摘要： A light bulb changing device with expandable fingers is extendable to allow a person to install and remove light bulbs from an elevated ceiling without need for climbing a ladder. The device includes a tube, with the fingers attached thereto. A horn is slidably disposed on the top, movement of the horn adjusts the movement of the fingers. A compression spring and pulley housing with pulleys therein actuate movement of a tension member allowing for opening of the fingers and closing the fingers around a light bulb with limited torque to avoid breaking the light bulb.

摘要： A light bulb changing device with expandable fingers which can grasp all light bulbs within a size range between 1 inch and 6 inches diameter and all shapes of light bulbs including incandescent, compact fluorescent and LED having a screw thread base. The disclosed device is extendable to allow a person to install and remove light bulbs from an elevated ceiling without need for climbing a ladder. The device provides for a user to controllably expand the fingers to insert or remove a bulb at both the proximal (bottom)and distal (Ceiling) ends of the device so that a user can reach up to the ceiling, open the fingers to grasp the bulb using the proximal actuation, remove it, bring it down to reachable level, remove the used bulb using the distal actuation, insert a new bulb using the distal actuation, elevate the bulb to the ceiling screw it into the socket and using the proximal actuation open the fingers to complete the job. The disclosed device controls the torque with which the fingers grasp the bulb to prevent separation of the glass bulb from the metal base.

摘要： A barrier system includes at least first and second reinforced concrete posts, each concrete post including at least one conduit formed therethrough having first and second ends and a strain relief sector formed therein at the first end of the conduit. At least one tension cable extends between the posts. The tension cable extends through the conduit of each post and has a cable end secured to the post at the second end of each post's conduit.
