The present invention pertains generally to Relocatable Habitat Units (RHUs) for use in simulating an environment for a military combat training scenario. More particularly, the present invention pertains to an RHU that can be assembled and disassembled on-site, using panels that can be maneuvered, positioned and interconnected by no more than two men. The present invention is particularly, but not exclusively, useful as a system and method for the complete assembly of an RHU using only a same, single, hand-operated tool.
Military training must necessarily be conducted in an environment that will simulate anticipated combat operations as accurately as possible. For a comprehensive training program, this requires the ability and flexibility to relocate and set-up several different types of training environments. In general, training sites may need to selectively simulate either an urban, suburban or an open terrain environment.
For a training site, the realism that can be attained when simulating a particular environment can be clearly enhanced by introducing indigenous persons (i.e. actors) into the training scenario. Further, in addition to the indigenous persons, urban and suburban environments can be made even more realistic when trainees are confronted by obstacles, such as buildings (e.g. habitats). In most instances, such structures can be relatively modest. Nevertheless, their integration into the training scenario requires planning.
Providing realistic buildings for a training environment requires the collective consideration of several factors. For one, the buildings need to present a visual perception that is accurate for the particular training scenario. Stated differently, they need to “look the part”. For another, it is desirable that structures assembled on the training site be capable of disassembly for relocation to another training site and subsequent use. With this last point in mind, an ability to easily assemble and disassemble a building (i.e. training aide) is a key consideration.
Heretofore, military combat training scenarios have been conducted either on open terrain, or at locations where there have been pre-existing buildings. The alternative has been to bring prefabricated components of buildings to a training site, and then assemble the components to create the building. Typically, this has required special equipment and considerable man-hours of labor.
In light of the above, it is an object of the present invention to provide a construction set and method for assembling and disassembling an RHU, at a training site, with as few as two persons. Still another object of the present invention is to provide a construction set that requires the use of only a same, single, hand operated tool for the assembly and disassembly of an entire RHU. Yet another object of the present invention is to provide a construction set for the assembly and disassembly of an entire RHU that is relatively simple to manufacture, is extremely simple to use, and is comparatively cost effective.
A Relocatable Habitat Unit (RHU) in accordance with the present invention is assembled using a plurality of substantially flat panels. For this assembly operation, each panel includes male (M) and female (F) connectors. Specifically, these connectors are located along the periphery of the panel. Importantly, all of the male connectors can be engaged with a respective female connector using the same tool. Thus, an entire RHU can be assembled and disassembled in this manner. Further, each panel is sufficiently lightweight to be moved and positioned by one person. As a practical matter, a second person may be required to use the tool and activate the connectors as a panel is being held in place by the other person.
In detail, a construction set for use with the present invention includes a plurality of panels and only the one tool. Each panel has a periphery that is defined by a left side edge, a right side edge, a top edge and a bottom edge. Selected panels, however, can have different configurations that include a door or a window. Still others may simply be a solid panel. In particular, solid panels are used for the floor and ceiling (roof) of the RHU. Essentially, there are wall panels, floor panels, and ceiling panels. Each panel, however, regardless of its configuration, will include at least one male connector and at least one female connector that are located on its periphery.
In addition to the wall, floor, and ceiling panels, the construction set also includes corner connections and ceiling attachments. Specifically, corner connections are used to engage wall panels to each other at the corners of the RHU. The ceiling attachments, on the other hand, allow engagement of roof panels with the top edges of wall panels.
The placement and location of male (M) and female (F) lock connectors on various panels of the construction set is important. Specifically, along the right side edge of each wall panel, between its top edge and bottom edge, the lock configuration is (FMMF). Along its left side edge, the lock configuration is (MFFM). Further, along the top edge the lock configuration is (MM), and along the bottom edge it is (M or F [depending on the connector of the floor panel]).
Unlike the panels, the corner connections are elongated members with two surfaces that are oriented at a right angle to each other. The lock configurations for a corner connection are (F--F) along one surface and (-FF-) along the other surface. Like the corner connections, the ceiling attachments also present two surfaces that are at a right angle to each other. Their purpose, however, is different and accordingly they have a (FF) lock configuration on one surface for engagement with the top edge of a wall panel. They also have either a (MM) or a (FF) configuration along the other surface for connection with a ceiling panel.
