EP1236851A2 - Locking/grip device for a gate; in particualr a garage gate, or a door - Google Patents

Abstract

The lock and garage assembly for a garage door has manual or power operation. The lock operation in either mode is through a sliding plate (12) which is moved and transfers the movement to the lock. The slide can be in two parts, with the actuator drive operating on one part of the slide (24), which the rounded locking projection can move through.

Description

The present invention relates to a locking / grip device for a goal, especially one Garage door, or a door with which locking elements can be blocked, released and driven for the gate are to move the gate from a locked state into one Unlocked state and transfer back again.

Devices of the type mentioned are for example known in the form of T-shaped rotary handles, which with one hand can be grasped and when turning one Lock or unlock the gate. At the same time, this can be T-shaped Handle or handle the gate open or be drawn in. The rotation of the T-shaped handle can by actuating an assigned locking cylinder, which is operated via a key, locked or be released to block the gate or to unlock.

These known locking / handle devices are associated with a number of disadvantages which the seeks to eliminate the present invention.

So, burglar security has been an in lately increasingly acute problem. For locking / handle devices the one described at the beginning Art doesn't make it for a savvy burglar Problem is the plastic plate, which handle and Embedding the lock cylinder flush, then prying it off the locking cylinder protrudes over the surface of the gate and turned under the influence of violence can be. Carried out in the applicant's house Experiments have shown that with a suitable tool, which, however, need not be overly specialized (a large screwdriver, a chisel and one Pipe wrenches are sufficient), one with a conventional locking / grip device secured gate in less than ten Seconds to open.

Another problem with known locking / handle devices with, for example, a T-shaped handle can be seen in the fact that especially with motor driven gates, e.g. ceiling sectional doors or side sectional doors, a certain risk of accident consists. This is because of the fact that the Door surface protruding T-shaped handle an opening of the gate itself, for example on a piece of clothing immediately before person caught in the gate, so that this Person pulled by the operator of the opening gate becomes. Children are particularly at risk in this regard.

Finally, a known locking / grip device with one from the gate surface projecting handle part is a disadvantage in that this reduces the clear passage height. Both sectional and overhead doors must be ensured be that the gate segment or the gate wing with the T-shaped handle located on it Opening and closing the frame can pass. This necessarily requires a certain amount of freedom between the gate segment or gate wing and the horizontal Frame or lintel, which among other things the clear headroom can also reduce.

In contrast, the present invention proposes one Locking / gripping device for a gate, in particular a garage door, or a door in front, with which locking elements can be blocked, released and locked for the gate are drivable to the gate from a locked state in an unlocked state and back again to transfer, the locking / grip device both manually and via a motor, in particular Actuator can be locked and unlocked and thus actuated is and where both the manual and the Locking and unlocking operations via the actuator on one in the locking / grip device displaceable backdrop arrangement act, which the actuating movements in corresponding locking and unlocking movements the locking elements implements.

In contrast to the previously common example T-shaped handle, which can be gripped by hand and is rotatable, uses the subject of the present Invention a sliding element or part to the movements and forces necessary for locking and unlocking to create.

This results in a number of advantages in particular a much improved security against burglary, eliminating the risk that, for example Garments on one protruding from the door leaf Catch grip part, one with the same installation dimensions increased clearance height, since the invention Locking / grip device as far as possible flush with the level of the door leaf can, an optically / aesthetically appealing design as well as increased functionality.

These and others with the subject matter of the invention associated benefits are in the following detailed description explained.

In a preferred embodiment, the Backdrop arrangement executed in two parts, the (especially motorized) actuator on part of the Setting alone acts with which the supply and Unlocking operations are feasible, and manual Drive acts on the second part, that during the unlocking process inevitably moved the first part. In practice this results as follows is explained in more detail, the advantageous aspect that a with regular motor drive of the gate Locking and unlocking released by hand in an emergency can be, for example, in the event of a power failure or the like the gate despite the no longer functional open or close the motorized actuator.

The second, manually operated part of the Setting arrangement is preferably lockable, for example via a conventional locking cylinder. The Tor is therefore only functional if you have one Remote control for the motorized actuator or at Possession of a valid key for the locking cylinder too to open.

