' :s Claims. (c. cuan :The present' invention refers-:to:certaintimprovements in continuous lnear closing devices, particularly of :the kind consisting of :plastic material-:and provided withthe necessary 'means for bringing-about mutual interl'ocking i of adjacentparts which -in this mannerrare "definitely fastened. I I

;Many :devices of the-'kind specified' are already known to provide a close and-safe. fastening, being 'employed,

or at least being provided, for' 'the purpose of advantageously replacing the so-called zip fasteners. In this,.however, the 'zippers havebeeduns'uo'cessful due to lack of precision and tightness in the manufacture of the devices, 'or due 'to deficient arrangement of the component. parts.

` I`n fact, .it will be 'recognized that'the parts-andarrangement thereof so farproposed as-'entirely novel,'con1- ;prisng longitudinal ribbon-like stripsintegrally provided with anchor orsimilar looking-and-engagng means, have :not yet given .proof of being entirely safe or, 'whatds the same, their complete and secure closure is not always subject to the' users will. 'It-'happens thus that the parts arranged for. proper lockingcome apart quite-easily, :particularly in view of the flexibility'o'f strip-like members, which -therefore become readily;displaced, individually or together. The consequence of this is that the device opens, with resultant effects on the article of Clothing or other object to which the fastener is applied.

The device according to the present invention, on the contrary, is provided with substantially improved means greatly superior to all such arrangements known or used to date. These improvements, object of the present invention, consist in providing the strips of plastic or similar material constituting the support at each side of the fastener, with a pair of looking members arranged, on the one side, at the edge of the supporting 'strip and, on the other side, in a region close to said edge and parallel thereto, representing an intermediate longit udinal band of a substantially flexible nature and which, in combinaticn with the respective pairs of confronting members and a further member speoially formed for greater relative flexibility, enables a tight closure to be obtained, only to be loosened at the user s option. Said looking or anchoring efiect is obtained automatically or by means of a runner specially furnished for connecting or disconv necting the looking members. This runner is not essentially necessary for the operation of the present closing devioe.

The invention likewise envsages other accessory objects, as will be made clear in the course of the present description.

In order that the present invention may be more readly understood and put into practice, a preferred embodiment thereof has been illustrated in attached drawings, in which:

Figure 1 is a diagrammatic and cross-sectional View of a pair of strips arranged as looking supports, showing the manner in which one is adapted to the other.

Figure 2 is a likewise sectional view of the' devce adapted to a-complemeitary runner member, if the use of such` is-'preferre'd, `'illus'trati'ng' the manner in which'one 'of-the' locking members is offset -to' connect with its counter-part. 5 Finally: v

` `Figure 3 illustrate's a *lengthwise-part section 'of the looking device provided with-a runner member, 'following line A-B of Figure 2.

Like'numerals represent like or-similar parts-throughout the" several figures o'f the'drawings.

With reference to the embodiment illustrated `in the drawings, the zipper'object of-the present invention com- 'prises supporting bands-or strips --1 arranged for mutual 'overlapping 'along their edges and the 'portions adjacent thereto, in "order to fulfill their' essential purpose. -Each of said bands or strips at its *corresponding edgesis shaped with a pair of locking'members 2, 3, -'4 and 5, respectively arranged in pairs and substantially faoing-one another-so as to leavebetween 'each-pair of members a 0 'strip' defining -a-` flexin`g *zone tor `secure 'looking of the I 3 'said members once'sar'ne have been connected, thus pro- -vidingyawell-defined 'stabilizing area in the position 'occupied by the'locked members.

As can 'be seen inthe Fig. 1, hooklike looking mem- '*ber 3'has a Vertical portion extending upwardly from strip '1, and an integral horizontal end -portion fa'cing locking member 2. 'Looking-member 2 has a vertical `-por`tion^exte`nding upwardly from strip 1, an integral 'hori- "zo'ntalportion extending in 'the directionof looking member '3, said 'h'orizontal *portion terminating in an integral verticalend portion downwardly directed and facing strip '1. It -is thus seen that hoo'k-like looking members 'generally faceeach other, although their ends define planes `approximately `90 'with 'respect' to each other.

