Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a lockable mortise lock having a cylindrical lock housing that entirely accommodates a trowel portion, and a locking unit having an axis perpendicularly intersecting the axis of the lock housing.

This type of door lock requires that the door be able to be locked and unlocked by means of a key or a lock button.

In order to meet this requirement, it is known that traditional door locks are actuated via a single lock cylinder or simply interlocked with a lock button.

However, such known door locks have significant drawbacks.

First, such locks are difficult to install depending on the thickness of the door and the condition of the door, and in some cases require the hands of a skilled joiner.

Additionally, placing the lock cylinder and lock grip in the line of motion of the locking bar requires some dexterity.

The latter difficulty is compounded when the locking bar must be recessed into the door thickness and a lock cylinder or closing grip must be installed on each side of the door.

Known so-called safety locks also have the disadvantage that if the door is locked and the key is not removed, it is impossible to open the door using the key from the other side of the door.
There is.

If a door that has been locked in this way has to be opened, for example for police reasons, the door must be broken open or a hole must be drilled into the lock cylinder.

A disadvantage of all known door locks of this type is that it is necessary to check in advance which side of the door the lock is to be mounted on, for example by a button, i.e. the lock cylinder is also This is because the locking bar, which is usually directly connected to the locking button, is not designed to be applicable to both right-handed and left-handed rotations.

It is an object of the present invention to provide a door lock that is easy to assemble.

Another object of the present invention is to provide a door lock that can be attached to a door regardless of the thickness of the door or the mounting situation of the lock.

Another object of the invention is to provide a door lock that is much easier to switch from left-handed to right-handed or vice versa.

It is another object of the present invention to provide a door lock that is already assembled before the locking bar is inserted.

Still another object of the present invention is to provide a door lock that is designed to be able to be modified in various ways depending on the application without changing the main lock elements.

Another object of the invention is to provide a lock in which the lock cylinder is non-rotatably connected to the lock housing.

Another object of the invention is to provide a door lock which is designed so that, depending on the requirements, a key-actuated lock cylinder or a closing head or a combination of both can be used in the same lock.

Another object of the present invention is to provide a mechanically strong and reliable door lock.

Another object of the present invention is to provide a door lock that is easy to manufacture.

Other goals achieved by the door lock of the present invention will become clear from the following description.

All these objects are achieved according to the invention, in which the locking unit is bored in the lock housing and passes through an elongated cutout extending longitudinally along the axis of the lock housing, the cutout being centrally located in the lock housing. This is achieved in that the locking unit extends inwardly as far as the disposed joint shaft and is movable along the axis of the lock housing within the cutout to adapt to the thickness of the door.

In an advantageous embodiment of the invention, the locking unit consists of an approximately cylindrical locking piston, a substantially cylindrical locking sleeve, a spacing screw, a locking spring and a locking sleeve cover sheet, which engages with the coupling shafts.

The advantages achieved by the present invention are, in particular, that instead of making a number of door locks of different designs, one basic lock is made, and in this basic lock there are different fittings and fittings for each application. /
or other operating parts can be attached.

Additionally, each lock can be easily modified or adjusted in the field to determine whether the lock is operated by turning right or turning left.

Two other advantages are made clear by the following explanation. The invention will be explained in detail below by means of exemplary embodiments in the drawings.

FIG. 1 shows a door lock according to the invention which can be used, for example, on the door of a residential building.

This door lock can be locked or unlocked from both sides of the door using a key.

This lock is basically assembled from the parts described below.

A lock housing 10 in the form of a cylindrical pipe has both ends 1
At 01.degree. 102 it has a thread 103, 104 into which a collar 11.12 is screwed, the collar being prevented from loosening and rotation by a plastic part 13, 14, respectively.

According to FIG. 1, the door plate 9 can be of any thickness, i.e. a lock containing all the door lock parts according to the invention.
・Using 10 has a hole 91 in door plate 9 that matches its diameter.
After being inserted into the collar 11. This is because it is easily fixed by 't2.

Each collar 11.12 is at least partially covered by a grip 15.16, which is fixed to the hollow shaft 17 by a grip screw 161.

The grip 15 is also connected to the hollow shaft 17 in a similar manner.

It is immediately obvious that the collars 11 and 12 and the grips 15 and 16 are parts that are visible from the outside of the door lock.

