FERNBERG FASTENER 2 Sheets-Sheet 2 'IIIfl/Illl 4 Ii: V TO R EH1 C Di RbhR r Eh BERG ATTOENEY 3,003,215 FASTENER Eric Birger Fernberg, Northwood, England, assignor to RT. Products Limited, London, England, a British company Filed Sept. 16, 1957, 'Ser. No. 684,081 Claims priority, application Great Britain Sept. '17, 1956 1 Claim. (Cl. 24-259) The present invention relates to an improved fastener.
It is common practice in the car manufacturing trade at the present time to cover an edge of a metal panel forming part of a car body with rubber strip of channel section. The strip is held over the edge with U-shaped spring clips which are formed with internal rearwardly directed prongs engaging the metal edge and with external prongs or lugs engaging the rubber strip. The rubber strip serves to hide the edge and may also serve as a draught-excluder if used on a door panel.
The member to be covered may consist of a single metal edge, or of two or three such edges welded together, and it has been found in practice that where two or three edges have to be covered the edges may lie flush with one another at some positions along the length of the edges, but lie out of register at other positions.
It is an object of this invention to provide clips of single size and shape which will accommodate this outof-register feature of such plates and which can also be engaged on panels of a wide variety of thickness.
According to the invention a U-shaped spring clip is provided in its limbs with two pairs of inwardly and rearwardly directed prongs, the one pair being longer, more resilient and more nearly bridging the gap between the limbs of the U than the other pair.
Preferred forms of the invention will now be described with reference to the accompanying diagrammatic drawings, in which:
FIGURES l, 2, 3 and 4 are respectively a plan, front elevation, rear elevation and side elevation of a fastener,
FIGURE 5 is a front elevation of two metal edges, welded together, over which the clip of FIGURES 1 to 4 is to be engaged,
FIGURE 6 is a side elevation of the same fastener engaged over a metal edge of double thickness,
FIGURE 7 is a side elevation of the same fastener engaged over a metal edge of triple thickness, and showing also a draught-excluding rubber strip engaged by the clip so as to cover the edge, and
FIGURES 8 and 9 show, respectively, the same clip engaged over a single edge and over a triple edge in which one panel is out of register with the other two.
The clip indicated generally at 10 in the figures is formed from a single rectangular strip of metal which, after it has been fashioned to its final shape, is rendered resilient and rustproof in any suitable manner.
The body of the clip is formed with a bridge or web 11 and two limbs 12 and 13. Out of the web 11 are sheared a pair of pointed upstanding claws 14 and 15 designed in use to engage a rubber strip to be described later. The claws lie in the plane of the fiat limb 13.
The limb 12 is bent as shown so as to have, at its foot, a lead-in portion 16 and is also formed with two pairs of prongs 17, 18 and 19, 20.
The prongs 17 and 18 are longer and more resilient than the other pair and are formed, with respect to the rectangular blank, in line with the claws 15 and 14. A portion of the metal between the claw 15 and prong 17 is removed so that the claw and prong may be sharply pointed. The claw 14 and prong 18 are similarly formed (see FIGURE 1).
The prongs 19 and 20 are relatively short and are formed by cutting away areas of metal 21 and 22 around nited States Patent the tips of these prongs and by suitably shearing the metal.
The longer prongs 17 and 18 are bent inwardly and to wards the web 11 of the clip (see FIGURE 4) so as nearly to bridge the gap between the two limbs 12 and 13. The prongs 19 and 20 are also bent inwardly and rearwardly towards the web 11 but, being considerably shorter than the prongs 17 and 18, have their free ends lying further from the flat limb 13, and further from the web 11, than the free ends of the longer prongs 17 and 18.
At 23 and 24 in FIGURES 5 and 6 are shown portions of two metal panels welded together so as to present a pair of edges 25 and 26. Ideally the extreme edges would be flush one with the other but in practice it is found that quite wide departures from this ideal have to be accommodated. However, the clip described will accommodate both this lack of register of the metal edges and the wide variation of thickness occurring when one, two or three such edges have to be covered.
As shown in FIGURES 5 and 6, the clip 10 is engaged over a panel of double thickness. As shown in FIGURE 7 the same clip is engaged over a treble thickness and as shown in FIGURE 8 engaged over a single thickness.
In the case of FIGURES 6 and 8, it is the longer prong 18 only which engages the single or double thickness panels. In the case of FIGURE 7, both the longer and shorter prongs engage a treble thickness panel.
As shown in FIGURE 9, the outer panel 25A of a treble thickness panel has its edge seriously out of register with the other two panels 24 and 26. In this casethe shorter prongs, such as 20, engage the outer panel and the longer prongs, such as 18, may either stand clear of the centre panel 24 or may engage it lightly.
Where both pairs of prongs engage the metal, the
trated by way of example in FIGURES 7 and 9, where in each case there is shown a draught-excluding rubber weather-strip having one portion 27 of U-section and an-- other portion 28 of cylindrical shape. Around the U-- portion is secured a stiff flexible finishing strip 29' also of U-section.
The composite strip is held on to the triple edge with the aid of several clips, each clip having its claws 14 and 15 digging into the rubber U-portion 27 and one edge of the finishing strip engaged under the lead-in 16 of each clip. The cylindrical portion of the rubber strip serves as a draught excluder for an automobile door. The claws may extend into the finishing strip 29, but normally should not pass right through it.
What I claim is:
