Description

The invention relates to a clamping fitting for clamping holding a sliding door.

Sliding doors are usually moved by means of one or two roller carriages along a running rail. For this purpose, various systems are known in which either the sliding door is attached via a clamping device with the roller carriage, or is connected via a hole in the door and with an associated screw with the roller carriage. Since the hole for the roller carriages is made in the factory of the manufacturer, there is no possibility on the construction site to adapt the door with the roller carriage the necessary conditions. Here is the problem of storage of the drilled doors, which leads for example in printed doors to many variants, as this is to be combined with left and right doors and the associated holes for the roller carriage and fastened by means of holes fittings.

Clamping devices have the disadvantage of creeping loss of clamping force, which sooner or later causes the door to fall out of the clamping device or sag. To prevent this, only the lighter doors are suspended by clamping, especially in glass doors, taking care that no sudden shocks or high accelerations act on the door. Furthermore, the clamp fitting is so oversized that the loss of clamping force is negligible in the lighter glass doors. Usually, however, these clamping fittings are designed only for a glass thickness, so that for any desired glass thickness and door size another clamping fitting must be used from the range. Again, the number of variants to be stored is very high.

The DE 10 2008 004 751 B3 describes a clamping fitting for a sliding glass door, which is adjustable in stages to different glass thicknesses. Two clamping plates each have an oppositely toothed coupling leg, which engage with each other. The legs coupled by the toothing form the pivot point of the power lever, with which the clamping fitting clamps the glass door. A fine adjustment is not possible with this clamp fitting. Another disadvantage is the arrangement of Befestigungslemente which press apart the clamping plates above the coupling legs, as this requires a massive version of the clamping plates. The running track covering the clamping fitting must therefore have a corresponding depth, which does not correspond to a modern filigree design.

It is an object of the invention to develop a clamping fitting in which the door does not need to be drilled and with a few components a variety of door sizes can be used.

The invention solves the problem by the teaching of claim 1; Further advantageous features of the invention are characterized by the subclaims.

According to the technical teaching of claim 1, the clamping fitting comprises a sword, a roller disposed on the sword, and a clamping gap for receiving the sliding door, wherein the clamping gap, a first adjustability is arranged, which is adjustable in stages according to the thickness of the sliding door. To prevent the creeping loss of clamping force, a second adjustability is arranged on the nip, which allows a stepless adjustment of the nip. This can be done an optimal adjustment of the clamping force to the size and weight of the door.

In a preferred embodiment, the nip is formed by a clamp mount and a clamp area. The clamping area is located at the lower part of the sword and clamped with the clamp mount the sliding door. In this case, the clamping bracket is L-shaped and has a short and a long leg. The assembly of the short leg on the clamping area by means of at least one connecting element, which simultaneously applies the clamping force on the sliding door. The long leg of the clamp holder acts clamped on the sliding door.

In an advantageous embodiment, the first adjustability is effected by a spacer element, which is arranged interchangeable between the clamping bracket and clamping area. Thus, a universal clamp fitting can be used for different thicknesses of sliding doors, since the first adjustment is made by the spacer element. It must therefore be stored only the spacer and an optionally longer connecting element to deliver a clamping fitting for all common glass thicknesses.

In this case, the at least one connecting element brings the clamping force, wherein the spacer element forms the pivot point of a lever. The spacer element is arranged on the short leg of the clamp, wherein the long leg applies the clamping force on the sliding door.

The second adjustability is formed by a clamping plate which is arranged on or in the clamping area. After the first setting of the nip by the spacer element and the tightening or the application of the clamping force on the long leg of the clamping bracket, the clamping force can be further increased, in which the clamping plate is pressed into the nip. This can be done continuously, so that a creeping loss of clamping force can be counteracted by the elastic deformation of the clamp and the clamping area. The strengthening of the clamping force by pushing out the clamping plate can be done at the initial assembly, but it can also be done during an annual inspection.

For moving the clamping plate in or out of the nip at least one pressure element is provided which can be actuated without dismantling the clamping impact.

In this case, the at least one pressure element is arranged in the clamping region, preferably integrated in the clamping region, so that there is an invisible solution for adjusting the clamping plate.

The pressure element is supported on a retaining plate, which is also arranged in the clamping area. This allows a connection between the pressure element and the clamping plate such that the clamping plate can not fall out of the nip after the mounting of the clamping.

In a preferred embodiment, the sword is designed as an elongate body having an upper suspension and a lower clamping region. In this case, the upper suspension and the clamping area may be integrally formed. On the upper suspension, the roller is mounted, where forms against the lower clamping portion of a part of the nip.

For covering the connecting elements, pressure elements and other screws, a cover is arranged on the back of the sword, which is detachably fastened by means of a magnet on the sword. It can thus be removed without tools and possible damage to the cover to adjust the pressure elements and thus to increase or decrease the clamping force.

