And then, the object to be stored is placed on the sliding bar. Therefore, the object on the bar can be pulled out from the inside of the storage rack, when the bar is slid from the inside. Then, an operator is able to take in and out the object in a storage rack.
- However, regarding the storage rack disclosed in Japanese Unexamined Utility Model Application, First Application No. S60-167550, when the object is slid with the sliding device, all weight of the object (i.e., a load of the object to be stored) is applied to the sliding device. Therefore, when a heavy object such as a secondary battery is stored, it has been difficult to stably support the object by the sliding device. For supporting the object stably, it is necessary to increase the rigidity of the sliding device. However, this is results in an increase in weight of the storage rack and a difficulty in maintenance. They are problem.
- The present invention has been made in view of the above problems, an object of which is to provide a storage rack which is simple in constitution and able to take out a heavy object such as a secondary battery placed on a shelf board.
- An aspect of the present invention is a storage rack for setting an object to be stored (hereinafter referred as “the storage rack of the present invention”) comprising: a shelf board where the object is placed and which is able to slide in a horizontal direction from a rear side of a rack main body to an outside of the rack main body toward a front side of the rack main body; a supporting structure supporting the shelf board by moving together with the shelf board when the shelf board is slid.
- With the storage rack of the present invention, a heavy object can be moved out from the storage rack (i.e., a rack main body) easily by pulling out and sliding the shelf board even if an object, which is a heavy object such as a secondary battery, is placed on the shelf board. Generally, when a shelf board on which an object to be stored has been placed is pulled out, the pulled-out shelf board is held like a cantilever. It means that the shelf board is supported only at the base end in the pulled-out direction. As a result, supporting of the pulled-out shelf board becomes unstable.
- Because the storage rack of the present invention has a supporting structure, a movement of which is coupled with the sliding movement of the shelf board, the supporting structure is able to support the shelf board which has been pulled out from the storage rack. Thereby, even when a heavy object is placed on the shelf board, it is possible to stably support the pulled-out shelf board. Further, as described above, because the shelf board can be stably supported by the supporting structure, supporting the shelf board by moving together with the shelf board, it is possible to simplify a structure of a slide guide, which slidably supports the shelf board at side ends of the shelf board and a structure of the shelf board, which directly supports the object to be stored.
- With the storage rack of the present invention, the object to be stored can be pulled out in a state where the object is stably supported on a shelf board even if the object is a heavy object such as a secondary battery.

FIGS. 1 to 8 . -
FIG. 1 illustrates amovable battery unit 100 including a plurality of batteries. - As shown in
FIG. 1 , thebattery unit 100 includes box-shaped container 2, a pair ofstorage racks container 2, and a plurality ofbatteries 1 on thestorage racks batteries 1 are examples as objects to be stored. Thebattery 1 is not limited to any particular type. For example, if may be a secondary battery or a fuel cell. Here, directional axes used in the following description will be defined as follows. An X axis direction, a Y axis direction and a Z axis direction are there is enough space respectively given as a width direction T2 of the storage rack, a depth direction T3 of the storage rack, and a vertical direction T1 of the storage rack. - In the present embodiment, the pair of storage racks 10, 11 inside the
container 2 are installed together along the longitudinal direction of thecontainer 2, there is enough space between the storage racks. The space between the pair of storage racks 10, 11 forms anaisle 3 which is wide enough for an operator to pass through. - As shown in
