1,003,334. Stud and socket fastenings. F. T. PRODUCTS Ltd. Jan. 21, 1964 [Feb. 1, 1963], No. 4319/63. [Addition to 890,972] Heading E2B. A fastener 10, Fig. 6, for securing two members 38, 39 together, comprises a stud 12, and a retainer 11, in which the stud 12, Fig. 4, is in the form of a single strip of material which has been rendered resilient in the shape of an open loop, the limbs 28, 29 of the loop have inwardly directed feet 30, 31 and one of the limbs has an outwardly directed elbow for snap engagement in an aperture 41 in the member 38, in which the retainer 11, Fig. 3, has a substantially flat body 13 formed with a pair of cuts, the material between which is pressed out of the general plane of the body to form a shelf 20 under which the felt 30, 31 of the stud may be slidably engaged by opening the limbs and allowing the feet to spring back under the shelf, and in which each cut in the body 13 is non-rectilinear or both cuts are rectilinear and inclined to one another. In the embodiment shown both limbs of the stud 12 have outwardly directed elbows and each has a cut out 34, 35 the bottom corner of which is folded out to form a prong 36, 37. The retainer 11 is of deformable material and has legs 14, 15 at right angles to the plane of the body 13. To connect together the members 38, 39 which are a tube 38 with an aperture 41, and a panel with an aperture 40 respectively, the stud is first attached to the retainer by opening the limbs 28, 29 and allowing the feet 30, 31 to slide beneath the shelf 20. The stud and retainer are then inserted into the aperture 40, and the lower portions of the legs 14, 15 are bent as shown in Fig. 6, so that the body 13 of the retainer is clenched against the rim of the aperture. The tube 38 is then brought up against the panel 39 so that the outwardly elbowed limbs snap engage in the aperture 41. In modifications described in the Provisional Specification the cuts in the retainer are parallel straight lines and the ends of the limbs are bent outwardly to form lugs, inwardly directed feet being sheared from the limbs and bent into position. Alternatively the ends of the limbs are bent inwardly to provide feet and outwardly directed lugs are formed by making triangular cuts in the limbs and bending up the cut out material. |