However, even in the assembled lock (see both cylinder sleeves 18.19, cylinder stator 20.21)
, and the cylinder rotor 22, 23, which is surrounded by the cylinder stator and forms a locking part, can also be seen.

Inside the lock housing 10 are housed lock components such as pegs that have various functions.

The two bearing bushes 24,25 each have four blocking grooves 241 and 2, two of which are arranged opposite each other.
51 (Figures 2 and 3).

As shown in Figures 2 and 3 (hollow shaft 1
7 is a pair of similar blocking grooves 171 and 172, respectively.
, which grooves are in the same position and similar to one of the pair of blocking grooves 241, 251 in the bearing bushings 24, 25, only they are slightly longer in the axial direction of the hollow shaft 17.

The hollow shaft 17 is connected to the grip 15.16 as described above, and since the grip 15.16 is rotatable, the hollow shaft is also rotatable.

On the other hand, the bearing bush 24.25 and the cylinder 1)-
7'18 and 19 are cylinder sleeve screws 26°2T
Since it is connected to the lock housing 10 by the lock housing 10, it cannot be rotated.

Of course, in order for the hollow shaft 11 to be able to rotate as described above, the hollow shaft must be connected to the cylinder sleeve screw 26, 27.
It must have slits 173, 174 through which it passes.

two blocking sleeves 28, 29 and two blocking rotors 3
0.31 are the internally adjacent locking parts, of which the blocking sleeve 28.29 holds two blocking pins 292 and 282 which engage into the blocking grooves 171/251 and 172/241. (Figure 3).

The contact surfaces 302/281 and 312/291 of the blocking rotor 30/31 and the blocking sleeve 2B/29 are in the form of cam discs, so that when they rotate relative to each other, the blocking sleeve 28.29 The blocking pin 282.292 is reciprocated together with the blocking pin 282.292, which is firmly connected to the sleeve, so that in the end state near the center of the lock, the blocking pin 282.292 engages the blocking groove 1 of the hollow shaft 17.
72.171 and in the other outer end state the blocking groove 241.251 of the bearing bushing 24.25.
Then, it enters into both the blocking grooves 172 and 171 of the hollow shaft 17.

That is, a hollow shaft that is rotatable in nature. Blocking pin 2
82.292, the blocking sleeve 28, 29, which is connected in a relatively non-rotatable manner to the hollow shaft, is rotatable only when the blocking sleeve 28, 29 is in its end state near the center of the lock, and the blocking pin 282
．． 292 is the blocking groove 241.2 of the bearing bush 24.25.
51, rotation of the blocking sleeves 28, 29 and the hollow shaft 17 is no longer possible, since the bearing bushings are connected to the cylinder sleeve screws 2.
This is because the lock housing 10 is firmly and non-rotatably connected to the lock housing 10 by 6.27.

The blocking rotors 30 and 31 are identical (having a recess 303, 313, respectively, on the side facing the center of the lock, which in cooperation with the set screw 37 determines the angular range of closing rotation of the door lock). ing.

The blocking sleeves 28, 29 each have a blocking sleeve spring 32.
．． 33 cooperate and these springs block the blocking sleeve 28.2.
9 contact surface 281.291 and blocking/stopping rotor 30.31
The blocking sleeve is pressed so that its corresponding contact surfaces 302 and 312 are always in contact with each other.

Blocking sleeve springs 32, 33 are attached to cylinder stator 20.
21, and the cylinder stator itself is supported by a safety pin 201.211 and a cylinder sleeve screw 26.2.
7 are connected to the bearing bushes 24, 25 and thus also to the lock housing 10.

Therefore, the cylinder stator cannot rotate.

The blocking sleeves 28, 29 on the one hand hold the blocking rotor 3
0.31 on the pipe section 301.311 and on the other hand between the blocking rotor 30.31 or its pipe section 301.311 and the joint section 221.231 of the cylinder rotor 22.23. 35
Exercise above.

The blocking rotors 30 and 31 are mounted on a coupling shaft sleeve 36 which has a coupling groove 361, 362 at each end thereof and a cutout 9 section 3 approximately in the middle thereof.
63 and blocking segment 42.

The coupling shaft sleeve 36 is connected to the blocking rotor 30.31 in a rotationally fixed manner.

Inside the joint shaft sleeve, a joint shaft 38 having two joint pins 381 and 382 on one side is located, of which the joint pin 381 is always connected to the joint part 221. , the coupling pin 382 is coupled with the coupling shaft sleeve 36 only in the state of the coupling shaft 38 shown here, in other words only when the key 222 is fully inserted.

