Vertical foregrip leg extender
Devices, and methods of extending legs from vertical fore grip handles on firearms, such as rifles, to different height positions. The vertical fore grip can include expandable bipod legs. The legs can be individually extended to different lengths by moving telescoping rod members in leg housings from retracted positions to extended positions. A lever switch can allow for the legs to be locked into the different extended positions, and depressing the switch can allow for the legs to go back to the retracted positions. Anti-rotation pins and slots can prevent the telescoping members from rotating relative to the legs.
1. A method of extending heights of each respective leg of bipod legs that support firearms, comprising the steps of:
providing a firearm with a vertical fore grip underneath the firearm, the fore grip having bipod stand having two main legs which are positioned at a triangle orientation beneath the vertical fore grip underneath of the firearm;
pulling an inner leg portion from at least one of the two legs so that a bottom of the inner leg extends outward beneath an outer bottom portion of the main leg;
locking the inner leg to a selected height extended position relative to the outer bottom portion of the main leg;
depressing a spring biased latch so that inner leg can ratchet downward to a selected step edge row from a plurality of rows of step edges;
extending the bipod leg stand out from underneath the vertical fore grip; and
activating a switch which when activated causes the bipod leg stand to move from a retracted position with the legs substantially within the vertical fore grip, to release to an expansion position where most of the legs protrude out beneath the vertical fore grip.
2. The method of claim 1 , further comprising the step of:
Preventing the inner leg from rotating relative to the main leg while the inner leg is being pulled to extend outward beneath the outer bottom of the main leg.
3. The method of claim 2 , wherein the preventing step includes the step of:
Sliding a pin extending from the inner leg through a longitudinal slot in the main leg to that the inner leg is prevented from rotating relative to the main leg.
4. The method of claim 1 , further comprising:
adjustably extending each of the legs by an activation switch.
5. The method of claim 4 , further comprising the step of:
separately extending each of the legs by separate activation switches for each of the legs.
6. The method of claim 1 , further comprising the step of:
separately extending each of the legs by separate activation switches for each of the legs.
7. The method of claim 1 , further comprising the step of:
mounting the vertical fore grip to picatinny rails underneath of the firearm.
8. The method of claim 7 , further comprising the step of:
clamping a pair of clamp rails about the picatinny rails underneath the firearm.
9. A method for extending bipod legs from vertical fore grip comprising the steps of:
providing an elongated handle having a top end and a bottom end;
providing a mount on the top end of the handle for mounting the handle to a firearm;
attaching a pair of legs to the elongated handle, the legs having an upper end and a lower end;
activating separate switches in order to extend each of the legs to different lengths beneath the handle;
providing angled footers on the lower end of each of the legs; and
retracting each of the legs into the handle so that the angled footers remain outside the bottom end of the handle.
10. The method of claim 9 , further comprising the step of:
mounting the top end of the elongated handle to picatinny rails underneath the firearm.
11. The method of 9 , further comprising the step of:
providing each of the activation switches on each of the legs.
12. The method of claim 9 , further comprising the step of:
forming a bipod stand beneath the handle with the legs.
13. The method of claim 12 , further comprising the step of:
activating a switch to form the bipod stand beneath the handle.
14. The method of claim 9 , further comprising the step of:
telescopingly extending each of the legs to different lengths beneath handle.
15. A method of extending heights of each respective leg of bipod legs that support firearms, comprising the steps of:
providing a firearm with a vertical fore grip underneath the firearm, the fore grip having bipod stand having two main legs which are positioned at a triangle orientation beneath the vertical fore grip underneath of the firearm;
pulling an inner leg portion from at least one of the two legs so that a bottom of the inner leg extends outward beneath an outer bottom portion of the main leg;
locking the inner leg to a selected height extended position relative to the outer bottom portion of the main leg;
providing angled footers on the lower end of each of the legs; and
retracting each of the legs into the handle so that the angled footers remain outside the bottom end of the handle.
