Description

genus

The The invention relates to an espagnolette lock.

State of the art

Rotary bar locks are already known in various constructions. One of the applicant's protected solution is from the DE 10 2004 006 608 B3 refer to. Such espagnolette locks are usually used for furniture, but also for locking bathroom doors, in motor homes, caravans, on yachts or the like. The advantage of espagnolette locks is, inter alia, that they allow a three-point locking, just above the two hooks arranged at a considerable distance from each other and by a central latch or a latch. In some cases, however, it depends only on certain conditions to lock the relevant door or the like at three points. Then the locking hooks are disturbing. For example, in changing rooms existing dressing rooms are equipped with such espagnolette locks, but a three-point locking in daily use is unnecessary. In contrast, a three-point locking is desirable if such doors are not needed for a long time, for example, seasonal. During a longer period of weeks or months, it could otherwise lead to warping of the doors or the like, so that in particular the rotary hooks would only bring back into a final state after considerable adjustment work.

task

Of the Invention is based on the object, an espagnolette lock create, if necessary, a three-point interlock, as even by just pulling the door or the like allows one-point locking.

solution

These The object is achieved by the reproduced in protection claim 1 features solved.

Some advantages

The Inventive espagnolette lock allows it, by a rotary movement of the handle, for example an olive, a pusher mandrel or the like, at an acute angle to bring the rotary hooks in unlocked position, but the trap in the state emerging from the lock case, ie in the locked position, to leave. In this case, the door in question needs merely to be contracted or slammed to them first to keep in their closed position. Will the handle to a further twisted angle, the trap is also in the lock case moved in, so that then the door without a rotary motion move the locking hook to the open position leaves. Especially if a frequent use of required for opening furniture or cabins is, such an espagnolette lock is good to handle, because it Often it is sufficient to operate only the trap to close a door or the like and in the If necessary, by returning the trap again to open. In contrast, in the inventive Lock also desired a three-point lock needs the handle only in the opposite direction to a point Turning angle to be turned to next to the if necessary automatically by resilient restoring force coming out of the lock case Fallenkopf also the locking hook in locking position to move.

Further inventive embodiments

Further inventive embodiments are in the claims 2 to 13 described.

Some advantages

The Embodiment according to protection claim 2 allows it, with a simple, robust component, namely a Double drive, eccentric and driver, the latch and the locking hook to be actuated successively by a rotary movement of the handle. Such a double eccentric also allows decoupling the movement of the latch on the one hand and the case head on the other hand, which - as described - in If necessary, bring the lock in three-point locking, or even the locking hook in the open position let move, so that only the trap serves as a locking part.

The Embodiment according to protection claim 3 allows a compact, space-saving design because the double-drive nut, Fallen tail and other Schlosseingerichtetilen each other is arranged.

In the drawing, the reference numeral 1 a lock case referred to on one side by a castle ceiling 2 by means of four screws 3 in the corner areas is releasably closed to the outside. The castle ceiling 2 closes flush with the edges of the lock case 1 outwards.

at 4 and 5 are with the lock case 1 materially arranged in one piece approaches with slot openings 6 respectively. 7 provided by the fastening screws, not shown, for the purpose of fastening the espagnolette lock on a wall, for example, a cabinet door, can be passed.

On diametrically opposite sides of the approximately rectangular in plan view lock case 1 are openings with one piece on the walls of the lock box 1 molded bearing blocks 8th respectively. 9 provided, in each of which a rotatable by a limited angular extent coupling body 10 respectively. 11 are arranged. Each coupling body 10 respectively. 11 is with a part-ring collar neck 12 respectively. 13 provided with the relevant coupling body 10 respectively. 11 in a slot-shaped bearing recess of the respective bearing block 8th respectively. 9 is arranged rotatably. Each coupling body 10 and 11 has on its outwardly facing end face with a provided here, the side wall of the lock housing 1 penetrating opening coaxially arranged bag-shaped recess having a corresponding profiling, in each of which a rotary rod 14 respectively. 15 with a shape of the respective coupling body 10 and 11 adapted profiling positively engages, so that a geared connection between the respective coupling body 10 respectively. 11 and the associated rotary bar 14 respectively. 15 is made by plug connection. Every turning bar 14 . 15 usually carries on her the lock housing 1 remote end portion a closing hook 16 . 17 , The turnstiles 14 and 15 Incidentally, they are in rotary bar bearings 18 respectively. 19 , which are fastened to a furniture part, for example a cabinet wall, by screws, rotatably mounted.

