Description
- The present invention relates to a structure for mounting a mountable/dismountable component on the body of a working machine.
- Some of various working machines, such as agricultural working machines and snow removal machines, are driven by an electric motor. For example, a battery for driving an electric motor is mounted on the body of an electrically-driven working machine. Among the conventionally known techniques concerning a mounting structure for a mountable/dismountable component, such as a battery, is one disclosed in Japanese Utility Model Application Laid-open Publication No.
HEI-4-110648 Patent Literature 1 "). - In the mountable/dismountable component mounting structure disclosed in
Patent Literature 1, the body of the working machine has a slit hole and a bolt-connected flange, while the battery has a tongue section and a bolt hole. - To mount the battery on the machine body, the tongue section of the battery is inserted into the slit hole of the machine body, and then the bolt-connected flange and the bolt hole are interconnected via a bolt. Particularly, in the case of a working machine where the battery is charged indoors, mounting and dismounting of the battery is carried out frequently.
- However, with the mountable/dismountable-component mounting structure disclosed in
Patent Literature 1, the bolt might be lost with the battery dismounted from the machine body. In addition, a tool is necessary to attach the bolt, and the operation for mounting the mountable/dismountable component would take much time and labor. -
JP 2011 220033 A claim 1. - In view of the foregoing prior art problems, it is an object of the present invention to provide an improved technique which allows a mountable/dismountable component to be mounted on the body of a working machine without using a fastener such as a bolt.
- In order to accomplish the above-mentioned object, the present invention provides a working machine in accordance with
claim 1. - The structure for mounting a mountable/dismountable component on a machine body of a working machine comprises: a plurality of locking sections provided on the machine body for locking the mountable/dismountable component; and a plurality of engagement sections provided on the mountable/dismountable component and engageable by respective ones of the plurality of locking sections, the plurality of locking sections including: a movable locking section capable of sliding the mountable/dismountable component to a predetermined mounting position on the machine body while locking a first engagement section of the engagement sections; and a fixed locking section constructed to lock a second engagement section, different from the first engagement section, of the engagement sections of the mountable/dismountable component in the predetermined mounting position.
- According to the present invention, the machine body has the plurality of locking sections, and the mountable/dismountable component has the plurality of engagement sections engageable by the respective locking sections. The locking sections includes: the movable locking section capable of sliding the mountable/dismountable component to the predetermined mounting position on the machine body while locking the first engagement section of the component; and the fixed locking section constructed to lock the second engagement section of the component in the predetermined mounting position. Namely, by a human operator operating the movable fitting section provided on the machine body, the mountable/dismountable component is locked in the mounting position. Thus, the present invention allows the mountable/dismountable component to be fixedly mounted on the machine body without using a particular fastener, such as a bolt. Besides, there is no need to prepare a particular tool at the time of mounting of the mountable/dismountable component. In this way, the present invention allows the mountable/dismountable component to be mounted on the machine body with utmost ease without using a particular fastener, such as a bolt, and a particular tool.
- Preferably, in the structure of the present invention, the fixed locking section is formed in a hooked shape adapted to opposedly engage the second engagement section sliding toward the mounting position. Various loads tend to be applied to the machine body from outside during operation of the working machine. The fixed locking section is formed in a hooked shape adapted to opposedly engage the second engagement section, and thus, even when a load has been input to the machine body, the present invention can prevent excessive displacement of the mountable/dismountable component.
- In the structure of the present invention, the second engagement section is provided on each of left and right sides of the mountable/dismountable component as left and right second engagement sections extending outwardly away from each other in a width direction of the mountable/dismountable component, and the mountable/dismountable component further includes left and right taper sections formed on left and right side portions of the mountable/dismountable component and located inwardly, in the width direction of the mountable/dismountable component, of corresponding ones of the second engagement sections, each of the left and right taper sections tapering continuously to the corresponding second engagement section. In mounting operation, the mountable/dismountable component may sometimes be placed on a position of the machine body deviated from a predetermined position leftward or rightward in the width direction of the machine body. In such a case, as the mountable/dismountable component is slid toward the predetermined mounting position, any one of the left and right taper sections abuts against the corresponding second engagement section. As the mountable/dismountable component is further slid toward the predetermined mounting position, the mountable/dismountable component is slid laterally
toward the centerline, i.e. in a width direction of the machine body, by the action of the slanting surface of the taper section, so that the mountable/dismountable component can be easily mounted on the predetermined mounting position of the machine body. Thus, the mountable/dismountable component can be mounted accurately on the predetermined mounting position through a simple operation by the human operator, i.e. by the human operator operating only the movable locking section. - Preferably, the structure of the present invention further comprises a push-back portion capable of contacting the first engagement section. When the mountable/dismountable component is to be dismounted from the machine body, the push-back portion abuts against the first engagement section to slide the first engagement section from the mounting position to a position where the mountable/dismountable component is dismountable from the machine body. The human operator can dismount the mountable/dismountable component from the machine body by lifting up mountable/dismountable component located in the dismounting position. In the dismounting operation, it is not necessary for the human operator to slide the mountable/dismountable component to the dismounting position. In this way, the present invention allows the mountable/dismountable component to be easily dismounted from the machine body with a simple operation.

