TECHNICAL FIELD

The instant invention relates to protective covers, particularly to a protective cover for an electronic remote control device.

BACKGROUND OF THE INVENTION

The remote control device has become a ubiquitous part of daily life, serving to control such diverse electronic equipment as televisions and various audio-visual devices. As a result, they tend to be handled by a wide range of persons, using a widely divergent level of care. The remote control device is thus both subject to damage, and likely to become a vector for passing potentially infective agents. This latter problem is particularly acute, as the electrical nature of these devices and their plurality of pushbuttons both act to make cleaning relatively difficult.

Various devices have attempted to deal with aspects of these problems, although none as reasonably and effectively as the instant invention.

First, the issue of damage must be considered from several aspects. A number of devices attempt to prevent impact damage, such as might occur in dropping the remote control device. A prototypical example is U.S. Pat. No. 5,931,434 to Rodriguez. The '434 device provides a peripheral collar type structure around a remote control device designed to resist impact. The utility of such a device is, however, dubious. To begin with, casual experience with remote controls devices will suggest to most users that the units are, in fact, quite resistant to impact damage on their own, and there is little benefit from additional padding. Additionally, such a unit does nothing to confront the main sort of damage a remote control unit is likely to encounter in the real world, the intrusion of dirt or liquids into the unit.

The problem of an electrical device exposed to dirt and liquid is addressed better in such devices as U.S. Pat. No. 5,499,713 to Huffer. The '713 device provides a closable envelope that surrounds a remote control device. However, while such an envelope may protect somewhat against dirt or liquid intrusion, or make the surface easier to clean, the device does little if anything to protect the user of such devices.

A remote control device, especially when found in the homes of large families, or in such multi-user environments as schools, hotels, or hospitals, is handled by a large number of people. Each of the persons who handle the remote control device imparts some level of contamination onto the surface of the device. Providing only an outside envelope, such as the '713 device, does no more than interpose another layer onto the exterior of the device. The potential for contagion is not particularly reduced, nor does the operator have any reliable indication as to the cleanliness state of the device.

Accordingly, the art has needed a means for improving the art of remote control covers. While some of the prior art devices attempted to improve the state of the art of remote control covers, none has achieved the unique and novel configurations and capabilities of the present invention. The present invention makes many improvements over the current state of the art. First, the enclosure is sealed while in use, preventing contamination from reaching the electronic controller. Second, the seal is permanent, making the enclosure tamper evident. Third, being formed of inexpensive materials, soiled covers can be easily stripped off and replaced. At least in some embodiments, the cover is formed from a material having antimicrobial surface qualities. With these capabilities taken into consideration, the instant invention addresses many of the shortcomings of the prior art and offers significant benefits heretofore unavailable. Further, none of the above inventions and patents, taken either singly or in combination, is seen to describe the instant invention as claimed.

SUMMARY OF INVENTION

In its most general configuration, the present invention advances the state of the art with a variety of new capabilities and overcomes many of the shortcomings of prior devices in new and novel ways. In its most general sense, the present invention overcomes the shortcomings and limitations of the prior art in any of a number of generally effective configurations. An object of this invention is to provide a flexible hygienic remote control enclosure for receiving and housing a wireless remote control device that prevents outside contaminants from reaching the wireless remote control device. Further objects of the invention include, providing a sealed, tamper evident enclosure. In some embodiments, the enclosure is formed from a material exhibiting antimicrobial properties, to reduce microbial growth on the surface of the enclosure

In various embodiments, the enclosure is formed having a bottom wall having a peripheral edge, at least one sidewall having at least an inner surface, an outer surface, a distal end, and a proximal end. The distal end is attached to the bottom wall peripheral edge to provide a substantially flat window at the bottom of the enclosure to facilitate the passage of signals from the remote control to the target device. The proximal end is initially open through which the wireless remote control device is inserted. After the remote control device is placed in the enclosure, a closure means permanently seals the wireless remote control device in the enclosure. This makes the enclosure tamper evident, as the enclosure must be stripped off of the remote controller for the controller to be accessed. The inexpensive nature of the instant invention makes frequent replacement economically feasible.

As needed for proper operation of the electronic device to be controlled, in those embodiments utilizing a substantially flat bottom wall, the bottom wall is transparent, at least in part. To allow viewing of the enclosed remote control, at least a portion of the at least one sidewall is transparent. The remainder of the sidewall may be affixed with sidewall indicia, such as, by way of example and not limitation, advertising, television channel information, and the like.

