200422223 玖、發明說明： 【發明所屬之技術領域】 本發明係關於一種腳踏車鞍座的安裝構造。 【先前技術】 第6、7圖係習知腳踏車鞍座之安裝構造例的分解斜視 圖。 在鞍座（5)的下面，具有倒T字型剖面的垂下執（6)係 以延伸於前後方向之形態設置。 另一方面，在鞍座柱（1)的上端固定有支持座（2)，而 該支持座（2)係具備從矩形底板（28)之兩側邊彎折直立之 側板部（21)(22)，同時在支持座（2)上收容有由左右疊合之 一對推壓塊（31) (32)所組成的夾具（3)。又，，該推壓塊 (31) (32)上，·形成有相互相對平行的推壓面（a) (b)，同時 在該推壓面（a)(b)的下部附近形成有延伸前後整個區域的 引導溝（33)(34)。並且，從垂下執（6)之下端兩側壁突出的 扣、洽凸·緣（61)(62)係可滑動自如地插入上述引導溝 (33)(34)。 在此結構中，以推壓塊（31)(32)的推壓面（a)(b)夾持 垂下軌（6)下部的平行側面（c)(d)部，並在該狀態下將推壓 塊（31)(32)收容於支持座（2)内。然後，將支持螺栓（71)及 角度調節螺栓（75)依序穿過分別形成於支持座（2)—邊側 板部（21)之前後端部的「轴承孔（23)及圓弧狀長孔（26)」— 「推壓塊（31)(32)的轴孔（30)(30)及螺栓穿通孔

又，欲調節鞍座（5)的俯角時，係以前側的支持螺栓（71) 為支點，使夾具（3)上下轉動後，再鎖緊角度調節螺栓（75) 及螺帽（7 6 h 【專利文獻】 日本特公平7— 40467號公報。 【發明内容】 (發明所欲解決之課題） 然而，上述之習知構造中，由夾具（3)所形成之垂下執 (6)的保持力，係僅藉由推壓塊（31)(32)的平行推壓面 (a)(b)從橫向夾壓上述垂下軌（6)下部的平行面（c)(d)來 確保，故有該部位之穩定性不足的問題。 本發明係有鑒於上述問題點而開發者，係於：『在具 備：突設於鞍座（5)下面而前後方向較長之垂下執（6);由 左右夾壓上述垂下執（6)的一對推壓塊（31)(32)所組成且 保持於鞍座柱（10)側的夾具（3);及令上述推壓塊（31) (32) 朝彼此接近之方向鎖緊的鎖緊具之腳踏車鞍座的安裝構造

扣合凸緣（61)(62)上方或下方區域的一對推壓塊（31)(32) 所組成，且保持於鞍座柱（1〇)側；及鎖緊具，將上述推壓 7 200422223 塊（31)(32)朝彼此接近之方向鎖緊， 其特徵在該腳踏車鞍座的安裝構造係具備： 上述垂下執（6)被上述推壓塊（31)(32)所夾壓部位，其 左右厚度係形成向下逐漸變厚的推拔狀， 藉由上述鎖緊具予以鎖緊時，上述推壓塊（31)(32)以 面接觸的狀態推壓上述垂下執（6)被夾壓部位的表面，同時 上述推壓塊（31)(32)的一部分係抵接於上述扣合凸緣 (61)(62)的上面。』 在此結構中，與申請專利範圍第1項同樣的，以推壓 塊（31)(32)從左右夾持垂下執（6)的向上加寬推拔部，且在 該狀態下，利用鎖緊具將推壓塊（31)(32)朝彼此接近之方 向鎖緊時，上述推拔部即可被推壓塊（31)(32)夾壓。 又，藉由向上加寬推拔部之鎖緊力的向上分力，使推 拔部之上方或下方的扣合凸緣（61) (62)得以被推壓塊 (31)(32)的一部分從下方推壓（推壓塊（31)(32)係從上方 抵接扣合凸緣（61 )(62))，藉以使垂下軌（6)得以被固定。 因此，根據上述技術手段，因為由垂下執（6)之推拔部 及扣合凸緣（61)(62)之上面兩部位係抵接推壓塊 (31)(32)，與上述習知構造所示僅藉由垂下執（6)之左右平 行面（c)(d)抵接推壓塊（31)(32)的情形相比較，本發明垂 下軌（6)的穩定性得以提昇。 申請專利範圍第3頊 申請專利範圍第3項的發明中，除了上述課題外，又 以提供一種即使上述鎖緊具的鎖緊力在腳踏車行走中降 8 200422223 低，鞍座（5)的俯角亦難以變化之腳踏車鞍座的安裝構造為 其課題。 亦即，上述習知構造中，當螺栓（41)(42)因腳踏車行 走時產生的震動而逐漸鬆弛時，設成預定俯角的夾具（3)會 因騎士的體重而轉動，因此，鞍座（5)的俯角無法維持適當 的角度。有鑒於此問題點，申請專利範圍第3項之發明中， 除了上述課題之外，又以提供一種「即使上述鎖緊具的鎖 緊力在腳踏車行走中降低，鞍座（5)的俯角亦難以變化之腳 踏車鞍座的安裝構造」為其課題。 申請專利’範圍第3項用以解決上述課題之技術手段， 係在申請專利範圍第2項中，『上述夾具（3)之結構係介裝 於裝設在上述鞍座柱（10)上部的左右側板部（2丨）（22)間， 上述鎖緊具係在令上述夹具（3)介裝於上述側板部 (21)(22)的狀態下，將該側板部（20(22)朝彼此接近之方 向鎖緊， 藉由上述鎖緊具的鎖緊而彼此接近而移動的上述側板 部（21)(22)，上述夾具（3)的上述推壓塊（31) (32)乃得以推 壓上述垂下執（6)。』 在此結構中，與習知構造相同地，將夾具（3)插入設於 鞍座柱（10)上部的左右侧板部（21)(22)之間，同時以構成 該夾具（3)之推壓塊（31)(32)從左右夾持垂下執（6)下面的 推拔部，且在該狀態下，利用鎖緊具將側板部（21) (22)朝 彼此接近的方向鎖緊時，上述推拔部即可被推壓塊（31) (32) 所夾壓，藉此方式，可將鞍座（5)固定在適當的姿勢。此外， 9 200422223 將介裝於鞍座柱（10)上部之側板部（21)(22)間的夹具（3) 俯角設定在適當狀態下，鎖緊鎖緊具時，即可進行鞍座（5) 的角度設定。 另一方面，坐在鞍座（5)上面的騎士體重可傳遞至推壓 塊（31)(32)對垂下執（6)的夾壓部分。在此狀態下，由於垂 下執（6)之上述夾壓部分係形成左右厚度往上增加的推拔 部，故該推拔部係呈楔狀壓入推壓塊（31) (32)之間。因此， 藉由上述推拔部可使上述推壓塊（31)(32)被推向彼此離開 的方向，且使鞍座柱（10)上部的側板部（21)(22)與推壓塊 (31)(32)的抵接力增大，這些因素可防止側板部（21)(22) 與夾具（3)與垂下執（6)之結合力降低。因此，即便鎖緊具 稍微鬆弛，鞍座（5)的俯角亦不易產生變化。 申請專利範圍第4頊 ^ 在申請專利範圍第3項中， 『上述鎖緊具係具備：支持螺栓（71)及螺合於該支持螺栓 的螺帽（72)，該支持螺栓（71)係可轉動自如地穿通上述夾 具（3)之前端附近下面所形成的左右方向轴孔（30)，且穿通 於分別開設在上述側板部（21) (22)的軸承孔（23)(24)間而 呈架設狀態；及 角度調節螺栓（75)及螺合該角度調節的螺帽（76)，該 角度調節螺栓（75)係穿通於以轴承孔（23)(24)為中心而形 成於上述側板部（21)(22)的圓弧狀長孔（26)(27)之間而呈 架設狀態，且貫穿上述夾具（3)之後端附近下面所形成的螺 栓穿通孔（39)， 10 200422223 並且夾置於上述側板部（21)(22)—邊外面及上述螺帽 (76)間的墊圈（78)所壓接之防滑用凹凸紋（29)，係形成於 上述的一邊外面。』 