Front portion58is provided such that a lateral distance L from centerline101of operator's seat41to front portion58in a top view increases from the rear toward the front. In the top view, front portion58extends diagonally with respect to the fore/aft direction. Seat cushion43has a front end located lateral to front portion58.

A direction of slide of control levers53mand53nis set to a diagonal direction with respect to the fore/aft direction, in correspondence with inclination of front portion58. An angle formed between the direction of slide of control levers53mand53nand the fore/aft direction (centerline101of operator's seat41) is within a range, for example, not smaller than 5° and not greater than 15°.

As shown inFIGS.2to5, wheel loader10further includes armrest61. Armrest61is provided lateral to operator's seat41. Armrest61is provided on the right side of operator's seat41.

Armrest61is used as a support for an operator's elbow. Armrest61is provided above console51(housing portion52). Armrest61is provided at a position where at least a part of armrest61is projected on upper surface54of housing portion52in the top view. Armrest61is provided in the rear of operation portion53(control levers53mand53n). Armrest61is provided at a position distant rearward from operation portion53.

Armrest61includes an upper surface63. Upper surface63is provided in parallel to the horizontal direction. Upper surface63serves as an elbow support surface on which the elbow of the operator is placed. Upper surface63is located above seat cushion43. Upper surface63is located above upper surface54of housing portion52. Upper surface63is in such an elongated shape that the fore/aft direction is defined as the longitudinal direction and the lateral direction is defined as the short-side direction. Upper surface63is in such a substantially rectangular shape that the fore/aft direction is defined as the longitudinal direction and the lateral direction is defined as the short-side direction.

Upper surface63includes a front end63fand a rear end63r. Front end63fis located at the front end of upper surface63. Among four sides of upper surface63in the substantially rectangular shape, front end63fcorresponds to a short side located on a front side. Rear end63ris located at the rear end of upper surface63. Among the four sides of upper surface63in the substantially rectangular shape, rear end63rcorresponds to a short side located on a rear side.

As shown inFIG.2, front end63fis located lateral to seat cushion43in the top view. Rear end63ris located lateral to seat back42in the top view.

FIG.6is a top view showing an operation of the armrest. As shown inFIGS.3and6, armrest61operates independently of console51such that rear end63rof upper surface63is laterally displaced in the top view. Armrest61can operate such that rear end63rof upper surface63is laterally displaced in the top view while console51is resting.

Armrest61pivots around a pivot central axis102. Pivot central axis102intersects with upper surface63. Pivot central axis102is orthogonal to upper surface63. Pivot central axis102is a virtual straight line that extends in a vertical direction.

Pivot central axis102is located between rear end63rof upper surface63and front end63fof upper surface63in the fore/aft direction. Pivot central axis102is located closer to front end63fof upper surface63than to rear end63rof upper surface63in the fore/aft direction. A length between pivot central axis102and front end63fof upper surface63in the fore/aft direction is shorter than a length between pivot central axis102and rear end63rof upper surface63in the fore/aft direction.

As armrest61pivots within a prescribed range of angles around pivot central axis102in such a construction, rear end63rof upper surface63is laterally displaced. Rear end63rof upper surface63is laterally displaced along an arc around pivot central axis102.

FIG.6shows with a solid line, armrest61(61L) at the time when rear end63rof upper surface63is displaced to a leftmost position and shows with a chain double dotted line, armrest61(61R) at the time when rear end63rof upper surface63is displaced to a rightmost position. A range of angles within which armrest61can pivot may be, for example, not smaller than 3° and not greater than 20° or not smaller than 6° and not greater than 10°.

FIG.7is a top view showing a seated state of the operator. As shown inFIG.7, an operator who sits in operator's seat41operates operation portion53(control levers53mand53n) in a general operation posture with his/her elbow being placed on upper surface63of armrest61. At this time, the operator's elbow is placed at a position closer toward the rear of upper surface63and the operator's arm extends forward from the rear side of upper surface63toward operation portion53.

In wheel loader10, armrest61operates such that rear end63rof upper surface63is laterally displaced in the top view. According to such a construction, when the operator uses armrest61as the elbow support, the operator can take a comfortable operation posture regardless of his/her physical build.

More specifically, when the operator has a large shoulder width, the operator should only operate armrest61such that rear end63rof upper surface63is displaced to the right (armrest61R inFIG.6). The operator can thus operate operation portion53with his/her elbow being placed on upper surface63of armrest61without taking such an uncomfortable posture as shrugging his/her shoulder. When the operator has a small shoulder width, the operator should only operate armrest61such that rear end63rof upper surface63is displaced to the left (armrest61L inFIG.6). The operator can thus operate operation portion53with his/her elbow being placed on upper surface63of armrest61without extremely squaring his/her elbow.

