Abstract
A mitre joint for a metallic frame of a fenestration unit includes first and second frame members; a connector configured to locate the first and second frame members in relation to one another; and first and second fasteners configured to secure the first and second frame members to the connector. The connector has a first arm configured to extend within a hollow profile defined by the first frame member, and a second arm configured to extend within a hollow profile defined by the second frame member. A longitudinal axis of each of the first and second fasteners is configured to be parallel to a longitudinal axis of the respective connector arm. Each of the first and second fasteners is configured to engage the respective frame member when the respective connector arm extends within said frame member.
Claims17
A mitre joint for a metallic frame of a fenestration unit, the joint comprising:
- first and second frame members;
- a connector configured to locate the first and second frame members in relation to one another;
- and
- first and second fasteners configured to secure the first and second frame members to the connector;
- wherein the connector comprises a first arm configured to extend within a hollow profile defined by the first frame member, and a second arm configured to extend within a hollow profile defined by the second frame member;
- wherein a longitudinal axis of each of the first and second fasteners is configured to be parallel to a longitudinal axis of the respective connector arm;
- wherein each of the first and second fasteners is configured to engage the respective frame member when the respective connector arm extends within said frame member;
- wherein each frame member profile defines at least two projections extending from the profile to engage said fastener;
- wherein each projection of the frame member engages the fastener at an engagement point, and wherein the projections are configured such that the engagement points are equidistant about a periphery of the fastener;
- and
- wherein each connector arm defines a support for each projection, each support being configured to contact said projection when the connector arm extends within the respective frame member.
A connector for connecting first and second frame members to form a mitre joint wherein the connector comprises a first arm configured to extend within a hollow profile defined by the first frame member, and a second arm configured to extend within a hollow profile defined by the second frame member;
- and
- first and second fasteners configured to secure the first and second frame members to the connector;
- wherein a longitudinal axis of each of the first and second fasteners is configured to be parallel to a longitudinal axis of the respective connector arm;
- wherein each of the first and second fasteners is configured to engage the respective frame member when the respective connector arm extends within said frame member;
- wherein the first and second fasteners are each configured for engagement with the hollow profiles of the first and second frame members at engagement points, the hollow profiles each defining at least two projections extending from the hollow profile to engage with the respective fastener;
- wherein the first and second fasteners are each configured to extend into the hollow profiles such that the engagement points are equidistant about a periphery of the fastener;
- and
- wherein each connector arm defines a support for each projection, each support being configured to contact said projection when the connector arm extends within the respective frame member.
A mitre joint for a metallic frame of a fenestration unit, the mitre joint comprising:
- first and second frame members;
- a connector configured to locate the first and second frame members in relation to one another;
- and
- first and second fasteners configured to secure the first and second frame members to the connector;
- wherein the connector comprises a first arm configured to extend within a hollow profile defined by the first frame member, and a second arm configured to extend within a hollow profile defined by the second frame member;
- wherein a longitudinal axis of each of the first and second fasteners is configured to be parallel to a longitudinal axis of the respective connector arm;
- wherein each of the first and second fasteners is configured to engage the respective frame member when the respective connector arm extends within said respective frame member;
- wherein each fastener is confined in both axial directions such that the connector can be pushed out by the fastener during disassembly and/or adjustment;
- and
- wherein each connector arm defines a support for each projection, each support being configured to contact said projection when the connector arm extends within the respective frame member.
