DE8208835U1 - BAR FITTING FOR A PANIC LOCK - Google Patents

Description

The invention relates to a bar fitting for a panic lock with the features according to the preamble of the claim Panic locks are used in the level on doors that must also be able to be opened from the inside, if they are from the outside are locked. In order to prevent the door handle from being blocked from the inside in panic situations, are on such doors bar fittings are provided with which the actuation of the lock at any point across the door is possible.

A construction of such a rod fitting is known in which the cross rod is directed obliquely downward with lateral Operating levers on two to be attached to the door Door signs is rotatably mounted. This crossbar can be pivoted downward to a limited extent against a return spring. Via the rotary movement of a lateral operating lever, an intermediate gear, which consists of a There is a rack and a gearwheel, which rotates the handle pin arranged vertically in the door plate, via which the unlocking function is carried out the panic lock takes place. The actuating lever engages with one arranged on the side opposite the crossbar Drive lever into a recess in the rack and lifts it during the pivoting movement, which causes the trigger pin moving gear is twisted. Depending on the type of panic lock used, the rotation angle ranges of the handle pin are between 23 - 92 ° required. Such bar fittings are used both on single doors and on double doors. at Double doors use different fittings for the inactive leaf and the active leaf.

This known rod fitting with long door plates is relatively bulky, since it takes up a considerable amount of space for the gear mechanism used consists. The gear used is expensive. The right-left use of such a fitting corresponding doors are only possible to a limited extent.

The object of the invention is to propose a structurally simple rod fitting with a rack and pinion gear for a panic lock _; right-left use should be possible with the corresponding components of such a fitting.

The object of the invention is achieved with a rod fitting with all the features of claim 1.

Depending on the type of translation selected between the rack and the gearwheels, the rod fitting according to the invention achieve the desired angle of rotation ranges on the handle pin between 23 and 92 °. The selected rack and pinion gear enables relatively small dimensions of the correspondingly designed housing-like door plate. In such a housing-like trained door plate can be on the other side of the rod fitting in a simple manner accordingly accommodate necessary bearing parts and the necessary return spring in a favorable manner, so that both bearing housings of the The outside of the door plate have roughly the same appearance.

According to the invention it is also proposed that the transmission to form the receiving door plate in two parts, with a lower door plate part, for example, under the actual bearing housing with keyhole recess, below.

Both door plates, which are preferably used to form a bearing housing have an L-shaped profile, are covered with a corresponding plastic cap, on the lock side both the bearing housing and the lower door plate part can be covered by a common cap.

All essential metal parts of the door plates of the bearing housing and the gear can be used as simple stamped parts produce and thus result in an inexpensive construction. The profiles of the bearing housings can be used right-left, so that the construction only requires little storage effort requires. The construction according to the invention can be used especially in connection with a short door plate.

Further advantages and inventive features are based on an embodiment of the invention explained in more detail below. It

A so-called panic lock is opened by actuating the downwardly pivotable crossbar. These Cross rod 1 is slipped onto the pin 12 of the lateral actuating lever 11 and therefore with a corresponding length to the adaptable to local conditions. The actuating levers 11 are connected to the gear segments via lateral connections connected, which are mounted with journal 13 in housing-like door plates 3 and 3_ ^. The real one Bearing housing 32 or 32 'is each formed by L-shaped stamped profiles. These profiles are attached to the door leaves with screws 2.

The bearing housing 32 provided on the door plate 3 takes the deflection gear on. The gear segment 14 moves a rack 5 when it is rotated, each on adjacent sides has a toothing 51 and 52, respectively. The gear segment 14 engages in the toothing 51. About the gearing a second gear 6 connected to the handle pin of the lock is rotated. This gear 6, which in a Vierkantaufnähme 61 the trigger pin positively receives, so rotates the trigger pin in the necessary rotation angle range determined by the transmission ratio. The rack 5, which slides on a plate 7 on the housing, is therefore the intermediate element between the one with the actuating lever 1 . 11 connected drive gear segment 14 and the

second gear segment held concentrically on the pusher pin or gear 6.

This gear 6 is received in a housing-like bearing disk 4 with a bearing ring on the door plate 3.

A bearing housing is located on the other door plate 3 'in the same way 32 "is formed from a corresponding L-shaped profile. In this bearing housing 32 ', the Operating lever stored with its connections. Supports itself between the housing 32 'and these lateral connections the return spring 8 from.

Both door plates 3 and 3 'have corresponding plastic caps 31 or 31 'covered. It is for the two-part door plate 3, on which a lower plate part 33 is placed below is, a common cap 31 is provided.

The bearing housings can be made of other profile designs, e.g. U-shaped, so that a double storage of the connections, which also serve as bearing journals, is possible. The resetting can then take place via leg springs which are located around the respective bearing pin, with one leg on the Gear segment is firmly clamped and the other is supported on the housing or an adjustable sheet metal, whereby the spring preload can be regulated.
