Specifically, the liquid damper in 丨哥刊2 is used in the door closer and is designed as Ding. a rice sigh is as follows: when the door is opened, the resistance becomes small and can be easily opened, and when the door is closed Increase the resistance to avoid violent closure, thereby slowly closing the door; at the end of the closure, reduce the resistance to be able to close properly. Further, the improvement of the present invention is disclosed in the following Patent Document 3 by the applicant of the present application. [Patent Document 1] Japanese Laid-Open Patent Publication No. 2003-193740 (Patent Document 3) JP-A-2003-193740 (Patent Document 3) Problem j However, 'fluid damper" 5 Γ 4 · u ^ According to its purpose, various resistance change actions are performed by various configurations.

The fluid damper that exhibits such a function has the structure of the above-described Patent Document 3. However, it is desirable to complete a fluid damper that is a structure that replaces the above-described structure, or to achieve a more soft storage feeling than the structure of Patent Document 3. A fluid damper constructed. The problem to be solved by the present invention is to provide a fluid damper that can gently withstand an imminent load by a configuration different from the prior. [Technical means for solving the problem] The first invention provides a fluid damper characterized in that, in a chamber filled with a fluid, an operating shaft moves back and forth along a longitudinal direction of the sleeve, and an inner diameter of the sleeve The size is constant within the operating range of the operating axis along the longitudinal direction, and a fixed position member is disposed at a predetermined position of the operating shaft, and the fixed position member divides the chamber of the sleeve into two front and rear portions, and has a a fixed position member communication path connecting the two chambers, and a small flow path smaller than the communication path of the fixed position member is disposed between the outer periphery of the fixed position member and the inner surface of the sleeve, and has a moving member (24) The member (24) is disposed to face the fixed position member, and is movable back and forth on the actuating shaft between the fixed position member and the position of the movable member to face the fixed position member. In the opposite side region, and the right suspension + | ^ / Ή large towel w degree protrudes from the fixed position member side (24 Τ), the convex portion is elastic and compressible in the front and rear direction And the restored elastic member, the convex portion does not block the communication of the two chambers obtained by the communication path of the fixed position member even if it abuts against the fixed position member; and has a side facing region facing the fixed position member Lower than the lower portion (24L) of the convex portion 6 1344521, the lower portion can abut against the fixed position member by the contraction of the convex portion, and can block the transmission when abutting the fixed position member The communication between the two chambers of the fixed position member communication path is provided with an elastic block in the chamber of the sleeve. The elastic block can be contracted and restored by the pressure of the fluid. The sleeve of the present application is not limited to a cylinder, and may have a rectangular cross section. The positional member and the moving member are not limited to a circular shape, and include a rectangular shape or the like. , n i 参 i 山 - λ 冋 冋 , , λ λ λ λ λ λ λ λ λ λ λ λ λ λ λ λ λ λ λ λ 。 。 。 。 。 。 。 。 &, f must not require rigor in the sense of number, but rather roughly. However, it does not include a large change in the diameter of the gap 3 (Fig. 7 described below) which is a significant factor for the loss of the fluid resistance of the small flow path. Specifically, in the case of using a mold to form a sleeve, the direction of the mold release is slightly tapered in order to perform the stripping, but the degree is determined as described in the application; * As an elastic block, there is a foaming amine bismuth citrate. In order to prevent fluid from entering the inner portion of the inner portion of the elastic block, the holes are not communicated with each other so as to open almost to the surface of the elastic block. The second invention has a configuration in which a history of the front side or the rear side of the first invention is applied to the spring force of the first invention. The third aspect of the invention is as follows: the moving member of the first invention is tied

The fourth invention is configured such that the moving member fixing convex portion which is further invented than the fixed position member is formed close to the elastic member which is soft to the operation, and the lower side of the four-axis direction is the lower side. The portion is located on the outer side in the radial direction from the convex portion. The moving member formed as in the fifth invention is provided in the clamp; the position of the elastic member is fixed by the receiving member between the upper member, the ten-turn & magnetic & The receiving member is formed by a radial direction of the member which is harder than the moving member, and has the same function as the moving member. [Invention] In the invention, when the external force acts through the operating shaft, the error occurs. By pushing the moving member against the member with the external force, but the pressure rise does not cause the convex portion of the most protruding moving member to be largely collapsed, and the lower portion and the fixed position member of the moving member are still Isolated. Therefore, the two chambers can be connected via the fixed position member communication path, and therefore, the resistance of the fluid damper is small. On the other hand, when the external force is activated by the actuating shaft, the fluid rising pressure corresponding to the external force pushes the moving member to the solid-state position member, and the convex portion thereof is largely collapsed and moved. The lower portion of the member is also urged to the fixed position member. Therefore, the communication cannot be performed via the fixed position member communication path, and the indoor fluid on the side where the pressure rises rapidly flows into the other chamber only through the small flow path, and therefore the resistance of the fluid damper is large. That is, it can withstand the rush of force. However, *, not only that, the volume of the elastic block changes due to the above-mentioned rising pressure. Therefore, the force of the above-mentioned emergency 1344521 can be alleviated, and the external force can be received with a soft feeling. In addition, the movement of the actuating shaft causes the volume of the moving shaft to enter and exit. The volume of the fluid in the casing must be varied by the above-mentioned volume fluctuation. Especially when the fluid is a liquid, the liquid itself is difficult to absorb the volume change. The elastic block absorbs this volume change. According to the second aspect of the invention, if the biasing means is provided, the operating shaft can be pushed back to the original position. Therefore, the fluid damper can be automatically reused.

