1 is a schematic front sectional view showing a state of a bottom-up blind 10 according to an embodiment.

1, the bottom-up blind 10 is disposed below a light-shielding object W such as a window or a door so as to prevent the inside of the light-shielding film 100 from being moved upward from a lower portion of the light- do. When the bottom-up blind 10 is disposed in a building or a single-storey building of various buildings such as an apartment or a building in which a layer of the same height is formed around the building, the light-shielding film 100 is raised and shielded by an external field of view, So that the sunlight can effectively prevent the room from being seen while being lighted into the room.

Here, the light-shielding film 100 can be wound in a combination blind, a roll blind, or the like, and may be all blinds for shading, and is wound around a shaft 210 to be described later to block the object W to be shielded.

Further, the bottom-up blind can be placed not only in the room but also outdoors. When the bottom-up blind is placed outdoors, the light-shielding film can be blocked before the light enters the room, so it may be possible to remove the heat coming into the room.

The bottom-up blind 10 includes the light-shielding film 100, the lower body 200, the adjusting assembly 300, the upper body 400, and the fixing assembly 500A.

2 is a front cross-sectional view schematically showing a state of a lower body 200 of a bottom-up blind 10 according to an embodiment.

Referring to FIG. 2, the lower body 200 is formed in an empty shape to receive the shaft 210 therein. For example, the lower body 200 can receive the shaft 210 in a structure in which the shaft 210 is constantly subjected to rotational force in one direction by a spring means (not shown) such as a spring spring at one end.

Since the shaft 210 receives the rotational force in one direction by the spring means while the light shielding film 100 is unwound, the shaft 210 can be wound by the restoring force of the spring means when the light shielding film 100 is wound again. The light shielding film 100 can be wound around the outer circumferential surface of the shaft 210.

The lower body 200 is formed with an access hole 220 through which the light shielding film 100 can enter and exit.

The lower body 200 may be disposed below the object W to be shielded. For example, the lower body 200 may be disposed such that the bottom surface of the object W is parallel to the longitudinal direction of the lower body 200. The lower body 200 may be disposed on the light shielding object W and fixed through the adjustment assembly 300. [

For example, the adjustment assembly 300 includes an adjustment foot 310 and a lower elastic member 320.

The adjustable foot 310 is coupled to one end of the lower body 200 and is fixed by abutting against the light shielding object W. [ For example, the adjustable foot 310 may protrude from one end of the lower body 200 and may be fixed by abutting against the light shielding object W. The adjusting foot 310 may be formed of a material having high frictional resistance such as rubber, silicone or the like and capable of being stretchable or elastically deformable. In addition, the adjustment foot 310 may be coupled to the inside of the lower body 200 such that a part of the adjustment foot 310 has a small diameter in a cross section.

The lower elastic member 320 is received at one end of the lower body 200 to elastically support the adjustment foot 310 in the longitudinal direction of the lower body 200. For example, the lower elastic member 320 may be a spring.

Accordingly, when the control foot 310 is pressed and moved to the inside of the lower body 200, the lower elastic member 320 is compressed, and force is applied to the control foot 310 to protrude to the outside by the restoring force, (W).

The side surface of the object W to be shielded may be a window frame or a door frame, and may be a window frame or a door frame of an indoor or outdoor.

The adjustment assembly 300 may further include a screw adjusting foot 330 coupled to the other end of the lower body 200.

The screw adjusting foot 330 may be formed inside the lower body 200 such that a portion of the screw adjusting foot 330 has a small diameter. The screw 331 is formed on a part or the whole of the outer circumferential surface of the portion where the cross section of the screw adjusting foot 330 has a small diameter. The screw adjusting foot 330 is formed with an adjusting groove 230 formed with a female screw corresponding to the thread 331 of the screw adjusting foot 330 formed at one end of the lower body 200. The screw adjusting foot 330 is fixed by abutting against the light shielding object W by adjusting the depth of coupling with the adjusting groove 230 when the lower body 200 is coupled. The surface of the screw adjusting foot 330, which is in contact with the light-shielding object W, is formed of a material which is high in frictional resistance, such as rubber, silicone or the like, and can be stretchable or elastically deformable.

