Description

  The present invention relates to a drainage unit, a drainage system, and a drainage method. More specifically, the present invention relates to a drainage unit, a drainage system, and a drainage method that can efficiently drain water accumulated in a door support receiving the lower end of the outer peripheral edge of the door through a drainage unit, although having a simple configuration.

  Conventionally, a slide-type door installed at the entrance of a building has a long groove-like rail as a door support that slidably supports the lower end of the outer peripheral edge of the slide-type door, In many cases, the rail is embedded such that the groove portion is lower than the ground.

  As an example of such a rail, a lower guide rail 91 as described in FIG. 3 of Patent Document 1 has been proposed, and the configuration of the lower guide rail 91 is shown in FIGS. 13 (a) and 13 (b). . As shown in FIG. 13B, the lower guide rail 91 is formed with a long groove-shaped guide groove 92, and this lower guide rail 91 is generally used for the sliding door 90. belongs to.

JP 2007-32145 A

  By the way, when the sliding door 90 slidably supported by the lower guide rail 91 through the guide groove 92 is installed at the entrance to the outside of the building, rainwater, snowmelt water, washing water, etc. "Rain water" is attached to the outer surface of the sliding door 90 and flows down as it is, or flows along the ground to the lower guide rail 91, so that it is lower than the ground F1. Rainwater or the like is likely to flow into and accumulate inside a guide groove 92, and there is no route for draining the accumulated water to the drainage channel, so drainage from the guide groove 92 must be performed manually. The workload is heavy.

  Further, when wind and rain continue and water exceeding the capacity of the guide groove 92 flows, the water overflows indoors from the gap between the guide groove 92 and the sliding door 90 on the indoor side. It is necessary to frequently wipe off the water in the guide groove 92 in order to wet the floor surface F2 or make a stain on the floor mat, etc., and the drainage work is frequently performed. There is a risk of being restrained by drainage work over a period of time.

  In addition, when draining from the guide groove 92, it is necessary to expose the guide groove 92 after the sliding door 90 is once opened. There is a risk of wetting the floor surface F2.

  The present invention was devised in view of the above points, and can easily drain water collected in the door support receiving the outer peripheral edge of the door through the drainage unit while having a simple configuration. It aims at providing a drainage unit, a drainage system, and a drainage method.

  In order to achieve the above object, the drainage unit of the present invention is detachably covered with a bottomed box-shaped main body portion that receives inflowing water and an upper opening of the main body portion. A lid portion in which a water passage portion is formed, and a long groove-like door support member that receives the outer peripheral edge of the door and supports the door, and the main body portion. And a drainage part that is connected to the main body part and communicates with the drainage channel.

  And since it has a bottomed box-shaped main body part that receives the inflowing water, in addition to the water that directly flows into the main body part from the upper opening, the water that accumulates in the side-by-side door support is also, for example, a water guiding part described later This main body can be made to function as a drainage collector for various types of drainage.

  Furthermore, since the lid portion is provided so as to be detachably covered at the upper opening of the main body portion and formed with a water passage portion that communicates the inside and outside of the main body portion, the lid can be covered without the pedestrian taking his feet under the upper opening. While being able to go to the door through the part, the lid part can be removed and the main part can be easily accessed for cleaning work. Moreover, the water overflowing from the inside of the door support smoothly flows into the main body through a water passage such as a hole or a slit without accumulating on the lid. There is no slip. Thereby, the pedestrian's passability and the workability of the cleaning work can be improved while sufficiently exhibiting the function of the main body as a water collector.

  In addition, it is provided between a long groove-shaped door support that receives the outer peripheral edge of the door and supports the door and the main body, and includes a water guide that communicates between the inside of the door support and the main body. Therefore, the water which accumulates in a door support can be made to flow in into the main part of a drainage unit via this water guide.

  And since it is provided in the main body part and the drainage part which connects the inside of a main body part to a drainage channel is provided, the water which flowed in and gathered in the main body part can be discharged | emitted to a drainage channel via this drainage part. With such a simple configuration in which the water guide portion, the main body portion, and the drainage portion are connected in series, the water accumulated in the door support can be efficiently discharged from the drainage portion to the drainage channel.

  With the configuration as described above, the drainage unit of the present invention can be operated manually even when rainwater or the like adheres to the outer surface of the sliding door and flows down as it is and accumulates in the door support. The drainage to the drainage unit can be automatically performed without performing the drainage work by the. This can reduce the work load of drainage work, and reliably prevent troubles such as water overflowing from the door support or opening the door once for drainage work to wet indoor floors. be able to.

