DETAILED DESCRIPTION
(29) FIG. 1a shows an inventive sliding door system with a parking space 7, into which an inventive rail device 10A is extending, which comprises a mounting rail 2A and a guide rail 1A releasably connected thereto. The front part of the guide rail 1A outside a parking space 7 is cut away, so that the carriages 63 are visible, which are guided in the guide rail 1A and which are connected via door fittings 61 to a sliding door 6. The parking space 7 is delimited on both sides by room walls 71, 72 that have been firmly installed after installation of the mounting rail 2A and that are removable only with considerable effort. Manual intervention into the room opening 70 of the parking space 7 after the installation of the room walls 71, 72 is no longer possible.
(30) The mounting rail 2A had been installed at the room ceiling in predetermined height and in horizontal alignment by means of mounting screws 91.
(31) Subsequently the carriages 63 and optionally a stopper device (not shown) have been inserted in the guide rail 1A, which then has been connected by inventive coupling devices to the mounting rail 2A. Finally, the sliding door 6, e.g. a glass door or a wooden door, has been connected by means of door fittings 61 to the carriages 63 provided in the guide rail 1A.
(32) FIG. 1b shows as an example that the sliding door 6 has been manufactured from wood and has been provided 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 fitting 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.
(33) 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.
(34) The guide rail 1A comprises a U-profile that is opened downwards and at comprises a central member 12, which is 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 members 11 are further connected via fillets to a flange plate 111 that is aligned in parallel to the side members 11.
(35) The mounting 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 distance between the flange plates 111 of the guide rail 1A.
(36) 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 related 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.
(37) Below the central 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.
(38) The coupling head 3A is held preferably torque proof in an opening 28, e.g. screwed, press fitted, welded or moulded.
(39) 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 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.
(40) 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 coupling 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 2A.
(41) The coupling head 3A comprises a coupling neck 31, which comprises a connecting member 311 and a spacer portion 312. The connecting member 311, which has a small diameter 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 connecting 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 octagonal 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.
(42) 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.
(43) 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 opening part 42. The size of the larger opening part 41 is adapted to the coupling plate 32, which can be transferred at this position through the coupling opening 4A into the coupling channel 15. Subsequently 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 anchored guide rail 1A relative to the mounting rail 2A.
(44) In order to hold the anchored guide rail 1A without play at coupling head 3A, preferably one or more resilient elements, preferably spring elements, such as leaf springs, are provided.
(45) According to the invention, 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.
(46) 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.
(47) FIG. 5a shows the coupling head 3A of FIG. 3a with a buffer device 5A connected thereto, which comprises spring elements 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.
(48) 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.
(49) 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. Alternatively, 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 direction towards the opening 500.
(50) FIG. 5a shows that the spring elements 51 and the ramps 52 of the coupling 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.
(51) 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.
(52) FIG. 8a shows the rail device 10A of FIG. 7 with the guide rail 1A separated 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 mounting 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 coupling plate 32 of the coupling head 3A, which is held by means of the coupling strips 16 within the coupling channel 15.
(53) 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 connecting 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 element. 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 prevent 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 opening 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.
(54) FIG. 9b shows the part of the rail device 10A of FIG. 9a with a cut along the longitudinal axis of the mounting rail 2A and a cut through 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 coupling head 3A, i.e. the side facing the coupling neck 31. In this preferred embodiment, the 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.
(55) The ramp 52 has a front face 521 that is inclined relative to the guide axis x with an angle preferably in the range between 40 and 60 most preferably with an angle of approximately 45.
(56) The front face 521 is preferably located outside the radius r32 of coupling 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.
(57) 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 opening 4A and prevents the coupling plate 32 to move along the guide axis X below the central member 12 of the guide rail 1A.
(58) 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 central 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.
(59) FIG. 11 shows an inventive rail device 10B in a second preferred embodiment. 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 mounting rail 2B.
(60) The guide rail 1B is shown in a simpler embodiment and comprises a central member 12 adjoined by side members 11 on both sides, which form together with a foot member 13 each an L-profile. On the central member 12 the coupling heads 3B are arranged and held torque proof.
(61) 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.
(62) The coupling 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 smaller 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 inversion is present.
(63) 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 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.
(64) As shown in the preferred embodiment of FIG. 10b, the ramps 52 connected to the buffer device 5B prevent the coupling plate of the coupling head 3B from engagement in the central member 22 of the mounting rail 2B when dismounting and moving the guide rail 1B along the guide axis X.
(65) 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 coupling plate 32 of the coupling head 3B, whereby the coupling head 3B is firmly coupled to the guide rail 1B and held torque proof.
(66) 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.
(67) 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 consists of elastic plastic material. The support plate 58, the damping element 59 and the coupling plate 32 form a unity and are transferred as a unity through a related coupling opening 4B in the central member 22 of the mounting rail 2B and are anchored as shown in FIG. 13.
(68) The coupling neck 31, which has been guided through an opening 500 in the damping element 59 and in the support plate 58, comprises an inner thread, in which a mounting screw 93 is turned. By means of the mounting screw 93 the coupling head 3B and the buffer device 5B are screwed to the central member 12 of the guide rail 1B.
(69) 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 mounting screw 93.
(70) 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 opening 4B and anchored.
(71) In this position the resilient elements 51 (not visible) 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 coupling 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 therefore 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.
(72) FIG. 14 shows the guide rail 1B of FIG. 11 with two installed coupling devices 3B that are provided 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 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 opening 121 provided indie central member 12 of the guide rail 1B.
