A controlled pressure release vault panel assembly is capable of functioning as a second, or auxiliary, relief port to allow the escape of fluid from the vault in the event of pressure build-up inside the vault or in an explosion event. The vault panel assembly may define an opening that includes a manhole cover assembly. The manhole cover assembly may also be vented, and may function as a primary vent. The vault panel assembly may include a retention assembly extending from the vault panel underneath a portion of the vault, enabling a limited range of motion of the vault panel for the escape of fluid and allowing the reseating of the vault pane on the vault once the pressure inside the vault approaches ambient pressures.

Explosion mitigating vault

A manhole cover assembly configured to behave as a relief valve in an explosion event, opening so that fluid, such as air or explosive gas, may vent from an underground area. The manhole cover assembly may include a manhole cover and a frame, and may be configured to limit movement of the manhole cover with respect to the frame in response to increased pressure on the manhole cover. In one embodiment, the manhole cover may include legs that are configured to enable a range of movement of a portion of the cover such that the cover can be unseated at an angle with respect to the frame to allow fluids to escape from the underground area.

Explosion mitigating cover

A manhole cover assembly configured to behave as a relief valve in an explosion event, opening so that fluid, such as air or explosive gas, may vent from an underground area. The manhole cover assembly may include a manhole cover and a frame, and may be configured to limit movement of the manhole cover with respect to the frame in response to increased pressure on the manhole cover. In one embodiment, the manhole cover may include legs having angled surfaces adapted to substantially center or guide the manhole cover in the frame while the manhole cover displaces to release pressure. In another embodiment, one or more legs slidable within the manhole cover to enable configuring the manhole cover between a restraint mode and a removal mode.

A manhole cover includes a cover panel formed from a first material, which may be a generally lightweight material, and an insert formed within a cutout in the first material. The insert may be formed from a higher strength material and may include one or more openings for receiving conventional cover removal tools. In one embodiment, the manhole cover includes a cover panel having a peripheral edge and defining a diameter, and further defining an opening or cutout that is spaced from the peripheral edge. The insert is disposed in the opening. The insert may include an upper surface and a lower surface opposite the upper surface, the insert defining first and second openings in the upper surface, with the first opening shaped to receive a first removal tool and the second opening shaped to receive a second removal tool.

The manhole cover assembly may include a manhole cover and a frame, and may be configured to limit movement of the manhole cover with respect to the frame in response to increased pressure on the manhole cover. In one embodiment, the manhole cover may include legs having angled surfaces adapted to substantially center or guide the manhole cover in the frame while the manhole cover displaces to release pressure. In another embodiment, one or more legs may be at least one of pivotable with respect to the manhole cover and slidable within the manhole cover to enable configuring the manhole cover between a restraint mode and a removal mode.

An adjustable pedal includes a first member with a slot and a second member movable along the slot relative to the first member. A pin is disposed in the slot. A biasing member urges the second member toward the one end. A tension control member is connected to the pin to selectively adjust the second member. The tension control member has a secondary lock member. To prevent movement of the second member relative to the first member in one condition and permit movement of the second member relative to the first member in another condition. An actuation system employing a cable is disclosed.

Cable actuated adjustable pedal

An adjustable control pedal for a motor vehicle includes a pivotable upper pedal arm having a slot formed therein, a link pivotable relative to the upper pedal arm, and a lower pedal arm having an upper end pivotably connected to the link and a lower end carrying a pedal. A nut is pivotally connected to the link such that the link pivots relative to the upper pedal arm upon movement of the nut along a drive screw. A pin is connected to the lower pedal arm and laterally extends into the slot such that the pin moves along the slot upon pivotal movement of the link. Also disclosed is a control pedal having a drive block or a pair of spaced apart pins located in a single slot of the upper pedal arm.

Adjustable brake, clutch and accelerator pedals

An adjustable control pedal for a motor vehicle includes a first member having a slot formed therein, a pin laterally extending into the slot and having an abutment facing the first member on a side of the first member opposite the second member, and a second member rigidly secured to the pin and movable relative to the first member along the slot. A plastic bushing encircles the pin and extends into the slot. The bushing has a flange engaging the first member on a side of the first member opposite the second member. A plastic washer encircles the pin and is located between the first and second members. A spring washer such as a wave or Belleville washer is located between the abutment and the flange and resiliently biases the second member relative to the first member to resist relative lateral movement between the first and second members to reduce lash therebetween. The pin can be ether a guide pin or a drive pin of the control pedal. Various embodiments are disclosed wherein the first and second members are upper and lower pedal arms respectively and are a mounting bracket and an upper pedal arm respectively.

An adjustable control pedal for a motor vehicle includes a pivotable upper pedal arm having an arcuate slot formed therein, a link pivotable relative to the upper pedal arm, and a lower pedal arm having an upper end pivotably connected to the link and a lower end carrying a pedal. A drive assembly includes a screw supported by the upper pedal arm, a motor operatively connected to the screw to selectively rotate the screw, and a nut threadably engaging the screw and adapted to move along the screw upon rotation of the screw. The nut is pivotally connected to the link such that the link pivots relative to the upper pedal arm upon movement of the nut along the screw. A pin connected to the lower pedal arm and laterally extends into the slot such that the pin moves along the slot upon pivotal movement of the link.

An adjustable control pedal for a motor vehicle includes a link having an inclined slot formed therein, a screw supported by the link, a motor operatively connected to the screw to selectively rotate the screw about a central axis, and a nut threadably engaging the screw and adapted to move axially along the screw upon rotation of the screw. A pedal aim includes upper and lower pedal arms operatively connected for extension and retraction of the lower pedal arm relative to the upper pedal arm. The upper pedal arm is pivotally connected relative to the link. The lower pedal arm has a pedal at a lower end and a pin extending into the inclined slot. The pin is operatively connected to the nut so that the pin moves along the slot as the nut travels along the screw. The pedal arm rotates relative to the link and the lower pedal arm extends or retracts relative to the upper pedal arm as the pin moves along the inclined slot such that the pedal moves along a generally linear and horizontal path upon rotation of the screw. A second embodiment of the invention is disclosed which includes a link having first and second arcuate and inclined slots formed therein. A one-piece pedal arm is operatively connected to the nut. The pedal arm has a pedal at a lower end and first and second pins extending into the first and second inclined slots respectively so that the first and second pins move along the first and second slots respectively as the nut travels along the screw. The pedal arm rotates relative to the link as the first and second pins move along the first and second slots respectively such that the pedal moves along a generally linear and horizontal path upon rotation of the screw.