right travel devices 12 are each in the form of a crawler. The snow disposal member (dozer) 13 can push out snow as thesnow removal machine 10 is caused to travel forward. Thedrive source 14, which is for example in the form of an electric motor, drives the left andright travel devices 12. Thedrive source 14 is supplied with electric power output from thebattery 16. The left andright operating handles 15 extend obliquely upward and rearward from the rear portion of themachine body 11 and have left and right grips 17 (only theleft grip 17 is shown in the figure) on their respective distal end portions. The human operator can operate the left andright operating handles 15 while waking together with thesnow removal machine 10 with the left andright grips 17 held by his or her both hands. Further, acontrol section 18 for controlling the driving operation of themotor 14 is mounted on themachine body 11. - Further, a battery attachment/
detachment mechanism 30 is provided on themachine body 11. Thebattery 16 is mountable and dismountable on and from themachine body 11 by the human operator manipulating the battery attaclament/detachment mechanism 30. - In
Figs. 1 to 3 , thebattery 16 is shown as mounted on and fixed to themachine boy 11; it can also be said that thebattery 16 is located in a predetermined mounting position on themachine body 11. - As shown in
Figs. 2 and3 , the battery attachment/detachment mechanism 30 includes: afirst shaft member 31 fixed to astay 21 that is in turn secured to a front portion of thecontrol section 18; ahandle plate 40 pivotably connected to thefirst shaft member 31; arod 33 pivotably and displaceably connected to thehandle plate 40; asecond shaft member 34 fixed to a central portion, in a width direction (left-right direction), of themachine body 11; aslide unit 50 connected to therod 33 and thesecond shaft member 34 for sliding thebattery 16 in a forward-rearward direction; aspring 36 normally biasing theslide unit 50 downwardly and normally biasing therod 33 upwardly;fastener members 37 fixed to left and right rear side portions of themachine body 11; left andright locking plates 38 fixed to corresponding ones of thefastener members 37; and aguide member 39 fixed to the rear end of themachine body 11. - The
battery 16 includes a front engagement section (also referred to as "first engagement section") 71 fixed to a front middle portion of thebattery 16 and engageable by theslide unit 50, and pin-shaped left and right rear engagement sections (also referred to as "second engagement sections") 75 fixed to left and right rear portions of thebattery 16 and engageable by the left andright locking plates 38. - The
stay 21 is joined to and supported by a controlsection support plate 22 that is fixed to themachine body 11 for supporting thecontrol section 18. Thus, it can be said that thestay 21, thefirst shaft member 31 and thehandle plate 40 are supported by themachine body 11. - The
handle plate 40 includes two L-shapedplates 41 each having a generally L shape as viewed in side elevation of themachine body 11, aconnection plate 42 joined to the two L-shapedplates 41 to interconnect the L-shapedplates 41, and agrip plate 43 joined to one end portion of theconnection plate 42 and capable of being gripped by the human operator in operating themachine 10. - Each of the L-shaped
plates 41 has aninsertion hole 41a having thefirst shaft member 31 inserted therethrough, and only one of the L-shapedplates 41 has arod insertion hole 41b having therod 33 inserted therethrough. - The
grip plate 43 is fixed to a distal end portion of theconnection plate 42 and extends rearward away from thefirst shaft member 31 beyond the distal end of one side of the L-shapedplates 41. Therod 33 has an upper end portion inserted through thehole 41b formed in a corner portion of theplate 41 near the distal end of another side (vertical side inFig. 2 ). Thefirst shaft member 31 is inserted through theinsertion hole 41a near a middle portion of the other side of the L-shapedplate 41. - The
rod 33 is a rod-shaped member of a generally L shape having an upper end portion bent toward the L-shapedplate 41. Therod 33 has anabutment section 33a on a lower portion thereof, and thespring 36 is abutted at one end against theabutment section 33a. Theabutment section 33a may be formed, for example, by crushing the lower portion of therod 33. - Referring now to
Figs. 2 and4 , theslide unit 50 includes two, i.e. left and right,slide plates 60 disposed in such a manner that therod 33 is disposed between theslide plates 60, and these left andright slide plates 60 are interconnected by a pin-shaped slideplate connecting member 52. The pin-shaped slideplate connecting member 52 is pivotably fitted in the left andright slide plates 60. The pin-shaped slideplate connecting member 52 is connected to therod 33 while permitting displacement of therod 33. The pin-shaped slideplate connecting member 52 is displaceable in interlocked relation to displacement of therod 33. - Because the two left and
