## Abstract

A protective enclosure for a portable electronic radio or "boom box" includes a heavy base having legs extendible from the base so that the electronic device can be supported above the ground surface. An external battery compartment is provided in the enclosure for external batteries which are connected to a connector mounted in the internal battery compartment of the electronic device. The connector takes the place of the batteries mounted in the battery compartment. This permits batteries to be manipulated as required without the necessity of removing the electronic device from the enclosure.

## Background
1. Field of the Invention

The present invention relates to protective enclosures for portable stereos. Such devices are protected from sand and weather with an enclosure having a heavy plastic base for the bag with legs, extendible from the base to support the radio above the sand or the ground. The stereo can be attached to the base and wrap around each end of the stereo. Compartments can be provided in the enclosure for batteries, CD's, tapes, etc. The invention proposes to use an external battery in a compartment formed in the bag. A connector is used to connect the external battery to the battery compartment of the stereo. The connector is a spring loaded device which has conductive points attaching to the existing battery terminals in the compartment. A wire connects the terminals to a connector which is coupled to the external battery.

There is a need for a protective enclosure for electronic devices such as portable radio/CD players when same are used at the beach or otherwise outside the home. One of the characteristics of such an enclosure is the ability to keep the radio/CD player in the enclosure on a permanent basis to that the inconvenience of inserting the device in the enclosure and removing same from the enclosure may be eliminated. The present invention is designed to provide such an enclosure.

The invention includes a heavy base having legs extendible from the base so that the electronic device can be supported above the ground surface. An external battery compartment is provided in the enclosure for external batteries which are connected to a connector mounted in the internal battery compartment of the electronic device. The connector takes the place of the batteries mounted in the battery compartment. This permits batteries to be manipulated as required without the necessity of removing the electronic device from the enclosure.

A principal object of the present invention is the provision of a protective enclosure for portable stereo radios, "boom" boxes, compact disc players and the like Another object and advantage of the invention is the provision of a protective enclosure in the form of a carrying bag for the electronic device. A still further object and advantage of the invention is-the provision of a carrying bag of the class described which can permanently house the electronic device. A still further object and advantage of the invention is the provision of a protective enclosure for an electronic device which does not require that the device be removed from the enclosures. Another object and advantage of the invention is the provision of a protective enclosure having a supporting base for the electronic device. A still further object and advantage of the invention is the provision of a protective enclosure where the supporting base has extendible legs to support the base and the device a desired distance above the surface on which the device is placed. A still further object and advantage of the invention is the provision of a protective enclosure having an external battery compartment formed in the enclosure. A still further object and advantage of the invention is the provision of a connector to connect the external battery in the battery compartment to the battery terminals of the electronic device. Another object and advantage of the invention is the provision of a battery connector having connections which attach to the battery terminals of the electronic device. Another object and advantage of the present invention is the provision of a battery connector which is spring loaded to fit within the battery compartment of the electronic device and to provide connectors from the battery compartment to the external battery.

These as well as further objects and advantages of the invention will become apparent to those skilled in the art from a review of the following detailed description of my invention, reference being made to the accompanying drawings in which:

FIG. 1 is a front view of the preferred embodiment of my invention;

FIG. 2 is a front view of a portion of the embodiment of my invention shown in FIG. 1;

FIG. 3 is a top view of the portion of the embodiment of my invention shown in FIG. 2;

FIG. 4-5 are diagrammatic views of an attachment used with the embodiment of my invention shown in FIGS. 1-3.

With reference to the embodiment of the invention shown in FIGS. 1-3, a portable stereo popularly known as a "boom box" 10 is inserted into a protective enclosure 1. The enclosure 1 includes a solid base 13 to which are attached two pairs of legs. A first pair of legs (one of which is shown at hinge 19 and leg 23) is foldable downwards from the position shown in FIG. 1 to the position shown in FIG. 2. A second pair of legs (one of which is shown at hinge 21 and leg 25) is also foldable downwards to the position shown in FIG. 1. In the FIG. 2 position, the legs serve to support the enclosure 1 and its contents a distance above the surface.

The bag 1 has two side compartments which are accessed by closures 9 and 11. The bag also has a top cover 3 which can be closed by closure 43 in FIG. 3. The bag also has a front cover 13 which can be closed by a closure 15. Strap 5 may be fastened to securing rings 7, 7' to support the bag and the radio on the shoulder.

As best shown in FIG. 2, the bag 1 has a second thin protective cloth 27 covering the face of the radio 10. The cloth 27 permits the cover 17 to be open so that the radio can be used. The cloth 27 protects the radio while the cover 17 is open without otherwise affecting the audio quality of the radio.

As best shown in FIG. 3, the supporting base 13 has four slots 33, 37, 39 and 41 formed therein. These slots receive a portion of straps 29 (in slots 33 and 41) and 31 (in slots 37 and 39). Straps 29 and 31 serve to hold the radio 10 onto the base 13. The slots are elongated to as to permit the straps to be used with radios of different dimensions.

Also shown in FIG. 3 is the rechargeable battery compartment 35. The function and operation of this compartment in connection with the devices shown in FIGS. 4-5 will be described later.

The legs 23, 25 may be mounted onto the base 13 by available hinges. Each pair of legs may be connected together as with a bar to provide further support for the radio when the legs are extended and to allow a user to unfold the legs in pairs instead of unfolding them individually. When the legs are in the position shown in FIG. 1, a portion of the hinge 19 and 21 extend beyond the bottom surface of the base 13 and the bag 1 so that the bag 1 can be placed on a surface and be supported by the extended portion of the hinges.

The radio 10 never needs to be taken out of the protective bag 1 of my invention. Battery power is provided by a rechargeable battery 2 which is placed in the rechargeable battery compartment 35 in electronic device 10. With reference to FIGS. 4-5, the rechargeable battery 2 is connected to the terminals of the existing battery compartment of the radio 10 using an special spring loaded electrical connector. The battery 2 is connected to a connector 8 via a conductor 6. Connector 8 is connected via wire 12 to a central conductor in a spring loaded device having central spring 14 and two conductive cylinders 16 and 18. The connector shown in FIG. 5 includes two cylinders 20, 24 having conductive points 20' and 24' on the ends thereof Each of the cylinders are connected to each other by a spring 22. An two conductor wire 28 is connected to each cylinder centrally of the spring 22 and to a connector 26. In the usual case of a radio 10 which employ four "D" size batteries, two of the spring loaded connectors is placed into the battery compartment, one connector taking the place of two batteries. The spring pressure securely holds the ends against the battery contacts provided for in the battery compartment. The spring loaded connectors are manufactured in different sizes commensurate with the dimensions of the batteries used in devices 10.

As will now be seen, further modifications to the method and apparatus of the invention may be made without departing from the spirit and scope of the invention; accordingly, what is sought to be protected is set forth in the appended claims.