Is also preferred when the second part is closed the first part can still be moved using the actuator, the gate can be closed manually despite the second one being locked actuating part of the scenery arrangement still over the motorized actuator opened and closed become. It is therefore not necessary to gate in front of the Initiation of motor movement by hand unlock or unlock; nevertheless the gate is in its closed position when switched off motorized actuator securely locked or blocked.

The second, manually operated part of the Backlit arrangement when actuating the actuator from the gate, it is ensured that the gate in an emergency can be opened by hand without breaking the Resistance of the motorized actuator works too need, which is usually due to the high Reduction ratios is practically self-locking and making it impossible to open the gate by hand would.

More details, aspects and advantages of Invention result from the following description based on the drawing.

Figures 1 to 5 show an embodiment of the present invention, while FIGS. 6 and 7 rather than schematic functional representations or models are to be understood. Nevertheless, they meet the figures 1 to 5 statements made below equally to Figures 6 and 7 and vice versa. Farther it is understood that the in the individual figures of the Design or functional examples shown in the drawing in no way to be taken as limiting are, but only the principle or that of the present Present idea underlying the invention and should play.

One designated in the drawing with a total of 2 Locking / handle device (hereinafter referred to as "handle device" according to FIGS. 1 to 3 essentially a rectangular in plan view Housing 4, which is approximately according to FIGS. 2 and 3 can be made in two with one later Fitted condition outer shell 6 and one Shell at the open end closing lid 8. The Shell 6 has an opening or recess 10, which allows access to a slider 12. The slider 12 has the function of a manual drive with which one with the handle device 2 according to the invention equipped door unlocked and opened by hand can be, as will be explained below.

The housing 4 of the handle device 2 is in the Figures 4 and 5 evident way in a door leaf 14 of a gate constructed in a known manner, especially a garage door. The door leaf 14 can be a so-called overhead sectional door, the reference number 14 in FIGS. 4 and 5 being a Section or section of this overhead sectional door would designate. Sheet 14 may as well become one Side sectional door belong, again the reference number 14 in Figures 4 and 5 a section or one Section of this side sectional door. Furthermore, the door leaf 14 can be made in a known manner Way trained swing gate, which in the Contrary to sectional gates across its entire horizontal or vertical extension in one piece and is rigid and is moved as a unit.

Figures 1, 4 and 5 also show schematically indicated that the slide 12 for receiving a Lock 16 is designed with which the slide 12th can be fixed relative to the housing 4. The castle 16 can be trained in different ways are, however, preferably a cylinder lock is known Design which, when actuated via a key 18 Locking elements actuated, for example retracting or extending or shifts horizontally or vertically, then these locking elements in positive engagement with the Housing 4 or parts thereof, so that the Slider 12 stationary relative to the housing 4, i.e. is fixed immovably. The locking element or the Locking elements are still from the inside of the gate accessible or actuable, e.g. after removing the cover 8 to the gate if necessary also from the inside by hand unlock and then open.

In the unlocked or unlocked state of the Lock 16 is the slide 12 inside the housing 4 in Figures 1 to 7 vertically up and down. For this purpose there is a handle recess or recess 20 provided which is accessible via the recess 10 and it enables the slide 12 to be shown, for example, in FIG. 4 upwards by an amount A within the housing 4 move.

As such the key 18 as long as it was in the lock 16 is inserted, strike the top edge of the recess 10 would, if the slide 12 is to be made is a prerequisite for Movement of the slider 12 that the lock 16 with the Key 18 unlocked and then key 18 must be deducted. Accidental cancellation of the Key 18 is thereby with high security avoided.

The slider 12 is, as in particular from the figures 2 to 5 emerges, formed in two parts, one Part of the slide 12, namely the one in the drawing 22 designated part, via the recessed grip 20 at unlocked lock 16 can only be operated by hand is. Another part 24 of the slide 12 is over a drive not shown in the drawing, in particular a motorized actuator, movable. Movement of part 24 does not result in entrainment of part 22, as can be seen directly from FIGS 5 results, whereas a movement of the (unlocked or unlocked) part 22 in the individual figures of the Drawing upwards due to a form-fitting system in a region 26 a rectified movement of the Part 24 conditional.

