Summary of the Invention
Problems to be Solved by the Invention
[0004] Although a display device and a holding portion for a mobile terminal are required to be equipped even in a canopy-mounted working machine, in a canopy-mounted working machine, there is no existing member suitable for providing a display device, a mobile terminal holding portion, etc., such as an air delivery duct found in Patent Document 1, at a position in the front side of the driver's seat where it is easy for the operator sitting in the driver's seat to visually recognize. Also, if these are provided on the console on the side of the driver's seat, the operator who sits in the driver's seat and visually recognizes the state of the front working device has to greatly shift the line of sight to visually recognize the screen of the display device and the mobile terminal, and since it is close to the driver's seat, it may press the feet of the operator sitting in the driver's seat and make it difficult to perform pedal operations.
[0005] Therefore, in a canopy-mounted work machine, it is conceivable to install a new structure to support the display device and the holding member of the mobile terminal in a position where the operator sitting in the driver's seat can easily see the display information of the display device and the mobile terminal while also being able to see the status of the work machine. However, such a structure would require sufficient rigidity to support these, and if such a rigid structure were to be modified in a way that restricts the movement of the mobile terminal to prevent it from coming loose from the holding member, it would likely lead to increased costs.
[0006] The object of the present invention is to provide a work machine that can solve the above-mentioned problems. [Means for solving the problem]
[0007] A work machine according to one aspect of the present invention comprises a machine body, a driver's seat provided on the machine body, a display device disposed near the driver's seat, and a holding member capable of holding a mobile terminal while restricting its downward and horizontal movement, wherein the holding member is positioned below the display device, in a position facing the display device in the vertical direction, and the upward movement of the mobile terminal held by the holding member is restricted by the display device. [Effects of the Invention]
[0008] In the above-described work machine, the display device restricts the upward movement of the portable terminal, which cannot be fully restricted by the holding member. Therefore, the support member (columnar body) that supports the display device and the holding member does not need to undergo complex processing to restrict the movement of the portable terminal, such as forming a step. Furthermore, since the display device and the holding member can be positioned opposite each other in the vertical direction, the support member (columnar body) can be a simple shape, such as a long, nearly straight length. Consequently, even in cases where there are no existing members suitable for mounting the display device and holding member at the desired location, such as in a canopy-mounted work machine, and it is necessary to provide a new support member, the cost of adding the support member can be kept low.

[0010] The schematic configuration of the working machine 1 will be described with reference to FIGS. 1 to 3. FIG. 1 is a side view of the swing type excavation working machine 1 (hereinafter simply referred to as "working machine 1"). FIG. 2 is a plan view of the working machine 1. FIG. 3 is a plan view of the main part of the working machine 1 excluding the canopy 27 and the like.
[0011] In this embodiment, the direction of arrow A1 shown in FIGS. 1 to 3 is defined as the front direction, the direction of arrow A2 as the rear direction, the direction of arrow B1 shown in FIGS. 2 and 3 which is perpendicular to these arrows A1 and A2 as the left direction, and the direction of arrow B2 as the right direction.
[0012] The working machine 1 includes a traveling body 10, a machine body 20, and a working device 30. The machine body 20 is mounted on the upper part of the traveling body 10 (specifically, the traveling frame 11 described later) via a swivel shaft (swivel joint) having a vertical axis Xv shown in FIG. 1. The machine body 20 can rotate relative to the traveling body 10 horizontally (swing) about the axis Xv by a hydraulic swing motor (not shown).
[0013] The traveling body 10 has a traveling frame 11 and a pair of left and right traveling devices 12, and each traveling device 12 is driven by a hydraulic traveling motor (not shown). In addition, a dozer 13 is provided at the front of the traveling body 10. The dozer 13 has a blade 13a disposed in front of the pair of left and right traveling devices 12 and an actuator (hydraulic cylinder) 13b for swinging the blade 13a up and down.
[0014] The machine body 20 includes a platform (swing base) 21 whose center is connected to the traveling frame 11 via a swivel shaft (swivel joint), side covers 22 erected along the front edge and the left edge of the platform 21, a rear bonnet 24 erected along the rear edge of the platform 21, side bonnets 25 erected along the right edge of the platform 21, and the like.
[0015] The platform 21 is equipped with a prime mover (such as an engine), hydraulic equipment such as a hydraulic pump, a battery, tanks such as a fuel tank and a hydraulic oil tank, etc., and is covered by a rear bonnet 24, side bonnets 25, etc.
[0016] The airframe 20 has a driver's seat 26 immediately in front of the rear bonnet 24 and to the left of the side bonnet 25. In front of and to the sides of the driver's seat 26, at a position corresponding to the upper edge of the side cover 22, a lower floor part 21a supported via a support member (not shown) on the platform 21 is provided. Also, in front of the driver's seat 26, on the lower floor part 21a, a floor covering 23 such as a mat made of, for example, rubber (natural rubber, urethane rubber) or synthetic resin is laid.
[0017] Thus, the airframe 20 is provided with a floor body 20f consisting of the lower floor part 21a and the floor covering 23 laid on the lower floor part 21a in front of the driver's seat 26. Note that the floor body 20f may consist only of the lower floor part 21a on which the floor covering 23 is not laid.
[0018] Also, the lower floor part 21a may be, for example, made of a plate-like material horizontally spanned so as to cover all or part of the horizontal direction of the floor body 20f, or made of a combination of long frame materials extending in the horizontal direction (such as the front-back direction and / or the left-right direction), or a combination of such plate-like materials and frames, etc.
[0019] Above the rear bonnet 24, a canopy 27 that covers the driver's seat 26 from above is erected. Also, on the left side of the side bonnet 25 facing the right part of the driver's seat 26, a console 25a incorporating a drink holder, a cigarette socket, etc. is arranged. [[ID= The working device 30 includes a boom 31, an arm 32 pivotally supported at the tip of the boom 31, and a bucket 33 pivotally supported at the tip of the arm 32. Since the base end of the boom 31 is pivotally supported by the swing bracket 14, the entire working device 30, including the boom 31, arm 32, and bucket 33, can rotate (oscillate) horizontally relative to the machine body 20 together with the swing bracket 14.
[0022] Furthermore, the work device 30 is equipped with a boom cylinder 34, an arm cylinder 35, and a bucket cylinder 36, which are hydraulic actuators for driving (swinging) the boom 31, arm 32, and bucket 33. In addition, the machine body 20 (platform 21) is supported by a swing cylinder 39, which is a hydraulic actuator for rotating (swinging) the swing bracket 14 relative to the machine body 20 (base 29).
[0023] In the machine body 20, a pair of left and right work operation levers 61 are provided at the left front end and right front end of the driver's seat 26 to control the extension of the boom cylinder 34, arm cylinder 35, and bucket cylinder 36 for the rotation (oscillation) of the boom 31, arm 32, and bucket 33 of the work device 30. Also, a pair of left and right travel operation levers 62 are provided in front of the left and right center of the driver's seat 26, above the upper floor material 23 (floor body 20f), to control the rotation speed and rotation direction of the hydraulic travel motors provided on each of the left and right travel devices 12. A pair of left and right travel pedals 63 are separately provided at the feet of the pair of left and right travel operation levers 62.
