Description

INTEGRATED BLIND}

The present invention relates to a blind installed on a window to block or control light.

Blinds are devices installed to block sunlight or prevent viewing of the inside of a building, and are similar to curtains in that they cover windows. Curtains covered with fabric on the entire window or wall control the light coming from outside and provide excellent interior design, but they have the disadvantage of being difficult to wash frequently and collecting dust. In comparison, blinds are preferred because they are easy to remove dust and have the advantage of being able to precisely control the amount of light. Blinds are generally in the form of sliding down from the top, and blinds that are moved to the side to cover them are also called vertical.

A roll-up blind is a blind made of rolled blind fabric that can be pulled up or down by pulling a string. Roll blinds are commonly made of fabric or sheets, and recently, a type (combi blind) has been created that alternates between see-through mesh sections and non-see-through fabric sections, allowing the height of the blind to be raised and the amount of sunlight to be blocked all at once. was developed.

Films attached to windows as a means of blocking heat or ultraviolet rays during seasons or times of strong sunlight improve thermal efficiency by blocking heat while still transmitting light.

On the other hand, solar radiation varies greatly depending on the season or day, and films are used differently depending on their function. In the case of attaching the film directly to the window glass, attaching and detaching the film is difficult and cumbersome.

Hereinafter, the present invention and blind will be described in detail with reference to the attached drawings.

According to Figure 1, the integrated blind 100 related to the present invention is provided with two types of blocking films. These blocking films include a first roll 110 that has a heat insulating and blocking function against sunlight and a second roll 120 that has light blocking properties. The first roll 110 and the second roll 120 are rolled up by respective winding shafts installed at the top, and are configured to be raised and lowered by a winding rope 140 provided on one side. The winding axes of the first roll 110 and the second roll 120 are vertically parallel, and the elevation surfaces of the first roll 110 and the elevation surfaces of the second roll 120 are spaced apart in parallel front and rear. To increase the effectiveness of blocking heat and ultraviolet rays caused by sunlight, the elevation surface of the first roll 110 may be placed toward the window, and the elevation surface of the second roll 120 may be disposed toward the interior.

The first roll 110 may be in the form of a film capable of insulating and blocking sunlight or ultraviolet rays. The film constituting the first roll 110 may be selected based on the heat transmittance, shielding coefficient, solar radiation gain coefficient, visible light transmittance, and ratio of solar heat gain coefficient to visible light transmittance, etc., which are the amount of heat passed in a certain time. The first roll 110 may be configured to be interchangeable in terms of these items. The lower end of the first roll 110 may include a weight bar to maintain the lifting surface in a taut state.

The second roll 120 may be in the form of a light-blocking fabric or sheet that blocks light and does not shine through. The second roll 120 may also be formed to be replaceable to change material or function, and may be provided with a weight bar to maintain the lifting surface in a taut state.

Figure 2 shows a manipulation assembly 130 according to an example related to the present invention. An operation assembly 130 is installed on one side of the blind 100 to select or lift the first roll 110 and the second roll 120. The winding line 140 is an element that forms the manipulation assembly 130, and in this example, the first roll 110 and the second roll 120 can be operated at the same time by one winding line 140. . In addition, it is also possible to configure the first roll 110 and the second roll 120 to be raised and lowered independently. In this case, means for elevating the first roll 110 and means for elevating the second roll 120 may be separately provided, and a conventional device may be used as the elevating means.

The manipulation assembly 130 includes a winding line 140, and when the first line 141 constituting the winding line 140 is pulled, the first roll 110 is released and lowered, and the second roll 120 is wound. It is raised, and when the second line 142 constituting the winding line 140 is pulled, the first roll 110 is wound up and the second roll 120 is unwound and lowered. The winding rope 140 may be of a conventional form with beads attached to the string in order to rotate the gear units described later.

The manipulation assembly 130 may include a first gear unit 150, a second gear unit 160, and a bracket 170 in addition to the winding line 140.

The first gear unit 150 rotatably supports the first roll 110 and is formed to be rotated by being caught by the winding line 140. The second gear unit 160 also rotatably supports the second roll 120 and is formed to be rotated by being caught by the winding line 140. The bracket 170 is formed to enable installation of the first gear unit 150 and the second gear unit 160. The second gear unit 160 is disposed vertically below the first gear unit 150, and accordingly, the first roll 110 and the second roll 120 are in a vertical relationship. The winding line 140 is wound around the first gear unit 150 and the second gear unit 160 so that the first gear unit 150 and the second gear unit 160 rotate in the same direction.

The winding line 140 is installed to wind around the first gear unit 150 at the top, and the first line 141 and the second line 142 are connected to the second gear section 160 at the bottom. It is partially hung on both sides of the gear unit 160, allowing the second gear unit 160 to rotate. The second gear unit 160 has an open shape that allows the first and second rows 141 and 142 to pass up and down.

A guide unit 180 is installed on the upper or lower part of the second gear unit 160 to increase the amount of winding of the rope 140 around the second gear unit 160. This guide portion 180 may be formed in the form of a pair of shafts arranged in parallel to reduce the width between the first and second lines 141 and 142 by pushing the winding line 140. To reduce friction against the guide part 180 of the coiled line 140 and enable smooth operation, the guide part 180 may be formed in the form of a roller.

Brackets 170 are disposed at both ends of the integrated blind 100, and both brackets 170 are fixed to a rail 101 installed on the ceiling, etc.

The bracket 170 includes a horizontal extension part 171 and a vertical extension part 172, and the vertical extension part 172 is formed by being bent at 90 degrees with respect to the horizontal extension part 171. The first gear unit 150 and the second gear unit 160 are installed in the vertical extension part 172.

The vertical extension part 172 includes a first bent support part 175 that is bent to be inserted into the first gear part 150, and a first bent support part 175 to be inserted into the second gear part 160 at the lower part of the first bent support part 175. A second bending support portion 176 is provided that can be bent. The bracket 170 may be formed of metal or engineering plastic to ensure necessary rigidity. Since the bottom of the bracket 170 at both ends of the integrated blind 100 is open, both brackets ( A support member 190 may be provided to connect the lower end of 170 to maintain the distance.

Figures 3 and 4 are cross-sectional views showing the operating state of the integrated blind 100 related to the present invention. As shown in these drawings, the first roll 110 is disposed on the window W side and pulls down the first line 141 of the winding line 140 during seasons or daily hours when sunlight is strong. At the same time, the second roll 120 is wound up in the opposite direction. In order to completely block sunlight or darken the room, if the second rope 142 of the winding rope 140 is pulled in the opposite direction, the first roll 110 is wound up and the first roll 110 is unwound, as shown in FIG. 4. It comes down.

In this way, the blocking effect can be easily obtained by lowering the first roll 110 or the second roll 120 according to time or selection using a single winding line 140. In general, when it is necessary to block heat from sunlight and when it is necessary to block the interior, it is the opposite case, but it is cumbersome and economically disadvantageous to use a means or operation for heat blocking and a separate means or operation to block the interior. The integrated blind 100 of the first roll 110 and the second roll 120 related to the invention can effectively overcome this problem.

The integrated blind described above is not limited to the configuration and method of the described embodiments. The above embodiments may be configured by selectively combining all or part of each embodiment so that various modifications can be made.
