摘要： A selectively adjustable and lockable utility mount is used to mount a device to a stable structure. The utility mount includes a hydraulic lock that applies the locking force that maintains the locked condition of the utility mount. Mounting brackets for utility mounts have spaced-apart mount elements that engage a surface of a stable structure. Some configurations of mounting bracket include mount elements that are movable between stored conditions and deployed conditions. The stored conditions reduce the size of the device to make it more convenient to pack. A climbing stick uses the storable mount elements.

摘要： Systems and methods for securing a ladder to a gutter are disclosed. An insert includes a first portion configured to fit within an opening for the gutter and a second portion configured to form a channel configured to receive a front surface of the gutter. A number of arms extend from the second portion. The arms are selectively deformable into a number of positions, and may be wrapped around side rails of the ladder.

摘要： The present invention relates to at least a foldable step. The step features an upper and a lower step supported by a structure including a right side each having a vertical support member, an angled support member, and upper and lower step support members. A horizontal front support member provides support for the lower step. Left and right diagonal support members are slidably coupled to the upper step support members. A rear horizontal support member and optional diagonal members provide additional support to the upper step. The step is foldable into a folded position, by folding both the upper and lower steps upwardly. The step has a minimal profile in the folded position.

摘要： A ladder assembly is provided, including the following: a mounting plate that connects to a side surface of a module in a fabrication facility; a step ladder, including, a ladder frame having an arm that connects to the mounting plate at a first joint, wherein the step ladder rotates about the first joint between a lowered position and a raised position, the lowered positioned defined by resting of the step ladder on a floor of the fabrication facility, and the raised position defined by suspension of the step ladder off of the floor and substantially over the module; a plurality of step plates connected to the ladder frame, the step plates defining step surfaces for a user when the step ladder is in the lowered position. A sleeve extends below one of the step plates of the step ladder, to house electronic equipment used in the fabrication facility.

摘要： A portable multi-use platform that is capable of providing 360 degree views for multiple persons safely and securely without interfering with each individuals comfort space. The platform can be easily set up and taken down and transported to different locations using a detachable wheeled frame assembly. The applications of this platform are not limited solely to hunting but can be used in numerous activities such as “zip-line” type sports, photography and video applications, utility pole climbing professions, as well as military and police operations. This platform solves the problem of partial views, limited occupants, and the transportation over terrain to and from site. It also addresses the issue of attaching to a plurality of various tree sizes with a sliding floor attachment system as well as a possible problem of tree lean and leveling with the use of a sliding “biter” system.

摘要： A swiveling staircase is provided for access to a device disposed above the ground at a distance that a person of an ordinary height is not able to reach. The staircase includes an immobile upright stanchion and a staircase assembly pivotally coupled to the stanchion. The staircase assembly includes a platform on the top of a plurality of stairs. The staircase assembly rotates between a first position where the staircase is docked out of way for storage and a second position where the staircase assembly is facing the front side of the device so that an operator standing on the platform may be able to reach the device.