Armrest61pivots around pivot central axis102. According to such a construction, an operation mechanism of armrest61can be constructed in a more simplified manner than in an example where the entire armrest61performs a slide operation in the lateral direction.

Pivot central axis102is located closer to front end63fof upper surface63than to rear end63rof upper surface63in the fore/aft direction.

According to such a construction, when armrest61pivots, a length of lateral displacement of rear end63ris longer than a length of lateral displacement of front end63f. A larger range within which the position of rear end63ris adjusted can thus be set. In contrast, when armrest61pivots, a length of lateral displacement of front end63fis shorter than a length of lateral displacement of rear end63r. Loss of relative positional relation between operation portion53and a position of the hand of the operator who operates operation portion53with adjustment of the position of rear end63rin the lateral direction can thus be suppressed.

Front portion58of console51is provided such that lateral distance L from centerline101of operator's seat41to front portion58increases from the rear toward the front in the top view. According to such a construction, a wide space can be secured between the leg (mainly the knee) of the operator who sits in operator's seat41and console51. Even though the operator is of large build, the operator can thus take a comfortable operation posture.

Pivot central axis102of armrest61may be defined as a straight line extending diagonally with respect to the vertical direction. For example, when upper surface63of armrest61is inclined at a prescribed angle with respect to the horizontal direction such that a right end side thereof is lower than a left end side, pivot central axis102may be defined as a straight line inclined at the prescribed angle with respect to the vertical direction, in correspondence with inclination of upper surface63. Pivot central axis102is not limited to be arranged at a position closer to front end63fof upper surface63but may be provided, for example, at a position at the center between front end63fof upper surface63and rear end63rof upper surface63in the fore/aft direction.

The operation of armrest61is not limited to the pivoting operation, but for example, the entire armrest61may perform a slide operation in the lateral direction.

In succession, a more specific structure of armrest61will be described.FIG.8is a top view showing the armrest seen through the upper surface of the armrest inFIG.7.FIG.9is a cross-sectional view of the armrest when viewed in a direction shown with an arrow IX-IX inFIG.8.FIG.10is an exploded view showing the armrest.

As shown inFIGS.8to10, armrest61includes a cushion portion62, a boss portion66, a bracket71, a collar91, and a bolt86.

Cushion portion62includes upper surface63and a lower surface64. Cushion portion62is in a shape of a flat plate for which a direction (the upward/downward direction) of connection of upper surface63and lower surface64to each other is defined as a direction of thickness. Cushion portion62is formed of an elastic cushion material. Cushion portion62is formed, for example, of a urethane foam. Cushion portion62contains a metal plate96(seeFIG.9). Plate96is provided in parallel to the horizontal direction.

Boss portion66protrudes downward from cushion portion62along pivot central axis102. Boss portion66is in a shape of a shaft that protrudes from lower surface64along pivot central axis102. Boss portion66is fixed to plate96in cushion portion62. A female thread67is provided in boss portion66. Female thread67is provided along pivot central axis102.

Bracket71is provided below cushion portion62. Bracket71is attached to cushion portion62.

Bracket71includes a lateral plate portion72and a vertical plate portion77. Lateral plate portion72is in a shape of a flat plate and provided in parallel to the horizontal direction. In the top view, lateral plate portion72is in such an elongated shape that the fore/aft direction is defined as the longitudinal direction and the lateral direction is defined as the short-side direction in the top view. Lateral plate portion72is smaller in area in the top view than cushion portion62(upper surface63). Vertical plate portion77is provided at a position where a side end of lateral plate portion72is bent. Vertical plate portion77is in a shape of a flat plate and provided in parallel to the vertical direction. Vertical plate portion77is provided along the fore/aft direction.

Bracket71further includes a boss fitting portion73. Boss fitting portion73is provided in lateral plate portion72. Boss fitting portion73protrudes downward from lateral plate portion72. Boss fitting portion73is provided with hole74. Hole74is provided as a through hole that passes through boss fitting portion73in the upward/downward direction. Hole74is larger in diameter than boss portion66. Boss fitting portion73is in a shape of a cylinder that extends along the upward/downward direction.

Lateral plate portion72is provided below cushion portion62. Lateral plate portion72bears a weight of cushion portion62. Lower surface64of cushion portion62is opposed to lateral plate portion72with a gap lying therebetween in the upward/downward direction. Lateral plate portion72is arranged inside an area where upper surface63of cushion portion62is projected below. Boss portion66is fitted into hole74provided in boss fitting portion73.

