Field of Invention
The invention relates to an assembly for mounting a door to a rail to allow the door to move
along the rail between open and closed positions.
Background to the Invention
Mounting a door to move along a rail between open and closed positions is well known. This configuration of door is typically referred to as a 'sliding door'. A sliding door is typically mounting to the rail via a carriage assembly, typically with one or more wheels to roll (i.e. slide)
along the rail.
Various carriage or mounting arrangements have been employed over the years to mount a
door to slide along a rail. However, there are often problems associated with installation of a door to carriage assembly on a rail. Connection of the mounting or carriage assembly to the
door can be difficult and can often require two people to lift and locate the door to the carriage
assembly.
It is also highly desirable to improve the reliability of sliding door mounting arrangements. Sliding door mounting assemblies can fail for a number of reasons. Mounting arrangements
can result in the height of the door slowing dropping over time, requiring periodic adjustments to be made. Maintenance and/or disassembly for maintenance or replacement of carriages can
be difficult, again requiring two or more people to remove a door from a rail. Some arrangements may include a latch mechanism to attach the door to the carriage, which
introduces complexities to the door mount assembly and to the installation and removal of a
door. Furthermore, latch assemblies can become jammed, for example due to debris or dirt over time, preventing disassembly such that destruction (i.e. cutting) of the mounting
arrangement is required to remove the door from the rail.
Object of the Invention
It is an object of the invention to provide an assembly to mount a door to move along a rail that addresses one or more of the above-mentioned disadvantages, or that at least provides the
public or industry with a useful choice.
Summary of the Invention
According to a first aspect of the invention, there is provided an assembly for mounting a door to a rail to move between open and closed positions, the assembly comprising: a carriage,
a mounting plate configured to be mounted to the top of the door,
a pin extending between the carriage and the mounting plate,
a connection member attached to or formed with the pin to connect the pin to the mounting plate, the connection member comprising a head and a neck, wherein the mounting plate has a slot, the slot comprising a lower portion and an upper
portion, the upper portion dimensioned to receive the neck and the lower portion dimensioned
to receive the head, and wherein the head is too wide to be received in or pass through the upper portion so that in use the door hangs from the mounting assembly with the mounting
plate bearing on the head of the connection member.
The configuration of the slot provides for an easy and simple connection of the door to the mounting assembly. The assembly may include a number of further features to simplify the
installation process of hanging the door by the mounting assembly.
In some embodiments, the height of the head is commensurate with a height of the lower
portion of the slot. The slot may be open through an end of the mounting plate to allow the connection member to be inserted into the slot from an end of the mounting plate. In some
embodiments, the mounting plate comprises a pair of tabs at an end of the mounting plate, the tabs spaced apart to present an entry or alignment slot aligned with the lower portion of the slot. The entry slot may have the same width as the lower portion of the slot. The height of the tabs may be the same as the height of the lower portion of the slot.
The mounting assembly comprises a securing plate mounted to the mounting plate to capture
the connection member within the slot. The securing plate closes an open end of the slot to
capture the connection member within the slot. The securing plate prevents movement of the connection member along the slot. The connection member is captured in a horizontal
direction between the securing plate and a closed end of the slot.
The assembly may comprise a locking member to lock the securing plate to the mounting plate. For example, the mounting plate has an aperture and the securing plate has a corresponding
aperture, and with the securing plate positioned on the mounting plate, the apertures are
aligned to receive the locking member. The locking member may be a pin or rod configured to be dropped into the aligned apertures, such that no tools are required to connect the
connection member to the mounting plate.
The mounting plate may comprise a recess or projection and the securing plate a corresponding
projection or recess, such that engagement of said recess and projection couples the securing plate to the mounting plate in a vertical direction. The securing plate is attached to the
mounting plate by sliding the securing plate on the mounting plate in a direction along the slot.
