BRIEF DESCRIPTION OF THE DRAWINGS

[0013] These and other features of the invention will be more clearly understood from a consideration of the following description, taken in connection with the accompanying Drawings in which:

[0014] FIG. 1a is a front view of the plug of the sealing device of the invention (a rear view being a mirror image), FIG. 1b is a front perspective view, and FIGS. 1c and 1d are bottom and left side views respectively;

[0015] FIGS. 2a-2g are 7 views of a protective case for a digital video electronic camera/camcorder helpful in an understanding of the sealing device of the invention;

[0016] FIGS. 3a and 3b are top and perspective views, respectively, illustrating a portion of the digital video protective case helpful in an understanding of the connection of the sealing device open cup and the closure plug; and

[0017] FIGS. 4a- 4f are 6 views of a latch lock helpful in an understanding as to how the closure plug is firmly seated in the open cup of the sealing device when the back cover of the protective camera case is closed.

DETAILED DESCRIPTION OF THE INVENTION

[0018] As will be appreciated, FIGS. 2a-2g respectively illustrate a front view of the protective waterproof case of the invention, a top plan view, a bottom plan view, a right side elevation view, a left side elevation view, a rear elevation view, and a rear perspective view. Reference numerals 50 and 51 identify a clear lens cover and a surrounding lens cover frame for the case 55, reference numerals 52 and 54 represent pillar receptors to couple to various mounts and accessories for the case and for the digital video electronic camera/camcorder enclosed within, and reference numeral 56 represents a transparent back cover. Reference numeral 58 represents a latch member to lock and hold the back cover 56 closed, with its lip 62 bendable outward to allow the back cover 56 to be opened and closed. Reference numeral 64 represents the cup of the audio port for passing sound into the compartment which encloses the electronic camera/camcorder. The cup 64 is additionally shown in FIGS. 3a and 3b as open, passing audio internally of the case 55 by way of an audio port aperture 65 (FIG. 3b).

[0019] Referring to FIGS. 1a-1d, the sealing device of the invention 10 includes a component closure plug 12, an anchoring end 14 having an aperture 16, and a connecting stem 18. A screw or similar fastener 30 extends through the aperture 16 and back cover 56 (FIG. 2e) in securing the sealing device 10 to the protective case 55 (as at A in FIGS. 3a and 3b). The closure plug 12 (preferably of silicone) is sized and configured to seat and snugly fit into the open cup 64 of the audio port entry, shown at B in FIGS. 3a and 3b. Inserting the closure plug 12 (in accordance with this first embodiment of the sealing device of the invention) effectively seals off the audio port entry in a waterproof manner, without allowing the entry of sound to reach the electronic camera/camcorder's built-in internal microphone. This would be the situation when sound is not generally relevantas in the underwater activities of snorkeling, spear fishing and scuba diving.

[0020] With this first version of the sealing device, therefore, waterproofing of the protective case is provided for underwater activity and sound does not enter the audio port entry when the closure plug is seated into the open cup. With the closure plug removed for air and land activity, sound enters the case to the internal microphone via the opened audio port entry.

[0021] Recognizing that a user might forget to insert the closure plug 12 for underwater activities, the second embodiment of the sealing device of the invention provides its own protection thereby including a thin waterproof acoustic membrane within, but spanning across the open cup of the audio port entry to vibrate in allowing the entry of sound wave pressures from an outside environment, but not water, into the electronic camera/camcorder protective case. Such embodiment will be understood also useful where the photographic activity is more in the nature of swimming, surfing, kayaking and white water rafting where waterproofing is desired along with some degree of sound accompaniment of the activity. As will be appreciated, however, this construction of the audio port entry is less desirable in sound reproduction for air and land usage than with the first embodiment of the sealing device where the closure plug 12 is simply withdrawn from the open cup 64 for best sound recording.

[0022] To further prevent the closure plug 12 dangling about when withdrawn from the open cup 64 for air and land use, the closure plug 12 is provided with a small magnetic tip 20 (FIGS. 1b and 1c) to join with a screw fastener in being held in place thereby. As illustrated in the protective case side views of FIGS. 2d and 2e and in the perspective view of FIG. 2g, and via the profile views of the latch member 58 in FIGS. 4a-4f, closing the latch member 58 to lock the back cover 56 is in a direction to urge the closure plug 12 into the open cup 64 in securing the closure plug 12 into position within the audio port entryto not only enforce the waterproof seal that results, but to additionally act in a direction to prevent the closure plug 12 from accidently popping out. The screw fastening to the case in this respect is shown at 30 in FIGS. 2e, 2f and 2g. The logo 33 in FIGS. 2f and 2g merely represents a display on the screen of the enclosed digital video camera.

[0023] While what have been described are considered to be preferred embodiments of the present invention, it will be readily appreciated by those skilled in the art that modifications can be made without departing from the scope of the teachings herein. For at least such reason, therefore, resort should be had to the appended claims for a true understanding of the invention.
