  • Patent number: 11945079
    Abstract: A screwdriver includes a main body and a switch. The main body is coupled to a handle and includes a pair of parallel, spaced apart slots, and a pawl positioned in each slot. Each pawl is biased outwardly by a spring. The switch is pivotable relative to the main body, and the switch includes a groove extending along an arcuate portion of an inner surface. Pivoting the switch in a first direction moves the switch toward a first position in which the groove is positioned in-line with the first pawl. When the switch is in the first position, the first pawl extends outwardly from the slot and engages the internal tooth surface such that application of a torque in a first direction drives a shank in the first direction and application of a torque in the second direction causes the shank to ratchet relative to the main body.

  • Patent number: 8925361
    Abstract: A door having a latch mechanism is provided. The door also includes a bracket, and a pawl having a first aperture. The pawl is rotatably attached to the bracket and is operatively connected to the latch. The door additionally includes a key-cylinder adapted to selectively lock and unlock the latch by rotating the pawl, and a shield having a second aperture. Furthermore, the door includes a component connected to the key-cylinder. The component is aligned with and extends through the first and second apertures without contact with the pawl or with the shield, and is configured to not impede the rotation of the pawl by the key-cylinder when the component is aligned with the first and second apertures. The component is also configured to detach the pawl from the bracket and limit the key-cylinder extraction, when the key-cylinder is forcibly manipulated thereby causing the component to contact the shield.

  • Patent number: 8833122
    Abstract: A transport clip for attachment to a key fob is provided. The transport clip includes a neck at least partially surrounding a key blade, which is selectively rotatable between a stowed position in which the key blade is substantially within a fob body and a deployed position in which the key blade extends away from the fob body. The neck prevents rotation of the transport clip relative to the key blade. The transport clip also includes an ear portion that depresses a latch button to an unlocked position, which allows substantially free rotation of the key blade, relative to the fob body, between the deployed position and the stowed position.

  • Patent number: 5296663
    Abstract: The present invention is an electric switch for switching individual phases of multi-phase AC electric power. The switch has at least one pair of fixed terminals with each terminal of the pair having an ear extending upward in a vertical plane. The switch also has a conducting device with contacts that extend downward in the vertical plane corresponding to the fixed terminals. Moving contacts are mounted to an axially translatable contact carrier and engage contemporaneously in the vertical plane with the contacts from the conducting device and the fixed terminals when the contact carrier slides into an "on" position. Electrical power is then able to flow from the line-side fixed terminal, through the conducting device, to the load-side terminal. The contact carrier is translated axially by the drive mechanism. The drive mechanism employs over-center shifting and lost-motion switching technology to prevent the switch from being in a partially "on" position.

  • Patent number: 4395606
    Abstract: A manually operable, three-pole disconnect switch has a contact structure for each pole that comprises a line-side contact module and a load-side contact module that carry the stationary contacts for that pole, these contacts being vertically spaced and positioned for engagement by one of three movable contact assemblies carried on a horizontally disposed, pivotable crossbar. Each line-side contact module extends upwardly from the crossbar and each load-side contact module extends downwardly from the crossbar and its corresponding line-side contact module. The line-side contact module has two integrally formed housing parts and a bar-shaped conductor that is sandwiched therebetween and positioned in a substantially vertical plane. The housing forms both an insulating base and an insulating portion of an arc chute which partially encloses the conductor that forms a stationary contact within a housing cavity.
