EP0703415A1 - Front panel for panel-type radiator - Google Patents

Abstract

The front cladding (1) consists of a metal plate (2), whose four edges are bent through approximately 180 deg., whereby the inner located arms (4) run parallel to the metal plate and form a pocket (5). The four corners of the front cladding are rounded and bent over corresp. to the edges. In the corner areas of the metal plate two tongues (7) are formed by cut-outs, which are so formed that after the bending over through approximately 180 deg. their flanks (87) locate tightly against each other and tightly against the ends (9) of the bent-over edges (3).

Description

The invention relates to a front panel for panel radiators, consisting of a metal plate with edges bent by approximately 180 ° and rounded corners.

Metal panels are used for the front cladding of panel radiators, which are attached to the radiator by gluing, hanging or the like and cover the front side thereof. For good coverage and aesthetically pleasing cladding, it is known to bend the edges of the panel and round off the corners of the front cladding. In large production series, this is done by deep drawing the metal plates. However, this method is uneconomical in the case of small quantities, since a separate tool must be procured for each size of plate to be manufactured. For this reason, rectangular sheets punched out in small series are used, the edges of which are bent over, with spaces between the angled edges which are covered by attached plastic caps. Such plastic caps affect the appearance of the front panel and require additional manufacturing steps and storage.

In contrast, the invention has for its object a front panel corresponding to the preamble of the protection claim to be designed in such a way that an economical production of an aesthetically pleasing front panel is possible even with small quantities.

This object is achieved by the features specified in the characterizing part of the protection claim.

The front cladding described in the invention can be produced by punching steel plates and then bending the edges and corners. The corners consist of at least two tongues which are shaped by cutouts in such a way that a rounding in the corner region of the plate occurs after the bending process. The flanks of the tongues are advantageously close together and against the ends of the bent edges, as a result of which the front cladding is given a flat and aesthetically pleasing surface. The bending of the tongues into rounded corners is so precise that the required tolerances can be met without expensive post-processing. A production of the front cover in the above-mentioned manner is economical because of the use of inexpensive tools and a possible avoidance of expensive storage.

1 consists of a metal plate 2, the four edges 3 of which are bent by approximately 180 ° (cf. FIG. 2), the inner legs 4 running parallel to the metal plate 2 and forming a pocket 5. The shape of the bend, such as the bending radius or the width of the legs 5, can take place depending on design considerations or the type and design of the fastening means with which the covering is attached to the front of a flat radiator.

The four corners of the front panel 1 are rounded and bent over according to the edges 3. To create such a simple bend, as shown in FIGS. 4 and 5, two tongues 7 are formed in the corner area of the metal plate 2 by cutouts 6, which are designed such that their flanks 8 are close to one another after the bend by about 180 ° or lie close to the ends 9 of the bent edges 3 (see FIG. 3). The outline of the tongues 7 can with With the help of CAD programs can be determined or can be found by cutting and processing a pattern. After the tongues 7 have been bent over, the corner regions have approximately the same cross-sectional profile as the edges 3. The edges 3 and tongues 7 are bent over using suitable bending tools.

The finished front panel 1 is painted in the usual way, the paint in the corner area covering the narrow joints between the tongues 7 or between the joints 7 and the corners 9 of the edges 3 and forming a completely flat paint surface.

Depending on the shape of the rounding, three or more tongues can also be provided instead of two tongues 7. If required, the front cladding can also be attached alone or additionally to the surface of a flat radiator facing a wall. This applies in particular to flat radiators that are installed in front of a glass wall. Likewise, the attachment to radiators and convectors u. Like possible.
