Abstract:
The present invention provides a two-way clutch assembly for a rotor operating device which is safe and quiet, does not use a lubricant to increase durability, is applicable regardless of various loads, and does not use a wrap spring. The two-way clutch assembly includes a two-way driver (710) having a two-way movement groove which is formed on the inner circumferential surface of a body and has a small diameter part (710c) and a large diameter part (710d); a wheel retainer (720) which has resilient member holders (720a) radially arranged on a body and is connected to an operating member to be able to rotate; a roller member (730) inserted between the two-way movement groove of the two-way driver (710) and the unit resilient member holders (720a) of the wheel retainer (720) to be able to rotate; and an insertion member which is connected with the wheel retainer (720) via a bushing and selectively gets in contact with the roller member (730) or is released from the contact with the roller member. In the case that the two-way driver (710) is not rotated through the wheel retainer (720) but tries to rotate autonomously, the roller member (730) gets in contact with the insertion body and is rotated and connected with the insertion body while being pressed by the small diameter part (710c). When the wheel retainer (720) is operated, the roller member (730) which is locked by the resilient member holders (720a) is revolved and is resiliently supported, and then, pushes the small diameter part (710c) of the two-way movement groove of the two-way driver (710) in the rotating direction of the wheel retainer (720) in order to rotate the two-way driver (710).
Abstract:
The present invention relates to a sunshade driving device having the function of returning a driving wheel, comprising: a manual driving module (40a) being operated by a ball chain or a rotating rope; a pickup member (50) for driving the rotational axis of a sunshade via the drive of the manual driving module (40a); and a wheel driving member (700) including a manual pulley (700a) having the ball chain or the rotational axis inserted therein. The drive of the manual driving module (40a) is started by the rotation of the manual pulley (700a) and is stopped by the self-load of a sunshade device if the rotation of the manual pulley (700a) stops. The wheel driving member (700) includes a bidirectional switch clutch member (710) rotating together with the manual pulley (700a) when rotating the manual pulley (700a) in one direction but rotating independently from the manual pulley (700a) when rotating autonomously in an opposite direction immediately after rotating together with the manual pulley (700a) in the one direction.

PURPOSE: An awning driving device including a returning function of a driving wheel member is provided to include a safety protecting function for children capable of a children safety accidents counteracting function and a children safety securing function which is electrically operated and to be manually and automatically used. CONSTITUTION: An awning driving device (400b) including a returning function of a driving wheel member comprises one or more pickup members (452,452') and a wheel driving member (415'). The pickup member directly drives an awning rotary shaft by a manual driving module (410). The wheel driving member comprises a manual driving wheel or a manual pulley and a two-way driving clutch. The two-way driving clutch comprises a two-way driver and a roller member. [Reference numerals] (AA) Bracket
Abstract:
The present invention is to provide an overlapped two-way clutch assembly for a rotary body driving apparatus which is safe, generates low noise, has great durability due to not using a lubricant at all, and is applicable regardless of various weights, and does not use a wrap spring. The overlapped two-way clutch assembly for a rotary body driving apparatus includes two-way driving clutch assemblies (710, 720, 730) rotatably coupled at a temporary driving member to transfer power of the driving member only in a forward direction; two-way driven clutch assemblies (740, 750, 760) transferring the power transferred from the two-way driving clutch assemblies only in the forward direction to output the power of the two-way driving clutch assemblies to the outside; and an insertion body selectively attached to or detached from the two-way driven clutch assemblies. When the power of the temporary driving member is transferred in the forward direction, the power transfer from the two-way driving clutch assemblies to the two-way driven clutch assemblies is selectively carried out. When inadvertent power is applied in the direction opposite from the forward direction, the power transfer inside the two-way driven clutch assemblies is locked in the insertion body and a brake is operated and the two-way driving clutch assemblies are in a release state.
Abstract:
The present invention relates to a driving wheel safety chain assembly of a shade driving apparatus having a spring handle for child safety in which the manufacturing cost is inexpensive and one end of a ball chain or a rotary chain having a silent operation relationship is wound or unwound. The driving wheel safety chain assembly of a shade driving apparatus having a spring handle including at least one pickup member directly driving a rotary shaft of the shade and a wheel driving member having a driving wheel includes a pulley integrally formed with the wheel driving member; a rotary chain (416a1a′) drawn to an outer portion rotating the pulley to be stretched in a predetermined length in a downward direction; a two-way driving clutch (415b) rotating the pulley together with the rotary shaft of the shade when rotating the pulley in any one direction, but rotating the pulley independent of the rotary shaft of the shade when the rotary shaft of the shade autonomously rotates in the opposite direction right after rotating together by the pulley in the one direction; and extending rotary chain spring handles (416b2) respectively coupled to both lower ends of the rotary chain.
Abstract:
The present invention provides a clutch assembly with an improved slip phenomenon which is minimized in pulling and slip, can be used as a two-way clutch or restrictively used as an one-way clutch, and is easy to manufacture. The clutch assembly includes two-way drivers (711′, 711″) having a plurality of unit movement grooves formed on the inner circumferential surface of a body; a retainer (712) on which a plurality of resilient member holders (712b) are arranged radially; and a roller member (730) inserted between the unit movement grooves of the two-way drivers (711′, 711″) and the resilient member holders (712b) of the retainer (712) to be able to rotate, wherein the unit movement groove has a small diameter part located at the center and large diameter parts located at right and left sides, and the small diameter part and the large diameter parts are connected with one another by a continuous curvature. A left roller member and a right roller member are located at right and left sides of the small diameter part of the center of the unit movement groove so as to form a pair. An interval between the left roller member and the right roller member of the unit movement groove is smaller than an interval between the left roller member of the unit movement groove and a right roller member of a neighboring unit movement groove, such that a distance where the left and right roller members (713) move relatively is reduced in comparison with a case that the left and right roller members do not form a pair.
