Resilient wire clips with multiple pair sections and crossed ends for attaching a tubular braided gasket to an oven door having groups of clip receiving apertures at variable intervals

摘要

An oven door seal comprises a braided tubular gasket of wire and a mineral fiber, such as glass fiber, a ceramic or quartz or mixtures thereof. The gasket has the characteristic of a braided structure of radial expansion upon axial compression and radial contraction upon axial extension. Clips of resilient wire are prebent in a common plane so as to have an apexed head formed near the mid point of the wire intermediate parallel sections and crossing end sections are disclosed. The clips are inserted into the gasket with the crossing ends spanning one or more filaments in the lattice structure of the braided tubular gasket and the crossing ends pass through the wall structure and are deflected generally parallel to the wall as the clip wire sections at the apex flex together. The apertures are formed in the oven door perimeter at different spacings depending upon the gasket diameter desired along the edge having a particular spacing and the clip inserted at equal spacings in an oven door. The installed gasket may have a smaller diameter along the hinge side of the door and a larger diameter along the side most remote from the door on account of the variable spacing of the apertures.
