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 includes an upwardly opening storage compartment mounted on a seat support base, and a seat body that constitutes a driver's seat that can be flipped up around a horizontal support shaft on the rear side of the seat body to open and close the storage compartment. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2010-95106 Summary of the Invention [Problem to be solved by the invention]

[0004] When the seat described in Patent Document 1 rotates downward from a raised position, the speed at which the seat rotates downward increases due to its own weight. If the seat rotates downward at a high speed, the impact will be greater if it comes into contact with luggage placed in an item storage section or the like.

[0005] SUMMARY OF THE INVENTION An object of the present invention is to provide a work vehicle and a seat that are capable of slowing down the speed at which the seat body rotates downward. [Means for solving the problem]

[0006] A characteristic configuration of a work vehicle for achieving the above-mentioned 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 seat body extends in the front-to-back direction and a storage position in which the seat body extends in the up-and-down direction by rotating the front part of the seat body in the up-and-down direction, one of the seat body or the legs having a guided member that protrudes in the width direction of the seat, and the other of the seat body or the legs having a guide member that guides the guided member with at least a portion of the guided member in contact with it.

[0007] According to the above-described characteristic configuration, when the front portion of the seat body rotates downward, the guided member is guided with a part of the guided member in contact with the guiding member, thereby slowing down the speed of the seat body rotating downward.

[0008] Another characteristic feature of the work vehicle of the present invention is that the guided member is a pin-shaped member provided on the base body, and the guiding member is a groove-shaped member provided on the leg portion and into which the guided member is inserted.

[0009] According to the above-described characteristic configuration, when the seat rotates up and down, the guided member is inserted into the guide member and guided along the guide member, thereby slowing down the speed of the seat body rotating downward.

[0010] Another characteristic feature of the work vehicle of the present invention is that the seat can be switched from the storage position to the usage position by rotating the front part of the seat body downward from the storage position, and the position of the guided member in the storage position is lower than the position of the guided member in the usage position.

[0011] According to the above-described characteristic configuration, when the seat is switched from the storage position to the usage position, the guided member needs to be guided in a direction against gravity by the guiding member, which slows the speed of the seat body rotating downward compared to a configuration in which the position of the guided member in the storage position is higher than the position of the guided member in the usage position.

[0012] Another characteristic feature of the work vehicle according to the present invention is that the guide member extends with a downward slant toward the front.

[0013] According to the above-mentioned characteristic configuration, when the seat is switched from the storage position to the usage position, the guided member is guided diagonally upward and rearward along the guide portion by the rotation of the seat body. As a result, the guided member needs to be guided in a direction against gravity, so the speed of the seat body rotating downward when the seat is switched from the storage position to the usage position slows down.

[0014] Another characteristic feature of the work vehicle according to the present invention is that the guide member has an engagement portion that is formed at the position of the guided member in the storage position and that bulges downward from the guide member.

[0015] If the work vehicle brakes suddenly while the seat is in the stowed position, a force is applied to the seat body in the forward direction. This may cause the seat to unintentionally switch to the in-use position. According to the above characteristic configuration, the guided member engages with the engagement portion in the stowed position. As a result, when the seat is switched from the stowed position to the in-use position, the seat body must be lifted upward to disengage the guided member from the engagement portion. Therefore, the seat body is less likely to rotate downward unintentionally when the work vehicle brakes suddenly, for example.

[0016] Another characteristic feature of the work vehicle of the present invention is that the legs have a plurality of first members located below the seat body and extending in the vertical direction, and a second member extending in the width direction of the seat and connecting the plurality of first members, and the lower part of the seat body abuts against the second members in the use position, and the rear end of the second members is located forward of the front end of the seat body in the storage position.

[0017] When the seat is switched from the in-use position to the stored position, the guided member is guided diagonally forward and downward along the guiding member. That is, a portion of the seat body in the stored position is positioned lower than the seat body in the in-use position. As a result, when the seat is switched from the in-use position to the stored position, a portion of the seat body may come into contact with the legs. According to the above characteristic configuration, the rear end of the second member is positioned further forward than the front end of the seat body in the stored position, so when the seat is switched from the in-use position to the stored position, a portion of the seat body does not come into contact with the second member.

