Description

[Technical field]

[0001] The present invention relates to a drink holder for a work machine. [Background technology]

[0002] Conventionally, in a work machine, a configuration is known in which a drink holder having a cold or warming function is installed in the driver's cab (for example, see Patent Document 1). This cold or warming function is achieved by blowing temperature-controlled air (cold air or warm air) from an air conditioner to the drink holder.

[0003] The drink holder described in Patent Document 1 has a configuration in which a holder that surrounds and holds at least the lower part of a beverage container is rotatably fitted into a recess in the surface of a vehicle interior component. An inlet is formed on the side of the holder, and an opening through which temperature-controlled air is discharged is formed on the side of the recess. By rotating the holder relative to the recess so that the inlet faces the opening, the temperature-controlled air is introduced into the holder, and by rotating the holder so that the opening and the inlet are not opposed to each other, the introduction of the temperature-controlled air into the holder can be stopped. In other words, by rotating the holder, a shutter composed of the opening and the inlet can be opened and closed. [Prior art documents] [Patent documents]

[0009] Hereinafter, the embodiment of the present invention will be described with reference to the drawings. The following description and drawings are examples for explaining the present invention, and are omitted and simplified as appropriate for clarity of explanation. In addition, in the following description, the same or similar elements and processes are given the same reference numerals, and duplicate explanations may be omitted. Note that the contents described below are merely examples of the embodiment of the present invention, and the present invention is not limited to the following embodiment, and can be implemented in various other forms.

[0010] FIG. 1 is a diagram showing the external appearance of a hydraulic excavator 1, which is a representative example of construction machinery. The hydraulic excavator 1 includes a crawler-type lower traveling body 2 that is self-propelled in the front-rear direction, and an upper rotating body 3 mounted on the lower traveling body 2. The upper rotating body 3 is mounted on the lower traveling body 2 via a rotating device 4, and is mounted so as to be rotatable relative to the lower traveling body 2. The lower traveling body 2 includes crawlers 2b on both the left and right sides, which are driven by traveling motors 2a. A working device 5 is provided in front of the upper rotating body 3, and the working device 5 is composed of a boom 5a, an arm 5b, and a bucket 5c. A driver's cab 6 is provided in front of the upper rotating body 3.

[0011] FIG. 2 is a diagram showing a schematic configuration inside the cab 6. In FIG. 2, the direction of the arrow AB is the left-right direction of the cab 6. A seat 10 on which an operator sits is provided in the center of the cab 6. Work operation levers 11a, 11b are provided on both the left and right sides of the seat 10. The operator can operate the work device 5 and the upper rotating body 3 by grasping and operating the work operation levers 11a, 11b. In addition, a travel operation lever 12 for operating the operation of the lower traveling body 2 is provided in front of the seat 10. An interior cover 13 in the cab 6 is provided with a drink holder DH.

[0012] As will be described later, drink holder DH comprises holder portion 20 for holding a beverage container or the like, and shutter 30 for turning on and off the temperature-controlled air supplied to holder portion 20 (see FIG. 6, which will be described later). Figure 3 is an enlarged view of holder portion 20 of drink holder DH attached to interior cover 13 in Figure 2. Note that shutter 30 is not shown in Figure 3.

[0013] Holder part 20 of drink holder DH is formed with a storage recess 201 for holding a beverage container such as a beverage container or a paper cup. Storage recess 201 has small-diameter inner circumferential surface 203a located on the bottom surface 202 side of holder part 20, and large-diameter inner circumferential surface 203b located on the recess opening side. Inner circumferential surface 203a and inner circumferential surface 203b are connected by a stepped surface 204. The beverage container is held on bottom surface 202 or stepped surface 204 depending on the thickness of the beverage container.

[0014] Drink holder DH is formed with ventilation opening 200 penetrating from the inside to the outside. Meanwhile, interior cover 13 is provided with air outlet 130 for temperature-controlled air (cold air or hot air) from an air conditioner that conditions the interior of driver's cab 6, adjacent to ventilation opening 200. The temperature-controlled air blown out from air outlet 130 passes through ventilation opening 200 and is supplied into storage recess 201 of drink holder DH. As a result, the beverage container held in storage recess 201 is cooled in the case of cold air, and the beverage container is warmed in the case of hot air.

[0015] Interior cover 13 and drink holder DH are formed from separate members. Drink holder DH is removably fixed to interior cover 13 by a fitting structure as shown in Fig. 4. Fig. 4 is a diagram explaining the fitting structure, showing the drink holder DH removed upward from interior cover 13. Elliptical convex portions 131a, 131b are formed facing upward. Meanwhile, fitting recesses 205a, 205b are formed on the back side of drink holder DH at positions facing convex portions 131a, 131b.

[0016] When drink holder DH is moved in the direction of the arrow from the state shown in Fig. 4, the upper ends of convex portions 131a, 131b come into contact with the entrances of mating recesses 205a, 205b. When drink holder DH is further pressed down in the direction of the arrow, mating recesses 205a, 205b are elastically deformed to the left and right in the figure by the pressed convex portions 131a, 131b, and convex portions 131a, 131b fit into mating recesses 205a, 205b.

