In addition, the ordinal numbers used in the following specification and drawings may differ from the ordinal numbers described in the claims.
[0012] Hereinafter, one embodiment of a refuse collection vehicle will be described with reference to Figures 1 to 3. Note that the following embodiment is provided as an example to aid in understanding the configuration of the refuse collection vehicle, and is not intended to limit the configuration of the refuse collection vehicle.
[0013] As shown in Fig. 1, a refuse collection vehicle 1 may include a vehicle body 2, a refuse collection box 3 mounted on the vehicle body 2, and a refuse input box 4 connected to the rear of the refuse collection box 3. In the following description and each figure, the first direction D1 is also referred to as the front-rear direction D1, the second direction D2 is also referred to as the left-right direction D2, and the third direction D3 is also referred to as the up-down direction D3. That is, each of the directions D1 to D3 is a direction seen from a person (driver) sitting in the driver's seat of the refuse collection vehicle 1.
[0014] In the front-to-back direction D1, the direction of the arrow in the figure is the front direction, and the opposite direction to the arrow direction in the figure is the rear direction. In the left-to-right direction D2, the direction of the arrow in the figure is the left direction, and the opposite direction to the arrow direction in the figure is the right direction. In the up-down direction D3, the direction of the arrow in the figure is the up direction, and the opposite direction to the arrow direction in the figure is the down direction.
[0015] The vehicle body 2 may include, for example, a driver's cab 2a disposed at the front, a vehicle body frame 2b disposed at the rear, and a plurality of wheels 2c, as in this embodiment.
[0016] The dust collection box 3 may be, for example, connected to the dust input box 4, and configured so that dust input into the dust input box 4 is stored therein.
[0017] The trash bin 4 may have an inlet 4a through which trash is inserted from the rear end side, as shown in FIG. 2. The trash bin 4 may have an opening / closing cover 4b1 and a table 4b2, as shown in FIG. 2 and FIG. 3, and the opening / closing cover 4b1 slides in the vertical direction D3, and the table 4b2 opens and closes the inlet 4a. The lower end 4c of the inlet 4a is the lower end 4c of the inlet 4a when the table 4b2 is open, as shown in FIG. 2. The trash bin 4 may not have the table 4b2. In this case, the lower end position of the slide cover 4b1 when the inlet 4a is closed, that is, when the slide cover 4b1 is at the lowest position within the movable range, corresponds to the lower end 4c of the inlet 4a.
[0018] The openable cover 4b1 may be configured to be housed inside the trash dump box 4 when it is slid upward to open the drop opening 4a, as shown in FIG.
[0019] In addition, the garbage dump box 4 may be equipped with a reverse warning alarm 10 that emits a warning sound rearward when the garbage collection vehicle 1 reverses, and a stiffener 11 for reinforcing the garbage dump box 4, as in this embodiment.
[0020] 2, the reverse horn 10 may be fixed to the stiffener 11 above the input port 4a, more specifically, above the area between the left end 4d and the right end 4e in the left-right direction D2 of the input port 4a, so as to emit a warning sound toward the rear of the refuse collection vehicle 1. Also, the reverse horn 10 may be fixed, for example, above the stiffener 11, so as to emit a warning sound toward the rear of the refuse collection vehicle 1.
[0021] The back-up horn 10 may be disposed on the wall surface of the stiffener 11 without being covered by other members, as in this embodiment.
[0022] The stiffener 11 may be, for example, a metal member that extends in one direction and has a rectangular cross-sectional shape when cut along a plane perpendicular to the extending direction, or may be a metal member that has an H-shaped cross-sectional shape. The stiffener 11 is disposed above the insertion port 4a so as to extend in the left-right direction D2, as shown in Fig. 2, for example, but the position and orientation of the stiffener 11 are not limited thereto.
[0023] Although not particularly limited, the wiring of the reverse alarm 10 may be wired, for example, along the outer wall surfaces of the trash collection box 3 and the trash drop box 4, or may be wired inside the trash collection box 3 and the trash drop box 4. Also, for example, the wiring of the reverse alarm 10 may be wired between the trash drop box 4 and the stiffener 11, or inside the stiffener 11, or may be wired along the outer surface of the stiffener 11.
