Embodiments of the invention relate to connecting devices for connecting first and second tubes to each other in a sequential length wise relationship.
Handrails can be formed by connecting elongate tubes lengthwise to one another.
However, known methods and devices for effecting such connections can suffer from the problem that they eventually become loose, thereby allowing the tubes to become disconnected, or can cause the tubes connected to one another to be misaligned.
According to one aspect of this invention, there is provided a connecting device comprising: a main pad receivable by first and second articles to be connected to each other; first and second fasteners co-operable with the main parts, each of the first and second fasteners being urgeable relative to the main part to engage the articles when the main part is received by the articles, and to urge the main part into engagement with the articles to secure the first and second articles to the main part and thereby connect the first and second articles to each other.
According to another aspect of the invention, there is provided a method of connecting first and second articles to each other, comprising disposing the main part of a connecting device as described above in the end regions of the first and second articles, co-operatively engaging the first and second fasteners with the main part and thereafter urging the fasteners relative to the main part to engage the articles and urge the main part into engagement with the first and second articles to secure the first and second articles to the main part and thereby connecting the first and second articles to each other.
The connecting device may comprise a tube coupler for coupling tubes to one another to form a handrail. The connecting device may be in the form of a tube coupler for coupling tubes to one another to form a handrail.
The main part may define first and second apertures, and the first and second fasteners may be co-operably receivable through the first and second apertures. The method may comprise receiving the first and second fasteners in the first and second apertures and thereafter urging the first and second fasteners through the main part to engage the articles.
The main part may be urgeable relative to the first and second fasteners. The first and second fasteners may extend through the first and second apertures to engage the article and effect the aforesaid urging of the main part into engagement with the articles.
The first and second articles may be respective first and second tubes which are intended to be connected to each other in a lengthwise sequential relationship. The main part may be configured to be received in end portions of the first and second tubes. The method may comprise disposing the main part in the end portions of the first and second tubes.
The main part may be elongate having first and second end regions. The first aperture may be defined in the first end region of the main part. The second aperture may be defined in the in the second end region of the main part.
The first and second apertures may be threaded, and the fasteners may comprise threaded members which can threadably engage the threads of the apertures. Each fastener may comprise a threaded fastener, such as a bolt or a screw. The screw may be a headless screw, such as a grub screw.

The method may comprise inserting the first and second fasteners through first and second holes respectively, and thereafter screwing the fasteners into the first and second threaded apertures in the main part. The method may comprise forming the first and second holes in the first and second articles, for example by drilling.
The feature of the holes in the lower regions of the articles provides an advantage in the embodiments described herein that, in the event that the fasteners become loose, they fall into the holes, and thereby prevent the articles from becoming detached from each other.
Embodiments of the invention will now be described by way of example only, with reference to the accompanying drawings, in which: Figure 1 is a sectional side view of a first embodiment of a connecting device and first and second articles to be connected to each other; Figure 2 is a sectional side view showing the first and second articles connected to each other by the first embodiment of the connecting device shown in Figure 1; Figure 3 is a sectional end view showing the first embodiment of the connecting device and one of the articles; Figures 4A to 4C show the steps in a method of connecting first and second articles to each other; Figure 5 is a sectional side view of a second embodiment of a connecting device and first and second articles to be connected to each other; Figure 6 is a sectional side view showing the first and second articles connected to each other by the second embodiment of the connecting device shown in Figure 5; and Figure 7 is a sectional end view showing the second embodiment of the connecting device and one of the articles.
A connecting device 10 is shown which comprises a main part 12 having a substantially rectangular end profile (see Figure 3), and having a first substantially planar member 14 and a second substantially planar member 16 opposite the first substantially planar member 14. The first planar member 14 is substantially rectangular in configuration having opposite long edges 14A, 14B.
The main part 12 has a first end region 18 and a second end region 20. The first substantially planar member 14 defines a first aperture 22 in the first end region 18, and a second aperture 24 in the second end region 20.
The first and second apertures 22, 24 are internally threaded so that an externally threaded member can be threadably received thereby, as described below.
The second planar member 16 defines third and fourth apertures 26, 28. The third and fourth apertures 26, 28 are unthreaded and slightly larger than the first and second apertures 22, 24. The third aperture 26 is defined directly opposite the first aperture 22, and the fourth aperture 28 is defined directly opposite the second aperture 24.
The connecting device 10 directly further includes first and second threaded fasteners, which may be in the form of first and second threaded screws 30, 32, each having respective proximal ends 30A, 32A having driving formations 33. The first and second screws 30, 32 also have respective distal ends 30B, 32B.
The first screw 30 is threadably received by the first aperture 22, and can be screwed into the first aperture 22 so that it extends through the third aperture 26. Similarly, the second screw 32 can be threadably received by the second aperture 24, and can be screwed into the second aperture 24 so that the second screw 32 extends through the fourth aperture 28.
