INVENTORS ZOU/JHMORI/V ATTORNEY be apparent that any means for accomplishing this result can be employed. 7
The element 22 has. two similar end portions 26, 24a that are yoke-shaped in form. That is to say, each end portion is provided with an aperture 25, 25a of a contour conforming with the peripheral contour of the links it, til and sufiiciently large to provide free passage of the links therethrough. The large rectangular apertures 25, 25a open outwardly through the ends 2%, 260. as seen at 2% forming inwardly directed top and-bottom flanges or hook ends it, Ella, ,adjacent surfaces of which are arranged in close proximity to the upper and lower surfaces of the tapes ill, Ii respectively inwardly of the beaded edges Illa, Ha thereof, allowing suficient clearance for the free passage of the element 22 over the tapes in the normal operation of the slider.
vThe flanges or hook ends it, 2M cooperate with the mounted end portions in, lid of the links M and id in retaining the slider against accidental opening movement when a lateral separating strain is subjected to the stringers i0, ii, tending to open (the stringers in the manner illustrated in Figs; 3, 4 and which would otherwise cause the slider to move downwardly along the stringers producing a separation or uncou pling thereof.
The lock element 22 may be termed a semiautomatic lock in that it is efiective in its operation under the conditions named, but does not lock the slider against normal upward and down- The lock element 22, which is in the form of an elongated plate or strap having similar end portions 261, 26a, may be correctly termed a see-saw lock, in that due to its swivel mounting on the pin or stud M, the separate end portions at, Ma. may be raised and lowered with respect to the beveled side surfaces its of the wide end it of the slider in the several manners illustrated in Figs. 1, 3, 4 and 5. Fig. 1 represents the normal or balanced position of the element 22 which is assumed when the slider is moved freely in both directions on the stringers in coupling and uncoupling the same. In Fig. 3 of the drawings, the end portion 26 is shown raised whereas the end portion 26a. is lowered, and the flanges or hooks 2? are shown engaging one of the links Q2 of the end portion 52a thereof in retainingthe slider against opening movement, or in other words a downward movement as viewed in Fig. 3 of the drawings. In Fig. 4 of the drawings the reverse of the arrangement shown in Fig. 3 is illustrated. That is to say, the end portion 26a is raised and the end portion 24 is lowered. In this position the flanges or hooks 21a engage one of the links it or the end portion 53a thereof in retaining the slider against movement.
In Fig. 5 is'illustrated another possible looking position or the element 22, which represents a position intermediate that shown in Figs. 1 and 4. It will be understood inthis connection that a similar intermediate position may take place between the position shown in Figs. 1 and 3. In Fig. 5 the end portion 240. is higher than the end portion 24 and the members 210 engage the portion I3a of the link 13, whereas the members 2'! engage the portion I21: 0! the link i2 to provide a double-check or look of the slider on both stringers.
It will be understood that while the end portions M, Ma have been shown as ofiset with respect to the central plate portion 22a of the lock element, that is to say leaning in the direction of the upper ends 16a. of the slider, that these end portions may be extended in any manner and may be arranged in the same plane. It is also quite apparent that the duplication of the members 2?, 21a is not essential. By this is meant, it is not essential that the members be arranged upon both the upper and lower surfaces of the stringer tapes it! and ii. As a matter of fact, one-half of the entire end portions 24, Ma which extend beyond the central plate portion 22a, may be omitted, thus leaving the central plate portion 22a with one end 243 and the companion end Eda. This is especially true in using a device oi the character defined in connection with supports which are subjected to light stress or strain. The duplication of the locking pins or flanges 21, 27a. is only for a purpose of providing the added strength attained thereby.
It is also apparent that instead of omitting the" upper or lower half of the element 22, either end portion of the element may be omitted; that is to say either the entire end 26 including the members 27, or the entire end portion 26a including the members am. In each case however, the plate portion 2241 will remain as an integral part or and form the support for the element. With the latter arrangement, it will of course be understood thapthe lock element would cooperate with onlyone of the stringers depending upon which end portion was utilized.
