| 20110114779 | POWER FEEDING DEVICE AND WIRE HARNESS ARRANGING STRUCTURE USING THE SAME - In a power feeding device which absorbs a surplus length by enlarging or reducing spirally the diameter of a flat wire harness, a wire harness surplus length absorbing performance is improved, a structure is simplified and a cost is decreased. A power feeding device | 05-19-2011 |
| 20110186675 | WEBBING TAKE-UP DEVICE - A webbing take-up device with a small difference in a frictional force between an outermost layer portion of a spiral spring along a circumferential direction of a rotating body and an inner peripheral portion of the rotating body is obtained. A reduction sliding spring is formed in a curved shape, such that the radius of curvature becomes gradually larger in a predetermined ratio toward a longitudinal central portion from both longitudinal ends in a state where the reduction sliding spring has not been elastically deformed in a circular shape. The amount of elastic deformation accompanying a minute change in a position from the longitudinal central portion to both longitudinal ends becomes approximately equal in a state where the reduction sliding spring has been elastically deformed in the circular shape. Therefore, a radially outward elastic force having substantially a center of the reduction sliding spring as its center becomes approximately equal. | 08-04-2011 |
| 20120061502 | LIMITING MECHANISM FOR LIFTING AND LOWERING BLIND - The present invention relates to a limiting mechanism for lifting and lowering a blind. The limiting mechanism includes a carrier; a resilient unit movably disposed at an end of the carrier; a recoiling roller movably disposed in the carrier and positioned proximate to the resilient unit; and a tractional unit movably disposed in the carrier and driven by the recoiling roller. The limiting mechanism is integrated into a blind body when in use, so as for a shade to be lifted or lowered when an external force is exerted thereon by a user, wherein the lifting or lowering of the shade is effectuated by the resilient unit, the recoiling roller, and the tractional unit in conjunction with the external force exerted by the user, so as to dispense with a tractional cord and enhance ease of use and use safety. | 03-15-2012 |
| 20140084098 | WEBBING TAKE-UP DEVICE - A webbing take-up device is obtained that is capable of reducing the load on a reduction balance spring without using special components, and without performing special processing on a spiral direction inside end of the reduction balance spring. When the reduction balance spring rotates in a take-up direction as winding of the reduction balance spring loosens, an inside engagement portion turns in the take-up direction inside an engagement groove. Accordingly, a load absorption portion which is further to a main body portion side of the reduction balance spring than the inside engagement portion curves into a concave shape that is open towards a pull-out direction as the load absorption portion stands up. In this state, when further load in the take-up direction acts on the reduction balance spring, this load is absorbed by the load absorption portion undergoing resilient deformation so as to curve further. | 03-27-2014 |
| 20140291431 | CORD-WINDING DEVICE FOR A VENETIAN BLIND - A cord-winding device for a Venetian blind includes: a first reel; a driving unit including a driving wheel and a spring-winding wheel; and a brake unit including a driven gear, a driving member, a ratchet wheel sleeved on the driving member, a plurality of friction members disposed between the driving member and the ratchet wheel, and at least pawl biased to engage the ratchet wheel. When the driven gear is driven by the first reel to rotate in a direction, rotation of the ratchet wheel is stopped by the pawl so that the driving member drives the friction members to rotate, and when the driven gear is driven by the driving wheel to rotate in an opposite direction, the driving member drives rotation of the friction members and, thus, the ratchet wheel. | 10-02-2014 |
| 20150008273 | SPRING-DRIVEN REEL - A spring-driven reel is adapted to include a gear assembly, and a reel assembly operatively coupled to at least one gear of the gear assembly. The spring-driven reel can also include at least one spring assembly. The spring assembly can include a screw member and a non-rotatable nut moveably mounted to the screw member. | 01-08-2015 |
| 20150034752 | DUAL SELF-WINDING RETRACTABLE DEVICE FOR A WIRE OF A HEADPHONE - The object of invention is a dual self-winding retractable device for headphone cords, designed in particular for thinner, more delicate cords, and especially adapted for cords of mobile phone headsets, cords of iPod headphones, etc. As invented, the dual self-winding retractable device has two independently moving winding reels ( | 02-05-2015 |
| 20150367814 | Safety Belt Retractor With a Two-Spring Comfort Function - The invention relates to a safety belt retractor that has a two-spring comfort function, a belt shaft which is rotatably mounted in a housing and on which a safety belt can be wound, and at least two return springs that are spring-loaded in the winding direction of the belt and act between the housing and the belt shaft. The return springs being able to be connect by one end to the belt shaft or the housing by means of a shift device that shifts as a function of the extraction length of the safety belt. | 12-24-2015 |
