Abstract:
In a roller for movement positioned between a fixed part and a moving part so as to smoothly move the moving part on the fixed part, the roller for movement can move a moving part of heavy load and can be mounted even in the low height of mounting spaces, since the roller for movement includes a load supporting plate of flat panel shape supporting the load of the moving part, and a rolling unit of loop shape rolled on the load supporting plate to rotate with respect to the load supporting plate while the moving part moves along the fixed part, wherein the rolling unit of loop shape comprises, a plurality of rolling members, and a link unit that links the plurality of rolling members so that the plurality of rolling members are evenly distributed one another on the surface of the load supporting plate with the predetermined distances.
Abstract:
Disclosed is a coupling structure for a movable sash frame assembly in a horizontal sliding sash window system, the coupling structure including a rail guide assembly and a roller assembly respectively positioned above and below frames of a movable sash so that the movable sash can slide along top and bottom rails fixedly installed on a window frame and move together with a displacement component perpendicular to a direction of extension of the rails to be opened/ closed relative to the window frame, wherein U-shaped channel guides of a predetermined length are integrally installed above and below the frames of the movable sash, respectively, a bottom plate of the rail guide assembly connected to an opening/closing operation means and a top plate of the roller assembly connected to the opening/closing operation means are inserted into internal space of the U-shaped channel guides while being able to slide in a tilted direction, respectively, so that the frames of the movable sash and the U-shaped channel guides can have a relative movement displacement in a tilted direction with regard to the rail guide assembly and the roller assembly, respectively, and structures for fitting guide protrusions into tilted guide grooves are provided between the U-shaped channel guides and the bottom plate of the rail guide assembly and the top plate of the roller assembly, respectively, so as to guide a sliding movement displacement of the rail guide assembly and the roller assembly in the tilted direction.
Abstract:
Disclosed is a more stable and durable double coupling structure for a movable sash frame assembly in a horizontal sliding sash window system having a fixed sash adapted to remain stationary and a movable sash adapted to slide relative to the fixed sash to be opened/closed, the structure having double tilted guide grooves and double guide protrusions for connecting movable sash frames to a roller assembly and a rail guide assembly, respectively, so that, when the movable sash is opened/closed, the movable sash frames integrally compress the sealing member around the window frame in a perpendicular direction.
Abstract:
Provided are an apparatus and method for opening and closing a window by slidably moving a movable window sash or door (hereinafter collectively called a 'movable window sash') with respect to a fixed window sash or door (hereinafter collectively called a 'fixed window sash'). The apparatus is designed such that the movable window sash cannot only slide along a rail mounted within a blank frame but also be separated from a roller to move back and forth from any position on a rail toward the blank frame or the fixed window sash in a perpendicular direction with respect to a length direction of the rail, thus allowing the entire seal member interposed between either the blank frame or the fixed window sash and the movable window sash to be uniformly pressed in the perpendicular direction. Thus, excellent soundproofing, air tightness (windproofing), water tightness, insulation performance, and wind pressure resistance can be provided. Furthermore, the sliding window system has a simplified opening/closing structure and a minimum number of components, and low manufacturing cost.
Abstract:
Disclosed therein is a brush for make-up used when a user puts powder, which is base cosmetics, on her or his face, and more particularly, to a brush for make-up that a pumping means of a simple structure is embedded, thereby enabling the user to more easily apply makeup. The brush for make-up includes: a brush connection member having a brush part attached on an end thereof and a discharge hole formed on the other end thereof; a powder housing for containing powder therein and having an opening formed on an end portion; an elastic pumping tube coupled to the other end of the brush connection member and the end portion of the powder housing, for supplying the powder to the brush part by an expansion and contraction action, the elastic pumping tube having a through-hole penetratingly formed at the center thereof to define a passageway for communicating the opening and the discharge hole with each other; a guide member having a guide slot longitudinally formed on the outer periphery thereof and having a hollow space formed therein for inserting the brush connection member and the elastic pumping tube thereto, the guide member being coupled to the end portion of the powder housing; a movable member having a hollow space formed therein for inserting the guide member thereto and having a protrusion formed on the inner periphery so as to be engaged with the guide slot and move along the guide member; and a cover member coupled with the movable member.
