Abstract

The present invention relates to a blind and, particularly, to a liftable blind of which a shielding unit for covering light and the lower side of a window is moved from the upper end of the window so as to adjust lighting at the upper side of the window, and thus the convenience of use of a consumer can be maximized.

Description

Lifting movable blinds

The present invention relates to a blind, and more specifically, to move the shield covering the light as well as the lower side of the window from the top of the window, it is also possible to adjust the light on the upper side of the window to the movable movable blind that can maximize the convenience of the consumer will be.

Generally, blinds are installed on windows of buildings, such as houses or offices, for the purpose of light control and privacy protection. These blinds are divided into vertical and horizontal opening and closing types depending on the opening and closing method, but only the opening and closing directions are different. Do.

These vertically-openable and horizontally-openable blinds are divided into manual and electric, depending on the operation method. The manual blind can be opened and closed by a user's desired length by pulling a string, and the electric blind is equipped with a motor and a power transmission device inside the rail of the blind to automatically open and close the shield.

However, in the case of an existing blind, for example, a vertically open-closed blind, the lower light of the window can be adjusted by adjusting the length of the lower part of the shield member while the top of the blind is fixed to the upper end of the window frame. , Since the upper end of the shielding member is always fixed on the upper side of the window frame, it is virtually impossible to adjust the upper side of the window.

In order to solve this problem, in Korean Registered Utility Model No. 20-0339981 (Registration date: 2004.01.15.), the upper support is separated from the frame on the upper part of the light-shielding device, and the upper support is moved up and down by the tow line. There has been proposed a'shielding device operating in both directions, up and down,' which can open and close the upper side as well as the lower side.

However, in the shading device proposed in Republic of Korea Utility Model No. 20-0339981, each failure fitted to the roller shaft alternately rotates according to the frictional force with the roller shaft, or even when the roller shaft is rotating, it is stopped by the force that overcomes the frictional force. Repeating or operating the shading device. That is, when turning the roller shaft, almost one of the failures is in a stopped state. Therefore, there is a fear of noise generation every time the product is operated, and it is inevitable to avoid energy loss due to an increase in driving force and in particular, a significant decrease in durability due to abrasion.

In addition, in the shading device proposed in Korean Registered Utility Model No. 20-0339981, the shading is adjusted by moving the wing of the blind while the upper support towing failure turns to control the shading of the horizontal blind. Therefore, from the point where the upper support towing failure fails, that is, from the point where the roll rotates forward and the blinds from the lower side block the entire window, the blinds that continue to rotate forward and fold from the lower side are all folded to the upper housing side to open the entire window. It is unique to the design because the blinds that were folded on the upper housing side by rotating the section and the roll that can no longer be rotated all the way to the lower side are unable to adjust the shading in almost all sections until the point of blocking the entire window. You can't expect one purpose at all.

Meanwhile, in the Republic of Korea Registered Utility Model No. 20-0477536 (registration date: 2015.06.16.), the shading screen is provided through the first and second shafts, and the first and second winding rollers coupled to the first and second shafts. Reliability of product operation was improved by suggesting a blind that can be opened and closed vertically to selectively open and close either one of the upper and lower sides of the window by lifting up and down.

However, the Republic of Korea Registered Utility Model No. 20-0477536 requires two shafts arranged side by side and wound with the first and second towing lines to elevate the light-shielding screen up and down, and also to independently drive them. As the first and second drive chains are required, the structure is not only complicated, but also inconvenient for the user to operate.

Therefore, the present invention has been proposed to solve the problems of the prior art, and it is possible to maximize the user's convenience by moving the shield covering the light as well as the lower side of the window from the top of the window so that the light on the upper side of the window is also adjustable. Its purpose is to provide a movable movable blind that is simple to install and easy to operate.

Referring to FIG. 1, the elevating movable blind 10 according to an embodiment of the present invention is, for example, a vertically open and closed blind, and may be implemented manually or electrically depending on a driving source.

The lifting movable blind 10 includes a shaft 11 having a substantially rod shape.

When the lifting movable blind 10 is manually implemented, the shaft 11 is provided with a drive gear (not shown) at one end and a housing (or cover) at which the shaft 11 is inserted and coupled inside. (Not shown) is rotatably coupled through an end bracket. At this time, a drive chain (or code) for rotating the shaft 11 is connected to the drive gear.

On the other hand, when the lifting movable blind 10 is implemented electrically, the shaft 11 is coupled to a drive motor (not shown) at one end, and the housing 11 is coupled to the other end of the shaft 11 (or). Cover) to the end bracket. Accordingly, the shaft 11 is rotated automatically by receiving the rotational force according to the driving of the drive motor coupled to one end.

As shown in FIG. 1, the lifting movable blind 10 according to the embodiment of the present invention includes a connecting line 12 and a shield 14 connected to the shaft 11 by the lifting line 13.

The connection line 12 determines the height of the lower side of the shield 14 when the shield 14 is deployed to the lower side of the window relative to the shaft 11. At this time, the unfolding of the shield 14 refers to a state in which the shield 14 is folded in a wound state by being rolled up on the shaft 11, and the deployment of the shield 14 is a shield. After the 14 is released from the shaft 11, the lower support member 142 is lowered to the maximum value defined by the connection line 12, which means that the shielding member 143 is fully unfolded.

One end of this connection line 12 is coupled to the shaft 11 in a circular ring structure, and the other side is connected to the lower support member 142 via the shield member 143.

Accordingly, the connecting line 12 is basically wound on the outer circumferential surface of the shaft 11 together with the shielding member 143 when the shaft 11 rotates in one direction, and when the shaft 11 rotates in the opposite direction, the shaft 11 ) From the shielding member 143.

On the other hand, the connecting line 12 according to the present invention is idle without being wound on the outer circumferential surface of the shaft 11 according to the rotation of the shaft 11.

To this end, the connection line 12 may be coupled to the outer circumferential surface of the shaft 11 in a state in which one end coupled to the shaft 11 is knotted in a circular ring structure. At this time, one end of the connecting line 12 made of a circular ring structure may be made of the same material as the other parts, or may be made of a circular ring made of another material, for example, a metal material or a synthetic resin material.

In this way, the connection line 12 according to the present invention, even if the shaft 11 rotates as one end is coupled to the shaft 11 in a state made of a circular ring structure, the connection line 12 is idle on the outer circumferential surface of the shaft 11 By the connection line 12, it does not wind on the outer circumferential surface of the shaft 11, but is idle.

On the other hand, in the present invention, an idle member (not shown) may be additionally installed so that the connecting line 12 idles on the outer circumferential surface of the shaft 11.

The lifting line 13 is for opening and closing the upper side of the window by elevating the shield 14, one end is wound on the shaft 11, the other end is fixed to the upper bar 141 of the shield 14 .
