Description

The invention relates to a frame construction for a sliding door with a metal frame, which is screwed together from two lateral frame profiles, a downwardly open, lower frame profile and an upwardly open, upper frame profile, wherein the lower and upper frame profiles are each formed by a U-profile , which has a center leg, two side legs and a longitudinally extending on the center leg longitudinal channel, which is open at both ends of the U-profile for screwing in frame connection screws, and with straightening elements which align the frame profiles in the region of their joints to each other.

Such a frame construction for a sliding door is for example by the DE 10 2007 059 222 A1 known.

In this known frame construction, the individual frame profiles are centered on straightening elements in the form of one or more stabilization plates made of wood, which engages in a circumferential inner groove of the frame profiles.

The invention is based on the object to provide alternative directional elements in a frame structure of the type mentioned.

This object is achieved in that the two side frame profiles are each formed by a rectangular tube with molded C or U-profile and bear the front sides of the lower and the upper frame profile on the open profile side of the C or U-profile and that the Straightening elements are designed as metal angle, which engage with a leg play in the tube opening of the rectangular tube and are screwed on the inside of the rectangular tube and engage with another leg, the lower or upper frame profile either backlash or engage it clearance.

According to the invention a metal angle is used as a directional element, which is bolted to the side frame profile and aligns by its outer contours, the lower and upper frame profile to the side frame profile.

In a particularly preferred embodiment of the invention, the metal angle is formed as a U-angle, which rests with its engaging in the pipe opening of the rectangular tube, the first side legs inside a pipe wall of the rectangular tube and is screwed thereto and with its second side legs outside of the open profile side of the C or U profile is present.

In an advantageous development of this embodiment, the first side limb of the U-angle engages in a longitudinal groove of the tube wall and the second side limb between the two side limbs of the U-profile of the lower or upper frame profile in each case without play, whereby the frame profiles are mutually aligned are aligned exactly. Preferably, the first side leg of the U-angle is screwed by means of the frame connecting screw to the rectangular tube.

In a further advantageous embodiment of this embodiment are on the underside of the frame rollers down, which are rotatably mounted in two roller carriers, which are each attached to a U-angle, about a horizontal axis of rotation. The U-angle thus serves not only to align the frame profiles, but also for attachment of the roller carrier to the metal frame. The roller carrier can be attached to the U-angle by means of a screw which passes through both side legs and is screwed into the Laufroflenträger. Thus, the roller carrier including roller can be adjusted by turning the screw in height.

In a further particularly preferred embodiment of the invention, the metal angle is formed as a rectangular angle, which rests with its engaging in the pipe opening of the rectangular tube, first angle leg inside a pipe wall of the rectangular tube and is screwed thereto and with its second angle leg on top of the upwardly open U-profile of the upper frame profile rests.

In an advantageous embodiment of this embodiment, the first angle leg of the rectangular angle engages in a longitudinal groove of the pipe wall without play, while the second angle leg with two downwardly angled side edge portions, the two side legs of the U-profile surrounds backlash. Preferably, the second angle leg of the rectangular angle is screwed to a mounting plate, which is arranged in two inner longitudinal grooves of the side legs of the U-profile, in particular clipped.

In a further advantageous development of this embodiment, guide rollers project laterally on the frame top, which are rotatably mounted on the second angle leg about a vertical axis of rotation. The rectangular angle thus not only serves to align the frame profiles, but also serves to support the guide rollers or for mounting a guide roller carrier on the metal frame.

Preferably, a provided on the frame top pull-in damper - or other components - screwed to at least one mounting plate with thread passage (sliding block), which is arranged in two inside longitudinal grooves of the side legs of the U-profile of the upper frame profile, in particular clipped. The positioning in the direction of the width of the door is performed by means of screws. Here, the attachment clamps by the backlash of the screw to the mounting plate to the upper frame profile.

Advantageously, the lower and the upper frame profile is formed in each case by a U-shaped profile with molded C or U-profile, wherein the molded C or U profiles of all frame profiles can form a circumferential inside the metal frame groove.

Particularly preferably, both the two side frame profiles are identical in construction as well as the lower and the upper frame profile of identical design. The individual frame profiles can then be cut to the desired profile length.

On at least one of the two side frame profiles, a penetration protection may be attached, which is particularly advantageously composed of several profile pieces of the same profile as the lateral frame profiles. When assembling the door, the penetration protection is located just behind a handle cutout of the planking panels and can be fixed by means of adhesive tapes to the planking panels of the sliding door.

The invention also relates to a sliding door with a frame construction constructed as above and with one or two planking panels, in particular glass panels, which are glued on the outside to profile side walls of the frame profiles by means of adhesive tapes.

