3,029,854 EXPANDIBLE CLOSURE DEVICE Anthony J. Burniski, Warson Woods, Mo., assignor to Prince Gardner Company, Inc., St. Louis, Mo., a corporation of Pennsylvania Filed Liane 27, 1960, Ser. No. 38,776 9 Claims. (Cl. 150-39) The present invention relates generally to fastener means and more particularly to fastener means employed on leather goods products and the like.

Various fastener devices have been constructed in the past and some have even included means for increasing or decreasing the capacity of a closure wall such as the wall in a billfold, card case, or similar device. For the most part the known devices have included a plurality of spaced snap fastener members mounted on one wall panel and a fastener member on another panel which is selectively engageable therewith. Selection of one of the spaced fastener members provides means for adjusting the capacity of a device. Such devices are relatively expensive to make, are not self-adjusting, and are limited by the number of spaced fasteners provided. For these other reasons the known devices are unsatisfactory. These and the other disadvantages of the known devices are overcome by the present expandible closure device which includes a pair of cooperating snap fastener members mounted respectively on a pair of Wall panels, one of said members being slidably mounted in a track on the associated wall panel to change the relative positions of said panels when fastened together.

A principal object of the present invention is to provide relatively inexpensive means for adjusting the connection between wall members.

Another object is to provide self-adjusting fastener means for fastening together a pair of wall panels, such as the wall panels on a card case, billfold, purse or similar articles.

Another object is to provide means for increasing or decreasing the capacity of card cases, billfolds, purses and the like,

Still another object is to provide self-adjusting fastener means which are relatively easy to construct and install and which require no special skill to operate.

These and other objects and advantages of the present invention will become apparent after considering the follOWing specification in conjunction with the accompanying drawings, wherein: 1

FIG. 1 is a face view of the inside of a billfold and card case constructed according to the present invention, the card case being shown closed in solid outline and open in dotted outline;

FIG. 2 is a fragmentary view of the billfold portion having the card case, the view being taken along line 2-2 in FIG. 1;

FIG. 3 is a fragmentary view similar to FIG. 2 showing the card case expanded to take care of increased capacity;

FIG. 4 is a fragmentary plan view of a wall panel having an adjustable snap fastener thereon constructed according to the present invention, said fastener being shown in an alternate adjustment position in phantom outline;

FIG. 5 is a fragmentary cross-sectional view taken on line 5-5 of FIG. 4;

FIG. 6 is a fragmentary perspective view of the card case and adjacent billfold portion of HG. 1, the card case being shown open;

FIG. 7 is a fragmentary view of a panel having a modified form of mounting the adjustable snap fastener of FIGS. 16;

FIG, 8 is a view taken of the opposite side of the panel of FIG. 7;

United States Patent 0 FIG. 9 is a fragmentary cross-sectional view taken on line 9-9 of FIG. 7; and

FIG. 10 is a perspective view of an open card case having an adjustable snap fastener constructed according to the present invention.

Referring to the drawings by reference numbers, the number 20 in FIG. 1 refers to a billfold having a card case 22 mounted on an inner wall thereof as shown. The card case 22 has a foldable outer wall 24 with two overlapping closure panels 26 and 28. The panel 26 is the outer closure panel and has a female fastener member 30 mounted thereon.

The panel 28 is the inner closure panel and it folds behind the panel 26 and carries a male fastener 32 (see FIG. 5). The male fastener 32 has a fastener portion 33 and also has two spaced flange portions 34 and 36 which are connected by a stem 38. The male fastener 32 is slidably mounted in a track constructed in an opening 40 in panel 23. The track is formed by a pair of spaced U-shaped track members 42 and 44 which are mounted on opposite side edges of the opening 40. In the case of a card case or similar leather goods device,

the track members may have flanged edge portions such as the rounded edge flanges 46 (FIG. 5) which are compressed into engagement with opposite surfaces of the panel 28 and provide a smooth connection therewith.

The flanges 34 and 36 on the fastener 32 engage opposite sides of the track members 42 and 44, and can be moved back and forth along the track in the opening 40.

In FIG. 2 the card case 22 is shown closed about a plurality of card windows 48. In this illustration, rela tively few card windows 48 are shown in the card case, and the fastener 32 is positioned in the opening 40 ad jacent the rightward end thereof. In FIG. 3 the number of card windows 48 is substantially greater than in FIG. 2, and the male fastener 32 is in a position nearer to the left end of the opening 40. FIG. 4- also illustrates two extreme positions of the male fastenermember 32 in the opening 40.

FIG. 6 shows the card case 22 open with the male member 32 at an intermediate position.

It is understood that the male and female members 30 and 32 can be interchanged without changing the nature of the invention, and it is also understood that either or both fastener members 30 and 32 may be movable in openings or tracks for greater adjustment.

A modified form of track structure 50 for. a movable fastener 62 is shown in FIGS. 7-10. The modified track structure 50 is similar to that described above but differs therefrom because it is of one-piece construction instead of two-piece construction. The structure 50 has a smooth surfaced wall portion 52 which engages one surface of a panel 66, and a pair of flanged portions'54 and 56 which are formed to engage the opposite edge portions of an opening 58 in the panel 66. The flanged portions 54 and 56 are integral with the wall portion 52 and are originally formed substantially at right angles to the portion 52. During installation the flanges 54 and 56 are bent around corresponding edge portions of the panel opening 58. In this way they form two spaced and substantially U-shaped cross-section tracks similar in construction to the track members 42 and 44 of FIG. 5. The free edges of the flanges 54 and 56 and the free edge of the wall portion 52 are also flanged to more securely engage the associated surfaces of the panel 28, and eliminate rough edges. The ends of the structure 50 can also be rounded for appearance as shown. It is also contemplated to use many different shapes and patterns for the subject track forming device, and it is contemplated to round the ends of the track opening 58.

FIG. 10 shows a modified card case 60 with the slidable male fastener 62 mounted in the track structure 50 on the panel 66. In the modified structure, the female fastener 68 is mounted on the panel 70 which is positioned behind the panel 66 when the case 60 is closed. Hinged connected window sections 64 are mounted on the card case 60. The, modified card case 60 is shown to illustrate one of many possible variations of the device.

It is also contemplated to mount the movable fastener in an opening in the panel without providing any separate track forming means. In such case it maybe desirable to stiffen the panel adjacent to the side edges of the opening to facilitate movement of the fastener and to prevent the fastener from working loose.

The present device can also be used on many other articles in addition to those shown and described herein, including many articles in the plastic, cloth and leather goods fields.

Thus there has been shown and described several preferred forms of a fastener device for increasing or decreasing the interior capacity of an article such as a card case or the like. Many changes, variations, modifications and uses of the subject device will become apparent to those skilled in the art after considering this specification and the accompanying drawings. All such changes, variations, modifications and uses which do not depart from the spirit and scope of the invention are deemed to be covered by the invention which is limited only by the claims which follow.
