The present disclosure relates generally to the field of temporary flooring and, more specifically, to improved methods, apparatuses and systems for deploying, using, removing and storing a temporary and removable floor assembly.
In the construction of large structures, temporary supports are often placed to allow workers and materials to be brought in close proximity with work being done on the structure. In many construction scenarios, the work to be done is located in elevated areas. As a result temporary support structures or scaffolds are often built to assist workers and otherwise create temporary platforms on which to stand or hold building materials, tools, etc. Many large structures being built or requiring repair, etc. also require the placement of temporary exposed beams that span or be suspended over otherwise “open” areas. During construction or repair of the structure workers may traverse the exposed beams to assemble structure parts, install fixtures, etc. To prevent falls and injury, workers may be harnessed to a secure part of the structure, or to the scaffolding. Alternatively the scaffolding could be built up around the large structure so the worker would not need to walk across the exposed beams over the open areas. However, scaffolding may be cost or size prohibitive.
To prevent workers from walking on exposed beams in a dangerous fashion, temporary floor panels may be positioned across the exposed beams. However, such floor panels may be unwieldy and/or difficult to deploy and position, and then remove when the construction is complete. For example, each floor panel may weigh in excess of 45 pounds (e.g. a plywood sheet), which must then be raised to the beams and positioned on the beams and then removed and lowered from the beams.
Automated machinery has been proposed to position the flooring and reduce the risk of injury to workers. However, the acquisition and use of such machinery is costly, and the machinery otherwise takes up significant space. Further, it may not be possible to orient such machinery depending on the structure being fabricated. Improved methods and apparatuses for deploying and removing temporary flooring would be advantageous.
According to one aspect, the present disclosure is directed to a method for installing a removable floor assembly comprising positioning a deployable floor assembly at a first location, said floor assembly positioned in a compacted state. The floor assembly comprises a plurality of floor segments, with the floor segments positioned substantially adjacent to one another, and a tensioning cable in communication with the floor segments, with a tensioning device in communication with the tensioning cable to apply a force to the tensioning cable. The compacted floor assembly is deployed from the compacted state at the first location to a deployed state. The tensioning device is actuated to apply a tensioning force to the tensioning cable.
According to another aspect, floor segments are dimensioned to removably interconnect with adjacent floor segments.
In another aspect, floor segments are dimensioned to temporarily mate with adjacent floor segments.
In yet another aspect, the compacted state comprises rolled floor segments, folded floor segments or combinations thereof.
In a still further aspect, the floor segments comprise integral channels to receive the tensioning cable.
In another aspect, at least a portion of the tensioning force is transferred from the tensioning cable to the floor segments.
In yet another aspect, the actuating device applies a tensioning force to the tensioning cable, with the force ranging from about 10 to about 100 lbs.
In another aspect, the tensioning cable is made from a material comprising nylon, steel, stainless steel, aluminum or combinations thereof, etc.
In still another aspect, the floor assembly is deployed onto a support.
In yet another aspect, the floor assembly comprises stops to orient the floor assembly relative to the support.
In a still further aspect, the method further comprises actuating the actuating device to release tension on the tensioning cable, and retracting the floor assembly substantially to the compacted state.
According to a further aspect, the present disclosure is directed to a removable floor assembly comprising a plurality of adjacent floor segments, a tensioning cable in communication with the floor segments, and an actuating device in communication with the tensioning cable.
In another aspect, the actuating device is actuated to apply a tensioning force to the tensioning cable.
In a further aspect, the floor assembly comprises a release mechanism in communication with the actuating device.

The floor assembly comprises a plurality of floor segments, said floor segments positioned substantially adjacent to one another, a tensioning cable in communication with the floor segments, with a tensioning device in communication with the tensioning cable to apply a force to the tensioning cable. The compacted floor assembly is deployed from the compacted state at the first location to a deployed state, and actuating the tensioning device to apply a tensioning force to the tensioning cable.
In yet another aspect, the structure is a stationary structure.
In a still further aspect, the structure is a vehicle.
In a further aspect, the vehicle may be a manned and unmanned vehicles including, without limitation, aircraft, spacecraft, rotorcraft, rockets, satellites, drones, terrestrial vehicles and surface and sub-surface waterborne vehicles, or combinations thereof
Having thus described variations of the disclosure in general terms, reference will now be made to the accompanying drawings, which are not necessarily drawn to scale, and wherein:
According to aspects, the present disclosure is directed to methods, apparatuses and systems for installing a removable floor assembly.