According to the fifth aspect of the invention, the actuating shaft can be pushed back to the original position by the biasing means, but when the (4) divergence is pushed back, the moving member formed by the (four) member is pushed by the pressure of the fluid toward the direction away from the fixed position member. However, since there is a deformation structure which is harder than the moving member and has a radial direction size equal to or larger than the moving member, the moving member is supported, so that the moving member can maintain its shape and durability when it is repeatedly used. improve. [Embodiment] Fig. 1 is a side view of a furniture in which a liquid damper 4 of the present invention is mounted, similar to a piston type cylinder mechanism, and Fig. 2 is a damper of a furniture from 2 observations. Fig. 3 is a diagram showing the longitudinal action of the external structure of the external structure when the liquid damper used in Fig. 1 is externally applied, and the system, state and Fig. 3 are not: Fig. 5 shows the state of the change from the state of Fig. 4, Fig. 6 is the diagram of the state change from Fig. 5, Fig. 7 is the enlarged view of the main part of Fig. 3, and the enlarged view of the main part of Fig. 8 ... 9 is an enlarged view of the main part of Figure 5. 9 1344521 The furniture 50 of Fig. 1 is, for example, a storage cabinet for a kitchen. The liquid damper 40 to be described below is provided on the back side of the top plate 5A, in order to receive and hold the bracket 48. The damper 40 is 贱, and the liquid damper 4 〇 has the following functions: when passing through the hinge When closing the single-open or double-opening door 5〇c, the closing momentum is absorbed to close quietly. The structure of the helium liquid damper corresponds to a cylinder. In this example, the inner diameter of the casing of the inner wall surface 1A of the cylindrical sleeve s 10 is defined as the operating range of the lug axis 12, regardless of The position in the long side direction is fixed. The actuating shaft 12 can advance and retreat as follows, that is, from the right side of the sleeve in Fig. 3 to the left direction, and retreat from the left to the right direction by the coil spring 2Q as the biasing means. An oil as an actuating fluid is sealed in the sleeve s 10, and the member is tightly sealed to prevent the oil leakage member 29 from being actuated by the actuating shaft 12. A rubber member 安装 is attached to the outer end portion of the operating shaft as a direct/receptive portion from the external impact force. Further, a fixed-position member 22 having a body shape is formed at the inner side end portion, and the outer periphery of the fixed-position member 22 is close to the inner wall surface 1A of the sleeve 10, and is moved together with the operating shaft; the tilting shaft 12 is moved. On the opposite side, a central station Αβ ! 〇, . , (the focal point of the central axis 12, which is also described in the present application) One part of the actuating shaft. One: fixed position (four) pieces divide the chamber of the casing into two parts of the left chamber A and the right chamber B, and the positional member communication path 22H, which has the force position of the fixed position member 22H The cross-sectional area of the member 吏 from left to right and 10 is placed in the central shaft portion 12, and the receiving member 26β I shown at the (left) front end portion 10 has, for example, the drawing member 22 and the bearing member 26 The fixed position is provided with (four) moving member 24, and the moving member 24 is formed by T, that is, softened by compressibility and recovery: the member has a larger outer diameter than the moving member 24: the receiving member also receives the coil spring 2〇 One end. The hair: 2 左 left end, equipped with a cylindrical box = 14 = packet-carboxylic acid ethyl vinegar of porous resilient block 16, which is contracted by the ^ :) oil recovery. A gas is enclosed in each of the porous holes (the air force