A simple, small double-opening door closer that can hold the door closer body in the door. The present invention also relates to a double-opening door closer in which the braking structure is combined, and a freedom capable of temporarily stopping the opening and closing operation of the door in the middle of the door from the 0 o'clock position to an open position above 90 degrees left and right is combined. Double-opening door closer with stop mechanism. (2) In the prior art, as a door hinge device for supporting double-open doors provided at the entrances of various stores, a hinge in a top hinge device such as buried in a ceiling and a hinge in a bottom hinge buried in a floor are generally used. Door hinge device to support the door with a shaft. The existing double-opening doors that open in both directions are mainly in the form of being buried in the floor, so the necessity of construction and the inconvenience due to rain and cleaning require cleaning agents. Problems often occur. In addition, the existing double-hinged door hinge devices also use spring-type door closers, but they are all devices that only close the door by the force of a spring, so there is a danger of a sudden opening and closing operation. In addition, the current center-hanging door closer -6-200417671 cannot be made into a double-opening structure because it determines the way to open the door left and right according to the spring tightening direction and the cutting direction of the piston bolt. It also causes problems. From this point of view, a double-open spring-type door closer that has a relatively simple structure, can be miniaturized, and has a small number of exposed portions during installation and has a good appearance is also recently proposed (Patent Document 1). In addition, another device such as a bumper hinge that uses oil pressure to adjust the closing speed of the door to brake and absorb the closing force of the door has also been proposed (Patent Document 2).

The upper and lower stoppers 1 06 and 1 07 of 1 04 can be rotated within a predetermined angle range. The upper end of the coil spring 108 is fixed to the upper stop member 106, and the lower end of the coil spring 108 is fixed to the lower upper member 107. A stopper pin 103b protruding from the inside of the mounting plate 103 covering the upper portion of the main body housing 102 is connected to a stopper portion 106b of the upper stopper member 106, and is protruded from the bottom plate 105 of the main body housing 102. The stopper pin 105b is connected to the stopper portion 107b of the stopper member 107 on the lower side. In addition, such spring-loaded door closers 010 are installed by burying the main body casing in the upper and lower portions of the door, and fixing their mounting plates. Among the joint fittings on the floor side, the projecting end of the rotating shaft is fitted and fixed, and is installed and used. For this reason, since this spring-type door closer only has a coil spring and a stopper member installed around the rotation shaft, its structure is simple and can be made into a small structure, so it can be installed into the interior of the entry door, and its appearance is not attractive. Eye-catching, can be effectively used for door hinges of double-opening doors. However, in order to make use of the potential energy of the coil spring, the above-mentioned door closer can give potential energy to the door in the locking direction, and in order to realize the automatic closing of the door, there is no braking part when the door is closed. In order to solve such a problem, it is now necessary to use a buffer mechanism in addition to such a door closer. However, the spring-type shock absorber mechanism described in the above-mentioned Patent Document 2 can only use a single-opening door, and is not suitable for a double-opening application.

