Abstract

In the case of a refrigeration device, in particular a household refrigeration device, with a storage chamber (3) and at least one refrigerated goods carrier (5; 6) supported on projections (19) from side walls of the storage chamber (3) and displaceable parallel to the side walls, a transport lock (37) comprises a first, a rear of one of the projections (19) encompassing hooks (38) and a second hook (39) encompassing a front of the refrigerated goods carrier (5; 6).

Description

The present invention relates to a refrigeration device, in particular a household refrigerating appliance, with built-in parts fixed in a storage chamber by means of a transport securing device.

Built-in parts, in particular shelves, are not fixed immovably in the storage chamber of a household refrigerator, so that users can place them at different heights. He can thus adapt the dimensions of the compartments into which the storage compartment is divided by the shelves to his individual needs. If such a refrigerator is used, the shelves are usually completely unsecured on carriers of the refrigeration unit body, or they are indeed secured by a positive connection, but this is to facilitate a user the Umplatzieren the shelves, by light train solvable. During transport of such a refrigeration device from the manufacturer to the user, the device may be tilted, or there may be shocks acting on it, which may cause the mounting parts to disengage from their intended position and damage themselves, other built-in parts or the inner container of the refrigerator. In order to prevent such transport damage, various devices have been proposed.

Such is the case, for example DE 20 2005 021 204 U1 a refrigeration device is known in which the rear edge of a shelf is inserted into a formed in the inner container of the refrigerator groove, wherein a spring of the shelf is locked in an undercut of the groove. Such a transport lock is economically feasible in an inner container formed of plastic, but hardly in an assembled from metal plates inner container of a refrigerator of the upper quality level. In addition, the protection by the spring obstructs a repositioning of the shelf during use, the stronger, the more effective the transport safety device.

In DE 10 2008 041 559 A1 has been proposed to fix a shelf, which is held in grooves of a side wall of the inner container, by a wedged between the shelf and the ceiling of the inner container cardboard containing the other components of the refrigerator. The effectiveness of this solution depends critically on the dimensional stability of the inner container and the carton. In addition, it is not very suitable for mounting parts that should be displaceable in the refrigerator on telescopic rails, because the telescopic rails each need their own transport safety, whether they are pre-assembled on the side walls of the inner container or stowed in the carton.

Out DE 10 2008 016 474 A1 Finally, the proposal comes as a transport lock to use a folded and slotted cardboard, which is attached to the front edges of shelves so that they engage in the slots, and is clamped between the front edges of the shelves and the door of the refrigerator. Although such a backup may also be useful for telescopic slide-movable shelves, such a carton must extend over the entire height of the storage chamber to support the shelves in the vertical direction to support the ceiling and floor, and the slots must be arranged in each case for the placement of the shelves matching height. The carton must therefore be made specifically for almost every model of refrigeration appliance, and its effectiveness also depends critically on its dimensional stability and that of the inner container.

There is therefore a need for a refrigeration device with a transport lock, which is modelnspezifisch usable. and their effectiveness is not affected by manufacturing tolerances.

The object is achieved by a refrigeration device, in particular a household refrigerating appliance, with a storage chamber, at least one refrigerated goods carrier supported on projections of side walls of the storage chamber and displaceable parallel to the side walls and a transport safety device comprising a first, a rear side of a hook engaging around the projections and a second , a front of the refrigerated goods carrier embracing hook comprises. The effectiveness of such a transport safety device does not depend on the dimensions of the storage chamber and the refrigerated goods carriers mounted therein, but only on the fact that the distance of the projection from the front side of the refrigerated goods carrier supported by it matches the dimensions of the transport safety device. This requirement is easily met in refrigerators with different housing dimensions.

According to a preferred embodiment, both hooks are adjustable relative to one another in the direction of displacement of the refrigerated goods carrier and can be fixed in different positions. Thus, the transport lock can be adapted to different distances between the projection and the front of the refrigerated goods carrier, which may be due to manufacturing tolerances, model differences of the storage chambers or the refrigerated goods, etc.

