专利摘要:
COUPLING THAT HAS ARCHED RIGID CHANNELS. It is a coupling for joining end-to-end tube elements that has a unitary strip that surrounds a central space to receive the tube elements. The ends of the strip are facing each other. The adjustable connecting members are positioned at each end of the strip to move the ends towards each other and deform the strip. Arched channels are positioned lengthwise along opposite sides of the strip. The channels are separated from each other by gaps between the channels. In their undeformed state, each channel has an arcuate surface with a radius of curvature equal to the radius of curvature of the outer surface of the pipe elements that they engage. When the strip is deformed, the channels embrace the outer surface of the tube elements to effect the joint.

CROSS REFERENCE TO RELATED ORDERS
[001] This order is based on and claims priority for US Provisional Order No. 61 / 818,686, filed on May 2, 2013, and US Provisional Order No. 14 / 263,350, filed on April 28, 2014, both of which are incorporated by reference. FIELD OF THE INVENTION
[002] This invention relates to couplings for joining tube elements in relation from end to end. BACKGROUND
[003] The “Straub” type couplings are formed of a unitary strip that has free ends that are subjected to the tangential tension force to fix the strip around the tube elements to be joined end to end. By means of tensioning force, the strip deforms radially inwards to cover a smaller diameter and forces the toothed retaining rings captured between the strip and the tube elements in engagement with the tube elements. Deformation of the strip also compresses a seal against the pipe elements to ensure a fluid-tight joint. Examples of Straub type couplings are disclosed in US Patent Nos. 4,629,217, 4,664,422, 5,137,305 and 5,280,970.
[004] Joints formed by Straub type couplings are often flexible in bending. Although bending flexibility is sometimes desired in piping networks, for situations where more bending rigidity is required, Straub-type couplings are inappropriate. There is clearly a need for a coupling that combines the advantages of the Straub type coupling with the increased bending stiffness normally associated with other types of mechanical couplings. SUMMARY
[005] This invention relates to a coupling to join tube elements in relation from end to end. In an exemplary embodiment, the coupling comprises a unitary strip that surrounds a central space to receive the tube elements. The strip has first and second ends positioned facing each other. A plurality of arcuate channels are positioned end to end along opposite sides of the strip. Each of the channels protrudes towards a geometric axis coaxial with the central space. Each channel has a surface facing the geometric axis. The surface in each of the channels has a radius of curvature equal to the radius of curvature of an external surface of the tube elements when the channels are in an undeformed state. The connecting members are positioned at the first and second ends of the strip. The connecting members are tightened tightly to move the first and second ends towards each other. The strip is deformable between each channel. This allows the first and second ends to move towards each other by means of the adjustable tightening of the connecting members. The surfaces in each of the channels are thus brought into engagement with the outer surfaces of the tube elements.
[006] In a particular exemplary embodiment, the coupling also comprises a seal positioned within the central space between the arched channels. The seal surrounds the geometrical axis and is interlockable with the strip and the tube elements to seal the end-to-end tube elements sealingly.
[007] As an example, connection members may comprise a pair of projections. A projection is positioned at each of the first and second ends of the strip. The projections extend outward and are adapted to receive a fastener. The fastener is tightened snugly to move the first and second ends towards each other. In a specific exemplary modality, the projections comprise protrusions. Each protuberance has an opening through it sized to receive the fastener.
[008] In another exemplary embodiment, the coupling also comprises a first division ring positioned within the central space. The first split ring is positioned adjacent to the arcuate channels along a first between the sides of the strip. The first split ring has a plurality of teeth that protrude towards the geometric axis. The teeth engage with the outer surface of the tube element. In another exemplary embodiment, the coupling may further comprise a second split ring positioned within the central space adjacent to the arcuate channels. The second split ring is positioned over a second between the sides of the strip. The second split ring has a plurality of teeth that protrude towards the geometric axis. The teeth of the second split ring engage with the outer surface of the tube element.
