[Prior Art] As a seat cushion opening / closing mechanism of a locomotive, for example, a structure described in a conventionally disclosed in "2001's seat cushion of a Sukoda vehicle" is known. The second diagram of the above publication will be described below with reference to FIG. 25. Figure New labeling. FIG. 25 is a perspective view showing a conventional seat cushion opening and closing structure. The front part of the box 3 0 1 is a seat cushion 303 that can be opened and closed freely through a seat cushion hinge 3 2. A first door is installed on the bottom surface of the seat cushion 303. In order to support the first door-shaped fitting 3 0 5, a first seat cushion locking mechanism 3 0 6 is arranged on the side of the storage box 3 0 1 to support the first door-shaped fitting 3 0, and the second Π-shaped fitting 3 0 5 and a seat cushion locking mechanism 3 07 is arranged at the rear of the storage box 3 01, describing the seat cushion opening and closing structure thus constituted. [Summary of the Invention] [Problems to be Solved by the Invention] As described above, a first seat cushion lock is provided. The mechanism 3 0 6 and the pad locking mechanism 3 07 can prevent the large seat cushion 3 0 3 from being opened, and if the number of the locking mechanism can be made one, it is heavier than the Japanese special structure number of the car body. Pieces 3 04 3 04 and can be arbitrarily supported in order to support the second and second seat. -5- (2) (2) 200401728 Reduces the cost of the part itself and the installation cost, and does not need to be used to connect the first seat cushion locking mechanism 3 06 with the second seat cushion locking mechanism 3 07 the second cable 3 0 8 can also be In order to reduce the cost of steel cables. An object of the present invention is to improve the seat cushion opening and closing structure of a locomotive, and in particular, for a locomotive provided with a large-sized seat cushion, the seat cushion locking mechanism, that is, the seat cushion buckle, can be reduced to one. [Means for solving the problem] The first invention for achieving the above-mentioned object is to provide an article storage box under the seat cushion, and the seat cushion can be opened and closed freely through seat cushion hinges provided on the left and right sides of the seat cushion. The seat cushion opening / closing structure of