Description

The invention relates to a front door, in particular insect screen, comprising a sliding wing, two roller bearings and provided below the sliding leaf track, wherein the sliding wing consists of four composite into a rectangular shape frame profiles, and wherein the sliding leaf is slidably mounted on the slide rail on the two roller bearings.

Such, z. B. off US 5,119,872 A Known intentional doors, usually in the form of insect screens, are usually mounted in the balcony or terrace area. They usually consist of a fixed position, usually encircling frame, which consists of four to Rahmenförmckform assembled, metal profile bars, usually aluminum profiles. In this a sliding wing is included, also comprising a sash, which is composed of four metal profile bars, usually also aluminum profiles, in which sash a grid or fabric is held by a piping. About a roller bearing of the slider wing is on the bottom side on a running rail, which is provided on the positionally fixed outer frame, horizontally displaceable on the positionally fixed frame respectively the running rail added. It may, for example, also be guided over rollers on the upper side or via a simple, pivoting out of the sliding leaf avoiding storage and the like. The user can open the front door by simply pushing the side of the sliding sash. The sliding sash is then pushed back by the user to close it.

Occasionally, however, unevenness is given on the bottom side, with the result that the relative position of the sliding leaf, which, as described, is usually also guided via roller bearings or plain bearings via which it is suspended from a corresponding guide rail of the frame, depending on the situation, Consequently, therefore, the distance between the running rail and sliding sash varies depending on the installation situation.

The invention is therefore based on the problem of specifying a front door, which allows an exact adaptation of the sliding leaf storage to the structural conditions.

To solve this problem is provided according to the invention in a front door of the type mentioned that one or both roller bearings consists of a roller holder, a rotatably mounted on this role, and a locking / consist, wherein the roller holder in a chamber of a vertically arranged frame profile of the sash over the locking element is infinitely adjustable in height received, that the running rail engages behind the lower frame edge of the sliding leaf, and that the role in the mounting position - seen horizontally - is hidden behind the frame edge of the sliding sash.

In the front door according to the invention a stepless height adjustment of the roller, so the roller bearing, realized so that an exact, millimeter accurate adjustment respectively adjustment of the height of the roller is possible. For this purpose, there is a respectively consist both roller bearings each having an elongated roller holder and a roller arranged on it. The roll holder is slidably received in a hollow chamber of a vertically arranged frame profile of the sliding leaf. This chamber extends, after it is usually an extruded profile in such a frame profile, over the entire profile length. The role holder can thus be inserted as far as desired in this chamber and fixed in any position via a locking element. This inevitably results in any height positioning of the role.

The role itself is always taken so far in the mounting position in the "inside" of the sash that it, horizontally, is not visible. It is hidden behind the lower sash rim. The running rail engages behind this frame edge, so that a hidden inside the frame positioning of the role is possible. This results in a visually appealing and in particular also protected from contamination, etc. arrangement of the Roller bearing with exact adjustability with respect to the actual position of the track, which varies depending on the installation situation and given bumps etc. extends far into the frame interior, so far different reaches the frame edge.

A particularly advantageous development of the invention provides that the diameter of the roll is smaller than the width of the chamber in which the roll holder is received, or that the width of the roll is dimensioned such that the roll holder together with roll can be inserted into the chamber. If the running rail engages very far from below into the frame or behind the edge of the frame, it is possible to move the roller bearing so far vertically that the roll is largely received in the chamber. This means that the roller bearing can also be adjusted according to the smallest distances of the running rail for sliding sash frame.

The chamber in which the roll holder is received is preferably laterally open and limited by two stop shoulders, wherein the roll holder is pressed against the abutment shoulders via the locking element mounted on the opposite chamber wall. On the side opening of the chamber can be easily accessed on the reel holder, on the one hand to actuate the locking element, which is preferably designed as a screw which is screwed into a hole provided on the roll holder. Particularly preferred for this purpose a grub screw is used. This is screwed until it is supported on the opposite chamber wall and presses the role holder to the opposite, the chamber undercut stop shoulders with a corresponding further screws. On the other hand, it can be attacked via the lateral chamber opening on the roll holder for vertical displacement of the same for the purpose of adjustment. For this purpose, a handling section projecting from the chamber side can be provided on the roll holder, which can be attacked, in particular if the frame has two wall sections extending further to the side, and thus thus the chamber deeper inside Frame profile is located. The laterally projecting handling sections can be easily grasped even with such a profile training.

