[0014] However, such sky pagodas cause the following problems.

[0015] (1) When a sky pergola is constructed with an electric ceiling that can be opened and closed, raindrops falling on the roof made of fabric or other materials run down toward the edges and accumulate on the floor, causing inconvenience to pedestrians.

[0016] (2) In particular, raindrops falling on the fabric tend to gather at the edges and fall all at once, so the amount of rainwater that accumulates and falls downwards is large, causing it to fall strongly and splash in all directions or create large puddles.

[0017] (3) Also, if the collected rainwater falls all at once on people entering and leaving the sky pergola, their clothes may get soaked.

[0018] (4) At this time, rainwater collects along the edges of the profiles that make up the ceiling of the sky pergola and falls down when a certain amount of water has accumulated, so even when the rain stops, the collected rainwater can fall down.

[0020] The present invention takes these points into consideration and aims to provide a sky pergola with an enhanced drainage function that allows for safe and convenient use by preventing rainwater collected at the edges of the ceiling from rapidly falling downwards, in a sky pergola configured to automatically fold or unfold a fabric, by mounting a water tray on the lower part of the profile so as to be positioned at the lower ends of both sides of the bar supporting the fabric, and configuring the structure so that rainwater collected in the tray can be drained through a post.

[0021] In particular, another objective of the present invention is to provide a sky pergola with enhanced drainage function, which allows for height adjustment so that the folded fabric does not come into contact with the drain when folded by adding a spacer between the profile and the drain tray, thereby protecting the fabric while further enhancing the drainage effect. means of solving the problem

[0033] Hereinafter, preferred embodiments of the present invention will be described in more detail with reference to the attached drawings. Prior to this, terms and words used in this specification and claims should not be interpreted as being limited to their ordinary or dictionary meanings, and should be interpreted in a meaning and concept consistent with the technical spirit of the present invention in accordance with the principle that the inventor can appropriately define the concept of the terms to best describe his invention.

[0034] Therefore, the embodiments described in this specification and the configurations illustrated in the drawings are merely the most preferred embodiments of the present invention and do not represent all of the technical ideas of the present invention; thus, it should be understood that various equivalents and modifications that can replace them may exist at the time of filing this application.

[0036] [Enhanced drainage function Sky of the pergola composition]

[0037] The sky pergola with enhanced drainage function according to the present invention includes, as shown in [Figures 1] to [9] below, four posts (100), two first profiles (200), two second profiles (300), several bars (400), fabric (500), and actuators (600).

[0038] In particular, a water catcher (700) is added to the lower part of each of the first and second profiles (200, 300) so that rainwater falling on the fabric (500) and collecting at the edges can be drained through the post (100) without touching the fabric (500) when it is folded, thereby preventing rainwater falling on the fabric (500) from suddenly dripping and enhancing the drainage effect while creating a pleasant surrounding environment.

[0039] In addition, when mounting a water catcher (700) on the lower part of each of the first and second profiles (200, 300), a spacer (710) is added between them to adjust the mounting height, thereby preventing the fabric (500) folded between two adjacent bars (400) from touching the water catcher (700) or the rainwater collected inside the water catcher (700), thereby further enhancing the drainage effect.

[0041] The following is a more detailed explanation of this configuration with reference to the attached drawings.

[0042] A. Post

[0043] Four posts (100) are mounted at the location where the sky pergola according to the present invention is to be installed, as shown in [Figure 1] and [Figure 2]. At this time, four posts (100) are set up side by side to form a rectangular shape.

[0045] In particular, the above post (100) is made in a hollow form as shown in [Figure 3] and [Figure 8], so that rainwater collected in the water catcher (700) installed at the bottom of the first and second profiles (200) to be described later can be guided to fall through the hollow post (100).

[0047] B. First Profile

[0048] The first profile (200) has both ends mounted on the upper part of the post (100) described above, as shown in [Figures 1] to [5], and two first profiles (200) are mounted facing each other to guide the fabric (500) described later to be folded or unfolded.

[0050] In the first profile (200) above, as shown in [Figures 3] to [5], a roller (210), at least one chamber (220), a guide (230), at least one fastening hole (240), and an assembly groove (250) are formed along the entire length.

[0051] 1. Roller and guide

[0052] The guide (230) is mounted on the lower part of the first profile (200) as shown in [Figure 4] and [Figure 5]. This is configured so that the roller (210) is mounted on the guide (230) and slides, and a bar (400), which will be described later, is suspended from the lower part of the roller (210) to provide sliding guidance.

[0054] Accordingly, the guide (230) is configured such that the width cross-section of the lower part of the first profile (200) is formed in a "T" shape as shown in [Figure 5], and the roller (210) is mounted on the horizontal part to enable rolling motion, and at the same time, a part of the roller (210) protrudes below the first profile (200) through the vertical part so that a bar (400) to be described later can be mounted on the protruding part.

