Definitions

the present invention relates to a connector, preferably of thin sheet metal, and in particular to a connector for the concealed joining of a first component such as a beam or a post to a second component made of wood or another material.
the present invention also relates to a connection formed using the connector, and to a method forming a connection using the connector.
the connector according to the present invention has particular utility as a concealed beam attachment or a post foot, and comprises a planar attachment web provided with through holes which is to be received in a slot, generally in the end surface of the first, typically wooden, component to be attached.
the planar attachment web is also provided with, or is capable of having formed in it, one or more apertures dimensioned to receive the head of fasteners protruding from the second element.
the connector is first fastened to the second component, and then fastened to or configured to hold the first component with fasteners such as dowels or the like which, in use, extend through the through holes of the connector.
the connector further comprises one or more fastening flanges which, in use, are generally bent 90 degrees out of the plane of the attachment web and configured integrally with the attachment web.
the fastening flange or flanges comprise one or more slots dimensioned to receive the shank of the one or more fasteners protruding from the second component, so as to permit rotation or twist of the connector from a first connector insertion position where the shank of each fastener protruding from the second component passes through a slot and is out of the plane of the attachment web to a second connector located position where the shank of each fastener protruding from the second component passes through a slot and is in of the plane of the attachment web.
a concealed joint is understood to be a joint in which the first timber component (or “joining element") is at least substantially surrounded by other timber components.
the slot is configured not as a continuous slot but as a "blind slot” in order to weaken the first timber component as little as possible and to prevent the slot from being visible after assembly.
available for this purpose are "keyway cutters”.
continuous slots are cut, generally with a circular saw, into the end surface of a beam.
Connectors known in the art are generally no more than 1 mm less than the slot width in which they are to be received in order to prevent the attachment web from "wobbling" in the slot. Accordingly, the sheet thickness of such connectors has previously been up to at least 6 mm. This gives rise to a requirement for an unnecessary use of raw material, and it is also known that thicker sheets are more difficult and complex to work. It is therefore desirable to reduce significantly the material thickness of the type of connectors under discussion here, and embody them, for example, with a sheet thickness of only up to 3 mm. However, in turn, this limits the load capacity of known connectors and can complicate the assembly and number of parts required to achieve the connection.
DE 9001067 discloses a connector formed from a thin sheet approximately 3 mm thick, and provides its attachment web with formed embossment knobs or beads whose height is substantially equal to the slot width of the first timber component being attached.
the fasteners in the second component can be aligned in the plane of the attachment web, but to achieve this requires a significant number of parts. This makes the connector cumbersome and requires manual dexterity and accuracy for an installation to achieve its design load capacity. However, incorrect installation of one or more of the parts can result in significant reduction of load capacity.
the present invention addresses these known limitations of prior art connectors.
the present invention is a one-piece connector, made in particular of thin sheet metal, in which the disadvantageous effects described above do not occur even under extreme stresses that lie within the allowable range.
the present invention to provides a joining element which is suitable not only as a fitting for concealed attachment of a beam, but also as a post foot.
