8 Claims. (Cl. 24-20515) The present invention is directed to a slider, and more particularly to a slider for use with slide fasteners, which slider may be assembled onto'the slide fastener tapes after the same have been sewn into position.

It has long proved desirable to provide a slider which can be assembled onto the elements of sewn tapes. For

' example, in concealed slide fasteners where it is desirable to stitch the tapes to the underlying cloth articles by a line of stitching which is asclose as possible to the elements of the slide fastener, the presence of the slider on the tapes during the sewing operation interferes with the positioning of the line of stitching closely adjacent to the slide fastener elements.

This invention has as an object the provision of a multi-component slider, whose components may be rapidly and easily assembled into position upon elements of a slide fastener.

This invention has as another object the provision of a slider which may be readily mounted onto and released from slide fastener element carrying tapes.

Other objects will appear hereinafter.

For the purpose of illustrating the invention there is shown in the drawings forms which are presently pre ferred; it being understood, however, that this invention is not limited to the precise arrangements and instrumentalities shown.

Referring to the drawings, wherein like reference characters refer to like parts;

Figure l is a plan view looking downward onto the assembled slider.

Figure 2 is a plan view of the other side of the slider from that shown in Figure 1.

Figure 3 is a section taken on line 3-3 of Figure 1.

Figure 4 is an exploded view of the slider of Figure 1 revealing the components thereof prior to assembly.

Figure 5 is a plan view of the slider of Figure 1 revealing the pivotation of the wings of the slider prior to the insertion of the locking clip.

Figure 6 is a perspective view of another embodimentof the slider of the present invention.

Figure 7 is an exploded view of the components of the slidei of Figure 6. 1

Figure 8 is a perspective view of yet another embodiment of the slider of'the present invention.

Figure 9 is an exploded view of the components of the slider embodiment of Figure 8. t

Referring initially to'Figures 1 through 5 inclusive,

there is shown therein a presently preferred embodiment 12b are beveled to form a scarf half joint. This permits the

back plate halves

12a and 12b to be pivoted about the pin 18 which passes through the opening 20 in ear 14 and the opening 22 in car 16 (see Figure 4). The size of the

openings

20 and 22 in relation to the pin 18 is such that the fit is a relatively loose one enabling the

back plate halves

12a and 12b to readily pivot about the pin 18.

The

back plate halves

12a and 12b are formed in the shape of wings and are provided with

respective side arms

24 and 26, which are contoured so as to besubstantial juxtaposed images of each other.

The separator or wedge or diamond 28 is carried on the inside face of the back plate 12. The separator 28 is provided with a blind hole 30 (see Figure 4) into which the pin 18 maybe drive fit. In the assembled disposition of the slider 10 shown in Figures 1, 2, and 3, the separator 28, which is a symmetrical body is positioned along the center line of the slider 10 running from the uppermost portion thereof to the bottomrnost portion thereof. Thus, the

abutting edges

32 and 34 of respective

back plate halves

12a and 12b come together on the center line of the back plate 12 and bisect the apex 36 which is defined by the

separator arms

38 and 40 which converge inwardly from the uppermost portion of the slider 10.

The separator 28 is provided with an upwardly projecting lug 42 which has an aperture 44 for receiving the pull tab shown in phantom as 46.

The

back plate halves

12a and 12b are secured together by the locking clip 48 which is received within the

mating grooves

50 and 52 of

back plate halves

12a and 12b.

Such grooves

50 and 52 extend across the back, side, and across an appreciable portion of the front of their respective

back plate halves

12a and 12b. The locking clip 48 should be formed of resilient spring metal so that it will slip into position in the

grooves

50 and 52 in the manner shown in Figures 1 and 2 whereby the back plate halves 12a and 1212 will be retained asscmbled. The locking clip 48 may be pried loose from the mating groove formed by the

grooves

50 and 52 enabling the back plate halves 12a and l2b to be separated when the same is desired.

The slider 10 may be furnished to the ultimate user in the manner shown in Figure 5, namely as the pivotable

back plate halves

12a and 12b, separator 28, and pin 18 assembly, and the locking clip 48. The assembly'may be mounted upon slide fastener elements carried by slide fastener tapes which have been sewn into position.

After the assembly has been so-mounted, the locking clip 48 may be inserted into the

grooves

50 and 52 to produce the assembled slider 10 shown in Figures 1, 2, and 3. This permits the slider 10 to be mounted upon slide fastenerelement carrying tapes having both a top stop and a bottom stop or bottom clip. 1

Referring now to Figures 6 and 7 there is shown therein the modified slider embodiment designated 10'. Slider 10' comprises the mating back plate halves 12m and 12bb.

The back plate halves Hat: and 12bb differ from the

back plate halves

12a and 12b of slider 10 in that in place of the

cars

14 and 16 thereis provided the respective

joint elements

54 and 56 on back plate halve Hat: and the respective

joint elements

58 and 60 on back plate halve 1212b. The joint'elements54 and 56 of back plate halve 1211a and the

joint elements

58 and 60 of back plate halve 1212b comprise laterally projecting members disposed in the plane of the back plate halves 12m: and 12bb. The joint element 54 of back plate halve 12aa is received within the notch 62 of back plate halve 12kb, the joint element 58 of back plate halve 1211b is received within the notch 64 of back plate halve 12aa, the joint element 56 of back plate halve 1211a is received in the notch 66 of back plate halve12bb, and the joint element 60 of back.

plate halve 12bb is received in the notch 68 adjacent the Par tented Apr. 4, 1961 joint element 56 and the free end of back plate halve 12aa.

