Description
本發明係關於緩衝裝置，尤指一種用以緩衝門窗等開閉體在開閉時之衝擊之緩衝裝置。The present invention relates to a cushioning device, and more particularly to a cushioning device for buffering an impact of an opening and closing body such as a door or window during opening and closing.
以往，用以緩衝吸收門窗等開閉體在開閉時之衝擊力之緩衝裝置已有例如，活塞阻尼器廣為使用。使用此種裝置時，必需使用緩衝開閉體開啟時所生衝擊用之活塞阻尼器，及緩衝開閉體關閉時所生衝擊用之活塞阻尼器之二個一組之阻尼器。又，專利文獻一中揭示有一種作動桿本體係由沿軸向排列之第一作動桿及第二作動桿，以及將此等第一作動桿與第二作動桿連結成可沿軸向伸縮移動自如之伸縮機構部所構成，而伸縮機構部具有一設在第一作動桿及第二作動桿二者中之一作動桿之桿端之活塞筒，及一設在另一作動桿之桿端且可藉由一滑動體可沿軸向之預定範圍內前後滑動自如的密嵌於該活塞筒內之活塞所構成。Conventionally, a cushioning device for absorbing an impact force that absorbs an opening and closing body such as a door or window during opening and closing has been widely used, for example, as a piston damper. When such a device is used, it is necessary to use a piston damper for shock generated when the buffer opening and closing body is opened, and a damper for two groups of piston dampers for shocking when the opening and closing body is closed. Further, in Patent Document 1, there is disclosed an actuating lever system in which an axially arranged first actuating lever and a second actuating lever are coupled, and the first actuating lever and the second actuating lever are coupled to be axially extendable and movable. The telescopic mechanism portion is configured to have a piston tube disposed at one of the first actuating lever and the second actuating lever, and a rod end disposed at the rod end of the other actuating lever And the sliding body can be formed by a piston which is slidably and slidably embedded in the piston cylinder in a predetermined range in the axial direction.
[專利文獻一：日本特開2009-275746][Patent Document 1: Japanese Special Opening 2009-275746]
然而，使用上述緩衝裝置做為緩衝及吸收門窗等開閉體之緩衝裝置時，因必需使用開及閉之二組阻尼器，所佔用之安裝空間頗大。至於使用專利文獻一之緩衝裝置時，則必需將第一作動桿及第二作動桿連結於被安裝體及安裝於被安裝體之開閉體，因此開閉體之開放量(開放口)受到作動桿之行程之限制，而不利使用。However, when the above-mentioned cushioning device is used as a buffering device for buffering and absorbing opening and closing bodies such as doors and windows, it is necessary to use two sets of dampers that open and close, and the occupied installation space is considerable. When the cushioning device of Patent Document 1 is used, it is necessary to connect the first actuating lever and the second actuating lever to the mounted body and the opening and closing body attached to the mounted body. Therefore, the opening amount (opening port) of the opening and closing body is actuated by the actuating lever. The limitations of the itinerary are not useful.
本發明有鑑於上述事實，為解決其問題而開發者。本發明之目的在提供一種整體構成緊湊，可減少裝置之安裝空間之緩衝裝置。The present invention has been made in view of the above facts in order to solve the problem. SUMMARY OF THE INVENTION An object of the present invention is to provide a cushioning device which is compact in overall construction and which can reduce the installation space of the apparatus.