The bottom-up blind 10 according to one embodiment shows that the adjusting feet 310 and the screw adjusting feet 330 are coupled to both ends of the lower body 200, but the present invention is not limited thereto. For example, the adjustment foot 310 may be provided at both ends of the lower body 200, and the screw control foot 330 may be provided at both ends of the lower body 200. Also, it may be possible to provide the adjusting foot 310 or the screw adjusting foot 330 only at one end of the lower body 200.

The lower body 200 may be coupled to a window frame or a door frame of a light-shielding object W by a coupling method such as interference fit or by screws or an adhesive, but in this case, the light-shielding object W is damaged. However, the bottom-up blind 10 according to the embodiment can be fixed to the lower side surface of the light-shielding object W by protruding the adjustment assembly 300 from the lower body 200, and can be coupled without damaging.

3 is a front sectional view schematically showing a state of an upper body 400 of a bottom-up blind 10 according to an embodiment.

Referring to FIG. 3, the upper body 400 is coupled to the other end of the light shielding film 100 and is provided on the upper portion of the lower body 200. The other end of the light shielding film 100 wound on the shaft 210 is moved in accordance with the upward and downward movement of the upper body 400 to adjust the length of the light shielding film 100 from the lower side of the light shielding object W, Some or all of them can be blocked.

The fixing assembly 500A fixes the position of the upper body 400 with respect to the object W to be shielded. For example, the fixing assembly 500A protrudes from the upper body 400 to extend the length of the upper body 400 and fix the upper body 400 to the side of the light-shielding object W.

The fixing assembly 500A may include a fixing portion 510A and a top elastic member 520A.

The fixing portion 510A is coupled to one end or both ends of the upper body 400. [ For example, the fixing portion 510A has a predetermined groove formed at both ends of the upper body 400, and is inserted into the groove. The fixing portions 510A inserted at both ends of the upper body 400 may be movable in the longitudinal direction. When the fixing part 510A protrudes in the longitudinal direction of the upper body 400, the fixing part 510A can be fixed to the side of the light blocking object W by the frictional force by extending the length of the upper body 400. [ On the contrary, when the fixing portion 510A is inserted in the longitudinal direction of the upper body 400, the contact with the light-shielding object W is released so that the upper body 400 can be moved.

The fixing portion 510A is formed of a material having high frictional force such as rubber or silicone. Further, the fixing portion 510A may be formed of an elastic material. When the fixing portion 510A comes into contact with the object W to be shielded, when the contact is released after being compressed, it can be restored to its original state.

The upper elastic member 520A may apply an elastic force to the fixing portion 510A in the longitudinal direction of the upper body 400. [ For example, the upper elastic member 520A may be inserted into the groove into which the fixing portion 510A is inserted, so that the upper elastic member 520A may exert an elastic force so as to protrude in the longitudinal direction of the upper body 400. [ The upper elastic member 520A may be a material having an elastic force.

Accordingly, the bottom-up blind 10 can be moved up and down to a position where the user can press the fixing part 510A to shield the upper body 400 and adjust the light blocking film 100 to cover part or all of the light blocking object W This is possible. In addition, when the user does not press the fixing portion 510A, the bottom-up blind 10 can be fixed to the light-shielding object W by protruding the fixing portion 510A in the longitudinal direction of the upper body 400. [

The fixing assembly 500A may further include an adjusting wire 530A and a tension adjusting portion 540A.

The adjusting wire 530A is connected to the fixing portion 510A. For example, the adjusting wires 530A can connect the fixing portions 530A disposed at both ends of the upper body 400 to each other. The adjusting wire 530A connects the fixing portions 510A at both ends thereof, and maintains a constant tension.

