Definitions
- the present invention is directed to connecting apparatus between structural members, such as structural tubes, trusses, space frame nodes and other such structural assemblies.
- a truss is understood to comprise a plurality of parallel tubes, bars, rods or other straight members held spaced apart at various points along the length of each of the members in order to form a stronger structural member than each member would be individually.
- the trusses have lengths which are usually shorter than a span across which they are to extend. Consequently, it is necessary to connect trusses end to end and, also, to connect end trusses to structural walls or other such items.
- the almost universal mechanism for making such a connection is to bolt one truss to another or to bolt the truss to a structural wall. Nut and bolt connections are positive, and structural adequacy is easily verified. The disadvantage with nut and bolt connections is that they are time consuming to accomplish and, consequently, expen ⁇ sive.
- a space frame commonly includes a plurality of nodes and tubes in various arrangements depending on the application.
- Space frames are used to support roofs, walk ⁇ ways, scaffolding, and often provide modern looking struc ⁇ tural support in architecturally pleasant buildings such as halls, churches, office buildings, etc.
- a space frame is constructed by a single tube extending bet ⁇ ween a pair of nodes.
- Each node has a plurality of faces and can receive a tube at each face. Therefore, it is com ⁇ mon for a number of tubes to be attached to a single node so that a complex, but usually uniform, pattern is formed.
- U. S. Patent 2,149,844 shows a sleeve device into which one or more tubes may be inserted and welded.
- U. S. Patent 4,343,562 shows a somewhat different structure but also utilizes the concept of inserting a tubular member into a core member and welding the two.
- Other patents show different concepts.
- U. S. Patent 3,914,060 shows a node member having a plurality of studs with sleeves attached thereto for threading onto ends of tubular sections.
- U. S. Patent 4,023,913 shows a connector having socket-like ends over which tubular members fit.
- Patent 4,313,687 shows a node having a plurality of threaded openings, each of which are for receiving a bolt retained to an end of a tube. A pair of threaded bodies attached to the bolt function to tighten the tube to the node.
- Other commercial systems are available which, actually have a threaded rod fixed at the end of a tube for threading into a threaded opening in a node.
- a node connection includes a plura ⁇ lity of half joints having semicircular tongue and groove elements with tubes having similar tongue and groove ele ⁇ ments mating therewith. Locking latches are provided to keep the halves from separating.
- the present invention is directed to interconnect mechanism between first and second structural members.
- the mechanism includes a button fastened to the first structural member.
- the mechanism further includes a receiver for the button formed as an arcuately shaped cradle having a wall on one side and a lip on an opposing side.
- the receiver is fastened at the wall to the second structural member. In this way, receipt of the button within the cradle simply yet sufficiently interconnects the two structural members together.
- the button is generally in the form of a solid cylinder with an axial opening for allowing the shaft of a bolt to pass through.
- a cavity at one end of the button receives the head of the bolt.
- the structural tube preferably includes a solid rod plug at its end. The bolt is then threaded into the plug to fasten the button to the tube.
- the receiver is also a cylindrical block, but has a cavity extending inwardly from the cylindrical wall.
- the cavity has a semi-cylindrical end coaxial with the axis of the block.
- a slot in one end of the block extending to the cavity is necessary for receiving the solid rod to which the button is fastened when the button is received by the cradle formed by the semi-cylindrical cavity.
- the solid end wall of the receiver has an axial passage for a bolt to pass therethrough with a cavity for the head of the bolt. As with the button, the receiver is fastened with the bolt to a solid rod welded or otherwise attached in the end of the second structural tube.
- the dimensions of the button match relatively closely the dimensions of the cavity so that the button, although loose, is snugly received in the cradle.
- Such connection is then not only quite solid, but provides structural strength which is predictable and can be used advantageously for design purposes.
- a further feature of the present connector includes a keeping or locking mechanism for preventing the button from sliding from the cradle.
- a simple such mechanism inclu ⁇ des a clip having one leg inserted in an opening in the receiver wall adjacent to the top of the button with another leg frictionally retained at the top of the receiver wall.
- Such feature is simple, rapid to assemble, and advan ⁇ tageously alleviates any concern of the button bouncing from the cradle under circumstances which might otherwise cause such disconnection.
