DETAILED DESCRIPTION OF THE EMBODIMENTS
The different aspects of the various embodiments can now be better understood by turning to the following detailed description of the embodiments, which are presented as illustrated examples of the embodiments as defined in the claims. It is expressly understood that the embodiments as defined by the claims may be broader than the illustrated embodiments described below.
The inventor has discovered a novel modular framing system for any conceivable structure that requires the use of some kind of underlying framing or truss.
In one aspect, the inventor has discovered that when prior art extrusion parts are under stress, their external lips almost always experience a larger deformation and more displacement than the center portion of the extrusion. The inventor has discovered that the external lips (see FIG. 7) are not the best location to mount fixtures.
Referring now to FIG. 1A, the contemplated system 100 (see FIG. 15 as one example) of modular frame structure includes one or more support pillars 110 all of which can act as a major backbone of the modular frame structure. FIG. 1A shows a terminal end of the contemplate support pillar 110. Here, the support pillar 110 can generally have an octagonal cross-sectional shape. In some embodiments, the support pillar 110 can have an octagonal cross-sectional shape but the disclosure is not limited thereto. In some embodiments, the support pillar 110 can have a square or rectangular cross-sectional shape but the disclosure is not limited thereto. In some embodiments, the support pillar 110 can have a circular cross-sectional shape but the disclosure is not limited thereto. In some embodiments, the support pillar 110 can have a polygonal cross-sectional shape but the disclosure is not limited thereto. In some embodiments, the support pillar 110 can have a symmetrical polygonal cross-sectional shape but the disclosure is not limited thereto.
As used herein, the term “support pillar” is sometimes referred to in the industry as an aluminum extrusion. It should be particularly noted that the support pillar may be made of aluminum or other materials and can be manufactured by way of extrusion or other means. For example, the support pillar 110 can be formed by extrusion, casting, CNC machining, or other known shaping methods. The materials of the support pillar 110 can be metal, ceramic, plastics, composite materials, any natural or synthetic material, and any mixture of the above materials. Additionally, the support pillar 110 may be surface treated by any known methods such as sandblasting, anodizing, and by any known heat treatment methods such as T6 and T651. Any other combination of known surface treatments and heat treatments are particularly contemplated to strengthen any threaded holes.
Depending on the intended uses, any of the contemplated parts in this disclosure can be made of a suitable material to withstand temperature extremes and chemical extremes, such materials include natural and synthetic polymers, various metals and metal alloys, naturally occurring materials, ceramic materials, and all reasonable combinations thereof.
In FIGS. 1A-1E, the support pillar 110 generally has a main body 112 through the entire length of the support pillar 110. Radiating from the main body 112 there can be a plurality of channel walls 120. Each channel wall 120 can have a length from one terminal end of the support pillar 110 to the opposite terminal end of the support pillar 110. In some embodiments, the channels walls 120 are equally spaced apart from each other.
In some embodiments such as those shown in FIGS. 1A, 1B, 1D, the support pillar 110 is contemplated to have a center bore 114 that spans through the entire length of the support pillar 110. In other words, the center bore 114 can be a hollow space within the main body 112 from one terminal end of the main body 112 to the opposite terminal end of the main body 112. At each terminal ends of the main body 112, the center bore fluidly connects to the outside environment via an opening such as the octagonal shaped opening in FIG. 1A. FIG. 1D is a view of a terminal end of the contemplated support pillar 110 showing an octagonal shaped opening of the center bore 114.
In one embodiment, a user may use the center bore 114 for cable or pipe management. As will be described below, the center bore 114 may also receive one or more core connectors 140 (see FIG. 2).
In some embodiments such as that shown in FIG. 1E, the support pillar 110 is contemplated to have a main body 112 that is entirely solid and without any center bore 114. FIG. 1E is a view of a terminal end of a contemplated support pillar 110 showing the main body 112 having a solid center without any center opening for a center bore 114.
Whether or not the center bore 114 is present, the main body 112 is contemplated to have at least one row of consecutive holes 117 disposed lengthwise on the main body 112 in between two adjacent channel walls 120. As for the embodiment specifically shown in FIG. 1A, each of the holes 117 can be through holes disposed through the thickness of the main body 112 such that the center bore 114 can be fluidly connected to the space in between two adjacent channel walls via the through hole 117.
