Quarter-turn lock

The invention relates to sash locks with a housing part to be fastened to a door or another opening lock and a rotatable guide bolt, at the inner end of which a sash lug is fastened _{or the like}

Known quarter turn locks of this type are usually used with a normal key, e.g. a double-bit key, actuated. Often, however, it turns out to be necessary afterwards to equip the opening locks equipped with a cam lock, e.g. in electrical switch cabinets, with a Safety lock to be provided. To do this, the entire sash lock must be replaced in the known systems. "

The invention is based on the object of a sash lock of the aforementioned type so that it can be quickly and easily locked with a safety lock with simple means can be equipped.

«. 2 - '

According to the invention, this object is primarily achieved by solved that the sash lock for the inclusion of a security cylinder lock is set up and has a reducing sleeve to be inserted between the housing part and the cylinder lock is.

In this case, the reducing sleeve can have a shoulder to prevent rotation of the same relative to the housing part, which engages in a corresponding recess in the housing part «

P The reducing sleeve can also be in its outer end face have a cutout to limit the rotary movement of the cylinder lock when the security key is inserted

When using the cam lock for electrical control cabinets that protect against the ingress of moisture are and therefore have to comply with the VDE regulations for damp-proof systems, the invention proposes the guide bolt to be provided with at least one circumferential groove to accommodate O-ring seals.

For the same purpose, the cylinder lock can be in a section seated in the rear or inner housing part wall have a circumferential groove for receiving an O-ring seal.

The invention will now be described in more detail with reference to the drawing which shows it by way of example shows or show

Fig. 1 shows a gate driver lock in normal design, as it is used, for example, for doors of electric Schall3ohr-üi-uLeü. However, its application is not limited to such a safety barrier. The Yorreibverfall has a housing part 1, which is provided with an external thread 2 and with the help of a nut (not shown) in a corresponding recess of a door or the like. can be attached, the housing part 1 with an annular shoulder 3 or the like on the outer surface of the door. supports.

The housing part 1 has a large inner bore 4aif, which is coaxially aligned with a bore 5 in the rear or inner housing part wall 6 «, in the bores 4 and 5 sits in the embodiment according to FIG. 1, a guide pin 6, which is shown in FIGS. 2a, 2b and 2c is shown individually. This Guide pin 6 has a large cylindrical section 7 with an axial bore 8 and a continuous radial incision 9 on. A pin 10 stands up coaxially in the axial bore 8 and is inserted into the hollow shaft of an actuating key, not shown fits. In Fig. 2c, the cavity receiving the actuation key, consisting of 8 + 9, is clear - 10, recognizable. The large cylindrical section 7 of the guide pin 6 has a circumferential groove 11 for receiving a O-ring seal 12 (see Fig. 1), with which the Torreiberversehluß is sealed against the ingress of moisture into the cabinet or the like.

To the large cylindrical section 7 of the guide pin a short cylindrical section 13 connects to the rear or inside, which is inserted into the smaller bore 5 of the housing part 1 fits. The short cylindrical section 13 can be a Have circumferential groove 14 for an O-ring 15 (Fig. 1), which in a rear housing part wall 16 seals on a threaded section 17 of the guide bolt 6 becomes a sash lug with a nut 18 with the addition of a washer 19 20 attached, the rotational movement by a limiting pin ^ and a corresponding recess 22 on the housing part 1 to about 90 ° is limited. For the rotationally fixed coupling of the sash lug 20 to the threaded section 17, the latter has flattened areas 23 on.

Fig «, 3 shows a sash lock with a longitudinal section a security cylinder lock 24. The same housing part 1 can be used for this purpose. Instead of the guide pin 6 the cylinder lock 24 and a reducing sleeve 25 are used, which are shown in FIGS. 4a to 4c individually in three views is shown.

The cylinder lock 24 has a flange part 26. ) On the flange part 26 is a projection 27, which extends in the axial direction and to limit the rotational movement of the cylinder lock 24 with a corresponding cutout 28 cooperates in the outer end face of the reducing sleeve 25. The reducing sleeve 25 also has radial Incisions 29, in which the latches of the cylinder lock 24 engage when a key 30 is not inserted. For the non-rotatable fixing of the reducing sleeve 25 in the housing part 1 this has a projection 31 which is inserted into a corresponding recess 32 (e.g. hole) in the rear housing part wall 16 intervenes.

The sealing of the yoke seal according to 3? Ig · 3 takes place within the housing part wall 16 by the already mentioned O-ring seal 15. The other parts in FIG. 3, which correspond to those in Pig. 1 have the same reference numerals as in I ¹ Ig. 1.

The invention also relates to modifications of the enclosed Claim 1 outlined embodiment and relates above all also on all invention mertaale, which in the individually - or in combination - are disclosed throughout the description and drawing.
