Description

The present invention relates to a transmission for a panic door lock and the panic door lock itself.

Panic door closures are used to quickly leave endangered rooms or buildings and are used on corresponding escape doors or panic doors.

An art of panic door closures known in the art is constructed to have an actuator (a so-called panic bar) which extends over a large portion of the door width and to which side pivot arms are attached. Upon actuation, the actuator is pressed in a pivoting movement in the direction of the door. This pivoting movement of the actuating element must be converted into a rotational movement of a square receptacle (a so-called nut), because the lock is coupled in and opened via this square receptacle by means of a so-called push-pin. For this transformation of the pivoting movement in a rotary motion of the square drive transmissions are often used, which can be configured differently.

A generic example of a corresponding fitting disclosed DE 83 28 207 U1 , in which a panic bar handle fitting for the operation of door locks is described. This has an approximately over the door leaf width extending handle bar, which is held at both ends of levers, which are each pivotally mounted on a door leaf side attachable bottom plate. The handlebar is pivotable against a spring force on a bearing plane. A movable closing part of the lock is connected via a spring-loaded rack and a gear meshing with this meshing gear. The levers cover labels that form a box-like door fitting plate. The two levers are each held on a lower plate via a spherical plain bearing, whose one bearing part is pivotable to another in addition to a rotational movement in a spherical angular range.

Another generic example of a transmission is in DE 10 2005 029 452 A1 described, according to which the transmission has a base member with guide sleeve, a rotatably mounted in the guide sleeve square socket, a coupling element for connection to a handle and transmission elements for implementing a component of movement of the coupling element in a rotational movement of the square socket. In this case, guide sleeve, coupling element and transmission elements are arranged in a special geometry to each other.

Panic door closures are subject to various requirements. Thus, the required force on the operating rod to open the door should be as low as possible, so that children and the elderly in an emergency, the panic door can open quickly and easily. According to DIN EN 1125 For example, a maximum opening force at 1,000 N pressure on the door of 220 N or no load on the door of 80 N is specified. In the prior art, these opening forces are often realized in such a way by panic door locks are used with a large tilt angle.

However, the solutions known from the prior art have some disadvantages. To ensure such a large tilt angle, the handle bar must protrude very far from the door leaf. Furthermore, large-volume gearboxes are used to ensure smooth running. The opening of the panic door takes by exceeding a larger swing angle, however, longer, which is not desirable, especially in case of panic. In addition, the greater distance of the handle bar from the door leaf can lead to problems when opening the panic door.

Due to the installation situation, the panic door lock, or its gear and / or handle bar in Einflügligen doors on the door frame or double-leaf doors on the inactive leaf or on the handlebar of the inactive leaf when both sides are opened, abut. This can happen, in particular, when frame doors with very narrow frames are used and the square seat of the lock sits close to the front of the door, d. H. if the doors have a small backset, or if they are narrow door leaves. However, such an abutment must be avoided at all costs, since in the worst case scenario it can block the panic door and thus its inactivity.

Further disadvantages of a protruding far from the door leaf handle bar are a risk of injury by bumping or snagging and a visually impaired appearance, especially in the case of high-quality doors in representative spaces.

Based on the above-mentioned disadvantages of the prior art, the present invention seeks to provide a transmission for a panic door lock and a panic door lock, with which it is possible to reduce the supernatant as much as possible and even with narrow frame structures of the panic door to ensure trouble-free opening, while at the same time the opening of the panic door with a small pivoting movement is ensured as quickly as possible.

This object is achieved in a first aspect of the present invention by a transmission ( 1 ) for a panic door lock ( 3 ), comprising

• - a base plate ( 101 ) having a support plane (A) for resting on a door,
• - two on two opposite sides of the base plate ( 101 ) arranged side parts ( 10101a . 10101b ) extending perpendicularly from the support plane (A),
• - one in a guide sleeve ( 10103 ) of the base plate ( 101 ) rotatably mounted square socket ( 103 ) whose axis of rotation is perpendicular to the support plane (A),
• - a reversing lever ( 105 ) rotatably mounted on a bolt ( 107 ) between the side parts ( 10101a . 10101b ) is mounted and has a pivot angle α,
• - one on the bolt ( 107 ) mounted return spring ( 10501 ) for the lever ( 105 )
• - one with the lever ( 105 ) associated lever arm ( 109 )
• At least one slider ( 111 ) for transmitting the pivoting movement of the reversing lever ( 105 ) by means of the lever arm ( 109 ) in a rotary movement of the square ( 103 )
• - a gearbox cover ( 113 ) with a recess ( 11301 ) for the lever ( 105 ) and
• - at least one opening ( 10105 ) in the base plate ( 101 ), which extends to the support plane (A) and extends in the longitudinal direction of the base plate ( 101 ), wherein the lever arm ( 109 ) into the at least one opening ( 10105 protrudes) and the at least one slide ( 111 ) at least partially in the at least one opening ( 10105 ) is guided.