Importantly, in addition to the above mentioned panels, connections and attachments, the construction set of the present invention includes a single hand tool. Specifically, this hand tool is used for activating the various male (M) connectors for engagement with a female (F) connector. For the present invention, this tool preferably includes a hex head socket, a drive that holds the hex head socket, and a ratchet handle that is swivel attached to the drive.
For assembly of the RHU, the first task is to establish a substantially flat floor. This is done by engaging male (M) connectors on a plurality of floor panels with female (F) connectors on other floor panels. The floor is then leveled using extensions that can be attached to the floor. Next, a wall is erected around the floor of the RHU by engaging a male connector on the right side edge of a respective wall panel with a female connector on the left side edge of an adjacent wall panel. Recall, the lock configurations on the left and right edges of wall panels are, respectively, (FMMF) and (MFFM). Additionally, the bottom edge of each panel in the wall is engaged to the floor using mutually compatible male (M) and female (F) connectors. Finally, the roof is created for the RHU by engaging male (M) connectors on ceiling panels with female (F) connectors on other ceiling panels. The ceiling attachments are then engaged to the assembled roof. In turn, the ceiling attachments are engaged to the top edge of a wall panel using mutually compatible male (M) and female (F) connectors. All connections for the assembly of the RHU are thus accomplished using the same tool.
The novel features of this invention, as well as the invention itself, both as to its structure and its operation, will be best understood from the accompanying drawings, taken in conjunction with the accompanying description, in which similar reference characters refer to similar parts, and in which:
Referring initially to
For the present invention there are essentially three different types of panels 12. These are generally denominated by their structural function in the RHU 10 and are: a wall panel 12, a ceiling panel 14 and a floor panel 16. Further, the wall panels 12 may have any of three different configurations. Specifically, these configurations are shown in
It is an important aspect of the present invention that the panels 12, the corner connections 26 and the ceiling attachments 28 have compatible male (M) and female (F) locking connectors. For example,
In
Like the corner connections 26, the ceiling attachments 28 are elongated members. Also, the ceiling attachments 28 have a first surface 46 and a second surface 48. Like the corner connections 26, the first surface 46 of the ceiling attachment 28 needs to be oriented at a right angle (i.e. orthogonal) to its second surface 48. The similarities end there, however. As shown in
The interaction of M and F locking connectors will be best appreciated with reference to
Still referring to
For an engagement between an M and an F locking connector, the connectors need to first be juxtaposed with each other. This can be accomplished in any of several ways. For instance, either side edges 32/34 of panels 12 are juxtaposed to each other (e.g. see
Once an M and an F locking connector have been properly positioned with each other, as indicated above, the hex head 52 of tool 50 is inserted into the hex socket 60. The tool 50 is then turned in the direction of arrow 74. This causes the ramps 64/66 of cam lock 62 to respectively go behind the abutments 70/72. The M and F locking connectors are then engaged.
In accordance with the present invention, assembly of the RHU 10 is best accomplished by following a predetermined sequence of steps. First, a plurality of floor panels 16 is engaged together to form a floor for the RHU 10. The floor is then positioned and leveled by adjusting the extensions 24 that are provided for that purpose. Next, starting at a corner for the RHU 10, a corner connection 26 is engaged with panels 12. Note: at this point the respective ledges 40 on panels 12 are positioned to rest on the adjacent floor panel 16. Also, the bottom edges 38 of the wall panels 12 are engaged through M/F locking connections to the adjacent floor panel 16. This continues until all walls of the RHU 10 have been erected. As intended for the present invention, door panels 18, solid panels 20 and window panels 22 can be used as desired in the assembly of the walls for the RHU 10.
After the walls of RHU 10 have been erected, the roof is created. Specifically, ceiling attachments 28 are engaged, as required, with a single ceiling panel 14 (see
Importantly, all of the tasks described above for the assembly of an RHU 10 are accomplished using only the tool 50. Axiomatically, it follows that the entire RHU 10 is held together with only a plurality of M/F locking connections.
While the particular Relocatable Habitat Unit as herein shown and disclosed in detail is fully capable of obtaining the objects and providing the advantages herein before stated, it is to be understood that it is merely illustrative of the presently preferred embodiments of the invention and that no limitations are intended to the details of construction or design herein shown other than as described in the appended claims.