請求項1所述本發明之緩衝裝置，具有：一緩衝機構，其係由一外周部設有活塞筒停止部之活塞筒，一可往復活動的插設在該活塞筒內之活塞，一連結於該活塞且外周部設有活塞桿停止部之活塞桿，及一設於上述活塞筒內而賦與上述活塞有經常推壓該活塞桿向伸出活塞筒外部之方向移動之能量之彈簧所構成；一緩衝機構支持構件，用以容納並保持上述緩衝機構，以便使之於受到外部負載時能沿負載作用之方向移動；一活塞筒停止部止動部，設於上述緩衝機構支持構件上之沿上述緩衝機構移動方向之一端部，而可抵住上述活塞筒停止部以擋止上述活塞筒之移動，而得以保持活塞筒之一端部突出上述緩衝機構支持構件之外部之狀態；一活塞桿停止部止動部，設於上述緩衝機構支持構件上之沿上述緩衝機構移動方向之另一端部，而可抵住上述活塞桿停止部以擋止上述活塞桿之移動，而得以保持活塞桿之一端部突出上述緩衝機構支持構件之外部之狀態。The shock absorber of the present invention according to claim 1 has a buffer mechanism which is a piston cylinder having a piston cylinder stop portion on an outer peripheral portion, and a piston reciprocally inserted in the piston cylinder, a connection a piston rod having a piston rod stopping portion on the outer circumference of the piston, and a spring disposed in the piston cylinder to impart energy for moving the piston rod to a direction extending outward from the piston tube a buffer mechanism supporting member for accommodating and holding the buffer mechanism so as to be movable in a direction of load action when subjected to an external load; a cylinder stop stop portion disposed on the buffer mechanism supporting member One end of the buffer mechanism moving direction can be pressed against the cylinder stop portion to block the movement of the cylinder, thereby maintaining one end of the cylinder protruding from the outside of the buffer mechanism supporting member; a piston The rod stop portion stopper portion is provided on the other end portion of the buffer mechanism supporting member in the moving direction of the buffer mechanism, and is capable of abutting against the piston rod stopping portion In order to stop the movement of the piston rod, it is possible to maintain the state in which one end of the piston rod protrudes outside the cushioning mechanism supporting member.
依請求項1所述之緩衝裝置，其緩衝機構係可沿外力負載之作用方向移動的容設於緩衝機構支持構件內，因此，當該緩衝機構之突出緩動機構支持構件之活塞筒之一端受到負載作用時，緩衝機構即對緩衝機構支持構件順著負載之作用方向移動。此時，活塞桿之前端外周部所設活塞桿停止部會抵住緩衝機構支持構件之沿緩衝機構移動方向一端所設活塞桿停止部止動部，而保持活塞桿之一端部伸出緩衝機構支持構件外部之狀態止住活塞桿繼續移動，結果，活塞筒可相對於滑動自如的插設於活塞筒內之活塞所連接之活塞桿，抗著彈簧之推壓力往壓縮方向移動，由於活塞筒內所生高壓阻抗力可緩和作用於活塞筒側之衝擊力。According to the buffer device of claim 1, the buffer mechanism is movable in the direction of the external force load and is accommodated in the buffer mechanism supporting member. Therefore, when the buffer mechanism protrudes from the one end of the piston tube of the supporting member When subjected to a load, the buffer mechanism moves the buffer mechanism support member in the direction in which the load acts. At this time, the piston rod stopping portion provided at the outer peripheral portion of the front end of the piston rod abuts the piston rod stopping portion stopper portion provided at one end of the buffer mechanism supporting member in the moving direction of the buffer mechanism, and holds one end portion of the piston rod out of the buffer mechanism. The state outside the support member stops the piston rod from moving, and as a result, the piston rod is movable relative to the piston rod connected to the piston that is slidably inserted in the piston cylinder against the pressing force of the spring, due to the piston barrel The high-pressure resistance generated inside can alleviate the impact force acting on the cylinder side.
另一方面，當該緩衝機構之突出緩動機構支持構件之活塞桿之一端受到負載作用時，緩衝機構即對緩衝機構支持構件順著負載之作用方向移動。此時，活塞筒之一端外周部所設活塞筒停止部會抵住緩衝機構支持構件之沿緩衝機構移動方向另一端所設活塞筒停止部止動部，而保持活塞筒之一端部伸出緩衝機構支持構件外部之狀態止住活塞筒繼續移動，結果，可滑動自如的插設於活塞筒內之活塞所連接之活塞桿，即相對於活塞筒，抗著彈簧之推壓力往壓縮方向移動，由於活塞筒內所生高壓阻抗力可緩和作用於活塞桿側之衝擊力。On the other hand, when one end of the piston rod of the protruding easing mechanism supporting member of the damper mechanism is subjected to a load, the damper mechanism moves the buffer mechanism supporting member in the direction in which the load acts. At this time, the piston tube stopping portion provided at the outer peripheral portion of one end of the piston cylinder abuts the piston tube stopping portion stopper portion provided at the other end of the buffer mechanism supporting member in the moving direction of the buffer mechanism, and holds one end of the piston tube out of the buffer. The state outside the mechanism supporting member stops the piston cylinder from moving, and as a result, the piston rod that is slidably inserted into the piston in the piston cylinder is moved relative to the piston cylinder against the pressing force of the spring. The high-voltage resistance force generated in the cylinder can alleviate the impact force acting on the piston rod side.
