Abstract
ABSTRACT
A jointing device including arms which connect two elements together. The arms are elongated and of generally rectangular cross-section. One of the elements includes flanges with lips extending along the edges of the flanges and the other of the elements forms a clip. The lips form a mouth. Each arm is grooved near one end, the grooves extending transversely across one of the elongated faces of the respective arm. Said one end of each arm is bounded by a rolling surface which intersects said one surface of each arm and merges with the opposed surface. With the rolling surface in engagement, the arms diverge from said one end and, in this condition, can be inserted into, and removed from, said mouth. When the outer ends of the arms are moved together from this diverging position, the arms are brought into back-to-back relationship with the opposed surfaces juxtaposed. The lips are received in the grooves while the arms are held in back-to-back relationship in the mouth.
The arms are held in this relationship by the second element which straddles the arms. The lips are forced apart as the arms are brought into this relationship because the distance between the bottom of the grooves in greater than the initial distance between the lips.
The advantage of this invention is to provide joints and cantilever bracket supports which are easily assembled and disassembled.
It will be understood that joints between may be made between a variety of shapes with lipped channel openings, but also between one element incorporating a lipped channel and another element in a variety of other forms, such as round or square tube and the like and other devices providing a means of holding the two arms of the locking device in the locked position. The locking arms may be extruded or cast, the shape which protrudes may vary depending on its function.

The other of said further surfaces can intersect said one face at 45 .
The arms can further include a generally vee shaped further transverse groove in each of said one faces, that bounding face of each of these grooves which is furthest from said one end of the arm being obli~ue to said one face.
Additionally, a transverse, half round groove can be provided in each of said other faces, said half round grooves registering to form a hole when said other faces are juxtaposed.
Each rolling surface preferably has a spiral like form and comprises a first curved portion of relatively small radius, the first curved portion intersecting said one face, a second curved portion of relatively large radius merging with said other face, and a flat portion between the curved portions and merging therewith.
For a better understanding of the present invention, and to show how the same may be carried into effect, reference will now be made by way of example, to the accompanying drawings in which:-''.: '-:' . ' ~ ' :
, - ~.06601'7 Figure 1 diagrammatically illustrates a jointing device during assembly;
Figure 2 is a plan view showing the jointing device in its assembled condition;
Figure 3 is a pictorial view showing a further jointing device during assembly; and Figure 4 is a top plan view showing the device of Figure 3 in its assembled condition.
Referring firstly to Figures 1 and 2, the jointing device illustrated comprises a pair of arms 10, an element 12 providing a lipped channel, and a clip 14. Each arm 10 is a short section of aluminium extrusion and has a flat inner face 16 and a flat outer face 18. At the end thereof remote from the element 12 each outer face 18 is joined to the respective inner face 16 by means of a radiussed face 20, the face 20 being a "quarter round".
A semi-circular groove 22 is formed in each face 15 at a point which is spaced from the intersection between the faces 16 and 20 by a distance which is equal to approxi-20 mately one quarter of the length of the arm. A vee-shaped ~-groove 24 is provided in each of the outer faces 18, the grooves 24 being approximately midway between the ends of the arms. The faces of the grooves 24 meet the faces 18 at 45 angles.
Locating grooves 26 are provided adjacent the - inner end of each arm 10. Each groove 26 has a bottom surface which is parallel to the faces 16 and 18. The remaining surfaces which bound the grooves 26 are referenced 30 and 32. The surface 30 is at 90 with respect to the face 18 and the bottom surface 28 whereas the surface 32 slopes at an angle of approximately 45 with respect to the ~urface 28 and the face 18. Thus the mouth of the groove is wider than its base.
Radiussed surfaces 34 and 36 of each arm merge ;0~7 with opi)oslte cdges ol`il short, I`lat, c~ngled f`a~e 38 and respectively, merge wi~h the f`]at face 16 ar-ld intersect the face 18. 'Ihe l~lce 3~ ngled <It 4~ with re~pect to the f~lces ]6 ~nd 18 and the radiussed surr~ce 36 is a quarter round. Each fa~e 38 with the surface 34 and 36 on each side thereof constitutes a rolling surface.
