[0033] Hereinafter, a sunshade damage prevention device according to a preferred embodiment of the present invention will be described in detail with reference to the attached drawings.

[0034] FIG. 1 is an exploded perspective view illustrating an awning damage prevention device according to an embodiment of the present invention, FIG. 2 is a cross-sectional view illustrating FIG. 1 combined, FIG. 3 is an exemplary cross-sectional view illustrating the operating state of the main magnet part of the awning damage prevention device according to an embodiment of the present invention, and FIG. 4 is an exemplary cross-sectional view illustrating the operating state of the main magnet part and the sub magnet part of the awning damage prevention device according to an embodiment of the present invention.

[0035] As illustrated in FIG. 1, the sunshade damage prevention device (10) according to an embodiment of the present invention includes a spiral section (100), a main magnet section (200), and a sub magnet section (300).

[0036] More specifically, as illustrated in FIG. 1 and FIG. 2, the sunshade damage prevention device (10) according to an embodiment of the present invention comprises a front bar (11) connected to the end of a folding link and a fixing bracket (12) arranged in a plurality on one side of the front bar to connect a tent (13) to the front bar, and comprises a threaded portion (100) fastened to the fixing bracket, a main magnet portion (200) having a magnet body (210) seated on the threaded portion, a receiving hole (220) communicating with the magnet body and the threaded portion, and an elastic member (230) inserted into the receiving hole, and a sub magnet portion (300) arranged on the tent in correspondence with the magnet portion and attached to and detached from the magnet portion by gas pressure.

[0037] Here, the awning damage prevention device (10) according to an embodiment of the present invention is intended to prevent damage to the front bar (11), the tent (13), and the folding link connected to the front bar (11) as the tent is lifted by applying external pressure and wind pressure to the tent provided in the awning.

[0038] In addition, the front bar (11) has a guide groove formed on its lower surface to allow the folding link to move back and forth horizontally, and can be equipped with a main magnet part (200) and a sub magnet part (300) on its upper surface.

[0039] A plurality of fixed brackets (12) are arranged along the longitudinal direction of the front bar (11) on one surface to connect the spiral section (100), and the main magnet section (200) is seated on the spiral section (100) to enable linear reciprocating movement in the up and down direction.

[0040] As illustrated in FIGS. 1 and 2, in the sunshade damage prevention device (10) according to an embodiment of the present invention, the spiral portion (100) is fastened to a fixing bracket (12) and further includes a male screw (110) and a female screw (120).

[0041] The male screw (110) is extended in the longitudinal direction and forms a spiral on its outer surface, so that one end is spirally coupled to the inside of the fixing bracket (12). The other end of the male screw (110) is positioned so that the lower surface of the magnet body (210) is seated thereon.

[0042] The female screw (120) is spirally coupled to the outer surface of the male screw (110), thereby enabling the male screw (110) to be securely positioned on the fixing bracket (12).

[0043] As illustrated in FIGS. 1 and 2, in a sunshade damage prevention device (10) according to an embodiment of the present invention, the main magnet part (200) has a magnet body (210) seated on a spiral part (100), and has a receiving hole (220) communicating with the magnet body (210) and the spiral part (100), and an elastic member (230) inserted into the receiving hole (220).

[0044] The magnet body (210) is a permanent magnet that generates magnetic force and is seated on the other side of the male screw (110) by means of the elastic member (230) and the upper fixing pin (260) described later. In order to prevent the upper fixing pin (260) from being seated on one side of the magnet body (210) and detached, it is preferable to form a step that is lower in height from one side corresponding to the position of the receiving hole (220).

[0045] The receiving hole (220) is formed by penetrating the magnet body (210) and the spiral portion (100) to communicate with each other, and an elastic member (230) is inserted to connect the magnet body (210) and the spiral portion (100) to each other by the elastic member (230).

[0046] One side of the elastic member (230) passes through one side of the male screw (110) and is located inside the fixed bracket (12), and the other side is located on one side of the main body (210), so that gas is collected by external pressure and wind pressure applied to the tent (13), and thus expands or contracts to its original length in response to the phenomenon of the tent (13) being lifted.

