DETAILED DESCRIPTION

(7) Closure holders 1 are used for locking purposes, for example in the case of door closures. They have an undercut 4.2 which is engaged from behind by a bolt element, such as a bolt or a lock latch, a closure for locking a closing element, such as, for example, a door leaf, hatch cover, window casement/sash, cover or a flap, to a frame. For this purpose, the bolt element is typically arranged on the closing element and the closure holder 1 on the frame. Nevertheless, the closure holder 1 can also be arranged on the closing element and the bolt element on the frame. The bolt element and the undercut 4.2 form a lock here between frame and closing element. An opening which is surrounded by the frame and which can be, for example, a door, hatch or a window, can thus be locked in a simple manner.

(8) In order to permit uniform closing of the opening by means of the closing element and also to compress, for sealing purposes, a sealing element, such as a sealing lip or sealing bead, which is arranged between the frame and the closing element, the closure holder 1 has to be aligned. The closure holder 1 according to the invention permits simple and precise alignment. According to the invention, the frame does not have to be a separate element. The frame can also be formed by the edge of a wall or similar surrounding the opening.

(9) A mounted closure holder 1 is illustrated perspectively in FIG. 1. Said closure holder 1 is illustrated as an exploded illustration in FIG. 2, as a result of which the individual elements thereof can be seen better. The closure holder 1 has fastening regions 3.2 for fastening to or in a frame or a closing element. For the fastening, connecting means, not illustrated, such as, for example, screws or rivets, are plugged into fastening recesses 3.21 of the fastening regions 3.2 and connected to the frame, the closing element or an element arranged thereon.

(10) As can be seen, the closure holder 1 essentially comprises four elements: a basic element 3, a receiving element 4 and two actuating elements 5. However, a single actuating element 5 would also be sufficient for the distance adjustment according to the invention. Furthermore, the closure holder 1 can also comprise further elements in addition to the element shown. The elongate basic element 3 and the receiving element 4 which is substantially in the shape of a C profile preferably consist of injection molded plastic, but may also have metal elements, in particular in the region of the undercut 4.2, or may be completely composed of metal.

(11) The undercut 4.2 is arranged on the receiving element 4 and, in the mounted state, runs substantially parallel to the side 4.5 of the receiving element 4 lying opposite it along an actuating direction S which runs parallel to the actuating movement of the undercut 4.2. Together with the side 4.5, the undercut 4.2 surrounds a substantially empty space, in which the bolt element can engage for locking purposes. For this purpose, the bolt element engages the undercut 4.2 from behind, which prevents a movement of the bolt element, for releasing the opening, relative to the closure holder 1, in particular counter to the actuating direction S, until the lock is undone, for example by pivoting or pulling the bolt element away. The side 4.5 and the undercut 4.2 here form a region of the receiving element 4 with a C-shaped cross section. In order to be engaged from behind by the bolt element as securely as possible, that side 4.21 of the undercut which faces the bolt for locking purposes has a substantially W-shaped profile.

(12) Each of the actuating elements 5 together with a mating thread 3.1 and a bearing opening 4.1 forms an actuating device 2 with which the distance of the undercut 4.2 in relation to the basic element 3 can be adjusted. However, for the adjustment according to the invention of the distance of the undercut 4.2, a single actuating device 2 would also be sufficient, with the closure element 1 then essentially consisting of three elements.

