Description
Sliding door system
The invention relates to a sliding door system with a sliding
door that ally may be moved into a parking space.
Sliding door systems comprise at least one sliding door that
is ded on at least two carriages that are guided in a
guide rail. The guide rails are firmly mounted by means of
mounting screws at a ceiling or a wall or are releasably
mounted by means of a fixing device at a mounting profile,
which is firmly mounted on a ceiling or a wall.
US6647590B2 discloses a rail device with a mounting profile
that comprises two legs for receiving a guide rail. The first
leg comprises of the mounting profile comprises openings for
passing through fixing screws which the mounting e can
be connected to the wall. The second leg is provided with a T-
profile-shaped longitudinal slot which is open s the
rail and which serves for receiving and holding locking
elements that are connected to ng screws, with which the
guide rail is mounted.
The mounting e and the guide rail corresponding thereto
can already during manufacturing be provided with bores for
the mounting screws. The mounting profile is mounted in
advance whereafter mounting of the guide rail can be done with
little effort. Applying bores and/or cutting threads for
mounting the guide rail is not required, so that the same time
contamination or a mechanical impairment of the guide rail is
avoided. Thereby an optimal function of the guide rail and the
carriages guided there in is ensured.
Connection of the guide rail to the pre-mounted ng
profile can easily be done. The locking elements are inserted
HAWA 16-01 EP / 06.04.17
into the longitudinal slot of the mounting profile, turned
from a first position to a second position and subsequently
forced and by turning the mounting screws into the same
direction. As well the guide rail can easily be released and
mounted again, if access is given to the locking elements.
r, sliding door s often comprise guide rails,
which are extending into a parking space, which is delimited
by room walls that are mounted after the installation of the
guide rail and n which a part of the guide rail and the
sliding door, which has been driven into the parking space, is
ed. If a repair of the guide rail or components
installed n, such as buffer devices or pulling devices
and/or damping devices, is required, then that these devices
are barely accessible and not is mountable without removing or
destroying the room walls.
US1945332A ses a further device for mounting a guide
rail. This device comprises a rail holder that embraces the
guide rail and that comprises a larger cross-section with a
free space, in which a symmetrically formed clamp is provided,
which comprises two wings. In the centre the clamp is held by
a screw. When tightening this screw, the wings are pressed
downwards against the guide rail, which is thus fixed by the
clamp. Hence, this device requires in a first step to enter
the guide rail into the cross-section of the rail holder and
in a second step tightening of the screw arranged above the
guide rail, which is undesirable since screws are ly
accessible above the guide rail.
DE10012511A1 discloses a sliding door system with a rail
device, which comprises a ng rail installed in a
building, a guide rail in which carriages connected to a
sliding door are displaceably held as well as a plurality of
coupling devices, which serve for connecting the guide rail to
HAWA 16-01 EP / 06.04.17
the mounting rail. The coupling devices comprise each a
mushroom-shaped coupling head that is connected to the guide
rail and that can be anchored in a coupling opening, which is
ed in the mounting rail and which has the form of a
e with a larger and a r opening part. For
connecting the guide rail to the mounting rail the coupling
heads are inserted into the larger opening part of the
coupling opening and are moved against the r opening
part of the coupling opening, in order to lock the coupling
heads. For performing adjustments, repairs or maintenance the
guide rail is often dismounted. Thereby, the guide rail is
shifted back until the ng heads are again coaxially
d with the larger opening part of the coupling opening.
The guide rail is often shifted forcefully so that the coaxial
alignment of the coupling heads with the larger opening part
of the coupling opening often succeeds only after several
trials in which the guide rail engages in the mounting rail.
It must be noted that the installer performs its work usually
on a ladder and cannot overview the alignment of the coupling
heads relative to the coupling openings. Hence the described
working process requires erable .
A further device of this kind, with which the same effort is
required when mounting and dismounting the guide rail, is
described in DE202015105569U1.
The present ion is therefore based on the object of
providing an improved sliding door system, which does not
suffer from the disadvantages described above.
In particular, a sliding door system shall be created, which
allows the guide rail to be mounted or dismounted on a
mounting rail.