In the embodiments shown in the drawings, the connecting device 10 is in the form of a tube coupler, and is provided to connect first and second tubes 34, 36 to each other in an end to end sequential relationship, as shown in figure 2. The first and second tubes 34, 26 are used to form a handrail, although it will be appreciated that the connecting device 10 can be used to connect other types of tube to each other, such as scaffolding tubes.
Figures 4A to 4F show a method of connecting two tubes 34, 36 to each other in an end to end sequential relationship. The tube 34 has an end face 34A, and the tube 36 has an end face 36A. When the first and second tubes 34, 36 are connected to each other the end faces 34A, 36A abut against each other.
A first hole 38 is drilled in an end region of the first tube 34, and a second hole 40 is drilled in an end region of the second tube 36. The positions of the first and second holes 38, 40 are selected to provide access for the first and second screws, 30, 32 to the first and second threaded apertures 22, 24 in the main part 12, as explained below. The first and second holes 38, 40 are drilled in the undersides of the first and second tubes 34, 36.
The main part 12 in inserted into the end portion of the first tube 36. The first end region 18 of the main part 12 is received in the end region of the first tube 34 such that the first aperture 22 is aligned with the first hole 38.
The second end region 18 of the main part 12 is received in the end region ot the second tube 36. The main part 12 and the second tube 36 are positioned so that the hole 40 is aligned with the second aperture 24.
The first screw 30 is inserted through the first hole 38 to be received by the first aperture 22. The first screw 30 is then screwed into the first aperture 22 until the distal end 30B passes through the third hole 26 to engage the inside of the first tube 34.
The second screw 32 is inserted through the second hole 40 to be received by the second aperture 24. The second screw 32 is then screwed into the second aperture 26 until it passes through the fourth aperture 28 and the distal end 32 engages the inside of the end region of the second tube 36.
It will be appreciated that, if desired, in an alternative method, after the first hole 38 is aligned with the first aperture 34, the first screw can be inserted through the first hole 38 in the first tube 34, and screwed into the first threaded aperture 22 until the distal end 30B thereof engages the inside of the first tube 34.
Thereafter, the second tube 36 can be arranged over the second end region 20 of the main part 12 so that the second hole 40 is aligned with the second aperture 24.
The second screw 32 can then be inserted through the second hole 40 to be threadably received by the second threaded aperture 24, and then screwed into the second threaded aperture 24 until the distal end 32B engages the inside of the second tube 36.
The first and second screws 30, 32 are then tightened against the inside of the first and second tubes 34, 36, thereby urging the main part 12 relative to the first and second screws 30, 32 in the direction indicated by arrow A in figure 2. The result of this is that the edges 14A, 14B of the first planar member 14 engage the inside surfaces of the first and second tubes 34, 36.
Further tightening of the first and second screws 30, 32 into the first and second apertures 22, 24 cause the main part 12 to be engaged tightly with the inside of the first and second tubes 34, 36. This has the effect of securing the main part 12 to the first and second tubes 34, 36, thereby connecting the first and second tubes 34, 36 to each other.
When the first and second screws 30, 32 have been fully tightened, the inside of each of the first and second tubes are engaged by the distal ends 30B, 32B of the first and second screws 30, 32, and by the opposite edges 14A, 14B of the first planar member 14, as indicated by the arrows X, Y, Z in Figure 3.
In the event that the first and second screws 30, 32 become loose, the provision of the first and second holes 38, 40 in the undersides of the first and second tubes 34, 36 provides the advantage that the screws 30, 32 fall into the holes 38, 40.
Thus, so long as the loose screws remain attached to the main part 12, the connecting device 10 remains attached to the first and second tubes 34, 36, even though one or both of the screws 30, 32 has become loose, thereby still connecting the first and second tubes to each other.
The connecting device 10 provides a further advantage that the screwing of the first and second screws 30, 32 into the first and second apertures 22, 24, thereby urging the main part 12 into engagement with the inside surfaces of the tubes 34, 36, has the effect of aligning the first and second tubes 34, 36 with each other.
There is thus described a connecting device 10 which, in the embodiment described herein, can be used to connect first and second tubes 34, 36 to each other in an end to end sequential relationship which is secure and maintains the first and second tubes in correct alignment with each other.
Various modifications can be made without departing from the scope of the invention.
For example the first part 12 need not be of a square end profile but could be a sufficiently robust substantially planar member.
A further modification is shown in Figures 5, 6 and 7. In those Figures, many of the features shown in Figures 1 to 4C are present, and these features have been labelled with the same reference numerals as the corresponding features in Figures 1 to 40.
The embodiment shown in Figures 5, 6 and 7 differs from the embodiment shown in Figures ito 4C, in that the main part 12 is in the form of a C-shaped channel section, being devoid of the second substantially planar member 16. Instead, the main part 12 defines an open face 116 opposite the first planar member 14.
The embodiment shown in Figures 5 to 7 is used in the same way as the embodiment shown in Figures 1 to 40. However, the distal ends 30B, 32B of the threaded screws 30, 32 extend through the open end face 116, instead of through third and fourth apertures 26, 28.
