[0024] Referring now to the drawings, wherein the showings are for purposes of illustrating the present invention and not for purposes of limiting the same, FIGS. 1-4 show a fastener system 10 in accordance with a preferred embodiment of the present invention.

[0025] As shown in FIGS. 1 and 2, in a preferred embodiment, the fastener system 10 generally includes a female fastener assembly 12 and a male fastener assembly 36. The female fastener assembly 12 includes a housing 14 and a switch member 22, and the male fastener assembly 36 includes a post 38 having a slot 40 defined therein. The housing 14 has an upper surface 16 and a lower surface 18.

[0026] FIG. 2 is an exploded perspective view of a preferred embodiment of the fastener system 10. As shown in FIG. 2, in a preferred embodiment, the housing 14 has a channel 20 defined therein and a lower opening 30 defined therein that extends through the lower surface 18 and is in communication with the channel 20. The housing 14 also preferably includes an upper opening 31 that extends through the upper surface 16. Further as shown in FIG. 2, in a preferred embodiment, the female fastener assembly 12 includes the switch member 22, which includes a switch portion 28, a neck portion 23 and a receiver portion 24. In a preferred embodiment, the receiver portion 24 has a post opening 26 defined therein. In a preferred embodiment, the post opening 26 includes a fastening portion 32 and a removing portion 34. In a preferred embodiment, the switch member 22 is movable or slidable within the channel 20. The switch portion 28 includes an engagement portion 25 in a preferred embodiment.

[0027] In a preferred embodiment, the post 38 is cylindrical and includes the slot 40 extending circumferentially therearound. In another embodiment, the slot 40 may only extend partially around the post 38. In another embodiment, the post 38 can be another shape, such as square or rectangular and the slot 40 can be a notch. As described below, the slot 40 captures a portion of the receiver portion 24, when the switch member 22 is moved to the fastening position.

[0028] In a preferred embodiment of the present invention, as shown in FIGS. 2 and 3, the post 38 may have an inclined surface 37 and the lower opening 30 may be a self-aligning opening that includes an inclined surface 39 that cooperates with inclined surface 37, such that even if the post 38 is not inserted directly into the center of the lower opening 30, the inclined surface 29 will guide the post 38 into the lower opening 30.

[0029] FIGS. 3A and 3B show a preferred embodiment in which the fastener system 10 is used to join a first panel 42 and a second panel 44. In a preferred embodiment, the female fastener assembly 12 is secured to the first panel 42 and the male fastener assembly 36 is secured to the second panel 44. Any method for securing the female fastener assembly 12 to the first panel 42 and the male fastener assembly 36 to the second panel 44 is within the scope of the present invention. For example, glue, adhesive, welding, threaded fasteners, rivets or the like can be used. As shown in the drawings, in a preferred embodiment, the female fastener assembly 12 includes inserts 50 extending outwardly from the housing 14. The male fastener assembly 36 also includes an insert 50 extending therefrom. The inserts 50 are inserted into openings 54 defined in the first and second panels 42 and 44 and are adhered or potted therein. The inserts 50 can include lower flanges 52 thereon that help secure the inserts 50 within the openings 54. The inserts 50 can also include a middle or upper flange 56.

[0030] FIG. 3B shows a preferred embodiment of the fastener system 10 in the removing position. As shown in FIG. 3B, in a preferred embodiment, when the switch member 22 is in the removing position, the post 38 of the male fastener assembly 36 can be freely inserted through the lower opening 30 of the housing 14 and through the removing portion 34 of the post opening 26 of the switch member 22 (and through the upper opening 31). When the switch member 22 is in the removing position, the post 38 of the male fastener assembly 36 can be freely disengaged from the female fastener assembly 12 by removing the post 38 from the removing portion 34 of the post opening 26 of the switch member 22 and the lower opening 30 of the housing 14. As shown in FIG. 3B, in a preferred embodiment, when the switch member 22 is in the removing position, the slot 40 of the post 38 does not receive any portion of the receiver portion 24 of the switch member 22. The switch member 22 moves within the channel 20 of the housing 14. The use of a preferred embodiment to join panels as shown in FIGS. 3A and 3B and as described in this specification is merely exemplary. Those of ordinary skill in the art will appreciate that the fastener system 10 can be used to join items other than panels, including walls, partitions, monuments, shelves, and other items.

