OBJECTS OF THE INVENTION: TECHNICAL FIELD OF THE INVENTION [0001] The present invention relates to hinges for doors, particularly glass doors, more particularly, but not exclusively, frameless glass doors. [Prior Art] [0002] A frameless glass door requires a door stop to be in the closed position. An internal door stop has been disclosed in U.S. Patent No. 6,056,821. W0201 1 /020630 discloses a glass door hinge with an internal door stop device comprising: a housing; a support connecting the housing to the support member; a pair of clamps; an axial shaft; and a plurality of offsets a member arranged to engage the rotating shaft to return the clamps to one of a plurality of positions selected from a closed position and one or more open positions; wherein the rotating shaft has a plurality of centering surfaces; The biasing member is arranged to apply a force to the corresponding centering surface to center the clamp in one or more of the positions. The disclosure of this specification is hereby incorporated by reference in its entirety in its entirety in its entirety in its entirety herein in its entirety SUMMARY OF THE INVENTION [0003] According to the present invention, a door hinge with an internal door stop device includes: a housing; a holder that connects the housing to the support member; a pair of ware; an axial shaft; and a Or a plurality of biasing members arranged to engage the rotating shaft to return the clamps to one of a plurality of positions selected from the closed position and the one or more open positions; 10013736 dream list number A〇101 Page 4 of 65, 1013097133-0 201224266 wherein the shaft has one or more centering cam surfaces; wherein the shaft includes one or more stop surfaces, the or each stop surface being associated with respect to the main centering cam surface An angularly displaced and extending parallel to the axis of the shaft; the or each biasing member being arranged to assume a centering, cam surface force to center the clamps in one or more of the positions Wherein the hinge includes a primary biasing member and a primary spring arranged to extend the primary biasing member to engage the primary centering surface to urge the clamps into the closed position;

D wherein the or each stop surface is arranged to engage the primary biasing member to maintain the spindle in a position. Preferably, the biasing member does not intersect the axis of the shaft after stretching. The door is preferably a glass door, more preferably a frameless glass door. Moving the clamp to the open or reposition position will cause the door to be level and closed. The centering surface, particularly the main centering surface, acts as a cam surface as the biasing member rotates during opening or closing of the door. The or each stop surface can be arranged to engage the primary biasing member to maintain the clamp of the chain in the open position. Preferably, the hinge is held in an open position at a right angle to the closed position. Preferably, the or each stop surface is at right angles to the main centering surface 〇 preferably providing two parallel stop surfaces. Preferably there are two open positions which are at right angles on either side of the two sides of the closed position. In this arrangement, the door can remain in an open position at a right angle on either of the two sides of the closed position. Unless a small closing force is applied to the door, this is sufficient for the 10013736# single number A〇101 page 5/65 pages 201224266 to apply the main lug force, otherwise the door attached to the hinge can be in either of two directions The direction remains open. In the following description, the direction toward the biasing member or the piston is referred to as a proximal, and the direction away from the biasing member or the piston toward the rotating shaft is referred to as a distal. In a preferred embodiment, the spindle is arranged such that when the primary centering surface faces proximally toward the biasing member, the or each stop surface will extend straightly relative to the centering surface. A proximal edge of the member and a distal edge facing away from the biasing member. In this position, the stop surface preferably extends from a position remote from the axis of the shaft to a position near the axis of the shaft, or to an axis on the diameter of the shaft parallel to the main centering surface The location on the line. In the latter arrangement, wherein the or both proximal edges are located on a diameter of the shaft in the closed position, the proximal edge being orthogonal to the diameter of the shaft, the or each stop surface preferably being distal to the shaft extend. In this arrangement, due to the abutment between the biasing member and the stop surface, the hinge cannot perform angular rotation beyond the angle of the open position. Rotation of the hinge toward the closed position is facilitated by a biasing member that contacts the proximal edge of the stop surface prior to engagement with the primary centering surface. 