1,012,280. Spring clips. DRAFTEX Ltd. Nov. 28, 1963 [March 26, 1963], No. 11967/63. Heading E2B. A clip is formed by slitting a narrow strip-like blank of material transversely at spaced positions throughout its length the slits extending to positions situated at a short distance from the opposite longitudinal edges of the blank and slitting the blank longitudinally at spaced positions throughout its length to leave a series of transverse parts 4 connected by longitudinal edge portions 5 and between such parts a series of oppositely positioned inwardly directed tongues 6, the transverse parts being bent into substantially inverted U-shape and the tongues being bent outwardly and downwardly through an angle of substantially 270 degrees from their original positions into a position in which they form spaced downwardly directed limbs. The edge portions 5 can either be at right angles to the downwardly directed limbs 6 or they can be directed upwardly towards the parts 4. The longitudinal edges of the portions 5 can either be straight or they can be sinuous or undulating or the edge portions can be shaped to provide a series of spaced sharp points. The clip is used for securing sealing or trimming strip to a supporting flange the strip being folded round the clip and trapped between the edge portions 5 and the flange. In a modification the end portions of the limbs 6 can be bent inwardly to face each other. With such a construction the trimming strip is trapped between the inwardly bent portions of the limbs 6 and the flange instead of being trapped between the edge portions 5 and the flange. |