The tension adjusting portion 540A is provided at one side of the adjusting wire 530A. For example, the tension adjusting unit 540A may be provided so as to abut on one side of the adjusting wire 530A. In addition, the tension adjusting unit 540A may be inserted into the upper body 400 while being protruded from the upper body 400 at regular intervals.

The tension adjusting portion 540A adjusts the tension of the adjusting wire 530A so as to move the fixing portion 510A to the inside of the upper body 400. [ For example, the tension adjusting portion 540A can adjust the tension of the adjusting wire 530A by applying pressure to the adjusting wire 530A in the vertical direction of the adjusting wire 530A. The tension adjusting unit 540A exerts a pressure in a vertical direction of the adjusting wire 530A when a pressure is applied to a portion protruding at a predetermined distance from the upper portion of the upper body 400. [ The adjusting wire 530A is moved along the tension adjusting portion 540A so that both ends are pulled inward in the longitudinal direction of the upper body 400 and the fixing portion 510A connected to both ends of the adjusting wire 530A And is moved inward in the longitudinal direction of the upper body 400. The tension adjusting portion 540A can insert the fixing portion 510A into the upper body 400 with a simple operation.

The bottom-up blind 10 applies pressure to the tension adjusting portion 540A and inserts the fixing portion 510A into the upper body 400. Thereafter, the upper body 400 is moved up and down in the vertical direction of the light-shielding object W to a desired light-shielding height. When the pressure applied to the tension adjusting part 540A is removed to fix the moved upper body 400, the fixing part 510A protrudes from the upper body 400 and is fixed to the object W to be shielded.

Hereinafter, a bottom-up blind 20 according to another embodiment will be described with reference to FIG. 4 according to another embodiment of the present invention is different from the above embodiment in that the shape of the fixing portion 510B is cylindrical and the rotation wheel 550B is added, And reference numerals and explanations of the above-described embodiments will be used for the same components.

4 is a front cross-sectional view schematically showing an upper body 400 of a bottom-up blind 20 according to another embodiment.

4, the fixing assembly 500B of the bottom-up blind 20 includes a fixing portion 510B, a top elastic member 520A, an adjusting wire 530A, a tension adjusting portion 540A, and a rotating wheel 550B .

The fixing portion 510B can form a receiving space therein. For example, the fixing portion 510B may be formed in a cylindrical shape with one side opened. The fixed portion 510B can contact the light shielding object W with the cylindrical open end thereof to fix the upper body 400 to the light shielding object W. [

The upper elastic member 520A, the adjusting wire 530A and the tension adjusting unit 540A have the same configurations as those of the bottom-up blind 10 according to the embodiment described with reference to Figs. 1 to 3, and thus description thereof will be omitted.

The rotary wheel 550B may be provided inside the fixing portion 510B. For example, the rotary wheel 550B is provided inside the cylindrical fixing portion 510B and can be fixed and rotated by an axis 550B extending from the inside of the upper body 400. [

The rotary wheel 550B rotates in contact with the light shielding object W when the fixing portion 510B moves inward of the upper body 400 by the adjusting wire 530A. For example, the spinning wheel 550B may be a spherical or disk-shaped rotatable shape. Further, the rotation direction of the rotary wheel 550B may have a rotation direction in which the object moves upward and downward. When the adjustment wire 510A moves inward of the upper body 400, the rotary wheel 550B can rotate in the vertical direction against the light-shielding object W. [ The rotary wheel 550B can assist the movement of the upper body 400 without damaging the upper body 400 and the light shielding object W. [

The upper body 400 can be fixed to the side surface of the light shielding object W by the fixing portion 510B projected by the elastic force of the upper elastic member 520A. At this time, when pressure is applied to the tension adjusting unit 540A, tensile force is applied to the adjusting wire 530A, and the fixing unit 510B is moved to the inside of the upper body 400 to be fixed with the light shielding object W have. The rotary wheel 550B comes into contact with the light shielding object W and the rotary wheel 550B comes into contact with the upper body 400 when the fixing body 510B is moved to the inside of the upper body 400. [ As shown in Fig.

