Description

[Technical Field]

[0001] The present invention relates to a work vehicle and a seat. [Background technology]

[0002] Patent Document 1 discloses a multipurpose vehicle that is configured so that the driver's seat or passenger seat can be lifted using the lower front or lower rear part of at least one of the seats as a fulcrum, thereby opening up the upper parts of the storage spaces secured under the driver's seat and passenger seat, allowing items to be taken in and out.

[0003] When the upper portion of the storage space is open, the seat extends vertically relative to the floor of the driver's section. In this state, the surface of the seat above the seating surface has a smaller surface area than the seating surface. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Japanese Patent Application Laid-Open No. 2016-094133 Summary of the Invention [Problem to be solved by the invention]

[0005] As described above, when the seat described in Patent Document 1 is in a state where the upper part of the storage space is open, the surface of the seat above the seating surface has a smaller surface area than the seating surface. As a result, when the upper part of the storage space is open, it is difficult to stably place items on the surface of the seat above the seating surface compared to the seating surface or the surface opposite the seating surface.

[0006] An object of the present invention is to provide a work vehicle and a seat that allows items to be placed stably and easily on the seat when the upper part of the legs is open. [Means for solving the problem]

[0007] A characteristic configuration of a work vehicle for achieving the above object is that it comprises a seat on which an occupant sits, the seat comprising a seat body and legs supporting the seat body, the seat being switchable between a use position in which the seating surface of the seat body faces upward and an inverted position in which the seating surface of the seat body faces downward by rotating the front or rear of the seat body around an axis extending in the width direction of the seat body, In the inverted position, the upper part of the leg is open.

[0008] According to the above characteristic configuration, in the inverted position, the seating surface of the seat body faces downward, so that it is easy to stably place articles and the like on the surface opposite to the seating surface.

[0009] Another characteristic feature of the work vehicle of the present invention is that the seat has a ventilation opening provided at the end opposite the axis in the fore-and-aft direction, and a bracket located above the opening when in the inverted position, and the rotation of the seat is stopped when the bracket abuts against the body of the vehicle.

[0010] According to the above-mentioned characteristic configuration, the bracket stops the rotation of the seat body at any position. In addition, in the opposite position, the bracket is located above the opening, making it difficult for rain and other elements to get into the opening.

[0011] Another characteristic feature of the work vehicle according to the present invention is that the rotation of the seat body is stopped when the side of the seat body on the axis side in the front-to-rear direction abuts against the leg.

[0012] According to the above characteristic configuration, the rotation of the seat body is stopped with a simple configuration while minimizing the number of additional parts.

[0013] Another characteristic feature of the work vehicle of the present invention is that in the use position, the seat is placed on the upper surface of the legs, and in the inverted position, the upper surface of the legs and the surface of the seat opposite the seating surface are flush with each other.

[0014] According to the above characteristic configuration, in the inverted position, the upper surface of the legs and the surface opposite the seating surface are flush with each other, making it easier to place items in the item placement space spanning the legs and the seat.

[0015] Another characteristic feature of the work vehicle according to the present invention is that the legs have an article storage section recessed downward from the upper surface of the legs.

[0016] According to the above characteristic configuration, by storing items in the item storage section that recesses downward from the top surface of the leg, even if the work vehicle shakes, the items are less likely to fall off the seat compared to when the items are placed directly on the top surface of the leg.

[0017] Another characteristic feature of the work vehicle of the present invention is that it further comprises a boarding section in which occupants board, the boarding section comprising a driver's seat in which the driver sits and a rear seat located rearward of the driver's seat, the width of the rear seat being at least twice the width of the driver's seat.

[0018] According to the above-mentioned characteristic configuration, in the inverted position, items can be stably placed on the side of the seat body opposite the seating surface, which is more than twice the width of the driver's seat. In other words, in the inverted position, a large item placement space can be secured above the seat body.

[0019] The characteristic configuration of a seat for achieving the above-mentioned object is that it comprises a seat body on which an occupant sits and legs that support the seat body, and by rotating the front or rear of the seat body around an axis extending in the width direction of the seat body, it is possible to switch between a use position in which the seating surface of the seat body faces upward and an inverted position in which the seating surface of the seat body faces downward, and in the inverted position the upper part of the legs is open.