1013097133-0 In an alternative embodiment, the proximal edge is located near the diameter of the shaft. In this arrangement the 'stop surface preferably extends proximally at a sufficient distance to provide a reducing force against the hinge turn-off position. The distance between the proximal edge and the diameter (or axis of the shaft) can be selected such that the biasing member provides a reducing force sufficient to allow the door fastened to the hinge to remain in the open position, but this force is not so large It is difficult for the user to close the door. The length of the distance and thus the magnitude of the reducing force may depend on the door's 10013736# single number A〇1 (U Page 6 of 65 201224266 width, door weight and predetermined user strength. In a preferred embodiment The main centering cam surface is located close to the diameter of the shaft. This has several advantages. This promotes the closing of the hinge. The extended length of the spring or other biasing member in use is reduced. This allows for a stronger but less expensive one. The capacity of the lubricant displaced by the spring ◊ during rotation of the shaft is also reduced. "This gives the oil a long working life. ^ Another cam surface can be provided between the near edge of the stop surface and the adjacent edge of the main centering surface. The additional cam surface may be rounded 0 to facilitate smooth opening and closing of the hinge, reducing wear on the contact surface. This allows the use of secondary steel to produce the shaft. The clamp may be adapted to tight the glass door panel The solid meshing glass door panel may have an opening to receive the bolts passing through the clamps. Alternatively or additionally, the clamps may engage the glass door panel by frictional resistance or by using an adhesive. The hinge preferably includes a damping assembly for damping the opening or closing movement of the hinge. Preferably, the biasing assembly includes a damping device to limit the rate at which the hinge rotates, particularly from the open position to the closed position. The damper assembly can also limit the rate of rotation from the partially open position to the fully open position. In a first preferred embodiment, the hinge includes a second biasing member and a second spring that are arranged with one Or a plurality of second centering surfaces are fused 'to cause the door to enter one of the two open positions. The or each second centering surface may be a planar or cylindrical concave surface. Or 'the second set The core surface may comprise a cylindrical member that is parallel to the axis of the shaft and moved away from the axis of the shaft. The use of a cylindrical surface can reach 10013736# single number A0101 page 7 / this shape hundred 1013097133-0 201224266 damping is smooth and moving The component only produces a slight wear advantage. The cylindrical member is preferably located within the circumference of the spindle. In a second alternative preferred embodiment, two _ single The element comprises two biasing members, the first unit comprising a primary biasing member and the second unit comprising a second biasing member. The two units may comprise a lower and upper hinge of the door. In an embodiment, the primary biasing member and the second biasing member are preferably located in the transverse bores, which are arranged to be spaced apart upright, extending radially relative to the axis of the shaft. Preferably, the two biasing members are integrated In a single unit and having a common axis of rotation. Preferably, the two open positions of the hinge are at right angles to the closed position and the two second centering surfaces are orthogonal to the main centering surface and are diametrically opposite each other Relatively 〇pp〇sed. That is to say that the second surfaces can be arranged to face in opposite directions at right angles to the main centering surface. The force of the primary spring is preferably greater than the force of the second spring. In this manner, the hinge moves to the closed position unless the door is at or adjacent to any open position. The hinge thus may comprise an eccentric self-locking device in which it will move into a closed or open position when opened in either direction. The angular position of each center point on each side of the closed position is preferably near the open position. The primary spring can include a pair of concentric springs. The outer spring can be a relatively strong spring to provide a closing force for the hinge. The inner spring may be relatively weak relative to the outer spring and arranged to provide a closing force when facing the biasing member. This check valve will be further described below. 1(10)13736 Sound Order No. A0101 Page 8 of 65 201224266 Each biasing member may comprise a piston mounted in a cylindrical bore for radial movement relative to the shaft. The piston preferably comprises a hollow cylindrical member with a head arranged to engage a corresponding centering surface with a cavity in which a spring is located to urge the piston The outer shaft can be mounted in an upstanding guide slot in the housing that communicates with one or more passages, the or each biasing member being located within the passage to allow hydraulic fluid during hinge activation Or other oil circulation. Ο The spindle preferably includes an attachment adapted to engage the clamp. The end of the shaft may include a head that is arranged to squirt with the socket of one of the clamps such that the shaft and the clamp are forced to rotate together. According to a second aspect of the invention, a glass door hinge shaft includes an axial shaft including an attachment member for engaging the door such that the shaft and the door are forced to rotate together during use; wherein the shaft further comprises: a main centering surface parallel to the axis of the shaft, and two second centering surfaces orthogonal to the main centering surface; wherein the two second centering surfaces are diametrically opposed to the axis An axis of the rod extends; and wherein the shaft includes one or more stop surfaces angularly displaced from the main centering surface at a right angle to the main centering surface and parallel to the rotary pumping line. The or each stop surface is preferably at right angles to the main