Description

Horizontal Window Blind

The present invention relates to a horizontal window blind that is attached to the inner wall of an indoor window to block outside sunlight from shining into the interior, and more specifically, to a horizontal window blind that does not use a cord-winding method for adjusting the height of a curtain that controls the area of sunlight blocked, thereby preventing the cord from becoming tangled, and can ventilate the upper air of the interior by gathering the curtain downward.

Window blinds are made up of multiple individual shading panels or curtains attached to the inner wall of an indoor window to block sunlight or protect personal privacy.

Window blinds using sunshades are divided into horizontal and vertical types. In horizontal window blinds, a means of adjusting the position of the sunshade is generally adopted, in which a string is connected to the sunshade and a roller is configured on the upper side to which the string is wrapped, and the string is wrapped around the roller.

This configuration can cause inconvenience in use due to tangling as the string is wound or unwound around the roller, and as a prior art having this problem, Korean Patent No. 10-157252, “Blind device with easy horizontal adjustment,” is disclosed.

In the technology, the spool unit is described as having an outer surface for winding or unwinding a cord thread connected to the lower part of the shading unit, and being operated to rotate to raise or lower the shading unit by the cord thread. However, this structure has a structural problem in that the cord thread (line) may become tangled as it is wound or unwound on the spool unit (roller).

As an example of another prior art, Korean Patent No. 10-210927, “Dual Semi-Automatic Blind,” is disclosed.

The technology comprises an upper adjustment line wound around an upper adjustment member drum and an end of which is fixed to the upper frame of the blind screen, and a lower adjustment line wound around the lower adjustment member drum and an end of which is fixed to the lower frame of the blind screen.

This structure also has a structural problem in that the upper and lower control lines (lines) can become tangled as they are wound or unwound around the upper and lower control member drums (rollers).

Hereinafter, the configuration of the present invention and the resulting operation and effects will be described in detail with reference to the attached drawings.

The advantages and features of the present invention, and the methods for achieving them, will become clearer with reference to the embodiments described in detail below together with the accompanying drawings. However, the present invention is not limited to the embodiments disclosed below, but can be implemented in various different forms. The present embodiments are provided only to ensure that the disclosure of the present invention is complete and to fully inform those skilled in the art of the scope of the invention, and the present invention is defined only by the scope of the claims. In addition, like reference numerals refer to like elements throughout the specification.

The present invention relates to a horizontal window blind having a structure that can prevent malfunction due to tangled strings used to adjust the position of a window blind by being attached to the inner wall of an indoor window to control the amount of sunlight entering, and is configured to include a cover (10), a fixing member (20), a first moving member (30), and a shading film (40), as shown in FIGS. 1a to 1e.

The cover (10) is a square frame attached to the inner wall of a window and has a cross-section in the shape of the letter 'ㄷ'. In addition, a square plate-shaped fixing member (20) is provided on the front and back of the inside of the left and right sides of the cover (10).

The first transfer member (30) is configured to include a slide member (31) configured on both sides so that both sides are in close contact with the fixed member (20) and can be adjusted in height and position, as shown in FIGS. 1b to 1d, and a body (32) configured between the slide members (31) on both sides.

The upper part of the shade film (40) is attached to the lower part of the body (32) and is pulled by the up-and-down movement of the first transfer member (30). The material of the shade film (40) can be made of cloth or paper, and has a shape that can be folded in a zigzag pattern.

The above fixed member (20) is made of a steel plate, and a magnet (31a) is provided on the contact surface of the slide part (31) that comes into contact with the fixed member (20), so that the magnet (31a) sticks to the fixed member (20) by magnetic force, thereby preventing the slide part (31) from slipping off the fixed member (20).

In order to adjust the height at which the sunshade (40) covers the window, the user must adjust the height of the first transfer member (30), and a handle (32a) may be formed on one side of the body (32) so that the user can hold it with his/her hand when adjusting the height of the first transfer member (30).