In some embodiments, the securing plate comprises a feature to engage a complementary feature on the connection member to prevent the connection member from rotation relative to
the securing plate and therefore the mounting plate. In some embodiments, the securing plate presents a lateral surface to engage a flat surface on the connection member to prevent
rotation of the connection member relative to the securing plate. The connection member may
comprise at least a pair of diametrically opposed flat surfaces for engagement by a spanner and the lateral surface of the securing plate engages one or more said flat surfaces. The securing
plate may have a recess or slot to receive the connection member. Lateral sides of the securing plate recess or slot engages one or more said flat surfaces on the connection member to prevent rotation of the connection member relative to the securing plate.
In an aspect of the invention, the connection member is attached to the pin by a threaded engagement to provide for height adjustment of the door.
In some embodiments, the carriage comprises a chassis and the assembly comprises a joint between the chassis and the pin to allow the pin to pivot relative to the chassis. The joint may
allow for the pin to pivot or rotate relative to the chassis. In some embodiments, the joint
allows for the pin to pivot or rotate relative to the chassis about a pivot axis perpendicular to a longitudinal axis of the pin and parallel to the rail. The chassis may comprise a socket, and the pin comprises a ball at an upper end received in the socket to form the joint. A pair of
diametrically opposed members may be provided between the ball and chassis on a central axis
of the ball perpendicular to a longitudinal axis of the pin.
To move along the rails, the carriage may comprise a chassis and one or wheels rotationally mounted to the chassis.
The mounting assembly of the first aspect may be configured for a sliding door assembly, for example a cavity sliding door assembly. In another aspect, the invention may provide a cavity
sliding door assembly comprising a door, a frame presenting a cavity for receiving the door when in an open position, a rail, and an assembly for mounting the door to the rail as described
in any one or more of the above statements in relation to the first aspect of the invention.
According to a second aspect of the invention, there is provided an assembly for mounting a door to a rail to move between open and closed positions, the assembly comprising:
a carriage,
a mounting plate configured to be mounted to the top of the door, a pin extending between the carriage and the mounting plate, a connection member attached to the pin to connect the pin to the mounting plate, wherein the connection member is attached to the pin by a threaded engagement to provide for height adjustment of the door.
In an aspect of the invention, the connection member comprises a head and a neck, and the
mounting plate has a slot dimensioned to receive the neck, wherein the head is too wide to be
received in or pass through the slot so that in use the door hangs from the mounting assembly with the mounting plate bearing on the head of the connection member.
In some embodiments, the mounting assembly comprises a securing plate mounted to the mounting plate to capture the connection member within the slot. The securing plate may comprise a feature to engage a complementary feature on the connection member to prevent
the connection member from rotation relative to the securing plate and therefore the
mounting plate. For example, the securing plate presents a lateral surface to engage a flat surface on the connection member to prevent rotation of the connection member relative to
the securing plate. The connection member may comprise at least a pair of diametrically opposed flat surfaces for engagement by a spanner and the lateral surface of the securing plate
engages one or more said flat surfaces. The securing plate may have a recess or slot to receive
the connection member, lateral sides of the securing plate recess or slot engaging one or more said flat surfaces on the connection member to prevent rotation of the connection member
relative to the securing plate.
The second aspect may comprise any one or more features described above in relation to the first aspect of the invention.
According to a third aspect of the invention, there is provided a method for mounting a door to
a rail to move between open and closed positions, the method comprising:
providing a mounting assembly as described in any one more of the above statements summarising the invention, attaching the mounting plate to the top of the door and engaging the carriage with the rail to move along the rail, lifting the door to engage the connection member with the mounting plate to receive the head in the lower portion of the slot and neck in the upper portion of the slot to hang the door from the mounting assembly on the rail with the mounting plate bearing on the head of the connection member.