The element 12 comprises two rlanges 40 which are joined by a web 42. J`he flanges 40 extend beyond the web 42 and, at their outer extremities, carry lips 44 which are directed towards one another to define the mouth of a channel 46 constituted by the web 42 and those portions of the flanges 40 which project beyond the web. It will be understood that the part of the element 12 which has no-t been shown can be a mirror image of that illustrated.
Certain dimensions of the element 12 in relation to dimensions of each surface 28, measured between its inter-sections with the surfaces 30 and 32, is equal to the thickness of the lips 44. Additionally, the dislarlec Lrom each surface 28 to the face 16 of the respective arrn is 20 ~reater than half the distance between the opposed surfaces of` the ]ips 44.
The clip 14 in its simplest form (see Figure 1) is a downwardly open channel having an upper web 48 and two depending flanges 50.
To assemble the jointing device, the two arms 10 are inserted into the channel 46 through the mouth defined by the lips 44i One way of doing this is to place the faces 38 in contact with one another which means that the arms 10 are then approximately at right angles to one another. In 30 this condition, the distance between the point on one arm at which the surface 30 intersects the face 18 and the correspond-ing point on the other arm is less than the ~idth of the mouth of the channel 46 measured between the lips 44. The arms are then presented to the mouth so that inner end portions ~ . - ' ;
~' , ' - .
0~7 of the clrms 10 ~nter the channel 46.
I'ressure is then exerted on the rree outer ends of the arms 10 so that the faces 16 are brough together.
During this movement the rolling surf`aces roll on one another. AS the arms move towards a parallel, face-to face condition the bottom surfaces 28 act on the lips 44 thereby distorting the charlnel 46 slightly by urging the lips 44 apart. As will be understood from the description above, the distance between the two surfaces 28, in the condition o~` the arms illustrated in Figure 2, is greater than the width of said mouth between the lips 44.
To maintain the arms 10 in the condition illustrated in Figure 2, the clip 14 is placed over the arms, the flanges 50 resisting any tendency of the arms to move baclc towards the position shown in Figure 1. Because the channel 46 has been distorted there is inherently a tendency for bhe inner ends of the arms 10 to be forced together which, iI
not restrained, would result in the arms moving baclc towards the position shown in Figure 1.
The surface 30 and 32 now lie inwardly and outwardly of the lips 44 and thus the arms 10 cannot be pushed further into the channel 46 or pulled out of the channel.
The web 48 of the clip 14 has a hole (not shown) therein which, by suitably positioning the clip 14 with respect to the arms 10, can be brought into alignment with the hole which is now defined by the co-operating grooves 22 (Figure 2). A screw, nail, pin or other fastening element can then be passed through the aligned holes so as positively to locate the clip 14 in position with respect to the arms 10 .
Two further holes 52 (see Figure 2) can be provided in the flanges 50 of the clip 14, these initially being aligned with those inclined faces of the vee-grooves 24 which are furthest from the element 12. Self tapping screws - , S entered in the iloles 52, by co-oper~lting with said inclined races, serve to displace the clip 14 firmly into engagement with the outer faces of the lips 44.
The slip 14 described can be placed over the arms 10 from above or pushed onto the juxtaposed arms 10 from the free ends of the arms.
Turning now to Figures 3 and 4, these illustrates a jointing device in which an element 12.1 oI` the same from as the element 12 of' Figure 1 is used to hold -the arms 10 in the position in which the faces 16 are in engagemen-t one with the other. 'I'he inner ends of the arms 10 are engaged with one of the channels 46 of a post 54 which includes a central core 56 and a plurality of radial arms 58. 'I`he arms 58 terminate in flanges 60 which in turn have lips 62 along their free edges. 'I'hese lips are equivalcnt to the lips 44 of Figures 1 and 2.
