Description

MAGNE T BOLT LOCK AND KI T

The present invention relates to a magnetic latch lock. Furthermore, the present invention relates to a kit comprising a magnetic latch lock according to the present invention with a magnetic strike plate.

For closing of a door in a casing and alternatively a window in a casing, it is known to use a mortise lock in a door or a rim lock on a door that are provided with a slanted latch and or a bolt latch. Traditionally, the bolt latch is a cuboid member that slides into the casing, strike bowl or strike plate from the lock. On the other hand, a slanted latch relative to a bolt latch is provided with a slanted side at the inside of the lock such that the door can be pushed shut and the slanted latch slides away relative to the frame by means of the slanted side. This functioning of the slanted latch is associated with sound, for the purpose of which a so- called whisper slanted latch has been developed with a plastic inlay for preventing such a noise.

In order to provide an alternative solution, the magnetic latch lock with the magnetic latch is developed. A magnetic latch substantially has the external appearance of a latch bolt but it is controlled with magnetic forces with

application of magnets arranged in the latch. Such a magnetic lock foregoes the necessity of an adjustment to the casing order to allow functioning of the slanting latch by means of a guiding lip guiding the slanting latch.

In order to provide a further development of the above developments, the present invention provides a magnetic latch lock for being mortised into or being mounted on a door closing and opening of the casing, the magnetic latch lock comprising :

- a holding member comprising at least one holding element with preferably a closing member, the holding member and the closing member further preferably forming a housing, - a faceplate that is directed towards the casing in a closed state of the door,

- a magnetic latch, comprising at least one magnetic element for providing a bias to the magnetic latch in at least a position or a trajectory of motion thereof,

- a tumbler for transferring a movement of a doorknob to the magnetic latch by means of a latch actuator,

- the faceplate comprising a through feed opening for feeding through and or keeping arranged therein of the

magnetic latch,

- wherein at least one of the at least one holding element functions as a magnetic latch guiding element when moving between an open position and a closed position,

- wherein the magnetic latch is retainable in the open position by a lock biasing force relative to the magnetic latch lock and wherein the magnetic latch is retainable in the closed position by a strike plate biasing force relative to the casing or a therein arranged strike plate, such as a magnetic strike plate.

An advantage of a magnetic latch lock according to the present invention is that it is manufacture able in a

straightforward manner and as such provides a practical and advantageous solution. Because the magnetic latch in the function of replacing of a slanted latch is being retained in the open position by the lock, the door closes the easily and bumping against the mostly present slanted latch is prevented. A magnetic striking plate causes the magnetic latch to move out of the lock. Because the magnetic striking plate is arranged in the casing, this does only happens after the door has been moved to the closed position relative to the casing.

According to a first preferred embodiment according to the present invention, the magnetic latch guiding element also functions as a tumbler stop. Because of this, the

manufacturability is advantageously further improved as merely one holding element is required for these both functions. The arrangement relative to this single holding element is thus further simplified.

A further simplification of the manufacturability is realized with application of a further preferred embodiment in which the tumbler is provided with at least a stop element for stopping against the magnetic latch guiding element. With this, it is realized in a straightforward manner that the tumbler is functionally limited with regards to move ability for the purpose of the function of activating the magnetic latch by means of the latch actuator. Advantageously, it is provided that the tumbler has two stop elements in between which the carrier element also functioning as latch guiding element during use is arranged. With this, the tumbler can move between these both stops and move ability of the tumbler is determined.

For the purpose of operating the magnetic latch,

according to a further preferred embodiment, the magnetic latch lock comprises a gripping element for moving of the magnetic latch from the closed position to the open position by means of gripping by the tumbler, wherein further

preferably the gripping element extends over a part of the thickness of the magnetic latch. With this, it is realized that about one rotate able tumbler, both the gripping element as the stops are personable and are functional for the

function those have as described.

Further preferably, the gripping element is arranged at the side of the holding member or at the side of the closing member. With this, it is determined that scene preferred the height of the tumbler along the heart line thereof, the underside comprises the stop or stops and the topside

Alternatively, it is provided that the at least one stop of the tumbler is present and the gripping element is a loose part couple able with the tumbler. With this, the at least one stop element is preferably arranged in the magnetic latch lock at the opposing side of the tumbler relative to the gripping element. With this, a practical manufacturability is realized wherein during rotation of the tumbler, both the stop element and the

gripping element parallel relative to one another in the rotation direction can function with the holding element respectively the magnetic latch.

According to a further preferred embodiment according to the present invention, the magnetic latch lock comprises a locking assembly for locking of the magnetic latch lock with the magnetic latch in the closed position. By means of such a locking assembly, besides holding the door closed by means of the magnetic latch lock, the door can also be kept locked. The lock is being locked by means of the locking assembly because of which the magnetic latch besides functioning as a slanted ledge, functions as a latch bolt. With this, the locking assembly provides for locking of the magnetic latch.

