Publication No. 5-42962

In the garbage collection vehicle of Patent Document 1, when a trouble such as a fire occurs inside the garbage storage box or the garbage input box, 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 open all the hinge covers quickly, and if the hinge covers are opened completely, the extinguishing agent that has been put in is likely to scatter around, making firefighting operations more efficient. There is a possibility that it cannot be done.

The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a garbage collection vehicle that can solve the above-mentioned problems of the conventional structure with a simple structure.

In order to achieve the above object, the present invention includes a garbage storage box mounted on a vehicle body, a garbage input box supported vertically swingably via a hinge shaft at the upper rear end of the garbage storage box, a garbage loading device disposed in the garbage input box to load the garbage into the garbage storage box; a hinge cover whose rear end is attached to the top surface of the box; the hinge cover covers the hinge shaft and the gap between the garbage storage box and the garbage input box from above; The cover includes a cover body that partially has a hole, a lid portion that closes the hole, and a connector that connects a peripheral edge of at least a portion of the hole and a corresponding peripheral edge of the lid portion in a separable manner. The first feature is that the lid part can open at least a part of the hole by the disconnection of the connector.

Further, in addition to the first feature, the present invention provides that the connecting tool is constituted by a single wire fastener interposed between the peripheral edge of the hole and the peripheral edge of the lid, and A second feature of the wire fastener is that at least the middle portion thereof is formed in an arc shape in the length direction.

Further, in addition to the first feature, the present invention provides that the hinge cover has a pair of cuts extending in parallel with each other from at least one side edge of the left and right sides of the hinge cover, and The portion sandwiched between the cuts constitutes the lid portion, and the other portion constitutes the cover body, and the connecting tool includes a pair of wire fasteners that releasably connect the pair of cuts. The third feature is that

The present invention also provides a garbage storage box mounted on a vehicle body, a garbage input box supported vertically swingably at the upper rear end of the garbage storage box via a hinge shaft, and a garbage storage box disposed within the garbage input box. a garbage loading device for loading garbage into the garbage storage box; a front end portion is attached to the upper rear portion of the garbage storage box; A garbage collection vehicle is provided with a hinge cover to which the hinge shaft is attached, and the hinge cover covers the gap between the hinge shaft and the garbage storage box and the garbage input box from above, the hinge cover has a hole in a part. a pair of lids that can close the hole, and a connector that connects the two lids in a separable manner, and when the connector is separated, the lid closes to the hole. At least a portion of the hinge cover can be opened, and the hinge cover has a single cut extending inward from at least one side edge of the left and right sides of the hinge cover, and the hinge cover can be rolled up on both sides at the cut. A fourth feature is that the portions of the cover constitute the pair of lid portions, and the other portion constitutes the cover body.

According to a first feature of the present invention, a hinge cover for a garbage collection vehicle includes a cover main body that partially has a hole, a lid portion that closes the hole, and a correspondence between the peripheral edge of at least a portion of the hole and the lid portion. and a connecting tool that connects the peripheral edge of the cover body in a separable manner, and by separating the connecting tool, the lid part can open at least a part of the hole, so that in an emergency, the hole in the cover body can be opened. By separating the connecting portion between the peripheral edge and the corresponding peripheral edge of the lid using a connecting tool, the lid can open at least a portion of the hole. As a result, in an emergency, for example, in the event of a fire occurring inside the garbage storage box or garbage disposal box, instead of opening the hinge cover completely, you can open only the part that is covered by the lid (i.e. the hole part) and then open the hinge cover from there. It becomes possible to quickly inject extinguishing agent into the fire area. Furthermore, by opening only a portion of the hinge cover, it is possible to more effectively suppress the wasteful scattering of extinguishing agent into the surrounding area than when the hinge cover is fully opened, and it is possible to carry out fire extinguishing activities more efficiently.

According to a second feature, the connector comprises a single wire fastener interposed between the peripheral edge of the hole and the peripheral edge of the lid, the wire fastener being Since at least the intermediate portion is formed in an arc shape, only a single wire fastener as a connecting device is required, which simplifies the connecting structure and further reduces costs. Moreover, when opening the lid part, it is sufficient to cut off a single wire fastener, and the opening operation can be performed more quickly.

According to the third feature, the hinge cover has a pair of cuts extending in parallel with each other from at least one side edge of the left and right sides of the hinge cover, and the hinge cover is sandwiched between the pair of cuts of the hinge cover. The portion constitutes the lid portion, and the other portion constitutes the cover body, and the connecting tool is constituted by a pair of wire fasteners that connect the pair of cuts in a separable manner. As a result, even if there is a pair of wire fasteners as connecting devices, they extend from the outside edge of the hinge cover, making it easier to disconnect from the outside of the garbage disposal box, and furthermore, each wire fastener has a routing path. Since this is a relatively short straight path, the workability of assembling the wire fastener to the hinge cover and the operability of opening and closing the lid are excellent.

Also, according to the fourth feature, similar to the effect of the first feature, in an emergency, for example, when a fire occurs in the garbage storage box or garbage disposal box, the hinge cover is not completely opened but is closed by the lid. By opening only a portion (i.e., the hole), it is possible to quickly inject extinguishing agent into the fire area, and by opening only a portion of the hinge cover, the amount of extinguishing agent can be injected quickly compared to when the hinge cover is opened completely. It is possible to effectively suppress wasteful scattering in the surrounding area, and it is possible to carry out fire extinguishing activities efficiently. In particular, the hinge cover has a single cut extending inward from the side edges on at least one of the left and right sides of the hinge cover, and the portion of the hinge cover that can be rolled up on both sides with the cut as a border is a pair of lid parts. In addition, since the other parts constitute the cover body, the cut extends inward from the outer edge of the hinge cover, making it easier to disconnect the connector from the outer side of the garbage disposal box. Alternatively, it is sufficient to connect only one cut with a connecting tool, which improves the workability of assembling the connecting tool to the hinge cover and the operability of opening and closing the lid.

Embodiments of the present invention will be described below based on the accompanying drawings.

First, a garbage collection vehicle V according to a first embodiment will be described with reference to FIGS. 1 to 6. The garbage collection vehicle V includes a garbage storage box 10 mounted on a vehicle body frame 1 as a vehicle body, and is supported so as to be vertically swingable via a pair of left and right hinge shafts 21 at the upper rear end of the garbage storage box 10. This device includes a garbage input box 20 and a garbage loading device 30 which is disposed inside the garbage input box 20 and can load the input garbage into the garbage input box 20 into the garbage storage box 10.