上述圓筒21的內部形成有由圓筒基座24和圓筒底蓋22 形成的油室2 7,該油室2 7的內部被充滿油。油室2 7中, 配置有將油室27劃分爲上部室28和下部室29的活塞螺栓 30,該活塞螺栓30被做成圓筒形,上述活塞螺栓30的外 圓周與上述圓筒2 1的內表面通過螺旋相結合,上述緩衝器 軸1 7以非旋轉、且具有油的流路的方式通過栓槽結合在上 述活塞螺栓3 0的上部,此外,上述活塞螺栓3 0的下部被 固定有閥座30A、該閥座30A中設置有如圖所示那樣根據 門的開啓動作在當活塞螺栓3 0向上方移動時能使油迅速 地從上部室2 8移動到下部室2 9中的止回閥3 1 (本例中爲球 閥)。此外,活塞螺栓3 0和緩衝器軸1 7之間,如第5圖所 示那樣,形成有連通上部室28和下部室29的流路(油逃逸 溝)32。 上述活塞螺栓3 G和緩衝器軸丨7通過鋸齒被結合在一起 ,該活塞螺栓3 0沿鋸齒上下移動。通過這種構成,例如, -16- 200417671 緩衝器軸1 7在非旋轉狀態時若筒體1 5旋轉的話,則與筒 體15組成爲一體的圓筒21便旋轉,並且與圓筒21的內表 面螺旋結合的活塞螺栓3 0通過圓筒2 1的旋轉以非旋轉的 狀態向上方移動。另外,如果與筒體1 5成一體的圓筒2 1 處於非旋轉狀態而緩衝器軸1 7旋轉的話,與緩衝器軸i 7 通過鋸齒結合的活塞螺栓3 0便與緩衝器軸1 7成一體地旋 轉,由此,螺旋連接在圓筒2 1中的活塞螺栓3 〇便使經鋸 齒結合的緩衝器軸1 7向上方移動。 此外,活塞螺栓30的上述閥座30A的中央部中貫通有調 _ 速棒2,該調速棒2貫通活塞螺栓3 0的閥座3 0 A的部分被 形成爲錐形(本例中形成爲從下方一側向上方一側依次減 少直徑的錐形形狀)。從而將設置在上述門框側固定部件1 的一側的調速齒輪3 b轉動,且經過設置在輸出軸1 e內部 的調速齒輪3 a將調速棒2轉動,這樣能使門框側固定部件 1的輸出軸1 e上經螺旋結合的調速棒2相對於活塞螺栓3 〇 上下移動,由此,活塞螺栓3 0上形成的貫通孔和調速棒2 之間的間隙可通過調速棒2的錐形部加以調節,也可以調 % 節該間隙部分的流路面積。此外,調速棒2和緩衝器軸1 7 之間設置有密封件3 3,能防止油室27的油流入孔i b內。 另外,調速棒2的上下移動並不限於螺旋方式,也可以採 用手動提升調整等其他手段。此外,36、37爲用來對圓筒 2 1的外圓周和活塞螺栓3 0的外圓周進行密封的密封件和 保護件。3 8爲緩衝器軸1 7的軸止動輪。 以下說明上述結構的雙開式關門器的動作。 -17- 200417671 在門關閉狀態時,內輪1 0、外輪9位於第7圖(b)所示的 0點靜止位置上。An oil chamber 27 formed by the cylinder base 24 and the cylinder bottom cover 22 is formed inside the cylinder 21, and the inside of the oil chamber 27 is filled with oil. The oil chamber 27 is provided with a piston bolt 30 that divides the oil chamber 27 into an upper chamber 28 and a lower chamber 29. The piston bolt 30 is formed in a cylindrical shape. The outer circumference of the piston bolt 30 and the cylinder 21 are arranged. The inner surfaces of the piston bolts are connected by a screw. The bumper shaft 17 is coupled to the upper portion of the piston bolt 30 through a bolt groove in a non-rotating and oil flow path manner. In addition, the lower portion of the piston bolt 30 is fixed. There is a valve seat 30A, and the valve seat 30A is provided with a stop according to the opening operation of the door as shown in the figure, which can quickly move the oil from the upper chamber 28 to the lower chamber 29 when the piston bolt 30 moves upward. Check valve 3 1 (ball valve in this example). A flow path (oil escape groove) 32 communicating between the upper chamber 28 and the lower chamber 29 is formed between the piston bolt 30 and the bumper shaft 17 as shown in FIG. 5. The above-mentioned piston bolt 3 G and the buffer shaft 丨 7 are combined together by a saw tooth, and the piston bolt 30 moves up and down along the saw tooth. With this configuration, for example, when -16-200417671 buffer shaft 17 is in a non-rotating state, if the cylinder 15 is rotated, the cylinder 21 integrated with the cylinder 15 is rotated, and The internally spirally connected piston bolt 30 moves upward in a non-rotating state by rotation of the cylinder 21. In addition, if the cylinder 2 1 integrated with the cylinder 15 is in a non-rotating state and the bumper shaft 17 is rotated, the piston bolt 30 connected to the bumper shaft i 7 by a serration will become 70% of the bumper shaft 17. By integrally rotating, the piston bolt 3 screwed in the cylinder 21 moves the bumper shaft 17 which is serrated together upward. In addition, in the central portion of the valve seat 30A of the piston bolt 30, a speed regulating rod 2 is penetrated, and a portion of the speed regulating rod 2 penetrating the valve seat 3 0 A of the piston bolt 30 is tapered (formed in this example) It has a tapered shape with a decreasing diameter from the lower side to the upper side.) Thus, the speed regulating gear 3 b provided on one side of the door frame side fixing member 1 is rotated, and the speed regulating rod 2 is rotated through the speed regulating gear 3 a provided inside the output shaft 1 e, so that the door frame side fixing member can be rotated. The spirally coupled speed governor rod 2 on the output shaft 1 e of 1 moves up and down relative to the piston bolt 3. Therefore, the gap between the through hole formed in the piston bolt 30 and the speed governor rod 2 can be passed through the speed governor rod. The tapered part of 2 can be adjusted, and the flow path area of the gap can also be adjusted by%. In addition, a seal 33 is provided between the speed governor 2 and the buffer shaft 17 to prevent the oil in the oil chamber 27 from flowing into the hole i b. In addition, the up-and-down movement of the speed control stick 2 is not limited to the spiral method, and other methods such as manual lifting adjustment may also be used. In addition, 36 and 37 are seals and protectors for sealing the outer circumference of the cylinder 21 and the outer circumference of the piston bolt 30. 3 8 is the shaft stop wheel of the buffer shaft 1 7. The operation of the double-opening door closer with the above structure will be described below. -17- 200417671 When the door is closed, the inner wheel 10 and the outer wheel 9 are at the 0 o'clock rest position shown in Figure 7 (b).
