Definitions

  • the present invention relates to an adjustable hinge for securing a panel to a support structure.
  • it relates to an adjustable hinge which allows a panel to rotate relative to a support structure through a range of positions wherein there is at least one rotational position in which said panel is substantially fixed relative to the support structure.
  • substantially fixed means that the panel cannot be rotated out of position without exerting a substantial amount of force on the panel, i.e. it cannot swing by itself or by subjecting it to a minor torque.
  • the adjustable hinge provided by the present invention is in particular applicable for a door to be used as a shower splashing protection.
  • Hinges for securing swiveling panels such as e.g. doors, gates, wickets, hatches, lids, covers, windows and the like, have been known for centuries or maybe millenniums.
  • pivotally adjustable hinges for securing such swiveling panels pivotally about an axis of rotation and having at least one rotational position about said axis in which said panel is substantially fixed, are well-known and are disclosed in the prior art, e.g. WO 2006/054942 A1 , WO 2005/102128 , and EP 1 630 333 A1 .
  • pivotally adjustable hinges of the prior art are mainly designed with the object to simplify their manufacturing processes and general versatility, but the installation and adjustment in situ of a panel secured thereto are hampered by the fact that usually at least two persons are required to perform this job making it both cumbersome and costly.
  • WO 2006/054942 A1 discloses improvements in or relating to a hinge intended to be used together with a glass door in the form of a shower splashing protection and comprising a fixed profile attachable to a wall and a pivotal profile supporting the glass door, said profiles pivot around upper and lower pivots provided on end fittings in a predetermined distance from the fixed profile, said pivotal profile consists of a tube having along its mantle surface at least one fixing means for supporting the glass door and at least one bushing attached to each free end of the tube, having a centrally located opening for supporting and cooperating with the upper and lower pivot, respectively, and at least one transverse recess, provided in at least the lower bushing, in order to cooperate with a correspondingly formed bulge for position fixation of the pivoting angle position location of the glass door, said hinge being characterized in that the bulge is formed on a position washer, which is pivotally provided around the pivot of the lower end fitting between the said end fitting and its adjacent bushing, said position washer is lockable during its turning movement in
  • WO 2005/102128 discloses a pivotal type of hinge for a door leaf, a window and the like, which hinge has a pin pivotally on its longitudinal axis and comprising a holder for the door leaf, the window and the like, and a connecting part.
  • One end of the pin and a first carrier plate engage each other by cam surfaces
  • the other end of the pin and a second carrier plate engage each other by cam surfaces.
  • Means are arranged to lock the respective carrier plates to the connecting part and unlock the respective carrier plates from the connecting part so as to allow both a left- and a right-hung door leaf, window and the like.
  • the carrier plates may also be rotational adjusted about the longitudinal pivotal axis of the pin so as to adjust the desired open and closure position of the door leaf.
  • the locking and unlocking means may be screws.
  • the screws secure fixation of the open and closure positions. However, if a distortion of the shower cabinet sheets or the connecting part occurs it is not easy to correct for that. The screws have to be loosened and a refitting becomes difficult because it is difficult to identify the reference position.
  • EP 1 630 333 A1 describes a hinge, in which open and/or closure positions can be adjusted, said hinge has a support in the form of a square and a body for mounting a swiveling panel.
  • the support has a slot adapted to be constricted by tightening means (e.g. a screw) for pressing a cylindrical sheath of an indexing block.
  • the sheath surrounds a rotation axis of the body and presents a grip.
  • the sheath is coaxial with the axis, and tightening means (e.g. a screw) is mounted in one of two flanges of the support.
  • the open and/or closure positions of the axis of rotation are defined by its indexed vertical recesses of the indexing block and the position of the grip.
  • the mechanism for securing a stable position of the open or closure position is effected by means of a roller, which are placed in a top and a down cap onto which springs exert a strong pressure to secure stable open or closure positions.
  • a roller which are placed in a top and a down cap onto which springs exert a strong pressure to secure stable open or closure positions.
  • the same drawbacks as above also apply to this hinge.
  • an adjustment of the open and/or closed positions requires the following separate steps: first the tightening means must be loosened; then the indexing block is rotated to move the position of its recesses; finally the tightening means is tightened to so as to constrain the indexing block.
  • Such is complicated and several small adjustments may be required in order to iteratively find the optimum arrangement, which will be rather time consuming owing to these several steps.
  • the clamping and unclamping of the indexing block affected by the tightening means may lead to damage, in particular wearing of a finishing coating and subsequent corrosion.
  • the prior art comprise hinges which may be easy to manufacture and may have general versatility, but require too much manpower for their mounting and adjustment. Due to the weight of a door two persons are needed when the screws of the hinges are to be loosened or tightened when adjusting the closure and/or open positions of the door in order to obtain a satisfactory result. Besides, whenever a readjustment is needed one fitter cannot perform the readjustment himself as it requires an unlocking and locking procedure and by unlocking the fixing screws the initial angle position of the hinge goes lost together with the reference point for the adjustment, so only by cumbersome trial and error a proper readjustment can be performed.
