Description

The present invention relates to a push rod device for actuating a door lock in a door. The door is preferably a panic door, ie a door in an escape and rescue route. The door has a door leaf movably mounted in a fixed door frame and the door lock is mounted in or on the door leaf,
full
a U-shaped basic profile (22) which can be fastened to the door leaf (16),
a manually operable U-shaped pressure profile (28), wherein the base profile (22) and the pressure profile (28) are inserted into each other via their respective open side and the pressure profile (28) is movable relative to the base profile (22),
a transmission system (30) disposed between the base profile (22) and the pressure profile (28) which converts movement of the pressure profile (28) into movement for actuating the door lock (18) by the transmission system (30) at one in the pressure profile (28) arranged receiving device (32) is coupled.

Panic doors should be understood in connection with the present application doors that are located in escape and rescue routes of buildings. Normally, the panic doors are closed, for example for sound insulation and insulation purposes. Panic doors can also be designed as fire protection closures. It is necessary to keep such panic doors closed to prevent the spread of a fire as long as possible. In the case of a dangerous situation, however, the panic doors have to be opened quickly and reliably in a simple manner. For this panic doors can be provided with push rod devices that extend in a horizontal arrangement on the door over a majority or even over the entire width of the door and thus provide a very easy way to panic case open the door lock and thus the panic door. To open the panic door, a user presses the pressure profile in the direction of the door leaf into the basic profile telescopically. The transmission system converts the movement of the pressure profile into a rotary movement with which the door lock connected via a connecting nut is opened.

To ensure the trouble-free operation of the push rod device, it is necessary to provide a reliable and reliable connection between the pressure profile and the transmission system or the receiving device of the transmission system. In conventional push rod devices, the relevant parts of the transmission system are clipped to the pressure profile, so that the pressure profile must have a connection point for providing the clip connection, to which the relevant part of the transmission system can be clipped. The junction is formed in known pressure profiles in the form of rails with undercut, which are arranged at the bottom of the pressure profile and over the entire Extend pressure profile. To provide the rails, the pressure profiles are usually extruded or extruded, but has the disadvantage that the choice of material for the pressure profiles is limited and the corresponding manufacturing processes are relatively expensive. Furthermore, in conventional push rod devices, the pressure profiles must have a certain material thickness, so that no metal sheets can be processed.

The DE 20 2009 009 609 U1 describes a push rod device in which the receiving device is attached to the bottom side of the pressure profile with a joint connection. In addition to the fact that the production of joint connections is relatively complicated compared to Klipsverbindungen, especially when using sheets with a low material thickness, the joints are also visible on the opposite side of the joint of the pressure profile. This page is the one that an observer is looking at, so that the push rod device produced in this way does not give an optically positive impression. To improve the visual impression, this page must be reworked, which is associated with costs and effort.

It should also include the case that the receiving device is indirectly or indirectly attached via the U-bracket device on the pressure profile, so has no direct contact with the pressure profile. In this case, the connection between the U-bracket device and the receiving device can be realized in any suitable manner. For this purpose, for example, a joint connection can be used, but in this case does not have to be arranged on the pressure profile and thus has no effect on the visual impression of the pressure profile. One-piece designs, preferably made of plastic, are possible. The U-bracket device is pressed with the Verspannmitteleinrichtung at their free ends against the projection means of the pressure profile, so that it is thus secured by a form and frictional engagement on the pressure profile.

The door hinges 14 are spaced along the vertical axis of rotation door to each other. The door leaf 16 is a stop swivel wing in the case shown. Embodiments of the door as a swing door, in which the door leaf 16 is designed as a swing door leaf, are basically also feasible with a corresponding design of the door hinges 14.

In the door leaf 16, a door lock 18 is arranged, which is typically designed as a mortise lock. On the door 16 is to operate the door lock, d. H. for unlocking by manual operation, a push rod device 20 attached, which extends almost over the entire width of the door leaf 16.