centering surface. Preferably, the spindle further includes an upper bearing surface and a lower bearing surface adapted to cooperate with the bearing within the hinge body. 10013736#^'^ Α〇101 Page 9 / Total 65 pages 201224266 In a preferred embodiment in which the housing contains two biasing members, the primary centering surface is tilted under the κ mosquito. «, the age to be centered on the surface can be above the second surface. The cavity in the housing containing the shaft and the piston is preferably filled with a hydraulic fluid, such as a lubricating oil. Preferably, the surface of the annular (4) ring is placed between the main centering surface and the second centering surface to be arranged to cooperate with the inner circle surface of the key body to prevent the shaft from being Deformed when in use. The % material can also be used to prevent oil from flowing between the upper and lower portions of the aperture. The shaft rotates as the hinge rotates, causing one piston to retract against the restoring force of the corresponding spring, but at the same time allowing the other piston to expand. Similarly, when the hinge and door are in the closed or open position, the expansion of the piston by the action of its spring causes the door to continue to rotate until it is fully centered in the open or closed position. The piston and the cylindrical sleeve can each provide a damping device. The dimensions of the piston and sleeve can be configured to act as a sliding fit, but greatly prevent oil from flowing between their surfaces as the piston is compressed by rotation of the shaft. Therefore, the oil can be forced through the narrowed groove to damp the movement of the hinge. A groove may be provided to allow oil to pass from the piston cavity through the cavity within the housing as the piston is compressed into the cylindrical sleeve. The tank may include an adjustable valve to regulate the maximum flow of oil. Adjusting the S-thunk valve allows the closing rate of the hinge to be controlled so that the rotational movement of the chain and the door is damped during use. The valve can include a needle valve with a thread. This provides control of the dimensions of the passage from the live 1013097133-0 plug and cylinder to the passage in the hinge housing. 10013736# Single No. A0101 Page 10 of 65 201224266. The oil passing through the needle valve can be allowed to flow to the cavity between the shaft and the head of the piston. The permanent magnets can be located in the cavities or in the cavities within the sleeves or pistons. The permanent magnet can be used to collect any gold > 1 particles formed by the wear of the moving surface when the key is used. The components of this hinge are damaged during the manufacturing process. For example, the spring seat can be magnetic. Ο

In a preferred embodiment the piston of the or each biasing assembly includes a check valve, It is arranged to allow the oil to flow into the cavity as the charm and barrel expand. In this way, Oil will flow from the cavity loop of the piston into the cavity ' between the piston and the shaft during the contraction and expansion period of the piston and return to the piston cavity. In this lion, The amount of the (10) line of the cooked centering surface and the piston increases as Newcastle shrinks. And when the rider expands to the uncentered surface, it can be reduced.  This change in capacity _ 暇 will stop _, To allow oil to circulate during the opening and closing of the hinge and door. The circulation of the oil helps to effectively dampen the hinge.  The main piston can be equipped with - oxygen multiple _, The oil is allowed to flow out of the cavity during the initial compression of the piston.  1013097133-0 In a preferred embodiment, The piston has a head and a cylindrical body,  The cylindrical county _ is set to be red slidable _ branches are accommodated in the cylindrical hole of the sleeve, And having one or more slits at a predetermined axial distance from the head, The slit or slits are held by the sleeve after the body has been slid into the cylindrical sleeve a predetermined distance. This static allows the oil to easily flow out of the piston cavity. Until the piston has retracted to a predetermined extent, After that, the flow of oil will be affected by the obstacles or New Zealand. Thus up to 10013736# single number A〇101 page 11 / a total of 65 pages 201224266 to two-speed damping effect.  The primary check valve can be urged into the remote position by the inner spring of the primary biasing assembly. You can choose the length of the switch. Provide appropriate closing power to the customs. Preferably, The length of the inner magazine is longer than that of the outer bullet.  A cut-away portion may be provided at a distal end of the cylindrical body of the piston, Allowing oil to flow into the piston cavity when the piston is fully extended. At this stage the 'check valve is engaged with the centering surface of the turn.  The cross-sectional area of the cut-away portion may increase from a position in the middle of the head of the piston and the end of the sleeve, So that when the piston extends to a fully extended position, The flow of oil between _ and the installation of the lord can be increased. The cross-sectional shape of the cut portion can be selected, To provide a suitable damping distribution. E.g, Where the object goes to the V-shaped or υ-shaped slit. Alternatively, the cut-out portion may comprise a flat surface formed by removing a sector of the cylindrical sleeve. As another alternative, Parallel sided slots are available.  