[0018] Another characteristic configuration of the work vehicle of the present invention is that the seat further comprises a back, and the seat body further comprises a first end which is the end on the back side in the usage position, and a second end which is the end opposite the first end, the seat body has, as the guided members, a first guided member and a second guided member which is at a greater distance from the second end than the first guided member, and the legs have, as the guide members, a first guide member which extends with an upward slope towards the front and guides the first guided member, and a second guide member which extends with a downward slope towards the front and guides the second guided member.

[0019] According to the above characteristic configuration, when the seat is switched from the stored position to the usage position, the first guided member is guided diagonally upward and forward along the first guide portion. Also, the second guided member is guided diagonally upward and rearward along the second guide portion. As a result, since the first guided member and the second guided member need to be guided in a direction against gravity, the speed at which the seat body rotates downward when the seat is switched from the stored position to the usage position slows down.

[0020] Another characteristic feature of the work vehicle of the present invention is that the distance from the lower end of the first guide member to the rear end of the second guide member in a side view is approximately equal to the distance from the lower end of the first guide member to the front end of the second guide member in a side view.

[0021] According to the above characteristic configuration, the distance between the first guided member and the second guided member is constant. In other words, the distance between the portion of the first guiding member where the first guided member is guided and the portion of the second guiding member where the second guided member is guided is constant, which makes it easier for the first guided member and the second guided member to be appropriately guided by the first guiding member and the second guiding member.

[0022] The characteristic configuration of a seat for achieving the above-mentioned object is a seat that comprises a seat body on which an occupant sits and legs that support the seat body, and that can be switched between a use position in which the seat body extends in the front-to-back direction and a storage position in which the seat body extends in the up-and-down direction by rotating the front part of the seat body in the up-and-down direction, wherein one of the seat body or the legs has a guided member that protrudes in the width direction of the seat, and the other of the seat body or the legs has a guiding member that is positioned around the center of rotation and guides the guided member with at least a portion of the guided member in contact with it.

[0023] According to the above-described characteristic configuration, when the front portion of the seat body rotates up and down, the guided member is guided with a part of the guided member in contact with the guiding member, thereby slowing down the speed of the seat body rotating downward.

[0033] The driver's seat 50 is located behind the steering wheel 41.

[0034] A front door 42 is located on the outer side of the aircraft body 100 of the driver's seat 5O and the front seats 5F. Also, a rear door 42 is located on the outer side of the aircraft body 100 of the rear seat 5R.

[0035] A rope protector 43 is provided around the passenger compartment 4. The lower end of the rope protector 43 is connected to the aircraft frame 1, and surrounds the driver's seat 5O, the front seat 5F, and the rear seat 5R.

[0036] The floor panel 44 is supported by the body frame 1.

[0037] [Front seat] As shown in Figures 2 and 3, the front seat 5F includes a seat body 51 on which an occupant sits, legs 52 that support the seat body 51, a back 53, and a buckle 54 to which a seat belt can be fastened.

[0038] 3, the front seat 5F can be switched between a usage position P1 in which the seat body 51 extends in the front-to-rear direction, a storage position P2 in which the seat body 51 extends in the vertical direction, and an intermediate position P3 in which the seat body 51 is positioned midway between the seat body 51 in the usage position P1 and the seat body 51 in the storage position P2, by rotating the front part of the seat body 51 downward from the storage position P2. In this embodiment, the front seat 5F can be switched to the usage position P1 by rotating the front part of the seat body 51 downward from the storage position P2.

[0039] 2, a recess 51f is formed in the rear part of the center of the left and right of the seat body 51. The recess 51f is formed from the rear end of the seat body 51 toward the center of the front and rear of the seat body 51.