In another embodiment now shown in the figures, the row of consecutive holes 117 disposed lengthwise on the main body 112 cannot be through holes. For example, the holes 117 can be sufficiently shallow so each hole does not open through to reach the center bore 114. In still another embodiment where the main body 112 of the support pillar 110 has no center bore 114, the row of consecutive holes 117 cannot be through holes.
Also, in any of the embodiments discussed, these holes 117 on the channel floor 123 can be threaded or non-threaded holes. There can be any number of threaded/unthreaded holes. The threaded holes can include any known thread inserts or thread protections.
As shown in FIGS. 1B and 1C, a support pillar 110 is contemplated to have a length. The length of the support pillar 110 would be determined by each particular use. Therefore, the manufacturers can product support pillars 110 over various lengths to fulfill various uses. In the perspective view of FIG. 1B and side view of FIG. 1C, only one row of holes 117 are shown due to their angle of view. For an octagonal-shaped main body, there can actually be up to eight rows of holes 117 each row being disposed between two adjacent channel walls 120.
Referring now to FIG. 1D, the plurality of channel walls 120 can be disposed and equally spaced apart on the main body 112. The channel walls 120 radiate from the main body 112 and two adjacent channel walls 120 form a channel 121. A channel 121 is contemplated to be a track with two terminal ends being open at the two respective terminal ends of the support pillar 110. The top of each channel 121 is also open to the ambient environment via a channel opening 125. Channel opening 125 can have a width defined by the distance between two opposing the external lips. In other words, the channels 121 in the embodiments shown are similar to a trough having an elongated narrow configuration with an open top. In some embodiments, all of the contemplated channels cannot be closed channels (e.g., with its top being closed to the ambient environment). In some other embodiments, at least one of the channels can be closed while others remain open.
Each channel 121 can have a channel floor 123 which can be the outer surface of the main body 112. As described above, there can be a row of consecutive holes disposed on the channel floor 123.
Each channel wall 120 can have an expanded end 130. Various shapes are contemplated for the expanded end 130. In FIG. 1D, the expanded end 130 can be two extending external lips 122. Each external lip 122 can extend in a transverse direction from the radiating direction of the channel wall 120. On the outer side of each external lip 122 there can be disposed a striation 138 or groove. The striation 138 can minimize slippage of accessories attached to the support pillar 110.
The general cross-sectional shape of a channel 121 is defined by the shape of the channel floor 123, the channel wall 120, and the external lip 122. In FIG. 1D, the channel 121 has a cross-sectional shape of a trapezoid. Other shapes are also possible.
Referring now to FIG. 2, which illustrates a connecting core 140. A connecting core 140 can have a cross-sectional shape and configuration that corresponds with the center bore 114 of the support pillar 110. The connecting core 140 is also contemplated to have other cross-sectional shapes such as circular, square, or other polygonal shapes even if its shape does not correlate with the shape of the center bore 114. For example, a round connecting core 140 can be used to receive within an octagonal center bore 114, especially if the diameter of the round connecting core 140 can adequately fit within the octagonal center bore 114 with a small or minimum tolerance. FIG. 16 discloses another embodiment of the main body 112 such that certain portions of the main body 112 can have a thinner profile. The thinner profile at various locations can reduce the overall weight, amount of material used, and/or cost of production. In turn, the cross-sectional shape of the center bore 114 may have outwardly radiating tips.
The connecting core 140 can have various lengths. In one embodiment, it can be much shorter than the length of the support pillar 110. In another embodiment, it can be about the same length as the support pillar 110. In yet other embodiments, it can be longer than the length of a support pillar 110.
The connecting core 140 shown in FIG. 2 has a row of holes 147 disposed consecutively lengthwise. In one embodiment, these holes 147 are equal-distant to each other. In another embodiment, some of these holes 147 are not evenly spaced apart. There can be at least one row of such holes 147. In one embodiment, there can be four rows of such holes 147 to correspond with the rows of through holes 117 on the support pillar 110. In this way, when the connecting core 140 is received either partially or entirely within the center bore 114 of a support pillar 110, the user may use one or more fasteners to secure the connecting core 140 in place. FIG. 3 illustrates one example of having a connecting core 140 received within the center bore 114 of a support pillar 110. The holes 147 shown in FIG. 2 can be threaded or non-threaded holes 147. The holes 147 in FIG. 2 are shown to have a relatively shallow depth thereby exposing the bottom of the holes 147 in FIG. 2. In another embodiment, the holes 147 can be deeper. In still another embodiment, the holes 147 in FIG. 2 can be through holes 147 that thoroughly connects opposite sides of the connection core 140.
