Problems solved by technology

[0003] However, for permanent fall protection, e.g. on construction equipment with overhead installations, it may not be appropriate to maintain a safety net suspended across the entire overhead area due to the structure of the equipment, the working height, the obstructions it causes and its expense

Embodiment Construction

[0035] refer to figure 1 and 2 , a first embodiment of a safety net assembly comprising a bag 1 having a narrow closed end 2 and an opposite wide open opening 3 provided for receiving a fixed device, such as a lighting device. 50( Figure 7 As shown), the opening 4 of the lighting device is mounted on a component, such as a beam 51, above (overhead). A cable 33 passes through the mesh 12 on the opening 3 in a loop, and cooperates with a choker 52 to pull the mesh 12 together to close the opening 4 . One end of the cord 33 is looped over the beam 51 to secure the device in place.

[0036] In the first embodiment shown, the mesh may consist of a length of wire 5 which may be continuous (i.e. a single piece) or discontinuous (e.g. comprising end-to-end joints) and A degree of flexibility and elasticity is provided to the bag 1, allowing it to be expanded in a direction transverse to the wire arrangement to accommodate devices of different sizes, while being easily collapsed. ...

Abstract

A fall arrest safety net assembly has the form of a bag constructed of wire mesh, with a closed end and an opposing open mouth about which a plurality of eyes are spaced. An elongate line has opposing first and second ends, first and second line portions of the line being disposed adjacent the first and second ends respectively, an intermediate portion of the line located between the first and second line portions. A choker fitting has two faces between which a plurality of openings extend, and an end-securing fixture on the choker fitting. The first portion of the line is connected in a ring by the choker fitting, the first end being fixed to the end-securing fixture, the first portion extending through the eyes for drawing the mouth closed, and the intermediate portion extending through the openings in the choker fitting.

Description

technical field [0001] The invention relates to a safety net with attachment means for fastening to a building element, in particular for use as a fall arrest device. Background technique [0002] When working at heights, safety devices should be provided to stop falling debris in order to protect persons below the work position. Typically, the mounting net can be hung just below the working height and fastened to a fixture such as a freestanding post or a wall-mounted end-fix. [0003] However, for permanent fall protection, e.g. on construction equipment with overhead installations, it may not be appropriate to maintain a safety net suspended across the entire overhead area due to the structure of the equipment, the working height, the obstructions it causes and its expense . Accordingly, there is a need for an improved safety device that overcomes these disadvantages and that is relatively cheap to manufacture and easy to install. It is an object of the present inventi...
