Thus, by the term that the triggering device serves to open the housing at and / or above a triggering temperature, it is to be understood that the housing can be opened by the triggering device at and / or above a triggering temperature.

At and / or above the triggering temperature, in particular at the triggering temperature, the volume of the triggering material can increase suddenly. In particular, the volume of the triggering material can increase by more than 20%, preferably more than 50%, particularly preferably more than more than 100%. It is even conceivable that the volume of the triggering material increases by at least 3 times, preferably by at least 5 times, more preferably by at least 7 times.

In particular, the housing may comprise a diaphragm. The aperture can be at least partially detached from the rest of the housing by the increase in volume, so that the housing is opened. The panel can be arranged opposite the back. Thus, the aperture may at least partially form the front of the housing.

Due to the increase in volume of the triggering element, in particular at most a part of the housing is moved.

It is preferably provided that the triggering material is formed as an intumescent material. The triggering temperature can correspond to the intumescent temperature. Additionally or alternatively, the trigger material can absorb heat to increase the volume.

A maximum operating temperature of the electrochemical energy store may be above the triggering temperature.

The holder can be arranged below the release temperature in the housing. The electrochemical energy store can be arranged below the release temperature in the housing.

Due to the increase in volume of the triggering device, the holder can be moved away from a rear side of the housing. As a result, the electrochemical energy store can be moved away from the rear side. Thus, it may be that the triggering device can remove an obstacle by the increase in volume that prevents below the triggering temperature, a movement of the holder. Additionally or Alternatively, it may be that the triggering device causes the movement or contributes to the movement.

Due to the increase in volume of the triggering device, the holder can be at least partially moved out of the housing. As a result, the electrochemical energy store is movable out of the housing. Thus, it may be that the triggering device can eliminate an obstacle by the increase in volume that prevents below the triggering temperature, a movement of the holder out of the housing. Additionally or alternatively, the triggering device may cause the movement or contribute to the movement.

In particular, the at least one electrochemical energy store is moved together with the holder. Thus, the electrochemical energy storage is moved away from a building door or a wall and / or moved out of the housing. As a result, a move away from the heat source takes place. Heating of the electrochemical energy store is delayed. Through the opening of the housing of the electrochemical energy storage is cooled.

The holder may in particular be formed of poorly heat-conducting material with a thermal conductivity of less than 3 W / (mK), preferably less than 1W / (mK). In particular, the holder may be formed as a plastic.

It is preferably provided that the triggering device moves the holder through the increase in volume. Preferably, it is therefore provided that the triggering device not only eliminates an obstacle, but itself causes the housing opening. Preferably, the triggering device at least partially displaces the holder. In this case, the triggering device can also cause a pivoting of the holder.

The triggering device can at least indirectly move the shutter. In particular, it is provided that the triggering device moves at most a part of a housing of the door device by the increase in volume. For example, the back, in particular the mounting plate, remains on the wall or on the door.

It may be that the triggering device is located between the holder and the back of the housing. The triggering device can thus move away from the rear of the housing by the increase in volume, the holder. The holder can be arranged between the triggering device and the electrochemical energy store.

In particular, the holder may comprise a rear wall. The rear wall of the holder may face the rear of the housing. Preferably, the rear wall of the Holder arranged between the triggering device and the electrochemical energy storage.

The triggering device can rest on the holder, in particular on the rear wall.

The triggering device and the holder can be connected to each other. The triggering device may at least partially remain in the housing at and in particular above the triggering temperature. Due to the connection of the triggering device and the holder, the holder can be prevented from falling out of the rest of the door device when the holder is moved out of the housing. In particular, the triggering device and the holder can be integrally connected to one another, in particular adhesively bonded.

It may be that the holder comprises at least one side wall. The side wall may be facing a ceiling in the assembled state of the door device. Thus, the side wall may be formed as an upper side wall. Alternatively or additionally, a side wall in the assembled state of the door device may be facing a room floor. Thus, the side wall may be formed as a lower side wall. Preferably, the holder comprises at least two side walls, in particular the upper and the lower side wall.

The lower side wall can be provided so that the lower side wall is in the assembled state of the door device after moving out of the housing between the electrochemical energy storage and a room floor. Thus, the lower side wall can serve as a heat shield at the same time. The lower sidewall can bypass warm air at the overlying electrochemical energy store. As a result, heating of the electrochemical energy store may be delayed.