right slide plates 60 are similar to each other in construction and operation, the following mainly describe the construction and operation of theright slide plate 60, omitting a detailed description about the construction and operation of theleft slide plate 60 to avoid unnecessary duplication. - The
slide plate 60 has a shape of a combination wrench. The pin-shaped slideplate connecting member 52 is inserted through aring section 61 of a generally circular hole shape formed in one end of theslide plate 60. Further, theslide plate 60 has amovable locking section 62 and a push-back portion 63 on the other end formed as an upwardly-opening section. Themovable locking section 62 is formed in a forwardly-oriented hooked shape for locking the front (first)engagement section 71, and the push-back portion 63 is formed in a curved shape and functions to abut against thefront engagement section 71 to move thebattery 16 rearward at the time of dismounting of thebattery 16 from themachine body 11 - Further, at the other end of the
slide plate 60 is formed aninsertion hole 60a through which thesecond shaft member 34 is inserted, so that theslide plate 60 is pivotable about thesecond shaft member 34. - From the foregoing, it can be said that the
rod 33 is pivotable at its upper end about thefirst shaft member 31 and pivotable at its connection with theslide plate 60 about thesecond shaft member 34. - Referring now to
Figs. 2 ,3 and5 , the left and rightfixed locking plates 38 are similar to each other in construction, operation and shape. The following mainly describe the construction and operation of the left fixed lockingplate 38, omitting a detailed description about the construction and operation of theright locking plate 38 to avoid unnecessary duplication. - The fixed
locking plate 38, which has a rearwardly-oriented hooked shape, includes the fixedlocking section 38a that locks the left rear (second)engagement section 75. Anupper end portion 38b of the lockingplate 38 is formed in a rearward downward slopes that is, theupper end portion 38b has an upper surface slanting rearwardly and downwardly. - As shown particularly in
Fig. 5 , thebattery 16 has: a disk-shaped large-diameter section 73 integrally formed on a leftside surface portion 161 of thebattery 16; ataper section 74 continuously tapering from the outer surface of the large-diameter section 73 outward in a width direction of thebattery 16; and the pin-shapedrear engagement section 75 integrally formed on and extending outwardly, in the width direction of thebattery 16, from the outer surface of thetaper section 74. - The right
rear engagement section 75 is similar in construction to the leftrear engagement section 75, as seen fromFig. 3 . Namely, thebattery 16 has: a disk-shaped large-diameter section 73 integrally formed on a rightside surface portion 16r; ataper section 74 continuously tapering from the outer surface of the large-diameter section 73; and the pin-shapedrear engagement section 75 integrally formed on and extending outwardly, in the width direction of themachine body 11, from the outer surface of thetaper section 74. - As shown in
Figs. 2 and3 , theguide member 39 of themachine body 11 includes left and right guidemember base sections 39a each having a generally L shape as viewed in side elevation of themachine body 11, and aguide section 39 extending in the width direction of themachine body 11 to interconnect the respective upper ends of the left and right guidemember base sections 39a. - As the human operator moves the
grip plate 43 in an up-down direction while holding thegrip plate 43, the L-shapedplate 41 pivots about thefirst shaft member 31 in the up-down direction, in response to which therod 33 moves in the front-rear and up-down directions. In response to such movement of therod 33, theslide plate 60 pivots about thesecond shaft member 34. - The following describe, with particular reference to
Figs. 6 to 9 , how thebattery 16 is mounted on the machine body 11 (in the mounting operation) and how thebattery 16 is dismounted from the machine body 11 (in the dismounting operation). - In the mounting operation, the human operator lowers the
battery 16 onto themachine body 11 in such an orientation that the width direction of thebattery 16 corresponds to the width direction of themachine body 11, and in such a manner that thefront engagement section 71 is located between themovable locking sections 62 and the push-back portions 63 of the left andright slide plates 60 as indicated by arrow, (1) inFigs. 6 and8(a) and that the left and right rear engagement sections 75 (only the leftrear engagement section 75 is shown in the figures) of thebattery 16 are lowered to be located behind the fixedlocking sections 38a of the left and right lockingplates 38. - Then, the human operator holds the
grip plate 43 so as to cause thegrip plate 43 to pivot upward as indicated by arrow (2) inFig. 7 , so that theslide plates 60 pivot as indicated by arrow (3) inFig. 7 and8(b) . Thus, themovable locking section 62 of each of theslide plates 60 abuts against thefront engagement section 71. - Then, the human operator further causes the
