Abstract

Apparatus and methods directed to a hand holdable flashlight having a grooved rear cap for being secured to an object, through utilization of an interface device securable to the rear cap and to the object. The grooved rear cap also implements securement of a removable guard for protecting a rear end switch actuator from being accidentally actuated in situations when the flashlight is not secured to the interface device.

Claims

1. Flashlight apparatus securable to an object, comprising in combination:

a flashlight including a battery housing and a rear cap secured to said housing, said rear cap having a longitudinal axis;

a groove in said rear cap perpendicular to said longitudinal axis; and

an interface device including a first portion adapted to be removably received by said groove for holding said flashlight and a second portion adapted to be secured to the object.

2. The apparatus according to claim 1, wherein:

said first portion of said interface device includes an arcuate member for being fitted into said groove.

3. The apparatus according to claim 2, wherein:

said groove is an annular groove.

4. The apparatus according to claim 3, further including:

another member adapted to be fitted into said groove for securing said arcuate member to said rear cap when said arcuate member is fitted into said groove.

5. The apparatus according to claim 4, wherein:

said other member is arcuate.

6. The apparatus according to claim 5, wherein:

each of said arcuate member and said other member define a semi-circle.

7. The apparatus according to claim 1, including:

a front lamp assembly secured to said housing;

a push button rearwardly projecting from said rear cap for controlling energization of a lamp in said lamp assembly by batteries in said housing;

a substantially cylindrical elastomeric cover having a radially inward ledge at one end removably receivable by said groove, said cover longitudinally extending laterally of said push button when said ledge is received by said groove.

8. The apparatus according to claim 1, the object being a rail mount for a firearm, wherein:

said second portion includes a clamp for the rail mount.

9. In a flashlight including a rear cap having a longitudinal axis, the flashlight including a switch having a push button switch actuator projecting from the rear cap, the improvement comprising:

a groove in said rear cap perpendicular to said longitudinal axis; and

a substantially cylindrical elastomeric cover having a radially inward ledge at one end removably received by said groove, said cover longitudinally extending laterally of said push button.

10. The flashlight according to claim 9, wherein:

said groove is an annular groove.

11. In a method of securing a flashlight to an object, the steps comprising:

providing a flashlight including a rear cap having a longitudinal axis;

providing a groove in said rear cap perpendicular to said longitudinal axis;

providing an interface device having a first portion for being removably received by said groove for holding said flashlight and a second portion for being removably secured to the object;

securing said interface device to the object; and

placing said flashlight to said interface device with said first portion received by said groove.

12. The method according to claim 11, further including:

fitting a securing member into said groove; and

securing said securing member to said first portion of said interface device.

13. The method according to claim 11, wherein:

said groove is an annular groove;

said first portion of said interface device includes an arcuate member for being fitted into said groove; and

during said flashlight placing step, said flashlight is placed to said interface device with said arcuate member fitted in said groove.

14. The method according to claim 13, including:

fitting another arcuate member into said groove; and

securing said other arcuate member to said arcuate member of said first portion.

15. The method according to claim 14, the object being a rail mount for a firearm, wherein

said second portion of said interface device includes a clamp for the rail mount, the method including:

clamping said clamp to the rail mount.

16. The method according to claim 11, wherein

said flashlight includes a push button switch actuator rearwardly extending from said rear cap, the method including:

providing a substantially cylindrical elastomeric switch guard having a radially inward ledge at one end for being fitted into said groove;

removing said flashlight from said interface device; and

installing said elastomeric switch guard on said rear cap with said ledge fitted into said groove.

17. In a method of preventing accidental switching of a flashlight, the steps comprising:

providing a flashlight including a rear cap and a push button switch actuator rearwardly extending from said rear cap;

providing a groove in said rear cap perpendicular to said longitudinal axis;

providing a substantially cylindrical elastomeric switch guard having a radially inward ledge at one end for being fitted into said groove; and

installing said elastomeric switch guard on said rear cap with said ledge fitted into said groove.

18. The method according to claim 17, including:

providing an interface device having a first portion for being removably received by said groove for holding said flashlight and a second portion for being removably secured to an object;

removing said elastomeric switch guard from said rear cap; and

placing said flashlight to said interface device with said first portion received by said groove.

19. The method according to claim 18, further including:

fitting a securing member into said groove; and

securing said securing member to said first portion of said interface device.

20. The method according to claim 18, wherein:

said groove is an annular groove;

said first portion of said interface device includes an arcuate member for being fitted into said groove; and

during said flashlight placing step, said flashlight is placed on said interface device with said arcuate member fitted in said groove.

21. The method according to claim 20, including:

fitting another arcuate member into said groove; and

securing said other arcuate member to said arcuate member of said first portion.

22. The method according to claim 21, the object being a rail mount for a firearm, wherein

said second portion of said interface device includes a clamp for the rail mount, the method including:

clamping said clamp to the rail mount.

23. A method for securing a flashlight to an object and for preventing accidental switching of the flashlight, comprising:

providing a flashlight including a rear cap having a longitudinal axis and a push button switch actuator rearwardly extending from said rear cap;

providing a groove in said rear cap perpendicular to said longitudinal axis;

providing a substantially cylindrical elastomeric switch guard having a radially inward ledge at one end for being fitted into said groove;

providing an interface device having a first portion for being removably received by said groove for holding said flashlight and a second portion for being removably secured to the object; and

in the alternative,

securing said interface device to the object and placing said flashlight to said interface device with said first portion received by said groove, or

installing said elastomeric switch guard on said rear cap with said ledge fitted into said groove.
