Description

Rainwater blocking curtain device linked to the opening and closing of a building door

[0001] The present invention relates to a rainwater-proof curtain mechanism linked to the opening and closing of a building door, and more particularly, to a rainwater-blocking curtain mechanism linked to the opening and closing of a building door, which protects a person from getting wet by folding an umbrella and entering a building through a door during rainy weather when an umbrella is needed, or by opening an umbrella and exiting a building without getting wet by opening an umbrella.

[0002] Buildings and structures typically have doors to allow the free entry and exit of goods and materials, as well as the passage of people. In particular, doors that can be opened and closed are essential for large entrances and exits, such as those used for transporting parts and materials in residential and commercial buildings, garages, factories, and warehouses.

[0003] These door configurations can be provided in various structures, such as a folding type, an upward folding structure, or an overhead type, depending on the method of operation.

[0004] Meanwhile, awnings or parasols are installed on first-floor entrances and balconies of buildings to block sunlight or protect against rain. Some awnings are attached to the building and automatically or manually unfold. Others are called awnings, which are typically rolled up and enclosed within a box and then unfolded across the front of the building.

[0005] Korean Patent No. 10-2107007 (hereinafter referred to as “Patent Document 1”) discloses a door-linked canopy opening / closing device.

[0006] The door-linked canopy opening / closing device of the above patent document 1 comprises: an opening / closing door that moves up and down with respect to a vertical profile; an up / down driving unit connected to a side of the opening / closing door to drive the opening / closing door up and down; a canopy portion provided on an upper portion of the opening / closing door; a power transmission unit disposed between the up / down driving unit and the canopy portion to transmit the power of the up / down driving unit to the canopy portion; and a linkage switch portion disposed adjacent to the power transmission unit to selectively connect and disconnect the power to the canopy portion so that the canopy portion is linked or disengaged with the operation of the opening / closing door. It is known that the canopy portion disposed adjacent to the opening / closing door can effectively block rainwater and sunlight compared to the related art, and when necessary, the canopy structure can be selectively linked to the opening / closing operation of the opening / closing door through the power transmission unit and the linkage switch portion having a relatively simple structure, thereby providing convenience to the user.

[0007] However, according to the prior art device according to the above patent document 1, the canopy is operated by a power mechanism, and when it rains, the canopy is opened in advance by operating a switch, so the mechanical configuration is very complex and heavy, so the overall size of the mechanism has to be increased to maintain structural rigidity, which causes a problem in that the installation cost increases.

[0009] [Patent Document]

[0010] (Patent Document 1) 1. Korean Patent No. 10-2107007 (registered on April 27, 2020)

[0011] The present invention has been proposed to solve the above problems, and the purpose of the invention is to provide a rainwater barrier mechanism linked to the opening and closing of a building door, which automatically opens or closes in conjunction with the opening and closing door of the building to block rainwater and allows one to enter and exit a building while folding or opening an umbrella to avoid rain during rainy weather, and which has a very simple structure and low installation cost because it does not require separate power supply.

[0012] In order to achieve the above object, the present invention provides a rainwater blocking curtain mechanism linked to the opening and closing of a building door, comprising: a rainwater blocking curtain member formed to block an open upper triangular opening of a door that opens and closes a building entrance by rotating around a hinge connection on one side; a door case-side mounting member formed on one side of the rainwater blocking curtain member and mounted on an upper frame side of a door case; and a door-side mounting member formed on the other side of the rainwater blocking curtain member so as to be mounted on the upper end of the door, characterized in that the rainwater blocking curtain member is spread out in a fan shape in conjunction with the opening of the door.

[0013] According to the present invention, a double-sided adhesive tape layer having an adhesive layer or an adhesive layer protected by a detachable backing paper is formed as a mounting means on the door case-side mounting member and the door-side mounting member, or a plurality of fitting holes are provided for fitting into hook members protrudingly formed on the upper frame of the door case and the upper part of the door, respectively.

[0014] According to a preferred embodiment of the present invention, the rainwater blocking curtain member is characterized by being a foldable member in the shape of a pleat that folds when the door is closed and unfolds into a fan shape when the door is opened.