The hinge shaft 21 includes a first hinge bracket 10b fixed to both left and right ends of the upper rear end of the garbage storage box 10, and a second hinge bracket 20b fixed to both left and right ends of the upper front end of the garbage storage box 20, respectively. The first and second hinge brackets 10b and 20b are pivotally supported and connected to each other so as to be able to swing relative to each other, particularly in the axially outer half of the hinge shaft 21. The axial movement of the hinge shaft 21 with respect to the first and second hinge brackets 10b and 20b is restricted by a stopper (for example, a circlip, a locking pin, etc. that is removable from the hinge shaft 21).

The garbage storage box 10 is constructed by integrating a rear end frame 10a formed to frame the outer periphery of the rear end with the rear end of the storage box main body 10m, which has a box shape with an open rear end. The inner surface of the frame 10a forms a rear end opening 10i of the garbage storage box 10. Right and left reinforcing plates 15 that cover these from above are joined (for example, welded) to both the left and right ends of the upper end of the rear end frame 10a, and each of the reinforcing plates 15 and the rear end frame 10a are connected to each other by straddling both of them. The first hinge bracket 10b is fixed (for example, welded) so that the first hinge bracket 10b is bent.

Thus, the reinforcing plate 15 increases the support rigidity of the rear end frame 10a to the hinge shaft 21 (and by extension, the garbage input box 20 and the pushing plate driving cylinder 32, which will be described later).

A pair of left and right tilting cylinders 12 are interposed between the garbage input box 20 and the rear end frame 10a of the garbage storage box 10, and the expansion and contraction of the tilting cylinders 12 forces the garbage input box 20 around the hinge shaft 21. It is possible to swing vertically. By swinging up and down, the garbage input box 20 can be moved between the normal use position (i.e., the traveling position shown in FIGS. 1 and 2) covering the rear end opening 10i of the garbage storage box 10, and from there, the garbage input box 20 can be tilted rearward upward to open the rear end opening 10i. 10i is movable between a wide open ejection position (ie, the illustrated position in FIG. 3).

Incidentally, the tilting cylinder 12 is arranged along the outer surface of the input box body 20m of the garbage input box 20, and is covered with side covers 20c fixed to the upper halves of both left and right sides of the input box body 20m.

When the garbage collection vehicle V that has finished collecting waste arrives at the waste treatment facility or waste collection site, the garbage storage box 10 is opened by, for example, swinging the garbage input box 20 upward to the discharge position. The rear end opening 10i is opened to discharge the waste in the garbage storage box 10 to a waste input location such as a waste treatment facility.

In this case, the waste can be discharged from inside the garbage storage box 10 by dumping the garbage storage box 10 forward and upward using a conventionally well-known dump cylinder (not shown) provided between the garbage storage box 10 and the vehicle body frame F. It is possible. Alternatively, the waste can be discharged from the garbage storage box 10 by operating a conventionally known forced discharge device (not shown) installed inside the garbage storage box 10.

Although not shown, the rear surface of the garbage input box 20 is provided with an input port into which waste is to be input into the garbage input box 20, and a door that can open and close the input port as desired. Incidentally, the structures and functions of these input ports and doors are conventionally well known.

Further, the garbage loading device 30 includes a push plate 31 which is housed in the upper part of the garbage input box 20 and whose intermediate portion is pivoted 31p on the left and right side walls of the input box main body 20m of the garbage input box 20, so that it can swing back and forth. A cylinder 32 that swings and drives the push plate 31, a rotary plate 33 located below the push plate 31 and rotatably supported by a shaft 33p on the left and right side walls of the input box main body 20m; It also includes a rotary drive device (not shown) disposed on one left and right side of the input box main body 20m.

As is clear from FIG. 6, the base end of the cylinder 32 is arranged adjacent to the inner side of the second hinge bracket 20b, and is rotatable to the axially inner half of the hinge shaft 21. mated and supported. Further, the distal end of the cylinder 32 is rotatably supported and connected to the upper end of the pushing plate 31.

Then, the garbage thrown into the garbage input box 20 is scraped up by the rotary plate 33 and further pushed into the garbage storage box 10 by the pushing plate 31. This dust scraping and pushing action is well known in the art.

Note that the garbage loading device 30 is not limited to the embodiment. For example, there is a lift plate that is supported on the left and right side walls of the 20 m body of the input box so that it can slide up and down in a forward-leaning position, a cylinder that drives the lift plate to move up and down, and a pusher that is pivotally supported at the bottom of the lift plate so that it can swing back and forth. This type is equipped with a plate and a cylinder for swinging the pushing plate, and combines the lifting and lowering of the lift plate with the back and forth swinging of the pushing plate to compress the input garbage and push it into the garbage storage box 10. Garbage loading device (for example, JP 2010-241553
(see Japanese Patent Publication) may be implemented instead of the garbage loading device 30 of the embodiment.

By the way, the hinge cover C is formed into a roughly rectangular sheet shape made of a flexible and waterproof material (for example, cloth material, rubber material, synthetic resin material, etc.), and the front end Cf of this is formed on the upper surface of the garbage storage box 10. The rear end portion Cr is attached to the front portion of the upper surface of the garbage input box 20. The hinge cover C is for covering from above a horizontally long and open-topped gap S formed between the upper rear end of the garbage storage box 10 and the upper front end of the garbage input box 20.

In the gap S, a plurality of hydraulic piping groups 38 extend from the ceiling of the garbage storage box 10 toward the hydraulic equipment in the garbage input box 20 (i.e., the above-mentioned tilting cylinder 12, the cylinder 32 of the garbage loading device 30, etc.). Also, the aforementioned hinge shaft 21 is exposed. The hinge cover C protects the hinge shaft 21 and the hydraulic piping group 38 from rainwater, dust, sunlight, etc. by covering the gap S from above. In FIG. 6, in order to clearly show the gap S, a part of the right side of the hinge cover C is cut away to show the equipment on the back side of the hinge cover C, but the front side of the actual hinge cover C is shown. - The rear edge and the right edge are simply indicated by two-dot chain lines.

