Description
This invention concerns improvements in quick-action fasteners.
There are known a large number of types of fasteners for use with
flexible, and optionally elastic, bands or tapes, formed for
example by hooks, snap hooks, plain rings, broken rings, pins and
the like, none of which are, however, wholly satisfactory or
versatile enough.
The quick-action fastening device according to one nonlimiting and
purely exemplary aspect of this invention includes a body and at
least one flexible element having at least one strand, the said
body having at least one main hole, at least one main window which
communicates with said at least one main hole and at least one main
slot which extends from the main window to one end of the main hole
and communicates with the latter, the maximum cross section of the
flexible element being less than that of the main window and the
minimum cross section of the flexible element being slightly more
than the width of the said slot, and mounting means for connecting
one end portion of the flexible element to said body, the other end
portion of which is connectable to any desired object.
It is possible to use widely different flexible elements such as,
for example, bands, cords, cables, laces, wires, ribbons, webbing,
elastic tapes and altogether any other flexible, and optionally
elastic, bands.

In all Figures, the same reference numerals indicate similar parts.
Thus, the body of the quick-action fastener is always designated 1,
a main hole 2, a main window 3 and a main slot 4. Reference numeral
5 indicates a single strand flexible element and the two strands of
a flexible element are marked 6 and 7, respectively. In all cases,
the cross section of a flexible element associated with a body 1 is
smaller than that of the main window 3 and the smallest cross
section of the or any or each strand of a flexible element is
slightly larger than the width of the main slot 4.
The body 1 may have any generally desired form, either cylindrical
and externally smooth (FIGS. 1 to 18, 20, 24 to 29, 31 to 37, 39 to
46, 53, 54, 62 to 68, 70 and 75), or a parallelopipedal shape
(FIGS. 22, 30), or cylindrical with external thread 8 (FIGS. 57 to
61), or any other shape (FIGS. 23, 38, 47 to 52, 55 and 56).
Moreover, the body 1 may be formed of one piece (FIGS. 1 to 18, 20,
22, 23, 26, 27, 29 to 31, 34, 38 to 45, 47 to 68 and 75) or from
several parts (FIGS. 24, 25, 28, 32, 33, 35 to 37, and 46).
The main hole 2 of the body 1 may be provided with an internal
thread 9 (FIGS. 28, 47 to 52, 60, 61, 63, 64, 68, 70 and 75).
Furthermore, the body 1 may be provided with a fastening element,
for example a hook 12 (FIG. 28), or a ring 13 (FIG. 60) or any
other suitable fastening element.
Additionally, over the whole length of the body 1 a slot 14,
separate from the partial main slot 4, may be formed (FIGS. 37, 62
to 67).
The body 1 may also have a second window 15, similar to the window
3 and a slot 16 similar to the main slot 4 and possibly opposite
the latter (FIGS. 26 and 65 to 67).
The means for mounting the flexible element associated with a body
1 in certain embodiments enable the rigid fixing of this flexible
element and in other embodiments the mounting means are such as to
permit its length to be adjusted relative to the body 1. These
mounting means may be formed as follows:
1. By an annular shoulder 17, arranged inside the main hole 2 and
coaxial therewith (FIG. 1), and defining a central passage through
which may pass the end of an associated flexible member 5 to be
fixed to the body 1 through the said end being folded back on
itself (FIG. 3). Alternatively, the said end may be tied or wound
by threads 18 (FIGS. 24, 28, 29), or equipped with a tightly
fitting ferrule 19 (FIG. 18), or knotted into a knot 20 (FIGS. 4,
33). This annular shoulder 17 also makes it possible to attach to a
body 1 a knotted end 21 of a two-strand element with strands 6 and
7 (FIG. 6). This annular shoulder 17 also permits the adjustment in
length relative to a body 1 of an elastic element 5 with a single
strand (FIG. 39), and with at least two strands 6 and 7 (FIG. 40),
by arranging that the cross section of the elastic element, when
extended to its maximum length, is substantially equal to the
diameter of the central passage of the shoulder 17.
2. By a shoulder formed by an abutment 22 projecting into the
interior of the main hole 2, partly blocking the body 1, and
permitting the fixing of a flexible element 5 by one folded back
end onto which is fitted a ferrule 19 (FIGS. 18 and 19).
3. By a shoulder formed by a flange 23 turned inwardly at one open
end of the main hole 2 (which may be a blind hole) of a body 1, and
permitting the fixing of a flexible element 5 by means of one
folded over end onto which is fitted a ferrule 19 (FIGS. 20 and
21).
4. By the choice of a bore size of the main hole 2 in the body 1 to
be such that the end of a flexible element 5, folded back on
itself, and optionally provided with a ferrule 19, can be pushed or
forced into this bore (FIGS. 22 and 23) and thereby fixed
therein.
