INSERTION CONNECTION DEVICE FOR VACUUM CLEANER PIPE Russian patent published in 2005 - IPC

FIELD: mechanical engineering, in particular insertion connection equipment for vacuum cleaner pipe.

SUBSTANCE: insertion connection device is adapted for connecting of adapter tubular part to suction tool, such as suction nozzle, suction brush, and at other side for detachable connection of handle arranged at free end of suction hose to insertion end of pipe of apparatus with telescopic pipe. Device has coupling member defining receptacle member, into which is axially inserted and detachably fastened insertion end of pipe by fastening means. Fastening means has retainer positioned for displacement on coupling member, and slot provided on insertion end of pipe, said retainer being releasably inserted into said slot. Control member is positioned for axial displacement on coupling member in opposite axial directions from neutral position on axis of locking surface of control member to counteract spring returning force. When control member locking surface is in its neutral position on axis, it holds retainer in locking position and releases retainer at each displacement from neutral position on axis to unlocking position. First control surface connected with end side of insertion end of pipe is adapted for moving retainer in conjunction with coupling member relative to locking surface in direction of insertion of pipe, when insertion end of pipe is inserted, for unlocking retainer and releasing thereof to provide detachable fastening in slot under retainer, with which second control surface is connected. On withdrawal of insertion end of pipe from receptacle member, second control surface moves retainer in conjunction with coupling member relative to locking surface in direction of withdrawal for unlocking said retainer.

EFFECT: simplified assembling and disassembling of insertion device.
