Abstract
A button snap flap closure for a pocket having a flap which overlaps a surface of the pocket.

Description




BACKGROUND OF THE INVENTION




1. Field of the Invention




This invention relates to button-snap flap closures.




2. Description of Relevant Art




Button-snap pocket flap closures now in widespread use have several serious limitations when used in military applications. They are difficult to close with one hand. They are difficult to close in an environment where it is not possible to visually align the snap's circular top and bottom halves; the mating halves must be precisely aligned on both the x and y axes to lock. The attachment points are not adjustable. The flap cannot be secured tightly over the pocket's contents if the volume in the pocket changes. For example, a pocket flap designed to carry three ammunition clips will allow two clips to bounce and rattle as the soldier moves. The present invention is directed towards eliminating the aforementioned limitations of the prior art button snap flap closures.




SUMMARY OF THE INVENTION




The invention provides a pocket flap closure that can be easily opened and closed with one hand, can be used without looking and allows the flap to be tightened as needed to minimize noise and movement of various pocket contents.




Broadly the invention comprises a button snap flap closure for a pocket having a flap, which flap overlies a surface of the pocket. The closure comprises an elongated keeper which keeper has a ridge characterized by longitudinal ribs formed on its sides and locking teeth on its upper surface.




A block-like clip is secured to the underside of the flap. The clip has a top portion and depending sides with inwardly extending locking teeth. The underside of the clip has a locating recess formed therein. The flap is pulled taught, the clip is pushed into the keeper, the locking teeth of the clip snap over the ribs of the keeper and lock the clip to the keeper. A locking tooth on keeper engages the recess in the clip to prevent movement of the clip along the longitudinal axis of the keeper.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS




Referring to

FIG. 1

, a pack


10


is shown and comprises a pocket


12


, having a front panel


14


and a rear panel


16


. A flap


18


is formed integrally with the rear panel


16


and extends over the front panel


14


. A clip


20


is secured to the underside of the flap


18


and a keeper


40


is secured to the outside of the front panel


14


.




The clip


20


can be secured to the keeper


40


at any location along the longitudinal axis of the keeper


40


. As shown in

FIG. 2

, the snap


20


is secured to the top of the keeper


40


with a full pocket


10


. As shown in

FIG. 3

, with the pocket


10


only partially full or empty the snap


20


is secured to the lower end of the keeper


40


.




To secure the clip


20


to the flap


18


, referring to

FIG. 4

, pins


22


extend from a plate


24


, pass through a strap


26


and the flap


18


(fabric) and are then staked in the clip


20


. To secure the keeper


40


to the front panel


14


, referring to

FIG. 4

, pins


42


extend from a plate


44


through the panel


14


(fabric) and are then staked in the keeper


40


.




Referring to FIGS.


4


and


5




a


, the keeper


40


is shown in greater detail and comprises a base


46


and side grooves


48




a


and


48




b


which define a ridge


50


having locking ribs


52


. The ridge


50


is characterized by locking teeth


54


having convex surfaces


56


.




Referring to FIGS.


4


and


5




b


, the snap


20


is shown in greater detail and comprises a top


28


having depending walls


30




a


and


30




b


terminating in inwardly extending locking teeth


32




a


and


32




b


. On the underside of the top


28


is a depending locating block


34


having two locking teeth


36


, having convex surfaces


58


, which teeth


36


define a recess


38


. The block


34


is centered with reference to the walls


30




a


and


30




b


. Four protecting pillars


59


extend from the top


28


and terminate in surfaces which are coplanar wit the surfaces of the locking teeth


32


.




The clip


20


and keeper


40


comprise a button snap flap closure


60


shown in

FIGS. 6 and 7

. To secure the flap


18


to the front panel


14


, the clip


20


slides along the keeper


40


until the flap


18


feels secure or taunt. The clip


20


is then pressed into the keeper


40


. The convex surfaces


56


and


58


self-align the clip


20


and the keeper


40


. The locking teeth


32


of the clip


20


snap over the ribs


52


with the locking teeth


32


received in the side grooves


48


thereby locking the clip


20


to the keeper


40


.




The recess


38


of the clip


20


is engaged by a locking tooth


52


of the keeper


40


which prevents movement of the clip


20


along the axis of the keeper


40


.




The closure


60


of the invention accomplishes four things: 1) the clip


20


fixed to the pocket flap


18


can be attached anywhere along the length of the ribbed ridge


50


fixed to the outside of the pocket. The further down the clip


20


is attached to the ribbed ridge


50


, the tighter the pocket flap is drawn down over the pocket opening. 2) The high profile of the ribbed ridge


50


easily catches the opening on the clip


20


(ease of alignment on the y axis). 3) The length of the ribbed ridge


50


provides a large target for the clip


20


to engage (ease of alignment on the x axis). 4) The length and stiffness of the ribbed ridge


50


provides a stable base that keeps the mating ribs


52


of the ridge


50


and the clip


20


aligned as the clip is pressed into the locked position.




The foregoing description has been limited to a specific embodiment of the invention. It will be apparent, however, that variations and modifications can be made to the invention, with the attainment of some or all of the advantages of the invention. Therefore, it is the object of the appended claims to cover all such variations and modifications as come within the true spirit and scope of the invention.
