Definitions

  • the present invention concerns a device for the quick blocking and release of tubolar handles consisting in at least two rods or sectional portions that can be engaged one with the other, particularly concerning broom handles, brush handles and generally handles for manual use equipment of any kind.
  • said handles are actually devided in a plurality of portions that can be assembled when the rod is to be used due to the engagement of one portion with the other.
  • said engagements that are of the telescopic-friction, screw and joint kind, don't allow a safe and lasting blocking of the portions during the use, due to the considerable torsional stress said portions undergo.
  • Said aims are reached by means of the device, according to the present invention, for quick blocking and releasing of tubolar handles realized in at least two engageable rods, the first rod having the engaging end of a diameter partially reduced for engagement in the second rod, characterized in that an insert is bound axially and rotatory to said end with reduced diameter, said insert showing an axial extension provided with a tapered truncated-cone shaped portion, outwardly threaded, onto which an expansible bush may be screwed, said bush having a truncated-cone shaped part engaged with said insert portion and the outer surface able to adhere to the inner wall of the second rod so as to rotatory engage with the same for determining, with the rotation of the first rod and the screwing of the bush, the consequent expansion due to the widening action performed by the conical portion against the inner truncated-cone shaped part of the bush, and the consequent blocking of the rods.
  • the device according to the present invention for the quick blocking and releasing of tubolar handles out of at least two portions or rods A and B, preferably hollow and engageable, is generally shown.
  • Rod A shows the engaging end 1 having, for a part, a reduced diameter for the engagement with rod B.
  • the device comprises an insert 2 showing a cylindrical portion 3 that can be forced into end 1 of rod 1 for being axially and rotatory bound therein by means of punchings 4; portion 3 widens with a set-back 5 that acts as a rest against the opening of end 1.
  • Portion 3 shown an axial outward extension to rod A, in which a portion 6, truncated-cone shaped and tapered, is defined, outwardly showing a threading 7; portion 6 further extends in a peg 8 structure A, ending in a tablet 12 of greater dimensions; insert 2 is advantageously realized out of one single piece by pressing of material of the kind of plastic.
  • a bush 10 is mounted, outwardly showing a cylindrical surface for rotatory engagement against the inner surface of rod B, ending in a short conical part 11 for facilitating the engagement in said rod B; the bush 10 inwardly shows a truncated-cone shaped and threaded part 12; the bush shows a fissure 13 that cuts all the length thereof, due to the material out of which the bush is realized and that is preferably of the plastic kind, the widening of said bush.
  • the bush remains substantially adherent to rod B due to the friction of the materials and that keeping up the screwing said adherence increases together with the deformation of the bush; it should also be noted that the greater the effort for screwing the parts, the greater the torsional seal of the coupling - that means: if during the use of the handle the rods will be solicited one with respect to the other torsionally in the sense of release, it will be sufficient - for avoiding the release - to screw the rods stronger at the time of assembling.
  • the handle may be realized in any number of parts and any diameter of the rods and of the device.
