This invention relates to separable fastener stringers
employing scoops for coupling and uncoupling the string
ers. More particularly, the invention deals with devices
of the character described, wherein the scoops have at
mounting end portions thereof angularly offset heel por
tions. Still more particularly, the invention deals with
a scoop structure of the character described, wherein the
scoops, plus the ‘offset heel portions thereof, establish
on each stringer a grip or anchorage extending the full
length of the stringer, thereby providing a strong and
durable stringer construction.
The novel features of the invention will be best under
stood ‘from the following description, when taken to—
gether with the accompanying drawing, in which certain
which the ?anged sides of conventional sliders operate
in the operation of coupling ‘and uncoupling the string
ers and, thus, prevent wear upon the stringer tapes. The
scoops 12, 12’ are die cast directly upon the stringer
tapes and, in the pressure injection of the material into
the die cavities, it will be understood that this material
extends into the interstices of the braid of the tape
in establishing a very secure anchorage of the scoops
on the tape, as well as the beaded edge 11, 11’. It will,
thus, be apparent that no attempt has been made to il
lustrate the roughened surfaces of the casting in FIG. 3
of the drawing.
It will be understood that the ?anged sides of the
slider, in operating upon the heel portions 19, 19', en
gage the rounded ends 22, 22’ of the end portions 18,
18' in drawing the scoops 12, 12.’ toward each other in
the coupling engagement.
For purposes of description, it may be said that the
offsetting of the heel portions [to one side of the scoop
is equal or substantially equal to spacing between op
posed surfaces of the mounting end portions of the
pair of stringers coupled together with my improved scoop
scoops, the result of which would be that the mounting
end portions or’ the scoops arranged upon the beaded
edge of a stringer tape can be said to collectively ex
tend the vfull length of the tape, so that stresses or strains
tending to separate the stringers are taken up throughout
structure.
the entire length of each stringer through the scoops at
embodiments of the invention are disclosed and, in which,
the separate parts are designated by suitable reference
characters in each of the views and, in which:
FIG. 1 is an enlarged diagrammatic plan view of a