The hinge of the present invention is a gamma. Wei biased components, Both the opening and closing of the money chain are damped by the circulation of the oil. This is during opening and closing,  Stop the door from closing. Such a slamming of the door may cause the glass door to be broken. Or it may be injurious. The degree of damping of the H_ can be adjusted to regulate the circulation of the oil within the biasing assembly by adjusting the braking activity of the second biasing assembly in the second biasing assembly.  In a preferred aspect of the invention, The hinge further comprises:  The housing ' has a vertical hole;  Axial shaft, It is installed in the hole;  Turn off the device, It is adapted to be coupled to the shaft in the housing, To cause the hinge to reach a closed or centered position;  Page 12 of 65 1〇〇13736#单号 A0101 201224266 Damping# ® 分 , Oh, It is within the housing and is adapted to engage the shaft, Damping the movement of the hinge to the closed position;  ― wherein the shaft has a vertical axis and a first centering cam surface and a first to second cam surface, The centering surfaces are arranged to cause the closing device and the damper to alternately exit the axis when the housing is separately turned away or turned to the closed position relative to the misalignment;  Wherein the closing device comprises a pusher and a spring with at least one closing contact surface, The spring is arranged to urge the contact surface to squirt with the first centering surface;  〇 Its towel herni device contains fluid and silk, The piston includes a piston head and a sleeve slidably mounted within the cylinder. a spring is located within the cylinder. The piston has a projection with a damped contact surface. The damping contact surface is urged by the spring to be in contact with the second centering surface of the shaft, The damping piston includes a check valve;  Wherein the closing device and the damping device extend radially from the axis of the shaft in opposite directions;  The inner surface of the damping piston, The sleeve and the cylindrical barrel form a working fluid (4) - a chamber and the outer surface of the damping piston, The bore and the shaft form a second chamber of the working fluid;  w when the damping piston moves to the axis of the shaft when in use, The working fluid placed in the second chamber passes through the check valve in the damping piston. When the damping piston moves away from the axis of the shaft, The backflow through this check is blocked.  In a particularly preferred embodiment, An adjustable compartment is located in the housing;  The first conduit is in communication between the first chamber and the adjustable _;  a second conduit is in communication between the second chamber and the adjustable valve;  Wake up 373#单号A〇101 Page 13 of 65 page 1013097133-0 201224266 Therefore the adjustment of the valve controls the flow of working fluid from the first chamber to the second chamber to dampen the hinge to close or center s position.  It is preferred to use a single adjustable width. however, If needed,  Two or more adjustable valves can be used.  The hinge according to the embodiment of the present invention has a number of advantages.

The channel or the channel cross-sectional area may vary with the length of the sleeve, For example, stay away from the big, 峨When the _ and the piston are repeatedly retracted away from the shaft, Provide a thief area for fluid flow.  When the damping piston is near the fully compressed position, Fluid can be prevented from flowing through the channel or channels.  The contact surface of the protrusion may be concave or cylindrical. To provide shallow depressions. This can be used to prevent attachment of the cam surface of the shaft. When used continuously, The surface of the cam can be made and the surface of the cam can be flat or curved. The use of a concave or cylindrical surface can be advantageous to ensure that the "bright" surfaces are smoothly and unobstructed when the key is rotated. Avoid excessive compression of the spring' to reduce friction between moving parts. The use of a concave region on the piston pusher provides several advantages. This concave surface helps to dampen the hinges when the hinges are installed. If the (4) center contact surface has become rough or even uneven due to wear, The document was in good contact with the shaft. In addition, The concave surface is used to release the compression of the closing spring. When the hinge is open, This reduction is opened at the door to 75.

When the piston (2 is retracted, The flow through the cut-away portion (21) is suppressed. Then it was completely interrupted.  When the shaft is centered in the closed position, Due to the movement of the spring (25), the piston (16) is stretched, The oil enthalpy contained in the cavity (4〇) of the rotating shaft passes through the slit (19) into the inner cavity (18) of the piston. During the return trip, Since the 6-hp piston is compressed into the sleeve (26), The oil returns to the cavity (4〇), When the shaft rotates during use, Its capacity will increase.  Figures 4 and 5 further illustrate the construction and function of the hinge in accordance with the present invention. Figure 4 contains multiple cross-sectional views. Shows multiple stages of operation of the hinge unit. Figure 5 shows the construction of the spindle in more detail. The same reference numerals are used to denote the components shown in Figs. 1 to 3.  The shaft shown in Figure 5 contains a square head (13). A shaft with a line (53) 0 extends from it. The second centering surfaces (12) are parallel to each other, It extends on the opposite side of the sleeve (53). The second centering surface has a tapered or pointed end (58), To promote engagement with the head of the piston (27), As shown in the cross section A-A of Fig. 4.  