[0015] According to the present invention, it is characterized in that an umbrella rib member made of metal or plastic material for reinforcing strength along a foldable fold that unfolds in a fan shape of the rainwater blocking visor fabric member is provided in a zigzag pattern to facilitate folding inside and outside of the rainwater blocking visor member.

[0016] According to the present invention, the rainwater blocking curtain fabric member is characterized in that one or more holes for ventilation are formed.

[0017] According to the present invention, the rainwater blocking curtain member and mounting member are characterized in that they are formed of a waterproof material member or a silicone member.

[0018] According to the present invention, a buffer member is connected to the door case-side mounting member, and the buffer member is composed of a first wing member, a second wing member, and a folding member connecting the first wing member and the second wing member, and when the second wing member is used by bonding or sewing to the door case-side mounting member of the blind mechanism, the first wing member is mounted on the upper frame of the door case.

[0019] According to the present invention, a rainwater blocking curtain mechanism linked to the opening and closing of a building door can be easily installed and used on a door and a door case through a mounting member, and is configured to automatically unfold or fold in a fan shape in conjunction with the opening and closing of the door, so that separate power devices are not required, and thus the installation cost is very low due to an extremely simple structure, and thus the opening at the top of the door can be blocked from rainwater in conjunction with the opening and closing of the door, so that an umbrella can be folded and unfolded without getting wet in the rain when it rains, and in particular, when opening the door and entering a building, it is possible to avoid rain while shaking off rainwater from the umbrella, thereby preventing contamination by rainwater inside the building.

[0020] Additionally, unlike existing canopy devices that are always in a protruding state, the canopy device is folded and stored when the door is closed, so there is no permanent protrusion that impairs the aesthetics.

[0021] In particular, when a buffer folding member is used in conjunction with a blind mechanism, the door's fast closing speed is buffered, preventing the door from colliding with an entrant, and at the same time, the buffer folding member has the effect of blocking the blind mechanism from being pushed between the closing door and the gap between the door.

[0034] The rainwater blocking curtain mechanism (hereinafter simply referred to as the “curtain mechanism”) for the opening and closing of a building door of the present invention is represented as a whole by reference numeral 10, and the curtain mechanism (10) according to the present invention is installed across the upper frame (12a) of the door (12) of the building and the upper frame (14a) of the quadrangular frame member, which is the door case (14) for installing the door (12) (see FIG. 1).

[0035] FIG. 3 is a drawing of the blind mechanism (10) of the present invention in an unfolded state, wherein the blind mechanism (10) includes a rainwater blocking blind member (20) that blocks an upper triangular opening (18) formed when a door (12) is opened, which is installed to open and close a building entrance by rotating around a hinge connection (16) on one side, which is a rotational starting point, when the door (12) is opened and closed, and the rainwater blocking blind member (20) has a fan shape when unfolded.

[0036] The fan-shaped rainwater blocking shield member (20) has a door case-side mounting member (22) extended with a predetermined width to be attached to the upper frame (14a) of the door case (14), which is a square frame chain woven from metal or wood, by adhesive on one side thereof, and a door-side mounting member (24) extended with a predetermined width to be attached to the upper frame (12a) of the door (12) by adhesive on the other side of the fan-shaped member. And the fan-shaped rainwater blocking curtain member (20) is manufactured using a woven fabric member that is easy to fold and unfold, preferably a waterproof fabric member that is waterproof, or a silicone member that is waterproof and easy to fold and unfold, and the door case-side mounting member (22) and the door-side mounting member (24) are formed integrally using the same material as the rainwater blocking curtain member (20), or are manufactured using different materials and formed by sewing or bonding them together.