Through the at least one opening ( 10105 ), it is possible with respect to prior art designs to use the lever arm ( 109 ) in this opening ( 10105 ) into almost the surface of the panic door ( 5 ), so that there with the slider ( 111 ) engages and the pivoting movement of the reversing lever ( 105 ) into a larger (ie longer) linear movement of the slider ( 111 ), as can be realized in the prior art. This linear movement of the slider ( 111 ) is then in a rotary motion of the square ( 103 ) implemented. By the arrangement according to the invention are compared to the prior art significantly improved conditions with respect to the leverage and travel of the transmission ( 1 ) realized. Furthermore, the total installation height of the transmission ( 1 ) be reduced.

The term "support plane (A)" in the present invention essentially the underside of the transmission ( 1 ), ie the underside of the base plate ( 101 ), which forms the interface with a door leaf or a surface of a tubular frame door.

The base plate ( 101 ) and arranged on their opposite sides side parts ( 10101a . 10101b ) may preferably be integrally formed, in particular as a punched or lasered and beveled sheet. The lever ( 105 ) and the lever arm ( 109 ) may also preferably be made in one piece, for example as a metal casting.

The side parts ( 10101a . 10101b ) have respectively opposite an opening in which the bolt ( 107 ) is inserted, so that this an axis of rotation for the lever ( 105 ). Also on the bolt ( 107 ) is a return spring ( 10501 ) vorgsehen to the lever ( 105 ) in its rest position. The return spring ( 10501 ) must be dimensioned so that they next to the lever ( 105 ) also at the outer end of the reversing lever ( 105 ) pivoting arm ( 7a . 7b ) as well as at least partially horizontally on the swivel arm ( 7a . 7b ) arranged handle bar ( 9 ) wearing. That means, the return spring ( 10501 ) must be dimensioned so that the weight of the reversing lever ( 105 ) with swivel arm ( 7a . 7b ) and handle bar ( 9 ) not to unintentionally open the panic door ( 5 ) leads.

The slider ( 111 ) is in the base plate and at least partially in the opening ( 10105 ) is slidably mounted and is in one end (ie the lower end) in frictional contact with the lever arm ( 109 ) of the reversing lever ( 105 ). At its other end (ie the upper end) is the slider ( 111 ) in frictional contact (directly or indirectly) with the square socket ( 103 ). The square recording ( 103 ) is always on the slide ( 111 ) and is connected by means of a square pin with the lock nut of the panic lock. This lock nut in the panic lock is again acted upon by a spring, the so-called pusher holding spring.

The gear cover ( 113 ) essentially serves to protect the transmission ( 1 ) against foreign bodies and mechanical damage, as well as the protection of persons from injury. It also serves to position and guide the lock cylinder of the panic lock. In addition, the gear cover ( 113 ) an aesthetic function.

In an advantageous embodiment of the transmission according to the invention ( 1 ) is the pivot angle α between 16 ° and 21 °, preferably at 16 °. Thus, the pivoting angle α is indeed smaller than comparable angle in the prior art, due to the inventive arrangement of the opening ( 10105 ) with slider sliding therein ( 111 ) and thus engaging lever arm ( 109 ) of the reversing lever ( 105 ) is an at least equal linear motion and thus an equal rotation angle of Square socket ( 103 ) reached. This angle of rotation is preferably between 30 ° and 40 °, preferably 30 °.

In order to ensure a more uniform mechanical load of the transmission according to the invention ( 1 ), it has proven to be advantageous if in the base plate ( 101 ) two openings ( 10105a . 10105b ) are provided, which in the edge region of the base plate ( 101 ) are arranged parallel to each other. Here are two parts of the lever arm ( 109 ) of the reversing lever ( 105 ) in two opposite parts of the slide ( 111 ) one. A one-sided jamming of the slide ( 111 ) and / or the lever arm ( 109 ) can be avoided. Furthermore, the square recording ( 103 depending on the type of installation from both sides via the slider ( 111 ), ie, rotated, so that it is possible, the transmission ( 1 ) for left and right locks.

The transmission according to the invention ( 1 ) preferably has a height H of less than 50 mm, preferably less than 40 mm, in particular 38 mm. As described in the introduction, there are always problems with the constraint between transmissions according to the prior art and the door frame or a second door leaf. With the inventively provided low height H but the effective length of the handle bar ( 9 ) can be increased because the constraint is significantly reduced. Nevertheless, the space between the surface of the panic door ( 5 ) and the handle bar ( 9 ) even at the narrowest point at least 25 mm, so that in the DIN EN 1125 is complied with.

