Description

The invention relates to a folding handle closure for doors or flaps of cabinets or other containers.

For locking doors or flaps closures are known as so-called, for example in the EP 0 261 266 B1 described swing lever locks are formed. Here, in a cut-out in the door or flap a base plate is fixed, which is elongated and has a recess for receiving a folded in the rest position handle. The handle is pivoted out of the base plate in a direction perpendicular to the door or flap level and is rotatably mounted at its one end by means of an actuating axis in the base plate which engages in a rod lock or carries a tongue as a locking device for the door or flap, so that in the swung-out position of the handle by the rotation of the closure can be locked or unlocked. The hand lever has at its the actuator shaft opposite the free end of a cylinder lock, by means of which the hand lever pivoted in his in the base plate Position in this is lockable. Thus, the swivel lever lock is lockable.

With the known closure has the disadvantage that its operation is cumbersome. First, after unlocking the cylinder lock the hand lever must be folded out of the base plate and then rotated for the Endriegelung of the closure. As far as the cylinder lock is attached to the end of the hand lever, this cylinder lock obstructs the handling of the hand lever and also makes it difficult to pivot the hand lever into the base plate because the cylinder lock must be brought into alignment with the associated receiving opening of the base plate.

The invention is therefore an object of the invention to provide a lockable closure for doors or flaps of cabinets or other containers available that is simple and easy to operate.

The solution to this problem arises, including advantageous refinements and developments of the invention from the content of the claims, which are adjusted to this description.

The invention provides in its basic idea a folding handle closure with an insertable into a cutout formed in the door or flap and having a trough-like depression housing, wherein in the recess with recess a recessed handle a folding handle out of the housing folded out and the folding handle for actuation a bolt pivotally mounted on the part of the housing projecting on the inside of the door or flap, and wherein in the housing in addition to the folding handle a cam lock is arranged with an actuating shaft and a rotatable tongue carried therefrom such that the tongue in the closed position the cam lock locks the pivotal movement of the bolt. With the invention is the advantage connected, that for the operation of the closure, a folding out of the folding handle from the housing is sufficient. This results in only a single direction of actuation with a very short-lasting actuating path. Due to the separate arrangement of the cylinder lock in the housing, the cylinder lock does not interfere with the operation, however, is due to the blocking of the actuated by the folding handle latch in the. Closed position of the proposed cam lock closes the pivotal movement of the bolt, so that the folding handle closure is lockable as a whole.

According to one embodiment of the invention, it is provided that rotatably mounted on the housing one of the folding handle when it is folded out of the housing rocker, which lies with an approach against the bolt and this acted upon and that the tongue of the cam lock in its closed position the rotational path the rocker locks, which may further be provided that the rocker is biased by a spring in their the locking position of the bolt adjusting rest position. As a result, it is first of all ensured that the bolt is in each case in its locking position.

For functional connection of folding handle and bolt is provided that the folding handle acts on a longitudinally displaceably arranged in the housing actuating pin on the rocker. It can be provided that the axis of rotation of the hinged out of the housing folding handle in the housing is arranged eccentrically to the displacement axis of the actuating pin and on the folding handle an eccentricity bridging lever arm is provided. Due to the extent given coupling of rocker and folding handle, it is sufficient that only the rocker is biased by a spring in their the locking position of the bolt adjusting rest position, because on the actuating pin at the same time the spring force acts on the folding handle and this also in his at Provided locking position of the bolt and thereby conditional, holds in the housing folded position.

According to a preferred embodiment of the invention it is provided that the bolt relative to the rocker is mounted relatively movable and biased by a spring in its locking position. This results in two major advantages. On the one hand so that a snap function of the bolt when closing the door or flap is given, because even with blocked by the deflector lock rocker the door or flap can be closed, the bolt automatically pivoted against the predetermined by the deflector shutter rocker against spring force in the open position and thus allowing the door or flap to close while subsequently being pushed back by the spring into its position locking the door or flap. Furthermore, it is possible, despite the completed folding handle closure from the inside of the door or flap forth to open this by the bolt is pivoted against the force of spring acting on it by hand in its open position.

A simple design is then given, as far as according to an embodiment of the invention, latch and rocker are mounted on a single, arranged on the projecting on the inside of the door or flap portion of the housing bearing axis and rotatable about the bearing axis. In this case, for example, the spring acting on the rocker can be designed as a rotational spring acting on the axle and acting on the rocker and supporting itself against the housing, while the spring biasing the bolt is designed as a linearly acting compression spring which bears against the housing ,

Since it depends in particular on the tightness of the closure in the formation of such a folding handle closure, so that the passage of the functional parts of the folding handle closure is sealed by the door leaf, according to an embodiment of the invention, that the actuating pin by a in an this trained groove inserted seal against the housing sealed is. A further sealing of the folding handle in the housing is realized in that the provided for storage of the folding handle in the housing, mounted in apertures of the housing bearing pins are sealed over inserted seals against the housing. Likewise, according to the invention, the passage of the cam lock in the housing is sealed by means of a seal, and it is provided that the housing itself is sealed at its contact surface on the door leaf by means of an inserted seal.

the object of FIG. 3 from a different angle.