若從該狀態向右方開啓門D、與門D固定的門側固定部 件7則向右方旋轉(參照第7圖(c))。通過該門側固定部件 7的右方向旋轉,形成在門側固定部件7上的突起1 4 一邊 壓向內輪1 0的壁部1 Oa,一邊將內輪向右旋轉。此時,爲 使內輪1 0的切口部1 Ob上保持的旋轉體1 1 a —邊止留在門 側固定部件7上形成的凹部7a中,一邊將門框側固定部件 1的一側的輸出軸1 e的外圓周移動,門框側固定部件7和 內輪1 〇形成一體地向右方移動。另一方面,在外輪9 一側 ,在門框側固定部件1的輸出軸1 e的突起1 3上接觸外輪 9的壁部9a從而阻止旋轉,同時旋轉體1 lb向形成在門框 側固定部件1的輸出軸1 e的大直徑部1 A上的凹部1 d移動 並嵌合在裏面,因此門側固定部件7能夠以其在旋轉體1 1 b 上的旋轉不被阻止的方式進行移動。此時,與內輪1 0 —體 固定的緩衝器軸1 7也沿著第8圖內開啓動作所示那樣向右 方旋轉並將螺旋彈簧18扭緊,同時將勢能積蓄在螺旋彈簧 1 8中。另外,因此同時,由緩衝器軸1 7的旋轉,活塞螺 栓3 0也向右方旋轉。由於該活塞螺栓3 0的旋轉,從而使 活塞螺栓3 0的外圓周與圓筒2 1的內表面螺旋結合,因此 僅僅活塞螺栓30由螺旋作用而向上方移動。 由於活塞螺栓3 0向上方移動,止回閥3 1打開,將上部 室2 8的油經止回閥3 1向下部室2 9移動,從而在門d開啓 動作時不發揮制動作用。但是,由於門D —邊將勢能積蓄 •18- 200417671 在螺旋彈簧1 8中,一邊被打開’因此若從門D打開狀態釋 放,由於蓄有勢能的螺旋彈簧1 8的作用使門D向關閉方向 旋轉。此時,如第8圖的開閉動作所示那樣,緩衝器軸1 7 朝著與上述相反的方向旋轉,在活塞螺栓3 0向下方移動的 同時止回閥關閉,由此從下部室29出來的油只能流過調速 棒和活塞螺栓3 0的閥座3 0 A的貫通孔之間的間隙。此時, 門側固定部件7由於是和內輪1 〇成爲一體的,因而不能被 門D的慣性所分離。因此,此時,對流過間隙的油的阻力 便能發揮對門D在關閉方向上的制動作用,門D便能慢慢 # 地關閉。另外,該關閉速度將調節調速棒2速度的調速齒 輪3 a、3 b進行旋轉,對上下移動間隙調節,因此能夠調整 門D的關閉速度。When the door D is opened to the right from this state, the door-side fixing member 7 fixed to the door D is rotated to the right (see FIG. 7 (c)). When the door-side fixing member 7 is rotated in the right direction, the protrusions 14 formed on the door-side fixing member 7 are rotated toward the right while pressing the wall portion 10a of the inner wheel 10. At this time, in order to keep the rotating body 1 1 a held on the cutout portion 1 Ob of the inner wheel 10-while remaining in the recessed portion 7 a formed on the door-side fixing member 7, The outer circumference of the output shaft 1 e moves, and the door frame-side fixing member 7 and the inner wheel 10 move integrally to the right. On the other hand, on the outer wheel 9 side, the protrusion 13 of the output shaft 1 e of the door frame side fixing member 1 contacts the wall portion 9 a of the outer wheel 9 to prevent rotation, and at the same time, the rotating body 1 lb is formed toward the door frame side fixing member 1. The recessed portion 1 d on the large-diameter portion 1 A of the output shaft 1 e is moved and fitted therein, so the door-side fixing member 7 can move in such a manner that its rotation on the rotating body 1 1 b is not prevented. At this time, the bumper shaft 17 that is fixed to the inner wheel 10 is also rotated to the right as shown in the opening action in FIG. 8 and the coil spring 18 is tightened, and the potential energy is stored in the coil spring 1 8 in. In addition, at the same time, the rotation of the bumper shaft 17 causes the piston bolt 30 to rotate to the right. Due to the rotation of the piston bolt 30, the outer circumference of the piston bolt 30 and the inner surface of the cylinder 21 are screwed together, so only the piston bolt 30 moves upward by the action of the screw. Since the piston bolt 30 is moved upward, the check valve 31 is opened, and the oil in the upper chamber 28 is moved through the check valve 31 to the lower chamber 29, so that the brake does not function when the door d is opened. However, since the door D — potential energy is accumulated • 18- 200417671 is opened in the coil spring 18 ', so if it is released from the open state of the door D, the door D is closed due to the role of the coil spring 18 that stores potential energy Direction rotation. At this time, as shown in the opening and closing action in FIG. 8, the bumper shaft 17 is rotated in the opposite direction to the above, and the check valve is closed while the piston bolt 30 is moved downward, thereby coming out of the lower chamber 29. The oil can only flow through the gap between the governor rod and the through hole of the valve seat 30 A of the piston bolt 30. At this time, since the door-side fixing member 7 is integrated with the inner wheel 10, it cannot be separated by the inertia of the door D. Therefore, at this time, the resistance to the oil flowing through the gap can exert a braking effect on the closing direction of the door D, and the door D can be slowly closed. In addition, this closing speed rotates the speed-adjusting gear wheels 3a, 3b that adjust the speed of the speed-adjusting rod 2 to adjust the vertical movement gap, so that the closing speed of the door D can be adjusted.
