  • Patent number: 12337499
    Abstract: A miter saw has a base having a detent notch, a table rotatably connectable to the base, a pivoting assembly connected to the table, and a saw assembly supported by the pivoting assembly. The saw assembly has a blade movable downwardly for a cutting operation. A locking mechanism is disposed on the table. The locking mechanism is movable between an unlocked position and a locked position for selectively unlocking and locking the table for rotational movement relative to the base about the miter axis. The locking mechanism has a lock lever rotatably connected to the table. The lock lever has a handle for moving locking mechanism between the locked and unlocked positions. The saw also has a miter detent assembly for selectively engaging and disengaging the detent notch.

  • Publication number: 20250067067
    Abstract: The present disclosure describes a platform assembly for a monopole. The platform assembly includes a plurality of T-arm assemblies. Each T-arm assembly has a platform frame including a pair of support members, a pair of brace members coupled to and extending between the pair of support members, at least two grating edge members coupled to the support members, and a pair of gratings, each grating coupled to a grating edge member and one of the brace members such that the pair of gratings are separated to define an opening therebetween. Each T-arm assembly further includes an adjustable arm member configured to move relative to the support members and a pair of locking mechanisms, each locking mechanism coupled to a respective support member and configured to secure the adjustable arm member in a desired position in relation to the platform frame. Other platform assemblies and related antenna assemblies are described herein.