the locomotive tilts the hinge shaft so that the front portion approaches forward and downward from the side and the front portion approaches from the top toward the inside of the vehicle body. When the seat cushion is closed, the seat cushion bottom plate is made. The convex portion provided on the front portion is engaged with the concave portion provided on the front portion of the article storage box. In the past, in order to prevent theft due to deformation of the seat cushion, when the seat cushion is closed, a seat cushion buckle that engages the seat cushion on the side of the vehicle body is installed at two positions. In the present invention, The engagement of the article storage box and the seat cushion is performed by the concave portion on the article storage side and the convex portion on the seat cushion side, so a seat cushion buckle can be saved, which can maintain the anti-theft function and reduce cost. The second invention is to pass the hinge shaft through the vicinity of the lower portion of the engaging portion. By passing the hinge shaft near the lower part of the engaging portion, the seat cushion is closed and the recessed portion on the storage box side and the convex portion on the seat cushion are engaged with each other, even if an upward force is applied to the seat cushion If you want to open the seat cushion, the seat-6-(3) (3) 200401728 is also difficult to rotate around the hinge axis, and the seat cushion is difficult to open, which can improve the anti-theft effect. According to a third invention, a recessed portion is formed in an opening flange portion of an upper portion of the article storage box. Since the recessed portion is formed at the opening flange portion of the upper portion of the article storage box, the shape change of the article storage box forming the recessed portion can be reduced compared to the case where the recessed portion is specially made, and the cost can be reduced. The flange portion is a rigid portion of the upper edge portion of the article storage box. Therefore, by providing the recessed portion to the flange portion having higher rigidity, even when external force acts on the recessed portion via the convex portion on the seat cushion side, It is also possible to suppress deformation of the concave portion.