With the above configuration, when the user raises the height of the first transport section (30), the barrier (40) is pulled upward and unfolds by its own weight, and when the height of the first transport section (30) is lowered, the lower side of the barrier (40) is supported by the cover (10), so that it folds.

The hot air inside the room is directed upwards, and by folding the curtain (40) downward as shown in Fig. 1e to ventilate the indoor air, the heat and dust in the upper part of the room can be discharged to the outside.

In addition, by using magnets to adjust and fix the upper and lower positions of the barrier, the problem of string tangling does not occur, and the configuration is simplified, which is advantageous in reducing manufacturing costs.

Example 2 is identical to the configuration of Example 1, except that a second transfer member (30') is configured at the bottom of the barrier in the configuration of Example 1, as shown in FIGS. 2a to 2e.

The second transfer member (30') is configured to include a slide member (31') that is configured on both sides so that both sides are in close contact with the fixed member (20) and that can be adjusted in height and position, and a body (32') configured between the slide members (31') on both sides.

The lower end of the shade film (40) is attached to the upper end of the body (32') and the lower end of the shade film (40) is pulled by the up-and-down movement of the second transfer member (30).

A magnet (31a') is provided on the contact surface of the slide portion (31') that comes into contact with the fixed member (20), so that the magnet (31a') adheres to the fixed member (20) by magnetic force, thereby preventing the slide portion (31') from slipping off the fixed member (20).

Additionally, a handle (32a') may be formed on one side of the body (32') so that the user can grip it with his/her hand when adjusting the height of the second transport section (30').

By adjusting the first transfer unit (30) and the second transfer unit (30') with the above configuration, the barrier (40) can be folded and gathered on the upper side of the inside of the cover (10) as in Fig. 2d, and can also be folded and gathered on the center of the inside of the cover (10) as in Fig. 2e, so that the position of the barrier (40) can be freely adjusted.

Example 3 is the same as the configuration of Example 1 or Example 2, except that the slide part (31, 31') is not provided with a magnet (31a) in the configuration of Example 1 or Example 2, and is fixed to the fixing member (20) using a spring (S) and a pusher (P), as shown in FIG. 3.

A plurality of pushers (P) are provided on both sides where the slide part (31, 31') and the fixed member (20) come into contact, and a spring (S) is provided in the space between the pushers (P) to push the pushers (P), thereby pressurizing the pushers (P) against the fixed member (20), thereby preventing the slide part (31, 31') from slipping off the fixed member (20).

In Example 3, the material of the fixed member (20) is not a steel plate, and hard polyurethane can be used to prevent the pusher (P) from slipping on the fixed member (20).

Additionally, the pusher (P) can be configured to directly contact the inner surface of the cover (10) without forming a fixed member (20).

Example 4 is identical to the configuration of Examples 1 to 3, except that a hook (11), a hinge (33), and a control rod (50) are further configured in the configuration of Examples 1 to 3, as shown in FIGS. 4a to 4d.

The first and second transport members (30, 30') can be configured to rise to a height that is difficult for a user's hand to reach, and in Example 4, a catch (33) is configured on one surface of the first and second transport members (30, 30').

A circular shaft (33a) is formed in the hook (33), and a control rod (50) is provided with a gripping portion (51) that can be pushed up or pulled down by hooking to the shaft (33a).

The grip section (51) is opened at one end so that it can be inserted into or removed from the shaft (33a), and is formed with a structure that surrounds the upper and lower surfaces of the shaft (33a) so that force is transmitted to the shaft (33a) when the user pushes the rod up or pulls it down.

When the control rod (50) is not in use, a hook (11) may be provided on the left and right outer sides of the cover (10) so that it can be stored. The hook (11) is formed in a circular pin shape so that the grip part (51) can be hung on the hook (11) to store the control rod (50).

The present invention described above has been described with reference to one embodiment illustrated in the drawings, but this is merely exemplary, and it should be made clear that various modifications and equivalent other embodiments are possible for those skilled in the art. Therefore, the true technical protection scope of the present invention should be interpreted by the appended claims, and all technical ideas within a scope equivalent thereto should be construed as being included within the scope of the present invention.
