Figure 2 shows the state in which the suspension function is blocked (locked state). Fig. 3 is a diagram showing the relationship between the fixed member and the movable member in an unlocked state. Fig. 4 is a diagram showing the relationship between the fixed member and the movable member in the locked state. Fig. 5 is an embodiment in which the positional relationship between the fixed member and the movable member cannot be maintained in the state of being movable in the up-and-down direction and the state in which the upper and lower directions are inoperable. Fig. 6 shows the intermediate position in the movable state in the up and down direction and the inoperable state in the up and down direction. Fig. 7 is an example of an indexing mechanism which cannot maintain the positional relationship between the fixed member and the movable member in the middle. According to the first embodiment of the present invention, the suspension forks are inserted into the forks 3a and 3b of the crown 2, inserted into the bottom casing 1 through the sleeve 15, and fixed by bolts 13 and fixed. The nut 14 is assembled so as to be movable in the up and down direction by a certain amount, and then the fork rod 16 which is pressed into the crown is assembled to the head pipe. The main spring 17 for suspension and the damper 18 are assembled into the fork 3a'. The strength of the main spring 17 can be adjusted by the adjustment knob 19. The fixing member 4, the movable member 5, the auxiliary member 6, and the auxiliary spring 8 are assembled into the fork pipe 3b. The auxiliary spring retainer 7 provided with a 6-hole hole at the lower portion is fixed to the substantially bow-shaped fixing member 4 by the screw 9, and the 6-hole hole of the auxiliary spring retainer 7 is inserted into the 6-head of the fixing bolt 1 3 At the time of the portion 1 3 a, the fixing member can be set to be non-rotatable above the fixing bolt.
1309214 在固定構件上方部上,設置有可對固定構件4上下方向 可作動而不可轉動之補助構件6,藉由設置於固定構件外周 部上的補助彈簧8,而經常地向上方施加彈迫力。而,將補 助構件之內徑部做成與固定構件同樣的大略成蝴蝶結狀之 時’可做成對固定構件不可轉動。 在補助構件6的上部端面上形成有山形的凹凸部6a,其 被構成可啣合到可動構件下部的山形的凹凸部5a中。 在下部端面上與補助構件6的山形的凹凸部6 a啣合的 山形的凹凸部5a,在上部端面形成有橢圓孔5b,內徑部設 置有與固定構件同樣的大略成蝴蝶結狀之空洞部5 c之可動 構件5,係被設置於補助構件6的上方,利用由補助彈簧8 賦予補助構件6的彈迫力,而經常地向上方彈壓,而經常地 抵接於螺鎖到叉管3 b中的頂蓋1 1上。在該狀態中,固定構 件4上部端面4 a與可動構件5下部端面5 d設置有若干之間 隙P。 在頂蓋Π上設置有前端部1 0 a做成橢圓形的鎖住功能 之切換鈕10,該橢圓形的前端部10a被插入可動構件5的橢 圓孔5 b中,因此將切換鈕轉動之時,可轉動可動構件。 在通常狀態、即懸吊功能啓動的狀態下,乘上自行車之 情形’係在第1圖所示的非鎖住狀態下使用。在該狀態中, 固定構件4與可動構件5如第3圖所示的位置關係,即固定 構件變成可插入可動構件之空洞部5 c中的位置關係,因此 懸吊前叉在上下方向上變成可作動的狀態。 在該狀態中,由於路面的凹凸而產生來自下方的衝擊之 1309214 時’底殻1抵抗主彈簧1 7而朝向上方運動。此時,補助彈 簧8不僅將補助構件及可動構件向上方彈迫,而且亦有做爲 懸吊之補助彈簧的功能。1309214 An auxiliary member 6 which is movable in the vertical direction of the fixing member 4 and is rotatable is provided on the upper portion of the fixing member, and the assisting spring 8 provided on the outer peripheral portion of the fixing member is constantly applied with an elastic force upward. On the other hand, when the inner diameter portion of the auxiliary member is formed into a substantially bow-like shape similar to the fixing member, the fixing member can be made non-rotatable. A mountain-shaped uneven portion 6a is formed on the upper end surface of the auxiliary member 6, and is formed in a mountain-shaped uneven portion 5a that can be engaged with the lower portion of the movable member. The mountain-shaped uneven portion 5a that is engaged with the mountain-shaped uneven portion 6a of the auxiliary member 6 on the lower end surface has an elliptical hole 5b formed in the upper end surface, and the inner diameter portion is provided with a substantially bow-like hollow portion similar to the fixing member. The movable member 5 of 5 c is provided above the auxiliary member 6, and is constantly biased upward by the elastic force applied to the auxiliary member 6 by the auxiliary spring 8, and is often abutted against the screw to the fork 3b. In the top cover 1 1 . In this state, the upper end surface 4a of the fixed member 4 and the lower end surface 5d of the movable member 5 are provided with a plurality of gaps P. The top cover 10 is provided with a front end portion 10 a which is formed into an elliptical locking function switch button 10, and the elliptical front end portion 10a is inserted into the elliptical hole 5 b of the movable member 5, thereby rotating the switching button The movable member can be rotated. In the normal state, that is, the state in which the suspension function is activated, the case of riding the bicycle is used in the non-locked state shown in Fig. 1. In this state, the positional relationship between the fixing member 4 and the movable member 5 as shown in Fig. 3, that is, the fixing member becomes a positional relationship in the hollow portion 5c into which the movable member can be inserted, so that the suspended front fork becomes in the up and down direction. Actuable state. In this state, when the impact from the lower side is generated 1309214 due to the unevenness of the road surface, the bottom case 1 moves upward against the main spring 17 . At this time, the auxiliary spring 8 not only ejects the auxiliary member and the movable member upward, but also functions as a supplementary spring for suspension.
