Description

r r. ,. *or.t 2371 326 .. .. FITTING FOR SLIDING DOORS

ibis invention relates to a slide fitting for a slide module, in particular a sliding door, in accordance with the main subject of Claim 1.

Fittings for sliding doors normally comprise two or several rollers mounted with holders on a sliding door, which roll on a common slide rail. The slide rail is mounted on a wall component and usually extends from above a cross-beam of a door-frame. At both ends of the sliding door's travel there are mounted, in its closed 10 and in its open position, stops which restrict the slide travel.

In order to facilitate setting of the door panel, the rollers are heightadjustable, i.e. they are mounted on the holders with vertical adjustment. Fittings with height-

adjustable rollers are known, for example, from documents DE 299 01 644 U1 and 15 DE 31 48 024 Al. It is disclosed by the latter document that the shahs of the rollers are mounted in the corresponding holders by means of eccentric discs. A further holder is known from DE 297 23 164 U1, where a setting device is also envisaged perpendicular to the plane of the door panel.

20 The purpose of this invention is to improve facilities for adjustment of known slide fittings. This objective is achieved under the invention with a slide fitting for a sliding component, with particular reference to a sliding door, by means of the 25 characteristics of Claim 1. Therein, the slide fitting under the invention exhibits at least one holder which can be mounted on the module, on which there is fastened in an adjustable arrangement a roller in a vertical plane and in its axis of rotation.

Furthermore, there is envisaged a fastener with a bearing pin and a mounting pin in a position eccentric to it, which has rotary and axial adjustment in a pick-up on the 30 holder, and can be locked in any desired position, in which context the roller is held in an arrangement permitting rotation on the bearing pin.

Under the invention, the roller - which is mounted with height adjustment - has additional adjustment in addition to its spacing from the plane of the door panel, and the fitting enables adjustment of the distance between the door panel and the wall upon which the fitting's slide rail is mounted. Accordingly, it is possible not only to 5 adjust the spacing between the running surface of the roller and the sliding module such as a sliding door, such that - for example - the gap between the lower edge of the sliding door and the surface of the floor beneath it can be adjusted, but it is also possible to set the gap between the door panel and the door frame such that, for example, it is possible to achieve satisfactory sealing against draught air, for example 10 by means of an all-round brush-type seal on the door frame against which the closed door panel will rest.

The roller is ideally made such as to provide for continuous adjustment in the vertical and axial planes.

The mounting section is characterized in particular by a mounting pin which can be locked in various rotary positions in a cylindrical, pick-up by means of which it is inserted in the holder. In order to achieve axial adjustment, the mounting pin can be adjusted in the axial plane within its pick-up, furthermore. In order reliably to 20 transfer adequately strong loading capacity from the pick-up to the mounting pin, it must be ensured that there is adequate contact area between the mounting pin and the pick-up. This can be achieved by forming the holder from a round- section bar which has holes drilled through its diameter in order to provide a pick-up hole. The mounting pin is inserted into the pick-up hole such that it protrudes from the side of 25 the holder opposite to the roller. By this means it is assured that the contact area does not become any less, even if the mounting pin experiences displacement in the axial plane. As described below, for aesthetic reasons a large number of the slide fitting's 30 components are made from sections of cylindrical bars, rods or tubes. This produces a technical/functional aesthetic impression which is characterized by cylindrical

V components. Accordingly, the cylindrical mounting pin of the fastener can be inserted into a cylindrical pick-up hole in a rod-shaped cylindrical holder which extends vertically. A threaded hole which extends at right angles to the pick-up hole accommodates a pinch-bolt by means of which the mounting pin can be reliably 5 locked in any desired rotary position or axial position. Since the bearing pin is eccentric in relation to the roller on the mounting pin, it is possible to adjust the height of the roller in relation to the holder, by rotating the fastener. Ibe distance between the door panel and the wall can be set by axial adjustment of the mounting pin in the pick-up hole.

Ideally, the fittings system comprises a locking device which prevents the roller from jumping out of the slide rail. Usually, Me roller exhibits a profile surface which follows the curved peripheral surface of the slide rail which is mainly of cylindrical-

rod shape. At a close spacing below the guide rail, a locking device which is 15 mounted on to the holder will extend. If the sliding door is raised or if it is moved against one stop or the other at high speed, the locking device will prevent the roller from jumping off the slide rail.

Since the slide rail is between the roller and the locking device which engages on the 20 slide rail at a close spacing on its underneath, the locking device itself should also be height-adjustable in its mounting on the holder. This is achieved ideally by similar means, whereby the roller is mounted on the holder. The locking device is made up of a locking pin which has a rotary, lockable mounting in a pick-up which is eccentric in relation to the locking pin. The pick-up is in turn ideally configured by a 25 pick-up hole in the holder, in which context the locking pin is mounted in the pick-up hole with a correspondingly shaped mounting pin which is eccentric to the longitudinal axis of the locking pin.