The recess 385 in the coupling shaft 38 is formed by grasping this shaft with a suitable tool and pushing it to the left against the action of the coupling spring 383 to force the coupling pin 381 out of the cylinder rotor 22 and to adjust the lock to the state of use. Used to freely rotate the cylinder rotor 180° to the right or left for assembly purposes.

After the joint groove 361 rotates half a turn, the joint shaft 38 engages with the joint pin 382°, and the joint shaft sleeve 36
is configured to rotate along with the joint shaft 38.

At the other end of the joint shaft 38, the joint shaft portion 39 is elastically connected to the joint shaft 38 by a joint spring 383.
The construction is such that it is movable parallel to the shaft axis within predetermined limits relative to the shaft axis.

That is, the side of the coupling shaft portion 39 facing the coupling shaft 38 has a hole 391 in which the coupling spring 383 is inserted.
and specially shaped end 384 of coupling shaft 38
is located.

A pin 392 is provided at the end to prevent the end 384 from being pushed out of the hole 391 by the coupling spring 383.

The coupling shaft part 39 is identical to the coupling shaft 38 (with two coupling pins 393, 394, which have exactly the same function as the coupling pins 381, 382).

When the state of the joint shaft portion 39 is compared with the joint shaft 38 described above, it is noticed that no key is inserted into the cylinder rotor 23.

This resilient connection between the coupling shaft 38 and the coupling shaft section 39 makes it possible, unlike conventional locks, to prevent locking even when the key 222 is fully inserted into the cylinder rotor 22. A key can be inserted into the cylinder rotor 23 to perform locking and unlocking functions.

Besides all the lock elements 10-39 mentioned above, still some other elements are the same (housed within the lock housing 10).

For example, there is a set screw 162, which is used for centering the grip 16 and is drilled in the grip with a centering hole 163 that cooperates with the set screw 162 so that the grip screw 161 can be easily inserted.

Another important component is the set segment 40 shown in FIG. 4, which is located behind the set screw 401 in FIG.
is laterally screwed into the bearing bushing 24, which is fixed to the lock housing jig by the cylinder sleeve screw 26, so that the set screw 401 does not move.

The set screw 401, in particular, prevents the hollow shaft 17, which is rigidly connected to the locking segment 40, and all other locking elements, which are rigidly connected to the hollow shaft and are rotatable relative to the lock housing 10.

Stop rotor 30.31 and joint shaft sleeve 36
The range of rotational movement in the clockwise or counterclockwise direction in FIG. 4 is limited.

In FIG. 4, a set screw 401 and a spring retaining screw 175 are fixedly connected to the hollow shaft 17.

A return spring 41 is tensioned between them, which keeps the hollow shaft 17 and the blocking rotor 30.31 firmly connected thereto, together with the joint shaft sleeve 36, in the position shown in FIG. In other words, on the side of the stopper segment 40, the side of the connecting pin 402 connecting the stopper segment 40 with the hollow shaft 17 is brought closer to the set screw 401. is working.

This state of all locking elements is a steady stationary state, i.e. the locking unit 50 or (Fig. C82) the locking par 501 has a spacing screw 502, a locking piston 503
This is because, together with the locking spring 504, it is elastically freely movable in the longitudinal direction.

A cover sleeve 43 is mounted over the bearing bush 25 to cover the return spring 41 and the stop segment 40.

As shown in FIG. 2, the above-mentioned parts 501--50
4, a locking sleeve 505 and a locking cover sheet 506 also belong to the locking unit 50.

All of these locking units 50 are located in two cutouts 105 in the lock housing 10, offset from the center but parallel to the lock housing axis, as shown in FIG.

Further, as is clear from FIG. 1, the locking unit is movable in the longitudinal direction of the lock, and this is done so that the position of the locking hole in the door plate 9 may be asymmetrical.

Furthermore, according to FIG. 2, the rear part of the locking sleeve 505 is open downwards, and the locking piston 503 has two circular segments 5031 and 5032.

The radius of the circular segment portion 5032 is the radius of the blocking segment 4
2, the blocking segment is rigidly connected to the joint shaft sleeve 36 and rotates as a unit.

When the coupling shaft 38 is turned by means of a key through either the coupling part 221 or 231, the coupling shaft sleeve 36 and the blocking element 42 fixed thereto.
It rotates as well.