is such that the inner oil can not be immersed into the inner portion of the elastic block, thereby causing the outer hole to collapse) while softly compressing and restoring the porous portion of one portion::: : they are not connected to each other but exist independently, and therefore, the gas 4 can be prevented from leaking, and the oil can be prevented from immersing into the inside of the hole. The moving member 24 is located near the center side of the radial direction of the operating shaft and is surrounded by the operating shaft. The central axis portion of the shaft of the shaft is provided with a convex portion: and a 'outer region of the annular groove 24κ that is spaced apart from the outer side of the convex portion 24T; and a lower portion of 4 24L 'the lower portion 24L is higher than the above-mentioned annular groove, but lower than the above-mentioned convex portion. In addition to the form of this example, the moving member may be a base material such as a hard shell member such as a metal plate, for example, a disk-shaped base material. The elastic member is disposed on the front side of the circular plate, and the convex portion and the lower portion are disposed as described above. When the shape is clear, the moving member may be omitted by the base material. To bear the receiving member 26 of the moving member, that is, the bearing shown in FIG. 3 and the like The member 26 may be provided as a member having only a function of receiving one end portion of the coil spring 20.

Therefore, in the initial stage of the example, the moving member is placed in the initial direction of the rubber member of the outer side end of the actuating shaft when the external force in the direction in which the manipulating shaft is pushed in the sleeve is as shown in FIG. The convex portion 24 of the squeegee moving member 24 that receives the oil in the left chamber A from the left side is pressed against the end surface of the fixed position member 22 and collapses, and the county, the 'last' self-receiving member 26 and The moving member 24 = the gap as a whole is subjected to the rising pressure and is further collapsed. Thus, the lower portion 24L of the low cow peripheral ridge is also pushed to the end face of the position member outside the fixed position member communication path 22'. Bamboo Department: This oil does not flow through the solid-state position member communication path 22H of the fixing member 22 due to the pressure difference between the left ventricular iliac crest and the right ventricular iliac crest, but only the outer peripheral surface of the fixed position member 22 and the casing are azole. The small flow path 2 formed by the gap 5 between the inner surfaces ι is flowing. Therefore, the left ventricle can be subjected to a strong external force. The inner chamber of the casing is about 1 〇 min.
If形時’上述較小之間隙5例如小至5〇 12 1344521 # m左右。 於該情形時，上述彈性塊16藉由上述上升壓力而使多 孔潰縮，同時以柔軟之感覺進行壓縮變形。因此，亦可柔 軟地承受較強之急遽之外力。 在該彈性塊16之壓縮變形、及經由上述小流路22SH 之流動該兩者之作用下，左室A内之壓力逐步降低。因此， 移動構件24之凸部24T之較大之壓縮變形稍微恢復，並成 為圖5及圖9所示之狀態。亦即，低部24L解除與固定位 置構件22之端面抵接之狀態。因此，低部與固定位置構件 端面之間產生流路，油可經由固定位置構件連通路徑 而λιι·動因此，可快速地減小左室Α與右室Β之壓力差， 從而對於作動軸12之進入不存在較大之阻力。 於該情形時，位於左室A中之盤簧2〇受到壓縮而欲恢 復之彈力雖會將作動軸12朝原來之狀態之外（右方向）擠 壓’但可藉由未圖示之彈簧來抵消該力，該彈簧之作用在 於將設置於圖i之傢具5〇之櫃門5〇c之鉸鏈的櫃門關閉。 實際上，作動軸12可進入最後之末端位置係由於該鉸鏈之 彈簧力之作用。 如此，最後凸部24T之壓縮變形伸展為原來之狀態， 成為處於作動軸行程之末端位置之圖6之狀態。維持該圖6 之狀態之力係上述鉸鏈之彈簧力。若利用與該鉸鏈彈簧力 反向之人力來打開櫃門5〇c，則會於盤簧2〇之作用下，自 動地將作動轴12推回至圖3之狀態。於將該作動轴Η推 回之過程中，右室B之油經由固定位置構件22之固定位置 13 1344521 牛連通路授22H而流向左室A，因此，不會表現出特別 大之阻力’可利用盤簧20之力來將上述作動軸12推回。 於推回該作動軸丨2時，整體由柔軟之彈性構件所形成之移 動構件24受到左侧之承受構件26擠壓而保持其圓板狀之 形狀。 再者，圖6之狀態之彈性塊16自原來之圖3之尺寸縮 小的體積，係與進入至套管内之作動軸12之體積之增加量 相同。 夕於外力較弱之情形時，左室A之油之壓力上升較小， 移動構件24之凸部24T不經由如圖4 (圖8)般之大幅度 擠壓狀態便成為圖5 (圖9)之擠壓狀態。因此，左室Α之 油會充分地流向右室B，故而流體阻尼器相對於作動軸之進 入僅表現出較小之阻力。 貝他例T之移勤構件一…町、怕処在不受外力之 通常時之狀態下，正好央持於固定位置構件22與承受構件 26之間，且前後不存在間隙之狀態，但亦可為固定位置構 件22與承受構件26之間之間隔超過移動構件24之最大厚 度之尺寸而為如下形態：於不受外力之通常時之狀離下， 在移動構件與固定位置構件之間存在間隙。 ， 與以上之例不同地，以下對將本申 尼器應用於㈣之η之例加以說明。套管發=流體阻 與圖"所示者相同之圓筒形，但此處設二 形狀之薄型之套管。