An angle adjusting mechanism between a first member placeable on a support post and a second member to which a support standard is attached for adjusting the angle of the standard with respect to the post. The first member having first and second spaced apart support walls. The second member having a third support wall disposed between the first and second walls. At least one friction plate at each side of the third wall and between the first and second walls. A holding metal fitting at the side of one friction plate and engageable with the inside of the second support wall, the holding metal fitting being moveable toward and away from the second wall and being prevented from moving across the second wall. A bolt and nut connection pulling the first and second support walls toward each other. The holding metal fitting uniformly distributing the compressive force around the friction plate. Rotation of the friction plate and/or of the holding metal fitting is prevented as the angle between the first and second members is adjusted, either by a splined connection between the holding fitting and the opening for the tubular part of the holding fitting in the second wall or through projections from the friction disks being received in slots in the first and second members. |