- the interconnection mechanism of the present inven ⁇ tion is advantageously applicable for connecting a pair of truss members together.
- a button is attached to each tube or elongated member of a first truss, while receivers are attached to each elongated member of a second truss.
- the buttons are simultaneously placed in the cradles of the receivers and the keepers installed.
- the connection is simple, quick, inexpensive to make and assemble, yet relati ⁇ vely solid and positive. -"
- an alter ⁇ native is to rotate one or more receivers after the button or buttons have been received.
- a spring bias plunger or some other means of preventing rotation is used in this embodiment to hold the rotated receiver from inadvertently rotating further.
- the receiver is advantageously knurled so that it may be readily grasped and turned preferably by hand.
- the plunger preferably includes a cammed device or other similar device for retracting the plunger from the cavity into which it falls to prevent further rotation. The cam and the knurled wall on the receiver alleviate the need for extraneous tools while connecting the truss members together or disconnecting them.
- the present connecting apparatus is further advan ⁇ tageous for use in creating space frame structures.
- a node may be formed to include a plurality of faces with receivers fastened to one or more of the faces. Tubes may then be connected thereto in the usual fashion by placing a button in a cradle and locking it in place.
- the creation of a space frame using the present connecting mechanism is simple and quick, yet strong and positive.
- the present connecting mechanism is a signi- ficant improvement over known connectors, not only because of the simple design and consequent inexpensive manufacture, ' but also because of the ease of assembly, yet strength of connection and capability of preventing disconnection.

- FIGURE 9 shows both a side elevation and an end elevation of first and second truss members coming together for connection;
- FIGURE 10 shows an end elevational view of two con ⁇ nected truss members with one of the truss members in cross section.
- interconnecting apparatus in accordance with the present invention is designated generally by the numeral 10.
- Apparatus 10 includes a button 12 attached to a solid rod 14 fastened within tube 16.
- Button 12 is contained within receiver 18 fastened to rod 20 which is fixed to tube 22.
- Retainer 24 clip prevents button 12 from undesirably sliding out of receiver 18.
- button 12 is a cylindrical block having a pair of ends 26, 28.
- Button 12 is provided with an axial passage 30 in com ⁇ bination with an axial cavity 32 in end 26 for receiving the shank and head of screw or bolt 34, respectively.
- Cavity 32 is sufficiently sized to receive the head of screw 34 so that it does not extend beyond end 26.
- Button 12 has suf ⁇ ficient thickness and diameter to retain necessary strength in spite of cavity 32 and passage 30.
- Rod 14 is a plug of several inches in length and is inserted in the end of tube 16 and attached with a plurality of randomly located spot welds 36. Preferably, rod 14 extends a short distance from the end of tube 16 so that tube 16 does not interfere with receiver 18 when button 12 is placed in receiver 18. Rod 14 provides for and strengthens the end of tube 16 for the attachment of button 12 with screw 34.
- Receiver 18 is formed to include a cradle 38 with a wall 40 on one side and a lip 42 on the other. Receiver 18 is preferably a cylindrical block with ends 44, 46. End 44 may be trimmed at the corner to eliminate unnecessary mass. A sufficient flat surface, however, must be retained to butt against rod 20.
- Cradle 38 is formed to include a cavity extending inwardly from the cylindrical wall and ending in a semi-cylindrical curvature coaxial with the axis of the block. Lip 42 results when a slot centered on the cavity of cradle 38 is formed. The slot end is semi-cylindrical, and coaxial with the axis of the block. " The slot between the sides of lip 42 has width sufficient to allow rod 14 to pass therethrough.
- Button 12 has a diameter greater than the diameter of rod 14 so that lip 42 retains button 12 from sliding axially from cradle 38.
- the width and cylindrical diameter of the cavity of cradle 38 is slightly greater than the diameter of button 12 to allow button 12 to be easily received by cradle 38, while yet maintaining a relatively snug abutment.
- End 46 is preferably rounded with the inner portion collapsing toward lip 42 so as to leave only a rela ⁇ tively short thickness for lip 42. In this way, end 46 and lip 42 do not interfere with tube 16 as rod 14 passes through the slot formed by lip 42.