The holder may be guided during a movement of the holder, which was caused by the increase in volume of the triggering device. The sidewall may serve to guide the mount during movement of the mount caused by the volume increase of the trip device. The side wall may rest against the housing at least indirectly during the movement of the holder. By the concern of the side wall to the housing, the holder may be guided during the movement. Preferably, the upper and lower side walls may guide the support during movement of the support caused by the increase in volume of the release device.

Below the release temperature, the side wall or the side walls are preferably spaced from the housing.

It can be provided that the holder comprises at least one spacer element. The spacing element may serve to space the remainder of the support from at least one side of the housing. This reduces heat transfer from the housing to the holder. The housing side may be a housing side, which faces the room floor in the mounted state of the door device. Thus, it may be a lower side of the housing. The housing side can be a housing side, which faces the ceiling in the installed state of the door device. Thus, it may be an upper side of the housing. Preferably, the spacer protrudes from the side wall. The side wall may in particular be the upper or lower side wall.

The holder preferably comprises a plurality of spacing elements. It is conceivable that a plurality of spacing elements are arranged on a side wall. Alternatively or additionally, the spacing elements may be arranged on a plurality of side walls. Particularly preferably, the spacing elements are arranged on the upper and on the lower side wall.

Particularly preferably, the at least one spacing element is located on a half of the side wall remote from the rear side. Thus, the spacer element is located in a front portion of the side wall. The spacer elements may be located at the front portion of the side wall (s). As a result, heat transfer to the holder is difficult.

The spacer element or elements projecting from a sidewall may occupy less than 20%, preferably less than 10%, more preferably less than 5% of a sidewall surface in a plan view of the sidewall. As a result, the holder can rest only to a small extent on the housing, so that a heat transfer is difficult.

It is conceivable that the holder comprises a retaining element. The retention member may be for retaining a portion of the support in the housing during the increase in volume. Thus, it may be that only a part of the holder moves out of the housing at and / or above the triggering temperature. In particular, the retaining element can serve as a pivot axis.

It may be that a gap between the retaining element and the back of the housing is formed free of the triggering device. As a result, a movement of the retaining element is reduced or prevented by triggering element.

The rear wall comprises a first area, in particular an end area. The triggering device is not located between the first area and the back of the housing. In other words, the first area of the rear wall projects beyond the triggering device in a plan view. It is preferably provided that the first region is located between the retaining element and the rear side.

It is conceivable that the retaining element corresponds to the spacing element or at least one of the spacing elements.

The holder may comprise a fastening element for fastening a panel. The holder may include a support surface for the panel. The support surface may be formed by the side walls. It can be provided that the support surface is interrupted by at least one indentation. As a result, a ventilation and thus a heat accumulation is prevented when the panel moves together with the holder from the housing. As an alternative to the at least one indentation, the holder may comprise openings for this purpose.

Additionally or alternatively, the door device may comprise a fastening device for fastening the panel, wherein the holder and the fastening device are formed separately from each other. The fastening device is provided in particular outside the holder.

The panel may be attached to the fastening element and / or the fastening device such that the panel is movable in at least one spatial direction. In particular, the spatial direction may be a spatial direction deviating from the direction of movement of the holder. In particular, the spatial direction in which the diaphragm can move, are perpendicular to the spatial direction of movement of the holder. In particular, the diaphragm can move parallel to the rear side of the housing.

The diaphragm may preferably be magnetically fixed to the fastening element and / or the fastening device.

The diaphragm is preferably so flexible that the diaphragm deforms during the movement of the holder. The panel can be made of plastic. As a result, a heat transfer from the diaphragm is reduced to the holder.

The holder can assume a first position below the release temperature. The holder may be held by form and / or adhesion means in the first position. The form and / or adhesion means go to this a form and / or adhesion. By means of the positive and / or positive locking means, a movement out of the housing can be prevented, in particular below the triggering temperature.

It is conceivable that due to the increase in volume of the triggering element, a form and / or frictional connection with which the holder is held in the first position is canceled. Due to the fact that the triggering element releases the positive and / or non-positive connection, a well-defined cancellation of the positive and / or non-positive connection is possible.