Still further it will be apparent that any one of the so-called hook elements may be used at either side or upon either surface of the separate stringers. That is to say, the supporting or mounting plate portion 22a would'be provided with one-half of either of the side extensions 2% or 26a including one of the associated pin-like elements 2?, 2M. I
The adaptations of the element 22 referred to above are not specifically illustrated in that their structure is quite apparent, especially when considering Fig. 2 of the drawings, applicants having elected to illustrate the complete or duplicated structure simply in that it represents the complete combination from which the more simpliiied forms of construction can be formed, and further in that it illustrates the stronger type of lock element.
"It will be noted from a consideration'of Figs. 3, a and 5 that the upper inner corner portions of each lock hook or flange 21, 27a are preferably rounded as seen at 28 so as to provide a free admission of the links i2, i3 through the element 22 when in the position shown in Fig. 1, even though the stringers are under a slight tension; in other words, in the operation of drawing two supports, to which the stringers are attached,
together under. a slight tension. The lower inner corners 29 of the members 2?, 21a will be maintained rectangular for positive engagement with the links i2, I! when the tapes I0 and II are subjected to a decided lateral pull tending of Figs. 6 and 9 of the drawings.
. smote manner. The only essential feature is that the element employed will engage a size:- or string,- J
ers at said end portion of the slider where the stringers are subjected to and capable of lateral movement in the manners illustrated diagrammatically in Figs. 3, i and of the drawings, and
further in providing a lock element of this type and kind which when in a neutral position will permit free movement of the slider longitudinally it, of the wall M has a contracted or pointed entension it upon the inner surface oi which is the usual connecting web ti which divides the wide end of the slider into diverging channels. In the construction shown, the slider is made from a unitary body, but it will be understood that any desired construction can be employed.
At 3% is shown the bottom wall of the slider which includes inturned side flange at. In this construction, the bottom wall terminates short of the top wall in an edge dd, but beyond the edge W the top wall extends in a relatively thin plate it in joining the connecting web ti. This plate is narrower in width than the width of the wall 38 at the end it thereof, as clearly seen in Figs. 6 and 9 of the drawings, forming recesses or spaces 2 at each side of the slider in which the book ends it, die of a lock element M are adapted to operate. a protruding coupling or pivot pin M which may be formed'integrally with the slider body or may constitute an independent pin secured thereto.
The lock element 44 may be said to constitute an extension of the bottom wall 38 of the slider. The contracted outer edge 41 of 'said element conforms with the contour of the contracted end fit of. the slider as will appear upon a consideration It will also be noted that the flanges 43, 53a at the sides of the element 44 actually constitute continuations oi the flanges 39 of the bottom wall. However, when the lock element is in a neutral position, these flanges will be spaced from the flanges 39 in that the edge 48 of the lock element is in spaced relation to the edge of the bottom wall.
It will appear from a consideration of Figs. 1
to 5 inclusive, that the lock element 2 2 consti-.
tutes a continuation of the wall structure of the slider and that the hook ends 211, 21a are contin'uations of the side flanges-of the slider, the
same as with the construction shown in Figs. 6
At the contracted end of the plate M is understood that this position is similar to the one shown in Fig. 4, d that the element M may also assume a position similar to that shown in Figs. 3 and 5.
By arranging the'element M in the bottom wall structure oLth'e slider, this element will be substantially invisible in normal uses of the fastener. It will also be. apparent that by terminating the flanges t t short of the wide end lib oi the wall til as seen 'at bi, a greater lateral movement of the stringers is made possible when subjected to stress or strain, which will produce a more positive looking engagement with the several links of the stringers, whereas when the element dd maintains its neutral position in the normal use of the device, the flanges (it, tiiia will serve to provide a smooth guiding of the slider along the stringers,
and especially in guiding the links into the diverging channels at the wide end of the slider.
It will be apparent that in both forms of construction shown, the lock element may be said to be extensions of one or both walls of the slider, and the lock parts or lnturned flanges of the elements, extensions of the flanges of said slider walls. These supplemental wall and flange parts which constitute the lock elements are movable with respect to the remainder of the slider so that either one of the flanges of the lock elements may be moved into and form an obstruction in the channel of the slider to engage a link of one of the stringers when the stringers are stressed or strained laterally as hereinbefore set forth.