In any case, movement of the part 24 causes above or below a locking or unlocking process, such as will be explained in more detail below. The also as Gate arrangement, designable arrangement from housing 4 and the two parts 22 and 24 movable therein a linear movement of the part 22 and / or the part 24 in locking and unlocking operations, as on can best be seen from FIGS. 1, 6 and 7. For this has part 24, which is independent of the actuator of part 22 in the manner of a backdrop tour or Set arrangement of the housing 4 vertically up and down is ("vertical" on the representation in the Figures of the drawing related), two recesses 28a and 28b in which pins or bolts 30 are guided. The bolts 30 are in connection with locking elements 32, which is displaceable in the housing 4 or the cover 8 are stored. The locking elements 32 serve as an extension to a overhead sectional door on the side in the area of the door leaf / door frame transition arranged locking elements to press, which in the locked state lifting the Prevent overhead sectional door. How best from the Figures 6 and 7 shows one in said Figures upward movement of part 24 a Guide the bolts 30 along the recesses 28a and 28b, whereby due to the vertical or longitudinal axis L of Handle device 2 oblique course of the recesses 28a and 28b the bolts 30 are carried along in such a way that that after movement of the part 24 in Fig. 6 after above the bolts 30 along the recesses 28a and 28b guided and relative to the handle 2 inwards are performed, whereby the locking elements 32nd pull back into the handle 2. With one completely upward position of part 24 reach the bolts 30 according to FIG. 7 with the lower end of the recesses 28a and 28b in contact, and the locking elements 32 are completely withdrawn. This Position is the unlocked state of the handle device 2, whereas the state according to FIG. 6 is the locked state or locked state.

Alternatively or in addition to the locking elements 32 can further locking elements 34th be present, which are also in the housing 4th are slidably mounted and via bolts 36 and Recesses 38a and 38b in connection with the part 24 stand such that when the part 24 moves 6 and 7 upwards the bolts 36 Passing through the recesses 38a and 38b pulled up be to the locking elements 34 from the 6 in the unlocked state to bring according to FIG. 7. The locking elements 34 are especially for side sectional doors or Up-and-over doors shown with a side lock not or only via the locking elements 32 makes little sense.

When the part 24 moves from the unlocked position 7 back into the locking position 6, the bolts 30 and / or 36 slide along the recesses 28a and 28b and / or 38a and 38b, so that the locking elements 32 and / or 34th again extended in a straight line relative to the housing 4 be and directly or indirectly a locking process make the door leaf opposite the door frame.

To move part 24 to implement it with respect of the housing 4 vertically upward movement in as far as the locking elements 32 are concerned, for this horizontal or 90 ° deflected movements or, as far as the locking elements 34 are concerned smooth movements, engages on this part 24 a motor actuator in particular. This Actuator is, for example, by a rope or Bowden cable realized in the interior of the housing 4th occurs and for example in area 26 on part 24 the slider 12 is attached. The other end of this Cable or Bowden cable stands with a drive, in particular an electric motor drive for the door leaf 14 in connection. Here is about appropriate means, for example, an elongated hole between the Drive and the relevant articulation point on the door leaf 14, a certain empty or for driving the door leaf 14 Backlash exists, whereas the cable or Bowden cable to operate part 24 directly with the drive is in operative connection. This means that with one Start of the drive for the door leaf 14 part 24 is operated directly and in the individual figures the drawing above the cable or Bowden cable is pulled and unlocked the door leaf 14, whereas the actual drive of the door leaf 14 due to of idle or lost motion is not yet effective. First after ensuring that the gate has been unlocked the drive engages with the actual door leaf 14 mechanically and moves it. During the closing and locking process the movements are reversed, i.e. the actuator lowers the door leaf 14 or moves it in its closed position, after reaching the The drive is in the closed position within idle or lost motion further and over the rope or Bowden cable locks the gate. For this can in the area of the locking elements 32 and / or 34 actuated actual locking elements, force support means, for example feathers be, which when lowering the part 24, the corresponding Force latch components into their closed position or forced movement.

The functional sequence explained above assumes that the handle device 2 and the slide 12th installed in the manner shown in the drawing is and thus at least partially with gravity support during the closing or locking process is working. Of course, the slide 12 and / or the locking elements 32 and 34 alternatively or in addition to the spring elements in the actual Bolt components are spring-supported, so that the slide 12 under spring force from its unlocked position 7 in the locking position returns as soon as the cable or Bowden cable no longer applies force to part 24. hereby it is also possible to use the handle device 2 compared to the Install representations in the drawing rotated by 90 °, for example with side sectional doors, where then the locking elements 32 are used alone would be the side sectional door in the area of upper and lower frame set when the locked state is brought about.