It is conceivable that at least one of the positive and / or positive locking means deforms at and / or above the triggering temperature due to the increase in volume of the triggering element. Additionally or alternatively, the at least one positive and / or frictional means may break at and / or above the triggering temperature due to the increase in volume of the triggering element. The holder may comprise the form and / or adhesion means.

It may alternatively be that the positive and / or frictional means is moved away by the increase in volume of the triggering element from a first position, so that the positive and / or positive connection is repealed. The positive and / or frictional means may be in the first position in a positive and / or frictional connection with the holder. The form and / or adhesion can be reversibly solved by the increase in volume of the trigger element.

The positive and / or positive locking means can be moved directly or indirectly by the triggering element from the first position. In an indirect movement of the positive and / or non-positive means by the triggering element, in particular, a deflection device between the triggering element and the positive and / or positive-locking means may be provided. The deflection can z. B. be designed as a lever. Due to the deflecting device, the spatial direction in which the trigger element moves during the increase in volume can differ from the spatial direction in which the positive and / or positive locking means moves in order to release the positive and / or positive connection.

The positive and / or positive locking means can be acted upon by a spring in the direction of the first position.

If the triggering element serves to move the positive and / or positive locking means away from the first position, then the triggering element can be arranged closer to the back than the holder. As a result, in particular, the triggering element heats up in front of the holder so that the positive and / or non-positive connection is released before the holder is moved out of the housing and / or the electrochemical energy stores become too hot.

The holder may have a contact surface for abutment with a housing side, which is opposite to the rear side and / or in the direction of movement of the holder in the Volume increase is included. Thus, the contact surface can serve as a form and / or adhesion means. In particular, the spacer element may comprise the contact surface. It is conceivable that the contact surface breaks off at a volume increase of the triggering element of the rest of the holder. Additionally or alternatively, the contact surface may deform.

It is conceivable that the holder comprises a plurality of contact surfaces. The contact surfaces can serve as a form and / or adhesion means.

The door device may comprise a tensioning means. The holder can be clamped by means of the tensioning means within the housing. It is conceivable that the holder is received in a rail. The housing may comprise the rail. The bracing means can brace the bracket in the rail. By means of the tensioning means, the holder can be prevented from moving below the triggering temperature. For example, the holder can rest against the housing with the contact surface. The tensioning means ensures that the contact surface is pressed against the housing. The tensioning means may be elastic. Alternatively or additionally, the tensioning means may be variably fixed in the holder. For example, when inserting the holder into the housing, in particular into the rail, the bracing means may protrude slightly or not at all out of the holder. In the inserted state, the tensioning means is at least partially moved out of the holder, whereby the holder in the housing, in particular in the rail, is braced. For example, the tensioning means may be formed as a screw which can be screwed for clamping. The door device may comprise a plurality of tensioning means.

It may be that the rear wall of the holder is spaced apart from a member located behind the rear wall by a spacing means. The element can lie between the back and the holder. The element adjoins the holder. For example, the element may correspond to an intermediate wall of the housing. The element can be part of the rail.

In particular, the spacing means may correspond to the tensioning means. The spacing means may be formed as a screw. In particular, the spacer means is located at a point on the element located behind the rear wall.

There may be provided a plurality of spacing means. A bearing surface of the spacing means or the spacing means on the element may correspond to less than 10%, preferably less than 5%, particularly preferably less than 2% of the area of the rear wall.

The holder can be designed in several parts. This makes it possible to pivot the parts of the holder by the increase in volume in particular against each other.

The door device may comprise a plurality of electrochemical energy stores. Each part of the holder can accommodate at least one electrochemical energy storage.

The door device may comprise at least two storage groups, each storage group comprising at least one of the electrochemical energy stores and a binding element for the at least one electrochemical energy store. Each part of the holder can accommodate at least one storage group.

It is preferably provided that the electrochemical energy store is connected to the holder only via the electrical contacting of the energy store. As a result, the heat transfer is reduced to the electrochemical energy storage.

Additionally or alternatively, the electrochemical energy store may be spaced from at least one sidewall, preferably from the sidewalls. As a result, the heat transfer is reduced to the electrochemical energy storage. For this purpose, the binding elements can be dimensioned in such a way that the binding elements space the electrochemical energy stores from the side wall or from the side walls.

