Round mechanical advertising board

摘要

The round mechanical advertising board belongs to the advertising sector. Today's state of the art is as follows: in particular, as large-surface-area advertising means, there are the advertising boards which are made up of three metal strips to form a triangular segment. The present advertising board is based on this idea with triangular segments. It stands on a base slab (no. 6) with the aid of a leg (no. 9). A spindle (no. 2) is positioned in the centre of the leg. The entire body (no. 1) with two ball bearings (no. 3) is positioned on the spindle (no. 2). The triangular segments (no. 8), which have bolts (no. 5) at the top and bottom which are located in slide bearings (no. 4) are positioned in the round part of the body. Positioned at the bottom of the bolt are gear wheels (no. 10) which are connected to the gear wheel (no. 11) which is located beneath the body, on the leg. When the entire body rotates, then the triangular segments also revolve. <IMAGE>
