Description

The invention relates to a fitting set according to the preamble of claim 1.

Fittings of this kind belong for example by the EP 1 106 758 B1 already the state of the art. In the known fitting from the EP 1 106 758 B1 it is a panic lock or called panic bars or pushbar.

Conventional panic locks comprise an elongated box-like body attached to the side of the door panel which faces the closed space and which has a U-shaped cross-section as a retaining profile for receiving the profiled operating rod or actuator door handle. Two parallel transmission levers are rigidly coupled to the rod and hinged like a parallelogram in the box-like body. One of the levers is operatively connected to the lock for closing the wing via a transmission element. This is done, for example, in that a coaxial with a follower of a lock arranged and provided with a polygonal gear is provided with this, which is associated with its toothing a rack. The rack is longitudinally slidably mounted in the box-shaped body and is connected to the lever or levers so that the rack is longitudinally displaced when the lever is depressed.

One problem with panic locks is that their length should be adjusted to the width of the wing to which they are to be attached. In addition, the known design is designed comparatively expensive. The levers consist of elaborately formed stamped and bent parts, whose connections are made by means of special axes, which on the other hand have an abutment on the actuating rod on the one hand and a bearing part on the wing on the other hand.

The invention is therefore an object of the invention to provide a fitting that allows a simple construction reliable operation and can also be easily adapted to the wing.

To solve this problem, the invention provides that the lever is fixed at one end to the actuating rod and at its other end to a carriage is pivotally mounted, which supports the lever in a guide groove of the retaining profile perpendicular to the wing plane. This greatly simplifies the mechanics. The elaborate bearings are replaced by simple assembly. In addition, the fastening profile, the insert body, the cover and the connecting rod of the carriage by means of vertical cuts are easy to adapt and to couple with each other.

Further advantageous embodiments will become apparent from the claims 2 to 9.

Thus, it is provided that the carriage is supported by at least one roller in the guide groove and that the pivot axis of the lever and the roller are identical. As a result, on the one hand ensures the storage of the lever in the guide groove and at the same time the carriage in the guide groove mounted friction.

If the retaining profile consists of a substantially U-shaped profile, this causes a simple design of the retaining profile, since this consists essentially of the required for guiding the carriage groove.

Furthermore, it can be provided that a slider is attached to the carriage, which is adapted to the guide groove. The carriage can be simplified in that the lateral guidance is effected by the slider. Thus, the carriage can be made with less care, without fear of an increased level of friction.

It is also advantageous if two levers are provided, which are mounted near the end of the holding profile. Although it can be provided that only one lever is mounted in the immediate vicinity of the castle. The remote from the end of the profile is then stored in a guide perpendicular to the wing plane and movable against a restoring force storage device. However, it is simpler to provide an identical second lever.

To ensure a simple construction, the stationary mounting of the lever on the wing can be done via the profile.

It is also advantageous if the lever is made on the profile by means of a fastening profile which is fixed in a groove of the actuating rod.

This allows a very simple attachment to the operating rod. There is no need to introduce axes in guides of the profile of the actuating rod and also eliminates the otherwise necessary axial fixing of the same on the lever. The lever is pivotally attached to the mounting profile and can then be inserted into the groove of the actuating rod.

Another advantage is given by the fact that the actuating rod is designed as an insert body, which is encompassed by a cover and which in turn engages over the retaining profile. This makes it possible that the holding profile can be produced as a favorable extruded profile, on the surface only small claims must be made. The cover can in turn be made of a high quality material and treated arbitrarily surfaces.

Finally, it is also envisaged that a transversely extending groove is provided on the fastening profile, into which a locking member effective as a fixing plate is inserted, which is attachable to the insert body. This arrangement makes it possible to fix the mounting profile easily and accurately on the support profile.

