Holster having pushrod disengagement locking element

1. A holster, comprising:

a holster body defining an at least partial cavity portion capable of receiving at least a portion of a handgun therein;

a locking element that extends from a proximal end to a distal end, wherein a helical portion, defining a helical ramp surface, begins at or proximate said proximal end and extends toward said distal end of said locking element, wherein said locking element is at least partially rotatable between a locking element engaged position and a locking element disengaged position, wherein at least a portion of said locking element retains said handgun in said holster in said locking element engaged position, via interaction between at least a portion of said locking projection portion and an interior surface of a trigger guard of said handgun, and permits release of said handgun when in said locking element disengaged position; and

an elongate pushrod, wherein at least a portion of said pushrod is slidably positioned within at least a portion of said holster body, such that at least a first end of said pushrod may be urged within said at least partial cavity portion to contact said helical ramp surface of said helical portion of said locking element such that if said pushrod is urged toward said locking element, interaction between said first end of said pushrod and said helical ramp surface of said helical portion causes said locking element to rotate toward said locking element disengaged position.

2. The holster of claim 1 , wherein said holster body comprises a pair of opposed wall portions comprising a first wall portion and a second wall portion and a pair of opposed wall portions comprising a third wall portion and a fourth wall portion.

3. The holster of claim 1 , wherein said helical portion comprises a multipart or multi-ramped surface.

4. The holster of claim 1 , wherein said helical ramp surface is a helical recess or a helical protrusion.

5. The holster of claim 1 , wherein said helical ramp surface is formed in or around at least a portion of said locking element.

6. The holster of claim 1 , wherein said helical ramp surface provides an incurved rim that curves around at least a portion of said locking element.

7. The holster of claim 1 , wherein said helical ramp surface generally follows a spiral or a curve along a portion of said locking element.

8. The holster of claim 1 , wherein at least a portion of said pushrod is positioned within a portion of a pushrod channel formed in or through at least a portion of said holster body.

9. The holster of claim 1 , wherein at least a portion of said locking element retains said handgun in said holster in said locking element engaged position, via interaction between at least a portion of said locking projection portion and an interior surface of a trigger guard of said handgun and permits release of said handgun when in said locking element disengaged position.

10. The holster of claim 1 , wherein in said locking element engaged position at least a portion of said locking projection portion of said locking element protrudes into said at least partial cavity portion a sufficient distance to extend inside at least a portion of a trigger guard of said handgun if said handgun is seated within said at least partial cavity portion of said holster, wherein in said locking element disengaged position at least a portion of said locking projection portion of said locking element is withdrawn from said at least partial cavity portion a sufficient distance to be withdrawn from said trigger guard of said handgun if said handgun is seated within said at least partial cavity portion of said holster and permit release of said handgun when in said locking element disengaged position.

11. The holster of claim 1 , wherein in said locking element engaged position at least a portion of said locking projection portion of said locking element protrudes into said at least partial cavity portion a sufficient distance to extend inside at least a portion of a trigger guard of said handgun if said handgun is seated within said at least partial cavity portion of said holster, wherein in said locking element disengaged position at least a portion of said locking projection portion of said locking element is withdrawn from said at least partial cavity portion a sufficient distance to be withdrawn from said trigger guard of said handgun.

12. The holster of claim 1 , wherein if said locking element is in said engaged position, at least a portion of said locking projection portion of said locking element protrudes into said at least partial cavity portion a sufficient distance to extend inside at least a portion of said trigger guard of said handgun if said handgun is seated within said at least partial cavity portion of said holster.

13. The holster of claim 1 , wherein said locking element is biased to said locking element engaged position and said release lever is biased to said release lever engaged position.

14. The holster of claim 1 , wherein said release lever is accessible by a user's thumb.

15. The holster of claim 1 , further comprising a release lever attached or coupled to a second end of said pushrod.

16. A holster, comprising:

a holster body defining an at least partial cavity portion;

a locking element that extends from a proximal end to a distal end, wherein a helical portion, defining a helical ramp surface, begins at or proximate said proximal end and extends toward said distal end of said locking element, wherein said locking element is at least partially rotatable between a locking element engaged position and a locking element disengaged position, wherein in said locking element engaged position at least a portion of said locking projection portion of said locking element protrudes into said at least partial cavity portion, wherein in said locking element disengaged position at least a portion of said locking projection portion of said locking element is withdrawn from said at least partial cavity portion; and

an elongate pushrod, wherein at least a portion of said pushrod is slidably positioned within at least a portion of said holster body, wherein if said pushrod is urged toward said locking element, interaction between a first end of said pushrod and said helical ramp surface of said helical portion causes said locking element to rotate toward said locking element disengaged position.

17. The holster of claim 16 , wherein said helical ramp surface is formed in or around at least a portion of said locking element.

18. The holster of claim 16 , wherein said helical ramp surface provides an incurved rim that curves around at least a portion of said locking element.

19. The holster of claim 16 , further comprising a release lever attached or coupled to a second end of said pushrod.

20. A holster, comprising:

a holster body defining an at least partial cavity portion;

a locking element that extends from a proximal end to a distal end, wherein a helical portion, defining a helical ramp surface, begins at or proximate said proximal end and extends toward said distal end of said locking element, wherein said locking element is at least partially rotatable between a locking element engaged position and a locking element disengaged position, wherein in said locking element engaged position at least a portion of said locking projection portion of said locking element protrudes into said at least partial cavity portion, wherein in said locking element disengaged position at least a portion of said locking projection portion of said locking element is withdrawn from said at least partial cavity portion; and

an elongate pushrod, wherein at least a portion of said pushrod is slidably positioned within at least a portion of said holster body, wherein if said pushrod is urged toward said locking element, interaction between a first end of said pushrod and said helical ramp surface of said helical portion causes said locking element to rotate toward said locking element disengaged position.
