Fig. 1 shows a pneumatically actuated door opener 1, which has a door opener housing 11. The door opener housing 11 is formed substantially cuboid and has a removable cover 12. The pneumatically actuated door opener 1 can be installed in a fixed frame of a door or a grand piano. It can be installed in particular in a castle counter box or connected to a strike plate. For this purpose, the door opener housing 11 on its front side two mounting holes 13a and 13b. These are in the representation of FIG. 1 arranged left and right of a door opener housing 14 pivotally mounted in the door opener housing 11.

At a lateral end of the door opener housing 11, a pneumatic connection device 5 is attached. The Pneumatic connection device 5 has an outer connection 51, to which a compressed air line can be connected.

In the Fig. 2a and 2 B the pneumatically actuated door opener is shown in a design as rest air door opener, which has a trained as a working cylinder pneumatic cylinder.

Fig. 2a shows the pneumatically actuated door opener 1 with the cover removed.

The door opener housing 11 encloses an approximately cuboid space in which the components of the door opener 1 are accommodated. A door opener anchor or anchor 21a is pivotally mounted in the door opener housing 11 via a pivot bearing 23. The door opener anchor 21a cooperates with a change 24 for blocking or releasing a pivoting movement of the door opener latch 14. The door opener change 24 is connected between the door opener anchor 21 a and the door opener latch 14 and pivotally mounted about a pivot bearing 25 in the door opener housing 11. The pivot axis of the pivot bearing 23 and the pivot bearing 25 are parallel to each other.

The door opener housing 11 has a further pivot bearing, which door lock latch 14 pivotally supports. The door opener latch 14 is pivotally mounted in the door opener housing 11 about a pivot axis 15 shown in dashed lines. The pivot axis 15 of the door opener latch 14 extends parallel to the longitudinal axis of the door opener housing 11 and perpendicular to the two parallel pivot axes of the door opener anchor 21 a and the change 24th

In Fig. 2b is the interaction of the blocking device 2 between the change 24 and the door opener 21 a shown in more detail. The armature 21 a is arranged together with the change 24 in a first plane. A designed as a working air cylinder pneumatic cylinder 4, which extends substantially parallel to the pivot axis 15 of the door latch 14 is disposed in a second plane which is parallel and spaced from the first plane of the armature 21 a and 24 of the change. In the presentation of the Fig. 2b The first level is located above the second level.

The pneumatic cylinder 4 has a cylinder housing 42 in which a piston rod 41 is slidably mounted. Via a pneumatic hose 43, the pneumatic cylinder 4 is connected to an internal air connection 52 of the pneumatic connection device 5. The pneumatic connection device 5 has an intermediate piece 53 which supports the inner air connection 52 and the outer air connection 51. The pneumatic intermediate piece 53 is held in the door opener housing 11 via a tongue and groove connection. At the outside air connection 51, a compressed air line is connected during the installation of the door opener 1, via which the pneumatic cylinder 4 can be acted upon with compressed air.

The pneumatic cylinder 4 is designed as a working air cylinder, d. H. When the pneumatic cylinder 4 is pressurized with compressed air, the piston rod 41 extends out of the housing 42 of the pneumatic cylinder 4. For holding the pneumatic cylinder 4, the door opener housing 11 has a holder 16 which engages around the housing of the pneumatic cylinder 42 in a form-fitting manner.

The piston rod 41 of the pneumatic cylinder 4 acts on a transmission element 3a, which is designed as a roller and a central bearing journal 33a has, which is received in a arranged on the door opener housing 11 bearing. The bearing pin 33a simultaneously serves as a pivot axis for the transmission element 3a. The transmission element 3a has a receptacle 31 a, which cooperates directly with the piston rod 41 by the piston rod 41 engages in the recess 31 a. The recess 31 a is arranged eccentrically on the transmission element 3 a, so that this is rotated when the piston rod moves out of the cylinder housing 42.

The transmission element 3a is disposed below the door opener anchor or armature 21a and has a web 32a. As in Fig. 2a can be seen, the web 32a extending from the gear element 3a upwards into the range of movement of the armature 21 a into it. The web 32a is located on the outside of the armature 21 a. When pressurized air presses the transmission element 3a via the web 32a the door opener 21 a against the spring force of the armature spring 22 a inwardly into the in the Fig. 2a illustrated locking position.

In the in Fig. 2a shown locked or locked position, the change 24 engages behind a groove of the armature 21 a and is thus locked against pivoting. At the same time, the change 24 is directly adjacent to a projection of the door opener catch 14 and thus prevents it from being pivoted about its pivot axis 15. That means in the in Fig. 2a shown position, the door opener 14 of the pneumatically actuated door opener 1 is locked. It is thus a rest air door opener, which is locked as soon as it is pressurized with compressed air. If the compressed air is switched off, the armature spring 22a pushes the armature 21a out of engagement with the change 24. The change 24 can then be pivoted about its bearing 25 again and releases the door opener latch 14. About the spring 22 a, the armature 21 a acts on the Transmission element 3a on the piston rod 41 of the pneumatic cylinder 4 and pushes the piston rod 41 back into the Zylindergehäue 42 of the pneumatic cylinder 4th

To keep the door opener latch 14 in unlocked door opener in the neutral position, two are formed as compression springs changeover springs 26 connected in parallel, which act between door opener housing and 24 change. They fix over the change 24, the door opener 14 in the neutral position, but are überdrückbar with relatively little effort.