於此種結構中，在以支持螺栓（71)為中心令夾具（3) 上下轉動的角度設定狀態下，鎖緊角度調節螺栓（75)及螺 帽（76)時，該螺帽（76)内側的墊圈（78)會壓接於防滑用凹 凸紋（29)。因此，透過該防滑用凹凸紋（29)與墊圈（78)的 摩擦力，較不用擔心夾具（3)會再轉動。 史讀專利銥圍篦5瑁、篦fi頂 在申請4利範圍第1項至第4項中， 『對上述垂下軌（6)下邊呈垂直方向的多數微細直線溝係 形成於該垂下執（6)被夹壓的上述部位的表面， 並且，上述推壓塊（31)(32)的表面中，在推壓上述垂 下執（6)的面上，形成有可與上述直線溝嚙合的多數微細直 線溝。』在此結構中，藉由上述微細直線溝的嚙合，垂下 轨（6)及推壓塊（31)(32)不易滑動於前後方向。 另一方面，將申請專利範圍第5項及第6項的發明應 用於專利範圍第2項或第3項的發明時，將垂下軌（6) 狀壓入推壓塊⑻⑽之間的動作係沿著上述直 向’故不會妨害該推壓動作的順暢性。 (發明效果） 根據上述構成，本發明具有下列特殊效果。 下 申請專㈣圍第i項之發明中，垂下軌⑻的推拔部及 面兩雜係抵接於推壓塊（31)(32)及固定面。又，卜 200422223 專利範圍第2項之發明中，垂下執（6)的推拔部及扣合凸緣 (61)(62)的上面等兩個部位係抵接於推壓塊（31)(32)。因 此，此等發明中，與上述習知構造僅藉垂下執（6)之左右平 行面（c)(d)被推壓塊（31)(32)所壓接之情形相比較，垂下 執（6)的穩定性得以提昇。 申請專利範圍第3項之發明中，由於垂下執（6)下面的 推拔部係呈楔狀壓入推壓塊（31)(32)之間，故即使鎖緊具 稍微鬆弛，鞍座（5 )的俯角亦不易產生變化。因此，較不必 擔心設成預定俯角的鞍座（5)在腳踏車行走中不經意地變 回水平姿勢。 申請專利範圍第4項之發明中，螺帽（76)内側的墊圈 (78)係壓接於侧板表面的防滑用凹凸紋（2g)。因此，透過 該防滑用凹凸紋（29)及墊圈（78)的摩擦力，得以更確實地 防止鞍座（5)俯角的變化。 申請專利範圍第5項及第6項之發明中，藉由微細直 線溝的嚙合，垂下執（6)不易滑動於推壓塊（31)(32)的前後 方向。 【實施方式】 繼之，說明上述本發明之實施型態。 第1圖至第3圖所示之第i實施型態係對應上述申請 專利範圍第2項至第4項之發明。 ^如第1圖所示，在鞍座（5)下面，於前後方向突設有長 形垂下軌（6)，同時該垂下軌（6)的下部係藉由一對推壓塊 12 200422223 (31) (32)組成的夾具（3)從左右方向夾壓。並且，上述夾具 (3)係配置於鞍座柱（10)的上部，且可上下轉動自如地收容 於用以從左右方向夾壓上述夾具（3)的一對側板部（21)(22) 内，而該側板部（21)(22)係藉著支持螺栓（71)及角度調節 螺栓（75)朝彼此接近的方向鎖緊。 以下，更詳細地說明。 如第2、3圖所示，在合成樹脂製的鞍座（5)下面，向 下突出垂設有與鞍座一體成形的垂下執（6)，並且在該垂下 軌（6)的下端，朝左右方向突出有扣合凸緣（61)(62)。 連接於i下軌（6)之扣合凸緣（61)(62)上方的傾斜面 (63)係呈被後述推壓塊（31) (32)夾壓的狀態，同時該被夾. 壓部分的厚度係形成向上增厚的推拔狀。 夹壓上述垂下執（6)下部的夾具（3)係由具有左右（鞍 座（5)的橫寬方向）對稱形狀的一對推壓塊（31)(32)所構 成，同時該推壓塊（31)(32)之相對面係形成由上方至下方 彼此逐漸接近的候斜狀推壓面（37)(38)。並且，這些推壓 面（37)(38)的傾斜角度，係與由垂下執（6)下端突出之扣合 凸緣（61)(62)上方所連接之傾斜面（63)表面的傾斜角度一 致。藉此結構，推壓面（37) (38)與上述傾斜面（63)的表面 形成面接觸。此外，與前述習知構造同樣的，在推壓塊 (31)(32)下端的相對面形成有延伸於前後方向整個區域的 引導溝（33)(34)，從垂下執（6)的下端兩側壁突出的扣合凸 緣（61)(62)係可以滑動自如地插入該引導溝（33)(34)。 繼之，說明鎖緊支持座（2)的鎖緊具及收容該鎖緊具之 13 200422223 支持座（2)的構造。 本實施型態中，以上述鎖緊具來說，係採用鎖緊側板 部（21) (22)的支持螺栓（71)與角度調節螺栓（75)。 在上述侧板部（21)(22)的各前端下部分別開設有轴承 孔（23)(24)，且支持螺栓（71)係穿通該轴承孔（23)(24)而 呈架設狀態。並且，供支承螺栓（71)轉動自如地穿通用的 轴孔（30)(30)，係以在左右方向排成直線狀地貫穿設置在 推壓塊（31)(32)前端附近的下部，同時設有可螺合於該支 持螺栓（71)之前端螺絲部的螺帽（72)。 在側板部（21)(22)上，分別開設有以前端下部之轴承 孔（23)(24)為中心的圓弧狀長孔（26)(27)。另一方面，在 推壓塊（31)(32)後端附近的下部，螺栓穿通孔（39)(39)係 貫通於橫方向，且角度調節螺栓（75)係從支持座（2)側板部 (21)的圓弧長孔（26)，經由上述螺栓穿通孔（39) (39)穿過 另一邊側板部（22)的圓弧狀長孔（27)。然後，藉著墊圈（78) 將螺帽（76)螺合於該角度調節螺栓（75)的前端螺絲部。 又，在圓弧狀長孔（27)的周緣，跨涉上下方向的大致 全部區域，形成有防滑用凹凸紋（29)，使壓接於該防滑用 凹凸紋的墊圈（78)得以防止滑動。 再者，使用以構成支持座（2)之側板部（21)(22)下邊相 互銜接的底板（28)乃固定於鞍座柱（10)的上端。 接著，說明本實施型態之鞍座安裝構造的作用。 欲固定鞍座（5)時，用分離狀態下之推壓塊（31)(32) 的推壓面（37)(38)，由左右夾住垂下執（6)的下面推拔部 14 200422223 (連接於扣合凸緣（61 )(62)上方的傾斜面（63))，並令該狀 態下的推壓塊（31)(32)插入支持座（2)的側板部（21)(22) 間。 繼之，令支持螺栓（71)從形成於支持座（2)—邊側板部 (21)的轴承孔（23)，經由推壓塊（31)(32)前端下部的軸孔 (30) (30)，穿過形成於支持座（2)另一邊側板部（22)的軸承 孔（24)，並將螺帽（72)隔著墊圈（79)緩緩地螺合於該支持 螺栓的前端。 