Description of the Preferred Embodiments
Referring now in detail to the various views of the drawings, there is shown in FIG. 1 a two-piece adjustable fastener or waistband assembly 10 of the present invention which is applied to a garment, such as a pair of trousers 12, in order to effect a ready adjustment in the waist dimension for accommodating the body of a wearer. The waistband assembly 10 is comprised of a track member 14 which is attached to an underlying part 12a of the trouser waistband 11 and a latch member 16 which is attached to an overlying part 12b of the trouser waistband 11. The track member 14 may be suitably sewed so as to be fixedly attached to the underlying part 12a of the waistband 11. The latch member 16 likewise may be suitably sewed so as to be fixedly attached to the overlying part 12b of the waistband. The latch member 16 is adapted for receiving the track member which is pushed into detachable interengagement with the latch member, whereby the latch member is releasably locked or latched at various positions along the track member.
In FIGS. 3-6 of the drawings, there are illustrated in the various views the details of the construction of the track member 14 of the waistband assembly 10. The track member 14 is formed of a central horizontal web portion 18 and spaced apart vertical side wall segments 20 and 22 disposed upon opposite sides of the web portion 18 and extending between the ends 24, 26 thereof. At the upper ends of the side wall segments 20 and 22, there are provided outwardly extending flanges 28, 30 which are disposed perpendicularly to their respective side walls 20, 22. Between the adjacent side wall segments 20 directly above the web portion within its one side, there are formed a series of openings 32. Similarly, there are formed a series of openings 34 between the adjacent side wall segments 22 within the other side of the web. Each of the openings 34 of the one side are arranged in alignment with the respective openings 32 on the opposite side so as to form a plurality of substantially rectangularly-shaped slots or recesses 36.
As can best be seen from FIG. 4, the lower outer surface of the web portion 18 is formed with U-shaped cutouts 38 so as to provide flexibility in the track member 14. In FIG. 6, a stop member 40 is disposed at the right end 26 of the web portion 18 for a purpose to be presently explained. The track member 14 may be formed of a high or low density polyethylene, polypropylene, or other resilient plastic material and can be fabricated by means of insert injection molding techniques as a single-piece. The web portion 18 is designed to be thin enough so as to be sewed to the underlying part 12a of the waistband 11. Alternatively, the web portion 18 may be provided with pin holes (not shown) so as to facilitate sewing. Furthermore, the track member 14 is designed to be flexible enough so as to be bendable about the waist of the wearer during use.
In FIGS. 7-9 of the drawings, there are illustrated in the various views the details of the construction of the latch member 16 of the fastener assembly 10. The latch member 16 has a substantially rectangular configuration having an outer rim portion 42 and an intermediate portion 44 disposed centrally within the rim portion 42 so as to define elongated slots 46a, 46b therebetween. The outer rim portion 42 is made so as to be sloped downwardly from its outer edge 48 towards the intermediate portion 44. Likewise, the latch member 16 may be formed of a high or low density polyethylene, polypropylene, or other resilient plastic material and can be fabricated by means of insert injection molding techniques as a single-piece. The outer rim portion 42 is designed to be thin enough so that it can be sewed along the dotted line 43 onto the inside surface of the overlying part 12b of the trouser waistband 11.
The intermediate portion 44 is comprised of a C-shaped base section 50 which is located between two sides of the outer rim portion 42 so as to form the elongated slots 46a, 46b therebetween. The base section 50 includes a pawl 52 having an inclined surface 54, a flat top surface 56 and a vertical surface 57. The pawl 52 is formed upon the surface of a flat member 59 of the base section 50. A pair of vertical wall members 58, 60 are integrally formed upon the flat member 59 upon opposite sides of the pawl 52 and extend longitudinally between the elongated slots 46a, 46b. At the uppermost extremities of the respective wall members 58, 60 adjacent the elongated slot 46b, there are provided corresponding depending or inwardly extending support legs 62, 64 which are spaced opposite each other so as to form an aperture 63 therebetween for purposes to be described hereinafter.
As can be seen from FIG. 2, the elongated slots 46a, 46b serve as a means for attaching the latch member 16 to a garment cover strip 66. The ends of the cover strip 66 are sewn to be underlying part 12a of the waistband adjacent the ends of the track member 14 so as to cover or conceal the track member. The track member 14 is slidable into the latch member 16, and the latch member is movable along the length of the track member 14 with the vertical wall members 58, 60 and the depending support legs 62, 64 serving as a guide to enable the flanges 28, 30 of the track member to slide along the surfaces of the vertical walls and depending legs. The web portion 18 is passed through the aperture 63 formed by means of the depending legs as the latch member is moved along the length of the track member.
