DE1022118B - Closure, especially for refrigerators - Google Patents

Description

The invention relates to a closure for refrigerators od. The like. With one on one of a force storage spring loaded pivot lever pivotable seated fork latch.

It has already been proposed to design a power accumulator-operated lock equipped with a fork latch so that after the latch engages the latch in the locking bolt with a lever-operated tightening of the door, the elastic spring also acts as an element exerting the tightening force is used. Here, the fork latch, which is designed with supporting surfaces , is pivotably mounted on a pivot lever, against the end of which the force storage spring is supported. To lock them in the tensioned state, a support lever is used, which is supported against a stationary support bolt.

Furthermore, it has already been proposed that a closure for refrigerators with a die Movement of the fork latch triggering energy storage device to support the pivotable fork latch directly on a stationary support bolt.

In these embodiments, both for releasing the lock and for cocking the Energy storage device, which takes place by closing the refrigerator door, requires a considerable amount of force necessary. It is therefore not possible to use very strong energy stores.

The invention now aims to design a refrigerator lock in spite of the great energy storage effect, that the same works smoothly and, in particular, snaps softly when it is triggered, so that a comfortable but reliable opening and closing is achieved, and with this a clinking effect Cabinet contents are avoided.

For this purpose, according to the invention, the fork latch has one on the other side of the latch pivot pin extending trap tail, which is provided with three angled support surfaces, two of which are supported against a stationary stud bolt and one when opening pivotably mounted bolt acts.

So that this lock is also foolproof, i. H. playing with the fork latch does not trigger it is easily brought about, are in the open position of the closure according to the invention the shorter Leg of the fork latch in the direction of the pivoting movement in front and the longer, a leading edge for fork legs carrying the locking bolt pin behind the connecting line of support bolts and Latch pivot point, whereby the longer fork leg does not protrude from the cuff.

actuation according to the invention to the stud bolt under the influence of a spring rocker arrange pivotably mounted on the one hand the

ao extension of the pull handle is effective and the other hand is provided with the stop bolt acting against the support surface of the latch tail.

In order to achieve a favorable catching effect of the trap, the longer one is also according to the invention Fork legs with a run-up edge for the locking bolt pin protruding in front of the fork slot educated,

An exemplary embodiment of the invention is shown in the drawing. It shows

Fig. 1 the closure in the closed position partially cut,

Fig. 2 the lock in the open position and
Fig. 3 shows the lock when the door pull handle is operated.

The housing of the lock consists of one attached to the pull handle bearing plate 1 by means of the bolts 2. U-shaped folded lock plate 3. Between the legs of this profile piece is the pivot pin 4 used around which the lever 5 is pivotably mounted.

The fork latch 6 is arranged directly on the pivot lever 5 by means of a pin 7. she owns an outer, shorter fork leg 8 and an inner, longer fork leg 9. which both limit the fork slot 10, which is curved concentrically to the pin 7.

The fork latch 6 has a fork tail 11 which has support surfaces at an angle to one another 12, 13 and 14 is provided.

A stop pin 15 is provided on the arm of the pivot lever 5. The energy storage spring 16 is supported with its one end against an angular shoulder 17 of the pivot lever provided with a retaining pin 5 while the other end is against you

also provided with a retaining pin supporting projection 18 of the housing 3 applies. A stationary stud bolt 19, which is preferably provided with a roller, is arranged between the legs of the profile housing 3. According to Figs. 2 and 3, the latch tail 11 rests against this acting stop bolt 24 is provided. The locking block 25 attached to the door frame has a pin 26 which, when the refrigerator door is closed, strikes against the fork latch leg 9 (see FIG. 2) and the fork latch 6 pivots. c The pin 26 is caught in the fork slot IQ. As soon as the support surface 13 of the latch tail 11 slides off the stud 19 during this pivoting, the tensioned force storage spring 16 pushes the pivoting lever 5 into a position similar to FIG. 1. Here, the fork latch 6 pulls the locking block 25 into the lock. Depending on the size of the pull-up travel, the force storage spring 16 still has a certain tension force which, according to the invention, can now be used for resiliently pressing the door. The fork latch 6 lies with the leg 9 against the bolt 15 so that it is held in a locked position by the bolts 15 and 19. In the open position, the back of the fork latch 6 lies against the pivot 4 under the action of the force storage spring 16. The door is opened by a pull handle 23. If the latter is pivoted out as shown in FIG Stud 19. Here, the stop bolt 24 steps against the support surface 14 of the latch tail 11. The pivot lever 5 is raised while the force storage spring 16 is compressed, the latch 6 rotating about its pin 7. The locking pin pin 26 slides out of the fork slot 10 as a result of the pivoting movement of the latch. When the pull handle 23 is released, it is pivoted back, and the spring 20 also moves the rocker 21 back into the basic position according to Fig. 1. It can be seen from the figures that in the open position of the lock (Fig. 2) the shorter leg 8 of the Fork latch 6 lies in the direction of the pivoting movement in front of the connecting line xx of the support bolt 19 and the latch pivot point 7, while the longer fork leg 9 lying behind this line in the direction of the pivoting movement does not protrude from the cuff. As a result, a pressure on the leg 8 slightly protruding over the faceplate does not trigger the energy storage mechanism. Ρλτε ν τ α ν s ρ ι; ν cue-. 1.
