EP0972900B1 - Espagnolette lock - Google Patents

Abstract

A slider activated door lock has a spring loaded latch (5) which is pulled back by a slider (18) operated by the lock and by a retracting lever (36) which is operated by the door operating handle. The retracting lever has a pivot axis (35) behind that (10) of the door handle. The retracting lever is mounted in an extension to the top of the lock housing and has an extension arm (39) contacted by a cam (9) on the door handle mounting.

Description

The invention relates to a drive rod lock according to the preamble of claim 1.

Such a closure is known from the EP 0 834 633 A1 , wherein the latch tail is designed in two parts. The front part of the latch tail carries the case head, while the rear part is coupled via a pivot pin with the return lever. At the rear part then attacks the Nussarm the pusher. In this version, the pivot axis for the pull-back lever between the case head and nut extends, so that particularly small backset dimensions are not feasible.

From the DE 35 05 379 is an espagnolette with latch and bolt previously known. The bolt can be closed by pressing a lock cylinder back and forth. Along with this, an espagnolette slide is transversely displaced therefrom. The trap can be withdrawn both by a pusher and the lock cylinder by changing operation. The change lever engages the latch and is mounted on a rearwardly and below the nut arranged bearing pin.

The EP 0 091517 describes a similar closure. Again, the case can be dragged back both by handle operation as well as by alternating operation. Again, a change lever is provided, the pivot bearing is located behind and below the nut.

The invention has the object of providing a generic espagnolette with a simple structure in such a way that particularly small mandrel dimensions can be achieved.

The object is achieved by the invention specified in the claims.

According to such an embodiment, espagnolette lock of the type in question is of simple construction realized. The latch tail can now be designed in one piece as a result of the rear lever mounted on the return lever. Along with this, a reduction of the backset to 35 mm and smaller is possible. Accordingly, the espagnolette lock can also be best associated with tubular frame doors. Nevertheless, there are no disadvantages in terms of panic function, so the vorgeschlossenen bolt, and the upstream espagnolette slide the default case retreat from the inside of the door by means of the pusher. The per se proven design of a generic espagnolette closure can be largely maintained, since the housing cover and housing bottom form a recess lying above the nut axis, in which a retainer lever bearing housing extension is arranged. The bulge is such that the extension is aligned with the Schloßgehäuserückkante, so that there are no disadvantages in terms of installation depth. In detail, such a configuration that a drive arm of the retraction lever can be acted upon by a Nußarm. Thus, the Nußarm acts directly on the return lever, which allows a favorable force application to the espagnolette gate valve by means of the retracting lever. It is further provided that the drive arm pivots in the closing movement of the Nußarmes when Schließzylinderbetätigten locking latch. In a panic situation, accordingly, the immediate entrainment of the retraction lever takes place, which in turn acts on the espagnolette slide in conjunction with the handle shift. At a low installation depth then contributes that the drive arm partially overlaps the latch tail in vorgeschlossener latch position. Then, the embodiment of the invention allows the realization of a drive rod closure with split nut. The corresponding two-parted nut points an inner and outer half of the nut, wherein the outer half of the nut acts only on the latch tail and actuates both trap and retraction lever in the inner half of the nut. The required unilateral clearance between the two nut halves is easier. Way created by the inner half of the nut associated Nußarm entrained the outer half of the nut associated Nußarm during its pivoting. Furthermore, the invention provides that the angular retraction lever is curved sickle-shaped and rests with its sickle cavity in its caused by the pusher groove open position of the espagnolette corresponding position on a sleeve of a fitting screw passage opening. As a result, the return lever undergoes a support. A further advantageous feature is the fact that the output arm in its position corresponding to the open position of the espagnolette closure partially overlaps the latch tail when the latch is retracted. So there is a nesting instead, which allows the construction of a crowded castle. Finally, it should be emphasized that the output arm engages in a recess of a vertical portion of the drive rod terminal slide. This intervention is not given up in the locked or withdrawn latch, so that always the proper closing function is guaranteed.

The illustrated espagnolette has a connected with a faceplate 1 lock housing 2. At the back leads to the forend 1 an upper and lower escaping from the lock housing 2 drive rod 3 and 4. The latter are provided with non-illustrated latch members, in a known manner with frame-side counter-closing parts interact.

In the upper part of the lock housing 2, a case 5 is guided. Its case head 6 is connected to a latch tail 7. End this forms a driving projection 8 from the attack of a Nußarmes 9 a pusher 10. According to the in the FIGS. 1 to 5 illustrated embodiment, the pusher 10 is designed in one piece. The pusher 10 is provided with a further Nußarm 11, which via a parallel to the forend 1 extending spring slide 12 counterclockwise is charged. The spring slide 12 is under the action of a compression spring 13. The nut 10 including the spring slide 12 and compression spring 13 are received by a mountable in the espagnolette nut bearing housing 14. The latter also includes an unillustrated stop, which serves as a stop limit for the nut 10 in its normal position.

