Description

[Technical Field]

[0001] The present invention relates to a garbage collection vehicle, in particular a garbage collection vehicle comprising a garbage storage box mounted on the vehicle body, a garbage drop box supported at the upper rear end of the garbage storage box via a hinge shaft so that it can swing up and down, a garbage loading device arranged inside the garbage drop box and loading garbage put into the garbage drop box into the garbage storage box, and a hinge cover whose front end is attached to the rear part of the top surface of the garbage storage box and whose rear end is attached to the top surface of the garbage drop box, and which covers the hinge shaft and the gap between the garbage storage box and the garbage drop box from above. [Background technology]

[0002] The above-described garbage collection vehicle is well known, as shown in, for example, Patent Document 1. In the garbage collection vehicle of Patent Document 1, a hinge cover is used to protect the hinge shaft and surrounding components (such as various pipes) exposed in the gap between the garbage collection box and the garbage dump box from rainwater, dust, and the like. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Publication number 5-42962 Summary of the Invention [Problem to be solved by the invention]

[0004] In the refuse collection vehicle of Patent Document 1, if a problem occurs inside the refuse collection box or the refuse dump box, such as a fire, the hinge cover is opened and a fire extinguishing agent is poured into the gap between the two boxes. In this case, it is not easy to quickly open the hinge cover all the way, and if the hinge cover is opened all the way, the poured fire extinguishing agent is likely to scatter in excess in the surrounding area, which may make it difficult to carry out fire extinguishing activities efficiently.

[0005] The present invention has been made in view of the above circumstances, and has as its object to provide a garbage collection vehicle that can solve the above problems of conventional structures with a simple structure. [Means for solving the problem]

[0006] In order to achieve the above object, the present invention provides a garbage collection box mounted on a vehicle body, a garbage drop box supported at the upper rear end of the garbage collection box via a hinge shaft so as to be able to swing up and down, a garbage loading device disposed in the garbage drop box and loading garbage to be put into the garbage drop box into the garbage collection box, and a hinge cover having a front end attached to the rear part of the upper surface of the garbage collection box and a rear end attached to the upper surface of the garbage drop box, In a garbage collection vehicle, the hinge cover covers the hinge shaft and the gap between the garbage storage box and the garbage dump box from above, and has a first feature in that the hinge cover has a cover body with a hole in one part, a lid part that closes the hole, and a connector that detachably connects at least a part of the peripheral edge of the hole to a corresponding peripheral edge of the lid part, and the lid part can open at least a part of the hole by detaching the connector.

[0007] In addition to the first feature, the present invention has a second feature in that the connector is composed of a single linear fastener interposed between the peripheral edge of the hole and the peripheral edge of the cover, and at least the middle portion of the linear fastener is formed in an arc shape in the longitudinal direction.

[0008] In addition to the first feature, the present invention has a third feature in that the hinge cover has a pair of slits extending parallel to each other from the side edge on at least one of the left and right sides, the portion of the hinge cover sandwiched between the pair of slits forming the lid portion and the other portion forming the cover body, and the connector is composed of a pair of linear fasteners that detachably connect the pair of slits.

[0009] The present invention also provides a garbage collection vehicle comprising: a garbage collection box mounted on a vehicle body; a garbage dump box supported on the upper rear end of the garbage collection box via a hinge shaft so that it can swing up and down; a garbage loading device disposed within the garbage dump box and loading garbage dumped into the garbage dump box into the garbage collection box; and a hinge cover whose front end is attached to the rear part of the upper surface of the garbage dump box and whose rear end is attached to the upper surface of the garbage dump box, the hinge cover covering the hinge shaft and the gap between the garbage collection box and the garbage dump box from above. The fourth feature of the hinge cover is that it has a cover body having a hole in one part, a pair of lid parts that can close the hole, and a connector that detachably connects the two lid parts, and the lid parts can open at least a part of the hole by detaching the connector, and the hinge cover has a slit that extends inward from the side edge on at least one of the left and right sides, and the parts that turn up on both sides of the slit form the pair of lid parts, and the other parts form the cover body. [Effects of the Invention]

