Door lock with a security knob

Insurance companies have been around for many years and various authorities are looking for more burglar-proof locks (this should also include facilities with which an entrance door can be opened from the inside without a key). A door lock which is in authorized Use must be easy to operate. A special feature is that the door lock is easy for the residents should be manageable, i.e. there should be a way to open the lock from the inside without a key lock and unlock. The: fire supervisory authorities can require a quick unlock option a door must be given without the help of a key (- which can be cleared or misplaced).

Safe handling for residents who are at home, is often used by means of a door lock :; achieved, which can be actuated from the inside by a button. Such a door lock meets the requirements of the fire supervisory authorities regarding a quick and safe evacuation.

Home security means that the door is locked by a lock of known design, e.g. B. by a door lock with seven tumblers, which without the right key, neither from the inside nor from the inside can be unlocked from the outside. It is therefore possible to use a cylinder lock that is secure against expansion, where the door is then both on its inside and on its outside (i.e. there is no button on the inside) must have a cylinder.

Many attempts have been made to combine the two aspects of security. Accordingly, it is possible to use a cylinder which can be operated by a key from the outside and a button from the inside, together with a lock with seven tumblers. It is also possible to use a two-function lock that has both a cylinder lock with a button on the inside: the door and a lock * ' ^] with seven or new tumblers. These solutions are satisfactory from the point of view of the fire control authorities, provided that the lock is not locked from the inside with tumblers; or if it is locked, that the key remains in the lock. However, these solutions are not particularly convenient because they require another large extra key (- for the lock with tumblers). Approximately the same effect is obtained with a cylinder lock that is safe to remove and that can be operated from both sides with a key. This solution also satisfies the fire authorities, but only if the key is constantly stuck in the lock when someone is at home.

This solution is advantageous because or is not required, an extra key to carry around on the other side must however be remembered to put the key on the inside of the door and have infected as long as someone is at home.

The aim of the present invention is to satisfy the needs of insurance companies, various authorities including fire supervisors, as well as those of users, with a device used with different types of cylinder locks and with different designs of espagnolette locks for assembling the lock cylinder can. The device includes also referred to herein as a safety button and the place on the inside of \ door a button, an inner lock cylinder arranged ist.s This button provides the requirements of the Insurance Law Student | llschaften and some authorities both in terms of safety of the abandoned apartment as well as the Satisfied user and fire authority requirements for rapid evacuation.

A lock according to the present invention includes a Member, welqhes rotatable within a limited angle of rotation is and with which a displaceable bolt can be actuated. The invention is characterized in that of security sknopf is adapted to a driver which is axially displaceable between two end positions, of which one end position allows engagement with the rotatable member, while the other end position allows detachment from the rotatable member results and rotation of the member blocks a re-engagement. .

The driver is preferably with markings for the Provide settings which have at least one Uiufangsrille to interact with a clamping device, which defines an opening display.

The driver is advantageously provided with two circumferential grooves which cooperate with a spring-loaded ball clamping device for fixing the end position. The driver can be arranged in a bearing cover disk and provided with a flange of sufficient size to cover at least two screws in order to secure the cover disk. The cover plate is advantageously provided on its inside with a recess into which a radially oriented mandrel on the driver can be inserted when the safety button is brought into its other end position. ^:

The lock may include a key-operated lock member fitted to the inside of the door, which optionally engages in a groove in the driver by means of a spring-loaded slide. The slide can with Provide a recess for receiving a radially aligned dome on the driver when the safety button has been brought into another: end position. the The slide can also be designed in such a way that it moves directly into a circumferential groove after the driver has been displaced of the driver engages.

in the embodiment according to FIGS. 1 and 2
the reference number 10 a section of a Türblattcs, in which a lock housing 11 is inserted. The lock contains a rotatable member 12 which is provided for receiving the mandrel, which has a square cross-section, of a handle, which in a known manner (not shown) in a bore 13 in the. Door leaf is fitted.

