Abstract

A device that can normally, after a scar-controlled electrical impulse by means of a door pressure knob rotation, also carry an otherwise key / lock knob-driven locking piston, drop latch as straight / hook latch, on a conventional outer door lock, in which the transmission is provided with belt (6) members, "pulleys" (5), co-rotatable and pivot shaft (1, 2) respectively.

Description

535 211 2 above current lock box (and whether your pressure, knobs etc. are reassembled). This can be done on the surface of the door leaf and through the two just mentioned larger holes 3 (possibly with a pin extension) or close to the locking box through a larger, recessed cavity, 9, in the door leaf.

The design could be single- or double-sided flip-flops / yoke connected with link or wire.

Various disadvantages such as. that when operating link / wire is centered towards the center axis, weakening the torque, and that counter rotation direction knob / pressure as well as knob angle more than 90 ”is difficult to master, this solution does not dry out, although it is included in the heating tank.

In a dry embodiment, the resp. pin mounted on a member ("(rcm) disc"), 5, circular or at least of such a large (crescent / moon phase-shaped) circular segment that its periphery is not interrupted at full thrust, of the type pulley, sprocket, etc., and are mechanically in mirror-symmetrical loop connected per (gear) strap, chain, wire, Bowden cable etc. ("strap"), 6, so dumbly attached that it can not slip on either periphery. Because the peripheries are never interrupted within the stroke, the wheel diameter and thus transmitted torque remains constant / linear throughout the stroke and since the loop is closed, i.e. the belt goes unbroken around the turn (although the belt can be in different pieces), the moment is independent of direction, which means that the belt, which is typically "soft", never has to push, but always pull, both back and forth, and that no return springs etc. ., which of course increases the power requirement, is needed (advantageous especially with Bowden cable with soft inner wire). The belt (B-shaped) can be crossed over the intermediate pulley, 7, or own part, with which the counter rotation / knob rotation can be mastered. Bowden cable (in casing) can be particularly suitable for this. Where fastening screws etc. are to pass through the discs, suitable (bracket-like) slots, 8, can be removed, which for a solid through-screw can suffice at a turning angle of approximately 90 °. At a larger angle, the screws may be split. One of the pulleys may have an adjusting screw or equivalent for belt tension, positioning, tuning, etc ..

Preferred belt power transmission solution provides special advantages as (despite increased standardization still occurring) different dimensions, distances, locations, relative directions, etc. of existing locks, can be easily and straightforwardly mastered with the help of a few equally functional basic components, mostly with adaptation of the units and, in prefabricated units. in housing e, the mutual location of the components there. It can be noted that, depending on the type of lock, the full stroke of a pressure is about 45-60 °, while the knob for complete control may have to be turned 90 - 360 °. This can be regulated with different disc radii, or that (at 360 ° rotational range) with e.g. by means of a freewheel / reverse locking mechanism a few strokes are "pumped" with the pressure. At 360 ”, the timing belt or chain and full circle periphery of the discs should be best.

Assuming that a unit adapted and prefabricated (in casing) adapted to a certain standard / lock type is at hand, two general types of rules and some preferred non-limiting embodiments of the present invention are described below and with some drawing reference in more detail.

Straight rule (and hook rule 1: Here the pressure / rotation direction is usually the same. The discs are dullly connected with a belt so that if one is moved, the other is included. At least one disc (or its belt-driving periphery), preferably and here referred to it on the pressure shaft , can be connected to / disengaged by means of preferably electrical control impulse relative to the shaft pin it is placed on.

When disengaged, the rotation of the pressure (due to the disc that comes with it) will not rotate the axis of rotation (or the rotation of the pressure shaft). When, on the other hand, connected, the pressure will bring the knob (and vice versa) and thus the straightening rule, and with the same force in both unlocking and re-locking, which the latter of course with straightening rule usually takes place with deliberate active action.

The control pulse for at least connection can e.g. be electric, activating an engaging solenoid. Exemplary embodiments thereof will be described later. The control command for the pulse can be given distally outside in known ways (from the inside the knob can always be used, but also per key; control command; switch etc.) Logic / mechanics for converting command to impulse can in a known way be found on board; and electricity can be supplied by cable or on board battery. 535 211 3 The duration of the solenoid intervention can be regulated in a known manner per program or position switch.

Where, after a first remote-controlled (keyless) unlocking / entry has taken place by means of turning the outer pressure, the pressure in the turned-down position is disengaged, the rule remains in the unlocked position (unless locked from the inside with the knob), allowing comfortable unlocked entry / exit, e.g. during visiting hours. At the final exit, it can be locked from the outside (per key or) by turning down the external pressure, issuing the connection command and then turning up the pressure. Due to the robust mechanical coupling pressure / knob, most cases of skewed, kinking etc. door / lock situations can also be handled; at least as well as otherwise per key / pressure / knob and in no case consumes any (motor) electrical energy - advantageous in battery drilling (for logic / solenoid).