FIG. 3 illustrates a support pillar 110 having a main body 112 with a center bore that receives a connecting core 140. Additionally shown in this figure are four binding connectors 150 partially received in their respective channels 121. As will be described below, a binding connector 150 can be fully received into a channel 121 and can freely move within the channel 121 in a lengthwise direction. In other embodiments, a binding connector 150 can not be fully received into a channel 121. As will be further described in other figures such as FIGS. 8A-8C, there can additionally be provided accessories connectors 160 that are similar to the binding connectors 150 in some ways yet different in other ways. A user may freely decide how many binding connectors 150 to use to couple two support pillars 110 end-to-end. In FIG. 3, four binding connectors 150 are used, thereby leaving four other channels 121 free so that any accessories connectors 160 (to be discussed below) located therein can freely slide from one support pillar 110 to an adjacent support pillar 110.
FIGS. 4A-4F show another embodiment of a binding connector 150 each capable of being received within a channel 121 of a support pillar 110. FIG. 4A shows a top view of this particular binding connector 150. There can be two elongated oval shape trough recesses 152 disposed on the top side of the binding connector 150. Each recess 152 can have a bottom floor 154. There can be two through holes 157 disposed on each of the two bottom floors 154. Each through hole 157 can receive a fastener. A fastener such as a screw or a bolt may be inserted into the recess 152 and passed through the through holes 157. The head of the fastener can remain within the recess 152 while the distal end of the shank extends away from the bottom side 156 of the binding connector 150 and into a hole 117 on the main body 112 of the support pillar 110.
FIG. 4B shows a side view of the binding connector 150. Binding connectors 150 can have a straight flat top and a flat bottom side 156. Overall, the binding connector 150 is contemplated to have a cross-sectional shape that corresponds with a cross-sectional shape of the channel 121 such that the binding connector 150 can fittingly receive within the channel 121.
In FIG. 4E, four binding connectors 150 are partially inserted into four channels 121 of a support pillar 110. There is also a connecting core 140 partially inserted into the center bore 140. Fasteners can be used to fasten each binding connector 150 in place by inserting the fastener through a corresponding through hole 117 on the main body 112 and into a corresponding hole 127 of the connecting core 140.
Once the connecting core 140 and the four binding connectors 150 are fastened in place, another support pillar 110 can be attached thereon as shown in FIG. 4F. Similarly, one may use fasteners to fasten the four binding connectors 150 to the second support pillar 110. The connecting core 140 can be received within a corresponding center bore 114 in the second support pillar 110. In this way, many support pillars 110 can be fixed to one another end-to-end, creating a much longer support pillar 110.
Although four binding connectors 150 and one connecting core 140 are illustrated in FIG. 4F to connect two support pillars 110, the disclosure is not limited to this specific combination. Specifically contemplated methods to connect two support pillars 110 can implement any feasible combinations using any number of the binding connector 150 and any number of the connecting core 140.
As can be understood based on the above description, the binding connector 150 can bind two support pillars 110 together end-to-end. The configuration of the binding connector 150 shown in FIG. 4F can effectively separate one channel 121 from the channel 121 of another support pillar 110. In other words, an item that is slidably engaged within a channel 121 would be stopped from sliding over to the next support pillar 110 because the binding connector 150 is in the way, according to one aspect of the embodiments.
FIGS. 5A-5B show another embodiment of the binding connector 150 where the binding connector 150 can have individual recesses 152, one for each 157 hole. There can be four recesses 152 to respectively receive four fasteners. FIG. 5A shows a top view wherein the binding connector 150 binds two support pillars 110 together end-to-end. FIG. 5B is a cross-sectional side view of what’s shown in FIG. 5A. There is one binding connector 150 on the top side of the support pillar 110 and a binding connector 150 on the bottom side of the support pillar 110. A connecting core 140 is shown in the middle. Here, the four individual recesses 152 are shown for each binding connector 150. Each individual recess 152 is shown to have received a fastener 101.
When two or more support pillars 110 are connected end-to-end, the weakest point is expected to be where one terminal end joins another terminal end. This is particularly true when a bending force is applied to the support pillars 110. For example, the region shown in FIG. 5B can potentially be a weak point when a bending force is applied to the support pillars 110. The presence of channel walls 120 and external lips 122 can alleviate some of the otherwise great deal of stress applied on the fasteners 101 and the threaded holes 117 on the main body 112. In other words, if there were no channel walls 120 and external lips 122, the fasteners 101 would be more likely to pop out of the threaded holes 117. The channel walls 120 and external lips 122 can hold the binding connector 150 firmly in place thereby further minimizing any undesirable deformation.
