KR-20260063909-A - SLIT BLINDE HAVING SLIT SADJUSTMENT DEVICE

Abstract

The present invention relates to a slat blind having a lifting height adjustment device comprising a bottom bar to which a lift tape is coupled and a lifting height adjustment unit provided on the bottom bar, wherein the bottom bar includes a bar bottom cover coupled to cover the lower part and a bar center portion coupled to such that the upper part of the lifting height adjustment unit protrudes, and the bar bottom cover is provided with a gear adjustment hole that is a hole to allow rotational operation of the adjustment gear of the lifting height adjustment unit, and the lifting height adjustment unit includes an adjustment gear that fixes and winds the lift tape and an adjustment case installed so that the adjustment gear is partially exposed to allow gear adjustment. The height of each lift tape can be adjusted according to the raising and lowering of the blind slats, thereby keeping the blind slats flat.

Description

Slat blind having a slat leveling device The present invention relates to a slat blind having a bottom bar leveling device that uniformly adjusts the different heights of the bottom bar of the slat blind. Typically, blind devices installed on building windows, which are operated manually or by an automated device using a motor, control privacy protection, heating, and the amount of light by raising or lowering the blind slats or adjusting the inclination angle of the blind slats, while multiple blind slats of a certain width and length are installed at regular intervals. Generally, a slat blind comprises a blind housing, a slat lifting/tilting member provided inside the blind housing, a driving motor provided to be driven by being electrically connected to the slat lifting/tilting member, blind slats provided at equal intervals on the lower part of the blind housing, a blind bottom bar provided at the bottom of the blind slats, a lift tape connected to the blind housing side that is connected to the blind bottom bar, penetrates the blind slats, and is connected to the slat lifting/tilting member, a tilting cord that restrains the blind bottom bar and the side of the blind slats and is connected to the slat lifting/tilting member, and a control unit that controls the operation of the driving motor according to the operation of the user's control unit. However, the conventional invention had a problem in which the height of the bottom bar varied as the lifting height of multiple lift tapes varied depending on the lifting of the blind slats. In addition, there was a problem where the lift tape had to be restored by raising all the blind slats to their maximum extent to fully extend or rewind the lift tape. FIG. 1 is a drawing showing a slat blind including a slat blind having a bottom bar horizontal adjustment device showing an embodiment of the present invention. FIGS. 2 and 3 are drawings showing a slat blind having a bottom bar leveling device showing an embodiment of the present invention. FIG. 4 is a disassembled view of a slat blind having a bottom bar leveling device showing an embodiment of the present invention. FIGS. 5 and 6 are drawings showing a lifting height adjustment part of a slat blind having a bottom bar horizontal adjustment device showing an embodiment of the present invention. FIG. 7 is a drawing showing the lower bar bottom cover of a slat blind having a lower bar horizontal adjustment device, which shows an embodiment of the present invention. FIG. 8 is a cross-sectional view of FIG. 2. FIG. 9 is a drawing showing a slat blind having a bottom bar horizontal adjustment device showing an embodiment of the present invention. The following is a detailed description based on the attached drawings. The present invention enables the tilting angle to be adjusted according to the user's operation and ensures that the tilting operation is clearly performed. The terms and words used in this specification and claims should not be interpreted as being limited to their ordinary or dictionary meanings, and should be interpreted in a meaning and concept consistent with the technical spirit of the present invention, based on the principle that the inventor can appropriately define the concept of the terms to best describe his invention. Therefore, the embodiments described in this specification and the configurations illustrated in the drawings are merely the most preferred embodiments of the present invention and do not represent all of the technical ideas of the present invention; thus, it should be understood that various equivalents and modifications that can replace them may exist at the time of filing this application. That is, the present invention relates to a slat blind, A slat blind comprises a blind housing, a slat lifting/tilting member provided inside the blind housing, a driving motor provided to be driven by being electrically connected to the slat lifting/tilting member, blind slats provided at equal intervals on the lower part of the blind housing, a bottom bar (100) provided at the bottom of the blind slats, a lift tape (10) connected to the bottom bar (100) and passing through the blind slats to be connected to the blind housing side connected to the slat lifting/tilting member, a tilting cord (30) that restrains the side of the bottom bar (100) and the blind slats and is connected to the slat lifting/tilting member, and a control unit that controls the operation of the driving motor according to the operation of the user's control unit. The lower bar (100) is equipped with a lifting height adjustment unit (200) for adjusting the lifting height of the lift tape (10). The lower bar (100) includes a bar lower cover (110) coupled to cover the lower part, a bar center part (120) coupled so that the upper part of the lifting height adjustment part (200) protrudes, and a bar upper cover (130) that covers the upper part of the bar center part (120) and through which the lift tape (10) passes
