Description

[Technical Field]

[0001] The present invention relates to a refuse collection vehicle that collects and transports refuse and the like. [Background technology]

[0002] 2. Description of the Related Art Refuse collection trucks that collect general waste from households and food waste from restaurants and the like are widely known. A refuse collection vehicle has a refuse collection device mounted on the vehicle body. The refuse collection device has a refuse storage box for storing refuse, a refuse drop box connected to the refuse storage box and into which the refuse can be dropped, and a loading device provided inside the refuse drop box for loading the dropped refuse into the refuse collection box.

[0003] Here, it may be necessary to bring the loading device to an emergency stop if a worker is about to get caught in the loading device, or if the worker accidentally discovers garbage that should not be loaded, etc. Patent Document 1 discloses a garbage collection vehicle equipped with an emergency stop device that brings the loading device to an emergency stop.

[0004] The emergency stop device disclosed in Patent Document 1 is equipped with an operating bar, and is activated by moving the lower end of the operating bar either forward or backward. The operating bar also has an L-shaped plate-like portion at its lower end that bends and extends forward, and an operator swings this L-shaped portion forward or backward to move the lower end of the operating bar forward or backward.

[0005] [Patent Document 1] Japanese Patent Publication No. 2023-070538 Summary of the Invention [Problem to be solved by the invention]

[0006] Here, because the emergency stop device is used in emergencies that are different from normal, in actual use, there are cases where a panicked worker kicks or hits the operation bar hard, activating the emergency stop device. In other words, there is room for improvement in conventional garbage collection trucks in terms of improving the strength of the operating part of the emergency stop device to prepare for rough operation by workers.

[0007] Therefore, the inventors considered providing a reinforcing plate to improve the strength of the operation bar. However, when the operation bar is structured in this way, the reinforcing plate gets in the way when a worker tries to grip the operation bar with their hands, making it difficult to grasp the operation bar properly. As described above, the emergency stop device is used in an emergency, so the worker does not have time to search for a part that is easy to grip with their hands, and it needs to be able to operate the device with the part that they can quickly grab and activate it immediately. In other words, conventional emergency stop devices had room for improvement in terms of improving operability by increasing the strength of the operating member operated by the worker, while also making it easier for the worker to operate the operating member in various cases where they grasp it at various locations.

[0008] SUMMARY OF THE INVENTION It is therefore an object of the present invention to provide a garbage collection vehicle having an emergency stop device equipped with an operating member that is stronger and easier to operate. [Means for solving the problem]

[0009] One aspect of the present invention for solving the above-mentioned problems is a garbage collection vehicle comprising a vehicle body and a garbage collection device mounted on the vehicle body, the garbage collection device having a garbage collection box for storing garbage, a garbage drop box into which garbage can be thrown, and a loading device, the loading device performs an operation of sending garbage thrown into the garbage drop box into the garbage collection box, and has an emergency stop device for emergency stopping the loading device, the emergency stop device has an operating member, and the loading device is brought to an emergency stop by operating to move at least a part of the operating member, the operating member has a plate portion, a handle portion, and a reinforcing portion, the plate portion is rotatable and when a state before the operation of the operating member is defined as a first state, the operating member has a portion that extends in the vertical direction in the first state, the handle portion is a portion that protrudes from a lower portion of the plate portion in the first state, the reinforcing portion is arranged on the tip side of the plate portion in the protruding direction of the handle portion and is continuous with the plate portion, and extends in a direction that includes a vertical component so that its lower end portion is continuous with an upper portion of the handle portion, and the portion of the reinforcing portion adjacent to the upper side of the handle portion has a tip end in the protruding direction that is located closer to the base end in the protruding direction than the tip end of the handle portion.

[0010] According to this aspect, the reinforcing portion reinforces the strength of the operating member, and the reinforcing portion does not get in the way when grasping the handle portion to operate it, making it easier to operate the operating member.

[0011] In a preferred aspect, the emergency stop device can be pulled to move the lower part of the operating member in a direction that includes a directional component toward the rear of the vehicle body, and the loading device is brought to an emergency stop by at least performing the pulling operation, and the handle portion protrudes in a direction that includes a directional component toward the front of the vehicle body in the first state, and the reinforcing portion is located further forward of the vehicle body than the plate portion in the first state.

[0012] According to this aspect, when grabbing and pulling a position that is difficult to see, it is possible to make the operation easier in each of the various places that are grabbed, thereby improving operability.

[0013] In a preferred aspect, the reinforcing portion includes a lower component including a portion adjacent to the upper side of the handle portion, and an upper component located above the lower component, and the lower component has a portion whose tip side in the protruding direction is located closer to the base end in the protruding direction than the tip side portion in the protruding direction of the upper component.

[0014] According to this aspect, it is possible to further increase the strength of the periphery of the upper portion of the reinforcing portion, and it is possible to further improve the strength of the operating member.

[0015] In a more preferred aspect, the reinforcing portion has a portion whose tip end in the protruding direction extends so as to be positioned closer to the base end in the protruding direction as it extends from above to below.

[0016] According to this aspect, the strength of the operating member can be further improved.

[0017] In a preferred aspect, the operating member has side wall portions, the reinforcing portion is arranged between two of the side wall portions, the side wall portions extend in a direction that includes an up-down component, and at least a portion of the reinforcing portion is located closer to the base end in the protruding direction than the tip end portion of the side wall portions in the protruding direction.

[0018] According to this aspect, the side wall portion allows the reinforcing portion to be positioned in a position that is difficult to see from the outside, improving the appearance of the garbage collection vehicle (operating member). In addition, the strength of the operating member can be improved compared to a structure without a side wall portion.

[0019] In a preferred aspect, the maximum thickness of the portion of the reinforcing part that is located closer to the tip in the protruding direction than the portion adjacent to the upper side of the handle part is thicker than at least a portion of the other parts of the handle part or at least a portion of the plate part.