As described, the locking element is preferably designed as a screw, in particular as a grub screw, which is screwed into a bore on the roller holder, which is provided in particular with an internal thread. It would also be conceivable to use, instead of a screw, the use of a relatively strong spring, which protrudes on one side of the roller holder and is supported on the inner chamber wall. The spring presses the reel holder back against the two stop shoulders. To move the roller holder must be pressed firmly against the spring, so that it is released from its clamp and can be moved vertically. The spring may have, for example, a shoe or the like for this purpose.

As described, in the assembly position, the roller is the component of the roller bearing projecting furthest downwards in the "interior" of the sliding leaf frame, ie it is arranged hidden. In order to achieve an even more "encapsulation" to avoid contamination, the sliding panel respectively the horizontal lower frame section is expediently provided with a downwardly open chamber into which the running rail engages. This means that there are virtually two vertical walls between which the running rail engages. For reasons of economy, it is particularly useful if all four frame profiles that make up the sash are identical. That is, each frame profile has an inner chamber, wherein in the chambers of the vertical frame profiles, the roll holder are accommodated. This is adjoined to the side, the further, laterally open chamber, on the one hand, the handling portion of the roll holder can be gripped, and in the other to the running rail engages.

In order to improve the seal even further to prevent the ingress of dirt or insects, a brush sealing the running rail is expediently also arranged on the sliding leaf, in particular on the inside of the rearwardly engaged frame edge or the open chamber. These Brush, which is aligned horizontally with its bristles, lies in the mounting position on the side of the running rail, seals in this area so against the ingress of dirt, but of course also from insects and the like from.

Fig. 1 shows a front door according to the invention 1 comprising a sliding leaf 2, which is horizontally slidably received in an outer frame, not shown in detail. The outer frame comprises an upper, horizontal lying frame profile, on or in which the sliding leaf 2 is suspended via a not-shown roller or plain bearings. The slider wing "hangs" so to speak on the top of this frame profile. On the underside, the outer position-fixed frame has at least one running rail, for example, in the Figures 5 and 7 is shown. On this, the sliding leaf is guided horizontally movable on lower roller bearings, which will be discussed below. This means that the sliding sash is movably guided both at the top and at the bottom according to horizontal guides (upper frame profile, lower running rail).

The sliding wing 2 consists of a sash 3 consisting of a total of four connected to a Rahmenrechteckform frame profiles 4, all of which are identical in construction. These are extruded aluminum profiles. A fabric 6 is fixed in the casement 3 by means of a welt 5, that is to say that the front door 1 is an insect screen. Since the internal structure of the frame profiles 4 forming the sash frame 3 is important for the understanding of the invention, this will be described with reference to FIG Fig. 4 explained in more detail. In Fig. 4 is the mitred end of the also in Fig. 1 shown lower horizontal frame profile 4 shown. This consists in addition to an inner profile section with a groove 7 in which the piping 5 is added. At this profile section, a section closes with a first inner and closed chamber 8, in which usually a Verpresswinkel is used, ie an angled 90 ° element over which two in the corner abutting, cut miter frame profiles 4 are connected. To this closed chamber 8 is further outside a laterally open chamber 9 connects, which has an inner chamber wall 10, and two outer stop shoulders 11, over which it is undercut. This chamber 9, which is provided in all four frame sections 4, serves to receive a roller bearing 12, as shown in the figures, which will be discussed below, however.

To the chamber 9 further close to the outside two wall sections 13, which is also open at the side, so that a total of the chamber 9 is accessible from the outside.

Fig. 1 shows the inserted into the chamber 9 roller bearing 12, which there by means of two locking elements 14 in the form of two grub screws 15, which are screwed into corresponding holes, preferably internally threaded holes 15 which are formed on a roller holder 16, is fixed. The grub screws 14 press against the chamber wall 10, so that the roller holder 16 is pressed against the two stop shoulders 11.

On the roll holder 16 is, see Fig. 3 , A roller 17 is arranged, which is rotatably mounted there. The roller 17 runs in the mounting position on the upper edge 18 of a running rail 19, as exemplified in Fig. 5 is shown.