  • Such an arrangement is simpler to install and/or adjust than prior art hinges due to the use of a single worm drive to facilitate the adjustment and locking of the fixed positions. This is due, in particular, to the fact that a single adjustment action is required.
  • the combined adjustment and locking means may be a worm drive comprising: a wheel provided with a gear segment arranged on its outer curved surface and which is disposed on the second member; and a worm which is connected to the first member.
  • Said worm and gear segment may be operable to mutually engage so that: (a) rotation of the worm rotates the wheel which in turn alters the one or more positions wherein relative movement is limited; and (b) the worm locks the position of the wheel. That is, the single action may comprise rotation of the worm.
  • the second surface may be disposed on the wheel.
  • the position of the wheel may be locked by means of the pitch of the worm and/or the gearing ratio of the worm drive.
  • the first and second surfaces may be substantially annular in shape.
  • One or more rounded projections may be provided on the first surface and one or more complementary rounded depressions may be provided on the second surface.
  • one or more rounded projections may be provided on the second surface and one or more complementary rounded depressions may be provided on the first surface.
  • two rounded projections are provided, which are are angularly displaced from each other by approximately 180 degrees and two rounded depressions are provided, which are angularly displaced from each other by approximately 90 degrees.
  • the first surface may be substantially tilted or wedge shaped, and the second surface may be a corresponding but inverted shape.
  • the biasing of the first surface towards the second surface may be achieved by the action of the weight of the first member and/or a panel attached thereto.
  • the wheel may be arranged to lie substantially horizontally and the second surface may form the upper surface of the wheel.
  • the second surface may be the curved surface of the wheel and the second surface may be provided with one or more rounded depressions.
  • the first surface may be a corresponding engaging ball or roller which is movably attached to the first member.
  • One or more springs, or any other biasing means, may be employed to bias the first surface towards the second surface.
  • the panel may be a door, a gate, a hatch, a lid, a cover, a window or any other type of panel as is desired and/or required.
  • the axis of rotation of the wheel upon which the gear segment is disposed is substantially parallel to the axis of rotation of the first member about the second member.
  • the axis of rotation of the worm is, preferably, substantially perpendicular to the axis of rotation of the first member about the second member.
  • the worm may be operable to engage with a tool, such as a screwdriver or a hex key, in such a manner that movement of the tool may cause rotation of the worm and, consequently, alteration of the one or more positions wherein relative movement is limited.
  • a tool such as a screwdriver or a hex key
  • the gear segment may comprise gear teeth arranged around the entire circumference of the wheel.
  • the gear segment may comprise gear teeth arranged only part of the circumference of the wheel.
  • a further embodiment of the pivotally adjustable hinge according to the invention is characterized in that the engaging ball or roller provided resiliently movable or sliding in a member forms an indexing block.
  • the hinge provided by the present invention is particularly applicable for a door to be used as a shower splashing protection.
  • Such door may be attached to a fixed profile via a pivotally hinge supporting the door and having an axis of rotation.
  • the fixed profile is attachable to a wall.

Because the thread of the worm 81 engages the cogs 85 of the wheel 80 a rotation of the worm will cause a rotation of the wheel about its center axis, but due to the pitch of the thread of the worm 81 and the gearing ratio between the worm and the wheel the latter will be completely fixed in any angular position defined by the rotational position of the worm. This will also fix the angular positions of the longitudinal recesses 82, 83, 84 at the circumference of the wheel 80.
  • Fig. 12 is a side elevation of a hinge according to the present invention of the type shown in Fig. 6 and comprising an indexing block with parts broken away; the elevation is parallel to a door leaf attached thereto.
  • a worm and wheel assembly 81, 80 is disposed in the space between the lobes 86, 87 of the bracket 61 and secured therein by the tube 78.
  • the indexing block 70 shown in cross section, has a cavity 95 and two cylindrical bores 96, 97 each of which accommodates a strong spring 98, 99 or other biasing means bearing against a hollow abutment 94 (also shown in cross section).
  • a roller 100 is seated in said hollow abutment 94, which in turn bears against the circumference of the wheel 80 due to the resilient force exerted by the springs 98, 99.
  • Fig. 13 which is a section along the lines B-B in Fig. 12 , angular fixed positions of the indexing block 70 and consequently the clutch plates 62, 63 secured thereto are only obtained when the roller 100 rests in one of the longitudinal recesses 82, 83, 84 of the gear wheel 80.
  • these positions can be used to fix the open and/or closed positions of a door leaf or other panel member squeezed between the clutch plates 62, 63.
  • the angular positions of the recesses or depressions 82, 83, 84 can be changed by rotating the worm 81 by means of a tool introduced into the opening or bore 92.
  • precise continuous and optional tiny adjustments of the open and/or closed positions of a door leaf or other panel are quite easy to perform for one single person.
  • the bracket 61, the clutch plates 62, 63 and the indexing block 70 are preferably made of a metal such as brass although other appropriate metals like stainless steel may alternatively be used.
  • the visible external surfaces of these objects may be plated, e.g. with nickel or chromium and others providing an attractive appearance.
  • the worm and other screws may also be made of an impact-proof plastic but are preferably made of an inert metal like stainless steel.