In order to attach this hinge cover C, for example, the thick front end Cf of the hinge cover C is connected to the reinforcing plate 15 of the garbage storage box 10 and the rear end frame 10a by sandwiching the strip-shaped washer 26 between the lower surfaces of the thick front end Cf of the hinge cover C. It can be attached and detached using multiple sets of bolts 18 and weld nuts 19 (the weld nuts 19 are fixed to the upper and lower surfaces of the rear end frame 10a), which are overlapped with each other and pass through the overlapped portions Cf, 26, 15, and 10a at intervals. is combined with On the other hand, the thick rear end portion Cr of the hinge cover C has its lower surface overlapped with the upper surface of the upper wall portion 20a of the garbage input box 20 with the strip washer 27 in between, and the overlapping portion Cr, 27, They are removably connected by a plurality of sets of bolts 28 and weld nuts 29 (the weld nuts 29 are fixed to the lower surface of the upper wall portion 20a) passing through the upper wall portion 20a at intervals.

Note that the front end Cf and rear end Cr of the hinge cover C are connected to the garbage storage box 10 and the rear end Cr using a removable coupling means other than the bolts 18 and 28 and the weld nuts 19 and 29 (for example, a snap button, an elastic clip, etc.). They may be coupled to the garbage input box 20, respectively.

By the way, as is clear from FIG. 6, the hinge cover C has a cover main body Cm having a hole Cmh in a part, a lid part Ct that closes the hole Cmh, and a correspondence between the peripheral edge of at least a part of the hole Cmh and the lid part Ct. It has a single wire fastener F as a connecting tool that connects the peripheral edge of the wire in a separable manner.

To explain more specifically, the hinge cover C has a single U-shaped cut L on one left and right side of the hinge cover C (in the embodiment, the left side), and the hinge cover C has a U-shaped cut L that is surrounded by the cut L. The U-shaped tongue portion constitutes the lid portion Ct, and the other portions (that is, other than the lid portion Ct) constitute the cover main body Cm. That is, the cut L corresponds to the peripheral edge of the hole Cmh and the corresponding peripheral edge of the lid part Ct.

In this embodiment, a single wire fastener F is used as a connecting tool that connects the cut L (that is, the peripheral edge of the hole Cmh and the corresponding peripheral edge of the lid part Ct) so that they can be separated at any time. By separating the wire fastener F, the lid Ct can open at least a portion of the hole Cmh.

The wire fastener F includes a first tape having a large number of first fastener teeth 41 in the longitudinal direction and fixed along the peripheral edge of the hole Cmh, and a large number of second fastener teeth 42 in the longitudinal direction to attach the lid. A second tape fixed along the peripheral edge of the portion Ct, and a slider 40 that can open and close between the first and second fastener teeth 41 and 42 by sliding across them so as to straddle them. The opening and closing functions thereof are well known in the art. Note that since the first and second tapes are conventionally well known, illustration thereof is omitted in FIG.

Moreover, the wire fastener F of the first embodiment is formed such that the front half Fa extends in a convex semicircular arc shape toward the front, and the rear half Fb extends linearly rearward from the rear end (both ends) of the semicircular arc shape. However, in the present invention, at least the intermediate portion may be formed in an arc shape, and the direction of the wire fastener F (cut L) is not limited to that in the first embodiment. For example, it is also possible to implement a modified example in which the direction of the wire fastener F (cut L) of the first embodiment is set to be rotated by a predetermined angle (for example, 60 degrees, 90 degrees, 180 degrees, 270 degrees, etc.). be.

Furthermore, a tensioner is provided on the upper part of the garbage input box 20 to apply a predetermined tension to the hinge cover C so as not to loosen the hinge cover C when the garbage input box 20 is in the normal use position (FIGS. 1 and 4). Both ends of 25 are fixed. The intermediate portion of the tensioner 25 extends in the left-right direction of the garbage input box 20, and has a tension applying portion 25a that comes into contact with the hinge cover C at a position higher than the upper surface of the garbage input box 20.

In the illustrated example of FIG. 4, the tension applying portion 25a of the tensioner 25 is projected sideways forward from the support frame 24 protruding from the upper surface of the garbage disposal box 20, but the modification illustrated in FIG. As in the example, the tension applying portion 25a of the tensioner 25 may be made to protrude upward from the upper surface of the garbage input box 20.

Next, the operation of the first embodiment will be explained. In the garbage collection vehicle V, a horizontally long and open-top gap S is formed between the rear upper end of the garbage storage box 10 and the front upper end of the garbage input box 20, but the gap S is normally closed upward by a hinge cover C. covered from. Therefore, the hinge shaft 21 and the hydraulic piping group 38 exposed in the gap S are protected by the hinge cover C from rainwater, sunlight, and the like. Furthermore, since the hinge cover C has flexibility, when the garbage input box 20 is tilted rearward and upward in order to discharge the garbage stored in the garbage storage box 10, the hinge cover C is moved as shown in FIGS. It can be bent and deformed easily.

By the way, during the garbage collection work by the garbage collection vehicle V, there is a possibility that a fire may occur inside the garbage storage box 10 or the garbage input box 20 due to ignition of the input garbage. In this case, in the past, after removing the front end Cf or rear end Cr of the hinge cover C and opening the hinge cover C completely, the space between the rear upper end of the garbage storage box 10 and the front upper end of the garbage input box 20 was removed. The tip of the fire hose is directed toward the gap S between the holes, and the fire extinguishing agent is injected from the tip of the hose. If C is fully opened, there is a problem in that the added extinguishing agent tends to scatter excessively into the surrounding area.

On the other hand, the hinge cover C of the embodiment includes a cover main body Cm having a hole Cmh in a part, a lid portion Ct that closes the hole Cmh, and a peripheral edge of at least a portion of the hole Cmh and a corresponding peripheral edge of the lid portion Ct. The cover Ct has a wire fastener F as a connector that connects the hole Cmh in a separable manner, and by separating the wire fastener F, the lid Ct can quickly and easily open at least a portion of the hole Cmh.

In this way, when a fire occurs in the garbage storage box 10 or the garbage input box 20, the hinge cover C is not opened completely, but only the part covered by the lid part Ct (that is, the part of the hole Cmh) is opened. Since the tip of the fire hose (in FIG. 6, only the cross section of the hose tip is simply indicated by reference numeral 50) can be inserted through the hole Cmh toward the gap S, extinguishing agent can be quickly injected into the fire area. becomes. Furthermore, by opening only a portion of the hinge cover C, it is possible to more effectively suppress the extinguishing agent from being wasted and scattered around than when the hinge cover C is fully opened.