[0024] Furthermore, as shown in Figure 3, a pair of through holes 23a are provided on the left and right outer sides of the pair of left and right travel operation levers 62 in the upper floor material (mat) 23 of the floor body 20f, which are formed to penetrate vertically. A pair of left and right pedals 64 are provided on the upper floor material 23 (floor body 20f), corresponding to the pair of left and right through holes 23a. Each pedal 64 is pivotally supported by a support member provided on the lower floor portion 21a so as to pass through each through hole 23a, and its front and / or rear ends swing when the worker's foot is pressed down on each pedal 64.
[0025] For example, one of the pair of pedals 64 (for example, the right pedal 64) is a swing pedal 64 for controlling the extension of the swing cylinder 39 for the rotation (rocking) of the swing bracket 14, and the other (for example, the left pedal 64) is an AUX pedal 64 for controlling the flow rate and direction of the hydraulic fluid supplied to the AUX port provided on the work device 30 (a port for supplying hydraulic fluid to a hydraulic actuator provided on an AUX (reserve) attachment mounted on the work device 30 in place of (or in addition to) the bucket 33).
[0026] Preferably, one of the pair of left and right pedals 64 (the right pedal 64 in this embodiment) is positioned behind and / or to the side of the footrest of the columnar body 42 described later. Note that the pedals 64 other than the driving pedal 63 may be just one, for example, positioned behind and / or to the side of the footrest of the columnar body 42 described later, or there may be three or more.
[0027] Next, the configuration of the handrail 41 and columnar body 42 provided at the front of the floor body 20f will be explained with reference to Figures 1 to 10. Figure 4 is a front perspective view of the floor body 20f (upper floor material 23) equipped with the handrail 41 and columnar body 42, showing the display device 50 and terminal holder 45 (holding the mobile terminal 55) attached to the columnar body 42. Figure 5 is a side view of the floor body 20f equipped with the handrail 41 and columnar body 42, showing the display device 50 and terminal holder 45 (holding the mobile terminal 55) attached to the columnar body 42. Figure 6 is a side view of the main part of the columnar body 42 equipped with the display device 50 and terminal holder 45 (holding the mobile terminal 55).
[0028] Figure 7 is a front perspective view of the main part of the floor body 20f (upper floor material 23) equipped with a handrail 41 and columnar body 42, and shows a terminal holder 45 (holding a mobile terminal 55) attached to the columnar body 42 (display device 50 excluded). Figure 8 is a rear perspective view of the floor body 20f (upper floor material 23) equipped with a handrail 41 and columnar body 42, and shows a terminal holder 45 (not holding a mobile terminal 55) attached to the columnar body 42 (display device 50 excluded). Figure 9 is a plan view of the main part of the floor body 20f (upper floor material 23) equipped with a columnar body 42 (handrail 41 and display device 50 excluded), and shows a harness H arranged inside the columnar body 42 and a terminal holder 45 (holding a mobile terminal 55) attached to the columnar body 42. Figure 10 is a rear perspective view of the main part of the floor body 20f (upper floor material 23) equipped with a handrail 41 and a columnar body 42, (excluding the display device 50 and terminal holder 45) and shows the harness H routed within the columnar body 42 and the cover member 43 separated from the columnar body 42.
[0029] As shown in Figure 3, etc., a handrail 41 is provided in front of the aforementioned pair of left and right driving levers 62, driving pedal 63, and pedal 64, extending horizontally from left to right along the front end of the floor body 20f (upper floor material 23). As shown in Figures 4, 5, 8, etc., the handrail 41 bends downward at its left end, forming a column portion 41a that extends downward to the floor body 20f (upper floor material 23). To the right of the upper and lower part of the column portion 41a, an auxiliary rod portion 41b is provided below the handrail 41, extending parallel to the handrail 41.
[0030] The handrail 41, including the column portion 41a and the auxiliary rod portion 41b, is made of, for example, a pipe-shaped (hollow) or solid metal rod. In this embodiment, a single metal rod is bent to form the handrail 41 The column portion 41a is formed by the auxiliary rod portion 41b, which is a separate metal rod from the handrail 41 and column portion 41a and is connected to the column portion 41a by welding or the like. However, the method of forming and combining the handrail 41, column portion 41a and auxiliary rod portion 41b is not limited to this and other embodiments are also possible.
[0031] Furthermore, the combination of the handrail 41, column 41a, and auxiliary rod 41b also serves as a protective member to protect the equipment mounted on the aircraft 20 and the workers riding on the aircraft 20. It is sufficient for the member to have the strength required of a handrail or protective member, and as long as it has that strength, it may be made of a material other than metal, such as synthetic resin.
[0032] As shown in Figures 4, 5, and 8, a long columnar body 42 is erected at a position opposite the column 41a in the left-right direction, extending upward from the floor body 20f (upper floor material 23). As shown in Figures 9 and 10, the columnar body 42 is a trough-shaped plate material with a U-shaped cross-section that opens toward the rear driver's seat 26 in a plan view, and has a front plate portion 42a facing forward, and left and right side plate portions 42b that extend rearward from both the left and right ends of the front plate portion 42a and face to the left and right. That is, the columnar body 42 has a rectangular recess 42c that is surrounded on three sides by the front plate portion 42a and the left and right side plate portions 42b, with the rear surface being an open surface, and extends in the vertical direction, which is the longitudinal direction.
[0033] The columnar body 42 is made of, for example, a metal plate bent into a U-shape in cross-section. The columnar body 42 may also be, for example, a halved cylindrical member, and the shape of the recess 42c may correspond to that. Furthermore, the columnar body 42 only needs to have the strength to serve as a support for the display device 50 as described later, and as long as it has such strength, it may be made of a material other than metal, such as synthetic resin.
[0034] As shown in Figures 4, 5, and 7, the right end of the handrail 41 and the auxiliary rod 41b are connected to such a columnar body 42. The handrail 41 and the auxiliary rod 41b may be fixed to the columnar body 42 in a way that makes them irremovable by welding or the like, they may be integrally molded with the columnar body 42, or they may be detachably connected to the columnar body 42 with bolts or the like.
[0035] As shown in Figure 9, the rear surface of the opening of the recess 42c of the columnar body 42 is covered by a cover member 43 attached to the columnar body 42, thereby concealing the harness H inside the recess 42c of the columnar body 42 from the worker sitting in the driver's seat 26. Conversely, as shown in Figure 10, by removing the cover member 43 from the columnar body 42, the worker can see inside the recess 42c of the columnar body 42, and can also access the recess 42c to route the harness H into the recess 42c and to remove the harness H from the recess 42c.
[0036] In this embodiment, the cover member 43 is made of a plate material that is bent into a U shape in plan view cross-section and opens forward on the side opposite to the driver's seat 26. That is, the cover member 43 has a rear plate portion 43a that faces rearward, and left and right side plate portions 43b that extend forward from both the left and right ends of the rear plate portion 43a and face left and right sides.
[0037] The cover member 43 is attached to the columnar body 42 such that the left and right side plate portions 43b are aligned with the left and right side plate portions 42b of the columnar body 42, and the rear plate portion 43a covers the rear opening of the recess 42c of the columnar body 42. However, the cover member 43 only needs to be attached to the columnar body 42 in a way that covers the rear opening of the recess 42c, and may, for example, be a flat plate having an area sufficient to cover the rear opening of the recess 42c (i.e., consisting only of the rear plate portion 43a, omitting the left and right side plate portions 43b).
