Abstract

A collapsible buttstock with automatic deployment has a housing with an opening providing clearance for a buffer tube. Rods slidably couple through respective openings in the housing; the rods each having a hollow cavity accommodating biasing structure for exerting a biasing force against a respective attachment member. A locking element has locking blocks, each engaging a respective one of plural notches on the rods, for locking the rods to an operator support buttstock element, each of the locking blocks comprising a tapered surface. A release trigger with a contoured step engages the tapered surfaces of the locking blocks. When the release trigger is moved, the contoured step engages the tapered surfaces to push locking blocks away from engagement with the notches on the rods, thus allowing the biasing member in each rod to push the respective rod and the operator support buttstock element away from the housing.

Claims

1. A collapsible buttstock with automatic deployment, comprising:

a housing with a first opening configured to provide clearance for a buffer tube, the buffer tube traversing the housing longitudinally through the opening and attaching to a firearm;

two or more rods slidably coupled, via respective attachment members, to the housing through respective second openings in the housing, said two or more rods each comprising a hollow cavity configured to accommodate a biasing member for exerting a biasing force against the respective attachment member;

an operator support buttstock element coupled to an end of the two or more rods;

a locking element comprising two or more locking blocks each configured to engage a respective one of plural notches on the two or more rods for locking the two or more rods and the operator support buttstock element in place, each of the two or more locking blocks comprising a tapered surface; and

a release trigger with a contoured step configured to engage the tapered surfaces of the two or more locking blocks, wherein

when the release trigger is moved by an operator of the firearm, the contoured step engages the tapered surfaces to push the two or more locking blocks away from engagement with the respective notches on the two or more rods, thus allowing the biasing member in each rod to push the respective rod and the operator support buttstock element away from the housing.