Further preferably, the locking assembly coacts with the magnetic latch and/or the tumbler, preferably a blocking member thereof, the magnetic latch and/or the tumbler. By this coaction, the magnetic latch is blocked in the locked state, which means that it extends out of the lock and when the lock in the door is rotated thus extending from the door into the casing or into the striking plates thereof.

According to a more detailed preferred embodiments thereof, the locking assembly comprises a movable, preferably linearly movable or slidable, looking element for locking of the magnetic latch lock in coaction with the magnetic latch and or the tumbler, preferably a blocking member thereof. With this, the locking element shifts to a position in which it is engaging with the magnetic latch and or the tumbler.

Further preferably, the locking element locks the blocking member of the tumbler, wherein further preferably the locking element engages along one, 2 or 3 sides with the blocking member. By means of these features, a high degree of coaction and a high degree of reliability of the locking is realized.

Further preferably, in the magnetic latch lock, the tumbler is provided with a biasing engaging member for

engaging with a biasing member, such as a spring, wherein preferably the biasing engaging member also fulfills the function of blocking member. With this, this realized that the tumbler automatically returns in the starting position after operating thereof. Alternatively, this is possible by a biasing provision in a shield or rosettes at the outside of the door, wherein the biasing provision for operating of the lock with application of these features does not need to be provided.

Further preferably, a surface or edge of the locking element functions as a stop for the tumbler or the blocking member thereof for limiting of deflection by the biasing force exerted thereon by the biasing member. With this, a further part for the purpose of the provision of a stop is prevented.

For the purpose of a reliable move ability, the locking element is held by at least two holding elements that

preferably function as latching element guiding element. With this, it is realized that a locking element is movable along a predetermined path relative to the holding member.

Further preferably, there is provided a locking actuator for moving of the locking element, which locking actuator is preferably embodied as a further tumbler or which actuator is insertable as a lock cylinder in an opening thereto arranged in the holding member and or closing member.

preferred embodiment.

A first preferred embodiment (fig. 1-5) according to the present invention relates to a magnetic lock 10 with a magnetic latch 31, that is part of a locking assembly 20 operating the latch. A housing is comprised of a holding member formed by a first shell part 11 with a closing member with a second shell part 11' . At the holding member a number of holding elements 12, 13, 14, 15, 16, 17 are arranged with respective functional openings 12', 13', 14', 15', 16', 17' therefore. These holding elements have several functions. The holding element 12 serves the purpose of guiding of the magnetic latch 31 along the inside channel 36 thereof. With this, it is possible that the latch moves from the open position to the closed position. The magnetic latch 35 comprises two magnets 9 in the inside for the purpose of providing the bias to the magnetic latch. The housing has to openings 18, 18' directly recognizable to the skilled person for letting through fastenings of a rosette or shield of door mountings .

The front side of the housing is closed by means of a faceplate 39 provided with a passage opening 38 for passing through of the magnetic latch 35. Furthermore, the faceplate has two openings 37 for the purpose of fastening with two screws at the casing side of the door of the magnetic lock after insertion thereof in the mortise present in the door.

The faceplate functions in the open condition in

cooperation with the magnets for providing of a bias to the magnetic latch such that the magnetic latch remains in the open condition while the door is open. To this end, the magnet has a bias with metal of the lock the moment the magnetic latch is pulled into the lock by means of the tumbler 41 that can rotate in the direction of the arrow C. For the purpose of transitioning the lock to the closed condition, it merely needs to be moved to the location of a magnetic striking plate with a higher magnetic bias force than the metal of the lock. Under the influence of this magnetic attraction force, the magnetic latch moves outward such that it transfers towards the closed condition. Herewith, the magnetic latch is guided by means of the holding element 12 in the channel 30 of the magnetic latch.

For the purpose of this described movement and operation, the magnetic latch is provided with a surface 32 at the

underside with which this is pulled into the lock by means of the tumbler 41, preferably the latch actuator 42 thereof. This latch actuator 42 engages with the surface when the latch is in the closed position and therewith pulls the latch to the open position. The latch actuator moves within the

circumscribed periphery of the latch within curved surface 33. The latch moves outwardly toward the stop 34 thereof. The tumbler 41 is arranged in the openings 21, 21' of the respective holding member and closing elements. For the purpose of maintaining the tumbler ready to operate, it has two cams 43, 44 between which the holding element 12 is being arranged. About a holding member 13, the biasing spring 29 that maintains the locking member under downward bias, is arranged The purpose of this is that the magnetic latch can always move from the open position to the closed position in case it reaches the location of the striking plate.

The tumbler 41 furthermore has a blocking member 45 at the underside thereof. The blocking member 45 is provided with a flat underside 48, a front side 47 and a top side 46. The sides respectively have contact with the surfaces 58, 57, 56 of the locking element 50 of the locking assembly for the respectively. The contact between the surfaces 48, 58 supports the function of the cam 43 in case of unwanted rotating away of the tumbler, in other words, the locking element retains the tumbler upwardly.