[0038] The cover member 43 may be made of synthetic resin material, metal plate material, etc., but the columnar body 42 It may be made of any material that is suitable for protecting the harness H in the recess 42c when it is attached to the mounting.
[0039] Furthermore, it is preferable that the cover member 43 be detachably attached to the columnar body 42 so that it can be removed during maintenance work, and the raw materials are also preferably appropriate to the manner in which it is attached to the columnar body 42.
[0040] In this embodiment, the cover member 43 is constructed by molding an elastic material such as rubber into a U-shape in cross-section. As shown in Figures 7 and 9, each of the left and right side plate portions 43b has a claw portion 43c that protrudes in a direction that brings the left and right side plate portions 43b closer together. On the other hand, as shown in Figures 7 and 10, one or more holes 42d corresponding to each claw portion 43c of the cover member 43 are formed in the left and right side plate portions 42b of the columnar body 42. Note that the holes 42d may be notches or recesses.
[0041] As shown in Figures 7 and 9, the left and right side plate portions 43b of the cover member 43 abut against the left and right side plate portions 42b of the columnar body 42, and the claw portions 43c of the cover member 43 fit into the holes 42d of the columnar body 42, thereby completing the attachment of the cover member 43 to the columnar body 42.
[0042] Furthermore, when attaching the cover member 43 to the columnar body 42, before each claw portion 43c is fitted into each hole 42d, for example, if the cover member 43 is moved from the rear to the front of the columnar body 42 with the left and right side plate portions 43b placed against the outside of the left and right side plate portions 42b, the claw portions 43c will slide on the left and right side plate portions 42b during this movement, eventually reaching the holes 42d, and the elastic force (biasing force) will cause each claw portion 43c to naturally fit into the holes 42d.
[0043] On the other hand, in order to remove the cover member 43 from the columnar body 42 for maintenance work, etc., by slightly spreading the left and right side plate portions 43b of the cover member 43 against the elastic force (biasing force), the claw portion 43c can be easily removed from the hole 42d and the cover member 43 can be removed from the columnar body 42.
[0044] For example, if the cover member 43 is made of a metal plate or plastic with a U-shaped cross-section and not very elastic, the left and right side plate portions 43b of the cover member may be fastened to the left and right side plate portions 42b of the columnar body 42 which also has a U-shaped cross-section using bolts, nuts, screws, etc.
[0045] As described above, the harness H is routed inside the columnar body 42, and the cover member 43 is attached to cover the inside. As shown in Figures 4 to 6, the display device 50 and the terminal holder 45 are attached to the rear side of the columnar body 42.
[0046] In this embodiment of the work machine 1, as can be seen in Figures 1 to 3, the columnar body 42 in front of the driver's seat 26, the display device 50 and terminal holder 45 supported by it are positioned to the right of the driver's seat 26 in the left-right direction. Therefore, the screen display section 52 at the rear end of the display device 50 and the (rear) display screen of the portable terminal 55 held by the terminal holder 45 are positioned at a slight leftward angle so as to face the line of sight of the worker sitting in the driver's seat 26. In response to this, the columnar body 42 (and cover member 43) is a long, straight length from the bottom end to the top end in the vertical direction, while the rear surface, which is the side to which the display device 50 and terminal holder 45 are attached, is tilted slightly to the left. The left end is positioned towards the front and the right end towards the rear, creating a slight inclination on both sides.
[0047] Furthermore, the handrail 41 (and auxiliary rod 41b) is not in a straight line from the left end on the column 41a side to the right end on the columnar body 42 side. Rather, the portion from the middle of the left-right direction to the right end corresponds to the inclination of the columnar body 42 to which it is connected at the right end, and is approximately the same as the inclination angle of the columnar body 42. It extends diagonally to the right and rear at an angle.
[0048] Therefore, in the following descriptions of the handrail 41, columnar body 42 (cover member 43), display device 50 (main body 51, screen display unit 52), terminal holder 45 (protective member 46), and the mobile terminal 55 held by the terminal holder 45, the front, back, left, and right positions and directions are frequently mentioned. However, these do not strictly correspond to the directions and positions indicated by arrows A1, A2, B1, and B2 shown in Figures 1 to 3, but rather roughly correspond, taking into account the inclination state of the columnar body 42, etc., as described above.
[0049] As shown in Figures 4 to 6, the display device 50 is attached to the upper end of the columnar body 42 via a stay 44 having the configuration shown in Figure 8. The display device 50 consists of a main body 51 housing a controller and the like, and a panel-shaped screen display unit 52 provided at the rear end of the main body 51 (on the driver's seat 26 side).
[0050] The front end surface 51c of the main body 51 is attached to the stay 44. As shown in Figure 6, the front end surface 51c of the main body 51 and the rear end surface on the opposite side are approximately parallel, and therefore the screen display unit 52 provided on the rear end surface and the front end surface 51c of the main body 51 are approximately parallel.
[0051] As shown in Figure 8, etc., in this embodiment, the rear surface (mounting surface) of the stay 44 on the display device 50 side is a sloped surface that inclines forward upward (rear downward), and as shown in Figure 6, the front end surface 51c that is attached to this surface is also a sloped surface that inclines forward upward (rear downward).
[0052] The mounting surface of the stay 44 may, for example, be a vertical surface (or it may be replaced with such a stay), and by mounting it to such a vertical surface, it is possible to make the front end surface 51c of the main body 51 of the display device 50 a vertical surface. Alternatively, the inclination of the mounting surface of the stay 44 may be closer to horizontal (or it may be replaced with such a stay), and by mounting it to such a surface, it is possible to make the inclination angle of the front end surface 51c of the main body 51 of the display device 50 from the horizontal direction smaller.
[0053] As shown in Figure 6, the lower surface of the main body 51 is formed as a rear lower surface 51a that extends forward from the lower end of the rear end surface of the main body 51 on which the screen display unit 52 is provided, and a front lower surface 51b that extends between the lower end of the front end surface 51c and the front end of the rear lower surface 51a on the front side of the rear lower surface 51a.
[0054] Here, at the lower part of the main body 51 of the display device 50, the slope that inclines downward (inclined forward downward (rear upward)) as it approaches the front opposite to the driver's seat 26 will be referred to as the first slope. On the other hand, the slope that extends from the front side of the first slope opposite to the driver's seat 26 and inclines upward (inclined forward upward (rear downward)) as it approaches the front opposite to the driver's seat 26 will be referred to as the second slope.
[0055] As shown in Figure 6, in the display device 50 attached to the upper part of the columnar body 42 via a stay 44, with the front end surface 51c being a sloped surface that inclines forward upward (rear downward), the rear lower surface 51a is a first slope that inclines downward (inclines forward downward (rear upward)) from the lower end of the rear end surface of the main body 51 on which the screen display unit 52 is provided, toward the front opposite to the driver's seat 26. That is, the rear lower surface 51a inclines downward from the lower end of the screen display unit 52 toward the vicinity of the upper end of the portable terminal 55, which is held by the terminal holder 45 at a position below the display device 50 and further forward and toward the front opposite to the driver's seat 26, as will be described later.
