Definitions

  • This invention relates to a locking arrangement for telescopically moving tubes, and in particular to an assembly for a locking arrangement, and to formations used on the telescopic tubes.
  • This invention will find many applications in respect of telescopic tubes which need to be moved from one locked position to another. Examples of applications include telescopic wands used with vacuum cleaning machines, tripod legs, or any other form of adjustable structure or support.
  • Common locking arrangements between an inner and outer tube normally comprise a series of spaced indentations or recesses along a portion of the surface of the inner tube with a fitting secured to the outer tube that has an element that locates within the recess. When this element is physically held within the recess, the two tubes are locked with respect to one another.
  • the fitting normally comprises a manually operated slide, which when pushed to a certain position, enables the element to lift clear of the recesses. This then allows the inner tube to slide with respect to the outer tube.
  • the manually operated slide is spring-loaded, and will return to its locked position when released.
  • the recesses on the inner tube normally comprise a short channel formed into the surface of the inner tube with the longitudinal axis of the channel at right angles with respect to the longitudinal axis of the inner tube.
  • Both the inner .and outer tube are normally made of either light gauge stainless steel, aluminium, or any other suitable material and the indentations can simply be pressed into the surface of the inner tube.
  • a common problem with existing locking arrangements is the extremely complex nature of the fitting. Several components are used both on the inner and outer surface of the outer tube in order to fix the fitting in place, and numerous other components are used to assemble the manually operated slide.
  • the locking mechanism fails as a result of the excessive force applied by the element within the recess flattening the surface of the inner tube between adjacent recesses thereby allowing movement of the inner tube with respect to the outer tube.
  • the side walls of the channels forming the indentation are normally inclined away from the vertical, and therefore generally have very little resistance to compressive loading.
  • the locking arrangements need to be rigid and therefore robust to prevent flexing under load which allows lifting of the element and which in turn leads to flattening of the recesses.
  • the invention is a telescopic tubular assembly including: an outer tube, a collar located at one end of said outer tube, a slider mount on said collar that projects substantially radially away from said collar, a slider engaged on said slider mount so that it is able to slide along said slider mount, abutment means at each end of said slider mount to limit movement of said slider, an inner tube located within said outer tube, and through said collar, for telescopic movement with respect to said outer tube, and locking means acting between said collar and said inner tube to hold said inner tube with respect to said outer tube, said locking means being operated by said slider to both disengage said locking means to thereby allow relative movement of said inner and outer tubes and to re-engage said locking means.
  • the inner and outer tubes may be made from light gauge stainless steel, aluminium or any other suitable material including a moulded plastic.
  • the outer tube may have a cut-out at one end so that the slider mount on the collar can be positioned so that it extends through that cut-out.
  • the arrangement of the cut-out and of the slider mount which fits into the cut-out is such that the slider is held in position when the collar is located in the outer tube.
  • the slider may be arranged to engage a portion of the outer tube such as an end of the cut-out portion so that its movement is limited in that particular direction.
  • the collar may be provided with abutment surfaces which limit the movement of the slider in that direction.
  • the slider mount may be provided with longitudinal recesses or track surfaces, and the slider may be provided with inwardly directed longitudinal flanges which locate within the longitudinal recesses or track surfaces. This holds the slider onto the slider mount as well as allowing the slider to move on the slider mount.
  • the slider mount comprises an elongate projection parallel to the longitudinal axis of the inner and outer tubes and the cut-out is correspondingly shaped to receive the projection.
  • the cut-out is open at one end and enables the outer tube and collar to be pushed together.
  • the cut-out portion may have inwardly projecting barbs which locate within corresponding recesses within the slider projection.
  • the resilient nature of the outer tube enables the cut-out to spring slightly open so that the barbs locate within the recesses. Once in position, the collar is held with respect to the outer tube.
  • Additional fixing means may also be provided comprising inwardly directed tabs which locate in corresponding recesses within the collar. These tabs and recesses may be evenly spaced around the diameter of the outer tube to prevent rocking of the collar within the outer tube due to the application of asymmetric forces.
  • the inner tube is provided with a series of spaced recesses comprising channels which are formed across the tube at 90° to its longitudinal axis.
  • a locking element comprising a cylinder or roller is preferably used to engage the recess.
  • the slider track has an aperture within which the roller moves into and out of engagement with each of the recesses.
