DETAILED DESCRIPTION

[0057] In order to fix a door 11 in relation to a door frame 12 such that the door 11 cannot be opened, a lock 14 with a frame-side locking holder 10 and a door-side locking latch 7 is provided, see FIG. 7. The locking latch 7 is rotatably mounted in a latch housing 15 and can be rotated to and fro between a locking position V and an unlocking position E. In the locking position V, the locking latch 7 engages in the locking holder 10 such that the door 11 is fixed relative to the frame 12 and can no longer be opened. In order to open the door 11, the locking latch 7 must first be rotated back again into an unlocking position E, in which the locking latch 7 no longer engages in the locking holder 10. The rotation of the locking latch 7 from the locking position V into the unlocking position E will be explained in more detail below with reference to FIGS. 14a to d.

[0058] First of all, the configuration of the locking holder 10 will now be described with reference to the illustration in FIG. 1. The locking holder 10 has a mounting element 1 which is configured in the manner of a base plate and via which the locking holder 10 can be connected to the frame 12 of a door 11. For this purpose, the elongate mounting element 1 has a bore in the form of a slot on each side, via which the mounting element 1 can be screwed to the door frame 12. Owing to the configuration as a slot, the mounting element 1 can still be displaced within certain limits, even if it is already connected to the frame 12 by screws, as long as the screws are not yet tightened. After the alignment of the mounting element 1, the screws are then tightened, and therefore a substantial movement of the mounting element 1 relative to the frame 12 is then no longer possible. The locking holder 10 can thus be fastened to the door frame 12 in a mounting plane M via the mounting element 1. The mounting plane M then also corresponds to the plane of the surface of the door frame 12, on which the locking holder 10 is mounted.

[0059] Furthermore, the locking holder 10 has a holding element 2, which is connected to it via two supports 1.1. Since the two supports 1.1 are at the same height and are arranged perpendicularly on the mounting element 1, the holding element 2 extends substantially parallel to the mounting element 1 or to the mounting plane M.

[0060] To lock the door 11, the locking latch 7 is now rotated into the intermediate space between the mounting plane M or the mounting element and the holding element 2 such that the locking latch 7 can no longer be moved in the vertical direction with respect to the mounting plane M and the door 11 is fixed relative to the frame 12. The position of the holding element 2 or the distance between the holding element 2 and the mounting plane M thus defines the closed position of the door 11.

[0061] A door seal is arranged between the door 11 and the frame 12, but this is not shown in the figures. Said door seal is compressed in the closed position of the door 11 such that the door 11 does not rattle and is not movable in the closed position. In addition, the seal can also ensure that gas exchange between the interior and the exterior is prevented or at least reduced. Owing to the compression of the seal, the latter exerts at least a certain force on the door 11 in the direction of the open position and thus presses the locking latch 7 from the direction of the mounting element 1 onto the holding element 2. The side of the holding element 2 which faces the mounting plane M then acts as a holding surface 3 on which the locking latch 7 rests in the locked position.

[0062] A holding shoe 5 is also provided in order to compensate for manufacturing tolerances or possibly also signs of aging of the seals. The function and the configuration of the holding shoe 5 will be described in more detail below, in particular with regard to FIGS. 1 to 6. First of all, however, it will firstly be described with reference to FIGS. 7 to 14d how a door 11 is intended to be converted, for example from a left-hand stop to a right-hand stop.

[0063] A door 11 hinged on the left can be seen, for example, in the illustration on the left in FIG. 7. The door 11 has a lock 14 which fixes the door 11 in the locking position V relative to the frame 12 such that the door 11 can then no longer be opened. The corresponding lock 14 has a rotatable locking latch 7 and a locking holder 10, as has already been described above. The middle and the right-hand illustration of FIG. 7 now illustrate how the door 11 hinged on the left can be converted such that it is then hinged on the right.

