Abstract

A refrigeration device comprises a built-in unit, especially a pull-out drawer (4), which is guided on telescopic pull-out elements (5) so that it can be pulled out from an interior space (3). Every telescopic pull-out element (5) comprises at least one rail which is stationary (9) in the interior space (3), a rail (12) which can be displaced together with the built-in unit (4) in a depth direction of the interior space (3) and a cover part (13) extending along the mobile rail (12). At least one first cover part (13) and the built-in unit (4) have contours (16, 28) which are complementary to each other and engage with each other in a form-locking connection in a width direction of the interior space (3).

Description

Refrigeration unit with telescopic extension

The present invention relates to a refrigeration appliance, in particular a household refrigeration appliance, with a built-in retractable on telescopic extensions of an interior fixture, each telescopic extension at least one stationary in the interior and a movable with the fixture in the depth direction of the interior rail and extending along the movable rail Cover part includes.

Such a refrigeration device is known from DE 10 2006 061 096 A1. A telescopic extension of this refrigerator has a plurality of mutually movable rails, two latched on a movable rail adapter for anchoring a drawer to the movable rail and a movable rail with the movable cover, which conceals the rails of the telescopic extension to a large extent. The production of such a telescopic extension is expensive, because the two adapters and the cover must each be individually mounted on the movable rail, and large area

Cutouts of the cover must be exactly matched to the adapter and the movable rail in their dimensions and their position so that the adapter latched on the rail fill the sections exactly and no unsightly and difficult to keep clean joints between the adapters and the cover.

An object of the invention is to provide a refrigeration device with a mounted on telescopic extensions movably mounted part in which the rails of the telescopic extensions are hidden by a cover and which is easy and efficient to install.

This object is achieved by providing in a refrigeration device in which a built-in part is guided on telescopic extensions pulled out of an interior and each telescopic extension at least one fixed in the interior and one with the mounting part in the depth direction of the interior movable rail and extending along the movable rail Cover part comprises, on at least a first of the cover and on the fitting complementary to each other, formed in the width direction of the interior of a form-fitting interlocking contours. That's how it reduces the number of parts to be mounted on the movable rail of each telescopic extension to one, and eliminates the problem of dimensional tolerances between rail, adapters and cover.

Preferably, the insert is slidably mounted on a second cover part of another of the telescopic extensions in the width direction. Thus, tolerances of the width between the interior and the mounting part can be intercepted in a simple manner.

If the positive engagement between the complementary contours of the mounting part and the cover leaves a residual freedom of movement of the first cover and the fixture against each other in the width direction, this should be smaller than a maximum overlap width of the fixture with the second cover to be sure that the fixture is not of can slip off the second cover.

An end wall of the cover member may cover a pull-out front end of the rails. Thus, when the drawer box normally carried by the telescoping extensions is removed, a user may be prevented from soiling himself or his clothing at the exposed ends of the telescopic drawer or from injuring themselves on sharp edges of their rails.

A front wall of the mounting part can in turn cover the end wall of the cover, so that it is completely hidden when installed mounting part.

In order to secure the mounting part against being pulled out beyond a stop of the rails, the mounting part preferably has a projection which extends transversely to the pull-out direction and engages behind an edge of the cover part.

Preferably, the mounting part has a forward sloping wall, which lies opposite the end wall of the cover. This sloping wall creates the possibility that when inserting the insert the telescopic extensions reach a stop, the mounting part along the sloping wall can slide slightly upwards. Thus, kinetic energy of the insert - which can be considerable if it is in the built-in z. B. is a fully loaded drawer - be dissipated without exposing the insert a sudden load that could lead to cracking in the material of the insert in case of repetition.

For the same purpose may be provided on the front wall of the cover a forward sloping outside.

Since the sloping surface of the fixture or the cover allows the dissipation of kinetic energy, not special as adapter DE 10 2006 061 096 A1 between fixture and rail are required to absorb shock, but the cover can do this function, without long-term damage to take.

In order to favor the sliding of the mounting part and the cover part against each other, both the sloping wall of the mounting part and the sloping outside of the end wall of the cover part can be provided, and both extend substantially parallel to each other.

On an inner side facing the rails, the end wall preferably has a projection which engages in a longitudinal channel delimited by the rails and thus secures the positioning of the cover part on the rails.

A projection extending in the withdrawal direction of the fitting, which engages under the end wall, secures the fitting against accidental lifting of its front portion and thus ultimately against accidental release of the telescopic extensions. In addition, the projection limits the path by which the fixture can slide up along the sloping wall when it is abruptly decelerated in its retracted stop position.

At least one of the telescopic extensions and the built-in part preferably have contours which engage in a form-fitting manner in the width direction of the interior.

By these contours limit the freedom of movement of the fixture in the width direction, they can prevent slippage of the fixture even if one of the telescopic extensions does not have the contours and the fixture thus slidably rests in the width direction on this telescopic extension. The absence of the interlocking contours on an extension simplifies installation of the fixture, and it allows the compensation of width tolerances of the interior and the fixture.

An edge of the cover, which extends below the concealed rails of the cover, can prevent dirt particles from the telescopic extension are distributed in the interior.

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

Fig. 1 is a perspective schematic view of a refrigerator according to the present invention;

Fig. 2 is a perspective view of a complete telescopic extension;

3 shows a perspective view of a cover part of the telescopic extension;

Fig. 5 is a perspective view of a rear corner of the pullout box.