For forward displacement of the case 5 is designed as a torsion spring latch spring 15 which is supported by a lock housing side standing pin 16. The forward movement of the trap 5 is limited by stops. Your case head 5 passes through a shape-matched opening 17 of the Stulpes. 1

Below the case 5, a bolt 18 is guided in the lock housing 2, the bolt head 18 'passes through a cross-section adapted opening 19 of the Stulpes 1.

The lock bottom 20 and arranged parallel to her lock cover 21 carry between them a support plate T. These stored in its lower part in a lock cover 21 facing bore 22 a ring gear 23. A lock cylinder insertion opening 24 crosses this hole. The axis of rotation of the cylinder core not shown is eccentric to the axis of rotation of the ring gear 23, below it.

The sprocket 23 has a radially directed push-through gap for a dash-dotted illustrated closure member 26 of a profile lock cylinder, not shown. This is designed as a so-called freewheel with freely rotatable when removed key Closing member 26. With key insertion, however, the closing member is coupled to the cylinder core.

With the external teeth of the ring gear 23 mesh two output gears 27, 28 of a reduction gear G. Its end 29 meshes with a guided parallel to the face plate 1 rack 30 of a drive rod connection slide 31, which is guided in the upper region of the lock housing 2 and the upper drive rod 3 carries.

In parallel opposite to the rack 30, a further rack 32 is guided, which extends parallel to the aforementioned rack 30. The rack 32 is part of a further espagnolette slide 33, which is guided in the lower region of the lock housing 2 and the lower drive rod 4 carries. In this way, the driving rod connecting slide 31, 33 are driven in opposite directions by the end wheel 29 of the reduction gear G and thus the drive rods 3, 4th

The espagnolette 31 controls the interposition of a pivot lever 34, the bolt exclusion in such a way that initially the espagnolette connector 31 precedes the bolt exclusion and then the entrainment of the bolt 18 takes place. As a result, the first drive rod-side locking members can first attack and cause the door to tighten, so that then the latch 21 can enter into the associated Schließblechausnehmung without hindrance. This is from the EP 0 834 633 A1 known, so that it is not discussed further. This also applies to the changeover operation, with the lower drive rod connection slide not illustrated Interchangeable lever acted which in turn pulls the latch 5 lock inward.

Above and behind the nut 10 is a pivot axis 35 for an angular retraction lever 36 for retraction of the upper espagnolette 31 and thus on the end wheel 29 of the lower espagnolette slide, which causes the retraction movement of the locked latch 18.

The pivot axis 35 is formed by a housing extension 37, for which the housing bottom 20 and the housing cover form an aligned, above the nut axis lying bulge 38, see. especially Fig. 5 , The downwardly and in the direction of the nut 10 facing drive arm 39 of the retraction lever is positioned so that it can be acted upon by the Nußarm 9. When bar lock, cf. Fig. 2 , the drive arm 39 is pivoted into the path of movement of the Nußarmes 9, see. Fig. 2 , In this pre-closed locking position, the drive arm 39 partially overlaps the bolt tail 7 or its driving projection 8. The angle-shaped retraction lever 36 otherwise has a sickle-shaped curvature. The sickle cavity 42 formed by the output arm 41 is located in the open position of the espagnolette closure caused by the presser foot 10 on a sleeve 43 of a fitting screw passage opening 44, cf. Fig. 4 , The sleeve 43 is also part of the housing extension 37. Also leaves Fig. 4 recognize that the output arm 41 partially overlaps the latch tail 7 in its position corresponding to the open position of the espagnolette when the latch 5 is retracted. To attack the Abtriebsarmes 41 forms an upper vertical portion of the espagnolette gate valve 31 a recess 40, in which the free end of Abtriebarmes 41 dips.

The so-designed espagnolette lock allows to realize a backset which is equal to or smaller than 35 mm.

The following mode of action occurs:

If the door equipped with the drive rod lock constructed in accordance with the invention is closed, then only the latch 5 is in the engaged position with respect to a counter-closing part on the door frame side. From the outside of the door, the latch 5 can be withdrawn by locking cylinder actuation via the closing element 26. At the corresponding closing rotation, the closing member 26 takes the sprocket 23 in the clockwise direction. About the end 29 of the reduction gear G learns the espagnolette slide 33 an upward displacement, where he pivots the unillustrated change lever and pulls over this the case 5 in a known manner in Schloßeinwärtsrichtung. A lock housing side arranged torsion spring 45 is in this case stretched over the upper end of the espagnolette slide 33, which torsion spring 45 after key operation the espagnolette connector slide 33 returns to its original position.

