Modular frame and enclosure system
The invention is a modular frame system that can be used to construct free-standing enclosures for equipment. The modular system includes interchangeable frame members connected to transition members that can together be arranged to form an orthogonal frame. Other accessory components can be attached to build an enclosure system. The invention envisions utilizing composite materials in constructing enclosures, with such embodiments having an enhanced strength to weight ratio. The frame system is constructed of frame members that facilitate alignment and attachment of other system accessory components through use of regularly spaced upstanding male connectors that engage with regularly spaced depressed female connectors. Thus, there is great flexibility in attachment of components and adapting the enclosure system to particular applications. Frame members of the invention can alternatively be used as construction components in a variety of building systems.

STATEMENT REGARDING FEDERALLY SPONSORED RESEARCHNot applicable.
BACKGROUND OF THE INVENTIONEnclosures are used for a number of applications, including three general categories: to provide environmental protection of equipment; to provide a rack or mounting space in which to mount equipment such as computer equipment; and to enclose controls for the utility and energy industries. The enclosure industry is very broad in terms of specific enclosure applications and configuration of the enclosure to house particular products. Broad categories of product configurations include large freestanding units, wall mount units, junction boxes, instrument housings, consoles, operator interfaces and kiosks.
The market in the United States alone for industrial enclosure applications is estimated to exceed $1 billion annually, with approximately half of the dollar value consisting of free-standing enclosures. The general form of most enclosures is orthogonal, either square or rectangular in cross section, although for certain applications other cross sectional shapes may be useful, including trapezoidal, hexagonal and octagonal.
Other variations on the basic form of an enclosure embodied by the freestanding enclosure include wall mounted boxes, operator interface cubicles, along with accessory products such as swing frame mounting panels, doors, partitions and wire way. Many enclosure systems are designed to conform to the Electronic Industry Association 310c standard for hole spacing and location to allow for mounting standard 19 inch equipment on rails (EIA rail).
One difficulty for manufacturers is shipping enclosures is that an assembled enclosure has a very high space to weight ratio. Therefore shipping and handling of assembled enclosures is problematic, as shipping assembled enclosures requires substantial volume. As manufacturers attempt to ship more compact, disassembled components to order minimize shipping costs, there is an efficiency trade-off for the end user, who must either pay to have a technician assemble the enclosure, or assemble the enclosure on site, where time, tool availability, and mechanical skill may limit the ability of the end user to configure an enclosure product in an optimal manner.
As many end users who have attempted to assemble an unfamiliar enclosure or other furniture can attest, basic unfamiliarity of the method of assembly of a complex product of many unfamiliar parts can be a frustrating and often laborious process.
For these reasons modular enclosure construction styles have proven popular because of ease of assembly and ready access, flexible configurations, and capability of expansion. Performance of enclosures utilizing modular construction is limited relative to “unibody” free-standing enclosures with regards to structural rigidity, weight capacity, and other logistical requirements. Some of these limitations of modular construction technology can be eliminated by adding structural reinforcements, usually through adding selected accessory products at additional costs in weight, labor and acquisition price.
A variety of materials have been used to construct enclosures. Freestanding enclosures have utilized mild carbon steel, stainless steel, aluminum and fiberglass reinforced polyester. Considerations on determining the material used in an enclosure include the weight of the enclosure, with heavier materials limiting portability; the weight bearing capacity of the enclosures, with steel being typically used for enclosures carrying heavier loads; and corrosion protection, with enclosures being used in corrosive environments being constructed of stainless steel or polyester.
A number of other performance versus cost balancing factors may be considered when determining the material used and the construction method depending on the particular enclosure application These factors include ease of assembly, need for electromagnetic interference (EMI) shielding, shock and vibration resistance, requirement for explosion protection, enclosure accessory requirements, thermal management, vandalism resistance, hygiene, environmental protection ratings, electrical properties, and industry standards and municipal codes.
Recently, hybrid materials have been developed that combine metal support members with integrated plastic reinforcements. See U.S. Pat. No. 5,190,803 and 6,421,979, the disclosures which are incorporated herein by reference.
