Bag dispenser

1. A bag dispenser comprising:

a frame including a roller portion for receiving a bag roll defined by a plurality of bags attached to a leading bag to be dispensed, the roller defining a longitudinal axis; and

a non-biased brake plate defining a weight that is heavy enough to capture the leading bag against the frame at a friction application area solely by the weight of the plate without any supplemental forces for providing frictional force on the leading bag to limit sliding thereof, the brake plate pivotally attached to the frame via a pivot arm, the brake plate freely floatable under the weight thereof so as to pivot with respect to the frame between a non-pivoted friction-application position and a pivoted bag roll installment position, the pivot arm configured to pivot with respect to the frame along a pivot plane generally perpendicular to the longitudinal axis;

wherein the brake plate includes a braking portion defining a flat, planar configuration that is configured to contact a flat, planar braking surface defined by the frame for providing the frictional force on the leading bag to be dispensed, the brake plate also including a transition portion defining a curved contact surface for guiding the leading bag from the bag roll to the friction application area defined between the flat, planar braking portion of the brake plate and the flat, planar braking surface of the frame, wherein the curved contact surface of the transition portion is configured to provide additional friction to the leading bag as the leading bag is pulled while also allowing smooth sliding motion of the leading bag.

2. A bag dispenser according to claim 1 , further comprising a bag roll mounted to the roller portion of the frame.

3. A bag dispenser according to claim 1 , wherein the roller portion of the frame is fixedly coupled to the frame and is configured to allow a cylindrical core of the bag roll to rotate therearound for dispensing of the bags.

4. A bag dispenser according to claim 1 , further including a perforator for separating the leading bag from the plurality of bags of the bag roll, the perforator removably attached to the frame.

5. A bag dispenser according to claim 1 , further comprising an accessory mount for mounting an accessory holder to the bag dispenser.

6. A bag dispenser according to claim 1 , wherein the frame is removably mounted on a dispenser support, the dispenser support configured for mounting the frame on a mounting surface.

7. A bag dispenser according to claim 6 , wherein the dispenser support is configured to allow height-adjustability for the frame with respect to the mounting surface.

8. A bag dispenser according to claim 6 , wherein the dispenser support is configured to allow pivotability of the frame with respect to the mounting surface along a plane generally perpendicular to the pivot plane of the brake plate.

9. A bag dispenser according to claim 6 , wherein the dispenser support defines a base and at least one post extending from the base to the frame, the base configured to be mounted to the mounting surface.

10. A bag dispenser according to claim 9 , wherein the dispenser support defines the base, a base post attached to the base, a head post attached to the frame, and an intermediate post extending between the base post and the head post, the intermediate post rotatable with respect to the head post.

11. A bag dispenser according to claim 10 , wherein one of the intermediate post and the head post defines a generally V-shaped self-centering groove configured to receive a spring-loaded pin extending outwardly from the other of the intermediate post and the head post.
