Description

The present invention relates to a door handle for opening a refrigerator or Freezer compartment door with a slide displaceably mounted on the narrow side of the door, pushed to press the door against a door frame or device body is, as well as one provided on the front side of the door, hinged with the slider connected handle for actuating the slide and pulling the door, wherein for the handle arranged on the outside of the door pivot bearing is provided, by means of which the handle relative to the door between a Aufund a to-position is pivotable.

The main function of a lever handle for refrigerator or freezer doors is the light and low-energy opening of the respective door. It is the locking force of the Magnetic seal such doors and especially in freezer doors the high Suction power created by the freezer vacuum as a result of air cooling can, overcome. It has therefore already been suggested that doors not only to open by acting on the handle traction, but the handle pivotally mounted on the door and a swivel gear with a slider to connect, which presses against the door frame or the device body to the door impose. The corresponding pivoting movement of the handle is doing with a certain gear ratio transferred to the slider, so that the For opening forces required to be applied via the leverage. However, a disadvantage of such pivot lever door handles with push-pull is regular the size. In particular, the transmission mechanism requires between Handle and slide an increased height so that the door handles on the outside of the door apply strong and look little elegant. In addition, with such door handles often the assembly consuming, insofar as the usual mounting screws can not be placed arbitrarily due to the transmission mechanism.

The present invention is based on the object, an improved door handle of the type mentioned avoids the disadvantages of the prior art and the latter develops advantageously. Preferably, a flat-building, elegant door handle, which is easy to assemble and the door with less Force to open.

According to the invention this object is achieved by a door handle according to claim 1 solved. Preferred embodiments of the invention are the subject of the dependent Claims.

The door handle is thus characterized according to the invention in that the pivot bearing defines a Momentandrehpol for the handle, the at least for one Part of the pivoting movement of the handle between open and closed position on the Inside the door is located. Although the door handle is arranged with one on the outside of the door Swivel bearing is articulated on the outside of the door, is the instantaneous pivot or the pivot center of the door handle on the inside of the door or within the outer skin of the door, on which the door handle and its pivotal mounting are attached. The Momentandrehpol lying on the inside of the door allowed a low overall height of the entire door handle, with a sufficient travel the slider reaches without excessive pivotal movement of the handle can be.

In particular, the pivot bearing can be designed such that the instantaneous rotation the handle during its movement between open and closed position moved on a path that is preferably entirely on the inside of the door, but in particular at least in the pivoting range of the door handle, in which the Slide pushes against the counter flank of the device body, on the inside of the Door is located. In contrast to known solutions, the handle therefore has no door locks Pivot axis. Rather, the Momentandrehpol the door handle moves its mounting on a track, with the instantaneous pivot but on the inside the outer door skin is held. This allows for different Pivoting positions of the door handle favorable leverages in the implementation of Handle movement can be achieved in a slider movement.

In a further development of the invention, the handle is pivotable on a coupling member hinged, which in turn pivotally mounted on the door front or attached thereto Door fitting is articulated. About this coupling link is on the inside lying Momentandrehpol and a cheap power transmission at low Height achieved. In particular, the coupling element may be directly, i. without interposition further coupling links, on the door front or attached thereto Fitting part to be rotatably mounted, so that the pivot axis of the coupling member is door-open. The handle is preferably directly without interposition further gear members pivotally attached to the coupling member. Especially It is advantageous here, if between the handle and the coupling member a detachable snap connection is provided. This simplifies the assembly.

In a further development of the invention, the handle is just as directly without interposition of transmission elements pivotally connected to the slider, wherein preferably the connection between the handle and the slider releasably, in particular is designed in the form of an articulated snap-in or latching connection. This not only facilitates the assembly, but it allows, above all, the If necessary, simply uncouple the slide from the handle and disassemble it to make the lying under the slide door handle parts accessible. Especially the slider can form a mounting screw cover, allowing a separate Cover the fasteners of the door handle on the door can be omitted. To attach the door handle to the door, the door handle a mounting plate own, on which both the slider and the handle can be stored. The said mounting plate itself is by suitable fastening means, in particular screws, can be mounted on the door, wherein in an advantageous embodiment the invention, the fastening means arranged exclusively on the narrow side of the door are so that they can be covered by the slider. Will the Slider released from the handle and dismantled, the fasteners are accessible, to be able to release the mounting plate from the door.