(18) (18)200401728 與特別形成凹部的方式相比，可以減少用來形成凹部1 84 的置物箱22的形狀變更，能夠抑制成本。 凸緣部8 3，是用來提高置物箱2 2的上部緣部的剛性 的部份，藉由在該高剛性的凸緣部83設置凹部1 84 ’則 在外力經由凸部1 8 6作用在凹部1 8 4時，能夠抑制凹部 184的變形。而會更難打開雙人座墊23。 第1 7圖是用來說明本發明的置物箱內的分隔部的立 體圖，是顯示設置有***在置物箱22內能夠變更位置的 一片分隔板2 1 1 ◦省略了舖設於置物箱22內的地毯部（ 後面會詳細敘述）。 分隔板2 1 1，是可更換到：設置在置物箱22內的前 部的前部分隔板***部2 1 2、與設置在置物箱2 2內的中 間部的中間部分隔板***部2 1 3。當不分隔置物箱22時 ，則使分隔板2 1 1沿著置物箱2 2的背面2 1 4。 第1 8圖是本發明的置物箱的剖面圖，在置物箱2 2內 ，是舖設有沿著置物箱2 2的內部形狀的底盤狀的地毯部 22 1，且以中間部分隔板***部2 1 3來分隔置物箱22內。 地毯部22 1，是用來保護收容物不受到損傷。 不用來分隔置物箱22內的分隔板2 1 1，是***到置 物箱2 2的背面2 1 4與地毯部2 2 1的後壁2 2 2之間。2 2 4 是置物箱22的前部底面，226是置物箱22的中間部及後 部的底面也就是中後部底面。地毯部2 2 1的形狀後面會詳 細敘述。 第1 9圖是本發明的置物箱的前部及中間部的平面圖 -22- (19) 200401728 (圖中的箭頭（左）表示車體左方，箭頭（ 右方。以下相同。），爲了***分隔板21 圖），在置物箱22的前部底面224及左右 2 3 1的前部形成***部2 3 3、2 3 4，在中後部 ***溝2 3 6及***部2 3 7，在側壁2 2 8、2 3 別形成***溝2 3 8、241。也就是說，***部 構成前部分隔板***部2 1 2的部份，***溝 23 7、及***溝23 8、241是構成中間部分隔 的部份。 第20圖（a) 、（ b)是用來說明本發 入部的剖面圖，（a )是第1 8圖的 A- A竊 )是第1 8圖的B — B線剖面圖。 (a )圖是顯示著前部分隔板***部2 : 面2 24與側壁228前後並排地形成了 L字型 、245 (僅圖不其中一*個 L字壁245)，在 與側壁2 3 1前後並排地形成了 L字型的L ^ (僅圖示其中一個L字壁246)，將L字壁 以及L字壁24 6、246間作爲用來***分隔 第18圖）的***溝247、248。 (b )圖則是顯示中間部分隔板***部 部底面226的左端形成***溝23 6，在中後j 右端是前後並排地形成了橫方向較長且大致 251、251(僅圖示其中一個矩形壁251)， 、2 5 1之間作爲用來***分隔壁2 1 1 (參照· 右）表示車體 1 (參照第18 的側壁228、 底面226形成 1的中間部分 233 、 234 是 2 3 6、***部 板***部2 1 3 明的分隔板插 ^剖面圖，（b 1 2，在前部底 的L字壁2 4 5 前部底面224 P Μ 246 、 246 245 、 245 間 壁2 1 1 (參照 2 1 3，在中後 部底面2 2 6的 矩形的矩形壁 將矩形壁2 5 1 ;18圖）的插 -23- (20) (20)200401728 入溝2 5 2，在側壁2 2 8的傾斜部份形成***溝2 3 8，在側 壁2 3 1的傾斜部份形成***溝2 4 1。 第2 1圖（a )、（ b )是顯示本發明的***到分隔板 ***邰的分隔板的剖面圖，（a )是前部分隔板***部的 剖面圖（對應第2 0圖（a ) ) ， （ b )是中間部分隔板插 入部的剖面圖（對應於第20圖（b ))。 在（a )圖中，分隔板2 1 1，是作成大致四角形狀的 構件，是具備有：大致直線狀且寬度爲W1的第一邊部 255、與該第一邊部255相對向的邊部，且寬度較第一邊 部255的寬度W1更小的寬度爲W2的第二邊部256、以 及分別連接者弟一^邊部2 5 5及第二邊部2 5 6的各個端部的 第三邊部257及第四邊部258。在第三邊部257具有傾斜 部2 6 1，在第四邊部2 5 8具有傾斜部2 6 2。 在前部分隔板***部212，是在***溝2U、248插 入分隔板2 1 1的第一邊部2 5 5、第三邊部2 5 7的端部以及 第四邊部2 5 8的端部。 在（b )圖中，在中間部分隔板***部2〗3中，在插 入溝236及***溝252，***分隔壁211的第二邊部256 ，並且在***溝238***第三邊部257的傾斜部261，在 ***溝2 4 1***弟四邊部2 5 8的傾斜部2 6 2。 如以上的（a ) 、（ b )圖所示，在本發明中，是使分 隔板2 1 1的第一邊部2 5 5的形狀沿著前部分隔板***部 2 1 2的前部底面2 2 4的形狀，並且使第一邊部2 5 5的寬度 W 1大致配合前部分隔板***部2 1 2的側壁2 2 8與側壁 -24- (21) (21)200401728 2 3 1的間隔，是使分隔板2 1 1的第二邊部2 5 6的形狀沿著 中間部分隔板***部2 1 3的中後部底面226的形狀，並且 使第二邊部2 5 6的寬度W2大致配合中間部分隔板***部 2 1 3的側壁2 2 8與側壁2 3 1的間隔。 第22圖（a) 、 （b)是本發明的地毯部的立體圖， (a )是顯示摺疊前的狀態的立體圖，（b )是顯示經過摺 疊後的狀態的立體圖。 在（a)圖中，地毯部221，是由：底部265、從該底 部2 6 5立起的側壁2 6 6、2 6 7及上述的後壁2 2 2所構成， 在側壁266、267及底部2 6 5，是設置有容易進行摺疊的 細縫部2 7 1、2 7 2。 