Fall rule: With the retention of circumstances / logic / mechanics etc. as described under Rakrçgel above, the known fall rule differs in that it automatically returns to locked when the door is closed, so no special active locking needs to be done at the final exit; and for unlocked comfortable e.g. day pass, it can usually be manually "set up". In addition, as has already been discussed with the exemplary and non-limiting constructive solution for this (Fig. 4), the direction of rotation between the knob and the pressure is often the opposite.

The above is generally illustrated by Figs. 1-4, where Fig. 1 visualizes a known locking side aspect; Fig. 2 is intended to schematically show a placement with a strap over discs with a full circle periphery; Fig. 3 the same visai circular segment slice. Fig. 4 shows simplified (and with different-size discs, indicating gear ratio) crossed straps over its own part or over the intermediate disc and where a side view indicates how the strap can run separately over the intermediate disc without chafing; other discs can also have such separate paths, while crossed Bowden cables (in casing) cannot rub.

To describe in more detail an exemplary preferred embodiment of how the pressure shaft can be connected / disengaged relative to its attached disc (or rocker, yoke, peripheral section at circle segments, etc.), or, as described here, at least its reaming periphery, reference is now made to Figs. .5. Many other ways and dispositions can of course be conceived / arranged, giving a similar result. For example. can friction / magnetism instead of piston bind together; discs or lamellae (ef. car "coupling") on the same drive shaft - a disc (lamella) dumbly connected to the drive shaft and a free-rotating one, until the (at least) two discs are brought together upon actuation, causing the pulley to co-rotate (outlined by F in g.7) so driving the (fixed) disc of the other shaft; or that the shaft journal is engaged / disengaged relative to an integral disc 5 (outlined by Fig.6).

A belt-carrying periphery 5 can rotate freely around a pressure pin-mounted inner disc 52 and is provided with a recipient 53 into which a piston rod 54, axially slidably mounted on 52, can be inserted, joining 5 and 52 so that when 52 rotates, the rotation is brought about. 54 is a pressure spring (55) - biased so that normally 54 has a home position completely within the 52's peiiferi (whereby 5 is disengaged). 54 is divided into two arms around the pressure shaft pin 57 and then goes together in a transverse ferromagnetic end piece 54: 2 a sufficient distance beyond 57. 54/54: 2 is as said axially wearable and is kept within given limits of pins, fi springs / end stops, strips etc., only hinted at in Fig. 5. In the free space between the front end position of 57 and 54: 2, a solenoid 56 with an action end towards 54: 2 is located so that when power is released, 54: 2 leaves its (rear) home position and goes to its front end position, ie stop towards the solenoid, whereby 54 enters 53 and thus 5 is connected to 52 (and the periphery is caused by pin rotation). When the power is cut off, 54 returns to the down position and 5 is disengaged.

For undivided disc 5, Fig. 6 exemplifies a related solution. When the solenoid 66 pulls, the slide 64 is cramped about the pin 1 and the disc and the support disc 5 are connected. Spring 65 is a tension spring here.

The disc-mounted solenoid-etc. assembly is then preferred, e.g. Standardization of components etc. is facilitated as the mechanism of the pressure drop plate etc. can usually be identically the same and the caused variation can be handled most with adaptation / dimensioning of strip type / length / crossing, possibly. intermediate disc, rotary disc peripheral radius, housing, etc .; and that the space between the discs in most 535 211 4 cases is kept free and can be filled with ev. battery, receiver / logic circuits / components etc .. In case of intermediate disc can be superimposed with e.g. logic circuit board.

Fig. 7 a and b schematically exemplify a possible lamella design where a indicates friction and b hooking, when the lamellae are brought together in a known manner by command. 71 is drive lamella, but relative to its shaft journal 1,2, 72 is belt lamella (disc 5), by means of the bearing 73 freely rotatable and displaceable on 1,2.

Earlier here, lashes, yokes, etc. have been mentioned. Although not advantageous or all-round, however, at cza 90 "'s angle of rotation (and also in the opposite direction of rotation) a double-sided rocker on selection fi in pin axis could replace a disc if designed with (eg 90 °) angle between the arms (Fig. 8) so that when one arm has reached the dead center, the other arm is in the drive position for rotation; and if the rocker shaft on the pressure shaft is larger than the corresponding one on the rotary shaft, a stroke angle of less than 90 ”on the pressure shaft can be handled. Although not preferred, it, 81, and similar embodiments are included in the invention. It is also conceivable to be included in a disc, 5, which is also shown in Fig. 8.