FIG. 1 shows a door device 1 according to the invention in an exploded view. The Türrvorrichtung 1 is exemplified as a locking device 1 is formed. The locking device 1 serves to determine a not shown building door in a detected state of the locking device 1. In a releasing state of the locking device 1, however, a movement of the building door is released. In particular, the locking device is adapted to hold the building door in an open state and to release a closing of the building door in case of fire. Thus, the locking device is suitable for detecting a fire door.

The locking device 1 comprises a slider 2. The slider 2 can be locked and unlocked by a locking mechanism 3. The slider 2 is guided in a slide rail 4. The slider 2 is connected via a lever, not shown, with the building door, in particular with the fire door, connectable. A control device 5 receives a signal from a fire detector and then causes the locking mechanism 3 to release the slider 2.

The door device 1 comprises a housing 10. The housing 10 encloses the control device 5. The housing 10 accommodates the slide rail 4.

The housing 10 includes a back 11 which serves for attachment to the building door, in particular a door frame, or a wall. The back 11 includes a mounting plate 12. The back 11 may comprise a layer of intumescent material facing the wall or the building door. The layer of intumescent material may be attached to the mounting plate 12.

The housing 10 comprises a diaphragm 13. The diaphragm 13 is arranged opposite the rear 11. Thus, the aperture 13 at least partially forms a front side of the housing 10.

The housing 10 includes an upper housing side 15. The upper housing side 15 faces in a mounted state of the door device 1 a ceiling. The housing 10 includes a lower housing side 16. The lower housing side 16 faces in a mounted state of the door device 1 a room floor.

The housing 10 may include an H-beam 14. The H-beam 14 may form the upper housing side 15 and the lower housing side 16. An intermediate wall 18 of the H-beam connects the upper side of the housing 15 with the lower side of the housing 16. By the Partition 18, the housing 10, a first receiving space 6 and a second receiving space 7 available, as in FIG. 4 shown.

The second receiving space 7 is formed as a rail. For this purpose, the upper housing side 15 and the lower housing side 16 each have a projection 19 (s. FIG. 4 ).

The housing may include side elements 17.

The door device 1 comprises electrochemical energy stores 21. The electrochemical energy stores 21 are used to supply the door device 1, in particular the control device 5 and / or the locking mechanism 3, with electric current. In this case, in particular, the supply of electric current can be effected exclusively by the electrochemical energy store 21. The electrochemical energy storage 21 are designed as a battery or accumulator. The electrochemical energy storage 21 are accommodated in a holder 20. The holder 20 with the electrochemical energy stores 21 is accommodated below a release temperature in the housing 10.

The door device 1 comprises a triggering device 30, which in FIG. 2 is shown. The triggering device 30 serves to open the housing 10 at the triggering temperature. Through the opening of the housing 10, excessive heating of the electrochemical energy store 21 can be prevented. As a result, the safety of the door device 1 can be ensured even at the release temperature. The triggering device 30 is formed of intumescent material. At the release temperature, the volume of the triggering device 30 increases abruptly, in particular by a multiple. The increase in volume can be continued above the triggering temperature. The increase in volume of the intumescent material can be caused by evaporation, in particular of water. Characterized in that the triggering device 30 is made of intumescent material, the housing 10 is opened particularly reliable.

The triggering device 30 opens the housing 10 by the aperture 13 is moved according to the direction of movement 100 of the remaining housing. The triggering device 30 opens the housing 10 by the triggering device 30 moves the holder 20 in the direction of movement 100, in particular displaces or pivots. The holder 20 in turn moves the aperture 13th

The triggering device 30 moves the holder 20 with the electrochemical energy stores 21 by the increase in volume at least partially out of the housing 10 according to the direction of movement 100 out. A movement out of the housing 10 is understood to mean a movement out of a gap between the upper housing side 15 and the lower housing side 16. In particular, the holder moves with the electrochemical energy storage 21 out of the second receiving space 7 out. As a result, a strong heating of the electrochemical energy store 21 can be prevented particularly well. The holder 20 with the electrical energy storage 21 is located after the increase in volume of the trigger element 30 partially outside the space between the upper side of the housing 15 and lower side of the housing 16. The aperture 13 may remain attached to the holder 20.