In particular, the connector of the first embodiment is composed of a single wire fastener F interposed between the peripheral edge of the hole Cmh and the peripheral edge of the lid part Ct, and the wire fastener F has a length of At least the intermediate portion is formed in an arc shape in the direction. As a result, it is sufficient to prepare only one wire fastener F for connecting the peripheral edge of the hole Cmh and the corresponding peripheral edge of the lid part Ct, which simplifies the connection structure and further reduces costs. It will be done. Moreover, when opening the lid part Ct, it is sufficient to cut off a single wire fastener F, and the opening operation can be performed more quickly.

By the way, FIG. 7 shows a second embodiment. The hinge cover C of the second embodiment has a pair of cuts L1 and L2 extending parallel to each other from at least one of the left and right side edges (the left edge in the embodiment). The portion of the hinge cover C sandwiched between the pair of cuts L1 and L2 constitutes the lid portion Ct, and the other portion constitutes the cover body Cm. A pair of wire fasteners F1 and F2 extending parallel to each other is used as a pair of connectors that releasably connect the pair of cuts L1 and L2, respectively.

Although not shown, instead of/in addition to the above structure of the second embodiment, the hinge cover C is provided with a pair of cuts L1 and L2 extending in parallel from the right edge of the hinge cover C. The cuts L1 and L2 may be separably connected by a pair of wire fasteners F1 and F2, respectively.

The other configurations of the second embodiment are the same as those of the first embodiment. Therefore, each component of the second embodiment is given the same reference numeral as the corresponding component of the first embodiment, and further structural explanation will be omitted.

Thus, the second embodiment can achieve basically the same effects as the first embodiment.

In particular, the wire fasteners F1 and F2 of the second embodiment, even if there is a pair thereof, extend from the outer edge (one left and right side edge) of the hinge cover C, so that the worker can perform the separation operation from the outer side of the garbage disposal box 20. This has the advantage of making connection work easier. In addition, the routing path of each of the wire fasteners F1 and F2 is a relatively short straight path, and the sliders 40 of both wire fasteners F1 and F2 can be slid in the same direction at the same time to perform separation or connection work. It becomes possible. Therefore, the ease of assembling the wire fasteners F1 and F2 to the hinge cover C and the operability of opening and closing the lid portion Ct are good.

Further, FIG. 9 shows the hinge cover C of the third embodiment in an independent state, in particular, (a) shows the state with the wire fastener F3 closed, and (b) shows the lid part with the wire fastener F3 opened. This shows the state in which Ct is open.

Thus, the hinge cover C of the third embodiment has a cover main body Cm having a hole Cmh in a part, a pair of lid parts Ct' that can close the hole Cmh, and both lid parts Ct' can be separated. The cover Ct' can open at least a portion of the hole Cmh by disconnecting the connector F3.

Moreover, the hinge cover C of the third embodiment has a single cut L3 extending linearly inward from at least one side edge of the left and right sides (the left edge in the third embodiment). The substantially triangular portions of the hinge cover C that are rolled up on both sides with the cut L3 as a boundary constitute a pair of lid portions Ct, and the other portions constitute a cover main body Cm. Moreover, the connecting tool between both lid parts Ct' is composed of a single wire fastener F3 that connects the cut L3 in a separable manner.

In the event of a fire occurring in the garbage disposal box 20, etc., the wire fastener F3 is opened to separate the pair of lids Ct, and then a portion of each lid Ct' is picked up and turned upward, for example. As shown in FIG. 9(b), since both lids Ct can be opened to widen the hole Cmh, the tip 50 of the fire hose can be directed toward the gap S through the hole Cmh, as in the first and second embodiments. It can be inserted and extinguishing agent can be quickly injected into the fire area.

The other configurations of the third embodiment are the same as those of the first and second embodiments. Therefore, each component of the third embodiment is given the same reference numeral as the corresponding component of the first and second embodiments, and further structural explanation will be omitted.

In addition, in the third embodiment, only the hinge cover C is illustrated as an example in FIG. 9, but the structure for attaching the hinge cover C to the garbage collection vehicle V is the same as in the first and second embodiments.

Thus, the third embodiment can achieve basically the same effects as the second embodiment.

In particular, the cut L3 in the third embodiment extends from the outer end (one left and right side end) of the hinge cover C, so that the worker can disconnect or connect the wire fastener F3 from the outer side of the garbage disposal box 20. Not only does it have the advantage of being easy to use, but since it is sufficient to use only one wire fastener F3 as a connecting tool, the workability of assembling the wire fastener F3 to the hinge cover C and the operability of opening and closing the lid portion Ct are excellent. .

Although the embodiments of the present invention have been described above, the present invention is not limited to the above embodiments, and various design changes can be made without departing from the scope of the invention described in the claims. is possible.

For example, in the first and second embodiments, a wire fastener (also referred to as a zipper or a zipper) is used as a connecting device that connects the peripheral edge of the hole Cmh of the hinge cover C and the corresponding peripheral edge of the lid Ct. Although the fasteners F, F1, and F2 are illustrated, the connector according to the first feature of the present invention is not limited to the embodiment, and other fasteners such as snap buttons (point fasteners) or hook-and-loop fasteners may also be used. good.

Further, in the first embodiment, one hole Cmh is provided on one left and right side (i.e., the left side) of the hinge cover C, but a plurality of holes (at least two) are provided at multiple locations on the hinge cover C. Cmh may be provided. In this case, if a hole Cmh that is opened and closed by the lid Ct is provided not only on the left side of the hinge cover C but also on the right side, a worker can open the lid Ct from either the left or right side and perform fire extinguishing work. It is convenient to be able to do so.

Further, in the third embodiment, a fastener F3 made of a wire fastener (also referred to as a zipper or a chuck) is exemplified as a connecting tool that detachably connects a pair of lid parts Ct' that can close the hole Cmh of the hinge cover C. The connecting tool according to the fourth feature of the present invention is not limited to the embodiment, and the cut L3 may be connected using other fasteners, such as snap buttons (point fasteners) or hook and loop fasteners.

The present invention relates to a garbage collection vehicle, in particular, a garbage storage box mounted on the vehicle body, a garbage input box supported vertically swingably via a hinge shaft at the upper rear end of the garbage storage box, and an inside of the garbage input box. A garbage loading device is installed in the garbage loading box to load the garbage into the garbage storage box, and the front end is attached to the upper rear part of the garbage storage box, and the rear end is attached to the upper surface of the garbage input box. The hinge cover relates to a garbage collection vehicle that covers the hinge shaft and the gap between the garbage storage box and the garbage input box from above.