[0024] As a result, the reverse horn 10 of the refuse collection vehicle 1 is disposed at a position higher than the area into which the dust and liquid scattered around the input port 4a falls. Therefore, for example, it is possible to prevent the dust and the like scattered around the input port 4a from adhering to the reverse horn 10.
[0025] In addition, the garbage collection vehicle 1 has the reverse warning horn 10 disposed above the input port 4a, that is, at a position higher than the position where garbage is input. Therefore, for example, when an operator inputs garbage into the input port 4a, it is possible to prevent the garbage from hitting the reverse warning horn 10.
[0026] As described above, the garbage collection vehicle 1, as in this embodiment, A trash input box 4 having an input port 4a through which trash is input from the rear end side; and a rearward warning sound device 10 that is disposed above the lower end 4c of the insertion port 4a and emits a warning sound toward the rear. This configuration is preferred.
[0027] According to this configuration, the reverse warning horn 10 is disposed at a position higher than the area into which the dust and liquid scattered around the input port 4a falls. Therefore, it is possible to prevent the dust and the like scattered around the input port 4a from adhering to the reverse warning horn 10.
[0028] In addition, the garbage collection vehicle 1, as in this embodiment, The rearview horn 10 is disposed above the insertion port 4a. This configuration is preferred.
[0029] According to this configuration, the reverse warning horn 10 is disposed above the input port 4a, that is, at a position higher than the position where the trash is input. Therefore, when an operator inputs trash into the input port 4a, the trash can be prevented from hitting the reverse warning horn 10.
[0030] The refuse collection vehicle 1 is not limited to the configuration of the above-mentioned embodiment, and is not limited to the above-mentioned action and effect. Of course, the refuse collection vehicle 1 can be modified in various ways without departing from the gist of the present invention. For example, it is of course possible to arbitrarily select one or more of the configurations and methods of the various modified examples described below and adopt them in the configurations and methods of the above-mentioned embodiment.
[0031] (A) In the refuse collection vehicle 1 according to the above embodiment, the reverse warning alarm 10 is disposed above the input port 4a of the refuse collection box 3. However, the refuse collection vehicle 1 is not limited to such a configuration.
[0032] For example, as shown in Figs. 4 and 5, the refuse collection vehicle 1 may be configured such that the reverse alarm 10 is disposed above the lower end 4c of the input port 4a and spaced apart from the input port 4a in the left-right direction D2.
[0033] (A-1) First, the garbage collection vehicle 1 shown in FIG. 4 will be described below.
[0034] 4, the refuse collection vehicle 1 may include, for example, a support member 10a fixed so as to extend in the left-right direction D2 from the refuse bin 4. The reverse warning horn 10 may be fixed to the rear side of the support member 10a and disposed away from the bin opening 4a in the left-right direction D2 when viewed from behind.
[0035] The method of fixing the backup horn 10 to the support member 10a is not particularly limited, and may be, for example, by joining (e.g., welding, adhesive, etc.), or may be by using fastening means (e.g., bolts and nuts, etc.).
[0036] Also, the support member 10a may be fixed so as to extend in the left-right direction D2 from the trash collection box 3. The fixing of the support member 10a to the trash collection box 3 or the fixing of the support member 10a to the trash input box 4 is not particularly limited, and may be fixed by joining (for example, welding, adhesion, etc.) or may be fixed using fastening means (for example, bolts and nuts, etc.).
[0037] As a result, the reverse warning horn 10 is disposed above the lower end 4c of the input port 4a of the refuse collection vehicle 1. Therefore, for example, it is possible to prevent dust or the like scattered near the input port 4a from adhering to the reverse warning horn 10.
[0038] Further, in the sewage collection vehicle 1, the reverse warning horn 10 is disposed at a position spaced apart in the left-right direction D2 from the input port 4a when viewed from the rear.