The main centering surface (11) is generally planar, And being displaced near the piston (16), So that the piston (16) cannot extend beyond the axis (53), The maximum extent of its extension is not outside the axis (53).  The rear surface (50) is cylindrical, Cooperate with a cylindrical bore (7) that mates with the housing (1). A cylindrical annulus (54) forms an additional bearing surface between the two centering surfaces.  1013097133-0 10013736#单号A01〇l Page 21 of 65 201224266 In the embodiment shown in part B-B of Figure 5, The main centering surface (11) is flat, And extending in parallel with the axis (53). The two stop surfaces (51) are also flat, And extending at right angles to the main centering surface (11), The main centering surface is parallel to the axis (53). The curved cam surface (52) extends between the leading proximal edge (5) of the stop surface (51) and the adjacent edge (57) of the primary centering surface (11). The cam surface (52) makes the hinge unit work more smoothly. And reduce at the edge (55,  57) On the blue. The stop face (5) extends between the proximal edge (55) and the distal edge (56), As shown in the β_β portion of Fig. 5.  In the illustrated embodiment, The shaft has two opposite stop surfaces (51). In an alternative embodiment, For a hinge unit that is suitable for opening in one direction, Only a single stop surface (51) can be used. ^ The Β"-Β" portion of Fig. 5 shows an alternative configuration in which the main centering surface (57) is concave and substantially cylindrical in cross section. The concave surface (10) can cooperate with a matching circular piston head. Alternatively, a piston head of a flat disk shape can be used.  Figure 4 illustrates the function of the hinge. The cross section of the hinge above Β-Β is shown as the ship ι in this position, It is pushed towards the vicinity and the spring (25) is partially _. As shown in the fiber diagram,  When the rotation continues, The door will reach the fully open position. In this position, The stop surface (51) is aligned with the head (17) of the piston (10), The bullet (25) is completely compressed. The flat stop surface (5)) is aligned with the head of the piston to prevent the shaft from rotating. So that the user can let the door open, Let the door stay in the open position. As shown in the B-B section of the fiber surface below, A slight shift in the door allows it to open more completely. however, The cooperation of the piston head (17) and the cylindrical rear surface (10) of the shaft has the following effects: · The door can be freely rotated and the 10013736# single number A〇101 page 22/65 pages 201224266 need not be pushed to the open or closed position . on the other hand, Move to the top of the horizontal plane to ride the __ to allow the door to be completely closed, The piston face (17) and the centering surface (11) are aligned in this position. In this position, The door will be still.  In the first embodiment, The proximal edge (55) of the stop surface (51) is located on the diameter of the shaft parallel to the main centering surface (11). In this arrangement, Further opening the door to a position other than the right angle shown in the cross-sectional view B_B of the following side requires a force to be further compressed to further compress the spring (25). However, to close the door to the position shown in the upper cross-section, There is no need to apply extra force.  In an alternative embodiment, The proximal edge (55) is located near the axis (53). In this arrangement, It takes a little force to shift the door from the right-angled open position. To start the closing movement.  A door including a hinge according to the present invention requires manpower to be opened from a closed position to a right angled position. Opening the door beyond the right angle may require a little extra force. But the spring will not be further compressed, This is due to the cylindrical shape of the distal surface (50) of the shaft.  Therefore, the door can be freely moved beyond the right angle. But when moving from the right angle to the closed position, The door will close automatically.  Figures 6 and 7 illustrate an alternate embodiment, The second centering surface (60) of the shaft is cylindrical and offset from the axis of rotation (53). Preferably,  The cylindrical surface (60) is located around the circumference of the main shaft of the shaft. A continuous surface is formed with the annulus (54). In this embodiment, When the shaft is rotated, the second centering surface (60) produces a precess. This causes the first spring (36) to be retracted or released. The centering surface can be tangential to the surface of the shaft. This arrangement is less prone to mechanical wear than the arrangement shown in Figures 4 and 5 A0101 A Single Number 10013736 Γ Page 23 / Total 65 Page 1013097133-0 201224266. Due to the low flow of displaced oil, Therefore, smoother damping can be provided.  Figures 8 through 14 illustrate embodiments of the invention, The hinge unit is divided into two parts. The first part contains the main centering surface, The second part contains a second damping device.  