[0010] According to a first aspect of the present invention, a hinge cover for a garbage collection vehicle includes a cover body having a hole in a portion thereof, a lid portion that closes the hole, and a connector that detachably connects at least a portion of the periphery of the hole to a corresponding periphery of the lid portion. By disconnecting the connector, the lid portion can open at least a portion of the hole. In an emergency, the lid portion can open at least a portion of the hole by disconnecting the connection between the periphery of the hole in the cover body and the corresponding periphery of the lid portion with the connector. This allows the lid portion to open at least a portion of the hole in an emergency, such as in the event of a fire in a garbage collection box or a garbage dump box. Instead of opening the hinge cover entirely, only the portion of the hinge cover that is closed by the lid portion (i.e., the hole portion) can be opened, allowing a fire extinguishing agent to be rapidly injected into the fire area. Moreover, by opening only a portion of the hinge cover, unnecessary scattering of fire extinguishing agent can be effectively suppressed compared to when the hinge cover is fully opened, thereby enabling efficient firefighting efforts.

[0011] According to the second feature, the connector is composed of a single linear fastener interposed between the periphery of the hole and the periphery of the lid, and at least the middle portion of the linear fastener is formed in an arc shape along its length. This simplifies the connection structure and reduces costs. Moreover, when opening the lid, it is sufficient to cut off the single linear fastener, making the opening operation faster.

[0012] According to a third feature, the hinge cover has a pair of slits extending parallel to each other from at least one of the left and right side edges, the portion of the hinge cover sandwiched between the pair of slits forming the lid, and the remaining portion forming the cover body, and the connector is composed of a pair of wire fasteners that severably connect the pair of slits. As a result, even though there is only one pair of wire fasteners as connectors, they extend from the outer edge of the hinge cover, making them easy to sever from the outside of the trash bin, and because the routing path for each wire fastener is a relatively short, straight path, the ease of assembling the wire fasteners to the hinge cover and the ease of opening and closing the lid are excellent.

[0013] Furthermore, according to the fourth feature, similar to the effect of the first feature, in an emergency, for example, when a fire breaks out inside a garbage collection box or a garbage dump box, instead of opening the entire hinge cover, it is possible to open only a portion of the hinge cover that is covered by the lid (i.e., the hole portion), and from there, fire extinguishing agent can be quickly injected into the fire area.Furthermore, by opening only a portion of the hinge cover, it is possible to effectively prevent fire extinguishing agent from being scattered around unnecessarily compared to when the hinge cover is fully open, and fire extinguishing activities can be carried out efficiently. In particular, the hinge cover has a single slit extending inward from the side edge on at least one of the left and right sides, and the parts of the hinge cover that can be folded on both sides of the slit form a pair of lid sections, while the other parts form the cover body.Since the slit extends inward from the outer end of the hinge cover, not only does it make it easier to disconnect the connector from the outside of the garbage bin, but since it is only necessary to connect the connector to just one slit, the ease of assembling the connector to the hinge cover and the ease of opening and closing the lid are extremely good.

[0015] Hereinafter, an embodiment of the present invention will be described with reference to the accompanying drawings.

[0016] First, a garbage collection vehicle V of a first embodiment will be described with reference to Figures 1 to 6. The garbage collection vehicle V comprises a garbage collection box 10 mounted on a vehicle frame 1 as a vehicle body, a garbage drop box 20 supported at the upper rear end of the garbage collection box 10 via a pair of left and right hinge shafts 21 so as to be able to swing up and down, and a garbage loading device 30 disposed within the garbage drop box 20 and capable of loading garbage put into the garbage drop box 20 into the garbage collection box 10.

[0017] The hinge shaft 21 passes through a first hinge bracket 10b fixed to both left and right ends of the upper rear end of the garbage collection box 10, and a second hinge bracket 20b fixed to both left and right ends of the upper front end of the garbage dump box 20, and the first and second hinge brackets 10b, 20b are pivotally supported and connected to each other so that they can swing relative to each other, particularly at the outer axial half of the hinge shaft 21. The axial movement of the hinge shaft 21 relative to the first and second hinge brackets 10b, 20b is restricted by a stopper (for example, a circlip or locking pin that can be engaged and disengaged with the hinge shaft 21).

[0018] The trash collection box 10 is constructed by integrally joining a rear end frame 10a formed to outline the outer periphery of the rear end of a box-shaped collection box main body 10m with an open rear end, and the inner surface of the rear end frame 10a forms a rear end opening 10i of the trash collection box 10. Left and right reinforcing plates 15 that cover the upper left and right ends of the rear end frame 10a are joined (for example, welded) to the left and right ends of the upper end of the rear end frame 10a, and a first hinge bracket 10b is fixed (for example, welded) to each of the reinforcing plates 15 and the rear end frame 10a so as to straddle both of them.