As shown in the FIGs. and otherwise described herein, a temporary, removable floor assembly comprises a plurality of floor segments, with the floor segments positioned substantially adjacent to one another. A tensioning cable is in communication with the floor segments, and a tensioning device is in communication with the tensioning cable to apply a tensioning force to the tensioning cable. The floor assembly is deployed from a compacted state to a deployed state, and the tensioning device is actuated via an actuating device to apply a tensioning force to the tensioning cable and, maintain the deployed floor assembly in the deployed state. When, and if desired, the tensioning device is actuated to release tension on the tensioning cable via a release mechanism, and the removable floor assembly is returned from its deployed state to its compacted state.
According to another aspect,
According to another aspect of the present disclosure, as the tensioning force is applied to the compacted floor assembly 40, the assembly 40 will unwind or unroll to a desired position in contact with a support structure. In other words, according to this aspect, the application of tensioning force to the compacted floor assembly serves to both unwind the compacted floor assembly to a desired position along the support structure, and then also tighten the floor assembly into the final, substantially linear and semi-rigid or rigid deployed state.
According to further aspects, the disclosed floor assembly includes a plurality of segments that removably interlock or removably mate together and are reversibly secured together by a tensioning device, such as, for example, a tensioning cable that is in communication with each floor segment. This allows a floor assembly to be compacted for storage (e.g. rolled up, stacked, or otherwise compacted into a desirable orientation) and that is predictably designed to obtain a smaller footprint in the compacted state than known floor assemblies. The floor assembly in the compacted state can more safely and efficiently be delivered to a location for deployment, such as elevated beams or other desired support structure that may be “open” and otherwise be unsafe for workers to traverse.
According to aspects of the present disclosure, once the compacted floor assembly is placed at a deployment location, a single worker can activate the actuation device that applies a desired tensioning force to the floor segments via the tensioning cable that is in communication with the individual floor segments. It is further contemplated that the process could be entirely automated, and even remotely automated, as a signal can be sent to and received by the actuating device to actuate the tensioning device. In a further aspect, the tensioning device may respond to manual force, whereby a worker operates a manual crank to deliver the required tensioning force. According to a contemplated aspect, a mechanical means such as, for example, an electrical device such as an electric drill may engage to a mechanism such as, for example, a crank configured to engage an actuating device to wind or unwind the cable (for example, about a take-up spindle, etc.) to deliver or release tensioning force to the tensioning cable, as desired. The rigidity or semi-rigidity of the deployed floor assembly is therefore the result of the mating features predictably located on the individual floor segments that are dimensioned to removably mate, or removably interconnect, coupled with the tensioning force delivered to the floor assembly via the tensioning cable. According to aspects, the interlocking or mating features comprise male and female mating features such as, for example, tabs and slots, although any suitable features that predictably assure temporary and removable interlocking are contemplated. For the purposes of this disclosure, the terms “interlock and “mate” are used interchangeably and are equivalent terms.
More than one floor assembly can be deployed across a support structure such as, for example, a beams, or series of spaced beams, etc., to form temporary safe flooring over the support structure. According to a further aspect, the deployed floor assemblies can be secured in a desired position and orientation relative to the support structure by positioning stops integral with, or added to the underside of one or more of the floor segments. A similar predictable positioning of the deployed floor assembly can be achieved, and is therefore contemplated herein, by providing floor segments comprising lateral or otherwise positioned protrusions that are dimensioned to predictably engage a support structure. Such positioning features on one or more of the floor segments contact the beam in a predictable fashion to prevent the deployed floor assembly from moving undesirably relative to the support structure.
When the need for the deployed floor assembly has ceased (e.g. the need to safely support workers on a suspended structure at a specific location is no longer required), according to presently disclosed aspects, the deployed floor assembly can be removed from the support structure and stored more easily and quickly than known temporary flooring systems. According to aspects of the present disclosure, to return the deployed floor assembly to a compacted state, the system is substantially reversed, whereby a release mechanism in communication with an actuating device is activated to release tension on the tensioning cable. In this way, the deployed floor assembly can be returned to the compacted state (i.e. the compacted floor assembly) for storage or further use elsewhere.
Accordingly, aspects of the present disclosure contemplate an efficient and cost-effective, reusable floor assembly that is in strong contrast to known flooring systems. Unlike known systems where floor segments are either damaged upon removal or designed to be disposable, according to aspects of the present disclosure, the presently disclosed floor systems are designed for reuse, are significantly easier to return to a compacted state, and are also significantly easier to store between uses. As mentioned above, the floor systems according to the present disclosure further take up a significantly smaller footprint in their compacted state.
