Definitions
- the invention relates to a refrigeration device with a device housing composed of at least two housing parts, including a body and at least one door, which encloses a heat-insulated interior, and with a door safety device that counteracts an axis on a first of the housing parts Restoring force pivotally mounted locking part and a projection attached to a second of the housing parts, which interacts with the locking part.
- a refrigerator with such a door lock is known from DE 101 17 782 A1.
- Refrigerators with a body and with at least one door are usually equipped on their doors with a circumferential magnetic seal, which closes the interior largely airtight when the door is closed and, moreover, the door is closed by a magnetic force acting between the seal and a door frame on the body Holds position.
- the range of this magnetic force is very short. It can therefore not be reliably avoided that the door does not completely close, but remains open a crack without this being conspicuous to the refrigerator from the outside.
- This problem is particularly troublesome for refrigeration appliances with two or more doors that do not seal air-tight interiors.
- these interiors can e.g. B. a freezer and a refrigerator compartment of a combination refrigerator, or a refrigerator compartment and a so-called basement compartment, which is kept at a higher temperature than the refrigerator compartment and may only be cooled by air exchange with the refrigerator compartment.
- a door is slammed in such a device, the resulting pressure surge can cause the other door to open, unless there is a safety device that prevents this by exerting a force that supports the magnetic seal on the closed door, that keeps the door closed.
- such a securing device is formed by the projection and the spring-loaded locking part, which exerts a force in the closing direction on the door when it is closed and on the latter when the door is opened Projection is displaced against the restoring force of the spring.
- the locking part is mounted in a housing shell attached to the body in a bearing pivotable about an axis.
- the shaft of the locking part is mounted crossing one side surface of the housing part carrying it, considerable forces acting on the shaft can be introduced into the housing part, whereby a housing shell is relieved and the requirements for the mechanical strength of the housing shell are reduced.
- the housing shell could even be omitted completely, since it is no longer necessary as a bearing for the locking part.
- a section of the shaft engaging in the housing part of the refrigeration device is preferably received in a shaft projecting from a wall of the housing part into the housing part in order to give the shaft a stable hold.
- the shaft is preferably formed in an end profile which forms the upper or lower flank of the door. In an end profile molded from plastic, the shaft can be formed in one piece without effort.
- the locking part is attached to a flank of the door, it can be placed behind a decorative plate of the refrigerator, so that it is closed when the door is closed is not visible. An aesthetic impression of the refrigerator is not affected by the latch part.
- a restoring force for the locking part can be generated by a spring.
- the spring is a compression spring.
- the spring does not affect opening or closing of the door.
- Such a torsion spring can be, for example, a coil spring or a spiral spring. The main advantage of this configuration is a space-saving design.
- the shaft can be a screw. Thanks to its thread, it can be quickly and easily attached to one housing part.
- the basic embodiment of the invention does not necessarily require a housing, it can nevertheless be advantageous to provide a housing in which the locking part is hidden. With the housing, for example, undesirable external influences from the locking part can be rejected. For these very reasons, it can also be advantageous to provide the spring also received in the housing.
- the housing can preferably be mounted on the door in two orientations rotated by 180 ° relative to one another, each adapted to the selected stop.
- a housing can expediently be composed of two half-shells that are mirror images of one another.
- the projection preferably has two inclined surfaces facing away from one another for interacting with the locking part.
- the locking part is first pushed back by sliding on one of the inclined surfaces on the projection, while the locking part is then pressed by the restoring force against the second inclined surface, on which the locking part slides, which drives the door towards full opening.
- the situation is reversed for a closing movement.
- that of the inclined surfaces which touches the locking part when the door is closed is preferably arranged at a greater angle to the direction of movement of the door than the other inclined surface.
- the projection can be formed, for example, by a tab protruding from the body.
- the tab can be, for example, a bent end section of a sheet.
- the projection is advantageously fastened to a door bearing attached to the body, because the same fastening means can then be used for the projection and door bearing. No additional fasteners or holes in the body are required.
- the locking part in turn also preferably has two inclined surfaces facing away from one another for interacting with the projection.
- the one of these inclined surfaces, which touches the projection when the door is closed, is preferably arranged at a larger angle to the direction of movement of the door than the other inclined surface.
