Howmet Aerospace has been granted a patent for a framed assembly that includes a corner cleat connecting two frame members. The corner cleat has a passageway that allows communication between the inner channels of the frame members. The patent also mentions that at least one of the apertures in the corner cleat has a larger diameter than the passageway, providing a sloped transition. The cross-sectional size of the passageway remains constant throughout. GlobalData’s report on Howmet Aerospace gives a 360-degree view of the company including its patenting strategy.

Patent granted for a framed assembly with corner cleat
A recently granted patent (Publication Number: US11773646B2) describes a framed assembly with a unique corner joint design. The assembly includes a first frame member and a second frame member positioned adjacent to each other at a corner joint. A corner cleat is used to connect the two frame members, with a first leg of the cleat engaging the first inner channel of the first frame member and a second leg engaging the second inner channel of the second frame member. The corner cleat has a passageway that allows communication between the first and second inner channels, with apertures at each end of the passageway. The apertures have a larger diameter than the passageway and provide a sloped transition between the legs and the passageway. The cross-sectional size of the passageway remains constant between the apertures.
The patent also describes a method of assembling the corner joint of the framed assembly. The method involves extending the legs of the corner cleat into the inner channels of the frame members and advancing the frame members towards each other to form a seam. Wiring can be positioned within the passageway of the corner cleat, extending into the inner channels. The wiring can be inserted into the passageway before or after extending the legs into the inner channels. In one embodiment, the passageway provides an opening on the lateral side of the corner cleat, allowing lateral insertion of the wiring.
The corner cleat itself is also a subject of the patent. It consists of an angled body with a first leg and a second leg, as well as a passageway inside the body. The passageway terminates at apertures at each end of the body, allowing access into the passageway. Similar to the framed assembly, the apertures have a larger diameter than the passageway and provide a sloped transition between the body and the passageway. The passageway can be defined through the center of the body or provide an opening on the lateral side.
Overall, this patented framed assembly and corner cleat design provide a unique solution for connecting frame members at corner joints, allowing for easy wiring installation and a secure connection.