The triggering device 30 is arranged between the holder 20 and the back 11. The triggering device 30 abuts against the holder 20. Preferably, the triggering device 30 is connected to the holder 20, in particular glued. As a result, the holder 20 is kept out of the housing 10 during a partial movement of the holder 20. Thus, a drop of the holder 20 is prevented.

The triggering device 30 may be plate-like. The holder 20 has a rear wall 22. The rear wall 22 faces the rear side 11 of the housing 10. The triggering device 30 can rest on the rear wall 22, in particular being connected to the rear wall 22. In FIG. 2 The tripping device 30 covers the rear wall 22 with the exception of end regions 23 of the holder 20. The end regions 23 are web-shaped in the region of the rear wall 22. As a result, the heat input via the end regions 23 is low.

The holder 20 comprises elements 24. The elements 24 may at least partially serve as retaining elements 241. The retaining elements 241 serve to partially retain the holder 20 in the housing 10 when the volume of the triggering element 30 increases in volume. Here, the retaining elements 241 serve as a pivot axis. As a result, the holder 20 can be prevented from falling down. The retaining elements 241 serving as a pivot axis are preferably arranged in the region of the end regions 23. Thus, the retaining elements 241 serving as the pivot axis are located obliquely next to the triggering device 30. A space between the retaining elements 241 and the mounting plate 12 is free of the triggering device 30.

The bracket 20 includes side walls 25, 26, in particular an upper side wall 25 and a lower side wall 26 (see FIG. FIG. 3 ).

The lower side wall 26 serves to be located after the increase in volume of the trigger element 30 outside of the housing 10 between the electrochemical energy storage 21 and the room floor. As a result, heat can be prevented from the electrochemical energy storage 21.

The side walls 25, 26 can serve to guide the holder 20 during the movement of the holder 20 during the increase in volume of the trigger element 30.

Below the triggering temperature, the side walls 25, 26 spaced from the upper or lower housing side 15, 16. Serve the elements 24, the spacer elements 24 correspond. The spacer elements 24 object to the side walls 25, 26 from the upper or lower housing side 15, 16. For this purpose, the spacing elements 24 protrude from the side walls 25, 26. The spacing elements 24 are arranged in a half of the side walls 25, 26 remote from the rear 11.

In the space between the side walls 25, 26 and the upper and lower housing side 15, 16 cooling elements 31 are arranged. The cooling elements 31 are formed of intumescent material. The cooling elements 31 protect the electrochemical energy store 21 from being heated by the cooling elements 31 effecting cooling above the intumescence temperature.

The holder 20 is below the release temperature within the housing 20, in particular within the second receiving space 7, attached. The holder 20 includes contact surfaces 27. The contact surfaces 27 abut against the projections 19. The elements 24 comprise the contact surfaces 27.

The holder 20 is clamped in the housing 10. For this purpose, the door device 1 comprises an unillustrated tensioning means. The tensioning agent is z. B. formed as one or more screw. The tensioning means is fixed in the holder 20. The tensioning means is preferably fixed in the rear wall 22, in particular in the end regions 23. For this purpose, the end regions 23 can comprise tensioning means receptacles 28 (see FIG. FIG. 2 ).

The tensioning means, in particular a tip of the screw, bears against the intermediate wall 18. Thus, by the tensioning means and the contact surfaces 27, the holder 20 in the housing 10, in particular in the second receiving space 7, braced.

The tensioning means spaces the holder 20 from the intermediate wall 18. This reduces the heat input into the holder 20. Thus, the tensioning means also serves as a spacing means.

Due to the positive connection of the contact surfaces 23 with the projections 19, the holder 20 is held in the direction of movement 100 positively below the release temperature. The contact surfaces 23 and the projections 19 thus serve as positive locking means. With an increase in volume, the positive connection of the contact surfaces 23 with the projections 19 is at least partially canceled. Due to the increase in volume breaks at least a portion of the elements 24 and thus the contact surfaces 23 from the rest of the holder 20 from.

In particular, the elements 24, which are arranged in the direction of movement 100 in front of the triggering device 30 and are provided with the reference numeral 242 in the figures, break off. Thus, the elements 24, which are not arranged in front of the end regions 23, break off.