The lock housing contains a further rotatable member 14, which in a known manner (not shown) by a bolt and is operated by a key by means of a cylinder lock 15 accessible from the outside of the door. The cylinder is provided with a protruding tongue 16, diet constantly into the hourglass-shaped recess in the rotatable member 14 intervenes. :. "*

The cylinder lock is usually by means of two screws
18 attached to the lock housing and the cylinder lock is accessible to the outside through an outer ring 17, which is held by screws 30, accessible from the inside of the door and covered at a subsequent section by a flange 28 on the security button.

On the inside of the door there is a known type Button 19 by means of which the rotatable member 14 can be operated. Q] S, however, is aiming for this button under different Circumstances can be made ineffective, so that an undesired unlocking of the door from the inside is prevented will.

The button 19 is arranged on a cylindrical driver 20

-χ- f-

net, whose hand 20a, which is more distant from the center, is designed in this way is that it is to engage in the opening 29 of the rotatable member 14 is suitable. The length of the driver 20 allows a satisfactory engagement in the threatenable Limb when the button is pushed all the way in.

The driver is provided with two circumferential rilions 21 and 22, which cooperate with a spring-loaded ball clamping device 23 and define the two end positions of the axial displacement of the driver. The äussoro groove 22 is deeper than the inner groove and provides an opening indication that ensures that the withdrawn button 19 through the The carrier is delivered when or: gowaitsam is pressed. The driver then remains inaccessible.

The driver 20 is mounted in a cover film 24 and provided with a sideways mandrel 25. There is a short one on the inside of the bearing cover plate Groove 36 is provided which serves to receive the dome 25 when the safety button is withdrawn. This will the driver is held in the retracted position so that it cannot rotate. '

The overlying cover plate 24 is also equipped with a passage 27 provided, which shows the same extent as the

Mandrel 25. During the assembly of the driver, the driver Pressed into a 180 ° rotated position by the supporting cover plate, i.e. with the mandrel 25 pointing downwards so that the driver moves inwards through the passage can move.

The knob is (sh. ..Tuch figure b) having a flange 28 is provided, having such an extension, ι lanυ or the uuwohJ

Groove 27 as well as those holding the covering disk 24 on top Screws covered.

Figures 3 and 4 show a section through the driver 20 in the direction of view to the rotatable member 14. It will especially on the characteristic design of both the opening 29 and the corresponding one, from the center distant end section 2üa of the driver pointed out. The lock cylinder is on the lock housing 11 by means of screws 18 and covered on the outside by a King 17, which itself is fastened by means of the screws 30 in a manner which is better shown in the following figures.

Figure 3 shows the driver in engagement with the rotatable member 14 and Figure 4 shows the driver in the retracted position from the rotatable member, wherein the rotatable member has been rotated 90 ° by means of a key is.

This figure shows the button 19 looking towards the inside of the door and it is evident that the flange 28 has such an extension that it covers both the screws 30 and the groove 27. The screws 30 can Advantageously, they can be one-way screws, i.e. they can easily be screwed in but no longer screwed out again will. Even if the driver should break on the groove 20, it is possible to remove the screws 30 without To remove tools and labor.

How these screws hold the bearing cover disk 24 on the outer ring 17 can be seen from FIG.

As has been described at the beginning, it is desirable, normally from the outside of the lock by means of a Key and operated from the inside by means of the button. On various occasions, in particular if no one is at home, he should last the house

let the door of the Aussonso i Ic vorch 1 i (': ;;; cn, after he pulled the button into an ineffective Sirol Lung.

The, Figure 7 shows three different basic positions for a normal "at home" function, in Figure 7a the door is unlocked, both the locking tongue 16 and the button 19 remain in the horizontal position.

In Figure 7b, the door was locked from the inside, which is indicated by the vertical position of the button.

Figure 7c shows how the lock by a key 31 has been locked. The driver, which is in engagement with the rotatable member, can move the button in its vertical position Threatened situation. It is of f ons I: .L I make it possible is, by means of a key, from the, outside both in the situation shown in FIG. 7b as well as by means of the button 19 in the situation shown in FIG. 7c to unlock.