The above-mentioned garbage collection vehicle is conventionally known, as shown in Patent Document 1, for example. In the garbage collection vehicle of Patent Document 1, a hinge cover is provided to protect the hinge shaft and surrounding members (for example, various piping, etc.) exposed in the gap between the garbage storage box and the garbage input box from rainwater, dust, etc. used.

Publication No. 5-42962

In the garbage collection vehicle of Patent Document 1, when a trouble such as a fire occurs inside the garbage storage box or the garbage input box, 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 open all the hinge covers quickly, and if the hinge covers are opened completely, the extinguishing agent that has been put in is likely to scatter around, making firefighting operations more efficient. There is a possibility that it cannot be done.

The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a garbage collection vehicle that can solve the above-mentioned problems of the conventional structure with a simple structure.

In order to achieve the above object, the present invention includes a garbage storage box mounted on a vehicle body, a garbage input box supported vertically swingably via a hinge shaft at the upper rear end of the garbage storage box, a garbage loading device disposed in the garbage input box to load the garbage into the garbage storage box; a hinge cover whose rear end is attached to the top surface of the box; the hinge cover covers the hinge shaft and the gap between the garbage storage box and the garbage input box from above; The cover includes a cover body that partially has a hole, a lid portion that closes the hole, and a connector that connects a peripheral edge of at least a portion of the hole and a corresponding peripheral edge of the lid portion in a separable manner. The first feature is that the lid part can open at least a part of the hole by the disconnection of the connector.

Further, in addition to the first feature, the present invention provides that the connecting tool is constituted by a single wire fastener interposed between the peripheral edge of the hole and the peripheral edge of the lid, and A second feature of the wire fastener is that at least the middle portion thereof is formed in an arc shape in the length direction.

Further, in addition to the first feature, the present invention provides that the hinge cover has a pair of cuts extending in parallel with each other from at least one side edge of the left and right sides of the hinge cover, and The portion sandwiched between the cuts constitutes the lid portion, and the other portion constitutes the cover body, and the connecting tool includes a pair of wire fasteners that releasably connect the pair of cuts. The third feature is that

The present invention also provides a garbage storage box mounted on a vehicle body, a garbage input box supported vertically swingably at the upper rear end of the garbage storage box via a hinge shaft, and a garbage storage box disposed within the garbage input box. a garbage loading device for loading garbage into the garbage storage box; a front end portion is attached to the upper rear portion of the garbage storage box; A garbage collection vehicle is provided with a hinge cover to which the hinge shaft is attached, and the hinge cover covers the gap between the hinge shaft and the garbage storage box and the garbage input box from above, the hinge cover has a hole in a part. a pair of lids that can close the hole, and a connector that connects the two lids in a separable manner, and when the connector is separated, the lid closes to the hole. At least a portion of the hinge cover can be opened, and the hinge cover has a single cut extending inward from at least one side edge of the left and right sides of the hinge cover, and the hinge cover can be rolled up on both sides at the cut. A fourth feature is that the portions of the cover constitute the pair of lid portions, and the other portion constitutes the cover body.

According to a first feature of the present invention, a hinge cover for a garbage collection vehicle includes a cover main body that partially has a hole, a lid portion that closes the hole, and a correspondence between the peripheral edge of at least a portion of the hole and the lid portion. and a connecting tool that connects the peripheral edge of the cover body in a separable manner, and by separating the connecting tool, the lid part can open at least a part of the hole, so that in an emergency, the hole in the cover body can be opened. By separating the connecting portion between the peripheral edge and the corresponding peripheral edge of the lid using a connecting tool, the lid can open at least a portion of the hole. As a result, in an emergency, for example, in the event of a fire occurring inside the garbage storage box or garbage disposal box, instead of opening the hinge cover completely, you can open only the part that is covered by the lid (i.e. the hole part) and then open the hinge cover from there. It becomes possible to quickly inject extinguishing agent into the fire area. Furthermore, by opening only a portion of the hinge cover, it is possible to more effectively suppress the wasteful scattering of extinguishing agent into the surrounding area than when the hinge cover is fully opened, and it is possible to carry out fire extinguishing activities more efficiently.

According to a second feature, the connector comprises a single wire fastener interposed between the peripheral edge of the hole and the peripheral edge of the lid, the wire fastener being Since at least the intermediate portion is formed in an arc shape, only a single wire fastener as a connecting device is required, which simplifies the connecting structure and further reduces costs. Moreover, when opening the lid part, it is sufficient to cut off a single wire fastener, and the opening operation can be performed more quickly.

According to the third feature, the hinge cover has a pair of cuts extending in parallel with each other from at least one side edge of the left and right sides of the hinge cover, and the hinge cover is sandwiched between the pair of cuts of the hinge cover. The portion constitutes the lid portion, and the other portion constitutes the cover body, and the connecting tool is constituted by a pair of wire fasteners that connect the pair of cuts in a separable manner. As a result, even if there is a pair of wire fasteners as connecting devices, they extend from the outside edge of the hinge cover, making it easier to disconnect from the outside of the garbage disposal box, and furthermore, each wire fastener has a routing path. Since this is a relatively short straight path, the workability of assembling the wire fastener to the hinge cover and the operability of opening and closing the lid are excellent.

Also, according to the fourth feature, similar to the effect of the first feature, in an emergency, for example, when a fire occurs in the garbage storage box or garbage disposal box, the hinge cover is not completely opened but is closed by the lid. By opening only a portion (i.e., the hole), it is possible to quickly inject extinguishing agent into the fire area, and by opening only a portion of the hinge cover, the amount of extinguishing agent can be injected quickly compared to when the hinge cover is opened completely. It is possible to effectively suppress wasteful scattering in the surrounding area, and it is possible to carry out fire extinguishing activities efficiently. In particular, the hinge cover has a single cut extending inward from the side edges on at least one of the left and right sides of the hinge cover, and the portion of the hinge cover that can be rolled up on both sides with the cut as a border is a pair of lid parts. In addition, since the other parts constitute the cover body, the cut extends inward from the outer edge of the hinge cover, making it easier to disconnect the connector from the outer side of the garbage disposal box. Alternatively, it is sufficient to connect only one cut with a connecting tool, which improves the workability of assembling the connecting tool to the hinge cover and the operability of opening and closing the lid.