[0064] First of all, for this purpose, the door 11 is completely released from the frame 12 and then rotated through 180 degrees. In doing so, the frame-side elements of the lock 14 must be released from the right-hand side of the frame 12 and then reassembled on the left-hand side of the frame 12. The same can also apply to the door hinges. If the door 11 has then been rotated through 180 degrees and fastened to the frame 12 again, it can be opened again, closed and also locked again via the lock 14. However, as is evident from a comparison of the right and middle illustrations in FIG. 7, when the door 11 is turned around, the orientation of the handle lever 13 also changes. This is because it now no longer points downward but rather upward, which is generally not desired. It will now be described below how the lock 14 can be converted without having to dismantle it or the handle lever 11.

[0065] A first embodiment will first be described with reference to FIGS. 8a, b and 9a, b. FIGS. 8a, b show the latch housing 15 with the handle lever 13 arranged thereon, which is rotatably coupled to the locking latch 7 on the inside of the latch housing 15. The latch housing 15 has two stop receptacles 8, 9 which are configured as insertion openings and into which the stop 6 configured as a stop pin is selectively insertable. The inner workings of the latch housing 15 can be seen in FIGS. 9a and 9b. By positioning the stop 6 in the various stop receptacles 8, 9, a movement of the locking latch 7 can therefore be limited in different ranges of rotation.

[0066] The locking latch 7 is shown in a locking position V in FIG. 9a. The locking holder 10 is not shown. The locking latch 7 is configured as a double locking latch and has two mutually opposite latch elements 7.1 and 7.2. In the position according to FIG. 9a, the latch element 7.2 firstly rests against the stop 6 in the stop receptacle 9 such that the locking latch 7 can only be rotated clockwise, but not counterclockwise, since the stop 6 prevents this rotational movement. If the locking latch 7 is now turned clockwise, the latch element 7.2 is pivoted out of the locking holder 10 (not shown) and the door 11 can be opened. The locking latch 7 can be rotated until the latch element 7.1 rests against the other side of the stop 6. The stop 6 thus prevents the handle lever 13 and thus also the locking latch 7 from being rotated to an extent such that the latch element 7.1 engages in the locking holder 10.

[0067] In the illustration of FIG. 9b, the stop 6 is inserted into the other stop receptacle 8. From this position, the locking latch 7 can now only be turned counterclockwise, and specifically only until the latch element 7.1 strikes against the right-hand side of the stop 6. Although the locking latch 7 is configured as a double locking latch in the illustrations of FIGS. 9a and 9b, the device also works to the same extent with locking latches 7 that have only one latch element 7.1. The only difference then is that the handle lever 13 can be pivoted by approximately 180 degrees further than in the embodiment with a double locking latch.

[0068] In order now to convert the door 11, for example, from a left-hand door stop to a right-hand door stop, the stop 6 must first be pulled out of the respective stop receptacle 8, 9. The handle lever 13 and the locking latch 7 can then be rotated freely such that the handle lever 13 can be rotated into the desired downwardly pointing position, as can be seen in the right-hand illustration in FIG. 7. In a next step, the stop 6 can then be inserted into the appropriate stop receptacle 8 or 9 and the holes arranged on the outside of the latch housing 15 can be closed, for example using caps.

[0069] As an alternative to the arrangement of the stop receptacles 8, 9 or the stop 6 on the latch housing 15, the stop receptacles 8, 9 can also be arranged on the locking holder 10. In this embodiment, the outside of the latch housing 15 no longer has to have insertion openings for the stop 6. This embodiment will be described below first of all with reference to the illustration in FIGS. 11 and 12. As can be seen in particular in FIG. 11, the locking holder 10 has two stop receptacles 8, 9 which are arranged on different sides of the locking holder 10 and which are substantially arranged between the mounting element 1 and the holding element 2. Both the holding element 2 and the mounting element 1 have two recesses 8.1, 9.1 for each of the two stop receptacles 8, 9, which recesses extend in the manner of slots into the mounting element 1 and into the holding element 2 in the mounting direction MR. In this embodiment, the stop 6 has a total of four guide elements 6.3 which are configured in the manner of pins or bolts and which are guided in the recesses 8.1, 9.1 when the stop 6 is inserted into the respective stop receptacle 8, 9. The stop 6 is thus insertable either into the stop receptacle 8 or into the stop receptacle 9 in the mounting direction MR and can accordingly also be removed again from the stop receptacles 8, 9.

