Claim 1
Independent Claim
289 words
An adjustable leg support for automatic weapons, said support comprising a sleeve defining coupling means that is adapted to engage a tubular part of the weapon, two lateral wings integral with said sleeve, said wings being diametrically opposed to each other and positioned on opposite sides of said coupling means, two elongaged folding rods each having one end pivotally mounted on said wings and angularly displaceable from a parallel position to a perpendicular position with respect to the longitudinal axis of said sleeve, said parallel and perpendicular positions being limited by shoulders provided on said wings, and spring-loaded arresting means mounted on said rods and arranged to engage said wings, each of said folding rods comprising first and second rodlike elements pivotally coupled to each other at their contiguous extremities, the opposite extremity of each said first rod-like element being mounted on said respective wing, each said second rod-like element being adapted to move angularly from an alignment position to a non-alignment position relative to said respective first rod-like element, said opposite extremity of each said first rod-like element being pivoted on a lateral ear of said sleeve and wherein its contiguous extremity includes two arcuate portions that are provided with a plurality of angularly spaced apart notches on the periphery thereof, each said second rod-like element being coupled to said respective arcuate portions on said first rod-like elements by means of a transverse pin, said second rod-like elements each including a spring-loaded, pivotally mounted lever having at least one terminal projection facing toward and engaging one of said notches of said arcuate protions on said first rod-like elements so as to define the angular relationship of said second rod-like elements with respect to said respective first rod-like elements.
Claim 2

Claim 4
Dependent Claim
35 words
The support as defined in claim 2, wherein said releasing engagement means is defined by an arcuate rib on said sleeve, said rib being adapted to be received in an arcuate throat on said weapon.
Claim 5
Dependent Claim
22 words
The support as defined in claim 1, wherein the biasing force of said spring-loaded arresting means is provided by a compression spring.
Claim 6
Dependent Claim
23 words