Collar91is in a cylindrical shape. Collar91is interposed between boss portion66and boss fitting portion73in a direction of radius of pivot central axis102. Collar91is in slide contact with an outer circumferential surface of boss portion66and an inner circumferential surface of boss fitting portion73that defines hole74. Boss portion66is fitted into hole74provided in boss fitting portion73with collar91being interposed. Collar91is formed, for example, of a resin excellent in slidability.

Collar91includes a flange93. Flange93spreads radially outward like a brim from an upper end of collar91in an axial direction of pivot central axis102. Flange93is interposed between lateral plate portion72and boss portion66in the axial direction of pivot central axis102. According to such a construction, boss portion66is provided without being in contact with bracket71.

Bolt86is screwed from below into female thread67provided in boss portion66. Boss fitting portion73is held by bolt86as being integrated with boss portion66.

As boss portion66is fitted into hole74provided in boss fitting portion73, cushion portion62is supported as being pivotable around pivot central axis102. In this case, boss portion66protruding from cushion portion62along pivot central axis102is constrained by boss fitting portion73over a prescribed range in the axial direction of pivot central axis102. Since cushion portion62can thus more reliably be supported, wobbling of cushion portion62at the time of pivot of armrest61can be prevented.

As collar91is provided, boss portion66is provided without being in contact with bracket71. According to such a construction, slide resistance produced at the time of pivot of armrest61can be suppressed.

Armrest61further includes a fastened member68and a lateral arrangement adjustment knob87. Fastened member68protrudes downward from cushion portion62(lower surface64). A length of protrusion of fastened member68from cushion portion62(lower surface64) is shorter than a length of protrusion of boss portion66from cushion portion62(lower surface64). Fastened member68is fixed to plate96in cushion portion62. A female thread69is provided in fastened member68. Female thread69is provided along the upward/downward direction.

Fastened member68is located between rear end63rof upper surface63and front end63fof upper surface63in the fore/aft direction. Fastened member68is provided in the rear of pivot central axis102. Fastened member68is located closer to rear end63rof upper surface63than to front end63fof upper surface63in the fore/aft direction. A length between fastened member68and rear end63rof upper surface63in the fore/aft direction is shorter than a length between fastened member68and front end63fof upper surface63in the fore/aft direction.

An elongated hole75is provided in bracket71. Elongated hole75is provided to pass through lateral plate portion72in a direction of thickness thereof. Elongated hole75is in a shape of an elongated hole that extends laterally while it maintains a constant width in the fore/aft direction. Elongated hole75extends like an arc around pivot central axis102.

Lateral arrangement adjustment knob87is inserted from below into elongated hole75provided in bracket71and further screwed into female thread69provided in fastened member68. While lateral arrangement adjustment knob87is unfastened, cushion portion62can pivot around pivot central axis102. A position of cushion portion62can thus laterally be adjustable. While lateral arrangement adjustment knob87is tightened around fastened member68, a pivot operation by cushion portion62is restricted. The adjusted position of cushion portion62in the lateral direction is thus fixed.

Boss portion66(pivot central axis102) is provided closer to front end63fof upper surface63in the fore/aft direction, whereas fastened member68is provided closer to rear end63rof upper surface63in the fore/aft direction. According to such a construction, positions of two points where cushion portion62is supported by bracket71can greatly be distant from each other in the fore/aft direction. Therefore, cushion portion62can be supported in a more stable manner.

In succession, a support structure for console51and armrest61will be described.FIG.11is a perspective view showing a support structure for the console and the armrest.FIG.12is an exploded view showing the support structure for the console and the armrest.

Intermediate bracket81includes a base end portion85, an extending portion82, a tip end portion83, and a rack portion84.

Base end portion85is in a shape of a flat plate and provided in parallel to the horizontal direction. Base end portion85is fastened to support plate45. Extending portion82extends diagonally upward from base end portion85toward tip end portion83. Extending portion82is provided as being laterally away from operator's seat41from base end portion85toward tip end portion83. Tip end portion83is in a shape of a flat plate and provided in parallel to the horizontal direction. Console51is placed on tip end portion83. Console51is supported on tip end portion83as being slidable in the fore/aft direction.

Rack portion84is provided at tip end portion83. Rack portion84is constructed of teeth aligned along the fore/aft direction. Console51is provided with locking pins (not shown) to be engaged with rack portion84. As the operator operates a fore/aft arrangement adjustment lever (not shown), the locking pins are released from rack portion84. Positions of console51and armrest61attached to console51can thus be adjusted in the fore/aft direction.

As shown inFIGS.10to12, bracket71is provided with a height adjustment groove78(78F and78R). Height adjustment groove78F and height adjustment groove78R are provided at a distance from each other in the fore/aft direction. Height adjustment groove78is provided to pass through vertical plate portion77in a direction of thickness thereof.