[0017] Fig. 5 is a diagram showing convex portions 131a, 131b and mating recesses 205a, 205b in an engaged state, and is a diagram showing drink holder DH in Fig. 3 as viewed in the direction of arrow R. Drink holder DH is fixed to interior cover 13 by convex portions 131a, 131b and mating recesses 205a, 205b being in an engaged state.

[0018] Conversely, when removing drink holder DH from interior cover 13 in the mated state shown in Fig. 5, drink holder DH is lifted upward. As a result, mating recesses 205a, 205b elastically deform to open their openings widely, and convex portions 131a, 131b come out of mating recesses 205a, 205b, thereby removing drink holder DH from interior cover 13. Note that, although convex portions 131a, 131b are formed on interior cover 13 and mating recesses 205a, 205b are formed on holder portion 20 in the example shown in Figs. 4 and 5, conversely, convex portions 131a, 131b may be formed on holder portion 20 and mating recesses 205a, 205b may be formed on interior cover 13.

[0019] By providing convex portions 131a, 131b and mating concave portions 205a, 205b and making drink holder DH (holder portion 20 and shutter 30) detachable from interior cover 13, cleaning can be performed with holder portion 20 removed. In the case of a drink holder DH for a work machine, vibrations of the work machine, dust during work, and the like can easily cause beverages to spill onto holder portion 20 or it can become dirty with dust. In such cases, holder portion 20 can be easily cleaned by removing it from interior cover 13 and washing it with water, etc. Furthermore, if holder portion 20 or shutter 30 is broken, it is sufficient to replace only drink holder DH.

[0020] Moreover, the shutter 30 can be easily removed from the guide groove 206 of the holder portion 20 by simply removing the pin 31. This makes it easy to clean the shutter 30 and the guide groove 206 and to replace the shutter 30.

[0021] Figures 6 to 9 are diagrams illustrating the shutter mechanism of drink holder DH. Figure 6 is an exploded perspective view of drink holder DH. Shutter 30 comprises a horizontal slide plate 300, a knob 301 protruding vertically from the upper surface of slide plate 300, and a shielding plate 302 formed vertically on the lower surface of slide plate 300. Furthermore, a stopper 303 is formed to protrude from the lower surface of slide plate 300.

[0022] The drink holder DH is formed with a guide groove 206 extending in the left-right direction. The shielding plate 302 of the shutter 30 is inserted into the guide groove 206. The shielding plate 302 is formed with a ventilation opening 304 in an area to the right of the stopper 303 in the figure. Furthermore, the shielding plate 302 is formed with a horizontally elongated opening 305 in an area below the stopper 303 in the figure. The above-mentioned ventilation opening 200 is formed on the outer wall side of the guide groove 206, and a hole 207a is formed on the inner wall side.

[0023] Although not visible in Fig. 6, hole 207b (see Fig. 5) is formed below ventilation opening 200 on the outer wall side of guide groove 206 at a position opposite hole 207a. Pin 31 is attached to holes 207a and 207b. Shutter 30 is attached to drink holder DH by inserting retaining pin 31 through opening 305 of shielding plate 302 inserted in guide groove 206.

[0024] 7 is a cross-sectional view of a part of the holder part 20 and the shutter 30, taken along a vertical plane extending in the front-rear direction through the axis of the pin 31 in FIG. 6. As described above, the shielding plate 302 formed on the lower surface of the slide plate 300 is inserted into the guide groove 206. The shaft 310 of the pin 31 inserted into the opening 302a of the shielding plate 302 is attached to the holes 207a, 207b formed in the wall of the holder part 20. In FIG. 7, the shutter 30 is in a closed state in which the non-opening region of the shielding plate 302 faces the ventilation opening 200 of the holder part 20.

[0025] Fig. 8 shows drink holder DH when shutter 30 is in an open state, and Fig. 9 shows drink holder DH when shutter 30 is in a closed state. An operator seated on seat 10 operates knob 301 provided on slide plate 300 in the left-right direction (the direction of arrow AB), causing slide plate 300 to slide left and right. In Fig. 8, slide plate 300 has been moved leftward until stopper 303 abuts on the wall of holder portion 20 on the left side in the figure. As a result, ventilation opening 304 of shielding plate 302 faces ventilation opening 200 of holder portion 20, and temperature-controlled air is supplied to accommodation recess 201 of holder portion 20.

[0026] 9, the slide plate 300 is moved to the right until the stopper 303 abuts against the wall portion on the right side of the holder part 20. As a result, the ventilation opening 200 of the holder part 20 is blocked by the shielding plate 302 of the shutter 30, and the supply of temperature-controlled air to the holder part 20 is stopped.

[0027] Incidentally, in the drink holder described in Patent Document 1, as described above, the shutter is opened and closed by rotating the holder with the beverage container inserted. Therefore, there is a risk that, for example, the beverage liquid in the paper cup held in the holder may spill out or the beverage container may become unstable and fall out of the holder due to the influence of the holder rotating action. There is also a risk that the holder may fall out of the recessed portion when the holder is rotated.