- Fig. 3 projection and bolt part in cross section during the opening or closing of the door
- FIG. 4 projection and bolt part in cross section with the door open.
- a part of a refrigeration device according to the invention is shown, in which a door lock 1 can be seen in cross section in plan view.
- a part of the front of a body 2 and a door 3 of a device housing of the refrigerator can be seen in a closed state.
- the door 3 is pivotally attached to the body 2 by means of a door bearing 4.
- the door bearing 4 is a metal fitting and comprises a flat strip, which is attached to the body 2 by means of screws 5, and an arm which is angled from the strip and carries an upright cylindrical pin at its free end, which extends into a bore in the door 3 intervenes and thus defines their pivot axis.
- the door lock 1 comprises a plate 6, a locking part 7, a spring 8, a housing 9 and screws 10 and 11.
- the plate 6 is fastened to the body 2 together with the door bearing 4 with the same screws 5.
- An end section of the sheet 6 is bent as a tab 12 projecting from the body 2.
- the tab 12 has two inclined surfaces 13 and 14 facing away from one another and forming an angle.
- the sloping surface 13 facing the body 2 intersects a line N, which is perpendicular to the front of the body and corresponds to the direction of movement of the door when opening, at an angle ⁇ of approx. 60 °, the inclined surface facing away from the body at a smaller angle ß of approx . 20 °.
- the locking member 7 is pivotally attached to the door 3 about a vertical axis, as indicated by the double representation of the locking member 7, once in contact with the tab 12 and once in the pivoted-back position.
- the locking part 7 also has two inclined surfaces 15 and 16 which face away from one another and form an angle. In the illustrated closed state of the door 3, the inclined surface 15 of the locking part rests parallel to the inclined surface 13 of the bracket 12.
- the housing 9 With the screw 11 and the screw 10, the housing 9 is attached to the door 3.
- the locking part 7 is hidden within the housing 9.
- the spring 8 is also received by the housing 9. It engages on the bolt part 7 and the screw 11.
- the spring 8 is supported on the screw 11 and exerts a restoring force on the pivotable locking part 7, which pushes the door 3 against the front of the body 2 and thus prevents the door 3 from opening unintentionally.
- 2 shows a cross section through an upper region of the door 3 and the parts of the door lock 1 mounted on the door, which cross section extends through the locking part 7, the housing 9 and the screw 10.
- a front plate 21 and a rear wall 22 of the door 3 delimit a space filled with insulating material, which is closed at the top by an end profile 17, which is placed on the upper edges of the front plate 21 and the rear wall 22.
- a shaft 18 projecting from the intermediate space is formed in one piece on the end profile 17.
- a threaded section 20 of the screw 10 is screwed into this shaft 17.
- a portion 19 of the shaft of the screw 10 near the head passes through two bores of the housing and serves the locking part 7 as a shaft about which the locking part 7 can be pivoted.
- a second shaft (not shown) in the end profile 17 is used to fasten the screw 11 to the door 3.
- the housing is composed of two half-shells 23, 24, one of which is the mirror image of the other.
- a recess 25 on the top of the upper half shell receives the head of the screw 10.
- a corresponding recess, not shown, is provided for receiving the head of the other screw 11.
- Recessively opposite recesses 26 of the lower half-shell are provided in order to receive the heads of the screws 10, 11 when the hinge of the door 3 is not mounted on its right edge, as shown in FIG.
- Fig. 3 shows a situation during the opening of the door 3.
- the door 3 swings away from the body 2.
- the shaft 19 of the locking part 7 firmly anchored to the door 3 follows this movement.
- the locking part 7, the inclined surface 15 of which initially contacts the inclined surface 13 of the tab 12, is pivoted about the screw 10 against the resistance of the spring 8.
- the inclined surface 15 of the locking part 7 slides on the inclined surface 13 of the tab 12. Due to the large angle ⁇ , the spring 8 is strongly compressed; so that a fairly large force is required to open the door 3.
- Fig. 2 is a moment immediately after the inclined surface 15 is in contact with the inclined surface 13 has lost to see.
- Fig. 4 shows the situation at the moment when the locking part 7, now swung out again by the restoring force of the spring 8, detaches from the tab 12.