[0056] As mentioned above, the mounting surface of the stay 44 (and the display device to be attached to said mounting surface) The inclination angle of the rear lower surface 51a can be changed by changing the inclination angle of the front end surface 51c) of the main body 51 of 50. For example, by mounting the display device 50 to the stay 44 having a mounting surface such that the front end surface 51c and the screen of the screen display unit 52 are on a vertical plane, the inclination angle of the rear lower surface 51a can be reduced, making the rear lower surface 51a a gently sloping first slope (sloping in a forward downward (rear upward) direction) or a horizontal plane.
[0057] When the display device 50 is attached to the upper part of the columnar body 42 via a stay 44 having an inclined mounting surface, as shown in Figure 6, the front end surface 51c is positioned above the front of the upper end of the portable terminal 55 held by the terminal holder 45, as a second inclined surface that slopes forward and upward (rear and downward). On the other hand, the front lower surface 51b is approximately horizontal and is positioned directly above the upper end of the portable terminal 55 held by the terminal holder 45, as will be described later.
[0058] Furthermore, if the display device 50 is mounted on the upper part of the columnar body 42 via a stay 44 having a vertical mounting surface instead of the stay 44 having an inclined mounting surface as shown in Figure 6, the front end surface 51c attached to the mounting surface becomes a vertical surface and is positioned in front of and above the upper end of the portable terminal 55 held by the terminal holder 45. On the other hand, the front lower surface 51b extending from the front side of the rear lower surface 51a becomes a second inclined surface that slopes in a forward-upward (rear-downward) direction and is positioned directly above the upper end of the portable terminal 55 held by the terminal holder 45.
[0059] Furthermore, the inclination angle of the mounting surface of the stay 44 is an angle between the inclination angle of the mounting surface of the stay 44 used in the embodiment shown in Figure 6 and the angle of the vertical plane, which is 90 degrees. When the display device 50 is mounted on the upper part of the columnar body 42 via such a stay 44, the front lower surface 51b, which extends from the front of the rear lower surface 51a, is positioned directly above the upper end of the portable terminal 55 held by the terminal holder 45 as a second inclined surface that inclins in a forward-upward (rear-downward) direction. In addition, the front end surface 51c attached to the mounting surface is also positioned above the front of the upper end of the portable terminal 55 held by the terminal holder 45 as a second inclined surface that inclins in a forward-upward (rear-downward) direction with a larger inclination angle than the front lower surface 51b.
[0060] Thus, depending on the setting of the mounting angle of the display device 50 to the columnar body 42, it is also possible to position the front lower surface 51b and the front end surface 51c as a second inclined surface in two stages, extending from directly above the portable terminal 55 held in the terminal holder 45 to the front and above, on the front side (opposite side from the driver's seat 26) of the rear lower surface 51a which serves as the first inclined surface.
[0061] Preferably, the display device 50 may be supported on the columnar body 42 in a manner that allows it to swing up and down relative to the columnar body 42. In this case, for example, a bracket provided on the upper end of the columnar body 42 and a bracket provided on the stay 44 may be pivotally connected via a horizontal axis pivot, allowing the mounting angle of the stay 44 to the columnar body 42 to be adjusted. Alternatively, a bracket provided on the stay 44 and a bracket provided on the front end of the main body 51 of the display device 50 may be pivotally connected via a horizontal axis pivot, allowing the mounting angle of the display device 50 to the stay 44 to be adjusted. Alternatively, the upper end of the columnar body 42 and the front end of the main body 51 of the display device 50 may be directly pivotally connected via a horizontal axis pivot without using the stay 44.
[0062] The harness (electric wire) H connected to the controller etc. inside the main body 51 of the display device 50 is routed so as to pass through a rear-opening recess 42c formed in the columnar body 42 having a U-shaped cross-section, as described above. At the upper end of the columnar body 42, the upper end surface of the recess 42c is open, and the harness H that has passed through the recess 42c is routed through this opening into the main body 51 and connected to the controller. Also, at the lower end of the columnar body 42, the lower end surface of the recess 42c is open, and the harness H routed below the floor body 20f (for example, in the internal space of the machine body 20 between the lower floor portion 21a made of plate-like material and the bottom plate portion of the platform 21) or along the floor body 20f (for example, along the frame material of the lower floor portion 21a made of long frame material) is routed through this opening into the recess 42c of the columnar body 42. Furthermore, the harness H is routed so as to pass through the recess 42c from the floor body 20f, extend through the upper end opening of the recess 42c into the space above the columnar body 42, and reach the display device 50.
[0063] The display device 50 may also be attached to the handrail 41 or to a column 41a or auxiliary rod 41b provided integrally with the handrail 41. In this case, the harness H that passes through the recess 42c of the columnar body 42 may extend from an opening provided in the columnar body 42 (such as the upper end or intermediate parts above or below) and be connected to the display device 50 attached to the handrail 41, etc.
[0064] Thus, a terminal holder (holding member) 45 capable of holding a mobile terminal 55 such as a smartphone can be attached to a columnar body 42 that has a configuration that allows a harness H connected to a display device 50 attached to the upper part of the columnar body 42 or to a handrail 41 to be routed internally.
[0065] The configuration of the terminal holder 45 will be described below with reference to Figures 4 to 12. Figure 11 is a side cross-sectional view of the terminal holder 45 in the state of holding the mobile terminal 55. Figure 12 is a perspective view of the terminal holder 45 and the protective member 46 separated from the terminal holder 45.
[0066] As shown in Figure 12 and other figures, the terminal holder 45 has a rectangular case portion 45a that corresponds to the shape of the lower half of a mobile terminal 55 such as a smartphone, an arm portion 45b that extends forward from the case portion 45a, and a mounting plate portion 45c that extends in one direction (to the right in this embodiment) from the front end of the arm portion 45b.
[0067] The terminal holder 45 is constructed, for example, by integral molding of a synthetic resin material or by combining metal plate materials by welding, including the case portion 45a, the arm portion 45b, and the mounting plate portion 45c. The terminal holder 45 can be made of any raw material, and is not particularly limited in shape or size, as long as it can reliably hold the mobile terminal 55 under some of the conditions described later.
[0068] As shown in Figures 7 to 9, Figure 12, etc., the terminal holder 45 has a notch 45d surrounded by a case portion 45a, an arm portion 45b, and a mounting plate portion 45c. As shown in Figures 7 to 9, etc., the terminal holder 45 is attached to the columnar body 42 with the columnar body 42 (equipped with a cover member 43) inserted through this notch 45d.
[0069] That is, when the terminal holder 45 is attached to the columnar body 42 (equipped with a cover member 43), as shown in Figures 6 to 9, the case portion 45a is positioned behind the columnar body 42 (and the cover member 43) (towards the driver's seat 26), the arm portion 45b is positioned to follow one side of the columnar body 42 (the left side in this embodiment), and the mounting plate portion 45c is positioned to follow the front of the columnar body 42.
[0070] Thus, the terminal holder 45 is substantially attached to the rear side of the columnar body 42, that is, to the driver's seat 26 side. In other words, the portable terminal 55 is held by the terminal holder 45 (case portion 45a) at the rear side of the columnar body 42, that is, to the driver's seat 26 side.
