Detailed Description of the Preferred Embodiments
Turning now descriptively to the drawings, in which similar reference characters denote similar elements throughout the several views the figures illustrate a device 10 for sterilizing and storing toothbrushes 12 consisting of a container 14 having a first half segment 16 and a second half segment 18 hinged together at 20 so that in one instance the segments can be in an opened position and in another instance the segments can be in closed position. A lamp 22 is disposded within the first half segment 16 for radiating ultraviolet rays. Holders 24 are provided for supporting the toothbrushes 12, in which the holders 24 are spaced apart and affixed to interior of the first half segment 16 and the second half segment 18. Reflecting surfaces 26 are on the interior of the first half segment 16 and the second half segment 18 for directing rays from the lamp 22 over bristels 28 of the toothbrushes 12. An electrical connection 30, such as a power cord, goes from the lamp 22 to a power source 32, such as a battery or house lighting circuit. A magnetic fastener 34 is for removably securing the first half segment 16 to the second half segment 18 in the closed position. A mechanism 36 is for automatically denerginzing the lamp 22 when the first half segment 16 and the second half segment 18 are in the opened position at a predetermined distance.
The magnetic fastener 34 includes a magnetizable member 38 affixed to the second half segment 18 of the container 14. A magnetic member 40 is affixed to the first half segment 16 of the container 14 so that when the segments are in the closed position the magnetic member 40 and the magnetizable member 38 will make contact with each other.
As shown in FIG. 2, the mechanism 36 includes a switch 42 in the electrical connection 30 and is disposed onto the first half segment 16 of the container 14 for controlling energization of the lamp 22. An actuator 44 is attached to the second half segment 18 of the container 14 and is controlled by movement thereof for operating the switch 42 to energize the lamp 22 when the second half segment 18 is in the closed position and to deenergize the lamp 22 when the second half segment 18 is in the opened position.
The switch 42 includes a stationary contact 46 mounted to the interior 26 of the first half segment 16 of the container 14. A moveable arm 48 is pivotly mounted at 50 to the interior 26 of the first half segment 16 while an adjustable contact 52 is disposed onto the moveable arm 48. A spring 54 is disosed between the adjustable contact 52 and the moveable arm 48 to bias the adjustable contact 52. In one instance the adjustable contact 52 will permit the second half segment 16 of the container 14 to go into the closed position before the lamp 22 is energized and in another instance permit the second half segment 16 to go into the closed position after the lamp 22 is energized.
FIG. 3 shows a modified mechanism 36a wherein the switch 42a includes a stationary contact 46a mounted to the interior 26 of the first half segment 16 of the container 14. A moveable arm 48a is pivotly mounted at 50a to the interior 46 of the first half segment 16. A first spring 56 is disposed between the moveable arm 42a and the interior 26 of the first half segment 16 to bias the moveable arm 42a. A moveable contact 52a is mounted to other end of the second spring 54a to bias the moveable contact 52a towards the stationary contact 46a so that the moveable contact 52a will keep energizing the lamp 22 when the second half segment 16 is partially going into the open position so that a person (not shown) can view the lamp 22 to check that it is operating.
The magnetic member 40a of the magnetic fastener 34a shown in FIG. 3 is now an electromagnet in the electrical connection 30 and is still disposed onto the first half segment 16 of the container 14 so that when the segments are in the closed position the switch 42a will close and the electromagnet 40a will activate while making contact with the magnetizable member 38.
While certain novel features of this invention have been shown and described and are pointed out in the annexed claims, it will be understood that various omissions, substitutions and changes in the forms and details of the device illustrated and in its operation can be made by those skilled in the art without departing from the spirit of the invention.
