DESCRIPTION OF PREFERRED EMBODIMENTS

[0037] The figures illustrate an exemplary embodiment of a locking trough according to the invention, also referred to as a floor recess plate. FIGS. 1 to 4 show a main body G of this locking trough.

[0038] The main body G consists preferably of metal, in particular of steel. It is formed in one piece. It has a cover plate 1, which has a through-opening 4 passing through it. The through-opening 4 is surrounded by a collar 3, which, when installed for use, projects downward. The cover plate 1 has fastening holes 2 passing right through it.

[0039] The cover plate 1 is configured to be substantially plane-parallel and as thin as possible. It serves for resting on a part of a building, in particular a floor region beneath a door leaf. It covers over a recess in the part of the building, wherein the through-opening 4 allows access to the recess and the collar 3 is directed toward the recess or even projects into it. The part of the building and the recess are not illustrated in the figures.

[0040] The through-opening 4 is arranged preferably eccentrically in the cover plate 1. However, it can also be arranged centrally. In this example, it is configured in the form of an elliptical slot. Other shapes and sizes, however, are also possible. In particular, it can also be of round configuration. Its size and shape are preferably tailored to the size and shape of the locking bolt which is intended to be inserted through it into the recess of the building.

[0041] The cover plate 1, and thus the main body G, can be fixed on the part of the building by virtue of the fastening holes 2. Screws are preferably used for this purpose. In order that the fastening holds to a sufficient extent even in the case of a very thin cover plate, the fastening holes in this exemplary embodiment are preferably provided with a countersink, which projects downward in the direction of the part of the building. The underside of the cover plate, however, can also be of plane-parallel configuration, and the fastening holes preferably have a countersink within the thickness of the plate.

[0042] In this example, the collar 3 fully encompasses the through-opening 4 and it is of closed configuration. It has anchoring elements, in this case in the form of holes 5. The holes 5 can be merely recesses or pass right through. They are preferably through-holes. In this example, the holes 5 extend along the long and short sides of the through-opening 4, but not in the curved transition regions thereof.

[0043] FIGS. 5 to 9 illustrate the complete locking trough according to the invention. It has the above-described main body G as well as a receiving pocket 6 for receiving the lowered locking bolt. The receiving pocket 6 is made of plastic material. It is preferably injection molded onto the collar 3. In this case, it completely encloses the collar 3 and also fills the holes 5.

[0044] As can clearly be seen in particular in FIG. 6, the plastic material of the receiving pocket 6 covers over an upper injection-molding surface 70 and a lower injection-molding surface 71. These injection-molding surfaces 70, 71 are formed by the main body G. The upper and/or the lower injection-molding surface 70, 71 are/is preferably inclined in relation to the plane of the cover plate 1. They project preferably into the through-opening 4. These injection-molding surfaces 70, 71 provide for enhanced bonding of the plastic material of the receiving pocket 6 to the main body G. The upper injection-molding surface 70, which is configured in the form of a step relative to the plate surface, provides for a flush transition of the plastic material of the receiving pocket 6 to the material on the upper side of the cover plate 1.

[0045] The upper and lower injection-molding surfaces 70, 71 run preferably all the way round the through-opening 4. These two injection-molding surfaces 70, 71 can likewise be manufactured by deep-drawing. They are also clearly discernible in FIGS. 3 and 4.

[0046] The shape of the receiving pocket 6 is tailored to the shape of the through-opening 4 or of the collar 3. As in this example, it preferably has a closed encircling lateral surface 60 as well as a downwardly terminating base 61.

[0047] The locking trough according to the invention can be manufactured cost-effectively, is stable and can be used with little noise being produced. By virtue of the plastic material being injection molded, it is also possible to manufacture receiving pockets which are smaller, and in particular narrower, than if they are deep-drawn from a metal.