此外,門D從關閉狀態時開始向左方開啓時,門D和固 定在門D上的門側固定部件7 —起也向左方向旋轉(參照第 7圖(a))。由於該門側固定部件7的向左方的旋轉,形成在 門側固定部件7 —側的突起1 4 一邊壓向外輪9的壁部9a ,一邊將外輪9朝左方旋轉。此時,外輪9的切口部9b上 保持的旋轉體1 1 b被止留在門側固定部件7上所形成的凹 部7 a中,同時移動門框側固定部件1的輸出軸1 e的外圓 周,爲此門側固定部件7同外輪9形成爲一體並向左方移 動。另一方面,在內輪1 0 —側,在門框側固定部件1的輸 出軸le的突起13上接觸內輪1〇的壁部l〇a,從而阻止旋 轉,同時旋轉體1 1 a移動到門框側固定部件1的輸出軸1 e 的大直徑部1A上形成的凹部Id上並嵌合在那裏’從而能 -19- 200417671 使門側固定部件7在旋轉體1 1 a中的旋轉不能被阻止地進 行移動。此時,與外輪9固定爲一體的筒體15也如第9圖 的開啓動作所示那樣向左方移動,從而將螺旋彈簧1 8擰緊 ’同時將勢能積蓄在螺旋彈簧1 8中。與此同時,與筒體1 5 爲一體的圓筒21也向左旋轉,因而圓筒21的內周面上螺 旋結合的活塞螺栓3 0由於處在非旋轉的狀態,因此僅使活 塞螺栓30在螺旋的作用下向上方移動。 由於活塞螺栓3 0向上方的移動,止回閥3 1打開,上部 室2 8中的油經過止回閥3 1向下部室2 9移動,因此在門D 的開啓動作時不發揮制動作用。但是,由於門D —邊將勢 能積蓄在螺旋彈簧1 8中,一邊打開,若此時從門D打開狀 態釋放的話,由於積蓄有勢能的螺旋彈簧1 8的作用,門D 便向關閉方向旋轉。此時,如第9圖的開閉動作所示,外 輪9朝與前述方向柑反的方向旋轉,筒體〗5也朝相反方向 旋轉且活塞螺栓30向下方移動的同時止回閥31關閉,因 而從下部室29出來的油僅能通過調速棒2和活塞螺栓30 的閥座3 0 A的貫通孔之間的間隙進行移動。此時,門側固 定部件7由於與外輪9成爲一體,因而不能被門的慣性所 分離。從而’此時流過間隙的油的阻力能發揮對門D在關 閉方向上的制動作用,從而使門D慢慢的關閉。此外,該 關閉速度由於能對調節調速棒2的速度的調速齒輪3 a、3 b 旋轉’且對上下運動間隙調整,因而門D的關閉速度也能 被調整。 如上所示’上述實施例,無論是關於一側還是另一側的 -20- 200417671 動作’當門開啓時,都在彈性體內積蓄勢能,在門關閉時 ’利用彈性體內積蓄的勢能被來關閉門,而且,利用流向 上部室和下部室的油的移動阻力將制動作用施加於門上, 從而能使門慢慢關閉。另外,在上述詳述的實施例中,筒 體和緩衝器軸之間配置的螺旋彈簧,只要是能達到同樣功 能的彈性體的話,就能採用其他的不同形態。 以下參照附圖來說明在上述雙開式關門器中組合有自由 停止結構的雙開式關門器。本實施例的特徵爲,上述雙開 式關門器的上部中組合有自由停止結構。因此,由於關門 器的基本結構和上述實施例相同,此處主要對自由停止結In addition, when the door D is opened to the left from the closed state, the door D and the door-side fixing member 7 fixed to the door D also rotate in the left direction (see FIG. 7 (a)). Due to the leftward rotation of the door-side fixing member 7, the protrusions 14 formed on the side of the door-side fixing member 7 press the wall portion 9a of the outer wheel 9 while rotating the outer wheel 9 to the left. At this time, the rotating body 1 1 b held on the cutout portion 9 b of the outer wheel 9 is retained in the recessed portion 7 a formed on the door-side fixing member 7, and the outer periphery of the output shaft 1 e of the door-frame-side fixing member 1 is simultaneously moved. To this end, the door-side fixing member 7 is integrated with the outer wheel 9 and moves to the left. On the other hand, the protrusion 13 of the output shaft le of the door frame-side fixing member 1 contacts the wall portion 10a of the inner wheel 10 on the side of the inner wheel 10-side, thereby preventing rotation, and at the same time the rotating body 1 1 a moves to The recess Id formed on the large-diameter portion 1A of the output shaft 1 e of the door frame-side fixing member 1 is fitted there and fitted there so that the rotation of the door-side fixing member 7 in the rotating body 1 1 a cannot be changed. Stop moving. At this time, the cylindrical body 15 which is fixed integrally with the outer wheel 9 is also moved to the left as shown in the opening action in FIG. 9, thereby tightening the coil spring 18 ′ and accumulating potential energy in the coil spring 18. At the same time, the cylinder 21 integrated with the cylinder 15 also rotates to the left, so the piston bolt 30 screwed together on the inner peripheral surface of the cylinder 21 is in a non-rotating state, so only the piston bolt 30 Move upwards under the action of a spiral. Since the piston bolt 30 moves upward, the check valve 31 opens, and the oil in the