FIG. 6 is a sectional view taken along line A-A in FIG. 5B and shows four binding connectors 150 each having a shape that snugly fits within a respective channel 121. Fastener 101 connects a binding connector 150 to the connecting core 140, sandwiching the main body 112 of the support pillar 110 in between. The two binding connectors 150 on the left and on the right are shown without their respective fasteners 101 to illustrate how they look without the fasteners 101. Fasteners 101, however, can be inserted through the through holes 157 into corresponding holes in the main body 112 and corresponding holes in the connecting core 140.
In FIG. 6, an exemplary binding connector 150 is shown where there is very little play or tolerance between the binding connector 150 and the channel walls 120 and/or external lips 122. It will, nevertheless, be understood that no limitation of the scope of the disclosure is thereby intended. It is particularly contemplated that in some embodiments, there can be some play or tolerance between a binding connector and its respective channel walls 120 and/or external lips 122. The same goes with FIG. 8E where an exemplary accessories connector 160 is shown where there is very little play or tolerance between an accessories connector 160 and the channel walls 120 and/or external lips 122. In any of the embodiments of this disclosure, there can be contemplated some play or tolerance between the binding connector/accessories connector and the channel walls 120 and/or external lips 122. One example of play or tolerance 165 is shown in FIG. 9E where some play or tolerance 165 is provided between the accessories connector 160 and the external lips 122. This tolerance 165 can be important and can allow for a binding connector 150 and accessories connector 160 to slide within a channel 121 even when the external lips 122 and/or the channel wall 120 is slightly bent in some areas. Among the many different possibilities contemplated, there can have a tolerance 165 of 0.05 to 4.0 mm. It is further contemplated that there can have a tolerance 165 of 0.05 to 2.0 mm. It is further contemplated that there can have a tolerance 165 of 0.10 to 1.0 mm. In other embodiments, it is contemplated that there can have a tolerance 165 of up to 0.5 mm. In yet other embodiments, it is contemplated that there can have a tolerance 165 of 0.01 mm to 10.0 cm. Other sizes of tolerance are also contemplated depending on the size of the channel 121.
Referring now to FIG. 7 showing a prior art aluminum extrusion where an accessory is clamped on. The accessory here is clamped using a screw and a plate. By fastening the screw, the external lips are sandwiched between the accessory and the plate. The inventor has discovered that the attachment of an accessory to this prior art aluminum extrusion is only as strong as the external lips are against bending. In an example, an accessory, such as a large heavy camera that was originally installed onto a prior art aluminum extrusion at a particular angle relative to the aluminum extrusion, can undesirably bent the external lips to which the camera is attached to. Over time, the large heavy camera would no longer be at the originally-intended angle relative to the aluminum extrusion. Also, if the clamping provided by the screw and the plate becomes loose, the camera may slide to a different location along the length of the extrusion.
It is particularly contemplated that in one embodiment, the support pillar 110 can similarly allow an accessory to be clamped onto its lips 122 in the same way as described in FIG. 7.
Alternatively, in the contemplated systems disclosed herein, an accessory can be attached to a support pillar 110 using an accessories connector 160 which will be described below relating to FIGS. 8A-8E, 9A-E, 10A-10D, 11A-11C. In some of these embodiments, the mounting of an accessory can place less mechanical stress on the external lips 122. In some embodiments, the mounting of an accessory can place more mechanical stress on the main body 112 of the support pillar 110. In some other embodiments, the mechanical stress of mounting an accessory can be distributed between the main body 112 of the support pillar 110, the channel wall 120, and the external lips 122.
