Description

FIELD OF INVENTION

The present invention relates generally to a frame for a transportable shelter. The frame members are designed in an interlocking, piecemeal construction, such that various embodiments of a frame may be produced based on the intended use of the transportable shelter.

BACKGROUND

Transportable shelters (e.g., a tent) are used in various situations. For example, a person may use a tent to go camping. In another example, military personnel often use transportable shelters for training or when stationed in a foreign country.

Standard transportable shelters include an inter-locking frame system that creates a hoop, Quonset hut, angular, or otherwise frame-based structure, and the frame-based structure is covered with a fabric to create side and end walls of the structure. Current transportable shelters are designed to withstand particular environmental conditions (e.g., wind, snow loading, cold temperatures, etc.) and are offered as a catch-all for these environmental conditions. Therefore, transportable shelters used in desert and tropical regions are designed for protection against cold and snow, even though it is unlikely that transportable shelters used in these regions will be subjected to cold and snow.

The frame of current transportable shelters is typically made from a metal material, such as aluminum, and requires hard tooling to bend beams and cut gussets. In addition, the frame often requires welding various pieces of the frame together. Frames made from aluminum tend to be difficult to weld because of the age hardening process.

SUMMARY

An exemplary frame for a transportable shelter includes a first base member, a second base member, a plurality of structural members, and a plurality of purlins. Each of the structural members has a first end that is connectable to the first base member, a second end that is connectable to the second base member, and at least two interconnecting members that extend between the first end and the second end. A first interconnecting member of a structural member is connectable to a second interconnecting member of the structural member. The plurality of purlins are configured to connect one structural member to another structural member.

An exemplary methodology for manufacturing a frame for a transportable shelter includes determining a customized design for the frame of the transportable shelter. The methodology further includes creating base members for the frame of the transportable shelter. The base members are created to have a desired size and shape based on the determined customized design. The methodology also includes creating two or more structural members for the frame of the transportable shelter. The structural members are created to have a desired size and shape based on the determined customized design for the frame. The methodology further includes creating a plurality of purlins for the frame of the transportable shelter. The purlins are created to have a desired size and shape based on the determined customized design for the frame.

An exemplary methodology for installing a frame for a transportable shelter includes determining a desired location for the transportable shelter. The methodology further includes placing an installation sheet at the desired location for the transportable shelter. The installation sheet includes marked location for placing the base members, the structural members, and the purlins for the frame of the transportable shelter. The methodology also includes attaching the base members to a ground surface at the marked location for placing the base members, connecting each structural member to the base members, and connecting each structural member to at least one adjacent structural member by one or more of the plurality of purlins.

DETAILED DESCRIPTION

With the vast number of possible locations having varying environmental conditions where both civilian and military personnel require shelter, there exists a need for rapidly deploying, compact, easy to transport shelters designed to tolerate disparate temperatures and weather conditions. A transportable shelter is desired that is easily customizable, allowing for installation in areas where disparate designs create more stable, better-suited habitation for prolonged installation. Shelters produced in this fashion are designed for use adjacent to buildings, to extend the covered area when combined with an ISO container, or to withstand wind, snow, temperature, or seismic conditions upon request.

Transportable shelters used by the military must meet certain requirements. For example, the shelter must be designed to be transportable by a cargo plane. Accordingly, a transportable shelter that is capable of being stored and transported in a reduced amount of space is desired. In addition, transportable shelters used by the military need to be able to withstand weather conditions of areas in which the transportable shelters are being used. Therefore, a transportable shelter that can be customized to withstand any of a various number of weather conditions is desired.

The present application is directed to a frame for a structure in which the frame has a system of interlocking panels, and in which the panels may be interlocked in various ways based on the needs of the proposed structure. That is, the various ways of interlocking the panels makes the structure customizable. Customizations include, for example, the shape of the structure (e.g., hoop-shaped, Quonset hut-shaped, etc.), situation specific designs for support beams of the structure (e.g., strengthening of a corner and/or shoulder haunch, thickness of the beams specified for advanced stability in wind, etc.), and beam connection methods to facilitate ease of installation and construction security of the structure.

