Bag holder
First Claim
1. A bag holder comprising an articulatable frame for removably receiving around it an out-turned mouth of a bag, which frame is a closed figure constituted of two elongated flexible cooperable elements, each of said elements being substantially rectangular in cross section taken transversely to the length of said elements, means articulatingly connecting the elements to each other at their ends for enabling relative pivotal movement therebetween, means for attaching one of said elements to a support and handle means on the other of said elements by which traction may be exerted, both of said elements being pre-bowed in the same direction in a bag closing configuration, both being concave with respect to the support, both of said elements being movable through an overcenter snap position to a bag-opening configuration by traction on said handle means in which in the bag-opening configuration the elements at their middle portions are spaced apart and in which the element having said attaching means is given a reverse bow in opposite direction to be bowed convexly with respect to the support, the other element remaining bowed concavely with respect to the support, and means resiliently biasing the frame to the bag closing configuration.

Abstract
A bag holder of the type wherein a bag mouth is to be received and supported by a closed-figure frame of variable shape, the frame being made up of two elements, one being adapted to be attached at one side to a support and the other at an opposite side having handle means for the application of traction to the frame to bring it to a bag-opening configuration in which the elements are oppositely bowed so that their middle portions are spaced apart, the two elements lying face to face in a bag-closing configuration and being articulated together at their ends, and is characterized by the elements being biased to a bowed bag-closing configuration in which both are bowed in one direction. The biasing will be such that the element adapted to be attached to a support is concave (relative to the support) in the bag-closing configuration, traction on the handle means to bring the frame to the bag-opening configuration bring the said element through a straight to a convex configuration, the other element being concave (relative to the support) at all times.

15. A bag holder for releasably supporting a bag in a normally closed condition comprising a bag mouth holding frame including first and second elongated flexible elements pivotably connected at the corresponding ends thereof, attachment means carried by the first of said frame elements on a surface thereof remote from said second elemement for securing same to a support surface, handle means carried by the second of said frame elements on a surface thereof remote from said first element to apply a traction force on said frame;
- and means for biasing said first and second frame elements into a complementary arcuate bag-closing configuration in which both of said frame elements are bowed outwardly relative to the support surface, and movable in opposite directions upon the application of a traction force to said handle means to thereby separate the central portions of said frame elements and bring the frame into bag-opening configuration, said first frame element being given a reverse bow in moving from said bag-closing to said bag-opening configuration, and inset notches formed in the ends of said frame adapted to receive an elastic band which passes completely round the frame to hold said bag, said means for biasing said frame elements comprising an elastic member extending between and no further than each end portion of the first element and is at the middle portion of that element spaced away therefrom by the means adapted for attachment to the support.