HAWA 16-01 EP / 06.04.17
Vibrations and noise which frequently occur with known sliding
door systems shall be avoided.
The rail device shall advantageously usable with sliding door
systems that comprise a parking space, into which the sliding
door can be displaced. It shall be possible, to quickly
perform nance, repair or the replacement of the guide
rail, without ng parts of the parking space.
An exchange of the guide rail shall be executable without
automatic guiding, so that the installer does not need to pay
attention to the exact alignment and mutual displacement of
the guide rail and the mounting rail thus excluding ect
lation.
This object is reached with a sliding door system that
comprises the features defined in claim 1. Preferred
embodiments of the invention are defined in further claims.
The t invention provides a sliding door system with a
rail device, which comprises a mounting rail mountable in a
building, a guide rail in which at least two carriages that
are connected to a g door are held displaceable along
a guide axis, as well as a plurality of coupling devices,
with which the guide rail and the mounting rail are releasably
connected with one another and which comprise each a coupling
head that is connected to the guide rail or to the mounting
rail, that comprises a coupling plate, which has an upper
side and a lower side, and a coupling neck, which adjoins the
lower side of the coupling plate, and that can be anchored in
a coupling opening, which is provided in the ng rail or
the guide rail and which comprises a first opening part with
a diameter that is larger than a diameter of the coupling
plate, and a second g part adjacent thereto with a
er larger than the diameter of the coupling neck but
smaller than the diameter of the coupling plate, wherein at
least on one side of the coupling head and at the lower side
of the coupling plate a ramp is provided, which, in a
direction towards the ng neck, increases in height
s the coupling plate. The ramp, which preferably is
aligned at least approximately in parallel to the guide axis
and, after installation, is facing the first opening part of
the coupling opening, allows releasing the guide rail from
the mounting rail in a simple manner. When the installed guide
rail is forcefully moved relative to the mounting rail, in
order to align the coupling head and the first opening part
of the coupling opening above one another, the ramp prevents
the coupling plate from transferring the edge of the first
opening part of the coupling g and to engage on the
other side below the central member of the ng rail.
Instead, the ramp hits the edge of the first opening part
and, by gliding across the edge of the first opening part,
ers the coupling plate through the first opening part
of the coupling opening. The process runs analogously, if the
coupling heads are mounted on the mounting rail and the
coupling openings are provided on the guide rail.
When shifting the guide rail, it is therefore ensured that
the ng heads get smoothly released from the guide rail
or mounting rail without hooking in at another position. By
at least one of the ramps the decoupling process is actively
supported.
The ramp can be an integral part of the coupling head or can
be part of a device member, which can be coupled to the
coupling head in a force-locking and/or form-locking manner.
The ramp can be made from the same or other material is used
for the coupling head. The ramp can be made from metal or
plastic or a combination thereof. A ramp made of plastic may
be equipped at the front side facing the edge of the first
opening part with an insert made of metal. With this
combination the ramp ts due to the elastic member a
desirable elasticity when the ramp hits the edge of the first
opening part and due to the metal insert a desirable rigidity
when the ramp moves across the edge of the first opening part.
In preferred embodiments the ramp therefore consists of an
elastic member and a metal member preferably a metal insert
held by the c member.
The ramp has a face side that is facing the edge of the first
opening part (when led) and that is straight or curved.
The broadness of the ramp is preferably smaller than the
diameter of the coupling neck so that it does not form an
obstacle when the coupling neck is moved into the second
opening part of the ng opening. The height of the ramp
preferably corresponds to the height of the coupling neck so
that the ramp preferably ends below or nt to the lower
side of the coupling plate.
The ramp preferably exhibits the form of a plate with an
inclined front face or deform of a segment of a cone.
The two opening parts of the coupling opening are preferably
rounded, so that the coupling plate of the coupling head can
be guided practically unobstructed h the first opening
part and still only a minimum ing of the related central
member occurs.