[0070] The holding shoe 5 is used to fasten the stop 6 to the locking holder 10 and thus has a dual function. This is because the holding shoe 5 serves not only to adjust the distance A1, A2 of the holding surface 3 from the mounting plane M, but also serves to secure the stop 6 in the corresponding stop receptacle 8, 9 of the locking holder 10. As described in more detail below, the holding shoe 5 can be latched to the holding element 2 and/or to the supports 1.1. In this latching position, the receptacles 5.4 arranged between the spring arms 5.3 and the limbs 5.1, 5.2 grip the two upper guide elements 6.3 of the stop 6 and thus hold them in the recesses 8.1, 9.1 of the respective stop receptacle 8, 9. The stop 6 is then received in a form-fitting manner between the holding shoe 5 and the mounting element 1 and the holding element 2. Furthermore, the stop receptacles 8, 9 also have a contact surface 8.2, 9.2, which are each part of one of the supports 1.1. Said contact surfaces 8.2, 9.2 serve as an additional support and thus ensure that the forces acting on the guide elements 6.3 are reduced, in particular when the locking latch 7 strikes against the stop 6. The sectional view of FIG. 12 once again shows how the guide elements 6.3 are received in the mounting receptacle 1, the holding element 2 and the holding shoe 5. The holding shoe 5 gripping the holding element 2 presses the guide element 6.3 both above and below the holding element 2 into the corresponding recess 8.1, 9.1 of the respective stop receptacle 8, 9 and then ensures, when it is latched to the holding element 2 or to the supports 1.1, that the stop 5 is held securely in the corresponding stop receptacle 8, 9.

[0071] Furthermore, it can be seen in particular in FIG. 11 that the stop 6 has two offsets 6.4 at the upper end. When the stop 6 is held by the holding shoe 5 in the stop receptacle 8, 9, the lower spring element 5.3 located on the side of the stop receptacle 8, 9 used lies in the offset 6.4, which faces toward the center of the locking holder 10. The offset 6.4 thus ensures that the corresponding guide element 6.3 can also be gripped by the lower receptacle 5.4 below the holding element 2. This can also be seen in the illustration of FIG. 2, in which the stop 6 is arranged in the right-hand stop receptacle 9. If the stop 6 is arranged in the left-hand stop receptacle 8, the holding shoe 5 grips the corresponding other guide element 6.3 of the stop 6.

[0072] A further embodiment of the stop 6 and the stop receptacles 8, 9 will now be described below with reference to the illustrations in FIGS. 10a to 10d. In this embodiment, the holding shoe 5 is longer than the holding shoe 5 shown in FIGS. 2 and 11, and the holding shoe 5 in this embodiment also has only two spring arms 5.3 and not four spring arms 5.3. The stop 5 also differs from the stop 5 described above in that it has only two guide elements 6.3 and the stop receptacles 8, 9 accordingly likewise have only two recesses 8.1, 9.1, one in the mounting element 1 and one in the holding element 2. The mounting element 1 and the holding element 2 are therefore more stable in this configuration.

