Description

BACKGROUND OF THE INVENTION Field of the Invention [0001] The present invention relates to an internal blind using an angle adjusting device and an angle adjusting device,

The present invention relates to an angle blind used in a window-type blind disposed inside a double window or a window top frame, and an internal blind using an angle adjusting device.

In general, blinds have been used as a means to block the sunlight or to prevent the viewer from seeing the inside from the outside, so that they can be adjusted to the surrounding environment and the indoor atmosphere.

The windows used for high-rise buildings and roads with high noise levels have installed blinds on the frames, but due to the differences in the interior space and sense of aesthetics of the blinds, the number of people who regard the blinds as interior decorations increases, Since it is difficult to install blinds, blinds that are built into windows have been developed and used according to the requirements of built-in windows with blinds attached from the beginning with blinds and windows.

However, as described above, the blinds built in the window are usually connected to a plurality of slats by a pull cord, a ladder string, etc., and the slats are adjusted by a knob connected to one side of the window to open and close the blind , Which is used to control the degree of mining. When the blinds are built in a window or are built in to tilt (relax) or pull (relax) the opening and closing lines for controlling the slats, And a device for preventing the slant from being tilted to one side has started to appear.

A registered trademark of the Korean Utility Model Registration No. 1993-3878 discloses a floor with a built-in blind. In the official gazette registration No. 20-195677, a blind device,

In this publication, there is disclosed a window provided with a fixing frame for fixing a shielding device for blocking sunlight between two-layer glass (K)

In the Publication No. 1993-0003878, the floor with the blinds,

The publication No. 20-0211757 discloses a device for adjusting the sunlight amount of a double glass (K) window and a film changer for advertisement films,

The present invention also relates to a method of manufacturing a golf club having a base on which wheels for movement are installed on respective lower rims and a base on the upper side of the base which can be raised and lowered in vertical and horizontal positions, A tilting frame provided with a plurality of conveying guides for supporting and conveying the glass, and a conveying unit having a plurality of conveying rollers rotatably provided on a lower front surface of the tilting frame and rotated in conjunction therewith.