The brothers 8 to 10 show the main centering unit. This can be located, for example, at the bottom of η. Screw the bottom plate (61) into the housing (62) containing a pair of cylindrical holes (63). A pair of pistons (64) are located in the holes, It is forced by the axial spring (65) to the far side. Mounted on the bearing (67, The shaft (66) in 68) is placed in a vertical hole (69) in the housing (62). The first figure shows the construction of the shaft in detail. The shaft (66) has a square head (79, 〇〇), It has a single centering surface (71) that extends proximally from the axis (72), The piston (not shown) cannot extend as far as the hinge is in use. The stop surface (73) has a proximal edge (75) and a distal edge (76), It is attached to the adjacent edge (77) of the main centering surface (71) by a cam surface (74). As shown in the Β-Β section of Figure 10, The main centering surface (71) has a cylindrical concave shape.  In an alternative embodiment, As shown in Figure 10, , The part shown in the 'main centering surface can be flat (78).  1013097133Ό Figures 11 to 13 show a second damping unit according to the invention. This $ is located, for example, as a squad, To reduce the damping of the scales. Although only a single piston (10) is located in the housing (10), However, the construction of the unit is similar to that shown in Figures 1 to 3. Figure 13 shows the construction of the spindle (82) in more detail. The flattening surface (83) of the m is placed on either side of the two sides of the turn line. The area between the centering surfaces has a miscellaneous or pointed extension (10)' to provide a smooth surface of the rib_piston head (85) 10013736# single number Α〇 101 帛 24 pages / total 65 pages 201224266.  Figure 14 shows the placement of a bearing ring (91, 92) between the columns open > An alternative shaft for the cam surface (90). The cylindrical cam surface (9〇) is offset from the axis of the shaft, Located adjacent to the circumference of the shaft. The rotation of the shaft provides a smooth cylindrical surface (9 inches). When the door is closed or opened, The damping force can be applied smoothly.  Fig. 15 shows the construction of the piston of the damper device as described with reference to Fig. 2. One or more (preferably two) cut-away portions (21) comprise flat or planar portions that are removed from the proximal end of the 0 cylindrical sleeve (27). A concave portion can be used.  Figure 16 shows a perspective view of an alternative hinge in accordance with the present invention. A pair of clamps (1〇1) mounted on the casing (103) form a groove (1〇4), A glass door panel (not shown) can be sprinkled in the tank.  The bottom plate (102) is used as a support member, It is arranged to be fastened to the floor or floor (not shown). As shown in Figure 6, The holder (1〇5) can be fastened within the bottom plate (102) to make the door unit easy to assemble.  Q Figure 17 shows a cross-sectional view of the hinge. The shaft (106) is upright in the hinge body, Extending axially. The rotating shaft (106) is housed in a blind hole (111) in the casing (1〇3), The aperture has a closed upper end (112). A washer (113) seals the shaft and bore to prevent leakage of the working fluid Zhao during use.  A square fixing lug (1〇7) at the lower end of the rotating shaft is accommodated in a socket in which the shape of the holder (1〇5) matches, Prevent the shaft from rotating when in use. Bearing (109, 110) Allowing the housing (103) to rotate about the axis of the spindle.  The closing device (114) is mounted in a generally cylindrical chamber (115) in the housing (1〇3), It extends radially from the hole (in). The chamber (115) is closed by a cylindrical barrel (116) with a threaded end cap. Includes cylindrical 1〇〇13736 sound number A0101 page 25/65 pages^13097133-0 201224266 The closing piston of the sleeve (117) and the piston head (118) is slidably received in the cylinder (116) Inside. The piston head (118) has a projection (119) that extends radially from the chamber (115) through the slot (120) into the aperture (111). a pair of spiral springs (121, 122) extending between the end cap of the cylinder (116) and the rear surface of the piston head (118), The contact surface (125) of the extension (119) is caused to engage the shaft (106).  A cylindrical ring (131) extends radially from the axis of rotation to a circumference adjacent the inner surface of the bore (111). The clearance between the ring (131) and the hole (111) is sufficient for the lubricating fluid to pass through, But small enough to be in normal use, The fluid pressure is prevented from passing from one side of the annulus to the other during opening or closing of the door.  The cavity between the shaft and the hole is thus divided into upper and lower parts. The lower chamber (123) communicates with the forward portion of the chamber (115) located radially inward of the piston head (118) through the slot (120). When the piston head moves radially inward or outward during use, A slot (124) allows working fluid to flow through the piston head. As described below, The upper chamber (130) is similarly communicated with a cylindrical damper chamber in which a damping piston is placed.  The contact surface (125) of the projection (119) is housed on the lower surface of the ring (131), The upper surface of the other lower ring (127) and the socket defined by the generally planar cam surface (126) of the shaft (106).  The cam surface (126) extends parallel to the contact surface (125) of the projection (119) and extends radially outwardly of the axis of the shaft, The contact surface does not extend beyond the axis during use.  As shown in Fig. 20, the plane stop surface (128) extends vertically,  It is at right angles to the cam surface (126). Preferably two stop surfaces are provided. These are used to keep the door open during use.  1QQ13736f单号 A0101 Page 26 of 65 201224266 Open the door to rotate the hinge chain relative to the axis of rotation. Rotation from the closed centering position causes the extension (119) to rotate relative to the cam surface (126), Urging the extension and the piston radially outward to compress the magazine (121,  122). During the piston movement, The working fluid in the chamber (丨15) flows radially inward through the slit (124) in the piston head. Enter the cavity in front of the piston head between the bore and the shaft.  