EP1972594B1 - Elevator door sill with hidden guide - Google Patents

Abstract

The system has a door with two movably suspended, relatively telescopic door panels glided at the bottom by several mutually independent covered guides. It has a guide groove that is open only to the shaft that guides the lower end of a faster door panel, whilst another guide groove is open towards the floor of the story or cabin and guides the lower end of a slower door panel. An independent claim is also included for a door sill for an elevator door system.

Description

The invention relates to an elevator door system according to the preamble of claim 1.

Modern, designed as sliding doors elevator door systems consist of individual door panels, which are suspended on its upper side slidably in a guide rail. On the underside of such door panels run in another guide rail. This lower guide rail prevents the panels from being able to move laterally. As a rule, the lower guide rail is flush with the surface of the respective floor or elevator car floor and has guide grooves open towards the floor surface, in which corresponding guide shoes of the door panel intervene. Guide rails of this type always cause problems or problems. Because the upwardly open and accessible from the floor or car floor forth guide grooves pollute very easily. In addition, again and again foreign bodies (pebbles, cigarette butts and the like.) Treaded into the guide grooves or even fun or arrogance inserted into the guide grooves so that the guide shoes either Immediately jam in the guide rail or prematurely wear and then immediately become inoperative. In particular, foreign objects in the guide rails can cause the manhole or car doors no longer close completely and consequently can not be locked, whereupon the elevator goes to trouble. In addition, the upwardly open guide grooves are also a potential source of danger for narrow heels of women's shoes - as a result of carelessness, the paragraph can penetrate a little way into the guide groove whereby at least the paragraph is damaged. Incidentally, the upwardly open guide rail is also a weak spot where it depends on a robust design that offers some security against vandalism. Finally, upwardly open guide grooves also present problems where the elevator is often used to transport loads loaded on trolleys. Especially with heavily loaded cars it prepares because of their z. T. very small roles difficulties to push the respective car on the guide rail away in the cabin of the car in or out of her. In addition, the roles of such trolleys claim the upwardly open guide grooves z. T. very strong. Corresponding wear occurs.

It is therefore known to use so-called thresholds with concealed guide. These thresholds are characterized by the fact that their guide groove is open only to the shaft interior and not to the ground surface. For single-panel or double-panel doors, the panels of which open to the left and right, such a door sill eliminates the problems as much as possible.

For doors that consist of several door panels that open and close telescopically, the use of door sills with opened to the shaft interior guide leads to some effort. After all, the individual door panels must indeed be guided in the guide groove so that they can be driven one behind the other in the course of telescoping without the guide shoes coming into conflict with one another. It is known, for. B. from the Fig. 3 of the utility model DE 94 09 561 to provide for this purpose different degrees of cranked guide shoes. Since some of the door panels act here with a relatively long "lever arm" with respect to the guide rail, the guide shoes must be relatively rigid, ie made quite solid with increasing cranking.

Because of that, the DE 94 09 561 alternatively, only one of the three telescoping door panels in the open to the shaft inside guide groove to lead. This inner door panel carries on its outside in turn a guide rail in which the middle panel runs. In the same way, the middle and the outer panel are connected to each other. The outer panel in turn carries a guide rail, with which it runs on a dowelled to the shaft wall guide shoe. This quite complex construction requires some space, so a correspondingly deep door reveal. It also causes considerable installation effort - the wall-side guide shoe must be precisely aligned relative to the guide rail. This requires due to the customary, relatively large tolerances of the shaft wall an individual adjustment for each bay door of a construction site (eg., By appropriate documents between the wall-fixed guide shoe and the shaft wall). It is therefore not possible on the shaft side at least, the door system already factory pre-adjust completely. Also document JP 05 310 391 discloses a hinged door system.

It is an object of the invention to avoid the disadvantages known from the prior art.