In any case, this is the movement of part 24 independent of part 22, which is over the castle 16 is fixed relative to the housing 4, since how immediately from Figures 2 to 5 emerges the fixed Part 22 one up or down in the figures directed movement of the part 24 is not hindered. The Part 22 with the recessed grip 20 serves, as already explained, to this, the locking device 2 of the gate manually and therefore independently of the actuator repealed. For example in the event of a power failure or if the remote control for the actuator failed the door leaf 14 itself due to the failed actuator no longer open. In such a case first the key 18 is inserted in the lock 16 and by turning the key 18, the part 22 relative to the Housing 4 unlocked or unlocked. Then from below gripped here in the recessed grip 20 and the part 22 in those up in the individual figures of the drawing pointing direction, being carried in the Area 26 also raises the part 24 upwards Distance A overcomes and the locking elements 32 and 34 from the position of FIG. 6 to that of FIG. 7 be moved. However, the door leaf 14 would now be after as before not to move because of the motorized actuator is still in engagement with the door leaf 14 and due to the prevailing reduction ratios against not this manual actuator or muscle power can be worked on.

1 is therefore still a decoupling mechanism 40 provided, which consists essentially of a Lever 42 exists, which at 44 on the hand-operated Part 22 is pivoted and in one Recess 46 emerges from the housing 4 and therein is pivotally mounted. In the field of free At the end of the lever 42, this has an opening 48 who is attached to a cable or Bowden cable, whose attacks the other end on a lock with which the Actuator or door drive can be decoupled from door leaf 14 is. In the normal position, i.e. in the position for example according to Figures 4 and 5, in which the Part 22 locked in relation to the housing 4 is in the lower position and only part 24 the motorized actuator for the locking and unlocking processes is moved, the lever 42 is in that shown in Fig. 1 with solid lines Position, i.e. pointing obliquely upwards. In the event of a failure of the motorized actuator, which is a movement or activation of the handle device 2 manually Part 22 to be operated is required at a corresponding movement of the part 22 in the housing 4th up the lever 42 of FIG. 1 with its left lying free end counterclockwise pivoted below. Suspended in the opening or eyelet 48 Cable or Bowden cables act on the drive in such a way that this is uncoupled from the door leaf 14, so that the Door leaf 14 pushed open by hand or by muscle strength can be without doing this against the actuator (Electric motor, reduction gear, toothed belt etc.) to have to work on.

Then the door leaf 14 is closed again and the part 22 in its initial position according to the drawing returned and fixed there with the key 18, so the decoupling is a subsequent movement of the lever 42 the door operator lifted again, so that at a restart of the gate or actuator is again in engagement with the door leaf 14.

The lever 42 can, although not in the drawing shown in more detail, also under spring tension, a location-independent installation and a location-independent Ensure operability, so that the decoupling mechanism 40 also for example with a side sectional door can be used in which the Handle device 2 compared to the illustration in the Figures is rotated by 90 °.

