In Figure 1 the track 13 is cut to half the short area A vertically, in order to represent the position of the two drive carriage 5 in the guide rail 13.

Between the two drive carriage means for closing the sliding door 1 reference numeral 19 is 5 (4 figfig.) .the device comprises in the example 19 visible a U - shaped housing 21. The housing 21 is shown in Figures 1 to 3 cut in sections represented, an unobstructed view of the pulleys 23 with the housing

Pulleys to allow battery 25. The rope reel body 23 is shown in Figure 7. The pulleys 23 together with a battery housing comprises pulleys 25, which is mounted on a shaft 27 in the side walls of pulleys rotatably housing 23, a clamping means, for example a clamping screw 29, for clamping the first end of a traction wire can be fixed on the two side walls of the pulleys 23 housing further 31st random web or felt pad 33 -, which project slightly beyond the side faces. The width b of the pulleys is increased by the two felt pad 33 housing 23.

From Figure 6 is apparent, that the pulleys 23 housing 25 in the housing 21 of the device with the pulleys battery is laterally guided and supported slidably on the ground both down. The two felt pad 33 effect, that the pulleys 21 of the device housing is mounted in the housing 23 play laterally displaceable. For reduction of the sliding resistance can on the underside of the

Pulleys 23 housing also felt or the like

be fixed. Upon displacement of the device 19 in the guide rail 13 are prevented noise therefore substantially. The device 19 or their housing 21 may carry at its front, in Figures on the left end, a roller 35, whose periphery is radially elastically formed, e.g. a rubber coating or a rubber ring bears. The roller 35 is rotatably mounted laterally of the housing 21. The

Rotational movement of the roller 35 is braked by suitable means, for example a rotary damper with a freewheel. The lateral arrangement of the roller 35 is selected such, that their periphery, which projects beyond the housing 21 slightly below, the horizontal limb 15 on the

Guide rail 13 frictionally rests.

A coupling element on the housing 21 of the device 19 is further at least at its left end 37 formed, with which the device 19 with the left thereof arranged drive carriage 5, 11 in the vicinity of the side edge of the

On the pulleys in the displaceable 25 batteries

Pulleys 23 and a second substantially identical pulleys battery housing 43, which is mounted on the rear end (right side in Figures) on a shaft 45, the traction cable 31 is guided. For this purpose in the two pulleys are three batteries 25, 43, for example.

Pulleys arranged side by side, with circumferential recesses 47. The depth of the recesses 47 are such

dimensioned, the traction cable laid in these 31 that a

Periphery of the pulleys does not protrude, i.e. protected within the recesses 47 is guided. For example three pulleys are preferably each mutually spaced apart, so that they can rotate independently at different speeds.

The one end of the traction wire 31 is attached to the pulleys housing 23. The other end is guided out of the apparatus 19 and fixed to the left end of the guide rail 13 with suitable means, e.g. a clamping screw, . The clamping screw is not represented of better clarity.

Retaining element 49 be provided, which is fastened to the front, left end of the guide rail 13 at this. The retaining member 49 comprises a resilient

Retaining lever or - shoe 51, which can impact of latching the door in a closed position (see Figure 1) drive carriage 3 and consequently the sliding door 1 in the

retaining closed position.

The sliding door 1 by a spring element, in particular one or more coil springs 53 into the end position

(1 closed sliding door) drawn. The tension spring 53, which engages on the one hand pulleys housing 23 and secondly to the front end of the housing 21 is, pulls the two pulleys 25 and 43 apart and shorten the free end of the batteries 31 traction wire, which is connected to the front end of the guide rail 13. The operation of the device 19 will be described below in more detail.

1 Figfig. assumed), which is, positioned if present, by a retaining lever 51 in the closed position from a closed sliding door 1, (. After overcoming the holding force of the holding lever 51 by manually pushing the sliding door in the direction of the arrow P is (1 figfig.) + 1, the tension spring 53 is tensioned in the apparatus 19, because the

23 housing displaceable pulleys by exhaustion of

Rope material, which is between the two pulleys 43 and stored batteries 25, the two pulleys closer together and thereby the tension spring 53 pulls apart 25.43 batteries. The opening of the sliding door 1 is therefore connected with a force, which is greater, than the force to overcome the rolling resistance of the two drive carriage when the sliding door 1 is in completely open position i.e. 5th, very law in figfig. 2, the sliding door 1 will in turn by a second

Retaining lever 51 secured to a retaining member 49. The two retaining elements 49 at the ends of the

Guide rail 13 are preferably formed identical.

Again to close the sliding door 1, must as with

For now open the retaining force of the holding lever 51 arranged right be overcome. This is done, the previously tensioned tension spring upon opening 31 from the two pulleys 25 and 43 draws the cable running on batteries 31. Consequently the run of the traction wire 31, which leads to the left end of the guide rail 13 and, e.g. on is

Retaining member 49, arranged fixed there, and the sliding door 1 drives left retracted. The damper braked by roller 35, sliding in the sliding door 1

Substantially constant speed will also decrease the stored energy in the left and as a result at the end of the travel movement slower and the tension spring 31

Retaining lever 51 held. Without the damper roller 35, the driving speed of the sliding door 1 dampens the latter would, speed up and against the left side

Retaining element 49 impinging.