Fig. 9 is intended to illustrate that at least one of the discs 5 can be laterally arranged its shaft pin and via intermediate gears 91 el. dyl. indirectly driven by direct intervention el. dyl. by / with a pin-mounted drive means.

In conclusion, some other possible embodiments and details contained in the inventive concept will be elucidated; and also other modifications are possible within the scope of the invention.

A solenoid can be functionally replaced by e.g. bi- / memory metal, hydraulics, pneumatics or an electric motor and e.g. snåckdrev pulling / shooting e.g. a wear. This requires considerably less (and always the same) energy than if an entire locking piston were to be driven by a motor. Solenoid etc. can of course be placed in, for example, free middle space between the discs, maintaining the basic function.

It is also possible (although not preferred) that at least one disc for free / connection for fl is moved side / height a sufficient distance, so that it thereby goes out / engages to the rotation of its pin.

Since the disc deflections are always strictly limited and well-defined in the various assigned functional phases, the interventions, push / command handling, etc. remain unambiguous and uniform. With both battery and supply drive fl (then with onboard UPS complement), it is possible for doors of evacuation type etc. for example. with automatically issued special command signal ensure that connection takes place directly at e.g. fire alarm, power failure, etc., so that the door with the external pressure (and of course also the internal pressure / knob) can be opened directly by any auxiliary person. In the particular case, a power failure can (in the case of line power supply) correspondingly be emitted when the spring 65 in Fig. 6 is still drawn and the solenoid 66 draws as long as supply current is supplied, but that the square cavity in 64 intended to grip the pin is located in the direction of the solenoid. . An analogous solution can of course also be provided in the dispositions according to Figs. 5 and 7. Also, a device according to the present invention, compact or distributed, in whole or in part, could be fitted during manufacture as it fits in or outside a lock case - and accommodated in the storage tank. but primarily the present invention aims at providing already installed locks an EAC (Electronic Access ControD capability, which is furthermore simple, robust and affordable and of good practical operation.

Internal locking knob can be substituted by exit switch or command, which later, as well as internal key knob, complicates the so-called outbreak, i.e. free door exit in the event of a burglary, for example through a window (However, the emergency exit problem must be taken into account). Outer keyhole / slot can be covered or eliminated, whereby the lock becomes completely "keyless" and can be activated from the outside only after a scar command. Both right- and left-hung doors can be operated without further ado. Where pin 1 in the drawing, etc. is indicated, pin 2 can often be thought of as well. A disc 5 can also be so-called terrace-shaped, so that the belt 6 or the equivalent runs in a separate path, enabling different gears at discs 5 of otherwise uniform (standardized) format. The disc circle periphery can be varied towards e.g. the parabola or polygonal hold to and need, as shown above, not always be complete but can be interrupted when appropriate; and at a twist / push stroke angle of about 90 °, a single Bowden cable with rigid input wire in only a single loop / line could transmit rotation in both directions, all of which is also intended to be contained within the present inventive concept. 535 211 5 The fact that you want to substitute / supplement key unlocking with EAC, has not only to do with security, but perhaps just as much with comfort, such as code / card / "tag" lock, intercom, etc ..

With the present invention, it is possible in a relatively simple and inexpensive manner to advantageously obtain the execution stage in EAC unlocking. The command line is then the only one left to obtain a complete and functional EAC system of user-desirable configuration.

In view of the component miniaturization that now exists and the relative size of the present device, an ordering component of an appropriate type can also be built into the housing with great advantage, as common needs such as housing, power supply, electronics, etc. can be shared.

Simplest, advantageous and without the need for investment in expensive input means such as keyboards, mic / speakers, cards / biometrics readers (but not exclusively those from the idea of invention), a full EAC input / control capability can be obtained using close-range radio communication such as RFID, WiFi, (W) LAN, Bluetooth, NFC, which is available in the form of ready-to-use, very small modules.

Without going into more detail here, however, it is hereby indicated that with great advantage such components can be integrated in the present inventive device and then best and cheapest within its housing.

It appears from the above that modifications are possible without departing from the inventive concept.

Spec. for pin connection mechanisms there are many, i.a. g: m the aforementioned patents previously known; in the present application indicated; and otherwise conceivable, solutions / variants available and optimally constructed according to what turns out best in tests etc.; and their embodiments now shown are thus in themselves not limiting or critical to the present invention as described and required herein. Also, it has previously been described here how the belt-bearing periphery of the pulleys can be varied in many ways and some possible, though not necessarily preferred and absolutely not limiting, designs have been indicated; and which is intended to be expressed in the definition "fully or not fully closed circular, rounded or polygonal shape". For obvious reasons, the drawings are kept in sketchy format, as a more detailed design could be taken unnecessarily for such an embodiment to be preferred.