[0031] FIG. 3A shows a preferred embodiment of the fastener system 10 in the fastening position. As shown in FIG. 3A, in a preferred embodiment, when the switch member 22 is in the fastening position, the post 38 of the male fastener assembly 36 extends through the lower opening 30 of the housing 14 and through the post opening 26 of the switch member 22. The slot 40 of the post 38 is aligned with the channel 20 and receives a portion of the receiver portion 24 of the switch member 22, thus preventing the post 38 from being removed from the post opening 26. In other words, the fastening portion 32 of the post opening 26 has a smaller width or diameter than the post 38. Therefore, a portion of the receiver portion 24 is captured in the slot 40. This prevents the post 38 from being pulled through lower opening 30, thus securing the post 38 within the female fastener assembly 12. It will be appreciated that in the removing position, the removing portion 34 of the post opening 26 is aligned with the post 38 and in the fastening position, the fastening portion 32 of the post opening 26 is aligned with the post. And, in the fastening position, the slot 40 creates a ledge that captures the edge of the fastening portion 32 and prevents the post 38 from being pulled out of the housing 14.

[0032] As shown by arrow A1 in FIG. 3A, in a preferred embodiment of the present invention, the switch portion 28 is spring biased upwardly. As shown in FIG. 2, the switch portion includes a shaft 46 that extends beyond at least one side thereof. Preferably, the shaft 46 extends through an opening 47 in the switch portion 28 and extends outwardly from both sides thereof. In a preferred embodiment, the housing 14 also includes at least one and preferably two slots 48 defined therein that is in communication with the channel 20. As a result of the spring portion 38 being biased upwardly from the receiver portion 24, the opposite ends of the shaft 46 are received in and captured by the slots 48 when the switch member 22 is in the fastening position. Those of ordinary skill in the art will appreciate that the use of an upwardly spring-biased switch portion 28 in conjunction with a slot 48 in the housing 14 is merely exemplary and that other methods of securing the switch member 22 in the fastening position may be used in accordance with the present invention. By way of non-limiting example, a spring could be used within the channel 20 that exerts a horizontal force on the switch member 22, or adhesives could be used to hold the switch member 22 in the fastening position.

[0033] FIG. 4 shows an end elevational view of a preferred embodiment of the present invention as viewed from the end of the switch member 22. FIG. 4 shows a preferred embodiment in which the switch portion 28 of the switch member 22 protrudes beyond the upper surface 16 of the housing 14.

[0034] An exemplary use of the fastening system 10 will now be described. The female fastener assembly 12 is secured to a first panel 42 and the male fastener assembly 14 is secured to a second panel. The switch member 22 is positioned in the removing position and the post 38 is inserted through the opening 54 in the first panel 42, through lower opening 30 and through the receiving portion 34 of the post opening 26. The switch member 22 (and shaft 46) are then moved within the channel 20 to the fastening position. Because the switch portion 28 is biased upwardly, when the opposite ends of the shaft 46 reach the slots 48, the opposite ends of the shaft 46 are forced into the slots 48, thereby securing the switch member 22 in the fastening position. The fastening portion 32 of the post opening is simultaneously aligned with the post 38 and a portion of the receiver portion 24 is received in slot 40.

[0035] To disengage or remove the two panels from one another, the switch portion 28 is pushed downwardly so that the opposite ends of the shaft 46 come out of slots 48 and inwardly so that the opposite ends of the shaft 46 slide along channel 20 (as shown in FIG. 4) until the switch portion 28 is in the removing position. In this position, the receiving portion 34 of the post opening 26 is aligned with the post 38. This allows the post 38 to be pulled out of the post opening 26, the lower opening 30 and the opening 54 in the first panel 42.