(13) The actuating device 2 permits a movement of the undercut 4.2 in relation to the basic element 3 along the actuating direction S in the manner of a spindle drive by said actuating device moving the receiving element 4, which carries the undercut 4.2 and is adjustable together therewith, along the actuating direction S optionally toward the basic element 3 or away from the basic element 3. For this purpose, the actuating device 2 has a bearing opening 4.1 which is arranged on the receiving element 4 and is formed in particular integrally with the receiving element 4. The actuating element 5 is mounted on one side in the bearing opening 4.1. At its opposite end, the actuating element 5 interacts with the mating thread 3.1, which is fastened to the basic element 3. In order to change the distance between the basic element 3 and the undercut 4.2, the actuating element 5 is rotated about its longitudinal axis. This rotational movement is converted into a linear movement of the actuating element 5 by the interaction of the actuating element 5 with the mating thread 3.1. By means of this linear movement, the actuating element 5 together with the receiving element 4, which carries the actuating element 5 in a manner rotating freely in the bearing opening 4.1, is pulled toward the basic element 3 or pushed away from the latter depending on the direction of rotation. The distance is therefore adjusted in the manner of an elevating thread or a spindle drive, which is mounted on one side in the receiving element 4, with the basic element 3 as the spindle nut.

(14) Nevertheless, in the case of an actuating device 2 according to the invention, the bearing opening 4.1 can also be arranged on the basic element 3 and the mating thread 3.1 on the receiving element 4. It is also possible, in the case of an actuating device 2 according to the invention, for individual or a plurality of parts of the above-described actuating device 2 to be omitted.

(15) As can be seen in FIG. 1, the cylindrical actuating element 5 has a thread 5.1 which serves for connecting the actuating element 5 to the basic element 3. On the side lying diametrically opposite the thread 5.1, the actuating element 5 has a head 5.3 which forms the end of the actuating element 5. The head 5.3 has a larger radius than the thread 5.1 but can also be formed with the same radius as the thread 5.1. In addition, the head 5.3 comprises a drive region 5.4 which is designed in the manner of a hexagon socket. Alternatively, the drive region 5.4 can be designed in the form of a hexagon stub, hexalobular socket, slot or cross slot. The actuating element 5 is coupled via said drive region 5.4 to a drive device, not illustrated, such as, for example, a screwdriver or drill screwdriver, for driving the actuating movement. The actuating element 5 has overall a substantially screw-like geometry.

(16) For the arrangement on the receiving element 4, the actuating element 5 has a circumferential tapering with a groove 5.2. The groove 5.2 is bounded by the thread 5.1 and the head 5.3, but can nevertheless also be at a distance from said thread and head. The groove 5.2 permits a rotational, but axially fixed arrangement on the receiving element 4. For this purpose, the groove 5.2 is configured in the manner of a radius change abruptly springing back inward. This permits a form-fitting mounting of the groove 5.2 in the bearing opening 4.1. Push and pull forces can be transmitted from the actuating element 5 to the receiving element 4 in order to adjust the distance in relation to the basic element 3.

(17) FIG. 3 illustrates the receiving element 4 according to FIG. 1 in more detail. The bearing openings 4.1 are arranged on both sides of the undercut 4.2. By this means, the actuating devices 2 are arranged on either side of the undercut 4.2. In addition to the adjustment of the distance of the undercut 4.2 in relation to the basic element 3, the two actuating devices 2 also permit an inclination of the undercut 4.2. By means of the adjustable oblique position of the undercut 4.2, a distortion of the closing element and/or of the frame caused by manufacturing tolerances or caused by wear can be compensated for. Different distances between the undercut 4.2 and the basic element 3 can be set by means of the actuating devices 2, thus resulting in an inclination of the undercut 4.2 in relation to the basic element 3.

(18) As described above, the actuating element 5 of the actuating device 2 is mounted on a bearing opening 4.1 of the receiving element 4, said bearing opening likewise belonging to the actuating device 2. The bearing opening 4.1 has a bearing region 4.11 and a plug-in region 4.12. The plug-in region 4.12 is larger than the bearing region 4.11. This makes it possible to plug the actuating element 5, with the thread 5.1 and/or the head 5.3 in front, into the plug-in region 4.12. For this purpose, the inner radius of the plug-in region 4.12 is at least the same size as the outside diameter of the thread 5.1 and/or of the head 5.3 of the actuating element 5.

