CONNECTOR
This invention relates to a connector for forming an inter-connection between two members at least one of which is a tubular member.
The invention relates in particular, but not exclusively, to a connector for use with a tubular member to facilitate provision of an assembly, such as a handrail assembly, in which the connector presents an outer surface which is a substantially smooth continuation of the outer surface of the tube. The invention endeavours to provide a connector suitable for said purpose and which is of relatively low cost as well as being simple to employ when constructing an inter-connected assembly, such as an assembly comprising two tubular members.
The invention seeks also to provide a connector which, in accordance with at least some embodiments, may be employed for connecting to a tube of an internally seamed type.
In accordance with one aspect of the present invention there is provided a connector for connecting two members at least one of which is a tubular member, said connector comprising two component parts, one part being a connector housing member and the other part being a connector insert member, the connector housing member comprising an annular body portion and two limb portions between which the body portion lies, as considered in the length direction of the connector housing member, the annular body portion having an outer face, said outer face optionally being of a shape and dimension for conforming substantially to that of at least one of the two members to be connected by the connector, and the limb portions each having an outwardly facing abutment surface which lies inset from the outer face of the annular body portion and, in use, abuts an inner face of one of the two members to be connected by the connector, the annular body portion defining a through-bore through which the connector insert member extends, said insert member comprising a central portion having an outer face which, in use, confronts an inner face of the housing body portion and two limb portions between which said central portion lies, as considered in the length direction of the insert member, each limb portion of the insert member having an outwardly facing abutment surface which, in use, lies axially outwards of the annular body portion of the connector housing member when the central portion of the insert member is aligned with the annular body portion of the housing member, the annular body portion comprising an aperture in the wall thereof whereby locking means provided within the connector isoperable to urge the limb portions of the insert member away from the limb portions of the connector housing member such that, in use, the outwardly facing abutment surface of each of said limb portions of the insert member may each bear firmly against inner faces of said two members thereby to form an inter-connection between said two members.
In order that the limb portions of the connector housing and insert members may bear firmly against inner surfaces of the two members to be interconnected it is required that the outer face of the central portion of the insert member should not bear firmly against and preferably should merely confront but be slightly spaced from the inner face of the housing body portion. Optionally, and if necessary having regard to the relative positions of inner surfaces of said two members and the confronted inner face of the housing body portion, the outwardly facing abutment surface of each limb portion of the insert member may, in use, tie outwards of the outer face of the central portion of the insert member.
Preferably the abutment surfaces of the limb portions of the component housing member lie inset from the outer face of the annual body portion by no less than, and more preferably at least in part by a distance equal to, the thickness of a tubular member with which the connector is to be employed.
Substantially all, or only a part of an outer face of each said limb portion may act as an abutment surface for abutting the inner surface of a tubular member.
A part of the outer surface of a limb portion of the connector housing member may lie inwards from the outer face of the annular body portion by greater than the nominal wall thickness of a tube to which the connector is to be secured thereby to provide a space for accommodating an internal seam of an internally seamed type of tubular member.
The limb portions of the connector housing member preferably are circumferentially discontinuous over at least a major part, and more preferably over the whole of their respective axial lengths.
The limb portions of the connector housing member may each define a pair of guide surfaces for guiding movement of the connector insert member when the locking means is employed to urge the limb portions of the insert member away from the limb portions of the connector housing. It is not essential that the connector housing member acts to guide the insert member and in an alternative construction the insert member, as viewed in transverse cross-section, may rest on or lie above the limb portions of the connector member.
The aperture in the wall of the annular body portion of the connector housing member may be provided with a screw thread formation or otherwise shaped to provide location for locking means, such as a grub screw, insertable in said aperture and rotatable to cause an end of the screw to bear against a reaction surface defined by an inner face of the central portion of the connector insert member. Alternatively, for example, said aperture may provide access to locking means provided within the confines of the annular body portion to operate said locking means and urge apart the respective limb portions of the connector insert and housing members.