In FIGS. 8A-8E, an exemplary accessories connector 160 is shown having three holes 167 and eight secondary holes 161. The underside (see FIG. 8C) of the accessories connector 160 shows a countersink 169 provided for each of the three holes 167. The countersink 169 can allow a fastener 101 to flush-mount through the holes 167 as shown in FIG. 8E. In one embodiment, the countersink 169 provides very little tolerance between the head of the fastener 101 and the channel floor 123 (see FIG. 8E). In this way, if the fastener 101 is inadvertently loosen during operation, the fastener 101 can only retract so far. FIG. 8E is a cross-sectional view taken at line B-B of FIG. 8A with the addition of a support pillar 110, a fastener 101, and an accessory 102 in the shape of a plate. This fastener 101 has its shank extending away from the support pillar 110 and can be used to attach (directly or indirectly) to an equipment (e.g., cameras, sensors, signs, lighting equipment, speakers). Referring back to FIGS. 8A-8D, the eight secondary holes 161 can be threaded and they are provided and can each receive a fastener from the top side of the accessories connector 160 and inserted toward the channel floor 123. These eight secondary holes 161 can be offset from the location of the holes 117 of the main body 112. When an appropriately-sized fastener 101 is inserted through a secondary hole 161 and has eventually reached the channel floor, continued fastening can cause the fastener 101 to push the accessories connector 160 towards the lips 122 thereby securing the accessories connector 160 in place. This arrangement can allow the accessories connector 160 to be secured at any location within a channel 121 without the need to correspond to the holes 117 of the main body 112.
This exemplary accessories connector 160 has eight secondary holes 161, while any number of secondary holes are particularly contemplated. Further, these secondary holes can be located anywhere on the accessories connector 160 even at locations where they would correspond with the location of a hole 117 of the main body 112. Also, any size of the secondary hole 161 can be used, including the same size as the size of the hole 167.
In FIG. 8E, the fastener 101 having its shank extending upwards towards an accessory 102 which can be a plate as shown. The plate can have threaded holes to receive the fastener 101. This plate 102 can be fittingly received in the channel of the accessories connector 160. The distance between the two opposing outer lips can be at the same distance as the width of the channel of the accessories connector 160, wherein the plate 102 can be in direct contact with the two opposing outer lips. In this way, the opposing lips can provide additional structural support to improve the integrity of the system. Another accessory can then attach to this plate, in some particular embodiments.
In any of the herein disclosed embodiments, the main body 112 can have a certain thickness of solid mass (whether or not the embodiment has a center bore 114) such that each of the plurality of holes 117 disposed along each channel floor 123 and disposed into the thickness of the main body 112 can have a certain depth (X) to diameter (Y) ratio (see FIG. 8E). In some embodiments, the ratio of depth (X) to diameter (Y) is between and including 0.5:1 and 3:1 but the disclosure is not limited thereto. In some embodiments, the ratio of depth (X) to diameter (Y) is between and including 1:1 and 2:1 but the disclosure is not limited thereto. In some other embodiments, the ratio of depth (X) to diameter (Y) is between and including 1.3:1 and 1.8:1 but the disclosure is not limited thereto. In some other embodiments, the ratio of depth (X) to diameter (Y) is between and including 1.5:1 and 1.7:1 but the disclosure is not limited thereto. In one other embodiment, the ratio of depth (X) to diameter (Y) is 1.25:1, but the disclosure is not limited thereto. In another embodiment, the ratio of depth (X) to diameter (Y) is 1.5:1, but the disclosure is not limited thereto. In still another embodiment, the ratio of depth (X) to diameter (Y) is 1.75:1, but the disclosure is not limited thereto. These contemplated ratios of depth (X) to diameter (Y) can provide sufficient anchoring strength when a fastener 101 is fastened into the hole 117. In another embodiment, the depth (X) can be sufficiently thick to fit thread inserts.
In FIGS. 9A-E, two exemplary accessories connectors 160 are shown received within the same channel 121. FIG. 9C is a close-up view of the exemplary accessories connector 160 shown on the right in FIGS. 9A and 9B, having five holes 157 sized the same and evenly distributed in a consecutive fashion. These five holes 157 correspond with the holes 117 of the main body 112 in size and location. Any of these five holes 157 can receive a fastener 101 in both directions. In other words, although the figures show that only two of the fasteners 101 on the terminal ends are pointed downwards to screw into the main body 112, a user could use the same fastener 101 to screw into the main body 112 using any of the other holes 157. Similarly, although the figures show that only three of the fasteners 101 in the middle are pointed upwards to have their shanks extend away from the main body 112 (to attached to an accessory), a user could use the same fastener 101 using any of the other terminal holes 157 to attach to an accessory. More views of this exemplary accessories connector 160 are shown in FIGS. 10A-10D. Each of these holes 167 can have a countersink 169 on the underside of the accessories connector 160. It should be understood that in one particular embodiment where the holes 167 are threaded, when securing the accessories connector 160 in place within the channel 121. The fastener 101 pointing downwards does not necessarily have to be inserted into a corresponding hole 117 of the main body 112. In such particular embodiments the fastener 101 can push onto the channel floor 123 and can thereby push the accessories connector 160 upward to secure it in place. The embodiment shown in FIG. 9C, however, has five holes 167 that are not threaded. Instead, the holes 117 in the main body 112 are threaded. A fastener 101 can pass through a hole 167 on the accessories connector 160 and screw into the threaded hole 117 of the main body 112. It should also be noted that although FIG. 9C shows the center bore 114 being free of any core connector 140, a core connector 140 can be provided in the center bore 114.
