1319113 Stud and socket fastenings WARREN FASTENER CORP 4 Nov 1970 [5 Nov 1969] 52375/70 Heading E2B An adaptor 40 for use in securing a channel-shaped trim strip 20 to two headed studs 38 projecting from a support 36 has end portions 74, 76 shaped to engage inturned flanges 78, 80 of the strip over a range of angles of inclination of the adaptor to the lengthwise direction of the strip so that like adaptors car grip a strip of varying width at intervals along its length by being inclined thereto at different angles, the adaptor being provided with two key-hole apertures 48, 50, each aperture having a slot 56, 70 which provides a seat 58, 71 to slide under the head of a respective one of the studs, the two seats being elongated in a common direction to permit widthwise adjustment of the strip after assembly, the slot which provides the seat of a first one of the apertures 56 leading to an opening 52 at one end of the slot through which the head of one of the studs can be received and the slot of the other aperture being connected to such an opening 66 by a transverse passage 68 which leads from the opening to the seat and permits the adaptor after the seat of the first adaptor has been assembled on said one of the pair of studs to be placed over the head of the other stud which passes through the opening of the other aperture and is caused to slide under the head of that stud by rotation about the stud in the first aperture to bring the seat of the first aperture under its stud head. As shown, the key-hole aperture 48, which is arranged uppermost when the adaptor is used, is disposed in a tongue 64 which is separated from the remainder of a body portion of the adaptor by a U-shaped slot 62; the provision of the tongue allows upward movement of the body portion after the first stud is seated in the aperture 48 to be lifted to engage the second stud. The upper end portion 76 of the adaptor has a pair of fins 88 which separate the strip from the panel; the lower end portion also has a pair of fins 84 and also two fingers 82. The fins are disposed underneath the flange 78 and the fingers are received in the flange. The fingers hold flange 78 in place, the other flange of the trim strip being snapped beneath a downwardly facing shoulder 86 of the body portion. The fingers compensate for tolerance variations in the strip width. Opposed edges 90, 92 of the adaptor are truncated to allow the adaptor to grip different widths of trim strip. |