This object is achieved in that a guide groove only opened to the shaft, d. H. is only accessible from the shaft and the lower end of a faster door panel leads, while another guide to the floor or car door out, so is open at the top, while the lower end of a slower door panel leads, this other guide only in such a Range up, d. H. is open to the floor or car floor, which is covered by the door leaves against direct access from the floor or car floor both closed and when the door is open, which is almost impossible that from the floor or car floor ago foreign body in the up open guide groove are introduced or fall into it or the upwardly open guide is manipulated.

A faster-running door panel is a door panel that, when viewed from the visible side, moves behind another door panel to open the door and therefore generally moves faster than this other door panel. A slower door panel is a door panel behind which, when the door is opened, one or more other door panels slide, which is why this one Door panel usually runs slower than the other door panels that have to cover another way. In individual, ie in each case by its own, completely independently operating drive moving door panels, the terms "faster" / "slower" apply mutatis mutandis.

With the invention it is achieved that all door panels are guided at their lower end of the threshold, without the risk that get from the floor or car floor of foreign matter in the upwardly open guide and interfere with the leadership. For the guide or guide grooves, which are open to the top, the floor or car floor, are open only in an area that is not directly accessible from the floor or car floor (ie for the users of the elevator) even with the doors open. Of course, the guide groove accessible from above or each of the grooves accessible from above may extend over the entire length of the door threshold. The decisive factor is that this groove or these grooves are driven exclusively in an area that is always outside the area accessible from the floor or car floor ago range. All sections of said groove or grooves, which are accessible from the floor or car floor when the door is open, can thus be closed by a corresponding cover. If the door sill is made as a milled part, it is of course also possible to provide this guide or guide only along sections of the door sill, where they are really needed.

A preferred embodiment is described by claim 2. With such a construction, the slowly running door panel is guided in an optimal manner, because it is not only guided directly in the threshold, but at the same time on the fast-running door panel, so that quickly and slowly running door panel form a direct connection. The same applies mutatis mutandis, provided three telescoping door panels are provided for the two slower-running door panels, etc.

Furthermore, the embodiment provided under claim 3 is ideal from a strength point of view. The fact that the guide shoes described by the dependent claim 3 for guiding a faster and a slower-running door panel at fully closed Door behind each other or directly next to each other, the slower-running door panel is supported in the overlapping area of the door panels on the shortest route over the faster-moving door panel on the door sill.

Also, the proposed by subclaim 6 preferred embodiment serves to increase the stability. The fact that the slower running door panel directly opposite the door sill supporting guide shoe is connected both directly to the door panel itself, as well as with the follower guide rail, a particularly stable leadership is achieved.

Favorable is also provided by claim 7 embodiment of the follower guide rail as a double U-profile or, equivalently, as a double C-profile. Such a trained guide rail can be produced efficiently by extrusion and is used with its upper U-profile section as a guide, while the lower U-profile section in a simple manner allows attachment. The same applies to the C-profile.

Ideally, a brush running in at least one guide groove of the guide rail is provided, which in particular is configured and dimensioned so that it can carry dirt out of the guide groove into the guide groove or moves it into an area in which the dirt does not interfere.

Another aspect is to provide a door sill which is structurally suitable for the use of the elevator door system according to the invention, which has a whole series of different functional areas, which can be produced rationally, preferably in one piece, and which is thus rigid, that it may optionally be used without a sub-threshold, resting freely on console-type supports. Such a door threshold contributes to the preferred embodiment which is protected by claim 8 et seq.

Continuous stiffening chambers, which maintain their stability by enclosing walls surrounding them and are preferably completely closed to other chambers, provide despite relatively thin wall thicknesses for a high stability of the profile.

If the guide grooves each provided by specially equipped guide chambers, as described in the dependent claim 10, then you get particularly pollution and play-insensitive guide grooves.

The proposed by claim 11 preferred embodiment of the guide provided in the guide surfaces as only one side tethered cantilever allows a particularly simple and precise production of the guide surfaces in the context of extrusion.