Hence, the coupling plate of the coupling head can be guided
through the first opening part of the coupling opening,
whereafter the guide rail and the mounting rail are mutually
shifted in parallel to the guide axis such, that the coupling
neck is introduced into the second opening part and is
anchored there. The region of the guide rail, which borders
the second opening part, serves therefore as flange that holds
HAWA 16-01 EP / 06.04.17
the coupling plate, which has been guided through the coupling
g, so that the coupling plate can no longer escape back
through the ng opening and the connection between the
guide rail and the mounting rail is established. Finally, the
guide rail and the mounting rail or preferably mutually
locked, e.g. by guiding a bolt or a screw through the guide
rail and the mounting rail.
Hence, after the lation of the mounting rail, the guide
rail can be lifted s the mounting rail and shifted and
so be coupled with the ng rail and preferably locked. In
the same, the installed guide rail can be unlocked after the
installation, grasped outside the parking space, if present,
shifted backwards and be released from the mounting rail.
Thereby, the installation of the mounting rail is done in a
known the way, whereby it is taken care that the mounting rail
it horizontally aligned in the selected height.
In a preferred embodiment the guide rail and the mounting rail
comprise each a l member, which is either ted to
the coupling head of the coupling devices or is provided with
the coupling opening. The parts of the coupling devices or
therefore exchangeable and can be mounted on the guide rail or
the mounting rail as d.
The central member of the guide rail is preferably provided on
both sides each with a side member and with at least one
coupling flange distant and aligned in parallel thereto,
optionally a flange plate. The first side member or the first
side s form together with a rail foot, on which the
wheels of the carriage can be seated, each an L-profile.
The central member of the mounting rail is preferably also
provided on both sides each with a side member, which is
dimensioned and aligned such that, then mounting the rail
HAWA 16-01 EP / 06.04.17
device, the side member can enter a coupling space provided
between the at least one coupling flange and the side member
of the guide rail ouring o. Hence, during the
process of mounting the guide rail, the guide rail and the
mounting rail can provisionally be coupled with one another
before the ng heads are introduced into the coupling
openings and are anchored. This process is facilitated by the
provisional coupling.
The at least one coupling flange therefore allows the guide
rail to be provisionally coupled with the mounting rail in a
simple manner and to be aligned in parallel thereto. The
coupling heads and ng openings are aligned along the
guide axis and can therefore be shifted along the guide axis
until they can be d and anchored into one another.
In addition or alternatively the diameter of the guide rail is
selected smaller than the er of the mounting rail, so
that the guide rail can be inserted into the mounting rail and
can axially be shifted. Hence, this process for coupling and
decoupling the guide rail is done under guidance and can
easily be performed by the ler.
The coupling head can be connected to the guide rail or to the
mounting rail in any suitable manner. Preferably the coupling
head or its coupling neck is screwed, moulded or d.
E.g., the coupling neck is guided through a related opening in
the guide rail or the mounting rail so far that an edge
extends beyond the opening, which is connected by a press fit
stem process and is cally deformed to a flange element,
in order to establish a force-locking and form-locking
connection. The coupling neck preferably comprises a flange
element, preferably a flange ring, which abuts the other side
of the central member of the guide rail or the mounting rail,
which is therefore clamped between the formed flange element
HAWA 16-01 EP / 06.04.17
and the flange ring. The coupling head can also be mounted
with a screw, which is for example axially held in an inner
thread of the coupling neck and which abuts with the screw
head the central member of the guide rail or the mounting
rail. Alternatively, the coupling neck itself can be provided
with a thread, which is turned into an opening in the guide
rail or the mounting rail, in which a thread or a threaded
element is inserted.
The coupling head can rotation symmetrically be constructed
and can be mounted in a simple manner. Alternatively, at the
d side a segment of the coupling head or the coupling
plate, respectively, can be cut away, so that the coupling
plate cannot engage in the mounting rail when dismounting. By
a suitable design of the coupling head an additional ramp may
not be required.
In a further red ment a buffer device is provided
that comprises the at least one ramp and/or at least one
resilient element, with which, after connecting the guide rail
to the mounting rail, the coupling head is cally coupled
to the central member of the guide rail or the central member
of the mounting rail. Thereby any play between the mounting
rail and the guide rail is avoided. By the buffer device,
which is preferably made from plastic, a direct contact
n the guide rail and the mounting rail and therefore
metallic noise is avoided, when the sliding door is operated.