To the door handle, more precisely the handle sufficient stability over To give cross-strains that may possibly arise because of a child Hanging on the handle, the mounting plate forms a guide in which the handle is included and the handle in addition to its storage on the slider and stabilized on the coupling member. In particular, the mounting plate two to the pivot axis of the handle have vertical guide surfaces, between where the handle is received with corresponding guide surfaces. moreover the mounting plate can be a around the pivot center of the handle around curving guide surface along which the handle runs along.

To give stability to the entire door handle with respect to the attachment to the door can in the invention an anchor plate under the outer skin of the door in these are lying on the narrow side of the door to be foamed. In this anchor plate The fastening screws can be screwed in, with which the mounting plate for the handle and the slider is attached.

In development of the invention is an adjustment for adjusting the position the handle provided in the closed position relative to the door. Often fits due of mold tolerances of the door the door handle does not exactly match the outer contour of the door Door. In particular, the handle with its freely projecting end in the closed position stand flush on the front of the door. With the help of the mentioned adjustment device The handle can be precisely adjusted until the cantilevered end of the handle rests exactly on the outer door skin.

The adjusting device can in particular the angular position of the mounting plate set relative to the door. Preferably, one on the narrow side of the Door arranged, provided against the narrow side pushing adjusting screw be.

The door handle shown in the figures comprises a plate-shaped fitting part 1, has two legs bent to each other, so that the fitting of two Pages on the door 2 is settable. As Figure 4 shows, is a first leg 3 of the fitting part 1 on the narrow side of the door and a second leg 4 on the front the door can be set. The fitting part 1 is thereby by means of four fastening screws 5 bolted to the door. All four mounting screws 5 are on the provided first leg 3 and in the narrow side of the door 2 can be screwed. In the Door 2 is foamed for reinforcement an anchor plate 6, which is immediately behind the outer skin 7 of the door 2 lies on the narrow side thereof (compare FIG. The fixing screws 5 are screwed through the outer skin 7 into the anchor plate 6.

The exact position of the fitting part 1 is adjustable by an adjusting device 8, which in the illustrated embodiment comprises two adjusting screws 9, the are also screwed in the first leg 3 of the fitting part 1 and against Press the narrow side of door 2. As Figure 4 shows, can by screwing the Adjusting screws 9, the angular position of the fitting part 1 are fine adjusted. In the drawn embodiment, an angle to the narrow side of 2 ° is set. It is understood that other angles can be set here. through the adjuster 8, the position of the fitting part 1 is adjusted so that the Handle 10 rests with its free end 11 on the front side of the door 2. The adjustment device 8 can be designed differently. It is advantageously formed so that it the angular position of the entire door handle to a parallel to the front of the door and substantially to the longitudinal direction of the handle can change vertical pivot axis.

On the fitting part 1, a slider 12 is slidably mounted, with the aid of which Door can be forced economically. The slider 12 is on the narrow side arranged the door 2 and on the door narrow side leg 3 of the fitting part 1 slidably guided. As Figure 6 shows, the leg has 3 of Fitting part 1 two longitudinal guide means in the form of longitudinal webs or longitudinal grooves 30, in which the slider 12 with complementary longitudinal grooves or longitudinal webs 31st is used. The slider 12 is parallel to the door narrow side substantially displaceable perpendicular to the plane of the door 2.

As Figure 4 shows, the slider 12 is in the closed position of the handle 10 on the Inner contour of the door 2 and extends in the region of the magnetic seal 13 back to the door frame forming contour of the device body 14. In the closed position is the slider 12 with its front side or its print head 12a not on the Device body 14 on.