The lock box 1 has an opening on one end face 20 , through which a trap with its provided with a run-on slope head 21 can emerge. The case head 21 is materially integral with a trap tail 22 in the case 1 against the restoring force of two spring elements designed as compression springs 23 and 24 arranged longitudinally displaceable. The spring elements 23 and 24 grab with their one end in blind holes of the tail-tail 22 a (not shown) and supported with its opposite end to the inside of the lock box 1 under pretension.

The trap tail 22 is materially integral with the case head 21 trained and owns in the lock case 1 one transverse to the longitudinal axis 25 of the case head 21 and the tail-tail 22 considerable enlargement 26 that are symmetrical to the longitudinal axis 25 is arranged. This enlargement 26 the width dimension of the trap tail 22 serves as a stop of the trap when the case head exits 21 from the lock case 1 , where the magnification 26 against the inside of the lock case 1 strikes. Also in this position are the spring elements 23 and 24 still under tension.

The trap tail 22 has a flattening 27 that are symmetrical to the longitudinal axis 25 is arranged and the longitudinal axis on diametrically opposite sides of a limited by a circular arc shoulder 28 and on the opposite side shoulders 29 and 30 forms. As you can see, the flattening runs 27 parallel to the bottom 31 of the tail-tail 22 , In addition, has the tail-tail 22 on the case head 21 facing away at the bottom 31 two spaced not shown the wall 32 on the bottom 31 arranged longitudinal recesses 33 , in each case a material with the lock case 1 trained rib as a guide engages and the fall tail 22 thus leads axially aligned.

The trap tail 22 moreover, it has an opening which is largely rectangular in the center and approximately right-shaped, and which is delimited by circular arcs at the sides which are diametrically opposite in the longitudinal axis direction 34 on, symmetrical to the longitudinal axis 25 is arranged.

On the trap tail 22 is an approximately rectangular in plan view, frame-shaped rotary rod drive element 35 arranged in the longitudinal axis on diametrically opposite sides down into the lock case 1 right-angled protruding, equal-sized webs 36 and 37 at their bottom of the lock box 1 located on diametrically opposite sides slot-shaped drive openings 38 respectively. 39 having, in each of these drive openings 38 and 39 each engages a crank pin not shown in the drawing gear, and each coupling body 10 respectively. 11 is integrally connected with such a crank pin. In the axial displacement of the rotary rod drive element 35 Thus, a rotational movement of the coupling body takes place 10 and 11 by actuating these crankpins by a certain Drehwinkelmaß, which then causes the turning rods 14 and 15 according to their longitudinal axes synchronously and simultaneously with the locking hooks 16 and 17 in their camps 18 and 19 rotated and thus brought either in the closed position (locking position) or in the open position (unlocking position).

The rotating rod drive element 35 also has a centric opening 41 that with the opening 34 of the tail-tail 22 corresponds and thus the opening 41 over the opening 34 of the tail-tail 22 in the direction of the longitudinal axis 25 is arranged slidably and slidably.

With the reference number 42 is a nut referred to, which in the embodiment shown in the drawing a square coupling opening 43 for coupling with a handle, for example an olive, a pusher mandrel or the like. If necessary, the lock can also be provided with a handle on both sides of a piece of furniture, for example a door, in order to actuate the revolving rod lock in the manner to be described.

