Description

Technical area

The invention relates to a lock, in particular automatic lock, with a device for activating or deactivating a daytime function in the lock, in particular in the automatic lock, wherein the lock comprises locking elements which can be actuated by means of a push rod, and wherein the device comprises a rotary switch protruding through the forend comprises, whose axis of rotation is normal to the forend, and which cooperates via at least one control projection with a corresponding recess on the push rod to block this when activated daytime function in its unlocked position, and wherein the rotary switch has at its side facing away from the forend inner free end retaining projections , which engage behind the push rod respectively in the activated and deactivated position of the rotary switch, whereby the rotary switch is held within a receptacle in the forend.

State of the art

Such a device is for example in the EP 2151536 A disclosed. The rotary switch shown here extends through the forend and the push rod and interacts with two different stop surfaces on the push rod to block them in two different unlocked lock positions and thus to enable the setting of a tag function.

By day function is meant that by means of a switch, which is usually arranged on the forend of a lock, the relevant lock can either be locked normally or, with the day function activated, all locks can be locked in the unlocked position so that unimpeded access is possible at any time.

For automatic locks, in which when closing the door next to the case and the locking elements automatically in are brought to the locked position, a day function switch significantly increases the possible functionality of such locks, since the automatic function can be repealed, and then the lock can be operated like any other normal lock.

Brief description of the invention

The object of the invention is to improve a device for activating and deactivating the day function to the effect that it is simple in construction and therefore inexpensive to manufacture. In addition, it should be possible to retrofit existing locks in a very simple way with a daily function switch.

This object is achieved in that in the unlocked position of the push rod and in an intermediate position of the rotary switch between activated and deactivated position, the retaining projections are aligned with the recesses in the push rod, whereby the insertion and removal of the rotary switch allows ist.Für the retrofitting of the day function existing locks so only a single component, namely the rotary switch, must be inserted into a recess in the forend. The rotary switch penetrates the push rod and engages behind this with its holding projections, whereby it is secured by the push rod in its receptacle. So there are no additional fasteners needed and the rotary switch can also be made correspondingly flat, so that no further modifications to the frame are necessary. To insert the push rod is raised to the unlocked position and inserted the rotary switch in a slightly rotated position to its deactivated position in the recess. In this position, the retaining projections are aligned with the recesses of the push rod. Once the rotary switch is inserted, it is either rotated to its deactivated or activated position. In both end positions, respective holding projections engage behind the push rod and the rotary switch is thereby secured in the forend.

Another feature of the invention is that the rotary switch has at its face-side end a collar whose diameter is greater than the diameter of the receptacle of the rotary switch in the forend. The rotary switch can, if space available, be located directly in the lock housing or, if it is a lock with multiple locks, also at any other position along the push rod on the forend. So that the rotary switch can not be pressed into the forend, it is advantageous that it is secured by a corresponding collar on the face-end.

According to a further feature of the invention, it is provided that the rotary switch has a handle, for example in the form of a radially extending web or slot, at its outer side on the free end. The operation of the device is characterized in a very simple manner, for example, by hand or by using a coin allows.

It is also a feature of the present invention that the rotary switch has two radially projecting from the axis of rotation, opposing control projections which engage with activated Tagfunktion and corresponding position of the push rod in respective recesses in the push rod. The push rod must be modified only slightly in this very simple design. It has an elongated receptacle through which the rotary switch extends and along the side walls of the receptacle two corresponding recesses, for example in the form of notches, in which the control projections can intervene when the day function is activated.

In one possible embodiment, it is a further feature of the invention that the rotary switch has at its distal end facing away from the forend four radially projecting from the axis of rotation retaining projections, each opposite to two retaining projections and two of the retaining projections extend in the same direction as the control projections , Both in the activated and in the deactivated position of the rotary switch thus engage behind each two retaining projections the side walls of the receptacle in the push rod and secure the rotary switch in the forend.

Another feature of the invention is that the rotary switch is integrally formed. The rotary switch can thereby be manufactured very inexpensively, for example in the form of a casting.

Description of the embodiments

In the Fig. 1 illustrated longitudinal sectional view through a faceplate 2 with a push rod 1 shows the area of the rotary switch 3, which forms the means for activating and deactivating the day function. In the example shown, the rotary switch 3 is outside, for example, above a lock, by means of which the push rod and the associated locks (not shown) are actuated. The rotary switch 3 can thus be easily retrofitted to a variety of locks, without any modifications to the lock itself would be necessary. The rotary switch 3 is inserted in a receptacle 7 in the forend and is secured against falling out by holding projections 6, which engage behind the push rod 1. Against pushing the rotary switch 3 is secured by a collar 8, which projects beyond the receptacle 7 in the forend 2 at the outer free end of the rotary switch. At the outer stulpseitigen free end has the Rotary switch 3 further comprises a handle 9 in the form of a recessed web, by means of which the rotary switch can be rotated between its deactivated and activated position.

In Fig. 2 and Fig. 3 a possible embodiment of a rotary switch 3 is shown in detail. At the outer free end of the collar 8 and the handle 9, on the inner stulpabgewandten free end of the rotary switch 3 holding projections 6 are arranged. In the connecting portion between tax projections 4 are arranged, which, depending on the position of the rotary switch with corresponding recesses 5 (see Fig. 4 ) interact with the push rod 1.

In Fig. 4 is a faceplate 2 viewed from the side of the push rod 1 from. In the area of recording 7 (see Fig. 1 ) is provided in the push rod 1, a slot through which the rotary switch 3 protrudes. The retaining projections 6 engage behind the side walls of the slot to secure the rotary switch 3 in its receptacle 7. The figure shows the position when the day function is activated. The control projections 4 engage in lateral recesses 5 of the push rod 1 and block it in the unlocked position. The recesses 5 are in the example shown two lateral notches in the slot of the push rod 1. When deactivated day function of the rotary switch 3 is rotated by 90 ° and the control projections 4 thus come to rest within the slot of the push rod 1, which in turn free between locked and unblocked Position can be moved. The retaining projections 6 continue to secure the rotary switch 6 in its receptacle 7th
