Definitions
- the invention relates to mechanical connectors.
- the invention relates more particularly to 'structural' connectors for fixing pipes and the like together end-to-end in-line or angled with respect to one another, and for fixing pipes to a wall or other planar surface.
- connectors that are available do not usually provide much resistance to banding moments at the end of the pipe.
- the connectors necessarily require different basic components, and are not simple in operation or assembly.
- the connectors are not ready to be released from the tubes to be reassembled in general.
- a releasable connector for connecting to one end of a tube comprising a split elongate sleeve that fits snugly inside the tube, convergent members that are mounted at opposite ends of the sleeve, and an operating rod extending centrally through the sleeve arranged to move the convergent members towards each other in use to urge the sleeve radially outwards to bear against the inside of the pipe and fix the connector to the pipe in an operative configuration.
- the convergent members might be frusto-conical. However, they could be any combination of frusto-conical and frusto-pyramidal.
- the elongate sleeve is preferably split into two equal parts. The sleeve parts are preferably resiliently held together radially by a strap that surrounds a periphery of the sleeve.
- the elongate sleeve is preferably cylindrical and fits into cylindrical cavities at the ends of respective pipes.
- the elongate sleeve may be rectangular in cross-section to more efficiently connect to pipes having rectangular cross-section cavities at least in their ends.
- the sleeve can be formed by material with certain elasticity with cross-section of its outer surface to be the same or even a little larger than that of the internal section of the tube.
- the elasticity and the slit and troughs enable the sleeve to be compressed and inserted and adhered to the internal surface of the tube. This achieves friction between the internal surface of the tube and the external surface of the sleeve. I n this case the movement of the convergent members along the rod towards each other cause the increase of pressure between the tube and the sleeve.
- the sleeve can be used to connect pipes having regular or irregular cross-sectional cavities.
- cones, or pyramids, or a cone and a pyramid in the connector in some embodiments is independent of the internal shape of the tube. In some cases, it depends on operating conditions.
- the angle of the sides of the convergent members is typically between 25° and 65°. As the two members move towards each other, they will adjust themselves automatically, and squeeze the ends of the sleeve, which makes both ends of the sleeve as well as the whole sleeve adhere to the internal surface of the tube. When the two locking bodies move outwards from each other, the large vertical angles of the locking bodies enable the securing body to slide along the slant surface of the convergent members. This releases the connector from the tube.
- the use of two members or 'locking bodies' will remove the defect of the adhering of one end of the sleeve to a plate, when only one locking body is used to secure the sleeve to the tube, especially when the vertical angle of the locking body is large. That is the securing effect only occurs at one end .
- the use of single locking body with a small wall angle can also be used to substitute the use of two locking bodies.
- the connector has an arm formed with a conical end or a pyramidal end with polygonal cross-section to provide one cone or one pyramid.
- the connector may have two arms each with a conical end or a pyramid end with polygonal cross-section to form a respective cone or pyramid, and in which the connector is arranged to join two pipes together.
- the connector may have three or more arms and can be arranged to connect three or more pipes together with longitudinal axes of the two or more of said pipes angled with respect to one another.
- the arm may have an anchor arranged to be mounted and restrained by a cavity of a planar surface for mounting the arm to the planar surface, in which the operating arm comprises a bolt partially exposed extending out of one end of the connector into the cavity, when the connector is in its operative configuration.
- a centrally mounted threaded nut may be entrapped within the connector and accessible from exterior of the connector when the connector is in its operative configuration.
- the operating rod may be anchored in an opened-sided body that provides one of the convergent members with a conical or polygonal cross-section at one end and allows the operating rod to be inserted sideways into the body.
- the body can be split into two parts along the axial direction in case of need.
- the operating rod can be placed between the two parts
- the two parts of the body are preferably resiliently held together radially by a strap that surrounds periphery of the body. This enables the operating rod to be placed in a multiple-arm connector, especially when the arms are linearly opposite to each other.
- the split body and the sleeve are well confined by the tube in the operating configuration.
