Hardware for sliding doors and windows

Sliding doors and sliding windows usually have two parts, one fixed part and a part that can be moved relative to it. This sliding part or sliding sash is made by means of rollers on a profile rail between the open position and the Moved closed position back and forth. To close the closing leaf this is up to the side contact to the in the Lateral frame of the frame in the closed position moved up. To lock the sliding sash to the frame, the in the closed position of adjacent parts of the frame and the closing sash locking elements are present. On the frame it is usually a locking bolt in the form of a head bolt whose head has larger dimensions, at least in the horizontal direction than the shaft adjoining the frame. On the sliding sash the corresponding locking element is a strike plate with a keyhole-shaped recess in which the clear width of one section to the dimensions of the head of the locking bolt and the other part are matched to the dimensions of the shaft. These sliding panels are between the rollers and the actual sliding sash has a lifting device which is generally operated by hand. Means

this lifting device, the sliding sash is lowered in the closed position, so that the head of the locking bolt from Surface section of the recess with the larger clear width is lowered to the surface section with the smaller clear width and thereby the sliding sash is locked to the frame frame. To open the sliding sash, it must first be raised again in order to then be pushed away on the rollers or, more precisely, rolled away. Because of this twofold movement the sliding movement and the lifting movement, these doors and windows are referred to as lift and slide doors or lift and slide windows.

The lowering movement has, in addition to the locking, the other Sense that there is a relative movement between the lower edge of the sliding sash and the threshold profile with the running rail, through which 'a sealing element which is generally arranged on the sliding sash rests in a sealing manner on an opposite surface of the threshold profile. The seal on the vertical edge of the Sliding sash takes place by means of an elastic sealing element, which when closing the sliding sash is attached to a corresponding counter surface of the frame frame creates a seal. During the lifting movement of the sliding sash for the locking must this vertical sealing element necessarily perform a relative movement with respect to the frame. Because this relative movement takes place under a certain contact pressure between the sealing element and the frame, the sealing element is subject to signs of wear. At the top of the sliding sash is a Sliding seal available. Since this is constantly in engagement, it causes every sliding movement of the sliding sash corresponding frictional forces that have to be overcome.

A very complex process is required for the lifting movement of the sliding sash Lifting device required, which for actuation either requires considerable physical strength or very long actuating levers requires a correspondingly large actuation path. The adjustment movements of the adjustment device must range from the usual location of the actuating lever via transmission elements to to the lower edge of the sliding sash and from there over the entire

Transfer the length of the sliding sash to the individual lifting elements distributed along the lower edge of the sliding sash. These transmission elements and lifting elements each contain according to their design a larger number of articulated levers, push and pull rods and / or curved tracks and moved along them Guide pin. All parts of this lifting device must be made so strong that they may be very able to cope with considerable weight of the sliding sash. The entire lifting device is accordingly very expensive.

The invention is based on the object of a fitting for To create sliding doors and windows that are less expensive to manufacture and that are easier to operate.

This object is achieved by a fitting with the features specified in the claim.

in that the sealing elements are provided with their own actuating device by means of which they are moved once into a sealing position and once into a release position can, the sliding sash can be moved in the release position of the sealing elements free of frictional forces. This sliding sash is therefore very easy to move. The sliding door is reliable in the sealing position of the sealing elements sealed. Because the sealing elements are operated independently, the sliding sash itself no longer has to be raised and lowered. The rollers are on the sliding sash fixedly arranged, at least for the axis of the rocker bearing of the carriage, if the rollers are on in pairs such carriages are arranged to effect an even distribution of the load on all rollers. The actuation forces for the sealing elements are many times less than for a lifting movement of the sliding sash. As a result, the operation of the sliding door is overall considerably easier than with the known lift & slide sashes. This also applies to the locking of the sliding sash against the frame, for which only

lent still a form fit between the locking elements must be made or, conversely, canceled without the The sliding sash must be lowered or raised.

In one embodiment of the fitting according to claim 2, the Occurrence of unidirectional sealing forces avoided, so that when the sealing elements are arranged on the obscure edge of the Sliding sash and with horizontal alignment of the same heavy sliding sash is left in its vertical position, in which its center of gravity is exactly above the rollers. With an "embodiment of the fitting according to claim 3 or 5 becomes a relatively simple and cheap to manufacture and Easy to assemble adjustment device created for the sealing elements. A further development of the fitting of Claim 3 according to claim 4 results in an actuating device which can be produced simply and cheaply, for example from extruded profiles, and which is only sufficiently wide and for installation deep groove in which it can be easily installed. at An embodiment of the fitting according to claim 6 eliminates the need for a separate actuating element for the adjusting device the sealing elements. With a further development of the fitting according to claim 7, it is possible to already then on the sliding sash To lock the frame securely when the sealing elements have not yet reached their sealing position. This enables gap ventilation when the sliding sash is locked. Through this in turn, separate ventilation elements including their actuating elements can be saved and still a good one Room ventilation can be achieved.