Further effects and embodiments of the invention are shown in the following embodiment.

The Fig. 1 shows a schematic representation of a view from the outside of the door area of an elevator car 1 - the invention will be explained with reference to a car door system. However, the same applies mutatis mutandis to shaft door systems.

The car door system here consists of two a kind of door frame (car door front) forming frame surfaces 2 for the front access of the car, two door panels 3 and 4 and a door sill 5. The door sill 5 is with their T-slots 20 b and c, at their in Fig. 1 attached left side, attached to the lower end edge of the elevator car. The two door panels 3 and 4 open to the left. They telescope, that is, the faster running door panel 3 comes (seen from inside the car) to lie in the open state behind the slower moving door panel 4. Due to this, the door threshold 5 also projects to the left into the shaft.

The Fig. 2 shows the same state of affairs, but not in perspective, but from the frontal.

As can readily be seen, the door panels 3 and 4 consist of simple sheets which have a smooth side towards the inside of the car and are folded over towards the outside of the car at their edges, which provides stability. In addition, in each case approximately in the center of the panel, on the door panels 3, 4, from the side facing away from their visible side, an approximately Ω-shaped reinforcing plate is dotted or glued, which results in a hollow stiffening channel in the assembled state. The door panels are also on their underside each provided with a mounting profile 3a and 4a, which serves with its plurality of slots each as a (variable) mounting base for the respective holding plates 3 b, 3 c and 4 b of the relevant guide shoes and will be explained later in more detail.

The door sill 5, whose design is to be discussed in more detail, here has two separate guide grooves 6 and 7. The guide groove 6 is in principle accessible from above, the guide groove 7 only from the side of the shaft interior ago.

The guide shoes of the fast-running door panel 3 are guided by the only accessible from the shaft inside guide groove 7, they are for this purpose by means of appropriately cranked mounting plates 3 b and 3 c outside the fast-moving panel 3 attached. The retaining plates carry at their lower end the actual guide shoe (in Fig. 1 and 2 not shown) and are height-adjustable bolted to the door panel 3.

The slow-moving door panel 4 is guided in a different way. It is equipped with a ride along it guide rail 9. This co-moving guide rail 9 is torsionally stiff screwed at its end facing the car side with a straight plate 4 b, which carries at its lower end a guide shoe which is guided in the upward, to the car floor open guide 6 (not for the elevator user visible area). In the other end of this traveling guide rail 9 engages a guide shoe, which is supported by a holding plate 3 d, which is screwed to the front side of the fast-moving door panel 3. The slowly running door panel 4 is therefore also guided in two places, namely on the one hand in the upwardly open guide groove 6 of the door sill 5 and the other on the fast-running door panel 3, which in turn is guided in two places in the door sill 5.

It is noticeable that the bent holding plate 3 b with its guide shoe and the retaining plate 3 d with its guide shoe (seen from the interior of the car) from approximately aligned, so are approximately behind each other or directly next to each other. This ensures that acting on the slowly running door panel 4 in the transition region to the fast-moving door panel 3 forces on short paths in the fast-moving door panel 3 and be derived from there directly into the guide rail - so that the fast-running door panel is hardly subjected to bending by the forces that are supplied to him from the slow-moving door panel. In this way, a fairly good stability is achieved.

The bolted to the narrow side of the door panel 3 retaining plate 3 d is preferably designed as a sheet metal bent part, as in Fig. 1 shown. It is punched out of a flat sheet and then bent several times. In this case, the vertically lying, perpendicular from the plane of the screw between the sheet and the door panel 3 projecting tabs supports the lower, horizontally lying portion of the holding plate 3 d against such forces from which have the tendency to bend the horizontal lying section upwards.

