ELONGATABLE SUPPORT |
摘要 |
An elongatable support has a lever actuating a fork for displacing a roller out of wedging engagement between an inclined surface of a head on a tube from which a bar can telescopingly extend, and a surface of this bar. To prevent inadvertent actuation of the lever, an abutment is interposed between the lever and the tube and can be withdrawn manually against gravitational and/or spring force to allow actuation of the lever.
