(Cl. 24d-201) l This invention relates to slide fasteners for connecting, attaching or coupling parts, structures orctabricsf ina -releas'able manner.r The usual. orms. of' slide fasteners. consist, of two 'sidefor'edge eiementspeachk of whichis secured along'the twofedgesoff the openingto be closed,

'ancla` sliding member to'ieect ther engagement and disengagement-ot same. Inthese types.` one edgeelement isv trapped 'into the, other by gradfutil-1r.forcing; them' togetherand lkeepingl them engaged-bygmeans off close tolerances between 'the twg-members;

, A'l'."t 1e;.present invention has` beendevised topro.- vide a 'new' typeof slide.fastener,l which lends itself to-a wide range of application, is easy to niarpulate and notrliable to failure. A further purpose ofthe -invention isV to furnish a more positive and safer form of fastening, yet allowinggreater tolerances.

.According to *theA present invention, the slide fastener consists broadly of three parts: Athe receiver element-'containing a jaw vportion with'. an

opening into the, jaws at oneside edge thereof,

such element' extending` along the side of the opening'infan article to which the fastener is to vtieiltted, and saidvjaw portion also containing a lockingfmember or device; an injector element to be. securedftothe other side edge of the opening. 'ofi the `article f and. extending therealong, having, an. engaging formation along its outer edge 'engage inside the jawporticn of saidreceiver element "where itA is locked in placefby said lockins. member or device and Va slider, movably mounted'on said receiver element, andA directing theifnjector element, in. and ont from they jaws o'f said receiver element.

In ordenthatthe invention may be fully understood, reference is made to the accompanying drawings wherein:

Fig. 1 is a perspective. View of the receiver element.

Fig. 2 is a perspective view of the injector element,

Fig. 3 is a .perspective view of the slider,

Fig. 4 is a perspective view of the locking member,

Fig. 5 is a perspective view of a modification of the locking member,

Fig. 6 is a perspective view of the assembly of the slide fastener with the slider shown in Fig. 3,

Fig. 7 is a section taken alone line 1 1 of Fig. 6. Another embodiment of the invention is shown in Figures 8 to 14 in which: i

Referring tofFigur'es .I to 7i inclusive, the/receiver elem'enti's's'hown inFig. 1. This isroughliI of Vrectangular channel shapefa-ndi maybe formed many suitable way, such'as pressing 'or extrud- Aing, casting, or otherwise, of metalyplasticf or other appropriate material.

The injector element is shown in Fig. 2, and is` made of any suitable.material'` which ensures sucient flexibility, suchas metals--andplastics While provision. for attachment ofveither 'the receiver, or injector elementsito. an. article isnot shown in the drawings, this may be effected. by sewing, welding,V riveting or otherwise, depending on' the material toi whichythefastener isto .he

applied.

Fig. 3 shows slider -c-,and Figures 4 andz show the. locking member -.-e+- and -el..-re spectvely. When made.v of"r onepiece, astinlliig. Il,

.it should be of-fleXib1e material, such asfplastic.

I prefer, however, to. use it inthe form..shown.in

Fig. 5, consisting of several. sections'.`

4'Ioiully understand the function of, all members, it: is advisable toconsider'Fig. '7.y showing the fastenter` fully assembled. RidgeA 111,- of the. injector element -bis located in the groove against the. side. e2- of vsaid locking member. This ridge -blmay t loosely or rmly in said groove alaccording to. tolerance required. Intermittent endwise fixations are possible; by aseries of',l shallow. impressions and protrusions coinciding with said ridge and groove, although by blocking the ends of the receiver element aendwise movements can be eliminated. Said locking member -esits against and along face -a2- and is held in position against shoulders -a5- of receiver element aby spring -f. As there is no possibility of the injector element dislodging said locking member -e-, the union of the fastener is positive and unreleasable without other means.

, Groove -aB- of said receiver element -ais to be mounted. ASpring ,fis preferably a leaf spring and located in the upper cavity of said receiving element -a on top of locking member -e-. In the modification of locking member -elshown in Fig. 5 groove e3- is provided to locate said spring f-, although this is not absolutely necessary.

In Fig. 6 the fastener is shown in operation. By moving sliding member -cin the direction towards the rear of locking member -a, the fastener will be opened, While reverse movement of the slider -ccloses same. The processv is the following: Slider -cis slidably mounted on receiver element -a-, and the inclined surface -cE- located on said sliding member -c, gradually dislodges area after area, or section after section of the locking member -eor -elrespectively, thus freeing section after section of ridge -bland leading injector element -bin or out through opening -e3-. This opening -03- has a down and outward direction in the illustration shown.

Another construction embodying the invention is shown in Figures 8 to 14 inclusive in which injector element -b-, receiver element -a-, kslider -cand locking member -eand -elrespectively are all similar tothe cor responding parts shown in drawings Figs. 1 to '7, differing from same mainly in arrangement.

To fully understand this second embodiment "of the invention shown in Figures 8 to 14, it

is advisable to consider Fig. 14 showing the fastener in closed position. Ridge bl- Y of injector element b is located in groove alof the receiver element afand is trapped in said groove aI- by locking member -c-or eI- Which is located inside of the receiver element zi- The locking member -cis below and along groove -alof said receiver element a-, and ridge -btof said injector element -b-, positively blocking the only exit from said ridge. Provision is not shown for retaining said looking member -e within said receiver element afin disengaged position,

-as this can be eiected in many different and simple ways, such as ridges inside of the receiver member -a-.

Fig. 13 shows the fastener in operation. Moving vslider -cin the direction towards the rear of locking member -aopens the fastener, and opposite movement closes same, as follows: slider -cis slidably mounted on the receiving elecated ;on the end of slider -cgradually dislodges section after section o-f locking member -esupported by leafspring -f, thus freeing section after section of said ridge bland leading it in and up, or down and out, through opening c3- which is shaped to take in said ridge.

It is believed from the above description and 'said receiver element.

4 attached drawings that those skilled in the art will full;r understand the construction and operation of the device which is readily adaptable for a great variety of applications. Of course, changes in the form or size of parts, or their arrangement may be made, different means for the mounting of the device to the surfaces to be joined may be selected, without departing from Vthe spirit of the invention which is not limited to the speciiic mechanisms shown and described, and from which departures may be made Within the scope of the accompanying claims.
