DETAILED DESCRIPTION OF THE INVENTION

[0028] Referring to FIGS. 1-14, one embodiment of the detachable hinge assembly 10 of the present invention is illustrated. In one embodiment, the detachable hinge assembly 10 is employed on a cooler 50. However, the hinge 10 is not restricted to use with a cooler 50; and, in fact, can be employed anywhere a quick-release detachable hinge is useful.

[0029] As shown in FIGS. 1-8 and 13, a cooler 50 has a body 52 connected to a lid 54 through a detachable hinge assembly 10. The cooler body 52 has a perimeter sidewall 56 and a bottom wall 58. The perimeter sidewall 56 extends from the bottom wall 58 to an upper rim 60, which forms an opening into the body of the cooler 50. The cooler lid 54 engages the upper rim 60 to seal the cooler 50. The cooler lid 54 is removably attached to the cooler 50 through the detachable hinge assembly 10. The cooler 50 can also include an inner receptacle 62, such as a liner, to help insulate articles placed inside of the cooler 50.

[0030] The detachable hinge assembly 10 includes a first attachment bar 14 coupled to the cooler 50 and a second attachment bar 12 coupled to the cooler lid 54. As shown in the embodiment illustrated in FIGS. 1-14 the first attachment bar 14 is formed as part of the upper rim 60; however, in alternate embodiments, the attachment bar 14 can be a separate piece that is coupled to the rim 60. Also shown in this embodiment is the second attachment bar 12, which is formed integrally with the coolerlid 54 on a perimeter of the lid 54; but again, in alternate embodiments, the attachment bar 12 can be a separate piece that is coupled to the perimeter of the lid 54. The first attachment bar 14 has a first end 33 and a second end 34. The second attachment bar 12 has a first end 35 and a second end 36.

[0031] The detachable hinge assembly 10 allows the lid 54 to be pivotably coupled to the cooler body 52 through the first attachment bar 14 and second attachment bar 12. The first attachment bar 14 is coupled to the second attachment bar 12 through a first hinge member 16 and a second hinge member 18. As shown in the figures, in a preferred embodiment, the first and second hinge members 16, 18 can be constructed the same to reduce the number of unique pieces required for the construction.

[0032] FIGS. 9-12 illustrate a preferred embodiment of the hinge member 17, which can be used as both the first hinge member 16 and the second hinge member 18. As shown, the hinge member 17 includes an end flange 20 and an attachment projection 22 extending from the inner surface of the end flange 20. The projection 22 is designed to releasably couple to a corresponding projection 22 on a second hinge member 17. The projection 22 includes an insertion clip 24 and a receiving portion 26, where the snap or ramp lock 24 is on one half of the projection 22 and the receiving portion 26 is on a second half of the projection 22. When two hinge members 17 engage with each other, the insertion clip 24 of the first projection 22 inserts into the receiving portion 26 of the second hinge member 17, and vice versa, allowing the snap locks to releasably engage a catch 27 integrally formed on the projection.

[0033] The hinge member 17 also includes a first attachment region 30 and a second attachment region 28 on the end flange 20. The first and second attachment regions 30, 28 are constructed to be able to pivotably couple to the first and second attachment bars 14, 12, respectively. In the hinge member shown in FIGS. 9-12, the first attachment region 30 includes an attachment pin 31, such as an axle, stub shaft or other generally cylindrical projection, to pivotably couple with a corresponding attachment aperture recess 15 located at the distal ends of the first attachment bar 14, as shown in FIG. 13, and the second attachment region 28 includes a generally cylindrical aperture 29 to pivotably couple with a corresponding attachment shaft 13, such as an axle, on the second attachment bar 12. In these embodiments, generally cylindrical refers to any shape that would allow rotation of the attachment bars with respect to the hinge.

[0034] It should be noted, however, that the first and second attachment regions 30, 28 can include an attachment rod or an aperture, so long as the first and second attachment bars 14, 12 include the corresponding structure to allow the first and second attachment regions 30, 28 to pivotably couple to the first and second attachment bars 14, 12. For example, the first and second attachment regions 30, 28 could each include an attachment portion, such as an axle, so long as both the first attachment bar 14 and second attachment bar 12 included an attachment aperture recess 15 at the end. Conversely, the first and second attachment regions 30, 28 could both include an aperture to connect to attachment axles on the ends of the first and second attachment bars 14, 12. The hinge assembly 10 could also include any combination thereof between the hinge member 17 and the attachment bars 14, 12. It should also be noted that the present device allows, although does not require, each attachment bar to be formed as a single piece through the process of injection molding, or the like, to minimize components of the assembly.