Furthermore, as mentioned above, the coupling shaft sleeve 36 is constrained by the shape of the coupling grooves 361, 362, so that the coupling shaft sleeve 36 is
8 performs only a half rotation even when the rotation is complete, so that the blocking segment 42 rotates around the circular segment portion 50.
32 thereby locking the locking piston 503 and the locking par 501 connected to it by a spacing screw 502.

The door is then locked by rotating the door lock 222.

The other side locking par 501 keeps the grip 15 or 16 in the second position as long as the blocking segment 42 is in the position shown in FIG. 1 or FIG.
By turning it counterclockwise in the figure, it can be pulled into the locking sleeve 505.

This is due to the following operation.

Grips 15 and 16 are rigidly connected to hollow shaft 17, which rotates together with grip 15,16.

In the region of the cutout 105 the hollow shaft 17 is open at the top, and when the hollow shaft is rotated in the above-mentioned direction, the locking piston 503 is moved by the locking spring 50.
The circular segment portion 5031 is pushed into the locking sleeve 505 against the force of 4 and the circular segment portion 5031
7.

This movement of the locking piston 503 causes the locking member 501 to be partially drawn into the locking sleeve 505.

Door 9 can then be opened. The main advantage of the door lock according to the invention is that the direction of rotation of the grip 15.degree. 16 can be changed very easily.

Simply change the mounting of the locking segment 40 (FIG. 4) to the other side with respect to the set screw 401 of the hollow shaft 17, which can be easily rotated, change the engagement of the return spring 41, and set screw 37 (FIG. 1).

into the thread 176 of the hollow shaft 17.

Of course, the direction of insertion of the locking unit 50 into the cutout 105 must also be reversed.

However, the function of the door lock does not change at all due to this switching.

Furthermore, by inserting a spacing screw 502 between the locking bar 501 and the locking piston 503, the depth of penetration of the locking part 501 into the closing plate can be adjusted depending on the situation.

FIG. 5 shows a variation of the J door lock which is similar in construction to that shown in FIG.

The difference is that the cylinder rotor 22 has been replaced by a part 51 which serves as a closing head.

This closing head 51 is the same as the cylinder rotor 22.
It has a joint portion designated 11.

This joint part performs the same function as joint part 221 (FIG. 1), i.e. it rotates the closure head 51 onto the joint shaft 385 by the same mechanism as generally shown in FIG. It is possible to connect them.

However, the coupling shaft also has a positioning element 38
51, this element 4 has a positioning spring 3852
Resiliently joints shaft portion 385 in the longitudinal direction of the lock
3, the positioning element engages the joint shaft sleeve 36 instead of the joint pin 393 of FIG.

This configuration of the joint shaft portion 3853 makes it possible to open the lock by pushing the key into the cylinder head 51 without having to make one complete rotation of the closing head 51.

The positioning element 3851 slides into the coupling groove 362 of the coupling shaft sleeve 36 under the action of the positioning spring 3852 in the appropriate rotational position of the cylinder rotor 23, coupling piece 231, coupling shaft part 3853.

The rotation of the joint shaft sleeve 36 initiated by the closing head 51 can therefore be stopped by a key from the other side of the lock.

The advantage of this construction is that the door lock can be locked or unlocked from either side at any time, regardless of the rotational position of the opposing parts 51 and 23.

As shown, the closing head 51 has two different positions in the longitudinal direction of the lock.
It has two terminal states.

One of them is the state shown in the drawing, which corresponds to the state of the cylinder rotor 23 in FIG. 1, in which no key is inserted into the cylinder rotor.

In this state, the pin 52 of the cylinder sleeve 181 engages with the groove 512 of the closing head 51, and the closing head 51 and the cylinder sleeve 181 rotate as one.

However, since the cylinder sleeve 181 is non-rotatably connected to the lock housing 10 as described in connection with FIG. 1, the closing head 51 cannot rotate in this position.

This corresponds to the configuration shown in FIG. 1, in which the cylinder rotor 22 can only rotate when the key is inserted.

If, on the other hand, the closing head 51 is pressed in against the action of the closing head spring 513, the pin 52 will move out of the groove 512 and the closing head will be rotatably released.

As a result, when the closure head 51 is rotated, the coupling shaft 385 will also rotate with it.

In this manner, the lock of the present invention is locked with the closing head 51 assuming the function of the key 2220 in FIG.

