A molded access door assembly for an access opening in a wall or ceiling is provided. It includes a molded frame with a frame channel forming the outside of the access door assembly. The frame channel has spaced apart exterior and interior walls joined at the top edge by a top wall and a lip extending from the bottom edge of the inner wall into the interior of the molded access door assembly to define an opening. The lip provides a stop rest for the door in the closed position so that the door is capable of being attached to the wall or ceiling. The assembly also includes a door having a top surface and a first part of a hinge assembly along one edge of the top surface which cooperates with a matching second part of the hinge assembly along one edge of the frame channel to allow the door to move between an open and a closed position.

In an example, a retainer may include a first latch, a plunger, a second latch, and a linkage engaging the second latch with the first latch. The plunger may actuate the first latch, and the linkage may actuate the second latch upon the first latch being actuated.

A molded access door assembly for an access opening in a covering material of a wall or ceiling is disclosed. The door assembly includes a frame defining a frame opening. The frame is positionable against the covering material with the frame opening in alignment with the access opening. The frame includes a lip extending about a perimeter of the frame opening for bearing against the covering material adjacent the access opening, and a plurality of fastener holes passing through the lip for receiving fasteners to secure the frame against the covering material. The door assembly further includes a molded door hingedly connected to the frame. The door is movable between an open position providing access to the frame opening and the fastener holes, and a closed position in which the door covers the frame opening and an entirety of the fastener holes.

A watertight cap used with an electronic apparatus is provided with a cap body to be set in an installing recess of the apparatus case of the electronic apparatus, an insertion part provided on the cap body and inserted into a through hole formed in the installing recess, a watertight projection provided on the peripheral surface of the insertion part to be resiliently pressed against the surface defining the through hole, a reinforce member embedded in the cap body and the insertion part for preventing the insertion part from deforming inwards, and a hook part provided on the insertion part so as to project into the apparatus case to engage with the stopping part in the through hole, when the insertion part is inserted in the through hole, thereby securing enhanced watertight of the apparatus case and preventing the cap body from slipping out from the apparatus case accidentally.

A breakaway gate assembly includes a hinge subassembly rotatably mounted to a vertical hinge post, and a gate subassembly removably mounted to the hinge subassembly. The gate subassembly includes a gate body and a plurality of standoff features coupled thereto. The hinge subassembly comprises a vertical mounting plate forming a plurality of apertures configured to receive and secure a respective plurality of standoff features. Each of the plurality of apertures comprises a wide portion for receiving a head portion of one of the standoff features, and a narrow portion below the wide portion for receiving a stem portion of a respective standoff feature to position a portion of the vertical mounting plate between the vertical mounting surface and the respective bearing surface. The hinge subassembly also comprises a plurality of hinge rings coupled to the first plate surface, the plurality of hinge rings rotatably disposed around the vertical hinge post.

Coverings for structures which can be installed in the ground are known. In order to lock the covering on the structure, closures are known which comprise a snap bolt which is designed in such a way and is mounted movably on the covering (20) against the force of a spring device in such a way that, during closing of the covering (20), the snap bolt is forced back and snaps in behind a counterbearing (14, 14) fixed to the structure in a closure position. To simplify the arrangement and also to improve durability, it is proposed that the snap bolt is mounted in a housing (40) which can be fastened in a housing receptacle of the covering (20).

The present invention relates to a secure barrier for an underground valve box. The device may have a bolt and a nut for adjusting the length of the bolt to position curved plates to press against the inner circumference of a cylindrical valve box. The bolt housing may include a flange that protrudes through a slot in a horizontal metal plate. The plate may have handles for ease of lifting and replacement of the plate. The protruding flange may feature a hole for insertion of a padlock. When the padlock is secured, the plate cannot be removed from the cylindrical valve box as the adjustable bolt housing cannot move sufficiently to retract the curved plates from the inner cylindrical surface of the valve box. Thus, only authorized personnel with the proper padlock key or combination can operate the valve, deterring vandals.
