Definitions

  • the present invention relates to a cover for a manhole. More particularly the present invention relates to a cover for a manhole in a ground opening.
  • Manholes are used to permit authorized persons to access underground passageways which contain installations such as electrical and communication lines, natural gas lines, water pipes, sewage systems and the like.
  • a manhole cover is usually placed over the entrance to a manhole and seats in a surrounding frame structure located around an edge of the manhole. In most instances a top surface of the surrounding frame structure and cover lie flush with the surrounding ground surface.
  • the frame structure is usually secured to the edge of the manhole with concrete, asphalt, fasteners or the like.
  • manhole covers are typically made of thick steel and concrete to ensure that they are extremely heavy, and therefore difficult, for the average person to lift. In most cases the sheer weight of the cover is the only form of protection used to prevent unauthorised access. However, covers are sometimes also secured in place by some form of fastener which is operated via a top surface of the cover exterior of the manhole.
  • a cover for mounting on a frame structure associated with a manhole.
  • the frame structure includes side walls defining a central opening there through.
  • the cover includes a cover member dimensioned to fit the central opening with a bottom surface of the cover member facing towards an interior of the manhole and a top surface of the cover member facing away from the manhole.
  • the cover member is moveable with respect to the frame structure between a closed position, whereby the central opening is covered, and an open position.
  • the cover further includes a lock mechanism for releasably locking the cover member in the closed position.
  • the lock mechanism includes one or more locking members engagable with the frame structure to thereby retain the cover in the closed position, and a lock actuator connected to the locking members for engaging and disengaging each locking member with the frame structure.
  • the lock actuator is accessible from the top surface of the cover member.
  • the lock mechanism further includes restraining means for preventing actuation of the locking members by the lock actuator and a release actuator accessible from the bottom surface of the cover member for overriding the restraining means such that the locking members can be disengaged from the frame structure by actuation of the release actuator.
  • the cover is preferably pivotally mounted with respect to the frame structure such that the cover is rotatable between the closed position and the open position.
  • a peripheral edge of the cover member is preferably adjacent to the side walls of the frame structure when the cover member is in the closed position.
  • the lock actuator includes a rotatable member pivotally mounted with respect to the bottom surface of the cover member about a first pivot axis.
  • Each locking member can be engaged and disengaged with an associated aperture in the frame structure by angular movement of the rotatable member.
  • the cover is retained in the closed position when each locking member is engaged in an associated aperture.
  • the apertures are located in the side walls of the frame structure.
  • the release actuator is preferably pivotally mounted to the rotatable member about a second pivot axis and biased towards the bottom surface of the cover member.
  • the rotatable member preferably includes a capturing means for selectively engaging with the restraining means to thereby prevent angular movement of the rotatable member.
  • the restraining means is preferably a bolt such as a barribolt which is beatable in a restraining aperture which extends through the cover member.
  • the barribolt is preferably engageable with the capturing means and release actuator to thereby prevent angular movement of the rotatable member.
  • the capturing means is preferably a notch or cut-out portion in the rotatable member.
  • the release actuator can be pivoted about the second pivot axis in a direction away from the bottom surface of the cover member to thereby disengage the release actuator with the bolt and subsequently permit angular movement of the release actuator and rotatable member about the first pivot axis.
  • the cover further includes at least one seal breaking device for assisting the cover member to move from the closed position when the locking members are disengaged with the frame structure.
  • the seal breaking devices can be mounted on the bottom surface of the cover member and each preferably include a rotatable lug for engaging with the frame structure, and a handle operatively connected to the lug.
  • movement of the handle in a direction away from the bottom surface of the cover member forces the lug into engagement with the frame structure to thereby lever the cover member away from the frame structure.
  • the cover can further include biasing means, in the form of a spring operatively connected to the frame structure for biasing the cover member to approximately a 45 degree angle with respect to the central opening in the frame structure.

