The difference in height between the 3rd-1 rotary frame (166a) and the 3rd-2 rotary frame (166b) forms a gap between the 2nd sunshade (162) and the 3rd sunshade (163), introducing wind from the outside of the sunshade member (160).

[0133] The 4th rotary frame (167) may be fixed to the other end of the 3rd sunshade (163), and may be rotatably coupled to the 1st rotary bracket (151).

[0134] Referring back to FIG. 1, the deployment control member (170) may be installed to adjust the unfolding position of the sunshade member (160), and to adjust the interval at which the sunshade member (160) is unfolded.

[0135] FIG. 8 shows the deployment control member (170) in more detail.

[0136] FIG. 8 is a view showing a deployment control member (170) according to an embodiment of the present invention.

[0137] Referring to FIG. 8, the deployment control member (170) may comprise a 1st wire (172) and a 2nd wire (173).

[0138] The 1st wire (172) may have one end fixed to the 1st rotary frame (164) and the other end fixed to the turnbuckle (171). Here, the turnbuckle (171) refers to a mechanism for adjusting the length of a support bar or a support wire rope. The 1st wire (172) tensions the deployed sunshade member (160), thereby stably maintaining the deployed state of the sunshade member (160). In addition, the binding structure of the 1st wire (172) and the 2nd wire (173) is useful to maintain stability against strong wind.

[0139] The 2nd wire (173) may pass through the multiple fixing parts (143), with one end fixed to the turnbuckle (171) and the other end fixed to the 4th rotary frame (167). The turnbuckle (171) can adjust the lengths of the 1st wire (172) and the 2nd wire (173), as well as release the 1st wire (172) from the turnbuckle 171 to fold the sunshade member (160).

[0140] That is, the sunshade member (160) can be easily folded by releasing the 1st wire (172) or the 2nd wire (173) connected to the turnbuckle (171).

[0141] In addition, the deployment control member (170) may further comprise a 3rd wire (174).

[0142] The 3rd wire (174) connects one end of the 1st wire (172) and the other end of the 2nd wire (173), and may be fixed to the 1st rotary frame (164), the 2nd rotary frame (165), and the 3rd rotary frame (166), and the 4th rotary frame (167).

[0143] In addition, the deployment control member (170) may be made of a wire having sufficient strength to support the weight of the sunshade member (160).

[0144] In addition, the deployment control member (170) may further comprise an elastic adjustment member (not shown). The elastic adjustment member may be provided between the 2nd wire (173) and the 3rd wire (174). The elastic control member normally applies a force in the folding direction of the sunshade member (160), and when the user combines the 1st wire (172) with the turnbuckle (171), the elastic force is balanced so that the sunshade member (160) can be maintained in an unfolded state. By being provided with the elastic adjustment member, the sunshade member (160) can be automatically folded as soon as the connection between the 1st wire (172) and the turnbuckle (171) is released.

[0145] In addition, the deployment control member (170) may comprise a gas spring (not shown). The gas spring may be provided between the 2nd wire (173) and the 3rd wire (174). Since the gas spring is a conventional one that reciprocates the piston rod by high-pressure gas, a detailed description thereof will be omitted. The gas spring may adjust the height of the 3rd sunshade (163) connected to the 3rd wire (174).

[0146] That is, by lowering the gas spring, the user can lower the height of the 3rd sunshade (163), and accordingly lower the height at which the 1st sunshade (161) and the 2nd sunshade (162) are deployed. By being provided with the gas spring, the angle variable multi-stage sunshade device (100) according to the present invention can deploy the sunshade member (160) at a low position to block the sunlight in the morning or evening when the sun is low, and at a high position to block the sunlight during lunchtime when the sun is high.

[0147] Referring back to FIG. 1, the angle variable multi-stage sunshade device (100) according to an embodiment of the present invention may further comprise a fence member (180).

[0148] The fence member (180) may be installed along the circumference of the baseplate member (130). The fence member (180) can be additionally installed and used for the convenience of the user, and may be excluded as needed as shown in FIG. 10.