然後，將角度調節螺栓（7 5 )從形成於支持座（2 ) —邊側 板部（21)的圓草狀長孔（26)，經由推壓塊（31)(32)後端下 部的螺栓穿通孔（39)(39)，穿過形成於支持座（2)另一邊側 板部（22)的圓弧狀轴承孔（27)，並將螺帽（76)藉著墊圈（78) 緩緩地螺合於該角度調節螺栓的前端。藉此方式，鞍座（5) 得以暫時安裝於鞍座柱（10)的上端。 其次，以支持螺栓（71)部分作為轉動支點，使夾具（3) 的後端上下移動後鎖緊螺帽（76)(72)。於是，支持座（2)的 側板部（21)(22)隨著鎖緊動作而向内側彎曲地變形移動， 因此，推壓塊（31)(32)會推壓垂下執（6)側，且上述推壓塊 (31) (32)的推壓面（37) (36)會推壓垂下執（6)的推拔狀下 部側面（連接於扣合凸緣（61)(62)上方的傾斜面（63))。藉 此方式，垂下軌（6)乃得以利用夾具（3)固定，且如第2圖 假想線誇大顯示者，鞍座（5)被設定在預定的俯角。 又，如第3圖所示，在該狀態下，推壓塊（31)(32)之 引導溝（33) (34)的上壁（330) (340)係抵接於垂下軌（6)下 15 200422223 面之扣合凸緣（61 )(62)的上面（69)(69)。換言之，透過推 壓塊（31)(32)對向上加寬推拔部（傾斜面（63)(63))之鎖緊 力的向上分力，即得以令扣合凸緣（61)(62)的上面（69)(69) 由下方推向推壓塊（31)(32)引導溝（33)(34)的上壁 (330)(340)。 因此，本實施型態中，由於屬於垂下軌（6)推拔部之傾 斜面（63)(63)及扣合凸緣（61)(62)的上面等兩個部位抵接 於推壓塊（31)(32)，與習知例所示僅利用垂下軌（6)左右平 行面（c)(d)被推壓塊（31)(32)壓接的情形相比較，垂下執 (6)的穩定性得以提昇。 此外，鎖緊支持螺栓（71)及角度調節螺栓（75)前，先 令垂下軌（6)在推壓塊（31)(32)之間往前後滑動，即可設定 鞍座（5)的前後位置。 接著，於鞍座（5)固定在適當姿勢的狀態下，當腳踏車 騎士坐在該鞍座（5)時，該騎士的體重會作用在夾具（3)所 夾持之垂下軌（6)的夾壓部。於是，該被夾壓的部位（連接 於扣合凸緣（61) (62)上方的傾斜面（63))會呈楔狀緊密地 壓入推壓塊（31)(32)的推壓面（37)(38)間，因此，推壓塊 (31)(32)亦會大力地壓接在支持座（2)的兩側板部 (21)(22)。藉此結構，即使支持螺栓（71)及角度調節螺栓 (75)有些鬆弛，推壓塊（31)(32)對於上述支持座（2)之兩側 板部（21)(22)的壓接力也不會變小，較可不必擔心設成預 定俯角的鞍座（5)在腳踏車行走中會不經意地變回水平姿 勢。 16 200422223 在上述實施型態中，連接於扣合凸緣（61)(62)上方的 部分係形成傾斜面（63)(63)，而如第3圖之假想線所示， 亦可構成在傾斜面（63)(63)的上方突設上述扣合凸緣 (61)(62)，並且亦可在推壓塊（31)(32)上，於上述扣合凸 緣（61) (62)的相對位置形成引導溝（33)(34)。亦即，利用 推壓塊（31)(32)從左右方向夹壓假想線所示之扣合凸緣 (61)(62)的下方區域（推拔部），同時令扣合凸緣（61) (62) 抵接於假想線所示之引導溝（33)(34)上壁。 第2實施型態 上述實施型態中，雖然垂下軌（6)下部之推拔部的表面 以及將其夾壓之推壓塊（31)(32)的推壓面（37)(38)皆為平 滑面，但是也可在此等構件上形成延伸於上下方向之微細 的多數直線溝。（如專利申請範圍第5項及第6項之發明）。 易言之，如第4圖之第2實施型態所示，在垂下軌（6) 的下邊（600)部位上，將垂直方向之多數微細直線溝 (601 )(601 )形成於該垂下執（6)的推拔部下部表面。另一方 *' ** / 面，也可在推壓塊（31)(32)及屬於上述直線溝（601)(601) 對應部位的推壓面（37)(38)上，形成與上述直線溝 (601 )(601 )嚙合的微細直線溝（371 )(381)。 藉此結構，透過形成於推壓塊（31)(32)及垂下軌（6) 之直線溝（371)(381)(601)(601)的嚙合，垂下執（6)難以在 推壓塊（31)(32)滑動於前後方向。另一方面，垂下軌（6)呈 楔狀壓入推壓塊（31)(32)之間的動作係沿著上述直線溝 (371)(381)(601)(601 )的方向，故不會妨礙該壓入動作的 17 200422223 順暢性。 第3實施剞態‘ 繼之，參考第5圖說明對應於上述申請專利範圍第1 項的第3實施型態。 如第5圖所示，由鞍座（5)下面突出的垂下軌（6)，其 被推壓塊（31)(32)所央壓之部位之左右方向厚度係形成向 下逐漸地增大。再者，在垂下軌（6)的下端，設有左右突出 的扣合凸緣（61)(62)。 另一方面，與上述第1、第2實施型態同樣的，扣合 凸緣（61)(62)係可滑動自如地插入於用以構成夾具（3)之 推壓塊（31) (32)相對面所形成的引導溝（33)(34)，且垂下 執（6)的下面（69)係抵接於引導溝（33)(34)的底壁 (331)(341)。因此，本實施型態中，上述底壁（331)(341) 係對應於前述專利申請範圍第1項之發明所界定的固定面。 又，在用以構成夾具（3)之推壓塊（31) (32)前後端的下 部，與前述各實施型態同樣的轴孔（30)(30)或螺栓穿通孔 (39)(39)係以貫通左右方向之態樣形成。 此外，設置於鞍座柱（10)上部的支持座（2)則形成與第 1圖相同的構造。 在此結構中，與上述第1實施型態同樣的，在垂下軌 (6)被推壓塊（31)(32)從左右方向夾住的狀態下，將這些推 壓塊（31) (32)裝設在支持座（2)内，然後，將穿通支持座（2) 的側板部（21) (22)及夾具（3)之支持螺栓（71)與角度調節 螺栓（75)的前端，螺合（72)(76)螺帽並加以鎖緊。 18 200422223 於是，透過形成向下加寬狀態之上述推拔部（傾斜面 (63)(63))之鎖緊力的向下分力，即得以令垂下執（6)的下 面（69)推壓於屬於固定面之引導溝（33)(34)的底壁 (331)(341 )，藉以固定垂下執（6)。 因此，本實施型態中，由於垂下軌（6)的推拔部及下面 兩部位皆抵接於推壓塊（31)(32)，故與上述習知構造所示 僅垂下軌（6)的左右平行面（c)(d)被推壓塊（31) (32)壓接 的情形相比較，垂下軌（6 )的穩定性得以提昇。

