Definitions
- the present invention is directed to a length adjustable member. It will be appreciated that the member may be used in either a horizontal or vertical orientation.
- the length adjustable members find particular application as support uprights, e.g. poles and stands, for rack assemblies, being particularly, though not exclusively, suitable for merchandising display structures.
- the vertical member may have any one of a number of types of heads, such as a circular hangrail that has supporting members that fix it to the vertical member.
- the rack may include a single horizontal member or a plurality of, usually four, horizontal members that protrude from the top of the vertical member.
- a single horizontal member may extend between two vertical members.
- Display racks particularly those used for displaying clothing, are configured to a height so that the clothing garments are suspended without the bottom of the garments touching the floor and generally so that the garments are displayed at eye level.
- these same display racks can be used for garments of different lengths and other goods. It is therefore advantageous to make the vertical member adjustable.
- an adjustable vertical member for "mid- floor” display racks. These generally include an inner tube housed within an outer tube, such that the overall length of the vertical member may be adjusted by sliding the inner tube with respect to the outer tube.
- the tubes may be held at the required height by providing apertures spaced down the length of the inner and outer tubes and inserting a pin through respective apertures that line up.
- One way to lock the inner tube at the required height without additional tools or components is to provide a plurality of apertures that are spaced down the length of the outer tube.
- a retractable pin extends from the inner tube and locks into an aperture on the outer tube.
- the pin is manually pushed using a finger out of engagement with the aperture and the tubes are slid to the desired height and the pin is lined up and is biased to lock into another aperture.
- Another known system does not use pins and apertures, but has a button arrangement at the top of the inner tube.
- a length adjustable member including:
- a locking mechanism located within the inner and outer tubular members for locking the inner and outer tubular members in any of plural longitudinal positions relative to each other; wherein, upon rotation of one of the tubular members with respect to the other tubular member to a release position, the locking mechanism disengages to allow one tubular member to be slid with respect to the other to adjust the overall length of the adjustable member, and wherein, when said release position is no longer held, the locking mechanism is biased to re-engage to lock the inner and outer tubular members in one of said plural longitudinal positions.
- a length adjustable member including:
- an innermost longitudinal member fixable at its base with respect to the outer tubular member and extending within the outer tubular member, the inner tubular member being slidable between the outer tubular member and the innermost longitudinal member;
- a locking mechanism that includes a first formation, connected to either the inner tubular member or the innermost longitudinal member, for selective engagement with one of a plurality of longitudinally spaced formations on the other of the inner tubular member and the innermost longitudinal member, wherein the first formation is biased into an engaged position;
- the inner tubular member is rotatable against the bias to a release position to disengage the first formation to allow the inner tubular member to longitudinally slide with respect to the outer tubular member to adjust the overall length of the adjustable member, and wherein, when said release position is no longer held, the locking mechanism biases the first formation into engagement with a respective formation of the plurality of longitudinally spaced formations.
- the plurality of longitudinally spaced formations may include an upper and a lower surface between which the first formation engages to prevent longitudinal sliding in either direction.
- the first formation may be a lug and is preferably connected to the inner tubular member.
- the plurality of formations may be defined by a plurality of longitudinally spaced projections from the innermost longitudinal member, where the first formation engages between the surfaces of adjacent projections.
- the formations may be defined by a plurality of longitudinally space notches in the innermost longitudinal member.
- the formations are preferably of a width to allow the first formation to be rotated out of engagement by turning the inner tubular member by up to ninety degrees, or a quarter turn.
- a base from which the innermost longitudinal member extends.
- the outer tubular member may also be fixed to the base.
- the locking mechanism includes a tubular component that is attached to the inner tubular member at the end within the outer tubular member.
- the tubular component includes the first formation, or lug.
- this component may be formed as an integral assembly with the inner tubular member.
