BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates, in general, to cases or enclosures and, more particularly, to cases for receiving portable electronic apparatus having manipulatable exterior pushbuttons or switches.

2. Description of the Art

The average person typically uses one or more portable electronic devices on a daily basis. Such devices include pagers, cellular telephones, remote vehicle keyless entry transmitters, hand-held tape recorders, etc. All such portable electronic devices are characterized by a hard plastic case containing internal circuits and mechanisms for operating the particular device. Pushbuttons or other activating means are typically mounted on one or more exterior surfaces of the housing for providing user selection of input functions to operate the device. Certain of these devices, such as cellular telephones and pagers have a visual LCD or LED display for displaying messages and other alphanumeric information. A handheld, portable tape recorder has a pivotal tape receiver for receiving and expelling tape.

All such devices also include a snap-in or pivotal cover allowing access to storage batteries for replacement of the batteries as needed.

Cases formed of leather, vinyl, fabric, etc., have been constructed to cover such portable electric devices and provide a measure of protection to the rather delicate circuits contained in such devices. Such cases are usually provided in only a few colors which may not always provide an attractive appearance or match the surroundings in which such devices are used, such as a vehicle interior, a home or office, etc. The following detailed description of one such electronic device and the problems associated with the construction of a case for the device will be understood to apply equally to all types of small, portable electronic devices, such as those described above.

Remote keyless entry transmitters are a popular option for current vehicles as they enable the vehicle driver to unlock and/or lock the vehicle doors while the driver is outside of the vehicle. Typically, a small housing having dimensions of approximately 1″ square×¼ thick contains transmitter circuitry and a small battery power source. Several pushbuttons are mounted on one side of the housing for separate door lock and door unlock operations. Additional vehicle functions may also be controlled by separate pushbuttons provided on the housing, such as a trunk release pushbutton and a vehicle horn or alarm pushbutton.

Depression of any pushbutton when the driver is located a short distance from the vehicle causes the transmitter to transmit a radio frequency coded signal to a receiver mounted within the vehicle. The receiver decodes the signal and activates the appropriate vehicle operating circuit to lock or unlock the doors, release the trunk lock and/or activate the vehicle horn.

The housing has an aperture at one end which receives a key ring or enables the housing and the entire remote keyless transmitter device to be mounted on the driver's key ring.

However, in interests of economy, the transmitter housing is typically provided in only one or two non-descript colors, such as black or other neutral colors, such as gray, etc. These colors do not always match the color of the interior vehicle trim in which the transmitter is used. This can cause an unsightly appearance when the transmitter housing hangs from the key ring and the ignition key is in the vehicle ignition. This unsightly appearance is also inappropriate with the lush, expensive interiors frequently found on more expensive luxury vehicles.

Further, during handling of the transmitter, such as the driver's act of putting his or her key ring carrying the remote keyless transmitter into and out of his or her pocket or purse, it is common for one of the transmitter pushbuttons to be inadvertently depressed. This could cause an unwanted operation of one of the vehicle circuits to inadvertently lock or unlock the vehicle doors, open the vehicle trunk and/or activate the vehicle horn.

Thus, it would be desirable to provide an enclosure or case for a portable electronic apparatus which provides both decorative and protective functions and which can be made from a variety of materials and colors to provide an aesthetic appearance consistent with the expense or luxury level of the surroundings in which the apparatus is used or the luxurious appearance the user wishes to portray. It would also be desirable to provide an enclosure for a portable electronic apparatus which enables the pushbuttons on the apparatus to be manipulated when the apparatus is in the case.

SUMMARY OF THE INVENTION

The present invention is an enclosure or case, which receives and protects a portable electronic apparatus, such as a remote vehicle keyless transmitter, electronic pager, etc., while still allowing manipulation of the electronic device external pushbuttons through the case.

In one aspect of the present invention, the case includes exterior walls defining an interior cavity for receiving an electronic device and pushbutton indicating means carried on at least one exterior wall and substantially alignable with a pushbutton on the electronic device when the electronic device is mounted within the interior cavity of the case for indicating the position of the pushbutton and allowing actuation of the pushbutton through the exterior wall of the case.

In a specific aspect, the present invention defines a case in the form of an enclosure having a front wall, a rear wall, bottom wall, opposed side walls, an open top end and a closeable flap to define an interior chamber sized to releasibly receive a portable electronic apparatus. Preferably, the flap is formed as an extension of one of the front and rear wall of the case and is foldable over the opposed case wall and releasibly joined thereto by means of suitable fasteners, such as snap fasteners, hook and loop fasteners, etc.

The indicating means is provided on one or more walls of the case to align with and to indicate both the position and, preferably, the function of the pushbuttons on the electronic apparatus when the apparatus is mounted within the case. The indication means may be provided by a variety of processes, including embossing, various printing methods and combinations thereof.

According to another aspect of the present invention, an aperture is formed in the flap permitting attachment of the electronic device to a key or key ring through the aperture.

The case is formed of any of a variety of flexible materials to provide an aesthetic appearance for the electronic apparatus. Exotic animal hides or skins may be employed as well as other luxurious materials to provide a luxurious appearance for the case.

Aside from the aforementioned aesthetic appearance feature, the case of the present invention also has a protective function in that the case covers the depressible pushbuttons of the electronic apparatus to prevent inadvertent depression of any of the pushbuttons during handling of the electronic apparatus.

The unique case of the present invention provides both a protective and decorative appearance for a portable electronic device, such as a remote vehicle keyless transmitter, electronic pager, etc. The case may be formed of any suitable material to provide a luxurious appearance as well as possible color match to a vehicle interior. At the same time, the case provides an indication of the location of the pushbuttons on the interior mounted electronic device and allows manipulation of the pushbuttons due to the flexible nature of the exterior walls of the case. This not only permits the interior mounted electronic device to be utilized in a normal fashion; but, at the same time, minimizes inadvertent actuation of one of the pushbuttons as would typically occur when the case and the electronic device are handled during insertion of or removal from a user's pocket, purse, etc., or thrown onto a table, desk, etc.