The buffer device preferably comprises a plate-shaped member
with an opening, which serves for receiving the coupling neck
of a ng head. Thereby, the buffer device can be
connected to the coupling head such that the resilient
ts or spring elements are arranged laterally adjacent to
the coupling head and/or the ramps are arranged aligned along
HAWA 16-01 EP / 06.04.17
the guide axis on the front side and the backside of the
ng head.
The at least one resilient t and/or the at least one
ramp or preferably connected in one piece to the buffer
. Alternatively, the resilient element and/or the ramp
can be connected e.g. by means of a snap-on or click
connection in a form-locking manner to the buffer device.
The at least one resilient element and/or the at least one
ramp are preferably d in parallel to the guide axis, so
that they exhibit optimal mance during mutual
displacement of the guide rail and the mounting rail and are
exposed to pressure only, but not torsion.
In a further preferred embodiment the coupling head comprises
a central bore, through which a fixing element, such as a
screw, can be guided, e.g. in order to fix the guide rail or
the mounting rail, electrical devices, such as power supply
lines for motorised carriages, etc..
The coupling head is preferably held torque proof in the
related central member, so that it cannot automatically get
loose from the central member. In a particularly simple manner
this can be done by providing the coupling neck and the
thereto corresponding opening in the central member of the
guide rail or the mounting rail with a nal crosssection.
Alternatively a locking device can be used. E.g., the
buffer device is ted torque proof with the related
central member and torque proof with the coupling head and is
provided for this purpose with locking elements, which are
connectable in a form-locking manner to the guide rail and to
the coupling head. The connection between the buffer device
and the coupling head is advantageously established with the
inventive ramp, which engages in a form-locking manner into a
HAWA 16-01 EP / 06.04.17
recess provided in the coupling head, and with holding
elements, which are connectable in a form locking manner to
the guide rail or to the mounting rail.
The coupling head and/or the buffer device are preferably made
of metal or plastic, preferably rigid plastic. Preferably a
thermoplastic plastic, such as Polyoxymethylen (POM), is used,
which exhibits high strength, stiffness and good sliding
properties.
The buffer device can consist of an elastomer or natural
rubber, which is preferably provided with a coating, which
provides the surface of the buffer device with excellent
sliding properties and which facilitates mounting of the
rails.
Alternatively, between the coupling head and the buffer device
optionally a sound absorbing element can optionally be
uced, which consists of an elastomer or natural rubber
and provides improved sound ling n the mounting
profile and the guide rail. The for example annular sound
absorbing element can be several times softer than the
al of the buffer device.
In a further preferred embodiment the coupling opening adjoins
a coupling l, which is delimited by the central member
of the guide rail and coupling strips, which are distant from
the l member and which are held within the guide rail in
parallel to the central member facing one r and which
are connected each to a side member of the guide rail. Hence,
the coupling plate can be inserted through the coupling
opening into the coupling channel and can there be held
preferably by the resilient elements without play.

gs 61 to the carriages 63 provided in the guide rail 1A.
Fig. 1b shows as an example that the sliding door 6 has been
ctured from wood and has been ed with recesses 60
at the upper corners. Into the recesses 60 a door fitting 61
has been inserted that comprises a fitting rail 611 and
g block 612 shifted therein. The fitting block 612 is
connected via a threaded bar 62 to the related carriage 63,
that comprises wheels 631, which can run each on rail foots 13
provided on both sides of the guide rail 1A. Hence, the
carriages 63 and the sliding door 6 are displaceable along a
guide axis x and can be driven into the parking space 7. As
mentioned, the guide rail 1A has partially been cut away, in
order to show the carriage 63 and the door fitting 61.
Fig. 1c shows the rail device 10A that has been removed from
the sliding door system of Fig. 1a and of which the proximal
quarter has been cut away in order to completely show the
coupling devices, which comprise coupling heads 3A connected
to the mounting rail 2A and coupling openings 4A provided in
the guide rail 1A. The coupling heads 3A, which can be
anchored in the coupling openings 4A, will be described in
detail below.
