Description

The invention relates to a closure for refrigerators with an outside handle a cold room door-mounted outer handle, which is movable between a closed position and an open position, an on the inside of the refrigerator door anordbaren inner handle, which is connected by a connecting member with the outside handle and emergency release relative to the outside handle is limited movable together with a closing element, and with an attachable to the door frame closing part.

Closures for cold rooms, especially for fresh food and freezer cells, of the type described above are known. From the outside, these refrigerator doors are actuated by means of the outer handle, which is movable between a closed and an open position. This movement is usually a rotational movement taking place through a twist angle of 90 °. However, other movements are possible, leading to an open and closed position. From the inside, the refrigerator door is actuated by an inner handle, which is connected by a connecting member with the outer handle and consequently at the same time follows its movement between the closed and open positions. For the purpose of an emergency release, the inner handle can be moved relative to the outer handle together with the closing the refrigerator door in the closed position closing element limited so that the refrigerator door despite closed outside handle can be opened from the inside, since the closing element connected to the inner handle a arranged on the door frame closing part releases.

In the known refrigerator closures, the handles must be selectively moved between closed and open position when the door should be opened or closed. In the open position, the refrigerator door is not held on the door frame, if the handles have not been transferred to the closed position. This often leads to open or semi-open positions of the door, which is associated with considerable energy losses.

The document GB 596 030 A discloses a closure with the features of the preamble of claim 1. Furthermore, the closure of this document on a closing element, which can be positioned by means of the outer handle in two different positions relative to a closing part, wherein the closing element in the one position, the function of a locking bolt corresponds, and fulfills the function of a spring-loaded latch or latch in the other position, although although the closing element on the closing part kfraftschlüssig is fixed, but the door can be pressed or overcome by overcoming a predetermined force.

The invention has for its object to further develop a closure of the type described above such that the construction is simplified.

The solution of this problem by the invention is characterized in that the closure has an additional, a spring-loaded latch (11) containing, closure element (8b), wherein the closure element (8b) in the open position of the outer handle (5) on the closing part (4). the door frame (1b) can be secured in a force-locking manner, the additional closure element (8b) being arranged on a ring (8) which also contains the closing element (8a) which is effective in the closed position, the ring (8) being connected via an outer tube (7). with the outer handle (5) is rotationally connected.

Due to the development of the invention, there is the possibility to reliably close the door in the open position of the handles without affecting the other functions of the refrigerator compartment closure by the spring-loaded case of the additional closure element engages behind the closing part of the door frame frictionally. The door can thus be easily pushed or pulled while overcoming a predetermined force. This makes it possible in a simple manner to set the refrigerator door in the open position of the handles on the closing part of the door frame, this determination can be opened or closed by applying a previously determinable force on the door.

According to the invention, the additional closure element may be arranged on a ring which also contains the closing element which is effective in the closed position.

The case contained in this additional closure element is preferably formed either as a spring-loaded roller or ball or as a spring-loaded member having a Zudrückschräge and also inclined support surface.

In a preferred embodiment of the invention, the outer handle is mounted on the cold room door by means of a bearing ring which has a latch opening for an operable by a arranged on the outer handle lock lock. Hereby, a simple storage and locking of the refrigerator door is achieved. If the inner handle is also mounted on the refrigerator door by means of a bearing ring which has at least one stop which limits the pivoting of the inner handle, also results with respect to the inner handle a reliable storage, wherein the bearing ring additionally contains the Schwenkwegbegrenzung.

According to a further feature of the invention, the ring containing the closure element and the additional closure element is attached to the inner handle. This results in a further simplification of the construction, since both the closing element and the additional closure element are arranged on one and the same component, which is fastened to the inner handle, so that a driving of the closing element by the inner handle with closed outer handle in a simple manner possible , The connecting member is in this case preferably formed by two concentric tubes, of which the outer tube is a fixed connection between the handles, whereas the inner tube can perform the closing part by the closing element releasing relative movement.

In the drawing, an embodiment of the refrigerator closure according to the invention is shown, namely shows:

a perspective of the closing element and the additional closure element containing ring.

The Fig. 1 shows on the basis of a horizontal section a direction indicated by two wall parts of the refrigerator 1, which is provided with a cold room door 2. The refrigerator door 2 is hinged on one side by means of Fitschen 3 on the wall part pivotally. The other wall part is provided with a closing part 4, on which the refrigerator door 2 can be fixed by means of the closure, as an exemplary embodiment in the FIGS. 2 to 4 is shown.

The Fig. 2 shows an outer handle 5, which is arranged on the outside of the refrigerator door 2 and an inner handle 6, which is arranged on the inside of the door. This outer handle 5 is rotationally connected via an outer tube 7 with a ring 8. The ring 8 has a cooperating with the closing part 4 closing element 8a and an additional closure element 8b, which also cooperates with the closing part 4 in the open position of the handles 5, 6.

In Fig. 3 the inner handle 6 is shown. At this inner handle, the ring 8 is mounted rotatably limited by a predetermined angle of rotation. For this purpose, the inner handle 6 is provided with an inner tube 9 concentric with the outer tube 7, which has two spaced-apart stops 9a. With these attacks, the inner tube engages a driver, not shown, which can be actuated by the lock 10 in the outer handle.

While the handles 5 and 6 are pivoted together when the lock 10 is not completed, a pivoting movement is possible by turning the inner handle 6 with the lock 10 and thus fixed outer handle 5, in the end position, the closing element 8a releases the closing part 4 located on the wall part, so that even with the outer handle 5 closed, the refrigerator door 2 can be opened by an emergency release.

Like from the Fig. 2 to 4 shows, the closing element 8a is formed integrally and rigidly on the ring 8. The additionally formed on the ring 8 closure element 8b forms a housing into which a case 11 against the force of at least one spring 12 can be inserted. In the embodiment shown in the figures, the case 11 is formed with a Zudrückschräge 11a and on the other side with a likewise extending obliquely to the direction of support surface 11b. The case 11 can thus overcome the of the spring 12 applied spring force when closing the door upon contact with the closure member 4 are pushed back into the housing of the closure element 8b. Once the case 11 is behind the closing part 4, it is pushed out due to the spring force and holds the refrigerator door 2 in the open position. Now, if a tensile force is exerted on the case 11, this is in turn moved beyond a predetermined amount on the inclined support surface 11b in its housing, so that the refrigerator door 2 can be opened. In the open position of the handles 5 and 6 thus the refrigerator door 2 is held in the closed state; Opening and closing the refrigerator door 2 is possible at any time after overcoming the spring force.