[0047] Referring to FIGS. 1 and 2, the main magnet part (200) further includes a washer (240), a lower fixing pin (250), and an upper fixing pin (260).

[0048] A washer (240) is provided inside the fixing bracket (12) and is coupled to one side of the spiral portion (100). This washer (240) is formed in a flat disc shape and can be bent along the edge to form an L-shape in the cross-section of the edge. This serves to prevent the lower fixing pin (250), which will be described later, from detaching from the disc after it is seated on the lower part of the washer (240).

[0049] The lower fixing pin (250) is a pin that is fastened to one side of the elastic member (230) and seated on one surface of the washer (240). As a result, one side of the elastic member (230) passes through one side of the male screw (110) and is positioned inside the fixing bracket (12), thereby preventing the elastic member (230) from being detached from one side of the male screw (110).

[0050] The upper fixing pin (260) is a pin that is fastened to the other side of the elastic member (230) and rests on one side of the magnet body (210). As a result, the other side of the elastic member (230) is firmly positioned on one side of the magnet body (210), thereby connecting the male screw (110), the magnet body (210), and the elastic member (230) to each other.

[0051] Meanwhile, as illustrated in FIGS. 1 and 2, the main magnet part (200) of the sunshade damage prevention device (10) according to an embodiment of the present invention may further include a concave part (270).

[0052] The concave portion (270) is formed as a concave female body on one side of the magnet body (210), and serves to allow the female body formed as a convex portion (310) of the sub-magnet portion (300) described later to be firmly seated. As a result, the sub-magnet portion (300) is guided to be seated after being separated from one side of the magnet body (210), thereby preventing the tent (13) from completely detaching from the front bar (11).

[0053] As illustrated in FIGS. 2 and 4, in the awning damage prevention device (10) according to an embodiment of the present invention, the sub-magnet part (300) is a sub-magnet that is placed on the tent (13) corresponding to the magnet part (100) and is attached to and detached from the magnet part (100) by the pressure of gas. The sub-magnet of the sub-magnet part (300) may be made of a metal that can be attached by the magnetic force of the magnet part (100), in addition to a permanent magnet.

[0054] This sub-magnetic part (300) is formed with a convex part (310) on one side and serves to be firmly seated in the concave part (270).

[0055] That is, the higher the pressure of the gas applied to the tent (13), the stronger the lifting force of the tent (13), so a passage must be secured to quickly discharge the gas to prevent damage to the tent (13), the front bar (11), and the folding link. To this end, the sub-magnetic part (300) is separated from the magnetic part (200) to discharge the gas to the outside, thereby lowering the pressure of the gas applied to the tent (13).

[0056] Additionally, as shown in FIGS. 1 and 4, the sub-magnetic part (300) further includes a support plate (320).

[0057] The support plate (320) is formed with a length corresponding to the length of the front bar (11) and is placed on the upper surface of the tent (13) and coupled to a sub-magnet placed on the lower surface of the tent (13) so that the sub-magnet can be firmly positioned on the lower surface of the tent (13).

[0058] And, by reducing the flapping of the tent (13) due to external pressure and wind pressure, and preventing the sub-magnet from detaching from the magnet body (210) when the sub-magnet is separated from the magnet body (210) due to excessive flapping of the tent (13), the pressure of the gas applied to the tent (13) is reduced so that it can be settled on one side of the magnet body (210).

[0059] Hereinafter, the process of operating the sunshade damage prevention device according to the embodiment of the present invention through each configuration is described.

[0060] The sunshade damage prevention device (10) according to an embodiment of the present invention is installed so that a tent (13) is connected to a front bar (11) and can be extended.

[0061] At this time, when the tent (13) is lifted by the pressure of the gas, the elastic member (230) is extended so that the magnet body (210) separates from the spiral part (100) and serves to lower the pressure of the gas.

[0062] For example, if an awning is installed to extend the tent, wind may blow up and down the tent due to the influence of the natural environment, causing the tent to flap and be lifted. If the tent is exposed for a long time to an environment where the front bar and folding links shake due to the flapping of the tent, the tent may stretch or tear, and the folding links connected to the front bar may bend or the shape of the front bar may be deformed and damaged.