FIGS. 1 and 2 , each of the storage racks 10, 11 includes the a frame (i.e., rack main body) 4 fixed on the floor surface of thecontainer 2, a plurality ofshelf boards 5 attached to theframe 4 in a multiple stage at predetermined intervals in a vertical direction T1, and aslide guide 6 for supporting theshelf board 5 and for being slidable with respect to theframe 4. The plurality ofshelf boards 5 are installed at each of the stages along a horizontal direction T2 which is the width direction of the storage racks 10, 11 (i.e., rack main bodies). Aside wall 7 attached to theframe 4 is also installed on both side end sides of each of theshelf boards 5. - Further, the slide guides 6 are extended in a horizontal direction T3 which is the depth direction of each of the storage racks 10, 11 and installed to make a pair corresponding to each of the
shelf boards 5. Then, each of theshelf boards 5 is supported at the both side ends thereof by the corresponding pair of slide guides 6 in order to slidably move in the horizontal direction T3. - Then, as shown in
FIG. 3 , each of theshelf boards 5 is installed that is guided by the slide guides 6 and slidably move from a corresponding storage rack between the storage racks 10, 11 to theaisle 3 side that can be pulled outward in the horizontal direction T3 from the storage racks 10, 11. - In the storage racks 10, 11 of the present embodiment configured as explained above, two of the
batteries 1 are arrange and placed on theshelf boards 5 along the horizontal direction T3 as shown inFIGS. 1 to 3 . Further, the pair ofbatteries 1 placed on thesame shelf board 5 are electrically connected by a plate-shaped bus bar which is Figures. Still further, the pairs ofbatteries 1 placed ondifferent shelf boards 5 are electrically connected. For example, they are connected by a freely extendable cable formed in a helical shape which is Figures. Thus, the plurality ofbatteries 1 is connected in series or in parallel, to form assemble batteries. - Then, as shown in
FIG. 3 , in the storage racks 10, 11 of the present embodiment, theshelf boards 5 is guided by the the pair of slide guides 6 and is able to be pulled out to theaisle 3 side. Thebatteries 1 placed on theshelf boards 5 can be taken out from the corresponding storage rack at position where is on theaisle 3. - At this time, because the cable is formed to be freely extendable, irrespective of a change in the relative position of the
batteries 1 belonging to twodifferent shelf boards 5, thebatteries 1 placed on each of theshelf boards 5 can be taken out from the storage racks 10, 11 without removing the cable. - Here, the plurality of
batteries 1 placed on ashelf board 5 is heavy objects. Therefore, when theshelf board 5 is simply slid and be pulled out theaisle 3, theshelf board 5 become like cantilever and is unstable. As a result, it is difficult to replace thebatteries 1, and to do scheduled maintenance or the like. - On the other hand, in the storage racks 10, 11 of the present embodiment, as shown in
FIG. 4 andFIG. 5 , a supportingstructure 8 move with the shelf board sliding along with the slidguide 6. The supportingstructure 8 is installed on each of theshelf boards 5. Ahandle 9 is fixed on theshelf board 5. Therefore an operator can grip thehandle 9, and control to make theshelf board 5 slidably moved along theaisle 3. - The supporting
structure 8 of the storage rack of the present embodiment include aguide part 15 formed at one side end of the rackmain body 4, a rod-shaped supportingpart 16 for supporting theshelf board 5 that is able to slidably move along the slide guides 6, and anoperation part 17 for operating the supportingpart 16. - The
guide part 15 includes a guide groove which is recessed to an outer surface side from an inner surface of one of theside walls 7. Theguide groove 15 is formed from arear end 7 a side in the depth direction T3 of one of the side walls 7 (i.e., approximately at the middle on the rear side of the rack main body) to afront end 7 b (i.e., to the front side of the rack main body). The guide groove ascends gradually from therear end 7 a side in the depth direction T3 to thefront end 7 b. Further, the fitting recessedsites surface 15 a of the guide groove. The upward facingsurface 15 a is a side of guide groove with faces upward. These fitting recessedsites - Then, the guide groove (i.e., a guide part) 15 of the storage shelf of the present embodiment includes a first fitting recessed
site 18 at the lowest end and, a second lowest fitting recessedsite 19, and a third lowest fitting recessedsite 20 between the lower end and the upper end, with a predetermined interval. - The supporting
part 16 includes a supportingrod 16 a, the upper end side of which is pivotably connected to one side end of theshelf board 5, and afitting body 16 b which is a connect shape, formed installed integrally at the lower end side of the supportingrod 16 a, and which is able to be fitted into or caught by the fitting recessedsites guide groove 15. - The upper end side of the supporting
