Technology Field

[0001] The present invention relates to a light-blocking motorized screen, and more specifically, to a light-blocking motorized screen that can always keep a screen taut by reciprocating in a horizontal direction or a direction close to horizontal, rather than in the direction of gravity, through a configuration added to a screen installed for the purpose of blocking light in a high place such as a ceiling, and can control light blocking by adjusting the degree of opening and closing of the screen. Background Technology

[0003] Generally, there are curtains or blinds installed near windows that are intended to block light coming from the outside, but there are structural limitations to installing them for blocking light in high places such as ceilings, and even if they are installed, there are problems such as difficulty in manually opening or closing them to block or release light, or requiring effort to operate them.

[0004] To address this, inventions that solve the problem of ceiling shading using electric power have been proposed. For example, Korean Registered Patent No. 10-2167751 (October 20, 2020), 'Shade Screen Opening and Closing Device,' is an invention that enables the opening and closing of a shade screen installed on a ceiling without using human labor by connecting the shade screen to a shade screen fixing means and a shade screen winding roll so that it can move in the longitudinal direction through a guide means, and by using a method of transmitting power via a chain using two mutually reverse-operating reduction motors.

[0005] However, the above technology has disadvantages such as requiring a wide installation space in both the vertical and horizontal directions due to the exposure of drive parts like chains, damaging the aesthetics when applied to indoor spaces, and causing inconvenience and damaging the aesthetics because there are many components exposed to the outside that must be used separately to prevent the shading screen from flapping. The problem to be solved

[0007] The present invention is intended to solve the problems of the aforementioned prior art. The light-blocking motorized screen of the present invention can always keep the screen taut by reciprocating in a horizontal direction or a direction close to horizontal, rather than in the direction of gravity, through a configuration added to a screen installed for the purpose of blocking light in a high place such as a ceiling, and can control the blocking of light by adjusting the degree of opening and closing of the screen. means of solving the problem

[0009] The light-blocking electric screen of the present invention may include two side rail frames installed on a ceiling or an installation frame; a rolling drive unit installed at one end of the side rail frames; a screen unit capable of moving along the side rail frames; and a tension maintaining unit for returning the screen unit.

[0010] And the above side rail frame may include a rail hole into which the screen part can be inserted and moved; an insertion hole in which the tension maintaining part is installed; and a partition separating the rail hole and the insertion hole.

[0011] In addition, the rolling drive unit may include a pull-out bracket installed on the side rail frame; a vertical bracket installed on the pull-out bracket; a rolling motor installed on the vertical bracket; and a rolling frame installed on the outer surface of the rolling motor.

[0012] And the screen section may include a light-blocking screen that is wound with one end installed in the rolling drive section and a guiding bar installed at the other end of the light-blocking screen.

[0013] Additionally, the tension maintaining member may include a pressure cylinder having one end formed by a piston and the other end formed by a cylinder; a first pulley section installed at the end of the piston; a second pulley section installed at the end of the cylinder; a wire wound around the first pulley section and the second pulley section; and a connector installed at the end of the wire and coupled to a screen section.

[0014] And the above rolling drive unit further includes a rolling frame insertion groove formed in the rolling frame to allow the screen unit to be inserted and coupled, and the screen unit may further include a guiding bar insertion groove formed in the guiding bar to allow the light-blocking screen to be inserted and coupled.

[0015] Finally, the screen portion may further include one or more anti-sagging devices installed on the shading screen. Effects of the invention

[0017] The light-blocking electric screen according to an embodiment of the present invention can always keep the screen part, which reciprocates in a horizontal direction or a direction close to horizontal rather than the direction of gravity, taut through a rolling drive unit and a tension maintaining unit.

[0018] In addition, since the above components are installed inside and between the frames without being exposed to the outside, there is no external exposure of complex components such as rotary motors, cylinders, and wires, which has the advantage of not detracting from the interior landscape.

[0019] In addition, through the anti-sagging device, when the shading screen is wound and unwound according to the rotation of the rolling frame, it is positioned at regular intervals on the shading screen to prevent sagging of the shading screen, which is prone to folding or creasing.

[0026] Hereinafter, a light-blocking electric screen according to an embodiment of the present invention will be described in detail with reference to FIGS. 1 to 15.

[0028] Referring to FIG. 1, the light-blocking electric screen (1) of the present invention can be installed on a ceiling or an installation frame (F), and FIG. 1 shows the light-blocking electric screen (1) installed on the installation frame (F).

[0029] This installation frame (F) is used in cases where it is difficult to install the light-blocking motorized screen (1) directly on the ceiling surface or where it must be installed outdoors where there is no ceiling, and can serve as an auxiliary means to easily install the light-blocking motorized screen (1).

[0030] Referring to FIG. 2, the light-blocking motorized screen (1) installed on the ceiling or installation frame (F) can block external light rays coming from above by opening and closing the screen part (30).

[0031] Referring to FIG. 3, the light-blocking electric screen (1) may be configured to include two side rail frames (10), a rolling drive unit (20) installed at one end of the side rail frames (10), a screen unit (30) that moves along the side rail frames (10), and a tension maintaining unit (40) that pulls the screen unit (30) back.