In the FIGS. 2a to 2c a first embodiment of the push rod device 20 according to the invention is shown in different views. The push rod device 20 comprises a U-shaped base profile 22, with which the push rod device 20 is attached to the door leaf 16. A U-shaped profile is to be understood as meaning a continuous profile having two side sections 24, a bottom section 26 arranged therebetween and an open side. The two side sections 24 include an angle with the bottom portion 26, which is typically about 90 °, the angle may also vary significantly from 90 ° depending on the purpose.

Further, the push rod device 20 includes a likewise U-shaped pressure profile 28, wherein the base profile 22 and the pressure profile 28 are inserted into each other via their respective open sides. In the example shown, the pressure profile 28 is introduced into the base profile 22 (see Figure 2c )), wherein it is also possible in principle that the pressure profile 28 overrides the base profile 22. The pressure profile 28 can be telescoped into the base profile 22. Between the base profile 22 and the pressure profile 28, a transmission system 30 is arranged, which converts the movement of the pressure profile 28 into the base profile 22 into a movement, with which the nut of the door lock 18 is rotated for unlocking and releasing the door leaf. In the example shown, the transmission system 30 comprises two spaced-apart receiving devices 32 arranged in a fixed manner in the pressure profile 28, with which the movement of the pressure profile 28 is received and forwarded accordingly to the transmission system 30. The pressure profile 28 is guided via a linear guide 34 relative to the base profile 22 movable. The linear guide 34 comprises per receiving device 32, a guide portion 36, which is respectively attached to the receiving device 32, and a guide portion of the respective receiving device 32 associated guide rail 38 which is fixed to the base profile 22, perpendicular to the bottom portion 26 of the base profile , Upon actuation of the push rod by pushing the pressure profile 28, the guide portions 36 of the receiving means 32 linearly run on the associated guide rail 38. The linear guide 34 defines the direction of movement of the pressure profile 28 relative to the base profile 22.

On each of the guide rails 38, a respective two-armed transmission lever 40 belonging to the transmission system 30 is furthermore rotatably mounted, wherein a first arm 42 is guided in a coupling device 39 of the receiving device 32. The coupling device is designed in the illustrated case as a cam slot 41 in the receiving device 32, in which engages the free end of the arm 42 of the gear lever 40 guided. The second arm 44 of the gear lever 40 engages in an opening or recess 46 of a along the bottom portion 26 of the pressure profile 28 extending axially movable coupling rod 48 a. The coupling rod 48 is connected at its door lock end with a rocker arm 50 which engages in a crank arm 52, not shown in detail of a base profile 22 rotatably mounted nut 54. The nut 54 is rotatably connected via a driving pin with the aligned locknut of the mortise lock 18.

If the pressure profile 28 is pressed by a user into the base profile 22, the guide portion 36 is moved along the guide rail 38. In this case, the arm 42 of the lever 40 is displaced within the link slot 41, whereby the lever 40 performs a rotational movement, which is transmitted from the other lever arm 44 of the gear lever 40 to the coupling rod 48. The coupling rod 48 performs an axial movement, which is converted by the rocker arm 50 and the crank arm 52 in a rotational movement of the nut 54 and consequently the non-rotatably connected lock nut of the mortise lock is rotated in the unlocking direction.

The receiving devices 32 are used to record and transmit the movement of the pressure profile 28 on the transmission system 30 of Ram means. It must therefore be ensured that the receiving devices 32 are reliably and permanently connected to the pressure profile 28.

In the first embodiment, in the FIGS. 2 to 5 is shown, for this purpose, a U-bracket device 55 is provided with a U-bracket 56 which is inserted into the pressure profile 28 and with its two free ends against a respective projection means 58 on the two side portions 24 of the pressure profile 28 rests.