[0039] As shown in FIG. 4, the garbage collection vehicle 1 may be configured so that, for example, the opening / closing cover 4b1 moves outside the garbage dump box 4 when it is slid upward to open the dump port 4a.
[0040] In this case, as shown in Fig. 4, even when the refuse collection vehicle 1 has the inlet 4a open, the warning sound emitted from the reverse warning sound device 10 is not blocked by the openable cover 4b1. Therefore, regardless of the state of the openable cover 4b1, people behind the refuse collection vehicle 1 can more reliably hear the warning sound emitted from the reverse warning sound device 10.
[0041] As a result, the garbage collection vehicle 1 is as shown in Figure 4. A trash input box 4 having an input port 4a through which trash is input from the rear end side; and a rearward warning sounder 10 that is disposed above the lower end 4c of the insertion port 4a and that emits a warning sound toward the rear. The rearward warning horn 10 is disposed at a distance from the insertion port 4a in the left and right directions when viewed from the rear. This configuration is preferred.
[0042] According to this configuration, the reverse alarm 10 is disposed above the lower end 4c of the input port 4a. Even if the openable cover 4b1 is configured to move outside the garbage input box 4 when it is slid upward to open the input port 4a, the alarm sound emitted from the reverse alarm 10 is not blocked by the openable cover 4b1. This makes it possible to prevent dust and the like scattered near the input port 4a from adhering to the reverse alarm 10. Furthermore, regardless of the state of the openable cover 4b1, a person present behind the garbage collection vehicle 1 can more reliably hear the alarm sound emitted from the reverse alarm 10. Furthermore, according to this configuration, the reverse alarm 10 can be attached to a predetermined position regardless of the shape and structure of the openable cover 4b1. Therefore, it is not necessary to consider the position to attach the reverse alarm 10 each time depending on the shape and structure of the openable cover 4b1, and the work efficiency is improved when manufacturing the garbage collection vehicle 1.
[0043] (A-2) Next, the refuse collection vehicle 1 shown in FIG. 5 will be described below.
[0044] 5, the refuse collection vehicle 1 may not be provided with the support member 10a if, for example, there is an area for fixing the reverse horn 10 at a position spaced apart from the input opening 4a in the left-right direction D2 when viewed from the rear. The reverse horn 10 may be configured to be disposed above the input opening 4a and spaced apart from the input opening 4a in the left-right direction D2 when viewed from the rear.
[0045] As a result, the reverse warning horn 10 is disposed above the lower end 4c of the input port 4a of the refuse collection vehicle 1. Therefore, for example, it is possible to prevent dust or the like scattered near the input port 4a from adhering to the reverse warning horn 10.
[0046] In addition, the garbage collection vehicle 1 has the reverse warning horn 10 disposed above the input port 4a. Therefore, for example, when an operator inputs garbage into the input port 4a, the garbage can be prevented from hitting the reverse warning horn 10.
[0047] In addition, the sewage collection vehicle 1 has the reverse horn 10 disposed at a position away from the input port 4a in the left-right direction D2 when viewed from the rear. Therefore, even when the input port 4a of the sewage collection vehicle 1 is open, the warning sound emitted from the reverse horn 10 is not blocked by the opening / closing cover 4b1. Therefore, regardless of the state of the opening / closing cover 4b1, people present behind the sewage collection vehicle 1 can more reliably hear the warning sound emitted from the reverse horn 10.
[0048] As a result, the garbage collection vehicle 1 is as shown in Figure 5. A trash input box 4 having an input port 4a through which trash is input from the rear end side; and a rearward warning sounder 10 that is disposed above the lower end 4c of the insertion port 4a and that emits a warning sound toward the rear. The reverse warning horn 10 is disposed above the input port 4a and separated from the input port 4a in the left-right direction when viewed from the rear. This configuration is preferred.
[0049] According to this configuration, the reverse warning horn 10 is disposed above the input port 4a, that is, at a position higher than the position where the trash is input. Therefore, when an operator inputs trash into the input port 4a, the trash can be prevented from hitting the reverse warning horn 10.