In the Fig. 1 the fitting is generally provided with the reference numeral 1. The fitting 1 is an emergency opening or panic bar, with two support plates 2 and 3 ( Fig. 3 ) are attached to the spars of a door, not shown here. The carrier plates 2 and 3 are in the Fig. 1 and 2 covered by caps 4, 5. Between the support plates 2, 3, an actuating rod 6 is arranged. The actuating rod 6 can be shown in the FIGS. 1 and 2 take at least two positions. In the in Fig. 1 shown closure position, the actuating rod takes a maximum distance to the wing plane, which runs parallel to the support plates 2, 3. In the open position, however, the actuating rod 6 is displaced by a force acting in the direction of the arrow 7 in the direction of the wing plane. In this position, the wing is openable, as a near the support plate 2 attached and not shown here lock is placed in an open state.

The actuating rod 6 is provided at the end with two cover caps 8, 9 and with a cylindrical cover member 10 which encloses an insert body 11. The insert body 11 thereby forms a stable support, while the cover caps 8, 9 and the cover 10 can be easily adapted to the color characteristics of the door. The insert body 11 is closed at the end with fixing plates 12, 13, whose function will be explained.

The insert body 11 is corresponding to the Fig. 4 associated with a stationary holding profile 14, which consists of a substantially U-shaped profile bar, as will be explained in detail below.

In the Fig. 5 is in a side view of the fitting after Fig. 3 omitting the fixing plate 12 on the insert body 11 of the actuating rod 6 is shown. The insert body 11 is designed as an extruded profile and has a substantially cylindrical cross-section, with a U-shaped groove 15. In addition to clearances for weight reduction and two longitudinal holes 16 are provided which serve as abutment of mounting screws which hold the fixing plates 12, 13 on the insert body. The fixing plates 12, 13 are shown in the Fig. 6 , which the fitting 1 after Fig. 5 in a rear view with the fixing plate shows, provided with open-edged recesses 17 and holes 18 which are mounted congruent to the groove 15 and the holes 16 of the insert body 11. On the insert body 11, a further undercut groove 20 is provided in the bottom 19 of the groove 15, which by two L-facing or facing. conversely L-shaped webs 21, 22 is formed. This results in the side next to the webs 21, 22 narrow grooves 21 ', 22'. These find as well as the webs 21, 22 a corresponding shape in the fixing plate 12 and 13th

The fixing plate 12, 13 consists of a thin-walled sheet metal section and can be e.g. Produce cost by punching.

Is according to the Fig. 7 removed the actuating rod, it is clear that in the groove 20 a fastening profile 23 is seated, which has a complementary shape to the groove 20.

In the cut after Fig. 8 the structure becomes clearer. The actuating rod 6, consisting of the insert body 11 and the cover 10 is limited by the cap 9 - of which only one outer edge is visible here - the end. The cover 10 engages in the exemplary embodiment with two bends 24 in the groove 15 of the insert body 11 a. In the groove 15 also projects the retaining profile 14, the free U-legs 25 have at their ends 26 outward Umkantungen 27 by 180 °. The folded edge 27 thereby forms a transverse to the opening of the holding profile 14 directed stop edge 28 or collar on which the bends 24 abut. As a result, the end position of the opening movement of Operating rod 6 limited. In addition, it is avoided that a sharp and injury risk end edge arises when not yet mounted insert body 11 and operating rod 6.

In the guide groove 29 formed by the U-section of the retaining profile 14, a carriage 30 is guided, which in conjunction with the FIGS. 9 and 10 is described. The carriage 30 is coupled to a sliding body 31, the dimension of which is adapted to the clear width of the guide groove 29, thereby ensuring guidance of the carriage 30 along the holding profile 14. On the carriage 30, a lever 32 is pivotally mounted. The lever 32 consists of two lever arms 33, 34 which are spaced at one end by the mounting profile 23 and the other end by a roller 35 from each other. This embodiment avoids the formation of the lever from a complicated stamped and bent part, without that there are significant limitations in the load capacity. The lever arms 33, 34 are identical, so that it can come to a cost-effective production by punching due to the higher number of units, which is also favored by the fact that the lever arms 33, 34 have no offsets.