Embodiments of the present invention will be described below based on the accompanying drawings.

First, a garbage collection vehicle V according to a first embodiment will be described with reference to FIGS. 1 to 6. The garbage collection vehicle V includes a garbage storage box 10 mounted on a vehicle body frame 1 as a vehicle body, and is supported so as to be vertically swingable via a pair of left and right hinge shafts 21 at the upper rear end of the garbage storage box 10. This device includes a garbage input box 20 and a garbage loading device 30 which is disposed inside the garbage input box 20 and can load the input garbage into the garbage input box 20 into the garbage storage box 10.

The hinge shaft 21 includes a first hinge bracket 10b fixed to both left and right ends of the upper rear end of the garbage storage box 10, and a second hinge bracket 20b fixed to both left and right ends of the upper front end of the garbage storage box 20, respectively. The first and second hinge brackets 10b and 20b are pivotally supported and connected to each other so as to be able to swing relative to each other, particularly in the axially outer half of the hinge shaft 21. The axial movement of the hinge shaft 21 with respect to the first and second hinge brackets 10b and 20b is restricted by a stopper (for example, a circlip, a locking pin, etc. that is removable from the hinge shaft 21).

The garbage storage box 10 is constructed by integrating a rear end frame 10a formed to frame the outer periphery of the rear end with the rear end of the storage box main body 10m, which has a box shape with an open rear end. The inner surface of the frame 10a forms a rear end opening 10i of the garbage storage box 10. Right and left reinforcing plates 15 that cover these from above are joined (for example, welded) to both the left and right ends of the upper end of the rear end frame 10a, and each of the reinforcing plates 15 and the rear end frame 10a are connected to each other by straddling both of them. The first hinge bracket 10b is fixed (for example, welded) so that the first hinge bracket 10b is bent.

Thus, the reinforcing plate 15 increases the support rigidity of the rear end frame 10a to the hinge shaft 21 (and by extension, the garbage input box 20 and the pushing plate driving cylinder 32, which will be described later).

A pair of left and right tilting cylinders 12 are interposed between the garbage input box 20 and the rear end frame 10a of the garbage storage box 10, and the expansion and contraction of the tilting cylinders 12 forces the garbage input box 20 around the hinge shaft 21. It is possible to swing vertically. By swinging up and down, the garbage input box 20 can be moved between the normal use position (i.e., the traveling position shown in FIGS. 1 and 2) covering the rear end opening 10i of the garbage storage box 10, and from there, the garbage input box 20 can be tilted rearward upward to open the rear end opening 10i. 10i is movable between a wide open ejection position (ie, the illustrated position in FIG. 3).

Incidentally, the tilting cylinder 12 is arranged along the outer surface of the input box body 20m of the garbage input box 20, and is covered with side covers 20c fixed to the upper halves of both left and right sides of the input box body 20m.

When the garbage collection vehicle V that has finished collecting waste arrives at the waste treatment facility or waste collection site, the garbage storage box 10 is opened by, for example, swinging the garbage input box 20 upward to the discharge position. The rear end opening 10i is opened to discharge the waste in the garbage storage box 10 to a waste input location such as a waste treatment facility.

In this case, the waste can be discharged from inside the garbage storage box 10 by dumping the garbage storage box 10 forward and upward using a conventionally well-known dump cylinder (not shown) provided between the garbage storage box 10 and the vehicle body frame F. It is possible. Alternatively, the waste can be discharged from the garbage storage box 10 by operating a conventionally known forced discharge device (not shown) installed inside the garbage storage box 10.

Although not shown, the rear surface of the garbage input box 20 is provided with an input port into which waste is to be input into the garbage input box 20, and a door that can open and close the input port as desired. Incidentally, the structures and functions of these input ports and doors are conventionally well known.

Further, the garbage loading device 30 includes a push plate 31 which is housed in the upper part of the garbage input box 20 and whose intermediate portion is pivoted 31p on the left and right side walls of the input box main body 20m of the garbage input box 20, so that it can swing back and forth. A cylinder 32 that swings and drives the push plate 31, a rotary plate 33 located below the push plate 31 and rotatably supported by a shaft 33p on the left and right side walls of the input box main body 20m; It also includes a rotary drive device (not shown) disposed on one left and right side of the input box main body 20m.

As is clear from FIG. 6, the base end of the cylinder 32 is arranged adjacent to the inner side of the second hinge bracket 20b, and is rotatable to the axially inner half of the hinge shaft 21. mated and supported. Further, the distal end of the cylinder 32 is rotatably supported and connected to the upper end of the pushing plate 31.

Then, the garbage thrown into the garbage input box 20 is scraped up by the rotary plate 33 and further pushed into the garbage storage box 10 by the pushing plate 31. This dust scraping and pushing action is well known in the art.

Note that the garbage loading device 30 is not limited to the embodiment. For example, there is a lift plate that is supported on the left and right side walls of the 20 m body of the input box so that it can slide up and down in a forward-leaning position, a cylinder that drives the lift plate to move up and down, and a pusher that is pivotally supported at the bottom of the lift plate so that it can swing back and forth. This type is equipped with a plate and a cylinder for swinging the pushing plate, and combines the lifting and lowering of the lift plate with the back and forth swinging of the pushing plate to compress the input garbage and push it into the garbage storage box 10. Garbage loading device (for example, JP 2010-241553

(see Japanese Patent Publication) may be implemented instead of the garbage loading device 30 of the embodiment.

By the way, the hinge cover C is formed into a roughly rectangular sheet shape made of a flexible and waterproof material (for example, cloth material, rubber material, synthetic resin material, etc.), and the front end Cf of this is formed on the upper surface of the garbage storage box 10. The rear end portion Cr is attached to the front portion of the upper surface of the garbage input box 20. The hinge cover C is for covering from above a horizontally long and open-topped gap S formed between the upper rear end of the garbage storage box 10 and the upper front end of the garbage input box 20.

In the gap S, a plurality of hydraulic piping groups 38 extend from the ceiling of the garbage storage box 10 toward the hydraulic equipment in the garbage input box 20 (i.e., the above-mentioned tilting cylinder 12, the cylinder 32 of the garbage loading device 30, etc.). Also, the aforementioned hinge shaft 21 is exposed. The hinge cover C protects the hinge shaft 21 and the hydraulic piping group 38 from rainwater, dust, sunlight, etc. by covering the gap S from above. In FIG. 6, in order to clearly show the gap S, a part of the right side of the hinge cover C is cut away to show the equipment on the back side of the hinge cover C, but the front side of the actual hinge cover C is shown. - The rear edge and the right edge are simply indicated by two-dot chain lines.

