Abstract

The refrigerator door hand grip (1-3) has the shorter of two arm levers (1,2) reacting on a plunger, moved in a guide acted on by a spring in alignment with its travel direction. The spring tension on the longer arm supports it on the end face of the carcass side wall. The two arm levers are located at a distance from each other, pivoting at the door. The arms are connected with each other by a contoured grip piece.

Description

The invention relates to a refrigerator or freezer with a handle having, hinged to a wall of the cabinet body door, which provided at its inner edge region with a circumferential, applied to the front side of the side walls and the bottom and top wall seal, wherein the handle a two-armed lever pivotally mounted about an axis parallel to the longitudinal edge of the door whose shorter arm acts on a guided in a guide, acted upon by a spring towards its retracted position ram acts on train on the longer arm on the front side of the Sidewall supported.

Refrigerator and freezer seals are usually made of elastomeric material with a closed, bellows-like hollow profile and a mounted on this strip of magnesiertem material, which, in order to ensure a good sealing abutment of the sealing profile on the front sides of the cabinet body, on one of the end faces of the cabinet walls attached strips of iron, which forms the anchor for the magnetic strip, applies. Since the opening of the door of the magnetic strip attached to the seal must be torn off a large area of the iron strip, a considerable force is required to overcome the magnetic clamping force. Additionally arises in freezers after closing the door by freezing the moisture during the opening time in the freezer ambient air reached a negative pressure, which sucks the freezer door with great force against the front sides of the cabinet body, so that the freezer door can be opened for a certain time after closing only with considerable effort. In order to open the refrigerator or freezer door, it is therefore often necessary to pull on the handle with greater force or jerky, which is not only annoying, but can also lead to an undesirable dislocation of the refrigerator or freezer as a whole.

From EP 0 598 979 A1 a refrigerator or freezer of the type described is known in which due to the lever translation, the plunger with great force pulls the door from the cabinet body, so that the locking forces acting on the seal are overcome. A disadvantage of this known refrigerator or freezer, however, is that the plunger acts with high surface pressure on a small area of the end face of the cabinet body, so that it can come to deformations and damage in this area.

The object of the invention is therefore to provide a refrigerator or freezer of the type described, in which the door with large opening force can be deducted from the cabinet body, but without excessively large surface pressures are exerted on small areas of the end face of the cabinet body.

According to the invention, this object is achieved in that two two-armed lever are pivotally mounted on the door at a distance from each other, whose longer arms connected by a parallel to the longitudinal edge of the door handle bar.

Due to the inventive design of the door handle is achieved that the pulling off the door of the body part forces are applied by two mutually parallel rams, so that the forces acting on small areas of the front of the cabinet body pressure forces halve and thus the risk of unwanted damage or Deformations avoided, or at least reduced.

According to a preferred embodiment it is provided that the handle bar is integrally formed with the longer arms material homogeneous. This one-piece design can be created in that the handle bar is made with the levers of a one-piece plastic injection molded part.

The handle bar expediently consists of a plastic injection-molded part hollow-injection-molded in the gas pressure process.

According to another embodiment it is provided that the handle bar with the longer arms is connectable. In this way, the handle bar according to the height of the door can be formed arbitrarily long. The connection can be effected by a plug and / or locking connection.

With the door holding parts can be connected, which are provided with bearing bores for receiving the pivot axis of the lever.

In order to prevent damage to the door handle during transport and to allow a space-saving transport of refrigerators or freezers, it is desirable that the door handle can be applied close to the door. In a further embodiment of the invention it is therefore provided that the bearing bores consist of mutually partially overlapping bores, the non-overlapping parts merge into each other by gusset-like recoveries, and that the holding parts and the lever are provided in the manner with stops that when pressing the longer Lever arms against the door, the pivot axes of the one hole parts on the gappy recesses in the other bore parts enter. According to this embodiment of the invention, therefore, a displacement of the pivot axes of the two-armed lever takes place by simply overpressing, wherein the pivot axis again passes into the other bore part by renewed removal of the door handle of the door and thereby assumes the door handle its usual position of use.

Conveniently, each two-armed lever, starting from the handle bar has a U-shaped cross-section, wherein the pivot axis consist of on opposite inner sides of the legs of the U-shaped part attached journal, which can be latched into the holes of the holding parts.

According to another embodiment, it is provided that the plunger have in cross-section C-shaped profiles and are guided on fixed to the front side of the door rails with Z-shaped angled sides.

The rails, which are preferably made of sheet steel, may have bent ends to which holding parts made of plastic are injected. According to a further embodiment, it is provided that the lever is provided at its end projecting over the door with a curved bearing part, which surrounds the approximately complementary shaped outer end of the plunger to form an articulated connection. In this embodiment, the handle appears in the front view of the door with uninterrupted outer surface, because the gap connecting the handle with the plunger is visible only in the side view of the door.

Conveniently, each ram is provided at its end wall of the cabinet body end facing with a buffering cap made of elastomeric material, which ensures a gentle attack on the end wall.

Conveniently, the ram guide is covered by an attached cover part, so that a good appearance is created by this panel.

Between the holding part and the handle part a return spring is suitably clamped. This return spring may consist of a bent Blattfeder..oder a leg spring or a compression spring.