As for FIG. 9D, it is a close-up view of the exemplary accessories connector 160 shown on the left side in FIGS. 9A and 9B. There are three holes 167 in the center portion of the accessories connector 160. These three holes 167 are not threaded in this particular embodiment as shown. Here, a total of four secondary holes 161 are located in the longitudinal midline of the accessories connector 160 thus any appropriately sized fastener 101 placed therethrough can potentially reach a hole 117 in the main body 112. Because such fasteners 101 is smaller than hole 117, they are not expected to securely engage with each other. The secondary holes 161, however, can be spaced apart from each other at a distance different from the distance between each holes 117 of the main body 112. This would allow at least one secondary hole 161 to be offset from the holes 117 of the main body 112. By doing so, at least one fastener 101 that points downward and fastens through the secondary hole 161 can directly abut against the channel floor 123 thereby pushes the accessories connector 160 upward to secure it in the channel 121. For this reason, the secondary holes 161 are threaded. As for any fastener 101 that points downward and fastens through the secondary hole 161 but does not directly abut against the channel floor 123 and is partially inserted into the hole 117 of the main body 112, such fastener 101 may not function to secure the accessories connector 160 in any way.
It is particularly contemplated that any of the holes 117 of the main body 112, any of the holes 157 of the binding connector 150, any of the holes 167 of the accessory connector 160, any of the holes on the connecting core 140, and any of the holes 177 of the end pieces can or cannot have threads. When any combination of the above parts is used in a system, it is particularly understood that any threaded and unthreaded combination is possible. For example, in an embodiment similar to what’s shown in FIG. 9C, the fastener 101 on the far left may have a double threaded combination where the hole 167 of the accessories connector 160 and the hole 117 of the main body 112 are both threaded. Alternatively, as shown in FIG. 9C, only the hole 167 of the accessories connector 160 is threaded and the hole 117 of the main body 112 is not threaded. In another embodiment, the hole 167 of the accessories connector 160 is not threaded and the hole 117 of the main body 112 is threaded.
In FIGS. 11A-11C, another exemplary accessories connector 160 is shown to have holes 167 each with a countersink 169 and secondary holes 161. FIG. 11C shows the shank of two fasteners 101 to extend upward and away from the main body 112 of the support pillar 110. Smaller fasteners 101 could be inserted downward from the upside of the accessories connector 160 through secondary holes 161 and abutted against the channel floor 123 (not shown). The secondary holes 161 can be threaded, and these smaller fasteners 101 can in effect push the accessories connectors 160 upwards as similarly described for the accessories connector 160 of FIG. 9D.
There can be provided optional end pieces 170 in the contemplated modular framing system. FIGS. 12A-12C show two types of end piece 170. FIG. 12A shows an end piece 170 to have a head portion 172 and a core insert 174 attached thereto. FIG. 12B is similar except it has an additional core insert 174 disposed on the opposite end of the head portion 172. An end piece 170 is contemplated to have holes 177 disposed on the head portion 172 or the core insert 174, or both. The size and location of the holes 177 preferably correspond with the size and location of the holes 117 of the main body 112. FIG. 12C shows an end piece 170 coupled to a support pillar 110 and secured in place by four binding connectors 150. The exterior surface of the head portion 172 can correspond with the surface of the channel floor 123 such that the exterior surface of the head portion 172 is flush with the surface of the channel floor 123. On the exposed face 171 of the end piece there can be a mounting hole 179. The mounting hole 179 can be threaded to attach to an accessory.
The end piece 170 of FIG. 12B, on the other hand, can couple to two support pillars 110 on each end thereby connecting the two support pillars together. In this situation, four longer binding connectors 150 (not shown) can be used to bind the end piece 170 to the two support pillars 110.
FIGS. 13A, 13B, 14A, 14B, and 15 illustrate the various uses of the above described parts in various applications. In FIGS. 13A, 13B, 14A, 14B, support pillars 110 can be coupled together in parallel by using an accessory 102 (i.e., angled plates) thereby creating a reinforced truss. In FIG. 15 the system can be used to create a structure for a display board or promotional screen.
