door

The invention relates to a right and left by upside-down positions usable door with a related on the latch bolt axis symmetrically designed latch bolt lock, which in each of the two mounting positions the door responds equally to the twisting of a handle that can be inserted into it in the usual sense.

Such a door has already been proposed in German patent application P 16 59.955.6-25. This already proposed. The door has only a single push-button nut on; a locking device is not provided.

cλ α ο 11 /

The invention is based on the object of designing a door of the type already proposed in such a way that that the user, no matter what position the door occupies, the usual assignment of door handle and Finds a keyhole or cylinder lock.

To solve this problem, the invention proposes that the lock be symmetrical to the latch bolt axis two follower nuts and two keyholes or attachment points between the presser nuts for cylinder locks are arranged, of which the lower or the upper handle follower is assigned that the door for each follower / keyhole or cylinder lock attachment point pair a pairing of a handle follower hole and a passage opening for a key or has a cylinder lock and that each, unused pairing by an upside-down position the door to be turned cover plate is covered, which has only one opening to carry out a Has handle follower axis and a passage opening for a key or a cylinder lock. Despite the symmetrical doubling, the usual distance between the door according to the invention can be Door handle and keyhole or cylinder lock with small overall dimensions of the latch bolt lock Achieve perpendicular to the latch bolt axis, because between each door handle and the associated keyhole or cylinder lock to be observed, from the usual Locks partially overlap given distances and therefore do not add up completely.

The accompanying figures explain a lock intended for a door according to the invention. Put it dar:

FIG. 1 shows a lock according to the invention with the closure cover removed;

FIG. 2 shows a slide element in plan view;

FIG. 3 shows a further slide element in plan view;

FIG. 4 shows a release template in plan view;

Figure 5 is a plan view of the bottom of the lock housing and the latch.

In Fig. 1, the door lock according to the invention is designated quite generally with 1o. The lock instructs Lock housing 12 on. The left in Fig. 1 side wall of the lock housing 12 is of a latch bolt The latch bolt 14 is contrary to the action of springs not visible in FIG. 1 can be pushed into the interior of the lock housing 12. The end of the latch bolt located in the lock housing 12 14 is designed as a fork 16, the legs 18, 2o take up a guide pin 24 which is perpendicular to the housing bottom 22 between them.

6Q9811 / 0002

The latch bolt 14 carries inside the lock housing 12 a pin 26 normal to the main plane of the lock, which is called an edge follower pin in the following because it interacts with actuating edges. Both sides of the latch bolt axis are doubled in mirror image two handle nuts 28 and 3o stored.

Each handle follower 28, 3o has a cam 32 or 34, which on actuating lugs 36, 38 of two slide elements' 4o, 41 attack.

The slide elements 4o, 41 lie on top of one another according to FIG. 1 and can be moved relative to each other.

The slide elements are assigned to one another in such a way that their actuating lugs 36, 38 are opposite one another.

Each of the slide elements has an elongated hole 42 ·, 42 ¹¹ , 44 ·, 44 ″ in the region of its ends, which are aligned with one another and penetrated by guide pins 46, 48 perpendicular to the base 22 of the lock housing 12. In the region between the elongated holes 42 ·, 42 · ', 44', 44 ' ^f , each slide element has a widened section. In this widened section, the slide elements 4o, 41 are broken up by link cutouts 5o, 52, shown in dashed lines, which interact with edge follower pin 26. Both link cutouts 5o, 52 each have an idle slot 54, 56 that is essentially perpendicular to the latch bolt axis.

689811/0002

The latch actuation edges 62, 64 form at the transition into the associated idle slots 54 and 56, respectively, disengagement apex edges 66, 68, which in the unlocked state of the lock accommodate the edge follower pin 26 between them and define a passage slot for it. The guide edges 58, 6o of the slide elements 4o, 41 form together a lost motion slot 70, along which the edge follower pin 26 when the latch bolt 14 is actuated is movable. The actuating lugs 36, 38 of the slide elements cooperate with the arms 72, 74 of coil springs 76, 78. The coil springs 76, 78 enclose the lock base 22 perpendicular guide pins 80, 82. Further spring arms 84, 86 are on the upper and lower Housing wall 88, 90 and tension the slide elements 4o, 41 in their rest position.

So that the actuating nose 38 of the slide element closest to the lock base 4o comes into engagement with the crouch 34 of the handle follower 3o, it is slightly bent towards the viewer of FIG.

A release template 92 rests displaceably on the upper slide element 36 in FIG. 1. It is by means of Longitudinal slots 42, 44 guided on guide pins 46, 48 so as to be displaceable relative to slide elements 4o, 41.