upper chamber 28 moves through the check valve 31 to the lower chamber 29. Therefore, the braking effect is not exerted when the door D is opened. However, since the door D is opened while the potential energy is accumulated in the coil spring 18, if it is released from the open state of the door D at this time, the door D rotates in the closing direction due to the effect of the coil spring 18 that has accumulated potential energy. . At this time, as shown in the opening and closing action of FIG. 9, the outer wheel 9 rotates in a direction opposite to the direction described above, and the cylinder 5 also rotates in the opposite direction and the piston bolt 30 moves downward while the check valve 31 is closed, so The oil coming out of the lower chamber 29 can be moved only through the gap between the governor rod 2 and the through hole of the valve seat 30 A of the piston bolt 30. At this time, since the door-side fixing member 7 is integrated with the outer wheel 9, it cannot be separated by the inertia of the door. Therefore, at this time, the resistance of the oil flowing through the gap can exert a braking effect on the door D in the closing direction, thereby slowly closing the door D. In addition, the closing speed can be adjusted by adjusting the speed adjustment gears 3a, 3b for adjusting the speed of the speed control stick 2, and the vertical movement gap, so the closing speed of the door D can also be adjusted. As shown above, 'the above-mentioned embodiment, whether it is about -20-200417671 action on one side or the other side', when the door is opened, potential energy is accumulated in the elastic body, and when the door is closed, the potential energy accumulated in the elastic body is used The door is closed, and the braking force is applied to the door by the movement resistance of the oil flowing to the upper and lower chambers, so that the door can be closed slowly. In addition, in the embodiment described in detail above, as long as the coil spring disposed between the cylinder and the bumper shaft is an elastic body capable of achieving the same function, other different forms can be adopted. Hereinafter, a double-opening door closer in which the free-stop structure is combined in the double-opening door closer will be described with reference to the drawings. This embodiment is characterized in that a free-stop structure is combined in the upper part of the double-opening door closer.

However, other materials with the same function can be used. As shown in FIG. 11, a roller groove (combination portion) 62 for connecting a rotating member (hereinafter referred to as a roller) 6 1 is formed on an outer circumferential surface of a lower portion of the output shaft 60 fixed by the door frame-side fixing member 1. The roller grooves 62 are formed at two positions separated by 180 degrees (refer to FIG. 13 described later).
經襯套67可旋轉地嵌合在該輸出軸60中的滾柱保持器 63採取如第1 1圖和第12圖所示的由大直徑部63a和小直 徑部6 3 b形成的斷面爲倒帽形的結構。The roller holder 63 rotatably fitted in the output shaft 60 via the bushing 67 takes a section formed by a large-diameter portion 63 a and a small-diameter portion 6 3 b as shown in FIGS. 11 and 12. It is an inverted hat-shaped structure.