因此，祇使用一個緩衝機構便可緩和活塞桿側所發生之衝擊及活塞筒側所發生之衝擊。於是，與習知需使用二個緩衝裝置來達成之情形比較，可減小緩衝裝置之安裝空間。Therefore, only one buffer mechanism can be used to alleviate the impact on the piston rod side and the impact on the cylinder side. Thus, the installation space of the buffer device can be reduced as compared with the case where it is conventionally required to use two buffer devices.
請求項2所述之發明為依據請求項1所述之緩衝裝置，其中該活塞筒停止部係形成於上述活塞筒之外周壁之小徑部與大徑部之段差部，而該活塞筒之小徑部係從上述緩衝機構支持構件向外突出。The invention according to claim 2, wherein the cylinder stop portion is formed in a stepped portion of the small diameter portion and the large diameter portion of the outer peripheral wall of the piston cylinder, and the cylinder tube The small diameter portion protrudes outward from the buffer mechanism supporting member.

依請求項3所述之緩衝裝置，因該活塞桿停止部係形成突緣部，且具有連動於突緣部之滑動構件自緩衝機構支持構件之一端向外突出，於是，可藉簡單之構成使活塞桿之一端自緩衝機構支持構件確實向外突出，並提高緩衝裝置之生產性。According to the buffer device of claim 3, the piston rod stopping portion forms a flange portion, and the sliding member having the flange portion is protruded outward from one end of the buffer mechanism supporting member, so that the simple structure can be utilized.

茲參照第一圖及第二圖就本發明一實施形態之緩衝裝置詳細說明如下。圖中，箭頭FR表示緩衝裝置之前方方向，箭頭UP表示緩衝裝置之上方方向。The buffer device according to an embodiment of the present invention will be described in detail below with reference to the first and second drawings. In the figure, an arrow FR indicates the front direction of the buffer device, and an arrow UP indicates the upward direction of the buffer device.
如第一圖及第二圖所示，本實施形態之緩衝裝置10，主要包括一做為緩衝機構之活塞阻尼器12及一用以收容此活塞阻尼器12之做為緩衝機構支持構件之外殼14之二組件。活塞阻尼器12係可沿負載之作用方向(第一圖之箭頭C及D方向)亦即活塞阻尼器12之軸線方向(第一圖之箭頭A及B方向)往復滑動的嵌設於外殼14內部。As shown in the first and second figures, the buffer device 10 of the present embodiment mainly includes a piston damper 12 as a buffer mechanism and a housing for receiving the piston damper 12 as a buffer mechanism supporting member. 14 bis component. The piston damper 12 is reciprocally slidably embedded in the outer casing 14 along the direction of action of the load (arrows C and D in the first figure), that is, the axial direction of the piston damper 12 (arrows A and B in the first figure). internal.
如第一圖所示，外殼4具有內部形成圓筒形空間15之本體部14A，及形成於本體部14A上部之安裝部14B。又，如第二圖所示，外殼14之安裝部14B之寬度方向(第二圖之箭頭W1方向)之兩端部形成自本體部14A向寬度方向外側突出之突出緣狀結合部14C，外殼14可藉此安裝部14B之結合部14C利用螺釘等固定部件(圖示省略)或黏著劑等固定於開閉體之支持部。As shown in the first figure, the outer casing 4 has a body portion 14A in which a cylindrical space 15 is formed, and a mounting portion 14B formed on an upper portion of the body portion 14A. Further, as shown in the second figure, both end portions of the attachment portion 14B of the outer casing 14 in the width direction (the direction of the arrow W1 in the second diagram) are formed with protruding flange-like joint portions 14C projecting outward from the main body portion 14A in the width direction, and the outer casing The joint portion 14C of the attachment portion 14B can be fixed to the support portion of the opening and closing body by a fixing member (not shown) such as a screw or an adhesive or the like.
