Definitions

  • a typical bi-folding door includes a plurality of planar panels connected to each other at their edges so as to be foldable between a configuration in which the panels align in a common plane to close an opening, and a second configuration in which the panels are stacked at one side of the opening .
  • Selected ones of the hinges connecting the panels respectively include a wheeled bogey which runs along a horizontal track above the opening. The door panels are thus supported by the track.
  • the hinges should be adjustable so that the position of the hinge leaves (and in turn the door panel(s) attached thereto) can be adjusted relative to the track to accommodate errors in the shape and alignment of the panels and/or the opening during manufacture and installation.
  • the hinge leaves bear on a stop at the lower end of the hinge pin, and the upper end of the hinge pin is threaded into the bogey.
  • the hinge may be adjusted.
  • a locking nut is also carried by the threaded end of the hinge pin and, once the hinge is satisfactorily adjusted, tightened against the bogey to lock the mechanism so that the adjusted position does not change over time.
  • the present inventors consider this hinge to be difficult to install. To initiate the threaded engagement one must carefully align and support the door panels. There is a significant risk of cross -threading.
  • the locking nut is considered to be fiddly in that it is mounted in the crowded space at the upper end of the pin adjacent to the bogey.
  • the locking nut is replaced by a locking collar irrotationally coupled to the hinge pin via a flat on the pin and a complementary form on the inside of the collar.
  • the collar is movable to engage the bogey at selected rotational orientations.
  • the collar is moved along the hinge pin so as to disengage the bogey.
  • the pin can then be screwed or unscrewed from the bogey to adjust the hinge.
  • the collar is moved back into contact with the collar.
  • the pin may then be rotated a fraction of a turn in either direction before the collar reaches one of the selected orientations and engages the bogey to prevent further rotation of the hinge pin.
  • the inventors consider this arrangement to be fiddly and to result in less than ideal adjustment of the hinge in that the fraction of a turn before the locking collar engages the bogey necessarily involves some movement away from the ideal adjusted position.
  • the hinge pin is threadingly engaged with the bogey and a locking mechanism locks the hinge pin to one of the hinge leaves at one of a plurality of discrete locking positions.
  • a locking mechanism locks the hinge pin to one of the hinge leaves at one of a plurality of discrete locking positions.
  • each pivot mount includes a mounting member which is fixed to the fixed door frame and carries a respective slide block which in turn carries a respective hinge pin.
  • a threaded member is connected between the mounting member and slide block of each pivot mount to permit screw adjustment of the pivot axis.
  • This approach requires accessing the horizontally directed head of the threaded member with a screwdriver which is fiddley in the crowded areas above and below the door panels. Moreover several turns of the screwdriver may be required to achieve suitable adjustment.
  • connection arrangement including a first part; a second part; and a member movable, relative to the first part, from a first position to a second position; wherein one of the first part and the second part defines a cavity; when the member is in its first position, a portion of the other of the first part and the second part is receivable within the cavity; and in its second position the member blocks retraction of one or more features or portions, of or carried by the first part, positioned to engage the second part to resist removal of the portion of the other of the first part and the second part from the cavity.
  • the member and the one or more features or portions of the first part are arranged to co-operate such that movement of the member from its first position to its second position drives the one or more features or portions of the first part to so engage the second part.
  • the first part may include a tubular portion internally carrying the member.

  • the member and the further member are arranged to flex so as to disengage in response to an insertion force exceeding a threshold, e.g. the further member may be at least partly receivable within the member and include a cavity to permit said flexing.
  • a pivot including the connection arrangement, in which case the first part may be a pivot pin, and the second part may be a bogey.
  • the pivot may further include an element threadingly engaged with the pivot pin and rotatable to drive one or more members along the pivot pin to adjust the pivot; and a spacer arranged to space the element from the members; wherein the spacer and the pivot pin include features co-operable to prevent rotation of the spacer relative to the pivot pin so as to shield the element from rotation of the members about the pivot pin.
  • a pivot including a first part; a second part; and a member movable, relative to the first part, from a first position to a second position; wherein the first part is a pivot pin; the second part defines a cavity; when the member is in its first position, a portion of the first part is receivable within the cavity; and in its second position the member blocks retraction of one or more features or portions, of or carried by the first part, positioned to engage the second part to resist removal of the receivable portion of the first part from the cavity.
