Description

Magnetic lock, magnetic keys and combination thereof

The present application relates to a magnetic lock, a magnetic key and a mating combination of a magnetic lock and a magnetic key as shown in the EP1 355 550.

The present application provides a contrast structurally simplified and easy-to-use magnetic lock.

The application relates to a magnetic lock with at least one bolt which can be configured as a driver with a latch plate. The latch has a first magnet and that is switched between a locking position and an unlocking position and is movable so that a receiving opening closes in the locking position of the bolt for a particular designed as a shaft locking element at least partially or completely. In addition, in the magnetic lock, a second magnet is provided, wherein the first magnet and the second magnet exerting a force on each other. Here, preferably permanent magnets are used, but there are also magnetic materials as a magnet used if obtained with this same effect. Advantageously, the latch is pulled into the locking position together with the magnet due to this force. This results in a space-saving and safe design of the magnetic lock. In this case, not only comprises a dynamic drawing, but also a static hold of the latch or the driver.

Instead of attracting magnets themselves, they can also be arranged so that they repel each other. But then, in many cases, a slightly larger space.

In a further embodiment, a first latch and a second latch, that is also catches are provided, each with a locking bar plate in the magnetic lock, wherein the first latch comprises at least one first magnet and said second bar has the second magnet. The first bolt and the second bolt are switched between a locking position and an unlocking position and forth, so that in the locking position of the first latch and the second latch or the latches plates a receiving opening for the locking element or for the shaft at least partially or entirely close. This version is particularly safe and reliable in operation, because an opening and a closing of the magnetic lock with particularly small footprint is possible. With two bolts or carriers they can in fact linear back and forth between the locking position and an unlocking position and are formed fro while in the practice of this is often designed to be rotatable with a hinge with only a single bar or follower. This rotatable arrangement must then be carried out so that the receiving opening is completely possible released for a locking element in the open position of the lock, if a reliable function is to be ensured. In addition, a locking of the locking plates is made possible on the full surface of the groove of a bolt element or a socket.

Advantageously, run through the first magnet and the second magnet of the first driver and the second driver in the locking position. There are then, although additional spring elements or rubber elements possible, but these are not essential for a good seal. The first latch may also have two first magnets, thereby, while the second latch has two second magnets, respectively, a first magnet and a second magnet exerting a force on each other. This promotes a reliable operation of the magnetic lock.

The latches or catches can rotate freely in the magnetic lock, or they may be saved as a bridge in the magnetic lock and by a latching contour as driver contour or a contour in the carrier against rotation relative to the magnetic lock by a lock contour, for example in a mold when the lock contour accordingly engages the latching contour. The application provides an even conical recess in one embodiment in an upper part. In a lower part of a tilting groove is provided, wherein the latches are received in the tilting groove when the bars are for example added by an external force in the recess are moved relatively against the conical recess. Characterized a manipulation of the magnetic lock is prevented by counteracting the tilting groove an opening of the latch.

The latch may comprise a catch, which are made of a non-magnetic material so that one can be sure that only attract the magnets, and not the driver. This increases the reliability of the

Magnetic lock and prevents opening about a strong magnet from the outside.

The latch may include a latch plate having the metal. In connection with a driver is needed then restore only the driver of a lightweight material, while the receiving opening closing latch plate, for example, is made of solid steel.

The application also includes a lock assembly with such a magnetic latch, and a locking element or base of a conical shaped socket head, a revolving pedestal groove below the head and base having a base shaft below the rotating pedestal groove. engages the latch or the latch or engage the circumferential pedestal groove in the locking position.

To open the lock, a magnetic key is provided with at least two key magnets are arranged in a plane so that is a north pole of a magnet key facing up and a North pole of another magnet key down. This feature arises from the requirement that the key magnets located between the

so that the follower is pulled to the open position to overcome closed magnet acting force. In a more general form, the key magnets are arranged next to one another, so that is a north pole of a magnet key in one direction and shows a north pole of a magnet other key substantially in the opposite direction. Thus, other configurations are conceivable to not directly match the terms "above" and "disposed in a plane", "down", as well.

One can also provide for four key magnets which are arranged in a plane around a central point in such a way so that when the key magnets lie opposite each other relative to the center, in each case the same pole facing upward. This is particularly safe because one such trained driver can not or very difficult to open by an external, not correspondingly complex poled magnet key. Only a properly executed magnetic key opens this lock or catch.

If the key magnets are rotatably arranged on a plate about an axis of rotation, then by aligning is favored when opened.