(19) By contrast, the bearing region 4.11 has an inside diameter below the outside diameter of the thread 5.1 and/or of the head 5.3 of the actuating element 5. This smaller inside diameter of the bearing region 4.11 prevents an actuating element 5 which is mounted in the bearing region 4.11 from being able to emerge from the bearing region 4.11 in the axial direction. An axial restriction of the movement freedom of the actuating element 5 is achieved. The radius of the bearing region 4.11 substantially corresponds to the outside diameter of the groove 5.2 of the actuating element 5. The axial dimension of the bearing region 4.11 likewise substantially corresponds to the axial length of the groove 5.2. The groove 5.2 can thereby be mounted in a form-fitting manner in the bearing region 4.11. The push and pull forces are thus transmitted from the actuating element 5 to the receiving element 4 in order to adjust the distance in relation to the basic element 3.

(20) The bearing region 4.11 and the plug-in region 4.12 form a keyhole-shaped bearing opening 4.1 in which the two substantially circular regions 4.11 and 4.12 are connected to each other via an elongated hole running between the two regions 4.11, 4.12. The smaller diameter of said elongated hole substantially corresponds here to the inside diameter of the bearing region 4.11.

(21) The basic element 3 illustrated in FIG. 1 will be described in more detail below with reference to the illustration in FIG. 4. It has a bar-shaped geometry of substantially lower height than length.

(22) Along its longitudinal axis, the center of the basic element 3 has an insertion region 3.5, into which the receiving element 4 is inserted for the mounting of the closure holder 1. The insertion region 3.5 is surrounded by a frame-like guide region 3.4 for guiding the actuating movement of the receiving element 4. Said guide region 3.4 interacts with a circumferential guide region 4.4 of the receiving element 4 illustrated in FIG. 3. The two guide regions 3.4, 4.4 together form a guide for guiding the actuating movement of the receiving element 4. For this purpose, they lie against one another with the contact surfaces 3.41, 4.41 in the manner of a sliding guide. The guide region 3.4 is formed in a complementary manner to the guide region 4.4 and receives the latter, which permits a form-fitting guidance of the movement of the receiving element 4. Closure forces acting transversely with respect to the actuating device 2 are transmitted from the receiving element 4 to the basic element 3 by means of the guide 3.4, 4.4. A disadvantageous action, in terms of the connection, upon the actuating device 2 and the actuating element 5 with said closure forces is prevented. The actuating devices 2 and in particular the actuating elements 5 lie to this extent outside the force flux.

(23) The guide region 4.4 and the bearing opening 4.1 are arranged with respect to each other in such a manner that, with the closure holder 1 fitted, with the guide region 4.4 lying against the guide region 3.4, the actuating element 5 which is secured via the mating thread 3.1 cannot be transferred from the bearing region 4.11 into the plug-in region 4.12. In the mounted state, an unintentional emerging of the actuating element 5 from the bearing opening 4.1 and therefore dismantling of the actuating device 2, and release of the receiving element 4 from the basic element 3, are prevented.

(24) In order to securely guide the receiving element 4, the basic element 3 furthermore has two rail-shaped guide structures 3.42. The latter are formed integrally with the guide region 3.4, wherein, according to the invention, the guide structures 3.42 can also be separate elements spaced apart from the guide region 3.4 and in particular a single guide structure 3.42. The guide structures 3.42 arranged in the manner of tracks engage in groove-shaped guide structures 4.42, formed in a complementary manner thereto, of the receiving element 4. By means of the engagement in the guide structures 4.42, the guide structures 3.42 lying next to one another on the same side of the basic element 3 permit secure guidance of the actuating movement in the manner of guide rails and guide grooves.

(25) The basic element 3 and the receiving element 4 are formed in the manner of interacting plug-in connection elements by means of the guide 3.4, 4.4. The basic element 3 partially surrounds the receiving element 4 by means of the guide region 3.4 along the section plane illustrated in FIG. 5.