[0071] As shown in Figures 7 and 12, the mounting plate portion 45c is provided with one or more bolt holes 45e (two in this embodiment, one above and one below), while the front end surface of the columnar body 42 is provided with a stay plate portion 42e having one or more screw holes 42f (two in this embodiment, one above and one below). The bolt holes 45e are aligned with the screw holes 42f (see Figure 10) of the stay plate portion 42e, and the bolts 47 (see Figures 4 and 6) are inserted through the bolt holes 45e and screwed into the screw holes 42f of the stay plate portion 42e, thereby fastening the mounting plate portion 45c to the stay plate portion 42e, and thereby fixing the end holder 45 to the columnar body 42. On the other hand, by removing the bolts 47 from the stay plate portion 42e and the mounting plate portion 45c, the end holder 45 can be detached from the columnar body 42 and moved freely.
[0072] In this embodiment, the number of bolt holes 45e and screw holes 42f in the stay plate portion 42e are the same (two in this embodiment), and the position of the terminal holder 45 attached to the columnar body 42 in the vertical direction is fixed at one location where the bolt holes 45e in the mounting plate portion 45c and the screw holes 42f in the stay plate portion 42e are aligned. However, in another embodiment, the mounting position of the terminal holder 45 to the columnar body 42 may be changed in the vertical direction.
[0073] In this alternative embodiment, for example, the stay plate portion 42e of the columnar body 42 may be enlarged in the vertical direction, and the stay plate portion 42e may be provided with more screw holes than the bolt holes 45e of the mounting plate portion 45c in a row in the vertical direction, thereby setting multiple mounting positions for the terminal holder 45 on the columnar body 42 that differ in the vertical direction, and the mounting position may be selected by aligning the bolt holes 45e of the mounting plate portion 45c with any of these screw holes.
[0074] Alternatively, a vertical guide rail may be provided on the columnar body 42 (or cover member 43), and an engaging portion may be provided on the terminal holder 45 that slidably engages with the guide rail. By sliding the engaging portion along the guide rail, the relative position of the terminal holder 45 with respect to the columnar body 42 can be changed vertically. Alternatively, without a guide rail, the arm portion 45b or other surface of the terminal holder 45 may be directly in contact with the side surface of the columnar body 42 (or cover member 43), and the position of the terminal holder 45 may be changed vertically by sliding the terminal holder 45 along the columnar body 42 (or cover member 43) while the surface is in contact.
[0075] Furthermore, a locking mechanism may be provided on the terminal holder 45 and / or the columnar body 42 to fix (lock) the positioned terminal holder 45 to the columnar body 42 (or cover member 43). The locking mechanism may also be configured to release the locked state between the terminal holder 45 and the columnar body 42 (or cover member 43) once it has been set. In addition, a plurality of screw holes provided in a vertical row on the columnar body 42, and a bolt or the like screwed into a selected screw hole among the plurality of screw holes, can also serve as such a locking mechanism.
[0076] Alternatively, without providing such screw holes, a simple screw rod with a knob could be used as a locking mechanism to press a portion of the terminal holder 45 against the side surface of the columnar body 42 (or cover member 43). By rotating the knob, the force with which the screw rod presses the terminal holder 45 against the columnar body 42 (or cover member 43) can be increased or decreased, thereby enabling a switch between a locked state and an unlocked state of the terminal holder 45 against the columnar body 42 (or cover member 43).
[0077] As shown in Figures 11 and 12, the case portion 45a of the terminal holder 45 has an upwardly opening rectangular recess 45f formed therein, corresponding to the shape of the case portion 45a, and the protective member 46 is fitted into the recess 45f.
[0078] The protective member 46 is formed in the shape of a rectangular case with an overall upward opening, and when fitted into the recess 45f of the case portion 45a, its outer surface engages with the inner surface of the case portion 45a. The protective member 46 may be fixed to the case portion 45a or it may be detachably attached.
[0079] The protective member 46 has an upwardly opening rectangular recess 46a that corresponds to the shape and size of the lower part of the mobile terminal 55. The lower part of the mobile terminal 55 is inserted into this recess 46a and held in place by the protective member 46.
[0080] The protective member 46 directly contacts the lower end of the mobile terminal 55 inserted into the recess 46a at the bottom end surface of the recess 46a. In this way, the mobile terminal 55 and the terminal holder 45 come into indirect contact via the protective member 46. That is, the protective member 46 functions as a cushion (buffer) for the mobile terminal 55.
[0081] Therefore, the protective member 46 is required to possess both the flexibility necessary to function as a cushioning material and the rigidity necessary to stably hold the mobile terminal 55. The raw material for the protective member 46 can be anything that can satisfy these requirements, but typically urethane rubber is considered.
[0082] As described above, the recess 46a of the protective member 46 is provided in the terminal holder (holding member) 45 as an upwardly opening recess for holding the lower part of the mobile terminal 55 that is inserted from above.
[0083] It is preferable that the portable terminal 55 held in the recess 46a is protected so that it does not fall out of the terminal holder 45 even if it bounces up due to vibrations of the work machine 1 or the like, and the lower end of the portable terminal 55 moves above the bottom surface of the recess 46a.
[0084] Here, even if the portable terminal 55 held in the recess 46a of the terminal holder 45 bounces up due to vibrations of the work machine 1, etc., and its lower end moves above the bottom surface of the recess 46a, the amount of upward movement of the portable terminal 55 due to the bounce is limited to the distance between the upper end of the portable terminal 55 and the display device 50. In other words, the upward movement of the portable terminal 55 due to the bounce, etc., is limited to the point where its upper end hits the display device 50.
[0085] Therefore, in this embodiment, the depth D of the recess 46a (see Figures 6 and 11) is made greater (deeper) than the vertical distance C between the upper end of the mobile terminal 55, which is inserted into the recess 46a and held by the terminal holder 45, and the display device 50 located above it.
[0086] As a result, when the upper end of the mobile terminal 55 jumps up to the maximum height where it abuts the display device 50, the height of the lower end of the mobile terminal 55 remains within the depth D of the recess 42c. That is, at this time, the lower end of the mobile terminal 55 is located within the recess 42c below the upper opening of the recess 42c. By setting the depth D of the recess 46a of the terminal holder 45 and the distance C between the terminal holder 45 and the display device 41 in this way, the mobile terminal 55 is prevented from detaching (falling out) from the terminal holder 45 due to jumping up.
[0087] Furthermore, if the mobile terminal 55 held in the terminal holder 45 is changed to a model with a shorter vertical length, the distance between the upper end of the mobile terminal 55 held in the terminal holder 45 and the display device 50 may change, and this distance C may become longer than the depth D of the recess 42c, potentially causing the mobile terminal 55 to spring out of the terminal holder 45.
[0088] In this regard, as described above, if the columnar body 42 has a structure that allows the mounting height of the terminal holder 45 to be changed, by changing the mounting height, the distance C can be made shorter than the depth D of the recess 42c, thereby preventing the mobile terminal 55 from falling out of the terminal holder 45 due to bouncing or the like, even if the mobile terminal 55 is short.
[0089] Although the dimensions described above prevent the mobile terminal from falling out of the terminal holder 45, if the mobile terminal 55 is bounced up due to vibration or the like, it may tilt forward or backward and come into contact with the upper edge of the terminal holder 45. In this regard, the upper end of the protective member 46 fitted into the recess 45f of the terminal holder 45 is higher than the upper end of the case portion 45a, and the upper part of the protective member 46 protrudes above the case portion 45a. Therefore, even if the mobile terminal 55 is bounced up and tilted due to vibration or the like, it will not come into direct contact with the terminal holder 45 (case portion 45a), but will come into contact with the upper part of the protective member 46, which acts as a cushion and protrudes above the case portion 45a.
