[0001] The present invention relates to hinges for doors, windows, gates or the like.
[0002] For conciseness and clarity, the term "door" used herein is intended to embrace any
hinged member, including windows, gates, hatches, doors, etc.
[0003] Traditionally there have always been difficulties associated with the hanging of
doors, gates etc. on their hinges such that they sit correctly in their frame. This
often involved mounting the door and hinge and then removing it to make adjustments
to position of the fasteners and so on.
[0004] It is therefore desired to provide a hinge which allows the installer to hang the
door and carry out positional adjustments while the door is in place. This allows
the installer to make adjustments and to immediately see the effect without having
to repeatedly hang and remove the door from the hinge. Two such adjustable hinges
are described in DE-A-370531 and DE-U-92 03 856.
[0005] According to the present invention there is provided a hinge comprising:
a fixing portion for attachment to a door frame;
a spindle supporting portion slidably attached to the fixing portion;
a door attachment means for attachment to a door;
a spindle engaged with said spindle support means, said spindle including an axially
eccentric central portion on which the door attachment means is rotatably mounted;
and means for selectively preventing rotation of said spindle relative to said frame
attachment means,
the spindle supporting portion being restrained from moving downwards relative to
the fixing portion by a retaining means which may be adjusted, whilst the hinge is
supporting a door, to slidably vary the relative position of the spindle supporting
portion on the fixing portion.
[0006] The adjustable retaining means allows the user to slidably adjust the relative position
of the spindle support portion relative to the fixing portion. This allows fine adjustment
of the mounting height of the door.
[0007] The adjusting means may be provided by screwing a bolt into the fixing portion through
a hole in the spindle supporting portion, with the spindle supporting portion resting
on the head of the bolt such that as the bolt is screwed into the fixing portion,
the head of the bolt moves towards the fixing portion carrying the spindle supporting
portion with it.
[0008] The hinge may include a second spindle supporting means which is slidably attached
to the fixing portion and which engages the top of the spindle.
[0009] The means for preventing the rotation of the spindle may comprise providing splines
on the end of the spindle which engages with one of the spindle supporting means to
prevent rotation of the spindle. The splined portion is preferably provided on the
upper end of the spindle and in the second spindle supporting portion. This means
that, with the second spindle supporting portion removed, the spindle can rotate in
the first spindle supporting portion whilst supporting the weight of the door. When
the spindle is in the desired position, the second spindle support portion can be
moved into position to lock the spindle in position.
[0010] The fixing portion is preferably rectangular in shape having angled edges to form
a "dove-tail" shape. The shape of the spindle supporting portions can be matched by
providing them with a corresponding shape, i.e. by having two arms with protruding
portions on the end which hook around the edge of the fixing portion at the angled
edges thereon. The fixing portion may, however have a variety of shapes. For example,
by providing one or more ribs or grooves along the sides.
[0011] A further adjustment may be provided on the door attachment means to allow adjustment
of the length between the door connection part and the spindle connection part, to
provide further positional adjustment of the door.
[0012] An embodiment of a hinge according to the present invention will now be described
with reference to the following drawings in which like reference numerals refer to
like parts:
Figure 1 shows a disassembled view of the hinge according an embodiment of the present
invention.
Figure 2 shows a top view of the spindle supporting portion.
[0013] Figure 3 shows a bottom view of the spindle supporting portion.
[0014] Figure 4 shows a view of the hinge with the spindle and second spindle supporting
portion removed, looking from the door side of the hinge.
[0015] Figure 5 shows a side view of the hinge with the spindle and second spindle supporting
portion removed.
[0016] Figure 6 shows the door attachment portion.
[0017] Figure 7 shows a sectional view through the hinge with the door attachment portion
in position.
[0018] Figure 8 shows a bottom view of the second spindle support portion.
[0019] The hinge 1 includes a frame attachment part 3,4 which comprises a spindle supporting
portion 3 and a fixing portion 4, which is substantially rectangular through the sides
which face the wall, in use, have angled edges 11 to provide a "dove-tail" shape.
The angled edges are provided for engaging correspondingly shaped protrusions 21 on
two spindle supporting portions 3,8 which are attached to the top and bottom of the
fixing portion. The fixing portion 4 also has two protruding shafts 10 which are inserted
into holes provided in the frame which, along with the screws passed through screw
holes 40 also provided in the fixing portion, serve to provide load bearing support
for the hinge.
[0020] Once the fixing portion is located on the frame and screwed into position, the lower
spindle supporting portion is attached to it. This is achieved by sliding the lower
spindle supporting portion 3 onto the bottom of the fixing portion 4, then screwing
a retaining bolt 30 into the bottom of the fixing portion through a hole 31 provided
in the bottom of the lower spindle portion. Once the retaining bolt has engaged the
fixing portion, the head of the bolt will support the lower spindle supporting portion.
[0021] A door mounting part 61, which is pivotally mounted on a spindle 2, is attached to
the door or gate which is to be hung. The spindle comprises two co-axial end sections
6,7 and an eccentric central portion 5 having its axis offset from the two end sections.
The upper end of the spindle is provided with a series of splines 9 for engaging corresponding
splines 81 provided in the upper spindle supporting portion 8, described below. The
door mounting part is attached to the spindle, so that it pivots on the eccentric
portion.
[0022] The door (not shown), with the door mounting part and spindle attached, is lowered
into its mounting position so that the lower end of the spindle 7 drops into a recess
20 in the upper surface of the lower spindle supporting portion. The weight of the
door is then supported by the spindle which is supported by the lower spindle supporting
portion.
[0023] In this position, with the door supported, the installer can carry out fine tuning
of the positioning of the door.
[0024] Firstly, the retaining bolt 30 located at the bottom of the lower spindle supporting
portion can be turned to provide height adjustment. By screwing the retaining bolt
further into the fixing portion, the lower spindle supporting portion is raised which
in turn raises the spindle and consequently the door. To protect and hide the head
of the retaining bolt, a recess 32 is provided on the base of the lower spindle supporting
portion in which the head of the retaining bolt 30 is located.
[0025] In order to provide adjustment of the position of the door in and out of the frame
(i.e. to the left and right in figure 5) the spindle is rotated in the receiving hole
20 in the lower spindle supporting portion. As the spindle is rotated, the eccentric
central portion 5, to which the door is indirectly attached, rotates causing its axis
to move in a circular orbit around the axis of the end portion of the spindle. This
allows the door to be moved in and out of the frame.
[0026] Once the desired position has been obtained the upper spindle supporting portion
is slid into place. The upper spindle supporting portion, like the lower spindle supporting
portion, have a "dove-tail" engaging portion 82 to allow it to slide down the fixing
portion from the top. The upper spindle supporting portion is provided with a splined
receiving hole 81 which engages the upper splined section of the spindle. This engagement
locks the spindle, preventing any further undesirable rotation of the spindle.
[0027] A further adjustment may be provided to allow left/right adjustment of position of
the door. This is provided by providing a screw adjustment 60 to allow the part of
the door attachment part connected to the door to move relative to the part attached
to the spindle.
[0028] Alternatively, instead of the arrangement of splines on the spindle and upper spindle
supporting portion, other means may be provided to selectively lock the spindle against
rotation in the frame attachment portion. For example a grub screw could be provided
in the upper spindle supporting portion which is screwed against the edge of the spindle
in a smooth recess which replaces the splined recess 81. This grub screw when screwed
into the upper spindle supporting portion would lock the spindle.