[0020] According to the above characteristic configuration, in the inverted position, the seating surface of the seat body faces downward, so that it is easy to stably place articles and the like on the surface opposite to the seating surface. [Brief explanation of the drawings]

[0022] A multipurpose vehicle, which is an example of a work vehicle according to the present invention, will be described below with reference to the drawings. In the following description, the direction of arrow F in the drawings will be referred to as the "front side," the direction of arrow B as the "rear side," the direction of arrow U as the "upper side," the direction of arrow D as the "lower side," the direction of arrow R as the "right side," and the direction of arrow L as the "left side."

[0023] [Overall structure] As shown in Figure 1, the work vehicle body 100 comprises a body frame 1, a running device 2 that supports the body frame 1, a bonnet 3, a passenger section 4 where the occupants sit, a dump-type cargo bed 6, and an engine E.

[0024] The traveling device 2 is equipped with left and right front wheels 21 that are steerable and drivable, and left and right rear wheels 22 that are not steerable and drivable. The front wheels 21 support the front part of the vehicle frame 1. The rear wheels 22 support the rear part of the vehicle frame 1. The traveling device 2 is configured to be switchable between a two-wheel drive state in which only the left and right rear wheels 22 are driven, and a four-wheel drive state in which the left and right front wheels 21 and the left and right rear wheels 22 are driven.

[0025] The riding section 4 is located between the left and right front wheels 21 and the left and right rear wheels 22 in a side view. The riding section 4 is supported by the vehicle frame 1.

[0026] The bonnet 3 is located in front of the passenger section 4. The luggage compartment 6 is located behind the passenger section 4. The bonnet 3 houses a radiator that cools the coolant for the engine E and the like.

[0027] Power from the engine E is transmitted to the front wheels 21 or the rear wheels 22 after being changed in speed by the transmission T. The engine E and the transmission T are located below the bed 6.

[0028] [Boarding section] As shown in Figures 1 and 2, the riding section 4 includes a steering handle 41 for steering the left and right front wheels 21, a ROPS (Rollover Protective Structure) 42 for protecting the occupants, a floor panel 43 that forms the floor surface of the riding section 4, and various operating tools such as a gear shift lever for shifting gears.

[0029] The passenger area 4 includes a driver's seat 5O where the driver sits, a front seat 5F located to the side of the driver's seat 5O where the occupant sits, and a rear seat 5R (corresponding to a seat) located behind the driver's seat 5O and the front seat 5F.

[0030] The width of the rear seat 5R is at least twice the width of the driver's seat 5O. In this embodiment, the width of the rear seat 5R is three times the width of the driver's seat 5O. In other words, the driver's seat 5O is a seat for one person, and the rear seat 5R is a seat for three people. However, the width of the rear seat 5R may be twice the width of the driver's seat 5O.

[0031] The driver's seat 50 is located behind the steering wheel 41.

[0032] A ROPs 42 is provided around the passenger section 4. The ROPs 42 is connected to the aircraft frame 1 and surrounds the driver's seat 5O, the front seat 5F, and the rear seat 5R.

[0033] The floor panel 43 is supported by the vehicle frame 1.

[0034] [Rear seat] 3 and 4, the rear seat 5R includes a seat body 51 on which an occupant sits, legs 52 that support the seat body 51, and a back portion 53 that is located behind the seat body 51. The back portion 53 is fixed to the left and right ROPs 42.

[0035] The rear seat 5R can be switched between a use position P1 in which the seating surface 51a of the seat body 51 faces upward and an inverted position P2 (see Figure 6) in which the seating surface 51a of the seat body 51 faces downward by rotating the front part of the seat body 51 around an axis A1 extending in the width direction of the seat body 51.

[0036] [Seat] As shown in Figures 5, 6, and 7, seat body 51 is made of a water-repellent sheet-like member that encases a foam such as urethane foam. The seating surface 51a of seat body 51 has an exposed sheet-like member and provides cushioning. At least surface 51b of seat body 51 opposite seating surface 51a is covered with a resin cover.

[0037] The seat body 51 has a recess 51c recessed from the surface 51b opposite the seat surface 51a toward the seat surface 51a, a ventilation opening 51d provided at the end opposite the axis A1 in the front-to-rear direction, and a plate-shaped bracket 51e.

