Article 30, paragraph 2 of the Patent Act applies. Test date: April 7, 2023. Test location: JR East Oimachi Station (Oi 1-chome, Shinagawa-ku, Tokyo). Tester: JR East Building Tech Co., Ltd.. Disclosed details: A representative from JR East Building Tech Co., Ltd. installed the folding door for a folded-plate roof invented by Okudaira Rui, Yamaguchi Naoki, and Nakano Junko, and conducted a performance evaluation test.

The present invention relates to roofs installed on station buildings and the like, and in particular to panel doors attached to half-height roofs and the like.

At train stations and other facilities, roofs such as half-height roofs are installed above the platforms, and gutters such as eaves gutters and valley gutters are installed to drain rainwater that falls on the roof. Leaves, dust, sand, etc. accumulate in the eaves gutters that run horizontally along the roof, and as rainwater flows, leaves, sand, and mud accumulate in the drainage outlets (water collection areas) that connect to the downspouts, causing the gutters to become clogged. When the gutters become clogged, the rainwater that has accumulated in the gutters overflows and drips onto the platform.

A tool for preventing clogging near the drain outlet of such rain gutters is known (see Patent Document 1). In this tool, a pair of meshes with a hinge between them is installed over the drain outlet. When a worker pulls the wire from the platform, the flat mesh changes into a dogleg shape. By repeating this process, sediments such as sand and mud that have been on the mesh are removed, preventing the drain from clogging.

Japanese Patent Application Laid-Open No. 2023-8209

For example, leaves, sand, and mud tend to accumulate in areas other than the drain outlets in the valley gutters of a half-height roof. As the deposits solidify over time, there is a risk that rainwater will drip from areas other than the drain outlets. Meanwhile, due to the structure of the roof, removing deposits that have clogged valley gutters requires work on the roof. In the case of train stations and other structures, rooftop work is restricted due to train operations, making it difficult to deal with leaks immediately after they occur.

Therefore, there is a need for a roof structure that allows for easy removal of deposits and other debris that have accumulated in gutters without requiring work on the roof.

This invention focuses on the technical design of a sliding door that is installed to fill gaps in a corrugated half-roof.

The panel door of the present invention is configured as a panel door that closes the gap in the mountain-shaped portion of a folded-plate roof. It is possible to provide a folded-plate roof with a panel door installed to close the gap in the mountain-shaped portion of the folded-plate end located near the installed rain gutter (e.g., valley gutter). Here, the "mountain-shaped portion" refers to the portion of a folded-plate roof with a corrugated cross section that protrudes upward.

One aspect of the panel door of this invention comprises a frame that connects to a folding plate or tight frame, and a blocking section that closes the opening of the frame, with the blocking section being detachably fixed to the frame. Here, "detachably fixed to the frame" means fixing to the frame with the assumption that it can be removed and reattached as needed, and includes, for example, fixing to the frame in a way that allows removal and installation to be completed with a single removal or installation operation. On the other hand, fixing methods that are not intended to be removed once installed until replacement, such as fixing with screws, are not included.

Various fixing configurations are possible. A fixing member can be attached to the closure near the top edge of the opening, removably fixing the closure to the frame. For example, the fixing member can be configured using a corner fastener.

It is also possible to provide a holding member that can support the blocking section when it is removed. For example, a chain can be provided to connect the frame and the blocking section, and the blocking section can be supported by a member such as the chain when it is removed.

On the other hand, in another aspect of the present invention, the closing section is configured to be able to open and close around an axis near the inner edge of the frame. For example, the closing section can be attached and fixed to the frame by providing a hinge that rotates the closing section around an axis on the bottom side of the frame, and a fastener that holds the closing section in place by engaging with the top of the frame.

The blocking section can be configured as a light-transmitting window, allowing for visual confirmation of the clogging and accumulation of sediment. For example, it can be made of a transparent or translucent material.

The present invention provides a roof structure that allows deposits and other debris accumulated in gutters to be easily removed without requiring work on the roof.

FIG. 10 is a front view schematically showing a second embodiment of the door.

The following describes this embodiment of the folded-plate roof and the panel door used with the folded-plate roof, with reference to the drawings.

Figure 1 is a perspective view showing a schematic of a portion of a first embodiment of a folded-plate roof.

The corrugated plate roof 100 is configured as a roof installed on the platform of a station building (passenger shed) not shown. On the platform, columns with Y-shaped arms not shown are lined up at regular intervals in the center of the platform. The corrugated plate roof 100 is supported by Y-shaped arms and forms a Y-shaped roof that slopes (downward) from both ends of the platform's width direction toward the center of the platform.

The folded plate roof 100 is made up of a pair of folded plates, with one end facing each other in the center of the platform. Figure 1 shows one of the folded plates 110 that make up the folded plate roof 100. Note that while only the two peaks of the folded plate 110, sandwiching the valley portion between them, are shown, the corrugated shape of the folded plate 110 continues across the entire platform.

The folded plate 110 is fixed to a tight frame at one end 110T on the platform center side. However, the tight frame is not shown in Figure 1. As is well known, the tight frame is a frame with a corrugated shape that matches the corrugated shape of the folded plate 110, and is supported by a base material (beam) 120 installed along the center of the platform.

A valley gutter 200 is laid along the center of the platform of the corrugated roof 100. The valley gutter 200 is fixed to beams on both sides. Figure 1 shows the valley gutter 200 fixed to one beam 120 with screws (not shown). The valley gutter 200 is connected to a lower gutter 200, and a drain outlet 210 is formed at the connection.