Typically the connector annular body portion may have a cylindrical outer face for use in connecting a pair of circular cross-section tubes, but the annular body portion of the connector housing member may, for example, be of a square or other polygonal cross- sectional shape selected to conform with the cross-sectional shape of a tubular member to which a connection is to be formed.
Each connector member may be of a unitary construction in which the limb portions are integral with the central or body portion provided therebetween.
Each connector member may, for example, be formed by casting of a material such as aluminium or iron, or may be moulded from a mouldable material such as an engineering plastics. The connector members alternatively may be formed by machining of stock material.
The abutment surfaces of the limb portions may be smooth or as-cast surfaces, or may be specially formed with a textured finish to provide an enhanced frictional engagement with the internal surface of a tubular member, particularly in any installations in which the connector is to resist significant axial forces tending to separate two inter-connected members.
Although the connector of the present invention is particularly suitable for forming an inter-connection between two tubes, in particular two tubular members of substantially equal outer diameter corresponding to the outer diameter of the annular body portion of the connector housing member, one of the inter-connected members may, for example, be a mounting or flange which is formed with a bore to receive a pair of said limb portions and which does not necessarily have an outer surface of a shape and size corresponding with that of said annular body portion.
It is also envisaged that the annular body portion may have an outer surface which is non-cylindrical, for example, which is curved as considered in longitudinal cross-section, and with axial end regions of the surface optionally corresponding in dimensions with the ends of the inter-connected members.
The connector may be of a rectilinear type for forming a straight, in-line connection of two tubular member or may be curved or angled in its length direction for forming an inter-connected assembly in which one tubular member is angled relative to another. A connector member may comprise at least one limb portion which is curved along the length thereof for insertion into a correspondingly curved end of a tube. In the case of a connector for forming an in-line straight connection, the annular body portion of the connector housing member will typically define a pair of annular and substantially planar abutment surfaces for contact by ends of respective tubes, but in the case of a connector for forming a curved or angled inter-connection, the annular body portion may define a pair of abutment shoulders which lie in planes angled relative to one another.
Embodiments of the present invention will now be described, by way of example only, with reference to the accompanying diagrammatic drawings in which:-Figure 1 is a perspective view of a connector housing member of a connector in accordance with a first embodiment of the present invention; Figure 2 is a perspective view of an insert member for use with the housing member of Figure 1; Figure 3 is a perspective view showing the insert member in situ with the housing member; Figure 4 is a side view of the assembly of Figure 3 in the direction of arrow X of figure 3; Figure 5 is a perspective view of a housing member in accordance with a second embodiment of the present invention; Figure 6 is a side view in the direction of arrow X of Figure 5; Figures 7, 8 and 9 are respectively top, bottom and end views of the housing member of Figure 5; Figure 10 is a longitudinal sectional view on the line X -X of Figure 7; Figure 11 is a perspective view of an insert member for use in conjunction with the housing member of Figures 5 to 10; Figure 12 is a side view in the direction of the arrow X of Figure 11; Figures 13 and 14 are respectively top and bottom views of the insert member of Figure 11, and Figure 15 is a section on the line X -X of Figure 12.
The connector 10 of Figures 1 to 4 comprises a housing member 11 and an insert member 12 each formed from malleable cast iron.
The connector is intended to be used for the purpose of joining confronting ends of two tubes 31 (see fig.4) each of equal and circular cross-section. The housing member comprises an annular body portionl3 having an outer cylindrical surface 14 of a diameter corresponding to the outer diameter of the tubes to be inter-connected by the connector 10. The annular body portion 13 defines at the axial ends thereon a pair of annular abutment surfaces 25 in the form of shoulders having a radial dimension corresponding substantially to the wall thickness of the tubes which are to be inter-connected by the connector.
The annular body portion 13 lies between two limb portions 15 each substantially of a C shape in transverse cross-section. The outer surface 16 of each limb portion is of a part-cylindrical shape and the inner surface 17 is of a U shape comprising a part-cylindrical surface which inter-connects a pair of substantially planar and mutually parallel surfaces 18 which serve as guide surfaces for guiding movement of the insert member 12.
The insert member 12 comprises two limb portions 20 which extend axially outwardly from a central, recessed portion 21.