如第一圖所示，外殼14之本體部14A沿活塞阻尼器12之移動方向之一端形成有活塞筒停止部止動部14D，此活塞筒停止部止動部14D之中央設有圓形貫通孔16。As shown in the first figure, the main body portion 14A of the outer casing 14 is formed with a cylinder stop stop portion 14D at one end of the movement direction of the piston damper 12, and a circular through hole is formed in the center of the cylinder stop portion 14D. Hole 16.
此外，外殼14之本體部14A沿活塞阻尼器12之移動方向之另一端形成有活塞桿停止部止動部14E，此活塞桿停止部止動部14E之中央設有圓形貫通孔18。Further, the main body portion 14A of the outer casing 14 is formed with a piston rod stopping portion stopper portion 14E at the other end in the moving direction of the piston damper 12, and a circular through hole 18 is provided at the center of the piston rod stopping portion stopper portion 14E.
活塞阻尼器12係由圓筒狀之活塞筒20、插設於活塞筒20之內部而可沿活塞筒20之軸向滑動自如之活塞22、連結於活塞22之一端之活塞桿24、及設於活塞筒20內部之彈簧26所構成。彈簧26之一端抵住活塞筒20之端面20C內壁，另一端則抵住活塞22之另一端面以賦予活塞桿24有經常被推向活塞筒20外側方向(即向箭頭B方向)移動之趨勢之能量。又，活塞筒20之內部宜注滿阻尼油脂等，使活塞阻尼器12在活塞桿24與活塞筒20進行壓縮方向之相對移動時產生阻尼、緩衝之作用。The piston damper 12 is a cylindrical piston cylinder 20, a piston 22 that is inserted into the piston cylinder 20 and slidable along the axial direction of the cylinder barrel 20, and a piston rod 24 that is coupled to one end of the piston 22, and The spring 26 is formed inside the piston barrel 20. One end of the spring 26 abuts against the inner wall of the end surface 20C of the cylinder barrel 20, and the other end abuts against the other end surface of the piston 22 to give the piston rod 24 a direction which is often pushed toward the outside of the cylinder barrel 20 (i.e., in the direction of arrow B). The energy of the trend. Further, the inside of the cylinder barrel 20 should be filled with damping grease or the like to cause the piston damper 12 to act as a damping and buffering force when the piston rod 24 and the cylinder barrel 20 are relatively moved in the compression direction.
活塞筒20之外周部沿軸向一段距離之略中間部形成有一段差部30做為活塞筒停止部，此段差部30係形成於活塞筒20之活塞桿24***端之大徑部20A與相反端之小徑部20B之交界處，大徑部20A之外徑比小徑部20B之外徑粗大而形成突緣狀。A portion of the outer peripheral portion of the cylinder barrel 20 is formed with a step portion 30 as a cylinder stop portion at a slight intermediate portion of the axial direction. The step portion 30 is formed at the large diameter portion 20A of the insertion end of the piston rod 24 of the piston barrel 20 and vice versa. At the junction of the small-diameter portion 20B of the end, the outer diameter of the large-diameter portion 20A is thicker than the outer diameter of the small-diameter portion 20B to form a flange shape.
又，段差部30於活塞筒20相對於外殼14向後方(即第一圖之箭頭A方向)移動時，最後會抵住外殼14之活塞筒停止部止動部1414D，因此，活塞筒20之段差部30抵住外殼14之活塞筒停止部止動部14D後，活塞筒20之向箭頭A方向之移動部即停止。又，在停止狀態下，活塞筒20之小徑部20B則從外殼14之活塞筒停止部止動部14D向外伸出所定長度如第一圖所示。Further, when the cylinder barrel 20 moves rearward relative to the outer casing 14 (ie, the direction of the arrow A in the first figure), the step portion 30 finally abuts against the cylinder stop portion stopper portion 1414D of the outer casing 14, and therefore, the cylinder barrel 20 When the step portion 30 abuts against the cylinder stop portion stopper portion 14D of the outer casing 14, the moving portion of the piston tube 20 in the direction of the arrow A is stopped. Further, in the stopped state, the small diameter portion 20B of the piston barrel 20 projects outward from the cylinder stop portion stopper portion 14D of the outer casing 14 as shown in the first figure.