[0056] 2. Chamber

[0057] The chamber (220) is a type of space formed inside the first profile (200) when it is extruded, as shown in [Figure 5], and it reduces the weight of the first profile (200) while reinforcing its structural rigidity. It is preferable to form this chamber (220) as a single unit when manufacturing the profile by extrusion.

[0059] 3. Fastening hole

[0060] The fastening holes (240) are formed in several places on the cross-section of the first profile (200), as shown in [Figure 5]. Here, the fastening holes (240) are made using conventional techniques to allow screws used in assembly to be fastened when assembling the profile with another profile or with a panel, or to allow a connecting member to be inserted when connecting two members. In the drawing, the fastening holes (240) are shown as having a cross-section cut in the shape of a "C", and the formation location and number are selected to ensure stable support and fixation when assembled in this manner.

[0062] 4. Assembly Home

[0063] The assembly groove (250) is formed on the outer edge of the lower portion of the first profile (200) where the roller (210) is mounted, as shown in [Drawing 5]. At this time, the assembly groove (250) is intended to mount a water catcher (700) to be described later, but a spacer (710) may be additionally formed in between to extend the height.

[0065] As shown in [Figure 5], the assembly groove (250) is formed in an arc shape and is integrally configured with a protruding jaw at one edge. When assembling the part inserted into the assembly groove (250), the arc shape is inserted into the assembly groove (250) in an inclined state with the first profile (200), and then the assembly part is rotated to form a single plane. As a result, the arc shape rotates and the jaw catches, allowing the assembly state to be maintained. This assembly can be applied using the same technique used when assembling panels that are not too thick into a single plane.

[0067] C. Second Profile

[0068] The second profile (300) is respectively connected to both ends of the first profile (200) described above, as shown in [Figures 1] to [Figure 3], [Figure 6], and [Figure 9], so that the first and second profiles (200, 300) form a single rectangle.

[0070] At this time, the second profile (300) is installed so that two of them face each other as shown in [Figures 1] to [Figure 3], and one of them is equipped with an actuator (600) to be described later so that the fabric (500) can be folded or unfolded, and the other one is configured to cover the last bar (400) to be described later, which maintains the shape of the fabric (500) when the fabric (500) is unfolded, thereby allowing rainwater and the like to be drained smoothly along a predetermined path and reinforcing the structural rigidity of the second profile (300).

[0072] The above-mentioned second profile (300) includes a reinforcing part (310), a fastening hole (320), and an assembly groove (330), as shown in [Figure 3] and [Figure 6].

[0073] 1. Reinforcement part

[0074] The reinforcing part (310) is formed at the lower part of the second profile (300) as shown in [Figure 6]. At this time, the reinforcing part (310) is formed integrally in a bent shape at the end of the second profile (300) so that the last bar (400), which will be described later, can be positioned below it, thereby not only reinforcing the structural rigidity of the second profile (300), but also allowing rainwater, etc., to fall on the reinforcing part (310), so that the fallen rainwater, etc., falls back down and naturally flows down through the edge of the fabric (500), which will be described later.

[0076] 2. Fastening holes and assembly grooves

[0077] The fastening hole (320) and the assembly groove (330) have the same configuration as the fastening hole (240) and the assembly groove (250) described in the first profile (200) above, differing only in their formation locations, so only their formation locations are briefly explained here. Here, the fastening hole (320) is formed integrally at each end portion as shown in [Figure 6], and the assembly groove (330) is formed at the outer edge of the lower portion of the second profile.

[0079] D. B (Bar)

[0080] The bar (400) is formed in an upwardly convex arc shape as shown in [Figures 3] to [Figure 5], and both ends are mounted on rollers (210) mounted on each of the first profiles (200).

[0082] At this time, as shown in [Figure 3], the above bars (400) are arranged in parallel at equal intervals within a rectangle made of the first and second profiles (200, 400), and a fabric (500) to be described later is mounted thereon so that rainwater falling on the fabric (500) is guided to both ends of the above bars (400).

[0084] The above-mentioned bars (400) may be manufactured and used with the same thickness, or they may be configured to use two thick bars (400) installed at both ends to provide a frame function and prevent deformation. Of course, the two bars (400) installed at both ends may be manufactured in the form of long members rather than arc shapes.

[0086] E. Fabric

[0087] The fabric (500) is manufactured with an area size surrounded by the first and second profiles (200, 300) described above, as shown in [Figure 1], [Figure 3], and [Figure 4]. At this time, it is preferable to configure the fabric (500) so that its edge is positioned below each of the first and second profiles (200, 300), so that when the water catcher (700) described later is installed below the first and second profiles (200, 300), rainwater flowing down through the edge of the fabric (500) can be collected through the water catcher (700) and discharged to the outside.

[0089] Meanwhile, the above fabric (500) is preferably selected considering functions such as durability, water resistance, and UV protection, and examples of materials having these functions include canvas, acrylic fabric, polyester fabric, PVC coated fabric (vinyl-coated polyester, PVC fabric), HDPE (High-Density Polyethylene) mesh fabric, PTFE coated fabric (Teflon-coated fabric), and ETFE film (Ethylene Tetrafluoroethylene).