[0073] The holding shoe 5 likewise has a receptacle 5.4 arranged between the spring arms 5.3 and the limbs 5.1, 5.2. In this embodiment, however, the receptacle 5.4 does not serve to hold the guide elements 6.3 in the respective recess 8.1, 9.1, but rather also to grip the supports 1.1 laterally in the manner of a clamp, as already described with regard to the holding element 5. In contrast to the embodiment with the four recesses 8.1, 9.1 per stop receptacle 8, 9, the contact surface 8.2, 9.2 is of greater importance in this embodiment. This is because the contact surface 8.2, 9.2 ensures that the stop 6 does not rotate when the locking latch 7 strikes against it. A corresponding sectional view through the stop 6 and the locking holder 10 is shown in FIG. 13.

[0074] As can also be seen in FIGS. 10a to 10d, the stop 6 can be switched to and fro between the two stop receptacles 8, 9 as desired. In the illustration of FIG. 10a, the stop 6 is initially in the first stop position P1 in the stop receptacle 8. After the holding shoe 5 has been removed from the holding element 2, the stop 6 can be removed from the stop receptacle 8 by hand, rotated through 180 degrees and then inserted into the stop receptacle 9. Finally, the holding shoe 5 is pushed back onto the holding element 2 in order to secure the stop 6 in the stop receptacle 9. This position is shown in FIG. 10d.

[0075] The unlocking of the lock 14 will now be explained in more detail below with reference to FIGS. 14a to 14d. In the position shown in FIG. 14a, the lock 14 or the locking latch 7 is in the locking position V. The stop 5 is arranged on the locking holder 10 and is inserted in the stop receptacle 9 in the stop position P1. In the locking position V, the latch element 7.1 of the locking latch 7 rests against a locking stop surface 6.1. This stop surface 6.1 can also be seen in FIG. 11, for example. This is the stop surface 6.1 against which the locking latch 7 rests in the locking position V. Depending on the stop position P1, P2, this locking stop surface 6.1 is arranged either on the left or right of the stop 6 and always faces toward the center of the locking holder 10.

[0076] For unlocking purposes, the locking latch 7 must now be rotated clockwise, as indicated by an arrow in FIG. 14a. During this rotational movement, it passes through the positions shown in FIGS. 14b and c. As soon as the latch element 7.1 has then been pivoted out of the locking holder 10 and the latch element 7.1 no longer engages behind the holding surface 3 of the locking holder 10, the door 11 can be opened. This unlocking position E is shown in FIG. 14d. It can be seen that, in this position, the latch element 7.2 strikes against the stop 6 or against the unlocking stop surface 6.2 and, as a result, further rotation of the locking latch 7 in the unlocking direction is no longer possible. The unlocking stop surface 6.2 can also be seen in the illustration of FIG. 11.

[0077] If the stop 6 is now pulled out of the stop receptacle 9 and inserted into the stop receptacle 8, a different stop pattern results. Starting from the position in FIG. 14d, the locking latch 7 is then rotatable further in the clockwise direction until the latch end 7.2 then strikes against the stop 6 located in the stop position P1. In this locking position V, the latch element 7.2 then rests against the locking stop surface 6.1 of the stop. However, the locking stop surface 6.1 is not the same surface against which the latch element 7.1 strikes when the stop 6 is in the stop position P1, as has been described above, but rather the locking stop surface 6.1 lies opposite this surface, as this can also be seen with reference to FIG. 11, for example. If the locking latch 7 is then rotated counterclockwise from this position into the unlocking position E, the latch element 7.1 strikes against the unlocking stop surface 6.2 of the stop 6 and thus limits further rotation of the locking latch 7.

[0078] By repositioning the stop 6 between the two stop receptacles 8, 9, the rotational movement of the locking latch 7 can thus be controlled. Since, depending on the stop position, the latch element 7.2 and the latch element 7.1 engage behind the holding surface 3 of the locking holder 10 and the locking holder 10 is connected to the handle lever 13, the position of the handle lever 13 can then also be adjusted in the locking position V and the unlocking position E.

[0079] The holding shoe 5 fulfills a dual function and serves to secure the stop 6 in the stop receptacles 8.9, but at the same time the distance between the holding surface 3 and the mounting plane M can also be adjusted via the holding shoe 5. The function and the configuration of the holding shoe 5 with regard to the distance adjustment will now be explained in more detail below with regard to FIGS. 1 to 6.