(26) Two pins 3.3 protrude from that side of the basic element 3 which faces the receiving element 4. Said pins each bear a mating thread 3.1, which, as part of the actuating device 2, interacts with the thread 5.1 of the actuating element 5 for the connection of the latter. The mating thread 3.1 is in the form of an internal thread of a threaded bore. In order to connect the basic element 3 to the receiving element 4, the pins 3.3 are plugged into plug-in elements 4.3 of the receiving element 4. The plug-in elements 4.3 each bear the bearing openings 4.1 of the actuating devices 2. In particular in the case of a closure holder 1 according to the invention with just one actuating device 2, it is optionally possible also only to provide in each case one pin 3.3 and one plug-in element 4.3. The circumferential inner surface of the plug-in element 4.3 and the circumferential outer surface of the pin 3.3 additionally guide the actuating movement of the undercut 4.2. In addition, when a pin 3.3 is plugged into the plug-in element 4.3, the mating thread 3.1 and the bearing region 4.11 of the bearing opening 4.1 are aligned with one another.

(27) During the installation of the closure holder 1 and for the assembly of the actuating device 2, the actuating element 5 is first of all plugged into the plug-in region 4.12 of the receiving element 4 and displaced transversely with respect to the plug-in direction for the engagement of the groove 5.2 in the bearing region 4.11. The actuating element 5 which is mounted in the receiving element 4 is subsequently connected to the basic element 3 by means of the thread 5.1 and the mating thread 3.1. The receiving element 4 is inserted here or subsequently into the insertion region 3.5, with the guide regions 3.4, 4.4 and the guide structures 3.42, 4.42 engaging in one another in the manner of a plug-in connection. Alternatively, first of all an engagement of the thread 5.1 and of the mating thread 3.1 is produced and the receiving element 4 is subsequently plugged onto the actuating element 5 in such a manner that the actuating element 5 is plugged into the plug-in region 4.12. Subsequent thereto, the receiving element 4 is displaced in relation to the actuating element 5 and the basic element 3 in order to transfer the actuating element 5 into the bearing region 4.11. The second alternative requires the receiving element 4 to be spaced apart in relation to the basic element 3 via the actuating device 2 in such a manner that the guide regions 3.4, 4.4 do not lie against one another and the guide structures 3.42, 4.42 do not engage in one another.

(28) FIG. 5 and FIG. 6 show sectional views of the closure holder 1 according to FIG. 1 for differently adjusted distances of the undercut 4.2 with respect to the basic element 3. In FIG. 5, there is a smaller distance D1 between the basic element 3 and the receiving element 4. The guide regions 3.4 and 4.4 lie against one another with their contact surfaces 3.41, 4.41. The pin 3.3 engages in the plug-in element 4.3. Closure forces acting transversely with respect to the axis of the actuating element 5 can be transmitted by the receiving element 4 to the basic element 3 without having an effect on the actuating element 5.

(29) In order to change the distance D1 and therefore also to adjust the distance of the receiving element 4 in relation to the basic element 3, the actuating element 5 is rotated about its longitudinal axis in order to actuate the actuating device 2. By means of the interaction of the thread 5.1 and the mating thread 3.1, said rotational movement is converted into an axial longitudinal movement of the actuating element 5. A push or pull force exerted by the axial longitudinal movement is transmitted to the receiving element 4 by the above-described axial fixing of the actuating element 5. The receiving element 4 is moved away from the basic element 3 or toward the latter by means of the push or pull force and is guided here by the guide 3.4, 4.4. Said guide is additionally supported by the guide structures 3.42, 4.42 which are not illustrated in FIG. 5 and FIG. 6.

(30) In order to increase the distance D1 toward a distance D2, the actuating element 5 is rotated about its longitudinal axis, for example, counterclockwise. By this means, the actuating element 5 is unscrewed from the mating thread 3.1, which leads to a linear movement of the actuating element 5 together with the receiving element 4 and the undercut 4.2 counter to the actuating direction S. The actuating element 5 is rotated here until the greater distance D2 has been set.

(31) The use of the above-described closure holder 1 and of the method for adjustments of the closure holder 1 makes it possible to achieve a simpler and more precise alignment.
