Mounting structure for controlling operation of door lock handle and door lock of the mounting structure

Technical Field

The present invention relates to a mounting arrangement for the operation of a solenoid controlled handle in a door lock, in which the transmission of force from the operating axis of the handle or the like to a follower acting on the bolt of the door lock from either side of the door lock is arranged by means of a movable engagement member which receives guidance thereof by a solenoid arrangement; and to a door lock in which the above-described mounting structure is used.

Background

The control of the handle operation using the electromagnetic coil device in the door lock may be implemented in various ways according to the use. The mounting structure may be, for example, such that: i.e. when the solenoid is energized it allows or enables correct passage using the handle and thus the force transmission from the handle to the latch bolt is engaged. Alternatively, when the solenoid is de-energized, the solution may be reversed such that the mounting structure allows for proper passage using the handle. The method of operation of the mounting structure depends on whether the stresses are arranged to ensure correct passage or disengagement of the locking spaces or whether the stresses are arranged to ensure locking spaces such as these.

In practice, the mounting structure is generally such that: i.e. from the outside of the door, can always be opened with a key or the like operating the lock mechanism, and from the inside with a handle, knob or the like, whereby selective engagement of the handle operation simultaneously assumes operation of a two-piece or divided shaft. Depending on the location of the application, the mounting structure may also be such as: i.e. the door is provided with handles or the like on both sides, whereby the door can always be opened with the handle from one side of the door and from the other side only selectively depending on the situation.

Another patent application discloses a solution to the problem that: how the same basic parts to be mounted in the lock case are applied to both manipulation methods, so that the selection of the handle manipulation method can be achieved in a simple manner from outside the lock case without the need to open the lock case. However, the installation of such a door lock also involves making another basic choice, according to the above: on which side of the door and thus on which side of the lock case of the door lock, a handle operation needs to be provided. In this respect too, it is desirable to avoid the provision of two separate door lock boxes which are rotatable in different directions.

Disclosure of Invention

An object of the present invention is to solve the above-described problems and to provide a mounting structure with which a lock case can be improved in door mounting so that the lock case can be applied to a door regardless of a predetermined direction for door opening rotation. It is also an object to provide a mounting arrangement with which, if desired, the measures to be developed in the lock case can be carried out in as simple and easy a way as possible without opening the lock case.

The object of the invention can be achieved as more closely disclosed. According to the present invention, there is provided a mounting arrangement for the operation of a solenoid controlled handle in a door lock in which the transmission of force from an operating axis of a handle to a follower acting on a bolt of the door lock from either side of the door lock is arranged by means of a movable engagement member which receives guidance thereto from a solenoid arrangement, the follower being provided with two separate first and second twisting means mounted on the operating axis on different sides of the follower and rotatably supported on the follower and engageable by said engagement member with the follower into force transmitting connection, characterised in that: the operating axis is arranged so that a spindle of a handle mounted on the operating axis is normally directly positionable in force-transmitting connection with the driven member, the mounting arrangement comprising a coupling member arranged to be selectively mounted on the operating axis in a spindle opening of either of the first and second twisting devices to thereby prevent direct connection of a spindle of the handle with the driven member so that the spindle of the handle is in force-transmitting connection with said first and second twisting devices.

According to the invention, the mounting arrangement advantageously comprises a fitting arranged to be mounted in the spindle bore of any one of the twisting devices so as to prevent the spindle of the handle from being directly connected to the driven member, such that the handle spindle is in force-transmitting connection with the twisting device. So that a handle with a normal length spindle can be used in all situations.

In a preferred embodiment of the invention, the engagement member comprises two arms, each arm being engageable to cooperate with its own torsion device. In this case the engaging member can be moved normally under the control of the solenoid, but for changing the handle operation from one side of the door to the other, there is no need to move the engaging member.

In another embodiment of the invention, the joint comprises a projecting arm having a first mounting position in which the arm engages the first torsion device and a second mounting position in which the arm engages the second torsion device; whereby the engaging member is movable from a first mounting position to a second mounting position for changing the handle operation from one side of the door lock to the other.

The joint has the advantages that: rotatably journalled on the follower and arranged to be movable in the direction of the operating axis for effecting said change in the operation of the handle. For this purpose the driven member advantageously comprises a sleeve for journaling the engagement member. The follower may additionally contain a guide, such as a tab, that normally prevents movement of the engagement member from its first mounting position to its second mounting position. Accidental movement of the engaging member can thus be easily prevented.