A decisive point is that this type of guidance makes it possible to cover the guide groove 6, which is open towards the top of the car floor, by means of preferably one-but also multi-part cover plates 12, specifically in the entire area which is accessible when the door is completely open. or car floor is released. In order to make this cover 12 flush with the surface of the car floor, the door sill 5 is offset by a corresponding amount down. Instead of a special cover plate z. As well as the building or car side anyway to be provided floor covering the guide rail overlap accordingly and act as a corresponding cover - a type of cover, in particular, no fluids through into the region of the guide rail in and also otherwise vandalismussicher.

The traveling guide rail 9 is designed as a double U-profile. The first, upwardly open U-profile serves as a guide rail for the guide shoe of the fast-moving door panel 3. The downwardly open door profile is used for easy, adjustable attachment of the moving guide rail 9. It is quite clear how the upper U-profile to his Has leg ends thickening, which form the actual, precise guide surfaces. This upper U-profile is designed so that below the actual guide surfaces enough space is available to possibly deposit deposited in the U-profile foreign body in harmless distance from the guide surfaces - For example, dirt or cement or plaster chunks that have penetrated in the course of the remaining completion of the building in this rail.

In particular, on closer examination of the Fig. 1 is easy to understand that the upward, to the floor or car floor open guide groove 6 is covered even with the door completely open by the door leaves against immediate access from above, from the floor or car floor. For a first part of the guide groove 6 is behind the door frame 2 and is also covered with the door open from above through the door panel 4, so it is practically inaccessible. The second, larger part of the guide groove 6 is even completely out of reach in the shaft. He is therefore, seen from the inside of the car, even more shielded by the door panel 4 before access from the car floor or floor of the floor.

The Fig. 3 shows a cross section of the door sill 5 as such. The door sill 5 is designed here as an extruded profile of an aluminum alloy (or wrought aluminum alloy) with an approximately square external cross section (eg 80 mm × 90 mm). The cross section of this extruded profile consists of fourteen individual, partially completely and partly only largely self-contained "cells". These cells are passed through a series of different chambers 13 passing through the entire axial length of the extruded profile. 13z; 14 a, b; 20 a, b, c; 19b; 21, 22 formed. This "cell-like" or chambered construction makes the door sill 5 extremely torsion or bending stiff - although it is designed as a thin-walled extruded profile. The threshold can therefore be mounted cantilever without a so-called subthreshold, ie without relining with a rigid metal profile, which supports the threshold over the whole or almost the entire length against the person or wheel loads acting on it. This will be discussed later.

Looking at the Fig. 3 It is the first thing to notice that the door sill has six parallel stiffening chambers 13 and 13 z seen in the longitudinal direction, with possibly only five stiffening chambers 13 to 13 z being provided, even if this does not guarantee quite so much stability and is therefore not preferred is, cf. Fig. 6 , Each of these stiffening chambers 13, 13 z is from all other chambers on all sides by in Longitudinal walls delimited. These delimiting walls are free of slits or the like that pass completely or partially through in the longitudinal direction, so that in fact an all-round delimitation is given. Of course, these walls may have localized breakthroughs as long as and as far as they do not reduce the rigidity in a functionally relevant manner. Preferably, however, the walls of these chambers are really executed without any breakthrough or without any opening. Optimally, one of these stiffening chambers - such as here the chamber 13 z - centrally arranged and forms, as it were, the rigid backbone of the profile around which the various functions realizing chambers are arranged.

In addition to the stiffening chambers 13, 13 z, the door threshold has two further, longitudinally continuous guide chambers 14 a and 14 b, of which each has at least a portion of a boundary wall with one of the gain chambers 13 and 13 z in common and thus directly from a particular rigid area is supported. Each of the guide chambers 14 a and 14 b has on one side a through opening to the outside. (As far as the threshold is made differently than by continuous extrusion, the intended above, to be arranged on the floor or car floor towards leadership chamber may be only partially provided with an opening to the outside, namely only in their later used by the guide shoes area.) This Guide chambers 14 a and 14 b are provided with guide surfaces 15, whereby these guide chambers provide the already mentioned guide grooves 6 and 7 for the guide shoes. These guide surfaces are designed here as cantilevered and pointed towards its free end cantilevers. As cantilevers, the free end of each project into the below the guide sections, expanding chamber portion 16 protrude. The guide surfaces 15 can be so easily and with high accuracy produced in the context of extrusion.