The guide rail 1A comprises a U-profile that is opened
downwards and at comprises a central member 12, which is
HAWA 16-01 EP / 06.04.17
adjoined on both sides by side members 11, which form together
with foot members 13 that are facing one another an L-profile
each. The side s 11 are further connected via fillets to
a flange plate 111 that is aligned in parallel to the side
members 11.
The ng rail 2A comprises an H-profile with a central
member 22 that is adjoined on both sides by side members 21.
The distance between the side members 21 of the mounting rail
2A is larger than the distance between the side members 11 of
the guide rail 1A, but smaller than the ce between the
flange plates 111 of the guide rail 1A.
As shown in Fig. 2a, between each flange plate 111 and the
related side member 11 a coupling space 110 is provided, in
which the d side member 21 of the mounting rail 2A can
enter. The flange plates 111 overtop the central member 12 of
the guide rail 1A at the upper side and therefore facilitate
coupling to the installed mounting rail 2A.
Below the l member 12 of the guide rail 1A the coupling
openings 4A are adjoined by a coupling channel 15 that is
partly delimited by the central member 12 of the guide rail 1A
and by two coupling strips 16, which are facing one another on
even height and are connected each with one of the side
members 11. A space is kept open between the coupling strips
16 that allows a tool to enter the coupling channel 15.
The coupling head 3A is held preferably torque proof in an
g 28, e.g. screwed, press fitted, welded or d.
Fig. 2b shows the rail device 10A of Fig. 1c after connecting
the guide rail 1A to the mounting rail 2A. The coupling plate
32 of the coupling head 3A has been inserted into the coupling
channel 15 and the central member 12 of the guide rail 1A is
held between the side members 21 of the mounting rail 2A.
Hence, the guide rail 1A is movable only in parallel to the
guide axis x or in parallel to the longitudinal axis of the
HAWA 16-01 EP / 06.04.17
rail device 10A. This facilitates the process of coupling and
decoupling the guide rail 1A from the coupling heads 3A of the
mounting rail 2A.
Fig. 3a shows one of the coupling heads 3A of Fig. 1c. Fig. 3b
shows the coupling head 3A of Fig. 3a cut along line A—A. Fig.
3c shows the ng head 3A of Fig. 3a from below. Fig. 4
shows a part of the rail device 10A of Fig. 1c in spatial view
with a cart along the longitudinal axis of the mounting rail
The coupling head 3A comprises a coupling neck 31, which
comprises a connecting member 311 and a spacer portion 312.
The ting member 311, which has a small er than the
spacer portion 312, is formed as an octagon and fits into a
corresponding octagonal opening 28 provided in the central
member 22 of the mounting rail 2A. After insertion into the
octagonal opening 28 the upper side of the spacer portion 312
forms a flange ring which adjoins the lower side of the
central member 22. The upper end piece 310 of the ting
member 311 projects then out of the octagonal opening 28 (see
Fig. 9) and can be caulked, i.e. plastically deformed, so that
the connecting member 311 is held, below by the spacer portion
312 and above by the press fitted end piece 310, axially
immovable in the octagonal opening 28. By the nal form
of the connecting member 311 and the opening 28 the connecting
member 311 and therefore the complete coupling head 3A is also
held torque proof.
The coupling neck 31 is adjoined by a round coupling plate 32,
which is designed for entering the coupling channel 15 (see
Fig. 4). Fig. 3b shows, that an axial bore traverses the whole
coupling head 3A, which can be manufactured with an inner
thread.
Fig. 4 shows the coupling opening 4A that is provided in the
central member 12 of the guide rail 1A and that comprises a
larger first opening part 41 and a smaller second g part
HAWA 16-01 EP / 06.04.17
42. The size of the larger opening part 41 is d to the
coupling plate 32, which can be transferred at this position
through the coupling opening 4A into the coupling channel 15.
uently the guide rail 1A can be shifted relative to the
mounting rail 2A and can be anchored therein. Thereby second
opening part 42 receives the spacer portion 312 preferably
without play. However, the coupling plate 32 is held below the
second opening part 42, whose bordering edges form a holding
flange. Hence, the guide rail 1A is connected to the mounting
rail 2A and can only be released by shifting the first opening
part 41 back over the coupling plate 32. Into a further
opening 18 in the guide rail 1A a bolt or a fixing screw 91
can be inserted, in order to lock the ed guide rail 1A
relative to the mounting rail 2A.