又，自活塞筒20之段差部30至小徑部20B一端之延伸段相距一所定距離之中途部位設有環狀凸部32。Further, an annular convex portion 32 is provided from a portion of the stepped portion 30 of the piston cylinder 20 to an extending portion of one end of the small-diameter portion 20B at a distance from a predetermined distance.
另一方面，活塞桿24之外周部之軸向中途部位形成有突緣34做為活塞桿停止部。又，活塞桿24之自突緣34起之前方部位設有構成活塞桿24之一部份之滑動構件36。具體而言，滑動構件36之基部36A與突緣34連成一體，如此，滑動構件36可與活塞桿24同步連動。又，滑動構件36之中間部36B穿通外殼14之活塞桿停止部止動部14E上所形成之貫通孔18，滑動構件36之前端部36C則形成圓盤狀。滑動構件36如與活塞桿24個別形成後再組裝成一體，亦可行。在此情形時，滑動構件36之基部36A係可離合的安裝於活塞桿24之突緣34一端相面對，當活塞桿24前進而碰接滑動構件36並推壓往第一圖箭頭B方向時，滑動構件36即與活塞桿24連成一體向前移動，為使滑動構件36之基部36A不致脫離貫通孔18，滑動構件36之基部36A應形成直徑大於貫通孔18之圓盤狀擋止部。On the other hand, a flange 34 is formed as a piston rod stop portion at a midway portion of the outer peripheral portion of the piston rod 24. Further, the piston rod 24 is provided with a sliding member 36 constituting a part of the piston rod 24 from the front side of the flange 34. Specifically, the base portion 36A of the sliding member 36 is integrally formed with the flange 34 such that the sliding member 36 can be synchronized with the piston rod 24. Further, the intermediate portion 36B of the sliding member 36 passes through the through hole 18 formed in the piston rod stopping portion stopper portion 14E of the outer casing 14, and the front end portion 36C of the sliding member 36 is formed in a disk shape. The sliding member 36 is integrally formed with the piston rod 24 and then assembled into a single body. In this case, the base portion 36A of the sliding member 36 is detachably attached to one end of the flange 34 of the piston rod 24, and when the piston rod 24 advances, it abuts against the sliding member 36 and pushes the arrow B direction of the first figure. When the sliding member 36 is integrally moved forward with the piston rod 24, in order to prevent the base portion 36A of the sliding member 36 from coming off the through hole 18, the base portion 36A of the sliding member 36 should form a disc-shaped stop having a diameter larger than the through hole 18. unit.
又，活塞桿24之突緣34在活塞桿24相對於外殼14向前方(第一圖之箭頭B方向)移動時，最後會抵接活塞桿停止部止動部14E。突緣34一抵接活塞桿停止部止動部14E即受阻而停止向前方移動，在此狀態下，與活塞桿24連動之滑動構件36即自外殼14之活塞桿停止部止動部14E伸出前方外側所定長度。Further, when the piston rod 24 moves forward with respect to the outer casing 14 (in the direction of the arrow B in the first figure), the flange 34 of the piston rod 24 finally abuts against the piston rod stopping portion stopper portion 14E. When the flange 34 abuts against the piston rod stopping portion stopper portion 14E, it is blocked and stops moving forward. In this state, the sliding member 36 that is interlocked with the piston rod 24 is extended from the piston rod stopping portion stopper portion 14E of the outer casing 14. The length of the front outer side is determined.