[0040] 〔leg〕 Legs 52 support the seat body of driver seat 5O and seat bodies 51 of front seats 5F. As shown in Figures 3 and 4, legs 52 include a plurality of first members 52a located below seat body 51 and extending in the vertical direction, second members 52b extending in the width direction of front seats 5F and connecting the plurality of first members 52a, third members 52c extending in the vertical direction and located laterally inward of aircraft body 100 than first members 52a, fourth members 52i located rearward of second members 52b and extending in the width direction of front seats 5F, connecting members 52h extending in the depth direction of front seats 5F and connecting second members 52b and fourth members 52i, first guide members 52d (corresponding to guide members), and second guide members 52e (corresponding to guide members).

[0041] The first member 52a is a plate-shaped member extending in the front-to-rear direction of the aircraft body 100. As shown in Fig. 2, the left and right first members 52a are located laterally outside the aircraft body 100 of the driver's seat 5O and the front seat 5F. Specifically, the right first member 52a is located on the right outer side of the front seat 5F. The left first member 52a is located on the left outer side of the driver's seat 5O.

[0042] The second member 52b and the fourth member 52i are provided at positions spaced apart from each other in the front-rear direction. The right end of the second member 52b is fixed to the front part of the right first member 52a. The left end of the second member 52b is fixed to the front part of the left first member 52a.

[0043] The right end of the fourth member 52i is fixed to the rear part of the right first member 52a. The left end of the fourth member 52i is fixed to the rear part of the left first member 52a. In addition, the upper part of the third member 52c is fixed to the left-right intermediate part of the fourth member 52i.

[0044] [Guide member] The left and right first guide members 52d and the left and right second guide members 52e are groove-shaped members located on the outer lateral sides of the seat body 51. Specifically, the right first guide member 52d and the right second guide member 52e are located on the right outer side of the seat body 51 and are formed on a plate-shaped bracket fixed to the upper end of the first member 52a. The left first guide member 52d and the left second guide member 52e are located on the left outer side of the seat body 51 and are formed on a plate-shaped bracket fixed to a connecting member 52h.

[0045] The first guide member 52d extends with an upward incline toward the front. The second guide member 52e extends with a downward incline toward the front. The second guide member 52e includes a front engagement portion 52f (corresponding to an engagement portion) that bulges downward from the front end of the second guide member 52e, and a rear engagement portion 52g that bulges downward from the rear end of the second guide member 52e.

[0046] [Back] The back 53 is located behind the seat 51 and extends diagonally upward and rearward. As shown in Fig. 5, the back 53 is fixed to the left and right ROPS 43 by rod-shaped support members 53a extending in the left-right direction of the body 100. The back 53 is also fixed to the fourth member 52i by rod-shaped support members 53a extending in the up-down direction of the body 100.

[0047] As shown in Fig. 2, the buckle 54 is located at the left-right center of the seat body 51. The buckle 54 is rotatable around an axis A1 that extends in the width direction of the front seat 5F. The buckle 54 rotates upward together with the seat body 51 when the upper surface of the seat body 51 comes into contact with the buckle 54 as it rotates upward.

[0048] The buckle 54 is located at a position corresponding to the recess 51f of the seat body 51 in a plan view. The buckle 54 passes through the recess 51f of the seat body 51 and protrudes above the upper surface of the seat body 51.

[0049] [Seat] 3 and 4, seat body 51 has a width that allows multiple people to sit on it. Seat body 51 has a seat body frame 51c located at the bottom of seat body 51, a first guided member 51a (corresponding to the guided member) that protrudes in the width direction of front seat 5F, and a second guided member 51b (corresponding to the guided member) that protrudes in the width direction of front seat 5F.

[0050] [Guided member] As shown in FIGS. 3 and 4, the first guided member 51a and the second guided member 51b are pin-shaped members extending laterally outward from the machine body 100. The left and right first guided members 51a and the left and right second guided members 51b are provided on the laterally outer portions of the seat body 51. Specifically, the right first guided member 51a and the right second guided member 51b are provided on the right outer end of the seat body 51. The left first guided member 51a and the left second guided member 51b are provided on the left outer end of the seat body 51. The base end of the first guided member 51a and the base end of the second guided member 51b are fixed to the seat body frame 51c.

[0051] The first guided member 51a is inserted into the first guiding member 52d. The first guiding member 52d guides the first guided member 51a in a state where at least a portion of the first guided member 51a is in contact with the first guiding member 52d. In other words, the first guided member 51a is guided along the first guiding member 52d.