In addition, the present application is directed to a structure that can be easily stored and transported. For example, in certain embodiments, the frame includes several members that are mechanically connected together to create the frame. The mechanical connections can be made using hinge assemblies that allow the members to fold over each other to reduce the space required for storing and transporting the frame.

The frame described in the present application has several advantages over current frames. For example, frames that utilize several members that are mechanically connected together allows for frames to be manufactured to the specific requirements of the user. That is, the several members of the frame can be manufactured separately from each other, and, subsequently, the members of the frame can be mechanically connected. For example, Computer Numerical Control (“CNC”) cutting (e.g., plasma cutting, laser cutting, water jet cutting, etc.) can be used to pre-cut the various members of the frame to a desired size and/or shape, and these pre-cut members can be mechanically connected to each other. This manufacturing process makes it easy to manufacture a frame to the specifications desired by a user. Comparatively, current frames are manufactured using hard tooling to bend beams, and members of the frames are welded together to create the frame. This manufacturing process is time consuming and does not lend itself useful for manufacturing customizable frames because the entire manufacturing process must be altered to change the design of the frame. In addition, the use of mechanical connections (as described in the frames disclosed in the present application) is advantageous, as compared to the current use of welded connections, because welded connections can structurally weaken the frame.

The general inventive concepts of the present application will now be described by referencing the following exemplary embodiments. The description with reference to the following exemplary embodiments is not intended to limit the scope of the claims in any way, and the terms used in the claims have their full ordinary meaning.

Referring to FIG. 1, an exemplary embodiment of a frame 100 for a transportable shelter includes a first base member 102, a second base member 104, a plurality of structural members 106a-g, and a plurality of purlins 108. A first end 205 (FIG. 2) of each structural member 106a-g is connected to the first base member 102, and a second end 207 (FIG. 2) of each structural member 106a-g is connected to the second base member 104. The purlins 108 attach a structural member 106a-g to an adjacent structural member and provide support to maintain the frame 100 in an upright position. The first base member 102 and the second base member 104 may be made of any suitable material, such as, for example, steel, aluminum, etc. The structural members 106a-g may be made of any suitable material, such as, for example, steel, aluminum, etc. The purlins 108 may be made of any suitable material, such as, for example, steel, aluminum, etc. The frame 100 includes a width X and a length Y. In one exemplary embodiment, the width X is about 30 feet and the length Y is about 50 feet. However, the width X and the length Y may be any suitable distances based on the desired specifications of the user. That is, the frame 100 can be constructed to include the proper amount of structural members and purlins that are required to make the size of the frame 100 meet the desired specifications of the user.

The frame 100 includes a plurality of bays 110a-f, in which each bay 110 includes an adjacent pair of the structural members 106a-g that are attached by the first base member 102, the second base member 104, and a plurality of purlins 108. In the embodiment shown in FIG. 1, the frame 100 includes six bays 110a-f. However, the frame 100 may be configured to include any of a various numbers of bays, such as, for example, between two bays and ten bays, such as between three bays and nine bays, such as between four bays and 8 bays, such as between about five bays and seven bays, such as six bays. In certain embodiments, the frame 100 may include more than ten bays. The number of bays 110a-f depends on the size of the frame 100 and the number of structural members 106a-g required to make the frame. Referring he size of the bays 110a-f depends on the length Z of the purlins 108 and the width X of the structural members. The length Z of the purlins 108 may be any suitable length based on the desired characteristics of the frame 100.

Referring to FIG. 2, the bay 110a for the frame 100 of FIG. 1 is shown. While the following description refers to bay 110a, it should be understood that the description also applies to bays 110b-f. In the illustrated embodiment, the bay 110a includes the structural member 106a and the structural member 106b, in which the structural members 106a,b are connected by the first base member 102, the second base member 104, and five purlins 108. In alternative embodiments, the structural member 106a and the structural member 106b may be connected by any suitable number of purlins 108 that maintains the bay 110 in an upright position, such as, for example, three purlins, four purlins, five purlins, six purlins, etc.