The blocking of the tumbler serves the purpose of keeping the magnetic lock in the locked position. The magnetic latch can only be opened in case the tumbler can move the latch from the closed position to the open position. In case the locking element 50 locks the blocking member, the latch cannot be moved from the closed position to the open position and the door is closed off or locked.

To this end, the locking element 50 is movable in the direction of the arrow B from a free position to the closed position. This movement is actuated by means of a second tumbler 51 with a tumbler arm 52. During movement, this tumbler arm 52 pushes from the free position toward the locked position against wall part 55 of the locking element 50. In the opposite direction towards the free position, this tumbler arm 52 pushes against the wall 54 of the locking element 50. A spring 28 provides a downward spring bias to the tumbler arm 52 such that this needs to overcome a discernible resistance during rotation of the right position to a left position and vice versa. To this end, this spring 28 has a downward bend 27 for increasing and/or pronouncing of this downward spring bias that is to be overcome.

The locking element 50 is preferably formed from a plate element 55 manufactured from a metal plate with bent supports 59 and the glide plate 53 fastened thereto made from

preferably steel or copper or an alloy such as brass.

The second preferred embodiment (Fig. 6-10) is

substantially similarly embodied as the first preferred embodiment. A first difference is that the upward tumbler 41 is built with the tumbler comprising the cams, in which the actuator for the magnetic latch is embodied as a separate substantially ring-shaped part that by means of a by cams of the tumbler 41 limited recess which can move relative to the tumbler about substantially the rotation angle of the tumbler, as determined by the cams 43, 44. A second difference is that the spring 28 is replaced by a simple spring 28' which is mounted in a locking element hereto adjusted. The locking element hereto has mounting slots 61, 62 for arranging therein of this spring. Next to these two described spring variance, such as for the locking element, further variants are

applicable within the understanding of the present skilled person. Furthermore, the locking element is hereto as a whole embodied from a plastic material. To this end, the steel part 50 is replaced with a plastic part.

A third preferred embodiment (fig. 11-15) relates to a preferred embodiment that is operable by means of a lock cylinder, in this example a euro cylinder. Placement means for placement of the lock cylinder comprise a passage opening 91 in the holding member with a respective opening 91' (not shown) in the closing member. Also this preferred embodiment has a slidable locking element 50 that is slidable by engagement of a cylindercam against the sides of a recess at the underside thereof.

The locking element has an extending pen 80 with a double function. A first function thereof is with a round part 81 thereof engaging with an about a rotation eye 76 relative to holding member 75 pivotably arranged positioning lever 70 with two positioning positions 71, 72 defined therein. A second function thereof is the holding of an actuation member 83 by means of an opening 84 thereof for vertically movably

arranging of the actuation member 83 relative to this pen 80, especially a square end part 82 thereof.

The locking element 50 is fixed in an open or closed position by means of the positioning lever 70 while during pivoting of this lever a horizontal sliding of the locking element 50 is possible. Because of this, it is possible to move the locking element by means of the cylinder between the open and closed position while without the direct actuation by the cam of the cylinder, the locking element remains in these respective positions. The lever is arranged held under

downwardly directed bias to the holding member 17 by means of a spring 77.

In the actuation of the cam of the cylinder, the

actuation member 83 pushes a substantially L-shaped magnetic lock actuation member upwardly such that the magnetic latch is urged sideways. To this end, the magnetic latch has a vertical channel formed by walls 93, 94 for guiding there through of the substantially L-shaped magnetic latch actuation member.

It is advantageous that of a lock according to the present invention the magnetic latch can be moved in this way from the closed position to the open position while the knob is still in the blocked position by means of the locking element. Because of this, by means of the key, both the knob can be blocked as the magnetic latch opened. An aspect according to the present invention therefore relates to a magnetic latch lock in which the magnetic latch may be operated by the cylinder directly, preferably also when the knob is still in the locked position.

In the embodiment according to fig. 16, a variant of the embodiment according to fig. 15 is shown. An integrated part 40' is formed with therein the openings for providing the pen 75 and the edits been 75'. The pen 75' provides relative to the previous embodiment a fortification and/or stabilization of the sideward movement relative to these pens. For the purpose of guiding of the actuation member 83, in this

embodiment advantageously relative to manufacturing two pens 81' are provided.

Also a preferred embodiment is provided (fig. 17) for operating of the magnetic latch lock by means of a bit key. This embodiment provides as an advantage that it can be used with this advantageous key type and in doors equipped for this. Also, application is provided in a new door in case of a key plan or lock already being present in a building or house. Operation of this variant is furthermore within the

understanding of the skilled person similarly to that of the cylinder variant.

An aspect according to the present invention relates to a magnetic latch lock in which actuation of the magnetic latch is performed by means of the cylinder by means of an actuation member that is arranged at the locking element or arranged in the locking arrangement.