In tom, a pinch-bolt which is screwed into a threaded hole provides for locking of the 30 locking pin. The height of the locking pin which is eccentric to the mounting pin is set by adjustment of a given rotary position.

r:... 1-.-

. Likewise, the facility of axial adjustment of the locking device is advantageous in order for it to be adjusted for purposes of axial offset of the roller. For axial offset of the locking device, its mounting pin ideally possesses the facility of axial adjustment 5 whereby it is held in a pick-up hole and entirely protrudes through it.

The fittings system also comprises at least one stop, ideally two stops, in order to limit the slide travel of the fitting and accordingly that of the module which is mounted by the fitting on the guide rail. The stop can be connected by any desired 10 means in a rigid mounting with the wall or with the door lintel on which the slide rail is mounted. Ideally, the stop is mounted on the slide rail. In particular, the stops are ideally mounted in a longitudinally-adjustable arrangement on the slide rail such that the slide travel of the sliding door can be set as desired.

15 The stops are ideally configured such that at the end of the slide travel of the stop there arises contact with the holder in an area which is at the same height as the slide rail. In other words, the stop presses against a contact point on the holder which is at or close to a horizontal plane which also relates to the slide rail's longitudinal axis.

The eventuality of the stop contacting the holder rather than the roller is prevented by 20 having the roller bearing and - in particular - the eccentric mounting of the roller loaded with the corresponding stop forces.

Ideally, the stop exhibits a contact piece which has a sprung mounting on the slide rail. If the stop is made in the form of a cylindrical bar, then - for example - the 25 contact piece can be mounted on a cylindrical- form guide bar which is inserted into a cylindrical-form guide tube of the stop. In the cylindrical hole of the guide tube, there is also arranged a helical spring which enables spring-loading of the contact piece. In addition, the contact piece itself can be configured for elasticity and can, for example, consist of a natural or synthetic rubber material. The guide tube of the stop 30 is connected with the slide rail by means of a mainly cylindrical connecting component, in which context this connecting component exhibits.two holes through

which there protrude firstly the slide rail and secondly the guide tube, and where both the guide tube and the slide rail are held in the corresponding holes by means of a pinch-bolt. 5 Ideally, all of the structural parts of the fittings system should consist of cylindrical bars, tubes, sleeves etc. There are aesthetic advantages in this consistent configuration of components.

Preferably, then the slide rail consists of a cylindrical tube which extends 10 horizontally. The holder consists of a vertical, cylindrical rod. The mounting components by means of which the holder is mounted on the sliding door, ideally a glass sliding door, are cylindrical mounting stubs. A globally harmonious visual impression is obtained both by the glass of the glass sliding door and also from the reverse side, thanks to the essentially cylindrical components.

Ideally, at right angles to the longitudinal axis of the holder and the right angles to the plane of the sliding door itself, there are arranged cylindrical pick-up holes in the holder, in which there is held the mounting pin for the roller and a mounting pin which is integrally connected with the mounting pin. Both of the mounting pins can 20 protrude from the bar-shaped holder on the slide opposite to the sliding door.

The stop, furthermore, is ideally made in the form of a cylinder and is arranged flush with the slide rail which is in the shape of a cylindrical bar. The sprung contact piece is mounted on a guide bar which can be slid into the cylindrical hole of the guide 25 tube of the stop against the force of a helical spring.

In most instances, each door panel of a sliding door is equipped with 2 rollers which are mounted on the second door panel by means of a holder. These holders can be connected by means of a cylindrical connecting rod which extends mainly parallel to 30 the slide rail. The cylindrical connecting rod in the process protrudes through cylindrical through-holes in both holders.

-.r r .:^ . .., A specification form of the invention is described below with reference to the

attached drawings. The drawings are set out as follows: 5 Figure 1: a diagrammatic front view of the slide fitting under the invention; Figure 2: a diagrammatic rear view of the slide fitting under the invention; Figure 3: a rear view of the slide fitting from Figures 1 and 2; Figure 4: a lateral cutaway view of the slide fitting along the sightline of lV- lV in Figure 3; 10 Figure S: a plan view of the slide fitting; Figure 6: a plane frontal view of the slide fitting; Figure 7: a diagrammatic view of a roller of the slide fitting; Figure 8: a cutaway view of the roller from Figure 7; Figure 9: an exploded view of the roller from Figures 7 and 8; 15 Figure 10: a diagrammatic view of a locking device of the slide fitting; Figure 11: a frontal view of a stop for the slide Tiffing under the invention; Figure 12: a side view ofthe stop from Figure 10; Figure 13: a plan view ofthe stop from Figure 10; Figure 14: a diagrammatic view ofthe stop Mom Figure 10; 20 Figure IS: a cutaway view of the guide tube with the contact piece mounted on it in a sprung arrangement; Figure 16: a cutaway view of the connecting component; and Figure 17: an exploded view of all components.