In FIG. 1 First, the built-in a door leaf 10 folding handle closure is shown; that door leaf 10 has a fold 11, with which the door leaf 10 comes to lie in its closed position in a frame angle 13 of a frame 11, wherein one of FIG. 2 apparent closure the door leaf 10 relative to the frame 12 determines.

In a recess formed in the door leaf 10 a housing 14 is inserted and fixed therein, which has a trough-like recess 15 in which a folding handle 16 is arranged to form a recessed grip 17. The folding handle 16 is sunk in the recess 15 so that it does not stand beyond, but in a later to be described Way out of the housing 14 is folded out. To seal the housing relative to the door leaf, the housing is sealed at its recess surrounding the recess and abutting the door leaf by means of an inserted seal against the door leaf 10.

In the recess 15, a dome for receiving a Vorreiberverschlusses 18 is further formed on the housing side, which consists of an inserted therein and actuated by a key 20 cylinder lock 19. As it turned out FIG. 2 results, sits on the shaft of the cam lock 18, a tongue 21 which is fixed to the shaft by means of a screw 22 so that upon rotation of the key 20, the tongue 21 rotates together with the key. There is also provided a seal for the passage of the cam lock 18 through the housing 14.

As it turned out FIG. 2 Next, a rocker 23 is pivotally mounted on the rear side over the door leaf 10 inwardly projecting housing 14, which also includes a pivotally mounted on the housing 14 bolt 24 which is biased by a supported on the housing 14 compression spring 25 in its closed position is, in which the latch 24 engages behind a latch holder 28, which in turn is secured by means of a mounting bracket 29 on the frame 12.

As is clear from the Figures 3 and 4 can be better seen, the rocker 23 and the latch 24 are mounted together on an axle 26 which is mounted in formed on the housing 14 bearing blocks 31. In this case, the acted upon by the compression spring 25 latch 24 is rotatably mounted in the area between the bearing blocks 31 of the axis 26 on this, while the latch 24 outside enclosing rocker is held on the side over the bearing blocks 31 protruding parts of the axis 26. The rocker 23 is presented by an attached to the axis 26 torsion spring in their the locking position of the bolt 24 enabling rest position, wherein the torsion spring 27 is supported with a spring leg on the rocker 23 and the other spring leg against a housing part.

The lying in the trough-like recess 15 folding handle 16 is pivotally mounted on the housing 14 via two respectively inserted from the outside bearing pins 32, each pass through an opening 33 in the housing 14 and a bearing opening 34 in the folding handle 16. To transmit the folding movement of the folding handle 16 to a movement of the rocker 23 a longitudinally displaceable in the housing 14 actuating pin 35 is provided, wherein the predetermined by the bearing pins 32 axis of rotation of the foldable out of the housing 14 folding handle 16 is arranged eccentrically to the displacement axis of the actuating pin 35, said to bridge this eccentricity on the folding handle 16, a lever arm 36 is formed. For sealing is provided in detail that the actuating pin 35 is sealed by a in a groove 40 formed on this trained seal 41 relative to the housing 14. As far as the folding handle 16 is also mounted in the housing 14 via two mounted in apertures 33 of the housing 14 bearing pins 32, 32 seals 42 are attached to the bearing pins, which provide for a seal of the folding handle or its storage relative to the Gehäus-, 14.

A folding out of the folding handle 16 from the housing 14 leads to a longitudinal displacement of the actuating pin 35, which thereby pivots the spring-loaded rocker 23. Since the rocker 23 is located with a lug 30 against the latch 24, the rocker 23 pushes the latch 24 against the action of the compression spring 25 in a position in which the latch 24 is released from the latch holder 28, so that the door leaf 10 can be pivoted away from the frame 12. After releasing the folding handle 16, the rocker 23 pivots back under the action of the torsion spring 27 acting on it back to its original position, thereby displacing the actuating pin 35, which in turn provides for the pivoting of the folding handle 16 in the recess 15.

The opening movement of the folding handle 16 is blocked in located in the closed position Vorreibverschluss 18 because the tongue 21 of the Cam lock 18 in its closed position, the rocker 23 engages below and thereby determines. Thus, the rocker 23 can not be pivoted so that due to the coupling of the rotational movement of the rocker 23 to the folding handle 16 by means of the actuating pin 35 and the folding handle 16 is blocked in its pivoting movement.

Since the latch 24 is arranged relative to the rocker 23 due to its independent storage on the axis 26 and thus can perform a pivotal movement even when blocked by the tongue 21 rocker 23, on the one hand, a snap function when inserting the door leaf 10 in the frame 12 also when located in the closed position cam lock 18 because the bolt abuts with its tapered locking surface against the bolt holder 28 and thus can pivot against the compression spring 25 until the latch 24 engages behind the bolt holder 28.

At the same time a safety function is thus realized, because the closure can also be opened from the inside of the door leaf 10 forth in the closed position located Vorreiberverschluss 18, for example, of persons who are inside a sealed with the folding handle closure container. For this purpose, it is only necessary to pivot the latch 24 by hand against the action of the compression spring 27 in its release position in which the latch 24 is released from the latch holder 28.

The features disclosed in the foregoing description, the claims, the abstract and the drawings of the subject matter of these documents may be essential individually as well as in any combination with each other for the realization of the invention in its various embodiments.
