locking means (20) are provided on the first and/or second members to lock the members in a required relative position. The locking means includes a locking portion (26) movably mounted on the first and/or second members and actuating means. The actuating means move the locking portion between a first unlocked position, wherein the locking portion (26) is movable relative to the first and/or second members, and a second locked position, wherein the locking portion (26) engages with the first and/or second members to lock the members in the required relative position.

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.