"In this structure, the same as above The conventional structure is the same, and the pressing blocks (31) (32) for forming the clamps (3) on the side of the saddle post (10) are widened downward by clamping the hanging rail (6) in the left and right directions. Pushing part, and in this state, the pressing block (31) (32) is locked in a direction approaching each other by a locking tool. In this way, the above pushing part is saved; the pressing block (31) (32) ). The downward component of the locking force of the pushing part is widened downward, so that the lower part of the down rail (6) is pushed opposite to it. Fixed surface, by which the fixed down rail (6) is fixed. _; _ 2 of the patent application scope of the patent application to solve the above-mentioned problem, the scope of the patent application of the second technical means is as follows. "Protruding from the left and right sides of the buckle convex The hanging rail (6) with the edge (61) (62) and long in the front-rear direction is protruded below the saddle (5), and has: a clamp (3), which presses the buckle on the left and right sides from left to right It is composed of a pair of pressing blocks (31) (32) above or below the flange (61) (62), and is held on the side of the saddle post (10); and a locking device, which presses the above 7 200422223 The blocks (31) and (32) are locked in the direction of approaching each other, and are characterized in that the mounting structure of the saddle of the bicycle is provided with: the above-mentioned hanging handle (6) is sandwiched by the above-mentioned pressing block (31) (32) The left and right thicknesses are formed in a push-down shape that gradually becomes thicker. When locked by the locking device, the pressing blocks (31) (32) push the hanging handle (6) in a state of surface contact. At the same time, a part of the surface of the pinched portion is abutted against the upper surface of the fastening flange (61) (62). 』In this structure, similar to the first item in the scope of the patent application, the push-up block (31) (32) widens the push-up part that is suspended from the left and right grips (6), and in this state, uses When the locking block locks the pressing blocks (31) and (32) in a direction approaching each other, the above-mentioned pushing-out portion can be pinched by the pressing blocks (31) (32). In addition, by widening the upward component of the locking force of the pushing part upward, the fastening flange (61) (62) above or below the pushing part can be pushed by the block (31) (32). A part is pushed from below (the pushing blocks (31) (32) abut against the engaging flanges (61) (62) from above)), so that the down rail (6) can be fixed. Therefore, according to the above technical means, since the upper part of the pushing