滾柱保持器63上形成有中心部被***調速棒2的貫通孔 64,另外如第11圖和第12圖所示那樣,在大直徑部63a 的上半部分中保持上述滾柱6 1的、側視爲U形的貫通溝 6 3 c形成在兩相隔1 8 0度的位置上,另外在大直徑部6 3 a 的下半部分中形成有嵌合並被保持在內輪1 〇和外輪9中所 形成的切口部l〇b和9b中的旋轉體1 1的圓弧狀凹部63d 。該凹部6 3 d對應於形成在上述實施例的輸出軸1 e中的凹 部Id 〇 在輸出軸60和滾柱保持器63以及內輪1 〇和外輪9的外 圓周上,如第1 0圖所示那樣,配置有門側固定部件7。另 外,如第1 1圖和第13圖(第1 1圖中C-C剖視圖)所示那樣 ,上述門側固定部件7的內圓周面中相對於〇點靜止位置 ,上述輸出軸的下部外圓周面上形成的滾柱溝62被相隔1 8 0 度地形成在兩個位置上,還形成有作爲具有相對於滾柱6 1 約兩倍的直徑的結合部的溝6 5。該溝6 5的大小根據門開 -22· 200417671 閉角度的大小也可以爲大約滾柱6 1的直徑。另外,上述溝 65並非一定要在兩處形成,61若爲一個,則也可在一處形 成,另外溝6 5的形狀也可以採取在嵌合滾柱6 1的上述實 施例中說明的圓弧形凹部。The roller holder 63 is formed with a through hole 64 into which the speed governing rod 2 is inserted at the center, and the roller 6 is held in the upper half of the large-diameter portion 63a as shown in FIGS. 11 and 12. The U-shaped through grooves 6 3 c are formed at two 180-degree intervals, and a fitting is formed in the lower half of the large-diameter portion 6 3 a and held by the inner wheel 1 0 and The arc-shaped recessed portion 63d of the rotating body 11 in the cutout portions 10b and 9b formed in the outer wheel 9. The recessed portion 6 3 d corresponds to the recessed portion Id formed in the output shaft 1 e of the above-mentioned embodiment on the outer circumference of the output shaft 60 and the roller holder 63 and the inner wheel 10 and the outer wheel 9 as shown in FIG. 10. As shown, the door-side fixing member 7 is arranged. In addition, as shown in FIG. 11 and FIG. 13 (CC cross-sectional view in FIG. 11), among the inner peripheral surfaces of the door-side fixing member 7, the outer peripheral surface of the lower portion of the output shaft with respect to the 0-point rest position, The roller grooves 62 formed above are formed at two positions at 180 degrees apart, and grooves 65 are formed as joint portions having a diameter approximately twice that of the rollers 6 1. The size of the groove 65 may be approximately the diameter of the roller 61 according to the opening angle of the door -22 · 200417671. In addition, the groove 65 is not necessarily formed at two places, and if one is 61, it may be formed at one place. In addition, the shape of the groove 65 may be a circle described in the above embodiment of the fitting roller 61. Curved recess.
另外,在對應於內輪1 0和外輪9的滾柱保持器6 3形成 有與上述實施例的輸出軸le的大直徑部1A上形成的圓弧 形凹部1 d相當的圓弧形凸部63d,同時還形成有與形成在 輸出軸1 e上的突起1 3相對應的突起6 6。這樣,滾柱保持 器6 3、內輪1 0、外輪9、以及門側固定部件7如第1 4圖 所示那樣形成與上述實施例相同的組合結構。另外,滾柱 保持器63、內輪1 0、外輪9、門側固定部件7的動作也與 上述的實施例相同,在此省略對它們的詳細說明。 現在參考第1 5圖來說明上述自由停止結構的作用。In addition, the roller retainer 63 corresponding to the inner wheel 10 and the outer wheel 9 is formed with an arc-shaped convex portion corresponding to the arc-shaped concave portion 1 d formed on the large-diameter portion 1A of the output shaft le of the above embodiment. 63d, at the same time, protrusions 6 6 corresponding to the protrusions 13 formed on the output shaft 1 e are also formed. In this way, the roller retainer 6 3, the inner wheel 10, the outer wheel 9, and the door-side fixing member 7 have the same combined structure as that of the above-mentioned embodiment as shown in Fig. 14. The operations of the roller holder 63, the inner wheel 10, the outer wheel 9, and the door-side fixing member 7 are the same as those of the above-mentioned embodiment, and detailed descriptions thereof will be omitted here. The effect of the above free stop structure will now be described with reference to FIG. 15.
