Description

BACKGROUND OF THE INVENTION

(1) Field of Invention

The present invention relates to a frame connection and, more particularly, to a frame connection for connecting members of a frame without visible fixings.

(2) Description of Related Art

Many structures such as fence panels, screening panels, balustrades, and railings comprise an external frame supporting a plurality of cross members. The members forming the frame generally comprise extrusions that are cut at 45 degrees at the ends and secured to form the frame.

A common method of joining the ends of the extrusions is to insert a single angle piece into the end of each of the extrusions and screw through the sides of the extrusions into the angle piece to hold the extrusions together. While such an arrangement is relatively simple to assemble, the corner connection can tend to become loose due to flexing of the extrusions in use, Further, this arrangement can result in visible fixings, which detracts from the appearance of the frame.

Thus, a continuing need exists for a frame connection for connecting members of a frame that provides simple assembly and a secure connection, without visible fixings.

(1) Specific Details

Referring, to the figures, there is shown a frame connection 10 for connecting elongate members of a frame assembly 12. In the embodiment of FIGS. 1 to 5, the frame assembly 12 comprises as first frame portion 14 and a second frame portion 15. Each of the first and second frame portions 14 and 15 comprise a plurality of elongate members mounted to a vertical surface, such as a wall around a window. A plurality of louvre blades 16 are secured between the first frame portion 14 and the second frame portion 15.

In the embodiment shown, each of the elongate members comprises an extrusion having a cross sectional shape as shown in FIGS. 2 and 3. The invention comprises a frame connection 10 for connecting a pair of adjacent elongate members and will be described with reference to a first elongate member 18 and a second elongate member 20, as shown in FIG. 1b.

With reference to FIGS. 2 and 3, each of the first and second elongate members 18 and 20 is formed by parallel first and second end walls 22 and 24. The end walls 22 and 24 are interconnected by first and second inner walls 26 and 28. The first and second inner walls 26 and 28 are each offset from the ends of the first and second end walls 22 and 24 such that longitudinal channels are defined. A first channel 32 is defined adjacent a first side of the elongate member between the first inner wall 26 and the first ends of the first and second end walls 22 and 24. A second channel 34 is defined adjacent a second side of the elongate member between the second inner wall 28 and the second ends of the first and second end walls 22 and 24.

In transverse cross section, the first and second elongate members 18 and 20 are therefore, generally of an H-shape. The first and second channels 32 and 34 are closed off at the first and second sides of the elongate members by side cover members 36. Each of the first and second side walls 22 and 24 is provided with longitudinal slots 38 along the edges thereof such that these slots 38 can receive complementary ribs provided on the side cover members 36. The side cover members 36 can be press fit across the channels 32 and 34 to provide a finished appearance to the first and second elongate members 18 and 20.

The first and second elongate members 18 and 20 are secured together at first ends thereof by a pair of connection members 40, as shown in FIG. 4. Adjacent ends of the first and second elongate members 18 and 20 are angled such that the end of the first elongate member 18 meets the end of the second elongate member 20 in a mitred joint. In the embodiment shown in which the connection is perpendicular, the ends of the each of the elongate members 18 and 20 are cut at 45 degrees.

The connection member 40 comprises a. first end portion 42 that is to be received in the first channel 32 or the second channel 34 of the first elongate member 18 and a second end portion 44 that is to be received in the corresponding channel 32 or 34 of the second elongate member 20.

The first end portion 42 comprises a first planar member 43 having opposed parallel sides 46 and a distal end 47. The second end portion 44 comprises a second planar member 45 having also parallel sides 46 and a distal end 47. The first and second planar members 43 and 45 are oriented in the same plane and opposed sides 46 of the first planar member 43 are perpendicular to opposed sides 46 of the second planar member 45. That is, the connection member 40 forms generally an L-shaped plate.

The first and second channels 32 and 34 of the elongate members 18 and 20 are of complementary shape to the first and second end portions 42 and 44 of the connection members 40. That is, in cross section the length of the channels 32 and 34 between the first and second end walls 22 and 24 is relatively large compared to the width between the inner wall 26 or 28 and the side cover member 36.

In use, the first end portion 42 of a first connection member 40 is inserted into the first channel 32 of the first elongate member 18 and the Second end portion 44 of the first connection member 40 is inserted into the first channel 32 of the second elongate member 20. The first end portion 42 of a second connection member 40 is inserted into the second channel 34 of the first elongate member 18 and the second end portion 44 of the second connection member 40 is inserted into the second channel 34 of the second elongate member 20.

The opposed sides 46 of each of the first and second end portions 42 and 44 of the connection members 40 are provided with a plurality of protrusions 48 thereon, The protrusions 48 engage with the inner sides of the end walls 22 and 24 such that the connection members 40 must be press fit into the channels 32 and 34. The connection members 40 may for example, be constructed of a plastic based material with the elongate members 18 and 20 being metal extrusions. The protrusions 48 will, therefore, deform as they engage with the inner sides of the end walls 22 and 24. In the embodiment shown, the protrusions 48 each comprise a triangular shaped protrusion.