part of the hanging handle (6) and the upper part of the fastening flange (61) (62) are in contact with the pressing block (31) (32), it is in accordance with the above-mentioned conventional knowledge. The structure shows that the stability of the hanging rail (6) of the present invention is improved only by comparing the case where the left and right parallel surfaces (c) (d) of the hanging handle (6) abut the pressing block (31) (32). In addition to the above-mentioned subject, the invention in item 3 in the scope of patent application, and the invention in item 3 in the scope of patent application, provides a method for reducing the depression force of the saddle (5) even if the locking force of the above-mentioned locking device is reduced during cycling. The mounting structure of a bicycle saddle that is also difficult to change is its subject. That is, in the above-mentioned conventional structure, when the bolts (41) (42) gradually loosen due to the vibration generated when the bicycle is running, the jig (3) set to a predetermined depression angle will rotate due to the weight of the rider, so the saddle (5) The depression angle cannot be maintained at an appropriate angle. In view of this problem, in addition to the above-mentioned subject, in the invention in the third scope of the patent application, in addition to the above-mentioned problem, it is provided that "even if the locking force of the above-mentioned locking device is reduced while the bicycle is running, the depression angle of the saddle (5) is also "The mounting structure of a bicycle saddle that is difficult to change" is its subject. The third item of the scope of the patent application is the technical means to solve the above-mentioned problems. In the second item of the scope of the patent application, "the structure of the above-mentioned clamp (3) is installed in the upper part of the saddle post (10). Between the left and right side plate portions (2 丨) (22), the locking device is in a state where the clamp (3) is interposed in the side plate portion (21) (22), and the side plate portion (20 (22) is directed toward The side plates (21) and (22) that are locked in a direction close to each other and moved close to each other by the locking of the locking device, and the pressing blocks (31) and (32) of the fixture (3) are obtained. Push the hanging handle (6). ”In this structure, the clamp (3) is inserted between the left and right side plate portions (21) (22) provided on the upper part of the saddle post (10), as in the conventional structure. At the same time, the pushing part under the (6) is held down from the left and right by the pressing blocks (31) (32) constituting the clamp (3), and in this state, the side plate part (21) is locked by the locking device.