[009] In another exemplary embodiment, the coupling comprises a first plurality of grooves. Each groove extends in the direction of the length along a respective one of the channels positioned along a first side of the strip. Each of the grooves faces the geometric axis. A first split ring is positioned within the first plurality of grooves. The first split ring has a plurality of teeth that protrude towards the geometric axis. The teeth engage with the outer surface of the tube element. The exemplary embodiment can also comprise a second plurality of grooves. Each groove of the second plurality extends in the direction of the length along a respective one of the channels positioned along a second side of the strip. Each groove of the second plurality faces the geometric axis. A second split ring is positioned within the second plurality of grooves. The second split ring has a plurality of teeth that protrude towards the geometric axis. The teeth of the second split ring engage with the outer surface of the tube element.
[010] The exemplary embodiments of the couplings according to the invention can be adapted to join tube elements which include smooth end tube elements, circumferentially grooved tube elements, and shoulder end tube elements.
[011] In a particular embodiment of a coupling according to the invention, the surfaces in the channels engage with the external surfaces of said tube elements when the connecting members are in contact with one another. In a further example, the channels are separated from each other by gaps positioned between each of the channels.
[012] The invention also encompasses the combination of a pair of tube elements and a coupling to join the tube elements in relation from end to end. In an exemplary embodiment, each of the tube elements comprises an outer surface that has a radius of curvature. As an example, the coupling comprises a unitary strip that surrounds a central space for receiving the tube elements. The strip has first and second ends positioned facing each other. A plurality of arcuate channels are positioned end to end along opposite sides of the strip. Each of the channels protrudes towards a geometric axis coaxial with the central space. Each channel has a surface facing the geometric axis. The surface in each of the channels has a radius of curvature equal to the radius of curvature of the outer surface of the tube elements when the channels are in an undeformed state.
[013] The example also includes connecting members positioned at the first and second ends of the strip. The connecting members are tightened tightly to move the first and second ends towards each other. The strip is deformable between each of the channels, which allows the first and second ends to move towards each other by means of the adjustable tightening of the connecting members. The surfaces in each of the channels are thus brought into engagement with the outer surfaces of the tube elements.
[014] In an exemplary combination, the tube elements are selected from the group consisting of smooth end tube elements, circumferentially grooved tube elements, and shoulder end tube elements.
[015] In an additional mode, the channels are separated from each other by gaps positioned between each of the channels.
[016] This invention also contemplates a method of joining tube elements in relation from end to end. In an exemplary embodiment, the method comprises: inserting the tube elements in a central space defined by a non-deformed unitary strip that has first and second ends facing each other and a plurality of arched channels positioned end to end along opposite sides of the strip, each of the channels having a surface with a radius of curvature equal to a radius of curvature of an external surface of the tube elements; displacing the first and second ends towards each other, thereby deforming the strip in a plurality of points between the plurality of channels in order to engage the surfaces of the channels with the outer surfaces of the tube elements.
[017] The example method may further comprise compressing a split ring positioned within the central space and adjacent to the channels along one side of the strip, the split ring has a plurality of teeth, the teeth are forced to engage with one of the tube elements by compressing the split ring.

[026] Figure 1 shows an exemplary coupling 10 according to the invention. The coupling 10 comprises a unitary strip 12 that extends circumferentially to surround and define a central space 14. The strip 12 is dimensioned so that the central space 14 can receive the inserted tube elements axially (see Figures 3 to 5) to be joined end to end. The tube elements are inserted axially into the central space 14 from the opposite sides of the coupling 10. The strip 12 has first and second opposite ends 16 and 18 which are positioned facing each other. The connecting members, in this example, projecting out of the protrusions 20 and 22, are positioned respectively at the first and second ends 16 and 18 of the strip 12. Each protrusion 20, 22 has an opening 24 adapted to receive an tightly tightened fastener , in this example a screw 26 and a cylindrical nut 28. The tightening of the screw and the cylindrical nut moves the first and second ends 16 and 18 towards each other to fix the coupling 10 to the tubes that are joined as described in detail below. It is noted that the cylindrical surface of the cylindrical nut 28 facilitates the relative rotation of the protuberance 22, which thereby decreases the torque required to displace the ends 16 and 18.