因此，固^位置構件22、移 以 承欠構件26,自左右任—方所見之端面形狀均為矩形狀而If the shape is 'the smaller gap 5 is as small as 5 〇 12 1344521 # m or so. In this case, the elastic block 16 is collapsed by the above-mentioned rising pressure, and is compressed and deformed with a soft feeling. Therefore, it is also soft to withstand the strong impetuous forces. The pressure in the left chamber A is gradually lowered by the compression deformation of the elastic block 16 and the flow through the small flow path 22SH. Therefore, the large compression deformation of the convex portion 24T of the moving member 24 is slightly restored, and the state shown in Figs. 5 and 9 is obtained. That is, the lower portion 24L is released from the state in which it is in contact with the end surface of the fixed position member 22. Therefore, a flow path is formed between the lower portion and the end surface of the fixed position member, and the oil can be moved by the fixed position member communication path, so that the pressure difference between the left ventricular sac and the right sac can be quickly reduced, thereby operating the shaft 12 There is no greater resistance to entry. In this case, the coil spring 2 located in the left chamber A is compressed and the elastic force to be restored will press the actuation shaft 12 outward (the right direction) but can be rotated by a spring (not shown). To counteract this force, the spring acts to close the hinged door of the cabinet door 5〇c of the furniture 5图. In effect, the actuation of the shaft 12 into the final end position is due to the spring force of the hinge. Thus, the compression deformation of the final convex portion 24T is extended to the original state, and it is in the state of FIG. 6 at the end position of the actuation shaft stroke. The force that maintains the state of Fig. 6 is the spring force of the above hinge. When the cabinet door 5〇c is opened by the manpower opposite to the hinge spring force, the operating shaft 12 is automatically pushed back to the state of Fig. 3 by the coil spring 2〇. During the pushing back of the actuating shaft yoke, the oil of the right chamber B flows to the left chamber A via the fixed position 13 1344521 of the fixed position member 22, and therefore does not exhibit a particularly large resistance. The above-described actuating shaft 12 is pushed back by the force of the coil spring 20. When the actuating shaft 2 is pushed back, the moving member 24 formed entirely of the soft elastic member is pressed by the receiving member 26 on the left side to maintain its disk shape. Further, the volume of the elastic block 16 in the state of Fig. 6 which is reduced from the original size of Fig. 3 is the same as the volume of the movement shaft 12 which enters the sleeve. In the case where the external force is weak, the pressure of the oil of the left chamber A rises little, and the convex portion 24T of the moving member 24 does not pass through the state of being squeezed as shown in Fig. 4 (Fig. 8), and becomes the Fig. 5 (Fig. 9). The squeeze state. Therefore, the oil of the left ventricular sac will flow sufficiently to the right ventricle B, so that the fluid damper exhibits only a small resistance with respect to the movement of the actuation shaft. In the state where the external member is not subjected to external force, it is just between the fixed position member 22 and the receiving member 26, and there is no gap between the front and the rear, but also The distance between the fixed position member 22 and the receiving member 26 may exceed the maximum thickness of the moving member 24 in such a manner that it is separated from the normal state of the external force and exists between the moving member and the fixed position member. gap. Unlike the above example, the following applies to the case where the present application is applied to the η of (4). Casing hair = fluid resistance The same cylindrical shape as shown in the figure, but here is a thin sleeve of two shapes. Therefore, the position member 22 and the under-receiving member 26 are rectangular in shape from the left and right sides.