The slider 12 can be actuated by the handle 10, for this purpose is pivotally mounted on the fitting part 1. More specifically, the handle 10 on the one hand hingedly connected to the slider 12, and on the other hand pivotally hinged to the fitting part 1. As FIG. 4 shows, the articulated connection 15 is between the handle 10 and the slider 12 is formed as a releasable snap connection. The handle 10 and the slider 12 have complementary latching means in the form of a resilient, fork-shaped socket with a groove-shaped Recess and a complementary bead-shaped joint head (see Figures 5 and 7). The hinge axis 16 to which the handle and the slider relative are tilted to each other, extending perpendicular to the sliding axis of the Slider 12 and substantially parallel to the narrow side of the door.

On the other hand, the handle 10 is spaced from the hinge 15 at the second leg 4 of the fitting part 1 hinged on the front side of the door, and although by means of a coupling member 17 which is rigid and in turn pivotally hinged to the leg 4 of the fitting part 1. Like FIG. 4 shows, the coupling member 17 to a substantially vertical pivot axis 18 at the leg 4 rotatably mounted. In the illustrated embodiment is a fastening part 19 is provided, which carries the pivot axis 18 and on the leg 4 is screwed, by means of a fastening screw 20 (see Figure 2 and 3). The pivot axis 18 is located substantially directly on the front side of the Door or the leg 4 of the fitting part 1 attached thereto.

With its other end, the coupling member 17 is pivotally connected to the handle 10th connected, wherein the hinge joint 21 also as a releasable snap connection is trained. The pivot axis defined by the hinge 21 between the handle 10 and coupling member 17 is parallel to the pivot axis 18th

The pivoting of the coupling member 17 is characterized by stops 22, 23 with respect limited to the fitting part 1, wherein the stops 22, 23 on the fastening part 19 are realized (see Figure 2, 3). It goes without saying, however, that others too Pivoting limits are possible.

As FIG. 3 shows, the arrangement and design of the coupling member 17 are made in such a way that that the coupling member 17 with its longitudinal axis substantially perpendicular extends to the front of the door 2 when the handle 10 in its up position is. When the handle 10 in its rest or closed position according to FIG is, the coupling member 17 extends with its longitudinal axis at an acute angle of the front of the door, tilting towards the free end of the handle 10 is (see Figures 2 and 4). In order to achieve a low-level arrangement, extends the coupling member 17 in the interior of the handle 10. The hinge connection 21 is located substantially directly on the inside of the front forming Wall of the handle 10 (see Figure 4).

The arrangement of the coupling member 17 and its orientation relative to the hinge connection 15 of the handle 10 on the slide 12 are made such as figures 2 to 4 show that the instantaneous turning pole 24 and the pivoting center point, respectively the handle 10 to which it is effective to pivot relative to the door, on the Inside the door 2 is located, although the entire pivot bearing on the outside the door is attached and arranged. This allows on the one hand a very flat height and on the other hand favorable ratios to the movement of the Handle and the forces acting thereon in a movement of the slider 12 and to enforce the forces imposed by this.

As shown in FIGS. 1, 5 and 6, this is for stable mounting of the handle 10 not only via the coupling member 17 and the hinge connection 15 on the slider 12, but also mounted on guide surfaces on the fitting part 1. The fitting part 1 has, as Figure 6 shows, two parallel to the pivot axis of the handle 10th vertical guide webs 25, between which the handle 10 is received. The handle 10 in this case has corresponding guide surfaces 26 (see Figure 5), with which he slides on the insides of the guide webs 25. In addition to that Fitting part 1 a around the pivot center of the handle 10 around curving Wall surface 27 (see Figure 4) provided which a gap formation between prevents the fitting part 1 and the handle 10 when the door handle in the open position located.

As FIG. 4 shows, the articulated connection 21 is located between the handle 10 and the handle Coupling member 17 designed so that of the coupling member 17 train on the handle 10th can be transferred. The coupling member 17 acts as a tension member, which on the Handle 10 exerted tensile force in a compressive force on the slider 12 converts.

In order to dismantle the door handle, the snap connection 15 between the slider 12 and the handle 10 is released so that the slider 12 withdrawn and can be dismantled. On the one hand, this makes the fastening screws 5 and on the other hand, the adjusting screws 9 accessible.