[0090] Furthermore, when inserting the mobile terminal 55 into the recess 46a, it is inserted into the recess 46a from a rear-upper direction, making it prone to contact with the rear upper edge of the protective member 46. Therefore, to facilitate insertion of the mobile terminal 55 into the recess 46a, an upward-opening notch 46c is formed at a suitable depth on the rear upper edge of the upper part of the protective member 46 that protrudes upward from the case portion 45a, having a width in the left-right direction corresponding to the width of the mobile terminal 55. When the mobile terminal 55 is inserted into the recess 46a from a rear-upper direction, it is guided to contact the bottom edge of the notch 46c, thereby allowing it to be smoothly inserted into the recess 46a.
[0091] Furthermore, within the recess 46a of the protective member 46, one or more ribs 46b are formed so as to abut against the mobile terminal 55 inserted into the recess 46a. Preferably, the ribs 46b extend in the thickness direction (front-to-back direction) of the mobile terminal 55 inserted into the recess 46a.
[0092] The volume of the recess 46a is set to be somewhat large so that a mobile device 55 of any size (thickness) can be inserted. Therefore, it is possible that the mobile device 55 inserted into the recess 46a may wobble, for example, tilting back and forth. The rib 46b can suppress this wobbling of the mobile device 55.
[0093] Although the mobile terminal 55 is inserted into the recess 46a with the screen facing backward, if the terminal holder 45 is located at a low position, such as around the knees of the worker sitting in the driver's seat 26, the screen is more easily visible to the worker sitting in the driver's seat 26 if the mobile terminal 55 held by the terminal holder 45 is slightly tilted forward (the upper end is tilted forward).
[0094] Furthermore, since the mobile device 55 is inserted into the recess 46a from the rear and above, if it is tilted rear and above within the recess 46a, it is also likely to come out of the recess 46a in the rear and above direction when it bounces up due to vibration or the like. Therefore, if the mobile device 55 inserted into the recess 46a is held in a forward-tilted position (with its upper end tilted forward), it becomes less likely to come out of the recess 46a in the rear and above direction.
[0095] Therefore, in order to more reliably hold the mobile terminal 55 inserted into the recess 42c in a forward-tilted position, the contact surface of the tip of the rib 46b that abuts the mobile terminal 55 within the recess 42c may be made into a sloped surface that is in the front-up, rear-down position, and the mobile terminal 55 leaning against the slope may be configured to reliably tilt forward.
[0096] In this manner, the mobile terminal 55, which is held by the terminal holder 45 (and protective member 46) by being inserted into the recess 46a, has its bottom end in contact with the bottom end surface of the recess 42c, thereby restricting its downward movement by the terminal holder 45 (and protective member 46), and its front end surface in contact with the tip (rear end) of the rib 46b, thereby restricting its forward / backward (horizontal) movement by the terminal holder 45 (and protective member 46).
[0097] Furthermore, the movement of the mobile terminal 55 held by the terminal holder 45 in the front-to-back direction (horizontal direction) does not necessarily have to be restricted by the rib 46b. For example, the front-to-back width of the recess 46a may be made very close to the thickness of the mobile terminal 55, and the mobile terminal 55 inserted into the recess 46a may be held between the front and rear surfaces of the recess 46a, thereby restricting its movement in the front-to-back direction (horizontal direction).
[0098] In this embodiment, the display device 50 is supported at the upper end of the columnar body 42, while below it, the mounting position of the terminal holder 45 to the columnar body 42 is determined to be a single location. The terminal holder 45 positioned at this mounting position faces the display device 50 above it in the vertical direction, and the upward movement of the mobile terminal 55 held by the terminal holder 45 positioned at this location is restricted by the display device 50. Conversely, the condition for determining the mounting position of the terminal holder 45 to the columnar body 42 is to position the terminal holder 45 so that the upward movement of the mobile terminal 55 held by the terminal holder 45 can be restricted by the display device 50.
[0099] Here, since the columnar body 42 is a long member in a straight line vertically, the display device 50 (main body 51) attached to its upper end in a rearward extension and the terminal holder 45 (case portion 45a) attached to its upper and lower intermediate portion naturally face each other in the vertical direction. Therefore, if the mounting position of the terminal holder 45 to the columnar body 42 in the vertical direction can be set to a suitable position, the display device 50 and the mobile terminal 55 held by the terminal holder 45 will be in close proximity, and a state in which the upward movement of the mobile terminal 55 held by the terminal holder 45 is restricted by the display device 50 can be easily created.
[0100] As described above, the lower part of the main body 51 of the display device 50 is provided with a first slope that inclins forward downward (rear upward) and a second slope that also inclins forward upward (rear downward). The first slope and the second slope, which extends in front of it (opposite side from the driver's seat 26), are positioned above the portable terminal 55 held in the terminal holder 45.
[0101] Hereinafter, as described above, the rear lower surface 51a of the main body 51 of the display device 50 can be the first slope, and the front lower surface 51b and / or front end surface 51c of the main body 51 can be the second slope. Based on this premise, the rear lower surface 51a, which is arranged to slope in a forward downward (rear upward) direction, will be referred to as the "first slope 51a," and the front lower surface 51b and / or front end surface 51c, which are arranged to slope in a forward upward (rear downward) direction on the front side of the first slope 51a (opposite side from the driver's seat 26), will be referred to as the "second slope 51b and 51c."
[0102] The upper end of the mobile terminal 55 held by the terminal holder 45 is located just below the front end of the first inclined surface 51a, which is the lowest position on the first inclined surface 51a. On the other hand, the first inclined surface 51a, which slopes downward and forward, faces the driver's seat 26. Therefore, to an operator sitting in the driver's seat 26, the lower end of the screen display unit 52 of the display device 50 and the upper end of the mobile terminal 55 do not overlap, but appear to be separated by the second inclined surfaces 51b and 51c.
[0103] Therefore, the operator can view the entire screen shown on the display unit 52, while also being able to view almost the entire display screen of the mobile terminal 55 located below the display device 50, up to its upper end, in the portion that protrudes above the terminal holder 45 (protective member 46). In this way, the first slope 51a makes the display contents of both the display device 50 and the mobile terminal 55, which are positioned above and below each other, easily visible to the operator sitting in the driver's seat 26.
[0104] Furthermore, when inserting (attaching) the mobile terminal 55 into the terminal holder 45 and removing (detaching) it from the terminal holder 45, it is desirable that a nearly straight path for the movement of the mobile terminal 55 is ensured between the recess 46a of the terminal holder 45 and the hands of the worker seated in the driver's seat 26 located above it, without interference with other objects. The first inclined surface 51a, which slopes downward and backward (upward and backward), extends directly above the said path and is nearly parallel to it. This prevents interference between the display device 50 and the mobile terminal 55 or the hand holding it while it is moving along the path, and the first inclined surface 51a can also serve as a guide to direct the mobile terminal 55 along the path when inserting it into the recess 46a of the terminal holder 45 and when removing it from the recess 46a.
[0105] Furthermore, while the mobile terminal 55 inserted into the recess 46a is held in the terminal holder 45 in a vertical or nearly vertical position, when the terminal holder 45 is inserted into the recess 46a and the recess When the mobile terminal 55 is removed from 46a (while moving along the aforementioned path), it is generally tilted forward and downward. By first placing the mobile terminal 55 in the notch 46c of the protective member 46, it can smoothly transition from a tilted state along the path to an upright state within the recess 46a when inserted into the recess 46a, and can smoothly transition from an upright state within the recess 46a to a tilted state along the path when removed from the recess 46a.