On a projection on the underside of the magnetic key projections or steps can be provided, which engage in recesses in the

Top side of an upper part of the magnetic lock are provided. This promotes a focus on placing the magnetic key on a magnetic lock.

Finally, the application also includes a combination of such a magnetic key and such a magnetic lock, with one

Key magnet has in the unlocked position, respectively a horizontal offset from an adjacent magnet lock so that the key magnets are further apart than the lock magnets, then there is a reliable opening of the lock. The same advantage is obtained when a respective key magnet in the unlocked position each have a vertical offset relative to an adjacent magnet lock.

Figure 8 shows a side view corresponding to the magnetic lock 20 of Figures 4 and 5, in the unlocking position together with the magnet key 90 of Figure 7 in a cross-sectional view. The magnetic latch 20 is positioned directly below the magnet key 90 so that it is received in the edge 98th The markings 106, 108, 110, 112 to the magnet key 90 are provided to illustrate matching the marks 72, 74, 76, 78 on the magnetic lock 20th Only the lower two round magnets 46, 50 of the magnetic lock 20 are visible in FIG. 8 Figure 8 continues to make clear that the round magnets 100, 102 of the magnetic key 90 in the unlocked position are further apart than the round magnets 46, 50 of the magnetic lock 20. This ensures that the Magnetmitnehmer 36 are always securely tightened in the open position. Through the opposite polarity of the opposite sides of the magnets 100, the magnets 46 and 102, 50, attractive forces act between the magnets 100, 46 and between the magnets 102, 50. Thereby, the slide freely arranged Magnetmitnehmer 36, pulled apart 38th The Magnetmitnehmer 36, 38 thus move away from the base 22, so that the locking plates 53, 55 of the Magnetmitnehmer 36, 38 is also moved away from each other and are moved out of the revolving pedestal groove 42 of the base 22nd When the locking plates 53, 55 are moved out of the revolving pedestal groove 42, the socket can be extracted 22 from the opening 26 of the housing 24th

The magnetic lock 20 provides a simple locking device for coupling and uncoupling of the base 22 to the housing 24 and the lower part 32. The magnetic lock 20 has very few components on. Therefore, the magnetic lock 20 and the magnetic key 90 can be easily designed and manufactured.

The requirements to the outer shape and the internal coupling of the magnetic lock 20 are typically in the Hunderstelmillimeter- tolerance range. These tolerances can be met by inexpensive injection moldings. The cost for the series production of the magnetic lock in large quantities can therefore be kept low. The magnetic lock 20 does not require expensive components. For example, the round magnets 44, 46, 48, 50 are formed in the magnetic key 20 as rare earth ferrite magnets. The rotary magnets 44, 46, 48, 50 in the housing 24 of the magnetic lock also ferrite or alnico magnets may be, which are also cost effective. The upper part 25, the lower part 32, which Magnetmitnehmer 36, 38 and also the socket 22 may be manufactured inexpensively by typical injection molding of thermoplastic materials such as polystyrene, ABS, or acrylonitrile-butadiene-styrene, polyamide, polypropylene, polyethylene and polyvinyl chloride or PVC , The base can be made of steel or other metals.

The magnets of the magnetic lock 20 and of the magnetic key 90 may also further comprise metallic magnetic elements, composite and rare earth magnets. Suitable Kompositmagnete for the magnet, for example, ceramic magnets, ferrite magnets, Alnico magnets, Ticonal magnets, neodymium-iron-boron magnets, resin-based sphtzgussgeformte magnets, flexible synthetic resin or binder-based magnets, etc. Individual components of the magnetic lock 20 and the magnetic key 90 may also be magnetized, or made of permanent magnets corresponding to a predetermined magnetic patterns in order to satisfy desired functions.

The magnetic lock 20 is robust and reliable. It is unlikely that vibrations or clumsy handling destroy the magnetic lock 20th This properties allow that

Magnetic lock may be used in a wide range of applications 20, for example as a backup for bandages systems, as a bearing lock, or as a security label for clothing and luggage bags.

The magnetic lock 20 can be easily integrated into other applications. For example, the housing 24 of the magnetic lock 20 may be an integral part of a door with a child safety. The base 22 of the magnetic lock 20 may be mounted on a frame of the door. A device having the magnetic lock 20 may be produced with an integrated locking function using the magnetic lock 20th

The markings 72, 74, 76, 78, 106, 108, 110, 112 on the housing 24 and the magnet key 90 provide for easy release. The markings 72, 74, 76, 78, 106, 108, 110, 112 provide a user guidance in the use of the magnetic lock 20. The markings 72, 74, 76, 78, 106, 108, 110, 112 can also serve as part of an ornament the magnet lock 20 and of the magnetic key can be used 90th

The magnetic lock 20 requires no external power for operation. For example, 20 required for the magnetic lock to operate without battery, the additional costs and a loss can cause loss of power due. The magnetic lock 20 is a closed system which can be operated independently.