Further advantages of the invention will become apparent from the description, the claims and the drawings. Likewise, the features mentioned above and the features listed further can be used individually or in combination in any combination. The embodiment shown and described is not to be understood as a final enumeration, but rather has exemplary character for the description of the invention.

The planking is designed depending on the application on one or both sides.

As in Fig. 1 shown, stand on the underside of the frame two lower rollers 9 , which in two roller carriers 10 (FIG. Fig. 4 ), which are fixed at a distance from each other on the underside of the frame, are rotatably mounted about a horizontal axis of rotation. Upper guide rollers 11 are provided on the frame upper side, which are offset in pairs and in the direction of the frame thickness relative to one another in two guide roller carriers 12 (FIG. Fig. 5a ), which are fixed at a distance from each other on the frame top, rotatably mounted about a vertical axis of rotation.

The two side frame profiles 3, 4 are identical extruded aluminum and, as in FIGS. 2a, 2b shown, each formed by a combination of a rectangular tube 13 with a rectangular tube opening 14 and a C-profile 15 . The (inner) profile wall, which simultaneously forms a tube wall of the rectangular tube 13 and the center leg of the C-profile 15 is denoted by 16 and the opposite (outer) tube wall of the rectangular tube 13 with 17 . In each of these two tube walls 16, 17, an inner longitudinal groove 18 extends, and in the two other tube walls in each case an inner longitudinal groove 19 extends. The side walls of the rectangular tube 13 and the C-profile 15 together form the two profile side walls 20th The open profile side 21 of the C-profile 15 extends parallel to the tube walls 16, 18. To stiffen the rectangular tube 13, can be in the tube opening 14, more precisely, in the two longitudinal grooves 19, a square tube made of steel (not shown) introduce ,

The lower and the upper frame profile 5, 6 are identical extruded aluminum and, as in Fig. 3a, 3b shown, each formed by a combination of a U-section 22 and a C-profile 23 . The profile wall, which simultaneously forms the center leg of the U-profile 22 and the center leg of the C-profile 23 is denoted by 24 . The two side legs 25 of the U-profile 22 together with the two side legs of the C-profile 23, the profile side walls 26th The U-profile 22 has on the inside of the center leg 24 a longitudinal channel 27 , which is open at both ends of the U-section 22 for screwing the frame connecting screws 7.

In bolted metal frame 2 are the lower and the upper frame section 5, 6 with their end faces on the open profile side 21 of the C-profile 15 of the side frame sections 3, 4, wherein the C-profiles 15, 23 of all four frame profiles 3-6 together can form a circumferential in the metal frame 2 inner groove. The frame connecting screws 7 are inserted through a larger access opening 28 in the outer tube wall 17 and a smaller opening 29 in the inner tube wall 16 of the side frame profile 3, 4 and screwed into the longitudinal channel 27 of the lower and upper frame profile 5, 6, until they each with their screw head inside the inner tube wall 16 abut. The profile side walls 20, 26 of all frame profiles 3-6 together form the two flat frame sides of the metal frame 2, to which the glass plates 8 are glued. The frame profiles 3-6 are in the region of their joints not already aligned by the frame connecting screws 7 exactly to each other, since the frame connecting screws 7, the smaller openings 29 always prevail with play.

For the exact alignment of the frame profiles 3-6 serve metal angle in the form of U-angles 30 ( Fig. 4 ) for the lower joints and rectangular angles 31 ( Fig. 5a ) for the upper joints.

As in FIGS. 4a, 4b shown, the U-angle 30 with its one (longer) side legs 30a inserted into the tube opening 14 of the rectangular tube 13 and with its other (shorter) side legs 30b in the downwardly open U-section 22 of the lower frame profile 5 each without play, to the U-angle 30 abuts with its center leg 30c on the lower end side of the lateral frame profile 3. More precisely, the longer side leg 30a is inserted backlash-free into the central longitudinal groove 18 of the inner tube wall 16 and the shorter side leg 30b without clearance between the two side legs 25 of the U-profile 22, whereby the lower frame profile 5 and the lateral frame profiles 3, 4 are aligned centered are. The longer side leg 30a bears against the tube wall 16 on the inside and the shorter side leg 30b on the outside on the open profile side 21 of the C profile 15. About the frame connecting screw 7, which passes through an opening 32 in the longer side leg 30a, the longer side leg 30a is screwed to the inner tube wall 16. Of the Screw head of the frame connecting screw 7 is accessible through the access opening 28 of the outer tube wall 17.

