  • Patent number: 9550082
    Abstract: A forcible entry training simulator. The simulator has a clamping structure that allows for hinges to be affixed and cut by a trainee in the same manner as would have to be accomplished for forcible entry into a building. The simulator has plunge-cutting and lock-pulling simulators as well. In addition, the simulator has a stabilizing wheel structure utilized to allow easy transport and handling of the simulator. The structure of the simulator allows low cost alternatives to materials to be used to provide the same level of training as though actual hinges, doors, and locks were being utilized, but without the significant expense of utilizing actual real-world materials in training where the materials will, of necessity, be destroyed.

  • Patent number: 8360489
    Abstract: A cylindrical lever lock using a lever as a handle for convenient use by even the disabled and the old is disclosed. Since plate shafts, spring holders and spring cage covers constituting the cylindrical lever lock are made of general metal plates, the material cost and the prime cost may be reduced. In addition, the spring holders are connected through double engagements with spring cages and the spring cage covers. Therefore, deformation of parts or drooping of levers may be prevented in spite of an excessive force applied. Furthermore, assembling and disassembling of the parts can be quickly and easily performed by achieving adjustment of intervals of the parts according to thickness of a door using a female screw of an outer attachment plate and a male screw of a boy assembly.

Two positioning posts extend from an outside rose liner mounted around the outside seat. Two fasteners extend through the reinforcing ring and the inside rose liner into screw holes of the positioning posts, thereby securing the reinforcing ring, the inside rose liner, and the outside rose liner together. The torque-resisting capacity is thus improved.

  • Patent number: 6880872
    Abstract: A lever handle return spring assembly for a cylindrical lock mounted in a bored opening in a door includes support plates on opposite sides of the door. The support plates include cylindrically depressed inner regions that extend partially into the bored opening in the door to accommodate return springs and reduce the visual thickness of the return spring assembly. Spring housings containing compression springs turn within the support plate inner regions and are held in place by cover plates. The support plate, cover plate, spring housing and springs on each side of the door form complete assemblies that are attached to the door via through-bolts. At least one of the support plates preferably includes lock tabs that connect to the cylindrical lock to prevent rotation of the cylindrical lock relative to the door. The support plate and cover plate are designed for strength when stamped from a flat sheet.