[0080] A door seal is arranged between the door 11 and the frame 12, but this is not shown in the figures. Said door seal is compressed in the closed position of the door 11 such that the door 11 does not rattle and is not movable in the closed position. In addition, the seal can also ensure that gas exchange between the interior and the exterior is prevented or at least reduced. Owing to the compression of the seal, the latter exerts at least a certain force on the door 11 in the direction of the open position and thus presses the locking latch 7 from the direction of the mounting element 1 onto the holding element 2. The side of the holding element 2 which faces the mounting plane M then acts as a holding surface 3 on which the locking latch 7 rests in the locked position.

[0081] A holding shoe 5 is also provided in order to compensate for manufacturing tolerances or possibly also signs of aging of the seals. The function and the configuration of the holding shoe 5 will now be described in more detail below, in particular with regard to FIGS. 1 to 6.

[0082] The holding shoe 5 is releasably connected to the holding element 2 and can be pushed onto the holding element 2 from the front in a mounting direction MR oriented parallel to the mounting plane M. The intermediate space located between the holding element 2 and the mounting element 1 is reduced by the holding shoe 5, which correspondingly also leads to a displacement of the holding surface 3 in the direction of the mounting plane M. The holding shoe 5 thus leads to the locking latch 1 being located closer to the mounting plane M and thus also closer to the door frame 12 in the locking position V. Accordingly, the door 11 is then also pressed more strongly against the seal in the closed position. As can also be seen, it is not required to connect the holding shoe 5 to the holding element 2 using a tool, but rather the holding shoe can simply be pushed onto the holding element 2 by hand and it then automatically latches to the holding element 2 and/or to the supports 1.1, which will be described in more detail below.

[0083] The holding shoe 5 can be connected to the holding element 2 in two different mounting positions M1, M2. The mounting position M1 is shown in the sectional view of FIG. 3 and the mounting position M2 in the sectional view of FIG. 4. It can also be seen that the holding shoe 5 comprises two limbs 5.1 and 5.2, which have a different thickness. The limb 5.1 is significantly thinner than the limb 5.2 and is only about half the thickness of the limb 5.2. Both the illustration of FIG. 3 and that of FIG. 4 involve the same holding shoe 5 in different mounting positions M1, M2. The holding shoe 5 is accordingly pushed onto the holding element 2 in such a way that the thicker limb 5.2 faces the mounting plane M, and the other way around such that the thinner limb 5.1 faces the mounting plane M. The holding shoe 5 was therefore accordingly rotated once by 180 degrees.

[0084] Furthermore, it can be seen that, because of the different limb thicknesses, the distance A1, A2 of the holding surface 3 to the mounting plane M is different in each mounting position M1, M2. The holding surface 3 refers in each case to the surface of the limb 5.1, 5.2 against which the locking latch 7 rests in the locked position, i.e. in each case that surface of the holding shoe 5 which faces the mounting plane M. Owing to the fact that the thicker limb 5.2 faces the mounting plane M in the mounting position M1, the distance A1 of the holding surface 3 relative to the mounting plane M is correspondingly also smaller than in the second mounting position M2. This also becomes clear when comparing the two distances A1 and A2 in the different mounting positions M1 and M2 which are shown in FIGS. 3 and 4. The holding shoe 5 thus creates the possibility of adjusting the distance between the holding surface 3 and the mounting plane M in three different steps. If no holding shoe 5 is used, the distance is at its largest and the locking latch 7 engages behind the holding element 2 in the locking position V and then rests against it. If the holding shoe 5 is used in the first mounting position M1, the distance is reduced to the distance A1, and, if the holding shoe 5 is used in the second mounting position M2, the distance is reduced even further to the distance A2.