In some embodiments, engaging the connection member with the mounting plate comprises
vertically aligning the head with the lower portion of the slot and moving the connection
member along the slot. The slot may be open through an end of the mounting plate and the method comprises inserting the connection member into the slot from the open end of the slot. The mounting plate may comprise an entry slot aligned with the lower portion of the slot
and the method comprises inserting the head into the entry slot and moving the head along the
entry slot to move the head into the lower portion of the slot and the neck into the upper portion of the slot. The height of the head may be commensurate with the height of the lower
portion the slot, and the method comprises lifting the door to contact the head with a top edge of the door, and moving the connection member along the top edge surface of the door until
the head and neck are received in the lower and upper portions of the slot.
The mounting assembly may comprise a securing plate and the method comprises attaching the
securing plate to the mounting plate to capture the connection member within the slot, for example by sliding the securing plate onto the mounting plate in a direction along the slot. The
mounting assembly may comprise a locking member and the mounting plate and securing plate with complementary apertures that are aligned when the securing plate is attached to the
mounting plate. The locking member may be dropped into the aligned apertures to lock the securing plate to the mounting plate in a vertical direction.
In an aspect of the invention, the connection member is attached to the pin by a threaded engagement and the method comprises adjusting a height of the door relative to the rail by
rotating the connection member on the pin. The securing plate may have a feature to engage a complementary feature on the connection member to prevent the connection member from rotation relative to the securing plate, and the method comprises rotating the connection member for height adjustment of the door and attaching the securing plate to the mounting plate to capture the connection member and prevent rotation of the connection member to set the height of the door.

Brief Description of Preferred Embodiments of the Invention
A cavity sliding door assembly 100 is shown in Figure 1. The sliding door assembly 100
comprises a door 101, a frame 102 presenting a cavity for receiving the door when in an open position, a rail 103, and a mounting assembly (not shown in Figure 1) for mounting the door
101 to move or travel along (herein slide) on the rail 103 between open and closed positions.
A mounting assembly 1for mounting the door 101 to the rail 103 according to an embodiment
of the present invention is shown in Figures 2A and 2B. An exploded view of the assembly 1 is shown in Figure 3. The assembly 1is configured to be attached to a top edge of the door and hang from the rail 103 to allow the door 101 to slide along the rail 103 between open and closed positions. Typically, two mounting assemblies 1 are attached to the top of the door, spaced apart along the top edge of the door (refer Figure 9), to hang the door from the rail located above the door.
The mounting assembly 1 comprises a carriage to carry the door along the rail. The carriage has wheels 2. The wheels 2 engage the rail 103 to roll (slide) along the rail 103. The carriage has a
chassis 3 to which the wheels are rotationally mounted. The illustrated embodiment has two
pairs of wheels. The wheels are mounted on axles 25 extending through the chassis 3. Other carriage configurations are possible, for example there may be one or more wheels and alternative wheel mounting arrangements, and/or the carriage may comprise alternative sliding
elements.
The assembly 1 comprises a mounting plate 4 configured to be attached to the top edge of the
door. A carriage pin 5 extends between the carriage chassis 3 and the mounting plate 4, to connect the door 101to the carriage 3 to slide on the rail 103. The mounting plate 4 has
apertures 6 to receive fasteners (not shown) therethrough to attach the plate 4 to the top of
the door.
An upper end of the pin 5 is received in a socket 7 within the chassis. The pin 5 comprises a ball 8 at the upper end, to be received in the socket 7. As best shown in Figures 7A and 7B, the
socket 7 provides a seat 7a on which the ball 8 is received. The ball 8 and socket 7 together form a ball and socket joint to allow for pivoting or rotational movement between the pin 5 and
carriage chassis 3, and therefore between the door 101 and the rail 103. A cap 9 is mounted to the chassis 3 (e.g. by a threaded engagement) to capture the ball 8 within the socket 7. The cap
9 also provides a seat 9a opposite to the carriage seat 7a to capture the ball therebetween.