[027] A plurality of arcuate channels 30 are positioned end to end along opposite sides 32 and 34 of strip 12. Each channel 30 projects towards a geometric axis 36 positioned coaxially with the central space 14. Each channel 30 has a surface 38 that faces the geometric axis 36. In the exemplary embodiment disclosed in this document, surfaces 38 are shown as flat surfaces, however, it is understood that the term "surface" as used with reference to channels 30 encompasses other formats such as concave, convex as well as knife-edge shapes. When each channel is in a non-deformed state, each surface 38 has a radius of curvature 40, equal to the radius of curvature of the outer surface of the tube element which is engaged when forming the joint. Couplings 10, which have surfaces 38 with a radius of curvature 40, equal to the outer surface of the tube element when the channels 30 are in a non-deformed state, are different from Straub couplings of the prior art, in which the surfaces turned inwards, in their undeformed state, have a greater radius of curvature than the tube elements to allow axial insertion of the tube elements into the coupling. In coupling 10, channels 30 do not deform significantly. The deformation in the coupling 10 is substantially confined to the regions of the band 12 between the channels 30 through the presence of gaps 42 positioned between each channel 30. The gaps 42 isolate the channels from each other, thereby allowing channels 30 to act independently each other and the strip when the strip deforms radially by tightening the screw 26.
[028] When used to join the flat end tube elements, the coupling 10 includes retainers 44. The retainers are positioned on opposite sides 32 and 34 of the strip 12 within the central space 14 and adjacent to the channels 30. The retainers 44 comprise a split ring 46 having a plurality of teeth 48 projecting towards the geometric axis 36. The retainers 44 are advantageously formed of spring steel. In a particular exemplary embodiment, the teeth can be dimensioned to hold and retain the tube elements by inserting them in the central space. The holding and retaining action of the retainers 44 greatly facilitates the assembly of the joint, since it is not necessary to independently hold any element between the tube element and the coupling 10 in place while manipulating tools, or other tube elements and the like during assembly. In the illustrated embodiment, teeth 48 are oriented angled towards the opposite side from the side on which they are mounted (see also Figure 2). The angularly oriented teeth 48 are self-acting and greatly inhibit the extraction of a tube element once inserted in the central space 14.
[029] As shown in Figure 2, it is advantageous to position the split rings 46 within the grooves 50. The grooves 50 are positioned on the opposite sides 32 and 34 of the strip 12. The grooves 50 face the geometric axis 36 and extend in the direction of the length along each channel 30, in effect, divide the channels in the direction of the length. The formation of grooves 50 within channels 30 provides several advantages. The split channels support the split rings 46 and prevent them from moving axially when subjected to the load. Grooves 50 also increase the width of the projection area of the channels in the tube elements while maintaining the weight of the coupling. The increased projection area additionally increases the stiffness of the joint formed with the coupling 10 as described below.
[030] To ensure a fluid-tight joint, a seal 52 is positioned within the central space 14 between channels 30. In this exemplary embodiment, seal 52 is a ring gasket formed of a flexible material such as a rubber compound . The seal 52 has lips 54 that sealably engage the external surfaces of the tube elements when they are inserted in the coupling 10 (see Figure 5). The seal also comprises a central lock 56 that protrudes inwardly towards the geometry axis 36. The lock 56 engages with the ends of the tube elements inserted in the coupling 10 to ensure that the tube elements engage with the coupling for depth (see Figures 3 and 4). The seal 52 is compressed between the strip 12 and the tube elements by tightening the screw 26 to affect a fluid-tight joint (see Figure 5).
[031] As shown in Figures 3 and 4, the tube elements 58 and 60 are joined using coupling 10, first inserting each tube element axially from the opposite sides 32 and 34 in the central space 14 defined by track 12. Track 12 is in its undeformed state during insertion; that is, the screw 26 is not yet tightened and the ends 16 and 18 are spaced apart from each other (see also Figure 6). By inserting the tube elements 58 and 60, the respective outer surfaces 58a and 60a of the tube elements can be engaged by the teeth 48 of the split rings 46. The teeth 48 can be designed to hold enough to retain the coupling 10 in a tube element against its own weight, as well as against minor forces exerted when handling the various components of the joint. The outer surfaces 58a and 60a of the tube elements 58 and 60 also engage with the lips 54 of the seal 52, and the respective ends 58b and 60b of each tube element 58 and 60 engage with the lock 56 to ensure engagement depth between the tube elements and the coupling 10.