The retraction of the case 5 from the inside of the door is possible by means of a dash-dotted illustrated Türdrükkers 46. In its downward displacement is pulled over the Nußarm 9, the case 5 in the inward direction, against the force of the latch spring 15th

The closing of the bolt 18 when the door is closed requires a closing rotation of the closing member 26 in the counterclockwise direction. About the ring gear 23 and the reduction gear G, the espagnolette gates 31, 33 are moved in opposite directions, namely the upper espagnolette 31 up and the other espagnolette 33 down. After a certain displacement of the espagnolette slide 31 is pivoted about the rack 30, the pivot lever 34, resulting in a Ausschließbewegung of the bolt 18, in the position according to Fig. 2 , As a result of the recess 40 of the upper espagnolette slide 31, the retraction lever 36 is pivoted so that its drive arm 39 then overlaps the driving projection 8 of the latch tail 7 and immediately lies close to the Nußarm 9.

Starting from the pre-closed position of the bolt 18, it is possible from the inside of the door to open the espagnolette lock without key operation - to achieve a panic function. For this purpose, the door handle 46 is to depress and thus to pivot the pusher 10. Their Nußarm 9 acts on the driving projection 8 of the latch tail 7 connected to the fact that the case 5 is pulled in Schloßeinwärtsrichtung. In addition, the nut arm 9 also urges the drive arm 39 of the retraction lever 36, the output arm 41 of which engages in the recess 40 moves the drive rod connection slide 31 in the downward direction. About the end 29 of the reduction gear G, the other gears of the reduction gear G are rotated and thus also the output gears 27, 28 which rotate the ring gear 23. This is possible because the corresponding profile lock cylinder is designed as a freewheel cylinder, which with the key removed the rotatability of the closure member 26 relative to the locked cylinder core permits. Both on the end wheel 29 in opposite directions moving rod connection slide 31, 33 go while passing through an intermediate position in Fig. 3 in the position according to Fig. 4 , in which all latch members including trap 5 take the Rückschließstellung. The door is thus openable. If then the door handle 46 is released, the case 5 returns to its previous position. Further, the pusher 10 is rotated back to its initial position by the spring slider 12.

In the in the FIGS. 6 to 9 illustrated second embodiment, like components carry like reference numerals. The pusher nut 47 is now divided into two parts in such a way that the dividing plane runs parallel to the lock cover and lock bottom. In detail, the pusher nut 47 is composed of an inner half nut 48 and an outer half half 49 of the nut. Both nut halves 48, 49 are each equipped with a Nußarm 50 for attacking the spring slider 12. The outer Nußhälfte 49 then has a further Nußarm 51, which extends outside the trajectory of the drive arm 39 in another plane and only on the Fallen tail 7 and whose driving projection 8 acts. The inner half nut 48, however, forms a Nußarm 52, which actuates both the latch 5 and the retraction lever 36. For this purpose, the nut arm 52 assigned to the inner half of the nut 48 tows the nut arm 51 associated with the outer half of the nut 49 during its pivoting, thereby realizing a unilateral clearance.

The operation of this second embodiment largely corresponds to that of the first embodiment. The outer nut half 49 now also carries an actuating handle. However, only the trap 5 can be withdrawn with it, cf. Fig. 7 ,

Upon displacement of the inner Nußhälfte 48 by means of the inner handle of the Nußarm 52 acts on the drive arm 39 of the retraction lever 36 and transferred via the output arm 41, the drive rod terminal slide 31 in its open position. At the same time the bolt is closed back. Further, the Nußarm 52 acts on the Nußarm 51 of the outer Nußhälfte 49, which Nußarm 51, the latch 5 draws lock inward, see. Fig. 8 ,

According to this second embodiment, the inner half of the nut 48 is provided in the region of the pusher mandrel opening with a projecting collar 53, which fits in a bearing cavity 54 of the outer half of the nut 49, cf. Fig. 9 , In this way, both nut halves 48, 49 receive improved guidance.

The in the FIGS. 10 to 13 illustrated third embodiment is similar to the above. Again, it is true that the same components carry the same reference numerals. The pusher nut 47 'is also divided into two, consisting of the outer half of the nut 48' and the inner half of the nut 49 '. The latter is equipped with an inwardly projecting collar 53 'which dips into a bearing cavity 54' of the outer half nut 48 '. The mode of action corresponds to the preceding one. When moving the outside door handle, the outer half of the nut 48 'in the position according to Fig. 11 pivoted, with one of the Nußarm 52 'pulls the lock 5 lock inwards and the other Nußarm 50' displaces the spring slide 12. The inner nut half 49 'stops.

If the door inner handle is in accordance with Fig. 12 actuated, it pivots the inside of the door nut half 49 ', which carries on its Nußarm 51', the outer Nußhälfte 89 'according to the one-sided clearance. The outer half of the nut 48 'pulls back on its Nußarm 52' the case 5, wherein the Nußarm 52 'also acts on the retraction lever 36.
