  • Patent number: 8079398
    Abstract: A blind is provided which uses a toothed band bodies such as slender toothed belts as rod holding bodies including operating band bodies, instead of conventional cords and tape, having a straightforward structure providing accurate and stable parallel holding of moving rods, and quit and smooth movement, due to accurate operations without slippage due to engaging of bands and wheels having teeth, without problems such as tangling and bending and the like. Particularly, a rod movement holding device suitable for having multiple moving rods and having multiple shielding adjustment faces, and a blind having a rod operating device, can be provided.

  • Patent number: 8038189
    Abstract: In a tool for picking up and carrying dog dung that includes a container longitudinally swingably supported at the tip of a shaft part and a cover placed on the container to swing in a direction opposing the container. When an opening part of the container is covered with the cover, the container is upward positioned roughly perpendicularly to the shaft part When the dung is discharged, the container and the cover are opened to incline on one side of the shaft part, so that a tool washable by brushing because of the small number of support and operation members existing around the container. A shaft includes one shaft supporting unit at one end of the shaft part, the shaft supporting unit having a swing axis parallel to a cover swing axis. The container is longitudinally swingably supported so that its container supported part formed on one side of the rear outer wall near the opening part and having the same axis as the cover swing axis is supported on the shaft supporting unit.

    Abstract: A blind is provided which uses a toothed band bodies such as slender toothed belts as rod holding bodies including operating band bodies, instead of conventional cords and tape, having a straightforward structure providing accurate and stable parallel holding of moving rods, and quit and smooth movement, due to accurate operations without slippage due to meshing of bands and wheels having teeth, without problems such as tangling and bending and the like. Particularly, a rod movement holding device suitable for having multiple moving rods and having multiple shielding adjustment faces, and a blind having a rod operating device, can be provided.

  • Patent number: 7735886
    Abstract: A tool for picking up and carrying dog dung excellent in appearance and capable of being easily carried in dog walk. The tool being is operable on hand in catching, carrying, and discharging the dog dung. At least one swinging support is provided at an end of a long shaft extending from a grip of a shank. A receiver and a lid swinging in directions opposing each other are provided with openings and peripherals supported by the swinging support. Bosses formed on parts of outer walls of the receiver and the lid are connected to operating rod vertically movable along the shaft via link. By an operation unit of the operating rod arranged adjacent to the grip, the receiver is upturned about at the right angle to the shaft when the lid is shut. The receiver and the lid are largely opened forwardly during discharge of the dung. At an intermediate opening position, the receiver is inclined in a direction suitable for catching the dung by the receiver.

  • Patent number: 7544083
    Abstract: An object is to provide an electric plug that can be pulled out silently and easily with one hand even from a power socket not secured without requiring any special device in or around a plug body. A front surface part and a back surface part to which the first finger and the second finger, respectively, of a gripping hand gripping the plug body are applied are provided on a forward end side of the plug body. A grip part for the third and subsequent fingers provided with a grip-shift stopper arranged at a part between a rear end of the front and back surface parts of the plug body and a position at a distance of about a four-finger width of the hand from the forward end of the plug body is provided. The electric plug can be pulled out from the socket by applying the first and second fingers of the gripping hand to the forward end side of the plug body, holding the grip part with the third and subsequent fingers, and then pushing the upper surface of the socket with the tip of the first finger.

  • Patent number: 4920614
    Abstract: A clamping device which has clamping units including a pair of openable arms extending in a V-shape toward one side of a pivotal center and in a X-shape toward both sides thereof, and a pair of retainers projecting from the ends of each of the arms a predetermined length toward the end, and a clamping means slidably engaged with parts of the arms of said clamping units for adjusting and holding the amount of closing of the arms in response to the thickness of an article to be clamped. The article is clamped and held by the force of restoration produced by the deformation of the clamping units occurring when the article is inserted between the pair of retainers and the pair of arms are closed.