When the lock is locked, the saddle (5 On the other hand, the weight of the knight sitting on the saddle (5) can be transmitted to the clamping part of the pressing block (31) (32) to the hanging handle (6). In this state, due to hanging The above-mentioned pinching part of (6) forms a pushing part with the left and right thickness increasing upwards, so the pushing part is wedge-shaped into the pushing block (31) (32). Therefore, by the pushing The pulling part can push the pressing blocks (31) (32) in a direction away from each other, and make the side plate parts (21) (22) and the pressing blocks (31) (32) of the upper part of the saddle post (10). These factors can increase the contact force of the side plate (21) (22), the clamp (3), and the hanging handle (6). Therefore, even if the locking device is slightly loose, the depression angle of the saddle (5) It is also difficult to produce changes. In the scope of patent application No. 4 顼 ^ In the scope of patent application No. 3, "The above-mentioned locking device is provided with a support bolt (71) and a nut (72) screwed to the support bolt, The supporting bolt (71) is rotatably penetrated through the left and right direction shaft holes (30) formed near the front end of the clamp (3) and below, and through the bearing holes respectively opened in the side plate portions (21) (22). (23) and (24) in an erected state; and an angle adjustment bolt (75) and a nut (76) screwed into the angle adjustment, the angle adjustment bolt (75) is passed through the bearing hole (23) (24) ) As a center and is formed between the arc-shaped long holes (26) (27) of the side plate portions (21) (22) and is in a erected state, and penetrates through the bolts formed near the rear end of the clamp (3) below Holes (39), 10 200422223, and non-slip reliefs (29) crimped by the washer (78) sandwiched between the side plate portion (21) (22) —the outside of the side and the nut (76), are formed On the side above. 』In this kind of structure, the nut (76) is tightened when the angle adjustment bolt (75) and the nut (76) are locked under the angle setting state in which the clamp (3) is rotated up and down with the support bolt (71) as the center. ) The washer (78) on the inside is crimped to the anti-slip relief (29). Therefore, through the frictional force of the anti-slip relief (29) and the washer (78), there is no need to worry that the clamp (3) will rotate again. In the history reading patent Iridium 篦 5 瑁, 篦 fi 顶 in the application of the scope of benefits 1 to 4 of the application, "Most of the fine straight grooves that are perpendicular to the lower rail (6) above are formed in the vertical suspension ( 6) The surface of the part being pinched, and among the surfaces of the pressing blocks (31) and (32), a plurality of surfaces that can be engaged with the linear grooves are formed on the surface that presses the hanging down (6). Fine straight grooves. "In this structure, the above-mentioned fine linear grooves make it difficult for the down rail (6) and the pressing block (31) (32) to slide in the front-rear direction. On the other hand, when applying the inventions in the scope of patent application Nos. 5 and 6 to the inventions in scope 2 or 3 of the patent scope, press the downward rail (6) into the action system between the pressing blocks ⑻⑽ In the straight direction, the smoothness of the pushing action is not hindered. (Effects of the Invention) According to the above configuration, the present invention has the following special effects. In the invention of item i of the following application, the pushing part and the surface of the hanging rail are in contact with the pressing block (31) (32) and the fixed surface. Moreover, in the invention of the second item of the patent range of 200422223, two parts, such as the pushing part of the hanging handle (6) and the upper surface of the fastening flange (61) (62), are in contact with the pressing block (31) ( 32). Therefore, in these inventions, compared with the case where the above-mentioned conventional structure is only crimped by the right and left parallel planes (c) (d) of the down-holding (6) by the pressing block (31) (32), the down-holding ( 6) Stability is improved. In the invention in the third scope of the patent application, since the pushing part under the hanging handle (6) is wedged into the pressing block (31) (32), even if the locking device is slightly loose, the saddle ( 5) The depression angle is not easy to change. Therefore, it is less necessary to worry about the saddle (5) set to a predetermined depression angle inadvertently changing back to the horizontal posture while walking on the bicycle. In the invention according to the fourth item of the patent application, the washer (78) on the inner side of the nut (76) is a non-slip uneven pattern (2g) crimped to the surface of the side plate. Therefore, it is possible to more reliably prevent the depression angle of the saddle (5) by the frictional force of the non-slip relief (29) and the washer (78). In the inventions of claims 5 and 6, the pendant grip (6) is difficult to slide in the front-rear direction of the pressing block (31) (32) by the meshing of the fine linear grooves. [Embodiment] Next, an embodiment of the present invention will be described. The i-th embodiment shown in Figs. 1 to 3 corresponds to the inventions in the second to fourth scope of the patent application. ^ As shown in Fig. 1, under the saddle (5), a long and long down rail (6) is protruded in the front-rear direction, and the lower part of the down rail (6) is supported by a pair of pushing blocks 12 200422223 ( 31) The clamp (3) composed of (32) is clamped from the left and right directions. In addition, the jig (3) is arranged on the upper part of the saddle post (10) and is rotatably accommodated in a pair of side plate portions (21) (22) for clamping the jig (3) from left and right directions. Inside, and the side plate portion (21) (22) is locked in a direction approaching each other by a support