Abstract
859,862. Refrigerators. GOODRICH CO., B. F. Feb. 19, 1959 [Feb. 20, 1958], No. 5782/59. Class 29 [Also in Groups XXV, XXVI and XXXV] The steel door of a cabinet, e.g. a refrigerator, is both held shut and sealed by a hollow gasket containing a flexible magnet (see Group XXXV). The magnet comprises magnetized particles of ferrite in a resin binder arranged in blocks 23 on an adhesive flexible tape 13, and is inserted in a channel 40 in the gasket 38 which is of elastomeric material and has an attachment flange 39. The magnet strip is thinner than the height of the channel so that, when attached to the bottom 41 by staples or an adhesive, a space remains to allow for compression of the gasket when in use. The complete door fastener is made by forming a rectangle of four gasket strips, the corners being mitred and heat sealed. To facilitate this the magnets stop short of the corners and the channel 40 is filled with a packing e.g. of glass wool.