[0032] The side rail frame (10) may be configured to include a rail hole (11) into which a screen part (30) can be inserted and moved, an insertion hole (12) into which a tension maintaining part (40) is installed, and a partition wall (13) that divides the rail hole (11) and the insertion hole (12).

[0033] Additionally, the side rail frame (10) may be formed in the shape of a straight bar with a square cross section and may be configured to include one or more ceiling brackets (14) so ​​as to be installed on a ceiling or an installation frame (F).

[0034] The rolling drive unit (20) may be configured to include a pull-out bracket (21) installed at one end of the side rail frame (10), a vertical bracket (22) installed on the pull-out bracket (21), a rolling motor (23) installed on the vertical bracket (22), and a rolling frame (24) installed on the outer surface of the rolling motor (23).

[0035] The screen section (30) may be configured to include a light-blocking screen (31) that is wound with one end installed on the rolling drive section (20) and a guiding bar (32) installed on the other end of the light-blocking screen (31). FIG. 3 shows the state in which the light-blocking screen (31) of the screen section (30) is wound on the rolling drive section (20), and accordingly, the top is open so that the light-blocking electric screen (1) does not block light.

[0036] Referring to FIG. 4, the light-blocking electric screen (1) of FIG. 4 shows the state in which the light-blocking electric screen (1) is blocking light, with the screen part (30) that was wound on the rolling drive part (20) moving along the rail hole (11) formed in the side rail frame (10) and the light-blocking screen (31) unfolded.

[0037] Referring to FIG. 5, the internal structure of the side rail frame (10) can be examined in detail. First, the rail hole (11) formed in the side rail frame (10) is a hole that is cut along the length of the side rail frame (10) as shown in the drawing, and is separated from the insertion hole (12) by a partition wall (13) that vertically divides the interior of the side rail frame (10). The size of the hole can be formed to correspond to the size of the screen part (30) so that the screen part (30) can move.

[0038] The side rail frame (10) serves as a guide for opening and closing the screen portion (30) of the light-blocking electric screen (1) installed on the ceiling, etc. through the rail hole (11), and performs the function of supporting it so that it does not sag in the direction of gravity. The insertion hole (12) formed between the rail hole (11) and the partition wall (13) is a space where the tension maintaining part (40), which will be described later, is installed, and can be formed to fit the size so that the tension maintaining part (40) can be installed inside.

[0039] Referring to FIG. 6, the combined structure of the components forming the rolling drive unit (20) is illustrated, and two pull-out brackets (21) that can be combined with each side rail frame (10), a vertical bracket (22) that is combined with each pull-out bracket (21), and a rolling frame (24) between the two vertical brackets (22) are illustrated.

[0040] Referring to FIGS. 7 and 8, a more detailed structure can be examined through an exploded view showing the components forming the rolling drive unit (20), and a rolling motor (23) that was not shown but is fitted inside the rolling frame (24) is shown.

[0041] The rolling motor (23) is connected at both ends to the vertical bracket (22), specifically through the circular connecting member (221) and the rod connecting member (222) included in the vertical bracket (22), and the rolling frame (24) installed on the outer surface of the rolling motor (23) can be connected so that it can rotate in both directions. Although not shown, a wire is formed at one end to supply power, and the rolling frame (24) installed on the outer surface of the rolling motor (23) can be rotated in both directions through a wired / wireless controller that controls the rolling motor (23).

[0042] However, in supplying power to the rolling motor (23), external power may be applied, but the rolling motor (23) may also include a built-in battery, so it is not limited to this.

[0043] Referring to FIG. 9, the combined structure of the components forming the screen section (30) can be seen, and a light-blocking screen (31) with one end wound on a rolling frame (24) and a guiding bar (32) installed on the other end of the light-blocking screen (31) are shown.

[0044] The other end of the shading screen (31) is inserted into one side of the guiding bar (32), and the guiding bar (32) can be opened and closed as it moves along the holes formed in the rail holes (11) of the two side rail frames (10) with parts of the left and right ends inserted into them.

[0045] As the material forming the light-blocking screen (31), a polyester synthetic resin that is thin, light, has high light-blocking power, is flame-retardant, and has little wrinkles can be used, but any material suitable for the above conditions can be used, so it is not limited to this.

[0046] Although not shown, the surface of the light-blocking screen (31) can be formed with various embossing patterns to prevent wrinkles, and glass powder can be coated to increase reflectivity and enhance light-blocking power.

[0047] Referring to FIG. 10, a tension maintaining part (40) is shown in which an insertion hole (12) formed in the side rail frame (10) is installed.

[0048] The tension maintaining part (40) may be formed by including a pressure cylinder (41) having one end formed by a piston (411) and the other end formed by a cylinder (412), a first pulley part (42) installed at the end of the piston (411), a second pulley part (43) installed at the end of the cylinder (412), a wire (44) wound around a plurality of pulleys formed inside the first pulley part (42) and the second pulley part (43), and a connector (45) installed at the end of the wire (44) and coupled with a screen part (30).

