  • Patent number: 7654430
    Abstract: A coil nailing device for finishing materials is invented that comprises a standby part for temporarily retaining and loading the nails into a muzzle. A door is installed adjacent to the standby part to check the nail supply. A door latch consists of a hook, coil spring and latch hinge shaft. The door and door latch are operated in the lateral direction, perpendicular to the axis of the main body. The muzzle consists of an adapter, lever arm and a pair of arc-shaped sliding grooves formed on both lateral surfaces. The adapter is attachable to the nose of the main body. A clearance setting device is designed to allow the use of various sizes of nails by setting the depth of the magazine depending on the loaded nail size. An interval setting device is convenient to nail a series of shingle panels by setting the panel interval while the coil nailing device is sliding along the edge of the panels.

  • Publication number: 20090156275
    Abstract: A semi-automatically sliding mobile terminal is disclosed. The mobile terminal includes a first main body, a second main body, a hinge unit, and a guide line. The second main body slides on the upper side of the first main body. The hinge unit includes a coupler coupled to the first main body and a spring unit compressing and expanding in a lateral direction. The guide unit includes a curved line having an ascending curved line, a crest, and a descending curved line that are formed in a longitudinal direction. When the second main body moves, the spring unit compresses or expands along the guide line. The spring unit compresses before passing over the crest and expands after passing over the crest. After the crest, the second main body moves semi-automatically due to elastic force of the spring unit.

  • Publication number: 20070251073
    Abstract: An apparatus and method for changing a spatula blade is provided. The apparatus has a restraining element for engaging the blade to restrain the blade on a blade support surface. A restraining member is movable from a first position spaced from the blade support surface, and a second position for limiting movement of the blade while restrained by the restraining element at the blade support surface. To remove a blade from a spatula body, the restraining member is moved to the second position. In the second position, movement of the blade is limited to prevent disengagement from the restraining element. A force is applied to the spatula body to separate the body from the blade. To install a blade to a spatula body, the blade is restrained by the restraining element and the restraining member and the spatula body is advanced toward the blade to mount the blade to the body.

  • Publication number: 20060237512
    Abstract: A nail retainer for a tacker comprises a guider receiving nails transmitted from a magazine, guiding the nails received therein, and comprising a hole formed through a designated portion of the upper surface thereof; and a stopper axially connected to the hole of the guider, moving together with the movement of a contact arm to prevent the nails received in the guider from dropping when the contact arm moves forward, and releasing a nail-stopping motion for preventing the nails from dropping when the contact arm moves backward. The nail retainer does not cause failure due to the attraction of iron filings remaining in a magazine or a guider onto the surface of the member, differing from conventional nail retainers made of a magnetic material, and moves together with the movement of a contact arm to reliably prevent a nail from dropping, thereby increasing the consumer's reliability.

  • Patent number: 7013837
    Abstract: A pig pen structure has a walking passage and a plurality of pig houses for housing an animal installed along the walking passage. Each pig house has an evacuation room, a lodging room having front, back, and two side walls, and an evacuation room gate installed between the evacuation room and the lodging room. The evacuation room is accessible to the animal for excretion when the evacuation room gate is opened. The evacuation room gate when closed becomes a part of the back wall. A urine tube is installed on the bottom of the evacuation room, so that the excreted urine in the evacuation room flows down to the urine tube to remove the excreted urine outside the pig house. The plurality of the pig houses is arranged so that the front walls of the pig houses adjoin the walking passage. A continuous passage way is formed by the evacuation rooms along the back wall of the lodging room when the evacuation room gates of the pig houses are in closed position.

  • Publication number: 20040069239
    Abstract: A method for building an environment-affinitive pigpen and a pigpen structure is provided. A structure of a pig house in a pigpen is divided into an evacuation room, a lodging room, and a feed bucket. Urine excreted in the evacuation room is moved into a container for urine located out of the pigpen, and remaining excrements are separately collected from the urine, to thereby prevent pollution of the pig house and prevent offensive odor and the propagation of various bacteria and vermin, and to thus constitute comfortable and sanitary breeding circumstances. A power cable is installed on a partitioning pipe in the pig house, horizontally with respect to the pipe, to thereby build the height of the pig house at a low position, and to thus widen a field of vision in the pigpen. Also, the partitioning pipe can be installed horizontally to thereby make a convenient workability and save a cost for building a pigpen, and provide sanitary and comfortable breeding circumstances.