grip plate 43 to pivot in the direction of arrow (2) inFig. 7 , so that themovable locking sections 62 slides thebattery 16 from the placed position forward as indicated by arrow (4) while still locking thefront engagement section 71. Then, by the human operator further causing thegrip plate 43 to pivot in the direction of arrow (2), thebattery 16 can be slid to and fixed in the mounting position (seeFig. 2 ). - With the
battery 16 thus fixed in the mounting position, the rear surface and upper surface of thefront engagement section 71 is engaged by themovable locking sections 62, as particularly shown inFig. 8(c) , and the front and upper surfaces of the left and rightrear engagement sections 75 are engaged by the fixedlocking sections 38a of the left and right lockingplates 38. - Further, in the instant embodiment, a climb-over mechanism may be employed as appropriate in order to prevent the
grip plate 43 from pivoting in an opposite direction due to vibration caused during the operation of the machine. Namely, it is preferable that thegrip plate 43 be constructed to not pivot unless external force is intentionally applied to thegrip plate 43. The climb-over mechanism may be implemented by one well known in the art. - To dismount the
battery 16, the human operator causes thegrip plate 43 to pivot in a direction opposite the direction thegrip plate 43 was caused to pivot for mounting thebattery 16, as indicated by arrow (6) inFig. 2 . In response to such pivoting of thegrip plate 43 in the opposite direction, the push-back portion 63 of each of theslide plates 60 abuts against thefront engagement section 71 as shown inFig. 9(a) . - Then, as the human operator further causes the
grip plate 43 to pivot in the direction of arrow (6), the push-back portion 63 of each of theslide plates 60 pushes thefront engagement section 71 back rearward as indicated by arrow (10). Thus, thebattery 16 is moved rearward. Once thebattery 16 is moved back to a predetermined position, the human operator lifts up thebattery 16. - The instant embodiment of the present invention arranged in the above-described manner can achieve the following advantageous benefits.
- Referring to
Fig. 2 , themachine body 11 has the plurality of lockingsections battery 16 has the plurality ofengagement sections sections movable locking sections 62 can slide thebattery 16 to the predetermined mounting position while locking the front (first)engagement section 71. The fixedlocking sections 38a lock the left and right rear (second) engagement sections. Namely, thebattery 16 can be locked in the mounting position by the human operator operating the movable locking sections 62 (by means of the grip plate 43) provided on themachine body 11. That is, thebattery 16 can be fixed to themachine body 11 without a particular fastener, such as a bolt. - Besides, the
battery 16 can be locked in the predetermined mounting position by the human operator operating only the movable locking sections 62 (grip plate 43). Therefore, no tool has to be prepared at the time of the mounting of thebattery 16, and thus, thebattery 16 can be mounted on themachine body 11 with utmost ease. In this way, the instant embodiment allows thebattery 16 to be mounted on themachine body 11 with utmost ease without using any particular fastener, such as a bolt. - Further, at the time of dismounting of the
battery 16 from themachine body 11, the push-back portions 63 abut against thefront engagement section 71 and slides thefront engagement section 71 from the mounting position to a dismounting position where thebattery 16 can be dismounted from the mounting position (seeFig. 9(b) ). Then, the human operator can dismount thebattery 16 from themachine body 11 by lifting up thebattery 16 located in the dismounting position. In the dismounting operation of thebattery 16, it is not necessary for the human operator to slide thebattery 16 to the dismounting position. In this way, the instant embodiment allows thebattery 16 to be dismounted from themachine body 11 easily with a simple operation. - Various loads tend to be applied to the
machine body 11 from outside during operation of thesnow removal machine 10. Each of the fixedlocking sections 38a is formed in a hooked shape adapted to opposedly engage the corresponding one of the left and rightrear engagement sections 75 sliding toward the mounting position, and thus, even when a load has been input to themachine body 11, the instant embodiment can prevent excessive displacement of thebattery 16. - Further, the
spring 36 normally biases theslide unit 50 downwardly and normally biases therod 33 upwardly, and therod 33 is pivotably connected at its upper end to thehandle plate 40 and pivotably connected at its lower portion to theslide unit 50. To permit such pivotable connection, slight gaps are formed between therod 33 and thehandle plate 40 and between therod 33 and theslide unit 50. Due to vibration that can occur during the operation of thesnow removal machine 10, therod 33 may contact thehandle plate 40 and/or theslide unit 50, thereby causing unwanted noise sound. To avoid such noise sound, therod 33 is resiliently pressed by thespring 36 against thehand plate 40 with a predetermined force, but also theslide unit 50 is resiliently pressed by thespring 36 against therod 33 with a predetermined force. With such arrangements, the instant embodiment can reliably prevent noise sound from being generated between therod 33 and thehand plate 40 and theslide unit 50 due to vibration of themachine 10. - In placing the