The lever 32 is drivingly connected via the carriage 30 and a coupling device 36 provided thereon with a push rod 37, which is guided longitudinally displaceably below the cover 38. The cover 38 is part of the support plate 2 and fixed on a spacer plate 39 of the support plate 2. The push rod 37 has a toothing not shown here or a driving cam, which is associated with a toothing or a cam of a rotatably mounted on the support plate 2 pinion or cam. If the push rod 37 is moved longitudinally, this also causes a rotation of the pinion or the cam disk. Coaxially to the pinion or the cam disk, a knob 40 is mounted on the cover 38. It is not visible that a polygonal shaft can be coupled to the pinion or the cam disk, which passes through a bore of the blade and drives the pinion or the cam disk with a nut of a lock.

Alternatively, instead of the above-described connecting element, a toothing can be provided on the push rod 37, which meshes with a pinion that engages via a polygonal pin in a follower of the lock.

As the Fig. 8 in conjunction with the FIGS. 9 and 10 shows, the lever 32 is supported on the roller 35 on the bottom 41 of the guide groove 29 from. In this case, the lever 32 is pivotally mounted in the roller 35 by the common pivot axis 42. If the lever 32 from the in Fig. 11 shown closure position in the in the Fig. 12 shown opening position moves, then the carriage 30 moves on the roller 35 in the direction of the support plate 2, wherein the push rod 37 - as mentioned above - entrained.

In this case, the lever 32 is fixed by the mounting profile 32 on the actuating rod 6, not shown here on the wing, since the actuating rod 6 is exclusively perpendicular to the wing plane displaced. The attachment of the fastening profile on the actuating rod is effected by the fixing plate 12 and 13. For this purpose, the fixing plate 12 engages in the Fig. 11 in a groove 43 of the mounting profile 23, if this is congruent with the insert body 11. By fastening screws, which pass through the holes 18 and have an abutment in the holes 16, that the fastening profile 23 along the groove 20 is fixed.

With this configuration, all components of the carriage 30 can be preassembled and coupled in a simple manner with the actuating rod 6. In addition, the lever arms 33, 34 engage around the fastening profile 23 in such a way that they are in the open position Fig. 12 are arranged laterally next to this. This reduces the space required for receiving the lever 32nd

According to the Fig. 4 It is provided that at each end of the retaining profile 14, a lever 32 is attached with a fastening profile 23. The respective carriages 30 are constructed essentially identically and connected via a connecting rod 44, which is only indicated here. For this purpose, the carriage 30 has on the slider 31 a coupling device 45 which is identical to the coupling device 36 (FIG. Fig. 10 ) is constructed. In both coupling devices 36, 44, a preassembled screw 46 is provided in a threaded bore of the slider or the coupling device 36. In this case, the connecting rod 44 is formed in its dimensions corresponding to the coupling approach 45 of the support plate 2, so that this would be selectively coupled to the coupling device 36 or the slider 31. As a result, the connecting rod 44 can be connected at one end to the slider 31 and the other end to the coupling device 36.

In synopsis of Fig. 13 and 14 It will be appreciated that the coupling lug 45 and the connecting rod 44 are so simple that they are equally suitable for coupling with the slider 31. The slider 31 has for receiving the connecting rod 44 has an opening 47 which is adapted to the shape of the connecting rod 44 so that it is fixed transversely to the longitudinal direction in each case form-fitting manner. On the support plate 3, a mounting lug 48 is attached to the one in the rear view Fig. 15 shown spring 49 can be coupled. The spring serves to return the lever 32 in the closed position. For this purpose, the spring 49 at the in the Fig. 4 right slide 30 attached. This is done via a coupling piece 50 that is inserted into the receptacle 51 of the coupling device 36 of the carriage 30. The carriage 30 is shown in the Fig. 15 designed essentially U-shaped. The free U-legs 52, 53 are provided with inwardly facing slugs 54, which form a guide for the coupling piece 50 and this set parallel to the U-legs 52, 53. A bore 55 in the coupling piece 50 serves to engage the fastening screw 46 (FIG. Fig. 10 ), so that the coupling piece 50 is formschlüsig fixed to the carriage 30.

