[0045] Preferred embodiments of the present invention will be described in detail below with reference to the attached drawings.
[0046] 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, but should be interpreted in a meaning and concept consistent with the technical spirit of the invention, based on the principle that the inventor can appropriately define the concept of the terms to best describe his invention. Accordingly, the embodiments described in this specification and the configurations illustrated in the drawings are merely one preferred embodiment of the invention and do not represent all of the technical spirit of the invention; therefore, it should be understood that various equivalents and modifications capable of replacing them may exist at the time of filing this application.
[0047] Based on Figure 1, the direction is specified as the upper or upper side for the housing side and the lower or lower side for the outer cap side.
[0048] As illustrated in FIGS. 1 to 11, the ceiling water-collecting sheet structure of an underground parking lot according to the present invention is,
[0049] It is largely composed of a sheet (10), a hanger unit (20), and a water collection unit (30).
[0050] If we look at each component,
[0051] The above sheet (10)
[0052] As illustrated in FIGS. 1, 2, 9, 10, and 11,
[0053] It is made of a square sheet structure having an upper and lower through-hole (11) in the central area.
[0054] At this time, the sheet (10) is preferably made of a material such as poly ripstop or poly oxford, which has a waterproof function with a water pressure resistance of approximately 1500 to 2000 mm.
[0055] And as shown in FIG. 9, it is preferable that the sheet (10) be formed into a rectangular structure corresponding to or larger than the parking surface where the vehicle is parked.
[0056] The above hanger unit (20) is
[0057] As shown in FIGS. 9 and 10,
[0058] The above sheet (10) is intended to be hung from the ceiling of an underground parking lot with the central area sagging while spread horizontally.
[0059] A plurality of eyelets (21) provided at regular intervals along the perimeter of the sheet (10), and
[0060] A plurality of wires (22) connected to each of the above eyelets (21)
[0061] It consists of including
[0062] At this time, a separate clamp or the like may be provided at the end of each wire (22) so that it can be easily connected to a ceiling structure such as a drain pipe or a drain pipe fixing member using this clamp.
[0063] The above water collection unit (30) is
[0064] As illustrated in FIGS. 1 to 8,
[0065] It is placed in the central hole (11) of the above sheet (10) and is intended to allow water falling from the ceiling of the underground parking lot to flow along the above sheet (10) and be collected.
[0066] A housing (31) having a lower outlet (311) positioned on the lower side of the central hole (11) of the above sheet (10),
[0067] A holder (32) formed to extend along the upper circumference of the housing (31) and mounted in the upper peripheral area of the central hole (11) of the sheet (10), and
[0068] An inner cap (33) responsible for opening and closing the outlet (311) of the above housing (31)
[0069] It consists of including
[0070] At this time, as shown in FIG. 2, the outlet (311) of the housing (31) is preferably circular in cross-sectional space, and the housing (31) is made of a hemispherical structure made of a light-transmitting material, so that the water level of the water collected in the housing (31) can be easily checked visually from the outside.
[0071] And the holder (32) is fixedly attached by an adhesive or the like so as to be in close contact with the upper peripheral area of the central hole (11) of the sheet (10).
[0072] And the inner cap (33) is composed of a head (331) having a circular cross-section that is fitted into the outlet (311) of the housing (31), a flange (332) formed integrally on the lower part of the head (331) and contacting the lower circumference of the outlet (311) of the housing (31), and a grip (333) formed integrally on the lower part of the flange (332).
[0073] Here, it is preferable that the head (331) has a diameter such that it can be forcibly fitted into the outlet (311) of the housing (31), that is, a diameter slightly larger than that of the outlet (311). Additionally, it is preferable that the head (331) be made of an elastic material, so that it can be fitted while elastically deforming when forcibly fitted into the outlet (311), thereby increasing the sealing force on the outlet (311).
[0074] And the above flange (332) is seated along the lower circumference of the outlet (311) of the housing (31).
[0075] And the above grip (333) is intended for handling, such as holding it with the user's hand and pulling or pushing it in, and it is desirable to have a square cross-sectional structure to provide a good grip.
[0076] And as shown in FIGS. 4 and 5, the water collection unit (30) is further provided with an outer cap (34) that is connected to the outlet (311) of the housing (31) and accommodates the inner cap (33).
[0077] At this time, as shown in FIG. 6, the outer cap (34) is formed with a top pusher (341) that presses the flange (332) of the inner cap (33) when connected to the outlet (311), thereby further increasing the mutual contact force between the lower end of the outlet (311) of the housing (31) and the flange (332) of the inner cap (33), so that the gap between the lower end of the outlet (311) of the housing (31) and the flange (332) of the inner cap (33) can be eliminated, thereby preventing leakage as much as possible.
[0078] Furthermore, as shown in FIG. 6, when the outer cap (34) is connected to the outlet (311), the inner bottom of the outer cap (34) presses the grip (333) of the inner cap (33), thereby helping to increase the mutual contact force between the lower end of the outlet (311) of the housing (31) and the flange (332) of the inner cap (33), just like the top pusher (341), but the degree of pressure may be weak.
[0079] To resolve this, as shown in FIG. 7, an upwardly protruding bottom pusher (342) is further formed on the inner bottom of the outer cap (34), so that when the outer cap (34) is connected to the outlet (311), the bottom pusher (342) can further press the grip (333) of the inner cap (33).
[0080] And as shown in FIGS. 7 and 8, as the inner cap (33) has a pair of flat sections (334) facing each other along the upper circumference of the head (331), when the inner cap (33) is pulled downward from the outlet (311) of the housing (31), each flat section (334) comes out of the outlet (311), and drainage occurs into the space (S) between the outlet (311) of the housing (31) and each flat section (334).
[0081] Ultimately, a pair of flat sections (334) are formed facing each other on the upper outer surface of the head (331), and since each of these flat sections (334) is not in contact with the water outlet (311) of the housing (31), a space (S) is secured between them and the water outlet (311). When the grip (333) is grasped and pulled while the lower outer surface of the head (331) is blocking the water outlet (311), the lower outer surface of the head (311) moves away from the water outlet (311), and the space (S) is opened, allowing water to be drained into the space (S). Through this structure, the amount of water collected in the housing (31) can be adjusted according to the degree of opening of the space (S) when draining water.
[0082] Meanwhile, as shown in FIGS. 10 and 11, the sheet (10) further has a viewing window (12) made of a light-transmitting material extending from the central hole (11) to the area before reaching the outer end of the sheet (10), and two or more membranes (13) made of an elastic material that surround the central hole (11) at spaced intervals and are arranged at equal intervals, and are elastically deformed to be convex downward when water accumulates.
[0083] Here, the above-mentioned viewing window (12) helps to easily visually check the water level of the sheet (10) when the water collected in the housing (30) overflows and is collected up to the sheet (10), and each membrane (13) is made of a thin membrane structure having elasticity, so when water fills up to the location of each membrane (13), each membrane (13) is elastically deformed by the weight of the water and becomes convex downward. Ultimately, the water level can be easily determined through the degree of such deformation.
[0084] In describing the present invention above, the focus has been on a "ceiling water collection sheet structure for an underground parking lot" having a specific shape and structure with reference to the attached drawings; however, the present invention is capable of various modifications and changes by those skilled in the art, and such modifications and changes should be interpreted as falling within the scope of protection of the present invention.