[0149] FIG. 9 is a view showing the folded state of the sunshade in the angle variable multi-stage sunshade device (100) according to an embodiment of the present invention.

[0150] As shown in FIG. 9, the sunshade member (160) may be easily folded by releasing the 1st wire (172) or the 2nd wire (173) connected to the turnbuckle (171).

[0151] When the 1st wire (172) or the 2nd wire (173) is released from the turnbuckle (171), the sunshade member (160) can freely rotate around the rotary support member (150), and accordingly, the 1st rotary frame (164), the 2nd rotary frame (165), the 3rd rotary frame (166), and the 4th rotary frame (167) can be sequentially folded.

[0152] Hereinafter, the structure of the angle variable multi-stage sunshade device (100) according to the present invention and an operation related thereto will be described with reference to FIGS. 1 to 12.

[0153] First, referring to FIG. 1, a base member (110) may be provided on the ground. A rotary frame member (140) and a baseplate member (130) may also be provided along the support member (120) seated at a predetermined distance from the top end of the base member (110). The rotary support member (150) may be fixed to the rotary frame member (140), and a sunshade member (160) may be rotationally coupled to the rotary support member (150). A deployment control member (170) may be connected to the rotary frame member (140) and the sunshade member (160).

[0154] The user may sit on the baseplate member (130) and take a break. The sunshade member (160) can be opened and closed by adjusting the deployment control member (170). When the 1st wire (172) of the deployment control member (170) is pulled and coupled to the turnbuckle (171), the deployment control member (170) is tightly fixed and the sunshade member (160) fixed to the deployment control member (170) can also be fully deployed. The 1st wire (172) tensions the deployed sunshade member (160), thereby stably maintaining the deployed state of the sunshade member (160). In addition, the angle and height of the sunshade member (160) can be adjusted little by little by rotating the center of the turnbuckle (171). When removing the sunshade member (160), if the coupling between the turnbuckle (171) and the 1st wire (172) or the 2nd wire (173) is released, the sunshade member (160) freely rotates around the rotary support member (150), and as shown in FIG. 9, the rotary frames (164, 165, 166, 167) of the sunshade member (160) are gathered to one side, making it easy to fold the sunshade member (160).

[0155] In addition, the deployment control member (170) has an elastic adjustment member to apply a force in the direction of folding the sunshade member (160) in usual times. When the user combines the 1st wire (172) with the turnbuckle 1(71), the elastic force is balanced so that the sunshade member (160) can be maintained in an unfolded state. By being provided with the elastic adjustment member, the sunshade member (160) can be automatically folded as soon as the connection between the 1st wire (172) and the turnbuckle 171 is released.

[0156] In addition, the deployment control member (170) may have a gas spring to adjust the height of the sunshade member (160). When the user lowers the gas spring, the height of the 3rd sunshade (163) is lowered, and accordingly, the height at which the 1st sunshade (161) and the 2nd sunshade (162) are deployed can be lowered. By being provided with the gas spring, the angle variable multi-stage sunshade device (100) according to the present invention can unfold the sunshade member (160) at a low position to block the sunlight in the morning or evening when the sun is low, and at a high position to block the sunlight during lunchtime when the sun is high.

[0157] In addition, the direction of the sunshade member (160) can be changed easily according to the user's convenience by rotating the rotary frame member (140 When an external force is applied while the rotary frame member (140 is seated on the roller (125) of the support member (120), the rotary frame member (140 may rotate along the path guided by the roller (125). At this time, by being alternately provided with the 1st support (121) having the roller (125) in the direction to one side and the 2nd support (122) having the roller (125) in the upward direction, the support member (120) may prevent movement and shaking of the rotary frame member (140), thereby making it rotate in a fixed position.

[0158] In addition, when the rotary frame member (140 rotates, the 2nd wire (173), wound along the circumference of the rotary frame member (140, rotates together to turn the sunshade member (160) in a desired direction without being limited by the location of the deployment control member (170).

[0159] In addition, a fence member (180) can be installed and used according to the user's convenience.