There is a need in the enclosure industry for enclosures exhibiting high strength to weight ratio, user configurable structure, capacity for environmental protection and environmental control and relative ease of assembly. The invention disclosed herein offers advantages in many areas important for the design and performance of an enclosure system. When embodied through the use of composite construction, including metal/plastic hybrid material, there are advantages in strength to weight ratio and enabling the optimization of material properties for a particular application. Additionally the modularity of construction, ease of alignment, and utilization of materials with a high strength to weight ratio have applications in many areas of the furniture, construction and other industries.
BRIEF SUMMARY OF THE INVENTIONThe present invention is directed to a method for producing modular frames that have wide application in the furniture, enclosure, construction and other industries. One embodiment provides a rigid rack system that can serve as the frame for freestanding enclosures and if used in conjunction with other modular components of the invention, can be used to construct secure freestanding enclosures for electronic and other equipment.
The invention is embodied in a method of making a frame comprising the steps of providing two or more linear frame members exhibiting frame contact peripheries at the ends and a frame cross-section presenting at least one contact edge along the axis of the frame edges. An additional embodiment of the invention are one or more transition members that form a junction and or corner connection between linear frame components. Ideally, the transition member will exhibit a contact periphery in at least two contact planes. The invention is embodied in aligning a frame contact periphery of a frame member with a first edge profile and abutting a linear frame member to a first contact surface of a transition member, aligning a frame contact periphery with a second edge profile and abutting a linear frame member to a second contact surface of a transition member and then aligning a frame contact periphery with a third edge profile and then abutting a linear frame member to a third contact surface of a transition member. By reiterating the aligning and coupling steps, a three dimensional frame can be constructed according to the invention, utilizing transition members with four or more contact surfaces.
The invention is embodied in a means for connecting and aligning transition members and frame members by providing one or more stud connectors each having first and second connector portions in a more or less linear orientation. Linear frame members are provided with two or more with frame connector cavities extending axially and mutually inwardly from the frame contact ends. Another embodiment of the invention is the connection of frame members to transition members each being configured with a transition connector cavity extending axially inwardly from first, second, third and or fourth contact surfaces. Thus the steps of aligning and coupling a transition member with frame members can be carried out by inserting a stud connector first connector portion within a frame connector cavity and inserting said stud connector second connector portion within a said transition connector cavity. Alignment and permanent connection are embodied in the use of connector clips and locking spacer collars.
The invention is also embodied in a transition member or frame member being configured having an outwardly disposed flat surface having one or more frame carrying connectors, or nubs, integrally formed with the flat surface. Frame members can be configured with regularly spaced carrying connectors, with the carrying connectors lending modularity to the frame members of the invention. The steps of aligning and coupling a frame member locates the frame member and or a transition member with the outwardly facing flat surface that is aligned, thus providing for attachment of a corner completing accessory of the invention, in one embodiment having a cross-section of triangular shape to define a corner by interconnecting frame carrying connectors with accessory connectors. The invention is also embodied in a system and method in which one or more frame members with one or more flat surfaces having an array of said frame carrying connectors which are outwardly depending male connectors and providing an accessory component with accessory carrying connectors as inwardly depending female connectors. The invention is furthermore embodied in a system and method in which one or more frame members with one or more flat surfaces having an array of said frame carrying connectors which are inwardly depending female connectors and providing an accessory component with accessory carrying connectors as outwardly depending male connectors.
According to the invention is a method for aligning and coupling two or more frame members or other frame components with one or more transition members carried out to derive a frame structure with two or more adjacent bays where two vertically oriented frame members are located with a linear edge of one frame member abutting a linear edge of the adjacent frame member. Thus, the cross section of each frame is, in a preferred embodiment, generally square to provide two angularly oriented frame faces extending outwardly from the abutting linear edges. The adjoining frames can be sealed by installation of a resilient gasket and by further providing an inter-bay completing accessory having a cross-section of triangular shape and having accessory connectors corresponding with an array of frame carrying connecters, thus coupling the inter-bay completing accessory at the respective side faces to the angularly oriented frame faces by interconnecting frame carrying connectors with accessory connectors.