5. By a shoulder which is coaxial with the main hole 2 of the body
1, integral with a detachable part 24 fixable to the body 1 by
threaded interengagement (FIG. 28) and acting in the same manner as
the shoulder 17, described above.
6. By a lateral slot 25 (FIGS. 42 to 45), provided in the body 1
and in two parallel, spaced-apart transverse partitions 26 and 27
in the body in association with an auxiliary window 28 opposite the
main window 3 and into which the slot 25 leads, so as to permit the
insertion of and the adjustment in length of an associated flexible
element 5. The element 5 may be elastic and includes enlarged parts
29, spaced at regular intervals along its length. In FIG. 45, there
is shown a mounting 30 in the form of a button 31 for anchoring one
end of the flexible element.
7. By a slot 25 provided in the body 1 in a transverse partition 26
inside the main hole 2 and in the base and the skirt of a cap 32
(FIG. 46). The cap 32 is mounted in a peripheral groove of the body
1, there being an auxiliary window 28 which is located opposite the
main window 3 in the body 1, and which communicates with the slot
25, so as to permit the insertion and adjustment in length of a
flexible element 5, which may be elastic, and which comprises
enlarged portions 29, regularly spaced along its length. Clearly,
the ability of the cap 32 to rotate prevents, by offsetting the
parts of the slot 25 relative to each other, the accidental
breaking away or removal of the flexible element from the body
1.
8. By an annular shoulder such as 17, cooperating with a threaded
button or plug 33 (FIG. 47), threadedly engaged with a thread 9 in
the body 1, there being an eccentric hole 34 in the plug 33. The
flexible element 5 is blocked by locking between the faces opposite
the shoulder 17 and the plug 33 when the latter is screwed in. The
flexible element 5 may be released and adjusted in length by
unscrewing the plug 33. The element 5 may be of single strand or
multiple strand construction.
9. By an annular shoulder 17 cooperating with a threaded plug 33
which is screwed into the thread 9 of the body 1 and has a pair of
substantially parallel holes 35 and 36 (FIG. 48), adapted
respectively to receive the two strands 6 and 7 of a flexible
element which is locked between the surfaces opposite the shoulder
17 and the plug 33 and may be adjusted in length by unscrewing the
plug 33.
10. By an annular shoulder 17 cooperating with a threaded plug 33
(FIG. 49), in which the plug 33 is screwed into the thread 9 of the
body 1 and has a peripheral axially extending groove 37 adapted to
receive a flexible element 5 which is locked and adjustable as
described in the preceding paragraph.
11. By an annular shoulder 17 cooperating with a threaded plug 33
(FIG. 50), wherein the plug 33 is screwed into the thread 9 of the
body 1 and has two lateral grooves 38 and 39 for receiving
respective strands 6, 7 of a flexible element which is locked and
adjusted in length exactly as in the three preceding examples.
12. By an annular shoulder 17 cooperating with an externally
threaded plug 40 which is screwed into the thread 9 of the body 1
which has an axial bore and a substantially conical gripping member
41 with a slotted resilient wall. The flexible element 5 is locked
and adjusted in position by screwing and unscrewing the plug 40,
the outer surface of the gripping member 41 being in contact with a
center passage of the shoulder 17.
13. By a substantially conical gripping member 42 having a
resilient wall which forms an extension of the body 1 along the
axis of the main hole; the member 42 cooperates with a cap 43 which
is screwed on to the external thread 8 of the body 1. The cap 43
includes an annular shoulder 44 and a central passage 45 in its
base to enable the flexible element 5 to be locked and adjusted in
position by screwing down and unscrewing the cap 43, the central
aperture of the annular shoulder 44 being in frictional contact
with the outer surface of the gripping member 42.
14. By two parallel, spaced-apart threaded plugs 33 (FIGS. 68-74),
each screwed into the internal thread 9 of the body 1. Each plug 33
has at least one eccentric hole 34 (FIGS. 68 and 69), which are not
aligned axially with each other; or a radial groove 37 (FIGS. 70
and 71); or several radial grooves such as 38 and 39 (FIGS. 73 and
74) to enable a flexible element 5 (which may have one or several
strands) to be locked and adjusted in length by screwing in and
unscrewing one of the threaded plugs 33. Alternatively, a threaded
plug 46 (FIG. 72) may be used, the plug 46 having a radial slot 47
and an outer, unthreaded portion 48 of larger diameter, permitting
it to be screwed in and to be unscrewed by hand. Similar and
self-explanatory plug and groove combinations are shown in FIGS. 75
to 78.
15. By radially spaced passages 49, 50 (FIG. 41) provided in a wall
blocking the main hole 2 of the body 1 and each adapted to receive
at least one strand 6, 7 of a flexible element which is in this
case elastic and which can, as described above, be adjusted in
length relative to the body 1, and locked in position, by
stretching and releasing the strands.