  • Another aspect of the invention provides a mechanism including structure; an element rotatable, relative to the structure, about an axis to axially drive one or more members; and a spacer arranged to space the element from the members; wherein the spacer and the structure include features co-operable to prevent rotation of the spacer relative to the structure to shield the element from movement of the members.
  • the element is threadingly engaged with the structure.
  • the co-operable features may include a flat of the structure.
  • a stop is arranged to prevent the element being fully disengaged from the structure.
  • the stop may be threadingly engaged with the structure, in which case threading engagement of the stop is preferably opposite-handed to an or the threading engagement of the element with the structure.
  • the members are preferably mounted so as to pivot relative to the structure, e.g. the structure may be a pin about which the members pivot.
  • a mechanism for pivotally supporting a panel, including structure about which the panel may pivot; an element rotatable, relative to the structure, about an axis to axially drive the panel; and a washer arranged to space the element from the panel; wherein the washer and the structure include features co-operable to prevent rotation of the spacer relative to the structure to shield the element from movement of the panel.

  • the locking member 4 is detailed in figures 4a to 4c.
  • the locking member 4 takes the form of an upright cylindrical tubular body turned from stainless steel.
  • An upper end of the locking member 4 carries a conical chamfer 4a about its outer periphery.

  • connection arrangement 1 1 The operation of the connection arrangement 1 1 will now be described.
  • the pin assembly 10 is connected to the bogey 20 by inserting the pin assembly 10 into the cavity 20c. In doing so the pin assembly 10 is moved in its axial direction. As the pin assembly 10 is so advanced, the insertion pin 6 strikes a stop within the bogey 20. Within the described hinge the axle 20e functions as the stop.
  • FIG. 9b illustrates the pin assembly 10 and the bogey 20 after an initial portion of the insertion in which the locking member 4 so moves against the bias of the spring 5. It will be appreciated that during this initial phase of insertion the insertion pin 6 serves to space the locking member 4 from the cavity 20c.
  • the pin 9 butts the lower end of the slot 1 c such that a load path uninterrupted by the spring 5 is defined between the pin body 1 and the insertion pin 6. Additional force applied to the pin body 1 acts on insertion pin 6, and in particular the lower inclined face of its rib 6b, via the locking member 4. The inclined face of the rib 6b and the inclined lead-in into the region 4c co-operate to inwardly drive the exterior of the pin 6.
  • the slot 6c permits the necessary portions of the pin 6 to flex inwardly whereby the pin 6, and in particular its rib 6b, can slide through the portion 4c of the locking member 4.
  • the described clip mechanism results in the locking member 4 and the insertion pin 6 disengaging when the force applied to push the pin assembly 10 into the bogey 20 exceeds a predetermined threshold value.
  • a predetermined threshold value is in a range to suit manipulation by hand without any inadvertent disengagement.
  • the locking member 4 is formed of stainless steel and is thus strong and rigid enough to support the elements 8 in and of itself.
  • the locking member 4 might be formed of more flexible materials in which case the locking member 4 may bear against the solid (i.e. not slotted) portion of the pin 6 whilst serving to support the bearings 8.
  • the grooves 1d receive the projections 20g and serve to prevent rotation of the pin body 1 relative to the bogey 20.
  • a tool is inserted into the pin 9 to move the pin downwardly to allow the bearings 8 to retract.
  • connection arrangement 11 includes a first part in the form of pin body 1 .
  • An end portion of the pin body 1 is received within a cavity 20C of a second part in the form of bogey 20.
  • connection arrangement 1 1 has been described.
  • Other variants of the connection arrangement are possible.
  • Engagement features in the form of discrete elements as in the bearings 8 could be replaced with portions integral to the pin body 1 .
  • the engagement features may be outwardly-biased such that the locking member 4 need not outwardly drive these locking features.
  • the adjustment mechanism 12 includes an externally threaded lower end 1 e of the pin body 1 , adjusting nut 2, locking washer 3 and limit screw 7.
  • the threaded lower end 1 e has a machined flat along its length 1f and a central threaded bore 1 g in its end face.
  • the external thread on the threaded lower end 1 e and the internal thread of the bore 1g are "opposite-handed". In this embodiment the external thread is right-handed and the internal thread is left-handed.