bolt (71) and an angle adjustment bolt (75). Hereinafter, it will be described in more detail. As shown in Figs. 2 and 3, under the saddle (5) made of synthetic resin, a hanging handle (6) integrally formed with the saddle is protruded downward, and the lower end of the hanging rail (6) is protruded downward, Snap flanges (61) (62) protrude in the left-right direction. The inclined surface (63) above the fastening flange (61) (62) connected to the lower rail (6) is in a state of being pinched by the pressing block (31) (32) described later, and it should be pinched at the same time. The thickness of the part is formed in a push-up shape which is thickened upward. The clamp (3) for clamping the lower part of the hanging handle (6) is composed of a pair of pressing blocks (31) (32) having a symmetrical shape of left and right (the width and width direction of the saddle (5)). The opposing surfaces of the blocks (31) and (32) form oblique pressing surfaces (37) and (38) that are gradually approaching each other from top to bottom. In addition, the inclination angle of these pressing surfaces (37) (38) is the inclination angle with the surface of the inclined surface (63) connected above the fastening flange (61) (62) protruding from the lower end of the hanging handle (6). Consistent. With this structure, the pressing surfaces (37) (38) are brought into surface contact with the surface of the inclined surface (63). In addition, similar to the conventional structure described above, a guide groove (33) (34) is formed on the opposite surface of the lower end of the pressing block (31) (32) to extend over the entire area in the front-rear direction. The fastening flanges (61) (62) protruding from the two side walls can be slidably inserted into the guide grooves (33) (34). Next, a description will be given of the lock fixture of the lock support base (2) and the structure of the 13 200422223 support base (2) accommodating the lock fixture. In this embodiment, the above-mentioned locking device is a supporting bolt (71) and an angle adjusting bolt (75) for locking the side plate portion (21) (22). Bearing holes (23) and (24) are respectively formed at the lower ends of the front ends of the side plate portions (21) and (22), and support bolts (71) pass through the bearing holes (23) (24) and are erected. In addition, the support bolt (71) is rotatably passed through the universal shaft hole (30) (30), and is arranged in a straight line in the left and right direction through a lower portion provided near the front end of the pressing block (31) (32). At the same time, a nut (72) that can be screwed to the front screw portion of the support bolt (71) is provided. The side plate portions (21) and (22) are respectively provided with arc-shaped long holes (26) (27) centered on the bearing holes (23) (24) at the lower end of the front end. On the other hand, in the lower part near the rear end of the pressing block (31) (32), the bolt penetration holes (39) (39) are penetrated in the horizontal direction, and the angle adjustment bolt (75) is from the side plate of the support seat (2) The arc-shaped long hole (26) of the portion (21) passes through the arc-shaped long hole (27) of the other side plate portion (22) through the bolt through hole (39) (39). Then, the nut (76) is screwed to the front screw portion of the angle adjustment bolt (75) by a washer (78). In addition, a non-slip groove (29) is formed on the periphery of the arc-shaped long hole (27) across almost the entire area in the up-down direction, and the washer (78) crimped to the non-slip groove is prevented from sliding. . In addition, a bottom plate (28) used to interconnect the lower sides of the side plate portions (21) (22) of the support base (2) is fixed to the upper end of the saddle post (10). Next, the function of the saddle mounting structure of this embodiment will be described. To fix the saddle (5), use the pressing surface (37) (38) of the pressing block (31) (32) in the separated state, and clamp the lower pushing part 14 of the hanging handle (6) from left to right. (Connected to the inclined surface (63) above the fastening flange (61) (62)), and insert the pressing block (31) (32) in this state into the side plate portion (21) of the support base (2) ( 22). Next, the support bolt (71) is made from the bearing hole (23) formed in the support seat (2)-the side plate portion (21), through the shaft hole (30) at the front end of the pressing block (31) (32) ( 30), through the bearing hole (24) formed in the side plate portion (22) on the other side of the support base (2), and screwing the nut (72) to the front end of the support bolt through the washer (79) slowly . Then, the angle adjusting bolt (7 5) is passed from the round grass-like long hole (26) formed in the support seat (2) to the side plate portion (21), and passes through the bolt at the lower end of the rear end of the pressing block (31) (32). Pass through holes (39) (39), pass through the arc-shaped bearing holes (27) formed in the side plate portion (22) on the other side of the support base (2), and slowly pass the nut (76) through the washer (78) The ground is screwed to the front end of the angle adjustment bolt. In this way, the saddle (5) can be temporarily installed on the upper end of the saddle post (10). Secondly, the support bolt (71) is used as a rotation fulcrum, and the rear end of the clamp (3) is moved up and down, and then the nut (76) (72) is locked. Then, the side plate portion (21) (22) of the support base (2) is deformed and moved inwardly as the locking action is performed. Therefore, the pressing block (31) (32) pushes the side of the pendant (6), And the pressing surface (37) (36) of the above-mentioned pressing block (31) (32) will push the push-down lower side of the hanging handle (6) (connected to the top of the fastening flange (61) (62)) Inclined surface (63)). In this way, the hanging rail (6) can be fixed by the fixture (3), and as shown in Fig. 2 the imaginary line exaggerates the