In order to hold the anchored guide rail 1A without play at
coupling head 3A, preferably one or more resilient elements,
preferably spring ts, such as leaf springs, are
provided.
ing to the ion, in order to facilitate removal of
the coupling head 3A out of the coupling opening 4A, at least
one ramp is provided, which adjoins the coupling head 3A.
The at least one resilient element and/or the at least one
ramp can be connected in one piece to the coupling head 3A or
can be moulded thereto in one piece. Preferably a buffer
device is provided, which comprises the at least one resilient
element and/or the at least one ramp.
Fig. 5a shows the coupling head 3A of Fig. 3a with a buffer
device 5A ted thereto, which comprises spring elements
51 on both sides and a ramp 52 on the front side and the
backside each. Fig. 5b shows the coupling head 3A of Fig. 5a
with the buffer device 5A connected thereto from below.
Fig. 6a shows the buffer device 5A of Fig. 5a from above and
Fig. 6b shows the buffer device 5A of Fig. 6a from below.
HAWA 16-01 EP / 06.04.17
The buffer device 5A consists of a rectangular buffer plate
50, which comprises an opening 500 in the centre, which serves
for receiving the coupling neck 31 of the coupling head 3A, as
shown in Fig. 5a. On opposite sides the buffer plate 50
comprises resilient elements that are directed downwards or
spring elements, respectively, in the form of leaf springs
that are held on both sides. The spring elements 51 are formed
from the buffer plate 50 and are aligned in parallel to one
another. atively, the spring elements 51 can also be
held on one side only. At the lower side, the buffer plate 50
is provided at the front side and the backside each with a
ramp 52, which both, seen from below, increasing height in
ion towards the opening 500.
Fig. 5a shows that the spring elements 51 and the ramps 52 of
the ng plate 32 are directed towards the coupling head
3A, so that they can interact with the central member 12 of
the guide rail 1A held by the coupling head 3A or with the
bordering edge surrounding the coupling opening 4A of the
central member 12.
Fig. 7 shows the rail device 10A of Fig. 4 with the buffer
device 5A of Fig. 5a set up on the coupling head 3A. The
buffer plate 50 adjoins the central member 22 of the mounting
rail 2A and the spring elements 51 and the ramps 52 provided
at the buffer plate 50 extend towards the central member 12 of
the guide rail 1A. In order to show the installed coupling
head 3A with the buffer device 5A the mounting rail 2A is cut
along its longitudinal axis.
Fig. 8a shows the rail device 10A of Fig. 7 with the guide
rail 1A ted from the mounting rail 2A. Fig. 8b shows the
rail device 10A of Fig. 8a after the guide rail 1A has been
coupled to the ng rail 2A. The buffer plate 50 is held
above the central member 12 of the guide rail 1A and presses
the guide rail 1A with the nonvisible spring elements 51
without play against the ng plate 32 of the coupling
HAWA 16-01 EP / 06.04.17
head 3A, which is held by means of the coupling strips 16
within the coupling channel 15.
Fig. 9a shows in spatial new a part of the rail device 10A of
Fig. 8b with a cut along the longitudinal axes of the guide
rail 1A and the mounting rail 2A. It can be seen that the,
polygonal or preferably octagonal ting member 311 of the
coupling neck 31 is held torque proof in the polygonal or
preferably octagonal opening 28 within the central member 22
of the mounting rail 2A drehfest. The upper end piece 310 of
the connecting member 311 of the coupling neck 31 projects
beyond the central member 22 of the mounting rail 2A and can
be deformed by caulking into a flange t. The buffer
plate 50 of the buffer device 5A adjoins the lower side of the
central member 22 of the mounting rail 2A and presses with the
spring elements 51 against the upper side of the central
member 12 of the guide rail 1A. The coupling plate 32 of the
coupling head 3A has been transferred through the coupling
opening 4A into the coupling channel 15 and lies above the
coupling strips 16. The ramps 52 are aligned in parallel to
the rail axis and t the coupling plate 32 from being
driven on the front side or the backside below the edge of the
central member 12 of the guide rail 1A. The coupling plate 32
lies still below the first g part 41 and will be placed
below the second opening part 42 of the coupling opening 4A
and anchored there by shifting the guide rail 1A in the
direction indicated by an arrow. Through the opening 18 in the
guide rail 1A a lock element can be guided against the
mounting rail 2A.
