INVENTOR R E N R V N A M R E H FIGJ ATTORNEY Patented Apr. 28, 1953 UNITED STATES PATENT OFFICE ADJUSTABLE ATTACHING DEVICE Herman Vizner, Brooklyn, N. Y. Application September 11, 1950, Serial No. 184,310

' (Cl. 24-20s) 3 Claims. 1

i This invention relates to improvements in adjustable fastening devices, including a trackcomprising a-plurality of spaced stops, or the like, supported in a flexible manner, and a cooperating member slidable over the track and adapted to be selectively locked to the track in various lengthwise positions against movement on the track.

An object of this invention is to secure a row of hexagonallly shaped fastener elements in a linear row to a flexible fabric strip, and to mount a clasp in slidable relation on the strip, and the clasp having resiliently mounted rotatable detents for selectively interlocking with the sides of the hexagonal fastener elements.

. Another object of this invention is to form parallel lateral walls inside the clasp for guiding the clasp in alinement with the row of fastener elements.

Another object of this invention is to provide a cover having an inverted U-shaped body portion co-extensive internally with the Width of the clasp when in closed position, and being pivotally mounted on the clasp body to retain the resilient side walls of the clasp body in closed position and the detents in interlocking relation with the track and with the clasp.

With the above and other objects in view, the invention will be hereinafter more particularly described, and the combination and arrangement of parts will be shown in the accompanying drawings and pointed out in the claims which form part of this specification;

Reference will now be had to the drawings, wherein like numerals of reference designate corresponding parts throughout the several views, in which: 1

Figure lvisa side elevation of a fragmentary portion of an adjustable fastener embodying one form of the invention.

Figure 2 is a top plan view of the adjustable fastener shown in Figure l, and showing a clasp partly broken away to show ball-shaped detents in operative engagement.

Figure 3 is a top plan view of the clasp, with the cover in open position, and the detents just sliding over the fasteners.

- Figure 4 is a top plan view of a modified adjustable fastener element in entirety.

Figure 5 is a cross-sectional view taken on line 5-5 in Figure 4.

Figure 6 is a side elevation of a fragmentary. portion of the modified adjustable fastener shown in Figures 4 and 5.

In the illustrated embodiment of the invention shown in Figures 1 and 2, the numeral ID indicates an adjustable fastener comprising an, elongated strip of flexible fabric II and a linear,

row of fastener elements l2 forming a track l3.

Each fastener element I2 is preferably made of metal of generally hexagonal form in plan view, and having a low linear central portion l5 contacting the strip II, and two side portions 16 raised to an elevation slightly above the strip H. Each fastener element [2 has two sides l! in right-angular relation with the track I3 and in adjacent relation with the following fastener element. 3

Two side walls of each of the fastener elements [2 form obtuse-angular lateral extensions l8'and portion of which are two parallel linear transverse walls 28 for guiding the clasp in with the row of fastener elements 12.

Two balls 30 serving as detents are mounted inside the clasp 24, between the

resilient side walls

26, 26, and two adjoining inclined wallsof adjacent fastener elements I2. The halls cause an interlock between the clasp 24 and the'track A cover 3| is pivotally mounted on" the' clasp body 25 on pins 32. As best shown in Figureg2, the cover 31 terminates at one end in a,loop'33-. It is to be noted that the; upper wall and the base 21 of the clasp body 25 have linear openings 35 therethrough and that during manufacture, the loop -33 is formed so as to normally urge the side walls toward each other. The cover engages the clasp body in frictional relation.

The cover 3| is of generally channel-shaped cross-section and has two arms 31 pivotally mounted on the pins 32. When the cover is swung into covering relation with the-clasp body 25, it retains the

side walls

26, 26 in close contacting relation with the detents 30, that is, when the detents are respectively in contacting relation with two adjoining angular sides of the fastener elements [2.

In operation, the user grips a projection 39 at the free end of the cover 3| and exerts an upward pull on the cover and brings the cover to the position shown in Figure 3. 'Inthis' posialinement tlon, the user grips the cover 31 and pulls the clasp 24 in a direction lengthwise of the strip H, permitting the detents to ride up or rotate to the vertices of the obtuseangular lateral extensions on the fastener elements E2. The detents cause the free end portions of the opposite halves of the clasp body 25 to spread apart, to permit the movement of the detents.

It is to. be noted that upon closing the cover 31, the detentsare forced into interlocking engagement between the side walls 28 and two angular sides of the fastener elements.

It is to be noted that the detents 3i) rotate during their movements in the clasp 24 and this.

rotation reduces friction. The track i3 is generally fiat and of very little height; The loop portion 33 of the clasp body this made resilient to permit the free end portion of the-clasp to move to and fro, laterally to open up' when passing the high points on the track.

Figures, 1 to 3 inclusive show an adjustable fastener 10 having a track I 3' with'two zig-zag sides or lines 28 made by forming opposite sides of the fastener elements 2 with obtuse-angular projections [.13.

Figures 4 to 6 inclusive show a modified adjustable fastener 49 having a track 4! wherein the fastener elements 42 have projections 43 which are convexly rounded or made semi-circular. This form of track 4! provides two substantially zig-zag sides 44 and a zig-zag operating efiect. The fastener elements 42 are mounted.

on a flexible strip 45'.

-Each fastener element 42 is preferably made of metal, and has a low linear central portion 46 cent sides 48. Stitching 22' passes through the:

slots. and through the fabric strip 45 and se-- cures-the. fastener elements 42 to the strip 45.

1 Aclasp 54 having a body 55 of generally rectangular cross-section and having two

resilient sidewalls

56, 56,, is slidably mounted on the strip 45. The clasp 54 has a base 51.

Two disks serving as detents are mounted inside' the'clasp- 54. between the resilient side walls '56, .56, and two adjoining" convex walls of adjacent fastener elements 42. The disks 60 cause-an interlock between the'cl'asp 54 and the track 4!.

A- cover 6! is pivotally mounted on the claspbody 55 on pins 62. As best shown in Figure 4, the cover 6| terminates at one end in a loop 63. It is to be noted that theupper wall 64 and the base51 of the clasp body 55 have linear openings 55 therethrough and that during manufacture, the loop 63 is formed so as to-ncrmally urge the sidewalls toward each other. The cover engages the clasp body in frictional relation.

5 The cover 6! is of generally channel-shaped cross-section and has two arms 61 pivotally mounted on the pins 62. When the cover is swung into covering relation with the clasp body 55', it causes the

side walls

56, 56 to be in close contacting relation with the disk detents 60..

when the detents are respectively in contacting relation with two adjoining convex sides of the fastener elements 42.

It is to be noted that the raised horizontal sides of each fastener element permit the base portions of the clasp body to ride thereunder and prevent disengagement of the clasp body from the fastener elements.

It is also to be noted that the parallel upright sides of each fastener-element retain the clasp body against any wobbly motions.

It is also to be noted that each disk-type detent 60 has a pin 60 freely passing therethrough and centrally thereof. The upper and lower ends of the pin 89 are suitably secured in apertures in the upper wall 64 and in the base 51 of the clasp body 55 In accordance with the patent statutes I have described and illustrated the preferred embodiment of my invention, but it will be understood that various changes and modifications can be made therein without departing from the spiritv of the invention as defined by the claims.