[0020] According to this aspect, when a worker grasps the handle to operate it, the part that the fingers often come into contact with is thicker, and the worker can grasp the handle with the fingers and palm of the hand at a comfortable distance, making it easier to grasp and operate the handle. [Effects of the Invention]

[0021] The present invention can provide a garbage collection vehicle having an emergency stop device equipped with an operating member that is stronger and easier to operate. [Brief explanation of the drawings]

[Figure 15] FIG. 10 is a side view showing an operating member main body according to an embodiment different from the above-described embodiments. DETAILED DESCRIPTION OF THE INVENTION

[0023] The first embodiment of the present invention will be described in detail below. In the following description, the front-rear and up-down relationships are the same as those of the vehicle body 2, with the driver's cab 2a side being the front side and the garbage collection device 3 (garbage bin 11) side being the rear side. Of the front-rear directions, the direction from the rear to the front will also be referred to as the first direction, and the direction from the front to the rear will also be referred to as the second direction.

[0024] As shown in FIG. 1, a garbage collection vehicle 1 of this embodiment is formed by mounting a garbage collection device 3 on a vehicle body 2.

[0025] The vehicle body 2 has a driver's cab 2a and a vehicle body frame 2b (chassis) extending rearward from the lower part of the driver's cab 2a.

[0026] The garbage collection device 3 has a garbage storage box 10 for storing garbage, a garbage throw-in box 11 connected to the rear side of the garbage storage box 10, and a loading device 12 housed in the garbage throw-in box 11.

[0027] The dust collection box 10 is a box that is open at the rear end side and has a collection space inside that can store dust. The garbage bin 11 has a lid 18 (see FIG. 2), and by opening and closing the lid 18 by an operator, the garbage inlet is switched between an open state and a closed state. In other words, by opening the lid 18, garbage can be thrown into the internal space of the garbage bin 11 from the garbage inlet. The internal space of this garbage bin 11 is a space that is continuous with the storage space of the garbage storage box 10.

[0028] The loading device 12 performs a loading operation of sending the items (garbage) that have been thrown into the internal space of the garbage dump box 11 into the garbage collection box 10. The loading device 12 employed in this embodiment is called a rotary plate type loading device, and has a structure in which a swinging push plate 20 and a rotary plate 21 are combined. The pusher plate 20 is disposed above the rotary plate 21 and swings back and forth. The rotating plate 21 rotates around a horizontal axis 25 .

[0029] The loading operation performed by the loading device 12 involves rotating the rotating plate 21 to scoop up the garbage that has been thrown into the internal space of the garbage dump box 11 to a certain height. Furthermore, as the pushing plate 20 swings, the tip of the pushing plate 20 wipes the surface of the rotating plate 21, pushing the garbage into the storage space within the garbage storage box 10. This sends the garbage in the garbage dump box 11 into the storage space within the garbage storage box 10.

[0030] Here, the garbage collection vehicle 1 of this embodiment is equipped with a control device (not shown) that controls the operation of the hydraulic control system of the loading device 12, and an emergency stop device 30 that is connected to the control device and is used to bring the loading device 12 to an emergency stop at any time. The control device is similar to a well-known device that can output an electrical operation control signal to the hydraulic control system of the loading device 12 based on an operator's operation input to an operation device (not shown, for example, an operation panel or remote control provided at an appropriate location on the vehicle body 2). The hydraulic control system of the loading device 12 is specifically a hydraulic control system that can drive a push cylinder that drives the push plate 20 to swing and a rotary motor that drives the rotary plate 21 to rotate.

[0031] As shown in Figure 3, the emergency stop device 30 has an operating member 35, a shaft member 36, a contact portion forming member 37, a dog member 38, a sensor member 39, an operating body mounting member 40, a shaft support member 41, a first biasing member 42, and a second biasing member 43.

[0032] The emergency stop device 30, which will be described in detail later, can be activated by performing a pulling operation (see FIG. 3(b)) to move the lower end portion of the operating member 35 rearward (in a direction including a second directional component) from the pre-operation state (see FIG. 3(a)), thereby bringing the loading device 12 to an emergency stop. In addition, the emergency stop device 30 can also be activated by performing a pushing operation (see FIG. 3(c)) to move the lower end portion of the operating member 35 forward (in a direction including a first directional component) from the pre-operation state (see FIG. 3(a)). In the following description, the normal state (see FIG. 3(a)) before the operating member 35 is pulled or pushed is referred to as the first state. The state (see FIG. 3(b)) after the operating member 35 is pulled is referred to as the second state, and the state (see FIG. 3(c)) after the operating member 35 is pushed is referred to as the third state. In the following description, unless otherwise specified, the up-down direction, the front-rear direction, and the left-right direction (the width direction of the vehicle body 2) will be described based on the first state.

[0033] As shown in FIG. 4, the operating member 35 is formed by attaching a reflector 51 to an operating member body 50. The operating member body 50 is a characteristic member of this embodiment, and will be described in detail later. The reflector 51 is a plate-like or sheet-like member that has a substantially horizontally elongated rectangular shape when viewed from behind, and functions as a light reflector that reflects surrounding light. Specifically, the reflector 51 of this embodiment is formed by arranging reflective material such as tiny glass beads on a plate-like or sheet-like main body member.

[0034] 4, the operating member 35 of this embodiment has an operating member main body 50 and two reflecting plates 51, and the two reflecting plates 51 are attached to a back plate portion 65 (plate portion, described in detail later) of the operating member main body 50. In detail, the two reflecting plates 51 are arranged side by side in the left-right direction, and are arranged so that each reflecting plate 51 overlaps with the back plate portion 65 in the front-rear direction, and are fixed via temporary fastening elements. The term "temporary fastening element" as used herein refers to a type of fastening element, and is a general term for mechanical components that connect fastened objects so that they can be removed non-destructively, such as screws, bolts, nuts, etc. This also applies to the following explanations.

[0035] As shown in Figure 2, the operating member 35 of this embodiment is provided below the lid portion 18 (the opening of the garbage dump box 11) and is arranged in an extended position in the left-right direction so that its longitudinal direction is the left-right direction (vehicle width direction).

