20090158552 | FLIP-TYPE ELECTRONIC APPARATUS - A flip-type electronic apparatus includes a base panel, a cover, and a latch mechanism pivotably fastening the cover to the base panel. At least one post extends from the cover into the base panel. The latch mechanism includes a button mounted on the base panel, and a sliding bar received in the base panel. At least one limiting portion is formed on one lateral side of the sliding bar receiving the post of the cover. The sliding bar forms a pair of inclined operating surfaces, and the button forms at least one inclined actuating surface abutting at least one of the pair of inclined operating surface. When the button is pressed, the actuating surfaces pushes the operating surfaces to cause the sliding bar to move away from the button, and thus the post is released from the limiting portion for opening the cover of the electronic apparatus. | 06-25-2009 |
20100101046 | PIVOTING CONTROL DEVICE FOR PIVOTING BODY - A rotation control device is configured so that a spring force of a torsion coil spring holds an attitude of a rotation body at a pre-advancement position corresponding to a post-return position (a), and a post-advancement position corresponding to a pre-return position (b), respectively. The rotation control device includes a first rotation part supporting one end of the torsion coil spring and supported on a fixed body so as to rotate as the rotation body rotates, and a second rotation part rotatably supported on the fixed body at a first rotation part side and supporting the other end of the torsion coil spring. When the first rotation part rotates, the second rotation part rotates together with the first rotation part. A wound portion of the torsion coil spring is most elastically deformed when the rotation body is at an intermediate position (c) between the position (a) and the position (b). | 04-29-2010 |

The invention has the following benefits: 1) the pull rod can be limited and positioned at any angle through the self-control positioning mechanism, thereby ensuring that a door leaf can be positioned arbitrarily and facilitating personnel circulation or cargo transportation and the like; and 2) the overall structure is reasonable and compact, the operation is convenient and easy, and the door closer is safe, practical and reliable, and further applicable to popularization and use in different occasions. | 07-05-2012 |
20130205540 | HINGE DEVICE - A hinge device in which a slider elastically supported by a compressive coil spring is put into contact with a pivotal lever installed on a cover of a product which swings open or closed. The hinge device can increase a free stop section and simultaneously prevent the cover from being incidentally open. | 08-15-2013 |
20150040347 | Door Closure - The door closure employs a pivotally mounted roller assembly to engage a roller within a recess of a mounting hook. The roller assembly also has a pair of leaf springs that are used in tandem to passively retain the bracket in each of the open position and the closed position. | 02-12-2015 |
20150052705 | SLAM LATCH BOLT DAMPENER - A slam latch mechanism employs an actuation lever rotatable from a first position to a second position and having a prong extending therefrom. A bolt, resiliently retractable from an extended position with the actuation lever in the first position, has a land with a slip surface engaging the prong in the second position to retract said bolt. A dampener extends from the slip surface by a margin to engage said prong in the first position to prevent metal to metal contact by the prong and slip surface with the actuation lever in the first position. | 02-26-2015 |
20150300068 | DEVICE FOR OPENING AND CLOSING SLIDING DOOR - Provided is a device for opening and closing a sliding door, of which collinearly placed doors slide respectively to overlap each other such that the sliding door is opened or closed. The device includes a sliding portion formed on a surface on which doors come into contact with each other in order to prevent the doors from interfering with each other when the doors are opened; a pair of rail frames formed on a top surface of the furniture and provided with a rail protruding upwardly such that each door is slid forward and backward on the rail, the rail having both sides in which bending portions are formed; and rotational members, each of which is installed to one side of a connection bracket to be rotatable in a curved section of the bending portion while being lifted and slid on the rail. | 10-22-2015 |
20150330128 | HINGE WITH LARGE OPEN-CLOSE ANGLE FOR FUNITURE DOOR - A hinge with large open-close angle for furniture door includes a retaining bracket connected to wallboard, a sliding seat connected to the door and a hinge module connected with the retaining bracket and the sliding seat. The hinge module includes a fixed arm, a link arm, the first turning arm, the second turning arm and the third turning arm hinged successively. Whereby, one end of the first turning arm with salient point or bend is hinged with the retaining bracket. The said retaining bracket is installed with damper and rocking block. The damper has reset spring, while the rocking block has the first and the second acting surface. In the process of hinge closing, the first acting surface aims to coordinate with the salient point or bend on the first turning arm, while the second acting surface is coordinated with the damper. | 11-19-2015 |