[0052] The second guided member 51b is inserted into the second guiding member 52e. The second guiding member 52e guides the second guided member 51b in a state where at least a portion of the second guided member 51b is in contact with the second guiding member 52e. In other words, the second guided member 51b is guided along the second guiding member 52e.

[0053] A link mechanism is formed by the base 51, the legs 52, the first guided member 51a, the second guided member 51b, the first guiding member 52d, and the second guiding member 52e. The first guided member 51a and the second guided member 51b are spaced a fixed distance apart.

[0054] 3, in the use position P1, the seat body 51 has a first end 51d which is a side end on the back portion 53 side, and a second end 51e which is a side end opposite the first end 51d. The second guided member 51b is at a greater distance from the second end 51e than the first guided member 51a.

[0055] 6, the distance L1 from the bottom end of the first guide member 52d to the rear end of the second guide member 52e in a side view is substantially equal to the distance L2 from the bottom end of the first guide member 52d to the front end of the second guide member 52e in a side view. Distances L1 and L2 correspond to the distances from the end of the first guided member 51a facing the second guided member 51b to the end of the second guided member 51b on the opposite side from the first guided member 51a. Furthermore, the distance L3 from the top end of the first guide member 52d to the front-to-rear middle of the second guide member 52e in a side view corresponds to the distance from the end of the first guided member 51a on the opposite side from the second guided member 51b to the end of the second guided member 51b on the opposite side from the first guided member 51a.

[0056] [Regarding changing the position of the front seats] 6, 7, and 8, when the front part of the base body 51 is manually rotated, the first guided member 51a moves within the first guiding member 52d, and the second guided member 51b moves within the second guiding member 52e.

[0057] As shown in FIG. 6, in the use position P1, the first guided member 51a is located at the lower end of the first guide member 52d. Furthermore, in the use position P1, the second guided member 51b is located at the rear end of the second guiding member 52e. The second guided member 51b engages with the rear engagement portion 52g in the use position P1. In other words, the rear engagement portion 52g is formed at the position of the second guided member 51b in the use position P1. In the use position P1, the upper surface of the seat body 51 faces upward. As shown in FIG. 3, the front end of the second member 52b is located rearward of the front-to-rear middle portion of the seat body 51 in the use position P1.

[0058] The front seat 5F in the use position P1 is brought into the storage position P2 by manually lifting the front portion of the seat body 51 diagonally upward and forward and then rotating it upward. Specifically, in the use position P1, the front portion of the seat body 51 is lifted diagonally upward and forward, causing the first guided member 51a to be guided diagonally upward and forward within the first guiding member 52d. Furthermore, in the use position P1, the front portion of the seat body 51 is lifted diagonally upward and forward, causing the second guided member 51b to disengage upward from the rear engagement portion 52g.

[0059] Next, the front portion of the base body 51 is manually rotated upward, which applies a counterclockwise force to the first guided member 51a. The first guided member 51a moves diagonally forward and upward along the first guide member 52d. As the first guided member 51a moves diagonally forward and upward, the second guided member 51b moves diagonally forward and downward along the second guide member 52e. The first guided member 51a abuts against the upper end of the first guide member 52d and temporarily stops.

[0060] As shown in Fig. 7, when the front of the seat support 51 is rotated upward from the usage position P1, it assumes an intermediate position P3. In the intermediate position P3, the upper surface of the seat support 51 faces diagonally upward and rearward of the vehicle body 100. As shown in Fig. 3, in a side view, an angle θ1 formed by a line V1 extending along the lower end of the seat support 51 in the usage position P1 and a line V3 extending along the lower end of the seat support 51 in the intermediate position P3 is approximately 50 degrees.

[0061] The first guided member 51a is located at the upper end of the first guide member 52d in the intermediate position P3, and the second guided member 51b is located at the front-rear intermediate portion of the second guide member 52e in the intermediate position P3.

