Definitions

  • the present invention relates to a safety unit.
  • the invention relates to a safety unit for use in or on structures such as scaffold or scaffolding.
  • Scaffold installations typically have guardrails around platform levels in order to prevent users working on the scaffold from falling. Edge protection may also be provided at the top of elevated surfaces. However, whilst these semipermanent protection means, once installed, are useful in preventing falls by workers using the scaffold, alternative protection devices are often required for workers involved in constructing, assembling, repairing or altering the scaffold.
  • Advanced guardrails provide a fixed Guardrail that is installable from a secure position on a lower level, such that when the scaffolder proceeds to the higher level, there are Guardrails already in place to prevent falling.
  • the PlusGard® system consists of uprights with a Guardrail extending between them.
  • the uprights are provided with coupling devices for releasably coupling the uprights to the scaffold.
  • the Guardrail is connected to the uprights via articulated connections. By uncoupling, moving and recoupling the uprights, the vertical position of each upright can be adjusted so as to raise or lower the Guardrail, for example, to position the Guardrail to protect a higher level that has not been constructed and provided with permanent Guardrails.
  • the PlusGard® comes in component form and can be assembled and disassembled for transport and storage and appropriately sized components can be selected for each job.
  • guardrail products are not difficult to understand or use, they do require pre-planning for use and selection of appropriate quantities and parts.
  • the amount and size of the parts needed varies from job to job depending on the configuration and bay lengths of the scaffolds involved.
  • advanced scaffolding can add extra materials due to the components of the advanced guardrail itself and also additional scaffolding components required when using the advanced guardrail. This adds time and weight to each job and also results in the need to bring temporary assembly/dismantle aid items to and from each job.
  • a safety unit for use with a scaffolding structure or other structure, the unit comprising a support means supporting a worker's platform at an elevated position above the ground or a working deck of the structure, a fall prevention barrier surrounding at least part of the worker's platform, access means for climbing from the ground or working deck to the worker's platform, and securing means for securing the unit to the structure for stability.
  • the support means comprises one or more pairs of legs which support the platform from the ground or working deck.
  • the legs and/or fall prevention barrier are foldable into planes generally parallel to the platform when the unit is in a non-operative collapsed condition.
  • the legs and/or the fall prevention barrier are constructed from lengths of hollow tubular material which is joined by articulated joints to allow the unit to be folded into its non-operative collapsed condition.
  • the weight of the unit is preferably less than 24kg.
  • Locking means are provided to lock the folding legs and/or fall prevention barrier in an erected operative condition.
  • the access means may comprise rungs carried by the legs.
  • the fall prevention barrier includes at least one access gate.
  • the securing means may be designed to engage a horizontal rail of a scaffolding structure.
  • the securing means may comprise a pair of hooks which grip the horizontal rail.
  • the hooks may include friction means (such as rubber blocks) for contact with the horizontal rail.
  • the legs extend upwardly above the platform to form part of the fall prevention barrier and access rungs extend between the legs.
  • the fall prevention barrier may also include a rear frame on which the platform is pivotally mounted and which includes vertical posts joined by one or more generally horizontal bars.
  • the fall prevention barrier also includes one or more further horizontal bars which connect the leg extensions and rear frame vertical posts.
  • Openable access means extend between the upward leg extensions to allow access to the platform for an operator using the access rungs.
  • This openable access means preferably comprises a gate pivoted on one of the upward leg extensions.
  • the securing means is in the form of a pair of hooks to hook over a generally horizontal rail of a scaffolding and the rear frame vertical posts extend downwardly below the platform to form horns which hook behind a lower generally horizontal rail of the scaffolding to prevent toppling of the unit when in use.
  • a further hook may also be provided which is spring mounted on the unit and which hooks under the lower horizontal rail to ensure that the hooks and horns remain in contact with their respective rails.
  • the further horizontal bars which connect the leg extensions and the rear frame posts are pivoted in their central regions so that the unit can fold with the rear frame and upward leg extension lying generally parallel to each other.
  • the platform is also pivotally connected with a bar which extends between the legs by a pair of arms, one end of each arm being pivoted to the platform and the other end to the bar which extends between the legs so that, as the unit is folded, the platform is pivoted into a plane generally parallel to the planes of the upward leg extensions and rear frame, the platform resting on said bar when the unit is opened up and in its operating condition.
  • the support means and securing means may be provided by separate sets of hooks which engage different generally horizontal rails of the scaffolding.
  • the platform may be dimensioned to provide a work space for a single operator.
  • the platform is dimensioned to provide a working space for two or more operators in a side by side configuration.
  • the safety unit may be used on or with other structures, such as open frame metal mesh structures or structures formed from elongate metallic members, that are found in other environments, for example, masts, towers, pylons, derricks, rigs or cranes.
  • the elevation of the platform provides access to a not yet fully constructed upper level of a scaffold which may not yet have permanent or semi- permanent protection, such as an outer scaffold guardrail in place.
  • the safety unit provides both access and anti-fall protection whilst working on the upper level and particularly whilst installing or removing the new permanent guardrail on the upper level.
  • the device By making the safety unit portable, the device may be moved from one area of work to another easily.
  • the unit is sized so as not to fit the scaffold like advanced guardrails. This means that a single unit can be used for a wide range of different sized and shaped scaffolds.
  • the fall prevention barrier preferably extends around all four sides of the platform and is provided with an access section, such as a gate, which is biased into a closed position. In this way, complete protection from falls on all sides can be achieved, yet still allow for access onto the platform.
  • the biasing of the access section mitigates the effects of the user forgetting or incorrectly closing the access section, and prevents the access section opening during use.
  • the access section may be selectively lockable in an at least partially open configuration such that it forms a guardrail for users using the ladder.
  • the safety unit may fold substantially flat and/or into a more compact configuration than the operating configuration. In this way, the safety unit may be moved and stored easily. This makes the unit both stackable and easy to carry. Furthermore, this feature allows for rapid assembly/disassembly of the device as the safety unit needs only to be unfolded and locked in position to be ready for use.
  • the device can be used with a range of scaffold sizes and types without the need for special selection or assembly of components.
  • a structure such as a scaffold, having at least one safety unit according to the present invention secured thereto.
  • a method of working on a scaffolding structure comprising securing a safety unit according to the first aspect of the invention to the structure to allow assembly or disassembly of an elevated stage of the structure whilst providing fall prevention protection for workers standing on the platform of the safety unit.
