A tree stick mount attachment assembly includes a tree stick body. A panel has a front side, a back side, and a perimeter edge extending between the front and back sides. The backs side faces and is attached to the tree stick body. The perimeter edge has a plurality of slots therein and each of the slots extends through the front and back sides. The slots removably receive a tether extending around the tree to retain the tree stick body on the tree. The tether is attached to the tree stick body and extended around the tree. Thereafter, the tether is then extended into the slots to secure the tree stick body to the tree.

A system for a climbing apparatus including a housing assembly, a wheel assembly, a lock assembly, a rope assembly and a chainsaw assembly is disclosed. The housing assembly includes a housing having a rope wheel therein. The housing is mounted to a chainsaw to power the components within the housing to allow a user to ascend and descend a structure. The rope is secured to the top of a structure and then mounted to the rope wheel at an opposite end. The chainsaw is actuated to also actuate rope assembly. The rope wheel rotates to allow for rope to be fed, allowing a user attached to the housing to ascend or descend, as needed. With the lever the user may lock the rope in place to allow the user to work at a desired height on a structure.

A combination climbing apparatus (1) comprising or including a rope ascender (5) and a pulley block (6), the rope ascender having front (19) and rear (21) plates disposed in generally parallel relationship, a first swivel pin (11) being received within co-axial bores in the front and rear plates, about which pin the plates are swivelable with respect to each other, a cam lever (9) mounted on the first swivel pin between the front and rear plates, the cam lever being connected, directly or indirectly, to a climbing rope braking surface (10) on a cam between the front and rear plates, the cam lever being operable to trap the rope against the cam braking surface, the front and rear plates each including a second bore (22,23) remote from the major axis of the first swivel pin for receiving a second, removable, swivel pin (29), a pulley block releasably the ascender and pulley block may be selectively used in combination when required or separately when not. The invention also extends in a second aspect to a pulley block for use in a combination climbing apparatus according to the first aspect of the invention, or separately.

A climbing apparatus includes a mast having a plurality of mast segments operable to vertically stack one after another. Each segment includes a stand-off to abut against a climbing object and form a space for receiving a strap to secure the mast to the climbing object. The apparatus includes a platform assembly having a (i) a platform, (ii) a seat spaced apart from the platform, and (iii) a frame connecting the seat to the platform. An upper trolley is provided for independent mobility up and down along the mast. The upper trolley includes a first brake connected to a handle operable to actuate movement of the trolley. A lower trolley is provided and is operable for independent mobility up and down along the mast relative to the upper trolley. The lower trolley includes a second brake and is connected to the frame of the platform assembly.

Disclosed is a pulley assembly in a roped access system including first and second plates and a sheave carried for rotation about an axis normal to the plates. An aperture passes through each plate parallel to the axis. The plates have a closed condition when the apertures are coaxial with one another and the plates are in contact near the apertures, forming a rope passage extending between the plates adjacent the sheave, having an upper part smaller than parts of the passage below that upper part. A roped access system includes a climbing rope passing through the rope passage and a tether connected to the climbing rope above the pulley assembly by a friction hitch and an aperture of the pulley assembly, the hitch. The hitch grips the rope upon downward force to the tether, releasing its grip upon upward force to the friction hitch by pulley assembly plates.

An apparatus includes at least one supernumerary artificial limb and a base structure configured to couple with a human body. The base structure includes a sensor that obtains a measurement regarding load of the human body. The proximal end of the supernumerary artificial limb is coupled to the base structure. The apparatus further includes a processor operatively coupled with the sensor and configured to receive the measurement from the sensor. The processor is also configured to generate a control signal to change at least one of a position of the supernumerary artificial limb and a torque exerted by the supernumerary artificial limb based on the measurement regarding the load.

A connecting and anchoring device. A cable element terminates at opposite ends in respective gate and spine cable termination structures. A gate housing houses a gating portion of the cable element and includes a locking element. The device has a first configuration in which the termination structures are locked together and a second configuration in which the termination structures can be separated from one another by manipulating the locking element. The device in at least the first configuration defines a closed aperture. A spine housing houses a spinal portion of the cable element. The spine housing is attached to the base and the gate housing is pivotally connected to the base so that the gate housing can pivot relative to the spine housing so as to change the configuration of the connecting and anchoring device between the second configuration and a third configuration in which the aperture is open. The cable element includes a cable that extends uninterrupted from the spine housing, through the base, and into the gate housing.