In addition to this, the position member 22 and the moving member 24 will be fixed. Second, the actuating shaft 12 is penetrated. The member 22 and the receiving member 26 are fixed to the mounting position of the actuating shaft. Since the moving members 24 have the same function, they are omitted here.

According to the description of the case of the above-mentioned storage cabinet, it can be seen that it is very easy to extract when it is taken out, and even when the storage is performed, even when the automatic pulling device starts to operate, the oil resistance is presented. The strongest resistance, along with the compression of the elastic block 16, withstands its momentum with a soft feeling. After that, the oil resistance of the original car will be rapidly reduced. Therefore, the automatic pulling force generated by the elastic force of Panhuang 2 can be used to accommodate the exhibition.

For example, the automatic pulling device uses a device having a sliding structure #34 having a recess W4A, which is sufficient to be placed in a convex shape of the drawer of the cabinet. The part η phase is engaged. The automatic pulling-in device is disposed, for example, between one of the wall faces 3A and the other wall faces 3B of the rail members 3A having the same width as the sleeve f1, and is slidably movable in the longitudinal direction. & It is possible to make the tilting of the head 12H of the actuating shaft 12 of the liquid damper rotatably engaged with the sleeve side end portion of the sliding member, with the actuating shaft being along the longitudinal direction of the sliding member Move up and move forward and backward. Engagement holes or engagement recesses 3〇H are formed at appropriate positions of the other wall surface 30B of the rail member 30. On the other hand, an engaging convex portion 34b is provided on the side of the sliding member Μ 15 1344^21 facing the wall surface 30B. Further, the point of action of the tension (4) engaged with the concave portion 34A against the tensile force of the sliding member 34 is located at a position offset from the central axis of the operating shaft U toward the wall surface 30A, as the drawing is toward the figure. The right direction (the evacuation opening direction) is moved, and the moment M in the clockwise direction in the drawing is generated on the sliding member 34. Therefore, during the movement of the sliding member in the right direction, the convex portion directly presses the wall fan, and when it reaches the engaging hole 3〇H, it enters the engaging hole and engages with it. As a result, the sliding member is inclined in a manner not shown in FIG. 34, the engagement between the convex portion 32 and the concave portion 34A is released, and the drawer is moved to the right in a state where the sliding member is left at the position of the engaging hole until the drawer is moved to the right direction. When the drawer is completely withdrawn (by the symbol ", it indicates that the sliding member is at the position shown in the above-mentioned position 34, and the position of the operating shaft 12 is fully extracted. Further, the cartridge 20 is in the most compressed state. Thereafter, in the case of the receiving and the inner drawer, the drawer is pushed in by hand, and if the convex portion 32 presses the left side wall surface of the recessed portion 34A into the end side wall 12), then the sliding member is The torque in the counterclockwise direction in the figure is generated to cancel the engagement between the engaging convex portion 34B and the engaging hole. Thereafter, even if the person does not push the scraping, the elastic force of the coil spring can be automatically used: In the final position of the drawer, the sliding member is "located at the position shown on the left side of the figure, and the actuating shaft is at the end position. Automatically pull in the hand / can also be other forms, and is not limited to the form. FIG. 1 is a diagram of the structure of the body damping state in which the fluid force of the present invention is generated, but the difference between FIG. 13 and the circle i] U44521 is used in the case of extracting the action & The point is that the moving member 24 and the receiving member 26 are disposed on the side of the right chamber B. The effect is apparent from the description of the original storage cabinet and is therefore omitted here. [Industrial Applicability] The present invention can be utilized for furniture, doors, and the like having an open cabinet door, a teak door, a drawer, and the like.
