Description

The present invention relates generally to mortise locks and, in particular, to a mortise lock with a plurality of locking elements actuated by a key or door handle.

Background of the invention

Mortise locks are well known and are installed in recesses on the edge of the door, while they have latches or bolts that can enter and exit the recesses (i.e. push and retract) in the door jamb or frame. The bolts can be operated by a doorknob or cylinder lock.

A set of mortise locks are used to push and pull the locking bolts running vertically up and down after being installed in the door. Usually the space available for installing the mortise lock is limited in width. This places restrictions on the internal mechanical design of the mortise lock. As a result, as is known in the art, it is not possible to use common clutch elements of a door handle or a lock cylinder with upper and lower locking bolts. Instead, separate clutch elements are used to engage the door handle or lock cylinder with the upper and lower locking bolts. Clutch elements usually have a small thickness in order not to create mutual interference and to meet the requirements of a limited space.

Detailed description of embodiments

Consider FIG. 1, in which is illustrated a mortise lock 10 constructed and operating in accordance with a preferred embodiment of the present invention.

The mortise lock 10 may include a housing 12 in which a locking device is inserted, actuated by a mechanical cylinder 14 or a handle (not shown) that meshes with (usually, but not necessarily square), aperture 16 of the pusher axis 18 of the transom. Mortise lock 10 is preferably a multi-point lock, i.e. has many locking bolts and / or latches. Although any number of locking bolts and / or latches can be used in the present invention, in the illustrated embodiment, the mortise lock 10 has a latch 20 and a rectangular or locking bolt 22 protruding behind the front panel 24. Because, as described below, the locking bolt 22 serves as a locking element of the clutch, hereinafter also referred to as a locking element 22 of the clutch.

In addition, in the illustrated embodiment, two locking bolts 26 and 28 (also referred to as locking elements) are shown capable of moving in a vertical direction along the vertical door. Elements 20, 22, 26 and 28 are able to engage in various locking devices installed in the door and used for locking the door, and such devices are well known in the art, so the person skilled in the art does not need their further description.

In the locked position shown in FIG. 1, the locking bolt 22 cannot be pressed into the housing 12 (shown on the right of FIG. 1), since the inner edge 30 (the right side of the locking bolt 22 in FIG. 1) is adjacent to the protrusion 32 of the friction disk 34. The friction disk 34 has a slot 36 the pin 38 is included. The friction disk 34 is displaced by a bias device 40 (for example, a coil spring) capable of resisting the movement of the friction disk 34 upwards, as shown in FIG. 1. When the corresponding key (not shown) is inserted into the keyhole of the lock cylinder 14 and the key is turned in the glass of the lock cylinder 14, the cam 42 of the lock cylinder 14 is rotated. The cam 42 hits the lower part of the friction disk 34 and moves the friction disk upwards (as shown in FIG. 1), overcoming the force of the displacement device 40, due to which the protrusion is shifted away from the clutch locking element 22. Upon further rotation of the cup, the cam 42 engages with the recess 44 in the clutch locking element 22 and allows the locking clutch element 22 to enter the inside of the housing 12 into the unlocked position.

The locking bolts 26 and 28 may be connected to the locking element 22 of the clutch, for example, pins 46, which are included in the individual channels 48 in the locking element 22 of the clutch. As shown in FIG. 2 and 3, the clutch locking element 22 has a first surface 22 A facing the room and a second surface 22 B facing the opposite. The channels 48 overlap, at least partially, and are located on the first and second surfaces 22A and 22B. Due to this, the channels 48 do not interfere with each other, and each of them can actuate its own locking bolt (26 or 28), thereby saving space. It should be noted that each channel 48 may be made deaf, i.e. not pass through to the other surface of the clutch locking element 22.