因此，在第一圖所示狀態下，突出外殼14之活塞筒停止部止動部14D外部之活塞筒20之小徑段前端部20C如受到外力(即負載)被推壓向前方(第一圖箭頭C方向)時，阻尼器12之活塞筒20即相對於固定在支持構件之外殼14沿第一圖箭頭B方向移動，但活塞桿24之突緣34因抵住外殼14之活塞桿停止部止動部14E而不會再沿第一圖箭頭B方向移動之故，繼續移動之活塞筒20便相對於活塞桿24往壓縮方向(第一圖箭頭B方向)移動，由於活塞筒20內部壓力上昇而可緩衝作用於活塞筒20之前端部20C之衝擊力。Therefore, in the state shown in the first figure, the small-diameter end portion 20C of the piston barrel 20 outside the cylinder stopper stop portion 14D of the protruding casing 14 is pushed forward by an external force (i.e., load) (first In the direction of arrow C, the piston barrel 20 of the damper 12 is moved in the direction of arrow B of the first figure with respect to the outer casing 14 fixed to the support member, but the flange 34 of the piston rod 24 is stopped by the piston rod against the outer casing 14. The portion of the piston barrel 20 is moved in the compression direction (the direction of the arrow B in the first figure) with respect to the piston rod 24, so that the portion of the piston tube 20 is moved in the direction of the arrow B in the first figure. The pressure rises to cushion the impact force acting on the front end portion 20C of the cylinder barrel 20.
一方面，在第一圖所示狀態下，突出外殼14之活塞桿停止部止動部14E外部之滑動構件36之前端部36C如受到外力被推壓向後方(第一圖箭頭D方向)時，活塞桿24即相對於固定在支持構件之外殼14沿第一圖箭頭D方向移動，但活塞筒20之段差部30因抵住活塞筒停止部止動部14D而不會再沿第一圖箭頭A方向(即向後方)移動之故，繼續移動之活塞桿24便相對於活塞筒20往壓縮方向(第一圖箭頭A方向)移動，由於活塞筒20內部壓力上昇而可緩衝作用於滑動構件36之前端部36C之衝擊力。On the other hand, in the state shown in the first figure, the front end portion 36C of the sliding member 36 outside the piston rod stopping portion stopper portion 14E of the protruding casing 14 is pushed rearward by the external force (in the direction of the arrow D in the first figure). The piston rod 24 moves in the direction of the arrow D in the first figure with respect to the outer casing 14 fixed to the supporting member, but the step portion 30 of the cylinder barrel 20 does not follow the first figure due to the cylinder stop portion 14D. When the arrow A moves (i.e., to the rear), the piston rod 24 that continues to move moves in the compression direction (the direction of the arrow A in the first figure) with respect to the cylinder 20, and the buffer acts on the sliding due to the pressure inside the cylinder 20 rises. The impact of the front end 36C of the member 36.
以下，就本實施形態之緩衝裝置之作用及功效詳細說明：依上述構成之緩衝裝置10，當其突出外殼14之活塞桿停止部止動部14E外部之活塞筒20之前端部20C受到外力(負載)作用而向第一圖箭頭C方向移動時，活塞筒20即相對於固定在支持構件之外殼14沿第一圖箭頭C方向移動，但此時，活塞桿24之突緣34抵住活塞筒停止部止動部14D而不會再沿第一圖箭頭A方向(即向後方)移動之故，繼續移動之活塞桿24便相對於活塞筒20往壓縮方向(第一圖箭頭A方向)移動，由於活塞筒20內部壓力上昇而可緩衝作用於滑動構件36之前端部36C之衝擊力。Hereinafter, the action and the effect of the damper device of the present embodiment will be described in detail. According to the above-described damper device 10, the front end portion 20C of the piston tube 20 outside the piston rod stop portion stopper portion 14E of the projecting casing 14 is subjected to an external force ( When the load acts to move in the direction of the arrow C of the first figure, the piston barrel 20 moves in the direction of the arrow C of the first figure with respect to the outer casing 14 fixed to the supporting member, but at this time, the flange 34 of the piston rod 24 abuts against the piston. The cylinder stop portion stopper portion 14D does not move further in the direction of the arrow A in the first figure (that is, toward the rear), so that the piston rod 24 that continues to move is compressed in the compression direction with respect to the cylinder barrel 20 (the direction of the arrow A in the first figure). When moving, the impact force acting on the front end portion 36C of the sliding member 36 can be buffered due to an increase in the internal pressure of the piston barrel 20.
