发明名称 Attachment and detachment of a weight to a boom cymbal stand
摘要 An attachment and detachment mechanism for a weight held on the boom rod of a boom cymbal stand. The weight has a hole in one side over which a cover is installed and there is an aligned hole in the cover. A spring operated boom rod installation and detaching lever which is disposed between the cover and the side of the weight, has a window through it so that the boom rod can be installed through the cover, the window and into the hole in the weight. The periphery of the window is engagable in a groove in the boom rod under the bias of a spring which moves the lever to cause such engagement. Moving the lever counter to the spring force releases the boom rod so that it can be withdrawn from the hole in the weight and permits insertion of the boom rod in the hole.