切換鈕之橢圓形的前端部10a被插入可動構件的橢圓孔 5 b中,固定構件上部端面4 a與可動構件下部端面5 d設置有 若干之間隙p ’因此將切換鈕1 0轉動90度之時,並無大的 抵抗而亦將可動構件5轉動9 0度,而成爲第4圖所示的狀 態。在該狀態中,爲了阻止可動構件5對固定構件4之插入, 朝向底殼之上方的運動亦被阻止,因此亦不啓動懸吊功能。 即變成鎖住狀態。 在此之可動構件5及補助構件6上,設置有每90度互 相啣合的山形之凹凸部5 a,6a,因此切換鈕10及可動構件5 必須每9 0度做轉動。例如,將切換鈕1 〇做4 5度轉動之情 形’可動構件5亦做45度轉動,因而如第6圖,變成可動 構件與補助構件在山形斜面之途中抵接之狀態。在此時點將 手離開之時,補助構件藉由補助彈簧8而永遠向上方彈迫, 因此雖然一方面使斜面向山形啣合的X方向轉動、一面滑 入’但是被保持於不可轉動的固定構件4上所保持的補助構 件無法轉動,因此一方面向上方移動、一方面使可動構件向 Y方向轉動,因而返回如第5圖所示可動構件與補助構件啣 合的位置上。 即,即使做成在非9 0度的途中之位置上保持切換鈕及 可動構件之時,亦自動地變成被修正到每9 0度之啣合位置 上,因此可動構件與固定構件一定被保持於第3圖或第4圖 1309214 所示之位置關係上。 即’可動構件可插入固定構件上的位置,僅能被保持於 抵接面之面積爲最大的位置(第4圖斜線部),此係在懸吊功 能之鎖住時’對來自路面的衝擊可保證被保持於最大強度的 位置。 並且,即使未設置特別的分度機構之時,該構造本身亦 具有分度的角色,因此並不需要另外的零件,及組合的麻煩。The elliptical front end portion 10a of the switching button is inserted into the elliptical hole 5b of the movable member, and the fixed member upper end surface 4a and the movable member lower end surface 5d are provided with a plurality of gaps p' so that the switching knob 10 is rotated by 90 degrees. At this time, the movable member 5 is also rotated by 90 degrees without great resistance, and becomes the state shown in Fig. 4. In this state, in order to prevent the insertion of the movable member 5 against the fixed member 4, the movement toward the upper side of the bottom case is also prevented, so that the suspension function is not activated. It becomes a locked state. Here, the movable member 5 and the auxiliary member 6 are provided with the mountain-shaped uneven portions 5a, 6a which are engaged with each other at 90 degrees. Therefore, the switching knob 10 and the movable member 5 must be rotated every 90 degrees. For example, the switching member 1 is rotated at 45 degrees, and the movable member 5 is also rotated by 45 degrees. Therefore, as shown in Fig. 6, the movable member and the auxiliary member are brought into contact with each other on the way of the mountain-shaped inclined surface. At the time of leaving the hand at this point, the auxiliary member is always urged upward by the auxiliary spring 8, so that on the one hand, the oblique direction faces the X-direction of the mountain shape, and the side slides into 'but is held in a non-rotatable fixed position. Since the auxiliary member held by the member 4 cannot be rotated, on the one hand, the movable member is rotated in the Y direction, and the movable member is returned to the position where the movable member is engaged with the auxiliary member as shown in Fig. 5. In other words, even when the switching knob and the movable member are held at a position other than 90 degrees, they are automatically corrected to the engagement position of every 90 degrees, so the movable member and the fixed member must be held. In the positional relationship shown in Fig. 3 or Fig. 4 1309214. That is, the position where the movable member can be inserted into the fixed member can only be held at the position where the area of the abutting surface is the largest (the oblique line portion in Fig. 4), which is the impact on the road surface when the suspension function is locked. It can be guaranteed to be held at the maximum strength. Moreover, even if a special indexing mechanism is not provided, the structure itself has an indexing role, so that no additional parts are required, and the combination is troublesome.
