A control system for a loading dock includes: a controller operatively connected to control loading dock equipment; sensors operatively connected to the controller; output devices operatively connected to the controller and configured to provide a visual output; input devices operatively connected to the controller and configured allow a user to enter inputs into the controller; wherein the controller is configured to display data received from at least three of the sensors on at least one display screen and allow a user to control at least three of the pieces of loading dock equipment via at least two of the input devices. Some embodiments include a method of controlling loading dock equipment.

A dock leveler for a loading dock. In some embodiments, the dock leveler may include a bridge assembly including a deck and a lip extendable from the deck, where the lip is pivotally movable between a stowed position and an extended position. The dock leveler may also include a frame supporting the bridge assembly. The dock leveler may also include a beam and a lip keeper. The beam may include a first end positioned proximate a front edge of the dock. The lip keeper assembly may be configured to selectively secure the lip in the stow position. The lip keeper assembly may be adjustably coupled to the beam permitting adjustment relative to the beam toward or away from the front edge of the dock.

A dock leveler for a loading dock. In some embodiments, the dock leveler may include a plurality of legs, a horizontally extending lower bracket coupled to a bottom region of each leg of the plurality of legs, a horizontally extending upper bracket coupled to an upper region of each leg of the plurality of legs, and a pivot boss coupled to the lower bracket. The pivot boss may include a first mounting plate coupled to the adjustment bracket and a first hole and a pivot rod for pivotable attachment to at least one of a lower arm and an upper arm of a lift arm assembly.

A dock leveler that fits within the pit of a loading dock. The dock leveler may have a rear leg bracket including a plurality of legs. The legs may be couplable to a bottom surface of the leg bracket and to a rear wall of the pit and may have a bottom portion attached to the bottom surface of the pit. The dock leveler may have a deck with a rear portion disposed adjacent the rear wall and supported by the rear leg bracket. The deck may be horizontal when in a stowed position. The dock leveler may also include a lift arm assembly extending from the bottom surface of the deck to the bottom surface of the pit and moveable along the bottom surface of the pit. The lift arm assembly may have a bottom portion movable independent of structure at the bottom portion of the plurality of legs.

A flexible seal may be attachable to a moveable barrier and usable to seal selectively along a horizontal lower surface adjacent the moveable barrier and along a vertical upper surface adjacent the moveable barrier. The flexible seal may assume a first orientation to be affixed to a lower edge of the movable barrier and may assume a second orientation to be affixed to an upper edge of the movable barrier. In the first orientation, a central region of the flexible seal contacts the horizonal lower surface. In the second orientation, a first or second end of the flexible seal contacts the vertical upper surface.

A door handle system is described. The door handle system includes: a door handle having: a lower grip portion an upper actuation portion; an angled projection located on the upper actuation portion; handle attaching structure, and a door plate having: attaching structure configured to allow the door plate to attach to a door; door plate attaching structure for interfacing with the handle attaching structure for allowing the handle to pivotally attach to the door plate; a front face; and channel defining structure in the front face defining a channel in the front face for allowing clearance for the angled projection to extend through the front face into the channel and move in the channel when the door handle is pivoted with respect to the door plate. A method of keeping elongated members from being retained by a door handle system is also described.

A roller bracket assembly for a movable barrier includes a base bracket coupled to the movable barrier and a roller holder bracket. The roller holder bracket is rotatably coupled to the base bracket. The roller bracket assembly further includes a support bracket. The roller holder bracket includes multiple ratcheting features configured to engage with corresponding ratcheting features of the support bracket. The ratcheting features of the roller holder bracket and the support bracket allow movement of the roller holder bracket away from the movable barrier rotating relative to the base bracket, but prevent movement of the roller holder bracket toward the movable barrier.

A stabilization roller bracket is positioned adjacent to a hinge and supplements a hinge in coupling a roller to a movable barrier. The stabilization roller bracket includes a base configured to be coupled to an inner surface of the movable barrier. The base includes a main body and a frangible portion. The stabilization roller bracket also includes at least one wall extending from the base and including a plurality of stem-receiving holes, each of the plurality of stem-receiving holes spaced a different distance from the base and configured to receive a portion of a stem of a roller for the movable barrier and space the roller from the inner surface of the movable barrier.

A louver system for a panel of a movable barrier may include a first louver carried on the panel of the movable barrier and including a first slat portion and a first pivot base. A second louver may be carried on the panel of the movable barrier and offset from the first louver, the second louver including a second slat portion and a second pivot base. A gear train may be coupled to the first pivot base and the second pivot base. The gear train may be configured to simultaneously rotate the first louver and the second louver between an open configuration and a closed configuration. A motor may be carried on the movable barrier and configured to drive the gear train to simultaneously rotate the first louver and the second louver.

A frame rail for a movable barrier comprises an outer surface portion and an inner surface portion, the inner surface portion forming an internal cavity. The frame rail also comprises a first module connector formed in the internal cavity, the first module connector extending along a length of the frame rail and configured to slidably receive a corresponding second module connector of an internal module.