The guide chambers 14 a and 14 b are designed so that the guiding surfaces guided along the guide surfaces 15 a considerable play up and down is made possible. This refinement also makes it possible for foreign bodies, which have reached the area of the guide surfaces 15, to fall downwards and to be deposited in the widened region 16 a or 16 b of the guide chamber 14 a or 14 b. They do it in one such distance from the guide surfaces 15 that the guide shoes are usually not disturbed.

The guide chamber 14 b, which serves to receive the guide shoe of the fast-moving door leaf, is preceded by an antechamber 19. This pre-chamber 19 ensures that the guide chamber 14 b is accessible only from the shaft side and from the surface of the floor or car floor 18 ago no foreign body can get into the guide chamber. The opposite of the floor or car floor side delimiting wall of the antechamber 19 is made reinforced or, as here, at least at its clamping point massively connected (see, the generous radius at the root of this wall). This ensures that this unilaterally projecting wall does not unduly deform under passenger or wheel loads.

It should also be noted that at least one, preferably both guide chambers in the (outside) area, which is not traveled by the guide shoes in normal operation, can have a window-like cutout, which allows threading the respective guide shoe in the guide chamber to thread out of her, especially for the purpose of simplified maintenance, cf. also Fig. 3 , The reference A indicates in Fig. 3 in a dashed line, which illustrates how the appropriate place to be provided window can be realized. Namely, by the wall portion above the line A is not locally present, because z. B. weggefräst. Where no such window-like cutouts are provided, the guide shoes must be successively inserted and unfolded from the exposed end face.

In addition, the shows Fig. 3 in that the door threshold according to the invention is provided with a plurality of T-slot chambers 20 a, 20 b, 20 c which are designed to be continuous throughout and extend parallel to the previously described chambers 13, 13 z and 14 a, b. These T-slot chambers 20 a, 20 b, 20 c are designed so that they can give a bolt head, a nut or a threaded nut a positive fit. In this way, the threshold according to the invention can be screwed in place. At least one of the T-slot chambers 20 a, 20 b, 20 c is (based on the intended mounting position) at the bottom of the invention Threshold provided here z. B. the T-slot chamber 20 a. By means of this T-slot chamber 20 a, the door threshold of the invention, if it is used as a door sill for a shaft door system, without using a sub-threshold of L-shaped fixed to the building consoles are set. The T-slot chambers 20 b and 20 c are, based on the intended installation position of the door sill 5, provided on the side of the door sill 5. These T-slot chambers 20 b and 20 c make it possible to screw the door threshold when used for a car door to a corresponding perforated plate of the elevator car or the car, as it is on the right side of Fig. 2 can be seen (without reference number). The differently positioned T-slot chambers 20 a, 20 b, 20 c thus make the door threshold according to the invention universally applicable.

Of course, can be used in an equivalent to the T-slot chambers 20 a, 20 b, 20 c also slightly different profiled chambers, such as chambers, can be spread or latched into the holding members, or the like. Nevertheless, a T-slot-shaped design is preferred.

Finally, the shows Fig. 3 in conjunction with a detailed detail representing Fig. 4 as further, seen in the longitudinal direction through apron mounting chamber 21 and provided in the same way, also in the longitudinal direction through screw-22. These two chambers are used to attach the door apron 23, which is also part of the elevator door system. This door skirt 23 indicates what is particular in Fig. 4 but also in Fig. 2 can be seen on several notches, ie oblique, flag-like extensions. With these extensions, the door apron 23 can be hung in the apron mounting chamber 21 and then conveniently positioned accurately by pushing back and forth in the horizontal direction. The door skirt 23 is provided just above these notches with holes / punched. Through these holes each a sheet metal screw is inserted and screwed into the screw 22 for final fixation of the door apron. The sheet metal screw cuts in the top and bottom of the walls of the Einschraubkammer 22 a. Different, than from Fig. 4 As shown, the tapping screw will normally be a countersunk screw whose countersunk head terminates flush with the surface of the door apron 23 when fully screwed in. The door threshold according to the invention has a return in the region of the chambers 21 and 22, as in close up in Fig. 4 shown. In the way the door apron 23 can be mounted flush with the door sill after final adjustment, which reduces the required space and the risk of accidents. Because there are no dangerous steps or protrusions.