[0019] Thus, the reinforcing plate 15 increases the support rigidity of the rear end frame 10a with respect to the hinge shaft 21 (and consequently the trash bin 20 and a pusher plate driving cylinder 32, which will be described later).

[0020] A pair of left and right tilting cylinders 12 are interposed between the garbage drop box 20 and the rear end frame 10a of the garbage collection box 10, and the extension and contraction of these tilting cylinders 12 allows the garbage drop box 20 to be forcibly swung up and down around the hinge shaft 21. This up and down swing allows the garbage drop box 20 to move between a normal use position (i.e., the travel position shown in Figures 1 and 2) in which it covers the rear end opening 10i of the garbage collection box 10, and an ejection position (i.e., the position shown in Figure 3) in which it tilts rearward and upward from there to widen the rear end opening 10i.

[0021] The tilting cylinder 12 is arranged along the outer surface of the trash bin body 20m of the trash bin 20, and is covered with fixed side covers 20c on the upper half of both the left and right sides of the trash bin body 20m.

[0022] When the garbage collection vehicle V, which has finished collecting waste, arrives at a waste treatment facility or waste collection site, the rear end opening 10i of the garbage storage box 10 is opened, for example, by swinging the garbage drop box 20 upward to the discharge position, and the waste in the garbage storage box 10 is discharged to a waste drop site such as a waste treatment facility.

[0023] In this case, waste can be discharged from the waste collection box 10 by dumping the waste collection box 10 with the front of the box raised using a conventionally known dump cylinder (not shown) provided between the waste collection box 10 and the vehicle frame F. Alternatively, waste can also be discharged from the waste collection box 10 by operating a conventionally known forced discharge device (not shown) installed in the waste collection box 10.

[0024] Although not shown, the rear surface of the garbage bin 20 is provided with an inlet through which waste can be thrown into the garbage bin 20 and a door that can open and close the inlet as desired. The structures and functions of the inlet and door are well known.

[0025] The garbage loading device 30 also includes a push plate 31 housed in the upper part of the garbage dump box 20 and pivoted 31p at its middle part on the left and right side walls of the dump box main body 20m of the garbage dump box 20, allowing it to swing back and forth, a cylinder 32 that drives the push plate 31 to swing, a rotating plate 33 located below the push plate 31 and pivoted 33p on the left and right side walls of the dump box main body 20m, and a rotation drive unit (not shown) arranged on one of the left and right sides of the dump box main body 20m to rotate the rotating plate 33.

[0026] 6, the base end of the cylinder 32 is disposed adjacent to the inner side of the second hinge bracket 20b, and is rotatably fitted and supported on the inner half of the axial direction of the hinge shaft 21. The tip end of the cylinder 32 is rotatably supported and connected to the upper end of the push plate 31.

[0027] The trash thrown into the trash dump box 20 is then scraped up by the rotating plate 33 and further pushed into the trash collection box 10 by the pusher plate 31. This scraping and pushing action of trash is well known in the art.

[0028] The garbage loading device 30 is not limited to the embodiment. For example, a garbage loading device (see, for example, Japanese Patent Application Laid-Open No. 2010-241553) may be provided which includes a lift plate supported on the left and right side walls of the input box body 20m in a forward tilted position so as to be vertically slidable, a cylinder for driving the lift plate to move up and down, a push plate pivotally supported on the lower part of the lift plate so as to be swingable back and forth, and a cylinder for driving the swing of the push plate, and which combines the lifting and lowering of the lift plate with the swinging back and forth of the push plate to compress the input garbage and push it into the garbage storage box 10. The above-mentioned conventional garbage loading device (see Japanese Patent Publication No. 2003-200416) may be substituted for the garbage loading device 30 of the embodiment.

[0029] The hinge cover C is formed in a roughly rectangular sheet shape from a flexible and waterproof material (for example, cloth, rubber, synthetic resin, etc.), and its front end Cf is attached to the rear part of the top surface of the trash collection box 10, and its rear end Cr is attached to the front part of the top surface of the trash drop box 20. The hinge cover C is intended to cover from above the horizontally long, open-topped gap S formed between the upper rear end of the trash collection box 10 and the upper front end of the trash drop box 20.

