发明名称 Instrument stand
摘要 In order to secure the ends of the legs for the stand in the leg ferrule caps so that they are not loosened readily by shrinkage of the wooden leg material, the legs have a number of spacing pins extending crosswise through them where they are clamped. The pins are of a material which is more rigid than the wood of the legs themselves and are thus subjected to a greater clamping pressure. As a result of the orientation of the pins, perpendicular to the axis of the legs but angularly displaced from each other, the legs are held securely with their longitudinal axis remaining in the initial clamping position even after shrinkage of the leg wood. A particular clamping device utilizing a wedge is also described.
