Abstract

A charging handle for a rifle having a housing. The handle has a body with an elongated bar having a forward end and a rear end. The bar has a bolt engaging element at the forward end, and a crossbar having an intermediate portion connected to the rear end of the bar. The crossbar has opposed ends extending laterally of the bar. First and second latch elements are connected to the body. The first latch element has a housing-engaging element that engages the housing when the handle is in a forward position. The first and second latch elements are engaged to each other such that pivoting of the second latch element disengages the housing-engaging element from the housing.

Claims

1. A charging handle for a rifle having a housing, the handle comprising:

a body having an elongated bar having a forward end and a rear end;

the bar having a bolt engaging element at the forward end;

a crossbar having an intermediate portion connected to the rear end of the bar;

the crossbar having opposed ends extending laterally of the bar;

first and second latch elements connected to the body;

the first latch element having a housing-engaging element operable to engage the housing when the handle is in a forward position;

the latch elements being spring biased in opposite rotational directions; and

the first and second latch elements being operably engaged to each other such that pivoting of the second latch element pivots the first latch element to disengage the housing-engaging element from the housing.

2. The handle of claim 1 wherein the latch elements are pivotally-connected to the body.

3. The handle of claim 2 wherein each latch element pivots about a different axis.

4. The handle of claim 1 wherein one of the latch elements has a protrusion, and the other latch element has a recess, and wherein the protrusion is received in the recess to constrain the position of each latch element based on the position of the other latch element.

5. The handle of claim 4 wherein the protrusion extends radially from a first pivot axis about which the one latch element pivots, and where the recess has an opening facing away from a second pivot axis about which the other latch element pivots.

6. The handle of claim 4 wherein the protrusion terminates a circular knob having a selected diameter, and wherein the recess is a channel with parallel walls spaced apart by a distance to closely receive the knob.

7. The handle of claim 1 including a spring contacting each of the latch elements, such that the housing-engaging element is biased toward the housing.

8. The handle of claim 1 wherein the spring is a compression spring positioned between the latch elements.

9. The handle of claim 1 where in the body defines a major plane parallel to the bar and the cross bar, and wherein the crossbar defines a slot in a slot plane parallel to the major plane, and wherein at least planar portions of each latch element are received within the slot.

10. The handle of claim 9 wherein at least a portion of each latch element protrudes forwardly from the crossbar when the housing-engaging element is engaging the housing.

11. A latch mechanism for a rifle with a T-shaped charging handle operable to reciprocate with respect to a housing, the mechanism comprising:

a first latch element having a pivot aperture sized to receive a pivot pin mounted to the charging handle;

a second latch element having a pivot aperture sized to receive a pivot pin mounted to the charging handle;

each latch element having an latch engaging element operable to engage the latch engaging element of the other latch element such that pivoting of the second latch element pivots the first latch element;

at least one of the latch element having a housing-engaging element operable to engage the housing; and

a spring for biasing the housing engaging element toward the housing.

12. The mechanism of claim 11 wherein each latch element includes a spring contact portion for contacting the spring.

13. The mechanism of claim 12 wherein the spring contacting portion of the at least one latch element having a housing-engaging element being generally radially opposed from the housing engaging element with respect to the pivot aperture.

14. The mechanism of claim 11 wherein one of the latch-engaging elements is a protrusion, and the other of the latch-engaging element is a recess.

15. The mechanism of claim 14 wherein the protrusion includes at least a portion sized to closely receive the recess.

16. The mechanism of claim 14 wherein the first and second latch element are pivotally interlinked by the engagement of the protrusion and the recess.

17. The mechanism of claim 14 wherein the protrusion has a bulbous end sized to be closely received within the recess.

18. The mechanism of claim 14 wherein the recess is a channel having an open end extending away from the pivot aperture, and having parallel walls.
