摘要： 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).

摘要： 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.

摘要： The safety device is to be installed in a well. The safety device is has a support structure that is arranged to be lowered at least partly into the well and that restricts the movement of the safety device in the horizontal direction. A collar is in connection with the support structure and arranged to be set against the ground to restrict the movement of the safety device in the vertical direction, with a protective structure arranged on the collar to define a safe working area around the well.

摘要： The invention relates to a support structure of a cover of a structure capable of being inserted into the ground, for example of a shaft or a channel, wherein the cover (10) comprises a traversable surface (11) and the support structure (20) extends downwards under said cover into the structure and comprises beam-shaped supports (21-23) such that their under support side (24) facing away from the surface (11) experiences a tensile stress when the surface (11) is loaded. The invention is further characterized in that between two areas (A, A′) a thickness (D) of the carriers with minimum tensile stress is configured substantially symmetrically in an increasing manner up to a maximum value and then, in turn, in a decreasing manner to form a ball shape when viewing the cover from below.

摘要： Embodiments of a manhole cover safety apparatus having a circular base defining a central opening and a flange that extends outwardly from the circular base. An expandable cover is in rotatable engagement with the flange through a plurality of frame members that are secured to a cover portion which is operable between a deployed position wherein the cover portion covers at least a portion of the circular opening to provide a visual and physical warning of an uncovered manhole and a retracted position wherein the cover portion does not cover the central opening.

摘要： Coverings for structures which can be installed in the ground are known. For example, these are drainage channels or manholes.

摘要： An apparatus for locking an enclosure cover, such as a manhole cover or enclosure lid, in seated engagement on its enclosure frame, includes a lock housing positioned within a lock aperture extending perpendicularly through the top surface of the enclosure cover. A reciprocating, manual throw bolt is inserted within an aperture extending laterally within the enclosure cover between the lock aperture and the side of the enclosure cover for releasable engagement into a receiving aperture within the enclosure frame. When inserted, the lock housing maintains the manual throw bolt in locking engagement with the enclosure frame. The lock housing includes a cylinder cam lock for releasably locking the lock housing in place within the lock aperture. The cylinder cam lock uses conventional keys that can be mastered or zoned. The locking apparatus can be retrofit into existing enclosure covers or included during initial manufacture of such covers.