• Der Zylinder des Schlosses 16 ist in dem Teil 22 bündig eingelassen bzw. aufgrund einer an dem Gehäuse 4 im Bereich der dortigen Ausnehmung 10 angeordneten Blende 50 (Fig. 4 und 5) als zurückgesetzt oder vertieft eingebaut zu betrachten und ist daher vor Aufbrechversuchen durch Abdrehen oder Abbrechen wirksam geschützt.
• Im Normalbetrieb, d.h. beim Betrieb alleine des Teils 24 über den motorischen Stellantrieb, ist der Schlüssel 18 abgezogen, da er nur zur Entriegelung oder Freigabe des Teils 22 bei manuellem Betrieb benötigt wird. Das Tor bzw. Torblatt 14 ist somit bei normalem Antrieb über den motorischen Stellantrieb in seiner geschlossenen Position stets verriegelt, da die über die Verriegelungselemente 32 und/oder 34 betätigten Riegelteile selbsttätig oder unter Federkraft einrasten und das Tor bei verriegeltem Teil 22 nicht von Hand hochgeschoben werden kann, da vom verriegelten Teil 22 keine Bewegung auf das Teil 24 und damit auf die Verriegelungselemente 32 und/oder 34 weitergegeben werden kann.
• Die gesamte Griffvorrichtung 2 fügt sich, wie aus der Zeichnung unmittelbar hervorgeht, flach und optisch ansprechend in das Torblatt 14 oder das zugehörige Torsegment ein.
• Da im Normalbetrieb der Schlüssel 18 abgezogen ist, gibt es keine wesentlich über die Ebene des Torblattes 14 hinaus nach außen vorstehende Teile. Insofern besteht keine Gefahr, daß sich beim Öffnungsvorgang des Torblatts 14 derart vorstehende Teile beispielsweise in der Kleidung verhaken und Personen, insbesondere Kinder, mitgezogen werden.
• Da die Griffvorrichtung 2 beidseits nur wenig aus der Ebene des Torblatts 14 vorsteht, erfolgt auch nur eine unwesentliche Verringerung der vom Torblatt 14 freigegebenen lichten Durchfahrtshöhe.
• Die Entriegelungs- und Griff-Funktionen in Öffnungsrichtung bei manuellem Betätigen des Torblatts 14 sind in einer Einheit kombiniert. Dies ist sowohl bei Decken- oder Seitensektionaltoren als auch Schwingtoren ergonomisch vorteilhaft.
• Das Torblatt 14 ist im Bedarfsfall auch von innen her manuell entsperr- und öffenbar. Hierzu muß z.B. der Deckel 8 abgenommen werden, um das Schloß 16 bzw. dessen Riegelelemente von Hand zu bewegen und danach das Tor(blatt) 14 aufzuschieben. Es können auch durch den Deckel 8 hindurch wirkende Betätigungselemente, die auf das Schloß 16 und/oder seine Riegelelemente wirken, vorhanden sein, um den Sperrzustand durch das Schloß 16 gewollt aufzuheben.

The advantages which can be achieved with the subject matter of the present invention can be seen in particular in the following:

• The cylinder of the lock 16 is recessed flush in the part 22 or, owing to a diaphragm 50 (FIGS. 4 and 5) arranged on the housing 4 in the region of the recess 10 there, is to be regarded as recessed or recessed and is therefore to be broken off before attempting to break open or Cancel effectively protected.
• In normal operation, ie when operating part 24 alone via the motorized actuator, the key 18 is removed, since it is only required for unlocking or releasing part 22 in manual operation. The gate or gate leaf 14 is thus always locked in its closed position in the normal drive via the motorized actuator, since the locking parts actuated via the locking elements 32 and / or 34 engage automatically or under spring force and the gate is not pushed up by hand when the part 22 is locked can be, since no movement can be passed from the locked part 22 to the part 24 and thus to the locking elements 32 and / or 34.
• The entire handle device 2 fits, as can be seen directly from the drawing, flat and visually appealing into the door leaf 14 or the associated door segment.
• Since the key 18 is removed in normal operation, there are no parts which project significantly beyond the level of the door leaf 14. In this respect, there is no danger that when the door leaf 14 is opened, such protruding parts get caught, for example, in clothing and people, especially children, are dragged along.
• Since the gripping device 2 protrudes only slightly from the plane of the door leaf 14 on both sides, there is only an insignificant reduction in the clearance height released by the door leaf 14.
• The unlocking and grip functions in the opening direction when the door leaf 14 is operated manually are combined in one unit. This is ergonomically advantageous for ceiling or side sectional doors as well as up-and-over doors.
• If necessary, the door leaf 14 can also be unlocked and opened manually from the inside. For this purpose, for example, the cover 8 must be removed in order to move the lock 16 or its locking elements by hand and then to slide open the gate (leaf) 14. Actuating elements acting through the cover 8 and acting on the lock 16 and / or its locking elements can also be present in order to intentionally cancel the locked state through the lock 16.

The course is in the illustrated embodiment of the recesses 28a and 28b in a straight line and to the longitudinal central axis L symmetrical by a certain angle arranged obliquely to this axis L. Are other movement relationships and / or processes required these recesses of course also another Have course, for example more or less strongly to Axis L be tilted and / or optionally one of deviating from the linear form shown, arcuate have a curved or other type of course.
