Preferably subject to bending during receiving the body spring energy limiting the opening. are held. For this purpose, in the body limiting the opening, in accordance with the invention; of the doorway at least one leg elastically springing by the slamming of the door in a restricted position are available. In this case, the leg is preferably elastically bent. In addition the trunk or a leg limiting the opening, the moment or can be stretched.

The leg is preferably formed by an opening. During elastic movement, the angulation The angle may increase or decrease elastically as required. In addition, the leg is elastic can be bent.

In the opening limiting body; in a position where the door opening is limited, on impact; Having at least two spring sections that convert kinetic energy into spring energy is particularly preferred. These are similar or different in the slamming of the door. The body that can bend elastically, limiting the opening may have two legs.

The direction of the bending motion of the flexible sections, preferably with the axis of rotation, at least partially extends radially and/or parallel. Thus, this invention shows that the bending motion is circumferential. in the same direction as the braking force at the slamming of the door. differs from bodies that limit the familiar opening. limiting the openness in this way the body can be configured quite simply.

The first portion of the opening limiting body is preferably the angulation connected by a spring leg. is created with. The spring leg is in accordance with the invention, at least the transition to the first section It is located on a pedestal near it and is held at the opposite end of the first section.

The pedestal is part of the door. The spring leg is designed to limit the door opening in accordance with the invention. In a position where the door hits, it exerts a force on the base.

It is especially preferred that the leg is connected to the second part and held by it. is being done. Therefore, the second part functions as another pedestal.

The first part protrudes from the leg and part of the hinge fixed to the body grasps from behind.

The leg rests on a pedestal for at least approximately its length. This In this way, the forces applied on the pedestal are well distributed.

The first part and the leg may be of the same length or of different lengths.

The relative lengths of the first part and the leg, acting on the leg or first part determines the bending moments. The longer a section is, the further 0 is the distance to the pedestal. large and the bending moment is as large as 0.

The second section is preferably spring-formed and the body limiting the opening is attached to the door. It functions as the fixing part to which it is fixed. Therefore, the second part preferably it fulfills a dual function: on the one hand it serves as a fixed part In other words, when necessary, a bending axis passes through it. On the other hand it can also spring itself, in particular it can accommodate a bending inoinentiii.

The first part of the aperture limiting body is based on the axis of rotation in accordance with the invention. It runs parallel - for example vertically - and the second part is based on the axis of rotation. It extends diagonally—for example, horizontally. Essentially, the concept here, 20 It means a deviation up to 0”. However, the middle leg, for example, rotation inclined to the axis of rotation at an angle of 45° to 85°, preferably between 70° and 80°, to its axis extends.

For example, as a punch-/bending part made of a steel sheet, in particular, it can be produced from sheet steel. Its thickness is preferably 3-6 mm. This In this case the first section is preferably quite narrow for reasons of space. is being shaped.

Alternatively, the aperture-limiting body may be made of a round or plain cross-section, in particular a wire. It may be formed from an angle spring material having an element The wire diameter is preferably about 3 mm to 5 mm, preferably about 4 mm Aperture The extruder body should preferably be made of a high quality material such as chrome steel or chrome-nickel steel. made of steel. Strength and strength of the material; limiting the openness the forces generated by the slamming of the body, the door, about 0.1 to 3 mm, preferably 0.2 to 2 mm and more preferably 0.5 to 1 elastically deformed being measured.

Alternatively, the body limiting the opening, having a round or oval cross-section, It is also possible to form it from an elastically malleable plastic material.

In accordance with the invention, when the door slams, the leg is placed on a pedestal in a position limiting the opening of the door. It is domed away from a pedestal surface of the door, which functions as a door. In this case The leg, for example, rests on the support surface with one or both ends, while also resting the middle part of the leg. is bent and thus kinetic energy is converted into spring energy. support surface preferably formed in a connector described in more detail below.

In accordance with the invention, the support surface is parallel to the leg and thus obliquely to the axis of rotation. is aligned.

In the opening limiting position of the door, the body or body limiting the opening in the slamming of the door the force exerted on the door by its leg is at least partially in accordance with the invention. aligned parallel to the hinge's axis of rotation. In this way, force is an advantageous In this way, it is transmitted to the lower area of the door or connection piece.