Comparing the Figures 3 and 4 then one recognizes further details to Einschraubkammer 22. The screw-22 is, as I said, designed as a longitudinally completely continuous groove / chamber. In this way, the screw can be screwed in any position. The groove is divided into three sections. Namely, a first outwardly directed portion that allows the tip of the tapping screw to be inserted without the tapping screw having to penetrate into the material. This is followed by a narrowed section. In this section, the thread of the tapping screw cuts. Finally, inside a re-expanded section is arranged, which serves as an outlet for the screw thread or z. T. also serves as a compensation space for the screw when cutting the thread plastically displaced material of the door sill. Belonging to the door system and serving to fasten the door apron tapping screws and the screw 22 of the door sill 5 are alternately dimensioned so that the tapping screws clean in the screw clean a thread without aufzpreizen the screw-in and thus deform the door sill inadmissible.

It should also be noted that the stiffening chamber 15 forming the backbone is designed and dimensioned so that it can absorb resistance heating where weathered door thresholds have to be executed, and its supply line can be led outwards via a corresponding, local opening. Here, the stiffening chamber 15 benefits its central location. It adjoins both directly to the guide chamber 14 a and the guide chamber 14 b and can therefore very effectively prevent that in the guide chambers 14 a and 14 b penetrated rain, dew or condensation freezes.

In connection with the Fig. 3 It is worth noting that over the entire threshold profile, the wall thicknesses are almost the same almost everywhere. Deviating wall thicknesses are provided only in special, few areas where the function requires a thicker wall thickness. This is z. As the area of the side edges of the lower T-slot chamber 20a, the area of connection of the upper wall of the pre-chamber 19 and there are the portions of the apron mounting chamber 21 and the Einschraubkammer 22nd

It has already been mentioned that the threshold according to the invention can be mounted without a so-called lower threshold due to the rigidity achieved by its chambering, d. H. without relining with a rigid metal profile that supports the door sill over its entire or nearly full length. This will be discussed later.

This illustrates the Fig. 5 , Shown here is a landing position in front of the floor located car. The car and the landing doors are aligned. The invention, the gate door system associated door threshold is here without sub-threshold on brackets 17, the z. B. consist of narrow flat iron, stored and held - without the risk of undue deflection of the threshold occurs when entering or driving. Here, the door sill 5 is screwed here by means of continuous countersunk bolt together with the cover plate 12 to the brackets 17.

It is worth noting that just the Fig. 5 makes clear what advantages arise when for the connection between the actual guide shoes F and the door panels due to the inventive type of leadership thin (preferably 4 to 10 mm thick), quite wide sheets can be used instead complicated cranked and thus because the long lever arm tubular structure - the free gap between the elevator car and the car and the shaft wall can be kept extremely small.

The Fig. 7 shows a special fastening system to facilitate the installation and adjustment of the bracket for the guide shoes (and possibly other attachment parts), which are needed at the bottom of the door panels. How on hand Fig. 7 can be seen, the door panels (here door panel 4) in the region of its lower end with a mounting profile (here 4a) equipped with a plurality of slots, which is used for fastening of the Holding clip (here 4b) has at least one guide shoe in the different, required in the specific case individual positions. The mounting system also offers subsequent modification options - z. B. during commissioning, that the door panel tends to tilt in its plane of motion or jerk, the guide shoes can be thanks to the mounting profile without much effort u. U. later retrofit to further apart from each other places to turn off the problems.