Height adjustment groove78includes a vertical groove79and a plurality of diagonal grooves80. Vertical groove79extends linearly along the upward/downward direction. Diagonal groove80extends diagonally upward from vertical groove79. The plurality of diagonal grooves80are provided at a distance from each other in the upward/downward direction. The plurality of diagonal grooves80are provided at regular intervals.

Console51further includes an attachment angle56. Attachment angle56is provided in the rear of operation portion53. Attachment angle56is provided with a plurality of female threads57. The plurality of female threads57are provided at a distance from each other in the fore/aft direction, in conformity with a pitch between height adjustment groove78F and height adjustment groove78R.

Armrest61further includes a height adjustment knob88(88F and88R). Bracket71(vertical plate portion77) is superimposed on attachment angle56sideways. Height adjustment knob88F is inserted sideways into height adjustment groove78F (diagonal groove80) provided in bracket71and further screwed into female thread57provided in attachment angle56. Height adjustment knob88R is inserted in height adjustment groove78R (diagonal groove80) provided in bracket71and further screwed into female thread57provided in attachment angle56. Armrest61is thus fastened to console51.

While height adjustment knob88is unfastened, height adjustment knob88can move among the plurality of diagonal grooves80through vertical groove79. A height of armrest61(upper surface63) can thus be adjusted. By inserting height adjustment knobs88into diagonal grooves80different in height between height adjustment groove78F and height adjustment groove78R, inclination of armrest61in the upward/downward direction can also be adjusted. While height adjustment knob88is fastened to attachment angle56, movement of height adjustment knob88in height adjustment groove78is restricted. The adjusted height and inclination of armrest61in the upward/downward direction are thus fixed.

In wheel loader10, the position of console51and armrest61in the fore/aft direction can be adjusted or the height of armrest61and inclination of armrest61in the upward/downward direction can be adjusted in conformity with physical build of the operator. The operator can thus take a further comfortable operation posture.

FIGS.13to18are side views showing various forms of use of the console and the armrest.

InFIG.13, the height of armrest61is adjusted to an intermediate level. In FIG.14, the height of armrest61is adjusted to a low level. InFIG.15, the height of armrest61is adjusted to a high level.

InFIG.16, console51is held in a horizontal posture whereas armrest61is adjusted to a lean forward posture (such a posture that the front end is located below the rear end). InFIG.17, armrest61is held in the horizontal posture whereas console51is adjusted to a lean rearward posture (such a posture that the rear end is located below the front end). InFIG.18, armrest61is held in the horizontal posture whereas console51is adjusted to the lean forward posture.

A construction and an effect of wheel loader10in the present embodiment will be summarized and described below.

Wheel loader10as the work vehicle includes operator's seat41, console51, and armrest61. Console51includes operation portion53. Console51is provided lateral to operator's seat41. Armrest61includes upper surface63. Armrest61is provided lateral to operator's seat41and in the rear of operation portion53. Armrest61operates independently of console51such that rear end63rof upper surface63is laterally displaced in the top view.

According to such a construction, the position of rear end63rof upper surface63can laterally be adjusted in conformity with physical build of the operator. The operator can thus take a comfortable operation posture.

Armrest61pivots around pivot central axis102that intersects with upper surface63. According to such a construction, armrest61that operates such that rear end63rof upper surface63is laterally displaced in the top view can be realized with a simplified construction.

Pivot central axis102is located closer to front end63fof upper surface63than to rear end63rof upper surface63in the fore/aft direction.

Since the length of lateral displacement of rear end63ris longer than the length of lateral displacement of front end63faccording to such a construction, a larger range within which the position of rear end63ris adjusted can be set. Since the length of lateral displacement of front end63fis shorter than the length of lateral displacement of rear end63r, loss of relative positional relation between operation portion53and a position of the hand of the operator who operates operation portion53with adjustment of the position of rear end63rcan be suppressed.

According to such a construction, boss portion66protruding from cushion portion62along pivot central axis102is constrained by boss fitting portion73over a prescribed range in the axial direction of pivot central axis102. Therefore, wobbling of cushion portion62at the time of pivot can be prevented.

Console61further includes front portion58. Front portion58is provided in front of armrest61. Front portion58is provided such that a lateral distance from centerline101of operator's seat41that extends in the fore/aft direction to front portion58increases from the rear toward the front in the top view.

According to such a construction, a wide space can be secured between the leg of the operator who sits in operator's seat41and console51. Even though the operator of large build, the operator can thus take a comfortable operation posture.

The present disclosure is applied to various work vehicles including an armrest, without being limited to the wheel loader.