rod 16 a is pivotably connected to one side end of theshelf board 5 with afirst hinge 21. Therefore, the supportingrod 16 a is allowed to turn along the inner surface of one of theside walls 7 with respect to theshelf board 5. Further, the position of thefirst hinge 21 is placed between theguide groove 15 and the front end of thestorage rack 10 horizontally in T3 direction inFIG. 4 , when theshelf board 5 is pushed in (i.e., when theshelf board 5 is completely housed in the rack main body, and thefitting body 16 b is caught by the first fitting recessed site 18). - The
fitting body 16 b is formed to project outside in a direction perpendicular to the axis of the supportingrod 16 a (i.e., approximately the inner surface side of one of the side walls 7). Further, thefitting body 16 b is formed in a cylindrical shape. One end thefitting body 16 b is a inserted and engaged into the guide groove. - The
operation part 17 includes alever member 23, which is pivotably connected to the front part of one side end of theshelf board 5 in the depth direction T3 with asecond hinge 22, and a pressingmember 25 which is pivotably connected to the front part of one side end of theshelf board 5 in the depth direction T3 with athird hinge 24. - The
lever member 23 is formed substantially in a rod shape and extends to both sides horizontally from thesecond hinge 22. - The
lever member 23 has two portions. A portion closer to the front end of the rackmain body 4 is alever part 23 a. Thelever part 23 a is able to be turned by an operator's hand. Another portion closer to the rear end of the rackmain body 4 is apressing part 23 b. - The pressing
member 25 is formed substantially in an L-shaped and pivotably connected to one side end of theshelf board 5 with thethird hinge 24. Thethird hinge 24 is arranged between thefirst hinge 21 and thesecond hinge 22 in the depth direction 13. Similar to thelever member 23, the pressingmember 25 has two portions. Instead of the location of thesecond hinge 22, thethird hinge 24 defines the boundary of the two portions. Another portion closer to the front end of the rackmain body 4 is alever pressing part 25 a. A portion closer to the rear end of the rackmain body 4 is a supportingrod pressing part 25 b. Thelever pressing part 25 a is placed below to and near thepressing part 23 b of thelever member 23. The supportingrod pressing part 25 b is placed close to the supportingrod 16 a and on the front side of the supportingrod 16 a. - In the storage racks 10, 11 of the present embodiment, there are included the above-constituted supporting
structure 8 as shown inFIG. 4 . When thebatteries 1 are placed on theshelf board 5 which is arranged inside theframe 4, thefitting body 16 b is fitted into the first fitting recessedsite 18 of theguide groove 15. As shown inFIG. 6 , when thebatteries 1 are tried to be replaced, during the maintenance, theshelf board 5 on which thebatteries 1 are placed is pulled out from theframe 4. When the shelf boards is being pulled out the supportingrod 16 a is moved together according to the movement of theshelf board 5, by pivoting at thefirst hinge 21, and thefitting body 16 b comes out or escapes from the first fitting recessedsite 18. When theshelf board 5 is pulled out further from theframe 4, thefitting body 16 b moves toward the front end of the storage racks 10, 11 along theguide groove 15. - Then, when the
fitting body 16 b reaches to the second fitting recessedsite 19, the supportingrod 16 a and thefitting body 16 b pivot at thefirst hinge 21 due to their own weight, and thefitting body 16 b is trapped and caught by the second fitting recessedsite 19. Thereby, theshelf board 5 is supported by the supportingrod 16 a, because the upper end of the supportingrod 16 is connected to theshelf board 5 and the lower-end sidefitting body 16 b is fitted into and caught by the second fitting recessedsite 19. Thus, even when the heavy batteries (i.e., objects to be stored) 1 are placed on theshelf board 5, the loads are received by the supportingrod 16 a and transferred through thefitting body 16 b and theguide groove 15 to theside wall 7 and theframe 4. It is, thereby, possible to support thebatteries 1 in a stable state. - Then, when the
