    Abstract: An electrical connector of an image forming apparatus exposes outward from a bottom surface of the image forming apparatus. An electrical connector of a sheet feeder protrudes from a top surface of the sheet feeder. The sheet feeder has a slider configured to be horizontally movable, while holding the electrical connector of the sheet feeder, between a connecting position at which the electrical connectors of the sheet feeder and image forming apparatus are connected and a disconnecting position at which the electrical connectors are disconnected. A locking member having a locking engaged part is fixed to the image forming apparatus. When the slider is moved to the connecting position, a locking engaging part of the slider engages the locking engaged part of the locking member so that the locking member and the slider are locked such that they cannot be separated vertically from each other.

  • Patent number: 7866909
    Abstract: The cable locking system is a two-part device that locks a cable-like strap or other flexible or rigid member with an enlarged end into place by using an opposing arrangement of keyhole-shaped apertures bored into two rigid parts. The cable locking system requires no extra hardware to secure the connection, and can be retrofitted to fit virtually any size support system in numerous applications. The cable locking system can be installed quickly and easily without a need for tools, extra labor, or supporting equipment. In the case of a suspension bridge, the suspension parts can be pre-manufactured and assembled, then quickly and easily connected to complete the structure. The cable locking system makes the construction of a suspension bridge or other hoisting device as well as many kinds of structures simple and straightforward, with fewer parts that can potentially fail. The cable locking system can also easily be disassembled.

  • Patent number: 5894641
    Abstract: The object of a snap fastener closure is to couple a male part with a female part (20) as easily as possible, but so that it is difficult to uncouple them. The female part (20) comprises a push plate (30) which is movable longitudinally in a housing (23) and forks into two plate legs in the interior of the housing. The two plate legs are formed of two portions (31, 32) which are profiled differently with respect to the closing head (12) of the male part, one of these portions (31) serving to lock and the other portion (32) serving to release the closing head (12). In order to achieve easy coupling, it is proposed that the portion (31) acting to lock is provided at the free ends of the two plate legs so that they can spread apart elastically. Then, by inserting the closing head (12) of the male part, an automatic coupling in is made possible between the two plate legs. This portion (31) thus becomes the coupling portion.