As stated above, for the reversing lever ( 105 ) a relatively large-sized return spring ( 10501 ) intended. If the lever ( 105 ) (together with its connected elements) from the counter to the spring force of the return spring ( 10501 ) actuated position, it quickly returns to its rest position, ie against corresponding to the base plate ( 101 ) provided attacks. The disadvantage can be in addition to a disturbing and unpleasant noise, especially the mechanical stress of the attacks and the entire base plate ( 101 ).

It is therefore provided in a development of the invention, between the side parts ( 10101a . 10101b ) at least one damping element ( 115 ) so that the lever ( 105 ) rests against it in its rest position.

Preferably, the damping element ( 115 ) formed from one or more O-rings of a kinetic energy absorbing material, which are mounted on an axis which relative to the stop of the reversing lever ( 105 ) is provided. In this way, a sufficient damping of the kickback is achieved.

• – ein erfindungsgemäßes Getriebe (1), wie es vorstehend beschrieben wurde, das auf der Schlossseite der Paniktür (5) angeordnet ist,
• – ein Lager (301), das auf der Anschlagseite der Paniktür (5) angeordnet ist,
• – einen getriebeseitig angeordneten Schwenkarm (7a),
• – einen lagerseitig angeordneten Schwenkarm (7b) und
• – eine zwischen den Schwenkarmen (7a, 7b) im Wesentlichen horizontal angeordnete Griffstange (9).

The above object is achieved in a second aspect of the present invention by a panic door closure ( 3 ), which includes

• An inventive transmission ( 1 ), as described above, on the lock side of the panic door ( 5 ) is arranged
• - a warehouse ( 301 ) located on the side of the panic door ( 5 ) is arranged
• - A transmission side arranged pivoting arm ( 7a )
• A pivot arm arranged on the bearing side ( 7b ) and
• - one between the swivel arms ( 7a . 7b ) substantially horizontally arranged handle bar ( 9 ).

The panic door lock ( 3 ) has substantially the same advantages as the transmission included therein ( 1 ) on. In particular, it is advantageous in comparison with the prior art that a relatively short actuating travel of the handle bar (FIG. 9 ) in the direction of the panic door ( 5 ), ie a relatively small pivoting movement of the reversing lever ( 105 ), in a larger (ie longer) linear movement of the slide ( 111 ) for rotation of the square ( 103 ) can be implemented. As a result, compared to conventional panic door closures significantly improved conditions with respect to the leverage and travel of the transmission ( 1 ) realized. Furthermore, the total installation height of the transmission ( 1 ) be reduced.

The transmission according to the invention ( 1 ) preferably has a height H of less than 50 mm, preferably less than 40 mm, in particular 38 mm. As described in the introduction, there are always problems with the constraint between transmissions according to the prior art and the door frame or a second door leaf. With the inventively provided low height H but the effective length of the handle bar ( 9 ) can be increased because the constraint is significantly reduced. Nevertheless, the space between the surface of the door and the handle bar ( 9 ) in which in the DIN EN 1125 set down by at least 25 mm.

It is for the panic door closure according to the invention ( 3 ) that the supernatant (W) of the handlebar ( 9 ) is at most 100 mm, in particular at most 90 mm. The supernatant (W) corresponds to the dimension W according to DIN EN 1125 , Compared to known from the prior art panic door locks this supernatant (W) can be significantly reduced.

In particular, by reducing the height H of the transmission ( 1 ) is the panic door lock according to the invention ( 3 ) usable up to a backset of 30 mm. That is, for example, panic doors on the basis of tubular frame doors with forced small backset, which have so far been very difficult to be provided with a panic door lock, by the panic door lock invention ( 3 ) to be updated.

Escape doors on which panic bars are used are often designed as fire and smoke protection doors. In order to find the escape doors in the dark and with heavy smoke, they are marked as such above the door with corresponding escape door symbols. The disadvantage is that although the escape door is marked as such, but not the appropriate handle for their operation (door handle or actuator) to open the door quickly. This can lead to critical time losses during escape from the hazardous areas.

The panic door lock according to the invention ( 3 ) is therefore designed in a preferred embodiment so that on the handle bar ( 9 ) at least one reference element ( 11 ) is arranged, preferably on the transmission-side half of the handle bar ( 9 ). With this hint element ( 11 ), it is possible to immediately open the "right" side of the panic door, ie the lock side.

In an advantageous development of this embodiment, the at least one reference element ( 11 ) self-luminous. Self-luminous in this context means that the reference element ( 11 ) in daylight or when the electric light is switched on and the absorbed energy in the dark in the form of lights again. Thus, regardless of a power supply, which may be out of order in case of emergency, an orientation aid in darkness or smoke, for example, ensured.