The mounting profile is a bent sheet metal part. It has a U-shaped section 40 (equivalent: C-profile-shaped section), wherein in Fig. 7 one of the two side legs of this section carries said plurality of holes. Without prejudice to the fact that the Fig. 7 shows only 5 holes and indicates two more by center lines, holes are provided as a rule almost across the entire width of the door panel away, but preferably more than a total of eight holes per Türpaneel. In any case, more holes are provided per door panel than the otherwise provided for attachment per headband in a single position holes x number of headband.

The middle part of this U-shaped section is flat on the door panel and is with this z. B. by spot welding - wherein the welding parameters and the heat-dissipating mass of the cooled, on the side view scheduled welding counter-holder are chosen so that the typical circular penetration 43 is kept as small as possible on the visible side of the door panel, such that it is painted door with 1.20 m distance is essentially no longer visible.

At this side legs of the U-shaped profile section includes another L-shaped profile portion 41 with a common perforated leg. This is such that the hole-carrying area is double-layered and therefore has a much higher bending stability. This anyway, as soon as the two individual layers after tightening the (not shown here) through bolts of a flanged retaining bracket have been frictionally braced against each other and therefore behave like a single, "thick cantilever".

The U-shaped and the L-shaped section 40 and 41 are part of a one-piece bent sheet metal part. This is carried out in such a way that the L-profile-shaped section in the Fig. 7 shown embodiment by twice folding (180 degrees, 90 degrees) of the previously long leg of the U-shaped section has arisen. It is important that the L-shaped section additionally supports the hole-carrying area. This in that the legs facing away from the hole-carrying region of the L-profile-shaped portion is also dotted on the door panel - in the manner previously described for the U-shaped profile section.

At the other side legs of the U-shaped profile section is followed by a further bend 44, which at the of Fig. 7 shown construction is folded by about 90 degrees and thus provides a lateral stop for a supported by the top of the mounting profile guide rail for guiding on another or another door panel. In this way, the guide rail is always aligned exactly parallel on the holding door panel, without the need for cumbersome adjustment. Accordingly, simply the associated (in Fig. 1 to be recognized) screwed: The guide rail is held here by bolts on the mounting profile, the appropriately selected heads engage in the manner of sliding blocks in the downwardly open U-profile section of the guide rail and by means of corresponding nuts to the (in Fig. 1 to be recognized) upper leg of the mounting profile are tightened. In this way, the position that occupies the guide rail in the direction of movement of the door panels, very easy to adjust.

Evidently the Fig. 1 the lateral edge of the slow door panel is provided in the region of the mounting profile with a recess 45 to allow the mounting profile to pass the edge of the door panel and so to create a mounting base for the mounted behind the door panel headband 4b (mounting profile in Fig. 7 drawn off, cf. Hatching).

The Fig. 8 a to d and 9 a to d show the belonging to this special fastening system headband 3b and 4b. The retaining clips (3b, 4b) shown by the above-mentioned figures are here produced as thin-walled (approximately 3 to 5 mm thick) bent sheet metal parts. they consist of a horizontal portion 46 for connection to the respective mounting profile (3a, 4a) and the actual guide shoe L holding, optionally cranked vertical portion 47. The horizontal and the vertical portion are connected via generous Langlochverschraubungen 48 and therefore adjustable relative to each other. After the horizontal portion 46 in turn is adjustable on the mounting profile and can be set in various positions on the mounting profile, there is a maximum freedom in the attachment and adjustment of the headband. In addition, this design of the system makes it possible to use a very simple design, essentially single-walled and bent only on the outer edges sheet metal profile as a door panel.

It is also noteworthy that the oblong holes provided for connecting the horizontal section 46 and the vertical section 47 are designed as slots for countersunk screws 49. In this way, the gap between the car and the shaft surround can be minimized.
