Module to provide intermittent light with movement
US RE37220 E1
Abstract
An improved module of the type having a light emitting diode and a wafer battery held in the case. The module has a case having a floor, a lighted end and an LED supporting cavity at the lighted end. An LED is supported in the case so that its lower conductor is adjacent the floor and its upper conductor is supported in a cantilevered manner from the transparent lens portion of the LED. A wafer battery having a positive and a negative terminal on each side thereof, is positioned so that one of its terminals continuously contacts the lower conductor of the LED and the upper conductor is positioned so that it is spaced from the other terminal of the wafer battery. A weight member is held above the upper terminal of the LED and the weight member has sufficient weight so that it will move the upper conductor downwardly when the weight is moving downwardly by inertia but will not have sufficient weight to move the upper conductor into contact with the wafer battery when the module is at rest. The module is thus intermittently lighted when the case is moved up and down but is turned off when the case is at rest.

Description
BACKGROUND OF THE INVENTION

The field of the invention is footwear, and the invention relates more particularly to footwear with molded shoes of the type generally referred to as “gym shoes” and furthermore, of the type of “gym shoe” that has a light in the sole thereof.

Gym shoes, or more specifically basketball, jogging, and tennis shoes, have become a large selling product particularly to the youth. Since many such shoes are often worn at night, ways are needed to improve visibility for safety. Various designs have been devised for providing a bright light in the sole of a shoe. Applicant's co-pending application, Ser. No. 07/806,925 filed Dec. 11, 1991, shows a design of intermittently lighted shoe which utilizes the weight of the wearer to move down a conductor of a light-emitting diode into contact with a wafer battery. While this design is very satisfactory for most uses, a design which does not require the wearer to depress and deform the lighted module, would be useful. Furthermore, more of an on and off flashing action to the light-emitting diode would provide a somewhat more flashy appearance which is beneficial from a marketing as well as a safety standpoint, by providing a more visible signal.

SUMMARY OF THE INVENTION

It is an object of the present invention to provide a gym shoe which has the ability to emit light as the shoe is moved during walking and running.

The present invention is for an improved module for use in the sole of a shoe which has a light-emitting diode and a wafer battery held in a case. A light-emitting diode is supported in the case and has an upper conductor and a lower conductor. The lower conductor is in continual contact with one of the terminals of a wafer battery and the second conductor of the LED is positioned just above the other terminal of the wafer battery. A weight member is positioned above the upper terminal of the LED and when at rest, is not heavy enough to move the conductor downwardly into contact with the terminal of the wafer battery. However, when the shoe is moved downwardly and stopped, the inertia of the weight member has sufficient force to complete the contact and turn on the LED. The effect is a flashing light which flashes on as the shoe is being moved but remains off when the shoe is at rest. Preferably the weight member is a hinged weight member.

BRIEF DESCRIPTION OF THE DRAWINGS

FIG. 1 is a perspective view of the module of the present invention held in the sole of a shoe which is shown in phantom view.

FIG. 2 is an exploded perspective view of the module of FIG. 1.

FIG. 3 is a plan view thereof.

FIG. 4 is an enlarged cross-sectional view taken along line 44 of FIG. 1 with the LED off.

FIG. 5 is a cross-sectional view analogous to FIG. 4 except that the LED is on.

DESCRIPTION OF THE PREFERRED EMBODIMENTS

An improved module of the type having a light emitting dime and a wafer battery held in a case is shown in FIG. 1 and indicated generally by reference character 10. Module 10 has a case 11 which has a floor 12 and a pair of walls 13 and 14. Walls 13 and 14 each have a groove and the groove in wall 14 is indicated by reference character 15. These grooves hold a wafer battery 16 as shown best in FIG. 3.

A light-emitting diode (LED) 17 has a transparent lens portion 18, an upper conductor 19, and a lower conductor 20. Case 11 has a lighted end 21 which includes an LED supporting cavity 22. A weight member 23 has a hinge 24, a hinge arm 25, and a weight portion 26. An opening 27 permits the weight member 23 to be captured by fitting in a groove 28 in case 11 as shown best in FIG. 1 and FIGS. 4 and 5.

Turning now to FIG. 4, it can be seen that lower conductor 20 abuts floor 12 and also the negative terminal 29 of wafer battery 16. It is thus in continuous contact with the negative terminal 29. The upper conductor 19 is supported in a cantilevered manner from transparent lens portion 18 and is spaced away from positive terminal 30. The downward force of weight portion 26 is not sufficient to overcome the biased force of cantilevered upper conductor 19. However, when the module 10 is moved upwardly, (or its downward movement is stopped), the weight portion 26 moves downwardly by inertia as shown in FIG. 5. This causes the upper conductor 19 to make contact with the positive terminal 30. Since the lower conductor 20 is in continuous contact with the negative terminal 29, this causes the LED to light. When the inertial force ceases to move weight portion 26 downwardly, the biased force of cantilevered upper connector 19 returns the weight member 23 back to the position shown in FIG. 4 turning off the LED.

The resulting device is very economical to manufacture, automatically turns off when not in use and is highly reliable. While a hinged weight is shown in the drawings, the weight need not be hinged, and can be merely supported by the upper conductor 19 above the battery as, for instance, a cavity above the battery. The essential feature is the combination of a weight which at rest is insufficient to force the upper conductor down, but which is sufficient in movement by inertia to move the upper conductor into contact with the wafer battery.

The present embodiments of this invention are thus to be considered in all respects as illustrative and not restrictive; the scope of the invention being indicated by the appended claims rather than by the foregoing description. All changes which come within the meaning and range of equivalency of the claims are intended to be embraced therein.