- the body may have convergent members in the form of a cone or pyramid with polygonal cross-section at each end, respectively forming part of a connector for connecting two like pipes end to end, in which a central part of the body has a region with an external diameter and shape equal to the outside diameters and shape of the two pipes to be connected.
- a releasable connector for joining two pipes of different internal diameter end-to-end may include two connectors and a single operating rod extending between two sleeves arranged to bear against respective inner surfaces of the pipes, in which the operating rod has a fixed conical head at one end and a threaded nut at the other end and such that the sleeves are urged outwards by relatively rotating the pipes to fix the pipes together.
- Embodiments of the invention provide connectors, which can be releasable in case of need, from a tube or a hole in wall say.
- the connectors can be used to capture screwed nut inside the tube or hole, although connectors are normally used for connecting two tubes together end to end.
- a multiple structural node connector can be provided where a multiple arm connector connects several tubes together.

- Figure 15 shows a schematic sectional view of a four-arm embodiment.
- a plate 102 has central hole 117.
- a screw 101 has a head 108 and a thread stem 109 extending through the hole 117.
- a first locking member 103 Surrounding the stem 109 is a first locking member 103 having a conical part 111 and cylindrical part 110 and central hole for the stem 109.
- a securing member (or split sleeve) 104 has two like semi- cylindrical bodies 104a and 104b, forming a 'split sleeve', with conical cavity 112 and hexagonal pyramidal cavity 115 at their ends.
- the shape of the conical cavity 112 is similar to the shape of the conical locking parts 111 and 103, but a little smaller.
- the conical locking body lies between the plate 102 and the securing member 104, having the conical part 111 contiguous to the conical cavity 112.
- the securing bodies 104a and 104b rest against each other along their edges as shown by the dashed lines along the center of the figure.
- the securing member 104 fits snugly inside and extends along adjacent the end of a tube 106.
- a strap 107 lies in a central peripheral trough 116 formed in an outer surface of the securing member 104. An outer surface of the strap fits flush with or lies within the outer surface of the securing member 104.
- the strap 107 is elastic, and retains the two securing bodies 104a and 104b radially together.
- the securing body 104 lies between the conical locking body 103 and the pyramidal locking body with hexagonal cross-section 105.
- the second locking body 105 has a hexagonal cylinder part 114, a pyramidal part with hexagonal cross-section 113 and a central threaded hole 120.
- the pyramidal part 113 of the pyramidal locking body is contiguous with the cavity 11 5 at the other end of the securing member ,104.
- the shape of the pyramidal cavity 115 of the securing member 104 is similar to the shape of its counter pyramidal part 113 of the locking body 105.
- the connector is inserted into the tube 106 as shown in Figure 1 .
- a screwdriver or similar may be applied to the head 108 of the screw 101 .
- the screw 101 may be rotated appropriately so as to draw the first and second locating bodies 103 and 105 towards each other.
- the opposing locking bodies 103 and 105 will be urged against the cavities 112 and 115.
- the securing bodies 104a and 104b will be forced radially outwards to grip against the inside of the tube 106. I n this way, the connector grips the tube and so is secured therein so as to prevent movement thereafter of the tube away from the connector, i.e. , to the left in the Figure.
- the screwdriver is inserted to undo the screw 101 so that the conical locking body 103 and pyramidal locking body 105 are moved away from one another. This removes the radially outward compression force applied by the securing bodies 104a and 104b. Tension in the elastic strap 107 restores the securing bodies to the original position, allowing the securing bodies to be slid out of the end of the tube 106.
- locating pins may be provided at the interface extending along (the dashed line) between the securing bodies 104a and 104b to prevent the securing body 104a from sliding longitudinally relative to the securing body 104b.
- the securing member 104 is formed by material with some elasticity such as a plastic material, and one of the interfaces between securing bodies 104a and 104b may then be welded together, allowing the bodies to hinge along the interface.
- longitudinal pressure applied by the conical locking body and pyramidal locking body 103 and 105 will make the securing member deform at least to some extent radially outwards. Deformation at the outer surface of the securing member causes the outer surface to be urged against the inside of the tube to establish frictional grip and secure the connector in the tube.
- the tube is arranged to be connected to the plate 102.