- An axial passage 48 extends through rear wall 40. Additionally, a cavity 50 is coaxial with the axis of receiver 18. As with passage 30 and cavity 32 of button 12, passage 48 and cavity 50 of receiver 18 are sized to receive screw 52. As with button 12, the thickness and diameter of receiver 18 are sufficient to provide the strength charac ⁇ teristics for a particular application. As indicated hereinbefore, end 44 of receiver 18 butts against rod 20 and is fastened thereto with screw 52. Rod 20 is a plug of several inches in length and is attached to tube 22 with a plurality of random spot welds 36 through openings in tube 22. As with rod 14, rod 20 provides for and strengthens the end of tube 22 for the attachment of receiver 18 with screw 52.
- a locking mechanism such as clip 24, is located to hold button 12 snugly in cradle 38.
- a number of equivalent locking mechanisms are possible, but a simple embodiment is shown to include a passage 54 in wall 40 at the top of but ⁇ ton 12.
- Clip 24 has a lower leg 56 which passes through passage 54, and an upper leg 58 which retains clip 24 to the upper edge of wall 40.
- Connector 10 may be used to interconnect a pair of tubes 16, 22, as shown in FIGURE 2. Also, a plurality of connectors 10 may be used in a similar fashion to connect a pair of trusses together as shown in FIGURES 5 and 6. Trusses 60, 62 in FIGURE 5 each have three tubes 16', 22'. Various webbing rods are welded or otherwise attached to hold the tubes in a fixed, spaced-apart structural rela ⁇ tionship. A button 12" is attached to the end of each tube 16' at a rod 14' in the fashion described hereinbefore. Similarly, a receiver 18' is attached to the end of each tube 22' at a rod 20'. With such configuration, truss 62 is connected to truss 60 by simply sliding all of buttons 12' into receivers 18' simultaneously. Appropriate lock mecha ⁇ nisms prevent the trusses from inadvertently separating.
- Trusses 66, 68 in FIGURE 6 are connected together in a similar fashion. Trusses 66, 68 each have four tubes 16' ' , 22' ' connected together with webbing 64* ' . Buttons 12' ' and receivers 18'' are attached in the fashion described hereinbefore. All of buttons 12' ' are received simultaneously by receivers 18 8 I to hold truss 66 to truss 68. A locking mechanism for each of connectors 10'* pre ⁇ vents inadvertent disconnection.
- interconnect mechanism 10 may also be used in a space frame structure designated herein as 70.
- Space frame 70 includes nodes 72, 74.
- a plurality of tubes 76 extend between nodes 72, 74 and other nodes (not shown) or other structural members (not shown).
- Each node, for example 72 has a plurality of faces 78. Centered in each face is a threaded passage 80.
- a receiver 18* ' ' is attached to the various faces 78 which are needed for use as attachments.
- Receivers 18' ' ' are attached with a screw 52''' in the same fashion as screw 52 attaches a receiver 18 to a rod 20.
- Tubes 76 have buttons 12' ' ' attached at both ends in order to be received at each node.
- nodes and tubes may be used to create a variety of designs in the usual fashion of space frames and, consequently, may be used in any of the various applications appropriate for space frames.
- the present invention is particularly advantageous for space frame creation since it is so rapidly assembled and disassembled, while yet maintaining structural integrity and strength.
- buttons and receivers are preattached to rods, tubes, trusses or similar struc ⁇ tural members.
- assemblers simply insert the buttons into the receivers so the buttons rest in the cradles of the receivers and are retained between the lips and end walls of the cradles.
- the buttons are locked in place using, for example, a clip 24 or some other locking mechanism.
- receivers 18''' are attached to appropriate faces 78 of nodes. Tubes 76 with buttons 12' ' ' at both ends are extended between a pair of nodes and slipped in the receivers and locked in the same fashion as hereinbefore indicated.
- FIGURES 7-10 show an alternate embodiment of the connecting apparatus of the present invention which pro ⁇ vides for rotation of the receiver with respect to the member to which it is attached.
- connector apparatus 10*''' is shown with a button 12' ' ' ' attached to a plug 14' ⁇ ' » in the end of a tubular member 16' 1 '' with a bolt 34''''.
- button 12' 1 ' 1 is shown to have a neck portion 90 having a smaller diameter than the diameter of the outer portion 92 which is received in receiver 18*'''.