25 Figures 1 and 2 each illustrate a diagrammatic overview of a slide fitting under the invention. Figure 1 shows We frontal view, i.e. the view from the middle of the compartment enclosed by sliding door 1 against the wall (not illustrated in Figure 1), which is 30 enclosed by sliding door 1.

^ - i. :. : Figure 2 illustrates the rear view, i.e. a diagram of the slide fitting under the invention, seen from the wall against which it is mounted.

The slide fitting fulfils the function of mounting of a door panel 1 of the sliding door, 5 ideally made of glass. On door panel 1 there are mounted - by means of two holders 2, two rollers 3 which exhibit a concave-profile running surface 4. The two rollers 3 run on a slide rail 5. The slide rail 5 is made up of a cylindrical-form tube which is connected by means of screwed fasteners (refer reference mark 6 in Figure 4) with a section of wall (refer reference mark 7 in Figure 4).

For aesthetic reasons, virtually all of the components of the slide fitting are made up of cylindrical components. In order to increase the robustness of the fitting, the two holders 2, which consist of cylindrical bars which extend vertically, are interconnected via a connecting rod 8. In this context both of the holders 2 exhibit a 15 pick- up hole which extends perpendicular to its vertical longitudinal access and parallel with the plane of the door panel. Connecting rod 8 is firmly clamped by a pinch-bolt 9 in the two pick-up holes.

At the lower section of each cylindrical-rod shaped holder 2 there is mounted glass 20 door panel 1 by means of two mounting stubs 10 which also exhibit a round external contour. And door panel 1 for this purpose exhibits two holes (not illustrated), through which there protrude screws which are screwed through mounting stubs 10 into threaded holes (also not illustrated) in the holders 2. The screw-heads 11 of these screws rest against the reverse side of glass door panel 1 and can be seen in 25 Figure 2.

Against the two holders 2, below slide rail 5 there are arranged locking devices 12 which prevent the two rollers 3 jumping off slice rail 5.

30 Under the invention, rollers 3 and locking devices 12 are mounted on holders 2 in an arrangement with adjustment both for height and parallel to the direction of the axis

r - r ^, An, - -

of rotation of rollers 3. This is apparent particularly from Figures 7-10 of the drawings. Figure 7 illustrates a roller 3 envisaged for mounting on holder 2.

However, roller 3 has a rotary mounting on fastener 14 by means of two roller 5 bearings 13, mainly consisting of two pins 15 and 16 which are eccentric to each other, and which are separated from each other by a circular disk section 17. The shorter bearing pin 15 fulfils the function of picking up the two roller bearings 13 (refer Figure 8). It exhibits a threaded hole for picking up a mounting screw 18 by means of which a cover plate 19 can be mounted which covers a lateral surface of lo roller 3. After assembly of the individual components of the roller arrangement as visible in Figure 9 with the unit illustrated in Figures 7 and 8, mounting pin 16 of fastener 14 protrudes entirely through a pick-up hole in the upper end-section of fastener 2 (refer Figures 1 and 2) such that the end of mounting pin 16 protrudes from out of fastener 2 on the side opposite roller 3. Mounting pin 16 is locked in its rotary 1 S position and in its axial position within the pick-up hole of fastener 2 by a pinch-bolt 20 which is screwed in from the upper end surface of fastener 2 into a threaded hole which runs in the longitudinal axis of fastener 2.

It can be seen that by rotation of mounting pin 16 in its pick-up fastener 2 it is 20 possible to adjust the height of the axis of rotation of roller 3 in relation to fastener 2 and thus in relation to door panel 1. By this means, the horizontal alignment of door panel 1 and a gap between the lower edge of door panel 1 and the floor can be adjusted. This can be done by a single person unaided. This person can mount the door panel together with the two rollers 3 on slide rail 5, in which context the above 25 mentioned locking devices 12 are not yet abutting against slide rail 5. By releasing pinch-bolt 20 and subsequently by rotating mounting pins 16 in their pick-ups, it is possible to adjust the spacing of bearing pin IS in relation to door panel 1 and thus also the desired height of door panel 1. At the same time, by axial movement of mounting pin 16 within its pick-up, it is possible to adjust the spacing of the door 30 panel in relation to the wall against which it is mounted. By subsequent tightening of pinch-bolt 20, mounting pin 16 of the fastener is established in its rotary position and

r : _ _

in its axial position. Since mounting pin 16 protrudes entirely and throughout its range of adjustment through the pick-up hole in bar-shaped fastener 2 and its free end protrudes out from fastener 2 on the side opposite to roller 3, there is no change in the amount of contact surface between mounting pin 16 and the pick-up as the result 5 of axial displacement of mounting pin 16 in its pick-up. A secure force lock can be achieved in every envisaged adjusunent position, thanks to the pinchbolt.