[0062] When the front portion of the base body 51 in the intermediate position P3 is rotated upward, a counterclockwise force is applied to the first guided member 51a. The counterclockwise movement of the first guided member 51a is restricted by the first guide member 52d. As a result, a counterclockwise force is applied to the second guided member 51b, with the first guided member 51a as the fulcrum. In other words, the second guided member 51b moves diagonally forward and downward within the second guide member 52e. As the second guided member 51b moves diagonally forward and downward, the first guided member 51a moves diagonally backward and downward along the first guide member 52d. The first guided member 51a comes into contact with the lower end of the first guide member 52d and stops. The second guided member 51b also comes into contact with the front end of the second guide member 52e and stops.

[0063] As shown in FIG. 8, the seat support 51 stops when its upper surface abuts against the backrest 53. In the storage position P2, the upper surface of the seat support 51 faces the rear of the aircraft body 100. As shown in FIG. 3, in a side view, the angle θ2 formed by a line V1 extending along the lower end of the seat support 51 in the use position P1 and a line V2 extending along the lower end of the seat support 51 in the storage position P2 is approximately 100 degrees. This shifts the center of gravity of the seat support 51 rearward compared to a configuration in which the angle θ2 is 90 degrees, making it easier for the seat support 51 to rotate in a direction that widens the angle θ2 due to its own weight. In other words, the seat support 51 is less likely to rotate forward and downward. This is preferable because it makes it less likely for the front seat 5F in the storage position P2 to be unintentionally changed to the use position P1.

[0064] The first guided member 51a is located at the lower end of the first guide member 52d in the storage position P2. The second guided member 51b is located at the front end of the second guide member 52e in the storage position P2. The second guided member 51b engages with the front engagement portion 52f in the storage position P2. In other words, the front engagement portion 52f is formed at the position of the second guided member 51b in the storage position P2. The position of the second guided member 51b in the storage position P2 is lower than the position of the second guided member 51b in the use position P1.

[0065] 8, the rear end of the second member 52b is located further forward than the front end of the seat support 51 in the storage position P2. The first end 51d of the seat support 51 is located between the second member 52b and the fourth member 52i. When the front seat 5F is in the storage position P2, luggage can be placed in the area surrounded by the front end of the second member 52b, the floor panel 44, and the front panel in front of the front seat 5F.

[0066] The front seat 5F in the storage position P2 is placed in the use position P1 by manually lifting the front portion of the seat support 51 diagonally upward and forward and then rotating it downward. That is, in the storage position P2, the front portion of the seat support 51 is lifted diagonally upward and forward, so that the first guided member 51a is guided diagonally upward and forward within the first guiding member 52d. Also, in the storage position P2, the front portion of the seat support 51 is lifted diagonally upward and forward, so that the second guided member 51b disengages upward from the front engagement portion 52f.

[0067] Next, the front of the seat body 51 is rotated downward, applying a clockwise force to the first guided member 51a. The first guided member 51a moves diagonally forward and upward along the first guide member 52d. As the first guided member 51a moves diagonally forward and upward, the second guided member 51b moves diagonally backward and upward along the second guide member 52e. Subsequently, the front seat 5F reaches the usage position P1 by following the procedure described above in reverse. In the usage position P1, the lower part of the seat body 51 abuts against the upper surface of the second member 52b. This stops the rotation of the seat body 51 in the usage position P1.

[0068] [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.

[0069] [1] In the above-described embodiment, the front seat 5F is switchable between a use position P1 and a storage position P2. However, the present invention is not limited to this. The driver's seat 5O may be switchable between a use position P1 and a storage position P2. The rear seat 5R may be switchable between a use position P1 and a storage position P2.

[0070] [2] In the above-described embodiment, the seat body 51 includes the first guided member 51a and the second guided member 51b, and the legs 52 include the first guide member 52d and the second guide member 52e. However, the present invention is not limited to this. The seat body 51 may include the first guide member and the second guide member, and the legs 52 may include the first guided member and the second guided member. In this case, the first guide member and the second guide member are formed on the left and right lateral outer end portions of the seat body frame 51c. The first guided member and the second guided member are pin-shaped members that extend laterally inward of the machine body 100.
