Abstract

The fastening dowel arrangement is used in key-operated rotating bar locks. This lock has a central mandrel and projecting rotating locking bars with end claws. All dowel holes and key hole bore are drilled by a simple multi-spindle drilling machine in one operation. The centre points of all fastening dowels are arranged on a centre line passing vertically through the central key mandrel or central keyhole. The dowels are used for a lock housing for the rotating hook and rotating bar bearings. Fastening dowels on the lock housing are symmetrical to the key mandrel or key hole relative to this centre line. Fastening dowels on the lock housing can be replaced by a central fastening dowel.

Description

The invention relates to a fastening dowel arrangement for a beard key-operated espagnolette lock according to the preamble of claim 1.

Such a fastening dowel arrangement is from the catalog: Der Große Häfele, N agold 1971, page 2.18 and 2.30, known, with a Zentralbefestigungsdübei for the lock housing outside the center line of the other fastening dowels is provided in the known fastening dowel arrangements are either the fastening dowels for the lock housing or the fastening dowels for the rod bearings and the swivel hook bearings are asymmetrical to the central keyhole or central key pin. In addition, there are the fastening dowels for the rod bearings not in line with the lock body mounting dowels and the keyhole. At a Another lock housing fastening dowel arrangement are the fastening dowels for the lock housing Arranged symmetrically to the keyhole or key pin, but off-center from the key pin center line (DE-GM 19 95 425).

In all these fastening dowel arrangements, however, there is the major disadvantage that for the production the drill holes in the door wood for attaching the fastening dowels and the keyhole hole either requires intricate and expensive drilling tools or multiple additional drilling operations, whereby the installation of the necessary holes is not insignificantly expensive.

The object of the invention is to provide a fastening dowel arrangement for an espagnolette lock to create the prerequisite type, in which the drill holes for all fastening dowels and the Keyhole drilling in the door wood using a simply designed multi-spindle drill in one operation can be drilled.

This object is achieved by the features of the characterizing part of claim 1.

This arrangement of the fastening dowels and keyhole drilling has the advantage that their drill holes in the door wood with a simply constructed multi-spindle drill in the shortest possible time Time can be produced efficiently.

Claim 2 includes an advantageous hamlet formation of the subject matter of claim 1.

In the drawing, two exemplary embodiments are shown, namely shows

Fig. 1 is a rear view of the mounting dowel assembly for a espagnolette lock with swivel bar and swivel hook bearing and central keyhole,

FIG. 2 is a view of the lock housing like FIG. 1 with central key pin and

3 shows a view against the faceplate of the espagnolette lock according to FIG. 1.

The espagnolette lock on which the application is based is for the sake of better clarity the set up is not shown.

In the lock housing 1 according to FIG. 1 is the central keyhole 2 at the intersection of the Center line of the lock bolt 3 and the fastening dowel 4, whereas in the case of the lock housing according to FIG. 2 the (central) key pin 5 at the point of intersection: the center lines of the lock bolt 3 and the fastening dowel 4 lies. On the center line of the fastening dowels 4 are also the fastening dowels! 6 for the pivot rod bearings 7 and the fastening dowels 8 for the rotary hook bearing 9 are arranged.

Instead of fastening the lock housing 1 by means of two eccentrically arranged fastening dowels 4 zn, can do the same thing, as indicated by dotted lines in FIGS. 1 and 3, by a point at the intersection of the Center lines arranged central fastening dowels 10 are attached.