Another embodiment of the invention is a frame constructed according to the invention that possesses continuous transition edges, capable of forming a tight seal, especially when employed with a gasket of resilient material. Furthermore, frame systems of the invention can be stacked vertically, and connected in a manner analogous to the horizontal connection just described.
The invention is further embodied in frame members whose frame cross-section defines four flat orthogonally disposed surfaces with one or more said flat surfaces having a said frame connecter assemblage comprising an array of frame connectors, with each transition member back surface frame carrying connector assemblage comprises an array of said frame connectors. The frame connectors are embodied as outwardly depending male connectors and the accessory connectors are embodied as inwardly depending female connectors. Additionally, the frame connectors are embodied as inwardly depending female connectors and the accessory connectors are embodied as outwardly depending male connectors. In a preferred embodiment of the invention the frame cross-section is rectangular or substantially square, although other cross-sectional shapes can be used to practice the invention.
The invention is embodied in a frame system, comprising a plurality of linear frame members of given lengths extending along a frame axis between oppositely disposed contact ends, with the contact ends exhibiting frame contact peripheries. The frame system may include a plurality of transition members. The frame possesses a plurality of transition members being designated lower frame transition members, and a plurality being designated upper frame transition members, a plurality of the frame members being designated vertical frame members, and a plurality being designated horizontal frame members.

Yet another embodiment of the invention are frame members configured having an open channel extending between frame component ends. Frame members can be designed to function independently as modular construction elements, including as conduits, or with a design specialized for construction of a modular frame system. Frame members and transition members can be configured according to the invention having joined open channels with the transition member cavities being generally aligned with a frame cavity when their respective contact peripheries are aligned. The frame system is also embodied in one or more of said frame members comprising a generally U-shaped channel component having an outwardly open cap receiving side and configured with a generally U-shaped reinforcing member having three outwardly disposed frame faces and a reinforcing member cavity extending between the oppositely disposed contact ends. Preferably, a polymeric channel matrix member is located within the reinforcing member cavity configured to define a portion of the frame connector cavities extending inwardly from the frame contact ends and further configured to define a matrix bottom wall and side walls extending outwardly to spaced apart cap engagement ledges adjacent to the outwardly open cap receiving side. A cap component is provided, configured for positioning over the aforementioned channel component open cap receiving side and having a generally flat cap reinforcing member with an outwardly disposed frame face and an inwardly attached polymeric cap matrix member having oppositely and axially disposed spaced apart engagement surfaces engaging said spaced apart cap engagement ledges, the cap matrix member, with the channel matrix member, defining the frame connector cavities. A connector assembly coupling said cap component with said channel component, including manifold blocks to direct airflow and provide access to the frame member cavity are provided. Although a frame member with a square cross-section in mentioned as a preferred embodiment, other cross-section of frame members can be used to practice the invention.
Other objects of the invention will, in part, be obvious and will, in part, appear hereinafter. The invention, accordingly, comprises the apparatus and method possessing the construction, combination of elements, arrangement of parts and steps which are exemplified in the following detailed description.
For a fuller understanding of the nature and objects of the invention, reference should be had to the following detailed description taken in connection with the accompanying drawings.
BRIEF DESCRIPTION OF THE DRAWINGS
The invention is embodied in a modular frame system that can be used to construct free standing enclosures for equipment. In the discourse to follow an enclosure is generally described which incorporates the frame system and method of the invention. Then, the uniquely developed frame system is described including the utilization of linear framed members and transition members which function to define corners as well as to evolve continuous transition edge which falls within a common transition plane permitting an ideal sealing of the cavity defined by the enclosure. The discussion then turns to the structuring of the frame and transition members as they are combined to form an enclosure. To achieve a continuous edge within each transition plane the frame members are rotated in effect an amount of about 45°. However, to reconstitute the sides or skin of an enclosure, accessories are provided which, in effect, return frame surfaces to a conventional orientation. The frame system is constructed of frame members that facilitate alignment and attachment of other system components, such as sealing panels, hinged doors, shelves, drawer tracks, or decorative panels.