When the door is opened to 90. Time, The hinge will remain open as the end of the extension engages the angled stop surface (128). The slight pressure on the door is enough to release the hinge. The springs then cause the housing to rotate relative to the shaft. The door is returned to the closed centering position without further manpower.  As shown in Fig. 20, one or more intermediate stop surfaces (153) may be provided. The intermediate stop surfaces located at an angle between the main cam surface (126) and the stop surface (128) at right angles enable the damping force to be exerted with the door being quickly closed.  The width or diameter of the planar cam surface (126) is smaller than the diameter of the annulus (127) or (131). Preferably, The diameter of each cam surface is smaller than the diameter of the ring (127) ' (131) or (149). To reduce the wear of these components during use. The diameter of the surface (126) may be 70% to 98% of the diameter of the ring (127), Preferably 80% to 98%, More preferably, it is 85% to 95%.  The reduced diameter shortens the distance between the second stop surfaces (128) and thus reduces the closing spring (121, 122) The extent to which it is compressed in the fully open position of the hinge. The closing force exerted by closing the piston is reduced, As a result, friction and long-term wear between the contact surface (125) and the surface (128) are also reduced.  The damper is located radially in the opposite direction of the closing device (114). 373#单单面1第27页/共65页 1013097133-0 201224266 The damper chamber (129) extends. The damper chamber is axially offset relative to the closed chamber.  A piston including a piston head (132) and a cylindrical sleeve (133) is mounted in the cylinder (134) for slidable movement. The one-way check valve includes a seat (135) and a valve stop (136) located within the piston. A gap (137) in the valve head allows working fluid to pass between the first chamber (138) within the piston and radially toward the second chamber (139) within the piston head (132). The fluid can pass through the valve (135, 136) flowing from the second chamber (139) to the first chamber (138); However, the flow from the first chamber (138) to the second chamber (139) is due to the valve (135, 136) Closed and blocked.  A projection (144) with a radially inwardly facing contact surface G45) extends from the piston head (132). The contact surface (145) can be planar, Lightly concave or with a central cylindrical depression, And is arranged to engage one of the two planar cam surfaces (丨 46) on the spindle. The cam surface (146) extends parallel to the opposite side of the axis of the shaft. It is at right angles to the closing cam surface (126) of the shaft. The stop surface (147) extends at a right angle to the cam surface (146). a second stop surface (148) between the cam surface (ι 46) and the stop surface (147) to form a 6{Γ angle with the cam surfaces, 45.  The angle between the corners of the corners or the 30° angle extends.  In an alternative embodiment, The contact surface may be convex or have an outwardly cylindrical depression.  The upper ring (149) and the ring (131) and the cam surfaces (146) are used to define a socket (15〇), To accommodate the extension (144) when the hinge is rotated. When the door is opened or closed, The hinge housing rotates around the shaft, The closing piston and the damping piston are compressed or expanded, The compression or expansion depends on the orientation of the respective cam table 10013736^'^ Α〇101, which is the orientation of the face of the pistons. When the closing piston is compressed, The damping piston is expanded, Having the working fluid flow radially outward from the chamber (139) into the chamber (138) where the fluid contacts the spring, The main raft is located in the piston.  The cylinder (134) has a slit (143) that communicates with the first conduit (141). The conduit extends from the chamber (129) to a first side of the adjustable screw valve (14A) located in the outer bore of the housing (1〇3). A second conduit (142) extends from a second side of the adjustable valve (14A) to a second chamber (139). When the screw valve is opened, The working fluid can flow from the first chamber - (138) to the second chamber. The valve is partially closed to inhibit fluid flow 'damping the movement of the piston and prevent quick closing.  When the door is closed by hand or the door is released to allow the spring (121, 122) When the force is closed, The damping piston is compressed. The spring (151) is stronger than the spring (121, 122) The force is weak. The spring (151) passes through the compression spring, Used to suppress the opening of the hinge to damp the opening and closing movement of the hinge. During the opening period, further damping can be provided by the friction of the spring. Q can be set with a pair of springs. The weaker spring extends longer. To maintain the damping force over the entire range of motion of the piston.  The fluid pressure in the first chamber (138) increases, And the check valve (135,  136) was also closed, Block fluid from passing through the valve. Due to the increase in pressure, The fluid is forced through a slot (143) in the cylinder and into the conduit (141) in the casing (1〇3). As shown in Figure 17, Fluid passes through the conduit (141) to the first side of the screw valve and into the conduit (142). The conduit returns fluid to the damper chamber (129) of the damper device, Radially facing the piston head, And in the vicinity of the shaft. Adjusting the slit of the screw valve limits the maximum rate at which fluid flows through the valve. As a result, the increased pressure in the chamber (138) inhibits the closing or centering movement of the chain 1013097133-0 1〇〇13736$ single number A0101 29 1 / 65 1 201224266.  