Abstract: A side-load connector comprises a housing, a port into which an attachment post of a retractor blade is loaded, a sidewall opening, a retaining fork between a housing upper surface and a housing lower surface, and a slider. The port passes through the housing upper surface and the housing lower surface. The sidewall opening passes through a housing sidewall and permits lateral passage of the attachment post through the housing sidewall to the port. The retaining fork includes a front tine and a back tine. The slider is coupled to the retaining fork and configured to slide the retaining fork between a closed position in which the front tine and the back tine engage the loaded attachment post and an opened position in which the front tine does not engage the loaded attachment post.

Abstract: An erosion control apparatus includes a mat. The mat includes a top side, a bottom side, a first lateral edge, a second lateral edge opposite the first lateral edge, a first longitudinal edge and a second longitudinal edge opposite the first longitudinal edge. The first lateral edge is folded under the bottom side of the mat to form a first lateral pocket. The second lateral edge is folded under the bottom side of the mat to form a second lateral pocket. The mat may be anchored to a ground surface so as to trap sediment in the first and second lateral pockets and between a bottom side of the mat and the ground surface.

Abstract: An erosion control apparatus includes a flexible, container and a cord. The container includes a container upper side, a container lower side opposite the container upper side, a container trailing end, a container leading end opposite the container trailing end, and a container mouth toward the container leading end. The container mouth provides an opening to a container interior. The cord is attached between the container mouth and an attachment point toward the container trailing end. The cord draws the container mouth toward the container trailing end due to a length of the cord between the container mouth and the attachment point being shorter than a length of the container between the container mouth and the attachment point. The cord further draws the container mouth toward a closed position as sediment enters the container mouth, fills the container interior, and urges the container leading end away from the attachment point.

Abstract: A retractor system includes a retractor blade and a retractor arm having a side-load connector. The side-load connector includes a port that passes through an upper surface and a lower surface of the side-load connector. A sidewall opening in the side-load connector permits lateral passage of the attachment post through a sidewall to the port. The side-load connector includes a cam pivotably coupled between the lower surface and the upper surface and a spring that applies a biasing force on the cam. The biasing force biases the cam to a closed position in which the cam extends into the opening and prevents unloading the attachment post from the port via the opening. The cam selectively engages either a first groove or a second groove of the attachment post sidewall. The side-load connector further includes teeth that engage teeth of the retractor body when the cam engages the first groove.

Abstract: A retractor system includes a frame and first and second retractor blades. The frame includes first and second securement features. At least one of the first and second securement features is movable with respect to the frame when the first and second securement features is mounted to the frame. Proximal portions of the first and second refractor blades are secured proximate the first and second securement features respectively. In a first position the first and second refractor blades are laterally opposed. Movement of the securement feature adjusts the angle of at least one of the retractor blades so that at least one of the retractor blades may be adjusted between an acute angle and an obtuse angle to horizontal.