Preferably, the two hooks are formed as separate and interconnectable parts, for example as injection molded plastic parts. The bipartite facilitates the attachment of the transport lock, for example, first the first hook the back of the Projecting is placed encompassing and then the second hook is pushed from the front of the refrigerated goods carrier ago coming against the first, until it rests firmly on the front of the refrigerated goods carrier.

In order to guide the movement of the hooks against each other, preferably one of the two hooks has an elongate arm and the other has an arm-receiving channel.

In order to enable the hooks to be fixed to one another in the various positions, one of the two hooks preferably has a plurality of latching recesses and the other at least one latching lug, which in each case engages in different latching recesses in the different positions.

The locking recesses may expediently form a sawtooth contour, so that when moving the hooks against each other when attaching the transport lock the latch can successively jump from one locking recess to another and finally, when the second hook is applied to the front of the refrigerated goods, stuck in the last reached locking recess ,

In order to achieve an automatic locking of the locking lug in the locking recesses, the locking recesses and / or the locking lug should be elastically deflectable.

An operating section for manual elastic deflection of the latching recesses and / or the latching lug can be connected to the latching recesses or the latching lug, depending on which of the two is elastically deflectable, to give a user the opportunity to solve the latching again, without the transport lock to destroy.

In order to fix the refrigerated goods in the vertical direction, the first hook should extend to a bottom of the projection and have a projecting over an upper side of the refrigerated goods support leg.

Preferably, the leg touches the top of the refrigerated goods carrier to fix this clearance.

In order to facilitate a sliding of the first hook on the projection of the side wall and / or the play-free fixing of the refrigerated goods, the first hook is preferably limited elastically deformable.

The above-mentioned channel may expediently be formed in the leg of the first hook which extends over the upper side of the refrigerated goods carrier. If the above-mentioned operating section is present, it is easily accessible to a user by the placement of the channel at the top of the refrigerated goods carrier.

The transport protection formed by the two hooks is particularly advantageous applicable to a refrigerated goods, which is supported on the projections of the side walls via a telescopic extension.

Further features and advantages of the invention will become apparent from the following description of embodiments with reference to the accompanying figures. Show it:

1 shows a perspective view of a household refrigerator with a body 1 and a door 2 , In a storage room 3 inside the unit are a pull-out box 4 as well as pull-out shelves 5 . 6 shown. The shelves 5 . 6 each include a storage tray 7 made of safety glass and side edges of the plate 7 enclosing carrier profiles 8th of which only one is visible in the figure. The shelves 5 . 6 are slidably guided by telescopic extensions, which are in the in 1 shown inserted position of the shelves 5 . 6 in a lower region of the carrier profiles 8th . below the storage shelf 7 , are hidden. In the in the 1 empty upper area of the storage chamber 3 Additional shelves may be appropriate.

The shelves 5 . 6 differ in their depth. While the lower shelf 5 yourself like the pullout box 4 almost to a front of the body 1 extends, is the depth of the shelf 6 less to leave room for a door-mounted and closed door 2 in the storage room 3 immersed door racks 18 or possibly on this door rack 18 placed objects.

2 shows the shelf 6 and the telescopic extensions carrying it 9 in an exploded perspective view. As is the shelf 5 from the shelf 6 only differs by its depth, it is not specifically illustrated.

The metal or plastic, preferably aluminum, extruded carrier profiles 8th have below the storage shelf 7 one section each 10 of substantially rectangular or trapezoidal cross-section, with a horizontal upper flank 11 that one the plate 7 limited clamping groove, and an outer and a lower edge 12 . 13 , which are cut away on the major part of their length, around a recess 14 to form a telescopic extension 9 in the collapsed state can record and hide.