[0030] In this gap S, a plurality of hydraulic pipes 38 extending from the ceiling of the garbage collection box 10 toward the hydraulic equipment inside the garbage dump box 20 (i.e., the tilting cylinder 12 and the cylinder 32 of the garbage loading device 30, etc.) and the aforementioned hinge shaft 21 are exposed. By covering the gap S from above, the hinge cover C protects the hinge shaft 21 and the hydraulic pipes 38 from rainwater, dust, sunlight, etc. In Fig. 6, in order to clearly show the gap S, a portion of the right side of the hinge cover C is broken away to show the fixtures and the like behind the hinge cover C, but the actual front and rear side edges and right side edge of the hinge cover C are simply shown by two-dot chain lines.

[0031] To attach the hinge cover C, for example, the underside of the thick front end Cf of the hinge cover C is overlapped with the reinforcing plate 15 and rear end frame 10a of the trash collection box 10, with a band-shaped washer 26 sandwiched between them, and the hinge cover is detachably joined with multiple sets of bolts 18 and weld nuts 19 (the weld nuts 19 are fixed to the underside of the upper part of the rear end frame 10a) that penetrate the overlapping portions Cf, 26, 15, 10a at intervals. On the other hand, the underside of the thick rear end Cr of the hinge cover C is overlapped with the upper surface of the upper wall portion 20a of the trash bin 20, with a band-shaped washer 27 sandwiched between them, and the hinge cover is detachably joined with multiple sets of bolts 28 and weld nuts 29 (the weld nuts 29 are fixed to the underside of the upper wall portion 20a) that penetrate the overlapping portions Cr, 27, 20a at intervals.

[0032] Furthermore, the front end Cf and rear end Cr of the hinge cover C may be connected to the garbage collection box 10 and the garbage drop box 20, respectively, using removable connecting means other than the bolts 18, 28 and the weld nuts 19, 29 (e.g., snap buttons, elastic clips, etc.).

[0033] As can be seen in Figure 6, the hinge cover C has a cover main body Cm having a hole Cmh in a portion thereof, a lid portion Ct that covers the hole Cmh, and a single wire fastener F as a connecting device that detachably connects at least a portion of the peripheral edge of the hole Cmh to the corresponding peripheral edge of the lid portion Ct.

[0034] More specifically, the hinge cover C has a U-shaped slit L on one of the left and right sides (the left side in this embodiment) of the hinge cover C, and the U-shaped tongue portion surrounded by the slit L forms the lid portion Ct, while the other portion (i.e., other than the lid portion Ct) forms the cover main body Cm. In other words, the slit L corresponds to the periphery of the hole Cmh and the corresponding periphery of the lid portion Ct.

[0035] In this embodiment, a single linear fastener F is used as a connector that connects the above-mentioned slit L (i.e., the peripheral edge of the hole Cmh and the corresponding peripheral edge of the lid portion Ct) in a manner that allows the slit L to be severed at any time, and by severing the linear fastener F, the lid portion Ct can open at least a portion of the hole Cmh.

[0036] The linear fastener F mainly comprises a first tape having many first fastener teeth 41 in the longitudinal direction and fixed along the periphery of the hole Cmh, a second tape having many second fastener teeth 42 in the longitudinal direction and fixed along the periphery of the lid portion Ct, and a slider 40 that slides across the first and second fastener teeth 41, 42 to open and close the space between the first and second fastener teeth 41, 42, and the opening and closing functions of the linear fastener F are well known. Note that the first and second tapes are well known and are therefore not shown in FIG. 6.

[0037] Moreover, the linear fastener F in the first embodiment is formed so that the front half Fa extends in a semicircular arc shape that convexly protrudes forward, and the rear half Fb extends linearly rearward from the rear ends (both ends) of the semicircular arc portion, but in the present invention, it is sufficient if at least the middle portion is formed in an arc shape, and the orientation of the linear fastener F (slit L) is not limited to that in the first embodiment. For example, it is also possible to implement a modified example in which the orientation of the linear fastener F (slit L) in the first embodiment is rotated by a predetermined angle (e.g., 60 degrees, 90 degrees, 180 degrees, 270 degrees, etc.).

[0038] Furthermore, both ends of a tensioner 25 are fixed to the top of the trash bin 20 to apply a predetermined tension to the hinge cover C when the trash bin 20 is in the normal use position (FIGS. 1 and 4) to prevent the hinge cover C from loosening. The middle part of this tensioner 25 extends in the left-right direction of the trash bin 20, and has a tension applying part 25a that abuts against the hinge cover C at a position higher than the top surface of the trash bin 20.