一方面，當突出外殼14之活塞桿停止部止動部14E外部之活塞筒20之前端部36C受到外力(負載)作用而向第一圖箭頭D方向移動時，活塞桿24即相對於固定在支持構件之外殼14沿第一圖箭頭C方向移動，但此時，活塞桿24之突緣34抵住活塞筒停止部止動部14D而不會再沿第一圖箭頭A方向(即向後方)移動之故，繼續移動之活塞桿24便相對於活塞筒20往壓縮方向(第一圖箭頭A方向)移動，由於活塞筒20內部壓力上昇而可緩衝作用於滑動構件36之前端部36C之衝擊力。On the one hand, when the front end portion 36C of the piston tube 20 outside the piston rod stop portion 14E of the protruding casing 14 is subjected to an external force (load) to move in the direction of the arrow D of the first figure, the piston rod 24 is fixed relative to The outer casing 14 of the supporting member moves in the direction of the arrow C of the first figure, but at this time, the flange 34 of the piston rod 24 abuts against the cylinder stopping portion stopper portion 14D and is no longer in the direction of the arrow A of the first figure (ie, rearward) The movement of the piston rod 24 that continues to move is moved relative to the cylinder barrel 20 in the compression direction (the direction of the arrow A in the first figure), and the pressure acting on the front end portion 36C of the sliding member 36 can be buffered due to the pressure rise inside the cylinder barrel 20. impact.
因此，本實施形態，僅使用一個緩衝裝置10，即可用來緩衝發生在活塞桿24端之衝擊力及發生在活塞筒20端之衝擊力，亦即一個緩衝裝置10可用於前及後雙向之緩衝，於是，與使用二個緩衝裝置之習知技術相比，可減少緩衝裝置所需佔用之安裝空間。Therefore, in this embodiment, only one buffer device 10 can be used to buffer the impact force occurring at the end of the piston rod 24 and the impact force occurring at the end of the cylinder barrel 20, that is, one buffer device 10 can be used for both front and rear directions. Buffering, thus, the installation space required for the cushioning device can be reduced as compared with the prior art using two cushioning devices.
又，本實施形態，因活塞筒停止部係形成於上述活塞筒之外周壁之小徑部與大徑部之段差部，而該活塞筒之小徑部係從上述緩衝機構支持構件向外突出之構造，於是，可藉簡單之構造將活塞筒容設於緩衝機構支持構件內並使其一端突出外部，遂可提高緩衝裝置之生產性。Further, in the present embodiment, the piston cylinder stopping portion is formed in a stepped portion of the small diameter portion and the large diameter portion of the outer peripheral wall of the piston cylinder, and the small diameter portion of the piston cylinder protrudes outward from the buffer mechanism supporting member. Therefore, the piston cylinder can be accommodated in the cushioning mechanism supporting member by a simple structure and one end thereof can be protruded to the outside, and the productivity of the cushioning device can be improved.
又，本實施形態，因活塞筒停止部係形成突緣部，且具有連動於突緣部之滑動構件自緩衝機構支持構件之一端向外突出，於是，可藉簡單之構成使活塞桿之一端自緩衝機構支持構件確實向外突出，並提高緩衝裝置之生產性。Further, in the present embodiment, the flange portion is formed by the piston cylinder stopping portion, and the sliding member that is interlocked with the flange portion protrudes outward from one end of the buffer mechanism supporting member, so that one end of the piston rod can be simply constituted The self-buffering mechanism support member does protrude outward and improves the productivity of the cushioning device.

That is, the inside of the outer casing 14 is pushed in, so that the piston cylinder 20 moves in the compression direction (the direction of the arrow B in the first figure) with respect to the piston rod 24, and the impact force acting on the front end portion 20C of the cylinder barrel 20 when the sliding door 42 is closed can be buffered. . On the other hand, as shown in the fifth figure, when the sliding door 42 approaches the door opening position, the front end portion 36C of the sliding member 36 abuts the door side vertical frame 40A of the door frame 40, the stopper portion 50B of the stopper 50, and the sliding member. 36 is pushed into the outer casing 14 in the direction of the arrow D of the fifth figure, so that the piston rod 24 moves toward the compression direction of the piston cylinder 20 (the direction of the arrow A in the first figure), and the function of the sliding door 42 to open the door can be buffered. The impact force on the front end portion 36C of the sliding member 36.