[0028] Meanwhile, in the drink holder DH of the present embodiment described above, the shutter 30 is opened and closed by operating knob 301 of slide plate 300, which is provided separately from holder part 20 that holds the beverage container, left and right to slide slide plate 300 left and right. Therefore, the holding state of the beverage container placed in storage recess 201 is not adversely affected, and it is possible to prevent the beverage container from falling and the beverage liquid in the paper cup from spilling.

[0029] 6, 8, etc., the sliding direction of the slide plate 300 accompanying the opening and closing of the shutter is the left-right direction of the cab 6, and is perpendicular to the attachment / detachment direction (up-down direction) of the holder part 20 relative to the interior cover 13. This makes it possible to prevent the holder part 20 from coming off and falling off the interior cover 13 due to the opening and closing operation of the shutter. Note that, although the sliding direction of the slide plate 300 is the left-right direction in the embodiment, it is not limited to the left-right direction as long as it is perpendicular to the attachment / detachment direction.

[0030] Furthermore, when the hydraulic excavator 1 (working machine) vibrates, for example when the hydraulic excavator 1 is driven in the fore-and-aft direction of the operator's cab 6, vibrations in the fore-and-aft direction (vibrations in the direction of arrows CD in FIG. 8) become noticeable in the operator's cab 6. However, since the slide plate 300 is configured to be slidable in the left-and-right direction within the guide groove 206, movement of the slide plate 300 in the left-and-right direction due to vibrations in the fore-and-aft direction is unlikely to occur, and changes in the open / closed state of the shutter due to vibrations can be prevented.

[0031] According to the embodiment of the present invention described above, the following advantageous effects are achieved.

[0032] (1) As shown in Figures 6, 8 and 9, the drink holder DH of the hydraulic excavator 1 (work machine) is a drink holder into which temperature-controlled air from the air conditioner of the hydraulic excavator 1 (work machine) is guided, and is removably fixed to interior cover 13 in the operator's cab 6 of the hydraulic excavator 1, and comprises a holder portion 20 which is formed with a storage recess 201 in which a beverage container is stored and a ventilation opening 200 which guides temperature-controlled air to the storage recess 201, and a shutter 30 which is provided on the holder portion 20 and is movable between a closed position which blocks ventilation opening 200 (the state shown in Figure 9) and an open position which opens ventilation opening 200 (the state shown in Figure 8).

[0033] Thus, drink holder DH is provided with shutter 30 that is movable relative to holder portion 20 fixed to interior cover 13. Then, opening and closing operation by shutter 30 is performed by moving shielding plate 302 between a closed position in which ventilation opening 200 is blocked by shielding plate 302 of shutter 30 as shown in Fig. 9, and an open position in which ventilation opening 304 faces ventilation opening 200 as shown in Fig. 8. As a result, it is possible to prevent a beverage container from falling or beverage liquid from a paper cup from spilling due to the shutter opening and closing operation as in the past.

[0034] (2) As shown in Fig. 8, the direction in which holder portion 20 is attached to and detached from interior cover 13 is different from the direction in which shutter 30 (slide plate 300) moves. This makes it possible to prevent holder portion 20 from coming off interior cover 13 and falling off due to the shutter opening and closing operation. In particular, it is preferable to configure the direction in which shutter 30 is attached and detached and the direction in which shutter 30 moves perpendicular to each other, which reliably prevents holder portion 20 from falling off when the shutter is opened and closed.

[0035] (3) As shown in Figures 4 and 5, either one of the convex parts 131a, 131b or the mating concave parts 205a, 205b that can be mated with each other is provided in the interior cover facing area of ​​the holder part 20 (the bottom part of the holder part 20), and the other of the convex parts 131a, 131b and the mating concave parts 205a, 205b is provided in the holder fixing area of ​​the interior cover 13. In the example shown in Figures 4 and 5, the convex parts 131a, 131b are provided on the interior cover 13, and the mating concave parts 205a, 205b are provided on the holder part 20.

[0036] When the holder part 20 is biased in the attachment / detachment direction (arrow direction in FIG. 4) relative to the holder fixing region, the convex parts 131a, 131b and the mating concave parts 205a, 205b are mated, and the holder part 20 is fixed to the interior cover 13. On the other hand, when the holder part 20 is pulled away from the holder fixing region of the interior cover 13 in the attachment / detachment direction, the mating state between the convex parts 131a, 131b and the mating concave parts 205a, 205b is released, and the holder part 20 is separated from the interior cover 13.

[0037] Providing such convex portions 131a, 131b and mating concave portions 205a, 205b facilitates attachment and detachment of holder portion 20 to interior cover 13. In the mated state, holder portion 20 is reliably fixed to interior cover 13 without falling off due to vibration or the like.

[0038] The above-described embodiment is merely an example, and the present invention is not limited to these embodiments as long as the features of the invention are not impaired. Other aspects conceivable within the scope of the technical idea of ​​the present invention are also included within the scope of the present invention. For example, in the above-described embodiment, a drink holder for a hydraulic excavator was used as an example, but the above-described drink holder DH can be applied to various types of work machines, not limited to hydraulic excavators.
