The invention resides an installation adjustment arrangement for an auto-return arrangement.
Auto-return arrangements generally need to be adjusted for example after installation of a sliding door in that the most suitable position of the stationary carrier is determined by trial settings.
It is the object of the present invention to provide a device for the rapid adjustment of the auto-return arrangement.
In an installation adjustment device includes a support rod with a front-end abutment surface and a slide member which is guided by the support rod so as to be stepwise position adjustable thereon. The slide member comprises an alignment surface which is arranged parallel to the abutment surface, so that the vectors normal to the abutment surface and the alignment surface have the same direction.
The invention will become more readily apparent from the subclaims and the following description of schematically shown exemplary embodiments.
The drawings show in:
The lower door fitting 40 includes a support roller 43. In the longitudinal direction 25 of the sliding door 20 ahead of, and behind, the support roller 43 cleaning brushes 44 are arranged. In the lower door fitting 40, furthermore an acceleration and deceleration device 45 is arranged. It comprises a carrier element 46 which is movable between a force- and/or form locking fixed park position and an end position. The carrier element 46 is connected to an acceleration arrangement and, parallel therewith, a deceleration arrangement. During movement of the carrier element 46, the force resulting from combined forces of the acceleration arrangement and the deceleration arrangement is effective on the carrier element 46. After release from the fixed park position, in the exemplary embodiment, the movement of the carrier element 46 is continued by a spring energy store being discharged while being slowed down by a cylinder-piston unit.
For example, during closing of the sliding door 20 before the sliding door 20 reaches the closed end position, the carrier element 46 comes into contact with a stationary carrier 51, see
In the representation of
The assembly assisting device 80 comprises a support rod 81 and a slide 91 which is movable along the support rod 81. The support rod 81 consists in the exemplary embodiment of a plastic material and has an essentially rectangular cross-section. One of the front surfaces which extend normal to the longitudinal direction 85 of the assembly assisting device 80 serves as stop surface 83. For example, at a distance from the stop surface 83, the support rod 81 is provided with a transverse stub 86 having a test surface 87. The transverse stub 86 projects in the exemplary embodiment normally from the narrow side 84 of the support rod 81. The projection length of the transverse stub 86 corresponds for example to one and a half times the width of the support rod 81. The distance of the stop surface 83 from the test surface 87, which extends parallel to the stop surface 83, is in the exemplary embodiment 67 millimeter. The vectors oriented normal with regard to the stop surface 83 and the test surface 87 point in the same direction.
At its narrow sides 84, the support rod 81 is provided with a plurality of stop notches 88. The notches formed in the two narrow sides 84 are displaced relative to one another. The individual notches 88 may be provided on the support rod 81 with markings.
The slide 91 extends around the support rod 81 to some extent. Its length is for example eight times the width of the support rod 81. The slide has two slide tongues 92 adjacent the two narrow sides 84 of the support rod 81. Both slide tongues 92 are flexible. They are provided with engagement tips 93 projecting toward the support rod 81.
The slide 91 is provided with an adjustment wedge 94 which projects from one side of the slide. The adjustment wedge 94 is oriented in the same direction as the transverse stub 86. The length of the projecting area corresponds for example to twice the width of the support rod 81. The adjustment wedge 94 includes an adjustment surface 95 which is oriented normal to the longitudinal direction 85 of the assembly assisting device 80. The vectors normal to the adjustment surface 95 and to the stop surface 83 extend parallel and point in the same direction.
Before the installation of the sliding door 20 in the door frame part 10, the position of the carrier element 46 relative to the door front surface 26 is determined by means of the assembly assisting device 80. In this step, the test surface 87 is brought into contact with the carrier element 46 when in the park position. Then the slide 91 is moved relative to the support part 81 until the adjustment surface 95 abuts the door front surface 26 of the sliding door 20. The adjustment surface 95 then abuts the vertical profile element 23. One of the engagement tips 93 of the slide 91 is then engaged in a stop notch 88 of the support rod 81. Depending on the design of the sliding door 20, the length of the vertical profile element 21 in the longitudinal direction may be different from that of other doors. With the same door fitting 40, then also the distance between the adjustment surface 95 and the test surface of the transverse stub 86 changes with the length of the vertical profile element 23 measured in the longitudinal direction.
Before or after the installation of the sliding door 20 into the door frame member 10, the position of the carrier 51 is adjusted. To this end, the installation assisting device 80 as adjusted in the previous step is placed onto the guide track 11 so that the stop surface 83 abuts the vertical door frame member 12. The lower carrier 51 is now so arranged that it abuts the adjustment surface 95. In this position, the carrier can be fixed.
The sliding door 20 as shown in
In
The positioning of the upper actuator 53 in this exemplary embodiment occurs in the same way as the lower carrier 51. After placement of the test surface 87 on the carrier element 65, the slide 91 is so adjusted that the adjustment surface abuts the door front surface 26. With the installation assisting device 80 so adjusted it is placed with the stop surface 83 into contact with the vertical door frame member 12. Now the actuator 53 is moved for example in a longitudinal guide structure 14 of the upper door guide track 13 until it abuts the adjustment surface 95. In this position, the actuator can be fixed.
With the upper auto-return arrangement 50, the actuator 53 can be position-adjusted before or after installation of the sliding door 20 in the door frame member 10.
In order to position, the actuator 53 for example the slide 91 is adjusted relative to the support part 81 so that an engagement tip 93 is engaged in that notch 88, which is marked for the particular vertical profile element 23. After abutment of the stop surface 83 on the vertical door frame member 12, the actuator is moved so as to abut the adjustment surface 95. At this point, the actuator can be fixed.
Upon closing or upon opening the sliding door 20, the stationary carriers 51, 54 come into contact with the carrier elements 46, 65 and release them from the arrest position. The sliding door is braked down and is moved slowly into the closed or the open end position. Here, it comes to a standstill without any contact noise.
Also, combinations of the individual various exemplary embodiments are possible.