In particular, these two bearing shafts have a plane perpendicular to the axis of rotation. at least essentially the mirror is placed symmetrically. Thus, both hinge elements It has the advantage of being used for both sides, in other words, it can be used both on the left and the left side of the body. It is also possible to connect the right side to the door. For this purpose, two bearing shafts are preferably one aligned on the line or parallel to each other and preferably have the same length.

The entire hinge member is essentially mirror-symmetric to a plane perpendicular to the axis of rotation. is particularly preferred.

The hinge element is preferably made of a flat material structure, in particular a sheet metal structure. is created. It is particularly preferred if the hinge element is formed from a steel sheet. is being done. Preferably high strength steel, eg chrome steel or chrome-nickel steel is used. The thickness of the flat material structure is preferably 3 mm to 7 mm, especially preferably about 5±1 mm°.

The hinge element is preferably punched from a steel sheet and then bent, such as It can be easily produced as a punch-/bending part. Thus, the assembly part support arm and bearing shafts can be formed in one piece. The hinge element is thus it can be produced cheaply and still have a high durability.

Preferably, a cross section of the support arm perpendicular to the axis of rotation has a curvature. This In the figure, a recess in the opening of the door is grasped by a side wall of the receiving chamber. is created; thus a greater opening angle can be achieved. it is designed in such a way that a large opening angle is possible. to get it hinge element, preferably allowing rotational movement of the side wall of the acceptance preparation of the door adapted as needed. Support arm, especially with mounting part, at a wide angle is being interleaved; so - with the mounting person - on the side wall in the door opening It covers a semi-circle to which it can turn. Preferably the mounting part and the support adjacent to it part of his arm is adapted to the shape of a semicircle as much as possible. for structural reasons therefore, the mounting part will usually be flat because it is fixed to the body of a household appliance. is designed to. The support arm is thus preferably more than 100°, more preferably 11° and apart from the mounting part, particularly preferably at a wide angle greater than 115 ±5°. is standing.

However, the support arm is preferably more than 90° in total, preferably more than 120° and it defines an arc or a curve, particularly preferably between 130° and 1500. In this way bearing shafts can be positioned close to the axis of rotation and have a wider opening angle it is possible.

It is especially preferred if the radius of curvature of the support arm is different along its length. is being done. The transition between different radii of curvature is preferably continuous so that the support The arm is particularly stable. Continuously variable radii of curvature in a hot bending process can be created. The radius of curvature of the support arm, preferably near the mounting increases continuously from a point to a certain point, and from there It is constantly decreasing up to a point.

On the support arm preferably adjacent to the mounting part, eg not substantially inclined or there is a first part slightly inclined and a second part adjoining the first part; where the first person and an end section adjacent to the second section form an acute intermediate angle.

This intermediate angle is less than 90°, preferably less than 60°, and more preferably between 30° and 50°. are available. The first part preferably has a total bend of less than 10° and in the second part preferably a maximum radius of curvature of about 5 to 15 mm are available.

In this way, with the door in a positive way is fixed. In the middle of the ring, the second part (34) is also attached with a screw (31).

One middle leg (33) of the body (30) limiting the opening is tilted against the spindle axis (3). oriented and likewise formed at the base (37) of the connector (7). extends along the support surface 36 .

In Figure 9, with the hinged door as in Figure 6°, the upper right corner of the refrigerator (1) perspective view is given. Contrary to the figure, the lower part of the bearing bolt (20) The eye (24) is taken in the bearing housing (23) in a rotating way. In this case, the clarity the first portion (32) of the limiting body (30) grips the support arm (12) from behind, and this Therefore, it is covered in Figure 9. The acceptance chamber (8) is with a cover strip (43) upwards. is covered.

However, in Figure 93, the cable duct in the bearing bolt (20) in the cavity of the door (2) A harness 45 routed through 21 is shown.

In figure 107, the perspective of the upper right corner of the refrigerator with the hinged door in the same way view is given, but here but without harness (45) and cover strip (43) has been removed. However, in Figure 10, plastic elements (40, 41 and 42) The panels of the hinge element created are shown.

In addition, in Figure 10, there is a protrusion into the space formed between the outer wall (5) and the inner wall (6). the lower part of the bearing housing (23) is displayed.

