HANDLE MOUNTING MEANS FOR POWER DRIVEN VACUUM CLEANER |
摘要 |
<p>An improved mounting structure for movably mounting the handle of a power driven vacuum cleaner including spring biasing structure urging the handle to a central neutral position and permitting the user of the vacuum cleaner to effect selective forward and rearward movement of the vacuum cleaner by suitable manipulation of the handle against the action of the spring biasing structure. The spring biasing structure is defined by a cartridge which is mounted in a tubular portion of the handle. Improved bearing structures are provided for providing facilitated longitudinal reciprocation of the handle for facilitated control of the forward and reverse operation of the vacuum cleaner.</p> |
