Refrigerated furniture with a housing made of rigid plastic foam that is at least partially clad on both sides

The innovation relates to a refrigeration unit with at least one part Housing made of rigid plastic foam, clad on both sides, whose cladding is composed of several individual parts, which are attached to the joints by inserting the hand strip of one part is joined together in a groove provided on the edge of the other part and inserted between the cladding Rigid plastic foam are held together.

•1 ··· ·

In the known refrigeration units of the type mentioned, it is common to have the parts of the paneling at their joints in the manner of a Put together tongue and groove connection. However, it is necessary to remove the joints after the Cover parts of the cladding facing the rigid foam with adhesive tape or seal with putty. This prevents the parts from becoming detached from one another before they pass through the cured rigid plastic foam are firmly connected to each other and that not yet hardened plastic emerges from the groove on the surface of the parts.

To improve the sealing effect in the groove, the edge strip of one part, which serves as a tongue, has been provided with grooves or notches in which the not yet hardened plastic rigid foam that has penetrated the groove can harden and prevent it from escaping to the surface of the parts will. However, sealing and connecting the joints requires a relatively large amount of labor and sealing material.

The innovation is based on the task of eliminating the disadvantages that occur in the known joints between the joints. This is achieved according to the innovation in that at least one side wall of the groove in the vicinity of the opening one after has internally projecting approach, against which the other part inserted into the groove with a projection of its edge strip supports.

With the design of the butt joint according to the innovation, a tight and non-positive connection is easily established the cladding parts made at their joints, so that the additional means previously used for connecting and sealing the joint become superfluous and the Labor for the production of the refrigerated cabinet is significantly reduced.

An advantageous development of the subject of the innovation results from the fact that the approach by a along the groove opening extending strip-like thickening of one of the two side walls delimiting the groove is formed.

In the drawing, three embodiments of the subject of the innovation are shown. Show it:

Pig. 1 a joint of two cladding parts plugged together, one with rigid plastic foam heat-insulated housing in section,

Pig. 2 shows a joint of two differently designed cladding parts, as a second exemplary embodiment, also in the cut and

Pig. 3 shows a third exemplary embodiment, also in section.

The one in the Pig. 1 edge section shown in the cutout Door opening of a refrigerated cabinet thermally insulated with rigid plastic foam TO is provided with an outer cladding 11 and with a

Inner lining 12 provided, which at their touching one another Edges are connected by a butt joint. For this purpose, the outer cladding 11 is at its edge zone a groove 13 is provided, which is delimited on its flanks by side walls H and 15. The side wall 15 faces the opening the groove 13 has an inwardly projecting shoulder 16, which in the illustrated embodiment as a along the groove opening extending strip-like thickening is formed. The inner lining 12 is inserted into the groove 13 on its side inserted edge strips are equipped with a bead 17 running parallel to the outer edge of their edge strip, which with its protruding curvature against the side wall 15 of the groove 13 equipped with the projection 16.

In the embodiment according to Pig. 2 is the joint by crimping the inner lining 12 and by arranging the side walls 14 and 15 delimiting the groove 13 accordingly executed flush. In this case, a bead 17 'with a trapezoidal cross-section is also in the edge strip of the inner lining 12 intended.

In the exemplary embodiment according to FIG. 3, instead of the bead 17 or 17 'on the edge strip of the inner lining 12, there are two parallel to each other running strip-like thickenings 18 provided, which from the surface of the edge strip against the with the projection 16 equipped, the groove 13 delimiting the side wall 15 protrude.

• C ·

Before the wall of the refrigerated cabinet is filled with foam, the parts of the cladding are simply nested with the edge strips firmly joined together. The side walls H and 15 delimiting the groove 13 are initially spread apart resiliently, until the projection 16 engages behind the bead 17 or 17 * or the strip-like thickening 18 in the direction of insertion and thereby frictionally connects both parts. Through the bead 17 or 17 'or the thickenings 18 in or on the edge strip of the inner lining 12 are in the groove formed several relaxation rooms, in which the following Foaming penetrating reaction mixture to form the rigid plastic foam hardens before it hardens at the joint to the outside on the surface of the paneling parts can. In this way, the usual measures for the known connections of the paneling are fixed There is no need to connect and seal the joints.