- a tubular supporting member that extends inside the inner tubular member to slidably engage the innermost longitudinal member such that the tubular supporting member is slidable longitudinally with the inner tubular member and the tubular component, and the inner tubular member and tubular component rotate relative to the innermost longitudinal member and the tubular supporting member.
- the innermost longitudinal member preferably includes a keyway and the tubular supporting member includes a corresponding longitudinal key, such that the tubular component is slidable relative to the innermost longitudinal member but does not rotate.
- the tubular supporting member is connected at its distal end to a mounting device.
- the mounting device allows an accessory, such as a horizontal arm, to be mounted to the length adjustable member.
- the base preferably includes additional mounting means to allow the adjustable member to be connected to a supporting base to hold the member upright.
- the present invention provides a length adjustable member, including:
- tubular supporting member that extends inside the tubular member and is slidably disposed about the longitudinal member
- a locking mechanism that includes a first formation, connected to either the tubular member or the longitudinal member, for selective engagement with one of a plurality of longitudinally spaced formations on the other of the tubular member and the longitudinal member, wherein the first formation is biased into an engaged position;
- tubular member is rotatable against the bias to disengage the first formation to allow the tubular member to longitudinally slide with respect to the longitudinal member to adjust the overall length of the adjustable member and wherein, upon release, the locking mechanism biases the first formation into engagement with a respective formation of the plurality of formations, and wherein the tubular supporting member slides with the tubular member but does not rotate.
- the tubular supporting member preferably includes a mounting device at its end displaced from the longitudinal member.
- the mounting device may fix a horizontal member to the length adjustable member.

- the present invention relates to a length adjustable member in the form of an upright 10 for a display stand.
- the upright has an outer tubular member or tube 12 and an inner tubular member or tube 14, both typically of steel.
- the tubes 12, 14 have respective proximal ends 16, 18 and distal ends 20, 22.
- a cantilevered arm 24 Positioned at the distal end 22 of the inner tube 14 is a cantilevered arm 24, being attached to the inner tube 14 by mounting means to be described in more detail below.
- the inner tube 14 is slidably disposed within the outer tube 12 and may be rotated to allow the inner tube 14 to slide with respect to the outer tube 12 to adjust the overall length of the upright 10.
- the arm 24 does not rotate as the inner tube 14 is rotated. This is described further below.
- a locking mechanism 28 is provided for locking the inner and outer tubes 12, 14 in a longitudinal position relative to each other.
- One part of the locking mechanism is an innermost longitudinal member or post 32 that extends upwardly from a cylindrical base segment 33, and is conveniently an aluminium extrusion.
- Base segment 33 has a central passage 35 that slidably receives post 32 and matches it in cross-section so that the post 32 cannot rotate in base segment 33.
- Post 32 is locked in base segment 33 by a transverse pin 37, and base segment 33 is in turn fixed atop a base 34 in outer tube 12 by multiple screws 39 screwed in from beneath.
- the outer tube 12 is fixed to the base 34 via radial screws (not shown).
- the post 32 extends within the outer tube 12, as best illustrated in Figure 3.
- the post 32 includes a plurality of longitudinally spaced formations 36, defined in the illustrated embodiment by multiple-spaced projections 38, to provide upper and lower engagement surfaces 40, 42.
- lug formation 30 engages between the surfaces 40, 42 to prevent relative longitudinal movement of the outer tube 12 and inner tube 14 in either direction by mechanically blocking such relative movement.
- the locking mechanism 28 further includes a tubular locking component 44 connected to the proximal end 18 of the inner tube 14.
- the inner tube 14 seats in an end rebate 45 of locking component 44, at a location determined by a matching tooth 45a and recess 45b, and the two parts are fixed together by pair of radial screws 45c.
- the outer face 44a of tubular locking component 44 is flush with the outer face of the inner tube 14, and has an annular groove 41 that seats a slightly protruding polymeric band 43 for providing a smooth sliding engagement with the inner surface of outer tube 12.
- Locking mechanism 28 further includes a hollow, flanged spigot 46 that slidably receives locking component 44 and, between component 44 and the flange 46a of spigot 46, a helical compression spring 48.