  • the slider is provided with an abutment surface which holds the roller within the recess and prevents vertical movement thereby locking the two tubes together. It also has a recess that can be positioned over the aperture to allow vertical movement of the roller. When in this position, if force is applied to the inner tube, then the roller element is moved vertically so that it is fully clear of the recess. This then enables the inner tube to move with respect to the outer tube and when the desired relative position is obtained, by releasing the slider element, the roller is then able to drop into the next recess which aligns with the aperture.
  • the slider is spring-loaded so that when it is released, the slider moves back to a position where the abutment surface is located over the roller and aperture.
  • the slider projection may incorporate a resilient finger held at one end with respect to the slider projection. The free end may have a projection equivalent to the roller. The slider controls locking movement of the projection in a manner similar to the roller.
  • the inner tube is preferably designed so that it is unable to rotate with respect to the outer tube.
  • One way to achieve this is to form a pair of spaced channels into the surface of the inner tube.
  • the channels are parallel to the longitudinal axis of the inner tube and may extend along most of its length.
  • Elongate projections may be formed on the internal surface of the collar that respectively locate within the channels so that rotation is prevented.
  • the channels ate formed within the surface of a tubul.ar member having a circular cross-section.
  • the tubular member may be a light gauge stainless steel, aluminium or other suitable material including a moulded plastic.
  • the channels may be formed by any appropriate means including a pressing operation, a roll-forming operation or a combination of both.
  • the elongate channels have an axis that is substantially parallel to the longitudinal axis of the inner tube, and which may be spaced by a distance which equals the width of the plurality of recesses into which the locking element may locate. The pressing of the channels into the outer surface of the inner tube results in the formation of the two spaced generally radial walls, with the remaining surface of the inner tube between the two channels forming the intermediate wall.
  • recesses may then be formed across the surface of the intermediate wall so that the recesses are formed both in the intermediate wall and the two side w.alls.
  • the advantage of this configuration is that, when compressive forces are applied to the assembly, the locking element will apply load in the recess which is resisted by the radially positioned walls.
  • the configuration of the locking formation, and in particular the spaced radially positioned walls within which the recesses are formed, has significantly increased load bearing capacity by comparison to prior art recesses which are simply channels formed within the outer surface of a tube having a circular cross-section. This in turn means that other components can be constructed more lightly with simpler assembly as a result of the recesses having an improved load bearing capacity.
  • the intermediate wall extending between the radially positioned walls may be flattened or comprised of substantially planar section.
  • the inner tube may have projections formed in the end of the inner tube that locates within the outer tube that abut against the collar thereby preventing the inner tube disengaging from the collar and outer tube.

  • the inner tube 10 is designed to telescopically slide within the outer tube 11.
  • the inner and outer tubes 10 and 11 are manufactured from light gauge stainless steel.
  • the inner tube 10 has a pair of spaced channels 12 formed along its length.
  • the channels 12 comprise a pair of spaced and generally radial side walls 13 with an intermediate wall 14 extending between the side walls 13.
  • a plurality of recesses 15 are formed along the intermediate wall 14. The recesses 15 also extend across the side walls 13.
  • the channels 12 are formed in the inner tube 10 which starts as a tube having circular cross-section.
  • the channels 12 are formed by a pressing operation.
  • the channels 12 have a right-angled cross-section with one of the surfaces of the channel comprising a side wall 13.
  • the channels 12 can be formed either by a drawing or roll forming.
  • the recesses 15 can be formed in the same manufacturing operation.
  • the process of forming the channels 12 within the outer surface of the inner tube 10 result in the intermediate wall 14 maintaining the curved cross-section of the inner tube 10.
  • the intermediate wall 14 may be flattened to remove this curvature to enhance the strength of the recesses 15 to prevent deformation when compressive load is applied to the assembled tubes 10 and 11.
  • Fig 5 shows a plunger 17 which is located in the end of the inner tube 10 that locates within the outer tube 11.
  • the plunger 17 is shown in position on the end of the inner tube 10 in Fig 1.
  • the end of the plunger has a flexible wall 18 which forms an air-tight seal between the inner and outer tubes 10 and 11.
  • Fig 7 shows the cut-out 20 that is formed into the end of the outer tube 11.
  • the cutout 20 has a pair of barbs 21 and recesses 22 which are used for fixing purposes.
  • Figs 4 and 6 show best the collar 24.
  • the collar has a tubular body 46 that is fixed within the enlarged end 47 of the outer tube 11.