According to an advantageous embodiment, the sliding door has at least one fitting for opening or closing, which is glued to the sliding door. Thus, the sliding door can be delivered without glass processing. There are no holes, cutouts or shapes needed that were otherwise needed for the carriage bracket and the handle fittings. The sliding door can thus be used basically for left or right version, which significantly reduces the storage and significantly reduces the cost of the sliding door.

So that a non-specialist can attach the fitting without tilting and absolutely congruent on both sides of the sliding door, a template is provided with the fitting on the sliding door can be aligned.

The invention will be explained in more detail with reference to a possible schematically illustrated embodiment. It shows:

1 a sliding door with a running rail;

2 : a first sectional drawing through the clamp fitting;

3 a second sectional drawing through the clamp fitting;

4 : a representation of a template.

The sliding door 1 to 1 is by means of two clamp fittings 2 . 2a on a running track 3 slidably guided. Each clamp fitting 2 . 2a has a device for clamping the sliding door 1 on, as well as a roller 24 on the track 3 is movable. The track 3 has at least two wall mounts 4 on, by means of which the installation takes place on a wall or ceiling. Furthermore, on or on the track 3 a stopper at each of its ends 5 arranged with the open or closed position of the sliding door 1 can be adjusted. In this embodiment, the sliding door 1 in closed position and thus closes a passage or a door opening. To operate the sliding door 1 this has a fitting 6 on, which is designed according to this embodiment as a grip shell. According to the invention the fitting 6 on the sliding door 1 glued on, leaving the sliding door 1 No holes or necessary glass processing - except for a possible decor by screen printing, sandblasting, etc. - needed. It can therefore be used for any door openings and used for left or right versions. The symmetrical arrangement of the decor also contributes to a universally applicable sliding door 1 to be able to use. To commute the sliding door 1 to avoid is in the bottom area a floor guide 7 arranged. The sliding door system thus includes a sliding door 1 , two clamp fittings 2 . 2a and a glue-on fitting 6 ,

The for gluing the fitting 6 provided template 30 is exemplary for a round grip shell in 4 shown. The stencil may be made of paper and will be along two predetermined fold lines 31 folded for the glass edges. Furthermore, the diameter d is cut out. The diameter d corresponds to the diameter of the grip shell, the distance Y of the edge of the sliding door is arranged. Instead of a diameter d, an oblong rectangle, possibly also with rounded edges or end face, can be made here, which serves as a template for a fitting with an elongate base area. Any shapes can be applied with the correspondingly shaped contour.

The fold lines have the distance X, the glass thickness of the sliding door 1 corresponds, such as 8 mm. The bottom edge of the template 30 is aligned with a distance Z from the lower edge of the sliding door, which may be for example 800 to 1000 mm. Thus, the template 30 on both sides of the sliding door 1 at the correct distance Z from the lower edge of the sliding door 1 be aligned. The on both horizontal sides of the template 30 arranged contour 32 is executed in this embodiment as an elongated rectangle. The contour 32 may be formed as an adhesive strip, which is the template 30 at the sliding door 1 attached. The bonding of the fittings 6 , in this embodiment, the grip shells, is thus considerably simplified, since the fittings 6 then from both sides absolutely congruent on the sliding door 1 can be aligned and glued.

The clamping fitting according to the invention 2 after the 2 and 3 essentially comprises a sword 10 , a mounted roller 24 , as well as a clamping area 10a in which a sliding door 1 between a clamping bracket 11 and a clamping plate 14 in a nip 11a is trapped. The sword 10 is designed as an elongated body, with an upper suspension 10b at which the caster 24 is stored, and a lower clamping area 10a , suspension 10b and clamping area 10a are arranged substantially in a longitudinal alignment, wherein the clamping area 10a may have a more massive cross-section than the suspension 10b because of the clamping area 10a a high bending moment due to the pinching of the sliding door 1 must record.

The roller 24 is by means of a warehouse 25 rotatably mounted. The warehouse 25 can do this with its inner diameter on a bearing mount 28 , For example, by pressing radially fixed. In the axial direction, the bearing 25 through at least one disc 27 fixed. The storage holder 28 can by means of fastening element 26 on the suspension 10b be attached. The roller 24 can be mounted one or more parts on the bearing bracket axially and radially.

At the clamping area 10a of the clamp 2 is a clamp holder 11 arranged the sliding door 1 against the clamping area 10a holding in place. The clamp holder 11 is designed L-shaped in this embodiment, wherein the shorter leg by means of at least one connecting element 13 at the clamping area 10a is mounted. Between clamping area 10a and clamp bracket 11 is in the field of attachment a spacer element 12 arranged, which is formed in this embodiment as a pin. The spacer element 12 is arranged interchangeably and depending on the thickness of the sliding door 1 replaced. With sliding doors 1 with greater thickness, it is therefore possible that the shorter leg of the clamp 11 not at the clamping area 10a directly abuts, but this example, 2 mm distance. The replaceable spacer element 12 forms together with the clamping bracket 11 , the clamping area 10a and the connecting element 13 a first adjustability of the nip 11a , which thus takes place in stages, according to the adaptation of the spacer elements 12 to the glass thickness.