[0049] The pressure cylinder (41) can generate a restoring force that pushes the piston (411) back out through the fluid that is compressed when the piston (411) is encroached upon the inside of the sealed cylinder (412).

[0050] The first pulley section (42) and the second pulley section (43) have multiple pulleys formed therein that rotate axially, allowing the wire (44) to be wound sequentially, and the second pulley section (43) has a rotatable wire wheel (431) formed on one side so that the wire (44) can be hung thereon.

[0051] The wire wheel (431) can perform the function of allowing the wire (44) to move smoothly without friction with the bulkhead (13) when it is connected from the second pulley part (43) located in the insertion hole (12) formed in the side rail frame (10) to the rail hole (11) formed in the side rail frame (10).

[0052] Referring to FIG. 11, a plurality of holes through which a wire (44) can pass are formed on one side of the first pulley section (42) and the second pulley section (43), so that the movement of the wire (44) wound on the pulley can be made smooth.

[0053] The wire (44) is formed in the form of a single long string formed by twisting several small strands together. It can be made of a durable material that is flexible but does not stretch and does not break easily, but is not limited thereto.

[0054] Referring to FIG. 12, one end of the wire (44) is fixed to one side of the second pulley section (43) and passes through the second pulley section (43), primarily coming into contact with the pulley inside the second pulley section (43) and passing through the second pulley section (43).

[0055] And the wire (44) passes through the first pulley section (42) and is wound around the pulley inside the first pulley section (42), and then passes through the first pulley section (42) and the second pulley section (43) and is wound around the pulley inside the second pulley section (43).

[0056] In this way, the ratio of the length of the piston (411) that is encroached upon by the cylinder (412) and the length of the wire (44) wound around the first pulley section (42) and the second pulley section (43) that finally extends from the second pulley section (43) can be adjusted according to the number of times the wire (44) is wound around the first pulley section (42) and the second pulley section (43), and thereby the length of the side rail frame (10) of the light-blocking electric screen (1) to be installed on the ceiling, etc. can be adjusted and formed.

[0057] The connector (45) is installed at the end of the wire (44) that comes out through the second pulley section (43) and the wire wheel (431) formed in the second pulley section (43), and moves along the inside of the rail hole (11) of the side rail frame (10) and combines with the screen section (30) to perform the function of transmitting the tension of the wire (44) by the restoring force of the piston (411) to the screen section (30).

[0058] Looking at the operation of the tension maintaining part (40), in FIG. 10, before the piston (411) of the pressure cylinder (41) is encroached upon the inside of the cylinder (412), the connecting body (45) connected to the wire (44) is positioned close to the second pulley part (43) through the partition wall (13).

[0059] And in FIG. 12, as the screen part (30) is wound according to the rotation of the rolling drive part (20), the connector (45) combined with the screen part (30) moves along the rail hole (11) so that the piston (411) of the pressure cylinder (41) is encroached upon inside the cylinder (412).

[0060] In this process, a restoring force is formed, which is a force that returns the piston (411) to its original position due to the pressure inside the cylinder (412), and the screen part (30) connected to the connector (45) that receives the restoring force of the piston (411) receives a force that moves it away from the rolling drive part (20).

[0061] Accordingly, the above-described tension maintaining part (40) is composed of a pressure cylinder (41), a wire (44), a first pulley part (42), a second pulley part (43), and a connector (45), and through the above-described operation process, the screen part (30) can always be kept taut.

[0062] Referring to FIG. 13, the rolling frame (24) may include a rolling frame insertion groove (241) in the longitudinal direction on its outer surface, and by inserting and joining one end of the light-blocking screen (31) through the rolling frame insertion groove (241), which is formed with a narrow opening and a wide interior, the light-blocking screen (31) can be wound on the outer surface as the rolling frame (24) rotates.

[0063] Referring to FIG. 14, the guiding bar (32) may include a guiding bar insertion groove (321) in the longitudinal direction, and the opening is formed narrow and the interior is formed wide so that a light-blocking screen (31) can be fitted and connected, and both sides of the guiding bar (32) are connected to the connecting body (45) of the tension maintaining part (40).

[0064] Referring to FIG. 15, the screen portion (30) of the light-blocking electric screen (1) may further include a sagging prevention member (311).

[0065] The anti-sagging member (311) can be formed in a bar shape and can be installed at regular intervals on the shading screen (31) and can move along the inside of the rail hole (11) formed in the side rail frame (10) together with the shading screen (31), and can also be wound on the rolling frame (24) together with the shading screen (31).

[0066] These anti-sagging members (311) can be positioned at regular intervals on the shading screen (31) as the shading screen (31) is wound and unwound according to the rotation of the rolling frame (24), and can perform the role of preventing sagging of the shading screen (31), which is prone to folding or crumpling.

[0068] Although embodiments of the present invention have been described above with reference to the attached drawings, those skilled in the art will understand that the present invention can be implemented in other specific forms without changing the technical concept or essential features of the invention. Accordingly, the embodiments described above are illustrative in all respects and are not restrictive. Explanation of the symbols