[0085] FIGS. 5 and 6 now show two differently configured holding shoes 5. The holding shoe 5 according to FIG. 5 corresponds to that which is also shown in FIGS. 1 and 2. The two limbs 5.1, 5.2 are parallel to one another and grip the holding element 2 in the pushed-on position. So that the holding element 5 can be pushed onto the holding element 2 as reliably as possible, the holding element 2 has a guide 2.1 which consists of two parallel webs, as can be seen in the illustration in FIG. 1. In the pushed-on position, the holding shoe 5 then lies between these two webs, which insofar serve as a linear guide.

[0086] So that the holding shoe 5 is also reliably held on the holding element 2 when the locking latch 7 is moved into the unlocking position E and thereby slides onto the holding shoe 5, the holding shoe 5 has four spring arms 5.3, one of which is located on each side of the two limbs 5.1, 5.2. So that the spring arms 5.3 can latch to the holding element 2, each spring arm 5 has a latching lug, of which two then grip behind the holding element 2, depending on the mounting position M1, M2 of the holding shoe 5, as can be seen in the illustration of FIGS. 3 and 4. The latching lugs of all four spring arms 5.3 point in the same direction. Furthermore, the holding shoe 5 has receptacles 5.4 which extend between the spring arms 5.3 and the limbs 5.1, 5.2 and which can be clearly seen in the illustration in FIG. 1. The function of these receptacles 5.4 has already been discussed in more detail above with regard to the stop 6.

[0087] FIG. 6 shows the holding shoe 5 in a second embodiment. The limbs 5.1, 5.2 of this embodiment also extend parallel to one another and grip the holding element 2 from above and from below. In contrast to the holding shoe 5 according to FIG. 5, however, in this embodiment the holding shoe 5 has only two spring arms 5.3, which extend over the entire height of the holding shoe 5. This holding shoe 5 is also longer, and therefore it can grip the entire holding element 2 with the spring arms 5.2, as can be seen in the illustrations of FIGS. 10a and 10b. Since this holding shoe 5, as it is being pushed on, is guided over the spring arms 5.3 lying laterally on the holding element 5 or on the supports 1.1, an additional guide 2.1 is not absolutely necessary on the holding element 2 in this embodiment.

[0088] Furthermore, it can be seen in FIGS. 10a and 10b that the two spring arms 5.3 each have a latching lug, said latching lugs facing one another. Said latching lugs grip the holding element 2 or the supports 1.1 and then ensure, in a manner entirely analogous to the spring arms 5.3 described with regard to the configuration according to FIG. 5, that the holding shoe 5 is held securely on the holding element 2. Furthermore, in this embodiment, the holding element 2 has notches in the upper end region, in which the latching lugs of the spring arms 5.3 can engage. The corresponding notches can be seen, for example, in FIG. 10b.

[0089] With regard to the choice of material for the holding shoe 5, materials that have good sliding properties have proven to be particularly advantageous in practice. There are essentially two reasons for this. The locking latches 7 have to have a high level of strength and are therefore as a rule made of metal and, to prevent corrosion, mostly made of galvanized metal. Since the locking latch 7, as it engages behind the holding surface 3, now slides on this surface, the galvanized surface of the locking latch 7 may be abraded, which is then associated with an increased risk of corrosion. If the holding shoe 5 and in particular the corresponding surfaces of the holding shoe 5, on which the locking latch 7 slides, have good sliding properties, this reduces the risk of material abrasion.

[0090] In addition, if the locking latch 7 presses too hard on the holding surface 3, the holding shoe 5 may also entrain the holding shoe 5, when the locking latch 7 is rotated into the unlocking position E, and thus pulls it from the holding element 2. In this respect, good sliding properties also allow the holding shoe 5 to be able to be held securely on the holding element 2. Possible materials for the holding shoe 5 are, for example, plastic, in particular POM, brass or bronze. Furthermore, surface coatings can also be used to improve the sliding properties.