Each of the

joint elements

54, 56, 58, and 60 is provided with an aperture, namely

respective apertures

68, 70, 72, and 74.

Such apertures

68, 70, 72, and 74 are disposed in mating alignment in the assembled disposition of the slider Separator 28aa generally resembles the separator 28 of slider 10 except that in place of the blind hole of separator 28, the separator 28aa is provided with a pair of

upstanding lugs

76 and 78 disposed on the uppermost surface of the separator 28ml along its center line. The

lugs

76 and 78 are provided with

respective apertures

80 and 82 which in the assembled disposition of the slider 10 are disposed in mating alignment with the

apertures

68, 70, 72, and 74. The

lugs

76 and 78 are spaced from each other, so that the lug 76 will be received

intermediate joint elements

54 and 58 and the lug 78 will be received intermediate the

joint elements

56 and 58 when the slider 10 is disposed in its assembled disposition.

The back plate halves 1211a and 12bb are joined together by the drive pin 84 which passes through the

apertures

74, 70, 82, 72, 80, and 63. The relative dimension of the aforesaid apertures to the outside dimension of the drive pin 84 is such that the drive pin will be drive fit therewithin.

The back plate halves 12aa and 12bb are held together by the locking clip 48 which is received within the mating groove formed by the grooves and 52 on respective back plate halves 12m and 12bb in the identical fashion heretofore set forth in respect to the slider 10.

In the slider embodiment 10" shown in Figures 8 and 9, the back plate halves 12mm and 12bbb dilfer from the

back plate halves

12a and 12b of slider 10 in that in the uppermost portion, thecenter edges of the back plate halves 12mm and 12bbb abut each other along

edges

86 and 88, as well as along the

edges

32 and 34". However, intermediate the edge 86 and the edge 32 of back plate halve 12aaa there is provided a cutout portion having three spaced blind

tubular openings

90, 92, and 94 extending laterally inwardly from the edge 96 of such cutout portion. Similarly, there is provided a cutout portion intermediate the edges 34" and 88 of back plate halve 12bbb which is provided with blind

tubular openings

98, 100, and 102 which are opposite to the blind

tubular openings

90, 92, and 94, such blind

tubular openings

98, 100, and 102 extending laterally inwardly from the edge 104 of the cutout portion for a distance equal to the distance of penetration of the blind

tubular openings

90, 92, and 94.

The separator 28am for the slider 10" generally resembles the separator 28 of slider 10 except that in place of the blind hole 30 of separator 28 there is provided the strip 106 which projects upwardly from the uppermost surface of the separator 28am along the center line thereof. The strip 106 has a width dimension such that it substantially occupies the rectangular shaped opening intermediate the back plate halves 12am: and 12bbb when the same are assembled.

The strip 106 is provided with the three

posts

108, 110, and 112 which are received within the blind

tubular openings

90, 92, and 94 of back plate halve 12aaa, when the strip 106 is positioned alongside the edge 96 of the cutout portion intermediate the

edges

32 and 86 of the back plate halve 12am. The strip 106 is also provided with the

posts

114, 116, and 118 which are received within the blind

tubular openings

98, 100, and 102 when the strip 106 is positioned opposite the edge 104 of the cutout portion intermediate the

edges

34 and 88 of the back plate halve 12bbb.

The slider 10 includes the locking clip 48 which is received within the groove formed by the

grooves

50 and 52 when the slider 10" is assembled.

The assemblage of the slider 10" is accomplished by aligning the back plate halves 12mm and 12bbb in spaced juxtaposition to each other, with the strip 106 of the separator 2800a disposed intermediate the cutout portions in the back plate halves 12mm and 12bbb. The back plate halves 12mm and 12bbb are then mounted onto the posts carried by the strip 106. Thus, the back plate halve 12mm is mounted onto the

posts

108, 110, and 112 which are received within the blind

tubular openings

90, 92, and 94 of back plate halve 12mm. The back plate halve 12bbb is mounted onto the

posts

114, 116, and 118 which are received in the blind

tubular openings

98, 100, and 102 of the back plate halve 12171212. The bringing of the back plate halves 12mm and 12bbb together so that the edge 32" of back plate halve 12am: abuts the edge 34 of back plate halve 12bbb and the edge 86 of back plate halve 12mm abuts the edge 88 of back plate halve 12bbb produces the assembled slider 10", when the soassembled back plate halves 12aaa and 12bbb are locked together by the locking clip 48.

The sliders of the present invention permit rapid and facile assemblage by a garment manufacturer onto the slide fastener element carrying tapes when the tapes have already been sewn onto the cloth article. The use of the locking clip insures assemblage during the entire working life of the slide fastener.
