Tripod with a sealed leg lock

A support suitable for supporting a device thereon comprising:

• (a) said support including at least one elongate hollow leg member at least partially supporting an apex, said apex defining a supporting surface suitable for supporting said device thereon;
• (b) said at least one elongate hollow leg member including a first leg segment and a second leg segment that are slidably movable relative to one another and wherein said at least one elongate hollow leg member includes a leg yoke at a terminal portion thereof;
• (c) a locking mechanism selectively inhibiting said slidably movable between said first and second leg segments, wherein said locking mechanism is configured to provide a substantially waterproof seal to prevent liquid from reaching the junction of said first leg segment and said second leg segment;
• (d) said locking mechanism includes an upper structure with a first recess defined therein and a first resiliently deformable member supported therein, a lower structure with a second recess defined therein and a second resiliently deformable member supported therein, wherein one of said first recess and said second recess open up toward said at least one elongate hollow leg member, wherein the other one of said first recess and said second recess open up away from said at least one elongate hollow leg member, wherein locking said locking mechanism compresses said first and second resiliently deformable member, wherein unlocking said locking mechanism decompresses said first and second resiliently deformable member;
• and
• (e) wherein said yoke defines a yoke opening therein that permits free-flow of air between an inside of said at least one elongate hollow leg member and an exterior of said yoke when said first leg segment and said second leg segment are slidably moved relative to one another thereby changing the volume of space defined within said at least one elongate hollow leg member.