The engagement element furthermore advantageously comprises a counter surface for an installation tool. If then the lock case of the door lock comprises an opening through which an installation tool can cooperate with said counter surface for said movement of the engaging member, said means for installation can be easily implemented when the lock case does not need to be opened.

The spindles of the first and second twisting devices are configured such that: i.e. they allow the adapter to be inserted into and removed from the twisting device without disassembling the twisting device.

The solenoid device comprises a solenoid, a shaft element arranged to be moved under the action of the solenoid against the force of a spring and to rotate a lever member arranged on the shaft element about a spindle to select whether the engagement member is in a position for transmission of a coupling force.

A second aspect of the present invention relates to a door lock to which the above-described mounting structure is advantageously adapted, and which comprises: a latch; a follower for moving the latch; the two ends of the operation axis can be provided with an operation device for operating the driven piece; whereby the transmission of force from either side of the door lock to the follower is arranged by a movable engagement member which receives guidance thereto from a solenoid device or the like. The driven member is provided with two separate twisting devices which are mounted on the operating axis on different sides of the driven member and are rotatably supported on the driven member, and which can be engaged in force-transmitting connection with the driven member by means of said engaging members. An operating device is arranged and mounted on the operating axis on one side of the lock and the follower, for example: a key, handle or the like operating the lock mechanism, the operating means acting directly on the follower through a spindle bore located in the follower. An operating device is arranged and mounted on the other side of the lock and the driven member on the operating axis, for example: a handle or the like, which operating means is arranged in force-transmitting connection with the driven member via a twisting device and said engaging member.

The option of providing force transmission through the twisting device is arranged by the application of a separate adapter which fits into the spindle bore of the selected twisting device such that it prevents the handle spindle from directly connecting with the driven member.

In the case of a coupling member comprising a projecting arm which is functionally connected at one time only to a twisting means, the option of providing force transmission by the twisting means is arranged by arranging said projecting arm of the coupling member on the desired side of the driven member.

The invention is described below, by way of example only, with reference to the accompanying drawings, in which:

Detailed Description

In the figures, the reference numeral 1 designates a lock case of a door lock with a cover, which is shown partly broken away in the figures. The lock case 1 is provided with a front plate 2, through which front plate 2 the bolt 12 of the lock can be moved. Furthermore, the lock case 1 is provided with an operating axis 3, on which operating axis 3a follower 4 is mounted rotatably supported, which follower 4 is shown in this embodiment to act on the bolt via a separate force transmission lever 5. Depending on the form of the lock, the follower may naturally be arranged to move the bolt of the lock also directly when required.

It is in fact possible to influence the follower 4 from both sides of the lock case. A key or the like for operating the lock mechanism, provided with a torque arm or a corresponding force transmitting element (not shown) acting directly on the follower 4, is mounted on the operating axis 3 on one side of the lock case, as is known. Alternatively, a handle or the like can be mounted, the spindles of which act directly on the driven member 4. On the other side of the lock case a handle, a knob or the like is mounted on the operating axis 3, while its spindle (see fig. 2) is independent on said force transmitting element of the lock mechanism or of the handle spindle, which handle is mounted on the other side of the lock, so that the above-mentioned handle operation can be controlled independently accordingly. The force transmission required for the handle operation is arranged by means of a joint 6, 6 ', the joint 6, 6' having two selectable operating positions: a force transmitting engagement position in which the latch of the lock is movable by the handle; and a force transmitting disengagement position in which the latch of the lock is correspondingly not accessible by the handle.

The control of the handle operation is produced by means of a device comprising a solenoid 7 which moves a shaft element 9 against the force of a spring 8. A lever element 10 is arranged on the shaft element 9, the lever element 10 being rotatable about a spindle 11 and by means of the lever element 10 it being possible to select whether the engagement elements 6, 6' are in a position in which a connecting force is transmitted.