'I'he protrusions 64 formed on the inner ~'aces ot' the flanges 40 below the web 42 rest on the upper faces of the arms 10. A screw hole 66 is shown in Figure 4, this being aligned with the hole constituted by the grooves 22 when the element 12 is in position.
The frictional engagement between the arms 10 and the lips 44 or 62 prevents movement of the arms 10 with respect to the element 12 or post 54.
An advantage of the structure described is that vertical or horizontal joints can be added to a frame struct-ure without the necessity of disassembling any existing joints.
Where the clip 14 or element 12.1 extends horizontally it may support shelving, and if it extends vertically it may form a foot for the frame structure or part of a column. It will be understood that by appropriately shaping the clip 14 or element 12.1 it can be arranged to lie in an inclined psition.

The other of said further surfaces can intersect said one face at 45 .
The arms can further include a generally vee shaped further transverse groove in each of said one faces, that bounding face of each of these grooves which is furthest from said one end of the arm being obli~ue to said one face.
Additionally, a transverse, half round groove can be provided in each of said other faces, said half round grooves registering to form a hole when said other faces are juxtaposed.
Each rolling surface preferably has a spiral like form and comprises a first curved portion of relatively small radius, the first curved portion intersecting said one face, a second curved portion of relatively large radius merging with said other face, and a flat portion between the curved portions and merging therewith.
For a better understanding of the present invention, and to show how the same may be carried into effect, reference will now be made by way of example, to the accompanying drawings in which:-''.: '-:' . ' ~ ' :

Figure 2 is a plan view showing the jointing device in its assembled condition;
Figure 3 is a pictorial view showing a further jointing device during assembly; and Figure 4 is a top plan view showing the device of Figure 3 in its assembled condition.
Referring firstly to Figures 1 and 2, the jointing device illustrated comprises a pair of arms 10, an element 12 providing a lipped channel, and a clip 14. Each arm 10 is a short section of aluminium extrusion and has a flat inner face 16 and a flat outer face 18. At the end thereof remote from the element 12 each outer face 18 is joined to the respective inner face 16 by means of a radiussed face 20, the face 20 being a "quarter round".
A semi-circular groove 22 is formed in each face 15 at a point which is spaced from the intersection between the faces 16 and 20 by a distance which is equal to approxi-20 mately one quarter of the length of the arm. A vee-shaped ~-groove 24 is provided in each of the outer faces 18, the grooves 24 being approximately midway between the ends of the arms. The faces of the grooves 24 meet the faces 18 at 45 angles.
Locating grooves 26 are provided adjacent the - inner end of each arm 10. Each groove 26 has a bottom surface which is parallel to the faces 16 and 18. The remaining surfaces which bound the grooves 26 are referenced 30 and 32. The surface 30 is at 90 with respect to the face 18 and the bottom surface 28 whereas the surface 32 slopes at an angle of approximately 45 with respect to the ~urface 28 and the face 18. Thus the mouth of the groove is wider than its base.
Radiussed surfaces 34 and 36 of each arm merge ;0~7 with opi)oslte cdges ol`il short, I`lat, c~ngled f`a~e 38 and respectively, merge wi~h the f`]at face 16 ar-ld intersect the face 18. 'Ihe l~lce 3~ ngled <It 4~ with re~pect to the f~lces ]6 ~nd 18 and the radiussed surr~ce 36 is a quarter round. Each fa~e 38 with the surface 34 and 36 on each side thereof constitutes a rolling surface.
The element 12 comprises two rlanges 40 which are joined by a web 42. J`he flanges 40 extend beyond the web 42 and, at their outer extremities, carry lips 44 which are directed towards one another to define the mouth of a channel 46 constituted by the web 42 and those portions of the flanges 40 which project beyond the web. It will be understood that the part of the element 12 which has no-t been shown can be a mirror image of that illustrated.
Certain dimensions of the element 12 in relation to dimensions of each surface 28, measured between its inter-sections with the surfaces 30 and 32, is equal to the thickness of the lips 44. Additionally, the dislarlec Lrom each surface 28 to the face 16 of the respective arrn is 20 ~reater than half the distance between the opposed surfaces of` the ]ips 44.