In the longitudinal direction below the spacer element 12 this is at least one connecting element 13 arranged the clamping force on the surface of the sliding door 1 applies. The clamp holder acts here 11 as a one-sided lever, in which the spacer element 12 forms the fulcrum. The clamp holder 11 Although is also very solid, the bending moment to clamp the sliding door 1 Nevertheless, it deforms something anyway, so that the effective clamping force does not arrive punctiform at the end of the long leg, but due to a slight deformation flat in the sliding door 1 is initiated.

A second adjustability of the nip 11a is created by that on or in the clamping area 10a on the side of the clamping gap 11a an adjustable clamping plate 14 is arranged. The clamping plate 14 is in this embodiment in a corresponding opening or recess in the clamping area 10a let in and can by means of one or more pressure elements 17 from the surface of the clamping area 10a be moved out or in. This is another stepless adjustability of the nip 11a for pinching the sliding door 1 given.

Inside the nip 11a are each a glass protection on both sides 15 , so on the clamp bracket 11 as well as on the clamping plate 14 arranged. Also the front edge of a clamped sliding door 1 can through a glass protection 16 be protected, which is arranged on the inside of the short L-shaped leg. As previously mentioned, the clamping plate 14 by means of one or more pressure elements 17 in the clamping area 10a moved in or out. In this embodiment, two pressure elements 17 designed as a cheese head screw in the clamping plate 14 are screwed in. So that the clamping plate 14 can move, the pressure element must be 17 , here the cylinder head bolts, against the adjustment direction within the clamping area 10a support. On the back of the clamping area 10a For this purpose, a recess is arranged, in which a retaining plate 18 is used. Also this retaining plate 18 comes with the clamp area 10a connected or screwed. In the retaining plate 18 are holes 17a let in, by the adjustability of the clamping plate 14 through the pressure elements 17 is possible.

The installation of the clamp 2 can with the screwing or fixing the preassembled roller 24 by a fastener 26 on the suspension 10b respectively.

Then the mounting of the clamping plate takes place 14 by first the pressure elements 17 , so here the cylinder head bolts, in holes in the clamping area 10a be used. The threads of the pressure elements 17 now stand out of the hole. The pressure elements 17 are then secured from the rear by the retaining plate 18 with fasteners 19 at the clamping area 10a is attached. At the front of the clamping area 10a , so to the nip 11a down, the clamping plate becomes 14 with the pressure elements 17 screwed. These are in the retaining plate 18 two holes 17a arranged, through which a tool for adjusting the pressure elements 17 can be carried out. After sticking the glass protection 15 . 16 on the clamping plate 14 and on the clamp bracket 11 , the spacer element becomes 12 used and the clamp bracket 11 with the one or more fasteners 13 screwed. The clamp fittings 2 can now in the range of an upper end edge with the nip 11a on the sliding door 1 be plugged. The clamping force is then achieved by tightening the connecting elements 13 achieved. A further reinforcement of the clamping force can be achieved by adjusting the pressure elements 17 be achieved. The sliding door 1 with the two clamp fittings 2 . 2a can now over the rollers 24 on the track 3 be hung. A pre-assembled lift-out protection 20 with, for example, a rotatable roller can then below the track 3 on the suspension 10b by means of connecting element 21 to be assembled. A cover 23 disguises the entire back of the sword 10 so that the fastener 26 , the one or more fasteners 13 and the pressure elements 17 are not visible to the user of the door. A readjustment of the clamping stroke 1 in terms of clamping force requires the removal of the cover 23 , This is very simple in this embodiment and designed without tools by the cover 23 detachable by means of magnets 22 attached to the sword, with the magnets 22 can be used in corresponding holes.

A further improvement can be achieved by the glass protection 15 on the clamp bracket 11 rests, in the vertical direction from the nip 11a is arranged movable out. He has to be led and gets the contour of a double wedge with the cross-section of the clamp. That is, for opening the nip 11a The cross-section of the clamp bracket decreases 11 to, by getting thicker, and the cross section of the glass guard 15 decreases as it gets thinner. Should the clamping force give in due to the weight of the door, the sliding door will open 1 with the glass protection 15 try to get out of the nip 11a to move down. Due to the double wedge and the increasing thickness of the clamping bracket 11 becomes the nip 11a narrow, leaving the weight of the sliding door 1 to a certain extent becomes a reinforcing effect on the clamping force, since the wedge-shaped glass protection 15 on the wedge-shaped clamp 11 driving along.