16. By a single threaded plug 33 which is screwed into the thread 9
of the body 1 and has either a center passage 51 (FIGS. 75, 76), or
several passages 35 and 36 (FIG. 48), or one radial slot 37 (FIG.
77), or several radial slots 38 and 39 (FIGS. 73, 74). The passages
51, 35, 36 and the slots 37, 38, 39 each receive at least one
strand of an elastic, flexible element, and each elastic strand
can, when fully stretched, slide under friction in the passage of
the slot in which it is located and can be locked in the required
position by releasing the tension.
17. By a deformable part 52 (FIG. 16) of the body 1 which in this
case is made of metal. This part 52 forms a tag and has serrations
or teeth 53 adapted to penetrate into the flexible element 5 after
the latter has been introduced into the part 52 which is then
deformed for locking.
18. By incorporating the end of a flexible element 5 into the body
1 during the moulding of the latter (FIGS. 9 and 15).
A utilization of the quick-action fastener shown in FIGS. 1 to 6 is
illustrated in FIGS. 7 and 8. Firstly, the axis of the body 1 is
brought into substantial alignment with that of a flexible element,
then the body 1, with the flexible element 5 mounted therein with
one end thereof secured, is inserted into an opening 54 of a wall
55, then the body 1 is rotated through 90.degree. while the
flexible element is forced through the slot 4 to enter the window
3; at this moment the direction of the flexible element is
perpendicular to the axis of the body 1 which forms an abutment
against the wall 55.
Obviously, the quick-action fastening device according to the
present invention may be mounted to any rigid or flexible object
equipped with at least one passage such as 54. For example, the
body 1 may be anchored at an angle defined by two bars of integral
construction.
FIG. 17 shows by way of example the use of a quick-action fastener
in conjunction with tying the lace 5 of a shoe 56. The lace 5 takes
the place of the flexible element and can be tied in the shoe by
threading it successively through the eyelets. In the transverse
locking position, loss of the lace 5 from the eyelets of the shoe
or boot is prevented.
Each end of a flexible element consisting of at least one strand
can be secured to a respective body 1 (FIGS. 10, 26, 34).
Alternatively, a body 1 can be secured to one end of a flexible
element, the other end of which is fixed to any object 57 (FIG.
11), for example, a button 58 (FIG. 31).
As shown in FIGS. 12 and 13, it is possible to use a flexible
element formed by a flexible belt which may be narrower at each
end. This construction is particularly suitable for forming a
removable handle 59 for parcels such as 60 or for other
objects.
In FIG. 30, the body is a rectangular parallelepiped and the
flexible element is in the form of a flat belt 61 which is elastic
and is articulated to the body 1 by a rivet 62.
As shown in FIG. 26, it is possible to mount on a flexible element,
secured to the body 1 at one or both ends at least one intermediate
body with two main slots 4 and 16 and two main windows 3 and 15.
Each of these intermediate bodies forms an additional fastening
FIG. 36 shows a cylindrical part 74 which is adapted to be
introduced into the part 70 and has one window 75 and one slot 76,
arranged in a bayonet-type arrangement. Rotation of the part 74 in
the part 70 causes the flexible element to be locked in the window
75 when the slot 76 is covered by the wall of the part 70.
FIG. 37 shows a modification in which the body 1 is formed by a
tubular element 77 which is slotted at 14 throughout its length,
and by two tubular members 78 and 79, slotted over their whole
lengths at 80 and 81, respectively. The slot 81 and the member 79
are covered by the wall of the tubular element 77, while the slot
80 of the member 78 acts as main slot 4 and as main window 3
together with the inner edge of the member 79. Such slots 14 are
shown also on the bodies 1 of the embodiments of FIGS. 62 to
67.
FIGS. 53 and 54 show an embodiment in which the flexible, and
optionally elastic, element 5 has projecting parts 82 of triangular
cross section regularly spaced along its length, and the body 1 has
two rectangular passages 83 and 84 which, in one position, permit
the free sliding movement of the flexible element 5 and in another
position, offset from the first position by an angle of 90.degree.,
block the flexible element 5 by engaging two of its projecting
parts 82.
In cases where the flexible element 5 has projecting or enlarged
parts 29 (FIGS. 42, 44, 45, 46) or 82 (FIGS. 53, 54), the main slot
4 has an enlarged part, permitting the passage of the projecting
portions 29 and 82 for locking the flexible element on the body
1.
The body 1 can be formed with an integral hook (FIGS. 23 and 55) or
with an integral eyelet (FIG. 56). Different examples of external
threading are shown in FIGS. 57 and 59, respectively.
In FIG. 25, the flexible element 5 is threaded through a sleeve
through which passes a grubscrew for locking the element 25.