[0038] A plurality of recesses 51c are formed at intervals in the width direction of the seat body 51 at the front end of the surface 51b opposite the seating surface 51a. In this embodiment, the number of recesses 51c is three. However, the number of recesses 51c is not limited to three, and may be any number.

[0039] The openings 51d are ventilation openings for allowing air to pass through the seat body 51. A plurality of openings 51d are formed at the bottom of each recess 51c. In this embodiment, two openings 51d are formed at the front end of each recess 51c. This is not limited to this, and the number of openings 51d formed in each recess 51c is arbitrary. The openings 51d extend from the surface 51b opposite the seating surface 51a toward the seating surface 51a. The openings 51d also penetrate the cover of the surface 51b opposite the seating surface 51a.

[0040] 6, bracket 51e is located above opening 51d in inverted posture P2. Each bracket 51e is fixed to the surface 51b opposite seating surface 51a by a bolt at the bottom of each recess 51c. In other words, a plurality of brackets 51e are formed at the front end of surface 51b opposite seating surface 51a at intervals in the width direction of base body 51.

[0041] The bracket 51e extends to the front side of the machine body 100 and then bends obliquely upward in front of the machine body 100.

[0042] As shown in Fig. 5, the work vehicle is equipped with a hinge 7 that rotatably supports a seating body 51. The hinge 7 has a first member 7a fixed to a surface 51b opposite to the seating surface 51a, and a second member 7b fixed to the front surface of the leg 52. The first member 7a is configured to be rotatable around an axis A1 relative to the second member 7b.

[0043] 〔leg〕 As shown in Figures 6 and 7, the leg 52 has a leg frame 52a that supports the seat body 51, a cover member 52b that covers the leg frame 52a, and an item storage section 52c that is recessed downward from the upper surface of the leg 52.

[0044] The leg frame 52a is supported by the body frame 1. The leg frame 52a has multiple upper and lower frames extending vertically from the body frame 1, and an upper frame connected to the upper ends of the upper and lower frames and having a lattice shape in a plan view. The upper frame extends in the width direction of the rear seat 5R.

[0045] The cover member 52b is formed by molding a sheet-like member made of resin. The cover member 52b covers the leg frame 52a from above. The cover member 52b also covers the leg frame 52a from the front. In other words, the cover member 52b forms the upper surface of the leg 52. The cover member 52b also forms the front surface of the leg 52.

[0046] A plurality of article storage sections 52c are formed on the upper surface of the leg section 52 at intervals in the width direction of the leg section 52.

[0047] [Regarding rear seat position changes] 3, in the use position P1 of the rear seat 5R, the seat body 51 rests on the upper surface of the legs 52. In the use position P1, the seat body 51 can rotate clockwise around the axis A1 by the hinge 7.

[0048] In the use position P1, the rear of the seat body 51 is manually rotated clockwise around the axis A1. As shown in FIG. 6, the rotation of the seat body 51 is stopped when each bracket 51e abuts against the left and right frames 42a that are part of the front seat 5F. The left and right frames 42a extend in the left-right direction across the left and right ROPs 42. In other words, the rotation of the seat body 51 is stopped when the bracket 51e abuts against the left and right frames 42a of the vehicle body 100. The rotation of the seat body 51 is also stopped when the side of the seat body 51 on the axis A1 side in the front-rear direction abuts against the front of the leg 52.

[0049] As a result, the rear seat 5R assumes an inverted position P2. In the inverted position P2, the upper part of the leg portion 52 is open. In other words, in the inverted position P2, the seat body 51 is in a position that does not overlap with the upper surface of the leg portion 52 in a plan view. Specifically, in the inverted position P2, the surface 51b opposite the seating surface 51a is positioned forward of the upper surface of the leg portion 52. Also, in the inverted position P2, the upper surface of the leg portion 52 and the surface 51b opposite the seating surface 51a of the seat body 51 are flush with each other. In other words, in the inverted position P2, the surface 51b opposite the seating surface 51a is positioned at the same height as the upper surface of the leg portion 52. In the inverted position P2, the angle formed by the upper surface of the leg portion 52 and the surface 51b opposite the seating surface 51a is approximately 180 degrees.

[0050] As described above, in the inverted posture P2, the seating surface 51a faces downward. Here, the term "downward" in the claims includes at least a downward diagonal direction in front and a downward diagonal direction in rear.