[032] A view of the coupling 10 in the non-deformed state that receives the tube element 58 is provided in Figure 6. Note that the gaps 42 between channels 30 and the spaced relationship between ends 16 and 18 of track 12 in that view.
[033] As shown in Figures 5 and 7, the screw 26 is thus tightened, which cooperates with the cylindrical nut 28 to move the protuberances 20 and 22 towards each other and with them, at the ends 16 and 18 of band 12. Band 12 deforms primarily at the locations of the gaps 42 between channels 30 where the folding stiffness of the band is minimal. Strip 12 will deform progressively, and folds first at gap locations 42 circumferentially from the ends 16 and 18 where the applied moment is greatest, and finally at the gap locations closest to the ends. As band 12 deforms, the surfaces of channel 38 are brought into engagement with the outer surfaces 58a and 60a of tube elements 58 and 60. This engagement between channels 30 and tube elements 58 and 60 provides significant bending stiffness for the joint, otherwise absent in similar couplings. The fact that the channels 30 themselves do not deform significantly is not a consequence since the radii of curvature 40 of the channel surfaces 38 and their undeformed state are equal to the radii of curvature 58c, 60c of the outer surfaces 58a, 60a of the tube elements 58, 60 with which they engage. The wide projection area provided by dividing the channels 30 with the groove 50 further increases the stiffness of the joint bend by providing spaced surfaces 38 that support the tube elements over a greater distance. It is advantageous to have portions of the connecting members (protrusions 20 and 22) and / or the ends 16 and 18 in contact with each other in what is known as a “block-to-block” relationship when the surfaces of the channel 38 are engaged with the outer surfaces of the tube elements. In this example, block-to-block contact is made when ends 16 and 18 meet, as shown in Figure 7. Block-to-block contact is advantageous since it provides visual confirmation that the coupling is properly installed and avoids the need for specify screw torques for proper installation. Note also the reduction in the size of gaps 42 in Figure 7 as compared to Figure 6.
[034] As band 12 deforms, it compresses division rings 46, which, being division rings, deform radially in a smaller diameter. As the split rings 46 deform, the teeth 48 further dig into the surface of the tube elements and provide increased resistance to axial forces that tend to separate the tube elements from the coupling. Strip 12 also compresses seal 52 against tube elements 58 and 60 to ensure a fluid-tight joint. It is noted in Figure 5 the engagement of lips 54 with the external surfaces of the tube element 58a and 60a when the seal 52 is compressed.
[035] Figure 8 shows a coupling 62 for use with tube elements that have circumferential grooves. Coupling 62 comprises a unitary strip 64 that extends circumferentially to surround and defines a central space 66. The strip 64 is dimensioned so that the central space 66 can axially receive the inserted tube elements (see Figures 9 to 11) to be joined end to end. The tube elements are inserted axially into the central space 66 from the opposite sides of the coupling 62. The strip 64 has first and second opposite ends 68 and 70 which are positioned facing each other.
[036] The connecting members, in this example, which project protrusions 72 and 74 outward, are positioned respectively at the first and second ends 68 and 70 of track 64. Each protrusion 72, 74 has an opening 76 adapted to receive a fastener tightly tightened, for example, a bolt 78 and a cylindrical nut 80. Adjusting the bolt and cylindrical nut moves the first and second ends 68 and 70 towards each other to secure coupling 62 to the tubes that are joined as described in detail below.