- the spring has end projections 82,83 that extend in the axial direction of the assembly and are received into matching holes 84,85 ( Figure 7) in flange 44a and tubular locking component 44.
- the bore 86 of spigot 46 has a cross-section that matches post 32 so that it is irrotationally slidable along the post.
- Tubular locking component 44 is rotatable on spigot 46 (by grasping and rotating inner tube 14) about the post against the bias of spring 48 between a locked condition, in which internal lug 30 on component 44 engages between any pair of engagement surfaces 40,42 on post 32 to mechanically block longitudinal movement of the inner tube 14 in either direction, and a release condition in which longitudinal movement is freely possible.
- the proximal end 16 of the outer tube 12 includes an annular sealing sleeve 17 to provide stability between the inner and outer tubes.
- Sleeve 17 also serves as a stop to prevent the inner tube 14 from being removed from the outer tube 12: the upper edge of the flange 46a of spigot 46 strikes the inner rim of the sealing sleeve 17 as the upright
- locking component 44 reaches its maximum length.
- the limits of rotational movement of locking component 44 are determined by interaction between an arcuate slot 87 in the component and a protruding screw- mounted grommet 88 on spigot 46.
- a tubular support 50 extends inside the inner tube 14 and is suspended from a device 66 at the top of tubular member 14.
- the support 50 is, like post 32, conveniently an aluminium extrusion, and includes a longitudinal internal key 54 that slots into a corresponding keyway 56 on post 32. This prevents the tubular support 50 from rotating with respect to the post 32 and the outer tube 12, but allows it to slide longitudinally with the inner tube 14. By providing a tolerance fit between the tubular support 50 and the post 32, the overall stability of the upright 10 is increased.
- the tubular support 50 is also shaped to fit over the projections 38.
- lug formation 30 has a shape - with a depending portion 29 - by which it drops over a side edge of a projection 38 in its locked condition, and so must be lifted a few millimetres before it can be disengaged from the projection. This is a safety feature to prevent inadvertent release of the upright simply by relative rotation of the tubes.
- the inner tube 14 To disengage the lug 30, the inner tube 14 must therefore first be lifted slightly before being rotated to rotate the locking component 44. By this action, against the return bias of spring 48, the lug 30 is rotated clear of the projections 38, and the tubes 12,14 have been relatively rotated to a release position.
- the inner tube 14 and the tubular support 50 can be slid longitudinally with respect to the outer tube 12, the post 32 and the base 34, whereby to adjust the overall length of the upright 10.
- the locking mechanism is biased by spring 48 to re-engage, so that with some sliding relative movement of tubes 12,14, lug 30 will lock in the adjacent one of the longitudinal positions defined on post 32.
- the projections 38 are of a width to allow the lug 30 to be rotated out of engagement by turning the inner tube 14 by about ninety degrees, or a quarter turn.
- the projections 38 are shaped to project at angles from the post 32 to allow ease of locking and to prevent jamming of the components.
- a mounting device 66 At the upper end of the tubular support 50 there is provided a mounting device 66, already mentioned, that provides a closed cap for the end of the support 50 and is fixed into place with screws 68.
- This sub-assembly is longitudinally fixed to inner tube 14 by means of a pair of protruding screw-mounted grommets 92 on tubular support 50
- a square nut 70 is provided that has an internally threaded shaft to receive a threaded screw 72 (shown in Figures 9a-9d).
- a cap 74 is connected to the mounting device 66 to close the distal end of the inner tube 14.
- the cap 74 is dimensioned to provide a tolerance fit between the inside diameter of the inner tube 14 and the outside diameter of the mounting device 66. O
- the cap 74 is prevented from longitudinal movement by a groove (not shown). The cap 74 is able to rotate relative to both the inner tube 14 and the mounting device 66.
- a horizontal member or arm 24 is attached to the length adjustable upright 10.