In the following the invention with reference to one in the drawings illustrated embodiment of the fitting on a Sliding door explained in more detail, which applies mutatis mutandis to the use of a sliding window.

The sliding door shown in FIGS. 1 and 2 are in one Frame 11 a fixed wing 12 and a sliding one Wing 13 arranged. The sliding wing is referred to as sliding wing 13 for short in the usual way.

The frame 11 is made of a threshold profile 14, from an upper one Frame 15 and composed of two side frames 16 and 17 in the usual way. The fixed wing 12 is also in the usual way from four profile sections made of wood, plastic

and / or assembled in light metal. There's a pane of glass inside 18 inserted and held in place with holding rods 19, which are shown in known way with tongue and groove connections attached to the wing IZ are. The wing 12 is permanently installed in the frame 11, wherein he on the three sides on which he rests on the frame 11, means Sealing strips 21 and 22 is sealed.

The sliding sash 13 is in its main parts in a similar manner

built and equipped with a pane of glass 23, which in turn is held by means of retaining rods 24 on the sliding sash.

On the threshold profile 14 of the frame 11 is in the plane in which the Sliding sash 13 is arranged, a running rail 25 is formed, which serves as a guide rail for the sliding sash 13 at the same time. In this level, as far as possible with the Schwerpurkts level of the sliding sash 13 should match, a plurality of rollers 26 are arranged on it. Two of these barrel rolls 26 are on rotatably mounted on a carriage 27, which in turn is mounted in a bearing housing 29 by means of a rocker mount 28 (Fig. 10). The bearing housing 29 is arranged in a longitudinally continuous groove 31 of the lower wing profile 32 and attached.

A guide housing 33 is connected to the bearing housing 29 and is made in one piece with it. The guide housing 33 is used a sealing element 34 as a guide and at the same time takes the parts of an adjusting device 35 for the sealing element 34

The sealing element 34 is a length of a shape elastic Sealing profile made of a rubber-elastic material. The sealing element 34 is provided with a groove 36 with which it is attached to a strip-shaped holder 37. at If necessary, both parts can also be glued together. The holder 37 also serves as part of the adjusting device 35.

In addition to the holder 37, the adjusting device 35 has an actuating strip 38, several guide pins 39 and several Actuating pin 41 on.

The actuating bar 38 has a U-shaped cross section and is thus arranged twice, so to speak. The space 42 between its two profile thighs is in its clear width matched to the thickness of the holder 37 in such a way that the actuating strip 3B also acts as a lateral guide for the holder 37 forms. The guide housing 33 has a C-shaped cross section. The outer shape and the outer dimensions of the actuating strip 38 are matched to the interior of the guide housing 33 so that the latter forms a guide for the actuating strip 38 both in the lateral and in the vertical direction. Through this Cross-sectional design of the interacting parts of the adjusting device 35 are advantageously unnecessary other guide elements.

In the vicinity of one of the two ends of the guide housing 33 there is a cylindrical through hole 43, each one of the guide pins 39 receives. In the same vertical plane in which the guide pins 39 are located on the guide housing 33, the holder 37 is each with a vertical one Guide slot 44 is provided, the clear width of which is matched to the diameter of the guide pin 39 and its clearance Height at least equal to the vertical path of movement of the holder 37 including the dimensions of the guide pin 39 is. The guide slots 44 form the guide tracks for the sealing element 34 for its perpendicular movement between a Release position and a sealing position. In the area of the guide pin 39 there are two long round ones on the actuating bar 38 Recesses 45 are present, the clear height and clear length of which are at least the same, better somewhat larger than the relative The movement space of the guide pin 39 is so that the actuating strip 38 to and fro in its guide in the guide housing 33 can be moved without touching the guide pin 39. The actuating pins 41 are over the entire length of the holder

and the actuating strip 38 arranged evenly distributed. she sit / Rn each in a cylindrical through hole 46 of the retainer strip 38. Their length is at most the same, better a little smaller than the width of the actuation bar 3Θ, so that they on the one hand when the actuating strip 38 is displaced the inside of the guide housing 33 and on the other hand are secured against falling out by the guide housing 33. In the area of each actuating pin 41 is on Holder 37 each one B e t 81 i π ι 'η π s r r h 1 ϊ 17 47 wnrhanden. its light Width is matched to the diameter of the actuating pin 41 while maintaining a running game. The longitudinal axis of the actuating slots 47 closes with the direction of adjustment of the actuating strip 38 as well as with the adjustment direction of the sealing element 34 an angle. Since the actuation bar 38 in Is adjusted in the direction of its longitudinal extension and there the sealing element 34 on the holder 37 through the guide slots 44 transversely to its longitudinal extension, the actuation slots 47 are relative to the longitudinal extension of the holder 37 aligned obliquely. The angle of inclination with respect to the longitudinal extension depends on what is desired or required Stroke for the sealing element 34 and according to the possible adjustment path of the actuating strip 38. Because of this adjustment movement is the actuating strip 38 is at least shorter by the adjustment path than the lower wing profile 32. The sealing element 34 and in general In contrast, its holder 37 also have at least approximately the same length as the sliding sash 13.

