Abstract

Latching device (13) on the retainer (5) has latching member (8,9), which can move between inoperative and operative positions, having sloping faces (10) through which they are brought into the receiving position by the movement of the bolt and return again when the bolt moves into the inoperative position.

Description

The invention relates to a locking device for holding a bolt in one Closed position, in which the bolt at the end of a closing movement in a frame movable door or door leaf or wing or the like room closure element can be snapped on, with a counter bearing for the bolt, held in particular on the frame or another room closure element Holding device.

Such locking devices can be found in practically every apartment door, mostly in Form of a striking plate embedded in the frame with a receiving opening for the bolt. Even with single-leaf gates that can be pivoted overhead, as in the Most private garages are found, similar locking devices come for use.

Door or gate leaves are usually supposed to be simply slammed without manual Operating an actuator for the bolt can be closed. For this purpose, the latches for use with known locking devices as Snap formed, which has a slope facing the locking device has over which he by attacking an outer side of the closure device is pushed longitudinally into the interior of the door or gate leaf and at the end of the Closing movement of the door or door leaf in the closed position in which it is held by the closure device, snaps. It can be straight with solid or rigid bolts or more complex locking devices as is often the case with overhead garage doors that the spring force, with which the bolt must be preloaded as a snap, together with the resistance the bolt is so large that considerable forces to slam the door or Door leaf are necessary, which can lead to considerable noise pollution. Because of these possible forces, the bolt must also be quite massive and corresponding run thick. In addition, the trained as a snap must Latch provided slope should be sufficiently steep because of the forces involved the higher the flatter the slope with respect to the outer side of the closure device is. If the slope is steep, on the other hand, it is an easy implementation the locking movement of the door in the longitudinal movement of the bolt possible. A steep slope can only be placed on a correspondingly thick bar. According to the thick bars and the forces that occur, known locking devices must be used be dimensioned relatively large, which is why they are not for all areas of application are suitable. You only have to do this once at any door of an interior view the striking plate and the opening for the door latch and clarify what proportion of the frame depth on this from the opening and striking plate existing known locking device falls. Especially with Garage doors it is often desirable not to install the locking device in the frame, but on the frame, for example on the lintel or on the side area. Likewise, the bolts are usually not in the door leaf, but on the Inside of it. This is desirable, among other things, because of the changing local conditions greater flexibility with regard to the Position of the locking device-bolt combination is desired. Known locking devices and / or the bars that can be used with them are for such Uses mostly not flat enough for aesthetic reasons or the due to local space, which is often only available to a limited extent To meet requirements.

The object of the invention is to provide a closure device of the generic type to be designed in such a way that it can also be used with flatter bars and yet the closing of the door or gate leaf or the like room closure element is easier and quieter by slamming.

This object is achieved by a snap device held on the holding device, the at least one from a rest position into a receiving position and movable back catch element with a bevel to be grasped by the bolt in the course of the closing movement of the space closure element and to convert the closing movement into a movement of the catch element from the rest position to the receiving position, in which the path of the bolt in its closed position is released, and a feedback device for automatic Return the catch element to the rest position in which the path the bolt is locked out of the closed position to hold the bolt, having.

The closure device according to the invention thus itself has a type of snap on, which is why not designed as a catch latch in the locking device can snap and can be held there. Accordingly, you can also flat bars can be handled without a slope, which is why the invention Closure devices are flatter than the previously known executable are. The catch arranged on the closure device according to the invention is easier to operate than a catch that can be designed as a bolt because there are no connecting elements moved to a castle or a similar actuator Need to become. Especially because of the possible flat design, the Closure device according to the invention also variable as a closure device for an overhead garage door is attached to the side frames or to the top frame become.

A locking device with a combination of such a locking device and a matching bolt for locking a room closure element, In particular, a garage door leaf that is movable overhead is the subject of independent claim 15. The bar is in a conventional manner between a locking position and an opening position relative to the space closure element movable. Then to close the room closure element the latch can be brought into the locking position and then the room closure element be slammed, causing the bolt over the slope Snap device operated and so in its closed position in the locking device reached. An opening of the room closure element is by moving the latch - For example, by actuating a lock or a similar actuator - In its open position possible in a conventional manner.

Advantageous embodiments of the invention form the subject of the subclaims.