  Moreover, even if earth and sand, pebbles, garbage, tree branches, etc. (hereinafter referred to as “impurities”) accumulate in the door support, such impurities are collected through the drainage unit together with the accumulated water. Since it is discharged to the drainage channel, the cleaning work that was previously performed for each of the door support and the drainage unit can be completed only by the drainage unit. Thereby, reduction of the work load by the cleaning work regarding a door support can also be aimed at.

  Moreover, a main-body part has a concave collar part in a bottom face, and the 1st connection port connected to a water conveyance part and the 2nd connection port connected to a drainage part are formed facing the side wall part of a collar part. In addition, when the first axis passing through the first connection port from the inside of the water guide portion and the second axis passing through the inside of the drainage portion from the second connection port are arranged in parallel to each other, Water that has flowed into the pipe can flow linearly toward the second connection port. Thereby, while the passage distance of the water in a collar part becomes short, the flow of water becomes a laminar flow, the drainage speed is stabilized, and drainage efficiency can be improved.

  Furthermore, the eaves part can be set at a position lower than the bottom surface of the main body part, and the water flowing into the main body part from the upper opening joins the water from the water guiding part due to the flow of water caused by this height difference. However, the flow rate is less likely to decrease, and drainage efficiency can be further improved.

  In addition, the buttock can function as a trap structure that sinks and stores impurities in the water, and most of the impurities that flow with the water in the main body sink to the bottom of the buttock. The cleaning workability can be further improved by cleaning around the center.

  In addition, when the lower edge of the first connection port is set higher than the lower edge of the second connection port, the water that has flowed into the collar from the first connection port flows down in the direction of the second connection port. Combined with the effect of the connection ports being formed opposite to each other on the axial centers arranged close to each other in parallel, water can flow more linearly.

  Furthermore, even if water accumulates too much in the buttock, drainage from the second connection port is prioritized so that the water surface is less likely to exceed the lower edge of the first linking port, and the water in the buttock flows back to the water conveyance unit. Can be prevented.

  Further, when the first connection port is formed inside the second connection port when viewed from the direction of the intermediate axis that is between the first axis and the second axis and is parallel to both axes, Most of the water that has flowed into the collar can be made to flow in the direction of the second connecting port without being dispersed in the periphery, and each connecting port is opposed to each axial center arranged close to each other in parallel. Combined with the effects of the formation, the water can flow more linearly.

  In addition, when at least a part of the lower edge of the second connection port is set at substantially the same height as the bottom surface of the flange, the water flow from the inside of the flange to the second connection port is further smoothed, and the drainage efficiency Can be further improved.

  In addition, when the flange has a movement suppression structure that forms a concave corner from the bottom surface of the flange to the side wall that opens the second connection port, and applies water to the corner to suppress the movement of impurities in the water, Even if coarse and heavy impurities are present at the bottom of the running water, the coarse and heavy impurities are bounced off by the corners, making it difficult to move further into the second connection port, and into the second connection port for coarse and heavy impurities. Can be prevented, and the clogging of the drainage portion connected to the second connection port can be reliably prevented.

  In addition, combined with the effect of the trap structure described above, most of the impurities that flow into the main body together with water can be deposited on the bottom of the buttock, and cleaning work is performed by cleaning around the buttock. The property can be further enhanced.

  Moreover, when it has the inclined surface which inclines below toward the 1st connection port side from the door support side at the flow-path bottom face of a water guide part, the water which flowed in in the water guide part is made to flow down along this inclined surface. Thus, the flow rate can be increased, the flow rate of water in the collar can be increased, and the drainage efficiency can be further improved.

  In addition, this inclined surface is, for example, an aspect formed in a right-angled triangle shape in a side view in which the upper surface side of the water guide portion is flat and the bottom surface side is inclined downward, and a portion formed in a right-angled triangle shape in a side view on the bottom surface side of the water guide portion A mode in which flat portions are combined to form a right-angled trapezoidal shape when viewed from the side, a mode in which a member that forms an inclined surface is inserted into a cylindrical water guide portion, and the like are included, and there is no particular limitation.

  Furthermore, during drainage, impurities accumulated in the door support may flow into the water guide along with water, but the formation of such an inclined surface causes impurities, especially round sand, to roll. As described above, the flow rate of water is also increased, so that sand or the like is efficiently discharged in the direction of the buttock without accumulating in the water conveyance section. It settles and settles at the bottom of the part.