The outer surface of the sleeve (133) is provided with a cut-away portion (152), To form a passage that allows fluid to flow from the first chamber (138) to the slit (143) and the valve (140). The cross-sectional area of the passage may vary with the axial length of the sleeve 'which decreases radially inward relative to the shaft, This allows the sleeve (丨33) and the piston head to be compressed and moved away from the shaft to provide a smaller cross-sectional area for fluid flow.  When the damping piston reaches the fully compressed position, Fluid flow is inhibited and can be prevented. With this method, When the hinge is nearly completely closed or centered, The damping force will increase. When it reaches a fully closed or centered position, The closing motion of the chain will be reduced and can be aborted.  When the hinge is opened, The fluid pressure in the second chamber (139) is increased by the pressure of the spring (151) and the piston head (132). Since the ring (131) is adjacent to the inner surface of the hole (111), Therefore, the fluid is prevented from flowing into the operating chamber of the closing device.  With this method, The fluid is retained in the second chamber (139) and flows through the check valve (135, 136). This ensures that an appropriate amount of fluid builds up enough pressure in the first chamber (138) during the return stroke, To force fluid to flow through the adjustable valve (140) and the conduit (141, 142) The defined loop.  Figures 21 to 28 show different configurations of the biasing member comprising the piston with the pusher.  Figure 21 shows the piston of the biasing member comprising the piston head (180),  The piston has a cylindrical sleeve (181) and a rear end (182) extending rearward or proximally. The backend is open, To accommodate the spring (not shown). A projection (183) offset from the axis of the cylindrical sleeve (181) extends forward from the piston head (180). With a flat or flat contact surface (184),  10013736#单号A0101 Page 30 of 65 201224266 It is arranged to harmonize with the surface of the shaft of the shaft (not shown). When in use, Miscellaneous with the cam table (4) to counter the resilience provided by the rotating spring, Moving inward or outward with respect to the axis of the shaft.  Figure 22 shows an alternative piston with a contact surface, The contact surface has a cylindrical concave axial portion (185) between the outer portion (10) of the flat face. The paste galaxie part (185) is used to reduce > Friction caused by the collapse of the bullet (not shown), To reduce wear on moving parts during continuous use.  0 23rd_introduction-step alternative, The flat or planar central portion (187) of the towel is located between the two shoulder positions (189) and the flat or planar outer portion 4 (188). In this arrangement, The central portion (187) extends from the piston head 〇9〇) at a shorter distance than the outer portion (188). To reduce the friction of the spring at maximum compression.  Figure 24 shows a further alternative embodiment, Among the cylindrical convex shapes <»卩. The split (191) extends from the piston head (193) at a greater distance than the two flat or planar outer portions (IQ). Q Figure 25 shows a further embodiment. The axially central portion (194) of the plane is located between the two shoulders (195) and the outer portion (196) of the plane. The central portion (194) of the contact surface extends from the piston head (197) at a greater distance than the outer portions (196). Figure 26 shows a further embodiment in which a continuous cylindrical convex contact surface (198) extends across the entire width of the projection (199). The piston shown in Fig. 27 is similar to that shown in Fig. 21, in which the V-shaped slit (200) that is slid into the sleeve (203) extends from the intermediate position (201) on the sleeve to the rear end that is open rearward. (202). The cross-sectional area of the slit (2〇〇) increases from the front point (201) toward the end (202), so that the flow of oil is 1〇〇13736, the sound number is Α0101, page 31/total 65 pages 201224266 in the piston direction Increases when the shaft moves forward in the axial hole (not shown). Figure 28 shows a further embodiment 'where the sleeve (2〇4) has a flat sector (205) removed therefrom to provide a point (206) from the front of the sleeve to an opening at the rear end ( The groove of 207), the cross-sectional area of the groove increases rearwardly from the point (206) toward the end (207) of the sleeve, allowing more oil to flow as the piston extends toward the shaft in use. Figure 29 shows another embodiment in which the sleeve (2〇8) has a v-shaped slit (209) that extends from an intermediate portion to the opening of the rear end of the piston. The piston head (210) has a projection (2Π) that extends forward to form a contact surface (212). The contact surface (212) has a central axial planar portion (213) having a sloped portion (214) on either side thereof that extends to the outer edge of the projection (211) The outer planar portion (215) is such that the contact surface extends a maximum distance in the radial direction of the axial extension of the piston and the pumping (not shown), and a shorter projection on each outer side (215) ) - formed together.
