## Background
FIELD OF THE INVENTION
The present invention relates in general to a display case, and particularly a jewelry display case. More particularly, the present invention pertains to a novel way of displaying a jewelry item that is disposed in the case or jewelry box by means of illuminating the jewelry item. Even more particularly, the present invention relates to a novel jewelry display case or box in which a sensing arrangement is used to control the illumination.
BACKGROUND OF THE INVENTION
There presently exist jewelry boxes that contain a light source. The light source is typically activated when the jewelry box is opened. Examples are found in U.S. Pat. Nos. 3,937,320; 5,329,433 and 7,325,940. Typically a mechanical switch of some type is used. This may be, for example, a switch at the hinge that closes when the jewelry box is opened to activate the light source. One problem associated with these prior art devices is that the light source may stay on for an indefinite period of time draining the battery that activates the light source.
Accordingly, it is an object of the present invention to provide a novel jewelry product, particularly a jewelry box in which the jewelry item that is contained in the jewelry box is selectively illuminated by means of a sensory signal from a user.
Another object of the present invention is to provide a novel jewelry box or case in which the jewelry item that is contained in the jewelry box is selectively illuminated by using such means as a motion detector, an ambient light sensor, a touch sensor or a proximity sensor.
Still another object of the present invention is to provide a novel jewelry box or case in which the sensory signal is facilitated by simple and inexpensive means that can be readily attached with the jewelry box or case.

DETAILED DESCRIPTION
Reference is now made to FIGS. 1 and 2 that both illustrate a display case 10 that is basically comprised of a base 12 and a cover 14. FIGS. 1 and 2 illustrate one version of the display case. However, the display case can be provided in many different forms including, but not limited to, a clamshell construction or a rocket box construction.
The perspective view of FIG. 1 illustrates the display case in an open position. On the base 12, there may be provided a display area 13 for containing an item such as the illustrated jewelry item 15. FIG. 1 also illustrates on an internal surface of the cover 14 the light source 20 which may be in the form of one or more LED's. Also associated with the cover 14 is the sensor 24. As indicated, the light source is disposed in the interior compartment formed between the cover and base, is supported at an internal surface of the cover, and when illuminated, casts a light beam 17 on the jewelry item 15 so as to highlight the jewelry item.
Reference to FIG. 2 also illustrates the base 12 and the cover 14 in a closed position. There may be associated with either the cover or the base what is referred to herein as a touch zone 30. In the particular embodiment illustrated in FIG. 2 this “touch zone” is disposed at the cover 14. In one embodiment the sensor 24 of FIG. 1 may instead be disposed at the area 30 of FIG. 2. For example, the sensor may be in the form of a touch, proximity or motion detector so that the user simply has to take some motion or touching adjacent to the area 13 in order to control the light source; particularly to activate the light source once the motion or touching occurs.
Reference may now be made to the circuit diagram of FIG. 3. This depicts the manner in which the sensor 24 and the light source 20 are arranged in a series circuit with the battery 30. The battery 30 may be provided at any location within the display case 10. The battery 30 may be provided in the base 12 along with the wiring that interconnects the battery with the sensor 24 and the light source 20 in the series circuit illustrated in FIG. 3. The sensor 24 is for sensing a sensory condition or, in one embodiment, is in the form of an ambient light detector. A first embodiment of the sensor 24 is illustrated in the fragmentary circuit illustrated in FIG. 4. The sensor is in the form of a motion detector 34 that would also be connected in a series circuit between the battery and the light source. The motion detector 34 may be of conventional design that initiates a control signal for essentially bridging the connection between the battery 30 and the light source 20.
FIG. 5 also illustrates an alternate embodiment in which the sensor is in the form of an ambient light detector 36. Refer also to the fragmentary circuit diagram of FIG. 6 that includes both a motion detector 34 and the ambient light detector 36 in a series circuit diagram that also includes a controller 38. The controller 38 may be in the form of a monostable device that allows the light source to be illuminated but only for a set predetermined period of time. This monostable device operates so that it essentially provides a “pulse” of a certain duration. It is only during that pulse duration that the light source is illuminated. After the pulse duration is over, the pulse ends and thus the illumination of the light source ends. This control prevents the light source from staying on for an indefinite period of time.
In the embodiment of FIG. 6 this is a condition wherein both a motion (34) is sensed as well as ambient light (25). This can occur when the display case is open. As a matter of fact, the mere opening of the display case provides sufficient motion so that both the detector 34, as well as the detector 36, are activated. In that instance the light source 20 can be operated from the battery 30. The controller 38 provides the aforementioned delay period. As indicated previously, this can be in the form of a monostable vibrator type of device that essentially pulses the light source or LED to its illuminated state but only for a predetermined period of time as set by the monostable controller 38.
The use of a controller 38 can also be provided in association with either the motion detector or the light detector. For example, the user may provide some movement, when the display case is open, that is detected and in turn causes the light source to illuminate. There may be situations in which it is not desired to have the light source be continuously illuminated and with the use of the controller 38, one can control the duration of illumination of the light source. This controller 38 may be used separately with either the motion detector 34 or the ambient light detector 36.
Thus, as mentioned previously, the motion detector may be provided either on the outside of the case or inside the case 10. It is preferred that these detectors be placed within the internal case compartment defined between the base 12 and cover 14; particularly the ambient light detector. If both the motion detector and the light detector are within the internal jewelry case compartment, when the user opens the case 10 there may well be enough motion to excite both the motion detector and the light detector. Because the internal compartment is completely dark when the case is closed; once the case is opened virtually any level of light will activate the ambient light detector and the mere opening of the case will most likely also activate the motion detector. Thus, in another embodiment of the invention either detector 34 or 36 may be used without requiring the use of both detectors. For the light detector 36 this device responds to detecting an adjustable amount of light to, in turn, activate the light source 20. The light detector 36 may be of conventional design that initiates a control signal for essentially bridging the connection between the battery 30 and the light source 20.
Reference is also now made to FIGS. 7 and 8. These figures describe further embodiments of the present invention. FIG. 7 illustrates a touch sensor 40 that can be in the circuit of FIG. 3. FIG. 8 illustrates a proximity sensor 42 that can be in the circuit of FIG. 3. The touch sensor 40 may be disposed within the display case inner compartment or at an external surface such as illustrated in FIG. 2. In either case it is preferred to also use the controller of FIG. 6 so that the illumination of the jewelry item is limited to a set predetermined of time. In a sense the proximity sensor of FIG. 8 may be considered as substantially the same as the motion detector 34 of FIG. 4. The proximity sensor 42 may also be disposed within the display case inner compartment or at an external surface such as illustrated in FIG. 2. In either case it is preferred to also use the controller of FIG. 6 so that the illumination of the jewelry item is limited to a set predetermined of time.
As previously mentioned, FIG. 7 shows a fragmentary view of the circuit of FIG. 3 illustrating the sensor as a touch sensor FIG. 8 illustrates a fragmentary view of the circuit of FIG. 3 illustrating the sensor as a proximity sensor. In still another embodiment of the present invention, either of these sensors illustrated in FIGS. 7 and 8 can also be replaced by a sound sensor or transducer. In that way, the highlighting of the item can be based upon the detection of a sound.
Having now described a limited number of embodiments of the present invention, it should now be apparent to those skilled in the art that numerous other embodiments and modifications thereof are contemplated as falling within the scope of the present invention, as defined by the appended claims. For example, the concepts of the present invention can be applied to virtually any type of display case that displays any item whether a jewelry item or not.