  Thereby, the above-mentioned inclined surface not only improves drainage efficiency, but also eliminates the need to clean the inside of the water conduit and can further increase the efficiency of the cleaning operation in the drainage unit.

  In addition, when the water passing portion is a long slit that penetrates the inside and outside of the main body, and a plurality of slits are formed in parallel to the longitudinal direction of the door support, it overflows from the inside of the door support. Since not only water but also water flowing from the side opposite to the door support smoothly flows into the main body without flowing along the lid, it does not accumulate on the lid. Thereby, a pedestrian who goes to a door does not slip on a cover part, and can improve pedestrian's trafficability further.

  Here, when each slit is orthogonal to the longitudinal direction of the door support, the advancing direction of the pedestrian toward the door coincides with the direction in which the lid between the slits extends, and the contact area between the sole and the lid surface Increases, the frictional resistance decreases, and it becomes slippery. In particular, it is slippery when the lid surface is covered with a thick water film.

  On the other hand, when the slit is parallel to the longitudinal direction of the door support as in the present invention, the advancing direction of the pedestrian toward the door intersects the direction in which the lid between the slits extends, and the sole and the lid The contact area with the surface decreases, the frictional resistance increases, and it becomes difficult to slip. In particular, when such thin slits and the surface of the lid portion are alternately and continuously arranged on the sole, the locking action of the corner of the lid portion is also added, even if the lid surface is covered with a thick water film Since it becomes difficult to slip even in such a state, each slit can exhibit an excellent anti-slip effect on the pedestrian's foot toward the door.

  Further, the main body portion is provided with a long flange-shaped protruding edge portion protruding outward in the upper opening, and the protruding edge portion is limited to a portion substantially parallel to the longitudinal direction of the door support. If you have a draining structure that suppresses the flow of water in the short direction of the door support, the outer periphery of the upper opening parallel to the flow of water flowing from the opposite side of the door support Since the above-mentioned overhanging edge portion is not provided and only a thin edge portion including only a cross section in the plate thickness direction of the main body portion is exposed, water can flow along the upper surface of the edge portion. Without being drained, it flows down into the main body. Thereby, the quantity of the water which flows to the door through the upper surface of a drainage unit can be reduced, and the water itself which accumulates in a door support can be reduced.

  In order to achieve the above object, the drainage system of the present invention includes a long groove-like door support that receives the outer peripheral edge of the door and supports the door, and a bottomed box-shaped main body that receives inflowing water. A lid that is detachably covered at the upper opening of the main body and has a water passage portion that communicates the inside and outside of the main body, and is interposed between the door support and the main body, And a drainage unit having a drainage part that communicates with the interior of the main body part, and a drainage part that communicates with the drainage channel.

  And since it has a long groove-like door support that receives the outer periphery of the door and supports the door, the members necessary to open and close the door are placed on the door support outside the door and attached to the door itself The increase in the size and weight of the door can be suppressed, and the door installation and opening / closing operability can be improved.

  Furthermore, a bottomed box-shaped main body part that receives inflowing water, a cover part that is detachably covered at the upper opening of the main body part, and has a water passage part that communicates the inside and outside of the main body part, door support A drainage unit having a drainage part interposed between the fixture and the main body part and communicating with the interior of the door support and the main body part, and a drainage part connected to the main body part and communicating with the drainage channel in the main body part Even when rainwater, etc. adheres to the outer surface of the sliding door and flows down as it is and accumulates in the door support, the drainage unit does not have to be drained manually. Can be automatically drained. This can reduce the work load of drainage work, and reliably prevent troubles such as water overflowing from the door support or opening the door once for drainage work to wet indoor floors. be able to.

  Moreover, even if impurities accumulate in the door support, such impurities are discharged together with the accumulated water to the drainage channel through the drainage unit. The cleaning work that has been carried out for each of them can be done with only the drainage unit. Thereby, reduction of the work load by the cleaning work regarding a door support can also be aimed at.

  Specifically, since it has a bottomed box-shaped main body portion that receives inflowing water, in addition to water flowing directly into the main body portion from the upper opening, water accumulated in the side-by-side door support is also, for example, a water guide described later This main body can be made to function as a drainage collector for various waste waters.