  • the spacer 3 takes the form of a locking washer having a central circular opening truncated by a flat portion 3a.
  • the adjusting nut 2 consists of a tubular body.
  • the central passage of the tubular body terminates at one end 2c with an internal thread complementary to the external thread of the portion 1 e, and at the other end with a tool -receiving socket 2a.
  • the tool-receiving socket is a 10 millimetre Allen key fitting.
  • a central portion 2b of the internal passage is threadless and dimensioned so as not to interfere with the threads of the portion 1 e.
  • the nut is preferably formed of stainless steel and most preferably machined from raw material, e.g. machined from bar stock as opposed to cast material. Formation from cast material leads to generally inferior strength characteristics.
  • Limit screw 7 is threadingly engageable with the bore 1g.
  • Figures 9a to 9c illustrates the adjustment mechanism 12.
  • the spacer 3 is first fitted to the threaded portion 1 e such that its flat 3a engages the flat 1f to prevent rotation of the spacer 3 relative to the pin body 1 .
  • the adjustment screw 2 is threadingly engaged with the thread portion 1 e before the limit screw is engaged with the bore
  • one or more hinge leaves (not shown) (or more specifically the knuckles of the hinge leaves) embrace the pin body 1 and bear against the spacer 3.
  • a tool insertable within the tool-receiving bore 2a is used to screw or unscrew the adjustment nut 2 to adjust the vertical position of the hinge leaves (and in turn the door or window panels carried thereby) relative to the pin body 1 (and in turn relative to the track); i.e. the nut 2 is rotated about the axis of the pin body 1 to drive the hinge leaves along the axis of the pin body 1.
  • the hinge leaves pivot about the pin body 1 they bear against the spacer 3 which is fixed relative to the pin so that the rotational motion of the hinge leaves is not transmitted to the adjustment nut 2.
  • the adjustment nut 2 is shielded from this rotational motion and can thus maintain a selected alignment in operation.
  • the limit screw 7a includes a disc-like head portion 7a having a diameter selected to interfere with the female threads of the portion 2c whereby the screw 7 defines a limit of adjustment and prevents the adjusting nut 2 being unscrewed beyond this point.
  • the opposite-handing of portions 1 e, 1 g prevents nut 2 and screw 7 rotating together. Accordingly the adjusting nut (and the spacer, and hinge leaves and door carried thereby) cannot be inadvertently unscrewed off the end of the pin 1 b.
  • the height of the hinge leaves is infinitely adjustable (within a permissible range of adjustment determined by the length of the threaded portion 1 e) such that an ideal adjustment position can be selected and maintained in use.
  • Another advantage of the described preferred form of hinge is in that adjustment is effected without having to access the crowded, fiddly, region adjacent the bogey.
  • the simplicity of the described adjustment mechanism is one of its key advantages.
  • the simplicity of the mechanism is such that it may be supplied in a kit of unassembled, or partially assembled, parts for assembly by a customer.

  • the boss 34b is externally threaded and includes a tool receiving recess, in the form of Allen key socket 34c, formed in its end face.
  • a spigot 34d projects normally from the other major face of the disk 34a.
  • the spigot 34d is cylindrical having a diameter about 1/3 that of the disk 34a and sits in tangential alignment with a periphery of the disk 34a.
  • the spigot 34d is thus eccentric to the disk 34a; i.e.
  • the spigot 34d is offset from the common axis of the disk 34a and the spigot 34b.
  • the cam 34 is dimensioned for its boss 34b to project downwardly through the aperture 39f whilst the disk 34a nests within the recess defined by the structure 39h such that the cam 34 is rotatably mounted in the member 39.
  • the spigot 34d describes an arc about the axis of the aperture 39f.
  • the nut 40 (see Figure 10) has a hexagonal outer profile to be gripped by a spanner and a threaded internal bore co-operable with the spigot 34b. The nut is engaged with a portion of the spigot 34b projecting downwardly from the mounting member 39 so that the cam 34 is retained relative to the mounting member 39.
  • Nuts 31 , 37 are alike. They each consist of a simple square plate of material having a threaded through bore passing centrally through its major faces.
  • the spring 38 is detailed in Figures 16a to 16b.