Still referring to FIG. 2, each structural member 106a,b includes six interconnecting members 212a-f. The interconnecting member 212a of each structural member connects to the first base member 102 at connection point A and the adjacent interconnecting member 212b at connection point B. The interconnecting member 212c connects to adjacent interconnecting member 212b at connection point C and to another adjacent interconnecting member 212d at connection point D. The interconnecting member 212e connects to adjacent interconnecting member 212d at connection point E and to another adjacent interconnecting member 212f at connection point F. The interconnecting member 212f connects to the second base member 104 at connection point G. In various embodiments, the connection between interconnecting members 212a-f at connection points B-F are adjustable between a pivotal connection and a fixed connection, such as, for example by connections using hinge assembly 1300 (FIG. 13). In certain embodiments, the connection between interconnecting members 212a,f and the first base member 102 or the second base member 104 is adjustable between a pivotal connection and a fixed connection, such as, for example, by a connection using hinge assembly 2200 (FIG. 22). The connection between the interconnecting portions 212a-f and adjacent interconnecting portions 212a-f, the first base member 102, or the second base member 104 is described in more detail below. Pivotal connections between the interconnection portions 212a-f allow for each structural member 106a-g to be folded over each other, which allows for a reduction in space for storing and/or transporting the structural members.

In alternative embodiments, each structural member 106a-g may be constructed of a single member or any various number of interconnecting members 212. For example, each structural member 106a-g may include two interconnecting members, three interconnecting members, four interconnecting members, five interconnecting members, six interconnecting members, seven interconnecting members, etc. The number of interconnecting members 212 may depend on the size of the frame 100. That is, the number of interconnecting members 212a-f may depend on the width X and the height H of the frame 100. A frame 100 that utilizes structural members 106 made from interconnecting members 212 is advantageous because it allows a frame to be customizable to a user's preferences. That is, the width X and the height H of the frame 100 can be easily customized based on the number of interconnecting members 212a-f that are used to create the structural members 106a-g. Comparatively, as described above, current frames for transportable shelters are made using hard tooling to bend beams, which makes it difficult to manufacture customizable frames.

Still referring to FIG. 2, each purlin 108 connects the structural member 106a to structural member 106b. In the illustrated embodiment, a purlin 108 is connecting the structural members 106a,b at each of the connection points B-F. In alternative embodiments, the connections between the purlins 108 and the structural members 106a-g are located at connection points that are different than the connection points B-F between the interconnecting members 212a-f. The connections between the purlins 108 and the structural members 106a-g is described in more detail below.

In an exemplary embodiment, each structural member 106a-g is made of a first portion and a second portion, in which both the first portion and the second portion includes one or more of the interconnecting members 212a-f. In one embodiment, the first portion includes interconnecting portions 212a-c, and the second portion includes interconnecting portions 212d-f. In this embodiment, interconnecting member 212c of the first portion is connected to interconnecting member 212d of the second portion at connection point D. In alternative embodiments, the structural members 106a-g may include more than two portions that each include one or more interconnecting members 212a-f. Structural members that include multiple portions that are connectable to each other to create the structural member are advantageous because separating the structural member into multiple portions allows for a reduction in space when storing and/or transporting frame. That is, the multiple portions can be transported in an unconnected state, and, then, the portions can be connected during installation of the frame.

Referring to FIGS. 1 and 2, the structural members 106a-g are in the form of an arch (i.e., a curved shape). However, in an alternative embodiment, the structural members 106a-g may be in the form of a polygonal shape. Additional embodiments of the shape of the structural members 106a-g are shown in FIGS. 3A and 3B. Referring to FIG. 3B, the inner portion 318 of the structural member 106 has a polygonal shape, and the outer portion 319 of the structural member has a curved shape. Referring to FIG. 3A, the inner portion 320 of the structural member 106 has a curved shape, and the outer portion 321 of the structural member has a polygonal shape. In some embodiments, the structural members 106a-g may have a rectangular shape. The structural members 106a-g may take any form such that the frame 100 is capable of supporting a fabric cover (not shown) of the transportable shelter. The customizable shape of the frame 100 is advantageous because it allows the frame to be made to a user's preferences. The use of CNC cutting to create multiple members having different shapes that are configured to be mechanically connected allow for easy manufacturing of structural members having different shapes. Comparatively, the use of hard tooling to bend beams to create different shapes is difficult and time consuming.