The roll holder 16 is, see Fig. 3 , in its shape substantially rectangular, it thus corresponds approximately to the shape of the chamber 9. It is dimensioned such that it can be easily moved vertically in the chamber 9. For this to be possible and to be used, two wings 21 are formed on the roll holder 16 as a handling section 20, which engage between the stop shoulders 11 in the region between the wall sections 13 and can be grasped from outside by the operator. By way of this, the roller holder 16, ie the entire roller bearing 12, can be moved vertically in order to be able to adjust the height of the roller 17.

The roll 17 itself has a small width, it is dimensioned in its width so that it fits between the stop shoulders 11, and thus can be pushed through it. This makes it possible to push the roller holder 16 together with roller 17 as far as desired into the chamber 9, without the roller 17 abutting anywhere. This is further made possible by the fact that the pivot bearing of the roller 17 about the axis 22, with respect to the longitudinal center of the roller holder 16, slightly eccentric, but this is not mandatory.

As part of the assembly of the sash 2, before two mitred frame sections 4 are firmly connected, the roller bearing 12 is inserted with its role holder 16 in the chamber 9 of the vertically arranged frame profile 4, after which the two Frame profiles 4 are connected via suitable connecting means (Verpresswinkel).

If now the front door to be mounted, so after first the positionally fixed frame or the guide rails, whatever the attachment door is constructed concretely mounted, the sliding wing fixed on the top side, so hung on an upper-side frame profile and the like. Then, the two lower roller bearings 12 (the sliding leaf of course has a roller bearing on each vertical frame profile 4, ie on both vertical sides, on) so far moved down until they on the running rail 19 respectively whose upper edge 18, between the side walls 13th and optionally engages into the chamber 9 of the lower frame profile 4, sit up. Then, the roller holder 16 is fixed on the grub screws 14, so screwed tight, so that the adjusted storage position is maintained.

So it is a continuous positioning of the roller bearing 12 on the vertical frame profile 4 possible. In addition, the roller bearing 12 is located entirely in the interior of the sash frame 3, after, see Figures 5 and 7 , the running rail 19 always engages behind the lower edge portion of the lower horizontal frame profile 4 respectively engages in this. In addition, the design of the roller size or their width allows any height adjustment of the roller bearing 12 with respect to the actual position of the upper edge of the rail 18.

Fig. 4 shows a first positioning of the roller bearing 12, wherein of course the located on the opposite side frame roller bearing 12 is also positioned in this position. As can be seen, the roller bearing 12 is pushed very far, the roller 17 protrudes only a very short distance beyond the wall 10 of the chamber 9 of the horizontal frame profile 4 addition. The running rail 19 thus extends very far into the sliding sash frame 3, as in Fig. 5 is shown. Nevertheless, an exact adjustment of the position of the roller bearing 12 can take place.

Out Fig. 5 It can also be seen that on the horizontal frame profile 4 on the inside of the inner wall 13, a brush 23 is received in an undercut groove 24. This brush 23 (usually an elongated brush strip) abuts against the running rail 19 and seals to this. Since the brush 23 is attached to the sliding sash 2, it is moved with this, so it travels along the track rail 19th

Fig. 6 shows a second adjustment position of the roller bearing 12. Here, the running rail 19 engages only a short distance between the wall portions 13 of the lower horizontal frame profile 4. The roller bearing 12 is significantly further lowered compared with the arrangement according to the FIGS. 4 and 5 , nevertheless sits exactly adjusted on the upper edge 18 of the track rail 19. The brush 23 in turn seals to the running rail 19 out.

It is evident, however, that the roller 17 or the entire roller bearing 12 is always completely "hidden" in the interior of the sliding sash frame 3, even in this very largely lowered positioning of the roller bearing 12, so it is not visible from the outside.

Overall, the inventively provided structure of the roller bearing with the narrow roller holder 16 and the relatively narrow in its width particularly dimensioned roller 17, that the roller bearing 12 as far as possible, so over the range of Gehrungsstoßes two in the corner abutting frame profiles out to push vertically upwards because neither the roller holder 16 nor the roller 17 abuts anywhere, especially since the roller 17 can engage between the stop shoulders 11 due to their small width and their optionally eccentric pivot bearing relative to the longitudinal center of the roller holder 16.