[0106] With the configuration of the display device 50 and terminal holder 45 (protective member 46) as described above, the operator sitting in the driver's seat 26 can easily and reliably view the display contents of the display devices 50 and the portable terminal 55, which are arranged vertically, and can easily insert the portable terminal 55 into the terminal holder 45 (recess 46a) and remove it from the terminal holder 45 (recess 46a).
[0107] Therefore, for example, when the mobile terminal 55 rings, the user can first easily check the information and messages displayed on the mobile terminal 55 held in the terminal holder 45, then immediately take the mobile terminal 55 out of the terminal holder 45 to answer the call, and immediately return the mobile terminal 55 to the terminal holder 45 after answering the call.
[0108] The lower part of the mobile terminal 55, which is fitted into the recess 42c, is held by the terminal holder 45 via a protective member 46 equipped with ribs 46b, etc., as described above, with its horizontal (front-to-back) and downward movement restricted. The mobile terminal 55 is held by the terminal holder 45 with its display screen facing the rear towards the driver's seat 26, and with most of it protruding above the terminal holder 45 (protective member 46) in the vertical direction. As a result, the operator can see the display screen of the mobile terminal 55 (most of which protrudes above the terminal holder 45) while sitting in the driver's seat 26.
[0109] Furthermore, the upper end of the portable terminal 55, when fitted into the recess 42c and held by the terminal holder 45, is close in the vertical direction to the front end of the first inclined surface 51a, which is the lowest point on the lower part of the display device 50, and is located slightly in front of the front end of this first inclined surface 51a in the front-to-back direction. In other words, the upper end of the portable terminal 55 held by the terminal holder 45 is directly below the second inclined surfaces 51b and 51c (or the front lower surface 51b arranged horizontally) of the main body 51 of the display device 50.
[0110] Even when the lower part of the mobile terminal 55 is housed within the recess 42c, it may bounce upward due to vibrations from the working machine 1 during operation, for example. However, even if it bounces upward, it will come into contact with the second inclined surfaces 51b and 51c directly above it (or the front lower surface 51b arranged horizontally), and will not be able to move any further upward. In this way, the mobile terminal 55 held by the terminal holder 45 is restricted from moving upward by the lower part of the main body 51 of the display device 50 located directly above it.
[0111] Furthermore, because the second slopes 51b and 51c are inclined forward and upward, the upper end of the mobile terminal 55 that contacts the second slopes 51b and 51c does not tilt backward along the first slope 51a, but rather tilts forward along the second slopes 51b and 51c. Since the case portion 45a of the terminal holder 45 is located behind the columnar body 42, the columnar body 42 (more precisely, the cover member 43 attached to the rear surface of the columnar body 42) is located directly in front of the mobile terminal 55 held by the case portion 45a. Therefore, even if the mobile terminal 55 moves forward and upward along the second slopes 51b and 51c, it immediately hits the columnar body 42 (cover member 43), preventing it from moving any further forward and upward.
[0112] As described above, the first inclined surface 51a of the main body 51 of the display device 50 functions as a surface that guides the mobile terminal 55 in order to facilitate the insertion of the mobile terminal 55 into the terminal holder 45 and the removal of the mobile terminal 55 from the terminal holder 45, whereas the second inclined surface 51a of the main body 51 of the display device 50 Surfaces 51b and 51c guide the mobile terminal 55, which is held in the terminal holder 45, toward the columnar body 42 on the opposite side from the first inclined surface 51a, even if the mobile terminal 55 moves upward, thereby preventing the mobile terminal 55 from coming out of the terminal holder 45. Thus, they function as guide surfaces to prevent the mobile terminal 55 from coming out.
[0113] In addition to the forward-upward sloping second inclined surfaces 51b and 51c, as described above, by making the tip of the rib 46b that contacts the mobile terminal 55 within the recess 42c, and the front surface of the recess 46a, which has a front-to-back width set to a dimension close to the thickness of the mobile terminal 55, forward-upward sloping surfaces, the mobile terminal 55 moving upward can be guided more reliably toward the columnar body 42, which acts as a retainer for the mobile terminal 55.
[0114] Furthermore, just as the display device 50 may be attached to the handrail 41, the terminal holder 45 may also be attached to the handrail 41 or to a column 41a or auxiliary rod 41b provided integrally with the handrail 41. In other words, at least one of the display device 50 and the terminal holder 45 may be attached to the handrail 41 or to a column 41a or auxiliary rod 41b provided integrally with the handrail 41.
[0115] For example, the terminal holder 45 may be attached to the auxiliary rod portion 41b, and the display device 50 may be attached to the handrail 41 above it. Alternatively, the display device 50 may be attached to the upper part of the column portion 41a, and the terminal holder 45 may be attached to the upper or lower part of the column portion 41a. In these cases as well, for example, the depth D of the recess 46a of the terminal holder 45 (protective member 46) may be greater (deeper) than the distance C between the upper end of the portable terminal 555 held by the terminal holder 45 and the display device 50.
[0116] Furthermore, the display device 50 or terminal holder 45 attached to the handrail 41, etc., may be repositionable in the vertical direction. In this case, for example, the relative position of the display device 50 and the terminal holder 45 may be changed such that the distance C between the upper end of the portable terminal 55 held by the terminal holder 45 and the display device 50 is shorter than the depth D of the recess 46a of the terminal holder 45 (protective member 46).
[0117] Next, we will explain the effects of several configurations of the work machine 1 equipped with a display device 50 and a terminal holder (holding member) 45.
[0118] (Item 1) A work machine 1 comprising a machine body 20, a driver's seat 26 provided on the machine body 20, a display device 50 positioned near the driver's seat 26, and a holding member 45 capable of holding a mobile terminal 55 by restricting its downward and horizontal movement, wherein the holding member 45 is positioned below the display device 50, facing the display device 50 in the vertical direction, and the upward movement of the mobile terminal 55 held by the holding member 45 is restricted by the display device 50.
[0119] As a result, the display device 50 restricts the upward movement of the mobile terminal 55, which cannot be fully restricted by the retaining member 45. Therefore, the support member (columnar body 42) that supports the display device 50 and the retaining member 45 does not need to undergo complex processing to restrict the movement of the mobile terminal 55, such as forming a step. Furthermore, since the display device 50 and the retaining member 45 can be positioned opposite each other in the vertical direction, the support member (columnar body 42) can be a simple shape, such as a long, nearly straight vertical section. Consequently, even in cases where there are no existing members suitable for mounting the display device 50 and the retaining member 45 at the desired position, such as in the canopy-mounted work machine 1, and it is necessary to provide a new support member, the cost of adding the support member can be kept low, contributing to the reduction of the manufacturing cost of the work machine 1.
[0120] (Item 2) The work machine 1 according to Item 1, wherein the display device 50 has a main body 51 and a screen display unit 52 provided on the driver's seat 26 side of the main body 51, and a first slope 51a is formed on the lower part of the main body 51 of the display device 50, which slopes downward as it moves toward the opposite side from the driver's seat 26.
