The present invention relates to a ball chain compound drive string and a clutch apparatus using the same. The ball chain compound drive string feels good and is exquisite like a rotation string manufactured of a cord of a textile material, and can accurately transmit power or perform a delicate relative motion without slipping like a ball chain that has a plurality of balls formed on a fine thread at a predetermined interval to function as a gear. The clutch apparatus employing the same does not slide unlike the rotation string manufactured of a cord of a textile material, and makes less gear noise unlike the ball chain. According to the present invention, in addition to the aforementioned features, there is an additional effect of easily combining various means for the safety of children with one or a part of a plurality of balls formed on a fine thread at a predetermined interval. In particular, since a delicate relative motion can be performed without slipping during the transmission of power, it is possible to apply a repeated drive type of clutch using a rotation string manufactured of a cord of a textile material which could not accurately return to the original position by a drawn length, thereby contributing greatly to the safety of children.
A sunblind driving apparatus having a function of returning a driving wheel member is disclosed. The sunblind driving apparatus includes: a manual driving module (410) operated by a ball chain or a rotation string; a rotation shaft (421) detachably connected to the manual driving module by a separate power driving means or a rotation shaft stopping means; at least one pick-up member (452, 452') for driving a sunblind rotation shaft by the rotation of the rotation shaft (421) according to driving of the manual driving module (410) or directly driving the sunblind rotation shaft by the manual driving module (410); and a wheel driving member (415') having a manual pulley (415a) or a manual driving wheel (412b) in which the ball chain or the rotation string is inserted. The wheel driving member (415') includes a bi-directional clutch (415b), which rotates together when the manual driving wheel (412b) or the manual pulley (415a) is rotated in one direction, and rotates independently of the manual driving wheel (412b) or the manual pulley (415a) when the bi-directional clutch (415b) rotates by itself in the opposite direction instantly after rotating together with the manual driving wheel (412b) or the manual pulley (415a) in the one direction.
A device for controlling the gap between slats of the present invention comprises: a driving gear (94i) inserted into a spline of a rotating shaft for gap control in a linearly movable manner and provided at a gap control housing (97c); at least one driven gear (94j) engaged with the driving gear (94i), provided at the gap control housing (97c) together with the driving gear (94i), and rotatably provided at a guide hole (P'); a nut (92g) corresponding one-to-one to any one of the driven gears (94j), and non-rotatably provided at the guide hole (P') formed adjacent to the gap control housing (97c) in which the driven gears (94j) are provided; and a bolt/screw (92f) fixed to any one of the driven gears (94j), first passing through the nut (92g), and slidably inserted into the guide hole (P') of the adjacent gap control housing (97c) for accommodation. The device for controlling the gap between slats can freely control gaps between slats.
The present invention relates to a 2-axis tracking apparatus, and to a 2-axis tracking apparatus for a sunshade apparatus having a plurality of frame slats (S2) and one or more mini slats (S1) fitted to the respective frame slats (S2) to be rotatable, wherein the 2-axis tracking apparatus comprises: mini slat angle adjusting means for adjusting the angles of the mini slats (S1); frame slat angle adjusting means for adjusting the angles of the frame slats (S2); first power transmission means for transmitting power to the mini slat angle adjusting means; and second power transmission means for transmitting power to the frame slat angle adjusting means. The first power transmission means and the second power transmission means act on the respective mini slat angle adjusting means and the frame slat angle adjusting means independently of each other without a mutual interference. The rotating directions of the frame slats (S2) and the rotating directions of the mini slats (S1) fitted to the frame slats (S2) intersect with each other. The 2-axis tracking apparatus of the present invention may precisely track both of a solar azimuth angle and a solar altitude angle while performing a unique sunshade or lightening function of a sunshade apparatus. The 2-axis tracking apparatus of the present invention may be installed anywhere, maximizes solar energy use efficiency, has a simple structure to allow for ease of installation, is not bulky which enables installation of the apparatus in an indoor area, and may be manufactured in an inexpensive manner.

BLIND HAVING A FLOW CHANNEL, AND FLOW CHANNEL SLAT
According to the present invention, a blind having a flow channel (hereinafter referred to as a "flow channel blind") comprises: a blind slat (hereinafter referred to as a "flow channel slat") in which a flow channel for flowing material is formed in at least a portion of the interior thereof; angle adjustment means for adjusting the angle of the flow channel slat; and at least one connecting pipe for flowing material, connected between the flow channel slats so as to form a flow channel therebetween. The flow channel slats are interconnected so as to form multiple stages through the connecting pipe for flowing material in order to form a flow channel, such that the flowing material introduced into the flow channel slats flows along the flow channel. Using the thus-configured flow channel blind, flowing material, such as air, in the flow channel can be heated by solar energy and supplied as high-temperature air. The flow channel blind of the present invention can be applied to conventional garbage disposals to reduce power consumption and achieve economical advantages. In addition, the flow channel blind of the present invention can be valuably used in a variety of fields such as a photovoltaic module cooling system or the like.