  Since it has a lid part that is detachably covered in the upper opening of the main body part and has a water-permeable part that communicates the inside and outside of the main body part, the pedestrian can be placed on the lid part without taking his feet under the upper opening. In addition to being able to go through to the door, it is possible to remove the lid and easily access the main body to perform a cleaning operation. Moreover, the water overflowing from the inside of the door support smoothly flows into the main body through a water passage such as a hole or a slit without accumulating on the lid. There is no slip. Thereby, the pedestrian's passability and the workability of the cleaning work can be improved while sufficiently exhibiting the function of the main body as a water collector.

  Since it has a water guide that is interposed between the long groove-like door support that receives the outer periphery of the door and supports the door and the main body, and that communicates between both the door support and the main body, By passing through the water guide portion, water accumulated in the door support can be caused to flow into the main body portion of the drainage unit.

  Since it has the drainage part which is connected to the main body part and communicates with the drainage channel in the main body part, the water that has flowed into the main body part and collected can be discharged to the drainage channel through this drainage part. With such a simple configuration in which the water guide portion, the main body portion, and the drainage portion are connected in series, the water accumulated in the door support can be efficiently discharged from the drainage portion to the drainage channel.

  In order to achieve the above object, the drainage method of the present invention allows the water flowing into the long groove-like door support that receives the outer peripheral edge of the door to support the door, and has the presence of the door support and the drainage unit. A water guide step that leads to the main body through a water guide that is connected to the bottom box-shaped main body, and water from inside the door support can be attached to and detached from the top opening of the main body. A drainage step for discharging to the drainage channel through the drainage part connected to the main body part together with the water flowing into the main body part through the water passing part of the covered lid part.

  Then, the water flowing into the long groove-like door support that receives the outer peripheral edge of the door and supports the door is communicated between the door support and the bottomed box-shaped main body of the drainage unit. Since it has a water guide step that leads to the main body through the installed water guide, even when rainwater etc. adheres to the outer surface of the sliding door and flows down as it is, it accumulates in the door support. Rainwater or the like can be automatically moved to the main body without performing manual drainage work as in the prior art. This can reduce the work load of drainage work, and reliably prevent troubles such as water overflowing from the door support or opening the door once for drainage work to wet indoor floors. be able to.

  In addition, even if impurities accumulate in the door support, such impurities are moved to the main body together with the accumulated water, so it was previously performed for each of the door support and the drainage unit. Cleaning work can be done only with the drainage unit. Thereby, reduction of the work load by the cleaning work regarding a door support can also be aimed at.

  Furthermore, the water from the inside of the door support is connected to the main body together with the water flowing into the main body through the water passing portion of the lid that is detachably covered at the upper opening of the main body. Since it is equipped with a drainage step that drains to the drainage channel via the drainage unit, the main unit functions as a drainage collector for various drainage, and the water accumulated in the door support is supplied to the water guide unit, main unit, and drainage. It is possible to efficiently discharge from the drainage section to the drainage channel through a simple configuration in which the sections are simply provided.

  Moreover, since the lid as described above is covered, the pedestrian can go to the door through the lid without taking his feet in the upper opening, and can easily be removed into the main body by removing the lid. It can be accessed and cleaned. In addition, the water overflowing from the inside of the door support does not collect on the lid, but smoothly flows into the main body through a water passage such as a hole or slit. I wo n’t slip. Thereby, the pedestrian's passability and the workability of the cleaning work can be improved while sufficiently exhibiting the function of the main body as a water collector.

  Although the drainage unit, drainage system, and drainage method of the present invention have a simple configuration, the water collected on the door support receiving the lower end of the outer peripheral edge of the door can be efficiently drained through the drainage unit. It has become.

(Work)
The effects of the present invention will be described with reference to FIGS. 1 to 6 (particularly FIG. 4). As shown in FIG. 6A, the door support 1 receives and supports the lower edge of the outer periphery of the sliding door 3 as described above, and can guide movement in the opening / closing direction along the groove 10. ing.

  Since the sliding door 3 is installed at the entrance to the outside of the building, rainwater adheres to the outer surface and flows down as it rains, or rainwater that travels on the ground flows through the door support 1. Or flow in.

  However, according to the drainage system A of the present invention, the water accumulated in the door support 1 is discharged from the drain hole 12 to the water guide portion 23 and flows into the main body portion 20 through the water guide portion 23. Can do. In FIG. 4, this water flow W1 is indicated by an arrow line.

  Furthermore, rainwater that travels on the ground also flows into the main body 20 through the slit 221 of the covered cover section 22, and the main body 20 can function as a drainage collector for various drainage. The same applies to the drainage system A1 having a plurality of holes through which the water passage portion passes, as shown in FIG. In FIG. 4, the flow W2 and W3 of the water which flows into the main-body part 20 via the slit 221 are shown by the arrow line.