The Fig. 3a and 3b show the pneumatically actuated door opener 1 in an embodiment as Arbeitslufttüröffner. He is constructed largely identical, as in the FIGS. 2a and 2 B shown embodiment, which comes, inter alia, by the same reference numerals in identical components. The different features will be described in detail below. The door opener 1 has as in the FIGS. 2a and 2 B shown embodiment designed as a working air cylinder pneumatic cylinder 4.

In the Fig. 3a is the pneumatically actuated door opener 1 again shown with removed door opener cover. To illustrate the inner life of the change 24 is removed. As already at the in the Fig. 2a and 2 B variant described, the door opener housing 11 has a roughly cuboid space in which the components of the door opener are added. The door opener latch 14 is pivotally mounted in the door opener housing about a pivot axis 15 extending along the longitudinal extent of the door opener housing 11. Parallel to this pivot axis 15 extending a pneumatic cylinder 4 is mounted in a bearing block 16 of the door opener housing 11. The pneumatic cylinder 4 has a Cylinder housing 42 with one of the cylinder housing 42 at druckausfahrender piston rod 41.

Via a pneumatic hose 43, the pneumatic cylinder 4 is connected to the inner connection 52 of the pneumatic connection device 5. The pneumatic connection device 5 again has an intermediate piece 53, which is held in the door opener housing 11 via a tongue and groove connection. A pneumatic outer terminal 51 is provided to connect the door opener 11 with a compressed air line to supply the door opener 1 and the pneumatic cylinder 4 with compressed air. A blocking device 2 is provided to block or release the movement of the door opener latch 14. The blocking device 2 comprises a door opener anchor or anchor of the first type 21 b and a cooperating with this anchor change 24. The armature 21 b is in turn supported in the Türöffergehäuse 11 via the bearing 23 pivotally. Also, the change 24 is pivotally mounted in the door opener housing as in the previous embodiment about a pivot bearing 25.

Unlike in the Fig. 2a and 2 B illustrated embodiment, no gear member is now included in the door opener housing 11, but the piston rod 41 of the pneumatic cylinder 4 acts directly with the armature 21 b together. The door opener anchor 21 b differs from the armature 21 a. The anchor of the second type 21 a is flat and extends only in the first plane, as in the FIGS. 2a and 2 B is shown. The armature of the first type 21 b has a nose 3b, which projects from the armature 21 b down into the range of movement of the piston rod 41. It thus extends from the first plane to the second plane in which the pneumatic cylinder 4 is arranged.

The piston rod 41 acts on the nose 3b for pivoting the armature 21 b directly. When pivoting of the armature 21 b by the pneumatic cylinder 4 and the piston rod 41, an armature spring 22 b is charged, the armature 21 b and the piston rod 41 against the pneumatic cylinder acted upon when depressurizing the pneumatic cylinder so that the armature 21 b, the change 24 engages behind and this locks. That means that in the Fig. 3a and 3b shown pneumatically actuated door opener 1 is locked without pressurization, or that the door opener trap 14 is locked without pressurization and thus is a Arbeitslufttüröffner. The change 24 is in turn acted upon by means of two alternating springs 26 in order to keep the door opener latch 14 in a neutral position.

The in the Fig. 2a and 2 B Resting air door opener shown is simply in the in the Fig. 3a and 3b shown Arbeitslufttüröffner convertible. All you need to do is to place the anchor of the first type in the Fig. 2a and 2 B designated by the reference numeral 21 a, against the anchor of the second type, in the Fig. 3a and 3b designated by the reference numeral 21 b, are exchanged. Next, the transmission element 3 a must be removed from the door opener housing 11. Likewise, the point of application of the armature spring 22a, in the Fig. 2a and 2 B between the armature 21 a and the storage box 16 is changed to the effect that the spring 22 b in the Fig. 3a and 3b between the wall of the door opener housing 11 and the armature 21 b is arranged. Alternatively, for example, the spring 22a could be exchanged by a compression spring in a tension spring to achieve the same effect.

Thus, the pneumatically actuated door opener 1 can be produced as Ruhelufttüröffner or Arbeitslufttüröffner with a few simple steps. In particular, no component of the pneumatic system has to be changed or arranged differently during the conversion. The conversion is limited to the replacement of simple mechanical parts. Thus, it is possible to use a maximum number of identical components to produce the pneumatically operated door opener 1 in a variant as Restelufttüröffner and in another variant as Arbeitslufttüröffner.