在第1 5圖(b)中,門處於關閉狀態時,內輪1 0、外輪9 、滾柱保持器63位於0點靜止位置(對應於上述實施例的 第7圖(b)),滾柱保持器63和輸出軸60以及門側固定部件 7同樣也位於0點靜止位置。 從該狀態起如第1 5圖(〇所示,門D向右方向開啓時, 與門D相固定的門側固定部件7向右方旋轉,由於該門側 固定部件7的右方向的旋轉,如上述實施例中所述的那樣 ,門D在螺旋彈簧1 8中積蓄勢能的同時被打開,因此若從 門打開的狀態釋放的話,在積蓄有勢能的螺旋彈簧1 8的作 用下門D向關門的方向旋轉。此時,由於制動作用,門D 便慢慢地關閉。 -23- 200417671 另外,在自由停止機構中,首先,在門D關閉的〇點靜 止位置,保持在滾柱保持器6 3上的滾柱6 1結合在輸出軸 60上所形成的滾柱溝62中。由此,如甩手推開門D的話 ,在自由停止機構一側,與門D成一體旋轉的門側固定部 件7向相同方向轉動。此時,滾柱保持器6 3通過滾柱6 1 與輸出軸6 0形成一體,處於非旋轉狀態。這樣,內輪1 0 或外輪9中所結合的螺旋彈簧1 8中與上述實施例一樣地被 積蓄彈性力。接下來將門D於途中放開的話,門D便通過 螺旋彈簧1 8的彈性力返回原處。 _ 但是,若將門D打開90度(參照第15圖(〇),此時,滾 柱保持器63中所保持的滾柱6 1從輸出軸60 —側所形成的 滾柱溝62向形成在門側固定部件7的內圓周面上的尺寸大 的溝65內移動,滾柱61向輸出軸60的外圓周面移動,通 過輸出軸60和滾柱保持器63的滾柱6 1的結合便被解除, 接著滾柱保持器63和門側固定部件7通過滾柱6 1形成一 體。其結果,在螺旋彈簧1 8中積蓄的彈性力被維持的情況 下,門D —側固定部件7在滾柱61被收容在溝65內的狀 I 態下能夠在輸出軸60的外圓周上自由旋轉,此外若停止門 側固定部件7的旋轉的話,門D能在該位置上維持停止狀 態。這樣在本例中,即使超過9 0度進一步打開門D的話,In FIG. 15 (b), when the door is closed, the inner wheel 10, the outer wheel 9, and the roller holder 63 are located at the 0-point rest position (corresponding to FIG. 7 (b) of the above embodiment). The column holder 63, the output shaft 60, and the door-side fixing member 7 are also located at the 0-point rest position. From this state, as shown in FIG. 15 (0), when the door D is opened to the right, the door-side fixing member 7 fixed to the door D rotates to the right, due to the right-side rotation of the door-side fixing member 7. As described in the above embodiment, the door D is opened while the potential energy is accumulated in the coil spring 18, so if it is released from the state in which the door is opened, it is under the action of the coil spring 18 that has accumulated potential energy. The door D rotates in the direction of closing the door. At this time, due to the braking effect, the door D is slowly closed. -23- 200417671 In addition, in the free stop mechanism, first, at the 0-point stationary position where the door D is closed, it is maintained in the roll position. The roller 61 on the column holder 63 is combined with the roller groove 62 formed on the output shaft 60. As a result, if the door D is opened by a shake, the door D rotates on the side of the free stop mechanism. The door-side fixing member 7 rotates in the same direction. At this time, the roller holder 63 is integrated with the output shaft 60 by the roller 6 1 and is in a non-rotating state. In this way, the inner wheel 10 or the outer wheel 9 is combined An elastic force is accumulated in the coil spring 18 similarly to the above-mentioned embodiment. If you lower the door D and release it on the way, the door D will return to its original position by the elastic force of the coil spring 18. _ However, if you open the door D 90 degrees (refer to Figure 15 (〇), at this time, the roller holder 63 The roller 61 held in the middle moves from the roller groove 62 formed on the side of the output shaft 60 to a large-sized groove 65 formed on the inner peripheral surface of the door-side fixing member 7, and the roller 61 moves toward the output shaft 60. The outer peripheral surface of the roller is released by the combination of the output shaft 60 and the roller 61 of the roller holder 63, and then the roller holder 63 and the door-side fixing member 7 are integrated by the roller 61. As a result, When the elastic force accumulated in the coil spring 18 is maintained, the door D-side fixing member 7 can rotate freely on the outer circumference of the output shaft 60 in a state where the roller 61 is accommodated in the groove 65. In addition, if the rotation of the door-side fixing member 7 is stopped, the door D can maintain the stopped state at this position. In this example, even if the door D is opened further than 90 degrees,