[0051] [Another embodiment] The present invention is not limited to the above-described embodiment. For example, the following other embodiments may be used. In the other embodiments described below, the same components as those in the above-described embodiment are assigned the same numbers and symbols.

[0052] [1] In the above-described embodiment, the front seat 5F is switchable between the use position P1 and the inverted position P2. This is not limiting, and the front seat 5F (corresponding to the seat) may be switchable between the use position P1 and the inverted position P2. In other words, at least one of the front seat 5F and the front seat 5F may be switchable between the use position P1 and the inverted position P2.

[0053] [2] In the above embodiment, the width of the rear seat 5R is more than twice the width of the driver's seat 5O. However, the width of the rear seat 5R may be the same as the width of the driver's seat 5O. In other words, the rear seat 5R may be a single-seat seat.

[0054] [3] In the above-described embodiment, the front part of the seat support 51 of the rear seat 5R rotates around the axis A1 toward the front of the aircraft body 100. However, the rear part of the seat support 51 of the rear seat 5R may rotate around the axis toward the rear of the aircraft body 100. In this case, the rear seat 5R does not need to have a back 53.

[0055] [4] In the above-described embodiment, the base body 51 has plate-shaped brackets 51e. However, the brackets 51e may have other shapes. For example, each bracket 51e may be an arm-shaped member whose tip abuts against the left and right frames 42a.

[0056] [5] In the above embodiment, the brackets 51e are provided in the recesses 51c. However, the present invention is not limited to this. The brackets 51e may be provided at locations other than the recesses 51c on the surface 51b opposite to the seating surface 51a.

[0057] [6] In the above-described embodiment, the opening 51d is formed on the surface 51b opposite to the seating surface 51a. However, the opening 51d may be formed on the side surface of the seat body 51 opposite to the axis A1 in the front-rear direction.

[0058] [7] In the above-described embodiment, the leg 52 has an item storage section 52c recessed downward from the upper surface of the leg 52. However, this is not limiting, and the leg 52 does not necessarily have to have the item storage section 52c. In other words, the entire upper surface of the leg 52 may be flat.

[0059] [8] In the above-described embodiment, in the inverted posture P2, the upper surface of the leg 52 and the surface 51b opposite to the seating surface 51a are flush with each other. However, this is not limiting, and in the inverted posture P2, there may be a step between the upper surface of the leg 52 and the seating surface 51a.

[0060] [9] The leg 52 may have left and right side panels located at the left and right outer ends of the leg 52, a front panel extending from the front end of the left side panel to the front end of the right side panel, and a rear panel extending from the rear end of the left side panel to the rear end of the right side panel. In this case, the space surrounded by the left and right side panels, the front panel, and the rear panel may be an item storage area.

[0061]

[10] In the above-described embodiment, in the inverted position P2, the angle formed between the upper surface of the leg 52 and the surface 51b opposite the seating surface 51a is approximately 180 degrees. However, the angle formed between the upper surface of the leg 52 and the surface 51b opposite the seating surface 51a in the inverted position P2 may be any angle equal to or greater than 90 degrees. For example, in the inverted position P2, the angle formed between the upper surface of the leg 52 and the surface 51b opposite the seating surface 51a may be approximately 120 degrees. In this case, the rotation of the seat body 51 is stopped only by the bracket 51e abutting against the left and right frames 42a. In other words, in the inverted position P2, the side of the seat body 51 on the axis A1 side in the front-to-rear direction does not abut against the front surface of the leg 52. In this embodiment, the seating surface 51a faces diagonally downward and forward in the inverted position P2.

[0062]

[11] In the above-described embodiment, a multipurpose vehicle is shown as an example of a work vehicle. However, the present invention is not limited to this and can be applied to work vehicles such as combine harvesters, tractors, rice transplanters, paddy field direct seeding machines, corn harvesters, potato harvesters, carrot harvesters, sugarcane harvesters, construction machines, etc.

[0063]

[12] The configurations disclosed in the above-described embodiments (including other embodiments, the same applies below) can be applied in combination with configurations disclosed in other embodiments, unless a contradiction arises. Furthermore, the embodiments disclosed in this specification are merely examples, and the embodiments of the present invention are not limited thereto and can be appropriately modified within the scope of the purpose of the present invention.
