Description

The invention is based on a door terminal with emergency button according to the Preamble of claim 1. In a housing of the door terminal is a Profile cylinder with an associated electronic circuit, a acoustic alarm and / or visual display means and a Emergency button in conjunction with a switch block for unlocking a Locking device arranged, one in a cover frame covering the emergency button covers.

Such door terminals find as a compact facility of emergency exits in access monitored environment application. Such a door terminal has come under the name "DORMA TL-G" on the market. In a stationary mounted in the door area housing is located Profile cylinder used for alarm acknowledgment and arming / arming of the door serves. Furthermore, LEDs are for the operating state "secured / unlocked" integrated in the housing. In the case are the another alarm and emergency button plus positive opening Housing block housed. That on a wall-anchored to the wall Base mounted housing is by means of a sabotage contact protected. The emergency button is off with a non-splintering protective cover Plastic provided against unintentional actuation. Through a strong blow break in case of danger spacers of the protective cover while the emergency button is depressed simultaneously. The door opens then open almost without resistance, with an audible alarm is triggered.

From DE 196 52 348 C2 also a door terminal is known. In its housing is an emergency button, optical as well as acoustic Display means, an electronic circuit and an insert for Access authorization arranged. To the realization of different Access systems while maintaining the other components too permit, the use for access authorization is modular replaceable executed. The emergency button is also not by a covered splintering protective cover.

In addition, from DE 94 08 898 U1 a hazard detector is known become, which both acoustic and optical display means having. An internal emergency button is against erroneous operation protected by a glass, which is used to trigger alarm manually must be destroyed.

In DE 38 41 099 C2 a door guard is described in which the Obtaining the access of an emergency button the housing to cover This button can be swung aside. An abusive Actuation of the housing is prevented by a cover, the in case of danger, however, must be destroyed.

The operation of the emergency button requires in all of the above Prior art known terminals exchange the then destroyed cover, that is, it creates a corresponding Storage costs for new covers and the resulting Maintenance work. Operator side are in particular the by Abusive operations caused maintenance expenses undesirable. By using glass covers instead of Plastic covers will be the inhibitor of abuse though increased, destroyed the fundamental problem of the exchange Covers, however, remains unchanged. Due to practical However, experience and various guidelines will be a cover of the Emergency buttons recommended to prevent accidental actuation of Alarm devices at least largely avoided.

The invention is therefore based on the object, a door terminal after develop the preamble of claim 1 so that a optimal and disassembly safe arrangement and design of Protective screen with regard to user-friendliness and safety is created, the operator side a low maintenance and Installation effort required. The door terminal should be both for the Surface mounting as well as for flush mounting suitable.

The object of the invention is achieved in that the emergency button a Door terminal by a fitted with an integrated protective screen Cover frame is coverable, preferably at an associated Mounting frame is attached, with the protective screen in one resilient receptacle arranged inside in the cover frame is. In case of alarm, the protective screen is under a defined Operating force with clearly noticeable locking sensation non-destructive axial or pivoted out. About the now in the direction of actuation freely movable protective screen is pressed the emergency button. The Protective glass is thus not destroyed and can by the Maintenance staff later pushed back to the original position become. The protective screen is in the actuation case within the Cover frame passed through a disc slot and from End stops prevented that they open the Cover frame accidentally falls out of the disk shaft. The yielding arrangement of the protective disk in the cover frame is done also under the aspect of the reduction of the damage potential and to reduce the risk of injury to users. Glass is over the variant of plastic preferable because the threatening Danger of injury, the inhibition threshold for abusive actuation elevated. Basically, however, the risk of injury is excluded, because the protective screen in a sufficient material thickness, at usual operation does not splinter, is formed.

Basically, all materials for such Use protective glass that is transparent and that when pressed not be destroyed. Suitable and field tested are glass and Plastic, which is also easy to use with operating instructions or print different information.

The operator side is the reusability of the protective screen and the low maintenance cost advantage. Furthermore, let yourself simply retrofit existing systems with cover frames. By different dimensions from the inside to the cover frame trained holding arms, the operating force on various legal or fire protection specifications be adjusted.

The support arms are preferably at additional opposite Longitudinal walls are cut free within the cover frame. The Retaining arms each have only one elastically resilient connection Longitudinal wall and an inward curvature on. Between the Curvature and an inner edge of the cover is in the unactuated Condition the protective screen. When pressure is applied, the retaining springs spring outward and the protective screen can over the vault on the Emergency button pressed. The longitudinal walls form during the Movement of the protective disk made a shaft in which the Protective cover is guided. The movement gets through to the Longitudinal walls trained end stops limited. The return The protective screen is only possible for maintenance personnel, as only this is able to protect the anti-abuse cover from fold down the mounting frame.

The mounting frame together with the cover frame a modular assembly, wherein the mounting frame under light Pressure is clipped into the terminal housing. The clip connections are made inaccessible from the outside, so that even when open Cover frame a non-destructive disassembly is excluded. Basically, the module is designed so that it is rotated by 180 ° relative to the folding direction of the cover frame in the housing of the Door terminals can be used. The electrical and mechanical Devices in the door terminal are for such an installation variant designed.