The modularity of the components of the invention is illustrated by the interchangeability of horizontal and vertical frame members. While it is possible to construct horizontal and vertical frame members of the invention with different cross sections, for instance with rectangular and round cross sections respectively, modularity and interchangeability of system components is enhanced by producing horizontal and vertical frame members with the same cross section, for instance a square cross section.
In a preferred embodiment, all frame members or frame member components are hollow. When a frame is assembled from hollow frame members, studs, and manifold blocks, there will exist a frame cavity that forms a continuous passageway throughout the structure of the assembled frame. This hollow construction facilitates the application of a number of accessory elements to adapt the assembled frame for a particular application.
Frame members can be cast, molded or extruded from a wide range of materials including thermoplastics and thermoset compounds such as polyamides, polyethylene, polysulfones, polycarbonates, polystyrene, polyester or vinyl resins, epoxy resins, and phenolic resins including copolymers and blends and these materials in reinforced or filled form or from other materials known to those skilled in the art, depending on the requirements of a particular application. Materials to fill, reinforce or modify the above materials include fibers or woven fabrics of glass carbon or textiles and modified natural substances such as wood particles and mineral fibers. Frame members or particular components could be milled or formed, including from metals such as steel, stainless steel, aluminum, and titanium and alloys of these or other appropriate metals.

One embodiment of the invention is the relative orientation of the transition edges of different frame members. One advantage of threaded connector studs as in 140 along with locking spacer collars as in 166 is the capability to install frame members in a chosen orientation relative to one another. In a further embodiment of the invention, other shapes of frame members can also be oriented relative to the transition members to expose an outwardly facing transition edge, disposed in a plane. By adjusting the orientation of frame members through use of connector studs and locking spacer collars, frame members of triangular, rectangular, pentagonal, hexagonal, or octagonal cross section can be oriented to expose a sealing edge in a plane. Certain cross sections of frame members can also be oriented to expose an inwardly facing sealing edge.
Now looking to the transition members as at 70, each is typically formed with four cognitively disposed components. The first such component is represented generally at 112 and is seen to be disposed about a vertically oriented first axis identified at 114. Component 112 provides a first contact surface 116 which exhibits an edge profile which corresponds with the earlier-noted frame contact periphery. That edge profile is oriented about the first axis 114 to position two opposite edges within a first plane extending through the axis 114.
Transition member 70 further is configured having a second component 118 extending along a second axis 120 to a second contact surface 122. Surface 122 exhibits an edge profile corresponding with the cross-section of frame member 49 and is oriented about the second axis 120 to position two opposite edges and a second plane normally disposed with respect to the noted first plane. One of those edges has been described at 96. The figure permits the illustration of this second plane as at 124.
Not seen in this figure is a third component extending along a third axis represented at 128. That component is oriented about axis 128 such that two opposite edges, one of which has been described at 110 lie within the earlier-noted second plane 124. Finally, a fourth component is represented generally at 130 extending along the first axis 114 opposite the first component to a fourth contact surface represented generally at 132. Surface 132 exhibits an edge profile corresponding with the cross-section, for example, of foot or frame member 82. Now looking to the transition edges of transition member 70, note that an outermost one of two edges as shown at 134 with respect to the first and second components interact with contact surfaces 122 and 116 in continuous fashion and within a transition plane. Note that this edge exhibits a medial curvature as represented generally at 136. It may be observed that the outermost edges 98 of the first frame member 42 and the corresponding outermost edge 96 of frame member 49 define a continuous transition edge within a common transition plane. A similar geometry is present with respect to each of the four transition member components. In those situations where less than four frame member components are to be joined, transition members can be constructed with two, or three, cognitively disposed components. The figure further reveals the presence of connector screws certain of which are identified at 138.