Figure 8 shows some possible positions in which the button is withdrawn from engagement with the rotatable member has been. Figure 8d corresponds to the unlocked position, i.e. it is similar to Figure 7a, with the key 31 is plugged in. In Figure 8e, the key has been turned 90 ° so that the bolt protrudes while the button in its horizontal position? remains.

According to FIG. 8f, the key was turned back again so that the door is now locked and only with one key can be opened. The opening 29 in the rotatable member

has been placed in a position in which it is impossible to Re-insert the driver axially. Included the position of the mandrel prevents it 2 '> in KLlJo 26 a rotation of the driver.

Various disadvantages can be asserted against such a closure arrangement, in particular that of anyone could lock someone in the house. The first-mentioned person may or may not click the button carelessly, assuming that no one at home, retire.

such possibility of advance 1. Lessens the door from the inside of what the key is on, intentionally or unintentionally away and in a situation of panic, e.g. B. is not found in the event of a fire, must be assumed will.

In order to meet all possibilities, an additional lock can be fitted on the inside of the door, which can preferably be operated by the same key with which the main lock is operated from the outside of the door will. The convenience of the "at home" position is then achieved by means of the button, using the button if necessary can be unlocked from the inside by a key.

Two designs that allow such an effect are shown in Figures 9 * · 13, in which for same Parts of the above reference numerals are used.

In the embodiment according to Figures 9-11, the Supporting cover plate 24a accommodate a further lock 35 which can be actuated from the inside. The carrier 36 this lock acts by means of a simple rotatable member 37 and a mandrel 38 with a movable up and down Slide 39 together. The slide is biased by springs 40 for engagement with the driver 20.

The end of the upside-down slide is forked towards the driver so that it encloses the driver

can. In addition, the slide has a central recess 41 provided for the mandrel 25 provided on the driver.

FIG. 9 shows how the mandrel 2 5 is arranged within the supporting cover disk 24a, even when the driver is pushed completely inwards. The groove 42 in the bearing cover plate has the same position as that Groove 26 in the embodiment according to Figures 1 and 2, but here it has an angular extent of 180 ° in the manner shown in FIG. In this way it is possible to use the Safety button 19 to make the required rotation in each direction by 90 ° for locking and unlocking.

For the sake of clarity, the slide 39 is shown lifted by the lock 35 in FIG. 10, although the slide is usually pressed by the springs 4 0 against the driver when the driver 20 is withdrawn.

With the help of the key in lock 35, however, it is possible the slide 39 out of engagement with the driver 20 lift, which is then rotated into a suitable position for insertion into the opening in the rotatable member 14 can be so that the driver can be moved axially to engage the rotatable member.

With the modified embodiment according to the figures and 13 it is necessary to always lift the slide 39a in order to adjust the driver 20 in one direction, in particular when the driver 20 is to be brought into engagement with the rotatable member 14. The driver is with a Groove 46 is provided, which in the depressed position of the Driver interacts with a spring-loaded clamping device 45. A spring washer fits in place of a mandrel 25 47 into a groove, whereby the retracted position is

is laid.

The end portion of the slider 39a is arcuate Recess 48 is provided which can be brought into engagement with the groove 46. The recess is so narrow Gap that the slide must be held in the raised position (Figure 13), whereby the section of the slide outside of the gap can be brought to rest on the slide.

When it is desired to secure the lock in the "out of home" position, the button is withdrawn until the spring ring 47 on the driver comes into contact with the overlying cover disk 24b. The end section of the slide 39a slides along the driver and finally engages in the groove 46. The groove extends around the driver so that the knob 19 can be rotated freely but not axially displaced. Can be opened from the inside, for example by means of a * key, rotated so that the follower 20 in the correct position and can be anschlicssend urged into engagement with the rotatable member fourteenth

The last two implementations described are only used when it is desired, inadvertent imprisonment to prevent a person who has access to a door key. The embodiment according to FIGS. 9-11 is a pure safety application, which hopefully will never be used, but which, for example, is used by the fire authorities may be required. The embodiment according to Figures 12 and 13 requires constant activities where an "away from home" effect is to be translated into a conventional "at home" effect.