A panel door 10 is provided at one end 110T of the folding plate 110 to close the gap in the mountain-shaped portion 110M of the folding plate 110. The panel door 10 is detachable and can be removed and reattached in a single operation. The configuration of the panel door 10 is described in detail below.

Figure 2 is a front view of the face door 10. Figure 3 is a side view of the face door 10. Unlike Figure 1, Figure 2 shows a view from the opposite side of the valley gutter 200.

The panel door 10 comprises a frame 20 and a window section 30. The frame 20 has a mountain-shaped configuration that matches the mountain section of the corrugated tight frame 300, and also forms a mountain-shaped opening 20P. For example, the frame 20 can be made of metal such as stainless steel.

As shown in Figures 2 and 3, the frame 20 forms a flange portion 22 along the edge of the opening 20P. The flange portion 22 forms an extension portion 22A that extends perpendicular to the frame main body 21, and the end of the extension portion 22A is folded to form a folded edge portion 22B that extends along the frame main body 21 (see Figure 2).

The window 30 closes the opening 20P in the frame 20 and allows light to pass through. This allows the original function of the panel door 10 to be fulfilled and also makes it possible to visually check the outside of the panel door 10, particularly the condition of the valley gutter 200. In this case, the window 30 has a mountain-shaped configuration, similar to the opening 20P in the frame 20P, and is fixed to the edge portion 22B of the flange portion 22 with screws. For example, the window 30 can be made from a material such as a PET plate.

A fixing member 50 is attached to the window 30. Specifically, a fixing bracket 60 with a U-shaped cross section is attached to the window 30 by screwing, and the fixing member 50 is fixed to the outer surface 60S of the fixing bracket 60 by screwing. In this case, the fixing member 50 is configured as a corner fastener.

The fixing member 50 is attached so that it contacts the outer surface 60S of the fixing bracket 60S, which are perpendicular to each other, and the surface of the extension 22A of the flange portion 22. The fixing member 50 secures the window 30 to the frame 20 by tightening the two surfaces together using the force of an elastic member (spring) (not shown). The locking portion 53 restricts and stops the movement of the lever 52, which rotates on its axis. When a worker rotates the lever 52 on its axis (see →A in Figure 2), the lever 52 is released from its locked state, and the window 30 falls under its own weight. The structure of corner fasteners is well known, so a detailed explanation will be omitted.

On the other hand, the panel door 10 is provided with a chain 70 that connects the frame body 21 and the window 30. The chain 70 can support the window 30 when the panel door 10 is removed from the frame 20.

When workers are removing leaves, sand, mud, etc. that have accumulated in the valley gutter 200 (especially near the drain outlet 210), they remove the face door 10 installed next to the valley gutter 200 and reach out to perform the cleaning work. After completing the cleaning work, the face door 10 is reinstalled in the same place.

As explained above, the panel door 10 of this embodiment is installed on the mountain-shaped portion 110M of the end 110T of the folded plate 110 located near the valley gutter 200 of the folded plate roof 100. The panel door 100 comprises a frame 20 and a window 30, with a fixing member 50 attached to the window 30 and a chain 70 connecting the frame 20 and the window 30.

The detachable fastening allows the window 30 to be removed from the frame 20 simply by operating the fixing member 50 once (rotating the lever shaft) due to the weight of the fixing bracket 60 and fixing member 50. The removed window 30 is supported by the chain 70.

The fixing member 50 is constructed with a corner fastener, which provides a double locking function that also includes the locking of the lever 52, securing the window 30 to the frame 20. This allows the window 30 to be easily removed and installed with a simple operation, while also providing secure fixation and preventing accidental opening and closing. In particular, since the fixing member 50 is secured near the top edge of the opening 20P of the frame 20, removal and installation are easy.

Furthermore, because the fixing member 50 is attached to the window 30 via the fixing bracket 60, it is easy to switch from an existing window door to this embodiment of the window door without replacing or modifying the frame 20.

Because the window 30 is detachable from the frame 20, the size of the window 30 can be maximized, making it easier for workers to pass their arms through the window 30. As a result, the efficiency of cleaning the valley gutter 200 is improved.

Next, we will explain the second embodiment of the sliding door using Figure 4. In the second embodiment, the window 30 opens and closes by rotating around an axis relative to the frame 20.

Figure 4 is a front view showing a schematic representation of a second embodiment of the panel door. The frame 20 and window 30 that make up the panel door 10' are connected by a hinge 75'. The hinge 75' is located on the bottom side of the frame 20. The window 30 can rotate around the hinge 75', opening and closing the opening 20P in the frame 20.

A fastener 50' is attached to the top side of the window 30. In this case, it consists of a so-called catch clip.

The fastener 50' contacts the extension 22A of the flange 22 of the frame 20, and secures the window 30 to the flange 22 of the frame by the elastic force of the spring. When the worker rotates the lever 52' of the fastener 50' around its axis, the locked state is released and the window 30 can be removed from the frame 20. Note that this type of fastener 50' is well-known technology, so a detailed description will be omitted.

This configuration of the second embodiment also makes cleaning easy. Because the fastener 50' is attached directly to the window 30, the front side does not get in the way even when the window 30 is open. Furthermore, because the hinge 75' is located near the bottom edge of the opening 20P in the frame 20, the window 30 can be easily opened and closed.

Regarding the installation location of the roof door, it can also be applied to roof doors located near rain gutters other than the valley gutter 200. The roof door can also be fixed directly to the corrugated plate, and can be attached to a location other than the end. The corrugated plate roof 100 can also be applied to buildings other than station buildings.