[0050] (B) In the refuse collection vehicle 1 according to the above embodiment, the reverse horn 10 is arranged in an exposed state. However, the refuse collection vehicle 1 is not limited to this configuration. The refuse collection vehicle 1 may be configured, for example, so that the reverse horn 10 is visible from the rear inside a recess provided in the refuse bin 4. The shape, size, depth, etc. of the recess in which the reverse horn 10 is provided may be arbitrary as long as the reverse horn 10 is visible from the rear of the refuse collection vehicle 1.
[0051] Also, the sewage collection vehicle 1 may be arranged in a position where no components are arranged behind it so that the reverse horn 10 is visible from the rear. Here, being visible from the rear means that, assuming an angle range of 0° in the rear direction, +90° in the left direction, and -90° in the right direction with the rear end of the sewage collection vehicle 1 as a reference, at least a part of the reverse horn 10 is arranged so as to be visible when the sewage collection vehicle 1 is viewed from any direction within the range of -90° to +90°. It is preferable that the reverse horn 10 is arranged so that at least a part of it is visible when viewed from any position behind the rear end of the sewage collection vehicle 1 and within the range of the width of the sewage collection vehicle 1 in the left-right direction D2. Furthermore, it is preferable that the part of the reverse horn 10 that is visible from any of the above-mentioned positions is at least a part of the part that emits the horn.
[0052] This ensures that the warning sound emitted by the reverse warning device 10 when the refuse collection vehicle 1 reverses is not blocked. Therefore, for example, a person behind the refuse collection vehicle 1 can more reliably hear the warning sound emitted from the reverse warning device 10.
[0053] Furthermore, for example, if the reverse horn 10 is arranged inside a recess provided in the garbage dump box 4, it is possible to further prevent dust and the like from adhering to the reverse horn 10 and to prevent the reverse horn 10 from being damaged.
[0054] As described above, the garbage collection vehicle 1, as in this embodiment, A trash input box 4 having an input port 4a through which trash is input from the rear end side; and a rearward warning sounder 10 that is disposed above the lower end 4c of the insertion port 4a and that emits a warning sound toward the rear. The rearview horn 10 is arranged so as to be visible from the rear. This configuration is preferred.
[0055] According to this configuration, the sound emitted backward from the reverse warning device 10 is not blocked by other members. Therefore, people behind the refuse collection vehicle 1 can more reliably hear the warning sound emitted from the reverse warning device 10.
[0056] (C) In the refuse collection vehicle 1 according to the above embodiment, the reverse horn 10 is disposed in a position shifted to the left from the center in the left-right direction D2 of the refuse collection vehicle 1. However, the refuse collection vehicle 1 is not limited to such a configuration. The reverse horn 10 may be disposed in the center of the refuse collection vehicle 1 or in a position shifted to the right from the center. In other words, the reverse horn 10 may be disposed in any position as long as it is at least above the lower end 4c of the input port 4a.
[0057] (D) In the refuse collection vehicle 1 according to the above embodiment, the reverse warning horn 10 is arranged to emit a sound toward the rear of the refuse collection vehicle 1. However, the refuse collection vehicle 1 is not limited to such a configuration. The reverse warning horn 10 may be arranged to emit a warning toward the left rear or right rear. In addition, the reverse warning horn 10 may be arranged, for example, above the input port 4a so as to emit a warning toward the lower rear.
[0058] (E) In addition, in the refuse collection vehicle 1 according to the above embodiment, the opening and closing cover 4b1 slides in the vertical direction D3, and the table 4b2 opens and closes to open and close the drop opening 4a. However, the refuse collection vehicle 1 is not limited to such a configuration. For example, the opening and closing cover 4b1 may be configured to slide in the left-right direction D2 when opening and closing the drop opening 4a, or may be configured like a flip-up door. Furthermore, the opening and closing cover 4b1 may be configured to be connected to the refuse drop box 4 via an arm so that, for example, an operator grasps the handle and pulls it toward himself, lifting it up in the vertical direction D3 to open the drop opening 4a.