Fig. 1 shows a perspective view of a refrigerator with a body 1 and a door 2, which enclose a thermally insulated interior 3. In the interior 3 a plurality of pull-out boxes 4 are housed. At one of these pull-out boxes 4, which is shown in the pulled-out position, a telescopic extension 5 at the bottom of a right side wall 7 and a step 6 can be seen in a left side wall 7, which conceals a second telescopic extension. A front side 8 of the pull-out boxes extends over the entire width of the interior 3, so that in the inserted position of the

Pull-out boxes 4 the telescopic extensions 5 completely hidden behind the front pages 8 and are not visible. Of the two telescopic extensions 5, which carry each drawer 4, one is shown in Fig. 2 in a perspective view. At one in Fig. 2 facing the viewer open back of the telescopic extension 5 ends of two pairs of mutually in a conventional manner by means of inserted balls telescopically movable rails 9, 10 and 11, 12 to see, of which a stationary rail 9 is provided for attachment to a side wall of the body 1, the rail 12 is fixedly connected to a cover 13 and the mutually firmly connected rails 10, 11 are each movable at half the speed of the rail 10.

The molded plastic cover member 13 has substantially the shape of a C-profile, between the horizontal legs 14, 15, the rails 9, 10, 1 1, 12 are added. In the upper horizontal leg 14 is located near the rear end of a detent opening 16th

A shown in Fig. 2 separated from the cover 13 locking clip 17 is provided to pass through an opening 18 in a leg 14, 15 connecting vertical

Side wall 19 of the cover 13 through into T-shaped openings 30 of the movable

Rail 12 intervene. As the view of FIG. 3 shows, carries the locking clip 17 on its side facing the cover 13 side two T-shaped projections 31 which in the

Openings 30 are insertable. By displacing the latching clip 17 engaging in the apertures 30 in the longitudinal direction of the cover member 30, upwardly and downwardly projecting arms of the projections 31 engage behind the edges of the apertures 30, thereby locking the cover member 13 to the rail 12.

At a visible in Fig. 3, the telescopic rails facing the inside of the side wall 19 of the cover 13, a flat annular projection 20 is formed, which is provided to engage in a complementary opening of the rail 12 positively. Since the rail 12 rests directly on the inside of the side wall 19, 20 considerable forces in the withdrawal direction between the can

Cover 13 and the rail 12 are transmitted without overloading the material of the cover 13.

The front end of the cover member 13 is formed by a hollow prism 21. Both the prism 21 itself and its rails 9 to 12 facing the inner wall 22 as its forward sloping outer wall 23 can be considered as an end wall, which closes the cover 13 to the front and completely hides the rails 9 to 12 housed therein.

A projecting from the inner wall 22 in the space between the horizontal legs 14, 15 pin 24 engages in the assembled telescopic extension 5 in a longitudinal channel 25 formed between the rails 1 1, 12 a. By the top of the

Rail 12 in a space between the pin 24 and the side wall 19 of the

Cover engages, the cover 13 is held immovably in its front region in the width direction of the body 1. The cover member 13 is quickly and easily assembled by sliding it on the rails 9 to 12 from the front until the rail 12 engages between the pins 24 and the side wall 19 and the ring 20 is inserted into a complementary opening of the rail 12. The still pivotable in this state rear end of the cover 13 is brought into contact with the rail 12. By inserting the locking clip 17 into the openings 18 of the cover 13 and 30 of the rail 12, the cover 13 is completely fixed to the rails.

As can be seen in the view of FIG. 4, when the pull-out box 4 is mounted on the telescopic extension 5 (viewed from the right), a lower side of the step 6 rests on the leg 14 of the cover 13, and the step 6 behind Front extending, sloping wall 26 rests on the outer wall 23 of the prism 21. A protruding from the sloping wall 26 horizontal plate 27 engages under a front tip of the prism 21. The projection 24 is hidden in this view of the rail 10.

If, when closing the pull-out box 4, the rails abruptly abut a stop, and the pull-out box 4 is driven further by its inertia, the sloping walls 23, 26 can slip against each other, causing the pull-out box 4 to be raised and gradually slowed down. The freedom of movement of the pull-out box is limited by the contact of the horizontal plate 27 with the underside of the prism 21st

Fig. 5 shows a perspective view of the right rear corner of the pull-out box 4. From the horizontal step 6 of the pull-out box stands near its rear end a finger 28 vertically downwards, which engages in the latching opening 16 of the cover 13. The engagement of the finger 28 is so far playful in the depth direction of the body that a contact of the finger 28 is excluded with the front and rear edge of the detent opening. An overload of the finger 28 in an abrupt reaching a stop is so excluded. The finger 28 fixes the position of the pull-out box 4 in the width direction and prevents the step 6 from slipping off the pull-out 5. The widths of the interior 3 and the pull-out box 4 are coordinated so that the not shown in FIG., Opposite left stage 6 of the pullout box rests securely on the left pullout 5. This left stage 6 has no finger 28, so that width tolerances of the interior 3 and drawer 4 can be compensated by differently wide overlap of the left stage 6 with the horizontal leg 14 of the carrying extract 5.

At the rear end of the step 6, a vertical plate 29 is connected at the top and side in one piece with the drawer 4 and engages behind the rear end of the cover 13 and the rail 12. It limits the range of motion of the drawer 4 against the cover 13 during withdrawal and ensures in that when the pull-out box is pulled up, the rail 12 is entrained. The plate 29 is provided at both rear corners of the pull-out box 4.

In order to assemble the pull-out box 4, it is sufficient to initially place it on the two telescopic extensions 5 in such a way that the vertical plates 29 rest on the upper horizontal legs 14 of the two cover parts 13 at its two rear corners. When the drawer 4 is then inserted into the interior 3, and the platelets 29 reach the rear end of the cover 13, the steps 6 of the drawer 4 come to lie on the cover 13, the horizontal plates 27 reach under the top of the prisms 21, and the drawer is locked.