在此之後在所希望的位置上都能將門D停止在任意的位置 。另外,在關閉門D時,在9 0度以內若門D返回時,在 螺旋彈簧1 8的彈性力的作用下,門D能自動地關閉。此時 ’上述實施例中說明的制動作用起作用,從而能回避門D -24- 200417671 的急劇關閉的作用。另外,在反向一側開門時,若門D打 開90度’如第15圖(a)所示那樣也能得到與第15圖(b)相 同的同彳永動作的自由停止狀態。 如此’在本實施例中,門側固定部件7的內圓周面上形 成的溝6 5以〇點爲中心具有向左向右以相同長度(約爲滾 柱6 1的直徑)分開的寬度,因此門d從0點靜止位置開始 左右90度開啓時的那一點開始便能得到自由停止的狀態。 但是’在單側90度打開的狀態,爲能得到自由停止狀態 ’如第1 6圖(b)那樣在門側固定部件7的內圓周面上形成 的溝7 1以0點爲中心在偏開α度的位置上,滾柱61嵌合 在圓弧形凹部的場合,如第1 6圖(c)那樣,將門D向右側 開啓時’門D從90度開啓時的那一點開始便能得到自由停 止的狀態。但是,門D在相反一側開啓的場合,如第j 6 圖(a)所示那樣,若不開到(90 + 2〇〇度的話,就不能得到自由 停止的狀態。這樣,門側固定部件7的內圓周面上所形成 的溝7 1在以0點爲中心偏開α度的位置上形成的場合(例 如上述已有技術,參照特開平1 0 - 2 2 0 1 〇 2號公報),根據左 右開啓的角度得到自由停止狀態的開度是不一樣的,便會 產生與雙開式關門器等的場合不相配的情況。然而,即使 是雙開式關門器,在建築物的結構和雙開的角度不一樣的 場合’也能採用如第1 6圖所示那樣的自由停止結構。 採用以上所示的上述實施例,可構成在雙開式關門器中 附加滾柱保持器和滾柱的自由停止結構,由於這種構成方 式簡易,因此適合於小型化。 -25- 200417671 另外,上述實施例僅僅爲示例性的,在不脫離本發明的 精神和主要特徵的情況下,本發明仍然可以實施爲其他不 同的形式,而不應對此加於限定性的解釋。After that, the door D can be stopped at an arbitrary position at a desired position. In addition, when the door D is closed, the door D can be automatically closed by the elastic force of the coil spring 18 when the door D returns within 90 degrees. At this time, the braking action described in the above embodiment works, so that the action of the sudden closing of the door D-24-200417671 can be avoided. In addition, when the door is opened at the opposite side, if the door D is opened 90 degrees' as shown in Fig. 15 (a), a free stop state of the same permanent operation as in Fig. 15 (b) can be obtained. In this way, in the present embodiment, the grooves 65 formed on the inner circumferential surface of the door-side fixing member 7 have a width separated from the left to the right by the same length (approximately the diameter of the roller 61) around the 0 point. Therefore, the door d can be in a free stop state from the point when the door d is opened at 90 degrees from the left and right. However, the groove 71 formed on the inner circumferential surface of the door-side fixing member 7 as shown in Fig. 16 (b) is freely stopped in a state where it is opened at 90 degrees on one side. When the roller 61 is fitted into the arc-shaped recess at the α-degree position, as shown in Figure 16 (c), when the door D is opened to the right, the door D can be opened from the point when it is opened at 90 degrees. Get free stop. However, when door D is opened on the opposite side, as shown in Figure 6 (a), if it is not opened to (90 + 200 degrees), the free stop state cannot be obtained. In this way, the door side is fixed When the groove 7 1 formed on the inner circumferential surface of the member 7 is formed at a position that is shifted by α degrees from the center of 0 point (for example, in the above-mentioned conventional technology, refer to Japanese Patent Application Laid-Open No. 10-2 2 0 1 〇2 ), According to the opening angle of left and right to get the free stop state is not the same, it will not be suitable for occasions such as double-opening door closers. However, even double-opening door closers, in the structure of the building and When the double-opening angle is different, a free-stop structure as shown in Fig. 16 can also be adopted. With the above-mentioned embodiment, a roller holder and rollers can be added to the double-opening door closer. The free-stop structure is suitable for miniaturization due to its simple structure. -25- 200417671 In addition, the above embodiments are merely exemplary, and the present invention can still be used without departing from the spirit and main features of the present invention. Other embodiments of different forms and should not be applied to this interpretation limiting.
如以上詳細說明的那樣,本發明具有如下優異的效果, 由於彈簧式關門器內安裝有油壓制動結構,對裝置能夠小 型化的同時也簡化了其結構,其結果,能在門內容納雙開 式關門器,且使施工變得容易,另外也不受雨和清掃時的 淸潔劑的影響。因爲能夠從左右任何一側打開,因而擴大 了使用範圍,另外,本發明由於安裝有自由停止結構,因 此門開啓的角度可從左右超過9 0度的位置開始連續地發 揮停止的功能,並且由於溝寬度形成得大,因此在左右任 何方向90度的位置上都能發揮自由停止的功能。 (五)圖式簡單說明 第1圖爲有關本實施例的雙開式關門器,安裝在門上的 狀態的正視圖和側視圖;As explained in detail above, the present invention has the following excellent effects.
