DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

(15) Referring now in detail to the drawings, FIGS. 1-3 show a first embodiment of the system 10 according to the invention. System 10 consists of an attachment portion 20 and an operating portion 30, which are configured to be attached and detached from each other with a simple action. Attachment portion 20 has a base body 21 formed from a front wall 22 and a rear wall 23, with a cavity 218 between the front wall 22 and rear wall 23. A transverse bar 24 is connected to base body 21 and separated by a gap in which a second transverse bar 25 is located. Transverse bar 25 is separated by a slot to allow for webbing attachment during use. Two prongs 28, 29 extend down from base body within cavity 218. As shown in the cross-section in FIG. 8, locking hooks 201, 202 extend from base body 21 within cavity 218, on either side of prongs 28, 29. In an alternative embodiment, these prongs can be eliminated. Locking hooks 201, 202 face each other.

(16) Operating portion 30 is in the form of a D-ring and is formed from two side legs 31, 32, which are each connected to an inwardly extending top section 33, 34, respectively. Top sections 33, 34, are separated by a gap 38. Top section 33 has a locking hook 35 extending upward therefrom, and top section 34 has another locking hook 36 extending therefrom. The locking hooks 35, 36 each face outward, away from the gap. The operating portion 30 is constructed of a pliable material, so that pressing legs 31, 32, together causes the gap to narrow and the locking hooks 35, 36, to move toward each other. The rear wall of the attachment portion 20 has apertures 26, 27 therein so that the locking hooks 35, 36 of the operating portion 30 are visible through the apertures 26, 27 when the operating portion 30 is connected to the attachment portion 20.

(17) FIG. 3 shows attachment portion 20 and operating portion 30 connected to each other, the details of which will be explained below with reference to FIG. 8. The system 10 according to the invention is configured so that the operating portion 30 can be connected to a strap 40, as shown in FIGS. 4-7, in a secure and reliable manner, yet be easily detachable from attachment portion 20. To assemble the system, strap 40 is first sewn in a loop that serves as a rigid point for attachment bar 25 to attach attachment portion 20 within the loop, as shown in FIG. 6. The closed end of the loop is not shown, as it can be located at any distance from attachment portion 20. As the attachment bar 25 is a transverse bar separated by a gap, the two ends of the loop of strap 40 can enter the attachment bar 25 through the gap. When attached, attachment portion 20 is securely held in place inside the loop of strap 40. It can be undone and reused within the other loops of strap 40 or any other strap.

(18) Then, operating portion 30 is connected to attachment portion 20 with strap 40 already attached, by inserting locking hooks 35, 36 into cavity 218 until locking hooks 35, 36 engage locking hooks 201, 202 on attachment portion 20, as shown in the cross-section in FIG. 8. During assembly, strap 40 is placed between top sections 33, 34, which then extend into the loop on either side of strap 40, and hooks 35, 36 are then attached to attachment portion 20 within the loop of strap 40, so that strap 40 now wraps around the underside of top sections 33, 34 of operating portion 30, such as shown in FIGS. 5-7.

(19) Upward tension on strap 40 away from operating portion 30 presses operating portion 30 toward attachment portion 20, preventing any chance of separation. As the tension increases, either by increased tension on strap 40, or by tension from a strap attached to the bottom of operating portion 30, legs 31, 32 and top sections 33, 34 are deformed, which presses hooks 35, 36 even more tightly into engagement with hooks 201,202 within attachment portion 20, by the pressure of strap 40. Thus, the tighter the tension on strap 40, the more secure the connection between operating portion 30 and attachment portion 20. To detach operating portion 30 from attachment portion 20, the tension on strap 40 is slackened to create room for movement, and the user presses legs 31, 32 toward each other until locking hooks 35, 36 clear locking hooks 201, 202, at which point operating portion 30 can be disengaged from strap 40 through gap 38.

(20) Another embodiment of the attachment system is shown in FIGS. 9-11. Here, instead of a D-ring, operating portion 50 is a female part of a two-piece side-release buckle. Operating portion 50 comprises a female buckle body 58 having two side openings 501, 502 for receiving side legs 62, 63 of a corresponding male buckle body 60. Female buckle body 58 has two side legs 51, 52, arranged on the opposite side of female buckle body 58 from the main opening 59 which receives male buckle body 60. Side legs 51, 52 are connected to top sections 53, 54, which are separated by a gap 580. Each top section 53, 54, is equipped with a locking hook 55,56, which interact with corresponding locking hooks on attachment portion 20 in the same way as described with respect to FIG. 8. Attachment portion 20 shown here is identical to attachment portion 20 from FIGS. 1-8.

(21) Strap 40 is connected to attachment portion 20 in the same manner as described with respect to FIG. 4, and then operating portion 50 is connected to attachment portion 20 to connect the system together, with strap 40 extending around and underneath top sections 53, 54 of operating portion 50, as shown in FIG. 11. A second strap 70 can be connected to male buckle body 60, so that the system can connect two straps 40, 70 together in a simple and secure fashion. Instead of a D-ring or side-release buckle, operating portion 30, 50 can take on any suitable structure, such as a swivel hook buckle, a swivel square ring, a press release buckle male part, a press release buckle female part, a magnetic auto-connecting buckle male part, a magnetic auto-connecting buckle female part, a ladder buckle, a tri-glide buckle, a snap button, an O-ring, a square ring, a triangular ring, a snap hook, or a rope adjusting buckle. It can also be any electronic device: a light-emitting device, a video screen, a telephone, a remote contact tool, a video camera, a video recorder, a microphone, an amplifier, a fan cooler, a fan heater, an insulation device, a portable power source, an electronic protective case, a tension meter, etc. The operating portion 50 can be interchanged with fixed attachment portion 20 so that different elements can be easily connected and disconnected from strap 40, without removing attachment portion 20. Side legs 51, 52 can be equipped with ridges 504 (see FIG. 9) to assist a user in gripping the operating portion 50.

(22) Another alternative embodiment is shown in FIG. 12, which shows attachment portion 20 and operating portion 50 in a Molle system for use on a tactical vest or other item. Here, attachment portion 20 is connected to strap 40 in the same way as described above with respect to FIGS. 9-11. However, instead of strap 40 being sewn into a loop, strap 40 is sewn along attachment lines 47, 48 onto a substrate 80, which can be any type of flat sewable structure, such as a tactical vest. In use, strap 40 is first sewn in place and then attachment portion 20 is connected by fitting attachment bar 25 around strap 40, which places attachment portion 20 underneath strap 40. Then, operating portion 50 can be connected to attachment portion 20 in the same manner described above with respect to FIGS. 9-11. The flexible nature of the fabric of substrate 80 can be used to provide extra slack in the space between strap 40 and substrate 80 during assembly and disassembly of operating portion 50 with attachment portion 20. In use after assembly, the substrate is stretched flat so that there is little slack between attachment lines 47, 48. Tension on operating portion 50 by pulling strap 70 connected to male buckle body 60 only presses operating portion 50 more strongly against attachment portion 20, due to the pressure on operating portion 50 by attachment line 48.

(23) Accordingly, while only a few embodiments of the present invention have been shown and described, it is obvious that many changes and modifications may be made thereunto without departing from the spirit and scope of the invention.