In order to attach this hinge cover C, for example, the thick front end Cf of the hinge cover C is connected to the reinforcing plate 15 of the garbage storage box 10 and the rear end frame 10a by sandwiching the strip-shaped washer 26 between the lower surfaces of the thick front end Cf of the hinge cover C. It can be attached and detached using multiple sets of bolts 18 and weld nuts 19 (the weld nuts 19 are fixed to the upper and lower surfaces of the rear end frame 10a), which are overlapped with each other and pass through the overlapped portions Cf, 26, 15, and 10a at intervals. is combined with On the other hand, the thick rear end portion Cr of the hinge cover C has its lower surface overlapped with the upper surface of the upper wall portion 20a of the garbage input box 20 with the strip washer 27 in between, and the overlapping portion Cr, 27, They are removably connected by a plurality of sets of bolts 28 and weld nuts 29 (the weld nuts 29 are fixed to the lower surface of the upper wall portion 20a) passing through the upper wall portion 20a at intervals.

Note that the front end Cf and rear end Cr of the hinge cover C are connected to the garbage storage box 10 and the rear end Cr using a removable coupling means other than the bolts 18 and 28 and the weld nuts 19 and 29 (for example, a snap button, an elastic clip, etc.). They may be coupled to the garbage input box 20, respectively.

By the way, as is clear from FIG. 6, the hinge cover C has a cover main body Cm having a hole Cmh in a part, a lid part Ct that closes the hole Cmh, and a correspondence between the peripheral edge of at least a part of the hole Cmh and the lid part Ct. It has a single wire fastener F as a connecting tool that connects the peripheral edge of the wire in a separable manner.

To explain more specifically, the hinge cover C has a single U-shaped cut L on one left and right side of the hinge cover C (in the embodiment, the left side), and the hinge cover C has a U-shaped cut L that is surrounded by the cut L. The U-shaped tongue portion constitutes the lid portion Ct, and the other portions (that is, other than the lid portion Ct) constitute the cover main body Cm. That is, the cut L corresponds to the peripheral edge of the hole Cmh and the corresponding peripheral edge of the lid part Ct.

In this embodiment, a single wire fastener F is used as a connecting tool that connects the cut L (that is, the peripheral edge of the hole Cmh and the corresponding peripheral edge of the lid part Ct) so that they can be separated at any time. By separating the wire fastener F, the lid Ct can open at least a portion of the hole Cmh.

The wire fastener F includes a first tape having a large number of first fastener teeth 41 in the longitudinal direction and fixed along the peripheral edge of the hole Cmh, and a large number of second fastener teeth 42 in the longitudinal direction to attach the lid. A second tape fixed along the peripheral edge of the portion Ct, and a slider 40 that can open and close between the first and second fastener teeth 41 and 42 by sliding across them so as to straddle them. The opening and closing functions thereof are well known in the art. Note that since the first and second tapes are conventionally well known, illustration thereof is omitted in FIG.

Moreover, the wire fastener F of the first embodiment is formed such that the front half Fa extends in a convex semicircular arc shape toward the front, and the rear half Fb extends linearly rearward from the rear end (both ends) of the semicircular arc shape. However, in the present invention, at least the intermediate portion may be formed in an arc shape, and the direction of the wire fastener F (cut L) is not limited to that in the first embodiment. For example, it is also possible to implement a modified example in which the direction of the wire fastener F (cut L) of the first embodiment is set to be rotated by a predetermined angle (for example, 60 degrees, 90 degrees, 180 degrees, 270 degrees, etc.). be.

Furthermore, a tensioner is provided on the upper part of the garbage input box 20 to apply a predetermined tension to the hinge cover C so as not to loosen the hinge cover C when the garbage input box 20 is in the normal use position (FIGS. 1 and 4). Both ends of 25 are fixed. The intermediate portion of the tensioner 25 extends in the left-right direction of the garbage input box 20, and has a tension applying portion 25a that comes into contact with the hinge cover C at a position higher than the upper surface of the garbage input box 20.

In the illustrated example of FIG. 4, the tension applying portion 25a of the tensioner 25 is projected sideways forward from the support frame 24 protruding from the upper surface of the garbage disposal box 20, but the modification illustrated in FIG. As in the example, the tension applying portion 25a of the tensioner 25 may be made to protrude upward from the upper surface of the garbage input box 20.

Next, the operation of the first embodiment will be explained. In the garbage collection vehicle V, a horizontally long and open-top gap S is formed between the rear upper end of the garbage storage box 10 and the front upper end of the garbage input box 20, but the gap S is normally closed upward by a hinge cover C. covered from. Therefore, the hinge shaft 21 and the hydraulic piping group 38 exposed in the gap S are protected by the hinge cover C from rainwater, sunlight, and the like. In addition, since the hinge cover C has flexibility, when the garbage input box 20 is tilted rearward and upward in order to discharge the garbage stored in the garbage storage box 10, the hinge cover C is It can be bent and deformed easily.

By the way, during the garbage collection work by the garbage collection vehicle V, there is a possibility that a fire may occur inside the garbage storage box 10 or the garbage input box 20 due to ignition of the input garbage. In this case, in the past, after removing the front end Cf or rear end Cr of the hinge cover C and opening the hinge cover C completely, the space between the rear upper end of the garbage storage box 10 and the front upper end of the garbage input box 20 was removed. The tip of the fire hose is directed toward the gap S between the holes, and the fire extinguishing agent is injected from the tip of the hose. If C is fully opened, there is a problem in that the added extinguishing agent tends to scatter excessively into the surrounding area.

On the other hand, the hinge cover C of the embodiment includes a cover main body Cm having a hole Cmh in a part, a lid portion Ct that closes the hole Cmh, and a peripheral edge of at least a portion of the hole Cmh and a corresponding peripheral edge of the lid portion Ct. The cover Ct has a wire fastener F as a connector that connects the hole Cmh in a separable manner, and by separating the wire fastener F, the lid Ct can quickly and easily open at least a portion of the hole Cmh.

