Definitions

  • the invention refers to a collapsible handle to be used on tools for room cleaning, such as brooms, brushes of other, which -as a princi­ple- can be mounted without interposition parts, allows a high resi­stance when connected and determines a retention effect apt to carry out a solidarily binding working condition.
  • Some connecting devices are well known which, for the use, show in­terposition parts working as activators of binding means.
  • One of the­se systems uses an automatism with a spring pivot which, when gett­ing outwards, blocks the connecting parts in binding seat.
  • a ring-shaped part is used which can be put in expansion by rotating in advancement a connecting coaxial part.
  • These systems re­quire rather high costs and their fragility, with the time, brings to inefficiency or anyhow to degradation of the means due to the parts disjunction.
  • the conventional means for directly connect­ing the parts consists in carrying out a coaxial composibility by screw­ing a threaded pin in a spiral seat of the coaxial part.
  • the invention carri­es out the solution of the above mentioned problems by adopting a new conception system in carrying out the screwing seat of the connecting coaxial component.
  • This system avoids the structural weakening of the said part and determines a balanced retention effect to the conventio­nal disengaging overstressing on the handle.
  • the handle can be decomposed in two or more longitudi­nal lengths which can be connected by screwing.
  • these ones are brought into direct screwing up to the beating limit of the threaded pin on the axial part into the corresponding screwing seat with special conformation of the coaxial part.
  • This seat consists of counterposed sets of screw-shaped lengths, singular­ly emerging from the inside wall of the cylindrical structure.
  • the proceeding avoids to weaken the coaxial part, which would occur if carrying out the complete screwing of this part; furthermore, by means of the counterposed sets of bombed reliefs, which singularly press into the helical furrows of the axial body, it performs a perm­anent balanced retention effect which tends to perform a solidarily binding condition between the connection parts. This because the push­ ing and, therefore, pressing effect of a bombed part emerging from an inside cylindrical wall is stronger than the one of a plate structure with helical shaping.
  • FIG. 1 represents the detached connecting parts seen from one side in order to evidence the furrows that inside determine the set of the threading relief lengths.
  • Fig. 2 is the view of the same components observed from the other side to point out the relevant other set of threading furrows.
  • Fig. 3 the above components are in connection.
  • Fig. 4 is the perspective view of the joined connection terminals as a­bove.
  • Fig. 5 shows a large brush and a broom mounted on handles according to the present system.
  • the version uses components in tubular sheet.
  • Axial pivot 1 with helical threaded shapes 2 are foreseen and the coaxial part 3 with counterposed threading lengths 4 and 5 emerging from the inside cylindrical wall of the above coaxial component.