T- hS-arrangementcan 'be' clearly seen in -Figures' '1 ;and :2, particularly in Figure '1, illustrating the manner in which the locking'members are arranged. Membersz 'and 3 represe'nt "the `'re'eeivi'ng''p'arts of oneof the "strips -(1 complemented `*by 'equivalent counterparts of 'the opposing strip. In order to bring about looking action, member 2 must be olfset, which ofisetting is made possible by the provision of a flexing part obtained by reducing the thiokness of the strip in that area, said reduced portion forming a channel 6, as shown in Figure 1.

In case it should be preferred to use an additional member for bringing about looking action, a runner 7 can be provided, having an interposing member 8 which is run between the two parts 1 of the zipper, particularly between the adjacent edges of looking members 2-3, on 0 the one hand, and 4-5 on the other. This runner 7,

in the hollow corresponding to member 2, is provided with a chamfered part, in such a manner that during displacement it produces a slight ofsetting of the looking member, as seen in Figure 2. This oifsetting is clearly favoured by the thinner section 6, the entire arrangement permitting free disposal of the strip edge of member 4-5 and nearby area, between the two `complementary members 2- 3. Once the runner has passed, the interlocking position of the members is ensured inasmuch as members 3 and 5 constitute the looking parts and members 2 and 4 the holding or retaining parts thereof, thus completing the closure.

It should be clearly pointed out that the members or means furnished to provide flexibility to the whole, can

be summarized as represented by slit 6 which, in turn, is substantially formed by a particularly reduced section arranged to form a substantially resilienthinge. This feature has a double purpose: that of permitting separation of member 2 in order to insert the counterpart of the opposite strip,

and of preventing unlooking of mem V bers 3 and 6 when subject to tension or traction in length- I wise direction to the planes of sections 1. t 'Under 'these i circumstances the set of members 2 and 4 cannot come assembly. This cloth or other appropriate similar material is incorporated in the strip thermally or through some other process enabling both materials to be joined integrally.

The invention in the manner described and illustrated may be clearly understood and further explanations will not be required by those versed in the matter.

Inasmuch as sundry changes as to construction and detail may evidently be introduced without thereby departing from the real nature of this invention, it is to be understood that the description and drawings are in no way limitative or restrictive, the scope of the invention being clearly defined in the following claims.

What we claim is:

1. In a continuous fastener combination comprising a pair of supporting strips provided with cooperating hookshaped sections longitudinally disposed for mutual engagement and separation, the improvement wherein one of said supporting strips has laterally spaced longitudinally extending hook-like locking members, said book-like locking members generally facing each other, the inner surfaces of said hook-like locking members termnating in planar surfaces approximately 90 With respect to each other, said inner surfaces dening the hook-like shape of said hook-like locking members, the book-like locking member remote from the end of said strip having a portion of increased fiexibility disposed in the region of said book-like member where said hook-like member joins said strip, the other of said strips having an edge portion complementary'to the space defined by said hooklike locking members one of said planar surfaces being generally perpendicular to the plane of its supporting strip, and the other of said planar surfaces being generally parallel to the plane of the same supporting strip.

2. In a continuous fastener combination comprising a pair of supporting strips provided with cooperating hook shaped sections longitudinally disposed for mutual engagement and separation, the improvement wherein one of said supporting strips has lateral-ly spaced longitudinally extending book-like looking members, the book-like locking member nearest the edge of said strip having a vertical portion extending upwardly from said strip and an integral horizontal end portion extending toward the other hook-like locking member on said strip, said end portion having a horizontal planar surface facing said strip, said other book-like locking member having a first vertical portion extending upwardly from said strip, an integral horizontal portion extending in the direction of the first book-like looking member and termnating in an integral vertical end portion downwardly directed toward said supporting strip, said end portion having a vertical planar surface facing said first vertical portion, said second hook-like looking member having a portion of increased exibility disposed in the region where the upwardly extending vertical portion joins said strip, the other of said strips having an edge portion complementary to the space defined by said hook-like looking members.

3. A continuous fastener combination as recited in claim 2 in which said portion of increased fiexibility is constituted by forming the portion of said vertical member of increased flexibility thinner than the remainder of said hook-like locking member.