In a preferred arrangement, the linear frame members are interconnected with the transition members utilizing stud connectors. Looking to

Another embodiment of the invention is as a hollow construction element. When a hollow construction element is formed from composite materials as described the construction element of the invention can be used to construct wireway conduit that can be used separately, or in conjunction with the frame system and enclosures of the invention.

Note that screw ports, certain of which are identified at 222 extend through the sides of the frame member for communication within the frame connector cavity portion 210. Such screws are represented, for example, at 138 and correspond with screws as described at 138 in
Certain stud connectors as represented generally at 226 are coupled within the frame connector cavity. In this regard, the first connector portion 228 of stud connectors as at 226 is mounted within the frame connector cavity utilizing generally U-shaped retaining clips. In this regard, two lower disposed such clips are shown at 232 and 234 which are located within respective matrix clip channels 239 and 238. Corresponding matrix clip channels are shown at 240 and 241. Those channels are aligned with the inner and outer stud connector clip channels here identified in connection with stud 226 at 236 and 237. Those channels are seen to be in alignment with inner and outer cap channels 240 and 241. Corresponding inner and outer cap clip channels are shown at 243 and 244. These cap channels receive upper retaining clips 231 while the said channels additionally are retained by lower retainer clips (not shown) but as described above at 232. Retaining clips are shown as separate parts of two pieces, which would allow retaining clips to be made of a different material than the attachment stud. In the alternative, connector stud 226 can be formed with an integral rib shaped to fit the retaining clip channel of frame member channel component 192 and frame member cap component 224.
A manifold block also may be located within the frame cavity. One such manifold block is represented generally at 250 and is shown configured with six mutually communicating threaded openings. Three of those openings are shown at 252-254. Depending on the length of the frame member and any requirements for additional reinforcement or modifications of an assembled frame member, one or more of manifold block 250, when inserted and aligned with one of the screw ports 222 may be connected in position by machine screws as at 138 to provide intermediate structural support for the linear frame member. Manifold block 250 can be made with one or more threaded holes 252, or could be solid.
The frame member shown in
Returning to the cap 224, a configuration is illustrated which includes a generally flat frame cap reinforcing member 256 which preferably is formed of metal and exhibits an outwardly disposed frame face 258 and an inwardly attached polymeric cap matrix member 260. Matrix member 260 is configured having oppositely and axially disposed spaced apart engagement surfaces 262 and 264 configured to engage respective cap engagement ledges 218 and 220. The cap 224 is assembled against the cap receiving sides 194 through the utilization of connector screws, certain of which have been identified at 138 which extend through ports as at 225 extending through the cap. These screws will engage the threaded openings in oppositely disposed stud connectors as described earlier at 160. Frame member channel component 194 will typically have screw holes 222 aligned with the threaded holes 160 of connector stud 226, and screws 138 can likewise be driven into the connector stud to reinforce the retention of the connector stud in the frame member. The frame member channel component, connector stud and frame member cap component can also be assembled alternatively, or additionally, using an adhesive or other joining means. Additionally, intermediately disposed screws may be threadably engaged with one or more interval manifold blocks at 250. When joined, the frame member channel and frame member cap will form a frame member with a rectangular cross section, although the invention can be practiced with frame members of a number of different cross sections.
As described above, the linear frame members as at 190 are of a hybrid nature combining a polymeric matrix with a metal exterior. The members further are configured with an array of outwardly depending polymeric male connectors or nubs, certain of which are identified at 248. These connectors will be seen to be configured in a variety of shapes and materials. The outwardly disposed surfaces of frame members can be embodied to carry nubs or outwardly disposed male frame carrying connectors 248. As explained in greater detail below, the outwardly disposed male connectors will in preferred embodiments serve a dual role, serving both as a means to fix the polymeric matrix component to frame reinforcing members and also as a means of connecting accessory components.

The figure reveals that a top panel 336 is affixed over the top of the assemblage. In this regard it extends over the back surface 338 of transition member 302. Note that a polymeric seal 340 has been located between the transition edge 330 and the inward side of top panel 336.