Alternatively, the housing 24 may be shaped differently, such as cubic. When the housing 24 has a rectangular-shaped top surface, a magnetic key which mates with the top surface, easily unlock the magnetic lock 20th Here, the correct positioning of the magnetic key 90 is facilitated on the magnetic lock 20 by the shape of the magnetic lock 20th Other shapes in which the magnetic key 90 forms a counter-mold to the magnetic lock 20, are also possible.

According to an alternative, the circumferential pedestal groove 42 may take a different form, which mates with the Magnetmitnehmern 36, 38th Instead of two Magnetmitnehmer 36, 38, a single Magnetmitnehmer may be provided, for example, then when the opening 26 is provided near the side wall of the housing 24th The base 22 may also be made in another form, which can be blocked by the Magnetmitnehmer 36, 38th For example, the base 22 may have a square cross section, triangular cross-section, a polygonal or other shape. The opening 26 can accommodate the base with the game.

The housing 24 of the magnetic lock 20 protects the Magnetmitnehmer 36, 38 from vibrations, corrosion and radiation etc. from the outside. Even if the housing 24 of the magnetic lock 20 is dropped from a height, the inner Magnetmitnehmer 36, 38 are protected against breakage and scratching.

The circular magnets 44, 46, 48, 50 of the magnetic lock 20 provide driving forces for opening and closing of the magnetic lock 20. If no external magnetic is present, the circular magnets pull 44, 46, 48, 50 to the Magnetmitnehmern 36, 38, so aufeinender that they move until they reach the locking position shown in Figure 2 and fix the socket 22nd

According to a second alternative, the Magnetmitnehmer 38 may be freely rotatable 36, as shown in FIGS. 9 to 17 and the key magnets be fixedly disposed in the key. According to a third

Alternatively, the lock magnets can be guided by a guide means and the key magnets be disposed on a turntable, as shown in Fig. 27, 28. This applies mutatis mutandis here in connection with FIG. 21, 22 with respect to the displacements 125, 217 of the key magnets of the lock magnet Illustrated for all alternatives.

The operation of a magnetic key according to the first alternative discussed above with Fig. 8. Here, the correct placement position can be found by feeling the force action or by aligning the marks. In addition to these two options or alternatively to the markings also a positive connection between magnetic keys and magnetic lock is possible, as for the magnetic lock of FIG. 27 - explained the 30th So that the proper landing position is set.

When placing a magnetic key according to Figure 27 - 29, the steps are used 133 of the magnetic key 90 'into the recesses 210 on the upper part 25 of the magnetic lock 20th By the magnetic attraction force between the key magnets 99 ', 100', 102 ', 104' and the lock magnets 44, 46, 48, 50, the hub 137 of the magnetic key 90 'rotates, so that the key magnets 99', 100 ', 102 104 'align to lock the magnets 44, 46, 48, 50, that opposite poles face each other. Further, the lock magnets 44, 46, 48, 50 of the key magnets 99 ', 100', 102 ', 104' moved into the unlocked position, as described in Fig. 8.

When placing a magnetic key to a magnetic lock according to Figure 9 to 17, the lock magnets 44, 46, 48, 50 direct the freely rotatably arranged Magnetmitnehmer 36, 38 as the key magnets 99, 100, 102, 104 from that opposite poles face each other. Further, the lock magnets 44, 46, 48, 50 of the key magnets 99 ', 100', 102 ', 104' are pulled into the unlocked position, as described in Fig. 8. This is done because the acting between the lock magnets 44, 46, 48, 50 and the key magnet 99 ', 100', 102 ', 104' attraction force in the aligned position is just slightly greater than that under the lock magnets 44, 46, 48, 50 attraction acting.

In the absence of a magnetic key and a corresponding external magnetic forces, the magnetic attraction forces of the magnet lock 44, 46, 48, 50 act together so that the pull Magnetmitnehmer 36, 38 from each other even in the locking position.

In addition, also a not shown here spring mechanism such as a compression coil spring, an extension spring, leaf spring, elastomeric block or a rubber ring - such as in EP1 355 550 are provided, which moves the Magnetmitnehmer in the locking position and holds it in the locking position. The key magnets must then be dimensioned so that they can overcome the attraction of the Castle magnet and the opposing force of the spring mechanism. reference numeral