- this connector can be arranged to attach a tube a planar surface of some other object, if required. Without the plate 102, the connector can still provide a friction grip with the tube 106 by rotation of the screw.
- Figure 2 shows an alternative embodiment of the invention shown in Figure 1 , for fixing a screw with the stem of the screw extending out from the tube.
- a screw 201 has a screw head 202, a conical base 203 and a stem 207, which conical base 203 of the screw 201 acts as the conical part 111 of the first conical locking body 103 in Figure 1 .
- the conical base 203 of the screw 201 is contiguous with a concave cavity 209 of the securing member 204.
- On the other end of the securing member 204 is the locking body 205, having a hexagonal threaded nut 208 in an indentative hole 211 in its base.
- the conical locking body 205 has a cylindrical part 213 and a conical part 212 and a hole 214, having a hexagonal cylindrical slot 211 at the base of a cylindrical part 213.
- the hexagonal nut 208 is positioned in the hexagonal hole 211 on the stem
- the locking body 205 and the screw-nut 208 function similarly as the pyramidal locking member 105 in Figure 1 .
- the cross section of the sleeve 204 can be the same or even a little larger than the internal cross-section of the tube.
- the sleeve 204 here is a single object with certain elasticity.
- the openings of the troughs are positioned outwards from the hole 218. Under force the slit 220 and troughs 221 shrink, and this enables the sleeve as well as other parts of the connector to be inserted into the tube.
- the connector is inserted into a tube 206 with the stem 207 of the screw 201 extending out of the tube.
- a suitable wrench can rotate the conical locking body 205 and the entrapped nut 208, which are drawn along the threaded stem 207.
- the connector is thus operated in the same manner as in Figure 1 , so that the connector can be secured in the tube.
- This fixes a screw with an exposed thread stem 207 at the end of the tube 206.
- a securing member with a slit and troughs can also be used. Friction between the sleeve and the interior of the tube 206 prevents the sleeve from rotating inside the tube, when the wrench rotates the conical locking body 205.
- the operation of the connector can still be the same.
- the securing member 204 can be adjusted to be able to be snugly inserted into the bore of the tube 206. This is done by rotating screw 201 , so that the two locking bodies, conical base 203 of the screw and the conical locking body 205 with the nut 208, suitably compress the securing bodies 204.
- the surface of the securing member is adjusted so that some friction will exist when the connector is first inert in the end of the tube. Thus when the screw is first tightened , the securing member will not rotate inside the tube.
- Part of the surface of the cylinder part 213 of the conical locking body may have flat surfaces or other suitable shapes, for example the cylinder part may be hexagonal in cross-section. This facilitates a wrench to grip the conical locking body 205 during locking of unlocking of the connector.
- the tube provided with an exposed screw at its end can be used to connect the tube against a surface of a plate using separate nut.
- the tube can also be connected another tube, where the tube with the screw at its end acts as a special screw for another connector.
- the connector can also be used to fix an exposed screw in an aperture in an object.
- the operation of the connector can also be carried out with a screwdriver or other suitable driving implement from the left-hand side through the tube.
- the screw head is threaded forward towards the locking member 205 similar to that in Figure 1 .
- the connector is secured to the tube.
- Figure 3 shows a third embodiment of the invention for connecting a threaded nut to a tube.
- FIG. 3 is a modification of the connector shown in Figure 1 .
- Main bodies 310a and 310b are formed integrally with securing bodies 304a and 304b.
- a screw head 302 lies inside the main bodies 310a and 310b.
- a cavity 312 is provided to receive a hexagonal screw nut 309.
- a conical base 303 of the screw head 302 acts as the first conical locking body.
- a conical locking body 305 with the threaded nut 308 in a slot 315 at the base cylinder 314 acts as the second conical locking body.
- the connector, with the screw nut 309 in cavity 312, is inserted into the tube 306.
- a screwdriver or other implement can pass through the aperture 313 and the central hole of the nut 309 for fixing the connector inside the tube 306.
- the described connector can be easily connected to a plate by a screw passing through the plate.
- the tubes in Figures 2 and 3 can be connected directly end to end.