The unauthorized opening or removal of the cover frame can be complicated by suitable mechanical means and / or by electrical means providing a silent alarm in a control center or in trigger the display module, be signaled so that immediately appropriate action can be taken.

The hinged cover frame is pivotally articulated on pins of the Mounting frame attached. While closing, enter Recesses on the free moving side of the cover with complementary snap hook of the mounting frame in engagement, while projecting trained above the cover frame Protrusions inside the terminal housing engage behind. Of the The cover frame is additionally protected against abuse Bar blocked, which is driven by the profile cylinder. After a Operation of the emergency button, this blockade only authorized Persons reset. In conjunction with the joint-side Projections can thus be abusive and non-destructive Disassembly of the cover can be excluded.

When the lock is deactivated, it becomes inadvertent Move the cover frame by the locking between the Snap hook and the recesses prevents the beyond an exact positioning of the cover over the Allow mounting frame.

This exact positioning is essential for reliable operation the board located optional sabotage contact required, the z. B. is executable as a microswitch or reed contact. Of the Sabotage contact is via a nose located on the cover frame actuated.

All optical display elements can also and thus centrally in the module will be integrated. It creates a compact and therefore reasonably priced unit that respects the use of the existing Room is optimized in the housing of the door terminal. The order the display module in the emergency button is in particular the Service staff the ability to view all the visual indicators of the module and in addition to capture the lighting of the emergency button at a glance.

The interchangeability of the display module reduces the one to be operated Storing costs at the manufacturer or supplier and allows the Retrofitting a basic version with the least possible effort. The total wiring in the door terminal is standard wiring carried out so that a module exchange only a slight adjustment required. In addition, the door terminals have one uniform appearance.

FIG. 1 shows the basic construction of a door terminal 10 seen. In a stationary mounted in the door area housing 11th is on for alarm acknowledgment and free / -starter serving profile cylinder 20. In the housing 11 are further a acoustic alarm 30 and an emergency button 40 together with not shown accommodated positively opening switching block. For the purpose of fast Localization of the door terminal 10, the emergency button 40 is lit and the Housing 11 z. B. painted green. The on a positive and positive Housing 11 attached to the wall is by means of protected by a sabotage contact. A display module 50 is in the Housing 11 of the door terminal 10 used and not shown by means Plug connections connected to the basic circuit. The Display module 50 consists of a rectangular board 54, on which circular display means 51, z. B. in the form of different colored LEDs and flashing lights are located. One order the emergency button 40 arranged light ring 52 and the outside on one Mounting frame 55 fortified light rods 53 distribute the light. The Such assembled board 54 is located in the mounting frame 55. A Cover frame 60 with the protective disk 61 arranged therein closes the mounting frame 55, so that a complete display module 50th arises. The mounting frame 55 and the cover 60 are made made of translucent material.

The cover frame 60 is pivotally articulated to the mounting frame 55 articulated and has inside two opposite longitudinal walls 62nd on. From each longitudinal wall 62, two retaining arms 63 are cut free, the are formed with inwardly directed bulges 64. In the unactuated Condition (Figure 2) is the protective disk 61 between the vaults 64th and an inner edge 65 of the cover frame 60.

In case of alarm, the protective disk 61 is under a defined Actuating force with clearly noticeable catching feeling, axially non-destructive detached from the resting position. (Figure 3). About now in Actuation direction freely movable protective disk 61 is the emergency button 40 actuated. When pressure is applied, the retaining arms 63 spring in free cuts 66 outward and the protective disk 61 can on the bulges 64 on the emergency button 40 are pressed. The longitudinal walls 62 form during the movement of the protective disk 61 a shaft 67, by the Protective disk 61 is guided. The movement gets through to the Longitudinal walls 62 formed end stops 68 limited.

The thus triggered signal causes on the one hand an acoustic and on the other hand, a visual alarm. The visual alarm is carried out by means of Display means 51, wherein the emitted light in particular on the Light guide 52, 53 is emitted and distributed.

The return of the protective disk 61 in the rest position is only by the maintenance personnel possible, since only this is able, the against Abuse secured cover frame 60 from the mounting frame 55 to to solve. The abusive release of the cover 60 causes over one between the cover frame 60 and the mounting frame 55th arranged micro-switch (not shown) a silent alarm in a Control center and / or a corresponding signal in the display module 50. If mechanical securing means between the cover 60th and the mounting frame 55 and the housing 11 are present, can an abusive dismantling only by destruction of the concerned Components take place. Authorized personnel can use the cover frame 60 without triggering the signal. The microswitch is connected via a additional key position of the profile cylinder 20 free or armed.

The housing 11, which designed for surface and flush mounting is, is designed such that all for the operation of the various display modules 50 necessary connections available and the display modules 50 are by authorized personnel are interchangeable.
