<p>[Problem] This invention addresses the problem of developing a novel support leg mechanism in which it is possible to hold, in a stable manner, a sign or another object to be supported, even if the installation surface is uneven or otherwise irregular; and in which setting of leg sections can be performed with exceptional ease. [Solution] This support leg mechanism is characterized in comprising: a main body provided with an object to be supported; a movable body provided so as to be capable of sliding along the installation direction relative to the main body; and a plurality of movable legs connected individually and in a radial direction to the movable body via a one-way lock joint; the main body being provided with a stop position setting body for stopping the sliding of the movable body at an appropriate position; and, in supporting of the object to be supported, an allowance being made in discrepancies in the timing at which the movable legs come into contact with the ground, in the form of individual sliding actions of the one-way lock joints or a sliding action of the movable body relative to the main body, and the final fixation of the movable legs in contact with the ground being accomplished such that the movable body is brought into contact with the stop position setting body and the orientations of the movable legs are fixed in a single action.</p> |