In Figures 11 and 12°, the door is open (Figure 11) and the door is closed (Figure 12). axis of rotation along the hinge element (10) together with the hinged door perpendicular sections are shown. The axis of rotation (3) is in any case, the bearing bolt (20) extends along its axis.

In the section images; The upwardly protruding section (19) of the bed trench (20) is a cut wiring harness (45) and mounting part (11) to the body of a household appliance (not shown) a screw (26) to which it is fixed can be seen. Possible coatings of the hinge element, better not shown for clarity. The body (30) limiting the opening is the part of the second section (34) It can be seen from the top, like the concave (35) where it is fixed.

As can be seen from Figure II; the first part (32) of the body (30) limiting the opening, it grips the back of the lever (12) and there it is in the opening-limiting position of the door, the second It rests in the region between the section (14) and the end section (15) of the support arm (12). This in the widely opened position, the half-wall (28) of the acceptance chamber (8) is supported by the curvature. Although it defines an arc of up to 135° along the dotted line (P), the sidewall (28) is bent so that it does not rest on the support arm (12) when the door is opened. especially large to provide an opening angle; The first part of the body (32) limiting the opening is also arranged in a space 52 of the body 30 in the wall 28; so great clarity It grasps the support arm (12) from behind, even at an angle.

In the closed position of the door shown in Figure 129, the inclined part (14) of the support arm (12), It extends into the pocket (39) formed on the wall (38) of the connection piece (7). Pocket (39) Thanks to this, the first part (13) is particularly long and the curvature of the second part (14) is particularly strong. It can be created as; this allows for a particularly large opening angle of the door. gives.

With reference to figures 13 and 149, the elastic movement of the opening limiting body is described in more detail. is explained.

In Figure 13, one part of the connection piece (7) on which the body (30) limiting the opening is located. section is shown. While the leg 33 is supported against the inclined support surface 36, the first the section is opened upwards over the bend (46). The second part (34), in the bend (48) opens from the leg (33) and is connected to the connector (7) via the screw (31) and thus fixed to the door.

The same pieces are also shown in Figure 14, in side view, in high sematic form; The portions (32, 33) and leg (34) of the trunk (30) limiting the opening are here only cut off. are shown as lines. The solid lines are the rest of the body (30) limiting the opening. represents the subject. The dashed lines are in the position where the door opening is limited. shows the state of the body (30) that it hits, which limits the opening. Then the support arm A force F1 is applied by (12) on the first division (32). Message in this way the kinetic energy is absorbed in the two spring segments indicated by Ri and R2 in Figures 13 and 14.

Depending on the distance from which the bend (46) acts on the first section (32) of the force F1, the first section (32) is springable in the Ri direction; here it bends in this direction. First As the section (32) is relatively short (about 5 to 10 mm), only a relatively small amount of is bent. In addition, the radius of curvature at bend 46 can also be elastically adjusted if necessary. can increase. The maximum deviation of the first segment (32) in the Ri direction is approximately 03 to 1 between mm. To provide sufficient space for this deflection, the upper portion 32 is It is separated from the section (51) by a slit. The width of the slit (e) is about 0.5 to 2 mm, preferably it is about 1 ± 0.2 mm°.

On the other hand, the leg (33) and possibly the second segment (34) are up in the direction indicated by R2. it is domed correctly. Here, the leg (33) is the bend (46) on the support surface (36). supported in the region; so that a force acts on the support surface 36, cf. Arrow (F2). In addition, the second portion 34 is transmitted to the dimple covering the ring in case of necessity. a pulling force acts. The relatively large length of the leg (33) (about 20-30 mm) visibly, for example about 0.2 to Zinm in the R2 direction It is domed in shape. In this case, the leg, and possibly the second part 34, is bent and thus it meets the spring energy. Also, the radius of curvature at the bend (48) and thus The inclination angle (48) can also be increased elastically, as can be seen in Figure 143.

The spring movements (Ri and R2) in Figure 14 are probably exaggerated. Door The forces occurring in the multiply are applied to the underlying inclined support surface (36) (force F2) and is transmitted to the concavity that closes the ring. In this way, the forces can prevent the connecting piece (7) from being damaged. It is distributed well enough to prevent it from seeing.

Thus, the invention flexibly meets the forces arising in the doorknob and thus providing an elastic door buffer that prevents an overload.
