| 20130036846 | MOBILE ELECTRONIC DEVICE HAVING MEMBER ROTATABLE BETWEEN FIRST AND SECOND POSITIONS - According to some embodiments, a mobile electronic device is provided with a linkage mechanism that couples first and second members of the device such that the device may be moved between a first position and a second position. The linkage mechanism includes a linkage intermediate the first and second members, the linkage having a fixed length. The linkage mechanism further includes a motion constraint mechanism that constrains movement of the first member with respect to the second member to a controlled motion. The linkage mechanism described herein may further provide that the top member rotates without increasing the length or width of the device. | 02-14-2013 |
| 20130139619 | Continuously variable transmission - A continuously variable transmission includes: an input movement, a control system, a continuously variable reciprocating movement, a first holder, a second holder, a chain, an output sprocket, and a freely rotatable sprocket. The holders having the reciprocating movement. Each of the holders having a linearly movable teeth. The movable teeth are perpendicularly movable to the reciprocating movement. Each of the movable teeth having an internal end and an exposed end. The exposed end having a first slope and a second slope. The first slope having a greater slope than the second slope. | 06-06-2013 |
| 20130152714 | SEAL STRUCTURE - An object of the present invention is to provide a seal structure being capable of preventing rain water and the like from entering the inside of a vehicle through a clearance between an engagement portion and an engagement hole portion. The seal structure S is for fixing a window regulator WR to an inner panel | 06-20-2013 |
| 20130205928 | Reciprocating Lever Transmission - A reciprocating pedal transmission for a pedal-powered vehicle. Two pedals are selectively connected to a driveshaft by one way clutches. A reversing gear mechanism forces the non-pushing pedal to travel in a direction which is opposite to the direction of the pushing pedal. The non-pushing pedal may also be used to input force (a pulling force) if desired. The arcuate range of motion is infinitely variable. The user may reverse the pedal travel at any time using only the forces applied by the feet. | 08-15-2013 |
| 20130305852 | ROLLER MAINTAINING CHAIN AND METHOD FOR MAKING ROLLER MAINTAINING CHAIN AND LINEAR MOVEMENT DEVICE - A roller maintaining chain includes an elongate strip having multiple holes separated by separation blocks. Each hole has a hole face perpendicular to the elongate strip. Each separation block has a top separation block and a bottom separation block. Each of the top and bottom separation blocks has an accommodating surface which has a flat surface and an inclined stop surface. A part of each accommodating surface is perpendicular to planes on the axial direction of the elongate strip. The flat surfaces of the top and bottom separation blocks are smoothly connected to each other. The inclined stop surfaces are inclined toward the top direction of the holes to maintain the rollers in the holes. The method for making the roller maintaining chain uses a left mold and a right mold, the two molds are split inclinedly and laterally to obtain the roller maintaining chain. | 11-21-2013 |
| 20140123784 | STACKING MACHINE - The present invention relates to a stacking machine, which comprises a base, a body movably arranged on the base, and a translational mechanism for driving the body to make a translational motion on the base. The synchronous belt used in the present invention can effectively resolve the problem of slipping caused by wheel rolling, and thus enables the movement of the stacking machine to be more accurate, with the highest speed of the movement also increased significantly. Besides that, the synchronous belt mechanism is more accurate in positioning, which reduces the number of times of repeated adjustments and maintenance caused by bigger positioning errors. | 05-08-2014 |
| 20140190285 | Oscillatingly Driven Power Tools With Toothed Belt Drive - The invention discloses an oscillatingly driven power tool, having a motor shaft that can be driven rotationally by a motor and that is coupled via a toothed-belt drive and an eccentric coupling drive to a tool spindle, for the purpose of driving the latter. | 07-10-2014 |
| 20140238162 | SPEED REDUCER - This invention refers to a speed reducer made up of a chain carrying nuts and of a screw, i.e., a ball screw in the case of the first embodiment, a roller screw in the second embodiment. The ball screw or the roller screw drives the nuts when these are aligned on one of the straight stretches of the chain. The ball screw, or the roller screw, can be almost as long as the distance between the centers of the output sprockets on which the chain is mounted; given these features and because the nuts wrap the ball screw, or the roller screw in a great surface, the load capacity is high. Given that in both embodiments the contact is rolling, friction is therefore low and as a consequence, efficiency is high, so high indeed that it allows this invention also to serve as an amplifier. | 08-28-2014 |
| 20150020620 | SIX-DEGREE-OF-FREEDOM CAM-CONTROLLED SUPPORT PLATFORM - A platform is provided, which platform is adapted to engage a base through a multiplicity of pulley engaging cables. A first end of each cable is attached to a cam follower assembly located on the base and a second portion of the cable is attached to the platform. A motor driving the multiplicity of cams, cam followers, and cables will move the platform, the platform typically being suspended above the base on the cables or the cables and compression springs. | 01-22-2015 |
| 20150330485 | APPARATUS FOR DRIVING LINKS - An apparatus for driving links is provided and includes a base onto which an actuator is installed and a plurality of connection links connected to the base via a plurality of hinge pins, and the respective end of which is connected via the hinge pin to form a series of a driving lines. A plurality of capstans are disposed on the plurality of hinge pins, respectively and a wire allows the respective capstan to be rotated when the actuator drives by sequentially connecting the actuator and the respective capstans. A plurality of clutches are disposed on the plurality of hinge pins, respectively, and allow the connection links and the capstans to be rotated together, or allow the capstans to be rotated by connecting or disconnecting the ends of the connection links and the capstans, respectively. | 11-19-2015 |