As shown in FIG. 2 and 3, the design of the clutch locking element 22 includes a plurality of plates bonded with rivets or by welding or by any other appropriate method. Alternatively, the invention is not limited to this design, and the locking element 22 of the clutch can be made in the form of a solid structure (for example, by machining, forging, casting or powder metallurgy). As the locking element 22 of the clutch gradually enters inside the housing 12 to the unlocked position (to the right, as shown in Fig. 1), the locking bolts 26 and 28 gradually enter the housing 12 under the action of pins 46 moving inside the channels 48. Depending from the use of the locking element 22 of the clutch may enter into the housing 12 as a result of one rotation of the lock cylinder 14 or several rotations of the lock cylinder 14. As shown in FIG. 2 and 3, the clutch locking element 22 may have several recesses 44, and with each turn of the lock cylinder 14, the cam 42 engages with another recess 44, gradually moving the clutch locking element 22 further into the housing 12. Similarly, the clutch locking element 22 may have recesses 50 for successive engagement with the protrusion 32 at each turn of the lock cylinder 14 and stop moving the clutch locking element 22. Moving the clutch locking element 22 in a horizontal direction, as shown in FIG. 1 may be limited by the pin 52, which is inserted into the groove 54 in the clutch locking element 22.

As shown in FIG. 3, the clutch locking element 22 may be provided with anti-burglary elements 56 including, without limitation, hardened pins entering the recesses or holes 58 in the plates of the clutch locking element 22. Anti-burglar elements 56 make it difficult to saw or otherwise attempt to open the clutch locking element 22 for unauthorized access to the room. Due to the presence of a plurality of plates at the clutch locking element 22, the formation of recesses or holes 58 and the installation of the anti-burglary element 56 are facilitated and the cost of manufacture and installation is reduced.

As shown in FIG. 2, the clutch locking element 22 has a first portion 23 protruding beyond the lock body 12, and a second portion 25 not protruding beyond the lock body 12. Unlike the castles known from the prior art, in which the thickness of the first section is significantly greater than the thickness of the second section, in the present invention, the thickness of the first section 23 is no more than twice the thickness of the second section 25. For example, the thickness of the first section 23 may be approximately equal to the thickness the second section 25. Due to this, it is possible to significantly improve the security of the locking element 22 of the clutch from breaking.

Additionally, consider FIG. 4. The mortise lock 10 may include a clutch member 60 of a lock cylinder and a bolt ejector, which may be mounted on a pivot bearing 62, while its rotation may be limited by a biasing device 64 (for example, a coil spring). The rectilinear movement of the clutch cylinder locking member 60 and the bolt ejector may be limited by a pin 66 that fits into a slot 68 in the clutch member 60 of the lock cylinder and the bolt ejector. Thus, the clutch element 60 of the cylinder of the lock and the ejector of the bolt is able to carry out a straight and rotational movement. Located at the lower end of the element of the clutch cylinder 60 of the castle and the ejector bolt protrusion 70 may engage with the cam 42 (as described below).

In the embodiment shown in FIG. At the 4 position, the lock cylinder 14 is rotated in such a way that the vertical locking elements 26 and 28 (element 28 is not shown in FIG. 4) are partially retracted. The locking element 26 has not yet come into contact with the element 60 of the clutch cylinder lock and pusher bolt.

Consider FIG. 5. The cylinder 14 of the lock is more strongly rotated to a position in which the locking element 26 is even more strongly retracted, while the locking element 26 came into contact with the clutch element of the cylinder of the lock and the bolt ejector and began to turn it.

Consider FIG. 6. The cylinder 14 of the lock is rotated even more strongly into a position in which the locking element 26 is even more strongly retracted, while the locking element 26 has turned the clutch element 60 of the lock cylinder and the bolt ejector into position for actuating the ejector 18 of the bolt. In this position, the clutch element 60 of the lock cylinder and the bolt ejector extends generally parallel to the locking element 26.

Consider FIG. 7. The cylinder 14 of the lock is rotated one more turn to actuate the ejector 18 bolts through the element 60 of the clutch cylinder lock and ejector bolt. In particular, in the illustrated non-limiting embodiment of the invention, the cam 42 hits the protrusion 70 and pushes the clutch member 60 of the lock cylinder and the bolt ejector in the direction of the striker 72 of the bolt ejector 18.

As a result of this, the pusher 18 of the bolts rotates and the latch 20 retracts inside the housing 12.

The person skilled in the art will appreciate that the present invention is not limited to what is specifically illustrated and described above. The scope of the present invention includes combinations and sub-combinations of the features described above, as well as their improvements and variants that are unknown from the prior art, which could be offered by a person skilled in the art after reading the above description.