Referring to FIG. 4, in an exemplary embodiment, the frame 100 may include purlins 108 that have a curved shape. That is, the purlins 108 that connect the structural members 106 to an adjacent structural member can have a curved shape. Curved purlins are advantageous for pushing snow or water to the curved areas to drain, which reduces the amount of snow build-up and/or water pocketing that can lead to shelter failure or roof collapse. The purlins 108 may be made in a concave or convex configuration. The use of CNC cutting allows for easy manufacturing of purlins 108 having a curved shape (or any other suitable shape).

Referring to FIGS. 1 and 5, an exemplary embodiment of an beam 500 is shown that can be used to make the structural members 106a-g. The beam 500 includes a first flange 502, a second flange 504, and a web 506. In one embodiment, after the frame 100 is assembled, the first flange 502 will be positioned toward an exterior of the frame, and the second flange 504 will be positioned toward an interior of the frame. However, the structural members 106a-g of the frame 100 may be situated such that the beam 500 may be positioned in any suitable manner that allows the frame to support a fabric cover (not shown) of the transportable shelter.

Referring to FIGS. 5 and 6, the web 506 of the beam 500 may take various forms. The form of the web 506 depends on the shape of the structural member 106a-g. That is, as described above, the structural members 106a-g may take several different shapes, and, accordingly, the web 506 of the beam is capable of taking various shapes. For example, the web 506 may take any of the forms 610-615 shown in FIG. 6, or any combination thereon. The web 506 may take a curved form, a polygonal form, forms having varying widths, etc. In an exemplary embodiment, the web 506 may take the form shown in FIG. 5. That is, the web 506 may include opening(s) 510, which is advantageous because it reduces the amount of material needed to make the web. In addition, the different forms 610-615 shown for the web 506 in FIG. 6 may also have openings to make the web out of less material. The web 506 may take any suitable form that is capable of making any form of the structural members 106a-g (FIGS. 1 and 2) described in the present application. As described above, the use of CNC cutting makes it easy to manufacture beams 500 having different shapes.

Referring to FIGS. 7 through 9, an exemplary embodiment of the connection between a flange 502 (or flange 504 shown in FIG. 5) and the web 506 is made using a barrel fastener 708 and a bolt 710. Referring to FIG. 8, an exemplary embodiment of a barrel fastener 708 includes a threaded opening 712. Referring again to FIGS. 7 through 9, the barrel fastener 708 is attached to the web 506 such that an opening 704 in the flange 502 is aligned with the threaded opening 712 in the barrel fastener. In the illustrated embodiment, the web 506 has an opening 706 that is configured to receive the barrel fastener 708. In certain embodiments, retaining rings (not shown) are used to secure the barrel fastener 708 to the web 506. However, the barrel fastener 708 may be secured to the web 506 in any suitable manner that allows the treaded opening 712 of the barrel fastener to be aligned with the opening 704 of the flange 502. The bolt 710 is placed through the opening 704 in the flange 502 and threaded into the threaded opening 712 of the barrel fastener 708 to secure the flange 502 to the web 506.

In certain embodiments, the bolt 710 is permanently connected to the barrel fastener 708. In alternative embodiments, the bolt 710 is semi-permanently connected to the barrel fastener 708. Whether the bolt 710 is permanently connected or semi-permanently connected depends upon the needs of the user. In embodiments in which the bolt 710 is semi-permanently connected, the semi-permanent connection allows individual member pieces (e.g., flange 504, web 506, etc.) to be removed and replaced, which is advantageous in situations in which a member piece requires replacement. In certain embodiments, during the assembly process, a liquid thread lock can be applied to the threads (not shown) in the opening 712 of the barrel fastener to make the connection between the bolt 710 and the barrel fastener 708 permanent. In alternative embodiments, the threaded connection between the bolt 710 and the barrel fastener 708 may be made permanent by mechanically altering the thread pitch of the threaded opening 712 of the barrel fastener. That is, the mechanical altering of the thread pitch of the threaded opening 712 can cause friction lock between the threaded hole 712 and the bolt 710 (which would have a standard pitch thread).