[0036] The shaft member 36 is a rod-shaped member extending in the front-rear direction, as shown in Fig. 3. The shaft member 36 of this embodiment has a screw thread (not shown) formed on the outer peripheral surface of the front portion, allowing a nut or the like to be attached. 3 and 5, the rear end portion of the shaft member 36 is attached to the operating member 35 via a connecting shaft member 55 (see FIG. 5). In detail, the shaft member 36 has a shaft insertion hole (not shown) at the rear end portion through which the connecting shaft member 55 can be inserted, and this shaft insertion hole extends in a direction perpendicular to the longitudinal direction of the shaft member 36 (left-right direction) and penetrates the shaft member 36. 5, a portion of the shaft member 36 is disposed between two reinforcing vertical plate portions 68 (reinforcing portions, described in detail later), and the connecting shaft member 55 extends through the two reinforcing vertical plate portions 68 and the shaft member 36 therebetween. In other words, the connecting shaft member 55 is inserted through connecting shaft insertion holes 91 (see FIG. 6, described in detail later) provided in each of the two reinforcing vertical plate portions 68 and the shaft insertion hole of the shaft member 36. For convenience of drawing, detailed illustrations of attachment members (pins, washers, etc.) used to attach the connecting shaft member 55 are omitted. As a result of the above, the shaft member 36 is attached to the operating member body 50 in a cantilevered manner and is swingable about the axis of the connecting shaft member 55 .

[0037] 3, the abutment portion forming member 37 is attached to a portion of the front side of the shaft member 36. The abutment portion forming member 37 is the portion that abuts against the end of the first biasing member 42, and has a standing plate-like portion that protrudes outward from the outer circumferential surface of the shaft member 36. In this embodiment, this standing plate-like portion has a thickness in the front-to-rear direction and is continuous in an annular shape around the axis of the shaft member 36. In this embodiment, a flanged nut is used as the abutment portion forming member 37.

[0038] Although not shown in detail, the dog member 38 is a thick, disk-shaped member and has a shaft insertion hole that penetrates the dog member 38 in the thickness direction and through which a portion of the shaft member 36 is inserted. The dog member 38 is attached to a longitudinal midpoint of the shaft member 36. That is, with a portion of the shaft member 36 disposed in the shaft insertion hole of the dog member 38, the dog member 38 is fixed to the shaft member 36 by a fixing means such as welding. Therefore, the shaft member 36 extends through a portion of the dog member 38.

[0039] The sensor member 39 is a sensor that detects at least a part of the dog member 38 and can detect without contact whether the detection object has approached a predetermined position or whether the detection object has moved away from the predetermined position, and in this embodiment, a proximity sensor is used. That is, when the emergency stop device 30 of this embodiment transitions from the first state to the second state or the third state by a pulling operation or a pushing operation, at least a portion (the portion to be detected) of the dog member 38 moves from its position in the first state. As the portion to be detected of the dog member 38 moves, the sensor member 39 detects that the portion to be detected of the dog member 38 has moved away from its position in the first state, and the sensor member 39 outputs a signal to the control device (not shown). The control device brings the loading device 12 to an emergency stop when it receives a signal transmitted from the sensor member 39 as one of its conditions.

[0040] 3 and 5, the operating body mounting member 40 is a member having two paired upright plate-like members 40a (see FIG. 5), and is a member that is fixed to the garbage bin 11 directly by welding or the like, or indirectly via another member. As shown in FIG. 5, the garbage collection vehicle 1 of this embodiment has two operating body mounting members 40, and the two operating body mounting members 40 are arranged at the same height and at positions spaced apart in the left-right direction.

[0041] In the refuse collection vehicle 1 of this embodiment, the operating member 35 is attached to the operating body mounting member 40 via a swing shaft member 58. That is, although not shown, the upright plate-shaped member 40a is provided with a shaft insertion hole that penetrates the upright plate-shaped member 40a in the thickness direction and through which the swing shaft member 58 can be inserted. Each of the two operating body mounting members 40 is disposed between two different reinforcing vertical plate portions 68 (reinforcing portions, described in detail below), and the swing shaft member 58 extends through the two reinforcing vertical plate portions 68 and the two operating body mounting members 40 between them. In other words, the swing shaft member 58 is inserted through a swing shaft insertion hole 90 (see FIG. 6, described in detail below) provided in each of the two reinforcing vertical plate portions 68 and the shaft insertion hole of the operating body mounting member 40. As a result, the operating member 35 (operating member main body 50) is attached to the two operating body attachment members 40 so as to be able to swing freely around the axis of the swing shaft member 58 (see FIG. 3). For convenience of drawing, detailed illustrations of attachment members (pins, washers, etc.) used to attach the swing shaft member 58 are omitted.

[0042] Although detailed illustrations of the shaft support member 41 are omitted, as shown in Figure 3, it is a member having a vertical support plate portion 41a that is thick in the front-to-rear direction, and is fixed to the garbage bin 11 directly by welding or the like, or indirectly via other members. The support plate portion 41a has a support member insertion hole 41b that penetrates the support plate portion 41a in the thickness direction, and a part (a midway portion in the length direction) of the shaft member 36 is disposed in the support member insertion hole 41b. Here, the inner diameter of the support member insertion hole 41b is sufficiently larger than the outer diameter of the shaft member 36, and a part of the shaft member 36 is loosely fitted in the support member insertion hole 41b.

[0043] The first biasing member 42 and the second biasing member 43 are both coil springs that, when compressed, exert an elastic restoring force in the direction opposite to the compression direction. The first biasing member 42 and the second biasing member 43 are both fitted onto the shaft member 36. The first biasing member 42 is disposed between the abutment portion forming member 37 and the shaft support member 41, with its front end portion abutting against the rear side surface of the abutment portion forming member 37 and its rear end portion abutting against the front side surface of the shaft support member 41 (support plate portion 41a). In contrast, the second biasing member 43 is disposed between the shaft support member 41 and the dog member 38, with its front end portion abutting against the rear side surface of the shaft support member 41 and its rear end portion abutting against the front side surface of the dog member 38.

[0044] The operating member body 50 is a resin member whose main raw material is resin, and recycled waste plastic that has been used once can be used as the main raw material. As shown in Figure 6, the operating member main body 50 has a back plate portion 65 (plate portion), a top plate portion 66, a handle portion 67, a reinforcing vertical plate portion 68 (reinforcing portion, first reinforcing portion), a reinforcing horizontal plate portion 69 (second reinforcing portion), and a side wall portion 70, which are formed integrally. For convenience of drawing, reference numerals are assigned only to some of the reinforcing vertical plate portions 68 and some of the reinforcing horizontal plate portions 69, and reference numerals for other similar portions are omitted. Also, in the following description, when there are multiple similar portions, reference numerals will be omitted as necessary.

