DETAILED DESCRIPTION OF THE DRAWINGS

[0038] Individual technical features of the exemplary embodiments described below may also be combined together with the above-described exemplary embodiments and the features of the independent claims and any further claims to form objects according to the invention. If expedient, elements which have the same function are provided with identical reference numerals.

[0039] According to FIG. 1, a belt lock according to the invention has two connecting pieces 1 which are partially arranged in one another and on one another as F-type connecting pieces (in plan view an F-shape is produced). The curved strips 2 connect one respective upper part 3 of one respective connecting piece 1 integrally to one respective lower part 4. On the inner face of the upper part 3 and the lower part 4 a belt adapter comprising two adapter plates 6 and 7 is assigned to each connecting piece, the connecting pieces being able to be arranged thereby on the respective belt ends, not shown.

[0040] The upper part 3 and the lower part 4 and the upper adapter plate 7 and the lower adapter plate 6 have recesses aligned with one another for arranging fastening means 8, 9 and 10. By means of the fastening means 8 and 9 the connecting pieces 1 are releasably connected to the belt adapter and/or the two adapter plates 6, 7 thereof.

[0041] The fastening means 8 in the present case is configured as a sleeve nut which may be countersunk in the upper part 3, the upper edge thereof running conically. Accordingly, the recess covered by the sleeve nut 8 also tapers. The fastening means 9 which is configured as a threaded screw is located in the thread of the sleeve nut 8.

[0042] In order to form a non-releasable connection between the belt end, not shown, and the belt adapter, fastening means 10 which are configured as rivets are used (FIG. 1).

[0043] In the exemplary embodiment according to FIGS. 2 and 3 only a part of a belt lock comprising the connecting piece 1 and a belt adapter is shown. In the present case, the connecting piece 1 is clamped against the adapter plate 7 by means of a clamping plate 11. The clamping plate 11 has recesses in which a fastening means 9, also configured as a threaded screw, is arranged, said fastening means nevertheless being able to be configured differently from the fastening means 9 in FIG. 1. The clamping plate 11 has on its lower face, not shown in FIG. 2, raised portions which engage in corresponding recesses of the upper part 3 and ensure an optimal fit of the clamping plate 11 on the connecting piece 1. Thus, on the one hand, the clamping plate 11 is used to ensure the releasable connection of the adapter plates 6 and 7 to the connecting piece 1 but at the same time a clamping is implemented thereby of the belt end, not shown, to be arranged between the adapter plates 6 and 7, and thus a securing of the adapter plates 6 and 7 to the belt end is also implemented thereby.

[0044] Additionally, both the upper adapter plate 7 and the lower adapter plate 6, not shown in the figure, comprise a series of tooth elements 12, resulting in the adapter plate 7, when fastened to the belt end, digging into the material of the belt. For example, the tooth elements 12 have been produced by stamping into the metal of the adapter plate 7 (FIG. 3).

[0045] Whilst in the upper adapter plate 7 the tooth elements 12 are arranged in the left-hand lower region shown in FIG. 4 and not in an angled-back upper region, the lower adapter plate 6 has the tooth elements 12 in the upper region adjacent to the adapter plate recesses 13 for passing through fastening elements. The action on the belt material is thus distributed over the region of the belt end in the longitudinal direction of the belt. Due to its upper angled-back portion, the upper adapter plate 7 is formed at the same time as a bar adapter plate, i.e. the offset of the right-hand upper end, which is provided with the adapter plate recess 13, is sufficiently great that a bar which is preferably configured as a screening bar may also be arranged at that point between the adapter plate 7 and the belt end.

[0046] The angled-back region of the lower adapter plate 6 is smaller in terms of shape. By means of an edge 14 the adapter plate is able to bear against a projection which rises only slightly over the thickness of the remaining material of the belt end (see FIG. 6) and thus produce an additional resistance against the belt adapter being pulled off the belt end.

[0047] Also to be seen in FIG. 4 is the shape of the clamping plate 11 which with its lower end forms a type of threaded sleeve which engages in the recess of the upper part 3.

[0048] The arrangement of a screening bar between the belt end 16 and upper adapter plate 7 of the belt adapter is shown in FIG. 5. Flattened end regions 17 of the respective screening bars 18 are arranged between the angled-back upper region of the adapter plate 7 and the belt end 16. Fastening means 10 in the form of rivets are able to fasten simultaneously the two adapter plates 6 and 7 and the screening bar 18 to the belt in one working step in a riveting machine. Both the simple replacement of the connecting pieces 1 and the use of a bar end 19 of a screening bar 20 as a lock pin are readily possible by means of the releasable fastening means 8 and 9. In the case of wear of the hinge region of the connecting piece 1, this relatively useful part may be simply manually released and replaced. In order to avoid protruding nuts, the fastening means 8, which is configured as a threaded sleeve, has indentations 21 on the outer face for securing the torque applied for the screw connection.

[0049] It may be seen, in particular, in FIG. 6 that a downwardly thickened and projection-like region of the belt end 16 bears against the edge 14 of the lower adapter plate 6. One end 22 of the adapter plate 6 leading away from the belt end is configured to be curved in order to avoid rubbing of the material and to protect the belt end, with the circulation of the belt and thus the flexion associated therewith in the deflection regions.

[0050] The curved strips 2 are adapted in terms of the curvature thereof to the radius of the bar end 19 of the screening bar 20 so that additional bushings no longer have to be used.

[0051] According to the exemplary embodiment according to FIG. 7, instead of rivets as fastening means 10, screws may also be used for securing a screening bar 18 to the belt, said screws preferably being countersunk in the upper adapter plates 7 and on the lower face, not shown in the figures, being screwed to mating parts, for example in the form of countersunk sleeve nuts or threaded plates.