At the top of one over the storage tray 7 towering bridge of each beam profile 8th is a hollow bead 15 shaped, in the angled ends of a railing of the storage tray 7 forming right angle bent wire hangers 16 . 17 intervention. Due to the manufacturing process of the carrier profiles 8th runs a longitudinal channel within the bead 15 parallel to the flank 11 and the plate 7 , and it is sufficient to bend pieces of wire in two places at right angles to the bracket 16 . 17 to receive, which then only have to be inserted into the open ends of the longitudinal channels.

As in the presentation of 4 to recognize, is the here with 55 denoted longitudinal channel is not closed on its entire circumference, but it pulls a slot 56 at a location normally hidden from the gaze of a user on the girder profile 8th along. This slot 56 on the one hand simplifies the manufacture of the carrier profile, on the other hand it facilitates the fixation of the wire hanger 16 . 17 whether by creating the possibility, the bead 15 to compress so that the wire hangers 16 . 17 are firmly clamped therein or by allowing the insertion of adhesive, solder or the like.

The telescopic extension 9 is assembled in a conventional manner from two half-extracts, one of which in 3 is shown in an enlarged perspective view. The two half-extracts each comprise an inner rail 20 respectively. 22 and one the inner rail 20 . 22 with the formation of two longitudinal ball bearings encompassing outer rail 21 respectively. 23 , For fastening the inner rail 20 on a side wall of the storage chamber 3 serve two flat cylindrical inserts 19 which are inserted into not shown complementary recesses of the side wall and at its inner rail 20 facing facing end side not shown locking projections, which are adapted to be in openings of the rail 20 intervene and latch on. The rails 21 . 22 are firmly connected to each other, and to the outer rail 23 are two adapters 24 . 25 latched for mounting the carrier profile.

The front, to the door 2 adjacent adapters 24 is molded in one piece from plastic and has a cross-sectionally approximately L-shaped body with one on top of the outer rail 23 resting buffer 26 and one from the buffer 26 upwardly projecting latching projection 27 in the form of a letter T, from whose transom flexible tongues 28 projecting downwards. Outwardly facing outsides of the tongues 28 are curved convex.

The second, from the door 2 removed adapters 25 also has a main body of approximately L-shaped cross-section with one on the outer rail 23 resting buffer 26 , The buffer 26 is in the longitudinal direction of the telescopic extension 9 through two inclined surfaces 29 limited, each extending below the top of the outer rail 23 extend.

From the buffer of the adapter 25 is a Ω- or mushroom-shaped curved leaf spring 30 from whose two ends form-fitting in the body of the adapter 25 are embedded.

Both adapters 24 . 25 are mirror-symmetric with respect to a vertical median plane, so that in each case identical front or rear adapters 24 . 25 on the mirror-image opposite telescopic extensions 9 can be used.

4 shows in a perspective view from below the carrier profile 8th For mounting on the telescopic extension 9 of the 3 is provided. On a horizontal support surface 31 of the carrier profile 8th that the upper end of the recess 14 is adjacent to the front end of the recess 14 a window 32 cut, a slot 33 extends to the rear edge of the support surface 31 ,

If the shelf 6 on the on the walls of the corpus 1 mounted telescopic extensions 9 should be attached, it is initially with sloping trailing edge in the refrigerator 3 introduced, with the rear edges of the bearing surfaces 31 the two carrier profiles 8th on the outer rails 21 . 23 the two telescopic extensions 9 between the adapters 24 . 25 to come to rest. If the shelf 6 deeper into the refrigerator 3 is pushed into slide the trailing edges of the bearing surfaces 31 on the rails 21 . 23 along, finally reach the front inclined surfaces 29 the two rear adapters 25 and glide upwards. The leaf springs 30 back into the slots 33 one. If a leading edge 34 of the slot 33 against the leaf spring 30 bumps, can the shelf 6 be swung into the horizontal; the window 32 are placed so that they are in this position over the locking projections 27 the two front adapters 24 fall.