[0039] In the example shown in Figure 4, the tensioning portion 25a of the tensioner 25 is shown to extend forward and sideways from the support frame 24 protruding from the top surface of the garbage bin 20, but as in the modified example shown in Figure 8, the tensioning portion 25a of the tensioner 25 may also extend upward from the top surface of the garbage bin 20.

[0040] Next, the operation of the first embodiment will be described. In the garbage collection vehicle V, a horizontally long, open-topped gap S is formed between the upper rear end of the garbage collection box 10 and the upper front end of the garbage drop box 20, and this gap S is normally covered from above by a hinge cover C. Therefore, the hinge cover C protects the hinge shaft 21 and hydraulic piping group 38 exposed in the gap S from rainwater, sunlight, etc. Furthermore, since the hinge cover C is flexible, the garbage contained in the garbage collection box 10 can be easily removed. of When the trash bin 20 is tilted upward and rearward for disposal, the hinge cover C can bend and deformed without any strain, as is clear from FIGS.

[0041] Incidentally, during garbage collection operations using a garbage collection vehicle V, there is a possibility that a fire may break out inside the garbage collection box 10 or the garbage dump box 20 due to ignition of the dumped garbage, etc. In this case, in the past, the front end Cf or rear end Cr of the hinge cover C would be removed and the hinge cover C would be fully opened, and then the tip of a fire hose would be directed into the gap S between the upper rear end of the garbage collection box 10 and the upper front end of the garbage dump box 20, and a fire extinguishing agent would be poured into the gap from the tip of the hose, but the task of quickly and fully opening the hinge cover C is not easy in practice, and if the hinge cover C were to be fully opened, there would be the inconvenience that the poured fire extinguishing agent would easily splash in excess around.

[0042] In contrast, the hinge cover C of the embodiment has a cover main body Cm having a hole Cmh in a portion thereof, a lid portion Ct that covers the hole Cmh, and a linear fastener F as a connecting device that detachably connects at least a portion of the peripheral edge of the hole Cmh to a corresponding peripheral edge of the lid portion Ct, and by detaching the linear fastener F, the lid portion Ct can quickly and easily open at least a portion of the hole Cmh.

[0043] In this way, when a fire breaks out inside the garbage collection box 10 or the garbage dump box 20, instead of opening the hinge cover C entirely, only the part that is covered by the lid part Ct (i.e., the part of the hole Cmh) can be opened and the tip of the fire hose (in FIG. 6, only the cross section of the hose tip is shown simply by the reference numeral 50) can be inserted through the hole Cmh into the gap S, making it possible to quickly inject fire extinguishing agent into the area of ​​the fire. Moreover, by opening only part of the hinge cover C, it is possible to effectively prevent fire extinguishing agent from being scattered around unnecessarily compared to when the hinge cover C is completely open.

[0044] In particular, the connector of the first embodiment is composed of a single linear fastener F interposed between the peripheral edge of the hole Cmh and the peripheral edge of the lid portion Ct, and at least the middle portion of the linear fastener F is formed in an arc shape in the longitudinal direction. This means that only one linear fastener F is required to connect the peripheral edge of the hole Cmh and the corresponding peripheral edge of the lid portion Ct, thereby simplifying the connection structure and reducing costs. Moreover, when opening the lid portion Ct, it is sufficient to cut off only the single linear fastener F, making the opening operation faster.

[0045] 7 shows a second embodiment. The hinge cover C of this second embodiment has a pair of slits L1, L2 extending parallel to each other from at least one of the left and right side edges (the left edge in this embodiment). The portion of the hinge cover C sandwiched between the pair of slits L1, L2 constitutes the lid portion Ct, and the remaining portion constitutes the cover main body Cm. A pair of linear fasteners F1, F2 extending parallel to each other are used as a pair of connectors that detachably connect the pair of slits L1, L2, respectively.

[0046] Although not shown, instead of or in addition to the above-described structure of the second embodiment, the hinge cover C may be provided with a pair of slits L1, L2 extending parallel to each other from its right edge, and the pair of slits L1, L2 may be connected in a detachable manner by a pair of linear fasteners F1, F2, respectively.

[0047] Other configurations of the second embodiment are similar to those of the first embodiment, so the components of the second embodiment are simply given the same reference numerals as the corresponding components of the first embodiment, and further structural explanations will be omitted.

[0048] Therefore, the second embodiment can achieve basically the same effects as the first embodiment.