A pair of diametrically opposed members (grub screws) 10 are provided to the ball 8 on a
central axis of the ball perpendicular to a longitudinal axis of the pin 5. The members 10 are received in complementary recesses or grooves 11 provided to the chassis 3 adjacent the socket 7 to restrict movement of the pin 5 relative to the chassis 3 to pivot or rotate about a pivot axis perpendicular to the longitudinal axis of the pin 5, i.e. about a horizontal axis. The pivot axis is parallel to a longitudinal axis of the rail 103 and/or is in a plane of the door 101in use. Other joint arrangements may be provided to connect the pin 5 to the chassis 3 while allowing for the door 101 to pivot relative to the rail 103 about an axis parallel to a longitudinal axis of the rail.
The assembly further comprises a connection member 12 attached to or formed with the pin 5.
The connection member 12 connects the pin 5 to the mounting plate 4 to thereby couple the door 101to the carriage.
The mounting plate 4 is best illustrated in Figures 4A and 5A to 5D. The mounting plate 4 has a
slot 13 to receive the connection member 12 to connect the pin 5 to the mounting plate 4. The slot 13 has lower portion 13a and an upper portion 13b. The upper portion 13b is narrower
than the lower portion 13a. As shown in Figure 3, the connection member 12 has a head 12a to be received in the wider lower portion 13a, and a neck 12b to be received in the narrow upper
portion 13b. The upper portion 13b of the slot is dimensioned to receive the neck 12b, and the
lower portion 13a is dimensioned to receive the head 12a. The head 12a is too wide to be received in or pass through the narrow upper portion 13b of the slot 13, such that the door
hangs from the mounting assembly 1 with the mounting plate 4 bearing on the head 12a of the connection member 12. The head presents a shoulder 12c (Figure 3) to bear on a
corresponding shoulder 13c (Figure 5B) on the mounting plate.
To insert the connection member 12 into the slot 13, the head 12a is vertically aligned with the wider lower portion 13a of the slot 13. The connection member 12 is moved along the slot 13
to receive the head 12a of the connection member 12 in the lower portion 13a of the slot and
the neck 12b of the connection member 12 in the narrow upper portion 13b of the slot, to couple the pin 5 to the mounting plate 4, as shown in Figures 7A and 7B.
In the illustrated embedment, the slot 13 is open through an end of the mounting plate 4, to allow the connection member 12 to be inserted into the slot 13 from an end of the mounting
plate 4, for example from an open end of the slot.
In the illustrated embodiment, the mounting plate 4 has a pair of tabs 14 at an end of the
mounting plate 4. The tabs 14 are spaced apart to present an entry or alignment slot 15
aligned with the lower portion 13a of the slot 13. The entry slot has the same width as the lower portion 13a of the slot 13. In the illustrated embodiment, the height of the tabs 14 is the
same as the height of the lower portion 13a of the slot 13. To insert the neck 12b of the
connection member 12 into the upper portion 13b of the slot 13, the head 12a is initially placed in the entry slot 15 (with the neck 12b above the tabs 14). The connection member 12 can then be moved along the entry slot 15 to then move the head 12a into the lower portion 13a of the
slot and the neck 12b into the upper portion 13b of the slot, to connect the mounting place 4 to
the carriage. Thus, the entry slot 15 forms a guide, to align the connection member 12 in a horizontal direction with the slot 13 so that the neck 12b and head 12a are easily received into
the 13 slot (the connection slot) of the mounting plate 4.
In the illustrated embodiment, the height of the head 12a is commensurate with (matched to)
the height of the lower portion 13a of the connection slot 13, so that the head 12 is configured to engage a surface immediately below the lower portion 13a of the slot 13 to vertically align
the head 12a with the lower and the neck 12b with the upper portion of the slot. In the illustrated embodiment, the upper portion 13b of the slot extends through an upper surface of
the mounting plate 4 and the lower portion 13a of the slot extends through a lower surface of the mounting plate 4. In use, with the mounting plate 4 mounted to a top of the door 101, the
top edge of the door provides a surface immediately below the lower portion 13a of the slot 13. To insert the connection member 12 into the slot 13, the head 12a of the connection member
may be placed against the top edge of the door, i.e. by lifting the door 101to contact the head
12. The connection member 12 can then be moved along the top edge surface of the door 101 until the head and neck are received in the lower and upper portions 13a, 13b of the slot. Thus, the configuration of the mounting plate assists with aligning the connection member with the mounting plate slot in a vertical direction.