[0037] FIG. 5 is a schematic drawing showing the appearance of the rain cover mechanism of the present invention as seen in the direction of arrow (C) with reference to FIG. 3, wherein the rain cover member (20) comprises a plurality of unit fan-shaped members (26a to 26g: 26 is used as a representative symbol) divided at a predetermined angle, and umbrella ribs (30a to 30g) are mounted along folded portions (28a to 28g) that extend radially from the vertex of the plurality of unit fan-shaped members (26a to 26g), and these umbrella ribs (30a to 30g) can be mounted to the rain cover member (20) in a manner similar to the way umbrella ribs are mounted on an umbrella or a folding fan (folding fan), or can be bonded using an adhesive.

[0038] FIG. 4 is a drawing showing a state in which the umbrella ribs of the rainwater blocking curtain mechanism for building door opening / closing according to the present invention are formed as thin plates with a predetermined width and the ends of the umbrella ribs overlap each other and are connected with a hinge axis (H), thereby showing a state in which the curtain mechanism (10) is unfolded in a fan shape with the hinge axis (H) as a starting point in conjunction with the opening of the door. At this time, the umbrella ribs (30: 30a to 30g) may be formed to be attached to only one side of the rainwater blocking curtain member (20) as shown in FIG. 4. However, as shown in FIG. 5, when folded by attaching them in a zigzag shape to the surfaces on both sides of the rainwater blocking curtain member (20), that is, when folded, the umbrella ribs (30a to 30g) mounted inside and outside of the fabric member in a zigzag shape are folded in a fan shape with the folding being facilitated more easily. That is, the zigzag arrangement of the umbrella ribs (30) is such that the fabric forming the shield member (20) is folded in a zigzag manner by wrapping each umbrella rib (30a to 30g) inside in a U shape (refer to the folding method of a folding fan), and when the door is opened, the shield member (20) unfolds like a folding fan unfolds.

[0039] The above umbrella ribs (30a to 30g) also have a function of preventing the surface area of ​​the rainwater blocking visor (20) from fluttering violently due to the wind pressure it receives when it is unfolded, and also, as an auxiliary device for selectively preventing fluttering, a weight (32) can be installed on each umbrella rib (30a to 30g) or on a selected umbrella rib, thereby preventing the occurrence of severe up-and-down fluttering due to the wind. To this end, the umbrella ribs (30) are formed of stainless steel, a metal material having high elasticity, or an elastic plastic material, and the weight (32) is formed of a metal material.

[0040] FIG. 6 is a drawing showing the cross-sectional layer structure of the door case-side mounting member (22) and the door-side mounting member (24). When the mounting members (22, 24) on both sides are formed as adhesive plate members as a mounting means, an adhesive layer (34) can be formed by applying an adhesive to one surface so that the upper frame (14a) of the door case (14) and the upper frame (12a) of the door (12) can be respectively attached to the square frame chain. More preferably, the adhesive layer (34) is not directly applied to the surfaces of the mounting members (22, 24) on both sides, but is formed by attaching a double-sided adhesive tape (38) having a detachable backing (36) that covers and protects the surface of the adhesive layer (34) to the surfaces of the mounting members (22, 24). When installing the mounting member on the door, the backing (36) can be simply removed and attached, so that the convenience of installation is very good. Since no special technology is required for installation, there is an advantage that the installation cost is almost zero.

[0041] The above double-sided adhesive tape (38) has adhesive layers (38, 42) applied to both sides of the film member (40), and double-sided adhesive tapes (36, 36) are detachably attached to the adhesive layers (38, 42) on both sides, so that the double-sided adhesive tape (38) is attached to the surface of the door case-side mounting member (22) and the door-side mounting member (24) by removing the double-sided adhesive layer (36) on one side, and in this state, the shield mechanism (10) is attached to the door (12) and the door case (14) so ​​that the adhesive layer (38) that remains attached is removed to protect the adhesive layer during installation, and the adhesive layer (38) exposed to the outside is pressed against the frame surface of the door (12) and the door case (14), thereby completing the installation.

[0042] FIG. 7 is a drawing showing a buffer member additionally used in a rainwater blocking curtain mechanism linked to a building door opening / closing according to the present invention, and the buffer member (45) is composed of a first wing member (47), a second wing member (48), and a folding member (50) connecting the first wing member (47) and the second wing member (48).