The receiving device 32 comprises a body (s. FIG. 5 ), which is also U-shaped in cross section. It consists essentially of a base plate 63 and two perpendicular thereto side walls 65. The side walls 65 have a slotted slot 41, which serves as the already mentioned coupling device 39 for the transmission system 30. The link slot extends substantially parallel to the base plate 63. The also already mentioned guide section 36 is also formed in the two side walls 65. The two side walls are for this purpose formed in opposite position to the outside, so that the herein complementary engaging guide rails 38 of the base profile 22 are guided perpendicular to the base plate 63 of the receiving device 32. Furthermore, the receiving device 32 has a plate-shaped foot portion 62 which engages between the U-bracket 56 and the bottom portion 26 of the pressure profile 28. This foot portion 62 has recesses 64, in which corresponding fixing projections 66 of the U-bracket 56 engage. The Fixiervorsprünge 66 are formed on the bottom bracket 56 on the bottom. Within the Fixiervorsprünge 66 are threaded holes 67th provided with internal thread (s. Figure 2c ), in which screws of a Schraubenverspanneinrichtung 68 are screwed so that they are supported with tightened screws on the foot portion 62 of the receiving device 32. By tightened screws of Schraubenverspanneinrichtung 68 of the foot portion 62 is pressed against the bottom portion of the pressure profile 28 and at the same time the U-bracket 56 moves away from the foot portion 62 and the bottom portion of the pressure profile 28, so that the free ends of the U-bracket 56 against the projection means 58 are strained. The screws of the Schraubenverspanneinrichtung 68 are tightened so far that the U-bracket 56 presses the receiving device 32 so strongly against the pressure profile 28 that it is securely connected to the pressure profile 28 due to the then acting in the bias friction. In this respect, the screws of the Schraubenverspanneinrichtung 68 as Verspannmittel the Verspannmitteleinrichtung 70. The foot portion 62, which is pressed by the screws of Schraubenverspanneinrichtung 68 to the bottom of the pressure profile, provides a pressure transmission device between the screws of Schraubenverspanneinrichtung 68 and the bottom of the pressure profile 28.

In the single part representation in FIG. 5 the receiving unit is shown in a perspective view. It can be seen the depressions 64, in which the fixing projections 66 of the U-bracket 56 can engage. Furthermore, the guide portion 36 can be seen, the guide rail 38 of the base plate (see. FIGS. 2a to 2c ), whereby the linear guide 34 of the pressure profile 28 is provided. Furthermore, the sliding recess 41 can be seen, via which the movement of the pressure profile 28 is transmitted to the gear lever 40.

In FIG. 6 a second embodiment of the unlocking device 20 according to the invention is shown, wherein only the relevant parts for the present invention are shown here. In this embodiment, the receiving device 32 has no foot portion 62 which is disposed between the bottom portion 26 of the pressure profile 28 and the bottom of the U-bracket 56. The U-bracket 56 and the pressure profile 28 are not changed compared to the first embodiment. In this embodiment in FIG. 6 the receiving device 32 has a connecting portion, via which the receiving device 32 is attached in a manner not shown on the U-bracket 56, for example, with a joining, gluing or screw connection. Again, the U-bracket 56, the threads 67, in which the screws of the Schraubenverspanneinrichtung 68 are screwed. In contrast to the first embodiment, the screws of the screw tensioning device 68 are not supported on a foot section 62 of the receiving device 32, but directly on the bottom 26 of the pressure profile 28 in this second embodiment. As a result, the U-bracket 56 is urged in the direction of the projections 58 and thus clamped to the pressure profile 28. As already mentioned, the receiving device 32 is attached directly to the U-bracket 56 in this embodiment. In this Embodiment in FIG. 6 the receiving device 32 is not attached directly to the pressure profile 28 by the bracing. It is not in direct contact with the pressure profile 28. Rather, the receiving device 32 is fixed in a manner not shown with the U-bracket 56 and is indirectly attached via the U-bracket 56 to the pressure profile 28. There are also designs of in FIG. 6 illustrated example conceivable in which the body of the receiving device 32 is integrally connected to the U-bracket 56.