[0160] As described above, according to an embodiment of the present invention, the use of a rotary frame member allows the user to easily turn the sunshade in a desired direction.

[0161] In addition, according to the present invention, by using the turnbuckle, it is possible to easily adjust the angle of the sunshade and fold the sunshade.

[0162] In addition, according to the present invention, by using different types of support members at the same time, it is possible to prevent the center movement and shaking of the sunshade during rotation of the sunshade, and to turn the sunshade at a fixed position.

[0163] In addition, according to the present invention, by using a wire, it is possible to stably maintain the sunshade deployed state.

[0173] As shown in FIG. 16 to FIG. 20, the sunshade member (1130) consists of: a 1st sunshade unit (1131) that is rotatably coupled to the support member (1110), and formed in a radial arc shape to form a shading space; a 2nd sunshade unit (1135) that is rotatably coupled to the support member (1110), and formed in a radial arc shape to form a shading space; and a 3rd sunshade unit (1141) that is rotatably coupled to the support member (1110), and formed in a radial arc shape to form a shading space.

[0174] The sunshade members (1130) are formed in a cone shape, respectively, and installed so that the user can selectively deploy (expand and fold) the sunshade units (131, 135, 141).

[0175] A 1st sunshade frame (1132) for fixing one end of the 1st sunshade (1134) is fixed to the 1st sunshade unit (1131), a 1st rotary frame (1133) coupled to the rotary bracket (1114) is integrally formed on both sides of the 1st sunshade frame (1132), respectively, and the 1st rotary frame (1133) is rotatably coupled to the rotary bracket (1114).

[0176] The 1st sunshade frame (1132) is provided with a 1st sunshade (1134) in the shape of a headband.

[0177] In addition, the 2nd sunshade unit (1135) is provided with a 2nd sunshade frame (1136) for fixing one end of the 2nd sunshade (140), and one end of the 1st sunshade (1134) and one end of the 2nd sunshade (1138) are fixed to the 2nd sunshade frame (1136).

[0180] The 2nd sunshade unit (1135) is formed to have a smaller diameter than the 1st sunshade unit (1131) so that the 2nd sunshade unit (1135) can be folded into the 1st sunshade unit (1131).

[0181] The 3rd sunshade unit (1141) comprises a 3rd sunshade frame (1142) for fixing the 3rd sunshade (1145), and a 3rd rotary frame (1144) is installed at both ends of the 3rd sunshade frame (1142), respectively.

[0182] These rotary frames (133, 137, 144) are rotatably coupled to the rotary bracket (1114), respectively.

[0183] The 3rd sunshade unit (1141) is formed to have a smaller diameter than the 2nd sunshade unit (1135) so that it can be folded into the 2nd sunshade unit (1135).

[0184] As shown in FIG. 17 and FIG. 18, the deployment control member (1170), which is to maintain the tension of the unfolded 1st sunshade unit (1131) and 3rd sunshade unit (1141), comprises: a 1st wire (1171) having one end fixed to the 1st sunshade unit (1131) and the other end fixed to the 3rd sunshade unit (1141); a 2nd wire (1172) having both ends fixed to one side of the 1st sunshade unit (1131) and the 3rd sunshade unit (1141), respectively; a 3rd wire (1173) having both ends fixed to the other side of the 1st sunshade unit (1131) and the 3rd sunshade unit (1141), respectively; and a rotary roller (1175) to be rotatably installed on the fixing bracket (1174) installed on the lower side of the 1st sunshade unit (1131)

[0185] One end of the 1st wire (1171) is fixed to the 1st sunshade frame (1132) of the 1st sunshade unit (1131), and the other end of the 1st wire (1171) is fixed to the 3rd sunshade frame (1142) of the 3rd sunshade unit (1141).

[0186] The 1st wire (1171) consists of a short wire (171a) to be installed between the 1st sunshade unit (1131) and the length control member (1176) and a long wire (171b) to be installed between the length control member (1176) and the 3rd sunshade frame (1142).

[0187] One end of the short wire (171a) is connected to the 1st sunshade frame (1132) of the 1st sunshade unit (1131), and the other end of the short wire (171a) is connected to the length control member (1176).