In addition to securing the flange 502 to the web 506, a barrel fastener 708 and bolt 710 can be used to secure any member piece to another member piece. For example, the barrel fastener 708 may be used to connect a beam (e.g., beam 500 shown in FIG. 5, beam 1100 shown in FIG. 11, or any other embodiment of a beam) to one or more reinforcement components, one or more accessory components, etc.

In the illustrated embodiment, the barrel fastener 708 has a cylindrical shape. The cylindrical shape of the barrel fastener 708 allows for the barrel fastener to be rotated, which is advantageous in aligning the barrel fastener in the hole 706 of the web 506. The cylindrical shape of the barrel fastener 708 also increases the amount of surface area afforded to the barrel connection, which allows force to be evenly distributed across the surface area of the barrel fastener 708 and hole 706.

Referring to FIG. 10, another exemplary embodiment of the connection between a flange (e.g., flange 502 or flange 504 shown in FIG. 5) and the web 506 is made using T-slot and nut fastener 1008, which includes a nut 1009 and bolt 1010. The nut 1009 is secured in a slot 1007 in the flange 506. The fastener 1008 is attached to the web 506 such that an opening (not shown) in the flange is aligned with a threaded opening in the nut 1009 of the fastener 1008. The bolt 1010 is placed through the opening in the flange and threaded into the threaded opening of the nut 1009 to secure the flange to the web 506.

The web 506 may be secured to the flanges 502, 504 in any suitable manner. For example, in addition to the connections shown in FIGS. 7-10, the web 506 can be secured to the flanges 502, 504 by saddle fasteners, angle bar fasteners, a rivet connection, etc.

Referring to FIGS. 1 and 11-12, another exemplary embodiment of a beam 1100 is shown that can be used to make structural members 106a-g. The beam 1100 includes a first member 1102, a second member 1104, a third member 1106, and a fourth member 1108. While the illustrated embodiment shows four members (1102, 1104, 1106, 1108), it should be understood that less than four members or more than four members may be used. Each of the members (1102, 1104, 1106, 1108) include teeth 1125 and notches 1126. In the illustrated embodiment, the teeth 1125 and notches 1126 of the members (1102, 1104, 1106, 1108) are aligned with the teeth and notches of the adjacent members. In addition, a fastener 1110 is placed through opening(s) 1112 of a parallel pair of the members (1102, 1104, 1106, 1108), and another fastener 1114 is placed through opening(s) 1116 of the other parallel pair of the members and the fastener 1110 to connect the members and create the beam 1100. The beam 1100 may be used in any of the embodiments described herein regarding the structural members 106a-g.

Referring to FIGS. 2 and 13-21, the interconnecting portions 212a-f of the structural members 106a-g are connected to adjacent interconnecting portions at connection points B-F. In an exemplary embodiment, the interconnecting portions 212a-f are connected by a hinge assembly 1300. FIG. 13 illustrates interconnecting member 212d connected to interconnecting member 212e at connection point E. The hinge assembly 1300 includes a connection portion 1302 and a receiving portion 1304. The receiving portion 1304 is configured to receive the connection portion 1302, and the receiving portion is connectable to the connection portion such that the connection between the portions can be a pivotable connection or a fixed connection. In the illustrated embodiment, the receiving portion 1302 of the hinge assembly 1300 is attached to interconnecting member 212d and the connection portion 1304 of the hinge assembly 1300 is attached to interconnecting member 212e. In an alternative embodiment, the connecting portion 1304 can be attached to interconnecting member 212d, and the receiving portion can be attached to interconnecting member 212e.