shelf board 5 is further instead to be pulled out from theframe 4, as shown inFIG. 7 , an operator manually raises thelever part 23 a of thelever member 23 at theoperation part 17. This action allows thelever member 23 to turn on thesecond hinge 22. Because thelever member 23 is operated as described above, thepressing part 23 b of thelever member 23 presses thelever pressing part 25 a of the pressingmember 25 downward. Therefore, the pressingmember 25 turns on direction by thethird hinge 24, the supportingrod pressing part 25 b of the pressingmember 25 presses the supportingrod 16 a upward, consequently the supportingrod 16 a turns on thefirst hinge 21 and thefitting body 16 b comes out or escapes from the second fitting recessedsite 19. Therefore, an operator is able to pull theshelf board 5 out by using thehandle 9. In addition, thefitting body 16 b is guided by theguide groove 15 and moves further forward and upward. - Then, as shown in
FIG. 8 , when theshelf board 5 is further pulled out theaisle 3, thefitting body 16 b is trapped and caught by the third fitting recessedsite 20. Therefore, theshelf board 5 is supported by the supportingrod 16 a, because the upper end side of the supportingrod 16 a is connected to theshelf board 5 and the lower-end sidefitting body 16 b is fitted into the third fitting recessedsite 20. In addition, even when theheavy batteries 1 are placed on theshelf board 5, the loads are received by the supportingrod 16 a and transferred through thefitting body 16 b and theguide groove 15 to theside wall 7 and theframe 4. Therefore, it is possible to support thebatteries 1 stably. Thereby, the replacement of thebatteries 1 and its maintenance can be suitably carried out. - After that, when an operator intend to insert the
shelf board 5 inside theframe 4, the operator manually raises thelever member 23 of theoperation part 17, and presses theshelf board 5 inside. Therefore, thefitting body 16 b is guided by theguide groove 15 and moves backward and downward. In the meantime, theshelf board 5 slidably moves inside the storage racks 10, 11 and is duly stored. - Therefore, according to the storage racks 10, 11 of the present embodiment, the object to be stored 1 can be easily moved out from the storage racks 10, 11 by pulling out the
shelf board 5, even if the object is a heavy object such as a secondary battery. - Furthermore, the object to be stored 1 can be pulled out in a state where the object is stably supported on a
shelf board 5 even if the object is a heavy object such as a secondary battery, since theshelf board 5 is provided with the supportingstructure 8, a movement of which is coupled with the sliding movement of theshelf board 5 to support theshelf board 5. Still further, since theshelf board 5 can be stably supported by the supportingstructure 8, a movement of which is coupled with the movement of theshelf board 5, it is possible to simplify a structure of aslide guide 6, which slidably supports the shelf board at side edges of the shelf board and a structure of theshelf board 5, which directly supports the object to be stored 1. - Further, when the
shelf board 5 is allowed to slidably move, the supportingpart 16, the upper end of which is pivotably connected to the side edge of theshelf board 5, pivots. Then, thefitting body 16 b at the lower end side of the supportingpart 16 moves inside theguide groove 15 and is trapped in the fitting recessedsites shelf board 5 can be received and supported by the supportingpart 16. Even when the heavy objects to be stored 1 are placed on theshelf board 5, it is possible to stably support (retain) the pulled-outshelf board 5. - Furthermore, by turning the
lever member 23 of theoperation part 15, the supportingpart 16 can be pressed to be pivoted. Thus, thefitting body 16 b can be easily released from the entrapped state in the fitting recessedsites lever member 23 to pull out thefitting body 16 b from the fitting recessedsites shelf board 5 can make a sliding movement by letting thefitting body 16 b moving along theguide groove 15. - Thus, by using the storage racks 10, 11 of the present invention, fast and flexible response can be made in replacement and maintenance operations of the
batteries 1, since the pulled-outshelf board 5 is stably supported and each of thebatteries 1 can be easily accessed with an operator in a case where a large number of thebatteries 1 are set inside thecontainer 2 and used by being placed on theshelf board 5. - The first embodiment of the storage rack of the present invention is explained above. However, the storage rack of the present invention shall not be limited to the above-described first embodiment. The storage rack of the present invention may be changed whenever necessary within a scope not departing from the gist of the present invention.