Even in this door lock variant, if the closing head 51 is pressed in, the key 222 can be inserted into the cylinder rotor 23, ie the action of the coupling shaft 385 is the same as in FIG.

All other features of this structural variant, together with the function and construction of the other side parts, are as shown in FIG.

The variant of the invention according to FIG. 6 is a door lock that can be closed only from one side and is suitable for example for a nursery door.

This door lock has almost the same construction as the door lock according to FIG. 5 or FIG. 1, except that the joint shaft portion 39 and the cylinder rotor 23 are missing.

Also in this variant, neither the blocking sleeves 28, 29 nor the blocking sleeve springs 32 and 33 are required and therefore are not installed.

In FIG. 6 it is suggested that the blocking sleeve 42 can be fixed by means of a screw 421 to the joint shaft sleeve 365, which joint shaft sleeve is simplified compared to that according to FIGS. is firmly connected.

FIG. 7 also shows another variant of the invention, which is particularly suitable for toilet doors and which has a red-green display element 60 on the side opposite the closing head 51. This element is attached to an extension of the coupling shaft 387.

Otherwise this modification is similar to that according to FIG.

FIG. 8 shows a variant of the door lock according to the invention which is particularly suitable for installation on hotel room doors.

The structure is generally similar to that according to FIG.

The difference is that in the joint unit the hollow shaft is in two parts and that the locking part 501 (FIG. 2) is movable even in the locked configuration due to the absence of blocking segments.

In this embodiment, the hollow shaft 17 in FIG.
5 cannot be activated.

The separation position of hollow shirt N7/178 is indicated at 179.

The joint shaft 388 is almost the same as the joint shaft 38 in FIG. 1, but as shown in FIG. 9, unlike the one in FIG.
3 does not have.

The joint shaft 388 can, in an emergency, be turned by inserting a hexagonal head screw that fits into the hexagonal groove into the hexagonal groove through the keyhole of the cylinder rotor 238 and the hole 81 of the joint shaft portion 389, thereby opening the lock. Can be done.

The reason for providing such a mechanism is that in this modification, as mentioned above, there is no joint spring 383, and although the joint portion 389 can rotate relative to the joint shaft 388, it cannot move relative to the longitudinal direction. Therefore, when the key is inserted into the cylinder rotor 228, even if the key is inserted into the opposite cylinder rotor 238, the coupling shaft portion 389 cannot be coupled with the coupling sleeve. This is because it cannot be pushed in fully.

This variant of the invention furthermore has a ring 82 on which an indicator pin 821 is fixed, which indicates when the lock is locked, i.e. when the blocking sleeve 29 is moved outwardly (as described in connection with FIG. 1). When it slips, it becomes visible from the outside of the lock.

Furthermore, the cylinder rotor 228 has a safety element in the form of a pin, which pin is connected to the cylinder rotor 228 and has a stop 228.
The pin limits the range of key rotation when the key rotates approximately one revolution by striking 283.

The peculiarity of this embodiment is that the door can only be opened with a key from the left side of FIG. 8, and only if the lock is not locked from the right side.

Of course, other variations not mentioned here are also possible, but are included in the invention.

Similarly, it is also possible to change the structure of the elements of the lock or locking unit without changing the idea of the invention.

For example, the coupling shaft of Figure 5.6.7 may be rigidly connected to the coupling part of the closure head or to the closure head itself.

Furthermore, in the lock variant according to FIGS. 6 and 7, it is also possible to provide a hexagonal or square-shaped emergency release device on the top side of the joint shaft facing the closing head.

As can be seen from the above description, since the locking unit is a locking mechanism in its retracted position by means of a blocking segment, it is clear that the door lock according to the invention can also be used as a roll-drop lock for a swivel door. It is.

FIG. 10 shows a variant which is broadly similar to the variant according to FIG. 8, and corresponding parts are designated by the same reference numerals.

In this case, the indicator pin 8211 is connected directly to the left coupling shaft part 389, ie the inwardly bent inner end of the indicator pin fits into the bore of the coupling shaft part.

In this case the protruding display pin indicates that the key is on the right hand side, which also means that it should not be disturbed, for example in a hotel room.

However, as suggested in FIG. 10 (if the key is inserted on the right side, it cannot be opened from the left with the key).

Unlocking in case of emergency is possible with a hexagonal key as described in FIG.

The structure for emergency unlocking described above could also be applied to the lock according to Figure 5.6.7.
