Locking device safety mechanism and related holster assembly

1. A firearm holster assembly comprising:

a holster pocket having an interior volume for accommodating a firearm therewithin;

a locking device mounted within the interior volume of the holster pocket for selectively impeding the withdrawal of the firearm therefrom, the locking device including an operating lever extending outwardly from the holster pocket and operable by a user to disengage the locking device from the firearm; and

a locking device safety mechanism mounted to the holster pocket and including an operating arm selectively operable to pivot forwardly to clear the operating lever and remain in that position until returned by a user and to overlie and inhibit access to and operation of the operating lever, the operating arm having a thumb tab at its upper end which selectively blocks and shields the operating lever from being engaged until the thumb tab is moved to a clear position that does not block or shield the operating lever;

the locking device safety mechanism further includes a mounting plate and a pivot connection to which the operating arm is pivotably connected,

the mounting plate releasably engages the operating arm in a blocking position which inhibits operation of the operating lever, and is pivoted by the user to a clear position, in which the operating arm permits access to and operation of the operating lever of the locking device.

2. The assembly of claim 1 , wherein the operating arm includes a resilient leg and the mounting plate includes a pair of spaced detents that releasably engage the resilient leg respectively in the blocking and the clear position.

3. The assembly of claim 2 , wherein the mounting plate includes an operating arm engagement wall, the pair of spaced detents being located in a resilient leg detent section of the operating arm engagement wall.

4. The assembly of claim 3 , wherein the operating arm engagement wall further includes an operating arm limit section, the operating arm limit section limiting the pivotal motion of the operating arm beyond the blocking and clear positions.

5. The assembly of claim 1 , wherein the locking device includes a saddle from which the operating lever extends, the saddle being dimensioned to accommodate an upper portion of the firearm thereunder, the saddle having at least one firearm engagement protrusion extending therefrom for releasable engagement with a corresponding surface of the firearm, the operating lever being operable to disengage the engagement protrusion from the corresponding surface of the firearm.

6. The assembly of claim 1 , further comprising an adjustable tension device arranged proximate a muzzle end of the holster pocket and adjustable for proper positioning of the firearm by the locking device.

7. A locking device safety mechanism for a firearm holster assembly having a locking device within a holster of the holster assembly and an elongate operating lever with an end within the holster operable with the locking device to open the locking device and a free end outwardly of the holster and engageable by a thumb of a user to unlock the locking device, the mechanism comprising:

a safety mounting plate adapted for mounting the holster; and

a safety operating arm pivotably connected to the mounting plate and having a first end with a safety thumb tab and a second end overlying the mounting plate, such that, with the mounting plate mounted to the holster, the safety operating arm is selectively pivotable from a blocking position in which the safety thumb tab covers and blocks access to the end of the locking device elongate operating lever and any unlocking movement by the elongate operating lever until a user moves the safety thumb tab forward to a clear position to permit unlocking movement of the operating lever.

8. The mechanism of claim 7 , wherein the mounting plate releasably engages the safety operating arm in a blocking position, and in such blocking position the operating arm prevents movement of the operating lever, and in the clear position, the safety operating arm permits operation of the operating lever.

9. The assembly of claim 8 , wherein the safety operating arm second end includes a resilient leg and the mounting plate includes a pair of spaced detents that releasably and respectively engage the resilient leg in the blocking and clear positions.

10. The mechanism of claim 9 , wherein the mounting plate includes an operating arm engagement wall, the pair of spaced detents being located in a resilient leg detent section of the operating arm engagement wall.

11. The mechanism of claim 10 , wherein the operating arm engagement wall further includes an operating arm limit section, the operating arm limit section limiting the pivotal motion of the safety operating arm beyond the blocking and clear positions.

12. A firearm holster assembly comprising:

a holster pocket having an interior volume for accommodating a firearm there within;

a locking device mounted within the interior volume for selectively impeding the withdrawal of the firearm therefrom, the locking device including a saddle having at least one firearm engagement protrusion extending therefrom for releasable engagement with a corresponding surface of the firearm, and an operating lever extending from the saddle out of the holster pocket, the operating lever being operable to disengage the engagement protrusion from the corresponding surface of the firearm; and

a locking device safety mechanism mounted to the holster pocket and including an operating arm having a first end with a thumb tab and a second end with a resilient leg, and a mounting plate mounted to the holster pocket with the operating arm pivotably connected thereto, the mounting plate having a pair of spaced detents that selectively releasably and engage the resilient leg, respectively, in a clear position and a blocking position, in which the first thumb tab overlies and shields the operating lever, and in the clear position, in which the thumb tab is moved forward to a clear position of the operating lever and permits access by a user to the operating lever of the locking device.

13. The assembly of claim 12 , further comprising a belt attachment plate mounted exteriorly to the holster pocket by at least one fastener, the locking mounting plate being mounted to the holster pocket by the at least one fastener, between the belt attachment plate and the holster pocket.

14. The mechanism of claim 12 , wherein the mounting plate includes an operating arm engagement wall, the pair of spaced detents being located in a resilient leg detent section of the operating arm engagement wall.

15. The mechanism of claim 14 , wherein the operating arm engagement wall also has an operating arm limit section, the operating arm limit section limiting the pivotal motion of the operating arm beyond the blocking and clear positions.
