A ladder is provided having a base section and a fly section slidably coupled with the base section. The base section includes a first pair of spaced apart rails and a first plurality of rungs extending between and coupled to the first pair of spaced apart rails. The fly section includes a second pair of spaced apart rails and a second plurality of rungs extending between and coupled to the second pair of spaced apart rails. The various rungs may be coupled with their associated rails in an offset relationship such that they are not centered along a longitudinal center axis line of the rails. A rung lock device may be used which includes an arm pivotally coupled with the base section and configured to selectively engage various rungs of the second plurality of rungs to maintain the fly section in a desired position relative to the base section.

Extension ladder, ladder components and related methods

Ladders, ladder components and related methods are provided. In some embodiments, adjustable stepladders are provided which include locking mechanisms that enable height adjustment of the ladder through application of a force towards the rails of the ladder. The locking mechanism may include a base or bracket, a handle or lever pivotally coupled with the bracket, an engagement pin coupled with the lever, a biasing member to bias the handle towards a first position relative to the bracket, and a detent mechanism for retaining the lever in at least a second position relative to the bracket.

Adjustment mechanisms, ladders incorporating same and related methods

An electronic lock includes a lock body and a shackle selectively securable via one or more ball bearings. An asymmetric cam can be rotated by a key or an electric motor to: a locked state in which the ball bearing secures the shackle within the lock body via at least one lock notch in the shackle, an unlocked state in which the ball bearing is released from the lock notch to unlock the shackle and subsequently engages a revolved notch on a distal end of the shackle to prevent removal of the shackle from the lock body, and a removal state in which the ball bearing is released from the lock notch and the revolved notch to allow the shackle to be removed from the lock body. A shackle detector can detect a shackle in the locked state. Externally accessible electrical contacts allow for jumpstarting a discharged battery.

Electronic lock and interchangeable shackles

A wireless, electronic interchangeable locking core that includes an outer housing and a locking core that is rotatable via an external handle between a locked position and an unlocked position. The handle is prevented from rotating the locking core unless wirelessly-provided authorization credentials are validated and/or a pattern of physical input interactions with an electronic sensor is matched with a stored pattern. The pattern may be defined, for example, as a sequence of short and long interactions with a button, light sensor, touch panel, or the like. The electronic interchangeable locking core may include a battery and be configured for installation in small format interchangeable core (SFIC) housings.

Wireless-enabled interchangeable locking core

A ladder is provided having a securing apparatus for securing the ladder to a horizontally extending support structure (e.g., a utility cable), a vertically extending support structure (e.g., a utility pole) or both. In accordance with one embodiment, the securing apparatus includes a pair of spaced apart engagement mechanisms, wherein each engagement mechanism is pivotally coupled with an associated rail of the ladder. Each engagement mechanism includes a frame member, an engagement member pivotally coupled with the frame member and a pole grasping structure coupled with the frame member. In one embodiment, each engagement member is configured to rotate from a first position, wherein an open gate is formed between the engagement member and its associated frame member, to a closed position.

An apparatus, system, and means are disclosed for a modular backpressure sensor configured for use with a fluid delivery nozzle. The modular backpressure sensor may be installed and removed using simple tools and may optionally include an activator handle attachment. The system may optionally include a protective end plug for the fluid delivery nozzle.

Apparatus, system, and means for a modular backpressure sensor

A variable control valve for a gas compression system is disclosed for a gas compressor with a piston having a variable displacement within a compression chamber of the gas compressor. A pressure within a crankcase chamber of the gas compressor acts upon the piston A diaphragm within the control valve, controls a flow of high and low pressure gas into and out of the pressure chamber, thus controlling the displacement of the piston. The diaphragm is acted upon by a predetermined reference pressure within a reference chamber of the control valve. The predetermined reference pressure within the reference chamber is created by a flow into and out of the reference chamber of the high and low pressure gas. The predetermined reference pressure can be changed in order to optimize compressor output. This flow is controlled by reference chamber valve means ( ) operably coupled to the reference chamber, the reference chamber valve means being responsive to electrical signals.