Referring to FIGS. 1-2 and 13-17, the capability of moving the connections between interconnecting members 212a-f of structural members 106a-g between pivotal connections 1600 and fixed connections 1700 is advantageous because a fixed connection 1700 can be utilized when the structural members are in a standing position (as shown in FIGS. 1 and 2), but the pivotal connections 1600 can be utilized to fold the interconnecting members over each other to reduce their size when the structural members are in storage or being transported.

While the connection between interconnecting portions 212a-f of structural members 106a-g at connection points B-F is shown using hinge assembly 1300, it should be understood that the interconnecting portions 212a-f may be connected in various ways, such as, for example, by slip-joint plate connectors, by solid bolting connections, etc. In addition, while the above-mentioned connections are described with reference to connection points B-F shown in FIG. 2, it should be understood that the above-mentioned connections may be utilized at any connection point between interconnecting members, and the number of connection points depends upon the number of interconnecting members.

Referring to FIGS. 42A-42D, an alternative embodiment of hinge portion 4200 is shown that has the same function of the connection portion 1302 and receiving portion 1304 of hinge assembly 1300, but is made of a single member rather than from multiple hinge plates 1408, 1516 and spacer plates 1406, 1514. The hinge portion 4200 includes a main body 4201, four hinge protrusions 4202 that extend from the main body 4201, and three slots 4204 disposed between the hinge protrusions 4202. However, the hinge portion 4200 can include any number of hinge protrusions 4202 and slots 4204. In addition, the hinge portion 4200 includes a pair of apertures 4210, 4218 for receiving a fastener (not shown). In an exemplary embodiment, the apertures 4210, 4218 extend through the hinge protrusions 4202. In some embodiments, the main body has one or more apertures 4212. A fastener is placed through the flange (e.g., flanges 502, 504 shown in FIG. 5) of a beam (e.g., beam 500 shown in FIG. 5) and through the apertures 4212 of the hinge portion 4200 to secure the hinge portion 4200 to the beam. While the illustrated embodiment shows the hinge portion 4200 having four apertures 4212 for securing the hinge portion 4200 to the beam, it should be understood that any number of apertures can be used to secure the hinge portion 4200 to the beam.

In certain embodiments, the hinge portion 4200 has a slot 4215 configured to receive the web of the beam when the hinge portion 4200 is secured to the beam. In some embodiments, the main body 4201 has connection channels 4213 to secure the hinge portion 4200 to the web of the beam. The connection channels 4213 intersect the apertures 4212 (as shown in FIG. 42C). In addition, a fastening member 4220 (FIG. 42D) is configured to be inserted into the connection channels 4213. The fastening member 4220 includes a pair of apertures 4216 that align with the apertures 4212 of the main body 4201 when the fastening members 4220 are inserted into the connection channels 4213. In this embodiment, when the web of the beam is placed in the slot 4215 of the main body 4201, the fastening members 4220 are inserted into the connection channels 4213 of the main body 4201 such that the fastening members extend through an opening (not shown) in the web. Subsequently, a fastener (not shown) is inserted through the apertures 4212 of the main body 4201 and the apertures 4216 of the fastening members 4220 to secure the hinge portion 4200 to the beam.

Still referring to FIG. 42A, the hinge portion 4200 is created by extruding a single piece of material 4230 having the apertures 4210, 4218, 4212, the slot 4215. In the illustrated embodiment, the single piece of material 4230 has the shape shown in FIG. 42C (which is the same shape of the hinge plates 1408 of the connection portion 1302 shown in FIG. 14). However, the single piece of material 4230 may have any suitable shape for making a hinge portion for a hinge assembly. Referring to FIG. 42B, after the single piece of material 4230 is extruded, the hinge portion 4200 is created by machining the single piece of material to include the slots 4204 and drilling the single piece of material to include the connection channels 4213. It is advantageous to create hinge assemblies using the hinge portion 4200 because the extrusion of the single member 4230 makes it easy to make hinge portions having various lengths, as well as various amounts of hinge protrusions 4202 and slots 4204.

In an exemplary embodiment, the hinge portion 4200 can be machined to take a similar form to the connection portion 1302 of hinge assembly 1300, and another hinge portion 4200 can be machined to take a similar form to the receiving portion 1304 of the hinge assembly 1300.
