Abstract: A restraint for use in restraining cargo includes a main body having an elongated shape with a contact end configured to contact and restrain the cargo and a second end opposite the contact end, the contact end defining a first face and a second face such that a first angle between the first face and the second face is at least one of less than or equal to 160 degrees. The restraint further includes a spring configured to allow the main body to rotate relative to a stationary object in response to contact with the cargo and to cause the main body to return to a neutral position in response to a lack of contact with the cargo.

Abstract: An actuation assembly that uses a magnetic field to dispose/retain a first part in a home position is disclosed. An actuation force may be exerted on the first part to move the first part from a home position to an actuated position. A biasing member of the actuation assembly may be used to move the first part from its actuated position back to its home position. The magnetic field may be used to reduce the amount of overtravel of the first part as it is moved back to its home position by the biasing member, may be used to retain the first part in this home position, and/or may be used to establish the home position.

Abstract: An installation tool for tree steps is disclosed allowing for one-handed operation through inserting the tool onto the tree step in either a perpendicular or parallel orientation to the tree step, with the orientation of the tree step to the tool chosen based on the amount of torque desired when installing and removing a tree step. The tool is placed onto the tree step in a parallel orientation by placing the platform portion of the tree step inside the tool's central cylindrical cavity. The tool is placed onto the tree step in a perpendicular orientation by placing the platform portion of the tree step inside the tool's slot-and-lock system and securing the lever portion of the tree step against one of the slots using a groove cut into the tool's main body. This perpendicular orientation effectively extends the lever portion of the tree step and provides additional leverage to the user.

Abstract: A safety knife may include a housing defining an internal cavity, a blade coupled to the housing, and a sheath slideably engaged with the housing. The sheath may translate into the internal cavity of the housing to expose the blade. A switch may be pivotally coupled to the housing and may release the sheath from a locked position in response to depression of the switch. A locking arm may be pivotally coupled to the sheath with a projection that locks the sheath in an extended position by engaging an internal wall of the housing. A pawl may be pivotally coupled to the switch to depress the locking arm. The sheath includes a ridge that engages the pawl and rotates the pawl from a fully extended position.