Each limb portion 20 has an outer surface 22 of part-cylindrical shape corresponding in curvature substantially to that of the inner surface of each of the tubes to be inter-connected by the connector 10. The outer surface of the recess portion 21 has a curvature corresponding substantially to that of the inner surface of the annular body portion 13 of the housing member 11. A pair of shoulders 23 lie between the recess portion 21 and the limbs 22 and are spaced apart by a distance slightly greater than the axial dimension of the annular body portion 13 of the housing member 11.
An inner face 24 of the recess portion comprises a zone (not shown) which serves as an abutment face. The annular body portion 13 of the housing member comprises a screw-threaded aperture 30 the axis of which extends substantially parallel with and midway between the guide faces 18.
In use of the connector to inter-connect two tubes a grub screw is inserted through the screw-threaded aperture to bring the end of the grub screw into contact with the abutment zone of the inner surface 24 of the insert member.
Thus the part-cylindrical outer surfaces 22 of the insert memberare urged away from the outer surface 16 of each housing member limb portion 15. In consequence the part-cylindrical surfaces of the limb portions of the housing and insert members are caused to bear firmly in frictional engagement with the internal surface of each of the tubes to be inter-connected by the connector 10. In the resulting assembly, irrespective of tolerance variations of the internal diameter of the tubes, the outer surface 14 of the connector is able to provide a circumferentially continuous surface aligned with the outer surfaces of the inter-connected tubes.
In accordance with a second embodiment of the present invention a connector comprises a housing member 40 as shown in Figures 5 to 10 and an insert member 41 as shown in Figures 11 to 15.
The housing member 40 comprises an annular body portion 42 which corresponds in general with the annular body portion 13 described above in respect of the first embodiment of the present invention.
Two limb portions 43 depend in opposite directions from the annular body portion 42 and each comprise an internal face 44 substantially similar to the U shaped internal face 17 described in respect of the first embodiment.
However the external face 45 of each limb portion 43 differs and comprises a part-cylindrical portion 47 and a pair of mutually parallel face regions 46 inter-connected by the part-cylindrical surface portion 47.
The annular body portion 42 is formed with a screw-threaded aperture 48 the axis of which is substantially parallel with and lies substantially midway between the outer faces 46 of the limb portions.
The insert portion 41 comprises a recess region 50 from which a pair of limb portions 51 depend.
In a manner similar to that described in respect of the first embodiment of the invention, each of the limb portions 51 comprises a part-cylindrical outer surface 42 having a curvature corresponding substantially to the internal curvature of the tubes to be interconnected by the connector. In contrast to the shoulders 23 described in respect of the first embodiment of the invention and which extend substantially at right angles to the inter-connected surfaces 21,22 of the recess and limb portions, in this embodiment the outer surface of the recess portion connects with outer surfaces 52 of the limb portions via curved shoulder regions 53 ( see Figure 12).
In contrast to the arrangement of the first embodiment of the invention in which the insert portion lies between confronting surfaces 18 of the housing member, in this embodiment the transverse width of the insert portion, as shown in Figures 13 and 15, corresponds with the spacing of the outer surfaces 46 of the housing member limb portions 43. Thus longitudinal edge regions 54 of the insert member 41 rest on or, in use, may lie above the longitudinal edges 55 of the housing member limb portions 43.
In use of the housing and insert members of the second embodiment of the invention, a grub screw is inserted through the screw-threaded aperture 48 and caused to bear against an abutment surface region 56 of the insert member. In consequence the outer surfaces 52 of the insert member limb portions are urged away from the part-cylindrical surface of the housing member limb portions 43 to bear firmly in frictional engagement with the internal surfaces of the ends of a pair of tubes.
In the second embodiment of the invention, in the final assembly of inter-connected tubes, a small space will exist between the internal wall of each tube and each planar outer face 46 of the housing member limb portions.
That space is of potential advantage in the case of joining two tubes of an internally seamed type in so far as that space may be used to accommodate the internal seam and thereby obviate any need to remove the seam material from an end of each tube prior to forming the inter-connection.