[0045] The back plate portion 65 is an upright plate-like member having a thickness in a direction including a front-rear direction component (front-rear direction in this embodiment), and more specifically, is a member having a shape that is substantially horizontally elongated in rear view (see FIG. 5). That is, the back plate portion 65 is an upright plate-like portion whose longitudinal direction is the left-right direction.

[0046] The top plate portion 66 is a flat portion that protrudes from the upper portion (the upper end and the portion adjacent to the upper end) of the back plate portion 65. The protruding direction of the top plate portion 66 is a direction that includes a front-to-rear direction component, specifically, a first direction. In other words, the top plate portion 66 protrudes in a direction perpendicular to each of the two main surfaces (both end surfaces in the thickness direction) of the back plate portion 65, and in a direction toward the front.

[0047] As shown in FIG. 7, the handle 67 is a portion that protrudes from the back plate 65, and in this embodiment, it protrudes forward from the lower portion of the back plate 65 (the lower end and the portion adjacent to the lower end). That is, the handle portion 67 in this embodiment protrudes from the back plate portion 65 in the same direction as the top plate portion 66, and its length in the protruding direction (the length in the front-to-back direction, and the length in the left-to-right direction in Figure 7) is the same as that of the top plate portion 66. Furthermore, the thickness direction of the handle portion 67 is a direction that is perpendicular to the protruding direction and that includes a vertical component (vertical direction in this embodiment).

[0048] The handle 67 is integrally formed with a handle base end side portion 67a located on the base end side in the protruding direction and a handle tip end side portion 67b located on the tip end side. In this embodiment, the handle base end side portion 67a is a portion that increases in thickness (length in the vertical direction) toward the tip side in the protruding direction (front side, right side in FIG. 7). In this embodiment, the handle tip side portion 67b is a portion that decreases in thickness (length in the vertical direction decreases) toward the tip side in the protruding direction (the front side, or the right side in FIG. 7). The maximum thickness of the handle tip side portion 67b (the thickness of the portion closest to the base end in the protruding direction) is thicker than the thickness of the back plate portion 65.

[0049] Looking at the top surface of the handle portion 67, the handle portion 67 has, from the rear side (the base end side in the protruding direction of the handle portion 67), a base end flat portion 80 and a curved surface portion 81 (slide guide portion), which form the top surface. The base end flat surface 80 is the portion that becomes the upper surface of the handle base end side portion 67a, and forms a surface that is perpendicular to the thickness direction of the handle portion 67. The curved surface portion 81 is a surface located forward of the base-end flat surface portion 80 (the tip side in the protruding direction of the handle portion 67), and forms a curved surface that curves downward as it moves forward. The curved surface portion 81 forms a curved surface that is convex diagonally upward toward the front and upper side (diagonally upward toward the tip side in the protruding direction of the handle portion 67). In other words, in the part of the handle portion 67 where the curved surface portion 81 forms the upper surface (handle tip side portion 67b), the upper end portion becomes lower as it moves forward.

[0050] The handle 67 also has a front surface 82. The upper end of the front surface 82 is a surface that continues with the lower end of the curved surface 81, and is a plane that is perpendicular to the protruding direction of the handle 67, forming the protruding end surface of the handle 67 and the front surface.

[0051] Here, looking at the underside of the handle portion 67, the handle portion 67 has, from the front (the tip side in the protruding direction of the handle portion 67), a lower inclined portion 83, a lower surface portion 84, a lower first curved surface portion 85, and a lower second curved surface portion 86.

[0052] The lower inclined portion 83 is a portion whose upper end is continuous with the lower end of the front surface portion 82, and forms an inclined surface that gradually slopes upward as it moves forward (toward the tip end of the protruding direction of the handle portion 67). The lower surface portion 84 forms the lower end surface of the handle portion 67, and is a surface perpendicular to the thickness direction (vertical direction) of the handle portion 67, and forms a surface parallel to the base end flat portion 80. The front end portion (the right end portion in FIG. 7) of the lower surface portion 84 is the rear end portion (the left end portion in FIG. 7) of the lower inclined portion 83, and is continuous with the lower end portion. The lower first curved surface portion 85 is a portion separated from the curved surface portion 81 in a diagonal direction (the direction in which the handle portion 67 protrudes and the thickness direction), and forms a curved surface that is convex toward the lower rear. The front end portion of the lower first curved surface portion 85 is continuous with the rear end portion of the lower surface portion 84. The lower first curved surface portion 85 forms a curved surface that is convex toward the upper front. The lower second curved surface portion 86 forms a curved surface that is concave toward the front and upper side. The front end portion, which is the lower end part, of the lower second curved surface portion 86 is continuous with the rear end portion, which is the upper end part, of the lower first curved surface portion 85.

[0053] Here, at least a portion of the lower first curved surface portion 85 is a gently curved portion such that the lower end portion is positioned lower toward the tip end in the protruding direction of the handle portion 67. By providing such a lower first curved surface portion 85, when an operator inserts his / her hand from below the handle portion 67 and places his / her fingers on the curved surface portion 81 to perform a pulling operation, part of the operator's hand (palm, etc.) can easily fit under the handle portion. In other words, at least a portion of the lower first curved surface portion 85 functions as a hand contact portion that fits over part of the operator's hand. This allows the operator to perform the pulling operation more easily.

[0054] 6, the reinforcing vertical plate portion 68 is a vertical plate-like portion that has a thickness in the left-right direction and extends in the up-down direction. The upper end portion of the reinforcing vertical plate portion 68 is continuous and integrated with the underside of the top plate portion 66, the rear end portion is continuous and integrated with the front side surface (the front main surface) of the back plate portion 65, and the lower end portion is continuous and integrated with the base end side flat portion 80 of the handle portion 67.

[0055] Here, a plurality of reinforcing vertical plate portions 68 are provided, and the plurality of reinforcing vertical plate portions 68 are configured by first reinforcing vertical plate portions 68a and second reinforcing vertical plate portions 68b. In detail, the first reinforcing vertical plate portions 68a and the second reinforcing vertical plate portions 68b have different shapes, and the two reinforcing vertical plate portions 68 closest to the center in the longitudinal direction of the operating member body 50 are configured as second reinforcing vertical plate portions 68b. The remaining many reinforcing vertical plate portions 68 are configured as first reinforcing vertical plate portions 68a.