Now looking to the lower portion 282 of the assemblage, a lower horizontal frame member is represented generally at 342. As before, frame member 342 is assembled within the system by aligning its contact end 344 with the corresponding contact surface 346 of transition member 304. A rigid connection is established through the utilization of stud connector 348, which connection can be further secured in a given orientation by the engagement of locking spacer collar 349. As before, the horizontal frame member 342 is shown with transition edges 350 and 352 which surmount polymeric matrix component 354.
In another embodiment of the invention, to facilitate temperature regulation of the enclosure, environmentally conditioned fluids can be introduced into the frame cavity as at 292 in

An advantage of having the frame carrying connectors composed in part of a frame reinforcing member is the increased strength of carrying connectors, and resistance to wear typically found in materials utilized in the frame reinforcing member compared to the polymeric matrix component. Other portions of frame members and accessory members can be similarly configured.

Bay 422 is attached to bay 424. Looking to bay 424 it is seen to be formed of four vertical columnar supports 480-483. In this regard, the inverted back surfaces 486-489 of upper transition members are revealed at the four corners of the bay. Extending between vertical frame member 483 and vertical frame member 480 is an upper horizontal frame member 492. Three of the transition edges of this member 492 are revealed at 493-495. Note that transition edge 493 falls within the transition plane 462.
Extending between vertical supports 480 and 481 is an upper horizontal frame member 498. Three transition edges 499-501 are represented in the figure. Note that transition edge 499 falls within a central transition plane 504. The figure also reveals that transition edge 452 of horizontal member 450 is essentially coplanar with that transition plane. An upper horizontal frame member 506 is seen to extend between vertical supports 483 and 482. Member 506 also is illustrated with three transition edges 507-509. Note that transition edge 507 falls within a side transition plane 512. Finally, an upper horizontal frame member 514 interconnects vertical support 481 and 482. Further, three transition edges 515-517 are revealed and it may be noted that transition edge 515 is coplanar with transition plane 460.
Corner completing accessories 520 and 522 having a triangular cross-section are mounted to the orderly disposed surfaces of vertical supports 482 and 483. These corner accessories provide a flat corner surface. In this regard, the flat surface of accessory 522 is shown supporting a hinge 524 of a door 526. Similar to bay 422, bay 424 incorporates vertical accessory supports 528 and 530 which are attached to one face of the vertical corner supports 480 and 483. Connected to those support accessories 528 and 530 is a vertical support panel 532 upon which is mounted electrical equipment represented at block 534.
The supporting frames of base 422 and 424 are juxtaposed to define those two bays such that the rearward vertically disposed corner region of support 429 abuts a corresponding rearward vertically disposed corner region of support 480. This develops two rearward angularly outwardly oriented frame faces 536 and 538 which define a rearward outwardly extended space of triangular cross-section.
In the same manner the forward vertically disposed corner region of vertical support 428 abuts the forward vertically disposed corner region of support 481. This provides two forward angularly outwardly oriented frame faces 540 and 542 defining another rearward outwardly extending space of triangular cross-section. Coupled between the frame within these spaces are inter-bay completing accessories having a cross-section of triangular shape corresponding with the spaces of triangular cross section. Thus, an inter-bay completing accessory 544 connects vertical components 480 and 429 and a corresponding inter-bay completing accessory 546 connects the vertical supports 428 and 481.
A back panel 548 is seen to extend across the combined bays 422 and 424 and is sealed to the frame members as represented at seal 550 at bay 422. In similar fashion, seal 552 engages back panel 548 at bay 424. In similar fashion, a seal 554 engages a side panel 556 at the right side of the enclosure 420 as represented in the figure. A left side panel 558 is sealed to the bay 424 at seal 560. Next, a seal 562 located at transition plane 504 sealably supports the inter-bay connection. Note, additionally, door 526 contacts a continuous seal as represented at 564 which engages the transition edges adjacent the forward transition plane 460.
As described above, the surfaces of the frame members of the invention can be constructed to expose regularly spaced male carrying connectors, as at 88, on the faces of the frame members. The spacing of male connectors facilitates attachment and alignment of accessory component members female connector sockets.