The mounting assembly further comprises a securing plate 16. The securing plate is best illustrated in Figures 4A and 6A to 6D. The securing plate 16 is provided to the mounting plate
4 to capture the connection member 12 within the slot 13, as shown in Figures 2A, 2B, 7A and
7B. The securing plate 16 closes the open end of the slot 13 to capture the connection member 12 within the slot 13. With the securing plate 16 attached to the mounting plate 4 the
connection member 12 cannot be removed from the mounting plate 4. The securing plate 16
prevents movement of the connection member 12 along the connection slot 13 in the mounting plate 4. The connection member 12 is captured in a horizontal direction between the securing plate 16 and a closed end of the connection slot 13.
The assembly 1 comprises a locking member to lock the securing plate 16 to the mounting plate 4. The illustrated embodiment has an aperture 17a in the mounting plate and a corresponding
aperture 17b in the securing plate 16, refer Figure 4. With the securing plate 16 positioned on the mounting plate 4 to capture the connection member 12, the aperture 17b of the securing
plate 16 is aligned with the aperture 17a on the mounting plate 4. As shown in Figure 8, the
locking member 18 is received in the aligned apertures 17a, 17b to lock or attach the securing plate 16 to the mounting plate 4.
The locking member 18 is a pin or rod that is configured to be dropped into the aligned
apertures 17a, 17b. A screw type fastener may be used as the pin or rod, as illustrated in Figure 8, however the major diameter of the fastener screw thread is less than the inner diameter of
the apertures 17a, 17b so that the fastener may be dropped into the aligned apertures 17a, 17b. The locking member 18 couples the securing plate 16 to the mounting plate 4 in a
horizontal direction (i.e. a direction perpendicular to the longitudinal axis of carriage pin).
The illustrated embodiment has an aperture 17a, 17b adjacent each longitudinal edge of each
of the mounting plate 4 and the securing plate 16 so that there the aperture 17a, 17b to receive the locking member 18 is accessible from each side of the door 101for easy access by an installer. A locking member 18 may be provided to one pair of aligned apertures 17a, 17b only.
The mounting plate 4 comprises a recess 19 to receive a corresponding projection 20 of the securing plate 16, to couple the securing plate 16 to the mounting plate 4 in a vertical direction.
With reference to Figures 4 to 6D, the illustrated embodiment has a pair of projections 20, each
projection to be received in a corresponding recess 19 in the mounting plate. Each recess 19 is adjacent a side of the entry slot 15 of the mounting plate 4. The recess(es) and projection(s)
are configured so that, to attach the securing plate 16 to the mounting plate 4, the securing
plate 16 is slid onto the mounting plate 4 in a direction along the slot 13 to receive the projections 20 in the corresponding recesses 19. The projections 20 received in the recesses 19 couple the securing plate 16 to the mounting plate 4 in a vertical direction (i.e. a direction
parallel to the axis of the carriage pin). The recesses are in a bottom surface of the mounting
plate 4 so that the projections 20 are captured between the mounting plate 4 and a top of the door. Alternatively, one skilled in the art will understand that the mounting plate 4 may be
provided with one or more projections to be received in corresponding recess(es) in the securing plate to couple the securing plate 16 to the mounting plate 4 in a vertical direction.
With reference to Figures 3, 7A and 7B, in the illustrated embodiment, the connection member 12 is attached to the carriage pin 5 by a threaded engagement (21 in Figures 7A and 7B). The
pin 5 has a male thread and the connection member a corresponding female thread. The threaded engagement 21 between the pin 5 and the connection member 12 provides for height
adjustment of the door 101 relative to the rail 103 and therefore a door jamb in which the door is received. Once the door 101is hung by the mounting assembly, an installer can make a final
height adjustment of the door in the doorjamb by rotation of the connection member 12 on the pin 5. The connection member 12 has diametrically opposed flats 22 to be engaged by a
tool, for example the connection member 12 has a hexagonal outer form for engagement by a
spanner, to allow an installer to rotate the connection member 12 on the pin 5. To increase the height of the door 101, the connector member 12 may be threaded up the carriage pin 5 such that a bottom end of the carriage pin 5 may extend downwards into a cavity or recess of the door 101, e.g. a space between two side panels or skins of the door.