The follower structure of fig. 2 is as follows. The follower 4 is provided with a spindle bore 4a, in which the follower 4 is arranged at the position of the operating axis 3. Since the twist arms associated with the key operation of the lock or with the handle spindle to be mounted on the respective side of the lock actually extend to the spindle bore 4a (not shown), the twist arms can always be applied to directly operate the follower 4. The driven member 4 further comprises a sleeve-like element 4b, and the coupling member 6 is rotatably journalled on the sleeve-like element 4 b. The engaging member 6 comprises two projecting arms 6a and 6b which are located on either side of a projection 4c provided on the follower. The projection 4c prevents the engaging piece 6 from moving in the direction of the operation axis 3.

On different sides of the driven member 4, there are rotatably journalled twisting devices 13 and 14, the twisting devices 13 and 14 comprising spindle bores 13a and 14a and corresponding surfaces 13b and 14b of the projecting arms 6a and 6b of the coupling member 6. The entire follower structure is rotatably journalled on the lock case 1 by means of the bearing element 15. The follower structure also includes an adapter 16, with the adapter 16 providing handle manipulation options such that the handle spindle 17 extends into the spindle bore 13a or otherwise into the spindle bore 14a but not into the actual spindle bore 4a of the follower. The force transmission required for the handle operation can thus be engaged or disengaged under the control of the solenoid 7, on the side of the door where in each case the adapter 16 is mounted in the spindle bores of the twisting devices 13 and 14 (see fig. 3a and 3 b). Since the adapter 16 is dimensioned to be inserted into the spindle bores of the twisting devices 13 and 14, it can be removed if necessary to be mounted on the other side of the lock without opening the lock case 1.

In another embodiment, shown in fig. 4, the joint 6 'comprises only one protruding arm 6' a, the protruding arm 6 'a being movable in the axial direction of the sleeve-like element 4b, so that the protruding arm 6' a can be optionally mounted on either side of the cam 4c of the follower. To arrange the displacement operation, the engaging member comprises a corresponding surface 6' c of a suitable tool, such as a screwdriver. The other parts of the embodiment of fig. 4 are similar to those shown in fig. 2, 3a and 3 b. Thus, when someone wishes to change the operation of the solenoid controlled handle from one side of the door to the other, it is first necessary to move the engaging member 6 'so that its projecting arm 6' a is disposed on the other side of the projection 4c and additionally to have the engaging member 16 moved to the other side of the lock.

The means (method) of mounting the joint 6' in connection with the embodiment of fig. 4 are illustrated with fig. 5a-5d and fig. 6-8. In the starting condition of fig. 1 and 5a, the coupling element 6 'with its projecting arm 6' a is in contact with a corresponding surface 13b of the twisting device 13, the twisting device 13 being acted upon by the lever member 10, whereby a handle (not shown) mounted on the operating axis 3 is in force-transmitting connection with the driven element 4. When the lock case is mounted on the door, the following mounting measures are implemented in case it is found that the handle operation will be on the wrong side of the door in this position of the engaging member 6'.

The follower 4 is rotated from either side of the lock case to the open position of the latch according to figure 6. As a result of which the corresponding surface 6' c of the engagement member is located at the position of the opening 1a in the cover of the lock case 1. The engagement member 6 ' is rotated by applying the counter surface 6 ' c through the opening 1a using a suitable tool, as shown in fig. 5b and 7, so that this can be followed by further pressing the engagement member 6 ' along the sleeve-like element 4b beyond the position of the projection 4c to fig. 5 c. In this position the tool can be used to turn the engaging member 6' further into the position of fig. 5d and 8. After this, the driven member 4 is rotated back into the position of fig. 1, whereby the engaging member 6' can again be selectively arranged by means of the electromagnetic coil 7, via the corresponding surface 14b of the twisting device 14, into force-transmitting connection with the driven member 4. By these measures and also by moving the adapter 16 from one side of the lock to the other as described above, the handle operation can be changed from one side of the lock case to the other, as required by the lock installation situation. Thus, according to the embodiment of fig. 2, under the control of the solenoid, the two torsion devices 13 and 14 can always be guided by the arms 6a and 6b of the joint 6: in force-transmitting connection with the follower, whereby the position of the adapter 16 determines on which side of the lock the handle operation can be controlled with the solenoid in the described manner. The embodiment of fig. 2 can in principle be applied without the adapter 16, so that the handle with the spindle is shorter than is normally mounted on the operating axis 3, so that it normally extends only to the spindle bore of the twisting device but not to the spindle bore of the driven member.

The invention is not limited to the embodiments shown but several modifications are readily available within the scope of the appended claims.