display, and the saddle (5) is set at a predetermined depression angle. In addition, as shown in FIG. 3, in this state, the upper walls (330) (340) of the guide grooves (33) (34) of the pressing blocks (31) (32) are in contact with the down rails (6). Bottom 15 200422223 The top (69) (69) of the fastening flange (61) (62). In other words, through the upward component of the locking force of the pushing block (31) (32) to widen the pushing-up portion (inclined surface (63) (63)) upward, the buckle flange (61) (62) The top (69) (69) of) is pushed from below to the upper walls (330) (340) of the guide block (31) (32) guide groove (33) (34). Therefore, in this embodiment, two parts, such as the inclined surface (63) (63) and the upper surface of the fastening flange (61) (62), which belong to the push-down portion of the down rail (6), abut the pressing block. (31) (32), compared with the case where only the left and right parallel planes (c) and (d) of the vertical rail (6) and (d) are pressed by the pressing block (31) and (32) as shown in the conventional example, ) Stability has been improved. In addition, before locking the support bolt (71) and the angle adjustment bolt (75), first let the down rail (6) slide back and forth between the pressing blocks (31) (32) to set the saddle (5). Fore and aft positions. Next, in the state where the saddle (5) is fixed in an appropriate posture, when the rider rides on the saddle (5), the weight of the rider will act on the hanging rail (6) held by the clamp (3). Clamping section. Then, the pinched part (the inclined surface (63) connected above the fastening flange (61) (62)) will be pressed into the pressing surface of the pressing block (31) (32) tightly in a wedge shape. (37) to (38), therefore, the pressing block (31) (32) will also be strongly pressed against the two plate portions (21) (22) on both sides of the support base (2). With this structure, even if the support bolt (71) and the angle adjustment bolt (75) are loosened, the pressing force of the pressing block (31) (32) on the two side plate portions (21) (22) of the support seat (2) is also It does not become smaller, and it is less necessary to worry that the saddle (5) set to a predetermined depression angle may inadvertently return to a horizontal posture when walking on a bicycle. 16 200422223 In the above embodiment, the part connected above the fastening flange (61) (62) forms an inclined surface (63) (63), and as shown by the imaginary line in FIG. 3, it can also be formed in The above-mentioned fastening flange (61) (62) is protruded above the inclined surface (63) (63), and can also be on the pressing block (31) (32) to the above-mentioned fastening flange (61) (62) The relative positions of) form guide grooves (33) and (34). That is, the lower area (pushing portion) of the fastening flange (61) (62) shown by the imaginary line is sandwiched from the left and right directions by the pressing blocks (31) (32), and the fastening flange (61) ) (62) abut the upper wall of the guide groove (33) (34) shown by the imaginary line. Second Embodiment According to the above embodiment, although the surface of the pushing portion at the lower part of the down rail (6) and the pressing surfaces (37) (38) of the pressing block (31) (32) that sandwiched it are both It is a smooth surface, but a plurality of fine straight grooves extending in the vertical direction may be formed on these members. (Such as inventions in the scope of patent application items 5 and 6). In other words, as shown in the second embodiment of FIG. 4, a plurality of fine straight grooves (601) (601) in the vertical direction are formed on the lower side (600) of the vertical rail (6) in the vertical rail.

Therefore, in this embodiment, the bottom wall (331) (341) corresponds to the fixed surface defined by the invention in the first scope of the aforementioned patent application. In addition, in the lower portions of the front and rear ends of the pressing blocks (31) (32) for constituting the jig (3), the same shaft holes (30) (30) or bolt penetration holes (39) (39) as in the previous embodiments are used. It is formed so as to penetrate left and right. In addition, the support seat (2) provided on the upper part of the saddle post (10) has the same structure as that of the first figure. In this structure, as in the first embodiment, the pressing rails (31) (32) are sandwiched by the pressing blocks (31) (32) from the left and right directions, and the pressing blocks (31) (32) ) Is installed in the support base (2), and then the front end of the support bolt (71) and the angle adjustment bolt (75) passing through the side plate portion (21) (22) of the support base (2) and the clamp (3), Screw in (72) (76) nuts and lock them. 18 200422223 Then, by the downward component of the locking force of the above-mentioned pushing part (inclined surface (63) (63)) forming the downward widened state, the lower part (69) of the hanging handle (6) can be pushed It is pressed against the bottom walls (331) (341) of the guide grooves (33) (34) belonging to the fixed surface, so as to fix the hanging (6). Therefore, in this embodiment type, since the push-out part and the lower two parts of the hanging rail (6) are in contact with the pressing block (31) (32), only the hanging rail (6) is shown as the conventional structure. Compared with the case where the left and right parallel planes (c) and (d) are crimped by the pressing blocks (31) (32), the stability of the down rail (6) is improved. In addition, the periphery of the circle to the solitary long hole (26), which is formed on one side plate portion (21) of the support base (2), can also be used to form a non-slip concave and convex pattern, and the angle adjustment bolt (75) The head abuts against this uneven surface for slip prevention. 19 200422223 [Brief description of the drawings] Fig. 1 is an exploded perspective view illustrating a mounting structure of a saddle of a bicycle according to an embodiment of the present invention.
