DETACHABLE HANDLE FASTENERS FOR BROOMS OR SCRUBBERS

The innovation concerns a detachable handle attachment for Brooms or scrubbers, with a pair embedded in the end of the handle Forks with cranked ends in The bores of the brush body are inserted, and one each on the 2 crankings running parallel to the brush body Hairpin spring is mounted, with both springs to each other are wound in opposite directions and each with a short feather arm reach through a holding hole in the broom body and hook one end of a claw there, while the longer one Arm of each hairpin spring ends in an open loop end, with bias against the adjacent fork prong,

An embodiment known from German patent specification 439 6 ^ 3 This genus has the disadvantage that the two hairpin springs are inadvertently aligned with one another Slope of the ends can be threaded onto the offset sections of the fork prongs during assembly, whereby only one of the two half-eyelet ends shows the outside instead of the inside, the difference with a cursory assembly easily overlooked /. A reliable fixation of the jjossit = oüsr bciiruioiisrlccrpsrs is then xiiciit; iseiir rnogiicii.

But even with correct pre-assembly of the hairpin springs it is difficult to clamp them on the lance arms after attaching the brush body and with the open eyelet ends hook behind the fork arms in question. Breaking such a connection is even more difficult.

In order to avoid these deficiencies, it is already known to let the two pedal organs merge into one another at the end of the handle and to tension them together with a toggle lever (DBGM 1 868 73 * 0, or with a sliding ring made of sheet metal that cannot be lost on the handle end) to lock both clamp-like retaining springs in the tensioned state (DBGM 7 028 Ο8θ) or to lock only one central retaining spring in the same way (DBGM 1 608 817) known handle attachment of the type mentioned (German patent specification k39 6 ^ 3). Furthermore, the sheet metal sliding ring tends to tilt and jam on the handle end, so that you have to operate it quite vigorously with the thumb to lock and unlock, with one easy to the There is also the possibility that the hairpin springs according to DBGM 7 028 080 can be inserted into the brush body in an installation position incorrect by 180 °, despite its one-piece connection, which can then also no longer be fixed to the handle.

To avoid these deficiencies is a pin attachment of the genus mentioned at the outset suggested that the long arms of hairpin feathers near their open Opposite bulges form eyelet probes and underneath them are bridged by an attached clip, preferably made of plastic. The bulges leave during assembly can clearly see whether the hairpins are correct, namely with opposite turning tendency, on which the forks have been threaded, and these bulges also provide comfortable Handling for loosening and tensioning the long Feöerine, if about one worn brush body against one to be replaced with a new one. Finally, these bulges ensure that the mentioned Klaaunsr 3 «far below at = · is brought and kept that they reliably the target distance of the lower spring ends according to the distance of the associated holes fixed in the brush body, making its assembly is very easy.

The innovation may be illustrated using the exemplary embodiment shown schematically and graphically in the figure will.