[0121] As a result, to the operator sitting in the driver's seat 26, the display screens on the screen display units 52 of the vertically aligned display devices 50 and the display screen of the portable terminal 55 held by the holding member 45 appear to be separated by the first inclined surface 51a formed on the main body 51 of the display device 50, allowing each display screen to be clearly seen. Furthermore, this first inclined surface 51a can be used as a guide surface for the portable terminal 55 when the operator sitting in the driver's seat 26 inserts the portable terminal 55 into the holding member 45 and when removing the portable terminal 55 from the holding member 45. Moreover, since this first inclined surface 51a is formed on the main body 51 of the display device 50, rather than on a support member (columnar body 42) that has the necessary rigidity to support the display device 50 and the holding member 45, it can be formed from a material that does not require much rigidity, is inexpensive, and is easy to shape, such as a case member which is the exterior of the main body 51, thus contributing to reducing the manufacturing cost of the work machine 1.
[0122] (Item 3) The work machine 1 according to Item 2, wherein the lower part of the main body 51 of the display device 50 has second slopes 51b and 51c formed thereon, which extend from the first slope 51a on the side opposite to the driver's seat 26 and which slope upward as they move toward the opposite direction.
[0123] As a result, the second inclined surfaces 51b and 51c formed on the main body 51 of the display device 50 can be used as restricting surfaces that restrict the upward movement of the portable terminal 55 held by the holding member 45, and as guide surfaces that guide the portable terminal 55, which is moving upward, not toward the first inclined surface 51a on the driver's seat 26 side, which is the direction in which the portable terminal 55 is attached to and detached from the holding member 45, but toward the opposite side, the side that prevents the portable terminal 55 from coming off. Furthermore, similar to the first inclined surface 51a, the second inclined surfaces 51b and 51c can also be formed from inexpensive and easily shaped materials, such as the case member which is the exterior of the main body 51 of the display device 50, which can contribute to reducing the manufacturing cost of the work machine 1.
[0124] (Item 4) The work machine 1 according to any one of items 1 to 3, comprising a columnar body 42 erected on the machine body 20 and supporting the display device 50, wherein the holding member 45 is attached to the driver's seat 26 side of the columnar body 42.
[0125] As a result, the display device 50 and the columnar body 42 are supported by a single columnar body 42, which reduces the number of parts. Furthermore, in combination with the configuration of item 1, the columnar body 42 can be a simple-shaped component that does not require complex processing, thus contributing to cost reduction. In addition, since the mobile terminal 55 is held by the holding member 45 attached to the driver's seat 26 side of the columnar body 42, the display screen of the mobile terminal 55 can be turned toward the driver's seat 26, making it easily visible to the operator sitting in the driver's seat 26. Conversely, from the driver's seat 26, the columnar body 42 is hidden behind the mobile terminal 55 and the holding member 45, so the area around the display screen of the mobile terminal 55 looks neat and tidy. Furthermore, especially in conjunction with the configuration of item 3, the columnar body 42 is located on the opposite side of the driver's seat 26 of the holding member 45, and restricts the upward movement of the portable terminal 55 which is guided on the opposite side of the driver's seat 26 by the second slopes 51b and 51c. Thus, the columnar body 42 itself can function as a retaining member for the portable terminal 55 to escape from the holding member 45. In this way, the configuration related to item 4 can contribute to improving the appearance of the work machine 1, improving the effect of preventing the portable terminal 55 held by the holding member 45 from falling out, and reducing the manufacturing cost of the work machine 1.
[0126] (Item 5) The work machine 1 according to Item 4, wherein the display device 50 and / or the holding member 45 are attached to the columnar body 42 so as to be able to change their vertical position.
[0127] This allows for the configuration described in item 1, in which the display device 50 restricts the upward movement of the mobile terminal 55 held by the holding member 45, by adjusting the vertical distance between the display device 50 and the mobile terminal 55 held by the holding member 45, for example, in response to differences in the size of the mobile terminal 55 that is to be held by the holding member 45.
[0128] (Item 6) The work machine 1 according to any one of Items 1 to 5, comprising a handrail 41 positioned near the driver's seat 26, and a columnar body 42 erected on the machine body 20 and connected to the handrail 41, wherein the display device 50 and the holding member 45 are attached to the columnar body 42 or the handrail 41.
[0129] As a result, the location in the work machine 1 where the display device 50 and the holding member 45 are desirable is a location where the worker sitting in the driver's seat 26 can easily see the display contents of the portable terminal 55 held by the display device 50 and the holding member 45 while observing the status of the work device 30, and where the harness H inserted through the columnar body 42 can be easily connected to the display device 50. Thus, the range of locations that can be selected as suitable for the placement of the display device 50 and the holding member 45 can be expanded.
[0130] (Item 7) The work machine 1 according to Item 6, wherein the display device 50 and / or the holding member 45 are attached to the columnar body 42 or the handrail 41 so as to be able to change their vertical position.
[0131] As a result, when it is necessary to adjust the distance between the mobile terminal 55 held by the holding member 45 and the display device 50, for example, in response to the replacement of the mobile terminal 55 held by the holding member 45, the display device 50 and / or the holding member 45 attached to the columnar body 42 or handrail 41 can be easily done by changing the vertical position of the display device 50 and / or the holding member 45.
[0132] (Item 8) The work machine 1 according to any one of Items 1 to 7, wherein the holding member 45 is provided with an upwardly opening recess 46a for holding the lower part of the mobile terminal 55 that is inserted from above, and the depth D of the recess 46a is greater than the distance C between the upper end of the mobile terminal 55 held by the holding member 45 and the display device 50.
[0133] As a result, even if the upper end of the mobile terminal 55, which has been propped up by vibration or the like, reaches its maximum height and abuts the display device 50, the lower end of the mobile terminal 55 will be located within the recess 46a below the upper opening of the recess 46a, preventing the mobile terminal 55 from being propped up any higher and its lower end from coming out of the recess 46a of the retaining member 45. In other words, by setting the depth D of the recess 46a of the retaining member 45 and the distance C between the retaining member 45 and the display device 41 in this way, the mobile terminal 55 is prevented from being propped up and detached from the retaining member 45.
[0134] (Item 8) The work machine 1 according to any one of Items 1 to 8, wherein the holding member 45 has an upwardly opening recess 46a for holding the lower part of the mobile terminal 55 that is inserted from above, and the relative position of the display device 50 and the holding member 45 can be changed such that the distance C between the upper end of the mobile terminal 55 held by the holding member 45 and the display device 50 is shorter than the depth D of the recess 46a.
[0135] As a result, for example, if the mobile terminal 55 held by the holding member 45 is changed to a model with a shorter vertical length, the distance C between the upper end of the mobile terminal 55 held by the holding member 45 and the display device 50 may change, and even if this distance C becomes longer than the depth D of the recess 42c, the distance C can be changed by changing the relative position between the display device 50 and the terminal holder 45 to the depth of the recess 42c. By making it shorter than D, even with such a short mobile terminal 55, it is possible to prevent the mobile terminal 55 from coming loose from the holding member 45 due to bouncing or other reasons.
[0136] While embodiments of the present invention have been described above, the embodiments disclosed herein should be considered in all respects to be illustrative and not restrictive. The scope of the present invention is indicated by the claims rather than by the foregoing description, and all modifications within the meaning and scope of equivalence to the claims are intended to be included.