The floor segments may, according to aspects of the present disclosure, be made from any suitable material that is strong enough to support a desired weight load. Contemplated materials include, without limitation, wood, metal, plastic, composite material, rubber, concrete, cementaceous material, and combinations thereof, etc.
Further, the tensioning cable, according to aspects of the present disclosure, may be made from any suitable material that is strong enough to deliver a desired tension to the floor segments and maintain the desired positioning of the floor segments in an interconnected, or mated state. Contemplated materials include, without limitation, nylon, steel, stainless steel, aluminum or combinations thereof, etc.
Still further, the actuating device for delivering tension to the tensioning cable, according to aspects of the present disclosure, may be any mechanical device cable of securely engaging an end of the tensioning cable, providing a take-up function (e.g. winding function, etc.), and retaining tension on the tensioning cable for a desired period of time while the floor assembly is in a deployed and tensioned state. Suitable actuating devices include, without limitation, a ratcheting winch, rank ratchet and clamp, locking crank wheel, cable reel, and combinations thereof. As stated above, the contemplated actuating devices may be manually actuated, may be automated to be, for example, electrically driven, and may be able to receive a signal sent from a remote or integrated device to actuate and deliver, maintain and release a desired amount of tension relative to the tensioning cable and the floor assembly. A contemplated amount of force provided to the floor assembly and tensioning cable will vary with the demands and design of each particular floor assembly based on a desired use. Contemplated force/tensions range from about 10 to about 100 lbs.
According to present aspects, the floor segments removably or temporarily connect, mate or otherwise engage in a way such that when adequate tensioning force is delivered to the tensioning cable that is in communication with the adjacent floor segments, the tensioning force that is transferred to the floor segments maintains adjacent floor segments, and the floor assembly overall in a semi-rigid or rigid orientation. The features that are integral with the floor segments, and that are contemplated to facilitate the mating of adjacent floor segments can be any reciprocal male/female-type physical structures that insure an intimate “fit” that allows for secure engagement. However, the contemplated mating features must also be mutually and cooperatively dimensioned to easily disengage when the tensioning force diminishes as the actuating device releases tensioning force so that the floor assembly can be returned to a compacted state. While aspects are directed to physical mating features on the floor segments, the present disclosure further contemplates other integral engagement means such as, for example, and without limitation, magnets activated through applying electromagnetic fields that can selectively engage and disengage adjacent floor segments into a deployable and compactable floor assembly, etc.
While aspects of the present disclosure contemplate the tensioning cable engaging the floor segments through and via internal and integral channels in the individual floor segments, other variations (e.g. an exposed channel along an outer surface of the floor segments, or the tensioning cable positioned adjacent to an outer surface of the floor segments) are also contemplated so long as the tensioning cable is able to apply an adequate tensioning force to the floor segments to achieve a rigid or semi-rigid floor assembly capable of supporting a desired weight load.
While illustrative aspects of the disclosure are directed to removable temporary floor assemblies that can be deployed from a compacted state of certain configurations such as, for example and without limitation, a rolled-up, stacked, or expanding accordion configuration, it will be understood that all geometries and configurations of the floor assembly in the compacted state are contemplated. That is, it may be possible to deployed a floor assembly according to the present disclosure, where the compacted state is geometrically complex with the assembly unfolding to a deployed state, such as, for example, deploying irregularly, or in stages to cover a linear or non-linear support structure. The present disclosure therefore contemplates all such variations so long as the floor segments are in communication with a tensioning cable that can transfer tensioning force to the floor segments to achieve a rigid or semi-rigid temporary, and preferably reusable, floor assembly that can revert to a compacted state after its deployment (once the tensioning force is released).
Further, aspects of the present disclosure concern temporary and reusable floor assemblies for any structures including, without limitation, stationary structures, large vehicles, including, without limitation, manned and unmanned vehicles including, without limitation, aircraft, spacecraft, rotorcraft, rockets, satellites, terrestrial vehicles surface and sub-surface waterborne vehicles, and combinations thereof, etc.

The terms “comprising,” “including” and “having” are intended to be inclusive and mean that there may be additional elements other than the listed elements. Although this disclosure has been described with respect to specific embodiments, the details of these embodiments are not to be construed as limitations. While the preferred variations and alternatives of the present disclosure have been illustrated and described, it will be appreciated that various changes and substitutions can be made therein without departing from the spirit and scope of the disclosure.