In this way, when a fire occurs in the garbage storage box 10 or the garbage input box 20, the hinge cover C is not opened completely, but only the part covered by the lid part Ct (that is, the part of the hole Cmh) is opened. Since the tip of the fire hose (in FIG. 6, only the cross section of the hose tip is simply indicated by reference numeral 50) can be inserted through the hole Cmh toward the gap S, extinguishing agent can be quickly injected into the fire area. becomes. Furthermore, by opening only a portion of the hinge cover C, it is possible to more effectively suppress the extinguishing agent from being wasted and scattered around than when the hinge cover C is fully opened.

In particular, the connector of the first embodiment is composed of a single wire fastener F interposed between the peripheral edge of the hole Cmh and the peripheral edge of the lid part Ct, and the wire fastener F has a length of At least the intermediate portion is formed in an arc shape in the direction. As a result, it is sufficient to prepare only one wire fastener F for connecting the peripheral edge of the hole Cmh and the corresponding peripheral edge of the lid part Ct, which simplifies the connection structure and further reduces costs. It will be done. Moreover, when opening the lid part Ct, it is sufficient to cut off a single wire fastener F, and the opening operation can be performed more quickly.

By the way, FIG. 7 shows a second embodiment. The hinge cover C of the second embodiment has a pair of cuts L1 and L2 extending parallel to each other from at least one of the left and right side edges (the left edge in the embodiment). The portion of the hinge cover C sandwiched between the pair of cuts L1 and L2 constitutes the lid portion Ct, and the other portion constitutes the cover body Cm. A pair of wire fasteners F1 and F2 extending parallel to each other is used as a pair of connectors that releasably connect the pair of cuts L1 and L2, respectively.

Although not shown, instead of/in addition to the above structure of the second embodiment, the hinge cover C is provided with a pair of cuts L1 and L2 extending in parallel from the right edge of the hinge cover C. The cuts L1 and L2 may be separably connected by a pair of wire fasteners F1 and F2, respectively.

The other configurations of the second embodiment are the same as those of the first embodiment. Therefore, each component of the second embodiment is given the same reference numeral as the corresponding component of the first embodiment, and further structural explanation will be omitted.

Thus, the second embodiment can achieve basically the same effects as the first embodiment.

In particular, the wire fasteners F1 and F2 of the second embodiment, even if there is a pair thereof, extend from the outer edge (one left and right side edge) of the hinge cover C, so that the worker can perform the separation operation from the outer side of the garbage disposal box 20. This has the advantage of making connection work easier. In addition, the routing path of each of the wire fasteners F1 and F2 is a relatively short straight path, and the sliders 40 of both wire fasteners F1 and F2 can be slid in the same direction at the same time to perform separation or connection work. It becomes possible. Therefore, the ease of assembling the wire fasteners F1 and F2 to the hinge cover C and the operability of opening and closing the lid portion Ct are good.

Further, FIG. 9 shows the hinge cover C of the third embodiment in an independent state, in particular, (a) shows the state with the wire fastener F3 closed, and (b) shows the lid part with the wire fastener F3 opened. This shows the state in which Ct is open.

Thus, the hinge cover C of the third embodiment has a cover main body Cm having a hole Cmh in a part, a pair of lid parts Ct' that can close the hole Cmh, and both lid parts Ct' can be separated. The cover Ct' can open at least a portion of the hole Cmh by disconnecting the connector F3.

Moreover, the hinge cover C of the third embodiment has a single cut L3 extending linearly inward from at least one side edge of the left and right sides (the left edge in the third embodiment). The substantially triangular portions of the hinge cover C that are rolled up on both sides with the cut L3 as a boundary constitute a pair of lid portions Ct, and the other portions constitute a cover main body Cm. Moreover, the connecting tool between both lid parts Ct' is composed of a single wire fastener F3 that connects the cut L3 in a separable manner.

In the event of a fire occurring in the garbage disposal box 20, etc., the wire fastener F3 is opened to separate the pair of lids Ct, and then a portion of each lid Ct' is picked up and turned upward, for example. As shown in FIG. 9(b), since both lids Ct can be opened to widen the hole Cmh, the tip 50 of the fire hose can be directed toward the gap S through the hole Cmh, as in the first and second embodiments. It can be inserted and extinguishing agent can be quickly injected into the fire area.

The other configurations of the third embodiment are the same as those of the first and second embodiments. Therefore, each component of the third embodiment is given the same reference numeral as the corresponding component of the first and second embodiments, and further structural explanation will be omitted.

In addition, in the third embodiment, only the hinge cover C is illustrated as an example in FIG. 9, but the structure for attaching the hinge cover C to the garbage collection vehicle V is the same as in the first and second embodiments.

Thus, the third embodiment can achieve basically the same effects as the second embodiment.

In particular, the cut L3 in the third embodiment extends from the outer end (one left and right side end) of the hinge cover C, so that the worker can disconnect or connect the wire fastener F3 from the outer side of the garbage disposal box 20. Not only does it have the advantage of being easy to use, but since it is sufficient to use only one wire fastener F3 as a connecting tool, the workability of assembling the wire fastener F3 to the hinge cover C and the operability of opening and closing the lid portion Ct are excellent. .

Although the embodiments of the present invention have been described above, the present invention is not limited to the above embodiments, and various design changes can be made without departing from the scope of the invention described in the claims. is possible.

For example, in the first and second embodiments, a wire fastener (also referred to as a zipper or a zipper) is used as a connecting device that connects the peripheral edge of the hole Cmh of the hinge cover C and the corresponding peripheral edge of the lid Ct. Although the fasteners F, F1, and F2 are illustrated, the connector according to the first feature of the present invention is not limited to the embodiment, and other fasteners such as snap buttons (point fasteners) or hook-and-loop fasteners may also be used. good.

Further, in the first embodiment, one hole Cmh is provided on one left and right side (i.e., the left side) of the hinge cover C, but a plurality of holes (at least two) are provided at multiple locations on the hinge cover C. Cmh may be provided. In this case, if a hole Cmh that is opened and closed by the lid Ct is provided not only on the left side of the hinge cover C but also on the right side, a worker can open the lid Ct from either the left or right side and perform fire extinguishing work. It is convenient to be able to do so.

Further, in the third embodiment, a fastener F3 made of a wire fastener (also referred to as a zipper or a chuck) is exemplified as a connecting tool that detachably connects a pair of lid parts Ct' that can close the hole Cmh of the hinge cover C. The connecting tool according to the fourth feature of the present invention is not limited to the embodiment, and the cut L3 may be connected using other fasteners, such as snap buttons (point fasteners) or hook and loop fasteners.