[0049] In particular, the linear fasteners F1, F2 of the second embodiment, even though there is only one pair, extend from the outer end (one of the left and right side ends) of the hinge cover C, which has the advantage that workers can easily perform disconnection and connection operations from the outside of the garbage bin 20. Furthermore, the route for each linear fastener F1, F2 is a relatively short, straight path, and disconnection and connection operations can be performed by simultaneously sliding the sliders 40 of both linear fasteners F1, F2 in the same direction. This improves the ease of assembling the linear fasteners F1, F2 to the hinge cover C and the ease of opening and closing the lid portion Ct.

[0050] Figure 9 also shows the hinge cover C of the third embodiment in a standalone state, with (a) showing the state in which the line fastener F3 is closed, and (b) showing the state in which the line fastener F3 is open and the lid portion Ct is open.

[0051] Thus, the hinge cover C of the third embodiment has a cover main body Cm having a hole Cmh in a portion thereof, a pair of lid portions Ct' that can cover the hole Cmh, and a connecting device F3 that detachably connects the two lid portions Ct', and by detaching the connecting device F3, the lid portion Ct' can open at least a portion of the hole Cmh.

[0052] Moreover, the hinge cover C of this third embodiment has a slit L3 that extends linearly inward from at least one of the left and right side edges (the left edge in the third embodiment), and the roughly triangular portions of the hinge cover C that turn on both sides of the slit L3 constitute a pair of lid portions Ct, while the remaining portions constitute the cover main body Cm. The connector between the two lid portions Ct' is made up of a single linear fastener F3 that severably connects the slit L3.

[0053] Therefore, in the event of a fire in a garbage bin 20 or the like, the linear fastener F3 is opened to separate the pair of lid portions Ct, and then a portion of each lid portion Ct' is picked up and, for example, rolled up upward, thereby opening both lid portions Ct and widening the hole Cmh as shown in Figure 9(b).As a result, as in the first and second embodiments, the tip 50 of the fire hose can be inserted through the hole Cmh toward the gap S, and fire extinguishing agent can be quickly injected into the fire area.

[0054] Other configurations of the third embodiment are similar to those of the first and second embodiments, so the components of the third embodiment are simply given the same reference numerals as the corresponding components of the first and second embodiments, and further structural explanations will be omitted.

[0055] In addition, in FIG. 9, the third embodiment shows only the hinge cover C by itself, but the mounting structure of this hinge cover C to the refuse collection vehicle V is the same as in the first and second embodiments.

[0056] Therefore, the third embodiment can achieve basically the same effects as the second embodiment.

[0057] In particular, the slit L3 in the third embodiment extends from the outer end (one of the left or right side ends) of the hinge cover C, which not only has the advantage of making it easier for workers to disconnect and connect the line fastener F3 from the outside of the garbage bin 20, but also because only one line fastener F3 is required as a connecting device, the ease of assembling the line fastener F3 to the hinge cover C and the ease of opening and closing the lid portion Ct are extremely good.

[0058] Although the embodiments of the present invention have been described above, the present invention is not limited to the above-described embodiments, and various design modifications can be made without departing from the present invention as set forth in the claims.

[0059] For example, in the first and second embodiments, fasteners F, F1, and F2 consisting of linear fasteners (also called zippers or chucks) are exemplified as connectors for connecting between the peripheral edge of the hole Cmh in the hinge cover C and the corresponding peripheral edge of the lid portion Ct, but the connectors relating to the first feature of the present invention are not limited to the embodiments, and other fasteners, such as snap buttons (point fasteners) or hook-and-loop fasteners, may also be used.

[0060] Furthermore, in the first embodiment, one hole Cmh is provided on one of the left and right sides (i.e., the left side) of the hinge cover C, but multiple (at least two) holes Cmh may be provided in multiple locations on the hinge cover C. In this case, if holes Cmh that are opened and closed by the lid part Ct are provided not only on the left side but also on the right side of the hinge cover C, it is convenient because workers can open the lid part Ct from either the left or right side to perform fire-fighting work.

[0061] In addition, in the third embodiment, a fastener F3 consisting of a line fastener (also called a zipper or chuck) is exemplified as a connecting device that detachably connects a pair of lid portions Ct' that can block the hole Cmh in the hinge cover C. However, the connecting device related to the fourth feature of the present invention is not limited to the embodiment, and other fasteners, such as a snap button (point fastener) or a hook-and-loop fastener, may be used to connect the slit L3.