  • DESCRIPTION OF PREFERRED EMBODIMENT With reference to the accompanying drawings there is shown a cover assembly for a manhole.
  • the cover assembly includes a frame structure 1 having side walls defining a central opening therethrough.
  • the frame structure 1 being attachable to the manhole.
  • the cover assembly further includes a cover 3 pivotally mounted with respect to the frame structure 1 such that the cover 3 is rotatable between a closed and fully open position.
  • the cover 3 includes a cover member, which is preferably in the form of a cover panel 5, that is planar and dimensioned to fit within the central opening with a bottom surface 7 of the cover panel 5 facing towards the interior of the manhole.
  • the cover panel 5 further includes a top surface 9 which faces away from the manhole.
  • a peripheral edge 11 of the cover panel 5 is adjacent to the side walls of the frame structure 1 when the cover 3 is in a closed position.
  • the cover 3 further includes a lock mechanism for releasably locking the cover 3 in the closed position.
  • the lock mechanism includes one or more locking members 13 which are each preferably in the form of a metal rod.
  • the lock mechanism further includes a lock actuator for moving the locking members 13 into and out of engagement in their associated aperture in the frame structure 1.
  • the lock actuator includes a rotatable member, which is preferably in the form of a turntable 15, that is connected to an end of each locking member 13.
  • the lock actuator further includes a drive member 17 connected to the turntable 15.
  • the drive member 17 of the lock actuator extends through a drive aperture 18 in the cover panel 5 such that the lock actuator is accessible from the top surface 9 of the cover panel 5.
  • the drive member 17 is fixed to the turntable 15 such that rotation of the drive member 17 imparts rotational movement to the turntable 15 about a first pivot axis 20 which corresponds with a longitudinal axis of the drive member 17.
  • rotation of the turntable 15 causes each locking member 13 to move between an extended position, as shown in Figure 4 and a retracted position as shown in Figure 3.
  • the cover 3 is in the closed position, and the locking members 13 are in the extended position, the locking members 13 are engaged in their associated apertures in the frame structure 1.
  • the locking members 13 are in the retracted position, they are disengaged with the apertures in the frame structure 1.
  • the drive member 17 of the lock actuator extends through the drive aperture 18 in the cover panel 5.
  • the drive member 17 is in the form of a bolt having an hexagonal head which can be rotated with an appropriate tool to thereby rotate the drive member 17.
  • the lock mechanism further includes a restraining means 19 for preventing actuation of the locking members 13 by the lock actuator.
  • the restraining means 19 extends through a restraining aperture 21 in the cover panel 5 such that the restraining means 19 can be operated from the top surface 9 of the cover panel 5.
  • the restraining means 19 extends through the restraining aperture 21 in the cover panel 5 into engagement with the turntable 15.
  • the turntable 15 includes a capturing means for engaging with the restraining means 19 to thereby prevent angular movement of the turntable 15 in one direction.
  • the capturing means is preferably in the form of a notch or cut-out portion 23 in a side edge of the turntable 15.
  • the lock mechanism further includes a release actuator 25 which is pivotally mounted to the turntable 15 about a second pivot axis 27 which lies perpendicular to the longitudinal axis of the drive member 17.
  • the release actuator 27 is biased towards the turntable 15 and the bottom surface 7 of the cover panel 5.
  • the restraining means 19 prevents rotation of the turntable 15 in a clockwise and anti-clockwise direction by engaging with both the cut-out portion 23 of the turntable 15 and the release actuator 25.
  • the restraining means 19 is not shown. However, when the restraining means 19 is located in the restraining aperture 21 the turntable 15 will be prevented from moving in a clockwise or first direction due to the engagement of the restraining means 19 with the cut-out portion 23. Similarly, an attempt to move the turntable 15 in an anti-clockwise or second direction will result in the restraining means 19 engaging with the release actuator 25.
  • the release actuator 25 can be pivoted about the second pivot axis 27 in a direction away from the bottom surface 7 of the cover panel 5.
  • the restraining means 19 is shown positioned between the notch 23 of the turntable 15 and the release actuator 25. In this position, the turntable 15 and release actuator 25 are not able to be rotated about the first pivot axis 20.
  • the release actuator 25 is shown in a position whereby the release actuator 25 has been pivoted about the second pivot axis 27 away from the bottom surface 7 of the cover panel 5 such that the release actuator 25 is clear of an end of the restraining means 19.
  • the cover 3 further includes a one or more seal breaking devices 29 for assisting the cover 3 to move away from the closed position when the locking members 13 are in the retracted position and thereby disengaged with the frame structure 1.
  • the seal breaking devices 29 can be located at various locations around the peripheral edge 11 of the cover panel 5 on the bottom surface 7 of the cover panel 5.
  • Each seal breaking device 29 includes a rotatable lug 31 and a handle 33 operably connected to the rotatable lug 31.
  • the rotatable lug 31 of the seal breaking device 29 is in a position such that is does not inhibit the cover 3 from being in a fully closed position.
  • the cover 3 may further include a biasing means in the form of a spring 37, as shown in Figures 3 and 4, operatively connected to the frame structure 1.
  • the spring- 37 biases the cover panel 5 to a partially open position, as shown in Figure 1 , whereby the cover panel 5 is approximately at a 45 degree angle with respect to the central opening in the frame structure 1.
  • the cover panel 5 can then be manually pushed to a fully open position such that the cover panel 5 is approximately at a 90 degree or more angle with respect to the central opening in the frame structure 1.
  • the cover 3 further includes a lift arm 39 which operatively connects the cover panel 5 to the spring 37.
  • the lift arm 39 includes a grab handle 41 which can be grasped when opening and closing the cover 3.
  • the restraining means 19 includes a keyed lock 35 which is operated to release the restraining means 19 from the restraining aperture 21.
  • the restraining means 19 could instead be in the form of a bolt such as a barribolt which is threaded into the restraining aperture 21 and is removable by the insertion of a suitable tool into the restraining aperture 21 to thereby enable rotation of the bolt and subsequent removal from the restraining aperture 21.
  • the turntable 15 is then free to rotate upon rotation of the drive member 17.

  • the cover 3 can be manually lifted and forced out of the closed position.
  • the top surface 9 of the cover panel 5 can be provided with a threaded bore 43 into which a tool may be threaded. The tool can then be forcefully pulled until the cover panel 5 is freed.
  • an end of the restraining means 19 either includes a keyed lock 35 or a suitably shaped bolt end which can only be rotated with a specific tool which only authorised personnel have access to.
  • the cover 3 is securely locked in the closed position.
  • the protective caps 43 can then be put in place over the apertures 18, 21 and 43.
