Abstract
Description
Technical field:
[0001] The invention relates to the flawless functioning of tilt-and-turn windows on niche / back wall panels of fitted kitchens. Background of the invention:
[0002] Previous methods for ensuring the proper functioning of tilt-and-turn windows on recessed linings where the material thickness between the side window reveal and the corner trim is less than 16 mm typically involve non-continuous or cut-out linings. This usually results in aesthetic compromises. Thinning the recessed linings is also complicated and time-consuming. Description of the invention
[0003] The invention comprises window corner trim pieces in the form of a straight and a 100° beveled shape. They are made of PETG (polyethylene glycol) material, as this material can withstand sunlight in the window area and retain its shape. The colors are matched to the niche linings and are, for example, white, black, gray, beige, brown, or anthracite. The inserts are fitted into the cutout of the niche lining with adhesive or silicone and fulfill the following functions: 1. Protective function: The shells protect the raw cutout against swelling damage in the back panel. 2. Installation flexibility: The choice of two shapes allows for flexibility in visual design, for example, if the window only has a single tilt-and-turn fitting. Measured on-site, the inserts can be adjusted in height and width to minimize loss of the attractive trim. Fig. The image shows a section where a worktop extends to the bottom of the window, and a trim piece has been notched out at the corner of the window on the left. The cut edge is unprotected and visually unappealing. Fig. shows the same situation as Fig. , but here the cutout is protected by the window corner trim and also visually enhanced in a more professional manner.