Fig. 9b shows the part of the rail device 10A of Fig. 9a with
a cut along the longitudinal axis of the ng rail 2A and
a cut h the proximal left corner of the buffer device 5A
of Fig. 5a. Hence, the left ramp 52 is shown in sectional view
and the left side of spring element 51 has been cut away. It
is shown that the ramp 52 adjoins the lower side of the
coupling plate 32 of the ng head 3A, i.e. the side
facing the coupling neck 31. In this preferred embodiment, the
HAWA 16-01 EP / 06.04.17
height h52 of the ramp 52 therefore corresponds approximately
to the height h31 of the coupling neck 31, and is therefore
smaller than the height h3A of the coupling head 3A.
The ramp 52 has a front face 521 that is ed ve to
the guide axis x with an angle preferably in the range between
40° and 60° most preferably with an angle of imately
45°.
The front face 521 is preferably located outside the radius
r32 of ng plate 32 and preferably ends at least
approximately at the periphery of the coupling plate 32.
Hence, the front face 521 extends from the endpoint of radius
r32 of coupling plate 32 to the endpoint of radius r52 of the
buffer device 5A each measured from a central axis y of the
coupling head 3A in a direction in parallel to the guide axis
x.
Fig. 10a shows the rail device 10A of Fig. 9 with the coupling
head 3A anchored in the second opening part 42 of the coupling
opening 4A. The front sided ramp 52 of the buffer device 5
abuts the edge of the coupling g 4A and prevents the
coupling plate 32 to move along the guide axis X below the
central member 12 of the guide rail 1A.
Fig. 10b shows the rail device 10A of Fig. 10a with the
coupling head 3A shifted into the first opening part 41 of the
coupling opening 4A. In this position the back sided ramp 52
abuts the edge of the coupling opening 4A and prevents the
coupling plate 32 to move along the guide axis X below the
l member 12 of the guide rail 1A. When moving the guide
rail 1A the coupling head 3A is released from anchorage in the
second opening part 42 of the coupling opening 4A and 58 into
the first opening part 41, whereafter the guide rail 1A can be
removed, without the risk that the coupling plate 32 could
engage in the central member 12 of the guide rail 1A.
HAWA 16-01 EP / 06.04.17
Fig. 11 shows an inventive rail device 10B in a second
preferred ment. The proximal quarter of the rail device
10B has been cut away to show the elements of the coupling
devices, which comprise coupling heads 3B that are connected
to the guide rail 1B and stand will be anchored in coupling
openings 4B provided in the ng rail 2B.
The guide rail 1B is shown in a r embodiment and
comprises a central member 12 ed by side members 11 on
both sides, which form together with a foot member 13 each an
L-profile. On the l member 12 the coupling heads 3B are
arranged and held torque proof.
The mounting rail 2B comprises a U-profile that is opened
downwards and that comprises a central member 22 with the
coupling openings 4B. On both sides of the central member 22
side members 21 are provided, whose mutual distances larger
than the mutual distance of the side members 11 of the guide
rail 1B. Hence, the guide rail 1B can be received in the U-
profile of the mounting rail 2B, whereby the coupling of the
guide rail 1B to the mounting rail 2B is facilitated.
The ng openings 4B provided in the central member 22 of
the mounting rail 2B correspond to the coupling openings 4A in
the guide rail 1A as shown e.g. in Fig. 4 and comprise also a
larger first opening part 41 and a r second opening part
42 which form approximately a keyhole. The first opening part
41 is for example circular and the second opening part 42 is
elongated or at least approximately rectangular and preferably
rounded. The coupling of the guide rail 1B to the mounting
rail 2B is done in the same way as described above, merely the
coupling devices are mounted invers in the rail device 10B,
wherefore a kinematic ion is present.