At the threshold profile 14 of the frame 11 is in a certain lateral distance to the running rail 25 in the alignment of the Movement plane of the sealing element 34 a contact surface 48 for the sealing element 34 is arranged or formed. This contact surface 48 is at least approximately horizontally aligned and either smooth or provided with a cross-sectional profile, which is matched to the cross-sectional profile of the sealing element 34.

Two sealing elements 51 and 52 are arranged along the upper wing profile 49. They have the same cross-sectional profile as the sealing element 34. They are also connected to a strip-shaped holder 53 and 54, respectively. The two holders 53 and 54 are arranged parallel to one another in the same plane along the upper edge of the upper wing profile 49. They are located on the top of the guide housing 55, the cross-sectional profile at least approximately the Gestslt Sinß s ^u! Üü! BtriechRn trapezium · whose qrööere parallel side is open. In the upper wall 56 of the guide housing 55 there are a number of guide slots 57 for each holder 53 and 54, which are aligned in the direction of adjustment of the sealing elements 51 and 52, namely transversely to the longitudinal extension of the sealing elements 51 and 52 and the guide housing 55 The sealing elements 52 and 52 and their holders 53 and 54 serve a number of guide pins 58 corresponding to the number of guide slots 57. They are designed as rivet bolts, which are riveted with their rivet shank 59 to the associated holder 53 and 54, respectively.

The adjusting device 61 has a flat actuating strip on. This is arranged on the inside of the guide housing 55 on the underside of the upper wall 56. The operating bar 62 is laterally of the two side walls 63 and 64 of the Guide housing 55 out. The actuating strip 62 has an actuating slot in each case in the region of one of the guide pins 58 65, which is oriented so that its longitudinal direction with both the adjustment direction of the holder 53 and 54 as also forms an angle with the direction of adjustment of the actuating strip 62.

The guide pins 58 are made so long that they extend from the holders 53 and 54 not only through the guide slots in the upper wall 56, but also through the actuating slots 65 in the actuating strip 62 (Fig. 8). The guide pins 58 thus also serve as actuation pins of the adjustment device 61. As in FIG. 8

- 10 -

As can be seen, the guide and actuating pins 58 are formed at their free-standing end in the manner of a collar bolt. The collar 66 present at the free end forms a shoulder for two races 67 which are arranged one behind the other on the shaft of the guide and actuating pin 58 in the axial direction. The lower race 6? has at least approximately the same height as the actuating bar 67 .. The upper race 61 has at least approximately the same height as the upper wall 56 of the guide housing 55. The two races 61 are matched to the shaft diameter and the shaft length of the guide and actuation bolt 58 , because there is a running game on all sides. When the actuating bar 62 moves relative to the guide housing 55, the lower race 61 rolls on one wall of the actuation slot 65 and the upper race on one wall of the guide slot 57, thereby causing an adjustment movement of the holder 53 or 54. The equipment with races is of course also with the guide pin §) AND WITH THE actuation pin 41 possible. Only the clear width of the guide slots 44 and the actuation slots 47 have to be adapted.

The guide housing 55 is connected to the upper wing profile 49 in a manner not shown. The width dimensions the two holders 53 and 54 are matched to the cross-sectional shape and the dimensions of the upper frame 15 of the frame 11, that their in the sealing position on each one contact surface 68 or 65 of a profile part of the upper frame 15 of the frame 11 sealing abut and are withdrawn from it in the release position to such an extent that the sliding sash 13 can be moved freely.

As can be seen from FIG. 10, the adjusting devices 35 coupled to the lower wing profile 32 and the adjusting device 61 to the upper wing profile 49 with a conventional locking device 71 with locking rods 72, namely each via a corner deflection 73 and by means of an actuation linkage 74. This actuation linkage 74 is adjustably connected to the relevant actuation guide 38 and 62, respectively.

The locking device 71 of the sliding sash 13 and the Actuating devices 35 and 61 are to be adjusted to one another in such a way that, on the one hand, the locking of the sliding sash 13 takes place completely and on the other hand the sealing elements their Reach sealing position. This coordination is facilitated by a certain transverse elasticity of the sealing elements.

An advantageous modification of the fitting results from that the locking device 71 of the sliding sash 13 is designed and arranged with all its parts so that after To achieve a complete form fit of the associated locking elements, a further actuation path or adjustment path is possible. Then the adjustment devices 35 and 61 are set so that the sealing elements have not yet reached their sealing position, but rather themselves are still largely in the release position when the locking device 71 is already in the locking position has reached, and that only when the locking device 71 is further actuated, the sealing elements are moved further into their sealing position. With such a modification of the Fitting is also possible when the sliding sash 13 is closed and locked.