[037] A plurality of arcuate channels 82 are positioned end to end along opposite sides 84 and 86 of lane 64. Each channel 82 projects towards a geometric axis 88 positioned coaxially with central space 66. Each channel 82 has a surface 90 that faces the geometric axis 88. In the exemplary embodiment disclosed in this document, surfaces 90 are shown as flat surfaces, however, it is understood that the term "surface" as used with reference to channels 82 encompasses other formats such as concave, convex as well as knife-edge shapes. When each channel is in a non-deformed state, each surface 90 has a radius of curvature 92, equal to the radius of curvature of the outer surface of the tube element within the circumferential groove that is engaged when forming the joint. In coupling 62, channels 82 do not deform significantly. The deformation in coupling 62 is mainly confined to the regions of strip 64 between channels 82 through the presence of gaps 94 positioned between each channel 82. Gaps 94 isolate the channels from each other, thereby allowing channels 82 to act independently of each other and the strip 64 when the strip deforms radially by tightening the screw connecting the ends 68 and 70 towards each other. Similar to coupling 10 shown in Figure 1, coupling 62 will also have a seal (not shown for clarity, see Figures 9 to 11) within central space 66 and between channels 82.
[038] As shown in Figures 9 and 10, the circumferentially grooved tube elements 96 and 98 are joined first by inserting each tube element axially from opposite sides 84 and 86 of track 64 in the central space 66 defined by track 64 Track 64 is in its undeformed state during insertion; that is, the screw 78 for adjusting the coupling is not yet tightened (see also Figure 12). Upon insertion, the respective outer surfaces 96a and 98a of the tube elements 96 and 98 will engage the lips 54 of the seal 52 within the central space 66, and the respective ends 96b, 98b of each tube element 96 and 98 will also engage with a lock 56 on the seal 52 to ensure proper engagement depth between the pipe elements 96 and 98 and the coupling 62. A view of the coupling 62 in the non-deformed state that receives the pipe element 96 is provided in Figure 12. Note - it appears that the gaps 94 between channels 82 and the spaced relationship between the ends 68 and 70 of track 64 in this view.
[039] As shown in Figures 11 and 13, when the screw 78 is tightened, it cooperates with the cylindrical nut 80 to move the protrusions 72 and 74 towards each other and with them, at the ends 68 and 70 of the strip 64. Strip 64 deforms primarily at the locations of the gaps 94 between channels 82 where the folding stiffness of the strip is minimal. Strip 64 will deform progressively, and folds first at gap locations 94 circumferentially from the ends 68 and 70 where the applied moment is greatest, and finally at the gap locations closest to the ends. As the strip 64 deforms, the surfaces of the channel 90 are brought into engagement with the outer surfaces 96a, 98a of the tube elements 96 and 98 within the respective circumferential grooves 96c and 98c. The fact that the channels 82 themselves do not deform significantly is not of consequence since the radii of curvature 92 of the channel 90 surfaces and their undeformed state are equal to the radii of curvature 96d, 98d of the outer surfaces 96a, 98a of the tube elements 96 and 96 with which they engage. It is advantageous to have portions of the connecting members (protrusions 72 and 74) and / or the ends 68 and 70 in contact with each other in what is known as a “block-to-block” relationship when channel 90 surfaces are engaged with the outer surfaces 96a, 98a of the tube elements 96 and 98 within the circumferential grooves 96c, 98c. In this example, block-to-block contact is made when ends 68 and 70 meet, as shown in Figure 13. This provides visual confirmation that coupling 62 is properly installed and avoids the need to specify screw torques for proper installation. The strip 64 deforms and compresses the seal 52 against the tube elements to ensure a fluid-tight joint. With the strip 64 in the deformed state, as shown in Figure 13, the size of the gaps 94 is smaller as compared to its size when the strip is not deformed, as shown in Figure 12. Note also in Figure 11, the coupling of the lips 54 with the tube elements when the seal 52 is compressed.
[040] Coupling mode 62 shown in Figure 8 can be used to join shoulder end tube elements 100, 102 as well as shown in Figure 14. In this example, radii 92 of channels 82 are equal to radii of curvature 100a, 102a of the tube elements 100, 102 adjacent to the shoulders 100b, 102b where the surfaces 90 of the channels 82 engage with the tube elements.