- a lower clamping section 76 includes a square aperture, which is positioned over the square nut 70, and a semi-circular surface 78. The semi-
- circular surface 78 is positioned at the appropriate right angle to allow the arm 24 to project in the required direction relative to the base 34.
- the arm 24 is positioned in the semi-circular surface 78 and includes an aperture which is lined up with the internally threaded shaft 71.
- the upper clamping section 80 is positioned on top of the arm 24, which also has an aperture. A threaded screw 72 is then used to clamp the arm 24
- the screw 72 includes a head having a diameter equal to the inner tube 14.
- the mounting device 66 and the arm 24 are connected to the tubular support 50 and not the inner tube 14. Therefore, when the inner tube 14 is rotated, the arm 24 maintains its direction with respect to the base 34.
- the height of the upright 10 can be adjusted without affecting the arm 24 and any garments hanging from it. This is particularly advantageous when an arm 24 extends between two uprights 10 to provide a clothes rack.
- the height of the two uprights 10 can be adjusted simultaneously, one with each hand, whilst the arm 24 extends between the two of them.
- the display stand system illustrated in Figures 1 to 9 is an elegant and aesthetically pleasing product in which the length adjustability is provided without any visual and physical interruptions to the continuity of the upright. Moreover, the adjustability feature does not rely on any button arrangement at the top of the upright, meaning that in this area there is no restriction of the form or arrangement of mounting accessories: maximum flexibility in this respect is available. Notwithstanding 5 the lack of external physical manifestations, such as apertures, pins or buttons, the lock within is a mechanical lock and not merely reliant on a fictional hold, which would place undesirable load limits on the structure and give rise to long term wear problems.
- FIG. 10 to 15 A second embodiment of the invention is illustrated in Figures 10 to 15. This embodiment is a floor-to-ceiling tension mounted pole system 100. Corresponding I O parts relative to the embodiment of Figures 1 to 9 are indicated by like reference numerals preceded by a 1. Common features will not be restated, but modified and additional aspects will now be described.
- the inner tube is not required to mount accessories such as cantilevered arms at its upper end but instead engages a ceiling, there is no requirement for an irrotational
- the upper end of inner tube 114 has a fitting 210 with a collar component 212 fixed into 5 the end of the tube and a freely rotatable end disk 214 joumalled in a bearing piece 215 so that when the disk strikes a ceiling surface during adjustment of the post inner tube 114 can continue to be rotated (e.g. to allow it to return to the locked condition) relative to the now stationary disk in contact with the ceiling.
- the other additional feature of the second embodiment is the arrangement of base assembly 215 by which the pole can be tensioned and clamped into position once adjusted, by the mechanism according to the invention, approximately to the correct position.
- Coupler component 220 is normally latched against rotation within casing 230 by a finger releasable button 240 pivotally mounted on base 134. This button is biased by spring 248 into one of a number of vertically extending flutes 228 in the threaded lower portion of coupler component 220 (the condition shown in Figure 14a).
- threads 225 on coupler component 220 and diecast casing 230 are arranged such that, once inner tube 114 has been rotated in one direction, e.g. anti- clockwise, to disengage the lug 130 from the projections 138 on post 132, the inner tube can be raised, while maintaining the rotation against spring 148, to extend the pole to the ceiling.
- button 240 is now held down ( Figure 15a) and the inner tube 112 released back to the locking condition and then rotated further in that other direction (e.g. clockwise), coupler component 220 will rotate and thereby adjust its length relative to casing 230 ( Figure 15b), whereby to tension and clamp the pole in position.
- the position is maintained by releasing the button 250 to reengage flutes 228: some slight rotational adjustment of the pole may be necessary until the button pops out upon engagement with a flute 228.
- an elegant and aesthetically pleasing pole assembly has been provided that is easily adjustable and mechanically locked without visible apertures, pins or buttons along the length of the pole.
- the pole can be readily put to whatever use is required in an overall merchandising display system.