battery 16 on themachine body 11, the human operator lowers thebattery 16 toward themachine body 11 while viewing the guide member 39 (guidesection 39b) from above, as seen inFig. 3 . At that time, the human operator places thebattery 16 in front of theguide member 39. Namely, theguide member 39 serves as a guide for positioning thebattery 16 in a predetermined position. Thus, with theguide member 39, thebattery 16 can be placed on the predetermined placed position of themachine body 11 where themovable locking sections 62 of the left andright slide plates 60 can lock thefront engagement section 71. Namely, with theguide member 39, the instant embodiment allows the human operator to readily recognize the predetermined position where thebattery 16 should be placed. - In placing the
battery 16 on themachine body 11, the human operator may sometimes lower thebattery 16 onto themachine body 11 in front of the predetermined position. In such a case, each of the left and rightrear engagement sections 75 abuts against theupper end portion 38b of the lockingplate 38 shown inFig. 8(a) . Theupper end portion 38b of the lockingplate 38 is formed in a rearward downward slope as noted above, and thus, as the human operator further lowers thebattery 16, thebattery 16 can be placed on the predetermined position by being guided rearward along the slopingupper end portion 38b of the lockingplate 38. - Further, as shown in
Figs. 3 and10(a) , the left and right left and right rear (or second)engagement sections 75 are integrally formed on and extending outwardly, in the battery width (left-right) direction, from the outer surfaces of thetaper sections 74 that are disposed inwardly of the corresponding left andright engagement sections 75 and continuously taper toward thecorresponding engagement sections 75. Thus, if thebattery 16 placed on themachine body 11 is deviated leftward from the predetermined position with theengagement section 75 spaced outwardly from the fixedlocking section 38a, the slanting surface of theleft taper section 74 abuts against the fixedlocking section 38a. - Then, as the
battery 16 is slid toward the mounting position, it is slid laterally toward the centerline (in the direction Ce) of themachine body 11 by the action of the slanting surface of theleft taper section 74 as depicted by arrow (20) inFig. 10(b) . Thus, thebattery 16 can be mounted on the predetermined mounting position. Similarly, if thebattery 16 placed on themachine body 11 is deviated rightward from the predetermined position, thebattery 16 can be slid laterally toward the centerline (in the direction Ce) of themachine body 11 by the action of the slanting surface of the right taper section 74 (seeFig. 3 ). In this way, thebattery 16 can be accurately mounted on the predetermined mounting position through a simple operation by the human operator, i.e. by the human operator operating only the movable locking sections 62 (seeFig. 2 ). - Whereas the mountable/dismountable-component mounting structure of the present invention has been described above as mounting the battery on the snow removal machine, the mountable/dismountable component to be mounted by the mounting structure of the present invention may be a gas tank or the like other than the battery. Further, the working machine on which the mountable/dismountable component is to be mounted by the mounting structure of the invention may be a lawn mower, a cultivating machine or the like other than the snow removal machine.
- It should be appreciated that the present invention is not limited to the above-described embodiment and may be modified variously as long as the intended operation and advantageous benefits can be attained.
- Finally, the mountable/dismountable-component mounting structure of the present invention is particularly well suited for application to mounting of batteries on snow removal machines.
- A structure for mounting a mountable/dismountable component (16) on a machine body (11) of a working machine (10) including: locking sections (38a, 62) provided on the machine body for locking the mountable/dismountable component; and engagement sections (71, 75) provided on the mountable/ dismountable component and engageable by respective ones of the locking sections (38a, 62). The locking sections include: a movable locking section (62) capable of sliding the mountable/dismountable component to a predetermined mounting position on the machine body while locking the first engagement section (71) of the engagement sections; and a fixed locking section (38a) constructed to lock a second engagement section (75), different from the first engagement section, of the engagement sections of the mountable/dismountable component in the predetermined mounting position.