細縫部2 7 1、2 7 2，如第2 1圖（a )所示也有使L字 壁245、245及L字壁246、246露出於外部的部份。274 、2 7 6是用來使***溝2 3 6、2 3 8分別露出於外部的設置 於側壁266的開口部。用來使***溝2 5 2、241露出於外 部的開口部設置於側壁267則沒有圖示出來。 在（b )圖中，是顯示從地毯部2 2 1的細縫部2 7 1、 2 7 2開始，將前側的地毯部前部2 7 7進行摺疊的狀態。藉 由將地毯部22 1作成可摺疊，則能夠提昇當將髒東西與其 他東西分開收容時的使用方便性。 第23圖（a )、（ b )是顯示本發明的置物箱的使用 例的作用圖，（a )是顯示沒有使用分隔板的狀態的作用 圖，（b )是顯示將分隔板***到前部分隔板***部的狀 態的作用圖。 -25- (22) (22)200401728 在（a )圖中，當在置物箱22內，例如收容著大型的 皮箱及中型的安全帽2 8 2等的較大的東西時，則不使用分 隔板2 1 1。 在（b )圖中，當在置物箱2 2內，例如收容著手套 283等的小東西、與較大的皮箱284、與大型的安全帽 2 8 6時’則將分隔板2丨丨***在前部分隔板***部2丨2， 將手套2 83收容在分隔板2 i〗的前方的空間s 1，在分隔 板2 1 1的後方的較大的空間s 2收容皮箱2 8 4與安全帽 286 ° 第24圖（a )、（ b )是顯示本發明的置物箱的其他 使用例的作用圖，（a )是顯示將分隔板***在中間部分 隔板***部的狀態的作用圖，（b )是顯示將地毯部部的 前邰摺疊’且將分隔板***到前部分隔板***部的狀態的 作用圖。 在（a)圖中’當在置物箱22內收容較大的東西，例 如分開收容中型的安全帽2 8 2與大型的安全帽2 8 6時，將 分隔板2 1 1***到中間部分隔板***部2 i 3，將安全帽 2 82收容在分隔板211的前方的空間s3，在分隔板211的 後方的空間S 4 (較分隔板2 1 1的前方的空間s 3更大）收 容安全帽2 8 6。 在（b )圖中，當在置物箱22內收容髒東西例如由鏈 條或鋼索所構成的車輪鎖定裝置2 8 7等時，會將地毯部 221的地毯部前部277加以摺疊然後將分隔板211***到 則部分隔板***邰2 1 2，在分隔板2 1 1的前方的空間$ 1 -26- (23) (23)200401728 收容車輪鎖定裝置2 8 7。 將地毯部22 1加以摺疊而在分隔板2 1 1的前方的空間 收容髒東西的話，即使容易弄髒該收容部份的置物箱2 2 的壁面，也能容易去掉髒東西，由於地毯部22 1不會弄髒 ，所以方便性很好。 在本發明的實施方式中，如第1 6圖（a )所示，雖然 在凸部186設置有圓弧狀的卡合面186A，而凸部186的 形狀並不限於此，只要是能夠卡合於凹部1 8 4內的形狀即 可 ° 〔發明效果〕 本發明藉由上述的構造而可以發揮如下述的效果。 第1發明的機車的座墊開閉構造，以從側面來看朝前 下方且從上面來看其前部朝向車體內側接近的方式，來使 鉸鏈軸傾斜，在將座墊關閉的狀態，作成讓座墊底板前部 所設置的凸部與物品收容箱前部所設置的凹部卡合在一起 ，物品收容箱與座墊的卡合，是以凹部與凸部來進行的， 所以可以節省一個座墊扣，既能維持防盜機能又能減低成 本。 第2發明的機車座墊開閉構造，是讓鉸鏈軸通過卡合 部的下方附近，在將座墊關閉且使凹部與凸部卡合在一起 的狀態，即使使朝上的力量作用在座墊前部而想要以不合 理的方式將座墊打開，座墊也很難以鉸鏈軸爲中心旋轉， 座墊很難打開，可以更提高防盜效果。 -27- (24) (24)200401728 第3發明的機車的座墊開閉構造，是將凹部形成在物 品收容箱上部開口凸緣部，與特別來做出凹部的情況相比 ，可以更減少形成凹部的物品收容箱的形狀變更，可以減 少成本。 凸緣部是物品收容箱的上部緣部的提高剛性的部份’ - 所以藉由將凹部設置在該剛性較高的凸緣部，即使在有外 . 力經由座墊側的凸部作用在凹部時，也可以抑制凹部的變 形，能使座墊更難開啓。 Φ 【圖式簡單說明】 第1圖是本發明的機車的側面圖。 第2圖是顯示本發明的機車的後部的主要部分側面圖 〇 第3圖是本發明的機車的正面圖。 第4圖是本發明的機車的平面圖。 第5圖是顯示本發明的座墊鉸鏈的安裝狀態的立體圖 0 〇 第6圖是本發明的座墊鉸鏈的立體圖。 第7圖是顯示本發明的座墊鉸鏈的主要部分的立體圖 _ 〇 第8圖是顯示本發明的座墊鉸鏈的鉸鏈軸的傾斜情形 的說明圖。 第9圖是顯示本發明的座墊扣的安裝狀態的立體圖。 第1 〇圖是本發明的座墊扣的說明圖。 -28- (25) (25)200401728 第1 1圖是用來說明本發明的座墊鉸鏈的鉸鏈外殼的 剖面圖。 第1 2圖是顯示本發明的車體外殼的缺口部的說明圖 〇 第1 3圖是用來說明本發明的鉸鏈外殼的開啓動作的 作用圖。 第1 4圖是本發明的置物箱的立體圖。 第15圖是顯示本發明的雙人座墊的底面的底面圖。 第1 6圖是用來說明本發明的置物箱與雙人座墊的卡 合的剖面圖。 第1 7圖是用來說明本發明的置物箱內的分隔部的立 體圖。 第1 8圖是本發明的置物箱的剖面圖。 第1 9圖是本發明的置物箱的前部及中間部的平面圖 〇 第2 0圖是用來說明本發明的分隔板***部的剖面圖 〇 第2 1圖是顯示本發明的***到分隔板***部的分隔 板的剖面圖。 第22圖是本發明的地毯部的立體圖。 第2 3圖是顯示本發明的置物箱的使用例的作用圖。 第24圖是顯示本發明的置物箱的其他使用例的作用 圖。 第25圖是顯示傳統的座墊開閉構造的立體圖。 -29- (26) (26)200401728 〔圖號說明〕 1 〇 :機車 22 :物品收容箱（置物箱） 23 :座墊（雙人座墊） -
