DETAILED DESCRIPTION
[0045] 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
[0046] First of all, the configuration of the locking holder 10 will now be described with reference to the illustration in
[0047] 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.
[0048] 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.
[0049] 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.
[0050] 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
[0051] The holding shoe 5 is connected releasably to the holding element 2, and can be pushed onto the holding element 2 from the front in a mounting direction MR which is oriented parallel to the mounting plane M. The intermediate space which is situated between the holding element 2 and the mounting element 1 is decreased in size by way of 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 therefore leads to the locking latch 1 being situated in the locking position V closer to the mounting plane M and therefore also closer to the door frame 12. Accordingly, the door 11 is also pressed onto the seal to a more pronounced extent in the closed position. As can be seen, furthermore, it is not necessary for the holding shoe 5 to be connected to the holding element 2 by means of a tool, but rather the holding shoe can simply be plugged onto the holding element 2 by hand and it then latches automatically to the holding element 2 and/or to the supports 1.1, which will be described in greater detail below.
[0052] The holding shoe 5 can be connected in two different mounting positions M1, M2 to the holding element 2. The mounting position M1 is shown in the sectional view of
[0053] It can be seen, furthermore, that the distance A1, A2 of the holding surface 3 from the mounting plane M is also different in each mounting position M1, M2 as a result of the different limb thicknesses. The holding surface 3 in each case denotes that surface of the limb 5.1, 5.2, against which the locking latch 7 bears in the locked position, that is to say in each case that surface of the holding shoe 5 which faces the mounting plane M. By virtue of 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 with respect to the mounting plane M is correspondingly also smaller than in the second mounting position M2. This also becomes clear in the case of a comparison of the two distances A1 and A2 in the different mounting positions M1 and M2 which are shown in
[0054]
[0055] In order that the holding shoe 5 is held reliably on the holding element 2 even when the locking latch 7 is moved into the unlocking position E and in the process slides on the holding shoe 5, the holding shoe 5 has four spring arms 5.3, of which in each case one is situated on each side of the two limbs 5.1, 5.2. In order that the spring arms 5.3 can latch to the holding element 2, each spring arm 5 has a latching lug, of which, depending on the mounting position M1, M2 of the holding shoe 5, in each case two then engage behind the holding element 2, as can be seen in the illustration of
[0056]
[0057] Furthermore, it can be seen in
[0058] With regard to the material selection for the holding shoe 5, materials of the type which have satisfactory sliding properties have proven to be particularly advantageous in practice. This essentially has two reasons. The locking latches 7 have to have a high strength, and are therefore as a rule made from metal and, in order to prevent corrosion, usually from galvanized metal. Since the locking latch 7 then slides on this surface when engaging behind the holding surface 3, it can possibly occur that the galvanized surface of the locking latches 7 is abraded, which is then accompanied by 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 satisfactory sliding properties, the risk of material abrasion decreases as a result.
[0059] Moreover, it can also occur that, in the case of an excessively high pressure of the locking latch 7 on the holding surface 3, the holding shoe 5 also moves the holding shoe 5 in the case of a rotation of the locking latch 7 into the unlocking position E, and therefore pulls this holding shoe 5 from the holding element 2. To this extent, satisfactory sliding properties also make it possible that the holding shoe 5 can 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.
[0060] Even if the distance A1, A2 between the holding surface 3 and the mounting plane M and, via this, also the closing position of the door 11 with respect to the frame 12 can be set by way of the holding shoe 5, a problem arises, furthermore, if the door 11 is to be modified, for example from a left-hand stop to a right-hand stop.
[0061] A door 11 hinged on the left can be seen, for example, in the illustration on the left in
[0062] 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
[0063] A first embodiment will first be described with reference to
[0064] The locking latch 7 is shown in a locking position V in
[0065] In the illustration of
[0066] 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
[0067] 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
[0068] 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 has already been described above, 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 additionally 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
[0069] Furthermore, it can be seen in particular in
[0070] A further embodiment of the stop 6 and the stop receptacles 8, 9 will now be described below with reference to the illustrations in
[0071] 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
[0072] As can also be seen in
[0073] The unlocking of the lock 14 will now be explained in more detail below with reference to
[0074] For unlocking purposes, the locking latch 7 must now be rotated clockwise, as indicated by an arrow in
[0075] 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
[0076] 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 thus also be adjusted in the locking position V and the unlocking position E.