When the in 5 shown final position of the shelf 6 is reached, lies the bearing surface 31 on the buffers 26 the adapter 24 . 25 on, the bent tongues 28 the locking projection 27 are in contact with the edges of the window 32 slightly pressed against each other, and an obliquely upward and forward section 35 the leaf spring 30 is in contact with the leading edge 34 of the slot 33 slightly elastically deflected upwards. The clamping force of the spring is sufficient to the storage tray 7 even then keep safe in the horizontal when in a front edge area 36 , in front of the two front adapters 24 , so heavily loaded is that the common focus of the shelf 6 and the chilled goods in front of the adapters 24 lies.

If, however, the refrigerator with the in the configuration 5 held shelf 6 Transportation may be a shock or tilting of the device cause the shelf 6 from the adapters 24 . 25 solves. Further shocks can cause the unsaved shelf 6 slips back and forth and scratched the adjacent side walls, or that it crashes and the next lower shelf 5 damaged. To counteract this danger, the shelves 5 . 6 for transportation with the help of in the 6 to 9 shown transport lock 37 secured.

6 shows a transport lock 37 for attachment to a left front corner of a shelf 5 or 6 , A corresponding transport lock for the right front corner is formed in mirror image to that shown and not specifically shown.

The transport security 37 consists of two injection-molded plastic hooks 38 . 39 , The hook 38 includes a flat plate-shaped section 40 who, as stated by 7 is traceable, provided to enter from above into a gap between the carrier profile 8th and the carrier profile 8th opposite (in 7 not shown) side wall of the body 1 to be inserted from the top to a plate-shaped section 40 upwardly extending channel-shaped section 41 on the bead 15 of the carrier profile 8th to come to rest. Guided by the engagement of the bead 15 in the trough-shaped section 41 is the catch 38 in the longitudinal direction of the carrier profile 8th slid forward until the section 40 in the in 7 shown position on the insert 19 locked.

At one of the side wall of the carcass 1 opposite side of the channel-shaped portion 41 are two horizontal plates 42 . 43 molded, extending over the flank 11 of the carrier profile 8th and those on this flank 11 held storage tray 7 extend.

The plates 42 . 43 limit a channel 44 (please refer 8th ), in which an elongated thigh 45 of the hook 39 intervenes. At a bottom of the thigh 45 are regularly distributed locking recesses 46 formed in the form of a sawtooth profile, with in 6 . 7 invisible locking lugs 47 on an elastically deflectable arm 48 of the hook 38 interact. This fact is more evident in 8th , which is a side view of the transport lock 37 seen from inside the storehouse 3 here, shows. As can be clearly seen in this figure, have the locking recesses 46 and latching noses 47 each sloping flanks 49 . 50 on, which is a shift of the hook 39 inside the storage room 3 in with simultaneous elastic deflection of the arm 48 allow, whereas an outward movement of the hook 39 by flanks perpendicular to the direction of displacement 51 . 52 is blocked.

So after the first hook 38 on the shelf to be secured 5 or 6 placed and on the tray supporting this use 19 has been locked, it is sufficient, the second hook 39 from the front into the canal 44 push in until a bent head piece 53 of the hook 39 the wire hanger 16 embraces. Once this is done, the shelf is up 5 or 6 securely fixed both vertically and horizontally.

It is obvious that the hook 39 instead of the wire hanger 16 any other contour on the front edge of the shelf 5 . 6 could surround, in particular the front edge of the storage tray 7 ,

On the elastically deflectable arm 48 can an operating section 54 be provided, which, like in particular 9 becomes clear, in the lateral direction from the channel 33 protrudes. If the transport lock 37 is mounted, is the operating section 54 over the storage tray 7 and is good for a user to see and conveniently accessible. Even an inexperienced user is therefore quickly able to recognize without instruction that it is sufficient to the operating section 54 press down to latch the hook 39 solve this from the canal 44 pull out and finally the entire transport safety 37 to be able to remove.