Therefore, the elements 24 partially serve as retaining means 241, while a further part 242 of the elements 24 by canceling the suspension of the positive connection and the opening of the housing 10 allow. All elements 24 serve as a spacing element and all elements 24 comprise contact surfaces 23 as positive locking means.

The holder 20 comprises fastening elements 29 for fastening the panel 13. The panel 13 is magnetically fastened to the fastening elements 29. The holder 20 is further designed such that the aperture 13 rests on the holder 20.

The door device 1 comprises fastening devices 9 to which the panel 13 is fastened. The fastening devices 9 are arranged outside the holder 20. The diaphragm 13 is magnetically fixed to the fastening devices 9.

The aperture 13 is made flexible. The panel 13 is made of plastic. Due to the increase in volume, the diaphragm bends 13 and thus allows movement of the holder 20 out of the housing 10. Even after the increase in volume, the panel 13 is at least partially attached to at least one of the fastening elements 29 or fastening devices 9.

The door device 1 comprises at least two storage groups 40, 50. The electrochemical energy stores 21 are divided into the storage groups 40, 50. By way of example, each of the storage groups 40, 50 includes a plurality, e.g. Each of the storage groups 40, 50 also includes a binding element 41, 51. By the integration element 41, 51 ensures that only the prescribed electrochemical energy storage 21 can be used in the door device 1. An installer is forced by the tie-in elements 41, 51 to replace the envisaged entire storage groups 40, 50 when replacing the electrochemical energy storage 21. As a result, it is denied the installer, only the electrochemical energy storage 21 without the binding elements 41, 51 replace.

The electrochemical energy stores 21 of a storage group 40, 50 are materially connected to the respective integration element 41, 51 of the same storage group 40, 50. For this purpose, the storage groups comprise electrical connections 42, 52. The electrical connections 42, 52 are formed as flags. The electrical connections 42, 52 are materially connected to the electrochemical energy storage 21.

The fastening elements 41, 51 each comprise a board 43, 53. The electrical connections 42, 52 are fastened in particular to the boards 43, 53 in a materially bonded manner. Thus, the electrochemical energy storage 21 and the associated binding elements 41, 51 are each formed integrally with each other. About the terminals 42, 52, the electrochemical energy storage 21 are both mechanically and electrically connected to the respective board 43, 53.

During transport and / or storage of the storage groups 40, 50, the storage groups 40, 50 are electrically isolated from each other. In the door device 1, the storage groups 40, 50, however, are electrically reversibly releasably connected to each other. For this purpose, each storage group 40, 50 comprises at least one electrical connection means 44, 54. For example, the first storage group 40 comprises a plug 44 and the second storage group 50 a socket 54 as electrical connection means 44, 54. The electrical connection means 44, 54 are on the respectively associated Board 43, 53 attached.

The electrochemical energy storage 21 are formed as lithium-ion batteries or accumulators. In particular, the lithium content of the electrochemical energy storage 21 of each storage group 40, 50 is below 2 g. As a result, the storage groups 40, 50 are particularly safe to store and transport.

The connecting elements 41, 51 each comprise further electrical connection means 45, 55. The electrical connection means 45 serves for connection to a connection board 60, via which the electrical energy stores 21 are electrically connected to the control device 5. The terminal board 60 includes for this purpose a connector 61. Also, the electrical connection means 45 as a connector, for. B. as a socket formed. The boards 43, 53 comprise electrical conductors to conduct the electrical current from the electrical terminals 42, 52 to the electrical connection means 45, 54. Further, the boards include electrical conductors to conduct the electrical current from the electrical terminals 44, 55 to the electrical terminals 45, 54.

The electrical connection means 55 is in the in the FIGS. 1 to 5 shown embodiment without function. In principle, however, the electrical connection means 55 is suitable for electrically connecting a further storage group. By the electrical connection means 55, it is possible to form the two memory groups 40, 50 identical. This facilitates the manufacture, storage and installation of the storage groups 40, 50.

Each engaging element 41, 51 each comprise a holding element 46, 56. The holding element 46, 56 serves to receive the board 43, 53. As a result, the electrical conductor of the board 43, 53 protected. In addition, the holding element 46, 56 stabilizes the circuit board 43, 53 mechanically. The holding element 46, 56 is reversibly detachably connected to the circuit board 43, 53, in particular clipped.