The clip 14 in its simplest form (see Figure 1) is a downwardly open channel having an upper web 48 and two depending flanges 50.
To assemble the jointing device, the two arms 10 are inserted into the channel 46 through the mouth defined by the lips 44i One way of doing this is to place the faces 38 in contact with one another which means that the arms 10 are then approximately at right angles to one another. In 30 this condition, the distance between the point on one arm at which the surface 30 intersects the face 18 and the correspond-ing point on the other arm is less than the ~idth of the mouth of the channel 46 measured between the lips 44. The arms are then presented to the mouth so that inner end portions ~ . - ' ;
~' , ' - .
0~7 of the clrms 10 ~nter the channel 46.
I'ressure is then exerted on the rree outer ends of the arms 10 so that the faces 16 are brough together.
During this movement the rolling surf`aces roll on one another. AS the arms move towards a parallel, face-to face condition the bottom surfaces 28 act on the lips 44 thereby distorting the charlnel 46 slightly by urging the lips 44 apart. As will be understood from the description above, the distance between the two surfaces 28, in the condition o~` the arms illustrated in Figure 2, is greater than the width of said mouth between the lips 44.
To maintain the arms 10 in the condition illustrated in Figure 2, the clip 14 is placed over the arms, the flanges 50 resisting any tendency of the arms to move baclc towards the position shown in Figure 1. Because the channel 46 has been distorted there is inherently a tendency for bhe inner ends of the arms 10 to be forced together which, iI
not restrained, would result in the arms moving baclc towards the position shown in Figure 1.
The surface 30 and 32 now lie inwardly and outwardly of the lips 44 and thus the arms 10 cannot be pushed further into the channel 46 or pulled out of the channel.
The web 48 of the clip 14 has a hole (not shown) therein which, by suitably positioning the clip 14 with respect to the arms 10, can be brought into alignment with the hole which is now defined by the co-operating grooves 22 (Figure 2). A screw, nail, pin or other fastening element can then be passed through the aligned holes so as positively to locate the clip 14 in position with respect to the arms 10 .
Two further holes 52 (see Figure 2) can be provided in the flanges 50 of the clip 14, these initially being aligned with those inclined faces of the vee-grooves 24 which are furthest from the element 12. Self tapping screws - , S entered in the iloles 52, by co-oper~lting with said inclined races, serve to displace the clip 14 firmly into engagement with the outer faces of the lips 44.
The slip 14 described can be placed over the arms 10 from above or pushed onto the juxtaposed arms 10 from the free ends of the arms.
Turning now to Figures 3 and 4, these illustrates a jointing device in which an element 12.1 oI` the same from as the element 12 of' Figure 1 is used to hold -the arms 10 in the position in which the faces 16 are in engagemen-t one with the other. 'I'he inner ends of the arms 10 are engaged with one of the channels 46 of a post 54 which includes a central core 56 and a plurality of radial arms 58. 'I`he arms 58 terminate in flanges 60 which in turn have lips 62 along their free edges. 'I'hese lips are equivalcnt to the lips 44 of Figures 1 and 2.
'I'he protrusions 64 formed on the inner ~'aces ot' the flanges 40 below the web 42 rest on the upper faces of the arms 10. A screw hole 66 is shown in Figure 4, this being aligned with the hole constituted by the grooves 22 when the element 12 is in position.
The frictional engagement between the arms 10 and the lips 44 or 62 prevents movement of the arms 10 with respect to the element 12 or post 54.
An advantage of the structure described is that vertical or horizontal joints can be added to a frame struct-ure without the necessity of disassembling any existing joints.
Where the clip 14 or element 12.1 extends horizontally it may support shelving, and if it extends vertically it may form a foot for the frame structure or part of a column. It will be understood that by appropriately shaping the clip 14 or element 12.1 it can be arranged to lie in an inclined psition.