The Nut 42 has in the axial direction one behind the other material in one piece or functionally integrally arranged an eccentric 44 and a driver 45 , where the eccentric 44 in the illustrated embodiment by an angle of about 85 degrees and the driver behind it in the axial direction 45 extends over a rotation angle of about 5 degrees. The eccentric 44 and the driver 45 are offset by an angular extent of for example 85 degrees against each other in the direction of rotation, so that during a rotational movement of the nut 42 via a handle, not shown, first the eccentric 44 over the rotating rod drive element 35 the espagnolettes 14 and 15 and with it the closing hooks 16 and 17 rotates and in another rotation over an acute angle of, for example, 40 degrees, the driver 45 becomes effective in the recess of the tail-tail 22 engages and then the case head 21 in the lock case 1 moved in and unlocked. Are the locking hooks 16 and 17 in locking position and is the case head 21 from the lock case 1 stepped out, so are head of the trap 21 and closing hook 16 and 17 over the nut 42 blocked against an opening shift.

If, on the other hand, the handle, for example an olive, is rotated by about 90 degrees in the direction of opening, the catch hooks pivot 16 and 17 in open position, so are unlocked, however, while the case head 21 still from the lock box 1 in locking position. For example, this location can be comfortable for bathing cells that do not necessarily rely on three-point locking, such as when a person just wants to move. Then, the door can not be easily pulled from the outside, unless the handle is rotated by another acute angle of, for example, 40 degrees. Then it is also about the driver 45 the case head 21 in the lock case 1 moved in, so the relevant door or the like completely unlocked. If, on the other hand, the furniture or a bathroom cubicle is to be closed for a longer period of time, which may be the case, for example, with bathing cubicles in the winter season, both the closing hooks will be used 16 and 17 , as well as the case head 21 placed in the locked position so that, for example, the door or the like can not distort.

With the reference number 46 is a ball referred to in a tubular receptacle 47 of the lock case 1 against the resilient restoring force of a compression spring element 48 is arranged. The nut 42 facing mouth opening of the recording 47 is narrowed, so the ball 46 can not fall out inside. The ball 46 engages in a longitudinal groove 49 the nut 42 and locks them in the open position of the locking hook 16 . 17 , so that the handle remains in a defined position. When pivoting the handle becomes the ball 46 against the restoring force of the compression spring element 48 pushed away and then gives the nut 42 free for a rotational movement, so that the eccentric 44 and the driver 45 can be used accordingly.

With the reference number 50 is the longitudinal axis of the coupling opening 43 and thus the axis of rotation of the nut 42 designated while 51 one with the castle ceiling 2 materially or functionally one-piece stop shown, the nose-shaped in the rotational movement of the nut 42 , and a groove 52 at the front of the nut 42 arranged and designed to be open to the outside. Through the grooves the stops are formed. These stops are offset by 90 + 40 = 130 degrees in the illustrated embodiment offset from each other. If these attacks did not exist, you could be the nut 42 turn infinitely in any direction.

The "R" indicates in the drawing a right-closing lock. In a left-closing lock, the parts must be arranged in mirror image. In 1 the latch is locked and the espagnolettes are also locked. In 4 the latch is locked and the espagnolettes are opened. One recognizes this from the fact that the "R" in 1 is located on top of the midline and in 4 turned 90 degrees to the right. In 6 are both the trap 21 as well as the turnstiles 14 and 15 locked, as the "R" has been further rotated by another acute angle of 40 degrees 4 ,

In the embodiment according to 11 For example, the angles α and β are formed at an acute angle and are each 45 degrees, for example, thus complementing one another at a right angle, which is denoted by γ.

The driver 45 In the illustrated embodiment, the angle δ of 5 degrees, while the angles α and β are each 45 degrees and the angle ε in the illustrated embodiment is 85 degrees. The angle φ is 135 degrees.

The described in the claims and in the description as well as apparent from the drawing features can both individually and in any combination for realization be essential to the innovation.