Next, locking devices 12 can be arranged and locked at a close spacing from the underneath of rail 5. In order to make it possible to achieve an adequately small 10 spacing at all setting positions of rollers 3, between the lower surface of slide rail 5 and locking devices 12, it is also made adjustable for height and in the axial direction, in accordance with the illustration in Figure 10. Locking device 12 comprises a locking pin 21 and a mounting pin 22 which is integrally connected with locking pin 21 and is eccentric in relation to it. Locking pin 22 is in tum held in a 15 cylindrical pick-up hole in fastener 2 and extends mainly parallel to mounting pin 16 for roller 3. Furthermore, mounting pin 22 of locking device 12 protrudes from mounting device 2 on the side opposite roller 3 and is fixed by means of a pinch-bolt 23 (refer Figure 1) which is screwed into a lateral threaded hole of fastener 2 in which context the threaded hole extends mainly parallel to slide rail 5 and into which 20 there gives the pick-up hole for mounting pin 22 of locking devices 12.

After setting of rollers 3, both of locking pins 21 can be adjusted by rotation of their respective mounting pins 22 and subsequently fixed by means of pinch-bolt 23 such as to achieve an adequately close gap between locking pin 21 and the underneath of 25 slide rail 5. Upon vigorous manoeuvnng of door panel 1 or if the slide fitting is run to its stop, locking devices 12 will exclude the risk that rollers 3 will jump off slide rail 5. Slide rail 5 is securely held in the curvature of concavesection running surface 4 of roller 3.

30 A further advantageous characteristic of the sliding fitting under the invention is stop 24, which is arranged at both ends of the slide travel for the sliding fitting.

r - e. _ . Stop 24 itself is configured mainly cylindrically and is connected with slide rail 5 by means of a likewise cylindrical connecting component 25. The details of the structural configuration of stop 24 and of its connecting component 25 are apparent 5 particularly from Figures 11 to 17. Connecting component 25 is, as mentioned, a cylindrical metal component and exhibits two holes 26, 27 which are parallel to each other and which extend at right angles to the cylindrical axis of connecting component 25. Hole 26 fulfils the function of picking up slide rail 5 (refer Figures 1 and 2, for example). One of the threaded holes 28, 29 which run in the axial plane of 10 cylindrical connecting component 25, of which one will give into hole 26 for slide rail 5 and secondly into hole 27 for connecting component 25, will respectively provide the function of accommodating a pinch-bolt 30 or 31 for locking of the component which is inserted into hole 26 or 27 of connecting component 25. Upon assembly, initially slide rail 5 is inserted into larger hole 26 and connecting 15 component 25 is locked approximately in the area of the required stop position, whereby threaded hole 28 which is located between two holes 26 and 27 has screwed into it pinch-bolt 30. Next, stop 24 is inserted into hole 27 and is locked in its desired position by means of second pinch-bolt 31.

20 Ideally, the axes of slide rail 5, of connecting component 25 and of stop 24 reside in a horizontal plane. The front end-face of stop 24 rests against one of the two fasteners 2 when the slide fitting is in an end position.

In order to prevent load peaks upon panning of fasteners 2 to their stops for sliding 25 door panel 1 against one of stops 24, contact piece 32 of stop 24 has a sprung configuration. It consists firstly of a material with the capacity for elastic deformation, ideally a natural or synthetic rubber. Secondly, contact piece 32 is connected under a sprung arrangement, and one which is elastic, for insertion with connecting component 25. For this purpose, stop 24 exhibits a guide tube 33, which 30 is enclosed unilaterally by an end-face 34, in which there is arranged an axial through-hole 35 (refer Figure 17).

A clamp bolt 36 protrudes through through-hole 35 and its screw head 37 rests against end-face 34. Clamp-bolt 36 is screwed at one end into a guide bar 38 into whose opposite end there is securely screwed contact piece 32. Guide rod 38 is held 5 with longitudinal sliding provision in cylindrical hole 39 of guide tube 33; Between the end of guide rod 38 which is within guide tube 33 and the inside of end-face 34 there is arranged a helical spring 40 which has a preloading of a certain degree in the off-load position of the stop (refer Figure 15) by means of clamp bolt 36. If an axial force lock is applied by tightening of a fastener 2 against contact piece 32 of a stop lO 24, then guide rod 38 is axially fed into a guide tube 33 against the force of helical spring 40, such as to provide spring resistance against the force lock.