- For example, in the present embodiment, the three fitting recessed
sites guide groove 15. However, the fitting recessed sites are not in particular limited to the number and the position thereof. - Further, as shown in
FIG. 9 , an intersecting angle θ formed between a surface of the fitting recessedsites shelf board 5 is pulled out from the storage racks 10, 11, it is possible to reduce force necessary for releasing thefitting body 16 b from the fitting recessedsites - Further, in the present embodiment, as to the supporting
structure 8 ofstorage racks lever part 23 a of thelever member 23 at theoperation part 17, and the supportingrod 16 a of supportingpart 16 to pivot and then the operator separately pulls and pushes thehandle 9 to take in and out theshelf board 5. - However, the supporting
structure 8 ofstorage racks lever member 23 to work together with the supportingrod 16 a when an operator grips thehandle 9. More specifically, for example, as shown inFIGS. 10 and 11 , thehandle 9 is extended along the width direction T2 and connected to leverpart 23 a of thelever member 23 and a turningshaft 26 of theshelf board 5. According to this structure, when an operator grips and raises thehandle 9, thehandle 9 pivots the turningshaft 26 and thesecond hinge 22. At this time thelever member 23 work together. Therefore, it is possible to move, the supportingrod 16 a upward. Further, an operator is able to pull and push thehandle 9 while gripping and raising thehandle 9, for taking in and out theshelf board 5. It is possible to take in and out theshelf board 5 more easily than the present embodiment and also increase the usability. - In the present embodiment, a description has been given on the assumption that the storage racks 10, 11 are installed inside the
container 2 and used for storing thebatteries 1 such as secondary batteries. However, the storage rack of the present invention shall not be limited to the use of storing thebatteries 1 and is, of course, applicable to any and all places for storing (placing) any objects to be stored. - Next, a description will be given of the storage rack of the second embodiment of the present invention with reference to
FIG. 12 toFIG. 15B . The present embodiment is different from the first embodiment only about the supporting structure. Therefore, in the present embodiment, the same reference numerals will be given to the same structures as those of the first embodiment, and a detailed description omitted. - As shown in
FIG. 12 andFIG. 13 , a supportingstructure 30 of the present embodiment includes guidepart 31 which is a substantially cylindrical rod-shaped, a substantially tubular linkingpart 32, and a rod-shaped supportingpart 34. Both end of theguide part 31 are fixed to one ofside walls 7 or theframe 4 of each of the storage racks 10. 11. Theguide part 31 is inserted into the linkingpart 32, and the linkingpart 32 is guided by theguide part 31 and allowed to move forward and backward along theguide part 31. Further, the linkingpart 32 is fixable to theguide part 31. One end of the supportingpart 34 is connected to one side end of theshelf board 5 in order to pivot on afirst hinge 33. Another end of the supportingpart 4 is pivotably connected to the linkingpart 32. Therefore theshelf board 5 is able to slidably move along slide guides 6. - One end of
guide part 31 of the present embodiment is fixed in front of the other end itself and the one end is in the depth direction T3. - The linking
part 32 is formed into a substantially tubular tube shape. The linkingpart 32 has two portions has that are formed by cutting the tubular tube to blocks along the axis line. The two blocks (i.e., theblock 32 a and theblock 32 b) are coupled with anelastic member 32 c to form a substantially tubular shape. Then, the linkingpart 32 is attached in such a manner that theguide part 31 is inserted through an inner hole formed by theblock 32 a and theblock 32 b. As a result, theguide part 31 is retained by theblock 32 a and theblock 32 b on theguide part 31. - In the linking
part 32, the lower end of the supportingpart 34 is connected to theblock 32 a in order to pivot on asecond hinge 35. When an operator lifts ashelf board 5, the linkingpart 32 can be released and become to move as shown inFIGS. 15A and 15B . When the operator stops lifting theshelf board 5, a force is generated for one dividedblock 32 a to move closer to the other dividedblock 32 b due to the loads transferred from the supportingpart 34. Therefore, theguide part 31 is clamped and retained by both of theblocks - In addition, in the present embodiment, as shown in
FIG. 15A , a cross section of aninner surface 32 d of theblock 32 a in the plane parallel to the directions T1 and T2 is formed in L-shape or bended-shape. When the linkingpart 32 is locked on theguide part 31 as shown inFIG. 15A , the upper half portion of theinner surface 32 d aligns parallel to the outer surface of theguide part 31 and is pressed and contacted to the surface that is parallel to theouter surface 32 e of theblock 32 a. On the other hand, the lower half portion of theinner surface 32 d is formed with a gradual inclination toward theouter surface 32 e, increasing the diameter of the inner hole of the linkingpart 32 downward. In addition, the upper end portion of theblock 32 a, and the lower end part of the supportingpart 34 is pivotably connected to the upper part end portion of theblock 32 a with thesecond hinge 35. - As shown in