並且,在可動構件與補助構件上做成不設置山形之凹凸 部5a,6a,而以平面抵接,藉由另外準備具有山形之構件及 彈簧時,在上下方向上可作動的狀態及上下方向上不可作動 的狀態之途中,亦可做成無法維持固定構件與可動構件之位 置關係。 並且,在本實施例中,雖然係在可動構件與補助構件之 2個構件上設置山形之凹凸部,但是,例如亦可將一方之構 件做山形,而將鋼球保持於另一方之構件上之時,亦可得到 同樣的效果,並且,如第7圖所示,在切換鈕1 0的側面上 設置凹部10a,將鋼球20以彈簧21彈壓而進入該凹部之時, 亦可得到同樣的效果,但是本實施例並不限於此,只要做成 在分度的途中無法保持的話即可。 並且,在本實施例中,雖然設置有每90度互相啣合的 山形之凹凸部或凹部,但是當然亦不限於90度。 又,在本發明中,爲了緩和在鎖住時來自路面的衝擊或 異音,於鎖住時在抵接的可動構件5之下部端面5d與固定 構件4之上部端面4a的間隙p中設置有緩衝構件1 2,具體 -10- 1309214 上如第2圖所示,在固定構件4之上部端面4a中設置有緩 衝構件1 2。在鎖住時,來自路面的衝擊被施加之時,可動構 件向固定構件的方向相對地移動,首先抵接於緩緩構件上, 其後緩緩構件被一定量壓縮之後,可動構件由固定構件而止 動’藉由完全地成爲鎖住之時,可緩和來自路面的衝擊或異 音0In addition, when the movable member and the auxiliary member are not provided with the mountain-shaped uneven portions 5a and 6a, and the surface is abutted, and the member having the mountain shape and the spring are separately prepared, the movable member can be moved in the vertical direction and the vertical direction. In the middle of the inoperable state, the positional relationship between the fixed member and the movable member cannot be maintained. Further, in the present embodiment, the mountain-shaped uneven portion is provided on the two members of the movable member and the auxiliary member. However, for example, one member may be formed in a mountain shape, and the steel ball may be held on the other member. At the same time, the same effect can be obtained. Further, as shown in Fig. 7, when the concave portion 10a is provided on the side surface of the switching knob 10, and the steel ball 20 is biased by the spring 21 and enters the concave portion, the same can be obtained. The effect of this embodiment is not limited to this, as long as it cannot be maintained in the middle of indexing. Further, in the present embodiment, although the convex portion or the concave portion of the mountain shape which is engaged with each other at 90 degrees is provided, it is of course not limited to 90 degrees. Further, in the present invention, in order to alleviate the impact or abnormal sound from the road surface at the time of locking, the gap p between the lower end surface 5d of the movable member 5 abutting and the upper end surface 4a of the fixing member 4 is provided in the lock. As shown in Fig. 2, the cushion member 1 2, specifically --10-30914, is provided with a cushioning member 12 in the upper end surface 4a of the fixing member 4. When the impact from the road surface is applied, the movable member relatively moves in the direction of the fixing member, first abutting on the slow member, and then the member is gradually compressed by a certain amount, and the movable member is fixed by the fixed member. And the stop 'when it is completely locked, it can alleviate the impact or abnormal sound from the road.