[0188] On the other hand, one end of the long wire (171b) is connected to the length control member (1176), and the other end of the long wire (171b) is connected to the 4th sunshade frame (1144) of the 3rd sunshade unit (1141).

[0189] The 1st wire (1171) keep taut the deployed 1st and 3rd sunshade units (1131, 1141) to stably maintain the deployed state of all of the 1st sunshade unit (1131), 2nd sunshade unit (1135) and 3rd sunshade unit (1141).

[0190] In addition, the length control member (1176) may use a turnbuckle as an example, and may adjust the length of the short wire (171a) and the long wire (171b) as well as release the 1st wire (1171) from the length control member (1176) so that the sunshade member (1130) can be folded.

[0191] That is, the sunshade member (1130) can be easily folded by releasing the short wire (171a) or the long wire (171b) connected to the length control member (1176).

[0192] In addition, the 2nd wire (1172) is installed on one side inside the 1st sunshade unit (1131) and the 3rd sunshade unit (1141), and the 3rd wire (1173) is installed on the other side inside the 1st sunshade unit (1131) and the 3rd sunshade unit (1141).

[0193] These 2nd wire (1172) and 3rd wire (1173) limit the deployment range of the 1st and 3rd sunshade units (1131, 1141).

[0194] That is, the 1st sunshade unit (1131) and the 3rd sunshade unit (1141) are deployed in a limited range of the length of the wires (172, 173) by the 2nd wire (1172) and the 3rd wire (1173).

[0196] The 1st sunshade unit (1131) and the 3rd sunshade unit (1141) stably maintain a state deployed by the 1st wire (1171).

[0197] That is, when the sunshade member (1130) is deployed to a low position, the 1st wire (1171) is installed while being wound around the outer surface of the pair of rotary rollers (1175) so that the sunshade member (1130) will remain unfolded without being rotated arbitrarily by wind or the like.

[0198] This is because the 1st sunshade unit (1131) and the 3rd sunshade unit (1141) are fixed by the 1st wire (1171), respectively, so that the sunshade member (1130) is not rotated by external factors such as wind.

[0199] In addition, when the sunshade member (1130) is deployed to a high position, the 1st wire (1171) moves along the rotary roller (1175) of the 1st wire (1171) while being fixed to both ends of the 1st sunshade unit (1131) and the 3rd sunshade unit (1141) according to the deployment position of the sunshade member (1130)

[0200] On the other hand, since the length control member (1176) is to generate tension by expanding the sunshade member (1130) and adjusting the length of the wire (1171), a bar stopper (not shown) or a rope ratchet that can adjust the length of the wire (1171) as well as turnbuckle can be used.

[0201] FIG. 21 is a single-view drawing showing a folded state of an angle variable multi-stage sunshade device according to a preferred embodiment of the present invention, FIG. 22 is a single-view drawing showing an unfolded state of an angle variable multi-stage sunshade device according to a preferred embodiment of the present invention, FIG. 23 is a single-view drawing showing a state in which an angle variable multi-stage sunshade device is installed according to a preferred embodiment of the present invention, and FIG. 24 is a single-view drawing showing a state in which an angle variable multi-stage sunshade device is tilted to one side according to a preferred embodiment of the present invention.

[0202] As shown in FIG. 21 to FIG. 24, the sunshade member (1130) releases the long wire (171b) of the 1st wire (1171) connected to the length control member (1176), allowing to fold the sunshade member (1130) conveniently.

[0203] When the long wire (171a) is released from the length control member (1176), the 1st sunshade unit (1131), the 2nd sunshade unit (1135), and the 3rd sunshade unit (1141) of the sunshade member (1130) can freely turn around the rotary bracket (1114) so that the 1st sunshade unit (1131) to the 3rd sunshade unit (1141) can be sequentially folded.

[0204] As described above, the invention made by the present inventor has been described in detail according to the above embodiments, but the present invention is not limited to the above embodiments and can be changed in various ways without departing from the gist thereof.