  In addition, since the main body 20 has a draining structure in the upper opening 20a as described above, the water flowing from the side opposite to the door support 1 is caused to flow down into the main body 20 as indicated by the flow W3, for example. The amount of water flowing to the door through the upper surface of the drainage unit 2 can be reduced, and the water itself that is accumulated in the door support 1 can be reduced.

  And in the collar part 21 formed in the bottom face 203 of the main-body part 20, while the 1st connection port 230 and the 2nd connection port 240 are formed facing the side wall part 211 as mentioned above, it is the 1st axis. 51 and the second axis 52 are arranged in parallel and close to each other, and the lower edge 230a of the first connection port 230 is set at a higher position than the lower edge 240a of the second connection port 240. As the first connecting port 230 is formed inside the second connecting port 240 in the direction of the intermediate shaft 53, the first connecting port 230 flows into the flange portion 21 from the first connecting port 230 as shown in the flow W <b> 1. Most of the water can flow linearly in the direction of the second connection port 240 without being dispersed around.

  Thereby, while the passage distance of the water in the collar part 21 becomes short, the flow of water becomes a laminar flow, drainage speed is stabilized, and drainage efficiency can be improved. Further, since the flange portion 21 is positioned lower than the bottom surface 203 of the main body portion 20, the flow of water flowing into the main body portion 20 from the upper opening 1a indicated by the flows W2 and W3 is accelerated by this height difference. Moreover, the flow velocity of the water flow W1 from the water guide portion 23 is unlikely to decrease, and the drainage efficiency can be further improved.

  In addition, since the lower edge 230a of the 1st connection port 230 is higher than the lower edge 240a of the 2nd connection port 240, even if water collects too much in the collar part 21, the waste_water | drain from the 2nd connection port 240 is drained. Priority is given to making it difficult for the water surface to exceed the lower edge 230a of the first connection port 230, and it is possible to prevent the water in the collar portion 21 from flowing back to the water guide portion 23 (see FIGS. 4 and 5). .

  Then, the bottom surface 210a of the flange portion 21 and at least a part of the lower edge 240a of the second connection port 240 are set to have substantially the same height, so that the effects and advantages of the arrangement of the first connection port 230 are combined. Thus, the flow of water from the flange 21 toward the second connection port 240 can be further smoothed, and the drainage efficiency can be further improved. And the water collected in the main-body part 20 can be discharged | emitted by the drainage part 24 connected to this 2nd connection port 240 to a drainage channel (refer FIG. 5).

  Furthermore, by forming the slit 221 as described above in the lid portion 22, not only the water (running water W <b> 2) overflowing from the inside of the door support 1, but also flows from the opposite side of the door support 1. Since water (running water W3) also flows smoothly into the main body part 20 without flowing along the lid part 22, it does not accumulate on the lid part 22, and in addition, Since the contact area is reduced and the frictional resistance is increased, an excellent anti-slip effect can be exerted on the pedestrian's feet toward the door, and the pedestrian's trafficability can be further enhanced.

  The lid portion 22 prevents large-sized impurities from entering the main body portion 20, and the lid portion 22 can be easily accessed inside the main body portion 20 by being removed so that the inside can be cleaned.

  In addition, the collar part 21 can function as a trap structure part that sinks and stores impurities in the water, and most of the impurities that flow into the main body part 20 together with the water are brought into the collar part 21 by running water. When cleaning is performed by collecting and depositing on the bottom and removing the lid portion 22 described above, it is only necessary to perform the cleaning operation centering on the collar portion 21, and the workability of the cleaning operation can be further enhanced.

  With the configuration as described above, the drainage systems A and A1 of the present invention are conventional even when rainwater or the like adheres to the outer surface of the sliding door 3 and flows down as it is and accumulates in the door support 1. The drainage to the drainage unit 2 can be naturally performed without performing the drainage work by the manual work. Thereby, while having a simple configuration, the work load of the drainage work can be reduced, and water overflows from the door support 1 or the door is opened for the drainage work to wet the indoor floor surface. Can be surely prevented.

  Moreover, even if impurities accumulate in the door support 1, such impurities are discharged together with the accumulated water to the drainage channel via the drainage unit 2. The cleaning work that has been performed for each of the drainage units 2 can be performed only by the drainage unit 2. Thereby, reduction of the work load by the cleaning work regarding the door support 1 can also be aimed at.