The securing plate 16 comprises a feature to engage a complementary feature on the connection member 12 to prevent the connection member 12 from rotation relative to the
securing plate 16 and therefore the mounting plate 4. Rotation of the carriage and carriage pin
5 relative to the rail 103 about a vertical axis is largely prevented by engagement between the carriage and the rail 103, with the carriage received on the rail 103. Further, the door 101 is
largely prevented from rotation relative to the rail 103 about a vertical axis by members (refer
members 104 in Figure 9) secured to the top of the door 101 engaging the rail and/or by there being two or more mounting assemblies 1 spaced apart along the top of the door. Thus, by preventing relative rotation between the connection member 12 and the securing plate and
therefore the mounting plate 4, the securing plate 16 prevents relative rotation between the
connection member 12 and the carriage pin 5, so that the height of the door within the door jamb does not 'creep' or slowly drop over time. This arrangement prevents or reduces the
requirement for the door height to be reset or readjusted after a period of use.
The securing plate 16 presents a lateral surface 23 to engage a flat surface 22 on the connection
member 12 to prevent rotation of the connection member 12 relative to the securing plate 16. The lateral surface 23 of the securing plate 16 engages a flat 22 of the hex on the connection
member 12. In the illustrated embodiment, the securing plate 16 has a recess or slot 24 to receive the connection member 12 when the securing plate 16 is attached to the mounting
plate 4. Lateral sides 23 of the securing plate slot 24 engage diametrically opposed flats 22 on the connection member 12 to rotationally couple the connection member 12 to the securing
plate 16 to prevent relative rotation therebetween. In the illustrated embodiment, a closed end of the securing plate slot 24 is configured to engage two flats 22 on the connection
member 12. Thus, in the illustrated embodiment, the securing plate 16 engages four flats on
the connection member 12 (as shown in Figures 2A and 2B). However, one skilled in the art will appreciate that the securing plate may engage one flat or other feature of the connection
member 12 to prevent relative rotation therebetween.
Embodiments of the present invention provide one or more of the following benefits:
• Installation of a sliding door to a rail is simplified and allows for a quick installation by a
single person. Disassembly is correspondingly also simplified.
• The connection member on the carriage pin is easily aligned with the slot in a vertical
direction by lifting the door to contact the top edge of the door with the connection
member.
• The slot is open to an end of the mounting plate so that the connection member can be
moved along the top of the door to be received into the open end of the slot. • Height adjustment of the door relative to the door jamb is simply achieved by rotation
of the connection member at the top of the door. • The carriage pin is easily captured at the mounting plate by the installation of the
securing plate. The securing plate is simply slid into place on the mounting plate.
• No tools are required to lock or attach the securing plate to the mounting plate. The securing plate is locked to the mounting plate by simply sliding the securing plate into place on the mounting plate and dropping a pin into the aligned apertures in the
securing plate and mounting plate.
• A height adjustment thread is provided between the connection member and the pin,
rather than between the pin and the ball of the ball joint at the carriage. This allows for a larger thread to be provided compared to a thread size that can be accommodated at
the ball, and therefore provides a more robust connection of the door to the carriage. • The engagement of the securing plate to the connection member prevents creep or
movement of the door over time. Accelerated life cycle testing has proven no change or creep in height setting of the door over 1 million cycles (500 thousand open/close
operations). The door mounting arrangement is therefore expected to be largely maintenance free.
Where in the foregoing description reference has been made to integers or components having
known equivalents thereof, those integers are herein incorporated as if individually set forth.