The holding elements 46, 56 comprise connecting means 47, 57, by which the holding elements 46, 56 are mechanically connected to one another after insertion into the door device 1. The holding elements 46, 56 comprise further connecting means 48, 58 which can serve for connection to further holding elements. The other connecting means 48, 58 are in the in the FIGS. 1 to 5 shown embodiment without function. In principle, however, the further connecting means 48, 58 are suitable for mechanically connecting a further storage group. By means of the further connection means 48, 58, it is possible to form the two storage groups 40, 50 identically. This facilitates the manufacture, storage and installation of the storage groups 40, 50.

The holding element 46, 56 is dimensioned in such a space that the holding element 46, 56 jammed in the holder 20.

The holding elements 46, 56 comprise side parts 70, which prevent a tilting of the storage groups 40, 50 in the holder 20.

The fastening elements 41, 51 comprise connecting elements 49, 59 for mechanical fastening to the mounting 20. The connecting elements 49, 59 are designed as openings 49, 59. The opening 49, 59 is formed both in the respective board 43, 53 and in the respective holding element 46, 56, so that a mushroom-shaped attachment piece 62, z. As a screw, can be fixed by the binding element 41, 51 to the bracket 20.

The openings 49, 59 are tapered. The mushroom-headed attachment piece 62 may be fixed in the holder 20 even before the storage groups 40, 50 are inserted. When inserting the storage group 40, 50, the wider part of the opening 49, 59 can receive the attachment piece 62. The attachment of the storage group 40, 50 with the holder 20 is effected by moving the storage group 40, 50 according to the direction of the arrow 101 such that the attachment piece 62 is received in the tapered part of the opening. The tapered part of the opening 49, 59 has small spatial dimensions than the mushroom head of the attachment piece 62, so that the storage group 40, 50 forms a positive connection with the attachment piece 62.

By moving the storage group 40, 50 under the attachment piece 62 an electrical connection is made at the same time.

The memory groups 40, 50 can first be joined together and then used together in the housing 10. However, the storage groups 40, 50 can also be used individually in the housing 10 and be connected to each other in the housing 10.

For electrically and mechanically connecting the storage groups 40, 50 inside or outside the housing 10 with each other, the storage groups 40, 50 are shifted into each other.

If the storage groups 40, 50 are inserted successively into the housing 10, the first storage group 40 is first inserted into the holder 20. In this case, the wider part of the opening 49 receives the corresponding attachment piece 62. Then, the storage group 40 is displaced in the direction of the arrow 101, so that the tapered part of the opening 49 forms a positive connection with the attachment piece 62. By shifting in the direction of arrow 101, an electrical connection of the connection means 45 to the connector 61 is produced at the same time. Thereafter, the second storage group 50 is inserted into the holder 20. Here, the wider part of the opening 59 receives the corresponding attachment piece 62. Then, the storage group 50 is displaced in the direction of the arrow 101, so that the tapered part of the opening 59 forms a positive connection with the attachment piece 62. At the same time, an electrical connection of the connection means 54 of the second storage group 50 to the connection means 44 of the first storage group 40 is established. At the same time, a mechanical connection of the first and the second storage groups 40, 50 is produced by the connecting means 47, 57.

If the memory groups 40, 50 are simultaneously inserted into the housing 10, the memory groups 40, 50 are first connected to one another outside the housing such that an electrical connection of the connection means 54 of the second memory group 50 to the connection means 44 of the first memory group 40 and simultaneously a mechanical connection of the first and the second storage group 40, 50 by the connecting means 47, 57 is made. Thereafter, the storage groups 40, 50 are inserted into the holder 20. In this case, the wider parts of the openings 49, 59 respectively receive the corresponding attachment piece 62. The storage group 40 is then displaced in the direction of the arrow 101 so that the tapered parts of the openings 49, 59 form a positive connection with the respective attachment piece 62. By shifting in the direction of arrow 101, an electrical connection of the connection means 45 to the connector 61 is produced at the same time.

The holder 20 remains in the housing 10 during a replacement of the storage groups 40, 50. In particular, the attachment pieces 62 remain in the housing 10 during a replacement.

To replace the discharged electrochemical energy storage 21, it is therefore sufficient to remove the panel 13 from the rest of the housing 10 and perform one of the described procedures.