[0056] Of the first vertical reinforcing plate portions 68a, two first vertical reinforcing plate portions 68a located closer to one end than the center in the longitudinal direction of the operating member body 50, and each of the two adjacent first vertical reinforcing plate portions 68a, has a swing shaft insertion hole 90 formed therein. The swing shaft insertion hole 90 is formed in an upper portion of the first vertical reinforcing plate portion 68a (above the center in the up-down direction) and is a hole that penetrates the first vertical reinforcing plate portion 68a in the thickness direction. The swing shaft insertion holes 90 formed in the two first vertical reinforcing plate portions 68a are formed in positions that overlap in the left-right direction.

[0057] Of the first reinforcing vertical plate portions 68a, two first reinforcing vertical plate portions 68a located closer to the other end than the center in the longitudinal direction of the operating member body 50 and two adjacent first reinforcing vertical plate portions 68a also have a swing shaft insertion hole 90 formed in each of them. The two swing shaft insertion holes 90 located closer to one end than the center in the longitudinal direction of the operating member body 50 and the two swing shaft insertion holes 90 located closer to the other end than the center are positioned at the same position in the up-down direction and are formed at positions that overlap in the left-right direction.

[0058] The two swing shaft insertion holes 90 located on one side of the operating member main body 50 in the longitudinal direction function as connecting parts (first connecting parts) that connect to the operating body mounting member 40 (see FIG. 5). Similarly, the two swing shaft insertion holes 90 located on the other side in the longitudinal direction also function as connecting parts that connect to another operating body mounting member 40 (see FIG. 5). In other words, the operating member main body 50 of this embodiment has a total of two connecting parts, one on each side, at the same height and spaced apart in the left-right direction.

[0059] Each of the two second reinforcing vertical plate portions 68b has a connecting shaft insertion hole 91 formed therein. The connecting shaft insertion hole 91 is formed below the oscillation shaft insertion hole 90 in a lower portion of the second reinforcing vertical plate portion 68b (a portion below the center in the up-down direction), and penetrates the second reinforcing vertical plate portion 68b in the thickness direction. The two connecting shaft insertion holes 91 are located at the same position in the up-down direction and are formed at positions that overlap in the left-right direction. This connecting shaft insertion hole 91 functions as a shaft connecting portion (second connecting portion) that connects the shaft member 36 (see FIG. 5). That is, the operating member body 50 of this embodiment has the shaft connecting portion on the lower side near the center in the left-right direction.

[0060] As shown in FIG. 8, the first reinforcing vertical plate portion 68a has a lower constituent portion 95 that constitutes a lower portion including a lower end portion, and an upper constituent portion 96 that constitutes an upper portion. The lower constituent portion 95 is a portion that has a missing portion 99 on the tip side in the first direction (the tip side in the protruding direction of the handle portion 67, see FIG. 7). In other words, the length of the lower constituent portion 95 in the first direction (front-rear direction) is less than the maximum length in the first direction of the first reinforcing vertical plate portion 68a.

[0061] The lower constituent portion 95 of this embodiment has, from above, a first lower constituent portion 95a, a second lower constituent portion 95b, and a third lower constituent portion 95c, which are formed continuously. The first lower component 95a is a portion whose length in the front-to-rear direction (first direction) decreases downward. That is, the front end surface (the end surface on the tip side in the first direction) of the first lower component 95a is an inclined surface that slopes downward and toward the rear. The second lower constituent portion 95b is a portion whose length in the front-to-rear direction (first direction) is constant throughout the entire area in the up-down direction. The second lower constituent portion 95b is also the portion of the first reinforcing vertical plate portion 68a whose length in the front-to-rear direction is the shortest. The third lower component 95c includes the lower end portion of the first reinforcing vertical plate 68a, and its length in the front-to-rear direction (first direction) increases downward. That is, the front end surface (the end surface on the tip side in the first direction) of the third lower component 95c is an inclined surface that slopes forward as it extends downward.

[0062] The third lower constituent portion 95c is a portion of the first reinforcing vertical plate portion 68a (reinforcing portion) adjacent to the upper side of the handle portion 67. The "portion of the reinforcing portion adjacent to the upper side of the handle portion 67" refers to a portion that is 10 mm to 20 mm away from the boundary between the lower portion of the reinforcing portion and the upper portion of the handle portion 67 toward the reinforcing portion, and more preferably, a portion that is 10 mm to 100 mm away. In other words, the portion that is 10 mm or more away, which is approximately the same as the thickness of a typical person's finger (the length from the nail side to the pad side of the finger), and 100 mm or less, which is approximately the same as the length of a typical person's longest finger (the length of the middle finger).

[0063] The upper constituent portion 96 does not lack a tip end in the first direction, and has the same length in the front-to-rear direction (first direction) over the entire vertical area. That is, the upper constituent portion 96 is also the portion of the first reinforcing vertical plate portion 68a whose length in the front-to-rear direction is the greatest. In this embodiment, the upper constituent portion 96 is a portion that is shorter in the vertical direction than the lower constituent portion 95. In other words, the lower constituent portion 95 forms the portion from above the vertical center to the lower end of the first reinforcing vertical plate portion 68a. As described above, in this embodiment, the first reinforcing vertical plate portion 68a has a missing portion 99 located at least in front of the lower end portion and the portion adjacent thereto above, and the lower end portion and its surrounding portion are different from the portion having the shortest length in the front-to-rear direction.

[0064] 9, the second reinforcing vertical plate portion 68b has a lower constituent portion 100 that constitutes a lower portion including a lower end portion, and an upper constituent portion 101 that constitutes an upper portion. The second reinforcing vertical plate portion 68b differs from the first reinforcing vertical plate portion 68a in that the lower constituent portion 100 is shorter in length in the up-down direction than the upper constituent portion 101. In other words, the lower constituent portion 100 forms the portion of the second reinforcing vertical plate portion 68b from below the center in the up-down direction to the lower end.

[0065] The lower component 100 of the second reinforcing vertical plate portion 68b is also a portion having a missing portion 105 at the tip side in the first direction, and has, from the top, a first lower component 100a, a second lower component 100b, and a third lower component 100c, which are formed continuously. The first lower component 100a, the second lower component 100b, and the third lower component 100c are substantially the same as the first lower component 95a, the second lower component 95b, and the third lower component 95c described above, and therefore detailed description thereof will be omitted. Note that the first lower component 100a, the second lower component 100b, and the third lower component 100c differ from the respective components of the lower component 95 described above in terms of their respective vertical lengths and the angles of the inclined surfaces formed on the front end faces of the first lower component 100a and the third lower component 100c.