- the tubes may be connected together with an intervening plate, where the plate acts as an adapter where required.
- Such combination of tubes and plates, with holes in the plates can be used to build shelves that can be easily assembled and disassembled using the described connectors.
- Figure 4 shows the fourth embodiment of the present invention.
- the connector includes a right-angular metallic body 401 with conical heads 402, having access holes 408 at right angles to each other, for receiving the locking screw 404. In the arms there are holes 418 along the axial direction to receive the stem of the screw 404.

- the bodies 609 and 610, and the conical heads 612 and 613, and the second screw 604 in the screw hole are then fixed together by the strap 615.
- FIG. 7 shows another embodiment of the present invention for multiple arm connector that has two arms perpendicular with each other.
- the arm in the vertical direction is the same as that in Figure 6, while the arm in the horizontal direction has body parts 709 and 710 integrally formed with securing members 712 and 713, which body is halved across the horizontal plane 711 in an axial direction.

- the arms are then inserted into the respective tubes (not shown here). The rotation of the screw, using a screwdriver, will secure the tubes to the connectors.
- Figure 13 shows another preferred embodiment of the present invention for fixing a tube to a planer surface.
- a tube 1305 with a nut 1304 is provided in the manner described with reference to Figure 3.
- a nut 1304 in the tube 1305 is threaded onto a screw 1302. This connector arrangement can be used to stabilize (i.e. attach) tabular legs to a portable stool or a table.
- the tubes or pipes may have rectangular cross-sections, and if solid be formed with cavities at their ends to receive the connectors that are either as described, or rectangular.
- the split sleeve will normally, but not necessarily, be also provided with a rectangular cross-section.
- a rectangular cross-section generally provides better friction and gripping against inside surfaces of the tube and so is more reliable when the connectors are in their operative configurations.
- a rectangular split sleeve is preferably formed of two like parts for convenience in use, but may be formed of four like parts, if preferred or desired.
- the split bodies are normally bodies formed with a conical end surface or a pyramidal end surface to receive the opposing cones, or opposing pyramids with polygonal cross-section, or cone and pyramid with polygonal cross-section. It is possible to 'omit' the conical end surfaces or pyramid end surfaces, in which case the cones and pyramids will still act, as they are drawn towards each other, to urge the split sleeves radially outwards.
- the split body may simply have a central passage of sufficient diameter or length to receive the noses of the cones or pyramids.
- the outer surfaces of the sleeves fit firmly against inner surfaces of the tubes when the connectors are secured in position. It will be appreciated that the outer surfaces of the sleeves normally extend well into the ends of the tubes and this provides an extended support for the tubes adjacent their ends that helps resist any bending moments applied to the ends of the tubes. This also applies where the connectors are used to fix and locate a tube to a planar surface formed by part of a wall or a tabletop.
- the 'securing bodies', or split sleeves are made up of two like generally semi-cylindrical parts.
- the securing bodies may be made up of the three or more part that are held together, when assembled for insertion into the end of a tube or pipe, and make up a hollow cylinder.
- the connector can be locked to the tube with normal or even irregular cross-section.
- the connector can be secured directly to a tube as in Figure 1 , Figure
- the connector can also to have an arm like the one in Figure 1 and Figure 3.
- the arm might be used to attach some accessories to the tube for effectively connecting the tube to another object.
- the body of the connector can have two arms as shown in Figure 4, Figure 5, Figure 6, Figure 7, Figure 8 and Figure 9. In this case the connector can effectively connect two tubes together linearly or at an angle.
- a multiple arm connector can be formed by providing several arms to the body using the methods described in Figure 1 to Figure 10. Three such embodiments are shown in Figures 14 and 15 respectively. Different adaptations might then enable the screws or operating rod to be placed properly inside the connector for effective operation.
- Each arm might be a connector by itself for connecting to a tube to work under the same basic principle as described previously.
- the method used to connect the smaller tube to the larger tube in Figure 9 can also be used to connect a tube to an arm of the connector, i.e. by rotation of the tube to secure the tube to the connector. There ought to be a definite friction between the inner surface of the sleeve and the dependent convergent body.