According to an advantageous embodiment of the invention, the catch element is as a closing wing element is formed, which carries the slope on an outer side and provides a counter bearing surface for the bolt on an inner side. The movement of the closing wing element takes place in one plane, which is essentially is parallel to the counter bearing surface. The direction of movement is therefore roughly parallel to the counter bearing surface. As a result, the catch element can cross to the counter bearing surface run very stiff and stored accordingly to high counter-bearing forces to deliver. In the direction of movement, with appropriate storage, it is easy Movement achievable. This movement is preferably a rotary movement, i.e. of the The closing wing turns under the influence of the bolt on the slope out of the way of the Bolt away to its closed position and as soon as the bolt on the closing leaf element has moved past towards its closed position, the Closing wing under the influence of the feedback device back to its rest position, where it blocks the bolt's path out of the closed position. For this the closing leaf is preferably rotatably riveted to the holding device, wherein the rivet attachment represents the axis of rotation. The feedback device can be simple be realized in that the catch device in the holding device attached that the catch element under the influence of gravity again and again falls back into its rest position so that it snaps into place even without a pretensioning device, which biases the catch element into the rest position, or at Failure of such is possible. However, the feedback device is preferably included such a biasing device, in particular one with a spring element such as a coil spring or the like. So that the catch element at Returning to the rest position does not move beyond this, slings can be used be provided and in particular also damping means, which is a special enable silent striking.

The closure device according to the invention is also readily available with only one Snap element conceivable. Preferably two catch elements are to be provided, so that the movement paths of the individual catch elements are shorter can. For this purpose, the individual catch elements are as already mentioned above can preferably be rotatably attached closing wing elements, in an advantageous Embodiment of the invention arranged such that it moves during the movement move from the rest to the receiving position away from each other. Thereby give them a wide gap for the bolt with little deflection between them free. According to an advantageous embodiment of the invention, the two touch Locking leaf elements are in the rest position each other so that they are mutually Slings and, if other slings, are also missing as dynamic slings to serve. In the latter case, one wing element pulls the other, i.e. if one is deflected closer to the center, the other closes all the more more on. In this embodiment, the pretensioning device has two opposing ones Snap elements prefer a coil tension spring, which the two Catch elements are connected to each other under tension. Construction and manufacture the snap mechanism with two snap elements are particularly simple feasible if the catch elements, their storage or fastening and / or whose movement corresponds to each other in mirror image.

The holding device is preferably, for example, via a plurality of elongated hole fastenings can be variably attached to the frame. An even more variable version is one in which the Holding device has two holding parts, a first of which in one direction adjustable on the frame and the second adjustable in a different direction on the is first attachable. The catch device is then on the second holding part held.

An advantageous embodiment of the locking device according to the invention has a flat bar with a front and a parallel back on. The bolt is therefore not provided with a slope, as is the case in the Technology is provided with snap-in locking devices. In addition Position deviations can occur in or instead of the variably adjustable holding device between bolt and the locking device serving as a counter bearing device be compensated for by a bolt adjustment device. Means the bolt is in position relative to the room closure element, i.e. a garage door leaf, a door leaf or the like, in position along an end edge, over which the bolt protrudes, or adjustable in the release length. For setting the position of the bolt adjustment device is adjustable on the space closure element definable guide element on which the disengagement and engagement movement of the bolt is led. So that the bolt does not jam even when it is away from its normal position at a greater angle are guide walls, with which the guide element engages the bolt, convex to the bolt, for example as a circular cylindrical surface or circular conical surface. A deviation from the Alignment of the bolt from a perpendicular to the end edge Alignment with the closure device according to the invention is therefore particularly so possible because the catch device with the slope on the locking device and not on the latch. Therefore, the invention Locking device also at a more or less large angle Pick up and hold the attacking bolt. With conventional locking devices against this would change the orientation of the latch cause that the slope arranged on the latch is no longer clean on the Edge of the locking device can attack, so that the latch is rough on the conventional closure device would open without snapping.

With solid lines, the bolt 3 is shown in a stop position, the one Position of the door leaf 4 corresponds just before its closed position, and with Dashed lines, the bolt 3 'is shown in its closed position, that of the closed position of the door leaf 4 corresponds. The closure device 2 has a Holding device 5, consisting of a first holding part 6 and a second holding part 7, and two closing wings 8 and 9. The closing wings 8, 9 correspond to each other mirror image. They are each provided with a slope 10. Using rivets 11 they are attached to the second holding part 7 such that they are about the axis of the rivets 11 are rotatable and that the bevel 10 points away from the upper frame 1, so that the Bolt 3 in its stop position, the slope or slopes 10 with its one Front surface 31 detected laterally delimiting edges. On the top frame 1 facing side are the closing wings 8, 9 with counter bearing surfaces 12 for the bolt 3 'provided in its closed position. The rotating plane runs within the the closing wings 8, 9 are rotatable about the rivets 11, parallel to the counter bearing surfaces 12. The two closing wings 8, 9 are part of a snap device 13, the enables the latch 3 to snap in from the stop position into the closed position, without the latch 3, 3 'having to be moved relative to the door leaf 4. Both holding parts 6 and 7 each have a recess in the area of the closing wings 8, 9 15, 16 on. The second holding part 7 is by means of second slot fixings 17 adjustable in the horizontal direction perpendicular to the lintel or the top frame 1 the first holding part 6 attached. Thereby delimit the recess 15 of the first Holding part 6 and the recess 16 of the second holding part 7 an open downward and on the side facing away from the upper frame 1 through the closing leaves 8 and 9 limited space 14 in which the upper end region of the bolt 3 'in the closed position is recorded.

