RUNNING TRACK DEVICE FOR THE DISPLACEABLE SUPPORT OF AT LEAST ONE FIRST ROLLER CARRIAGE AND AT LEAST ONE SECOND ROLLER CARRIAGE
A running track device for the displaceable support of at least one first roller carriage and at least one second roller carriage includes a first running track profile with a first roller running track for the displaceable support of the first roller carriage. The running track device further includes an attaching portion for the attachment to a wall above a door opening. A second running track profile is included having a second roller running track for the displaceable support of the second roller carriage and a mounting portion for the attachment of the second running track profile to a counter-mounting portion of the first running track profile.
1 . A running track device for the displaceable support of at least one first roller carriage and at least one second roller carriage ( 130 ), including a first running track profile with a first roller running track for the displaceable support of the first roller carriage and with an attaching portion for the attachment to a wall above a door opening, and including a second running track profile with a second roller running track for the displaceable support of the second roller carriage and with a mounting portion for the attachment of the second running track profile to a counter-mounting portion of the first running track profile.
2 . The running track device according to claim 1 , wherein the first roller running track is disposed parallel to the second roller running track and the first and second roller running tracks are disposed perpendicularly to the direction of movement of the roller carriages.
3 . The running track device according to claim 1 , wherein the first roller running track is configured to be approximately one third of the length less than the second roller running track.
4 . The running track device according to claim 1 , wherein the mounting portion and/or the counter-mounting portion includes a variation device for varying the distance perpendicularly to the direction of movement of the roller carriages, of the height difference along the direction of gravity and/or of the angle offset between the first roller running track and the second roller running track.
5 . The running track device according to claim 1 , wherein the mounting portion includes a mounting surface for the full contact at a counter-mounting surface of the counter-mounting portion.
6 . The running track device according to claim 5 , wherein the mounting surface and the counter-mounting surface are aligned along or essentially along the direction of gravity.
7 . The running track device according to claim 1 , wherein the second roller running track is disposed offset above the first roller running track having an offset distance ranging between 0.2 and 0.8 of the diameter of a rotatable bearing means of the second roller carriage.
8 . The running track device according to claim 1 , wherein a mounting means with a mounting axis, which is aligned parallel or essentially parallel to an axis of rotation of a rotatable bearing means, is employed for the attachment of the mounting portion to the counter-mounting portion.
9 . The running track device according to claim 1 , wherein the first running track profile and/or the second running track profile include/s a fixing portion for the attachment of a faceplate device for covering a second roller running track.
10 . The running track device according to claim 1 , wherein the second running track profile includes a running track faceplate portion for an at least partial covering of the first roller running track.
11 . The running track device according to claim 1 , wherein the first running track profile and/or the second running track profile are/is configured as an extruded profile.
12 . A sliding door installation including a running track device having the features of claim 1 , wherein at least one first roller carriage is supported to be displaceable on the first roller running track and at least one second roller carriage is supported to be displaceable on the second roller running track.
13 . A method for mounting a sliding door installation having the features of claim 12 , the method including the following steps:
attaching the first running track profile to a wall above a door opening by means of an attaching portion,
inserting the at least one first roller carriage onto the first roller running track,
attaching the second running track profile by means of the mounting portion to the counter-mounting portion of the first running track profile, and
inserting the at least one second roller carriage onto the second roller running track.