  • Tabs 19 are pressed inwardly from the outer tube 11 and locate in recesses 23 to assist in locking the collar 24 to the outer tube 11.
  • the inner diameter of the collar 24 is shaped to allow the inner tube 10 to be positioned within the collar and to slide relative thereto.
  • the internal surface 25 of the collar 24 has a pair of elongate projections 27 that locate within channels 12. This prevents rotation of the inner tube 10 with respect to the collar 24.
  • the collar 24 has a slider mount 29 that projects from the tubular body of the collar 24.
  • the slider mount 29 has longitudinal recesses that comprise channels 30 on either side of the slider mount 29.
  • the slider mount 29 also has channels 31 on either side of the slider mount 29.
  • At the end of the channels 31 there is a recess 32 and a projection 33 that are designed to be engaged by the barbs 21 and recesses 22 of the outer tube 11.
  • the collar 24 is preferably first positioned over the inner tube 10.
  • the end of the inner tube 10 is provided with a series of projections 48 (see Fig 5) formed in the peripheral edge of the end of the inner tube 10 which will abut against the collar 24, thereby preventing the inner tube 10 completely withdrawing from the assembly once the collar 24 is in position.
  • the ends of the channels 12, which when formed extend to the end of the inner tube 10, may have a small section 49 of each channel at the end of the inner tube 10 pressed back to its original position to thereby form projections against which the collar 24 will abut.
  • the slider 35 illustrated in Figs 1, 2 and 3 is positioned on the slider mount 29 before the collar 24 is finally secured to the outer tube 11.
  • the slider 35 has a pair of longitudinal flanges 36 which locate within the channels 30.
  • the slider also has a central body 37 that locates within slot 38 in the collar 24.
  • the slider body 37 has a recess 39 within which a spring 34 locates. It also has an abutment surface 40 and a recess 41.
  • the slider mount 29 has an aperture 42 within which a roller 50 locates.
  • the aperture 42 within which a roller 50 locates.
  • the roller 50 in this embodiment is a cylindrical shape having a diameter of approximately 4 mm and a length of approximately 10 mm.
  • the roller 50 is designed to locate within recesses 15 on the inner tube 10.
  • the aperture 42 in the slider mount 29 is provided with side channels
  • the abutment surface 40 is normally positioned over the aperture 42. In this position, the roller 50 is unable to move vertically, and is held in position within the recesses 15. This effectively then locks the inner tube 10 with respect to the collar 24.
  • the recess 41 can be brought into alignment over the aperture 42 to thereby enable vertical movement of the roller 50. This then allows the roller 50 to lift sufficiently to clear the recesses 15 thereby allowing movement of the inner tube 10 with respect to the collar 24.
  • the collar 24 is pushed into the outer tube 11.
  • the slider 35 is prevented from disengaging from the slider mount 29 as a result of abutment of the ledge -44 against the outer tube 11 at the end of the cut-out 20.
  • the end of the slot 38 is a wall 51 that restrains the slider 35 at that end of the slider mount 29.
  • the slider 35 In use, the slider 35 is pushed forward so that the recess 41 aligns with the aperture 42. This enables the roller 50 to raise vertically so that it is clear of the recesses 15. The recesses 15 will tend to force the roller 50 vertically thereby enabling the inner tube 10 to move with respect to the outer tube. Provided that the slider 35 remains depressed in a forward position, then the roller 50 will pass over the recesses 15. When the slider 35 is released, the roller 50 will engage the next recess 15 that aligns with the aperture 42 thereby allowing the slider to move to its rearmost position with the abutment surface 40 located over the aperture 42. In this position, the roller 50 then locks the inner tube 10 from any further movement.
  • the channels 12 formed from the side walls and intermediate wall 13 and 14 will provide increased rigidity when compressive loading is applied to the inner tube 10.
  • the slider mount 29 may incorporate a resilient finger (not drawn) held at one end by the slider mount 29 with the free end comprising a projection that locates within the recesses 15.
  • the slider 35 may be adapted to work in a similar manner as it does with respect to the roller 50. That is, an abutment surface may be provided to hold the finger against vertical movement so that the projection locks within the recess 15, and in a second position the finger may be allowed sufficient vertical movement so that the inner tube 10 can move with respect to the outer tube 11.
  • the locking formation comprises only a small number of components and is quickly and easily assembled. The invention has specific application to use with vacuum cleaner extension tubes, but will obviously have other applications.