[0066] The upper component 101 of the second reinforcing vertical plate portion 68b also does not have a missing tip end in the first direction, and is a portion whose length in the front-to-back direction (first direction) is the same throughout the entire area in the up-down direction.

[0067] As described above, in the operation member body 50 of this embodiment, as shown in FIG. 7, an operation gap 108 is formed at a position overlapping the curved surface portion 81 in the up-down direction. 10, the operation gap 108 is a space that includes at least a part of the missing portions 99, 105 of the reinforcing vertical plate portion 68. That is, a part of the operation gap 108 is located below the first reinforcing vertical plate portion 68a (first lower component portion 95a), another part is located below the second reinforcing vertical plate portion 68b (first lower component portion 100a), and still another part is located below the top plate portion 66. As shown in FIG. 6, the operation gap 108 is formed over substantially the entire longitudinal (left-right) area of ​​the operation member main body 50, i.e., the entire longitudinal area excluding the portion where the side wall portion 70 is located.

[0068] 10, in this embodiment, the upper components 96, 101 of the reinforcing vertical plate 68 are positioned in the same front-to-rear direction as the front end surface of the top plate 66 and the front surface 82 of the handle 67. In other words, they are positioned on the same plane (the same imaginary plane).

[0069] As shown in Figure 6, etc., the reinforcing horizontal plate portion 69 is a flat portion arranged between adjacent side wall portions 70 and reinforcing vertical plate portions 68, or between two adjacent reinforcing vertical plate portions 68, so as to connect these side surfaces together. That is, one end of the reinforcing horizontal plate portion 69 in the longitudinal direction (left-right direction) of the operating member main body 50 is continuous and integrated with the side wall portion 70 or one of the reinforcing vertical plate portions 68, and the other end on the opposite side is continuous and integrated with the reinforcing vertical plate portion 68 or the other reinforcing vertical plate portion 68. In addition, the rear end portion of the reinforcing horizontal plate portion 69 is continuous and integrated with the front side surface (front main surface) of the back plate portion 65. As described above, the reinforcing vertical plate portions 68 and the reinforcing horizontal plate portions 69 are disposed in a lattice pattern between the top plate portion 66 and the handle portion 67, and between the two side wall portions 70. In other words, the thickness direction of the reinforcing vertical plate portions 68 and the thickness direction of the reinforcing horizontal plate portions 69 are perpendicular to each other.

[0070] 11(a), the side wall portion 70 is an upright plate-like portion located laterally and outwardly of the reinforcing vertical plate portion 68 and the handle portion 67, has a thickness in the longitudinal direction of the operating member body 50, and extends downward from the lower surface of the top plate portion 66. In other words, the upper portion of the side wall portion 70 is integral with the top plate portion 66. In detail, as shown in FIG. 11(b), the side wall portion 70 has, from above, an upper side wall constituent portion 70a and a lower side wall constituent portion 70b, which are integrally formed.

[0071] The side wall upper constituent portion 70a is a portion that is arranged at a position away from the reinforcing vertical plate portion 68 and has a generally vertically elongated rectangular shape in side view. In detail, the side wall upper constituent portion 70a is a portion whose upper end portion is positioned in the vertical direction at the same position as the upper end portion of the reinforcing vertical plate portion 68 and whose lower end portion is positioned in the vertical direction at the same position as the lower end portion of the reinforcing vertical plate portion 68.

[0072] The side wall lower component 70b is a part arranged on the lateral outer side of the handle portion 67, and the vertical position of the upper end portion is the same as the vertical position of the upper end portion (base end side flat portion 80) of the handle portion 67. That is, the shape of the lower surface of the side wall lower constituent part 70b in a side view is substantially the same as the shape of the lower surface of the handle part 67 in a side view. That is, the lower surface of the side wall lower constituent part 70b and the lower surface of the handle part 67 are a continuous surface that is continuous in the left-right direction (the longitudinal direction of the operating member main body 50), and form the lower surface of the operating member main body 50.

[0073] 11(b), the side wall portion 70 has a side wall inclined surface portion 113 near the lower end. The side wall inclined surface portion 113 forms an inclined surface that gradually slopes upward toward the front (to the right in FIG. 11(b)). The front end surface (the tip end surface in the first direction) of the side wall portion 70 is formed so that its position in the front-to-rear direction is the same except for a portion of the lower end where the side wall inclined surface portion 113 is formed.

[0074] As a result, the front end surface of the side wall upper constituent portion 70a has the same position in the front-to-rear direction throughout the entire vertical range, and the front end surface extends linearly in the vertical direction. The front end surface of the side wall upper constituent portion 70a is located at the same position in the front-to-rear direction as the front end surface of the top plate portion 66, the front end surfaces of the upper constituent portions 96, 101 (upper constituent portion 101 is not shown in FIG. 11 ) of the reinforcing vertical plate portion 68, and the front surface portion 82, and is located on the same plane (the same imaginary plane). In addition, the front end surface of the upper portion of the side wall lower constituent portion 70b forms a continuous surface with the front end surface of the side wall upper constituent portion 70a, and the front end surface of the lower portion is formed by the side wall side inclined surface portion 113.

[0075] From the above, the operating member 35 of this embodiment has a structure in which the handle portion 67, reinforcing vertical plate portion 68, and reinforcing horizontal plate portion 69 are not visible when viewed from the top (planar view), back, or side, which makes it possible to improve the appearance of the garbage collection vehicle 1. Furthermore, as described above, the operating member 35 of this embodiment has the curved surface portion 81, above which the operation gap portion 108 is formed (see FIG. 6, etc.). Therefore, when an operator reaches his / her hand into the lower side of the operating member main body 50, places his / her index finger through little finger on the curved surface portion 81, and grasps and pulls the handle portion 67, the reinforcing vertical plate portion 68 does not get in the way no matter where in the longitudinal direction of the operating member main body 50 the operator inserts his / her fingers. In other words, no matter where in the longitudinal direction of the operating member main body 50 the operator can firmly grasp and pull the handle portion 67, and there is no need to search for an easy-to-grasp location, making operation easy. As described above, the curved surface portion 81 forms a surface that curves gradually downward as it approaches the front side. Therefore, even if foreign matter such as dirt falls unintentionally onto the curved surface portion 81, the foreign matter can easily slide downward. Therefore, foreign matter such as dirt is less likely to remain on the curved surface portion 81, and the occurrence of problems such as foreign matter getting in the way when an operator tries to grasp the handle portion 67 can be suppressed.