[0063] To improve this problem, as shown in FIGS. 2 and 3, when gas is gathered in the tent (13) and lifted, the magnet body (210) moves upward in response to the pressure of the gas, and the elastic member (230) expands in response to the distance of movement of the magnet body (210).

[0064] At this time, the magnet body (210) is spaced apart from the other side of the male screw (110) constituting the spiral portion (100) to form a space. Through this space, the gas accumulated in the tent (13) escapes to the outside, increasing the volume of the gas and reducing the pressure.

[0065] Additionally, in the case of the space between the other side of the male screw (110) and the magnet body (210), the volume increases due to the movement of the gas and the density of the gas decreases, so the gas located in other areas of the tent (13) moves to the part with increased volume and escapes to the outside.

[0066] Next, as shown in FIGS. 2 and 3, when the pressure of the gas is lowered, the elastic member (230) contracts and serves to lower the magnet body (210) so that it can be seated on the spiral portion (100).

[0067] To explain further, the pressure of the tent (13) is lowered by the movement of the gas, and the force that moved the magnet body (210) upward is reduced, causing the elastic member (230) to contract and pull the magnet body (210) down so that it settles on the other side of the male screw (110). Then, as the magnet body (210) descends, the tent (13) also returns to its original position, serving to block sunlight and protect against rain.

[0068] At this time, as shown in FIGS. 3 and 4, when the pressure of the gas increases, it is desirable to lower the pressure of the gas by separating the sub-magnet part (300) seated on the magnet body (210) to increase the area through which the gas passes.

[0069] For example, if stronger winds, such as a typhoon, blow and the pressure of the gas increases further before the awning is rolled up, the gas accumulated in the awning (13) increases more than the density of the gas escaping into the space formed by the magnet body (210) being separated from the other side of the male screw (110) by the lifting of the awning as described above, then the awning (13) is lifted further.

[0070] As a result, the sub-magnet part (300) mounted on one side of the magnet body (210) is separated in response to the movement of the tent (13), thereby forming a space between the magnet body (210) and the sub-magnet part (300).

[0071] At this time, the gas collected in the tent (13) moves simultaneously to the spaced-apart space between the male screw (110) and the magnet body (210) and the spaced-apart space between the magnet body (210) and the sub-magnet part (300) and exits to the outside, thereby reducing the pressure of the gas collected in the tent (13) so that the convex part (310) of the sub-magnet part (300) settles into the concave part (270) of the magnet body (210).

[0072] The sunshade damage prevention device (10) according to the embodiment of the present invention is a device that moves the magnet body (210) in a linear reciprocating motion at least once in response to the pressure of the gas, and allows at least one sub-magnet part (200) to be attached to and detached from the magnet body (210).

[0073] That is, since external pressure and wind pressure are not applied to the tent (13) in a constant manner but are applied in various arbitrary directions, when the number of magnet bodies (210) placed on the tent (13) is from the first to the nth depending on the degree of gas pressure, the first magnet body (210) or one or more of the second to nth magnet bodies (210) are separated from the male screw (110) and then seated on the other side of the male screw (110), thereby preventing the tent (13) from being torn or the corresponding magnet body (210) from being seated on another male screw (110).

[0074] In addition, the sub-magnet part (200) is identical to the magnet body (210) described above, so it is replaced by the description of the magnet body (210).

[0075] As explained above, the detailed description of the present invention describes preferred embodiments of the invention; however, this is merely an illustrative description of the best embodiments of the invention and is not intended to limit the invention. Furthermore, it is obvious that anyone skilled in the art to which the present invention pertains can make various modifications and imitations within the scope of the technical concept of the present invention without departing from it.

[0076] Accordingly, the scope of the present invention is not limited to the embodiments described above but may be implemented in various forms of embodiments within the scope of the appended claims. Furthermore, it is deemed that the scope of the claims of the present invention includes various modifications that are possible by anyone with ordinary knowledge in the technical field to which the invention belongs, without departing from the essence of the invention claimed in the claims.