FIG. 15A , as to the linkingpart 32, theguide part 31 is clamped and retained by both the upper end of theblock 32 a and theinner surface 32 d of theother block 32 b. On the other hand, as shown inFIG. 15B , when the supportingpart 34 is allowed to pivot on thefirst hinge 33, the upper end side of theblock 32 a is detached from theguide part 3 the upper-end sideinner surface 32 d of theblock 32 is able to move from the outer surface of theguide part 31. Therefore, the linkingpart 32 is released from theguide part 31. At this time, the lower-end sideinner surface 32 d of theblock 32 a moves closer to the outer surface of theguide part 31. - In the storage racks 10, 11 of the present embodiment, as shown in
FIG. 14 , when an operator lifts theshelf board 5 and pulls thehandle 9, theshelf board 5, on which thebatteries 1 are placed, is able to be pulled out from the storage racks 10, 11. When theshelf board 5 is pulled out from the storage racks 10, 11, the upper end side of the supportingpart 34 is pulled together with theshelf board 5. As described above, when the supportingpart 34 is pulled, theblock 32 a of the linkingpart 32 moves to increase the diameter of the inner hole of the linkingpart 32. Thereby, state of the linkingpart 32 is released and the linkingpart 32 is guided by theguide part 31 and is able to move upward. - Then, when an operator pulls out the
shelf board 5 to a desired position and stops the sliding movement of theshelf board 5, the supportingpart 34 and theblock 32 a of the linkingpart 32 are no longer pulled. As a result, the diameter of the inner hole of the linkingpart 32 is reduced, and the linkingpart 32 is locked on theguide part 31. Consequently, loads of theshelf board 5 are received by the supportingpart 34 and guidepart 31, even if theshelf board 5, on which theheavy batteries 1 are placed, is pulled out in an intended distance and theshelf board 5 is stably supported. - On the other hand, when the
shelf board 5 is stored and inserted in the storage racks 10, 11, an operator lifts theshelf board 5 and presses t theshelf board 5 slidably to the storage racks 10, 11. Thereby, while turning by thefirst hinge 33, the upper end side of the supportingpart 34 is pressed inside together with theshelf board 5. Then, as described above, the upper end side of the supportingpart 34 is pressed inside, by which the lower end side of the supportingpart 34 is pressed downward while being turned by thesecond hinge 35. - Further, when an operator stores the
shelf board 5 into the storage racks 10,11 and inside to stop the sliding movement, one dividedblock 32 a undergoes displacement so as to move closer to the other dividedblock 32 b due to the restoring force of theelastic member 32 c and due to the loads derived from the supportingpart 34. Therefore, the inner hole of the linkingpart 32 is reduced in diameter. Thereby, the linkingpart 32 is locked and fixed to theguide part 31. The loads of theshelf board 5 are received by the supportingpart 34 and theguide part 31, by which theshelf board 5 is supported in a stable state and stored in the storage racks 10, 11. - Therefore, even when heavy objects such as secondary batteries are placed on the
shelf board 5, by pulling out theshelf board 5, the objects can be taken out easily from the storage racks 10, 11. - Further, each of the storage racks 10, 11 of the present embodiment includes the supporting
structure 30, a movement of which is coupled with the sliding movement of theshelf board 5 to support theshelf board 5. Therefore, even when the heavy objects are placed on theshelf board 5, it is possible to stably support the pulled-outshelf board 5. Still further, because theshelf board 5 can be stably supported by the supportingstructure 30, it is possible to simplify a structure of theslide guide 6 which supports at the base end theshelf board 5 or a structure of theshelf board 5 which directly supports the objects to be stored 1. - In addition, in the storage racks 10, 11 of the present embodiment, when the
shelf board 5 is allowed to slidably move, the supportingpart 34 turns, the upper end side of which is connected to one side end of theshelf board 5 so as to turn. Thereby, the linkingpart 32 connected to the lower end side of the supportingpart 34 is allowed to move forward and backward along theguide part 31. Then, upon stop of the sliding movement of theshelf board 5, the linkingpart 32 is fixed to theguide part 31. Thereby, loads of the pulled-outshelf board 5 can be received and supported from the supportingpart 34 to the linkingpart 32 and from the linkingpart 32 to theguide part 31. Thus, even when the heavy objects are placed on theshelf board 5, it is possible to stably support the pulled-outshelf board 5. - Further, the supporting
structure 30 is able to support and retain theshelf board 5 which has been pulled out to a desired position, without any restriction on a pulled-out amount of theshelf board 5. Still further, the supporting rod of the second embodiment is smoother in motion and better in operating performance than that of the first embodiment. - Thus, when a large number of the
