Door-locking mechanism having a receptacle set into the door frame for the locking bolt of a device set into the door for controlling the locking bolt into the open position by means of a manually controllable actuating element

Abstract

The invention relates to a door closer mechanism having a receptacle, countersunk in the door frame, for the deadbolt of a device, countersunk in the door, for controlling the deadbolt from the closing position to the opening position by means of a manually controllable actuation member. So that, without an additional key-actuated lock, the closing position can be locked in the closing position and fixed without making the ease of adjustment into the opening position more difficult, the invention provides that the actuation member of the device countersunk in the door is embodied as a handle recess, which in the closing position controls a slide via a rotatably supported angled control piece, and the slide, via a rotatably supported lever, secures the deadbolt in the receptacle in the door frame, and upon actuation of the recessed handle in the door, via the angled control piece and the slide, the deadbolt can be adjusted into the opening position of the door, and the door is enabled to open.

Claims

1. A door closer mechanism having a receptacle, countersunk in the door frame, for the deadbolt (14) of a device, countersunk in the door, for controlling the deadbolt (14) from the closing position to the opening position by means of a manually controllable actuation member (12), characterized in that the actuation member (12) of the device countersunk in the door is embodied as a recessed handle (12), which in the closing position, via a rotatably supported angled control piece (19), controls at least one of a plurality of slides (17), and the at least one of a plurality of slides (17), via a rotatably supported lever (15), secures the deadbolt (14) in the receptacle in the door frame; that upon actuation of the recessed handle (12) in the door (10), via the angled control piece (19) and the at least one of a plurality of slides (17), the deadbolt (14) can be adjusted into the opening position of the door (10), and the door (10) is enabled to open; and the device with the recessed handle (12) can be built into the door in such a way that it assumes four different positions, each rotated by 90° from one another, and the recessed handle (12) can be swung toward the bottom, to the left, toward the top and to the right, out of the frame (11) that is joined to the door.

2. The door closer mechanism of claim 1, characterized in that the recessed handle (12) is let flush into a frame (11) of the device in the door and can be swung out of the frame (11) and thereby adjusts the angled control piece (19), the at least one of a plurality of slides (17), and the lever (15) such that the deadbolt (14) moves out of the receptacle in the door frame.

3. The door closer mechanism of claim 1, characterized in that the recessed handle (12), except for an opening in the handle, extends beyond the frame (11) and thus makes it easier to grasp the recessed handle (12) for actuating the door closer mechanism.

7. The door closer mechanism of claim 1, characterized in that the angled control piece (19) in the frame (11) is rotatably supported around the recessed handle (12).

Description

(1) The invention will be described in further detail in an exemplary embodiment in conjunction with the accompanying drawings. They show:

(2) FIG. 1, a frame countersunk in the door, having a recessed handle open toward the top; the deadbolt 14 protrudes from the front side of the door 10;

(3) FIG. 2, the device of the door closer mechanism, which is countersunk in the door 10; FIG. 2 shows the frame 11 with the recessed handle 12 from behind;

(4) FIG. 3, the components which cooperate with one another in the door closer mechanism;

(5) FIGS. 4 and 5, the components of the device of FIG. 2 with the recessed handle 12 open toward the top;

(6) FIGS. 6 and 7, the components of the device with the recessed handle 12 open at the bottom;

(7) FIGS. 8 and 9, the components of the device with the recessed handle 12 open to the left;

(8) FIGS. 10 and 11, the components of the device with the recessed handle 12 open to the right; and

(9) FIGS. 12 and 13, the components of the device of FIG. 2 with the recessed handle 12 open toward the top.

(10) FIG. 1 shows a detail of a door 10, in which there is a countersunk a frame 11 that has a recessed handle 12 open toward the top. In the closing position, the deadbolt 14 protrudes from the vertical front side of the door 10. This deadbolt 14 is guided in a plate 13, which is connected to the front side of the door 10. The plate 13 is let flush into the front side of the door 10.

(11) FIG. 2 shows two components of the device, which are countersunk in the door 10 from the back side. In the component that is provided with the plate 13, the components are covered by a plate 21. On the back side of this component, a slide 17 protrudes outward, and an angled control piece 19 is associated with it. The back side of the frame 11 is provided with the angled control piece 19 and the recessed handle 12 in such a way that upon actuation of the recessed handle 12, the angled control piece 19 is rotated and in the process adjusts the slide 17 parallel to the deadbolt 14.

(12) As can be seen from FIG. 3, upon an adjustment of the slide 17, the lever 15 is rotated about the locator pin 16. In the process, the deadbolt 14 is drawn inward on the locator pin 22 and in the process moved entirely out of the receptacle in the door frame (not shown). The door closer mechanism assumes its opening position, and the door 10 can be opened. The slide 17 is provided, in the vicinity of the locator pins 23 and 24, with guide receptacles that permit the slide 17 to be adjusted parallel to the deadbolt 14. The plate 13 is connected to a plate 25 vertical to it, which has the locator pins 16, 23 and 24. The lever 15 is coupled with the slide 17 and the deadbolt 14, so that a rotation of the lever 15 causes the deadbolt 14 to be retracted.

(13) FIGS. 4 and 5 show the two component groups in the door 10 in separate drawings. The drawings show that an angled control piece 19, which is rotatably located in the frame 11 of the recessed handle 12, is associated with the slide 17. The angled control piece 19 executes its rotary motion then when the recessed handle 12 is swung outward from the frame 11. This rotary motion is transmitted to the slide 17, which as a result causes the retraction motion and adjustment of the deadbolt 14 into the opening position.

(14) As FIGS. 6 and 7 show, the recessed handle 12 can also be built into the frame 11 in such a way that the recessed handle is open toward the bottom. The angled control piece 19 is then associated with a second slide 17, which is longitudinally adjustable on the plate 25 and rotates a lever 15, which causes the deadbolt 14 to be retracted and puts the door closer mechanism into the opening position.

(15) In FIGS. 8 and 9, the recessed handle 12 is built into the frame 11 in such a way that the recessed handle 12 is open toward the left. The angled control piece 19 rotatably supported in the frame 11 is, with an extension 26 on the side facing toward the slide 17, embodied as an adjustable part 19 and in the process initiates the retraction of the deadbolt 14 and thus puts the door closer mechanism into the opening position.

(16) Finally, FIGS. 10 and 11 show the recessed handle 12 in a position in which it is open toward the right in the frame 11. Here, the angled control piece 19 is associated directly with the slide 17.

(17) FIGS. 12 and 13 show the components in the door 10 in separate drawings and are counterparts of FIG. 2.

(18) With FIGS. 4 through 13, it is shown that the incorporation of the recessed handle 12 into the frame 11 can be accomplished in four different positions. Thus the actuation of the recessed handle 12 is adapted to the most favorable conditions, without losing the advantages of the invention.
