Definitions

  • the field of the invention relates to a cleaning tool, and in particular the handle of a telescopic cleaning tool.
  • the handle plays a fundamental role. Depending on the intended use of the tool placed on the end of the handle, the handle itself must meet predetermined requirements of strength, lightness, flexibility, etc.
  • One of the essential characteristics for some types of tools is the length. This characteristic is crucial for the tool to be used comfortably since the distance between the handle and the tool needs to take into account the height of the operator. A length that is too long or shorter than expected can make the various cleaning operations particularly uncomfortable for the operator. Considering that the operator is a professional, this aspect, namely that the handle is the right length, it is very important.
  • the telescopic handle has been used for some time to meet the above-mentioned requirements, which makes it possible to obtain a handle of the desired length by fixing two tubes together, one inside the other.
  • the handles need to be adjusted to the desired length. This is not particularly difficult to achieve, since all you have to do is release the relative fastening device between the two handles, extend or shorten the relative connection between the two tubular sections, and then fix them together again.
  • connection element that allows the two tubular sections to be fixed to each other to obtain the desired length of the handle, is composed of several parts that can be detached if the inner tube is completely removed from the outer tube.
  • some tubes also have an additional part to prevent the two tubes from being able to slide off each other, though this adds additional complexity to the whole. Moreover, these parts over time tend to become less efficient, prone to breaking or stick to the walls of the tubes, or else failing to function correctly. In the aforementioned situations, the handle is unusable and must be replaced.
  • connection elements do not tolerate dirt, humidity, water and/or detergents, and in such conditions they could possibly seize up or not work at all.
  • the object of the present invention is to make available a telescopic handle with an extremely simplified anti-slip device, which prevents its decoupling.
  • a further object of the present invention is to make available a telescopic handle with a durable, efficient and reliable anti-slip device.
  • a different object of the present invention is to make available a telescopic handle with an anti-slip device that is easy to make.
  • An important object of the present invention is to make available a telescopic handle with an anti-slip device that is affordable and inexpensive
  • An important object of the present invention is to make available a telescopic handle with an anti-slip device that does not have parts that could break, get worn or get lost.
  • An equally important object of this invention is to make available a telescopic handle with an anti-slip device that maintains the correct orientation of the tool with respect to the handle.
  • Another object of the present invention is to make available a telescopic handle with an anti-slip device that is requires no maintenance.
  • a telescopic handle with an anti-slip device that is composed of two tubular segments with an ⁇ extl outer diameter of a first segment that is smaller ⁇ than the int2 inner diameter of a second tubular segment, so the first can slide within the tubular cavity of the second, including a spaced series of two or more holes distributed along the longitudinal extension of the second segment and also with an elastic device for engaging said holes near the end of the first segment and which slides entirely to the second segment, where there is at least one circumferential expansion of the end section of the first ⁇ extl ⁇ int2 ⁇ segment, and where there is a collar insert or a taper of the tubular segment near the end section of the second segment, whose internal dimensions ⁇ int > extl collar ⁇ are greater than the diameter of the first tubular segment but interfere ⁇ int ⁇ ⁇ extl with said expansion preventing from crossing and subsequently disconnecting, by the detachment of the telescopic connection between the
  • the handle is placed at a top end of a tubular segment in a fixed manner.
  • the series of holes extends along the longitudinal extension on two quadrature that are perpendicular to one another.
  • said collar is made of Teflon or a similar wear-resistant material.
  • said collar has a profile that goes around the entire circumference of the segment of internal telescoped tube.
  • a second expansion of the inner tube similar to that of the end that prevents the collar from being surpassed, and spaced apart from the first expansion prevents or limits an oscillation or pitching of the free end of the first tube inserted in the second tube.
  • the cleaning tool 5 includes a telescopic handle 6.
  • a cleaning accessory 3 is joined to the lower end of said telescopic handle 6.
  • a grip 4 is connected to the upper end of said telescopic handle 6.
  • Said telescopic handle 6 includes at least two tubular segments 1, 2 which, when inserted one inside the other, can be fixed to each other for a certain portion, determining the extended length of said telescopic handle 6.
  • an anti-slip device 11 which is extremely simple to use, very safe to operate and has also proven to be reliable.
  • connection between said collar 10 and the permanent circumferential expansion 9 prevents a pitch of the tube with the smaller diameter 1 with respect to the tube with the larger diameter 2.
  • a second series of holes 13 is provided in quadrature with respect to the first series of holes 7 provided on the perimeter surface of the larger diameter tubular 2.
  • the elastic engagement 8 can be connected to the first 7 or the second 13 series of holes, it is possible to maintain the handle 4 for each desired length extension of the telescopic handle 6 at a first position or at a second position, in quadrature with the first, depending on the operator's preferences.