As in FIGS. 4a and 4b further shown, the roller carrier 10 is screwed to the U-bracket 30 by means of a screw 33 . This screw 33 passes through an opening 34 in the inner tube wall 16 and is screwed into the roller carrier 10 until its head on the outside of the longer side leg 30 a rests. The screw head of the screw 33 is accessible through an access opening 35 of the outer tube wall 17. The roller carrier 10 together with roller 9 can be adjusted in height by turning the screw 33. The U-angle 30 thus serves not only to align the frame profiles 3, 4 and 5, but also for attachment of the roller carrier 10 on the metal frame. 2

As in Fig. 5a shown, the rectangular angle 31 is inserted with its one, shorter angle leg 31a in the tube opening 14 of the rectangular tube 13 without play until it rests with its other, plate-shaped angle leg 31b on top of the upwardly open U-section 22 of the upper frame profile 6 and two down angled, lateral edge portions 36, the two side legs 25 of the U-section 22 surrounds backlash. More precisely, the shorter angle leg 31a is inserted free of play into the central longitudinal groove 18 of the inner tube wall 16, whereby the upper frame section 6 and the lateral frame profiles 3, 4 are aligned centered. Via a screw (not shown), which passes through the upper openings 34 in the inner tube wall 16 and is screwed into a threaded bore 37 of the shorter angle leg 31 a, the shorter angle leg 31 a is screwed to the inner tube wall 16. The plate-shaped angle leg 31 b is attached to the U-profile 22 by means of a screw 38 which is screwed into a threaded bore 39 of a mounting plate 40 . As in Fig. 5b shown, this mounting plate 40 is clipped into two longitudinal grooves 41 of the lateral side legs 25 of the U-profile 22, wherein the clipping is facilitated by two chamfers 42 on the side walls 25.

As in FIGS. 5a further shown, the guide roller carrier 12 is formed by the plate-shaped angle leg 31 b, at which the two guide rollers 11 to the vertical axis of rotation are rotatably mounted. Furthermore, a pull-in damper 43 is fixed by means of two screws 38 to two mounting plates 40 on the frame top, which are clipped into the inside longitudinal grooves 41 of the side legs 25 of the U-section 22. By longitudinal displacement of the mounting plates 40 in the longitudinal grooves 41, the position of the Einzugsdämpfers 43 can also be adjusted later.

As in FIGS. 6a-6c is shown in the C-profile 15 of the side frame profile 3, 4, a U-shaped penetration protection 44 is inserted, which is composed of several (here three) profile pieces 45a-45c of the same profile as the side frame sections 3, 4. The profile parts 45a-45c are mitred and connected by means of miter connectors 46 , which are also clamped in the C-profile 15 at the same time, namely are clamped by their groove contour on the legs in the C-profile of the side frame profile. One or as here two Griffinlayplatten 47 are inserted into the circumferential inner groove of the profile parts 45a-45c, in the previously a protective profile 48 has been inserted. The two Griffinlayplatten 47 may correspond to the Plankungsplatten 8 in color and material.

The two glass plates 8 are glued by means of double-sided adhesive tapes (not shown) to the profile side walls 20, 26 of the four frame profiles 3-6, which each have two orientation lines 49 for adhering the adhesive tapes. The profile parts 45a-45c are provided with double-sided adhesive tapes and thereby fixed to the glass plates 8. When assembling the sliding door 1, the penetration protection 44 is located just behind a handle cut 50 of the glass plate 8. The glued glass plate 8 is located, as in FIGS. 4a and 4b shown at the bottom of a profile paragraph 51 of the lower frame profile 5 and is, as in Fig. 5a indicated, protected by a profile paragraph 51 of the upper frame profile 6 in front of the downwardly angled edge portions 36 of the rectangular angle 31.

As in FIGS. 4a, 4b 1, the roller carrier 10 has a spring 52 embodied here as a leaf spring, which springs on inside profile projections 53 (FIG. Fig. 3b ) of the two side legs 25 of the lower frame profile 5 is supported and the roller carrier 10 in a downwardly over the lower frame profile 5 maximum projecting Biased position. By turning the screw 33 of the roller carrier 10 can be adjusted in height, either further against the action of the spring 52 in the U-section 22 of the lower frame profile 5 or by the action of the spring 52 further out of the U-profile 22 , By a stop element (mounting aid) 54 which is longitudinally displaceably guided in the two longitudinal grooves 41 of the U-profile 22, the roller carrier 10 is blocked against slipping out of the lower frame section 5 when hanging the sliding door 1 by the prestressed roller carrier 10 with two paragraphs 55 abuts against the stop element 54. After the sliding door 1 is mounted, the stopper member 54 is pushed back manually, thereby canceling the blockage of the roller carrier 10.

In conjunction with translucent panel materials, such as ESG or laminated safety glass with a corresponding foil on the back side, the frame construction largely disappears for a viewer standing in front of the sliding door 1. Only from the narrow side of the side frame profile 3, 4 is still visible.