Fig. 12a shows one of the coupling heads 3B of Fig. 11 and a
buffer device 5B connected thereto, which also is provided at
the front side and the backside each with a ramp 52 and on
both sides with spring elements 51. Fig. 12b shows the
HAWA 16-01 EP / 06.04.17
coupling head 3B and the buffer device 5B cut along line B--B
shown in Fig. 12a. Fig. 12c shows the coupling head 3B and the
buffer device 5B of Fig. 12a in explosion view.
As shown in the preferred embodiment of Fig. 10b, the ramps 52
connected to the buffer device 5B prevent the coupling plate
32 of the coupling head 3B from engagement in the central
member 22 of the mounting rail 2B when nting and moving
the guide rail 1B along the guide axis X.
In addition, the ramp 52 serves for holding the coupling head
3B torque proof. For this purpose, the buffer device 5B
comprises holding elements 55 on both sides, which embrace the
central member 12 of the guide rail 1B on both sides and
therefore hold the buffer device 5B and the ramps 52 torque
proof. The ramps 52 each extend into a holding groove 321
provided in the ng plate 32 of the coupling head 3B,
whereby the coupling head 3B is firmly coupled to the guide
rail 1B and held torque proof.
Fig. 12a and Fig. 12b show, that the spring elements 51 are an
integral part of the buffer plate 50 and are slightly curved
towards the coupling plate 32.
Fig. 12b shows, that between the coupling plate 32 of the
coupling head 3B and a support plate 58 of the buffer device
5B optionally an elastic damping element 59 is provided, which
has an annular shape and ts of elastic plastic material.
The t plate 58, the damping element 59 and the coupling
plate 32 form a unity and are transferred as a unity through a
d ng opening 4B in the central member 22 of the
mounting rail 2B and are anchored as shown in Fig. 13.
The coupling neck 31, which has been guided through an opening
500 in the damping element 59 and in the support plate 58,
ses an inner thread, in which a mounting screw 93 is
turned. By means of the mounting screw 93 the coupling head 3B
HAWA 16-01 EP / 06.04.17
and the buffer device 5B are screwed to the central member 12
of the guide rail 1B.
Fig. 13a shows the rail device 10B of Fig. 11 with the guide
rail 1B separated from the mounting rail 2B. The guide rail 1B
is connected to the coupling head 3B and the buffer device 5B
by the ng screw 93.
Fig. 13b shows the rail device 10A of Fig. 13a after the guide
rail 1B to the mounting rail 2B. The guide rail 1B has been
lifted and, after the transfer of the coupling head 3B through
the first opening part 41 of the coupling opening 4B, has been
shifted in parallel to the guide axis x, whereby the coupling
neck 31 of the coupling head 3B has been transferred into the
second opening part 42 of the coupling g 4B and
anchored.
In this position the ent elements 51 (not e) abut
the lower side of the central member 22 of the mounting rail
2B and at the upper side of the mounting rail 2B, above the
second opening parts 42, the coupling unit is held, which
consists of the support plate 58, the damping element 59 and
the ng plate 32. Hence, coupling plate 32, which is
screwed to the central member 12 of the guide rail 1B, is
separated by the resilient element 59 from the support plate
58, which adjoins the central member 22 of the mounting rail
2B. Hence, the mounting rail 2B is elastically held from above
by the damping element 59 and from below by the spring
elements 51 and is ore decoupled from the guide rail 1B.
Hence, noise that is caused by the carriages 63 when moving
the sliding door 6 will not be transferred from the guide rail
1B to the mounting rail 2B and the building.
Fig. 14 shows the guide rail 1B of Fig. 11 with two installed
coupling devices 3B that are ed each with a modified
buffer device 5B*. A cut has been made along the symmetry axis
through the rear part of the guide rail 1B and through the
rear coupling device 3B. The buffer device 5B* again comprises
HAWA 16-01 EP / 06.04.17
a buffer spring 51 and a buffer ramp 52, which serve for the
purposes described above. However, only one holding element 55
is provided, which in the form of a spine is held in an
g 121 provided indie central member 12 of the guide rail
1B. Holding elements, which laterally extend the guide rail
1B, can be avoided.