Hereinafter, a bottom-up blind 30 according to another embodiment will be described with reference to FIG. The bottom-up blind 30 of FIG. 5 according to another embodiment of the present invention has a configuration of a connecting bar 530C and a hinge connecting portion 540C provided in a hinged bar shape in a fixing assembly, The differences are mainly described, and the same reference numerals and explanations of the embodiments described in Figs. 1 to 3 are used for the same components.

5 according to another embodiment includes a light shielding film 100, a lower body 200, an adjusting assembly 300, an upper body 400, and a fixing assembly 500C. The lower shield 400 includes a light shielding film 100, The configuration of the control assembly 200 and the control assembly 300 includes the same components as those of the embodiment described with reference to Figs. 1 to 3, and a description thereof will be omitted.

5 is a front sectional view schematically showing a state of the upper body of the bottom-up blind 30 according to another embodiment.

5, the fixing assembly 500C of the bottom-up blind 30 according to another embodiment includes a fixing portion 510C, a top elastic member 520C, a connecting bar 530C and a hinge connecting portion 540C .

The fixing portion 510C is partially inserted into both ends of the upper body 400 so as to protrude therefrom. The fixing portion 510C may be movable in the longitudinal direction of the upper body 400. [ The fixing portion 510C is formed of a material having high frictional force such as rubber or silicone. Further, the fixing portion 510C may be formed of an elastic material. When the fixing portion 510C comes into contact with the object W to be shielded, it can be restored to its original state when the contact is released after being compressed.

The fixing portion 510C is formed with a pushing protrusion 511C protruding from a surface of the fixing portion 510C which is inserted into the upper body 400. [ The hook portion 511C may have a shape extending through the upper elastic member 520C and extending a certain length to the inside of the upper body 400. [

The upper elastic member 520C can apply an elastic force to the fixing portion 510C in the longitudinal direction of the upper body 400. [ For example, the upper elastic member 520C may be inserted into the groove into which the fixing portion 510C is inserted, so that the upper elastic member 520C may exert an elastic force to be inserted in the longitudinal direction of the upper body 400C. The upper elastic member 520C may be an elastic material such as a spring.

The connection bar 530C may have a slit 531C formed at one end thereof in the longitudinal direction and slits 531C may be hingedly connected to both sides of the upper body 400. [ For example, the connection bar 530C may have a bar shape having a slit 531C formed at one end thereof in the longitudinal direction. The upper body 400 may be provided with a cylindrical slit connection part 410 connected to the slit 531C. The connection bar 530C can be connected by inserting the slit connection part 410 into the slit 531C. The length of the slit 531C is formed to be large enough to secure the moving distance of the connecting bar 530C when the connecting bar 530C moves up and down as described later.

The hinge connection part 540C can connect the other end of the pair of connection bars 530C in a hinge form.

The connection bar 530C may have a shape in which the initial state is connected to the upper body 400 in a triangular shape. When the hinge connection portion 540C moves to the upper body 400, the pair of connection bars 530C slides the slit 531C to the slit connection portion 410 and one end of the connection bar 530C slides on the upper body 400, As shown in Fig. Therefore, the pair of connection bars 530C can move the fixing portion 510C to the outside in the longitudinal direction of the upper body 400 by pushing the pushing portion 511C of the fixing portion 510C.

However, the present invention is not limited thereto, and an elliptical hole may be formed in one of the connecting bars 530C connected to the hinge connecting part 540C to guide the movement of the connecting bar 530C. In this case, one ends of the connecting bar 530C may be fixed to the upper body 400 and the slit 531C may be omitted.

The hinge connection portion 540C may include a hinge fixing portion 541C for fixing the hinge connection portion 540C to the upper body 400 when the fixing portion 510C contacts the side surface of the light blocking object W. [ The hinged portion 541C may be in the shape of a magnet provided on the upper body 400 corresponding to one side of the hinge connection portion 540C. The hinged portion 541C can be detached and attached to the upper body by a magnetic force.