[0076] The operating member main body 50 in the above embodiment has been described as an example in which the curved surface portion 81 is formed on the handle portion 67, but the present invention is not limited to this. Below, embodiments different from the above embodiment will be described, but parts similar to those in the above embodiment will be given the same reference numerals and redundant description will be omitted.

[0077] 12, an operating member body 250 according to a second embodiment of the present invention differs from the above-described embodiments in that it has an inclined surface portion 281 (slide guide portion) instead of the curved surface portion 81. In the first state, the inclined surface portion 281 is a portion that forms an inclined surface that slopes downward toward the front (the tip side of the handle portion 267). In this case as well, an operating gap portion 287 is formed above the inclined surface portion 281.

[0078] The operating member body 350 of the third embodiment differs from the above-described embodiments in that, as shown in FIG. 13, the upper surface of the handle portion 367 is a surface that is located on the same imaginary plane from the base end to the tip end in the protruding direction (front-to-back direction). That is, the upper surface of handle 367 is a surface perpendicular to the up-down direction and has an extension in the front-rear and left-right directions. In this case as well, an operation gap 387 is formed above tip-side horizontal portion 381 that constitutes the tip-side portion of the upper surface of handle 367 (the tip-side portion in the protruding direction of handle 367).

[0079] In the above embodiment, an example has been described in which the plate portion is the back plate portion 65 of the operating member body 50, but the present invention is not limited to this. For example, as in an operation member main body 450 of a fourth embodiment shown in FIG. 14 , the plate portion may be a midway plate portion 465 (plate portion) that protrudes downward from a midway portion in the front-to-rear direction of the underside of a top plate portion 466. In addition, in the above-described embodiment, the operation member main body 50 is configured to have a handle portion 67 that protrudes forward from the plate portion. However, the operation member main body 450 may also be configured to have a handle portion 467 that protrudes rearward from the midway plate portion 465 (plate portion) in addition to, or instead of, that. In other words, the operation member main body 450 may be configured to have handle portions 67, 467 that protrude in opposite directions from the plate portion, or may be configured to have either the handle portion 67 that protrudes forward or the handle portion 467 that protrudes rearward.

[0080] Therefore, the operating member main body 450 may be configured to have a reinforcing vertical plate portion 468 (reinforcing portion, first reinforcing portion) and a reinforcing horizontal plate portion 469 (second reinforcing portion) located adjacent to the rear of the plate portion, and a handle portion 467 protruding rearward. The reinforcing vertical plate portion 468 and the reinforcing horizontal plate portion 469 are similar to the reinforcing vertical plate portion 68 and the reinforcing horizontal plate portion 69 described above, except that they extend rearward from the plate portion, and therefore detailed description thereof will be omitted. Moreover, the handle 467 has a curved surface 481 that curves downward as it extends rearward and also curves convexly upward toward the rear. In this case, an operation gap 487 is also formed above the curved surface 481.

[0081] Furthermore, as in the fifth embodiment of the operating member main body 550 shown in Figure 15, the plate portion may be a front plate portion 565 (plate portion) that protrudes downward from the front portion including the front end of the lower surface of the top plate portion 566. The operating member main body 550 has a main body forming portion 550a, a swing side connecting portion 550b (first connecting portion) used to connect to the operating body mounting member 40, and a shaft side connecting portion 550c (second connecting portion) used to connect to the shaft member 36.

[0082] The main body forming portion 550a has a shape that is the front-reverse of the above-described operating member main body 50, and therefore a detailed description thereof will be omitted. That is, in the main body forming portion 550a of this embodiment, the space located between the top plate portion 566 and the handle portion 567 has an opening at the rear, and is a space that is open toward the rear. In other words, the space located between the top plate portion 566 and the handle portion 567 is a space that is open on the opposite side to the space between the top plate portion 66 and the handle portion 67 in the above-described operating member main body 50.

[0083] The swing-side connecting portion 550b is configured by two upright plate-like portions that protrude forward from the front surface of the front plate portion 565. Each of the two upright plate-like portions has a thickness in the left-right direction (the front-rear direction in FIG. 15), is formed at positions spaced apart in the left-right direction, and allows the operation body mounting member 40 to be inserted between them. Each upright plate-like portion also has a shaft insertion hole that penetrates the upright plate-like portion in the thickness direction and through which the swing shaft member 58 can be inserted. In this embodiment, a total of two swing-side connecting portions 550b (one of which is not shown) are provided, one at each position spaced apart in the left-right direction.

[0084] The shaft-side connecting portion 550c is configured by two upright plate-like portions that protrude forward from the front surface of the front plate portion 565. Each of the two upright plate-like portions has a thickness in the left-right direction (the front-rear direction in FIG. 15 ), is formed at positions spaced apart in the left-right direction, and allows the shaft member 36 to be inserted between them. Each upright plate-like portion also has a shaft insertion hole that penetrates the upright plate-like portion in the thickness direction and allows the connecting shaft member 55 to be inserted therethrough.

[0085] In the above embodiment, an example was described in which the length of the reinforcing vertical plate portion 68 in the front-to-rear direction varies from portion to portion. However, the length of the reinforcing vertical plate portion may be constant across the entire vertical area. That is, the front end faces of each portion of the reinforcing vertical plate portion in the vertical direction may be formed to be located on the same plane. In this case, it is sufficient that the front end faces of the reinforcing vertical plate portions are located rearward of the protruding end of the handle portion. In other words, it is sufficient that a gap (operation gap) where the reinforcing vertical plate portion is not located is formed above the protruding end of the handle portion and the portion adjacent to the rear of the protruding end.

