Improved quick opening closures are disclosed. The closures may include a hub and a door hingedly attached to the hub by hinge arms. A seal is disposed around the door. The hinge arms may be mounted to door blocks that are attached to and substantially centered on the door. At least one support post may be connected between the hinge arms. An activation bar may be pivotally connected to a support post, such as with a pivot bracket. The activation bar is used to evenly apply closing force to the door through the centralized hinge blocks to evenly compress the seal between the door and the hub. The activation bar may also be used to pull the door out of engagement with the hub toward its open position. Various devices may connect a distal end of the activation bar to the hub to assist in opening / closing the door.

The utility model relates to a steel double-leaf flood-proof door which comprises a door frame, door leaves, an upper bolt clamping mechanism and a lower bolt clamping mechanism, the upper bolt clamping mechanism and the lower bolt clamping mechanism are arranged on the door leaves, a lower doorsill of the door frame is buried in a terrace, and the upper surface of the door frame is flush with the terrace; the upper part of the lower doorsill is provided with a plurality of openings for inserting bolts; the upper and lower bolt clamping mechanism comprises a bolt, a movable sinking water retaining block which moves up and down synchronously with the bolt is fixedly arranged on the bolt, the movable sinking water retaining block is in an L shape, the bottom face of the movable sinking water retaining block can cover the upper surface of the lower doorsill, and a rubber sealing piece is arranged on the side face of the movable sinking water retaining block to be attached to the door leaf. The lower doorsill is pre-buried in the terrace and kept on the terrace, when the plug pin is downwards inserted into the lower doorsill, the L-shaped movable sinking water retaining block moves downwards together, the bottom face of the L-shaped movable sinking water retaining block presses the lower doorsill, meanwhile, the side face of the L-shaped movable sinking water retaining block blocks a door crack in the bottom of the door leaf, and the good sealing and flood preventing functions are achieved.

A door is configured to be coupled to a merchandiser. The door includes a first opaque panel and a second opaque panel coupled to the first opaque panel. The first and second opaque panels define a cavity therebetween. The door also includes a hinge coupled to at least one of the first opaque panel or the second opaque panel, a stiffener positioned in the cavity and in contact with the first and second opaque panels, and an insulative material disposed within the cavity and configured to bond to one or both of the first opaque panel and the second opaque panel to form a rigid door. The hinge is configured to pivotably couple the door to the merchandiser.

To provide an opening device with excellent water-proofness.SOLUTION: An opening device includes a lower frame 1 and a vertical frame 2, the lower frame 1 having a horizontal tension material 3 in the longitudinal direction, the vertical frame 2 having a vertical tension material 4 in the longitudinal direction, the vertical tension material 4 having a fin piece 6 extending from the tip of the inner side wall 5 located closer to the inner periphery to the outer periphery, the inner side wall 5 being inclined towards the inner periphery, the horizontal tension material 3 having a fin piece 6 extending from the tip of the inner side wall 5 located closer to the inner periphery to the outer periphery, a water-stop material 7 being provided on the inner side surface of the longitudinal end, and the lower end of the vertical tension material 4 abutting against the water-stop material 7.SELECTED DRAWING: Figure 1