The connection members 40 are also provided with a plurality of holes 50 in both the first and second end portions 42 and 44 thereof. Once the connection members 40 are pressed into the channels 32 and 34, a suitable fastener, a non-limiting example of which includes a threaded fastener, may be inserted through one or more of the holes 50 into the inner wall 26 or 28. By drilling into the inner wall 26 or 28, the threaded fastener can further securely connect the connection member 40 to the elongate member 18 or 20 before the side cover member 36 is pressed into place.

FIGS. 9 to 12 show a second embodiment of a frame connection 10 in accordance with the present invention and like reference numerals are used to denote like parts. In the embodiment of FIGS. 9 to 12, the first and second elongate members 18 and 20 have the same cross-sectional shape as the first embodiment, however the connection is rotated by 90 degrees, in the first embodiment, the mitred joint between the first and second elongate members 18 and 20 is cut such that the first and second channels 32 and 34 are each on an opposite side of the plane in which the connected elongate members 18 and 20 lie. That is, if the first and second elongate member 18 and 20 were formed into a frame as shown in FIG. 9, the channels 12 and 34 would he on opposite sides of the formed frame assembly. In the embodiment of FIGS. 9 to 12, however, the first channel 32 is on the inside of the frame assembly 12, and the second channel 34 is on the outside of the frame assembly 12.

The connection members 40 of the second embodiment (as shown in FIG. 10) are, therefore, modified in shape. While the first and second portions 42 and 44 are still connected perpendicularly to form an L-shape, the first planar member 43 of the connection member 40 is oriented in a plane perpendicular to that of the second planar member 45. Other features of the connection members 40 remain the same, and the connection members 40 are used to connect together the first and second elongate members 18 and 20 in the same manner as described above.

Also provided are end supports 52 for connecting an elongate member of the frame assembly 12 to a supporting surface, such as a wall or the ground. The end support 52 comprises a base plate 54 and a pair of planar members 56. Each of the planar members 56 are of similar constructions to the first and second planar members 43 and 45 of the connection members 40 in that each include opposed parallel sides 46 having protrusions 48 and a distal end 47. The planar members 56, however, each extend parallel to each other from the base plate 56. The planar members 56 are arranged to be received in the first and second channels 32 and 34 of an elongate member that is to be connected to the supporting surface. The base plate 54 is then connected to the supporting surface by suitable means, such as threaded fasteners.

An end support over plate 58 is also provided to fit over the base plate 56.

The end support cover plate 58 includes an aperture 60 through which the elongate member is received.

FIG. 13 illustrates a third embodiment of a frame connection 10 in accordance with the present invention. The embodiment of FIG. 13 is similar to that of the embodiment of FIG. 9 and like reference numerals are used to denote like parts.

The first and second elongate members 18 and 20 of this type may be used as part of a handrail structure.

FIG. 14 shows a fourth embodiment of a frame connection in accordance with the present invention. The fourth embodiment is similar to the third embodiment in that a connection body 62 is provided to connect the first arid second connection members 40. The connection members 40 however are oriented in the same configuration as the embodiment of FIGS. 1 to 8.

The connection body 62 is provided with a ball joint 64 therein such that the angle between the first ends of the connection members 40 can be adjusted relative to the second ends of the connection members 40. The first and second elongate members 18 and 20 of this embodiment may also be used in a handrail structure in which the angle between the connected rails can be adjusted. Such an arrangement would be suitable for example when the handrail extends upwardly adjacent a staircase.

FIG. 15 shows a fourth embodiment of a frame connection 10 in accordance with the present invention. The embodiment of FIG. 15 is similar to that of the embodiment of FIG. 13 and like reference numerals are used to denote like parts.

In the embodiment of FIG. 15, the first and second connection members 40 are fixed together and a connection body 62 is provided such that the connection body 62 connects a portion of the first connection member 40 between the first and second ends 42 and 43 thereof to the second connection member 40 between the first and second ends 42 and 43 thereof.

The connection body 62, however, is provided with third end portions 45 extending in a direction perpendicular to both the first and second end portions 42 and 44. The first and second end portions 42 and 43 are provided, to connect the first elongate member 18 to the second elongate member 20 in the same manner as the second embodiment. The third end portions 45 are provided to connect to a third elongate member 21. The orientation of the third end portions 45 are such that the connection provided by the first and third end portions 42 and 45 is the same as that of the first embodiment. The first, second and third elongate members 18, 20 and 21 are thereby connected all at right angles to create a corner join of the fencing assembly as can be seen in FIG. 15a.

FIG. 16 shows a fifth embodiment of a frame connection 10 in accordance with the present invention. The embodiment of FIG. 16 is similar to that of the embodiment of FIG. 15 and like reference numerals are used to denote like parts.

In the embodiment of FIG. 16, the connection body 62 is provided with fourth end portions 45 extending parallel to the second end portions 44 but in an opposite direction, The fourth end portions 45 are provided to connect to a fourth elongate member 23.
