The disclosed subject matter is in the field of portable platforms that support objects over the space between two support structures, like beams or joists.
During construction and maintenance of homes, buildings, or other structures, a worker or other technician may be required to work over and across the spaces between exposed joists or beams. Such exposed beams or joists pose navigational challenges and safety threats to the worker. So, a need exists for platforms or other supports that may be positioned over the space between two beams/joists so that safety threats and navigational challenges can be reduced or eliminated.
Unitary platforms, like the JoistMate® (represented by U.S. Des. Pat. No. D731,080 (issued Jun. 2, 2015) for “Movable platform”) are simple constructs that somewhat meet the above identified need. In use, the unit is positioned to span two adjacent beams and is capable of supporting a worker or tool over the beams. While capable of providing a platform over adjacent beams or joists, unitary platforms have a few drawbacks. For example, the units can be bulky and hard to both (a) transport and (b) maneuver into position, particularly when space is tight a la an attic. So, a need still exists for compact, easily-transportable and easily-maneuverable platforms or other supports that may be positioned over the space between two beams/joists so that safety threats and navigational challenges can be reduced or eliminated.

In view of the foregoing, an object of this specification is to disclose a rollable platform that may be unfurled in any orientation over exposed floor or ceiling joists. In particular, the platform may be unfurled perpendicular to, oblique to, or parallel to exposed floor or ceiling joists. In a preferred embodiment, the platform is constructed of a specific arrangement of support surface panels and underside joint panels to give the platform both (a) rigidity in a direction that is normal to the support surface via gridlock between the support surface panels and (b) foldability and/or rollability in a direction that is normal to the underside joint panels due to hinged interconnection. Preferably, this duality of rigidity and foldability or rollability enables rolling-up of the platform while at the same time enabling the platform to be unfurled over exposed joists or other spaced supports. In a preferred embodiment, support surface panels and joint panels are held together by a dowel or rod around which the panels pivot in one pivotal direction around the rod but gridlock in the other pivotal direction around the rod.
Other objectives of the disclosure will become apparent to those skilled in the art once the invention has been shown and described. The manner in which these objectives and other desirable characteristics can be obtained is explained in the following description and attached figures in which:
In the figures the following components are represented by the associated reference numeral:
It is to be noted, however, that the appended figures illustrate only typical embodiments of this invention and are therefore not to be considered limiting of its scope, for the invention may admit to other equally effective embodiments that will be appreciated by those reasonably skilled in the relevant arts. Also, figures are not necessarily made to scale but are representative.
Disclosed is a rollable platform that may be unfurled in any orientation over exposed floor or ceiling joists. In particular, the platform may be unfurled perpendicular to, oblique to, or parallel to exposed floor or ceiling joists. In a preferred embodiment, the platform is constructed of a specific arrangement of support surface panels and underside joint panels to give the platform both (a) rigidity in a direction that is normal to the support surface via gridlock between the support surface panels and (b) foldability and/or rollability in a direction that is normal to the underside joint panels due to hinged interconnection. Preferably, this duality of rigidity and foldability or rollability enables rolling-up of the platform while at the same time enabling the platform to be unfurled over exposed joists or other spaced supports. In a preferred embodiment, support surface panels and joint panels are held together by a dowel or rod around which the panels pivot in one pivotal direction around the rod but gridlock in the other pivotal direction around the rod. The more specific aspects of the disclosed platform are described in connection with the figures.
The pattern of knuckles 1220 and barrels 1210 of the joint panel is noteworthy. In a preferred embodiment, the panels 1200 are configured on one side with sets of three barrels 1210 wherein each barrel 1210 in a set of three barrels 1210 is separated by a barrel gap 1212 and each set of three barrels 1210 is separated by a joint barrel space 1215. In the depicted embodiment, the panels are configured on one side with sets of five knuckles 1220, wherein each knuckle 1220 in each set of five knuckles 1220 are separated by a knuckle gap 1222 and each set of five knuckles 1220 are separated by a knuckle space 1225. Other patterns may be used without departing from the spirit and intent of this specification.
Starting on the left in column A, a support surface panel 1100 may be positioned so that the barrels 1110 are projected. Next, an underside joint panel 1200 may be positioned over the support surface panel 1000 so that the barrels 1000 are provided into corresponding joint knuckle spaces 1225 in a way that aligns the joint knuckle shafts 1221 with the barrel shafts 1111. Third, a hinge pin 1300 may be provided through the shafts 1221, 1111 to create an assembly of a support surface panel 1100, an underside joint panel 1200, and a hinge pin 1300 shown in column B.
Moving to column C, another set of components (including surface panel 1100, underside joint panel 1200, and hinge pin 1300) is setup next to the assembly shown in column B. Specifically, the joint surface panel 1200 from the assembly of column B is first positioned so that its joint barrels 1210 are projected. Next, the new joint panel 1200 is set alongside the joint surface panel of the assembly of column B so that the joint barrels 1210 of the assembly of column B are interlocked with the joint knuckles 1220 of the new joint panel 1200 (e.g., so that each joint barrels 1210 of the assembly of column B are provided to the joint knuckle gaps 1222 of the new joint panel 1200 and the joint knuckles of the new joint panel 1200 are provided to the joint barrel gaps 1212 of the assembly of column B). Third, the new support surface panel 1100 is positioned so that its barrels 1110 are positioned both (a) in the joint knuckle space 1225 of the new joint panel 1200 and (b) in the join barrel space 1215 of the assembly of column B. Finally, the new hinge pin 1300 may be provided through the shafts 1221, 1111 of the new joint panel 1200 and surface panel 1100 and the shaft 1211 of the assembly of column B to create an assembly of a support surface panels 1100, an underside joint panels 1200, and a hinge pins 1300 shown in column D.
Moving to column E, yet another set of components (including surface panel 1100, underside joint panel 1200, and hinge pin 1300) may be setup next to the assembly shown in column D. Specifically, the joint surface panel 1200 from the assembly of column D is first positioned so that its joint barrels 1210 are projected. Next, the new joint panel 1200 is set alongside the joint surface panel of the assembly of column B so that the joint barrels 1210 of the assembly of column D are interlocked with the joint knuckles 1220 of the new joint panel 1200 (e.g., so that each joint barrels 1210 of the assembly of column D are provided to the joint knuckle gaps 1222 of the new joint panel 1200 and the joint knuckles of the new joint panel 1200 are provided to the joint barrel gaps 1212 of the assembly of column D). Third, the new support surface panel 1100 is positioned so that its barrels 1110 are positioned both (a) in the joint knuckle space 1225 of the new joint panel 1200 and (b) in the join barrel space 1215 of the assembly of column D. Finally, the new hinge pin 1300 may be provided through the shafts 1221, 1111 of the new joint panel 1200 and surface panel 1100 and the shaft 1211 of the assembly of column D to create yet an assembly of a support surface panels 1100, an underside joint panels 1200, and a hinge pins 1300 (not shown). The process may repeated “n” number of times until a platform 10000 shown in column n is constructed. It should be noted that, even though the platform 1000 shown in column n is of constructed a definite number of panels 1200, 1100, a platform may be constructed of any number of panels 1200, 1100 without departing from the spirit and intent of this specification.