並且,即使緩衝構件1 2被設置於可動構件之下部端面 與固定構件之上部端面之時,同樣地亦可緩和衝擊,因而可 提高強度及耐久性。 〔發明之效果〕 習知上,大多數爲在匣式或懸吊前叉本身中將油封入, 藉由阻止油之流動而阻止上下方向之運動,因而鎖住懸吊功 能的構造之情形,因而以阻止油之流動而鎖住懸吊功能的構 造之情形,將油封入匣或懸吊前叉之中,甚至必須考慮密封 構造以消除漏油,因而必須非常地要求其精度,並且,雖然 必須有選擇鎖住狀態及鎖住釋放狀態的功能及構造,但是其 構造亦必須在空間非常狹窄的部分上,精度良好且表面完成 度佳者。即,在習知之阻止油之流動而鎖住懸吊功能的方法 中,成本變成非常高,生產量亦受限。 本發明係將這些問題一舉地解決,其係隨著懸吊功能之 鎖住機構的一般化,而以更低價格、更可大量生產,而且可 提供確實的鎖住機構之發明。 即,藉由:相對於不能轉動地安裝於懸吊前叉上的固定 構件,將可轉動地安裝的可動構件朝向上下方向可作動地設 -11- 1309214Further, even when the cushioning member 12 is provided on the end surface of the lower portion of the movable member and the end surface of the upper portion of the fixing member, the impact can be alleviated in the same manner, so that strength and durability can be improved. [Effects of the Invention] Conventionally, most of the construction is in which the oil is sealed in the shackle or the suspended front fork itself, and the movement of the oil is prevented from blocking the movement in the up and down direction, thereby locking the structure of the suspension function. Therefore, in the case of a structure that blocks the flow of the oil and locks the suspension function, the oil is sealed into the crucible or the suspended front fork, and even the sealing structure must be considered to eliminate the oil leakage, so the accuracy must be extremely required, and, although There must be a function and a structure to selectively lock the state and lock the release state, but the structure must also be in a very narrow space, with good precision and good surface finish. That is, in the conventional method of preventing the flow of oil and locking the suspension function, the cost becomes very high and the production amount is also limited. The present invention solves these problems in one fell swoop, and it is an invention of a reliable locking mechanism at a lower price and more mass production in accordance with the generalization of the locking mechanism of the suspension function. That is, by movably mounting the movable member rotatably mounted in the up and down direction with respect to the fixing member that is non-rotatably attached to the suspension fork -11 - 1309214
置,藉由選擇固定構件與可動構件之相對的位置關係之時, 可選擇在上下方向上作動可能的狀態,及在上下方向上作動 不可能的狀態’而可提供低價格、可大量生產的鎖住機構。By selecting the relative positional relationship between the fixed member and the movable member, it is possible to select a state that can be actuated in the up and down direction and a state in which it is impossible to operate in the up and down direction, and a low price and mass production can be provided. Lock the mechanism.
並且,藉由設置無法在途中保持固定構件與可動構件之 位置關係的分度機構之時,可提供安全且確實的鎖住機構, 並且’藉由在固定構件或可動構件的一方形成有凹凸部,將 在另一·方的構件上形成有與該凹凸部啣合的凹凸部之補助 構件被設置成不可能轉動,而在上下方向上可作動之時,並 不需要另外設置分度機構而可使固定構件與可動構件的位 置關係在途中無法保持’因此可提供更安全、低價格且確實 的鎖住機構。 並且,固定構件及可動構件的任一方之構件,係構成被 收容到另一方之構件的內徑側部中,藉由將該內徑部形狀做 成大略成蝴蝶結狀之時,使固定構件與可動構件之儘量地作 成大,在鎖住時可確保充分的強度,並且,藉由將衝擊緩衝 構件設置於固定構件端部及/或可動構件端部及/或固定構件 與可動構件之抵接面上之時,可緩和鎖住時受到的衝擊,因 此在強度面很有利,在鎖住時之感覺亦變成良好。 【圖式簡單說明】 第1圖係懸吊前叉的非鎖住狀態圖。 第2圖係懸吊前叉的鎖住狀態圖。 第3圖係非鎖住時之固定構件與可動構件的關係圖。 第4圖係鎖住時之固定構件與可動構件的關係圖。 第5圖係非鎖住狀態或鎖住狀態的內部構造放大圖。 1309214 第6圖係將可動構件從非鎖住狀態或鎖住狀態轉動4 5 * 度後的狀態圖。 第7圖係分度機構實施例。 【元件符號說明】 1 ...底殻 2 ...叉冠 3 a, 3 b ...叉管 4...固定構件 φ 5…可動構件 6.. .補助構件 7 ...補助彈簧承座 8.. .補助彈簧 9 ...螺絲 10.. .切換鈕 1 1 ...頂蓋 12.. .緩緩構件 ^ 1 3 ...固定螺栓 14.. .固定螺帽 15…套筒 16.. .叉桿 17.. .主彈簧 1 8 ...阻尼器 1 9 ...調整鈕 20…鋼球 21…彈簧 -13-Further, by providing an indexing mechanism that cannot maintain the positional relationship between the fixed member and the movable member on the way, a safe and reliable locking mechanism can be provided, and 'the uneven portion is formed on one of the fixed member or the movable member. The auxiliary member formed with the uneven portion that is engaged with the concave-convex portion on the other member is set to be impossible to rotate, and when it is movable in the up-and-down direction, it is not necessary to additionally provide an indexing mechanism. The positional relationship between the fixed member and the movable member can be prevented from being maintained on the way' thus providing a safer, less expensive and reliable locking mechanism. Further, any one of the fixing member and the movable member is configured to be housed in the inner diameter side portion of the other member, and when the inner diameter portion is formed into a substantially bow shape, the fixing member and the fixing member are The movable member is made as large as possible, and sufficient strength is secured when locked, and the shock absorbing member is disposed at the end of the fixing member and/or the end of the movable member and/or the abutment of the fixed member with the movable member When it is on the surface, it can alleviate the impact when it is locked, so it is advantageous in the strength surface, and the feeling when it is locked becomes good.