The electrochemical energy stores 21 are spaced from the board 43, 53 by the electrical connections 42, 52. As a result, a heat input is reduced in the electrochemical energy storage of the rear wall 22 of the holder. In other words, the width b of the binding elements 41, 51 is greater than the width of the electrochemical energy store 21. Thus, the electrochemical energy stores 21 are spaced from the side walls 25, 26 of the holder 20 , As a result, a heat input into the electrochemical energy storage 21 of the side walls 25, 26 of the holder 20 is avoided.

The holder 20 is formed in several parts. In particular, each part of the holder 20 accommodates a storage group 40, 50. Due to the multi-part holder 20, it is possible to pivot the parts of the holder 20 at the volume magnification individually. For this purpose, in particular the triggering device 30 may be divided accordingly.

In the FIGS. 6 to 8 a second embodiment of a door device 1 according to the invention is shown. In the FIGS. 7 and 8 Essential elements of the door device 1 are shown. This shows the FIG. 7 the arrangement below the triggering temperature. In the FIG. 8 is the case of a fire shown. As far as the elements of the second embodiment correspond to the first embodiment, these are designated by the same reference numerals. In the following, the differences from the first exemplary embodiment are discussed and, moreover, the first exemplary embodiment is referred to.

Unlike in the first embodiment, no layer of intumescent material is attached to the holder 20. Rather, the holder 20 is pivotable about an axis 80 and is arranged under bias of a spring element 87 in the housing 10. For example, the spring element 87 may be arranged on the axis 80. The spring element 87 acts on the holder 20 in the direction of movement 100. The holder 20 is held in the first position by a positive locking means 84 (see FIG. FIG. 7 ). The positive locking means 84 comprises a projection 85, which holds the holder 20 against the direction of movement 100 and thus against the force of the spring element 87. Here, the positive locking means 84 assumes a first position. The positive locking means 84 is held by a spring 86 in the first position.

The holder 20 is formed without side walls. The holder 20 is formed substantially as a bent sheet metal. There, where the holder 20 is bent toward the panel 13, fastening elements 29 are arranged for fixing the panel 13 on the holder 20. There, where the holder is bent toward the mounting plate 12, the electrochemical energy storage 21 are arranged. In this case, the memory groups 40, 50 were off FIG. 5 used.

The triggering device 30 is located on the rear side 11, in particular on the mounting plate 12. Here, the triggering device 30 is arranged in the housing 10. Thus, the triggering device 30 is fixed to an inner surface of the back 11. The triggering device 30 is formed of intumescent material. At the release temperature, the volume of the triggering device 30 increases abruptly, in particular by a multiple. The increase in volume can be continued above the triggering temperature. At the triggering device 30, a bolt 81 is supported (s. FIGS. 7 and 8 ). A lever 82 is supported on the bolt 81. The lever 82 is formed with two arms. The lever 82 is pivotally mounted about an axis 83.

During the increase in volume of the triggering device 30, the bolt 81 is displaced. In this case, the pin 81 actuates the lever 82. The lever 82 in turn displaces the interlocking means 84 against the force of the spring 86 from the first position. As a result, the positive connection of the projection 85 with the holder 20 is released, so that the holder 20 can extend with the electrochemical energy storage 21 by the force of the spring element 87 from the housing 10. In this case, the holder 20 is pivoted about the axis 80. Also, the aperture 13 is pivoted together with the holder 20.

The invention is not limited to the described embodiments. For example, the first and second embodiments may be combined. Starting from the second embodiment, the spring element 87 may be missing and instead on the rear wall 22 of the FIG. 6 shown holder 20, a further trigger element 30 may be arranged, which moves the holder 20 from the housing 10 by an increase in volume, and it is described for the first embodiment. On the other hand, starting from the first embodiment, the elements 24 of the holder 20 from the FIGS. 1 to 4 , in particular the elements 242, at least partially missing. Instead, the holder 20 may be provided with at least one projection 85, as in FIGS FIGS. 7 and 8 shown to be mounted below the triggering temperature in the housing 10. Another trigger element 30, as well as it in the FIGS. 7 and 8 is shown and described to the second embodiment, can cancel the positive connection with the projection 85 at the release temperature.