On its longitudinal edge pointing to the keyholes, the release template 92 has actuating projections 94, 96, 98, which interact with the bits of tumbled keys inserted into the keyholes in such a way that the release template can be moved in the direction of arrows F and P with each key.

609811/0002

In its central section, the release template 92 has a substantially extending in the latch bolt axis horizontal lost motion slot 1oo, which is at least part of its length with the lost motion slot 70 of the slide elements covers. This makes it possible for the edge follower pin 26 - it also penetrates the release template 92 - can be moved freely along the latch bolt axis when the latch bolt 14 is actuated. At the end of the lost motion slot 1oo of the release template 92 on the left in FIG. 1, two border against the line of symmetry inclined and with respect to them mirror-inverted disengagement slots 1o2, 1o4, which with the Lost motion slot 1oo are connected.

The edge follower pin located in the lost motion slots 7o, 1oo When the latch bolt 14 is in the rest position, 26 rests under pretension against an approximately semicircular end stop 1o6 of the release template 92.

The release slots 1o2 and 1o4 of the release template 92 v / iron at their ends remote from the lost motion slot 1oo namely on the edge pointing to the keyholes vertical stop edges 1o8, which prevents that at disengaged, in one of the idle slots 54, 56 of the Slider elements 4o, 41 located edge follower pin by pushing the latch bolt 14 into the lock housing 12, the release template 92 can be pushed back into its neutral position (FIG. 1).

When moving the release template 92 in the direction of arrow P with the help of the key bit one in the in of the Fig. 1 lower keyhole introduced key ent-

603811/0002

the end stop 1o6 moves away from the edge follower pin 26; as a result, the edge follower pin 26 moves in the lost motion slot 70 of the slide elements 4o and 41 in FIG. 1 to the left, the latch bolt 14 being pushed a little out of the lock housing 12. This shift takes place due to a latch bolt spring, not shown, and primarily due to the related the latch bolt axis inclined release slot 1o4, the inclined side edges of which move back and forth of the edge follower pin 26 in the lost motion slot 70.

When the release template 92 is displaced by the beard of a keyhole introduced through the upper keyhole in FIG The lock-out key causes the release slot 1o2 to disengage the edge follower pin 26 via the Lost motion slot 70 in the area of the idle slots 54 and 56. In these disengaged positions, the edge follower pin is out of action of the actuating edges 5o and 52 of the slide elements 4o, 41, which, however, without simultaneous actuation of the latch bolt are movable.

On the opposite of the actuating projections 94, 96, 98 Longitudinal edges of the release template 92, this has a locking notch approximately in the middle between its ends 112, in which the complementarily shaped free end of the arm of a spiral spring 114 engages to to hold the release template in its neutral position (Fig. 1). The coil spring 114 encloses you Guide pins 116 which are perpendicular to the housing base and have a rectangular cross-section.

609811/0002

The mutual distances between the handle nuts 28 and 3o as well as the keyholes arranged between the handle followers are dimensioned in such a way that, regardless of whether the lock is used on the right or left, with a single cover plate on each lock side.

Such a cover plate then has only one opening for the implementation of a handle axis and a keyhole on. This means that the handle follower hole and keyhole on one side of the door that are not in use can go through the cover plate be covered. If the door is turned, then only the cover plates need to be turned over.

In the cover of the lock housing 12, not shown, there are recesses for the handle nuts and keyholes intended. A guide slot is also provided for the edge follower pin 26, holes into which the free ends of the guide pins 46 and 48 engage, as well as Holes for cover fastening screws, which are in vertical position on the housing base, with internal thread provided fastening bolts 118, 12o engage.

The two slide elements 4o, 41 and the release template 92 can be seen in plan view in FIGS. 2-4. The same reference numerals are used in FIGS. 2-4 as in FIG. 1; no further description is required therefore.

Regarding the release template 92, it should also be noted that the actuating projections 94, S6, 98 have flattened corners, which do not prevent the key bits from turning.

5 shows the lock housing 12 with the latch bolt 14 guided therein.

The forked end 16 of the latch bolt 14 is guided in the area between the keyholes from the protruding into the interior of the lock housing 12 edges of two indented areas 31, 33 of the housing base 22, in many cases there are keyholes and follower openings. The head of the latch bolt guide bolt 24 engages over the fork legs 18 and 2o.

The filler bar 14 is in the area between its ends abutment shoulders 37 and 39, on each of which an arm 41 and 43 of two leaf springs 45 and 47 surrounding the guide pins 46, 48 rest; these springs put the latch bolt 14 under tension. One further spring arm 49 and 51 each of the spring 45, 47 rests on the circumference of the housing cover fastening bolts 118, 12o.