As is depicted in FIG. 2a, the latch member 16 may be moved towards the right end of the track member 14 by pushing the latch member towards the right so as to cause the flanges 28, 30 to slide up the inclined surface 54 and have the pawl 52 of the latch member 16 sequentially engage with the recesses 36 defined within the track member 14, thereby detachably interengaging the latch member with the track member. It should be noted that the left end of the outer rim portion 42 adjacent the elongated slot 46a functions to provide a spring bias to exert a downward force causing the pawl 52 to be retained within one of the rectangularly-shaped recesses 36 and the vertical surface 57 of the pawl prevents movement of the latch member back toward the left end of the track member. Thus, the latch member 16 may in this way be adjusted to a desired latched position along the length of the track member 14. The movement of the latch member toward the right end of the track member is limited as a result of engagement of the stop member 40 against the outer surfaces of the legs 62, 64.
In order to move the latch member 16 towards the left end 24 of the track member 14, it is necessary to manually raise the left end of the latch member 16 in an upward direction which causes the latch member to pivot within the track member 14 about the legs 62,64 in a direction opposite the biasing direction whereby pawl 52 is engaged within a selective one of the recesses 36 so as to cause disengagement of the pawl 52 from the recess 36. As a result, the latch member 16 may now be held by means of one's fingers so as to slide the same along the flanges 28, 30 towards the left end 24 of the track member. When the left end of the latch member 16 is released, the pawl 52 will again become engaged with one of the recesses 36 so as to provide a latched position because of the resiliency or spring bias of the outer rim portion 42.
In FIGS. 10 and 11 of the drawings, there are shown a second embodiment of the present invention which is applied to a cap 67 and consists of a two-piece adjustable cap band assembly 68. The adjustable cap band assembly 68 is comprised of a track member 70 and a latch member 72. The track member is attached to a part 67a of the cap 67 by sewing or any other well-known means and is identical in construction to the track member 14 previously described. Thus, the details of the track member 70 will not be repeated.
The latch member 72 is provided with an elongated slot 74 for receiving and/or attachment to one end of a strap 76. The other end of the strap 76 may be sewed to a part 67b of the cap. The latch member 72 has a generally rectangular configuration having a first end 77 and a second end 79. The latch member 72 includes a pawl 78 formed adjacent its first end 77 which is engageable with one of the slots 36a defined within the track member 70. A single leg member 80 is formed integrally with the pawl 78 and extends longitudinally towards the second end 79 of the latch member. The first end 77 of the latch member 72 provides a spring bias so as to exert a downward force causing the pawl 78 to be retained within one of the slots 36a and to prevent disengagement of the latch member 72 from the track member 70 as was described with respect to the first embodiment.
In order to disengage the pawl 78 from the slot 36a so as to permit movement of the latch member along the track member, it is necessary to manually lift the left end 77 of the latch member 72 in the direction of the arrow A and then slide the same along the flanges of the track member.
In FIG. 12, there is illustrated a second embodiment of a track member 14aof the present invention. The track member 14a is substantially identical to the track member 14 of FIG. 4, except that the U-shaped cut-outs 38 have been replaced with apertures 82 formed within the central horizontal web portion 18a between the spaced apart side wall segments 20a, 22a disposed upon the opposite sides of the web portion. These apertures 82 serve to provide a greater resiliency or flexibility so as to facilitate bending of the track member 14a during use, thereby rendering an easier and smoother operation of the adjustment assembly.
From the foregoing detailed description, it can thus be seen that the present invention provides a two-piece adjustable fastener assembly for use upon a garment band which consists of a sewable track member attached to one part of the garment band and a sewable latch member attached to the other part of the garment band. Furthermore, the latch member is provided with a pawl which is resiliently biased into slots formed within the track member, thereby detachably interengaging the latch member with the track member. The track member and latch member may both be formed of a resilient plastic material so as to facilitate manufacture and assembly.
While there has been illustrated and described what is at present considered to be preferred embodiments of the present invention, it will be understood by those skilled in the art that various changes and modifications may be made, and equivalents may be substituted for elements thereof without departing from the true scope of the invention. In addition, many modifications may be made to adapt a particular situation or material to the teachings of the invention without departing from the central scope thereof. Therefore, it is intended that this invention not be limited to the particular embodiments disclosed as the best modes contemplated for carrying out the invention, but that the invention will include all embodiments falling within the scope of the appended claims.