Various embodiments utilize different mechanisms to achieve a permanent seal for the enclosure, permanent meaning in this case a closure that is stronger than the material to which it is attached, and which therefore requires a breaking or tearing of the enclosure in order to release the remote controller. In a first class would be those which achieve a permanent adhesive seal. In one embodiment, closure means includes at least one adhesive securing strip, releasably covered with a removable protective strip, attached to the inner surface of the sidewall between the distal end and the proximal end. The removable protective strip may be removed from the adhesive strip, and the enclosure pressed shut over the adhesive. In another embodiment, the closure means includes a drawstring, which may be pulled tight, closing the opening to the enclosure, and at least one adhesive strip on the drawstring secures the proximal end to the enclosure in a closed position.

In yet another embodiment, the closure means includes a sealing flap having an inner and outer surface, having at least one flap adhesive securing strip on the inner surface, releasably covered with a removable protective strip, flexibly attached to the at least one sidewall outer surface. The drawstring may be pulled tight, closing the opening to the enclosure, the drawstring tucked under the sealing flap, and the sealing flap then sealed down to both contain the drawstring and to prevent opening of the enclosure. Similar to those embodiments where printed indicia is affixed on the sidewall of the enclosure, the use of a sealing flap allows the outer surface of the sealing flap to be affixed with indicia.

As an alternative to the use of permanent adhesives to seal the enclosure, a second class of permanent closure utilizes various mechanical means to seal the enclosure. In one embodiment, the closure means includes a locking mechanical closure arranged to crimp and permanently seal the enclosure.

It is envisioned that the enclosure will function well with a small amount of residual air trapped within the sealed enclosure, however, in one embodiment, at least one vacuum attachment device is attached to the at least one sidewall to remove fluid, by way of example and not limitation, entrapped air, from the enclosure. Removal of this entrapped air will tend to cause atmospheric pressure to collapse the enclosure around the remote controller, giving a tighter and more form fitting aspect to the enclosure in use.

In commercial applications, the enclosure may be sealed with a vacuum device and heat seal apparatus, such as might be carried on a housekeeper's cart. Additionally, sealing could be accomplished by various chemical processes, as would be understood by one skilled in the art. In all of the embodiments described herein, the enclosure may be supplied in a limited number of sizes and shapes. The various sealing mechanisms described allow some degree of customization to the size of the remote controller enclosed, and in various embodiments, excess enclosure material outside of the permanent closure may often be cut off and discarded.

The hygienic aspects of the enclosure are principally achieved by protecting the remote controller from direct contamination, improved ease of cleaning the smooth external surface of the enclosure, and the ease and inexpensive basis with which soiled enclosures may be stripped off and removed. However, in one embodiment, the at least one sidewall and the bottom wall include an antimicrobial agent, wherein the antimicrobial agent may form a surface coating and which may exhibit migration through the at least one sidewall and the bottom wall as the surface coating of antimicrobial agent is depleted.

As an alternative to the above embodiments utilizing a sidewall and bottom wall construction, the enclosure may be formed into a pouch with an open end to receive the controller. After the controller is placed within the pouch, the same closure means, including, but not limited to, adhesive, chemical, thermal, and mechanical, detailed in the embodiments described herein, may be used to permanently seal the enclosure. Similarly to the above, in the pouch style embodiment, at least one vacuum attachment device may be attached to the pouch to remove fluid from the enclosure, and the pouch may be formed of antimicrobial material.

In an alternative construction, the enclosure may be formed with at least one sidewall, wherein the inner surface of the sidewall is circumferentially attached to itself substantially at the distal end, forming a bottom wall. As with preceding embodiments, the proximal end is initially open through which the wireless remote control device is inserted, and a closure means permanently seals the wireless remote control device in the enclosure. The same variations in partial transparency, closure mechanisms, locations for imprinting of printed indicia, and antimicrobial qualities of the enclosure are possible, as with the preceding embodiments.

The instant invention enables a significant advance in the state of the art. The preferred embodiments of the apparatus accomplish this by new and novel arrangements of elements that are configured in unique and novel ways and which demonstrate previously unavailable but preferred and desirable capabilities.

It is to be understood, however, that the same or equivalent functions and features may be accomplished by different embodiments that are also intended to be encompassed within the spirit and scope of the invention.