On the coupling piece 50, a mounting lug 56 is attached, which corresponds to the attachment lug 48 substantially and serves to attack the spring 49 The above-described embodiment of the carriage 30 allows it to be produced as a stamped and bent part, so that in addition to a high load capacity and a cost-effective production is possible.

The provision of the lever 32 thus takes place exclusively via the single spring 49, which acts on the connecting rod 44 on both carriages 30. In this case, the spring 49 is attached via a spacer plate 56 to the support plate 3. The spacer plate 56 is provided with slugs 57 for positive engagement in holes in the support plate 3. Holes in the spacer plate 56 and the carrier plates 3 allow the spacer plate 56 is screwed together with the support plate 3.

In this case, the hole pattern and the position of the slugs 57 is identical to the spacer plate 39 of the support plate 2. In addition, the spacer plates 39, 56 formed symmetrically with respect to a horizontal transverse axis. As a result, the carrier plates and the spacer plates 39 and 56 can be used both for right and left hinged doors.

In the FIGS. 16 to 19 the construction and the arrangement of the caps 4, 5, 8 and 9 is shown. As already described above, the fixing plate 12, 13 is attached to the insert body 11 of the actuating rod 6, which is covered by the cover cap 9. The cap 9 engages around the cover 10 and has an opening 59 which is penetrated by the holding profile 14. From the Fig. 17 It is clear that under the caps 8 and 9, another cover 59 is located, which is provided with two perpendicular to the wing plane webs 60, 61, which are encompassed by the fixing plates 12, 13. In the in the Fig. 17 illustrated opening position these ridges 60, 61 almost to the limit of the grooves 62, 63 zoom in the fixing plate 12, 13 zoom. In this case, the cover 59 is approximately L-shaped and protrudes through an interruption 62 of the cap 5 under the edge therethrough. While the cover caps 8, 9 and the cover 8, 9 on both sides of the fitting set 1 identical and therefore can be used in both a left and right hinged wing, the covers 4 and 5 are different, as in a pivotable about a right axis wings the lock is attached to the left side. Accordingly, the spacer plate 39 with the push rod 37 must also be mounted on the left side of the wing. The opening 58 corresponding to the opening on the cap 4 for the passage of the cover 59 is the Fig. 19 Accordingly, therefore, to install on the left side of the cap 4. If the wing was struck on the left side, then a reverse arrangement is to be made. Therefore, that is in the Fig. 19 visible cover 63 is provided. This can either be coupled to the cap 4, 5 or is connected to this by a predetermined breaking point, so that it can be easily adapted depending on the location.

The assembly of the fitting 1 is therefore very simple. First, the support plates 2, 3 are mounted, whose position depends essentially on the position of the castle. The holding profile 14 and the operating rod 6 are adjusted in length by simple straight cuts. The connecting rod 44 is also adapted and connected to the carriages 30. The retaining profile is secured between the support plates 2, 3 and the carriages 30 can be mounted together with the connecting rod 44 and connected to the spacer plates 39, 56. The levers 32 can now be pivoted so far that the fastening profiles 23 can be inserted into the groove 20 of the insert body 11. This can also be done in confined spaces, since initially only one side must be introduced and sufficient space is created by further insertion in order to introduce the fastening profile 23 on the opposite side. Subsequently, the fastening profiles 23 can be fixed by means of the fixing plates 12, 13 ( Fig. 3 ).

The cover members 59 are then mounted in front of the cover members 8, 9. Finally, the caps 4, 5 are attached and gf. Still the cover 63rd