As can be seen from FIG. 2, the first holding part 6 is by means of first elongated hole fastenings 18 towards and away from the gate opening, i.e. in the illustrated Example up and down, adjustable attached to the top frame 1. The closing wing 8, 9 are rotatable in a mirror image arrangement on the rivets 11, the rivet heads are identified by the reference number 19, rotatably mounted such that they away from each other from a rest position (shown in bold lines, reference numerals 8 and 9) in a receiving position (shown in thin lines, reference numerals 8 'and 9') can rotate. One from a coil spring 20 and to the Closing wings 8, 9 arranged fastening tabs 21 for fastening the ends the coil spring 20 existing biasing device 22 tensions the closing wings 8, 9 to the rest position. In addition, the closing wings 8 ', 9' fall through Gravity keeps coming back from the shooting position to the resting position, if no forces act on the closing wings 8 ', 9' against it. Corner areas 23 of the first holding part 6 on the edge of the recess 15 act as stops for the Closing leaf 8, 9 in the rest position. In addition, a damper 24 is provided the stop of the closing wings 8, 9 with one another or at the corner regions 23 dampens.

The closure device 2 forms together with one arranged on the door leaf 4 Latch arrangement 26 a locking device 25 for locking the door leaf 4 in its closed position. The latch arrangement 26 comprises the latch 3 (3 ') and a latch adjuster 27. The latch 3' includes one at one end a locking bar 28 fastened flat locking tongue 29. The locking bar 28 is at the opposite end of the locking tongue 29 with a not shown Actuating device in the form of a lock. By pressing the Castle can be the lock tongue 29 disengaged in the drawing Locking position, and to open the door leaf 4, the closing tongue 29 engage in an open position, not shown, in the rear surface 30 is brought from the detection with the counter bearing surfaces 12. The front surface 31 of the closing tongue 29 runs parallel to the rear surface 30.

The bolt adjustment device 27 comprises a guide element in the form of a Edge of the door leaf 4 attached bracket 32. For adjusting the horizontal relative orientation between the locking tongue 29 and locking leaf 8, 9, the bracket 32 is by means of third slot fastenings 33 adjustable parallel to the edge of the door leaf 4 attached to the same. In the middle, the bracket 32 points one away from the door leaf 4 stepped area 34 so that a guide channel between the door leaf 4 and the bracket 32 is formed, through which the locking tongue 29 is guided. Gradations 35 between the stepped area 34 and the remaining sub-areas of the Bow 32 are circular or arcuate, so that they to the locking tongue 29 out convexly formed guide walls, the side guide of the Latch 3, 3 'without inclination of the same relative to the guide channel Ensure jamming.

The bolt adjustment device 27 also has a disengagement length adjustment device 36 on for adjusting the release length of the locking tongue 29. The release length adjusting device 36 includes a fourth slot 37 between the Locking tongue 29 and the locking rod 28. The elongated hole fastening 37 enables adjusting the relative position between the locking bar 28 and the Locking tongue 29 parallel to the direction of longitudinal displacement of the bolt 3, 3 ', which can be initiated by the actuating device, not shown.

Preferred materials for the locking devices are sheet metal, in particular Sheet steel. The individual parts can be manufactured by stamping and bending.

The function of the locking device is described below. The relative Position between the locking device 2 and the bolt arrangement 26 is can be optimized with the elongated hole fasteners 17, 18, 33 and 37. To close the Door leaf 4, the bolt 3 does not necessarily have to be brought into its open position. Rather, the latch 3 can remain in the locking position and that Door leaf 4 can be easily pulled from its open to its closed position brought without having to operate the actuator. For this purpose, the bolt 3 is preferably biased into its locking position. As soon as the latch 3 reaches the stop position shown in FIG. 1, grasp the edges the front surface 31 of the locking tongue 29, the bevels 10. With progressing Movement of the door leaf 4, the closing leaves 8 'and 9' due to the detection between bevel 10 and locking tongue 29 in the receiving position shown in Fig. 2 brought, whereby the path of the locking tongue 29 through the recess 16th is released into the room 14. As soon as the bolt 3 'in the shown in Fig. 3 Is in the closed position, the closing wings 8 'and 9' by the Gravity and the biasing device 22 rotated back to the rest position. Here The damper 24 dampens the stop at the corner regions 23. The rear surface 32 detects the counter bearing surfaces 12 on the closing wings 8 and 9, whereby opening of the door leaf 4 is prevented. The actuating device is used to open the door leaf 4 actuated, causing the locking tongue by longitudinal displacement of the bolt 3 'pulled from the detection with the counter bearing surfaces 12 down becomes.

The locking device 25 is particularly good as a third, arranged at the top of the door leaf Closure can be used, a first and a second closure Lock the door leaf on the sides. Of course, the locking device 25 but not limited to the arrangement in the area of the upper frame 1. The order can be at the top, bottom and on the sides of a door opening.