[0091] B. Actuator

[0092] An actuator (600) is mounted on one of the two second profiles (300), as shown in [Figure 2] and [Figure 3]. At this time, it is preferable to configure the actuator (600) so that it is installed in the middle of the second profile (600), thereby enabling the rollers (210) mounted on each of the first profiles (100) described above to be operated simultaneously and stably through a single actuator (600).

[0094] At this time, the actuator (600) forcibly pulls the roller (210) furthest from the two first profiles (100) installed facing each other on both sides to cause the fabric (500) mounted thereon to be folded like a wrinkle, or conversely, forcibly pushes the roller (210) to cause the folded fabric (500) to unfold. The configuration for driving the actuator (600) and the roller (210) can be applied as is to the technology of pergolas used as electric vehicles in the technical field to which the present invention belongs.

[0096] d. Gutter

[0097] The water collector (700) has a width cross-section as shown in [Figures 4] to [9], " It is formed in the shape of a bar and is installed by connecting one side to the outside at the lower part of the first and second profiles (200, 300) described above. At this time, the water catcher (700) is installed so as to be located below the end of the bar (400), so that even if rainwater falls on the fabric (500) and is guided to the edge of the fabric (500) and falls downward, it is collected in the water catcher (700) and can be easily drained along the water catcher (700) in a predetermined path.

[0099] In addition, it is preferable to configure the above-mentioned water catcher (700) so that both ends thereof can be connected into the post (100) as shown in [Figure 9], thereby allowing rainwater guided to the water catcher (700) to fall down through the post (100) and be drained stably.

[0101] As shown in [Figures 6] to [8], the above-mentioned water catcher (700) is integrally formed with at least one reinforcing projection (720), an assembly groove (730), a water barrier (740), and a fastening hole (750). Additionally, it is preferable to configure the water catcher (700) so that height adjustment is possible by installing a spacer (710) between the first and second profiles (200, 300) and the water catcher (700) so that when the fabric (500) is folded, the folded part does not come into contact with the water catcher (700).

[0102] 1. spacers

[0103] The spacer (710) is manufactured in the form of a strip with a predetermined width, as shown in [Figures 5] to [Figure 7]. At this time, the width of the spacer (170) is formed such that the folded fabric (500) does not touch the top of the water catcher (700).

[0105] In addition, as shown in [Figure 7], an arc-shaped assembly projection (711) is formed on each of the two edges of the spacer (710). At this time, the assembly projection (711) is fitted into the assembly groove (250) described above as shown in [Figure 5] and rotated so that it overlaps with each other and catches on the jaw so that it does not come off further. In this assembled state, both ends of the spacer (710) are fastened and fixed to the post (100).

[0107] In a preferred embodiment of the present invention, the spacer (710) is described as having assembly protrusions (711) formed on each of its edges, but is not limited thereto. That is, an assembly protrusion (711) may be formed on one edge of the spacer (710) and an assembly groove (250) configured in the first profile described above may be formed on the other edge, and the water tray (700) may be configured to be assembled with the assembly protrusion (711) described above instead of the assembly groove (730). That is, when assembling the first and second profiles (200, 300), the spacer (710) installed below them, and the water tray (700) in sequence, it is preferable to configure the assembly parts so that they can be selectively assembled using the assembly protrusion (711) and assembly groove (250) described above.

[0109] 2. Reinforcing protrusions

[0110] As shown in [Drawing 8], at least one reinforcing projection (720) is formed to protrude from the bottom portion of the water tray (700). At this time, the reinforcing projection (720) not only reinforces the rigidity of the water tray (700) but also serves the function of reinforcing it so that its shape is not easily deformed or damaged.

[0112] 3. Assembly grooves and fastening holes

[0113] The assembly groove (730) and the fastening hole (750) are configured similarly to the assembly groove (250) and the fastening hole (240) described above, as in [Figure 8], and only their formation locations differ, so only their formation locations are described here.

[0115] The assembly groove (730) is formed at the end of the longer of the two opposing sides in the water tray (700), as shown in [Figure 8]. Additionally, the fastening hole (240) is formed to protrude integrally next to each reinforcing projection (720) described above and on one side of the water level portion (740) described later.

[0117] 4. Order section

[0118] The water barrier (740) is formed to protrude inward from the edge where the assembly groove (730) is not formed, as shown in [Figure 8]. At this time, it is preferable to configure the water barrier (740) integrally so that it protrudes at an acute angle to the wall portion, so that even if water splashes and falls onto the water barrier (740) during the process of collecting water in the water collector (700), it does not splash outward.

[0120] The present invention, as described above, collects rainwater and other liquids falling on the fabric at both edges and guides the collected water and other liquids to fall stably through the posts under the guidance of the water collector, thereby improving the drainage effect.