[0086] In the above-described embodiment, the front end surfaces of the upper constituent parts 96, 101 of the reinforcing vertical plate part 68 are positioned flush with the front end surface of the side wall upper constituent part 70a in the front-to-rear direction, but the front end surfaces of the upper constituent parts 96, 101 may be positioned rearward of the front end surface of the side wall upper constituent part 70a. In other words, of the front end surfaces of the parts of the reinforcing vertical plate part 68 in the up-down direction, the part positioned most forward may be positioned flush with the front end surface of the side wall upper constituent part 70a in the front-to-rear direction, or may be positioned rearward of the front end surface of the side wall upper constituent part 70a.

[0087] The reinforcing vertical plate portion in the above-described embodiment may have a front end surface with one or more step portions, and the length from the rear end (back plate portion 65) to the front end may be shortened in stages. For example, although not shown in detail, the reinforcing vertical plate portion may have an upper portion, a middle portion, and a lower portion from above, and the length in the front-to-rear direction may be shortened in the order of the upper portion, the middle portion, and the lower portion, and a step may be formed between the front end surfaces of each portion. Furthermore, the reinforcing vertical plate portion of the above-described embodiment may be configured such that the front end surface is gradually positioned further rearward (the length in the front-rear direction is gradually shortened) as it extends downward from the upper end to the lower end.

[0088] In the above embodiment, the operating member 35 has been described as having one operating member body 50, but the present invention is not limited to this. For example, the operating member 35 may have a plurality (two or more) operating member bodies. In this case, the plurality (for example, two) operating member bodies may be arranged side by side in the left-right direction. In this case, the plurality of operating member bodies and one shaft member may be connected via an attachment member, or a configuration may be adopted in which a separate shaft member is connected to each operating member body. In addition, when a configuration is used in which separate shaft members are connected to the operating member main body, the movement of the dog members attached to each separate shaft member (movement of at least a portion of the dog member) may be detected by the same sensor member, or each may be detected by a separate sensor member.

[0089] In the above-described embodiment, the emergency stop device 30 is configured to have one sensor member 39, but the present invention is not limited to this. The emergency stop device may also be configured to have two sensor members 39, one at a position spaced apart in the front-to-rear direction. That is, one sensor member 39 may be configured to detect movement of at least a portion of the dog member 38 due to a pulling operation (approach of at least a portion of the dog member 38), and the other sensor member 39 may be configured to detect movement of at least a portion of the dog member 38 due to a pushing operation. In this case, signals are output from different sensor members 39 when a pulling operation is performed and when a pushing operation is performed.

[0090] In the above-described embodiment, the emergency stop device 30 is configured to be activated by performing one of a pull operation and a push operation. However, the present invention is not limited to this. The emergency stop device may be configured to be activated by a pull operation but not by a push operation, or may be configured to be activated by a push operation but not by a pull operation. If the emergency stop device is configured to be activated by a pull operation rather than a push operation, the emergency stop device may have one sensor member 39 that detects the movement of the dog member 38 due to a pull operation (approach of the dog member 38). Similarly, if the emergency stop device is configured to be activated by a push operation rather than a pull operation, the emergency stop device may have one sensor member 39 that detects the movement of the dog member 38 due to a push operation (approach of the dog member 38). If the emergency stop device is configured to be activated by a push operation rather than a pull operation, using a structure similar to that of the operating member main body 550 of the fifth embodiment described above makes it easier for an operator to grasp the lower portion of the operating member main body 550 (main body forming portion 550a).

[0091] In the above-described embodiment, the curved surface portion 81 and the inclined surface portion 281 are each configured such that their upper ends become lower as they approach the tip end of the handle portion 67, 267 in the protruding direction. However, it is also conceivable that these portions have their upper ends become higher as they approach the tip end of the handle portion 67, 267 in the protruding direction. In other words, the curved surface portion may be configured as a portion that forms a curved surface that curves upward as it approaches the front, and the inclined surface portion may be configured as a portion that forms an inclined surface that slopes upward as it approaches the front. However, from the viewpoint of allowing foreign matter to fall and not remain, it is more preferable to use the curved surface portion 81 and the inclined surface portion 281 described above.

[0092] The handle 67 of the above-described embodiment has a portion whose thickness increases toward the tip in the protruding direction (the portion whose length in the up-down direction in the first state increases, that is, the handle base end portion 67a). With this configuration, when an operator places at least a part of their palm below the handle 67 and places their fingers on the curved surface portion 81 to perform a pulling operation, the operator's palm easily fits under the handle 67, making it easier for the operator to grasp the handle.

[0093] The plate portions (back plate portion, mid-plate portion 465, front plate portion 565) in the above-described embodiment are shown as examples in which the thickness (length in the front-to-rear direction in the first state) of each portion is uniform throughout, but the plate portions may have portions of different thicknesses. The handle may have a uniform thickness (length in the vertical direction in the first state) from the base end to the tip end in the protruding direction. In this case, the thickness of the handle may be thicker than at least a portion of the plate portion. When the thickness of each part of the handle is uniform, the base end part of the handle may extend in a first direction in the first state, and the tip end part may extend in an oblique direction including a first directional component and a downward component. That is, the tip end part of the handle in the direction of protrusion from the plate (first direction) may be bent and extend obliquely downward. Furthermore, if the thickness of each part of the handle (the length in the vertical direction in the first state) is uniform, the thickness of the plate may be uniform throughout, and the thickness of the plate and the thickness of the handle may be the same. Furthermore, in this case, the thickness of the handle may be determined in advance by a sensory test or the like to be a thickness that is easy to grip for an average adult. Specifically, the thickness of the handle may be 13 mm to 45 mm, and more preferably 15 mm to 30 mm.

[0094] In addition, the handle portion may be configured so that the part of the upper surface other than the tip side is a plane perpendicular to the up-down direction in the first state, the lower surface has a shape with one or more step portions, and has a portion where the thickness gradually increases from the base end side to the tip end side in the protruding direction. For example, although detailed illustration is omitted, the handle may be divided into a base end portion, a middle portion, and a tip end portion from the plate portion side, and in the first state, the underside of the middle portion may be lower than the underside of the base end portion, forming a step between them. Similarly, in the first state, the underside of the base end portion of the tip end portion may be lower than the underside of the middle portion, forming a step between them. The middle portion may be thicker than the base end portion, and at least the base end portion of the tip end portion may be thicker than the middle portion. [Explanation of symbols]