- plug 14'''' ' extends somewhat beyond the end of tubular member 16'''' with the extended portion 94 having a diameter approximately equal to the outer diameter of tubular member 16''''.
- Receiver 18'''' is fastened to plug 20*''* with bolt 52'"'.
- Plug 20"' ' is formed similar to plug 14" rt to have an extending portion 96 with a diameter approxi- matley the same as the outer diameter of tubular member 22 ,l , f .
- Plug 20'' 1 ' is welded or otherwise attached to tubular member 22' ' ' ' as is plug 14'''' to tubular member 16' ' ' ' .
- Receiver 18*' ' ' is formed to include a cradle 38'''' in the fashion of cradle 38 described hereinabove.
- the back wall 40' 1 '' includes a cavity 50 , , r r and an axial passage 48' ' ' ' for receiving the head 98 and shank 100 of bolt 52''''.
- a metallic bushing 102 is located between head 98 and the back wall 104 of the cavity which receives head 98.
- Another metallic bushing 106 is located between the facing surfaces of receiver 18' ' f ' and plug 20' ' ' ' . The metallic bushings 102 and 106 allow receiver 18'''' to be rotated without loosening bolt 52' ' ' ' .
- bolt 52' ' ' * is preferably held in place with an appropriate adhe ⁇ sive material between its threads and the threads of plug 20'' '' or with other known locking mechanism.
- a first 0— ring seal 108 may be formed in the facing surface of either plug 20' , , r or receiver 18' 11 '.
- a second 0-ring seal 110 may be formed in either the wall surface of cavity 50'' '' or in the surface of head 98. Seals 108 and 110 enclose a space which includes bushings 102 and 106 so that a lubri ⁇ cant grease may be used in the space to make rotation of receiver 18'''' easier.
- the preventing mechanism 112 includes a plunger 114 located along the centerline of cradle 38'' '' " in the outer wall 118 of receiver 18'''' in the space bet ⁇ ween cavity 38'''' and plug 20' ' ' ' ..
- a passage 116 is formed in outer wall 118 having a smaller diameter near the outer wall 118 and a larger diameter portion 120 near the cavity 50'' '' for head 98 of bolt 52' ' ' ' .
- Plunger 114 is formed to have larger diamter knobs 120 and 122 with a neck 124 there ⁇ between.
- a coil spring 126 is located between wall 128 at the end of the larger diameter passage 118 and knob 122 of plunger 114 which is fitted in portion 118. Thus, plunger 114 is biased so that knob 122 is forced against head 98 of bolt 52" " .
- Head 98 includes at least one cavity 130 in its cylindrical surface for receiving knob 122 of plunger 114 and thereby preventing further rotation of receiver 18"" with respect to structural member 22"". It is often desirable to include a plurality of equally spaced cavities 130 about head 98.
- the present interconnecting apparatus may be used without the necessity of other tools to aid in connecting one structural member to another.
- Cam 134 has an arcuate por ⁇ tion 136 near wall 118 and a straight portion 138 extending away therefrom.
- Cam 134 is pivotally attached to knob 120 of plunger 114 at pivot pin 140.
- straight portion 138 of cam 134 forms a slight incline with wall 118.
- straight portion 138 is pivoted about pin 140 to force arcuate portion 136 against wall 118 and move plunger 114 radially outwardly.
- first and second trusses 60"" and 62"" In use, and in reference to connecting first and second trusses 60"" and 62"" together, reference is made to FIGURES 9 and 10. All receivers attached to first truss 60"" are oriented so that the cradles open in the same direction and the centerlines of the cradles are generally parallel to one another. In this fashion, the buttons 12"" of second truss 62"" are easily slipped into all cradles simultaneously. Trusses 60"" and 62"” are locked together by rotating each receiver until further rotation is prevented by a functioning of plunger 114.
- each receiver is rotated so that the cradles open outwardly from the centerline of truss 60"" and the centerlines of the various cradles come close to inter ⁇ secting near the centerline of truss 60"". It is understood, of course, that exactness is not required with respect to the intersection of the various cradle cen ⁇ terlines, but the closer such intersection comes to the cen ⁇ terline of truss 60"", the more unlikely an inadvertent rotation of one or more of receivers 18"” would occur and an inadvertent disconnection take place.