  • the spring 38 includes a vertical front web 38a which is gently curved in profile.
  • An arm 38b projects horizontally from the concave side of the web 38a and includes a vertical downward return.
  • a bore 38c passes horizontally through the web 38a and return of arm 38b.
  • the spring 16 is dimensioned so that its arm 38b snugly embraces an upper edge of the nut 37 and its bore 38c aligns with the bore of the nut 37.
  • the nut 37 and spring 38 are together received within the pocket 39d so that the curved web 38a is compressed between upper and lower portions of the nut 37 and at its midpoint an outer wall of the pocket 39d. This compression creates a degree of interference whereby the nut 37 does not readily fall out of the pocket 39d.
  • the nut 37 defines a threaded portion of the first unit 34, 37, 38, 39, 40.
  • the nut 31 is snugly received within the pocket 32a. Its internal bore defines a threaded portion of the second unit 31 , 32, 33, 35.
  • the sleeve 35 is a short upright tubular structure having a circular cross -section. Its upper edge is bifurcated by a pair of upwardly opened aligned grooves 35a. A lower end of the sleeve 35 is surrounded by a short radial flange 35b. The flange 35b is truncated at a chord to define a flat 35c.
  • the sleeve 35 is received within and mates with the socket 32c so that the tabs 32d are received within the grooves 35a to prevent rotation of the sleeve 35 relative to the slide member 32.
  • the sleeve 35 and the member 32 together define a cavity equivalent to the cavity 20c, including an inwardly open sub-cavity encircling the interior of the sleeve 35, for carrying a pivot pin.
  • a sub-assembly including the slide block 32, nut 31 and collar 35 is received within the walls of the mounting member 39.
  • Pin 33 is inserted via grooves 39e into the bore 32f to complete the second unit 31 , 32, 33 and 35. Free ends of the pin 33 project outwardly beyond the sides of the member 32 to engage and run along respective ones of the grooves 39e.
  • the long walls of the member 39 co-operate with the corresponding walls of the member 32, and the pin 33 (or more specifically its free ends) co-operate with the slots 39e to prevent rotation of the second unit relative to the first unit.
  • the pivot mount 30 is mounted to a top track of a bi-folding door via the mounting features 39i, 39j, 39k and a mounting plate (not shown).
  • the subsequent adjustment steps will now be described with reference to Figures 1 1 a to 12c.
  • the spigot 34d is received within and sized to slide along the groove 32e.
  • the threaded member 36 is disengaged from the threaded portion of the second unit defined by the nut 31 .
  • the threaded member 36 is engaged with the threaded portion of the first unit defined by the nut 37, although this is not essential.
  • an Allen key inserted into the socket 34c may be used to rotationally drive the cam 34 so that its spigot 34d acts on the groove 32e to drive the second unit along the first unit.
  • the distance between the first unit and the second unit can thus be adjusted.
  • a quarter turn of the Allen key corresponds to an adjustment corresponding to the eccentricity of the spigot 34d.
  • the eccentricity is about 7mm.
  • the adjusted position can be set by rotating the screw 36 to advance it from the position of Figures 1 1 a, 1 1 b to the position of Figures 12a to 12c in which it simultaneously engages both of the threaded portions defined by the nuts 31 , 37.
  • This screwing in need not be a careful manual operation.
  • An electric screwdriver might be used to rapidly drive in the screw 36.
  • the nuts 31 , 37 are mounted so that they cannot rotate and as they are simultaneously engaged with a common thread, even if the screw 36 were to rotate over time, the distance between the nuts 31 , 37 is retained.
  • the disclosed pivot mount 30 includes an adjustment mechanism including the cam 34 and a locking mechanism including the screw 36 each of which can be usefully applied without the other.
  • pin 33 and spring 38 are omitted.
  • the mounting member 39 has a ceiling. A portion of the ceiling is formed of Nylon and is removable. The ceiling serves to capture the nuts 31 , 37 in their respective pockets. The removable portion provides access for the insertion of the nuts 31 , 37 during factory assembly of the mount 30.
  • This tubular portion has a rectangular internal cross-section co-operable with a rectangular external cross-section of the slide member 32 such that the slide block slides along the mounting member 39a but is restrained from rotation.
  • An end of the tubular portion opposite the pocket 39d is open to receive the slide block 32.
